ABSTRACT

Introducción: La morbimortalidad por enfermedad renal crónica (ERC) ha presentado en las dos últimas décadas un incremento desconcertante. En Cuba, aunque la mortalidad por esta causa ha tenido un comportamiento estable, la incidencia y la prevalencia se mantienen elevadas. Objetivo: Caracterizar los pacientes fallecidos con ERC según variables demográficas, causas de muerte y otras variables seleccionadas. Material y Métodos: Estudio descriptivo, transversal. El universo de estudio estuvo constituido por todos los fallecidos del país en el período, en cuyos certificados de defunción se incluyó entre una de las causas, la ERC. La información fue obtenida de las bases de datos de mortalidad de la Dirección Nacional de Registros Médicos y Estadísticos de Salud del MINSAP. Procesamiento de forma automatizada (SPSS versión 22.0). Fueron calculadas las frecuencias absolutas y relativas. Resultados: La frecuencia global de pacientes fallecidos se incrementó de forma mantenida y resultó mayor en la provincia La Habana (23,6 por ciento). La media de la edad fue de 70 años. Prevaleció el sexo masculino, el color de piel blanco y el grupo de edad de 80 años y más. Los porcentajes más altos según la causa básica de muerte correspondieron a enfermedad renal hipertensiva y Diabetes Mellitus. Conclusiones: Los fallecidos con ERC son mayormente hombres, de piel blanca, y con edades avanzadas. Las principales causas de muerte son la enfermedad hipertensiva y la Diabetes Mellitus(AU)


Introduction: Chronic kidney disease (CKD) has increased at an alarming rate worldwide over the last two decades. Although mortality due to CKD has registered stable behavior in Cuba, its prevalence and incidence are showing higher rates. Objective: To describe the main demographic features of deceased patients with CKD in Cuba, the causes of death and other variables during the period 2011-2016. Material and Methods: A descriptive cross-sectional study was conducted. The study universe included all deceased patients in Cuba during the period mentioned. CKD was listed on their death certificates as one of the causes of death. The information used was obtained from the mortality database available on the National Directorate of Medical Records and Health Statistics of the Cuban Ministry of Public Health. Data was processed using SPSS version 22.0. Absolute and relative frequencies were calculated. Results: The global frequency of deceased patients showed a steady increase. Havana was the city that presented the highest percentage (23,6 percent). Nonetheless, the rest of the cities showed an increased frequency rate. The median age was 70 years. The male gender prevailed over the female one as well as white ethnicity and the 80 years and over age group. Regarding the cause of death, the highest percentages corresponded to hypertensive kidney disease and Diabetes Mellitus. Conclusions: Most of the deceased patients with CKD are male, white and at advanced ages. The main causes of death are hypertensive disease and Diabetes Mellitus(AU)

ABSTRACT

Introducción: La enfermedad renal crónica constituye un gran problema de salud en el mundo y en Cuba. Para el año 2040 puede convertirse en la quinta causa más común de años de vida potencialmente perdidos a nivel mundial y es una importante causa de gastos para la salud, la economía y el seguro social de los países. Objetivo: Caracterizar la mortalidad en pacientes renales crónicos en edad laboral en Cuba, en los años 2011-2017, según variables sociodemográficas seleccionadas. Métodos: Investigación transversal descriptiva. El universo estuvo constituido por los 5 716 fallecidos con enfermedad renal crónica. La información fue tomada de las bases de datos de mortalidad de la Dirección Nacional de Estadísticas, del Ministerio de Salud Pública. Se estudiaron las variables: edad, sexo, ocupación y principales causas de muerte. Se calcularon tasas brutas, así como tasas de mortalidad específicas. Resultados: En la edad laboral la mortalidad por enfermedad renal crónica presentó oscilaciones del año 2011 al 2017. La edad media al morir fue 53.7 años, los mayores de 61 años, hombres, presentaron el mayor riesgo (16 por 10 000 habitantes). La tasa en la población económicamente activa desocupada fue de 33 por 10 000 habitantes. El riesgo fue mayor en las ocupaciones elementales (9 por 10 000 habitantes). La enfermedad renal hipertensiva fue la principal causa de muerte (17 por 100 000 habitantes). Conclusiones: Existe ligero incremento de la mortalidad, en hombres el riesgo es mayor, la tasa más alta es en población económicamente activa desocupada y en las ocupaciones elementales. La principal causa de muerte es la enfermedad renal hipertensiva(AU)


Introduction: Chronic kidney disease constitutes a major health problem in Cuba and worldwide. By 2040 it may become the fifth most common cause of years of life potentially lost, worldwide, and a major cause of health expenses, economy and social security. Objective: To describe mortality in chronic kidney patients of working ages in Cuba, from 2011to 2017, according to selected sociodemographic variables. Methods: This is descriptive cross-sectional research. The universe consisted of 5,716 deceased subjects with chronic kidney disease. The information was taken from the mortality databases of the National Directorate of Statistics, from the Ministry of Public Health. The variables were studied age, sex, occupation and main causes of death. Gross and specific mortality rates were calculated. Results: In working age, mortality from chronic kidney disease fluctuated from 2011 to 2017. The mean age at death was 53.7 years, those over 61 years of age, men, had the highest risk (16 per 10,000 inhabitants). The rate in the economically active unemployed population was 33 per 10,000 inhabitants. The risk was higher in basic occupations (9 per 10,000 inhabitants). Hypertensive kidney disease was the leading cause of death (17 per 100,000 population). Conclusions: There is a slight increase in mortality, the risk is higher in men, the highest rate is in the economically active unemployed population and in basic occupations. The leading cause of death is hypertensive kidney disease(AU)

ABSTRACT

Abstract Background Cardiovascular disease (CVD) is commonly associated with chronic kidney disease (CKD). These diseases have a significant impact on life expectancy. Individuals with CKD are more likely to die from CVD than to progress to end-stage kidney disease. Objective To assess cardiovascular risk factors of patients with CKD under conservative treatment. Methods This was an observational, cross-sectional study. Socioeconomic, anthropometric, biochemical, and physical inactivity data were assessed, and 10-year risk for CVD were estimated using the Framingham Score in patients with CKD under conservative treatment. For statistical analysis, the Student's t-test and Pearson's chi-square test were performed. Results A total of 172 individuals were evaluated, 57% of whom were male, with an average age of 68.85 ± 11.41 years. The prevalence of hypertension and diabetes were 87.2% and 53.5%, respectively; 62.2% were physically inactive; 9.9% of men were smokers and 12.8% consumed alcohol. According to BMI, 82.4% of adults <60 years old and 60.6% of those older than 60 years were overweight. High waist circumference and a high waist-hip ratio were highly prevalent in females (91.9% and 83.8%, respectively) and males (64.3% and 39.8%, respectively); 92.4% had a high body fat percentage and 73.3% high uric acid levels. According to the Framingham score, 57% have a medium or high risk of developing CVD in 10 years. Conclusion There was a high prevalence of cardiovascular risk factors in the population studied. The assessment of cardiovascular risk factors in patients with CKD makes it possible to guide the conduct of health professionals to prevent mortality from cardiovascular causes.

