Published: 13 January 2020 Shigemitsu Yasuda, Yusuke Hikima, Yusuke Kabeya, Shinichiro Iida, Yoichi Oikawa, Masashi Isshiki, Ikuo Inoue, Akira Shimada & Mitsuhiko Noda BMC Endocrine Disorders volume 20, Article number: 9 (2020) Abstract Background Primary aldosteronism (PA) plus subclinical Cushing’s syndrome (SCS), PASCS, has occasionally been reported. We aimed to clinically characterize patients with PASCS who are poorly profiled. Methods A population-based, retrospective, single-center, observational study was conducted in 71 patients (age, 58.2 ± 11.2 years; 24 males and 47 females) who developed PA (n = 45), SCS (n = 12), or PASCS (n = 14). The main outcome measures were the proportion of patients with diabetes mellitus (DM), serum potassium concentration, and maximum tumor diameter (MTD) on the computed tomography (CT) scans. Results The proportion of DM patients was significantly greater in the PASCS group than in the PA group (50.0% vs. 13.9%, p <  0.05), without a significant difference between the PASCS and SCS groups. Serum potassium concentration was significantly lower in the PASCS group than in the SCS group (3.2 ± 0.8 mEq/L vs. 4.0 ± 0.5 mEq/L; p <  0.01), without a significant difference between the PASCS and PA groups. Among the 3 study groups of patients who had a unilateral adrenal tumor, MTD was significantly greater in the PASCS group than in the PA group (2.7 ± 0.1 cm vs. 1.4 ± 0.1 cm; p <  0.001), without a significant difference between the PASCS and SCS groups. Conclusions Any reference criteria were not obtained that surely distinguish patients with PASCS from those with PA or SCS. However, clinicians should suspect the presence of concurrent SCS in patients with PA when detecting a relatively large adrenal tumor on the CT scans. Peer Review reports Background Primary aldosteronism (PA), an adrenocortical disorder caused by an adrenal tumor that overproduces aldosterone, accounts for 5 to 15% of patients with hypertension [1]. Cushing’s syndrome (CS), an endocrinopathy resulting from the prolonged, excessive adrenocortical secretion of cortisol, falls roughly into the following 2 categories: adrenocorticotropic hormone (ACTH)-dependent CS and ACTH-independent CS; the former includes Cushing’s disease that is primarily caused by a pituitary ACTH-secreting tumor and ectopic ACTH syndrome resulting from extrapituitary ACTH-secreting tumors (eg, bronchial carcinoid) [2], while the latter is usually caused by unilateral adenomas or carcinomas that provoke the autonomous adrenal cortical secretion [3]. Subclinical Cushing’s syndrome (SCS), an ill-defined endocrine disorder leading to the ACTH-independent secretion of cortisol from an adrenal adenoma that is not fully restrained by pituitary feedback [4], is known to cause hypertension, glucose intolerance, and dyslipidemia [5]. The concurrence of clinically overt hyperaldosteronism and subclinical hypercortisolism is rare in PA patients [6]. To date, a few number of studies have examined the clinicopathological features of patients with PA plus SCS (PASCS), the incidences of which have ranged between about 10 and 20% [7, 8]. Lower plasma ACTH levels and a greater tumor size were found in patients with PASCS than in patients with PA alone [8]. In the clinical settings, we rarely encounter PASCS patients who show a small adrenal tumor on the computed tomography (CT) scans and/or do not have a low plasma ACTH level in blood samples collected in the early morning. To examine the clinical features of PASCS patients in the present study, we compared clinical, laboratory, and imaging characteristics among patients with PA, SCS, or PASCS. Methods Patients We conducted a population-based, retrospective, single-center, observational study in 187 patients (119 with PA, 54 with SCS, and 14 with PASCS) at Saitama Medical University Hospital, Saitama, Japan, between January 1999 and December 2016. Hypertensive patients with suspected PA or SCS, as well as normotensive or hypertensive patients with an adrenal incidentaloma were referred to our hospital. A total of 116 patients were excluded from the study: 31 who were diagnosed with PA or SCS only because tests required to definitely diagnose these endocrinopathies were not conducted; 61 who failed to meet the new Japanese diagnostic criteria of SCS [9]; 1 who failed to meet the new Korean diagnostic criteria of subclinical hypercortisolism [10]; and 23 who failed to meet the Japanese [11] and United States [12] diagnostic criteria of PA. Therefore, we investigated 71 patients who were definitely diagnosed with PA and/or SCS (45 with PA, 12 with SCS, and 14 with PASCS). This study was approved by the institutional review board of Saitama Medical University. Patients provided written informed consent to the use of their clinical and laboratory data in the study. Diagnosis of PA and SCS Hormones required for the diagnosis of PA and SCS were assayed according to the procedures described in the pertinent guidelines [9, 11]. Serum cortisol and plasma ACTH levels were determined by electrochemiluminescence immunoassay, plasma aldosterone concentration (PAC) and plasma renin activity (PRA) by radioimmunoassay, and serum dehydroepiandrosterone sulfate (DHEAS) level by chemiluminescent enzyme immunoassay (SRL Inc., Tokyo, Japan). Blood samples were collected in the early morning (7 a.m. to 9 a.m.). PA was suspected when detecting elevated PAC (≥ 150 pg/mL), low PRA (≤ 1.0 ng/mL/hr), and/or the elevated aldosterone-to-renin ratio (> 200). We conducted the following 3 challenge tests in accordance with the Japanese guidelines of PA [11]: captopril challenge test, furosemide upright posture challenge test, and ACTH challenge test. PA was diagnosed when at least 1 of these 3 challenge tests afforded results compatible with the disease. Furthermore, we also referred to the American guideline of PA [12] for selecting only patients who met the diagnostic criteria for PA. Prior to the confirmatory tests, patients had not received any antihypertensive drugs for at least 2 weeks except for those with severe hypertension treated with calcium-channel blockers and/or α-blockers. Adrenal venous sampling (AVS), whose usefulness was well documented in the Japanese and United States guidelines [11,12,13], was conducted in all of patients who had PA or PASCS to make the differential diagnosis of uni- or bilateral aldosterone hypersecretion. The low-dose (1-mg) dexamethasone suppression test (DST) and the corticotropin-releasing hormone (CRH) challenge test were conducted, and the diurnal rhythms of cortisol were also determined—all for the diagnosis of SCS. Moreover, the high-dose (8-mg) DST was also conducted to rule out ACTH-dependent CS. Test results were assessed in accordance with the diagnostic criteria advocated by the Japan Endocrine Society [9] to make the definite diagnosis of SCS. Concretely, patients were required to meet the requisites 1–3)—1) presence of an adrenal incidentaloma; 2) lack of characteristic features of Cushing’s syndrome; and 3) normal basal serum cortisol levels, as well as to have either of the requisites 4–6)—4) the cutoff value of serum cortisol level for the diagnosis of SCS was ≥ 5 μg/dL after the 1-mg DST, 5) the cutoff value of serum cortisol level for the diagnosis of SCS was ≥ 3 μg/dL after the 1-mg DST, and at least 1 of “Low plasma levels of ACTH in the early morning,” “No diurnal changes in serum cortisol levels,” “Unilateral uptake on adrenal scintigraphy,” “Low serum levels of DHEAS,” or the presence of “Transient adrenal insufficiency or atrophy of the attached normal adrenal cortex after removal of the adrenal tumor,” or 6) the cutoff value of serum cortisol level for the diagnosis of SCS was ≥ 1.8 μg/dL after the 1-mg DST, with the presence of “Low plasma levels of ACTH in the early morning” and “No diurnal changes in serum cortisol levels,” or the presence of “Transient adrenal insufficiency or atrophy of the attached normal adrenal cortex after removal of the adrenal tumor.” In the present study, we examined only patients who met the requisites 1–3) and either 1 of the requisites 4–6) as patients with SCS. All patients underwent 128-slice CT of the adrenal glands. 