If you have chronic hives and antihistamines aren't helping, there's a new treatment option to know about. In this episode of The Itch Review, we spotlight "Remibrutinib in Chronic Spontaneous Urticaria" published in The New England Journal of Medicine, March 2025.

This article looks at the REMIX trials, which tested whether remibrutinib, a BTK inhibitor, can help adults whose chronic spontaneous urticaria (CSU) is not controlled by antihistamines alone. Remibrutinib works differently from antihistamines. Instead of blocking histamine after it's released, it stops mast cells from releasing those itch-causing chemicals in the first place.

The FDA approved remibrutinib in September 2025.

Chronic rhinosinusitis with nasal polyps, or CRSwNP, is a condition driven by ongoing inflammation. That is why treatment is not a one-time fix and why polyps can come back even after surgery. In this episode, Dr. Payel Gupta and Kortney are joined by Dr. Maeve O'Connor, a board-certified allergist and immunologist, to walk through CRSwNP treatment options.

This episode is released around World Anosmia Day because loss of smell is one of the most frustrating and most common symptoms of CRSwNP, and one that treatment can actually help with.

Dr. Maeve O'Connor, MD, FACAAI, FAAAAI, is a board-certified allergist and immunologist and founder of Allergy Asthma & Immunology Relief (AAIR) of Charlotte, North Carolina. She treats patients of all ages, practices integrative medicine, and has been named a Top Doctor by Charlotte Magazine since 2007.

We spend about 90% of our time indoors. But what's actually in that air we breathe, and why does it matter so much for people with asthma, allergies, and eczema?

This is part two of our series about indoor air quality. We discuss how you can improve your indoor air quality. Kortney shares her experience living in Germany, where ventilating your home isn't just a suggestion, it's practically a lifestyle. We also go room by room with practical tips you can actually use, from washing your sheets in hot water to why that scented candle might need to go.

Part one covered what causes bad indoor air quality and what causes health problems for people with asthma and allergic diseases.

This series is part of the EXHALE project, a set of six evidence-based strategies designed to help people with asthma achieve better health and improved quality of life. This series supports the last "E" in EXHALE by reducing asthma triggers in indoor environments.

We spend about 90% of our time indoors. But what's actually in that air we breathe, and why does it matter so much for people with asthma, allergies, and eczema?

This is a two-part series about indoor air quality.

In the first part, we break down the three main categories of indoor air pollutants: particulate matter (PM2.5 and PM10), volatile organic compounds (VOCs), and biological allergens like dust mites and mold. Dr. G explains how each one affects the body differently and why people with allergic disease are especially vulnerable.

We continue our tradition of interviewing the incoming president of the American College of Allergy, Asthma & Immunology to learn what is top of mind for the field and what it means for patients and families.

Dr. Cherie Zachary joins us to share her personal journey into allergy and immunology as both a lifelong patient and clinician. She explains what the ACAAI does and why increasing representation in medicine is critical for improving allergy outcomes. The conversation also tackles the allergist shortage, how physicians are trained, and what is being done to expand fellowship opportunities and improve access to care.

What the ACAAI actually does for allergy care: How the College supports clinicians and provides patients with trusted, evidence-based education.

How lived experience shapes leadership: How Dr. Zachary’s own allergic diseases influenced her path into allergy and immunology.

Why representation matters for allergy outcomes: How culturally responsive care and physician diversity improve trust and health outcomes.

Why there are not enough allergists: How training bottlenecks contribute to long wait times and limited access to care.

Historically Black Colleges and Universities (HBCUs): Her focus on expanding exposure to allergy through HBCUs and the ACAAI SPARK program.

We thank the American College of Allergy, Asthma, and Immunology for their support of Allergy & Asthma Network and this podcast. 

Allergy & Asthma Network has spent more than four decades helping people living with asthma, allergies, and related immune conditions navigate care, access trustworthy education, and make their voices heard.

