The aim of the present study was to determine associations of thyroid hormone levels and different metabolic parameters and anthropometric measurements with volume of nodular and nonnodular thyroid as well as with prevalence of goiter and thyroid nodules in middle-aged euthyroid subjects. Methods. The study consisted of 317 euthyroid subjects aged 48-49 from the Kaunas Cardiovascular Risk Cohort study. Thyroid-stimulating hormone (TSH), free thyroxine (FT4), and antithyroid peroxidase antibody (ATPO) levels, as well as anthropometric and metabolic parameters and smoking information, were evaluated. Results. In subjects with and without thyroid nodules, thyroid volume correlated with components of metabolic syndrome, body mass index (BMI), smoking, and TSH levels. In the nonnodular thyroid group, thyroid volume was also positively related to serum insulin and HOMA-IR, whereas a negative correlation between thyroid volume and leptin was identified in the nodular thyroid group. The goiter was identified in 12.3% of subjects. Female gender, thyroid nodules, smoking, BMI, and levels of TSH were independent predictors for goiter. Thyroid nodules were found in 31.2% of participants. Female gender, higher TSH levels, and thyroid volume were independent risk factors for thyroid nodules. Conclusions. Female gender, thyroid nodules, smoking, BMI, and TSH levels were identified as potential predictors of goiter. Female gender, TSH levels, and thyroid volume predicted the presence of thyroid nodules.

Abstract Purpose: In our study, we aimed to determine the frequency of thyroid nodules in patients with acromegaly according to the American College of Radiology (ACR) Thyroid Imaging, Reporting and Data System (TI-RADS) classification and its relationship with acromegaly disease activity. Methods: A total of 56 patients with acromegaly and age, sex, and body mass index matched with 56 healthy control subjects were included in our study. Thyroid-stimulating hormone, free thyroxine, and anti-thyroperoxidase antibody levels of patients and control subjects were measured. In addition, patients and healthy controls were evaluated by ultrasonography to determine thyroid structure, thyroid volume, and thyroid nodules and to make ACR TI-RADS classification. Results: Thyroid nodules were present in 31 (55.4%) of 56 patients in the acromegaly group and 20 (35.7%) of 56 subjects in the control group, and the frequency of thyroid nodules was significantly higher in the acromegaly group (p=0.038). The mean number of nodules in the acromegaly group and control group was 1.27±1.43 and 0.48±0.73, respectively, and the mean number of nodules was significantly higher in the acromegaly group (p=0.003). The number of patients with TI-RADS 1, TI-RADS 2, and TI-RADS 4 nodules in the acromegaly group was higher than the control group (p=0.026, p=0.049, p=0.007, respectively). No difference was found in terms of cytological findings between those who have undergone FNAB in the acromegaly group and control group. Conclusion: In our study, we found that the frequency of thyroid nodules, the number of thyroid nodules, and the number of TI-RADS 1, TI-RADS 2, and TI-RADS 4 nodules increased in patients with acromegaly. There was no significant difference between acromegaly disease activity and thyroid nodule frequency, number of thyroid nodules, and TI-RADS classifications.

Abstract Objective. To explore the prevalence and its associated metabolic factors of thyroid nodules (TNs) among subjects who participated in the physical examinations in Chongqing, China. Methods. The participants from the Health Management Center of JinShan Hospital of Chongqing Medical University, between September 2015 and May 2020, were included in this study. All of the participants underwent thyroid ultrasonography, anthropometric measurements, and serum examinations. Differences in the TNs prevalence were compared with the chi-square test or Wilcoxon rang-sum test. Multivariable logistic regression analyses were used to estimate the metabolic factors associated with TNs and multi thyroid nodules (MTNs). Results. Of the included 121702 participants, 41547 had TNs, and 20899 had MTNs, with the prevalence of 34.1% and 17.0%, respectively. Women had a significantly higher prevalence of TNs than men (40.6% vs. 29.8%; χ2 = 1517.33, P < 0.001), and TNs prevalence was gradually increased with age (P for trend < 0.001). Female gender, advanced age, and metabolic factors including central obesity, BMI,hypertension, diabetes and fatty liver were positively associated with TNs; hyperlipoidemia and hyperuricemia were not independent risk factors of TNs. While female gender, advanced age, central obesity, hypertension and diabetes were independent risk factors of MTNs. Conclusions. The prevalence of thyroid nodules was relatively high. The associated factors identified in this study could help the clinicians to detect the high-risk patients and make targeted screening strategies for the preventing of the occurrence of TNs.