131I-adosterol adrenal scintigraphy was conducted in all of patients who had SCS or PASCS to specify the laterality of the adrenal tumor. Consequently, 7 of 12 patients with SCS and 8 of 14 patients with PASCS underwent adrenalectomy. Postsurgical histopathological examination confirmed cortisol hypersecretion based on the atrophy of the normal area adjacent to the adenoma of the removed adrenal gland [9]. Study outcome measures At the initial visit, all patients were checked up for their age and sex. Systolic blood pressure (SBP), diastolic blood pressure (DBP), and the outcome measures listed in Table 1 were examined in untreated patients. At the time of admission to the hospital for making the definite diagnosis, height and body weight were measured to calculate body mass index (BMI). In the early morning of the next day of admission to the hospital, blood pressures were measured. Blood samples were collected to determine PAC, PRA, as well as plasma ACTH, serum cortisol, and serum DHEAS levels. The laterality of the adrenal tumor was confirmed based on the results from AVS and/or CT. The Hounsfield number and MTD of adrenal tumors were determined on the CT scans. Table 1 Clinical, laboratory, and imaging characteristics of untreated patients with PA, SCS, or PASCS The following terms were defined for PASCS: hypertension, SBP ≥ 140 mmHg and/or DBP ≥ 90 mmHg [14]; diabetes mellitus (DM), an fasting plasma glucose (FPG) level ≥ 126 mg/dL, a 2-h plasma glucose level ≥ 200 mg/dL in the 75-g oral glucose tolerance test, and/or a serum hemoglobin A1c (HbA1c) level ≥ 6.5% in national glycohemoglobin standardization program [15]; and dyslipidemia, a serum triglyceride (TG) level ≥ 150 mg/dL, a serum high-density lipoprotein cholesterol (HDL-C) level < 40 mg/dL, or a serum low-density lipoprotein cholesterol (LDL-C) level ≥ 140 mg/dL [16]. To specify the source of aldosterone hypersecretion by AVS, the following diagnostic criteria were used: 1) the laterality ratio (LR) and the contralaterality ratio (CR) calculated before and after the ACTH challenge test in reference to the Japanese guidelines of PA [11]; 2) the absolute PAC value of ≥ 14,000 pg/mL in reference to the articles of Ohmura [17] and Makita [18]; and 3) the aldosterone ratio of the right and left adrenal veins. According to the Japanese guidelines of PA [11], an LR of > 4 and a CR of < 1 after the ACTH challenge test were used as the cutoff values. Tumor laterality was determined based on a CR of < 1 and the absolute PAC value of ≥ 14,000 pg/mL when the ACTH challenge test indicated an LR of 2 to 4 or a discrepancy occurred in tumor laterality before and after the ACTH challenge test. Since serum cortisol levels considerably differed in the adrenal veins of PASCS patients, the adrenal gland secreting cortisol predominantly was determined based on the aldosterone ratio and on the right-to-left ratio of aldosterone and cortisol in the adrenal veins in reference to the article of Hiraishi et al. [8]. Moreover, tumor laterality was determined based on the results from 131I-adosterol adrenal scintigraphy and on the absolute value of PAC in reference to the articles of Funder et al. [12] and Minami et al. [13]. We did not measure plasma metanephrine concentrations, although the measurement thereof is useful for determining the need for AVS [19] in patients with the suspected concurrence of aldosterone and cortisol hypersecretion. Statistical analyses Continuous and categorical variables were analyzed according to the one-way analysis of variance and Fisher’s exact test, respectively. Two of the 3 study groups were analyzed according to Student’s t-test. Bonferroni’s correction was applied to the p values from Student’s t-test or Fisher’s exact test in multiple comparisons between 2 among the 3 study groups. Blood steroid profiles were compared between 2 groups according to Student’s t-test or the Mann-Whitney U-test. In addition, the multiple linear regression analysis adjusted for age, sex, and BMI was performed to examine differences in MTD and serum potassium concentration among the PA, SCS, and PASCS groups. MTD was not measured in 1 of 42 patients in the PA group who had a unilateral adrenal tumor. Therefore, the data from the patient were excluded as the missing data. A value of p <  0.05 was considered statistically significant. The JMP software version 9.0 (SAS Institute, Cary, NC, USA) was used to make all statistical analyses except multiple linear regression analysis that was performed using the STATA software version 14 (Stata Corp, College Station, TX, USA). Results Study population The clinical, laboratory, and imaging characteristics of 71 patients are shown in Table 1. Mean age was 58.2 ± 11.2 years, females (n = 47, 66.2%) were predominant, and mean BMI was 25.2 ± 4.5 kg/m2. No significant difference was found in age, sex, and BMI among the PA, SCS, and PASCS groups (Table 1). SBP and DBP of patients with untreated hypertension were 165.6 ± 26.1 mmHg and 96.0 ± 13.6 mmHg, respectively, in the PA group in contrast to 145.6 ± 26.9 mmHg and 80.0 ± 12.7 mmHg, respectively, in the SCS groups. DBP was significantly greater (p <  0.01) in the PA group than in the SCS group. Comorbidities are shown in Table 1. Hypertension occurred in 45 (100%), 9 (75.0%), and 13 (92.9%) patients in the PA, SCS, and PASCS groups, respectively. The proportion of patients with hypertension was significantly greater (p <  0.05) in the PA group than in the SCS group; however, no significant difference was found between the PASCS group and the PA group. Notably, the incidence of hypertension was 100% in patients with PA. DM occurred in 6 (14.0%), 6 (50.0%), and 7 (50.0%) patients in the PA, SCS, and PASCS groups, respectively. The proportion of DM patients was significantly greater (p <  0.05) in the PASCS group than in the PA group. Dyslipidemia occurred in 25 (56.8%), 10 (83.3%), and 9 (64.3%) patients in the PA, SCS, and PASCS groups, respectively; however, no significant difference was found among these study groups. Results from laboratory tests are shown in Table 1. FPG was greater not statistically but numerically in the PASCS group than in the PA group (131.6 ± 52.1 mg/dL vs. 103.8 ± 28.5 mg/dL; p = 0.09). On the other hand, FPG was statistically greater in the SCS group than in the PA group (150.0 ± 60.7 mg/dL vs. 103.8 ± 28.5 mg/dL; p <  0.01). HbA1c was greater not statistically but numerically in the PASCS group than in the PA group (6.5 ± 2.1% vs. 5.7 ± 0.9%; p = 0.21). On the other hand, HbA1c was significantly greater in the SCS group than in the PA group (7.3 ± 2.2% vs. 5.7 ± 0.9%; p <  0.01). Serum potassium concentration was significantly lower in the PA group than in the SCS group (3.3 ± 0.7 mEq/L vs. 4.0 ± 0.5 mEq/L; p <  0.01) and in the PASCS group than in the SCS group (3.2 ± 0.8 mEq/L vs. 4.0 ± 0.5 mEq/L; p <  0.01). No significant difference was found in serum potassium concentration between the PA group and the PASCS group. Serum alkaline phosphatase (ALP) level was significantly greater in the PASCS group than in the PA group (279.1 ± 105.4 U/L vs. 212.3 ± 46.3 U/L; p <  0.01). No significant difference was found in serum ALP level between the SCS group and the PASCS group. Subsequently, differences in CT Hounsfield units and MTD of adrenal tumors among the 3 study groups were examined with respect to 65 patients who had a unilateral adrenal tumor (Table 2). MTD on the CT scans was significantly greater in the PASCS group than in the PA group (2.7 ± 0.1 cm vs. 1.3 ± 0.1 cm; p <  0.001) and was also greater in the SCS group than in the PA group (2.7 ± 0.2 cm vs. 1.3 ± 0.1 cm; p <  0.001). No significant difference was found in MTD between the SCS group and the PASCS group. MTD was significantly smaller in the PA group than in the other 2 groups, was second smallest in the SCS group, and was largest in the PASCS group (Table 2). MTD ranged as follows: 0.3–2.2 cm, 1.8–3.5 cm, and 1.1–5.0 cm in the PA, SCS, and PASCS groups, respectively (Fig. 1). Table 2 Maximum tumor diameters and computed tomography Hounsfield units of adrenal tumors in patients who had a unilateral adrenal tumor Full size table Fig. 1 Maximum