ABSTRACT

La enfermedad renal crónica (ERC) es una patología que se asocia a la diabetes y enfermedades cardiovasculares principalmente. Es la destrucción progresiva de unidades funcionales del riñón, hasta perder capacidad de filtrar sustancias tóxicas. Con el objetivo de contar con información y conocimientos epidemiológicos oportunos, que permitan contribuir a una adecuada orientación de acciones en salud pública, se llevó a cabo un análisis descriptivo de las bases de datos de morbilidad del Sistema Gerencial de Salud (Sigsa), Unidad Nacional de Atención al Enfermo Renal Crónico (Unaerc), y de mortalidad del Instituto Nacional de Estadística (INE), Códigos CIE10:N18-19. A partir de 2013 se agregaron casos de Unaerc a Sigsa; esto incrementó seis veces el número (601/4,099) entre 2012-2013; de igual forma se incrementó entre 2013/2018, 87 % (4,099/7,760) y entre 2008/2017 se incrementó 15 veces más. En 2018 el mayor número de casos se reportó en Guatemala, Santa Rosa, Petén y Escuintla. Las tasas de prevalencia más altas, fueron en Santa Rosa, Jutiapa, Petén, Guatemala, Escuintla y Quetzaltenango. El grupo de edad con mayor número de casos fue de 25 a 59 años. Entre 2008 y 2017, se documentaron 19,491 casos en estadio V. Durante los últimos 10 años, ha incrementado 56 % la mediana de fallecidos, siendo 2,085 casos anuales. La mortalidad fue mayor en los departamentos con clima cálido, con ocupaciones elementales y sin ninguna escolaridad. Es importante fortalecer el diagnóstico para la detección de estadios tempranos, además asegurar el tratamiento de diabetes mellitus y enfermedades cardiovasculares.


Chronic kidney disease (CKD) is a pathology mainly associated with diabetes and cardiovascular diseases. It is the progressive destruction of functional units of the kidney, until losing the ability to filter toxic substances. In order to have timely epidemiological information and knowledge, timely to contribute with an adequate orientation of actions in public health, a descriptive analysis was carried out of databases of Managerial Health System (Sigsa), National Unit for Chronic Kidney Disease Attention (Unaerc) for morbidity, and the National Institute for Statistics (INE) for mortality, ICD10 codes: N181. As of 2013, Unaerc cases were added to Sigsa; this increased the number (601/4,099) six times between 2012-2013. Similarly, it increased between 2013-2018, 87 % (4,099/7,760) and between 2008/2017 it increased 15 times more. In 2018 the highest number of cases was reported in Guatemala, Santa Rosa, Peten and Escuintla. The highest prevalence rates were in the departments of Santa Rosa, Jutiapa, Peten, Guatemala, Escuintla and Quetzaltenango. The age group with the highest number of cases was 25 to 59 years. Between 2008 and 2017, 19,491 cases were documented on stage V. During the last 10 years, the median number of deaths has increased by 5,685 per year. Mortality was higher in the departments with warm weather, with elementary occupations and without any schooling. It is important to strengthen the diagnosis for the detection of early stages, in order to allow safe treatment for diabetes mellitus and cardiovascular diseases.

ABSTRACT

ABSTRACT BACKGROUND: Findings regarding the effects of hyperuricemia on renal function and mortality have been inconsistent. OBJECTIVES: To investigate the effects of hyperuricemia on incident renal replacement therapy and all-cause mortality among patients with chronic kidney disease (CKD). DESIGN AND SETTING: Retrospective cohort study conducted in a medical center in Taiwan. METHODS: Patients with CKD in stages 3-5, without histories of renal replacement therapy, were consecutively recruited from 2007 to 2013. Their medical history, laboratory and medication data were collected from hospital records. The mean uric acid level in the first year of follow-up was used for analyses. Hyperuricemia was defined as mean uric acid level ≥ 7.0 mg/dl in men or ≥ 6.0 mg/dl in women. The primary outcomes were incident renal replacement therapy and all-cause mortality, and these data were retrospectively collected from hospital records until the end of 2015. RESULTS: A total of 4,381 patients were analyzed (mean age 71.0 ± 14.8 years; males 62.7%), and the median follow-up period was 2.5 years. Patients with hyperuricemia were at increased risk of incident renal replacement therapy and all-cause mortality, especially those with CKD in stages 4 or 5. Compared with patients with CKD in stage 3 and normouricemia, patients with CKD in stages 4 or 5 presented significantly higher risk of all-cause mortality only if they had hyperuricemia. CONCLUSIONS: In patients with CKD in stages 3-5, hyperuricemia was associated with higher risk of incident renal replacement therapy and all-cause mortality. Whether treatment with uric acid-lowering drugs in these patients would improve their outcomes merits further investigation.

ABSTRACT

Abstract Objective: To evaluate the association between dysnatremias or dyschloremias and mortality during hospitalization in patients with acute kidney injury (AKI) or chronic kidney disease (CKD) undergoing acute hemodialysis. Methods: We carried out a retrospective cohort study on adult patients undergoing acute hemodialysis with AKI or CKD diagnosis at a public hospital in Lima, Peru. Dysnatremias were categorized as hyponatremia (Na < 135mmol/L) or hypernatremia (Na > 145mmol/L), and dyschloremias were defined as hypochloremia (Cl < 98 mmol/L) or hyperchloremia (Cl > 109mmol/L). The outcome of interest was mortality during hospitalization. We performed generalized lineal Poisson family models with bias-corrected and accelerated non-parametric bootstrap to estimate the risk ratios at crude (RR) and adjusted analysis (aRR) by gender, age, HCO3 (for all patients) and Liaño score (only for AKI) with CI95%. Results: We included 263 patients (mean age: 54.3 years, females: 43%): 191 with CKD and 72 with AKI. Mortality was higher in patients with AKI (59.7%) than in patients with CKD (14.1%). In overall, patients with hypernatremia had a higher mortality during hospitalization compared to those who had normal sodium values (aRR: 1.82, 95% CI: 1.17-2.83); patients with hyponatremia did not have different mortality (aRR: 0.19, 95% CI: 0.69-2.04). We also found that hyperchloremia (aRR: 1.35, 95% CI: 0.83-2.18) or hypochloremia (aRR: 0.66, 95% CI: 0.30-14.78) did not increase mortality in comparison to normal chloride values. No association between dysnatremias or dyschloremias and mortality during hospitalization was found in CKD and AKI subgroups. Conclusions: In our exploratory analysis, only hypernatremia was associated with mortality during hospitalization among patients with AKI or CKD undergoing acute hemodialysis.


