RESUMEN
BACKGROUND: The clinical strategy of oral supplementation of Vitamin D (VD) as a preventive and therapeutic measure for warts needs further exploration. METHODS: The clinical data of patients with skin diseases who visited the Children's Hospital affiliated with Chongqing Medical University from February 2018 to June 2024 were collected. The serum VD levels in patients with warts (common warts, flat warts, and plantar warts) and patients with other common skin diseases (atopic dermatitis, psoriasis, alopecia areata, vitiligo, and chronic urticaria) were compared. Two-sample bidirectional Mendelian randomization (MR) analysis was performed to investigate potential causal associations between VD and warts. RESULTS: The average serum VD level of children with warts was 23.27 ± 7.07 ng/mL, which showed no statistically significant difference compared to children with other common skin diseases. The inverse variance weighted (IVW) method analysis indicated a positive causal relationship between VD and warts (Odds Ratio [OR] = 1.86, [95% CI: 1.19-2.92], p = 0.007). Sensitivity analysis did not show any indication of horizontal pleiotropy or heterogeneity. The MR-PRESSO method did not identify any outliers. CONCLUSION: The levels of serum VD in children with warts do not significantly decrease compared to children with other common skin conditions. The evidence from the MR analysis indicates a positive causal relationship between VD and warts, suggesting caution in supplementing VD for children with warts who have normal or elevated serum VD levels. Further clinical studies are needed for validation in the future.

Human papillomaviruses (HPVs) are etiologically associated with various benign and malignant neoplasms of cutaneous and mucosal epithelia. We describe an improved diagnostic protocol for comprehensive characterization of causative HPV types in common warts, in which broad-spectrum PCRs followed by Sanger sequencing, two previously described and seven newly developed type-specific quantitative real-time PCRs (qPCRs) coupled with the human beta-globin qPCR were used for: (i) diagnosis of HPV infection in warts; (ii) estimation of cellular viral loads of all HPV types detected; and (iii) determination of their etiological role in 128 histologically confirmed fresh-frozen common wart tissue samples. A total of 12 different causative HPV types were determined in 122/126 (96.8%) HPV-positive warts, with HPV27 being most prevalent (27.0%), followed by HPV57 (26.2%), HPV4 (15.1%), HPV2 (13.5%), and HPV65 (7.9%). The cellular viral loads of HPV4 and HPV65 were estimated for the first time in common warts and were significantly higher than the viral loads of HPV2, HPV27, and HPV57. In addition, we showed for the first time that HPV65 is etiologically associated with the development of common warts in significantly older patients than HPV27 and HPV57, whereas HPV4-induced warts were significantly smaller than warts caused by HPV2, HPV27, HPV57, and HPV65.

BACKGROUND: Management of multiple recalcitrant common warts represents a therapeutic challenge. Both oral isotretinoin and acitretin have shown a promising efficacy in the treatment of various types of warts. However, a comparative study of the two medicines in wart treatment has not yet been conducted. OBJECTIVE: The aim of this study was to assess the efficacy and adverse effects of oral isotretinoin versus acitretin in the treatment of multiple recalcitrant common warts. METHODS: This study was conducted on 75 adult male patients with recalcitrant multiple common warts. The patients were randomly assigned to three groups: group 1 (30 patients) received oral isotretinoin, group 2 (30 patients) received acitretin, and group 3 received oral placebo (15 patients). The treatment was given daily until complete clearance or for a maximum of 3 months. RESULTS: Complete clearance of the treated lesions was observed in 18 patients (60%) of the isotretinoin group, in 22 patients (73.3%) of the acitretin group, and in 0 patients (0%) of the placebo group. A statistically significant difference was observed in the therapeutic response between the treatment groups, and the placebo group was observed. Adverse effects of the used drugs were mild and transient. CONCLUSION: Oral isotretinoin and acitretin are promising effective modalities with minimal side effects for the treatment male patients with multiple recalcitrant common warts with a relative superiority of acitretin.

