A Case of Hypoxemic Primary Cytomegalovirus Disease Shortly After Recovery From Coronavirus Disease in a Young Immunocompetent Man
Abstract
Cytomegalovirus (CMV) reactivation has been identified as a significant predictor of death in patients hospitalized with coronavirus disease (COVID‐19). However, reports of concurrent or subsequent primary CMV disease in young immunocompetent patients with COVID‐19 are rare. We present a rare case of primary CMV disease manifesting as pneumonia and acute respiratory failure in a young immunocompetent man, which developed shortly after recovery from moderate COVID‐19. A 19‐year‐old immunocompetent man was admitted to our hospital with a diagnosis of COVID‐19 pneumonia on the 10th day of COVID‐19 onset. His symptoms improved following administration of intravenous dexamethasone, oral prednisolone, and oral azithromycin hydrate and levofloxacin hydrate. He was discharged on the 16th day of COVID‐19 onset. However, he developed a cough and fever 5 days after discharge, and he was readmitted to our hospital 8 days after discharge. Serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), C‐reactive protein (CRP), and lactate dehydrogenase (LDH) were elevated compared to those during the first admission. Computed tomography revealed new ground‐glass attenuations and the improvement in the aforementioned COVID‐19 pneumonia. Next day, his percutaneous arterial oxygen saturation levels dropped to 89% breathing room air. Serum antibodies against CMV: immunoglobulin M (CMV IgM) and immunoglobulin G (CMV IgG), which were negative on the day of the first…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
