Patients with established cirrhosis are at increased risk of sepsis. Bacterial infections are a frequent cause of morbidity and mortality in patients with advanced liver disease. Mortality for patients admitted to hospital with bacterial infection is approximately 30%, whereas the development of septic shock and multiorgan failure is associated with a mortality of 70-100%. Activation of the hypothalamic-pituitary-adrenal axis is an important feature of a patient's response to severe sepsis and major trauma. An inadequate adrenal response with suboptimal cortisol production has been recognized in patients with septic shock. Patients with septic shock and adrenal insufficiency have reduced response to vasoconstrictor agents, higher rates of refractory shock and high mortality rates. An improvement in survival with administration of hydrocortisone in patients with septic shock and an inadequate adrenal response has been demonstrated. In a more recent study, however, there was no survival benefit in septic shock though reversal of shock was faster with hydrocortisone administration. Recently, adrenal insufficiency has been demonstrated in patients with severe liver disease such as acute liver failure, acute on chronic liver failure, recent liver transplantation and cirrhosis irrespective of the presence of sepsis. Nevertheless survival benefit with administration of hydrocortisone has only been demonstrated in patients with cirrhosis and septic shock. A case report of a patient with cirrhosis and adrenal insufficiency is presented with a review of the literature.
已确诊肝硬化的患者发生脓毒症的风险增加。细菌感染是晚期肝病患者发病率和死亡率升高的常见原因。因细菌感染入院的患者死亡率约为 30%,而发生感染性休克和多器官衰竭与 70-100%的死亡率相关。下丘脑-垂体-肾上腺轴的激活是患者对严重脓毒症和重大创伤反应的重要特征。在脓毒性休克患者中已认识到肾上腺反应不足,皮质醇生成不足。脓毒性休克和肾上腺功能不全的患者对血管收缩剂的反应降低,难治性休克的发生率更高,死亡率也更高。在脓毒性休克患者中给予氢化可的松可提高存活率,这一点已得到证实。然而,在最近的一项研究中,尽管给予氢化可的松可更快地逆转休克,但在脓毒性休克中并未观察到生存获益。最近,在急性肝衰竭、慢性肝衰竭急性发作、近期肝移植和肝硬化等严重肝脏疾病患者中已证实存在肾上腺功能不全,而与脓毒症的存在无关。然而,仅在肝硬化和脓毒性休克患者中给予氢化可的松可提高存活率。本文报告了一例肝硬化合并肾上腺功能不全患者的病例,并对文献进行了复习。
