![]() Our findings suggest that an activation of coagulation including hyperfibrinolysis secondary to the endothelial damage is a typical feature of the common types of HSP. ![]() Clinicians should be aware of these laboratory findings in order not to confuse common cases of HSP with purpura necroticans, a very severe type of vasculitis in which signs of disseminated intravascular coagulation (DIC) have been reported. These findings probably reflect local reactions within inflamed blood vessels rather than a systemic activation of coagulation and hyperfibrinolysis. The pathologic values were correlated to the activity of the disease, but abnormalities were also found in milder cases of HSP. In 11 patients, plasma concentrations of thrombin-antithrombin complex (TAT) and prothrombin fragments 1 and 2 (F1+2) were examined six of them showed abnormal results. In parallel to the activity of the disease, D-dimer concentrations in plasma were found to be significantly increased in 15 of the 17 patients almost 50% of all patients showed values higher than 10 times the upper limit of the normal range.

This can disrupt normal blood flow to organs such as the kidneys and liver and can lead to organ failure. Blood clots form in small blood vessels throughout the body.

Disseminated intravascular coagulation (DIC) is a serious, sometimes life-threatening condition in which the proteins in the blood involved in blood clotting become overactive.

The first-line tests should ideally be simple, and readily and rapidly available. The disease can also cause your healthy red blood cells to fragment and break up when they travel through the small vessels that are filled with clots. Laboratory diagnosis of DIC is based on tests that demonstrate activation of coagulation and consumption of clotting factors, coagulation inhibitors and platelets. You may also have bleeding that starts spontaneously (on its own). When this happens, you may have a high risk of serious bleeding, even from a minor injury or without injury. In other cases of DIC, the clotting proteins in your blood are consumed. Lack of blood flow can damage and cause major injury to the organs. Some of these clots can clog the vessels and cut off the normal blood supply to organs such as the liver, brain, or kidneys. No single laboratory test or set of tests sensitive or specific enough to make definitive diagnosis, instead the whole clinical picture must be taken into. In some cases of DIC, small blood clots form in the blood vessels. The underlying cause is usually due to inflammation, infection, or cancer. If these proteins become abnormally active throughout the body, you could develop DIC. When you are injured, proteins in the blood that form blood clots travel to the injury site to help stop bleeding. Disseminated intravascular coagulation (DIC) is an acquired clinicobiological syndrome characterized by widespread activation of coagulation leading to fibrin deposition in the vasculature, organ dysfunction, consumption of clotting factors and platelets, and life-threatening hemorrhage. ![]()
