| Outline of Final Research Achievements |
The aim of the present study was to investigate association between outcome and genetic factor in the pathophysiology of post-cardiac arrest syndrome (PCAS), which is recognized as “sepsis-like syndrome”. Therefore, we performed gene expression profiling analyses for acute phase of the PCAS and compare them with respect to neurologic outcome of the patients. As the results, 90 transcripts were extracted with 14400 oligo DNA microarray by classifying according to neurologic outcome, i.e., cerebral performance category (CPC). Moreover, we identified 4 neutrophil function-related transcripts which altered over time (from ICU day 1 to day 5) according to 90 day outcome. We further analyzed inflammation-related gene polymorphisms using a single nucleotide polymorphism (SNP) chip which we designed, and found several candidate SNPs which were associated with outcome of critically ill patients including PCAS.
