ABSTRACT
Objective To observe the change of serum thyroid peroxidase antibody(TPOAb) in the patients with Hyperthyroidism and Thyroid gland tumor of different phases.Methods The level of TPOAb was observed,the relation between the changed TPOAb level and reduced thyroid function was studied.Results Among 89 cases,50 cases had normal or slightly elevated TPOAb level.However,after treatment,31 cases showed a raised TPOAb level.Of 19 cases with hypothyroidism or its sub-clinical type.There were 39 cases with positive TPOAb.After the treatment,2 cases changed to negative TPOAb,26 cases lowered,and 3 cases had hypothyroidism.There were 29 cases taking thyroid tablets without hypothyroidism.Conclusion The change of TPOAb level can be observed during the treatment for hyperthyroidism and t hyroid gland tumor.The elevated TPOAb level often predicts the decreased thyroid function.The patients with positive TPOAb should be carefully followed,and for hyperthyroidism patients the treatment should be taken with care.
