Thyroid antibody status, thyroid function, and the risk of coronary heart disease and stroke: An individual participant data analysis from 14 cohorts Ola Hysaj, Orestis Efthimiou, Tinh-Hai Collet, Anne R Cappola, Heba Alwan, Jacobijn Gussekloo, Layal Chaker, Maryam Kavousi, Fereidoun Azizi, Anna Köttgen, Elizabeth Selvin, Stella Trompet, John P Walsh, Suzanne J Brown, Massimo Iacoviello, Robin P F Dullaart, Stephan J L Bakker, José A Sgarbi, Till Ittermann, Henry Völzke, Isabela M Benseñor, Sergio Valdés, Cristina Maldonado-Araque, Bruce M Psaty, Frank J Wolters, Bjørn O Åsvold, Cinzia Del Giovane, Nicolas Rodondi European Journal of Endocrinology, 2025 Objective The association of thyroid peroxidase antibodies (TPOAb) status with cardiovascular disease (CVD) risk, independent of thyroid function, remains unclear. We aimed to determine whether positive TPOAb is associated with increased CVD risk, overall and among individuals with subclinical hypothyroidism. Methods We conducted a 2-stage individual participant data analysis including cohort studies identified through the Thyroid Studies Collaboration and systematic database searches (MEDLINE, EMBASE, Cochrane Library) through November 2024. Primary outcomes were coronary heart disease (CHD) events, CHD mortality, stroke events, and stroke mortality. We used Cox proportional hazards models, adjusted for age, sex, and thyroid-stimulating hormone (TSH) within each cohort, followed by a random-effects meta-analysis to assess cardiovascular outcomes by TPOAb status, overall and in the subclinical hypothyroidism subgroup. Results Among 100 250 adults from 14 cohort studies (median age 55 years, 56.7% women), 11.9% were TPOAb-positive, and 5.4% had subclinical hypothyroidism. In the overall population, we found no evidence of increased CVD risk in TPOAb-positive compared to TPOAb-negative individuals: Hazard ratio (HR) 1.00 (95% CI 0.90-1.11) for CHD events; HR 0.95 (95% CI 0.78-1.16) for CHD mortality; HR 0.98 (95% CI 0.87-1.11) for stroke events; and HR 1.06 (95% CI 0.81-1.40) for stroke mortality. In subclinical hypothyroidism, positive TPOAb was similarly not associated with increased risk for any of the CVD outcomes. Conclusions Positive TPOAb status was not associated with increased risk of CHD or stroke. These findings do not support the use of TPOAb testing for cardiovascular risk assessment in the overall population or among individuals with subclinical hypothyroidism.
The Metabolic Vulnerability Index (MVX) in Subclinical Thyroid Disorders and Euthyroidism: A Cross-Sectional Exploratory Analysis from the ELSA-Brasil Study Carolina Castro Porto Silva Janovsky, Vandrize Meneghini, William Tebar, Joao Roberto Maciel Martins, José Augusto Sgarbi, Patrícia de Fatima dos Santos Teixeira, Itamar de Souza Santos, Steven R. Jones, Michael J. Blaha, Peter P. Toth, Marcio S. Bittencourt, Raul D. Santos, Paulo A. Lotufo, Layal Chaker, Isabela M. Bensenor Metabolites, 2025 Background: Recently, a new biomarker index that reflects inflammation and protein energy malnutrition has emerged as a predictor of mortality in cardiovascular diseases. The metabolic vulnerability index (MVX) derives from blood-based inflammation (IVX) and malnutrition (MMX) markers measured by nuclear magnetic resonance (NMR) spectroscopy. We aimed to explore the association of subclinical hypothyroidism and thyroid-related parameters with IVX, MMX, and MVX scores. Methods: This cross-sectional study used the baseline data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Individuals with normal thyroid function and subclinical hypothyroidism were included. Thyroid-related parameters—thyroid-stimulating hormone (TSH), free thyroxine (FT4), free triiodothyronine (FT3), the FT3–FT4 ratio, and antithyroperoxidase antibodies (TPOAb)—were the explanatory variables. The primary outcomes, MVX, MMX, and IVX scores, were analyzed as continuous variables. Linear regression analyses were performed for both univariate and multivariable models, with sensitivity and subgroup analyses applied to assess robustness. Findings: There were 3979 participants (51.4% female) with a mean age of 51.26 (SD: 9.02) years. After full adjustment for potential confounder variables, FT3 levels [B: −1.37 (−2.43;−0.31) p = 0.011] and the FT3–FT4 ratio [B: −0.90 (−1.79;−0.01) p = 0.047] were inversely associated with MVX scores. FT3 levels were also inversely associated with IVX [B: −1.32 (−2.39;−0.24) p = 0.017]. These results were consistent in euthyroid individuals and those with cardiometabolic diseases. In the sex-stratified analysis, FT3 levels were inversely associated with MVX, MMX, and IVX scores for men. Conclusion: Lower FT3 levels and the FT3–FT4 ratio were associated with a higher metabolic vulnerability in our cohort. Our study sheds light on the importance of metabolic surveillance in these patients, especially for men with cardiometabolic diseases.
