ABSTRACT

Abstract In this study, we present two cases of cutaneous leishmaniasis in patients with end-stage renal disease, who were treated solely with intramuscular pentamidine. In such cases, treatment implies a fine line between therapeutic efficacy and toxicity. This is suggestive of a knowledge gap; however, findings indicate that this is still the fastest and safest alternative to the treatment with antimonials. Also, it can help avoid the side effects that occur upon using antimonials.

ABSTRACT

Resumen El síndrome cardiorrenal (SCR) es un trastorno en el que intervienen el corazón y los riñones, interactuando y produciendo una disfunción entre ellos en forma aguda o crónica. Existen diferentes fenotipos clínicos bien identificados como «desórdenes del corazón y riñón en los que la disfunción aguda o crónica en un órgano induce la disfunción aguda o crónica del otro¼. La alta incidencia de morbimortalidad cardiovascular presente en los pacientes con enfermedad renal crónica terminal (ERCT), en especial la insuficiencia cardiaca (IC), origina inicialmente una lesión miocárdica que conlleva remodelamiento ventricular, lo cual induce a la activación de mecanismos compensadores, entre los cuales el riñón es pieza fundamental, ya que regula la homeostasis hidroelectrolítica y así el volumen circulante, siendo esto en la etapa dialítica más evidente. Los cambios funcionales y anatómicos cardiovasculares que se producen en estos pacientes son muy prevalentes e incluyen las interacciones hemodinámicas del corazón y los riñones en la insuficiencia cardiaca, y el impacto de la enfermedad aterosclerótica en ambos sistemas de órganos. También describimos estrategias diagnósticas y terapéuticas aplicables al síndrome cardiorrenal, que determinan la importancia de la ecocardiografía como modelo de diagnóstico útil. Finalmente, se analizan las posibilidades de tratamiento y la remisión de las alteraciones funcionales cardiacas con el trasplante renal en los pacientes con ERCT.


Abstract Cardiorenal syndrome (CRS) is a disorder in which the heart and kidneys are involved, interacting and producing a dysfunction between them in an acute or chronic way. There are different clinical phenotypes well identified as "heart and kidney disorders in which acute or chronic dysfunction in one organ induces acute or chronic dysfunction in the other". The high incidence of cardiovascular morbimortality in patients with chronic terminal kidney disease (CKD), especially heart failure (HF), initially causes a myocardial lesion that leads to ventricular remodeling, which induces the activation of compensatory mechanisms, among which the kidney is a fundamental part since it regulates the hydroelectrolytic homeostasis and thus the circulating volume, being this in the dialytic stage more evident. The functional and anatomical changes at cardiovascular level that occur in these patients are very prevalent, and include hemodynamic interactions of the heart and kidneys in heart failure and the impact of atherosclerotic disease in both organ systems. We also describe diagnostic and therapeutic strategies applicable to cardiorenal syndrome, which determine the importance of echocardiography as a useful diagnostic model. Finally, we analyze the possibilities of treatment and remission of cardiac functional alterations with renal transplantation in patients with T-CKD.

ABSTRACT

Resumen La mucormicosis rino-órbito-cerebral (ROC) crónica es una patología poco frecuente, con un número reducido de casos publicados en la literatura, cuyas manifestaciones son muy diversas e inespecíficas. El tratamiento se basa en la experiencia de casos y series de casos. Las herramientas terapéuticas incluyen el uso de antifúngicos endovenosos y orales por tiempo prolongado, asociado o no a debridamiento quirúrgico amplio, pudiendo requerir incluso exenteración orbitaria. Presentamos a continuación un caso de mucormicosis ROC crónica, junto con las dificultades para su diagnóstico y manejo, en el que destaca el enfrentamiento multidisciplinario. Dada la poca frecuencia de esta enfermedad, nos parece relevante difundirlo.


