Abstract

Corticotroph macroadenomas are rare but difficult to manage intracranial neoplasms. Mutations in the two Cushing’s disease mutational hotspots USP8 and USP48 are less frequent in corticotroph macroadenomas and invasive tumors. There is evidence that TP53 mutations are not as rare as previously thought in these tumors. The aim of this study was to determine the prevalence of TP53 mutations in corticotroph tumors, with emphasis on macroadenomas, and their possible association with clinical and tumor characteristics. To this end, the entire TP53 coding region was sequenced in 86 functional corticotroph tumors (61 USP8 wild type; 66 macroadenomas) and the clinical characteristics of patients with TP53 mutant tumors were compared with TP53/USP8 wild type and USP8 mutant tumors. We found pathogenic TP53 variants in 9 corticotroph tumors (all macroadenomas and USP8 wild type). TP53 mutant tumors represented 14% of all functional corticotroph macroadenomas and 24% of all invasive tumors, were significantly larger and invasive, and had higher Ki67 indices and Knosp grades compared to wild type tumors. Patients with TP53 mutant tumors had undergone more therapeutic interventions, including radiation and bilateral adrenalectomy. In conclusion, pathogenic TP53 variants are more frequent than expected, representing a relevant amount of functional corticotroph macroadenomas and invasive tumors. TP53 mutations associated with more aggressive tumor features and difficult to manage disease.

Patients with suspected adrenocortical carcinoma (ACC) may also undergo additional tests to identify excess sex steroids and steroid precursors, mineralocorticoids and glucocorticoids.

More than 80% of adults with Cushing’s disease receiving osilodrostat had normalized mean urinary free cortisol levels at 72 weeks of treatment, according to findings from the LINC 3 study extension.

“Cushing’s disease is a chronic condition, and many patients require prolonged pharmacological treatment. Therefore, evaluating long-term efficacy and safety of drug therapies in clinical trials is essential,” Maria Fleseriu, MD, FACE, professor of medicine and neurological surgery and director of the Pituitary Center at Oregon Health & Science University in Portland and a Healio | Endocrine Today co-editor, told Healio. “Our findings build on the positive results of the LINC 3 study core phase, and it was reassuring to see that continued treatment with osilodrostat for over 72 weeks provided long-term normalization of cortisol levels. Furthermore, continued treatment with osilodrostat also led to sustained improvements in clinical signs and physical manifestations of hypercortisolism, as well as health-related quality of life, which are all important factors in the management of these patients.”

Fleseriu and colleagues enrolled 106 adults with Cushing’s disease who were responders to osilodrostat (Isturisa, Recordati) at 48 weeks during the LINC 3 core study to enter the extension phase of the trial. Participants continued to receive open-label osilodrostat until 72 weeks or treatment discontinuation. Mean urinary free cortisol was collected every 12 weeks. Physical manifestations of hypercortisolism were rated at 48 and 72 weeks. Participants completed the Cushing’s Quality of Life questionnaire and Beck Depression Inventory II at 48 and 72 weeks. Adults were deemed to have completely responded to treatment if mean urinary free cortisol was less than the upper limit of normal and partially responded to treatment if mean urinary free cortisol was above the upper limit of normal but decreased more than 50% from baseline.

Pseudo-Cushing’s syndrome is when symptoms are similar to those of Cushing’s syndrome, but further tests show that the syndrome is not present.

Common causes include consuming too much alcohol, obesity, persistently high blood glucose levels, pregnancy, and depression.

 

Cortisol isn’t bad; you need it to help regulate your responses to life. Regulation involves a very complex interplay of feedback loops between the hypothalamus, pituitary gland, and adrenal glands, says Dr. Singh.

“In general, cortisol levels tend to peak in the late morning and gradually decline throughout the day,” he explains. “When a stressful event occurs, the increased cortisol will work alongside our ‘fight or flight’ mechanisms to either upregulate or downregulate bodily functions. [Affected systems include] the central nervous system, cardiovascular system, gastrointestinal system, or immune system.”

In addition to normal processes that trigger or suppress cortisol release, levels can also be affected by different medical conditions, Dr. Singh says. For example, if someone has abnormally high levels of cortisol, this is called Cushing’s syndrome, which is typically caused by a tumor affecting any of the glands that take part in the process of cortisol production.

