Study: Extra folic acid may protect brain

     Study: Extra folic acid may protect brain

     WASHINGTON (AP) -- High-dose folic acid pills -- providing as much of
the nutrient as 2.5 pounds of strawberries -- might help slow the cognitive
decline of aging.

     So says a Dutch study that's the first to show a vitamin could really
improve memory.

     The research, unveiled Monday at a meeting of Alzheimer's researchers,
adds to mounting evidence that a diet higher in folate is important for a
variety of health effects. It's already proven to reduce birth defects, and
research suggests it helps ward off heart disease and strokes, too.

     The new study doesn't show folic acid could prevent Alzheimer's _ the
people who tested the vitamin didn't have symptoms of that disease.

     But as people age, some decline in memory and other brain functions is
inevitable. Taking 800 micrograms of folic acid a day slowed that brain drain,
reported lead researcher Jane Durga of Wageningen University in the
Netherlands.

     In the study, 818 cognitively healthy people ages 50 to 75 swallowed
either folic acid or a dummy pill for three years.

     On memory tests, the supplement users had scores comparable to people
5.5 years younger, Durga said. On tests of cognitive speed, the folic acid
helped users perform as well as people 1.9 years younger.

     That's significant brain protection, with a supplement that's already
well-known to be safe, said Johns Hopkins University neuroscientist Marilyn
Albert, who chairs the Alzheimer's Association's science advisory council.

     "I think I would take folic acid, assuming my doctor said it was OK,"
Albert said. "We know Alzheimer's disease, the pathology, begins many, many
years before the symptoms. We ought to be thinking about the health of our
brain the same way we think about the health of our heart."

     Indeed, there's enough research now suggesting that there are ways to
gird the brain against age-related memory loss and Alzheimer's that the
association has begun offering classes to teach people the techniques.

     Topping the list:

       a.. Exercise your brain. Using it in unusual ways increases blood flow
and helps the brain wire new connections. That's important to build up what's
called cognitive reserve, an ability to adapt to or withstand the damage of
Alzheimer's a little longer. In youth, that means good education. Later in
life, do puzzles, learn to play chess, take classes.

       b.. Stay socially stimulated. Declining social interaction with age
predicts declining cognitive function.

       c.. Exercise your body. Bad memory is linked to heart disease and
diabetes because clogged arteries slow blood flow in the brain.
       Experts recommend going for the triple-whammy of something mentally,
physically and socially stimulating all at once: Coach your child's ball team.
Take a dance class. Strategize a round of golf.

       Diet's also important. While Alzheimer's researchers have long
recommended a heart-healthy diet as good for the brain, Monday's folic acid
study is the first to test the advice directly.

       Previous studies have shown that people with low folate levels in
their blood are more at risk for both heart disease and diminished cognitive
function.

       Durga said it's not clear how folic acid might work to protect the
brain. Some studies suggest folate lowers inflammation; others suggest it may
play a role in expression of dementia-related genes.

       Folate is found in such foods as oranges and strawberries, dark-green
leafy vegetables and beans. In the United States, it also is added to cereal
and flour products. The recommended daily dose here is 400 micrograms; doctors
advise women of childbearing age to take a supplement to ensure they get that
much.

I wonder if the study addresed short term memory loss, the
phenomenum those of us who experience it call "senior moments"?

I don't believe my reasoning powers have begun to fail, nor my
ability to read and absorb fairly challenging material.

But I do momentarily forget names of people and books and other
facts I know well.  In a converation I find myself stumbling to
recall a name -- sometimes I have to menally recite the alphabet
to see if coming across the letter with which the name begins will
"job" my memory.    I am age 75 and this has been going on for
a few years now.  Usually, even if I do nothing to stimulate
memory, the name pops up in my mind a bit later.  This happens
to me far more often when talking to someone than when writing.
Although I do make use of Google to give me clues sometimes as to
the name or term I want to recall:)

My daughter once worked in a nursing home and tells me, when I once
got dressed to go off to church on a Saturday, that she will put up
a big board that says "Today is Tuesday.  The President is George
Bush. You live in New York City."

