Cantharidin-Podophyllin-Salicylic Acid Formulation as a First-Line Treatment for Plantar Warts? A Case Report with Multiple Plantar Warts of Human Papillomavirus Biotype 27 and Previous Failed Treatments.

Project description:BACKGROUND Plantar warts are benign skin tumors caused by the human papillomavirus (HPV). There are multiple treatments, but none ensure absolute success. Successful treatment depends on several factors, such as the location, number of lesions, HPV biotype, and the patient's health condition. This report presents a 53-year-old woman who had multiple recalcitrant plantar warts with HPV biotype 27 that were treated using a cantharidin-podophyllin-salicylic acid (CPS) formulation after 2 failed treatments. CASE REPORT A 53-year-old woman was seen on October 25, 2021. She had 6 plantar warts due to HPV biotype 27, which was confirmed by polymerase chain reaction using a sample of hyperkeratosis scales obtained from the wart after debridement. Five cryotherapy sessions were applied, without clinical improvement. Two sessions of nitric-acid-zinc complex were then applied, from which the patient reported severe pain, without clinical improvement. Finally, 3 sessions of CPS formulation were applied, and the HPV remitted in all warts. CONCLUSIONS Conservative treatments, such as cryotherapy, have not been effective in a case of multiple recalcitrant plantar warts. The combined action of the 3 compounds of CPS formulation was key in the resolution of this case. Plantar wart treatment should be easy to apply, effective, fast, and efficient. In cases of recalcitrant or numerous warts, treatment should be more aggressive from the beginning if the patient's lifestyle allows it. It would be interesting to conduct randomized clinical trials to find out which patients could be indicated for the CPS formulation as a first line of treatment.

Cryotherapy with liquid nitrogen versus topical salicylic acid application for cutaneous warts in primary care: randomized controlled trial.

Project description:BackgroundCryotherapy is widely used for the treatment of cutaneous warts in primary care. However, evidence favours salicylic acid application. We compared the effectiveness of these treatments as well as a wait-and-see approach.MethodsConsecutive patients with new cutaneous warts were recruited in 30 primary care practices in the Netherlands between May 1, 2006, and Jan. 26, 2007. We randomly allocated eligible patients to one of three groups: cryotherapy with liquid nitrogen every two weeks, self-application of salicylic acid daily or a wait-and-see approach. The primary outcome was the proportion of participants whose warts were all cured at 13 weeks. Analysis was on an intention-to-treat basis. Secondary outcomes included treatment adherence, side effects and treatment satisfaction. Research nurses assessed outcomes during home visits at 4, 13 and 26 weeks.ResultsOf the 250 participants (age 4 to 79 years), 240 were included in the analysis at 13 weeks (loss to follow-up 4%). Cure rates were 39% (95% confidence interval [CI] 29%-51%) in the cryotherapy group, 24% (95% CI 16%-35%) in the salicylic acid group and 16% (95% CI 9.5%-25%) in the wait-and-see group. Differences in effectiveness were most pronounced among participants with common warts (n = 116): cure rates were 49% (95% CI 34%-64%) in the cryotherapy group, 15% (95% CI 7%-30%) in the salicylic acid group and 8% (95% CI 3%-21%) in the wait-and-see group. Cure rates among the participants with plantar warts (n = 124) did not differ significantly between treatment groups.InterpretationFor common warts, cryotherapy was the most effective therapy in primary care. For plantar warts, we found no clinically relevant difference in effectiveness between cryotherapy, topical application of salicylic acid or a wait-and-see approach after 13 weeks.

Topical pyruvic acid (70%) versus topical salicylic acid (16.7%) compound in treatment of plantar warts: A randomized controlled trial.

Project description:BackgroundRecurrence rate is considerable with current topical treatments of plantar warts. We compared the efficacy of topical pyruvic acid (70%) with salicylic acid (16.7%) compound in treating multiple plantar warts.Materials and methodsIn this randomized controlled trial, 60 patients with multiple plantar warts were equally randomized to receive either pyruvic acid 70% or compound salicylic acid solution (salicylic acid 16.7%, lactic acid 16.7%, and collodion 100%) that was topically applied twice a day for 4 weeks. Patients were visited every 2 weeks for 1 month after starting treatment and then every 1 month for another 2 months. The number and size of warts, treatment complications (pain, burning, scar, pigmentation, and crust), and recurrence were evaluated.ResultsWarts' number was decreased by -13.12 ± 25.6% with pyruvic acid and by -23.0 ± 28.0% with compound salicylic acid (P = 0.159) after treatment. Warts' size was decreased by -43.47 ± 57.0% with pyruvic acid and by -37.40 ± 32.76% with compound salicylic acid (P = 0.615) after treatment. There was no difference between the two groups in cumulative incidence of treatment complications (P > 0.05). Also, there was no difference between the two groups in recurrence rate at 2 months (10 vs. 16.7%, P = 0.500) or at 3 months after treatment (3.3 vs. 6.7%, P = 0.335).ConclusionTopical pyruvic acid and compound salicylic acid had the same efficacy and complications in treating plantar warts. Decision for choosing the treatment can be made based on the costs and individual factors as well as patients preferences.

Safety and Efficacy of Nano-Pulse Stimulation Treatment of Non-Genital, Cutaneous Warts (Verrucae).

