ABSTRACT

Resumen El síndrome de DRESS (Reacción a drogas con eosinofilia y síntomas sistémicos) es una patología poco frecuente en Pediatría, descrita por primera vez en 1996, por Bocquet. Puede presentarse en un tiempo variable luego de exposición a algunos medicamentos, se caracteriza por fiebre, compromiso cutáneo y de órganos internos. En este caso, se presenta a un paciente de 13 años, con antecedente de uso de Trimetroprim sulfa desde hace 2 meses, con cuadro de 3 días consistente en fiebre y rash cutáneo, sin compromiso de mucosas, con respuesta no favorable al manejo con esteroide, requiriendo Inmunoglobulina IV. Semanas después del inicio de los síntomas y evolución estable presenta insuficiencia renal aguda que requirió terapia de reemplazo renal. Se descartaron otras patologías subyacentes de índole autoinmune. Hubo recuperación de azoados y normalización de los demás paraclínicos el día 40 de la enfermedad. El paciente continúa asintomático, 4 meses después, con tratamiento con esteroide oral, en descenso lento y gradual. Se debe considerar la evaluación permanente de las pruebas de función renal en los pacientes que presenten Síndrome de DRESS, por su asociación con Nefritis intersticial aguda y complicaciones relacionadas.


Abstract DRESS syndrome (Drug Reaction with Eosinophilia and Systemic Symptoms) is a rare pathology in Pediatrics, first described in 1996 by Bocquet. It can appear in a variable period of time after exposure to some medications, it is characterized by fever, skin involvement and internal organs. A 13-year-old patient is presented, with a history of use of Trimethoprim sulfa for two months, with a disease of three days of evolution, consisting of fever and skin rash, without mucosal involvement, with an unfavorable response to steroid management, requiring Intravenous inmunoglobulin. Weeks after the onset of symptoms and stable evolution, he presented acute renal failure that required renal replacement therapy. Other underlying autoimmune pathologies were ruled out. There was recovery of renal function test and normalization of the other paraclinical on day 40 of the disease. Patient remains asymptomatic four months later, with oral steroid treatment, in slow and gradual decline. Permanent evaluation of renal function tests should be considered in patients with DRESS syndrome, due to its association with acute tubulointerstitial nephritis and related complications.

ABSTRACT

Introducción: El mielomeningocele (MMC) es una de las malformaciones congénitas más severas compatible con la vida. El 90% de los pacientes presenta vejiga neurogénica que debe ser evaluada y tratada precozmente. Objetivos: Describir la evaluación y tratamiento nefrourológico recibido por pacientes con MMC hasta el momento de la primera consulta en el Hospital Garrahan (periodo pre-ingreso). Describir la evaluación realizada y el tratamiento urológico implementado a partir del ingreso al hospital Garrahan (periodo post-ingreso). Evaluar la prevalencia de Enfermedad Renal Crónica (ERC). Población y Métodos: Se realizó un estudio con diseño clínico analítico, retrospectivo, longitudinal sobre pacientes con MMC de 1 mes a 18 años derivados al Hospital Garrahan para atención ambulatoria en los años 2011 y 2012. Resultados: Se incluyeron115 pacientes. Al momento de la derivación al hospital ("pre-ingreso") 7% de los pacientes habían logrado completar evaluación nefrourológica, (ecografía vesicorenal, urodinamia, Cistouretrografía, Centellograma renal y Creatininemia). Tratamiento: 33% vaciaban vejiga por CIL o vesicostomía y 21% recibían Oxibutinina. A partir del ingreso al seguimiento en el Garrahan 83% lograron completar la evaluación, y en función del resultado de la misma se indicó CIL en 87% y Oxibutinina en el 66% de los pacientes. La prevalencia de ERC al ingreso fue de 43%; la mayoría en estadio I. Conclusiones: La mayoría de los pacientes con MMC fueron derivados al hospital de tercer nivel con evaluaciones urológicas incompletas y sin el tratamiento adecuado de la vejiga neurogénica. El inicio del seguimiento interdisciplinario en un hospital de alta complejidad facilitó la realización de las evaluaciones necesarias y la implementación del tratamiento adecuado (AU)


Introduction: Myelomeningocele (MMC) is one of the most severe congenital malformations compatible with life. Of all the patients, 90% presents with a neurogenic bladder requiring early evaluation and treatment. Objectives: To describe the uronephrological evaluation and treatment received by patients with MMC up to the first consultation at Garrahan Hospital (pre-follow-up period). To describe the urological evaluation and treatment implemented from referral to Garrahan Hospital (follow-up period). To evaluate the prevalence of chronic kidney disease (CKD). Population and Methods: A retrospective, longitudinal study with a clinical, analytical design was conducted in patients with MMC between 1 months and 18 years of age referred to Garrahan Hospital for outpatient care in 2011 and 2012. Results: 115 patients were included. At the time of referral to the hospital ("pre-follow-up") 7% of the patients had undergone complete uronephrological evaluation (kidney-bladder ultrasonography, urodynamic studies, cystourethrography, renal scintigraphy, and creatininemia levels). Treatment: 33% emptied their bladder by CIC or vesicostomy and 21% received oxybutynin. From follow-up initiation at Garrahan Hospital, 83% underwent complete evaluation, and based on the results CIC was indicated in 87% and oxybutynin in 66% of the patients. On admission, prevalence of CKD was 43%; with stage I in the majority of the patients. Conclusions: The majority of the patients with MMC were referred to a third-level hospital with incomplete urological studies and without adequate treatment of the neurogenic bladder. Initiation of interdisciplinary follow-up at a tertiary hospital allowed for the necessary studies and implementation of adequate treatment (AU)

