The blood thinners included in this announcement include Arixtra (fondaparinux sodium) Solution for subcutaneous injection; Fragmin (dalteparin sodium injection) for Subcutaneous Use; Innohep (tinzaparin sodium) injection; and Lovenox (enoxaparin sodium) injection for subcutaneous and intravenous use.

The new warning states that epidural or spinal hematomas may occur in patients who are anticoagulated with low molecular weight heparins (LMWH) or heparinoids and are receiving neuraxial anesthesia or undergoing spinal puncture. These hematomas may result in long-term or permanent paralysis. Health care professionals are asked to consider these risks when scheduling patients for spinal procedures.

Factors that can increase the risk of developing epidural or spinal hematomas in these patients include:

• Use of indwelling epidural catheters
• Concomitant use of other drugs that affect hemostasis, such as non-steroidal anti-inflammatory drugs (NSAIDs), platelet inhibitors, other anticoagulants.
• A history of traumatic or repeated epidural or spinal punctures
• A history of spinal deformity or spinal surgery

Health care providers are encouraged to monitor patients frequently for signs and symptoms of neurological impairment. If neurological compromise is noted, urgent treatment is necessary. Benefits and risks should be weighed before neuraxial intervention in patients anticoagulated or to be anticoagulated for thromboprophylaxis.

Investigators now know that the pre-filled heparin and saline syringe Fullerton used was part of a contaminated lot that has since been linked to at least four deaths and 162 illnesses. And that lot could have and should have been prevented from being shipped to hospitals by the Food and Drug Administration (FDA).

Months before the syringes were shipped out, the FDA received reports about debris in syringes filled with heparin and saline distributed by drug manufacturer AM2PAT, yet the agency didn’t follow up on the complaints until 2007 after the reports of deaths and illnesses following use of the syringes. Reports from 2007 inspections show that investigators found a “gummy brown” substance on the syringe-filling machine. The plant was closed in January 2008.

Consumer advocates say the FDA should have acted faster and more aggressively to prevent the contamination of the pre-filled syringes at AM2PAT. Congress, too, has been critical of the agency for not properly or adequately inspecting food and drugs that are distributed to American hospitals and health care centers, and are pushing for better inspection standards within the agency.

Bian Zhenijia, director of the drug safety supervision department of the State Food and Drug Administration (SFDA), urged companies to be more responsible when dealing with foreign suppliers.

“The problem lies in the fact that some overseas companies have an implicit deal with underground factories or illegal manufacturers in China, so the product involved has problems,” Bian said at a press conference.

China’s pharmaceutical industry is poorly regulated and several deaths and illnesses have been blamed on contaminated medications produced there. Last year, heparin manufactured in China was linked to more than 80 deaths and hundreds of illnesses in the United States. The blood thinner was later found to have been contaminated with a heparin-mimicking substance called oversulfated chondroitin sulfate, or OSCS. Heparin is derived from pig intestines, which are often produced by unregistered China businesses.

“I do not agree with what the foreign media say. The Chinese government has always paid a lot of attention to cracking down on fake drugs,” Bian told a news conference. “If the international community can give us information on fake drugs, we will resolutely investigate. There is no ambiguity about this.”

More than 300,000 cases of unlicensed drugs and medical products were distributed in 2007, according to SFDA.

Announcement of the deaths and illness at Beebe Medical Center in Lewes, Delaware, raised immediate concern at the hospital, which promptly notified the FDA and Baxter. The incidents were far too similar to the 2007 heparin scandal in which more than 80 Americans died and hundreds more became ill after receiving doses of Baxter’s heparin. An investigation found some lots of heparin manufactured in Baxter’s China factory were contaminated with a heparin-like substance called over-sulfated chondroitin sulfate, or OSCS.

Both Baxter and the FDA investigated the Beebe incidents. Earlier this week Baxter announced its investigation found no OSCS contaminate in the heparin supplied to Beebe. It also said the heparin used by Beebe was manufactured in its Ohio plant, not the China facility.

But the mystery about the deaths and illness at Beebe still remains. A Baxter spokesperson said that following the national guidelines for drugs like heparin does not guarantee that there will be no problems with the medication.

“Even when those protocols are followed, bleeding at a site, including intercranial bleeding, can occur – especially in high-risk patients, which is an established side effect of all anticoagulant therapies,” said Erin Gardiner with Baxter. “Our responsibility is for the safety of the product.”

Two deaths and one illness earlier this month following the injection of heparin in patients at a Lewes, Delaware, hospital sent chills through the nation. Could this be a repeat of the deadly contamination that harmed so many in 2007? The vials of heparin were traced back to Baxter, however these doses were manufactured in Ohio, not China, the drug maker contends.

Last year’s OSCS contaminant caused victims to suffer severely low blood pressure. This new reaction involves intracranial bleeding. Investigations by both Baxter and the Food and Drug Administration (FDA) followed and early findings indicate there is no trace of OSCS in the heparin used. Now Baxter says it is confident that the events at the Delaware hospital were “isolated, institution-specific issues, unrelated to the quality of Baxter’s heparin premix product,” a Baxter spokesperson told the Reuters news organization.

According to Baxter, it obtained samples from the lot in question as well as lots produced before and after the lot in question. Testing on those lots confirmed that the product’s formulation was within specifications and met all requirements. The FDA backed up Baxter’s contention: “We don’t see a quality problem with the product,” an FDA spokesperson said.

All three incidences occurred at the Beebe Medical Center in Lewes, Delaware, and all three were given heparin supplied by Baxter, the same drug company at the center of last year’s contaminated heparin scandal. That heparin, which killed more than 80 people and injured hundreds more, was manufactured in China. The latest batch was manufactured in Ohio.

The heparin in question involves premixed intravenous bags of heparin whereas the previous heparin, which was later found to have been contaminated with a heparin-mimicing substance called over-sulfated chondroitin sulfate (OSCS), involved vials of the medicine and drug-coated medical devices.

