Puerperal and perinatal infections with group B streptococci

Area of Science:

• Obstetrics and Gynecology
• Infectious Diseases
• Neonatal Health

Background:

• Group B streptococci (GBS) is a significant cause of puerperal and perinatal infections.
• A high incidence of GBS carriage is noted in the studied population.
• Puerperal sepsis and GBS infections pose risks to both mothers and newborns.

Purpose of the Study:

• To investigate the incidence and clinical features of puerperal sepsis and other GBS infections.
• To identify risk factors associated with GBS infections in parturients.
• To evaluate the impact of GBS infections on neonates.

Main Methods:

• Retrospective review of 21 patients with puerperal sepsis due to GBS.
• Analysis of 47 patients with non-bacteremic GBS infections, including endometritis, amnionitis, and UTIs.
• Examination of GBS infections in seven neonates and potential intrauterine or fetal exposure.

Main Results:

• An attack rate of 2/1,000 deliveries for GBS puerperal sepsis was observed.
• Abdominal delivery, endometritis, and puerperal sepsis showed a strong association.
• GBS was frequently detected in birth canal/lochia cultures matching blood serotypes; neonates and mothers experienced severe infections.

Conclusions:

• High rates of puerperal and perinatal GBS infections necessitate further investigation.
• Antibiotic prophylaxis regimens may be beneficial in populations with high GBS incidence.
• Early identification and management of GBS infections are crucial for maternal and neonatal outcomes.
