ABSTRACT

The annual cost to the NHS of managing 3.8 million patients with a wound was estimated in 2020 to be £8.3 billion, of which £5.6 billion was spent on the 30% of wounds that did not heal and £2.7 billion on the 70% of wounds that healed (Guest, 2020). One of the main symptoms associated with chronic 'hard-to-heal' wounds is the production of excess exudate (Atkin et al, 2019). This is due to a prolonged chronic inflammatory response stimulated by a physiological cause. This article describes what exudate is and its importance in the wound healing process, highlighting the consequences of too little or excessive wound exudate associated with any wound. The article goes on to describe a case series observational study involving a range of patients (n=47; 33 male/14 female), aged between 33 and 91 years (mean 67.4 years), with a variety of acute (n=11) and chronic exuding wounds (n=44). In total, 55 wounds of various aetiologies were managed with DryMax Super (a dressing whose design includes superabsorbent polymers) in order to evaluate and report on the absorption and fluid-handling properties of the product.

ABSTRACT

To evaluate the clinical evidence of platelet-rich plasma (PRP) in the treatment of venous ulcers (VUs). Electronic searches were conducted through the Cochrane Library, Web of Science, Embase and PubMed. AMSTAR-2 was used to assess the methodological quality. The quality of evidence was assessed using the GRADE system. According to AMSTAR-2, the methodological quality of the included reviews was generally inadequate owing to the limitations of entries 2, 4 and 7. Due to bias risk and imprecision, the evidence quality of the outcome measures was inadequate. In conclusion, PRP may have a therapeutic effect on VUs. However, this conclusion must be treated with caution due to methodological flaws of the included systematic reviews and meta-analyses.

ABSTRACT

Introduction: Vascular ulcers constitute a serious global public health problem, responsible for causing a significant social and economic impact due to their recurrent, disabling nature and the need for prolonged therapies to cure them. Objective: To evaluate the use and efficacy of the rhEGF in the epithelialization of patients with a diagnosis of CEAP stage 6 venous insufficiency, in the two regimes of the health system in Colombia, the contributive (equivalent to a health system where citizens with payment capacity contribute a percentage of their salary) and the subsidized (equivalent to a health system where the state covers the vulnerable population and low socioeconomic level) versus the other treatments used. Methodology: Observational, descriptive, retrospective, multicenter study, in which 105 medical records with 139 ulcers were reviewed, in 2 centers, one belonging to the subsidized system and the other to the contributive system in Colombia. Results: The association with the epithelialization variable of the different treatment groups for ulcers according to the application of the mixed effect model test, for both regimes was for the Biologicals (EC 34.401/p = 0.000), Bioactive Agents (Hydrogels) (EC 24.735/p = 0.005) groups; for the rest of the treatment groups, the results were neither associated nor statistically significant. Conclusion: Intra- and perilesional therapy with rhEGF expands the therapeutic spectrum in patients with venous ulcers, regardless of the type of health system in which it will be applied, shortening the healing time and reaching a possible therapeutic goal, which according to this study there is an association with epithelialization regardless of the regime applied.

ABSTRACT

Venous stasis ulcers are nonhealing lesions due to venous hypertension secondary to valvular dysfunction or deep venous outflow obstruction. We describe a case of a 71-year-old male with a history of polycythemia vera, secondary myelofibrosis, and massive splenomegaly up to 38 cm who presented with chronic, perimalleolar venous stasis ulcers and pain on the left lower extremity. CT showed significant compression of the left common iliac vein due to mass effect from the spleen. He was managed medically while being evaluated for partial splenic artery embolization but expired due to other chronic conditions before any intervention could be performed. Partial splenic artery embolization may be considered as a treatment option for patients with symptomatic iliac vein compression due to massive splenomegaly secondary to myelofibrosis, as long as extramedullary hematopoiesis is not compromised.

