RESUMEN

For assessing health-related quality of life in patients with chronic wounds, the Wound-QoL questionnaire has been developed. Two different versions exist: the Wound-QoL-17 and the Wound-QoL-14. For international and cross-cultural comparisons, it is necessary to demonstrate psychometric properties in an international study. Therefore, the aim of this study was to test both questionnaires in a European sample, using item response theory (IRT). Participants were recruited in eight European countries. Item characteristic curves (ICC), item information curves (IIC) and differential item functioning (DIF) were calculated. In both questionnaires, ICCs for most items were well-ordered and sufficiently distinct. For items, in which adjacent response categories were not sufficiently distinct, response options were merged. IICs showed that items on sleep and on pain, on worries as well as on day-to-day and leisure activities had considerably high informational value. In the Wound-QoL-14, the item on social activities showed DIFs regarding the country and age. The same applied for the Wound-QoL-17, in which also the item on stairs showed DIFs regarding age. Our study showed comparable results across both versions of the Wound-QoL. We established a new scoring method, which could be applied in international research projects. For clinical practice, the original scoring can be maintained.

RESUMEN

Objective: To evaluate patient reported outcome measures after early clot removal for acute deep vein thrombosis (DVT), using the Chronic Venous Disease Quality of Life Questionnaire (CIVIQ-20) and the Short Form Health Survey (SF-36). Methods: Cross sectional design. Patients who underwent early clot removal between June 2012 and November 2021 were asked to complete the two questionnaires once. Lower CIVIQ-20 and higher SF-36 scores indicate better quality of life (QoL). Primary endpoints were the median scores. The one sample Wilcoxon signed rank test was used to compare SF-36 physical and mental component summary (PCS and MCS) to the normative and CIVIQ-20 to the minimum. Secondary, non-parametric independent t test or Fisher's exact test examined how age, sex, body mass index, stent placement, re-intervention, and time of questionnaire completion related to QoL. Multivariable linear regression tested whether various variables were associated with QoL. Results: The response rate was 73.5% (n = 39). Median time of questionnaire completion was 1.8 years (interquartile range [IQR] 3.1) after clot removal. The median CIVIQ-20 of 29.0 (IQR 28.0) was slightly higher than the minimum value 20.0 (p < .001). The median PCS (50.5, IQR 16.6) and median MCS (50.2, IQR 14.2) did not differ from the normative of 50.0. However, wide IQRs indicated impairments for a subgroup of patients. None of the tested variables affected QoL except for the finding that re-interventions had a significantly negative impact on the SF-36 MCS (standardised ß coefficient of -0.4, p = .030). Conclusion: Overall patient reported outcome measures were satisfactory after early clot removal, but impaired physical and mental functioning levels were present in a subgroup of patients. Re-interventions were found to have a negative impact on mental QoL. This finding was independent of time that had passed between the procedure and questionnaire completion. This study emphasises that mental functioning deserves attention, besides the widely recognised physical consequences after invasive acute iliofemoral DVT treatment.

RESUMEN

OBJECTIVE: Patients with PTS experience an impaired quality of life (QoL). We aimed to study QoL in patients stented for post thrombotic syndrome (PTS) and analyze the influence of different parameters. METHODS: Patients stented for PTS after iliofemoral deep vein thrombosis were asked to complete the Chronic Venous Disease Quality of Life Questionnaire (CIVIQ-20) and the Short Form Health Survey (SF-36) in this cross-sectional study. All other data were collected retrospectively. Primary endpoints were median CIVIQ-20 and physical (PCS) and mental (MCS) component summary SF-36 scores. The influence of age, sex, and years between the procedure and completion of questionnaire were investigated using a multivariate linear regression model. Wilcoxon signed rank test compared the PCS and MCS with the normative. Effects of inflow from the deep femoral vein (DFV) and/or the femoral vein (FV) on QoL was analyzed in patients with patent stents. RESULTS: The response rate was 70.3% (n = 45/64). Time period (median) from stenting to questionnaire completion was 6.6 years (IQR: 8.0). Most stents were placed unilateral left-sided (73.3%). For patients with patent stents (n = 42) median CIVIQ-20 was 35.5 (IQR: 17.3), higher than the minimum of 20.0 (P < .001). Median PCS of 44.7 (IQR: 14.2) was lower (P < .001), and MCS of 55.9 (IQR: 7.1) higher (P = .001) than the normative (50.0). Time since stenting and sex were not associated with QoL. Age was a significant predictor [standardized coefficient ß = .36, P = .04] for QoL using the CIVIQ-20, but not for the SF-36. Inflow disease did not impact QoL, but patients with occluded stents (n = 3) had poor functioning levels. CONCLUSION: Quality of life is impaired after venous stenting for PTS, particularly physical functioning, among patients with an open stent, but was similar between patients with good and impaired inflow. Patients with a permanent stent occlusion had the lowest QoL.

