Thrombotic thrombocytopenic purpura (TTP) is a blood disorder that results in blood clots forming in small blood vessels throughout the body. [2] This results in a low platelet count, low red blood cells due to their breakdown, and often kidney, heart, and brain dysfunction. [1]
The 4T score for heparin-induced thrombocytopenia [9] [10] Thrombocytopenia 2 points if the fall in platelet count is >50% of the previous value, AND the lowest count (nadir) is 20–100 × 10 9 /liter 1 point if the fall is 30–50% or the nadir is 10–19 × 10 9 /liter No points if the fall is less than 30% or the nadir is <10 × 10 9 /liter ...
ICD-10 coding number Diseases Database coding number Medical Subject Headings Iron-deficiency anemia: D50: 6947: Iron-deficiency anemia (or iron deficiency anaemia) is a common anemia that occurs when iron loss (often from intestinal bleeding or menses) occurs, and/or the dietary intake or absorption of iron is insufficient. In such a state ...
X-linked thrombocytopenia, also referred to as XLT or thrombocytopenia 1, is an inherited clotting disorder that primarily affects males.It is a WAS-related disorder, meaning it is caused by a mutation in the Wiskott–Aldrich syndrome (WAS) gene, which is located on the short arm of the X chromosome. [1]
Coagulopathy (also called a bleeding disorder) is a condition in which the blood's ability to coagulate (form clots) is impaired. [1] This condition can cause a tendency toward prolonged or excessive bleeding ( bleeding diathesis ), which may occur spontaneously or following an injury or medical and dental procedures.
Platelet storage pool deficiency is a family of clotting disorders characterized by deficient granules in platelets.Individuals with these disorders have too few or abnormally functioning alpha granules, delta granules, or both alpha and delta granules and are therefore unable to form effective clots, which leads to prolonged bleeding.
Recurrent miscarriage is an indication for thrombophilia screening, particularly antiphospholipid antibodies (anti-cardiolipin IgG and IgM, as well as lupus anticoagulant), factor V Leiden and prothrombin mutation, activated protein C resistance and a general assessment of coagulation through an investigation known as thromboelastography.
The best known and most common hereditary form is Factor V Leiden, which is responsible for more than 95% of cases. [5] Other genetic causes include Factor V Cambridge (VThr306) and the factor V HR2 haplotype (A4070G mutation). [5] [6] Acquired forms of APC resistance occur in the presence of elevated Factor VIII concentrations.
