Clinical and laboratory characteristics of influenza in pregnant women in the epidemiological season of 2013-2014

Abstract

By force of hormonal and physiological changes occurring in the body throughout pregnancy, in the case of the flu, pregnant women are at greater risk of developing complications. In this regard, the study of clinical and pathogenetic features of influenza in pregnant women deserves special attention. So, on the basis of epidemiological data over the past few decades, WHO experts have included pregnant women in groups at risk of severe (complicated) course of the flu. The flu for a pregnant female is a dangerous infection, representing a real threat to the health of the expectant mother and her child. The clinical picture of influenza in pregnant women can vary significantly, and severe complications combine with the development of a pathology of pregnancy, which ultimately exacerbates the condition as well an expectant mother as the fetus. For the study both of the character of the clinical course of influenza in pregnant women and the mechanism of the immunosuppressive state FGBU "Influenza Research Institute" performed a simple multi-center comparative study on the base of the infectious-disease units of the GBOU "NGMU" and the Medical University "KrasGMU named after. prof. V.F. Voyno-Yasenetsky" of the Ministry of Health of the Russian Federation. The obtained results allowed to reveal some clinical and immunological features of the course of influenza in pregnant women: at the peak of the disease there was noted a significant inhibition of induced production of IFN-γ.
