This study investigated the immature platelet fraction (IPF) in assessing treatment effects in immune thrombocytopenia (ITP). IPF was measured on the Sysmex XE2100 autoanalyzer. The mean absolute-IPF (A-IPF) was lower for ITP patients than for healthy controls (3.2 vs 7.8 × 10⁹/L, P < .01), whereas IPF percentage was greater (29.2% vs 3.2%, P < .01). All 5 patients with a platelet response to E...

An effective worldwide vaccination campaign started and is still being carried out in the face of coronavirus disease 2019 (COVID-19) pandemic. While vaccines are great tools to confront pandemic, predominantly adenoviral vector-based can cause a rare severe adverse effect, termed vaccine-induced immune thrombocytopenia thrombosis (VITT), about 1 100,000 vaccinated individuals. VITT diagnosed 5...

We retrospectively investigated the association between platelet autoantibody specificity and response to intravenous immunoglobulin G (IVIG) in 17 patients with immune thrombocytopenia (ITP). Platelet-associated antibodies against glycoprotein (GP) IIb/IIIa, GPIb/IX, and GPIa/IIa were detected in 13, 10, and 8 patients, respectively. A response occurred in 7 of 7 patients without anti-GPIb/IX,...

Platelet refractoriness is caused by HLA antibodies and platelet-specific antibodies. Current methods used to detect antiplatelet antibodies have limitations. Solid phase red cell adherence (SPRCA) lacks sensitivity and requires a second assay using chloroquine-treated intact platelets to specify the response due to anti-HLA. We modified SPRCA by using 2 types of antihuman platelet antibodies w...

Treatment with oral anti-platelet agents constitutes a cornerstone in the therapy of coronary artery disease. Coronary angioplasty and stent implantation improved the therapy of coronary artery disease and especially the treatment of acute myocardial infarction. Implementation of glycoprotein IIb/IIIa inhibition further advanced anti-platelet therapy as a central component in the treatment of a...

The history of platelet function testing intercalates with anti-platelet drug development. Indeed, the original bleeding time test was developed to assess platelet disorders associated with bleeding symptoms. However, this test was found ineffective for testing the response to anti-platelet drugs. The first anti-platelet drug, aspirin, was originally developed as an anti-inflammatory agent late...

We have used immunogold staining to locate thrombospondin (TSP) on thrombin-activated human platelets, and have compared its distribution with that of fibrinogen (or fibrin) on thrombin- and ADP-stimulated platelets. To do this, isolated platelets were incubated with monospecific antibodies to TSP or fibrinogen (fib) and the bound IgG located with a second antibody adsorbed to gold particles. T...

INTRODUCTION The difficulties in the management of the blunt chest wall trauma patient in the Emergency Department due to the development of late complications are well recognised in the literature. Pre-injury anti-platelet therapy has been previously investigated as a risk factor for poor outcomes following traumatic head injury, but not in the blunt chest wall trauma patient cohort. The aim o...