ABSTRACT

No presente estudo, foram analisados os efeitos do estanozolol, associado ou não à atividade física, sobre o hemograma, o peso ponderal, a ingestão líquida e sólida, a urinálise, a expressão do VEGF-A renal e o glicogênio hepático, além da histopatologia hepática e renal em ratos Wistar. Foram utilizados 32 ratos Wistar, machos, jovens, separados em quatro grupos: GC (grupo controle); GCE (grupo controle-exercício); GT (grupo tratamento-esteroide); GTE (grupo tratamento-esteroide-exercício). Os animais dos grupos GT e GTE (n=16) foram submetidos a injeções subcutâneas, cinco dias/semana, durante 30 dias, na concentração de 5mg/kg de estanozolol diluído em 1mL de óleo de gergelim, utilizado como veículo. A natação foi definida como exercício físico. Houve aumento no peso dos animais submetidos ao estanozolol e ao exercício a partir da terceira semana de uso e aumento da excreção urinária a partir da quinta semana; os demais parâmetros da urinálise foram semelhantes entre os grupos. O uso de estanozolol associado ou não à atividade física promoveu redução da expressão do VEGF-A nos rins e do glicogênio hepático, além de alterações histopatológicas nesses órgãos. Quanto à hematologia, houve uma diminuição dos leucócitos no GTE em relação aos grupos GT e GCE. Quanto aos linfócitos, houve um aumento no GT e uma diminuição no GTE, e, em relação ao número de plaquetas, houve diminuição no GTE quando comparado ao GT e ao GCE Assim, conclui-se que estanozolol na dose de 5,0mg/kg causa alterações renais e hepáticas em ratos Wistar, podendo levar à falência dos rins e do fígado.(AU)


The goal of this study was to determine the effect of stanozolol (ST) on kidney and liver of Wistar rats. Thirty-two male animals were divided into the following four groups: control group (CG); Control group-exercise (GCE); Group-steroid treatment (GT); Group treatment-steroid-exercise (GTE). Swimming was defined as exercise. The animals GT and GTE was submitted to subcutaneous injections, five days/week for 30 days, at a concentration of 5mg/kg ST diluted in 1mL/kg of sesame oil. The results showed an increase in weight gain in all animals submitted to ST and exercise from the 3rd week of use and increase in urinary excretion from the 5th week and the other urinalysis parameters were similar. The ST associated or not with physical activity reduced VEGF-A expression in the kidneys and hepatic glycogen, as well as histopathological changes in these organs. Regarding hematology, there was a decrease in leukocytes in the GTE. As for lymphocytes there was an increase in GT and a decrease in GTE, and in relation to the number of platelets, there was a decrease in GTE. In conclusion, the administration of stanozolol at 5.0mg/kg caused a structural change of kidney and liver in treated animals.(AU)

ABSTRACT

Abstract Introduction: It is unclear whether residual renal function (RRF) in dialysis patients can attenuate the metabolic impact of the long 68-hour interdialytic interval, in which water, acid, and electrolyte accumulation occurs. Objective: to evaluate serum electrolyte levels, water balance, and acid-base status in dialytic patients with and without RRF over the long interdialytic interval (LII). Methodology: this was a single-center, cross-sectional, and analytical study that compared patients with and without RRF, defined by diuresis above 200 mL in 24 hours. Patients were weighed and serum samples were collected for biochemical and gasometric analysis at the beginning and at the end of the LII. Results: 27 and 24 patients with and without RRF were evaluated, respectively. Patients without RRF had a higher increase in serum potassium during the LII (2.67 x 1.14 mEq/L, p < 0.001), reaching higher values at the end of the study (6.8 x 5.72 mEq/L, p < 0.001) and lower pH value at the beginning of the interval (7.40 x 7.43, p = 0.018). More patients with serum bicarbonate < 18 mEq/L (50 x 14.8%, p = 0.007) and mixed acid-base disorder (57.7 x 29.2%, p = 0.042), as well as greater interdialytic weight gain (14.67 x 8.87 mL/kg/h, p < 0.001) and lower natremia (137 x 139 mEq/L, p = 0.02) at the end of the interval. Calcemia and phosphatemia were not different between the groups. Conclusion: Patients with RRF had better control of serum potassium, sodium, acid-base status, and volemia throughout the LII.


Resumo Introdução: Não se sabe ao certo se a função renal residual (FRR) de pacientes dialíticos pode atenuar o impacto metabólico do maior intervalo interdialítico (MII) de 68 horas, no qual ocorre acúmulo de volume, ácidos e eletrólitos. Objetivo: Avaliar os níveis séricos de eletrólitos, balanço hídrico e status ácido-básico de pacientes dialíticos com e sem FRR ao longo do MII. Metodologia: Tratou-se de estudo unicêntrico, transversal e analítico, que comparou pacientes com e sem FRR, definida como diurese acima de 200 mL em 24 horas. Para tal, os pacientes foram pesados e submetidos à coleta de amostras séricas para análise bioquímica e gasométrica no início e fim do MII. Resultados: Foram avaliados 27 e 24 pacientes com e sem FRR, respectivamente. Pacientes sem FRR apresentaram maior aumento de potássio sérico durante o MII (2,67 x 1,14 mEq/L, p < 0,001) atingindo valores mais elevados no fim (6,8 x 5,72 mEq/L, p < 0,001); menor valor de pH no início do intervalo (7,40 x 7,43, p = 0,018), maior proporção de pacientes com bicarbonato sérico < 18 mEq/L (50 x 14,8 %, p = 0,007) e distúrbio ácido-básico misto (70,8 x 42,3 %, p = 0,042), além de maior ganho de peso interdialítico (14,67 x 8,87 mL/kg/h, p < 0,001) e menor natremia (137 x 139 mEq/L, p = 0,02) no fim do intervalo. A calcemia e fosfatemia não foram diferentes entre os grupos. Conclusão: Pacientes com FRR apresentaram melhor controle dos níveis séricos de potássio, sódio, status ácido-básico e da volemia ao longo do MII.

