Although rare, passive transfer of platelet antibodies through blood products can result in thrombocytopenia, acute transfusion reactions, and death. We report a case of severe alloimmune thrombocytopenia from a plasma transfusion. A postliver transplant patient with a normal platelet count received fresh frozen plasma before liver biopsy. Postbiopsy, she developed cardiorespiratory distress, petechiae, and severe thrombocytopenia (platelet count 2000/μL). Her platelet count recovered to normal after 1 week. This diagnosis should be considered whenever an unexpected drop in the platelet count occurs after a plasma-rich transfusion. Conservative transfusion practices and more targeted donor screening may prevent similar events.

A New Anti-Interfering Platelet Counting Technology Utilizing Conventional Impedance and White Blood Cell Differential Channel.

Int J Lab Hematol

Department of Laboratory Medicine, The Third Xiangya Hospital, Central South University, Changsha, People's Republic of China.

Introduction: Accurate platelet (PLT) counting is crucial for disease diagnosis and treatment, especially under the condition of thrombocytopenia and platelet transfusion. A few PLT counting approaches have been established including impedance and fluorescent methods. The impedance PLT counting (PLT-I) approach could be interfered by small non-PLT particles in the blood, such as RBC/WBC fragments, microcytes, bacteria, and cryoglobulins.

Introduction: Patients with suspected bacterial infection frequently receive empiric, broad-spectrum antibiotics prior to pathogen identification due to the time required for bacteria to grow in culture. Direct-from-blood diagnostics identifying the presence or absence of bacteria and/or resistance genes from whole blood samples within hours of collection could enable earlier antibiotic optimisation for patients suspected to have bacterial infections. However, few randomised trials have evaluated the effect of using direct-from-blood bacterial testing on antibiotic administration and clinical outcomes.

Autoantibodies against phosphatidylserine and DNA during canine Dirofilaria immitis infection.

Heartworm infection caused by Dirofilaria immitis induces a devastating disease that greatly affects the global canine population. The mechanism leading to heartworm pathology has been attributed to be mostly by mechanical damage of the worm to the dog´s vascular system and immune-mediated, but the latter processes are not completely understood. Autoantibodies targeting host molecules such as lipids and nucleic acids have been described with pathological roles during malaria and COVID-19 and mediating anemia and thrombocytopenia.

Objective This study investigated the regulatory effect of high mobility group protein B1 (HMGB1) in the peripheral blood of patients with primary immune thrombocytopenia (ITP) on myeloid dendritic cells (mDC) and Th17/regulatory T cells (Treg) balance. Methods The study enrolled 30 newly diagnosed ITP patients and 30 healthy controls.Flow cytometry was used to measure the proportion of mDC, Th17, and Treg cells in the peripheral blood of ITP patients and healthy controls.

Article Synopsis
  • TACE is the standard treatment for patients with unresectable, non-metastatic hepatocellular carcinoma, and this study evaluates the effectiveness of adding lenvatinib and pembrolizumab to TACE compared to a placebo.
  • The multicenter, randomised, double-blind phase 3 study (LEAP-012) involved participants from 137 sites across 33 countries who were randomly assigned to receive either TACE with the new drugs or TACE with a placebo.
  • The primary endpoints were progression-free survival and overall survival, and the results reported are from the first interim analysis, which serves as the final analysis for progression-free survival.
