Abstract
Introduction- Acute kidney injury (AKI) is now an established and preventable cause for chronic Kidney disease. Poor outcome of Acute Kidney Injury is influenced by severity and duration of AKI... Aims-We hypothesize that recurrent episodes of acute kidney injury are associated with adverse renal and patient related outcome. Material and Methods- Study was undertaken to look into etiological risk factors for recurrent AKI and its effect on renal and patient related outcome. This retrospective analytical study was conducted at tertiary care health care centre from northern part of India from January 2003 to December 2013. All patients with the diagnosis of "acute renal failure" or "acute kidney injury" as their hospital admission diagnosis was identified and individuals with recurrent Acute Injury were included in the study. Results- Recurrent acute kidney injury was found in 21 (0.56%) of 3698 patients who presented with acute kidney injury during the 10 years period. Topical infections were the most common etiology of recurrent AKI followed by rhabdomyolysis and intravascular hemolysis leading to pigment nephropathy. Acute tubular necrosis was the most common histopathological diagnosis among patients biopsied. As the episodes of AKI increased from 2 to >2 episodes, there was poor immediate as well as late renal outcome. 50% were protienuric and 87.5% were hypertensive at 1 year among patients who had >2 episodes of AKI while it was 15.3% and 7.69% among patients having < 2 episodes respectively. Conclusion- Recurrent episodes of AKI are associated with poor patient and renal outcome suggesting that each episode of acute kidney injury needs close evaluation and follow up following hospital discharge with particular attention to renal outcomes.
