The evaluation of the effectiveness and costs showed that adalimumab and etanercept are more or less equal and favourable compared to infliximab in the first year of treatment.

Although, in the absence of sting challenge data it is not possible to draw conclusions about the predictive value of the LTT, our data may suggest that abolition of the LTT during VIT might indicate clinical insensitivity. Further studies, comparing the results of sting challenges, with the results of lymphocyte transformation will be necessary in order to evaluate the role of LTT in stopping immunotherapy.

To evaluate the role of interleukin-8 (IL-8) on the activation of neutrophils in rheumatoid arthritis (RA), we measured IL-8 and the adhesion molecules, L-selectin (CD62L), CD1 1b and CD18, on neutrophils in paired peripheral blood and synovial fluid of RA patients. Synovial fluid IL-8 levels were significantly increased compared to peripheral blood. L-selectin was split off and CD1 1b and CD 18 were upregulated on neutrophils in the synovial fluid. A positive correlation occurred between the IL-8 concentration and CD18 or CD1 1b densities on neutrophils in the synovial fluid (r = 0.75, P < 0.005 and r = 0.60, P < 0.05, respectively). Peripheral blood neutrophils of the patients were desensitised with IL-8 in vivo, as shown by the significantly lower L-selectin shedding after in vitro IL-8 stimulation: 1.6 times decrease for patients vs 3.2 for controls (P < 0.05). In conclusion, these results add further evidence for the role of IL-8 in the activation of neutrophils in RA.
