RESUMEN
Background and Objective@#Several studies have examined the predictors of mortality among COVID-19-infected patients; however, to date, few published studies focused on end-stage renal disease patients. The present study,therefore, aims to determine the predictors of in-hospital mortality among end-stage renal disease patients with COVID-19 admitted to a Philippine tertiary hospital. @*Methods@#The researcher utilized a retrospective cohort design. A total of 449 adult end-stage renal disease patients on renal replacement therapy diagnosed with moderate-to-severe COVID-19 and were admitted at the National Kidney and Transplant Institute from June 2020 to 2021 were included. Logistic regression analysis was used to determine the factors associated with in-hospital mortality. @*Results@#In-hospital mortality among end-stage renal disease patients with COVID-19 was 31.18% (95% CI: 26.92- 35.69%). Older age (OR=1.03), male sex (OR=0.56), diabetes mellitus (OR=1.80), coronary artery disease (OR=1.71), encephalopathy (OR=7.58), and intubation (OR=30.78) were associated with in-hospital mortality. @*Conclusion@#Patients with ESRD and COVID-19 showed a high in-hospital mortality rate. Older age, diabetes mellitus, coronary artery disease, encephalopathy, and intubation increased the odds of mortality. Meanwhile, males had lower odds of mortality than females.

Introduction@#Since the breakout of COVID-19 in December 2019, the virus has already affected and taken millions of lives over the past year. There is still much to learn about this disease. It has been postulated that the human kidney is a potential pathway for COVID-19 due to the presence of the ACE2 receptors found in the surfaces of kidney cells. Some studies that demonstrated acute tubular necrosis and lymphocyte infiltration among post mortem COVID-19 patients, concluding that the virus could directly damage the kidney, increasing the risk of the development of Acute Kidney Injury (AKI) among patients with COVID-19. This study investigated the incidence and severity of AKI among hospitalized COVID-19 patients and the association of the degree of AKI with regards to the severity and outcomes of COVID-19 patients.@*Methods@#This was a single-center cross-sectional study retrospective chart review of COVID-19 patients who developed AKI. Descriptive statistics were used to summarize the general and clinical characteristics of the patients. Frequency and proportion were used for categorical variables. Shapiro-Wilk test was used to determine the normality distribution of continuous variables. Continuous quantitative data that met the normality assumption was described using mean and standard deviation, while those that did not were described using median and range. Continuous variables which are normally distributed were compared using the One-way ANOVA, while those variables that are not normally distributed were compared using the Kruskal-Wallis H test. For categorical variables, the Chi-square test was used to compare the outcomes. If the expected percentages in the cells are less than 5%, Fisher's Exact Test was used instead.@*Results@#A total of 1441 COVID-19 in-patients from March 1, 2020 to March 1, 2021 were reviewed, 59 of whom were excluded. Among the adults with COVID-19 who developed AKI, 60% were in stage I, 10% in stage II, and 30% in stage III. The incidence of AKI among COVID-19 in-patients at Makati Medical Center was 13.10% (95% CI 11.36% - 14.99%). Among the 181 patients, 79 (43.65%, 95% CI 36.30 - 51.20) had died. The mortality rate is 22.02% for Stage I, 50% for Stage II, and 85.19% for Stage III. The median length of hospital stay was 12 days, ranging from 1 day up to 181 days. Full renal recovery on discharge was observed only in one-third of the patients. It was observed in 44.95% of those in Stage I, 27.78% of those in Stage II, and 5.56% of those in Stage III.@*Conclusion@#The study demonstrated that the incidence of AKI in hospitalized COVID-19 patients was 13.1% (95% CI 11.36% - 14.99%), which was lower than previously reported. This could be attributed to the longer study period wherein, to date, we have a better understanding of the disease and had already established a standard of care for treatment for the disease attributing to the decreased incidence of AKI among COVID-19 patients than what was initially reported. The development of AKI has a direct correlation with the degree of infection. Among patients who developed AKI, 20% required renal replacement therapy. Overall development of AKI increases the risk of mortality among hospitalized COVID-19 patients. The stage of AKI has a direct correlation with regards to mortality and has an indirect relationship with regards to renal recovery.

