ObjectiveThe objective of this systematic review was to evaluate the effectiveness and safety of pasireotide, cabergoline, ketoconazole, levoketoconazole, metyrapone, osilodrostat, and temozolomide for the treatment of Cushing’s disease (CD).MethodsThe primary outcomes were the proportion of CD control, adverse events (AE), and reduction of urinary free cortisol. Search strategies were applied to Embase, Medline, and CENTRAL. Independent reviewers assessed the study eligibility, extracted data, and evaluated risk of bias. Standardized mean difference was calculated with 95% confidence interval (CI) for continuous data (i.e., pre- and post-intervention). Random meta-analyses for the proportion of CD control and AE were conducted.ResultsTwenty-nine controlled and non-controlled studies were included. No study with temozolomide and levoketoconazole and one study with osilodrostat fulfilled the inclusion criteria. The meta-analyses of proportion of CD control was 35% for cabergoline (95% CI: 27–43%, six studies, 141 participants), 44% for pasireotide (95% CI: 25–35%, eight studies, 522 participants), 41% for ketoconazole (95% CI: 36–46%, six studies, 450 participants), 66% for metyrapone (95% CI: 46–87%, four studies, 66 participants), and of 66.4% for osilodrostat (95% CI: 57.9, 74.3, 97 participants, one study). One study compared two different treatments (cabergoline vs. ketoconazole), and no statistical difference was observed in CD control (RR: 0.53, 95% CI: 0.15 to 1.87, 14 participants, very low certainty of evidence). The most frequent AE associated with pasireotide was hyperglycemia, dizziness and nausea with cabergoline and metyrapone, and elevated transaminases with ketoconazole.ConclusionThe superiority of one drug over another could not be determined due to lack of controlled studies, but the proportion of disease control identified in our meta-analysis may support clinical decision. New therapeutic options should be investigated due to the limited efficacy and tolerability of the currently available medical treatment for patients with Cushing’s disease.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020205567, identifier CRD42020205567.

Abstract Introduction: During the 22-week core LINC 2 study, the oral 11β-hydroxylase inhibitor osilodrostat normalized mean urinary free cortisol (mUFC) in 79% (15/19) of patients with Cushing’s disease. This report describes long-term LINC 2 efficacy and safety results following an optional extension. Methods: Patients receiving clinical benefit at week 22 could enter the extension (that ran until Oct 22, 2019), continuing the same osilodrostat dose; dose adjustments were permitted based on efficacy and safety. Response rate (mUFC ≤ULN [controlled] or mUFC >ULN but ≥50% decrease from baseline [BL; partially controlled]) was assessed over time. Efficacy/safety were assessed for all patients from core BL until study end. Results: Of 19 enrolled patients (female:male 14:5; mean [SD] age 36.8 years [8.4]), 16 entered the optional extension and 8 of them remained on treatment until study end. Median (range) osilodrostat exposure was 282 weeks (2-351). Mean mUFC decreased from BL (9.9 x ULN) to ≤ULN by week 4 and remained stable throughout the study. All 19 patients achieved mUFC ≤ULN at least once during the study. At each assessment up to month 70 of the extension phase, 50-88% of ongoing patients were controlled, and up to 18% were partially controlled. Mean percentage change in clinical signs from BL (mean [SD]) to last assessment were: fasting plasma glucose, -10.8% (22.1) (from BL: 105.6 mg/dL [49.2]); HbA1c, -2.1% (9.0) (from BL: 5.7% [0.7]); systolic BP, -3.3% (12.6) (from BL: 132.6 mmHg [11.6]); diastolic BP, -2.0% (10.4) (from BL: 85.0 mmHg [6.5]); BMI, -5.9% (8.8) (from BL: 30.7 kg/m2 [7.0]). Overall, 9 patients discontinued treatment (n=2 core and n=7 extension), mostly because of AEs or no longer requiring treatment (n=3 each). The most common AEs during the entire treatment period were nausea (n=10), adrenal insufficiency, and headache (both n=9). AEs related to hypocortisolism and adrenal hormone precursor accumulation occurred in 11 (mostly adrenal insufficiency, n=9) and 12 patients (mostly hypertension, n=4), respectively; most were grade 1/2 and managed with dose adjustment/interruption and/or concomitant medication. Mean (SD) plasma ACTH increased from 1.8 x ULN (0.9) at BL to 7.1 x ULN (12.3) at week 22 and 6.9 x ULN (12.6) at last assessment. Mean (SD) 11-deoxycortisol increased from 1.2 x ULN (1.3) at BL to 13.6 x ULN (12.2) at week 22 and 3.6 x ULN (4.2) at last assessment. In females, mean (SD) testosterone increased from 0.8 x ULN (0.4) at BL to 2.4 x ULN (2.1) at week 22 and 1.0 x ULN (0.9) at last assessment. Two patients, both female, reported an AE of hirsutism. Conclusions: Rapid reductions in mUFC were sustained for up to 6 years of osilodrostat treatment and were accompanied by improvements in clinical signs of hypercortisolism. Osilodrostat was well tolerated, with no new safety signals during long-term treatment.

