Q

Management of acute episodes of bleeding in haemophilia

A

Infusion of clotting factor
Desmopressin to stimulate VWF
antifibrinolytics

21
Q

Give an example of an antifibrinolytic

A

Tranexamic acid

22
Q

Von willebrands disease

A

A deficiency or abnormality of VWF

23
Q

Where is the VWF gene located

A

Chromosome 12

24
Q

Consequence of low VWF

A

Impaired platelet adhesion to the subendothelium

25
Q

Consequence of reduced VWF on other clotting factors

A

Causes factor VII deficiency as it is not protected from premature degradation

26
Q

Clinical presentations of Von willebrands disease

A

Nosebleeds , menorrhagia etc.

27
Q

Epistaxis

A

Nose bleed

28
Q

Menorrhagia

A

Heavy or prolonged periods

29
Q

Thrombotic thrombocytopenic purpura

A

Formation of small blood clots throughout the body

30
Q

What causes Thrombotic thrombocytopenic purpura

A

Deficiency of metalloproteinase ADAMTS13

31
Q

Clinical presentation of Thrombotic thrombocytopenic purpura (5)

A

Fever
Haemolytic anaemia
Thrombocytopenia
Acute renal failure
Neurological symptoms

32
Q

Blood film in Thrombotic thrombocytopenic purpura

A

Schistocytes and elevated reticulocyte count

33
Q

Urinalysis result in Thrombotic thrombocytopenic purpura

A

Proteinuria and microscopic haematuria

34
Q

Management of Thrombotic thrombocytopenic purpura

A

IV plasma exchange

35
Q

Second line management in patients with Thrombotic thrombocytopenic purpura

A

Splenectomy

36
Q

Massive haemorrhage

A

Bleeding with signs of shock , already required prompt transfusion

37
Q

What can cause haemorrhage

A

Traumatic bleeding
Infection

38
Q

What can we give to patients to replace fibrinogen

A

Cryoprecipitate

39
Q

Role of tranexamic acid

A

Reduces or prevents excessive bleeding by inhibiting the break down of blood clots

40
Q

Causes of secondary ITP

A

Anti phospholipid antibody syndrome
SLE
viral infections (cytomegalovirus, varicella-zoster, hepatitis C, HIV)
h.pylori infection
Meds
Lymphoproliferative disorders

41
Q

What causes immune thrombocytopenic purpura

A

Type 2 hypersensitivity reaction - production of antibodies that target and destroy platelets

42
Q

ITP

A

Immune thrombocytopenic purpura

43
Q

When does ITP usually present

A

Children under 10

44
Q

Usual history in ITP

A

History of recent viral illness

45
Q

Symptoms of ITP

A

Bleeding, bruising and petechial or purpurin rash

46
Q

Investigation for ITP

A

Full blood count

47
Q

Positive result that indicates ITP

A

Isolated thrombocytopenia

48
Q

Usual management of patients with ITP

A

Monitoring until platelets return to normal

49
Q

Management of severe thrombocytopenia

A

Prednisolone
IV immunoglobulins
Blood transfusions if required
