whats the normal

WBC
PMN
EO
Baso
Lymph
WBC- 5-10,000
PMN- 1500-6500
EO- 0-500
Baso 0-200
Mono 1-600
Lymph- 1200-3400
what is granulocytopenia
what is the numebr
granulocytes are PMN, EO, and baso.

often just refers to PMN bc the other are in such low numbers

<1500

aka:
neutropenia
agranulocytosis
what can cause granulocytopenia
1. Ineffective granulopoiesis: decreased myeloid stem cells, drugs, DNA defects

2. Decreased Production: myelopthisic anemia- Cancer, infection, Leukemia, lymphoma, Gauchers
, Aplastic anemia, large granular lymphocytic leukemia

3. Destruction/Removal: SLE, drug reaction, splenic sequestration, infections
what is granulocytopenia, what else is it called
low PMN (granulocytes)

Neutrophilia <1500
Agranulocytosis <500

<1500
what is leukopenia, what 2 general things cause it
decreased peripheral WBC

1. Granulocytopenia (low PMN)
2. Lymphopenia (bc of HIV or drugs)
in general granulocytopenia is low PMN and can be caused by decreased production or increased destruciton. waht are some specific causes
1. Myelopthisic Anemia: this gives a pancytopenia (Cancer, Infection in BM)

2. Aplastic Anemia: stem cell failure, also pancytopenia

3. Large Granular Lymphocytic Leukemia: pancytopenia, neoplastic cells suppresses BM

4. B12/Folate deficit: megaloblastic anemia

5. Myelodysplastic syndromes:

5. SLE

7. Splenic sequestrayion

8. Bacterial infection

9. Drugs/EtOH: most common!

10. Acute Leukemia. myelopthisic disease
if you have a pneumonia wht can happen to PMN
increased removal --> neutropenia!

<1500
left shift (more bands)
what is the most common reason a person will have LOW PMN
drugs

ex chemo, immunologic, idiosynchratic, EtOH
what is the clinical course of someone with decreased PMN (neutorpenia, granulocytopenia)
Agranulocytic Angina

**get ulcers in mucosa (mouth is common)

**risk of deep bacterial/fungal infection. aspergillious, candida
if what numbers are low can you get oral (mucosal) ulcers and increased risk for deep bacterial and fungal infection
neutropenia
At age 6, Amber was treated for acute leukemia.
During course of therapy, she developed a
sinus/facial infection with fungus
(probable Aspergillus)
Extensive surgery required to excise necrotic
infected tissue including Amber’s eye
Aspergillus invades the walls of blood vessels in
severely neutropenic patients; causes tissue necrosis
Why does Amber have neutropenia?
1. leukemia decreases PMN
2. chemo drugs kill PMN

**
whats the deal

WBC 3000
Hb 7

whats the ddx
call hematologist, pancytopenia

1. Acute leukemia
2. myelophthisic anemia
3. Aplastic anemia
4. myelodysplastic syndrome
what do lymphocytes do in pancytopenia
NOTHING, lymph have nothing to do with pancyto (thrombopenia, anemia, neutropenia)
whats hte ddx for pancytopenia

Plate 1800
Lymph 60
3nRBC/100WBC

what is a common cause of these findings?
what fo test should be done?
macrocytic anemia and thrombocytopenic,

LYMPHOPENIC (recall this doesnt mean pancytopenia)- no lymphs means:
1. HIV
2. Drugs
what numbers define lymphocytopenia
when absolute is <1200 adults or <3000 in children

1. malnutrition
2. HIV
3. Corticosteroids
4. TB
5. Radiation, SLE
what will malnutrition do to CBC, what else will cause the same thing
NO lymphs! <1200 adult or <3000 kid

also caused by:
1. HIV, congenital immune deficit
2. corticosteroids
3. TB
4. Radiation, SLE
what is reactive leukocytosis
1. reactive means its inflammatory

>10,000 WBC in circulation

increased PMN common for adults
increased lymph common for kids
what do corticosteroids do to:

1. Lymphs
2. PMN

What do glucocorticoids do to Eosinophiles
1. decrease lpmyhs
2. increase PMN (prevent PMN from entering tissue so it stays in periphery)

Glucocorticoids will decrease Eisionophiles (given to treat Asthma which has high IgE/eosionophiles)
why might one have neutrophilia
1. infection (bacteria)
2. sterile inflammation/necrosis/burns
3. glucocorticoids- keeps PMN in circulation and prevent them from entering tissue
4. exercise
5. catecholamines
ok so we know and MI will increase PMN, as will exercise and catecholamines. what cytokines cause more PMN to pour out of the BM?

what makes you INCREASE production (rather than just push them out)
TNFa, IL1

**will see a fast reaponse, incerased bands. we pull from BM when there is infection, sterile inflammation (MI), or endotoxin

((MAKE more we need GF and its a slow response
with severe inflammation we know we have increased PMN, do they look different
Toxic Granulation: dark staining