When people suffer from abnormally low levels of cortisol, it’s called Addison’s disease. It generally occurs due to adrenal gland dysfunction, but could also be the result of abnormal functioning of any of the other glands in the cortisol production process.

Finally, if you use corticosteroid medications such as prednisone or dexamethasone, prolonged use will result in excessive cortisol production, Dr. Singh says.

“If the medication is not adequately tapered down when discontinued, the body’s ability to create cortisol can become permanently impaired,” he says.

Abstract

Background

Cushing’s syndrome (CS) is a rare condition of chronically elevated cortisol levels resulting in diverse comorbidities, many of which endure beyond successful treatment affecting the quality of life. Few data are available concerning patients’ experiences of diagnosis, care and persistent comorbidities.

Objective

To assess CS patients’ perspectives on the diagnostic and care journey to identify unmet therapeutic needs.

Methods

A 12-item questionnaire was circulated in 2019 by the World Association for Pituitary Organisations. A parallel, 13-item questionnaire assessing physician perceptions on CS patient experiences was performed.

Results

Three hundred twenty CS patients from 30 countries completed the questionnaire; 54% were aged 35–54 and 88% were female; 41% were in disease remission. The most burdensome symptom was obesity/weight gain (75%). For 49% of patients, time to diagnosis was over 2 years. Following treatment, 88.4% of patients reported ongoing symptoms including, fatigue (66.3%), muscle weakness (48.8%) and obesity/weight gain (41.9%). Comparisons with delay in diagnosis were significant for weight gain (P = 0.008) and decreased libido (P = 0.03). Forty physicians completed the parallel questionnaire which showed that generally, physicians poorly estimated the prevalence of comorbidities, particularly initial and persistent cognitive impairment. Only a minority of persistent comorbidities (occurrence in 1.3–66.3%; specialist treatment in 1.3–29.4%) were managed by specialists other than endocrinologists. 63% of patients were satisfied with treatment.

Conclusion

This study confirms the delay in diagnosing CS. The high prevalence of persistent comorbidities following remission and differences in perceptions of health between patients and physicians highlight a probable deficiency in effective multidisciplinary management for CS comorbidities.

Abstract

Background. Cushing’s disease (CD) recurrence in pregnancy is thought to be associated with estradiol fluctuations during gestation. CD recurrence in the immediate postpartum period in a patient with a documented dormant disease during pregnancy has never been reported. Case Report. A 30-year-old woman with CD had improvement of her symptoms after transsphenoidal resection (TSA) of her pituitary lesion. She conceived unexpectedly 3 months postsurgery and had no symptoms or biochemical evidence of recurrence during pregnancy. After delivering a healthy boy, she developed CD 4 weeks postpartum and underwent a repeat TSA. Despite repeat TSA, she continued to have elevated cortisol levels that were not well controlled with medical management. She eventually had a bilateral adrenalectomy. Discussion. CD recurrence may be higher in the peripartum period, but the link between pregnancy and CD recurrence and/or persistence is not well studied. Potential mechanisms of CD recurrence in the postpartum period are discussed below. Conclusion. We describe the first report of recurrent CD that was quiescent during pregnancy and diagnosed in the immediate postpartum period. Understanding the risk and mechanisms of CD recurrence in pregnancy allows us to counsel these otherwise healthy, reproductive-age women in the context of additional family planning.

Abstract: Ectopic pituitary adenoma (EPA) is a pituitary adenoma unrelated to the intrasellar component and is an extremely rare disease. EPA resembles typical pituitary adenomas in morphology, immunohistochemistry, and hormonal activity, and it may present with specific or non-specific endocrine manifestations. Here, we report a rare case of ectopic adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma in the clival region. Only three patients with ACTH-secreting pituitary adenomas occurring in the clivus have been previously reported, and the present case was diagnosed as a clivus-ectopic ACTH-secreting pituitary macroadenoma. Thus, in addition to the more common organs, such as the lung, thymus, and pancreas, in the diagnosis of ectopic ACTH syndrome, special attention should be paid to the extremely rare ectopic ACTH-secreting pituitary adenoma of the clivus region.

