The Real Problem
What is the
proper dose?
What should you
do?
Summary
The decision in August 2001 by the German Pharmaceutical
giant Bayer AG to withdraw the cholesterol-lowering statin drug Baycol from
the market shocked the world. For years, the public was led to believe that
statin drugs lowered cholesterol and possessed other health benefits as
well. Millions of statin prescriptions are written yearly in the United
States alone.
Unfortunately, Baycol was linked to
31 deaths. Moreover, deaths occurred
at the manufacturer's recommended initial dose (0.4 mg/day) as well as at
the highest dose (0.8 mg/day). The majority of deaths occurred in elderly
patients and more often in women.
There are other statin drugs on the market, such as Lipitor (the best seller). Like Baycol, these drugs are linked to the same rare muscle weakness, known as myositis, which occurs in about 1 in 1,000 statin users. Myositis occasionally progresses to rhabdomyolysis -- a complete breakdown of muscle cells that can lead to kidney failure and death. Some experts believe that pravastatin (Pravachol) and fluvastatin (Lescol) may have less potential for this deadly drug interactions. The data at this time are not sufficient to declare one statin drug safer or more dangerous than the others.
Drug interactions and side effects with statin drugs are not new. Numerous scientific literatures have reported adverse interaction including myositis when combinations of statins and other drugs, including warfarin (used to prevent blood clotting), clarithromycin (an antibiotic), and ketoconazole (an antifungal drug), are used. Laboratory tests have shown cancer development and liver damage, in animals, when high doses statin drugs are administered.
The Baycol fiasco is just the tip of the iceberg, illustrating the
growing potential for medical complications from drug interactions. Worldwide,
doctors are increasingly relying on numerous pharmaceuticals to control
chronic conditions , from elevated cholesterol to diabetes to high blood
pressure and osteoarthritis. In about a third of the Baycol cases, deaths
occurred among people who also took gemfibrozil (Lopid) - a drug used to
lower triglyceride levels.
Most statin adverse effects, including the
musculoskeletal (including rhabdomyolysis) and liver damage, are dose-related.
That is, higher doses bring increased risks. Each
doubling of the statin dosage also doubles the incidence of liver enzyme
elevations that exceed three times the upper limit of normalcy. The
Food and Drug Administration earlier reported 90 cases (63 confirmed)
of liver failure and more than 30 deaths linked to statin drugs. For years,
numerous researchers have been ringing the warning bell but were overruled.
The public has been led to believe that side effects of statin drugs,
if any, are minimal. Professionals are told that the benefits
outweigh the risk.
What is the proper dose?
Obviously, each person's dosage of any statin
drug should be as low as possible to achieve the target LDL cholesterol.
This is particularly
important for the elderly, women, and those of lesser weight. While
seniors comprise only 17% of the U.S. population, they sustain 51% of the
deaths from medication reactions. Studies have shown that up to 17% of all
hospitalizations of the seniors are related to medication reactions. Often
overlooked are women and certain minority groups such as Asians who are
smaller in size. Treating these with regular dosage could be a prescription
for disaster.
According to the package insert of Baycol, the recommended initial dose
is 0.4 mg/day. This dosage reduces LDL by 34% on average. But 0.3 mg --
25% less medication -- reduces LDL by 31%. This target is sufficient
for millions with elevated cholesterol to reach. No provision is made for
those of different body weight, age, or gender.
Some doctors start patients at even higher doses than manufacturers recommend
due to poor information. Product inserts of most statin drugs (including
Baycol) do not include guidelines on how to titrate dosage based on the
patient's weight and age. The lowest available dose of Lipitor, the best-selling
statin in America, may be stronger than millions of patients require
to achieve their target LDL cholesterol level
Patients are treated like statistical averages,
not like individuals -- even when many individuals probably get better than
average responses and therefore need only low doses.
The end result is over-treatment, which produces
predictable and avoidable problems. Overuse of statin therapy
was found among 69% of patients undergoing primary prevention and among
47% of patients undergoing secondary prevention in a recent article from
JAMA. Simply put - over-treatment means increased, unnecessary risks
for the patient. For some, especially those in compromised conditions,
this may put them over the edge.
The rational physician has a duty to administer
the lowest rational dosing not only to achieve the target total cholesterol
and LDL cholesterol levels, but also to avoid adverse effect.
What should you do?
If you are taking Baycol, talk to your doctor about switching to other drugs.
Until more details are known, here is what you need to know if you take
any statin drugs:
1. Watch carefully for muscle tenderness or weakness. Look for
feelings of weakness that can be localized or diffuse. It can occur independent
of exercise. Fever can be another symptom of muscle weakness. Be alert.
