Abstract: Objective To understand the status of current schistosomiasis patients after the interruption of schistosomiasis transmission in Sichuan Province, so as to provide the reference for the development of specific rescue and treatment schemes and the implementation of dynamic management of the patients. Methods The information of registered schistosomiasis patients in disease control and prevention institutions and medical institutions were reviewed in all schistosomiasis?endemic counties (districts) across Sichuan Province in 2018, and the data of all newly discovered schistosomiasis patients were collected and analyzed. Results A total of 1 558 current schistosomiasis cases were diagnosed in 11 endemic cities (prefectures) across Sichuan Province, and all were advanced cases. Megalosplenia and ascites were the predominant types of advanced schistosomiasis cases, and no age? ([χ2] = 16.723, P > 0.05) or gender?specific difference ([χ2] = 2.493, P > 0.05) was seen in the clinical types of current schistosomiasis cases. There were 9.3% of current schistosomiasis patients from poor households. There was a tendency towards a decline in the number of advanced schistosomiasis cases since 2012, and the number of schistosomiasis cases in 2018 reduced by 17.8% as compared to that in 2012. Conclusions Currently, all current schistosomiasis patients are advanced cases in Sichuan Province. In the future, multidisciplinary collaboration should be implemented to search for a feasible financial subsidy pattern and establish an effective care system for advanced schistosomiasis patients.

摘要: 目的 掌握四川省达到血吸虫病传播阻断标准后现症病人情况,为制订专项救治方案、实施病人动态管理提供参考依据。方法 2018年对四川省所有血吸虫病流行地区以县(市、区)为单位,查阅各级疾病预防控制及医疗机构在册血吸虫病患者资料,并走访搜集新发现的现症病人信息进行分析。结果 四川省11个血吸虫病流行市(州)确诊血吸虫病现症病人1 558例,均为晚期血吸虫病病例;患者以巨脾型和腹水型为主,不同年龄组([χ2] = 16.723,P > 0.05)和性别([χ2] = 2.493,P > 0.05)现症病人临床分型差异均无统计学意义。现症病人中贫困户占9.3%,2012年后晚期血吸虫病病例数呈逐年下降趋势,2018年病例数较2012年减少17.8%。结论 四川省血吸虫病现症病人均为晚期血吸虫病病例。今后要开展多学科协作,探索适合晚期血吸虫病患者的资金补助方式,建立完善有效的晚期血吸虫病患者关怀系统。
