Levels of interleukins 6 and 8 in psoriatic patients serum

Abstract EN

Recent progress in the understanding of psoriasis has shown that the regulation of local and systemic cytokines plays an important role in its pathogenesis.

Different studies evaluated the association of serum levels of some proinflammatory cytokines invivo and their correlation with severity of psoriasis.

Eighty cases of psoriatic patients had been studied.

Patients were divided into mild psoriasis group (30) and severe psoriasis group (50) according to severity, and (30) apparently healthy individuals ware used as acontrol group.

Sera samples of all groups were collected from all individuals for the estimation levels of interleukins (IL-6 and IL-8).

All mean values sera levels (IL-6 32.004 pg / ml and 17.579 pg / ml for IL-8) of patients were significantly higher than those of controls (12.640 and 8.860 pg / ml for IL-6and IL-8 respectively).

There was a high significant in sera levels of IL-6 and IL-8, in comparion with disease severity.

The levels of IL-6 and IL-8 were significantly higher in severe psoriatic patients than thos in mild type.

Furthermore, there was a positive correlation between the levels of IL-6, and IL-8 among the samples of psoriatic patients.

The measurements of serum levels of these cytokines may be objective parameters for the disease severity.
