Deficiency of plasma protein S, protein C, or antithrombin III and arterial thrombosis
1Department of Medicine, State University of New York, Stony Brook 11794.
Insights
Deficiencies in protein C, protein S, or antithrombin III, crucial anticoagulants, were linked to extensive arterial thrombosis in three patients. These findings suggest these protein deficiencies are potential risk factors for arterial clot formation.
Area of Science:
- Biochemistry
- Hematology
- Vascular Biology
Background:
- Protein C and protein S are vitamin K-dependent coagulation factors.
- Antithrombin III is a plasma protein that inhibits coagulation factors.
- Deficiencies in these proteins are typically associated with venous thrombosis.
Observation:
- Three patients presented with deficiencies in protein C, protein S, or antithrombin III.
- All three patients experienced extensive arterial thrombosis.
- This contrasts with the usual association of these deficiencies with venous issues.
Findings:
- Protein S deficiency was observed in one patient.
- Protein C deficiency was observed in another patient.
- Antithrombin III deficiency was observed in a third patient.
Implications:
- Deficiencies in protein C, protein S, and antithrombin III may be significant risk factors for arterial thrombosis.
- This highlights the potential role of these anticoagulant proteins in preventing arterial clot formation.
- Further research is warranted to elucidate the mechanisms linking these deficiencies to arterial thrombosis.
Abstract:
Protein C and protein S are vitamin K-dependent coagulation factors that together act as an anticoagulant, and antithrombin III is a plasma protein that inhibits several activated factors in the coagulation cascade. Although deficiencies of any of these three proteins have been associated with deficiencies of these factors. We report one patient with a protein S deficiency, another with a protein C deficiency, and a third with an antithrombin III deficiency, each of whom who had extensive arterial thrombosis. We suggest that deficiencies of these proteins may constitute risk factors for arterial thrombosis.