Abstract Chronic rhino-orbital-cerebral mucormycosis is a rare condition with a small number of cases that have been published, whose manifestations are very diverse and nonspecific. The treatment is based on case series experiences. Therapeutic options include the use of long-term intravenous and oral antifungals, associated or not with extensive surgical debridement, and may even require orbital exenteration. We present below a case of chronic rhino-orbital-cerebral mucormycosis with the challenge of diagnosis and management in which multidisciplinary work is fundamental. Since it is an uncommon pathology, it seems relevant to share the information.

ABSTRACT

Abstract Tuberculosis is one of the most common infections worldwide with particularly high incidence rates in countries with unfavorable socioeconomic conditions and among persons with impaired immune systems. While most patients with this disease will present with pulmonary tuberculosis, immunocompromised individuals also commonly present with extrapulmonary manifestations. We report the case of a 28-year-old male patient with end-stage renal disease who presented with long-standing systemic symptoms and genitourinary manifestations, who was diagnosed with urogenital tuberculosis both by clinical and microbiologic criteria. Clinicians should always suspect tuberculosis in patients with chronic symptoms, especially in those with immunosuppression.

ABSTRACT

Abstract Background and objectives: Dilated cardiomyopathy is a state of progressive enlargement of cardiac chambers mainly left ventricle which leads to decreased cardiac output and ultimately cardiac failure. Although it has multifactorial etiology, it is quite common in patients with end stage renal disease who require renal transplant surgery for their cure. Both conditions go side by side and anesthetic management of such cases poses real challenge to anesthesiologist. Strict monitoring and control of cardiac physiology is of utmost importance besides meticulous fluid management, thus preserving renal blood flow on one hand and preventing cardiac failure on other hand. This is the basis of achieving good outcome of the renal transplant surgery. Methods: This is a retrospective observational study done by analysing electronic database of 31 patients with dilated cardiomyopathy who underwent renal transplant surgery. Data was studied in terms of demographics, duration of renal disease, comorbidities mainly hypertension, cardiac echo graphic findings including ejection fraction, medications and post-operative outcome. Results: Most common perioperative complication in this patient population was hypotension (51.61%) followed by pulmonary complications postoperative mechanical ventilation (12.9%) and pulmonary edema (6.45%). High incidence of hypotension may be a causative factor to increased rate of delayed graft functioning (12.9%) and acute tubular necrosis (2.23%) in these patients. Conclusion: Strict monitoring and control of hemodynamic parameters as well as meticulous fluid therapy is the cornerstone in improving outcome in patients with dilated cardiomyopathy undergoing renal transplant surgery.


Resumo Justificativa e objetivos A cardiomiopatia dilatada é um estado de aumento progressivo das câmaras cardíacas, principalmente do ventrículo esquerdo, que leva à diminuição do débito cardíaco e, por fim, à insuficiência cardíaca. Embora tenha etiologia multifatorial, é bastante comum em pacientes com doença renal terminal que precisam de transplante renal para sua cura. Ambas as condições andam lado a lado e o manejo anestésico de tais casos é um verdadeiro desafio para o anestesiologista. A monitoração e o controle rigoroso da fisiologia cardíaca são de extrema importância, além de um meticuloso manejo dos líquidos, o que por um lado preserva o fluxo sanguíneo renal, por outro previne a insuficiência cardíaca. Essa é a base para alcançar o bom resultado da cirurgia de transplante renal. Métodos Este estudo observacional retrospectivo foi feito mediante a análise de prontuários eletrônicos de 31 pacientes com cardiomiopatia dilatada submetidos à cirurgia de transplante renal. Os dados foram avaliados em termos demográficos, duração da doença renal, comorbidades (principalmente hipertensão), achados ecocardiográficos (inclusive fração de ejeção), medicamentos e resultados no pós-operatório. Resultados A complicação perioperatória mais comum nessa população de pacientes foi hipotensão (51,61%), seguida de complicações pulmonares, como ventilação mecânica pós-operatória (12,9%) e edema pulmonar (6,45%). A alta incidência de hipotensão pode ser um fator causador do aumento da incidência de atraso no funcionamento do enxerto (12,9%) e necrose tubular aguda (2,23%) nesses pacientes. Conclusão A monitoração rigorosa e o controle dos parâmetros hemodinâmicos, bem como a fluidoterapia criteriosa, são a pedra angular na melhoria dos resultados em pacientes com cardiomiopatia dilatada submetidos à cirurgia de transplante renal.

