Objective: To assess the effect of somatostatin analogs (SSTA) on mortality in relation to metabolic control of acromegaly after pituitary surgery.Design: A retrospective study in two large tertiary referral centers in The Netherlands.Patients and methods: Three hundred and nineteen patients with acromegaly in whom pituitary surgery was performed as primary therapy between January 1980 and July 2017 were included (total follow-up: ...

Background and aims: Patients with GH secreting or nonfunctioning pituitary adenoma (NFPA) have high mortality ratios, despite enhancement of the old therapies. The aim of the study is to analyze the relationship between mortality and risk factors, including therapy, in patients with acromegaly (ACM) and NFPA evaluated in the last 16 years.Methods: We evaluated retrospectively 749 patients with pituitary adenoma (435F/314M), 386 with ACM and 363 with NFP...

Pharmacologic treatment of acromegaly is currently based upon assay-error strategy in which first generation somatostatin analogs (SSA) is the first-line treatment. However, about 50% of patients do no respond adequately to SSA. We aimed to evaluate the potential usefulness of including studies of molecular markers identifying poor response to SSA for prescription of pharmacologic treatment in acromegalic patients in which SSA was prescribed before surgical therapy.<p clas...

Introduction: Glucose metabolism impairment is a common complication of acromegaly. Pegvisomant (PEG) is used as second-line medical treatment in acromegaly. Data from literature suggest a positive effect of PEG on glucose metabolism but a meta-analysis has never been performed.Aim: To address the following questions: i) does PEG affect glucose metabolism? ii) does the effect correlate with disease control?Methods: We performed a m...

Growth hormone (GH) responsive cells are extensively distributed in central nervous system, including in neurons of the arcuate (ARH) and ventromedial nucleus (VMH) of hypothalamus, areas that control food intake, energy expenditure and blood glucose. During metabolic stresses, such as food restriction and hypoglycemia, GH secretion is stimulated and may be important to maintain survival. In the present study, we first verified that an acute GH injection stimulates food intake...