The symptoms suffered from the newest victims involved intracranial bleeding; the previous deaths and illnesses were caused by severely low blood pressure. Immediately following the adverse reactions, the hospital contacted Baxter, which immediately contacted the FDA.

Both Baxter and the FDA sent medical teams to Delaware and the FDA took samples of the heparin for testing. “As far as we can determine at this point, it appears to be an isolated incident,” says FDA spokewoman Karen Riley.

Baxter has tested for but not found the contaminant OSCS to be in the batches of heparin taken from Beebe Medical Center. Baxter insists the heparin used on the patients who became ill at Beebe was not manufactured in China but in North America.

Anticoagulants are often administered to patients before undergoing some surgeries and medical procedures to reduce the risk of life-threatening blood clots. Lovenox has been touted as an effective replacement for the blood thinner heparin in patients undergoing abdominal surgery.

Heparin carries a laundry list of side effects such as nausea, vomiting, abdominal pain, diarrhea and low blood pressure. Concerns about heparin flooded the media last year with cases of accidental overdoes and shipments of tainted batches of the blood thinner imported from China. Both incidences caused patients serious injury or death.

The contaminated heparin scandal in particular created an urgency among consumers, the medical community and pharmaceutical companies to find safer alternatives to the commonly used blood thinner.

Momenta chief executive officer Craig A. Wheeler said in the conference call that the FDA continues to review its Abbreviated New Drug Application (ANDA) process for M-Enoxaprin. ANDA is the FDA’s Center for Drug Evaluation and Research Office of Generic Drugs review and ultimate approval process of a generic drug.

Once approved, an applicant may manufacture and market the generic drug product to provide a safe, effective, low cost alternative to the American public. “We are in regular communication with the agency and responding to their questions as they arise,” Wheeler said.

Wheeler referred to the “global contamination issue” with the heparin supply and the FDA’s plant inspections of Chinese suppliers of heparin, adding that the companies who supply heparin to Momenta’s partner distributor Sandoz for the manufacture of M-Enoxaprin have all been inspected by the FDA.

While the company has no indication that the inspections raised concerns with the FDA, Wheeler said “Any disruption in the heparin supply has the potential to impact our supply chain.” As a result, the company will diversify its sources of heparin and closely monitor the supply chain.

Momenta hopes to launch M-Enoxaparin in 2009 provided the ANDA is readily approved by the FDA.

Rep. Joe Barton

The FDA has previously claimed the raw heparin originated from a manufacturing company in China and was purposefully contaminated with a man-made chemical, over-sulfated chondroitin sulfate, OSCS. The Chinese government disagrees.

Barton, a ranking member of the House Energy and Commerce Committee, has long championed the effort to resolve the heparin scandal by scrutinizing the FDA’s investigation into the case and the subsequent recall. He has previously argued that the agency misrepresented deaths tied to the heparin and didn’t thoroughly investigate the matter. He also has demanded answers on why the FDA took six months to seize lots of the contaminated heparin from an Ohio agency that still had the tainted drug in stock.

In his latest inquiry, Barton wants to know if the FDA has tracked the contamination back to the source. He also asked what action the Chinese government has taken in the matter and whether anyone in China has been held accountable.

Products imported from China have been in the spotlight in recent years as reports of more tainted foods, drugs and toys have entered the U.S. and injured people. The FDA has been working to expand its inspections of foreign imports in part by opening offices overseas. The first of these offices opened late last year in China.

It wasn’t until then that Martin learned the syringe he had used on his young son was part of a recalled batch that was found to have been contaminated at the manufacturing plant AM2PAT. The tainted syringes killed five people and sickened at least 100 more before the Angier plant was closed. The company’s “clean room” was found to be a frightful mess.

Last month, two AM2PAT managers pleaded guilty to federal fraud and a warrant is out for AM2PAT president Dushyant Patel, who is still at large.

Knowledge of the recall did little to put Martin’s mind at ease. He wants answers from the company, the distributor of the syringes, and the Food and Drug Administration (FDA).

“I just felt, why? Why didn’t somebody stop this?” he told media. “Not only did they hand me a loaded gun, they enabled me to pull the trigger on my own son.”

An FDA warning letter to the plant in 2005 reported no major safety violations. However, an FDA spokesperson says in August 2007 the company began producing the syringes at a “dramatic rate” and that was when quality began to slip.

The FDA was notified by the Centers for Disease Control and Prevention about the adverse events reported, and within five days the FDA had closed down the plant for manufacturing violations. The FDA also contends that “evidence of a casual link between the AM2PAT product” and the infections was “never conclusively established.”

The FDA’s claims don’t sit well with Martin, who says he will pursue legal action.

Blood tends to pool in the atrial chamber of individuals with atrial fibrillation, which can lead to clotting and an increased risk for strokes. Patients with atrial fibrillation are generally treated with blood thinners to help prevent blood clots from forming.

However, blood thinners like heparin can cause serious bleeding episodes and allergic reactions. Alternatives to long-term use of blood thinners has many cardiologists taking notice.

“The findings from this clinical trial are very impressive,” said Dr. Gregg C. Fonarow, professor of cardiology at the University of California, Los Angeles. “Treatment with this novel device will be very attractive and provide patients with atrial fibrillation effective, long-term protection from stroke and systemic embolization without the bleeding risks associated with (blood thinners).”

The PROTECT-AF Trial, which involved 707 patients with a type of atrial fibrillation, showed that patients who had the device had a 32 percent lower risk of stroke and cardiovascular death compared with those on blood thinners. The study also found fewer complications with the implanted device compared to the use of blood thinners.

A Food and Drug Administration (FDA) advisory panel will meet in April to consider the sale of the device in the United States.

The label changes include modifications to the Warnings, Precautions and Adverse Reactions sections of Heparin Sodium in 5% Dextrose Injection and Heparin Sodium in 0.9 % Sodium Chloride Injection.