Abstract

MiRNAs are important epigenetic players with tissue- and disease-specific effects. In this study, our aim was to investigate the putative differential expression of miRNAs in adrenal tissues from different forms of Cushing’s syndrome (CS). For this, miRNA-based next-generation sequencing was performed in adrenal tissues taken from patients with ACTH-independent cortisol-producing adrenocortical adenomas (CPA), from patients with ACTH-dependent pituitary Cushing’s disease (CD) after bilateral adrenalectomy, and from control subjects. A confirmatory QPCR was also performed in adrenals from patients with other CS subtypes, such as primary bilateral macronodular hyperplasia and ectopic CS. Sequencing revealed significant differences in the miRNA profiles of CD and CPA. QPCR revealed the upregulated expression of miR-1247-5p in CPA and PBMAH (log2 fold change > 2.5, p < 0.05). MiR-379-5p was found to be upregulated in PBMAH and CD (log2 fold change > 1.8, p < 0.05). Analyses of miR-1247-5p and miR-379-5p expression in the adrenals of mice which had been exposed to short-term ACTH stimulation showed no influence on the adrenal miRNA expression profiles. For miRNA-specific target prediction, RNA-seq data from the adrenals of CPA, PBMAH, and control samples were analyzed with different bioinformatic platforms. The analyses revealed that both miR-1247-5p and miR-379-5p target specific genes in the WNT signaling pathway. In conclusion, this study identified distinct adrenal miRNAs as being associated with CS subtypes.

From my email - I know high blood pressure is quite common with Cushing’s but has anyone who has been diagnosed experienced very low blood pressure?

 

Introduction: Pasireotide (PAS) is a novel somatostatin receptor ligands (SRL), used in controlling hormonal hypersecretion in both acromegaly and Cushing’s Disease (CD). In previous studies and meta-analysis, first-generation SRLs were reported to be able to induce significant tumor shrinkage only in somatotroph adenomas. This systematic review and meta-analysis aim to summarize the effect of PAS on the shrinkage of the pituitary adenomas in patients with acromegaly or CD.

Materials and methods: We searched the Medline database for original studies in patients with acromegaly or CD receiving PAS as monotherapy, that assessed the proportion of significant tumor shrinkage in their series. After data extraction and analysis, a random-effect model was used to estimate pooled effects. Quality assessment was performed with a modified Joanna Briggs’s Institute tool and the risk of publication bias was addressed through Egger’s regression and the three-parameter selection model.

Results: The electronic search identified 179 and 122 articles respectively for acromegaly and CD. After study selection, six studies considering patients with acromegaly and three with CD fulfilled the eligibility criteria. Overall, 37.7% (95%CI: [18.7%; 61.5%]) of acromegalic patients and 41.2% (95%CI: [22.9%; 62.3%]) of CD patients achieved significant tumor shrinkage. We identified high heterogeneity, especially in acromegaly (I2 of 90% for acromegaly and 47% for CD), according to the low number of studies included.

Discussion: PAS treatment is effective in reducing tumor size, especially in acromegalic patients. This result strengthens the role of PAS treatment in pituitary adenomas, particularly in those with an invasive behavior, with progressive growth and/or extrasellar extension, with a low likelihood of surgical gross-total removal, or with large postoperative residual tissue.

Abstract

Although human cultures stimulated with dexamethasone suggest that the glucocorticoid receptor (GR) activates stress erythropoiesis, the effects of GR activation on erythropoiesis in vivo remains poorly understood.

We characterized the phenotype of a large cohort of patients with Cushing’s Disease, a rare condition associated with elevated cortisol levels. Results from hypercortisolemic patients with active Cushing’s were compared with those obtained from eucortisolemic patients after remission and from non-diseased volunteers. Active Cushing’s patients exhibit erythrocytosis associated with normal hemoglobin F levels. In addition, their blood contained elevated numbers of the GR-induced CD163+ monocytes and a unique class of CD34+ cells expressing CD110, CD36, CD133 and the GR-target gene CXCR4.

