[Maternofetal infection with human parvovirus B19. Apropos of 2 cases]. / Infection materno-foetale à parvovirus humain B19. A propos de deux observations.

ABSTRACT

Two cases of maternal-fetal human parvovirus B19 infection are reported. The first case involved a feto-placental anasarca occurring during the third trimester and complicated by in-utero death with expulsion of a fetus with multiple malformations. The second case involved meconial peritonitis during the second trimester with favourable outcome after cesarean section and resolution of the digestive syndrome. Proof of PV B19 infection was obtained by identifying M specific immunoglobulins and viral DNA. After a review of the clinical situations most often encountered and the particular features of these two cases, therapeutic attitudes are proposed for this infection of major gravity during pregnancy.
