🎧 MSRA Podcast: Vitamin B12 Deficiency – Blood, Brain & Baffling Symptoms
Welcome to another high-yield MSRA Deep Dive! This episode unpacks Vitamin B12 deficiency — from fatigue and glossitis to neurological confusion and cord demyelination. Whether you're revising or recognising it in practice, this guide makes it memorable.

🧠 What You’ll Learn:

✅ Definition
• B12 deficiency = low levels of vitamin B12 → affects DNA synthesis, red blood cell production, and nerve health
• Leads to megaloblastic anaemia and neurological symptoms

✅ Common Causes
• Pernicious anaemia (PA) – ↓ intrinsic factor from autoimmune gastritis
• Vegan/vegetarian diets without B12 supplements
• Malabsorption – Crohn’s, coeliac, ileal resection
• Meds – PPIs, metformin
• Rare genetic B12 transport issues

📌 Mnemonic: AVG-PGLF
A – Age (elderly)
V – Vegan diet
G – GI disorders
P – Pernicious anaemia
G – Gastric surgery
L – Long-term meds
F – Family history

🧬 Pathophysiology
• B12 needed for DNA synthesis + myelin
• Deficiency → impaired cell division (anaemia)
• Affects posterior columns → proprioception loss, paraesthesia

🔍 Differential Diagnoses
• Folate deficiency – similar blood picture, no neuro signs
• Alcohol misuse, liver disease, hypothyroidism – macrocytosis
• MS, diabetic neuropathy – neuro overlap

📊 Epidemiology (UK)
• PA: ~1 in 1000 (esp. women aged 40–70)
• B12 deficiency: ~6% (<60 yrs), ~20% (>60 yrs)
• Vegan deficiency risk: ~11%

⚠️ Clinical Features – Mnemonic: 5Ps + Neuro CCC-H
Pallor
Paraesthesia
Peripheral neuropathy
Psychiatric symptoms
Proprioception loss

• Confusion, Coordination issues, Cognitive decline, Heaviness in legs

Other signs: Glossitis, fatigue, breathlessness

🧪 Investigations
• Serum B12 (may miss borderline cases)
• Methylmalonic acid, Homocysteine – rise in deficiency
• FBC: macrocytic anaemia, hypersegmented neutrophils
• Anti-intrinsic factor, anti-parietal cell antibodies
• Exclude: Folate deficiency, liver disease, hypothyroidism
• Gastroscopy in PA (↑ gastric cancer risk)

💉 Management
• Hydroxocobalamin IM (NICE):
 – No neuro signs: 1mg IM 3×/week × 2wks → then 1mg IM every 3 months
 – With neuro: 1mg IM on alternate days until improvement
• Oral B12: if purely dietary and no malabsorption
• Always treat B12 before folate to avoid masking deficiency
• Address cause: e.g. diet, meds, gut disorder
• Monitor response via FBC + symptom resolution

📈 Prognosis
• Good if diagnosed early
• Neurological damage can become permanent if treatment is delayed
• PA = lifelong B12 replacement + cancer screening

🛑 Complications if Untreated
• Subacute combined degeneration of spinal cord
• Irreversible neuropathy, gait disturbance
• Severe anaemia → heart failure
• NTDs in pregnancy, infertility
• ↑ Homocysteine → possible CVD link
• Gastric cancer risk in PA

🎧Deep Dive: VonWillebrand’s Disease (VWD) – MSRA High-Yield Haematology

Ever wonder why somepeople bruise easily or get nosebleeds that just don’t stop? It could be Von Willebrand’s Disease – the most common inherited bleeding disorder. Inthis episode, we break it all down clearly, efficiently, and with exam-focused tips to help you master it for theMSRA and clinical life.

🧬What is VonWillebrand’s Disease (VWD)?

VWD is a genetic bleeding disorder caused by adeficiency or dysfunction of von Willebrandfactor (VWF) – a protein vital for:

1️⃣Platelet adhesion at injury sites

2️⃣Protecting factorVIII from degradation

💡Analogy: VWF is the glue forplatelets and thebodyguard for factor VIII.

📊VWD Types – MemoryHooks Included!