People who experienced statin induced memory loss describe such
incidents, and say they put up with it for a long time thinking, and
being told, it was due to aging, or Alzheimer's, or 'going crazy'. It
was only when they stopped the drug and began to recover that they and
their families realized incidents such as you describe are not normal.

It is this, not some boogeyman mental illness, that we mean when we
speak of statin induced cognitive adverse effects.

Statin induced cognitive adverse effects including memory loss,
confusion, disorientation, forgetting how to do things one has always
done, such as drive a car, aphasia and more are described here:

"Statin drugs don't do that" was a refrain the author heard hundreds of
times from physicians and pharmacists as, four years ago, he began to
investigate his own mysterious reaction to Lipitor. As a former
astronaut, aerospace medical research scientist, flight surgeon and
family doctor, he was appalled by the lack of information in his own
medical community on the true side effects of the statin drugs."

In my own case, and in the experiences of many seniors I've
discussed this with, the transient memory loss we call
"senior moments" had nothing at all to do with taking statins
since none of us were.  I've noticed it for a few years now
and only began taking a statin last fall.

My interest was in knowing if folic acid could help those
who experience these "senior moments".

Statin induced memory loss is very like normal memory loss; that is
exactly why it is often overlooked by the person experiencing it,
health care practitioners and others. There isn't some new variety of
memory loss which only happens with statins.

I don't think it's wise to supplement with folate without talking it
over with one's physician. Folate supplementation may not be innocent;
it can mask a B12 deficiency, and there is no one-size fits all for how
much or what to take to circumvent that.

Below, a discussion with David Rind on the issue of Folate
supplementation:

"Zee wrote:

> only a disease of women.

