First, it has to be determined that there kdiopatik no blood abnormalities other than a low platelet count, and no physical signs other than bleeding.
PATOFISIOLOGI IDIOPATIK (IMUN) TROMBOSITOPENIA PURPURA (ITP)
Platelets are sequestered and destroyed by mononuclear macrophages, which are neither reticular nor endothelial in origin. First-line therapies for immune thrombocytopenic purpura: Nplate is an experimental treatment for stimulating platelet production.
It causes a characteristic purpuric rash and an increased tendency to bleed. Laparoscopic splenic procedures in children: In this, they differ from the previously discussed agents that act by attempting to curtail platelet destruction.
Need a Curbside Consult? In adults, it is more often a long-term chronic disease and can occur after a viral infection, with use of certain drugs, during pregnancy, or as part of an immune disorder.
Abstract Idiopathic thrombocytopenic purpura ITP is defined as a hematologic disorder, characterized by isolated thrombocytopenia without a clinically apparent cause. Other biochemical examinations, liver function tests, and ultrasonography of abdomen were normal.
At least 70 percent of childhood cases will end up in remission within six months, even without treatment. Long-term salvage therapy with cyclosporin A in refractory idiopathic thrombocytopenic purpura. FDA extends use of Promacta in young children with rare blood disorder. However, since the diagnosis depends on the exclusion of other causes of a low platelet count, additional investigations such as a bone marrow biopsy may be necessary in some cases.
Patients are also advised to avoid using aspirin or ibuprofen as pain relievers because these drugs lengthen the clotting time of blood. Diseases of clotting D50—69,74— New cases of chronic refractory ITP comprise approximately 10 cases per 1, per year.
Bone marrow examination may be performed on patients over the age of 60 and those who do not respond to treatment, or when the diagnosis is in doubt. Cooper N, Bussel J.

In immune thrombocytopenic purpura ITPan abnormal autoantibody, usually immunoglobulin G IgG with specificity for one or more platelet membrane glycoproteins, binds to circulating platelet membranes. The major causes of accelerated platelet consumption include immune thrombocytopenia, decreased idiopatiik marrow production, and increased splenic sequestration.
Jayachandranand Khushboo Singh. Management of immune thrombocytopenia–something old, something new. Romiplostim for the treatment of chronic immune idiopathic thrombocytopenic purpura. Relative marrow failure may contribute to this condition, since studies show that most patients have either normal or diminished platelet production.

In chronic refractory cases, where immune pathogenesis has been confirmed,  the off-label use of the vinca alkaloid    and chemotherapy agent vincristine may be attempted. A report of 66 cases. Pediatr Rev ; An analysis for anti-platelet antibodies is a matter of clinician’s preference, as there is disagreement on whether the 80 percent specificity of this test is sufficient to be clinically useful.
Biopsy is performed before splenectomy to evaluate for possible hypoplasia or fibrosis. It should be idiopatuk in duration unless demonstrated that symptomatic thrombocytopenia persists.
Thrombopoietin receptor agonists ie, eltrombopag, romiplostim may maintain platelet counts at safe levels in adults with chronic ITP refractory to conventional medical management or splenectomy. Received salary from Medscape for employment. Eltrombopag for the treatment of chronic idiopathic thrombocytopenic purpura. ITP has no cure, and relapses may occur years after seemingly successful medical or surgical management. ITP is an autoimmune disease with antibodies detectable against several platelet surface antigens.
Practice Essentials Immune thrombocytopenic purpura ITP is a clinical syndrome in which a decreased number of circulating platelets trombositopeni see the image below manifests as a bleeding tendency, easy bruising purpuraor extravasation of blood from capillaries into skin and mucous membranes petechiae.
Vascular complications after splenectomy for hematologic disorders. Acute ITP often follows an acute infection and has a spontaneous resolution within 2 months.
In the United States, the adult chronic population is thought to be approximately 60,—with women outnumbering men approximately 2 to 1, which has resulted in ITP being designated an orphan disease. Immune thrombocytopenic purpura ITP.
