Chronic kidney disease of unknown aetiologies (CKDu) is increasingly recognized in tropical regions and is now considered a global health problem. A detailed hydrogeochemical investigation has been performed in three CKDu hotspots in Sri Lanka to assess the geo-environmental aetiological factors influencing this disease. A total of 71 ground- and 26 surface water samples were collected from Girandurukotte, Wilgamuwa and Nikawewa regions and analysed for major constituents and trace elements. The affected regions are dominated by Ca-Mg-HCO3 facies groundwater that is mainly controlled by silicate weathering...

Chronic kidney disease of unknown etiology (CKDu) is the main health issue in the dry zone of Sri Lanka. Despite many studies carried out, causative factors have not been identified yet clearly. According to the multidisciplinary researches carried out so far, potable water is considered as the main causative factor for CKDu. Hence, the present study was carried out with combined isotopic and chemical methods to understand possible relationships between groundwater; the main drinking water source, and CKDu in four endemic areas in the dry zone...

Leptospirosis is the most prevalent zoonosis affecting more than 1 million populations worldwide. Interestingly, leptospirosis endemic regions coincide with chronic kidney disease (CKD) hotspots largely due to flooding and agricultural overlaps. Acute leptospirosis induces multiple organ dysfunction including acute kidney injury and may predispose to CKD and end-stage renal disease, if not treated timely. Asymptomatic infection may carry the bacteria in the kidney and CKD progresses insidiously. Histologic finding of leptospirosis renal disease includes tubulointerstitial nephritis, interstitial fibrosis, and tubular atrophy...

High incidence of chronic kidney disease of unknown etiology (CKDU) prevalent in many countries (e.g., Sri Lanka, equatorial America) is reviewed in the context of recent experimental work and using our understanding of the hydration of ions and proteins. Qualitative considerations based on Hofmeister-type action of these ions, as well as quantitative electrochemical models for the Gibbs free energy change for ionpair formation, are used to explain why (1) fluoride and water hardness due to magnesium ions (but not due to calcium ions) and similarly (2) cadmium ions in the presence of suitable pairing ions can be expected to be more nephrotoxic, while arsenite in the presence of fluoride and hardness may be expected to be less nephrotoxic...

BACKGROUND: Globally, chronic kidney disease of unknown aetiology (CKDu) is observed in several areas and among specific ethnic or occupational groups. Given the widespread environmental pollution and the proportions of agriculture workers world-wide, CKDu may be the next global public health issue demanding attention. Recent escalation of CKDu in Sri Lanka has caused a serious public health crisis in the country, made worse by lack of national data. MAIN TEXT: The specific geographic distribution, preponderance among farming population, similar histology findings and absence of usual risk factors for kidney disease indicate undetected nephrotoxic agents playing a role in causation...

The main causes of chronic kidney disease (CKD) globally are diabetes and hypertension but epidemics of chronic kidney disease of unknown etiology (CKDu) occur in Central America, Sri Lanka, India and beyond. Althoug also being observed in women, CKDu concentrates among men in agricultural sectors. Therefore, suspicions fell initially on pesticide exposure, but currently chronic heat stress and dehydration are considered key etiologic factors. Responding to persistent community and scientific concerns about the role of pesticides, we performed a systematic review of epidemiologic studies that addressed associations between any indicator of pesticide exposure and any outcome measure of CKD...

In this article, I examine the crucial role of the biomedical industry, epidemiological and biomedical research, and the media in forming attitudes to and the understanding of chronic kidney disease of unknown etiology (CKDu) in Sri Lanka. Local conceptions of CKDu have been shaped by the circulation in the media of epidemiological research findings pertaining to the disease, biomedical interventions in the management of the disease in hospitals and clinics, community programs involving mass blood surveys and the testing of well water, and local food and health education programs carried out through village health committees...

AIM: Environmental toxin/s is alleged to be the contributory factor for the chronic kidney disease of unknown etiology (CKDu) in Sri Lanka. The potential of drinking water as a medium for the nephrotoxic agents in the affected subjects has been comprehensively discoursed in the recent past. The present study was aimed to assess the effect of replacing the habitual drinking water on the kidney function of CKDu patients residing in the North Central Province of Sri Lanka: METHODS: An interventional study was carried out to assess the disease progression rate of a CKDu population whose habitual drinking water was replaced by bottled spring water certified by Sri Lanka Standard (SLS) for a period of 18 month along with a population of CKDu patients who continued with their usual drinking water...

There have been several global epidemics of chronic kidney disease of unknown etiology (CKDu). Some, such as Itai-Itai disease in Japan and Balkan endemic nephropathy, have been explained, whereas the etiology of others remains unclear. In countries such as Sri Lanka, El Salvador, Nicaragua, and India, CKDu is a major public health problem and causes significant morbidity and mortality. Despite their geographical separation, however, there are striking similarities between these endemic nephropathies. Young male agricultural workers who perform strenuous labor in extreme conditions are the worst affected...

Chronic-Kidney-Disease of Unknown-etiology (CKDu) has been reported in developing-countries like Sri-Lanka, India and Central-America without sparing the Indian sub-district (namely Canacona) located in south-Goa. The disease etiology is unlinked to common causes of diabetes and hypertension and assumed to be environmentally induced due to its asymptomatic-nature and occurrence in groundwater relying communities. This study aimed to understand environmental risk-factors underlying CKDu-etiology using Indian sub-district (Canacona) as case-study...

Research published on Chronic Kidney Disease of Unknown Etiology (CKDu) in Sri Lanka has been undertaken largely from biomedical and epidemiological perspectives. The main objective of these studies has been to identify the etiology of the disease, which affects as much as 15-21% of the population in some regions and is associated with kidney failure. Few studies have sought to address how CKDu is socially and behaviorally situated in the affected districts. The present study, informed by structural violence theory, utilized a mixed-method approach that analyzed primary and secondary data for Medawachchiya District Secretariat Division in Anuradhapura District for 2010 and 2015, and examined CKDu as a manifestation of social inequality and exclusion and the creation of a marginalized group of agricultural laborers...

BACKGROUND: In Sri Lanka, there exists chronic kidney disease of both known (CKD) and unknown etiologies (CKDu). Identification of novel biomarkers that are customized to the specific causative factors would lead to early diagnosis and clearer prognosis of the diseases. This study aimed to find genetic biomarkers in blood to distinguish and identify CKDu from CKD as well as healthy populations from CKDu endemic and non-endemic areas of Sri Lanka. METHODS: The expression patterns of a selected panel of 12 potential genetic biomarkers were analyzed in blood using RT-qPCR...

BACKGROUND: There is an increasing recognition of epidemics of primarily tubular-interstitial chronic kidney disease (CKD) clustering in agricultural communities in low- and middle-income countries (LMICs). Although it is currently unclear whether there is a unified underlying aetiology, these conditions have been collectively termed CKD of undetermined cause (CKDu). CKDu is estimated to have led to the premature deaths of tens to hundreds of thousands of young men and women over the last 2 decades...
