Diagnostic approach and monitoring of chronic kidney disease in the primary care pediatric population / Abordaje diagnóstico y seguimiento de la enfermedad renal crónica en la población pediátrica desde la atención primaria en salud

Abstract Chronic kidney disease (CKD) has severe consequences on the quality and expectancy of life and is considered a major health problem worldwide. This is, especially relevant in pediatric patients, as they have unique characteristics and a mortality rate 30 times higher (in advanced stages) than healthy people. This review aims to define the minimum components for the diagnostic approach and monitoring of CKD in the pediatric population from primary health care to promote comprehensive care and adequate risk management. For this purpose, we performed a systematic review of the literature with a panel of experts. Based on the evidence, to optimize the definition, diagnosis, and timely treatment of CKD in the pediatric population, we formulated 21 recommendations. These were approved by the research team and peer-reviewed by clinical experts. They will facilitate the definition of the diagnostic approach for CKD in the pediatric population in primary health-care settings, allowing for timely treatment intervention, comprehensive care, and monitoring of this disease.

Frequency of skin diseases in renal transplant recipients and patients with chronic kidney disease in a tertiary center: a cross-sectional study

ABSTRACT BACKGROUND: The prevalence of chronic kidney disease (CKD) has increased in the recent decades, along with the number of patients in the terminal stages of this disease, requiring transplantation. Some skin disorders are more frequent in patients with CKD and in renal transplant recipients (RTR). OBJECTIVES: To evaluate the frequency of skin diseases in RTR and patients with CKD receiving conservative treatment. DESIGN AND SETTING: This observational cross-sectional study recruited consecutive patients with CKD and RTR from a nephrology clinic at a teaching hospital in Brazil between 2015 and 2020. METHODS: Quantitative, descriptive, and analytical approaches were used. The sample was selected based on convenience sampling. Data were collected from dermatological visits and participants' medical records. RESULTS: Overall, 308 participants were included: 206 RTR (66.9%, median age: 48 years, interquartile range [IQR] 38.0-56.0, 63.6% men) and 102 patients with CKD (33.1%, median age: 61.0 years, IQR 50.0-71.2, 48% men). The frequency of infectious skin diseases (39.3% vs. 21.6% P = 0.002) were higher in RTR than in patients with CKD. Neoplastic skin lesions were present in nine (4.4%) RTR and in only one (1.0%) patient with CKD. Among the RTR, the ratio of basal cell carcinoma to squamous cell carcinoma was 2:1. CONCLUSIONS: This study revealed that an increased frequency of infectious skin diseases may be expected in patients who have undergone kidney transplantation. Among skin cancers, BCC is more frequently observed in RTR, especially in those using azathioprine.

Validação das equações para estimativa da filtração glomerular ajustáveis por raça/cor em adultos de Vitória, Espírito Santo, Brasil / Validation of glomerular filtration estimation equations adjustable by race/colour in adults from Vitória, Espírito Santo, Brazil

Resumo A avaliação da função renal é feita por meio da taxa de filtração glomerular (TFG), que pode ser determinada pelo clearance de creatinina (CrCl) e é dependente da coleta urinária de 24 horas (h), o que dificulta o seu uso na atenção primária. As equações que estimam a TFG a partir da creatinina sérica tornam o exame mais acessível, contudo, os seus ajustes por raça/cor têm sido questionados em populações miscigenadas. Para verificar a concordância entre o ClCr e a TFG estimada por fórmulas (Modification of Diet in Renal Disease [MDRD-4] e Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI]), com ou sem ajuste por raça/cor, foram utilizados dados de subestudo da Pesquisa Nacional de Saúde (PNS) com inclusão de 272 adultos de Vitória, Espírito Santo, que fizeram coleta urinária de 24h. Adotou-se análise de variância (ANOVA) e método de Bland-Altman. Houve concordância adequada entre o ClCr e as equações, mas o ajuste por raça/cor diminui a acurácia destas últimas. No fator raça/cor, houve semelhança entre grupos para o ClCr (p=0,21) sugerindo não haver diferença no metabolismo da creatinina em função da cor da pele. Conclui-se que MDRD-4 e CKD-EPI apresentam desempenho satisfatório na avaliação da função renal, não sendo recomendado o uso de correções para raça/cor.

Abstract The assessment of renal function is performed using the glomerular filtration rate (GFR) whose measurement by creatinine clearance (ClCr) and is dependent on a 24-hour urine sample, hindering it use in primary healthcare. The equations that estimate GFR from serum creatinine make the test more accessible, however, their adjustments by race/color have been questioned in mixed populations. To test the agreement between CrCl and GFR estimated by formulas (Modification of Diet in Renal Disease [MDRD-4] and Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI]), with or without adjusting for race/color, data were used from a sub-study of the National Health Survey (NHS) including 272 adults from Vitória/Espírito Santo who underwent a 24-hour urinary sampling. Analysis of variance (ANOVA) and the Bland-Altman method were adopted. There was adequate agreement between ClCr and equations, but the adjustment by race/color decreases the accuracy of both equations. In the race/color factor, there was similarity between groups for CrCl (p=0.21), suggesting that there is no difference in creatinine metabolism induced by skin color. It is concluded that MDRD and CKD-EPI equations perform satisfactorily in the evaluation of renal function, and the use of corrections for race/color is not recommended.

