Diabetes mellitus secondary to Cushing's disease
Associated with important comorbidities that significantly reduce patients’ overall wellbeing and life expectancy, Cushing’s disease (CD) is the most common cause of endogenous hypercortisolism. Glucocorticoid excess can lead to diabetes, and although its prevalence is probably underestimated, up to 50% of patients with CD have varying degrees of altered glucose metabolism. Fasting glycemia may nevertheless be normal in some patients in whom glucocorticoid excess leads primarily to higher postprandial glucose levels. An oral glucose tolerance test should thus be performed in all CD patients to identify glucose metabolism abnormalities. Since diabetes mellitus (DM) is a consequence of cortis…
Mitotane Concentrations Influence Outcome in Patients With Advanced Adrenocortical Carcinoma
Mitotane is the main option of treatment for advanced adrenocortical carcinoma (ACC). However, limited evidence is available regarding the impact of plasma mitotane levels on patient outcome. To address this question, we retrospectively analyzed patients with advanced ACC treated with mitotane for &ge
Incretin Response to Mixed Meal Challenge in Active Cushing’s Disease and after Pasireotide Therapy
Cushing’s disease (CD) causes diabetes mellitus (DM) through different mechanisms in a significant proportion of patients. Glucose metabolism has rarely been assessed with appropriate testing in CD; we aimed to evaluate hormonal response to a mixed meal tolerance test (MMTT) in CD patients and analyzed the effect of pasireotide (PAS) on glucose homeostasis. To assess gastro-entero-pancreatic hormones response in diabetic (DM+) and non-diabetic (DM–) patients, 26 patients with CD underwent an MMTT. Ten patients were submitted to a second MMTT after two months of PAS 600 µg twice daily. The DM+ group had significantly higher BMI, waist circumference, glycemia, HbA1c, ACTH le…
Effects of pasireotide treatment on coagulative profile: a prospective study in patients with Cushing's disease.
Introduction: Cushing’s disease (CD) is characterized by procoagulative profile. Treatment with cortisol-reducing medications might normalize the coagulation impairment potentially eliminating the risk of thromboembolic complications. Aim: The aim of this prospective study is to evaluate the effectiveness of 6–12 months of treatment with pasireotide (Signifor®, Novartis) 600 µg twice daily on coagulative factors in 21 patients (16 females, mean age 46 ± 12.2 years) with CD. Biochemical, hormonal (urinary free cortisol, UFC; late night salivary cortisol, LNSC; ACTH) and coagulative parameters as Protrombin time (PT), aPTT, factors VIII, IX and XI, antithrombin III, protein C, protein S, fibr…
