Q

What is a non haemolytic febrile reaction?

A

Thought to be caused by antibodies reacting with white cell fragments in the blood product and cytokines that have leaked from the blood cell during storage

Q

What is sequestration crisis in sickle cell?

A

Caused by infection with parvovirus
Bone marrow suppression causes a reduced reticulocyte count
Sickle cells cause the spleen to become grossly enlarged > causes abdominal pain
Severe anaemia
Cardiovascular collapse due to loss of effective circulating volume

Q

what is thrombotic crisis in sickle cell?

A

also known as painful crises or vaso-occlusive crises
precipitated by infection, dehydration, deoxygenation (e.g. high altitude)
painful vaso-occlusive crises should be diagnosed clinically - there isn’t one test that can confirm them although tests may be done to exclude other complications
infarcts occur in various organs including the bones (e.g. avascular necrosis of hip, hand-foot syndrome in children, lungs, spleen and brain

25
Howell-Jolly bodies are associated with which condition?
Hyposplenism
26
Alpha thalassaemia - what are the three ways this can present?
A thalassaemia trait HBH disease - microcytic anaemia, splenomegaly, jaundice, growth retardation Severe cases need splenectomy + transfusions Hb barts hydrops fetalis syndrome - severe, almost all die in utero
27
Beta thalassaemia - what are the three ways this can present?
B thalassamia trait - asymptomatic B thalassaemia intermedia - similar picture to HBH disease - require transfusions B thalassaemia major - severe lifelong transfusion dependency, can develop iron overload - requiring iron chelating drugs
28
Sickle disease - how does trait/ sickle cell anaemia and sickle cell disease present?
Sickle cell trait - asymptomatic Sickle cell anaemia - risk of sickle crisis, chronic haemolysis, hypsplenism (due to splenic infarcts) Sickle cell disease - both sickle cell and thallassaemia . Big clot risk.
29
What vaccines should be given to those with sickle cell disease?
Pneumococcous, meningococcus, haemophilus This is because they have hyposplenism due to repeated splenic infarcts. They should also be on lifelong prophylactic penicillin.
30
What investigations are there for haemolysis?
Reticulocyte count Serum unconjugated bilirubin Serum haptoglobins Urinary urobilinogen Blood film Coomb's test - identifies antibodies bound to own red blood cells
31
What might cause a prolonged prothrombin time?
Clotting factor deficiency Warfarin Liver disease Vitamin K deficiency
32
What might cause a prolonged APTT?
Deficiency in clotting factors 8 and 9 Heparin Haemophilia VWB disease Antiphospholipid syndrome
33
Which conditions are included in the hereditary thrombophilias? (cause clots)
Factor V Leiden Antithrombin deficiency Protein C + S deficiency
34
What are the three things you see in antiphospholipid syndrome?
Recurrent thromboses Recurrent miscarriage Mild thrombocytopenia Tx is aspirin/ warfarin - heparin in pregnancy
35
What form of inheritance dose VWF deficiency (bleeding disorder - too bleedy) show? What about haemophilia?
VWF deficiency - Autosomal dominant - men and women Hameophilia - X- linked - men
35
What drug is used for heparin reversal?
Protamine sulphate
36
What conditions cause splenomegaly?
Infection - EBV, malaria Congestion - Hepatic cirrhosis, cardiac failure Haematological - Lymphoma, leukaemia, haemolytic anaemia, ITP, myeloproliferative disorders Inflammatory disease - RA/ SLE
37
What is MGUS - Monoclonal gammopathy of undetermined significance What is myelodysplastic syndrome What is myelofibrosis ?
MGUS - Paraprotein band on bloods but asymptomatic, can go on to develop myeloma. Myelodyasplasia - Mild anaemia or can develop pancytopenia. Myelofibrosis - fibrotic tissue in bone marrow so liver and spleen take over. Anaemia, fevers, gout, splenomegaly. Can progress to AML.
38
What is richter's transformation?
Ritcher's transformation occurs when leukaemia cells enter the lymph node and change into a high-grade, fast-growing non-Hodgkin's lymphoma. Patients often become unwell very suddenly.
39
Heinz bodies are associated with which condition?
Thalassaemia and G6PD deficiency
40
What is the reversal agent for dabigatran?
Idarucizumab
41
What is acute sickle chest syndrome?
New pulmonary infiltrates on chest x-ray Fever, cough, sputum, dyspnoea, hypoxia
42
In patients with both B12 and folate deficiency - which must you replace first?
Must replace B12 first due to risk of cord degeneration
43
Shisctocytes are associated with which bleeding disorder?
DIC
44
What blood film abnormalities are seen in hyposplenism?
Howell-Jolly bodies target cells Pappenheimer bodies acanthocytes siderotic granules
45
What are the biochemical signs of tumour lysis syndrome?
High potassium High phosphate Low calcium Allopurinol is sometimes used as prophylaxis
46
What is the transfusion threshold for patients with ACS?
80
47
Which blood component has the highest risk of bacterial contamination?
Platelets
48
How long before an operation should you stop the oral contraceptive pill?
4 weeks
49
Deficiency in which clotting factors cause haemophilia?
Haemophilia A - VIII (8) Haemophilia B - IX (9)
50
What are the inherited versus acquired thrombophilias?
Inherited Factor V Leiden Protein C or S deficiency Acquired Antiphospholipid syndrome Essential thrombocythaemia
51
What is the preferred anticoagulant for antiphospholipid syndrome?
Warfarin
52
What is the treatment for sickle cell disease?
Hydroxyurea *Main SE is reduced sperm count in males (returns to normal after drug cessation) Folic acid and Vit D replacement Vaccinations
53
What are the two types of sickle cell?
SS - can lead to severe crisis, all patients need to be on hydroxyurea if symptomatic Sc - ophthalmology problems - need to refer to them, don't all need to be on hydroxyurea
54
What should you suspect if the MCV is 'too low' for the anaemia - eg Hb 100 but MCV 60?
Thalassaemia
55
Which blood test changes might you see in haemolysis?
Normocytic anaemia High bilirubin
56
Which medications can cause B12 deficiency?
Colchicine Metformin PPI Pregabalin topiramate
57
What is MGUS?
Monoclonal gammopathy - Paraprotein band but bence jones -ve Low risk of transformation to myeloma and asymptomatic **Note polyclonal gamopathy is different and doesn't need investigated - it usually is just some sort of reactive change
58
What is MBL?
Monoclonal B cell lymphocytsosis Lymphocytes <5 (in CLL would be >5) Small risk of progression to CLL

Which cells are abnormal in myeloma?
Plasma cells
