We have shown, in animal models as well as in retrospective human study, th
at some degree of decreased thyroid function is beneficial for subjects wit
h liver damage of various etiologies. Therefore, we herein present the resu
lts of a cohort population study. Between 1991 and 1994, 18 patients (12 wo
men and 6 men; mean age, 59 +/- 24 years) with both biopsy-proven active ci
rrhosis (5 hepatitis C virus, 4 hepatitis B virus, 1 immunocompromised host
, 2 primary biliary cirrhosis, 1 alcoholic, and 5 cryptogenic; Child's-Pugh
criteria: A-8, B-8, C-2) and primary or induced (by either drug or surgery
) thyroxine-treated hypothyroidism were prospectively followed. Each patien
t was examined at least twice yearly and served as their own control. The t
hyroid of the profiled patients ranged between euthyroidism and subclinical
hypothyroidism. Liver function tests were evaluated and compared in states
of normal versus increased thyroid-stimulating hormone (TSH) blood levels.
A significant improvement in alanine aminotransferase (p < 0.001), alkalin
e phosphatase (p < 0.0001), albumin (p < 0.001), and bilirubin (p < 0.01) w
as found in the increased TSH group. Prothrombin time was also found to be
significantly better (p < 0.001). We conclude that euthyroid patients with
liver cirrhosis might benefit from a controlled hypothyroidism.
