Controversy on the CONVINCE study findings: the PRO take / Controvérsia sobre os achados do estudo CONVINCE: a perspectiva PRO

ABSTRACT The CONVINCE study, recently published in the New England Journal of Medicine, reveals a groundbreaking 23% reduction in the relative risk of all-cause mortality among end-stage kidney patients undergoing high convective volume hemodiafiltration. This significant finding challenges the conventional use of high-flux hemodialysis and offers hope for improving outcomes in chronic kidney disease patients. While some controversies surround the study's findings, including concerns about generalizability and the causes of death, it is essential to acknowledge the study's design and its main outcomes. The CONVINCE study, part of the HORIZON 2020 project, enrolled 1360 patients and demonstrated the superiority of hemodiafiltration in reducing all-cause mortality overall, as well as in specific patient subgroups (elderly, short vintage, non-diabetic, and those without cardiac issues). Interestingly, it was shown that hemodiafiltration had a protective effect against infection, including COVID-19. Future research will address sustainability, dose scaling effects, identification of subgroups especially likely to benefit and cost-effectiveness. However, for now, the findings strongly support a broader adoption of hemodiafiltration in renal replacement therapy, marking a significant advancement in the field.

RESUMO O estudo CONVINCE, publicado recentemente no New England Journal of Medicine, revela uma redução inovadora de 23% no risco relativo de mortalidade por todas as causas entre pacientes renais em estágio terminal submetidos à hemodiafiltração de alto volume de convecção. Esse achado significativo desafia o uso convencional da hemodiálise de alto fluxo e oferece esperança de melhoria dos desfechos em pacientes com doença renal crônica. Embora algumas controvérsias cerquem os achados do estudo, incluindo preocupações sobre a generalização e as causas de óbito, é essencial reconhecer o desenho do estudo e seus principais desfechos. O estudo CONVINCE, parte do projeto HORIZON 2020, inscreveu 1.360 pacientes e demonstrou a superioridade da hemodiafiltração na redução da mortalidade por todas as causas em geral, bem como em subgrupos específicos de pacientes (idosos, HD de curta duração, não diabéticos e aqueles sem problemas cardíacos). Curiosamente, demonstrou-se que a hemodiafiltração teve um efeito protetor contra infecções, incluindo a COVID-19. Pesquisas futuras abordarão sustentabilidade, efeitos de escalonamento da dose, identificação de subgrupos especialmente propensos a se beneficiar e a relação custo-benefício. No entanto, por ora, os achados apoiam fortemente uma adoção mais ampla da hemodiafiltração na terapia renal substitutiva, marcando um avanço significativo na área.

Objective:To investigate the effects of different blood purification methods on their nutritional status and inflammatory response in elderly patients with chronic renal failure.Methods:A total of 120 elderly patients with chronic renal failure who were treated in Lishui People′s Hospital from January 2020 to January 2022 were selected as the research objects, and they were divided into the control group and the observation group according to the random number table method, with 60 cases in each group. The patients in the control group were given hemodialysis alone, and the patients in the observation group were given hemofiltration dialysis treatment on the basis of the patients in the control group. The nutritional status-related indicators, inflammation-related indicators and renal function-related indicators before and after treatment were compared between the two groups.Results:After treatment, the levels of serum total protein (TP), albumin (ALB), hemoglobin (HGB) and creatinine clearance (Ccr) in the observation group were significantly higher than those in the control group: (65.61 ± 4.82) g/L vs. (61.26 ± 3.51) g/L, (36.54 ± 4.52) g/L vs. (31.53 ± 3.32) g/L, (97.58 ± 5.84) g/L vs. (93.06 ± 5.17) g/L, (41.88 ± 4.87) ml/min vs. (34.51 ± 4.36) ml/min, while the levels of interleukin-6 (IL-6), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), creatinine (Cr) and blood urea nitrogen (BUN) were significantly lower than those in control group: (120.09 ± 9.36) ng/L vs. (157.17 ± 14.27) ng/L, (7.15 ± 1.16) mg/L vs. (14.17 ± 2.74) mg/L, (22.14 ± 6.67) ng/L vs. (33.87 ± 7.28) ng/L, (327.16 ± 44.35) μmol/L vs. (378.59 ± 48.27), (10.15 ± 2.03) mmol/L vs. (15.83 ± 3.31) mmol/L, there were statistical differences ( P<0.05). Conclusions:For elderly patients with chronic renal failure, the use of hybrid blood purification can significantly reduce toxins in the body and improve the nutritional status and inflammation of patients, which is worthy of clinical promotion.

