Enfermedad oncoproliferativa en el receptor de trasplante renal. Nuestra experiencia / Oncoproliferative diseases in kidney transplant recipients. Our experience

Introducción: El cáncer conlleva a una mortalidad de hasta 12 % en los pacientes trasplantados, y se considera la tercera causa de morbilidad y mortalidad en los receptores, al ser estos susceptibles a desarrollar enfermedades oncoproliferativas, a largo plazo. Objetivo: Describir la incidencia de neoplasias en receptores de trasplante renal. Métodos: Estudio descriptivo y longitudinal que incluyó 15 receptores de trasplante renal funcionante, con diagnóstico de neoplasias malignas en diferentes localizaciones en el período comprendido entre enero de 2017 y junio de 2023 en el servicio de Nefrología del Hospital Universitario Clínico-Quirúrgico «Arnaldo Milián Castro» de Santa Clara, Villa Clara. Resultados: Predominaron los hombres y el color de piel blanca: 53,3 % y 73,3% respectivamente, con tiempo postrasplante superior a tres años en 12 pacientes (80 %). El antecedente de exposición al citomegalovirus representó el 80 %; la infección bacteriana de la vía respiratoria y digestiva fue la más frecuente. Conclusiones: La neoplasia intraepitelial cervicouterina, la de colon con metástasis hepática y las cerebrales resultaron las más frecuentes, y fueron tratadas con cirugía, quimioterapias o ambas, según los criterios quirúrgicos en cada caso; no obstante, la mortalidad fue elevada. La estirpe neoplásica preponderante fue la neoplasia intraepitelial cervical en un 26,6 %. La mortalidad fue alta y la supervivencia fue menor en el sexo masculino, sin rebasar los dos años posteriores al diagnóstico.

Introduction: cancer entails a mortality of up to 12 % in transplanted patients and is considered the third leading cause of morbidity and mortality in recipients who are susceptible to develop oncoproliferative diseases in the long term. Objective: to describe the incidence of neoplasms in renal transplant recipients. Methods: we carried out a descriptive and longitudinal study including 15 functioning renal transplant recipients who were diagnosed with malignant neoplasms in different locations in the Nephrology service at "Arnaldo Milián Castro" Clinical and Surgical University Hospital in Santa Clara, Villa Clara between January 2017 and June 2023. Results: males and white skin color predominated: 53.3 % and 73.3% respectively, with post-transplant time greater than three years in 12 patients (80 %). The history of cytomegalovirus exposure represented 80 %; bacterial infection of the respiratory and digestive tracts was the most frequent. Conclusions: cervicouterine intraepithelial neoplasia, colon cancer with liver and brain metastases were the most frequent and treated with surgery chemotherapies or both according to the surgical criteria in each case; however, mortality was elevated. Cervical intraepithelial neoplasia predominated in a 26.6 %. Mortality was high and survival was lower in males, without exceeding two years after the diagnosis.

Hypertension maligne à l'hôpital Fousseyni Daou de Kayes, au Mali: aspects épidémio-cliniques et pronostiques / Malignant hypertension at the Fousseyni Daou hospital in Kayes, Mali: epidemiological and prognostic aspects

L'hypertension artérielle maligne (HTAM) est un problème de santé publique en Afrique subsaharienne. L'objectif de cette étude était de décrire le profil épidémio-clinique et les facteurs pronostiques de l'HTAM à Fousseyni DAOU de Kayes. Méthodes. Nous avons réalisé une étude rétrospective et descriptive du 1er janvier 2016 au 31 juin 2022 à l'unité de néphrologie de l'hôpital Fousseyni Daou de Kayes. Étaient inclus, les patients hypertendus ou normotendus sous traitement hospitalisés avec une rétinopathie hypertensive (RH) de stade II ou III (selon la classification de Kirkendall) associée à une ou plusieurs autres atteintes viscérales et ayant un dossier médical complet. Résultats. Au total 117 cas d'HTAM ont été enregistrés sur 7011 dossiers examinés, dont 53,8% d'hommes (63 cas). L'âge moyen était de 39,47 ans. La moyenne de la pression artérielle à l'admission était de 187/114 mmHg. La RH était de stade II et III dans 59,8% et 40,2% des cas. L'insuffisance rénale était retrouvée chez 93,1% des patients (109 cas) dont 63,7% d'insuffisance rénale chronique (IRC) contre 36,7% d'insuffisance rénale aiguë (IRA). L'hypertrophie ventriculaire gauche a été retrouvée dans 80,4% des cas. L'issue globale des patients a été favorable dans 59% (69 cas) contre 31,6% (37 cas) de décès et 9,4% (11 cas) de sortie contre avis médical. Les facteurs associés au risque de décès étaient surtout la RH stade III, la dyslipidémie, l'IRC terminale et l'hyponatrémie. Conclusion. L'HTAM reste un problème de santé publique au Mali et touche préférentiellement les sujets jeunes avec une morbi mortalité élevée

