Efficacy and Safety of Rituximab in Connective Tissue Disease related Interstitial Lung Disease.

Background: Pulmonary complications of connective tissue disease are being identified more frequently with the advent of more sophisticated radiological investigations. Limited previous studies have suggested Rituximab (RTX), a chimeric monoclonal antibody with activity against CD-20, may benefit connective tissue disease patients with pulmonary complications. We performed a retrospective analysis of the efficacy and safety of RTX in patients attending a tertiary referral centre.
