广州市某医院就诊人群粪便寄生虫检测分析

Detection of fecal parasites in patients in a hospital in Guangzhou

目的分析广州市某医院粪便常规检测中寄生虫检出情况,为粪便寄生虫检验及肠道寄生虫疾病防治提供参考依据。方法收集2023年1-12月广东省第二中医院就诊患者粪便标本,采用沃文特FA280全自动粪便分析仪进行常规检测,并对检出寄生虫虫种及感染率等数据进行分析。结果累计收集24547例患者粪便样本进行粪便寄生虫检查,其中男11754例,女12793例,平均年龄(63.85±17.48)岁,共检出5种寄生虫合计1043例,总感染率为4.25%,包括华支睾吸虫(1018例,4.15%)、钩虫(12例,0.05%)、人芽囊原虫(8例,0.03%)、粪类圆线虫(2例,0.01%)、蛲虫(3例,0.01%),其中1例混合感染华支睾吸虫及钩虫。华支睾吸虫感染率最高,男性(6.45%)高于女性(2.03%),差异有统计学意义(χ^(2)=299.47,P<0.01),感染率随年龄增长而增长,40~<50岁阶段感染率较高,但自70岁后开始逐渐下降;钩虫感染率男性(0.09%)高于女性(0.02%);粪类圆线虫感染者均为老年男性;人芽囊原虫感染者均为成人;蛲虫感染者均为<6岁的幼儿;未检出蛔虫、鞭虫以及其他肠道寄生虫。华支睾吸虫感染者主要来自内科科室,以肿瘤(6.96%)、肾病(6.22%)、内分泌(5.73%)及消化科(5.54%)为多。结论广州地区人体寄生虫病感染率不容小觑,华支睾吸虫仍为广州地区主要人体感染肠道寄生虫,需加强防控工作。

Objective To analyze the detection of parasites in routine fecal examination in a hospital in Guangzhou,and provide reference for the detection of fecal parasites and the prevention and treatment of intestinal parasitic diseases.Method The fecal samples of patients in Guangdong Provincial Second Hospital of Traditional Chinese Medicine from January to December 2023 were collected,and the routine detection was performed by the Wowente FA280 automatic fecal analyzer,and the detection of parasites and infection rate were analyzed.Results A total of 24547 stool samples were collected for helminth examination,including 11754 males and 12793 females,with an average age of(63.85±17.48)years old.A total of 1043 cases of 5 kinds of parasites were detected,and the total infection rate were 4.25%,including 4.15%for Clonorchis sinensis,0.05%for hookworm,0.03%for Blastocystis hominis,0.01%for Strongyloides stercoralis,and 0.01%for pinworm.One case was found to be co⁃infected with Clonorchis sinensis and hookworm.The infection rate of Clonorchis sinensis was the highest,with a male⁃to⁃female ratio of 6.45%to 2.03%,which was statistically significant(χ^(2)=299.47,P<0.01).The infection rate increased with age,with the higher rate in the 40~<50⁃year⁃old age group,but began to decline after age 70.The male⁃to⁃female ratio of hookworm infection was higher(0.09%vs.0.02%),and all Strongyloides stercoralis infections were found in elderly male patients.Strongyloides stercoralis infections were found only in adults,and pinworm infections were found only in children<6 years of age;no roundworms,whipworms or other intestinal parasites detected.Clonorchis sinensis infections were mainly from patients in the internal medicine departments,with oncology 6.96%,nephrology 6.22%,endocrinology 5.73%,and gastroenterology 5.54%as the leading departments.Conclusion The prevalence of helminth infections in Guangzhou cannot be ignored,and Clonorchis sinensis remains the main human intestinal parasite in Guangzhou,requiring strengthened control measures.
