Individuals with Down syndrome (DS) present increased risk for thyroid dysfunction, especially hypothyroidism, due in increased expression of the DYRK1A gene. Objective: The aim of this study was to make a morphological functional thyroid assessment in individuals with DS. Materials and Methods: This is a descriptive cross-sectional study, consisting of 29 individuals with DS, with a mean age of 12,3 (0.66 / 36.00) years, 16 women (55.2%) and 13 men (44.8%), with a morphological/functional thyroid assessment being made comprising hormonal dose (Free T4, TSH), antithyroid antibody (TPOAb and TgAb) and ultrasonography of the thyroid. Results: Twenty-three (79.3%) individuals presented normal thyroid function while 6 (20.7%) presented with thyroid dysfunction, 4 with hypothyroidism and 2 with hyperthyroidism. Autoimmune thyroiditis and goiter were present in 27.6% of the individuals. Conclusion: Thyroid function should be assessed periodically in individuals with DS, in view of the high prevalence of thyroid dysfunction, especially autoimmune thyroiditis with consequent hypothyroidism. Key Words: Down Syndrome, thyroid, ultrasonography, thyroid dysfunction.

Objective To investigate the prevalence of nodular goiter and thyroid dysfunction in uremic patients undergoing hemodialysis (HD) and peritoneal dialysis. Design Cross-sectional study. Setting Single dialysis unit and outpatient clinic. Patients The study included 221 patients [143 HD and 78 continuous ambulatory peritoneal dialysis (CAPD) patients] along with 135 consecutively selected outpatients as controls. Main Outcome Measures Ultrasonography was used to detect patients’ thyroid function and nodular goiter. Results Nodular goiter was detected in 54.8% of the uremic patients and in 21.5% of the controls. Uremic patients had higher prevalence of thyroid dysfunction, which included reduced serum concentration of total T3, total T4, and free T4, and increased serum level of TSH. Hypothyroidism was also observed more frequently in uremic patients than in the control group (5.4% vs 0.7%, p < 0.05). Nodular goiter was more frequently found in females than in males (63.5% vs 48%, p < 0.05). Moreover, the prevalence of nodular goiter increased with age (p < 0.02) in uremic patients. Hemodialysis patients had a higher frequency of reduced total T3 level (46.9% vs 29.5%, p < 0.02). However, CAPD patients had lower T4 levels (6.23 ± 1.82μg/dL vs 7.15± 1.99μg/dL, p < 0.05). Conclusion Because of the high incidence of hypothyroidism and nodular goiter in uremic patients, screening of thyroid function and goiter detection with ultrasound should be considered in evaluation of end-stage renal disease patients.

Anti-thyroid peroxidase antibody (TPO-Ab) is revealed to be inversely associated with thyroid cysts among euthyroid population. TPO-Ab causes autoimmune thyroiditis by bolstering thyroid inflammation. Therefore, at least partly, absence of thyroid cysts could indicate latent thyroid damage. Since participants with subclinical hypothyroidism are reported to have higher HbA1c than normal healthy controls, HbA1c could be inversely associated with thyroid cysts through a mechanism reflecting latent thyroid damage. To investigate the association between HbA1c and thyroid cysts among a euthyroid population, a cross-sectional study was conducted on 1,724 Japanese individuals who were within the normal range of thyroid function [i.e., normal range of free triiodothyronine (T3) and free thyroxine (T4)] and aged 40–74 years. Among this study population, 564 were diagnosed with thyroid cysts. Independently of thyroid related hormones [thyroid stimulating hormone (TSH), free T3, and free T4] and known cardiovascular risk factors, HbA1c was found to be significantly inversely associated with the presence of thyroid cysts. This association remained significant even after this analysis was limited to participants within a normal range of TSH. The fully adjusted odds ratios (ORs) of thyroid cysts for 1 standard deviation (SD) increment of HbA1c were 0.84 (0.74, 0.95) for total participants and 0.80 (0.70, 0.92) for participants within a normal range of TSH. Among participants with normal thyroid function, HbA1c was inversely associated with the presence of thyroid cysts. The absence of thyroid cysts and higher levels of HbA1c could indicate the latent functional damage of the thyroid.

