Listing a study does not mean it has been evaluated by the U. TNF-α, IL-1 and IL-6 are known to have primary roles in the pathogenesis of rheumatoid arthritis and other inflammatory diseases.

Study protocol required hydroxychloroquine initiation or maintenance at 400 mg by 10 weeks of gestation for all participants. Additionally, investigators sought to determine if treatment would decrease the rate of recurrence below the historical standard, which Izmirly pointed out previously published research has suggested is 18%. Chloroquine and its congener, hydroxychloroquine, have been successfully used in the treatment of rheumatoid arthritis. 18 – 20 The therapeutic serum concentration of chloroquine is reported to be 06–09 µ m in man at a clinically safe dose. 40 However, the levels of chloroquine in liver, spleen and leucocytes are much higher and found to be between 100 and 300 µ m, a concentration range that is higher than that at which we observed its effect in U-937 cells. We examined the underlying mechanisms involved in the chloroquine-induced inhibition of cytokine production.. The anti-rheumatic drug chloroquine has been shown to inhibit TNF-α, IL-1 and IL-6 production from mononuclear phagocytes.

To study the effect of experimental diabetes and arthritis on the pharmacokinetics of hydroxychloroquine HCQ enantiomers in rats. Methods. The pharmacokinetic studies were carried out following administration of 40 mg/kg of racemic HCQ to diabetic, insulin-treated diabetic, adjuvant arthritic and control rats. A previous study showed that the intracellular level of hydroxychloroquine in mononuclear cells from patients receiving a standard dose of 400 mg daily for at least 3 months was similar to that in mononuclear cells incubated in vitro with 100 μ m chloroquine or hydroxychloroquine for 1 h. These results strongly suggest that therapeutic doses. Methods/design. HERO is an investigator-initiated, multicentre, randomized, double-blind, placebo-controlled trial. A total of 252 subjects with symptomatic hand OA will be recruited across primary and secondary care sites in the UK and randomized on a 11 basis to active treatment or placebo for 12 months.
