[Analysis on associated risk factors and syndrome types in diabetes mellitus type 2 patients complicated with non-alcoholic fatty liver].

Objective: To explore the risk factors and the main TCM syndrome types associated with the diabetes mellitus type 2 (DM2) patients complicated with non-alcoholic fatty liver (FL).

Methods: Adopted controlled trial method, the age, stature, body weight, and body mass index (BMI) of 180 DM2 patients were compared with those complicated with or without FL. And some related laboratory indexes, including the age, stature, body weight, BMI, fasting blood glucose (FBG), C-peptide (CP), glycosylated hemoglobin (HbA1c), triglyceride (TG), total cholesterol (TC), high and low density lipoprotein cholesterol (HDL-C and LDL-C), and 2 h post-prandial CP (2 h CP), were compared as well. Moreover, patients' TCM syndrome types were classified.

Results: No significant differences were found between DM2 patients complicated with or without FL in aspects of FBG, HbA1c, TC, LDL-C and age, stature (P > 0.05), but significant difference did show between them in aspects of CP (4.09 +/- 2.40 microg/L vs 2.47 +/- 1.74 microg/L), 2h CP (6.38 +/- 5.46 microg/L vs 4.35 +/- 2.92 microg/L), TG (2.81 +/- 2.33 mmol/L vs 1.93 +/- 1.92 mmol/L), HDL-C (1.07 +/- 0.06 mmol/L vs 1.19 +/- 0.32 mmol/L) as well as in body weight (73.4 +/- 11.7 kg vs 61.4 +/- 10.1 kg) and BMI (26.0 +/- 3.67 vs 22.8 +/- 3.23), respectively (P < 0.05 or P < 0.01). Moreover, phlegm-dampness type was more liable to appear in DM2 patients complicated FL.

Conclusions: Obesity, insulin resistance and lipid metabolism disorder are the chief risk factors in DM2 patients complicated with FL and phlegm-dampness is the chief pathogenesis.
