ITP–Idiopathic Thrombocytopenic Purpura is an Auto-Immune disease, which causes body’s own Immune system to kill its own Platelets (Also called Thrombocytes). Platelets perform the function of clotting of the blood and eventually stop the bleeding after an injury. Now, let us talk a bit on ‘idiopathic thrombocytopenic purpura causes’.
‘Purpura’ are rashes on the skin due thinning of the blood, which has leaked out from the blood capillaries. The term ‘Idiopathic’ is suggestive of the fact that the cause is or remains unknown for the ailment. Though, the net effect of abnormally low numbers of Platelets in the body may be due a microbial infection, viral or bacterial, or more, or side effect of some medication. ITP could be Acute or Chronic, depending if it has been less than or more than 6 months. Normal platelet count of a healthy adult is 1, 50, 000 to 4, 50, 000.
Corresponding severe decrement of platelets would/could lead to internal haemorrhage, and could be fatal.
Bone Marrow examination would reveal whether such low platelet count has resulted due too little production of platelets or too much destruction of same.
(Now, a bit on our Spleen: It consists of Red Pulp, White Pulp and more. The functions would be: Formation of RBC’s (Erythrocytes) (in specific health condition), Ridding RBC’s of the waste materials, Storage site for Iron, RBC’s, Platelets and more (The Iron metabolism provides protection against Bacterial Infections), Storage and Development site for WBC’s, Phagocytosis (Engulfing and Killing) of circulating micro-organisms in the body and so on…)
