Background
The association between serum alanine aminotransferase (ALT) levels and hepatic insulin resistance (IR) has been evaluated with the hyperinsulinemic-euglycemic clamp. However, there is no information about the association of ALT with the Hepatic Insulin Resistance Index (HIRI). The aim of this study was to evaluate the association between serum ALT levels and HIRI in subjects with differing degrees of impaired glucose metabolism.Methods
This cross-sectional study included subjects that had an indication for testing for type 2 diabetes mellitus (T2DM) with an oral glucose tolerance test (OGTT). Clinical and biochemical evaluations were carried out including serum ALT level quantification. HIRI was calculated for each participant. Correlation analyses and lineal regression models were used to evaluate the association between ALT levels and HIRI.Results
A total of 324 subjects (37.6% male) were included. The mean age was 40.4?±?14.3?years and the mean body mass index (BMI) was 32.0?±?7.3?kg/m2. Individuals were divided into 1 of 5 groups: without metabolic abnormalities (n?=?113, 34.8%); with the metabolic syndrome (MetS, n?=?179, 55.2%), impaired fasting glucose (IFG, n?=?85, 26.2%); impaired glucose tolerance (IGT, n?=?91, 28.0%), and T2DM (n?=?23, 7.0%). The ALT (p?ConclusionsALT levels are independently associated with HIRI in subjects with the MetS, IFG, IGT, and T2DM. The ALT value in these subjects may be an indirect parameter to evaluate hepatic IR.
