Comparison of celiac disease markers in women with early recurrent pregnancy loss and normal controls.

Abstract

Celiac disease (CD) is an autoimmune intestinal inflammatory disease triggered by gluten in the diet. Untreated CD has been associated with pregnancy loss and infertility. The purpose of this study was to screen unselected women with recurrent pregnancy loss (RPL) for markers of CD to determine whether a correlation exists between RPL and CD serum markers. Frequencies of three serum markers of CD [tissue transglutaminase (TTG) IgA, endomysial (EMA) IgA, and deaminated gliadin peptide (DGP) IgA] were determined by enzyme-linked immunoassay (ELISA). Seven hundred and eight women who had two or more failed clinical pregnancies (cases) and one hundred women with at least one live birth and no miscarriages (controls) were included in this study. All cases had a full workup for RPL based on the American Society for Reproductive Medicine 2013 guidelines. Antiphospholipid antibodies (aPL) were correlated with CD markers based on their potential prothrombotic role. Results The results show no significant difference in the prevalence of CD autoantibodies when comparing the RPL patients with the controls. Over half of the patients who tested positive for serum markers for CD also had positive aPL. Conclusion Screening unselected women with RPL who are asymptomatic for CD is not supported based on these data. Women who test positive for CD may be candidates for aPL testing based on the association of adverse pregnancy outcomes.
