Objective: The study aimed to assess antithyroid antibodies in patients with benign thyroid masses and the effect of total thyroidectomy on the antibodies titers.
Patients and Methods: This is a retrospective work of 112 cases managed with total thyroidectomy who have positive antithyroid peroxidase antibodies (TPO-Ab), antithyroglobulin antibodies (Tg-Ab), or both. All patients were euthyroid before surgery. Thyroid function tests and thyroid antibodies levels were measured before and 6 and 12 months after surgery.
Results: Histopathological evaluation revealed Hashimoto thyroiditis (47.3%), colloid nodules (22.3%), and lymphocytic thyroiditis (30.4%). All patients were TPO-Ab positive, while 96 patients (85.7%) were Tg-Ab positive before surgery. There was no considerable change in TPO-Ab and Tg-Ab after surgery (p = 0.817, and p=0.560, respectively). Also, there was no significant difference between the three histopathological diagnoses in the levels of TPO-Ab (p = 0.086) or Tg-Ab (p = 0.673).
Conclusion: Antithyroid antibodies are not valuable markers for diagnosis or prognosis of benign thyroid diseases subjected to total thyroidectomy. We do not recommend their use beyond being a supportive evidence of the possibility of autoimmune nature of the disease if other criteria are confirmed.
