Princess Health and The More Things Stay the Same - More Apparently Adulterated Heparin, This Time from Chinese Ruminants. Princessiccia

Princess Health and The More Things Stay the Same - More Apparently Adulterated Heparin, This Time from Chinese Ruminants. Princessiccia

The story of the contaminated heparin just will not go away.  We first wrote about it in 2008 (see first post here, most related posts here, and the longer summary at the end of this post.)

Quick Summary

Baxter International imported the "active pharmaceutical ingredient" (API) of heparin, that is, in plainer language, the drug itself, from China. That API was then sold, with some minor processing, as a Baxter International product with a Baxter International label. The drug came from a sketchy supply chain that Baxter did not directly supervise, apparently originating in small "workshops" operating under primitive and unsanitary conditions without any meaningful inspection or supervision by the company, the Chinese government, or the FDA. The heparin proved to have been adulterated with over-sulfated chondroitin sulfate (OSCS), and many patients who received got seriously ill or died. While there have been investigations of how the adulteration adversely affected patients, to date, there have been no publicly reported investigations of how the OSCS got into the heparin, and who should have been responsible for overseeing the purity and safety of the product. Despite the facts that clearly patients died from receiving this adulterated drug, no individual has yet suffered any negative consequence for what amounted to poisoning of patients with a brand-name but adulterated pharmaceutical product.

Here We Go Again

At the end of March, 2016, per Bloomberg,

Heparin tainted with unauthorized Chinese-made ingredients may be on the market in the U.S. and the Food and Drug Administration hasn�t moved swiftly enough to prevent it, according to a congressional probe nearly a decade after hundreds of deaths were linked to sullied batches of the blood-thinning drug.

This possible contamination is different from the earlier one, when Chinese producers made crude heparin containing a deadly chemical. They may be using cow and sheep intestines to produce the raw material for heparin that is supposed to be derived only from the intestinal membranes of pigs, according to a letter the House Energy and Commerce Committee sent Tuesday to the FDA. The agency has known about the risky practice since 2007, around the time it discovered the chemically enhanced crude heparin, the panel said.

The FDA didn�t react early on 'to credible evidence of non-porcine contamination of the Chinese heparin supply,' according to the letter, only putting out testing guidelines for pharmaceutical companies in 2012. Even after the tragedy of the chemically soiled heparin, the committee said, 'loopholes and exemptions that permit part of the Chinese drug supply chain to operate outside government scrutiny still remain.'

The committee charged that nothing much as changed since the 2008 episode of deadly heparin made from Chinese pigs

The letter from the House committee said the FDA dropped the ball on many fronts and may have allowed unsafe blood thinners to remain on the market longer than necessary. Regulators didn�t properly or widely enough share information and didn�t follow up on leads about tainted heparin from other governments, according to the letter. Agency investigators failed to inform others about dodgy crude heparin makers, the panel said. It also said the FDA didn�t follow up on concerns that heparin with the chemical was recycled after the poison was removed and may have entered the U.S. market. The claims are based on documents that Baxter, Scientific Protein and FDA provided the committee as well as interviews with FDA employees, according to footnotes in the letter.

Also, efforts to investigate the 2008 problem seem to have failed,

The chemical, oversulfated chondroitin sulfate, was connected to 246 deaths and sickened hundreds of people who took the blood-thinning medicine, the FDA said at the time. Regulators never found at what point in the chain in China that the drug, sold in the U.S. by Baxter International Inc., was corrupted. The FDA closed its initial criminal investigation after it became difficult to obtain evidence in China, though it has since re-opened a related inquiry, according to the House committee. Baxter, which recalled its heparin in 2008, hasn�t sold the anticoagulant since. It said at the time it was alarmed that the contamination appeared to have been deliberate, but had no proof of how it happened.


Now the problem appears to be more bovine. It appears that French regulators first noted the problem of imported heparin derived from Chinese cows.

The French National Agency for Medicines and Health Products Safety called non-pig blending a 'critical' violation in an inspection report released in February. France cited China�s Dongying Tiandong Pharmaceutical Co. for making heparin with ruminant DNA, which includes cows and sheep. Dongying is registered with the FDA as a manufacturer of active ingredients and isn�t on the agency�s list of companies banned from importing to the U.S.

Yet, the FDA

considers heparin adulterated if it contains oversulfated chondroitin sulfate or non-pig material, according to an FDA document for the pharmaceutical industry on monitoring heparin quality. Material from cows could pose a risk because of possible contamination with mad cow disease.
Oddly enough, the Bloomberg article did not mention any criticism by the committee of the US based manufacturers who outsourced their heparin production to China.