Hard to know from this study, but the results are at least mildly
concerning. Others have worried that folate can promote cell turnover
and so could increase the risk of tumors. I would guess we'll see a
series of other articles looking at long term outcomes after trials of
folate to see if there's evidence of increased cancer risk. These
current data are very preliminary.

~~~~~~~~~~~~~

In the absence of definitive evidence (like a large randomized trial of
folate supplementation for primary prevention of heart disease) we're
all left with making our best guesses about what does or does not make
sense to do. Personally, if my only risk factor for coronary heart
disease were an elevated homocysteine level, I would not take high dose
folate supplementation.

And, in general, if I thought my risk for coronary heart disease were
too high because of some series of risk factors, I would take a statin
whatever those risk factors actually were. That's because my
interpretation of the various evidence is that just about everyone can
expect around a 25 percent reduction in their risk of coronary disease
by taking a statin. This relative reduction translates into a pretty
small absolute decrease in people at low risk and a pretty large
absolute decrease in people at high risk, but it's there for just about
every group of people that has been studied. (People on dialysis are
probably an exception to this.)

I suppose it could turn out that statins increase the risk of cancer,
but there's certainly no strong evidence in that direction currently.
In
fact, there's some weak evidence to suggest that they decrease the risk
of various cancers. In any case, in the large trials of statins overall
mortality has been pretty consistently reduced. So if statins have bad
side effects, they do not seem to be large enough to overwhelm the
favorable effects of statins on mortality, at least in people at
increased risk for coronary heart disease.

Maybe. But even if the analysis in the above study is correct, it's
possible that you could be decreasing the risk of strokes but
increasing
the risks of cancer. This is not to say that I think a daily supplement
with 400 mcg of folate is a bad idea -- just that we really don't have
strong evidence on the issue the original poster raised as to whether
folate supplementation could have harmful effects.

I realize this sort of thing has been reported to affect people
on statins, however, the "senior moment" thing is common among
those in my age group who never have taken a statin and quite
precedes statin use in my own case.

We in a senior newsgroup frequently discuss
it.

My question was, is this the kind of memory loss that folic acid
can aid in overcoming to some extent.

You HAVE to be taking a statin! Are you sure? Maybe you really do take a
statin, but the statin has made you forget that you take it... :-) You
mean you really could be "normal"? You mean there just might be another
reason for memory loss NOT related to statins? [tongue out of cheek].

I would think that "cognitive decline of aging" contributes to those
senior moments. Although folic *has* been shown to lower homocysteine
levels, I think there needs to be more study on it's anti-cognitive
decline effect. With that said, I don't think there would be any harm in
adding it to your daily supplements along with some b6 & b12.

Again, my response is; taking folate may not be innocent and I wouldn't
do it without discussion with a physician.

There are pros and cons to the folate supplementation argument.
Possible increase in some cancers is a con. Help in recovery from
statin induced peripheral neuropathy and myopathy may be a pro.

Because you have said you have had muscle pains and aches since statin
use, you should be tested for peripheral neuropathy and/or
mitochondrial myopathy.

Vitamin B supplementation is used to treat peripheral neuropathy and
may also be helpful for statin induced myopathy.

They talk about cognitive speed, so maybe. I think long term memory would be
harder to test. I'll keep a look out for more on this.

For me, I think time of day may be a factor. :)

I do exactly the same thing and I am 62. Except often is is a movie star and I
look her (almost always a her!) up on the Internet Movie Data Base (IMDB) by
looking up a movies she was in or remembering someone else in a movie she was
in.

I do forget the day sometimes. But have various things that keep me in control
on that.

Yes, it is helpful to have the date on my computer:)

Other than forgetting names and other scraps of data temporarily,
my biggest memory problem is forgetting what it was I was going to
do next.  A few minutes ago I walked into the kitchen to get something
out of the freezer, and now I'm back at my computer and didn't do it.
I could not remember why I had gone into the kitchen.  It just came to
me -- whole wheat bread for breadcrumbs to coat some fish.  Let's
hope I can make it through this time around:)

You are not alone. I cut up 3X5 cards with things to do. Leaving notes
