RESUMO

Abstract Chronic ulcers significantly affect the quality of life of patients and impose a high cost on the healthcare system. The therapeutic management should be comprehensive, taking into consideration the etiological diagnosis of the wound and the characteristics of the wound bed when deciding on a therapeutic proposal appropriate to the healing phase, correcting factors that delay healing. During the epithelialization phase, repair techniques with grafts are recommended to shorten re-epithelialization time, improve the quality of scar tissue, and achieve adequate pain management. Currently, due to the reported benefits of skin appendages, the technique of follicular unit auto-grafting obtained with a scalp punch is among the chosen strategies for wound repair. This is a minimally invasive, outpatient practice, whose technique has advantages over the donor site, patients recovery and well-being.

RESUMO

Introduction: Significant evidence suggests that plasma-rich in growth factors (PRGF) favor the repair of chronic wounds, enabling a rapid return to functionality. However, components of PRGF and their effects on persistent ulcers and epithelial tissues are not well characterized. The goals of this research were to analyze the biological properties of platelet-derived factors, to examine their effectiveness on healing of venous ulcers, and to establish a correlation with clinical and sociodemographic data. Methods: For the preparation of PRGF, the centrifugation technique was used, obtaining a 100 % autologous and biocompatible blood sample that was treated with sodium citrate and calcium chloride. The patients were attended weekly at the outpatient clinic for nursing consultation and wound dressing changes, with PRGF application every 15 days. The treatment protocols are described, and follow-up results are reported. Results: Initially, the patients' ulcers ranged in sizes from 4 to 84 cm2. After 12 weeks of treatment, there was a significant mean reduction of 46.2 % in ulcer area. At baseline, epithelial tissue was absent in all venous ulcers, but its presence grew significantly by the treatment period. However, the reduction of the area of the ulcers did not show significant correlation with the concentrations of the patient's growth factors. Conclusions: Using the established protocol for PRGF isolating, it was possible to obtain a product with the presence of the six growth factors related to tissue regeneration and observed a positive response on wound healing following treatment of venous ulcers, with capacity to accelerate re-epithelialization and restore the skin functional integrity.

RESUMO

INTRODUCTION/OBJECTIVE: Venous Leg Ulcers (VLU) present a challenging healing process. Attaining healing is a primary treatment objective, commonly pursued in Primary Health Care (PHC) or Specialist Wound Management Clinics. Our objective was to examine the association and interplay between sociodemographic, health, clinical, and care factors with the outcomes of VLU treatment in patients undergoing care at a Specialist Wound Management Clinic. METHODS: Longitudinal, observational study took place in a center for the treatment of chronic injuries linked to PHC. The sociodemographic aspects, health status and habits, clinical and care aspects of patients with VLU were scrutinized over a 1-year period. RESULTS: The sample comprised 103 participants, with some still under treatment (Treatment Group-TG/ n = 60) and others having achieved VLU healing (Healing Group-HG/ n = 43). An association between sociodemographic, health, clinical, and care factors and the healing outcome (HG) was identified. A moderate correlation was observed between factors predisposing to healing in the sociodemographic group and health habits. Notably, among sociodemographic factors, the older age group and improvements in health, particularly the reduced use of alcohol/smoking, appeared to exert the most significant influence on healing. Additionally, specialized service monitoring and the application of compression therapy were contributory factors. CONCLUSIONS: These findings substantiate the hypothesis that sociodemographic, health, clinical, and care-related aspects are intertwined with VLU healing. Protective factors associated with healing interacted synergistically, fostering a positive outcome over one year of treatment.