2. Seek immediate medical attention if your urine turns brown --
a symptom of muscle proteins' being excreted through the kidneys.
3. Ask about a regular liver function test.
Such tests are routinely performed before statins are started
and again 10 to 12 weeks later to ensure proper liver health. A more accurate
test -- either creatine kinase (CK) or creatine phosphokinase (CPK) -- should
be considered if muscle cells break down are suspected.
4. Inform your doctor what other medications
you take. Deaths have been reported not only in people who also
took Baycol with gemfibrozil (Lopid), but also in those who took other statins
with other drugs, including cyclosporin. Those with concurrent
heart disease must know that statin drugs lowers the coenzyme Q10 level
in the body. Those who are on Coumadin or other blood thinners for
conditions such as atrial fibrillation must also pay extra attention for
possible drug interactions.
6. Discuss with your doctor the proper dosage, remember
that the best dosage is the lowest effective dosage.
The trend to reduce serum total and LDL cholesterol started in the past two decades; when studies linked high saturated fat intake to increased serum cholesterol level. Cholesterol lowering statin drugs do reduce LDL cholesterol and a high LDL cholesterol level has been linked to increased cardiovascular disease. During this period, the average daily dietary fat consumption has gradually decreased, but the incidence of cardiovascular disease continues to increase. Obviously, the low fat high carbohydrate diet, so advocated as ideal for atherosclerosis prevention, does not work.
Sugar consumption has been increasing for the past 100 years and the trend remains unabated. An increased rate of cardiovascular disease is directly correlated to sugar intake and not fat intake. Most people don't realize that the surest way to reduce cholesterol is by reducing sugar intake and not reducing dietary cholesterol. Sugar includes grains such as wheat and rice. Also included are starchy underground vegetables such as potato, yam and carrot which convert quickly into sugar once inside the body. Sugar increases triglyceride storage and cellular oxidative damage. The body has been assaulted, especially the vascular wall, in a high sugar environment. It tries to self-repair and compensates by producing cholesterol and lipoprotein(a) from the liver. Cholesterol from the liver is transported to the rest of the body in the form of LDL cholesterol, a sticky substance that acts to patch up micro fissures at the inner layer of damaged blood vessels. Unfortunately, cholesterol and its relative lipoprotein(a) (so produced by the liver) accumulate and over time forms an atherosclerotic plaque. In reality, oxidative stress from a high sugar environment is the biggest trigger factor for increased cholesterol production in the body. Simple logic dictates that control of oxidative stress and sugar imbalances will automatically normalize the blood cholesterol level. And indeed it does.
In fact, studies have shown
that a diet high in cholesterol will not lead to high blood cholesterol
if the subject is healthy. The blood cholesterol level only increases by
3 mg/dl after ingestion of one egg day for a continuous period of 6 weeks
(one egg contains about 230 mg of cholesterol) in repeated studies. Clearly,
dietary cholesterol is not the main culprit.
On the contrary, too low a plasma cholesterol is not healthy.
Blood cholesterol levels below 150 mg/dl have been linked to a higher incidence
of cancer. It is equally important to pay attention to the total cholesterol
/ HDL cholesterol ratio and not to rely on the absolute level of total cholesterol
itself as an indicator of cardiovascular heath. Some other important indicators
include lipoprotein(a), homocysteine, and LDL cholesterol level.
Looking at the broader picture, one can easily surmise that the culprit of many degenerative diseases, including high cholesterol, premature aging, and arthrosclerosis, rest with the imbalance of two simple elements - oxygen and sugar.
Oxidative stress, from excessive free radical damage in the oxygen respiratory chain, damages vascular walls. This leads to the excessive production of LDL cholesterol by the liver as the body tries to repair the "damaged vessels" which are undetectable by current laboratory measurements. Such LDL cholesterol and its relative lipoprotein(a), as earlier mentioned, form atherosclerotic plaques. Animals who have endogenous production of vitamin C that act as anti-oxidants, for example, rarely get heart attacks. Polar bears, for example , have a constantly elevated blood cholesterol level of 400 mg/dl and they seldom suffer from heart attacks. Their vascular system is protected by anti-oxidants. Humans, on the other hand, cannot produce vitamin C and must depend on exogenous supply for such anti-oxidant.
Sugar is the second insult. While we cannot live without sugar, excessive sugar intake leads to increased oxidative stress, triglyceride formation and cortisol level. These are all pro-aging factors.
High sugar intake is linked to an increased risk of heart
disease. Simple sugars are the primary source of high triglycerides, a type
of blood fat, and very low-density lipoproteins (LDL), which are an independent
risk factor for atherosclerosis. Sugar lowers good HDL cholesterol and raises bad LDL cholesterol
and blood pressure levels. It is estimated that a high sugar
intake may account for as many as 150,000 premature deaths from heart disease
in the US each year.