BACKGROUND@#Whether high cut-off (HCO) membranes are more effective than high-flux (HF) membranes in patients requiring renal replacement therapy (RRT) remains controversial. The aim of this systematic review was to investigate the efficacy of HCO membranes regarding the clearance of inflammation-related mediators, β2-microglobulin and urea; albumin loss; and all-cause mortality in patients requiring RRT.@*METHODS@#We searched all relevant studies on PubMed, Embase, Web of Science, the Cochrane Library, and China National Knowledge Infrastructure, with no language or publication year restrictions. Two reviewers independently selected studies and extracted data using a prespecified extraction instrument. Only randomized controlled trials (RCTs) were included. Summary estimates of standardized mean differences (SMDs) or weighted mean differences (WMDs) and risk ratios (RRs) were obtained by fixed-effects or random-effects models. Sensitivity analyses and subgroup analyses were performed to determine the source of heterogeneity.@*RESULTS@#Nineteen RCTs involving 710 participants were included in this systematic review. Compared with HF membranes, HCO membranes were more effective in reducing the plasma level of interleukin-6 (IL-6) (SMD -0.25, 95% confidence interval (CI) -0.48 to -0.01, P = 0.04, I2 = 63.8%); however, no difference was observed in the clearance of tumor necrosis factor-α (TNF-α) (SMD 0.03, 95% CI -0.27 to 0.33, P = 0.84, I2 = 4.3%), IL-10 (SMD 0.22, 95% CI -0.12 to 0.55, P = 0.21, I2 = 0.0%), or urea (WMD -0.27, 95% CI -2.77 to 2.23, P = 0.83, I2 = 19.6%). In addition, a more significant reduction ratio of β 2 -microglobulin (WMD 14.8, 95% CI 3.78 to 25.82, P = 0.01, I2 = 88.3%) and a more obvious loss of albumin (WMD -0.25, 95% CI -0.35 to -0.16, P < 0.01, I2 = 40.8%) could be observed with the treatment of HCO membranes. For all-cause mortality, there was no difference between the two groups (risk ratio [RR] 1.10, 95% CI 0.87 to 1.40, P = 0.43, I2 = 0.0%).@*CONCLUSIONS@#Compared with HF membranes, HCO membranes might have additional benefits on the clearance of IL-6 and β 2-microglobulin but not on TNF-α, IL-10, and urea. Albumin loss is more serious with the treatment of HCO membranes. There was no difference in all-cause mortality between HCO and HF membranes. Further larger high-quality RCTs are needed to strengthen the effects of HCO membranes.

Objective: To investigate the prognosis factors for death within 90 days after discharge in patients with acute kidney injury(AKI) treated requiring continuous renal replacement therapy(CRRT) undergoing surgery for acute Standford type A aortic dissection. Methods: The clinic data of 126 patients undergoing CRRT for postoperative AKI after acute type A aortic dissection surgery in the Center for Cardiac Intensive Care, Beijing Anzhen Hospital from July 2016 to February 2019 were analyzed retrospectively. There were 83 males and 43 females, aging (52.9±11.2) years(range: 25 to 70 years). The patients' demographic characteristics, disease-related information, perioperative data, laboratory indexes during CRRT, complications, and survival information within 90 days after discharge were recorded. Independent prognosis factors for death within 90 days of discharge were determined by Kaplan-Meier survival analysis, univariate and multifactorial Cox regression analysis. Results: Totally 57 of 126 patients(45.2%) died over the first 90 days after discharge. Kaplan-Meier survival analysis and univariate Cox regression analysis showed that there were significant differences between the non-survival and survival group including ≥65 years old, high lactate values 12 hours after CRRT, pulmonary infection, liver dysfunction, presence of permanent neurological complications, and postoperative ejection fraction(EF)<45%. Multifactorial Cox regression analysis revealed that ≥65 years old(HR=2.14, 95%CI: 1.09 to 4.21, P=0.03), high lactate values 12 hours after CRRT(HR=1.13, 95%CI: 1.06 to 1.20, P=0.01) and postoperative EF<45%(HR=2.21, 95%CI: 1.09 to 4.51, P=0.03) were independent prognosis factors for patients' death within 90 days after hospital discharge. Conclusions: ≥65 years old, high lactate values 12 hours after CRRT and postoperative EF<45% are independent prognosis factors for death within 90 days after discharge in patients undergoing CRRT for AKI after acute type A aortic dissection surgery. Proper identification and management of prognosis factors could be beneficial to improve patients' outcomes.

