🎧Deep Dive: SickleCell Crises – MSRA High-Yield Haematology

In this episode, webreak down sickle cell crises – whatthey are, why they happen, and how to recognise and manage them. Whether you’rerevising for the MSRA or sharpening yourclinical understanding, this fast-track session covers everything you need to recall the essentials with confidence.

🧬What is a Sickle CellCrisis?

A sickle cell crisisis an acute complication of sickle cell diseasecaused by sickling of red blood cells → vascular blockage → tissue ischaemia and pain. It’s a clinicalemergency that requires rapid recognition and targeted management.

🧠Types of Crises (5Main Types)

1. Thrombotic / Vaso-occlusive – most common, severe pain due to vessel blockage
2. Sequestration – pooling of blood in spleen/lungs → sudden anaemia
3. Acute Chest Syndrome – occlusion in pulmonary vessels → chest pain, hypoxia, infiltrates
4. Aplastic Crisis – triggered by parvovirus B19 → ↓ RBC production
5. Haemolytic Crisis – sudden ↑ RBC breakdown → worsening anaemia

🧠Mnemonic: “The Sickle Crises Are Horrid”→ T-S-C-A-H

🔥Key Triggers – DITSH

• Dehydration

• Infection

• Temperature extremes

• Stress

• Hypoxia

🧠Mnemonic: DITSH triggers sickling!

🧪PathophysiologySnapshot

• Mutation → HbS → polymerises when deoxygenated

• RBCs → sickleshape = rigid + sticky

• Vaso-occlusion → ischaemia + pain + inflammation

• Recurrent crises →long-term organ damage

👩‍⚕️Who’s Affected?

• Highest inindividuals of African, Caribbean, MiddleEastern, or South Asian descent

• ~15,000 peopleaffected in the UK

• Most crises seenin those with sickle cell anaemia (HbSS)

🩺Clinical Presentation

• Severe pain – long bones, back, joints, abdomen

• Acute chest syndrome – chest pain, SOB,infiltrate

• Splenic sequestration – enlarged spleen +sudden anaemia

• Other clues – fever, priapism, neuro signs(stroke), jaundice

🔍Differentials toConsider

• Bone fracture

•Appendicitis/gallstones

• Renal colic

• Vasculitis

• Acute abdomen

• Infection/sepsis

🧪Investigations

✔️FBC – anaemia, ↑ WCC, reticulocyte count

✔️Retics – high in sequestration, low in aplastic

✔️Blood smear – sickled cells

✔️CXR – check for acute chest syndrome

✔️Other – infection screen, renal/liver function, imagingif needed

💊Management (UKPractice)

🎯Goals:

1. Control pain
2. Treat triggers
3. Prevent complications

🩹Stepwise Pain Relief

Paracetamol → NSAIDs→ Opioids/PCA

💧Fluids – oral/IV

🦠Antibiotics – if infection suspected

💉Oxygen – if SpO₂ low

💉Transfusion – in severe anaemia, acute chest, pregnancy

💊Hydroxyurea – long-term to prevent recurrent crises

🧠Mnemonic: HOT-FAT

Hydration, Oxygen,Treat cause, Fluids, Analgesia, Transfusion (when needed)

⚠️Complications

•Stroke 🧠

•Acute chest syndrome 💨

• Chronic pain

• Renal/liverdysfunction

• Gallstones

• Splenic infarction→ ↑ infection risk

• Priapism

• Leg ulcers

• Osteonecrosis

• Recurrentinfections

• Early mortality ifpoorly managed

🎧Post-ThromboticSyndrome – Long-Term Leg Complications After DVT 🦵💥

Welcome to anotherfocused MSRA Deep Dive — today we’re tackling Post-ThromboticSyndrome (PTS). If you've ever wondered why leg pain, swelling, or skinchanges persist long after a DVT, this episode is essential. We're breakingdown the why, who, how, and what to do — so whether you’re revising forthe MSRA or want clarity on a complexvascular issue, this is for you.

