Abstract
Leptospirosis is a global health concern, particularly in tropical regions, with clinical symptoms varying from mild fever to severe organ dysfunction. We present a case of a 57-year-old male with septic shock and acute kidney injury due to acute leptospirosis. The patient's rapid progression to shock within a day of generalized symptoms was unusual. The patient's infection ultimately resolved with ceftriaxone and he was discharged after 14 days of therapy. The pathogenesis of severe leptospirosis is believed to be due to vasculitis, with organ damage caused by the leptospira bacteria and immune-mediated mechanisms. Diagnostic investigations include blood cultures and polymerase chain reactions, which are beneficial for early diagnosis. The management of patients depends on the severity of symptoms and other health conditions, as well as antibiotics and hydration. However, leptospirosis can lead to a wide range of complications, including neurological, ocular, hematological, and gastrointestinal involvement, necessitating vigilant monitoring and management.