Facteurs associés à l'hospitalisation prolongée et à la mortalité au niveau du service de néphrologie de l'hôpital Aristide Le Dantec de Dakar / Factors associated with prolonged hospitalization and mortality in the nephrology department of the Aristide Le Dantec hospital in Dakar

Introduction : L'hospitalisation en néphrologie n'avait pas fait l'objet de plusieurs études au Sénégal et les données sont limitées. Notre travail avait pour but de déterminer les facteurs associés à l'hospitalisation prolongée et à la mortalité en néphrologie. Patients et méthodes : Il s'agissait d'une étude observationnelle prospective de 5 mois incluant tous les patients hospitalisés dans le service durant au moins 24H. La durée d'hospitalisation (la période allant du jour d'admission dans la chambre d'hospitalisation au jour de sortie du patient) était dite prolongée si > 12 jours. Résultats : Quatre-vingt-dix-neuf patients ont été analysés durant cette période avec une durée moyenne en hospitalisation de 11,14 ± 9,89 jours. L'âge moyen était de 45,22 ± 18,03 ans avec un sex-ratio (H/F) de 0,62. Les anomalies biologiques étaient : l'hyponatrémie (62,36%), l'hypokaliémie (23,91%), l'hypocalcémie (25%), l'hyperphosphatémie (51,21%), l'anémie (92,30%), la CRP élevée (90,90%) et l'hypoalbuminémie (80,76%). La protéinurie moyenne était de 3,38 ± 3,35 g/24h avec 34,61% de protéinurie néphrotique. La mortalité hospitalière était de 25,25%. En analyse univariée, l'hospitalisation prolongée était associée à l'âge ≤ 45 ans (p = 0,018), aux patients non dialysés chroniques (p=0,034), à la transfusion sanguine (p=0,008) tandis que la mortalité était liée à l'âge de plus de 45 ans (p=0,032), le diabète (p=0,014), l'hypokaliémie (p=0,045) et l'hospitalisation prolongé (p=0,007). En analyse multivariée, les patients présentant des œdèmes et ceux ayant été transfusés avaient respectivement 2,89 et 3,9 fois plus de risque d'avoir une hospitalisation prolongée. Les patients diabétiques avaient 4,63 fois plus de risque de décès et ceux ayant été hospitalisés de plus de 12 jours avaient 0,14 fois de risque de décès. Conclusion : La durée d'hospitalisation était relativement prolongée avec une mortalité élevée. Cependant l'impact de certains facteurs a été démontré permettant ainsi de réduire la durée d'hospitalisation et le nombre de décès.

Introduction: Hospitalization in nephrology had not been the subject of several studies in Senegal and the data are limited. Our work aimed to determine the factors associated with prolonged hospitalization and mortality in nephrology. Patients and methods: This was a 5-month prospective observational study including all patients hospitalized in the department for at least 24 hours. The duration of hospitalization (the period from the day of admission to the hospital room to the day of the patient's discharge) was said to be prolonged if > 12 days. Results: Ninety-nine patients were analyzed during this period with an average hospital stay of 11.14 ± 9.89 days. The mean age was 45.22 ± 18.03 years with a sex ratio (M/F) of 0.62. The biological abnormalities were: hyponatremia (62.36%), hypokalemia (23.91%), hypocalcemia (25%), hyperphosphatemia (51.21%), anemia (92.30 %), elevated CRP (90.90%) and hypoalbuminemia (80.76%). The mean proteinuria was 3.38 ± 3.35 g/24h with 34.61% nephrotic proteinuria. Hospital mortality was 25.25%. In univariate analysis, prolonged hospitalization was associated with age ≤ 45 years (p = 0.018), chronic non-dialysis patients (p = 0.034), blood transfusion (p = 0.008) while mortality was related to age over 45 (p=0.032), diabetes (p=0.014), hypokalaemia (p=0.045) and prolonged hospitalization (p=0.007). In multivariate analysis, patients with edema and those who had been transfused were respectively 2.89 and 3.9 times more likely to have prolonged hospitalization. Diabetic patients had a 4.63 times greater risk of death and those who had been hospitalized for more than 12 days had a 0.14 times greater risk of death. Conclusion: The duration of hospitalization was relatively prolonged with high mortality. However, the impact of certain factors has been demonstrated, thus making it possible to reduce the duration of hospitalization and the number of deaths

