Abstract
Objective To study the influence of antiinflammatory treatments, including methotrexate (MTX) and tumor necrosis factor (TNF) inhibitors, on antibody response following vaccination using a 7-valent conjugate pneumococcal vaccine in adult patients with established arthritis. Methods. Patients with rheumatoid arthritis (RA) or spondylarthropathy (SpA) (including psoriatic arthritis) were vaccinated (n = 505). All patients were stratified into 6 prespecified groups based on diagnosis and treatment (RA patients receiving MTX, RA patients receiving anti-TNF agents and MTX, RA patients receiving TNF inhibitors as monotherapy, SpA patients receiving anti-TNF agents and MTX, SpA patients receiving TNF inhibitors as monotherapy, and SpA patients...

Methods. Patients with rheumatoid arthritis (RA) or spondylarthropathy (SpA) (including psoriatic arthritis) were vaccinated (n = 505). All patients were stratified into 6 prespecified groups based on diagnosis and treatment (RA patients receiving MTX, RA patients receiving anti-TNF agents and MTX, RA patients receiving TNF inhibitors as monotherapy, SpA patients receiving anti-TNF agents and MTX, SpA patients receiving TNF inhibitors as monotherapy, and SpA patients receiving nonsteroidal antiinflammatory drugs [NSAIDs] and/or analgesics). SpA patients receiving only NSAIDs/analgesics served as a control group. All patients received 1 dose (0.5 ml) of vaccine intramuscu-larly. Levels of IgG antibodies against 23F and 6B serotypes were measured at vaccination and at 4-6 weeks following vaccination, using standardized enzyme-linked immunosorbent assays. Results. Positive antibody response was defined as an antibody response ratio (ARR) (i. e., ratio of post-to prevaccination antibody levels) of > 2. The ARR differed significantly between the groups. A better ARR was seen among patients in the control group compared to those in groups treated with MTX or MTX in combination with TNF inhibitors. Among patients treated with TNF inhibitors as monotherapy, ARRs for both serotypes were lower numerically, but were not significantly different, compared to those in controls. Ongoing MTX treatment was predictive of reduced response (odds ratio 0.41 [95% confidence interval 0.24-0.68], P = 0.001). Higher age was associated with impaired positive antibody response. Concomitant prednisolone treatment elicited better positive antibody response in patients with RA. Conclusion. Treatment with MTX and higher age were predictive of an impaired antibody response to the 7-valent conjugate pneumococcal vaccine in this cohort of patients with chronic arthritis. TNF inhibitors did not significantly affect antibody responses. (Less)