ABSTRACT

Background: Pregnancies in women with end stage renal failure are uncommon. However, correction of anemia and improvement in dialysis techniques increases the rate of successful pregnancies. Aim: To describe a 16 years' experience treating pregnant women on hemodialysis and to analyze maternal-fetal outcomes. Materials and Methods: Observational study of a dialysis center historical cohort in a university hospital, between 2001 and 2016. Results: Thirteen pregnancies were found in 11 women aged 23 to 32 years, 77% on dialysis prior to pregnancy. Residual diuresis was 1,300 [625-1,575] mL in 24 hrs. The baseline hemoglobin was 9.0 [7.6-9.9] g/dL and 92% of patients did not use contraception. The pre-dialysis blood urea nitrogen was 34 [29-36] mg /dL. An ultrasound to confirm pregnancy was done in all. At 23 [14-25] weeks of pregnancy, dialysis hours were increased, reaching 24 [19.5-24.0] hours per week. The most common complications were severe arterial hypertension (54%), severe anemia (46%), polyhydramnios (31%) and severe intrauterine growth retardation (IUGR) (23%). The median time of pregnancy at delivery was 34 [29-34] weeks. Neonatal median hospitalization length was 4 [4-32] days, with 18% of neonatal deaths. Conclusions: Pregnancies in dialysis are no longer exceptional. Despite better maternal and fetal outcomes, morbidity and mortality remains higher than in the normal population, which makes multidisciplinary management essential.

ABSTRACT

Abstract Mineral bone disorder is a common feature of chronic kidney disease. Lion face syndrome is rare complication of severe hyperparathyroidism in end-stage renal disease patients, which has been less commonly reported due to dialysis and medical treatment advances in the last decade. The early recognition of the characteristic facial deformity is crucial to prompt management and prevent severe disfigurement. The authors present a rare case of severe hyperparathyroidism presenting with lion face syndrome and bone fractures.


Resumo O distúrbio mineral e ósseo é uma característica comum da doença renal crônica. A síndrome da face leonina é uma complicação rara do hiperparatireoidismo grave em pacientes com doença renal terminal, que tem sido menos relatada devido aos avanços na diálise e tratamento médico na última década. O reconhecimento precoce da deformidade facial característica é crucial para estimular o tratamento precoce e prevenir a desfiguração severa. Os autores apresentam um caso raro de hiperparatireoidismo grave, apresentando síndrome da face leonina e fraturas ósseas.

ABSTRACT

ABSTRACT Introduction: Reliable markers to predict sudden cardiac death (SCD) in patients with end stage renal disease (ESRD) remain elusive, but echocardiogram (ECG) parameters may help stratify patients. Given their roles as markers for myocardial dispersion especially in high risk populations such as those with Brugada syndrome, we hypothesized that the Tpeak to Tend (TpTe) interval and TpTe/QT are independent risk factors for SCD in ESRD. Methods: Retrospective chart review was conducted on a cohort of patients with ESRD starting hemodialysis. Patients were US veterans who utilized the Veterans Affairs medical centers for health care. Average age of all participants was 66 years and the majority were males, consistent with a US veteran population. ECGs that were performed within 18 months of dialysis initiation were manually evaluated for TpTe and TpTe/QT. The primary outcomes were SCD and all-cause mortality, and these were assessed up to 5 years following dialysis initiation. Results: After exclusion criteria, 205 patients were identified, of whom 94 had a prolonged TpTe, and 61 had a prolonged TpTe/QT interval (not mutually exclusive). Overall mortality was 70.2% at 5 years and SCD was 15.2%. No significant difference was observed in the primary outcomes when examining TpTe (SCD: prolonged 16.0% vs. normal 14.4%, p=0.73; all-cause mortality: prolonged 55.3% vs. normal 47.7%, p=0.43). Likewise, no significant difference was found for TpTe/QT (SCD: prolonged 15.4% vs. normal 15.0%, p=0.51; all-cause mortality: prolonged 80.7% vs. normal 66.7%, p=0.39). Conclusions: In ESRD patients on hemodialysis, prolonged TpTe or TpTe/QT was not associated with a significant increase in SCD or all-cause mortality.