ABSTRACT

Introducción: La tasa de filtración glomerular se considera el mejor índice para evaluar la función renal, ya que su reducción aparece mucho antes que cualquier manifestación clínica derivada de la disfunción renal. Métodos: Se realizó un estudio observacional, descriptivo y transversal de 92 pacientes sin enfermedad renal y con esta, atendidos en el Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, de febrero a noviembre de 2017, a fin de evaluar las ecuaciones insuficiencia renal crónica-colaboración epidemiológica (CKD-EPI) para estimar el filtrado glomerular en adultos mayores. Resultados: Se halló menor promedio de filtrado con orina de 24 horas en el grupo sin nefropatía (64,8 mL/min) y mayor en el grupo de nefrópatas (25,8 mL/min) respecto a dichas ecuaciones. Aunque no hubo diferencias significativas en el filtrado según edad, sexo y peso corporal, en ambos grupos al emplear CKD-EPI, los valores mayores se obtuvieron con CKD-EPI cistatina C. Conclusiones: En los ancianos sin marcadores de daño renal la utilización de las fórmulas CKD-EPI con cistatina permite una mejor estimación de la función renal.


Introduction: The glomerular filtration rate is considered the best index to evaluate the renal function, since its reduction is evidenced much time before any clinical manifestation which derives from the renal failure. Methods: A descriptive, cross-sectional and observational study of 92 patients without and with renal disease, assisted in Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, from February to November, 2017, was carried out in order to estimate glomerular filtrate in older adults by means of the CKD-EPI equations. Results: Lower average filtrate with 24 hours urine was found in the group without nefropathy (64.8 mL/min) and it was higher in the kidney disease group (25.8 mL/min) regarding these equations. Although in both groups there were no significant differences in the filtrate according to age, sex and corporal weight, when using the equations CKD-EPI, the higher values were obtained with CKD-EPI cystatine C. Conclusions: The use of the formulas CKD-EPI with cystatine allows a better estimate of the renal function in aged patients without markers of renal damage.

ABSTRACT

Abstract Introduction: The management of kidney transplant recipients requires glomerular filtration rate (GFR) monitoring, which is an indicator of graft primary function and patient survival. Objective: To evaluate the performance of different creatinine or cystatin-based formulas in the estimation of glomerular filtration rate in Mexican patients receiving kidney transplantation. Method: 30 transplant recipients were included, in whom the glomerular filtration rate was measured by means of iothalamate, and was also calculated using seven equations based on cystatin or creatinine. Results: The formula with the best performance was the one proposed by the chronic kidney disease epidemiology collaboration (CKD-EPI), with a bias of −2.4 mL/min/1.73 m2: and an accuracy of 9.6; 96.7 % of patients were within 30 % of the measured GFR. The second best formula was the modification of diet in renal disease (MDRD) equation. Cystatin-based equations showed a poor performance. Conclusions: Our study suggests that, in Mexican patients receiving kidney transplantations, the best equations to estimate GFR are the CKD-EPI and MDRD equations.

ABSTRACT

ABSTRACT Purpose: To investigate the effect of robot assisted laparoscopic radical prostatectomy (RALP) and open retropubic radical prostatectomy (RRP) on early renal function in this study. Materials and Methods: Preoperative and postoperative urea, creatinine, Hb, eGFR values of patients who had undergone RALP and RRP with prostate cancer (PCa) diagnosis were recorded in our clinic. The percentages of change in these values are calculated. Preoperative and postoperative urea, creatinine, Hb and eGFR changes were compared with each other. Student-t test was used for intergroup comparison, and paired sample t test was used to compare changes between preoperative and postoperative values of the same group. Results: There were 160 and 93 patients in the RALP and RRP group, respectively. In the RALP group, postoperative urea and creatinine increased significantly compared to preoperative baseline values while eGFR was decreased (p = 0.0001, p = 0.001, p = 0.0001, respectively). Except for Hb in the RRP group, the changes in these values were statistically insignificant (p = 0.50, p = 0.75, p = 0.30, respectively). Conclusions: We should be more careful when we perform RALP in patients at risk of impaired renal function despite being a minimally invasive surgical method with superior visual characteristics.

ABSTRACT

In recent years, the concept of "augmented renal clearance" (ARC) has been proposed in the field of critical illness and is defined as enhanced renal clearance of drugs. ARC is considered when the creatinine clearance rate exceeds 130 mL/(min·1.73 m). An increasing number of evidence has shown that ARC is commonly seen in critically ill adults and children. In critically ill children, low drug concentration due to ARC may lead to treatment failure. Unfortunately, ARC is often neglected due to the lack of reliable tools to assess renal function in critically ill children. Therefore, with reference to the articles on ARC in critically ill children, this article reviews the concept of ARC, the pathogenesis of ARC, the influencing factors for ARC, the identification tools for ARC, and the influence of ARC on pharmacokinetics/pharmacodynamics of antibacterial agents and clinical outcome, in order to provide a reference for clinical medication.