Resumo Objetivo: Avaliar a associação entre distúrbios do sódio ou do cloro e mortalidade hospitalar de pacientes com insuficiência renal aguda (IRA) ou doença renal crônica (DRC) submetidos a hemodiálise aguda. Métodos: O presente estudo de coorte retrospectiva incluiu pacientes adultos submetidos a hemodiálise aguda com diagnóstico de IRA ou DRC em um hospital público de Lima, Peru. Os distúrbios do sódio foram classificados como hiponatremia (Na < 135mmol/L) ou hipernatremia (Na > 145mmol/L), enquanto os distúrbios do cloro foram classificados como hipocloremia (Cl < 98 mmol/L) ou hipercloremia (Cl > 109mmol/L). O desfecho de interesse foi mortalidade hospitalar. Utilizamos modelos de Poisson da família de modelos lineares generalizados com bootstrap não-paramétrico e correção de viés acelerado para estimar os riscos relativos na análise bruta (RR) e ajustada (RRa) para sexo, idade, HCO3 (para todos os pacientes) e escore de Liaño (apenas para IRA) com IC 95%. Resultados: Foram incluídos 263 pacientes (idade média 54,3 anos; 43% do sexo feminino), 191 com DRC e 72 com IRA. A mortalidade foi mais elevada nos pacientes com IRA (59,7%) do que nos indivíduos com DRC (14,1%). No geral, os pacientes com hipernatremia tiveram mortalidade hospitalar mais elevada do que os indivíduos com valores normais de sódio (RRa: 1,82; IC 95%: 1,17-2,83). Os pacientes com hiponatremia não apresentaram mortalidade diferente (RRa: 0,19; IC 95%: 0,69-2,04). Também identificamos que hipercloremia (RRa: 1,35; IC 95%: 0,83-2,18) e hipocloremia (RRa: 0,66; IC 95%: 0,30-14,78) não elevaram a mortalidade em comparação a indivíduos com níveis normais de cloro. Não foi encontrada associação entre distúrbios do sódio ou do cloro e mortalidade hospitalar nos subgrupos com DRC e IRA. Conclusões: Em nossa análise exploratória, apenas hipernatremia apresentou associação com mortalidade hospitalar em pacientes com IRA ou DRC submetidos a hemodiálise aguda.

ABSTRACT

Abstract Objective: The purpose of this study was to compare the operative mortality rate and outcomes of endovascular aneurysm repair (EVAR) between young and geriatric people in a single center. Methods: Eighty-five patients with abdominal aortic aneurysms who underwent EVAR between January 2012 and September 2016 were included. Outcomes were compared between two groups: the young (aged < 65 years) and the geriatric (aged ≥ 65 years). The primary study outcome was technical success; the secondary endpoints were mortality and secondary interventions. The mean follow-up time was 36 months (3-60 months). Results: The study included 72 males and 13 females with a mean age of 71.08±8.6 years (range 49-85 years). Of the 85 patients analyzed, 18 (21.2%) were under 65 years old and 67 patients (78.8%) were over 65 years old. There was no statistically significant correlation between chronic disease and age. We found no statistically significant difference between aneurysm diameter, neck angle, neck length, or right and left iliac angles. The secondary intervention rate was 7% (six patients). The conversion to open surgery was necessary for only one patient and only three deaths were reported (3.5%). There was no statistically significant difference in the mortality and reintervention rates between the age groups. The three deaths occurred only in the geriatric group and two died secondary to rupture. Kidney failure was observed in three patients in the geriatric group (4.5%). Conclusion: Our single-center experience shows that EVAR can be used safely in both young and geriatric patients.

ABSTRACT

Resumen Objetivo: conocer la sobrevida del programa de trasplante renal en el Hospital Nacional de Niños, de enero 1978 a enero 2016. Métodos: estudio retrospectivo y descriptivo, en niños que recibieron un trasplante renal. Se recopiló la información de los expedientes clínicos. Se incluyeron pacientes menores de edad que tuvieran un injerto viable por al menos tres meses, pacientes con expediente pasivo completo y que brindaran el consentimiento informado. Resultados: se recopiló un total de 152 pacientes, y se incluyeron 143 en el estudio, ya que 9fueron excluidos. El 51 % (n= 73) fueron mujeres. Se realizó 167 trasplantes renales, el 63,5 % (n=105) fue de injertos provenientes de donante vivo relacionado. La sobrevida al primer año fue del 100 %, el 95 % a los 10 años y el 61% a los 20 años del trasplante. En cuanto a la sobrevida del injerto, se encontró una sobrevida al primer año del 95 %, del 76 % a los 3 años y del 73 % a los 5 años después del trasplante, con una incidencia de rechazo agudo del 28,7 %. Conclusión: el trasplante renal en niños es un procedimiento muy complejo donde la sobrevida depende de múltiples factores ambientales y adquiridos; sin embargo, sí es posible que centros pediátricos como el nuestro puedan llegar a alcanzar porcentajes de sobrevida acordes a los de centros de países desarrollados.


Abstract Objective: to know the survival of the renal transplant program at the National Children's Hospital, from January 1978 to January 2016. Methods: retrospective and descriptive study in children who received a kidney transplant. The information was compiled from the clinical files. We included children who had a viable graft for at least three months, patients with a complete passive file and who provided informed consent. Results: A total of 152 patients were collected, and 143 were included in the study, since 9 were excluded. 51% (n = 73) were women. A total of 167 kidney transplants were performed, 63.5% (n = 105) were grafts from a related living donor. Survival at the first year was 100%, 95% at 10 years and 61% at 20 years after transplantation. Regarding the survival of the graft, a survival rate of 95% was found in the first year, 76% at 3 years and 73% at 5 years after transplantation, with an incidence of acute rejection of 28.7%. Conclusions: Kidney transplantation in children is a very complex procedure where survival depends on multiple environmental factors and / or acquired, however it is possible that pediatric centers like ours can reach survival rates according to centers in developed countries.

