Thrombosis risk assessment in patients with congenital thrombophilia during COVID - 19 infection.

Background: Coagulation dysfunction represents a serious complication in patients during the COVID-19 infection, while fulminant thrombotic complications emerge as critical issues in individuals with severe COVID-19. In addition to a severe clinical presentation, comorbidities and age significantly contribute to the development of thrombotic complications in this disease. However, there is very little data on association of congenital thrombophilia and thrombotic events in the setting of COVID-19.

Genotype phenotype correlation in a pediatric population with antithrombin deficiency.

Inherited antithrombin (AT) deficiency is a rare autosomal dominant disorder, caused by mutations in the AT gene (SERPINC1). Considering that the genotype phenotype relationship in AT deficiency patients remains unclear, especially in pediatric patients, the aim of our study was to evaluate genotype phenotype correlation in a Serbian pediatric population. A retrospective cohort study included 19 children younger than 18 years, from 15 Serbian families, with newly diagnosed AT deficiency.

Endothelial biomarkers in the light of new sepsis definition.

The aim of our study was to compare usefulness of endothelial biomarkers for severity and outcome prediction in patients with positive Sepsis-3 criteria with traditionally used biomarkers. A total of 150 patients were included in our study. Patients were divided into two groups: patients with sepsis and those with infectious systemic inflammatory response syndrome.

The influence of specific mutations in the AT gene (SERPINC1) on the type of pregnancy related complications.

Background: Inherited antithrombin (AT) deficiency is a rare autosomal dominant disorder, caused by mutations in the SERPINC1 gene. The most common clinical presentation in AT deficient patients includes venous thrombosis and pulmonary embolism, while the association of AT deficiency and its effect on the development of pregnancy complications has been less studied. The aim of our research was to evaluate the effect of AT deficiency types, determined by genotyping, on pregnancy outcomes.

Complement component consumption in sepsis correlates better with hemostatic system parameters than with inflammatory biomarkers.

Introduction: The aim of this study was to investigate the role of C3 and C4 complement components in prediction of sepsis outcome. The secondary aim was to determine relationship between complement components and other inflammatory parameters, and parameters of hemostasis.

Methods: One-hundred-thirty-seven patients with sepsis (Sepsis-3 criteria) were included in the study.

Emergency care of patients receiving non-vitamin K antagonist oral anticoagulants.

Non-vitamin K antagonist oral anticoagulants (NOACs), which inhibit thrombin (dabigatran) and factor Xa (rivaroxaban, apixaban, edoxaban) have been introduced in several clinical indications. Although NOACs have a favourable benefit-risk profile and can be used without routine laboratory monitoring, they are associated-as any anticoagulant-with a risk of bleeding. In addition, treatment may need to be interrupted in patients who need surgery or other procedures.

Clinical and laboratory characteristics of antithrombin deficiencies: A large cohort study from a single diagnostic center.

Introduction: Inherited antithrombin (AT) deficiency is a heterogeneous disease. Due to low prevalence, only a few studies are available concerning genotype-phenotype associations. The aim was to describe the clinical, laboratory and genetic characteristics of AT deficiency in a large cohort including children and to add further laboratory data on the different sensitivity of functional AT assays.

Endogenous thrombin potential as marker of procoagulant response that can be useful in early stage of sepsis.

: Sepsis is associated with complex procoagulant and anticoagulant changes that modify inflammatory response.
