Intralesional vitamin D3 versus Candida antigen immunotherapy in the treatment of multiple recalcitrant plantar warts: A comparative case–control study

Efficacy of Intralesional Candida Injection in the Treatment of Cutaneous Warts: A Systematic Review and Meta-Analysis

Recent studies that examined the treatment efficacy of Candida antigen injection for both non-genital and genital warts yield inconsistent results. To address this, a systematic review and meta-analysis was conducted, comparing the treatment response between Candida antigen injection therapy and other intralesional immunotherapies across all types of warts. PubMed, Cochrane Library, and Embase were searched for relevant randomized controlled trials (RCTs) from inception to 16 September 2023, and 24 eligible RCTs were identified. A protocol was developed using the PRISM A-P checklist. In terms of complete clearance, intralesional Candida injection therapy demonstrated a significant improvement compared with saline (risk ratio [RR] 5.39; 95% confidence interval [CI] 3.49-8.33; I2=0%). However, no statistically significant differences were observed when compared with other therapies such as mumps-measles-rubella vaccines, purified protein derivative, vitamin D3, bivalent human papillomavirus vaccine, and zinc sulphate. Adverse effects associated with intralesional Candida therapy were generally reported as mild and manageable. In conclusion, intralesional Candida injection therapy for cutaneous warts may exhibit a superior complete and distant response rate. Nevertheless, owing to a limited sample size and other limitations, future research should aim for larger studies to provide more conclusive evidence.

Intralesional acyclovir versus intralesional Hepatitis-B vaccine in treatment of resistant plantar warts: a randomized controlled trial

Treating plantar warts is still a challenging problem with a long list of diverse treatment options that none of them seems to be definitive. To evaluate the effectiveness of intralesional acyclovir versus intralesional Hepatitis-B vaccine (HBV) in treatment of multiple resistant plantar warts. Forty-eight patients with resistant plantar warts completed the study with no dropouts. They were randomized into 3 groups; group(A) receiving intralesional HBV, group (B) receiving intralesional acyclovir and group (C) receiving intralesional saline as a control group over 5 biweekly sessions or until wart clearance. Clinical outcome was assessed through sequential digital lesion photographing upon each visit. Treatment related adverse reactions were recorded. 43.8%, 37.5% & 18.7% of Groups A, B &C respectively showed a complete response. pain was obvious in 100% and 56.3% of cases receiving intralesional acyclovir and HBV respectively. Up to the 6 month follow up period, none of the complete responders in all groups returned with a recurrence. Both acyclovir and HBV showed comparable efficacy and seem to be promising options for treating plantar warts being safe, affordable, and theoretically safe in immunocompromised cases.

Systematic Review of Intralesional Therapies for Cutaneous Warts

Intralesional therapies are used for recalcitrant warts, but no Food and Drug Administration-approved treatment exists nor is there consensus regarding the most efficacious therapy. Therefore, this systematic review aims to summarize efficacy and adverse events reported in 62 randomized controlled trials (RCTs) of intralesional therapies for cutaneous warts. The most studied intralesional therapies included measles, mumps, rubella (MMR) vaccine (n = 24 studies), purified protein derivative (PPD) (n = 19 studies), vitamin D3 (n = 15 studies), and Candida antigen (n = 14 studies). Most studies included adult and pediatric patients or adults alone, with only 4 studies on pediatric patients alone. MMR vaccine was the most studied treatment (n = 853 patients). MMR had a complete response rate of 27-90%. The next most common treatment, PPD, had a complete response rate of 45-87%. Other treatments included Candida antigen and vitamin D3, with complete response rates of 25-84% and 40-96%, respectively. The most frequent side effects were injection-site reactions and flu-like symptoms. This systematic review represents a useful summary of intralesional therapy RCTs for clinician reference. This study also highlights the lack of large multi-institutional RCTs, despite many patients being treated for this widespread problem.

Comparative Study Among CO 2 Laser, Intralesional Vitamin D3, and Combined Intralesional Vitamin D3 and CO 2 Laser in Treatment of Palmoplantar Warts

BACKGROUND

Many therapeutic modalities are used for palmoplantar warts; whether destructive, such as chemical cautery, electrocautery, cryocautery, surgical removal, and laser ablation, or immunotherapeutic, stimulating the immune system against the virus such as intralesional vitamin D3 injection.

OBJECTIVE

To compare the efficacy of intralesional vitamin D injection combined with CO 2 laser to the efficacy of either modality alone.