Xerostomia impacts oral health-related quality of life in individuals with end-stage renal disease / Xerostomia impacta a qualidade de vida relacionada à saúde bucal de indivíduos em estágio final de doença renal crônica

ABSTRACT Objective: This two-centre cross-sectional study aimed to evaluate whether xerostomia occurrence is associated with oral health-related quality of life (OHRQoL) in patients with end-stage renal disease (ESRD) after the adjustment for potential confounders. Methods: Oral examinations were performed by calibrated examiners for untreated dental caries, periodontitis and tooth loss in 180 adults with ESRD. The presence of xerostomia was determined using the global question "How often does your mouth feel dry?". OHRQoL was evaluated by the simplified version of the Oral Health Impact Profile (OHIP14) questionnaire. Multivariate zero-inflated negative binomial regression analysis was used to calculate the incidence rate ratios (IRR) for the nonzero scores and odds ratios (OR) of having no impact in OHIP14 scores according to the presence of exposure. Results: In the adjusted model, xerostomia (IRR = 1.57; 95% CI: 1.12 to 2.20) was associated with poorer OHRQoL. The adjusted domain-specific analysis revealed that xerostomia occurrence significantly impacted the psychological disability and social disability, and the chance of having no impact was lower for the psychological discomfort domain (OR = 0.84; 95% CI: 0.12 to 0.98). Conclusion: Xerostomia exert an impact on OHRQoL in patients with ESRD, mainly in the psychological and social disabilities constructs.

RESUMO Objetivo: Este estudo transversal realizado em dois centros teve como objetivo avaliar se a ocorrência de xerostomia está associada à qualidade de vida relacionada à saúde bucal (QVRSB) em pacientes com doença renal crônica em estágio final (DRCEF) após o ajuste para potenciais fatores de confusão. Métodos: Exames bucais foram realizados por examinadores calibrados para cárie dentária não tratada, periodontite e perda dentária em 180 adultos com DRCEF. A presença de xerostomia foi determinada por meio da pergunta global "Com que frequência você fica com a boca seca?". A QVRSB foi avaliada pela versão simplificada do questionário Oral Health Impact Profile (OHIP-14). A análise multivariada de regressão binomial negativa inflacionada por zero foi usada para calcular as taxas de incidência (IRR) para os escores diferentes de zero e os razões de chance (OR) de não haver impacto nos escores do OHIP-14 de acordo com a presença dA exposição. Resultados: No modelo ajustado, a xerostomia (IRR = 1,57; IC 95%: 1,12 a 2,20) foi associada a pior QVRSB. A análise específica por domínio revelou que a ocorrência de xerostomia impactou significativamente a incapacidade psicológica e a incapacidade social, e a chance de não haver impacto foi menor para o domínio desconforto psicológico (OR = 0,84; IC95%: 0,12 a 0,98). Conclusão: A xerostomia exerce impacto sobre a QVRSB em pacientes com DRCEF, principalmente nos construtos de deficiência psicológica e social.

Anesthetic and surgical considerations for staged bilateral nephrectomies in a pediatric patient: A case report / Consideraciones anestésicas y quirúrgicas en nefrectomía bilateral en dos tiempos en un paciente pediátrico: Reporte de caso

Abstract We present a 9-year-old patient with end-stage renal disease, on peritoneal dialysis, who underwent a staged prone retroperitoneoscopic bilateral nephrectomy. Bilateral nephrectomy was indicated in preparation for renal transplant in the context of genetic predisposition malignancy when immunosuppressed. The two mirror-image surgeries enable the comparison of the anesthetic management and outcomes in a single patient. Features of interest to anesthesiologists include approach to a child with chronic kidney disease, different requirements for intraoperative antihypertensives; pain management strategies, including a comparison of erector spinae plane block with and without adjunct dexmedetomidine; anesthetic management of retroperitoneoscopic pediatric surgery and the first description of using a Foley bag attached to a peritoneal dialysis catheter to aid in diagnosis and repair of posterior peritoneal cavity entry.

Resumen Se presenta un paciente de 9 años de edad con enfermedad renal terminal, en diálisis peritoneal, quien se sometió a nefrectomía bilateral retroperitoneoscópica estadificada en posición prona. Se indicó la nefrectomía bilateral en preparación para trasplante renal en el contexto de predisposición genética hacia desarrollar una patología maligna al estar inmunosuprimido. Las dos cirugías en espejo permiten hacer una comparación del manejo anestésico y de los desenlaces en un mismo paciente. Las características de interés para los anestesiólogos incluyen el abordaje de un niño con enfermedad renal crónica, con requisitos diferentes de antihipertensivos intraoperatorios; estrategias para el manejo del dolor, incluyendo una comparación de bloqueo del plano del erector espinal con y sin dexmedetomidina adyuvante; manejo anestésico de cirugía pediátrica retroperitoneoscópica y la primera descripción del uso de una bolsa Foley conectada a un catéter de diálisis peritoneal para ayudar en el diagnóstico y la reparación de la entrada de la cavidad peritoneal posterior.

