Anemias and Hemorrhagic Disorders
β£
- Hypochromic + microcytic anememia (might be normocytic initially)
- low serum iron
- low ferritin
- incr. TIBC + Transferrin
- Normal/Low Reticulocytes
- Thrombocytosis
- high RDW
- π¦΄-marrow β Absent iron reserves (Perl's stain)
β£
- Has to present decreased MCV and MCH Values in the complete blood count
- Can be a Thalassemia, Anemia of a chronic Disease, Iron deficiency anemia or sideroblastic anemia
β£
- Low serum iron
- Low TIBC
- Normal/high ferritin (elev. due to inflammation) -associated with elevation in acute phase reactants (ESR, CRP, fibrinogen, platelets)
β£
Heterozygotes (minor beta talassemia)
- normal clinical status
- mild pallor
- hepatosplenomegaly (HSM)
Homozygotes (major beta talassemia)
- growth retardation
- bone deformeties - short limbs, mongoloid facies
- intense pallor, jaundice + melanodermia (pseudo-tanned)
- HSM
- Iron overload! β organe dmg (HF, LF, hypogondism, DM,RF)
β£
- severe microcytic anemia
- target cells, basophilic inclusion
- teardrop cells
- Erythroblasts in periph blood
- indirect hyperbili
- normal-high iron, ferritin, transferrin
- Perls stain β incr. hemosiderin in target organs
- low RDW
- Electrophoresis! β low HbA1, incr. HbA2 + HbF
β£
Hereditary: Bernard-Soulier (Gp1b), Glanzmanns (G2b-3a), storage pool disease, (vWD if associated with FVIII); or vWD Type 2
Acquired: drugs (NSAIDS, ASS), Uremia, myeloproliferative disorders
β£
- Splenomegaly due to:
- TTP, Hemolytic Uremic Snd, Heparin induced Thrombocytopenia, DIC
- ITP β Idiopathic + secondary
βidiopathic children; second. adults
β£
- idiopathic: auto-AB platelet destruction
- secondaryβAntibiotics, Lupus, Aids, Hep C
- classic clinical picture:
- petechia, echymosis, purpura
- epistaxis
- gum bleeding
- no splenomegaly
MUCO-CUTANEOUS BLEEDING
β£
- Steroids (1-2mg/kg)
- Splenectomy (if no response to steroids)
- IVIG
- Thrombopoietin receptor agonist (Eltrombopag + Romiplostim)
β£
- abrupt onset
- mucocutaneous bleeding
- pallor
- jaundice
- thrombotic events (cerebral, cardiac)
- neuro-psychiatric symptoms
- renal failure
LAB
- thrombocytopenia
- hemolytic anemia
- reticolocytosis
- Schisocytes (red helmet cells)
- BUN+Crea elev.
- Low ADAMTS13 + AB
β£
- muco-cutaneoal bleeding (esp. Ear-nose-throat)
- prologend BT
- normal PT + APTT (β APTT high if low FVIII)
- low vWF
- Ristocetin cofactor activity β neg. in vWD
β£
Hemophilia A β FVIII
Hemophilia B β F IX
deep bleeding:
- hemarthrosis (knee, shoulder, elbow, hip)
- hematomas
- hematuria
severe βspontaneous hemorrh (<1% residual factor)
medium β after minor trauma (1-5%)
mild β after trauma or surgery (5-25%)
β DG
- incr. APTT
- normal PT, ThrombinT, BT
β£
Causes:
"STOP Making Trouble"
- infections (sepsis)
- trauma
- Obstetric complications
- Pancreatitis
- malignancies (acute leukemia)
- Acute hemolytic transfusion reaction
Lab:
- increased aPTT, PT + bleeding time
- high D-DImers,
- low Fibrinogen
- Thrombocytopenia
- Schistocytes
β£
