The relationship of FcgammaRIIIagenotype to degree of B cell depletion by <strong>rituximab</strong> in the treatment of systemic lupus erythematosus. Arthritis Rheum.2003 Feb;48(2):455-9.OBJECTIVE: Despite wide use of the anti-CD20 monoclonal antibody <strong>rituximab</strong> in the treatment of B cell lymphomas,the mechanism by which it causes B cell depletion remains a subject of controversy. As part of an ongoing phase I/II trialof <strong>rituximab</strong> in the treatment of systemic lupus erythematosus (SLE), we sought to determine whether the effectivenessof B cell depletion was influenced by polymorphisms of Fc receptors (FcR) on effector cells. METHODS: During<strong>rituximab</strong> treatment of 12 SLE patients, B cell depletion was monitored as a function of the serum <strong>rituximab</strong> level andFcgammaRIIa and FcgammaRIIIa genotypes at baseline and at 1 month and 2 months after treatment. FcR genotypeswere determined by polymerase chain reaction. Serum levels of <strong>rituximab</strong> were measured by enzyme-linkedimmunosorbent assay (ELISA). B lymphocyte percentages were assessed by flow cytometry. RESULTS: B cell depletionwas highly variable in this patient cohort, with B cell percentages at the 1-2-month posttreatment nadir ranging fromundetectable (
