Abstract
The aim of this study was to examine serum levels of β-2-microglobulin (b-2-m) in 132 children at various stages for the evaluation of celiac disease (CD). Serum b-2-m was analyzed by a radio immunossay (RIA) method, using a β-2-micro RIA kit (Pharmacia, Uppsala, Sweden). The mean concentration of b-2-m in children with an established diagnosis of CD was 4.38±1.86 mg/l. In children receiving a gluten-free diet, the mean b-2-m concentration was 1.95±1.09mg/l, and in children who received a gluten-containing diet, the concentration was 3.19±0.71mg/l. In children with CD who were on a gluten-free diet and who presented no antibodies against EmA in class IgA serum, b-2-m concentration was within the normal range (1.86±0.55mg/l). The concentration of b-2-m in children with secondary malabsorption syndrome was within the physiological range (1.77±0.64mg/l). In children with IgA-EmA antibodies present in serum, the b-2-m concentration was significantly higher (3.5±1.23mg/l;P<0.001) than that in children with IgA-EmA in serum. We showed a linear dependence between the degree of villous atrophy in CD and concentrations of b-2-m in serum (r 2=0.94). Determination of b-2-m concentration in sera of children with CD may be used to monitor treatment with a gluten-free diet and to differentiate secondary malabsorption syndrome from CD.
