Treating severe systemic lupus erythematosus with rituximab. An open study.

Systemic lupus erythematosus (SLE) is an autoimmune disease that may be associated to high morbidity and mortality. Disease course is variable and unpredictable and although the prognosis and survival of these patients has dramatically improved, treatment of severe multiorganic organic affection in this condition remains a therapeutic challenge. Since B lymphocytes have an important role in the pathogenesis of SLE, it is expected that the targeting of these cells exerts a significant therapeutic effect in SLE patients with severe multiorganic manifestations.

Immune effects of therapy with Adalimumab in patients with rheumatoid arthritis.

The aim of this study was to assess the effect of Adalimumab on different immune parameters in patients with RA. Adalimumab was administered (40 mg every other week for 26 weeks) to eight patients with RA that were refractory to conventional drug therapy. Peripheral blood samples were obtained at days 0, 15 and 180 of Adalimumab therapy, and the following immune parameters were assessed: Number, phenotype, and function of regulatory T lymphocytes.
