AI Article Synopsis

  • The study investigated the relationships between serum lipid levels and hemostatic factors in men and women, emphasizing the limited existing research on this topic.
  • In the KORA-Fit study involving 805 participants, multivariable linear regression models were used to explore these associations.
  • Findings revealed that men and women exhibit different patterns of association between lipid levels and coagulation factors, suggesting the need for further research to understand their implications for cardiovascular risk.

Article Abstract

Background: Studies on the associations between lipid parameters and different hemostatic factors in men and women from the general population are scarce. It was therefore examined whether there are possible relationships between routinely measured serum lipids (total cholesterol, HDL-cholesterol, non-HDL-cholesterol, LDL-cholesterol, and triglycerides) and different hemostatic factors (activated partial thromboplastin time (aPTT), fibrinogen, factor VIII, antithrombin III (AT III), protein C, protein S, and D-dimer).

Methods: The analysis was based on data from the Cooperative Health Research in the Region of Augsburg (KORA)-Fit study, which included 805 participants (378 men, 427 women) with a mean age of 63.1 years. Sex-specific associations between serum lipids and coagulation factors were investigated using multivariable linear regression models.

Results: In men, total cholesterol was inversely related to aPTT but positively associated with protein C activity. HDL cholesterol was inversely related to aPTT and fibrinogen. LDL cholesterol, non-HDL cholesterol, and triglycerides showed a positive association with protein C and protein S activity. In women, LDL-cholesterol, total cholesterol, and non-HDL-cholesterol were positively related to AT III concentrations and protein C and S activity. Additionally, non-HDL-cholesterol was positively associated with factor VIII activity. HDL cholesterol was inversely related to fibrinogen. Triglycerides showed a positive relationship with protein C activity.

Conclusions: There seem to be sex differences regarding various associations between blood lipid levels and hemostatic factors. Further studies are needed to address the possible impact of these associations on cardiovascular risk and the underlying mechanisms.

Objective: Hemostatic abnormalities, including disseminated intravascular coagulation (DIC), are often cited as a common finding in patients following Loxosceles spider envenomation (ie, loxoscelism). The prevalence and severity of coagulopathy, however, particularly following L reclusa (ie, brown recluse) envenomation, is not well described. This study aimed to characterize coagulation laboratory parameters and coagulopathy in patients following L reclusa envenomation.

An 83-year-old male presented to our Digestive System Department with a 5-day history of severe gastrointestinal (GI) bleeding and a 14-year history of idiopathic thrombocytopenic purpura (ITP) with low platelet levels. Colonoscopy revealed extensive telangiectasias throughout the colon, particularly in the transverse and ascending segments. Standard treatment with proton-pump inhibitors and somatostatin proved ineffective.

Blood clots (BCs) play a crucial biomechanical role in promoting osteogenesis and regulating mesenchymal stem cell (MSC) function and fate. This study shows that BC formation enhances MSC osteogenesis by activating Itgb1/Fak-mediated focal adhesion and subsequent Runx2-mediated bone regeneration. Notably, BC viscoelasticity regulates this effect by modulating Runx2 nuclear translocation.

Interaction and cleavage of cell and plasma proteins by the platelet-aggregating serine protease PA-BJ of Bothrops jararaca venom.

Laboratory of Applied Toxinology, Center of Toxins, Immune-Response and Cell Signaling (CeTICS), Butantan Institute, São Paulo, Brazil. Electronic address:

PA-BJ is a serine protease present in Bothrops jararaca venom that triggers platelet aggregation and granule secretion by activating the protease-activated receptors PAR-1 and PAR-4, without clotting fibrinogen. These receptors also have a relevant role in endothelial cells, however, the interaction of PA-BJ with other membrane-bound or soluble targets is not known. Here we explored the activity of PA-BJ on endothelial cell receptor, cytoskeleton, and coagulation proteins in vitro, and show the degradation of fibrinogen and protein C, and the limited proteolysis of actin, EPCR, PAR-1, and thrombomodulin.

Objectives: Chronic Kidney Disease (CKD) has been associated with a prothrombotic state. CKD affects hemostasis through altered platelet function and coagulation factors. Traditional tests provide limited insight into these changes.