about  something I had to do after 7 hours for CABG four years ago.
Before that I also went thru the alphabet for memory clues as it works.
Long term is wonderful and I have not got lost yet ;))

Personal opine is that any drug can have an impact as well as traumatic
experiences on our minds.   One reason why I avoid horror movies and
Stephen King Books. ;))  Photographic memory  yes but short term like I
once wrote is so important and now amiss.   If I added sugar to my
coffee in the am  trivial but  other questions arise like did I turn off
the grill ?

Double check for safety is the rigor.

Yes, I check for safety before leaving the house.  To make sure
the oven is not on, for one.  Luckily we have an iron that shuts
itself off within a short period of time.  Before I made it an
iron clad rule to check everything, I would find myself halfway
down the block and need to return.  Once I found water boiling on
the stove and that did it.

Yes, I do that kind of thing too. Most typical is doing something - like
writing here - and saying I'm going to have to look up something on Google.
Than a total blank 5 mins. later. Very often it comes back within a couple of
hours or so, however.

While small memory glitches can happen at any age, pervasive memory
loss is not normal in one's 40s and 50s or even 60s and 70s.

Efforts to minimize the seriousness of statin induced cognitive adverse
effect is typical of what those taking statins and injured by them did,
until it was too late.

Do not attribute memory problems to aging or allow your physicians to
do that. This is not only ageist but dangerous.

Memory loss is a symptom not a joke. And brain damage from statins may
be irreversible.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Doug Peterson has not recovered from his statin induce brain injury. He
is  much worse than depicted here, January 2004, and has been diagnosed
with damage to his cerebellum.

LIFE AFTER LIPITOR: Is Pfizer product a quick fix or dangerous drug?

Residents experience adverse reactions

By Melissa Siig, Tahoe World Staff

At first glance, Tahoe City resident Doug Peterson looks like he is
recovering from a stroke.

His speech is slurred, he has difficulty walking in a straight line,
and he can't sign his own name. By afternoon, he is so fatigued he has
to sit down for the rest of the day. When asked his age, Peterson says
he is 52. His wife Karla, standing nearby, corrects him. He is 53.

Doug has never had a heart attack, and until the onset of the symptoms
almost three years ago, was an active skier, biker and scuba diver. Now
he is limited to walks on the treadmill. Doug traces his problems to a
drug he started taking almost three years before his health began
deteriorating - Lipitor. Two other Tahoe City locals have also
experienced negative side effects from taking Lipitor or other statins,
the name for a family of cholesterol-fighting pills.

While there is no concrete evidence linking Doug's health problems to
Lipitor, after doing years of research, meeting with doctors and
talking to other statin sufferers all over the world online, he and
Karla are convinced of the connection. Pfizer, the maker of Lipitor,
claims the drug is effective in lowering cholesterol and has minor
side-effects. But as Doug and others would ask, is it worth it?

WONDER DRUG OR DANGEROUS PILL?

Doug, who has hereditary high cholesterol, was first prescribed
Mevacor, a statin made by Merck, in 1998. Six months later, his doctor
had him switch to Lipitor, which comes in higher doses, and upped his
dosage from 10 to 20 mg. His cholesterol dropped from 285 to a low of
160.

"The doctor was very pleased," said Doug, "but meanwhile the symptoms
started."

In the fall of 2000, Doug began having restless sleep patterns. His
twitching and flying arms got so bad that Karla had to sleep in another
room. One time, Doug even fell out of bed. The couple didn't think
anything was seriously wrong until a few months later when Doug started
slurring his words. This was followed by a loss of balance and the
beginning of what Doug calls the "statin shuffle" - a slow, wobbly walk
across a room. Next to slide was Doug's fine motor skills. It took him
five minutes to write four words, much of which was illegible. Finally,
he tired easily and his cognitive memory processing diminished. He had
trouble following books with complex plots.

Confounded by Doug's illness, over the next two years the Petersons
traveled all over California meeting with neurologists, internists and
acupuncturists. Doug had MRIs, brain scans and neurofeedback tests
done. Last February, Doug's doctor suggested he go off Lipitor to see
if the drug was causing his health problems. After three weeks, the
symptoms persisted, so the doctor put Doug back on the pill. Since Doug
wasn't exhibiting the most common side effect, muscle cramps, and his
liver function tests came back normal, the physician was doublly sure
that Lipitor was not to blame.

Finally, last spring, a doctor in Pasadena suggested Lipitor could be
