Study Summary

Preterm delivery (PTD), together with low birthweight (LBW), is the leading cause of infant death and illness, affecting 500,000 births with annual medical costs of more than $26 billion in the U.S. each year. Identifying changeable risk factors to reduce PTD is considered a top research priority. Recent research has shown genital herpes infection (HSV) is associated with increased risks of PTD and LBW. More importantly, treating this infection, including infection with no symptoms, using readily available antiviral medications can be effective in removing the risk due to HSV. Thus, early identification and treatment of HSV in pregnant women could be an effective way to prevent PTD and LBW. Currently, many pregnant women with HSV infection, especially those with no symptoms, choose not to treat due to (a) a lack of demonstrated benefit of treatment and (b) general hesitance to use medications during pregnancy due to safety concerns for the fetus. Thus, emerging evidence of an increased risk of PTD/LBW associated with HSV infection, if untreated, and treatment effectiveness by anti-herpes medications has significantly changed current treatment paradigms among pregnant women. This evidence also provides new hope that effectively treating HSV infection among pregnant women, especially before the 3rd trimester, could lead to a new method to reduce PTD and LBW and reduce racial/ethnic disparities in these risks due to high rates of the infection in minority groups. To further examine the effectiveness of treating HSV in pregnant women to reduce adverse pregnancy outcomes, the investigators propose to conduct a prospective cohort study with a two-stage design combining the large pregnant women population (N=90,000) in Stage I identified through Kaiser Permanente Northern California (KPNC) electronic medical records (EMRs), with a Stage II sample to collect detailed information on additional factors that might muddle our understanding of this issue.
