Improvements in our knowledge of its pathogenesis and advances in molecular biology have made possible to develop selective immunotherapy approaches. Tumor necrosis factor alfa (TNF alfa) is an important inflammatory mediator that play a crucial role in rheumatoid arthritis. This studies summarizes clinical essays that evaluate beneficial effects and tolerance of anti TNF alfa antibodies.

But some doubts persist concerning their long term side effects particularly infections, neoplasm or auto immune ones. High price of this treatment should evaluate report cost benefice to appreciate the better utilisation of these drugs.
