Therapy for food allergy - Twitter summary from #ACAAI16 meeting

Dr Nadeau presented review of new immunotherapy for treating food allergy. Potential food allergy therapies in this slide: https://t.co/N00tHOvHIh

AR101 - 100% of patients tolerated 443g (2 peanuts) and 78% tolerated the challenge (equivalent to 1g or a peanut butter cookie) https://t.co/3QYxFVtOBO

Possible biologics for peanut allergy in this slide: https://t.co/GkO3TStDge

There is evidence the prevalence of peanut #allergy is not on the rise from comparison of longitudinal cohorts https://t.co/Ds28rZ83Cm

LEAP study: Peanut recommended to be introduced starting around 4-6 months https://t.co/ccs9HulMbz

Guidelines for peanut introduction changing. Introduce early, test if indicated. https://t.co/6MkSc8VE8Q

Peanut allergy guideline coming out Jan 2017 https://t.co/ccOjJbOyvm

However, does LEAP study applies to other foods? Early egg introduction has mixed evidence, trend towards benefit in non-eczema group but towards harm in eczema group. Very mixed picture when it comes to using hydrolyzed formula vs cow's milk formula in eczema. No clear benefit.

What separates Allergists from other specialists: atopy and immunotherapy - Twitter summary from #ACAAI16 meeting


Dr. Hal Nelson presented on What separates Allergists from other specialists?

Allergists are not defined by an organ system. Rather we focus on 'atopy'. Coca and Cooke described Atopy in 1922 - strong hereditary component, clustering of eczema, rhinitis and asthma with positive SPT.

Pollen sensitization a risk factor for allergic rhinitis. Not so for asthma. Perennial allergen sensitization to HDM, animals is important.

House dust mite avoidance can actually reduce bronchial hyperresponsiveness (classic Davos study - moved the kids to HDM free zone) .

Because of differences of impact of seasonal vs perennial allergen sensitization, allergists become armchair Aerobiologists.

Intradermal skin testing is 1000x more sensitive than skin prick testing - is it clinically relevant though? A study showed that with positive intradermal tests (if SPT was negative) were no different than negative tests and lower/upper respiratory symptoms.

Requirements for effective immunotherapy: adequate doses of relevant allergen; attention to cross-reactivity; maintain extract potency.

SCIT effective doses established for ragweed, grass, dust mites, cat, dog, birch and Alternaria mold - of note, dog extract was changed. The RCT that established the effective dose of ragweed allergen to put in an SCIT treatment set was published in 1965!

SLIT is effective and FDA approved SLIT-T, SLIT drops are not FDA approved.

Dr. Michael Nelson presented on Allergen Immunotherapy: Current Best Practices.

Immunotherapy has been around for over 100 year now - a treatment doesn't last that long if it doesn't work.

Starting AIT - should we consider starting earlier to allow for prevention of new sensitizations, new asthma? Knowing that AIT needs to be given for at least 3-5 years to allow for disease modification means selecting the right patient to start.

Best practice is to have a trial off immunotherapy after 5 years - yes, some will recur but many will not, not a reason to do lifelong AIT.

@choirdoc: Biggest surprise in my career was learning how resistant many patients are to stopping IT.

The Payne and Nelson study of AIT prescriptions within DOD database showed only a 50% refill in AIT after 1st year of therapy.

Early and complete patient education leads to enhanced patient selection and adherence - route, procedures, AEs, duration, adherence importance.

The AIT practice parameter published in JACI 2011 shows probable effective doses for both standardized and nonstandardized US extracts.

We need to separate extracts with proteolytic enzyme activities from other extracts. Don't mix molds with pollens - need 2 vials.

Immunotherapy for allergic rhinitis - Twitter summary from #ACAAI16 meeting


Classic lecture by Dr. Nelson on 100 years on immunotherapy #ACAAI16 https://t.co/zQDQWZZGdE

@docalergias: Allergy immunotherapy for AR effectively prevents asthma: https://t.co/yTFQql5VCp

@choirdoc: Wouldn't we be celebrating discovery of a treatment to reduce risk of developing asthma by 40%? Hmm - there is one: immunotherapy. Treating parents with immunotherapy reduces risk of atopy in their future children (dose dependent, too)!

Probiotics might be able to enhance the effectiveness of immunotherapy. Dr. Nelson warns that confirmation is needed. SCIT in combination with probiotics induces regulatory B cells and 30% improvement on symptoms compared to SCIT without probiotics https://t.co/ePShC4Vzq5

@drsilge: Subcutaneous immunotherapy plus probiotics dramatically affected nasal symptoms after 6 months. Fascinating https://t.co/h7ghCsDALB

We can safely administer grass and ragweed sublingual tabs together. Approximately $600/mo wholesale? Cetirizine and fluticasone nasal spray $6.25/mo. Value? @paallergy: That would be $7,200 per year. SCIT is much much cheaper.