Introduction: Verruca vulgaris is a benign hyperkeratotic proliferation of the epidermis. Few studies look at the differences in serum and tissue macrophage migration inhibitory factor (MIF) levels in verruca vulgaris, as well as its gene polymorphisms that have yet to be explored. The current study provided in-depth evaluation of MIF in serum and tissues of patients with verruca vulgaris, and establishes for the first time the possible association of MIF gene polymorphisms with common warts. Methods: This case-control study included 50 patients who were diagnosed clinically as common warts in comparison with 50 age and sex-matched controls. Clinical examination was done on all included cases. Serum MIF was measured using enzyme-linked immunosorbent assay (ELISA), while its tissue expression was analyzed using Western blotting and immunohistochemical techniques for the included participants. Analysis of MIF-173 GËC single nucleotide polymorphism was performed by polymerase chain reaction (PCR) using restriction fragment length polymorphism (RFLP) technique. Results: The overall results revealed significantly lower MIF tissue expression in lesional and perilesional skin biopsies from cases compared to the controls using Western blot and immunohistochemical analysis. Yet, the difference in the serum MIF levels between cases and controls was not significant (p Ë 0.05). GC genotype of the studied MIF rs755622 G>C SNP could be considered as a protective genetic factor against the occurrence of verruca vulgaris among Egyptians with OR (95% CI) equal 0.444 (0.199-0.989). Conclusion: MIF and its genetic variants are thought to play a pathogenic role in verruca vulgaris development and recurrence.
RESUMEN
Different modalities are used for treatment of common warts, but none of them had been proved the best in achieving complete cure. We aim to compare the effect of cryotherapy, intralesional injection of tuberculin purified protein derivative (PPD) and cryotherapy combined with intralesional injection of tuberculin PPD in the treatment of multiple common warts. This study is a randomized clinical trial in which the patients were randomly divided into three groups; group (A) included 25 patients subjected to cryotherapy, group (B) included 25 patients subjected to intralesional injection of tuberculin PPD and group (C) included 25 patients subjected to cryotherapy plus intralesional injection of tuberculin PPD. All the three groups showed a significant clinical improvement (p < 0.001) with statistically significant difference between cryotherapy group (A) and intralesional injection of tuberculin PPD group (B) (p < 0.001) and between cryotherapy group (A) and cryotherapy plus intralesional injection of tuberculin PPD group (C) (p < 0.001). However, there was no statistically significant difference between both intralesional injection of tuberculin PPD group alone (B) and cryotherapy plus intralesional injection of tuberculin PPD group (C) (p = 0.213). In Conclusion the cryotherapy combined with intralesional injection of PPD and intralesional injection of PPD alone are better than cryotherapy alone in treatment of multiple common warts. However, better response could be reached in combination of both cryotherapy and intralesional PPD with less number of sessions.

INTRODUCTION: Verrucae vulgaris, or common warts, is a common skin condition for which there is no US Food and Drug Administration-approved treatment. Compounded cantharidin has been used to treat warts for years but lacks a controlled formulation, consistent application schedule and methods, and robust safety and efficacy studies. VP-102 is a proprietary drug-device combination product containing a topical formulation of 0.7% (w/v) cantharidin in a single-use delivery device. This objective of the phase 2 study was to evaluate the efficacy, safety, tolerability, and optimal regimen of VP-102 in the treatment of common warts. METHODS: In this open-label trial, participants aged ≥ 2 years with one to six common warts were administered VP-102 topically to treatable common warts once every 14 days (Cohort 1) or once every 21 days in conjunction with paring (Cohort 2), for up to four treatments. Participants were evaluated through to day 84 (Cohort 1) or day 147 (Cohort 2). The primary endpoint was the percentage of participants with complete clearance of all treatable common warts (baseline and new) at day 84. Secondary endpoints included percentage of participants achieving complete clearance of all treatable common warts at other visits. Safety assessments included treatment-emergent adverse events (TEAEs), including local skin reactions (LSRs). RESULTS: A total of 21 and 35 participants were enrolled in Cohort 1 and Cohort 2, respectively. Complete clearance at day 84 was seen in 19.0% of participants in Cohort 1 and 51.4% of those in Cohort 2. The most common TEAEs were expected LSRs and included application site vesicles, pain, pruritus, erythema, and scab. Most LSRs were mild or moderate in severity. CONCLUSION: VP-102 showed efficacy in complete clearance of common warts from baseline to day 84, as well as at follow-up visits. Due to the higher percentage of patients exhibiting complete clearance in Cohort 2, the treatment regimen of Cohort 2 will be pursued in future studies. TEAEs were expected due to the pharmacodynamic action of cantharidin, a vesicant. Clinical Trials ID: NCT03487549.
