    #181 - The INTEGUMENT-OLE Trial: Roflumilast Cream for Kids Ages 2 to 5

    Many parents worry about using eczema creams on young kids for a long time. In this episode of The Itch Review, we look at a study of roflumilast cream.  Kortney and Dr. Payel Gupta are joined by allergist Dr. Michael Blaiss to review "Long-Term Safety and Efficacy of Once-Daily and Proactive Twice-Weekly Roflumilast Cream 0.05% for Mild-to-Moderate Atopic Dermatitis in Children Aged 2-5 Years From a 52-Week, Phase 3 Trial (INTEGUMENT-OLE)," published in Pediatric Dermatology, March 2026.  The FDA approved roflumilast cream 0.05% (Zoryve) for mild to moderate atopic dermatitis in kids ages 2 to 5 in October 2025. What we cover in this episode about eczema treatment for young kids The study design and what OLE means.  Why parents stop eczema creams early. Warnings on eczema creams can scare families. Many stop treatment too soon, even when their doctor says to keep going. How roflumilast works. Dr. Blaiss explains it as easing off the gas pedal for inflammation. Young kids use a lower strength because their skin soaks up more. Safety over a year. Only 2.5% of kids had cream-related side effects. Stinging or burning happened in less than 1% of kids.  Secondary endpoint. Kids whose skin cleared moved to twice-weekly use. Half of them stayed clear for close to 8 months or longer.

    #180: What Is Eczema (Atopic Dermatitis)?

    Atopic dermatitis is the most common type of eczema. It is not just dry skin. A weak skin barrier and an overactive immune system work together to cause dry, itchy, inflamed skin. Kortney and Dr. Payel Gupta are joined by Dr. Ted Lain, a board-certified dermatologist and host of the Science of Skin podcast. We go back to the basics: what atopic dermatitis is, why it itches so much, what it looks like, and what really sets off a flare. What we cover in this episode about atopic dermatitis Eczema vs. atopic dermatitis. Eczema is an umbrella word for itchy, scaly rashes. Atopic dermatitis is the most common type. Either word is fine at the doctor's office. What is happening in the body to cause atopic dermatitis. Dr. Lain explains the skin barrier as water balloons held together by mortar. In atopic dermatitis, water gets out, and things like dust, pollen, and germs get in. Is eczema just dry skin? The immune system overreacts like “a train without brakes.” That is why moisturizer alone is not enough, and why newer treatments target the immune system. The itch, scratching, and sleep. Scratching hurts the skin even more, but “just don't scratch” is not real advice. Itch often feels worse at night, when there is less to distract you. Flares, triggers, and food. Fragrances, harsh products, scrubbing, and rough fabrics can trigger flares. Food rarely causes eczema, so strict diets and online food tests usually do more harm than good. ************ Made in partnership with The Allergy & Asthma Network.

    #179 - What Pharmacists Around the World Recommend for Allergies

    The pharmacist is often the first person you talk to about allergies. So what are they thinking about when they hand you that box of antihistamines? Dr. Gupta and pharmacist Dr. Suzanne Soliman went to the World Congress of Pharmacy in Montreal. They asked pharmacists from the UK, Ghana, Portugal, Argentina, Uruguay, and Malaysia about three patients they might meet at the counter. Kortney joins Dr. G to talk through what the pharmacists shared: check that it’s really allergies, skip the older antihistamines, and look at the whole person. What we cover in this episode about pharmacist recommendations for allergy medicine Allergies or a cold? Pharmacists ask three questions: Is there a fever? Is it itchy? Does it keep coming back? Itch and symptoms that return every season point to allergies. When to see a doctor. A fever, pain on one side of your face, or coughing and wheezing can mean an infection. You may need a medicine the pharmacist can't give you. Old vs. new antihistamines. Older antihistamines can make you sleepy and slow your reaction time. Pharmacists around the world now choose the newer, non-drowsy ones, like fexofenadine and loratadine. Anticholinergic side effects. Older antihistamines can also cause dry mouth, constipation, trouble peeing, blurry vision, and confusion. These side effects hit older adults harder. Bring your medicine list. If you have kidney or liver disease or take other medicines, your pharmacist can still help. Bring a list of everything you take, including what you buy yourself. Thank you to the pharmacists who shared their thoughts with us: Ahuti Lakhani (UK), Bernard Opoku Ware (Ghana), Adwoa Mensah (Ghana), David Pires (Portugal), Romina Takesyan (Argentina), Cecilia Maldonado (Uruguay), and Susan YH Pan (Malaysia).

