Predisposition to acute pancreatitis in dogs with severe acute renal failure

ABSTRACT: Patients with acute renal failure often have a negative energy balance, which promotes metabolic changes predisposing to complications. The objective of this study was to evaluate laboratory parameters of 30 dogs with severe acute renal failure, to assess their relationship with the possibility of developing acute pancreatitis due to the negative energy balance, and to correlate these findings with the degree of renal failure. Serum concentrations of urea, creatinine, beta-hydroxybutyrate, triglycerides, amylase, total lipase, and canine pancreatic lipase were compared between healthy dogs and dogs with severe acute renal failure. A greater serum concentration of beta-hydroxybutyrate and greater activity of pancreatic enzymes, particularly canine pancreatic lipase, as well as a stronger correlation between the latter and serum creatinine concentrations, were related to the occurrence of acute pancreatitis in patients with severe acute renal failure. A greater degree of renal failure implied a greater predisposition to acute pancreatitis.

RESUMO: O portador de insuficiência renal aguda é um paciente que, muitas vezes, encontra-se sob importante condição de balanço energético negativo, gerando alterações metabólicas que predispõem a complicações. O objetivo deste estudo foi avaliar parâmetros laboratoriais de trinta cães com insuficiência renal aguda grave, quanto a possibilidade de desenvolvimento de pancreatite aguda em função do balanço energético negativo, e relacioná-los ao grau de gravidade da insuficiência renal. As concentrações séricas de ureia, creatinina, betahidroxibutirato, triglicérides, amilase, lipase total e lipase pancreática canina foram comparadas entre o grupo de cães hígidos e o de cães doentes. Observou-se maior concentração sérica de betahidroxibutirato e maior atividade das enzimas pancreáticas, especialmente da lipase pancreática canina, além de forte correlação entre esta última e a concentração sérica de creatinina, demonstrando a ocorrência de pancreatite aguda em pacientes com insuficiência renal aguda grave. Verificou-se também que quanto mais grave é a insuficiência renal, maior é a predisposição à pancreatite aguda.

The risk analysis of acute renal insufficiency in perioperative of non-small cell lung cancer / 中华胸心血管外科杂志

Objective To discover the risk factors of acute renal insufficiency(ARI) in perioperative of non-small cell lung cancer(NSCLC).Methods We took a retrospective study to analysis and summarize the clinical features of 33 ARI cases and 721 controls,all subjects were histopathologically confirmed NSCLC from January 2007 to October 2013.Logistic regression analysis was conducted to analyze the association between the risk factors and ARI.Results There were significant differences between the two groups in operation age,level of preoperative creatinine,preoperative rehydration and the use of plasma substitutes.After adjustment by confounding factors,operation age older than 60 years old and the use of plasma substitutes had higher risk of ARI [adjusted OR was 2.93 (1.30-6.62),95 ％ CI was 6.04 (1.41-25.87),respectively].Preoperative rehydration was protective factor of ARI(adjusted OR was 0.37,95％ CI was 0.17-0.83).Conclusion Operation age (≥ 60 years old) and the use of blood substitutes are independent risk factors of ARI,while preoperative rehydration can reduce the incidence of ARI after surgery.

Uso do eculizumab na síndrome hemolítica urêmica atípica: relato de caso e revisão da literatura / Eculizumab for the treatment of atypical hemolytic uremic syndrome: case report and revision of the literature

Síndrome Hemolítico Urêmica atípica (SHUa), isto é, não associada à Escherichia coli, produtora de Shiga toxina, é vista em 5% a 10% dos casos de Síndrome Hemolítico Urêmica (SHU), podendo ocorrer em qualquer idade e ser esporádica ou familiar. O prognóstico nestes casos é reservado, com alta mortalidade e morbidade na fase aguda da doença, e cerca de 50% dos casos podem evoluir para doença renal crônica terminal. O aumento do conhecimento da patôgenese da SHUa (hiperativação da via alternativa do complemento) foi acompanhado pelo surgimento de uma droga, eculizumab, a qual age como inibidor da via final do complemento. Nosso objetivo é relatar um caso de lactente com SHUa que apresentou excelente resposta clínica e laboratorial com o uso de eculizumab. Lactente, 14 meses de idade, sexo masculino, previamente hígido, apresentou quadro de anemia e plaquetopenia aos 12 meses de idade. Foi tratado com corticoterapia e encaminhado ao nosso serviço por hipertensão arterial. Entretanto, os exames demonstraram acometimento renal com proteinúria nefrótica e hipoalbuminemia, com Coombs direto negativo. Evoluiu com anemia, plaquetopenia, piora de função renal e hipertensão. Realizada biópsia renal que mostrou microangiopatia trombótica (MAT). Diante do quadro de anemia não hemolítica, plaquetopenia e insuficiência renal aguda com substrato histológico de MAT, foi feito diagnóstico de SHUa. O paciente recebeu eculizumab, com excelente resposta clínico-laboratorial. Este caso denota a importância de diagnóstico e tratamento precoces nesta entidade grave que é a SHUa. Eculizumab é eficaz e mantém remissão a longo prazo, evitando medidas invasivas como a plasmaferese, a qual resolve apenas parcialmente o quadro.