Síndrome cardiorrenal tipo 4 en paciente revascularizado percutáneamente

Introducción: el síndrome cardiorrenal es una patología dada por la disfunción en la interdependencia de estos órganos por interacciones bidireccionales (agudas o crónicas), los cuales pueden afectar indistintamente la función renal o ventricular. Objetivo: presentar y justificar la enfermedad renal crónica como desencadenante de cuadros congestivos por falla cardiaca de novo. Presentación del caso: se reporta el caso de un paciente masculino de 69 años revascularizado percutáneamente hace tres años con múltiples comorbilidades que ingresa en el contexto de una falla cardiaca de novo, secundaria a su enfermedad renal crónica estadio V de base, en manejo con hemodiálisis y en quien se descartó enfermedad coronaria aguda y miocardiopatía infiltrativa. Se logró estabilizar la injuria renal y cardiaca dando egreso y continuando manejo ambulatorio de sus patologías, al llevar un control adecuado de las mismas con Nefrología y Cardiología. Discusión y conclusión: la enfermedad cardiovascular generada por antecedentes renales tiene una gran repercusión en la función ventricular izquierda, causando hipertrofia, lo que lleva a una congestión con posterior sobrecarga debido a la caída del filtrado glomerular y que resulta en la disminución de la fracción de eyección. La enfermedad renal crónica predispone a alteraciones en la función cardiaca, lo que aumenta el riesgo cardiovascular.

Background: Cardiorenal syndrome is a pathology caused by dysfunction in the interdependence of these organs due to bidirectional interactions (acute or chronic), which can affect either renal or ventricular function. Purpose: To present and justify chronic kidney disease as a trigger of congestive conditions due to de novo heart failure. Case presentation: We report the case of a 69-year-old male patient percutaneously revascularized 3 years ago with multiple comorbidities who was admitted in the context of de novo heart failure secondary to his stage V chronic kidney disease on hemodialysis, in whom acute coronary artery disease and infiltrative cardiomyopathy were ruled out. The renal and cardiac injury was stabilized and the patient was discharged and continued outpatient management of his pathologies with adequate control of the same with nephrology and cardiology. Discussion and conclusion: Cardiovascular disease generated by renal history has great repercussion in left ventricular function causing hypertrophy that leads to congestion with subsequent overload due to the fall of glomerular filtration resulting in a decrease of the ejection fraction. Chronic kidney disease predisposes to alterations in cardiac function increasing cardiovascular risk.

Nefrectomía totalmente laparoscópica para donante vivo de riñón: Características y desenlaces en una institución de alta complejidad en Colombia. Serie de casos / Total laparoscopic nephrectomy for a living kidney donor: Characteristics and outcomes in a single center from Colombia. Case series

Introducción. El trasplante es la mejor opción de tratamiento para los pacientes con enfermedad renal terminal, sin embargo, existe discrepancia entre las listas de espera y la disponibilidad de órganos a partir de la donación cadavérica. Buscando aumentar el número de órganos disponibles se implementó el trasplante con donante vivo. A partir de la introducción de técnicas mínimamente invasivas para la nefrectomía, el donante vivo ha logrado cifras cercanas al 50 % de los trasplantes realizados en muchas instituciones, debido a los beneficios propios del procedimiento. El objetivo de este estudio fue describir los resultados después de la incorporación del procedimiento totalmente laparoscópico en nuestra institución. Métodos. Se hizo un análisis retrospectivo de las características de los pacientes llevados a nefrectomía para obtención de injerto por técnica totalmente laparoscópica y los resultados en un solo centro en Cali, Colombia, desde noviembre de 2019 hasta octubre de 2022. Los datos fueron obtenidos mediante la revisión de las historias clínicas electrónicas. Resultados. Se realizaron 78 nefrectomías para obtención de injerto con técnica totalmente laparoscópica. El tiempo operatorio promedio fue de 152 minutos, el sangrado promedio fue de 12 ml, la estancia hospitalaria promedio del donante fue de 2,8 días. La tasa de complicaciones fue de 7,6 % (4 pacientes con complicación Clavien-Dindo I y 2 pacientes Clavien-Dindo IIIb). No se presentó ningún caso de mortalidad. Conclusiones. La técnica totalmente laparoscópica resulta ser una técnica segura con baja tasa de morbilidad y excelentes beneficios para los donantes.

