RESUMO
ABSTRACT Introduction: Lung diseases are common in patients with end stage kidney disease (ESKD), making differential diagnosis with COVID-19 a challenge. This study describes pulmonary chest tomography (CT) findings in hospitalized ESKD patients on renal replacement therapy (RRT) with clinical suspicion of COVID-19. Methods: ESKD individuals referred to emergency department older than 18 years with clinical suspicion of COVID-19 were recruited. Epidemiological baseline clinical information was extracted from electronic health records. Pulmonary CT was classified as typical, indeterminate, atypical or negative. We then compared the CT findings of positive and negative COVID-19 patients. Results: We recruited 109 patients (62.3% COVID-19-positive) between March and December 2020, mean age 60 ± 12.5 years, 43% female. The most common etiology of ESKD was diabetes. Median time on dialysis was 36 months, interquartile range = 12-84. The most common pulmonary lesion on CT was ground glass opacities. Typical CT pattern was more common in COVID-19 patients (40 (61%) vs 0 (0%) in non-COVID-19 patients, p < 0.001). Sensitivity was 60.61% (40/66) and specificity was 100% (40/40). Positive predictive value and negative predictive value were 100% and 62.3%, respectively. Atypical CT pattern was more frequent in COVID-19-negative patients (9 (14%) vs 24 (56%) in COVID-19-positive, p < 0.001), while the indeterminate pattern was similar in both groups (13 (20%) vs 6 (14%), p = 0.606), and negative pattern was more common in COVID-19-negative patients (4 (6%) vs 12 (28%), p = 0.002). Conclusions: In hospitalized ESKD patients on RRT, atypical chest CT pattern cannot adequately rule out the diagnosis of COVID-19.
RESUMO Introdução: Doenças pulmonares são comuns em pacientes com doença renal em estágio terminal (DRET), dificultando o diagnóstico diferencial com COVID-19. Este estudo descreve achados de tomografia computadorizada de tórax (TC) em pacientes com DRET em terapia renal substitutiva (TRS) hospitalizados com suspeita de COVID-19. Métodos: Indivíduos maiores de 18 anos com DRET, encaminhados ao pronto-socorro com suspeita de COVID-19 foram incluídos. Dados clínicos e epidemiológicos foram extraídos de registros eletrônicos de saúde. A TC foi classificada como típica, indeterminada, atípica, negativa. Comparamos achados tomográficos de pacientes com COVID-19 positivos e negativos. Resultados: Recrutamos 109 pacientes (62,3% COVID-19-positivos) entre março e dezembro de 2020, idade média de 60 ± 12,5 anos, 43% mulheres. A etiologia mais comum da DRET foi diabetes. Tempo médio em diálise foi 36 meses, intervalo interquartil = 12-84. A lesão pulmonar mais comum foi opacidades em vidro fosco. O padrão típico de TC foi mais comum em pacientes com COVID-19 (40 (61%) vs. 0 (0%) em pacientes sem COVID-19, p < 0,001). Sensibilidade 60,61% (40/66), especificidade 100% (40/40). Valores preditivos positivos e negativos foram 100% e 62,3%, respectivamente. Padrão atípico de TC foi mais frequente em pacientes COVID-19-negativos (9 (14%) vs. 24 (56%) em COVID-19-positivos, p < 0,001), enquanto padrão indeterminado foi semelhante em ambos os grupos (13 (20%) vs. 6 (14%), p = 0,606), e padrão negativo foi mais comum em pacientes COVID-19-negativos (4 (6%) vs. 12 (28%), p = 0,002). Conclusões: Em pacientes com DRET em TRS hospitalizados, um padrão atípico de TC de tórax não pode excluir adequadamente o diagnóstico de COVID-19.
RESUMO
ABSTRACT Introduction: The importance of dietitians in dialysis units is indisputable and mandatory in Brazil, but little is known about the practices adopted by these professionals. Objective: To know practices adopted in routine nutritional care, focusing on nutritional assessment tools and treatment strategies for people at risk or diagnosed with malnutrition. Methodology: Electronic questionnaire disseminated on social media and messaging applications. It included questions that covered dietitians' demographic and occupational profile characteristics and of the dialysis unit, use and frequency of nutritional assessment tools, nutritional intervention strategies in cases of risk or diagnosis of malnutrition, prescription and access to oral supplements. Results: Twenty four percent of the Brazilian dialysis units (n = 207) responded electronically. The most used nutritional assessment tools with or without a pre-established frequency were dietary surveys (96%) and Subjective Global Assessment (83%). The strategies in cases of risk or presence of malnutrition used most frequently (almost always/always) were instructions to increase energy and protein intake from foods (97%), and increasing the frequency of visits (88%). The frequency of prescribing commercial supplements with standard and specialized formulas was quite similar. The availability of dietary supplements by the public healthcare system to patients varied between regions. Conclusion: Most dietitians use various nutritional assessment tools and intervention strategies in cases of risk or malnutrition; however, the frequency of use of such tools and strategies varied substantially.
