Association between affective temperaments and psychosomatic symptoms in women with Hashimoto's thyroiditis.

BACKGROUND: Hashimoto's thyroiditis (HT) is a prevalent autoimmune disease of thyroid gland with a shared immunological mechanism with mood disorders. Affective temperament (AT) is a biologically determined personality trait that has been linked to mood disorders. The aim of this study was to examine the association between dominant AT and levels of psychosomatic symptoms in women newly diagnosed with HT in comparison to clinically healthy subjects. METHODS: The observational cross-sectional study with nested case control study was involving 146 consecutive participants, who were divided into three groups. The two study groups consisted of women with HT (73), including 49 with hypothyroid HT and 24 with euthyroid HT, and the third group was a control group of healthy participants (73). The Serbian version of the TEMPS-A was utilized to assess AT, while the 4DSQ was used to measure psychosomatic symptoms. RESULTS: The results showed that hyperthymic AT was dominant in all examined groups. The groups with HT differed from the control group in terms of depressive and cyclothymic AT. Furthermore, the study found higher levels of psychosomatic symptoms in the group with HT compared to the control group, with significant differences in distress (p = 0.005) and somatization (p = 0.023) levels. All AT was associated with levels of psychosomatic symptoms in subjects with hypothyroid HT. In contrast, in subjects with euthyroid HT, the association was only found between depressive and cyclothymic AT with distress and depression levels, as well as between somatization and cyclothymic AT. No association was found between AT and anxiety levels in subjects with euthyroid HT. CONCLUSION: The research found differences between study groups in the association between AT and levels of psychosomatic symptoms. Further research with a larger sample size is necessary to more clearly define the associations between affective temperaments and psychosomatic symptoms in women with euthyroid and hypothyroid HT.

Influence of Thyroid Disorders upon the Incidence and the Severity of Psychosomatic Symptoms in Patients.

Background: Thyroid disorders are an area of public health concern worldwide. The study aimed to examine the incidence and severity of psychosomatic symptoms (distress, depression, anxiety and somatization) in patients with hypothyroidism, hyperthyroidism, Graves' disease and Hashimoto thyroiditis in relation to clinically healthy subjects. Methods: This case control study was carried out from Feb to Jul 2019 in Serbia. Total sample consisted of 335 subjects, of both sex. The examined group included patients with thyroid disorders treated at the Special hospital for thyroid gland and metabolism disease. Control group included clinically healthy subjects. The Four Dimensional Symptom Questionnaire a self-assessment questionnaire for psychosomatic symptoms was the measuring instrument. Groups were compared using parametric (t-test) and nonparametric (Pearson chi-square test, Mann-Whitney U test, Kruskal-Wallis test) tests. Results: The incidence of all psychosomatic symptoms was high in patients with thyroid disease. Distress was found in 59.8% of the patients in the examined group comparing to the control group (12.8±8.2 vs. 8.9±8.1). The score of depression was twice higher in the examined group (2.05±2.99 vs. 1.23±2.47). Anxiety was present in 46.2% patients in the examined group, while somatization was found in 69.7% subjects. In hypothyroidism there was no difference between the examined and the control group regarding the level of anxiety, likewise with the level of depression in the control group and subjects with Graves' disease and Hashimoto thyroiditis. Conclusion: Psychosomatic symptoms were significantly more severe in patients with thyroid disorders compared to the control group.
