    Context: Dopamine agonist (DA)-induced impulse control disorder (ICD) in patients with prolactinomas is not sufficiently known. Objective: To evaluate the prevalence of DA-induced ICDs and possible risk factors related to these disorders in patients with prolactinoma. Design, Setting, and Participants: This is a cross-sectional multicenter study involving 308 patients with prolactinoma followed up in tertiary referral centers who received at least three months of DA therapy. DA-induced ICDs (pathological gambling, hypersexuality, compulsive shopping, and compulsive eating) and impulsivity were assessed using the Questionnaire for ImpulsiveCompulsive Disorders in Parkinson Disease and the Barratt Impulsiveness Scale-11, respectively. Patients were evaluated in terms of parameters related to ICD development. Results: Any ICD prevalence was 17% (n = 51). Hypersexuality was most common (6.5%). Although any ICD and hypersexuality were more common in male patients (P = 0.009, P < 0.001, respectively), compulsive eating was more common in female patients (P = 0.046). Current smoking, alcohol use, and gambling history were more frequent (P = 0.033, P = 0.002, P = 0.008, respectively) in patients with any ICD. In Barratt Impulsiveness Scale-11 total, attentional, motor, and nonplanning scores were higher in patients with any ICD (P < 0.001). Current smoking and alcohol use were more frequent (P = 0.007, P = 0.003, respectively) and percentage increase of testosterone levels at last visit was higher (P = 0.021) in male patients with prolactinomas with hypersexuality. Conclusion: Any ICD may be seen in one of six patients with prolactinoma who are receiving DA therapy. Endocrinology specialists should be aware of this side effect, particularly in male patients with a history of gambling, smoking, or alcohol use.

    Objective Primary hypophysitis might be challenging to diagnose, and there is a lack of evidence regarding optimal treatment strategies due to rarity of the disease. We aim to investigate the clinical features and compare the outcomes of different management strategies of primary hypophysitis in a large group of patients recruited on a nationwide basis.Design A retrospective observational study.Methods The demographic, clinical, and radiologic features and follow-up data were collected in study protocol templates and analyzed.Results One hundred and thirteen patients (78.8% female, median age: 36 years) were included. Lymphocytic (46.7%) and granulomatous hypophysitis (35.6%) were the prevailing subtypes out of 45 patients diagnosed after pathologic investigations. Headache (75.8%) was the most common symptom, and central hypogonadism (49.5%) was the most common hormone insufficiency. Of the patients, 52.2% were clinically observed without interventions, 18.6% were started on glucocorticoid therapy, and 29.2% underwent surgery at presentation. Headache, suprasellar extension, and chiasmal compression were more common among glucocorticoid-treated patients than who were observed. Cox regression analysis revealed higher hormonal and radiologic improvement rates in the glucocorticoid-treated group than observation group (hazard ratio, 4.60; 95% CI, 1.62-12.84 and HR, 3.1; 95% CI, 1.40-6.68, respectively). The main indication for surgery was the inability to exclude a pituitary adenoma in the presence of compression symptoms, with a recurrence rate of 9%.Conclusion The rate of spontaneous improvement might justify observation in mild cases. Glucocorticoids proved superior to observation in terms of hormonal and radiologic improvements. Surgery may not be curative and might be considered in indeterminate, treatment-resistant, or severe cases.
