Antibodies to Tumor Necrosis Factors in the Treatment of Rheumatoid Arthritis and Spondyloarthritis: The Basic Science, Clinical Science and Unmet Needs;Results from a Single Center

摘要

Inflammatory rheumatological diseases like rheumatoid arthritis (RA) and ankylosing spondylitis/Spondyloarthritis (AS/SpA), have been treated with NSAIDs (non steroidal anti-inflammatory drugs), corticosteroids, and DMARDs (disease modifying anti-rheumatic drugs).These have been only partially effective for the management of symptoms, since they are rarely associated with the complete control of disease and rarely slow down radiological damage. Several cytokines have been implicated in the pathogenesis of the inflammation and tumor necrosis factor (TNF) is the most important. The last decade and a half has seen advances in the form of “anti-TNF” therapies for RA and AS/SpA patients which target and neutralize the TNF cytokines, and thus reduce the disease activity. Two anti-TNF therapies have been used in India for treating DMARD resistant RA and AS/SpA for the last 13 years;Infliximab and Etanercept respectively. This paper is a description of the clinical outcomes and unmet needs/toxicities associated with the treatment of RA and AS/SpA with anti-TNF therapies (Infliximab, Etanercept), at a single rheumatology center (tertiary care, super-specialty hospital, Indraprastha Apollo Hospitals, New Delhi) in north India.