tumor diameters in patients with PA, SCS, or PASCS who had a unilateral adrenal tumor. PA, primary aldosteronism; SCS, subclinical Cushing’s syndrome, PASCS, primary aldosteronism plus subclinical Cushing’s syndrome The blood steroid profiles of patients with PA or PASCS are shown in Table 3. PAC was significantly greater in the PASCS group than in the PA group (255.0 [713.3–153.5] vs. 208.0 [273.0–159.8]; p <  0.005). No significant difference was found in PRA in the morning, while the PAC/PRA ratio was significantly greater in the PASCS group than in the PA group (1450.0 [5010.0–529.4] vs. 1258.3 [1956.3–643.1]; p <  0.005). The PAC/PRA ratio in the captopril challenge test was significantly greater in the PASCS group than in the PA group (3028.5 ± 3648.9 vs. 730.7 ± 745.7; p <  0.001) as with PAC in the captopril challenge test (348.6 ± 340.1 vs. 149.0 ± 94.2; p <  0.005). Serum cortisol level was significantly greater in the PASCS group than in the PA group (16.4 ± 6.6 μg/dL vs. 12.4 ± 4.3 μg/dL; p <  0.05). The mean serum cortisol level was 17.8 ± 5.9 μg/dL in the SCS group and was not significantly greater in the SCS group than in the PASCS group (17.8 ± 5.9 μg/dL vs. 16.4 ± 6.6 μg/dL; p = 0.49). No significant difference was found in plasma ACTH and serum DHEAS levels in the early morning; however, these variables were not significantly lower in the PASCS than in the PA group (p = 0.29 for ACTH and p = 0.40 for DHEAS). On the other hand, the peak plasma ACTH levels in the CRH challenge test were significantly lower in the PASCS group than in the PA group (18.9 ± 8.9 vs. 57.1 ± 10.8; p <  0.005) (Table 3) and were not significantly greater in the SCS group than in the PASCS group (15.3 ± 5.6 μg/dL vs. 18.9 ± 8.9 μg/dL; p = 0.64). Table 3 Blood steroid profiles of patients with PA or PASCS Full size table Multiple linear regression analysis on MTD and serum potassium concentration with respect to patients in the PA, SCS, and PASCS groups who had a unilateral adrenal tumor MTD was significantly greater in the PASCS and SCS groups than in the PA group with respect to patients who had a unilateral adrenal tumor (Table 2). Therefore, we conducted a multiple linear regression analysis adjusted for age, sex, and BMI to examine differences in MTD among the PA, SCS, and PASCS groups. Consequently, MTD was significantly smaller in the PA group than in the PASCS group (difference, – 1.19 cm; 95% CI, – 1.66 to – 0.72 cm). However, no significant difference was found in MTD between the SCS group and the PASCS group (Table 4). Serum potassium concentration was significantly greater in the SCS group than in the PASCS group (difference, 0.97 mEq/L; 95% CI, 0.38 to 1.54 mEq/L). However, no significant difference was found in serum potassium concentration between the PASCS group and the PA group (Table 4). Table 4 Multiple regression analysis on maximum tumor diameter and serum potassium concentration with respect to patients in the PA, SCS, and PASCS groups who had a unilateral adrenal tumor (n = 65) Full size table The cutoff value of 2.4 cm for tumor size seemed to produce the largest proportion of classified patients (91.0%). Patients with PA who had a tumor size of > 2.4 cm almost certainly had the elements of PASCS (specificity 100%). Namely, the sensitivity and specificity were calculated to be 58.0 and 100%, respectively, when the cutoff point for tumor diameter was set to 2.4 cm. The odds ratio for tumor diameter when comparing PA with PASCS was 0.06 (95% CI, 0.006–0.261). Discussion We found several clinical and laboratory differences between patients with PASCS and patients with either PA or SCS. Regarding the impact of PA and SCS on glucose metabolism, the risk of developing DM in SCS is enhanced by the overproduction of cortisol that leads to increased gluconeogenesis [20]. Moreover, the risk is also enhanced by PA through 1) a hypokalemia-induced decrease in initial pancreatic insulin release and 2) a reduction in insulin sensitivity [21,22,23]. Hypokalemia is caused by the mineralocorticoid receptor-mediated overexcretion of potassium from the kidneys in both hypercortisolism and hyperaldosteronism [12, 24, 25]. Serum potassium concentration decreased significantly in the PA group than in the SCS group (p <  0.01). Similarly, the concurrence of PA and SCS significantly decreased serum potassium concentration against the SCS group (p <  0.01), but not the PA group. Of special note was the fact that the PASCS group involving both hyperaldosteronism and hypercortisolism did not show any greater decrease in serum potassium concentration as compared with the PA group. The mineralocorticoid receptors (MRs) bind both mineralocorticoids and glucocorticoids with high affinity (deoxycorticosterone = corticosterone ≥ aldosterone = cortisol) [26]. On the other hand, a cortisol-degrading enzyme—11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2)—is expressed in renal epithelial cells and regulates the binding of aldosterone to the MRs by impeding cortisol binding to the MRs through the inactivation of cortisol to cortisone [26, 27]. Namely, this physiological event explains the MR-mediated renal excretion of potassium that is enhanced by both cortisol and aldosterone. We hypothesize that the renal potassium excretion-enhancing activity is greater for aldosterone than for cortisol due to the 11β-HSD2-induced, extensive inactivation of cortisol and that the hyperaldosteronism-enhanced renal excretion of potassium in patients with PASCS becomes more apparent, with the less effect of hypercortisolism on renal potassium excretion. Zallocchi et al. [28] described that renal 11β-HSD2 activity is regulated by glucocorticoids, is downregulated following adrenalectomy, and is restored by corticosterone replacement. These findings lead us to hypothesize that 11β-HSD2 may suppress the binding of corticosteroids to the MRs almost completely in subclinical hypercortisolism or that the expression/activity of renal 11β-HSD2 may be increased in PA. However, these hypotheses require further research for its demonstration. The proportion of DM patients increased significantly in the PASCS group than in the PA group (p <  0.05), which is in line with a previous study that described abnormal glucose metabolism in PA patients with cortisol hypersecretion [29]. Hyperaldosteronism found in patients with PA also induces abnormal glucose metabolism [21,22,23], although being less intense as compared with hypercortisolism found in patients with SCS. The proportions of DM patients in the PA and SCS groups increased, which resulted to nullify a statistically significant difference in the proportion of DM patients between the 2 study groups. The fact that the risk for DM is increased in PA patients with mild glucocorticoid excess has been reported [30,31,32]; the finding was also described in Japanese patients with PA and patients with PASCS [33]. Interestingly, patients with PASCS involving hypercortisolism- and hyperaldosteronism-induced hypokalemia showed neither additive or synergic impact on abnormal glucose metabolism contrary to our prediction. The proportion of DM patients was comparable between the PASCS group and the SCS group. However, the reason for these findings is unknown, awaiting the further accumulation of clinical evidence. MTD was significantly smaller (p <  0.001) in the PA group than in the PASCS or SCS group, and multiple regression analysis on MTD revealed that MTD was significantly larger by 1.2 cm in the PASCS group than in the PA group (p <  0.001). Previous studies [8, 34] examined the clinical characteristics of patients with PA or PASCS and described significant differences in MTD between the 2 study groups. Their results were concordant with and support our results that indicated no significant difference in MTD between the PASCS group and the SCS group. Most of previous clinical studies in patients with SCS have described adrenal tumors of ≥ 2 cm in diameter [35, 36]. In addition, an adrenal adenoma causing the overproduction of both cortisol and aldosterone is considered to have a ≥ 2.5 cm diameter [34]. In the present study, however, the adrenal tumor was smaller in both patients