RESUMO
Comparative analysis of the clinical laboratory data from 419 children and 468 adults hospitalized during the pandemic of A (H1N1pdm 2009) and pre- and post-pandemic periods (2010-2013) showed that the clinical presentation of the pandemic influenza in patients of all ages is generally typical for influenza, and its character is determined by the degree of involvement of lungs in the process. Besides, the incidence of pneumonia in adults is statistically significantly higher than in children. During all compared periods hyperthermia (≥ 39 degrees C), hemorrhagic and dyspeptic syndrome were observed. Some differences in the main clinical manifestations of pneumonia in recovered patients and patients who died of the severe pandemic influenza were observed. The regularities of the cytokine reactions depending on the intensity of intoxication and occurrence of complications were determined in patients of all ages. Medical efficacy of inclusion of antiviral chemotherapeutic agents into complex influenza treatment was proved.