RESUMO Introdução: Marcadores confiáveis para predizer morte súbita cardíaca (MSC) em pacientes com doença renal terminal (DRT) permanecem elusivos, mas os parâmetros do ecocardiograma (ECG) podem ajudar a estratificar os pacientes. Devido a seus papéis como marcadores para a dispersão miocárdica, especialmente em populações de alto risco, como aquelas com síndrome de Brugada, nós hipotetizamos que o intervalo pico da onda T ao final da onda T (TpTe) e TpTe/QT são fatores de risco independentes para MSC na DRT. Métodos: Revisão retrospectiva do prontuário foi realizada em uma coorte de pacientes com DRT iniciando a hemodiálise. Os pacientes eram veteranos de guerra americanos que utilizavam os centros médicos do Veterans Affairs para atendimento médico. A idade média de todos os participantes foi de 66 anos e a maioria era do sexo masculino, consistente com uma população veterana dos EUA. ECGs que foram realizados dentro de 18 meses após o início da diálise, e foram avaliados manualmente para TpTe e TpTe/QT. Os desfechos primários foram MSC e mortalidade por todas as causas, e estes foram avaliados até 5 anos após o início da diálise. Resultados: Após o critério de exclusão, foram identificados 205 pacientes, dos quais 94 com TpTe prolongado e 61 com intervalo TpTe/QT prolongado (não mutuamente exclusivo). A mortalidade geral foi de 70,2% em 5 anos e a MSC foi de 15,2%. Nenhuma diferença significativa foi observada nos desfechos primários ao se avaliar o TpTe (MSC: prolongado 16,0% versus normal 14,4%, p = 0,73; mortalidade por todas as causas: prolongado 55,3% vs. normal 47,7%, p = 0,43). Da mesma forma, nenhuma diferença significativa foi encontrada para TpTe/QT (MSC: prolongado 15,4% vs. normal 15,0%, p = 0,51; mortalidade por todas as causas: prolongado 80,7% vs. normal 66,7%, p = 0,39). Conclusões: Em pacientes com insuficiência renal terminal em hemodiálise, TpTe ou TpTe/QT prolongados não foram associados a um aumento significativo da morte súbita ou mortalidade por todas as causas.

ABSTRACT

OBJECTIVES: To evaluate cardiovascular involvement in children and adolescents with End Stage Renal Disease (ESRD) and to characterize the main risk factors associated with this outcome. METHODS: Cross-sectional study of 69 children and adolescents at renal transplantation and 33 healthy individuals matched by age and gender. The study outcomes were left ventricular mass z-score (LVMZ) and carotid artery intima-media thickness (CIMT). The potential risk factors considered were age, gender, CKD etiology, use of oral vitamin D and calcium-based phosphate binders, systolic and diastolic blood pressure, body mass index z-score, time since diagnosis, dialysis duration, serum levels of ionic calcium, phosphorus, parathyroid hormone, fibroblast growth factor (FGF 23), uric acid, homocysteine, cholesterol, triglycerides, C-reactive protein (CRP), vitamin D and hemoglobin. RESULTS: In the multivariate analysis, the factors associated with LVMZ were dialysis duration, age, systolic blood pressure, serum hemoglobin and HDL cholesterol levels. Regarding CIMT, in the multivariate analysis, systolic blood pressure was the only factor associated with the outcome. CONCLUSION: Children exhibited important cardiovascular involvement at the time of the renal transplantation. Both of the studied outcomes were independently associated with systolic blood pressure. For this reason, controlling blood pressure seems to be the main therapy to minimize cardiovascular involvement in children with ESRD.

