Previous issue date: 2015-03-26 / Conselho Nacional de Pesquisa e Desenvolvimento Cient?fico e Tecnol?gico - CNPq / Chronic kidney disease is a progressive condition, with no healing prospect, yet extended upholding under adequate monitoring and treatment. Approximately 100,000 patients currently undergo dialysis therapy - ninety percent on hemodialysis. Mortality ratio varies between 15 to 20%, being cardiovascular events mainly responsible. Among mental ailments thwarting kidney disease patients, depression is the most frequently associated co-morbidity, and linked to increased mortality and morbidity rates. In patients undergoing hemodialysis, malnourishment may relate with depressive symptoms, besides inflammation and cardiovascular diseases. Life style changes induced by end-stage renal disease impose a number of limitations that end up affecting the quality of life. Protein depletion is commonly observed in patients submitted to hemodialysis, and is associated with higher mortality. Strangely enough, it may be accompanied by weight gain and central fat accumulation. The role of adipocytokines in chronic kidney disease has recently drawn attention: association of serum chemerin to metabolic syndrome indicators, inflammation and obesity has been suggested. The aim of this study was to longitudinally evaluate nutritional status, presence of depressive symptoms, quality of life and mortality of hemodialysis patients, in a cohort study at the S?o Lucas Hospital /PUCRS, Porto Alegre, Brazil. Stable patients, undergoing hemodialysis for at least three months, were enrolled and evaluated at twelve month-intervals, thereafter. Participants were assessed for: depressive symptoms using the Beck Depression Inventory and for quality of life perception by the WHOQOL-bref questionnaire. Anthropometric data: weight, height, waist circumference; blood collection: for biochemical determinations, high-sensitivity C-reactive protein, chemerin; body composition analysis by direct segmental multi frequency bioimpedance, were obtained at a mid week dialysis session. One hundred and five participants were included. Patients classified as having standard percentage of body fat predominated, although more than half of the enrolled participants presented with excess body fat. There was no significant difference in the rate of depressive symptoms or in the quality of life between groups, classified by nutritional status. The cause more often associated with the outcome death by any cause was cardiovascular event, followed by infection. Lean body mass had a protective effect on survival. Chemerin may have an anti-inflammatory effect, being associated with increased body fat percentage and augmented waist circumference, on end-stage renal disease patients. / A doen?a renal cr?nica ? uma doen?a progressiva, que n?o contempla expectativa de cura, mas o prolongamento da cronicidade, com acompanhamento e tratamento adequados. Quase 100.000 pacientes s?o submetidos a tratamento dial?tico, 90% em hemodi?lise. A taxa de mortalidade bruta varia entre 15 a 20%, sendo eventos cardiovasculares os principais respons?veis. Dentre os problemas mentais que acometem pacientes com doen?a renal, depress?o ? a comorbidade mais frequente, associada a aumento das taxas de morbimortalidade. Desnutri??o pode se relacionar com sintomas de depress?o, assim como inflama??o e doen?a cardiovascular, em pacientes tratados por hemodi?lise. As mudan?as de estilo de vida induzidas pela doen?a renal cr?nica terminal causam in?meras limita??es que afetam a qualidade de vida. Deple??o proteica em pacientes submetidos a hemodi?lise ? frequentemente observada, e se associa com elevada mortalidade. Curiosamente, pode se acompanhar por excesso de peso e ac?mulo de gordura central. O papel das adipocitocinas na doen?a renal cr?nica tem despertado interesse: associa??o de quemerina s?rica com indicadores de s?ndrome metab?lica, inflama??o e obesidade foram sugeridas. O objetivo do presente estudo ? correlacionar estado nutricional, sintomas de depress?o, qualidade de vida e mortalidade em hemodi?lise. Foi realizado estudo prospectivo de coorte com pacientes em hemodi?lise no Hospital S?o Lucas/PUCRS, Porto Alegre, Brasil. Os pacientes estavam h? tr?s ou mais meses em hemodi?lise, clinicamente est?veis. A cada doze meses, pacientes inclu?dos no estudo foram reavaliados para: sintomas de depress?o ? por question?rio Beck de depress?o; percep??o da qualidade de vida ? pelo question?rio WHOQOL-bref; medidas antropom?tricas ? peso, altura, circunfer?ncia da cintura; coleta de sangue - para dosagens de par?metros bioqu?micos, prote?na C-reativa e quemerina; an?lise da composi??o corporal ? por bioimped?ncia segmentar de multi-frequ?ncias. Foram inclu?dos 105 pacientes. Houve um predom?nio de pacientes com percentagem de gordura padr?o, mas mais da metade dos pacientes tinha excesso de gordura corporal. N?o houve diferen?a na presen?a de sintomas depressivos e na qualidade de vida entre os grupos classificados por estado nutricional. A principal causa associada ao desfecho ?bito por qualquer causa foi evento cardiovascular, seguida por infec??o. A massa muscular apresentou efeito protetor para sobrevida. Quemerina s?rica aparentemente tem a??o anti-inflamat?ria em pacientes com doen?a renal cr?nica terminal, e est? associada a percentual de gordura corporal e a circunfer?ncia da cintura aumentada.