The labeling changes in part were spurred by the much-publicized overdosing of actor Dennis Quaid’s newborn twins, who nearly died in 2007 when they were accidentally given 1,000 times the intended dose of the blood thinner. The Quaid’s case is just one of many cases where health care workers claimed to have confused high-dose and low-dose heparin. Some argue that the two bottles can be easily confused.

Heparin is generally used when a patient – adult or infant – receives fluids through a central line to prevent a blood clot from forming, which could eventually grow and break off and kill a patient. But if the blood is too thin, it puts the patient at risk for life-threatening bleeding or hemorrhages, including in the brain.

Heparin has seen its fair share of the spotlight lately. Last year more than 80 Americans died and hundreds more were sickened after receiving doses of heparin made at Baxter International’s China plant. An investigation found that lots made in that plant were contaminated with oversulfated chondroitin sulfate (OSCS). The contaminant can cause serious allergic reactions and even death.

Sharfstein made headlines in 2007 when he convinced the FDA to restrict the use of over-the-counter children’s cough and cold medicines based on evidence they can cause serious health complications and even death in children.

If there is one government agency that needs overhauling, it is clearly the FDA. The agency has been under scrutiny for the past few years over contaminated food and drug products that have harmed and even killed Americans.

The agency is still feeling the repercussions from the tainted heparin scandal. Last year more than 80 Americans died and several more were made seriously ill after receiving injections of specific batches of the blood thinner that had been manufactured in a China plant. Those batches were found to have been contaminated with oversulfated chondroitin sulfate (OSCS), a contaminant that mimics heparin but can cause serious allergic reactions.

Following the revelation, the FDA admitted that it simply did not have manpower to properly inspect foreign food and drug manufacturing plants. Since then the FDA has taken measures to step up its inspections by opening field offices overseas. The first three offices opened late last year in China.

The FDA employs more than 11,000 employees and an annual operating budget of $2 billion.

Last March, after more than 100 people died and hundreds more were sickened after being given the tainted heparin, an investigation found that heparin manufactured in Baxter’s China plant had been contaminated with oversulfated chondroitin sulfate (OSCS). OSCS mimics heparin and can cost substantially less to produce – $9 compared to $900. However, OSCS can cause serious allergic reactions which can lead to death.

The lawsuit states, “The recalled heparin was adulterated, misbranded, defective, unreasonably dangerous and unfit for its intended uses. Baxter placed tens of thousands of patients, including the Plaintiffs, at unnecessary risk of serious injury and/or death.”

It also claims Baxter wrongfully allowed the heparin to be placed on the market and “breached its express warranties that heparin had no dangerous side effects and that its ingredients were manufactured in a plant in accordance with FDA regulations,” according to the report.

The six-count suit seeks a judgment of more than $300,000 plus costs and other relief.

AM2PAT is now the subject of a criminal investigation. Federal investigators say the company was so focused on making profits that it did not conduct necessary safety tests and instead covered up the matter by falsifying reports to make it appear those tests had been conducted.

Earlier this week, workers at the plant pleaded guilty for their roles in the scandal and were sentenced to four years in prison. The company’s president, Dushyant Patel, faces numerous charges but has apparently fled to his native country India. If convicted, he faces up to 95 years in prison.

According to reports, the FDA received complaints that there were “orange specks,” or “yellow sediment” floating in the unopened syringes, or that the medicine inside appeared “muddy brown.” Despite the reports, which are recorded as early as November 2005, the FDA didn’t follow up on the complaints until 22 months later.

Food and drug manufacturing plants should be inspected by the FDA every two years, but many plants, such as AM2PAT have received site visits about every five years, according to a report from the Government Accountability Office. The report also shows that between 2002 and 2007, FDA inspectors visited only about 25 percent of the 5,616 registered plants each year.

SOURCE: Heparin Recall › FDA knew of tainted syringes two years before inspecting plant

Earlier this week two former workers at the plant, plant manager Aniruddha Patel and quality control director Ravindra Kumar Sharma, were sentenced in federal court to more than four years in prison for allowing the tainted drugs into hospitals and clinics in Colorado, Florida, Illinois and Texas. Last week, the company’s chief executive, Dushyant Patel, was indicted on 10 charges for fraud and selling adulterated medical devices. A warrant is out for his arrest.

The drugs were not produced at the plant, but were put into the syringes and shipped to the hospitals and clinics from there. According to Patel, the company recalled the syringes a year ago after federal officials began investigating the outbreak.

“Citizens in this country trust that producers of medical devices aren’t lying when they say that have adequately tested a given product,” said U.S. Attorney George Holding to the Associated Press. “As we’ve seen in this case, such lies can literally mean the difference between life and death.”

Ralph Sell of Lincoln, Nebraska, says that his wife Alice was undergoing cancer treatments in December 2007 when a syringe contaminated with Serratia marcescens, a bacteria that can cause serious injury or death, was used on her. She suffered high blood pressure, disorientation and sepsis. She died a year later at the age of 82 of “acute respiratory failure.” It has not yet been determined if the contaminated syringe may have led to her death.

Sell filed suit against Baxter International as well as its subsidiary Baxter Healthcare Corp., B. Braun Medical Inc., and AM2 PAT Inc, also known as Sierra Prefilled. A spokesperson for Baxter says the company has no role in the lawsuit, as it does not sell prefilled saline syringes. AM2 PAT did recall saline prefilled syringes in December 2007 and January 2008 because some of the syringes were tainted with the bacteria.

Baxter currently faces numerous lawsuits stemming from a 2008 recall of the blood thinner heparin. Batches of the company’s heparin manufactured in China were found to have been contaminated with over-sulfated chondroitin sulfate (OSCS). The tainted heparin is believed to have contributed to the deaths of more than 80 Americans and caused serious illnesses in hundreds more.

Sell’s lawsuit against the companies seeks unspecified damages and payment for medical costs.

