Here's a nice summary of the bacterial genesis of (some) peptic ulcer
disease. See Frank Forman's comments below.
Certainly J. Robin Warren (pathologist) and Barry Marshall (gastroenterologist)
from Perth, Australia are deserving of this landmark discovery. Marshall's
self-experimentation by giving himself a serious case of gastritis when he
drank the H. pylori is one of a long series of physicians and
self-experimentation. The first cardiac cath was done by a physician on
himself, with the help of his nurse.
In medical practice, however, the problem with H. pylori is not nearly as
straightforward. The Helicobacter pylori surrounds itself in an "antacid"
capsule so that it can live in the stomach. In older populations, it's found
in about 50%. Obviously not all these persons have peptic ulcer. It seems to
be more prevalent in societies where sanitation is poor. Treatment to
eradicate Helicobacter pylori with antibiotics is expensive and not without
risk--allergic reactions, antibiotics induced diarrhea etc. And if patients
with symptoms-- heartburn, abdominal pain-- but no ulcer are found to have H.
pylori, there's a less than 50% chance that they'll improve with antibiotic
So, this discovery didn't put the pharmaceutical people out of business.
To make this more complex: much peptic ulcer disease and symptoms relate to
the use of anti-inflammatory drugs-- All the NSAIDs ( non-steroid
anti-inflammatory drugs) such as Ibuprofen, Aleve and others and aspirin can
cause peptic ulcer and gastrointestinal bleeding. The COX-II inhibitors Vioxx
( now removed from the market) and Celebrex are no more effective as
anti-inflammatories, they just have less irritating effects on the stomach.
I did some work with colleagues in the early 1960s documenting the effect of
aspirin on the stomach lining and published the first photographs of the
aspirin induced lesion. ( This wasn't a new discovery as an English observe in
1937 had published similar findings and documented with an artist's drawing, as
photography through the gastroscope wasn't available at that time. Now, the
fact that aspirin can cause ulcers and GI bleeding is an accepted fact both by
physicians and laymen. You can read it on the labels which come with the
When we published our work we had similar reactions to that of the Australian
workers with H. pylori.
Here's the progression of acceptance of new knowledge:
* It doesn't happen
* If it does happen, it doesn't happen very often
* It does happen often, but it isn't very important
* Yes, it happens often, but it's not new!
For some really good information on H. pylori and ulcer disease, search
Google. Put in H. Pylori + patient information. You will be referred
to the National Library of Medicine and get some solid information which
is in clear understandable English.
After all that preamble-here's the article
Nobel Came After Years of Battling the System
Frank Forman write:[William Weedon taught a terrific course called "The
Concepts of Order and Disorder in Science and Literature" (we didn't get into
literature at all. Too bad!) in the tool school at UVa, which I took in 1965-6.
He remarked that the phlogiston theory of heat was "abandonded much too
quickly," meaning, I took it, that the caloric theory of heat was far from
being adequately established. This doesn't seem to be the case here.
[I cannot help but be reminded that Galileo implored the Roman Catholic priests
to look into his telescope. They refused. A replica of that telescope is in the
Air and Space Museum, across the street from where I work. It has been rigged
to show the moons of Jupiter. The telescope wobbles so badly and the image is
so small that the priests very well might not have been convinced. I can't say
for sure I could see the moons myself!]