Chronic kidney disease represents a serious public health problem, due to the increasing rates of morbidity and mortality, which, associated with the routine of hemodialysis sessions, promotes changes in the quality of life of individuals with this condition. Objective: To evaluate factors related to the quality of life of chronic renal patients undergoing hemodialysis. Design and location: Cross-sectional, quantitative study, composed of 52 hemodialysis patients at the Santa Casa de Caridade hospital in Diamantina, Diamantina (MG), in 2017. Methods: Two questionnaires were used: socioeconomic-demographic and the Kidney Disease and Quality of instrument life Short Form. Data on quality of life were analyzed using the program developed and made available by the Working Group. Results: As factors related to low quality of life were found: occupational situation (33.65 ± 26.71), weight of kidney disease (49.28 ± 21.58), physical functioning (53.37 ± 22.39), general health (54.71 ± 27.19) and emotional function (58.97 ± 26.23); in relation to good quality of life, sexual function (80.17 ± 22.46), cognitive function (80.26 ± 35.32), patient satisfaction (83.33 ± 20.51) and stimulation on the part were found of the dialysis team (91.59 ± 29.17). Discussion: Comparing the studies carried out in Goiânia (2006), Indaiatuba (2009), Mogi das Cruzes (2014) and the present study (2017) found similar scores in most of the dimensions evaluated, such as social functions and patient satisfaction. Conclusion: Quality of life was shown to be good in most of the dimensions evaluated, however, the determinants of low quality of life reinforce the idea of implementing health team strategies to improve the life expectancy of these patients.

The first appointment with a nephrologist: Brazilian patients' demographic and kidney function characteristics. A retrospective study

ABSTRACT BACKGROUND: The number of nephrologists has risen slowly, compared with the prevalence of chronic kidney disease (CKD) in Brazil. Data on patients referred to nephrology outpatient clinics remains scarce. OBJECTIVE: To determine the demographic and kidney function characteristics of patients at their first appointment with a nephrologist. DESIGN AND SETTING: Retrospective study conducted at three nephrology outpatient clinics (public and private services), in São Paulo, Brazil. METHODS: From December 2019 to February 2020, we collected patient data regarding demographics, kidney function parameters and comorbidities. We then analyzed data on 394 patients who met a nephrologist for their first appointment. RESULTS: The main comorbidities were hypertension (63.7%), diabetes (33.5%) and nephrolithiasis (22.3%). Regarding CKD stages, 24.1%, 9.1%, 13.7%, 15.2%, 15.2% and 2.3% of the patients were in stages 1, 2, 3a, 3b, 4 and 5, respectively. Proteinuria was absent or mild, moderate and high in 17.3%, 15.2% and 11.7%, respectively; and 16.2% had not undergone previous investigation of serum creatinine or proteinuria (55.8%). For 17.5%, referral to a nephrologist occurred late. Patients in public services were older than those in private services (59 years versus 51 years, respectively; P = 0.001), more frequently hypertensive (69.7% versus 57.5%; P = 0.01) and reached a nephrologist later (22.4% versus 12.4%; P = 0.009). CONCLUSION: Referrals to a nephrologist were not being made using any guidelines for CKD risk and many cases could have been managed within primary care. Late referral to a nephrologist happened in one-fifth of the cases and more frequently in the public service.

Resumen El filtrado glomerular (FG) se considera el mejor índice para evaluar la función renal en la práctica clínica. Recientemente, ha ganado popularidad la utilización de ecuaciones que estiman el FG, en distintas poblaciones, a partir de los niveles séricos de algunos biomarcadores. Sin embargo, no todas las fórmulas han sido validadas en los diversos escenarios clínicos probables. Las sociedades participantes: Sociedad Argentina de Nefrología, Asociación Bioquímica Argentina, Fundación Bioquímica Argentina y Confederación Unificada Bioquímica de la República Argentina, integradas por nefrólogos y bioquímicos, realizaron un consenso actualizado sobre la utilización del FG como herramienta de detección de la enfermedad renal crónica (ERC) en la Argentina. Se analizó la bibliografía existente y, teniendo en cuenta aspectos de nuestra realidad sanitaria, se establecieron sugerencias para su utilización. Se actualizaron las indicaciones del uso del FG medido. En sucesivos capítulos se puso foco en distintos estados del FG en diversas poblaciones y situaciones. En los estados de reducción del FG, se mencionaron tanto los fisiológicos propios del envejecimiento, como los determinados por situaciones patológicas, por ejemplo, el observado en la ERC avanzada o el determinado en aquellos pacientes que recibieron un trasplante renal. Se revisaron, por otro lado, las situaciones de incremento del FG, como las observadas en el embarazo o en la obesidad. Se refirieron, asimismo, las limitaciones de la estimación del FG, se reconoció su valor en situaciones de la práctica clínica habitual, o en contextos epidemiológicos definidos y se sugirieron las ecuaciones más adecuadas para su utilización en cada caso.