When cultured, these CD34+ cells generated similarly large numbers of immature erythroid cells in the presence and absence of dexamethasone, with raised expression of the GR-target gene GILZ. Of interest, blood from Cushing’s patients in remission maintained high numbers of CD163+ monocytes and, although their CD34+ cells had a normal phenotype, these cells were unresponsive to added dexamethasone.

Collectively, these results indicate that chronic exposure to excess glucocorticoids in vivo leads to erythrocytosis by generating erythroid progenitor cells with a constitutively active GR.

Although remission rescues the erythrocytosis and the phenotype of the circulating CD34+ cells, a memory of other prior changes is maintained in remission.

Introduction: Patients with Cushing’s syndrome (CS) represent a highly sensitive group during corona virus disease 2019 (COVID-19) pandemic. The effect of multiple comorbidities and immune system supression make the clinical picture complicated and treatment challenging.

Case report: A 70-year-old female was admitted to a covid hospital with a severe form of COVID-19 pneumonia that required oxygen supplementation. Prior to her admission to the hospital she was diagnosed with adrenocorticotropic hormone (ACTH)-dependent CS, and the treatment of hypercortisolism had not been started yet. Since the patient’s condition was quickly deteriorating, and with presumend immmune system supression due to CS, we decided on treatement with intraveonus immunoglobulins (IVIg) that enabled quick onset of immunomodulatory effect. All comorbidities were treated with standard of care. The patient’s condition quickly stabilized with no direct side effects of a given treatment.

Conclusion: Treatment of COVID-19 in patients with CS faces many challenges due to the complexity of comorbidity effects, immunosupression and potential interactions of available medications both for treatment of COVID-19 and CS. So far, there are no guidelines for treatment of COVID-19 in patients with active CS. It is our opinion that immunomodulating therapies like IVIg might be an effective and safe treatment modality in this particularly fragile group of patients.

Abstract

Cushing's syndrome (CS) shows diverse signs such as centripetal obesity, moon face, and buffalo hump, which can complicate the diagnosis. Facial features including eyelid edema, as an underrecognized sign, can be diagnostic clues for an excess of corticoids in a CS patient.

 



A 49-year-old woman presented with amenorrhea and weight gain that had continued for 2 years. Her medical history was dyslipidemia, hypertension, and osteoporosis. Physical examination revealed eyelid edemas (Figure 1A), moon face, buffalo hump, abdominal purple striae, and centripetal obesity (body mass index (BMI), 30.8 kg/m2). Basal plasma adrenocorticotropin was undetectable and serum cortisol level was high (16.9 μg/dl) without circadian rhythms. Free cortisol level in a 24-h urine collection was elevated (158.7 μg/day). Overnight administration of dexamethasone (1 mg) did not reduce serum cortisol level (17.4 μg/dl). Magnetic resonance imaging suggested bilateral adenomas. We made a diagnosis of adrenal Cushing's syndrome (CS). Since 131l-adosterol scintigraphy showed specific uptake in the left adrenal gland, left adrenalectomy was laparoscopically performed. Histopathology of the tumor was compatible with adrenocortical adenoma. Three months after surgery, her BMI decreased to 25.0 kg/m2 and eyelid edemas were ameliorated (Figure 1B).

(A) Bilateral eyelid edemas due to Cushing's syndrome are shown. (B) These findings were improved three months after surgery for left adrenal adenomas



Eyelid edema, in addition to centripetal obesity, moon face, and buffalo hump, is also a significant sign of CS; however, it has scarcely been reported in countries other than Japan.1, 2 Increased capillary permeability, insufficient venous return due to muscle atrophy, and sodium retention due to mineralocorticoid actions conceivably cause edema in CS.

Background

Cushing’s disease (CD) is among the most common etiologies of hypercortisolism. Magnetic resonance imaging (MRI) is often utilized in the diagnosis of CD, however, up to 64% of adrenocorticotropic hormone (ACTH)-producing pituitary microadenomas are undetectable on MRI. We report 15 cases of MRI negative CD who underwent surgical resection utilizing a purely endoscopic endonasal approach.

