The extent to which the propensity for venous thromboembolism is linked to antipsychotic medication alone or psychosis itself is unclear. The objective of this study was to determine whether markers of thrombogenesis are increased in psychotic patients who have not yet been treated with antipsychotic medication. Methods We investigated the plasma levels of markers indicating activation of coagulation D-dimers and Factor VIII and platelets soluble P-selectin sP-selectin in an antipsychotic-naive group of fourteen men and eleven women with acute psychosis age years body mass index and twenty-five healthy volunteers were matched for age gender and body mass index. Results D-dimers median versus mg l mean versus mg l P and sP-selectin median versus ng ml mean 124 versus 32 P plasma levels were significantly increased in the group of patients with acute psychosis as compared with healthy volunteers. We found a trend median 148 versus 110 mean 160 versus 123 P of increased plasma levels of factor VIII in psychotic patients as compared with healthy volunteers. Conclusions The results suggest that at least a part of venous thromboembolic events in patients with acute psychosis may be induced by pathogenic mechanisms related to psychosis rather than by antipsychotic treatment. Finding an exact cause for venous thromboembolism in psychotic patients is necessary for its effective treatment and .
