Summary Background Albuminuria is the standard biomarker for the diagnosis of diabetic nephropathy (DN). However, some patients with persistent microalbuminuria still progress to chronic kidney disease, raising the question of finding a better biomarker. This study aimed to evaluate the correlation of urinary liver-type fatty acid-binding protein (L-FABP) levels with renal function and to compare the role of urinary albumin-to-creatinine ratio (ACR) with urinary L-FABP in early detection of DN in type 2 diabetic patients. Methods The cross-sectional study was done on 106 type 2 diabetic patients and 30 non-diabetic people. L-FABP was measured with the Latex enhanced immunoturbidimetric technique. Results There was a strong and negative correlation between the urine L-FABP levels and eGFR (r = -0.606, p<0.001). The urinary L-FABP levels were significantly higher (p<0.001) in the normoalbuminuria diabetic group than the non-diabetic control group. The ROC-curve analyses in the diabetic patients and the normoalbuminuria diabetic patients showed that the AUCL-FABP was remarkably higher (p<0.001) than the AUCACR. An optimal cutoff value of 5 mg L-FABP/g Cr (with the sensitivity of 98.1% and specificity of 90%) and of 4.3 mg L-FABP/g Cr (with the sensitivity of 100% and specificity of 86.67%) was set to detect DN in the diabetic patients and the normoalbuminuria diabetic patients, respectively. Conclusions The change in urinary L-FABP levels happened earlier than in urinary albumin during renal function impairment. Urinary L-FABP can be used as a better indicator than ACR for early detection of DN in type 2 diabetes.

Abstract Background Diabetes mellitus (DM) is the most frequent cause of chronic kidney failure in both developed and developing countries. Diabetic nephropathy, is a clinical syndrome characterized by albuminuria (&gt;300 mg/day) with permanent and irreversible decrease in glomerular filtration rate (GFR). Aim of the Work To study the role of urinary TNF-α and urine KIM-1 in type 2 diabetic patients as predictors of DN comparative with albuminuria. Patients and Methods This is a cross-sectional study which include 90 type-2 diabetic patients and 30 controls selected from the outpatient clinic of Assiut University hospitals. All patients gave an informed consent and approval for the study was obtained from the IRB committee of the Assiut Medical Faculty. The recruited patients were divided into three groups: Normo-albuminuria Group (A) (n = 30): UACR less than 30 mg/gm, Microalbuminuria Group (B) (n = 30): UACR between 30-299 mg/gm and Macro-albuminuria Group (C) (n = 30): UACR equal or more than 300 mg/gm. Assess Urinary TNF-α and urine KIM-1 in comparision with albuminuria. Results Urinary KIM-1 and urinary TNF-α are statically significant with albuminuria in patients in the early stage of diabetic nephropathy (eGFR _60 mL/min/1.73 m2).Also there are statically significance between patients with macroalbuminuria than microalbuminuria. Conclusion The results of this study recommend the use of KIM-1 and TNF-α as good predictors of early detection of development of diabetic nephropathy.

Background: Microalbuminuria is one of the earliest markers of diabetic nephropathy, and if not recognized and treated early it may lead to diabetic nephropathy resulting in chronic renal failure. Aims and Objective: The aim of the current study was to find out the prevalence of microalbuminuria among newly detected Type 2 diabetic patients and also compare prevalence of microalbuminuria in patients with or without hypertension, dyslipidaemia and obesity. Materials and Methods: In this retrospective study, we analysed 90 patients with new onset type 2 diabetes mellitus. We divided the patients into two groups, group 1 with comorbidities like hypertension, dyslipidaemia and obesity (50 patients) and group 2 without comorbidities (40 patients). We analysed urinary microalbumin level in all patients and compared the prevalence of microalbuminuria between group 1 and group 2. Results: In our cohort of 90 patients, urinary microalbuminuria was found in 30 patients (33.3%). When we divided these nephropathy patients to group1 and group 2, we observed that group 1 with comorbidities had higher percentage of nephropathy patients i.e 24 out of 50(48%). Group 2 with 40 patients had only 6 patients with microalbiminuria ie 6 out of 40(15%). Incidence of microalbiminuria was higher in patients with hypertension, dyslipidaemia and obesity. Conclusions: We conclude that incidence of microalbiminuria is much more common in newly diagnosed type 2 diabetes. We also conclude that hypertension, obesity and hypercholesterolemia are risk factors for nephropathy and urinary microalbuminuria appears to be much more sensitive than serum creatinine as screening tool to detect diabetic nephropathy.
