The researchers at the University of Leicester claims to have discovered a predictor that could warn about pregnancies with possible miscarriages.
This predictor, they say, is the level of a naturally occurring ‘cannabis’ (an endocannabinoid) known as anandamide.
The researchers, led by Professor Justin Konje, found that women who had higher levels of anandamide during the course of their pregnancy had a greater chance of miscarrying.
He and his team had previously reported that the levels of these endocannabinoids fall during the early period of pregnancy and rise towards term.
He said: “We are extremely excited by these findings. Essentially, we have for the first time been able to use the levels of this naturally occurring cannabis, anandamide in 45 women presenting with threatened miscarriage and a viable pregnancy to predict the eventual outcome of the pregnancy.”
“Using a threshold we defined from this study, we were able to predict all the women who then went on to have a subsequent miscarriage and 94 percent of those who went on to have a live birth.
“This is the first time that this has been reported. It has very significant implications and if the results are replicated, we would eventually be able to reassure women who present with bleeding in early pregnancy about the outcome of their pregnancies.
“Obviously for those whose pregnancies are identified by this measurement as destined to end in a miscarriage, knowing this may cause grief and upset but it may also help them to come to terms quickly with the outcome of the pregnancies.
