In recent times, penteados has become increasingly relevant in various contexts. Contaminated Heparin Associated with Adverse Clinical Events and .... There is an urgent need to determine whether oversulfated chondroitin sulfate (OSCS), a compound contaminating heparin supplies worldwide, is the cause of the severe anaphylactoid reactions... Analysis and characterization of heparin impurities - PMC. This review discusses recent developments in analytical methods available for the sensitive separation, detection and structural characterization of heparin contaminants.
In relation to this, the adulteration of raw heparin with oversulfated chondroitin sulfate (OSCS) ... QUESTIONS AND ANSWERS ON HEPARINS - European Medicines Agency. • When giving OSCS-contaminated enoxaparin, doctors should: o avoid giving enoxaparin directly into an artery or vein; o closely monitor their patient for signs of allergic reactions; o be ready to administer the standard anti-allergy treatments, should such a reaction occur.
Techniques for Detection of Clinical Used Heparins - PMC. Meanwhile, the adverse effect in the clinical uses and the adulteration of oversulfated chondroitin sulfate (OSCS) in heparins develop additional attention to analyze the purity of heparins. European Medicines Agency recommends measures to manage contamination .... The European Medicines Agency has reviewed the risks associated with the use of heparin medicinal products contaminated with oversulphated chondroitin sulphate (OSCS).
Heparins are used to prevent and treat blood clots. Equally important, outbreak of Adverse Reactions Associated with Contaminated Heparin. Heparin contaminated with OSCS was epidemiologically linked to adverse reactions in this nationwide outbreak. The reported clinical features of many of the cases further support the conclusion...
Similarly, interactions of Oversulfated Chondroitin Sulfate (OSCS) From Different .... It is hypothesized that different OSCS preparations may alter the antithrombotic, bleeding, and hemo-dynamic profile of heparin. This investigation characterizes the effects of OSCS from different sources on the relative safety and efficacy of heparin in animal models of bleeding and thrombosis. Orthogonal analytical approaches to detect potential contaminants in ....
Recently, a contaminant, oversulfated chondroitin sulfate (OSCS), was discovered within heparin preparations. Furthermore, the presence of OSCS within heparin likely led to clinical manifestations, most prevalently, hypotension and abdominal pain leading to the deaths of several dozens of patients. Equally important, pRESS RELEASE - European Medicines Agency. The Agency’s Committee for Medicinal Products for Human Use (CHMP) concluded that: OSCS has been found in unfractionated (standard) and low-molecular-weight heparin; Comparison of the HMQC spectra of pure heparin, OSCS-contaminated ....
Recently, oversulfated chondroitin sulfate (OSCS) was identified in contaminated heparin preparations, which were linked to several adverse clinical events and deaths.
