  1. Abstract Summary Here, we describe a case of a patient presenting with adrenocorticotrophic hormone-independent Cushing’s syndrome in a context of primary bilateral macronodular adrenocortical hyperplasia. While initial levels of cortisol were not very high, we could not manage to control hypercortisolism with ketoconazole monotherapy, and could not increase the dose due to side effects. The same result was observed with another steroidogenesis inhibitor, osilodrostat. The patient was finally successfully treated with a well-tolerated synergitic combination of ketoconazole and osilodrostat. We believe this case provides timely and original insights to physicians, who should be aware that this strategy could be considered for any patients with uncontrolled hypercortisolism and delayed or unsuccessful surgery, especially in the context of the COVID-19 pandemic. Learning points Ketoconazole–osilodrostat combination therapy appears to be a safe, efficient and well-tolerated strategy to supress cortisol levels in Cushing syndrome. Ketoconazole and osilodrostat appear to act in a synergistic manner. This strategy could be considered for any patient with uncontrolled hypercortisolism and delayed or unsuccessful surgery, especially in the context of the COVID-19 pandemic. Considering the current cost of newly-released drugs, such a strategy could lower the financial costs for patients and/or society. Keywords: Adult; Male; White; France; Adrenal; Adrenal; Novel treatment; December; 2021 Background Untreated or inadequately treated Cushing’s syndrome (CS) is a morbid condition leading to numerous complications. The latter ultimately results in an increased mortality that is mainly due to cardiovascular events and infections. The goal of the treatment with steroidogenesis inhibitors is normalization of cortisol production allowing the improvement of comorbidities (1). Most studies dealing with currently available steroidogenesis inhibitors used as monotherapy reported an overall antisecretory efficacy of roughly 50% in CS. Steroidogenesis inhibitors can be combined to better control hypercortisolism. To the best of our knowledge, we report here for the first time a patient treated with a ketoconazole–osilodrostat combination therapy. Case presentation Here, we report the case of Mr D.M., 53-years old, diagnosed with adrenocorticotrophic hormone (ACTH)-independent CS 6 months earlier. At diagnosis, he presented with resistant hypertension, hypokalemia, diabetes mellitus, easy bruising, purple abdominal striae and major oedema of the lower limbs. Investigations A biological assessment was performed, and the serum cortisol levels are depicted in Table 1. ACTH levels were suppressed (mean levels 1 pg/mL). Mean late-night salivary cortisol showed a four-fold increase (Table 2), and mean 24 h-urinary cortisol showed a two-fold increase. Serum cortisol was 1000 nmol/L at 08:00 h after 1 mg dexamethasone dose at 23:00 h. The rest of the adrenal hormonal workup was within normal ranges (aldosterone: 275 pmol/L and renin: 15 mIU/L). An adrenal CT was performed (Fig. 1) and exhibited a 70-mm left adrenal mass (spontaneous density: 5 HU and relative washout: 65%) and a 45-mm right adrenal mass (spontaneous density: −2 HU and relative washout: 75%). The case was discussed in a multidisciplinary team meeting, which advised to perform 18F-FDG PET-CT and 123I-Iodocholesterol scintigraphy before considering surgery. A genetic screening was performed, testing for ARMC5 and PRKAR1A pathogenic variants. View Full Size Figure 1 Adrenal CT depicting the bilateral macronodular adrenocortical hyperplasia.

