E-mail: [email protected] , In a recent issue and elsewhere [1, 2] we reported five cases of life-threatening refractory systemic lupus erythematosus (SLE). In May 2004, one of the patients had a flare-up after 18 months’ remission and infusion of rituximab was employed again.

The antigen specificity of chimeric mAb is the same as the parental mouse antibodies; however, the human Fc region renders a longer in vivo half-life than the parent murine mAb and similar effector functions as the human Ab. Chimeric antibodies are generally around two thirds human, reducing the risk of a reaction to foreign antibodies from a non-human animal when they are used in therapeutic treatments. A closely related concept is a humanized antibody, made in a similar way but containing closer to 90% human genetic material. Humanized antibodies are antibodies from non-human species whose protein sequences have been modified to increase their similarity to antibody variants produced naturally in humans. The process of "humanization" is usually applied to monoclonal antibodies developed for administration to humans for example, antibodies developed as anti-cancer drugs. Humanization can be necessary when the. There is growing evidence for the efficacy of rituximab in refractory SLE [1–5]. However, it did not reduce disease activity because of the development of anti-human chimeric antibody (HACA) against rituximab.

Data from case series and retrospective and open-label studies support the use of hydroxychloroquine in the treatment of extensive cutaneous sarcoidosis Chong 2005, Jones 1990, Modi 2008.

Hydroxychloroquine HCQ is used for the treatment of patients with rheumatic diseases. We tested the hypothesis that HCQ affects the NLRP3 inflammasome, which is involved in autoinflammation. Human neutrophils were stimulated with serum amyloid A SAA in vitro and measured for IL-1β and caspase-1 p20 secretion by ELISA. Pro-IL-1β mRNA expression in human neutrophils was quantified by.