Dr Durham: To check for INS spray non-compliance, ask - how many spray bottles did you use during last pollen season? The answers should be 3-4.

There is a need for more research on subtropical and tropical dust mite allergen IT.

Dr Durham explained data from several studies showing efficacy of dust mite SLIT for allergic asthma.

Effectiveness of dust mite SLIT on polisensitized asthmatics: 34% risk reduction in exacerbations - JAMA https://t.co/18h4uoqRRA https://t.co/V0tcGFtr0m

Optimal preseason treatment for SLIT is 4 months.

Possible anti-cytokines targets as adjuvants for SCIT in this slide: https://t.co/86o1BpCCO2

Mycobacterial antigen as potential new adjuvants for SCIT: https://t.co/lXKrhRUKEE

Dr Durham reviewed his well known study of Grass SCIT showing persistent benefit 3 years after discontinuation following 3 yr course.

Grass SLIT-T was also shown to have persistent benefit for 2 years following discontinuation after a 3-year treatment period (given daily year round).

Dr Durham conducted a head to head comparison of Grass SCIT to Grass SLIT-T given over 2 years - funded by Immune Tolerance Network. Durham's SCIT vs SLIT study was placebo controlled - double blind double dummy (i.e. SLIT patients received placebo injections as well). Primary endpoint of the SLIT vs SCIT study was response to nasal allergen challenge at 3 years (2 years treatment, 1 year off treatment). 106 participants randomized - 34 SLIT-T, 36 placebo, 36 SCIT, mean skin test diameter to grass was 8 to 10 mm.

After 2 years of treatment, both SCIT and SLIT showed a significant reduction in response to nasal allergen challenge compared to placebo. After only 1 year of treatment, only SCIT was better than placebo, and in fact, was better than SLIT-T. After 2 years of treatment and 1 year of follow up - neither SCIT nor SLIT were better than placebo. Thus 2 yrs IT was not enough.

There were significant improvement in rhinitis specific QOL during grass in both SCIT and SLIT treated patients even after 1 yr treatment.

@mrathkopf: Durham, GRASS trial - 2 years of treatment is insufficient for long term tolerance for both SCIT and SLIT.

Side effect profile was different - 47% rate of mild systemic reactions in SCIT compared to 2.8% in SLIT. 2 Cases of Grade 3 SR in SCIT.

Dyspepsia occurred in 22% of SLIT treated patients - mild to moderate, no one discontinued secondary to this.

Both SLIT and SCIT reduced nasal IL-4 and IL-13 following nasal allergen challenge after 2 years of treatment. Substantial reduction in grass-specific Th2 cells shown in the SCIT-treated patients c/w placebo. SLIT reduced them as well but less so. Both SCIT and SLIT reduced late phase skin response to intradermal grass test. Grass specific IgG4 increased with both SCIT and SLIT. Both effects were more pronounced with SCIT.

Dr Durham - SCIT and SLIT are in equipoise Both are effective, SLIT is safer - ask the patient which they would prefer. Dr Durham suggests getting patient input for choice of SLIT or SCIT.

SCIT and SLIT are equally effective for seasonal outcomes but we need to treat for 3 years.

@drsilge: 2 years of SCIT OR SLIT are insufficient for lasting benefit. Dr Durham is really the only source for good data on duration.

@dranneellis: The best part of #ACAAI16 so far-spending time with immunotherapy & nasal allergen challenge guru Dr Stephen Durham! https://t.co/xBpzqHeCUH

Resident education program during the 2017 meeting of Florida Allergy, Asthma & Immunology Society (FAAIS)

The Florida Allergy, Asthma & Immunology Society is proud to announce its 2017 Annual Meeting, held at JW Marriott, Orlando, Florida. The three-day meeting will host practicing allergists from Florida.

Dates: June 30 - July 2, 2017

Location: JW Marriott, 4040 Central Florida Parkway, Orlando, FL 32837



More info: http://www.faais.org/events.php

The resident education program is full with great topics which will be presented by world class speakers. Below is the official email announcement from FAAIS:

---

Dear FAAIS Members:

The executive board of the FAAIS is pleased to announce the return of our forum for medical residents in training, which will be held this year in lieu of our allied health program. This one day conference coincides with our annual meeting and offers those attending an extensive review of relevant topics in allergy and clinical immunology. For many, this represents the only time in their training to attend a world class forum in their backyard.

Starting with a review of allergy and immunology the resident will be able to better comprehend the concepts presented throughout the conference. The forum will cover the evaluation and management of patients with IgE mediated disorders, anaphylaxis, urticaria, hereditary angioedema, asthma, advances in targeted therapy and much more.

An important part of this educational initiative is dedicated to creating awareness of the vital role allergists play as consultants. In this regard our hope is to elevate the visibility of our field while promoting the expertise of the Florida Allergy Asthma and Immunology Society.

This promises to be a memorable event!

Sincerely:

Thomas Lupoli, DO
FAAIS President

Nina Ramirez, MD
Resident Program Director
