Acute Respiratory Distress Syndrome Secondary to Enterovirus-Human-Rhinovirus Infection in an Adult

Enterovirus-human-rhinovirus (EV-HRV) are small RNA viruses that are airborne and can spread by direct contact or fomites and usually cause the common cold, asthma and chronic obstructive pulmonary disease exacerbation. EV-HRV-associated acute respiratory distress syndrome (ARDS) is common in children but is a rare cause of ARDS in adults. ARDS is defined according to the Berlin criteria and can be mild, moderate or severe depending on the PaO to FiO ratio. We report a case of a 70-year-old female with cardiac comorbidities, emphysema, second-hand smoking of 25 years, on methotrexate for rheumatoid arthritis presenting with ARDS secondary to EV-HRV infection. Despite initial treatment with appropriate antibiotics, steroids, low tidal volume mechanical ventilation, rescue maneuvers such as ventilation in prone positioning, paralyses, and inhaled nitric oxide, she passed away. EV-HRV causes upper respiratory tract infections but causes cytokine releases such as IL-1, IL-6, and IL-8 in the lower respiratory tract and in the blood which can cause ARDS. Very few cases of EV-HRV ARDS in immunocompetent adults are reported in the literature. Female sex is also associated with EV-HRV ARDS. No antiviral therapy exists for patients critically ill with EV-HRV; however, one case of successful treatment with high-dose intravenous vitamin C (HIVC) is reported in the literature. EV-HRV is one of the most common viruses identified in patients admitted with viral pneumonia in the intensive care unit. It should not be forgotten as a cause of ARDS.
