THAA were identified as IgG-\u0138. During a first pregnancy that ended by miscarriage in the 3rd month, the titer of anti-thyroxine autoantibodies decreased by about 30%. Relapse of Graves\u2019 disease occurred 2 months later and an increase in serum THAA concentration to the initial titer was observed. THAA titer remained unchanged during treatment with methimazole and afterwards during thyroxine supplementation for radioiodine-induced hypothyroidism. During a second pregnancy, a decrease in anti-thyroxine autoantibody titer reached 45% at the time of delivery and an increase by 20% was noted 5 months later. A similar decline in THAA concentration was shown during a third pregnancy. The changes in THAA concentrations observed during pregnancy suggest an immunological influence of pregnancy on the THAA production, as previously demonstrated in other autoimmune diseases, like Hashimoto\u2019s thyroiditis.<\/jats:p>","DOI":"10.1159\/000181903","type":"journal-article","created":{"date-parts":[[2008,12,3]],"date-time":"2008-12-03T16:39:41Z","timestamp":1228322381000},"page":"205-207","source":"Crossref","is-referenced-by-count":3,"title":["Changes in Serum Thyroid Hormone Autoantibody Concentrations during Pregnancy: A Case Report"],"prefix":"10.1159","author":[{"given":"Roger","family":"Abs","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manou","family":"Martin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pierre","family":"Blockx","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2008,12,2]]},"container-title":["Hormone Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000181903","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T09:23:35Z","timestamp":1777627415000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000181903"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,12,2]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000181903","archive":["Portico"],"relation":{},"ISSN":["0301-0163","1423-0046"],"issn-type":[{"value":"0301-0163","type":"print"},{"value":"1423-0046","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008,12,2]]}}}
