How
Shall We Disagree?
(With each other and with
our patients)
by Milt Hammerly, MD
"A Randomized, Double-Blind
Trial of Nystatin Therapy for the Candidiasis Hypersensitivity Syndrome,"
was published 12-20-90 (NEJM 1990; 323:1717-23). The first sentence of
the editorial comment (NEJM 1990; 323:1766-1767) is as follows, "Few illnesses
have sparked as much hostility between the medical community and a segment
of the lay public as the chronic candidiasis syndrome." The last sentence
of the same editorial is, "Additional scientifically sound studies will
be needed to determine whether this syndrome does or does not exist, and
if it does, what the optimal treatment is for patients."
A vigorous rebuttal to my
article on "Candida Overgrowth Syndrome" (COS) was anticipated. You can't
expect to broach this, or other, controversial subjects without drawing
a strong response. It was no random act of foolhardiness or masochism that
prompted me to take on this subject. That some physicians would disagree
with me is less important than how they disagree. Questioning my logic
and my evidence is entirely appropriate. Constructive debate is healthy
-we can all learn from it. Questioning my intelligence, motivation and
ethics and that of the administration that hired me is inappropriate. Hostile
disagreements rarely change anyone's mind - we are all demeaned by them.
This is in fact what many patients face when they try to talk to their
physicians about CAM. Patients' beliefs in CAM are often belittled by physicians
who convey the following message, "It's bogus because I say it's bogus.
After all I am a scientist and you are not. What medical school did you
go to?" Guess what? Those patients will either not talk to their physician
again about CAM or they will find another physician! In either case the
patient suffers because they lose the benefit of potentially useful medical
guidance and oversight and the patient-physician relationship is compromised.
As a profession we are guilty of being unprofessional in how we disagree
with each other and with our patients. Is it any wonder that the studies
consistently show that patients don't tell their physicians about their
use of CAM?
Set aside the issue of COS,
for the moment, and let us imagine a patient who comes in with a bunch
of subjective symptoms and suspects they have "bogusemia"
which can only be treated by "quackicillin." The easiest
and most natural response in this situation is to categorically discredit
the patient's beliefs based on the fact that bogusemia and quackicillin
are not taught in medical school nor approved by the FDA. Unfortunately
there is no good research on bogusemia or quackicillin that you can quote
that disproves them so the patient has to take your not so humble word
for it. The next easiest, and somewhat unnatural, response is to patronize
the patient and give them a placebo, perhaps even quackicillin if it's
harmless. The most difficult response is to disagree without belittling
or patronizing. Explaining to the patient that other treatable conditions
might cause the same symptoms as bogusemia and you are not comfortable
with this diagnosis unless you have ruled out other possible causes and
there is some objective evidence for bogusemia allows both you and the
patient to respectfully disagree. The patient-physician relationship is
strengthened and the appropriate evaluation and treatment are facilitated.
If by chance you stumble on a patient that does appear to have objective
evidence of bogusemia and who in turn has a favorable response to quackicillin
then you can risk your reputation and share this experience with your professional
peers. Those who agree with you will call this a case report. Those who
disagree with you will call it an anecdote. Those who are intellectually
curious don't care what it's called, they simply want to do a study to
see if there's anything to this. Those who are infuriated by your suggestion
that in some cases treatment of bogusemia with quackicillin may be appropriate,
but who lack objective evidence to refute your position will resort to
personal attacks to discredit you and if possible see to it that you are
ostracized, fired or burned at the stake for voicing such blasphemous heresy
against the precepts of flat earth medicine. Eventually the appropriate
scientific research is done and the truth is known. In some cases bogusemia
and quackicillin are discredited and become forgotten in the ash heap of
medical history. In some cases bogusemia gains respectability and becomes
"newdxemia" and quackicillin becomes magically transformed
into "eurekacillin."
Many CAM diagnoses and treatments,
including COS, are described by the above illustration. With respect to
COS it is usually diagnosed without a shred of objective evidence and treated
with a variety of untested interventions, some benign, some potentially
dangerous and none verified by research. The 1990 NEJM study did no objective
testing. The inclusion criteria were entirely subjective. What were they
treating? Your guess is as good as mine. I agree with the observation that
total serum immunoglobulins are meaningless from a diagnostic point of
view, have never stated or implied otherwise and don't use these in my
clinical practice. The assertion that candida antibodies are totally worthless
is an opinion that is not supported by research. The patient I described
had "off the scale" candida IgA antibodies >400. The laboratory reports
that 60 % of patients have readings less than 25, 32% have readings between
25 and 100, 8 % have readings >100 and less than 1% have readings >400.
To say that this laboratory result is meaningless when it is greater than
20 standard deviations above the mean is statistically ludicrous and clinically
irrational when the patient had a dramatic response to antifungal therapy
after years of not responding to other interventions. The patient had every
appropriate conventional medical test in her work up and none of the medical
interventions tried had any significant effect on her symptoms. The tests
were either negative or inconclusive. At no point have I ever or will I
ever suggest or imply that a diagnosis of COS somehow nullifies any other
conventional testing, diagnosis or treatment. While there is much interesting
research on how to diagnose and treat fungal infections no good research
has been published regarding COS. This is precisely why I submitted a research
proposal to Pfizer Pharmaceuticals last August to study this question in
detail. Several physicians have expressed an interest in participating
in this research. I welcome the input and participation of any physician,
especially skeptics, in this and other projects to research CAM controversies.
Until we have definitive answers
we are dealing in the realm of opinion. It seems fewer facts promote stronger
opinions. Until we have answers we should learn to disagree with more gentility
and less hostility. Learning how to disagree with patients and with each
other will benefit everyone. The rapid growth in the use of CAM therapies
means that we will have and more and more opportunities to disagree with
our patients. If we disagree with civility and objectivity we can continue
having the privilege of patients trusting and valuing our advice. If we
use hostility to convey opinions not founded in facts we will lose the
opportunity and privilege of positively impacting our patients' lives.
When you consider the 380% increase in the use of herbal medicines by patients
since 1990 and the estimated 15 million adult patients who are having potential
interactions between their prescription medications and OTC supplements
(JAMA 1998;280:1569-1575) it becomes very apparent that we need to keep
the lines of communication open! |