🧠What You’ll Learn:

• Definition:

 – PTS is a chronic condition that can develop after a DVT

 – Caused by long-term damage to vein valves and walls →leads to chronic venous hypertension

• Pathophysiology:

 – Residual clot +inflammation damages valves

 – Leads to venous reflux, venoushypertension, and tissue hypoxia

 – Over time →capillary leakage, swelling, skin changes, fibrosis

• Key Risk Factors:

 – Older age, obesity,recurrent DVTs

 – Inadequate ordelayed anticoagulation

 – Thrombophilia,cancer, prolonged immobility (flights, bed rest)

 – DVT in proximal veins (e.g. femoral, iliac) = higherPTS risk

🩺Clinical Features:

• Symptoms:

 – Chronic leg pain,swelling, heaviness

 – Worse at end ofday / with standing

 – Improved with leg elevation

 – Cramps, fatiguein the limb

• Signs:

 – Hyperpigmentation, lipodermatosclerosis (woody skin texture)

 – Varicose veins, venouseczema, venous ulcers in severecases

 – Skin itching(pruritus)

📊Investigations:

• History & Examination:

 – Ask aboutprevious DVT

 – Look forpersistent swelling, skin changes, varicosities

• Duplex Ultrasound:

 – Confirms venous reflux, residualthrombus, or valve dysfunction

 – Main non-invasivetool for diagnosis

• Advanced Imaging (if needed):

 – Venography, MRvenography if considering interventions

📍UK Epidemiology:

 – Affects up to 20–50% of patients post-DVT

 – Significant causeof long-term morbidity

💊Management:

• Conservative First-Line:

 – Compression therapy (graduated stockings)

 – Leg elevation, regularwalking

 – Weight loss,optimise cardiovascular risk factors

• Important Guideline Note:

 – Stockings are not routinely recommended for preventingPTS post-DVT

 – But they are recommended for treatment once PTS isdiagnosed

• Severe Cases:

 – Endovascular stenting or angioplasty for obstruction

 – Rarely: open veinsurgery

 – Ulcer management with dedicated wound careservices

📈Prognosis:

• Varies widely —early recognition + compression helps symptom control

• Often chronic, butmanageable with consistent therapy

• In severe cases,can impair mobility and quality of life

• Ulcers can becomerecurrent, infected, or non-healing

⚠️Complications:

• Venous ulcers (persistent, painful, slow toheal)

• Recurrent DVT

• Chronic pain, mobility issues

• Pulmonary embolism if new clots form

• Psychosocial impact due to reduced activity +visible leg changes

📚Memory Aids:

• Think: “Post-DVT→ Persistent Damage”

• Pain + Pigment + Puffiness = classic triad

• Elevation helps → suggests venous cause

• Ultrasound is key for diagnosis

🩸 FREE MSRA PODCAST – Polycythaemia Vera: JAK2, Clots &Core Concepts 🎧

In this haematologydeep dive, we break down everything you need to know about polycythaemia vera (PV) and its differentials.From JAK2 mutations to therapeuticphlebotomy, we cover it all with memory aids and exam-friendly explanations.Whether you're revising for the MSRA or brushing up for clinical practice, thisepisode simplifies it, step by step.

🧠Key Learning Points

📌Definition

Polycythaemia = anincrease in red blood cell mass

• PV = primary polycythaemia, caused by bone marrow overproduction

• Secondarypolycythaemia = due to external signals(e.g. hypoxia, EPO)

• Relativepolycythaemia = plasma volume depletion,not true RBC excess

📌Causes

🔬Primary – JAK2 mutation (95% of PV cases), bone marrowstem cell disorder

🔬Secondary – driven by ↑ erythropoietin:

 – Chronic hypoxia(COPD, OSA, altitude)

 – Renal cellcarcinoma, hepatocellular carcinoma

 – Smoking,testosterone, EPO abuse

🔬Relative – dehydration, diuretics, stress (e.g. Gaisböcksyndrome)

🧠 Mnemonic: HALT – Hypoxia,Abnormal EPO (tumours), Lung disease, Testosterone/EPO

