Parvovirus B19 in pregnancy and its effects on the baby

Parvovirus B19 Infection in Pregnancy: Clinical Manifestations and Fetus/Newborn Outcome

Observational Fondazione IRCCS Policlinico San Matteo di Pavia · NCT07338279

This project follows pregnant women who get parvovirus B19 and their babies to see how often the infection causes problems for the fetus or newborn.

What this trial studies

Researchers will collect clinical data from pregnant women over 18 with confirmed parvovirus B19 infection and from their neonates to determine the rate of intrauterine transmission and fetal/newborn complications. The study will record maternal risk factors, pregnancy outcomes, management interventions, and longer-term sequelae in infants. Data will be gathered at participating hospitals in Lombardy, Italy, and analyzed to identify factors associated with worse outcomes and to evaluate the effectiveness of current management approaches. As an observational registry, no experimental treatments are assigned.

Who should consider this trial

Good fit: Ideal candidates are pregnant women older than 18 years with confirmed parvovirus B19 infection and their newborns.

Not a fit: People without parvovirus B19 infection, those under 18, or those unable to attend follow-up at the participating hospitals are unlikely to benefit from this project.

Why it matters

Potential benefit: If successful, the findings could help clinicians better predict fetal risk, refine management strategies in pregnancy, and provide clearer counseling for affected families.

How similar studies have performed: Previous observational work has documented risks such as fetal hydrops and pregnancy loss after maternal parvovirus B19 infection, so this study builds on existing clinical knowledge rather than testing a novel therapy.