Resumo Introdução: A importância da atuação do nutricionista em unidades de diálise é indiscutível e obrigatória no Brasil, porém pouco sabemos sobre as práticas adotadas por esses profissionais. Objetivo: Conhecer práticas adotadas na rotina dos atendimentos nutricionais, com foco nas ferramentas de avaliação nutricional e nas estratégias de tratamento das pessoas com risco ou diagnóstico de desnutrição. Metodologia: Questionário eletrônico divulgado em mídias sociais e aplicativos de mensagens. Incluiu questões que abrangiam características do perfil demográfico e ocupacional do profissional e da unidade de diálise, utilização e frequência de ferramentas de avaliação nutricional, estratégias de intervenção nutricional em casos de risco ou diagnóstico de desnutrição e prescrição e acesso a suplementos alimentares orais. Resultados: Foram recebidos eletronicamente o equivalente a 24% das unidades de diálise brasileiras (n = 207). As ferramentas de avaliação nutricional mais utilizadas com ou sem frequência pré-estabelecida foram inquéritos dietéticos (96%) e Avaliação Global Subjetiva (83%). As estratégias em casos de risco ou presença de desnutrição utilizadas com mais frequência (quase sempre/sempre) foram a orientação de incremento energético e proteico por meio de alimentos (97%) e o aumento da periodicidade das visitas (88%). A frequência de prescrição de suplemento industrializado de fórmula padrão e especializada foi bastante semelhante. A disponibilização de suplementos alimentares pelo Sistema Único de Saúde aos pacientes variou entre as regiões. Conclusão: A maior parte dos nutricionistas utiliza diversas ferramentas de avaliação nutricional e estratégias de intervenção em casos de risco ou desnutrição, porém a frequência de utilização de tais ferramentas e estratégias foi bastante variada.
RESUMO
Introduction: Patients with end-stage renal disease (ESRD) frequently change renal replacement (RRT) therapy modality due to medical or social reasons. We aimed to evaluate the outcomes of patients under peritoneal dialysis (PD) according to the preceding RRT modality. Methods: We conducted a retrospective observational single-center study in prevalent PD patients from January 1, 2010, to December 31, 2017, who were followed for 60 months or until they dropped out of PD. Patients were divided into three groups according to the preceding RRT: prior hemodialysis (HD), failed kidney transplant (KT), and PD-first. Results: Among 152 patients, 115 were PD-first, 22 transitioned from HD, and 15 from a failing KT. There was a tendency for ultrafiltration failure to occur more in patients transitioning from HD (27.3% vs. 9.6% vs. 6.7%, p = 0.07). Residual renal function was better preserved in the group with no prior RRT (p < 0.001). A tendency towards a higher annual rate of peritonitis was observed in the prior KT group (0.70 peritonitis/year per patient vs. 0.10 vs. 0.21, p = 0.065). Thirteen patients (8.6%) had a major cardiovascular event, 5 of those had been transferred from a failing KT (p = 0.004). There were no differences between PD-first, prior KT, and prior HD in terms of death and technique survival (p = 0.195 and p = 0.917, respectively) and PD efficacy was adequate in all groups. Conclusions: PD is a suitable option for ESRD patients regardless of the previous RRT and should be offered to patients according to their clinical and social status and preferences.
Introdução: Pacientes com doença renal em estágio terminal (DRET) frequentemente mudam de modalidade de terapia renal substitutiva (TRS) por razões médicas ou sociais. Nosso objetivo foi avaliar desfechos de pacientes em diálise peritoneal (DP) segundo a modalidade anterior de TRS. Métodos: Realizamos estudo retrospectivo observacional unicêntrico, em pacientes prevalentes em DP, de 1º de janeiro de 2010 a 31 de dezembro de 2017, acompanhados por 60 meses ou até saírem de DP. Pacientes foram divididos em três grupos de acordo com a TRS anterior: hemodiálise prévia (HD), transplante renal malsucedido (TR) e DP como primeira opção (PD-first). Resultados: Entre 152 pacientes, 115 eram PD-first, 22 transitaram da HD e 15 de TR malsucedido. Houve tendência à maior ocorrência de falência de ultrafiltração em pacientes em transição da HD (27,3% vs. 9,6% vs. 6,7%; p = 0,07). A função renal residual foi melhor preservada no grupo sem TRS prévia (p < 0,001). Observou-se tendência à maior taxa anual de peritonite no grupo TR prévio (0,70 peritonite/ano por paciente vs. 0,10 vs. 0,21; p = 0,065). Treze pacientes (8,6%) tiveram um evento cardiovascular maior, cinco dos quais haviam sido transferidos de um TR malsucedido (p = 0,004). Não houve diferenças entre PD-first, TR prévio e HD prévia em termos de óbito e sobrevida da técnica (p = 0,195 e p = 0,917, respectivamente) e a eficácia da DP foi adequada em todos os grupos. Conclusões: A DP é uma opção adequada para pacientes com DRET, independentemente da TRS anterior, e deve ser oferecida aos pacientes de acordo com seu status clínico e social e suas preferências.
