Neuropathy
Polyneuropathy, also known as peripheral neuropathy, is characterized
by weakness, tingling and pain in the hands and feet as well as
difficulty walking. Researchers who studied 500,000 residents of
Denmark, about 9 percent of that country's population, found that
people who took statins were more likely to develop polyneuropathy.10
Taking statins for one year raised the risk of nerve damage by about
15 percent--about one case for every 2,200 patients. For those who
took statins for two or more years, the additional risk rose to
26 percent.
According to the research of Dr. Golomb, nerve problems are a common
side effect from statin use; patients who use statins for two or
more years are at a four to 14-fold increased risk of developing
idiopathic polyneuropathy compared to controls.11 She
reports that in many cases, patients told her they had complained
to their doctors about neurological problems, only to be assured
that their symptoms could not be related to cholesterol-lowering
medications.
The damage is often irreversible. People who take large doses for
a long time may be left with permanent nerve damage, even after
they stop taking the drug.
The question is, does widespread statin-induced neuropathy make
our elderly drivers (and even not-so-elderly drivers) more accident
prone? In July 2003, an 86-year-old driver with an excellent driving
record plowed into a farmers' market in Santa Monica, California,
killing 10 people. Several days later, a most interesting letter
from a Lake Oswego, Oregon woman appeared in the Washington Post:12
"My husband, at age 68, backed into the garage and stepped
on the gas, wrecking a lot of stuff. He said his foot slipped
off the brake. He had health problems and is on medication, including
a cholesterol drug, which is now known to cause problems with
feeling in one's legs.
"In my little community, older drivers have missed a turn
and taken out the end of a music store, the double doors of the
post office and the front of a bakery. In Portland, a bank had
to do without its drive-up window for some time.
"It is easy to say that one's foot slipped, but the problem
could be lack of sensation. My husband's sister-in-law thought
her car was malfunctioning when it refused to go when a light
turned green, until she looked down and saw that her foot was
on the brake. I have another friend who mentioned having no feeling
in her lower extremities. She thought about having her car retrofitted
with hand controls but opted for the handicapped bus instead."
Heart Failure
We are currently in the midst of a congestive heart failure epidemic
in the United States--while the incidence of heart attack has declined
slightly, an increase in the number of heart failure cases has outpaced
these gains. Deaths attributed to heart failure more than doubled
from 1989 to 1997.13 (Statins were first given pre-market
approval in 1987.) Interference with production of Co-Q10 by statin
drugs is the most likely explanation. The heart is a muscle and
it cannot work when deprived of Co-Q10.
Cardiologist Peter Langsjoen studied 20 patients with completely
normal heart function. After six months on a low dose of 20 mg of
Lipitor a day, two-thirds of the patients had abnormalities in the
heart's filling phase, when the muscle fills with blood. According
to Langsjoen, this malfunction is due to Co-Q10 depletion.
Without Co-Q10, the cell's mitochondria are inhibited from producing
energy, leading to muscle pain and weakness. The heart is especially
susceptible because it uses so much energy.14
Co-Q10 depletion becomes more and more of a problem as the pharmaceutical
industry encourages doctors to lower cholesterol levels in their
patients by greater and greater amounts. Fifteen animal studies
in six different animal species have documented statin-induced Co-Q10
depletion leading to decreased ATP production, increased injury
from heart failure, skeletal muscle injury and increased mortality.
Of the nine controlled trials on statin-induced Co-Q10 depletion
in humans, eight showed significant Co-Q10 depletion leading to
decline in left ventricular function and biochemical imbalances.15
Yet virtually all patients with heart failure are put on statin
drugs, even if their cholesterol is already low. Of interest is
a recent study indicating that patients with chronic heart failure
benefit from having high levels of cholesterol rather than low.
Researchers in Hull, UK followed 114 heart failure patients for
at least 12 months.16 Survival was 78 percent at 12 months
and 56 percent at 36 months.
They found that for every point of decrease in serum cholesterol,
there was a 36 percent increase in the risk of death within three
years.
Dizziness
Dizziness is commonly associated with statin use, possibly due
to pressure-lowering effects. One woman reported dizziness one half
hour after taking Pravachol.17 When she stopped taking
it, the dizziness cleared up. Blood pressure lowering has been reported
with several statins in published studies. According to Dr. Golumb,
who notes that dizziness is a common adverse effect, the elderly
may be particularly sensitive to drops in blood pressure.18
Cognitive Impairment
The November 2003 issue of Smart Money19 describes the
case of Mike Hope, owner of a successful ophthalmologic supply company:
"There's an awkward silence when you ask Mike Hope his age.
He doesn't change the subject or stammer, or make a silly joke
about how he stopped counting at 21. He simply doesn't remember.
Ten seconds pass. Then 20. Finally an answer comes to him. 'I'm
56,' he says. Close, but not quite. 'I will be 56 this year.'
Later, if you happen to ask him about the book he's reading, you'll
hit another roadblock. He can't recall the title, the author or
the plot."
Statin use since 1998 has caused his speech and memory to fade.
He was forced to close his business and went on Social Security
10 years early. Things improved when he discontinued Lipitor in
2002, but he is far from complete recovery--he still cannot sustain
a conversation. What Lipitor did was turn Mike Hope into an old
man when he was in the prime of life.