Outsourcing Continues Unabated


In 2012 we noted that outsourcing by big multinational drug companies based in the US and other developed countries of active pharmaceutical ingredient (API) production to dubious manufacturers based in countries with much less robust regulation was continuing.  I wrote then

To put it more directly, most so called pharmaceutical companies in the US and other developed countries have outsourced the actual manufacturing of drugs. Thus, most companies that appear to be pharmaceutical manufacturing companies are really just pharmaceutical marketing and development companies. (And not so much the latter, look here:  Light DW, Lexchin JR. Pharmaceutical R&D; what do we get for all that money? Brit Med J 2012; 345: 22-25.  Link here.) Pharmaceutical companies appear to be abandoning their core essence, but are content to market drugs  under their logos without telling the patients who take them the real source of these products.  This would appear to be a big scandal, but one that stays curiously anechoic.

In 2016, outsourcing of drugs by big multinational corporations with prestigious names seems to be continuing at a rapid pace.  Per Bloomberg,

The U.S. depends heavily on China for medicine. Along with India, the country is one of the top two producers of base ingredients for drugs in the world, according to the National Academies of Sciences, Engineering, and Medicine.

There is still no clear way for US patients or doctors to identify outsourced medicines, and efforts to better regulate them seem feeble. Thus the danger that patients may be getting ineffective, adulterated, even deadly outsourced medicine in bottles with the logos of big, famous pharmaceutical companies seems to be ongoing.

The More Things Stay the Same

In 2012, we wrote

I have yet to see any discussion with pharmaceutical executives about why their companies hardly make drugs anymore. In the absence of such discussion, I can only speculate that most likely, this is first a product of financialization. Drug company executives, like most organizational leaders, have fallen under the spell that says their only goal should be to increase short-term revenues. It may be cheaper to buy drugs from perhaps dodgy outsourced suppliers rather than manufacturing them them themselves. Continuing stories like those above, and that of the contaminated Chinese heparin suggest that these outsourced drugs are cheap for a reason. It appears that to save money short-term, pharmaceutical executives may be abandoning their most central mission, to provide pure, unadulterated drugs.

The continuing story of outsourced pharmaceutical manufacturing provides yet more evidence that current management dogma may be literally toxic. Once again, I suggest that true health care reform requires leadership of health care organization who put patients' and the public's health ahead of short-term revenue (and the personal enrichment that may result).

It is likely that a number of policy changes will be needed to reduce the threats posed by contaminated or adulterated outsourced pharmaceuticals.  There is one simple step that ought to be taken quickly to at least make the problem more transparent.  In the US, most manufactured products have a label disclosing the country of origin.  In parallel with that, all pharmaceutical containers, and all pharmaceutical labels and marketing materials ought to disclose the country in which the active pharmaceutical ingredient was manufactured, and the name and location of the company responsible for that manufacture.

There seems to be no need to rewrite or update this.

The fact that this problem has been known for 2008 year, but not clearly addressed, shows the pitiful state of American health care dysfunction.  But those with vested interests in preserving the current system remain fat and happy, like the pigs of China.

 Appendix - Heparin Case Summary

- We have posted several times, recently here about the tragic case of suddenly allergenic heparin. Although heparin, an intravenous biologic anti-coagulant, has been in use for over 70 years, serious allergic reactions to it had heretofore been rare. Starting late in 2007, hundreds of such reactions, and 21 deaths were reported in the US after intravenous heparin infusions.All the heparin related to these events in the US was made by Baxter International.

- We then learned that although the heparin carried the Baxter label, it was not really made by Baxter. The company had outsourced production of the active ingredient to a long, and ultimately mysterious supply chain. Baxter got the active ingredient from a US company, Scientific Protein Laboratories LLC, which in turn obtained it from a factory in China operated by Changzhou SPL, which in turn was owned by Scientific Protein Laboratories and by Changzhou Techpool Pharmaceutical Co. Changzhou SPL, in turn, got it from several consolidators or wholesalers, who in turn got it from numerous small, unidentified "workshops," which seemed to produce the product in often primitive and unsanitary conditions. None of the stops in the Chinese supply chain had apparently been inspected by the US Food and Drug Administration nor its Chinese counterpart. (See posts here and here.)

- We found out that the Baxter International labelled heparin was contaminated with over-sulfated chondroitin sulfate, a substance not found in nature, but which mimics heparin according to the simple laboratory tests used in the Chinese facilities to check incoming heparin. (See post here.) Further testing revealed that the contamination seemed to have taken place in China prior to the provision of the heparin to Changzhou SPL. (See post here.) It is not clear whether Baxter International or Scientific Protein Laboratories had inspected most of the steps in the supply chain, or even knew what went on there.

