Accuracy of the urine point-of-care circulating cathodic antigen assay for diagnosing Schistosomiasis mansoni infection in Brazil: A multicenter study

Rev Soc Bras Med Trop. 2023 Jan 23:56:e0238-2022. doi: 10.1590/0037-8682-0238-2022. eCollection 2023.

Abstract

Background: The World Health Organization recommends a market-ready, urine-based point-of-care diagnostic test for circulating cathodic antigens (CCA) to determine the prevalence of S. mansoni. This study evaluated the performance of the URINE CCA (SCHISTO) ECO TESTE® (POC-ECO), which is currently available in Brazil.

Methods: Residents from eight sites with different prevalence estimates provided one urine sample for POC-ECO and one stool sample for Kato-Katz (KK) and Helmintex® (HTX) testing as an egg-detecting reference for infection status.

Results: None of the study sites had significantly higher POC-ECO accuracy than KK.

Conclusions: POC-ECO is not currently recommended in Brazilian schistosomiasis elimination programs.
