Insights
Taoren Honghua Jian (THJ) significantly improved angina symptoms and quality of life in coronary artery disease (CAD) patients. This traditional Chinese medicine treatment also reduced inflammation markers by suppressing NLRP3 inflammasome activity.
Area of Science:
- Cardiovascular Medicine
- Traditional Chinese Medicine
- Immunology
Background:
- Coronary artery disease (CAD) is a leading cause of mortality worldwide.
- Inflammation, particularly involving the NLRP3 inflammasome, plays a critical role in the pathogenesis of atherosclerosis.
- Qi stagnation and blood stasis syndrome is a recognized pattern in Traditional Chinese Medicine (TCM) associated with CAD.
Purpose of the Study:
- To evaluate the clinical efficacy of Taoren Honghua Jian (THJ) in CAD patients with Qi stagnation and blood stasis syndrome.
- To investigate the effect of THJ on NLRP3 inflammasome expression in peripheral blood mononuclear cells (PBMCs).
- To assess THJ's impact on inflammatory cytokine levels in CAD patients.
Main Methods:
- A multicenter, double-blind, randomized controlled trial involving 120 CAD patients.
- Participants received either THJ granules or a placebo for four weeks.
- Clinical outcomes (TCMSS, SAQ), lipid profiles, NLRP3 inflammasome components (mRNA in PBMCs), and plasma inflammatory cytokines were measured.
Main Results:
- THJ significantly reduced Traditional Chinese Medicine Syndrome Scores (TCMSS) compared to placebo (P < 0.01).
- The THJ group demonstrated significant improvements in Seattle Angina Questionnaire (SAQ) scores across five domains (P < 0.01).
- THJ suppressed NLRP3 inflammasome component mRNA expression in PBMCs and lowered plasma levels of IL-1β, IL-2, and IL-18 (P < 0.01).
Conclusions:
- THJ is clinically effective in alleviating angina symptoms and enhancing the quality of life for CAD patients.
- THJ demonstrates anti-inflammatory effects by suppressing NLRP3 inflammasome activation and pro-inflammatory cytokine production.
- THJ shows potential as an effective adjuvant therapy for managing inflammation-driven coronary atherosclerosis.
Objective:
This multicenter, double-blind, randomized controlled trial sought to assess the clinical efficacy of Taoren Honghua Jian (THJ) in patients with coronary artery disease (CAD) exhibiting Qi stagnation and blood stasis syndrome, and investigated its effect on NLRP3 inflammasome expression in peripheral blood mononuclear cells (PBMCs).
Methods:
One hundred and twenty eligible CAD patients from three Shanghai hospitals were randomized to receive either the THJ granule (18.3 g, twice daily) or placebo for four weeks, with a four-week follow-up. Traditional Chinese Medicine Syndrome Score (TCMSS), Seattle Angina Questionnaire (SAQ), and lipid levels were measured before and after treatments. NLRP3 inflammasome components were examined in PBMCs using quantitative PCR, whereas plasma inflammatory cytokines were detected using ELISA.
Results:
A total of 120 participants participated in the trial. The THJ group showed reduced TCMSS compared to the placebo group (P < 0.01). After four weeks of intervention, the THJ group scored considerably higher on five SAQ aspects compared to the placebo group (P < 0.01). However, lipid levels showed no significance. In PBMCs, THJ lowered mRNA expression of NLRP3 inflammasome components (NLRP3, ASC, caspase-1, IL-1β, IL-18) (P < 0.01). Patients in the THJ group showed significantly lower plasma levels of IL-1β, IL-2, and IL-18 following therapy compared to the placebo group (P < 0.01).
Conclusion:
THJ reduces angina symptoms and improves quality of life in CAD patients, which suggests that it suppresses NLRP3-related transcriptional activity and hence reduces pro-inflammatory cytokine production. These data suggest that THJ might be an effective adjuvant treatment for inflammation-driven coronary atherosclerosis.