Associations Between Subclinical Thyroid Dysfunction and Cardiovascular Risk Factors According to Age and Sex Oliver Baretella, Manuel R Blum, Nazanin Abolhassani, Heba Alwan, Lea Wildisen, Cinzia Del Giovane, Kali Tal, Elisavet Moutzouri, Bjørn O Åsvold, Anne R Cappola, Jacobijn Gussekloo, Massimo Iacoviello, Giorgio Iervasi, Misa Imaizumi, Stefan Weiler, Salman Razvi, José A Sgarbi, Henry Völzke, Suzanne J Brown, John P Walsh, Bert Vaes, Bu B Yeap, Robin P F Dullaart, Stephan J L Bakker, Maryam Kavousi, Graziano Ceresini, Luigi Ferrucci, Drahomir Aujesky, Robin P Peeters, Douglas C Bauer, Martin Feller, Nicolas Rodondi Journal of Clinical Endocrinology and Metabolism, 2025 Context Subclinical thyroid dysfunction (ScTD), comprising subclinical hypothyroidism (SHypo) and subclinical hyperthyroidism (SHyper), has been associated with increased risk for cardiovascular events. Objective To assess associations between ScTD and cardiovascular risk factors (cvRFs) according to age and sex. Methods This analysis of pooled participant data from large prospective cohort studies from the Thyroid Studies Collaboration assessed cvRFs (blood pressure [BP], lipid levels, high-sensitivity C-reactive protein [hs-CRP]) among participants aged 18 to 103 years with SHypo (thyroid-stimulating hormone [TSH] > 4.50 mU/L, normal fT4) and SHyper (TSH < 0.45 mU/L, normal fT4) vs euthyroid (TSH 0.45-4.50 mU/L). Results Of 69 006 participants (mean age 62 years, 55% women, 25% current smokers) from 16 international cohorts, 3748 (5.4%) had SHypo and 3428 (5.0%) had SHyper. In both women and men, systolic and diastolic BP were similar regardless of thyroid status. Exceptions were lower diastolic BP in women with SHyper compared to euthyroid participants (adjusted mean difference [aMD] −1.3 mmHg, 95% CI −2.0 to −0.5), and lower systolic BP in men with SHyper compared to euthyroid participants (aMD −3.1 mmHg, 95% CI −4.8 to −1.4). In both women and men, lipid levels (total, HDL, LDL-cholesterol, triglycerides) and hs-CRP were similar regardless of thyroid status. The only exception were women with SHyper who had lower LDL-cholesterol vs euthyroid (aMD −0.17 mmol/L, 95% CI −0.29 to −0.05). Conclusion Participants with ScTD and euthyroid participants have similar cvRFs and differences are arguably too small to explain the increased cardiovascular risk in ScTD observed in previous studies.