📌Pathophysiology

• PV = JAK2 mutation → bone marrow becomeshypersensitive to EPO → ↑ RBCs

• Thickened blood →increased viscosity → sluggish flow →clot risk

• Often affects RBCs, WBCs & platelets

📌Symptoms

• Headaches,dizziness, visual disturbances

• Pruritus(especially after hot showers)

• Facial plethora(ruddy complexion)

• Splenomegaly →early satiety

• Fatigue

• Thrombotic events(DVT, PE, stroke, MI)

• May beasymptomatic and picked up on FBC

📌Investigations

🔍 FBC: ↑ Hb, ↑ HCT

🔍 JAK2 mutation testing

🔍 Serum EPO: ↓ in PV, ↑ in secondary causes

🔍 ABG (check for hypoxia)

🔍 Ultrasound/CT (if suspect tumour or splenomegaly)

🔍 Bone marrow biopsy if unclear

🔍 Red cell mass study (to confirm true polycythaemiavs relative)

🧠 Mnemonic: JABES – JAK2,ABG, Bone marrow, EPO, Splenic imaging

📌Management

🎯Goals: Reduce clot risk + relieve symptoms

• Venesection (phlebotomy) – keep HCT <45%

• Low-dose aspirin – reduce thrombosis

• Hydroxyurea – for high-risk or older patients

• Interferon – alternative in younger or pregnantpatients

• Treat secondary causes – e.g. smokingcessation, COPD control

• Lifelong haematology follow-up

📌Complications

• Thrombosis – main cause of morbidity andmortality

• Myelofibrosis – scarring of bone marrow

• Acute leukaemia (AML) – in long-term cases

• Haemorrhage – paradoxical bleeding due toplatelet dysfunction

• Cardiovascular disease – due to chronic strain

🎧 Deep Dive: Polycythaemia Vera (PV)
🩸 When the Bone Marrow Doesn’t Know When to Stop...
Fatigue, post-shower itching, ruddy complexion — it might not be stress. It could be Polycythaemia Vera, a chronic myeloproliferative neoplasm. In this concise, high-yield episode, we break PV down into bite-sized, exam-friendly chunks perfect for the MSRA.

🧠 In This Episode:

✅ Definition & Overview
• PV = Clonal overproduction of red cells, often with raised platelets and neutrophils
• Driven by JAK2 V617F mutation (~95%)
• Causes increased blood viscosity and thrombosis risk
• It’s a primary polycythaemia (not secondary to hypoxia or EPO)

✅ Pathophysiology & Aetiology
• JAK2 mutation → constant JAK-STAT activation
• Leads to uncontrolled erythropoiesis
• Progresses to myelofibrosis or rarely AML

✅ Differentials
• Relative polycythaemia: dehydration
• Secondary polycythaemia: COPD, altitude, tumours
• Other MPNs: ET, CML (Philadelphia+)
→ 🔑 Tests:
– EPO: ↓ in PV
– JAK2: present in PV
– O2 sats, imaging, red cell mass studies

✅ Epidemiology
• Rare: ~2/100,000/year (UK)
• Affects mostly 60–70 yrs
• Slight male predominance

✅ Clinical Features
• Fatigue, headache, dizziness
• Pruritus, esp. after warm baths
• Plethora (ruddy face), splenomegaly (75%)
• Thrombosis: DVT, PE, MI, stroke
• Paradoxical bleeding (platelet dysfunction)
• Rarely: Budd-Chiari, erythromelalgia

✅ Investigations
• FBC: ↑ Hb, Hct, WCC, platelets
• JAK2 mutation
• ↓ EPO, ↓ ESR, ↑ uric acid
• Bone marrow biopsy: hypercellular, trilineage growth
• Also: ferritin (low), CXR, abdo US, O2 sats

