히로시 오구라 교수의 연구실은 중증 손상과 패혈증에서 발생하는 응고 이상과 면역 반응의 상호작용을 중심으로 한 임상적·기전적 연구를 수행하고 있습니다. 특히 혈소판 활성화, 백혈구-혈소판 상호작용, SIRS(전신염증반응증후군)와 연관된 응고 이상이 장기 기능 이상을 유도하는 메커니즘을 규명하고자 합니다. 이를 바탕으로 패혈증 및 충격 환자의 예후 개선을 위한 임상지침(J-SSCG 2020) 개발에도 기여하고 있습니다.

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2020 (J-SSCG 2020), a Japanese-specific set of clinical practice guidelines for sepsis and septic shock created as revised from J-SSCG 2016 jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in September 2020 and published in February 2021. An English-language version of these guidelines was created based on the contents of the original J
Activated platelets enhance microparticle formation and platelet-leukocyte interaction in severe trauma and sepsis. Enhanced platelet-leukocyte interaction is dependent on P-selectin expression and may be involved in the systemic inflammatory response after severe inflammatory insult.
Severe trauma stimulated acute-phase priming in PMNL and inhibited apoptosis. Infections after trauma induced second-hit priming in PMNL, but the unchanged serum levels of thrombomodulin suggest that priming per se may not cause systemic vascular endothelial damage.

In critically ill patients with thrombocytopenia, coagulopathy and organ dysfunction progress with significant mutual correlation, depending on the increase in SIRS scores. The SIRS-associated coagulopathy may play a critical role in inducing organ dysfunction after severe insult.
We report the reversible MR findings in a 7-year-old girl with hemolytic uremic syndrome and mild encephalopathy. The splenium of the corpus callosum showed isointense to low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, representing local edema. These findings returned to near normal on MR images obtained 1 week later. The patient recovered without CNS impairment.
Activated vascular endothelial cells with increased procoagulant activity enhance production of microparticles with increased binding to leukocytes in patients with severe SIRS. Endothelial microparticles may be involved in the pathogenesis of endothelial injury after severe insult.
