Abstract Background Despite advances in diagnostic and therapeutic approach, Cushing’s disease (CD) presents a challenging situation for the treating physician. Aims To elucidate current challenges, present strengths and pitfalls of existing diagnostic tests, enlighten the need for new diagnostic approaches, appraise the effects of surgery and available pharmacological agents and identify future perspectives regarding CD. Materials and methods Systematic search to PubMed and Medline databases for publications mainly over the last five years. Results Mutations in the ubiquitin specific peptidase 8 gene have been recently identified in functional sporadic corticotroph adenomas causing CD. Since the prevalence of obesity and metabolic syndrome is rapidly increasing, new diagnostic tests are necessary to differentiate these conditions. Next to the traditional tests, a cutoff of preoperative ACTH/cortisol ratio, an ultrasensitive late night salivary cortisol assay and the desmopressin test have been suggested as valid tools for the diagnosis and differential diagnosis of CD. Transsphenoidal surgery with variable remission and recurrence rates presents the treatment of choice for CD. Medical therapy consists of adrenal-targeted drugs e. g. ketoconazole, metyrapone, etomidate and mitotane and pituitary-targeted drugs e. g. pasireotide, cabergoline and retinoic acid. Conclusions CD is associated to a significant clinical burden, since numerous comorbidities persist after long-term biochemical control. These chronically ill patients show an increased mortality despite disease remission. Clinicians should treat comorbidities aggressively and seek for appropriate consultations. Structured consultation hours and expert excellence networks are needed in order to allow optimal, individualized care for affected patients, reverse increased morbidity and mortality and identify tumor recurrence early.

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.

Despite many recent advances, the management of patients with Cushing's disease continues to be challenging. Cushing's syndrome is a complex metabolic disorder that is a result of excess glucocorticoids. Excluding the exogenous causes, adrenocorticotropic hormone–secreting pituitary adenomas account for nearly 70% of all cases of Cushing's syndrome. The suspicion, diagnosis, and differential diagnosis require a logical systematic approach with attention paid to key details at each investigational step. A diagnosis of endogenous Cushing's syndrome is usually suspected in patients with clinical symptoms and confirmed by using multiple biochemical tests. Each of the biochemical tests used to establish the diagnosis has limitations that need to be considered for proper interpretation. Although some tests determine the total daily urinary excretion of cortisol, many others rely on measurements of serum cortisol at baseline and after stimulation (e.g., after corticotropin-releasing hormone) or suppression (e.g., dexamethasone) with agents that influence the hypothalamic-pituitary-adrenal axis. Other tests (e.g., measurements of late-night salivary cortisol concentration) rely on alterations in the diurnal rhythm of cortisol secretion. Because more than 90% of the cortisol in the circulation is protein bound, any alteration in the binding proteins (transcortin and albumin) will automatically influence the measured level and confound the interpretation of stimulation and suppression data, which are the basis for establishing the diagnosis of Cushing's syndrome. Although measuring late-night salivary cortisol seems to be an excellent initial test for hypercortisolism, it may be confounded by poor sampling methods and contamination. Measurements of 24-hour urinary free-cortisol excretion could be misleading in the presence of some pathological and physiological conditions. Dexamethasone suppression tests can be affected by illnesses that alter the absorption of the drug (e.g., malabsorption, celiac disease) and by the concurrent use of medications that interfere with its metabolism (e.g., inducers and inhibitors of the P450 enzyme system). In this review, the authors aim to review the pitfalls commonly encountered in the workup of patients suspected to have hypercortisolism. The optimal diagnosis and therapy for patients with Cushing's disease require the thorough and close coordination and involvement of all members of the management team.

