AT THE MEETING
AMERICAN ACADEMY OF ALLERGY, ASTHMA, AND
IMMUNOLOGY, MARCH 14-18, 2008
in the Feb. 2008 volume, JACI)
- Dexamethasone (Decadron) is
mentioned in Abstract #3. This oral and
injectible corticosteroid is important as the only such medication
(since Celestone – Betamethasone – became unavailable for oral use)
which is effective in patients who have become unresponsive (“steroid
resistant”) to prednisone and methylprednisolone. It
is especially useful in some of our asthmatic patients.
- The measurement of exhaled Nitric
Oxide is finally approaching clinical availability in the
evaluation of inflammation in bronchial asthma and chronic bronchitis –
asthma variant. It compares well with
other measures of inflammation. See
Abstracts # 123, 292, 605, 612.
- Abstract 20 notes a positive correlation
found between early onset asthma and adult respiratory
- The subject of generalized reactions
to allergy immunotherapy injections, although real, is often
presented in overwrought fashion. Abstract
# 101 suggests pretreatment with anti-histamines…which I discourage as
giving a possibly false sense of security. Strict
adherence to safe protocol results in very rare reactions.
Such reactions are discussed in Abstracts #481 and 549.
- Allergic reactions to foods
are the subject of numerous abstracts: a) most reactions in children
occur in school, not in buses - #106; b) RAST, puncture-prick,
intradermal and patch testing are discussed in #400; c)
casein-containing chalk may be the reason for increased asthma in
milk-allergic children in school - #714; d) one can be allergic to goat
and sheep milk without being allergic to cow’s milk - #716; e) the
issue of histamine in wine is discussed in #’s 746, 908, and 910; f)
cross-reactions between peanut (a legume) and nuts…in addition to the
problem of manufacturing proximity…are discussed in #936; g)
desentization for milk allergy is discussed in #’s 962 and 982; h) oral
desensitization to peanut and milk is discussed in #’s 530,531.
- There is an increased risk of invasive
pneumococcal disease in the presence of allergic disorders -
- The “Atopic
March” is alive and well: a) atopic dermatitis is often the
firstr step, and its clearing may not alter the march to other allergic
manifestations - #126; b) the use of probiotics in infancy
seems to lower the occurrence of allergies - #129; c) the potential of
Rituximab (anti-CD-20) is discussed in #138; d) exclusive breast
feeding for four or more months is protective - #144.
- Omalizumab (Xolair) is the
topic of several abstracts: a) possible use in insulin allergy - #150;
b) in hyper-IgE Syndrome - #341; c) has no effect on T-cell responses -
#446; d) reasons to discontinue - #537; e) improves quality of life in
asthma - #592; f) is being used in patients with IgE over the currently
stipulated maximum of 700 - #845. This
approach to dealing with the underlying cause of atopic
allergies (IgE) continues to be a distant second to properly evaluated
and implemented allergy immunotherapy. But
at least, finally, asthmatic patients of Pulmonologists are getting
some attention to this basic matter.
- Eosinophilic Esophagitis has
been re-discovered: a) diagnosis is by biopsy, and correlates well with
presenting symptoms = #;s 169, 177; b) dysphagia is a common presenting
symptom, often secondary to major motor disturbance of small muscle
function - #’s 271,273; c) it may present in various ways - #285; d)
these patients should be tested for food sensitivities - #’s
- Concomitant use of nasal decongestants
and nasal steroids is discussed in #215. I
- Systemic reactions to percutaneous
skin testing reportedly occurs in 3.5% of patients, for which
the prompt administration of epinephrine is useful - #223.
- Subcutaneous IG is a more
convenient and also effective mode of administration, as compared with IVIG - #230.
- SSRI anti-depressants do not
affect histamine wheal size – 234.
- Long-term use of inhaled nasal steroid
(over 3-4 years) appears safe in children and adolescents - #235.
- Wheezing Rhinovirus infection in early
childhood predisposed to later asthma - #’s 240,561.
- Known for many years, diesel exhaust
exposure has both early and late effects, and increases the
likelihood of asthma (think school buses!) - #’s 252,253.
- Abstract # 262 discusses protocols for desensitization
to retuximab and other chemical agents.
- Sublingual desensitization is
experiencing a revival of interest, although I don’t believe it is yet
ready for prime time – #’s267, 370, 493.
- Allergy Immunotherapy is very useful
in children, although I find it rarely necessary below the age
of 5 years - #289.
- Genetics in Asthma occurrence
and progression are discussed in #297.
- Positive ANA is correlated
with lack of proper control in asthma - #298.
- The use of pulmonary function testing,
which I find very useful in determining adequacy of actual – vs
clinical – control – is discussed in #311.
- Immunodeficiency: a) this
should include isolated IgA deficiency - #331; b) CVID is associated
with recurrent purulent infections and reduced lung function - #339; c)
a new IVIG (Privigen) is discussed in #’s 634,635.
- Peanut Sensitivity; a) efforts
at rush desensitization (not recommended by me), #’s
370,371,375,528,529,532; b) “may outgrow”, #567; c) associated with
increased risk of other food sensitivities, especially if the
reactivity is severe - #’s932, 976.
- Hereditary Angioneurotic Edema
can be treated with replacement of C1-esterase inhibitor (#380) and by
use of fresh frozen plasma (#383).
- Chronic Urticaria:
a) when associated with autoimmune disease (#396),
and b) may be treated with (Xolair), with which I have no experience
(#’s 566, 872).
- A form of Lactobacillus, another
probiotic, may be useful in decreasing the asthma response -
- Therapy of
asthma: a) remember Cardiac Asthma - #621; b) there is too
much use of ICS /LABA therapy vs ICS mono-therapy, leading to increased
mortality…a point with which I agree, given the propensity for the
development of tolerance to excessive use of beta adrenergic therapy -
#’s 551, 596; c) early screening and diagnosis is vital to effective
asthma control - #609; d) s-Tryptase in induced sputum is correlated
with increase in eosinophiles and with increased severity of asthma -
#806; e) HSCRP may be a useful marker for persistent inflammation in
asthma, although it does not correlate with exhaled Nitric Oxide of
local eosinophile count - #760; f) staphylococcal enterotoxins may play
a role in asthma severity - #765.
- As we have learned
more pointedly in recent years Vitamin D plays an
important role in many metabolic functions in addition to bone health. This is all the more important given the fact
that many if not most people are deficient in this vitamin. Abstracts #
555 and 752 note that low levels in patients with bronchial asthma
contribute to increased exacerbations and to problems with bone health.
- The existence of a
“naso-ocular reflex” prompts the use of nasal inhaled
steroids for ocular symptoms - #582.

