Abstract
To identify distinct patterns of insulin-like growth factor-1 (IGF-1) and insulin-like growth factor-binding protein 3 (IGFBP-3) in girls with central precocious puberty (CPP), and to compare IGF-1 and IGFBP-3 levels in patients with CPP and precocious thelarche (PT).
A literature search of PubMed, Embase, and Scopus databases was done to identify observational studies. Newcastle-Ottawa Scale (NOS) was used to assess the quality of the studies. Pooled weighted mean difference (WMD) and 95% confidence intervals (CI) were reported.
Fourteen studies were included. As opposed to age-matched or similar-aged pre-pubertal girls, patients with CPP had significantly higher levels of IGF-1 and IGFBP-3. CPP was associated with higher levels of IGF-1 approaching statistical significance but similar levels of IGFBP-3 compared to PT.
Distinct hormonal patterns, such as elevated IGF-1 and IGFBP-3, were identified in patients with CPP, suggesting a potential diagnostic value of IGF-1 and IGFBP-3 levels.
期刊介绍：
Growth Factors is an international and interdisciplinary vehicle publishing new knowledge and findings on the regulators of cell proliferation, differentiation and survival. The Journal will publish research papers, short communications and reviews on current developments in cell biology, biochemistry, physiology or pharmacology of growth factors, cytokines or hormones which improve our understanding of biology or medicine. Among the various fields of study topics of particular interest include: •Stem cell biology •Growth factor physiology •Structure-activity relationships •Drug development studies •Clinical applications