ABSTRACT

OBJECTIVES: We conducted this retrospective study to elucidate the clinical presentation and outcomes of anal abscess in chronic dialysis patients. METHODS: We performed a chart review of patients who were hospitalized for anal abscess from Jan. 2002 to Dec. 2015. A total of 3,074 episodes of anal abscess were identified. Of these, 43 chronic dialysis patients with first-time anal abscess were enrolled. Patients were divided into a surgical group and a nonsurgical group according to the treatment received during hospitalization. The baseline characteristics, clinical findings, treatments and outcomes were obtained and analyzed. The endpoints of this study were in-hospital mortality, one-year mortality and one-year recurrence. RESULTS: Of the 43 patients, 27 (62.7%) received surgical treatment, and 16 (37.2%) received antibiotic treatment alone. There was no significant difference in age, sex, body mass index, smoking habits, comorbidities, or dialysis characteristics between the two groups. Perianal abscess was the most common type of anal abscess, and 39.5% of patients experienced fistula formation. Most patients had mixed aerobic and anaerobic flora. Our data demonstrate that there was no significant difference in hospital stay, one-year survival or recurrence rate between the surgical group and nonsurgical group. However, there was a trend toward better in-hospital survival in patients who received surgical treatment (p=0.082). CONCLUSION: In chronic dialysis patients with anal abscess, there was no statistically significant difference in clinical presentation and outcomes between the surgical and nonsurgical groups, although the surgical group had a trend of better in-hospital survival.

ABSTRACT

ABSTRACT Restless legs syndrome (RLS) is a frequent complication of hemodialysis that has been associated with poor quality of life and increased risk for complications. Nevertheless, few studies regarding this entity exist in resource-limited settings. Objectives: To determine the prevalence of RLS among Mexican patients on hemodialysis; and compare these patients with a control group of the same population. Methods: We recruited 105 hemodialysis patients. Restless legs syndrome was diagnosed according to the updated criteria set out by the International RLS Study Group. We selected patients who did not meet the criteria, as controls. Results: We found an RLS prevalence of 18%. The RLS patients had a significantly higher prevalence of iron deficiency anemia and uremic pruritus. None of the patients reported RLS symptoms prior to hemodialysis initiation. Conclusions: Restless legs syndrome is common among Mexican patients on hemodialysis. Larger studies are required to address the impact of RLS in hemodialysis patients.


RESUMEN El síndrome de piernas inquietas (SPI) es una complicación de la hemodiálisis que se ha asociado con menor calidad de vida y riesgo aumentado de complicaciones. Sin embargo, existen pocos estudios acerca de esta entidad en escenarios de recursos limitados. Objetivos: Determinar la prevalencia de SPI en pacientes mexicanos en hemodiálisis, y comparar las características con un grupo control de la misma población. Métodos: Reclutamos 105 pacientes en hemodiálisis. El SPI se diagnosticó de acuerdo con los criterios actualizados del grupo de estudio internacional del síndrome de piernas inquietas. Seleccionamos a los pacientes que no cumplieron dichos criterios como controles. Resultados: Encontramos una prevalencia de SPI del 18%. Los pacientes con SPI tenían una prevalencia más alta de anemia ferropénica, y prurito urémico. Ninguno de los pacientes reportó síntomas de SPI previo a iniciar la hemodiálisis. Conclusiones: El SPI es frecuente en pacientes mexicanos en hemodiálisis; se requieren estudios más grandes para evaluar el impacto del síndrome en ésta población.

