WSU mice assist with therapies for preventing pre-term birth
Preterm birth is the leading cause of neonatal mortality worldwide. One out of four preterm infants are born to a woman with an intra-amniotic infection or inflammation process, yet there is no clinical treatment for this condition. In Drs. Jose Galaz and Nardhy Gomez-Lopez (et al.) recent 2022 paper, “Clarithromycin prevents preterm birth and neonatal mortality by dampening alarmin-induced maternal-fetal inflammation in mice”, they investigated the potential therapeutic effects of clarithromycin on adverse neonatal outcomes in mice. The importance of this relationship is in a potential treatment and prevention for preterm birth and the results have been featured by the National Institutes of Child Health and Human Development.
Their data suggest that clarithromycin reduces the placental inflammation induced by an intra-amniotic protein (HMGB1), providing a potential mechanism to improve neonatal survival. Treatment with clarithromycin dampened inflammation in fetal mouse tissues, namely lung, intestine, and liver. According to Dr. Jose Galaz, “Clarithromycin is a macrolide antibiotic that is approved to be used in pregnant women, and thus our results support the potential use of clarithromycin to treat pregnant women with sterile intra-amniotic inflammation.” This paper represents the first published evidence showing the anti-inflammatory effects of clarithromycin on intra-amniotic inflammation and neonatal survival and has potentially important implications for preterm labor and birth.
