Epicutaneous heat patch  safe and effective treatment of Warts

Local hyperthermia delivered by epicutaneous heat patches is effective, well-tolerated, safe, result in complete clearance of warts.

Hyperthermia is believed to be effective for treating warts using a hot water technique as well as an ultrasound hyperthermia technique. Recently, local hyperthermia has grabbed the attention of dermatologists for the treatment of cutaneous warts. A study published in the Journal of Drugs in Dermatology has shown that local hyperthermia delivered by epicutaneous heat patches is effective, well-tolerated, safe and may cause complete clearance of warts.

A wart is a small growth on the skin that may look like a solid blister or a small cauliflower. Types of wart include common warts, flat warts, pigmented warts, and plantar warts. Black dots in the wart are blood vessels that can lead to bleeding. Most warts disappear in 1 to 5 years without medical treatment, but treatment is available for warts that are large, numerous, or in sensitive areas. Treatments include salicylic acid, duct tape, cryotherapy, surgery, laser treatment, electrocautery, photodynamic therapy, chemical treatments, topical creams, cantharidin, and antigen shots.

In the present study, the investigators have performed an uncontrolled, proof of concept study by applying a novel, reproducible, epicutaneous heat patch to a target wart for 2 hours per day for 12 weeks. There were 15 evaluable participants. An untreated wart was also observed and measured. Wart measurements included the diameter in two dimensions, an investigator global assessment (IGA) score, wart clearance, and monitoring for adverse events as endpoints at week 12 (end of treatment) and week 24 (end of study).

The investigators observed complete clearance of both warts in  46.7% participants at week 24, However,  the small sample size and lack of independent control in each participant were the main limiting factors of the study.

The authors concluded that local hyperthermia delivered by epicutaneous heat patches was well-tolerated, safe, and achieved complete clearance in both treated as well untreated warts in 46.7% of participants at week 24 after 12 weeks of daily use.
