RESUMO

The purpose of this essay is to recall the actions taken globally to improve the viral safety of coagulation factor concentrates, mainly in the years 1985-1990, at a time of confusing and often contradictory information on bloodborne viral infections in multitransfused patients with hemophilia (PWHs). I shall first recall the problem of the transmission and control of the hepatitis viruses, and then that of HIV: not only for temporal reasons, but also because understanding the progress of knowledge on hepatitis and the poor success of the early measures taken to tackle this problem in PWHs is essential to understand how the problem of HIV transmission was ultimately dealt with successfully.

RESUMO

The proverb that probably best exemplifies my career in research is attributable to Yogi Berra (http://www.yogiberra.com/), ie, "when you come to a fork in the road ... take it." My career is a consequence of chance interactions with great mentors and talented students and the opportunities provided by a succession of ground-breaking improvements in technology.

RESUMO

Clinical observations have added to the understanding of basic mechanisms of blood coagulation and its alterations in certain hemorrhagic and thrombotic states. Much clinical evidence exists for concluding that the exposure of blood to tissue factor (thromboplastin) on tissue cells represents the key event initiating fibrin clot formation after tissue injury. This then results in the formation of activated factor VII (VIIa)-tissue factor complexes, which must activate both factor X and factor IX for normal hemostasis. I describe the possible clinical consequences of an aberrant function of the natural anticoagulants regulating blood coagulation--antithrombin, protein C, and tissue factor pathway inhibitor. Understanding the physiologic function of tissue factor pathway inhibitor can illuminate why hemophilic patients bleed, but many other questions remain. I briefly review the four causes for acquired disorders of the blood coagulation reactions--vitamin K deficiency, hepatocellular disease, antibodies to clotting factors, and disseminated intravascular coagulation--but limit my comments to the mechanisms that trigger the formation of antibodies to clotting factors and how these antibodies can deplete the blood of clotting factor activities. Finally, heparin is able to potentiate tissue factor pathway inhibitor function, which is a possible reason why the use of heparin but not warfarin can prevent the numerous thrombotic episodes of the Trousseau's syndrome.
