Antiphospholipid antibody syndrome is a hematologic disorder in which the main symptom is the formation of blood clots in small and medium-sized vessels with antiphospholipid antibodies in the blood. Both arteries and veins have the possibility of forming thrombosis, but venous thrombosis is more probable. 1.Type: Antiphospholipid antibody syndrome can be divided into two types, one is primary and the other is malignant. Primary symptoms are mild and do not cause death in a short period of time. In contrast, malignant symptoms are more severe and within days to weeks, a large number of blood clots are formed that spread throughout the nerves, kidneys, lungs and other organs, leading to organ failure and then death. 2. Symptoms: The most common symptom is the formation of blood clots. Blood clots can be formed in the blood vessels of any part of the organ. Usually, blood clots are formed only in a certain area. Sometimes when a large thrombus forms, there is a decrease in antibody titer. Patients may also develop moderate thrombocytopenia. Spontaneous abortions occur in pregnant women. 3. Treatment: The treatment of this disease is based on anticoagulation and antiplatelet, and the commonly used drugs are aspirin and heparin. When doing antithrombotic treatment, antiplatelet aggregation drugs, heparin and other drugs are commonly used. Glucocorticoids, immunosuppressants, immunoglobulins and other drugs are also applied for treatment, and even blood purification therapy is applied. Therefore, antiphospholipid antibody syndrome is a relatively serious disease, and patients should go to the hospital as soon as possible to avoid delaying the disease and aggravating it.