Introducción: la enfermedad renal crónica es una patología causada por la pérdida del funcionamiento del riñón con una filtración glomerular alterada por más de tres meses, por lo que es necesario recibir terapia de reemplazo renal consistente en la sustitución de esta función mediante la extracción de líquidos de la sangre y su filtración a través de membranas semipermeables, en especial para mantener la homeostasis mediante la eliminación de sustancias tóxicas nitrogenadas y desechos acumulados. Discusión y conclusiones: estos procedimientos y en particular la hemodiálisis puede presentar diversas complicaciones debido a que son procesos invasivos. Cabe mencionar que los pacientes en terapia de reemplazo presentan una disminución de la calidad de vida sobre todo a nivel físico y psicológico, a costa de mantener una mejor condición de su salud renal.
Introduction: chronic kidney disease is a condition caused by the loss of kidney function with impaired glomerular filtration for more than three months, making it necessary to receive renal replacement therapy which is a substitute for the normal function of kidneys by removing fluid from the blood using filtration across semipermeable membranes, especially to maintainhomeostasis by removing toxic nitrogenous substances and accumulated wastes. Discusion and conclusions: these procedures, in particular hemodialysis, may lead to various complications for they are invasive processes. It is worth mentioning that replacement therapy may decrease patients Ì quality of life, especially impacting their physical and psychological domains, at the expense of maintaining a better condition of their renal health.

Abstract Acute kidney injury (AKI) in hospitalized patients with COVID-19 is associated with higher mortality and a worse prognosis. Nevertheless, most patients with COVID-19 have mild symptoms, and about 5% can develop more severe symptoms and involve hypovolemia and multiple organ dysfunction syndrome. In a pathophysiological perspective, severe SARS-CoV-2 infection is characterized by numerous dependent pathways triggered by hypercytokinemia, especially IL-6 and TNF-alpha, leading to systemic inflammation, hypercoagulability, and multiple organ dysfunction. Systemic endotheliitis and direct viral tropism to proximal renal tubular cells and podocytes are important pathophysiological mechanisms leading to kidney injury in patients with more critical infection, with a clinical presentation ranging from proteinuria and/or glomerular hematuria to fulminant AKI requiring renal replacement therapies. Glomerulonephritis, rhabdomyolysis, and nephrotoxic drugs are also associated with kidney damage in patients with COVID-19. Thus, AKI and proteinuria are independent risk factors for mortality in patients with SARS-CoV-2 infection. We provide a comprehensive review of the literature emphasizing the impact of acute kidney involvement in the evolutive prognosis and mortality of patients with COVID-19.
Resumo A lesão renal aguda (LRA) em pacientes hospitalizados com COVID-19 está associada a maior mortalidade e um pior prognóstico. No entanto, a maioria dos pacientes com COVID-19 tem sintomas leves e cerca de 5% podem desenvolver sintomas mais graves e envolver hipovolemia e síndrome de disfunção de múltiplos órgãos. Em uma perspectiva fisiopatológica, a infecção grave por SARS-CoV-2 é caracterizada por numerosas vias dependentes desencadeadas por hipercitocinemia, especialmente IL-6 e TNF-alfa, levando à inflamação sistêmica, hipercoagulabilidade e disfunção de múltiplos órgãos. A endotelite sistêmica e o tropismo viral direto às células tubulares proximais renais e podócitos são mecanismos fisiopatológicos importantes que levam à lesão renal em pacientes com infecção mais crítica, com uma apresentação clínica que varia de proteinúria e/ou hematúria glomerular a LRA fulminante, exigindo terapias renais substitutivas. Glomerulonefrite, rabdomiólise e drogas nefrotóxicas também estão associadas a danos renais em pacientes com COVID-19. Assim, a LRA e a proteinúria são fatores de risco independentes para mortalidade em pacientes com infecção por SARS-CoV-2. Fornecemos uma revisão abrangente da literatura, enfatizando o impacto do envolvimento renal agudo no prognóstico evolutivo e na mortalidade de pacientes com COVID-19.

