Increasing number of epidemiological and clinical studies to date showed that the pandemic influenza A (H1N1) 2009, by its characteristics, significantly differs from infection caused by seasonal influenza. Therefore, the information about clinical spectrum of manifestations, risk factors for severe form of the disease, treatment and outcome in patients with novel flu are still collected. METHODS; A total of 98 patients (mean age 32 +/- 15 years, range 14-88 years) with the signs and symptoms of novel influenza were treated in the Clinic for Infectious and Tropical Diseases, Military Medical Academy. There were 74 (75.5%) patients with suspected influenza A (H1N1) 2009, 10 (10.2%) with the likelihood and 14 (14.3%) with the confirmed influenza. In all the patients we registered the basic demographic data, risk factors for severe disease, symptoms and signs of influenza, laboratory tests and chest radiography. We analyzed antiviral therapy use and disease outcome (survived, died). ⋯ Novel influenza A (H1N1) is most commonly manifested as a mild acute respiratory disease, which usually affects young healthy adults. A small number of the patients develop severe illness with acute respiratory failure and death. Patients seem to have benefit from antiviral therapy especially in first 48 hours.

Pandemic of A H1N1 influenza is noted for its rapid spreading and life-threatening consequences like acute respiratory distress syndrome (ARDS) which requires mechanical ventilation (MV) and intensive therapy (IT).The aim of the study was to determine the significance of mechanical ventilation application in the presence of comorbidities on the outcome of the disease and patients with severe forms of acute influenza caused by A H1N1 virus. ⋯ Intensive therapy of patients with ARDS due to A H1N1 influenza virus requires MV which should be carried out according to guidelines of international expert forums. That is in accordance with our unexpected observation on negative correlation between duration of MV and fatal outcome. Intensive treatment of these patients, specially MV, can be very prolonged and, therefore, requires specialized teams of anesthesiologists, separate, isolated intensive therapy units and high level of medical staff protection, as was the case in this study, so no member of medical staff was infected.