Cases like Mike's have shown up in the medical literature as well.
An article in Pharmacotherapy, December 2003, for example, reports
two cases of cognitive impairment associated with Lipitor and Zocor.20
Both patients suffered progressive cognitive decline that reversed
completely within a month after discontinuation of the statins.
A study conducted at the University of Pittsburgh showed that patients
treated with statins for six months compared poorly with patients
on a placebo in solving complex mazes, psychomotor skills and memory
tests.21
Dr. Golomb has found that 15 percent of statin patients develop
some cognitive side effects.22 The most harrowing involve
global transient amnesia--complete memory loss for a brief or lengthy
period--described by former astronaut Duane Graveline in his book
Lipitor: Thief of Memory.23 Sufferers report baffling
incidents involving complete loss of memory--arriving at a store
and not remembering why they are there, unable to remember their
name or the names of their loved ones, unable to find their way
home in the car.
These episodes occur suddenly and disappear just as suddenly. Graveline
points out that we are all at risk when the general public is taking
statins--do you want to be in an airplane when your pilot develops
statin-induced amnesia?
While the pharmaceutical industry denies that statins can cause
amnesia, memory loss has shown up in several statin trials. In a
trial involving 2,502 subjects, amnesia occurred in seven receiving
Lipitor; amnesia also occurred in two of 742 subjects during comparative
trials with other statins. In addition, "abnormal thinking"
was reported in four of the 2,502 clinical trial subjects.24
The total recorded side effects was therefore 0.5 percent; a figure
that likely under-represents the true frequency since memory loss
was not specifically studied in these trials.
Cancer
In every study with rodents to date, statins have caused cancer.25
Why have we not seen such a dramatic correlation in human studies?
Because cancer takes a long time to develop and most of the statin
trials do not go on longer than two or three years. Still, in one
trial, the CARE trial, breast cancer rates of those taking a statin
went up 1500 percent.26 In the Heart Protection Study,
non-melanoma skin cancer occurred in 243 patients treated with simvastatin
compared with 202 cases in the control group.27
Manufacturers of statin drugs have recognized the fact that statins
depress the immune system, an effect that can lead to cancer and
infectious disease, recommending statin use for inflammatory arthritis
and as an immune suppressor for transplant patients.28
Pancreatic Rot
The medical literature contains several reports of pancreatitis
in patients taking statins. One paper describes the case of a 49-year-old
woman who was admitted to the hospital with diarrhea and septic
shock one month after beginning treatment with lovastatin.29
She died after prolonged hospitalization; the cause of death was
necrotizing pancreatitis. Her doctors noted that the patient had
no evidence of common risk factors for acute pancreatitis, such
as biliary tract disease or alcohol use. "Prescribers of statins
(particularly simvastatin and lovastatin) should take into account
the possibility of acute pancreatitis in patients who develop abdominal
pain within the first weeks of treatment with these drugs,"
they warned.
Depression
Numerous studies have linked low cholesterol with depression. One
of the most recent found that women with low cholesterol are twice
as likely to suffer from depression and anxiety. Researchers from
Duke University Medical Center carried out personality trait measurements
on 121 young women aged 18 to 27.30 They found that 39
percent of the women with low cholesterol levels scored high on
personality traits that signaled proneness to depression, compared
to 19 percent of women with normal or high levels of cholesterol.
In addition, one in three of the women with low cholesterol levels
scored high on anxiety indicators, compared to 21 percent with normal
levels. Yet the author of the study, Dr. Edward Suarez, cautioned
women with low cholesterol against eating "foods such as cream
cakes" to raise cholesterol, warning that these types of food
"can cause heart disease." In previous studies on men,
Dr. Suarez found that men who lower their cholesterol levels with
medication have increased rates of suicide and violent death, leading
the researchers to theorize "that low cholesterol levels were
causing mood disturbances."
How many elderly statin-takers eke through their golden years feeling
miserable and depressed, when they should be enjoying their grandchildren
and looking back with pride on their accomplishments? But that is
the new dogma--you may have a long life as long as it is experienced
as a vale of tears.
Any Benefits?
Most doctors are convinced--and seek to convince their patients--that
the benefits of statin drugs far outweigh the side effects. They
can cite a number of studies in which statin use has lowered the
number of coronary deaths compared to controls. But as Dr. Ravnskov
has pointed out in his book The
Cholesterol Myths,31 the results of the major studies
up to the year 2000--the 4S, WOSCOPS, CARE, AFCAPS and LIPID studies--generally
showed only small differences and these differences were often statistically
insignificant and independent of the amount of cholesterol lowering
achieved.
In two studies, EXCEL, and FACAPT/TexCAPS, more deaths occurred
in the treatment group compared to controls. Dr. Ravnskov's 1992
meta-analysis of 26 controlled cholesterol-lowering trials found
an equal number of cardiovascular deaths in the treatment and control
groups and a greater number of total deaths in the treatment groups.32
An analysis of all the big controlled trials reported before 2000
found that long-term use of statins for primary prevention of heart
disase produced a 1 percent greater risk of death over 10 years
compared to a placebo.33
Recently published studies do not provide any more justification
for the current campaign to put as many people as possible on statin
drugs.
