Several NICHD organizational units support and conduct research on BV and the diseases and conditions that are affected by it, including HIV/AIDS. In addition, the NICHD conducts research on areas relevant to BV such as infertility and contraception. A summary of some of these efforts follows.
Research supported by the NICHD's Pregnancy & Perinatology Branch (PPB) has included studies of BV in pregnant women. Several of these studies have been conducted by researchers in the Maternal-Fetal Medicine Units (MFMU) Network, and scientists from the Division of Intramural Population Health Research. A major focus of the Network's research has been on the ability of antibiotics, including clindamycin and metronidazole, to prevent preterm birth in pregnant women who test positive for BV but have no symptoms. Other research supported by the NICHD has included studies to identify maternal markers for predicting the likelihood of preterm delivery in pregnant women with BV.
The NICHD's Maternal and Pediatric Infectious Disease Branch (MPIDB) supports and conducts both domestic and international research into the epidemiology, natural history, pathogenesis, transmission, treatment, and prevention of HIV infection and its complications in infants, children, adolescents, pregnant women, mothers, women of childbearing age, and the family unit as a whole. These research areas are relevant to BV because BV increases a woman's likelihood of acquiring HIV/AIDS and passing HIV/AIDS on to a partner. In addition, because BV increases a woman's likelihood of acquiring HIV/AIDS, her fetus is at increased risk.
The NICHD's Contraceptive Discovery and Development Branch (CDDB) supports and conducts research and research training programs on reproductive health, epidemiology, and contraceptive technology. Major research areas include studies of new contraceptive methods; mechanisms of action and effects of contraceptive and reproductive hormones, drugs, devices, and procedures; optimal formulations and dosages of contraceptive agents, spermicidal microbicides, and hormone replacement therapies; post-marketing surveillance of reproductive products, devices, and procedures; and the health and fertility effects of reproductive drugs, devices, and procedures.
A woman's risk of developing BV is increased by having unprotected sexual activity. The many research areas supported by the CDDB, including contraception, are important for acquiring a complete understanding of BV. In addition, because BV can potentially increase the risk of co-infections that cause infertility, Branch-supported research on that topic provides valuable information on the health of women affected by BV.
The MMFMU Network, which is supported by the NICHD PPB, conducts studies of maternal and fetal medicine and obstetrics, with emphasis on the continuing problem of preterm birth. The Network has conducted clinical studies related to numerous areas of research, such as maternal health; fetal health and development; gestational diabetes, asthma, and thyroid disorders; and preterm labor.
Some of the studies conducted by MFMU Network researchers are directly relevant to the understanding of BV in pregnant women, particularly those who are asymptomatic. Among other topics, researchers have examined the efficacy of antibiotics for preventing preterm birth in pregnant women and the use of markers to predict preterm delivery.