🔹 Type 1 (Volume Down):

• Most common(60–80%)

• Quantitativedefect – ↓ amount of VWF

🔹 Type 2 (Function Fails):

• Qualitative defect– VWF doesn’t work right

• Subtypes:

 • 2A – Absentmultimers

 • 2B – Bindsspontaneously (risk of thrombocytopenia)

 • 2M – Misfitbinding

 • 2N – No factorVIII binding (mimics mild haemophilia A)

🔹 Type 3 (Totally Absent):

• Severe, almost no VWF

• Autosomalrecessive

🧠Mnemonic Recap:

• 1 = Volume down

• 2 = Function fails

  • 2A = Absentmultimers

  • 2B = Bindsspontaneously

  • 2M = Misfitbinding

  • 2N = No FVIIIbinding

• 3 = Totally absent

🔍Symptoms & Signs

• Easy bruising

• Frequent/prolongednosebleeds (epistaxis)

• Menorrhagia in women

• Prolonged bleedingpost-dental work or minor injuries

• GI bleeding (lesscommon)

• Severe: jointbleeds (type 3)

🧠 Think: Platelet-type bleeding + factor VIII impact

🧪Diagnosis – What toOrder

1. VWF antigen – measures amount
2. VWF activity – ristocetin cofactor assay
3. Factor VIII level – often ↓
4. APTT – may be prolonged
5. Genetic testing – confirms type/subtype
6. Platelet function tests – rule out other disorders
7. VWF multimer analysis – for type 2 classification

👩‍⚕️Management Summary –Know the Strategy

🩸 Mild Bleeds

• Tranexamic acid – stabilises clots

💉 Desmopressin (DDAVP)

• Triggers VWF +FVIII release from endothelium

• Effective for type 1

• ⚠️ Avoid in type 2B and type 3

• Trial dose oftenneeded

🧬 Factor Replacement Therapy

• Plasma-derived orrecombinant VWF concentrates

• Essential in type 3, major bleeds, or surgery

💊 Hormonal Options (for Menorrhagia)

• COCP, Mirena IUS,or cyclic progesterone

🩹 General Measures

• Avoid NSAIDs

• Local pressure,tranexamic mouthwash

• Plansurgery/delivery with haematology input

📈Epidemiology &Risk

• Up to 1% prevalence – mostcommon inherited bleeding disorder

• Often undiagnosedor mild

• Type O blood =lower baseline VWF

• Women more oftendiagnosed due to menorrhagia

⚠️Complications (If untreated or undiagnosed):

• Iron-deficiencyanaemia

• Arthropathy (rare,from joint bleeds)

• Peripartumhaemorrhage

• Life-threateningbleeding in major trauma/surgery

✅BUT – with diagnosis + personalised management, most people live full, healthylives.

🎙️ Deep Dive: Multiple Myeloma – The Plasma Cell Puzzle Unlocked
🧪 High-yield revision for the MSRA and clinical practice

Welcome back to The Deep Dive, where we break down big topics into memorable, exam-focused insights. Today’s topic? Multiple Myeloma – the second most common blood cancer in the UK and a must-know for the MSRA. 🧠

In this episode, we’ll walk you through definition, diagnosis, key features, investigations, treatment, and prognosis — all in one concise, efficient session.

🧩 What is Multiple Myeloma?
• A cancer of plasma cells in bone marrow
• Produces abnormal monoclonal proteins (M-protein / paraprotein)
• Causes damage to bones, kidneys, immune system, and blood cells
• Often preceded by MGUS or Smouldering Myeloma

💡 CRAB Features – Core Symptoms
Use this in MSRA and clinical diagnosis:
C – Calcium (hypercalcaemia → thirst, confusion)
R – Renal dysfunction (↑ creatinine, Bence-Jones proteins)
A – Anaemia (fatigue, breathlessness)
B – Bone lesions (pain, fractures, lytic lesions)

🧠 Tip:
MGUS → Smouldering Myeloma → Active Myeloma

📊 Epidemiology & Risk Factors
• Incidence: ~4.5–6 per 100,000/year
• Median age: ~72
• More common in men and Afro-Caribbean patients
• Risk factors: Age, sex, obesity, radiation, benzene, family history

🩺 Key Investigations
✅ Bloods: FBC, U&Es, calcium, albumin, ESR/CRP
✅ Protein tests:
 • Serum protein electrophoresis (SPEP)
 • Serum free light chain assay
 • Urine protein electrophoresis (UPEP)
 • Immunofixation
✅ Bone marrow biopsy → ≥10% clonal plasma cells
✅ Imaging: Whole-body MRI or low-dose CT
✅ FISH genetic analysis
✅ β2-microglobulin & albumin → staging

