Vitamin B1 (Thiamine)
Vitamin B-1, otherwise known as thiamine, is necessary for most every
cellular reaction in the body as a participant in an enzyme system known
as thiamin pyrophosphate. It is vital to normal functioning of the
nervous system and metabolism. It can be found in meat, whole grains,
fish, and nuts.

Thiamine Helps
Hepatitis Patients
Giving the B vitamin
thiamine
(Vitamin B1) to patients with chronic hepatitis B infection
improves
signs of the disease,
a small preliminary study has found. This could point the way to a cheap
and nontoxic way of treating the infection.
Hepatitis B virus (HBV) is spread through contact with the blood or body
fluids of an infected person. HBV infects the liver, and in severe cases
can lead to cirrhosis, liver cancer and liver failure. HBV can be
treated with antiviral drugs and interferon, but
there is
no cure.
A
researcher decided to test thiamine for HBV after a very bright and
aware patient observed that his
aminotransferase
levels rose and fell depending on whether he was taking the vitamin.
High levels of aminotransferase enzymes indicate more active infection
of the liver.
Investigators conducted a trial in this patient and two others with HBV
infection to investigate the relationship. All had either failed
treatment with interferon or could not tolerate the drug.
While patients were on thiamine treatment, their
aminotransferase
levels fell from abnormally high to normal levels;
these levels increased when thiamine was subsequently withdrawn. And in
subsequent liver biopsies after thiamine treatment, HBV DNA was
undetectable.
This is the first study to investigate thiamine for treating hepatitis B
infection. There are several potential ways that the vitamin might fight
the infection.
For example, thiamine binds to iron and thus reduces the iron load in
the liver. Past studies have linked high iron levels in the liver to
more severe HBV infection, as well as a worse response to interferon.

Soy Formula Kills
Three Babies
The "Remedia" brand
of soy-based baby formula appears to have caused or contributed to three
infant deaths and illness among other babies.
The formula, which is
sold as a Kosher feed and is thought to be popular among Orthodox Jewish
communities in New York and other areas, did not contain enough vitamin
B1, which is vital to brain development. A company representative said
that tests have shown the formula contained at least 10 times less B1
than was advertised.
An investigation is
still underway to determine for sure whether the absence of B1 was to
blame for the deaths and illnesses. The product has been recalled in
Israel and parents who have fed their babies the formula are urged to
get them booster shots of the vitamin.