RESUMEN

The Wound-QoL assesses the impact of chronic wounds on patients' health-related quality of life (HRQoL). A 17-item and a shortened 14-item version are available. The Wound-QoL-17 has been validated for multiple languages. For the Wound-QoL-14, psychometric properties beyond internal consistency were lacking. We aimed to validate both Wound-QoL versions for international samples representing a broad range of European countries, including countries for which validation data had yet been pending. Patients with chronic wounds of any aetiology or location were recruited in Austria, Lithuania, the Netherlands, Poland, Slovakia, Spain, Switzerland and Ukraine. Psychometric properties were determined for both Wound-QoL versions for the overall sample and, if feasible, country-wise. We included 305 patients (age 68.5 years; 52.8% males). Internal consistency was high in both Wound-QoL-17 (Cronbach's α: 0.820-0.933) and Wound-QoL-14 (0.779-0.925). Test-retest reliability was moderate to good (intraclass correlation coefficient: 0.618-0.808). For Wound-QoL-17 and Wound-QoL-14, convergent validity analyses showed highest correlations with global HRQoL rating (r = 0.765; r = 0.751) and DLQI total score (r = 0.684; r = 0.681). Regarding clinical data, correlations were largest with odour (r = -0.371; r = -0.388) and wound size (r = 0.381; r = 0.383). Country-wise results were similar. Both Wound-QoL versions are valid to assess HRQoL of patients with chronic wounds. Due to its psychometric properties and brevity, the Wound-QoL-14 might be preferrable in clinical practice where time is rare. The availability of various language versions allows for the use of this questionnaire in international studies and in clinical practice when foreign language patients are being treated.

RESUMEN

Chronic wounds can severely limit patient's social life. This cross-sectional study investigated quantitatively social support of patients with chronic wounds, its association with health-related quality of life as well as qualitatively changes in social participation of these patients. Overall, 263 patients from seven countries participated. The most frequent wound class was leg ulcer (49.2%). Results revealed generally high levels of social support (mean global score: 5.5) as measured with the Multidimensional Scale of Perceived Social Support. However, individuals differed considerably (range 1.0-7.0). All dimensions of social support differed by patients' family and living situations (p < 0.001 to p = 0.040) and were positively correlated with generic health-related quality of life (r = 0.136-0.172). Having children, living with others and being in a relationship were significant predictors of having higher global social support. Patients reported great support from family members. Many participants reported no changes in relationships with friends. Wound care managers took an important role and provided additional emotional support. Patients reported a range of discontinued activities. Despite the high overall level of social support, inter-individual differences should be acknowledged. The importance of family carers should be acknowledged to be able to reduce caregiver burden and to ensure high-qualitative wound care.

