SummaryThe aim of this work was to apply the cultured autologous keratinocytes in fibrin glue suspension in treatment of chronic non-healing venous leg ulcers. 32 patients with chronic leg ulcers caused by venous insufficiency were treated. The surface of ulcers covered 14.2 cm2 to 48.6 cm2. The duration of leg ulcer was between 4 to 20 years. The skin specimen 1.0 × 1.0 cm was taken from the buttock of each patient, from which keratinocytes were obtained. Next those cells were cultured. After 7 days the keratinocytes in fibrin glue were applied to the wound bed. After 2 weeks of treatment the ulceration of 13 patients healed completely whereas the ulcer formation of the rest of the patients diminished by 30%. In all patients the process of healing was successfully completed after further 4 weeks. Our method shows that a rapid healing chronic venous leg ulcer can be achieved by keratinocytes in fibrin glue suspension.

Venous leg ulcers are lesions between the ankle joint and the knee caused by chronic venous insufficiency. The Venous Leg Ulcer Self Efficacy Tool (VeLUSET) was developed to measure self-care and self-efficacy in Englishspeaking persons with venous leg ulcers. This study describes the translation and cross-cultural adaptation of the original version of the VeLUSET from English into Swiss French.

Objective: Identification of isolated superficial venous incompetence (SVI) in patients with clinically diagnosed venous leg ulcers using a computerized strain-gauge plethysmograph. Design: Ambulatory leg ulcer patients were assessed as to the clinical diagnosis. Diagnoses other than venous ulceration were excluded. Setting: Department of Dermatology, Sahlgrenska Hospital, Göteborg, Sweden. Patients: One hundred and fourteen patients (133 legs) with venous leg ulcers were investigated. Main outcome measures: All patients were also investigated by measuring systolic ankle and arm pressure measurements. The ankle/arm (AI) was below 0.9 in 22 of the 133 ulcerated legs. Results: Of the 111 ulcerated legs with an AI>0.9, 10% had an isolated SVI. Conclusions: Isolated SVI is an important cause of venous leg ulcer development. Strain-gauge plethysmography is an inexpensive screening method, and is easy to use. Further examination with the more exact, but also more expensive and time-consuming, colour duplex should be performed in selected cases.

ObjectivesTo estimate and examine the direct healthcare costs of treating people with open venous leg ulcers in the UK.DesignCost-of-illness study.SettingA cross-sectional survey of nine National Health Service community locales over 2-week periods in 2015/2016.MethodsWe examined the resource use and prevalence of venous leg ulcer treatment in the community. Examination of variation in these obtained costs was performed by ordinary least squares regression. We used additional resource use information from a randomised control trial and extrapolated costs to the UK for an annual period.ResultsThe average 2-week per person cost of treating patients where a venous leg ulceration was the primary (most severe) wound was estimated at £166.39 (95% CI £157.78 to £175.00) with community staff time making up over half of this amount. Costs were higher where antimicrobial dressings were used and where wound care was delivered in the home. Among those with any recorded venous leg ulcer (primary and non-primary), we derived a point prevalence of 3.2 per 10 000 population and estimated that the annual prevalence could be no greater than 82.4 per 10 000 population. We estimated that the national cost of treating a venous leg ulcer was £102 million with a per person annual cost at £4787.70.ConclusionOur point prevalence figures are in line with the literature. However, our annual prevalence estimations and costs are far lower than those reported in recent literature which suggests that the costs of treating venous leg ulcers are lower than previously thought. Movement towards routinely collected and useable community care activity would help provide a transparent and deeper understanding of the scale and cost of wound care in the UK.

Objectives To evaluate the feasibility of an interventional study involving a seated plantar resistance exercise programme, using a StepIt pedal, aimed at promotion of venous leg ulcer healing. Methods Thirty-two venous leg ulcer patients, recruited from community, GP and hospital settings, were randomised to either a standard care or adjuvant StepIt exercise programme arm for up to 12 weeks. The exercise involved a twice daily routine of 10 times 1 min of exercise, i.e. 2 s push and 2 s lift repetitions (equating to 300 daily ‘steps’). Results Complete healing of the venous leg ulcers was observed in 10 out of 15 (67%; StepIt cohort) and 7 out of 17 (41%; control cohort), respectively (p-value 0.18, Fisher’s exact test). Baseline differences between the two cohorts were longer wound chronicity, less venous leg ulcer-related pain and better venous leg ulcer-related quality of life in the StepIt cohort. One adverse event, involving increased wound exudate and slough production, was observed in a participant using StepIt, and no study withdrawals were recorded in either arm. StepIt users whose wound had completely healed by week 12 were more likely to be compliant with the exercise programme (self-reported) and more positive about the trial experience; however, all would recommend the device to others. Conclusions Seated plantar resistance exercise shows promise and may accelerate venous leg ulcer wound healing. The StepIt pedal is well-received by patients, and its efficacy may depend on the degree of patient compliance with the exercise programme. Further larger scale studies are indicated to allow more concrete inferences to be made on the clinical and potential health economics impact that this device may have.

