Haem- anaemia Flashcards
anaemia
decrease in haemoglobin in the blood
anaemia in adult males level
Hb <130 g/l
anaemia in adult females level
Hb <120g/l
normal response to anaemia
make more red cells- reticulocytosis
reticulocytes
cells that have just left the bone marrow
size of reticulocytes
larger than average red cells
reticulocytes stain-
purple/deep red
symptoms of anaemia
breathlessness
palpitations
headaches
faintness
fatigue
microcytic anaemia
anaemia caused by deficient haemoglobin synthesis
most common cause of microcytic anaemia
iron deficiency
which cytokine is released due to chronic disease and causes anaemia
IL6
Sideroblastic anaemia
excess iron buildup in mitochondria due to failure to incorportae iron into haem
iron deficiency more likely in who
women and children
causes of iron deficiency
dietary factors
losing too much- bleeding
not absorbing enough- malabsorption
clinical features of iron deficiency (longstanding)
- Brittle nails
- Spoon-shaped nails (koilonychia)
- Atrophy of the papillae of the tongue
- Angular stomatitis
- Brittle hair
- Dysphagia and glottitis
- Generalised pruritis
megaloblastic anaemia
anemia characterized by the presence of abnormally large red blood cells (megaloblasts) in the bone marrow and peripheral blood
Pernicious anaemia
autoimmune condition with resulting destruction of gastric parietal cells- B12 deficiency
sources of B12
animals
sources of folate
Liver, leafy veg, fortified cereals
