Pre-treatment IGF-I concentrations predict radiographic osteoarthritis in acromegalic patients with long-term cured disease

Biermasz Nienke R , Wassenaar Moniek J E , van der Klaauw Agatha A , Pereira Alberto M , Smit Johannes W A , Roelfsema Ferdinand , Wolterbeek Ron , Kroon Herman M , Kloppenburg Margreet , Romijn Johannes A

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...

Joustra Sjoerd D , Roelfsema Ferdinand , Endert Erik , van Trotsenburg ASPaul , Fliers Eric , Schneider Harald J , Kosilek Robert P , Kroon Herman M , Logan John , Turgeon Marc-Olivier , Zhou Xiang , Toufaily Chirine , Koulouri Olympia , Gurnell Mark , Bassett JHDuncan , Williams Graham R , Oostdijk Wilma , Wit Jan-Maarten , Pereira Alberto M , Biermasz Nienke R , Bernard Dan J , Schoenmakers Nadia

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...
