FDA OKs new adhesive to treat burn victims

Mar 20 ,Medicine & Health


The U.S. Food and Drug Administration approved a medical adhesive -- a fibrin sealant called Artiss -- for use in attaching skin grafts to burn patients.

Fibrin sealants are tissue adhesives that contain the proteins fibrinogen and thrombin, which are essential in the clotting of blood. The FDA said Artiss differs from other fibrin sealants in that it contains a lower concentration of thrombin, allowing surgeons more time to position skin grafts over burns before the graft begins to adhere to the skin.

Artiss also contains aprotinin, a synthetic protein that delays the break down of blood clots.

"The approval of Artiss can help surgeons using a fibrin sealant to fine tune graft placement on burn sites," said Dr. Jesse Goodman director of the FDA's Center for Biologics Evaluation and Research. "The approval also provides an additional choice for health care professionals in providing burn treatment."

The fibrinogen and thrombin proteins in Artiss are derived from human plasma, collected from FDA-licensed plasma centers. Both proteins undergo purification and virus inactivation treatments to reduce the risk of blood-transmissible infections, the agency said.

Artiss is manufactured by the Baxter Healthcare Corp. of Deerfield, Ill.

Key found to breakthrough drug for clot victims
A team of researchers at Oregon Health & Science University and Washington University in St. Louis have described for the first time the mechanism that gives a mutant enzyme molecule that they have engineered – and patented – the potential to become a breakthrough drug for treating heart attacks and strokes.
Mechanism of blood clot elasticity revealed in high definition
Blood clots can save lives, staunching blood loss after injury, but they can also kill. Let loose in the bloodstream, a clot can cause a heart attack, stroke or pulmonary embolism.
Blood clotting protein linked to rheumatoid arthritis
Researchers at Cincinnati Children’s have issued the first study showing that a protein normally involved in blood clotting (fibrin), also plays an important role in the inflammatory response and development of rheumatoid arthritis. Inflammatory joint disease appears to be driven by the engagement of inflammatory cells with fibrin matrices through a specific integrin receptor, aMB2.
Blood-clotting protein may be new target for Alzheimer's drugs
Despite the rapid rise of Alzheimer’s disease — the Alzheimer’s Association predicts as many as 7.7 million cases by 2030 — there are no preventative treatments available, few in the pharmaceutical pipeline, and those drugs being developed all share the same two molecular targets. Now Rockefeller University researchers report that by targeting a different molecule, a blood-clotting protein called fibrin, they could reduce inflammation in the brains of mice with different models of the disease.
Study of staph shows how bacteria evolve resistance
Antibacterial resistance doesn’t happen overnight. But until recently nobody knew exactly how long it took — or how it happened at all. Now, by studying blood taken from a single patient over a period of months, Rockefeller University researchers have been able to trace how a common strain of bacteria adapted its genes to counteract the antibiotics used to try to kill it, until it finally emerged into the kind of fully resistant microbe that is wreaking havoc in hospitals worldwide. Total elapsed time: 90 days.
Researchers identify critical receptor in liver regeneration
In studies in mouse models, researchers at the University of California, San Diego (UCSD) School of Medicine have found that a cellular receptor involved in triggering cell death is also a necessary component of tissue repair and regeneration immediately following liver injury. This discovery could have implications for early intervention or therapy in liver disease such as cirrhosis or hepatitis.
Engineering the heart piece by piece
Some day, heart attack survivors might have a patch of laboratory-grown muscle placed in their heart, to replace areas that died during their attack. Children born with defective heart valves might get new ones that can grow in place, rather than being replaced every few years. And people with clogged or weak blood vessels might get a new “natural” replacement, instead of a factory-made one.
Inhibiting blood to save the brain
A fibrous protein called fibrinogen, found in circulating blood and important in blood clotting, can promote multiple sclerosis (MS) when it leaks from the blood into the brain, triggering inflammation that leads to MS-related nerve damage. Researchers at the University of California, San Diego (UCSD) School of Medicine have identified a fibrin-derived peptide that inhibits this specific inflammation process in mouse models of MS, reducing MS symptoms.
