Prevalence of chronic kidney disease in South Asia: a systematic review

Abstract

BackgroundChronic kidney disease (CKD) is becoming a major public health problem around the world. But the prevalence has not been reported in South Asian region as a whole. This study aimed to systematically review the existing data from population based studies in this region to bridge this gap.MethodsArticles published and reported prevalence of CKD according to K/DOQI practice guideline in eight South Asian countries between December 1955 and April 2017 were searched, screened and evaluated from seven electronic databases using the PRISMA checklist. CKD was defined as creatinine clearance (CrCl) or GFR less than 60 ml/min/1.73 m2.ResultsSixteen population-based studies were found from four South Asian countries (India, Bangladesh, Pakistan and Nepal) that used eGFR to measure CKD. No study was available from Sri Lanka, Maldives, Bhutan and Afghanistan. Number of participants ranged from 301 in Pakistan to 12,271 in India. Majority of the studies focused solely on urban population. Different studies used different equations for measuring eGFR. The prevalence of CKD ranged from 10.6% in Nepal to 23.3% in Pakistan using MDRD equation. This prevalence was higher among older age group people. Equal number of studies reported high prevalence among male and female each.ConclusionsThis systematic review reported high prevalence of CKD in South Asian countries. The findings of this study will help pertinent stakeholders to prepare suitable policy and effective public health intervention in order to reduce the burden of this deadly disease in the most densely populated share of the globe.Electronic supplementary materialThe online version of this article (10.1186/s12882-018-1072-5) contains supplementary material, which is available to authorized users.

Chronic Kidney Diseases and Acute Kidney Injury in Patients With COVID-19: Evidence From a Meta-Analysis

“…Several reasons are urging us to emphasize the importance of CKD during the COVID-19 infection. First, CKD has not attracted enough awareness due to its inconspicuous course, especially in the early stage (13,15,64). Second, diabetes and hypertension are the leading causes of CKD in all developed countries and many developing countries, and the long-term or advanced CKD usually increases the risk of cardiovascular diseases (13,65).…”

Prevalence of Chronic Kidney Disease Among Community Remote Areas in Sabah: Population-Based Study

“…CKD is defined by using the Modification of Diet in Renal Disease (MDRD) equation together with CKD-EPI. 6 In South Korea, Taiwan, and Thailand. CKD was defined by using the MDRD equation with eGFR< 60 ml/min per 1.73m 2 .…”