Osilodrostat–ketoconazole combination 10 14 9 11 Treatment As this condition occurred during the COVID-19 pandemic, it was decided to first initiate steroidogenesis inhibitors to lower the patient’s cortisol levels. Initially, ketoconazole was initiated and uptitrated up to 1000 mg per day based on close serum cortisol monitoring, with a three-fold increase of liver enzymes and poor control of cortisol levels (Table 1). In the absence of biological efficacy, ketoconazole was replaced by osilodrostat, which was gradually increased up to 30 mg per day (10 mg at 08:00 h and 20 mg at 20:00 h) without reaching normal cortisol levels (Table 1) and with slightly increased blood pressure levels. Considering the lack of efficacy of anticortisolic drugs used as monotherapy, we combined osilodrostat (30 mg per day) to ketoconazole (600 mg per day), that is, at the last maximal tolerated dose as monotherapy of each drug. Outcome This combination of steroidogenesis inhibitors achieved a good control in cortisol levels, mimicking a physiological circadian rhythm (Table 1D). The patient did not exhibit any side effect and the control of cortisol levels resulted in a rapid improvement of hypertension, kalemia, diabetes control and disappearance of lower limbs oedema. The patient underwent a 18F-FDG PET-CT that did not exhibit any increased uptake in both adrenal masses and a 123I-Iodocholesterol scintigraphy exhibiting a highly increased uptake in both adrenal masses, predominating in the left adrenal mass (70 mm). Unilateral adrenalectomy of the larger mass was then performed, and as the immediate post-operative serum cortisol level was 50 nmol/L, hydrocortisone was administered at a dose of 30 mg per day, with a stepwise decrease to 10 mg per day over 3 months. Pathological examination exhibited macronodular adrenal hyperplasia with a 70-mm adreno cortical adenoma (WEISS score: 1 and Ki67: 1%). The genetic screening exhibited a c.1908del p.(Phe637Leufs*6) variant of ARMC5 (pathogenic), located in exon 5. The patient has no offspring and is no longer in contact with the rest of his family. Discussion The goal of the treatment with steroidogenesis inhibitors is normalization of cortisol production allowing the improvement of comorbidities (1). Most studies dealing with currently available steroidogenesis inhibitors used as monotherapy reported an overall antisecretory efficacy of roughly 50% in CS. This rate of efficacy was probably underestimated in retrospective studies due to the lack of adequate uptitration of the dose; For example, the median dose reported in the French retrospective study on ketoconazole was only 800 mg/day, while 50% of the patients were uncontrolled at the last follow-up (2). Steroidogenesis inhibitors can be combined to better control hypercortisolism. Up to now, such combinations, mainly ketoconazole and metyrapone, were mainly reported in patients with severe CS (median urinary-free Cortisol (UFC) 30- to 40-fold upper-limit norm (ULN)) and life-threatening comorbidities (3, 4). Normal UFC was reported in up to 86% of these patients treated with high doses of ketoconazole and metyrapone. Expected side effects (such as increased liver enzymes for ketoconazole or worsened hypertension and hypokalemia for metyrapone) were reported in the majority of the patients. The fear of these side effects probably explains the lack of uptitration in previous reports. Combination of steroidogenesis inhibitors has previously been described by Daniel et al. in the largest study reported on the use of metyrapone in CS; 29 patients were treated with metyrapone and ketoconazole or mitotane, including 22 in whom the second drug was added to metyrapone monotherapy because of partial efficacy or adverse effects. The final median metyrapone dose in patients controlled with combination therapy was 1500 mg per day (5). Combination of adrenal steroidogenesis inhibitors should not be reserved to patients with severe hypercortisolism. In the case shown here, the association was highly effective in terms of secretion, using lower doses than those applied as a single treatment, but without the side effects previously observed with higher doses of each treatment used as a monotherapy. To our knowledge, the association of ketoconazole and osilodrostat had never been reported. Ketoconazole blocks several enzymes of the adrenal steroidogenesis such as CYP11A1, CYP17, CYP11B2 (aldosterone synthase) and CYP11B1 (11-hydroxylase), leading to decreased cortisol and occasionally testosterone concentrations. Though liver enzymes increase is not dose-dependent, it usually happens at doses exceeding 400–600 mg per day (2). Osilodrostat blocks CYP11B1 and CYP11B2; a combination should thus allow for a complete blockade of these enzymes that are necessary for cortisol secretion. Short-term side effects such as hypokalemia and hypertension are similar to those