Three days ago, I wrote an article about red yeast rice and it’s popular derivative drug Xue Zhi Kang. <http://qi-spot.com/2009/10/27/red-yeast-rice-for-cholesterol-fermented-fun/>.  Now, Medscape has put online a study about it.  Here it is with the usual highlights and commentary:

Red Yeast Rice and Hyperlipidemia: How Strong Is the Evidence?

3-Hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors, or statins, have proven to be effective in reducing lipid levels and improving the risk for cardiovascular disease. However, many patients may not tolerate statins over time, partly due to statin-associated myopathy. Does red yeast rice present a valid alternative treatment for patients with this adverse event? The randomized trial discussed in this review examined the efficacy, safety, and tolerability of red yeast rice among a cohort of patients with a history of statin-associated myopathy.

The significant benefits of statins are hard to refute. These are being reported even among patients at a low risk for cardiovascular disease. For example, in a 2009 study, within 12 months of the initiation of treatment, rosuvastatin was associated with significant regression of carotid intima-media thickness — a strong surrogate marker for cardiovascular events.[1] Moreover, statin treatment among low-risk patients is associated with a reduction in the risk for cardiovascular events. The Air Force/Texas Coronary Atherosclerosis Prevention Study (AFCAPS/TexCAPS) examined treatment with lovastatin vs placebo among patients without a history of cardiovascular events.[2] Researchers found that lovastatin reduced the risk for first coronary heart disease events by nearly half over an average follow-up time of 5.2 years. This included a 40% reduction in the risk for myocardial infarction. There was also no significant difference in the rate of severe adverse events when comparing the lovastatin and placebo groups.

In English:  Statins work.  Statins also harm muscles sometimes.  Can Red Yest Rice work for those who can’t take statins?

Sigh, gotta love it.  The question is not “can we use herbal medicine/diet instead of statins” but “can we use them when patient’s can’t tolerate statins”.

The next few paragraphs deal with explaining the very rare side effects of statins.  We’ll leave it to the curious reader to follow the link later on.  Now we focus on red yeast rice!

One strategy in the management of patients with statin-associated myopathy could involve the use of red yeast rice, the fermented product of the yeast species Monascus purpureus grown on rice. It has been used for medicinal and nonmedicinal purposes in China since 900 A.D., and it is promoted there as a means to improve circulation. Red yeast rice contains several compounds collectively known as monacolins, one of which is monacolin K, a powerful HMG-CoA reductase inhibitor and the same chemical as lovastatin. Because of this, red yeast rice has received increased attention in Western countries as a means to treat hyperlipidemia, and there is good research to support its efficacy. In one placebo-controlled trial of 83 individuals with hyperlipidemia, red yeast rice was associated with mean reductions in the concentrations of total and LDL cholesterol of 18% and 22%, respectively, over 12 weeks of treatment.[7] Red yeast rice also reduced serum triglyceride levels by 7% but did not significantly alter high-density lipoprotein (HDL) cholesterol levels. In another placebo-controlled trial, red yeast rice reduced total and LDL cholesterol levels by 27.7% and 21.5%, respectively, and red yeast rice decreased apolipoprotein B levels by 26%.[8]

In English, again – Red Yeast rice was proven to reduce bad cholesterol but not good cholesterol!

To help determine whether red yeast rice may be useful among patients with hyperlipidemia who do not tolerate a statin, the study under discussion in this review compared red yeast rice and placebo among patients with statin-associated myopathy. Patients from one cardiology practice in the United States were eligible for study participation if they were between 21 and 80 years old and had discontinued a statin because of myalgia. Participants’ LDL cholesterol levels were between 100 and 210 mg/dL at baseline, and patients with a serum triglyceride level of 400 mg/dL or more were excluded from study participation, as were those with a history of coronary heart disease.

Sixty-two patients underwent randomization to treatment with 3 red yeast rice 600-mg capsules twice daily, or matching placebo capsules with the same dosing schedule. The treatment period was 24 weeks. All study participants had previously been enrolled in a 12-week trial of lifestyle counseling to prevent cardiovascular disease. The mean age of the participants was 61 years, and 65% of the participants were women. The mean patient weight at baseline was 81 kg. The 2 groups were similar at baseline, except for a slightly higher mean pain score in the placebo cohort.

The main study outcome was LDL cholesterol level, as measured at baseline, week 12, and week 24. The mean values in the placebo group were 165 mg/dL, 154 mg/dL, and 149.8 mg/dL at baseline, week 12, and week 24. The respective levels of LDL cholesterol in the red yeast rice group were significantly better during the active trial period (163 mg/dL, 120 mg/dL, and 128 mg/dL, respectively). This represented a decrease in the baseline LDL cholesterol level of -27.3% at 12 weeks and -21.3% at 24 weeks in the red yeast rice group. Total cholesterol levels were also improved in the red yeast rice vs placebo groups, but there was no treatment difference in HDL cholesterol or triglyceride levels.

Researchers also examined other lipid values and patient weight, as well as specific surveys for bodily pain and laboratory assessments of creatine phosphokinase levels and liver-associated enzymes. There was no significant difference between the red yeast rice and placebo groups in the rate of adverse events and bodily pain, even when the researchers performed a subgroup analysis that was based on the number of statins that patients had previously tried. Four patients discontinued treatment in the red yeast rice group, compared with 1 patient in the placebo group. Creatine phosphokinase and liver-associated enzyme levels remained similar between the groups. Both treatment groups experienced a weight loss of approximately 3.5 kg from baseline.

