Abstract
Adenoviruses usually cause asymptomatic or mild infection, but occasionally they produce various severe syndromes including neurological disorders. Association of adenovirus infection with acute flaccid paralysis has been investigated. Shedding of adenovirus with feces was detected in 1.05% of young children (mostly infants) with acute flaccid paralysis syndrome versus 0.42% in healthy contact children (P < 0.01). However, 85% of adenoviruses in the pediatric AFP patients belonged to HAdV‐C species, which does not have a known neuropathogenic potential. Also, 40% of adenoviruses were isolated from patients with consequently established diagnosis of traumatic neuritis at the discharge, which was not compatible with virus ethology of neurological lesions. Higher adenovirus prevalence in young neurological patients could be affected by an underlying immune deficiency or by congestion in children's hospitals. Indeed, among 70 patients (40 infants, 30 adults) with primary immune deficiencies, asymptomatic shedding of adenoviruses was found in 10–17%; in one adult patient a mixture of HAdV‐C2 and HAdV‐D15 persisted for several months. Adenoviruses also could be detected in feces of 12% and 57% of healthy young children from two orphanages, respectively. A significant fraction of samples in these groups contained adenovirus mixtures. Therefore, immune deficiencies and congested groups in children's facilities (orphanages and hospitals) could affect significantly the prevalence of adenovirus shedding. The role of adenoviruses in AFP requires further study. J. Med. Virol. 84:75–80, 2011.This publication has 30 references indexed in Scilit:
