Abstract:
Objective To analysis the risk factors for elevated ALT level in patients with Non-alcoholic fatty liver diseases (NAFLD).Method Fifty-six (male 25,female 31) NAFLD patients with elevated ALT and 153 NAFLD patients (male 64,female 89) with normal ALT and 160 (male 80,female 80) health subjects were selected.ALT was detected by rate assay,total cholesterol (TC),triglycerides (TG),low-density lipoprotein cholesterols (LDL-C),high-density cholesterol (HDL-C) and uric acid (UA) were detected by enzymatic method.Free fatty acid (FFA) was detected by immunoturbidimetry assay.Spearman correlation was used to analysis the relation between ALT and TC,TG,LDL-C,HDL-C,UA and FFA.Logistic regression was used to analyses the risk factor for elevated ALT level.Results TC,TG,LDL-C,UA and FFA levels were significantly higher in NAFLD group (including normal ALT group and elevated ALT group) than those in health group no matter male and female,HDL-C was significantly lower in these two groups when compared to control group,but binary logistic regression and spearman analysis showed that only UA and FFA were the risk factors for elevated ALT level and significantly positively correlated with ALT level,abnormal UA and FFA for male were associated with 3.96-fold(95CI％ =1.40～ 11.22,P=0.010) and 3.27-fold (95 ％ CI =1.14 ～ 9.40,P =0.028) of increased risk of elevated ALT level respectinely,correlation coefficient were 0.40(P=0.000),0.29(P=0.006),Meanwhile Exp(B) of elevated ALT level for female with abnormal UA,FFA were 4.49 (95CI％=1.79～11.28,P=0.001) and 3.17 (95CI％ =1.25～8.04,P=0.015),correlation coefficient were 0.34 (P =0.000),0.27 (P =0.003).Conclusion Elevated ALT level was not associated with dyslipidemias,but related to UA and FFA.They can be used as candidate markers for predicting severity of liver damage.