Abstract The glomerular filtration rate (GFR) is considered the best index to assess the renal function in clinical practice. Recently, the use of equations to estimate GFR in different populations, based on the serum levels of some biomarkers, has gained popularity. However, not all the equations have been validated in the various likely clinical scenarios. Thus, the participating societies, i.e. the Argentine Society of Nephrology, the Argentine Association of Biochemistry, the Argentine Foundation of Biochemistry, and the Unified Confederation of Biochemistry of Argentina, composed of nephrologists and biochemists, have established an updated consensus on the use of the GFR as a tool for the detection of chronic kidney disease (CKD) in Argentina. The consensus was established on the basis of the analysis of the existing literature and taking into account aspects of the health situation in Argentina. Suggestions for the use of the GFR were made, and the indications for its use were updated. The successive chapters of the consensus consider different values of the GFR in different populations and situations. The different situations considered and reviewed include cases of a decrease in the GFR, such as the physiological one related to aging and that related to pathological situations, as observed in advanced CKD or in patients who have received a kidney transplant, as well as cases of an increase in the GRF, such as that observed in pregnancy or obesity. The consensus also mentions the advantages and limitations of the estimation of the GFR in situations of usual clinical practice or in specific epidemiological contexts, and the most appropriate equations for its use in each case is suggested.

Foram referidas, também, as limitações da estimativa da FG, foi reconhecido o seu valor em situações da prática clínica habitual, ou em contextos epidemiológicos definidos e se sugeriram equações mais adequadas para sua utilização em cada caso.

Etiologies des pneumopathies bactériennes non tuberculeuses en milieu néphrologique au centre Hospitalo-Universitaire du Point G à Bamako, Mali / Etiologies of non-tuberculous bacterial pneumonitis in a nephrological environment at Point G University Hospital in Bamako, Mali

Contexte + objectif : les signes cliniques et paracliniques en particulier radiologique ne sont pas spécifi ques d'un processus infectieux. L'objectif de cette étude était de déterminer les micro-organismes non tuberculeux en cause au cours des infections respiratoires dans le service de Néphrologie du CHU du Point G. Méthode : il s'agissait d'une étude prospective et descriptive allant du 1er janvier 2018 au 30 juin 2019, soit 18 mois. Etaient inclus, tous les patients en insuffi sance rénale chronique (IRC) souffrant d'une pneumopathie infectieuse diagnostiquée cliniquement, radiologiquement et/ou bactériologiquement. Résultats : Nous avons colligés 35 patients, 21 hommes et 14 femmes. L'âge moyen a été de 46,8 ± 13,9 ans avec des extrêmes de 23 et 76 ans. Les patients âgés de plus de 45 ans étaient majoritaires (54,3%). L'IRC était terminale chez tous nos patients avec un débit de fi ltration glomérulaire moyen de 6,7 ml/min/1,73m2. La radiographie thoracique de face a révélé une pneumopathie alvéolaire (65,7%), une pleuropneumopathie (28,6%) et une pneumopathie cavitaire (5,7%). Les bactéries non tuberculeuses retrouvées à l'examen cytobactériologique des crachats étaient : Klebsiella pneumoniae (25,7%), Escherichia coli (11,4%), Citrobacter frendii, Pseudomonas aeroginosa, Staphylococcus aureus, Candida albicans soit 5,7% pour chacune, Enterobacter clocae et Enterococcus sp avec 2,9% chacune. Quatre (11,4%) sur 35 présentaient une tuberculose dont 1 cas (2,9%) de coïnfection de germe banal. Conclusion: Le diagnostic de la tuberculose par bacilloscopie entraine des cas de méconnaissance des germes banals associés.

