Abstract. Twenty-eight patients underwent transsphenoidal pituitary surgery for Cushing's disease. Selective surgical procedures were performed in 26. In 19 patients pituitary adenoma was confirmed histologically and 5 had clumps or clusters of ACTH-staining cells. At follow-up after 22.3 (range 5-56) months 21 (75%) patients remained in clinical and biochemical remission. The 24-h urinary free cortisol performed between 1 and 4 weeks postoperatively while patients took replacement doses of dexamethasone (0.5 to 0.75 mg per day) was found to predict outcome. All patients with suppressed urinary free cortisol excretion have remained in remission, 3 with levels in the normal range have suffered late relapse after initial remission, and 4 with elevated urinary free cortisol excretion were regarded as having failed to remit. Furthermore, all patients with unsuccessful outcomes had no pituitary adenoma and 3 had features consistent with corticotrope nodular hyperplasia at histological examination compared to only 2 and 1, respectively, of patients still in remission. We conclude that 24-h urinary free cortisol performed at 1 to 4 weeks postoperatively whilst on low-dose dexamethasone and the histological findings may predict outcome following transsphenoidal pituitary surgery in Cushing's disease.

ContextAlternatives to transsphenoidal pituitary surgery may be required in Cushing's disease (CD) as a first- or second-line treatment. Mitotane is a potent anti-cortisolic drug but has been rarely investigated in the treatment of CD.ObjectiveEvaluation of the efficacy and tolerance of mitotane in CD patients.Design and settingRetrospective analysis of 76 patients treated with mitotane from 219 patients diagnosed with CD between 1993 and 2009 in a single center.Main outcome measureRemission was defined as normalization of 24-h urinary free cortisol (24-h-UFC).ResultsRemission was achieved in 48 (72%) of the 67 long-term treated patients, after a median time of 6.7 (5.2–8.2) months. Mean plasma mitotane concentration at the time of remission was 10.5±8.9 mg/l, with a mean daily dose of 2.6±1.1 g. A negative linear relationship was observed between plasma mitotane concentration and 24-h-UFC (P<0.0001). Seventeen of 24 (71%) patients with durable remission subsequently experienced recurrence, after a median time of 13.2 (5.0–67.9) months. At the time of treatment discontinuation, ACTH concentration was statistically associated with a lower recurrence probability (hazard ratios 0.57 (0.32–1.00), P=0.05). Intolerance leading to treatment discontinuation occurred in 19 patients (29%). A pituitary adenoma became identifiable during mitotane treatment in 12 (25%) of the 48 patients with initial negative pituitary imaging allowing subsequent transsphenoidal surgery.ConclusionMitotane is useful at different stages of CD. Mitotane dose adjustment based on plasma concentration monitoring and side effects could control hypercortisolism in the majority of CD patients.

Abstract BACKGROUND: Cyclic Cushing’s disease is rare and treatments have not been established for post-surgical recurrent cases. Here, we report a patient with recurrent cyclic Cushing’s disease, whose subjective symptoms improved by administration of metyrapone and hydrocortisone. Clinical Case: A 45-year-old woman had exhibited face and peripheral edema, hyperphagia, weight gain, hair loss and limb numbness since September X-10. In May X-9, her ACTH and cortisol levels were high (87.8 pg/mL and 28.8 µg/dL, respectively), and she was referred to our department. A brain MRI revealed a pituitary adenoma of 7mm in diameter. Because blood ACTH and cortisol levels turned normal and typical Cushingoid features were absent at the admission to our department, cyclic Cushing’s disease was suspected. Later in September, because subjective symptoms recurred accompanied with blood cortisol level elevation, she was diagnosed as cyclic Cushing’s disease with the examinations including inferior petrosal sinus sampling. Transsphenoidal surgery was performed in November, and immunohistology confirmed ACTH-producing pituitary adenoma based on ACTH positivity. After the surgery, endocrine test results were normalized and subjective symptoms were ameliorated. In March X-3, the blood ACTH level increased again; however, no subjective symptoms were observed. From May X, she had experienced limb numbness, hyperphagia and weight gain again. MRI showed no apparent recurrence, but endocrine tests showed the activity of Cushing’s disease. Urinary free cortisol (UFC) increased to 300–400 µg/day in a 1-week cycle, indicating the recurrence of cyclic Cushing’s disease. Metyrapone treatment was initiated, and the patient was finally discharged after block and replace therapy with metyrapone 2,000 mg/day and hydrocortisone 15 mg/day. After metyrapone treatment, subjective symptoms improved and UFC was normalized. Conclusion: Block and replace therapy with metyrapone and hydrocortisone may be effective for recurrent cyclic Cushing’s disease, especially in cases with a very short cycle.

