Area of Science:

  • Dermatology
  • Immunology

Background:

  • Warts are common skin infections caused by human papillomavirus (HPV).
  • Recalcitrant warts often resist conventional treatments like cryotherapy.
  • OK-432, a streptococcal preparation, is known for its immunomodulatory effects.

Observation:

  • Twelve patients with warts resistant to standard treatments were enrolled.
  • Treatment involved subcutaneous, intralesional, or combined OK-432 injections.
  • Patients were monitored for wart clearance and adverse events.

Findings:

  • Complete wart clearance was achieved in 75% (9/12) of patients.
  • Subcutaneous injection showed a 55.6% success rate, while intralesional injection had a 66.7% success rate.
  • Mild, transient side effects like fever and malaise were reported in some patients.

Implications:

  • OK-432 injection therapy presents a viable and effective option for recalcitrant warts.
  • Further research may optimize injection methods for improved efficacy.
  • This immunotherapeutic approach warrants consideration in clinical practice for challenging wart cases.
