Insights
Impaired fibrinolysis, indicated by elevated plasminogen activator inhibitor-1 (PAI-1), is linked to multiple organ system failure (MOSF) in children with septic shock and purpura.
Area of Science:
- Pediatric critical care medicine
- Hematology
- Pathophysiology of sepsis
Context:
- Septic shock with purpura presents a critical challenge in pediatric intensive care.
- Understanding the mechanisms of organ dysfunction is crucial for improving outcomes.
Purpose:
- To investigate coagulation and fibrinolysis abnormalities in pediatric septic shock with purpura.
- To determine the association between plasma PAI-1 levels and multiple organ system failure (MOSF).
Summary:
- This observational study analyzed 15 children with septic shock and purpura.
- Patients with MOSF showed lower fibrinogen and antithrombin III levels.
- Elevated plasma PAI-1 concentrations were observed in patients with MOSF and ARDS.
Impact:
- Findings suggest that impaired fibrinolysis may contribute to MOSF development in this patient group.
- Highlights the potential role of PAI-1 as a biomarker for organ dysfunction in pediatric sepsis.
Objective:
To describe abnormalities in coagulation and fibrinolysis in septic shock with purpura and to assess the relationship between plasma plasminogen activator inhibitor-1 (PAI-1) concentrations and multiple organ system failure (MOSF).
Methods:
Observational study in the pediatric intensive care unit of a tertiary care hospital. The presence of early MOSF was assessed at admission in 15 children with septic shock and purpura consecutively admitted to the pediatric intensive care unit. Blood samples were taken to determine coagulation and fibrinolysis parameters.
Results:
At admission, MOSF was diagnosed in 7 patients (46.7 %), acute respiratory distress syndrome (ARDS) in 6 (40 %), consumption coagulopathy in 7 (46.7 %) and acute renal failure in 1 (6.7 %). The overall mortality rate was 40 %. Coagulation parameters were generally affected but statistically significant differences were found only in concentrations of fibrinogen and antithrombin III, which were lower in patients with MOSF than in those without organ dysfunction. Fibrinolysis parameters were increased in all patients but plasma PAI-1 concentrations were significantly elevated only in patients with MOSF and in those with ARDS.
Conclusion:
These data indicate that impaired fibrinolysis could play a major role in the development of MOSF in children with septic shock and purpura.

Introduction to Hemostasis
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized, and...
Coagulation
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...
Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
