摘要:

目的 分析2014-2017年上海市临床医院送检样品寄生虫检测结果,为寄生虫病预防和控制提供基线资料。方法 收集与中国疾病预防控制中心寄生虫病预防控制所签约的上海市相关医疗机构(二甲医院7所、三甲医院28所、涉外医院6所)送检的样品包括全血、血清、粪便、痰液、尿液、体液(胸水、腹水)和组织病理切片、虫体等,以及病例相关信息。采用直接涂片法、改良抗酸染色法、ELISA和分子生物学等方法检测送检样品寄生虫感染情况。结果 2014-2017年共检测送检样品25 549份。其中,病原学检测8 877份,检出寄生虫感染阳性633份,阳性检出率为7.1%,包括了33种寄生虫,其中检出率最高的为人芽囊原虫(331/8 877,3.7%),其次为溶组织内阿米巴(120/8 877,1.4%)。血清学检测16 672份,血清标本阳性1 881份(占10.9%),其中猪囊尾蚴抗体阳性424份(占23.4%),曼氏裂头蚴抗体阳性388份(占21.4%),日本血吸虫抗体阳性289份(占16.0%)、卫氏并殖吸虫抗体阳性267份(占14.7%),刚地弓形虫抗体阳性260份(占14.4%)。原虫感染共371例,主要来源地区为上海(125例);蠕虫感染共87例,主要来源地区为上海(29例)。结论 2014-2017年上海临床医院送检样品中,病原学检测阳性虫种主要是人芽囊原虫和溶组织内阿米巴,血清抗体阳性虫种主要为猪囊尾蚴和曼氏裂头蚴。

Abstract:

Objective To analyze the results of laboratory detection of parasitic infections in clinical samples from hospitals in Shanghai during 2014-2017. Methods Samples included in this study were from hospitals in China which cooperated with National Institute of Parasitic Diseases, Chinese Center for Disease Control and Prevention, consisting of 7 secondary hospitals, 28 tertiary hospitals, and 6 foreign-related hospitals. The samples included whole blood, serum, feces, sputum, urine, body fluids (hydrothorax and ascites), histopathological sections, and worms. Information of the patient’s clinical data was also recorded. Parasitic infection in the samples was examined using direct smear method, modified acid-fast staining method, ELISA, and molecular biological methods. Results A total of 25 549 clinical samples were sent to the institute for examination, including 8 877 samples for pathogen detection, of which 633 (7.1%) were found to be infected with 33 species of parasites. Specifically, 331 samples were with Blastocystis homini (3.7%) and 120 with Entamoeba histolytica (1.4%). In addition, 16 672 samples were examined by the serological method, resulting in positive results for 1 881(10.9%) samples, consisting of 424 samples seropositive for Cysticercus cellulosae (23.4%), 388 for Sparganum mansoni (21.4%), 289 for Schistosoma japonicum (16.0%), 267 for Paragonimus westermani (14.7%), and 260 for Toxoplasma gondii (14.4%). Protozoan infection was detected in 371 samples, most of which were from Shanghai (125 samples), and helminth infection was revealed by ELISA in 87 samples, mainly from Shanghai (29 samples). Conclusion B. hominis and E. histolytica were the major intestinal protozoans in pathogen detection in the samples, and the seropositive cases mainly show possible infection with C. cellulosae and S. mansoni.