ABSTRACT

Introducción: La Enfermedad Renal Crónica es un problema de salud mundial. Objetivo: Determinar el comportamiento de la mortalidad en pacientes con enfermedad renal en el Instituto de Nefrología durante 2016 y 2017. Material y Métodos: Estudio observacional descriptivo transversal de pacientes fallecidos con necropsia realizada. Se registraron variables demográficas, de laboratorio, las relacionadas con la terapia de reemplazo de la función renal y con el diagnóstico anatomo-patológico. Para cada una de las variables se calcularon frecuencias absolutas y relativas. En el caso de la variable presencia de sepsis en las defunciones, fue empleada la prueba de chi-cuadrado para la bondad del ajuste, para probar la hipótesis nula H0: de igualdad de la distribución de las tres categorías de la variable. Resultados: Se estudiaron 48 fallecidos con necropsia, 48,9 por ciento del total de fallecidos en el periodo. La correspondencia clínico patológica fue 80,1 por ciento. Predominó el sexo masculino, el grupo de edad superior a 60 años y la hipertensión arterial como antecedente. El método de terapia de reemplazo renal más documentado fue la hemodiálisis, mediante catéter venoso central un 87,8 por ciento. El 61,8 por ciento de los fallecidos recibieron tratamiento hemodialítico por 3 meses o menos. La sepsis fue la segunda causa de muerte precedida por eventos cardio y cerebrovasculares; no obstante, en el análisis de la totalidad de necropsias, la infección asociada directa o indirecta a la muerte tuvo una frecuencia mayor. Conclusiones: La infección directa o indirectamente asociada a la muerte, la hipoalbuminemia y el acceso vascular mediante catéter se relacionan con la mortalidad en el periodo(AU)


Introduction: Chronic kidney disease is a health problem worldwide. Objective: To determine the behavior of mortality in patients with kidney damage in the Nephrology Institute during the years between 2016 and 2017. Material and Method: A cross-sectional descriptive observational study was conducted in 48 deceased patients who underwent necropsy. Demographic and laboratory variables were recorded, as well as those related to the type of renal function replacement therapy and the anatomopathological diagnosis. Absolute and relative frequencies were calculated for each of the variables. In the case of the variable presence of sepsis in deaths, the Chi-Square Goodness-of-Fit Test was used to test the Null Hypothesis HO: uniformity of the distribution of the three categories of the variable. Results: A total of 48 deceased were studied at necropsy, representing 48.9 percent of the total number of deaths within the period. The clinical- pathological correlation was 80.1percent. The male sex, the group over the age of 60 years, and arterial hypertension as antecedent of the disease predominated in the study. The most documented method of renal function replacement therapy was hemodialysis which was performed through central venous catheter, 87.8 percent. The 61.8 percent of deceased patients received hemodialysis treatment for 3 months or less. Sepsis represented the second cause of death preceded by cardiovascular and cerebrovascular events. However, during the analysis of all the necropsies, the direct or indirect infection associated with the death had a greater frequency. Conclusions: Direct or indirect infections associated with death, hypoalbuminemia, and the vascular access with venous catheter was related to mortality during the observed period(AU)

Material and Methods: A retrospective cohort study was conducted in patients admitted to the chronic hemodialysis program at Hospital Antonio Lorena (Cusco-Peru), from 2010 to 2016. Kaplan-Meier method was used for the survival analysis to determine the factors associated with mortality, Cox´s Regression was carried out, obtaining Hazard Ratio (HR) and 95 percent confidence intervals (95 percent CI). Results: A total of 187 patients were studied, with a mean age of 57 years (interquartile range: 43-66). The 47 percent (89) of patients died during follow-up. Mortality rate was 24 deaths / 100 people-per year (95 percent CI: 19.6-29.6). The mean survival rate was 2.8 years (95 percent CI: 1.9-4.0). Dilatation of the left atrium in the echocardiography (HR: 2.63; 95 percent CI: 1.03-6.69; p=0.041), a white blood cell count ≥ 12x103u/mm3 (HR: 6.86; 95 percent CI: 2.08-22.66; p=0.002), and hemoglobin <7 g/dL (HR: 3.62; 95 percent CI: 1.05-12.48; p=0.041) were associated with mortality. Conclusions: A low frequency of survival was found, which was associated with potentially modifiable factors(AU)

ABSTRACT

Background. Chronic kidney disease (CKD) is increasingly recognised as an important cause of morbidity and mortality in South Africa (SA). Although the cost of dialysis is well documented in developed countries, little is known about this cost in sub-Saharan Africa. Objectives. To review the costs of providing peritoneal dialysis (PD) and haemodialysis (HD) at the Pietersburg renal dialysis public-private partnership (PPP) unit in Limpopo Province, SA. Methods. A retrospective review of the cost of inputs required for HD and PD was conducted from a provider's perspective, covering the period 2007 - 2012. A top-down approach was used to estimate the average annual cost per patient on HD and PD. Results. During the 6-year period under review, the number of patients on dialysis increased from 77 in 2007 to 182 in 2012. More than 60% of the patients were on HD. The average annual cost per patient was estimated to be ZAR212 286 (USD25 888) and ZAR255 076 (USD31 106) for HD and PD, respectively, in 2012. Personnel cost, PD supplies, HD supplies, the outsourcing fee and pharmaceutical supplies were the main cost drivers. PD proved to be more expensive than HD, despite the use of locally manufactured fluids. Conclusions. The study highlights the exceptionally high cost of dialysis treatment. Dialysis should be made more accessible by implementing measures to address the main cost drivers. Moreover, a comprehensive approach that includes prevention of CKD at primary healthcare level, an organ donation programme and an effective kidney transplant programme is urgently required in Limpopo. Further research is required to evaluate the cost-effectiveness of the PPP approach

ABSTRACT

ABSTRACT Background: Chronic kidney disease (CKD) and its associated high morbidity and mortality cause a significant economic burden and decreased quality of life in affected patients in Antigua, the rest of the Caribbean and globally. The causes of CKD in Antigua, morbidity and mortality factors affecting the sampled patients were evaluated with a view to formulating interventions to minimize the occurrence and the impact of these factors. Objective: To determine the causes of CKD over a nine-year period and the causes of morbidity and mortality among patients with CKD at the two main hospitals in Antigua. Methods: A retrospective review was done of the medical records of patients with CKD who were diagnosed between January 1, 2005 and December 1, 2013. Chronic kidney disease was defined as a glomerular filtration rate of less than 60 mL/minute/1.73 m2. The causes of CKD, the patients 'admission diagnoses, the causes of death and laboratory investigations were evaluated. Results: The documented causes of CKD in these patients were diabetes mellitus (51% of the patients), hypertension (26%), glomerulonephritis (5%) and lupus nephritis (4%). The causes of morbidity among the patients with CKD were myocardial infarction (5.1%), unstable angina (12.7%) and ischaemic stroke (12%). Contributing significantly to the patients 'morbidity were catheter-associated sepsis (8.1%, p < 0.001) and lower respiratory tract infections (5.4%). The main factors contributing to the patients 'mortality were myocardial infarction (16.7%) and catheter-associated sepsis (16.7%). Conclusion: This study documented that the most common causes of CKD among the sampled patients in Antigua were diabetes mellitus and hypertension. Ischaemic heart disease and infections were the major causes of morbidity and mortality among the patients. Early recognition and aggressive management of CKD and its risk factors and complications are important in reducing the clinical and economic burden associated with CKD.


