**PLATELET DISORDERS Immune(Idiopathic) Thrombocytopenic Purpura ITP -Is defined as isolated low platelet count (thrombocytopenia) with normal bone marrow and the absence of other causes of thrombocytopenia -Causes : .lymphoma .CLL .HIV .connective tissue disease .autoimmune condition -Symptoms & Signs : .bruises (purpura) .petechiae (tiny bruises), especially on the extremities .bleeding from the nostrils and/or gums .menorrhagia (excessive menstrual bleeding) -Treatment : .corticosteroids .intravenous immunoglobulin .anti-D immunoglobulin . immunosuppressive drugs
Von Willebrand Disease vWD -An increased predisposition to platelet type bleeding from decreased amount of von willebrand factor -Is the most common hereditary coagulation abnormality described in humans, although it can also be acquired as a result of other medical conditions -Types of hereditary vWD : .vWD Type I (M.C type- Asymptomatic) .vWD Type II .vWD Type III -Symptoms : .bleeding tendency(bruising,nosebleeds and bleeding gums) .women may experience heavy menstrual periods and blood loss during childbirth. .severe internal or joint bleeding is uncommon (except for in vWD type III) -Diagnosed by bleeding time (normal bleeding time 3-8min)
**CAGULOPATHY Hemophilia A and B -Hemophilia A (factor 8 deficiency) -Hemophilia B (factor 9 deficiency)(christmas disease) -Both hemophilia (A & B) are X-linked recessive diorders resulting in males -Symptoms : .prolonged bleeding after circumcision (during surgical procedures or with trauma) .bruise .hemarthrosis (M.C),hematoma,GI bleeding .bleeding in joints (ankle,knee and elbow) .blood loss in iliopsoas muscle .life threating bleeding (intracranial-GI bleeding) -Causes of prolonged PT or PTT : .prolonged PT (factor 7 deficiency,liver disease,vit K deficiency,warfarin use) .prolonged PTT (factor 8-9-11-12 deficiencies,heparin use,antiphospholipid anti body) .prolonged PT and PTT (factor 1-5-10 deficiencies,pathrombin,fibrinogen,vit K deficiency,liver disease,DIC,compined heparin and warfarine ise) -Labs : .inc. PTT (2-3)X / normal PT,INR,platelet,vWF -Treatment : .DDAVP (desmopressin) .prophylaxis is recom. .AVOID (anti-platelet,aspirin) .desmopressin does not work for hemophilia B
Vitamin K Deficiency -The deficiency of vit K resulting in dexreased production of factors (2-7-9-10) -Both the PT and PTT are elevated -Causes of deficiency vit K : .dietary deficiency .malabsorption .antibiotics that kill the bacteria in the colon that produce vit K
Liver Disease -Coagulopathy from the decreased production of clotting factors be the liver -All factors produce in liver EXCEPT (8) and (vWF) -Factor 8 produced in endothelia cells -Treatment : .fresh frozen plasma or cryoprecipitate + To stop bleeding in hemophilic baby you have to give (Cryoprecipitate)
