We report a case of a 21-year-old young woman who was initially diagnosed with hyperthyroidism secondary to Graves' disease and spontaneously switched to hypothyroidism in a year. While most autoimmune hypothyroidism is due to Hashimoto's disease, in her case, we suspect that her hypothyroidism is due to a switch of antibody dominance from thyroid stimulating hormone (TSH) receptor-stimulating antibody (TS Ab) to TSH receptor-blocking antibody (TB Ab). Switching from dominant TS Ab activity to dominant TB Ab activity is a rare phenomenon. Optimal management of this condition is not known. Loss of follow-up and medication non-adherence has made medical management in this young woman of reproductive age further challenging.
我们报告了一例 21 岁年轻女性的病例，她最初被诊断为格雷夫斯病引起的甲状腺功能亢进症，并在一年内自发转变为甲状腺功能减退症。虽然大多数自身免疫性甲状腺功能减退症是由于桥本氏病引起的，但在她的情况下，我们怀疑她的甲状腺功能减退症是由于甲状腺刺激激素（TSH）受体刺激抗体（TSAb）到 TSH 受体阻断抗体（TBAb）的抗体优势转换引起的。从主要的 TSAb 活性转变为主要的 TBAb 活性是一种罕见现象。这种情况下的最佳治疗方法尚不清楚。由于失去随访和药物依从性，这位年轻的育龄女性的医学管理更加具有挑战性。