Introduction. Kidney transplant is the best treatment option for end-stage renal disease. However, the discrepancy between waiting lists and the availability of organs from cadaveric donation is well known. Organ transplantation with a living donor was implemented to increase the number of organs available. Since the introduction of minimally invasive techniques for nephrectomy, living donors have achieved figures close to 50% of transplants performed in many institutions due to the procedure's benefits. In our country, the experiences described are from the hand-assisted technique. This is the first description after incorporating the laparoscopic procedure. Methods. A retrospective analysis of the characteristics and results of all patients undergoing nephrectomy to obtain a graft using a laparoscopic technique was carried at a single center in Cali, Colombia, from November 2019 to October 2022. The electronic medical records were reviewed to obtain the data. Results. Seventy-eight nephrectomies were performed to obtain a graft with a laparoscopic technique. The mean operating time was 152 minutes, the average bleeding was 12 cc, and the average hospital stay was 2.8 days. The complication rate was 7.6% (four patients with Clavien-Dindo I complication and two Clavien-Dindo IIIb patients). There were no cases of mortality. Conclusions. The laparoscopic technique is safe, with a low morbidity rate and excellent benefits.

Traducción y adaptación transcultural del instrumento Kidney Disease Questionnaire (KDQ) para la evaluación de calidad de vida en pacientes con enfermedad renal crónica en Colombia

Contexto: dada la importancia de incorporar la calidad de vida durante la atención de los pacientes con enfermedad renal crónica (ERC), es necesario disponer de versiones traducidas y adaptadas transculturalmente de diferentes instrumentos diseñados para la medición de este constructo. Objetivo: traducir y adaptar transculturalmente al español hablado en Colombia el instrumento Kidney Disease Questionnaire (KDQ), para medir la calidad de vida en pacientes con ERC en insuficiencia renal. Metodología: el proceso se llevó a cabo siguiendo la metodología propuesta por la Eortc, que incluye traducciones directas, traducciones inversas y una prueba piloto llevada a cabo en un grupo de pacientes con diagnóstico de ERC en diálisis, atendidos en unidades renales de Baxter Renal Care Services®, en Bogotá, Colombia. Resultados: en el proceso se identificaron (I) casos que requirieron de consenso para seleccionar la traducción que mejor conservaba el significado y la equivalencia semántica del instrumento, (II) diferencias en la sintaxis o uso de paráfrasis, (III) se consideró pertinente realizar algunos cambios mínimos en el uso o la disposición de preposiciones o artículos, con el fin de que los ítems y las opciones de respuesta se leyeran de una manera más natural. Los cambios más notorios fueron en los ítems 18, 19 y 21, en los que para una mejor compresión de la pregunta, se identificó la necesidad de agregar determinadas expresiones o palabras. Conclusiones: se tiene disponible la versión traducida al español y adaptada culturalmente a la población colombiana del KDQ. El siguiente paso a fin de utilizar el instrumento en el país, es disponer de evidencia sobre sus propiedades clinimétricas.

Background: Considering the importance of incorporating quality of life during the care of patients with chronic kidney disease (CKD), it is necessary to have translated and cross-culturally adapted versions of different instruments designed to measure this construct. Purpose: To translate and cross-culturally adapt the Kidney Disease Questionnaire (KDQ) instrument for measuring quality of life in patients with CKD in renal failure to the Spanish spoken in Colombia. Methodology: The process was carried out following the methodology proposed by the EORTC, which includes direct translations, reverse translations and pilot test carried out in a group of patients with a diagnosis of CKD on dialysis, attended in renal units of Baxter Renal Care Services ®, in Bogota, Colombia. Results: In the process, cases were identified that required consensus to select the translation that best preserved the meaning and semantic equivalence of the instrument; differences in syntax or use of paraphrases; it was considered pertinent to make some minimal changes in the use or arrangement of prepositions or articles, so that the items and answer options would read in a more natural way; the most notorious changes were in items 18, 19 and 21, in which for a better understanding of the question, the need to add certain expressions or words was identified. Conclusions: The Spanish translated version and culturally adapted to the Colombian population of the KDQ is now available. The next step in order to use the instrument in the country is to have evidence on its clinimetric properties.

