About

Rituximab is a very effective drug used to treat many inflammatory diseases. These diseases include, for example, rheumatoid arthritis, multiple sclerosis and systemic autoimmune diseases.

The major drawback of this drug is the risk of infection, which are favored by the direct effect of rituximab on the immune system. The risk of infection is one of the major reason not to prescribe or withdraw rituximab in several patients. However, many questions remain unanswered regarding the proportion and risk factors of infection or immunodeficiency induced by rituximab. Better understanding of these issues will help prescribing rituximab and properly monitor patients during their treatment. Moreover, as treatment with substitutive immunoglobulins might be a solution to decrease the risk of infections in those patients, it is very important to better characterize the risk and risk factors of rituximab-associated infection. The present study aims to answer these questions.
