Hashimoto's thyroiditis is a chronic autoimmune thyroid disease in which the body's immune system attacks its own cells and tissues, causing inflammation and dysfunction of the thyroid gland. This condition is often accompanied by hypothyroidism, a decrease in thyroid hormone levels. The disease was first described by the Japanese physician Hashimoto in 1912 and has since become the subject of extensive study. Hashimoto's thyroiditis is 5-10 times more common among women than among men and is usually diagnosed between the ages of 30 and 50. The causes of the disease are not fully understood, but it is believed that a combination of genetic and environmental factors play a key role in its development.
History of the disease and interesting historical facts
Hashimoto's thyroiditis was first documented in the scientific journal "Archiv für Klinische Medizin" in 1912. Japanese surgeon Hatsuo Hashimoto observed a patient with an enlarged thyroid gland and associated symptoms who committed suicide. He described in detail the morphological changes in the thyroid tissue, which became the basis for subsequent research. Interestingly, the mechanisms of the pathogenesis of the disease have been clarified over the years. In the 1950s, laboratory tests for thyroid peroxidase and thyroglobulin antibodies were used, which was an important step towards understanding the autoimmune nature of this condition. In the 1990s, research into genetic aspects further expanded our knowledge of the predisposition to Hashimoto's thyroiditis.
Epidemiology
According to epidemiological studies, Hashimoto's thyroiditis occurs in approximately 1-2% of the general population, but among women, this figure can reach 5-10%. The disease is observed in all regions of the world, but its incidence is higher in areas with iodine deficiency. The risk group includes women aged 30 to 60 years, but cases of the disease can also occur in children. The frequency of diagnosis of Hashimoto's thyroiditis increases with age, and this is especially true for the elderly.
Genetic predisposition to this disease
There are various studies that highlight a genetic predisposition to Hashimoto's thyroiditis. Genetic factors include various polymorphisms in genes such as PTPN22, CTLA4, and HLA-DR. Changes in these genes can affect the functioning of the immune system, which increases the risk of developing autoimmune diseases. In addition, close relatives of patients with Hashimoto's thyroiditis have an increased incidence of the disease, which confirms the connection between genetic factors and the development of this pathology.
Risk factors for the development of this disease
There are several risk factors that contribute to the development of Hashimoto's thyroiditis:
- Gender: Female gender significantly increases the risk of the disease.
- Age: Most common in people over 30 years of age.
- Genetic predisposition: having relatives with autoimmune diseases.
- Environmental factors: high levels of radiation and exposure to certain chemicals.
- Infectious diseases: Some viral infections can trigger an immune response that leads to thyroiditis.
- Iodine deficiency: Low iodine intake may contribute to the development of the disease.
- Taking certain medications: Some drugs, such as interferons, can cause problems with the immune system.
Diagnosis of this disease
Diagnosis of Hashimoto's thyroiditis is based on clinical symptoms and various laboratory tests:
- The main symptoms are fatigue, depression, enlarged thyroid gland, weight gain, dry skin, muscle pain and constipation.
- Laboratory tests: determination of the level of TSH, free T4, antibodies to thyroid peroxidase and thyroglobulin.
- Radiological examinations: ultrasound examination of the thyroid gland helps to assess its size and structure.
- Other diagnostic tests: Sometimes a biopsy may be needed to rule out other diseases.
- Differential diagnosis: It is necessary to exclude other causes of hypothyroidism, such as Basedow disease, post-radiation thyroiditis and drug-induced hypothyroidism.
Treatment
Treatment for Hashimoto's thyroiditis includes several methods that are aimed at normalizing thyroid hormone levels and relieving symptoms:
- General treatment: includes regular examinations and monitoring of thyroid function.
- Pharmacological treatment: Replacement therapy with levothyroxine is used to compensate for the hormone deficiency.
- Surgical treatment: indicated in rare cases where there is airway compression or cancer is suspected.
- Other treatments: Recommendations for dietary changes may help improve the patient's overall condition.
List of medications used to treat this disease
The most commonly used medications are:
- Levothyroxine sodium (Eutirox, L-thyroxine)
- Potassium iodide (as adjunctive therapy)
- Immunosuppressants (in severe forms of the disease)
Disease monitoring
Monitoring for Hashimoto's thyroiditis includes the following steps:
- Regular measurement of TSH and free T4 levels.
- Assessment of clinical symptoms and patient's condition.
- Prognosis: With adequate replacement therapy, the disease can be effectively controlled.
- Complications: In some cases, complications such as myxedema may occur.
Age-related features of the disease
Hashimoto's thyroiditis can present differently depending on age group:
- Children and adolescents: They may have problems with growth and development.
- Young people: Symptoms of hypothyroidism may include unexplained fatigue and depression.
- Older adults: May experience more severe symptoms, including cardiovascular problems.
Questions and Answers
- What is Hashimoto's thyroiditis? It is a chronic autoimmune disease of the thyroid gland, characterized by its inflammation and decreased function.
- How is Hashimoto's thyroiditis diagnosed? Diagnostics include laboratory tests for thyroid hormone levels and antibodies to them, as well as ultrasound.
- What is the treatment for Hashimoto's thyroiditis? The main method is thyroid hormone replacement therapy.
- What are the symptoms of Hashimoto's thyroiditis? Major symptoms include fatigue, enlarged thyroid gland, weight gain, depression and hidden metabolic disturbances.
- Can Hashimoto's Thyroiditis Be Avoided? It is impossible to completely eliminate the risk, but maintaining a healthy lifestyle and monitoring your health can reduce the likelihood of developing the disease.
Advice from Dr. Oleg Korzhikov
Dr. Oleg Korzhikov recommends the following for patients with Hashimoto's thyroiditis:
— Undergo regular check-ups: following the test schedule allows you to identify deviations in time and adjust treatment.
— Proper nutrition: it is necessary to increase the consumption of foods rich in iodine and selenium, such as fish, seafood and nuts.
- Physical activity: moderate exercise helps improve overall health.
— Consult a doctor if you experience any changes in your health: any changes in your health require attention and, possibly, treatment adjustments.
Despite the complexity of treatment, with the right approach, patients can lead a full life, taking control of their health.