Prevalence of Atrial Fibrillation in Patients With end Stage Renal Disease

Abstract Background Atrial fibrillation (AF) is the most common arrhythmia in patients with end-stage renal disease (ESRD). The coexistence of high thromboembolic and hemorrhagic risks, added to the lack of strong scientific evidence on the safety of anticoagulants in the setting of renal failure, makes this a clinically challenging situation. Objectives To describe the clinical-demographic profile and prevalence of AF in the population with ESRD undergoing dialysis. Secondary objectives include the assessment of thromboembolic (CHA2DS2VASC) and bleeding (HASBLED) risk scores. Methods Cross-sectional analytical-descriptive study, carried out between January and March 2020. Patients with ESRD were evaluated by means of a medical history questionnaire, physical examination, and 12-lead electrocardiogram. A chi-square (χ2) association test was applied to calculate association between clinical variables and AF, with a significance level of α = 0.05. Results This study evaluated 295 patients, most of whom were men (170), elderly (63, IQR 53-71), current smokers (130), with associated cardio-endocrine comorbidities. The prevalence of AF was 6.7% (20). Heart failure (HF) (χ2=15.417; p<0.001), age of 65 years or older (χ2=14.584; p<0.001), and anticoagulation (χ2=5.715; p<0.01) were associated with AF. The median CHA2DS2VASC and HASBLED was 4 and 3, respectively. Eight patients were taking warfarin and five were receiving apixaban. Conclusion The prevalence of AF in this study is similar to that reported in other published articles on the subject, and patients were at high risk for cardiovascular outcomes. Non-anticoagulation strategy was commonly adopted due to controversies in the literature as well as the absence of published randomized clinical trials.

Evolución clínica del tratamiento empírico versus dirigido de la infección relacionada a catéter de hemodiálisis

RESUMEN Introducción: las infecciones relacionadas a catéteres utilizados en hemodiálisis constituyen una de las causas de morbimortalidad más frecuentes. No se dispone de estudios previos en el Paraguay que demuestren la diferencia entre tratamiento empírico y dirigido de infección relacionada a catéter de hemodiálisis Objetivo: determinar la evolución clínica del tratamiento empírico de la infección relacionada a catéter versus el tratamiento dirigido en pacientes adultos. Material y métodos: se aplicó un diseño observacional, retrospectivo, de corte transversal que incluyó 128 pacientes internados en el Hospital Nacional, Itauguá, Paraguay, durante los años 2020 y 2021. Fueron divididos en grupos de tratamiento dirigido (64 pacientes) y empírico (64 pacientes). Resultados: la edad media fue 52 ± 14 años. El acceso vascular yugular fue el más utilizado (78,91%). Se observó que el transcurso de días entre la colocación de catéter de hemodiálisis hasta su infección fue 16 ± 7,6 días. El crecimiento microbiano predominante en ambos grupos fue de cocos gram positivos (84,37%). S. aureus se aisló en 84,31% del grupo tratamiento dirigido y en 15,68% del grupo con tratamiento empírico. El grupo antibiótico más utilizado en ambos grupos fueron los glucopéptidos (77,34%) y la combinación más utilizada fue ciprofloxacina con vancomicina tanto en el grupo dirigido (37,5%) como en el empírico (31,25%). El desenlace curación de infección se observó en 90,62% en el grupo de tratamiento empírico y en 82,81% en el grupo dirigido. La frecuencia de sepsis fue 17,18% en el grupo empírico y 32,8% en grupo dirigido. La mortalidad fue 9,37% en grupo empírico y 14,06% en grupo dirigido. Conclusión: el germen más prevalente fue S. aureus. La curación de infección relacionada a catéter fue más frecuente en el grupo empírico, la mortalidad y sepsis predominaron en el grupo dirigido.

ABSTRACT Introduction: Infections related to catheters used in hemodialysis are one of the most frequent causes of morbidity and mortality. There are no previous studies in Paraguay that demonstrate the difference between empirical and directed treatment of hemodialysis catheter-related infection. Objective: To determine the clinical course of empirical treatment versus targeted treatment of catheter-related infection in adult patients. Material and methods: An observational, retrospective, cross-sectional design was applied including 128 patients admitted to the Hospítal Nacional of Itauguá, Paraguay, during the years 2020 and 2021. They were divided into directed (64 patients) and empirical (64 patients) treatment groups. Results: The mean age was 52 ± 14 years. The jugular vascular access was the most used (78.91%). It was observed that the time between hemodialysis catheter placement and infection was 16±7.6 days. The predominant microbial growth in both groups was gram-positive cocci (84.37%). S. aureus was isolated in 84.31% of the directed treatment group and in 15.68% of the empirical treatment group. The most used antibiotic group in both groups were glycopeptides (77.34%) and the most used combination was ciprofloxacin with vancomycin, both in the targeted group (37.5%) and in the empirical group (31.25%). The outcome of infection cure was observed in 90.62% in the empirical treatment group and in 82.81% in the directed group. The frequency of sepsis was 17.18% in the empirical group and 32.8% in the directed group. Mortality was 9.37% in the empirical group and 14.06% in the directed group. Conclusion: The most prevalent germ was S. aureus. Cure of catheter-related infection was more frequent in the empiric group, while mortality and sepsis predominated in the directed group.

