Gastro: Autoimmune Hepatitis: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – AutoimmuneHepatitis🎧 A clear, high-yield breakdown of this chronic immune-mediated liver condition – perfect for exam prep and real-life clinicalscenarios. 🧠 Key Learning Points📌 Definition•Autoimmune Hepatitis (AIH) is a chronicinflammatory liver disease caused by the body’s immune system mistakenly attacking hepatocytes, leading toliver damage.📌 Causes & Risk Factors•Likely multifactorial: genetic predisposition +immune dysregulation + environmental triggers•HLA types: HLA-B8, HLA-DR3•Viral infections or drug exposures may trigger onset•More common in females and those with other autoimmune diseases (e.g. SLE,thyroiditis, coeliac)Mnemonic: “GENIE”– Genetics, Environment, Non-specific triggers, Immune dysregulation, Estrogen(female bias)📌 Pathophysiology•Immune system produces autoantibodiestargeting liver cells•Ongoing inflammation → hepatocyte destruction → fibrosisand cirrhosis•Autoantibodies include ANA, ASMA, anti-LKM1,anti-SLA📌 Symptoms•Often non-specific or asymptomatic•Classic signs: Fatigue, jaundice, RUQ pain,hepatomegaly•Systemic features: Arthralgia, rash,amenorrhoea, feverMnemonic: “JAUNDICE”– Jaundice, AST/ALT raised, Unwell, No clear trigger, Deficient periods, Itchyskin, Cirrhosis risk, Extra symptoms📌 Differential Diagnosis•Viral hepatitis (B, C)•Drug-induced liver injury•Primary biliary cholangitis (PBC)•Primary sclerosing cholangitis (PSC)•Alcoholic hepatitis•Wilson’s disease / haemochromatosis📌 Diagnosis•Liver function tests: raised ALT/AST,often disproportionately high•High IgG (polyclonalhypergammaglobulinaemia)•Autoantibodies: ANA, ASMA, anti-LKM1, anti-SLA•Liver biopsy: shows interface hepatitis, piecemeal/bridging necrosis•Imaging to rule out structural liver causesQuick Tip: ANA + ASMA = think Type 1 AIH; Anti-LKM1 = Type 2 AIH (kids); Anti-SLA = Type3 AIH📌 Management•Induction: Prednisolone (oralcorticosteroid)•Maintenance: Azathioprine (ormycophenolate if intolerant)•Monitor: LFTs, autoantibodies, IgG, FBC,bone density, glucose•Vaccinate before immunosuppression (HepA/B)•DEXA and eye checks due to steroid risk•Liver transplant in severe ornon-responsive cases•Ongoing monitoring for relapse and treatment side effects📌 Complications•Cirrhosis and liver failure•Hepatocellular carcinoma (HCC) – esp. incirrhosis•Portal hypertension and varices•Immunosuppression-related issues (e.g. infections, bone loss, diabetes)📌 Prognosis•Favourable with early diagnosis andconsistent immunosuppressive treatment•Without treatment, high risk of progression to cirrhosis or death•Lifelong condition requiring long-termmonitoring and therapy 📎 More MSRA Resources forAutoimmune Hepatitis📝 Revision Notes: https://www.passthemsra.com/topic/autoimmune-hepatitis-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/autoimmune-hepatitis-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/autoimmune-hepatitis-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/autoimmune-hepatitis-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/gastroenterology-for-the-msra/ Hashtags#MSRA#MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards#MSRAQandANotes #MSRAAccordions #MultiSpecialtyRecruitmentAssessment#MSRAOnlineRevision #MSRARevisionWebsite #AutoimmuneHepatitis
