Randomized Controlled Clinical Trial of Hyperthermia and Hydrogen Peroxide 3% in the Treatment of Cutaneous Warts

Mild local Hyperthermia with a certain temperature range has been successfully used to treat some diseases. The warm treatment is usually "all or nothing". "All" means that all viral warts are removed after "warm" treatment, including rashes in non-treated areas. "Nothing" means that some viral warts do not respond to heat. Therefore, further enhancing the therapeutic effect of warmth and improving the reaction of some patients is the priority. Cellular experimental studies have found that low concentrations of dioxygen can promote the secretion of a keratinocyte series of inflammatory factors induced by warming. A randomized parallel control design was used to compare the efficacy of hyperthermia combined with hydrogen peroxide therapy and single use of hyperthermia and hydrogen peroxide alone in the treatment of viral warts. Primary analysis: Modified ITT (all randomized patients receiving ≥1 treatment).Missing data: Multiple imputation using chained equations (MICE) .Between-group comparisons: ANOVA with Tukey posthoc test for continuous variables; Chi-square with Bonferroni correction for categorical variables.Survival analysis: Cox proportional hazards model adjusted for baseline lesion size

Inclusion criteria: The participants were between 16 and 65 years of age, had a clinical diagnosis of viral warts (including common warts, plantar warts, or condyloma acuminatum), and could understand and sign informed consent. Exclusion criteria: presented with clinically atypical warts; had immunocompromised status or a history of HIV infection; received HPV vaccination within the past 6 months; used immunomodulators, immunosuppressants, or systemic corticosteroids within defined timeframes (4 months and 1 month, respectively); underwent local therapies (e.g., laser, cryotherapy, retinoids) on or near warts within protocol-specified intervals; had a history of cutaneous malignancies or current precancerous lesions; exhibited active dermatologic/systemic diseases (e.g., psoriasis, eczema) or skin conditions (e.g., sunburn) potentially increasing study risks; or were deemed ineligible by investigators for other medical or logistical reasons.