Corticosteroids: a) no growth retardation in children younger
than six years, but growth must still be monitored - #602; b)
concentrated usage (2X, 4X) during exacerbations reduces symptoms and
reduces need for oral steroids - #842; c) indications for reducing or
eliminating ICS are discussed in # 844.
Sensitivity: a) # 613 describes bronchial and oral challenge
tests; b) NSAID reactivity is becoming increasingly common - #727; c)
aspirin desensitization is described in # 737; d) extra-respiratory
reactions are discussed in #747.
- Regarding Pneumovax,
pre-immunization antibody level reduces response, but does
not eliminate it.
those patients with elevated IgE are improved on Xolair -
#668, probably reflecting combined disease with bronchial asthma.
Syndrome and Toxic Epidermal Necrolysis are very serious systemic
diseases, usually caused by drug reactions, especially
anti-epileptic medications - #’s 724,733,743.
- For Penicillin
testing, both major and minor determinant materials may be
available from Kaiser-Permanente in California - #740.

ipratropium, cromolyn, or acetylcysteine.
- The use of aminophylline remains controversial especially for
younger physicians, but continues to be usefuhas in this case for
children with acute asthma. It is still part of our armamentarium.

idiopathic urticaria and angioedema. It may or may not work in this
- Item 1201: Reports that upon discontinuation of Xolair therapy,
clinical symptoms reemerged and correlate well with reducing Xolair
concentrations. Thus, the reduction in Xolair dose after 6 months of
treatment cannot be recommended, and Xolair treatment is certainly not
a substitute for properly applied allergy immunotherapy, which
progressively reduces IgE which in the majority of patients leads to a
true desensitization and ultimate discontinuation of allergy
- Helicobacter pylori infection has been found to be a triggering
factor of attacks in patients with HAE, and treatment of this infection
causes the reduction in the frequency and severity of the reactions.

occur in patients with hereditary angioedema that may precede an
exacerbation by hours or days. This can include rash, a flu-like
illness, and paresthesias.
- Human seminal plasma allergy in woman is rare but can be serious.
This study finds that the prostate specific antigen is the causative
- Abstract #68. Treatment of diabetic patients with insulin may
produce anti-insulin antibodies with several different effects. One
type includes typical allergic reactions; the other type has to do with
neutralizing antibodies, which can produce both hyperglycemia by
blocking insulin effect and also hypoglycemia by binding to insulin
acting as a reservoir and then releasing the insulin at inappropriate
times. When this problem is refractory to treatment with steroids, it
may be successfully treated with intravenous immunoglobulin

of intravenous methylene blue.
- Abstract #137. Describes a single day aspirin desensitization
- Frequency of aspirin hypersensitivity in atopic patient is 10
times higher than the average population.
- Stevens-Johnson syndrome is a systemic adverse reaction to drugs
with severe cutaneous manifestations. It involves particularly certain
classes of drugs such as NSAID, allopurinol, anticonvulsants,
antibacterial, and sulfonamides. This is a case of a carbonic anhydrase
inhibitor reaction, namely acetazolamide.
- Abstract 158. Reports a rare case of allergy to multiple local
anesthetics, that is to groups 1 and 2, possibly via an IgE mediated

