Influence of methotrexate on the frequency of postoperative infectious complications in patients with rheumatoid arthritis.
OBJECTIVE
To evaluate the influence of methotrexate (MTX) on the frequency of postoperative complications in patients with rheumatoid arthritis (RA).


METHODS
We conducted a randomized unblinded prospective study in 64 patients with RA treated with MTX and who underwent orthopedic surgery. Two groups of patients were constituted: in Group A (32 patients), MTX was interrupted 7 days before the surgery; in Group B (32 patients), MTX was not discontinued.


RESULTS
Fifty surgical procedures were performed in Group A and 39 procedures in Group B. No postoperative infection was observed in any group. A prolonged wound healing was noticed in 6 cases in Group A and in 4 cases in Group B (not significant).


CONCLUSIONS
We suggest that the interruption of MTX is not required in patients with RA when an orthopedic surgical treatment is planned. However a large prospective study is needed to make a definitive conclusion.