RESUMO
Background: Anemia is prevalent among patients with cardiovascular disease and is associated with adverse outcomes. However, data regarding the impact of anemia in high-risk percutaneous coronary intervention (HRPCI) are limited. Objectives: This study aimed to evaluate the impact of anemia in patients undergoing Impella-supported HRPCI in the PROTECT III study. Methods: Patients undergoing Impella-supported HRPCI in the multicenter PROTECT III study were assessed for anemia based on baseline hemoglobin levels according to World Health Organization criteria. Patients were stratified into three groups, namely, no anemia, mild anemia, and moderate or severe anemia. Major adverse cardiovascular and cerebrovascular events (MACCE: all-cause death, myocardial infarction, stroke/transient ischemic attack, and repeat revascularization) at 30 and 90 days, and major bleeding events were compared across groups. Results: Of 1,071 patients with baseline hemoglobin data, 37.9% had no anemia, 43.4% had mild anemia, and 18.7% had moderate or severe anemia. Anemic patients were older and more likely to have comorbidities. Anemia was associated with higher MACCE rates at 30 days (moderate to severe, 12.3%; mild, 9.8%; no anemia, 5.4%; p = 0.02) and at 90 days (moderate to severe, 18.7%; mild, 14.6%; none, 8.3%; p = 0.004). These differences persisted after adjustment for potential confounders at 30 and 90 days, and sensitivity analysis excluding dialysis showed similar results. Major bleeding at 30 days was also higher in anemic patients (5.5% vs. 1.2%, p = 0.002). Conclusion: Baseline anemia in Impella-supported HRPCI is common and independently associated with MACCE and major bleeding, emphasizing its significance as a prognostic factor. Specific management strategies to reduce anemia-associated MACCE risk after HRPCI should be examined.

RESUMO
Background: Catheter malfunction is a common problem following the placement of a peritoneal dialysis (PD) catheter, and it is characterized by inadequate dialysate drainage, which can also limit infusion. Common causes include constipation, catheter migration, catheter kinking, omental wrapping, and fibrin obstruction. However, catheter obstruction by other intra-abdominal organs has been observed infrequently. Case Description: We present two cases of female PD patients experiencing catheter dysfunction after catheter implantation. The first case involves a 28-year-old female who suffered from problematic drainage and infusion of dialysate 1 month after catheter insertion, evidenced by catheter displacement from the pelvis on abdominal X-ray. The second case concerns a 49-year-old female PD patient who also encountered a bidirectional catheter malfunction 40 days post-implantation. Conservative methods failed to restore the catheter function in both patients. Laparoscopic examination revealed fallopian tube, not the omentum, was tightly wrapped around the PD catheter in both cases. Finally, laparoscopic surgery with catheter fixation restored the catheter function, enabling continued continuous ambulatory peritoneal dialysis (CAPD) with favorable outcomes. Conclusions: Our findings indicate that healthcare providers should consider fallopian tube wrapping as a potential cause of catheter dysfunction. Prompt consideration and utilization of laparoscopy with catheter fixation can play an important role in restoring catheter function and improving patient outcomes.
