Classical congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21-OHD) in adult males: Clinical presentation, hormone function and the detection of adrenal and testicular adrenal rest tumors (TARTs).

Introduction: 21-hydroxylase deficiency (21-OHD) is the most common form of congenital adrenal hyperplasia (CAH). In adulthood, most studies are reported in females. By contrast, data on adult males are scarce.

Autoimmune and non-autoimmune thyroid dysfunction in HCV infected and HCV-HIV co-infected patients before and after interferon alpha therapy: A prospective study.

Introduction: Autoimmune thyroid diseases are reported in no treated hepatitis C virus (HCV) infection. The standard interferon alpha (IFNα) treatment is associated with an increase of thyroid damage and dysfunction. The present cohort prospective study compared thyroid function and autoimmunity in HCV patients' monoinfected and coinfected HCV-HIV at baseline, during and after IFNα therapy.

Primary aldosteronism: Aldosterone/renin ratio cut-off points.

Introduction: Primary aldosteronism (PA) is the most common cause of endocrine hypertension, with a prevalence rate of 6-12% in hypertensive patients. Aldosterone/renin ratio (ARR) is the screening test of choice for PA. Because of the variable cut-off points of ARR, reference values related to the populations and methods considered are recommended.