RESUMEN La insuficiencia renal aguda es definida como la pérdida de función del riñón ocasionada por diversas causas, entre ellas infección e ingesta de fármacos. Esta entidad tiene alta morbilidad y mortalidad en las unidades de cuidados críticos. El tratamiento de la misma va desde la propia protección renal hasta la sustitución artificial de las funciones del riñón lesionado. En la actualidad la terapia de reemplazo renal continua se ha utilizado como soporte renal, y ofrece mayor estabilidad clínica a los pacientes más inestables. En esta revisión se comentan conceptos, indicaciones y los más recientes estudios que validan el uso de esta terapéutica, así como el método de programación que se utilizó en un paciente con diagnóstico de una leptospirosis icterohemorrágica (síndrome de Weil), que estuvo en shock séptico con disfunción multiorgánica, donde se empleó esta terapia con resultados satisfactorios (AU).
ABSTRACT Acute kidney failure is defined as the loss of kidney function caused by various causes, including infection and drug intake. This entity has high morbidity and mortality in critical care units. Treatment ranges from renal protection to artificial replacement of the functions of the injured kidney. Currently, continuous renal replacement therapy has been used as renal support, and offers greater clinical stability to the most unstable patients. In this review, authors discuss concepts, indications and the most recent studies that validate the use of this therapeutic, as well as the programming method that was used in a patient with diagnosis of icteric-hemorrhagic leptospirosis (Weil syndrome), who was in septic shock with multiorgan dysfunction, where this therapy was used with satisfactory results (AU).

Resumo A partir da liberalização do capital estrangeiro na Saúde, engendrou-se uma nova tendência no processo de acumulação de capital no complexo econômico industrial da saúde, sobretudo nos níveis de atenção terciários e serviços de Atendimento, Tratamento e Diagnóstico (SADT). Com o intuito de compreender essa dinâmica, o presente artigo procurou analisar o processo de aquisições de clínicas de Terapia Renal Substitutiva (TRS) pelas empresas de capital internacional no Brasil. Para tanto, foi desenvolvido um percurso metodológico em duas etapas: a primeira consistiu na análise quantitativa-descritiva, de modalidade econômica, da totalidade das empresas de capital internacional que atuam na produção de insumos e tecnologias e nos serviços de assistência em TRS; a segunda foi desenvolvida em uma análise qualitativa de entrevistas semi-estruturadas de atores-chaves provenientes dos setores privado e público e sociedade civil organizada. Portanto, o processo de avanço do capital internacional traz consigo uma alteração qualitativa da organização, assistência e financiamento da TRS. Podemos encontrar, especialmente nos casos dos serviços públicos e privados complementares, uma tendência de restrição à atenção integral e um entrave ao direito universal à saúde.
Abstract Since the liberalization of foreign capital in health a new trend has arisen in the process of capital accumulation in the industrial economic complex of health, especially at the levels of outsourced care and Services of Care, Treatment and Diagnosis (SCTD). In order to contribute to the understanding of this dynamic, this article sought to analyze the acquisition process of Renal Replacement Therapy (RRT) clinics by international capital companies in Brazil. To achieve this, a two-stage methodological path was developed; the first consisted in the quantitative-descriptive analysis of the economic type of all the international capital companies that operate in the production of input and technologies and in RRT care services; the second was developed by a qualitative analysis of semi-structured interviews of key actors from the private and public sectors and organized civil society. Therefore, the process of the advance of international capital brings with it a qualitative change in the organization, assistance and financing of RRT. It can be seen that, especially in the cases of complementary public and private services, there is a tendency to restrict care and create an obstacle to the universal right to health.

