A considerable number of studies have shown that plasma concentrations of FABP4 is increased in obesity and T2DM, and that circulating FABP4 levels are correlated with certain clinical parameters, such as body mass index, insulin resistance, and dyslipidemia.
The aim of the study was to determine circulating levels of fatty acid binding protein 4 (FABP-4) in a cohort of HIV-1-infected patients treated with combination antiretroviral therapy (cART) and to investigate the relationships between FABP-4 levels and insulin resistance, dyslipidaemia, lipodystrophy and levels of proinflammatory adipocytokines in these patients.
In conclusion, FABP4 plasma concentrations hold strong potential for development as a clinical biomarker for atherogenic dyslipidemia, independent of obesity and insulin resistance, in type 2 diabetic subjects.
