Researchers have yet to determine the exact incidence of this condition. However, studies estimate there\u2019s about 1 new case of PTP per 24,000 to 100,000 transfusions [<a href=\"https:\/\/amjcaserep.com\/abstract\/full\/idArt\/942949\">1<\/a>].&nbsp;<\/p>\r\n\r\n\r\n\r\n<p>The characteristic feature of PTP is a sudden, drastic drop in platelet count, which usually occurs within 14 days of blood or platelet transfusion. A low platelet count after a transfusion is typically self-limiting, often resolving within 2 weeks.&nbsp;<\/p>\r\n\r\n\r\n\r\n<p>However, in severe cases, death may occur due to bleeding inside the skull or brain. Approximately 1 in 3 patients has major bleeding.&nbsp;<\/p>\r\n\r\n\r\n<div class=\"wp-block-image\">\r\n<figure class=\"alignright size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"420\" height=\"271\" src=\"https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2025\/07\/blood-transfusion.jpg\" alt=\"Patient receiving a blood transfusion in a hospital\" class=\"wp-image-27707\" srcset=\"https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2025\/07\/blood-transfusion.jpg 420w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2025\/07\/blood-transfusion-300x194.jpg 300w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2025\/07\/blood-transfusion-18x12.jpg 18w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2025\/07\/blood-transfusion-86x55.jpg 86w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2025\/07\/blood-transfusion-167x108.jpg 167w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2025\/07\/blood-transfusion-280x181.jpg 280w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2025\/07\/blood-transfusion-370x239.jpg 370w\" sizes=\"auto, (max-width: 420px) 100vw, 420px\" \/><\/figure>\r\n<\/div>\r\n\r\n\r\n<p>Symptoms can include:<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Post-transfusion fever<\/li>\r\n\r\n\r\n\r\n<li>Unusual purpuric rashes (red or purple spots beneath the skin)<\/li>\r\n\r\n\r\n\r\n<li>Bruising\u00a0<\/li>\r\n\r\n\r\n\r\n<li>Nosebleeds<\/li>\r\n\r\n\r\n\r\n<li>Gum bleeding\u00a0<\/li>\r\n\r\n\r\n\r\n<li>Bleeding in the digestive and urinary tracts<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\" id=\"h-what-causes-post-transfusion-purpura\"><span class=\"ez-toc-section\" id=\"What_Causes_Post-Transfusion_Purpura\"><\/span>What Causes Post-Transfusion Purpura?<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n\r\n\r\n\r\n<p>PTP can occur when the antibodies (proteins) directed against transfused platelets attack and destroy the receiver\u2019s platelets.

Nevertheless, IVIG is often considered the treatment of choice for PTP.&nbsp;<\/p>\r\n\r\n\r\n\r\n<p>IVIG is highly effective, with a reported response rate of 90% and a favorable response within 48 hours after starting IVIG therapy.&nbsp;<\/p>\r\n\r\n\r\n\r\n<p>Many studies and case reports have found that high-dose IVIG is effective in:<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Rapidly increasing platelet counts<\/li>\r\n\r\n\r\n\r\n<li>Stopping bleeding\u00a0\u00a0<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>For example, according to a 2025 case report published in the Canadian Medical Association Journal, researchers successfully treated a 36-year-old woman suspected of having PTP with IVIG and a steroid.&nbsp;<\/p>\r\n\r\n\r\n\r\n<p>The patient received 1 g\/kg\/day of IVIG for 4 days, from days 10 to 13. She also received 40 mg\/day of dexamethasone from days 11 to 14.

How is post-transfusion purpura treated?<\/h4>\r\n\r\n\r\n\r\n<p>High-dose IVIG is the first-line treatment for post-transfusion purpura. If symptoms don\u2019t improve, your provider may recommend plasma exchange or corticosteroids. Platelet transfusions are rarely used and should be reserved for patients with severe bleeding.&nbsp;<\/p>\r\n\r\n\r\n\r\n<h4 class=\"wp-block-heading\" id=\"h-2-how-does-ivig-help-with-thrombocytopenia\">2. How does IVIG help with thrombocytopenia?<\/h4>\r\n\r\n\r\n\r\n<p>The exact mechanism isn\u2019t fully understood. It is believed that IVIG helps restore platelet count by preventing the body from removing antibody-coated platelets and neutralizing antibodies.&nbsp;<\/p>\r\n\r\n\r\n\r\n<h4 class=\"wp-block-heading\" id=\"h-3-how-quickly-does-ivig-increase-platelets\">3. How quickly does IVIG increase platelets?<\/h4>\r\n\r\n\r\n\r\n<p>IVIG increases platelet count typically within 48 to 72 hours after starting treatment. The time it takes to increase platelet count depends on the patient\u2019s platelet levels at the time of starting IVIG, the severity of the condition, and the doses of IVIG administered.<\/p>\r\n","protected":false},"excerpt":{"rendered":"<p>IVIG (globulin mi\u1ec5n d\u1ecbch ti\u00eam t\u0129nh m\u1ea1ch) l\u00e0 ph\u01b0\u01a1ng ph\u00e1p \u0111i\u1ec1u tr\u1ecb ch\u00ednh cho b\u1ec7nh xu\u1ea5t huy\u1ebft sau truy\u1ec1n m\u00e1u.
