چکیده

Plasma salicylate concentration was monitored in 42 children on long-term salicylate therapy for rheumatoid arthritis. A given dose of salicylate per kg resulted in large variations in plasma levels, both between individuals and for a single individual at different times. The factors responsible for such variations were studied; in 6 cases urinary metabolites of salicylate were analysed. The relation between salicylate dosage and plasma half-life accounts for the fact that small changes in dosage can result in large changes in plasma concentration. The addition of corticosteroid or ACTH therapy results in lower plasma levels of salicylate, and necessitates higher dosage of salicylate. After the introduction of routine monitoring of plasma salicylate, the incidence of toxic symptoms fell sharply.

Chronic salicylate administration in juvenile rheumatoid arthritis: aspirin "hepatitis" and its clinical significance.

Salicylates provide the backbone of therapy in juvenile rheumatoid arthritis. They are effective in controlling the disease approximately 75% of the time if they are properly used. Salicylate administration is relatively safe if carefully done. Serum salicylate levels should not exceed 30 mg/dl routinely. Patients, physicians, and parents should be alert to early clinical signs of toxicity. Chi...

Investigation of the plasma levels of CCL-17 and CCL-25 and their receptor gene expression in rheumatoid arthritis patients

Background and Aim: Rheumatoid arthritis (RA) is an autoimmune inflammatory disease of unknown etiology.  The chemokines and their related receptors have a pivotal role in migration and homing of leukocyte involved in the pathogenesis of RA. The goal of this study was to measure the plasma levels of CCL-17 and CCL-25 and their receptors gene (CCR4 and CCR9) expression in rheumatoid arthritis pa...

Evidence for activation of the alternate complement pathway in patients with juvenile rheumatoid arthritis.

OBJECTIVE Complement activation has been shown to occur in patients with juvenile rheumatoid arthritis (JRA). Since the two pathways of complement are activated by different stimuli (the alternate pathway by microbial products and IgA, and the classical pathway by immune complexes), we decided to study the relative contribution of the two pathways of complement activation in patients with JRA. ...
