Prevalence of hypopituitarism in patients with cerebrovascular disease

OBJECTIVE: An increased risk of cardiovascular morbidity and mortality in adult GH deficiency (GHD) may be related to hypopituitarism but also to the presence of the metabolic syndrome (MetS). Our objective was to investigate the characteristics and prevalence of MetS as well as its comorbidities in adult GHD. Design In KIMS (Pfizer International Metabolic Database) 2479 patients with severe adult-onset GHD, naïve to GH replacement, with complete information on all MetS components were found...

Stroke is one of the main causes of death and disability in the adult population. Changes in pituitary hormone secretion may be observed during the acute phase of stroke, representing part of the adaptive response to injury. However, reduced pituitary hormone secretion, caused by pituitary and/or hypothalamus damage, may also occur. Hypopituitarism has been observed in 19% of patients with ischemic stroke and 47% of patients with subarachnoid hemorrhage, presenting as an isolated deficiency in most cases. Diabetes insipidus is very rare...

We recently reported that female patients with hypopituitarism receiving controlled thyroid and steroid hormone substitution, but without GH replacement, had a more than 2-fold increase in cardiovascular mortality compared to the general population. In the present study we investigated the incidence of cardiovascular disease as well as the prevalence of cardiovascular risk factors in 33 females with hypopituitarism for 6-46 yr (median, 18) compared to those in 33 control subjects recruited from the general population in the same geographical area and matched for sex, age, smoking habits, educational level, and residence location...

OBJECTIVE: An increased prevalence of atherosclerosis has been shown among patients with hypopituitarism. The aim of the present study was to assess whether patients with hypopituitarism experience increased cardiovascular, in particular cerebrovascular, mortality. DESIGN AND PATIENTS: Retrospective cohort study of mortality, 1952-1992, in 344 patients, of whom 130 were female, receiving conventional hormone replacement for hypopituitarism following neurosurgery for pituitary tumours...
