title: Thyroid hormone levels in children with liver cirrhosis awaiting a liver transplant.
abstract: OBJECTIVE
  Evidence exists that decreased in triiodothyronine (T3) and thyroxine (T4) levels are associated with the severity of liver disease, and these hormones could be used as disease prognostic factors, but there are paradoxes in this regard in the literature. This study aimed at evaluating the correlation between thyroid hormone levels and severity of liver disease.
  
  
  METHODS
  We measured thyroid hormone levels in 83 children with liver cirrhosis using radioimmunoassay techniques.
  
  
  RESULTS
  Four patients (4.8%) showed a decrease in the amount of T3 and 9 patients (10.8%) revealed increased levels of T3. Also, decreases were seen in the T4 levels of 7 patients (8.4%), and 4 patients (4.8%) showed increases in levels of T4. The serum albumin levels were lower and international normalized ratio was higher in patients with low T3 and low T4. This study reveals that the Model for End-Stage Liver Disease and Pediatric End-Stage Liver Disease scores are statistically related to the decreased amounts of T4 (P = .036). The Model for End-Stage Liver Disease and Pediatric End-Stage Liver Disease scores and the Child scores were higher in low T3 patients, but this was not significant (P > .05).
  
  
  CONCLUSIONS
  Decreased levels of thyroid hormones are correlated with the severity of disease and can be seen in more advanced cirrhosis. Patients with decreased T4 levels need a liver transplant more immediately than those patients that do not have decreased T4 levels.
