Abstract
Antithyroid drugs (ATDs) have been widely and effectively used for the treatment of pediatric and adult thyrotoxicosis for more than a half century. Since the very beginning of ATD use, reports of hepatic dysfunction related to propylthiouracil (PTU) therapy have been published. We describe a case of a 12-year-old girl, who, after 4 weeks of therapy for Graves disease (GD) with PTU (300 mg/day at 100 mg given three times a day), developed fatigue, fever, diarrhea, nausea, and vomiting. The initial diagnosis was “viral gastrointestinal infection”. Few days after the initiation of her symptoms, the patient developed jaundice, hepatic tenderness, and dark urine. She was admitted to the hospital where, after an extensive investigation, it was found that serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT) were elevated (2312 and 1435 IU/L, respectively), alkaline phosphatase (ALP) was 171 IU/L and total bilirubin was 12.7 mg/dL, whereas direct bilirubin was 7.6 mg/dL and prothrombin time was 23.2 s (normal ratio, <14.5 s). Serology for hepatitis A and B was negative. The diagnosis of PTU-induced hepatitis was established. PTU was discontinued, and a treatment with prednisone (50 mg/day) and vitamin K was initiated. Four weeks after admission, her hepatic tests returned to normal. We searched the English literature and we present details of all cases with PTU-related hepatic toxicity in children and adolescents published so far. Also, we provide information regarding the mechanisms and treatment of this appalling clinical entity. Finally, after recent recommendations from American Thyroid Association (ATA) and European Thyroid Association (ETA), PTU should be administered only in the first trimester of pregnancy and in cases of drug allergy to methimazole.
