Diagnosis and Testing / Breath Tests (UBT) / Re:
Acidity and Diarrhea after Pylori treatment
on: Jan 17th,
2008, 12:10am
Acidity can increase - usually temporarily - because some people with H.pylori have
low acid levels. After Hp is cured, as the stomach becomes healthier, it makes
normal amounts of acid. Then the patient may feel acidic especially if they have a
weak lower oesophageal sphincter and heartburn is felt (gastro-oesophageal reflux
disease - "GERD"). Acid blockers such as Nexium are the treatment at this stage.
The GOOD NEWS is that high acid levels probably protect from cancer of the

Diarrhea can occur - as a side effect of antibiotics. If there is blood visible in the
stool it needs to be investigated as sometimes a colon infection is the cause
(C.difficle bacteria). Usually though, diarrhea is only present while the antibiotics
are actually being taken. About 25% of people being treated for Hp have loose
stools temporarily.

It is timely to discuss chronic fatigue syndrome here. Hpylori is probably a cause
of CFS in about 20% of cases is my guess. In any case, eradicating Hp does no
harm. What casues the rest of the CFS cases? I don't know, but I am sure there
would be a Nobel Prize for the person who works out what is going on. As usual
with unexplained diseases, many theories exist and everyone has a treatment they
recommend for it. Stress is NOT relevant in my opinion. I have seen completely
mentaly normal unstressed people get it. The good news is that it is not fatal and
eventually improves.

Hi, there is some link between headaches and Hp. Check for it and treat it if
your child can take the treatment. Good luck.

After surgery - about half the people do not have H.pylori and about half do. You
can't tell if it is gone or not unless a test is done. If the germ is still present, then
you can get the ulcer back, but more importantly, you can also be at risk from
stomach cancer. So, your father should have a blood test for H.pylori. If positive
then he should take the treatment.

1. Breath Test
2. PYtest
3. <50 is normal, >200 is positive, >2000 is a typical high value.
4. No - Hp can exist without ulcers.
5. With the C13 breath test >3 is positive, >10 is typical. It is expressed in
complicated units - like %/100 above baseline (it is a very small change but the
instruments are very accurate).

on: Mar 5th,

Hi dog lovers;
The dog helicobacter is a different one from the H.pylori but I agree that humans
sometimes can catch it (so don't let your dog lick you on the face). I did treat
some cats once but actually I never treated dogs.
The treatment would be the same as the human treatment. Rather than
famotidine, a drug ike Prilosec (omeprazole) is preferred (acid pump blockers work
better). Give a high dose, plus a high dose of amoxycillin, and metronidazole. Add
pepto-bismol tablets if you can.
Someone should do a treatment trial on this. I will talk to my vet about that issue.

Basic Science / cagA - Cytotoxin associated gene / Re:
Hummingbird phenotype Cag A and fatigue
on: Mar 5th,
2007, 6:28pm
Hi Tanja.
CagA toxin is only an issue if the H.pylori is still present - most H.pylori do produce
the toxin so this feature is no big issue. The first thing to do in MALT lymphoma is
eradicate the Hp. After that, if Hp is gone from the stomach, then other MALT
sometimes disappears too.
But after you cure the Hp, it really cannot be doing any further harm. The fatigue
must be something else. Often, with fatigue, no cause can be found - but
endocrine testing is worthwhile (thyroid esp.).

Symptoms and Diseases / Dyspepsia / Re: H-Pylori,
colitis, enlarged spleen
on: Mar 5th,
2007, 6:20pm
Dear AmyLynn;
I recall that pain outside the stomach area is not usually caused by H.pylori. Weird
things such as tiredness and worsening of bowel symptoms can be influenced by
H.pylori though. So, when everything else is investigated, have a follow-up breath
test to see if the Hp is still there. If the bug is still present then careful choice of
treatment will be required as it will be resistant to several antibioticws by now.

Symptoms and Diseases / Weird Diseases and
Syndromes / Re: Ammonia smell
on: Mar 5th,
Dear Weirdsyndrome;
Ammonia, if it comes from H.pylori (in the stomach) would be absorbed in the gut
and removed by the liver. If it was being produced in the stomach, the acid would
turn it into ammonium ions which are rather harmless. This means that it is
unlikely that the ammonia smell would be from H.pylori. I think there must be
some other explanation. There is a lot of literature on ammonia but I don't recall
ever seeing a patient who smelled of it. Maybe you are the first. To lower
ammonia, I suggest you decrease the amount of protein you eat (i.e. meat) and
drink plenty of water. In any case, eradicating the H.pylori is stll a wise choice.
Try to find a gastroenterologist or infectious disease person who has an interest in
H.pylori. You may be a unique case!

Back pain can be from a duodenal ulcer but this would heal with teatment for
H.pylori - so the pain should go.
Remember that H.pylori symptoms from the stomach are separate from acid
refux symptoms higher up. Therefore they can change independently. For acid
symptoms treat as required with drugs like Omeprazole or Zantac. I mention the
latter one because it does not interfere with follow-up breath tests after H.pylori

This is an interesting study on the face of it. However, it needs to be
validated in some way. If the data were true then a simple prospective study of
persons with asymptomatic therapy taking a brief course of amoxycillin and herbs
would be worthwhile. Amoxy vs Herbs vs both. No need for endoscopy - just
breath tests before and 1 month after. I must say that I am skeptical.

