Tigecycline is a broad-spectrum active intravenous antibiotic that is active against methicillin-resistant staphylococcus aureus. In Phase 3 and 4 clinical trials, increased all-cause mortality was observed in patients treated with tigecycline compared to patients in the control group. The reason for the increase is unclear. In this study, we found that tigecycline cause abnormal coagulation in tumor patients, especially in patients with hematological malignancies. The main manifestations were decreased fibrinogen and prolonged activated prothrombin time (APTT), thrombin time (TT), and D-dimer. In addition, through functional studies, we found that tigecycline inhibit platelet adhesion and aggregation, and the coagulation function of patients gradually recover after discontinuation. Gene sequencing results suggested that tigecycline significantly regulate the expression of genes related to platelet function pathways and increase the incidence of single nucleotide polymorphisms and the number of alternative splices in the Chinese hamster ovary (CHO) cells treated with tigecycline. An abnormal function and low numbers of platelets are common in patients with hematological malignancies. Our study can explain the mechanism of abnormal coagulation caused by tigecycline. Additionally, doctors who apply tigecycline to cure infections in tumor patients should be warned.

Background: The role of a prothrombotic state in atrial fibrillation (AF) progression to permanent arrythmia (PerAF) is unclear. Formation of denser and poorly lysable fibrin clots has been observed in AF patients also with sinus rhythm in association with higher stroke risk. We investigated whether altered fibrin clot properties and other prothrombotic state markers may contribute to AF transition to PerAF.

Acquired factor XIII (FXIII) deficiency is a rare disorder that could be associated with autoimmune and malignant disorders with a high risk of bleeding. In acute leukemias, acquired FXIII deficiency has been reported and replacement of FXIII helped to control significant bleeding. Here, we report four cases of myeloid neoplasms to have acquired FXIII deficiency with interesting concomitant RUNX1 mutation in the molecular background of two patients.

Background: Haemorrhage is a leading cause of morbidity and mortality in trauma, and prehospital transfusion of blood products is often necessary. Whole blood has been proposed to be the best alternative, but it is unclear whether, and how, storage and transport of the blood in a helicopter affects the blood units. We investigated the coagulation capacity and platelet function in whole blood at different time points during helicopter missions.

Background: Platelet adhesion to collagen, a critical initial step in thrombus formation, remains an underexplored therapeutic target in thrombosis. Current disease treatment strategies primarily focus on platelet activation and aggregation, often overlooking the crucial initial adhesion phase. Reynoutria japonica (Huzhang, HZ), utilized in traditional Chinese medicine to enhance blood circulation and resolve blood stasis, lacks comprehensive insights into its active components and their anti-thrombotic mechanisms.

Background: Deep vein thrombosis (DVT) of the lower limb is a significant clinical challenge with the potential for recurrence, which can lead to increased morbidity and reduced quality of life.
Methods: A retrospective case-control study was conducted involving 367 patients diagnosed with lower limb DVT from June 2020 to June 2023. Patients were categorized into a recurrence group ( = 121) and a non-recurrence group ( = 246) based on DVT occurrence.
