The association of markers of oxidative-inflammatory status with malnutrition in hemodialysis patients with serum ferritin lower than 500 ng/mL
INTRODUCTION: Enhanced inflammatory-oxidative status is well established in chronic kidney disease. OBJECTIVE: The objective of this study was to evaluate the oxidative- inflammatory status and iron indices in patients undergoing maintenance hemodialysis (HD) with serum ferritin lower than 500ng/mL,...

OBJECTIVE: The objective of this study was to evaluate the oxidative- inflammatory status and iron indices in patients undergoing maintenance hemodialysis (HD) with serum ferritin lower than 500ng/mL, and to correlate them with nutritional status. METHOD: In a cross-sectional survey 35 HD patients (23 with normal nutritional status, 12 with Protein-Energy-Wasting syndrome, PEW), and healthy volunteers (n = 35) were studied. Serum concentration of iron, ferritin, transferrin saturation, malondialdehyde (MDA), protein carbonyl (PC), high-sensitive serum C -reactive protein (hs-CRP) and blood counts were determined. The nutritional status was determined by anthropometric and biochemical criteria. RESULTS: HD patients showed low values of hemoglobin and higher values of ferritin, MDA and PC when compared with healthy volunteers. HD subjects with PEW had higher values of PC and hs-PCR as compared to HD patients with normal nutritional status. A multiple logistic regression analysis showed that the independent variables PC (Wald Statistic 4.25, p = 0.039) and hs-CRP (Wald Statistic 4.83, p = 0.028) where related with the patients' nutritional condition. CONCLUSION: In HD patients with serum ferritin below 500 ng/mL was observed one association of the markers of oxidative stress and inflammation with poor nutritional status independently of serum ferritin, gender and age. INTRODUÇÃO: Na doença renal crônica, a presença de um estado inflamatório-oxidativo aumentado está bem estabelecida. OBJETIVO: O objetivo do presente estudo foi avaliar o estado oxidativo e inflamatório e o perfil do ferro em pacientes submetidos à hemodiálise crônica de manutenção, com ferritina menor do que 500 ng/mL, e correlacioná-los com o estado nutricional. MÉTODO: Em estudo transversal, em 35 pacientes sob hemodiálise (23 com estado nutricional normal, 12 com desnutrição energético-proteica (DEP) e 35 voluntários sadios foram determinados os índices hematimétricos e as concentrações séricas do ferro, da ferritina e avaliada a saturação de transferrina. O estado oxidativo foi determinado por meio das concentrações séricas do malondialdeído (MDA) e da proteína carbonil (PC). Nos indivíduos sob hemodiálise o estado inflamatório foi avaliado por meio da proteína C reativa ultrassensível determinada no soro (hs-PCR). O estado nutricional foi determinado por critérios antropométricos e bioquímicos. RESULTADOS: Os pacientes da hemodiálise mostraram anemia e um estado oxidativo mais elevado do que os voluntários sadios. Os pacientes hemodialisados com DPE mostraram ferritina e um estado inflamatório-oxidativo mais elevado se comparados aos com boa condição nutricional. Em análise de regressão logística múltipla, os níveis séricos de PC e hs-CRP foram correlacionados com o estado nutricional. PC (Estatística Wald 4.25, p = 0,039), CRP (Estatística Wald 4.83, p = 0,028). CONCLUSÃO: Em indivíduos submetidos à hemodiálise, com ferritina menor do que 500 ng/mL. Observou-se uma associação entre os marcadores de estresse oxidativo e inflamatório com o estado nutricional, independentemente da idade, gênero e dos índices do ferro. 2017-12-07T05:02:34Z 2017-12-07T05:02:34Z 2013 Artigo J.
