🎧 MSRA DEEP DIVE PODCAST – Rheumatoid Arthritis (RA)The focused, high-yield revision you need for the MSRA🧠 Key Learning Points📌 Definition• Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disorder that mainly targets the synovial lining of joints, causing pain, swelling, stiffness, and long-term joint damage.• It is systemic, with extra-articular features affecting multiple organs.📌 Causes & Risk Factors• Multifactorial:Genetic: HLA-DR4 gene (family history)Environmental: Smoking (major), obesity, silica exposureImmunological: Abnormal immune response (autoimmunity)• Mnemonic: GEI (Genetic, Environmental, Immunological)• More common in women (3:1), peak onset 40–60 years, but can occur at any age📌 Pathophysiology• The immune system mistakenly attacks the synovium → inflammation (cytokines) → joint destruction• Symmetrical small joint involvement (hands, feet) typical• Can lead to joint deformities and systemic involvement over time📌 Clinical Features• Morning stiffness (>30 minutes), improves with use• Symmetrical joint pain, swelling (especially small joints: MCP, PIP, wrists, MTP)• Systemic: fatigue, weight loss, low-grade fever• Extra-articular: lungs (ILD, pleural effusion), heart (pericarditis), skin (nodules), eyes (dry, scleritis), blood (anaemia), nerves (carpal tunnel), and more• Mnemonic for differentials: Go Slave PC FLAMES (Gout, OA, SLE, Viral, Psoriatic, Connective tissue diseases, Fibromyalgia, Lyme, etc.)📌 Diagnosis• Clinical assessment + bloods + imaging• Bloods:Rheumatoid factor (RF) (70%, not specific)Anti-CCP antibodies (more specific, predicts prognosis)ESR, CRP raised• Imaging:X-rays of hands/feet (baseline, erosions)Ultrasound/MRI (synovitis, early damage)• Mnemonic for workup: BLIMP ACR NICEBloods, Lab, Imaging, Markers, Physical examACR/EULAR 2010 criteria (≥6/10 = RA), NICE referral guidelines📌 Management• First-line:DMARDs (methotrexate is first choice; also sulfasalazine, hydroxychloroquine, leflunomide)Short-term steroids for flares• Second-line:Biologic agents (anti-TNF: adalimumab, etanercept, infliximab; others as per NICE guidance)• Other:NSAIDs for symptom reliefPhysiotherapy, exercise, occupational therapyOrthopaedic surgery for severe damageMonitor with DAS28 scoreAddress cardiovascular risk, bone health (osteoporosis)• Mnemonic for treatment: DEMARDS Biologics, No surgery (unless needed), Monitor, Diet, Referral📌 Complications & Prognosis• Joint deformity, functional loss, disability• Osteoporosis• Cardiovascular disease (major mortality risk)• Infections (due to immunosuppression)• Extra-articular manifestations (lung, heart, eyes, skin, nerves)• Drug side effects: GI (NSAIDs), liver (methotrexate), infection, osteoporosis (steroids), rare malignancy risk• Early diagnosis and aggressive treatment = best outcomes📎 MSRA Rheumatoid Arthritis Revision Resources📝 Revision Notes:https://www.passthemsra.com/topic/rheumatoid-arthritis-revision-notes/💬 Accordion Q&A Notes:https://www.passthemsra.com/topic/rheumatoid-arthritis-accordion-qa-notes/🧠 Flashcards:https://www.passthemsra.com/topic/rheumatoid-arthritis-flashcards/🚀 Rapid Quiz:https://www.passthemsra.com/topic/rheumatoid-arthritis-rapid-quiz/🎓 Full Quiz:https://www.passthemsra.com/quizzes/rheumatoid-arthritis/#MSRA #RheumatoidArthritis #Autoimmune #MSRARevisionNotes #MSRAQuiz #MSRAFlashcards #MSRAQandANotes #MSRAAccordions #Musculoskeletal #MSRAExam #Rheumatology #MSRAOnlineRevision