PATIENT AND METHODS

Eighty age- and sex-matched patients with palmoplantar warts were divided into 4 groups: Group A received intralesional vitamin D3 injections, group B received ablative CO 2 laser, group C received CO 2 laser and intralesional vitamin D3 injection, and group D (control group) were injected intralesionally with normal saline. Assessment was performed clinically, photographically, and dermoscopically before and after treatment to evaluate the response, and then, another assessment was performed after 3 months to detect any recurrence.

RESULTS

Complete clearance was seen in 90% of cases in group C, in 80% in group A, and in 75% in group B with no statistically significant difference.

CONCLUSION

Intralesional vitamin D, CO 2 laser, and the combination show comparable efficacy and recurrence rates. Intralesional vitamin D maybe a better option for people with a relative contraindication to CO 2 laser.

Intralesional Vitamin D3 Versus Bleomycin for Difficult-to-Heal Palmoplantar Warts: A Comparative Study

Introduction

Difficult-to-heal or recalcitrant palmoplantar warts are notoriously resistant to treatment, making treatment difficult and challenging. To improve the outcome and overcome the difficulties, various treatment options have been tried, but none is gold standard. Many comparative studies have been undertaken to assess the efficacy of various drugs; however, none of them are standardized, and no single treatment is effective. Various comparative efficacy studies have been conducted but, to the best of our knowledge, no study has been conducted comparing intralesional (IL) injection (inj) vitamin D3 (Vit D3) with the chemotherapy drug IL inj Bleomycin for difficult-to-heal palmoplantar warts. We conducted a trial to evaluate the efficacy of IL inj Vit D3 versus IL inj Bleomycin in the treatment of difficult-to-heal palmoplantar warts. The purpose of this study was to compare the efficacy of IL inj vitamin D3 versus IL inj Bleomycin as biological response modifier therapy in difficult-to-heal palmoplantar warts.

Materials and Methods

A cohort of 48 patients with difficult-to-heal warts were consecutively assigned to one of two groups: Group 1 IL inj Vit D3 (0.2-0.5 mL inj vitamin D3 600,000 IU solution 15 mg/mL) or Group 2 IL inj Bleomycin (0.2-0.4 mL of 1 U/mL solution) for a maximum of four treatments spaced 2 weeks apart, with a maximum of five warts treated at each visit for both groups. Warts were measured at baseline and at each subsequent visit. Wart's resolution was measured as 1-25%, 2-50%, 3-75%, and 4-100% reduction. Patients were followed-up for 3 months after treatment.

Results

All the 48 patients completed the study, with 26 receiving IL inj Vit D3 with complete resolution in 88.5%, partial resolution in 11.5%, and side effects in 6.2%. In 22 patients receiving IL inj Bleomycin, 95.5% had complete resolution, 4.5% had partial resolution, and 8.2% had side effects. Maximum resolution was observed in the third session. We found no recurrence after 3 months.

Conclusion

IL inj Vit D3 and IL inj Bleomycin are both safe and effective in treating difficult-to-heal palmoplantar warts with better outcomes and patient satisfaction. IL Bleomycin was significantly more effective than IL Vit D3, although the difference was not statistically significant.

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

DESIGN

Interventional, prospective, four arm randomized control.

SETTING

Outpatient department, Department of Dermatology, Venereology and Leprology, AIIMS Jodhpur (Rajasthan), India.

PARTICIPANTS

Two hundred patients.

METHODS

The intervention administered in the groups were normal saline (A), vitamin D₃ (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.

RESULTS

A 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 D₃ , 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 D₃ 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 D₃ group (p < 0.05).

CONCLUSION

The efficacy of immunotherapies was comparable to placebo with minimal side effects.

A comparative clinico-dermoscopic study of intralesional injection of combined digoxin and furosemide, Candida antigen, and vitamin D3 for multiple warts

BACKGROUND

Immunostimulatory and antiproliferative therapies have been widely used for the treatment of multiple warts. Recently, anti-HPV activity of ionic contra viral therapy (ICVT) which is comprised of combined digoxin and furosemide has been demonstrated.

AIM

To evaluate and compare the effectiveness and safety of intralesional injection of Candida antigen, vitamin D3, and combined digoxin and furosemide in the treatment of multiple warts.

