Abstract:
:Numerous factors affect the response to vitamin K antagonists (VKA) including age, dietary vitamin K, other drugs, pharmacogenetics, and disease states. In antithrombotic guidelines, fever is mentioned as a factor that may increase response to VKA. The purpose of this article is to review the available evidence regarding the effect of fever on response to VKA, and to discuss possible mechanisms of this effect. We performed a search of the English literature from 1943 to June 2014, using the key words fever AND warfarin, acenocoumarol, phenprocoumon, coumarin anticoagulants and VKA; fever AND vitamin K dependent clotting factors II, VII, IX, and X. One animal investigation and 6 studies in humans suggest fever increases response to VKA, but one study did not find a significant effect. The magnitude of this effect is variable. Possible mechanisms for the increased effect of VKA associated with fever are increased catabolism of vitamin K dependent clotting factors, decreased vitamin K intake, and inhibition of VKA metabolism. More rigorous studies are needed to confirm that fever increases response to warfarin and other VKA.
