Inf: Strongyloides Stercoralis: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Strongyloides stercoralis🎧 A clear, high-yield breakdown of this chronic parasitic worm infection – perfect for exam prep and real-life clinical scenarios.🧠 Key Learning Points📌 Definition• Strongyloides stercoralis is a soil-transmitted parasitic roundworm that infects the intestines.• It causes strongyloidiasis, a disease that may be acute, chronic, or life-threatening, especially in immunocompromised patients.📌 Causes & Risk Factors• Contact with contaminated soil – e.g. walking barefoot in endemic areas• Tropical/subtropical regions with poor sanitation• Weakened immune system (HIV, corticosteroids, organ transplant)• Occupational exposure – agriculture, mining💡 Mnemonic: “SLOW” – Soil, Location, Occupational risk, Weak immunity📌 Pathophysiology• Skin penetration by larvae → bloodstream → lungs → coughed up and swallowed → gut colonisation• Auto-infection: larvae reinfect via intestinal wall or perianal skin → continuous life cycle inside host• Risk of hyperinfection syndrome in immunosuppression📌 Symptoms• Often asymptomatic• GI: abdominal pain, diarrhoea, weight loss, nausea• Lungs: cough, dyspnoea, pneumonitis• Skin: urticarial rashes, papulovesicular lesions• Severe: hyperinfection syndrome – sepsis, meningitis, haemorrhage💡 Mnemonic: “GU LASH” – Gut, Urticaria, Lungs, Auto-infection, Sepsis, Hyperinfection📌 Differential Diagnosis• Hookworm, whipworm• Other soil-transmitted helminths• IBS, IBD, tropical sprue, TB, COVID (lung symptoms)📌 Diagnosis• Stool microscopy – detect larvae (often needs serial samples)• Blood eosinophilia• Serology (EIA) – antibody testing• Duodenal fluid sampling• CXR – look for lung complications💡 Mnemonic: “SLAB” – Stool, Larvae ID, Antibodies, Bloods📌 Management• Treat all patients, even if asymptomatic• Ivermectin: 200 mcg/kg/day × 2 days – 97% eradication• Albendazole: 400 mg BD × 3 days (repeatable)• Antihistamines for rash• Hospitalisation for disseminated/hyperinfection cases⚠️ Always screen before steroids/immunosuppression📌 Complications• Hyperinfection syndrome – dissemination beyond lungs/gut• Sepsis, meningitis, severe pneumonia, GI haemorrhage• Death if untreated in immunocompromised📌 Prognosis• Excellent if treated early in immunocompetent individuals• Poor in disseminated infection – high mortality without prompt treatment• Emphasis on prevention and early screening in at-risk patients📎 More MSRA Resources for Strongyloides stercoralis📝 Revision Notes: https://www.passthemsra.com/topic/strongyloides-stercoralis-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/strongyloides-stercoralis-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/strongyloides-stercoralis-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/strongyloides-stercoralis-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/infectious-diseases-for-the-msra/Hashtags#MSRA #MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQ&ANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision #MSRARevisionWebsite #StrongyloidesStercoralis #InfectiousDiseases
