Jet Injections With Candida Antigen for Wart Treatment: An Alternative Drug Delivery

Area of Science:

• Dermatology
• Pediatrics
• Immunology

Background:

• Warts are common pediatric skin infections caused by human papillomavirus (HPV).
• Intralesional immunotherapy, typically via needle injection, is a recognized treatment for recalcitrant warts.
• Traditional needle-based immunotherapy can cause pain and anxiety, especially in pediatric patients.

Purpose of the Study:

• To report a case of successful wart treatment using a novel needle-free immunotherapy delivery system.
• To evaluate the efficacy and tolerability of intralesional Candida antigen delivered via a needle-free jet injector for pediatric warts.

Main Methods:

• A 12-year-old boy with extensive warts received two sessions of intralesional Candida antigen.
• The antigen was administered using a needle-free jet injection device, avoiding traditional needles.
• Treatment outcomes were assessed by clinical resolution of warts.

Main Results:

• Complete resolution of warts was achieved after two sessions of needle-free immunotherapy.
• The treatment was well-tolerated and described as pain-free by the patient.
• The needle-free approach proved effective in this pediatric case.

Conclusions:

• Needle-free delivery of intralesional Candida antigen is a viable and less painful alternative for treating pediatric warts.
• This method offers a promising option for patients with needle phobia or those seeking less invasive treatments.
• Further studies are warranted to confirm the efficacy and applicability of this technique in a broader pediatric population.
