Course of serological tests in treated subjects with chronic Trypanosoma cruzi infection: A systematic review and meta-analysis of individual participant data.

Objective: To determine the course of serological tests in subjects with chronic Trypanosoma cruzi infection treated with anti-trypanosomal drugs.

Methods: A systematic review and meta-analysis was conducted using individual participant data. Survival analysis and the Cox proportional hazards regression model with random effects to adjust for covariates were applied.

Serological reactivity of patients with Echinococcus infections (E. granulosus, E. vogeli, and E. multilocularis) against three antigen B subunits.

In serodiagnosis of cystic echinococcosis (CE) by Echinococcus granulosus infection, antigen B (AgB) has been utilized worldwide. However, it is known that about 40% of sera with alveolar echinococcosis (AE) by Echinococcus multilocularis infection recognize AgB. Furthermore, cross-reaction against AgB was also reported in sera from polycystic echinococcosis (PE) patients with Echinococcus vogeli infection.
