Abstract

Introduction: Alterations in the cellular redox state have been described as causal factors in various diseases. Reduced glutathione depletion has been fundamentally associated with neurodegenerative, pulmonary, liver, cardiovascular and immunological diseases.

Objective: To determine the concentrations of reduced glutathione and the cellular redox status in pediatric patients with immunodeficiencies.

Methods: We studied 21 patients with immunodeficiencies from the immunogenetic service, aged between 1 and 8 years and as a control group, 8 children in the same age range as the patients, with normal humoral and cellular immunity studies. Patients diagnosed with immunodeficiency were divided into two groups according to the affected component of the immune response: humoral and cellular. The intraerythrocyte concentrations of oxidized and reduced glutathione were determined by means of an HPLC-UV method. To evaluate the cellular redox state, the relationship between the reduced and oxidized forms of glutathione (GSH/GSSG) was calculated.

Results: Reduced glutathione concentrations and cellular redox status were found to be decreased in both groups of patients in relation to children without immunodeficiency (p=0,031 and p=0,03; respectively). Oxidized glutathione showed no difference between the groups.

Conclusions: In patients with immunodeficiency, the cellular redox state is affected as a consequence of the decrease in reduced glutathione. This first approach offers the potential for the use of these biomarkers in the comprehensive evaluation of patients with immunodeficiency.
