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 Hct 22 (normal is 40-50) MCV 122 Platelets 90,000 |
WBC low
Anemic Platelets low **combination called pancytopenia |
|
whats pan cytopeni
|
low plate, PMN, and anemia
thrombocytopenia, neutropenia, anemia |
|
if we are missing B12 and folate is the only thing we get megaloblastic anemia
|
nope, ALL lines are decreased. will get a leukopenia
|
|
if you see decreased WBC, Anemia and low platelets what do you do?
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
|
1. acute leukemia
2. aplastic anemia 3. myelopthesic anemia 4. myelodysplastic syndrome |

Patient is a 33 y/o accompanied to the ER in an
ambulance by her 13 year old daughter. She is unarousable and unable to give a history. • Her daughter relates that she has been getting progressively weaker for the past few days and has not been out of bed for the past 24 hours. She occasionally retches and has been vomiting for 2 days • Daughter relates a history of ETOH abuse and smoking tobacco. Hb 10 Hct 34 (low) MCV high (103) 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 EKG demonstrates ST segment elevation. Labs include increased CK‐MB and troponin compatible with an acute myocardial infarction His complete blood count (CBC) shows: Hemoglobin (Hb) 13 gm/dL (nl 13.7‐16) White blood cells (WBC) 15,000/mm3 (nl 5,000‐10,000) Platelets (Plt) 350,000/mm3 (nl 150,000‐450,000) Differential of white cell count 80% neutrophils (PMNs) 10% band neutrophils 9% lymphs; 1% monos What does the neutrophil count indicate? • At what stage of development are granulocytes released into peripheral blood? • What are the mechanisms underlying neutrophilia? • What is “left shift” • What is the significance of blasts on CBC |
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 granulomas gaucher disease |
|
what space occupying leision in the BM will cause leukoerythroblastic reaction
|
nRBC in periphery
1. primary/mets cancer 2. myeloproliferative disorder 3. granulomas |
|
A 71 y/o woman with history of chronic
respiratory disease with wheezing presented with productive cough, fever and shortness of breath that began 4 days earlier. • The WBC was 18,400 (nl 5,000‐ 10,000) with 38% eosinophils, 48% neutrophils, 4% monos, 10% lymphs • What abnormality of the CBC is present? • What is the likely cause? • What is the mechanism of WBC change? |
WBC- leukocytosis
EO- HIGH Caused by IgE- asthma, allergy, worm IL5 drives eosinophiles, treat with glucocorticoids |
|
an asthmatic will have what increased? what IL stim it? how can we decrease it
|
Eosinophiles, IgE
stim by IL5 Eosinophiles decrease with glucocotricoid Lymphocytes decrease PMN increase |
|
What are the causes of eosinophilia?
Recognize morphology and breakdown products. What is the mechanism of eosinophilia |
Type I Hs reactions
-asthma, allergies, atopic dermatitis, hay fever EO increase is driven by IL5 charcot leyden crystal is the remnant treat with cortocosteroid |
|
charcol leyden crystal
|
Eosinophilia remnant
*eo increase bc of allergic, type I HS reaction, |
|
what are hte causes of monocytosis
|
1. TB, cocci, maleria
2. Subacute bacterial endocarditis 3. SLE, RA 4. IBS **any granulomatous disease causes monocytosis **recall in inflammation the first responder is PMN but then we get monocytes |
|

|
Acuke Lymphocytic Leukemia (can be B or T, B is better prognosis)
*look for CALLA |
|
what is seen in the CBC for a kid will Acute Leukemia
|
Pancytopenic so CBC:
anemia thrombocytopenic leukopenic BLASTS are seen |
|
whats the BM for Acute leukemia
|
hypercellular, >20% blasts. primitive cells with large nuclei and nucleoli`
|
|
what is leukemia
what is lymphoma |
Leukemia: lymphocyte cancer in the BM
Lymphoma: lymph nodes/extra nodal tissue outside BM |
|
A kid is anemic, thrombocytopenic and neutropenic. You do a BM and realize this 5 yo has ALL and can see nucleoli. what are the markers for B adn T involvements
|
B- better prognosis, more common. CALLA (CD10), TdT, CD19
T- TdT, CD any less than 10. worse prognosis |
|
whats the most common cancer in kids
|
ALL
5 yo, male >female B is better prognosis, T is worse t9:22 cure is like 90% |
|
what are the clinical and lab features and prognosis of pre T lympboblastic neoplasia, is it leukemia or lymphoma

