TLDR
Various and severe OIs, especially those with intracellular micro-organisms, may develop in patients receiving anti-TNF treatment and steroid use >10 mg/day are independently associated with OI.
Abstract
Background Anti-tumour necrosis factor (TNF) therapy may be associated with opportunistic infections (OIs). Objective To describe the spectrum of non-tuberculosis OIs associated with anti-TNF therapy and identify their risk factors. Methods A 3-year national French registry (RATIO) collected all cases of OI in patients receiving anti-TNF treatment for any indication in France. A case–control study was performed with three controls treated with anti-TNF agents per case, matched for gender and underlying inflammatory disease. Results 45 cases were collected of non-TB OIs in 43 patients receiving infliximab (n=29), adalimumab (n=10) or etanercept (n=4) for rheumatoid arthritis (n=26), spondyloarthritides (n=3), inflammatory colitis (n=8), psoriasis (n=1) or other conditions (n=5). One-third (33%) of OIs were bacterial (4 listeriosis, 4 nocardiosis, 4 atypical mycobacteriosis, 3 non-typhoid salmonellosis), 40% were viral (8 severe herpes zoster, 3 varicella, 3 extensive herpes simplex, 4 disseminated cytomegalovirus infections), 22% were fungal (5 pneumocystosis, 3 invasive aspergillosis, 2 cryptococcosis) and 4% were parasitic (2 leishmaniasis). Ten patients (23%) required admission to the intensive care unit, and four patients (9%) died. Risk factors for OIs were treatment with infliximab (OR=17.6 (95% CI 4.3 - 72.9); p 10 mg/day or intravenous boluses during the previous year (OR=6.3 (2.0 to 20.0); p=0.002). Conclusion Various and severe OIs, especially those with intracellular micro-organisms, may develop in patients receiving anti-TNF treatment. Monoclonal anti-TNF antibody rather than soluble TNF receptor therapy and steroid use >10 mg/day are independently associated with OI.

Risk of Serious and Opportunistic Infections Associated With Treatment of Inflammatory Bowel Diseases.

TL;DR: Heterogeneity in risks of serious and opportunistic infections in patients treated with immune-suppressive regimens should be carefully considered and weighed against potential benefits for IBD treatment in patient management.

Cytokines as Therapeutic Targets in Rheumatoid Arthritis and Other Inflammatory Diseases

TL;DR: The key efficacy and safety trials for currently approved treatments in rheumatoid arthritis are provided and the major lessons learned from a decade of use in clinical practice are reviewed, focusing mainly on anti-TNF and anti-interleukin (IL)-6 agents.

Tuberculosis associated with infliximab, a tumor necrosis factor alpha-neutralizing agent

TL;DR: Infliximab is a humanized antibody against tumor necrosis factor α (TNF-α) that is used in the treatment of Crohn's disease and rheumatoid arthritis but there is no direct evidence of a protective role of TNF- α in patients with tuberculosis.

TL;DR: There is evidence of an increased risk of serious infections and a dose-dependent increasedrisk of malignancies in patients with rheumatoid arthritis treated with anti-TNF antibody therapy.

Rates of serious infection, including site-specific and bacterial intracellular infection, in rheumatoid arthritis patients receiving anti-tumor necrosis factor therapy: results from the British Society for Rheumatology Biologics Register.

TL;DR: In patients with active RA, anti-TNF therapy was not associated with increased risk of overall serious infection compared with DMARD treatment, after adjustment for baseline risk, but the rate of serious skin and soft tissue infections was increased, suggesting an important physiologic role of TNF in host defense in the skin andsoft tissues beyond that in other tissues.