ABSTRACTS OF PAPERS PRESENTED AT
ALLERGY. ASTHMA AND IMMUNOLOGY
62ND ANNUAL MEETING
MARCH 3-7, 2006
2) "The high prevalence of sub-clinical
asthma ... supports the soundness
of recommendations to evaluate allergic rhinitis patients for asthma".
It has been estimated that 40% of patients presenting with allergic
have or will develop bronchial asthma.
3) Asthmatic children are not well able to
recognize reductions in lung
function and therefore do not appropriately use Albuterol. Therefore,
measures should be used in children, such as peak expiratory flow
4) Vascular Endothelial Growth Factor
(VEGF) is highly expressed in
the airway of asthmatic child patients and is responsible for increase
13) Exercise-induced bronchospasm is found
to a greater degree in obese
32) Other abstracts provide evidence that
omalizumab (Xolair) is effective
in use in moderately to severely affected asthmatics. It is also
useful as an add-on treatment to concurrent allergy immunotherapy.
two thirds of patients respond to Xolair therapy.
40) However, anaphylaxis to Xolair can
occur even after prolonged successful
treatment has been in effect.
43) Adult height in children treated with
inhaled Budesonide is reached
markedly later than in healthy children. This has been noted before,
that children using inhaled corticosteroid have a delay in their growth
but no total reduction in their growth.
76) Anti-TNF agents have revolutionized
the treatment of some arthritis.
However, it can be associated with side effects including endocarditis.
This has been found to more likely to occur in patients with
high titer ANA.
91) Formaldehyde, a widespread domestic
indoor pollutant, has been shown
to increase the risk of childhood asthma through a significant increase
in bronchial hyper-reactivity.
98) A form of occupational asthma caused
by styrene in an auto body
shop is reported.
99) Clarinettist's Cheilitis is reported
due to allergic reaction to
the cane reed.
118) Reports cases of lady bug hyper sensitivity among residence of
homes infested with lady bugs.
127) Cross-reactivity was noted among
almond, peanut and other tree
nuts, possibly extending to sunflower, pine nut, walnut and pecan.
any patient allergic to peanut or to a tree nut should essentially
intake of nuts in general, partly because of the common production
for packaging of these nuts and also peanuts. Peanut allergy associated
with high household exposure to peanut in infancy is reported in
140. The message here is to delay an infants exposure to peanut for a
time. However, no special effect of maternal consumption during
or lactation was observed.
145) We learn that sesame may be the
"Middle Eastern peanut, since it
is an essential nutrient of the Middle East diet and can be responsible
for serious allergic reactions.
158) We learn that approximately 25% of
children with cow's milk allergy
tend to outgrow their allergy by the age of ten years.
166) We are reminded that most food
anaphylactic reactions are due to
"hidden" allergens. Milk is the most common allergen among children and
can be encountered as casein in many foods.
183) Immediate allergic reactions after
ingestion of cooked mushrooms
correlate the finding of reaction between mushrooms and some molds,
190) Reports cases of scurvy associated with oral allergy syndrome
resulting from elimination of the related important foods from the
Therefore, vitamin C supplementation is required.
222) Reports that patients with nasal and
pulmonary allergic symptoms
should be questioned about gastrointestinal symptoms, since there is an
association in children with eosinophilic esophagitis .
239) Is important since it looks at the
possible relationship of tumor
necrosis factor and severe asthma. TNF-alpha can induce both
and activation of neutrophiles and eosinophils. It has been found to be
increased in the airways of severe asthma.
304) We are reminded that infantile eczema
is a predictor of asthma
in pre-school children. However, it is not associated with asthma
330) We learn that breast feeding for at
least twelve weeks and the
absence of being overweight appeared to play synergistic roles in
33l) We learn that elevated body mass
index at age three predicts wheezing
at age five independent of wheezing earlier in life. Thus, the
evidence of relationship between obesity and asthma.
339) Early life exposure to maternal
stress is associated with development
Several abstracts discuss the affect of
sublingual immunotherapy. The
reports are conflicting; and generally this is not yet accepted.
350) We are reminded that close self
monitoring of asthma symptoms with
peak expiratory flow meter increases children's awareness of their
status, leading to earlier intervention to avert asthma episodes.
371) Reminds us of a serious complication
of chronic steroid treatment;
that is, steroid myopathy. In the case presented, the manifestation was
restrictive lung disease.
376) Reminds us that stable asthma should
be associated with gradual
reduction in inhaled corticosteroid use. This of course should be
with pulmonary function tests before and after bronchodilator, to
possible occult bronchospasm.
425) Reports the clinical syndrome of
specific antibody deficiency (SAD)
in children, an immune deficiency characterized by normal
levels and antibody responses to protein antigens, but impaired
responses to polysaccharide antigens. It is fairly commonwith a
of 15% in children with recurrent infection without another defined
deficiency. It is also associated with allergic disease, which suggests
that it may be part of a more general disorder of immune regulation.
478) In abstract 478 we learn
sulfasalazine medication, usually used
for ulcerative colitis, is beneficial in the treatment of recalcitrant
chronic idiopathic urticaria.
479) In abstract 479 we review hereditary
angioedema. The typical symptoms
include abdominal attack (occurring in 97% of the patients) and also
swellings including extremity, facial, genital and trunk. Treatment for
this condition continues to include long-term andrigen therapy, which
to be safe.
489) We review mastocytosis syndrome,
which can be localized cutaneous
or progress to systemic forms.
508) We learn of adverse reactions to orthodontic appliances in
523) Reports delayed anaphylactic reaction
to immunotherapy injection,
delayed for over two hours and requiring abundant immediate epinephrine
536) According to this abstract, there may
be a direct association between
RSV infection and patients with family or person history of atopy.
576) We find another use for Singular;
namely, refractory vulvovaginal
pain and itch. Singular significantly improved these symptoms.
602) Reports that a history of paternal
asthma and allergy appears to
confer an increased risk for allergic sensitization in pre-school
to a greater extent than similar maternal histories.
603) We learn that asthma symptoms under
two years of age are much more
common following birth Meconium Aspiration Syndrome.
647) We learn that nasal corticoid
steroids reduce adenoidal size in
children with allergic rhinitis.
756) Reports on the safety of continuous
high dose nebulized levalbuterol
in children with severe bronchial asthma. In this studv, potassium.
and heart rate were followed in comparison with racemic Albuterol.
800) Reports that in one per cent of
patients receiving influenza vaccine.
significant chest pain occurred as a side effect.
859) Is the first report in the English
literature of a case of anaphylaxis
to topical benzocaine.
866) Reports that the use of beta blockers
does not affect the performance
of penicillin skin testing. The issue of concomitant beta blocker use
skin testing and allergy immunotherapy is a relative contraindication
not a strong one in our experience.
884) Describes serum sickness-like
reactions following placement of
885) Describes contact allergic reaction
to inhaled budesonide, but
not to other inhaled steroids.
919) Describes something that we have
recognized for decades; that is,
the classification between IgE and non IgE mediated atopic dermatitis.
These are two separate conditions carrying the same name. They must be
distinguished for proper diagnoses and treatment.
927) Describes contact dermatitis to
lanolin masquerading as chronic
957) Reports no.n-immediate reaction to
iodine contrast media.
979) Gives more evidence for the important
association between diesel
fuel exposure and the development of allergy, since this exposure
Th2 cell recruitment. It will be recalled that the hygiene
involving early exposure to infections and other endotoxin-containing
works to push Th2 cell reactions toward Thl cell reactions, thereby
the incidence of atopic allergy.
982) Describes the importance of cytokines
in allergic inflammation,
particularly IL-5 and IL-13.
986) Reports that IL-13 is particularly a
critical mediator of allergic
inflammation and therefore may be a target for therapeutic
1000) Reports on the issue of exposure to
mercury in fish, in vaccines
and possibly in dental amalgam, and its relationship to TH-2 driven
1009) Benzalkonium chloride as a
preservative in saline nasal sprays
impairs nasal mucociliary clearance. "Due to development of modern
devices, it is obsolete to use this preservative in nasal solutions."
should remember this.
1021) We have some de ja vu wherein the
report is that the immunologic
effect of specific immunotherapy includes stimulation of the
TH-1 response and induction of an allergen specific non-IgE antibody
primarily characterized by IgG4. This is something that those of us who
have been trained in the field have known for many decades.
1024) Reports on ths safety of allergic
immunotherapy in systemic lupus
1062) Reports that children that undergo
adenoidectomy and tonsillectomy
are likely to experience a significant improvement in their asthma
1068) Reports on the use of macrolide
antibiotics in the management
of asthma since these antibiotics have known anti inflammatory
in addition to their known antimicrobial activity.
1137) Reports the positive impact of
breast feeding for at least 8 months
in protecting from and reducing the prevalence of allergic disorders.
1146) Reports a patient who developed
allergic rhinitis and asthma due
to manipulation of wax moths as part of sport fishing.
1147) Reports that the prevalence of atopy
is higher in obstructive
apnea syndrome in children.
1149) Reports paralytic shell fish
poisoning caused by ingestion of
associated toxins and algae the west coast of Florida, including red
blooms. The differential diagnoses here includes pufferfish and