with SCS and patients with PASCS. Concretely, the smallest MTD was 1.1 cm in patients with PASCS (Fig. 1). None of patients, who had PA and an adrenal tumor < 1 cm in diameter, developed SCS. Therefore, the dexamethasone suppression test may not be required for them. Regarding bone metabolism impairment in SCS, the risk of developing osteoporosis is enhanced by the overproduction of cortisol in SCS [37, 38]. On the other hand, hyperaldosteronism is also known to increase the risk for osteoporosis [39]. SCS and PA are the risk factors for a reduction in BMD and an increase in vertebral fracture [37,38,39]. In the present study, serum ALP level was significantly greater in the PASCS group than in the PA group (p <  0.01). No significant difference was found in serum ALP level between the SCS group and the PASCS group. If this ALP represents bone alkaline phosphatase (BAP), the deleterious effects of hyperaldosteronism on bone metabolism might be masked by the severe abnormalities of bone metabolism caused by hypercortisolism in patients with PASCS. However, the relevant effects are difficult to assess by means of bone metabolism markers [eg, BAP] in patients with hypercortisolism as found in SCS [37]. Unfortunately, we neither used bone metabolism markers, nor measured BMD. Therefore, we will intend to investigate these variables in the future. Limitations The present study has several limitations. First, the study was retrospective in design and had a relatively small number of patients. Therefore, selection bias and sampling bias cannot be discarded. Second, not all patients underwent AVS or had a histopathological diagnosis. Patients, to whom challenge tests for either PA or SCS were conducted, were not included in the present study. Hence, the number of patients resulted to be relatively small. Third, the lack of data in the present study impeded the analysis of BMD and bone metabolism markers. Fourth, 131I-adosterol adrenal scintigraphy is not only useful for the diagnosis of SCS, but also is a very important imaging modality to predict postsurgical hypoadrenalism [40]. However, we could not investigate the latter. Conclusions We could not obtain any reference criteria to surely distinguish patients with concurrent endocrinopathies from those with a single endocrinopathy. However, clinicians should suspect the presence of concurrent SCS in patients with PA when detecting an adrenal tumor (≥ 1 cm in diameter) on the CT scans.

  8. Houston Methodist neurosurgeons and neuroscientists are looking at a new way to classify pituitary tumors that could lead to more precise and accurate diagnosing for patients in the future. Found in up to 10% of the population, pituitary tumors, also called adenomas, are noncancerous growths on the pituitary gland and very common. Although these pituitary tumors are benign in nature, they pose a major health challenge in patients. The new tests being investigated at Houston Methodist not only have the potential to lead to better diagnoses for patients with pituitary adenomas, but also for many other types of brain tumors in the future. The findings, which were published Jan. 28 in Scientific Reports, an online journal from Nature Publishing Group, describe a new way being looked at to study the blood of patients with pituitary tumors to determine exactly what tumor type they have and whether they might respond to medical treatment rather than surgery. "Often called the 'master gland,' the pituitary gland controls the entire endocrine system and regulates various body functions by secreting hormones into the bloodstream to control such things as metabolism, growth and development, reproduction and sleep," said corresponding author Kumar Pichumani, Ph.D., a research physicist at the Houston Methodist Research Institute. "When pituitary adenomas occur, they may secrete too much of one or more hormones that could lead to a variety of issues, ranging from infertility and sexual dysfunction to vision problems and osteoporosis, among many other health problems." Neurosurgeon David S. Baskin, M.D., director of the Kenneth R. Peak Center for Brain and Pituitary Tumor Treatment and Research in the Department of Neurosurgery at Houston Methodist Hospital, collaborated with Pichumani on this study. He said some pituitary tumors can be treated with medication rather than surgery, but a precise diagnosis of the type of tumor someone has and what hormone it's secreting is essential for proper treatment. This is sometimes very difficult to do based on standard endocrine hormone testing. "To guide our decisions on diagnosis and treatment, we currently rely on a blood-based hormone panel test that measures the levels of hormones in the blood to determine which hormones are overproducing in the tumor," Baskin said. "However, some tumors secrete too much of more than one hormone, making this test ambiguous for diagnosis." Led by Pichumani and Baskin, a team of researchers from the Peak Brain and Pituitary Tumor Treatment and Research Center and Houston Methodist Neurological Institute studied 47 pituitary adenoma patients of different subtypes by collecting blood during surgery to remove their tumors. They confirmed that elevated blood levels of a non-hormonal compound called betahydroxybutyrate, also known as BHB, was found only in patients with the prolactinoma subtype of noncancerous pituitary gland brain tumor that overproduces the hormone prolactin. This compound is known to supply energy to the brain during starvation, which led the researchers to speculate that BHB might be providing non-hormonal energy to these prolactinoma tumors causing them to grow and spread. The discovery could be further developed into a diagnostic lab test. This study is part of a developing field called metabolomics in which researchers study small molecules in tumors to see what's unique about their metabolism and how they're used as nutrients to supply energy. This contributes to better diagnoses and discovering new ways to kill tumors by poisoning the specific energy they use without causing damage to normal cells. The researchers are now enrolling more patients in a larger study currently underway to validate the results of their pilot study. If successful, they say BHB could be used as a non-hormonal metabolic biomarker for prolactinoma pituitary tumor diagnosis and prognosis to supplement the current hormone panel tests. They're also looking for biological reasons why only prolactin-secreting tumors have elevated BHB blood levels to inform therapeutic intervention.

  9. January 19, 2020 Adrenococortical carcinoma (ACC) is a rare cancer, occurring at the rate of one case in two million person years. Cushing syndrome or a mixed picture of excess androgen and glucocorticoid production are the most common presentations of ACC. Other uncommon presentations include abdominal pain and adrenal incidentalomas. In the present report, a 71-year-old male presented with abdominal pain and was eventually diagnosed with ACC. He was found to have pulmonary thromboembolism following an investigation for hypoxemia, with the tumor thrombus extending upto the right atrium. This interesting case represents the unique presentation of a rare tumor, which if detected late or left untreated is associated with poor outcomes, highlighting the need for a low index of suspicion for ACC when similar presentations are encountered in clinical practice. ACC is a rare but aggressive tumor. ACC commonly presents with rapid onset of hypercortisolism, combined hyperandrogenism and hypercortisolism, or uncommonly with compressive symptoms. Clinicians should have a low index of suspicion for ACC in patients presenting with rapid onset of symptoms related to hypercortisolism and/or hyperandrogenism. Venous thromboembolism and extension of the tumor thrombus to the right side of the heart is a very rare but serious complication of ACC that clinicans should be wary of. The increased risk of venous thromboembolism in ACC could be explained by direct tumor invasion, tumor thrombi or hypercoagulability secondary to hypercortisolism. Early diagnosis and prompt treatment can improve the long-term survival of patients with ACC.