Studies have been conducted to support this. In one research trial, 18 male
subjects received normal food followed by a rigorously specified diet in
which protein and carbohydrate requirements were met by amino acids, essential
fat, and glucose. The average concentration of cholesterol in the initial
period, on normal food, was 227 mg/dl. After two weeks on the restricted
glucose diet, it had dropped to 173. Two weeks later, the level was at 160.
When the diet was altered by replacing 25 percent of the glucose with sucrose
(while all other dietary constituents kept constant), the average cholesterol
level rose from 160 to 178 within one week and to 208 within two weeks.
The researchers carried the study one step further. The sucrose was replaced
with glucose again. With this change, the cholesterol concentration dropped
back to 175 within one week and the decline continued. It finally leveled
off at 150 mg/dl, which was 77 mg/dl less than the initial value. This research
finding links the consumption of sucrose (table sugar) directly to increased
cholesterol. The exact mechanism is still under research.
In addition to sucrose, fructose also raises the blood triglyceride level.
In a clinical trial conducted at the University of Minnesota, researchers
followed 24 healthy adults who received one of 2 diets assigned randomly
for a period of 6 weeks and then switched back to the other diet for 6 weeks.
One diet provided 17% of energy as fructose and the other diet was sweetened
with glucose and absent of fructose. Both diets contained common foods and
contained nearly identical amounts of macronutrients. The researchers found
that, in men, the fructose diet raised plasma triglyceride levels by 32%,
although there was no effect seen with the women being studied.
Elevated triglyceride blood level of in itself
is a strong and independent risk factor for heart attack among middle-aged
and elderly men. In fact, studies have shown that blood triglyceride
level was a stronger risk factor than total cholesterol alone. It is not
known why women appear to be immune to this other than postulations that
the high level of estrogen acts as a protective factor. The exact mechanism
is still under investigation.
Elevated cholesterol is a symptom and not a disease. The real disease is oxidative damage from excessive free radical damage caused by excessive metabolism of oxygen and sugar. Humans lack the endogenous capacity to produce vitamin C, a natural anti-oxidant. Instead, the body produces cholesterol as a surrogate. If you understand this concept, it is easy to appreciate that high cholesterol and a host of other age-related diseases, such as arthrosclerosis, are nothing more than a series of symptoms reflective of the body's response to imbalanced oxygen and sugar metabolism. This may be a simplistic concept, but it drives home an important concept. To normalize cholesterol levels permanently, proper control of your oxygen load (through reduction of oxidative stress by taking anti-oxidants) and sugar load (by avoiding foods that are high in sugar and concentrate on low glycemic index food) is the first and most important step.
There is no doubt that statin drugs bring down LDL cholesterol level. The problem is that there is dark side to these drugs. Statin drugs have been shown, for example, to increase fasting serum insulin levels by 13%, and decrease serum concentration of important antioxidant vitamins by up to 22%. There is also the significant lowering of serum Co-enzymeQ10, beta-carotene, and alpha-tocopherol level.
Unless you genetically have high cholesterol, lowering plasma
LDL cholesterol can be achieved effectively by eliminating trigger elements
through diet and lifestyle modifications. This can be done successfully by following my Anti-aging
Food Choice Program and adopting my Anti-aging
Strategies. They
will lower your cholesterol naturally without side effects. Taking
drugs to control cholesterol should be a method of last resort.
Since triglyceride elevation is almost universally related to dietary intake
of sugar (including grains). It is one of the most easy and straightforward
problems to correct with proper diet alone. The decline is dramatic and in the
matter of weeks if the proper low glycemic low grain anti-aging diet is followed.
Start with eliminating all grain products from your evening meal. This includes
wheat, rye,barly, potato, bread, and rice. You may find it difficult in the
beginning and experience craving. This is quite common because your body is
already addicted after years of taking in grains and , then cut back by 30%.
Do this for at least 60 days. As your body slowly get used to reduced grains
intake , then also reduce grains intake at lunch. Substitute with more above
the grounds vegetables, eggs ( raw is best, and try not to cook the yoke too
well ) , unroasted nuts. Oils are acceptable as longa as not exposed to high
heat. Use virgin olive oil for salads and light stir fry, butter for high heat
frying, and coconut oil for deep frying ( which should be kept to a minimum).
As usual, no dessert after dinner , and reduce snack before bedtime. All refined
carbolydrates such as cookie , ice cream ,and chips should be avoided. Follow
the above, and you will be surprised how quickly the triglyceride comes down.
As the triglyceride normalize, the total cholesterol will reduce automatically,
and the total cholesterol to HDL cholesterol ratio will automatically improve.