ABSTRACT

BACKGROUND: The prevalence of chronic kidney disease is increasing worldwide. Several studies have suggested that obesity is associated with early renal dysfunction. However, little is known about the relationship between obesity phenotypes and early renal function decline. Therefore, this study aimed to identify the relationship between obesity phenotypes and early renal function decline in adults without hypertension, dyslipidemia, and diabetes. METHODS: We conducted a cross-sectional analysis of clinical and anthropometric data from 1,219 patients who underwent a routine health checkup in 2014. We excluded adults with cardiovascular disease, renal disease, diabetes, hypertension, dyslipidemia, or low glomerular filtration rate (<60 mL/min/1.73 m2). Renal function was determined according to the estimated glomerular filtration rate calculated using the Chronic Kidney Disease Epidemiology Collaboration creatinine-cystatin C equation. RESULTS: Age, sex, body mass index, waist circumference, triglyceride, low-density lipoprotein, and fasting glucose had an association with the estimated glomerular filtration rate. After adjusting for age, sex, smoking status, and alcohol intake, the odds ratios of the metabolically abnormal normal weight and metabolically abnormal obese phenotypes for the presence of low estimated glomerular filtration rates were 1.807 (95% confidence interval, 1.009–3.236) and 1.834 (95% confidence interval, 1.162–2.895), compared with the metabolically healthy normal weight phenotype. However, the metabolically healthy obese phenotype did not show a significant association with early renal function decline. CONCLUSION: In this cross-sectional study, we confirmed the association between the metabolically abnormal normal weight and metabolically abnormal obese phenotypes and early kidney function decline in adults without hypertension, dyslipidemia, and diabetes.

ABSTRACT

Abstract Purpose: To investigate the protective effects of salvianolic acid A (SAA) on renal damage in rats with chronic renal failure (CRF). Methods: The five-sixth nephrectomy model of CRF was successfully established in group CRF (10 rats) and group CRF+SAA (10 rats). Ten rats were selected as sham-operated group (group S), in which only the capsules of both kidneys were removed. The rats in group CRF+SAA were intragastrically administrated with 10 mg/kg SAA for 8 weeks. The blood urine nitrogen (BUN), urine creatinine (Ucr), creatinine clearance rate (Ccr), and serum uperoxide dismutase (SOD) and malondialdehyde (MDA) were tested. The expressions of transforming growth factor-β1 (TGF-β1), bone morphogenetic protein 7 (BMP-7) and Smad6 protein in renal tissue were determined. Results: After treatment, compared with group CRF, in group CRF+SAA the BUN, Scr, serum MDA and kidney/body weight ratio were decreased, the Ccr and serum SOD were increased, the TGF-β1 protein expression level in renal tissue was decreased, and the BMP-7 and Smad6 protein levels were increased (all P < 0.05). Conclusion: SAA can alleviate the renal damage in CRF rats through anti-oxidant stress, down-regulation of TGF-β1 signaling pathway and up-regulation of BMP-7/Smad6 signaling pathway.

ABSTRACT

ABSTRACT Objective The chia seed, an ancient pseudocereal, is rich in omega-3 fatty acids and polyphenols, and has been suggested to possess several health benefits. Although it has gained popularity among nutritionists, little is known about the systemic effects of chia and their interactions. Hence, hepatorenal indicators and plasma vitamin concentrations in chia-supplemented aluminum-exposed rats were investigated. Methods Wistar albino rats were either fed on a chia-rich- or standard-diet for 21 days and exposed to aluminum. Liver function tests (Alanine Aminotransferase, Aspartate Aminotransferase, Alkaline Phosphatase, Lactate Dehydrogenase), kidney function tests (Urea Nitrogen, Creatinine), and vitamin B12 and folic acid measurements were performed by using an automated analyzer. Results Aluminum exposure had no influence on renal function, as did chia supplementation. However, liver function was disturbed with the exposure to Aluminum and chia was of no use against it. Surprisingly, it was found that the animals fed on a chia-rich diet displayed higher concentrations of vitamin B12 which was not the case for folic acid. Conclusion It was deduced that a chia-rich diet has no effect on the renal function and is not able to reverse aluminum-induced hepatotoxicity; however, it may be of benefit against vitamin B12 insufficiency and thus, it may offer a novel treatment option which is particularly important in the vegan diet.


RESUMO Objetivo A semente de chia, um antigo pseudocereal, é rica em ácidos graxos ômega-3 e polifenóis e tem sido sugerida como tendo vários benefícios para a saúde. Embora tenha ganhado popularidade entre os nutricionistas, na verdade, pouco se sabe sobre os efeitos e interações sistêmicas da chia. Assim, investigamos os indicadores hepatorrenais e as concentrações plasmáticas de vitamina em ratos expostos ao alumínio suplementados com chia. Métodos Ratos albinos Wistar foram alimentados com dieta rica em chia ou padrão por 21 dias e expostos ao alumínio. Testes de função hepática (Alanina Aminotransferase, Aspartato Aminotransferase, Fosfatase Alcalina, Lactato Desidrogenase), testes de função renal (ácido úrico, Creatinina) e medições de vitamina B12 e ácido fólico realizada usando um analisador automático. Resultados A exposição ao alumínio não influenciou a função renal, assim como a suplementação de chia. No entanto, a função hepática foi perturbada com a exposição e a chia foi inútil contra ela. Surpreendentemente, descobrimos que os animais que se alimentavam de uma dieta rica em chia apresentavam concentrações mais elevadas de vitamina B12, o que não era o caso do ácido fólico. Conclusão Deduzimos que a dieta rica em chia não tem efeito sobre a função renal e não é capaz de reverter a hepatotoxicidade induzida pelo alumínio; no entanto, pode ser benéfico contra a insuficiência de vitamina B12 e, portanto, pode oferecer uma nova opção de tratamento que é particularmente importante na dieta vegana.