observed with metyrapone, due to increased levels of the precursor deoxycorticosterone, correlated with the dose of osilodrostat (6). As for our patient, the occurrence of side effects should not lead to immediately switch to another drug, but rather to decrease the dose and add another cortisol-lowering drug. Moreover, considering the current cost of newly-released drugs such a strategy could lower financial costs for patients and/or society. Another point to take into account is the current COVID-19 pandemic, for which, as recently detailed in experts’ opinion (7), the main aim is to reach eucortisolism, whatever the way. Indeed patients presenting with CS usually also present with comorbidities such as obesity, hypertension, diabetes mellitus and immunodeficiency (8). Surgery, which represents the gold standard strategy in the management of CS (1, 9), might be delayed to reduce the hospital-associated risk of COVID-19, with post-surgical immunodepression and thromboembolic risks (7). Because immunosuppression and thromboembolic diathesis are common CS features (9, 10), during the COVID-19 pandemic, the use of steroidogenesis inhibitors appears of great interest. In these patients, combing steroidogenesis inhibitors at intermediate doses might allow for a rapid control of hypercortisolism without risks of major side effects if a single uptitrated treatment is not sufficient. Obviously, the management of associated comorbidities would also be crucial in this situation (11). To conclude, we report for the first time a case of CS, in the context of primary bilateral macronodular adrenocortical hyperplasia successfully treated with a well-tolerated combination of ketoconazole and osilodrostat. While initial levels of cortisol were not very high, we could not manage to control hypercortisolism with ketoconazole monotherapy, and could not increase the dose due to side effects. The same result was observed with another steroidogenesis inhibitor, osilodrostat. This strategy could be considered for any patient with uncontrolled hypercortisolism and delayed or unsuccessful surgery, especially in the context of the COVID-19 pandemic.

  2. J Clin Endocrinol Metab . 2003 Apr;88(4):1554-8. doi: 10.1210/jc.2002-021518. Francesca Pecori Giraldi 1, Mirella Moro, Francesco Cavagnini, Study Group on the Hypothalamo-Pituitary-Adrenal Axis of the Italian Society of Endocrinology Affiliations PMID: 12679438 DOI: 10.1210/jc.2002-021518 Abstract Cushing's disease (CD) presents a marked female preponderance, but whether this skewed gender distribution has any relevance to the presentation and outcome of CD is not known. The aim of the present study was the comparison of clinical features, biochemical indices of hypercortisolism, and surgical outcome among male and female patients with CD. The study population comprised 280 patients with CD (233 females, 47 males) collected by the Italian multicentre study. Epidemiological data, frequency of clinical signs and symptoms, urinary free cortisol (UFC), plasma ACTH and cortisol levels, responses to dynamic testing, and surgical outcome were compared in female and male patients. Male patients with CD presented at a younger age, compared with females (30.5 +/- 1.93 vs. 37.1 +/- 0.86 yr, P < 0.01), with higher UFC and ACTH levels (434.1 +/- 51.96 vs. 342.1 +/- 21.01% upper limit of the normal range for UFC, P < 0.05; 163.9 +/- 22.92 vs. 117.7 +/- 9.59% upper limit of the normal range for ACTH, P < 0.05). No difference in ACTH and cortisol responses to CRH, gradient at inferior petrosal sinus sampling, and cortisol inhibition after low-dose dexamethasone was recorded between sexes. In contrast, the sensitivity of the high-dose dexamethasone test was significantly lower in male than in female patients. Of particular interest, symptoms indicative of hypercatabolic state were more frequent in male patients; indeed, males presented a higher prevalence of osteoporosis, muscle wasting, striae, and nephrolitiasis. Conversely, no symptom was more frequent in female patients with CD. Patients with myopathy, hypokalemia, and purple striae presented significantly higher UFC levels, compared with patients without these symptoms. Lastly, in male patients, pituitary imaging was more frequently negative and immediate and late surgical outcome less favorable. In conclusion, CD appeared at a younger age and with a more severe clinical presentation in males, compared with females, together with more pronounced elevation of cortisol and ACTH levels. Furthermore, high-dose dexamethasone suppression test and pituitary imaging were less reliable in detecting the adenoma in male patients, further burdening the differential diagnosis with ectopic ACTH secretion. Lastly, the postsurgical course of the disease carried a worse prognosis in males. Altogether, these findings depict a different pattern for CD in males and females.
