Abstract:
:To evaluate the role of red blood cell (RBC) antioxidants as clinical markers of oxidative exposure, we measured RBC glutathione (GSH) concentrations in 32 adult patients with cystic fibrosis (CF), and 8 healthy age-matched control subjects. We chose patients with CF because this disease is characterized by severe bronchial inflammation and marked oxidant-antioxidant imbalance. Although the GSH concentration of the two study groups was not significantly different, the RBC GSH concentration of patients with CF had a greater variability (p = 0.01) and was also inversely and significantly correlated to tests of pulmonary function (p < 0.05). These data indicate a large and significant interindividual variability of erythrocytic antioxidants in patients with CF, with a compensatory, but probably inadequate, increase in patients with more severe respiratory deterioration. Red blood cell GSH concentration may thus provide a biologic marker for disease severity and a rationale for antioxidant manipulation in these patients.