ABSTRACT

Objetivos: Describir los cambios en el agua corporal, masa magra, contenido de grasa, aclaramiento de creatinina y urea y características dietéticas de personas saludables en Lima-Perú. Material y métodos: Se incluyeron personas de sexo y edades entre 20 y 80 años, comparables con Índice Masa Corporal normal, autosuficientes, calidad de vida satisfactoria y sin enfermedad crónica. Se midieron los datos estructurales con Bioimpedancia. La función renal se determinó mediante la creatinina y urea en sangre y el aclaramiento de creatinina y de urea. Las características dietéticas se infirieron de la medición de urea, sodio y potasio en la misma muestra de orina. Resultados: Hubo diferencia significativa en: agua corporal, grasa, masa magra, creatinina (sérica y urinaria) y urea sérica entre sexos. La masa magra se relacionó directamente con el agua corporal (r=0,81; p=0,000 en hombres y r=0,465; p=0,000 en mujeres) e inversamente con la grasa. En el análisis de regresión lineal multivariado, únicamente la masa magra, grasa y agua corporal mostraron significancia estadística con la edad, pero los cambios de estas variables difirieron entre hombres y mujeres. La creatinina y urea sérica no cambiaron con la edad, pero sí el aclaramiento de ambas. El aclaramiento de urea tuvo regresión lineal en hombres y cúbica en las mujeres. Hubo correlación negativa entre edad e ingesta proteica en hombres (r=-0,594; p=0,006), sal sódica (r=-0,451; p=0,021) y potasio (r=-0,443; p=0,023) en mujeres. Conclusiones: La estructura corporal, filtración glomerular y hábitos dietéticos cambian con la edad en nuestra población normal, pero con características diferentes entre hombres y mujeres. (AU)


Objectives: To describe changes in body water, lean body mass, fatty content, creatinine and urea clearance and dietary habits of healthy persons in Lima. Methods: Persons of both sexes between 20 and 80 years with normal body mass index, self-sufficient, with satisfactory quality of life and without chronic renal disease were included in the study. Electric bio impedance was used to get body structural data. Renal function was measured with creatinine clearance, serum creatinine and urea. Dietary features were inferred from urea, sodium and potassium measurements from a urine sample. Results: A statistical significant difference in sexes was found for body water, fatty content, lean body mass, creatinine (in serum and urine) and urea. Lean body mass was directly correlated with body water (r=0.81; p=0.000 in males and r=0.465; p=0.000 in females) and inversely correlated with fatty content. The multivariate lineal regression analysis only found correlation of lean body mass, fatty content and body water with age, but changes in these variables differed between males and females. Serum urea and creatinine did not change with age, but the clearance of both of them did it. Urea clearance showed linear correlation in males but cubic in females. A negative correlation between age and protein intake was observed (r=-0.594; p=0.006), sodium salt (r=-0.451; p=0.021) and with potassium in females. Conclusions: Body structure, glomerular filtration and dietary habits change with age in our healthy population but with differences by sex. (AU)

ABSTRACT Introduction: Cystinuria is an autosomal recessive disorder due to intestinal and renal transport defects in cystine and dibasic amino acids, which result in recurrent urolithiasis and surgical interventions. This study aimed to assess the impact of surgical interventions on renal function by analyzing estimated glomerular filtration rates. Methods: Thirteen pediatric patients with cystinuria, who were followed-up in a single tertiary institution between 2004 and 2016, were included in the study. Medical records were reviewed to collect data on clinical presentation of patients, urine parameters, stone formation, medical treatment, surgical intervention, stone recurrence after surgical procedure, stone analysis, ultrasonography, 99m-technetium dimercaptosuccinic acid (99mTc-DMSA) radionuclide imaging results, and follow-up time. Creatinine clearances estimated by modified Schwartz (eGFR) formula before and after surgery were used to assess renal function and compared statistically. Results: Nine patients (69.2%) had renal scarring which were detected with 99mTc-DMSA radionuclide imaging. In ten patients (76.9%), open surgical intervention for stones were needed during follow-up. Significant difference was not detected between eGFR before and after surgical intervention (mean 92 versus 106, p = 0.36). Nine of the patients (69.2%) were stone free in the last ultrasonographic examination. Relapses of stone after surgery were seen in 66.6% of patients who underwent surgical intervention. Conclusions: Surgical interventions for urinary stones are commonly required in patients with cystinuria. Renal scarring is a prevalent finding in cystinuric patients. Surgical interventions have no negative impact on eGFR in patients with cystinuria according to the present study.