Distúrbio mineral e ósseo: prevalência subestimada nos estágios iniciais da doença renal crônica / Mineral and bone disorder: underestimated prevalence in the early stages of chronic kidney disease / Trastorno mineral y óseo: prevalencia subestimada en las primeras fases de la enfermedad renal crónica

Introdução: o objetivo foi avaliar a prevalência do distúrbio mineral e ósseo em pacientes com doença renal crônica e a associação entre Taxa de Filtração Glomerular estimada (TFGe) e os indicadores do distúrbio mineral e ósseo (DMO) (cálcio, fósforo e PTH) em pacientes renais crônicos não dialíticos. Materiais e Métodos: estudo seccional da linha de base de uma coorte de dois anos, com adultos e idosos renais crônicos em tratamento conservador. Para identificação do DMO utilizamos os seguintes valores séricos: PTH (> 150 pg/mL) e/ou hipocalcemia (Ca < 8,8mg/dl) e/ou hiperfosfatemia (P > 4,6 mg/dl). Na análise estatística utilizou-se: regressão de Poisson; T de Student, Mann Whitney e correlações de Pearson e Spearman. Nível de significância foi de 5%. Resultados: prevalência de DMO de 54,6% (n=41) (IC 95%: 43,45 - 65,43). A maior prevalência de DMO foi em pessoas do sexo feminino, alfabetizadas, idosas, não etilistas, não tabagistas, sedentárias e de cor de pele branca, porém, sem diferença estatística entre os grupos com e sem DMO. As correlações entre P e PTH com TFGe foram significativas, inversas, de força moderada (p= <0,005 e p = 0,003; coeficientes de correlação = - 0,312 e - 0,379 respectivamente). Discussão:os achados desse estudo mostraram que existe uma lacuna no acompanhamento do DMO-DRC pela atenção primária e a prática clínica deve ser revista. Conclusão:identificou-se prevalência robusta de DMO nos estágios precoces da DRC, além de correlações significativas entre o aumento dos níveis de fósforo e PTH e piora das funções renais.

Introduction: mineral and bone disorder (BMD) is a serious complication of chronic kidney disease (CKD) that increases risks for death from cardiovascular causes and impairs quality of life of affected patients. Objetive: to evaluate the prevalence of BMD in patients with CKD and the association between estimated Glomerular Filtration Rate (eGFR) and BMD indicators (calcium, phosphorus and PTH) in non-dialysis patients. Materials and Methods:sectional study of a two-year cohort of chronic renal adults and elderly patients on conservative treatment. BMD was identified by serum values of: PTH (> 150 pg/mL) and/or hypocalcemia (Ca < 8.8mg/dl) and/or hyperphosphatemia (P > 4.6 mg/dl). The statistical analysis used: Poisson regression; Student's T, Mann Whitney and Pearson and Spearman correlations with 5% significance level. Results:BMD prevalence was 54.6% (n=41) (95% CI: 43.45 - 65.43), more frequent in women, literate, elderly, non-drinkers, non-smokers, sedentary and white skin color. Correlations between P and PTH with GFRe were significant, inverse, moderate strength (p= <0.005 and p = 0.003; correlation coefficients = - 0.312 and - 0.379 respectively). Discussion: the findings of this study highlighted gaps in the monitoring of BMD-DRC by primary care, requiring a review of clinical practices. Conclusion: robust prevalence of BMD in the early stages of CKD was identified, in addition to correlations between increased phosphorus and PTH levels and worsening kidney function.

