Renal: Haemolytic Uraemic Syndrome: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Haemolytic Uraemic Syndrome (HUS)🎧 A high-yield breakdown of this paediatric renal emergency. Master the classic triad, key triggers, and UK-based management.🧠 Key Learning Points📌 Definition• HUS = triad of microangiopathic haemolytic anaemia, thrombocytopenia, and acute kidney injury• Often follows Shiga toxin-producing E. coli (STEC) infection• Notifiable disease in the UK📌 Causes• Typical HUS (90%): triggered by E. coli O157:H7• Spread via contaminated food/water, farm animals• Atypical HUS: genetic mutations, complement dysregulation, certain drugs (e.g. tacrolimus, ciclosporin)📌 Risk Factors• Children aged 6 months–5 years• Undercooked meat, unpasteurised dairy, animal contact• Summer months, rural areas📎 UK: Children with STEC need 2 negative stools before returning to school📌 Pathophysiology• Shiga toxin damages endothelium → platelet activation → clots → RBC destruction → AKI• Atypical form involves uncontrolled complement activation📌 Symptoms• Starts with diarrhoea, often bloody after 1–3 days• Pallor, fatigue, bruising, oliguria, abdominal pain• Severe cases: confusion, seizures, multi-organ failure📌 Differentials• TTP, DIC, appendicitis, IBD, intussusception, HELLP📌 Diagnosis• FBC (anaemia, low platelets), U&Es, LDH, CRP, LFTs• Stool culture for STEC/Shiga toxin• Urinalysis: haematuria, proteinuria• If atypical: complement studies, ADAMTS13 activity📌 Management• Supportive care: IV fluids, transfusions, dialysis if needed• Avoid antibiotics in STEC-HUS (↑ toxin release)• Atypical HUS: consider plasma exchange, eculizumab📎 Always notify Public Health📌 Prognosis• Most children with typical HUS recover• 5–25% risk of CKD or hypertension• aHUS: higher risk of ESRD, poorer outcomes📌 Prevention• Hand hygiene, cook meat thoroughly, avoid unpasteurised products• Public health surveillance essential• Vaccines for STEC in development but not routine📌 Complications• GI: strictures, perforation, pancreatitis• Neuro: seizures, stroke• Renal: chronic kidney disease, long-term hypertension📎 More MSRA Resources for Haemolytic Uraemic Syndrome📝 Revision Notes:https://www.passthemsra.com/topic/haemolytic-uraemic-syndrome-revision-notes/🧠 Flashcards:https://www.passthemsra.com/topic/haemolytic-uraemic-syndrome-flashcards/💬 Accordion Q&A Notes:https://www.passthemsra.com/topic/haemolytic-uraemic-syndrome-accordion-qa-notes/🚀 Rapid Quiz:https://www.passthemsra.com/topic/haemolytic-uraemic-syndrome-rapid-quiz/🧪 Topic Quiz:https://www.passthemsra.com/quizzes/haemolytic-uraemic-syndrome/🎓 Full Renal Course:https://www.passthemsra.com/courses/renal-for-the-msra/🩺 Powered by PassTheMSRA – structured, UK-based medical revision for doctors and trainees.🌐 Explore more at:https://www.passthemsra.comHashtags#MSRA #MSRARevision #MSRATextbook #MSRAQuiz #MSRAFlashcards #MSRAQandANotes #MSRAAccordions #MSRAOnlineRevision #Renal #HaemolyticUraemicSyndrome #HUS
