Efficacy of Chinese medicine in the adjuvant treatment of Hashimoto's thyroiditis with hypothyroidism: a systematic review and meta-analysis.

ABSTRACT

The quality of the studies was assessed using the Cochrane risk bias assessment tool and the results were analyzed using Review Manager 5.3 software. The evidence was also evaluated for its strength using GRADE. A total of 18 randomized controlled trials were included in the study, involving 1247 patients. The primary outcomes of this study included overall efficacy, effectiveness in treating specific symptoms, and the Traditional Chinese Medicine symptom score. The secondary outcomes included the levels of FT3, FT4, and TSH, the size of the thyroid gland, and any adverse events. The results of the meta-analysis showed that CHM combined with WM has a better curative effect and a more effective reduction in clinical symptoms than WM alone comprehensive efficacy [OR = 4.83; 95% CI (3.45, 6.76)], syndrome efficacy [OR = 5.95; 95% CI (3.94, 8.99)], TCM symptom score SMD = -1.49; 95% CI (-1.86, -1.11)], FT3 [SMD = 0.59; 95% CI (0.48, 0.71)], FT4 [SMD = 0.59; 95% CI (0.48, 0.71)], TSH SMD = -0.97; 95% CI (-1.35, -0.58)], and thyroid volume SMD = -0.25; 95% CI (-0.34, 0.15)]. The incidence of adverse events between the groups was not significantly different [OR = 1.00; 95% CI (0.14, 7.27)]. Because of the effectiveness of CHM, we support using CHM to improve clinical efficacy in the treatment of HTH. The results of our research suggest that the use of Chinese Herbal Medicine (CHM) in combination with Western Medicine (WM) may result in improved clinical efficacy in the treatment of hypothyroidism (HTH) compared to using WM alone.