- The Baxter and Scientific Protein Laboratories CEOs did not seem aware of where they got the heparin on which the Baxter International label was eventually affixed. But one report in the New York Times alleged that Scientific Protein Laboratories would not pay enough for heparin to satisfy any sources other than the small "workshops."

- Leaders of all organizations involved, Baxter International, Scientific Protein Laboratories, Changzhou SPL, the Chinese government, and the US Food and Drug Administration, and the US Congress assigned blame to each other, but none took individual or organizational responsibility. (See post here.)  Note that SPL was recently bought out and taken private, making its current leadership even less transparent (see post here).  A 2010 inspection of an SPL facility by the FDA revealed ongoing manufacturing problems (see post here).

- Researchers (who turned out to have financial ties to a company which is developing an anti-coagulant drug that could compete with the heparin made by Baxter International) investigated the biological mechanisms by which the contamination of the heparin lead to adverse effects, but no one investigated further how the contamination occurred, or who was responsible. (See post here.)

- Hundreds of lawsuits against Baxter have now been filed, so far without resolution. (See post here.)  Efforts to make documents to be used in these cases public so far have not succeeded (see post here).

- A government report which attracted little attention warned of the dangers of pharmaceutical ingredients made in China and subject to virtually no oversight. (See post here.)

-  Despite requests from the US, the Chinese government did not investigate the production of the heparin that lead to the deaths (see post here.)

-  In February, 2011, a congressional investigation of the case was announced, but results were unavailable until now (see above)

-  In June, 2011, a jury returned the first verdict in a civil case about the contaminated heparin, awarding money from Baxter International and Scientific Protein Laboratories to the estate of a man who apparently died due to tainted heparin (see post here).

Princess Health and Guest Post: Scholarly Mad Libs and Peer-less Reviews. Princessiccia

Princess Health and Guest Post: Scholarly Mad Libs and Peer-less Reviews. Princessiccia

Health Care Renewal presents a guest post by Marjorie Lazoff, MD, a Board certified internist with a clinical background in academic emergency medicine.  She is currently a full time freelance editor and independent consultant specializing in evidence-based clinical content and medical informatics.

On December 17, 2014, Scientific American published an investigative report by journalist Charles Seife documenting a new and curious form of scholarly publication fraud, For Sale: �Your Name Here� in a Prestigious Science Journal. As an editor and supporter of evidence-based medicine I am both appalled by, and sympathetic to, how such widespread fraud could take place unnoticed.

Seife describes how he discovered the doctored writings:

The dubious papers aren't easy to spot. Taken individually each research article seems legitimate. But in an investigation by Scientific American that analyzed the language used in more than 100 scientific articles we found evidence of some worrisome patterns�signs of what appears to be an attempt to game the peer-review system on an industrial scale�

�This is not a simple case of plagiarism. Many seemingly independent research teams have been plagiarizing the same passage. An article in PLOS ONE may eventually lead to 'our better, comprehensive understanding' of the association between mutations in the XRCC1 gene and thyroid cancer risk. Another in the International Journal of Cancer (published by Wiley) might eventually lead to 'our better, comprehensive understanding' of the association between mutations in the XPA gene and cancer risk�and so on. Sometimes there are minor variations in the wording but in more than a dozen articles we found almost identical language with different genes and diseases seemingly plunked into the paragraph, like an esoteric version of Mad Libs, the parlor game in which participants fill in missing words in a passage.

Another example virtually eliminates the likelihood of coincidence:

There is no such thing as a 'Beggers funnel plot'�the proliferation of 'Begger's' tests [were discovered] by accident. While looking for trends in medical journal articles, papers [were found] that had almost identical titles, similar choices in graphics and the same quirky errors, such as 'Begger's funnel plot.'

Seife�s investigative reporting revealed that China was the source of most of his �fill-in-the-blanks� research. Further,

Much of the funding for these suspect papers comes from the Chinese government. Of the first 100 papers identified by Scientific American [and listed at the close of his article], 24 had received funding from the National Natural Science Foundation of China (NSFC), a governmental funding agency roughly equivalent to the U.S.'s National Science Foundation. Another 17 acknowledged grants from other government sources.

Seife suspects that most research probably began as legitimate work without intent to deceive, but somewhere an author or service was added to help ensure publication through the necessarily arduous manuscript review process.

The culprit?

A quick Internet search uncovers outfits that offer to arrange, for a fee, authorship of papers to be published in peer-reviewed outlets. They seem to cater to researchers looking for a quick and dirty way of getting a publication in a prestigious international scientific journal.