Background: In India, thyroid cancer accounts for less than 1% of all malignancies (2% of women and 0.5% of men). Thyroid cancer is responsible for 6 deaths per 1 million persons annually. Serum TSH is a well-established growth factor for thyroid nodules, however its role in thyroid malignancy is inconclusive hence this study was conducted with the objective to determine the association between serum Thyroid stimulating hormone (TSH) concentrations with thyroid carcinoma.Methods: Case control study was conducted in a tertiary care centre. 120 Benign and malignant thyroid subjects respectively were included in the study. Newly diagnosed and record based data collection was done. Measurements of serum TSH concentrations were performed by automated immune chemiluminescent assay. Data was analyzed using SPSS 22 version software, Chi-square test was used as test of significance for qualitative data, p value of <0.05 was considered as statistically significant.Results: Majority of them were females in the age group 26 to 40 years in both the groups and were diagnosed to have solitary thyroid nodule. In malignant thyroid nodules 51.7% were diagnosed to have follicular carcinoma, 46.7% had papillary carcinoma and 1.7% were diagnosed to have Hurthle cell carcinoma. Significant association was observed between TSH levels and diagnosis of thyroid lesions. TSH was raised (>4mIU/L) in 46.6% of malignant nodules and in 15% of benign nodules. Raised TSH had an odds ratio of 4.958 for Thyroid malignancy compared to benign nodulesConclusions: Higher TSH levels were associated with Thyroid malignancy and the risk of malignancy rises in parallel with serum TSH within normal range, and high levels of serum TSH concentrations was associated with advanced stage of thyroid cancer.

Background. A recent study has reported that high circulating 25-hydroxyvitamin D [25(OH)D] is associated with low circulating thyroid-stimulating hormone (TSH) levels, but only in younger individuals. The goal of the present study was to explore the relationship between vitamin D status and circulating TSH levels with thyroid autoimmunity and thyroid hormone levels taken into consideration in a population-based health survey of middle-aged and elderly individuals.Methods. A total of 1,424 Chinese adults, aged 41–78 years, were enrolled in this cross-sectional study. Serum levels of 25(OH)D, TSH, thyroid hormones, and thyroid autoantibodies were measured.Results. The prevalence of vitamin D insufficiency was 94.29% in males and 97.22% in females, and the prevalence of vitamin D deficiency was 55.61% in males and 69.64% in females. Vitamin D status was not associated with positive thyroid autoantibodies after controlling for age, gender, body mass index, and smoking status. Higher 25(OH)D levels were associated with lower TSH levels after controlling for age, FT4 and FT3 levels, thyroid volume, the presence of thyroid nodule(s), and smoking status in males.Conclusion. High vitamin D status in middle-aged and elderly males was associated with low circulating TSH levels independent of thyroid hormone levels.

Tobacco smoking increases the risk of goitre and Graves' disease, but the association with thyroid nodularity and hypothyroidism has not been settled. We investigated 4649 subjects from the general population with questionnaires, thyroid ultrasonography and blood tests. The results were analysed in multivariate regression models. Tobacco smoking was associated with an increased prevalence of thyroid multinodularity (odds ratio (OR) 1.9; 95% confidence interval (CI) 1.4-2.5), but not with increased prevalence of solitary thyroid nodules. The tendency was for a stronger association in the area with the most pronounced iodine deficiency (P for interaction=0.08). Lower levels of serum TSH were found among tobacco smokers (P<0.001), but this association disappeared when adjustment was made for thyroid nodularity and thyroid Volume. The prevalence of elevated TSH levels was markedly reduced among smokers (OR 0.47; 95% CI 0.33-0.67). No association was found between smoking and hyperthyroidism. The observed associations seem to be explainable by the blocking of iodine uptake and organification in the thyroid by thiocyanate, a degradation product of cyanide in tobacco smoke.

Objective: To correlate the size of autonomously functioning thyroid nodules (AFTNs) with thyroid function tests. Methods: A retrospective analysis was performed of data from patients with a diagnosis of a single AFTN who were seen in a university-based endocrinology clinic between January 1, 2003, and December 31, 2015. Patients with a nuclear thyroid scan confirming the presence of an AFTN without significant cystic degeneration were included in the study. Results: The volume of the AFTN and the corresponding thyroid function tests were compared in 32 patients who met inclusion criteria. There was no correlation between the volume of the AFTN and thyroid-stimulating hormone (TSH) levels ( r2 = 0.044). There was also no volume threshold below which an AFTN was always associated with a TSH within the reference range. Conclusion: The results agree with the findings of other recent studies comparing the volume of AFTNs with TSH levels, suggesting that smaller nodules can still demonstrate subclinical and overt hyperthyroidism and that a normal TSH level does not preclude the presence of an AFTN.

AbstractIn euthyroidism, as thyroid Stimulating hormone (TSH) levels increase, the free triiodothyronine (FT3) to free thyroxine (FT4) ratio increases. The aim of this study was to assess if beyond the euthyroid range of TSH levels FT3/FT4 ratio continues to increase and if levothyroxine treatment reduces this ratio, possibly through TSH suppression. This cross sectional retrospective study included a total of 77 832 patients [age 22.76±15.17 years (4 days to 112 years)] evaluated and treated in community clinics between January 2009 and September 2013. Blood samples drawn in community clinics for which TSH, FT4, FT3, age, and gender were available were included. Tests with TSH below 0.5 IU/l were excluded as were samples taken during pregnancy. The FT3/FT4 ratio continued to increase significantly even with TSH above 50 mIU/l (p for trend<0.001) with an increase of more than 50% over the entire TSH range. With increasing age and female gender, the phenomenon was less prominent (p<0.001). Levothyroxine treated patients had significantly lower FT3/FT4 ratios in comparison to untreated patients up to TSH levels of 5.0 mIU/l. In conclusion, increasing TSH increases FT3/FT4 ratio even with severe hypothyroidism, less so with aging. With levothyroxine therapy, a ratio similar to untreated patients is achieved at TSH of above 5.0 mIU/l. Since T3 suppresses TSH better than T4, administration of T3 would likely normalize the FT3/FT4 ratio at a lower, ostensibly more physiological, TSH level. This could be seen as a rationale for add-on T3 therapy.

