Local Hyperthermia Combined With Topical 3% Hydrogen Peroxide for Refractory Viral Warts

26. april 2026 opdateret af: Gao Xinghua, First Hospital of China Medical University

Randomized Single-blind Parallel Controlled Clinical Trial of Hyperthermia Combined With Topical 3% Hydrogen Peroxide for Refractory Viral Warts

  1. Background of the Problem Viral warts result from infection of the skin or mucous membranes by human papillomavirus (HPV). Some patients develop refractory cases due to abnormal immune function, persistent viral presence, or recurrent warts. The clinical challenge in treating refractory viral warts lies in the limited effectiveness of single therapeutic approaches, high recurrence rates, and the fact that a significant proportion of patients are infected with high-risk or special HPV subtypes. These factors necessitate combined multi-modal treatments and genetic etiological screening.

  2. Current Treatment Status Thermotherapy (44°C ± 2°C, 30 minutes per session): Studies have demonstrated that it can stimulate the activation of local immune cells (such as Langerhans cells), thereby enhancing antiviral immune responses.

    Hydrogen peroxide: It possesses antibacterial properties and promotes tissue repair. In keratinocytes, it can induce thermally induced pyroptosis, thereby enhancing the efficacy of antiviral treatment.

  3. HPV genotyping Refractory viral warts are often associated with infection by specific high-risk or low-risk HPV subtypes (e.g., HPV 16, 18, 2, 4, etc.). HPV genotype is closely linked to treatment outcomes and recurrence rates.
  4. Relevant pathogenic gene screening This involves exploring intrinsic patient susceptibility, such as genetic polymorphisms related to immune function (e.g., HLA typing or Toll-like receptor-related genes). It also includes screening for rare gene mutations, such as mutations in the GATA2, IL2RG, and DOCK8 genes, which lead to impaired viral clearance and a propensity to develop multiple viral warts.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Trial group
Local hyperthermia combined with hydrogen peroxide
Enhed: An infrared hyperthermia device
(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 target warts(largest and most severe warts).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 24 weeks.
Medicin: Hydrogen Peroxide 3 % Topical Solution
Dressing: Dress with a cotton ball soaked in 3% hydrogen peroxide one hour prior to each hyperthermia session. Local Hyperthermia treats the target warts(largest and most severe warts), while medication addresses all warts.
Placebo komparator: Control group
Local hyperthermia combined with normal saline
Enhed: An infrared hyperthermia device

Medicin: Normal Saline (NS)
The control group used normal saline as the placebo for wet compress, and the hyperthermia treatment was the same as that of the trial group.
