Preventing Viral Infections During Pregnancy

Dr. Michelle Silasi, Assistant Professor of Obstetrics, Gynecology, and Reproductive Sciences, will exam a efficacy of a new technique to shade for viral bearing during pregnancy that can brand women during risk for critical complications and concede for interventions to urge pregnancy outcomes. 

A Hidden Risk. Pregnant women competence not expose symptoms of an infection that could discredit their pregnancies.

“As we’ve seen with a new conflict of a Zika virus, viral infections during pregnancy poise critical threats to both a mom and a building fetus, that can fast turn a vital open health crisis,” Silasi said. “But there is now no effective, noninvasive, affordable process to exam for such exposures.” 

Inflammation signals an infection and can be totalled by an boost of a form of protein called interferon-gamma prompted protein of 10kDa, or IP-10. Silasi’s group will review levels of IP- 10 in stored samples of blood serum and swabbed vaginal secretions that had been collected during a prenatal revisit early in a second trimester of black women who went on to broach basic full-term pregnancies. Black women are an understudied and therefore underserved population. 

If a researchers learn that a levels are a same in a serum and vaginal secretions, health caring providers could discharge a need to pull blood from patients to exam for exposure, Silasi said. Instead, patients could simply bandage their possess secretions for screening during any prenatal visit, augmenting a luck of screening while dwindling cost.

A second idea of a investigate will engage comparing a levels of IP-10 in vaginal secretions collected in a early second trimester from both women who went on to broach during full tenure (between 39 weeks and 40 weeks and 6 days) and from women who delivered betimes before 35 weeks.

Elevated IP-10 levels in amniotic liquid during mid-trimester have been compared with preterm birth, though measurements need amniocentesis, an invasive procession that carries a risk of miscarriage. High IP-10 levels in a serum of profound women also have been compared with beforehand birth, though contrast requires some guess of infection, and women competence not expose symptoms.

“In other cases, women competence expose symptoms, though collecting samples can be time-consuming and costly, while not divulgence disease-specific results,” Silasi said. “We are carefree that by demonstrating a value of some-more simply performed vaginal secretions in detecting bearing to viruses, a investigate can lead to a adoption of a rapid, effective, specific, inexpensive, and noninvasive apparatus so we can improved caring for mothers and their fetuses.”

Women’s Health Research during Yale’s Pilot Project Program

The recipients of this year’s Pilot Project Program grants find answers to such questions as: 

  • Can a improved bargain of a colon’s digestive chemistry expose early signs and sex-specific causes of colon cancer to assist in impediment and diagnosis of this disease?
  • Can an affordable, rapid, noninvasive, and potentially self-administered exam accessible to profound women forestall a widespread of viral infections and preterm births?
  • Can a mobile phone app featuring an interactive character-based story assistance mangle a transgenerational cycle of insinuate partner violence?

“When it comes to biology and behavior, women and group are not identical,” pronounced Dr. Carolyn M. Mazure, Director of WHRY. “For a 20th year, WHRY is sparking creation with studies designed to rise a best practices for detecting and treating diseases and conditions that might impact women and group differently.”