ABSTRACT

Chronic wounds pose a significant threat to human health, particularly for the elderly, and require extensive healthcare resources globally. Autophagy, a key molecular player in wound healing, not only offers a defense against infections but also contributes to the deposition of the extracellular matrix during the proliferative phase. Additionally, it promotes the proliferation and differentiation of endothelial cells, fibroblasts, and keratinocytes. We have recently shown that applying magnetized saline water topically can trigger autophagy in intact skin. In this case series, we document the successful management of five non-infected, difficult-to-heal wounds in elderly patients using a topical autophagy-stimulating gel containing 95% magnetized saline water. The treated wounds included pressure ulcers, venous ulcers, and trauma-related injuries that had shown minimal or no improvement with standard wound therapies over a prolonged period. Application of the autophagy-stimulating gel promoted wound healing, as indicated by reduced fibrous and necrotic tissue, granulation tissue formation, re-epithelialization, and partial or complete wound closure. These preliminary case studies suggest that a topical gel containing magnetized saline water, which promotes autophagy, may aid healing of chronic wounds in elderly patients. Further investigation is warranted to explore the potential of this novel approach, as it may offer a valuable addition to the existing arsenal of wound care treatments for the aging population, particularly in addressing difficult-to-heal wounds.

ABSTRACT

This study aimed to assess the efficacy of human amniotic membranes (HAM) in treating venous and diabetic ulcers, which often pose challenges in healing. A systematic review and meta-analysis were conducted, evaluating 10 relevant studies involving 633 participants. Findings revealed that HAM treatment significantly accelerated ulcer closure, demonstrating over 90% complete healing compared to standard care. Despite moderate heterogeneity among studies, the results strongly suggested the effectiveness and safety of HAM therapy for venous and diabetic leg ulcers. Further research with larger study cohorts is recommended to bolster the existing evidence supporting HAM in managing these challenging wounds.

ABSTRACT

Background and Objectives: The clinical relevance of "corona phlebectatica" and the management of risk factors for recurrence of venous ulcers in patients with chronic venous disease may be variable based on vascular specialists in different geographical areas of Italy. The aim of the present survey is to evaluate the management of patients with chronic venous disease by vascular specialists in different areas of the national territory. In particular, this involves ascertaining the clinical/prognostic relevance attributed to the presence of the "corona phlebectatica" as well as to the management of risk factors related to recurrence of venous ulcers. Materials and Methods: The web-based survey aimed at vascular medicine specialists with particular interest in venous disease. A questionnaire was developed, based on 12 questions, in relation to clinical assessment, risk factor management, and therapy in patients with chronic venous disease. Results: Almost all of the specialists involved actively participated in the survey, declaring that they personally manage chronic venous disease overall. There was a strong agreement in the prognostic consideration attributed to the presence of "corona phlebectatica" and to the management of risk factors for venous ulcer recurrence, regardless of the different geographical areas of interest. Conclusions: Accordingly with the results of this self-assessment survey, the skills and experience of the specialists involved appear to be of a good standard, both in the clinical evaluation and in the management of the progression of chronic venous disease. However, the need to reach more cultural insights into the correlations between chronic venous disease and risk factors correlated with disease progression emerges. Moreover, there was the need for a greater and tighter overall clinical control of a patient with chronic venous disease, also in relation to the presence of comorbidities.

ABSTRACT

This study aimed to investigate the causal relationship between inflammatory cytokines and the risk of varicose veins. The data were sourced from genome-wide association studies (GWAS) of European individuals. Multiple Mendelian randomization (MR) methods were used to evaluate the association between inflammatory cytokines and varicose veins. The study found significant associations between elevated levels of certain inflammatory biomarkers (e.g., CASP-8, Vascular endothelial growth factor A levels (VEGF_A)) and an increased risk of varicose veins, while others (e.g., 4EBP1, MMP-10) showed a protective effect. The MR-Egger Intercept and heterogeneity tests indicated no significant pleiotropy or heterogeneity. This comprehensive MR analysis identifies several cytokines as potential contributors to the pathogenesis of varicose veins, offering insights into novel therapeutic targets. Our findings underscore the importance of inflammation in varicose veins and suggest that targeting specific cytokines could be a promising strategy for the treatment and prevention of varicose veins.

ABSTRACT

INTRODUCTION: Chronic non-healing leg ulcers are skin defects below the knee that resist healing for more than six weeks. They cause physical, emotional, and economic burdens to patients and society. OBJECTIVES: To introduce an innovative medical strategy that targets the chronic inflammation component in non-healing ulcers (NHUs) with rheumatic features and to evaluate its potential effectiveness in achieving complete healing. METHODS: We employed an empirical medical therapy regimen, which combined medications like deflazacort, colchicine, dapsone, hydroxychloroquine, and azathioprine. We retrospectively selected 25 patients with chronic pedal ulcers who underwent our therapy. RESULTS: The mean duration of ulcers was 7.84 years, and the time to heal was 5.97 months. Among 25 patients, 19 had atypical ulcers, four had venous ulcers, and two had diabetic neuropathy ulcers. Four patients with venous ulcers additionally underwent endovenous laser ablation. CONCLUSION: Our medical strategy showed promising results in healing chronic NHUs with rheumatic features without significant steroid-induced adverse effects.