The aim of this study was to understand which factors influence patients’ adherence to venous leg ulcer treatment recommendations in primary care. We adopted a qualitative study design, conducting phone interviews with 31 people with venous leg ulcers in Melbourne, Australia. We conducted 31 semi-structured phone interviews between October and December 2019 with patients with clinically diagnosed venous leg ulcers. Participants recruited to the Aspirin in Venous Leg Ulcer Randomized Control Trial and Cohort study were invited to participate in a qualitative study, which was nested under this trial. We applied the Theoretical Domains Framework to guide the data analysis. The following factors influenced patients’ adherence to venous leg ulcer treatment: understanding the management plan and rationale behind treatment (Knowledge Domain); compression-related body image issues (Social Influences); understanding consequences of not wearing compression (Beliefs about Consequences); feeling overwhelmed because it’s not getting better (Emotions); hot weather and discomfort when wearing compression (Environmental Context and Resources); cost of compression (Environmental Context and Resources); ability to wear compression (Beliefs about Capabilities); patience and persistence (Behavioral Regulation); and remembering self-care instructions (Memory, Attention and Decision Making). The Theoretical Domains Framework was useful for identifying factors that influence patients’ adherence to treatment recommendations for venous leg ulcers management. These factors may inform development of novel interventions to optimize shared decision making and self-care to improve healing outcomes. The findings from this article will be relevant to clinicians involved in management of patients with venous leg ulcers, as their support is crucial to patients’ treatment adherence. Consultation with patients about VLU treatment adherence is an opportunity for clinical practice to be targeted and collaborative. This process may inform guideline development.

Background: Venous disease is responsible for around 85% of all chronic lower limb ulcers in resource-rich countries. Venous leg ulcer is a chronic condition, and various treatment modalities are available. Various adjunctive wound care therapies and procedures are available that can be utilized as part of a comprehensive approach to healing venous stasis ulcers. Platelet-rich brin (PRF) is one of the newer modalities and it contains broblast growth factor (FGF), VEGF, angiopoietin and platelet-derived GF which enhances the wound healing. We conducted a randomized controlled trial to compare the efcacy of PRF versus saline dressing in chronic venous leg ulcers. Aim: To compare the efcacy of autologous PRF with saline dressing in patients with chronic venous leg ulcer in terms of mean reduction in ulcer area, presence of infection and cosmetic outcome at the end of 4 weeks. Materials and Methods: Thirty patients with chronic venous leg ulcers of >6 months duration having an ulcer area of 1 cm × 1 cm to 5 cm × 5 cm were taken into the study and were randomly divided into two groups. Group 1: Patients received PRF dressing. 10 mL of patient's blood was taken and centrifuged at 3000 rpm for 15 min. A brin clot obtained in the middle of the tube was removed and used for dressing over the wound surface. It was repeated every week for 4 weeks. Group 2: Patients received saline dressings once a week for 4 weeks. The assessment of the ulcer size was done with the help of photographs, and ulcer area was measured. Results: The mean reduction in the area of the ulcer size in PRF group was 81.84%, and the mean reduction in the area of the ulcer size in Saline group was 59.84%. Conclusion: Platelet rich brin matrix is a novel modality and an ideal, safe, affordable therapeutic option for chronic venous leg ulcers.

