The protein C pathway.
Review published in Critical care medicine (2000)
Abstract
OBJECTIVE: To examine the role of the protein C anticoagulant pathway in the regulation of microvascular thrombosis. The mechanisms by which inflammation impairs the function of this pathway are also reviewed; conversely, we will survey emerging knowledge of the multiple mechanisms by which the protein C anticoagulant pathway can control the inflammatory response. DATA SOURCES: The information reviewed here was taken from the primary literature, including recent abstracts. STUDY SELECTION: All studies that bear directly on the interrelationship between the protein C anticoagulant pathway and inflammation were included, as was a summary of the initial clinical experience with protein C/activated protein C therapy in sepsis. DATA EXTRACTION AND SYNTHESIS: The results from each of the experimental approaches are summarized. Clinical experience with protein C supplementation in sepsis, although promising, is still in the early stages of study. CONCLUSIONS: The protein C anticoagulant pathway is a major mechanism in controlling microvascular thrombosis. Protein C deficiency that can occur in sepsis facilitates thrombin generation in the microvasculature, probably augmenting inflammatory responses and contributing to endothelial cell dysfunction. Animal studies and preliminary clinical results suggest that protein C/activated protein C supplementation may be useful in reversing microvascular dysfunction.

Por qué esto importa para la hirudoterapia
Esta revisión examina el papel de la vía anticoagulante de la proteína C en la regulación de la trombosis microvascular, analizando tanto cómo la inflamación altera esta vía como la forma en que la proteína C puede modular las respuestas inflamatorias. Los autores resumen datos experimentales y clínicos preliminares que sugieren que la deficiencia de proteína C durante la sepsis facilita la generación de trombina microvascular, contribuyendo a la disfunción endotelial, y que la suplementación con proteína C podría ayudar a revertir esta disfunción. El resumen no contiene ninguna mención de sanguijuelas, hirudina ni hirudoterapia en ningún momento. En consecuencia, este artículo no tiene una conexión directa con el ámbito de la American Society of Hirudotherapy, y cualquier relevancia se limitaría a conocimientos generales sobre la fisiología de la anticoagulación que no son específicos de las terapias basadas en sanguijuelas.