Complicaciones de la endocarditis infecciosa al momento del diagnóstico y su relación con los gérmenes aislados en pacientes adultos

RESUMEN Introducción: la endocarditis infecciosa es una enfermedad de una variada presentación clínica. Es cada vez más frecuente debido a los cuidados relacionados con la salud. Objetivo: determinar las complicaciones de los pacientes con endocarditis infecciosa bacteriana al momento del diagnóstico y su relación con el agente causal y ofrecer una descripción general de las características demográficas y clínicas presentes en pacientes del Hospital Nacional, Itauguá, Paraguay, en el periodo 2017-2021. Material y métodos: estudio descriptivo, observacional, retrospectivo que incluyo 37 pacientes con el diagnóstico de endocarditis infecciosa con germen aislado. Resultados: la edad media fue 45 ±14 años, la mayoría provenía del área urbana y era del sexo masculino (65%). La comorbilidad más frecuente fue enfermedad renal crónica (50%). Los procedimientos invasivos (catéter venoso central simple) fueron el foco de bacteriemia más frecuente (65,22%). La válvula más comprometida fue la aórtica, la complicación más frecuente fue la insuficiencia cardiaca (70,27%), hubieron 49% de desenlaces fatales. El germen más frecuente y causante de la mayor morbimortalidad fue Staphylococcus aureus (43,24%). Conclusión: la enfermedad renal crónica fue el principal factor de riesgo. Ser portador de catéter venoso simple de hemodiálisis estuvo relacionado al aislamiento del Staphylococcus aureus como agente causal más frecuente. Este germen estuvo relacionado a la alta tasa de complicaciones al momento del ingreso y con el alto porcentaje de desenlaces fatales.

ABSTRACT Introduction: Infective endocarditis is a disease with a varied clinical presentation. It is becoming more frequent due to health-related care. Objective: To determine the complications of patients with bacterial infective endocarditis at the time of diagnosis and their relationship with the causal agent and offer a general description of the demographic and clinical characteristics present in patients of the Hospital Nacional of Itauguá, Paraguay, in the period 2017- 2021. Material and methods: Descriptive, observational, retrospective study that included 37 patients diagnosed with infective endocarditis with isolated germ. Results: The mean age was 45±14 years, the majority came from the urban area and was male (65%). The most frequent comorbidity was chronic kidney disease (50%). Invasive procedures (simple central venous catheter) were the most frequent source of bacteremia (65.22%). The most compromised valve was the aortic, the most frequent complication was heart failure (70.27%) and there was 49% of fatal outcomes. The most frequent germ and cause of the highest morbidity and mortality was Staphylococcus aureus (43.24%). Conclusion: Chronic kidney disease was the main risk factor. Being a carrier of a simple venous hemodialysis catheter was related to the isolation of Staphylococcus aureus as the most frequent causal agent. This germ was related to the high rate of complications at the time of admission and the high percentage of fatal outcomes.

Treatment of acquired perforant dermatoses with allopurinol / Tratamento de dermatose perfurante adquirida com alopurinol

Perforating dermatoses are papulonodular cutaneous pathologies characterized by transepithelial extrusion of components of the extracellular matrix of the dermis, by inflammation or degeneration. When secondary, the systemic diseases are called Acquired Perforating Diseases. Our letter aims to report a case of acquired perforating dermatoses secondary to chronic renal dialysis. The treatment with Allopurinol proved to be effective in this case. Allopurinol would act as an antioxidant, reducing the inflammatory reaction in tissues and consequent damage to the collagen fibers (AU)

Objetivo verificar os fatores relacionados aos desfechos clínicos e à sobrevida de doentes renais crônicos em tratamento hemodialítico em uma clínica do sul de Santa Catarina. Método Estudo de coorte retrospectivo. A sobrevida foi avaliada por curvas de Kaplan-Meier e os fatores relacionados ao desfecho, por meio de regressão de Cox, expressos por meio do Hazard Ratio (HR) e intervalo de confiança de 95%. Resultados Entre 120 pacientes, a média de idade foi de 61,8 (±13,9) anos. O principal encaminhamento para hemodiálise foi do nefrologista (33,3%). As principais doenças de base identificadas foram hipertensão arterial (60,8%) e Diabetes Mellitus (29,2%). Foi registrado óbito em 44,2% dos pacientes e sete (5,8%) realizaram transplante. A sobrevida diminuiu de 76,1% em um mês para 49,3% em um ano de tratamento. Encaminhamentos pela UTI (HR 18,1 IC95% 4,49-72,8) e pela Unidade Básica de Saúde (HR 9,27 IC95% 1,48-58,2) foram associados ao óbito, além de valores maiores de cálcio inicial (HR 2,36 IC95% 1,21-4,62) e menores de creatinina final (HR 0,69 IC95% 0,55-0,87). Conclusão O principal desfecho verificado foi o óbito, sendo a sobrevida dos pacientes, avaliada em curto prazo, abaixo do esperado, sugerindo encaminhamento tardio ao tratamento substitutivo.

