Eight Year Prospective Study of Adenoviruses Infections in Hospitalized Children. Comparison with Other Respiratory Viruses.

Calvo C, García-García ML, Sanchez-Dehesa R, Román C, Tabares A, Pozo F, Casas I - PLoS ONE (2015)

Bottom Line: We genotyped 154 HAdVs.A total of 262 children had fever (64.9%); 194 suffered hypoxia (48%), and 147 presented infiltrate in chest x-rays (36.4%).The most frequent diagnoses were recurrent wheezing or asthma (51.7%), bronchiolitis (18.3 %), and pneumonia (11.9%), and 46 (11.4%) episodes required prolonged hospitalization (>7 days) due to the severity.

ABSTRACT
Human adenovirus (HAdV) cause upper and lower respiratory tract infections. However, there are few large prospective studies focused on HAdVs acute infections requiring hospitalization. From 2005 to 2013 a prospective study was conducted on children admitted with acute respiratory infections. Specimens of nasopharyngeal aspirate were taken for virological study by PCR and clinical data was recorded. HAdV specimens were genotyped. Frequency and clinical course of HAdV infections were compared with RSV, rhinovirus (RV), human bocavirus (HBoV) and influenza in the same population. HAdV was detected in 403 cases of 2371 confirmed viral infections (17.2%) , of which 154 were single virus infections (38%). We genotyped 154 HAdVs. The most frequent genotypes were HAdV-3 (24%), HAdV-6 (21%), and HAdV-5 (20%). A total of 262 children had fever (64.9%); 194 suffered hypoxia (48%), and 147 presented infiltrate in chest x-rays (36.4%). The most frequent diagnoses were recurrent wheezing or asthma (51.7%), bronchiolitis (18.3 %), and pneumonia (11.9%), and 46 (11.4%) episodes required prolonged hospitalization (>7 days) due to the severity. Adenovirus single infections were compared with single infections of 598 RSV, 494 RV, 83 influenza and 78 HBoV. Significant clinical differences were found between HAdV, RSV and RV infections.

Mentions: Regarding the seasonal distribution of the virus, we found significantdifferences between HAdV monthly circulations and each of the other virusesstudied (Fig 3). HAdVpredominated in spring with another peak in December, while RSV circulatesin November, December and January (p = 0.001), similar to HBoV circulation(p = 0.001). Higher influenza incidence takes place in January and February(p = 0.001). RV infections occur throughout the year, with a higherincidence in September and October (p = 0.001)