The new standards were proposed by scientists with U.S. Pharmacopeia, a nonprofit public health group that sets standards for the quality, purity, strength and consistency of medicines. A spokesperson with the group says the new standards are the best as scientifically possible at this time.

The revisions for testing the popular blood thinner were first requested by the FDA when the contaminant was identified in March. The changes are expected to go into effect on August 1 and include three identification tests and screening for organic impurities.

Baxter was one of the leading manufactures of heparin, producing half of the injectable heparin sold in the U.S. and generating about $30 million in sales each year. Baxter stopped sales of heparin last year and has yet to resume selling the anti-coagulant. The company is facing numerous lawsuits from families affected by the tainted heparin.

Heparin is a blood thinner used to prevent blood clots. It is often given before surgery and during treatments such as kidney dialysis to prevent clotting. In appropriate use or overdosing can be fatal.

This week, Zelenka – known to some as the “heparin murderer” – was sentenced to life for the murder of seven people, according to Czech media outlet Noviny. Police have pinned another three murders on him as well as one attempted murder.

Police are looking into 14 other cases in which they suspect murder or attempted murder. Another ten cases were closed after police couldn’t find proof that a crime was committed. Even if authorities link more murders and attempted murders to Zelenka, he will not be prosecuted as he currently will serve the highest sentence for the crimes he already has been found guilty of.

Zelenka admitted to all crimes but during the trial said he only remembers administering heparin to five patients. He says police coerced him into admitting to additional crimes.

Such is the case with the blood thinner heparin, which last year was the focus of much scrutiny when 80 Americans died and hundreds more were sickened after receiving doses of heparin manufactured in China. An investigation found that batches of heparin manufactured in Baxter International’s China plant had been contaminated with oversulfated chondroitin sulfate (OSCS). OSCS mimics the appearance of heparin but cause adverse reactions and even death.

Years ago most drugs were manufactured in the U.S., but over the years those operations have moved overseas – in particular, to Asia – where labor, construction, regulatory and environmental costs are lower. The FDA also inspects domestic plants far more often than foreign ones, which also adds to pharmaceutical companies’ production costs.

Following the heparin contamination last year, the FDA admitted that it was not sufficiently staffed to inspect all foreign offices. Thus, the agency has since begun to set up offices in foreign countries. To date, offices have been placed in China and India. The FDA also launched a voluntary two-year “Secure Supply Chain” pilot project to help promote the safety of drugs and active drug ingredients made outside the U.S.

Last year the FDA announced it would place more than 60 food and drug regulators worldwide in an effort to keep unsafe drugs out of the country. Late last year the first offices opened in China, a country whose products have made headlines over the past several months for harming hundreds of thousands of people around the globe.

Aside from lead paint on toys, faulty cribs, tainted pet food and contaminated milk, China was also the site where investigators found a drug manufacturing company had contaminated batches of the blood thinner heparin with oversulfated chondroitin sulfate (OSCS). OSCS mimics the appearance of heparin but can cause adverse reactions and even death.

Before the contaminate was detected, the OSCS-laced heparin was imported into the United States, where it was administered to patients. The tainted heparin killed more than 80 people and sickened hundreds more.

The FDA reports that India is the fourth largest exporter of drugs and biologics into the U.S., according to Med Page Today.

The FDA also announced last week that it will launch a voluntary two-year “Secure Supply Chain” pilot project to help promote the safety of drugs and active drug ingredients made outside the U.S. The program is designed to assist the FDA in its efforts to prevent the importation of drugs that do not comply with applicable FDA requirements.

The Quaids also sued Baxter Healthcare Corp. over the packaging and labeling of its high-dose and low-dose heparins, arguing the two bottles are easily confused. Other cases of heparin overdose have been reported and linked in part to the confusing packaging. The Quaid’s lawsuit against Baxter was dismissed on jurisdictional grounds because the event occurred in California.

Baxter was no stranger to the spotlight in 2008, facing numerous lawsuits most notably for the tainted heparin scandal earlier in the year. More than 80 Americans died and hundreds more were sickened after receiving doses of heparin made at Baxter China plant. An investigation found that lots made in that plant were contaminated with over-sulfated chondroitin sulfate (OSCS). The contaminant can cause serious allergic reactions and even death. The FDA issued a recall on batches of Baxter’s heparin.

According to news reports, the Quaid-Cedars-Siani case indicates that Baxter may also sue Cedars-Siani for improperly administering the blood thinner to several patients at the hospital, including the Quaid’s newborn twins.

Joyce Ann Osteen filed the suit in St. Clair County, Illinois, and claims Baxer purposefully added a contaminant, over-sulfated chondroitin sulfate, or OSCS, to heparin manufactured in its China plant. The tainted heparin was distributed to the U.S., where hundreds of allergic reactions occurred. More than 80 people died and hundreds more were sickened by the tainted heparin before an investigation led to a recall of batches of heparin manufactured at Baxter’s China facility. The FDA later issued an announcement saying that the contaminant was an inexpensive and unapproved ingredient that mimics heparin.

OSCS costs only $9 to produce compared to $900 for heparin, the suit contends.

“The recalled heparin was adulterated, misbranded, defective, unreasonably dangerous and unfit for its intended uses,” the suit states. “Baxter placed tens of thousands of patients, including the Plaintiff at unnecessarily risk of serious injury and/or death.”

The suit states Osteen and the class members who purchased the heparin “suffered actual damages as a proximate result of Baxter Healthcare Corp.’s deception in that they were deprived of the benefit of their bargain.” According to the complaint, Osteen is asking the court to certify the complaint as class action. She also is seeking damages of less than $74,999 per plaintiff or class member.

In early December, the FDA announced that it had received information about the Innohep in Renal Insufficiency Study (IRIS) that was stopped in February because of an interim finding of increased mortality in elderly patients.