Abstract Background Hemodialysis usually lasts until the end of life or until kidney transplantation. Objective to verify the factors related to clinical outcomes and survival of chronic renal patients in hemodialysis at a clinic in the south of Santa Catarina Method A retrospective cohort study. Survival was assessed by Kaplan-Meier curves and outcome-related factors were assessed using Cox regression, with comparisons using Hazard Ratio (HR) and 95% confidence intervals. Results Among the 120 patients, the mean age was 61.8 (± 13.9) years. The main sector of referral for hemodialysis was the nephrologist (33.3%). The main underlying diseases identified were hypertension (60.8%) and Diabetes Mellitus (29.2%). Death was recorded in 44.2% of the patients, and seven (5.8%) performed a transplant. Survival decreased from 76.1% in one month to 49.3% in one year of treatment. Referral by intensive care unit (HR 18.1 95% CI 4.49-72.8) and Basic Health Unit (HR 9.27 95% CI 1.48-58.2) were associated with death, besides of higher values of initial calcium (HR 2.36 95%CI 1.21-4.62) and lower final creatinine (HR 0.69 95%CI 0.55-0.87). Conclusion The main outcome was death, being the patient´s survival, evaluated in a short term, lower than expected, suggesting late referral to the substitutive treatment.

Immunoglobulin G4-related retroperitoneal fibrosis / Fibrosis retroperitoneal relacionada con IgG4

Abstract Some patients diagnosed with idiopathic retroperitoneal fibrosis could be reclassified as IgG4-related disease (IgG4-RD). Classification criteria have not been uniform and prevalence of IgG4-related retroperitoneal fibrosis (IgG4-RPF) is unknown in our region. We aimed to describe IgG4-RPF frequency relying on criteria published recently and comparing clinical, histopathologic and radiologic features with non-IgG4-RPF. From January, 2005 to December, 2020, nineteen adults with histopathologic diagnosis of idiopathic retroperitoneal fibrosis were included in a dynamic retrospective cohort at Hospital Italiano de Buenos Aires. Pathology slides were reviewed and immunohistochemistry was performed and assessed for each case. We used classification criteria described in 2019 American College of Rheumatology/European League Against Rheumatism to identify IgG4-RD cases. Ten of 19 patients met criteria for IgG4-RPF. Median age was similar in two subsets (61 versus 55, p = 0.2) and both had male predominance. Three out of 10 patients (p = 0.2) featured other manifestations of IgG4-RD in the IgG4-RPF group, and periaortic fibrosis was the most significant finding in images (p = 0.01). Corticosteroids were mostly used as therapy, followed by azathioprine and rituximab. Most patients did not receive specific treatment. IgG4-RPF patients had dense lymphocytic infiltrate and 8 out of 10 showed storiform fibrosis (p = 0.02). IgG4+ cells/hpf and IgG4/IgG ratio were significantly higher (p = 0.01). Over half of the patients in our cohort met the criteria of IgG4-RPF. New criteria may harmonize the identification of IgG4-RD. As IgG4-RD may be reversible at initial stages, these findings may lead to early recognition, treatment and integral follow-up.

Resumen Muchos pacientes con diagnóstico de fibrosis retroperitoneal idiopática (FRI) pueden ser reclasificados como enfermedad relacionada con IgG4 (ER- IgG4). Los criterios diagnósticos no han sido uniformes y la frecuencia de fibrosis retroperitoneal relacionada con IgG4 en nuestra región es desconocida. El objetivo fue describir la frecuencia de ER-IgG4 en pacientes clasificados como FRI y comparar características clínicas, histopatológicas y de laboratorio con aquellos que no reunían criterios de la enfermedad. Se incluyeron 19 adultos en un estudio de cohorte retrospectiva dinámica con diagnóstico anatomopatológico de FRI, en el Hospital Italiano de Buenos Aires, desde enero de 2005 hasta diciembre de 2020. Se revisaron las biopsias y se realizó inmun ohistoquímica en cada una. Se consideró caso al paciente que reunía los criterios de la American College of Rheumatology/European League Against Rheumatism 2019. Diez pacientes reunieron criterios de ER-IgG4. La mediana de edad fue similar en ambos grupos (61 vs. 55, p = 0.2) y en ambos hubo predominio masculino. Tres de 10 pacientes (p = 0.2) tuvieron otras manifestaciones de ER-IgG4 y la fibrosis periaórtica fue el hallazgo más significativo en los estudios por imágenes (p = 0.01). Los corticoides fueron las drogas más utilizadas seguidos por azatioprina y rituximab, pero la mayoría no reci bió tratamiento específico. Todos los pacientes con fibrosis retroperitoneal relacionada con IgG4 presentaron infiltrado linfocitario denso y 8/10 fibrosis estoriforme (p = 0.01), así como las células IgG4+/hpf y ratio IgG4/ IgG fueron significativamente mayores (p = 0.01). Más de la mitad de los pacientes con FRI cumplieron criterios de ER-IgG4. Los nuevos criterios diagnósticos podrían contribuir a homogeneizar la identificación de ER-IgG4. Dado que esta enfermedad puede ser reversible en estadios tempranos, estos resultados promueven aumentar el conocimiento de la entidad para tratamiento precoz y seguimiento integral.

