ABSTRACT
A doença celíaca representa uma enteropatia inflamatória crônica do intestino delgado, imunomediada, que ocorre como resposta a uma intolerância permanente ao glúten em pessoas geneticamente predispostas. Essa doença tem várias manifestações clínicas, pode ser assintomática, e em gestantes celíacas não diagnosticadas tem sido associada a risco aumentado de recémnascidos com baixo peso ao nascer. Esta revisão tem como objetivo fornecer uma melhor compreensão dos mecanismos fisiopatológicos envolvidos na associação entre doença celíaca materna e baixo peso ao nascer por meio de uma revisão bibliográfica das publicações mais relevantes no tema nos últimos 20 anos.(AU)
Celiac disease is a chronic, immunemediated, inflammatory disorder of the small intestine, that occurs in response to a permanent intolerance to gluten in genetically predisposed individuals. Its clinical manifestations may vary significantly, including an asymptomatic presentation. In undiagnosed celiac pregnant women, it has been associated with increased risk of low birth weight newborns. This review aims to provide a better understanding of the pathophysiological mechanisms involved in the association between maternal celiac disease and low birth weight through a literature review of the most relevant publications on the subject in the last 20 years.(AU)

Objetivo: Revisar os dados já publicados sobre a associação entre doença celíaca materna e desfechos gestacionais desfavoráveis (nascimento de recémnascidos com baixo peso, prematuros e pequenos para idade gestacional) e sua relação com a dieta isenta em glúten. Fontes dos dados: Revisão sistemática feita nas bases de dados do PubMed e da Biblioteca Virtual em Saúde. Incluídos estudos de coorte que compararam a incidência de desfechos gestacionais desfavoráveis em mulheres com doença celíaca tratadas e não tratadas com dieta isenta em glúten. A validade interna dos estudos foi avaliada pelos critérios Strobe. Síntese dos dados: Doença celíaca materna não tratada esteve associada ao nascimento de recémnascidos de baixo peso, prematuros e pequenos para a idade gestacional. Quando tratada, o risco desses desfechos se aproximou do encontrado na população sem doença celíaca. Conclusões: Doença celíaca materna não tratada esteve associada a desfechos gestacionais desfavoráveis. A dieta isenta em glúten parece aproximar o risco desses desfechos ao encontrado em mulheres saudáveis.(AU)
Aim: To review the published data on the association between maternal celiac disease and adverse pregnancy outcomes and its relationship to glutenfree diet. Sources: A systematic review of Biblioteca Virtual em Saúde (LILACS, IBECS, MEDLINE, SciELO, and Cochrane) and PubMed databases was performed. Cohort studies that compared the incidence of adverse pregnancy outcomes in women with treated and untreated celiac disease were included in the analysis. STROBE criteria was used to assess the internal validity of the studies. Summary of the findings: Maternal untreated celiac disease was associated with premature births, low birthweight and small for gestational age. When celiac disease was treated, the risk of these outcomes was similar that found in people without celiac disease. Conclusions: Untreated maternal celiac disease was associated with adverse pregnancy outcomes. Treatment with glutenfree diet reduced significantly the risk of these outcomes, making the rate similar to that observed on women without celiac disease.(AU)

OBJECTIVE: To determine the prevalence of celiac disease in a group of Brazilian women with infertility. STUDY DESIGN: This was a cross-sectional study of 170 infertile Brazilian women tested for immunoglobulin A anti-tissue transglutaminase (IgA anti-tTG), endomysial antibody and total IgA. Women with positive serologies were recommended for intestinal biopsy. Patients with positive serology and villous atrophy on biopsy had the diagnosis of celiac disease, while those with positive serology but no villous atrophy were identified as having latent celiac disease. All of these women were typed for HLA-DQ2 and HLA-DQ8. RESULTS: The prevalence of celiac disease confirmed by biopsy in the study group was 1.2% (2 out of 170) (95% confidence interval [CI], 0.1-4.2). Considering also those with latent celiac disease, the prevalence was estimated at 2.9% (5 out of 170) (95% CI, 1.0-6.7) and in the subgroup of unexplained infertility the prevalence was 10.3% (3 out of 29) (95% CI, 2.2-27.4). All seropositive patients were also HLA-DQ2 positive. CONCLUSION: Further studies are required to define the role of routine serological screening for celiac disease in infertile women as well as to elucidate the underlying mechanism for infertility in active celiac disease.