As a result, in July, the company revised the prescribing information to restrict the use of Innohep in patients 90 years of age and older. However, preliminary data from IRIS suggests that the increased risk of mortality is not only limited to patients in that age range. Study results suggest that compared to unfractionated heparin, Innohep increases the risk of death for patients 70 years and older with renal insufficiency and deep vein thrombosis (DVT), pulmonary embolism (PE), or both. The FDA suggested health care professionals consider the use of alternative treatments for patients older than 70 years of age with those conditions.

The FDA says it anticipates submission of the final IRIS study report sometime in January and will complete its review soon thereafter. Additional regulatory actions as appropriate will be considered after thorough review of all applicable data from the manufacturer of Innohep.

Researchers at Beaumont Hospital in Royal Oak, Michigan, have developed a treatment protocol to quickly and effectively diagnose brain bleeds in patients who are on blood thinners and bump their heads. The study treated 105 patients under the new protocol. As a result, diagnosis of brain bleeds occurred in half the time and treatments were started faster. Under this new system, death rate also was reduced from 40 percent to 11 percent.

The protocol includes rapid initial evaluation by a doctor or nurse, a CT scan performed on a priority basis, a blood transfusion and administration of vitamin K to help the blood clot, according to the report.

“These seem like relatively simple steps, but when combined they become a powerful force that helps save lives,” Emax Health quoted Greg Howells, M.D., director of Trauma Surgery. When the head bumps occur, many people can appear fine even if the injury is causing the brain to bleed. Previous studies have shown that people on blood thinners are four times more likely to die from a blow to the head than those not on blood thinners.

As a result of the study, more than 40 other hospitals across the country have asked about Beaumont’s treatment protocol for people on blood thinners who bump their heads.

Blood thinners are routinely given to patients before certain types of surgery and treatments such as kidney dialysis to prevent blood clots from forming. Clots that do not naturally dissolve can travel through the blood stream and end up in the brain, causing a stroke, or in the lungs, causing a pulmonary embolism. Blood clots, also known as thrombosis, is a serious problem affecting nearly a million Americans each year and killing nearly 300,000 annually.

Two more common types of blood thinners are heparin and warfarin. Heparin is administered intravenously, requiring medical supervision, whereas warfarin is given orally. Both drugs have been used medically for decades. Both have side effects that doctors and patients find bothersome, including easy bruising, excessive bleeding, lower back pain, weakness or light-headedness, and flu-like symptoms. Thus physicians are eager to find safer alternatives.

Furthermore, heparin has been in the spotlight continuously over the past several months for confusing labeling that has resulted from overdoses that have sickened and killed patients, as well as batches of contaminated heparin that made its way into hospitals, causing more illnesses and deaths in patients who received the bad lots.

Last year, heparin was thrust into the spotlight after more than 80 patients who had received the blood thinner died and hundreds more became ill. An investigation to the adverse reactions found that batches of heparin manufactured in Baxter International’s China plant were contaminated with over-sulfated chondroitin sulfate (OSCS). That discovery spurred the FDA to recall lots of heparin made by Baxter International.

“Perhaps the most surprising fact that emerged in our three months of reporting on contaminated heparin ingredients from China: The U.S. government has little ability to know whether the drugs we are taking are safe or not,” Eisner points out.

Last month, the FDA vowed to step up its efforts to oversee quality control of imported foods and drugs by opening offices in foreign countries. Its first offices opened in China. The FDA plans to place more than 60 food and drug regulators worldwide over the next several months. However, the agency says it will take more than a decade to adequately inspect all foreign drug manufacturing plants.

“As a result,” Eisner writes, “doctors must take it on faith that the medicines they are prescribing are exactly what they are supposed to be.”

Franke Leon Isom of Webster, Ken., died Dec. 14, 2007, a day after he was given heparin during treatment at Woodland Dialysis Clinic in Elizabethtown. Attorneys argue that Isom received part of the 55,000 gallons of heparin that was contaminated with over-sulfated chondroitin sulfate (OSCS).

Earlier this year, a series of deaths and adverse allergic reactions from patients who had received doses of heparin led to an investigation that linked the reactions to lots of heparin made at Baxter International’s China plant. Further review found the heparin had been contaminated with OSCS during manufacturing in China. Shortly thereafter, the FDA ordered a recall. The tainted heparin is blamed for more than 240 deaths worldwide and caused hundreds more people to fall ill from allergic reactions to OSCS, such as hypotension.

The lawsuit, filed on the behalf of Isom’s estate, is one of 50 similar civil tort claims against Scientific Protein Laboratories and Baxter International, according to the news report. Attorneys argue that recalled lots of heparin were still found on hospital shelves months after the recall went into effect.

Heparin from another company, APP Pharmaceuticals Inc., wasn’t considered a problem, though in a letter to Congress in October, the FDA said one patient taking the APP heparin had a severe reaction that may have led to his death, according to the news report. APP responded in a letter to the congressman’s staff that the company had thoroughly reviewed the case and did not believe the patient’s death was a result of contaminated heparin.

Rep. Barton wants to know why the FDA has “no information” about whether that patient’s death was caused by the same contaminant – over-sulfated chondroitin sulfate – as was found in Baxter International heparin.

Rep. Barton has been on the FDA’s case for more than a month, questioning the agency’s handling of the heparin recall, claiming it misrepresented deaths tied to the product , arguing that it didn’t thoroughly investigate the matter, and ordering answers on why the agency took six months to seize lots of contaminated heparin from an Ohio agency.

Earlier this year, the FDA recalled lots of heparin manufactured in a Baxter International Chinese plant after batches were found to have been contaminated with over-sulfated chondroitin sulfate. The FDA recall was the result of an investigation into the deaths of more than 80 people and illnesses of hundreds more people after receiving doses of heparin.

CNN Money reports that the recall process is voluntary. Companies are not required to immediately comply with the FDA’s request, however FDA inspectors reportedly told Celsus Laboratories in April that its recall efforts were insufficient, and a month later followed up in a letter to the company expressing the same concerns. Last month, the FDA seized 11 contaminated lots of heparin from Celsus Laboratories.

