摘要
难辨梭状芽孢杆菌是一种革兰阳性肠道病原体。难辨梭状芽孢杆菌相关性腹泻(CDAD)及其引起的假膜性肠炎为消化道多发病。难辨梭状芽孢杆菌可产生毒素A和毒素B,侵入肠黏膜后引起细胞病变,导致一系列感染相关临床表现。免疫学机制在难辨梭状芽孢杆菌感染相关疾病的发病中起重要作用。本文就CDAD的发病机制、临床表现及其检测和治疗作一综述。
Clostridium difficile is a gram-positive enteric pathogen. Clostridium difficile-associated diarrhea (CDAD) and pseudomembranous enteritis, a serious complication of CDAD, are frequently seen in GI clinics. Damage of intestinal mucosa cells induced by toxin A and toxin B of Clostridium difficile is responsible for the clinical manifestations of the disease. Immunologic mechanism plays an important role in the development of Clostridium difficile-associated diseases. The pathogenesis, clinical manifestations, diagnosis and treatment of CDAD were reviewed in this article.
