Anaemia Flashcards
Review on the 2nd and 21st of every month
(think general, heart, neuro, and other)
presenting complain
anaemia
Fatigue, SOB
Palpitations, angina, CCF
Headaches, TIA’s, retinal bleeds
intermittent claudication
Observations in someone with Anaemia
what can we see on them which makes us think where is the IRON
pale, (pruritis, koilonychia), (jaundice)
Depends on cause of anaemia
Investigations when anaemia is suspected
what tests should we run, what do we need to know
bloods (FBC, U&E, LFT, TFT, ESR/CRP, ferritin)
coombe’s test
Fine needle aspirate - investigate the bone marrow
Ferrokinestics and RBC survival
causes of microcytic anaemia
three main groups and then sub causes
Microcytic anaemia
Iron deficiency - decreased supply or increased demand
haemoglobinopathy - thalassaemia or hereditory spherocytosis
bone marrow hypoproduction - chronic disease, sideroblastic, or poisoning
causes of normocytic anaemia
THree main areas and acronyms within these areas
acute haemorrhagic
haemolytic - haemoglobinopathy, membrane defects, enzyme defects
cont = SPLITTING
Bone marrow hypoproduction - APLASTIC
cont = bone marrow replacement, chronic disease, diet, endocrine
causes of Macrocytic anaemia
8 main causes
megaloblastic - vitamin B 12 deficiency
Folate deficiency.
Alcoholic liver disease
Reticulocytosis
Myelodysplasia
aplastic anaemia
leukaemia
iron disorders
endocrine
causes of Haemolytic anaemias
hereditary
Haemoglobinopathy
membrane defects
enzyme defects
which hereditary membrane defect causes microcytic haemolytic anaemia?
hereditary spheropcytosis
Which hereditary haemoglobinopathy causes microcytic anaemia
haemolytic anaemia
thalassaemia: ineffective erythropoiesis and haemolysis
which hereditary membrane defect causes normocytic haemolytic anaemia?
haemolytic anaemia
2
hereditary elliptocytosis
hereditary stomatocytosis
Which hereditary haemoglobinopathy causes normocytic anaemia?
haemolytic anaemia
3 of them
Sickle cell, unstable Hb and altered O2 affinity.
altered Hb inlcude koln, seattle, zurich and yakima
what hereditary enzyme defect causes normocytic haemolytic anaemia?
honestly this feels stupid by now
2
G6PD
pyruvate kinase deficiency
what are the aquired immune causes of haemolytic anaemia?
TAN, NIPPY, A, A
toxins
autoimmune
neoplasia
neoplasia
infection
paroxysmal cold haemoglobinuria,
primary autoimmune measles,
syphillis
allo-immune
antibiotic induced
what are the aquired non immune mediated causes of haemolytic anaemia?
MMMM
4
medications
MAHA
Malaria
Membrane disorders
presenting complain of haemolytic anaemia sufferers?
what do they present with (which symptoms)
ABCD
Anaemia - due to haemolysis or associated aplastic crises.
Breakdown products - jaundice, pigment stones, haemoglobinuria
Compensation - hepatosplenomegaly, medullary hyperplasia, iron overload
Disease specific - sickle cell, PNH, cold autoimmune