The FDA won’t elaborate on why Celsus Laboratories’ efforts were less than satisfactory, saying its investigation into the matter is still ongoing. The agency did say that on occasion it sends safety officers to companies to conduct “100 percent effectiveness checks” to ensure they are taking proper measures to destroy the recalled products.

Rep. Joe Barton, a member of the House Energy and Commerce Committee, has been following the heparin situation and, last month, asked the Government Accountability Office to look into the matter. The congressman also wrote a letter to the FDA commissioner saying he wants to know when the agency first decided it was appropriate to seize heparin from Celsus Laboratories. He also asked for a list of all individuals involved in the decision to seize the heparin.

At the time the study was stopped, 350 patients had completed a 90 days of follow-up. Twenty-three out of 176 patients who received tinzaparin died, compared to nine out of 174 who received unfractionated heparin. The FDA says it sees no clear pattern as to the cause of death nor do the deaths appear to be related to either over-dosing or under-dosing of an anti-coagulant.

In July, the company revised the prescribing information to restrict the use of Innohep in patients 90 years of age and older. However, preliminary data from IRIS suggests that the increased risk of mortality is not only limited to patients in that age range. Study results suggest that compared to unfractionated heparin, Innohep increases the risk of death for patients 70 years and older with renal insufficiency and deep vein thrombosis (DVT), pulmonary embolism (PE), or both. The FDA suggests health care professionals consider the use of alternative treatments for patients older than 70 years of age with those conditions.

The FDA has requested that the labeling for Innohep be revised to better describe the overall results of IRIS. The agency anticipates final IRIS results in January 2009, and will complete its review at that time.

The victim, who had complained of chest pains for three weeks, was admitted to Hawke’s Bay Hospital in January. Doctors diagnosed him with unstable angina and administered Enoxaparin, a low molecular weight heparin manufactured by Sanofi-Aventis. A half-hour later he was diagnosed with acute lateral myocardial infraction, or a heart attack, and was given another dose of heparin. Within hours, the overdose caused his gums to bleed and his brain to hemorrhage. He died early the next morning.

A cardiologist’s review said that the lack of communication among hospital staff and a delay in seeking advice from the medical registrar was likely the cause of the overdose, which lead to the large, intracerebral hemorrhage that brought on the man’s death. Heparin should not be given to patients less than 12 hours after Enoxaparin.

The coroner’s report did not lay blame on any one medical staff member, however it did show areas for improvement in the treatment. The Hawke’s Bay District Health Board followed up with an extensive review in an effort to improve patient safety and communication among dempartments. As a result, Hawke’s Bay Hospital has implemented treatment protocols for heart attacks among hospital staff and more emphasis is being placed on improving communication between the emergency department and coronary care staff.

Batches of heparin were recalled by the FDA earlier this year after lots manufactured in China were found to have been contaminated with over-sulfated chondroitin sulfate. The investigation and subsequent recall followed reports of more than 80 deaths and thousands more illnesses of patients who had received doses of heparin from the lots in question.

Rep. Joe Barton, R-Texas, last week pointed out that the FDA made conflicting statements to the public and Congress about the number of deaths caused by the blood thinner. Last May, the FDA said it completed a review of three deaths linked to the tainted heparin. Last month, the FDA told Congress that only two deaths were possibly linked to the incident and the third was “unassessable.”

Baxter International, the company involved in the tainted heparin incident, conducted its own investigation and determined that the contaminant was likely not the cause of death in any of the three cases mentioned by the FDA. Baxter’s investigators reviewed patient medical records, interviewed pharmacists and nurses, and visited a hospital where one of the patients had gone before dying.

The FDA came under fire over the tainted heparin scandal after admitting it did not properly inspect Baxter’s China facility. Inspecting all foreign drug manufacturing facilities could take as long as 13 years, the agency has reported. This week the FDA opened its first foreign office, located in Beijing, China, as part of a push to place more than 60 food and drug regulators worldwide to provide guidance on U.S. food and drug quality standards.

During dialysis, patients are hooked up to a machine that draws out the blood through tubing. Since blood tends to clot when it moves through the tubing, patients routinely are given the blood thinner heparin to prevent clotting.

One week before Christmas, after two months of regular dialysis, Bonnie fell ill with diarrhea, vomiting and soon, severe pain in her chest and abdomen. She was rushed to intensive care and within days was unconscious and on a breathing tube. The doctors said there was no more she could do. Leroy’s wife was suddenly and unexpectedly dead.

As Leroy tried to cope with the loss of his longtime wife, their son Randy suddenly became sick with the same symptoms. He was born with the same genetic kidney disease as his mother, and was receiving regular dialysis treatments. His wife, a dialysis nurse, tried desperately to revive him but it was no use. Randy died just three weeks after his mother.

Both Bonnie and Randy were victims of tainted heparin, batches of the drug manufactured in China and later found to have been contaminated with over-sulfated chondroitin sulfate (OSCS). The Hubleys were just two of more than 80 deaths caused by the contaminated heparin. Several hundreds more were sickened by the drug before the FDA recalled batches made in the Baxter International Chinese plant. To date, the FDA has recalled 13 different contaminated medical products containing heparin from various companies.

Last week had U.S. Marshals raided Celsus Laboratories Inc., and found 11 lots of the tainted blood thinner that had not been removed. The recalls and FDA crackdowns come too late for the Hubley family and for the hundreds of families affected by the contaminated heparin. We need to be assured that the contaminated heparin is removed for good so that no more lives are in jeopardy.

The FDA ordered U.S. Marshals to seize the products today. Mike Chappell, acting associate commissioner for regulatory affairs for the FDA is quoted as saying, “This action will help prevent this contaminated heparin from finding its way into the marketplace.”

