Thrombotic thrombocytopenic purpura (TTP) initially presents with a range of symptoms that may include severe thrombocytopenia (platelet count usually < 30,000/mm³), microangiopathic hemolytic anemia (evidenced by schistocytes in the blood smear), and various clinical signs such as petechiae, purpura, neurologic symptoms, myocardial ischemia ...
Among patients with Evans syndrome, the prevailing causes of death were bleeding, infections, and hematological cancer. [ 4 ] It has been observed that there is a risk of developing other autoimmune problems and hypogammaglobulinemia , [ 30 ] in one cohort 58% of children with Evans syndrome had CD4-/CD8- T cells which is a strong predictor for ...
Fetal blood sampling is estimated to cause death of the baby in 1.3% of procedures, however the incidence varies significantly from center to center. [22] With an overall risk of death of the fetus due to the repeated procedures of about 3% (17 deaths out of 485 pregnancies). [9]
One common definition of thrombocytopenia requiring emergency treatment is a platelet count below 50,000/μL. [5] Thrombocytopenia can be contrasted with the conditions associated with an abnormally high level of platelets in the blood – thrombocythemia (when the cause is unknown), and thrombocytosis (when the cause is known).

Congenital amegakaryocytic thrombocytopenia (CAMT) is a rare autosomal recessive bone marrow failure syndrome characterized by severe thrombocytopenia, which can progress to aplastic anemia and leukemia. [4] CAMT usually manifests as thrombocytopenia in the initial month of life or in the fetal phase.
Immune thrombocytopenic purpura (ITP), also known as idiopathic thrombocytopenic purpura or immune thrombocytopenia, is an autoimmune primary disorder of hemostasis characterized by a low platelet count in the absence of other causes. [1] [2] ITP often results in an increased risk of bleeding from mucosal surfaces (such as the nose or gums) or ...
Purpura fulminans is rare and most commonly occurs in babies and small children [25] but can also be a rare manifestation in adults when it is associated with severe infections. [26] For example, Meningococcal septicaemia is complicated by purpura fulminans in 10–20% of cases among children. [ 27 ]
Kasabach–Merritt syndrome (KMS), also known as hemangioma with thrombocytopenia, [1] is a rare disease, usually of infants, in which a vascular tumor leads to decreased platelet counts and sometimes other bleeding problems, [2] which can be life-threatening. [3] It is also known as hemangioma thrombocytopenia syndrome.
