    #136 - Food Allergy Treatments: What to Ask Your Doctor

    Avoidance has long been the standard for managing food allergies. But new options, such as oral immunotherapy (OIT) and biologic medications like Xolair (omalizumab), are changing the landscape. With more choices available, many patients and parents are wondering how to start the conversation with their allergist and what questions to ask. Kortney and Dr. Payel Gupta talk with Dr. Shahzad Mustafa, a board-certified allergist and immunologist, about how patients can navigate today’s food allergy treatments with confidence. Together, they explore what to consider before starting OIT or Xolair, how to set realistic expectations, and why strict avoidance is still the right choice for many families. What we cover about food allergy treatment options: Food Allergy Avoidance: Why it remains an effective and valid approach for many, and how to make it work in daily life, including the nuances that make every case unique. Oral Immunotherapy (OIT): What it involves, who it’s best suited for, and what families should know about time, cost, and safety. Xolair (omalizumab): How this injection therapy works to reduce reactions from accidental exposures and what it doesn’t do. Setting expectations: How to talk with your allergist about your goals, quality of life, and what “success” really looks like.

    #135 - Food Allergies in School: A School Nurse’s Perspective

    When it comes to keeping kids with food allergies safe at school, school nurses are often the quiet heroes behind the scenes. From managing allergy action plans and emergency responses to training teachers and organizing care for hundreds of students, their role is essential, but often misunderstood. Kortney and Dr. Payel Gupta sit down with Elizabeth Elliott, a school nurse and President of the Maryland Association of School Health Nurses. Liz shares what really happens inside the health room and how school nurses coordinate care for students with food allergies and asthma. Plus, why communication between families and school staff is key to keeping kids safe. After this episode, you’ll have a whole new appreciation for your school nurse and a better understanding of how to partner with them to make every school day safer for kids with allergies. What we cover about food allergy management at school: The school nurse’s role: How nurses bridge communication between families, teachers, and doctors to keep children with food allergies safe and included during the school day. Coordinating care: How school nurses use action plans and 504s to ensure everyone, from teachers to cafeteria staff, knows how to keep kids safe. Training and emergency preparedness: How school nurses teach staff to recognize anaphylaxis, use epinephrine, and stay calm during an emergency. Field trips, cafeterias, and bus safety: What goes into planning safe experiences beyond the classroom, and why “no-food on the bus” rules really matter.

    #134 - How Dupilumab Reduces Mucus Burden in Asthma - VESTIGE Trial

    Mucus plugging is a challenge in asthma care. It’s thick, sticky mucus that blocks the airways and doesn’t respond to regular inhalers. Even when inflammation improves, these plugs can lower lung function, limit how well medicine works, and make asthma harder to control. In this episode, we break down the study: “Effect of Dupilumab on Mucus Burden in Patients with Moderate-to-Severe Asthma,” published October 28, 2025. The analysis looks at whether dupilumab (Dupixent), a biologic that blocks IL-4 and IL-13, can lower mucus burden and improve lung function, especially in people who start with a high “mucus plug score.” What we cover in our episode about dupilumab and mucus plugging Why mucus plugging matters in asthma: Discover how thick, sticky mucus can block airways, make it harder to breathe, and why standard inhalers and steroids don’t clear these plugs. How dupilumab may help: Learn how this biologic blocks IL-4 and IL-13, two key drivers of type 2 inflammation that increase mucus production and thickness. Inside the VESTIGE study: Hear how researchers measured mucus burden using CT scans and “mucus plug scores” to see if dupilumab could reduce plugging in moderate-to-severe asthma. What the results showed: Find out how dupilumab lowered mucus plug scores, reduced airway inflammation, and improved lung function (FEV₁), especially in people with high mucus burden. What this means for patients: Learn why identifying and treating mucus plugging may help improve breathing, reduce flare-ups, and make asthma easier to manage day to day. 📌INFOGRAPHIC to follow along  RESOURCES: What is asthma?

    #133 - What is Chronic Rhinosinusitis with Nasal Polyps (CRSwNP)?

    Living with constant congestion, facial pressure, or a loss of smell can make daily life exhausting. For many people, these symptoms are more than just allergies or a lingering cold. They may be signs of chronic rhinosinusitis with nasal polyps (CRSwNP). Dr. Rohit Katial joins Kortney and Dr. G to unpack what CRSwNP really is, how it develops, and why type 2 inflammation plays such a key role. Together, they explain what’s happening inside the sinuses, what symptoms to look for, and when it’s time to see a specialist. What we cover about CRSwNP: What CRSwNP means: Chronic rhinosinusitis with nasal polyps is long-term inflammation of the nose and sinuses that lasts 12 weeks or more. What nasal polyps are: Soft, fluid-filled sacs (often “grape” or “pea” sized) that block airflow and lead to congestion and smell loss. Why it happens: Type 2 inflammation drives CRSwNP. Immune messengers like IL-4, IL-5, and IL-13 cause swelling and fluid buildup in the nasal lining. Who it affects: CRSwNP often overlaps with asthma, allergies, or aspirin sensitivity (AERD or Samter’s Triad), making symptoms worse. When to seek help: If congestion, pressure, or loss of smell lasts more than 12 weeks, see an allergist or an ENT specialist. Early care can prevent sinus damage and improve breathing and quality of life. More episodes to support CRSwNP Ep. 101: What is Type 2 Inflammation?