syndrome wherein isolated symptoms
are most commonly due to melon. However, systemic reactions are
commonly due to peach.
1164) Reports a high prevalence of
sensitization to tomato although
most sensitized subjects are asymptomatic. There are a number of
involving eosinophil esophagitis.
1176) Reports on the relatively mediocre
treatment of anaphylaxis in
emergency rooms, mainly due to the under-use of epinephrine and
In fact, abstract 1178 recommends the availability of two epi-pens to
properly acute severe allergic reactions.
1182) Reports a priming mechanism with
regard to the development of
insect sting anaphylaxis, either associated with prior sting or with
testing. There are a number of abstracts discussing venom

PEARLS from Abstracts of papers to be presented
18-22, 2005 at the annual meeting of the American Academy of Allergy,
(Published in the Journal of Allergy and Clinical Immunology, Vol.
115, No. 2, Feb. 2005)
- In children with established bronchial asthma (eg. three
or persistent long-standing dry cough), inhalational steroids
better started early. (#4)
- Combinations of medicines continue to appear, the newest
being Budesonide / Formoterol (inhalation steroid and long-acting
(#8). These may be convenient, but I prefer to use and titrate
individual components as needed.
- Minocycine (minocin) has been found to be
But the potential side-effects preclude, in my opinion, its use in all
but the really difficult cases...which become much less difficult if
are treat comprehensively, including with Allergy Immunotherapy.
- Xolair (the anti-IgE agent) is useful for, and should be
for, only the severe cases. Again remember allergy immunotherapy,
often ignored...especially by Pulmonologists.
- "All that wheezes is not asthma". And all asthmatics
same. See Abstract #23 regarding asthma phenotypes.
Being able to categorize asthma patients genetically, with treatment

It's not that complicated. It's just that too many pediatricians,

the Hygiene Theory). Atopic
cells produce less IL 10 and IL 12, this leading to more Th2

- Mycoplasma and Chlamydia pneumonia organisms are
58% of exascerbations of bronchial asthma. The Macrolide
(Biaxin) is a good antibiotic for such infections. Zithromax

One mechanism of action by which these infections worsen asthma is
an increase in cytokine production.
- One important theme this year, amplifying on similar concerns
in recent years, is the increasing finding that some asthmatics do
respond to appropriate treatment with inhalational cortico-steroids
(and the spectrum of other medications used for this condition).
The reason for this is unclear, but the result is a progressive decline
in lung function over years despite such treatment.
once again no mention is made of the use of allergy immunotherapy,
only treatment that addresses causal agents instead of effects.
This treatment should be an integral part of the comprehensive

- Many studies show that parents, physicians, and sometimes even
chronically under-estimate the severity of the patient's asthma.
This is serious...and can be fatal.
- Viral infections are responsible for over 80% of asthma
In chronic asthmatics and especially in patients with COPD, however,
bronchial tree may be chronically colonized with bacteria. Thus,
when an exascerbation becomes associated with purulent mucus discharge
over 12-24 hours, appropriate antibiotics are indicated.
- There are several conditions that can mimic asthma, known
of "pseudoasthma": vocal cord dysfunction; rhinitis; GERD, chronic
post-viral cough, hyperventilation, and obstructive sleep apnea.
These should be distinguishable by means of a thorough medical and
hostory; but pulmonary function testing - with or without methacholine
challenge - may be necessary. In addition, many patients have
several of these conditions simultaneously. One of the most
combinations include bronchial asthma, allergic rhinitis, GERD and
sleep apnea. This latter condition is very important and should
be missed. Please see information and a questionaire on that
in another section of this web-site.
- Exclusive breast feeding of an infant for
four months of life has been found to reduce the later incidence of
asthma in childhood.
- Inhalation cortico-steroids must always be a part of the
of anything but mild, sporadic asthma. Thus, any asthma
on two or more days per week warrants this approach. Furthermore,
treatment with these agents must be constant and not "as needed" in
to be effective.
- Persistent, "refractory" asthma warrants re-evaluation

