A study of the Relationship between Serum Sialic Acid and urine microalbumin in Patients of Type 2 Diabetes Mellitus Nephropathy
Abstract
Background and Aim: Laboratory assessment of sialic acid as a marker of microvascular complications can be a diagnostic tool for diabetes mellitus. Microalbumin is an established predictor of diabetic nephropathy. The study was undertaken to evaluate serum sialic acid and microalbumin levels and to correlate it with glycemic control in diabetic nephropathy patients. Material and Methods: Clinically diagnosed diabetic nephropathy patientsvisiting the medicine OPD (outdoor patient department) and NCD (Non-Communicable Disease) were selected for the study. This study included 75 subjectswith diabetes types 2 of which 44 were males and 31were females. Control includes a total of 75 out of which 49 Males and 26 females. Blood samples were analysed for the glucose, C-reactive protein, and sialic acid. Urine sample was analyzed for microalbumin and sialic acid. Results: The mean value of FBS was 161±53.2 mg/dl which was significantlyhigher than controls 81±5.2. The Sialic acid in subjects was 105±21 mg/dl which is higher than controls 51±6 mg/dl. The urine microalbumin level was found to be 96.5±17.2 in subjects, whereas 6.4±1.6 mg/dl was in controls. Serum Creatinine level in subjects was 8.75±2.05 mg/dl which was higher than subjects 0.8±0.3mg/dl. Serum Urea in diabetic nephropathy subjects was 93.5±15.4 mg/dl, which is positively higher than controls 30.8±7.1 mg/dl. Conclusion: Urine microalbumin is established as a potential marker for diabetic nephropathy. The correlation of serum sialic acid, urine microalbumin and serum creatinine proposed serum sialic acid as an accessory diagnostic marker for diabetic nephropathy. Estimation of sialic acid before microalbumin in diabetic patients helps assess glycemic control and identify the risk for nephropathy and other secondary complications of diabetes mellitus, which are the main causes of mortality and morbidity among type-2 diabetes mellitus patients.
