Treatment of cutaneous warts: an evidence-based review

Area of Science:

• Dermatology
• Virology
• Evidence-Based Medicine

Background:

• Cutaneous warts, caused by human papillomavirus (HPV), are common skin lesions requiring treatment for discomfort and to prevent spread.
• Current therapeutic options for warts lack uniform efficacy and virucidal properties, with limited data from controlled trials.
• Assessing treatment reproducibility and ruling out placebo effects are challenging due to insufficient evidence-based studies.

Purpose of the Study:

• To review and categorize current therapies for cutaneous warts based on evidence-based medicine.
• To classify treatments into first-, second-, and third-line options for various clinical wart types.
• To evaluate the efficacy and safety of different treatment modalities for HPV infections.

Main Methods:

• Literature review of evidence-based medicine studies on cutaneous wart treatments.
• Classification of therapies into first-line (medical), second-line (cryotherapy), and third-line (alternative options).
• Analysis of treatment outcomes for different clinical presentations of warts.

Main Results:

• First-line treatments include salicylic acid, silver nitrate, and glutaraldehyde for limited or short-duration warts.
• Cryotherapy is recommended as a second-line option for treatment failures or contraindications.
• Third-line therapies encompass various off-label options for recurrent or resistant lesions, often with significant drawbacks.

Conclusions:

• Combined cryotherapy and salicylic acid demonstrate significantly higher remission rates for cutaneous warts.
• Evidence-based data suggests a tiered approach to wart treatment, prioritizing established therapies.
• Further research is needed to establish the efficacy and safety of many alternative wart treatments.