RESUMO
Background: Living with kidney failure can interfere with life participation (ie, participation in valued life activities). Life participation has recently been identified as a top-priority health outcome of people on peritoneal dialysis therapy, but it is a relatively unexplored topic in peritoneal dialysis. Objective: The objective is to describe the interventions that have been used to promote life participation in the peritoneal dialysis population and highlight research gaps warranting further investigation. Design: A scoping review was conducted according to the Joanna Briggs Institute methodology. Setting: Six electronic databases (MEDLINE [OVID], EMBASE, PsycINFO, Cochrane Central Register of Controlled Trials, CINAHL Plus, SCOPUS) were searched. Patients: Adults aged 18+ years on peritoneal dialysis therapy. Measurements: Any dedicated scale or subscale that measured life participation as an isolated outcome. Methods: Title/abstract screening was completed independently after adequate inter-rater reliability (kappa > 0.8) was achieved among reviewers. Full-text review and data extraction were conducted in duplicate. Extracted data were analyzed using counts, percentages, and narrative synthesis to describe patterns in the literature. Results: After identifying 13 874 results, 17 studies met eligibility criteria. Eight studies were conducted within the past 5 years, with China as the most common study location. Only 2 studies investigated life participation as a primary study outcome. Eight studies targeted personal-physical barriers to life participation, 8 targeted multiple barriers, and 1 targeted an environmental-institutional barrier. Life participation was assessed within a subdomain of a broader quality of life assessment (The Kidney Disease Quality of Life [KDQOL]-36 or the 36-Item Short-Form Health Survey [SF-36]) in 11 studies. The majority of assessments captured life participation in all major domains of participation (self-care, work, and leisure). Limitations: Eligibility screening at title/abstract stage was not performed in duplicate; articles not available in English were excluded. Conclusions: Life participation has infrequently been prioritized as a health outcome in peritoneal dialysis (PD). Interventions have been narrow in focus given the range of challenges faced by people on PD and the holistic approaches used in other clinical populations. Future research should prioritize life participation as a key health outcome in PD and investigate the impact of interventions that address cognitive, affective, and environmental barriers to participation.
Contexte: Vivre avec l'insuffisance rénale peut entraver la participation à la vie (c.-à-d., la participation aux activités significatives du quotidien). La participation à la vie a récemment été identifiée comme un résultat de santé prioritaire pour les personnes sous dialyse péritonéale. Pourtant, elle demeure un sujet relativement inexploré en contexte de dialyse péritonéale (DP). Objectifs: Décrire les interventions utilisées pour promouvoir la participation à la vie dans une population sous dialyse péritonéale et mettre en évidence les lacunes de la recherche qui justifieraient une étude plus approfondie. Conception: Un examen de la portée a été effectué selon la méthodologie de l'Institut Joanna Briggs. Sources: Consultation de six bases de données électroniques (MEDLINE [OVID], embase, PsycINFO, Cochrane Central Register of Controlled Trials, CINAHL plus et SCOPUS). Sujets: Des adultes (18 ans et plus) sous dialyse péritonéale. Mesures: Toute échelle ou sous-échelle dédiée mesurant la participation à la vie comme un résultat isolé. Méthodologie: La sélection du titre ou du résumé des articles a été effectuée de façon indépendante une fois la valeur adéquate de fiabilité inter-évaluateurs (kappa > 0,8) atteinte parmi les évaluateurs. L'examen du texte intégral et l'extraction des données ont été effectués en double. L'analyse des données extraites a été réalisée à l'aide de dénombrements, de pourcentages et de synthèses narratives afin de décrire les tendances dans la littérature. Résultats: Des 13 874 résultats répertoriés, seules 17 études répondaient aux critères d'admissibilité. Huit études avaient été menées dans les cinq dernières années, le plus souvent en Chine. Seules deux études avaient examiné la participation à la vie comme critère de jugement principal. Huit études ciblaient les obstacles personnels-physiques à la participation à la vie, huit ciblaient les obstacles multiples et une seule ciblait les obstacles environnementaux-institutionnels. La participation à la vie avait été évaluée dans un sous-domaine d'une évaluation plus large de la qualité de vie (KDQOL-36 ou SF-36) dans onze des études retenues. La majorité des évaluations portaient sur la participation à la vie dans tous les domaines principaux (soins personnels, travail et loisirs). Limites: La vérification de l'admissibilité à l'étape de la sélection des titres ou résumés n'a pas été effectuée en double; les articles non disponibles en anglais ont été exclus. Conclusion: La participation à la vie a rarement été considérée comme un résultat de santé prioritaire en DP. Les interventions ont été limitées, compte tenu de l'éventail des défis auxquels sont confrontées les personnes sous DP et des approches holistiques utilisées dans d'autres populations cliniques. Les recherches futures devraient accorder la priorité à la participation à la vie comme résultat clé de la santé des personnes sous DP et étudier l'effet des interventions qui s'attaquent aux obstacles cognitifs, affectifs et environnementaux qui entravent la participation à la vie.
RESUMO
Post-dialysis fever is commonly reported in patients undergoing hemodialysis (HD). However, it is often challenging to identify the underlying cause owing to the wide variety of potential factors that can lead to fever. In this case, a 66-year-old Japanese man experienced recurrent fever after HD treatment. Initially, antibiotics were prescribed to treat pneumonia, but it was later discovered that the pneumonia was an alveolar hemorrhage caused by cryoglobulinemic vasculitis. It is believed that cryoglobulin was sensitized by cold exposure owing to the dialysate temperature, which resulted in fever being experienced only after HD. Although treatment for vasculitis required prednisolone and rituximab, simple plasma exchange and a dialysate temperature of 37.5 °C dramatically suppressed the occurrence of post-dialysis fever. Cryoglobulinemia should be considered as a potential cause of fever, as it may be a common occurrence in patients undergoing HD and could be overlooked as a possible cause of localized fever following HD treatment.
