Delayed recovery of platelet count post allogeneic hematopoietic stem cell transplantation (allo-HSCT) has been associated with worse transplant outcomes. Thrombopoietic agents have been successfully used in immune mediated thrombocytopenia or thrombocytopenia from bone marrow failure syndromes; however, the experience regarding their use after allo-HSCT is limited. Here we report on the safety...

Heparin-induced thrombocytopenia (HIT) is the most important and most frequent drug-induced, immune-mediated type of thrombocytopenia. It is associated with significant morbidity and mortality if unrecognized. In this review, we briefly discuss the main features of heparin-induced thrombocytopenia, particularly analyzing the most recent advances in the pathophysiology, diagnosis and treatment o...

Severe thrombocytopenia during or after the course of Zika virus infection has been rarely reported. We report 7 cases of severe thrombocytopenia and hemorrhagic signs and symptoms in Guadeloupe after infection with this virus. Clinical course and laboratory findings strongly suggest a causal link between Zika virus infection and immune-mediated thrombocytopenia.

BACKGROUND AND OBJECTIVES Despite an extensive search for a definitive diagnostic assay for platelet autoantibodies, the laboratory diagnosis of immune thrombocytopenia (ITP) still remains a clinical challenge. Data in the literature have so far demonstrated that measurement of platelet-associated IgG (PAIgG) is sensitive, especially when flow cytometry is employed, but lacks adequate specifici...

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: Atypical hemolytic uremic syndrome (aHUS) is a life-threatening and scarce disorder characterized by acute renal failure and disease, non-immune microangiopathic hemolytic anemia and thrombocytopenia, leading to end-stage renal failure or death, and consequently maybe accompanying by extra renal manifestations. Case report: We reported aHUS accompanied by autoimmune hemolytic anemi...

INTRODUCTION Immune thrombocytopenic purpura is thought to be characterized by an immune response against the host's own platelets. If the thrombocytopenia is severe, patients are initially treated with high-dose steroids. Other more toxic second line treatments are considered if steroids fail. Here, we report the case of two patients in whom conventional treatment was unsuccessful but who resp...

BACKGROUND Thrombocytopenia can occur in different circumstances during childhood and although immune thrombocytopenia is its most frequent cause, it is important to consider other conditions, especially when there is a persistent or recurrent low platelet count. We report two cases of intermittent thrombocytopenia, previously misdiagnosed as immune thrombocytopenia. CASES PRESENTATION Both c...

Human immunodeficiency virus (HIV) associated thrombocytopenia was commonly encountered in the era prior to the advent of antiretroviral therapy (ART). With the widespread use of ART, its incidence has significantly declined. Immune reconstitution inflammatory syndrome (IRIS) is an immune dysregulation phenomenon that reveals itself clinically as paradoxical deterioration after the commencement...
