Tumor necrosis factor (TNF)-alpha inhibitors (infliximab, adalimumab, and etanercept) used in immune-mediated inflammatory diseases such as rheumatoid arthritis, Crohn's disease, or psoriatic arthritis have the potential to increase the risk of infectious complications. Pulmonary infections are one of the most frequent complications associated with the use of TNF inhibitors. This article provides an overview of the distinct types of infectious pulmonary complications seen in patients using these anticytokine drugs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