ABSTRACT

Chronic wounds are a common and costly health issue affecting millions of individuals in the United States, particularly those with underlying conditions such as diabetes, venous insufficiency, and peripheral artery disease. When standard treatments fail, advanced wound care therapies, such as skin substitutes, are often applied. However, the clinical effectiveness, indications, and comparative benefits of these therapies have not been well established. In this study, we report on the usage of both acellular and cellular, single and bilayer, natural and synthetic, dermal, and epidermal skin substitutes in a VA hospital system. We performed a retrospective chart review to understand the ordering and usage patterns of advanced wound therapies for patients with chronic wounds at the VA Northern California Health Care System. We examined types of products being recommended, categories of users recommending the products, indications for orders, and rate of repeated orders. Neuropathic, venous, or pressure ulcers were the main indications for using advanced wound matrices. Only 15.6% of patients for whom the matrices were ordered had supporting laboratory tests. Exactly 34.3% of the ordered matrices were not applied. And the use of wound matrices resulted in increased costs per patient visit of $1018-$3450. Our study sheds light on the usage patterns of these therapies in a VA healthcare facility and highlights the need for more robust evidence-based studies to determine the true benefits, efficacy, and cost-effectiveness of these innovative treatment options.

ABSTRACT

Venous insufficiency is a common medical condition that affects many individuals, especially those with advanced age. Chronic venous insufficiency can lead to secondary cutaneous changes that most commonly present as stasis dermatitis but can progress to more serious venous ulcers. Although venous ulcers are the most common cause of lower extremity ulcers, the differential diagnosis of leg ulcers is broad. This article will discuss clinical clues to help guide patient workup and will review basic clinical evaluation and management of common leg ulcers.

ABSTRACT

The present study showed a significant association between varicose veins and the development of osteoporosis, especially women and patients older than 50 years. Physicians should be alerted to this issue and consider screening for osteoporosis in patients with varicose veins. PURPOSE: Osteoporosis might be associated with many skin diseases. However, only a paucity of data addressing the association between varicose veins and subsequent osteoporosis development. The study was aimed to evaluate whether there is an increased risk of osteoporosis among patients with varicose veins. METHODS: This multi-institution database study was based on Chang Gung Research Database from January 1, 2003, to December 31, 2015. Patients aged 20 years and older with varicose veins were enrolled. Participants in the control group were selected by matching in a 4:1 ratio by sex, age, index date, and comorbidities. The hazard ratios associated with osteoporosis were estimated using Cox regression analysis with competitive risk model. Incidence rate of osteoporosis was assessed in individuals with and without varicose veins. RESULTS: A total of 11,959 patients with varicose veins and 47,633 matched controls were enrolled in the study. The varicose veins group had higher incidence rates than the control group for osteoporosis (46.40 vs 31.92 per 10,000 person-years; adjusted HR 1.481 [95%CI, 1.314-1.669; P < 0.001]). Compared with matched controls, varicose veins patients with or without venous ulcers had 1.711- and 1.443-times increased risk of developing osteoporosis, respectively. Subgroup analysis showed varicose veins were associated with osteoporosis in women and patients older than 50 years. CONCLUSION: The present study demonstrated individuals with varicose veins had an increased risk of osteoporosis. Physicians should be alerted to this issue and consider screening for osteoporosis in patients with varicose veins, especially among women and patients older than 50 years.