|
ALL
TdT + blasts on smear also young kids get it, common, get better will have CALLA- CD10 or CD19 |
|
in what leukemia is t9:22 seen, is this good
|

other bads: being older than 15, T cell lineage Good: hyperploidy, young, B cells affected. 90% remission :) |
|
in ALL is the BM hypercellular or hypocellular
|
HYPER! bone is tender. lots of blasts
**neoplastic blasts accumulate in BM and suppress normal hematopoiesis by crowding out the normal cells *myelopthisis* this causes peripheral blood to be...1. anemic, 2. neutropenic, 3. thrombocytopenic |
|
what are hte sx of the Acute leukemias (ALL, AML)
|
abrupt onset

A 7 y/o boy presents to your office c/o easy
fatigability. g y His mother also tells you that she has noticed that his gums bleed when he brushes his teeth. There are no specific abnormalities on physical examination Hb 10.5 gm/dL 11.5‐14 WBC 75,000 μL 5,000‐10,000 • Chest x ray mediastinal mass You order , /μ Platelets 25,000 / μL 150,000‐450,000 x‐shows a mass. bone marrow biopsy and mediastinal biopsy BM shows blasts What stain/assay would be helpful in distinguishing atypical lymphocytes from lymphoblasts? • What is the diagnosis? • What methods are available for distinguishing between the types of acute leukemia? • What lab tests aid in establishing the prognosis • Does this patient have a leukemia or a lymphoma |
gums bleed- thrombocytopenia
anemic leukophillic 1. stain- TdT on blasts only 2. Dx: ALL, t involvement 3. distinguish ALL- young. AML- older, auer rods 4. determine prognosis with translocation. t9:22 is bad 5. both leukemia nad lymphoma. the BM is blasts and the thymus is affected |
|
AML
1. Age 2. Molecular 3. Prognosis |
1. older 15-39 (ALL was <15)

This 30 y/o male had noticed progressive
weakness for 1 month. On physical examination, the tip of the spleen was palpable. There was also sternal tenderness. WBC 67,000 5,000‐10,000 Hb 10.2 gm 13.5‐16 Hct 30.6% 42‐50 • Blasts with cytoplasmic granules and Auer rods Platelets 36,000 150,000‐450,000 were noted on the peripheral smear. |
Hb/Hct- anemic
Platelets- low BLASTS- means leukemia til proven otherwise, auer rods are AML |
|
this is a cancer that ppl get when they are 30 (15-40). There are blasts that accumulate in BM and cause pancytopenia. Often this is due to a translocation. What do you think it is. how can we be sure
|
acute MYELOGENOUS leukemia
**auer rod and myeloperoxidase + **affects BM most |
|
what is the prognosis of the different classificaitons of AML
|
1. AML with myelodysplasia like features is a poor prognosis. 5q 7q 20a aberrations
2. AML that is related to therapy is VERY poor prognosis |
|
AML classification
1. M0 2. M1 3. M2 4. M3 whats most aggressive, whats most common |
classificaiton depends on maturation of PMN
M0- CD34, minimal differntiated. MOST aggressove M1- AML w/o maturation. myeloperoxidase +, few auer rods M2- AML- blasts with auer rods, myeloperoxidase +. MOST COMMON M3- DIC, t15:17, myeloperoxidase +, auer rods, treat with retinoic acid to prevent DIC |
|
what type of AML (classification) can cause DIC but is treated with retinoid acid to prevent DIC
|
M3
this is called acute promyelocytic leukemia) |
|
Acute promyelocytic leukemia (m3, AML)
clinical lab |
auer rods, can have DIC adn bleed.

This 52 y/o male had gradually increasing fatigue g together with discomfort in the left upper quadrant. Physical exam revealed an easily palpable spleen and liver edge.
• WBC 46,000 Platelets 754,000 • Hb 13.2gm Hct 39.6% • Diff: segs 46%, bands 11, metas 10, myelos 3, pros 2, eos 9, monos 2 , lymphs 17 1. dx 2. CBC 3. key things from case 4. what will the genes/ID agenst be |
1. CML- chronic myelogenous leukemia
2. Leukocytosis- left shift, thrombocytosis, anemia 3. any age, splenomegaly, leukocytosis with left shift, anemic. plates will be up or down **LAP low, t 9:22, BCR ABL |
|
what is the msot common chronic myeloproliforative disease
|
CML
**any age, splenomegaly, granulocytosis with L shift (even eos and baso increased) anemia, t9:22, BCR ABL. Long remission when treated with RTK inhibitor |
|
BCR able
t 9:22 |
CML- LAP also low
**9:22 translocation also seen in ALL and is a BAD prognostic marker |
|
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 |
|
in what leukemia will imatinib be useful
|
CML- the RTK inhibitor turns off the signaling