    #178 - What Is Hereditary Angioedema (HAE)?

    Hereditary angioedema (HAE) is a rare genetic condition that causes attacks of swelling in the skin, the belly, and sometimes the throat. Because it looks like an allergic reaction, it is often missed for years. Kortney and Dr. Payel Gupta are joined by Dr. Marc Riedl, Professor of Medicine and Clinical Director of the US HAEA Angioedema Center at UC San Diego, to set the stage for our three-part series on HAE. We cover what HAE is, what is happening in the body, and symptoms that tell you it is HAE and not an allergy. What we cover in this episode about hereditary angioedema Why HAE is not an allergy. HAE swelling comes from a different system in the body. That's why antihistamines, steroids, and epinephrine don't stop it. HAE is genetic. HAE comes from a change in one gene, and it can be passed from parent to child. Each child of a parent with HAE has a 50-50 chance of having it. About 1 in 4 people are the first in their family to have it, so family testing matters.  What happens in the body. People with HAE don't have enough working C1 inhibitor, the "brakes" on a chemical called bradykinin. Too much bradykinin makes tiny blood vessels leak fluid, and that fluid is the swelling.  HAE swelling and where it happens. It usually doesn't itch or come with hives, and it can last two to five days. It can show up in the hands, face, feet, belly, or throat. Belly attacks can be very painful, and throat swelling needs emergency care. Triggers and warning signs. Injury, dental work, estrogen, and stress can set off attacks. Some people notice a red rash that doesn't itch, or tingling, before the swelling starts. ************ Made in partnership with The Allergy & Asthma Network.

    #177 - Treating Chronic Hives in Special Populations (Women, Pregnancy, Kids, Older Adults & Multiple Conditions

    Chronic hives guidelines give doctors a roadmap for treatment, but not everyone fits the same path. Pregnancy, breastfeeding, menopause, childhood, getting older, and living with more than one chronic condition can all change how chronic spontaneous urticaria (CSU) is treated. Kortney and Dr. Payel Gupta are joined by Dr. Allison Ramsey, an allergist and immunologist, to walk through the special populations section of the chronic urticaria guidelines.  What we cover in this episode about chronic hives in special populations Why it's not your fault. Dr. Ramsey explains how she "absolves" patients of hunting for a trigger, because CSU starts with the immune system, not with anything outside the body. Why women are more burdened by chronic hives. About 70% of people with CSU are women. Estrogen can push the immune system toward autoimmunity, and hives can shift with the menstrual cycle and become less common after menopause. Pregnancy and breastfeeding. Non-drowsy antihistamines are considered safe, and pregnancy data from asthma suggest omalizumab (Xolair) and dupilumab (Dupixent) are too. Adults 65 and older. Higher antihistamine doses can cause sleepiness and raise the risk of falls, so share every medication you take. Biologics don't interact with other medicines. Living with more than one condition. People with CSU are more likely to have other autoimmune conditions. If you also have asthma, eczema, nasal polyps, or food allergy, one medication may treat more than one condition, so tell your doctor about everything. Chronic hives in children. Most hives in kids come from viruses and go away quickly. When kids do have CSU, they often respond better to antihistamines than adults. More resources What is Chronic Urticaria?

