Complement Regulatory Proteins Expression and Clinical Response in Rheumatoid Arthritis (RA) Patients Treated With Rituximab

2014-08-27 03:14:52 | BioPortfolio

Summary

There is a correlation between the CD55, CD59, CD35 and CD46 expression on B lymphocytes of patients before and after treatment with rituximab and the level of depletion and repopulation time for these cells. The theoretical rationale of the study assumes that the correlation, if any, will be a negative correlation. However, the hypothesis of positive correlation (two-tailed test) will also be tested.

Description

Rituximab, an anti-CD20 monoclonal antibody, is a new alternative treatment for patients with severe immune diseases and resistance to conventional treatment. One of the mechanisms of action of this drug is the complement-mediated lysis. Most RA patients respond well to rituximab treatment, however, some are refractory and mechanism of this non-response is still unclear. The role of CD55 and CD59 protein and its overexpression as a mechanism of resistance to rituximab treatment in lymphoma patients have been investigated. However, there has not been studied a correlation between the intensity of expression of these regulatory molecules on B cells of RA patients and resistance to treatment with Rituximab.

Medical and Biotech [MESH] Definitions

Arthritis in children, with onset before 16 years of age. The terms juvenile rheumatoid arthritis (JRA) and juvenile idiopathic arthritis (JIA) refer to classification systems for chronic arthritis in children. Only one subtype of juvenile arthritis (polyarticular-onset, rheumatoid factor-positive) clinically resembles adult rheumatoid arthritis and is considered its childhood equivalent.

Rheumatoid arthritis of children occurring in three major subtypes defined by the symptoms present during the first six months following onset: systemic-onset (Still's Disease, Juvenile-Onset), polyarticular-onset, and pauciarticular-onset. Adult-onset cases of Still's disease (STILL'S DISEASE, ADULT-ONSET) are also known. Only one subtype of juvenile rheumatoid arthritis (polyarticular-onset, rheumatoid factor-positive) clinically resembles adult rheumatoid arthritis and is considered its childhood equivalent.

A variable mixture of the mono- and disodium salts of gold thiomalic acid used mainly for its anti-inflammatory action in the treatment of rheumatoid arthritis. It is most effective in active progressive rheumatoid arthritis and of little or no value in the presence of extensive deformities or in the treatment of other forms of arthritis.

Systemic-onset rheumatoid arthritis in adults. It differs from classical rheumatoid arthritis in that it is more often marked by acute febrile onset, and generalized lymphadenopathy and hepatosplenomegaly are more prominent.

Antibodies found in adult RHEUMATOID ARTHRITIS patients that are directed against GAMMA-CHAIN IMMUNOGLOBULINS.
