Anaemia Flashcards
What are some of the main symptoms of anaemia?
Fatigue Restless legs Dysponea Pallor Hair loss Dizziness Headaches Tinnitus
What are some of the main signs of anaemia?
Glossitis (tongue inflammation) Angular stomatitis Conjunctival pallor Koiknychia Jaundice
What are the main investigations to do for anaemia?
Blood films FBC Ferritin levels RTC Vit. B12 & folate levels DAGT (Coombs test)
What does MCV stand for and what does it tell you?
Mean corpuscular volume
Tells you the volume of the RBCs, so you can find out if it’s micro, normo or macrocytic
What does MCH stand for and what does it show you?
Mean corpuscular hemoglobin
Shows the Hb content of the RBCs
If a blood film comes back that shows microcytic but normoblastic anemia, what should you check that the patient has taken?
Alcohol
What is the function of Glucose-6 Phosphate Dehydrogenase (G6PD)?
Prevents oxidative damage when RBCs are metabolised
What is the function of folate?
Increases the production of RBCs
What is the function of the protein Ankyrin?
Maintains RBC’s membrane
What does Iron do in relation to Hb?
Allows oxygen to bind to it
How many chains does Hb have?
4
2x alpha chains and 2x beta chains
What chromosome number produces the 2 alpha chains of Hb?
16
What chromosome number produces the 2 beta chains of Hb?
11
Why a intrinsic factor important in amemias?
As you need it to absorb vit. B12
What protein transports iron from the duodenum (oral iron obvs) to the blood?
Ferroprotein
What chemical transports iron from the blood to the liver, after ferroprotein transports it from the duodenum into the blood?
Transferrin
Which chemical stores iron in the liver?
Ferritin
What happens to Fe levels due to hepicidin?
Decreases
What chemicals are responsible for:
A. Transporting iron from duodenum to blood
B. Transporting iron from blood to liver
C. Stores iron in the liver
A. Ferroprotein
B. Transferrin
C. Ferritin
Give 2 bacterial infections that cause of anaemia?
TB
Brucella
Give 2 examples of viral infections that cause anaemia
EBV
CMV
Give 3 examples of parasitic infections that cause anaemia.
Malaria
Schistomiasis
Leishmaniasis
Give examples of the following infections that can cause anaemia:
A. Bacterial
B. Viral
C. Parasitic
A. TB and Brucella
B. EBV and CMV
C. Malaria, schistosomiasis and leishmaniasis
Give an example of a connective tissue disease that can cause anaemia
SLE
What is the name of a storage pool disorder than can cause anaemia?
Gaucher’s disease
What are the 2 man broad types of anaemia?
Acquired and congenital
What common stationary utensil are microcytic RBCs suppose to look similar to?
Pencils
What is the main test to do for an acquired anaemia?
Blood film
If tests to you do for the following blood film results:
A. Microcytic and hypochromic
B. Normocytic and normochromic
C. Macrocytic and macrochronic
A. Ferritin levels
B. Reticulocyte count
C. Vit. B12 and folate levels
What are potential causes of anaemia if the ferritin levels of a microcytic and hypochromic anaemia are:
A. Increased or normal
B. Decreased
A. Secondary anaemia or thalassemia
B. Fe deficiency anaemia
What are potential causes of anaemia if the reticulocyte count (RTC) of a normocytic and normochromic anaemia are:
A. Increased
B. Decreased/normal
A. Haemolysis or acute blood loss
B. Secondary anaemia
What are potential causes of a macrocytic and hyperchromic anaemia that show RBCs that are:
A. Megaloblastic
B. Non-megaloblastic
A. Vit. B12 or folate deficiency
B. Myelodysplasia or methotrexate use
Apart from showing non-megalobastic, macrocytic and hyperchromic cell’s on a blood film, what are some other signs of myleodysplasia on a blood film?
RBCs aniscytosis (unequal sizes)
Hypogranular neutrophils
What is the most common cause of anaemia?
Fe deficiency
How is Fe deficiency treated?
Oral or IV iron
Dietary changes
Treating the cause
If a female is having anaemia but is still having periods, should you refer to GI to check for a peptic ulcer?
