BACKGROUND: Smoking has been associated with Graves' disease, but it remains unclear if the association is present in other thyroid disorders. OUTCOME VARIABLES: Graves' disease, Graves' ophthalmopathy, toxic nodular goitre, non-toxic goitre, post-partum thyroid disease, Hashimoto's thyroiditis, or hypothyroidism. MATERIAL AND METHODS: A search of MEDLINE identified 25 studies on the association between smoking and thyroid diseases. RESULTS: In Graves' disease eight studies were available showing an odds ratio (OR) of 3.30 (95% confidence interval (CI): 2.09-5.22) in current smokers compared with never smokers. In ex-smokers there was no significant excess risk of Graves' disease (OR=1.41, 95% CI: 0.77-2.58). The OR associated with ever smoking in Graves' ophthalmopathy (4.40, 95% CI: 2.88-6.73, six studies) was significantly higher than in Graves' disease (1.90, 95% CI: 1.42-2.55, two-sided P-value <0.01). Ever smoking was not associated with toxic nodular goitre (OR=1.27, 95% CI: 0.69-2.33, three studies), while there was an increased risk of non-toxic goitre in smokers if men were excluded (OR=1.29, 95% CI: 1.01-1.65, eight studies). The risk associated with smoking was significantly lower in men than in women for both Graves' disease and non-toxic goitre. Hashimoto's thyroiditis and post-partum thyroid dysfunction were also associated with smoking while the association with hypothyroidism did not reach statistical significance. CONCLUSIONS: Cessation of smoking seems associated with a lower risk of Graves' disease than current smoking. Smoking increases the risk of Graves' ophthalmopathy beyond the risk associated with Graves' disease alone. Smoking cessation may lead to a decrease in morbidity from Graves' disease, especially in women.

The objective of this study was to investigate whether IRF7 polymorphisms are associated with autoimmune thyroid diseases (AITDs). We selected three single nucleotide polymorphisms (SNPs) of IRF7, namely, rs1061501, rs1131665, and rs1061502 for genotyping using PCR-based ligase detection reaction (LDR) method in a total of 1659 participants (592 with Graves’ disease, 297 with Hashimoto’s thyroiditis, and 770 healthy controls). Gene-disease and genotype-clinical phenotype associations were evaluated for the three SNPs. Our results showed that the AG genotype and the minor allele G frequency of rs1131665 and rs1061502 in AITD patients were both higher than those of the controls (rs1131665: AG genotype: P=0.017, OR=1.968; allele G: P=0.018, OR=1.946; rs1061502: AG genotype: P=0.029, OR=1.866; allele G: P=0.031, OR=1.847). Subgroup analysis also showed that the AG genotype and the minor allele G frequency of rs1131665 and rs1061502 in Graves’ disease patients were both higher than those of the controls (rs1131665: AG genotype: P=0.015, OR=2.074; allele G: P=0.016, OR=2.048; rs1061502: AG genotype: P=0.034, OR=1.919; allele G: P=0.035, OR=1.898). Furthermore, the allele G frequency of rs1061501 was associated with Graves’ ophthalmopathy (P=0.035, OR=1.396). No significant difference in IRF7 polymorphisms was found between Hashimoto’s thyroiditis patients and controls. Our study has revealed for the first time that IRF7 is a susceptibility gene for AITD, especially for Graves’ disease and Graves’ ophthalmopathy.

AbstractThe risk of thyroid autoimmunity and thyroid dysfunction among patients with gout and hyperuricemia has not been well defined. This study was undertaken to examine the impact of gout and hyperuricemia on risk of thyroid disorders including thyroid autoimmunity and thyroid dysfunction. A population-based cross-sectional study was conducted to assess the risk of thyroid autoimmunity and thyroid dysfunction related to gout and hyperuricemia, which included 115 gout patients, 439 hyperuricemic patients, and 2 254 individuals without gout and hyperuricemia. A systematic review and meta-analysis of 14 observational studies was also done to systematically evaluate the risk of thyroid dysfunction among patients with gout and hyperuricemia. Findings from the cross-sectional study suggested a significantly increased risk of hypothyroidism among female gout patients (OR=2.44, 95% CI 1.15–5.17, p=0.02). Besides, gout could also substantially increase risk of Hashimoto’s thyroiditis in women (OR=3.15, 95% CI 1.53–6.49, p=0.002). The meta-analysis proved a considerably increased risk of hypothyroidism among both gout patients (OR=1.51, 95% CI 1.23–1.85, p<0.001) and hyperuricemic patients (OR=1.34, 95% CI 1.11–1.61, p=0.002). Moreover, this meta-analysis also suggested that gout could also significantly increase the risk of hyperthyroidism (OR=1.25, 95% CI 1.06–1.48, p=0.01). The findings from the study suggest increasing risk of hypothyroidism and Hashimoto’s thyroiditis among gout patients. Moreover, gout but not hyperuricemia is linked to increased risk of hyperthyroidism. More studies are warranted to elucidate the influence of gout and hyperuricemia on thyroid disorders.