✅ Management
🎯 Goal: Prevent thrombosis, delay transformation
• Phlebotomy (target Hct < 45%)
• Low-dose aspirin
• Hydroxyurea or interferon-alpha (cytoreduction)
• Ruxolitinib: refractory cases
• Treat CV risk: statins, BP control
• Symptom relief: antihistamines, SSRIs (off-label)
• Gout prophylaxis: allopurinol
• Rare: splenectomy for severe splenomegaly

🔁 Risk Stratification
• Low-risk: phlebotomy + aspirin
• High-risk: add cytoreduction (e.g. hydroxyurea)

✅ Complications
• Thrombosis (stroke, PE, MI)
• Myelofibrosis transformation
• Rarely: AML (<10%)
• Bleeding, gout, splenic infarcts

✅ Prognosis
• Good with treatment
• Median survival: 14–24 years
• Younger, fewer clots = better outlook
• Lifelong monitoring essential

🎧MSRA Podcast:Platelet Transfusion for Active Bleeding – When Every Platelet Counts! 🎧

In this rapidrevision episode, we break down exactly what you need to know about platelet transfusion for active bleeding—acrucial, life-saving intervention every MSRA candidate should understand.Whether you’re prepping for exams or clinical practice, this is your ultimate“need-to-know” guide.

🗝️ Key Learning Points

Definition

• Platelet transfusion = giving concentrated platelets to a patient with active, significant bleeding due to low count or dysfunctional platelets.
• Think: emergency reinforcements for the clotting team!

Causes & Indications

• Thrombocytopenia (low platelets)—from bone marrow failure, chemotherapy, severe infection, aplastic anaemia
• Platelet dysfunction—due to meds (aspirin, clopidogrel), inherited disorders
• Major bleeding—post-surgery, trauma, invasive procedures
• Liver disease or massive transfusion (dilutional coagulopathy)

Risk Groups Mnemonic: BMOCS

• B: Bone marrow failure/disorders (leukaemia, aplastic anaemia)
• M: Medications (chemo, antiplatelet drugs)
• O: Organ failure (especially liver)
• C: Chemotherapy patients
• S: Surgery or severe trauma

How It Works

• Restores platelet numbers and function
• New platelets rush to injury: adhesion → aggregation → plug formation
• Strengthens the clot, stops bleeding

Who Needs It? (BEACH-P mnemonic)

• B: Bleeding uncontrolled (active)
• E: Easy bruising
• A: Appearance of petechiae (small red spots)
• C: Cuts that bleed longer than normal
• H: Heavy periods (in women)
• P: Post-procedure bleeding

Investigations

• Full blood count (FBC) for platelet count
• Peripheral blood smear for cell appearance
• Coagulation studies (PT, aPTT), platelet function tests
• Always investigate and treat underlying cause!

Management

• Urgent assessment: Recognise severity, get FBC/coags
• Follow national guidelines (UK Blood Services, NICE): ensure ABO compatibility, calculate correct dose, close monitoring
• Administer IV platelet transfusion—promptly if actively bleeding!
• Monitor for reactions during and after

Complications

• Transfusion reactions: allergic or febrile non-haemolytic
• Transfusion-related acute lung injury (TRALI)
• Volume overload (TACO)
• Alloimmunisation (rare with modern screening)
• Extremely rare infection transmission

Prognosis

• Depends on underlying cause
• Early, appropriate transfusion = better bleeding control, reduced risk of shock/organ failure
• Ongoing monitoring and treating the root problem is essential

🎧PNH – ParoxysmalNocturnal Haemoglobinuria Deep Dive for MSRA

Ever wondered whathappens when red blood cells are attacked by your own immune system? In thisepisode, we unravel the rare and fascinating condition PNH, focusing on what it is, why ithappens, how to recognise it, and how it's treated. This is yourhigh-yield revision companion for MSRAhaematology!

🔍Definition

PNH is a rare acquired haematological disorder caused bya mutation in the PIGA gene, leading to intravascular haemolysis, bone marrow failure, and increased thrombosis risk.

