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

Recruiting now · Not applicable · Has a placebo group

Conditions studied: Refactory Warts

In brief

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.