Thyroid Stimulating Hormone (TSH) levels can be measured accurately down to a very low serum concentration with an immunoassay. When the serum TSH level is in the normal range, measuring the T3 and T4 levels is redundant. The objective of this study is to study the relation of TSH levels postoperatively in thyroid surgeries with the timing for thyroxin treatment as a supplemental and suppressive therapy. A prospective cohort study was done on 84 patients underwent thyroid operations in Al-Yarmouk Teaching Hospital from March 2010 through November 2012. Patients underwent different thyroid operations (lobectomy, subtotal thyroidectomy and total thyroidectomy) for different thyroid pathology. Later, they were followed up by TSH assay in periods of 2, 4, 6 and 12 months postoperatively. Variables were compared by using the analysis of variance, ANOVA test. P – values equal or less than 0.05 and 0.01 were considered to be statistically significant and highly significant, respectively. The mean age of patients was 43.30 ± 10.19 years. The females made the vast majority of study sample (85.7%). Patients were divided into six groups: simple colloid goiters (17 patients), multinodular goiters (32 patients), solitary thyroid nodules (11 patients), Hashimoto’s thyroiditis (8 patients), Graves’ disease (8 patients) and papillary and follicular carcinomas (8 patients). The study revealed that all patients with malignant thyroid nodules (i.e. those with total thyroidectomies) and the vast majority of patients with Hashimoto’s thyroiditis were in definite need for thyroxin treatment post-operatively. Other patients were variable in their need and timing of treatment according to the histopathological results and the type of operations. In conclusion; measurement of TSH level postoperatively is a good indicator for need of thyroxin treatment and for dose adjustment with the help of pathological results and the type of surgery.

In an assessment of risk for differentiated thyroid cancer (DTC) in individuals with human papillary thyroid cancer (PTC) and thyroid nodules a cohort prospective study was undertaken to establish the significance of preoperative thyroid-stimulating hormone (TSH) levels. Confirmed histologically PTC cases in one tertiary care center, and matched healthy individuals were tested for TSH, T3, T4 and T4 free total. The ORs and 95% confidence intervals have been calculated using conditional logistic regression models (CI). The blood TSH levels were related to the higher risk of PTC for men (OR,0,09; 95% Ci, 04–0,21, 95% CI and women) compared with the middle tertile of the TSH levels in the normal range (OR,0,07; 95 percent CI, 0,04–0,1). Over the normal range of TSH levels, an elevated PTC risks were connected amongst women (OR 0,09; 95% CI, 0,04–0,21) but not amongst men (OR,0,07; 95% CI, 0,04–0,1). With an increase in TSH level in the normal range between men and women, the risk for PTC reduced (Ptrend=0.041 and 0.0001). The risk of PTC related to TSH levels has been dramatically elevated above  the normal range for men  and TSH values below the normal range for women.

Background: Thyroid cancer is the most common endocrine malignancy and its incidence continues to rise. Thyroid carcinoma in most cases presents clinically as a solitary nodule or as a dominant nodule within a multinodular thyroid gland. There are a number of well-established of predictors of malignancy in thyroid nodules. More recently studies have suggested that higher concentration of TSH, even within the normal range are associated with subsequent diagnosis of thyroid cancer in patients with thyroid nodules and even higher serum TSH levels have been found associated with advanced stages of thyroid cancer. Objectives were to determine the association between serum thyroid stimulating hormone (TSH) concentration and thyroid cancer and to estimate serum TSH levels in different stages of thyroid malignancy.Methods: A hospital based observational study was conducted in a tertiary care hospital for a period of 2 year. 120 patients presenting with thyroid nodule without an overt thyroid dysfunction during the study period were included in the study. Chi-square was used as test of significance. Independent t test was the test of significance for quantitative data between two groups.Results: In the study majority of thyroid cancer patients (106 out of 120) had serum TSH concentrations ranging 1.71mIU/L-5.5mIU/L i.e. within normal range but towards higher range. Mean serum TSH concentrations was significantly high in advanced stages of carcinoma. Mean Serum TSH was high in Stage III and Stage IV (5.17±1.36mIU/l) compared to stage I and II (4.03±1.87mIU/l).Conclusions: The study concludes that TSH levels were in the Upper reference range in majority of thyroid malignancies and high levels of serum TSH concentrations associated with advanced stage of thyroid cancer.
