Though not described in the abstract, there was 50-100% more weight loss with the Portfolio diet than with the control groups in the study you cite. Visceral adipose tissue is highly active in elevating levels of inflammatory cytokines. All studies to date are reporting a consistent dose response curve of increasing CRP with increasing visceral/central adiposity.
You will be in my prayers, dear Juhana, whom I love, in Christ's name.
May you accept Him as your personal Lord and Savior, someday, so that you too will have eternal life and the awesome riches of His everlasting kingdom.
Here's how:

Please note that God truly made this special link describing that He is the great "I am" and that His message is as simple as the number 2 which is a number between 1 to 9 and reminds us of His 2 commandments, the 2 arms of the cross, the 2nd part of the Trinity, the 2 finger sign of the Prince of Peace [who remains *V*ictorious over death and satan], and the 2PD Approach. Let it not ever be written that Christ did not make His presence known here on Usenet :-)
Also, note that Exodus 16:16 continues to remind us that 16 oz plus 16 oz makes 2 pounds, which is "a certain measure of weight," which is what "omer" literally means in Hebrew.
Enter the 2PD-OMER Approach:

[quoted text clipped - 10 lines] :: the prevalence of the metabolic syndrome and its associated :: cardiovascular risk. I would like to know what was the percentage change achieved by the Mediterranean diet. I ask this because I would like to compare it to the cholesterol lowering effect of the Portfolio diet, which reduces CRP about 30 percent - almost as much as statins. However, the Portfolio diet is a vegetarian diet and its CRP lowering effect can not be counted on fish oils. (I am not denying the inflammation reducing effect of fish oils.)

But remember, inflammation is just one of the factors involved in insulin resistance. Triglycerides appear to physically interfere with the insulin / receptor interaction. And the HISS data show that there's some other unidentified factor that mediates insulin senstivity.

Effect of a mediterranean-style diet on endothelial dysfunction and markers of vascular inflammation in the metabolic syndrome: a randomized trial.
Esposito K, Marfella R, Ciotola M, Di Palo C, Giugliano F, Giugliano G, D'Armiento M, D'Andrea F, Giugliano D.
Chair and Division of Metabolic Diseases, Second University of Naples, Naples, Italy.
CONTEXT: The metabolic syndrome has been identified as a target for dietary therapies to reduce risk of cardiovascular disease; however, the role of diet in the etiology of the metabolic syndrome is poorly understood.
OBJECTIVE: To assess the effect of a Mediterranean-style diet on endothelial function and vascular inflammatory markers in patients with the metabolic syndrome.
DESIGN, SETTING, AND PATIENTS: Randomized, single-blind trial conducted from June 2001 to January 2004 at a university hospital in Italy among 180 patients (99 men and 81 women) with the metabolic syndrome, as defined by the Adult Treatment Panel III.
INTERVENTIONS: Patients in the intervention group (n = 90) were instructed to follow a Mediterranean-style diet and received detailed advice about how to increase daily consumption of whole grains, fruits, vegetables, nuts, and olive oil; patients in the control group (n = 90) followed a prudent diet (carbohydrates, 50%-60%; proteins, 15%-20%; total fat, <30%).
MAIN OUTCOME MEASURES: Nutrient intake; endothelial function score as a measure of blood pressure and platelet aggregation response to l-arginine; lipid and glucose parameters; insulin sensitivity; and circulating levels of high-sensitivity C-reactive protein (hs-CRP) and interleukins 6 (IL-6), 7 (IL-7), and 18 (IL-18).
RESULTS: After 2 years, patients following the Mediterranean-style diet consumed more foods rich in monounsaturated fat, polyunsaturated fat, and fiber and had a lower ratio of omega-6 to omega-3 fatty acids. Total fruit, vegetable, and nuts intake (274 g/d), whole grain intake (103 g/d), and olive oil consumption (8 g/d) were also significantly higher in the intervention group (P<.001). The level of physical activity increased in both groups by approximately 60%, without difference between groups (P =.22). Mean (SD) body weight decreased more in patients in the intervention group (-4.0 [1.1] kg) than in those in the control group (-1.2 [0.6] kg) (P<.001). Compared with patients consuming the control diet, patients consuming the intervention diet had significantly reduced serum concentrations of hs-CRP (P =.01), IL-6 (P =.04), IL-7 (P = 0.4), and IL-18 (P = 0.3), as well as decreased insulin resistance (P<.001). Endothelial function score improved in the intervention group (mean [SD] change, +1.9 [0.6]; P<.001) but remained stable in the control group (+0.2 [0.2]; P =.33). At 2 years of follow-up, 40 patients in the intervention group still had features of the metabolic syndrome, compared with 78 patients in the control group (P<.001).
CONCLUSION: A Mediterranean-style diet might be effective in reducing the prevalence of the metabolic syndrome and its associated cardiovascular risk.

