Profile of chronic kidney disease from a nephrology underserviced region in North Eastern India: a preliminary report from a single center in Assam.

Abstract

Chronic kidney disease (CKD) is a worldwide health problem affecting at least 10% of the world's population. CKD represents especially a large burden in low- to middle-income countries that are ill equipped to deal with its consequences. The burden of CKD is increasing in India as well. Although diabetes and hypertension account for much of this burden of CKD, there are regions where a surprisingly high rate of CKD of undetermined etiology (CKD-U) has been described in certain areas of the country. In our observational cross-sectional study, we attempted to look at burden and etiology of CKD in a predominantly rural referral center. Out of 334 patients with diagnosed CKD, of whom 70% were male, included from Oct 2021 to July 2022, CKD-U was the single largest cause of CKD in 154 (46.1%) followed by diabetic nephropathy in 148 (44.3%). 80% of CKD patients presented initially with advanced CKD (stages 4 and 5). Approximately, 2/3rd of CKD patients reported a family income of less than 10,000 Rs/month (< 130USD). Hypertension was seen in 89% of patients in total (73% in CKD-U vs. 100% in other cause CKD). Our initial study brings to focus another new and as yet unrecognized hotspot for CKD-U in the Indian subcontinent. Given the vast diversity in the population in this region and variable delivery health care resources, we believe that concerted efforts should be made by governmental and other agencies to better understand the nature of this undiagnosed CKD epidemic so that adequate preventative strategies can be envisaged.
