Vitamin D May Help Patients Survive Cancer

November 11th, 2009

From ABCNews:

When Joanna Fuchs was diagnosed with colon cancer last year, a blood test revealed she was severely deficient in vitamin D.

“I was obviously very concerned and very worried,” Fuchs said.

So, too, was her husband, Dr. Charles Fuchs of the Dana Farber Cancer Institute, who is the senior author of a study published today that found colon cancer patients deficient in vitamin D were almost twice as likely to die over a 10-year period than patients with healthy levels of the nutrient.

“These findings make considerable sense,” Dr. Fuchs said, “because in the laboratory we find that vitamin D reduces the growth of colon cancer cells, prevents its spread to other organs, and actually reduces the growth of blood vessels to these tumors.”

Fuchs’ work is just the latest in a wave of new studies on vitamin D. Vitamin D deficiency has been linked to a greater risk of autoimmune diseases, including type 1 diabetes, multiple sclerosis and rheumatoid arthritis. It has also been linked to a doubling of heart attack risk among men, a 73 percent greater risk of dying from breast cancer, and more frequent asthma attacks among children.

“Vitamin D seems to be very helpful in making your immune system do what it is supposed to do,” Dr. Tanya Edwards, director of Integrative Medicine at the Cleveland Clinic.

The government recommends getting 200 to 600 international units of vitamin D a day. But those levels were set 11 years ago, primarily to keep bones healthy. To prevent other diseases, many researchers now say more is needed.

Most people used to get all the vitamin D they needed from the sun. But with Americans now using more sunscreens, more often  or just staying out of the sun  more people are becoming deficient in this nutrient.

The solution could be taking a daily supplement. But doctors recommend patients first get a blood test to determine just how deficient they may be.

That’s what Joanna Fuchs did. And now, with a daily vitamin D pill, she hopes to remain cancer-free.

Statins + coenzyme Q10 may benefit heart failure patients

November 4th, 2009

From OliofSpices.com:

WUHAN CITY, CHINA. There is now growing evidence that oxidative stress and inflammation are involved in chronic heart failure. Statin drugs such as atorvastatin, simvastatin and pravastatin have recently been shown to posses anti-inflammatory properties and coenzyme Q10 is a powerful antioxidant and essential for cardiac mitochondrial energy production. Unfortunately, statin drugs reduce the level of coenzyme Q10, sometimes to the point of fostering muscle-related problems (myopathies) like rhabdomyolysis.

A team of Chinese researchers at Wuhan University has now come up with the idea of combining the statin drug atorvastatin (Lipitor) with coenzyme Q10 in the treatment of patients with congestive heart failure. They conducted a clinical trial in which heart failure patients on standard treatment were randomized into receiving atorvastatin, coenzyme Q10, atorvastatin + Q10, or a placebo. At the end of the 6-month treatment period the following changes were observed:

* The level of the inflammatory marker C-reactive protein (CRP) had dropped from 5.5 mg/L (0.55 mg/dL) to 2.0 mg/L in the atorvastatin + coenzyme Q10 group. Levels of the inflammatory marker tumor necrotic factor alpha and the oxidative stress marker malondialdehyde also dropped significantly in the atorvastatin + Q10 group.

* Left ventricular ejection fraction had increased from 30% to 43% in the atorvastatin + Q10 group.

* No significant changes were observed in the control group.

NAC, An Important Supplement

October 14th, 2009

N-Acetyl Cysteine

Sulfur is an essential mineral in the body. You may know it as a “rotten egg smell” or hydrogen sulfide. Various sulfur-containing substances in the body include thiamin (vitamin B-1), biotin (vitamin B-7), alpha lipoic acid, S-adenosyl methionine (SAMe), methylsulfonylmethane (MSM), insulin, glutathione, homocysteine, and four amino acids — methionine, cysteine, cystine, and taurine (1).

The focus of this article is cysteine, a non-essential amino acid made from methionine in the liver. In the production of cysteine, methionine is converted to SAMe, which is then converted to homocysteine. Finally homocysteine reacts with serine to form cysteine. This process involves several nutrients. Dietary deficiency of methionine, vitamin B-6, vitamin B-12, SAMe and folic acid may decrease the production of cysteine. Cystine is an amino acid that contains two cysteine molecules joined together (1).

Cysteine is also found in most high-protein foods including pork, chicken, turkey, duck, luncheon meat, eggs, milk, whey protein, ricotta, cottage cheese, and yogurt, as well as red peppers, garlic, onions, broccoli, Brussels sprouts, oats, granola, wheat germ (1).