RESUMEN

OBJECTIVE: Venous stenting is performed increasingly for acute deep vein thrombosis (DVT) and post-thrombotic syndrome (PTS) with good short term patency results, but long term data are scarce. The purpose of this study was to evaluate long term outcome of stenting for acute DVT and PTS and to study causes of re-intervention. METHODS: All patients stented for acute DVT and PTS between May 2006 and November 2021 were included retrospectively in this single centre cohort study. Patency was studied by duplex ultrasound (DUS) or computed tomography. The primary endpoint was stent patency. Re-intervention free survival was calculated using Kaplan-Meier methods. Secondary endpoints were causes of re-intervention, using the Pouncey classification system (2022). Binary logistic regression was used to calculate odds ratios for predictors of re-intervention. RESULTS: A total of 114 patients were included, with 129 limbs involved (acute DVT n = 53; 41%), PTS n = 76; 59%). Median follow up was 2.3 years (interquartile range [IQR] 2.3) for acute DVT and 5.2 years (IQR 7.1) for PTS. Primary patency, secondary patency, and permanent occlusion were 73.5%, 98.1%, and 1.9% for acute DVT, and 63.2%, 92.1%, and 7.9% for PTS limbs. Overall, 41 limbs underwent at least one re-intervention: 14 in the acute DVT group and 27 for PTS. Most re-interventions (82.9%) were performed within the first year after stenting. Missed inflow, insufficient flow, and thrombosis despite anticoagulation were the most common causes of re-intervention. The strongest predictor for re-intervention for PTS was inflow disease (odds ratio 3.57, 95% confidence interval 1.26 - 10.13, p= .017). CONCLUSION: Long term patency of deep venous stenting is good. Re-interventions are typically performed in the first year and are potentially preventable by improving the procedure and patient selection. Since secondary patency rates are excellent, selected patients may be considered for discharge from long term surveillance.

RESUMEN

BACKGROUND: After excision surgery in patients with hidradenitis suppurativa (HS), wounds are usually left open for secondary intention healing. To evaluate wound healing, reliable wound measurement is important. However, digital wound measurement tools for measuring the surface area are validated for small wounds located on flat or mildly convex body surfaces in studies, often powered inadequately. Up until now, a validated digital measurement tool to accurately measure wounds on all body surfaces, including the intertriginous areas, was not available. OBJECTIVES: The aim of this study was to validate two digital wound measurement tools for the measurement of the surface area of larger and concave wounds, using surgical wounds in patients with HS. METHODS: This prospective observational validation study included consecutive patients with HS undergoing excision surgery in the Department of Dermatology of the Erasmus University Medical Center, Rotterdam. Wound measurements using a ruler, the tracing method, the inSight® 3-dimensional (3D) device, and the ImitoWound app were performed by three investigators. The intraclass correlation coefficients (ICCs) for concurrent validity and the intra- and inter-rater reliability were analyzed. The standard error of measurement (SEm) and minimal detectable change were calculated, and Bland-Altman plots were constructed to determine the limits of agreement. RESULTS: Twenty patients with a total of 52 wounds were included. The wounds had a mean surface of 18.7 cm2. The inSight® 3D device showed an ICC of 0.987 for concurrent validity, 0.998 for intra-rater reliability, and 0.997 for inter-rater reliability. The ICCs from the ImitoWound application were 0.974, 0.978, and 0.964 for concurrent validity, intra-rater reliability, and inter-rater reliability, respectively. The SEms for intra- and inter-rater reliability were 0.95 cm2 and 1.11 cm2 for the inSight® 3D device and 3.33 cm2 and 3.51 cm2 for the ImitoWound app, respectively. CONCLUSION: Both the inSight® 3D device and the ImitoWound app demonstrated excellent concurrent validity and reliability for the surface measurements of concave wound, enabling these tools to be used reliably in clinical research and daily practice. Furthermore, it paves the way for broader application, such as telemonitoring of wound care at home.

