Salud renal y salud en la mujer: Una oportunidad para mejorar las condiciones de las generaciones actuales y futuras

y el impacto de la enfermedad en el paciente y sus familias puede ser devastador. En el 2018 el Día Mundial del Riñón y el Día Internacional de la Mujer coinciden, ofreciéndonos una oportunidad para demostrar el impacto que tiene la salud de la mujer, específicamente su salud renal, en la comunidad y en las generaciones futuras, es importante fomentar el conocimiento sobre aspectos específicos de la enfermedad renal en la mujer y poder aplicarlos de forma extensiva. Las mujeres y niñas representan aproximadamente el 50 % de la población mundial, siendo integrantes fundamentales de la sociedad y de sus familias. Las diferencias de género persisten alrededor del mundo, afectando su acceso a la educación, cuidados de salud y su inclusión en estudios clínicos. Actualmente, el embarazo en la mujer es una etapa única que ofrece la oportunidad de diagnosticar la enfermedad renal, donde las enfermedades renales agudas y crónicas pueden manifestarse, lo cual podría impactar en la salud renal de las generaciones futuras. Existen varias enfermedades autoinmunes y algunos otros factores que afectan más comúnmente a la mujer, con serias consecuencias durante el embarazo para la madre y para el feto. Las mujeres en diálisis en comparación con los hombres tienen complicaciones diferentes; además son más comúnmente donadoras que receptoras del trasplante renal. En esta editorial, nos enfocamos en qué hacemos y en qué no conocemos sobre la mujer, la salud y enfermedad renal, y qué podemos aprender para mejorar sus condiciones en todo el mund

Low-protein diets for chronic kidney disease patients: The Italian experience

open20Nutritional treatment has always represented a major feature of CKD management. Over the decades, the use of nutritional treatment in CKD patients has been marked by several goals. The first of these include the attainment of metabolic and fluid control together with the prevention and correction of signs, symptoms and complications of advanced CKD. The aim of this first stage is the prevention of malnutrition and a delay in the commencement of dialysis. Subsequently, nutritional manipulations have also been applied in association with other therapeutic interventions in an attempt to control several cardiovascular risk factors associated with CKD and to improve the patient's overall outcome. Over time and in reference to multiple aims, the modalities of nutritional treatment have been focused not only on protein intake but also on other nutrients.openBellizzi, Vincenzo; Cupisti, Adamasco; Locatelli, Francesco; Bolasco, Piergiorgio; Brunori, Giuliano; Cancarini, Giovanni; Caria, Stefania; De Nicola, Luca; Di Iorio, Biagio R; Di Micco, Lucia; Fiaccadori, Enrico; Garibotto, Giacomo; Mandreoli, Marcora; Minutolo, Roberto; Oldrizzi, Lamberto; Piccoli, Giorgina B; Quintaliani, Giuseppe; Santoro, Domenico; Torraca, Serena; Viola, Battista FBellizzi, Vincenzo; Cupisti, Adamasco; Locatelli, Francesco; Bolasco, Piergiorgio; Brunori, Giuliano; Cancarini, Giovanni; Caria, Stefania; De Nicola, Luca; Di Iorio, Biagio R; Di Micco, Lucia; Fiaccadori, Enrico; Garibotto, Giacomo; Mandreoli, Marcora; Minutolo, Roberto; Oldrizzi, Lamberto; Piccoli, Giorgina B; Quintaliani, Giuseppe; Santoro, Domenico; Torraca, Serena; Viola, Battista F

Chronic kidney disease, severe arterial and arteriolar sclerosis and kidney neoplasia: on the spectrum of kidney involvement in MELAS syndrome

<p>Abstract</p> <p>Background</p> <p>MELAS syndrome (MIM ID#540000), an acronym for Mitochondrial Encephalopathy, Lactic Acidosis and Stroke-like episodes, is a genetically heterogeneous mitochondrial disorder with protean manifestations and occasional kidney involvement. Interest in the latter is rising due to the identification of cases with predominant kidney involvement and to the hypothesis of a link between mitochondrial DNA and kidney neoplasia.</p> <p>Case presentation</p> <p>We report the case of a 41-year-old male with full blown MELAS syndrome, with lactic acidosis and neurological impairment, affected by the "classic" 3243A > G mutation of mitochondrial DNA, with kidney cancer. After unilateral nephrectomy, he rapidly developed severe kidney functional impairment, with nephrotic proteinuria. Analysis of the kidney tissue at a distance from the two tumor lesions, sampled at the time of nephrectomy was performed in the context of normal blood pressure, recent onset of diabetes and before the appearance of proteinuria. The morphological examination revealed a widespread interstitial fibrosis with dense inflammatory infiltrate and tubular atrophy, mostly with thyroidization pattern. Vascular lesions were prominent: large vessels displayed marked intimal fibrosis and arterioles had hyaline deposits typical of hyaline arteriolosclerosis. These severe vascular lesions explained the different glomerular alterations including ischemic and obsolescent glomeruli, as is commonly observed in the so-called "benign" arteriolonephrosclerosis. Some rare glomeruli showed focal segmental glomerulosclerosis; as the patient subsequently developed nephrotic syndrome, these lesions suggest that silent ischemic changes may result in the development of focal segmental glomerulosclerosis secondary to nephron loss.</p> <p>Conclusions</p> <p>Nephron loss may trigger glomerular sclerosis, at least in some cases of MELAS-related nephropathy. Thus the incidence of kidney disease in the "survivors" of MELAS syndrome may increase as the support therapy of these patients improves.</p
