| Summary: | Background and Objectives: Hashimoto's thyroiditis is a chronic inflammation and an autoimmune disease of the thyroid gland that causes hypothyroidism. Genetic, internal, and environmental factors are the causes of this disease. Because human herpes viruses such as herpesvirus type 6 (HHV-6) are involved in some autoimmune disorders, they may also play a role in causing this disease. This study aimed to evaluate the association between human herpes virus 6 (HHV-6) with Hashimoto's thyroiditis.
Materials and Methods: In the present study, 64 samples of thyroid paraffin tissue including 32 samples of thyroid paraffin tissue of healthy individuals as control, and 32 samples of thyroid paraffin tissue of Hashimoto's thyroiditis patients were taken from the pathology department of Loghman Hakim Hospital in Tehran. A questionnaire collected demographic information of patients. After DNA extraction from the samples, the nested-PCR technique was performed using specific primers for HHV-6.
Results: Totally, the HHV6-DNA was found in 34.4% of thyroid tissues of healthy individuals (81.8% female and 18.2% male) and 46.9% of patients with Hashimoto's thyroiditis (73.3% female and 26.7% male). It was found that this difference in virus frequency between the two groups was not statistically significant (P value=0.309). There was also no statistically significant relationship between the prevalence of human herpesvirus type 6 and age or sex.
Conclusion: Based on the present study, the number of HHV-6-infected individuals in Hashimoto's patients and controls did not differ significantly; therefore, HHV-6 appears not to be associated with Hashimoto's thyroiditis.