PATIENTS AND METHODS

Seventy-five patients with numerous warts were randomly assigned to one of three equal groups: Candida antigen, vitamin D3, or a combination of digoxin and furosemide. In the Candida antigen group, injections into the biggest wart were done. In the vitamin D3 and combined digoxin/furosemide groups, the agent was injected into each wart with a maximum of five injected warts. Injections were repeated every 2 weeks until clearance or for a total of five sessions.

RESULTS

There was a statistically significant difference in the overall therapeutic response among the studied groups in favor of the intralesional Candida antigen group (60%), followed by the vitamin D3 group (48%) and the ionic contraviral therapy group (28%) (p = 0.02). However, the difference between both Candida antigen and vitamin D groups was not significant (p = 0.59).

CONCLUSIONS

Intralesional Candida antigen immunotherapy and vitamin D3 antiproliferative therapy are significantly more effective than ICVT.

LIMITATIONS

Short follow-up period and relatively small sample size.

Intralesional Candida albicans antigen versus intralesional zinc sulfate in treatment of cutaneous warts

Immunotherapy represents a promising therapeutic option for treatment of warts. Different concentrations of Candida antigen (1/100 and 1/1000) and zinc sulfate 2% were not previously compared regarding their efficacy in treatment of cutaneous warts. The present study compared the safety and efficacy of intralesional candida antigen versus intralesional 2% zinc sulfate for treatment of cutaneous warts. This prospective controlled clinical trial included one hundred and five patients presented with common, plantar, and plane warts. Patients were divided randomly into three groups, each group included 35 patients. Group 1 were treated with intralesional candida antigen (Ag) 1/100, Group 2 were treated with intralesional candida Ag 1/1000, and Group 3 were treated with intralesional zinc sulfate 2%. This study found that target warts of group 1 displayed higher rate of complete clearance compared to group 2 and group 3 (94.3%, 77.1, 74.2%), respectively. The present study concluded that intralesional immunotherapy with Candida antigen was more effective than Intralesional 2% zinc sulfate in treatment of cutaneous warts and less painful. Clinical trial registration number is (Clinical Trials.gov Identifier: NCT03158168).

Effect of 5-Aminolevulinic Acid Photodynamic Therapy with Transfer Factor Capsules in the Treatment of Multiple Plantar Warts

BACKGROUND

Plantar warts are a common cutaneous disease of the sole of the foot caused by human papillomavirus. Photodynamic therapy has gained increasing attention in the treatment of plantar warts.

OBJECTIVE

To investigate the effect of photodynamic therapy combined with transfer factor capsules in the treatment of multiple plantar warts.

METHODS

Sixty-one patients with multiple plantar warts who visited our outpatient department from September 2017 to August 2019 were randomly divided into two groups. Twenty-three patients received photodynamic therapy (treatment group) and thirty-eight received cryotherapy (control group). Both groups also received immune modulator transfer factor capsules. Skin lesion score, numeric rating scale- (NRS-) 10 score, recurrence rate, adverse reactions, and Dermatology Life Quality Index (DLQI) were analyzed in both groups.

RESULTS

The mean skin lesion score improved from 13.39 ± 3.88 before treatment to 1.48 ± 2.50 after the last treatment in the treatment group and from 12.47 ± 2.99 before treatment to 4.47 ± 3.67 after the last treatment in the control group. The success rate after 3 months of treatment was 86.96% in the treatment group and 39.47% in the control group. After 3 months of follow-up, the recurrence rate was significantly lower in the treatment group (20%) than in the control group (53.33%). The mean DLQI score at three months after treatment was significantly lower in the treatment group (3.61 ± 1.16) than in the control group (6.31 ± 2.59).

CONCLUSION

Photodynamic therapy combined with immunomodulators significantly increased the cure rate and reduced the recurrence rate of multiple plantar warts compared with traditional cryotherapy combined with immunomodulators.

Intralesional immunotherapy for non-genital warts: A systematic review and meta-analysis

Background

Intralesional immunotherapy has been reported to be effective for warts and to show good safety profiles, but this has not yet been systematically studied.

Aims

To determine the efficacy and safety of intralesional immunotherapy for treating non-genital warts.

Methods

We comprehensively searched the MEDLINE, Embase, Web of Science and Cochrane Library databases from the times of their inception to January 3, 2020. The primary outcome was the rate of complete response of all lesions. The distant complete response rate of warts located in an anatomically different body part and the recurrence rate were also analyzed.

