Abstract:
Introduction: Psoriasis is a chronic, immune-mediated inflammatory dermatosis. The pathophysiology of the disease is still incompletely elucidated and multiple factors are said to be involved in its initiation and perpetuation, e.g., stressors, genetic factors, environmental factors. In the last decade, a new theory is trying to explain the pathophysiology of this disease by looking at the role played by oxidative stress and chronic inflammation in the initiation of keratinocyte proliferation and differentiation. Keeping in consideration the increased oxidative stress in the patients of psoriasis, the anti-oxidant drugs can form an important part of the therapeutic ladder of psoriasis.
Materials and Methods: The aim of this study was to measure the possible role of oxidative stress in psoriasis patient by measuring SOD level and comparing it with normal individuals and administer antioxidants supplements to the patients group to see the efficacy. It was a Case- Control study (1st part) and Clinical Trial without control group (2nd part). The study was carried out in Psoriasis awareness Club from June 2023 to December 2023. Purposive sampling done who fulfill the inclusion & exclusion criteria. 23 patients with psoriasis and 23 age and sex matched control subjects were recruited for this study. Clinical severity of the disease was determined by PASI score. All patients and control subjects were examined for plasma SOD level. 23 psoriatic patients were given antioxidant therapy in the form of once daily tablet for 30 days. PASI score, DLQI and SOD (Superoxide dismutase) level were measured before therapy (day 0) and after therapy (day 30) in patients group.
Statistical analysis and Results: Data were expressed as mean ± standard deviation (SD) for quantitative variables and numbers. For comparison of two means (t test) and (ANOVA "F") test were used for several means. Chi-square (χ2 ) or fisher exact test were used when appropriate, (P<0.05) was considered statistically significant. The mean age of the patients and control subjects were 37.64 (±5.89) and 33.6 (11.02) years, respectively. The mean duration of the disease was 12.43 (±8) years. No significant difference was observed between SOD level of psoriatic patients & controls. No significant correlations of SOD level with severity of psoriasis and duration of disease were found. We observed no statistically significant difference in PASI and DLQI scores before and after antioxidant therapy but there was significant increase in the level of SOD after treatment.
Conclusion: It is indisputable that antioxidant supplementation can reduce the overall morbidity, enhance the prognosis of psoriasis. Notably, in most cases, antioxidants alone are not able to induce significant clinical changes in the aspect and/or course of the disease, except perhaps in mild forms. They must be used in conjunction with standard pharmacological treatments to achieve measurable results.