the culprit. Doug went off the drug in May, and since then his symptoms
have stopped their downward spiral and his health has slowly started to
improve. According to Karla, his mind is sharper, his balance is better
and his speech is more clear in the mornings, before he gets tired. But
he still has a long way to go.

"Before, I was a good father and family person," said Doug, who has two
children with Karla. "At this point, I can't do that much."

A former Navy diver and owner of Sierra Tahoe Computers, a repair and
service business, Doug has had to cut down his work schedule because of
his fatigue and loss of hand coordination. He is considering going on
disability, but Karla remains optimistic.

"We are hoping he is going to get better. That's our number one goal,"
she said. "Anger is a waste of energy at this point. We are trying to
recover and get the word out."

DID PFIZER DO ENOUGH STUDIES?

Since Parke-Davis (later acquired by Pfizer) developed Lipitor in 1997,
it has become the number one prescribed cholesterol-lowering drug in
the United States, with more than 18 million Americans having been
prescribed the drug. New York City-based Pfizer, the world's largest
pharmaceutical company, derives a quarter of its $32 billion in annual
sales from Lipitor, according to an article in SmartMoney. With sales
expected to top $10 billion this year, Lipitor is poised to become the
largest-selling pharmaceutical in history, surpassing Pfizer's other
wonder drug, Viagra.

Lipitor is proven to lower total cholesterol by 29 to 45 percent. As
with any prescription, it comes with a list of possible side effects,
such as muscle pain or weakness and liver dysfunction. Pfizer's Web
site states, "The most commonly reported side effects are gas,
constipation, stomach pain and indigestion. They are usually mild and
tend to go away." In a nine-month study of 2,502 patients, Pfizer found
that more serious side effects, such as facial paralysis, colon
inflammation and gallbladder pain, occurred in less than 2 percent of
those treated.

Pfizer was unable to commment on reported adverse side effects in time
for the Tahoe World's deadline.

The problem, say the Petersons, is that Pfizer has not conducted any
long-term studies. Doug's health issues didn't start for two and a half
years after he started taking Lipitor. Similarly, Tahoe City
psychologist John Altrocchi, 75, was on Mevacor for around three years
when he started to develop calf pain that became so severe he could
hardly walk. He also experienced a case of temporary memory loss called
transient global amnesia (TGA), which has been linked with statins. A
day after watching the 1998 Super Bowl game, Altrocchi had no memory of
the event.

"There's no way you could prove that Mevacor was responsible for the
TGA, but it's very possible," said Altrocchi, who stopped taking the
drug about three years ago and convinced his brother, a retired
neurologist, to go off Lipitor. "Especially for older men, I think it's
wise to get off statins right away. There is very little evidence they
do much good."

While most symptoms seem to start after a few years, Ed Ontiveros of
Homewood began having physical problems within 30 days of taking
Lipitor. After experiencing muscle aches and weakness for a few days,
the 75-year old fell in the bathroom and didn't have the strength to
get up. Since going off the drug, he's had no problems.

"It [reduced cholesterol] is not worth it with the side effects," said
Ontiveros. "You may not live as long, but you sure don't want to die
earlier."

Doctors are quick to prescribe Lipitor, says Karla, because they
perceive it as a magic bullet in the battle against cardiovascular
disease, the leading cause of death for Americans, and it's easier than
prescribing a long-term regime of healthy diet and exercise. But the
evidence that high cholesterol leads to heart disease is not
conclusive, said Altrocchi, and there is even speculation that
cholesterol provides protection for the brain and spine.

THE ROAD TO RECOVERY

The Petersons say Pfizer is too powerful to take on alone, but would
consider joining a class-action lawsuit against the company. However,
lawyers have told them a lawsuit is only possible if Lipitor gets
recalled by the Food and Drug Administration. (Another statin, Baycol,
was recalled by Bayor in 2001 after 31 people died of kidney failure
while on the drug.) The Petersons filled out a complaint on the FDA Web
page and encourage other Lipitor sufferers to do the same.

Frustrated by doctors who doubt the connection between Lipitor and
health problems, the Petersons are awaiting the results of a study
being conducted by Dr. Beatrice Golomb, a neurologist at the University
of California-San Diego, on the effects of statin drugs. As reported by
the Wall Street Journal this week, Golomb found that 15 percent of
statin patients developed some cognitive side effects. In the meantime,
the couple is focusing on Doug's recovery and staying positive.

