The Itch: Allergies, Asthma, Eczema & Immunology

Did you know you could potentially reduce your baby’s risk of developing food allergies by up to 80%?

That’s the power of early allergen introduction. Feeding a baby the top 9 allergens consistently starting between 4 to 6 months can make a life-changing difference.

We’re launching a brand-new series about food allergies at various stages of life. Whether you’re just starting solids, navigating a new diagnosis, or in a new stage of life, this series is here to support you with evidence-based tips and real talk. In this first episode, Kortney and Dr. Payel Gupta explore how to potentially prevent food allergies before they even develop.

Why do you want to know more about introducing allergens to baby?

For years, parents were told to wait until toddlers were older before introducing allergenic foods. But groundbreaking research, including the LEAP, LEAP-On, and PETIT studies, turned that advice on its head.

We no longer wait to feed babies food allergens. Instead, early (around 4–6 months) and sustained exposure to top allergens like peanut and egg is recommended for all babies. In this episode, Dr. G and Kortney explain the studies, walk you through how to do it safely, and bust common myths that leave parents confused or anxious.

What we cover in our episode about early allergen introduction

• Why guidelines changed: Learn how the LEAP & PETIT studies reshaped allergy prevention.
• How to introduce the top 9 allergenic foods safely, including forms that are appropriate for infants.
• What “sustained exposure” means and how often to serve allergens after that first taste.
  How eczema increases allergy risk and what transcutaneous sensitization means.
• What allergic signs to watch for: mild hives vs. serious allergic reactions and when to call the doctor.

Have you wondered why having more drug options matters for chronic rhinosinusitis with nasal polyps?

In the inaugural episode of our new series, The Itch Review, co-hosts Kortney and Dr. Payel Gupta, along with special guest Dr. Michael Blaiss, unpack the journal article "Tezepelumab in Adults with Severe Chronic Rhinosinusitis with Nasal Polyps," published in the New England Journal of Medicine on March 1, 2025.

This article is about the Phase III WAYPOINT trial of tezepelumab. Already approved for severe asthma, this once-monthly biologic is now showing promise in chronic rhinosinusitis with nasal polyps (CRSwNP). Over 52 weeks, 408 patients were randomized to receive 210 mg of tezepelumab every four weeks or placebo. Researchers tracked nasal-polyp scores, congestion, sense of smell, and rates of rescue surgery.

In this episode, we provide a brief overview of what CRSwNP is, why inflammation drives polyp formation and how blocking TSLP fits into today’s biologics options. We’ll walk you through the WAYPOINT Phase III design, explain the primary and secondary endpoints, and translate the headline results into what they mean for real-world patients who’ve exhausted their treatment options.

Ever wonder if the “asthma shot” from the ER, or those go-to steroid pills for your asthma flares, might be doing more harm than good?

Dr. Dipa Sheth joins us to discuss the common pitfalls of relying too heavily on oral corticosteroids (OCS), also known as oral steroids. We unpack why these systemic medications should generally be reserved for short-term use. She also shares how improving asthma control can help you avoid frequent steroid use in the first place.

Although oral steroids can effectively treat asthma flare-ups in emergency settings, overuse poses significant risks, from adrenal insufficiency to osteoporosis. We dig into ways patients can proactively manage their asthma, reduce ER visits, and talk to healthcare providers about preventive treatments (like inhalers or biologics for asthma) that keep inflammation in check without the side effects of frequent steroid use.

Note: Although we discuss oral corticoid steroids, they can also be given as injections or via IV drip for asthma. We would also like to refer to them as systemic steroids as they impact the entire body, unlike inhaled steroids, which target the airways and lungs. 

What we cover in our episode about oral steroid overuse

• Understanding Oral Corticosteroids (OCS): Learn what these steroids (often called the “asthma shot” in the ER) are and how they can help with severe flare-ups.
• Why Overusing Steroids Can Be Risky: Discover the potential long-term side effects of relying on systemic steroids (pills, injections, or IV), from adrenal insufficiency and osteoporosis to more frequent infections.
• Short-Term Fix vs. Lasting Relief for Asthma Care: Learn how urgent care or ER visits may mask an under-managed condition and why seeing a specialist can improve asthma control.
• Safer Alternatives to OCS: Explore inhaled corticosteroids, biologics, and other preventive treatments that target asthma at its source, reducing the need for frequent steroids.
• Taking Control and Reducing ER Visits: Get practical strategies for working with your healthcare provider to minimize steroid use, prevent flare-ups, and break free from the cycle of repeated steroid courses.
