摘要
ObjectivesIn a previous study performed by our group, Strongyloides stercoralis infection in patients with Chagas disease was associated with higher proportion of Trypanosoma cruzi DNA detection in peripheral blood. The aim of the study was to confirm this association in a larger cohort of patients. MethodsCross-sectional study of all patients with Chagas disease diagnosed from 2005 to 2015 during blood donation at the Catalan Blood Bank. Demographic data and T. cruzi RT-PCR were collected. S. stercoralis infection diagnosis was based on a serological test. ResultsTwo hundred and two blood donors were included. T. cruzi RT-PCR was positive in 72 (35.6%) patients, and S. stercoralis serology was positive in 22 (10.9%) patients. Patients with positive S. stercoralis serology had higher proportion of positive T. cruzi RT-PCR than those with negative serology (54.5% vs. 33.3%, P = 0.050), and the difference increased when taking a serological index cut-off of 2.5, which increases the specificity of the test to detect a confirmed strongyloidiasis (60% vs. 33%, P = 0.017). ConclusionsPatients with Chagas disease with positive S. stercoralis serology had higher proportion of positive T. cruzi RT-PCR in peripheral blood than those with negative serology, which reflects the potential immunomodulatory effects of S. stercoralis in T. cruzi co-infected patients. ObjectifsDans une etude precedente realisee par notre groupe, l'infection par S. stercoralis chez les patients atteints de la maladie de Chagas etait associee a une proportion plus elevee de detection d'ADN de Trypanosoma cruzi dans le sang peripherique. Le but de cette etude etait de confirmer cette association dans une plus grande cohorte de patients. MethodesEtude transversale de tous les patients atteints de la maladie de Chagas, diagnostiques entre 2005 et 2015 au cours du don de sang a la banque de sang catalane. Les donnees demographiques et de la RT-PCR de T. cruzi ont ete recueillies. Le diagnostic de l'infection par S. stercoralis etait base sur un test serologique. Resultats202 donneurs de sang ont ete inclus. La RT-PCR pour T. cruzi etait positive chez 72 (35,6%) patients et la serologie de S. stercoralis etait positive chez 22 (10,9%) patients. Les patients avec une serologie positive pour S. stercoralis avaient une proportion plus elevee de RT-PCR positives pour T. cruzi que ceux avec une serologie negative (54,5% contre 33,3%, p = 0,050) et la difference augmentait lorsqu'un seuil de 2,5 de l'indice serologique etait considere, ce qui augmente la specificite du test pour detecter une strongyloidose confirmee (60% contre 33%, p = 0,017). ConclusionsLes patients atteints de la maladie de Chagas avec une serologie positive pour S. stercoralis avaient une plus forte proportion de RT-PCR positives pour T. cruzi dans le sang peripherique que ceux avec serologie negative, ce qui reflete les effets immunomodulateurs potentiels de S. stercoralis chez les patients coinfectes avec T. cruzi.
