Introduction Chronic granulomatous disease (CGD) is a primary immune deficiency that characterized with recurrent infections and granuloma formation. A variety of autoimmune disorders and immune-mediated phenomena such as inflammatory bowel disease, discoid lupus erythematous, juvenile idiopathic arthritis, Ig A nephropathy, sarcoidosis, rheumatoid arthritis, idiopathic thrombocytopenia, eosino...

Heparin-induced thrombocytopenia (HIT) is an immune-mediated coagulation side effect of heparin therapy characterized by thrombocytopenia and by a paradoxical prothrombotic state following heparin exposure when thrombotic or thromboembolic events accurse, the condition is classified as Heparin-induced thrombocytopenia with thrombosis (HITT). We report a case of HITT with evidence of small-vesse...

Heparin-induced thrombocytopenia represents a serious side effect of heparin therapy. Immune-mediated platelet activation results in thrombocytopenia, endothelial thrombin release and development of thrombosis, mainly venous. We report the case of a man with a history of coronary artery disease and recent stent implantation. This patient developed severe heparin-induced thrombocytopenia type II...

Systemic lupus erythematosus (SLE) is an inflammatory connective tissue disease mediated by a deregulated immune system and aberrant production of proinflammatory cytokines leading to multiorgan and tissue damage. Thrombocytopenia is a common complication in patients with SLE, with a prevalence that ranges from 7–30%.1-5 The 2 main mechanisms of thrombocytopenia in SLE are increased platelet de...

Heparin is widely used in current practice for a variety of indications. It is well known that it can cause thrombocytopenia, but not that thrombosis may also develop in thrombocytopenic patients and cause significant morbidity and mortality. A 56-year-old woman developed heparin-induced thrombocytopenia with thrombosis that resulted in the amputation of her leg. It is proposed that the reactio...

Chronic immune thrombocytopenic purpura (ITP) is a condition based on an immune-mediated mechanism that determines the premature hyperdestruction of the thrombocytes in peripheral blood, as well as their deficient synthesis at the level of the bone marrow. The chronic immune purpura could be of primary, idiopathic cause, as well as of secondary cause, occurring in the context of other pathologi...

BACKGROUND Subarachnoid hemorrhage (SAH) is a devastating cause of stroke, occurring in relatively young people. It has been suggested that some immune-mediated diseases may be associated with an increased risk of SAH. METHODS We analysed a database of linked statistical records of hospital admissions and death certificates for the whole of England (1999-2011). Rate ratios for SAH were determ...

Immune thrombocytopenia (ITP) comprises a heterogeneous group of disorders characterized by autoimmune-mediated platelet destruction and impairment of thrombopoiesis. ITP may occur in the absence of an evident predisposing etiology (primary ITP) or secondary to a growing list of associated conditions (secondary ITP), and must be differentiated from other causes of thrombocytopenia. This review ...