Current data show an association between thyroid diseases and cognitive dysfunction and depression. Depression may affect the clinical picture and the course of thyroid diseases, while also certain correlations are seen between depression and an increased risk of the incidence of these diseases.The aim of this study was tracing associations among depression and hyperthyroidism in the course of Graves’ disease and toxic nodular goitre in particular stages of the disease and frontal cognitive function.Eighty persons (63 females and 17 males) with diagnosed hyperthyroidism, their age ranging between 18 and 55 years, were qualified into the study, fifty (50) of them with Graves’ disease and thirty (30) with toxic nodular goitre.Following performed hormonal evaluations, patients with overt or subclinical hyperthyroidism were identified, together with patients in euthyroidism.The control group included thirty-one (31) healthy volunteers, matched with the study group, regarding their age, sex and education.In the evaluation of working memory and executive functions, the Wisconsin Card Sorting Test (WCST) was used, while Beck Depression Inventory (BDI) was applied to determine the degree of depression symptoms.The obtained results showed impairment of WCST performance in patients with Graves’ disease and with toxic nodular goitre. Any significant associations between the degree of depression symptoms and the efficiency of either working memory or executive functions were found.Acknowledgements:This research was supported by grant 502-16-683 Medical University of Lodz.

The Relationship

Objective An increase in papillary thyroid carcinoma in patients with Hashimoto's thyroiditis has been described. We have yet to find literature discussing a relationship with micropapillary thyroid carcinoma(MPC). Our objective is (1) to assess the relationship between Papillary Microcarcinoma and Hashimoto's Thyroiditis in thyroids without malignant disease, (2) compare effect of the presence of Hashimoto's on prognostic factors in patients. Methods Pathology reports were reviewed for consecutive patients undergoing total thyroidectomy over a 6-year period from 2002 to 2007. Patients with benign pathologies were included. Patients with MPC and no other malignancy were also included. This lead to a cohort of 314 patients. Statistical significance was calculated using Fisher's exact test and a chi-squared analysis. Results Out of the 314 patients, 98 were positive for Hashimoto's thyroiditis on biopsy of the removed thyroid. 58% of the patients with Hashimoto's thyroiditis had an incidental MPC, as compared to 42% of patients where Hashimoto's was not found. Additionally, in Hashimoto patients, 61% of the MPCs were multifocal versus 43% multifocal in the non-Hashimoto group (p-value <0.05 in each comparison). Bilaterality of MPC was also increased in patients with Hashimoto's (22% vs 39%). Conclusions Patients with Hashimoto's thyroiditis in this study had an incidence of MPC of 58%, which is significantly greater than the 42% in those without. Hashimoto's was also associated with an increased risk of bilaterality and multifocality. Studies are needed to further corroborate these findings.

Summary Aim of this study is to evaluate new and controversially discussed indications for determining the thyroglobulin (Tg) level in different thyroid diseases to support routine diagnostics. Methods: The following groups were included: 250 healthy subjects without goiter, 50 persons with diffuse goiter, 161 patients with multinodular goiter devoid of functional disorder (108 of them underwent surgery, in 17 cases carcinomas were detected), 60 hyperthyroid patients with autonomously functioning nodular goiter, 150 patients with Hashimoto’s thyroiditis and 30 hyperthyroid patients with Graves’ disease. Results: The upper limit of the normal range of the Tg level was calculated as 30 ng Tg/ml. The evaluation of the collective with diffuse goiter showed that the figure of the Tg level can be expected in a similar magnitude as the thyroid volume in milliliters. Nodular tissue led to far higher Tg values then presumed when considering the respective thyroid volume, with a rather high variance. A formula for a rough prediction of the Tg levels in nodular goiters is described. In ten out of 17 cases with thyroid carcinoma, the Tg was lower than estimated with thyroid and nodular volumes, but two patients showed a Tg exceeding 1000 ng/ml. The collective with functional autonomy had a significantly higher average Tg level than a matched euthyroid group being under suppressive levothyroxine substitution. However, due to the high variance of the Tg values, the autonomy could not consistently be predicted with the Tg level in individual cases. The patients with Hashimoto’s thyroiditis showed slightly decreased Tg levels. In Graves’ disease, a significantly higher average Tg level was observed compared with a matched group with diffuse goiter, but 47% of all Tg values were still in the normal range (< 30 ng/ml). Conclusion: Elevated Tg levels indicate a high probability of thyroid diseases, such as malignancy, autonomy or Graves’ disease. However, as low Tg concentrations cannot exclude the respective disorder, a routine Tg determination seems not to be justified in benign thyroid diseases.
