Chlamydia could be linked to birth problems

University of Edinburgh scientists are behind new findings that suggest a link between an increased risk of pregnancy outside the uterus, so called ectopic pregnancy, and chlamydia.

The study, funded by Wellbeing of Women, found that higher levels of a protein called PROKR2, which is linked to ectopic pregnancies, were found in the fallopian tubes of women who had previously had the sexually transmitted infection, compared to women with no evidence of the infection.

An ectopic pregnancy occurs when the ovum is implanted in the fallopian tubes instead of in the uterus, often causing internal bleeding, maternal mortality in the first trimester of pregnancy, or future fertility problems.

Chlamydia is the most commonly diagnosed sexually transmitted infection, however, unlike some other infections, it usually presents no symptoms. Early diagnosis and treatment of chlamydia can reduce the risk of fertility problems, therefore making it even more important for young females to be tested.

Statistics released by NHS Scotland at the end of 2010 show that almost three out of four new diagnoses of chlamydia occur in the under-25 age group. The test for chlamydia is confidential and non-invasive and can be carried out at your nearest GP surgery or sexual health clinic.

The study, which was published in the American Journal of Pathology, follows on from previous research at the university which found that women who smoke also have an increased risk of ectopic pregnancy by producing a similar protein called PROKR1.

Dr Andrew Horne, of the University of Edinburgh’s Centre for Reproductive Biology, told The Journal that there were "no plans at the moment to investigate possible links between other sexually transmitted infections and ectopic pregnancy."