RESUMEN
Human papillomavirus (HPV)-induced cutaneous disease is a common complaint for patients presenting for dermatology evaluation. Infection by HPV is the major etiologic factor in the development of cutaneous warts, epidermodysplasia verruciformis, and possibly a subset of cutaneous squamous cell carcinoma. Carcinoma of the genitourinary tract, most notably cervical carcinoma, is the most severe manifestation of infection with specific serotypes of HPV. For this reason, the HPV immunization (Gardasil) was developed in 2006 and upgraded in 2018 to a nonavalent formulation that includes serotypes 6, 11, 16, 18, 31, 33, 45, 52, 58. While immunization is highly effective at preventing infection with serotypes included in the formulation, it is less clear if the immunization can aid in managing active HPV infection. This review examines the available literature regarding the role of HPV immunization in managing common warts, genital warts, keratinocyte carcinoma, and epidermodysplasia verruciformis.

BACKGROUND: Garlic (Allium sativum L.) is a common herb consumed worldwide as functional food and traditional remedy for the prevention of infectious diseases since ancient time. Garlic and its active organosulfur compounds (OSCs) have been reported to alleviate a number of viral infections in pre-clinical and clinical investigations. However, so far no systematic review on its antiviral effects and the underlying molecular mechanisms exists. SCOPE AND APPROACH: The aim of this review is to systematically summarize pre-clinical and clinical investigations on antiviral effects of garlic and its OSCs as well as to further analyse recent findings on the mechanisms that underpin these antiviral actions. PubMed, Cochrane library, Google Scholar and Science Direct databases were searched and articles up to June 2020 were included in this review. KEY FINDINGS AND CONCLUSIONS: Pre-clinical data demonstrated that garlic and its OSCs have potential antiviral activity against different human, animal and plant pathogenic viruses through blocking viral entry into host cells, inhibiting viral RNA polymerase, reverse transcriptase, DNA synthesis and immediate-early gene 1(IEG1) transcription, as well as through downregulating the extracellular-signal-regulated kinase (ERK)/mitogen activated protein kinase (MAPK) signaling pathway. The alleviation of viral infection was also shown to link with immunomodulatory effects of garlic and its OSCs. Clinical studies further demonstrated a prophylactic effect of garlic in the prevention of widespread viral infections in humans through enhancing the immune response. This review highlights that garlic possesses significant antiviral activity and can be used prophylactically in the prevention of viral infections.
RESUMEN
INTRODUCTION: Common warts are one of the most prevalent infections affecting the skin. Common warts are caused by human papillomaviruses (HPV), which are ubiquitous in our environment. Most HPV infections are directly controlled and cleared by host immune system, although each case has the potential to persist and transform into a recalcitrant form. It is not exactly clear why certain populations are more susceptible to common warts. AIM: To investigate factors affecting the occurence and outcome of common warts. MATERIAL AND METHODS: A total of 188 consecutive patients with common warts (106 men, 82 women) and 188 controls were prospectively enrolled. Demographic and clinical characteristics were recorded. The Chi-square, Mann-Whitney U and Kruskal-Wallis tests were used for statistical analysis, with a significance threshold of p<0.05. RESULTS: There were not any significant associations between cigarette smoking, alcohol consumption, accompanying diseases, medications, family history of warts and the duration of warts (p=0.102, p=0.317, p=0.535, p=0.535, p=0.535, respectively). There were not any significant associations between cigarette smoking, alcohol consumption, accompanying diseases, medications, family history of warts and the number of warts (p=0.232, p=0.762, p=0.389, p=0.389, p=0.824, respectively). CONCLUSIONS: Our study has revealed that smoking is not a risk factor for common warts. However, we suspect the lack of statistical differences are likely due to small sample size of the study. Further studies with larger sample sizes are needed.
