Abstract
PURPOSE: To evaluate the association between severity of hepatic steatosis/fibrosis with clinical, laboratory, and echocardiographic characteristics, including visceral obesity and type 2 diabetes mellitus (T2DM)-related micro- and macrovascular complications in diabetic patients with non-alcoholic fatty liver disease (NAFLD). METHODS: We studied 60 consecutive NAFLD outpatients with T2DM, recording several demographic and clinical characteristics, trunk and visceral fat, cardiac ultrasound, and micro- and macrovascular complications of diabetes mellitus including microalbuminuria, diabetic peripheral neuropathy, peripheral vascular disease, and cardiac autonomic function. Severity of steatosis and fibrosis was evaluated with abdominal ultrasound and liver stiffness measurements, respectively. RESULTS: Twenty-three (41%) of the patients had grade 1 steatosis and mean liver stiffness was 7.5 ± 3 kPa. After applying Bonferroni correction for multiple comparisons, ferritin concentration was the only factor significantly different between patients with mild (grade 1) compared to those with moderate/severe (grade 2/3) steatosis and showed good discriminative ability for the presence of moderate/severe steatosis (AUC: 0.74, sensitivity 88%, specificity 48%, PPV 74%, and NPV 72%). In addition, waist circumference was the only factor associated with the presence of significant fibrosis (≥ F2) with very good discriminative ability (AUC: 0.77, sensitivity 89%, specificity 45%, PPV 75%, and NPV 70%). CONCLUSION: Specific clinical and laboratory characteristics, which may be determined via widely accessible and noninvasive techniques, were associated with severity of diabetics NAFLD, taking into account echocardiographic characteristics, visceral obesity, and T2DM-related systemic complications.