N-acetylcysteine or NAC is formed by replacing a hydrogen atom on cysteine with an acetyl group (CH3 CO). Current thinking is that NAC supplements are broken down in the gastro-intestinal tract and then reassembled inside cells. NAC has two primary functions in the body. First, it acts as an antioxidant which protects cells from free radical damage. Much of this function is due to the fact that NAC is a key constituent of glutathione which is composed of three amino acids — cysteine, glutamic acid, and glycine. Glutathione is found in all human tissues, with the highest concentrations found in the liver and eyes. As a potent antioxidant, glutathione protects tissues from the damaging effects of free radicals. The antioxidant activity of glutathione is attributed specifically to the presence of cysteine in the compound . The second function of NAC supports detoxification especially in the liver (2).

These two functions form the basis for the long list of clinical applications of NAC.

Foresman discusses 12: depression; bi-polar affective disorder; schizophrenia; addiction/gambling; neural protection/Alzheimer’s; chronic fatigue syndrome/fibromyalgia; irritable bowel syndrome/leaky gut; kidney protection; fertility in men and women; high altitude sickness; bronchitis, COPD, and chronic sinusitis; as well as reduction of homocysteine and Lp(a) (3).

The Thorne Research Monograph on NAC documents nine clinical uses: Sjogren’s syndrome; smoking toxicity; influenza; hepatitis C; myoclonus epilepsy; HIV infection;
cancer/chemoprevention; acetaminophen (Tylenol®) poisoning; and heavy metal (mercury, lead, copper, gold, silver) chelation (4).

A recent study looked at the use of NAC in the treatment of bi-polar disorder. “Treatment-resistant subthreshold depression is a major problem in bipolar disorder. Both depression and bipolar disorder are complicated by glutathione depletion. Australian researchers hypothesized that treatment with N-acetyl cysteine (NAC), a safe, orally bioavailable precursor of glutathione, may improve the depressive component of bipolar disorder. A randomized, double-blind, multicenter, placebo-controlled study of 75 individuals with bipolar disorder in the maintenance phase were treated with NAC (1 g twice daily) [in addition] to usual medication over 24 weeks, with a 4-week washout. The two primary outcomes were the Montgomery Asberg Depression Rating Scale (MADRS) and time to a mood episode. Secondary outcomes included the Bipolar Depression Rating Scale and 11 other ratings of clinical status, quality of life, and functioning.

“NAC treatment caused a significant improvement on the MADRS and most secondary scales at end point. Benefit was evident by 8 weeks on the Global Assessment of Functioning Scale and Social and Occupational Functioning Assessment Scale and at 20 weeks on the MADRS. Improvements were lost after washout. There was no effect of NAC on time to a mood episode and no significant between-group differences in adverse events. Researchers concluded that NAC appears a safe and effective augmentation strategy for depressive symptoms in bipolar disorder” (5).
In women who are prone to frequent miscarriages, it has been suggested pregnancy could be associated with a state of oxidative stress that could initiate a cascade of changes that may lead to miscarriages. Because NAC is a powerful antioxidant, researchers set out to determine whether it can suppress the oxidative stress in pregnancy and whether it could stop miscarriages in women with unexplained recurrent pregnancy loss (RPL). Eighty patients with a history of RPL were treated with 0.6 grams of NAC plus 500 micrograms/day of folic acid. This group of patients was compared to an aged-matched group of 86 patients treated with 500 micrograms/day of folic acid, but without NAC.
Results of this study done in Egypt indicated that “NAC plus folic acid compared with folic acid alone significantly increased the rate of continuation of a living pregnancy up to and beyond 20 weeks. NAC plus folic acid was associated with a significant increase in the take-home baby rate as compared with folic acid alone and that NAC is well-tolerated and could be a potentially effective treatment in patients with unexplained RPL” (6).

Dietary Supplements’ Safety Amounts to ‘Roulette,’ Doctor Says

October 12th, 2009

Dr. Perlmutter’s comment:
As you read this article, consider the fact that according to the American Medical Association more than 70,000 Americans die each year as a concequence of taking pharmaceutical medications “appropriately.”

From Bloomberg.com:

Consumers who take dietary supplements promising weight loss, increased strength or improved sexual performance may be playing “American roulette” with their health, said a Harvard Medical School doctor who urged stricter regulation of the products.