🧬 Diagnosis (IMWG Criteria)
→ ≥10% clonal plasma cells OR biopsy-proven plasmacytoma
PLUS ≥1 of the following:
• CRAB criteria
• Plasma cells ≥60%
• FLC ratio ≥100
• MRI focal lesion ≥1

💉 Management Essentials

1. Induction: Bortezomib + dexamethasone ± immunomodulator

2. Stem cell transplant (if eligible)

3. Maintenance: Lenalidomide (post-transplant)

4. Non-transplant regimens: Thalidomide, Lenalidomide, Bortezomib

5. Relapse/refractory: Daratumumab, pomalidomide, 2nd transplant, etc.

🛡️ Supportive Care
• Bisphosphonates → reduce fractures & calcium
• Pain relief → opioids, radiotherapy, nerve meds
• Infection prevention → vaccines, IVIG, prophylaxis
• Thromboprophylaxis → esp. with lenalidomide
• Erythropoietin → anaemia
• Spinal stabilisation if needed

📉 Complications Recap
• Fractures, cord compression
• Renal failure
• Infections
• Anaemia
• Hypercalcaemia
• AL amyloidosis
• Hyperviscosity
• Neuropathy

📈 Prognosis
• Median survival: 2–10+ years
• 10-year survival: ~29% in England
• Better with early-stage, low-risk genetics, good treatment response
• Future outlook improving with CAR-T, bispecifics, and novel therapies

🎙️MSRA Podcast: FolicAcid Deficiency – The B9 Breakdown You’ll Remember! 🎙️

Join us as we cutthrough the confusion and get crystal clear on folicacid deficiency—the essential B vitamin you really can’t ignore, especially in pregnancy, chronic disease,and rapid growth. Here’s your quick, punchy, and memorable revision hit!

🗝️ Key Learning Points

Definition

• Folic acid (Vitamin B9) deficiency means low levels of folate, which is vital for DNA synthesis, healthy red blood cell production, and nervous system health.
• Most important consequence? Megaloblastic (macrocytic) anaemia and neural tube defects in pregnancy.

Sources & Memory Tip

• Colorful foods: leafy greens, broccoli, beans, peas, brown rice, fortified cereals, oranges, bananas.
• Memory aid: Think “FOLIAGE for FOLATE”.

Causes (Mnemonic: DAMN)

• Diet: Poor intake, unbalanced diet, alcoholism.
• Absorption: Malabsorption (e.g. coeliac disease, Crohn’s), GI surgery.
• Medications: Anti-folates (methotrexate, trimethoprim), phenytoin.
• Need: Increased demand (pregnancy, rapid growth, cancer, haemolytic anaemia).

At-Risk Groups

• Pregnant women (increased needs)
• Older adults, alcoholics
• People with GI disorders or on chronic anti-folate meds

Pathophysiology

• Folate = DNA factory fuel: Deficiency disrupts cell division—especially in the bone marrow, leading to big, fragile red cells (megaloblastic anaemia).
• Also raises homocysteine (↑ cardiovascular risk) and impairs fetal neural tube development.

Symptoms (Mnemonic: FATIGUE)

• Fatigue, Anaemia, Tongue (glossitis), Irritability, Gut (mild GI upset), Unwell (general), Easy breathlessness/pallor

Investigations

• Full blood count (FBC): Macrocytic anaemia
• Blood film: Macrocytes, hypersegmented neutrophils
• Serum folate & B12 levels (always check both!)
• Red cell folate: Best for long-term status
• Additional: Underlying cause work-up (coeliac screen, LFTs, TFTs)

Key Differential

• Vitamin B12 deficiency (ALWAYS exclude this before treating with folic acid alone to avoid irreversible neurological damage)

Management

• Oral folic acid: 5mg daily for 4 months (higher if malabsorption)
• Address underlying cause: e.g. treat coeliac disease, diet improvement, alcohol support
• Prevention:
• 400 micrograms daily for all women planning pregnancy and during the first 12 weeks
• 5mg daily if high risk (previous NTD, diabetes, anti-epileptics)
• Diet advice: more leafy greens, beans, fortified cereals

Complications

• Untreated: Severe anaemia, heart failure, mild neuropathy, ↑ infection risk
• Pregnancy: Neural tube defects (e.g. spina bifida) if not supplemented

Prognosis

• Excellent if recognised and treated early. Most symptoms resolve; complications preventable.