Context and objective. Clinical and paraclinical signs, in particular radiological signs, are not specifi c to an infectious process. The objective of this study was to determine the non-tuberculous microorganisms involved in respiratory infections in the Nephrology department of the CHU du Point G. Methods. This was a prospective and descriptive study from January 1, 2018 to June 30, 2019, (18 months). Included were all patients with chronic renal failure (CKD) suffering from an infectious pneumonia diagnosed clinically, radiologically and / or bacteriologically. Results. We collected 35 patients, 21 men and 14 women. The mean age was 46.8 ± 13.9 years with extremes of 23 and 76 years. The majority of patients over the age of 45 were 54.3%. IRC was terminal in all of our patients with an average glomerular filtration rate of 6.7 ml / min / 1.73m2. The chest chest X-ray revealed alveolar pneumonitis (65.7%), pleuropneumopathy (28.6%) and cavitary pneumonitis (5.7%). The non-tuberculous bacteria found on cytobacteriological examination of sputum were: Klebsiella pneumoniae (25.7%), Escherichia coli (11.4%), Citrobacter frendii, Pseudomonas aeroginosa, Staphylococcus aureus, Candida albicans, or 5.7% for each , Enterobacter clocae and Enterococcus sp with 2.9% each. Four (11.4%) out of 35 presented with tuberculosis, including 1 case (2.9%) of common coinfection. Conclusion. The diagnosis of tuberculosis by bacilloscopy leads to cases of ignorance of the associated banal germs.

Progression of chronic kidney disease in non- dialysis patients: a retrospective cohort

Abstract Evidence on factors associated with the progression of chronic kidney disease (CKD) is still under construction. The present study aimed to evaluate sociodemographic, clinical, and drug use factors associated with the progression of CKD. A retrospective cohort study was conducted with 193 patients with CKD stages 3A to 5- non-dialysis followed for three years in a Brazilian city. The outcome was the evolution to renal replacement therapy (RRT) or death. A total of 52.3 % (n = 101) were men and 83.4 % (n = 161) elderly. The median age was 72.0 years, and 22.3 % (n = 44) progressed to RRT or death, and the three-year mortality rate was 20.2 %. Participants exposed to angiotensin converting enzyme inhibitors or angiotensin II receptor blockers had a lower risk of progressing to the outcome (hazard ratio (HR) 0.25; p = 0.003) and higher survival (p = 0.022) when compared to those not exposed to these drugs. Age (HR 1.06;) and use of omeprazole (HR 6.25; CI; p <0.01) and hydrochlorothiazide (HR 2.80; p = 0.028) increased the risks of RRT or death. The results highlight the importance of rational management of pharmacotherapy for patients with CKD

Calidad del sueño en pacientes con enfermedad renal crónica / Sleep quality in patients with chronic kidney disease

Introducción: los pacientes con enfermedad renal crónica (ERC), y en específico los que tienen tratamiento renal sustitutivo (TRS), se ven afectados en su ciclo circadiano y en su calidad del sueño. Objetivo: evaluar la calidad del sueño de los pacientes con enfermedad renal crónica que acuden al servicio de Nefrología de una unidad médica de segundo nivel de atención. Metodología: estudio comparativo en pacientes con ERC del servicio de Nefrología, clasificados en tres grupos, dos de ellos en terapia de reemplazo renal (diálisis peritoneal y hemodiálisis) y uno sin terapia de reemplazo renal (prediálisis). Para la calidad del sueño se utilizó la escala de Pittsburgh, se incluyeron datos sociodemográficos y parámetros bioquímicos. Los datos se analizaron median- te comparación de frecuencias con Chi cuadrada, medias con t de Student y ANOVA de un factor. Resultados: se formaron tres grupos: hemodiálisis (n = 75), diálisis peritoneal (n = 58) y prediálisis (n = 71). La edad media fue de 53.5 años; la calidad subjetiva del sueño fue buena en el 48% del total y en el 54.9% de los pacientes en prediálisis (p < 0.05). Al aplicar la escala de Pittsburgh, el 80.4% del total y el 84.5% de los pacientes en diálisis reportaron una calidad de sueño mala. De las siete dimensiones evaluadas, dos fueron diferentes en los tres grupos (p < 0.05). Conclusiones: la percepción del paciente sobre la calidad del sueño habitualmente se sobreestima, lo que indica una adaptación a un sueño ineficiente. Debido a las características de estos pacientes es importante mantener un control de sus parámetros bioquímicos, que también tienen un impacto en la calidad del sueño.

