Abstract
We evaluated the effectiveness of concomitant treatment with methotrexate (MTX) plus micronutrients in comparison with monotherapy with MTX only in psoriasis patients. Plasma levels of interleukin-1 beta (IL-1β) and tumor necrosis factor alpha (TNF-α) were also measured and their association with clinical severity was evaluated. Thirty psoriasis patients 20 to 50 years old with a PASI score > 10 were divided randomly into two groups. Both groups were given oral methotrexate (0.2-0.3 mg/kg/week) for 12 weeks. In addition, Group B received one tablet of micronutrient supplement daily. Disease severity was calculated using the psoriasis area and severity index (PASI) score before and after 12 weeks. Levels of IL-1β and TNF-α were measured using enzyme-linked immunosorbent assay (ELISA). We found that 13 (86.6%) patients in Group B and 8 (53.3%) patients in Group A attained a mild PASI score (≤ 10% body involvement). IL-1β and TNF-α levels were significantly decreased in favor of Group B (p < 0.05). There was a significant correlation between changes in both IL-1β and TNF-α levels and PASI score after the study (p < 0.05). The results obtained were positive, and therefore double-blind randomized trials with a larger sample size are highly suggested to confirm or reject these results.
