Insights
Atherosclerotic disease is a significant risk factor for hyperthyroidism relapse in patients treated with antithyroid drugs (ATDs). Early identification and management of atherosclerosis are crucial for preventing relapse during ATD therapy.
Area of Science:
- Endocrinology
- Cardiovascular Medicine
- Internal Medicine
Background:
- Hyperthyroidism treatment with antithyroid drugs (ATDs) carries a risk of clinical relapse.
- Atherosclerotic disease is linked to hyperthyroidism, but its association with ATD relapse is not well understood.
Purpose of the Study:
- To investigate the relationship between atherosclerotic disease and relapse in patients with Graves' disease (GD) undergoing ATD treatment.
- To identify independent risk factors for drug reduction relapse in GD patients.
Main Methods:
- A cohort of 225 GD patients receiving initial ATD treatment was studied.
- Logistic regression and Kaplan-Meier survival analysis were employed to assess risk factors and relapse rates.
- Receiver Operating Characteristic (ROC) analysis evaluated the predictive accuracy of atherosclerotic disease.
Main Results:
- Atherosclerotic diseases, elevated FT4 levels, goiter, and anxiety scores were identified as independent risk factors for relapse.
- Patients with atherosclerotic disease, higher FT4, higher anxiety scores, or advanced goiter showed increased relapse risk.
- Atherosclerotic disease significantly improved the predictive accuracy for relapse.
Conclusions:
- Atherosclerotic disease is closely associated with hyperthyroidism relapse.
- Hyperthyroid patients with atherosclerosis require increased attention during ATD treatment to mitigate relapse risk.
Background:
Clinical relapse is a potential risk for traditional antithyroid drug (ATD) treatment in hyperthyroid patients. Evidence suggests that atherosclerotic disease is closely associated with hyperthyroidism, while the relationship between atherosclerosis and relapse remains unclear.
Methods:
Two hundred and twenty-five patients with GD who underwent ATD as their first treatment were studied; 88 and 137 patients were categorized as drug reduction relapse and drug reduction remission, respectively. Logistic regression was used to analyze risk factors of drug reduction relapse in patients with GD.
Results:
During a median of 48 months followed up 88 patients who relapsed. According to multivariate analyses, atherosclerosis related diseases, FT4, goiter, and anxiety rating scores are independent risk factors for drug reduction. According to K-M survival analysis, patients with atherosclerosis related diseases, FT4 > 18.82 pmol/L, anxiety rating scores > 23, and gradation of goiter ≥ Grade II had a higher risk of relapse than those with lower levels. ROC analysis shown atherosclerosis related diseases significantly improved the predictive accuracy of relapse.
Conclusions:
Atherosclerotic disease is closely related to the relapse of hyperthyroidism, ATD treatment in hyperthyroid patients with atherosclerosis should be given more attention.

The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
