ABSTRACT

Objective To explorethe influence of leptin on the onset of puberty, and to study the relationship between leptin and hormones relevant to gonadal axis and its effect on idiopathic central precocious puberty (ICPP) in obese girls. Methods Fifty-six girls with ICPP fulfilled the current diagnostic criteria and came from pediatric endocrinology clinic. The 56 cases were divided into 2 groups according to whether there was obesity or not 38 non-obese girls with ICPP and 18 obese girls with ICPP. Forty-three age-matched prepubertal girls were divided into non-obese prepuberty group (25 girls) and obese prepuberty group (18 girls). Serum leptin wasassayedwithELISA,andserum FSH, LH and E 2 were determined with immunochemiluminescent. Results As compared with non-obese prepuberty group [(4.1?1.5)?g/L], the leptin concentrations in obese ICPP group [(14.7?7.5)?g/L], non-obese ICPP group [(8.8?5.1)?g/L] and obese prepuberty group [(8.0?5.3)?g/L] were significantly higher (P
