Q

How to measure the properties of RBCs

A

MCV(mean corpuscular volume) = Hct/RBC

Q

Polychromatic cells

What are they and how to confirm

A

They are Reticulocyte with a small RNA in them, they look more purple in color and slightly bigger then the RBCs
- confirm with supravital stain that stains the RNA inside it

Q

Acute Blood Loss causes what to happen immediately and overtime

A

No difference in MHV and all other properties
- BP down, pulse up

OVERTIME :
- blood left pulls fluid from body = Hct and Hgb goes down (6-7hr later)

Something is taking up space in the BM , preventing blood cells from maturing and being made

  1. Cancer (neuroblastoma)
  2. Necrosis
  3. Fibrosis
  4. Inflammation
82
Q

Myelophthisic anemia causes what and what do you see on the blood smear

Platelet function test, morphology

90
Q

A

Low platelets that can be very low (below 150,000) and still have no sx
When it reaches 50,000 you see sx
At 20,000 you have spontaneous dangerous bleeds

93
Q

HIV - associated thrombocytopenia

A
  1. Infection goes to BM and it’s hematopoietic stem cells = no platelet production
  2. Auto-Ab against Platelets made
94
Q

Drug induced thrombocytopenia

A
  1. Myelosuppression : chemo, chloramphenicol, Penicillamine , Gold salts (for aplastic anemia) = no P made
  2. Drug- induced immune thrombocytopenia : Quinidine, Vancomycin, Heparin = destroy P in periphery by drug induced Abs
95
Q

Heparin and drug induced thrombocytopenia

A

Heparin binds to the PF4 complex which then binds to platelets
This causes IgG to come and opsonizing it
- thrombocytopenia + thrombosis

96

  2. More in kids
102
Q

TTP and HUS happens how

A
  1. An exaggerated platelet plug forms and consumes all platelets

103
Q

TTP and HUS on Blood smear

A

You see

  • no platelets
  • some uncleared RBC due to mature RBCs getting sheared
  • schistocytes : sheared RBCs
104
Q

What exactly happens in TTP

A

The vWF and platelets make the platelets plug and the PROTEASE is what prevents the plug from growing too big
** ADAMTS13 mutation on protease so body has Abs against it = X protease
= microvascular thrombosis

105
Q

TTP TX

A

Plasma exchange therapy

Exchange all plasma with new plasma what has no ADAMS13 mutation on the protease

112
Q

Grey Platelet Syndrome is what

A

X a-granules in the platelets

(They contain , Factor 5, vWF, fibrinogen)= bleeding, big and grey and no granules in platelets blood smear

113
Q

vWF in secondary Hemostasis

A

vWF in circulation binds to F8 and carries it to the platelet plug and then it can convert F10 —> F10a

114
Q

vWF D not enough of this

A

Type 1 and Type 3(worse has absolutely no vWF = coagulation and platelet disorder )
1C= makes it only it gets rapidly broken down and cleared

115
Q

vWF D qualitative

A
Type 2 ( 2A no multimer forming)
Defected ligand factors
116
Q

Hemophilia SX

A

Arthrphathy
Hemorrhage in retroperitoneaum or soft tissues
Muscle hematoma

117
Q

Hemophilia A and B

SX

A
A : F8
B : F9
- deep bleed after trauma
- isolated PTT
- X-linked
118
Q

Hemophilia A and B TX

A

Replacement factor or F8 or F9

119
Q

Plt : N
PT : N
PTT : HIGH

A
  • X F11
  • mild to moderate hemophilia A or B (injury bleeding)
  • mild vWF (spontaneous bleeding)
  • severe vWF, Hemo A/B (Severe spontaneous bleeding)
  • heparin, lupus anticoagulant (no bleeding)
120
Q

Plt : N
PT : High
PTT : N

A

X F7

121
Q

Plt : N
PT : High
PTT : HIGH

A
  1. X F2, F5, F10 (common pathway)
  2. Afibrinogenemia
  3. X F5+F8
122
Q

Plt : LOW
PT : High
PTT : HIGH

A

DIC (Disseminated Intravascular coagulation)

Liver disease

123
Q

DIC (Disseminated Intravascular coagulation)

A
  1. Thrombohemorrhagic disorder (too much spontaneous coagulation formation , thrombi)
  2. Consumptive coagulation (bleeding, no coagulation lefts to fix it)
    = widespread thrombosis all over in tiny vessels
124
Q

DIC (Disseminated Intravascular coagulation) caused by

A

Too much tissue factor released

125
Q

DIC (Disseminated Intravascular coagulation) SX

A
  1. Consumption of all clotting factors
  2. Ischemia tissue damage
  3. Bleeding (X coagulation, + thrombosis activated plasmin = fibrinolysis)
126
Q

DIC (Disseminated Intravascular coagulation) can cause what to happen

A
  1. Black fingers and toes

2. Hemorrhage of the adrenal glands = Waterhouse- Friderichsen Syndrome

127
Q

DIC (Disseminated Intravascular coagulation) DX

A
  1. Low PLT
  2. HIGH PT and PTT
  3. HIGH D-dimes (product of plasmin lysine coagulation factors = fibrinolysis)
128
Q

transfusion screens for what

A
  1. Donor HEP, HIV

2. Blood tested for : HIV, HBV, West Nile, Zika, chagas, syphilis, hcv, htlv

129
Q

How can a donors blood get infected

A

Sometimes especially platelets that are stored at room temperature can get infected by bacteria if contaminated in any way
= recipient gets hypotensive and febrile immediately during trasnfusion

130
Q

Acute immune hemolytic reaction happens how and when

A

If mismatched blood type happens

- by IgM antibodies

131
Q

What does it mean o be A- or B- or AB-

A

You are Rh- and you have Anti- D Ab

Rh+ has no Anti-D Ab

132
Q

Delayed immune hemolytic reaction happens how and when

A

During transfusion or mixing of blood that is Rh+ and Rh-
= makes IgG, so the first time its exposed it is fine only the second time there will be hemolysis and problems
(ESP Rh- mom and Rh+ fetus)

133
Q

2 types of delayed immune hemolytic reaction

A
  1. Rh+ fetus and Rh- mom
  2. IgA deficiency patient getting a blood transfusion
    = uses IgG
134
Q

IgA deficiency patient getting a blood transfusion what happens

A

The pt has Anti-IgA IgG-antibodies that attack any IgA that it gets from any transfusion
= anaphylactic reaction
= you need was the blood before giving it

135
Q

Acute Lung Injury (TRALI)

A

Transfusion related

= inflammation and infiltrates start to accumulate in the lungs of recipient (acute resp failure)

136
Q

Acute Lung Injury (TRALI) SX

A

Difficulty breathing
Fever + Hypotension (mimicking sepsis)
= during or after transfusion

137
Q

Immune modulation (TRIM)

A

Transfusion related
When a pt is being transfused :
1. Immune system is somewhat pro-infammatory state always
2. Immune system is also downregulated from pathogens and things happening in the body that actually need to be taken care of due to being distracted by the transfused entities
** really make sure patient needs a transfusion, PROS over CONS
