Haem: Von Willebrand's Disease: Free MSRA Podcast

🎧Deep Dive: VonWillebrand’s Disease (VWD) – MSRA High-Yield HaematologyEver wonder why somepeople bruise easily or get nosebleeds that just don’t stop? It could be Von Willebrand’s Disease – the most common inherited bleeding disorder. Inthis episode, we break it all down clearly, efficiently, and with exam-focused tips to help you master it for theMSRA and clinical life. 🧬What is VonWillebrand’s Disease (VWD)?VWD is a genetic bleeding disorder caused by adeficiency or dysfunction of von Willebrandfactor (VWF) – a protein vital for:1️⃣Platelet adhesion at injury sites2️⃣Protecting factorVIII from degradation💡Analogy: VWF is the glue forplatelets and thebodyguard for factor VIII. 📊VWD Types – MemoryHooks Included!🔹 Type 1 (Volume Down):• Most common(60–80%)• Quantitativedefect – ↓ amount of VWF🔹 Type 2 (Function Fails):• Qualitative defect– VWF doesn’t work right• Subtypes: • 2A – Absentmultimers • 2B – Bindsspontaneously (risk of thrombocytopenia) • 2M – Misfitbinding • 2N – No factorVIII binding (mimics mild haemophilia A)🔹 Type 3 (Totally Absent):• Severe, almost no VWF• Autosomalrecessive🧠Mnemonic Recap:• 1 = Volume down• 2 = Function fails  • 2A = Absentmultimers  • 2B = Bindsspontaneously  • 2M = Misfitbinding  • 2N = No FVIIIbinding• 3 = Totally absent 🔍Symptoms & Signs• Easy bruising• Frequent/prolongednosebleeds (epistaxis)• Menorrhagia in women• Prolonged bleedingpost-dental work or minor injuries• GI bleeding (lesscommon)• Severe: jointbleeds (type 3)🧠 Think: Platelet-type bleeding + factor VIII impact 🧪Diagnosis – What toOrderVWF antigen – measures amountVWF activity – ristocetin cofactor assayFactor VIII level – often ↓APTT – may be prolongedGenetic testing – confirms type/subtypePlatelet function tests – rule out other disordersVWF multimer analysis – for type 2 classification 👩‍⚕️Management Summary –Know the Strategy🩸 Mild Bleeds• Tranexamic acid – stabilises clots💉 Desmopressin (DDAVP)• Triggers VWF +FVIII release from endothelium• Effective for type 1• ⚠️ Avoid in type 2B and type 3• Trial dose oftenneeded🧬 Factor Replacement Therapy• Plasma-derived orrecombinant VWF concentrates• Essential in type 3, major bleeds, or surgery💊 Hormonal Options (for Menorrhagia)• COCP, Mirena IUS,or cyclic progesterone🩹 General Measures• Avoid NSAIDs• Local pressure,tranexamic mouthwash• Plansurgery/delivery with haematology input 📈Epidemiology &Risk• Up to 1% prevalence – mostcommon inherited bleeding disorder• Often undiagnosedor mild• Type O blood =lower baseline VWF• Women more oftendiagnosed due to menorrhagia ⚠️Complications (If untreated or undiagnosed):• Iron-deficiencyanaemia• Arthropathy (rare,from joint bleeds)• Peripartumhaemorrhage• Life-threateningbleeding in major trauma/surgery✅BUT – with diagnosis + personalised management, most people live full, healthylives. 📚VWD MSRA StudyResources📝Revision Noteshttps://www.passthemsra.com/topic/von-willebrands-disease-revision-notes/🧠Flashcardshttps://www.passthemsra.com/topic/von-willebrands-disease-flashcards/❓Accordion Q&ANoteshttps://www.passthemsra.com/topic/von-willebrands-disease-accordion-qa-notes/🔥Rapid Quizhttps://www.passthemsra.com/topic/von-willebrands-disease-rapid-quiz/🧪Quiz Bankhttps://www.passthemsra.com/quizzes/von-willebrands-disease/ 💬Final ThoughtDon’t ignore “just a nosebleed” or “bad periods.” Recognising subtle bleeding symptoms in yourselfor family can lead to early diagnosis, safer care, and betteroutcomes.For more high-yieldhaematology and MSRA-ready content, visit:🌐passthemsra.com & freemsra.com#MSRA#VonWillebrandsDisease #VWD #Haematology #MSRARevision #PasstheMSRA #FreeMSRA#Desmopressin #TranexamicAcid #BleedingDisorders #HighYieldMedicine#MSRAFlashcards #MSRAQuiz #MedicalPodcast
