Relação entre estado nutricional e atividade inflamatória em pacientes com doença inflamatória intestinal Relationship between nutritional status and inflammatory activity in patients with inflammatory bowel disease

RACIONAL: As doenças inflamatórias intestinais caracterizam-se por diversos sintomas que afetam o aparelho digestório e, consequentemente, podem interferir sobre o estado nutricional. OBJETIVO: Avaliar o estado nutricional de pacientes com doença inflamatória intestinal em diferentes estágios de atividade inflamatória. MÉTODOS: Foram avaliados 55 pacientes com doença inflamatória intestinal, por meio de dados antropométricos, com aferição de peso, altura, circunferência do braço e prega cutânea do tríceps e tiveram sua composição corporal determinada por impedância bioelétrica. Para determinação de atividade inflamatória da doença foram utilizados os níveis séricos de proteína C reativa e o índice de Harvey e Bradshaw. Para comparação de médias foi usado o teste t não pareado, e para as médias não paramétricas, o teste de Mann-Whitney, considerando nível de significância valor de pBACKGROUND: The inflammatory bowel diseases are characterized by multiple digestive tract symptoms and therefore may interfere with nutritional status. AIM: To assess the nutritional status of patients with inflammatory bowel disease in different stages of inflammatory activity. METHODS: Fifty five patients with inflammatory bowel disease were demographically evaluated with weight measurement, height, arm circumference and triceps skinfold and had their body composition determined by bioelectrical impedance. For determination of inflammatory activity of the disease were used serum C-reactive protein and the index of Harvey and Bradshaw. To compare means it was used the unpaired t test, and the average non-parametric, the Mann-Whitney test, level of significance p <0.05. RESULTS: Among the patients, 28 had Crohn's disease and 27 ulcerative colitis, aged between 19 and 63 years and time since diagnosis 1-22 years. There was no difference in anthropometric measurements and body composition of patients whose disease was inflammatory activity or in remission. Patients who used glucocorticoids in the six months preceding the assessment showed body fat percentage of 23.4 ± 8.2% whilst those who did not use the percentage was 30.7 ± 11.3 (p