RESUMEN Antecedentes: La enfermedad renal crónica (ERC) y su alta morbilidad y mortalidad asociadas, son causa de una importante carga económica y disminución de la calidad de vida entre los pacientes afectados en Antigua, el resto del Caribe y en todo el mundo. Se evaluaron las causas de la ERC en Antigua, así como los factores de morbilidad y mortalidad que afectan a los pacientes muestreados, con el fin de formular intervenciones encaminadas a minimizar la ocurrencia y el impacto de estos factores. Objetivo: Determinar las causas de la ERC durante un período de nueve años y las causas de morbilidad y mortalidad entre pacientes con ERC en los dos principales hospitales de Antigua. Métodos: Se realizó una revisión retrospectiva de las historias clínicas de los pacientes con ERC diagnosticados entre el 1 de enero de 2005 y el 1 de diciembre de 2013. La enfermedad renal crónica se definió como una tasa de filtración glomerular inferior a 60 ml/minuto/1.73 m2. Se evaluaron las causas de la ERC, los diagnósticos de admisión de los pacientes, así como las causas de muerte y las investigaciones de laboratorio. Resultados: Las causas documentadas de la ERC en estos pacientes fueron la diabetes mellitus (51% de los pacientes), la hipertensión (26%), la glomerulonefritis (5%), y la nefritis lúpica (4%). Las causas de morbilidad entre los pacientes con ERC fueron el infarto de miocardio (5.1%), la angina inestable (12.7%) y el accidente cerebrovascular isquémico (12%). La sepsis asociada con catéter (8.1%, p < 0.001) y las infecciones de las vías respiratorias inferiores (5.4%) contribuyeron significativamente a la morbilidad de los pacientes. Los principales factores que contribuyeron a la mortalidad de los pacientes fueron el infarto del miocardio (16.7%) y la sepsis asociada con catéter (16.7%). Conclusión: Este estudio documentó que las causas más comunes de ERC entre los pacientes incluidos en la muestra en Antigua fueron la diabetes mellitus y la hipertensión. La enfermedad cardíaca isquémica y las infecciones fueron las principales causas de morbilidad y mortalidad entre los pacientes. El diagnóstico temprano y el tratamiento agresivo de la ERC y sus factores y complicaciones de riesgo, son asuntos de importancia a la hora de reducir la carga clínica y económica asociadas con ERC.

ABSTRACT

Abstract Aim Amyloid A amyloidosis is a rare complication of chronic inflammatory conditions. Most patients with amyloid A amyloidosis present with nephropathy and it leads to renal failure and death. We studied clinical characteristics and survival in patients with amyloid A amyloidosis. Methods: A total of 81 patients (51 males, 30 females) with renal biopsy proven amyloid A amyloidosis were analyzed retrospectively. The patients were divided into good and poor outcomes groups according to survival results. Results: Most of the patients (55.6%) had nephrotic range proteinuria at diagnosis. Most frequent underlying disorders were familial Mediterranean fever (21.2%) and rheumatoid arthritis (10.6%) in the good outcome group and malignancy (20%) in the poor outcome group. Only diastolic blood pressure in the good outcome group and phosphorus level in the poor outcome group was higher. Serum creatinine levels increased after treatment in both groups, while proteinuria in the good outcome group decreased. Increase in serum creatinine and decrease in estimated glomerular filtration rate of the poor outcome group were more significant in the good outcome group. At the time of diagnosis 18.5% and 27.2% of all patients had advanced chronic kidney disease (stage 4 and 5, respectively). Median duration of renal survival was 65 ± 3.54 months. Among all patients, 27.1% were started dialysis treatment during the follow-up period and 7.4% of all patients underwent kidney transplantation. Higher levels of systolic blood pressure [hazard ratios 1.03, 95% confidence interval: 1-1.06, p = 0.036], serum creatinine (hazard ratios 1.25, 95% confidence interval: 1.07-1.46, p = 0.006) and urinary protein excretion (hazard ratios 1.08, 95% confidence interval: 1.01-1.16, p = 0.027) were predictors of end-stage renal disease. Median survival of patients with organ involvement was 50.3 ± 16 months. Conclusion Our study indicated that familial Mediterranean fever constituted a large proportion of cases and increased number of patients with idiopathic amyloid A amyloidosis. Additionally, it was observed that patient survival was not affected by different etiological causes in amyloid A amyloidosis.


Resumo Objetivo: A amiloidose AA é uma complicação rara de condições inflamatórias crônicas. A maior parte dos pacientes com amiloidose AA apresenta nefropatia, que leva à insuficiência renal e à morte. Estudaram-se as características clínicas e a sobrevida em pacientes com amiloidose AA. Métodos: Analisaram-se retrospectivamente 81 pacientes (51 homens, 30 mulheres) com amiloidose AA comprovada por biópsia renal. Os pacientes foram divididos em grupos de desfecho bom e ruim de acordo com os resultados de sobrevida. Resultados: A maior parte dos pacientes (55,6%) tinha proteinúria na faixa nefrótica no momento do diagnóstico. Os distúrbios subjacentes mais frequentes foram a febre familiar do Mediterrâneo (FFM, 21,2%) e a artrite reumatoide (10,6%) no grupo de desfecho bom e a malignidade (20%) no grupo de desfecho ruim. Somente a pressão arterial diastólica no grupo de desfecho bom e o nível de fósforo no grupo de desfecho ruim foram mais elevados. Os níveis séricos de creatinina aumentaram após o tratamento em ambos os grupos, enquanto a proteinúria diminuiu no grupo de desfecho bom. O aumento na creatinina sérica e a diminuição na TFGe do grupo de desfecho ruim foram mais significativos no grupo de desfecho bom. No momento do diagnóstico, 18,5% e 27,2% de todos os pacientes tinham doença renal crônica avançada (estágios 4 e 5, respectivamente). A duração média da sobrevida renal foi de 65 ± 3,54 meses. Entre todos os pacientes, 27,1% iniciaram tratamento de diálise durante o período de seguimento e 7,4% de todos os pacientes foram submetidos a transplante renal. Níveis elevados de pressão arterial sistólica [taxas de risco (HR) 1,03, intervalo de confiança (IC) de 95%: 1 a 1,06, p = 0,036], creatinina sérica (HR 1,25, IC 95%: 1,07 a 1,46, p = 0,006) e excreção urinária de proteínas (HR 1,08, IC 95%: 1,01 a 1,16, p = 0,027) foram preditores de doença renal terminal. A mediana da sobrevida de pacientes com comprometimento de órgãos foi de 50,3 ± 16 meses. Conclusão: O presente estudo indicou que a FFM constituiu uma grande proporção de casos e crescente quantidade de pacientes com amiloidose AA idiopática. Adicionalmente, observou-se que a sobrevida do paciente não foi afetada pelas diferentes causas etiológicas na amiloidose AA.