The U.S. Food and Drug Administration has identified about 140 contaminated products such as weight-loss pills that may cause high blood pressure, seizures, heart attacks or strokes, and body-building products that may cause liver injury and kidney failure from undeclared ingredients, said Pieter Cohen, a professor of medicine at Harvard Medical School in Boston. Current law allows dietary supplements to be sold without clearance from the FDA as long as they aren’t advertised as preventing, treating or curing disease.

About 114 million people, or half the U.S. adult population, take dietary supplements including vitamins, minerals and herbs, and sales of the treatments reached almost $24 billion in 2007, according to a report from the Government Accountability Office in March.

“Instead of pulling the trigger of a revolver at our head, we’re swallowing unknown substances that could have life- threatening effects,” said Cohen, whose article appears online today in the New England Journal of Medicine. “Selecting a dietary supplement is our version of spinning the cylinder of the revolver.”

Consumers should avoid products advertised as body- altering, Cohen said. Doctors should ask patients if they are taking supplements, particularly if they can’t easily diagnose symptoms.

‘What’s Inside’

“We have no idea what’s inside dietary supplements because the regulatory framework is so weak, they are not being approved by any government agency and there’s no proof of safety,” said Cohen, who also is an internist at Cambridge Health Alliance, in Cambridge, Massachusetts, in a telephone interview yesterday. “Without changing the regulatory framework, I don’t think it’s possible to make dietary supplements safer.”

As of next June, all dietary supplement manufacturers must follow new manufacturing practices that establish industry procedures for quality control and ensure that companies produce properly labeled supplements, said Andrew Shao, vice president of scientific and regulatory affairs for the Council for Responsible Nutrition, a trade association for dietary supplement manufacturers and ingredient makers.

‘Outliers’

“The majority of the dietary supplement industry is compliant, however we do feel that for the few outliers in the industry, the minority of the industry, we do very much endorse stepped up enforcement by the FDA,” he said yesterday in a telephone interview. “There is no FDA-regulated product that is immune completely to these kinds of problems. The majority of dietary supplement products are well made, are safe and there are no reasons for consumers who use supplements to change their behavior.”

Since 2007, the manufacturers have been required to notify the FDA of supplement-related deaths, hospitalizations and significant disabilities. Most of the 50,000 adverse events that the FDA estimates occur each year, including those that are mild and moderate, remain unreported, according to the GAO report released in March.

Approval Not Needed

“Consumers and health care providers should be aware that manufacturers and distributors do not need FDA approval to sell their dietary supplements,” Margaret Hamburg, the FDA commissioner, said yesterday in an e-mail. “This means that FDA does not keep a list of manufacturers, distributors or the dietary supplement products they sell.”

Manufacturers have the primary responsibility under the law to make sure their products are safe, Hamburg said. The law places the burden on the agency to demonstrate safety problems exist before acting. Reporting adverse events isn’t mandatory for consumers or health care providers and it’s important for consumers to be informed about the products they’re buying, she said.

The FDA warned yesterday that dietary supplements containing silver may cause permanent discoloration of the skin or mucous membrane. Large amounts of silver may quickly turn the skin, gums or nails or eyes shades of gray or blue, according to the advisory.

Colloidal silver, or metal particles suspended in liquid, is often marketed as an alternative to antibiotics or to treat diseases such as diabetes, HIV and cancer, according to the National Center for Complementary and Alternative Medicine.

Advisory Warning

Under current law, manufacturers of supplements must list all product ingredients on the label.

In July the FDA also issued a consumer advisory warning to avoid body-building products with labels that say the supplements contain steroids or steroid-like substances. That same month the U.S. Department of Justice filed a complaint against three New Jersey companies alleging they manufactured their dietary supplements and protein powders under filthy conditions and didn’t list known food allergens on the product labels.

Robert Saper, director of integrative medicine and an assistant professor at Boston University School of Medicine, said dietary supplement manufacturers should have to demonstrate that their products are safe before they go on the market. One way to do that would be having an independent third party verify those products, he said.

Saper’s study last year in the Journal of the American Medical Association found that one in five herbal products used in Ayurvedic, or traditional Indian, medicines contained harmful levels of toxic metals.

Cohen said Congress must give the FDA more authority and resources to regulate the dietary supplement industry.

As of 2008, about 75,000 dietary supplements were available to consumers, an increase from about 4,000 in 1994, according to the GAO report.

Calcium, Folic Acid

Using supplements such as calcium and folic acid as well as other alternative medicines should be allowed as long as it’s safe, said Cohen of Harvard.

“If people want to take a garlic pill, I see no reason that they shouldn’t be able to take a garlic pill, but if they go and buy a garlic pill, they should make sure garlic is the only thing in there,” he said.

