Background. Acute kidney injury (AKI) is a common complication of snake envenomation. However, the long-term renal outcomes of such patients are not well defined. We aimed to determine the proportion of patients who developed AKI, characterize the presenting syndromes and ascertain the long-term resolution of AKI. Methods. We did a cohort study with prospective follow- up from two centres in southern India. All admitted patients >15 years of age with snake envenomation and serum creatinine ≥1.5 mg/dl over the past 10 years were identified through their discharge summaries. These patients were prospectively contacted, interviewed telephonically and requested to come for a hospital review. Results. Of the 866 patients screened, 1 84 developed AKI (21.2%). Among these, 53% had combined renal, haematological and neurological manifestations; 33.6% required admission to the intensive care unit and 38% were dialysed. On follow-up of hospital records the creatinine of 49% of patients had normalized. Of those admitted, 36% were contacted and none had a known renal disease or were on dialysis. Among these, 16 patients came to the hospital for review and only 2 had an elevated creatinine. The total mortality was 1 4. Conclusion. AKI is an important cause of morbidity with snake envenomation and a proportion will require dialysis. The mortality in our study was low and long-term renal outcomes were relatively good.