Project description:Background and objectivesThis study describes the effects of nano-pulse stimulation (NPS) technology on the common verruca with the objectives of demonstrating efficacy and safety. NPS technology applies nanosecond pulses of non-thermal electrical energy to induce highly localized regulated cell death in the cellular structures of the targeted zone with negligible effects on surrounding non-cellular structures. Previous clinical studies applying NPS to common, benign skin lesions have demonstrated safety and efficacy in clearing seborrheic keratoses and sebaceous hyperplasia.Study design/materials and methodsSixty-two subjects were enrolled at a total of five sites. One hundred and ninety-five study verrucae up to 10 mm wide were treated with NPS delivered by a console-based handheld applicator (CellFX® System; Pulse Biosciences) and follow-ups occurred every 30 days with the option to retreat at 30, 60, and 90 days. There were 62 untreated controls and 46% of the treated verrucae were recalcitrant.ResultsOverall, 75.3% (70/93) of the common verrucae, 72.7% (8/11) of the flat verrucae, and 43.8% (14/32) of the plantar verrucae treated with NPS were completely clear by 60 days following the last treatment and did not recur within the 120-day observation period. The majority (54%) of verrucae cleared with a single NPS procedure. The most common treatment site reactions were erythema (50.5%) and eschar formation (23.4%) on Day 30 and on Day 120 mild erythema was present in 14% of the cases and hyperpigmentation in 18.5%. No serious adverse events were reported. A particle counter was used during 11 NPS procedures on verrucae and no significant plume generation was detected during these procedures.ConclusionsNPS is a safe and effective procedure for removing non-genital, cutaneous verrucae.

An optimized method for Oil Red O staining with the salicylic acid ethanol solution.

Project description:Oil Red O (ORO) staining is a commonly used experimental technique to detect lipid content in cells or tissues. Freshly prepared ORO in 60% isopropanol is the most widely used method at present. However, isopropanol is volatile and harmful to the human body. It will also affect the interpretation of the results due to the formation of crystals and non-specific diffuse staining. In this paper, by screening and validation, we report a salicylic acid ethanol solution (containing 50% ethanol, 5%-10% salicylic acid) for the preparation of ORO solution, which has a better staining effect on lipid staining in cells and tissues, with a clean background and short dyeing time. What's more, this ORO solution is non-toxic, convenient to prepare, and can be stored for a long time. Therefore, it is reliable, easy to operate, and can be widely popularized and applied in laboratories.

Genome-wide identification of methylated CpG sites in nongenital cutaneous warts.

Project description:BackgroundLow-risk HPV infection has not been the subject of epigenetic investigation. The present study was carried out in order to investigate the methylation status of CpG sites in non-genital cutaneous warts.MethodsGenomic DNA was extracted from 24 paired epidermal samples of warts and normal skin. DNA samples were bisulfite converted and underwent genome-wide methylation profiling using the Infinium MethylationEPIC BeadChip Kit.ResultsFrom a total of 844,234 CpG sites, 56,960 and 43,040 CpG sites were found to be hypo- and hypermethylated, respectively, in non-genital cutaneous warts. The most differentially methylated CpG sites in warts were located within the C10orf26, FAM83H-AS1, ZNF644, LINC00702, GSAP, STAT5A, HDAC4, NCALD, and EXOC4 genes.ConclusionNon-genital cutaneous warts exhibit a unique CpG methylation signature.

Salicylic Acid Binding Proteins (SABPs): The Hidden Forefront of Salicylic Acid Signalling.

Project description:Salicylic acid (SA) is a phytohormone that plays important roles in many aspects of plant life, notably in plant defenses against pathogens. Key mechanisms of SA signal transduction pathways have now been uncovered. Even though details are still missing, we understand how SA production is regulated and which molecular machinery is implicated in the control of downstream transcriptional responses. The NPR1 pathway has been described to play the main role in SA transduction. However, the mode of SA perception is unclear. NPR1 protein has been shown to bind SA. Nevertheless, NPR1 action requires upstream regulatory events (such as a change in cell redox status). Besides, a number of SA-induced responses are independent from NPR1. This shows that there is more than one way for plants to perceive SA. Indeed, multiple SA-binding proteins of contrasting structures and functions have now been identified. Yet, all of these proteins can be considered as candidate SA receptors and might have a role in multinodal (decentralized) SA input. This phenomenon is unprecedented for other plant hormones and is a point of discussion of this review.

Salicylic acid 3-hydroxylase regulates Arabidopsis leaf longevity by mediating salicylic acid catabolism.

Project description:The plant hormone salicylic acid (SA) plays critical roles in plant defense, stress responses, and senescence. Although SA biosynthesis is well understood, the pathways by which SA is catabolized remain elusive. Here we report the identification and characterization of an SA 3-hydroxylase (S3H) involved in SA catabolism during leaf senescence. S3H is associated with senescence and is inducible by SA and is thus a key part of a negative feedback regulation system of SA levels during senescence. The enzyme converts SA (with a Km of 58.29 µM) to both 2,3-dihydroxybenzoic acid (2,3-DHBA) and 2,5-DHBA in vitro but only 2,3-DHBA in vivo. The s3h knockout mutants fail to produce 2,3-DHBA sugar conjugates, accumulate very high levels of SA and its sugar conjugates, and exhibit a precocious senescence phenotype. Conversely, the gain-of-function lines contain high levels of 2,3-DHBA sugar conjugates and extremely low levels of SA and its sugar conjugates and display a significantly extended leaf longevity. This research reveals an elegant SA catabolic mechanism by which plants regulate SA levels by converting it to 2,3-DHBA to prevent SA overaccumulation. The research also provides strong molecular genetic evidence for an important role of SA in regulating the onset and rate of leaf senescence.
