Antithrombin III substitution affects survival rate in a murine malaria model

The effect of AT III substitution on survival time was studied inP. vinkei infected mice. One hundred mice were infected, randomly selected and allocated to two groups of 40 animals each on day 13 after infection. One group was placebo treated, the other group received 3 IU AT III daily on days 13 to 19. Comparison of the survival time in the log rank test showed a prolongation of the median survival time (5 versus 9 days,P<0,01). It is concluded that AT III might be beneficial in the treatment of severe malaria cases.
