Statistics from

The development of anti-infliximab antibodies in 8% to 43% of infliximab-treated patients is associated with decreased efficiency and increased risk of adverse effects.13 An intervention that can diminish anti-infliximab antibody formation is therefore warranted. Rituximab, a chimeric monoclonal antibody that selectively depletes CD20-positive B lymphocytes, could potentially inhibit the human antibody response against infliximab. Therefore, we assessed the proportion of patients with rheumatoid arthritis (RA) in which treatment with rituximab resulted in the depletion of anti-infliximab antibodies.

Consecutive patients with RA with detectable anti-infliximab antibodies, who were initiated on treatment with either rituximab or adalimumab, were included in this prospective controlled cohort study. …