"At this point, I consider myself lucky I'm not in a wheelchair," said
Doug, who is currently in phsyical therapy. "There are no guarantees in
life. Your birth certificate doesn't come with a warranty."

The kind of  memory loss  we have been discussing is
an artifact of aging for many.  Obviously there are things to be
wary about -- it can be a precursor of serious diseases if it
worsens.

The American Academy of Physicians suggests:

Aging may affect memory by changing the way your brain stores information
and by making it harder to recall stored information.

Your short-term and remote memories aren't usually affected by aging. But
your recent memory may be affected. You may forget names of people you've
met recently. These are normal changes.

So to be more accurate it is recent memory loss that is normal with
aging.  

Obviously, taking statins confounds the picture.  I've never said it
did not.

But I think when recent memory loss occurs, it gives one pause and one
wonders if one is developing Alzheimer's disease.

There is a difference:

The wonder of the brain is that if any of these events are of particular
interest to you, you may remember them for months, or years or even for the
rest of your life. But if an Alzheimer's patient is among us, who is even
in the early stages of the disease and even if he or she thinks that the
events are very important, it's very unlikely that they will remember for
more than a few hours and certainly not more than a few days.

As the disease progresses, the span over which Alzheimer's patients can
remember things gradually shrinks--from days and hours to minutes, then to
seconds and then to nothing. Unfortunately, this is not only a devastating
disease but an extremely common one. We estimate that it affects six
million people in the U.S. alone and costs 100 billion dollars a year.

My (slight) memory problems may or may not be attributible to statins. But if
they were, I would continue with the statins.

Bill,
If you continue to take statins, I hope that you will at least consider reading
"What You Must Know About Statin Drugs and Their Natural Alternatives" by
Jay S. Cohen, MD. When you get the book, read pages 86-90. Dr. Cohen
discusses memory problems on those pages and mentions some people (such as
Dr. Ulene) that now have very serious memory problems due to statins. I
would hate it if you developed serious memory problems.

This type of memory loss can be misinterpreted as coming from aging,
when it comes from statins. This is further confounded by the fact that
most people prescribed statins *are*....older.

To be accurate it is recent and short term memory loss, what we call
"working memory" which occurs from statins. And from Alzheimers. And
from aging.

Nor would I!

That's right. And sadly, those who have Alzheimer's do not recover.
Those who have statin induced memory loss usually recover, to varying
degrees depending on the individual, the dose of statin, length of
statin use and which statin was used.

A very good description of memory loss owing to with statin induced
memory loss, and statin induced transient global amnesia.

Some researchers estimate many people diagnosed with Alzheimer's have
been mistakenly diagnosed. Because as I have pointed out, the brain is
the same brain. There is no unique type of memory loss from statins.

Statin induced memory loss can reasonably be diagnosed by stopping the
statin for at least several months to see if the person recovers.

Sadly, this is not true with Alzheimer's which can only be diagnosed by
autopsy.

I thought the only controlled studies evidence of memory problems
from statins mostly had to do with longer term memory.
Specifically, there was a slight loss of the usual benefit
attributable between similar tests administered months apart. A
repeat of the study showed inconsistent results.

I don't think the studies indicate that; hear it is not so from
anecdotal reports, and can attest it is not so from my own experience.

My understanding of the Muldoon work is not from a reading of the study
but from reading Muldoon discussing the study in Neuropsychology of
Cardiovascular Disease (Waldstein et al).

Good description. I've always had memory problems, and they are a
bit worse now at 61 and pretty much as you describe. Overlaid on
my terrible memory is a slight loss of ability to recall on
demand, especially things from recent memory.

I do take folate, but I limit it to about 800 mmg awaiting further
evidence pro and con.

I did take folate for a short time, thinking it mattered in
cardiovascular disease protection for me; would lower my homocysteine.
It didn't lower it much.

When the study about folate and cancer came out I contacted the author.
He said he would not advise taking folate. I mused  that perhaps I
would drop to one mg from the five I had been taking.

He repeated his statement.

I was a bit taken aback, used more to reticence from researchers. That
conversation, further readings on this issue, and discussion here,