In this episode, we talk with Lynda Mitchell, CEO of Allergy & Asthma Network. Lynda shares how becoming a food allergy and asthma mom in the early 1990s shaped her career and led her into patient advocacy work. We get into how Allergy & Asthma Network supports patients and families through four mission pillars: education, outreach, advocacy, and research.

Asthma is one of the most common long-term conditions in children. It is a leading cause of missed school and emergency room visits. Doctors use tools (validated questionnaires) to assess how well a child’s asthma is controlled and whether their medicine is helping. Some tools only ask about symptoms, which can miss children who are still at risk for asthma attacks.

The lead author, Dr. Kevin Murphy, joins us to talk about “Pediatric Asthma Impairment and Risk Questionnaire: A Control Assessment for Children Aged 5 to 11 Years,” published July 2025 in Journal of Allergy and Clinical Immunology: In Practice.

The Peds-AIRQ was designed to improve how doctors identify uncontrolled asthma in children by asking about both current symptoms and past asthma attacks. This approach helps avoid missing children who may seem okay day to day but are at higher risk for future flare-ups.

Sleep plays a critical role in managing allergies, asthma, and eczema, yet it is often overlooked in conversations about allergic disease.

Sleep affects mood, focus, immune function, and inflammation, all of which influence how allergic conditions show up day to day. Poor sleep can worsen asthma symptoms, increase allergy flares, and make eczema harder to control. At the same time, allergies and asthma can disrupt sleep, creating a cycle that is difficult to break.

Dr. Carol Yuan-Duclair, a sleep specialist, joins us to explore how sleep impacts allergic conditions and overall health. She breaks down what good sleep actually looks like, how to know if you are getting enough rest, and how sleep quality can directly affect allergies, asthma, and eczema.

This conversation focuses on practical guidance for patients and families, including environmental changes, medication considerations, and when it may be time to seek help from a sleep specialist.

Why sleep is essential for health and immune function: How sleep affects inflammation, mood, and overall health, and why poor sleep can worsen allergic disease.

What good quality sleep actually looks like: The difference between sleep quality and sleep quantity, and how to tell if your sleep is truly restorative.

The two-way relationship between sleep and allergies: How allergies can disrupt sleep, and how poor sleep can worsen allergy symptoms, creating a difficult cycle.

Practical ways to improve sleep when you have allergies: Sleep hygiene basics, exercise timing, and creating a healthier bedroom environment.

When medications or symptoms mean it is time to see a specialist: How allergy medications can affect sleep, how eczema fits into the picture, and when ongoing sleep issues may signal the need for a sleep specialist.

Reading food labels can feel like a full-time job when you or your child has food allergies. Even when you know what to avoid, labels can still be confusing, especially when you run into “may contain” warnings.

Marion Groetch, a registered dietitian with decades of experience in food allergy care and education, joins us to unpack all things food labels. Together, we break down U.S. allergen labeling laws, what parts of the package actually matter, and why “may contain” statements are a much grayer area than most people realize. We also share practical tips for navigating so-called “mystery ingredients” like natural flavors and oils, when it is worth contacting a manufacturer, and how to avoid being more restrictive than necessary while still staying safe.

Clonal mast cell disease is often missed because symptoms vary from person to person, tryptase levels can be normal, and bone marrow biopsies are hard to get. For some people, unexplained or very severe anaphylaxis may be an early sign of a clonal mast cell disease.

In this episode, we review “Prevalence of KIT D816V in anaphylaxis or systemic mast cell activation,” published in October 2025 in the Journal of Allergy and Clinical Immunology. This paper, known as the PROSPECTOR trial, is looking at how often the KIT D816V mutation can be found using a blood test in adults who have had anaphylaxis or systemic mast cell activation symptoms.

We break down why KIT D816V matters, how it connects to systemic mastocytosis, why HaT needs to be considered, and how newer blood tests may help doctors catch clonal mast cell disease earlier.