Abstract Introduction: Atypical hemolytic uremic syndrome (aHUS) is a rare disorder characterized by the triad of microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury, which primarily affects preschool-aged children. This study's aim was to describe the clinical profile, management, and long-term outcome of the genetic aHUS patients admitted to a tertiary care pediatric nephrology center during 20 years. Methods: We performed a retrospective analysis of the clinical records of all aHUS patients younger than 18 years with identified genetic mutations. Data on clinical features, genetic study, therapeutic interventions, and long-term outcomes were reviewed. Results: Five cases of aHUS with an identified genetic mutation were included; all were inaugural cases with the youngest being 4 months old. Complement factor H gene mutation was identified in four patients. Therapeutic plasma exchange was performed for acute management in 4 patients, one of whom also needed acute renal replacement therapy (peritoneal dialysis). All patients went on complete remission, 2 had more than one relapse but only 1 of these progressed to chronic kidney disease during the follow-up period (median (25th-75th percentile), 136 (43.5-200.5) months). Conclusion: In children, the prognosis of renal function seems to be strongly dependent on the genetic background, thus being crucial to perform genetic study in all aHUS cases. In our cohort, 2 patients presented genetic mutations not previously described. Recent innovations on the genetic field leading to the identification of new mutations has lead to a better understanding of aHUS pathogenesis, but further studies, focusing on the genotype-phenotype correlation, with longer follow-up periods, are needed.
Resumo Introdução: A síndrome hemolítica urêmica atípica (SHUa) é um distúrbio raro caracterizado pela tríade de anemia hemolítica microangiopática, trombocitopenia e lesão renal aguda, afetando principalmente crianças em idade pré-escolar. O objetivo deste estudo foi descrever perfil clínico, manejo e desfecho em longo prazo dos pacientes com SHUa genética admitidos em um centro terciário de nefrologia pediátrica durante 20 anos. Métodos: Realizamos análise retrospectiva dos registros clínicos de todos os pacientes com SHUa menores de 18 anos com mutações genéticas identificadas. Revisaram-se dados sobre características clínicas, estudo genético, intervenções terapêuticas e desfechos em longo prazo. Resultados: Incluíram-se cinco casos de SHUa com uma mutação genética identificada; sendo todos casos inaugurais, o mais jovem tendo 4 meses de idade. A mutação no gene do fator H do complemento foi identificada em quatro pacientes. Plasmaférese terapêutica foi realizada para tratamento agudo em 4 pacientes, um dos quais também necessitou terapia renal substitutiva aguda (diálise peritoneal). Todos os pacientes tiveram remissão completa, 2 mais de uma recidiva, mas apenas 1 evoluiu para doença renal crônica durante acompanhamento (mediana (percentil 25°-75°), 136 (43,5-200,5) meses). Conclusão: Em crianças, o prognóstico da função renal parece ser fortemente dependente do histórico genético, sendo crucial realizar estudo genético em todos os casos de SHUa. Em nossa coorte, 2 pacientes apresentaram mutações genéticas não descritas anteriormente. Inovações recentes no campo genético que levaram à identificação de novas mutações conduziram a um melhor entendimento da patogênese SHUa, mas são necessários mais estudos, focando na correlação genótipo-fenótipo, com períodos de acompanhamento mais longos.

Objetivo: Comparar a qualidade de vida dos pacientes submetidos à hemodiálise, que residiam na cidade onde realizavam o tratamento com aqueles que residiam em outros municípios do estado de Sergipe. Método: trata-se de um estudo transversal, descritivo e comparativo, realizado em uma clínica de diálise em Sergipe. A amostra foi composta por 170 pacientes adultos, em tratamento hemodialítico com condições cognitivas para responder ao formulário. O desfecho qualidade de vida foi mensurado por meio da versão brasileira do Kidney Disease and Quality-Of-Life Short-Form (KDQOL-SF). Dados sociodemográficos e de acesso ao serviço foram consideradas variáveis dependentes para comparação entre os grupos. Resultados: Independente da procedência e características sociodemográficas dos participantes, baixos escores de qualidade de vida foram encontrados em todos os componentes da avaliação, especialmente médias inferiores a 50. Por outro lado, percebeu-se que os pacientes provenientes do interior apresentaram maiores escores de qualidade de vida. Conclusão: pacientes do sexo masculino, com idade média de 40 anos, com maior escolaridade e procedentes do interior apresentaram melhores escores para qualidade de vida. (AU)

