A comparative study of the efficacy and safety of intralesional measles, mumps, and rubella vaccine versus intralesional vitamin D3 for the treatment of warts in children

Intralesional measles, mumps, and rubella vaccine after failure of intralesional Candida antigen for the treatment of recalcitrant pediatric warts

Numerous studies have investigated the efficacy of intralesional immunotherapy for warts, but there are a lack of studies investigating the efficacy of alternative intralesional immunotherapies following failure of initial intralesional immunotherapy. In this retrospective study, we aimed to investigate the efficacy of intralesional measles, mumps, and rubella vaccine for the treatment of pediatric warts following failure of intralesional therapy with Candida antigen. Following intralesional measles, mumps, and rubella vaccine administration, 8/51 (15.5%) patients had complete resolution of their warts, 6/51 (12%) had near complete resolution, 19/51 (37%) had partial improvement, 12/51 (23.5%) had no change, and 6/51 (12%) had worsening. Although limited by retrospective nature and low sample size, our results demonstrate that intralesional immunotherapy with measles, mumps, and rubella vaccine provides an alternative therapeutic option for the treatment of recalcitrant pediatric warts in patients who fail to respond to intralesional Candida antigen.

Comparative study between intralesional injection of MMR, BCG, and candida albicans antigen in treatment of multiple recalcitrant warts

BACKGROUND

Cutaneous warts represent a challenging condition to treat.

OBJECTIVE

To evaluate the safety and efficacy of intralesional injection of MMR (mumps, measles, and rubella) antigen, BCG (bacillus Calmette-Guerin) vaccine, and candida antigen for the treatment of multiple warts.

METHODS

A total of ninety (90) clinically confirmed adult patients complaining of recalcitrant extragenital warts of various sizes and durations were recruited in this randomized clinical trial. They were divided into three groups (A, B, and C). Each group consisted of (30) patients. Group (A) subjects received intralesional MMR injections. Group (B) subjects received intralesional BCG injection and Group (C) received intralesional candida antigen injection.

RESULTS

Full clearance of warts was observed in (73.33%, 70%, and 43.33%) in groups A, B, and C, respectively. Infrequent side effects including pain, erythema, and minimal induration were reported in all groups but did not necessitate termination of treatment.

CONCLUSION

All the three modalities used demonstrated a simple, safe modality with low adverse events, and with no recurrence. To achieve an optimal response with an ideal immunotherapeutic agent and ideal dose, further comparative studies are warranted and on different populations and larger sample sizes.

Evaluation of the Efficacy of Intralesional Measles, Mumps, and Rubella Vaccine with Intralesional Vitamin D3 as Immunotherapies in the Treatment of Recalcitrant Cutaneous Warts in Adult- A Randomized Placebo-Controlled Study

Introduction:

Currently, various destructive and ablative treatment options are conventionally used for warts, but all of them are limited in some form by their adverse effects, high recurrences, suboptimal effectiveness, and the need to treat every wart. Lately, immunotherapy has emerged as a safe treatment relying on biological substances that modulate the immune system to achieve disease control.

Aims and Objectives:

We aimed at conducting a placebo-controlled study to compare the rate of efficacy of intralesional MMR vaccine with vitamin D3 in the management of recalcitrant extragenital warts in immune-competent adults. Follow-up was done at third and sixth month.

Materials and Methods:

Patients were divided into three groups, namely, group A, B, and C. Groups A, B, and C received intralesional MMR vaccine, vitamin D3 and normal saline, respectively, in the largest wart. The injections were repeated every 2 weeks, for a maximum of four injections.

Results:

Among injected warts, in group A, complete clearance was seen in 29 (87.8%) patients, partial clearance in two (6.1%) and no response in two (6.1%) patients. In group B, 24 (77.4%) patients, five (16.1%) patients, and two (6.5%) patients showed signs of complete, partial, and no clearance, respectively, in injected warts. Complete response in distant warts was seen in 25 (75.7%) patients in group A and 20 (64.5%) patients in group B. There was no statistically significant difference between responses of the two groups. In group C, only three (12.5%) patients had complete clearance in injected warts, and none in distant warts. Recurrence was seen in two (6.4%) patients, each in group B and C. However, for management of verruca plana MMR was found to be superior to vitamin D3.

Limitations:

Our study was limited by a small sample size, absence of immunological analysis, and limited follow-up period.

Conclusion:

MMR vaccine and vitamin D3 are equally effective and safe treatment option for multiple, recalcitrant warts, as well as warts on difficult to treat sites with minimal recurrence.

Management of Difficult-to-Treat Warts: Traditional and New Approaches

Warts are regularly treated by dermatologists, and while many respond readily to first-line treatments, others may represent a therapeutic challenge. Large, deep, numerous, and extensive warts; treatment-resistant lesions with higher risk for side effects, such as hypopigmentation; or patients unable to tolerate or comply with our treatment regimen, may need alternative treatment options. In this work we review the characteristics of select modalities that should be considered for difficult-to-treat warts. We discuss efficacy and tolerability data as well as practical features that can guide us to select the best treatment for every scenario. Novel approaches, still in an investigational phase, are also discussed to illustrate potential future directions of wart treatment.
