title: Serum creatine phosphokinase in thyroid disorders.
abstract: The decreased serum levels of triiodothyroinine (T3) and thyroxine (T4) in hypothyroid patients is well established but whether there is any correlation of creatinephosphokinase (CPK) with hypothyroidism is not well established. There is a paucity of reference on this study. Therefore a study of serum CPK and thyroid profile was carried out in thyroid diseases. In hypothyroid patients T3, T4 levels in serum were found to be lowered with an increase level of thyroid stimulating hormone (TSH) associated with marked rise in serum CPK level. In hyperthyroid patients serum levels of T3, T4 were found to be increased with decrease in TSh with significant decrease in creatine phosphokinase level. Serum creatine phosphokinase levels thus show an inverse relation with serum T3, T4 levels.