Results

A total of 54 prospective studies was ultimately included. The immunotherapeutic agents used were Mycobacterium w vaccine, measles, mumps and rubella vaccine, purified protein derivative, Candida antigen, interferon, bacillus Calmette-Guérin vaccine and others. The pooled rate of complete response among all patients with non-genital warts treated using intralesional immunotherapy was 60.6% (95% confidence interval 54.8–66.5%). The pooled recurrence rate was 2.0% (95% confidence interval, 1.1–2.9%). All reported adverse events were mild and transient.

Limitations

The heterogeneity among studies

Conclusion

Intralesional immunotherapy is suggested for use in patients with multiple warts, given its promising results, good safety profile and low recurrence rate.

Intralesional immunotherapy for multiple recalcitrant plantar warts: Candida antigen is superior to intralesional purified protein derivative

BACKGROUND

Treatment of recalcitrant plantar warts represent a highly challenging issue for both patients and physicians. Candida antigen and purified protein derivative (PPD) have shown promising efficacy in the treatment of warts, however no previous studies have compared both antigens for recalcitrant plantar warts.

AIM

To assess the efficacy and safety of intralesional Candida antigen versus intralesional PPD in the management of recalcitrant plantar warts.

PATIENTS AND METHODS

The study included 120 adult patients with multiple recalcitrant plantar warts. They were randomly assigned to one of three groups; Candida antigen, PPD, or normal saline. Injections into the largest wart were repeated every two weeks until clearance or for a maximum of 5 sessions.

RESULTS

Complete wart clearance was reported in 33 patients (82.5%) of the Candida antigen group, in 22 patients (55.6%) of the PPD group, and in one patient (5%) of the control saline group. A statistically significant difference was found between the studied groups in favor of Candida antigen. Adverse effects were mild and insignificant in the 3 groups.

CONCLUSIONS

Intralesional antigen immunotherapy by Candida antigen or PPD is a promising, safe, and cost-effective therapeutic option for multiple recalcitrant plantar warts, with statistically significant superiority of Candida antigen. This article is protected by copyright. All rights reserved.

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.

Intralesional Measles, Mumps, and Rubella Vaccine Versus Intralesional Candida Antigen in the Treatment of Common and Plantar Warts

BACKGROUND

Intralesional immunotherapy has been effectively used in the treatment of warts; however, comparative studies between different antigens are limited.

OBJECTIVE

To evaluate the efficacy and safety of intralesional measles, mumps, and rubella (MMR) vaccine compared with intralesional Candida antigen for the treatment of multiple common and plantar warts.

METHODS

Sixty-eight adult patients with multiple common and plantar warts were randomly assigned into two groups, each containing 34 patients. The first group received intralesional MMR vaccine, while the second group received intralesional Candida antigen. Each treatment was injected into the largest wart at 2-week intervals until complete clearance or for a maximum of 5 sessions.

RESULTS

The overall therapeutic response was higher in the Candida antigen group (73.5%) compared with the MMR group (67.7%); however, the difference was not statistically significant. Complete clearance of common warts was higher in the Candida antigen group, while that of plantar warts was higher in the MMR group. Adverse effects were transient and well tolerated in both groups. No recurrence was detected during the 6-month follow-up period.

CONCLUSION

Intralesional MMR and intralesional Candida antigen showed comparable efficacy and safety in the treatment of common and plantar warts.

Topical treatment for plantar warts: A systematic review

There are a wide variety of treatments for plantar warts, but none has been shown to be effective in all patients. We aimed to perform a systematic review of the efficacy of different topical treatments on plantar warts. Systematic electronic searches (Pubmed, Cochrane Library, Embase, and Web of Science) were conducted in April 2020. Meta-analyses, systematic reviews, and retrospective or prospective clinical trials of the effects of topical and nonsurgical treatments of plantar warts were included. Two authors performed the study selection and data extraction. Any discrepancies between the two reviewers were discussed with a third reviewer. Forty-four studies were included. The average cure rates of the most frequent treatments were variable across the studies: cryotherapy (45.61%), salicylic acid (13.6%), cantharidin-podophyllin-salicylic acid formulation (97.82%), laser (79.36%), topical antivirals (72.45%), intralesional bleomycin (83.37%), and intralesional immunotherapy (68.14%). Twenty-two studies (50%) had a level of evidence 1b and grade of recommendation A, five studies (11.4%) had a level of evidence 2b and grade of recommendation B, two studies (4.5%) had a level of evidence 3b and grade of recommendation B, and 15 studies (34,1%) with a level of evidence 4 and grade of recommendation C. First-choice treatments for common warts, such as cryotherapy and salicylic acid, have low-cure rates for plantar warts. Other treatments, such as CPA formulation, immunotherapy, and intralesional bleomycin, which have compassionate use, have higher cure rates. This review should stimulate future high-quality research to evaluate these specialized treatments.