RESUMEN

BACKGROUND: Although leg ulcers are a burdensome disease most common in those aged 65 years and older, frailty in this population has not yet been well established. OBJECTIVES: The aim of this study was to prospectively explore and compare the presence of frailty in elderly patients with chronic leg or foot ulcers by applying different validated frailty screening methods in three healthcare settings and to assess the feasibility of frailty screening. METHODS: We compared frailty of leg ulcer patients referred to an academic hospital with a non-academic hospital, leg ulcer patients receiving (primary) homecare, and a dermato-oncology patient population (control group). Frailty and quality of life were assessed using four validated questionnaires: the Groninger Frailty Indicator, Geriatric-8, Mini-Cog and Wound Quality of Life. To analyse data multiple (non)-parametric tests were performed. RESULTS: Fifty of 60 included leg ulcer patients (83%) scored "frail" on at least one frailty questionnaire (GFI, G8 or Mini-Cog). The number of patients scoring "frail" on two or three out of three applied frailty questionnaires were significantly higher in the academic and homecare ulcer population compared with the non-academic ulcer population and control group (p = 0.002). In the academic ulcer population mean Wound Quality of Life scores were 30.2 (SD 17.6), compared with 17.7 (SD 13.1) in the non-academic and 15.0 (SD 10.4) in the homecare ulcer population (p = 0.002). CONCLUSION: The majority of patients suffering from leg ulcers in this study was frail. The highest frailty prevalence was observed in the academic and homecare ulcer populations. The largest impaired quality of life was reported in the academic ulcer population. In dermatology practice, implementing frailty screening and initiating appropriate (paramedical) supportive care should be considered to improve patient outcomes.

RESUMEN

The Wound-QoL is an often used reliable and valid measure, originally developed in Germany. It has been sequentially translated and validated for other languages/countries, for the measurement of health-related quality of life (HRQoL) in patients with chronic wounds. However, a study from the United States postulated its benefits from further adaptations. Furthermore, some patients struggled to provide an answer for some of the items. We aimed to test the cross-cultural structure and psychometric performance of the questionnaire to suggest necessary revisions. This cross-sectional analysis of existing data sets included 1185 patients from Germany, the US, the Netherlands, Spain, Sweden, and Israel. Patients in the U.S. Wound Registry completed the Wound-QoL during routine care. Different studies comprised the data collection in the other countries. Almost half of the patients were women (48.4%). Furthermore, 42.6% were diagnosed with leg ulcers. Their average age was 66 years. We used a confirmatory factor analysis and an unconstrained graded response model. We revised and shortened the Wound-QoL from 17 to 14 items. In addition, we supported the cross-cultural metric invariance of the revised Wound-QoL questionnaire. The new version with 14 items and three dimensions revealed good psychometric properties with Cronbach's alpha (α) of 0.913 for the total score, and 0.709-0.907 for different dimensions. Furthermore, we provided strict invariance for different clinical variables. In conclusion, the revised Wound-QoL is a reliable and cross-cultural instrument to measure the HRQoL on patients with chronic wounds. Future studies should analyse the revised Wound-QoL for convergent validity with generic HRQoL questionnaires as well as for determining its sensitivity to clinical change.

RESUMEN

The incidence of non-healing wounds is increasing. Identification of the underlying cause of a wound is of essential importance for adequate treatment. In this article, we present three female patients aged 50, 65 and 85 years with respectively pyoderma gangraenosum, livedoid vasculopathy and Martorell hypertensive ischaemic leg ulcer. All patients were treated with local wound care for weeks without a valid diagnosis. In retrospect it can be concluded that several warning signals had not been recognised. Severe pain, atypical location or appearance, insufficient healing and progression of the wound despite adequate wound care should all be considered red flags. Patients with non-healing wounds require prompt referral and more extensive diagnostic investigation. Our cases also show that a multidisciplinary wound care team ensures and accelerates consensus on diagnosis and treatment plan. Such a team can ensure and coordinate follow-up in the home environment.