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)
*hypercellular BM bc of increased hematopoiesis **splenomegaly **splenomegaly- extramudullary hematopoiesis |
|
what are some common type of MPD
|
CML
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 20g/dL (nl 12‐15.6), platelet count is 550,000/μL (150,000‐450,000) and WBC 31,000/μL (5,000‐10,000). 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 |
|
whats the lab in polycythemia vera
Hgb Hct Plasma volume WBC Platelets LAP EPO other |
Hgb high
Hct high Plasma volume high WBC high Platelets high LAP normal (low in CML, another MPD) EPO LOW other: JAK mutation |
|
what is essential thrombocytosis
|
its a myeloproliforative disorder
its high platlets with no cause (not a JAK mutation as in PCV) *dx of exclusion, reactive thrombocytosis is in the ddx **can live a long time with this |
|
what are some common causes of reactive thrombocytosis
|
common!
**its anything that will increase acute phase protein: fever, bleed, surgery, infection/inflammation, Fe deficit anemia, solid tumors |
|
describe primary myelofibrosis (its a myeloproliforative disease)
clinical lab morphology |
fibrosis of BM bc there are cancer megakaryocytes that release PDGF and TGFb which are profibrosis
1. Clinical: extramedularry hematopoeisis, splenomegaly, fatigue, weight loss, night sweats, lots of infections, bleeding, can turn to AML 2. Lab 3. Morphology: nRBC, tear drop, Howell Jolly body |

A 38 y/o painter has a 2 mon. history of
worsening headaches, fatigue and abdominal pain. On exam, he has gray discoloration at the gingival margin of his teeth. Hemoglobin is 9 gm/dL (nl 13.7‐17); MCV 67 (80‐100); serum creatinine is 3 mg/dL (nl <1.2). Occasional normoblasts with basophilic stippling (pictured) Are seen in the peripheral smear. To what environmental toxin has he been exposed? What accounts for the increased creatinine? What findings might appear in a similarly exposed child? |
smear- nRBC with stippiling
**inhibit Fe from getting into hemme. inhibits ferrochelatase and ALAdehydrotase 1. Pb- lead based paint!! Pb- PlumBer 2. Renal injury 3. Kids- brain affected, bones affected more |
|
who is at risk for Pb exposure
|
1. painter
2. plumber 3. battery makers 4. radiator repair 5. Air 6. water- plumbing 7. lead glazed ceramics 8. food, toys, candy wrapper 9. gun ppl **the "natropaths" use this as tx **store it in bone/teeth, 30 year half life |
|
what is the pathogenesis of Pb (lead) toxicity
|
inhibits ferrochelatase: and gamma ALA dehydrogenase: now fe and be added to heme
interferes with epiphyseal remodling in kids, wont let fractures heal |
|
what inhibits gALA dehydrase adn ferrochelatase
|
Lead- messes with Ca so kids growth plates affected and inhibits healing of fractures
**we get RBC hemolysis, renal damage and HTN |
|
what enzymes in heme synthesis are blocked by Pb
|
1. gamma ALA dehydrase
2. Ferrochelatase |
|
what are the consequences of Pb exposure
|
Brain, Blood, Bone all bc of Ca
Anemia- hypochromic, microcytic (Fe deficit bc the enzymes are blocked) Basophillic stippling *basophilic stippling (hypochromic microcytic anemia, looks like Fe dificit anemia.. BC IT IS! recall Fe cant be inforporated into heme) |
|
13 month old Bianca Mesa was found tobe to have a microcytic anemic during a regular checkup.
1. What are the causes of microcytic anemia? Serum iron was increased. Blood lead level was elevated. • State health department worker helped parents identify the 15‐piece set of clay‐based traditional pottery from which the child had been fed. |
1. causes of microcytic anemia: Fe deficit, chronic disease, a/b thalassemia, sideroblastic anemia
in this case it was Pb exposure |
|
consequence of Pb exposure
1. Blood 2. Brain (adult and kid) 3. Peripheral Nerves 4. GI 5. ABD 6. Reproductive 7. bones |
1. Blood: microcytic anemia, basophillic anemia
2. Brain (adult and kid) : adult, HA, memnor loss. Kid- retard, encephalopathy 3. Peripheral Nerves- demyelin 4. GI- renal, HTN 5. ABD- pain, anorexia 6. Reproductive- delayed puberty, infertility 7. bones- epuphyseal plates bad, delayed healing of fracutres |
|
in what mcrocytic anemia is the TIBC (transferrin)increased
|
total iron binding capcaity is INCREASED in Fe defict anemia
**Fe is deficit so we have a higher capacity to bind in all other microcytic anemias (Chronic disease, thalassemai, sideroblast) its decreased or normal |
|
for Fe deficit anemia what is
1. Serum Fe 2. TIBC 3. % saturation 4. Ferririn 5. "other" |
1. Serum Fe: down
2. TIBC: up (the only one) 3. % saturation: down 4. Ferririn: down 5. "other": down marrow Fe **Chronic disease is the same but a DECREAESD TIBC, and INCREAED FERRITIN. Chronic disease increases Fe |
|
for a and b thal what is
1. Serum Fe 2. TIBC 3. % saturation 4. Ferririn 5. "other" |
1. Serum Fe N
2. TIBC N 3. % saturation N to high 4. Ferririn: N to high 5. "other" |
|
what is Fe like for sideroblastic anemia or Pb
1. Serum Fe 2. TIBC 3. % saturation 4. Ferririn 5. "other" |
1. Serum Fe up
2. TIBC down 3. % saturation up 4. Ferririn up 5. "other"ringed sideroblasts, basophilic stippling |

