Abstract
Purpose
Polycystic ovarian syndrome (PCOS) is a complex and not fully elucidated pathology. This prevalent endocrinopathy affects patients in reproductive age, impacts on estrogen-dependent diseases, as well as in infertility. In this context, Kisspeptin (KP) may be considered a potential biomarker for PCOS diagnosis and follow-up. Here, we aimed to verify the levels of KP in obese and non-obese patients with PCOS, their relationship with other hormones, in comparison to healthy controls.
Methods
A systematic review and meta-analysis were performed according to the PRISMA guidelines. We searched MEDLINE, EMBASE, PsycINFO, Global Health, The Cochrane Library, Health Technology Assessment Database, and Web of Science for eligible studies. A random effects model meta-analysis of standardized mean difference (SMD) was conducted and the I2 was used to assess heterogeneity. Meta-regression was conducted through mixed-effects model.
Results
A total of 12 studies were included, comprising 660 PCOS patients and 600 controls. The KP levels were lower in the control group (0.76: 0.17–1.35; 95% CI). In the subgroup analyses, patients were divided in non-overweight/obese (BMI < 25) and overweight/obese (BMI ≥ 25) groups. The meta-regression revealed a difference between the obese and non-obese groups (z = 2.81; p = 0.0050).
Conclusions
PCOS patients showed higher KP levels than control, and obese non-PCOS patients also showed altered KP levels. All studies had poor descriptions of sample collection, pre-analytical and analytical procedures, which is critical considering structural characteristics of the KP molecule.
