Haem: Paraproteinaemia: Free MSRA Podcast

🎧Paraproteinaemia(Monoclonal Gammopathy) – Uncovering the Hidden Clues in the Blood 🩸🧬In this high-yieldDeep Dive episode, we explore Paraproteinaemia— the mysterious appearance of abnormal monoclonal proteins in the blood. From MGUS to multiplemyeloma, we untangle the diagnostic process, clinical clues, and management pathways that are key for both your MSRArevision and clinical understanding. If you've ever felt overwhelmed by serum electrophoresis or unsure when to suspect a paraprotein, this one's for you.🧠What You'll Learn:• Definition: – Paraproteinaemia= presence of abnormal monoclonal immunoglobulins (M proteins) in the blood – Often results from clonal expansion of plasma cells or B lymphocytes• Spectrum of Disease: – Ranges from MGUS (monoclonal gammopathy of undetermined significance) – To multiple myeloma, Waldenström’s macroglobulinaemia, and POEMS syndrome – Can also be associated with autoimmune diseases (RA, SLE), infections (hepatitis, HIV), and solid tumours (breast, colon)• Pathophysiology: – Faulty clone of plasma cells mass-produces a single abnormal immunoglobulin – These paraproteins can:  • Impair immune function  • Disrupt bone marrow haematopoiesis   • Cause end-organ damage (esp. kidneys, nerves, bones)🩺 Clinical Features – Think "BRAINS":A helpful mnemonic to remember when to suspect a paraprotein:B – Bone disease (bone/back pain, lytic lesions)R – Renal impairment (high creatinine, low eGFR)A – Anaemia (or pancytopenia)I – Infections (recurrent or severe)N – Neuropathy (numbness, tingling)S – Systemic signs (fatigue, hypercalcaemia, weight loss)📊 Investigations:• Blood tests: SPEP (serum protein electrophoresis) for Mspike – Immunofixation electrophoresis (IFE) to typethe paraprotein – Serum free light chain assay – FBC, calcium, renal function, ESR• Urine tests: – UPEP and Bence-Jones proteins• Bone Marrow Biopsy: – Quantifies %plasma cells, identifies clonality – Helps distinguish MGUS vs myeloma• Imaging: – Skeletal survey, low-dose CT, or MRI to assess for bone lesions💊Management Overview:• MGUS: – No treatment, but lifelong monitoring due to ~1%/year progression risk – Monitor: FBC, renal function, calcium, SPEP every 6–12 months• Symptomatic Disease (e.g. Myeloma): – Chemotherapy, immunomodulatory drugs (thalidomide, lenalidomide) – Targeted agents: bortezomib, daratumumab – Autologous stem cell transplantation in eligible patients – Bisphosphonates for bone protection  – Supportive care: blood transfusions, infection prevention📈 Prognosis & Monitoring:• MGUS: – ~1% per year risk of progression – Higher risk if IgM or abnormal free light chain ratio present• Multiple Myeloma: – 5-year survival ~52% (2020 data, improving with modern therapy)• Key complications: – Kidney injury,amyloidosis – Immunosuppression→ infections – Hyperviscositysyndrome – Neuropathy – Treatment sideeffects (cytopenias, neuropathy)📚Memory Aids:• BRAINS – Bone pain, Renal failure, Anaemia,Infections, Neuropathy, Systemic signs• SPEP + UPEP + IFE = key diagnostics• MGUS <10%, Myeloma>10%, think “10% = tipping point”📝Revision Resources:• 📘 Revision Notes:https://www.passthemsra.com/topic/paraproteinaemia-monoclonal-gammopathy-revision-notes/• 🃏 Flashcards:https://www.passthemsra.com/topic/paraproteinaemia-monoclonal-gammopathy-flashcards/• 📂 Accordion Q&A Notes:https://www.passthemsra.com/topic/paraproteinaemia-monoclonal-gammopathy-accordion-qa-notes/• 🎯 Rapid Quiz:https://www.passthemsra.com/topic/paraproteinaemia-monoclonal-gammopathy-rapid-quiz/🌐Main Sites:https://www.passthemsra.com . https://www.freemsra.com #MSRA #Paraproteinaemia #MonoclonalGammopathy #MGUS #MultipleMyeloma #MSRAFlashcards#Haematology #PassTheMSRA #BRAINS #SerumProteinElectrophoresis#MyelomaDiagnosis #FreeMSRA #PlasmaCellDisorders #MedicalPodcast #MSRARevision#MSRAOnlineResources
