Endogenous Cushing's syndrome (CS), a rare endocrine disorder characterized by cortisol hypersecretion, is associated with psychiatric and neurocognitive disorders. Major depression, mania, anxiety, and neurocognitive impairment are the most important clinical abnormalities. Moreover, patients most often complain of impairment in quality of life, interference with family life, social, and work performance. Surprisingly, after hypercortisolism resolution, despite the improvement of the overall prevalence of psychiatric and neurocognitive disorders, the brain volume loss at least partially persists and it should be noted that some patients may still display depression, anxiety, panic disorders, and neurocognitive impairment. This brief review aimed at describing the prevalence of psychiatric and neurocognitive disorders and their characterization both during the active and remission phases of CS. The last section of this review is dedicated to quality of life, impaired during active CS and only partially resolved after resolution of hypercortisolism.

Objective: Cabergoline (CAB) has been found to be associated with increased risk of cardiac valve regurgitation in Parkinson's disease, whereas several retrospective analyses failed to detect a similar relation in hyperprolactinemic patients. The current study aimed at investigating cardiac valve disease before and after 24 and 60 months of continuous treatment with CAB only in patients with hyperprolactinemia. Subjects and methods: Forty patients (11 men and 29 women, aged 38.7G12.5 years) newly diagnosed with hyperprolactinemia entered the study. Cumulative CAB dose ranged from 12 to 588 mg (median 48 mg) at 24 months and 48-1260 mg (median 149 mg) at 60 months. All patients underwent a complete trans-thoracic echocardiographic examination. Valve regurgitation was assessed according to the American Society of Echocardiography. Results: At baseline, the prevalence of trace mitral, aortic, pulmonic, and tricuspid regurgitations was 20, 2.5, 10, and 40% respectively, with no patient showing clinically relevant valvulopathy. After 24 months, no change in the prevalence of trace mitral (PZ0.78) and pulmonic (PZ0.89) regurgitations and of mild aortic (PZ0.89) and tricuspid (PZ0.89) regurgitations was found when compared with baseline. After 60 months, the prevalence of trace tricuspid regurgitation was only slightly increased when compared with that after 24 months (37.5%; PZ0.82), but none of the patients developed significant valvulopathy. No correlation was found between cumulative dose and prevalence or grade of valve regurgitation at both evaluations. Prolactin levels normalized in all patients but one. Conclusion: CAB does not increase the risk of significant cardiac valve regurgitation in prolactinomas after the first 5 years of treatment.

The distinction between pseudo-Cushing’s states (PCS) and Cushing’s syndrome (CS) poses a significant clinical challenge even for expert endocrinologists. A patient’s clinical history can sometimes help to distinguish between them (as in the case of alcoholic individuals), but the overlap in clinical and laboratory findings makes it difficult to arrive at a definitive diagnosis. We aim to describe the most common situations that can give rise to a condition resembling overt endogenous hypercortisolism and try to answer questions that physicians often face in clinical practice. It is important to know the relative prevalence of these different situations, bearing in mind that most of the conditions generating PCS are relatively common (such as metabolic syndrome and polycystic ovary syndrome), while CS is rare in the general population. Physicians should consider CS in the presence of additional features. Appropriate treatment of underlying conditions is essential as it can reverse the hormonal abnormalities associated with PCS. Close surveillance and a thorough assessment of a patient’s hormone status will ultimately orient the diagnosis and treatment options over time.

A phase III study has demonstrated that 6-month pasireotide treatment induced disease control with good safety in 15–26% of patients with Cushing’s disease (CD). The aim of the current study was to evaluate the 6-month efficacy and safety of pasireotide treatment according to the real-world evidence. Thirty-two CD patients started pasireotide at the dose of 600 µg twice a day (bid) and with the chance of up-titration to 900 µg bid, or down-titration to 450 or 300 µg bid, on the basis of urinary cortisol (UC) levels or safety. Hormonal, clinical and metabolic parameters were measured at baseline and at 3-month and 6-month follow-up, whereas tumour size was evaluated at baseline and at 6-month follow-up. At baseline, 31 patients had very mild to moderate disease and 1 patient had very severe disease. Five (15.6%) patients discontinued treatment for adverse events; the remaining 27 patients (26 with very mild to moderate disease and 1 with very severe disease), reached 6-month follow-up. Considering the group of patients with very mild to moderate disease, responsiveness, defined by the normalization (<1 the upper limit of normal range, ULN) or near normalization (>1 and ≤1.1 ULN) of UC levels, was registered in 21 patients (full control in 19 and near control in 2), corresponding to 67.7% and 80.8% according to an “intention-to-treat” or “per-protocol” methodological approach, respectively. Weight, body mass index, waist circumference, as well as total and LDL-cholesterol significantly decreased, whereas fasting plasma glucose and glycated haemoglobin significantly increased. Hyperglycaemia was documented in 81.2%, whereas gastrointestinal disturbances in 40.6% of patients. In conclusion, in the real-life clinical practice, pasireotide treatment normalizes or nearly normalizes UC in at least 68% of patients with very mild to moderate disease, with consequent improvement in weight, visceral adiposity and lipid profile, despite the occurrence or deterioration of diabetes in the majority of cases, confirming the usefulness of this treatment in patients with milder disease and without uncontrolled diabetes.