Introduction: In patients with chronic kidney disease (CKD) and specifically with renal replacement therapy (RRT), their circadian cycle and consequently their sleep quality are affected. Objective: To evaluate the quality of sleep in patients with chronic kidney disease attends at the nephrology service. Methods: Comparative study in patients with chronic kidney disease from the nephrology service classified into three groups, two of them had renal replacement therapy (peritoneal dialysis and hemodialysis) and one without renal replacement therapy (predialysis). For the quality of sleep we used the Pittsburgh Scale, sociodemographic data and biochemical parameters were included. Comparison of frequencies with chi-square, means with Student's t and Anova of one factor. Results: Three groups were formed: hemodialysis (n = 75), peritoneal dialysis (n = 58) and predialysis (n = 71). The mean age was 53.5 years; the subjective quality of sleep was "good" in 48.0% of the total and in 54.9% of predialysis patients (p <0.05). When applying the Pittsburgh scale, 80.4% of the total and 84.5 of the dialysis patients reported a "poor" quality of sleep. Of the seven dimensions evaluated, two were different in the three groups (p < 0.05) Conclusions: The patient's perception of the quality of sleep is regularly overestimated, which indicates an adaptation to this dream habit. Due to the characteristics of these patients, it is important to keep a check on their biochemical parameters, which also have an impact on the quality of sleep.

Una mirada a la Nefrogeriatría desde la Atención Primaria de Salud / An Approach to Geriatric Nephrology from Primary Health Care

Estimado director: A nivel mundial se observan varias realidades que desde el campo de las Ciencias Médicas debemos valorar: una población envejecida que se incrementa considerablemente, un aumento de estos pacientes con enfermedades crónicas no trasmisibles a expensas de diabetes mellitus e hipertensión arterial, presencia de más de una enfermedad en un mismo paciente, principalmente enfermedad cardiovascular, incremento sostenido de los pacientes con enfermedad renal crónica (ERC), muchos de los cuales requieren tratamientos renales de reemplazo (TRR) o trasplante renal y, a pesar de ello, subregistro de la enfermedad, situación de la que no escapa Cuba. La Nefrogeriatría se ha comenzado a estudiar recientemente, por lo que existen...(AU)

Conventional physical examination extended by bedside ultrasound: a new paradigm in nephrological practice / Exame físico convencional estendido pela ultrassonografia à beira do leito: novo paradigma da prática nefrológica

ABSTRACT Point-of-Care Ultrasound (POCUS) has been gaining momentum as an extension to physical examination in several specialties. In nephrology, POCUS has generally been used in a restricted way in urinary tract evaluation. We report the case of a patient with nephrotic syndrome secondary to amyloidosis, previously diagnosed by renal biopsy, who was oligosymptomatic when seen the an outpatient clinic, where the POCUS, focused on the heart, lung and abdomen, revealed anasarca, pulmonary congestion and cardiac changes suggestive of cardiac amyloidosis. After evaluation by the cardiology and hematology services, the diagnosis of AL amyloidosis with cardiac involvement was confirmed. This case emphasizes the importance of extending the physical examination using POCUS, which, ideally, should not be restricted to the urinary tract.

RESUMO A ultrassonografia Point of Care (POCUS) vem ganhando momentum como uma extensão ao exame físico em várias especialidades. Na nefrologia, a POCUS tem sido geralmente utilizada de forma restrita na avaliação do trato urinário. Relatamos o caso de uma paciente com síndrome nefrótica secundária à amiloidose previamente diagnosticada por biópsia renal, que se apresentava oligossintomática quando atendida em ambulatório, onde a POCUS, com foco no coração, pulmão e abdômen, revelou anasarca, congestão pulmonar e alterações cardíacas sugestivas de amiloidose cardíaca. Após avaliação pelos serviços de cardiologia e hematologia, foi confirmado o diagnóstico de amiloidose AL com envolvimento cardíaco. Esse caso enfatiza a importância da extensão do exame físico pela POCUS, que, idealmente, não deve se restringir ao trato urinário.

Consensus on the standard terminology used in the nutrition care of adult patients with chronic kidney disease / Consenso sobre a terminologia padronizada do processo de cuidado em nutrição para pacientes adultos com doença renal crônica

Abstract This nutrition consensus document is the first to coordinate the efforts of three professional organizations - the Brazilian Association of Nutrition (Asbran), the Brazilian Society of Nephrology (SBN), and the Brazilian Society of Parenteral and Enteral Nutrition (Braspen/SBNPE) - to select terminology and international standardized tools used in nutrition care. Its purpose is to improve the training delivered to nutritionists working with adult patients with chronic kidney disease (CKD). Eleven questions were developed concerning patient screening, care, and nutrition outcome management. The recommendations set out in this document were developed based on international guidelines and papers published in electronic databases such as PubMed, EMBASE(tm), CINHAL, Web of Science, and Cochrane. From a list of internationally standardized terms, twenty nutritionists selected the ones they deemed relevant in clinical practice involving outpatients with CKD. The content validity index (CVI) was calculated with 80% agreement in the answers. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework was used to assess the strength of evidence and recommendations. A total of 107 terms related to Nutrition Assessment and Reassessment, 28 to Diagnosis, nine to Intervention, and 94 to Monitoring and Evaluation were selected. The list of selected terms and identified tools will be used in the development of training programs and the implementation of standardized nutrition terminology for nutritionists working with patients with chronic kidney disease in Brazil.