RESUMO Introdução: A cistinúria é um distúrbio autossômico recessivo causado por defeitos de transporte intestinal e renal da cistina e aminoácidos dibásicos que resultam em urolitíase recorrente e necessidade de intervenção cirúrgica. O presente estudo teve por objetivo avaliar o impacto das intervenções cirúrgicas sobre a função renal por meio da análise da taxa de filtração glomerular estimada. Métodos: Treze pacientes pediátricos com cistinúria acompanhados em uma instituição terciária entre 2004 e 2016 foram incluídos no estudo. Os prontuários médicos foram analisados e utilizados como fonte de dados sobre a apresentação clínica dos pacientes, parâmetros urinários, formação de cálculos, tratamento clínico, intervenção cirúrgica, recidiva de cálculos após procedimento cirúrgico, análise de cálculos, ultrassonografia, resultados de imagens com ácido dimercaptossuccínico marcado com tecnécio metaestável (99mTc-DMSA) e tempo de seguimento. A depuração de creatinina estimada pela fórmula modificada de Schwartz (TFGe) antes e após a cirurgia foi utilizada para avaliar e comparar estatisticamente os níveis de função renal. Resultados: Nove pacientes (69,2%) apresentaram cicatrizes renais detectadas por exame de imagem com 99mTc-DMSA. Dez pacientes (76,9%) necessitaram intervenção cirúrgica aberta por cálculo renal durante o seguimento. Não foram detectadas diferenças significativas entre os valores de TFGe anteriores e posteriores à intervenção cirúrgica (média de 92 vs. 106, p = 0,36). Nove pacientes (69,2%) não apresentaram cálculos no último exame ultrassonográfico. Recidivas de cálculos renais após cirurgia foram observadas em 66,6% dos pacientes submetidos a cirurgia. Conclusões: Intervenções cirúrgicas relativas a cálculos renais são frequentemente necessárias em pacientes com cistinúria. Cicatrizes renais são um achado prevalente em pacientes com cistinúria. De acordo com o presente estudo, cirurgia não afeta negativamente a TFGe de pacientes com cistinúria.

ABSTRACT

Abstract Purpose: To evaluate the toxicity of Erbitux as well as its biosimilar APZ001 antibody (APZ001) in pre-clinical animal models including mice, rabbits and cynomolgus monkeys. Methods: We performed analysis of normal behavior activity, autonomic and non-autonomic nervous functions, nervous-muscle functions, nervous excitability and sensorimotor functions on CD-1 mice. Subsequently, we studied that effects of APZ001 and Erbitux on respiratory system, cardiovascular system and kidney in Cynomolgus monkey models and performed local tolerance experiments on New Zealand rabbits. Results: The comparisons between APZ001 and Erbitux showed no significant differences in mice autonomic nervous system, nervous muscle functions, non-autonomic nervous functions, nervous excitability and sensorimotor functions between treated and untreated group (p>0.05). APZ001 and Erbitux showed negative effect on CD-1 mice in the present of pentobarbital sodium anesthesia (p>0.05). Single administrations of high, medium or low doses of APZ001 did not lead to monkey urine volume alterations (p>0.05). In human tissues, APZ001 and Erbitux showed positive signals in endocardium, lung type II alveolar epithelial cell and surrounding vessels, but showed negative results in kidney and liver tissues. No hemolysis phenomenon and serious side-effects in vessels and muscles were observed in rabbits when administrated with APZ001 and Erbitux respectively. Conclusion: The safety comparisons between APZ001 antibody and Erbitux showed that these two antibodies showed highly similarities in mice, rabbits and cynomolgus monkey animal models in consideration of pharmaceutical effects, indicating APZ001 might be a suitable substitute for Erbitux.

ABSTRACT

OBJETIVOS: Comparar a razão neutrófilos/linfócitos (RNL) e a razão plaquetas/linfócitos (RPL) entre pacientes com e sem diabetes mellitus tipo 2 e entre pacientes diabéticos com e sem disfunção renal. MÉTODOS: Estudo transversal retrospectivo realizado no Laboratório de Análises Clínicas do Hospital das Clínicas da Universidade Federal de Goiás entre janeiro e dezembro de 2016. Foram incluídos no estudo os dados dos pacientes com idade maior ou igual a 40 anos. Aqueles com glicemia casual ≥200mg/dL e/ou hemoglobina glicada ≥6,5% formaram o grupo diabético, e aqueles que não apresentavam esses critérios para diabetes formaram o grupo controle, sendo pareados por idade e sexo. O grupo diabético foi classificado em um grupo com dano renal e outro sem dano renal, de acordo com a microalbuminúria de 24 horas. Os cálculos para RNL e RPL foram realizados a partir do número absoluto de neutrófilos, linfócitos e plaquetas, e foram comparadas as medianas. RESULTADOS: Um total de 122 indivíduos foi incluído no estudo, entre os quais 52,5% tinham entre 40 e 64 anos de idade e 63,9% eram do sexo masculino. A mediana da RNL foi de 2,1 (mín. 0,8 -máx. 5,3) no grupo diabético e de 1,9 (mín. 0,6 -máx. 6,2) no grupo controle (p=0,16). A mediana da RPL foi de 120,5 (mín. 63,5 -máx. 206,6) no grupo diabético e de 119,7 (mín. 40,4 -máx. 215,1) no grupo controle (p=0,19). Considerando a faixa etária, não houve diferença das medianas de RNL e RPL entre o grupo de diabéticos e o grupo controle, entretanto a da RNL foi maior para indivíduos com 65 anos ou mais, independentemente de serem diabéticos (mediana 2,2; mín. 1,0 -máx. 3,8; p=0,0144) ou não (mediana 2,4; mín. 0,9 -máx. 3,6; p=0,0019). Dentre os participantes, 38 pacientes apresentavam dano renal, sendo 24 (63,1%) do grupo diabético e 14 (36,9%) do grupo controle. As medianas da RNL e da RPL foram semelhantes entre os pacientes diabéticos com dano renal, diabéticos sem dano renal e grupo controle. CONCLUSÕES: A RNL e a RPL foram semelhantes entre o grupo diabético e o grupo controle, assim como entre diabéticos com ou sem dano renal. A RNL foi maior para indivíduos com 65 anos ou mais, independentemente de serem diabéticos ou não.