ABSTRACT

Fundamento: A insuficiência renal é comum em pacientes com insuficiência cardíaca crônica, com uma prevalência entre 20% a 57%, e está associada a um mau prognóstico e um alto risco de reinternações. Objetivo: O objetivo deste estudo foi apresentar características epidemiológicas, clínicas e terapêuticas de pacientes marroquinos com insuficiência cardíaca crônica que desenvolveram insuficiência renal crônica. Métodos: Foram avaliados 563 pacientes acompanhados por insuficiência cardíaca crônica na Unidade de Insuficiência Cardíaca do Departamento de Cardiologia do Hospital Universitário de Ibn Rushd em Casablanca, Marrocos, entre 30 de julho de 2012 e 30 de julho de 2016. Os pacientes foram divididos em dois grupos de acordo com a presença ou ausência de síndrome cardiorrenal. Resultados: Em comparação a pacientes que não desenvolveram síndrome cardiorrenal, os pacientes com síndrome cardiorrenal tenderam a ser mais velhos, hipertensos e diabéticos. Clinicamente, uma porcentagem mais alta dos pacientes apresentou dispneia estágio III ou IV. Biologicamente, os pacientes com SCR apresentaram níveis menores de hemoglobina e níveis plasmáticos maiores de ácido úrico. Em relação aos achados ecocardiográficos, esses pacientes também apresentaram menor FE do ventrículo esquerdo, com maior prevalência de hipertensão ventricular direita e hipertensão pulmonar, e maior risco de readmissão hospitalar (p < 0,0001). Conclusão: A deterioração da função renal na insuficiência renal crônica está associada com um pior prognóstico, incluindo um maior risco de readmissão hospitalar, eventos cardiovasculares, e morte. Maior atenção deve ser dada a pacientes idosos, diabéticos, com valores muito baixos de fração de ejeção do ventrículo esquerdo ou com hipertensão pulmonar


Background: Renal failure is common in patients with chronic heart failure, with a prevalence ranging from 20 % to 57% worldwide. It is associated with a poor prognosis and a high risk of readmission. Objectives: The purpose of our study is to show the epidemiological, clinical, paraclinical and therapeutic features of Moroccan patients with chronic heart failure who had developed a chronic renal failure. The endpoints were cardiac death and any cause of hospitalization. Methods: 563 patients followed for chronic heart failure at the heart failure unit in the Department of Cardiology of the University Hospital Ibn Rushd of Casablanca in Morocco, between July 30, 2012 and July 30, 2016 were assessed. Patients were divided into two groups according to the presence or absence of cardiorenal syndrome. Results: Compared to patients who had no cardiorenal syndrome, patients with cardiorenal syndrome tended to be more aged, hypertensive and diabetic. Clinically more patients were at dyspnea stage III or IV. Biologically their hemoglobin was lower and their blood uric acid level was higher. Regarding echocardiography, their ejection fraction of the left ventricle was lower, with more of systolic dysfunction of the right ventricle and pulmonary hypertension in the CRS group, with a higher risk of readmission (p < 0.0001). The mortality was significantly higher in the group CRS (p < 0.0001). Conclusion: The deterioration of renal function in chronic renal failure is associated with poor prognosis, including a high risk of rehospitalization, cardiovascular events and death. Patients who are elderly, diabetic, with a low left ventricular ejection fraction and pulmonary hypertension are the most concerned

ABSTRACT

Abstract Objective: The Oxford Classification for Immunoglobulin A nephropathy (IgAN) identifies pathological variables that may predict the decline of renal function. This study aimed to evaluate the Oxford Classification variables as predictors of renal dysfunction in a cohort of Brazilian children and adolescents with IgAN. Methods: A total of 54 patients with IgAN biopsied from 1982 to 2010 were assessed. Biopsies were re-evaluated and classified according to the Oxford Classification. Multivariate analysis of laboratory and pathological data was performed. The primary outcomes were decline of baseline estimated glomerular filtration rate (eGFR) greater than or equal to 50%. Results: Mean follow-up was 7.6 ± 5.0 years. Mean renal survival was 13.5 ± 0.8 years and probability of decline ≥50% in baseline eGFR was 8% at five years of follow-up and 15% at ten years. Ten children (18.5%) had a decline of baseline eGFR ≥ 50% and five (9.3%) evolved to end-stage renal disease. Kaplan-Meier analysis showed that baseline proteinuria, proteinuria during follow-up, endocapillary proliferation, and tubular atrophy/interstitial fibrosis were associated with the primary outcome. Multivariate Cox analysis showed that only baseline proteinuria (HR, 1.73; 95% CI, 1.20-2.50, p = 0.003) and endocapillary hypercellularity (HR, 37.18; 95% CI, 3.85-358.94, p = 0.002) were independent predictors of renal dysfunction. No other pathological variable was associated with eGFR decline in the multivariate analysis. Conclusion: This is the first cohort study that evaluated the predictive role of the Oxford Classification in pediatric patients with IgAN from South America. Endocapillary proliferation was the unique pathological feature that independently predicted renal outcome.


Resumo Objetivo: A Classificação Oxford para a Nefropatia por Imunoglobulina A (IgAN) identificou variáveis patológicas de risco para disfunção renal. O presente estudo teve como objetivo avaliar as variáveis da Classificação de Oxford como preditores de disfunção renal em crianças brasileiras com IgAN. Métodos: Foram analisados 54 pacientes com diagnóstico de IgAN entre 1982-2010. As biópsias renais foram reavaliadas pela Classificação de Oxford. Foram feitas análises uni e multivariada das variáveis clínicas e patológicas. O desfecho primário foi queda da taxa de filtração glomerular (TFG) ≥ 50% da filtração basal. Resultados: O acompanhamento médio foi de 7,6 ± 5,0 anos. A sobrevida renal média foi de 13,5 ± 0,8 anos e a probabilidade de atingir o desfecho primário foi de 8% em cinco anos e 15% em 10 anos de seguimento. Dez crianças (18,5%) apresentaram queda na TFG basal ≥ 50% e cinco (9,3%) evoluíram para doença renal crônica terminal. A análise de Kaplan-Meier mostrou que a proteinúria basal e de seguimento, a proliferação endocapilar e a atrofia tubular/fibrose intersticial foram associadas com o desfecho primário. A análise multivariada de Cox mostrou que a proteinúria basal (HR = 1,73; IC95% 1,20-2,50, p = 0,003) e a proliferação endocapilar (HR = 37,18; IC95% 3,85-358,94, p = 0,002) foram preditores independentes de disfunção renal. Nenhuma outra variável patológica foi associada com declínio da TFG na análise multivariada. Conclusão: Este é o primeiro estudo brasileiro que avaliou a Classificação Oxford em crianças com IgAN. A proliferação endocapilar foi a única característica patológica capaz de predizer independentemente o declínio da função renal.