Branched-Chain Amino Acids, Alanine, and Thyroid Function: A Cross-Sectional, Nuclear Magnetic Resonance (NMR)-Based Approach from ELSA-Brasil Carolina Castro Porto Silva Janovsky, Vandrize Meneghini, William Tebar, Joao Roberto Maciel Martins, José Augusto Sgarbi, Patrícia de Fatima dos Santos Teixeira, Steven R. Jones, Michael J. Blaha, Peter P. Toth, Paulo A. Lotufo, Marcio S. Bittencourt, Raul D. Santos, Itamar S. Santos, Layal Chaker, Isabela M. Bensenor Metabolites, 2024 The association of thyroid function with essential and non-essential amino acids is understudied, despite their common metabolic roles. Thus, our aim was to evaluate the association of thyroid function with the levels of branched-chain amino acids (BCAAs—leucine, isoleucine, and valine) and of alanine in the general population. We utilized data from the São Paulo research center of ELSA-Brasil, a longitudinal population-based cohort study. Thyroid parameters included thyroid stimulating hormone (TSH), free T4 and free T3 levels, and the FT4:FT3 ratio. BCAAs and alanine were analyzed on a fully automated NMR platform. The current analysis included euthyroid participants and participants with subclinical hyperthyroidism and hypothyroidism. We used Pearson’s coefficient to quantify the correlation between thyroid-related parameters and amino acids. Linear regression models were performed to analyze whether thyroid parameters were associated with BCAAs and alanine levels. We included 4098 participants (51.3 ± 9.0 years old, 51.5% women) in this study. In the most adjusted model, higher levels of TSH were associated with higher levels of alanine, FT4 levels were inversely associated with isoleucine levels, FT3 levels were statistically significant and positively associated with valine and leucine, and the T3:T4 ratio was positively associated with all amino acids. We observed that subclinical hypothyroidism was positively associated with isoleucine and alanine levels in all models, even after full adjustment. Our findings highlight the association of subclinical hypothyroidism and thyroid-related parameters (including TSH, free T4, free T3, and FT4:FT3 ratio) with BCAAs and alanine. Further studies are needed to explore the mechanisms underlying this association. These insights contribute to our understanding of the influence of thyroid-related parameters on BCAA and alanine metabolism.
Potential Determinants of Thyroid Peroxidase Antibodies and Mortality Risk: Results From the ELSA-Brasil Study Vandrize Meneghini, William Rodrigues Tebar, Itamar Souza Santos, Carolina Castro Porto Silva Janovsky, Bianca de Almeida-Pititto, Marina Gabriela Birck, Paulo Andrade Lotufo, Alessandra Carvalho Goulart, José Augusto Sgarbi, Patrícia de Fátima dos Santos Teixeira, Gisela Tunes da Silva, Isabela Martins Benseñor Journal of Clinical Endocrinology and Metabolism, 2024 Context The presence of thyroid peroxidase antibodies (TPOAbs) may be considered as an indicator of adverse health outcomes. Objective We aimed to investigate the potential determinants of TPOAb levels and to analyze the association between TPOAb titers and the risk of all- and specific-cause mortality. Methods Baseline and longitudinal data of 13 187 participants from the ELSA-Brasil Study were analyzed. We investigated the association of TPOAb, detectability, positivity, and persistent positivity with sociodemographic and lifestyle factors using logistic regressions. Cox proportional hazards and Fine-Gray subdistribution hazard regression analyses were used to verify the association of TPOAbs with mortality. Results The determinants of TPOAb detectability and positivity were younger age, higher body mass index, female sex, and former and current smoking status. Black, mixed, and other self-reported races, intermediate and higher education, and heavy drinking were determinants of detectable and positive TPOAb levels. Female sex, White race, and former smoking were determinants of persistent TPOAb positivity at 2 visits, although only the female sex maintained its association at 3 visits. Moreover, after multivariate adjustment, there were associations between higher levels of TPOAbs and higher risk of cancer-related mortality among men, and TPOAb detectability and mortality by other causes among women. Conclusion Sociodemographic and lifestyle-related factors were determinants of multiple TPOAb categories. TPOAb levels were associated with mortality risk; however, the low mortality rate in this sample might have compromised this finding. We suggest further studies to explore the clinical importance of detectable TPOAb levels, not only its positivity, as a potential marker of inflammation.
