Perbedaan Kadar Liver Fatty Acid Binding Protein (L-FABP) Urine Penderita Diabetes Melitus Tipe 2 dengan Normoalbuminuria dan Mikroalbuminuria

Diabetes mellitus (DM) is the leading cause of the end stage renal disease (ESRD). Around 20−40% patients with DM develop diabetic nephropathy and eventually progress into ESRD. Type 2 DM has a greater prevalence to develop diabetic nephropathy. Oxidative stress accumulation can increase permeability of the glomerulus which results in increased urine albumin excretion, which is divided into three groups: normoalbuminuria, microalbuminuria and macroalbuminuria. Glomerulus dysfunction occurs after tubulointerstisial renal dysfunction which decreases peritubular capillary flow that leads to tubulointerstisial hypoxia. Liver fatty acid binding protein function is to reduce hypoxia by binding oxidative stress and excretes it into urine. The aim of this study was to analyze the differences in the urine L-FABP level between normoalbuminuria and microalbuminuria type 2 DM patients. The study design was observational analytic using cross-sectional method. Subjects were 70 DM type 2 patients with normoalbuminuria (38 patients) and microalbuminuria (32 patients). Statistical analysis was performed using the Mann Whitney test The results found that there were significant differences in levels of urine L-FABP between normoalbuminuria and microalbuminuria type 2 DM patients (ZM-W=3.513, p
