Background. Rheumatoid ­arthritis is char­ac­ter­ized by an ­impaired ­immune ­response and a defec­tive cuta­ne­ous ­cell-medi­at­ed immu­nity has ­been report­ed. This ­study was real­ised in ­order to deter­mine the char­ac­ter­is­tics of cuta­ne­ous ­cell-medi­at­ed immu­nity in ­patients affect­ed by ­recent-­onset and untreat­ed rheu­ma­toid ­arthritis.
Methods. Forty-­enght ­patients affect­ed by new­ly diag­nosed rheu­ma­toid ­arthritis ­were stud­ied by ­skin test­ing ­with sev­en com­mon ­recall anti­gens. The ­skin ­tests ­were per­formed ­before the admin­is­tra­tion of dis­ease mod­i­fy­ing ­anti-rheu­mat­ic ­drugs (methot­rex­ate, cyclo­spo­rine-A, hydrox­ych­lor­o­quine) and ­were repeat­ed ­after ­four ­months of ther­a­py.
Results. 43.75% of the RA ­patients (21 out of 48) ­were ­defined as aner­gic com­pared ­with 2% of the nor­mal con­trol sub­jects and the ­rate of depres­sion of cuta­ne­ous ­cell-medi­at­ed immu­nity was not relat­ed ­either ­with the mark­ers of dis­ease activ­ity or ­with the clin­i­cal assess­ment. The ­impaired cuta­ne­ous ­cell-medi­at­ed immu­nity ­shows a ­slight improve­ment ­after methot­rex­ate ther­a­py, ­while cyclo­spo­rine-A and hydrox­ych­lor­o­quine ­were not ­able to ­achieve the ­same ­result.
Conclusions. Rheumatoid ­arthritis ­shows a defec­tive cuta­ne­ous ­cell-medi­at­ed immu­nity ­when the ­patients are stud­ied in the ear­ly ­phase of the dis­ease and ­before a sec­ond-­line of ther­a­py ­with dis­ease mod­i­fy­ing anti­-rheu­mat­ic ­drugs. The aner­gy ­does not cor­re­late ­either ­with the dis­ease activ­ity or ­with the ­short-­term ­response to treat­ment. The prog­nos­tic sig­nif­i­cance of ­these ­data ­remains uncer­tain.
