A rare case of severe leptospirosis infection presenting as septic shock in a non-endemic area: a case report and literature review

An Unusual Presentation of Leptospirosis: A Case of Septic Shock and Proteinuria

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.

Leptospirosis: a clinical and diagnostic challenge

We present the case of a man in his early 50s who presented with a history of fever, malaise and jaundice. Initial investigations showed liver and renal dysfunction with no discernible cause for the septic process. On starting intravenous antibiotics, the patient developed a septic-shock-like reaction requiring transfer to intensive care. A diagnosis of leptospirosis was eventually established through an extensive and thorough history leading to a stepwise approach to investigations. Treatment targeting leptospirosis was delivered with noticeable clinical improvement.

Leptospirosis-Induced Septic Shock and Multi-Organ Dysfunction Syndrome: A Complex Case of Zoonotic Infection in a Young Female Patient

Leptospirosis, a zoonotic infection caused by the Leptospira bacteria, can manifest with varying clinical severities, ranging from subclinical disease to severe multiorgan failure. This progression to severe multiorgan failure, also known as multi-organ dysfunction syndrome (MODS), is a life-threatening condition characterized by the dysfunction of two or more organ systems. Often, MODS is a consequence of events triggered by underlying pathologies, such as severe infections, including those caused by Leptospira. Here, we present a case report of a 29-year-old female patient who initially sought care for increased temperature, fatigue, diarrhea, and vomiting. The patient exhibited signs of septic shock (SS). Her medical history raised suspicion of multiple potential sources of infection. She experienced cat scratch several days before admission, accompanied by an enlarged inguinal lymph node and a history of frequent interaction with animals, as well as freshwater exposure, which prompted investigations into various zoonotic infections. Empiric treatment was started, and, subsequently, after several days, Leptospira titer came back positive. Over the hospitalization course, the patient developed multi-organ failure, which was attributed to the underlying Leptospira infection. The complexity and severity of the patient's condition underscore the far-reaching impact of leptospirosis in precipitating a spectrum of systemic complications culminating in multiorgan failure. The treatment interventions yielded successful outcome, and the patient recovered in one month. This case report highlights the difficulties in diagnosing and treating patients with multiple possible sources of infection. it emphasizes the need for a careful history-taking and high level of suspicion for zoonotic infections in patients with a history of animal exposure and clinical symptoms suggestive of infectious diseases.