AIMS: To compare the neutrophil/lymphocyte ratio (NLR) and the platelet/lymphocyte ratio (PLR) between patients with and without type 2 diabetes mellitus and between diabetic patients with and without renal dysfunction. METHODS: A cross-sectional retrospective study was performed at the Laboratory of Clinical Analyzes of the Hospital das Clínicas of the Federal University of Goiás between January and December 2016. Data from patients aged 40 years or older were included in the study. Those with a blood glucose ≥200mg / dL and/or glycated hemoglobin ≥6.5% formed the diabetic group, and those who did not present these criteria for diabetes formed the control group, being matched by age and sex. The diabetic group was classified in one group with renal damage and another without renal damage, according to the 24-hour microalbuminuria. Calculations for NLR and PLR were performed from the absolute number of neutrophils, lymphocytes and platelets, and the medians were compared. RESULTS: A total of 122 subjects were included in the study, among which 52.5% were between 40 and 64 years of age and 63.9% were male. The median NLR was 2.1 (min 0.8-max 5.3) in the diabetic group and 1.9 (min 0.6-max 6.2) in the control group (p=0.16). The median PLR was 120.5 (min 63.5-max 206.6) in the diabetic group and 119.7 (min 40.4-max 215.1) in the control group (p=0.19). Considering the age group, there was no difference in the median NLR or PLR among the diabetic group and the control group; however, the NLR was higher for individuals 65 years of age or older, regardless of whether they were diabetic (median 2.2, min 1.0-max 3.8, p=0.01) or not (median 2.4, min 0.9-max 3.6, p=0.001). Among the participants, 38 patients presented renal damage, 24 (63.1%) of the diabetic group and 14 (36.9%) of the control group. The median NLR and PLR were similar among diabetic patients with renal damage, diabetics without renal damage and control group. CONCLUSIONS: NLR and PLR were similar between the diabetic group and the control group, as well as among diabetics with or without renal damage. RNL was higher for individuals 65 years of age or older, regardless of whether they were diabetic or not.

ABSTRACT

La enfermedad renal en el paciente con drepanocitosis es una consecuencia de su complejo proceso fisiopatológico, por lo que es importante disponer de un grupo de parámetros de laboratorio que, junto a la evaluación clínica, permita determinar de forma precoz la presencia de esta complicación. La cistatina C ha demostrado ser uno de los parámetros que con mayor exactitud aporta evidencia temprana de daño renal en este grupo de pacientes y al mismo tiempo constituye un posible indicador de pronóstico de gran importancia(AU)


Renal disease in patients with sickle cell disease is a consequence of its complex pathophysiological process, so it is important to have a set of laboratory parameters that, together with the clinical evaluation, allow the early detection of this complication. Cystatin C has been shown to be one of the parameters that provides, with greater accuracy, early evidence of kidney damage in this group of patients and at the same time constitutes a possible indicator of prognosis of great importance(AU)

ABSTRACT

RESUMEN El virus de la hepatitis C es la principal infección trasmitida por los derivados de la sangre en los Estados Unidos, con 3.2 millones de individuos infectados. El alfa interferón inyectable ha sido históricamente la piedra angular en la terapia del virus de hepatitis C. Se revisaron las publicaciones los trabajos publicados en Medline, Scielo, PubMed, e Hinari, hasta comienzos del año 2016. Las principales palabras clave utilizadas fueron virus de la hepatitis C, hepatitis C crónica, Interferón, antivirales. Recientes adelantos han llevado a la disponibilidad de nuevos medicamentos antivirales, que con el desarrollo de nuevas terapias orales libres de interferón han convertido la terapia del virus de la hepatitis C más eficaz además de simplificar los regímenes del tratamiento. Aunque estos regímenes de tratamiento aún permanecen complicados, las nuevas recomendaciones y guías evolucionan rápidamente. El rápido desarrollo de nuevas terapias para la hepatitis C, han logrado métodos más eficaces con menos reacciones adversas que optimizan el tratamiento de estos enfermos (AU).


ABSTRACT The hepatitis C virus is the main infection transmitted by blood products in the United States, with 3.2 million of infected individuals. The injected alpha interferon has historically been the key stone in the therapy of the hepatitis C virus. The works published in Medline, Scielo, PubMed and Hinary until the beginning of 2016 were reviewed. The main used key words were HVC, cronic hepatitis C, interferon, antivirals. Recent advances have led to the availability on new antiviral drugs, developing new interferon-free oral therapies that make the therapy of hepatitis C virus more efficacious and make easier the treatment regimens. Although these treatment regimens are still complicated, the new recommendations and guidelines evolve quickly. The fast development of new therapies against hepatitis C has led to more efficacious methods with less adverse reactions, optimizing the treatment of these patients (AU).