liver and spleen are HUGE
Langerhans cell histiocytosis Lots of Eos and birbeck granules |
|
what is eos granuloma
where are they found what do they do |
langerhans with eos, lymphs, plasma, and PMN
found in bone, medullary cavity, ribs, femur also have leision in skin, sotmach, lungs of smokers **common in kids, regress on their own or need to be cut out. good prognosis |
|
whats dyscrasia

abnormal material in blood
plasma cell neoplasm |
|
what is monoclonal gammapathy
|
its M protein, NOT the same as IgM
seen in plasma cell neoplasm |
|
what is the defining feature of plasma cell neoplasm
what are the common B cell ones: |
**terminally differentiated B cells secrete monoclongal Ig, excess heavy or light chains can also be produced
MM, lymphoplasmacytic lymphoma, heavy chain disease, primary immunocyte associated amyloidosis, Monoclonal Gammopathy of Undetermied Significance (MGUS) Common: follicular, large B, MGUS |
|
Case History # 24 A 69 year old female was admitted with
intractable low back pain, lethargy and confusion Albumin 2.7 (3.5‐6) Uric Ac 8.5 (2.2‐6.7) T.Prot 10 (6‐8.5) LDH 238 (<190) Ca++ 13 (8.5‐10‐5) Phos 4.1 (2.5‐4.5) BUN 42 (7‐25) T.Bili 0.8 (<1.2) Creat 2.3 (<1.2) Chol 145 WBC 4000 (5000‐10,000) Hb 10.2 (13.5‐ 16gm) Hct 30.6% MCV 106 (80 100) 230 80‐Platelets 97,000 (150,000‐450,000) Peripheral smear shows Rouleaux formation Diff: 54% segs, 2 bands, 1 meta, 33 lymphs 6 monos, 3 eos, 1 baso • 1+ aniso, 1+ micro, rouleaux formation • 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
|
malignant plasma cell in the BM (seen in MM) it has the Russel body Ig inclusion
|
|
Be able to recognoze a Mott Cell with Russel body
|
malignant plasma cell with Ig inclusions seen in MM
**really blueish/purpleish and can he binucleate |
|
clinical features of MM
|
*really common BM tumor
1. oler ppl 2. black ppl 3. can be from MGUS 4. Bone pain- low back, fracture 5. Hypercalcemia- confusion weakness 6. infections- too many Ig of one type, the body thinks you have lots so other B cells dont make AB 7. renal- bence jones 8. amyloid 9. hyperviscocity 10. Rouleaux RBC |
|
how to make Dx of MM
|
1 M protein on electrophoresis- lots og IgG, IgD, light chain (NOT IgM)
2. Bence Jones in pee 3. Rouleaux RBC in peripheral smear Officially: plasmacytosis in B< >10% monoclonal AB in serum or pee CRAB- hypercalcemia, renal insuffiency, anemai, bone leision |
|
whats a CRAB?
|
MM- your bones HURT
C- hyperCALCEMIA R- Renal Insifficiency- Bence Jones A- Anemia (reauleaux) B- Bone leision **for MM dx you need: BM plasmacytosis >10% Monoclonal AB CRAB |
|
• A 69 y/o female was admitted with intractable low
back pain, lethargy and confusion. • Chemistries T. Prot 10 H (6‐8.5) Ca++13 H (8.5‐10.5) • Creat 2.3 H (<1.2) • Hb 10.2 (12‐14gm); rouleaux formation Dx How is Dx made |
Dx: MM- bone pain, confision from hypercalacemia, anemic, renal problems. ROULEAUX (other buzzwords- bence jones, russel body)
Dx is made based on: 1. Protein electrophoresis M proteion. Lots of monoclonal AB (IgG often) 2. BM biopsy- russel body in Mott cell 3. at least one CRAB- hypercalcemia, renal insuffiency (bence jones), anemia, Bone leision |