RESUMO
Peritoneal dialysis (PD)-associated peritonitis is a major cause of peritoneal dysfunction and failure. The main issue regarding the treatment is whether to remove the catheter surgically or to treat with antibiotics alone. Notably, PD-associated peritonitis is commonly caused by gram-positive cocci, but rarely by Listeria monocytogenes and Burkholderia cepacia. Here, we report a patient diagnosed with PD-associated peritonitis caused by L. monocytogenes and B. cepacia who presented with a fever, abdominal pain, and turbid dialysate and had been receiving PD for over 20 years. After 2 weeks of antibiotic treatment, the catheter in the patient was surgically removed. Culture and pathology results revealed pathogen growth, foreign body granuloma with chronic inflammation, and inflammatory cells with fibroblast infiltration. The patient was switched to hemodialysis. She eventually recovered and was discharged. The patient presented fair health at the 3-month follow-up. In conclusion, sequential dialysate white blood cell count may help clinicians decide the course of treatment and guide the timing of surgical intervention.
RESUMO
BACKGROUND: Gastrointestinal symptoms are common in patients with uremia undergoing hemodialysis, and these symptoms seriously affect patients' prognosis. AIM: To assess the occurrence and factors influencing gastrointestinal symptoms in patients with uremia undergoing hemodialysis. METHODS: We retrospectively selected 98 patients with uremia who underwent regular hemodialysis treatment in the blood purification center of our hospital from December 2022 to December 2023. The gastrointestinal symptoms and scores of each dimension were evaluated using the Gastrointestinal Symptom Grading Scale (GSRS). Patients were divided into gastrointestinal symptoms and no gastrointestinal symptom groups according to whether they had gastrointestinal symptoms. The factors that may affect gastrointestinal symptoms were identified by single-factor analysis. Multiple logistic regression analysis was performed to identify independent risk factors for gastrointestinal symptoms. RESULTS: Gastrointestinal symptoms included indigestion, constipation, reflux, diarrhea, abdominal pain, and eating disorders, and the total average GSRS score was 1.35 ± 0.47. This study showed that age, number of tablets, dialysis time, glucocorticoid, parathyroid hormone (PTH), combined diabetes mellitus and C-reactive protein (CRP) were independent risk factors for gastrointestinal symptoms in patients with uremia undergoing hemodialysis, whereas body mass index (BMI), hemoglobin (Hb), and urea clearance index were independent protective factors (P < 0.05). CONCLUSION: Gastrointestinal symptoms are mostly mild in patients with uremia undergoing hemodialysis, most commonly including dyspepsia, eating disorders, and gastroesophageal reflux. The independent influencing factors mainly include the BMI, age, number of pills taken, dialysis time, urea clearance index, Hb, use of glucocorticoids, and thyroid hormone level. PTH, CRP, and diabetes are clinically related factors influencing the occurrence of gastrointestinal symptoms, and targeted prevention can be performed.
RESUMO
BACKGROUND: Radio-cephalic arteriovenous fistulas (RC-AVFs), the preferred vascular access for hemodialysis, have high failure rates. New techniques like the no-touch technique (NTT) and modified no-touch technique (MNTT) have shown promising results. Our objective is to highlight the effectiveness of non-conventional techniques, aiming to address the challenge of AVF failure. METHODS: We searched Medline, Google Scholar, and Clinicaltrials.gov until April 2023, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Five relevant articles were found, all involving human studies on NTT or MNTT for RC-AVF creation. We focused on primary and secondary patency rates, fistula maturation rates, and complications. RESULTS: We reviewed five studies: two pilot, two prospective, and one retrospective. Three used NTT, and two used MNTT. Among double-arm studies, three out of four showed a significantly improved primary patency with non-conventional techniques. However, one study found no significant difference between non-conventional and conventional methods (90.5% vs. 84.2%; p=0.225). In a single-arm study, non-conventional technique (NTT) displayed 54% primary patency at one year. Secondary patency rates were in three studies. One demonstrated significant secondary patency with non-conventional methods compared to conventional (90% vs. 67.5%; p=0.028), while another found no significant difference (90.5% vs. 84.2%; p=0.803). In the single-arm study, the non-conventional technique (NTT) revealed 80% secondary patency at one year. CONCLUSION: Non-conventional techniques (NTT and MNTT) show promise in improving patency rates, hinting at their potential as alternatives to the conventional technique for RC-AVF creation. Further studies are crucial to confirm their effectiveness and evaluate long-term outcomes.
