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.

We represent here a 30-year-old woman with cardiac leiomyosarcoma who developed thrombocytopenia and deep vein thrombosis a few days after the start of low molecular weight heparin. Thrombocytopenia improved after replacement of low molecular weight heparin with hirudine. We speculated that cardiac leiomyosarcoma is a predisposing factor for development of heparin induced thrombocytopenia.

Heparin-induced thrombocytopenia can be a serious and difficult-to-diagnose complication of heparin therapy. Serum from patients with heparin-induced thrombocytopenia can cause heparin-dependent platelet aggregation, but the low sensitivity and specificity of this test limit its clinical usefulness. In this report we describe an assay for heparin-induced thrombocytopenia that is both sensitive ...

INTRODUCTION The pathogenesis of thrombocytopenia in patients with sepsis is not fully understood. The aims of this study were to investigate changes in thrombopoietic activity over time by using absolute immature platelet counts (AIPC) and to examine the impact of platelet production on thrombocytopenia and mortality in patients with sepsis. METHODS This retrospective observational study inc...

Thrombocytopenia in patients with chronic hepatitis C virus (HCV) infection is a major problem. The pathophysiology is multifactorial, with auto-immunogenicity, direct bone marrow suppression, hypersplenism, decreased production of thrombopoietin and therapeutic adverse effect all contributing to thrombocytopenia in different measures. The greatest challenge in the care of chronic HCV patients ...

BACKGROUND AND OBJECTIVE Flow cytometry (FC) to identify platelet-associated (PA) immunoglobulin (Ig) is a potentially useful diagnostic test for idiopathic thrombocytopenic purpura (ITP). However, the restricted application of PAIg measurement to thrombocytopenic populations primarily comprised of ITP patients will artificially enhance the test's diagnostic specificity. For this reason, we per...

BACKGROUND Antimicrobial-induced thrombocytopenia is frequently described in the literature among critically ill patients. Several antimicrobials have been implicated, although experimental evidence to demonstrate causality is limited. We report, using a randomized trial, the potential of antimicrobials to induce thrombocytopenia. METHODS Randomized trial allocated patients to antimicrobial t...

OBJECTIVE To evaluate potential risk factors, presenting symptoms, management, and outcomes of intracranial haemorrhage in Chinese children with immune thrombocytopenia managed in a regional hospital. DESIGN Retrospective case series. SETTING A regional hospital in Hong Kong. PATIENTS All paediatric patients with immune thrombocytopenia complicated by intracranial haemorrhage in the perio...