Introducciòn: el trastorno mineral y óseo (TMO) es una complicación grave de la enfermedad renal crónica (ERC) que aumenta el riesgo de muerte por causas cardiovasculares y deteriora la calidad de vida de los pacientes afectados. Objetivo: evaluar la prevalencia de la DMO en pacientes con RDC y la asociación entre la tasa de filtración glomerular estimada (TFGe) y los indicadores de DMO (calcio, fósforo y PTH) en pacientes no dialíticos. Materiales y Métodos: estudio seccional de una cohorte de dos años de pacientes renales crónicos adultos y ancianos en tratamiento conservador. La DMO se identificó por los valores séricos de: PTH (> 150 pg/mL) y/o hipocalcemia (Ca < 8,8mg/dl) y/o hiperfosfatemia (P > 4,6 mg/dl). El análisis estadístico utilizado: regresión de Poisson; T de Student, Mann Whitney y correlaciones de Pearson y Spearman con un nivel de significación del 5%. Resultados: la prevalencia de DMO fue del 54,6% (n=41) (IC 95%: 43,45 - 65,43), más frecuente en mujeres, alfabetizadas, de edad avanzada, no bebedoras, no fumadoras, sedentarias y de color de piel blanca. Las correlaciones entre el P y la PTH con el GFRe fueron significativas, inversas, de fuerza moderada (p= <0,005 y p = 0,003; coeficientes de correlación = - 0,312 y - 0,379 respectivamente). Discusión: los resultados de este estudio evidencian lagunas en el seguimiento de la DMO-DRC por parte de la atención primaria, lo que requiere una revisión de las prácticas clínicas. Conclusión: se identificó una fuerte prevalencia de la DMO en las primeras fases de la ERC, además de correlaciones entre el aumento de los niveles de fósforo y PTH y el empeoramiento de la función renal.

High-flux versus low-flux hemodialysis for end-stage renal disease in the older adults / 中国基层医药

Objective:To investigate the effects of high-flux versus low-flux hemodialysis on end-stage renal disease in older adults and evaluate its effects on myocardial injury indexes and micro-inflammatory response indexes. Methods:Seventy-two patients with ESRD who received treatment in Affiliated Hospital of Shaoxing University from January 2019 to January 2020 were included in this study. They were randomly assigned to receive either low-flux hemodialysis (control group, n = 36) or high-flux hemodialysis (observation group, n = 36). All patients received 6 months of treatment. Micro-inflammatory response indexes and renal function indexes pre- and post-treatment, and reverse reactions were observed in each group. Results:Serum interleukin-6, tumor necrosis factor α, and high-sensitivity C-reactive protein levels post-treatment in the observation group were (7.16 ± 1.32) ng/L, (2.10 ± 0.36) pg/L, (2.20 ± 1.06) mg/L respectively, which were significantly lower than those in the control group [(10.45 ± 1.42) ng/L, (5.22 ± 0.65) pg/L, (3.84 ± 1.57) mg/L, t = 10.19, 25.19, 5.19, all P < 0.001]. Serum parathyroid hormone, B-type natriuretic peptide, and cardiac troponin T levels post-treatment in the observation group were (520.36 ± 95.65) pmol/L, (0.45 ± 0.10) μg/L, (15.05 ± 6.37) ng/L, respectively, which were significantly lower than those in the control group [(830.25 ± 102.35) pmol/L, (0.85 ± 0.13) μg/L, (30.25 ± 6.59) ng/L, t = 13.27, 14.63, 9.95, all P < 0.001]. The total response rate was significantly higher in the observation group than in the control group [75.00% (27/36) vs. 47.22% (19/36), χ2 = 3.85, P < 0.05]. The overall incidence of adverse reactions was significantly lower in the observation group than in the control group [19.44% (7/36) vs. 41.67% (15/36), χ2 = 4.18, P < 0.05). Conclusion:High-flux hemodialysis can highly improve the control effect of micro-inflammatory responses and alleviate myocardial injury in older adult patients with end-stage renal disease. High-flux hemodialysis is more effective and safer than low-flux hemodialysis.

The total adverse reaction rate in the observation group was lower than that in the observation group: 14.29% (7/49) vs. 31.25% (15/48), χ2 = 3.98, P<0.05. Conclusions:CBP therapy for patients with severe heart failure combined with renal failure has better efficacy than IHD, and can improve the patient′s cardiac and kidney function, reduce the levels of p66Shc protein, sFlt-1 and TIMP-1, reduce adverse reactions. It is safe and feasible.

Effect of sacubitril valsartan sodium tablets on serum tenascin-C level and myocardial remodeling in patients of chronic left heart failure complicated with renal failure / 中国医师进修杂志

