-------------------------------- "Contaminant Found in Heparin"
"FDA Probes How Compound Got Into Blood-Thinning Drug"
By Marc Kaufman Washington Post Staff Writer Thursday, March 6, 2008; A03
The U.S. Food and Drug Administration has detected a "contaminant" in many samples of Chinese-supplied heparin that may be the cause of hundreds of severe and sometimes deadly allergic reactions to the blood-thinning drug, agency officials said yesterday.
Chief Medical Officer Janet Woodcock said the agency is investigating whether the presence of the contaminant, a large molecule similar to heparin, was the result of faulty manufacturing or was intentionally added to reduce costs.
"We don't know how this heparin-like compound got into the heparin, but we are aggressively investigating it," Woodcock said.
Millions of Americans are treated every year with the drug, which is widely used in surgery and kidney dialysis. The FDA yesterday increased from four to 19 its estimate of the number of patients who may have died as a result of reactions to the drug.
Since the initial deaths associated with heparin were reported more than three weeks ago, the episode has intensified concern over the safety of foods, drugs and other products imported from China and other developing countries with limited regulatory agencies. Some in Congress have questioned whether the FDA has the resources or the will to exercise the same kind of oversight over foreign drugmakers -- which supply a large and growing share of the drugs and drug ingredients sold in the United States -- that it gives to domestic drugmakers.
The active ingredient for much of the heparin used in the United States comes from China, but the problematic batches were sold only by Baxter International, which gets the raw product through intermediaries from a plant outside Shanghai. FDA officials have acknowledged that the agency never inspected the Changzhou SPL plant, apparently because it was mistaken for another plant with a similar name.
Woodcock said the contamination came to light only through a sophisticated test never before used on heparin. She said 5 percent to 20 percent of samples were found to contain the contaminant, but all would have been deemed safe under the standard testing procedures. The substance had never before been detected, she said.
The agency detected a spike in reported severe reactions to Baxter's heparin -- including anaphylactic shock, fainting and a racing heartbeat -- in early February.
While it remains uncertain whether the contaminant caused the adverse reactions and deaths, Woodcock said the FDA and company think there may be a connection. They also suspect that the problem came from the Chinese active ingredients and not from a problem with Baxter's finishing plant in New Jersey.
Heparin, which has been used in medicine for more than 60 years, is made from a compound found in pig intestines. Heparin injections are used to prevent blood clots in people undergoing dialysis and surgery.
Baxter, which supplies about half of the U.S. market, sold 35 million vials last year. Virtually all of the nation's 450,000 dialysis patients use heparin regularly.
In a teleconference, Woodcock and FDA Commissioner Andrew von Eschenbach defended the agency's oversight of the fast-growing number of foreign manufacturers of drugs and drug ingredients. They said the plants are monitored by a complex system of international and local oversight, and supported by quality controls built into their system designs.
Von Eschenbach said his agency plans to do more, but also said many products made in places such as China are tongue depressors or other items that do not need intense oversight.
The issue of foreign inspections of food and drugmakers in lightly regulated nations such as China and India has become a political as well as a safety issue, with several congressional committees conducting investigations and proposing legislation.
Last year, thousands of pets were reported to have fallen ill and died after eating pet food from China that was found to have been spiked with the chemical melamine, which was apparently added to make the food appear to be of higher quality. Authorities also recalled thousands of Chinese-made toys last year that were found to contain lead-based paint.
Regarding the contaminated heparin, Woodcock said: "We still don't know whether this inadvertently got into the supply or whether it was actually added. We can't tell you where the contamination originated."
Woodcock said that since December, the FDA has received 785 reports of serious allergic reactions linked to heparin, either in products supplied by Baxter or of unknown origin. She said the number of deaths associated with heparin had risen from four to 19, some occurring as far back as January 2007. In a statement, the company that supplies raw heparin to Baxter, Scientific Protein Laboratories LLC, said it had recalled all active ingredients from China that showed signs of possible contamination. The company also said it remained unclear whether the contaminant was the cause of the reactions.
"During the call with the media, FDA speculated that the source of the adverse events may be a contaminant. It is important to note that this theory is speculation at this point, and SPL is participating actively in working with the FDA to pursue this theory as well as others," the company said in a statement.
Baxter stopped distributing heparin early last month and last week recalled all remaining heparin products. The FDA stressed that the remaining supplies of heparin, made by APP Pharmaceuticals also from Chinese sources, did not show contamination.
Baxter's statement said it found the contaminant in samples from the Chinese plant and in samples processed at its Wisconsin factory from Chinese ingredients.
