ABSTRACT

La eficacia del tratamiento con factor VII activado recombinante (FVIIar) durante episodios hemorrágicos en pacientes hemofílicos con inhibidores y el conocimiento de su mecanismo de acción, determiná que en los últimos años se ampliara rápidamente su uso en pacientes con hemorragia de diversas causas no controladas con la terapéutica habitual; entre otras, defectos congénitos de la coagulación, trastornos plaquetarios, hepatopatías, cirugía, hemorragia intracraneal, sangramientos digestivos. Aunque un grupo importante de estas comunicaciones se han realizado en forma de casos reportados y serie de casos, se considera que los resultados obtenidos son importantes y que la administración de FVIIar es una alternativa en pacientes con hemorragia grave no controlada. A pesar de su potente acción procoagulante, el riesgo de complicaciones tromboembólicas es bajo y esté relacionado en un grupo importante de pacientes con la presencia de otros factores protrombóticos. En la actualidad se considera que el FVIIar esta indicado en aquellos pacientes con hemorragia masiva que no responden a la terapia con componentes sanguíneos ni a medidas quirúrgicas apropiadas


Effectiveness of the treatment with recombinant activated factor VII (raVII) during the hemorrhagic episodes in hemophilic patients using inhibitions and the knowledge of its action mechanism determined that in pas years its use will be expanded in patients with hemorrhage from non-controlled diverse causes using the usual therapeutics among other, congenital coagulation defects, platelet disorders, liver diseases, surgery, intracranial hemorrhage, digestive bleedings. Although a significant group of these communications have been carried out in reported cases and in cases series, it is considered that the results obtained are important and that the administration of raVII is an alternative in patients presenting with non-controlled severe hemorrhage. Despite its potent pro-coagulant action, thromboembolism complications risk is low and it is related to a significant group of patients with other prothrombotic factors. Nowadays, it is considered that raVII is prescribed in those patients with massive hemorrhage without response either to therapy using blood components or appropriate surgical measures

ABSTRACT

Antecedentes. En el enfermo grave, la hemorragia crítica aguda refractaria al manejo convencional es una complicación frecuente de etiología multifactorial con alta morbilidad y mortalidad. El factor VII recombinante activado (FVIIra) es una nueva alternativa terapéutica en estos casos. Objetivo. Presentar el análisis descriptivo en pacientes no hemofílicos con hemorragia grave tratados con FVIIra. Material y métodos. Diez pacientes no hemofílicos con hemorragia grave, cinco hombres y cinco mujeres, edad entre 18 y 74 años, tratados con FVIIra. Se aplicó una prueba de t para el análisis estadístico. Se consideró una p < 0.001 como significativa. Resultados. Después de la administración del FVIIra se controló la hemorragia y disminuyó el uso de hemoderivados en los diez pacientes tratados (p < 0.001). Los tiempos de coagulación, concentraciones de fibrinógeno, cuenta plaquetaria y parámetros de perfusión tisular mejoraron significativamente después de la aplicación del FVIIra (p < 0.001). Conclusiones. El FVIIra es una alternativa terapéutica útil en enfermos graves que cursan con hemorragia crítica aguda no controlada con el manejo convencional.


BACKGROUND: Severe hemorrhage is a frequent complication with multiple etiologies and high morbi-mortality observed among critically ill patients. Recombinant Factor VIla (rFVlla) constitutes a new therapeutic alternative. OBJECTIVE: Analyze the evolution in a non-hemophiliac patient group with severe hemorrhage treated with rFVlla. MATERIAL AND METHODS: Ten non-hemophiliac patients with severe hemorrhage, five men and five women between 18 and 74 years, were included and treated with rFVIIa. We used a t test for statistic analyses. Significance was set at p < 0.001. RESULTS: Among patients treated with rFVlla, hemorrhage was controlled and the use of blood products was significantly diminished (p < 0.001). Coagulation tests, fibrinogen levels, platelet count and perfusion parameters increased significantly (p < 0.001). CONCLUSIONS: rFVIIa is a therapeutic alternative for the treatment of severe hemorrhage not controlled by conventional management.

ABSTRACT

Recombinant factor VIIa is a novel haemostatic agent and was originally developed to treat haemophilia patients. Successful use of the factor in a 30-year-old male patient with pelvic fracture haemorrhage is being described by the authors.
