Efficacy and safety of Chinese patent medicine paiteling in condyloma acuminatum: A systematic review and meta-analysis.

ETHNOPHARMACOLOGICAL RELEVANCE: Condyloma acuminatum (CA) is a common sexually transmitted disease. Previous studies using randomized controlled trials (RCTs) have revealed that Paiteling (PTL), a Chinese patent medicine formula, can effectively relieve CA symptoms. However, the evidence needs to be more cohesive and there is a need for a clear summary of the existing RCTs to assess the overall efficacy and safety profile of PTL.

AIMS OF THE STUDY: This study aimed to conduct a comprehensive review and meta-analysis of RCTs, to examine the efficacy of PTL and physical therapies in CA.

MATERIAL AND METHODS: A literature search was conducted in multiple databases, including PubMed, MEDLINE, Cochrane Library, etc. up to December 1, 2022. Revman 5.4 and Stata 15.0 was used for data statistics and sensitivity analyses.

RESULTS: 31 trials with a total of 2868 patients were included in this review. The results showed that PTL plus physical therapies were significantly more effective than physical therapies used alone. (RR = 1.60, 95% CI [1.38, 1.86]; P < 0.00001). Subgroup analysis showed that the type of physical therapies, gender, and wart location might be the primary sources of heterogeneity. Additionally, PTL can reduce recurrence rates (RR = 0.27, 95% CI [0.19, 0.39]; P < 0.00001), improve the negative conversion rate of HPV (RR = 1.15, 95% CI [1.02, 1.30]; P = 0.02), and improve immune function. No severe adverse reactions or physical injuries were observed, making it a better choice for women planning to become pregnant.

CONCLUSION: Compared with physical therapies, PTL can effectively eliminate CA symptoms and reduce the recurrence rates with safety ensured. However, due to the heterogeneity and methodological shortcomings, large sample sizes and high-quality rigorous RTCs are still needed to strengthen this clinical evidence.
