Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Plantar warts are benign skin lesions caused by human papillomavirus (HPV).There are several treatment methods for this illness, but none of them can heal all patients. Cryotherapy using liquid nitrogen is one of the most common local treatments. In this study, we will compare the effectiveness of cryotherapy with liquid nitrogen with the association of organic acids and nitric acid (nitric-zinc complex). In addition, as secondary objectives have been defined: 1) know the number of applications necessary for each treatment to achieve the complete resolution of the plantar wart, in order to compare the healing times between each treatment and establish which treatment is faster, 2) analyze the influence of the HPV biotype, the location of the lesion and the time of evolution in the response to the different treatments, and 3) Compare the ultrasound signs of plantar warts with the ultrasound signs of healthy skin after the resolution of the process.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A randomized controlled clinical trial is proposed. The recruitment of patients will be carried out by including the sample of those patients who have diagnostic confirmation of plantar wart in the Chiropodology and Surgery Service of the University Podiatry Clinic of the Complutense University of Madrid, consecutively, between November 2020 and the date when the estimated sample size is reached.

Participants in the trial will be assigned with equal probability to each treatment arm, based on their consecutive inclusion in the study. Subsequently, the treatment allocation will be determined by a random code generated by the Epidat 4.1 program using random permuted blocks. The treatment used will be evident both for the participant and for the research podiatrist responsible for the intervention. However, the primary result will be confirmed by the microbiological study carried out by the Department of Microbiology of the Complutense University of Madrid, which does not know any data about the patient or the treatment group to which it was initially assigned.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cryoteraphy with liquid nitrogen

Patients older than 18 years with a diagnosis of plantar wart, who have agreed to participate in the study.

Group Type EXPERIMENTAL

Cryoteraphy with liquid nitrogen

Intervention Type PROCEDURE

Weekly, at each visit, before applying the treatment, a debridement of the hyperkeratotic tissue covering the wart will be performed with a scalpel handle of number 3 and a scalpel blade of number 15, and then the treatment will be applied.

Subsequently, the application of cryotherapy with liquid nitrogen will be carried out using CryoPen b® (HO Equipment, Hhislenghien-Belgium). To analyze the homogeneous application in all the patients in the study, perform 2 applications of 15 seconds per session, with an interval of 30 seconds between each application, such and as manufacturers recommend. The number of sessions in which the product is applied will be a maximum of 5, following the procedure of previous studies.

Nitric-zinc complex

Patients older than 18 years with a diagnosis of plantar wart, who have agreed to participate in the study.

Group Type EXPERIMENTAL

Nitric-zinc complex

Intervention Type PROCEDURE

Weekly, at each visit, before applying the treatment, a debridement of the hyperkeratotic tissue covering the wart will be performed with a scalpel handle of number 3 and a scalpel blade of number 15, and then the treatment will be applied.

Subsequently, the application of nitric acid-zinc complex with Verrutop® (Isdin, Barcelona-Spain) will be carried out. The preparation is applied by making small touches with the applicators included in the product.

The number of sessions in which the product is applied will be a maximum of 5, following the recommendations of the manufacturers in the product data sheet.
