Background: Septic thrombosis of the right atrium is an unusual complication associated with the use of indwelling devices. The optimal management of this condition is unclear. Our experience with a patient with hemodialysis catheter-related septic thrombosis of the right atrium illustrates the difficulties associated with this condition.
Objectives: To determine the effects of surgical thrombectomy compared with nonsurgical treatment with antibiotics (with or without anticoagulation) on mortality rates and complications in patients with device-related septic thrombosis of the right atrium.
Methods: A retrospective analysis of all reported cases of device-related right heart septic thrombosis in which therapy and outcome were reported was conducted using a PubMed search in the English-language literature (1985 to 2006).
Results: Forty cases of device-related right atrial septic thromboses were reported in the literature during the chosen time period. The treatments administered were none (12.5%), antibiotics (12.5%), antibiotics and anticoagulation (20%), and thrombectomy (55%). The mean clot size was significantly larger in patients who underwent thrombectomy. All untreated patients died. Excluding the untreated patients from the analysis, systemic complications were significantly lower in the thrombectomy group than in the groups receiving nonsurgical therapies. Using multivariate modelling with survival as the primary outcome, age, sex, clot size, clot location, microbial organism or type of treatment were not predictive of the outcome.
Conclusion: Device-related right atrial septic thrombosis is associated with significant mortality and is uniformly fatal if untreated. Surgical thrombectomy is associated with less frequent systemic complications. A well-designed prospective, randomized trial is needed to determine the optimal treatment of this condition.

Platelets play crucial roles in multiple pathophysiological processes after energy-dependent activation. It is puzzling how such a small cellular debris has abundant energy supply. In this study, it is shown that insulin-regulated aminopeptidase (IRAP), a type II transmembrane protein, is a key regulator for platelet activation by promoting energy regeneration during septic thrombosis.

Sepsis is a life-threatening disease characterized by excessive systemic inflammation and coagulopathy. Platelets and neutrophils form a "dangerous alliance" through crosstalk, promoting the inflammatory cytokine storm and coagulation disorders during sepsis. Platelet-neutrophil crosstalk leads to the formation of platelet-neutrophil complexes (PNCs), which are the central "protagonists" of this "dangerous alliance.

Lemierre's syndrome is a rare and potentially life-threatening complication of head and neck infections, such as bacterial pharyngitis or tonsillitis. It is characterized by the extension of infection into the lateral pharyngeal spaces, leading to subsequent septic thrombophlebitis of the internal jugular vein(s). Although relatively uncommon since the advent of appropriate antibiotic therapy, the incidence of Lemierre's syndrome has increased in the past 15 years, especially among young, healthy adults.

The angiopoietin (Ang)-Tie axis, critical for endothelial cell function and vascular development, is a promising therapeutic target for treating vascular disorders and inflammatory conditions like sepsis. This study aimed to enhance the binding affinity of recombinant Ang1 variants to the Tie2 and explore their therapeutic potential. Structural insights from the Ang1-Tie2 complex enabled the identification of key residues within the Ang1 receptor binding domain (RBD) critical for Tie2 interaction.
