Cholestatic hepatitis is a rare presentation of thyrotoxicosis potentially confused as an adverse effect of antithyroid therapy. We report a 37-year-old man with cholestatic hepatitis as an initial presentation of Graves' disease. Diagnostic evaluation demonstrated (i) elevated transaminases and alkaline phosphatase (R-factor value: 2.6), and marked cholestasis (total bilirubin: 17.3 mg/dL, direct bilirubin: 9.4 mg/dL); (ii) negative hepatitis, viral, and autoimmune serologies; (iii) normal magnetic resonance cholangiopancreatography; (iv) liver biopsy with marked cholestasis and no fibrosis; (v) thyroid-stimulating hormone <0.01, fT4 (free thyroxine): 1.5, fT4 (free triiodothyronine): 4.3 and positive thyroid-stimulating immunoglobulins. Radioiodine uptake scan confirmed Graves' disease. Clinical resolution was achieved with propranolol, prednisone, methimazole, and thyroidectomy.
胆汁淤积性肝炎是甲状腺毒症的一种罕见表现,可能会被误诊为抗甲状腺治疗的不良反应。我们报告一名37岁男性,以胆汁淤积性肝炎作为格雷夫斯病的首发表现。诊断评估显示:(i)转氨酶和碱性磷酸酶升高(R因子值:2.6),且有明显胆汁淤积(总胆红素:17.3mg/dL,直接胆红素:9.4mg/dL);(ii)肝炎、病毒及自身免疫血清学检查均为阴性;(iii)磁共振胰胆管造影正常;(iv)肝活检显示明显胆汁淤积且无纤维化;(v)促甲状腺激素<0.01,游离甲状腺素(fT4):1.5,游离三碘甲状腺原氨酸(fT3):4.3,甲状腺刺激免疫球蛋白阳性。放射性碘摄取扫描确诊为格雷夫斯病。通过普萘洛尔、泼尼松、甲巯咪唑及甲状腺切除术实现了临床缓解。