ABSTRACT

Bacterial proliferation plays a well-known role in delayed tissue healing. To date, the presence of microorganisms on the wound bed can be detected by skin swabs or skin biopsies. A novel noninvasive fluorescence imaging device has recently allowed real-time detection of bacteria in different types of wounds through endogenous autofluorescence. The fluorescence signals detected by the device provide health workers with a visual indication of the presence, load, and distribution of bacteria. The aim of our study was to evaluate the level of bacterial colonization in perilesional skin of patients affected by venous leg ulcers treated with 2 different types of bandages: short stretch bandage and zinc oxide bandage. We conducted a monocentric prospective study, enrolling 30 patients with venous leg ulcers, divided into 2 groups: group A was treated with short stretch bandage and group B with zinc oxide bandage. A complete patient's assessment was performed once a week for 3 weeks. Levels of potentially harmful bacteria in perilesional skin were detected using a fluorescent device by 2 experienced operators on the frames taken at individual injuries, while pain was evaluated with the Numerical Rating Scale. After 3 weeks, we observed a reduction in the bacterial colonization levels of the perilesional skin by 68.67% for group A and 85.54% for group B. All the patients had a statistically significant reduction in bacterial load (P < .001), and a statistically significant difference was identified between the 2 groups (P = .043). No statistically significant differences were found between the 2 groups in terms of pain relief (P = .114). Our study demonstrated that the application of zinc oxide bandage provides a higher reduction in bacterial load perilesional skin. On the other hand, we found no difference between the 2 bandages in terms of pain symptom reduction.

ABSTRACT

Healing of skin wounds of the lower extremities can be complicated by concomitant vascular disease. Dysfunction of the arterial, venous, and/or lymphatic systems can compromise the healing of skin ulcers of the legs, creating a burden for patients from painful, draining wounds and placing patients at risk for infection, amputation, and even death. Insights into vascular pathophysiology and an understanding of the processes of wound healing permit an evidence-based approach to patients with vascular leg ulcers. Clinical trials have demonstrated opportunities to improve the care of patients with vascular leg ulcers, thereby reducing morbidity and mortality and easing patients' burdens.

ABSTRACT

The case study described in this article shows the use of different approaches and techniques that need to be utilised when treating patients presenting with a combination of venous and lymphatic disease (lymphovenous) in order to improve complex wound outcomes. The author highlights how lymphoedema can affect the wound healing process by increasing the risk of recurrent infection and a hardening of the tissues (fibrosis), reducing oxygenation and lymphatic flow to the wound, leading to chronic complex wounds.

ABSTRACT

The underpinning of Chronic Venous Insufficiency (CVI) is valvular dysfunction, which manifests on a spectrum depending on the severity of insufficiency and duration of the disease. The mainstay of treatment relies on compression therapy of a proper type and intensity. In older adults, special consideration must be taken during the patient encounter to account for age-related factors. This review discusses the clinical presentation, diagnosis, and mimicking of CVI, focusing mainly on older adults. The epidemiology, risk factors, disease burden, and grave complications -- such as thrombosis and ulceration, are reviewed. The physiological impacts of CVI are described, providing the background for treatment strategies, including non-invasive, medical, and surgical therapies. The findings show advanced age to be an important risk factor contributing to CVI and that other age-related factors add to the risk of severe complications. Clinical assessments combined with objective measurements that assess localized skin water using tissue dielectric constant values or whole limb assessments may aid in the differential diagnosis. Furthermore, understanding the mechanism of action of compression therapy, the mainstay of CVI treatment, and its physiological impacts, allows for its informed use in geriatric patients with increased risks of potential compression-related side effects.

ABSTRACT

OBJECTIVE: The aim of this study was to establish the efficacy of three different strengths of compression systems in the prevention of venous leg ulcer (VLU) recurrences during a 10-year follow up period. METHODS: An open, prospective, randomized, single-center study included 477 patients (240 men, 237 women; mean age 59 years). Patients were randomized into three groups: Group A) 149 patients (allocated to wear elastic stocking 18-25 mmHg). Group B) 167 patients (wearing compression device exerting 25-35 mmHg), and Group C) 161 patients (treated with multilayer compression system exerting 35-50 mmHg). RESULTS: Overall, 65% (234/360) of patients had recurrent VLU within 10 years. Recurrence occurred in 120 (96%) of 125 in group A, in 89 (66.9%) of 133 patients in group B and in 25 (24.5%) of 102 patients in group C (p < 0.05). CONCLUSION: Compression systems with the higher compression class provide lower recurrence rate.