🎧 Thrombophilia – Loving Thrombosis? Understanding Clotting Risk
🧬🩸 When the body's clotting system goes rogue.
Struggling to memorise conditions like Factor V Leiden or antiphospholipid syndrome? This high-yield episode makes thrombophilia clear, concise, and exam-ready for the MSRA.

🧠 What You’ll Learn:

✅ Definition
• Tendency to form abnormal clots due to a pro-thrombotic imbalance
• Think: “Loving Thrombosis”

✅ Types
🔹 Inherited:
• Factor V Leiden (most common)
• Prothrombin gene mutation
• Protein C/S, Antithrombin deficiency
🔹 Acquired:
• APS, pregnancy, HRT/OCP, cancer, immobility, autoimmune disease

✅ Red Flags & Risks
• Unprovoked VTE, especially <40
• Recurrent miscarriages
• Strong family history
• Smoking, obesity, oestrogen use
• Clots in odd sites (portal/cerebral veins)

✅ Pathophysiology
• Imbalance in coagulation cascade
• Leads to DVT, PE, stroke, or unusual thrombi
• Can involve clotting proteins, endothelium, and platelets

✅ Differentials
• APS, cancer, surgery, trauma
• Autoimmune diseases (e.g. SLE)
• Natural anticoagulant deficiencies

✅ Epidemiology
• ~1–5% of UK population
• Factor V Leiden most common inherited form

🩺 Clinical Features
• Classic: DVT, PE
• Unusual: cerebral, portal, mesenteric clots
• Pregnancy loss
• Warfarin-induced skin necrosis (Protein C/S deficiency)

🔬 Investigations
• History: personal + family
• FBC, PT, APTT, ESR/CRP, ANA
• Clotting panel: Factor V Leiden, Prothrombin gene, Protein C/S, Antithrombin
• APS screen: lupus anticoagulant, anticardiolipin, β2-GP1
⚠️ Avoid testing during acute clot or while on anticoagulants

📍 When to Test (BCSH):
• Unprovoked VTE in pregnancy/young age
• Recurrent fetal loss
• Severe warfarin skin necrosis
• Neonatal purpura fulminans
❌ Not for routine VTE or asymptomatic relatives

💊 Management Principles
🎯 Tailored to type & risk
• Anticoagulation: DOACs, warfarin, LMWH
• Lifestyle: stop smoking, manage weight, stay active
• Avoid oestrogen-containing meds in high-risk groups
• Pre-pregnancy counselling
• Short-term prophylaxis (surgery, long travel)
• Long-term anticoagulation if >1 unprovoked VTE

🧠 Mnemonics
“Loving Thrombosis” = Thrombophilia
CLOTS =
 C – Clot history
 L – Loss (pregnancy)
 O – Odd clot sites
 T – Thrombosis unprovoked
 S – Skin necrosis (warfarin)

📈 Prognosis
• Variable – depends on type and risk factors
• Most patients do well with appropriate care
• Risks: PE, stroke, pregnancy loss, post-thrombotic syndrome

🎧Deep Dive: TumourLysis Syndrome (TLS) – MSRA Emergency Focus

Welcome to your rapid-fire revision on Tumour Lysis Syndrome (TLS) – a life-threateningoncological emergency you absolutely need to master for the MSRA and real-world clinical practice.

⚠️What is Tumour LysisSyndrome (TLS)?

TLS occurs when alarge number of cancer cells lyse (break down) rapidly – typically afterstarting treatment – flooding the bloodstream with intracellular contents andtriggering metabolic chaos.

🧪Core BiochemicalHallmarks – Think PUKH

• Phosphate ↑

• Uric acid ↑

• K (Potassium) ↑

• Hypocalcaemia (Calcium ↓)

🧠Mnemonic: PUKH – phosphate, urate, potassium high, hypocalcaemia

🔬Causes & RiskFactors

TLS is most common in haematological cancers like:

• Acute leukaemias

• Burkitt lymphoma

• High-gradenon-Hodgkin lymphoma

💣Triggers

• Chemotherapy

• Radiotherapy

• Steroids(sometimes)

🚩High-Risk Patients

• High tumour burden

• High proliferationrate

• Pre-existing renalimpairment

• Dehydration

• Elevated baselineuric acid

• Children (morevulnerable)

