The presence of Anti-Thyroid antibodies (ATAs) alone [subclinical hypothyroidism] has also been shown to have adverse pregnancy effects. These can result in failure to conceive, recurrent miscarriages, anemia, preeclampsia, and abruption. Hashimoto's disease in reproduction can cause difficulty in conception through hormonal interference. It can also cause miscarriages, growth retardation, and preterm birth. The current recommended treatment is the administration of levothyroxine. This corrects the thyroid balance and may relieve the patient's hypothyroid symptoms.

The small for gestational age (SGA) rate was 30.8% and the stillbirth rate was 11.5% in the APS group (<i>p</i> = 0.017, <i>p</i> = 0.001). The optimum cutoff values for SGA were 584.97 (75% sensitivity, 77.8% specificity), 688.50 (62.5% sensitivity, 62.9% specificity), and 1.02 (56.3% sensitivity, 77.8% specificity) for SII 1, SII 2, and SIRI 1, respectively. The optimum cutoff value for stillbirth was 1.23 for SIRI 2 (83.3% sensitivity, 89.1% specificity, <i>p</i> = 0.004).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>Pregnant women with APS had decreased blood indices in the first trimester and the last month before birth compared to the control group. In cases with APS, these indices can predict APOs like SGA and stillbirth.</p>\u0000 </section>\u0000 </div>","PeriodicalId":7665,"journal":{"name":"American Journal of Reproductive Immunology","volume":"93 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142909011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