  11. Lacroix A, et al. Pituitary. 2019;doi:10.1007/s11102-019-01021-2. January 7, 2020 Andre Lacroix Most adults with persistent or recurrent Cushing’s disease treated with the somatostatin analogue pasireotide experienced a measurable decrease in MRI-detectable pituitary tumor volume at 12 months, according to findings from a post hoc analysis of a randomized controlled trial. “Pasireotide injected twice daily during up to 12 months to control cortisol excess in patients with residual or persistent Cushing's disease was found to reduce the size of pituitary tumors in a high proportion of the 53 patients in which residual tumor was still visible at initiation of this medical therapy,” Andre Lacroix, MD, FCAHS, professor of medicine at the University of Montreal Teaching Hospital in Montreal, Canada, told Healio. “Pituitary tumors causing Cushing's syndrome which cannot be removed completely by surgery have the capacity to grow in time, and a medical therapy that can reduce tumor growth in addition to control excess cortisol production should be advantageous for the patients.” Lacroix and colleagues analyzed data from 53 adults with persistent or recurrent Cushing’s disease, or those with newly diagnosed Cushing’s disease who were not surgical candidates, who had measurable tumor volume data (78% women). Researchers randomly assigned participants to 600 g or 900 g subcutaneous pasireotide (Signifor LAR, Novartis) twice daily. Tumor volume was assessed independently at 6 and 12 months by two masked radiologists and compared with baseline value and urinary free cortisol response. Most adults with persistent or recurrent Cushing’s disease treated with the somatostatin analogue pasireotide experienced a measurable decrease in MRI-detectable pituitary tumor volume at 12 months. Source: Shutterstock Researchers found that reductions in tumor volume were both dose and time dependent. Tumor volume reduction was more frequently observed at month 6 in the 900 g group (75%) than in the 600 g group (44%). Similarly, at month 12 (n = 32), tumor volume reduction was observed more frequently in the 900 g group (89%) than in the 600 g group (50%). Results were independent of urinary free cortisol levels. The researchers did not observe a relationship between baseline tumor size and change in tumor size. “Taken together, the results of the current analysis demonstrate that treatment with pasireotide, a pituitary-directed medical therapy that targets somatostatin receptors, can frequently lead to radiologically measurable reductions in pituitary tumor volume in patients with Cushing’s disease,” the researchers wrote. “Tumor volume reduction is especially relevant in patients with larger microadenomas, suggesting that pasireotide is an attractive option for these patients, especially in cases in which patients cannot undergo transsphenoidal surgery or do not respond to surgical management of disease.” – by Regina Schaffer For more information: Andre Lacroix, MD, FCAHS, can be reached at the University of Montreal Teaching Hospital, Endocrine Division, 3840 Saint-Urbain, Montreal, H2W 1T8, Canada; email: andre.lacroix@umontrael.ca.

January 5, 2020 Obesity is common at diagnosis of pituitary adenoma in childhood and may persist despite successful treatment, according to findings published in Clinical Endocrinology. “The importance of childhood and adolescent obesity on noncommunicable disease in adult life is well recognized, and in this new cohort of patients, we report that obesity is common at presentation of pituitary adenoma in childhood and that successful treatment is not necessarily associated with weight loss,” Aashish Sethi, MD, MBBS, a pediatric endocrinologist in the department of endocrinology at Alder Hey Children’s Hospital in Liverpool, United Kingdom, and colleagues wrote. “We have reported obesity, and obesity-related morbidity in a mixed cohort of children and young adults previously, but [to] our knowledge, this is the first time this observation has been reported in a purely pediatric cohort.” In a retrospective study, Sethi and colleagues analyzed clinical and radiological data from 24 white children from Alder Hey Children’s Hospital followed for a median of 3.3 years between 2000 and 2019 (17 girls; mean age at diagnosis, 15 years). Researchers assessed treatment modality (medical, surgical or radiation therapy), pituitary hormone deficiencies and BMI, as well as results of any genetic testing. Within the cohort, 13 girls had prolactinomas (mean age, 15 years), including 10 macroadenomas between 11 mm and 35 mm in size. Children presented with menstrual disorders (91%), headache (46%), galactorrhea (46%) and obesity (38%). Nine children were treated with cabergoline alone, three also required surgery, and two were treated with the dopamine agonist cabergoline, surgery and radiotherapy. Five children had Cushing’s disease (mean age, 14 years; two girls), including one macroadenoma. Those with Cushing’s disease presented with obesity (100%), short stature (60%) and headache (40%). Transsphenoidal resection resulted in biochemical cure; however, two patients experienced relapse 3 and 6 years after surgery, respectively, requiring radiotherapy. One patient also required bilateral adrenalectomy. Six children had a nonfunctioning pituitary adenoma (mean age, 16 years; two girls), including two macroadenomas. These children presented with obesity (67%), visual field defects (50%) and headache (50%). Four required surgical resections, with two experiencing disease recurrence after surgery and requiring radiotherapy. During the most recent follow-up exam, 13 children (54.1%) had obesity, including 11 who had obesity at diagnosis. “The persistence of obesity following successful treatment, in patients with normal pituitary function, suggests that mechanisms other than pituitary hormone excess or deficiency may be important,” the researchers wrote. “It further signifies that obesity should be a part of active management in cases of pituitary adenoma from diagnosis.” – by Regina Schaffer Disclosures: The authors report no relevant financial disclosures.

  13. A diagnostic technique called bilateral inferior petrosal sinus sampling (BIPSS), which measures the levels of the adrenocorticotropic hormone (ACTH) produced by the pituitary gland, should only be used to diagnose cyclic Cushing’s syndrome patients during periods of cortisol excess, a case report shows. When it is used during a spontaneous remission period of cycling Cushing’s syndrome, this kind of sampling can lead to false results, the researchers found. The study, “A pitfall of bilateral inferior petrosal sinus sampling in cyclic Cushing’s syndrome,” was published in BMC Endocrine Disorders. Cushing’s syndrome is caused by abnormally high levels of the hormone cortisol. This is most often the result of a tumor on the pituitary gland that produces too much ACTH, which tells the adrenal glands to increase cortisol secretion. However, the disease may also occur due to adrenal tumors or tumors elsewhere in the body that also produce excess ACTH — referred to as ectopic Cushing’s syndrome. Because treatment strategies differ, doctors need to determine the root cause of the condition before deciding which treatment to choose. BIPSS can be useful in this regard. It is considered a gold standard diagnostic tool to determine whether ACTH is being produced and released by the pituitary gland or by an ectopic tumor. However, in people with cycling Cushing’s syndrome, this technique might not be foolproof. Researchers reported the case of a 43-year-old woman who had rapidly cycling Cushing’s syndrome, meaning she had periods of excess cortisol with Cushing’s syndrome symptoms — low potassium, high blood pressure, and weight gain — followed by normal cortisol levels where symptoms resolved spontaneously. In general, the length of each period can vary anywhere from a few hours to several months; in the case of this woman, they alternated relatively rapidly — over the course of weeks. After conducting a series of blood tests and physical exams, researchers suspected of Cushing’s syndrome caused by an ACTH-producing tumor. The patient eventually was diagnosed with ectopic Cushing’s disease, but a BIPSS sampling performed during a spontaneous remission period led to an initial false diagnosis of pituitary Cushing’s. As a result, the woman underwent an unnecessary exploratory pituitary surgery that revealed no tumor on the pituitary. Additional imaging studies then identified a few metastatic lesions, some of which were removed surgically, as the likely source of ACTH. However, the primary tumor still hasn’t been definitively identified. At the time of publication, the patient was still being treated for Cushing’s-related symptoms and receiving chemotherapy. There is still a question of why the initial BIPSS result was a false positive. The researchers think that the likely explanation is that BIPSS was performed during an “off phase,” when cortisol levels were comparatively low. In fact, a later BIPSS performed during a period of high cortisol levels showed no evidence of ACTH excess in the pituitary. This case “demonstrates the importance of performing diagnostic tests only during the phases of active cortisol secretion, as soon as first symptoms appear,” the researchers concluded.