Non-responsiveness to prednisone and to methyl-prednisolone can often

The latest pearls from Allergy Abstracts, 2003,
The Journal of Allergy and Clinical Immunology, Vol.
111, No.2, February 2003.
This year's crop of Allergy Abstracts - and the forthcoming
papers in the JACI - break some new ground and contain some clinically
applicable advances to the treatment of allergies, bronchial asthma and
related diseases. The following are subject areas and brief
which will require a deeper dive to obtain real benefit regarding areas
of personal interest.
In addition to the above, the following "pearls" are offered from
personal experience (over 40 years in practice in this field - and
- There are many articles regarding the proven effectiveness of Allergy
Immunotherapy ("shots, desensitization") for a variety of allergic
problems, notably allergic rhinitis and bronchial asthma
- The uses of leukotriene receptor inhibitors like Singulair
to include allergic rhinitis and chronic sinusitis in addition to
asthma, in children as well as in adults (#10,313).
- The safety of orally inhaled steroids in children

as compared with Allegra, Claritin and Clarinex.(#14). It
is best for allergic rashes and itching. And all are much better
than Benadryl for effectiveness and for side-effect profile.
- Simple saline irrigation of the nasal passages
Spray) is effective in reducing nasal congestion, not only in dry
conditions but throughout the year. (#23). "Try it. You'll
- Chronic Rhinitis and Sinusitis in children is
recognized as a significant problem, both in its own right and as
to accompanying or later bronchial asthma. But it must be thought
of to be diagnosed, by procedures including allergy evaluation,
for immune deficiency and for ciliary dysfunction, and ENT
- Anti-Ig E, in the form of Omalizumab and Xolair, has
the research labs and is entering the clinical realm, despite practical
shortcomings. Stay tuned. (#54,295,299,534).
- The central importance of mold sensitization (in
and cockroach emanations in urban settings) is clear - even without
the toxic molds (Stachybotyrum) that are beginning to create havoc in
homes and businesses throughout the country. (60,92,287).
- Toxic mold infestation can be insidious and pervasive,
only water damage and darkness added to the building practices of the
25 years, and leading to generalized, vague but very troublesome
and impairment, including cognitive impairment. It is
to diagnose and to treat. But prompt and thorough mold
in an affected structure can be very effective. (#92,548,549,712).
- A large variety of allergic reactions to medications,
other agents are reported.
Bottom line: anything can cause an allergic reaction in a
individual...even anti-histamines and cortisone.

gloves can go a long way to mitigating this problem in the workplace
- In some patients with exercise-induced anaphylaxis, often

- Tacrolimus and related agents (Protopic, Eladil) are proving to
addition to the treatment of atopic dermatitis and also other
long-term safety appears to exist also (#244, 352).
- More uses for the "black box" called IVIg (an immunomodulator
uses) are reported (#289,668).
- It has now become evident that, although ACE inhibitors are the
associated with angioedema, ACE Receptor Inhibitors also can
have this adverse effect (#394).
- Aspirin desensitization, around since the mid-1980's, is
resurgence of interest for some patients with Aspirin sensitivity
of its very useful anti-inflamatory effects. But it must be
under a specific and carefully-controlled protocol - because aspirin
can kill! (#410).
- The special case of pruritis in the course of hemodialysis is
in Abstract #435).
- Of course, chronic urticaria, the bane of patient and physician
is represented (#453,674).
- Peanut allergy, very dangerous, was discussed under anti-IgE

