RESUMO

The chronic liver diseases can cause malabsorption of lipids and fat-soluble vitamins, leading to a deficient nutritional status. The aim of research was: to evaluate the relation between serum levels of fat-soluble vitamins (A, D and E) on chidren and adolescents with biliary atresia (BA) and auto-immune hepatitis (AIH) with the nutritional status and with laboratorial and clinic indicators. The study was transversal controlled, which were evaluated patients with AIH (n=25) and BA (n=24) and a control group (n=53) lined up by sex and age. The determination of serum levels of vitamins A, D and E was carried out by high performance liquid chromatography. Anthropometrics evaluation and classification of patients on Child-Pugh scale were also used. It was used the Mann-Whitney test, the correlation coefficient of Spearman and variance analysis for data analysis, which was considered significant difference if p<0.05. Have been evidenced that serum levels of vitamins A and E in healthful group were changed with age. The serum levels of vitamins A, D and E were higher in the healthful group when compared with the patients with BA and AIH together or isolated. No difference in the serum levels of vitamins A, D and E was noted in the BA group with or without cholestasis. The patients with BA and AIH together grouped and classified in Child C and Child B presented the lowest serum levels of vitamins A and E when compared to the patients classified in Child A. The nutritional deficit more intense was observed in the patients with BA and cholestasis. It was verified in the BA and AIH groups together a correlation weight/age (W/A), Triceps Skinfold Thickness (TST), Subscapular Skinfold Thickness (SST), Midarm Circunference (MC) and Midarm Fat Area (MFA), with the vitamins A and E. Besides indicators, the vitamin E was also correlated with Stature/Age (S/A), Body Mass Index (BMI), Midarm Muscle Area (MMA) and SKinfold Sum (SFS) for patients with AIH and BA together. In conclusion, have been observed deficiency of vitamins A, D and E in patients with AB and AIH. For higher serevity of disease, the serum levels of vitamins A e E are lower for patients with AB and AIH together. This same relation occurs for vitamins A and D for patients with AIH. When the nutrition status is evaluated, the patients with AB and cholestasis presented the highest nutritional deficiency. There is a correlation directly proportional, mainly of vitamin E with the anthropometric variables of the AB and AIH groups together.
