Clostridium Difficile and Noncirrhotic Hyperammonnemia in a Patient With COVID-19 Infection

Abstract

Clostridium difficile is a bacterial infection that usually presents with diarrhea and is mostly associated with previous antibiotics use. Patients with coronavirus disease 2019 (COVID-19) generally have respiratory symptoms but can also present with diarrhea. Noncirrhotic hyperammonemia is an infrequent presentation and is treated with lactulose. We report the case of a 40-year-old male who was admitted to our hospital with abdominal pain, diarrhea, shortness of breath, and confusion. During hospitalization, the patient tested positive for COVID-19 and C. difficile, and oral vancomycin was administered. His kidney functions improved, but he remained confused. His ammonia levels were elevated, and he was not treated with lactulose due to ongoing diarrhea secondary to C. difficile infection.
