The administration of aluminium in rats with chronic renal failure resulted in reductions in serum PTH and PTH mRNA. Thus far, previous studies had demonstrated that aluminium suppressed PTH release. The present findings suggest that PTH synthesis is also reduced.
In a retrospective study, we identified 55 elderly patients with acute renal failure (ARF) admitted to our hospital during an 8-year period from 1985 to 1993. Information about the etiology, complications, laboratory data, and treatment course were obtained from the clinical history. Of the 200 patients with ARF admitted to the hospital during this period, 28% were patients more than 60 years old (41 male and 14 female) with an average age of 68.5 +/- 7 years. The main causes of ARF were sepsis, volume depletion, low cardiac output, arterial hypotension, nephrotoxicity by antibiotics, and obstructive uropathy. The global mortality of elderly patients with ARF was 53%. The mortality rate of the different types of the ARF were: prerenal 35%, intrinsic 64% (oliguric 76%, nonoliguric 50%), and postrenal 40%. Mortality as a result of sepsis occurred in 18 patients (62%), by cardiovascular disease in 4 patients (13%), by acute respiratory failure in 2 patients (7%), and by other causes in 5 patients (18%). In the cases of sepsis, Pseudomonas was detected in 7 cases (39%), Escherichia coli in 2 cases (11%), Gram-negative nonspecific in 3 cases (17%), Klebsiella in 1 case (5%), and in 5 cases (16%), the hemoculture was negative. The patient survival rate was 47% (26 of 55 patients). Of these patients, 19 recovered their normal renal function (73%), but 7 patients remained with renal failure (27%). In conclusion, the global mortality in the elderly patients without considering the types of ARF was 53%. The oliguric form had the highest mortality rate with 76%. The main causes for mortality were sepsis with 62%, cardiovascular disease with 13%, and other causes 18%.
Paraguay is a landlocked country located in South America with a total population of 5,884,491. Most of the population (95%) is mestizo, a mixture of Spanish and American/Indian races. The total number of indigenous people in the country has increased from 38,703 in 1981 to 85,674 in 2002. The gross domestic product per capita was US $932.00 annually per person in the year 2002. Between 1992 and 1997, there were 380 patients on chronic dialysis in Paraguay and 75 patients received renal transplants, mostly living-related. The prevalence of renal replacement therapy was 87 patients per million, and the incidence of renal disease continues to rise. Seventy percent of cases of ESRD are of unknown etiology and 15% have diabetes-related renal disease. Only citizens covered by the employee's national health insurance have complete coverage for dialysis and transplantation. The remainder of the population has to apply to public hospitals when the need for hemodialysis arises. At such hospitals, they can receive hemodialysis coverage from the National Institute of Nephrology or from other medical foundations to obtain entrance to these programs. They must otherwise use their own resources to pay for treatment. Seventy percent of patients on chronic dialysis turn to public hospitals for treatment. Hospital hemodialysis is the method most widely used. Home dialysis is rarely performed and there are very few programs for ambulatory peritoneal dialysis. Thus, a large number of patients are not able to enter chronic dialysis programs. In a recent survey of 4655 ill children registered, the distribution of main renal disease was acute glomerulonephritis in 42 cases (9 per 1000), nephrotic syndrome in 40 cases (8.5 per 1000), systemic lupus erythematosis in 28 cases (6 per 1000), and hematuria alone in 11 cases (2.3 per 1000). In ambulatory pediatric practice, urinary tract infection is the leading reason for seeking medical advice. Two thirds of such cases are associated with urinary tract anomalies. Children with ESRD are able to enter hemodialysis programs, but there are not sufficient resources to transplant them. Over 60% of the children with ESRD are hospitalized with terminal renal failure; malformations of the urinary tract are the usual cause. One study of 9880 adults aged 18 to 74 years reported that 39.1% of the women and 26.8% of the men examined were found to have hypertension. Almost half who were found to have raised blood pressure in this study were not previously known to have hypertension. In another cross-sectional study of the urban and suburban mestizo population of Asuncion among patients between 20 and 74 years of age, the overall prevalence of diabetes mellitus was 6.5%, impaired glucose tolerance 13.5%, hypertension 17%, and obesity 31.6%. Extrapolating from this data, we can assume that 178,000 patients with hypertension in Paraguay need medical treatment. To face the problem of growing numbers of patients with end-stage renal failure, it is necessary to carry out basic epidemiologic research to detect...
