| Title: | Serum leptin level can be a negative marker of hepatocyte damage in nonalcoholic fatty liver. |
| Abstract: | BACKGROUND: The aim of this study was to determine whether leptin and insulin resistance (IR) showed differences between steatotic patients with and without elevated serum transaminases. METHODS: The study included 32 patients with fatty liver and high serum transaminase level (group I), 31 patients with fatty liver and normal serum transaminase level (group II), and 8 nonobese and nonsteatotic controls. The presence of steatosis was demonstrated by ultrasonography. Due to the effect of body mass index (BMI) on leptin levels, groups I and II were divided to form four subgroups for analysis (group IA, BMI <or=30; group IB, BMI >30; group IIA, BMI <or=30; and group IIB, BMI >30. RESULTS: The serum leptin levels in group IIB were significantly higher than the levels in group IB ( P = 0.017). Serum leptin was also higher in group IIA than in group IA, but this difference was not statistically significant ( P = 0.097). Logistic regression analysis revealed a significant negative correlation between serum leptin level and the presence of a high transaminase level (odds ratio, 0.97; 95% confidence interval, 0.95-0.99). The levels of IR in the four patient groups were comparable, but the controls had significantly lower IR levels than group IIA. CONCLUSIONS: Elevated serum leptin seems to be a feature of steatotic patients with normal transaminase levels, and the level of serum leptin seems to decrease as the hepatocyte injury develops. IR is a common feature of fatty liver disease, irrespective of the presence of hepatocellular necrosis. |
