Common Causes

The following could cause thrombocytopenic purpura:

medications that prevent platelets from forming or that interfere with normal clotting
drugs that cause the body to launch an immune reaction against platelets
recent blood transfusions
immune disorders such as idiopathic thrombocytopenic purpura
an infection in the bloodstream

Gastrointestinal disease occurs in 65 to 76% of patients. 1,6 Edema and hemorrhage of the bowel wall lead to severe colicky abdominal pain. The ultrasound correlation of uncomplicated pain shows mural thickening and hemorrhage.

Endoscopic findings include ulceration, erythema, edema, hematoma-like protrusions, and petechiae. 8,9 In 14 to 36% of patients, the rash may occur later in the course than the GI manifestations, leading to diagnostic difficulties. Pain consistent with appendicitis can occur before the rash and lead to “unnecessary” appendectomy. Vasculitis and hemorrhage of the abdominal wall musculature can occur, leading to severe pain that can be difficult to diagnose. 7

If your platelet count is dangerously low, your healthcare provider may recommend a platelet or blood transfusion as well.

Thrombotic thrombocytopaenic purpura has a very specific mechanism where an antibody to ADAMTS-13 (A Disintegrin And Metalloprotease with a ThromboSpondin type motif member 13) forms which cleaves a clotting factor (Von Willibrand) leading to uncontrolled clotting. Thrombotic thrombocytopaenic purpura can be linked to a wide range of conditions, including HIV and systemic lupus erythematosus (SLE), and there is a very specific test for diagnosing it that assesses the levels of ADAMTS13 protein. Treatment include immunotherapy and plasmapheresis.

What is purpura fulminans?

The first of these is purpura fulminans, a rare and severe complication of meningococcal septicaemia which is caused by Neisseria meningitidis. Although far more common in tropical countries than in North America, when meningococcal septicaemia does occur, it carries a high mortality-largely because it is not recognized until it’s too late. The bacteria latch on to the endothelial lining of blood vessels and activate the immune system, causing huge inflammation and massive leakage of vascular contents.

What is the cause of hemolytic uraemic syndrome?

Haemolytic uraemic syndrome is generally triggered by E coli infection. E coli shiga toxin binds to ceramide trihexoside on endothelial cells leading to platelet and clotting activation and the condition presents as bleeding and bruising, bloody diarrhoea, vomiting and abdominal pain and renal failure.
