Abstract:
Objective To study the effect of serum leptin in “two hits” of nonalcoholic fatty liver disease (NAFLD).Methods Fasting serum leptin(LEP) ,malondialdehyde(MDA) ,hyaluronic- acid(HA) ,type Ⅲ procollagen ( PCⅢ), laminin ( LN), and type Ⅳ collagen ( Ⅳ-C ) were detected in 43 simple nonalcoholic fatty liver( NAFL ) patients ,41 NASH patients and 40 healthy subjects. Insulin resistance was estimated by HOMA value and its relatio nship with leptin level in NAFLD was analyzed. The severity of lipid peroxidation was estimated by MDA and its relationship with leptin level in NAFLD was analyzed. The relationship of serum fibrosis markers with leptin level in NAFLD also was analyzed. Results Serum leptin, HOMA value in NAFLD were higher than those of healthy controis. MDA,PC Ⅲ 、Ⅳ-C 、LN 、HA in NASH were higher than those of healthy controls or simple NAFL patients. ,HOMA value, in NAFLD positively correlated with leptin. MDA, PC Ⅲ、 Ⅳ-C 、LN、HA in NASH positively correlated with leptin. Conclusion Serum leptin closely correlated with insulin resistance which results in “First hit” of NAFLD. There was certain relationship of leptin with “Second hit” of NAFLD. Leptin should be one of the factors which result in liver fibrosis.
