Are there best practices for integrating pollen, wildfire smoke, and AQI data into asthma/allergic rhinitis action plans?
Living in northern Calif, we frequently incorporate this topic into our patient discussions. We advise virtually all of our asthmatic pts to have a high-quality HEPA air purifier available because they frequently become hard to get when the air quality decreases.
Are you managing chronic urticaria/angioedema any differently if the patient is only/predominantly presenting with urticaria or angioedema?
The mechanism is similar for urticaria and histamine-induced angioedema, so I would expect a similar response. The evidence to support the use of montelukast for U/A is slim, but there are some supporting data. Nonetheless, the newest WAO guideline does not suggest an addition to the therapeutic pyr...
In patients with severe asthma who are candidates for biologics, do you put them on an ICS/LABA/LAMA rather than high dose ICS/LABA?
It depends on the patient and their co-morbidities. For poor compliance, Trelegy can be a game-changer due to ease of administration.
In a young patient who was vaccinated to chickenpox as a child (no previous varicella infection) should the patient receive a shingles vaccine prior to starting Rinvoq?
Yes. The vaccines are different and current vaccine is to prevent zoster for patients who have been previously exposed to varicella or vaccinated for varicella.
Do you withhold performing skin testing for aeroallergens, foods or venoms based on poor lung function?
I do not. However, if a known severe trigger of asthma by history, such as a cat, I instruct staff to wipe off the allergen if a large skin wheal occurs. Additionally, if lung function is compromised, starting the patient on a short course of oral steroids prior to testing will not compromise skin t...
When should we suspect ‘climate-amplified’ rhinitis/asthma versus poor control from other causes?
Before labeling rhinitis or asthma as “climate-amplified,” we must first exclude common causes of poor control: adherence issues, suboptimal controller dosing, inhaler technique, indoor allergen exposure, occupational triggers, and comorbidities (GERD, CRS, OSA, obesity). These remain far more commo...
Should a patient on medium-dose ICS/LABA with normal PFTs, but who shows a greater than 10% decrease in FEV1 if their PFTs are done after 24 hours off their inhaler, be started on a biologic?
A little more clinical information would be useful to better answer the question. How well controlled is the patient on the LABA/ICS? What is the ACT score? The FEV1 decreased by greater than 10% (with volume >200 ml ?) when LABA/ICS was stopped for 24 hours - how quickly did it normalize when the i...
What are your top takeaways from AAAAI 2026?
The presentations related to the treatment of systemic mastocytosis (SM) were the highlight of the AAAAI meeting. They demonstrated that patients with non-advanced SM (NonAdvSM) can achieve complete remission of SM where WHO diagnostic criteria are no longer met. The rate of remission (where WHO dia...
If a patient has chronic spontaneous urticaria refractory to Xolair and is already on plaquenil, do you stop plaquenil and then initiate cyclosporine or do you co-administer and then gradually stop plaquenil over time?
I would first increase the dose of Xolair, actually, up to 600 mg every 2 weeks.
How do you counsel patients with chronic urticaria on the role of stress management strategies in their treatment plan?
There are certain situations or times of the year when increased aeroallergen exposure is expected. It follows that increased vigilance is a management technique for those who suffer with sensitivity to these aeroallergen-induced symptoms in the areas of environmental control, pharmacotherapy, and, ...