In this study we aimed to assess vitamin D metabolism in patients with Cushing’s disease (CD) compared to healthy individuals in the setting of bolus cholecalciferol treatment. The study group included 30 adults with active CD and the control group included 30 apparently healthy adults with similar age, sex and BMI. All participants received a single dose (150,000 IU) of cholecalciferol aqueous solution orally. Laboratory assessments including serum vitamin D metabolites (25(OH)D3, 25(OH)D2, 1,25(OH)2D3, 3-epi-25(OH)D3 and 24,25(OH)2D3), free 25(OH)D, vitamin D-binding protein (DBP) and parathyroid hormone (PTH) as well as serum and urine biochemical parameters were performed before the intake and on Days 1, 3 and 7 after the administration. All data were analyzed with non-parametric statistics. Patients with CD had similar to healthy controls 25(OH)D3 levels (p > 0.05) and higher 25(OH)D3/24,25(OH)2D3 ratios (p < 0.05) throughout the study. They also had lower baseline free 25(OH)D levels (p < 0.05) despite similar DBP levels (p > 0.05) and lower albumin levels (p < 0.05); 24-h urinary free cortisol showed significant correlation with baseline 25(OH)D3/24,25(OH)2D3 ratio (r = 0.36, p < 0.05). The increase in 25(OH)D3 after cholecalciferol intake was similar in obese and non-obese states and lacked correlation with BMI (p > 0.05) among patients with CD, as opposed to the control group. Overall, patients with CD have a consistently lower 25(OH)D3/24,25(OH)2D3 ratio, which is indicative of a decrease in 24-hydroxylase activity. This altered activity of the principal vitamin D catabolism might influence the effectiveness of cholecalciferol treatment. The observed difference in baseline free 25(OH)D levels is not entirely clear and requires further study.

Abstract Diagnosis of endogenous Cushing’s syndrome entails corticotropic autonomy, lack of circadian rhythm and/or hypercortisolism, evaluated through 24h urinary free cortisol (UFC). Hair cortisol measurement (HCM) has been described as an alternative marker of cortisol exposure over the preceding three months. OBJECTIVES To evaluate HCM in Cushing’s disease (CD). To analyze the correlation between HCM and UFC. To compare HCM values in CD vs controls. PATIENTS AND METHODS 3 cm hair from posterior vertex in CD and in controls age- and gender-matched between May 2017 and May 2019. Controls were low level stressed individuals (Holmes-Rahe’s scale) without adrenal disease. Normal reference interval of HCM was defined (40-128 pg/mg hair). Measurement: Siemens Immulite 2000 (Gwynedd, UK) automated chemoluminiscent immunoassay (CLIA) UFC values within the 3 months previous to hair collection were considered. Controlled CD defined as UFC ≤1 upper normal limit (UNL) with or without treatment, remission as UFC ≤1 without pituitary lesion. Results are presented as median (m) and range. Kruskal-Wallis ANOVA used for median difference evaluation and Kappa index for concordance determination. Chi2 test for comparison of recategorized UFC and HCM. Statistical analysis performed with SPSS 23.0 RESULTS 23 CD patients recruited, median age 42 ± 11 years; 91% (n=21) female; 10 samples collected at diagnosis and 13 during follow-up. Control group composed of 50 individuals 45% (n=10) had controlled CD (mUFC 0.42 UNL, range 0.1-0.9) and a mHCM of 134.5 pg/mg (62-334) and 55% (n=12) did not have control (mUFC 2.2, 1.1-6) and a mHCM of 150.5 (75-459). After recategorization of UFC (&gt; o ≤ 1 UNL) and HCM (&gt; o ≤ 128 pg/mg), determinations were associated (Chi2, p= 0.18), however, the concordance was acceptable (Kappa index = 0.276). After dividing CD patients according to HCM, 35% (n=8) had normal HCM: mHCM 113.5 (62-126) and mUFC 0.45 (0.1- 4.4). Among them, 63% (n=5) had controlled CD (mHCM 110, 62-121; mUFC 0.39, 0.1-0.85); 25% (n=2) had active CD (mUFC 2.7, 1.1-4.4; mHCM 121, 75-126). 65% had high HCM (n=15): mHCM 167 (132-459) and mUFC 1.36 (0.1-6). Most of them had active CD (n=11, 73%): mHCM 160 (132-459) and mUFC 2.2 (1.1-6). Four patients with elevated HCM (m 248, 148-334) had normal UFC (m 0.61, 0.12-0.92): 2 were in remission, 1 had normal postsurgical UFC with active disease in the follow-up and 1 had normal UFC under medical treatment. Controls (n=50) had mHCM 62.5 (40-126), significantly different from CD. CONCLUSIONS We evaluated HCM in CD, proposing this method as an additional diagnostic test for hypercortisolism. The acceptable concordance between UFC and HCM is possibly due to the different duration of the evaluated periods. The difference in the HCM values observed between controlled or active CD patients and controls permits the consideration of the method as an alternative in the diagnosis and/or follow-up of CD.