RESUMO

Objetivo: analizar el costo-efectividad y calcular la relación costoefectividad incremental del tratamiento multicapa compresivo con respecto al inelástico (bota de Unna y estiramiento corto) según la literatura actual. Método: estudio cuantitativo de costo-efectividad a través de un modelo con ayuda del software TreeAge® para la elaboración del árbol de decisión. Los supuestos anunciados se obtuvieron mediante el uso de datos secundarios de la literatura para estimar el costo y la efectividad de los parámetros asumidos. Para ello, se realizó una revisión sistemática de la literatura con metaanálisis. Resultados: el árbol de decisión, después del Roll Back, mostró que la terapia multicapa prevaleció sobre las alternativas en el caso base, presentó un costo intermedio por aplicación, pero obtuvo la mayor efectividad. El gráfico del análisis de costo-efectividad también demostró que había un dominio extendido de la bota de Unna sobre el vendaje de estiramiento corto. El análisis de sensibilidad reveló que el vendaje multicapa sigue siendo la alternativa con mayor costoefectividad, dentro del umbral de disposición a pagar. Conclusión: la alternativa con mayor costo-efectividad fue el vendaje multicapa, considerado estándar de oro en la literatura. La segunda alternativa con mayor costo-efectividad fue la bota de Unna, la terapia más utilizada en Brasil.

Objective: to analyze the cost-effectiveness and calculate the incremental cost-effectiveness ratio of multilayer compressive treatment in relation to inelastic (Unna boot and short stretch) therapy according to the current literature. Method: quantitative study about cost-effectiveness through modeling with the aid of TreeAge® software for construction of the decision tree. The anticipated assumptions were obtained by using secondary literature data to estimate the cost and effectiveness of the assumed parameters. A systematic literature review with meta-analysis was performed for this end. Results: the decision tree after Roll Back showed that the multilayer therapy dominated the alternatives in the base case, representing an intermediate cost per application, although with the highest effectiveness. The cost-effectiveness analysis graph also showed extended dominance of the Unna boot in relation to the short stretch bandage. The sensitivity analysis showed that multilayer bandage remains a more cost-effective alternative, within the threshold of willingness to pay. Conclusion: the most cost-effective alternative was multilayer bandage, considered the gold standard in the literature. The second most cost-effective alternative was the Unna boot, the most used therapy in Brazil.

RESUMO

Lower limb ulcers secondary to chronic venous disease (CVD) are a significant public health problem in Brazil and account for about 70% of these ulcers. Despite recent technological advances and the various therapeutic options for treatment of these chronic injuries, several factors may be involved in resistance to treatment. Dystrophic calcinosis cutis (DCC) is a rare and often underdiagnosed condition that, when in conjunction with CVD, may be associated with a refractory healing process. In this article, we report a case of DCC in a patient with CVD and discuss its etiology, pathophysiology and possible treatment options.

RESUMO

The aim of the study was to evaluate the healing process of chronic wounds treated with carboxymethylcellulose loaded with recombinant human epidermal growth factor in patients with diabetes. The case series consisted of 10 patients treated at the university hospital for 12 weeks. Data were analyzed using SPSS version 22.0. according to the intention to treat the principle, without the loss or exclusion of the participants. The sample consisted of 70% (7/10) males with a mean age of 61.9 years (±9.4); all (100%) had diabetes mellitus and 70% (7/10) had systolic hypertension associated with diabetes mellitus. Sixty percent (6/10) presented lesions of diabetic etiology and 40% (4/10) presented lesions of venous etiology; 70% (7/10) had had lesions for less than 5 years. The mean glycated hemoglobin was 7.8% (±2.7%), while the mean ankle-arm index (AAI) was 0.94 (±0.21). The mean initial area of all wounds was 13.4 cm², and the mean final area was 7.8 cm2, with a reduction rate of 28.9% over the 12 weeks of treatment. The reduction rate of diabetic ulcers was higher (33.4%) than that of venous ulcers (22.1%). Regarding the type of tissue, there was an increase in granulation and epithelialization, and a decrease in slough and the amount of exudate that were statistically significant (p = 0.021). No participant had severe or local adverse events during the study period. Epidermal growth factor was effective in the treatment of chronic wounds, especially diabetic ulcers, resulting in the reduction of the wound area and the improvement of tissue and exudate quality.