Background: Metabolic syndrome is characterized by hypertension, dyslipidemia, central obesity, glucose intolerance, insulin resistance. Thyroid hormone acts as general pacemaker, accelerating metabolic process and may be associated with metabolic syndrome. There is no information available in literature regarding the prevalence and association of thyroid dysfunction in metabolic syndrome in this central region of the country. Aims and Objective: To estimate the prevalence of thyroid dysfunction in patients of metabolic syndrome. Materials and Methods: It is a duration based prospective cross sectional study including 200 patients of metabolic syndrome. A detailed history, clinical examination and relevant investigations including serum Free T4 (FT4), Free T3 (FT3), Thyroid Stimulating Hormone (TSH) were done. Range, frequencies, percentage, mean, standard deviation and P value were calculated. P value of < 0.05 was taken as significant. Results: Prevalence of thyroid dysfunction in metabolic syndrome patients was 28.5%. Prevalence of subclinical and overt hypothyroidism was 18.5% and 8.5% respectively. In patients with both metabolic syndrome and thyroid dysfunction, most common components associated are diabetes mellitus and hypertriglyceridemia. Conclusion: Thyroid dysfunction is significantly common in metabolic syndrome patients. It should be aggressively detected and treated in these patients for better outcome.

Background: Thyroid dysfunction specially hypothyroidism may occur in type 2 diabetic patients. Objective: To observe thyroid function status in type 2 diabetic patients Materials and Methods: This cross sectional study was carried out in the Department of Physiology, Sir Salimullah Medical College, Dhaka from July 2016 to June 2017. Total 60 subjects including male and female, age ranged from 40 to 60 years were included in this study, among them 30 were non-diabetic subjects and 30 were type 2 diabetic patients. Results: In this study, mean serum TSH level was significantly (p<0.001) higher and serum FT4 level was significantly (p<0.01) lower in diabetic patients than that of apparently healthy non-diabetic subjects. Serum FT3 level was lower in type 2 diabetic patients in comparison to that of non-diabetic subjects but the difference was not statistically significant. However, among the diabetic patients 10% were subclinical hypothyroid and 6.67% were hypothyroid Conclusion: The present study reveals that hypothyroidism occurs in type 2 diabetic patients. So type 2 diabetic patients should measure thyroid hormone levels routinely to detect thyroid dysfunction. KYAMC Journal Vol. 10, No.-2, July 2019, Page 95-98

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.

CONTEXT AND OBJECTIVE: Subclinical thyroid dysfunction is very common in clinical practice and there is some evidence that it may be associated with cardiovascular disease. The aim here was to evaluate the frequencies of subclinical thyroid disease and risk factors for cardiovascular disease among women at a workplace, and to evaluate the association between subclinical thyroid disease and cardiovascular risk factors among them. DESIGN AND SETTING: Cross-sectional study on 314 women aged 40 years or over who were working at Universidade de São Paulo (USP). METHODS: All the women answered a questionnaire on sociodemographic characteristics and risk factors for cardiovascular disease and the Rose angina questionnaire. Anthropometric variables were measured and blood samples were analyzed for blood glucose, total cholesterol and fractions, high-sensitivity C-reactive protein, thyroid-stimulating hormone (TSH), free thyroxine (free-T4) and anti-thyroperoxidase antibodies (anti-TPO). RESULTS: The frequencies of subclinical hypothyroidism and hyperthyroidism were, respectively, 7.3% and 5.1%. Women with subclinical thyroid disease presented higher levels of anti-TPO than did women with normal thyroid function (P = 0.01). There were no differences in sociodemographic factors and cardiovascular risk factors according to thyroid function status, except for greater sedentarism among the women with subclinical hypothyroidism. Restricting the comparison to women with subclinical hypothyroidism (TSH > 10 mIU/l) did not change the results. CONCLUSION: In this sample of women, there was no association between poor profile of cardiovascular risk factors and presence of subclinical thyroid disease that would justify screening at the workplace.

Alterations in thyroid function may contribute to the development of liver fibrosis especially in subjects with non-alcoholic fatty liver disease. This study aimed to investigate the risk of liver fibrosis according to low-normal thyroid function in the general population. We performed a descriptive cross-sectional study in subjects from 18–75 years randomly selected from 16 primary health care centers from 2017–2019. Each subject underwent clinical evaluation, physical examination, blood analysis and transient hepatic elastography. Descriptive and multivariate logistic regression analyses were used to identify factors associated with fibrosis. We included 1096 subjects (60 ± 11 years; 61% women); 70% had strict-normal thyroid function and 30% had low-normal thyroid function. Low-normal thyroid function was associated with a higher liver stiffness (LS) values: 5.2 vs. 4.8 kPa (p = 0.001) and a greater prevalence of fibrosis: 6.1 vs. 3% (p = 0.016) and 4.3 vs. 2.1% (p = 0.044) for the cut-off points of ≥8.0 kPa and ≥9.2 kPa, respectively. After adjustment for potential confounding factors, the risk of fibrosis in subjects with low-normal thyroid function was OR 1.54 (p = 0.213). In conclusion, low-normal thyroid function is associated with higher LS values and a greater risk of liver fibrosis in the general population, being dependent on other metabolic factors.