Dohle Bodies: blue stained bits of ER

will also see cytoplasmic vacuoles
when and where do we see Dohle bodies
they are dilated ER that stain blue, seen when there in an infection that increases PMN counts

**will also have toxic granules (dark staining) and cytoplasmic vacuoles
what PMN changes are seen with severe inflammation
1. increased numbers
2. Dohle body- dilated ER, stains blue
3. Toxic granulation- dark staining
4. vacuolization
what is leukemoid reaction
what is left shift
1. Leukemoid reaction- granulocyte counts >50,000 (recall really low granulocyte counts was agranulocytosis)

2. left shift- too many bands
if we see a peripheral smear and we see WAY too many PMN what might we call it
neutrophilia but also leukemoid reaction

recall leukemoid reaction is >50,000! TONS

**typically with leukemoid we also see increased band cells
A 61 y/o woman presents to the emergency
department with fever, rigors and tachycardia.
Blood cultures demonstrate gram negative bacilli
identified as Enterobacter cloacae.
Review pictured smear. What leukocytes
are present?
What is her total WBC count likely to be
what cytokines are active
1. gram (-) can be endotoxin, this causes INCERASE in PMN

will have left shift, lots of bands (also have dohle body, vacuouls and toxic granulation)

increased WBC- leukemoid reaction

IL1, IL6, TNF, CSF
The patient is a 55‐year‐old white man who
presents to the emergency room complaining
of chest pain and labored breathing. His
temperature is 98.6°F. He is overweight and
smokes two packs of cigarettes a day. His

WBC are high normal is 5-10,000
this is a L shift neutropenia- this is bc of the necrosis associated with MI

released normally as a seg, released early as a band when the BM is stim to push them out fast
what is the leukoerythroblastic reaction? what usually causes it
nRBC in periphery. you should NEVER see this. also will see immature PMN with it

caused by these space occupying leisions:
malignancy
myeloproliforative disorder

what do we see on CBC for CML
anemia
platelets do thier one thing
GRANULOCYTOSIS WITH LEFT SHIFT, PMN are always increased
LAP- leukocyte alkaline phosphatase is decreased
HYpercellular BM with <20 blasts
if your BM is hypercellular with MORE than 20% blasts is it chronic or acute leukemia
acute

chronic- less than 20% but still hypercellular
are leukocytoes ALWAYS increased in chronic leukemia
yes! and hte BM is hypercellular with less than 20% blasts

contract to acute leukemia: WBC can be up down or normal and BM is hypercellular with more than 20% blasts

what does myelodysplastic syndrome mean
pre leukemia of hte myeloid line
what is myelodysplastic syndrome?
How is it different from Myelodproliforative?
Myelodysplastic: pre cancer, stem cell problems mean there is ineffective erythropoiesis, not enough cells in periphery, cytopenia. progress to AML

Myeloproliforative: too many cells in the blood
what is the natrual history of MDS (myelodysplastic syndrome)
can become acute leukemia

**recall myelodysplastic is where there is a stem cell disorder that leads to ineffective hematopoiesis which leads to cytopenia and increased risk of AML
who might have an increased risk of AML, and some cytopenias bc they have a stem cell problem that gives ineffective erythropoiesis (ie MDS)

what is the cayse
more likely in older ppl, more common than Acute leukemia in this patient age group

M>F, insidious

Cause: insidious common, therapy related, genetic stem cell damage
what are some morphologies of MDS (myelodysplastic syndrome)

BM
Peripheral
MDS- inefective hematopoiesis, increased risk of AML

BM: Hypercellular, megaloblastoid maturation, ringed sideroblasts


Peripheral Blood: pancytopenia, MCV increased, pseudo-Pelger-Huet cells (binucleate granulocytes)
if you see pleger huet cells in the peripheral smear what might you find inthe BM
Pleger Huet- common in myelodysplasia, its a binucleate granuloctye

BM: hypocellular, ringed siderophages, megaloblastoid maturation (dysplastic magakaryocyte)

**recall MDS is bad stem cells that make hematopoiesis ineffective. we get pancytopenia and increased risk for AML
when is this seen: Bone marrow aspiration:
Megaloblastoid dyserythropoiesis

what else is seen in BM

what is seen on peripheral
myelodysplasia

also see:
dysplastic megakaryocyte
ringes siderophages- Fe, prussian blue

Peripheral blood: binucleate granulocytes called Pelger Huet
what is 5 q syndrome
its seen in older women with MDS (remeber there were stem cell defects so no hematopoiesis, and there were lots of karyotypes)

there is megaloblastic anemia with ringed sideroblasts, platelets are normal and have a GOOD PROGNOSIS
whats the prognosis and tx of myelodysplastic syndrome (MDS)
refractory anemia, up to 5 year surviva, but usually a 1-2 year survival

