Human rhinoviruses (HRV) usually cause upper airway infections. However, viral replication in the tracheobronchial tree has been disclosed, although its clinical role is poorly known. We evaluated the prevalence of HRV in 159 bronchoalveolar lavages from 88 patients and describe a lung transplant recipient with a high HRV load in association with acute rejection. HRV was detected in 22/88 patients (25.0%): 7/18 lung transplant recipients, 11/41 immunocompetent, and 4/29 immunocompromised (p = n.s.). No lung disease was significantly associated with HRV positivity. It should be recommended to include HRV in the virological diagnostic work-up of lower respiratory specimens to elucidate their role.

Abstract
Human rhinoviruses (HRV) usually cause upper airway infections. However, viral replication in the tracheobronchial tree has been disclosed, although its clinical role is poorly known. We evaluated the prevalence of HRV in 159 bronchoalveolar lavages from 88 patients and describe a lung transplant recipient with a high HRV load in association with acute rejection. HRV was detected in 22/88 patients (25.0%): 7/18 lung transplant recipients, 11/41 immunocompetent, and 4/29 immunocompromised (p = n.s.). No lung disease was significantly associated with HRV positivity. It should be recommended to include HRV in the virological diagnostic work-up of lower respiratory specimens to elucidate their role.