RESUMEN

BACKGROUND: Chronic wounds have a major impact on patients' health-related quality of life (HRQoL). Therefore, measuring HRQoL is an indispensable part of the treatment of patients with chronic wounds. The aim of this study was to translate and validate the Wound-QoL, a wound-specific HRQoL questionnaire, in a Dutch population. METHODS: The Wound-QoL was translated into Dutch according to the international standards. Patients with chronic wounds were asked to complete questionnaires at baseline (T0) and after six weeks (T1), including Wound-QoL, EQ-5D-3L (a generic questionnaire to measure HRQoL) and a visual analogue scale (VAS) measuring wound pain. If patients were not able to complete the questionnaire by themselves, it was read out to them by a nurse. Further data were obtained from medical records. RESULTS: Of the 120 patients included, 64 (53.3%) completed the questionnaire by themselves. To 55 patients (45.8%), the questionnaire was read out. The internal consistency of the Wound-QoL global score was high at both time points (T0: Cronbach's α = 0.89, T1: Cronbach's α = 0.92). The item selectivity for global score ranged from r = 0.25 to r = 0.77 at T0 and from r = 0.40 to r = 0.79 at T1. Overall, the self-completion and read-out subgroups showed similar internal consistency and item selectivity scores. With regard to convergent validity, significant correlations were found between Wound-QoL and EQ-5D-3L (T0: r = - 0.45, p < 0.001, T1: r = - 0.50, p < 0.001) as well as between Wound-QoL and pain VAS (T0: r = 0.23, p = 0.012, T1: r = 0.37, p = 0.001) at both time points. Responsiveness analyses showed significant correlations between changes in Wound-QoL and changes in EQ-5D-3L (r = - 0.37, p < 0.001), pain VAS (r = 0.24, p = 0.044) and wound size (r = 0.24, p = 0.013). The self-completion and read-out subgroups showed differences in convergent validity and responsiveness. CONCLUSIONS: The results indicate that the Dutch version of the Wound-QoL has positive psychometric properties. However, more research is needed to further explore the differences between self-completed and read-out questionnaires.

RESUMEN

Lentigo maligna (LM) is treated to prevent progression to lentigo maligna melanoma (LMM). Surgery is the gold standard but an alternative treatment is off-label topical imiquimod. The aim of this study was to evaluate the effectiveness of 5% topical imiquimod treatment for lentigo maligna. In the period 2007-2017 57 patients with lentigo maligna were treated with off-label topical imiquimod once daily for 12 weeks. Complete clinical clearance was observed in 48 patients (84.2%) and partial clearance in 3 patients (5.3%). Three patients (5.3%) showed no response and another 3 patients (5.3%) stopped treatment due to side-effects. After 4.5 years during follow-up one patient developed a lentigo maligna melanoma which was subsequently excised. Treatment with topical imiquimod resulted in complete clearance of lentigo maligna in 48 out of 57 patients (84.2%). Topical imiquimod is an acceptable treatment option for patients with lentigo maligna who prefer topical treatment to surgery or radiotherapy.

RESUMEN

Chronic ulcers represent a major health burden in our society. Despite many available therapies, a large number of ulcers do not heal. Protein based therapies fail in part due to proteolytic activity in the chronic wound bed. The aim of this in vitro study was to determine whether typical inflammatory cytokines and human salivary histatins remain stable when incubated with chronic wound extracts. Furthermore we determined whether a short exposure of histatins or cytokines was sufficient to exert long term effects on fibroblast migration. Stability of human recombinant cytokines IL-6 and CXCL8, and histatin variants (Hst1, Hst2, cyclic Hst1, minimal active domain of Hst1) in the presence of chronic wound extracts isolated from non-healing ulcers, was monitored by capillary zone electrophoresis. Migration-stimulating activity was assessed using a dermal fibroblast wound healing scratch assay. Histatins and cytokines stayed stable in saline for > 24 h at 37°C, making them ideal as an off-the-shelf product. However, incubation with chronic wound extracts resulted in serious breakdown of Hst1 and Hst2 (~50% in 8 h) and to lesser extent cyclic Hst1 and the minimal active domain of Hst1 (~20% in 8 h). The cytokines IL-6 and CXCL8 were more stable in chronic wound extracts (~40% degradation in 96 h). An initial 8-hour pulse of histatins or cytokines during a 96-hour study period was sufficient to stimulate fibroblast migration equally well as a continuous 96-hour exposure, indicating that they may possibly be used as novel bioactive therapeutics, exerting their activity for up to four days after a single exposure.

