Abstract

Abstract: Entamoeba histolytica infections, which can be asymptomatic, are endemic to developing countries; traveling to such countries is a risk factor for contracting these infections. A 65-year-old Japanese man was hospitalized for coronavirus disease 2019 (COVID-19)-associated respiratory distress, and was treated with remdesivir, dexamethasone, and oxygen supplementation. Although his respiratory condition improved and the oxygen support was discontinued, he developed a fever, severe abdominal pain, and diarrhea on day 13 of hospitalization. Fifteen years ago, he was hospitalized for diarrhea of an unknown origin in Suzhou, China, and had a history of passing loose stools for 1 year. Contrast-enhanced abdominal and pelvic computed tomography revealed liver abscesses in both lobes and intestinal edema from the ascending colon to the descending colon. The abscesses were suspected to be amebic based on the characteristics of the drained abscess fluid. The patient was treated with cefotaxime and metronidazole, and his temperature declined and abdominal pain improved. A culture analysis of abscess fluid yielded negative findings; however, polymerase chain reaction analyses of abscess and stool samples were positive for Entamoeba histolytica. We speculated that the patient was infected with Entamoeba histolytica while in China, and that the corticosteroid usage for COVID-19 had exacerbated the infection. Clinicians should be aware that corticosteroid treatments can lead to recurrent invasive amebiasis in asymptomatic amebic carriers. Highlights: Unfamiliar adverse effects of corticosteroids are exacerbations of parasitic infections, such as amebic infections. Corticosteroids are increasingly used to treat patients with severe COVID-19 disease. Increased use of corticosteroids will lead to more acute exacerbations of amebic infections. Clinicians need to suspect amebic infections when corticosteroid-treated patients with COVID-19 have abdominal symptoms.
