Managing infections in pregnancy.

Area of Science:

• Obstetrics and Gynecology
• Infectious Diseases
• Neonatal Medicine

Background:

• Over 400 publications address pregnancy infections, focusing on viral and parasitic causes like cytomegalovirus (CMV) and toxoplasmosis.
• Recent severe influenza outbreaks highlight emerging threats in prenatal care.
• Progress in epidemiological knowledge, neonatal treatment, and prenatal diagnosis drives current management strategies.

Purpose of the Study:

• To review recent advancements in diagnosing and managing congenital infections during pregnancy.
• To assess the current status and future directions for cytomegalovirus (CMV) and toxoplasmosis management.
• To address the implications of influenza infections in early pregnancy.

Main Methods:

• Review of over 400 publications from the last two years.
• Analysis of epidemiological data on congenital infections.
• Evaluation of diagnostic and therapeutic interventions for fetal infections.

Main Results:

• Cytomegalovirus (CMV) infection prevalence remains stable, with improved fetal infection prediction and promising therapeutic developments, including a potential vaccine.
• Toxoplasmosis prevalence is decreasing in Europe, raising questions about screening effectiveness and prenatal treatment efficacy.
• Influenza infection in early pregnancy is linked to an increased risk of congenital malformations, likely due to maternal hyperthermia.

Conclusions:

• Accurate dating of maternal primary infection is essential for effective prenatal management, including surveillance and therapy.
• Heightened prenatal surveillance is recommended after influenza infection in early pregnancy due to potential risks of congenital malformations.
• Further research, including randomized controlled trials, is needed to clarify the efficacy of prenatal treatments for certain infections.