Objective:To study the effect of sacubitril valsartan sodium tablets on serum tenascin-C (TN-C) level and myocardial remodeling in patients of chronic left heart failure (CHF) complicated with renal failure.Methods:A total of 84 patients with chronic left heart failure complicated with renal failure admitted to Qinhuangdao Jungong Hospital from October 2020 to October 2021 were included and divided into the observation group (treated with sacubitril valsartan sodium tablets) and the control group (treated with valsartan), with 42 cases in each group according to the random number table method. The clinical efficacy of the two groups was compared after 3 months of treatment. The TN-C level and cardiac function index left ventricular end-diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), troponin T (cTnT) and other index before the treatment and after 3 months of treatment were compared between the two groups.Results:After 3 months of treatment, the total effective rate between the two groups had no significant difference ( P>0.05). After 3 months of treatment, the TN-C level in the observation group was lower than that in the control group: (32.42 ± 4.22) μg/L vs. (37.32 ± 4.86) μg/L; and the LVEF in the observation group was higher than that in the control group: (41.21 ± 5.39)% vs. (37.76 ± 5.45)%, the differences were statistically significant ( P<0.05). The LVEDD and cTnT in the two groups had no significant differences ( P>0.05). After 3 months of treatment, neuroendocrine factors norepinephrine, aldosterone, angiotensin Ⅱlevels in the in the observation group were lower than those in the control group: (1 668.60 ± 251.19) pmol/L vs. (2 005.86 ± 280.91) pmol/L, (246.97 ± 13.99) ng/L vs. (275.41 ± 19.38) ng/L, (99.68 ± 8.57) ng/L vs. (112.20 ± 9.52) ng/L, the differences were statistically significant ( P<0.05). Conclusions:Sacubitril valsartan sodium tablets have a good effect in the treatment of CHF complicated with renal failure, which can improve the cardiac function and inhibit the over-activation of neuroendocrine hormones.

Increase in direct costs for health systems due to lupus nephritis: the case of Colombia

ABSTRACT Objective Lupus nephritis is one of the most severe complications of systemic lupus erythematosus and it has been estimated that can occur in up to 60% of patients. Direct costs of lupus nephritis have not been studied in developing countries. This study aimed to describe lupus nephritis direct costs in Colombia. Methods Administrative data from two Colombian health maintenance organizations for 2014 and 2015 was obtained. An algorithm based on the International Statistical Classification of Diseases and Related Health Problems 10th revision codes was developed to identify patients with lupus nephritis and lupus nephritis under study. Results The average annual per-patient, all-claims, all-cause direct cost for lupus nephritis was US$ 12,624, 7.5 times higher than the average lupus patient without lupus nephritis. For lupus nephritis cases under study, estimated direct cost was US$ 3,664, 2 times higher than average lupus patient in Colombia. Difference in lupus nephritis patients is mainly accounted for the cost and frequency of procedures, exceeding by a factor of 5 the cost for durable medical equipment and the cost for drugs, respectively. Conclusion Lupus patients who progress to lupus nephritis stage increased seven-fold the average annual per-patient, all-claims, and all-cause direct cost for the Colombian health system.

Alterações cardíacas em pacientes durante o primeiro ano de hemodiálise crônica: foco em preditores de fibrilação atrial / Cardiac changes in patients during the first year of chronic hemodialysis: focus on predictors of atrial fibrillation

Objetivos: Detecção precoce de alterações cardíacas, em especial de preditores de fibrilação atrial (FA), em pacientes renais crônicos dialíticos, permitem condutas terapêuticas que podem impactar na morbimortalidade cardiovascular desses pacientes. Descrevemos alterações elétricas e estruturais cardíacas nos pacientes durante o 1º ano de hemodiálise (HD). Métodos: Estudo observacional, transversal, prospectivo, em pacientes entre 20 e 80 anos, renais crônicos, pertencentes a serviços públicos de São Paulo, divididos pelo tempo de início de hemodiálise: grupo 1: 1 a 6 meses; grupo 2: 7 a12 meses. Coletados dados sociodemográficos, mórbidos, eletrocardiograma de repouso, Holter 48h, ecocardiograma transtorácico e exames de sangue pré e pós hemodiálise ( função renal, eletrólitos, bicarbonato e inflamatórios). Analisados por teste T student e Qui-quadrado. Resultados: 73 pacientes, hipertensos, predomínio homens, quinquagenários, escolaridade fundamental, brancos, não solteiros, procedentes da região sudeste metropolitana, com multimorbidades e polifarmácia. Grupo 2 apresentou maior idade (p=0,007), morbidades (p=0,04), medicações (p=0,02), preditores de FA caracterizados por extrassístoles ventriculares ( p=0,02), aumento dos volumes e diâmetros ventriculares e átrio esquerdo (todos p≤0,001), alteração do bicarbonato pré e pós hemodiálise (p<0,01). Grupo 1 apresentou maiores alterações eletrolíticas pós hemodiálise (p≤0,03). Conclusão: Além da hipertensão arterial, tempo de hemodiálise, acidose metabólica próxima dos limites de referência, associaram-se precocemente à progressiva disfunção sisto-diastólica de câmaras esquerdas cardíacas e preditores de fibrilação atrial, em especial o volume sistólico final, predominantemente no 2º semestre do início de hemodiálise. Sugere-se Holter e Ecocardiograma a partir do 7º mês de hemodiálise e controles mais rígidos de acidose para essa população.

