Hyperthermia treatment (hyperthermia) refers to treating diseases with temperature (39-45 ° C) beyond normal body temperature,. It has been reported that local warming at 44 ° C is able to effectively mobilize the body's immunity and clear HPV infected lesions, such as condyloma acuminatum and verruca vulgaris, etc.
Hydrogen peroxide (H2O2) is a commonly used disinfectant for skin debridement. It has been reported that high concentration of H2O2 (45% H2O2) is effective in the treatment of warts vulgaris, however, high concentration of H2O2 will cause more local pain, itching and burning sensation. 3% hydrogen peroxide is commonly used as skin debridement disinfectant.
The purpose of the study is to evaluate the efficacy and safety of 44℃ hyperthermia combined with 3% hydrogen peroxide in treating verruca virus.
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

Counted across the registry records on this site, refreshed daily.
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 .
Exclusion criteria: presented with clinically atypical warts; had status or a history of infection; received HPV vaccination within the past 6 months; used immunomodulators, immunosuppressants, or systemic 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 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.
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Device: Local Hyperthermia at 44℃
As an experimental arm
Drug: Hydrogen Peroxide 3 % Topical Solution
Undergo the hyperthermia treatment of the Local Hyperthermia Group and the dressing treatment of the 3% Hydrogen Peroxide Group. Apply the 3% hydrogen peroxide dressing 1 hour before each hyperthermia session. Local Hyperthermia treats the target warts(largest and most severe warts), while medication addresses all warts.
Drug: Hydrogen Peroxide 3 % Topical Solution · Device: Local Hyperthermia at 44℃
Dressing: Like the Local Hyperthermia Group, use a cotton ball soaked in 3% hydrogen peroxide. Irradiation: For seven sessions in three weeks, use simulated infrared light (without heat) with the same frequency as the Local Hyperthermia Group. Local Hyperthermia treats the target warts(largest and most severe warts), while medication addresses all warts.
(Patent No: ZL 200820231952.4, Model: YY-WRY-V01, Liaoning Yanyang Medical Instrument Co., Ltd., China) An infrared hyperthermia device was used to apply local hyperthermia at 44°C to the largest wart. The device includes a heating source, an infrared temperature monitor, an adjusting arm, a control circuit for temperature stabilization, and a display. It uses a tungsten-halogen lamp (wavelength: 760-2300 nm, peak at 1200 nm) to maintain the temperature of a 0.5\*0.5 cm skin area within ±0.1°C using a non-contact infrared feedback system.Hyperthermia: Conduct 44-degree Celsius, 30-minute sessions. Do it daily for the first 3 days, then 2 sessions every 7 days for 3 weeks, for a total of 7 sessions. Dressing: Apply a cotton ball soaked in 0.9% saline to the warts, wrap it with plastic film for 1 hour, and do this once a day for 6 weeks. Local Hyperthermia treats the target warts(largest and most severe warts), while medication addresses all warts.
