Tuberculosis reactivation during immunosuppressive therapy in rheumatic diseases: diagnostic and therapeutic strategiesKeane, Josepha; Bresnihan, BarrybCurrent Opinion in Rheumatology: July 2008 - Volume 20 - Issue 4 - p 443–449 doi: 10.1097/BOR.0b013e3283025ec2 Infectious arthritis and immune dysfunction: Edited by Dimitrios Vassilopoulos Abstract Author Information Purpose of review: Biological agents used to treat rheumatologic conditions have made a significant impact on these difficult to treat autoimmune diseases. The tradeoff has been an increase in infections, and particularly tuberculosis with tumor necrosis factor blocker use. Because reactivation of latent tuberculosis infection is preventable, new data have demonstrated that these agents can be made safer when the clinician addresses latent tuberculosis infection. Recent findings: Research that supports the screening and treatment of rheumatology patients with latent tuberculosis infection is reviewed, and the emerging consensus on how best to do this is discussed. The limitations of testing to rule out latent tuberculosis infection in this group is emphasized, as this often prevents the tumor necrosis factor blocker prescriber from offering the patient complete reassurance with regard to tuberculosis risk. Summary: Findings to date support the close screening and treatment for tumor necrosis factor in this uniquely vulnerable group. Such vigilance should probably be applied to future drugs that interfere with cytokines known to play a role in tuberculosis immunity. aSt. James's Hospital and Trinity College Dublin, Ireland bSt. Vincent's University Hospital, Dublin, Ireland Correspondence to Joseph Keane, St. James's Hospital, CResT, Dublin 8, Ireland Tel: +353 1 8962101; e-mail: email@example.com © 2008 Lippincott Williams & Wilkins, Inc.