The remission rate of Cushing’s disease in patients after neurosurgery varies from 59 to 94%, while the recurrence rate is 3 to 46%. Aim — to evaluate the five-year outcome in neurosurgery patients with Cushing’s disease (CD), depending on preoperative MRI-based identification of pituitary adenoma. Material and methods. The study included 105 neurosurgery patients with histologically confirmed CD. CD remission was confirmed by the development of adrenal insufficiency and/or normalization of serum cortisol and 24-hour urinary free cortisol (24h UFC) levels, as well as by clinical remission. Results. Pituitary adenoma was not visualized by gadolinium MRI in 35 cases. The size of visualized pituitary adenoma varied from 0.3 to 29 mm. After first neurosurgery, remission was achieved in 87 (82.8%) patients. After second neurosurgery, remission occurred in 12 patients. Radiation therapy was conducted in 24 patients. Six patients had bilateral adrenalectomy. Two patients died during remission: one patient died from stroke two years after neurosurgery, and the other patient died due to surgery complications. During five-year follow-up after neurosurgery, remission continued in 76 (72.8%) patients, including 27 (77%) of 35 patients without MRI-detected adenoma and 49 (70%) of 70 patients with MRI-detected pituitary adenoma, p=0.15. Sixty-six patients developed recurrence, and 14 patients had active hypercortisolism. Conclusion. There was no correlation between the rate of preoperative MRI-based detection of pituitary adenoma and the rate of remission in neurosurgery patients with Cushing’s disease during the five year follow-up. The size of pituitary adenoma was a risk factor for adenoma recurrence.

Abstract Cushing’s Disease is a well known entity but the difficulty of diagnosis is often underappreciated. Given the wide spectrum of clinical presentation and pitfalls with each diagnostic evaluation, diagnosis of Cushing’s Disease (CD) is often difficult in clinical practice, even with pathological analysis. A 37 year old female with a history of Cushing’s Disease presented for her third transphenoidal resection to our institution. She was diagnosed with a pituitary microadenoma 16 years ago based on MRI, as she had persistent headaches and vision abnormalities. The patient also reported unexplained weight gain, “buffalo hump”, and moon facies at the time. She was diagnosed with CD due to an abnormal 1 mg overnight dexamethasone suppression test (DST) with AM cortisol of 3.03 ug/dl (normal &lt;1.8 microgram/dl). She was on an oral contraceptive pill (OCP) at the time. The patient underwent her first pituitary transsphenoidal resection and was symptom free for about 10 years, after which she had a recurrence of her initial symptoms. She had another abnormal DST while on an OCP and pituitary MRI revealed growth of the pituitary adenoma. Patient underwent a second pituitary surgery with benign postoperative course with a recurrence about 5 years later. The workup prior to her third surgery revealed an abnormal DST while on OC pills with the 8am cortisol being 3.36 ug/dl (&lt;1.8ug/dl), urinary free cortisol 35.4 mcg/24 hour (4-50 mcg/24 hour). 8am ACTH done on a separate day was 48 pg/ml (6-50 pg/ml) with a cortisol of 14.5 ug/dl. Midnight salivary cortisol was not performed. Interval history was still positive for weight gain and headaches, hence she was referred for her third pituitary surgery. Post surgery, the patient was on a short taper of hydrocortisone and 8am cortisol was 32 ug/dl the next day. After a discussion with the pathologist, it was determined that the pathology was suggestive of a corticotroph adenoma with moderate ACTH staining and patchy nuclear staining for TPIT, although the pathologist stated that it was difficult to be certain due to the small tissue size. From the current literature, this patient had an incomplete and equivocal biochemical work up while on OCPs but still had tissue diagnosis supporting CD. Whether this was a recurrence of Cushing’s disease, silent corticotroph adenoma, or non-functioning pituitary adenoma is unclear. This case illustrates the multiple challenges in the diagnosis of Cushing’s disease that may be encountered. 1.Braun LT et al.

