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 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 (> o ≤ 1 UNL) and HCM (> 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.

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.

A Prospective Study

Context and objectiveThe role of cabergoline in Cushing's disease (CD) remains controversial. The experience is limited to case reports and few open studies that report the effects determined after ≥1 month of treatment. In prolactinomas and dopamine-responsive GH-secreting tumours, effects of cabergoline are seen within days or weeks. Here, we searched for short-term effects of cabergoline in CD.DesignTwenty patients (19 naïve and one recurrent) were included in a prospective study. Cabergoline was administered in increasing doses of 0.5–5 mg/week over 6 weeks.MethodsUrinary free cortisol (UFC) 24 h, morning cortisol and ACTH, and salivary cortisol at 0800, 1600 and 2300 h were determined once weekly throughout. Diurnal curves (six samples) of serum cortisol were measured at start and end.ResultsAt study end, the median cabergoline dose was 5 mg, range 2.5–5 mg/week. The prolactin levels, markers of compliance, were suppressed in all patients. During the treatment, hypercortisolism varied, gradual and dose-dependent reductions were not seen. Five patients had a >50% decrease of UFC, three had a >50% rise of UFC. Salivary cortisol at 2300 h showed a congruent >50% change with UFC in two of the five cases with decreased UFC, and in one of the three cases with increased UFC. One patient with decreases in both UFC and 2300 h salivary cortisol also had a reduction in diurnal serum cortisol during the course of the study.ConclusionsCabergoline seems to be of little value in the management of CD. Only one patient had a response-like pattern. Given the known variability of disease activity in CD, this might represent a chance finding.

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.

Abstract OBJECTIVE Transsphenoidal surgery is the preferred treatment modality for adrenocorticotropic hormone-secreting pituitary adenomas. In the past 2 decades, several institutions in the United States and Europe have reported remission rates of 70 to 85% after transsphenoidal surgery for treatment of Cushing's disease. We analyzed our postoperative results for a large cohort of patients with Cushing's disease. METHODS Eighty-two patients with adrenocorticotropic hormone-secreting adenomas (79 microadenomas and 3 macroadenomas) underwent transsphenoidal surgery between 1990 and 2000. Seventy-seven patients were surgically treated for the first time, and 13 patients underwent reoperations (5 had undergone the first operation elsewhere) because of previous surgical failure (10 patients) or recurrence (3 patients). The mean postoperative follow-up period was 4.2 ± 2.8 years. Biochemical remission was defined as postoperative normalization of elevated 24-hour urinary free cortisol secretion and suppression of morning cortisol levels with 1 mg of dexamethasone. RESULTS Remission was achieved for 78% of all patients after one operation and for 62% of patients who underwent a second operation. The recurrence rate was 5%. Ten patients did not exhibit a visible tumor on magnetic resonance imaging scans, and the other patients were divided according to adenoma size (2–5 or 6–10 mm). Remission rates were similar for the three groups of patients (78–80%). Pituitary tumor stained for adrenocorticotropic hormone was detected in 78% of resected pituitary tissue specimens obtained from patients who achieved remission, compared with 53% from patients who experienced surgical failure (P = 0.06). CONCLUSION Our series demonstrates the efficacy of transsphenoidal surgery for Cushing's disease resulting from pituitary microadenomas. Microadenoma size had no effect on the remission rate. Reoperations are indicated after initial surgical failures.

ContextAlthough transsphenoidal surgery remains the first-line treatment in Cushing's disease (CD), recurrence is observed in about 20% of cases. Adjunctive treatments each have specific drawbacks. Despite its inhibitory effects on steroidogenesis, the antifungal drug ketoconazole was only evaluated in series with few patients and/or short-term follow-up.ObjectiveAnalysis of long-term hormonal effects and tolerance of ketoconazole in CD.DesignA total of 38 patients were retrospectively studied with a mean follow-up of 23 months (6–72).SettingAll patients were treated at the same Department of Endocrinology in Marseille, France.PatientsThe 38 patients with CD, of whom 17 had previous transsphenoidal surgery.InterventionKetoconazole was begun at 200–400 mg/day and titrated up to 1200 mg/day until biochemical remission.Main outcome measuresPatients were considered controlled if 24-h urinary free cortisol was normalized.ResultsFive patients stopped ketoconazole during the first week because of clinical or biological intolerance. On an intention to treat basis, 45% of the patients were controlled as were 51% of those treated long term. Initial hormonal levels were not statistically different between patients controlled or uncontrolled. Ketoconazole was similarly efficacious as a primary or postoperative treatment. Among 15 patients without visible adenoma at initial evaluation, subsequent follow-up allowed identification of the lesion in five cases. No adrenal insufficiency was observed. Adverse effects were rare in patients treated long term.ConclusionsKetoconazole is a safe and efficacious treatment in CD, particularly in patients for whom surgery is contraindicated, or delayed because of the absence of image of adenoma on magnetic resonance imaging.

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 <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 < 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.