>Sharon, > [quoted text clipped - 11 lines] > >William C Biggs, MD I'd like to add that there are some specific applications where getting enough of the substance to the right place is critical, even if the body makes enough for normal purposes and even if additional supplements are taken beyond that. Co-Enzyme Q10 is remarkably effective at reducing inflamation of the gums caused by gingivitas. But you won't see much effect at all if you merely swallow a 50 mg supplement every day. That gets spread out throughout the body and very little actually gets to the gums. But if you take that 50 mg capsule, puncture the end and use the liquid to brush your teeth you will see dramatic results far quicker than simply brushing with toothpaste.
I believe that current research has shown that inflamations almost anywhere in the body produce chemicals that are linked to triggering insulin resistance and thus type 2 diabetes. That appears to be why they are getting promising results with aspirin therapy. But while it is a good idea for anyone with gingivitas to correct that situation quickly, it is especially important for people with diabetes or pre-diabetes. But you have to get enough COQ10 to the right spot to do some good.

Sharon,
Almost all of the anecdotal reports on Co-Q have different doses. The original patent from Merck suggested they were going to try 35mg.
Co-Q has a long history of being the "non-vitamin". As you pointed out, most people can synthesize sufficient quantities of Co-Q, thus purists reject the using the term "Vitamin" with it. The theory is that it can't be a vitamin if you can make it yourself. Vitamins are only nutrients you can't make yourself.
Of course, the fact that Vitamin D is manufactured in the body as well is rarely mentioned by the purists....

FYI -for severe statin muscle damage, with mitochondrial damage, there are doctors and mitochondrial specialists who are using as much as 800 mg to 1200 mg per day, concurrent with halting the statin.

Charly,
Co-Q is readily available OTC. Even Sam's Warehouse Club carries it now.
If a patient on a statin complains of any myalgia or muscle weakness, I usually have them try 150mg a day.
Depending on the severity of the complaints, I might check a CK level to look for muscle inflammation. If the CK is high, I will stop the statin. Statins can cause myalgias or muscle weakness even with a normal CK level. In that scenario Co-Q is often very beneficial, and can relieve the muscle complaints.
I haven't heard of any adverse effects of Co-Q , other than some people have found their BG was lower while taking it.
BTW, one of my attendings from medical school , Michael Brown, and Merck patented the concept of adding Co-Q to a statin back in 1990.
Dr Brown shared the Nobel prize in Medicine with Joseph Goldstein for their discovery of the statin drugs. Look at patent 4,933,165 at www.uspto.gov .
IMHO, the incidence of myalgia while taking statins is WAY under-reported. That's why I wrote the letter published in the Wall Street Journal criticizing Pfizer for its plans to only market torcetrapib in combination with atorvastatin (Lipitor). Those persons with muscle problems on statins will not be able to get torcetrapib.
This scenario reminds me of the mid 80's when patients were telling their doctors that meds like Prozac reduced their libido, and the drug companies claimed it was no different than placebo.
The concept of a combination Co-Q / statin drug makes a lot of sense to me. It makes a lot more sense than "Caduet" which is combines Norvasc and Lipitor, or the 2002 winner of "Stupidest Drug Marketing Idea of the Year Award".... Pravagard , which was simply a package with Pravachol and an aspirin tablet. Not in the same pill mind you, it was two separate tablets.

Tiger Lily,
If you mean Arturo Rolla's cocktail, that was CAFE. Vitamin C, Aspirin, Folate, and Vitamin E.
IMHO, the Vitamin E should be dropped. The evidence for E was always very flimsy, and more recent studies suggest that it actually increases cardiac risk above 400 IU per day.
Aspirin is the best documented...Once you get started...don't stop!! Stopping the aspirin increases your risk of a heart attack or stroke by a factor of 3 over the next month.
I haven't seen Co-Q on any cocktail lists, but I do recommend it for selected people on statins.
I have never seen any published data about metformin affecting Co-Q levels. A quick PubMed search didn't pick up any hits, while there are plenty on statins and Co-Q.
Perhaps we can suggest another acronym to Arturo, such as Q-FAC.
Cheers,