Quality indicators for primary health care in chronic kidney disease in the public service of a city in the State of São Paulo, Brazil / Qualidade de atenção primária em doença renal crônica em um serviço público de um município do Estado de São Paulo, Brasil / Calidad de los cuidados de salud en la atención primaria relacionados con la enfermedad crónica de riñón en un servicio público en una ciudad del Estado de São Paulo, Brasil

Abstract: Complications of chronic kidney disease (CKD) can be avoided when promptly diagnosed and treated. The objective was to describe quality indicators of CKD detection and health care in the primary care public service of a city in the State of São Paulo, Brazil. This retrospective study analyzed charts of patients who attended primary care in the public service between November 2019 and February 2020. We selected 10 health quality indicators based on their scientific relevance and availability from the medical records that could express how CKD was identified and managed in primary health care. We estimated the adequate percentage of health indicators with data from 1,066 individuals who had ≥ one risk factor for CKD: hypertension, diabetes, or > 60 years old. Among patients, 79.4% had information on serum creatinine, whereas 58.8% were investigated for proteinuria. Blood pressure data were found in 98.9% of the records. The percentage of patients with blood pressure < 140x90mmHg, glycosylated hemoglobin < 6.5% and LDL-cholesterol < 100mg/dL was 79.2%, 49.2%, and 33.3%, respectively. Renin-angiotensin system blockers were prescribed to 82.8% of the patients with hypertension and CKD. Serum potassium was measured in 35.7% for those who were using renin-angiotensin system blockers. Among those people with CKD, 16.7% had CKD assigned in the medical records as a diagnose. Among those participants at higher risk for CKD, the referral rate to a nephrologist was 31.6%. This study confirmed some missed quality indicators of CKD in primary healthcare. Our results may help administrators develop public policies that improve health care for individuals at high risk for CKD. Long-term follow-up of the health indicators we proposed here will be useful to assess the impact of policy intervention.

Resumo: As complicações da doença renal crônica (DRC) podem ser evitadas quando a doença é diagnosticada e tratada oportunamente. O estudo teve como objetivo descrever a qualidade dos indicadores da detecção e assistência para a DRC no sistema púbico de saúde em um município do Estado de São Paulo, Brasil. O estudo retrospectivo analisou prontuários de pacientes que utilizaram serviços de atenção primária no sistema público entre novembro de 2019 e fevereiro de 2020. Selecionamos dez indicadores de qualidade com base na relevância científica e disponibilidade, a partir dos prontuários médicos. Calculamos o percentual de adequação com dados de 1.066 indivíduos que apresentavam ≥ 1 fatores de risco para DRC: hipertensão, diabetes ou idade > 60 anos. No total, 79,4% dos pacientes apresentavam informação sobre creatinina sérica, e 58,8% foram investigados para proteinúria. Dados de pressão arterial foram encontrados em 98,9% dos prontuários. As proporções de pacientes com pressão arterial < 140x90mmHg, hemoglobina glicada < 6,5% e LDL < 100mg/dL foram 79,2%, 49,2% e 33,3%, respectivamente. Os antagonistas do sistema renina-angiotensina foram prescritos em 82,8% dos pacientes com hipertensão e DRC. O potássio sérico foi medido em 35,7% dos pacientes em uso de antagonistas do sistema renina-angiotensina. Entre os indivíduos com DRC, 16,7% tinham esse diagnóstico registrado no prontuário médico. Entre os participantes com risco mais elevado de DRC, 31,6% foram encaminhados para um nefrologista. O estudo confirmou a falta de alguns indicadores de qualidade para DRC na assistência primária. Os resultados podem ajudar gestores a desenvolverem políticas públicas que melhorem a assistência para indivíduos com risco maior de DRC. O seguimento a longo prazo dos indicadores de saúde propostos aqui será útil para avaliar o impacto dessa política de intervenção.

