Snakebite-associated acute kidney injury (AKI) poses a significant health burden in the South Asia region, resulting in considerable morbidity and mortality. Multiple factors contribute to the pathogenesis of AKI following snakebites, including hypotension, intravascular haemolysis, disseminated intravascular coagulation, rhabdomyolysis, thrombotic microangiopathy (TMA) and direct nephrotoxicity. Clinical features manifest as anuria, oliguria, haematuria, abdominal pain and hypertension. Diagnosis is supported by elevated serum creatinine levels and urine output monitoring. Renal histology studies revealed a spectrum of lesions, including acute tubular necrosis, renal cortical necrosis, glomerulonephritis and TMA. Management strategies centre around timely administration of antivenom, fluid and electrolyte balance and dialysis to improve renal outcomes. While dialysis has demonstrated efficacy in reducing AKI-related mortality rates, the use of fresh frozen plasma and therapeutic plasma exchange may be the subject of some controversy. Understanding the pathophysiological link between coagulopathy, TMA and AKI is important for tailoring effective treatment approaches. Species-specific randomized controlled trials are imperative to evaluate targeted interventions. In tackling the complexities of snakebite-associated AKI and chronic kidney disease, a multidisciplinary approach integrating clinical management with rigorous research efforts is essential. This collaborative endeavour aims to confront the challenges posed by these conditions and improve patient outcomes in the affected regions.