Objectives: Early detection of cardiac alterations in chronic renal patients on hemodyalisis (HD), especially atrial fibrillation (AF) predictors, allows therapeutic approaches that can impact their cardiovascular prognosis. We describe electrical and structural cardiac alterations in patients during the 1st year of hemodyalisis. Methods: Observational, cross-sectional, prospective study. Chronic kidney patients on dyalisis aged between 20 and 80 years, wihout atrial fibrillation, from public hemodyalisis services were divided by the time of hemodyalisis onset: group 1: 1 to 6 months; group 2: 7 to 12 months. Sociodemographic and morbid data, electrocardiogram at rest, Holter 48h, transthoracic echocardiogram and pre and post hemodialysis blood tests (kidney function, electrolytes and inflammatory tests) were collected. Data analyzed by Chi-square and Student T tests. Results: 73 hypertensive patients, predominantly men, aged in their fifties, elementary school, white, not single, from the metropolitan southeast region, with multimorbidities and polypharmacy were analyzed. Group 2 presented more age (p<0.01), morbidities (p=0.04), medications (p=0.02), atrial fibrillation, predictors especially ventricular extrasystoles (VES, p=0.02), increased left venticular and atrium volumes and diameters (all p≤0.001) and lower bicarbonate before and after hemodyalisis (both p≤0,01). Group 1 presented more changes in eletrolytes (p≤0.03). Conclusion: In addition to arterial hypertension, hemodyalisis duration was associated to systolic and diastolic dysfunction of the left cardiac chambers, atrial fibrillation predictors especially end-systolic volume (ESV) and mild acidosis, in the 2nd semestre predominantly. Holter and echocardiography are suggested from the 7th month of hemodyalisis onset and tighter metabolic control in this population

Coordenação de cuidados primários para o paciente com doença renal crônica em diálise: revisitando papéis / Coordination of primary care for patients with chronic kidney disease on dialysis: revisiting roles

O número de pessoas em diálise tem aumentado de maneira significativa nos últimos anos. Essas pessoas são, em geral, portadoras de condições crônicas múltiplas e complexas, e a coordenação do seu cuidado torna-se um desafio. O presente artigo objetiva sintetizar os resultados da literatura a respeito da coordenação do cuidado e dos cuidados primários ofertados ao paciente em diálise. Trata-se de uma revisão integrativa que teve como fontes de dados publicações disponíveis nas bases: LILACS, SciELO e PubMed. Foram identificados 16 artigos publicados entre 1992 e 2020. A partir da análise temática, evidenciaram-se cinco áreas: vínculo das pessoas em diálise com a Atenção Primária à Saúde (APS) e com o médico da família e comunidade (MFC); percepção dos profissionais quanto a seus papéis e habilidades; percepção das pessoas a respeito dos papéis e habilidades dos profissionais; cuidados primários (CP) prestados por nefrologistas e MFC; e impacto da APS na mortalidade, hospitalização e qualidade de vida. Os resultados sugerem que o nefrologista tem assumido o papel de coordenador do cuidado e de principal provedor de CP à pessoa em diálise. Todavia, isso não significa queos cuidados oferecidos sejam adequados às necessidades do paciente, devendo o MFC estar cada vez mais envolvido com esse cuidado, o que tem sido gradualmente observado nos últimos anos.

The number of patients on dialysis has increased significantly in recent years. These patients are, in general, carriers of multiple and complex chronic conditions, and the coordination of their care becomes a challenge. This article aims to summarize the results of the literature regarding the coordination of care for dialysis patients. This is an integrative review based on data published and available in the databases: LILACS, SciELO, and PubMed. 16 articles published between 1992 and 2020 were identified. Based on the thematic analysis, five areas were highlighted: linkage of patients with primary health care (PHC) and with the family and community physician (FCF); professionals' perception of their roles and skills; patients' perception of the professionals' roles and skills; primary care delivered by nephrologists and FCF; and the impact of PHC on mortality, hospitalization, and quality of life. The results suggest that nephrologists have assumed the role of care coordinators and main providers of primary care for dialysis patients. However, this does not mean that the care offered is adequate for the patient's needs, and the FCF should be increasingly involved with this care, which indeed began to gradually occur in recent years.

