[Complicated form of A/HINI (2009) influenza in pregnant women].
We undertook prospective and retrospective analysis of 120 cases of A/HINI (2009) influenza complicated by pneumonia in pregnant women with the purpose of comprehensive assessment of these conditions taking into account relevant risk factors and preventive measures. Control groups were comprised of 100 pregnant women with uncomplicated influenza and 100 ones who did not fall ill during flu pandemic. The risk of severe disease and probability of its fatal outcome in pregnant women were 2.5 and 2.4 times those in the general population. Most women developed pneumonia in the 3d trimester Risk factors offlu complications included smoking, obesity, underlying respiratory and cardiovascular diseases, sexually transmitted infections. Combined prophylaxis reduced probability of pandemic influenza in pregnant women by 5.6-7 times. Severe forms of the disease were due to manifest symptoms of intoxication and concomitant pneumonia. The clinical picture of lethal cases was characterized by severe pneumonia with subtotal lung involvement, rapid progress of acute respiratory distress syndrome, and development of polyorgan insufficiency.
