Would rhapsido be beneficial in patients with MCAS who experience anaphylaxis?
Remibrutinib is the first FDA-approved BTK inhibitor (BTKi). The efficacy data shared were specifically in patients with CSU who failed 4x antihistamine therapy. This class of medication holds promise and may be applicable to other conditions we treat, including anaphylaxis. I refer you to an intere...
How often do you rely on using the C1 inhibitor functional assay versus the quantitative level alone to diagnose HAE?
We have seen a significant increase in lab costs billed to well-insured patients for some of the more "esoteric", detailed testing associated with immune/inflammatory disorders such as HAE. The cheapest screen is a C4 level, which, if normal during an active angioedema episode, makes C1 inhibitor de...
Do you prescribe silvadene cream for patients with a sulfa allergy?
No. I will consider hydrogel wound dressings in those situations
Should thunderstorm asthma be incorporated into asthma action plans?
Thank you for the ongoing dialogue around thunderstorm-associated respiratory events. These episodes represent not just allergen exposure but a combined aeroallergen–irritant phenomenon involving pollen fragmentation, fungal spore surges, PM2.5 downdrafts, ozone shifts, and the priming effects of pr...
In which patients with CHE will you prioritize early use of delgocitinib?
I can't think of any that I'd prioritize specifically compared to other patients. Trial of high-potency topical steroids, then Anzupgo next visit if not doing great. Other key point is to stop the steroid when you start the Anzupgo - topical steroids have a very strong negative impact on barrier fun...
How do you approach performing a food challenge in a patient with CSU who is dependent on their H1 blockers?
We will perform food challenges for patients with CSU using 2 approaches depending on the patient and clinical history. Stop H1 blocker and start prednisone at the same time, continue until the day of the oral challenge, use that as a bridge to block the hives, do the challenge, then resume H1 block...
How do you counsel patients with HAE to best ensure timely administration of on-demand treatments for attacks?
Use at the first symptoms or signs of an attack. The earlier the better.
How are you addressing accurate dissemination of information to patients with the increase in inaccurate information in the digital era?
There are some patients who have already “fallen down the rabbit hole” and are unlikely to be convinced of anything other than the inaccurate information. With these patients, I try to use diplomatic speech such as “we don’t have good evidence/data for this,” “that would be pretty atypical,” or “it ...
Is there a role for phenotyping patients with CSU outside of a research setting by ordering IgG-anti-TPO, IgG-anti-FceRI , total IgE, total IgA etc.?
I do think it can be helpful in patients who have difficult-to-control disease. Many of these (e.g. IgG-anti-TPO, total IgE, anti-thyroglobulin antibody) have been shown to help predict responsiveness to omalizumab treatment or have been associated with disease activity (Højgaard Pedersen et al., PM...
How do you address the discrepancy between traditional allergy skin testing and the Rinkel skin test results?
No one asks about the Rinkel skin test.
