Long-acting growth hormone for treating growth hormone deficiency in children: a meta-analysis of randomized controlled trials focusing on changes in body mass index

Resumo original em inglês

O que aconteceu

The purpose of this study is to compare the effect of long-acting growth hormone (LAGH) to daily GH on body mass index (BMI) in children with growth hormone deficiency (GHD).

We searched the PubMed database from its inception to July 2025 and identified three relevant randomized controlled trials lasting over 6 months, with extension phases providing longitudinal BMI data. Longitudinal BMI data were available for lonapegsomatropin, somatrogon, and somapacitan, but not for polyethylene glycol LAGH.

O que encontraram

A total of 585 patients were included in the present analysis, of which 346 were in the LAGH group, and 239 were in the daily rhGH group, derived from seven original articles and two abstracts/ePosters. At 12 months, there was a significant difference in BMI SD scores between LAGH and daily GH groups (Mean difference [MD] 0.66 SDS [95% confidence interval [CI] 0.04-1.29]). BMI SDS significantly increased in the LAGH group (MD + 0.41 SDS [95% CI 0.04-0.77] from 0 to 12 months), whereas it did not change in the daily GH group (MD -0.35 SDS [95% CI -0.76 to +0.07] from 0 to 12 months). Between 12 and 24 months, after switching from daily GH to LAGH (daily GH/LAGH), or pursuing LAGH (LAGH/LAGH) in the extension phases of the studies, BMI SDS significantly increased in the daily GH/LAGH switching group (MD + 0.75 SDS [95% CI 0.24-1.27] from 12 to 24 months), whereas it remained steady in the LAGH/LAGH group. Omitting one study at a time from the meta-analysis did not materially affect the results.

Por que isso importa

An increase in body mass index SD score is associated with the first year of LAGH use.