Brazilian dialysis survey 2019 / Inquérito brasileiro de diálise 2019

Abstract Introduction: National data on chronic dialysis treatment are essential for the development of health policies that aim to improve the treatment of patients. Objective: To present data from the Brazilian Dialysis Survey 2019, promoted by the Brazilian Society of Nephrology. Methods: Data collection from dialysis units in the country through a completed online questionnaire for 2019. Results: 314 (39%) centers responded the questionnaire. In July 2019, the estimated total number of patients on dialysis was 139,691. Estimates of the prevalence and incidence rates of patients undergoing dialysis treatment per million of the population (pmp) were 665 and 218, respectively, with mean annual increases of 25 pmp and 14 pmp for prevalence and incidence, respectively. The annual gross mortality rate was 18.2%. Of the prevalent patients, 93.2% were on hemodialysis and 6.8% on peritoneal dialysis; and 33,015 (23.6%) on the waiting list for transplantation. 55% of THE centers offered treatment with peritoneal dialysis. Venous catheters were used as access in 24.8% of THE patients on hemodialysis. 17% of the patients had K ≥ 6.0mEq/L; 2.5% required red blood cell transfusion in July 2019 and 10.8% of the patients had serum levels of 25-OH vitamin D < 20 ng/mL. Conclusion: The absolute number of patients, the incidence and prevalence rates in dialysis in the country continue to increase, as well as the percentage of patients using venous catheter as dialysis access. There was an increase in the number of patients on the list for transplantation and a tendency to reduce gross mortality.

La microalbuminuria en el diagnóstico precoz del daño renal en pacientes diabéticos / Microalbuminuria in the Early Diagnosis of Kidney Damage in Diabetic Patients

RESUMEN Fundamento: la detección precoz de microalbuminuria en el paciente diabético es considerada como el mejor y más temprano marcador de nefropatía diabética. En la actualidad se le considera como un marcador de disfunción endotelial y enfermedad vascular. Objetivo determinar el comportamiento de la microalbuminuria en pacientes diabéticos pertenecientes al consultorio médico número 25 del Policlínico Comunitario Docente Presidente Salvador Allende de La Habana. Métodos: se realizó un estudio descriptivo de corte transversal. El universo lo constituyeron 1125 personas pertenecientes al consultorio médico. La muestra estuvo constituida por los 62 pacientes con diabetes mellitus. El estudio se realizó en el período de enero a diciembre del 2018. El diagnóstico de microalbuminuria se realizó después de comprobada en dos determinaciones de las tres realizadas en un período de 6 meses, quedando constituido dos grupos de pacientes según se determinó la presencia o no de microalbuminuria. Resultados: el 11,3 % de los pacientes diabéticos presentaron microalbuminuria. La presencia de microalbuminuria fue mayor en el sexo masculino (12,9 %), en los mayores o iguales a 70 años (21,4 %), en los diabéticos con tiempo de evolución de la enfermedad de 20 o más años (18,7 %), en los pacientes con diabetes mellitus insulino-dependiente (50 %) y en los pacientes con descontrol grave de la enfermedad (55,6 %). Conclusiones: la microalbuminuria predomina en los pacientes diabéticos de mayor edad, está relacionada con el tiempo de evolución de la diabetes mellitus. La microalbuminuria tiene relación con el control metabólico. Es más frecuente en los pacientes con diabetes mellitus insulino-dependiente.

ABSTRACT Background the early detection of microalbuminuria in diabetic patients is considered the best and earliest marker of diabetic nephropathy. It is currently considered as a marker of endothelial dysfunction and vascular disease. Objective to determine the behavior of microalbuminuria in diabetic patients belonging to the medical office 25 of the Presidente Salvador Allende Teaching Community Polyclinic in Havana. Methods a descriptive cross-sectional study was carried out. The universe was made up of 1125 people belonging to the medical office. The sample consisted of 62 patients with diabetes mellitus. The study was carried out from January to December 2018. The diagnosis of microalbuminuria was made after it was verified in two determinations of the three carried out in a period of 6 months, with two groups of patients being constituted according to whether the microalbuminuria presence or not was determined. Results the 11.3 % of the diabetic patients presented microalbuminuria. The presence of microalbuminuria was higher in males (12.9 %), in those older than or equal to 70 years old (21.4 %), in diabetics with a disease evolution time of 20 or more years (18, 7 %), in patients with insulin-dependent diabetes mellitus (50 %) and in patients with severe lack of control of the disease (55.6 %). Conclusions microalbuminuria predominates in older diabetic patients it is related to the diabetes mellitus evolution time. It is related to metabolic control. It is more common in patients with insulin-dependent diabetes mellitus.

