- Abstract
Background: Chronic rhinosinusitis (CRS) can be aggravated by viral upper respiratory infections. We aimed to investigate whether any specific human rhinovirus (HRV) serotype is more common in the mucosa of CRS patients, and to find any defining clinical characteristics, according to the various HRV serotypes., Methods: A prospective case-control study was conducted to determine HRV serotypes in 111 CRS patients and 51 non-CRS controls. No participant had a history of upper respiratory infection over a 4-week period. Nasal lavage fluids and turbinate epithelial cells were collected prospectively. When HRV was detected with multiplex polymerase chain reaction (PCR), strains were further characterized by sequencing the VP4/VP2 region of the HRV genome., Results: HRV was detected in 40 CRS subjects (36%) and 11 non-CRS controls (21%). The overall detection rates of HRV in CRS patients were higher than in non-CRS controls (p < 0.05). Of the 8 serotypes detected in CRS patients, 5 belonged to HRV-A and 3 belonged to HRV-B; HRV-C was not detected. In non-CRS controls, only HRV-A was identified, with only 2 serotypes detected (HRV-A13 and HRV-A16). HRV-B and C were not detected., Conclusion: The high prevalence of HRV in CRS patients was confirmed in our study. However, we were unable to determine whether certain HRV serotypes are more predominant in CRS patients than non-CRS controls. HRV-A13 was the most common serotype in both CRS patients and non-CRS controls. We could not find any differences in the clinical characteristics according to the HRV serotypes in CRS patients., (© 2014 ARS-AAOA, LLC.)