Abstract Introduction: Cushing’s Disease (CD) in pregnancy is a rare, but serious disease that adversely impacts maternal and fetal outcomes. As the sole use of metyrapone in the management of CD has been rarely reported, we describe our experience using it to treat a pregnant patient with pre-existing CD. Clinical Case: The patient is a 29-year-old woman with a history of hypertension (HTN), who was diagnosed with CD a year prior to becoming pregnant based on elevated urinary free cortisol (UFC) 209 ug/24h (Reference Range (RR) 6 - 42), positive 1 mg dexamethasone suppression test, elevated ACTH 61 pg/mL (RR 0-46). and an 8 x 8 x 8 mm pituitary adenoma on magnetic resonance imaging (MRI). She underwent trans-sphenoidal adenoma resection 3 months prior to becoming pregnant; however, was found to have persistent disease based on a repeat MRI showing a residual 8 x 8 x 9 mm adenoma extending into the cavernous sinus and UFC 290 ug/24h. The patient discovered 6 weeks later that she was pregnant. She was referred to endocrinology at 12 weeks’ gestation, where she was experiencing easy bruising and taking labetalol 400 mg twice daily for HTN. UFC was 768 ug/24h and midnight salivary cortisols were 0.175 and 0.625 ug/dL (RR &lt;0.010 - 0.090). Surgery was deemed to be high risk given the proximity of the tumor to the cavernous sinus and likelihood of residual disease. She was started on metyrapone 250 mg twice a day, and was uptitrated to 1000mg three times daily by the time of delivery with a UFC of 120 ug/24h (goal &lt; 150 ug/24h). Her pregnancy was also complicated by diet-controlled gestational diabetes and cervical insufficiency requiring cerclage. Otherwise, her HTN was well controlled on labetolol and she remained normokalemic. The patient was induced at 37 weeks gestation and was given stress dose steroids along with metyrapone. She delivered a healthy baby boy without any complications. Discussion: CD during pregnancy is a rare disease, with the best outcomes in published cases seen with surgical intervention. This case highlights the use of metyrapone, a steroidogenesis inhibitor, as a sole therapy in cases where surgery is deemed to be high risk and unlikely curative due to location of the tumor. While it is effective in reducing cortisol levels, close surveillance of patients is required for worsening HTN, hypokalemia, and potential adrenal insufficiency. Though no fetal adverse events have been reported, the medication does cross the placenta and longterm effects are unknown.

ContextAlthough the endoscopic technique of transsphenoidal pituitary surgery (TS) has been widely adopted, reports on its results in Cushing's disease (CD) are still scarce and no studies have investigated long-term recurrence rates. This is the largest endoscopic series published till now.ObjectiveTo gain insight into the role of endoscopic TS as a primary treatment option for CD, especially in patients with magnetic resonance imaging (MRI)-negative CD and (invasive) macroadenomas.DesignRetrospective cohort study.Patients and methodsThe medical records of 86 patients with CD who underwent endoscopic TS were examined. Data on preoperative and postoperative evaluation, perioperative complications, and follow-up were collected. Remission was defined as disappearance of clinical symptoms with a fasting plasma cortisol level ≤50 nmol/l either basal or after 1 mg dexamethasone.ResultsThe remission rate in different adenoma subclasses varied significantly: 60% in MRI-negative CD (n=20), 83% in microadenomas (n=35), 94% in noninvasive macroadenomas (n=16), and 40% in macroadenomas that invaded the cavernous sinus (n=15). The recurrence rate was 16% after 71±39 months of follow-up (mean±s.d., range 10–165 months).ConclusionsEndoscopic TS is a safe and effective treatment for all patients with CD. Recurrence rates after endoscopic TS are comparable with those reported for microscopic TS. Our data suggest that in patients with noninvasive and invasive macroadenomas, the endoscopic technique of TS should be the treatment of choice as remission rates seem to be higher than those reported for microscopic TS, although no comparative study has been performed.

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 &gt;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.
