Previous studies reported controversial results regarding the possible association of recurrent genital herpes during pregnancy with a higher risk of preterm birth/low birth weight in newborns. Thus, birth outcomes of mothers with prospective and medically recorded symptomatic recurrent genital herpes confirmed by serological examination and of mothers without genital herpes were compared in the population-based large data set of the Hungarian Case-Control Surveillance of Congenital Abnormalities. Our results showed that of 38,151 newborn infants, 86 (0.23%) had mothers with symptomatic recurrent genital herpes confirmed by serological examination during pregnancy. The rate of preterm births (14.0% vs. 9.2%) was higher in babies born to mothers with symptomatic recurrent genital herpes (OR with 95% CI: 1.7, 1.0–3.1) and this increase showed a trimester dependence with the highest rate in the third trimester (23.5%; OR with 95% CI: 2.6, 1.5–4.5). In conclusion, clinically diagnosed recurrent genital herpes during the third trimester of pregnancy associated with high risk for preterm birth.

Hungarian Preconceptional Care includes the preconceptional screening of sexually transmitted infections/disorders (STD) and vaginal candidosis of potential mothers and pyospermia of potential fathers. The aim of this study was to evaluate the effect of this screening and treatment for the rate of preterm births. Clinical and subclinical vaginal candidiasis (asymptomatic candida colonisation), combination of STD and vaginal candidiasis, STD without vaginal candidiasis, finally women without STD and vaginal candidiasis as references were evaluated in 4,672 pregnant women. The association of STD in pregnant women with higher risk of preterm birth was confirmed. However, an association was also found between clinically diagnosed vaginal candidiasis, asymptomatic candida colonisation, and a higher risk for preterm births. This risk was reduced with clotrimazole treatment. However, pregnant women without recognized STD and/or vaginal candidiasis had a higher risk for preterm birth than pregnant women with STD or vaginal candidiasis after appropriate treatment. Thus the conclusion of the study is that the preconceptional screening of STD and vaginal candidiasis followed by appropriate treatment is important to prevent a certain part of preterm birth but it is necessary to improve the efficacy of the previously used methods for this screening.

Human chorionic gonadotropin (HCG) is used parenterally for treatment of threatened abortions and repeated spontaneous abortion in pregnant women. No controlled epidemiological studies of preterm birth and low birthweight newborns in pregnant women with HCG treatment have been published while the results of animal investigations were controversial. The data of 97 pregnant women with HCG treatment in the second and third months of pregnancy due to threatened abortion and/or previous spontaneous abortion(s) was compared with the data of other 38,054 pregnant women in the population-based large data set of the Hungarian Case-Control Surveillance of Congenital Abnormalities. There was no difference in mean gestational age at delivery and birth weight, in addition the rate of preterm birth and low birthweight newborns. Parenteral HCG treatment in the early pregnancy due to threatened abortion did not associate with a higher risk for preterm births or low birthweight newborns. However, a higher occurrence of gestational diabetes was found in pregnant women with HCG treatment and there was a slight male excess among newborn infants (p=0.06).