convinced me the homocysteine theory wasn't clear enough for me to
ignore the possible cancer risk. So I stopped using it.

As for memory; I have found I think better when I drink coffee
throughout the day rather than all in the moning, use raw cornstarch
and orange juice cocktails throughout the day, and for some time after
exercise, even though I am also then in a lot of pain.

It doesn't lower mine much either, even when combined with B6.

There is also the following, though I don't have the full text and
I'm not sure I understand the various relationships among DNA
methylation, MTHFR polymorphisms, and folate levels anyway:

J Laryngol Otol. 2005 May;119(5):371-6. Related Articles, Links  

 
Association between methylenetetrahydrofolate reductase
polymorphisms, alcohol intake and oropharyngolaryngeal carcinoma
in northern Italy.

Capaccio P, Ottaviani F, Cuccarini V, Cenzuales S, Cesana BM,
Pignataro L.

IV Clinica Otorinolaringoiatrica, Azienda Ospedaliera L Sacco,
Milan, Italy.

Folate metabolism dysregulation may lead to abnormal cell
proliferation and predispose to carcinogenesis by inducing DNA
hypomethylation. Folate pathways may be modified by polymorphisms
in relevant genes, such as that for methylenetetrahydrofolate
reductase (MTHFR), or by alcohol consumption. We investigated the
relationship between MTHFR mutations at nucleotides C677T and
A1298C, which cause reduced MTHFR enzyme activity, and
susceptibility to oropharyngolaryngeal carcinoma in 65 patients
and 100 controls. We isolated DNA from peripheral blood
leukocytes. In oropharyngolaryngeal carcinoma cases the C677T
heterozygous genotype was more frequent (p = 0.018), the allele
frequency of MTHFR 677T was greater (p = 0.019) and the genotype
677TT/1298AA was more frequent (p = 0.001). A higher risk of
carcinoma was found in the case of moderate drinkers with mutant
MTHFR homozygosis or double heterozygosis (OR = 21.2 and OR = 9.1,
respectively; p trend = 0.002), and the association was maintained
for the different cancer sites (glottic, supraglottic,
oropharyngeal). Our findings support the hypothesis that the
interaction of alcohol intake and MTHFR polymorphisms might
contribute to susceptibility to carcinogenesis of the
oropharyngolaryngeal tract.

And similarly:

5,10-Methylenetetrahydrofolate reductase polymorphisms and the
risk of pancreatic cancer.

Li D, Ahmed M, Li Y, Jiao L, Chou TH, Wolff RA, Lenzi R, Evans DB,

Department of Gastrointestinal Medical Oncology, Unit 426, The
University of Texas M.D. Anderson Cancer Center, 1515 Holcombe
Boulevard, Houston, Texas 77030, USA. dli@mdanderson.org

To test the hypothesis that 5,10-methylenetetrahydrofolate
reductase (MTHFR) polymorphisms modify the risk of pancreatic
cancer, we conducted a hospital-based, case-control study
involving 347 patients with newly diagnosed pancreatic
adenocarcinoma and 348 healthy controls, frequency matched by age,
sex, and race. MTHFR polymorphisms were determined using the
PCR-RFLP method. Association of these polymorphisms with the risk
of pancreatic cancer was estimated by unconditional logistic
regression analysis. We found that the C667T (but not the A1298C)
polymorphism had a significant main effect on the risk of
pancreatic cancer. The frequencies of the MTHFR 667CC, 667CT, and
667TT genotypes were 49.5%, 38.6%, and 11.9%, respectively, among
cases compared with 48.5%, 45.0%, and 6.5%, respectively, among
controls. Individuals with the 667TT genotype displayed a 2-fold
increased risk for pancreatic cancer compared with those with the
CC/CT genotypes [adjusted odds ratio (OR), 2.14; 95% confidence
interval (95% CI), 1.14-4.01]. Multivariate analyses found that
the effect of the 677TT genotype on the risk of pancreatic cancer
was present among ever smokers (OR, 5.53; 95% CI, 2.0-15.3) and
ever alcohol drinkers (OR, 3.16; 95% CI, 1.30-7.69) but not in
never smokers (OR, 0.82; 95% CI, 0.33-2.06) and never drinkers
(OR, 1.42; 95% CI, 0.56-3.62). Furthermore, a positive interaction
between the MTHFR TT genotype and heavy smoking or heavy alcohol
consumption was detected. The OR (95% CI) of pancreatic cancer was
6.83 (1.91-24.38) for heavy smokers among the TT carriers compared
with never smokers with the CC/CT genotypes and 4.23 (0.88-20.3)
for heavy drinkers with the TT genotype compared with nondrinkers
with the CC/CT genotypes. These observations support a role for
folate metabolism in pancreatic cancer, especially among smokers
and heavy drinkers.

And then a think piece:

Folate and its preventive potential in colorectal carcinogenesis.
How strong is the biological and epidemiological evidence?

Bollheimer LC, Buettner R, Kullmann A, Kullmann F.

Department of Internal Medicine I, University of Regensburg, 93042
Regensburg, Germany.

Based on a 15-year old hypothesis, it is believed that an adequate
ingestion of folate vitamins decreases, whereas a nutritional
depletion of folate increases the risk of colorectal cancer. The
present article reviews the efforts to provide biochemical and
