Abstract

Acromegaly is a chronic disease characterized by the elevated growth hormone (GH) and insulin-like growth factor-1 (IGF-1) levels. Treatment options for acromegaly are surgery, radiotherapy and medical treatments. Somatostatin analogues, dopamine agonists and pegvisomant are the options for medical treatment. Pegvisomant is a GH receptor antagonist that shows its effect by blocking GH receptor dimerization and the intracellular pathways required for the release of IGF-1. Pegvisomant is used as a third line treatment option, if biochemical improvement cannot be achieved despite surgery and maximum doses of other medical treatments. In this review, we will present acromegaly patients who recieved pegvisomant in our clinic, in light of the current literature

Abstract

Akromegali, artmış büyüme hormonu (BH) sekresyonu ve artmış insülin benzeri büyüme hormonu-1 (IGF-1) seviyeleri ile karakterize kronik bir hastalıktır. Akromegalide tedavi seçenekleri cerrahi, radyoterapi ve medikal tedavidir. Medikal tedavide somatostatin analogları, dopamin agonistleri ve pegvisomant kullanılmaktadır. Pegvisomant, büyüme hormonu reseptör antagonisti olup etkisini reseptör dimerizasyonunun engellenmesi ile birlikte IGF-1 salınımı için gerekli intraselüler yolakları engelleyerek gösterir. Cerrahi ve maksimum doz ve kombinasyonda medikal tedaviye rağmen biyokimyasal yanıt sağlanamayan hastalarda üçüncü basamak tedavide kullanılır. Bu derlemede, akromegali tedavisinde diğer seçeneklere göre nispeten yeni olan pegvisomant tedavisi kliniğimizdeki tedavi sonuçlarımız ile birlikte güncel literatür ışığında tekrar gözden geçirilmiştir.
