Linking AKIN stages with tropical infection induced acute kidney injury among Indian patients.

Tropical acute febrile illness often causes AKI in India and outcome linkage with AKIN staging is still limited. Hence, we studied 150 adults with tropical infection related AKI staged by AKIN at 48 hours and followed till discharge or death. Leptospirosis was the main cause and higher AKIN stage showed more oliguria organ dysfunction longer stay higher dialysis need with mortality rising to 40.9% in stage III. This study adds a clear stage based risk gradient plus simple bedside red flags and basic labs for early triage and it supports timely aggressive support and dialysis referral to reduce avoidable deaths.