RESUMEN

Compression therapy and treating venous insufficiency is the standard of care for venous leg ulcers. The need for debridement on healing venous leg ulcers is still debated. Dressings are often used under compression bandages to promote faster healing and prevent adherence of the bandage to the ulcer. A wide range of dressings is available, including modern dressings with different kinds of biological activity. Microbial burden is believed to underlie delayed healing, but the exact role of microbiofilm in wound healing is uncertain. Before choosing a specific wound dressing, four main functions should be considered: (1) cleaning, (2) absorbing, (3) regulating or (4) the necessity of adding medication. There is no clear evidence to support the use of one dressing over another, as demonstrated by many Cochrane review studies. In addition, the prescriber should enquire about contact allergies that may also develop during wound treatment. It is shown that early intervention and early investment may reduce the cost of treatment. The choice of wound dressings should be guided by cost, ease of application and patient and physician preference and be part of the complete strategy. The role of the medical specialist is evident. Wound dressings matter as part of the optimal treatment in VLU patients.

RESUMEN

Chronic ulcers ((arterio)venous, decubitus, or postoperative) have no tendency to heal within a period of at least 3 months despite optimal therapy according to internationally accepted guidelines. This retrospective study evaluates the safety and efficacy of an autologous, dermal-epidermal skin substitute (SS) for treating ulcers of various origins. Ulcers were treated within 7 Dutch centers over 5 years. Sixty-six ulcers (size: 0.75-150 cm²; duration: 0.25-32 years) with a follow-up time of 24 weeks after a single-skin substitute application were assessed. Wound-bed preparation consisted of vacuum-assisted-closure-therapy (5 days, hospitalized) or application of acellular dermis (5-7 days, outpatient). Time to heal, adverse events, and recurrence 1 year after complete healing were recorded. Complete ulcer healing occurred in 36 of 66 ulcers (55%) at 24 weeks. At that time point, a further 29% of ulcers showed decrease in ulcer size between 50 and 99%. No difference was observed between the hospitalized vs. outpatient treatment with complete healing. There were 32 of 36 healed ulcers that were available for follow-up 1 year after complete closure, of which 27 (84%) were still closed. Only two minor/moderate possibly related adverse events were recorded. This retrospective analysis shows that SS provides a safe and successful treatment for particularly chronic ulcers of various origins.

RESUMEN

Non-healing venous leg ulcers are a cumbersome problem for the patient and the physician. Adequate compression therapy that reduces venous pressure is the cornerstone of treatment. For each patient treatment of superficial venous insufficiency should be considered. Adjuvant surgical, physical or biologic interventions can stimulate healing in case of refractory ulcers Treatment of a venous ulcer needs a tailored approach.

RESUMEN

A major challenge for clinicians treating (arterio) venous leg ulcers is to decide between standard therapy and advanced interventions. Here, we developed a simple method to collect human material representative of the ulcer wound bed, which can be used to identify biomarkers for prognostic test development. Superficial surgical debridement was performed using a small vidal curette during the weekly visit to the outpatient clinic. Moist, easily removable debridement material essentially blood free (including necrotic and nonviable slough) was collected from the surface of the ulcer. The amount ranged from 5.5 mg to 78 mg material per ulcer. Seventeen cytokines, chemokines, and growth factors were extracted and analyzed by enzyme-linked immunosorbent assay (concentration range: 0.0005-78 ng/mg total protein). Notably, CXCL8 was by far the most abundant protein present. Inflammatory mediators were more abundant than anti-inflammatory mediators (e.g., interleukin (IL)-10 and transforming growth factor-ß1). Bioactivity assays showed chronic wound extracts to be capable of stimulating fibroblast migration in a chemokine-dependent manner and also capable of stimulating healthy cells within skin substitutes to secrete wound healing mediators (CCL2, CXCL1, CXCL8, IL-6) in an IL-1α dependent manner. Collection of debridement tissue enables investigation of the ulcer environment in an easy noninvasive manner that may be suitable for prognostic test development.

RESUMEN

Scar formation is a physiologic reaction to dermal injury. We describe a 11-year-old girl and her 15-year-old cousin, who both presented with stellate scarlike lesions primarily located on the hands. Histopathologic examination confirmed scar tissue formation. There was no history of initiating trauma or other possible triggering factors. To our knowledge, this is the first reported case of spontaneous stellate scars in two young, second-degree family members, the exact pathogenesis of which remains to be elucidated.
