|Hashimoto's Disease||Procedure: Total thyroidectomy performed||Not Applicable|
The study hypothesis is that elimination of anti-TPO antibodies ameliorates the typical Hashimoto symptoms like tiredness,increased need of sleep, pain in musculature and joints and dryness in eyes and mouth. It is necessary that the total thyroidectomy is meticulously performed. We have proven the effect on the antibodies, and we have also proven that the operation procedure can be performed without more complications like recurrent nerve damage and hypocalcemia. Neutrality is secured by randomization done by a neutral institution, laryngoscopy by neutral doctors and instructions filling out the QoL-schemes performed by non-biased study nurses.
The study runs for at least 18 months with controls every 6 months. Blood samples are taken and international approved QoL-schemes are filled in. In addition to the randomised main group a side group of patients fulfilling 2 of the 3 inclusion criteria are followed in parallel in order to elucidate the spontaneous development of the disease and showing critical values of antibodies making the symptoms turn up.

No Intervention: Non-surgical treatment only
Control arm. This arm receives standard medical hormone treatment (Thyroxine substitution) only and no surgical intervention.
Active Comparator: Total thyroidectomy performed
Surgical arm.The approach for total thyroidectomy will be a complete removal of all visible, and immunological active thyroid tissue with a high accuracy, with a special focus on three sites; 1) The angle where the recurrent laryngeal nerve enters the cricothyroid membrane, 2) The pyramidal lobe and 3) The hilus where the superior vessels are entering the field. Standard Thyroxine supplementation maintained as in the control group.
Procedure: Total thyroidectomy performed
Surgery combined with standard thyroxine treatment
- Better outcome in Quality of Life by operation [ Time Frame: 18 months ]The patiens are followed for 18 months with blood samples and filling in Quality of Life schemes every 6 months
- Lowering of antibodies (Blood samples) [ Time Frame: 18 months ]Blood samples every 6 months
- Safety in performing absolute total thyroidectomy (recurrence nerve and long lasting hypocalcemia) [ Time Frame: 12 months ]Safety concerning the recurrence nerve and long lasting hypocalcemia. Interim analysis after 75 patients.
- Interim analysis after 75 patients concerning safety (recurrent nerve control by laryngoscopy and hypocalcemia control by blood samples) [ Time Frame: 12 months ]The patients operated upon are investigated after 12 months concerning safety. The recurrent nerve control by laryngoscopy and hypocalcemia control by blood samples.