ABSTRACT

ABSTRACT CONTEXT AND OBJECTIVE: Chronic kidney disease (CKD) has become an important public health issue. The socioeconomic burden of renal replacement therapy (RRT) is very high, as is CKD-related cardiovascular mortality and morbidity. Preventive and therapeutic measures only have modest impact and more research is needed. Few cohort studies have been conducted on populations with CKD. Our aim was to establish a cohort that would include more advanced forms of CKD (stages 3 and 4). Data collection was focused on renal and cardiovascular parameters. DESIGN AND SETTING: Prospective cohort study; São Paulo, Brazil. METHODS: Recruitment took place in Hospital das Clínicas, São Paulo, from March 2012 to December 2013. Data relating to medical history, food-frequency questionnaire, anthropometry, laboratory work-up, calcium score, echocardiography, carotid intimal-medial thickness, pulse-wave velocity, retinography and heart rate variability were collected. A biobank including serum, plasma, post-oral glucose tolerance test serum and plasma, urine (morning and 24-hour urine) and DNA was established. RESULTS: 454 participants (60% men and 50% diabetics) of mean age 68 years were enrolled. Their mean estimated glomerular filtration rate-CKD Epidemiology Collaboration was 38 ml/min/1.73 m2. Follow-up is ongoing and the main outcomes are the start of RRT, cardiovascular events and death. CONCLUSIONS: The PROGREDIR cohort is a promising prospective study that will allow better understanding of CKD determinants and validation of candidate biomarkers for the risks of CKD progression and mortality.


RESUMO CONTEXTO E OBJETIVO: A doença renal crônica (DRC) tornou-se um problema de saúde pública. A carga socioeconômica da terapia renal substitutiva é muito elevada, assim como a morbimortalidade cardiovascular associada à DRC. Medidas terapêuticas e preventivas têm impacto parcial e novos estudos são necessários. Há poucos estudos de coorte em populações com DRC. Nosso objetivo foi criar uma coorte que contemplasse formas mais avançadas de DRC (estágios 3 e 4). A coleta de dados foi centrada em parâmetros renais e cardiovasculares. TIPO DE ESTUDO E LOCAL: Estudo de coorte prospectivo; São Paulo, Brasil. MÉTODOS: O recrutamento ocorreu entre março de 2012 e dezembro de 2013, no Hospital das Clínicas, em São Paulo. Foram coletados dados de história médica, questionário de frequência alimentar, antropometria, exames laboratoriais, escore de cálcio, ecocardiografia, espessura de camada médio-intimal de carótidas, velocidade de onda de pulso, retinografia e variabilidade de frequência cardíaca. Um biobanco incluindo soro, plasma, soro e plasma pós-teste oral de tolerância à glicose, urina (manhã e 24 horas) e DNA foi estabelecido. RESULTADOS: 454 participantes (60% homens e 50% diabéticos) com idade média de 68 anos foram recrutados. A taxa média de filtração glomerular estimada-Colaboração da Epidemiologia para DRC foi de 38,4 ml/min/1,73 m2. O seguimento está em andamento e os desfechos principais são: início de terapia renal substitutiva, eventos cardiovasculares e óbito. CONCLUSÃO: A coorte PROGREDIR é um estudo prospectivo promissor que permitirá melhor compreensão dos determinantes de DRC e a validação de biomarcadores candidatos para o risco de progressão de DRC e de mortalidade.

ABSTRACT

Abstract Introduction: Chronic kidney disease (CKD) causes sudden changes in the daily lives of patients, creates limitations to perform activities of daily life and creates a great impact on emotions and quality of life (QOL) of patients. Objective: To understand the relationship between QOL of patients on dialysis and mortality rates, hospitalization and absences. Methods: A prospective descriptive study with 286 patients on hemodialysis, by applying demographic questionnaire, KDQOL SF-36 and electronic medical record analysis Dialsist. Results: The mean age was 54.71 ± 14.12 years, with a mean score of QOL 60.53 having as higher factor encouraging the support team (85.03) and lowest in work status (21.11). The days of hospitalization is negatively correlated to the compounds of the instrument, particularly in physical functioning (p = 0.000), mean score (p = 0.001) and emotional well-being (p = 0.005). Women had lower QOL in physical role scores, symptoms/problems, physical functioning, emotional well-being, energy and fatigue mean score (p ≤ 0.05). The lowest score was found to be related to treatment of patients in 1 year and 7 months and 5 years (59.93) and higher in patients with more than five years and one month (61.39). Conclusion: Hospitalizations decrease QV emotional and physical scores and absences are directly related to social support and age. The study looked through the data raise subsidies for the work of the aspects that need stimulation and adaptation in the lives of patients, providing a better balance in the individual's life.


Resumo Introdução: A doença renal crônica (DRC) acarreta mudanças repentinas no cotidiano dos pacientes, cria limitações para realizar as atividades de vida diária e gera um grande impacto nas emoções e na qualidade de vida (QV) do paciente. Objetivo: Compreender a relação entre a QV do paciente em hemodiálise e as taxas de mortalidade, hospitalização e faltas. Métodos: Estudo descritivo e prospectivo com 286 pacientes em hemodiálise, mediante aplicação de questionário sociodemográfico, KDQOL SF - 36 e análise de prontuário eletrônico Dialsist. Resultados: Idade média de 54,71 ± 14,12 anos, com escore médio de QV de 60,53, tendo como fator mais elevado o encorajamento da equipe de apoio (85,03) e menor em status de trabalho (21,11). Os dias de hospitalização se correlacionaram negativamente aos compostos do instrumento, principalmente no funcionamento físico (p = 0,000), escore médio (p = 0,001) e bem-estar emocional (p = 0,005). As mulheres apresentaram menor QV em escores de papel físico, sintomas/problemas, funcionamento físico, bem-estar emocional, energia fadiga e escore médio (p ≤ 0,05). O menor escore encontrado foi referente aos pacientes em tratamento entre 1 ano e 7 meses e 5 anos (59,93) e o maior em pacientes com mais de 5 anos e 1 mês (61,39). Conclusão: As hospitalizações diminuem a QV do quesito emocional e físico e as faltas estão diretamente relacionadas ao suporte social e à idade. O estudo buscou, por meio dos dados, levantar subsídios para o trabalho dos aspectos que necessitam de estimulação e adaptação na vida dos pacientes, proporcionando um maior equilíbrio na vida do indivíduo.