ABSTRACT

INTRODUCCIÓN: Existe una alta incidencia de fracturas en pacientes con enfermedad crónica terminal. Esto se debe en parte a la enfermedad óseo mineral del enfermo renal crónico y en parte a la alta prevalencia de debilidad muscular en esta población. OBJETIVO: Nuestro objetivo fue evaluar cuáles son los determinantes de fuerza muscular medida por fuerza de prensión palmar (FPP) en nuestra población de pacientes en hemodiálisis crónica. MATERIAL Y MÉTODOS: Estudio de corte transversal en adultos de un centro de hemodiálisis. Se registró la FPP y el índice de masa magra (IMM). Se registraron los valores de albumina, magnesio y otros parámetros serológicos. Utilizamos un análisis de regresión lineal múltiple para evaluar los predictores de FPP. RESULTADOS: Analizamos 139 pacientes (hombres: mujeres = 88:51, edad 60.7 ± 16), 18 fueron excluidos. La media de albúmina: 3.8 +/- 0.47 mg/dl, la mediana de tiempo en hemodiálisis: 37 meses (15-83), 25% (n= 35) fueron definidos como sarcopénicos y 21.5% (n= 30) tenían antecedentes de diabetes. En el análisis univariado el magnesio presentó correlación positiva con la FPP (ß 0.19 p 0.02). En el análisis multivariado todas las siguientes continuaron siendo correlativas con la FPP y estadísticamente significativas (R2 0.61 p <0.001): albumina (ß:.4.36 p 0.02), IMM (ß: 1.44 p <0.001), edad (ß -0.10 p 0.04), sexo (ß 6.21 p 0.007), diabetes (ß -5,08 p 0.005). CONCLUSIÓN: Edad, diabetes, albúmina, sexo e IMM están independientemente asociados con la FPP en pacientes en hemodiálisis. Los niveles séricos de magnesio presentaron asociación en el análisis univariado


INTRODUCTION: There is a great incidence of fractures in patients suffering from end-stage chronic disease. This is partly caused by chronic kidney disease-mineral bone disorder and partly by the high prevalence of muscle weakness in these patients. OBJECTIVE: Our objective was to identify the determining factors of muscle strength measured by means of handgrip strength (HGS) in chronic hemodialysis patients. METHODS: A cross-sectional study was conducted on adult patients in a hemodialysis center. Handgrip strength (HGS) and lean mass index (LMI) were measured, as well as albumin and magnesium values and other serological parameters. Multiple linear regression was used to assess HGS predictors. RESULTS: We analyzed 139 patients (88 men and 51 women; age: 60.7 ± 16); 18 subjects were excluded. Mean albumin values: 3.8 +/- 0.47 mg/dL; median hemodialysis time: 37 months (15-83). From the total number of patients, 25% (n=35) were found to be sarcopenic and 21.5% (n=30) had a history of diabetes. The univariate analysis showed a positive correlation between magnesium and HGS (ß 0.19 p 0.02). According to the multivariate analysis, all the following showed a correlation with HGS and were statistically significant: (R2 0.61 p <0.001): albumin (ß:.4.36 p 0.02); LMI (ß: 1.44 p <0.001); age (ß -0.10 p 0.04); sex (ß 6.21 p 0.007); diabetes (ß -5,08 p 0.005). CONCLUSION: Age, diabetes, albumin values, sex and LMI are independently associated with HGS in hemodialysis patients. Serum magnesium levels showed an association in the univariate analysis

ABSTRACT

ABSTRACT Cardiovascular disease (CVD) is one of the leading causes of mortality in hemodialysis (HD) subjects. In addition to the traditional risk factors that are common in these individuals, genetic factors are also involved, with emphasis on single nucleotide polymorphs (SNPs). In this context, the present study aims to systematically review the studies that investigated the polymorphisms associated with cardiovascular risk in this population. In general, the SNPs present in HD individuals are those of genes related to inflammation, oxidative stress and vascular calcification, also able of interfering in the cardiovascular risk of this population. In addition, polymorphisms in genes related to recognized risk factors for CVD, such as dyslipidemia, arterial hypertension and left ventricular hypertrophy, also influence cardiovascular morbidity and mortality.