RESUMEN INTRODUCCIÓN:Se han atribuido muchos efectos beneficiosos a la moringa oleífera en varias publicaciones siendo de gran interés su efecto hipoglicemiante por disminución de la absorción intestinal de glucosa, aunque no está definido si su eficacia hipoglicemiante sería igual o mayor a algún hipoglicemiante oral conocido. El objetivo del presente estudio fue determinar el efecto agudo de moringa oleífera en hiperglucemia inducida por dexametasona en ratas Wistar hembras, así como comparar su efecto hipoglicemiante con la metformina. MATERIALES Y MÉTODOS: Estudio experimental, tres grupos de cinco ratas Wistar hembras, con peso de 188 ± 11 gramos. Se realizó la medición de la glucemia basal con glucómetro, después de 12 horas de ayuno, la inicial al principio del experimento, luego fueron tratadas con dexametasona 10 mg/kg/día, subcutánea, durante 10 días y se tomó la glicemia post dexametasona . Los días 11 a 14, recibieron el grupo 1 (suero fisiológico), grupo 2 (moringa oleífera 300 mg/kg/día) y grupo 3 (metformina 14,28 mg/kp/día), por sonda oro gástrica, el día 15 se tomó la glucemia post tratamiento. Se analizó el promedio, desviación estándar y la correlación mediante la prueba la prueba T de Student, se consideró P < a 0,05 como significativa. RESULTADOS: Grupo 1 (control): glucemia inicial (117 ± 21 mg/dl), post-dexametasona (445 ± 260 mg/dl) y post tratamiento (222 ± 5 mg/dL), Grupo 2 (moringa oleífera): glucemia inicial (95±27 mg/dl), post dexametasona (413 ± 184 mg/dl) y post tratamiento (102 ± 18 mg/dl) y del Grupo 3 (metformina): glucemia inicial (110 ± 5 mg/dl), post-dexametasona (470 ± 146 mg/dl) y post tratamiento (88 ± 11 mg/dL). La glucemia pos tratamiento mostró diferencias entre el grupo 1 y 2 (p < 0,0001), entre el grupo 1 y 3 (p < 0,0001) no hallándose diferencias entre los grupos moringa oleífera y metformina (p = 0,1). DISCUSIÓN: la moringa oleífera disminuye en forma aguda la hiperglucemia inducida por dexametasona en ratas hembras Wistar, con la misma eficacia que la metformina Palabras clave: moringa oleífera, hiperglicemia, ratas Wistar, mefformina. ABSTRACTSanta Cruz F et al Efecto agudo de moringa oleífera sobre la hiperglucemia inducida por ... An. Fac. Cienc. Méd. (Asunción) / Vol. 48 -Nº 1, 2015 42INTRODUCTION: It has been attributed many beneficial effects of moringa oleífera in various publications to be of great interest for its hypoglycemic effect due to decreased intestinal absorption of glucose; although it is not defined if his hypoglycemic efficacy would be equal to or greater than any known oral hypoglycemic agent. The objective of this study was to determine the acute effect of moringa oleífera on hyperclycemia induced by dexamethasone in female Wistar rats and compare its hypoglycemic effect with metformin. MATERIALS AND METHODS: Experimental study, wiht 3 groups of 5 female Wistar rats, weighing 188 ± 11 grams. Measuring the basal blood glucose meter was performed after 12 hours of fasting, the initial glycemia at the beginning of the experiment and were then ...
ResumenEste consenso fue ideado por el Director del Programa Nacional de Prevención Cardiovascular del M.S P. y B.S. (Paraguay) a raíz de que se necesitaba un documento actualizado que sirva como guía a los profesionales de la salud de todos los niveles de atención incluyendo a las diferentes especialidades, que tratan la hipertensión arterial y sus complicaciones agudas y crónicas. A través del convenio entre el Programa Nacional de Prevención Cardiovascular y la Sociedad Paraguaya de Cardiología de realizar actualizaciones de las Guías o documentos para difusión de manejo de patologías cardiovasculares y factores de riesgo asociados, se ha decidido elaborar y lanzar este material, que será utilizado como guía oficial en todo el territorio nacional.Con mesas de trabajo de varios días y la colaboración de representantes de sociedades científicas afines y asesores internacionales se ha logrado esta guía. Se presentan recomendaciones para facilitar el manejo de los pacientes con hipertensión arterial y sus complicaciones, con el propósito de disminuir la morbimortalidad cardiovascular. Han sido elaboradas según las evidencias científicas y conocimiento de expertos, con un enfoque práctico y sencillo. ConsensoTodos los participantes aprobaron las decisiones finales. Los autores reconocen que la publicación y difusión de directrices serán siempre una guía práctica y que permitirá a los médicos ampliar los conocimientos con las recomendaciones propuestas, detectar precozmente el daño de órganos blancos y mejorar la calidad de vida de los pacientes hipertensos.Palabras claves: enfermedades cardiovasculares-epidemiología, hipertensión-diagnóstico, hipertensión inducida en el embarazo, hipertensión renal, diabetes mellitus tipo 2, insuficiencia cardiaca, antihipertensivos, estilo de vida, presión arterial, guía.La hipertensión arterial es el principal factor de riesgo cardiovascular, que está asociado a las principales causas de mortalidad cardiovascular a nivel mundial. En el Paraguay es un serio problema de salud pública. Según el primer trabajo de investigación epidemiológica sobre hipertensión arterial en Paraguay a nivel nacional, realizado en el año 1993 al 1995, donde se analizaron también los factores de riesgo de la misma, se detectó un 42% de hipertensos, en edades de 18 a 74 años de edad, afectando más a mujeres que varones. El 50% de todos los hipertensos estaban comprendidos entre 30 y 59 años de edad. La prevalencia fue más alta en el área metropolitana, por la mayor densidad poblacional, pero se encontró el problema en todo el país.En varios estudios realizados posteriormente, hasta la fecha, el problema de hipertensión arterial en el país, sigue siendo muy serio, a pesar de los programas de control de la enfermedad que se iniciaron desde 1995 en el Ministerio de Salud Pública y Bienestar Social, a los que se agregaron programas de control desde otras instituciones como la Sociedad Paraguaya de Cardiología y la Sociedad Paraguaya de Hipertensión Arterial. This consensus was conceived by the Director of th...
