Drug News

Drug Warning

The US FDA is alerting health care professionals and patients treated with rituximab (Rituxan®, Genentech/ Biogen Idec) to reports of an emerging risk of a serious side-effect in patients receiving, or who have used rituximab. Two patients who were treated with this drug for systemic lupus erythematosus (SLE) developed progressive multifocal leukoencephalopathy, a fatal viral infection of the central nervous system. This side-effect has been reported in patients as late as 12 months after their last dose. SLE is not an approved indication for rituximab; it is approved only for the treatment of patients with non-Hodgkin’s lymphoma and patients with rheumatoid arthritis whose disease no longer responds to other common treatments. Health care professionals should report any serious adverse events possibly associated with the use of rituximab to the FDA’s MedWatch Adverse Event Reporting program online at www.fda.gov/MedWatch/report.htm, or by phone at 1-800-FDA-1088.

Psoriasis and Myocardial Infarction

In an article recently published in JAMA*, Gelfand, et al. report that psoriasis is an independent risk factor for myocardial infarction, and this risk is greatest in young patients with severe psoriasis. The authors conducted a large, prospective population-based cohort study to determine the risk of heart attack in patients aged 20-90 years with psoriasis while controlling for major cardiovascular risk factors.*Gelfand JM, et al. JAMA 296(14):1735-41 (2006 Oct).
