What Is Bleeding Diathesis?
Hemorrhagic diathesis, also known as hemorrhagic tendency, is a group of diseases that are difficult to stop after spontaneous bleeding or injury caused by hemostatic dysfunction, or that hemostasis and coagulation are significantly delayed.

- Hemorrhagic diathesis, also known as hemorrhagic tendency, is a group of diseases that are difficult to stop after spontaneous bleeding or injury caused by hemostatic dysfunction, or that hemostasis and coagulation are significantly delayed.
- A pathological condition that causes bleeding under the skin, mucous membranes, and other parts of the body due to natural or very minor trauma. The main symptoms of hemorrhagic quality are purple spot disease, necrosis and hemophilia. In addition, infectious diseases, leukemia, cachexia, uremia, poisoning, liver disease, etc. may also have this symptom. Some are due to congenital anomalies; some are symptomatic. According to its pathogenesis, some are due to pathological changes in the blood, and some are due to permeability disorders of the blood vessel wall. For the clinical diagnosis of hemorrhagic quality, it is necessary to check five factors such as blood vessel wall, platelets, coagulation factors, anticoagulation factors, and fibrinolysis.

- Hemorrhagic purpura
- Vascular hemorrhagic quality disease. Mainly found in horses, also known as blood spot disease; occasionally seen in cattle and pigs, such as bovine hemorrhagic septicemia, rhinoceros poisoning, swine fever, swine fever and so on. The cause of equine blood spot disease is not fully understood. It is generally believed to be caused by streptococcal infection of the upper respiratory tract, and the blood vessel produces an allergic reaction to streptococcal protein. , Equine infectious rhinopneumonia and other complications. Systemic edema and bleeding are most typical in the head, but do not occur in the forelimbs from the wrist and below the sacroiliac joints. There is no fever or pain in the edema. Serum may leak from the skin in severe cases. Hemorrhage leads to submucosal stasis spots, mainly on the nasal, oral mucosa, and conjunctiva. Because there is no significant change in platelet count, it can be distinguished from equine thrombocytopenic purpura. Treatment can try blood transfusion, injection of adrenal corticosteroids and other drugs.
- hemophilia
- A recessive linked hereditary disease caused by insufficient blood coagulation-activating enzymes. It is mainly found in horses and dogs. The lack of anti-hemophilic globulin coagulation factor is a cause of insufficient blood coagulation-activating enzymes. Hemophilia type A is caused by the transmission of sex-linked genes through the first generation of mares (phenotype heterozygous individuals) to the second generation of stallions (genotype homozygous individuals). It occurs due to the lack of coagulation-activating enzyme components (PTC, factor IX) or coagulation-activating enzyme precursors (PTA, factor XI). It is called type B or C hemophilia. Type A cases have been found in British thoroughbred and standard horse foals; type B and C cases have been found in Arabian horse foals. After contusion, multiple hematomas are often present; after minor trauma, bleeding often does not stop. Except that the clotting time can be extended to several hours, everything is normal. Try ovarian hormones, transfusion of whole blood, and medications that increase blood clotting. Preventive measures are to eliminate breeding animals with hemophilia in breeding.
