This randomized controlled trial evaluated the efficacy of 5-aminolevulinic acid photodynamic therapy (5-ALA-PDT) combined with recombinant human interferon alpha 2b (rhIFN-α2b) spray in 104 patients with refractory common and plantar warts. The intervention group showed a complete recovery rate of 90.20% compared to 62.26% in the control group (p = 0.002).

Key findings

  • The total effective rate was 96.08% in the intervention group versus 77.36% in the control group (p = 0.013).
  • Recurrence rates at 8 weeks were 2.17% in the intervention group compared to 24.24% in the control group.
  • At 6 months, recurrence rates were 4.35% in the intervention group versus 39.39% in the control group.

Why it matters

The study highlights a promising alternative treatment for common and plantar warts, particularly for patients with refractory cases, potentially improving patient outcomes and reducing recurrence rates.