The above developments, expanded minute by minute throughout the
world, represent one of the reasons why some of us are “hooked” to our
chosen field. This also represents the reason why we call what we
do the “Practice of Medicine”: we’re always practicing!
- IL 4 and IL 5 both contribute to airway inflammation in bronchial
by promoting airway eosinophylia through a mechanism of suppressing
- IL 18 may be an important non-invasive inflamatory marker of
being higher with active disease.
- Exhaled nitric oxide (NO) is such a marker, although it is not
NO plays a harmful or beneficial functional role.
- Lung function is not a good predictor of “health related quality
- HRQL”; this reflects the substantial variability from patient to
regarding tolerance to bronchospasm, shortness of breath and consequent
hypoxia. Particularly dangerous to themselves and to their
are those patients with a high tolerance. They must be identified
promptly and watched closely, both clinically and with frequent peak
flow testing. See also Abstract 2-36.
- Both local and systemic responses to inhaled lipopolysacchride
endotoxin), ubiquitous contaminants of our environment, were found to
inversely with atopic status. These chemicals are now considered
immune modulators that may be the explanation behind the paradox called
the “Hygiene Theory”. “...some, but not all, the effects in LPS
want to be examined and used for treatment of atopic disease in
Abstract 2-13, p36. Of course, this is what many of us allergists
trained in the use of “stock bacterial vaccine” were achieving for
- until the FDA took the product off the market as being “without proof
of efficacy”. Too bad. But maybe....
- One article supports the use of the telephone for evaluating
in our asthmatic patients. We have recognized and used this for
- Several articles reflect the often poor treatment asthmatic
and often adults - get in emergency rooms.
- Abstract 2-23 points out that the presence of pets in the house
children is associated with an increased incidence of childhood
Thus, having pets is not the way to get the benefits of the “Hygiene
in our opinion.
- Abstract 2-27 is entitled “Reasons for Pediatrician
Asthma Guidelines”. Really! These physicians as a
generalists in the care of children, frequently “don’t know what they
know”. They certainly do not make proper use of specialists and
specialty guidelines for the care of their patients. It pains me
to say this. But I, and my patients who were referred
by their mothers, have experienced it all too often...and have had to
up the pieces. See also Abstract 2-46, and the note below.
- Now there is some evidence that pre-born children with atopic
may benefit - not only from maternal pre-natal diet manipulation - but
also from maternal pre-natal environmental control. Abstract 2-29.
- The benefits of inhaled levalbuterol (Xopenex) over racemic
are outlined in Abstract 2-34. My patients and I can
attest to that. It is to be hoped that an appropriate oral
may be developed soon. See also Abstracts 6-14,15.
- Abstract 2-39 addresses the long and increasingly common
experience of non-allergic,
non-asthmaticchildren and adults developing a viral respiratory
infection that produces wheezing and related dry cough. If not
early and aggressively, sometimes requiring not only inhalational but
oral steroids and other medications, it can be the beginnning of years
of asthma. These conditions are called “acute asthmatic
and “post-viral hyper-reactive airways syndrome”. Some of
incriminated viruses include RS virus, rhinovirus and coronavirus.
Some specific bacterial infections, including Mycoplasma and
pneumonia, may be especially associated with asthmatic responses
with chronic bronchial asthma. Abstract 2-42.
- Non-invasive predictors of asthma control, both generally and
of inhaled steroids, include sputum eosinophilia and exhaled NO.
- Dexamethasone may be a better steroid for short-term asthma
prednisone, with fewer side effects and shorter dose schedule.
- “Airway Responsiveness in Early Infancy Predicts Asthma,
and Respiratory Symptoms by School Age”. Abstract 2-46.
No, you don’t wait until “the kid outgrows it”. You evaluate,
and treat it appropriately from the beginning.
- The relationship between bronchodilator overuse (and
underuse) and mortality from asthma is addressed in Abstract
This is a very big problem, and physicians are generally not dealing
- Abstract 2-51 deals with those serious asthmatics who, despite
treatment, progress on a down-hill course through the years, as
by deterioration on serial pulmonary function
This is undoubtedly a heterogeneous group of patients. But the
denominators to dealing with this issue include: complete and accurate
initial diagnoses, including a search for underlying atopic disease
even where inapparent, and including a search for serious upper
disease; comprehensive medicinal treatment, clearly understood by
the patient; insistence upon adherence to treatment and
total and permanent discontinuation of tobacco use; regular
of pulmonary function tests to detect those patients who - although
controlled - demonstrate high-grade airway reversibility...and
continuing active airway inflammation; and comprehensive
of any underlying atopic activity with allergy immunotherapy, the
form of modulation which deals with causes and not only consequences.
With this approach, it is the very rare patient with bronchial asthma
whom I cannot demonstrate improved or at least stable lung function

they enhance the benefit to be derived from inhaled steroids when used
- Similarly, adding a long-acting inhaled B-agonist (Serevent or
to a regimen including an inhaled steroid produces better results than
even doubling the steroid dose. This combination is also more
than is either chemical alone. This relates directly to
and possibly to reversal of “airway remodeling”, as reflected in
of the basement membrane with types 3 and 5 collagen and related
activity, hyperplasia and hypertrophy of smooth muscle, goblet cell
- There are two types of croup in children: one associated with
related to RS virus infection); and the other not associated with

come. Abstract 2-56.

- Several mechanisms are proposed for the established efficacy of
immunotherapy in modulating - desensitizing - allergic sensitivities:
of blocking IgG antibodies; reducing CD-4 cell helper activity or
stimulating CD-8 cell suppresser activity to effect the
reduction in specific IgE levels. To these must now be added the
promotion of rapid apoptosis (cell death) of Th2 lymphocytes when
- after immunotherapy - with specific antigens. Abstract 3-6.
- The Hygiene Theory has produced a debate regarding whether the
of pets in the house (specifically cats) is beneficial or detrimental
atopic infants and children. (See Abstract 3-14). I, for
believe that the probable beneficial effects of early exposure to
pollution, infection and other sources of endotoxin can be attained in
ways other than by introducing such sources of strong allergens into
household of allergic individuals. See Abstract 3-25. In fact, I
have for some time suspected that Cats are the first Aliens to
Earth, and that they are about to take over!
- Several articles offer evidence that premature birth reduces the
of later atopic sensitization. This appears to depend on the fact
that the more immature immune system, when first encountering the
environment, may be more able to develop tolerance to antigens.

NEW AND NOTABLE - 2002: ABSTRACTS OF
RESEARCH IN ALLERGY, IMMUNOLOGY AND BRONCHIAL ASTHMA FROM AROUND THE
The following represent my “take” on the Year 2002 research and
offerings previewed for the March, 2002 annual meeting of the
Academy of Allergy, Asthma and Immunology held in New York
These notes are derived from over 1,100 abstracts recently published in
the Journal of Allergy amd Clinical Immunology, January 2002.
This seems to be a year of building upon previous break-throughs,
a few developments new to me. The disease of the decade continues
to be Bronchial Asthma, still the most underestimated and undertreated
serious disease in America, except perhaps for high blood
This is a real shame, for there is no lack of scientific insights or of
therapeutic modalities for both of these potential killers. There
is still an embarrassing and risky lack of implementation on the part
many physicians, and a devil-may-care attitude on the part of many
The numbers which accompany each personal commentary refer to the
abstract(s). Many if not most of the abstracts will be published
as complete articles during the coming months in the Journal of
and Clinical Immunology.
1) Aspirin / NSAID-Induced Asthma (#50,220):
Contrary to decades - old clinical impressions, aspirin -

