RT Journal Article SR Electronic T1 Pulmonary complications of infliximab therapy in patients with rheumatoid arthritis. JF The Journal of Rheumatology JO J Rheumatol FD The Journal of Rheumatology SP 622 OP 628 VO 33 IS 3 A1 Ostör, Andrew J K A1 Chilvers, Edwin R A1 Somerville, Margaret F A1 Lim, Anita Y N A1 Lane, Suzanne E A1 Crisp, Adrian J A1 Scott, David G I YR 2006 UL http://www.jrheum.org/content/33/3/622.abstract AB We describe 5 patients with rheumatoid arthritis (RA) who developed pulmonary complications following infliximab therapy; 4 patients had preexisting usual interstitial pneumonia. As the pathophysiology of the pulmonary insult is unknown, we advise caution in the use of anti-tumor necrosis factor-alpha therapy in patients with RA with underlying lung disease of sufficient severity to withhold methotrexate treatment.