RESUMO A doença cardiovascular (DCV) é uma das principais causas de mortalidade de indivíduos em hemodiálise (HD). Além dos fatores de risco tradicionais, que são frequentes nesses indivíduos, também estão envolvidos fatores genéticos, com destaque para os polimorfismos de nucleotídeo único (do inglês, single nucleotide polymorphism, SNP). O presente trabalho tem como objetivo revisar sistematicamente os estudos que investigaram os polimorfismos associados ao risco cardiovascular nessa população. De modo geral, os SNPs presentes em indivíduos em HD são aqueles de genes relacionados à inflamação, estresse oxidativo e calcificação vascular, também capazes de interferir no risco cardiovascular dos pacientes. Polimorfismos em genes relacionados a fatores de risco reconhecidos para DCV, como dislipidemia, hipertensão arterial e hipertrofia ventricular esquerda, também influenciam a morbidade e mortalidade cardiovascular.

ABSTRACT

SUMMARY AIM: Uremic toxins and excess fluid contributes to increased cardiovascular (CV) risk. We aimed to determine the body fluid status in patients who are just starting hemodialysis (HD) and to determine the effects of excess fluid removed by HD on the CV system. METHODS: A total of 52 patients with chronic kidney disease (CKD) who had just started HD were included. Before the HD, the left atrial diameter was measured, the volumes were calculated, the pulse wave velocity (PWV) and the augmentation index (AIx) were measured, the bioimpedance analysis (BIA) was performed, the blood was taken for brain natriuretic peptide (BNP). When patients reached their dry weight with HD, the same measurements were repeated. RESULTS: Measurements were made to determine the volume status, and all parameters except the fat tissue index decreased significantly after HD. With the removal of fluid by HD, there was an average weight reduction of 4.38 kilograms. Positive correlations between PWV and age and cardiothoracic ratio (CTR) before HD were determined. Negative correlations were found between PWV and lean tissue mass (LTM) and intracellular water (ICW) before HD. At the end of the last HD, PWV was positively correlated with age, CTR, central pulse pressure Correlation between pulse wave velocity and LTI was negative CONCLUSIONS: HD significantly improves PWV in patients reaching dry weight. Reduction of fluid excess by ultrafiltration in HD patients may reduce CV mortality by reducing arterial stiffness.


RESUMO INTRODUÇÃO: Em pacientes com doença renal crônica (DRC), toxinas urêmicas e hipervolemia contribuem para aumentar o risco cardiovascular. Nosso objetivo foi determinar o estado de hidratação em pacientes com DRC iniciando hemodiálise (HD) e avaliar os efeitos da correção da hipervolemia sobre o sistema cardiovascular. MÉTODOS: Foram incluídos 52 pacientes que haviam acabado de iniciar HD. Antes do início da sessão, foram determinados o diâmetro e o volume atrial esquerdo, a velocidade de onda de pulso (VOP) e o índice de amplificação sistólica ("augmentation index", AI). Além disso, realizamos análise da composição corporal por bioimpedância elétrica (BIA) e mensuramos os níveis plasmáticos de peptídeo natriurético tipo B. Os mesmos procedimentos foram repetidos após os pacientes alcançarem o "peso seco". RESULTADOS: O peso corporal dos pacientes foi reduzido, em média, em 4,38 kg. Na BIA, todos os parâmetros, exceto o índice de gordura corporal, foram significativamente reduzidos após a hemodiálise. Antes da HD, a VOP se correlacionou positivamente com idade e razão cardiotorácica (RCT), e negativamente com a massa magra e a água intracelular. Ao final da hemodiálise, a VOP se correlacionou positivamente com idade, RCTe pressão de pulso central, correlacionando-se negativamente com a Lean Tissue Index (LTI). CONCLUSÃO: A hemodiálise melhora a VOP por meio da redução da volemia. O controle da hipervolemia via ultrafiltração pode reduzir a mortalidade cardiovascular por meio da redução da rigidez arterial.

