Introduction. The aim of the present study is to discuss the importance of the processes of oxidative stress in the pathogenesis of certain autoimmune diseases, to search for an appropriate assessment marker, and to debate current approaches which have been proposed for the treatment of Rheumatoid Arthritis (RA), Psoriatic Arthritis (PsA), and Psoriasis (Ps). Materials and methods. The total antioxidant capacity (TAC), the thiolic capacity (TC), and the serum hydroperoxide concentration (SHC) were measured in 37 subjects: 13 with RA, 8 with PsA, 8 with Ps, and 8 healthy controls. Results. SHC levels were significantly higher in patients with RA (p = 0.01), as well as in those with PsA (p = 0.005) and Ps (p = 0.002) in comparison with the control group. However, a significant reduction in the TAC values in the serum of all three groups (RA, p = 0.03; PsA, p = 0.005; Ps,p = 0.001) were observed in comparison with the healthy controls. The thiolic concentration were found to have significantly diminished in patients with RA (p =0.0005) and Ps (p = 0.0005) in comparison with the control group. Our findings have brought out the fact that the therapeutic treatment of RA using biological drugs is more than satisfactory in accord with the considerable increase in the TAC values, although not significantly, compared to those patients treated with DMARDs. Conclusions. The determination of the parameters of oxidative stress utilising these methods may be useful as a quick test, and as routine in monitoring the state of oxidative stress in patients suffering from RA, PsA, and Ps, so that a more effective treatment for ROS can be undertaken accordingly. The administration of biological drugs seems to have a role in increasing the mechanism of the barrier which the body possesses against oxidative stress.

Abstract

Introduction. The aim of the present study is to discuss the importance of the processes of oxidative stress in the pathogenesis of certain autoimmune diseases, to search for an appropriate assessment marker, and to debate current approaches which have been proposed for the treatment of Rheumatoid Arthritis (RA), Psoriatic Arthritis (PsA), and Psoriasis (Ps). Materials and methods. The total antioxidant capacity (TAC), the thiolic capacity (TC), and the serum hydroperoxide concentration (SHC) were measured in 37 subjects: 13 with RA, 8 with PsA, 8 with Ps, and 8 healthy controls. Results. SHC levels were significantly higher in patients with RA (p = 0.01), as well as in those with PsA (p = 0.005) and Ps (p = 0.002) in comparison with the control group. However, a significant reduction in the TAC values in the serum of all three groups (RA, p = 0.03; PsA, p = 0.005; Ps,p = 0.001) were observed in comparison with the healthy controls. The thiolic concentration were found to have significantly diminished in patients with RA (p =0.0005) and Ps (p = 0.0005) in comparison with the control group. Our findings have brought out the fact that the therapeutic treatment of RA using biological drugs is more than satisfactory in accord with the considerable increase in the TAC values, although not significantly, compared to those patients treated with DMARDs. Conclusions. The determination of the parameters of oxidative stress utilising these methods may be useful as a quick test, and as routine in monitoring the state of oxidative stress in patients suffering from RA, PsA, and Ps, so that a more effective treatment for ROS can be undertaken accordingly. The administration of biological drugs seems to have a role in increasing the mechanism of the barrier which the body possesses against oxidative stress.
