Anti-TPO and anti-Tg antibody levels of the group in which L-thyroxine treatment was started were found to be higher than those in the untreated patients (p = 0.01 and p = 0.051, respectively). L-thyroxine was initiated in 13 (35.1%) of the 37 patients who were initially euthyroid and did not receiving treatment at presentation because of subclinical or clear hypothyroidism was observed of the follow-up.
