SummaryObjective: To investigate if the factor V Leiden mutation (F-V-LM) and/or the prothrombin gene G 20210 A variant (P-G20210A-V) are risk factors for acute stroke in Austrian children. Patients: 33 children with acute ischemic stroke documented by computer tomography and/or magnetic resonance imaging of the brain were enrolled in an open multicenter survey. Results: 6/33 children had F-V-LM (5 heterozygous, 1 homozygous). This represents 18% (95% CI: 6.7-39.9%) of our pediatric stroke population and thus exceeds the expected prevalence in the Austrian population of 4,6% (Fischer’s exact test, p = 0.01). F-V-LM was not found in 11 children with neonatal stroke but in 6/22 children with stroke after the neonatal period. 5/6 children with F-V-LM had an underlying disorder that is a risk factor for stroke in children. The P-G20210A-V was detected in 1/26 (3.85%; 95% CI: 0.1-21.4%) patients. Comparison of the prevalence of P-G20210A-V in our study with that in the general population of Austria of 1% revealed no statistical significance (Fischer’s exact test, p = 0.38). Conclusion: Our data suggest that the F-V-LM is a risk factor for acute stroke in Austrian children beyond the neonatal period. The P-G20210A-V apparently does not represent a risk factor for stroke in Austrian children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