  17. Approximately 20% of a cohort of adults with Cushing’s syndrome experienced at least one thrombotic event after undergoing pituitary or adrenal surgery, with the highest risk observed for those undergoing bilateral adrenalectomy, according to findings from a retrospective analysis published in the Journal of the Endocrine Society. “We have previously showed in a recent meta-analysis that Cushing’s syndrome is associated with significantly increased venous thromboembolic events odds vs. the general population, though the risk is lower than in patients undergoing major orthopedic surgery,” Maria Fleseriu, MD, FACE, professor of neurological surgery and professor of medicine in the division of endocrinology, diabetes and clinical nutrition in the School of Medicine at Oregon Health & Science University and director of the OHSU Northwest Pituitary Center, told Healio. “However, patients undergoing many types of orthopedic surgeries have scheduled thromboprophylaxis, especially postsurgery, which is not the standard of care in patients with Cushing’s syndrome. In this study, we wanted to look in more detail at the rates of all thrombotic events, both arterial and venous, in patients at our specialized pituitary center over more than a decade.” In a retrospective, longitudinal study, Fleseriu and colleagues analyzed data from 208 individuals with Cushing’s syndrome undergoing surgical (pituitary, unilateral and bilateral adrenalectomy) and medical treatment at a single center (79.3% women; mean age at presentation, 45 years; mean BMI, 33.9 kg/m²; 41.8% with diabetes). Individuals with severe illness and immediate mortality were excluded. Thromboembolic events (myocardial infarction, deep venous thrombosis [DVT], and pulmonary embolism or stroke) were recorded at any point up until last patient follow-up. Researchers assessed all patients who received anticoagulation in the immediate postoperative period and up to 3 months after surgery, recording doses and complications for anticoagulation. Within the cohort, 39 patients (18.2%) experienced at least one thromboembolic event (56 total events; 52% venous), such as extremity DVT (32%), cerebrovascular accident (27%), MI (21%), and pulmonary embolism (14%). Of those who experienced a thromboembolic event, 40.5% occurred within 60 days of surgery. Researchers found that 14 of 36 patients who underwent bilateral adrenalectomy experienced a thromboembolic event, for an OR of 3.74 (95% CI, 1.69-8.27). Baseline 24-hour urinary free cortisol levels did not differ for patients with or without thromboembolic event after bilateral adrenalectomy. “Despite following these patients over time, results almost surprised us,” said Fleseriu, also an Endocrine Today Editorial Board Member. “The risk of thromboembolic events in patients with Cushing’s syndrome was higher than we expected, approximately 20%. Many patients had more than one event, with higher risk at 30 to 60 days postoperatively. Use of a peripherally inserted central catheter line clearly increased risk of upper extremity DVT.” Among 197 patients who underwent surgery, 50 (25.38%) received anticoagulation after surgery with 2% experiencing bleeding complications. “We clearly need to understand more about what happens in patients with Cushing’s syndrome for all comorbidities, but especially thrombosis, and find the factors that predict higher risk and use anticoagulation in those patients,” Fleseriu said. “We have shown that among patients who had anticoagulation, risks were minimal. We also have to think more about timelines for these thromboembolic events and the duration of anticoagulation, and probably to expand it up to 30 to 60 days postoperatively if there are no contraindications, especially for patients undergoing bilateral adrenalectomy.” Fleseriu cautioned that the findings do not necessarily suggest that every individual with Cushing’s syndrome needs anticoagulation therapy, as the study was retrospective. Additionally, sex, age, BMI, smoking status, estrogen or testosterone supplementation, diabetes and hypertension — all known factors for increased thrombosis risk among the general population — were not found to significantly increase the risk for developing a thromboembolic event, Fleseriu said. “As significantly more patients have exogenous Cushing’s syndrome than endogenous Cushing’s syndrome and many of these patients undergo surgeries, we hope that our study increased awareness regarding thromboembolic risks and the need to balance advantages of thromboprophylaxis with risk of bleeding,” Fleseriu said. – by Regina Schaffer For more information: Maria Fleseriu, MD, FACE, can be reached at fleseriu@ohsu.edu.

    On December 12th, I am speaking at a sold-out event. I am telling half a funny story and posting it on YouTube. If people want to hear the rest they have to visit my website which is all about Cushing's. Everyday, I see people with Cushing's that don't know they have it. I want to reach these people and the general public to make them aware of our disease. I need a title for this video and am looking for your suggestions. The story is similar to the Abbott and Costello routine of Who's on first and What's on second. So far, I thought of: Is it obesity or Cushing's Disease? What would you suggest as an attention getter? When I post this video, I need your support to view it and go to my website to hear the rest of the story. If you could share the video and ask family and friends to do the same I would appreciate that. Wouldn't it be great if this went viral. So many people would learn about Cushings. WE can make this happen if we involve enough people. Lets go for it. Thanks again. Looking forward to those new titles..

  21. I am looking for some place like The Mayo clinic or Endocrinologists that would be interested in setting up a dietary study with their Cushing's patients, I am having great success with my specialized diet in lessening the symptoms of cushing's and want to help others get a better quality of life while living with this disease. The first picture is me with Cushing's in 2013 before surgery. the next two pictures are me now with a cushing's recurrence while on my specialized diet. For 3 years I used my body as a science experiment with foods. I don't have a moon face, I have not gained any weight, my girth is much less and my energy and strength are much better than the first time I had Cushing's. The only difference is my diet. For 2 years my endo refused to test me for cushing's again because I did not look the way I should. I had to get other doctors to do the first and secong level tests then I brought those results to my endo and asked him to do the dex suppression test. All tests confirmed Cushing's recurrence. He still won't believe me that my diet has anything to do with the way I look or feel. I am the proof, but he still wont beieve me. What will it take for people to listen to us and believe us????

    I believe I need legal assistance related to i humane treatment by city and/or county officials. I can explain further, if need be, once I find out if it’s even possible to get help. And I certainly cannot afford to pay an attorney, since my income is SSD (Disability), which is low and fixed, which has been the case since Cushing’s reared it’s remorseless, destructive head in 2008. Is there any legal assistance fund set up for Cushing’s patients?