Resumen: Las complicaciones de la enfermedad crónica de riñón (ECR) se pueden evitar cuando esta enfermedad se diagnostica con prontitud y se trata. El objetivo fue describir indicadores de calidad en la detección de ECR, así como la asistencia en el servicio público de una ciudad, en el Estado de São Paulo, Brasil. Este estudio retrospectivo analizó fichas de pacientes que acudían a atención primaria en el servicio público, entre noviembre 2019 y febrero 2020. Seleccionamos 10 indicadores de calidad en salud, basados en relevancia científica y disponibilidad de registros médicos. Calculamos el porcentaje de adecuación de ellos con datos de 1.066 personas que tenían ≥ 1 factor de riesgo ECR: hipertensión, diabetes, o > 60 años. Un 79,4% de los pacientes tenían información sobre la creatinina sérica, y se investigó a un 58,8% en el caso de la proteinuria. Los datos de presión sanguínea se encontraron en un 98,9% de los registros. El porcentaje de pacientes con presión sanguínea < 140x90mmHg, hemoglobina glicada < 6,5% y LDL < 100mg/dL fue 79,2%, 49,2%, y 33,3%, respectivamente. Se prescribieron bloqueadores del sistema renina-angiotensina a un 82,8% de los pacientes con hipertensión y ECR. Se midió el potasio sérico en un 35,7% de aquellos quienes estaban usando bloqueadores del sistema renina-angiotensina. Entre aquellas personas con ECR, 16,7% había ECR asignado en los registros médicos como diagnosis. Entre aquellos participantes en riesgo mayor por ECR, la tasa de derivación a un nefrólogo fue 31,6%. Este estudio confirmó algunos indicadores de calidad olvidados de ECR en los cuidados de salud en la atención primaria. Nuestros resultados quizás podrían ayudar a los gestores a desarrollar políticas públicas que mejoraran el cuidado de salud para las personas con alto riesgo de ECR. El seguimiento a largo plazo de los indicadores de salud que propusimos aquí será útil para evaluar el impacto de la política de intervención.

Transposição de veia femoral superficial como solução de acesso vascular para hemodiálise / Superficial femoral vein transposition as a solution for hemodialysis vascular access

Resumo O crescimento significativo do número de indivíduos dependentes de hemodiálise para terapia renal substitutiva e o uso irrestrito de cateteres de curta e longa permanência têm desafiado os cirurgiões vasculares em busca de soluções para a exaustão de acessos nos membros superiores e taxas crescentes de estenose venosa central nesses pacientes. Na impossibilidade do acesso em membros superiores, técnicas excepcionais podem ser utilizadas, e os membros inferiores são uma alternativa factível como sítio de acesso vascular para hemodiálise. Este artigo relata um caso de transposição de veia femoral superficial para confecção de uma fístula arteriovenosa em alça em um paciente sem possibilidade de acessos nos membros superiores, além de fazer uma revisão da literatura sobre essa técnica ainda pouco utilizada.

Abstract The significant growth in the number of individuals dependent on hemodialysis for renal replacement therapy and unrestricted use of short and long-term catheters have challenged vascular surgeons in search of solutions for patients whose options for access via the upper limbs have been exhausted and for the increasing rates of central venous stenosis in these patients. When access via the upper limbs is impossible, exceptional techniques can be used and the lower limbs offer feasible alternative vascular access sites for hemodialysis. This article reports a case of superficial femoral vein transposition to make a loop arteriovenous fistula in a patient with no possibility of access via the upper limbs and presents a literature review on this technique that remains little used.

Visceral adiposity indicators and cardiovascular risk in hemodialytic patients

ABSTRACT Objective: Cardiovascular diseases represent the main cause of death in chronic kidney disease (CKD). We aimed to evaluate the prevalence and association of the hypertriglyceridemia-waist phenotype (HWP) and visceral adiposity index (VAI) with cardiometabolic risk factors (CR) in patients with CKD on hemodialysis (HD). Materials and methods: The study is based on a cross-sectional design with 265 HD patients in two cities in northeastern Brazil. The VAI was calculated considering the variables body mass index (BMI), waist circumference (WC), triglycerides (TG) and high density lipoprotein cholesterol (HDL-c). HWP was defined as the concomitant elevation of WC and TG. The Poisson Regression Model with robust variance estimation was adjusted considering a hierarchical approach for explanatory variables. Prevalence ratios (PR) were also estimated. The level of significance adopted was 5%. Results: In our study HWP and VAI prevalence's were 29.82% and 58.49%, respectively. In the final model, there was an association between VAI and female gender (PR = 1.46; p < 0.0001) and high body fat (% BF) (PR = 1.33; p < 0.0019). HWP was associated with females (PR = 1.80; p = 0.002), alcohol consumption (PR = 1.58; p = 0.033), obesity (PR = 1.89; p = 0.0001), high %BF (PR = 1.76; p = 0.012) and reduced HDL-c (PR = 1.48; p = 0.035). Conclusion: The HWP stood out as the association with more CR factors, representing a promising method for tracking cardiometabolic risk in HD patients, mainly female.

It is time to adapt the definition of chronic kidney disease according to age

Abstract Chronic kidney disease is a condition with high morbidity, mortality and healthcare costs which affects all population groups, having a significant impact on their quality of life. Its classification has been modified over time and there is still no universal consensus to differentiate a physiological change in kidney clearance from a pathological change. Below, we will discuss the importance of reconsidering the definition and classification in the general population according to age, including children and adults. (Acta Med Colomb 2021; 46.
