Prediction of NAFLD occurrence in prediabetes patients.

Non-alcoholic fatty liver disease (NAFLD) is a component of metabolic syndrome that significantly increases the cardiovascular risk of patients with glucose metabolism alterations. This study identified the prevalence of NAFLD, predictors of NAFLD and explored the link between insulin sensitivity, insulin resistance and leptinemia in 143 patients registered with prediabetes. Abdominal ultrasound was performed, and fasting insulin, postprandial insulin, leptin levels, common clinical/biochemical determinations were assessed. Certain variables that can predict NAFLD existence were determined and it was found that there is a high prevalence of NAFLD in patients with prediabetes. In univariate analysis, statistically significant associations (P<0.05) were found between waist circumference, systolic blood pressure, diastolic blood pressure, triglycerides, HDL-cholesterol, insulin sensitivity, β-cell function, leptin and NAFLD presence. The coefficients for the variables which obtain statistically significant association (P<0.05) are low, except for leptin which is the biochemical parameter that (in both univariate and multivariate analysis) is a strong predictor of NAFLD presence.
