Severe Adult Rotavirus Gastroenteritis: A Rare Case with Multi-Organ Failure and Critical Management

Abstract

BACKGROUND Infectious diarrheal illnesses such as rotavirus gastroenteritis are significant contributors to childhood morbidity and mortality, especially in low socio-demographic index regions. Major advances in addressing this issue include sanitation and clean water initiatives, as well as rotavirus immunization. In Australia, a robust vaccination program has significantly reduced childhood rotavirus infections, leading to decreased hospitalizations and mortality. However, cases of adult rotavirus still occur, and although these adult patients usually do not require interventional management, it is possible for them to present critically unwell and require resuscitation. CASE REPORT A previously well 65-year-old man presented to the Emergency Department febrile and hypotensive with severe diarrhea attributed to rotavirus. Clinically, he presented with mixed hypovolemic and septic shock. Despite initial resuscitation, he had multiple severe acute end-organ complications, secondary to poor perfusion. He acquired an acute kidney injury, type-2 myocardial infarction, and ischemic hepatic injury. The mainstay of management was rapid fluid resuscitation, continuous renal replacement therapy, and monitoring in the Intensive Care Unit; however, it was crucial to empirically treat for other causes of shock. CONCLUSIONS To the best of our knowledge, there is a scarcity of reports documenting the management of severe rotavirus gastroenteritis in adults. We recommend advising elderly patients to avoid contact with individuals with diarrheal illnesses, especially rotavirus gastroenteritis. Clinicians should also promote awareness regarding the potential severity of a disease that is typically managed conservatively, and be aware that intervention can be required in severe gastroenteritis.
