Vaccines in Dermatology-Present and Future: A Review

Dermatological vaccines have emerged as critical tools in preventing and managing a wide spectrum of skin conditions ranging from infectious diseases to malignancies. By synthesizing evidence from existing literature, this review aims to comprehensively evaluate the efficacy, safety, and immunogenicity of vaccines used in dermatology, including both approved vaccines and those currently being researched. Vaccines discussed in this paper include those targeting dermatoses and malignancies (e.g., acne vulgaris, atopic dermatitis, and melanoma); infectious diseases (e.g., human papillomavirus (HPV); varicella zoster virus (VZV); herpes zoster (HZ); warts; smallpox; mpox (monkeypox); hand, foot, and mouth disease (HFMD); candidiasis and Group B Streptococcus (GBS); and neglected tropical diseases (e.g., Buruli ulcer, leprosy, and leishmaniasis). Through this review, we aim to provide a detailed understanding of the role of vaccines in dermatology, identify knowledge gaps, and propose areas for future research.

Unveiling the Therapeutic Horizon: HPV Vaccines and Their Impact on Cutaneous Diseases-A Comprehensive Review

Human papillomavirus (HPV) encompasses a diverse array of viruses, comprising approximately 200 serotypes that affect humans. While the majority of HPV strains are associated with benign skin or mucous membrane growths, a subset is implicated in severe health conditions, such as cervical, anal, vulvar, and vaginal cancers. Despite the established effectiveness of HPV vaccines in preventing cervical and anal carcinomas in particular, their therapeutic potential in addressing cutaneous diseases linked to diverse HPV strains remains an intriguing area of investigation. This narrative review critically examines the existing literature to assess the viability of HPV immunization as a therapeutic intervention for prevalent cutaneous conditions. These include genital and extragenital cutaneous warts, epidermodysplasia verruciformis, and keratinocyte carcinomas. The findings suggest a promising dual role for HPV vaccines in preventing and treating dermatologic conditions while emphasizing future research directions, including the immunization perspective against β-HPVs. Moreover, the presence of conflicting study outcomes underscores the imperative for larger-scale, randomized trials with well-matched control groups to validate the efficacy of HPV immunization in the dermatologic context. This review contributes valuable insights into the evolving landscape of HPV-vaccine applications in the field of dermatology.

Intralesional human papillomavirus vaccine for the treatment of recalcitrant cutaneous warts

Human papillomavirus (HPV) is ubiquitously distributed in the population worldwide and its most frequent clinical presentation is cutaneous warts. Despite various treatment options currently available, many patients experience persistent and refractory disease. We sought to evaluate the clinical effectiveness and safety profile of intralesional HPV 9-valent vaccine for the treatment of recalcitrant warts. A retrospective study was performed for all cases of cutaneous warts treated with intralesional 9-valent HPV vaccine between January 2017 and March 2021. Epidemiologic, clinical, and treatment data, including safety and effectiveness scores, were reviewed. Our cohort was composed of 20 patients: 13 adults and seven children. Twelve patients (60%) displayed a complete response whereas 8 patients (40%) showed a partial response. Older age was associated with a better response to treatment, while a history of laser therapy was associated with a worse prognosis. Adverse events were local, transient, and negligible. No systemic adverse effects were reported. Intralesional 9-valent HPV vaccine may be considered for the treatment of recalcitrant cutaneous warts. Controlled studies are required to confirm these results.

Intralesional combined furosemide and digoxin in cutaneous warts treatment: A randomized controlled clinical trial

Although being a benign lesion, Warts can affect the quality of life by causing discomfort, disfigurement, and social embarrassment besides the tendency to spread. Cutaneous wart treatment faces many challenges as the development of an antiviral drug that can eradicate the human papilloma virus (HPV) is difficult. This clinical study aimed to assess the efficacy and safety of intralesional combined furosemide and digoxin in the treatment of multiple cutaneous warts. This double blinded randomized clinical trial included 80 adult patients with multiple cutaneous warts (≥2 warts) who were randomized into two groups, Group I (40 patients) treated with intralesional combined furosemide and digoxin and Group II (40 patients) who were treated with intralesional normal saline solution as a control group, weekly till improvement or for maximum five sessions. Clinical and dermoscopic evaluation at baseline, every session, and monthly for 6 months after the last session to detect any recurrence was performed. Complete wart clearance was observed in 92.5% of patients in the intralesional combined furosemide and digoxin group (Group I) compared with 10.0% in saline group (Group II), with highly statistically significant difference (P-value = 0.000). Pain during injection in 95.0% and 45.0% of patients in Group I and Group II respectively, treatment group was superior compared to control group. Intralesional injection of combined furosemide and digoxin can be a safe and effective treatment option in multiple cutaneous warts with minimal side effects in this study.

Intralesional Versus Intramuscular Hepatitis B Virus Vaccine in the Treatment of Multiple Common Warts

BACKGROUND

Hepatitis B virus (HBV) vaccination is associated with stimulation of humoral and cell-mediated immunity. Intralesional HBV vaccine has been recently used as an immunotherapy of common warts with relatively low success rate.

AIM

To assess the efficacy and safety of intralesional versus intramuscular (IM) HBV vaccine in the treatment of multiple common warts.

PATIENTS AND METHODS

The study included 60 patients with multiple common warts who were randomly assigned to 2 groups: intralesional HBV vaccine or IM HBV vaccine. In the intralesional HBV vaccine group, the vaccine was injected into the largest wart at 2-week intervals until complete clearance or for a maximum of 5 sessions. Intramuscular HBV vaccine group received 3 injections in the deltoid muscle at 0, 1, and 6 months.

RESULTS

Complete wart clearance was reported in 7 patients (23.3%) of the intralesional HBV vaccine group and 15 patients (50%) of the IM HBV vaccine group. The difference was statistically significant in favor of the IM group ( p = .0479). Adverse effects were mild and insignificant in the 2 groups.

CONCLUSION

HBV vaccine, particularly the IM form seems to be a promising, well-tolerated therapeutic option for the treatment of warts.

LIMITATIONS

Short follow-up period and small sample size.