Earlier this year, heparin manufactured by Baxter International, Inc., was found to be contaminated with OSCS. That heparin also contained components manufactured in China, which is believed to be the source of the contamination. The Baxter contamination led to hundreds of injuries and 81 deaths.

The FDA news release states that the agency has initiated 13 recalls of multiple contaminated medical products containing heparin from several companies, to date this year.

Information in the news release indicates the Celsus heparin entered the United States before the establishment of FDA import controls for the drug, and was reviewed by the FDA after it was processed at Celsus as a part of the agency’s process to implement the controls.

The release also indicates that the FDA knew about the contamination in April 2008, when it warned Celsus Laboratories during an inspection that the company’s actions to notify customers about the contaminant were insufficient. The FDA says it warned Celsus again that it needed to step up its efforts to notify customers about the potential hazard in a May 8, 2008 letter. Finally, today the FDA seized the contaminated product from the lab.

Manufacturers who may have purchased heparin from Celsus are urged to contact the company immediately to make sure they are not using any heparin from the since-seized lots. The product does not meet acceptable quality standards, the release says.

Septic shock is a serious condition that can cause multiple organ failure and death. It is the main cause of mortality in intensive care units (ICU), with a mortality rate of up to 40 percent.

There is only one drug other than antibiotics approved to treat septic shock, and that drug costs about $10,000 per patient. But two Canadian intensive care physicians, Dr. Ryan Zarychanski and Dr. Anand Kumar, who studied the effect of the blood thinner heparin on ICU patients between 1989 and 2005, found that patients with severe sepsis who were given heparin lowered their risk of death by 30 percent. Heparin, a generic drug, costs less than $10.

The research involved nearly 1,400 Winnipeg ICU patients with septic shock. Six hundred and ninety-five of the patients received heparin for suspected heart attacks or blood clots. Another 695 did not. The study found that there were 15 percent fewer deaths among patients who had received heparin.

Heparin for the treatment of septic shock is controversial, says Zarychanski, because it refutes the belief that expensive pharmaceuticals are the best treatment option. Thus, companies are unlikely to invest in researching it for other benefits as there is little or no profit in it.

But the safety of drugs, like heparin that is imported into the U.S. from countries like China, still hangs in the balance. It is just as important to find new treatments for less expensive drugs as it is to ensure the safety of all drugs.

The active ingredient in heparin is derived from pig intestines and the demand for the drug has become so great that the domestic pig population cannot meet the demand. To meet the immediate need, pharmaceutical companies have turned to China, which has three times the pig population.

But importing drugs from China has raised some serious concerns. Earlier this year, 81 people died and hundreds more were sickened after receiving doses of heparin, which was later found to have been contaminated in a Chinese manufacturing plant.

As a result, scientists are eagerly working to develop a synthetic version of heparin that could be made in U.S. labs, thus preventing future scares. In August, we told you about Rensselaer Polytechnic Institute’s Robert Linhardt, who had just announced that after years of work his research team appeared to have successfully devised a synthetic heparin.

Linhardt and his team continue to forge ahead with the synthetic drug, according to the Scientific American. The challenge, however, is that it is hard to mass produce. It took a year for Linhardt and his team to produce 100 milligrams of the synthetic version, which pales in comparison to the more than 100 metric tons of heparin needed to meet the world’s demand for just one year.

Linhardt hopes to have a gram of synthetic heparin – or enough to give 100 doses to mice to start animal trials – within a year. Far more of the synthetic drug would be needed for clinical testing on patients, presenting a further challenge. Cost could become another issue, as heparin made from pig intestines costs only about 20 cents per dose and making the synthetic version a feasible business would take years and a huge investment.

However, Linhardt says mass production of the synthetic heparin would have benefits that far outweigh the negatives: “The future is one that will be short continuously of heparin,” he was quoted in Scientific American. “Which means any adulterations of the heparin (imported by the U.S.), we’re going to have to live with—or catch.”

Early last year, more than 80 people died and thousands more were sickened after receiving the blood thinner heparin. It was later found that specific lots had been contaminated at a manufacturing plant in China.

Even more were harmed recently when 50,000 children were sickened by milk from China that was contaminated by melamine, a product used in the manufacturing of plastics, fertilizer, paint and adhesives that can be lethal to infants.

This, just a year after parents around the world were urged to dig through their children’s toy boxes in search of Barbies, Batman action figures and Thomas the Train cars that was found to be contaminated with high levels of lead paint. The Mattel toys – which included several different products and numbered more than 21 million worldwide – were made in China. Lead paint can be especially damaging to the nervous system, cause hearing loss, stunt growth and delay development. It also can cause reproductive problems in adult men and women.

Now there is a new recall on a product made in China. The U.S. Consumer Product Safety Commission (CPSC) and Delta Enterprise Corp., just announced a voluntary recall of 985,000 drop-side cribs because of a risk of entrapment and suffocation to infants. The CPSC is aware of the death of an 8-month-old who became entrapped and suffocated, two entrapments, and nine disengagement incidents.

The recall includes selected Delta crib models manufactured in Taiwan or Indonesia between 1995 and 2005, and one model made in 2007. The cribs were sold at major retailers between 2000 and 2007. Delta cribs currently sold at retailers on not included in the recall.

Parents and caregivers are urged to stop using the cribs immediately and call Delta at (800) 816-5304 or go to www.cribrecallcenter.com for a free repair kit.

The blood thinner heparin made news recently when the FDA recalled batches of heparin after more than 80 people died and several others became ill after receiving heparin. It was later determined that heparin made by Baxter International was contaminated in the company’s Chinese manufacturing facility.

While heparin is considered an effective treatment for preventing blood clots and is widely used, it must be injected, which makes long-term therapy difficult. The new drugs would be taken by mouth, which would make dosing easier and eliminate the need for laboratory monitoring.

