Arthritis and Glucosamine in the news
2006-09-30 13:35:52Hi, here's some info on arthritis and glusosamine in the news, hope
its somewhat informative. Also I have a question, I hope someone can
offer some insight...in this article near the end it states that
people who are diabetic need to discuss with doctor before taking
glucosamine. There is a possibility that I may be diabetic, I will be
getting tested this week, I do use glucosamine and it works well for
me. Does anyone know if there are any contradictions with using
glucosamine and being diabetic, and if so why? Thanks.

Arthritis and Glucosamine
Everyone's talking about the dietary supplement
glucosamine. Some people swear it helps their
osteoarthritis, while others report no benefit. A
new study hopes to find the truth.
Ask an osteoarthritis sufferer what the newest
arthritis drug is and there's a good chance they'll
mention something that isn't a drug at all.
Glucosamine is a natural, glucose-like molecule,
found in all animal life forms, but some arthritis
patients are calling it a new miracle cure.
Glucosamine has been studied since the late
1950s in Europe and there is growing evidence
to suggest that it may be an effective treatment
for the arthritis caused by worn or damaged
cartilage.
Taken in capsule form, glucosamine, which is
extracted from the outer covering of shell fish,
appears to work by providing the body's
cartilage-forming cells with the basic building
blocks to enable it to repair and maintain itself.
Cartilage was once thought of as an inert,
Teflon-like substance coating the ends of our
bones that once worn or torn, was beyond
healing. As we now understand it, cartilage is a
highly active tissue. Although cartilage suffers
from wear and tear, we now know that it can
also repair itself. Cartilage is almost unique
amongst body tissues in that it has no arteries,
veins or nerve supply. Instead, its health is
dependent upon the liquid which exists between
the cartilaginous surfaces, called synovial fluid.
More than just a lubricant, this synovial fluid
feeds the cartilage and, more importantly,
removes worn out particles.
In osteoarthritis, the synovial fluid becomes thin
and loses its nurturing and shock absorbing
powers. At the same time, the cartilage becomes
worn, roughened and eventually breaks down.
This in turn exposes the ends of the bones in
the affected joint and allows them to rub
together, resulting in inflammation and pain. For
many people with osteoarthritis, encouraging
the body to repair its own cartilage seems to
equal a reduction of the pain and swelling of
arthritis.
Supplementing the depleted synovial fluid has
been used to relieve arthritis symptoms. This
treatment is often described as viscose
supplementation therapy and is marketed under
the brand name Synvisc. What might loosely be
termed synthetic synovial fluid is injected into
the affected joint to replace loss of the natural
substance. In fact, these injections consist of
hyaluronan, a key ingredient of natural synovial
fluid. Boosting it in this way restores its
elasticity, viscosity, shock absorbing powers and
nutritional properties.
This treatment consists of a series of three
injections which in some cases can provide
excellent relief for up to six months. While it is
not a cure, it is a very logical therapeutic
approach. It is interesting to note that while it
takes three to seven days for an injection to
take effect, often months after the hyaluronan
has broken down, the joint still remains
improved. This suggests that it may work as a
nutrient, helping the cartilage regenerate. The
downsides to this treatment are the cost, the
fact that it must be administered by a physician
and the temporary effect.
The next step would appear to be to identify a
substance that could encourage the body's own
synovial fluid to become replenished which in
turn would continually nurture and regenerate
the cartilage. Researchers are hopeful that
glucosamine may turn out to be such a
substance.
As a result of the intense interest about this
substance, a double-blind study is currently
being conducted on glucosamine hydrochloride
at Mount Sinai Hospital in Toronto. Double-blind
research involves two equal groups of people -
one takes glucosamine hydrochloride and the
other takes placebos (sugar pills) but none of
the participants know which group they are in.
Results of this work should be available in a few
years. This study is being followed by a series of
animal and human studies in the United States.
The safety level of glucosamine seems good. It
occurs naturally within the human body and
there have been no reports of significant side
effects in the world literature since studies
began in 1950. Although glucosamine is
available over the counter in pharmacies and
health food stores, no one, particularly people
with diabetes and pregnant women, should start
taking it without discussing it with their doctor.
Glucosamine has not been linked with
interactions to any other medications, so you
don't have to stop taking your NSAIDs or other
necessary drugs. Anecdotal reports are very
positive, but not everyone appears to benefit, so
it's important to work with your doctor and not
abandon other anti-inflammatories without
consultation.
Glucosamine can be purchased at almost any
pharmacy or health food store. Be careful,
however, that you are in fact buying
glucosamine. There is no support for the addition
of any other agents into glucosamine
preparations. As well, some confusion may arise
in that there are two main forms available on the
market: glucosamine sulfate and glucosamine
hydrochloride. The majority of the European
work was carried out with the sulfate, purely
because funding was available for this form.
Chemically, both break down into glucosamine in
the stomach, but more of the active ingredient is
available with the hydrochloride as the sulfate
has to be stabilized with filler. If at all in doubt,
talk to your pharmacist first. The standard
dosage of glucosamine is 500 mg three times a
day.
No one really knows yet exactly how
glucosamine functions and who it's best for, but
as many physicians will tell you, it's certainly
worth a try!
Dr. Alan L. Russell is the Director of the Brampton
Pain Clinic.
Osteoarthritis news The effectiveness of
glucosamine is under investigation at the Mount
Sinai Hospital, in Toronto, and until the trial
results are available the benefits of this
substance remain unproven, says Dr. Arthur
Bookman, Medical Advisor to The Arthritis Society
of Ontario. Yet there are some recent research
findings that are worth noting.
-One more reason to lighten the load. Weight
does effect the development of osteoarthritis of
the knee. More weight equals more stress on
the joint, and that has a direct impact on
osteoarthritis.
-Get thee to a physiotherapist. The weakness of
thigh muscles correlates with the amount of pain
experienced from osteoarthritis of the knee.
Strenghthening the thigh muscles helps to
reduce joint stress.
-Go easy on the stomach. Acetaminophen works
as well as ibuprofen for osteoarthritis of the
knee and gives less stomach irritation as well.
-Take the long way home. Regular walking and
exercise programmes improve the ability to walk
faster and for greater distances.
-Good news for truck dodgers. Running does not
cause osteoarthritis of the knee.
Brand awareness
Pharmacist Sherrie Hertz provides the following
cautions when purchasing glucosamine or any
other natural product.
-Look for products which have been prepared
according to internationally recognized
standards. These will be labeled "standardized".
-Check that the product you buy has an expiry
date and that it's still fresh.
-Some natural products have been given a Drug
Identification Number or DlN. If you see this on
the label you can be sure that you are indeed
getting the full amount of product specified.
-Remember that the quality of natural products
may vary greatly. Wild herbs, for instance, are
sometimes difficult to properly identify and must
be gathered by someone familiar with their
differences.
-Potency will depend upon a variety of things
such as soil conditions, climate and genetic
diversity within the plant itself.
-If you have any doubts about what to
purchase, ask your pharmacist