Shao, the supplement industry representative, said consumers should be cautious about products promising a “magic bullet” and should choose supplements made by brands they know and trust.

“These few companies, these outliers, they are undermining consumer confidence,” he said. “We support regulators going after them.”

More About Folic Acid

September 23rd, 2009

Deficiency of folate/folic acid is believed to be one of the most common nutritional deficiencies because only an estimated 11% of people consume the recommended 5-7 servings daily of vegetables and fruits. Here are four other causes of this deficiency.

Most members of the vitamin B-complex must be converted to a metabolically active form in the body. The active form of folates in foods and folic acid in supplements is called 5-methylenetetrahydrofolate or MTHF for short. This complex conversion requires good intestinal and liver function, adequate amounts of vitamins B2, B3, B6, C, plus zinc and serine. Produced in the liver, MTHF is secreted into the small intestine along with bile. From there it’s absorbed into the blood for transport into every cell of the body. Malabsorption, other digestive system problems, and liver disease may limit the ability of the liver to produce adequate amounts of MTHF (1).

Second, the conversion of folate/folic acid into MTHF requires an enzyme known as methylenetetrahydrofolate reductase (MTHFR). This MTHFR enzyme plays a crucial role in maintaining adequate levels of this metabolically active folate coenzyme required to convert homocysteine to methionine. If you’re interested in the pathway, see reference 2.
A common variation or polymorphism in the gene for MTHFR results in a less stable enzyme. Depending on the population, 50% of individuals may have inherited one gene for the less stable enzyme, and 5% to 25% of individuals may have inherited two copies, or are homozygous, for the abnormal MTHFR gene (3).

Third, certain prescription medications diminish the activity of MTHFR. The anticonvulsant, phenytoin, has been shown to inhibit the intestinal absorption of folate. Several studies have associated decreased folate status with long-term use of the anticonvulsants including phenytoin, phenobarbital, and primidone. Taking folic acid at the same time as the cholesterol-lowering agents, cholestyramine and colestipol, may decrease the absorption of folic acid. Methotrexate, a folic acid antagonist, is used to treat a number of diseases including rheumatoid arthritis and psoriasis. Some of the side effects of methotrexate are similar to those of severe folate deficiency, and increased dietary folate or supplemental folic acid may decrease side effects without reducing the efficacy of methotrexate (3).

Other medications have antifolate activity, including trimethoprim (an antibiotic), pyrimethamine (an antimalarial), triamterene (a blood pressure medication), and sulfasalazine (a treatment for ulcerative colitis). When nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin or ibuprofen, are taken in very large therapeutic dosages, they may interfere with folate metabolism. In contrast, routine low dose use of NSAIDs has not been found to adversely affect folate status (3).

In addition, alcohol interferes with folate absorption and folate metabolism, as well as increases folate breakdown. Kidney dialysis increases folate excretion.

A variety of health conditions are related to folate/folic acid deficiency: macrocytic or megaloblastic anemia which causes fatigue, weakness, and shortness of breath; elevated homocysteine; cardiovascular disease; inflammatory bowel disease; depression; cervical dysplasia; periodontal disease; cognitive disturbances; diarrhea; insomnia; non-senile dementia; and restless syndrome (4). You’ll find recommendations from the Mayo Clinic for supplementing folate/folic acid for 15 health conditions in reference 5.

Exploring the connections between folate and depression” Miller writes: “ . . . Folate deficiency is relatively common in depressed people, with approximately one-third of depressed individuals having an outright deficiency. Folate is . . . necessary for the proper biosynthesis of the monoamine neurotransmitters serotonin, epinephrine, and dopamine. The active metabolite of folate, 5-methyltetrahydrofolate (5-MTHF), participates in re-methylation of the amino acid metabolite homocysteine, creating methionine. S-adenosylmethionine (SAMe), the downstream metabolite of methionine, is involved in numerous biochemical methyl donation reactions, including reactions forming monoamine neurotransmitters. Without the participation of 5-MTHF in this process, SAMe and neurotransmitter levels decrease in the cerebrospinal fluid, contributing to the disease process of depression. . . . .There are few intervention studies of folic acid or 5-MTHF as a stand-alone treatment for depression related to folate deficiency; however, the studies that have been conducted are promising. Depressed individuals with low serum folate also tend to not respond well to selective serotonin reuptake inhibitor (SSRI) antidepressant drugs. Correcting the insufficiency by dosing folate along with the SSRI results in a significantly better antidepressant response (6).