RESUMO

OBJECTIVE: The aim of the study was to phenotypically investigate the expression of the enzyme Klebsiella pneumoniae carbapenemase (KPC) in a Proteus mirabilis sample resistant to carbapenems, isolated from the wound of a patient with a venous leg ulcer (VLU) treated at an outpatient referral service. METHOD: This was a case study conducted with a patient who had a VLU on the lower left limb. Samples were taken for the examination of microbiological material from the patient's wound, using an aseptic technique. The colonies extracted were submitted to Gram staining and biochemical tests to identify the strain. In addition, an antimicrobial susceptibility test, E-test and a modified Hodge test were performed. RESULTS: The identified microorganism was Proteus mirabilis, which showed resistance to cefuroxime and the carbapenems imipenem and meropenem. As well as the minimum inhibitory concentration (MIC) of 3.0µg/ml for imipenem, demonstrating resistance, there was no KPC production by the tested isolate, which presented a negative modified Hodge test. CONCLUSION: The results highlight the importance of microbiological surveillance, aimed at reducing morbidity and mortality rates associated with infection by multiresistant bacteria.

Introduction: Venous ulcers are lesions developed mainly on the lower limbs. They cause continuous and disabling pain, impair mobility, alter self-image, and interfere with daily life activities. Venous ulcers are serious. They are caused by chronic venous insufficiency and permanent venous hypertension. People suffering from venous ulcers should receive comprehensive nursing care that contributes to self-care. Objective: To describe the strategies nursing professionals should consider for promoting self-care in people with venous ulcers. Method: Integrative review of the literature. Databases and electronic resources were searched: Medline using PubMed, Health, Epistemonikos, and SciELO. Research and review articles related to the study problem, published in English, Portuguese, or Spanish between 2010 and 2020, were included. This is a risk-free study, and copyrights were respected. Results: A sample of 41 publications was analyzed. The main themes derived from the analysis were the nursing care process and self-care, getting familiar with venous ulcers and therapeutic options, knowledge of compression therapy, and practice of healthy lifestyles. Conclusions: Nursing care for patients with venous ulcers should begin by recognizing a person from a holistic perspective and reciprocally with their environment. This approach implies a comprehensive care process that goes beyond the ulcer and values patients as active subjects of care so that they become familiar with their wounds and detect signs of improvement or warning. They can also know about compression therapy and therapeutic options and take the practice of healthy lifestyles into their daily lives.

RESUMO

Abstract Introduction Leg ulcers (LUs) are relatively common in patients with sickle cell anemia (SCA). The role of inflammation and nitric oxide (NO) pathways in the pathophysiology of the LU is not understood. Objective The aim of this study was to verify the association between inflammatory molecules and nitric oxide metabolites (NOx) and the occurrence of the LU in patients with SCA. Method It was a cross-sectional study on adult participants with SCA followed at Fundação Hemominas, a public blood center in Brazil. Eligible participants were recruited and included in one of two groups: Group 1, comprised of cases with SCA (Hb SS) and at least one LU at the time of inclusion in the study and Group 2, comprised of controls with SCA without a history of LU, matched by sex and age to cases. Participants were interviewed to obtain sociodemographic data and blood samples were collected. Clinical and laboratory data were abstracted from medical records. Nitric oxide metabolites (NOx) and inflammatory molecules were quantified using an immunoassay and Multiplex xMAP® technology, respectively. Eighty-seven individuals were included, ranging in age from 17 to 61 years (mean 40 ± 10.7 years); 30 had LU and 57 were controls without LU. Results Participants with LU had significantly higher levels of interleukin 8 (IL-8), IL-10, IL-15, NOx and platelet and white blood cell (WBC) counts, when compared to those without LU. Participants with LU had a significantly higher risk of having a history of osteomyelitis and a higher use of antiseptic soap in bathing, when compared to those without LU. Conclusion In conclusion, our results showed that NOx, inflammatory molecules and hematological features were associated with LU in Brazilian adults with SCA.

