Association between Hashimoto's thyroiditis and cholelithiasis: a retrospective cohort study in Taiwan.

ABSTRACT:

Objective

To investigate the relation of Hashimoto's thyroiditis (HT) to cholelithiasis and cholecystectomy in a retrospective population-based study.

Setting

Cohort study.

Participants

We identified 1268 patients aged ?20 years with HT between 2000 and 2010 as the study cohort.

Primary and secondary outcome measures

Patients without HT were randomly selected from a database and propensity-matched with the study cohort at a 1:4 ratio according to age, sex, comorbidities and year of the index date to measure the incidence of cholelithiasis and cholecystectomy.

Results

The cumulative incidence of cholelithiasis was higher in the HT cohort than that in the non-HT cohort (log-rank test, p<0.001), with a 1.91-fold higher risk of choleithiasis (95% CI 1.58 to 2.33) after adjustment for comorbidities. The age-specific relative risk of cholelithiasis in the HT cohort was higher than that in the non-HT cohort for patients aged ?50 years (adjusted HR (aHR)=2.59, 95%?CI 1.33 to 5.03). The sex-specific relative risk of cholelithiasis in the HT cohort was higher than that in the non-HT cohort for women (aHR=1.99, 95%?CI 1.63 to 2.44). Compared with those in the non-HT cohort, patients with HT without (aHR=1.95, 95%?CI 1.53 to 2.49) and with (aHR=1.94, 95%?CI 1.51 to 2.49) thyroxine treatment were associated with a higher risk of cholelithiasis. Compared with those in the non-HT cohort, patients with HT had a higher risk of cholecystectomy (aHR=1.28, 95%?CI 1.02 to 1.61).

Conclusions

Inability to obtain information on several potential confounding factors and misclassification of important covariates are the major limitations of the study. Our study indicates HT per se was associated with the development of cholelithiasis, which has been validated by the association between cholecystectomy and HT. Surveys and health education on cholelithiasis in women aged ?50 years with HT should be considered by clinicians, and further prospective research should be done on this topic.

Project description:BackgroundHashimoto'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.MethodsThe 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.ResultsThe 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.ConclusionThe 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.

Project description:The aim of the present study was to evaluate the association between coexisting lymphocytic thyroiditis (LT) and the clinicopathological features of papillary thyroid carcinoma (PTC). The records of 458 patients with PTC who underwent a total thyroidectomy and lymph node dissection in Sir Run Run Shaw Hospital (Hangzhou, China) were analyzed. In accordance with the histopathology of thyroid parenchyma, the cases were divided into three groups, including Hashimoto's thyroiditis (HT), non-Hashimoto's type LT (NHLT) and no LT. Based on the histopathology, data on age, sex, maximum diameter of tumor, multifocality, extrathyroidal extension, metastatic lymph node size, extranodal extension and tumor grades in the different groups were analyzed and compared. The prevalence of coexisting LT was 29.0% (133/458), of which 7.6% (35/458) was HT and 21.4% (98/458) was NHLT. PTC concomitant with LT was significantly associated with female patients (95.5 vs. 70.2%; P<0.001), a lower rate of extrathyroidal extension and/or capsular invasion (25.6 vs. 39.7%; P=0.004), central lymph node metastasis (CLNM) ratio (10.71 vs. 17.37; P=0.014), higher number of dissected central lymph nodes (16.83 vs. 11.7; P<0.001), larger metastatic lymph nodes (0.66 vs. 0.46 cm; P<0.001), higher occurrence of multifocality (61.7 vs. 50.5%; P=0.029) and earlier pT stage (57.9 vs. 38.8%; P<0.001), regardless of the combined or separate consideration of HT and NHLT. Besides, LT was associated with multifocality [odds ratio (OR), 1.578; 95% confidence interval (CI), 1.046-2.382; P=0.030]. Furthermore, in patients with PTC, CLNM had a significant association with the male sex (OR, 2.000; 95% CI, 1.216-3.288; P=0.006), an age of <45 years (OR, 0.592; 95% CI, 0.398-0.879; P=0.009) and a tumor size of >1 cm (OR, 3.913; 95% CI, 2.431-5.734; P<0.001). In conclusion, patients with PTC and LT showed a greater female preponderance, multifocality, a lower extrathyroidal extension and a lower CLNM ratio. LT was associated with an increased risk of multifocality in PTC.
