Q

RDW is what and normal range

A

Variation in size of RBC
12%-15%
High variation is more in anemia (esp, in Fe+3 deficiency)

Q

Iron Studies what it means :
Ferritin
Transferrin
Total Iron Binding Capacity

A

Ferritin : Fe storage , best way to measure amount of iron in blood
Transferrin : iron transporting protein (high during anemia = TIBC) = to confirm Fe+3 deficiency anemia
= low in Anemia of chronic disease

Q

Anemia and Reticulocyte count is high

What do I do now

A

Reason through if it is blood loss or consumption issue

  • LDH, Haptoglobin, Bilirubin = hemolysis
  • find bleed

Q 
CASE 1 : male 68yo, 3mo of easy fatigabilty, dyspnea on exertion
Fingernails tear, looks skinnier, drinking pain used on car , nails are curled and lines
PE : pale and conjunctiva pallor bilaterally, inflammation on corner of mouth 
- low Hgb
- low Hct
- normal WBCs and Plt 
- low reticular count
-MCV LOW
- high RDW
- low ferritin, and high Transferrin 
- Transferrin saturation % = LOW
= what is it and what do you do
A

= Fe+3 deficiency (IDA)
due to the high transferrin = high Total Iron Binding Capacity
Low T sat = stored/capacity
= find out reason, change in bowel habits, blood in stool, vomit blood, diet….

Q

How does inflammation increases Ferritin

A

Inflammation :

  1. Decreased absorption of Fe
  2. Decreases EPT production
  3. Increases HEPCIDIN : increases Ferritin and lowers Transferrin/Ferroportin

Q

How to TX ACD

A
  • TREAT cause of the anemia
    (Don’t give Fe+3 supplements without knowing cause of problem)
    ** if there is CKD or malignancy = give Erythrocytes Stimulating Factor (ESF) , can give thrombosis however improves anemia

Q

Blood transfusion should be given to

Only for rotations

Study These Flashcards
A

Hgb less then 7 or 8 if pt has acute coronary syndrome or problems

24
Q 
35yo males epigastric pain 3months ago onset, 3 episodes of coffee ground emesis (past 24hrs), OTC antacids help, NSADS taken regularly for various injuries, ABD distention 
- Tachy, hypotension, cool extremities = not good HYPOVOEMIC SHOCK
- pallor 
- VERY low hgb (6)
-low Hct 
- normal WBC, plt
- retic count normal, RI low 
MCV : normal
Study These Flashcards
A

UGIB and in hemorrhagic shock

  • normal retic count - since it’s acute bleeding
  • RI is usually high in acute bleeding so its low here because : BM has not been able to start making more
25
Normocytic anemia + normal reticulocyte count when there is hypovolemic shock is now
Hemorrhagic shock | Uncompensated blood loss —> BM has not had time to compensate
26
What can happen from anemia from acute blood loss
Renal failure MI Hypovolemia
27
TX hemorrhagic shock
1. Apply pressure and compression when you can 2. Give blood and fluid (2 IVs), O- blood 3. Surgery and suture up the bleed
28
If someone is visibly bleeding and there Hgb is normal what do you do
Give them blood and fluids still
29
who makes Anti-D AB
Someone who is Rh-
30
What to do if mom is Rh- and fetus is Rh+
Give Rhogam to mom (it is a drug antibody against the Anti-D AB)
31
4yo AA right leg pain in hip, trauma moved states to higher elevation - SOB when playing, - FH of blood in urine, and anemia - tachy, and HTN, 91% O2 sat - crackles in left base lung - LUQ tenderness and fullness - low Hgb and low hct - WBC and plt low - MCV low - RDW HIGH - Retic count is low , RI low
He has SC And osteonectrosis in hip femoral hip Usually a SC crisis has a high Retic count however it can be low also = give opioids = transfusions to reduce HgS less then 30 (high alloimmunization + FE iron overload)
32
3 common presenting sx of SC
1. Microvascular occlusion 2. Tissue damage 3. Chronic Hemolysis 4. Stroke 5. Thrombosis 6. Acute Chest Syndrome : fat thrombus from the necrosis of a bone (pulmonary infiltrate on CXR, hypoxemia, SOB, fever) pneumonia **** 7. Kidney/spleen problems
33
Acute Chest Syndrome how to TX
= give pneumonia medication (in case) | =transfusion and O2 given
34
Kidney problems in SC
1. Polyuria (can’t concentrate urine) 2. Hematuria (even SC trait can have it) 3. Vasocclusion of small vessels
35
Osteomyelitis is what
Fever and hip pain (infection in the dead bone)
36
Spleen problems in SC
Hypovolemia Splenomegaly Autosplenectomy (splenic infarcts)
37
No spleen casuals what common things
Encapsulated infections | Dots in the RBCs
38
How to TX SC crisis
1. Start O2 and exercises (blow in from a tube as much as you can to expand the lung)-center spirometer 2. Control pain : opioids, NSAIDS, Tylenol (to help breathing, oxygenation, hostle behavior) 3. Check in on them often (like after 4hrs)
39
What can cause SC crisis
Cold weather and high elevation
40
Hydroxyurea
Upregulate HgF Downregulate HgS = for SC patients = can cause FE overload
41
Exchange transfusion in SC
Take out there old blood put in new blood | - prevents iron overload
42
Stem cell transplant in SC
Only for under 16yo Can be curative With 10% mortality rate
43
``` 25yo female with 1 week fatigue, weakness, dizziness, red spots all over the shoulder where she has her purse , gingival bleeding, - she had a UTI and was TX with ABs - pale and tired, conjunctival pallor, petechiae - low Hct - low Hgb - low WBCs - Low plt - MVC HIGH - Retic count low, RI low - normal RDW - BM only fat - ```
Panocytopenia **** | Aplastic Anemia
44
What can cause AA
Drugs Virus Radiation/benzene Fanconi anemia
45
AA TX
Transfusion support and Growth factor support | = if nothing then stem cell transplant (young respond to this more
46
B12 foods
Dairy, cheese, fish, meats, fortified food | Deficiency happens over years
47
Other name for B12
Cobalamin
48
B12 deficiency can happen from
``` Diet Gastrectomy Crohn’s disease Gastric bypass Pernicious anemia ```
49
B12 deficiency confirmed by
HGIH Methylmalonci acid and Homocysteine | Low B12 vitamins
50
Folate Deficiency confirmed how
High homocysteine only
51
Other name for Folate
VIT B9, folic acid | Takes some months
52
Folate deficiency can happen from
``` Diet Crohns celiac Pregnancy Mx like Methotrexate (SLE,RA) ```
53
Folate in absorption is where
Jujunnium and lillium
54
Low MCV | Normal RDW
ACD
55
Normal MCV | Normal RDW
ACD
56
HIGH MCV | Normal RDW
Chemo, Anti-viral medication, alcohol in excess, | APLASTIC ANEMIA
57
