Toxoplasma gondii transmitted from blood donors to receiving patients has become a concern as numerous articles about the epidemiology of T. gondii infection in blood donors from different provinces have been published in China. This study aimed to evaluate the seroprevalence of T. gondii infection in Chinese blood donors using a meta-analysis. A total of 40 eligible studies, published from 1986 to 2017 and covering 18 provinces and municipalities were included. Among a total of 49,784 Chinese blood donors, the overall IgG seroprevalence of T. gondii infection was 6.26% (95% CI: 4.62%–8.13%). The highest prevalence was in the Northeast of China and the lowest in Central China. The infection rate increased slowly over the years, but not significantly. A statistically significant correlation was found between the seroprevalence of T. gondii infection and the detection method and educational level (p < 0.01). There was no relationship between age, gender, occupation and blood type and seroprevalence of T. gondii (p > 0.05). The prevalence of antibodies to T. gondii in Chinese blood donors was lower than in other countries, but the risk of transfusion-transmitted toxoplasmosis still exits. More concise methods are still needed to evaluate the possibility of transfusion-transmitted toxoplasmosis from blood donors.
Résumé
La transmission de Toxoplasma gondii des donneurs de sang aux patients receveurs est devenue un sujet de préoccupation car de nombreux articles sur l’épidémiologie de l’infection à T. gondii chez des donneurs de sang de différentes provinces ont été publiés en Chine. Cette étude visait à évaluer la séroprévalence de l’infection par T. gondii chez des donneurs de sang chinois à l’aide d’une méta-analyse. Un total de 40 études admissibles, publiées de 1986 à 2017 et couvrant 18 provinces et municipalités, ont été incluses. Sur un total de 49 784 donneurs de sang chinois, la séroprévalence globale des IgG de l’infection à T. gondii était de 6,26% (IC à 95%: 4,62%-8,13%). La prévalence la plus élevée était au nord-est de la Chine et la plus faible en Chine centrale. Le taux d’infection a augmenté lentement au cours des années, mais pas de manière significative. Une corrélation statistiquement significative a été trouvée entre la séroprévalence de l’infection par T. gondii et la méthode de détection et le niveau d’éducation (p < 0,01). Il n’y avait pas de relation entre l’âge, le sexe, la profession, le type sanguin et la séroprévalence de T. gondii (p > 0,05). La prévalence des anticorps contre T. gondii chez les donneurs de sang chinois est plus faible que dans les autres pays, mais le risque de toxoplasmose transmise par transfusion existe toujours. Des méthodes plus concises sont encore nécessaires pour évaluer la possibilité de toxoplasmose transmise par transfusion chez les donneurs de sang.