ABSTRACT

ABSTRACT Purpose The study aims to assess the influence of the stage of chronic kidney disease and glomerular filtration rate on prevalence and degree of erectile dysfunction. Materials and Methods This transversal study, conducted from May 2013 to December 2015, included patients with chronic kidney disease in conservative treatment, stages III/IV/V. Erectile dysfunction was evaluated by the International Index of Erectile Function. Data classically associated with erectile dysfunction were obtained by medical record review. Erectile dysfunction, degree of erectile dysfunction, and other main variables associated with erectile dysfunction were compared between patients with chronic kidney disease on conservative treatment stages III versus IV/V using the Chi-square test. The relationship between score of the International Index of Erectile Dysfunction and glomerular filtration rate was established by Pearson correlation coefficient. Results Two hundred and forty five patients with chronic kidney disease in conservative treatment participated of the study. The prevalence of erectile dysfunction in patients with chronic kidney disease in stages IV/V was greater than in stage III. Glomerular filtration rate positively correlated with score of the International Index of Erectile Dysfunction. Conclusions The study suggests that chronic kidney disease progression (glomerular filtration rate decrease and advance in chronic kidney disease stages) worsen erectile function. Hypothetically, diagnosis and treatment of erectile dysfunction may be anticipated with the analysis of chronic kidney disease progression.

ABSTRACT

Resumo O presente estudo buscou observar a tendência de mortalidade por insuficiência renal crônica (IRC) e verificar as causas básicas e associadas na capital do Acre, Amazônia brasileira. Para tanto, foi realizado um estudo ecológico com dados de óbitos por IRC do DATASUS ocorridos entre 1986 e 2012, em ambos os sexos de residentes em Rio Branco, Acre. Estimou-se a variação anual percentual (Estimated Annual Percentage Chance - EAPC) com a técnica de regressão log-linear de Poisson do programa Joinpoint. Os resultados demonstraram que as taxas de mortalidade ajustadas da IRC com correção variaram de 15,4 por 100.000 hab., em 1986, para 4,0 por 100.000 hab., em 2012. A EAPC foi de -3,5%, de 1986 a 2012. Os óbitos pela IRC apresentaram como causas associadas às doenças respiratórias, pneumonia e edema pulmonar, às septicemias e aos sinais e sintomas mal definidos. Quando analisada a IRC como causa associada, as principais causas básicas do óbito foram as doenças hipertensivas e o diabetes. Assim, houve redução da mortalidade por insuficiência renal crônica como causa básica no período observado, contudo medidas de prevenção e assistência em saúde devem ser mantidas.


Abstract This study examined the mortality trend due to chronic renal failure (CRF) and verified the underlying and associated causes for this trend in the capital of the state of Acre in the Brazilian Amazon. This ecological study used data provided by DATASUS related to mortality due to CRF, which occurred between 1986 and 2012 for male and female residents of the city of Rio Branco, Acre, Brazil. The estimated annual percentage chance (EAPC) was calculated by using Poisson log-linear regression and utilizing the Joinpoint program. The results showed that the adjusted mortality rates due to CRF, with correction, ranged from 15.4 per 100,000 inhabitants in 1986 to 4.0 per 100,000 inhabitants in 2012. The EAPC was -3.5% from 1986- 2012. Deaths by CRF presented associated causes such as respiratory diseases, pneumonia and pulmonary edema, septicemias and poorly defined signs and symptoms. When CRF was analyzed as an associated cause of death, the main primary causes of death were hypertensive diseases and diabetes. Thus, there was a decrease in mortality due to CRF as an underlying cause during the period studied; however, preventive and heath care measures should be maintained.
