Chronic kidney disease of uncertain etiology (CKDu) has been a severe burden and a public health crisis in Sri Lanka over the past two decades. Many studies have established hypotheses to identify potential risk factors although causative agents, risk factors and etiology of this disease are still uncertain. Several studies have postulated that fungal and bacterial nephrotoxins are a possible etiological factor; however, the precise link between hypothesized risk factors and the pathogenesis of chronic kidney disease has yet to be proven in prior studies.Leptospirosis and Hantavirus infections are important zoonotic diseases that are naturally maintained and transmitted via infected rodent populations and which present similar clinical and epidemiological features. Both infections are known to be a cause of acute kidney damage that can proceed into chronic renal failure. Several studies have reported presence of both infections in Sri Lanka. Therefore, we hypothesized that pathogenic Leptospira or Hantavirus are possible causative agents of acute kidney damage which eventually progresses to chronic kidney disease in Sri Lanka.The proposed hypothesis will be evaluated by means of an observational study design. Past infection will be assessed by a cross-sectional study to detect the presence of IgG antibodies with further confirmatory testing among chronic kidney disease patients and individuals from the community in selected endemic areas compared to low prevalence areas. Identification of possible risk factors for these infections will be followed by a case-control study and causality will be further determined with a cohort study.If the current hypothesis is true, affected communities will be subjected for medical interventions related to the disease for patient management while considering supportive therapies. Furthermore and possibly enhance their preventive and control measures to improve vector control to decrease the risk of infection.
