Baby Eczema Breakthrough: Crisco Barrier + Allergy Drops (Follow-Up w/ Abby Z) | My Allergist Dad

In this follow-up episode of My Allergist Dad, Drew and Dr. Z welcome back Abby to share updates on her infant son Joey’s progress with eczema and multiple allergies. Abby describes Joey’s early severe atopic dermatitis, egg-triggered hives, positive tests to dog, pistachio, and cashew, and how a daily routine improved his skin: nightly baths, ceramide baby moisturizer, heavy Crisco layering, and prescription topical treatment when needed. They discuss giving baked egg mini muffins weekly, maintaining peanut exposure with Bamba, and offering other common allergens weekly, plus a daily probiotic. Dr. Z explains why improving the skin barrier matters, and why sublingual immunotherapy drops (currently dog only) have a strong safety profile and may help build tolerance; Abby reports Joey now has minimal reactions around dogs.00:00 Crisco Eczema Breakthrough00:46 Show Intro and Guests04:33 Joey Allergy Backstory06:57 Daily Barrier Routine08:24 Baked Egg and Drops09:37 Dog Allergy Mythbusting10:52 Early Desensitization Science12:59 Diet Variety and Microbiome16:15 Taking Control Long Term18:57 When to Start Food Drops19:27 Drops Versus Shots20:21 Why Sublingual Is Safer21:36 Sticking With The Routine22:00 Allergy Season And Dog Prep23:26 Dolly And Joey Updates24:52 Progress And Real Life Exposure26:49 Baked Egg To Pancakes29:19 Sourdough And Baking Talk31:08 Rocky Ring Bearer Jokes32:12 Wrap Up And Disclaimer 📩 Have a question for the show?Email: myallergistdad@gmail.com

Allergy & Dermatology Overlap: Hives, Dermatitis, and The Skin of Color Clinic w/ Dr. Elnaz Firoz

Drew and Dr. Z are joined by Dr. Elnaz Firoz, Medical Director of Dermatology at The Miriam Hospital and founder of the Skin of Color Clinic, to discuss the major overlap between dermatology and allergy and why fragmented, multi-specialist care can delay diagnosis. They cover the importance of thorough skin exams, challenges recognizing inflammation and eczema on darker skin, and common issues in skin of color such as pigment changes, hidradenitis suppurativa, and keloids. The conversation explores how “allergy” can include drug hypersensitivity and immune reactions like leukocytoclastic vasculitis, plus rising urticaria and contact dermatitis (including from wipes). They discuss insurance barriers, the impact of stress and lifestyle on inflammation, concerns about widespread Botox use and developing resistance, and practical sun protection guidance emphasizing mineral sunscreens and protective clothing.00:00 Allergies and Skin Intro00:43 Meet Dr. Firoz01:58 Specialists and Care Coordination04:30 Why Full Skin Exams Matter07:11 Skin of Color Clinic Focus08:18 Keloids Explained12:01 Acne and Cosmetic Bias14:41 Drug Pricing and Access18:49 Allergy Driven Skin Reactions20:32 Vasculitis and Urticaria Basics26:21 Biologics and Diagnostic Pitfalls28:31 Medical Progress and Inflammation32:42 Root Cause Allergies32:53 Hormones Lifestyle Asthma34:43 Stress Triggered Hives36:57 Lifestyle Inequality Health39:51 Botox Immune Risks45:43 Food Additives Mast Cells48:02 Mineral Sunscreen Basics50:34 Wrap Up And Credits📩 Have a question for the show?Email: myallergistdad@gmail.com

Eosinophilic Esophagitis (EoE), Food Triggers, and the Gut–Immune Connection (with Dr. Alan Epstein)