"These results suggest that the root cause may be associated with the crude heparin, sourced from China, or from the subsequent processing of that product before it reaches Baxter," the firm said.
The FDA said last week that a team of inspectors had found quality- control, waste-removal and machine-cleanliness issues at the Changzhou plant. But officials said they had not made any determination about whether those factors contributed to the contamination.

"It was a nightmare for my family," said Jennifer Hsu, a graphic designer whose parents owned several Chinese restaurants in New York City in the 1970s. "Not because we used that much MSG -- although of course we used some -- but because it meant that Americans came into the restaurant with these suspicious, hostile feelings."
Even now, after "Chinese restaurant syndrome" has been thoroughly debunked (virtually all studies since then confirm that monosodium glutamate in normal concentrations has no effect on the overwhelming majority of people), the ingredient has a stigma that will not go away."

"Senate Votes For Safer Products"
"Enforcement Would Get Major Boost"
By Annys Shin Washington Post Staff Writer Friday, March 7, 2008; A01
The Senate yesterday approved the most far-reaching changes to the nation's product safety system in a generation, responding to recalls of millions of lead-laced toys that rattled consumers last year.
Lawmakers still have to resolve key differences between the Senate bill and a similar measure that passed the House in December. While the Senate version is considered by consumer advocates to be tougher, both contain provisions that would require retailers and manufacturers to be more vigilant about product safety.
The biggest change is likely to be a better-staffed Consumer Product Safety Commission, with more enforcement power. Both bills would boost funding for the agency, which had a budget of $63 million in fiscal 2007 and just less than 400 employees, fewer than half the number it had in 1980. The Senate bill, which passed by a vote of 79 to 13, would increase the budget to $106 million by 2011. The House's version would increase it to $100 million.
Both bills would provide funds to upgrade the CPSC's antiquated testing facilities. Both bills also would raise the maximum amount of money the CPSC can fine companies that fail to report product hazards immediately. Fines are now capped at $1.8 million. The House bill would raise the cap to $10 million; the Senate to $20 million.
The Senate and House measures would also effectively ban lead in all children's products, not just toys, and require toys to be tested by independent labs.
"I'm glad something is going to change. I just hope future families don't have to go through what we had to go through," said Andrew Hartung of Manalapan, N.J., whose 14-month-old daughter, Abigail, was injured last fall in a Bassettbaby crib that was later recalled.
The bill's sponsor, Sen. Mark Pryor (D-Ark.), said, "The vote is a victory for the health and safety of children."
The differences that remain involve which federal safety laws state attorneys general would be able to enforce, whether to grant whistle- blower protection to corporate employees, and which information would be included in a public database of product-safety incidents. The White House and the nation's largest manufacturers oppose giving state attorneys general too much leeway to interpret federal safety regulations, and they oppose whistle-blower protection, which they contend would encourage needless litigation.
The president has not threatened a veto.
An overhaul of the nation's product-safety system seemed a remote possibility just a year ago.
For the past decade, consumer and environmental groups had been finding lead in children's products. After a boy died in 2006 from swallowing a metal charm made of lead, the CPSC began to examine lead in children's jewelry. But until last year, the CPSC attracted little attention from lawmakers, despite regular testimony by consumer advocates about problems at the agency. Occasional pleas from industry were also futile.
Then, starting last March, a string of recalls involving toothpaste, tires and pet food containing contaminated ingredients from China caused U.S. consumers to question product safety. Public confidence in federal oversight of imports sank further in June when toymaker RC2 recalled Thomas and Friends toys for having lead paint, a toxic substance that most people thought had been banished from toys in the 1970s.
Lawmakers and the toy industry began talking about overhauling the CPSC in September after Mattel recalled more than 20 million products, including Barbie, Elmo and Dora toys, because they were coated in lead or contained small, dangerous magnets.
"It wasn't until some of these recalls began to happen relating to standards that had been in place for many years that we realized the system needed to be strengthened," said Toy Industry Association President Carter Keithley.
After years of sparsely attended congressional hearings, Nancy A. Nord, acting chairman of the CPSC, was greeted by a standing-room-only crowd at her September appearance before a Senate subcommittee. By then, retailers had begun retesting their inventory and recalls of lead-laced toys became almost daily events.
Despite a desire by both consumer groups and manufacturers to get a bill passed by year's end, negotiations over the House and Senate bills dragged on.
In early November, several Australian children fell into comas after ingesting parts of a craft toy. Doctors discovered that a chemical component in the toy metabolized into a substance used as a date-rape drug. The same toy was marketed in the United States and sickened two children.