Re: Reproduction of H.pylori

Hp reproduces by binary fission as do all bacteria. It nips in the middle and the
new organism sprouts flagella from its end. The two cells then stay together for a
short time, looking like a "U" shape with flagelle on each of the top ends.

Re: How does H.pylori survive the stomach?
on: Jan 15th,
2007, 8:00pm
Hi there. When first swallowed, Hp enters a stomach with acid juices, but usually
the stomach is actually empty so that both sides - both stomach walls - are
touching each other. So you see it does not need to swim very far to reach the
mucus layer. In the normal juice there is enough urea (2.0 mMol) to allow Hp to
make some ammonia so that it can buffer acid nearby. Thus it survives long
enough to reach the safe environment under the mucus. Interestingly, after the
infection is established, Hp uses all the urea in the stomach so that new
Helicobacters coming down probably have a much harder time surviving!

Pregnancy Families Kids Pets etc. / Pregnancy, Allergy,
Children etc. / Re: Adopted 19 Mo. Old Children Have H.
on: Jan 12th,
2007, 4:23pm
Hi there. I have seen a few "russian adoptee" stories over the years. If little
children have Hp then parents and other (USA born) siblings can be infected. It is
well known that mild iron deficiency and slight growth retardation are associated
with Hp. The issue is - how hard is it to treat in small children? It is somewhat
difficult because they don't take the medications easily. That is why it is useful to
be aware of it, in case something crops up. I would suggest that the rest of the
family is tested for Hp, then if anyone becomes unwell from Hp (caught from the
kids) then you can be more pro-active. Otherwise, be aware of the issue and
ready to treat the kids when they are older, or if they develop stomach problems.
The reason why asymptomatic people are usually left alone is that no-one (i.e.
governments/insurers) wants to bear the cost of screening and treatment of "well"
people. When it is yourself, and your family, you may feel differently and be quite
prepared to spend the $150 or so involved. In these forums you will see lots of
stories by sick people who were never tested for Hp and are now rather cross
because they were so much better after having it taken care of. In Australia I
recommend that all immigrants are tested for Hp in their first health checkup. We
breath test the whole family sometimes.

Hi, I read the gory details of your discussions. Yes, you can get a breath test to
do your self. It is not a big product for us but one can be mailed and you can send
back a balloon of breath sample. Cost isabout $100 all up I expect. Maybe
contact Dr Aruni Mendis PhD. Tri-Med sells the Kimberly
Clark test but in Australia it is available without prescription.
I will be forwarded replies to this post so that I stay in the loop.

You should have the boyfriend tested as you both may have it. Yes, you can catch
it back but mostly you don't. Make sure you have a breath test one month after
treatment to prove that the Hp is gone.

Catching H.p. / Dirty Water and Fecal-Oral / Re: Lake
Water and Sewage
on: Nov 11th,
The only way to provethat the Hp cames from the water is to show that your Hp
has the same DNA as Hp in the water. This is not really practical since there are
many strains of Hp. A second way is to have a blood sample taken a few weeks
before you went to the lake and show that antibodies to Hp were not present at
that time.

Culture your own bug by swallowing some string and then pulling it back out
after 1 hour. The device is called Enterotest - you may be able to buy just one.
How tough are you? See papers by Samuels re string test culture. Try this link

Well, if you are HP positive, then culture your own HP! Fast after midnight
then swallow some string (90 cms long) with water. After 1 hour pull it out and
culture it on Skirrow's plates. It should work. Read a paper by first author

Did my HP come from my cat?
on: Feb 12th,
Sorry, don't blame the cat. We think cats can catch HP sometimes from the
people! Some cats have been found to have HP but usually cats have their own
special one and it is not the same as human HP (it is less vicious).
I have a Siamese cat which I think has cat HP. She is always hungry but vomits if
we feed her too much. I think she has cat gastritis and cat helicobacter. One day
I may feed her some Pepto-Bismol and antibiotics but it seems such an effort.
Here is a picture of our cats - the one on the left passed away last year from cat
cancer - aged 11 years. The one we still have (on the right) is fat and lazy, and
very mean to our dog. Sigh..

Great question. Yes, it is likely that the secret gnomes in Astra-Zeneca,
Glaxo-Smith-Kline and Chiron are examining the physical structure of vacA on
expensive computers with 3D goggles and 36 inch LCD screens, even as we speak.
Luckily, their work is secret so we need not be influenced by their rigid concepts
and are free to come up with completely new wacky ideas about the action of
vacA. Heh heh!

Good news for you! Dogs have a dog helicobacter which can infect humans
but only rarely. If you let your dog lick you on the mouth all the time then it could
H.p. probably takes at least three days to cause symptoms. Breath tests for H.p.
should be able to detect the presence of the dog H.p. if you caught it. Don'y
worry at present, it was probably just a stomach virus.