Methods

Endoscopic endonasal transsphenoidal surgery (EETS) was performed on 134 CD cases by a single surgeon. Fifteen cases met inclusion criteria: no conclusive MRI studies and no previous surgical treatment. Data collected included signs/symptoms, pre- and post-operative hormone levels, and complications resulting from surgical or medical management. Data regarding tumor diameter, location, and tumor residue/recurrence was obtained from both pre- and post-operative MRI. Immunohistochemistry was performed to assess for tumor hormone secretion.

Results

Aside from a statistically significant difference (P = 0.001) in histopathological results between patients with negative and positive MRI, there were no statistically significant difference between these two groups in any other demographic or clinical data point. Inferior petrosal sinus sampling (IPSS) with desmopressin (DDAVP®) administration was performed on the 15 patients with inconclusive MRIs to identify the origin of ACTH hypersecretion via a central/peripheral (C/P) ratio. IPSS in seven, five and three patients showed right, left, and central side lateralization, respectively. With a mean follow-up of 5.5 years, among MRI-negative patients, 14 (93%) and 12 patients (80%) achieved early and long-term remission, respectively. In the MRI-positive cohort, over a mean follow-up of 4.8 years, 113 patients (94.9%) and 102 patients (85.7%) achieved initial and long-term remission, respectively.

Conclusions

Abstract

Background

Cushing’s disease (CD) is rare in pediatric patients. It is characterized by elevated plasma adrenocorticotropic hormone (ACTH) from pituitary adenomas, with damage to multiple systems and development. In recent years, genetic studies have shed light on the etiology and several mutations have been identified in patients with CD.

Case presentation

A girl presented at the age of 10 years and 9 months with facial plethora, hirsutism and acne. Her vision and eye movements were impaired. A quick weight gain and slow growth were also observed. Physical examination revealed central obesity, moon face, buffalo hump, supra-clavicular fat pads and bruising. Her plasma ACTH level ranged between 118 and 151 pg/ml, and sella enhanced MRI showed a giant pituitary tumor of 51.8 × 29.3 × 14.0 mm. Transsphenoidal pituitary debulk adenomectomy was performed and immunohistochemical staining confirmed an ACTH-secreting adenoma. Genetic analysis identified a novel germline GPR101 (p.G169R) and a somatic USP8 (p. S719del) mutation. They were hypothesized to impact tumor growth and function, respectively.

Recordati Rare Diseases, a US biopharma that forms part of the wider Italian group, has presented multiple positive data sets on Isturisa (osilodrostat) at the annual ENDO 2022 meeting in Atlanta, Georgia.

Isturisa is a cortisol synthesis inhibitor indicated for the treatment of adult patients with Cushing’s disease for whom pituitary surgery is not an option or has not been curative.

Among the data presented, the Phase III LINC 4 study demonstrated that Isturisa maintained normal mean urinary free cortisol long-term in patients with Cushing’s disease while the Phase III LINC 3 study found adrenal hormone levels changed during early treatment with the drug while stabilizing during long-term treatment.

The ILLUSTRATE study also showed patients treated with a prolonged titration interval tended to have greater persistence with therapy.

Mohamed Ladha, president and general manager for North America, Recordati Rare Diseases, said: “The data from these studies reinforces the efficacy and safety of Isturisa as a treatment for patients with Cushing’s disease.

“We are pleased to share these data with the endocrine community and are excited to provide patients with a much-needed step forward in the management of this rare, debilitating, and potentially life-threatening condition.”

Cushing’s disease is a rare, serious illness caused by a pituitary tumor that leads to overproduction of cortisol by the adrenal glands. Excess cortisol can contribute to an increased risk of morbidity and mortality. Treatment for the condition seeks to lower cortisol levels to a normal range.

Isturisa, which was approved by the US Food and Drug Administration in March 2020, works by inhibiting 11-beta-hydroxylase, an enzyme responsible for the final step of cortisol biosynthesis in the adrenal gland.

MaryO'Note:  I found this article very simplistic.  What do you think?



Imagine the heart-pounding rush of adrenaline you’d get while bungee jumping or zip lining — that’s what Angela Yawn felt all the time before receiving her diagnosis.

In a span of six years, the 49-year-old gained 52 kg (115 lbs) and suffered from joint swelling, headaches, skin redness and a racing heart.

