Steven L. - 02 Apr 2008 23:19 GMT
Dr. Tichenor of New York is advancing a new theory of chronic sinusitis:
 It may be caused by previously unsuspected infestation of mycobacteria.

Abstract presented at the 2008 AAAAI meeting:

Non-Tuberculous Mycobacteria (NTM)) as a cause of Chronic Rhinosinusitis

W. S. Tichenor, M. D.
New York, New York

Non-tuberculous mycobacteria (ntm)) as a cause of chronic rhinosinusitis

JC Walsh, WS Tichenor The Center for Allergy, Asthma and Sinusitis, New
York, New York

Rationale: Patients with chronic rhinosinusitis have persistent symptoms
despite medical and surgical treatment. Current theories regarding
causation include immunological reactions to fungi and bacteria, but
there is no consensus regarding the cause. Since mycological causes have
been investigated previously, NTM could also be a cause.

Methods: Endoscopically directed cultures of all patients with chronic
resistant rhinosinusitis were reviewed. Most patients have cultures done
for mycobacteria. Those with positive cultures for NTM were selected.
Treatment records were then reviewed.

Results: Twenty-one patients grew out NTM from either the ostiomeatal
unit or paranasal sinuses. Nineteen grew out Mycobacterium chelonae and
1 each of M. majoritense and M. immunogenum. Eighteen of 21 patients had
previous sinus surgery and 19/21 used nasal irrigation. Based on
sensitivities, patients were typically treated with a combination of 3
antibiotics: amikacin irrigation, an oral quinolone, and clarithromycin.
Treatment time ranged from 6 weeks to 13 months. Eleven patients
responded to treatment, 2 were not treated, 1 received inadequate
treatment, 2 remained culture positive, 2 did not respond, 2 were lost
to follow-up, and 1 responded but was treated at the same time for MRSA.
There were negative follow up cultures on 14/19 patients.

Conclusion: Patients with chronic rhinosinusitis resistant to treatment
should have endoscopically directed cultures performed for NTM.
Treatment is often successful with an extended course of multiple
antibiotics.

Eek. Based on what I've heard of the results from the widespread
treatment of postal workers with quinolones during the 2001 anthrax
scare, chances of adverse side-effects from a 13-month course of any
quinolone are very high. If courses that long are required for many
patients, the cure may be worse than the disease.

No, one recovers spontaneously from quinolones.
(which ARE my Least favorite antibiotic, they cause nausa, dizziness,
and the symptoms of arthritis.)
but over a few months one returns to normal.

Unless one lucks out big time with the pahges, untreated sinusitis is
forever.

Oh BTW the quinolones are almost a specific for impedeing the ability
of piliated bacteria like e-coli to penetrate cells.  They don't
really kill them, but without the ability to access the inside of the
next layer of cells down, they fall off when their old host cell layer
does.

Mycobacteria are among the toughest bugs to treat.  Their cell walls are
able to resist many common antibiotics, and even common antiseptics.
Several different antibiotics may need to be given simultaneously.

What Dr. Tichenor has NOT yet done is prove that the introduction of
mycobacteria into a patient (lab animal) can induce sinusitis in a
previously healthy specimen.

And until he is, who the heck knows if the mycobacteria are the real
cause of sinusitis.  They could be a coincidental accompaniment of the
real cause.

Quinolones are actually the one type of anti-biotic that I refuse to
take. The reason being that I tend to acquire a sort of over-awareness
of my own heartbeat that hasn't completely subsided over a year later.
One of the listed side effects is heart fibrillations which I assume
is somewhat connected to what I experienced, but a less than severe
case. I understand that this wouldn't be the situation with everyone,
but let it be known that there are large online communities, much like
this one, for the suffers of quinolone side-effects that can take
several years to subside.

Just a word of warning...

Not to mention running off to a doctor to dose yourself with meds on the
strength of the latest hot theory of sinusitis--a theory which usually
has a half-life of a few years.

Five years ago, Dr. Tichenor was utterly convinced that the Mayo Clinic
theory of Allergic Fungal Sinusitis was correct, and prescribed
amphotericin irrigation as a matter of course.

But Accentia's commercial amphotericin wash just failed clinical trials.
 So now Dr. Tichenor has glommed onto this other theory.

And so it goes.

Maybe we should wait another 5 years before running off to treat this
hypothetical mycobacteria infection that Dr. Tichenor claims we've all
got up our noses.

Yeah some people prefer to run off and have the delicate internal
airflow modulating structures of their nasal cavity carved out. Than
have it redone every three years.

Lab animals like chinchillas?
Palmer at UPenn proved that bacterial  biofilms cause ostia media
using chinchillas 5 years ago.

" ...the introduction of mycobacteria into a patient (lab animal) can
induce sinusitis in a previously healthy specimen. ..."