RESUMO
Central venous access devices are essential for the management of critically ill patients, but they are potentially associated with many complications, which may occur during or after insertion. Many evidence-based documents-consensus and guidelines-suggest practical recommendations for reducing catheter-related complications, but they have some limitations. Some documents are not focused on critically ill patients; other documents address only some special strategies, such as the use of ultrasound; other documents are biased by obsolete concepts, inappropriate terminology, and lack of considerations for new technologies and new methods. Thus, the Italian Group of Venous Access Devices (GAVeCeLT) has decided to offer an updated compendium of the main strategies-old and new-that should be adopted for minimizing catheter-related complications in the adult critically ill patient. The project has been planned as a consensus, rather than a guideline, since many issues in this field are relatively recent, and few high-quality randomized clinical studies are currently available, particularly in the area of indications and choice of the device. Panelists were chosen between the Italian vascular access experts who had published papers on peer-reviewed journals about this topic in the last few years. The consensus process was carried out according to the RAND/University of California at Los Angeles (UCLA) Appropriateness Methodology, a modification of the Delphi method, that is, a structured process for collecting knowledge from groups of experts through a series of questionnaires. The final document has been structured as statements which answer to four major sets of questions regarding central venous access in the critically ill: (1) before insertion (seven questions), (2) during insertion (eight questions), (3) after insertion (three questions), and (4) at removal (three questions).
RESUMO
A 25-year-old female patient with chronic glomerulonephritis, initiated on haemodialysis presented with high-grade fever, a dysfunctional catheter, low oxygen saturation and unstable blood pressure. Upon evaluation, the patient was febrile with elevated white blood cell counts. She was intubated, started on inotropes and transferred to the intensive care unit. Chest radiography showed that the tunnelled internal jugular dialysis catheter had migrated to the inferior vena cava. Echocardiography and transoesophageal echocardiography showed severe heart dysfunction with a large thrombus attached to the catheter, indicating catheter-related atrial thrombus (CRAT). CT pulmonary angiography revealed blockage of the segmental pulmonary arteries, suggesting pulmonary embolism. Blood and tracheal cultures revealed Methicillin-resistant Staphylococcus aureus (MRSA). The patient was administered appropriate antibiotics and anticoagulants and underwent surgical removal of the thrombus and the catheter. This case demonstrates the risks associated with improper placement of dialysis catheters and highlights the brief management of CRAT.
RESUMO
Background: While most infections with multidrug-resistant organisms (MDROs) affect colonised people, there is limited evidence on MDRO colonisation in South African dialysis patients. Objectives: This study evaluated the prevalence of MDRO colonisation among dialysis patients, the resistance patterns of each MDRO and the risk factors for colonisation. Method: Rectal and nasal swabs were collected from dialysis patients who consented to participate in a 5-month study to identify selected MDROs (April 2021 - August 2021). Specimens were cultured on selected chromogenic media. Data collected included demographics, clinical information from medical records and laboratory results. Results: Multidrug-resistant organisms were isolated from 17 (23.9%) of the 71 enrolled participants. Of the 23 MDRO strains from rectal swabs (n = 71), extended-spectrum beta-lactamase-producing Enterobacterales accounted for 21.1% (15/71), vancomycin-resistant enterococci 2.8% (n = 2/71) and carbapenem-resistant Enterobacterales 4.2% (n = 3/71). Klebsiella pneumoniae (65.2%, n = 15/23) was the most prevalent MDRO. More than 80% resistance to trimethoprim and sulfamethoxazole, cefotaxine, and ciprofloxacin was noted. Significant risk factors included previous hospitalisation, proton pump inhibitor use and antibiotic exposure in the past 6 months. Conclusion: Multidrug-resistant organisms' carriage was high in our dialysis population. The infection prevention and control measures need to be revised and strengthened. Contribution: This study falls within the scope of the SAJID journal as it is the first within sub-Sahara Africa to report that approximately one-fifth of dialysis patients were colonised with MDRO, which is a significant risk for MDRO infections.
