Today, consumers can purchase dozens of medical tests without a prescription–tests that tell them whether they are pregnant, have a urinary infection, their cholesterol is too high, and so on.

Should direct-to-consumer (DTC) genetic tests be as readily available? These are the mail-in saliva tests that tell consumers about their genetic susceptibility to Alzheimer’s disease, type 2 diabetes, heart disease and other conditions.

DTC genetic tests are different from the genetic tests that have been used for decades in prenatal and newborn screening, and more recently in predictive testing (like the BRCA test for breast cancer risk).

The difference is not the substrate being tested. In both cases, it’s DNA. Rather, it’s who owns the testing process.

For the legacy DNA tests, health professionals own the process. As per protocol, they obtain permission (informed consent) from patients before ordering the test. Then, they consult with and support the patient once the results are known.

In contrast, DTC genetic tests transfer ownership of the genetic testing process to consumers. A person can decide for herself whether to get a DTC genetic test. She doesn’t need permission from a provider, and has no obligation to share the information with her provider.

This bothers many physicians, bioethicists and consumer advocates. They point out that DTC genetic test reports can be difficult to interpret (for physicians as well, I might add, despite claims that they are universally qualified to do so). They decry the lack of regulatory oversight of testing facilities which might help assure the accuracy and reliability of the information. Furthermore, reports of “egregious…deceptive marketing” by some DTC genetic testing vendors suggest that consumers maybe harmed, they say.

These people call for regulatory oversight of DTC genetic testing. The FDA has in certain limited instances, already begun to do just that.

Physician organizations tend to support the regulation of DTC genetic testing. In particular, they favor rules that transfer ownership of DTC genetic testing to (guess who?) physicians who can then serve as custodians of the information, just as they do for the traditional genetic tests mentioned above.

Set the Data Free
I disagree. People who want access to their genetic-risk information should be free to pay their own money to obtain it, period. The only place where regulation has a role in DTC genetic testing is to assure the quality of the results being generated. That’s it.

A federal panel advised the FDA last week that menthol cigarettes are more harmful to the public health than regular cigarettes. However, it did not recommend or endorse any actions the FDA should take to act on the advice.

According to the panel, menthol cigarettes drive-up cigarette smoking rates among youth and African-Americans because its minty taste attracts people to try cigarettes and makes it harder for them to quit. In addition, its mild anesthetic properties mask the harsh taste of cigarettes. That sensation might otherwise deter some from the habit before they get hooked. The report also cites evidence that consumers believe (incorrectly) that menthol provides some health protection or medicinal benefit.

“Removal of menthol cigarettes from the marketplace would benefit public health in the United States,” the panel’s report concludes.

The panel’s official name is the Tobacco Products Scientific Advisory Committee. Its report will likely trigger a lengthy test of the FDA’s ability to promulgate and enforce restrictions on cigarettes, nicotine and menthol. The FDA will review the report and other information before deciding what to do. It has no obligation to do anything.

Reaction to the report was mixed. Some saw it as a necessary first step toward an outright ban on menthol. Others were disappointed that the advisory group shied away from recommending steps the FDA might take to deal with the problem it identified. (more…)

Nicotine replacement therapy makes it easier to quit smoking by providing a therapeutically safe fix of the chemical that makes cigarettes addictive in the first place. In the 25+ years since nicotine-laced patches, gum and lozenges became available, they have amassed a remarkable safety record. In fact thousands of people—and perhaps many more than that–have used NRT products for decades with few or no untoward effects (other than a notably thinned-out wallet). 

As a result, the FDA may soon relax the warning label verbiage affixed to NRT products. Currently, the FDA recommends that such products should be used for no longer than 12-weeks. The recommendation under consideration is that NRTs can be used for prolonged periods—perhaps indefinitely.

“There really doesn’t appear to be any great harm” with the use of NRT over long periods of time, said K. Michael Cummings, chair of the department of health behavior at the Roswell Park Cancer Institute in an interview. “You’re better off chewing gum or wearing a patch than smoking.”

Public health advocates like Cummings have petitioned the FDA for years to relax its recommendations. They received a boost from a 2009 law which empowered the FDA for the first time to regulate tobacco products. A provision in the law tasks the agency to consider relaxing the warning labels on NRT products.

Labels on NRT products advise users to taper-off on their consumption of the products over a 12-week period. These recommendations have stood since the FDA first approved nicotine gum in 1984. They were established to be consistent with the duration of NRT product utilization during clinical trials that were designed to test their efficacy, rather than scientific data regarding health risks associated with long-term NRT use.

There is no evidence that nicotine is carcinogenic in its own right, at least in humans. It may however increase cardiovascular risk because it causes mild tachycardia and mild elevations in blood pressure. (more…)

Most people know that sugary cola drinks have no nutritional benefits, promote weight gain, obesity and diabetes, and contain caffeine, a mildly addictive stimulant. Some people know these drinks contain phosphoric acid, which promotes tooth decay and bone loss, especially in females. But until last week, almost nobody knew that the artificial brown “caramel” coloring that gives cola drinks their familiar appearance contains carcinogens.

How can something as apparently benign as caramel coloring contain cancer-causing agents? Isn’t caramel coloring derived from caramel, that simple homemade treat created by melting sugar in a saucepan?

It turns out that there are several ways to create caramel coloring. The one used to create the caramel coloring found in Coca-Cola, Pepsi, and other foods involves chemical processes that include ammonia. This particular process produces so-called Caramel IV and a pair of byproducts, 2-methylimidazole and 4 methylimidazole, which have been shown to cause cancer of the liver, lung and thyroid, as well as leukemia in laboratory animals.

The disquieting news came in the form of a regulatory petition filed by the Center for Science in the Public Interest, which also called for the FDA to ban these substances from food and drinks that are consumed by US consumers. 

The petition cited studies from the National Toxicology Program which provided “clear evidence” that both substances are animal carcinogens. It also cited studies by scientists at UC Davis, which found the chemicals in several popular cola brands.

“Carcinogenic colorings have no place in the food supply, especially considering that their only function is a cosmetic one,” CSPI executive director Michael Jacobson said in a press release. “The FDA should act quickly to revoke its approval of caramel colorings made with ammonia.” (more…)

More than 70% of all medical devices that have been recalled by the FDA for safety concerns were not subjected to rigorous clinical testing before the agency approved them, according to a new study.

The study authors were Diana Zuckerman and Paul Brown from the National Research Center for Women and Families, a consumer group, and Steven Nissen, a cardiologist at Cleveland Clinic.

The authors reported that overall, the FDA recalled 113 medical devices between 2005 and 2009. Of these, 21 had been approved on the basis of rigorous clinical trial data. Eighty others had been approved under a less stringent, expedited approval process known as 510K, in which a device maker needs only to show that its new product is substantially similar to one already on the market. An additional 8 devices were exempt from FDA regulations, and 4 more were either counterfeit or classified as “other.”

Devices approved using the 510K approval process included mechanical ventilators, insulin infusion pumps, artificial hips and knees, and external cardiac defibrillators. The more rigorous process is typically reserved for life-supporting devices like implanted cardiac defibrillators. In the latter process, device makers must sponsor trials designed to prove their products are safe and effective.

Last summer, the FDA announced it was implementing some steps to “strengthen” the 510K process, but it deferred on a complete overhau pending the release of a report on the matter by the Institute of Medicine. The report is due later this year. (more…)
