A prospective randomized controlled study of Mycobacterium Indicus Pranii vaccine, Measles Mumps Rubella vaccine and Vitamin D3 in extragenital cutaneous warts

DesignInterventional, prospective, four arm randomized control. SettingOutpatient department, Department of Dermatology, Venereology and Leprology, AIIMS Jodhpur (Rajasthan), India. ParticipantsTwo hundred patients. MethodsThe intervention administered in the groups were normal saline (A), vitamin D-3 (B), MIP (C), and MMR (D). The injections were given into the largest wart at 2-weekly intervals until complete clearance or for a maximum of seven sittings. Post-treatment clearance of the injected wart and the distant wart was compared on the basis of change in wart number, percentage clearance, and mean time to complete clearance. Side effects were recorded. ResultsA total of 197 patients were recruited. The mean percentage improvement in the injected and non-injected warts was 68.4% and 66.8%, respectively. Intention to treat analysis (ITT) showed that complete clearance of lesions in injected wart occurred in placebo, vit D-3, MMR, and MIP arms in 64%, 66%, 58%, and 55% patients, respectively (p > 0.05), while in the non-injected warts in 62%, 64%, 52%, and 53%, respectively (p > 0.05). The mean time to achieve complete clearance of wart was fastest in MIP at 7.1 weeks followed by MMR at 7.2 weeks, VIT D-3 at 7.4 weeks and in placebo group 7.8 weeks (p > 0.05). Side effects noted were fever, pain, erythema, and swelling which was highest in VIT D-3 group (p < 0.05). ConclusionThe efficacy of immunotherapies was comparable to placebo with minimal side effects.
