Autoimmune thyroiditis: an update on treatment possibilities

Autoimmune thyroiditis (AIT) is due to an autoimmune process that destroys thyrocytes, leading to hormonal disorders. AIT is more common in women, and the aetiology is multifactorial. The destruction of thyroid cells may release free thyroid hormones into the bloodstream, causing hyperthyroid symptoms. With further destruction of thyroid cells, patients develop euthyroidism and eventually chronic hypothyroidism. The diagnosis of AIT is based on clinical symptoms, positive anti-thyroid antibodies, ultrasound, and histological features. The main goal of treatment is correcting hormonal disorders and achieving euthyroidism. Treatment of AIT involves replacing thyroid hormone deficiency with the use of synthetic hormones. Prophylactic levothyroxine (L-T4) treatment of euthyroid patients with AIT may reduce both serological and cellular markers of autoimmunisation. Attention should be paid to the starting dose of L-T4, potential drug interactions, and drug formulation. A follow-up should be planned to determine the optimal dose. The authors highlighted that a healthy lifestyle and supplementing selected vitamins and microelements appropriately are essential. In selected clinical conditions, thyroidectomy should be considered. There are also alternative therapeutic strategies, such as herbal medicine and acupuncture, but their effectiveness has yet to be conclusively confirmed in research studies. Monitoring the thyroid gland enlargement and the possibility of developing nodular goitre is integral to patient care over AIT patients. In conclusion, treating AIT is complex, involving thyroid hormone replacement therapy, taking care of a healthy diet and lifestyle, and proper supplementation. It requires an individual approach. Regular follow-up is necessary to control the disease and minimise its effects.
