New womb lining test can help women who have miscarriages, UK scientists say
A new test that reveals an abnormal womb lining can help women who have repeated unexplained miscarriages, UK scientists have said. They say the findings are set to pave the way for new treatments for some women who experience recurrent pregnancy loss. Researchers said they discovered that miscarriage risk can be traced back to a problem with the womb lining before pregnancy, after previous studies mostly focused on the quality of the embryo, overlooking the role of the womb. Around one in six pregnancies are lost, mostly before 12 weeks, and each miscarriage increases the risk of another pregnancy loss. Pregnancy and baby charity Tommy's said the discoveries are set to provide explanations for pregnancy loss as well as treatments to prevent the 'trauma and devastation of recurrent miscarriage'. Lead author Dr Joanne Muter said: 'This is about identifying preventable miscarriages. Many women are told they've just had 'bad luck', but our findings show that the womb itself may be setting the stage for pregnancy loss, even before conception takes place.' The study – led by the University of Warwick and University Hospitals Coventry and Warwickshire (UHCW) NHS Trust with funding from pregnancy charity Tommy's – was published in Science Advances on Thursday, after over 1,500 biopsies from more than 1,300 women were analysed. The team found that an essential biological process called the 'decidual reaction', which prepares the womb lining for pregnancy each month, often does not progress properly in women with a history of miscarriage. This creates an unstable environment that, while still allowing embryos to implant, increases the risk of bleeding and early pregnancy loss. The scientists have consequently developed a test that can measure the womb lining response, which is being piloted to support more than 1,000 patients at Tommy's National Centre for Miscarriage Research at UHCW. Senior author Professor Jan Brosens said: 'It is well-established that chromosomal errors in embryos account for the rise in miscarriage rates in women older than 35 years. This study shows that each miscarriage increases the risk of an embryo implantation in an abnormal womb lining, regardless of age. 'Thus, the frequency of one of two events – abnormal embryo or abnormal decidual reaction – happening over hundreds of menstrual cycles determines the likelihood of miscarriage in each individual woman. Importantly, we now have the tools to screen for the risk of preventable miscarriage and to evaluate treatments that improve the womb lining before pregnancy.' Holly Milikouris, who has had five miscarriages, described the new test as 'life changing'. After it was revealed that her womb lining prepared abnormally for pregnancy, she underwent treatment and went on to have two healthy children, three-year-old George and 17-month-old Heidi, with her husband Chris. Ms Milikouris, a civil servant from Cheshire, said: 'My miscarriages were all 'missed', which means there were no symptoms to let us know there was a problem. We found out when I went for a scan and a grew to dread having scans. 'We felt lost and were beginning to accept that I might never successfully carry a pregnancy. The treatments that typically can help women who have experienced miscarriages hadn't worked for us and each time we tried again we felt like we were rolling a dice with the baby's life. 'Being given the opportunity to take part in this trial was life changing. For the first time the results of my biopsy were normal, and we went on to have not one, but two successful pregnancies. We will never be able to thank Professor Brosens enough and are hopeful that the results of this groundbreaking study will help many other families.'

Womb lining test offers miscarriage hope to women
UK scientists say they have developed a test which can help identify women with an abnormal womb lining that increases their risk of miscarriage. They say their work could pave the way for new treatments for those going through repeated pregnancy loss. In some women with a history of miscarriage, the womb lining doesn't react the way it should - transforming into a supportive place for the embryo to implant, the Warwick University team discovered. Charities say the findings could help provide an explanation, in some cases, for the trauma and devastation of recurrent miscarriage. Around one in six of all pregnancies are lost, most before twelve weeks, and each miscarriage increases the risk of another one happening. To date, most research in this area has focused on the quality of the embryo, with much less known about the role of the womb lining. Dr Jo Muter, study author and researcher at Warwick Medical School, said: "Many women are told they've just had 'bad luck', but our findings show that the womb itself may be setting the stage for pregnancy loss, even before conception takes place." The job of the womb lining is to receive the embryo and help it develop during pregnancy, thanks to a reaction which converts cells into a different, supportive state. But when that reaction is messed up and doesn't fully happen, the risk of bleeding and early pregnancy rises. Once a woman has had one faulty reaction, she is more likely to have another, the researchers say. They've developed a new test which can measure signs of a healthy or defective reaction in the womb lining, which is being piloted to help more than 1,000 patients at Tommy's National Centre for Miscarriage Research at University Hospital Coventry & Warwickshire (UHCW). Charlie Beattie, 37, had countless early miscarriages over the course of four years, to the point where "a positive pregnancy test wasn't exciting any more", she says. She and her husband Sam, from Leamington Spa, felt devastated and resigned to considering other options for having a family. Then they found out about at a trial taking place at the miscarriage research centre. Charlie had a sample of her womb taken, and the new test showed it was not "hospitable for babies", she says. After taking the drug sitagliptin for three months, she had a pregnancy which finally stuck - and nine-week-old June is the joyful result. "She's a tiny miracle. It doesn't feel real," says Charlie. She admits being anxious all the way through her pregnancy until June was safely in her arms. Even the pregnancy scans were a new experience. "We'd never seen anything on a scan before that moved," she says. "When they said 'I can see it, it's in the right place', we both burst into tears." Anyone can refer themselves to the clinic, but it has a long waiting list and funding issues mean patients must contribute to the cost of the test. Dr Jyotsna Vohra, director of research at Tommy's, said care and treatment for those who experience pregnancy or baby loss varied unacceptably across the UK. "There should be no barriers to accessing any test or treatment that has been proven to make a difference. "We hope NHS decision-makers will look carefully at the results of the Coventry pilot project and consider rolling this test out nationwide, so that everyone who might benefit has that opportunity." Dr Muter says the next step is to use the test to assess potential drug treatments. Sitagliptin, usually used to treat diabetes, is the go-to option for womb lining issues but there may be other existing drugs which can be repurposed, she added. With 80% of drugs not tested on pregnant women, it's unclear which ones might be effective.
