About our research
Miscarriage affects 1 in 6 pregnancies and causes untold emotional and physical pain to couples across the world. We are conducting a broad Programme of work to better understand the causes of miscarriage and testing new treatments to prevent miscarriage, underpinned by the National Tommy’s Centre for Miscarriage Research, led by Coomarasamy and spanning across UoB, University of Warwick and Imperial College London.
Through a series of large multi-centre trials, Coomarasamy & team have achieved major breakthroughs, resulting in 3 NEJM publications in 2019 alone, and 5 NEJM papers in the last 3 years. This includes the PRISM trial, the largest ever miscarriage trial recruiting >4100 patients from 48 UK hospitals, which found that progesterone treatment increases live birth rate in women with early pregnancy bleeding and a history of previous miscarriages, with huge implications for practice.
The TABLET trial (Coomarasamy, Dhillon-Smith) aimed to test whether levothyroxine reduces the risk of miscarriage in women who have thyroid antibodies. The study found no benefit from this treatment, an important finding that should stop the unnecessary use of this treatment, a common practice in infertility clinics. We also explore the role of cell-free fetal DNA sequencing to investigate for chromosomal problems in the fetus (Kilby), the role of sperm DNA fragmentation in miscarriage risk (Kirkman-Brown), and the association between immune markers, placentation and miscarriage (Tamblyn, Hewison, Kilby).
