Six patients were admitted after erroneous massive intake of levothyroxine (70-1200 mg over an interval of 2-12 days). All patients developed classical symptoms of thyrotoxicosis within 3 days of the first dose; five patients presented grade II-III coma and one became stuporous (days 7-10). Two patients developed left ventricular failure and three had arrhythmias (days 8-11). Total thyroid hormone levels in serum on admission ranged 935-7728 nmol/l for T4 (TT4) and 23-399 nmol/l for T3 (TT3). All patients received treatment with hydrocortisone and Propranolol. Propylthiouracil was also given in 3 cases. Extractive techniques (charcoal haemoperfusion and/or plasmapheresis) were initiated 8-14 days after the first dose of L-T4. The plasma disappearance rate (K) of TT4 with plasmapheresis was 30 times higher, on average, than under standard medical treatment (M). Also, K of TT4 under haemoperfusion was about five times higher than K under M. K changes for TT3 were higher under haemoperfusion than under plasmapheresis. Furthermore, extractive procedures shortened the average half life of TT4, (from 106.5 +/- 44.6 to 59.7 +/- 20.2 h, p less than 0.05).

Propylthiouracil (PTU) is widely used to treat patients with hyperthyroidism. In rare cases, this drug has been found to have severe toxic effects on the liver. The case of a 14-year-old girl treated with PTU for hyperthyroidism who developed jaundice, severe hepatocellular dysfunction, and hepatomegaly is reported. Her condition gradually deteriorated, and she developed paranoid ideation, profound lethargy, and peripheral edema. After three weeks of prednisone therapy, clinical and laboratory signs of improvement were observed. This patient was one of only five pediatric cases among the 16 reported cases of PTU liver toxicity reported to date. Her history and the fatal outcome in some reported cases demonstrate the high degree of sensitivity required to recognize this potential complication in patients treated with PTU, particularly since its immediate discontinuance and steroid-therapy intervention may lead to recovery.

A 65-year-old woman presented to the hospital with weight loss and diarrhea. A diagnosis of thyroid storm was established by the presence of fever, lethargy, tachycardia, heart failure (HF), and abnormal thyroid function tests. An acute coronary syndrome (ACS) was suspected because of anteroseptal ST-segment elevations on electrocardiogram and severe left ventricular (LV) dysfunction with apical dilation on echocardiogram. The ejection fraction (EF) was 25%. Treatment for ACS and HF was begun. Coronary arteriography revealed normal coronaries. Propylthiouracil and corticosteroids were added to treat thyrotoxicosis. On Day 4, repeat echocardiography confirmed an EF of 65% and complete resolution of LV dysfunction and cavity dilation. Reversible LV dysfunction and apical cavity dilation is consistent with Takotsubo cardiomyopathy. While commonly associated with psychological trauma, its association with thyroid storm has only been reported twice before. Knowledge of this possible association is of importance in establishing the diagnosis and instituting a proper treatment plan.