**die due to:
Acute leukemia
PMN low- infection
Bleeding- thrombocytopenia
what is myeloproliforative disorder (MPD)
Multipotent myeloid clonal transformation (CML is pluirpotent)

Polycythemia vera
thrombocytothemia
primary myelofibrosis
A 50 y/o woman has purpura, headaches, and abdominal fullness. Her BP is 160/85 and is slightly blue. Overall she looks bloated (plethoric)

Her hemoglobin is

Abdominal CT shows massive splenomegaly

What is the Dx?
Explain the CT finding.
What complications may occur?
Hgb is HIGH- polycythemia
Platel high
WBC high

MPD- polycythemia vera (EPO normal, get proliforation bc of JAK mutation)

**worry that with the granulocytosis you have increased basos- their histamine can cause itching, and peptic ulceration

**risk for both bleeding and thromboses
polycythemia

1. pathogenesis
2. labs
3. clinical
1. pathogenesis: JAK mutation leads to constant erythroid production, EPO is NOT high

2. labs- Hgb/WBC/Plate all are high (polycythemia, granulocytosis, thrombocytosis) rich thick blood

3. clinical: splenomegaly, hypercellular BM. older ppl. excess body fluid (plethoric) cyanotic, HTN, HA, Histmince from basophils makes you itch and peptic ulcers and skin ulcers
which MPD comes about bc of JAK mutation?

who might we see this in, what is their clinical presentaiton
polycythemia vera- EPO independent increase in RBC production, also get granulocytosis and thrombocytosis. its a really rich thick blood

seen in older ppl, they have excess body fluid (plethoric) and are cyanotic. splenomegaly, HTN, HA, Histamine from excess basophils leads to peptic ulcers and puritis. skin ulcers
ok so polyvythemia vera is an increase in RBC and you get thick rich blood. what is the risk of bleeding
increased bc of stagnant flow- and you have lots of platelets so can also thombose
how is polycythemia treated
you bleed them!

**the problem is lots of RBC production bc of a JAK mutation (NOT EPO) so get rid of some of the blood

**keep in mind with PVC you have increased risk of BOTH bleeding and thrombosing

• What is rouleaux? Is it the same as agglutination?
• What is the diagnosis?
• How is the diagnosis made?
Ca is high
kidney is affected
macrocytic anemia

Rouleaux- RBC stick together bc they are not being repelled by albumin or there is TONS of Ig from plasma cells

Dx: multiple myeloma, confirm with BM
in what disease do you see rouleaux?
RBC stacked like pancakes bc of TONS of Ig, in MM

**Not the same as agglutinin- this required AB
what is the pathogenesis of MM
common, plasma cells in BM makes nodules

1. normal
2. infection or inflammation (HIV, osteomylitis, RA) paired with some genetic instability --->
3. BAD NEWS! there is monoclonal gammapathy of Uncertain significance
4. PLasma cells secrete IL6 and others to activate osteoclasts
5 leads to bone destriction and WAY to many Ig- thich serum, proteinuria-renal damage, suppression of normal humoral immunity- risk of inection
in MM there is a single cell in a predisposed pt (HIV, RA, osteomylitis, genetic, radiation etc) who gets a genetic instability, what does this lead to
MGUS- monoclonal gammaopathy of uncertain significance

**this is a PREcancer can turn into MM (or not) and secrete IL6 and others. leads to bone resorption and TONS og Ig (lots of Ig means- thick serum, renal dalage- too much protein, suppression of normal humeral immuniety)
what does MM look like

bone
kidney
BM
systemic
late disease
bone punch-outs

**IL6- osteolytic activity: vertebrae, ribs, SKULL. Bone pain HYPERCALCEMIA

KIDNEY: bence Jones light chain, clogs the pee so you get casts in teh pee

BM: Russel bodies, inclusions of Ig in plasma cells. Plasmacytosis

AMYLOID: congo red

Plasma cell Leukemia: plasma cell in the periphery, shoudl NEVER see this. ?
who gets bence Jones? Is it the same person that gets russel
YES! MM for both- the B cell neoplasms that punches your bones out

**the kidney gets clogged bc you make TONS of Ig- this excess protein is damaging

**the BM is making TONS of plasma cells and they get RUSSEL BODIES- inclusions of Ig in the malignant plasma cell (Mott cell)
whats a Russel Body
in MM its a plasma cell in the BM with Ig inclusions bc its trying to make SO MANY Ig

In MM we will have bone punch outs. Bence Jones in kidney, Russel in BM Mott cell (malignant plasma) and amyloidosis
whats a Mott cell

causes of ruptured spleen/splenectomy
trauma- will have intraabd hemorrhage and hypovolumic shock
spontaneous in mono, maleria, leukemia

**when spleen is gone you get nRBC, howell jolly body, target cells, susceptible to encapsulated (strep pneumonia)
if you have had MVA nad have intraabdominal hemorrhage, hypovolumic shock what can have happened
