Abstract

The study aims to assess the improvement in bone metabolism in prepubertal girls with Turner Syndrome (TS) after long-term polyethylene glycol recombinant human Growth Hormone (PEG-rhGH) treatment. A 12-month longitudinal prospective study was conducted with 28 prepubertal girls diagnosed with TS. Participants were divided into two groups: 18 received PEG-rhGH therapy (0.1–0.25 mg/kg/week) and 10 did not. Anthropometric measurements, bone turnover markers (BTMs), and serum levels of IGF-1, calcium, and phosphate were collected at baseline and after 12 months. BTMs included bone alkaline phosphatase (BAP), Type I collagen propeptide (CICP), Type I collagen telopeptide (CTX), and fibroblast growth factor 23 (FGF23). After 12 months of PEG-rhGH therapy, the treatment group showed significant increases in growth velocity (GV) and height standard deviation scores (HtSDS). Serum IGF-1 levels increased rapidly within one month and remained elevated. BTMs indicated enhanced bone formation, significantly increasing BAP and CICP, while CTX levels remained low. FGF23 levels initially rose slightly but declined below baseline by 12 months. Elevated blood phosphate levels were observed. PEG-rhGH therapy in children with TS significantly improves linear growth and enhances bone formation markers, benefiting bone metabolism.
