Does the infection cause thrombocytopenia?

Nowadays, there are more and more people suffering from thrombocytopenia, so many people are more concerned about the causes of platelets, here experts point out: infection can cause thrombocytopenia, the following is a specific introduction to the causes of thrombocytopenia caused by infection, I hope it can help patients. What causes thrombocytopenia due to infection?

Experts believe that the following reasons are the most important. (1) Immune mechanism: pathogens enter the human body, adsorb on the surface of platelets as antigens, and then bind to antibodies produced by the spleen, or the immune complex binds to platelets through platelet FC receptors, and is recognized and engulfed by macrophages in the human body, so that the destruction of platelets is more than that of normal people.

On the other hand, when the human body is infected by a virus, the number of FC or C3B receptors on macrophages increases, and the affinity increases, making platelets more easily destroyed. This is also one of the main causes of thrombocytopenia caused by infection. (2) Megakaryocyte violation:

Viruses and bacteria invade the bone marrow, and their continuous replication and toxins directly damage the proliferative and mature ability of megakaryocytes, causing their platelet-producing function to be impaired and platelet production to be reduced. (3) Causes of thrombocytopenia caused by infection: pathogens can activate platelets in the blood through the release of various toxins, aggregate and destroy, resulting in the reduction of circulating platelets.

Yes, but illness is already a fact. **Not directly related to precipitating factors.

Hello! Glad for your question!

Platelet count refers to the number of platelets contained per unit volume of blood, which are the smallest cells in the blood that protect the integrity of capillaries. High platelets are seen in physiological and pathologic elevation, physiological elevation, and are common in iron deficiency anemia and inflammatory responses. Pathologically elevated, seen in essential thrombocythemia, polycythemia vera, chronic myeloid leukemia macrocytosis, and tumor bone marrow metastases (in the presence of lytic changes).

Reactivity is also elevated after splenectomy, fractures, hemorrhage, and surgery. Cavity cheats.

Yours is the greatest support to me! Break a leg! Thank you!

If platelets increase or decrease dramatically, a disorder is suspected. Myeloproliferative diseases, acute infection, tumors and other diseases will increase platelets, while aplastic anemia, myelofibrosis, acute leukemia, radiation injury and other factors will cause thrombocytopenia. In addition, there is another disease that is not fully understood——— primary thrombocytopenic purpura, which is a common bleeding disorder in children and women, and the patient has a very low platelet spine content, and is prone to bruising and purple spots on the body, ** mucosa is easy to bleed, and nosebleeds are easy.

If there is unexplained bruising or bleeding on the body, you must seek medical attention in time and have a platelet count test to clarify the symptoms and treat the symptoms.