ABSTRACT

ABSTRACT Objective This study aimed to evaluate the association between different renal biomarkers with D-Dimer levels in diabetes mellitus (DM1) patients group classified as: low D-Dimer levels (< 318 ng/mL), which included first and second D-Dimer tertiles, and high D-Dimer levels (≥ 318 ng/mL), which included third D-Dimer tertile. Materials and methods D-Dimer and cystatin C were measured by ELISA. Creatinine and urea were determined by enzymatic method. Estimated glomerular filtration rate (eGFR) was calculated using CKD-EPI equation. Albuminuria was assessed by immunoturbidimetry. Presence of renal disease was evaluated using each renal biomarker: creatinine, urea, cystatin C, eGFR and albuminuria. Bivariate logistic regression analysis was performed to assess which renal biomarkers are associated with high D-Dimer levels and odds ratio was calculated. After, multivariate logistic regression analysis was performed to assess which renal biomarkers are associated with high D-Dimer levels (after adjusting for sex and age) and odds ratio was calculated. Results Cystatin C presented a better association [OR of 9.8 (3.8-25.5)] with high D-Dimer levels than albuminuria, creatinine, eGFR and urea [OR of 5.3 (2.2-12.9), 8.4 (2.5-25.4), 9.1 (2.6-31.4) and 3.5 (1.4-8.4), respectively] after adjusting for sex and age. All biomarkers showed a good association with D-Dimer levels, and consequently, with hypercoagulability status, and cystatin C showed the best association among them. Conclusion Therefore, cystatin C might be useful to detect patients with incipient diabetic kidney disease that present an increased risk of cardiovascular disease, contributing to an early adoption of reno and cardioprotective therapies.

ABSTRACT

Background@#Vascular resistance and flow rate during hypothermic machine perfusion (HMP) of kidneys is correlated with graft function. We aimed to determine the effects of increasing HMP pressure versus maintaining the initial pressure on kidney transplantation outcomes.@*Methods@#We retrospectively reviewed the data of 76 primary transplantation patients who received HMP-preserved kidneys from 48 donors after cardiac death between September 1, 2013, and August 31, 2015. HMP pressure was increased from 30 to 40 mmHg (1 mmHg = 0.133 kPa) in kidneys with poor flow and/or vascular resistance (increased pressure [IP] group; 36 patients); otherwise, the initial pressure was maintained (constant pressure group; 40 patients). Finally, the clinical characteristics and transplantation outcomes in both groups were assessed.@*Results@#Delayed graft function (DGF) incidence, 1-year allograft, patient survival, kidney function recovery time, and serum creatinine level on day 30 were similar in both groups, with improved flow and resistance in the IP group. Among patients with DGF, kidney function recovery time and DGF duration were ameliorated in the IP group. Multivariate logistic regression analysis revealed that donor hypertension (odds ratio [OR]: 1.43, 95% confidence interval [CI]: 1.02-2.06, P = 0.035), donor terminal serum creatinine (OR: 1.27, 95% CI: 1.06-1.62, P = 0.023), warm ischemic time (OR: 3.45, 95% CI: 1.97-6.37, P = 0.002), and terminal resistance (OR: 3.12, 95% CI: 1.76-6.09, P = 0.012) were independent predictors of DGF. Cox proportional hazards analysis showed that terminal resistance (hazard ratio: 2.06, 95% CI: 1.32-5.16, P = 0.032) significantly affected graft survival.@*Conclusion@#Increased HMP pressure improves graft perfusion but does not affect DGF incidence or 1-year graft survival.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the renal protective effect of Tangshenkang Granule () in a rat model of diabetic nephropathy (DN).</p><p><b>METHODS</b>Forty male Sprague-Dawley rats were randomly divided into control, DN, Tangshenkang and benazepril groups. DN model was established in the rats of DN, Tangshenkang and benazepril groups. Tangshenkang Granule solution and benazepril hydrochloride solution were intragastrically administered daily to the rats in the Tangshenkang and benazepril groups for 8 weeks, respectively. Urinary albumin and creatinine were detected. The albumin/creatinine (ACR) was calculated in addition to 24 h urinary protein (24-h UPr), serum creatinine (Scr), blood urea nitrogen (BUN), total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and creatinine clearance rate (Ccr). Right kidneys were harvested for pathological observation using periodic acid-silver methenamine-Masson staining. The average glomerular diameter (DG), average glomerular (AG) and mesangial areas (AM) were measured. The thickness of glomerular basement membrane (TGBM) was detected using transmission electron microscope.</p><p><b>RESULTS</b>Compared with rats in the control group, rats in the DN group showed significantly decreased body weight, increased hypertrophy index, 24-h urinary volume, 24-h UPr, ACR, Scr, BUN, Ccr, blood lipids as well as renal pathological indices including DG, AG, AM, AM/AG and TGBM (P <0.05). Compared with the DN group, the weights of rats in the Tangshenkang and benazepril groups were significantly increased, and the renal hypertrophy indices were significantly decreased (P <0.05). The 24-h urinary volumes, ACR, 24-h UPr, Scr, BUN, Ccr, LDL, DG, AG, AM and TGBM were obviously decreased (P <0.05). Compared with the benazepril group, the Tangshenkang group showed significantly decreased levels of ACR, 24-h UPr, AG and AM (P <0.05).</p><p><b>CONCLUSIONS</b>Tangshenkang Granule decreased the urinary protein, attenuated the high glomerular filtration rate and improved lipid metabolism in DN rats, and prevented further injury induced by diabetic nephropathy.</p>