RESUMEN
BACKGROUND: Common warts rarely occur on the nasal vestibule. It should be treated more carefully than other skin lesions because scar contracture results in the narrowing of the external naris, causing nasal obstruction and reducing the patient's quality of life. In this report, we introduce our method for common warts on the nasal vestibule using handheld cryoablation devise. PATIENTS AND OPERATIVE METHODS: We performed a series of four cryosurgical ablation procedures to treat common warts on the nasal vestibule. All the procedures employed a reusable handheld cryoablation device (CRY-AC®, Brymill Cryogenic Systems, Ellington, CT). RESULT: All patients were successfully treated for four to six sessions without any adverse event. CONCLUSION: Cryotherapy for common warts on nasal vestibular is easily performed in an office setting under no anesthesia without bleeding. We believe this easy and safe procedure is suitable as the first line therapy for common wart on nasal vestibular.

Background: Assessment of human papillomavirus (HPV) type-specific viral load (VL) is a valid tool for determining the etiology of HPV-related skin tumors, especially when more than one HPV type is detected within one lesion. Methods: The causative HPV type was determined in 185 fresh-frozen tissue specimens of histologically confirmed common warts (CWs) collected from 121 immunocompetent patients. All tissues were tested using the type-specific quantitative real-time polymerase chain reactions (PCR) for the most common wart-associated Alpha-PV (HPV2/27/57) and Mu-PV types (HPV1/63/204). The presence of 23 additional low-risk HPVs was evaluated using a conventional wide-spectrum PCR. Results: HPV DNA was detected in 176/185 (95.1%) CWs and multiple HPV types in 71/185 (38.4%) lesions. Using the VL approach and a robust cutoff of one viral copy/cell established in this study, HPV2/27/57 were determined as causative agents in 41/53 (77.3%) and 53/71 (74.7%) CWs with single and multiple HPVs, respectively. Conclusions: CWs are mostly etiologically associated with HPV2/27/57 and only rarely with HPV1. In the majority of CWs containing multiple HPVs, a single HPV type was present in high concentration, indicating etiological association. No significant differences in VLs of lesion-causing HPV types in CWs containing single or multiple HPVs were found.

BACKGROUND: Common warts are caused by human papillomaviruses (HPVs), they are among the most common cutaneous viral infections. Macrophage migration inhibitory factor (MIF) is an essential contributor in many inflammatory and immune skin diseases. Yet, its role in the pathology of common warts is unclear. OBJECTIVE: To assess MIF levels in lesional and perilesional skin in patients with common warts in comparison to apparently healthy control group with matching age and sex. SUBJECTS AND METHODS: A case-control study performed on 60 patients with common warts (group A) and 30 age and sex matching healthy controls (group B). Two biopsies were taken from each patient in group A; one from the lesion (lesional) and the other one from the skin around the wart (perilesional), while biopsies of controls were taken from matched sites to patients. Measurement of MIF in all groups was done by quantitative ELISA kits. RESULTS: Significant high MIF levels were detected in lesional and perilesional skin biopsies compared to controls (P<0.001). Yet, the difference in MIF levels between lesional and perilesional skin biopsy was non-significant. No significant relations were found between lesional and perilesional MIF levels and clinical characteristics of the studied patients while both lesional and perilesional MIF levels were significantly correlated (rh=0.269, P=0.021). CONCLUSION: The significantly elevated MIF levels in lesional and perilesional skin biopsies compared to controls point to its role in wart progression from HPV infected cells.
