Le psoriasis est influencé par : certains facteurs environnementaux (ex : infections et stress), les mauvaises habitudes de vie en ce qui a trait à l’exercice et l’alimentation, le tabagisme, la consommation d'alcool et les intolérances alimentaires telles que la sensibilité au gluten.
En raison des nombreux effets secondaires indésirables liés aux traitements médicaux traditionnels, plusieurs patients atteints de psoriasis étant insatisfaits, se tournent souvent vers l'utilisation de la médecine alternative et complémentaire tels que celle des suppléments nutritionnels.
La supplémentation en antioxydants coenzyme Q10, la vitamine E et le sélénium pourrait être envisageable pour la gestion des patients atteints de formes sévères de psoriasis.

Abstract
OBJECTIVE:
The aim of the present study was to evaluate clinical effects of supplementation with antioxidants to patients with severe erythrodermic (EP) and arthropathic (PsA) forms of psoriasis.
METHODS:
Fifty-eight patients were hospitalized, treated by conventional protocols, and randomly assigned to four groups. Groups EP1 and PsA1 were supplemented with coenzyme Q(10) (ubiquinone acetate, 50 mg/d), vitamin E (natural alpha-tocopherol, 50 mg/d), and selenium (aspartate salt, 48 mug/d) dissolved in soy lecithin for 30-35 d. Groups EP2 and PsA2 (placebo) received soy lecithin. Clinical conditions were assessed by severity parameters. Markers of oxidative stress included superoxide production, copper/zinc-superoxide dismutase, and catalase activities in the circulating granulocytes, in the affected epidermis, and plasma levels of nitrites/nitrates.
RESULTS:
At baseline patients had an increased superoxide release from granulocytes (10.0 +/- 0.5, 2.9 +/- 0.2, and 1.5 +/- 0.1 nmol/L per 10(6) cells/h for EP, PsA, and donors, respectively), increased copper/zinc-superoxide dismutase and catalase activities in granulocytes in EP patients and decreased in PsA patients, decreased activity of copper/zinc-superoxide dismutase (0.3 +/- 0.0, 1.8 +/- 0.1, and 2.2 +/- 0.2 U/mg protein for EP, PsA, and donors, respectively), and altered activity of catalase in psoriatic epidermis. Plasma levels of nitrites/nitrates were greater than normal in psoriatic patients. Supplementation resulted in significant improvement of clinical conditions, which corresponded to the faster versus placebo normalization of the oxidative stress markers.
CONCLUSION:
Supplementation with antioxidants coenzyme Q(10), vitamin E, and selenium could be feasible for the management of patients with severe forms of psoriasis.
