New onset of articular inflammatory manifestations in patients with hidradenitis suppurativa under treatment with infliximab.

OBJECTIVES

Severe hidradenitis suppurativa (HS), under infliximab, can be associated with different forms of arthritis whose mechanism is unclear. Our objective is to establish the frequency and clinical presentation of new-onset arthritis in HS under infliximab.

METHODS

Severe HS patients under infliximab were followed up between 2007-2012. New articular inflammatory manifestations were investigated by rheumatologist.

RESULTS

Three patients over eleven developed a polyarthritis. Mean duration of arthritis was 3 months. At treatment's stop: 2 patients improved and 1 relieved with adalimumab.

CONCLUSION

The inflammatory rheumatism's frequency in HS under infliximab seems underestimated.