ABSTRACT

Introducción: las enfermedades renales constituyen una causa frecuente de consulta médica, de ingreso hospitalario y de mortalidad. Objetivo: analizar algunas variables demográficas, clínicas y anatomopatológicas en fallecidos por estas enfermedades durante 40 años en un servicio de Nefrología. Métodos: estudio retrospectivo y observacional de variables demográficas, clínicas y anatomopatológicas en 272 fallecidos del servicio de nefrología del hospital Dr. Luis Díaz Soto, a los que se les practicó autopsia, ocurridas de 1974 al 2013. Resultados: predominaron los pacientes masculinos, de piel blanca y con edades de 35 a 64 años. La edad promedio se ha ido incrementando. Los principales diagnósticos clínicos de causa directa de muerte fueron bronconeumonía, infarto agudo de miocardio y shock. Como causa básica se plantearon la insuficiencia renal crónica, la hipertensión arterial y la diabetes mellitus. En los estudios anatomopatológicos fueron señaladas como más frecuentes causas directas de la muerte la bronconeumonía, el edema pulmonar, el shock y el infarto agudo de miocardio; mientras que en los principales diagnósticos de causa básica de muerte fueron registrados el riñón terminal, la cardiopatía hipertensiva, la diabetes mellitus y la aterosclerosis. Conclusiones: los indicadores de mortalidad, necropsia y correspondencia clínico patológica fueron adecuados. Se apreció un incremento, progresivo en el tiempo, de la edad de los pacientes fallecidos estudiados. La bronconeumonía y las cardiopatías fueron las principales causas de muerte. Los signos de aterosclerosis estuvieron presentes en la mayoría de los estudios realizados(AU)


Introduction: Renal diseases are a frequent cause of medical consultation, hospitalization and mortality. Objective: Analyze some demographic, clinical and anatomical and pathological variables in the deaths of renal diseases during 40 years in a Nephrology service. Methods: A retrospective and observational study was conducted of demographic, clinical and anatomical and pathological variables in 272 deaths of the nephrology service at Dr. Luis Díaz Soto hospital, who were autopsied, from 1974 to 2013. Results: There were predominantly male patients, white skin and aged 35 to 64 years. The average age has been increasing. The main clinical diagnoses of direct cause of death were bronchopneumonia, acute myocardial infarction and shock. As a basic cause, chronic renal failure, arterial hypertension and diabetes mellitus were considered. In anatomical and pathological studies, bronchopneumonia, pulmonary edema, shock and acute myocardial infarction were identified as more frequent causes of death; while in the main diagnoses of the basic cause of death, the terminal kidney, hypertensive heart disease, diabetes mellitus, and atherosclerosis were documented. Conclusions: Mortality, necropsy, and clinical pathological correspondence indicators were adequate. There was a progressive increase in the age of the deceased patients studied. Bronchopneumonia and heart disease were the main causes of death. Signs of atherosclerosis were present in most of the studies(AU)

ABSTRACT

Doenças cardiovasculares são frequentes no curso da insuficiência renal crônica, constituem importante causa de óbito, e causam 1/3 das hospitalizações de doentes dialíticos. Hiperparatireoidismo secundárioé o distúrbio metabólico mais comum na insuficiência renal, cuja fisiopatologia envolve alterações no equilíbriodo cálcio, fósforo, calcitriol e paratormônio. Objetivo: Avaliar a prevalência de alterações ecocardiográficas em pacientes renais crônicos com hiperparatireoidismo secundário, de acordo com níveis plasmáticos de paratormônio.Métodos: Estudo retrospectivo, realizado com base em dados registrados em prontuários entre 2005 e 2007,incluindo 52 indivíduos de ambos os sexos, com doença renal crônica em programa regular de diálise, estratificados com base nos níveis plasmáticos de paratormônio em três grupos: Grupo I ≤ 299pg/mL (n=10); Grupo II entre 300-499 pg/mL (n=21); e Grupo III ≥500 pg/mL (n=21). Foram avaliados os seguintes parâmetros ecocardiográficos: diâmetros da raiz da aorta, do átrio esquerdo e dos ventrículos; espessuras do septo e da parede posterior; fração de ejeção; e volumes diastólico e sistólico finais.Resultados: A análise comparativa dos achados ecocardiográficos nos três grupos revelou que a única variávelque apresentou significância estatística (p 0,009) foi a espessura diastólica da parede posterior. Conclusão: Doentes renais crônicos com hiperparatireoidismo secundário podem apresentar alteraçõesecocardiográficas, algumas das quais apresentam correlação com níveis circulantes de paratormônio....


Background: Cardiovascular diseases are frequent in the course of chronic kidney disease, are an important cause of death, and cause 1/3 of hospitalizations of patients on dialysis. Secondary hyperparathyroidism is the most common metabolic disorder in kidney failure. Its pathophysiology involves changes in the balance of calcium, phosphorus, calcitriol and parathyroid hormone. Objective: To assess the prevalence of echocardiographic abnormalities in chronic kidney disease patients with secondaryhyperparathyroidism, according to plasma levels of parathyroid hormone.Methods: Retrospective study conducted based on data recorded in medical records between 2005 and 2007, including 52 individuals of both sexes with chronic kidney disease on a regular dialysis program, stratified based on plasma levels of parathyroid hormoneinto three groups: Group I ≤ 299pg/mL (n=10); Group II between 300-499 pg/mL (n=21); and Group III ≥500 pg/mL (n=21).We evaluated the following echocardiographic parameters: aortic root diameter, left atrial and ventricular diameter; septal and posteriorwall thickness; ejection fraction; and end diastolic and systolic volumes. Results: The comparative analysis of the echocardiographic findings in the three groups revealed that the only variable presenting statistical significance (p 0.009) was diastolic posterior wall thickness. Conclusion: Patients with chronic kidney disease with secondary hyperparathyroidism may present echocardiographic changes, some of which correlate with circulating levels of parathyroid hormone...

ABSTRACT

We investigated the prognostic effects of high-flux hemodialysis (HFHD) and low-flux hemodialysis (LFHD) in patients with chronic kidney disease (CKD). Both an electronic and a manual search were performed based on our rigorous inclusion and exclusion criteria to retrieve high-quality, relevant clinical studies from various scientific literature databases. Comprehensive meta-analysis 2.0 (CMA 2.0) was used for the quantitative analysis. We initially retrieved 227 studies from the database search. Following a multi-step screening process, eight high-quality studies were selected for our meta-analysis. These eight studies included 4967 patients with CKD (2416 patients in the HFHD group, 2551 patients in the LFHD group). The results of our meta-analysis showed that the all-cause death rate in the HFHD group was significantly lower than that in the LFHD group (OR=0.704, 95%CI=0.533-0.929, P=0.013). Additionally, the cardiovascular death rate in the HFHD group was significantly lower than that in the LFHD group (OR=0.731, 95%CI=0.616-0.866, P<0.001). The results of this meta-analysis clearly showed that HFHD decreases all-cause death and cardiovascular death rates in patients with CKD and that HFHD can therefore be implemented as one of the first therapy choices for CKD.
