    Abstract:
    To analyze the clinical characteristics of continuous ambulatory peritoneal dialysis (CAPD) associated peritonitis in the tertiary hospitals and to discuss the preventive and therapeutic strategy.
 Methods: The clinical characteristics, pathogens, resistance and outcomes of 126 CAPD associated peritonitis in 104 patients from Jan, 2013 to June, 2016, were retrospectively analyzed.
 Results: Among the patients, the incidence rates of abdominal pain, fever, diarrhea and emesis were 104 (82.54%), 56 (44.44%), 49 (38.89%), and 31 (23.60%), respectively. Among them, 88 patients suffered peritonitis once, other 16 patients suffered multiple peritonitis or recurrent peritonitis for 38 times. Among the 38 times, the numbers for recurrent, repeated or catheter-associated peritonitis were 2, 2, or 3, respectively. Peritoneal fluids from 103 cases were cultured, and 64 cases were positive in bacteria, with a rate of 62.14%. A total of 70 strains of bacteria were separated, including 42 strains of gram-positive bacteria, 21 strains of gram-negative bacteria, and 7 strains of fungus. The most common gram-positive pathogens were Staphylococcus epidermidis, Enterococcus faecalis and Staphylococcus haemolyticus, while Escherichia coli, Klebsiella pneumoniae and Klebsiella pneumoniae were the most common gram-negative bacteria. Candida albicans was the major fungal pathogens. Gram-positive cocci showed resistance to gentamycin, levofloxacin, moxifloxacin, vancomycin and linezolid, with a rate at 20.00%, 36.11%, 5%, 0%, and 0%, respectively. The gram-negative bacilli were resistent to cefoperazone/sulbactam, gentamycin, cephazolin, and ceftazidime, with a rate at 6.25%, 10.53%, 64.29%, and 15.38%, respectively. There were no imipenem, amikacin, piperacillin/tazobactam-resistant strains were found.
 Conclusion: The most common pathogen causing CAPD associated peritonitis is gram-positive bacteria. It is crucial to take the anti-infection therapy for CAPD associated peritonitis early. The positive rates for bacterial culture need to be enhanced through improvement of methods. At the same time, doctors could improve the outcome of CAPD associated peritonitis by adjusting the medication according to the drug sensitivity results. 目的：探讨某三甲医院持续性非卧床腹膜透析(continuous ambulatory peritoneal dialysis，CAPD)相关性腹膜炎临床特点、致病菌分布及耐药性情况，为临床防治CAPD相关性腹膜炎总结经验。方法：回顾性调查该院2013年1月至2016年6月42个月中，104人126例次CAPD相关性腹膜炎患者的临床特点、致病菌分布、耐药性等情况。
结果：在126例次CAPD相关性腹膜炎中，患者出现腹痛104例次(82.54%)，发热56例次(44.44%)，腹泻49例次(38.89%)，呕吐31例次(23.60%)。126例次CAPD相关性腹膜炎中，发生一次腹膜炎的88人次，多次和反复发作的腹膜炎16人38例次，其中复发性腹膜炎2例，腹膜炎重现2例，导管相关性腹膜炎3例。在103例送检的腹水标本中，培养阳性64例次，阳性率达62.14%。共分离出致病菌70株，其中革兰阳性细菌42株，革兰阴性细菌21株，真菌7株。主要的革兰阳性菌包括表皮葡萄球菌、粪肠球菌、溶血葡萄球菌；主要的革兰阴性菌包括大肠埃希菌、肺炎克雷伯菌、铜绿假单胞菌；真菌以白假丝酵母菌为主。革兰阳性菌对庆大霉素、左氧氟沙星、莫西沙星、万古霉素、利奈唑胺的耐药率分别为20.00%，36.11%，5.00%，0%，0%；革兰阴性菌对头孢哌酮/舒巴坦、庆大霉素、头孢唑啉、头孢他啶的耐药率分别为6.25%，10.53%，64.29%，15.38%，对亚胺培南、阿米卡星、哌拉西林/他唑巴坦的耐药率均为0%。结论：革兰阳性菌是CAPD相关性腹膜炎的主要致病菌，临床不仅应尽早开始经验性治疗，而且要考虑如何通过改善培养方法以提高阳性检出率；可以根据药敏结果调整用药，以促进患者CAPD相关性腹膜炎的治愈和腹膜功能的恢复。.
