The goal of this study was to investigate the effect of selenium deficit replenishment in patients with bronchial asthma (BA) on manifestations of oxidative stress and conditions of the antioxidant system (AOS). The need of correction of selenium deficit in BA-patients is determined by increased requirements in antioxidants due to chronic inflammatory process responsible for pathogenesis of BA. Latvia as well as Eastern Finland, Byelorussia, some regions of Ukraine, North-Western Russia, and New Zealand belong to the endemic areas with marked selenium deficit in soils and foodstuff. Twenty patients (7 men and 13 women) with selenium deficit and verified diagnosis of BA have been examined. In addition to basic therapy all patients received organic selenium as SelenoPRECISE (PharmaNord) 200 μg daily for 16 weeks. This caused statistically significant increase of plasma selenium from 50.94 ± 7.58 to 63.59 ± 10.87 μg/l ( p < 0.001), the increase of selenium-dependent glutathione peroxidase (from 38.64 ± 10.72 U/g Hb to 58.57 ± 14.64 U/g Hb, p = 0.01). Treatment of patients with selenium also normalized the parameters characterizing oxidative stress (chemiluminescence), significantly exceeded normal values before this treatment. The use of selenium in addition to basic therapy allows to abolish or reduce oxidative stress by correcting the antioxidant system. [ABSTRACT FROM AUTHOR] |
