Abstract

ABSTRACT BACKGROUND Patients that underwent Percutaneous Endoscopic Gastrostomy (PEG) present with protein-energy malnutrition. Trace elements are required in small quantities and Chromium (Cr) displays a major role in the metabolism. OBJECTIVE This study aims to evaluate Cr levels and its relationship with serum proteins, BMI and underlying diseases during the first 3 months of PEG feeding. METHODS Prospective observational study during 3-months, when PEG was performed (T0), after 4 (T1), and 12 weeks (T3). Initial evaluation included: age, gender, underlying disease, NRS-2002, BMI, serum albumin, transferrin and Cr concentration. At T1 and T3 a blood sample was collected for Cr, albumin and transferrin. A Graphite Furnace Atomic Absorption Spectroscopy was used to assess Cr. According with the underlying disease, patients were divided into two groups: head and neck cancer (HNC) and neurological dysphagia (ND). All patients were fed with homemade meals. RESULTS A one hundred and twenty-nine patients (80 males), 26-95 years old were studied: HNC-52; ND-77. The observed data included low mean values of BMI from 71 patients; low Cr-8, low albumin-70, low transferrin-85 and 57 with both proteins low. Albumin was associated with survival time ( P =0.024) and there was a significant correlation between albumin and Cr (r=0.217, P =0.012). A good evolution of Cr and proteins values was observed, with no low Cr levels at T3. CONCLUSION Low serum Cr is rare in PEG-patients, with no relationship to other studied parameters. For the minority of patients displaying low Cr before gastrostomy, homemade PEG meals seem to be effective.RESUMO CONTEXTO Doentes submetidos a gastrostomia endoscópica percutânea apresentam desnutrição energético-proteica. Os elementos traço são necessários em pequenas quantidades e o Cromo (Cr) tem um papel importante no metabolismo. OBJECTIVO Pretendeu-se avaliar os níveis séricos de Cr e sua relação com as proteínas séricas, índice de massa corporal (IMC) e as doenças subjacentes nos primeiros 3 meses de alimentação por gastrostomia endoscópica percutânea. MÉTODOS Estudo prospetivo observacional durando 3 meses: avaliações no momento do procedimento (T0), após 4 (T1) e 12 semanas (T3). A avaliação inicial incluiu: idade, gênero, doença subjacente, Nutricional Risk Screening 2002 , IMC, concentração sérica de Cr, albumina e transferrina. Em T1 e T3, colheu-se sangue para Cr, albumina e transferrina. Para avaliação do Cr, utilizou-se espectrometria de absorção atómica em forno de grafite. Classificaram-se os doentes em dois grupos: neoplasias cervicofaciais (NCF) e disfagia neurológica (DN). Todos foram alimentados com alimentos de preparação doméstica. RESULTADOS Avaliaram-se 129 doentes (80 homens), entre 26-95 anos: NCF-52; DN-77. Encontraram-se valores baixos do IMC-71; Cr-8, albumina-70, transferrina-85 e 57 com ambas as proteínas baixas. Identificou-se correlação com significado estatístico entre a albumina e Cr (r=0,217, P =0,012) e entre a albumina e tempo de sobrevivência ( P =0,024). Foi observada boa evolução do Cr e proteínas, não sendo encontrados valores baixos de Cr em T3. CONCLUSÃO O Cr baixo é raro em doentes com gastrostomia endoscópica percutânea, sem relação com outros parâmetros, incluindo o tipo de doença subjacente. Para a minoria dos doentes com Cr baixo antes da gastrostomia, refeições de preparação doméstica parecem ser adequadas.
