Question 214

Where are smudge cells seen?

Answer 214

Chronic lymphocytic

Chronic lymphocytic leukaemia (CLL) is caused by a monoclonal proliferation of well-differentiated lymphocytes which are almost always B-cells (99%). It is the most common form of leukaemia seen in adults.

Features
often none: may be picked up by an incidental finding of lymphocytosis
constitutional: anorexia, weight loss
bleeding, infections
lymphadenopathy more marked than chronic myeloid leukaemia

Investigations
full blood count: lymphocytosis, anaemia
blood film: smudge cells (also known as smear cells)
immunophenotyping is the key investigation (confirms CLL)

Question 215

A 58-year-old man presents to his GP with increasing tiredness, accompanied by bruising on his legs. He also complains of aching bones. He has no previous illnesses. On examination, he is pyrexial and pale, has bony tenderness over the sternum and tibia, and has petechiae on his legs. A bone marrow biopsy was taken and stained, showing the following: Auer rods

Answer 215

AML

cute myeloid leukaemia is the more common form of acute leukaemia in adults. It may occur as a primary disease or following a secondary transformation of a myeloproliferative disorder.

Features are largely related to bone marrow failure:
anaemia: pallor, lethargy, weakness
neutropenia: whilst white cell counts may be very high, functioning neutrophil levels may be low leading to frequent infections etc
thrombocytopenia: bleeding
splenomegaly
bone pain

Acute promyelocytic leukaemia M3
associated with t(15;17)
fusion of PML and RAR-alpha genes
presents younger than other types of AML (average = 25 years old)
Auer rods (seen with myeloperoxidase stain)
DIC or thrombocytopenia often at presentation
good prognosis

Question 216

Binds to CD20

Rituximab is a monoclonal antibody that is used in various conditions including CLL and Non-Hodgkin’s Lymphoma. It acts by binding to the CD20 protein on the cell surface of B-cells and induces lysis. All the other answers are red herrings and are just there to confuse you.

Question 217

Q7: 68F has been admitted to the frailty unit after a fall at home. On examination she has a dislocated hip and lacerations over her body. She has a BMI of 30 and is on HRT for her post-menopausal symptoms. You consider her to have a significant risk for VTE and begin her on prophylactic treatment. What is the mechanism of action for the prescribed medication?

Answer 217

LMWH

Patient presents with signs of DVT and this is confirmed using a doppler ultrasound. Prophylactic treatment for DVT is using LMWHs and this is the MOA.
LMWH works by binding to ATIII and inhibiting factor Xa. (indirect inhibition)
Warfarin works by inhibiting the reduction of Vitamin K and thus inhibiting production of factors 10,9,7,2 (1972)
DOACs such as apixaban directly inhibit X 🡪 1st line treatment
This is how UH works.
This is the MoA of clopidogrel, an antiplatelet. You wouldn’t use this for DVT.

She complains of headaches and nausea while seated in the A&E department. Bloods show a markedly low platelet count. There is no FHx of bleeding disorders.

Answer 221

Immune thrombocytopenic purpura

ITP is most common in ages 2-6 years old and presents with purpura and nosebleeds. It can also cause N+V, headaches, and bleeding gums. It is an autoimmune condition that can present after a viral infection and is self-limiting in nature. It is treated with prednisolone, IVIg and platelet transfusions.
TTP presents similarly, however has a different pathophysiology and is more common in adults. TTP is a lack of the VWF cleaving protein and on blood film will show fragmented erythrocytes as well as raised creatinine, bilirubin and reticulocytes.
SJS and bullous pemphigoid are dermatological conditions and do not present this way but are just there to confuse you.
Haemophilia doesn’t usually present this way and has a massive genetic component as well as being a largely male disease.

Question 222

A 3Y old male patient with Down’s Syndrome presents to clinic with a two week history of shortness of breath and fatigue. On examination you find hepatosplenomegaly, lymphadenopathy and drooping of the right side of his face.

Answer 222

Acute lymphoblastic leukaemia

ALL is more common in children aged 2-4 years and has an association with Down’s syndrome. ALL affects the lymphoblasts and therefore presents with symptoms of anaemia, thrombocytopenia and neutropenia.
AML presents similarly but is much more common in adults and therefore is unlikely to be the answer in this situation.
CML also affects adults and presents with B-symptoms such as weight loss, fatigue, night sweats and bone pain.
Hodgkin’s lymphoma has a bi-modal incidence and affects young adults and the elderly and characteristically in exam questions has the patient experiencing pain when drinking alcohol.
Kawasaki’s disease is a vasculitis and doesn’t present this way.

Question 223

However he presents to the local emergency department 3 days later after feeling tired and very SOB. When asked about any allergies, he remembered when a doctor told him to not take primaquine due to an inherited disease - but he doesn’t remember its name. On examination he appears visibly jaundiced. A blood film reveals the presence of Heinz bodies and bite cells.
What investigation would confirm the diagnosis?

Answer 225

G6PD enzyme assay

Glucose 6 phosphate dehydrogenase deficiency is a X linked inherited condition which predisposes a patient to haemolytic anaemia due to oxidative stress. The crises in this case was aggravated by gliclazide

Jaundice, pallor, SOB, anaemia, dark urine, nausea, splenomegaly

Question 226

A 44 year old man comes into A and E with significant bruising, epistaxis, fever and gingival bleeding. He ends up being diagnosed with DIC. FBC analysis reveals low fibrinogen levels, what blood product can be used to treat this?

Cryoprecipitate

PCC usually given for the reversal of warfarin during bleeds, head trauma or prior to surgery
FFP can be used to treat clotting abnormalities (PT or APTT elevated)
Packed red cells for chronic anaemia
Beriplex is a type of PCC. (Note vitamin K can also be given to reverse warfarin)
Cryoprecipitate is the correct answer. It is rich in fibrinogen

Question 235

A 77 y/o male patient presents to A&E with with severe rectal bleeding and vomiting blood. You notice on the drug charts that the patient usually takes warfarin due to recurrent clots in the past. The patient mentions that he recently got back from a 7-day bender in Ibiza and had forgot to take his warfarin during that time. When he got back, he decided to take a weeks worth of tablets to make up for the ones he missed.
What would you prescribe to this patient to reverse the effects of warfarin? (Give 2 examples)

Answer 235

Vitamin K or Beriplex

Warfarin inhibits hepatic production of vitamin K-dependent coagulation factors and cofactors. Vitamin K must be in its reduced form for synthesis of coagulation factors. It is then oxidised during the synthetic process. An enzyme called vitamin K epoxide reductase reactivates oxidised vitamin K. Warfarin inhibits vitamin K epoxide reductase which prevents reactivation of vitamin K and coagulation factor synthesis.