Resumen El síndrome de DRESS (Reacción a drogas con eosinofilia y síntomas sistémicos) es una patología poco frecuente en Pediatría, descrita por primera vez en 1996, por Bocquet. Puede presentarse en un tiempo variable luego de exposición a algunos medicamentos, se caracteriza por fiebre, compromiso cutáneo y de órganos internos. En este caso, se presenta a un paciente de 13 años, con antecedente de uso de Trimetroprim sulfa desde hace 2 meses, con cuadro de 3 días consistente en fiebre y rash cutáneo, sin compromiso de mucosas, con respuesta no favorable al manejo con esteroide, requiriendo Inmunoglobulina IV. Semanas después del inicio de los síntomas y evolución estable presenta insuficiencia renal aguda que requirió terapia de reemplazo renal. Se descartaron otras patologías subyacentes de índole autoinmune. Hubo recuperación de azoados y normalización de los demás paraclínicos el día 40 de la enfermedad. El paciente continúa asintomático, 4 meses después, con tratamiento con esteroide oral, en descenso lento y gradual. Se debe considerar la evaluación permanente de las pruebas de función renal en los pacientes que presenten Síndrome de DRESS, por su asociación con Nefritis intersticial aguda y complicaciones relacionadas.
Abstract DRESS syndrome (Drug Reaction with Eosinophilia and Systemic Symptoms) is a rare pathology in Pediatrics, first described in 1996 by Bocquet. It can appear in a variable period of time after exposure to some medications, it is characterized by fever, skin involvement and internal organs. A 13-year-old patient is presented, with a history of use of Trimethoprim sulfa for two months, with a disease of three days of evolution, consisting of fever and skin rash, without mucosal involvement, with an unfavorable response to steroid management, requiring Intravenous inmunoglobulin. Weeks after the onset of symptoms and stable evolution, he presented acute renal failure that required renal replacement therapy. Other underlying autoimmune pathologies were ruled out. There was recovery of renal function test and normalization of the other paraclinical on day 40 of the disease. Patient remains asymptomatic four months later, with oral steroid treatment, in slow and gradual decline. Permanent evaluation of renal function tests should be considered in patients with DRESS syndrome, due to its association with acute tubulointerstitial nephritis and related complications.

Abstract Introduction Although the use of matching techniques in observational studies has been increasing, it is not always adequate. Clinical trials are not always feasible in critically ill patients with renal outcomes, and observational studies are an important alternative. Objective Through a scoping review, determine the available evidence on the use of matching methods in studies involving critically ill patients and renal outcome assessments. Methods Medline, Embase, and Cochrane databases were used to identify articles published between 1992 and week 10 of 2020. Studies had to assess different exposures in critically ill patients with renal outcomes using propensity score matching. Results Most publications are cohort studies 94 (94.9%), with five (5.1%) reporting cross-sectional studies. The main pharmacological intervention was the use of antibiotics in seven studies (7.1%) and the main risk factor studied was renal injury prior to ICU admission in 10 studies (10.1%). The use of standardized means to assess balance of baseline characteristics was found in only 28 studies (28.2%). Most studies 95 (96%) used logistic regression to calculate the propensity score. Conclusion Major inconsistencies were observed regarding the use of methods and reporting of findings. Considerations related to the use of propensity score matching methods and reporting of findings are summarized.
Resumen Introducción El uso de técnicas de emparejamiento en estudios observacionales ha ido en aumento y no siempre se usa adecuadamente. Los experimentos clínicos no siempre son factibles en los pacientes críticos con desenlaces renales, por lo que los estudios observacionales son una alternativa importante. Objetivo Mediante una revisión de alcance, determinar la evidencia disponible sobre la utilización de los métodos de emparejamiento en los estudios que incluyen pacientes críticamente enfermos y que evalúan desenlaces renales. Métodos Se utilizaron las bases de datos de Medline, Embase, y Cochrane para identificar artículos publicados entre 1992 y 2020 hasta la semana 10, que estudiaran diferentes exposiciones en el paciente crítico con desenlaces renales y utilizaran métodos de emparejamiento por propensión. Resultados La mayoría de las publicaciones (94) son estudios de Cohorte (94,9 %), cinco estudios (5,1 %) correspondieron a cross-secctional. La principal intervención farmacológica fue el uso de antibióticos en siete estudios (7,1 %) y el principal factor de riesgo estudiado fue la lesión renal previa al ingreso a UCI en diez estudios (10,1 %). El balance entre las características de base evaluado mediante medias estandarizadas se encontró solo en 28 estudios (28,2 %). La mayoría de los estudios 95 (96 %) utilizaron regresión logística para calcular el índice de propensión. Conclusiones Se observaron grandes inconsistencias en la utilización de los métodos y en el informe de los hallazgos. Se hace un resumen de los aspectos por considerar en la utilización de los métodos y reporte de los hallazgos con el emparejamiento por índice de propensión.