epidemiological evidence for folate as a chemopreventive agent
against colorectal carcinogenesis. BIOLOGICAL EVIDENCE::
Tetrahydrofolates govern the intracellular one-carbon metabolism
and account for proper DNA biosynthesis and macromolecular
modification. Numerous experimental studies traced different
molecular pathways and tried to link folate depletion with DNA
instability and/or mutagenesis. However, none of the proposed
underlying molecular mechanisms appear clearly defined.
EPIDEMIOLOGICAL EVIDENCE:: Numerous case-control and prospective
studies have been conducted on folate and colorectal cancer, which
all together miss a clinical bottom line. The recommendation of
folate intake to prevent colorectal cancer is therefore not
evidence-based.

On the other hand, it looks like high dietary folate is good for
your prostate :-)

Dietary folate and risk of prostate cancer in Italy.

Folate status may affect cancer risk through its role in both
methylation and nucleotide synthesis of DNA. A low dietary intake
of folate has been linked to risk of several cancers, but
epidemiologic studies with reference to prostate cancer are
scanty. We therefore analyzed data from a case-control study of
prostate cancer conducted between 1991 and 2002 in various areas
of Italy. Cases were 1,294 patients with incident, histologically
confirmed prostate cancer and controls were 1,451 patients
admitted to the same network of hospitals of cases for acute,
nonneoplastic conditions. All subjects were < 75 years old. Intake
of folate and other nutrients was computed from a validated food
frequency questionnaire. We adjusted for energy intake using the
residual method, and calculated multivariate odds ratios (OR) and
95% confidence intervals (CI) using unconditional logistic
regression. The OR of prostate cancer was 0.66 (95% CI, 0.51-0.85)
for the highest versus the lowest quintile of folate intake. The
relation between dietary folate and prostate cancer was consistent
across strata of age, methionine, vitamin B6, and alcohol intake,
and did not vary substantially according to Gleason score of
prostate cancer. The combined OR for high-folate and low-alcohol
intake versus low-folate and high-alcohol intake was 0.46 (95% CI,
0.29-0.75). Therefore, this study supports a favorable role of
dietary folate on prostate cancer risk.

Yes I saw the first two as well, and couldn't even pronounce (make a
habit of not posting what I can't pronounce...).

As the study I posted up-thread mentioned (and that is not the
study/author I referred to regarding a private e-mail caution re
folate) there is cause for concern about supplementing, for everyone.

There may be justified application in certain cases, but I'll now wait
for the evidence.

I find it disturbing that many women will take the advice of a male
poster just because he's male. I have seen it happen over and over, to
the detriment of one who 'listened' last year, and now has disabling
peripheral neuropathy and mitochondrial myopathy from her 'recommended'
statin. I think this plays a role in many women's statin injury; they
are too quick to defer.

Biochemistry isn't my strong suit. A question I have about folate
metabolism is as follows:

It seems that folate reduces homocysteine, and I've seen the
metabolic pathways for that. But I also see that "antifolates"
such as the catechins (such as EGCG) in green tea (or
methotrexate, for that matter, I guess) can reduce homocysteine?
Does anyone here know how that happens?

In fact, sometimes I see reports that suggest both that folate
supplementation may be anti carcinogenic AND that antifolates may
be anticarcinogenic. What gives?

Re women and men. That's the well-known cross sex effect, at least
in part. I'm more likely to accept what a woman tells me.

Yes I agree; it's a 'cross sex effect. I was always 'listened' too very
closely when I was 25. Didn't much matter what I said.

Zee,
I bet I know the reason that people listened to you more when you were 25.
It's my guess that you are very pretty. It's natural for people (men and
women) to pay attention to pretty women that are below the age of 30. I
saw a television show where a really beautiful 20 year old woman dressed
up as a really obese woman that had terrible make up and glasses. The
camera crew followed around all day (including bars). People ignored her.
When the same woman dressed up in normal clothing and normal makeup--lots
of men and women started converstations with her. I learned a lot from
that show which is why I still remember it.

Elevated homocysteine is a marker for folate and or B12 deficiency. They
might be more sensitive than an actual B12 blood level as different
compartments have different concentration levels. You may have normal blood
B12 levels but be deficient in the CNS.
Taking a vitamin pill may or may not do the trick. B12 absorption involving
intrinsic factor and normal gastric function.
Sublingual or shots with high doses are really needed before one can make
any conclusions on the nature of homocysteine elevation.