Ken Baker Column
Are the risks of nutrient depletion by statins excessive?
Maintenance of healthy heart, nerve, brain, liver, and skeletal muscles requires CoQ10. Deficiencies have reportedly given rise to congestive heard failure, weakening of the heart muscles, attention problems, delayed reflexes, cognitive decline and memory impairment. There is no serious debate, CoQ10 is absolutely essential to the conversion inside each cell of nutrients and oxygen to energy. Don't leave home without it.
Last week we reviewed how Walter, a reader of this column, avoided the statin drug, Lipitor, by letting food be his medicine. That, coupled with vigorous exercise, kept him drug free and enabled him to avoid the risks of CoQ10 depletion.
The average healthy body has stored approximately 2,000 mg of CoQ10. Each adult uses about 500 mg a day. The average diet provides 5 mg daily. Where does the rest come from? We make it ourselves.
Our body synthesizes CoQ10. If there is not enough, supplements can bring up the slack. Internal synthesis of CoQ10 takes place in the liver, peaking at about age 21-- and by 30, the rate begins to decline. The process is similar to how the liver manufactures cholesterol. When a statin reduces cholesterol production, it also restricts production of CoQ10.
Most of the 67 million people that orthodox medicine estimates are in need of lifelong statin therapy are over age 50. Many were at risk for CoQ10 deficiency even before they started on the drug. The statins increase the prospect of harm. Last summer, the "Archives of Neurology" published a study from Columbia University College of Physicians & Surgeons reporting patients on Lipitor for 30 days had a 50 percent fall in CoQ10 blood plasma levels.
The drug company studies claim the risk is low, between .5 and 2.3 percent, depending on dose. That is somewhere between 335,000 and 1,540,000 people experiencing adverse events. Given that the drug companies only select healthy people for their drug studies, it is highly unlikely any of them were taking other drugs known to deplete CoQ10. The risk of serious adverse effects is almost certainly grossly understated.
When assessing the risks of statins, the cumulative effect of all drugs prescribed for the patient must be the focus of attention. It rarely is.
Heart disease is an especially serious problem for patients with Type II diabetes. Common drugs for diabetics that deplete CoQ10 include Dymelor, Micronase and Tolinase. Another commonly prescribed diabetic drug, Glucophage, depletes not only CoQ10, but also vitamin B12, a second risk factor for heart disease.
The cumulative effect of these diabetic drugs recently became a matter for more concern. Last summer, in the "Annals of Internal Medicine," a prestigious journal with approximately 115,000 subscribers, it was recommended that virtually all diabetics over 45 be prescribed a lifetime regimen of statin drugs. Should we be surprised if diabetics' rates of heart disease grow ever greater?
People who are depressed may also be prescribed statins. Several drugs commonly prescribed for depression deplete CoQ10: Adapin, Aventyl, Elavil, Tofranil, Pamelor, Sinequan and Norpramin. Another reader, suffering from neuropathy, was prescribed Elavil and two other pain killers that deplete B12. Her doctor mentioned neither CoQ10 nor B12. Yet these nutritional deficiencies are risk factors for the very disease he was treating.
Patients that are claimed to be at high risk because of elevated cholesterol may also be taking other drugs targeting cardiovascular disease. The following heart disease drugs may provide benefits, but they may also have adverse effects on heart health. When combined with statins, the total CoQ10 depletion could shift the balance from a net benefit to an unacceptable risk. Those drugs include: Corgard, Inderal, Lopressor, Betapac, Tenormin, Sectral, Biocardren, Aldomet, Catapres and Apresoline.
Orthodox medicine seems to have turned a blind eye to risks brought on by nutrient depletion. Drug companies do not test for or report on its consequences. The National Institutes of Health appears to be doing little. The FDA is oblivious. It has been petitioned twice to require a CoQ10 depletion warning for statins. So far, nothing.
Of the near-dozen statin takers who wrote in response to last week's column, only one reported being advised to supplement with CoQ10. More broadly, last summer's Clinical Practice Guidelines for diabetics from the American College of Physicians make no mention of CoQ10 supplements.
What to do? When prescribed a drug, always ask your doctor if it depletes any nutrients and, if so, what are the long term consequences. Certainly, if prescribed a statin, ask, "Is CoQ10 right for me?"
If you draw a blank with the doctor, try your pharmacist.