Such patients should thus be fully evaluated. Potential reactions
fall into two categories, although not totally separate: urticarial /
reactions; and severe (or suddenly lethal) asthmatic reactions.
desensitization under controlled circumstances is not only possible,
is also useful in achieving better control (through subsequent constant
aspirin dosage) of both asthma and rhino-sinusitis.
2) Heparin (#65,66,430,431):
Heparin is an agent generally used as an
It has several other pharmacologic properties which may find clinical
One of these is its anti-inflamatory property which, when applied by

On the other hand, heparin is highly antigenic. This, in addition
to the well-known side-effect of thrombocytopenia, it may produce
acute allergic reactions. Immediate and delayed-type skin testing
may be useful in evaluating this problem.
3) Diesel Exhaust (#75,468):
It has been known for years that, in addition to being
noxious, diesel fumes contain chemicals which increase the level of IgE
(the allergic antibody) in humans. Such exposure also favors the
development of Th2 - type immune responses. Both actions provide
the conditions necessary to produce allergic reactions and may be an
reason for the epidemic of asthma in the western world during the last
two decades. In fact, the particular preponderance of bronchial
in children of inner cities may well be related to the inordinate
of time school - age children spend on school buses with diesel engines
running, estimated to be about 180 hours per year. Local and
agencies are beginning to address the issue of school bus engine
4) The Hygiene Theory (#80):
This theory is based upon numerous observations

likely valid, a few reports have tended to confound the lessons to be

question is necessarily revisited by researchers and by the FDA.
5) Bronchial Asthma (#86,511,514,792,1099,1100):
Severe bronchial asthma, often steroid-resistant, is the
of many studies. The “Tenor Study”, as established, is positioned
to provide much epidemiologic and longitudinal information, perhaps
to the Framingham Study. The Denver Study describes troublesome
that - despite all the therapeutic modalities in use - loss of lung
and often loss of steroid responsiveness continue, especially in asthma
dating from childhood. In my opinion, this unfortunate situation
is due to at least three factors: a) the lack of compliance by most
- who should know better - with the numerous treatment protocols
established for the proper treatment of bronchial asthma; b) although
developing evidence that prolonged use of inhaled steroids may actually
contribute to “re-modeling” - scarring of lung tissue; c) the tendency
of many people to underestimate the severity of their asthma; d) the
failure of most physicians, pulmonologists and even some timid
to implement the clear theoretical and abundant evidence-based
supporting the use of immunomodulation - in the form of specific
allergy immunotherapy - to eliminate the causes of the asthmatic
process, rather than pursuing its effects. The proper approach to
bronchial asthma is a complete medical and allergy evaluation by a
allergist (since no one else seems able or willing to do it
The proper treatment is comprehensive, including environmental control,
absolute cessation of smoking, expert use of the multiple medications

medication for emergency use in acute asthma.

The above references describe other uses being studied for this class
- Reduction of pain and itching from local reactions to allergy
Rarely, a patient may experience recurrent delayed (12-24 hour)
local reactions which interfere with compliance and with progression of

blood pressure) who has or strongly suspects food and/or medicine
10) Mastocytosis (Ref. #202):
This is a condition characterized by an excess number of
cells in the body (in skin and/or in mast cell tumors), the major
of histamine and other chemicals that can produce allergic reactions or
allergic-looking reactions. It can be an occult cause of
reaction. It can be detected fairly easily with a blood and/or
test, and occasionally with a biopsy.
11) The Allergic Rhinitis...Asthma Connection. (Ref. #239):
Numerous studies have shown that allergic rhinitis (hay
with or without ”sinus trouble”) is often a precursor to the
of bronchial asthma, a sequence which can be avoided by treating the
rhinitis with specific allergy immunotherapy.
12) Allergy to Penicillin (Ref. #251,419,420):
Many more people carry a history of “allergy to penicillin”
than are actually allergic to penicillin. This is not to minimize
in any way the central role of the medical history in making treatment
decisions about the use of penicillin and related antibiotics.
where circumstances warrant a more definitive diagnosis with
effect on the choice among limited antibiotics, skin testing is very
and dependable. It can reduce the use of more high-tech
and thus reduce the development of resistance to these important

tissue changes, of allergic reactions in some patients.

14) Steroid Oral And Nasal Inhalers: (Ref # 282, 543, 734, 770):
Budesonide (Pulmocort) has emerged as a prerferred
Meanwhile, the side effects in children appear to be overestimated,
to the under-use of budesonide and other inhaled steroids. And
potential steroid side-effects in adults (such as osteoporosis and
insufficiency) appear to be underestimated.
15) Chronic Urticaria: The Pain and Bane Of Allergists’
(Ref.# 355, 357, 358, 360, 363, 365):
Prudent use is the message here.
Here is another area where we constantly “practice”
we never get it right!
16) ACE Inhibitors / Angioedema Connection. (Ref.#370, 428)
These articles again point out the frequent association between
“chronic” hives (6 or more months duration) and auto-immune diseases
auto-antibodies (expecially anti-thyroid and ANA antibodies).
associations discussed include insulin (definite) land H. pylori
The prolonged use of sulfadiazine (6 weeks) is also suggested
as a treatment for chronic urticaria of unknown cause. This would
be in line with the fact that “hives” can be the body’s response to
(eg. foods), infections (eg. urinary tract or dental infections,
etc.), or to a malignancy.