  24. Written by Kathleen Doheny with Maria Fleseriu, MD, FACE, and Vivien Herman-Bonert, MD Cushing's disease, an uncommon but hard to treat endocrine disorder, occurs when a tumor on the pituitary gland, called an adenoma—that is almost always benign—leads to an overproduction of ACTH (adrenocorticotropic hormone), which is responsible for stimulating the release of cortisol, also known as the stress hormone. Until now, surgery to remove the non-cancerous but problematic tumor has been the only effective treatment. Still, many patients will require medication to help control their serum cortisol levels, and others cannot have surgery or would prefer to avoid it. Finally, a drug proves effective as added on or alternative to surgery in managing Cushing's disease. Photo; 123rf New Drug Offers Alternative to Surgery for Cushing's Disease Now, there is good news about long-term positive results achieved with pasireotide (Signifor)—the first medication to demonstrate effectiveness in both normalizing serum cortisol levels and either shrinking or slowing growth of tumors over the long term.1,2 These findings appear in the journal, Clinical Endocrinology, showing that patients followed for 36 months as part of an ongoing study had improved patient outcomes for Cushing’s disease.2 "What we knew before this extension study was—the drug will work in approximately half of the patients with mild Cushing's disease," says study author Maria Fleseriu, MD, FACE, director of the Northwest Pituitary Center and professor of neurological surgery and medicine in the division of endocrinology, diabetes and clinical nutrition at the Oregon Health and Sciences University School of Medicine. “Pasireotide also offers good clinical benefits," says Dr. Fleseriu who is also the president of the Pituitary Society, “which includes improvements in blood pressure, other signs and symptoms of Cushing’s symptom], and quality of life.”2 What Symptoms Are Helped by Drug for Cushing's Disease? Among the signs and symptoms of Cushing’s disease that are lessened with treatment are:3 Changes in physical appearance such as wide, purple stretch marks on the skin (eg, chest, armpits, abdomen, thighs) Rapid and unexplained weight gain A more full, rounder face Protruding abdomen from fat deposits Increased fat deposits around the neck area The accumulation of adipose tissue raises the risk of heart disease, which adds to the urgency of effective treatment. In addition, many individuals who have Cushing’s disease also complain of quality of life issues such as fatigue, depression, mood and behavioral problems, as well as poor memory.2 As good as the results appear following the longer term use of pasireotide,2 Dr. Fleseriu admits that in any extension study in which patients are asked to continue on, there are some built-in limitations, which may influence the findings. For example, patients who agree to stay on do so because they are good responders, meaning they feel better, so they’re happy to stick with the study. “Fortunately, for the patients who have responded to pasireotide initially, this is a drug that can be continued as there are no new safety signals with longer use," Dr. Fleseriu tells EndocrineWeb, "and when the response at the start is good, very few patients will lose control of their urinary free cortisol over time. That's a frequent marker used to monitor patient's status. For those patients with large tumors, almost half of them had a significant shrinkage, and all the others had a stable tumor size." What Are the Reasons to Consider Drug Treatment to Manage Cushing’s Symptoms The extension study ''was important because we didn't have any long-term data regarding patient response to this once-a-month treatment to manage Cushing's disease," she says. While selective surgical removal of the tumor is the preferred treatment choice, the success rate in patients varies, and Cushing's symptoms persist in up to 35% of patients after surgery. In addition, recurrent rates (ie, return of disease) range from 13% to 66% after individuals experience different durations remaining in remission.1 Therefore, the availability of an effective, long-lasting drug will change the course of therapy for many patients with Cushing’s disease going forward. Not only will pasireotide benefit patients who have persistent and recurrent disease after undergoing surgery, but also this medication will be beneficial for those who are not candidates for surgery or just wish to avoid having this procedure, he said. Examining the Safety and Tolerability of Pasireotide This long-acting therapy, pasireotide, which is given by injection, was approved in the US after reviewing results of a 12-month Phase 3 trial.1 In the initial study, participants had a confirmed pituitary cause of the Cushing's disease. After that, the researchers added the optional 12-month open-label, extension study, and now patients can continue on in a separate long-term safety study. Those eligible for the 12-month extension had to have mean urinary free cortisol not exceeding the upper limit of normal (166.5 nanomoles per 24 hour) and/or be considered by the investigator to be getting substantial clinical benefit from treatment with long-action pasireotide, and to demonstrate tolerability of pasireotide during the core study.1 Of the 150 in the initial trial, 81 participants, or 54% of the patients, entered the extension study. Of those, 39 completed the next phase, and most also enrolled in another long-term safety study—these results not yet available).2 During the core study, 1 participants were randomly assigned to 10 or 30 mg of the drug every 28 days, with doses based on effectiveness and tolerability. When they entered the extension, patients were given the same dose they received at month.1,2 Study Outcomes Offer Advantages in Cushing’s Disease Of those who received 36 months of treatment with pasireotide, nearly three in four (72.2%) had controlled levels of urinary free cortisol at this time point.2 Equally good news for this drug was that tumors either shrank or did not grow. Of those individuals who started the trial with a measurable tumor (adenoma) as well as those with an adenoma at the two year mark (35 people), 85.7% of them experienced a reduction of 20% or more or less than a 20% change in tumor volume. No macroadenomas present at the start of the study showed a change of more than 20% at either month 24 or 36.2 Improvements in blood pressure, body mass index (BMI) and waist circumference continued throughout the extension study.1 Those factors influence CVD risk, the leading cause of death in those with Cushing's.4 As for adverse events, most of the study participants, 91.4%, did report one or more complaint during the extension study—most commonly, it was high blood sugar, which was reported by nearly 40% of participants.2. This is not surprising when you consider that most (81.5%) of the individuals participating in the extension trial entered with a diagnosis of diabetes or use of antidiabetic medication, and even more of them (88.9%) had diabetes at the last evaluation.1 This complication indicates the need for people with Cushing’s disease to check their blood glucose, as appropriate. Do You Have Cushing’s Disese? Here's What You Need to Know Women typically develop Cushing’s disease more often than men. What else should you be aware of if you and your doctor decide this medication will help you? Monitoring is crucial, says Dr. Fleseriu, as you will need to have your cortisol levels checked, and you should be on alert for any diabetes signals, which will require close monitoring and regular follow-up for disease management. Another understanding gained from the results of this drug study: "This medication works on the tumor level," she says. "If the patient has a macroadenoma (large tumor), this would be the preferred treatment." However, it should be used with caution in those with diabetes given the increased risk of experiencing high blood sugar. The researchers conclude that "the long-term safety profile of pasireotide was very favorable and consistent with that reported during the first 12 months of treatment. These data support the use of long-acting pasireotide as an effective long-term treatment option for some patients with Cushing's Disease."1 Understanding Benefits of New Drug to Treat Cushing's Diseease Vivien S. Herman-Bonert, MD, an endocrinologist and clinical director of the Pituitary Center at Cedars-Sinai Medical Center in Los Angeles, agreed to discuss the study findings, after agreeing to review the research for EndocrineWeb. As to who might benefit most from monthly pasireotide injections? Dr. Herman-Bonert says, "any patient with Cushing's disease that requires long-term medical therapy, which includes patients with persistent or recurrent disease after surgery." Certainly, anyone who has had poor response to any other medical therapies for Cushing's disease either because they didn't work well enough or because the side effects were too much, will likely benefit a well, she adds. Among the pluses that came out of the study, she says, is that nearly half of the patients had controlled average urinary free cortisol levels after two full years, and 72% of the participants who continued on with the drug for 36 months were able to remain in good urinary cortisol control .1 As the authors stated, tumor shrinkage was another clear benefit of taking long-term pasireotide. That makes the drug a potentially good choice for those even with large tumors or with progressive tumor growth, she says. It’s always good for anyone with Cushing’s disease to have an alterative to surgery, or a back-up option when surgery isn’t quite enough, says Dr. Herman-Bonert. The best news for patients is that quality of life scores improved,1 she adds. Dr Herman-Bonert did add a note of caution: Although the treatment in this study is described as ''long-term, patients will need to be on this for far longer than 2 to 3 years," she says. So, the data reported in this study may or may not persist, and we don’t yet know what the impact will be 10 or 25 years out. Also, the issue of hyperglycemia-related adverse events raises a concern, given the vast majority (81%) of patients who have both Cushing’s disease and diabetes. Most of those taking this drug had a dual diagnosis—having diabetes, a history of diabetes, or taking antidiabetic medicine. If you are under care for diabetes and you require treatment for Cushing’s disease, you must be ver mindful that taking pasireotide will likely lead to high blood sugar spikes, so you should plan to address this with your healthcare provider.

