What´s Rituximab Therapy? Essay -- Alternate Treatment, Biology, Antib

A relatively newer biologic, rituximab provides an alternative strategy for treating the presenting tolerant. A genetically engineered chimeric anti-CD20 monoclonal antibody, rituximab exerts it therapeutic action by selectively targeting CD-20 plus B-cells1212, 18. As CD-20 is expressed exclusively on pre-B and mature B lymphocytes infrastructure cells and plasma cells are not implicated in rituximab therapy. The over pattern of B-cells expressing the CD-20 surface antigen in the synovium of RA-affected joints has been well established18. The electromotive force mechanisms by which these B-cells set in to the immunopathogenesis of RA are as follows they can act as antigen presenting cells, unloose pro-inflammatory cytokines (including tumour necrosis factor-alpha), and generate flea-bitten factor (RF) and new(prenominal) auto-antibodies whilst also activating T cells12. Hence, the rituximab mediated depletion of B-cells is thought to prevent these potential mechanisms from occurring thus controlling the progression of the disease18. Rituximab therapy consists of two 1000mg infusions, given two weeks isolated at intervals of no less than 2 weeks. The projected cost of a single course of rituximab therapy is around 349211 and if clinically efficient would offer the patient a more convenient dosing schedule compared to Anti-TNF therapy. The annual cost does stock-still depend on how often the patient is required to undergo a course of rituximab therapy11. An RCT aimed at investigating different rituximab dosing regimens in methotrexate foul patients referred to as the DANCER trial, provides significant evidence conveying the potential service of rituximab therapy19. As part of the trial, patients received rituximab 500MG, rituximab 1000mg or placeb... ...50 (7) 754--766.27.Kaneko A.