“I would put my hand on my chest because it made me feel like that’s what I needed to do to hold my heart in,” Yawn, who lives in Griffin, U.S., told Today. “I noticed it during the day, but at night when I was trying to lie down and sleep, it was worse because I could do nothing but hear it beat, feel it thump.”

Yawn recalled being the most frustrated with the weight gain, as she’d put on 1 kg (2 lbs) a day while only eating 600 calories. “I was going crazy,” she said.

After dozens of doctors couldn’t piece together her seemingly unrelated symptoms, Yawn sought out the help of an endocrinologist in February 2021.

Blood tests and an MRI confirmed that Yawn had a tumour in her pituitary gland — a small, pea-sized organ at the base of the brain — that caused the gland to release excess adrenocorticotropic hormones. As a result, she became inundated with cortisol, a steroid the body releases in response to danger or stress. This combination of factors led to her diagnosis — Cushing’s disease.

Abstract



 

Cushing's disease causes numerous metabolic disorders, cognitive decline, and sarcopenia, leading to deterioration of the general health in older individuals. Cushing's disease can be treated with transsphenoidal surgery, but thus far, surgery has often been avoided in older patients. We herein report an older woman with Cushing's disease whose cognitive impairment and sarcopenia improved after transsphenoidal surgery. Although cognitive impairment and sarcopenia in most older patients show resistance to treatment, our case indicates that normalization of the cortisol level by transsphenoidal surgery can be effective in improving the cognitive impairment and muscle mass loss caused by Cushing's disease.

ATLANTA — In this video exclusive, Maria Fleseriu, MD, FACE, reviews the pituitary research presented at the annual meeting of the Endocrine Society in Atlanta.

Fleseriu is professor of medicine and neurological surgery and director of the Pituitary Center at Oregon Health & Science University in Portland. She is also an Healio | Endocrine Today Co-editor.

Among the hottest pituitary topics at the meeting, according to Fleseriu, were dilemmas in pituitary tumors and data for new drugs for Cushing’s syndrome and acromegaly.

Abstract

Cushing syndrome is a rare disease that rarely presents as acute psychosis. In this case, the patient presented with acute psychosis and agitation as the first manifestations of the disease which led to the admission of the patient to a psychiatry hospital for one month, as it was difficult to restrain her sufficiently for performing appropriate diagnostic tests due to disturbing behavior. She responded well to treatment with olanzapine and lorazepam to treat the patient’s agitation, and successfully complete her evaluation. Thereafter, she was diagnosed with a pituitary tumor and underwent pituitary lesion resection via a microscopic transsphenoidal as needed. Two months after surgery, her cortisol levels returned to baseline, and she became calmer and decreased the tensity of her psychosis; however, it was only five months after surgery that her psychotic symptoms and disturbed behavior ceased.

Dr. Friedman uses several medications to treat Cushing’s syndrome that are summarized in this table. Dr. Friedman especially recommends ketoconazole. An in-depth article on ketoconazole can be found on goodhormonehealth.com.

Abstract

Introduction

Stress-related brain disorders can be associated with glucocorticoid disturbance and hippocampal alteration. However, it remains largely unknown how cortisol affects the structure and function of hippocampus. Cushing's disease (CD) provides a unique “hyperexpression model” to explore the effects of excessive cortisol on hippocampus as well as the relation between these effects and neuropsychological deficits.

Methods

We acquired high-resolution T1-weighted and resting-state functional magnetic resonance imaging in 47 CD patients and 53 healthy controls. We obtained the volume and functional connectivity of the hippocampal rostral and caudal subregions in both groups. Relationships between hippocampal alterations, neuroendocrine, and neuropsychological assessments were identified.

Results

Relative to control subjects, the CD patients had smaller volumes of all four hippocampal subregions. Furthermore, whole brain resting-state functional connectivity analyses with these four different hippocampal regions as seeds revealed altered hippocampal functional connectivity with high-order networks, involving the DMN, frontoparietal, and limbic networks in CD patients. The intrinsic hippocampal functional connectivity was associated with the quality of life of the CD patients.

Conclusions

Our findings elucidate the cumulative effect of excess cortisol on the morphology and function of hippocampus and reinforce the need for effective interventions in stress-related brain disease to halt potential hippocampal damage.
