The differential diagnosis of thrombocytopenia of critically ill patients with sepsis is often complicated and time-consuming. Apart from septic thrombocytopenia we have to consider also the immune thrombocytopenia.
Immune thrombocytopenia may occur as a complication of servere acute infection especially in case of preexisting autoimmune or systemic disease. The leading symptoms are the decrease of platelet count and possible various haemorrhagic symptoms.
In the acute phase the immunosuppressive therapy is indicated (corticosteroids) together with the complex intensive care treatment. We present a case report of suspect immune thrombocytopenia associated with Crohn's disease.
