DENGUE DURING PREGNANCY: ASSOCIATION WITH LOW BIRTH WEIGHT AND PREMATURITY
The aim of this study was to evaluate the effects of dengue virus infection during pregnancy and its correlation with low birth weight, prematurity, and asphyxia. A non-concurrent cohort study reveals the association of dengue during pregnancy with prematurity and low birth weight, when birth occurred during the maternal-fetal viremia period (p = 0.016 and p < 0.0001, respectively)

Rio de Janeiro, RJ, Brasil.Perinatal transmission of dengue virus was confirmed by the evidence of virus in fetal tissue, newborn serum, and
placenta of pregnant women. Abortion, several different clinical findings, and placental inflammatory findings were
documented. No association was seen between severity of maternal dengue and disease of the newborn
Dengue infection in pregnancy and its impact on the placenta
A histopathological and immunohistochemical study was conducted in placental tissues and retained products of conception from 24 patients with confirmed dengue infection during pregnancy. The immunohistochemical assay was positive for dengue virus in 19 placental and three ovular remnants analyzed. The light microscopic findings were signs of hypoxia, choriodeciduitis, deciduitis and intervillositis and the viral antigens were found in cytoplasmic of the trophoblast, villous stroma and decidua. Our results suggest that immunohistochemistry could be used as a laboratory confirmation method for dengue in pregnant women, especially in endemic areas when embedded material is the only material available