🧠Mnemonic:

PNH = Peeing Nighttime Haemoglobin

🧬Pathophysiology

🧪PIGA mutation → ↓ GPI-anchored proteins (CD55, CD59)

⚔️ Loss of protection from complement system → red cell lysis

⚠️ Platelets also affected → ↑ thrombosis risk

🧠Mnemonic:

Flow so low, CD55 & CD59 won’t show!

💉Key Features

• 🔴 Dark urine (especially in the morning – hemoglobinuria)

• 😩 Fatigue, anaemia, shortness of breath

• ⚡ Abdominal pain, clot risk (e.g. Budd-Chiari syndrome)

• 📉 Pancytopenia or marrow failure in some cases

🧪Investigations

✔️Flow cytometry (Gold standard – detects absent CD55/CD59)

✔️ FBC (anaemia, low WBC/platelets)

✔️ LDH ↑, haptoglobin ↓

✔️ Urine dip – blood without red cells

✔️ Bone marrow biopsy (if failure suspected)

✔️ Imaging – for complications (e.g. hepatic veinthrombosis)

🔬Differentials

• Autoimmunehaemolytic anaemia

• Thromboticmicroangiopathies (TTP, HUS)

• Aplastic anaemia

• Myelodysplasticsyndrome

📊Epidemiology

• 🧬 Acquired, not inherited

• 📈 ~1–10 cases per million

• 👩‍⚕️ Often in young adults, both sexes

• May arisesecondary to aplastic anaemia

💊Management

✅Eculizumab (anti-C5 monoclonal antibody) – cornerstonetherapy

✅Vaccination against Neisseria meningitidis before eculizumab

✅Anticoagulation – for thrombosis prevention/treatment

✅Blood transfusions – supportive

✅Stem cell transplant – curative option in select cases

✅ Consider steroids (e.g.prednisolone) for temporary control

🧠Mnemonic:

Eculizumab = End Complement Lysis

⚠️Complications

• 🔒 Thrombosis (e.g. Budd-Chiari, PE, cerebral vein thrombosis)

• 🔄 Bone marrow failure

• 🧠 Neurological events

• 🚽 Renal dysfunction

• 🫁 Pulmonary hypertension

• ⚠️ Death from thromboembolism if untreated

🔮Prognosis

• 🌟 Improved with complement inhibitors like eculizumab

• ⚖️Varies based on clone size & severity

• 🧬 Some spontaneous remission possible

• 💀 Thrombosis is leading cause of mortality

🎧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”

🩸 FREE MSRA PODCAST – Normocytic Anaemia: Normal Size,Hidden Problems 🎧

Inthis revision-packed episode, we unpack Normocytic Anaemia— a common but often misunderstood form of anaemia where red cells are normal in size, but there's still an issue. You'll learn toclassify, investigate, and manage it effectively, and master the high-yieldMSRA knowledge you need. Perfect for your haematology revision. 🧠📚

🧠Key Learning Points

📌Definition

Normocytic anaemia =anaemia with a normal mean corpuscular volume(MCV) (typically 80–100 fL).

Red cells are normal-sized, but there's not enough of them, or they're not functioning properly.

📝 Mnemonic: "Normal size – problem elsewhere."

📌Causes (use CHBNHA mnemonic)

C – Chronic disease (e.g. CKD, chronicinflammation)

H – Haemolysis (increased destruction)

B – Bone marrow failure (e.g. aplastic anaemia,myelofibrosis)

N – Nutritional deficiencies (early-stageiron/B12/folate deficiency)

H – Hormonal issues (e.g. hypothyroidism)

A – Acute blood loss (e.g. trauma, GI bleed)

📌Risk Factors

🔹 Older age

🔹 Chronic illness (CKD, autoimmune disease, cancer)

🔹 Family history of blood disorders

🔹 Certain medications or toxins

🔹 Ethnic predispositions to haemoglobinopathies

📌Pathophysiology

• Either reduced red cell production (e.g. bone marrowsuppression, chronic disease)

• Or increased red cell destruction (e.g.haemolysis)

• Or shortened lifespan of red cells without achange in size

• May be an earlyphase of other types of anaemia

📌Symptoms

• General anaemiasymptoms:

 – Fatigue, pallor,weakness, dizziness

 – SOB, headaches,cold extremities

 – Palpitations orchest pain in severe cases

• Often asymptomatic until moderate or severe

📌Investigations

🔬FBC – low Hb, normal MCV

🔬Reticulocyte count – to assess marrow response

🔬Blood film – rule out haemolysis or abnormal cells

🔬Iron studies, B12,folate – rule out masked deficiencies

🔬CRP/ESR – assess for chronic inflammation

🔬Renal & thyroidfunction

🔬Bone marrow biopsy – if diagnosis unclear

🧠 Mnemonic: "FIRM BBT"– FBC, Iron/B12/Folate, Reticulocytes, Marrow, Blood film, Biochemistry,Thyroid

📌DifferentialDiagnosis

• Early iron deficiency

• Mixed nutritional deficiencies

• Chronic kidney disease

• Autoimmune disease or malignancy

• Haemolytic anaemia

• Hypothyroidism

• Aplastic anaemia or myelofibrosis

📌Management

🎯Target the underlyingcause:

• CKD →EPO-stimulating agents

• Inflammatorydisease → treat the source

• Nutritional →replace iron, B12, folate

• Hypothyroidism →thyroxine

💉Transfusion may be needed for severe symptomatic anaemia

🛡️Monitor forcomplications – esp. in chronicdisease states

📌Prognosis &Complications

• Highly variable, depending on the cause

• Good if cause isreversible (e.g. acute blood loss, treatable deficiency)

• Poorer outlookwith irreversible marrow failure or CKD

• If untreated:fatigue, reduced QoL, cardiac strain or heart failure in severe cases

🎧 Deep Dive: Non-Hodgkin’s Lymphoma (NHL)
🩸 A Diverse, Complex Group of Lymphatic Cancers — Made Clear.
Feeling overwhelmed by Non-Hodgkin’s Lymphoma? This episode simplifies a massive topic into a clear, high-yield revision guide for the MSRA exam. We walk you through types, symptoms, staging, investigations, and management — all in under 20 minutes.

🧠 What You’ll Learn

✅ Definition
• NHL = a group of lymphoproliferative cancers affecting B- or T-cells
• Can be indolent (low-grade) or aggressive (high-grade)
• May involve lymph nodes or extranodal sites (GI, CNS, skin)

✅ Classification
• By cell type: B-cell or T-cell
• High-grade B-cell: DLBCL, Burkitt's
• Low-grade B-cell: Follicular, MALT, Waldenström's
• T-cell: Mycosis fungoides, EATL

✅ Causes & Risk Factors
• Genetic mutations, immune dysfunction
• Viruses: EBV, HIV, HTLV-1, Hep C
• Infections: H. pylori (MALT)
• Immunosuppression, autoimmune disease
• Chemical exposure (e.g. pesticides)

✅ Pathophysiology
• Clonal expansion of lymphocytes
• Infiltrates lymph nodes, marrow, organs
• Causes mass effect and immunosuppression

✅ Differentials
• Hodgkin’s lymphoma
• Leukaemias
• Metastatic cancer
• Infective/reactive nodes
• Autoimmune (e.g. SLE)

✅ Epidemiology
• 6th most common UK cancer (~13% of new diagnoses)
• Risk ↑ with age; peak >75
• DLBCL = most common (30–40%)

✅ Clinical Features
• Painless lymphadenopathy (neck, axilla, groin)
• B symptoms: fever, night sweats, weight loss
• Splenomegaly, fatigue, cytopenias
• Extranodal signs: GI obstruction, CNS features, testicular/skin lesions

✅ Investigations 🧪
• FBC: Neutropenia, Anaemia, Thrombocytopenia (→ NAT)
• LFTs, U&Es
• Biopsy (excisional = gold standard)
• Imaging: CT, PET-CT, MRI (if CNS)
• Bone marrow ± lumbar puncture
• Virology screen: HIV, HTLV-1, Hep C