In this episode of My Allergist Dad, Drew and Dr. Z welcome gastroenterologist Dr. Alan Epstein to discuss gut health and its relationship to overall health, focusing on eosinophilic esophagitis (EoE) and why it has become more common since the 2000s. Dr. Epstein explains how EoE is diagnosed by endoscopy and biopsy (over 15 eosinophils per high-power field), how it can cause food impactions, and why triggers can be unclear, sometimes involving foods and possibly environmental factors. They review treatments including proton pump inhibitors, swallowed/topical steroids like budesonide, and dupilumab as a later option, plus the challenges of elimination diets. The conversation expands to celiac testing, microbiome diversity and antibiotics, vagus nerve signaling, and using vibration controlled transient elastography (VCTE) to detect fatty liver early to prevent fibrosis and cirrhosis.00:00 Liver Scan Wakeup Call00:52 Episode Preview and Intro01:45 Meet Dr Alan Epstein03:09 Medicine Beyond Silos06:11 What Is EoE15:46 Treating EoE Options17:08 Root Causes and Diet Triggers20:34 Celiac vs Gluten Sensitivity23:00 Wheat Around the World25:16 Old School Swallow Tests25:50 Why EoE Is Rising26:56 Obesity Toxins and Fatty Liver28:30 FibroScan Explained30:14 EoE Food Impaction Basics32:17 Endoscopic Removal Stories36:13 Ancient Microbiome Findings40:12 Fermented Foods vs Probiotics41:55 GLP-1s and Root Causes45:48 Healthcare System Squeeze48:50 Wrap Up and Disclaimers 📩 Have a question for the show?Email: myallergistdad@gmail.com

How Stress Impacts Allergies, Hives & Your Immune System (with Psychiatrist Dr. Bryson Lochte)

This episode of My Allergist Dad explores how mental stress can affect the body, immune system, and allergies. Drew and Dr. Z are joined by Santa Monica psychiatrist Dr. Bryson Lochte, who discusses treating root causes rather than only symptoms, including psychotherapy, ketamine-assisted psychotherapy, and tools like meditation and breathwork. Dr. Z describes patients with persistent hives, itching, and breathing complaints that don’t respond well to escalating medications, often alongside major life stressors, and explains stress-related sympathetic and cortisol effects, anxiety–allergy connections, and downstream impacts like microbiome changes and mast-cell activation. The conversation covers how stress can worsen existing allergies, how anxiety can mimic asthma or contribute to vocal cord dysfunction, and why a more interconnected, holistic approach is needed alongside standard medical treatment.00:00 What Stress Really Means00:57 Meet Dr. Bryson Lochte01:27 Show Intro Theme03:09 Stress And Allergy Flare Ups08:05 Treating Roots Not Symptoms10:36 Three Ways We Handle Distress12:26 Breathwork And Hidden Emotions14:35 Breathing Problems Or Anxiety16:26 Kids Animals And Culture19:30 Anxiety Allergies Chicken Egg22:04 Immune Domino Effects26:26 Holotropic Breathwork Explained29:48 Wrap Up Final Thoughts32:25 Medical Disclaimer📩 Have a question for the show?Email: myallergistdad@gmail.com

New Food Allergy Test That Predicts Accurate Reactions w/ Dr. Jonathan Friedlander of Atanis Biotech

On this episode of My Allergist Dad, Drew and Dr. Z talk with Dr. Jonathan Friedlander, Chief Business Officer at Atanis Biotech about FAST-PASE®, a diagnostic test that uses a stable, functional engineered mast cell line to measure whether a patient’s serum actually triggers mast cell activation when exposed to specific allergens. Unlike basophil activation testing that requires fresh whole blood, FAST-PASE® removes cells, uses serum to sensitize lab mast cells with the patient’s IgE, IgG, and other factors, then adds allergens at multiple concentrations and measures activation, aiming to reduce false positives from IgE-only tests and better predict clinical reactivity and thresholds for oral food challenges. They discuss applications to food allergy, immunotherapy monitoring (OIT/SLIT), alpha-gal syndrome and widespread sensitization vs true allergy, and broader future uses for environmental allergens and drug allergy, plus Jonathan’s recent Capitol Hill visit and plans to start testing at Dr. Z’s clinic.00:00 Basophil Test Limits00:59 Why This Test Matters01:56 Show Intro and Guest04:18 Origins of Atanis Biotech06:16 Immortal Mast Cells08:08 How FAST-PASE® Works10:08 Compared to IgE Tests13:32 IgG Protection Nuance16:02 Desensitization and Challenges17:55 Alpha Gal Confusion19:25 Alpha Gal Biology21:04 Need Functional Testing22:37 Tick Season Anxiety23:12 Alpha Gal Case Story23:52 Hidden Alpha Gal Exposures24:31 Gene Edited Pig Organs24:46 Sausage Trial And Food Questions26:26 Therapies And Monitoring Progress28:30 Beyond Food Allergens29:35 Drug Allergy And Testing Limits30:54 Advocacy On Capitol Hill32:56 Access And Allergist Shortage34:07 Mast Cell Confusion And Root Causes36:55 Launching In Europe Too39:15 Wrap Up And Next Steps40:24 Clinic Testing And Farewell📩 Have a question for the show?Email: myallergistdad@gmail.com
