 🎧Neutropenia – MSRADeep DiveWelcome to yourbite-sized, high-yield revision session on neutropenia– a crucial concept for understanding infection risk and immune suppression. 🔬What Is Neutropenia?A low neutrophil count – these are the whiteblood cells that fight off bacteria.🧮Normal ANC (absoluteneutrophil count) = 2.0–7.5 × 10⁹/L<1.5 = Neutropenia1.0–1.5 = Mild0.5–1.0 = Moderate<0.5 = Severe (very high infection risk) 🧠Mnemonic:"No NEUTRs? No DEFENCE!" 🚨Causes of NeutropeniaGrouped into 3 keymechanisms:🔨 Reduced production (e.g. chemotherapy, marrow failure)🔥 Increased destruction (e.g. autoimmune, drugs)🧲 Sequestration (e.g. hypersplenism)🧠Mnemonic: BAD CV MNHRG• Bone marrow disorders• Autoimmune diseases (e.g. SLE)• Drugs (e.g. clozapine, carbimazole)• Chemotherapy• Viral infections (EBV, HIV, Hepatitis)• Medications• Nutritional (B12, folate)• Hemodialysis• Rheumatological• Genetic (e.g. congenital neutropenias) 👶Benign EthnicNeutropeniaCommon in Afro-Caribbean populationsNaturally lower neutrophil counts🚫 Not associated with increased infection riskImportant to avoid over-investigation! 🧬Risk Factors•Chemotherapy/radiation• Bone marrowdisorders• Autoimmunediseases• Viral infections• Certain meds (e.g.clozapine)• Geneticpredisposition/family history 🦠Clinical FeaturesNeutropenia itselfis asymptomaticSymptoms come from infections:• Fevers, chills• Mouth ulcers• Skin infections• Pneumonia, sorethroat• Recurrent orunusually severe bacterial infections🧠Think: "Low NEUTS = More GERMS" 🧪Investigations🧾 Full blood count (FBC)🔬 Blood film – morphology🦴 Bone marrow biopsy – if marrow disease suspected🧬 Genetic testing – if congenital🧪 Autoimmune panels – ANA, RF🔎 Additional tests based on suspected cause 💊Management🎯 Treat the causeStop causative drugsManage autoimmune/viral disorders💉 G-CSF (granulocyte colony stimulating factor)Boosts neutrophil production💊 Infection treatmentFebrile neutropenia = Emergency → IV broad-spectrum antibiotics🛡️ Infection preventionHand hygieneAvoiding sick contactsProphylactic antibiotics/antifungals in some cases 🔮Prognosis🌟 Excellent if cause is self-limiting (e.g. post-viral)🤒 More guarded if linked to malignancy or marrow failure⏳ Depends on severity + success of treating underlying issue ⚠️ComplicationsSevere infection → sepsis → ICUOpportunistic infections (fungal, bacterial)Complications of underlying cause (e.g. SLE, leukaemia)🧠Key Message:Low neutrophils =high infection risk.Recognise early.Investigate wisely. Act fast. 🎯MSRA Resources forNeutropenia📝 Revision Notes:https://www.passthemsra.com/topic/neutropaenia-revision-notes/🧠 Flashcards:https://www.passthemsra.com/topic/neutropaenia-flashcards/❓ Q&A Notes:https://www.passthemsra.com/topic/neutropaenia-accordion-qa-notes/🔥 Rapid Quiz:https://www.passthemsra.com/topic/neutropaenia-rapid-quiz/🧪 Practice Quiz:https://www.passthemsra.com/quizzes/neutropaenia/ #MSRA #Neutropenia#MSRAHaematology #MSRARevision #MSRAQuiz #GCSF #FebrileNeutropenia#BloodDisorders #HaematologyMSRA #PasstheMSRA #DeepDivePodcasts