    #132 - Boundaries & Communication in Food Allergy Families

    Navigating food allergies is tough enough, but adding family dynamics to the mix can make things even more complicated. When loved ones don’t understand you or your child’s allergies or dismiss the rules meant to keep them safe, it can lead to conflict, hurt feelings, and stress for everyone involved. Kortney and Dr. Payel Gupta sit down with psychologist Dr. Amanda Whitehouse to talk about how families can find common ground when emotions run high. Together, they unpack what it means to stay regulated in difficult conversations, how to set healthy boundaries with family members, and why understanding different coping styles can help prevent conflict before it starts. What we cover about communication and boundary-setting for food allergy families: Coping styles and conflict: Learn how different stress responses, such as “fight” versus “flight,” shape how partners, parents, and relatives react to food allergy challenges. Staying calm and regulated: Understand how your body reacts to stress and how recognizing those signals can help you stay grounded during tough conversations. Setting and holding boundaries: Get practical tips for explaining what feels safe, keeping communication clear, and responding calmly when others push back. Working together as a team: Whether it’s with your partner, kids, or extended family, learn how to support each other and stay united when emotions rise. Bridging family differences: Explore ways to include children and siblings in allergy safety, and approach older relatives with patience and compassion when views or communication styles differ. ___ Made in partnership with The Allergy & Asthma Network.

    #131 - What Is a BTK Inhibitor?

    For decades, allergists have focused on blocking what happens outside the mast cell: histamine, IgE, and interleukins. But now, there’s a new way to stop allergic inflammation before it even starts: by targeting what happens inside the cell with BTK Inhibitors. Dr. Payel Gupta and Kortney are joined by Dr. Matthew Giannetti to unpack what BTK actually does and why inhibiting it represents an exciting breakthrough in allergy and immunology. Together, they explore how BTK inhibitors work, why this inside-the-cell approach is different from anything before, and what it could mean for people living with chronic spontaneous urticaria (CSU). What the episode covers about BTK inhibitors: BTK explained: Bruton’s tyrosine kinase is a pivotal “last step” before mast-cell degranulation. How BTK inhibitors work: Blocking BTK can stop histamine release downstream of many outside triggers. The science: Why BTK binding is irreversible for each molecule and how the body “re-makes” BTK over time. Safety in brief: A look at petechiae (small pinpoint spots), what to monitor, and how shared decision-making guides treatment choices. The future of BTK inhibitors: Exploring their potential role in other allergic conditions.    ____ Made in partnership with The Allergy & Asthma Network.

    # 130 - How Telemedicine Improves Access to Care for Food Allergies

    Seeing your allergist on a screen instead of in the office might feel strange at first, but for many people with allergies, telehealth isn’t just convenient.  it’s effective. In this episode, we sit down with telemedicine pioneer Dr. Jay Portnoy to explore how virtual allergy care works, what it can and can’t do, and how it’s helping patients get the care they need without the wait or the long drive. Dr. Portnoy shares over two decades of experience leading allergy telemedicine programs in rural areas and explains how remote care has grown from a fringe idea into a standard part of allergy care. He and Dr. G also discuss the benefits for both patients and clinicians. So how do you know when telehealth is enough and when it’s not? What we cover in our episode about virtual allergy care and telemedicine: How does telemedicine work for allergy patients? Learn how video visits and asynchronous tools are making care faster and easier, especially in rural or underserved areas. Telemendine limitations. We break down when in-person care is still needed, like for food challenges, skin tests, or urgent symptoms. Privacy and safety in virtual care. From HIPAA-compliant platforms to quiet spaces at home or in schools, we talk about how to keep your virtual visit just as private as a clinic one. How testing works with telemedicine. Telehealth doesn’t mean skipping tests. Many can be ordered remotely and done at a local lab or clinic near you. The future of allergy care. Hear how virtual care is shifting toward patient choice, whether you want to video call, send a message, or still come in. ___ Made in partnership with The Allergy & Asthma Network.

    #129 - Omalizumab for Multiple Food Allergies – The OUtMATCH Trial

    Multiple food allergies are a daily stressor for millions of families. From avoiding social events to fearing accidental exposures, it can feel like living in a constant state of alert. Until recently, there were no FDA-approved treatments that targeted more than one allergen at a time. In this episode, we break down the study: “Omalizumab for the Treatment of Multiple Food Allergies,” published in 2024 in the New England Journal of Medicine. Known as the OUtMATCH trial, it’s the first large-scale study to show that omalizumab (Xolair), a biologic already used for asthma and hives, may help people with multiple food allergies by raising the threshold for reactions. We explain how omalizumab works by blocking IgE, the antibody that triggers allergic reactions, and how the study measured changes in reaction thresholds (the amount of an allergen a person can ingest before reacting). We also explore the trial design, results, safety profile, and what all of this means for the day-to-day management of food allergies. What we cover in our episode about OUtMATCH trial How omalizumab works to prevent allergic reactions: Learn how blocking IgE increases the amount of allergen needed to trigger symptoms, offering protection from small, accidental exposures. Who qualified for the OUtMATCH trial and why: Find out which patients were included and how eligibility impacted outcomes. What success looked like in this study: Understand how researchers defined protection across multiple allergens. Why not everyone responded the same to omalizumab: Explore the variability in results and what it means for clinical care. What else the study found beyond food challenges: Hear about safety findings, quality of life data, and the open-label extension. 📌 INFOGRAPHIC to follow along  The Itch Review, hosted by Dr. Gupta, Kortney, and Dr. Blaiss, explores allergy and immunology studies, breaking down complex research in conversations accessible to clinicians, patients, and caregivers.