Urgent vs. early-start peritoneal dialysis: patients' profile and outcomes / Diálise peritoneal de urgência vs. início precoce: perfil dos pacientes e resultados

ABSTRACT Introduction: Peritoneal dialysis (PD) has been considered a safe option of therapy in end-stage renal disease patients with urgent need of dialysis. Recently, it was proposed that Urgent-Start-PD (US-PD) be defined when PD starts within 72 hours after catheter placement and "early start" PD (ES-PD) when PD starts between 3 and 14 days after. We aimed to compare demographic and clinical characteristics between patients in US-PD and ES-PD as well as 30-day complications, 6-month hospitalization, and dropout rate. Methods: Adult patients starting PD within 14 days after catheter insertion (October/2016 - February/2019) were included and divided into US-PD group and ES-PD group based on the their PD initiation time. Clinical and demographic data, fill volume for the first PD session, 30-day complications, 6-month hospitalization, and dropout rate were assessed. Results: In our study, 72 patients were analyzed (US-PD=40, ES-PD=32) with mean age of 53.2±15.2 years old. No differences between US-PD and ES-PD regarding demographic characteristics, 30-day complications, 6-month hospitalization, and dropout events were found. The most frequent short-term complication in patients who started PD urgently was leakage. The most common cause of dropout was transfer to HD. Conclusion: Fifty five percent of our sample started PD less than 72 hours after catheter insertion. The lack of difference in the measured outcomes compared to patients that had therapy initiated after this period encourages the use of urgent PD when needed.

RESUMO Introdução: A diálise peritoneal (DP) tem sido considerada uma opção segura de terapia em pacientes com doença renal terminal com necessidade urgente de diálise. Recentemente, foi proposto que a DP de início urgente (US-PD) fosse definida quando a DP iniciar dentro de 72 horas após o implante do cateter, e a DP de "início precoce" (ES-PD) quando a DP iniciar entre 3 e 14 dias após o procedimento. Nosso objetivo foi comparar características demográficas e clínicas entre pacientes em US-PD e ES-PD, bem como complicações em 30 dias, internação por 6 meses e taxa de saída do tratamento. Métodos: Pacientes adultos iniciando DP em até 14 dias após a inserção do cateter (outubro/2016 - fevereiro/2019) foram incluídos e divididos no grupo US-PD ou ES-PD com base no tempo de início da DP. Dados clínicos e demográficos, volume de preenchimento na primeira sessão de DP, complicações em 30 dias, hospitalização por 6 meses e taxa de saída foram avaliados. Resultados: Em nosso estudo, 72 pacientes foram analisados (US-PD = 40, ES-PD = 32) com média de idade de 53,2 ± 15,2 anos. Não foram encontradas diferenças entre US-PD e ES-PD em relação às características demográficas, complicações em 30 dias, hospitalização por 6 meses e saída do tratamento. A complicação de curto prazo mais frequente nos pacientes que iniciaram a DP com urgência foi o extravasamento de líquido peritoneal. A causa mais comum de saída foi a transferência para HD. Conclusão: Mais da metade da nossa amostra iniciou a DP menos de 72 horas após a inserção do cateter. A falta de diferença nos desfechos mensurados em comparação com os pacientes que iniciaram o tratamento após esse período incentiva o uso de US-PD quando necessário.

Salivary and Serum Biochemical Analysis from Patients with Chronic Renal Failure in Hemodialysis: A Cross-Sectional Study

ABSTRACT Objective: To compare salivary and serum biochemical levels in patients with chronic renal failure undergoing hemodialysis. Material and Methods: The sample was composed of 57 patients treated in Hemodialysis Reference Centers, from a state of Northeastern Brazilian, with age ≥21 years old with at least 3 months of hemodialysis treatment time. Serum data were obtained from records. Unstimulated and stimulated saliva were collected. Flow rate (mL/min) was measured. Spectrophotometry was performed for the measurement of salivary levels of calcium (570 nm), urea (340 nm), and creatinine (510 nm). Statistical analysis used Mann Whitney and Kruskal-Wallis tests (p<0.05). Results: Unstimulated and stimulated salivary flow rates were 0.43 mL/min and 1.69 mL/min, respectively. There was significant difference (p<0.001) of levels of calcium (5.41 mg/dL and 9.70 mg/dL), urea (118.03 mg/dL and 183.22 mg/dL) and creatinine (0.59 mg/dL and 9.20 mg/dL) between saliva and serum, respectively. Concerning the time of hemodialysis, salivary and serum calcium not exhibited significant association; however, serum urea (p=0.012) and serum creatinine (p=0.025) showed significant association to the time of hemodialysis. Conclusion: Salivary biochemical levels of urea, creatinine and calcium can indicate the presence of a possible chronic renal failure and the saliva demonstrated to be a potential auxiliary biofluid for clinical monitoring renal alterations.