Introduction It is unclear whether the proportions of remission and the recurrence rates differ between endoscopic transsphenoidal surgery (TS) and microscopic TS in Cushing’s disease (CD); thus, we conducted a systematic review and meta-analysis to evaluate studies of endoscopic TS and microscopic TS. Methods We conducted a comprehensive search of PubMed to identify relevant studies. Remission and recurrence were used as outcome measures following surgical treatment of CD. Results A total of 24 cohort studies involving 1670 adult patients were included in the comparison. Among these studies, 702 patients across 9 studies underwent endoscopic TS, and 968 patients across 15 studies underwent microscopic TS. Similar baseline characteristics were observed in both groups. There was no significant difference in remission between the two groups: 79.7% (95% CI: 73.1–85.0%) in the endoscopic group and 76.9% (95% CI: 71.3–81.6%) in the microscopic group (P = 0.485). It appears that patients who underwent endoscopic surgery experience recurrence less often than patients who underwent microscopic surgery, with recurrence proportions of 11.0% and 15.9%, respectively (P = 0.134). However, if follow-up time is taken into account, both groups had a recurrence rate of approximately 4% per person per year (95% CI: 3.1–5.4% and 3.6–5.1%, P = 0.651). Conclusions We found that remission proportion and recurrence rate were the same in patients who underwent endoscopic TS as in patients who underwent microscopic TS. The definition of diagnosis, remission and recurrence should always be considered in the studies assessing therapeutic efficacy in CD.

Abstract Context: The diagnosis, differential diagnosis, and treatment of Cushing’s syndrome are challenging problems in clinical endocrinology. We focus on critical questions addressing screening for Cushing’s syndrome, differentiation of Cushing’s subtypes, and treatment options. Evidence Acquisition: Ovid’s MEDLINE (1996 through April 2006) was used to search the general literature. We also relied on previously published reviews and a recent monograph and cite a mix of primary articles and recent reviews. Evidence Synthesis: Although this article represents our opinion, it draws heavily on a recent consensus statement from experts in the field and a recent monograph on Cushing’s syndrome. Conclusions: We concluded that: 1) measurement of late-night or bedtime salivary cortisol is a useful approach to screen for Cushing’s syndrome; 2) measurement of suppressed plasma ACTH by immunometric assay is useful to differentiate ACTH-dependent and -independent Cushing’s syndrome; 3) inferior petrosal sinus sampling for ACTH should be performed in patients with ACTH-dependent hypercortisolism in whom a pituitary magnetic resonance imaging is normal or equivocal (in the absence of a pituitary ACTH gradient, prolactin levels should be measured to confirm the integrity of venous sampling); 4) computed tomography of the chest and abdomen and somatostatin receptor scintigraphy should be performed in patients with the occult ectopic ACTH syndrome; and 5) patients with Cushing’s disease should be referred to a neurosurgeon with extensive experience operating on corticotroph microadenomas. Bilateral laparoscopic adrenalectomy should be considered in patients with Cushing’s disease who fail therapies directed at the pituitary.

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.

AbstractDue to high morbidity and mortality of untreated hypercortisolism, a prompt diagnosis is essential. Measurement of late-night salivary cortisol provides a simple and non-invasive method. However, thresholds and reference ranges differ among studies. The goal of this study was to define a threshold of late-night salivary cortisol for the diagnosis of hypercortisolism based on the used assay. Moreover, the influence of different aetiologies of hypercortisolism and individual comorbidities were investigated. Prospective analyses of 217 patients, including 36 patients with proven hypercortisolism were carried out. A sum of 149 patients with suspicion of hypercortisolism but negative endocrine testing and 32 patients with hypercortisolism in remission served as control group. Late-night salivary cortisol was measured using an automated chemiluminescence immunoassay. Cut-off values were calculated by ROC analysis. The calculated cut-off value for the diagnosis of hypercortisolism was 10.1 nmol/l (sensitivity 94%; specificity 84%). Only slightly lower thresholds were obtained in patients with suspected hypercortisolism due to weight gain/obesity (9.1 nmol/l), hypertension or adrenal tumours (both 9.8 nmol/l) or pituitary adenomas (9.5 nmol/l). The late-night salivary cortisol threshold to distinguish between Cushing’s disease and Cushing’s disease in remission was 9.2 nmol/l. The cut-off value for the diagnosis of ectopic ACTH-production was 109.0 nmol/l (sensitivity 50%, specificity 92%). Late-night salivary cortisol is a convenient and reliable parameter for the diagnosis of hypercortisolism. Except for ectopic ACTH-production, thresholds considering different indications for evaluation of hypercortisolism were only slightly different. Therefore, they might only be useful if late-night salivary cortisol results near the established cut-off value are present.
