Treatment of Recalcitrant Viral Warts with Combination Therapy of Systemic Acitretin and Diphenylcyclopropenone Immunotherapy

Suppression of Interferon Response and Antiviral Strategies of Bunyaviruses

The order Bunyavirales belongs to the class of Ellioviricetes and is classified into fourteen families. Some species of the order Bunyavirales pose potential threats to human health. The continuously increasing research reveals that various viruses within this order achieve immune evasion in the host through suppressing interferon (IFN) response. As the types and nodes of the interferon response pathway are continually updated or enriched, the IFN suppression mechanisms and target points of different virus species within this order are also constantly enriched and exhibit variations. For instance, Puumala virus (PUUV) and Tula virus (TULV) can inhibit IFN response through their functional NSs inhibiting downstream factor IRF3 activity. Nevertheless, the IFN suppression mechanisms of Dabie bandavirus (DBV) and Guertu virus (GTV) are mostly mediated by viral inclusion bodies (IBs) or filamentous structures (FSs). Currently, there are no effective drugs against several viruses belonging to this order that pose significant threats to society and human health. While the discovery, development, and application of antiviral drugs constitute a lengthy process, our focus on key targets in the IFN response suppression process of the virus leads to potential antiviral strategies, which provide references for both basic research and practical applications.

Effectiveness and safety of topical application of diphenylcyclopropenone versus podophyllin in treatment of genital warts

BACKGROUND

Many therapeutic modalities are available for treating genital warts; however, the effectiveness of both diphenylcyclopropenone and podophyllin is still controversial.

AIM

To evaluate the effectiveness and safety of diphenylcyclopropenone and podophyllin in treating genital warts.

METHODS

This study included 57 patients, divided randomly into two groups. Group (A): diphenylcyclopropenone (n = 29). Group (B): podophyllin 25% (n = 28). In group (A), sensitization was done with 2% diphenylcyclopropenone. Then, after 1 or 2 weeks, treatment started with a weekly application of diphenylcyclopropenone solutions ranging between 0.001 and 1% until clearance, or for a maximum of 10 sessions. In group (B), podophyllin 25% was applied weekly until clearance or for a maximum of 6 weeks.

RESULTS

Higher clearance was achieved in group A, with 19 of 29 (65.5%) patients, than in group B, with 9 of 28 (32.1%) (p-value = 0.004). Also, effectiveness increases with young age in group A. Shorter wart duration was associated with better response in both groups (p-value = 0.005). No serious adverse effects occurred in either group. No recurrence was detected in group A, while seven patients (77.8%) had recurrence in group B after 1 year of follow up.

CONCLUSION

Diphenylcyclopropenone shows a higher success rate than podophyllin in treating genital warts and a lower recurrence rate.

Systemic immunotherapy for the treatment of warts: A literature review

BACKGROUND

Immunotherapy has emerged as a critical therapeutic tool for the treatment of warts. Immunotherapy for warts is currently restricted to recalcitrant lesions. A small number of regimens appear to be extremely effective. Furthermore, there is a scarcity of evidence-based research.

OBJECTIVE

Furthermore, in the majority of cases, their safety and effectiveness have not been evaluated in double-blind, controlled clinical trials, making the reproducibility of many of the listed treatments difficult to analyze and a possible placebo effect difficult to rule out.

METHODS

Analyzing and discussing different types of systemic immunotherapy. The different types of immunotherapy for warts are mentioned in this report.

RESULTS

Systemic immunotherapeutic modalities commonly used in the treatment Echinacea, propolis, oral retinoids, glycyrrhizinic acid, levamisole, cimetidine, and zinc sulfate have all been reported as effective treatment modalities for different types of warts.

CONCLUSION

Immunotherapy has emerged as one of the most important therapeutic modalities for warts. Such treatment is required not only for recalcitrant or multiple lesions, but also in the majority of treated cases.