Seife�s investigation goes undercover, 60 Minutes style:

In November Scientific American asked a Chinese-speaking reporter to contact MedChina, which offers dozens of scientific 'topics for sale' and scientific journal 'article transfer' agreements. Posing as a person shopping for a scientific authorship, the reporter spoke with a MedChina representative who explained that the papers were already more or less accepted to peer-reviewed journals; apparently, all that was needed was a little editing and revising. The price depends, in part, on the impact factor of the target journal and whether the paper is experimental or meta-analytic. In this case, the MedChina rep offered authorship of a meta-analysis linking a protein to papillary thyroid cancer slated to be published in a journal with an impact factor of 3.353. The cost: 93,000 RMB�about $15,000.

Finally, the corrosive effect of this particular fraud on scientific and medical publication is real:

Publishers at the moment are fighting an uphill battle. 'Without insider information it's very difficult to police this,' Clinical Endocrinology's Bevan says. CE and its publisher, Wiley, are trying to close loopholes in the editorial process to flag suspicious late changes in authorship and other irregularities. 'You have to accept that people are submitting things in good faith and honesty,' Bevan says.

That is the essential threat. Now that a number of companies have figured out how to make money off of scientific misconduct, that presumption of honesty is in danger of becoming an anachronism.

Were this the only threat currently facing research journals today! Last month, Retraction Watch published an article describing a known and partially-related problem: fake peer reviews, in this case involving 50 BioMed Central papers. In the above-described article, Seife referred to this BioMed Central discovery; he was able to examine 6 of these titles and found that all were from Chinese authors, and shared style and subject matter to other �paper mill-written� meta-analyses.

Retraction Watch agrees:

It would seem that a third party, perhaps marketing services helping authors have papers accepted, was involved.

Problems with peer review are longstanding editorial fodder. For a description of another recent peer review scam, this one involving authors hijacking researchers� identities, see the article also written by Retraction Watch editors and published last month in Nature.

On Friday, in response to requests by several publishers, The Committee on Publication Ethics (COPE) posted a statement on inappropriate manipulation of peer review processes 

While there are a number of well-established reputable agencies offering manuscript-preparation services to authors, investigations at several journals suggests that some agencies are selling services, ranging from authorship of pre-written manuscripts to providing fabricated contact details for peer reviewers during the submission process and then supplying reviews from these fabricated addresses. Some of these peer reviewer accounts have the names of seemingly real researchers but with email addresses that differ from those from their institutions or associated with their previous publications, others appear to be completely fictitious.

COPE recommends, among other things, the retraction of articles based solely on fraudulent reviews. Retraction Watch�s announcement earlier today of a MacArthur Foundation grant to help fund a comprehensive and freely available database of retractions could not have come at a better time!

Seife and Retraction Watch have documented new forms of published research fraud among third world researchers. Certainly the solution is not for editors and readers to suspect all papers from specific countries; there are ample instances of research fraud emanating from English-speaking researchers and top U.S. institutions. Research from around the world is critically important, particularly although not exclusively in the basic sciences, emerging infectious disease, and public health/epidemiology. Now that it has been identified, a common screening procedure for manuscripts at a journal can be adjusted to filter out this new form of plagiarism.

Sadly, it seems to me that fraudulent research of all types can flourish within a perfect storm of circumstances and factors: the globalization of science and medicine encourages non-or-limited English-speaking researchers to publish (or perish) in the highest impact English language journals; the proliferation of open-access wannabes, hybrids of every color and degree of sincerity, and other money-over-science journals and companies that rip off desperate and na�ve researchers; a complicated, time-consuming and often author-unfriendly manuscript submission process; and journal editors who struggle with limited staffing and resources, necessarily arduous editorial processes, and the pressure of increasing numbers of worthy manuscripts deserving to reach the scientific and medical communities in near-real time. Research fraud is particularly destructive given traditional publishing�s ongoing struggle to survive the transformational Electronic Age; the pervasive if not perverse marketing of pharma, medical device companies, and self-promoting individuals and institutions using �unbiased� research; and today�s bizarrely anti-science culture.

Health Care Renewal is wonderful at calling out intentionally perpetrated health care events whose importance and implications can be debated, depending on one�s perspective and personal values. Here, I think, we have the reverse: there is near unanimity over the need to prevent fraudulent papers of any type from contaminating our research databases, as best as is humanly and technologically possible. There is also near unanimity among quality medical journals throughout the world, and internationally respected editor and publisher groups, to confront and solve these problems. The enemy identified by HCR is not always unrestrained greed or maliciousness. Sometimes, as in this case, the enemy is a cacophony of small circumstances and extraneous factors that could, if left unattended, invisibly erode something we all hold dear.

Without ongoing attention and support from the entire medical and science communities, we risk the progressive erosion of our essential, venerable research database, until it finally becomes too contaminated for even our most talented editors to heal.
