What is your approach for female patients with severe atopic dermatitis well controlled on Dupixent planning to conceive or already pregnant?
Based on published data, I have a few concerns. However, the clinical trials of Dupixent failed to study effects on learning and memory.IL-4 and IL-13 are known to be important for learning and memory in mice. IL-4-producing T cells accumulate in the meningeal spaces, and acute depletion of these ce...
Do you find that hydroxyzine worsens cognitive symptoms in patients who are already susceptible to cognitive impairment?
Hydroxyzine should not have a direct negative effect on cognition. For decades after its inception, it was lopped in with Benadryl in terms of its receptor binding affinity profile and is listed in several anticholinergic burden scales as being anticholinergic. Similar to the child’s game ‘telephone...

Chronic urticaria (6 weeks or longer) is often a self-limited disorder seemingly idiopathic in etiology.

This will help to risk stratify and determine whether same day or future infusions of RTX should be used. Importantly, th...

What to do? Some interesting a...
What type of DES should you opt for if a patient has or is concerned about possible nickel allergy?
For a coronary stent, I would lean toward a Medtronic DES. There are published recommendations for nitinol with a durable polymer. That said, I cannot remember more than one case in 25 years where I thought that a metal allergy may have played a role in a patient receiving a stent and that was prior...
What therapies would be considered safe and effective in pregnant patients with EoE?
Would start with two-diet elimination, milk and wheat can give you close to 50% success. If needed can add esomeprazole, and you should be closer to 70%.
Any thoughts on whether oral immunotherapy versus Xolair would provide a better chance of outgrowing a food allergy?
Because oral immunotherapy is only approved for peanut, the response to this question will be limited to peanut allergy. Any discussion about outgrowing peanut allergy should mention the natural course of peanut allergy. Although some studies suggested that peanut allergy was persistent, subsequent ...
