Researchers in China have discovered in a new study that histamine H2 receptor blockers common acid reflux drugs may be a new treatment option for hypoxic-ischemic encephalopathy.It may turn out to be a potential way to prevent a lack of oxygen or blood flow from causing long-lasting brain damage in newborn children.
The study has been published September 29 in the Journal of Experimental Medicine (JEM).
The research suggests that targeting the histamine H2 receptor with drugs already used to treat acid reflux in infants could help newborns recover from hypoxic-ischemic encephalopathy (HIE), a condition that affects over 1 in 1,000 live births and can cause life-long neurological disabilities.
HIE can develop during pregnancy or from complications during labor and delivery. Premature infants also have a high risk of the disorder, in which disruptions to the oxygen and blood supply damage the brain's white matter, primarily composed of fat-producing oligodendrocytes that insulate and protect the brain's nerve cells. This can cause severe and long-lasting neurological disabilities, including cerebral palsy, epilepsy, and cognitive impairment. Researchers suspect that some of these symptoms could be alleviated if oligodendrocyte precursor cells could be prompted to form new oligodendrocytes capable of restoring the lost white matter.
"However, very few drug targets capable of inducing oligodendrocyte formation have been identified," says Weiwei Hu, a professor at Zhejiang University School of Medicine in Hangzhou and the senior author of the new study.
Hu and colleagues found that a protein known as the histamine H2 receptor inhibits the formation of mature oligodendrocytes capable of restoring the brain's white matter after injury. Mice lacking the histamine H2receptor recovered better from neonatal hypoxia-ischemia, regenerating more of their white matter and showing improved motor skills and cognitive function.
Cimetidine and other drugs that target the histamine H2 receptor are already used to treat acid reflux in newborn children. Hu and colleagues found that treating mice with cimetidine also improved the animals' recovery from hypoxia-ischemia. Crucially—given that HIE is often only diagnosed several months after birth—even delayed treatment with cimetidine was effective in restoring the mice's white matter.
"Given the present application of histamine H2 receptor blockers in preterm and full-term infants, our study suggests that they could also be a safe and effective treatment for neonatal HIE," Hu says.
