[Associated risk factors of fatty liver in the patients with type 2 diabetes mellitus].
OBJECTIVE
To analyze the associated risk factors, clinical characteristics and laboratory abnormalities of type 2 diabetes patients with fatty liver.


METHODS
The data of type 2 diabetes cases with fatty liver were collected in our hospital. 63 cases of type 2 diabetes without fatty liver were selected randomly as control during the same period. The associated variables were analyzed by using logistic regression model. The clinical data and liver function were compared between two groups.


RESULTS
The proportion of obesity and hyperlipidemia was higher in type 2 diabetes patients with fatty liver than without fatty liver. Body mass index (BMI) (OR: 4.392) was positive correlation to fatty liver in the patients with type 2 diabetes. In contrast, insulin sensitivity index (ISI) (OR: 0.000) and regular insulin treatment (OR: 0.058) were negative correlation to it. The abnormal frequencies of aspartate aminotransferase (AST, 16.0%), alanine aminotransferase (ALT, 25.2%), the ratio of AST/ALT less than 1 (52.8%) and gamma-glutamyltransferase (GGT, 31.9%) of type 2 diabetes patients with fatty liver were significantly higher than those without fatty liver (3.2%, 6.4%, 36.5% and 11.1% respectively).


CONCLUSIONS
Obesity and insulin resistance might increase the risk of fatty liver in the patients with type 2 diabetes. Patients of type 2 diabetes with fatty liver show higher serum lipid level and more obvious damages of liver function than those without fatty liver
