Brief Summary:
This is a longitudinal cohort study that will be coordinated with the 2019 schistosomiasis stool survey in Napu The study will use the stool survey results as entry criteria to identify subjects to become the index cases Contact investigation will be conducted to the index cases during home visit Visit 1 The index cases and their contacts meeting the studys eligibility criteria will be recruited For Visit 1 they will be tested for schistosomiasis by on the spot POC-CCA stool samples will be tested for KK at Donggala RD Center Laboratory and urinary tract infection UTI by urine dipsticks stool samples will be tested for schistosomiasis and soil transmitted helminths STH by KK at Donggala RD Center Laboratory and by molecular assay Taqman qPCR at the INA-RESPOND Reference Laboratory while dried blood spots samples will be tested for schistosome antibodies by ELISA at the INA-RESPOND Reference Laboratory The study KK andor POC-CCA will be used to determine their schistosomiasis status Those with positive schistosomiasis status by KK andor POC-CCA will continue follow up to Visit 2 and 3
Detailed Description:
Indonesias plan for elimination of schistosomiasis by 2025 requires a better understanding of the factors associated with infection effective epidemiologic monitoring and optimization of diagnostic and treatment strategies In settings of low prevalence such as Lindu Napu and Bada regions of Central Sulawesi an ultrasensitive technique to diagnose Schistosoma japonicum is needed A diagnostic test that is efficient accurate and easy to use would facilitate collection of reliable epidemiologic information and provide and effective means of assessing the impact of mass drug administration MDA
Primary Objective
To estimate the accuracy of the schistosomiasis point-of-care circulating cathodic antigen POC CCA urine test for monitoring S japonicum infection
Secondary Objective
1 To assess rates of positive testing by POC-CCA rapid urine test serology and molecular methods PCR
2 To evaluate the impact of abnormal urinary findings ie hematuria and markers of urinary tract infections UTI to POC-CCA rapid urine test results
3 To evaluate the efficacy of praziquantel administered by local primary health centers Puskesmas
4 To assess number of schistosome infection using serology and molecular PCR as additional tests to disambiguate discordant results between KK and POC-CCA
5 To assess risk factors related to human schistosome infections
6 To estimate the proportion of soil transmitted helminths infection STH ie roundworms Ascaris lumbricoides whipworms Trichuris trichiura and hookworms Necator americanus and Ancylostoma duodenale in this population
7 To assess the association between color intensity of the POC-CCA rapid urine test band and the schistosome eggs per gram EPG of stool
8 To assess antibody response to schistosome infection The number in the positive KK group will be 40 subjects with the lowest estimated number is 25 subjects Additional positive KK based on the re-testing KK results are expected and should increase the size for the positives For the negatives we calculated that a ratio of 41 negative to positive will be the best fit thus 160 negative KK subjects will be enrolled Additional 20 buffer to the negatives 32 negative KK subjects will also be needed to estimate the specificity of POC-CCA with acceptable 95 CI In total we will enroll between 217 to 232 subjects in this study The study will enroll all positive cases detected by the 2019 stool survey in Napu until the minimum sample size needed is met or until the data collection period has ended