RESUMEN
Background: There are limited number of topical agents for the treatment of common warts. Few reports show efficacy of zinc oxide for such indication. Objectives: We sought to evaluate the efficacy of topical 15% zinc oxide ointment for the reduction in size of common warts. Materials and Methods: Sixteen patients with two comparable palmar warts or verruca vulgaris were randomized to receive either 15% zinc oxide ointment or placebo three times a day for four weeks. Diameter, surface area, and volume change of warts in both groups were used as objective assessments, while patient and physician assessments were also recorded. Results: At Week 4, zinc oxide significantly reduced the median surface area compared to baseline (P<0.037). However, when the median percent changes between groups were compared, there were no statistically significant differences. Conclusions: Zinc oxide can reduce the size of common hand warts after four weeks. We suggest that it can be used as an adjunctive therapy to enhance the efficacy of other treatments.
RESUMEN
RESUMEN Las verrugas vulgares son proliferaciones benignas producidas por el HPV (virus del papiloma humano) que afectan al 7-10 % de la población en general. Cuando se localizan en la planta del pie generan intenso dolor, interfiriendo en la vida diaria del paciente, y su erradicación suele ser dificultosa. Existen múltiples tratamientos; ninguno es efectivo en su totalidad. La bleomicina es una opción terapéutica en aquellos casos rebeldes y recidivantes.
SUMMARY Common warts are benign proliferations caused by HPV (papilloma virus).When these are in foot generate an intense pain that interferes with daily life of the patient and are difficult to eradicate. There are multiple treatments, none is completely effective. Bleomycin is a therapeutic option for those rebels and recurrent cases.
RESUMEN
INTRODUCTION: Common warts are hyperkeratotic, benign cutaneous growths caused by types 1, 2, and 7 Human papilloma viruses. Different modalities are available to treat warts. Cryotherapy is one of the most common and effective treatments for common warts. Trichloroacetic acid (TCA), in high concentrations, can be used as a therapeutic modality. OBJECTIVES: The aim of this study is to compare the efficacy and safety of cryotherapy using liquid nitrogen (spray method) versus trichloroacetic acid 90% in treatment of common warts. PATIENTS AND METHODS: Thirty-five patients with 414 common warts, from the Dermatology outpatient clinic, Assiut University Hospital, were enrolled in this study. We used two techniques for the treatment of common warts. The lesions in each patient were divided into two groups (A and B), group A treated by cryotherapy while group B treated by trichloroacetic acid (TCA) 90%. RESULTS: There was significant decrease in the size of the warts in both groups. There were statistically significant better results among group A than group B regarding the mean percentage of improvement (90.11 ± 27.92 vs 26.19 ± 42.93, respectively; P < 0.001) and grade of improvement, where good response was obtained in 89.2% in group A compared with 26.2% in group B (P < 0.001). Complete cure was significantly higher in group A (83.1%) than group B (21.3%; P < 0.001). However, side effects were significantly higher among group A than group B. CONCLUSION: Cryotherapy is more effective than TCA 90% in treatment of common wart. TCA 90% has lesser complications than cryotherapy.

RESUMEN
BACKGROUND: Common warts are skin diseases caused by human papillomavirus. Several treatment modalities available for common warts, two of them are electrodesiccation with curettage and application of 80% phenol solution. AIM: This study aims to compare clinical efficacy between these two modalities. MATERIAL AND METHODS: Open clinical trial was conducted at Dr Pirngadi General Hospital Medan and H. Adam Malik General Hospital Medan from February to June 2013 on 17 patients with multiple common warts. Both treatments began and applied simultaneously on the same day on each patient. RESULTS: Cure rate was higher in electrodesiccation with curettage (76.5%, 100%) compared to the application of 80% phenol solution (11.8%, 64.7%) on three weeks and six weeks of follow up. Statistical analysis showed a significant difference of common warts cure rate between electrodesiccation with curettage and application of 80% phenol solution after three weeks (p < 0.001) and six weeks (p = 0.018) of treatment. CONCLUSION: As a conclusion, electrodesiccation with curettage has higher cure rate than the application of 80% phenol solution on the treatment of common warts. Further study is needed to find out the best concentration and time interval for application of phenol solution to improve its clinical efficacy as an alternative treatment of choice for common warts.
