摘要

十二指肠贾第虫是全世界肠胃炎的重要来源。已在发展中国家和工业化国家描述了地方性病例。我们通过系统综述和文献荟萃分析来分析散发性贾第虫病的危险因素。从72项研究中,与感染者接触,缺乏个人卫生,以及参加儿童日托中心被确定为儿童和成人的危险因素。粪口传播与接触人类污水/废水、未经处理的饮用水和娱乐用水密切相关。在工业化国家,出国旅行是一个危险因素。进食或准备食物前不洗手、食用未经清洗的蔬菜或复合食物是重要的危险因素。在发展中国家,母乳喂养是一个保护因素。有趣的是,在这项荟萃分析中,与宠物接触被发现是儿童的重要风险因素。这可以在未来的研究中通过比较从人类和宠物分离的贾第鞭毛虫组合来探索。在未来,更精确地研究水、蔬菜的类型,以及任何可能的制备/处理方法,将是一件有趣的事情。应进一步研究贾第鞭毛虫组合和类型的特定危险因素的环境和流行病学调查。最后,宿主因素与贾第虫病严重程度和后遗症的关系值得进一步研究。

Risk factors for sporadic giardiasis: a systematic review and meta-analysis

Giardia duodenalis is an important source of gastroenteritis worldwide. Endemic cases have been described in developing and industrialized countries. We analyzed risk factors for sporadic giardiasis by a systematic review and a meta-analysis of the literature. From 72 studies, contact with an infected person, lack of personal hygiene, and attending a child daycare center were identified as risk factors in children and adults.

Feco-oral transmission was significantly associated with exposure to human sewage/waste water, untreated drinking water and recreational waters. Travel abroad was a risk factor in industrialized countries. No handwashing before eating or preparing food, eating unwashed vegetables, or composite food were significant risk factors. Breastfeeding was a protective factor in developing countries. Interestingly, contact with pets was found as a significant risk factor in children in this meta-analysis. This could be explored in future studies with the comparison of the Giardia assemblage isolated from humans and pets. In the future, it would be interesting to investigate more precisely the type of water, vegetable, and whenever possible the method of preparation/treatment. Environmental and epidemiological investigations of specific risk factors by assemblages and types of Giardia spp. should be further studied. Finally, host factors in relationship with the severity and sequelae of giardiasis deserve future research.

期刊介绍: The journal Microbial Risk Analysis accepts articles dealing with the study of risk analysis applied to microbial hazards. Manuscripts should at least cover any of the components of risk assessment (risk characterization, exposure assessment, etc.), risk management and/or risk communication in any microbiology field (clinical, environmental, food, veterinary, etc.). This journal also accepts article dealing with predictive microbiology, quantitative microbial ecology, mathematical modeling, risk studies applied to microbial ecology, quantitative microbiology for epidemiological studies, statistical methods applied to microbiology, and laws and regulatory policies aimed at lessening the risk of microbial hazards. Work focusing on risk studies of viruses, parasites, microbial toxins, antimicrobial resistant organisms, genetically modified organisms (GMOs), and recombinant DNA products are also acceptable.
