Growth hormone deficiency (GHD) can occur after treatment for acromegaly. It is unclear whether treatment with recombinant human growth hormone (rhGH) in these patients is beneficial. Patients were randomized to either 1 year of rhGH replacement (n=10) or placebo followed by rhGH replacement for 1 year (delayed rhGH treatment, n=6). Sixteen patients (8 men, mean age 56 years) with GHD after treatment for acromegaly were studied. Study parameters were assessed at ...

Context: Loss-of-function of immunoglobulin superfamily 1 (IGSF1) causes an X-linked syndrome of central hypothyroidism, macroorchidism, and variable prolactin deficiency, GH deficiency in childhood, delayed pubertal testosterone rise, and/or obesity. The clinical features advert towards a pivotal role for IGSF1 in the pituitary gland, but detailed knowledge on pituitary hormone secretion in this syndrome is lacking.Objective: To study detailed ...

Background: Hypopituitarism after traumatic brain injury (TBI) is considered to be a prevalent condition, and may affect quality of life (QoL) and cognitive function. However, the prevalence of hypopituitarism differs considerably among reported studies due to differences in definitions, endocrine assessments of hypopituitarism, and confounding factors, like timing of evaluation and the severity of the trauma.Aim: To evaluate the prevalence of hypopituit...

Objective: To identify factors influencing the development of osteoarthritis during long-term control of acromegaly, focusing on disease specific parameters, growth hormone (GH) and insulin-like growth factor I (IGF-I) concentrations and duration of disease, adjusted for the well-known determinants of primary osteoarthritis.Design: Follow-up study.Methods: We studied 67 patients, with adequate biochemical control of acromegaly for ...

Objective: To evaluate the impact of the genomic deletion of exon 3 in the growth hormone receptor (d3GHR) on co-morbidities of acromegaly in a well-characterized cohort of patients with long-term remission of acromegaly.Design: Cross sectional study.Methods: The presence of the d3GHR polymorphism was assessed in 86 acromegalic patients and related to clinical outcome, i.e. anthropometric parameters, osteoarthritis, and the metabol...

X-linked IGSF1 (immunoglobulin superfamily, member 1) loss-of-function mutations in males are associated with central hypothyroidism, macroorchidism, and a variable spectrum of anterior pituitary dysfunction. Igsf1 deficient male mice also exhibit central hypothyroidism, however, the physiological and molecular function of IGSF1 in both species has not yet been elucidated. Although partial transient GH deficiency is a ra...
