Abstract

Background: Previous studies have noted a marked racial/ethnic difference in epidemiology and progression of diabetic nephropathy. The present study aims to examine the rate of decline in estimated GFR (eGFR) and factors associated with progression in a cohort of patients with DN in Sri Lanka.

 

Methods: A retrospective-cohort-study was conducted among patients with diabetic nephropathy. Data were collected retrospectively for 2-years by perusal of clinic records, including socio-demographic details, co-morbidities, investigational results, and details of medications. eGFR was calculated and staging was based on National Kidney Foundation Kidney Disease Outcomes Quality Initiative criterion.

 

Results: One hundred and fifty-five adults were included (men-20.3%). Mean age was 66.5±8.7 years. Mean duration of diabetes was 18.2±8.9 years, while diabetic retinopathy was the commonest microvascular complication (>90.0%). Majority were in either stage 3 (36.8%) or stage 4 (40.6%) CKD at recruitment. During the two-year period eGFR declined in 93 patients (60.0%), with a mean decline in eGFR of 5.2 ml/min/1.73m2 per year. There were 31 patients (20.0%) with rapid decline in eGFR (>5 ml/min/1.73m2 per year). Those with declining eGFR were significantly older (p<0.001). Decline in renal function was significantly associated with presence of albuminuria (OR:4.9; p<0.001).

 

Conclusion: A rapid decline in kidney function was observed in the present study population, with implications for negative long-term consequences for both the individual patients and the health care system. Therefore, it is an important factor that should be considered when taking policy decisions in relation to future preventive and curative health care planning.
