Abstract
Background:
Hashimoto disease is a chronic autoimmune thyroiditis. Despite adequate hormone substitution, some patients have persistent symptoms that may be the result of immunologic pathophysiology.

Objective:
To determine whether thyroidectomy improves symptoms in patients with Hashimoto thyroiditis who still have symptoms despite having normal thyroid gland function while receiving medical therapy.

Design:

Randomized trial. (ClinicalTrials.gov: NCT02319538)

Setting:
Secondary care hospital in Norway.

Patients:
150 patients aged 18 to 79 years with persistent Hashimoto-related symptoms despite euthyroid status while receiving hormone replacement therapy and with serum antithyroid peroxidase (anti-TPO) antibody titers greater than 1000 IU/mL.

Intervention:
Total thyroidectomy or medical management with hormone substitution to secure euthyroid status in both groups.

Measurements:
The primary outcome was general health score on the Short Form-36 Health Survey (SF-36) at 18 months.
Secondary outcomes were adverse effects of surgery, the other 7 SF-36 subscores, fatigue questionnaire scores, and serum anti-TPO antibody titers at 6, 12, and 18 months.

Results:
During follow-up, only the surgical group demonstrated improvement:
Mean general health score increased from 38 to 64 points, for a between-group difference of 29 points (95% CI, 22 to 35 points) at 18 months.
Fatigue score decreased from 23 to 14 points, for a between-group difference of 9.3 points (CI, 7.4 to 11.2 points).
Chronic fatigue frequency decreased from 82% to 35%, for a between-group difference of 39 percentage points (CI, 23 to 53 percentage points).
Median serum anti-TPO antibody titers decreased from 2232 to 152 IU/mL, for a between-group difference of 1148 IU/mL (CI, 1080 to 1304 IU/mL).
In multivariable regression analyses, the adjusted treatment effects remained similar to the unadjusted effects.

Limitation:
Results are applicable only to a subgroup of patients with Hashimoto disease, and follow-up was limited to 18 months.

Conclusion:
Total thyroidectomy improved health-related quality of life and fatigue, whereas medical therapy did not.
This improvement, along with concomitant elimination of serum anti-TPO antibodies, may elucidate disease mechanisms.
