Anemia Flashcards
Not a disease defined as the decrease below normal or one or more
Anemia
rare but potentially deadly bone marrow failure syndrome
Aplastic anemia
most frequently implicated drug in aplastic anemia
Chloramphenicol
asso. w/ identified cause, some of the causes include chemicals and viruses/ drugs
Secondary Acquired Aplastic Anemia
most common of the inherited aplastic anemia
Fanconi Anemia
What are the physicl abnormalities include in Fanconi Anemia
Skeletal Abnormalities
Skin pigmentation
Short stature
Abn. eyes, kidney and genitals
Hyperpigmentation, Hypopigmentation, cAFE-AU-LAIT LESIONS
Physical abnormalities in Fanconi anemia asso. w. skin pigmentation
Thumb malformation, Microcephaly, Scoliosis
Physical abnormalities in Fanconi anemia: Skeletal abn.
PNH is also known as
Marchifava-Micheli Syndrome
It is caused by deficiency of DAF (CD 55) and MIRL (CD 59)
PNH
Confirmatory test for PNH
Flow cytometry
Tests for PNH
Ham’s Acidified Serum Test
Sugar water Test
Flow Cytometry
examples of complementary regulatory proteins
DAF
Membrane Inhibitor of Reactive Lysis (MIRL)
Most common anemia among hospitalized patients, Ass. w/ chronic infxn, body store have abundant Iron
Anemia of Chronic Inflammation
Central feature of ACI
Sideropenia (Decreased serum iron)
Acute phase reactants that contribute to ACI
Hepcidin
Ferritin
Lactoferrin
Master regulatory hormone for systemic iron metabollism inactivates FERROPORTIN
Hepcidin
Transport iron from Tissue to the Blood
Ferroportin
develop when the production of Protoporphyrin or the incorporation of iron into Protoporphyrin is Prevented; iron is trapped in the Mitochondria
Sideroblastic Anemia
NCULEATED RBC precursor w/ Cytoplasmic Iron Granules
Sideroblast
ANucleate RBC w/ Iron granules
Siderocyte
ANucleate RBC w/ Iron granules
Siderocyte
Hallmark of the Sideroblastic Anemia
Ring Sideroblasts
Most common anemia, caused by Blood loss/ Nutitional def/ ^ iron demands/ Malignancies of GI tract/ Hookworm Infxn
IDA
spooning of the fingernails
Koilonychia
cravings for non-food items
Pica
craving for ICE
Pagophagia
indirectly measures the conc. of transferrin by measuring its ability to bind iron
TIBC
the first laboratory test to become abnormalwhen iron stores begin to decline; revelas the body’s tissue iron stores
Serum Ferritin
caused by the lack of intrinsic factor
V B12 deficiency
Found in the stomach produce HCI and IF
Parietal cells
a type of megaloblastic anemia caused by inadequate intake, Increased need, renal dialysis
Folate deficiency
Considered as the root cause of megaloblastic anemia
Impaired DNA synthesis
DNA synthesis is dependent on an important structure called
Thymidine Triphosphate (TTP)
VB12 is also known as
Cobalamin
Synthetic form of VB12 found only in supplements
Cyanocobalamin
naturally occuring form that may be obtained from either food sources or supplements
Methylcobalamin
loss of epithelium on the tongue results in a smooth surface and soreness
Glossitis
Laboratory test that differentiate Folate def. and VB12 Def.
holoTC assay
Other possible findings in megaloblastic anemia
‘‘TNBCH’’
Teardrop cells
Nucleated RBCs
Howell-Jolly bodies
Basophilic Stippling
Cabot rings
Metabolically active form of VB12
Holotrancobalamin
Disorders characterized by impaired synthesis of HEME, example: LEAD POISONING
Porphyrias
LEAD can inhibit enzymes in the body including
Ferrocheletase adn Pyrimidine-5-Nucleotidase
enzyme needed to completely remove the RNA remnants from reticulocyte to become mature Erythrocyte
(Kung wala ni dili ma remove ang RNA mahimong Basophilic stippling)
Pyrimidine-5-nucleotidase
