Resumo
A Doença Renal Crônica (DRC) é caracterizada pela perda lenta, progressiva e irreversível da função renal. A DRC pode levar o organismo a desenvolver outras doenças, como a desnutrição e dislipidemias com risco elevado para as doenças cardiovasculares (DCV). A homocisteína é um aminoácido sulfurado não formador de proteína, produzido pelo organismo através do metabolismo da metionina, proveniente tanto de fontes dietéticas quanto de catabolismo protéico endógeno nas vias de desmetilação e de transulfuração. O folato é essencial para a via metabólica de remetilação. A suplementação de ácido fólico reduz os riscos de doenças vasculares, por redução da homocisteína. O objetivo do estudo foi verificar os efeitos da suplementação de ácido fólico nas concentrações de homocisteína plasmática em pacientes portadores de DRC em tratamento conservador e em hemodiálise. Foram sujeitos deste experimento 27 pacientes portadores em tratamento conservador (DRC-C), sendo 44,44% do sexo masculino e 55,56% do sexo feminino e 24 pacientes renais crônicos em hemodiálise (DRC-H), sendo 16 (66,67%) do sexo masculino e 8 (33,33%) do sexo feminino. Os pacientes foram pesados e medidos para a avaliação de IMC. A circunferência de braço (CB) e a prega cutânea tricipital (PCT), foram usadas para avaliação da massa magra e massa adiposa junto com a circunferência da cintura (CC). Todos os pacientes receberam 5 mg de ácido fólico via oral. Para a avaliação dos efeitos da suplementação de ácido fólico ao longo do tempo, foram feitos exames bioquímicos em três momentos distintos: 1º (1 = sem suplementação); 2º (2 = após três meses de suplementação) e 3º (3 = após seis meses de suplementação). A albumina foi avaliada por método calorimétrico, perfil lipídico por método enzimático, homocisteína por imunofluorecência polarizada e PCR por...
Chronic Kidney Disease (CKD) is characterized by loss slow, progressive and irreversible renal function. CKD can lead the body to develop other diseases such as malnutrition and dyslipidemia at high risk for cardiovascular disease (CVD). Homocysteine is a sulfur amino acid not forming protein produced by the body through metabolism of methionine, from both dietary sources and endogenous protein catabolism in demethylation and pathways of transsulfuration. Folate is essential for the metabolic pathway of remethylation. The folic acid supplementation reduces the risk of vascular disease by reducing homocysteine. The aim of this study was to investigate the effects of folic acid supplementation on plasma homocysteine concentrations in patients with CKD on hemodialysis and conservative treatment. 27 patients, patients receiving conservative treatment (CKD-C) were subjected to this experiment, male 44.44% and 55.56% female and 24 patients on hemodialysis (CRF-H), 16 (66.67%) were male and 08 (33.33%) were female. The patients were weighed and measured to assess BMI. The arm circumference (MUAC) and triceps skinfold thickness (TSF), were used to assess lean body mass along with fat mass and waist circumference (WC). All patients received 5 mg oral folic acid. To evaluate the effects of folic acid supplementation over time were performed biochemical tests at three different times: 1º (1 = no supplement), 2º (2 = after three months of supplementation) and 3 º(after six months supplementation) . Albumin was measured by calorimetric method, lipid by an enzymatic method for homocysteine by PCR and immunofluorescence were polarized absorbance. In relation to BMI 44.44% of patients DRC-C are eutrophic. Patients DRC-H 54.17% had normal weight. The diagnosis of normality and CMB to PCT was 55.56% and 48.15% respectively. DRC-H group in 58.33% had values above the waist fitting, since the patients ... (Complete abstract click electronic access below)