Associations of TSH, free T3, free T4, and conversion ratio with incident hypertension: results from the prospective Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) Marina Gabriela Birck, Carolina C. P. S. Janovsky, Alessandra Carvalho Goulart, Vandrize Meneghini, Bianca de Almeida Pititto, José Augusto Sgarbi, Patrícia de Fátima dos Santos Teixeira, Isabela M. Bensenor Archives of Endocrinology and Metabolism, 2024 Objective To evaluate the association of TSH, free T3 (FT3), free T4 (FT4), and conversion (FT3:FT4) ratio values with incident hypertension. Materials and methods The study included data from participants of the ELSA-Brasil study without baseline hypertension. Serum TSH, FT4 and FT3 levels, and FT3:FT4 ratio values were assessed at baseline, and incident hypertension (defined by blood pressure levels ≥ 140/90 mmHg) was estimated over a median of 8.2 years of follow-up. The risk of incident hypertension was evaluated considering a 1-unit increase in TSH, FT4, FT3, and conversion ratio values and after dividing these variables into quintiles for further analysis using Poisson regression with robust variance. The results are presented as relative risks (RR) and 95% confidence intervals (CIs) before and after adjustment for multiple variables. Results The primary analysis incorporated data from 5,915 euthyroid individuals, and the secondary analysis combined data from all euthyroid individuals, 587 individuals with subclinical hypothyroidism, and 31 individuals with subclinical hyperthyroidism. The rate of incident hypertension was 28% (95% CI: 27%-29.3%). The FT4 levels in the first quintile (0.18-1.06 ng/dL) were significantly associated with incident hypertension (RR: 1.03, 95% CI: 1.01-1.06) at follow-up. The association between FT4 levels in the first quintile and incident hypertension was also observed in the analysis of combined data from euthyroid individuals and participants with subclinical thyroid dysfunction (RR: 1.04, 95% CI: 1.01-1.07). The associations were predominantly observed with systolic blood pressure levels in euthyroid individuals. However, in the combined analysis incorporating euthyroid participants and individuals with subclinical thyroid dysfunction, the associations were more pronounced with diastolic blood pressure levels. Conclusion Low FT4 levels may be a mild risk factor for incident hypertension in euthyroid individuals and persons with subclinical thyroid dysfunction.

The Relationship between Type 1 Diabetes Mellitus, TNF-α, and IL-10 Gene Expression Jesselina Francisco dos Santos Haber, Sandra Maria Barbalho, Jose Augusto Sgarbi, Rafael Santos de Argollo Haber, Roger William de Labio, Lucas Fornari Laurindo, Eduardo Federighi Baisi Chagas, Spencer Luiz Marques Payão Biomedicines, 2023 Type 1 diabetes mellitus (T1DM) is one of the major chronic diseases in children worldwide. This study aimed to investigate interleukin-10 (IL-10) gene expression and tumor necrosis factor-alpha (TNF-α) in T1DM. A total of 107 patients were included, 15 were T1DM in ketoacidosis, 30 patients had T1DM and HbA1c ≥ 8%; 32 patients had T1DM and presented HbA1c < 8%; and 30 were controls. The expression of peripheral blood mononuclear cells was performed using the reverse transcriptase–polymerase chain reaction in real time. The cytokines gene expression was higher in patients with T1DM. The IL-10 gene expression increased substantially in patients with ketoacidosis, and there was a positive correlation with HbA1c. A negative correlation was found for IL-10 expression and the age of patients with diabetes, and the time of diagnosis of the disease. There was a positive correlation between TNF-α expression with age. The expression of IL-10 and TNF-α genes showed a significant increase in DM1 patients. Once current T1DM treatment is based on exogenous insulin, there is a need for other therapies, and inflammatory biomarkers could bring new possibilities to the therapeutic approach of the patients.
