Definitions
- the present invention relates to a method for grasping a disease state of disseminated intravascular coagulation (hereinafter referred to as DIC).
- DIC disseminated intravascular coagulation syndrome
- the essential feature of DIC is the force in the formation of microthrombus due to the pathological and persistent activity of the blood coagulation system, and the fibrinolytic system is activated accordingly.
- the balance between the two differs depending on the underlying disease or case, and there are cases where the coagulation activity is significant but the fibrinolytic system is suppressed, or the activity of both coagulation and fibrinolysis is significant. It is done.
- the former is classified as the solidification dominant type and the latter as the fibrinolysis dominant type.
- Coagulation-dominated DIC is prone to organ symptoms as a clinical manifestation that often accompanies infections, particularly sepsis.
- DIC fibrinolysis-dominated DIC
- 3D FDP Fibrin degradation product
- PI Plasmin / plasmin inhibitor complex
- the underlying disease is acute promyelocytic leukemia.
- DIC is a highly urgent pathological condition for which early diagnosis and early treatment are desired because DIC leads directly to death if treatment is delayed.
- DIC is diagnosed according to the DIC diagnostic criteria of the Ministry of Health and Welfare. According to this diagnostic criteria, 1) presence or absence of organ damage, 2) platelet count, 3) FDP, 4) fibrinogen, 5) PT ratio (prothrombin time ratio) values are scored to determine DIC.
- This diagnostic standard is excellent for the definitive diagnosis of DIC.
- There are difficulties in early diagnosis of DIC, and clinical treatment according to this diagnostic standard has already caused the pathological condition of DIC to be too advanced and too late.
- DIC As a treatment method for DIC, low molecular heparin and antithrombin III preparations are administered in order to suppress the frequent occurrence of thrombus in the blood vessel and at the same time prevent the progression of consumable coagulation disorder.
- fibrinolytic DIC gabexate mesylate with antithrombin and antifibrinolytic effects is administered. Platelet supplementation with concentrated platelets is essential for DIC associated with blood disorders with reduced platelet count production.
- DIC with low blood fibrinogen is treated with fresh frozen plasma (FFP) infusions.
- FFP fresh frozen plasma
- TTP like DIC and HUS, shows a pathological condition called microangiopathic hemolytic anemia (MAHA).
- MAHA microangiopathic hemolytic anemia
- DIC is composed of the main component fibril of microthrombus that reduces the inner diameter of the blood vessel
- TTP or HUS is composed of platelets.
- TTP was reported for the first time in 1924 by Moschcowitz in the United States, with small arteries clogged with platelet aggregates (platelet thrombus). It is a serious disease. Symptoms are 1) thrombocytopenia (purpura on the skin), 2) hemolytic anemia (due to erythrocyte collapse), 3) renal dysfunction, 4) fever, 5) swaying neuropsychiatric symptoms.
- VWF-cleaving protease VWF-cleaving protease
- AD AMTS 13 AD AMTS 13
- TTP blood plasma
- vWF multimer Large vWF multimer is not decomposed and causes excessive platelet aggregation due to high shear stress generated in microvessels, etc., and clogs blood vessels with thrombus.
- Patent Document 2 discloses a method for detecting the degree of thrombosis tendency or thrombosis characterized by quantifying ADAMTS13.
- thrombosis acute or chronic bone marrow is disclosed.
- Leukemia acute promyelocytic leukemia, systemic lupus erythematosus, pulmonary embolism, cerebral embolism, central hepatic vein occlusion, acute lymphocytic leukemia, thrombotic microangiopathy, thrombotic thrombocytopenic purpura, hemolytic uremic Syndrome or deep vein thrombosis.
- Patent Document 3 discloses DIC or systemic inflammatory response syndrome (.systemic inflammatory response synarome;; 5lRS) that analyzes ADAMTS13 and Z or degradation factors thereof (for example, elastase, plasmin, or thrombin).
- DIC or systemic inflammatory response syndrome (.systemic inflammatory response synarome;; 5lRS) that analyzes ADAMTS13 and Z or degradation factors thereof (for example, elastase, plasmin, or thrombin).
- ADAMTS13 activity is slightly decreased or normal.
- the etiology in this case is diverse, with congenital and acquired factors.
- the former is due to genetic abnormalities such as plasma factor factor H (Factor H), which has a complement-regulating action, and CD46, a vascular endothelial transmembrane protein.
- Factor H plasma factor factor H
- CD46 a vascular endothelial transmembrane protein
- TTP is a very rare disease, and is a force that is commonly acquired. As described below, there are rare cases where TTP occurs based on a congenital predisposition.
- Clinical symptoms of TTP include diarrhea due to ischemic enteritis, abdominal pain, bloody stool, neurological symptoms such as convulsions, visual impairment, and renal impairment.
- Laboratory findings include changes associated with hemolysis, such as clotted red blood cells of the terminal blood due to thrombus formation, anemia, thrombocytopenia, serum LDH (lactate dehydrogenase), indirect bilirubin rise, and haptoglobin fall. Serum due to kidney damage There is also an increase in creatinine.

In addition, as shown in the examples described later, among the first group to the third group, the first group and the second group are ⁇ DIC patient groups to be diagnosed with TTP '', and the third group is ⁇ What is TTP? An unrelated group of DIC patients.
