Abstract
Aim: The purpose of the study was to determine the characteristics of endogenous intoxication parameters, biochemical protection and reveal their
interaction in children with celiac disease. Materials and methods: 81 children aged from 1 to 16 years with celiac disease were examined in acute and remission periods. In erythrocytes, blood serum and urine we determined low and moderate molecular weight substances (LMMWS), oligopeptides (OP); in erythrocytes — the value of erythrocyte mechanical hemolysis (MH), malondialdehyde (MDA) content, the activity of glutathione reductase (GR) and superoxide dismutase (SOD); in blood serum — ceruloplasmin (CP) level, alcohol dehydrogenase (ADH) activity; in erythrocytes and blood serum — glutathione transferase (GT), and calculated intoxication index (II). Results: In children with celiac disease in acute and remission periods LMMWS, OP, II levels in blood were statistically significantly high, while LMMWS level in urine was low. In both periods MH activity was high (p <0.001), and GSR (p <0.001) and SOD (p <0.01) levels were low. We revealed the correlation between MDA and II (r =0.67; p =0.006), erythrocyte LMMWS and SOD (r = -0.61; p =0.015), erythrocyte LMMWS and ADH (r =0.62; p =0.006), between GT and OP in urine (r = -0.31; p =0.026), GT and MDA (r =0.68; p =0.000), GT and MH (r = -0.46; p =0.004), between MDA and CP (r =0.57; p =0.002) that made it possible to develop the models of dependence of the parameters in relation to each other. Conclusion: In celiac disease there is endogenous intoxication. The changes of the first and the second phases of biotransformation, antioxidant protection is an essential factor of the disease pathogenesis, since they have an effect on endogenous intoxication formation that should be taken into consideration in therapy.