Heparins garner about $700 million in annual sales, with Sanofi-Aventis’ Lovenox making up nearly two-thirds of the world’s share of the drug. Pfizer’s Fragmin and GlaxoSmithKline’s Fraxiparine account for 6.3 and 5.9 of sales, respectively. Vitamin K Antagonists are responsible for more than $6 billion in sales worldwide, with Bristol-Myers Squibb’s Coumadin, Barr’s Warfarin and Eisai’s Warfarin owning slightly more than half the market’s share.

Three of the five companies are in the late phases of clinical testing, two of which already have been approved in Canada and are awaiting approval in the United States. Two other companies’ drugs have been approved for short-term use in Europe.

Italian researches carefully selected 700 of the “lowest risk” patients to participate in the trial. This included patients with single blockages of a heart artery, currently taking two clot-preventing medications such as aspirin and thienopyridine, and with no immediate danger of heart attack.

The study found that the incidence of heart damage and bleeding events were lower in the patients who participated in the study, and there was a lower risk of death, heart attack or blood vessel problems.

According to the American Heart Association, the artery-opening procedure, formerly called percutaneous coronary interventions, is a procedure used to treat patients with diseased arteries of the heart. For example, chest pain caused by a build-up of fats, cholesterol and other substances from the blood that can reduce blood flow to a near trickle or heart attack caused by a large blood clot that completely blocks the artery.

The Italian study cautioned that using no heparin is a bold step and one that should be taken only after serious consideration and evaluation of the patient’s health.

While more work is needed to confirm the results, some researches applaud efforts to move medical innovations like this forward. This is especially welcome news considering the recent contaminated heparin scare that killed more than 80 Americans and sickened hundreds more.

Last month I told you that California Rep. Harry Waxman, who serves as head of the House Oversight and Government Reform Committee, raised concerns that items outlined on the FDA’s 2007 priorities list appeared to prioritize industry desires over consumer protection.

This, just months after more than 80 American deaths were linked to tainted heparin that was made in Baxter International Inc.’s facility in China. FDA officials later acknowledged they had not inspected that facility and claimed they had insufficient staff and financial resources to regularly inspect overseas manufacturers.

Today, the Washington Post reported that the FDA has hired a public relations company it improve its image. However, in yet another PR blunder, the story reports that the way it hired the company may also be raising eyebrows.

The story suggests that the FDA may have violated government contracting rules by not holding a bidding competition for a $300,000 contract hiring a firm to create “a lasting positive public image for the agency.” Instead it made a deal with Alaska Newspapers Inc., (ANI) which is exempt from having to compete for federal work because it qualifies for special set-asides. ANI agreed to funnel all the work to the FDA’s agency of choice, Qorvis Communications. Apparently the FDA’s new PR head, Mildred Cooper, had connections to the firm and wanted to use it.

The FDA cancelled its contract with ANI/Qorvis Communications after the Washington Post’s story ran. And while the FDA claims it never meant to do anything questionable during the selection process, this latest blunder certainly hasn’t helped the organization’s public image.

In recent weeks, according to a Reuters/The Epoch Times, three children and more than 6,000 infants have become ill after consuming infant formula contaminated with toxic melamine, according to Reuters/The Epoch Times.

Let’s recap some of the other made-in-China scares that plagued the United States, highlighted in the story:

More than 200 cats and dogs died and thousands more became ill when melamine was discovered in China-made pet foods. As a result, more than 100 brands of pet food were recalled in North America in March 2007.

A month later, the U.S. National Highway Traffic Safety Administration (NHTSA) recalled 450,000 tires made by China’s second-largest tire maker, Hangzhou Zhongce Rubber Co. Ltd., for an insufficient or missing gum strip.

A year ago, the world’s largest toymaker, Mattel, recalled more than 18 million small, powerfully magnetic toys that were made in China because, if swallowed, could cause serious injury. Two weeks later, the company recalled 1.5 million toys because of concerns over lead paint.

According to the story, other Chinese-made products such as toothpaste, cough syrup, eggs, lipsticks, dumplings and fish also were cited as causing possible health risks to individuals in China and other parts of the world.

According to the report, aides for both candidates said that recent health scares had dampened their candidates’ enthusiasm of reimportation. Neither candidate has abandoned the prospect; however, they admit it has become a more controversial subject.

Other countries, such as Canada, have government price controls that keep prescription drug costs down, making reimportation of foreign drugs a far more attractive option, especially for those who spend hundreds and thousands of dollars on prescriptions each year. While several U.S. bills on reimportation have been proposed, none have become law, the report stated.

Organizations representing pharmaceutical companies such as the Generic Pharmaceutical Association (GPhA), oppose the practice, arguing that there is no guarantee drugs or goods from other countries would be safe, Reuters/Boston Globe reported.

Earlier this year, American deaths were linked to tainted heparin that was made in Baxter International Inc.’s facility in China. According to news report, FDA officials acknowledged they had not inspected that facility and claimed they had insufficient staff and financial resources to regularly inspect overseas manufacturers.

Linhardt was among the researchers who discovered the source of tainted heparin that was responsible for at least 149 deaths since the beginning of 2007. Manufacturer Baxter International, which supplies about half of the heparin used in the U.S., recalled its supplies of heparin made in China after more than 80 patients suffered serious allergic reactions and death following its use.

According to a report by Bloomberg News Service, Chinese pig farms that provide source material for heparin are not monitored by the U.S. Food & Drug Administration, which increases the risk for contamination. Continued use of traditional heparin products manufactured in these facilities leaves the door open for another contamination event, Linhardt says in the Bloomberg report.

In addition to Baxter’s product, a smaller scale contamination problem was reported with the Lovenox heparin medicine manufactured by Sanofi-Aventis, according to a report by Reuters.

Linhardt presented his team’s synthetic heparin results at the recent American Chemical Society meeting, according to Reuters, where he told those in attendance that today’s heparin manufacturing methods are “simply unsafe.”

Scientists are working on creating larger quantities of the synthetic heparin, which Linhardt hopes will reach human clinical trials in five years, Reuters reports.