|
A 76 y/o female presents with fracture of
her right arm without trauma. • Two years earlier, she suffered from compression fractures of the vertebra with lytic lesions on x‐ray. • Bone marrow demonstrated 36% atypical plasma cells. There was Bence Jones proteinuria and IgG paraproteinemia of plasma. Diagnosis? What supports this diagnosis? |
MM
Old, compression fracture- lytic bone problems (IL6 osteoclast activity) Atypical Plasma cells- Mott cell with russel body Bence Jones- renal insuffiency IgG |
|
when does solitary plasmacytoma predispose for MM, what are the locations
|
Solitary Plasmacytoma- localaized plasma tumor
**can happen in BM and get MM in like 10 years |
|
whats MGUS (monoclonal gammapathy uncertain significance)
|
its when you have M proteion but NO sx of MM (No CRAB)
**its a precancer that can turn into MM |
|
72 year old woman hospitalized because of
easy fatigability and blue‐red fingertips. No history of malar rash, solar‐induced rash. • On physical examination, she exhibits mild palor and questionable scleral icterus. • Lab: • Hemoglobin 8.2 gm • Reticulocyte count 5.2% ( normal ~ 1%). • Positive direct antihuman globulin (Coombs) test. |
Raynauds phenomena- cold agglutinin disease
|
|
what is the neoplasm with monoclonal IgM
|
Lymphoplastic Lymphoma- indolent
when you secrete lots of IgM its thick adn you get hyperviscossity called Waldenstroms macroglobulinemia **IgM is super thick! its NOT MM, recall that was IgG. also no renal failure or amyloid like was seen in MM LN are involved Autoimmune hemolyitc anemia due to cold agglutinin *IgM |
|
whats waldenstroms macroglobuinemia
|
its the super thick serum you get bc of IgM proliforation. Lymphoplasmacytic lymphoma
LN are involved Autoimmune hemolytic anemia due to cold agglutinin disease (IgM) bleeding cryoglobulinemia: ranauds |
|
72 year old woman hospitalized because of easy
fatigability and blue‐red fingertips. Hb 8.2 gm • Positive direct antihuman globulin (Coombs) test. • What is the finding of blue‐red fingers called? What are the causes of this condition? Which diagnosis is favored by the laboratory findings in this patient? |
1. ranauds
2. vascular spasm, AI disease- scleroderma, crest, cold agglutinin 3. Cold agglutinins, cryoglobulins, positive DAT, anemia |

A 35 y/o man comes to the ED with meningeal symptoms. He says he was taken to a trauma center in rural Ecuador 2 yrs. ago after experiencing blunt abdominal trauma. He does
not remember exactly what was done, but he believes they took drastic measures to control intraabdominal bleeding. Before leaving the trauma center, he was counseled about a new susceptibility to encapsulated organisms. Which of the following findings would be seen in a peripheral blood smear in this patient? A. Heinz bodies, target cells, perhaps more platelets than usual B. Megaloblastic anemia C. Schistocytes D. Sickle cells E. Spherocytes |
A- Heinz body, target cells, lots of platelets: THE SPLEEN IS GONE!!!
