  • Title: Unexplained Infertility and Undiagnosed Celiac Disease: Study of a Multiethnic Canadian Population.
    Author: Gunn B, Murphy KE, Greenblatt EM.
    Journal: J Obstet Gynaecol Can; 2018 Mar; 40(3):293-298. PubMed ID: 29132967.
    Abstract:
    OBJECTIVE: The aims of this study were to examine the prevalence of Celiac disease (CD) in Canadian women with unexplained infertility versus women with an identifiable cause of infertility and to assess the sensitivity of the point-of-care Biocard Celiac Test Kit versus standard serum serologic testing. METHODS: In this prospective cohort study, women aged 18 to 44 who were evaluated for infertility between February 2010 and May 2012 at a tertiary academic care fertility clinic in Toronto, ON, were invited to participate. They were categorized as having unexplained infertility (Cases) or infertility secondary to a known cause (Controls). Women on a gluten-free diet or previously diagnosed with CD were excluded. Outcome measures were the Celiac Questionnaire, serum testing for tissue transglutaminase IgA antibody (anti-tTG IgA), serum IgA levels, and Biocard Celiac Test Kit. RESULTS: Of 685 women approached, 1.2% (4/326) with unexplained infertility and 1.1% (4/359) with an identifiable infertility cause were newly found to have CD. Biocard testing revealed the same results as standard serologic IgA and anti-tTG IgA testing. CONCLUSION: CD was not more common in women with unexplained infertility than those with an identifiable cause of infertility. These results do not support the routine screening of Canadian women with infertility for CD.