SARS-CoV-2 infection has a wide spectrum of clinical manifestations secondary to the impairment of different organs, including kidney. Rhabdomyolysis is produced by disintegration of striated muscle and the liberation of its contents to the extracellular fluid and bloodstream. This may produce hydro electrolytic disorders and acute kidney injury. We report a 35-year-old female with a history of SARS-CoV-2 infection who was hospitalized because of respiratory failure and developed renal failure. The etiologic study showed elevated total creatine kinase levels and a magnetic resonance imaging confirmed rhabdomyolysis. The patient required supportive treatment with vasoactive drugs, mechanic ventilation and kidney replacement therapy. She had a favorable evolution with resolution of respiratory failure and improvement of kidney function.

Abstract This patient was a 73-year-old man who initially came to our service with acute respiratory failure secondary to COVID-19. Soon after hospitalization, he was submitted to orotracheal intubation and placed in the prone position to improve hypoxia, due to severe acute respiratory syndrome (SARS). On the third day of hospitalization, he developed acute oliguric kidney injury and volume overload. The nephrology service was activated to obtain deep venous access for renal replacement therapy (RRT). The patient could not be placed in the supine position due to significant hypoxemia. A 50-cm Permcath (MAHURKARTM, Covidien, Massachusetts, USA) was inserted through the left popliteal vein. This case report describes a possible challenging scenario that the interventional nephrologist may encounter when dealing with patients with COVID-19 with respiratory impairment in the prone position.
Resumo O paciente era um homem de 73 anos de idade que inicialmente veio ao nosso serviço com insuficiência respiratória aguda secundária à COVID-19. Logo após a internação, ele foi submetido à intubação orotraqueal e pronado para melhorar a hipóxia devido à síndrome respiratória aguda grave (SARS - do inglês "severe acute respiratory syndrome"). No terceiro dia de internação, o mesmo desenvolveu lesão renal aguda oligúrica e sobrecarga de volume. O serviço de nefrologia foi acionado para realizar acesso venoso profundo para terapia renal substitutiva (TRS). O paciente não pôde ser colocado na posição de decúbito dorsal devido a uma hipoxemia significativa. Um Permcath de 50 cm (MAHURKARTM, Covidien, Massachusetts, EUA) foi inserido através da veia poplítea esquerda. Este relato de caso descreve um possível cenário desafiador com o qual o nefrologista intervencionista pode se deparar ao lidar com pacientes com COVID-19 com problemas respiratórios e colocados em pronação.

RESUMO Objetivo: Avaliar a incidência de hipotermia em pacientes em terapia renal substitutiva contínua na unidade de terapia intensiva. Como objetivos secundários, determinar fatores associados e comparar a ocorrência de hipotermia entre duas modalidades de terapia renal substitutiva contínua. Métodos: Estudo de coorte, prospectivo, realizado com pacientes adultos internados em uma unidade de terapia intensiva clínico-cirúrgica, que realizaram terapia renal substitutiva contínua em um hospital universitário público de alta complexidade do Sul do Brasil, de abril de 2017 a julho de 2018. A hipotermia foi definida como queda da temperatura corporal ≤ 35ºC. Os pacientes incluídos no estudo foram acompanhados nas 48 horas iniciais de terapia renal substitutiva contínua. Os dados foram coletados pelos pesquisadores por meio da consulta aos prontuários e às fichas de registro das terapias renais substitutivas contínuas. Resultados: Foram avaliados 186 pacientes distribuídos igualmente entre dois tipos de terapia renal substitutiva contínua: hemodiálise e hemodiafiltração. A incidência de hipotermia foi de 52,7%, sendo maior nos pacientes que internaram por choque (risco relativo de 2,11; IC95% 1,21 - 3,69; p = 0,009) e nos que fizeram hemodiafiltração com aquecimento por mangueira na linha de retorno (risco relativo de 1,50; IC95% 1,13 - 1,99; p = 0,005). Conclusão: A hipotermia em pacientes críticos com terapia renal substitutiva contínua é frequente, e a equipe intensivista deve estar atenta, em especial quando há fatores de risco associados.
ABSTRACT Objective: To evaluate the incidence of hypothermia in patients undergoing continuous renal replacement therapy in the intensive care unit. As secondary objectives, we determined associated factors and compared the occurrence of hypothermia between two modalities of continuous renal replacement therapy. Methods: A prospective cohort study was conducted with adult patients who were admitted to a clinical-surgical intensive care unit and underwent continuous renal replacement therapy in a high-complexity public university hospital in southern Brazil from April 2017 to July 2018. Hypothermia was defined as a body temperature ≤ 35ºC. The patients included in the study were followed for the first 48 hours of continuous renal replacement therapy. The researchers collected data from medical records and continuous renal replacement therapy records. Results: A total of 186 patients were equally distributed between two types of continuous renal replacement therapy: hemodialysis and hemodiafiltration. The incidence of hypothermia was 52.7% and was higher in patients admitted for shock (relative risk of 2.11; 95%CI 1.21 - 3.69; p = 0.009) and in those who underwent hemodiafiltration with heating in the return line (relative risk of 1.50; 95%CI 1.13 - 1.99; p = 0.005). Conclusion: Hypothermia in critically ill patients with continuous renal replacement therapy is frequent, and the intensive care team should be attentive, especially when there are associated risk factors.

