Passmed haem Flashcards
Which is affected in haemophilia
APTT
PT
Bleeding time
APPT - increased
Reversal of: Warfarin Heparin dabigatran Other NOACs
Warfarin - Vit K + FFP
Hep - protamine
Dab- Indarucizumab
beriplex
What is the indicator of cell lysis in haemolytic anaemia
LDH
[bilirubin too]
Common class of drug causing haemolytic anaemia
NSAIDS
Coombs with hereditary spherocytosis
negative
therefore if +ve and sphereocytes = autoimmune
Cleareance of
Dabigatran
Rivaroxaban
Apixaban
Dabigatran -= renal
Rivaroxaban - liver
Apixaban - poo
which NOAC for people with renal impairment ?
apixibam
Cause of aplastic crisis in sickle cell?
parovirus
-> fsudden fall in Hb
What is a sequestration crisis in sickle cell?
sickling within organs such as the spleen or lungs causes pooling of blood with worsening of the anaemia
What condition can malaria prophylaxis cause haemolytic anaemia in ?
G6PD deficiency
Seen on blood film G6PD deficiency
Heinz bodies
Anaemia / thrombocytes in alcoholic ?
Macrocytic (lose folate)
thombocytopenic
Hb 9.2 g/l (Low)
Platelets 701 * 109/ (raised)
WBC 9.8 * 109/ (normal)
Neuts 77% (raised)
Lymphs 17% (low)
Eosin 2.4% (normal)
What you thinking? why?
CML (Thrombocytosis + raised neutrophils )
What drug used to reduce platelets in CML
hydroxyurea (hydroxycarbamide)
blood film of myeloma? urine?
‘rouleaux formation’
-stacking of RBCs
bence jones in urine
After DVT what is this describing ? painful, heavy calves pruritus swelling varicose veins venous ulceration
post thrombotic syndrome
-> compression stockings
DIC - pt?aptt?bleeding time? platelets?
Low platelets
High everything else
What is the main factor in bleeding time?
platelets - eg asprin increases
Warfarin/noac/heparin - will be normal
Heparin affects what bleeding study?
APTT
PT also sometimes longer
Warfarin affects what bleeding study?
PT
Most common cause of increased VTE risk? name 1 aquired
Factor V leiden - Activated protein C resistance
[protein c/s deficiency are others]
Antiphospholipid syndrome
Raised ESR + Osteoperosis =
Myeloma
abdominal pain and a motor periperal neuropathy
lead poisoning
Bleeding time in
VWD
Haemophilia
vit K def
VWD - prolonged
Normal in others
Acute haemolytic Transfusion reaction mx
Iv fluids + stop transfusion
blood film with target cells
Howell-Jolly bodies
Hyposplenism eg. splenectomy
‘tear drop’ cells on blood film
myelofibrosis
normocytic anaemia, gallstones and family history
Hereditary spherocytosis
‘starry sky’ appearance on lymph node biopsy
burkitt lymphoma
tamoxifen increases risk of?
VTE + endometrial cancer
enlarged lymph nodes become painful on alcohol consumption
Hodgkin
what is seen in blood film of hyposplenism
target cells, Howell-jolly bodies