SHU atypical (aHUS), that is, not associated with Escherichia coli Shiga toxinproducing, is seen in 5 to 10% of cases of Hemolytic Uremic Syndrome (HUS), and can occur at any age and may be sporadic or familial. The prognosis in these cases is reserved, with high mortality and morbidity in the acute phase of the disease, and about 50% of cases can develop chronic kidney disease. The increased knowledge of the pathogenesis of aHUS (overactivation of the alternative pathway of complement), was accompanied by the appearance of a drug, eculizumab, which acts as an inhibitor of membrane attack complex. Our goal is to report a case of infant with aHUS with excellent clinical and laboratory response with the use of eculizumab. 14 month old infant, previously healthy, male, presented anemia and thrombocytopenia at 12 months of age. He was treated with corticosteroids and forwarded to our service for high blood pressure. However, the scans showed nephrotic proteinuria with renal involvement and hypoalbuminemia with direct Coombs negative. He developed anemia, thrombocytopenia, worsening of renal function and hypertension. Renal biopsy showed thrombotic microangiopathy (TMA). On the non-hemolytic anemia, thrombocytopenia and acute renal failure with histological substrate MAT, was diagnosed of aHUS. The patient received eculizumab excellent clinical and laboratory response. This case shows the importance of early diagnosis and treatment of the aHUS. Eculizumab is effective and keeps long-term remission, avoiding invasive measures such as plasmapheresis, which resolves only part of the picture.

Insuficiencia renal aguda en ancianos atendidos en cuidados intensivos del Hospital Territorial Docente Julio M. Arístegui Villamil. Cárdenas. 2006-2011 / Acute renal insufficiency in elder people attended at the Intensive Care Unit of the Teaching Territorial Hospital Julio M. Aristegui Villamil. Cárdenas. 2006-2011

La insuficiencia renal aguda es un problema médico habitual en la práctica clínica, tanto fuera como dentro del hospital, en la unidad de cuidados intensivos está asociado a un incremento de la morbimortalidad. Con el fin de caracterizar su comportamiento, se realizó un estudio descriptivo, transversal, en pacientes mayores de 60 años ingresados en la Unidad de Cuidados Intensivos del Hospital Julio Arístegui Villamil, de Cárdenas, en el período comprendido desde 1 enero de 2006 hasta 1 de enero de 2011, los cuales, según la clasificación RIFLE, desarrollaron fallo renal agudo. La muestra estuvo conformada por 68 pacientes (52 %); existió un predominio del sexo masculino con respecto al femenino, (3:1) y del color de piel blanca (72 %). La localización de la lesión predominante fue la parenquimatosa (63 %) seguida de la postrenal. El 45,5 % recibió tratamiento sustitutivo de la función renal. La mortalidad fue elevada (57 %), siendo las principales causas de muerte: el fallo múltiple de órganos y la sepsis.

The acute renal insufficiency is a customary medical problem in the medical practice as much inside as out the hospital; in the Intensive Care Unit it is associated to an increase of the morbimortality. With the objective of characterizing its behavior, we carried out a descriptive, crossed study in more-than-60-years-old patients who entered the Intensive Care Unit of the Hospital Julio Aristegui Villamil, of Cardenas, in the period from January 1st 2006 to January 1st 2011, and developed an acute renal failure according to the RIFLE classification. The sample was formed by 68 patients (52 %); there it was a predomination of the male sex over the female (3:1) and of the white race (72 %). The predominant location of the lesion was the parenchymatous one (63 %) followed by the post-renal one. 45,5 % of the patients received a substitutive treatment of the renal function. The mortality was high (57 %), being the multiple organic failure and sepsis the main death causes.

Uso de nifedipina e incidência de lesão renal aguda em pós-operatório de cirurgia de revascularização do miocárdio com CEC / Use of nefidipine and acute kidney injury incidence in postoperative of myocardial revascularization surgery with cardiopulmonary bypass

OBJETIVO: Avaliar durante o período perioperatório o uso da nifedipina na incidência de lesão renal aguda dos pacientes submetidos à revascularização do miocárdio com circulação extracorpórea. MÉTODOS: Foram estudados, de modo prospectivo e sequencial, 94 pacientes submetidos à revascularização do miocárdio com circulação extracorpórea. As dosagens da creatinina sérica foram realizadas durante pré-operatório e pós-operatório de 24, 48 horas e no 7º dia. Estabeleceu-se como definição para presença de lesão renal a elevação da creatinina sérica 30 por cento em relação ao seu valor basal nas primeiras 24 ou 48 horas de pós-operatório. Os pacientes foram divididos em quatro grupos: G1, que recebeu nifedipina no pré-operatório; G2, que recebeu nifedipina no pós-operatório; G3, que recebeu nifedipina no pré e pós-operatórios e, G4, que não recebeu nifedipina. RESULTADOS: O grupo G4 mostrou maior elevação do percentual de creatinina sérica e maior percentual de pacientes que apresentaram insuficiência renal aguda em relação aos demais grupos no pós-operatório. CONCLUSÃO: Os valores da creatinina sérica e a incidência de lesão renal aguda no pós-operatório sugerem possível efeito nefroprotetor da nifedipina em pacientes submetidos à revascularização do miocárdio com circulação extracorpórea.

