Brenna L. Hughes, MD, MSc, of the Division of Maternal-Fetal Medicine and Director of the Women’s Infectious Disease program at Women & Infants Hospital presented at the 42nd Annual Meeting of the Infectious Diseases Society for Obstetrics and Gynecology (IDSOG) in Portland, OR. IDSOG brings together professionals in the field of obstetrics and gynecology who are interested in the scientific study of infectious diseases in women.

One of two poster presentations by the group took home the Best Poster Award, “Longitudinal cohort study of association of HIV infectivity with pregnancy.” The study examined epidemiologic data that currently conflicts as to whether pregnancy increases the risk of HIV acquisition. To measure this, the team compared the protection against infectivity conferred by cervicovaginal secretions among pregnant and non-pregnant women using a novel in vitro model.

The sample included 40 pregnant women with the mean gestational age of 12 weeks and 37 non-pregnant women. There were no significant differences between groups in most demographic characteristics. Pregnant women were followed across gestation and non-pregnant women across the menstrual cycle. Cervicovaginal lavage (CVL) was performed at each visit. CVL fluid from both groups significantly inhibited HIV infectivity compared to the control group.

“The median percent inhibition of HIV infectivity at enrollment did not differ between pregnant and non-pregnant women. The findings were similar at each follow-up visit and infectivity did not change significantly across time within groups,” said Dr. Hughes, who served as principal author on the study. “Our data doesn’t support the data saying that pregnant women are at higher risk of contracting HIV. This suggests that we need to study that question more thoroughly.”

Erica Hardy, MD, MA, MMSc, co-Director of the Women’s Infectious Disease program, served as presenting author for the second poster presentation “Uptake of Third Trimester HIV Testing Program at a Tertiary Care Hospital.” In addition, oral presentations at the meeting included “Inflammatory Mediators in Cervicovaginal Secretions and Association with HIV Infectivity among Pregnant and Non-pregnant Women,” Dr. Hughes as primary author. Catherine Albright, MD, fellow in the Division of Maternal Fetal Medicine, was the presenting author for the oral presentation “Use of Cefazolin for Group B streptococcus Prophylaxis in Women Allergic to Penicillin Without Anaphylaxis.”
