Hemato in systemic diseases
- 1. Hematological aspects in systemic diseases Dr.Tanyarat Jomgeow
- 5. Malignant diseases Hematological manifestation RBC - Anemia chronic disorders, blood loss, iron deficiency, folate deficiency, hemolysis marrow infiltration, marrow suppression from chemotherapy or radiotherapy - Leukoerythroblasic blood film (NRBC and immature granulocyte ) - Polycythemia => tumor of renal, hepatic, cerebellar, uterine
- 6. Malignant diseases Hematological manifestation WBC - Leukemoid reaction wide spread of tumor necrosis and inflammation Platelet and blood coagulation - Thrombocytosis or thrombocytopenia - Metastasis tumor => DIC, hemostasis failure
- 7. Autoimmune diseases and other connective tissue disorders Hematological manifestation RBC - Anemia , RBC agglutination, rouleaux formation autoimmune hemolytic anemia chronic disorders iron deficiency by GI bleeding associated with salicylates, anti-inflammatory drugs, corticosteroid WBC - Leukocytosis or leukopenia
- 8. Hematological manifestation Platelet - autoimmune thrombocytopenia Coagulation - lupus anticoagulant interfere blood coagulation Autoimmune diseases and other connective tissue disorders *LE, ANF/ANA positive, ESR raised
- 9. Renal diseases Hematological manifestation RBC - Anemia Chronic diseases => chronic renal failure Uremia => inhibit erythroid proliferation => burr cells Dialysis => blood loss, aluminium excess Erythropoietin HUS (hemolytic uremic syndrome) - Microangiopathic hemolytic anemia, fragmented RBC, hematuria - thrombocytopenia
- 10. Liver diseases Hematological manifestation RBC - Anemia *macrocytic anemia with target cells (increased of choresterol in membrane) *hemolytic anemia in chronic immune hepatitis * Viral hepatitis associated with aplastic anemia Coagulation Deficiency of Vit-K dependent coagulation factor (factor II, VII, IX, X)
- 11. Infection Hematological manifestation Bacteria Acute bacterial infection - neytrophil leukocytosis, toxic granulation - Dohle bodies, shift to the left of granulocyte Septicemia - severe hemolytic anemia - Leukemoid reaction - DIC
- 12. Infection Hematological manifestation Viral infection - mildly anemia (acute viral infection) - Infectious mononucleosis , atypical lymphocyte - Some patients develop PNH, TTP-HUS - Aplastic anemia may occur in viral hepatitis, EBV, CMV - Thrombocytopenia and platelet clumping
- 13. Infection Hematological manifestation Malaria - Hemolysis - DIC - Thrombocytopenia - Chronic disorder => anemia - Splenomegaly