🧬Pathophysiology in 3Steps

1. Lysis of tumour cells
2. Release of potassium, phosphate, urate
3. Kidney overwhelmed → metabolic derangement & AKI

🎯Key Effects

• Hyperkalaemia → arrhythmias

• Hyperphosphataemia + hypocalcaemia → tetany,seizures

• Hyperuricaemia → uric acid nephropathy

• Metabolic acidosis → worsens organ function

📊Cairo-Bishop Criteria

1. Laboratory TLS – Based on abnormal blood values
2. Clinical TLS – Lab abnormalities + clinical signs (AKI, seizures, arrhythmias)

🔍Symptoms to Watch For

• Fatigue, nausea,vomiting

• Muscle cramps,tetany

• ↓ Urine output(AKI)

• Confusion orseizures

• Cardiacarrhythmias

🧪Key Investigations

• U&Es, calcium,phosphate, urate, LDH

• Creatinine &eGFR

• ECG (arrhythmiarisk)

• Strict fluidbalance

• Imaging (renalultrasound or CT if AKI unclear)

🛡️Management – Think inPhases

🔹 Prevention is Key:

→ Assess risk before chemotherapy

• Low risk – Monitor

• Intermediate risk – IV fluids + oral allopurinol

• High risk – IV fluids + IV rasburicase (not allopurinol)

💡 Mnemonic: ALLOral / RAS-IV

→ Allopurinol = oral, Rasburicase = IV

🔹 Treatment of Established TLS:

• Aggressive IV fluids (no potassium!)

• Rasburicase daily

• IV calcium gluconate – for symptomatichypocalcaemia only

• Correct electrolytes (avoid worsening CaPO₄deposits)

• Dialysis – if AKI/severe derangement

• Continuous cardiac monitoring

📵Do not use urinaryalkalinisation – no longer recommended

📉Prognosis

• Excellent ifrecognised early and managed aggressively

• Poor if diagnosisis delayed or complications develop

• Mortality oftendue to AKI or arrhythmias

💣Complications

• Acute kidneyinjury (may require dialysis)

• Life-threatening hyperkalaemia

• Hypocalcaemia →seizures/tetany

• Calcium-phosphatedeposits

• Metabolic acidosis

• Multi-organfailure

🧠Key Takeaway

TLS =a biochemical time bomb 💣 in cancer patients.

PUKH + Prevention = Survival.

Identify high-riskpatients, initiate prophylaxis early, and act fast at the first sign oftrouble.

🩸 FREE MSRA PODCAST – Thrombocytosis: Clot Risks, JAK2& Clinical Clues 🎧

This episode breaksdown everything you need to know about thrombocytosisfor the MSRA exam – from essentialthrombocythaemia (ET) and JAK2 mutationsto secondary/reactive causes like infections, inflammation, and irondeficiency. If you've ever seen a high platelet count and thought, “What now?”– this one’s for you.

🧠Key Learning Points

📌Definition

Thrombocytosis = platelet count >450 x10⁹/L

• Primary = bone marrow disorder (essentialthrombocythaemia)

• Secondary = reaction to another condition(infection, inflammation)

• Relative = due to plasma volume loss(dehydration)

📌Causes

🔬PrimaryThrombocytosis (ET)

• JAK2 V617F mutation (~50% of ET cases)

• Bone marrowoverproduction of platelets

• Megakaryocytehyperplasia seen on biopsy

🔬Secondary (Reactive)Thrombocytosis

• Infection(bacterial, viral, parasitic)

• Inflammation(e.g., IBD, rheumatoid arthritis)

• Iron deficiencyanaemia

• Post-splenectomy

• Trauma, surgery,bleeding

• Cancer (lung,renal, ovarian, breast)

• Cytokine therapy,rebound after chemo

🧠 Mnemonic: I-CLIP IT –Infection, Cancer, Loss (blood), Inflammation, Post-op, Iron deficiency, Trauma

📌Pathophysiology

• Primary: Autonomous megakaryocyte proliferation→ ↑ platelets ± impaired function → thrombosis or paradoxical bleeding

• Secondary: Cytokine-driven response tophysiological stress → ↑ platelet production

• Platelet functionis typically preserved in secondary causes

📌Symptoms

• Often asymptomatic(especially if mild)

• ET symptoms:

 – Headaches,dizziness, blurred vision

 – Burning pain inhands/feet (erythromelalgia)

 – Paresthesia,fatigue, visual changes

 – Thrombotic events(DVT, PE, stroke)

 – Bleeding (esp. GItract)

• Pregnancycomplications: ↑ miscarriage risk, placental issues

📌Clinical Signs

• Splenomegaly (upto 50% in ET)

• Hepatomegaly (lesscommon)

• Otherwise oftenunremarkable

• Secondarythrombocytosis signs depend on underlying cause

📌Investigations

🔍 Full Blood Count: Persistent platelets >450

🔍 JAK2, MPL, CALR mutation testing

🔍 Inflammatory markers: CRP, ESR

🔍 Iron studies, Ferritin

🔍 Bone marrow biopsy: ET diagnosis, megakaryocytehyperplasia

🔍 Imaging: rule out malignancy or inflammation

🔍 Exclude secondary causes via thorough history +labs

📌Management

🎯PrimaryThrombocytosis (ET)

• Low-dose aspirin – reduce thrombotic risk

• Cytoreductive therapy:

 – Hydroxyurea – first-line

 – Interferon-alpha – for younger/pregnantpatients

 – Anagrelide – alternative

• Plateletpheresis – emergency platelet removalif urgent

• Target: Platelets<450 x10⁹/L

• Pre-operativecytoreduction often needed

🎯SecondaryThrombocytosis

• Treat the underlying cause – e.g., infection,inflammation

• Aspirin – only if high thrombotic risk

• Platelet countoften normalises once trigger is resolved

📌Complications

• Thrombosis – stroke, MI, DVT, PE, mesentericischaemia

• Bleeding – especially when platelets >1,000

• Progression to AML or myelofibrosis (rare inET)

• Pregnancy loss orcomplications in women with ET

🎙️Deep Dive:Splenomegaly — More Than Just an Enlarged Spleen

🔍 A high-yield exploration for your MSRA prep

Welcome to The Deep Dive, your express route to masteringcomplex clinical concepts with clarity. Today, we're shining a spotlight on Splenomegaly — when the spleen sends up a redflag that something bigger is going on.

It'snot just "a big spleen". It's a clinical signthat can reveal infections, blood cancers, liver disease, autoimmune issues,and more. Let’s unpack what it means, how to spot it, and why it absolutelymatters for your MSRA revision and clinical practice. 🧠

🧠In This Episode:

✅Definition & CoreConcept

• Splenomegaly =abnormal enlargement of the spleen

• Remember: thespleen is the immune and recycling depotof the body

• If you can feel it on exam, it’s likely >2x normal size

• It's a sign, not a standalone diagnosis

🦠Causes: The I LICKBUT A TINY INKY MASS Mnemonic

👉 A powerful memory aid for recall:

I – Infections (EBV, TB, malaria,leishmaniasis)

L – Liver disease (cirrhosis, portalhypertension, Budd-Chiari)

B – Blood disorders (leukaemia, lymphoma,polycythaemia vera, myelofibrosis, hemolytic anaemias)

A – Autoimmune (SLE, Felty’s syndrome)

T – Tumours and cysts (metastases, haemangioma,abscess)

I – Infiltrative (amyloidosis, histiocytosis X)

M – Metabolic (Gaucher’s, Niemann-Pick)

O – Other (trauma, pseudocysts, idiopathic)

⚠️Don’t Miss:

• Splenic sequestration crisis in children withsickle cell — medical emergency

• Massive splenomegaly causes = CML,myelofibrosis, leishmaniasis, Gaucher's, tropical splenomegaly

• Spleen shrinkage in late sickle cell(autosplenectomy) = classic exam trick

🧪Investigations

• FBC (look for pancytopenia if hypersplenism)

• LFTs (assess for portal hypertension or liverdisease)

• Ultrasound = 1st line imaging

• CT/MRI = for detailed anatomical assessment

• Further tests =autoimmune screen, blood cultures, bone marrow biopsy, viral panels, dependingon suspected cause

• Caution with splenic biopsy — high bleeding risk

🩺Clinical Features

• LUQ fullness ordiscomfort

• Early satiety(compression of stomach)

• Signs ofcytopenias: fatigue, infections, bleeding

• On palpation:

