Analysis of therapy monitoring in the International Congenital Adrenal Hyperplasia Registry.

Objective: Congenital adrenal hyperplasia (CAH) requires exogenous steroid replacement. Treatment is commonly monitored by measuring 17-OH progesterone (17OHP) and androstenedione (D4).

Design: Retrospective cohort study using real-world data to evaluate 17OHP and D4 in relation to hydrocortisone (HC) dose in CAH patients treated in 14 countries.

Insulin resistance and insulin secretion in non-diabetic acromegalic patients.

Unlabelled: Insulin resistance (IR) can be induced by high amounts of growth hormone (GH).

Aim: To set up, in acromegaly without diabetes mellitus, a correlation between the disease activity in GH-secreting adenoma (AA) - assessed by minimum GH serum level during an oral glucose tolerance test (OGTT) - and severity of insulin resistance (IR), assessed by HOMA-IR index.

Methods: 75 out of 88 consecutive patients with acromegaly hospitalized in our department were included in this study.

Beta-cell dysfunctions and insulin resistance in subjects with increased risk for type 2 diabetes mellitus.

The aim of this study was to test if a beta-cell defect is associated to deterioration of glucose tolerance early during the natural history of the type 2 diabetes mellitus. In 41 overweight women, with macrosomic infants in their antecedent deliveries, measures of insulin response and insulin sensitivity were derived from a short (45 min) iv glucose test. The early (EIR) and the late (LIR) phase insulin responses and the insulin sensitivity index (Si) were calculated.
