Outline of Final Research Achievements

In 466 patients with acute type A aortic dissection (ATAAD) treated surgically within 48 hours of symptom onset, patients’ white blood cell (WBC) count differed significantly in relation to the extent of dissection. With 11,000/μL used as the cut-off value for WBC count elevation, multivariable analysis showed current smoking (p<0.001, OR:2.79), dissection extending to the iliac artery (p=0.006, OR:1.79), and age (p=0.007, OR:0.98) to be factors related to the elevated WBC count.
Total RNA was isolated from the intima-media layer of dissected ascending aorta obtained intraoperatively from ATAAD patients with unruptured aneurysm (n=5) and with ruptured aneurysm (n=3). Gene expression profiling was performed with mRNA microarrays. Microarray analysis revealed that 816 genes (2.0% of 42,545 probes) were differentially expressed in the rupture group. The top 14 related pathways included inflammatory response, leukocyte migration, leukocyte chemotaxis, and innate immune response.

Academic Significance and Societal Importance of the Research Achievements

急性大動脈解離は、成人突然死の代表的疾患であり、急性期に出現する大動脈破裂が予後に大きな影響を及ぼす。ヒト症例を対象とした急性の炎症反応や大動脈破裂に関する研究は少なく、炎症反応の指標である末梢血白血球数増多に関しても背景因子の報告がなかった。
今回実施した研究により、解剖学的には大動脈解離の遠位側への進展が末梢血白血球増多と関連することが明らかになった。また、急性A型大動脈解離症例の大動脈組織を使用した網羅的遺伝子発現解析研究では、急性期炎症反応経路の発現増強が確認された。今後本研究を更に推進し、大動脈破裂の早期診断や早期治療実施につながるバイオマーカー開発を目指す。
