Conclusion: Patients with hypothyroidism prefer combination therapy (L-T3 + L-T4 or DTE) over L-T4 monotherapy. The strength of these findings justifies considering patient preferences in the setting of shared decision-making in the treatment of hypothyroidism.
PubMed 39290156 ↗Conclusion: Our study revealed that combined therapy and DTE lead to higher T3 and lower T4 levels, compared to T4 monotherapy in hypothyroidism. However, no significant effects on heart rate, lipid profile, or quality of life were noted. Given the heterogeneity of results, personalized treatment approaches are recommended.
PubMed 38877429 ↗Conclusion: Despite standard LT4 therapy, hypothyroidism remains associated with heightened risks of dementia and mortality. Adding T3 may more effectively mitigate these risks than LT4 alone, but further studies are needed to confirm the cognitive and survival benefits of T3-containing regimens.
PubMed 40579157 ↗Conclusion: Two RCTs could not demonstrate any difference in QoL or symptom scores when comparing DTE with other thyroid hormone substitutions. Future trials of DTE in patients with hypothyroidism should be based on adequate study designs, validated measures of QoL, patients with reduced QoL, and the assessment of biomarkers reflecting long-term adverse effects.