💡 Memory Tips
• NAT = classic blood picture
• DD = Biopsy = definitive diagnosis
• SS = CT to "see spread"
• B symptoms = “Body-wide signs”

✅ Staging – Ann Arbor System
• I = Single site
• II = ≥2 regions, same diaphragm side
• III = Both sides
• IV = Extranodal spread
• A = no B symptoms, B = systemic, E = extranodal site

✅ Management Options
• 🧘 Watchful waiting – asymptomatic low-grade
• 💉 R-CHOP – standard for DLBCL
• 💡 Radiotherapy – early or bulky disease
• 🧬 CAR T-cell therapy – relapsed B-cell NHL
• 🧪 Monoclonal antibodies (e.g. rituximab)
• 💊 Supportive: vaccines, G-CSF, antimicrobials
• 🔁 Stem cell transplant for refractory disease

✅ Prognosis & Complications
• Low-grade: indolent but incurable
• High-grade: potentially curable
• Risks:
 – Tumour lysis syndrome
 – Neutropenic sepsis
 – Bone marrow failure (NAT)
 – Organ compression/obstruction
 – Treatment toxicities

🎧MSRA Podcast:Neutropenic Sepsis – When Every Minute Counts! 🎧

Ever heard thephrase “Time is neutrophils”? Neutropenic sepsis is one of the true medical emergencies—and a must-know for yourMSRA, acute medicine, and real-life practice. In this episode, we cut the jargon and give you a step-by-step,no-fluff breakdown of what really matters.

🗝️ Key Learning Points

Definition

• Neutropenic sepsis = sepsis in a patient with neutropenia (neutrophil count < 0.5 x 10⁹/L, or < 500/μL).
• Most often seen 7–14 days after chemotherapy. “Low cells + fever = act fast!”

Criteria

• Fever ≥ 38.3°C OR other clinical features of sepsis.
• Neutrophil count < 0.5 x 10⁹/L (500/μL).

Causes

• Chemotherapy (biggest cause)
• Radiation therapy
• Bone marrow disorders
• Central lines (catheter infections)
• Underlying malignancy (especially haematological)

Risk Factors Mnemonic:

“Chemo Problems Lead to Infection Catastrophe”

• C: Chemo/radiation
• P: Prolonged neutropenia
• L: Low neutrophil count
• I: In-dwelling lines (central venous catheter)
• C: Cancer (especially blood cancers)
• Plus: previous infections, comorbidities

Pathophysiology

• No neutrophils = no first responders.
• Even “normal” bugs or patient’s own gut flora can cause rapid, overwhelming infection and sepsis.
• Widespread infection → rapid deterioration → shock/multi-organ failure.

Symptoms & Signs

• Fever (most common, can be the only sign)
• Chills, rigors, sweats
• Tachycardia, hypotension, tachypnoea
• Profound weakness, confusion, altered mental status
• Sometimes localising signs: line infection, cough (pneumonia), cellulitis

Diagnosis

• FBC with differential (confirm neutropenia)
• Blood cultures (peripheral + line if present)
• Other cultures: urine, sputum as indicated
• Imaging: CXR, CT if needed to localise infection
• Assess severity: lactate, kidney function, etc.

Management (Core MSRA Emergency!)

• ABCs: Antibiotics Broad-spectrum—Currently!
  (Start IV antibiotics within 1 hour, do not wait for bloods or cultures)
• Hospital admission and supportive care (IV fluids, oxygen)
• Monitor for and treat complications: septic shock, organ dysfunction
• Tailor antibiotics when culture results return
• Consider GCSF in select, specialist-assessed cases

If fever doesn’t settle in 48h:

• Broaden antibiotics (e.g. add vancomycin)
• If >4–6 days and no source, consider fungal infection

Complications

• Septic shock
• Multi-organ failure (renal, respiratory, cardiac)
• Disseminated infection/abscesses
• High mortality without rapid treatment

Prognosis

• Early recognition and prompt antibiotics = better outcomes
• Delay increases risk of death—never wait for labs if clinical suspicion is high
