Decreased bone mineral density (BMD) and disturbances in glucose metabolism are common complications of Cushing’s disease. Many recent studies have shown that hyperinsulinemia in type 2 diabetes mellitus (DM) may lead to higher BMD as compared to healthy individuals. The aim of the present study was to investigate the possible relationships between BMD, serum markers of bone metabolism and plasma cortisol concentrations. The second objective was to determine whether the p...

Many previous studies have shown decreased bone mineral density (BMD) in patients with endogenous hypercortisolism, although data on the severity of bone disease are contradictory. There are very sparse data about the correlations between plasma cortisol concentrations and BMD.The study included 188 patients with clinically inactive adrenal adenomas (IAA) and 30 patients with ACTH-independent Cushing’s syndrome (CS) due to adrenocortical adenomas. A...

Familial isolated pituitary adenoma (FIPA) occurs if two or more members of a family develop pituitary adenoma with no features of multiple endocrine neoplasia type 1 or Carney complex. FIPA is an autosomal dominant disease with incomplete penetrance. FIPA families can be divided into two distinct groups based on genetic and phenotypic features. In 20% of FIPA families mutations have been identified in the aryl hydrocarbon receptor interacting protein (AIP) gene. The AIP-posit...

During pregnancy of healthy women, a great increase of serum little prolactin occurs. In has been also reported that a significant amount of serum big big prolactin (termed macroprolactinemia) may be detected in about 4% of healthy pregnant women. Because the occurrence of macroprolactinemia during pregnancy of women with prolactin-producing pituitary microadenomas has not been extensively investigated, we determined both little and big big prolactin in serum of 97 women with ...