  25. In patients with Cushing’s disease, removing the pituitary tumor via an endoscopic transsphenoidal surgery (TSS) leads to better remission rates than microscopic TSS, according to new research. But regardless of surgical approach, plasma cortisol levels one day after surgery are predictive of remission, researchers found. The study, “Management of Cushing’s disease: Changing trend from microscopic to endoscopic surgery,” was published in the journal World Neurosurgery. Because it improves visualization and accessibility, endoscopic TSS has been gaining popularity over microscopic TSS to remove pituitary tumors in Cushing’s disease patients. Yet, although this surgery has been associated with high remission rates, whether it outperforms microscopic surgery and determining the factors affecting long-term outcomes may further ease disease recurrence after TSS. A team with the All India Institute of Medical Sciences addressed this topic in 104 patients who underwent surgery from January 2009 to June 2017. Among these patients, 47 underwent microscopic surgery and 55 endoscopic surgery. At presentation, their ages ranged from 9 to 55 (mean age of 28). Also, patients had been experiencing Cushing’s symptoms over a mean duration of 24 months. Eighty-seven patients showed weight gain. Hypertension (high blood pressure) and diabetes mellitus were among the most common co-morbidities, found in 76 and 33 patients, respectively. Nineteen patients had osteoporosis and 12 osteopenia, which refers to lower-than-normal bone mineral density. As assessed with magnetic resonance imaging, 68 patients had a microadenoma (a tumor diameter smaller than one centimeter) and 27 had a macroadenoma (a tumor one centimeter or larger). Only two patients had an invasive pituitary adenoma. Two patients with larger tumors were operated on transcranially (through the skull). The surgery resulted in total tumor removal in 90 cases (86.5%). A blood loss greater than 100 milliliter was more common with endoscopic than with microscopic TSS. Ten patients developed transient diabetes inspidus, two experienced seizures after surgery, and six of nine patients with macroadenoma and visual deterioration experienced vision improvements after TSS. The incidence of intraoperative leak of cerebrospinal fluid — the liquid surrounding the brain and spinal cord — was 23.2%, while that of post-operative leak was 7.7% and was more common in microadenoma than macroadenoma surgery (9.8% vs. 5.0%). Seventeen patients were lost to follow-up and two died due to metabolic complications and infections. The average follow-up was shorter for endoscopic than with microscopic surgery (18 months vs. 35 months). Among the remaining 85 cases, 65 (76.5%) experienced remission, as defined by a morning cortisol level under 5.0 μg/dL, restored circadian rhythm (the body’s internal clock, typically impaired in Cushing’s patients), and suppression of serum cortisol to below 2 μg/dl after overnight dexamethasone suppression test. The remission rate was 54.5% in pediatric patients and was higher with endoscopic than with microscopic TSS (88.2% vs. 56.6%). Also, patients with microadenoma showed a trend toward more frequent remission than those with macroadenoma (73.2% vs. 64.3%). Ten of the remaining 20 patients experienced disease recurrence up to 28 months after surgery. Sixteen cases revealed signs of hypopituitarism, or pituitary insufficiency, which were managed with replacement therapy. A subsequent analysis found that morning cortisol level on day one after surgery was the only significant predictor of remission. Specifically, a one-unit increase in cortisol lowered the likelihood of remission by 7%. A cortisol level lower than 10.7 μgm/dl was calculated as predicting remission. Overall, the study showed that “postoperative plasma cortisol level is a strong independent predictor of remission,” the researchers wrote, and that “remission provided by endoscopy is significantly better than microscopic approach.” From https://cushingsdiseasenews.com/2019/09/24/cortisol-levels-predict-remission-cushings-patients-undergoing-transsphenoidal-surgery/

So do we need to get our bones checked too? https://www.sciencealert.com/our-bones-provide-our-bodies-with-a-secret-weapon-that-saves-us-in-times-of-danger Bizarre Discovery Shows Your Bones Could Be Triggering The 'Fight-or-Flight' Response MIKE MCRAE 13 SEP 2019 When faced with a threat, hormones flood our bodies in preparation either for battle or a quick escape - what's commonly known as the 'fight-or-flight' response. For decades, we've generally thought this response was driven by hormones such as adrenaline. But it now seems that one of the most important of these messengers could come from a rather unexpected place – our skeleton. We usually think of chemicals like cortisol and adrenaline as the things that get the heart racing and muscles pumping. But the real star player could actually be osteocalcin, a calcium-binding protein produced by our bones. As a response to acute stress, steroids of the glucocorticoid variety are released by the body's endocrine system, where they manage the production of a cascade of other 'get ready to rumble' chemicals throughout various tissues. Researchers from the US, the UK, and India argue there's one tiny problem with this explanation of the fight-or-flight reaction. It isn't exactly fast. While nobody is disputing that our bodies produce cortisol when stressed, the fact their main action is to trigger cells into transcribing specific genes – a process that takes time – makes it an unlikely candidate for a rapid physiological response. "Although this certainly does not rule out that glucocorticoid hormones may be implicated in some capacity in the acute stress response, it suggests the possibility that other hormones, possibly peptide ones, could be involved," says geneticist Gerard Karsenty of Columbia University. So Karsenty and colleagues went on the hunt for something a little more expedient, focussing on proteins released by bone cells that would potentially have a more immediate effect on animal metabolism. Looking to the skeleton as a source might not be as weird as it first seems. After all, our bones evolved as a way to protect our squishy bits from being squashed, either by predator or accident. "If you think of bone as something that evolved to protect the organism from danger – the skull protects the brain from trauma, the skeleton allows vertebrates to escape predators, and even the bones in the ear alert us to approaching danger – the hormonal functions of osteocalcin begin to make sense," says Karsenty. Osteocalcin isn't in any way new to science, either. We've understood its function in bone development for nearly half a century, and in recent years begun to suspect it also has a hand in regulating our energy levels by affecting glucose metabolism. It also seems to give an ageing memory a boost, at least in lab rodents. All useful things in moments of danger. But it's still a surprising discovery that osteocalcin might also help to kickstart our acute stress response. "It completely changes how we think about how acute stress responses occur," says Karsenty. To test their suspicions, the researchers put lab mice under duress by restraining them for a 45 minute period. During that time, osteocalcin levels in the peripheral blood rose by half, while other skeletal hormones barely budged. In another test, just 15 minutes after a few harmless (but uncomfortable) shocks to the feet, osteocalcin levels in the stressed mice jumped by a whole 150 percent. Giving the test subjects a whiff of a chemical found in fox urine also elevated their peripheral osteocalcin levels. Importantly, these went up before their corticosterone levels began to climb, starting a few minutes after exposure and remaining high for another three hours. Just to make sure it wasn't only a mouse thing, the team also checked the hormone in humans who volunteered to do a public speech and undergo a pulse-raising cross-examination. Sure enough, up the osteocalcin went. In yet another series of tests, the team used rodents that were genetically engineered to lack the usual corticosteroid and other stress hormones, and found these animals continued to present a stress response. In addition, a shot of osteocalcin in otherwise unstressed mice was all they needed to get twitchy, raising their heart rate, temperature, and levels of circulating glucose. "Osteocalcin could explain past observations of an intact flight-or-flight response in humans and other animals lacking glucocorticoids and additional molecules produced by the adrenal glands," says Karsenty. With the evidence building for the bone protein as such a strong motivator for dealing with stress, it stands to ask why we need hormones like cortisol at all. The researchers plan to unravel this mystery in future investigations. This research was published in Cell Metabolism.