(Ref.#412, 413, 416):
This is real, but the greater dangers from
are overuse, leading liver toxicity, and deliberate overdosage - with
fatal consequences if not treated promply.
20) Anti-IgE (Omalizumab) (Ref.#458, 460):
This agent, still in clinical trials, will very likely be
effective addition to our treatment modalities. But, is
another “anti-”drug rather than an effort to reverse the
immunologic mechanism through specific immunotherapy? I think so.
21) Tacrolimus (Protopic) (Ref.#470,471,1089):
This is the newest non-steroidal topical agent for moderate
to severe eczema, and appears to be a real addition to available
If this doesn’t work, the authors suggest a really big gun:

Intravenous gammaglobulin is used as replacement therapy in
immunoglobulin deficiency states. It has also been used in recent
years to treat an increasing number of pathologic conditions of
cause through an ill-defined mechanism generally assumed to be
And it works many times!
23) Latex Allergy (Ref.#785, 873,1033):
The treatment is, however, somewhat laborious to administer; and it
carries a small risk of side effects, including the possibility of
- type reaction. The above reference describes the sub-cutaneous
administration of Ig, avoiding the inconvenience and the
with reportedly better trough levels. This is worth checking out
if you are in that arena.
A little more information.
24) Epinephrine (Ref.#788):
We may soon have a sub-lingual epinephrine for use in acute
allergic reactions, instead of the Epi-pen self injectors. Stay
26) Anti-Histamines and Skin Testing (Ref.#805):
25) Gluten Intolerance (Celiac Syndrome) and Wheat Intolerance
Avoiding gluten in foods is more difficult than might be expected for
patients so afflicted. It is, of course, the entire basis for
treatment and is thus highly important.
Skin testing, (particularly intradermal skin testing,
as the gold standard), is very important, second only to a carefully
medical and allergy history in the diagnosis of allergic, IgE mediated
diseases. The intake of anti-histamines suppresses and may negate
the results, which depend on the release of histamine in the skin
from the antigen-antibody reaction being sought. 1st generation
(Chlortrimeton, Benadryl) should no longer be used, except in an
because of the sedative effects and also because of their reflex
impairing activity (eg. in driving). 2nd generation
generally lack these side effects. But their effect on skin tests
is of much longer duration. This is true of claritin, allegra,
and astelin; and it is especially true of clarinex, the newest arrival
on the scene. Based upon the latest reported evidence,
of these anti-histamines should be taken by a patient scheduled for
testing for one week before the procedure. Of course, the
patient’s symptoms must be otherwise controlled during that
This can ordinarily be accomplished with inhalational or nasal steroid
sprays - or in more complicated cases with a short course of oral
ALLERGIC SYMPTOMS CAN ALWAYS BE CONTROLLED. THE TRICK IS TO DO SO
WITH THE MOST EFFECTIVE COMBINATION OF MEDICATIONS, THE FEWEST SIDE
WITH A COMMITMENT TO TREATING - AND REVERSING - THE UNDERLYING
PROCESS RATHER THAN MERELY TREATING SYMPTOMS. THAT IS THE
ALLERGIST’S STOCK IN TRADE.

A number of abstracts address the use of various medications
in this field. Of note are three issues:
1) The unresolved controversy regarding whether to use

serevent-salmeterol). (#338,339,365) I try to avoid

“Stock bacterial vaccine” is a product used for the last

experience, to be effective in the reduction of “allergic”

bronchitis). The mechanism has been thought to be its endotoxin

Notes Taken from Articles Abstracted in
Allergy, Asthma, and Clinical Immunology 2000
- Many articles address the various functions of different
the pathogenesis of allergies.
- An article on page 17 demonstrates that Staphylococcal toxin, a
super antigen, augments specific IgE responses by atopic patients

- An article on page 68 supports the evidence of discordance
of inflammatory interleukens such as IL4 and IL5 and continued changes
of remodeling in asthma. Once again this increases the importance
of avoiding the entire reaction in the first place with comprehensive
including allergy immunotherapy and environmental control.

ventilation requirement, thus allowing an individual with
bronchospasm to exercise for a longer period before triggering

- An article on page 86 emphasizes that importance of introducing
steroids early in the treatment of childhood asthma in order to avoid
responsiveness later, probably associated with airway remodeling.
- An article on page 90 describes the central role of eosinophils
cationic protein and major basic protein in the development and
of airway inflammation. This appears to be true regardless of
the underlying mechanism is allergic or otherwise.
- An article on page 93 reiterates the central role of RSV virus
respiratory tract infection in early childhood stimulating both
reactions and bronchiolitis. It discusses the value of a safe and
effective RSV vaccine when available. In addition, the article on
page 97 describes treatments other than the usual supportive care which
may be appropriate in patients with serious underlying disorders.
Such treatments might include antiviral therapy, such as Ribavirin and
RSV immunoglobulin. It is generally thought, though not
proven, that patients who have had acute bronchiolitis are much more
to develop asthma subsequently.

of the vocal cords during the respiratory cycle, usually on inspiration
but also possibly on expiration. This can imitate asthma and will
not respond to anti-asthmatic treatment. Once identified, it is
treated with respiratory phonation exercises, and perhaps psychotherapy.

cedar and notes that the reactions to this antigen manifest late or
asthmatic reactions to the plicatic antigen.
- An article on page 129 describes glucocorticoid insensitive

process in the pathophysiology of severe asthma. The paper notes
two distinct pathologic subtypes of severe asthma: (1) the
eosinophilic process with inflammation, (2) the other, eosinophil

type was associated with greater inflammatory cell infiltrate and
incidence of respiratory failure.
- On page 156, we find once again the importance of endotoxin, in
inhaled endotoxin highly concentrated in organic dust. This is a
potent inflammatory agent likely to have a significant role in airway
in patients with asthma. This relates to our premise over many
that the stock bacterial vaccine effectiveness is related at least in
to its endotoxin content.
- On page 161, we find a new name for exercise-induced
“thermally-induced asthma” by E. R. McFadden. He holds that the
of exercise-induced asthma depends largely on the rate of airway
after the cessation of exercise.

some patients with apparently stable asthma who have high bronchodilate
