Background: Human parvovirus B19 infection during
pregnancy may cause fetal loss. The aim of this study was to detect the
incidence of B19 infection in cases of nonimmune hydrops fetalis (NIHF),
spontaneous abortion, intrauterine fetal death (IUFD) and in healthy pregnant
women. Material and Methods: Serum
samples of pregnant women with NIHF (9), spontaneous abortion (27), IUFD (5)
and healthy pregnant women (47) were tested by nested PCR to detect B19 DNA and by ELISA test for B19 specific IgM and IgG
antibodies. In other case series of the study, paraffin-embedded fetal and
placental tissue samples from 33 NIHF cases and 19 spontaneous abortion cases
and placental tissues from 40 normal pregnant women at term were analyzed for B19 DNA by nested PCR. Results: B19 infection was diagnosed by PCR and ELISA tests using
serum samples in 4 (44%) of 9 NIHF cases and 9 (33%) of 27 spontaneous abortion
cases and in 1 (20%) of 5 IUFD cases. In addition, B19 IgG prevalence was found
to be 51% (24/47) in the control group. In other case series, the presence of B19 DNA in
fetal and placental tissue samples was found in 14 (42.4%) of 33 NIHF cases and
6 (31.5%) of 19 spontaneous abortion cases, while in none of 40 placental
tissues samples from the control group. Conclusion:
Our findings show that the incidence of parvovirus B19 infection in NIHF and
spontaneous abortion cases is relatively high. Nested PCR and ELISA tests
should be used together for the early diagnosis of B19 infection in pregnant
women.