→ Mass in LUQ

→ Moves with inspiration, towards right iliacfossa

→ Cannot get above it

→ May have a notch

→ Dull to percussion

🛠️Management

🎯Treat the underlyingcause — not the spleen itself

• Infections →antibiotics or antiparasitics

• Haematologicalmalignancy → oncology referral

• Liver disease →manage portal hypertension

• Autoimmune →immunosuppression if needed

• Splenectomy in selected cases: hereditaryspherocytosis, lymphoma staging, refractory hypersplenism

• Vaccinate if spleen is removed ornon-functional:

→ Pneumococcal,Meningococcal, Hib, Influenza annually

→ Considerprophylactic antibiotics post-splenectomy

📊Epidemiology in theUK

• ~39% due to haematological malignancy

• ~18% liver-related

• ~10% infections

• The rest =autoimmune, metabolic, infiltrative, idiopathic

💥Complications

• Hypersplenism → pancytopenia → anaemia,infection risk, bleeding

• Splenic rupture (especially in trauma)

• Variceal bleeding (if linked to portalhypertension)

• Post-splenectomy infections — life-threateningif not vaccinated

🎧MSRA Podcast: SickleCell Anaemia – What Every Clinician Needs to Know! 🎧

Get ready for anengaging, clear, and clinically-focused deep dive into sickle cell anaemia—from genetics to day-to-day management,classic exam features, and essential red flags. Fast, memorable, andexam-ready!

🗝️ Key Learning Points

Definition

• Sickle cell anaemia = inherited blood disorder: abnormal HbS (sickle haemoglobin) causes red cells to become stiff, sickle-shaped, and prone to blocking blood vessels.
• Result: vaso-occlusion (painful crises), chronic anaemia, organ damage.

Causes & Risk Factors

• Autosomal recessive inheritance (both parents carry the HbS gene)
• Most common in those of African, Caribbean, Middle Eastern, and South Asian heritage
• Trait (HbAS) = carrier, usually no symptoms
• Disease (HbSS) = two abnormal genes, classic symptoms

Pathophysiology Mnemonic: SICKLE

• S: S**ubstitution in HBB gene
• I: Impaired red cell flexibility
• C: Chronic haemolysis
• K: Kidney & other organ damage
• L: Low oxygen triggers sickling
• E: Episodes of pain (crises)

Clinical Features

• Painful crises (bones, chest, abdomen)
• Chronic anaemia (fatigue, pallor, jaundice)
• Infection risk (non-functioning spleen)
• Delayed growth (children), leg ulcers, gallstones, priapism
• Complications: stroke, acute chest syndrome, avascular necrosis, kidney/lung/eye problems

Diagnosis

• Newborn screening (heel prick test)
• FBC: anaemia, ↑ reticulocytes
• Blood film: sickle cells, target cells, Howell-Jolly bodies
• Gold standard: haemoglobin electrophoresis / HPLC
• Rapid test: Sickle solubility screen (screening only)
• Genetic testing as needed

Red Flags / When to Seek Urgent Care

• Severe pain not settling
• Fever >38.5°C or signs of infection/sepsis
• Chest pain, breathlessness (acute chest syndrome)
• Neurological symptoms (stroke signs)
• Priapism >2 hours, sudden pallor, splenic enlargement

Management

• Prevention:
• Penicillin V (up to age 5+), vaccinations (pneumococcal, flu, Hib, MenC, etc.)
• Avoid triggers: dehydration, cold, stress, hypoxia
• Acute crises:
• Pain relief (stepwise: paracetamol/NSAIDs → opioids)
• Hydration, oxygen, treat infection if present
• Blood transfusion for severe anaemia/complications
• Disease modification:
• Hydroxyurea (↑ HbF)
• Exchange transfusion (for stroke/acute chest)
• Crizanlizumab for recurrent crises (over 16s, NICE criteria)
• Curative:
• Bone marrow/stem cell transplant (rare, children, matched donor)
• Psychological and social support essential!

Complications – Mnemonic: PAINS

• P: Painful crises / Priapism
• A: Acute chest syndrome / Avascular necrosis
• I: Infections (sepsis, osteomyelitis)
• N: Neurological (stroke, learning difficulties)
• S: Splenic dysfunction, Stunted growth

Prognosis

• Improved with early diagnosis, prophylaxis, comprehensive care
• Median life expectancy in UK: 40–60+ years
• Early intervention, hydroxyurea, and regular specialist review are key to best outcomes
