Antioxidants as adjuvant therapy in rheumatoid disease. A preliminary study.

The aim of the present study was to assess the therapeutic value of adding a high dose of vitamin E or an antioxidant combination to the treatment regimen of the rheumatoid disease. The study was carried out on 30 patients with rheumatoid disease diagnosed according to the criteria of American Rheumatism Association (ARA), subvided into three equal groups. Patients in group I received a standard treatment of intramuscular methotrexate (CAS 59-05-2; 12.5 mg/week), oral sulphasalazine (CAS 599-79-1; 0.5 g b.i.d.) and indometacin (CAS 53-86-1; 100 mg suppository at bed-time). In group II the patients received the standard treatment plus a combination of antioxidants. Patients in group III received a high dose of vitamin E (400 mg t.i.d.) in addition to the standard treatment. The disease state was evaluated using Ritchle's articular score index and the duration of morning stiffness. Laboratory evaluations included the rheumatoid factor, erythrocyte sedimentation rate (ESR), plasma levels of vitamin E and malonedialdehyde (MDA), and the activity of glutathione peroxidase (GPx). In the group receiving the standard regimen, the patients started to feel tangible improvement by the end of the second month. With adjuvant therapy of either the antioxidant combination or a high dose of vitamin E the symptoms of arthritis were better controlled from the first month. By the end of the second month, the values of the three monitoring tests were significantly decreased indicating better control of the disease. The percentage increase in the activity of GPx was highest in patients taking the antioxidant combination and least in those taking the standard treatment. The decrease in plasma MDA followed the same pattern. With adjuvant therapy, the vitamin E level in plasma increased with the duration of treatment. The results obtained in the present study are encouraging. The clinical improvement and the shift in the disease indices towards normal make the use of antioxidants as adjuvant therapy in rheumatoid disease worth pursuing.