BACKGROUND@#Chronic kidney disease (CKD) is an independent risk factor for progression to an end-stage renal disease requiring dialysis or kidney transplantation. We investigated the association of lifestyle behaviors with the initiation of renal replacement therapy (RRT) among CKD patients using an employment-based health insurance claims database linked with specific health checkup (SHC) data.@*METHODS@#This retrospective cohort study included 149,620 CKD patients aged 40-74 years who underwent a SHC between April 2008 and March 2016. CKD patients were identified using ICD-10 diagnostic codes and SHC results. We investigated lifestyle behaviors recorded at SHC. Initiation of RRT was defined by medical procedure claims. Lifestyle behaviors related to the initiation of RRT were identified using a Cox proportional hazards regression model with recency-weighted cumulative exposure as a time-dependent covariate.@*RESULTS@#During 384,042 patient-years of follow-up by the end of March 2016, 295 dialysis and no kidney transplantation cases were identified. Current smoking (hazard ratio: 1.87, 95% confidence interval, 1.04─3.36), skipping breakfast (4.80, 1.98─11.62), and taking sufficient rest along with sleep (2.09, 1.14─3.85) were associated with the initiation of RRT.@*CONCLUSIONS@#Among CKD patients, the lifestyle behaviors of smoking, skipping breakfast, and sufficient rest along with sleep were independently associated with the initiation of RRT. Our study strengthens the importance of monitoring lifestyle behaviors to delay the progression of mild CKD to RRT in the Japanese working generation. A substantial portion of subjects had missing data for eGFR and drinking frequency, warranting verification of these results in prospective studies.

BACKGROUND@#Acute kidney injury (AKI) is a common and serious complication following lung transplantation (LTx), and it is associated with high mortality and morbidity. This study assessed the incidence of AKI after LTx and analyzed the associated perioperative factors and clinical outcomes.@*METHODS@#This retrospective study included all adult LTx recipients at the China-Japan Friendship Hospital in Beijing between March 2017 and December 2019. The outcomes were AKI incidence, risk factors, mortality, and kidney recovery. Multivariate analysis was performed to identify independent risk factors. Survival analysis was presented using the Kaplan-Meier curves.@*RESULTS@#AKI occurred in 137 of the 191 patients (71.7%), with transient AKI in 43 (22.5%) and persistent AKI in 94 (49.2%). AKI stage 1 occurred in 27/191 (14.1%), stage 2 in 46/191 (24.1%), and stage 3 in 64/191 (33.5%) of the AKI patients. Renal replacement therapy (RRT) was administered to 35/191 (18.3%) of the patients. Male sex, older age, mechanical ventilation (MV), severe hypotension, septic shock, multiple organ dysfunction (MODS), prolonged extracorporeal membrane oxygenation (ECMO), reintubation, and nephrotoxic agents were associated with AKI (P < 0.050). Persistent AKI was independently associated with pre-operative pulmonary hypertension, severe hypotension, post-operative MODS, and nephrotoxic agents. Severe hypotension, septic shock, MODS, reintubation, prolonged MV, and ECMO during or after LTx were related to severe AKI (stage 3) (P < 0.050). Patients with persistent and severe AKI had a significantly longer duration of MV, longer duration in the intensive care unit (ICU), worse downstream kidney function, and reduced survival (P < 0.050).@*CONCLUSIONS@#AKI is common after LTx, but the pathogenic mechanism of AKI is complicated, and prerenal causes are important. Persistent and severe AKI were associated with poor short- and long-term kidney function and reduced survival in LTx patients.