    #176: SM Perspectives - The Doctor's Experience of Treating Systemic Mastocytosis

    We hear a lot about the struggles patients face on their systemic mastocytosis journey, the years of normal labs, the feeling of not being believed. But have you ever wondered what that feels like from the doctor's side? Kortney and Dr. Payel Gupta are joined by Dr. Alexander Kim, an allergist and immunologist who co-directs the Mast Cell Disorders Program at UC San Diego, for an honest look at what it's like to sit on the other side of the exam table and untangle a diagnosis of this complex condition. What we cover in this episode about treating systemic mastocytosis Why "your labs look fine" doesn't mean nothing's wrong. Dr. Kim explains why this journey can be challenging for doctors when labs are normal, but symptoms are severe.  Why systemic mastocytosis is still hard to diagnose, even with better tools. SM has a clearer testing path than mast cell activation syndrome (MCAS) does, but the overlap between the two still creates real diagnostic uncertainty in practice. What “dismissiveness” looks like from a doctor's side. From time constraints and busy schedules to the gap between meaning to listen and actually making a patient feel heard. Practical fixes for short appointments. Asking for a double appointment slot, bringing a written summary instead of hundreds of pages of records, and scheduling shorter, more frequent follow-ups instead of one long visit. What each side wants the other to understand. What it takes to build a trusting, lasting relationship with a healthcare provider when you're living with systemic mastocytosis.

    # 175 - Your Mast Cell Disorder Questions, Answered

    Mast cell disorders can feel confusing, especially with so much information floating around online and on social media. In this episode, we cut to the chase and tackle the most common mast cell disorder FAQs, straight from the community. Dr. Dareen Siri joins us to work through community questions on mast cell disorders one by one, from what a mast cell actually is to testing, treatment, diet, and long-term outlook. What we cover in this episode about mast cell disorders What is a mast cell. Dr. Siri breaks down what mast cells do in the body and why an overactive one causes symptoms. The different mast cell disorders. Allergies, autoimmune activation, and clonal disorders like indolent systemic mastocytosis each work differently. Which tests actually matter. Blood tests, the KIT D816V mutation test, and when a bone marrow biopsy comes into play. Plus, should you consider a urine test? Treatment and long-term outlook. What targeted treatment (avapritinib) looks like now, and whether a mast cell disorder shortens your lifespan. Diet, supplements, and bone health. Whether a low-histamine diet helps, what the evidence says about supplements, and why bone density matters long term.

    #174 - Choosing Between Chronic Hives Treatment Options

    How do you decide what is the right medication for you after antihistamines are not working to manage your chronic hives? Dr. David Lang, one of the authors of the new chronic urticaria guidelines (still in review), walks through every advanced treatment option the way he would if he had as much time as possible with a patient in his office. Along with Dr. Gupta, they cover the three treatments available when antihistamines are not enough, what each one asks of you week to week, and how to walk into your appointment ready to choose. Dr. Lang’s patient guide: Choosing an Advanced Treatment for Chronic Hives  What we cover in our episode about  chronic hives treatment What to think about when choosing a medication: benefit, harm, and burden. Dr. Lang explains why these are three different things, and why the one most patients are never asked about is what a treatment costs them in time, appointments, and schedule. The three advanced options side by side. Omalizumab (Xolair), dupilumab (Dupixent), and remibrutinib (Rhapsido) compared on how often you take them, how fast they work, and what the side effects really are. What the scary side effects actually mean. Dr. Lang walks through the anaphylaxis, cancer, and heart risks tied to omalizumab, and explains how likely each one really is. When blood tests for chronic hives come into the picture. Testing will not tell you why you have hives, but it may hint at which of the three treatments is more likely to work for you. Insurance may choose your starting point. All three treatments are approved for chronic hives, so if your plan covers one over another, that is a reasonable place to start, not a compromise. ************ Made in partnership with The Allergy & Asthma Network.