Objective The aim of the study was to analyze bacterial flora in venous leg ulcers, empiric and targeted antibiotic therapy, and factors influencing healing time. Materials and methods Data from 30 patients with venous leg ulcers were retrospectively analyzed. Collected data included: sociodemographic data, wounds information, number of comorbidities, results of the microbiological examination, and empiric and targeted antibiotic therapy. To compare the empiric and targeted treatment in terms of their compatibility, the group of patients was divided into the four subgroups: NEA (no empiric antibiotics), NA (no antibiotics), ETA+ (compatibility of empiric and targeted antibiotic), ETA− (no compatibility of empiric and targeted antibiotic). Results The average ulcer healing time was 163.4 ± 97.1 (range 51.0 to 426.0) days and increased by 28 days with each additional bacterial strain in the ulcer (p = 0.041). Healing time did not differ between the four groups. Staphylococcus aureus and Pseudomonas aeruginosa were the most frequent bacteria. Amoxicillinium/acidum clavulanicum was the most common empirical antibiotic and amoxicillinium/acidum clavulanicum, and levofloxacinum was the most common targeted antibiotic. Conclusions Venous leg ulcer healing time was prolonged with each subsequent bacterial strain in the ulcer, and it was independent from systemic antibiotic therapy.

BackgroundCompression is an effective and recommended treatment for venous leg ulcers. Although the four-layer bandage (4LB) is regarded as the gold standard compression system, it is recognised that the amount of compression delivered might be compromised by poor application technique. Also the bulky nature of the bandages might reduce ankle or leg mobility and make the wearing of shoes difficult. Two-layer compression hosiery systems are now available for the treatment of venous leg ulcers. Two-layer hosiery (HH) may be advantageous, as it has reduced bulk, which might enhance ankle or leg mobility and patient adherence. Some patients can also remove and reapply two-layer hosiery, which may encourage self-management and could reduce costs. However, little robust evidence exists about the effectiveness of two-layer hosiery for ulcer healing and no previous trials have compared two-layer hosiery delivering ‘high’ compression with the 4LB.ObjectivesPart I To compare the clinical effectiveness and cost-effectiveness of HH and 4LB in terms of time to complete healing of venous leg ulcers.Part II To synthesise the relative effectiveness evidence (for ulcer healing) of high-compression treatments for venous leg ulcers using a mixed-treatment comparison (MTC).Part III To construct a decision-analytic model to assess the cost-effectiveness of high-compression treatments for venous leg ulcers.DesignPart I A multicentred, pragmatic, two-arm, parallel, open randomised controlled trial (RCT) with an economic evaluation.Part II MTC using all relevant RCT data – including Venous leg Ulcer Study IV (VenUS IV).Part III A decision-analytic Markov model.SettingsPart I Community nurse teams or services, general practitioner practices, leg ulcer clinics, tissue viability clinics or services and wound clinics within England and Northern Ireland.ParticipantsPart I Patients aged ≥ 18 years with a venous leg ulcer, who were willing and able to tolerate high compression.InterventionsPart I Participants in the intervention group received HH. The control group received the 4LB, which was applied according to standard practice. Both treatments are designed to deliver 40 mmHg of compression at the ankle.Part II and III All relevant high-compression treatments including HH, the 4LB and the two-layer bandage (2LB).Main outcome measuresPart I The primary outcome measure was time to healing of the reference ulcer (blinded assessment).Part II Time to ulcer healing.Part III Quality-adjusted life-years (QALYs) and costs.ResultsPart I A total of 457 participants were recruited. There was no evidence of a difference in time to healing of the reference ulcer between groups in an adjusted analysis [hazard ratio (HR) 0.99, 95% confidence interval (CI) 0.79 to 1.25;p = 0.96]. Time to ulcer recurrence was significantly shorter in the 4LB group (HR = 0.56, 95% CI 0.33 to 0.94;p = 0.026). In terms of cost-effectiveness, using QALYs as the measure of benefit, HH had a > 95% probability of being the most cost-effective treatment based on the within-trial analysis.Part II The MTC suggests that the 2LB has the highest probability of ulcer healing compared with other high-compression treatments. However, this evidence is categorised as low to very low quality.Part III Results suggested that the 2LB had the highest probability of being the most cost-effective high-compression treatment for venous leg ulcers.ConclusionsTrial data from VenUS IV found no evidence of a difference in venous ulcer healing between HH and the 4LB. HH may reduce ulcer recurrence rates compared with the 4LB and be a cost-effective treatment. When all available high-compression treatments were considered, the 2LB had the highest probability of being clinically effective and cost-effective. However, the underpinning evidence was sparse and more research is needed. Further research should thus focus on establishing, in a high-quality trial, the effectiveness of this compression system in particular.Trial registrationCurrent Controlled Trials ISRCTN49373072.FundingThis project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full inHealth Technology Assessment; Vol. 18, No. 57.