RESUMO
Background. People with kidney failure who undergo hemodialysis treatment and experience chronic fatigue identify negative effects on occupational performance and participation as a key aspect of their illness experience. Purpose. To describe the occupational performance and participation problems of people treated with hemodialysis who live with debilitating fatigue. Method. Fifteen participants, who were randomized to participate in an energy management intervention as part of a randomized controlled trial, completed two occupation-based assessments at baseline and chose three priority occupational performance or participation problems to address as goals during the intervention. Results were analyzed using descriptive statistics (counts and percentages). Findings. Fifteen participants (mean age 60, 53% male) completed the occupation-based assessments. Participants stated that they wanted or needed more energy for a median of 22 of 55 occupations. Going out for food/drinks (n = 11), going to a movie/concert/performance (n = 10), and food preparation/clean-up (n = 10) were the top occupations for which participants required more energy. Prioritized occupational performance and participation problems most often fell within the household management (14 goals), self-care (6 goals), and hobbies (5 goals) domains. Conclusion. Occupational performance and participation problems are extensive among people treated with hemodialysis who live with debilitating fatigue. There is a clear need for occupation-based interventions that optimize occupational performance and participation in this population.
RESUMO
Peritoneal dialysis (PD) is a vital treatment modality for renal failure patients, facilitating the removal of excess fluid and unwanted substances. However, peritonitis, a significant complication experienced by PD patients, necessitates careful selection of antibiotics to ensure successful treatment. Commonly used antibiotics in PD patients, such as cephalosporins and glycopeptides like vancomycin, have been associated with undesirable side effects and high failure rates. In response to these challenges, teicoplanin, a novel glycopeptide antibiotic, has gained attention due to its similar range of activity to vancomycin, extended half-life, reduced side effects, and improved elimination. The objective of this study is to comprehensively review the efficacy, mechanism of action, adverse effects, and pharmacological benefits of teicoplanin in peritoneal dialysis patients. Our research involved an extensive review of 21 articles from reputable databases, including Google Scholar, PubMed, and ScienceDirect. The data extracted from these studies was meticulously evaluated to comprehensively understand teicoplanin's clinical profile in this specific patient population. Major findings of these studies are that glycopeptide-based regimens have higher cure rates over first-generation cephalosporins or fluoroquinolones, and teicoplanin demonstrated several advantages over vancomycin, such as a higher therapeutic index, good tolerance, longer half-life, lower rates of nephrotoxicity, improved elimination while being equally effective. Teicoplanin is typically administered to peritoneal dialysis patients with a loading dose of 400 mg, aiming to achieve a trough concentration of 10-15 mg/dl. Teicoplanin's improved tolerability and lack of regular serum level monitoring requirements make it a promising alternative to traditional antibiotics for clinical use.
RESUMO
Cytomegalovirus (CMV) infection is widespread in immunocompromised people, and several cases of CMV infections of the gastrointestinal (GI) tract have been reported in these individuals. We present a case of an immunocompetent patient on hemodialysis (HD) who developed CMV colitis. We also conducted a review of the literature on CMV GI tract infections among patients with chronic kidney disease undergoing dialysis. A 46-year-old man with a history of end-stage renal disease and undergoing HD developed severe diarrhea and hematochezia. A colonoscopy revealed ulcers, and CMV infection was identified in the biopsy sample. We successfully treated the patient with valganciclovir for 2 months. Our review of the literature yielded 21 articles and 24 cases of CMV GI tract infection in patients undergoing dialysis, including the current case. Hematochezia and diarrhea were purported to serve as indicators of CMV GI tract infection among patients on dialysis. Thus, clinicians should suspect CMV infection of the GI tract in dialysis patients, who experience unexplained bloody diarrhea, and promptly perform a GI endoscopy and biopsy.
RESUMO
The hot quadrate sign is defined as an intense arterial enhancement in the hepatic quadrate lobe, most frequently encountered on CT angiograms in patients with central venous occlusion. It has also been described as focal uptake on technetium-99m (Tc99m) sulfur colloid scans. We present an unusual case of focal uptake in the hepatic quadrate lobe on a ventilation-perfusion (V/Q) scan, corresponding to the hot quadrate sign in a 42-year-old patient with chronic kidney disease and central venous occlusion.
RESUMO
Paroxysmal nocturnal hemoglobinuria (PNH) is an uncommon genetic disorder that affects red blood cell production, causing symptoms like fatigue, abdominal pain, and shortness of breath. This condition can also result in dark urine and an increased risk of infections. Diagnosis of PNH involves genetic testing and flow cytometry, which can confirm the presence of the condition. Once a diagnosis is confirmed, personalized treatment plans should be developed to effectively manage the symptoms and improve the patient's quality of life. Treatment options for PNH may include bone marrow transplantation, blood transfusions, and the use of recombinant monoclonal antibody, eculizumab. Regular monitoring is also essential to identify and manage any complications that may arise due to this condition. With proper management and treatment, patients with PNH can lead a healthy and fulfilling life. In this case study, we present a young adult male with PNH who also suffers from renal failure, highlighting the importance of personalized care and ongoing monitoring for this complex condition.