RESUMO

Sickle leg ulcers (SLU) are malleoli lesions with exuberant hemolytic pathophysiology. The microRNAs are potential genetic biomarkers for several pathologies. Thereby, we aimed to assess the expression of circulating miR-199a-5p, miR-144, and miR-126 in association with hemolytic biomarkers in SLU. This cross-sectional study included 69 patients with sickle cell disease, 52 patients without SLU (SLU-) and 17 patients with active SLU or previous history (SLU+). The results demonstrated elevated expression of circulating miR-199a-5p and miR-144 in SLU+ patients while miR-126 expression was reduced. Circulating miR-199a-5p and miR-144 were associated with hemolytic biomarkers such as LDH, indirect bilirubin, AST, GGT, iron, ferritin, RBC, hemoglobin, and NOm, in addition to association with impaired clinical profile of SLU. Furthermore, in silico analyses indicated interactions of miR-199a-5p with HIF1A, Ets-1, and TGFB2 genes, which are associated with vasculopathy and reduced NO. In contrast, miR-126 was associated with an attenuating clinical profile of SLU, in addition to not characterizing hemolysis. In summary, this study demonstrates, for the first time, that hemolytic mechanism in SLU can be characterized by circulating miR-199a-5p and miR-144. The circulating miR-126 may play a protective role in SLU. Thus, these microRNAs can support to establish prognosis and therapeutic strategy in SLU.

RESUMO

INTRODUCTION: Leg ulcers (LUs) are relatively common in patients with sickle cell anemia (SCA). The role of inflammation and nitric oxide (NO) pathways in the pathophysiology of the LU is not understood. OBJECTIVE: The aim of this study was to verify the association between inflammatory molecules and nitric oxide metabolites (NOx) and the occurrence of the LU in patients with SCA. METHOD: It was a cross-sectional study on adult participants with SCA followed at Fundação Hemominas, a public blood center in Brazil. Eligible participants were recruited and included in one of two groups: Group 1, comprised of cases with SCA (Hb SS) and at least one LU at the time of inclusion in the study and Group 2, comprised of controls with SCA without a history of LU, matched by sex and age to cases. Participants were interviewed to obtain sociodemographic data and blood samples were collected. Clinical and laboratory data were abstracted from medical records. Nitric oxide metabolites (NOx) and inflammatory molecules were quantified using an immunoassay and Multiplex xMAP® technology, respectively. Eighty-seven individuals were included, ranging in age from 17 to 61 years (mean 40 ±â€¯10.7 years); 30 had LU and 57 were controls without LU. RESULTS: Participants with LU had significantly higher levels of interleukin 8 (IL-8), IL-10, IL-15, NOx and platelet and white blood cell (WBC) counts, when compared to those without LU. Participants with LU had a significantly higher risk of having a history of osteomyelitis and a higher use of antiseptic soap in bathing, when compared to those without LU. CONCLUSION: In conclusion, our results showed that NOx, inflammatory molecules and hematological features were associated with LU in Brazilian adults with SCA.

RESUMO

Resumo As úlceras de membros inferiores, secundárias à doença venosa crônica (DVC), constituem um problema significativo de saúde pública no Brasil e representam cerca de 70% do total dessas úlceras. Apesar dos recentes avanços tecnológicos e das diversas opções terapêuticas utilizadas para essas lesões crônicas, existem diversos fatores que podem estar implicados na resistência ao tratamento. A calcificação distrófica cutânea (CDC) é uma condição rara e frequentemente subdiagnosticada, que, quando associada à DVC, pode estar associada à refratariedade no processo cicatricial. Neste artigo, relatamos um caso de CDC em paciente portador de DVC e discutimos a sua etiologia, fisiopatologia e possíveis opções de tratamento.