The abstract below says infection occurred after the inadvertent
introduction of  Mycobacterium chelonae  -- does any one have easy
access to a full text to see if the infection is described and if it
was like, or became, sinusitis? -- interesting that the source was a
biofilm.

Hospital outbreak of atypical mycobacterial infection of port sites
after laparoscopic surgery.
Vijayaraghavan R, Chandrashekhar R, Sujatha Y, Belagavi CS.
Department of Laparoscopic Surgery, Rajmahal Vilas Hospital,
Sanjaynagar, Bangalore, India. wetware@sify.com
J Hosp Infect. 2006 Dec;64(4):344-7.

   A series of 145 laparoscopy port site infections due to
Mycobacterium chelonae were found in 35 patients following laparoscopy
at a single hospital over a six-week period. The contaminating source
was ultimately identified as the rinsing water used for washing
chemically disinfected instruments. The organism survived and grew
within the biofilm at the bottom of disinfectant trays and within the
outer sleeves of re-usable laparoscopic instruments. Remedial control
measures included changing to ethylene oxide gas sterilization of
laparoscopic equipment instead of chemical sterilization, thorough
dismantling and manual precleaning of instruments, drying prior to gas
sterilization, and random checks of environmental samples within the
operating room complex for acid-fast bacilli. No further atypical
mycobacterial infective episodes have occurred in the three years
since the study. Awareness of this ubiquitous opportunistic organism
that is not easily eradicated from the hospital environment, careful
surveillance, detailed attention to disinfection methods of medical
devices, and appropriate control measures are essential to prevent
potential outbreaks.
PMID: 17046106

The following suggests that prior to 1999 mycobacteria chelonae
infections were unknown to the literature, other than in the
immunocompramised:-

Initial report of primary sinusitis caused by an atypical pathogen
(Mycobacterium chelonae) in an immunocompetent adult.
Spring PM, Miller RH.
Department of Head and Neck Surgery, M.D. Anderson Cancer Center,
University of Texas, Houston 77030-4009, USA. pspring@mdanderson.org
Ear Nose Throat J. 1999 May;78(5):358-9, 362-4.Links

Primary sinonasal infections caused by atypical mycobacteria are rare.
In fact, only four examples of a primary nontuberculous mycobacterial
etiology of paranasal sinusitis have been cited in the literature. The
patients in all these cases were infected with the human
immunodeficiency virus and, by definition, they all had acquired
immunodeficiency syndrome. We present a report of an immunocompetent
adult with a history of chronic sinusitis who consistently and
repeatedly manifested a fast-growing, nonpigmented, atypical
mycobacterium of the Runyon group IV category: Mycobacterium chelonae.
The patient was successfully treated over a 3-year period with a
combination of antimicrobial agents, multiple limited endoscopic sinus
surgeries, and eventually a total globe-sparing maxillectomy. At this
time, the patient is disease-free and has received no further
treatment. This case represents the first report of an immunocompetent
adult host with a primary atypical mycobacterial infection of the
paranasal sinuses. It also demonstrates the multimodal nature of the
treatment of atypical mycobacterial infections. We also discuss the
Byzantine classification scheme relative to atypical mycobacteria, the
disease process in the immunocompromised host, and the various
treatment options.

Mycobacterium chelona was  probably unknown in the literature because
it is finiky, requires a special culture medium and/or a PCR to find
it, which only became available in like 2003? but it is ubiquitous.

Oh and did I mention that it likes a lower temp than other bugs?
30C for it, thank you, so it just does not show up in the standard
set.

A while back, there was a theory going around that mycobacteria causes
Crohn's disease. It was worked on for some time, and then just
disappeared.

