title: A report of three cases of jaundice with thyrotoxicosis.
abstract: BACKGROUND
  Jaundice and hepatic dysfunction have been reported in patients with thyrotoxicosis and could be due to different mechanisms.
  
  
  OBJECTIVE
  To describe three cases of jaundice occurring in patients with thyrotoxicosis and to illustrate the importance of early institution of thionamides when indicated.
  
  
  METHODS
  We present the clinical and laboratory features of three patients presenting within a year with thyrotoxicosis and jaundice and whose clinical conditions improved remarkably following treatment with thionamides. In addition, current literature on the subject is reviewed and summarised.
  
  
  RESULTS
  The three patients presented with goitre and jaundice. None of the patients had received blood products, undergone scarification markings or experienced any previous episode of jaundice. Thyroid function tests in the three patients were consistent with a diagnosis of thyrotoxicosis. Liver function tests showed elevated bilirubin and transaminases. All patients improved remarkably following treatment with thionamides.
  
  
  CONCLUSIONS
  It is important to rule out thyrotoxicosis in patients with jaundice of unknown cause and consider early use of thionamides for treatment of the thyrotoxicosis, if confirmed.