Abstract Lower limb ulcers secondary to chronic venous disease (CVD) are a significant public health problem in Brazil and account for about 70% of these ulcers. Despite recent technological advances and the various therapeutic options for treatment of these chronic injuries, several factors may be involved in resistance to treatment. Dystrophic calcinosis cutis (DCC) is a rare and often underdiagnosed condition that, when in conjunction with CVD, may be associated with a refractory healing process. In this article, we report a case of DCC in a patient with CVD and discuss its etiology, pathophysiology and possible treatment options.

RESUMO

ABSTRACT Objective: To evaluate the presence of anemia in patients with chronic lower limb ulcers based on profile and hematometric indices. Method: This is a cross-sectional study carried out in a university hospital in Rio de Janeiro. The sample was composed of 64 participants with lower limb ulcers and evolution time greater than 12 weeks. Data was collected between May/2016 and December/2017 from hematological analyses, records from medical records, and wound assessment form. Results: 36 (56.2%) were male; 38 (59.4%) between 60 and 80 years old; 56 (87.5%) with chronic diseases and 52 (81.2%) with venous ulcers. 6 years mean of active ulceration. Anemia was detected in 36 (56.2%), 27 (75%) of which were normochromic and normocytic; 14 (38.8%) had deficiency anemia recorded in their medical chart. Conclusion: The low hemoglobin concentration is recurrent among the participants characterizing an anemia condition, whose profile reveals congruence to the anemia of chronic disease.

RESUMO

ABSTRACT Objective: To understand the experience of a woman with systemic lupus erythematosus and leg ulcers with cutaneous calcinosis. Methods: An experience report based on the social phenomenology of Alfred Schutz, conducted with a young woman undergoing treatment in an outpatient service. Results: The disease manifested itself in adolescence and brought emotional instability associated with body image concern and social isolation. The discontinuation of the studies triggered financial limitations with implications for treatment. The presence of ulcers aggravated by skin calcification makes the process of getting sick tiring and painful. Interpersonal relationships are resources for coping with situations experienced. Final considerations: Patients with lupus may have social, affective, and family life, even in the face of the limitations imposed by the disease. However, the emergence of leg ulcer with calcinosis changes this situation.

RESUMEN Objetivo: Comprender la experiencia de una mujer con lupus eritematoso sistémico y úlceras de la pierna con calcinosis cutis. Métodos: Relato de experiencia amparado en la fenomenología social de Alfred Schutz, realizado con una joven en tratamiento en un servicio ambulatorio. Resultados: La enfermedad se ha manifestado en la adolescencia y trajo inestabilidad emocional relacionada a la preocupación con la imagen corporal y aislamiento social. La interrupción de los estudios desencadenó limitaciones financieras con implicaciones para el tratamiento. La presencia de úlceras agravada por la calcificación cutánea vuelve el proceso de enfermedad cansado y doloroso. Las relaciones interpersonales son recursos para el enfrentamiento de las situaciones vividas. Consideraciones finales: Es posible que pacientes con lupus puedan tener vida social, afectiva y familiar, mismo delante de las limitaciones impuestas por la enfermedad, entretanto el surgimiento de la úlcera de la pierna con calcinosis altera esa situación.

RESUMO Objetivo: Compreender a experiência de uma mulher com lúpus eritematoso sistêmico e úlceras da perna com calcinose cutânea. Métodos: Relato de experiência amparado na fenomenologia social de Alfred Schutz, realizado com uma jovem em tratamento em um serviço ambulatorial. Resultados: A doença manifestou-se na adolescência e trouxe instabilidade emocional associada à preocupação com a imagem corporal e isolamento social. A interrupção dos estudos desencadeou limitações financeiras com implicações para o tratamento. A presença de úlceras agravada pela calcificação cutânea torna o processo de adoecimento cansativo e doloroso. As relações interpessoais são recursos para o enfrentamento das situações vividas. Considerações finais: Épossível que pacientes com lúpus possam ter vida social, afetiva e familiar, mesmo diante das limitações impostas pela doença, entretanto o surgimento da úlcera da perna com calcinose altera essa situação.