I remember this.
Summary Transmissible spongioform enchephalopathies (TSE's), include
bovine spongiform encephalopathy (also
called BSE or "mad cow disease"), Creutzfeldt-Jakob disease (CJD) in
humans, and scrapie in sheep. They remain a
mystery, their cause hotly debated. But between 1994 and 1996, 12
people in England came down with CJD, the human
form of mad cow, and all had eaten beef from suspect cows. Current mad
cow diagnosis lies solely in the detection of
late appearing "prions", an acronym for hypothesized, gene-less,
misfolded proteins, somehow claimed to cause the
disease. Yet laboratory preparations of prions contain other things,
which could include unidentified bacteria or
viruses. Furthermore, the rigors of prion purification alone, might,
in and of themselves, have killed the causative virus
or bacteria. Therefore, even if samples appear to infect animals, it
is impossible to prove that prions are causative.
Manuelidis found viral-like particles, which even when separated from
prions, were responsible for spongiform STE's.
Subsequently, Lasmezas's study showed that 55% of mice injected with
cattle BSE, and who came down with disease,
had no detectable prions. Still, incredibly, prions, are held as
existing TSE dogma and Heino Dringer, who did pioneer
work on their nature, candidly predicts "it will turn out that the
prion concept is wrong." Many animals that die of
spongiform TSE's never show evidence of misfolded proteins, and Dr.
Frank Bastian, of Tulane, an authority, thinks the
disorder is caused by the bacterial DNA he found in this group of
diseases. Recently, Roels and Walravens isolated
Mycobacterium bovis it from the brain of a cow with the clinical and
histopathological signs of mad cow. Moreover,
epidemiologic maps of the origins and peak incidence of BSE in the UK,
suggestively match those of England's areas of
highest bovine tuberculosis, the Southwest, where Britain's mad cow
epidemic began. The neurotaxic potential for cow
tuberculosis was shown in pre-1960 England, where one quarter of all
tuberculous meningitis victims suffered from
Mycobacterium bovis infection. And Harley's study showed pathology
identical to "mad cow" from systemic M. bovis in
cattle, causing a tuberculous spongiform encephalitis. In addition to
M. bovis, Mycobacterium avium subspecies
paratuberculosis (fowl tuberculosis) causes Johne's disease, a problem
known and neglected in cattle and sheep for
almost a century, and rapidly emerging as the disease of the new
millennium. Not only has M. paratuberculosis been
found in human Crohn's disease, but both Crohn's and Johne's both
cross-react with the antigens of cattle
paratuberculosis. Furthermore, central neurologic manifestations of
Crohn's disease are not unknown. There is no
known disease which better fits into what is occurring in Mad Cow and
the spongiform enchephalopathies than bovine
tuberculosis and its blood-brain barrier penetrating, virus-like, cell-
wall-deficient forms. It is for these reasons that
future research needs to be aimed in this direction.

I found this bit preticularly interesting.

Amyloid: the common denominator in all
spongioform encephalopathies
"It is an astounding finding, because we never
would have dreamed that amyloid and prions are
the same", proclaimed Stanley Prusiner [1].
In the past amyloid was usually the deposition
that took place due in the course of chronic inflammatory
disease, mainly tuberculosis, the usual
precipitating cause. The very term "amyloidosis",
coined by Virchow, was a misnomer, assuming that
the infiltrative material had chemical similarities
to the starch (or amylum) of plants, which it did
not. Nevertheless, by force of use and habit, the
word stuck.
Hass's study proved a direct correlation between
amyloid deposition and the mycobacteria by
injecting M. bovis into rabbits and following M.
tuberculosis in humans. He concluded that the only
infectious disease which served as an apparent
cause of amyloidosis was tuberculosis [59]. All
21 human subjects with amyloid in Hass's investigation
had chronic pulmonary tuberculosis. In a
50-year study based upon autopsy, Schwartz saw
amyloidosis, primary and secondary, in the brain
and elsewhere as a by-product of underlying infectious
tuberculosis, either reactivating itself or
being reactivated by a host of traumatic, chemical,
biologic or physical insults [60]. Microscopically, in
the brain, Schwartz found plaques and amyloid
degeneration of nerve fibrils.
When Schwartz injected 22 guinea pigs with
M. tuberculosis, all but four came down with
amyloidosis. His uninfected controls, with the exception
of one showed no amyloid. He thereby
confirmed Hass, who's large series of rabbits
showed that three out of four inoculated with
bovine tuberculosis had amyloid disease within 15
months [59]. Hass's amyloid uniformly showed a
principal protein fraction as well as a minor fraction
whose physical behavior also implied another
protein.
The amyloid issue had surfaced previously
when in 1978, Researcher Pat Merz, in breakthrough
work, identified tiny fibrils in the brains
of scrapie infected mice not present in well
controls. Prion purists refused to admit that their
prion rods were related to Merz's find, citing her
entities as longer fibrils and claiming that Merz
stated plainly that her scrapie associated fibrils
(or SAF) were not amyloid and therefore could
not be prion rods, the term Prusiner used for
amyloid fibrils. Actually Merz said that her Scrapie
associated filaments were amyloid-like on
more than one occasion and workers in the field
suggested that the two entities in Merz and
Prusiner's papers were identical [1]. Delgado saw
such fibrils in either case as typical features of
amyloid [62].
Meanwhile, by 1994, de Beer, studying the relationship
between a major rise of serum amyloid
and having tuberculosis, saw a rapid descent in
amyloid in patients treated with anti-tubercular
drugs [63].
As an offshoot of de Beer's work, Tomiyama
dissolved b-amyloid plaque with rifampin, a first
line drug in the treatment of TB, and one of the
few agents, to this day, that is able to dissolve
amyloid plaque [64].