Abstract Background: Incidental thyroid nodules has become more prevalent in recent years due to applying diagnostic imaging tests. Many studies show that the rate of thyroid cancer in this group of patients is relatively high. Objective: To assess patients with incidentally detected thyroid nodules, including those who were diagnosed with thyroid cancer. Materials and Methods: A cross-sectional study, which involved 208 patients with 389 thyroid nodules detected by thyroid ultrasound. All patients have thyroid function tests. 272 nodules were performed fine-needle aspiration. Patients with thyroid cancer were assessed histopathology after removal. Results: The participants’ mean age was 47.22 ± 12.02. The female / male ratio is 6.7/1. No patients had history of head and neck irradiation or living in epidemiological areas with high prevalence of goiter. TSH level: 96.2% normal, 2.4% low, 1.4% high. In thyroid cancer group: 100% of patients had normal thyroid function. Nodule characteristics on ultrasound: Majority of thyroid nodules had diameters less than 1.5 cm (85.6%), multi-nodularity(52.9%). The largest carcinoma nodule was 2.35 cm, 22.2% of patients with thyroid cancer had ≥ 3 nodules. The malignancy rate of TIRADS 5 was 70.6%. FNA results of 272 thyroid nodules: the majority were Bethesda II (74,2%); the incidence of carcinoma (Bethesda V, VI) is 17.4%. 36 patients account for 17,3%, with 42 nodules were performed surgery, the results of histopathology were 100% of papillary thyroid carcinoma, which was consistent with cytological results. Conclusion: Thyroid nodules are common in women patients at the age of 31-60 with normal thyroid function. Most of them are &lt;1.5 cm in size. There are 17.3% of patients were thyroid carcinoma.

Introduction: Thyroid dysfunction prevalence is high in females worldwide which increases with age. Postmenopausal and elderly women are particularly at risk of developing comorbidities and mortality related to thyroid dysfunction. We aimed to study the prevalence of thyroid dysfunction in postmenopausal women in the National Reference Laboratory of Nepal. Methods: A descriptive cross-sectional study was conducted in National Reference Laboratory from January 2019 to June 2019 including postmenopausal females, ≥49 years. The database of thyroid function test result was used for statistical analysis and proportion of thyroid dysfunction was calculated. The data was collected after approval from the institutional review committee. Statistical Package for Social Sciences version 21 was used to study descriptive data. Results: Out of a total of 160 postmenopausal females with thyroid function tests, 71 (44.4%) had thyroid dysfunction. Subclinical hypothyroidism was the frequently occurring thyroid dysfunction 51 (32%) followed by subclinical hyperthyroidism 13 (8%), hypothyroidism 3 (2%) and hyperthyroidism 3 (2%). In our study population, thyroid dysfunction peaked at 49 to 58 years of age interval 53 (33.1%) and subclinical hypothyroidism was the most frequent form 38 (23.7%). Conclusions: Subclinical hypothyroidism was the common thyroid dysfunction in postmenopausal age which peaked at 49 to 58 years of age group. Early postmenopausal females are predisposed to increased risk of comorbidities (cardiovascular disease, osteoporosis with high fracture, depression) which could be exacerbated with thyroid dysfunction; therefore awareness of thyroid dysfunction prevalence and thyroid screening for early management seems appropriate in Nepalese postmenopausal women.

Thyroid function has a close link with inflammation. However, it is still unknown whether the dietary inflammatory potential is associated with thyroid function. We aimed to assess the relationship among them using the data from the National Health and Nutrition Examination Survey (NHANES). This study was a cross-sectional study, where weighted multivariable linear regression, subgroup analyses, and interaction terms were employed. Thyroid function was assessed by eight indexes, including total and free T4 and T3, Tg, TgAb, TPOAb, and TSH. A total of 2346 male participants aged ≥20 years with an average age of 50.74 ± 17.68 years were enrolled. The mean DII score among participants was −0.46 ± 1.73, ranging from −4.12 to 4.41, and mean total thyroxine (T4) was 7.61 ± 1.51 μg/dL. We found a positive association between DII and total T4 (β = 0.07; p = 0.0044). Using subgroup analysis, this association became stronger in both the iodine-deficient and obese group (iodine-deficient group: β = 0.15, p < 0.0001; obese group: β = 0.14, p < 0.0001). In conclusion, men adhering to a more pro-inflammatory diet appeared to have higher total T4 levels. However, these hormone variations were still within the normal clinical range and more well-designed studies are still needed to validate the causal relationship between DII and thyroid function.
