🔍 DEEP DIVE: Recurrent Miscarriage for the MSRA🎯 Master the high-yield essentials for this sensitive yet critical topic – packed with stats, causes, tests, and evidence-based treatments.🧠 Key Learning Points📌 Definition• Recurrent miscarriage = 3 or more consecutive pregnancy losses before 24 weeks gestation• Occurs in ~1% of women• Risk increases with maternal age💡 Mnemonic: “3 Before 24”📌 Causes & Risk Factors• Genetic: Parental chromosomal abnormalities (e.g. balanced translocations)• Anatomical: Uterine abnormalities (e.g. septate uterus)• Endocrine: PCOS, poorly controlled diabetes• Immune: Antiphospholipid syndrome (APS) – treatable!• Thrombophilic: Protein C/S deficiencies, Factor V Leiden• Infections: Bacterial vaginosis → ↑ 2nd trimester losses• Lifestyle: Smoking, alcohol, obesity💡 Mnemonic: “GATE IS LIT” – Genetics, Anatomy, Thrombophilia, Endocrine, Infection, Smoking/Lifestyle, Immune, Trauma📌 Pathophysiology• Underlying factors interfere with implantation or fetal development• Leads to early or mid-trimester pregnancy loss📌 Clinical Features• History of ≥3 consecutive losses before 24 weeks• Symptoms during loss: bleeding, pain, passage of tissue• Loss may mimic sporadic miscarriage📌 Differential Diagnoses• Ectopic pregnancy• Molar pregnancy• Cervical insufficiency📌 Investigations🔬 After 3rd miscarriage:• Products of conception (POC) testing for chromosomal abnormalities• If abnormal → Parental karyotyping• Pelvic ultrasound ± HSG/hysteroscopy for uterine issues• APS screening: If ≥3 1st trimester OR any 2nd trimester loss• Inherited thrombophilia screen: For 2nd trimester losses• Cervical scans: If cervical incompetence suspected🚫 NOT routinely recommended:• Diabetes screen• Thyroid, prolactin, TORCH• General inherited coagulopathies💡 Know what not to order – saves marks in exams!📌 Management🛠 General principles:• Treat underlying cause if found (e.g. surgery, anticoagulants, hormone therapy)• Emotional support & counselling• Close monitoring in future pregnancies💊 Pharmacological:• Heparin + low-dose aspirin: Improves live birth rate in primary APS (↑ to ~70%)• LMWH: ❌ No benefit in inherited thrombophilia• Metformin: Mixed evidence for PCOS – not currently recommended• Progesterone: Mixed data – may help in unexplained RM (per Cochrane review)• hCG: No benefit• Immunotherapy: No significant benefit✂️ Surgical:• Cervical cerclage: For 2nd trimester loss due to cervical insufficiency in singleton pregnancies• Abdominal cerclage: Pre-pregnancy option with growing evidence📌 Prognosis• Many couples go on to have a successful pregnancy• Depends on cause and whether effective treatment is available• Emotional toll is significant – ongoing support essential📎 Further Revision Links📝 Revision Notes:https://www.passthemsra.com/topic/recurrent-miscarriage-revision-notes/🧠 Flashcards:https://www.passthemsra.com/topic/recurrent-miscarriage-flashcards/💬 Accordion Q&A:https://www.passthemsra.com/topic/recurrent-miscarriage-accordion-qa-notes/🚀 Rapid Quiz:https://www.passthemsra.com/topic/recurrent-miscarriage-rapid-quiz/🎯 Quiz:https://www.passthemsra.com/quizzes/recurrent-miscarriage/🎓 Full Course:https://www.passthemsra.com/courses/obstetrics-and-gynaecology-for-the-msra/#MSRA #MSRARevisionNotes #MSRAFlashcards #MSRAQuestionBank #RecurrentMiscarriage #ObsAndGynae #MSRAQuiz #APS #EarlyPregnancyLoss #MSRAAccordions #MSRAOnlineRevision #MultiSpecialtyRecruitmentAssessment
