Clinical characters of different degrees nonalcoholic fatty liver and the relationships with blood uric acid / 中国综合临床

ABSTRACT

Objective To analyze the clinical characters of the different degrees nonalcoholic fatty liver (NAFLD) and the relationships with blood uric acid.Methods Two hundred and eighty-two cases body examinational and hospitalized patients were selected.According to whether complicated with NAFLD and liver steatosis degree,patients were divided into 4 Groups.Group A was control group that without NAFLD,Group B was mild NAFLD group,Group C was moderate NAFLD group and Group D was severe NAFLD group.Clinical data,blood lipids,blood uric acid and other biochemical indicators of four groups were compared.Results In 282 cases of patients,there were 78 cases (27.66％) without NAFLD patients,94 cases (33.33％) mild NAFLD,92 cases (32.62％) moderate NAFLD and 18 cases (6.38％) severe NAFLD.As the severity of fatty liver increased,body mass index (BMI) higher and higher ((24.51 ± 2.55),(27.06± 2.81),(28.37± 3.23),(30.71 ± 2.96) kg/m2),and the differences among four groups were statistically significant (F =35.976,P ＜0.05).Gglycerin trilaurate (TG),low density lipoprotein cholesterol (LDL-C) of D group were hihger than other groups ((3.04± 1.22) mmol/L vs.(1.73± 1.46),(2.59 ± 1.78),(2.81 ± 1.94) mmol/L,(2.99± 0.52) mmol/L vs.(2.28±0.78),(2.47±0.75),(2.41±0.74) mmol/L),high density lipoprotein cholesterol (HDL-C) was lower compared with group A,B,C (1.00± 0.23) mmol/L vs.(1.15± 0.24),(1.05± 0.21),(1.00 ±0.21) mmol/L),the differences were statistically significant(F=6.818,4.597,6.414;P＜0.05).In 4 groups the blood uric acid(UA) of groups B,C,D was higher than group A,group D was higher than group B,C,and the differences were statistically significant((316.13±71.86),(356.98±83.00),(355.37±81.01),(409.67 ±50.90) μmol/L;F=8.797;P＜0.05).Conclnsion Obese patients are more susceptible to NAFLD,and NAFLD with a certain degree of lipid and uric acid metabolism,and the severity of NAFLD has a positive correlations with lipids and serum uric acid levels.It is particularly obvious in patients with severe NAFLD,which prompting that blood uric acid level can be used as an independent risk factor in the pathogenesis of NAFLD,and as an auxiliary judge for NAFLD severity index.