Again in English: Red Yeast rice caused “bad cholesterol” to go down.  It did not cause any significant difference in both body pain (known statin side effect) and liver and kidney problems between the two groups.

And for their conclusion!

The collective research suggests that red yeast rice is effective and safe in improving the lipid profile among patients with hyperlipidemia. Some research even has suggested that red yeast rice, along with other nonprescription treatment, may be as or more effective than a statin. Becker and colleagues compared treatment with simvastatin 40 mg daily vs combination therapy consisting of enrollment in an intensive lifestyle intervention, fish oil supplementation, and red yeast rice supplementation.[9] The reduction in LDL cholesterol was approximately 40% in both treatment groups, and patients receiving the combination treatment experienced a greater reduction in body weight and serum triglycerides. Although these results are impressive, it is unclear which of the nonstatin interventions was most effective in improving study outcomes.

Red yeast rice does not have the impressive track record of statins in terms of the prevention of cardiovascular events. However, a trial of 5000 individuals with a history of previous myocardial infarction demonstrated that red yeast rice reduced the risk for nonfatal myocardial infarction by 62% and coronary disease mortality by 31% compared with placebo.[10] Red yeast rice also reduced overall mortality by one third compared with placebo.

More research is required with regard to the clinical outcomes of red yeast rice before this treatment can be recommended as an alternative to statins to treatment-naive patients with hyperlipidemia. Concerns about red yeast rice toxicity have been based on monacolin K, the natural lovastatin. Myopathy and rhabdomyolysis,[11,12] similar to that seen with lovastatin, have been reported in case reports. Hepatotoxicity is the main concern, with reports on red yeast rice’s effects on the liver being variable. Some studies have shown theoretical potential for hepatic damage,[13,14] and others have reported no harm in humans.[15] In some animal studies (rats and mice), high doses were tolerated without liver toxicity.[16-18] Because of this finding, statins themselves and any agents that interact with statins should be avoided by those taking red yeast rice.

There are also common questions associated with any complementary and alternative therapy about standardization of the preparation and reimbursement for long-term treatment. However, among special cohorts of patients, particularly those with statin-associated myopathy, red yeast rice appears to be a viable alternative treatment. Physicians should weigh the potential risks and benefits of statins vs alternative treatments for individual patients on the basis of their history of treatment and cardiovascular risk.

Okay, I meant that as a joke.  What isn’t a joke is that so many people have sleep problems and are reliant on western drugs that sometimes counting sheep is the only apparent alternative option.  Just today, after our weekly conference at the University of the Philippines College of Medicine Dept. of Family and Community Medicine, a colleague asked me to treat her with acupuncture for her jet lag.

How fitting, it seems, that I then stumble on this news article a few hours later:

Traditional Chinese Medicine Effectively Treats Insomnia <http://www.naturalnews.com/027348_medicine_insomnia_Chinese.html>

Melissa Sokulski starts:

Acupuncture, which actually treats the person, not the disease, helps to balance the body’s energy, strengthening weak areas and moving energy where it’s stuck…

Insomnia can have many causes; figuring out the cause is an important part of diagnosis and treatment. For instance, pain can cause insomnia because the person is not able to get into a comfortable position for sleeping and the pain wakes them up. In that case acupuncturists treat the pain.

Okay, “balancing body energy” isn’t exactly accurate, but it’s not that far off either.  What she did hit right on the point (pun intended) was the importance of treating the CAUSE and not just the symptom.  Of course, for western medicine, cause means “what biological agent is missing or excessive” whereas for us cause means “what’s causing the imbalance” whether internal or external…

Is Counting Sheep the Gold Standard for Insomnia?

The rest of the article is so good I’ll just reprint it here, but it ends with some points and formulas that can be used and I discourage people from taking these over the counter – it is still best to be evaluated by a professional:

Eating late at night is a common cause of insomnia. When people stop eating after 7 pm, sleep often comes much more easily and is more peaceful. According to the Chinese Clock, digestion is the strongest in the morning, between 7 am and 9 am for the Stomach, and 9 am to 11 am for the Spleen/Pancreas. Twelve hours later (7 pm to 11 pm) digestion is the weakest, and eating at this time will cause gas, bloating and indigestion, making it difficult for one to fall asleep easily. Other causes of insomnia according to Traditional Chinese Medicine are yin deficiency, an imbalance of yin and yang, heart imbalance, spleen deficiency and stagnant liver qi.

In my practice, Spleen Deficiency is the most common cause of insomnia.  It leads to decreased production of Blood and thus, the Mind has no place to rest.  Thus, sleep is inefficient.  EVERYONE these days seemingly has some form of liver qi stagnation.  I believe it affects sleep by affecting Blood as well.  (In TCM, the Liver stores Blood.)

Acupuncturists take a detailed history, which includes questioning, pulse analysis and tongue diagnosis, to give a complete picture of the patient as a whole. Even if it is determined that two different patients have insomnia as a result of yin deficiency, their treatments may still be different, depending on each person’s constitution (strength and type of overall body and health) and other factors.

This is what makes acupuncture so individualized and effective: there is no one prescription for a condition. Each time a patient comes in, they are re-evaluated, and each treatment is specifically selected. This is also why it is so common to see all sorts of symptoms clear up – not just the one someone has come in to treat. Rarely do acupuncturists just work on one symptom alone; in every treatment, the whole person is being addressed and treated.

Again, an emphasis is put on customized treatment for an individual person.  Sure, by picking points and formulas symptomatically, you can treat symptoms.  But that is not the same as effecting a long term solution.  It does sound weird, though when I question an insomniac lady about her menses and poo-poo in great detail…
