Evaluating severity and status in rheumatoid arthritis.

There is general agreement regarding the most appropriate examinations and methods to use to evaluate change in status in randomized controlled trials (RCT). However, no guidelines exist to aid in determining and evaluating actual status rather than change in status, particularly when applied to individual patients with rheumatoid arthritis (RA). In addition, methods appropriate for clinical trials may not be useful in evaluating individual patients because of time constraints.

Etanercept for the treatment of human immunodeficiency virus-associated psoriatic arthritis.

Etanercept may play an important role in modulating the inflammatory activity and progression of human immunodeficiency virus (HIV)-associated psoriasis and psoriatic arthritis. We report the case of a 45-year-old homosexual man with a CD4 cell count of less than 0.05 x 10(9)/L and an HIV viral load of 4200 copies/mL (while receiving highly active antiretroviral therapy) who developed extensive psoriatic plaques, 4.

VH usage and somatic hypermutation in peripheral blood B cells of patients with rheumatoid arthritis (RA).

The human antibody repertoire has been demonstrated to have a marked V-gene-dependent bias that is conserved between individuals. In RA patients, certain heavy chain V genes (VH) have been found to be preferentially used for encoding autoantibodies. To determine if such preferential use of VH genes in autoantibodies is associated with a general distortion of the V gene repertoire in RA patients, the VH composition of peripheral blood B cells was analysed among four RA patients and four age- and sex-matched healthy controls.
