[Coagulation and fibrinolysis proteins in nephrotic syndromes in children]
Insights
Children with nephrotic syndrome exhibit coagulation and fibrinolysis protein anomalies, potentially increasing thrombosis risk. Low albumin levels correlate with decreased antithrombin III, indicating a significant risk of blood clots.
Area of Science:
- Pediatric Nephrology
- Hemostasis and Thrombosis
- Clinical Biochemistry
Context:
- Nephrotic syndrome in children is associated with complex hemostatic alterations.
- Understanding these changes is crucial for managing thrombotic complications.
Purpose:
- To investigate the specific coagulation and fibrinolysis protein profiles in pediatric nephrotic syndrome.
- To identify potential biomarkers and risk factors for hypercoagulability.
Summary:
- Studied 22 children with nephrotic syndrome, analyzing key coagulation and fibrinolysis proteins.
- Observed increased fibrinogen and clotting factors (II, V, VII+X), and decreased antithrombin III, suggesting hypercoagulability.
- Noted high alpha 2 macroglobulin and low plasminogen, indicating reduced fibrinolytic activity.
- Found that low plasma albumin levels (<15-17 g/l) correlate with low antithrombin III (<23 mg/dl), significantly elevating thrombosis risk.
Impact:
- Highlights the prothrombotic state in pediatric nephrotic syndrome.
- Identifies low antithrombin III and albumin as critical indicators for thrombosis risk assessment.
- Informs clinical management strategies to prevent and treat thromboembolic events in affected children.
Abstract:
The main coagulation and fibrinolysis proteins have been studied in 22 children with nephrotic syndrome. Some anomalies such as the increase of fibrinogen and of Factors II, V, VII + X concentrations and the decrease of antithrombin III concentration could induce an hypercoagulability. Other anomalies such as the high alpha 2 macroglobulin concentration and the frequently low plasminogen concentrations could induce a decrease of the plasma fibrinolytic activity. The consequences of the low alpha 1 antitrypsin levels are probably less important. The fast alpha 2 antiplasmin levels have been found variable in the different patients. Practically, it appears that most children with plasma albumin levels less than 15-17 g/l have antithrombin III levels less than 23 mg/dl (70% of normal), which appears to result in a high risk of thrombosis (11).
