The role of etanercept on the expression of markers of T helper 17 cells and their precursors in skin lesions of patients with psoriasis vulgaris.

Very recently, it has been demonstrated that CD161, retinoic acid-related orphan receptor gamma-t (RORgamma-t) and CC-chemokin receptor 6 (CCR6) can be considered good surface markers to detect T helper 17 cells and their precursors, T cell populations that are considered to play an important role in the pathogenesis of psoriasis. In the present study, we evaluate the clinical involvement by calculating the PASI score and the number of CD4+, CD161+, RORgammat+ and CCR6+ cells before and after a 12-week course with etanercept or acitretin in patients with moderate-to-severe, plaque-type psoriasis vulgaris. Ten patients were given etanercept 50 mg twice weekly and 10 patients acitretin 0.

[Correlation between different clinical activity and anti CC-P (anti-cyclic citrullinated peptide antibodies) titres in rheumatoid arthritis treated with three different tumor necrosis factors TNF-alpha blockers].

TNF-alpha role in RA is confirmed by the improvement on joint inflammation and physical function and by the slowing of radiographic damage induced by TNF-alpha blockers, that also reduce Rheumatoid Factor (RF) and anti-CC-P titres. (1) To evaluate the effects of 3 TNF-alpha blockers on (a) disability (HAQ), disease activity (DAS28), acute phase reactants (ERS, CRP); (b) autoantibodies: IgM RF, anti-CCP abs. (2) To evaluate if anti-CCP abs could be useful for testing the efficacy of anti-TNF-alpha agents in the follow-up of RA patients.
