Efficacy and Safety of Intralesional Injection of Tuberculin PPD in Treatment of Plantar Warts

Abstract Background: Many destructive and immunotherapeutic modalities have been used for the management of plantar warts; however, an optimal treatment with high efficacy and absent or low recurrence has not been explored to date. Tuberculin purified protein derivative (PPD) shown promising results for treatment of viral warts without ablation. Aim of Study: To evaluate the efficacy and safety of intralesional (IL) PPD in the treatment of plantar warts. Patients and Methods: Twenty patients with plantar warts were included in this study and divided into two equal groups; group I was treated using IL tuberculin PPD every 2 weeks, group II was treated with IL saline every 2 weeks, till complete clearance or for a maximum of 3 sessions. The patients were followed-up for a period of 6 months. Results: There was a statistically highly significant im-provement in the therapeutic group compared with control group. This modality was well tolerated, with no remarkable side effects and no recurrence in cured patients during follow up period. A significant positive correlation existed between the number of sessions and treatment response. There was a significant negative correlation between the number of lesions and response to treatment. Conclusion: Intralesional PPD is safe and effective treat-ment alternative for the treatment of plantar warts even if they are recalcitrant or multiple, with no post-procedural downtime and better results and patient satisfaction.
