Objective. To estimate the incidence of respiratory viruses in rhinosinusitis and acute suppurative otitis media (ASOM) in children

Materials and methods. The investigators obtained 99 aspirates from the paranasal sinuses and 58 samples of tympanic cavity discharge in patients diagnosed with acute rhinosinusitis and ASOM. Their microbiological examination involved bacteriological and virological assays. Real-time polymerase chain reaction with fluorescence hybridization probes using a Rotor-Gene 6000 thermal cycler («Corbett Research», Australia) was used to identify viruses (PC virus, metapneumovirus, parainfluenza viruses types 1, 2, 3, and 4, rhinovirus, Groups B, C, and E adenoviruses, coronavirus, bocavirus, as well as also enterovirus for ASOM patients. «InterLabService» (Moscow) reagents were applied. Results. The most common cause of rhinosinusitis was bacteria (32.3%) and that of ASOM was viruses (34%). The leading bacterial agent of the disease in patients with both rhinosinusitis and ASOM was Streptococcus pneumonia; its detection rate was higher in the patients with ASOM (45.32% for rhinosinusitis and 47.7% for ASOM). The most common virus was rhinovirus in the patients with rhinosinusitis (44.2% of cases) and RS virus in those with ASOM (47.7%).