Resumo Este consenso representa a primeira colaboração entre três organizações profissionais com foco em nutrição: Associação Brasileira de Nutrição (Asbran), Sociedade Brasileira de Nefrologia (SBN) e Sociedade Brasileira de Nutrição Parenteral e Enteral (Braspen/SBNPE), com o objetivo de identificar a terminologia e instrumentos padronizados internacionalmente para o processo de cuidado em nutrição. O foco é facilitar a condução de treinamentos de nutricionistas que trabalham com pacientes adultos com doenças renais crônicas (DRC). Foram levantadas onze questões relacionadas à triagem, ao processo de cuidado e à gestão de resultados em nutrição. As recomendações foram baseadas em diretrizes internacionais e em bancos de dados eletrônicos, como PubMed, EMBASE(tm), CINHAL, Web of Science e Cochrane. A partir do envio de listas de termos padronizados internacionalmente, vinte nutricionistas especialistas selecionaram aqueles que consideraram muito claros e relevantes para a prática clínica com pacientes ambulatoriais com DRC. Foi calculado o Índice de Validade de Conteúdo (IVC), com 80% de concordância nas respostas. O Grading of Recommendations, Assessment, Development and Evaluation (GRADE) foi usado para atribuir força de evidência às recomendações. Foram selecionados 107 termos de Avaliação e Reavaliação, 28 de Diagnóstico, 9 de Intervenção e 94 de Monitoramento e Aferição em Nutrição. A lista de termos selecionados e identificação de instrumentos auxiliará no planejamento de treinamentos e na implementação de terminologia padronizada em nutrição no Brasil, para nutricionistas que trabalham com pacientes renais crônicos.

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.

Point-of-care ultrasonography in nephrology: a cross-sectional national survey among Brazilian nephrologists / Ultrassonografia point-of-care em nefrologia: uma pesquisa nacional transversal entre nefrologistas brasileiros

Abstract Introduction: Point-of-care ultrasonography (US) (POCUS) has been used in several specialties, particularly in medical emergency. Despite the confirmation of its numerous benefits, the use of POCUS is still timid in nephrology. In the present study, we aim to investigate the use of POCUS by Brazilian nephrologists. Methods: A survey carried out among the members of the Brazilian Society of Nephrology, through institutional e-mail, using the SurveyMonkey platform. We included 12 self-administered questions, which answers were given anonymously. Results: It was evident that the majority (64%) of the participants did not have the opportunity to practice US during their nephrological training in their residency, specialization, or even in internships; those with experience with US use the method mainly for implanting central vascular accesses (68%), performing a renal biopsy (58%) and evaluating renal morphology (50%); and the main barriers for nephrologists who do not yet use US are the high price of US machines (26%) and the lack of time to learn about US (23%). Also, POCUS use for examinations of other organs, such as the lung (31%) and heart (18%), which are fundamental in the cardiovascular and volume assessment of patients with kidney diseases, is even more limited. However, 95% of the participants expressed an interest in learning POCUS for use in their medical practice. Conclusion: Most of the Brazilian nephrologists interviewed were not trained in US; however, almost all of the research participants expressed an interest in learning to use POCUS in nephrological practice.

Resumo Introdução: A ultrassonografia (US) pointof-care (POCUS) tem sido utilizada emvárias especialidades, particularmente na urgência médica. Apesar da constatação de seus numerosos benefícios, a utilização da POCUS ainda é tímida na nefrologia. No presente estudo, objetivamos fazer um levantamento sobre a utilização da POCUS pelos nefrologistas brasileiros. Métodos: Levantamento realizado entre os sócios da Sociedade Brasileira de Nefrologia, por meio do e-mail institucional, utilizando a plataforma SurveyMonkey. Foram incluídas 12 perguntas autoadministradas, cujas respostas se deram de forma anônima. Resultados: Ficou evidente que a maioria (64%) dos participantes não teve oportunidade de praticar a US durante sua formação nefrológica na residência, especialização ou mesmo em estágios; que aqueles com experiência com a US usam o método, principalmente, para implantação de acesso vascular central (68%), realização de biópsia renal (58%) e avaliação da morfologia renal (50%); e que as principais barreiras para os nefrologistas que ainda não utilizam a US são o preço elevado das máquinas de US (26%) e a falta de tempo para aprender sobre US (23%). Além disso, o uso da POCUS para exames de outros órgãos, como pulmão (31%) e coração (18%), fundamentais na avaliação cardiovascular e volêmica dos pacientes com doenças renais, ainda é mais limitado. Porém, 95% dos participantes expressaram interesse em aprender a POCUS para aplicação na sua prática médica. Conclusão: A maioria dos nefrologistas brasileiros entrevistados não foi treinada em US, contudo, a quase totalidade dos participantes da pesquisa manifestou interesse em aprender a utilizar a POCUS na prática nefrológica.