RESUMO
Introduction: Although angiotensin receptor-neprilysin inhibitor (ARNI) has shown promise in patients with heart failure and reduced ejection fraction (HFrEF), the treatment effect in HFrEF patients with end-stage renal disease (ESRD) undergoing dialysis is uncertain. This study aimed to examine the real-world effects of ARNI vs. angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEI/ARB) in this subpopulation. Methods: This multi-institutional, retrospective study identified 349 HFrEF patients with ESRD on dialysis, who initiated either ARNI or ACEI/ARB therapy. Efficacy outcomes included rates of hospitalization for heart failure (HHF) and mortality, as well as changes in echocardiographic parameters. Safety outcomes encompassed hypotension and hyperkalemia. Treatment effects were assessed using Cox proportional hazards models, with additional sensitivity analyses for robustness. Results: Out of 349 patients screened, 89 were included in the final analysis (42 in the ARNI group and 47 in the ACEI/ARB group). After 1 year of treatment, echocardiographic measures between the two groups were comparable. The primary composite rate of HHF or mortality was 20.6 events per 100 patient-years in the ARNI group and 26.1 in the ACEI/ARB group; the adjusted hazard ratio was 0.98 (95% CI: 0.28-3.43, P = 0.97). Their safety outcomes did not differ significantly. Sensitivity analyses, including repetitive sampling, propensity score matching, and extended follow-up, corroborated these findings. Conclusion: ARNI has proven effective in treating HFrEF patients; however, significant benefits were not observed in these patients with ESRD undergoing dialysis compared with ACEI/ARB in this real-world cohort. Future research employing a more extended follow-up period, larger sample size, or randomized design is warranted to investigate the treatment effects in this subpopulation.
RESUMO
Background: Knowledge of one's own chronic kidney disease (CKD) can improve long-term quality of life (QoL). Peritoneal dialysis presents with residual symptoms that reduce the QoL. Objective: To correlate knowledge of the disease and QoL in patients with CKD and on continuous ambulatory peritoneal dialysis (CAPD). Material and methods: A descriptive, cross-sectional, and prospective study was carried out in patients with CKD treated at a second-level hospital of the Mexican Institute for Social Security (Instituto Mexicano del Seguro Social) in Puebla. SF-36 and KiKS questionnaires were applied. Age, sex, education, marital status, perception of QoL, and level of knowledge were recorded. Descriptive statistics and Spearman's coefficient were used. Results: 199 patients with CKD in CAPD were included, 62.8% women, minimum age range was 18 to 20 years with 4% and maximum of 61 years or more with 49.2%, 35.6% of patients completed primary school, and 65.3% were married. The most frequent comorbidity was diabetes (57.2%). The least affected QoL domain was pain. KiKS recorded a mean of 0.54 (regular knowledge about the disease). It was recorded a weak and significant correlation in the QoL domains: physical health, physical role, pain, general health, mental health (p ≤ 0.05). Conclusions: There is a significant but weak correlation between the perception of QoL and the level of knowledge of the disease in CKD patients with CAPD.
Introducción: el conocimiento adecuado de la enfermedad renal crónica (ERC) puede mejorar la calidad de vida (CV) a largo plazo. La diálisis peritoneal cursa con síntomas residuales que reducen la CV. Objetivo: correlacionar el conocimiento de la enfermedad y la CV en pacientes con ERC y en diálisis peritoneal continua ambulatoria (DPCA). Material y métodos: se llevó a cabo un estudio descriptivo, transversal y prospectivo en pacientes con ERC atendidos en un hospital de segundo nivel de atención del Instituto Mexicano del Seguro Social (IMSS) en Puebla. Se les aplicaron los cuestionarios SF-36 y KiKS. Se registró edad, sexo, escolaridad, estado civil, percepción de calidad de vida, nivel de conocimiento. Se utilizó estadística descriptiva y coeficiente de Spearman. Resultados: se incluyeron 199 pacientes con ERC en DPCA, 62.8% mujeres, edad mínima de 18 a 20 años (4%) y máxima 61 años o más (49.2%), 35.6% de los pacientes cursó primaria completa, y 65.3% estaban casados. La comorbilidad más frecuente fue diabetes (57.2%). El dominio de CV menos afectado fue el dolor. El KiKS registró una media de 0.54 (conocimiento regular sobre la enfermedad). Se registró una correlación débil y significativa en los dominios de CV: salud física, rol físico, dolor, salud general, salud mental (p ≤ 0.05). Conclusiones: existe una correlación significativa pero débil entre la percepción de la CV y el nivel de conocimiento de la enfermedad en los pacientes con ERC con DPCA.