Abstract Context: Few studies have systematically analyzed the long-term recurrence rates of Cushing’s disease after initial successful transsphenoidal surgery. Setting: This was a retrospective review of patients treated at the University of Virginia Medical Center. Patients: A total of 215 subjects with Cushing’s disease who underwent initial transsphenoidal surgery for resection of a presumed pituitary microadenoma from 1992–2006 were included. Main Outcome Measures: Remission and recurrence rates of Cushing’s disease were examined. Recurrence was defined as an elevated 24-h urine free cortisol with clinical symptoms consistent with Cushing’s disease. Results: Of the 215 patients who underwent transsphenoidal surgery for Cushing’s disease, surgical remission was achieved in 184 (85.6%). The mean length of follow-up was 45 months. Actuarial recurrence rates of Cushing’s disease after initially successful transsphenoidal surgery at 1, 2, 3, and 5 yr were 0.5, 6.7, 10.8, and 25.5%, respectively. Among the 184 patients who achieved remission, 32 (17.4%) patients followed for more than 6 months ultimately had a recurrence of Cushing’s disease. The median time to recurrence was 39 months. Immediate postoperative hypocortisolemia (serum cortisol ≤ 2 μg/dl within 72-h surgery) was achieved in 97 (45.1%) patients. Patients who had postoperative serum cortisol of more than 2 μg/dl were 2.5 times more likely to have a recurrence than patients who had serum cortisol less than or equal to 2 μg/dl (odds ratio = 2.5; 95% confidence interval 1.12–5.52; P = 0.022). Conclusions: A quarter of the patients with Cushing’s disease who achieve surgical remission after transsphenoidal surgery, recur with long-term follow-up. This finding emphasizes the need for continued biochemical and clinical follow-up to ensure remission after surgery.

Abstract Introduction The clinical practice and research in the diagnosis and management of Cushing’s disease remains heterogeneous and challenging to this day. We sought to establish the characteristics of Cushing’s disease, and the trends in diagnosis, management and reporting in this field. Methods Searches of PubMed and Embase were conducted. Study protocol was registered a-priori. Random-effects analyses were conducted to establish numerical estimates. Results Our screening returned 159 papers. The average age of adult patients with Cushing’s disease was 39.3, and 13.6 for children. The male:female ratio was 1:3. 8% of patients had undergone previous transsphenoidal resection. The ratio of macroadenomas: microadenomas:imaging-undetectable adenomas was 18:53:29. The most commonly reported preoperative biochemical investigations were serum cortisol (average 26.4µg/dL) and ACTH (77.5pg/dL). Postoperative cortisol was most frequently used to define remission (74.8%), most commonly with threshold of 5µg/dL (44.8%). Average remission rates were 77.8% with recurrence rate of 13.9%. Median follow-up was 38 months. Majority of papers reported age (81.9%) and sex (79.4%). Only 56.6% reported whether their patients had previous pituitary surgery. 45.3% reported whether their adenomas were macroadenoma, microadenoma or undetectable. Only 24.1% reported preoperative cortisol, and this did not improve over time. 60.4% reported numerical thresholds for cortisol in defining remission, and this improved significantly over time (p = 0.004). Visual inspection of bubbleplots showed increasing preference for threshold of 5µg/dL. 70.4% reported the length of follow up. Conclusion We quantified the characteristics of Cushing’s disease, and analysed the trends in investigation and reporting. This review may help to inform future efforts in forming guidelines for research and clinical practice.

Abstract Background Transsphenoidal surgery (TSS) to resect an adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma is the first-line treatment for Cushing’s disease (CD), with increasing usage of endoscopic transsphenoidal (ETSS) technique. The aim of this study was to assess remission rates and postoperative complications following ETSS for CD. Methods A retrospective analysis of a prospective single-surgeon database of consecutive patients with CD who underwent ETSS between January 2012–February 2020. Post-operative remission was defined, according to Endocrine Society Guidelines, as a morning serum cortisol < 138 nmol/L within 7 days of surgery, with improvement in clinical features of hypercortisolism. A strict cut-off of < 50 nmol/L at day 3 post-op was also applied, to allow early identification of remission. Results A single surgeon (MJ) performed 43 ETSS in 39 patients. Pre-operative MRI localised an adenoma in 22 (56%) patients; 18 microadenoma and 4 macroadenoma (2 with cavernous sinus invasion). IPSS was carried out in 33 (85%) patients. The remission rates for initial surgery were 87% using standard criteria, 58% using the strict criteria (day 3 cortisol < 50 nmol/L). Three patients had an early repeat ETSS for persistent disease (day 3 cortisol 306-555 nmol/L). When the outcome of repeat early ETSS was included, the remission rate was 92% (36/39) overall. Remission rate was 94% (33/35) when patients with macroadenomas were excluded. There were no cases of CSF leakage, meningitis, vascular injury or visual deterioration. Transient and permanent diabetes insipidus occurred in 33 and 23% following first ETSS, respectively. There was one case of recurrence of CD during the follow-up period of 24 (4–79) months. Conclusion Endoscopic transsphenoidal surgery produces satisfactory remission rates for the primary treatment of CD, with higher remission rates for microadenomas. A longer follow-up period is required to assess recurrence rates. Patients should be counselled regarding risk of postoperative diabetes insipidus.