Vacunación sublingual con bacterias inactivadas en pacientes nefrológicos con infección urinaria recurrente: experiencia en un centro de España / Sublingual vaccination with inactivated bacteria in recurrent urinary tract infection of nephrologic patients: experience in a center in Spain

Resumen Introducción: las infecciones del tracto urinario (ITU) son frecuentes en pacientes con enfermedad renal crónica (ERC). Una opción de tratamiento cuando estas infecciones son recurrentes es la vacunación bacteriana sublingual. Objetivo: determinar la respuesta a la vacunación bacteriana sublingual en pacientes nefrológicos con ITU recurrente. Materiales y métodos: estudio cuasi experimental en el que se evaluó la evolución en 15 meses de los pacientes con ITU recurrente que asistieron a consulta externa de nefrología. Tras recibir tratamiento antibiótico según antibiograma para cada ITU, los participantes tomaron un ciclo de la vacuna sublingual bacteriana Uromune® durante tres meses. Se recogieron datos sociodemográficos y sobre factores de riesgo asociados, análisis de sangre y orina, episodios de ITU en los seis meses previos y posteriores, microorganismos causantes, tratamiento antibiótico concomitante, respuesta al tratamiento y resolución de la ITU. Resultados: se incluyeron 26 pacientes (80,8 % mujeres) con una media de edad de 61,9±18,4 años, de los cuales el 46,2 % tenía diabetes y el 47,7 %, afectación de la función renal. La media de ITU fue 3,62±1,77 (rango: 1 -7) antes de la vacuna y de 1,69±1,77 (rango: 0-5) después. Se recogieron 184 urocultivos: 74,9 % positivos, 16,9 % negativos y 8,2 % contaminados. Las bacterias más frecuentes fueron Escherichia coli (55,4 %), Enterococcus faecalis (6 %) y Enterobacter cloacae (2,7 %). El 50 % de los participan- tes presentó síndrome miccional, que se asoció inversamente con la edad (p<0,05). El 26,9 % no volvió a tener ITU y el 73,1 % tuvo menos episodios. Los pacientes con ERC avanzada (estadios IV-V) respondieron peor a la vacuna (92,9 % vs 50 %, p=0,025). Conclusiones: la vacunación bacteriana sublingual es una buena opción de tratamiento para la ITU recurrente de pacientes con ERC, siendo más eficaz en los que presentan mejor función renal.

Abstract Introduction: Urinary tract infections (UTIs) are common in patients with chronic kidney disease. A treatment option in recurrent UTI is sublingual bacterial vaccination. The objective of this study was to determine the response to vaccination in nephrologic patients with recurrent UTI. Method: Quasi-experimental study before-after (15 months) in patients with recurrent UTI from the outpatient nephrology consultation. After receiving antibiotic treatment for each UTI, patients took one cycle of the sublingual bacterial vaccine Uromune? for three months. Sociodemographic data, associated risk factors, analysis, UTI in the previous and subsequent six months, microorganisms, concomitant antibiotic treatment, response to treatment and resolution of UTI were collected. Results: Twenty-six patients (80.8% female) of 61.9 ±18.4 years, 46.2% with diabetes and 47.7% with impaired renal function were included. The episodes of UTI were 3.62 ±1.77 (1-7) before and 1.69 ± 1.77 (0-5) after vaccination. In total, 184 urine cultures were collected: 74.9% positive, 16.9% negative and 8.2% contaminated. The most frequent bacteria were Escherichia coli (55.4%), Enterococcus faecalis (6%) and Enterobacter cloacae (2.7%). Fifty percent had voiding syndrome, which was inversely associated with age (p < 0.05); 26.9% did not have a UTI again and 73.1% had fewer episodes. Patients with advanced chronic disease (stages 4-5) reponded worse to the vaccine (92.9% vs 50%, p =0.025). Conclusions: Sublingual bacterial vaccination is a good treatment option in recurrent UTI of nephrologic patients, being more effective in those with better renal function.