Efficacy and safety of intralesional injection of vitamin D3 versus tuberculin PPD in the treatment of plantar warts: A comparative controlled study

BACKGROUND

Several destructive and immunotherapeutic methods are used in treatment of plantar warts, but an effective method with no or reduced recurrence has not been found till now.

OBJECTIVES

To evaluate the efficacy and safety of intralesional (IL) vitamin D₃ (Vit.D₃ ) injection vs IL tuberculin purified protein derivative (PPD) injection in the treatment of plantar warts.

METHODS

Sixty patients with plantar warts were randomized into 3 equal groups: group I treated using IL tuberculin PPD every 2 weeks, group II treated using IL Vit.D₃ every 4 weeks, and group III treated with IL saline every 2 weeks till complete clearance or for a maximum of 3 sessions. The follow-up period was 6 months.

RESULTS

There was a statistically significant improvement in therapeutic groups than control with more significant improvement in group II than I. Regarding number of sessions required for complete response, there was a positive significant correlation in both groups, but more significant in group I. There was a negative correlation between the number of lesions and the response to treatment in both groups. Group II showed significantly better response to treatment in male patients. Both modalities were well tolerated, with no remarkable side effects and no recurrence in cured patients of both groups.

CONCLUSIONS

Both IL PPD and Vit.D₃ injection are safe and effective for treatment of plantar warts even recalcitrant or multiple, with no postprocedural downtime, better results, and patient satisfaction. IL Vit.D₃ injection has a superior advantage than PPD.

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

BACKGROUND

Intralesional vitamin D3 has recently emerged as a new treatment for cutaneous warts. The use of the measles, mumps, and rubella (MMR) vaccine for this purpose is an established modality. However, relevant data on the efficacy of either the MMR vaccine or vitamin D3 as immunotherapy for cutaneous warts in the pediatric population are limited.

OBJECTIVES

To compare the efficacy and safety of intralesional injections of MMR vaccine to intralesional injections of vitamin D3 in children aged 8-16 years with multiple warts.

METHODS

A total of 74 children were randomly allocated into two groups. Group A patients received intralesional MMR vaccine into the largest wart, and group B received intralesional vitamin D3 into the largest wart. The injections were repeated every 4 weeks until clearance or for a maximum of three treatments. After the last injection, children were followed up every 2 weeks for 3 months, and at the sixth month, a final clinical assessment was conducted.

RESULTS

Of 74 children, 60 completed the study, with 30 children in each group. Complete clearance of the injected wart was observed in 26 (86.67%) patients in the MMR group (group A) and 23 (76.7%) patients in the vitamin D3 group (group B). Distant warts cleared in 23 (76.7%) patients in group A compared to 20 (66.6%) patients in group B. There was no significant difference between groups. No recurrence was seen in group A, whereas two (6.6%) children in group B exhibited recurrence in the ensuing 6-month follow-up. The most common adverse events were injection site pain and swelling.

CONCLUSION

Both intralesional MMR and vitamin D3 are safe, generally well-tolerated, and equally effective in children for the treatment of cutaneous warts.

A comprehensive review of treatment options for recalcitrant nongenital cutaneous warts

Introduction: The treatment of recalcitrant nongenital cutaneous warts has always been challenging for dermatologists as they often recur and relapse. Multiple treatment options have been investigated to improve the outcome. This review provides an overview of the current treatment modalities and summarizes the efficacy and side effects of each treatment option for recalcitrant nongenital cutaneous warts.Methods: A PubMed search was performed through July 2019 to include all English language reports investigating the treatment for recalcitrant nongenital cutaneous warts, regardless of design.Results: A total of 144 studies were included in this review. The treatment options for recalcitrant nongenital cutaneous warts can be divided into three groups: destructive treatment, immunotherapy, and cytotoxic agents. Although both destructive therapies and cytotoxic agents demonstrated high complete response rates, immunotherapy, which is a minimally invasive method, was superior in terms of the clearance of distant warts. Intralesional mumps-measles-rubella injections and purified protein derivatives currently demonstrate high efficacy with well-established clinical evidence.Conclusions: Many upcoming treatment modalities, especially immunotherapy, are promising. However, more comparative studies are required to verify the efficacy and safety profile.