ABSTRACT

Leg ulcers are a common and often serious problem in older adults. Underlying conditions that increase risk include age-related increases in chronic venous insufficiency, peripheral artery disease, connective tissue and autoimmune conditions, reduced mobility, and diabetes mellitus (DM). Geriatric patients have a higher risk of multiple wound-related complications including infection, cellulitis, ischemia, and gangrene, any of which may lead to further complications including amputation. The very presence of these lower extremity ulcers in the elderly negatively impacts their quality of life and ability to function. Understanding and early identification of the underlying conditions and wound features are important for effective ulcer healing and complication mitigation. This targeted review focuses on the three most common types of lower extremity ulcers: venous, arterial, and neuropathic. The goal of this paper is to characterize and discuss the general and specific aspects of these lower extremity ulcers and their relevancy and impact on the geriatric population. The top five main results of this study can be summarized as follows. (1) Venous ulcers, caused by inflammatory processes secondary to venous reflux and hypertension, are the most common chronic leg ulcer in the geriatric population. (2) Arterial-ischemic ulcers are mainly due to lower extremity vascular disease, which itself tends to increase with increasing age setting the stage for an age-related increase in leg ulcers. (3) Persons with DM are at increased risk of developing foot ulcers mainly due to neuropathy and localized ischemia, both of which tend to increase with advancing age. (4) In geriatric patients with leg ulcers, it is important to rule out vasculitis or malignancy as causes. (5) Treatment is best made on a case-by-case basis, considering the patient's underlying condition, comorbidities, overall health status, and life expectancy.

ABSTRACT

Current therapeutic approaches for chronic venous ulcers (CVUs) still require evidence of effectiveness. Diverse sources of extracellular vesicles (EVs) have been proposed for tissue regeneration, however the lack of potency tests, to predict in-vivo effectiveness, and a reliable scalability have delayed their clinical application. This study aimed to investigate whether autologous serum-derived EVs (s-EVs), recovered from patients with CVUs, may be a proper therapeutic approach to improve the healing process. A pilot case-control interventional study (CS2/1095/0090491) has been designed and s-EVs recovered from patients. Patient eligibility included two or more distinct chronic lesions in the same limb with 11 months as median persistence of active ulcer before enrollment. Patients were treated three times a week, for 2 weeks. Qualitative CVU analysis demonstrated that s-EVs-treated lesions displayed a higher percentage of granulation tissue compared to the control group (Sham) (s-EVs 3 out of 5: 75-100 % vs Sham: none), further confirmed at day 30. s-EVs-treated lesions also displayed higher sloughy tissue reduction at the end of treatment even increased at day 30. Additionally, s-EV treatment led to a median surface reduction of 151 mm2 compared to 84 mm2 in the Sham group, difference even more evident at day 30 (s-EVs 385 mm2vs Sham 106 mm2p = 0.004). Consistent with the enrichment of transforming growth factor-ß1 in s-EVs, histological analyses showed a regenerative tissue with an increase in microvascular proliferation areas. This study first demonstrates the clinical effectiveness of autologous s-EVs in promoting the healing process of CVUs unresponsive to conventional treatments.

ABSTRACT

Chronic wounds are associated with significant clinical, economic and quality-of-life burden. Despite the variety of wound imaging systems available in the market for wound assessment and surveillance, few are clinically validated among patients of Asian ethnicity. We aimed to clinically validate the accuracy of a smartphone wound application (Tissue Analytics [TA], Net Health Systems Inc, Florida, USA), versus conventional wound measurements (visual approximation and paper rulers), in patients of Asian ethnicity with venous leg ulcers (VLU). A prospective cohort study of patients presenting with VLU to a specialist wound nurse clinic over a 5-week duration was conducted. Each patient received seven wound measurements: one by a trained wound nurse clinician, and three separate wound measurements using TA on each of the iOS and Android operating systems. Inter-rater and intra-rater reliability between clinical and TA-based measurements were analysed using intra-class correlation statistics, with values of <0.5, 0.5 to 0.75, 0.75 to 0.9, and >0.9 indicating poor, moderate, good and excellent reliability, respectively. 82 patients (51% males), with a mean age at 65.8 years, completed the 5-week study duration. 25 (30%) had underlying diabetes mellitus. Chinese, Malay and Indian ethnicity comprised 68%, 12% and 11%, respectively. The VLU healed in 26 (32%) of patients within the study period. In total, 358 wound episodes with 2334 wound images were analysed. Inter-rater reliability for length, width and area between wound nurse measurements and TA application measurements was good (range 0.799-0.919, P < 0.001). Separate measurements of intra-rater reliability for length, width and area within the iOS or Android systems were excellent (range 0.967-0.985 and range 0.977-0.984 respectively, P < 0.001). Inter-rater reliability between TA used on the iOS and Android systems was also excellent (0.987-0.989, P < 0.001). Tissue Analytics, a smartphone wound application, is a useful adjunct for wound assessment and surveillance in VLU patients of Asian ethnicity.
