19
Q

What are some causes of monocytosis?

A

20
Q

21
Q

What are some causes of eosinophilia?

A

eczema, asthma, hay fever, drug hypersensitivity, parasitic infection, autoimmune (SLE, RA, sclerosis etc), lymphoma, leukaemia, crohns, UC

22
Q

What are some causes of haemolysis?

A

microangiopathic haemolytic disorders, G6PD dficiency, transfusion reaction, drugs, snake venom, severe burns

23
Q

What are the reasons for anaemia of inflammation?

A

inflammatory cytokines suppress erythropoiesis
reduced EPO production and responsiveness
altered iron metabolism and sequestration in macrophages, promoted by increased hepcidin levels due to cytokines
reduced red cell lifespan

24
Q

What are some differences in blood findings between iron deficiency and anaemia of inflammation?

A

ferritin is decreased in i.d, but normal or high in a.o.i
Total iron binding capacity and soluble transferrin receptor are increased in i.d but normal or decreased in a.o.i
Bone marrow iron is absent in i.d but present in a.o.i.
CRP is normal in i.d. but increased in a.o.i

25
Q

What are some blood findings in chronic liver failure?

A

elevated MCV, low platelets, anaemia, neutropenia, acanthocytes and target cells on blood film

26
Q

What are some blood findings in chronic renal failure?

A

anaemia, platelet dysfunction, echinocytes on blood film
