Abstract

Diabetic nephropathy predominantly starts with abnormal glomerular permeability, the primary step towards the glomerulosclerosis, when plasma molecules cross the glomerular basement membrane (GBM) and subsequently appear in the urine. The progression rate of glomerulosclerosis is proportionate to abundance and severity of lesions created at incipient stage, which is reflected as proteinuria even though eGFR remains in the normal range. Our study of 683 type 2 diabetic patients with varying degree of protenuriahas shown the excessive glycation inducedprotenuriaand increased urinary IgG excretion with the progression of glomerular injury. Type 2 diabetic patients were selected for this study with eGFR75 l/min/1.73 m2 and grouped into four quartiles based on urinary IgG creatinine ratio (UIgGCR). The markers of key factors affecting progression of proteinuria were estimated through biochemical tests. The impact of these markers on proteinuria was accessed by applying multinomial logistic regression. The adjusted odds ratio for the urinary glycosaminoglycanscreatinine ratio (UGAGCR) was 1.186 (95 % CI: 1.061-1.327) P\0.003 in highest quartiles of UIgGCR, followed by odds ratio for markers of collagen catabolism 1.051 (95 % CI: 1.025-1.079) P\0.001, and urinary sialic acid creatinine ratio (USACR) 1.044 (95 % CI: 1.013-1.077) P\0.006 respectively. The marker of glycation, i.e., glycated hemoglobin showed the highest odds ratio 5.449 (95 % CI: 1.132-26.236) P\0.035. In addition, odds for the systolic blood pressure was observed 1.387 (95 % CI: 1.124-1.712) P\0.002. The higher odds inform and could help to discriminate the diabetic patients with fast progressive diabetic nephropathy. The study describes critical relationship between the urinary excretion of IgG and factors leading to proteinuria in type 2 diabetic patients.
