Signal of increased risk of neural tube defects
An EU review has begun following preliminary results from an observational study suggesting an increased risk of neural tube defects in infants born to women who took dolutegravir at the time of conception.
The study, which looked at babies born to 11,558 women with HIV in Botswana, showed that 0.9% of babies (4 of 426) whose mothers became pregnant while taking dolutegravir had a neural tube defect, compared with 0.1% of babies (14 of 11,173) whose mothers took other HIV medicines. No cases were reported in infants born to women who started dolutegravir later during pregnancy. Final results of the study are expected in about a year. The review will also investigate cases of birth defects in babies born to women who took dolutegravir during pregnancy reported, including two in the USA