OBJECTIVE: The objective of this work was to evaluate the influence of the use of nifedipine on the outcome of renal function in patients undergoing myocardial revascularization with extracorporeal circulation. METHODS: The casuistics and variables related to extracorporeal circulation were studied. Serum creatinine levels were measured preoperatively, 24, 48 hours and on 7th day postoperatively. Renal failure was defined as an increase in 30 percent of serum creatinine levels at 24 or 48 hours postoperatively compared to those at baseline. Patients were assigned to four groups: G1 (patients who received nifedipine preoperatively); G2 (patients who received nifedipine postoperatively); G3 (patients who received nifedipine pre and postoperatively) and G4 (patients who did not receive nifedipine). RESULTS: The mean serum creatinine levels postoperatively presented greater rise in G4 (G4>G1=G2=G3), and G4 also presented a higher percentage of patients with acute renal failure (G4>G1 and G4>G3, P<0.05; G1=G3 and G2=G4, P>0.05). CONCLUSION: The evaluation of serum creatinine values and incidence of acute kidney injury postoperatively suggest a possible nefro-potective effect of nifedipine in patients undergoing myocardial revascularization with extracorporeal circulation.

Evaluación nutricional de niños con insuficiencia renal aguda que reciben diálisis / Nutritional assessment of children presenting with acute renal insufficiency and underwent to dialysis

INTRODUCCIÓN. La insuficiencia renal aguda se produce en horas o en algunos días, y durante su evolución se produce un deterioro del estado nutricional del paciente. El objetivo de este estudio fue caracterizar el estado nutricional de niños con esta enfermedad que requirieron terapias de reemplazo renal. MÉTODOS. Se realizó un estudio retrospectivo y transversal que incluyó a los pacientes ingresados por insuficiencia renal aguda en dos hospitales pediátricos de Santiago de Cuba entre diciembre de 2006 y diciembre de 2008. Se analizó edad, sexo, etiología, terapia de reemplazo renal, causa del uso de nutrición parenteral, evaluación nutricional según tablas cubanas de percentiles y parámetros antropométricos (edad, peso, talla) y aporte de nutrientes parenterales. RESULTADOS. Eventos prerrenales fueron la causa de la insuficiencia renal aguda en el 44,4 por ciento de los casos, y renales y posrenales, en el 33,4 y 22,2 por ciento, respectivamente. Como método de depuración renal se utilizó la diálisis peritoneal en el 66,6 por ciento de los casos y la hemodiálisis en los restantes pacientes. Las principales causas que motivaron la nutrición parenteral fueron las afecciones quirúrgicas, los estados hipercatabólicos, la hemorragia digestiva y la pancreatitis, en orden decreciente. Cuatro pacientes fueron evaluados como de bajo peso. CONCLUSIONES. El aporte promedio de proteínas y lípidos estuvo por debajo de los aportes nutricionales establecidos, y el aporte de kilocalorías fue superior a lo recomendado. Se deben mejorar estos parámetros en el tratamiento de estos pacientes

INTRODUCTION: Acute renal insufficiency appears in hours or in a few days and during its course there is a deterioration of patient nutritional status. The aim of present study was to characterize the nutritional status of children with this disease requiring renal replacement therapies. METHODS: A crossed-sectional and retrospective study was conducted including the patients admitted due to acute renal insufficiency in two children hospitals of Santiago de Cuba from December, 2006 to December, 2008. Authors analyzed the age, sex, etiology, renal replacement therapy, cause of parenteral feeding use, nutritional assessment according to Cuban percentile tables and anthropometry parameters (age, weight, height) and parenteral nutrients support. RESULTS: Prerenal events were the cause of acute renal insufficiency in the 44,4 percent of cases and renal and postrenal ones in the 33,4 percent and 22,2 percent, respectively. As a renal depuration method we used the peritoneal dialysis in the 66,6 percent of cases and the hemodialysis in remainder. The main causes that justified the parenteral feeding were the surgical affections, hypercatabolic states, the digestive hemorrhage and the pancreatitis in a decreasing order. Four patients were assessed as of low weight. CONCLUSIONS: The average support of proteins and lipids was under the established nutritional supports and that of kilocalories was higher than recommended. It is essential to improve these parameters in the treatment of these patients

Comments on clinical and laboratory characteristics and some risks factors of neonatal acute renal failure

Background: Acute renal failure is a common emergency and esspecial dangerous in the neonatal disease group, account for from 8% to 24% of among total patients to be treated at Intensive Care Unit with the high rate of mortality and complication. The mortality rate due to acute renal failure in neonatal group account for from 24.4% to 66,7%. Objectives: This study aims to learn about the clinical and laboratory characteristics as well as some risks factors of neonatal acute renal failure. Subjects and method:A descriptive, retrospective study was conduct on 64 patients without diagnosed of acute renal failure in control group and other 32 cases of acute renal failure whom treated at Neonatal Department of National Hospital for Pediatric from 1st January 2005 to 31st March 2006.
