CDC study provides details on OSCS-laced heparin
The New England Journal of Medicine reported that the Centers for Disease Control and Prevention (CDC) in a study titled “Outbreak of Adverse Reactions Associated with Contaminated Heparin,” has confirmed the cause of serious adverse reactions in late 2007 were due to heparin contaminated with oversulfated chondroitin sulfate (OSCS). In the study, the CDC also determined that the contaminated heparin was linked to 152 adverse reactions in 113 patients from 13 states from Nov. 19, 2007 through Jan. 31, 2008.
