Enterovirus-Human Rhinovirus as a Leading Cause of ARDS in a Liver Transplant Recipient

A 35- year- old man with a prior history of liver transplantation 18 months ago was admitted to our Intensive Care Unit (ICU) with fever and worsening dyspnea and was diagnosed with severe pneumonia leading to Acute Respiratory Distress Syndrome (ARDS). He had a prolonged hospitalization and was treated with empiric broad spectrum intravenous antibiotics, oseltamivir, trimethoprim/sulfamethoxazole, and subsequently caspofungin and ganciclovir. Blood, nasopharyngeal, as well as Bronchoalveolar Lavage (BAL) culture and Polymerase Chain Reaction (PCR) were negative for all viral, bacterial, and fungal causes of pulmonary infection except Enterovirus-Human Rhinovirus (EV-HRV) that was positive with high titers on BAL and swab specimens. Consequently, the diagnosis of EV-HRV pneumonia complicated by ARDS was established. The patient gradually improved and was discharged from the hospital after 3 weeks. This report highlights EV-HRV as a cause of ARDS in immunocompromised adults.