Objective Monitoring of patients with Cushing’s disease on cortisol-lowering drugs is usually performed with urinary free cortisol (UFC). Late-night salivary cortisol (LNSC) has an established role in screening for hypercortisolism and can help to detect the loss of cortisol circadian rhythm. Less evidence exists regarding the usefulness of LNSC in monitoring pharmacological response in Cushing’s disease. Design Exploratory analysis evaluating LNSC during a Phase III study of long-acting pasireotide in Cushing’s disease (clinicaltrials.gov: NCT01374906). Methods Mean LNSC (mLNSC) was calculated from two samples, collected on the same days as the first two of three 24-h urine samples (used to calculate mean UFC [mUFC]). Clinical signs of hypercortisolism were evaluated over time. Results At baseline, 137 patients had evaluable mLNSC measurements; 91.2% had mLNSC exceeding the upper limit of normal (ULN; 3.2 nmol/L). Of patients with evaluable assessments at month 12 (n = 92), 17.4% had both mLNSC ≤ULN and mUFC ≤ULN; 22.8% had mLNSC ≤ULN, and 45.7% had mUFC ≤ULN. There was high variability in LNSC (intra-patient coefficient of variation (CV): 49.4%) and UFC (intra-patient CV: 39.2%). mLNSC levels decreased over 12 months of treatment and paralleled changes in mUFC. Moderate correlation was seen between mLNSC and mUFC (Spearman’s correlation: ρ = 0.50 [all time points pooled]). Greater improvements in systolic/diastolic blood pressure and weight were seen in patients with both mLNSC ≤ULN and mUFC ≤ULN. Conclusion mUFC and mLNSC are complementary measurements for monitoring treatment response in Cushing’s disease, with better clinical outcomes seen for patients in whom both mUFC and mLNSC are controlled.

ObjectiveIn Cushing's disease (CD), GH responsiveness to several stimuli, including ghrelin, GHRP-6, and GHRH, is blunted. Recovery of GH secretion after remission of hypercortisolism after transsphenoidal surgery, radiotherapy, or adrenalectomy is controversial. There are no studies evaluating the effect of primary clinical treatment with ketoconazole on GH secretion in CD. The aim of this study is to compare ghrelin-, GHRP-6-, and GHRH-induced GH release before and after ketoconazole in CD.DesignGH responses to ghrelin, GHRP-6, and GHRH of eight untreated patients with CD (mean age: 33.8±3.1 years; body mass index: 28.5±0.8 kg/m2) were evaluated before and after 3 and 6 months of ketoconazole treatment, and compared with 11 controls (32.1±2.5; 25.0±0.8).MethodsSerum GH was measured by an immunofluorometric assay and urinary free cortisol (UFC) by liquid chromatography and tandem mass spectrometry.ResultsAfter ketoconazole use, mean UFC decreased significantly (before: 222.4±35.0 μg/24 h; third month: 61.6±10.1; sixth month: 39.1±10.9). Ghrelin-induced GH secretion increased significantly after 6 months (peak before: 6.8±2.3 μg/l; sixth month: 16.0±3.6), but remained lower than that of controls (54.1±11.2). GH release after GHRP-6 increased, although not significantly, while GH responsiveness to GHRH was unchanged.ConclusionsGhrelin-induced GH release increases significantly after 6 months of ketoconazole treatment in CD. This could suggest that a decrease in cortisol levels during this time period can partially restore glucocorticoid-induced GH suppression in CD. GH-releasing mechanisms stimulated by ghrelin/GHS could be more sensitive, as no changes in GHRH-induced GH release were observed.
