In this episode, we’re concluding our review of the Global Initiative for Asthma (GINA) guidelines on asthma today with a cased based episode on special considerations in asthma care. We’ve covered asthma diagnosis and phenotyping, the approach to therapy inhaler and oral medical therapy, and biologic therapy. On today’s episode we’re talking about complex cases that are at the edges of the guidelines, or may be in future guidelines. To help us with this exciting topic we’re joined by an expert in the field. Enjoy!
Meet Our Guest
Dr. Meredith McCormack is a Professor of Medicine at Johns Hopkins, where she leads multiple NIH funded endeavors at understanding lung health and disease. She is the Division Director for Pulmonary and Critical Care Medicine, while also directing the Asthma Precision Medicine Center of Excellence, and the BREATHE Center, which focuses on understanding the effects of the environment on lung health and disease through research and community engagement. She is an internationally recognized expert in asthma management and is a dedicated member of the faculty who is committed to the trainees.
Meet Our Co-Hosts
Rupali Sood grew up in Las Vegas, Nevada and made her way over to Baltimore for medical school at Johns Hopkins. She then completed her internal medicine residency training at Massachusetts General Hospital before returning back to Johns Hopkins, where she is currently a second year pulmonary and critical care medicine fellow alongside Tom. Rupali’s interests include interstitial lung disease, particularly as related to oncologic drugs. And she also loves bedside medical education.
Tom Di Vitantonio is originally from New Jersey and attended medical school at Rutgers, New Jersey Medical School in Newark. He then completed his internal medicine residency at Weill Cornell, where he also served as a chief resident. He currently is a second year pulmonary and critical care medicine fellow at Johns Hopkins, and he’s passionate about caring for critically ill patients, how we approach the management of pulmonary embolism, and also about medical education of trainees to help them be more confident and patient centered in the care they have going forward.
Key Learning Points
Episode themes
Biologics: switching vs dual therapy
- Upstream: anti-TSLP (e.g., tezepelumab) may help when multiple pathways/biomarkers (e.g., high IgE + eos) suggest broader blockade.Downstream: IL-5/IL-4/13/IgE agents selected to match phenotype/endotypes.
- Nasal polyps or upper airway syndromes: there are biologic options that improve upper airway symptoms in addition to asthmaAtopic dermatitis: agents with dual indications can be life-changing.
- Remove non-essential add-ons first (e.g., antihistamines, leukotriene modifiers).Reduce ICS dose gradually (high → medium → low).Keep ICS/LABA combination among the last therapies to taper
When patients don’t respond to biologics
- Adherence/technique for inhalers and biologic.Biomarkers behaving as expected (e.g., eosinophils falling on anti-IL-5).Revisit the diagnosis and contributors/mimics (e.g., vocal cord dysfunction, upper-airway disease).
- Consider moving upstream (e.g., to TSLP) if a downstream agent underperforms.
Communication & practical pearls
- Use visual aids to verify what patients actually take and how (e.g., Asthma & Allergy Network inhaler pictogram).
- Needle issues are common; home vs clinic administration and family support can make or break adherence.
- Biologics are transformative for the right patient—consider them early in steroid-dependent or poorly controlled severe asthma.
- Think longitudinally: plan for monitoring, comorbidity management, and timely adjustments.
