and rubella virus are microorganisms that can cause intrauterine infections and congenital anomalies in the fetus. Data regarding the simultaneous seroprevalence of these infections are not available in Senegal.
This study aimed to determine for the first time the simultaneous seroprevalence of toxoplasmosis and rubella among pregnant women in Dakar.
In this retrospective study, anti- and anti-rubella antibodies were analyzed in the serum samples obtained from pregnant women receiving prenatal care at Military Hospital of Ouakam between 2016 and 2021 using a chemiluminescent microparticle immunoassay for the quantitative determination of immunoglobulin G (IgG) and IgM antibodies to and rubella in human serum.
Overall, data from 2589 women were analyzed. The median age was 29 years (interquartile range: 23.14-34.86). Serum IgG and IgM were positive for with 35.84% and 1.66%, respectively. Rubella seroprevalence was 87.14% and 0.35%, respectively, for IgG and IgM. Seroprevalence of toxoplasmosis increases significantly with age and study period. For rubella infection, the highest seroprevalence rates were noted in the youngest age group and at the end of the study period.
Data from this first-time study regarding simultaneous seroprevalence of toxoplasmosis and rubella among pregnant women in Senegal indicate a continuing high risk of congenital toxoplasmosis and congenital rubella syndrome in Dakar. Further studies are needed to fully assess the efficacy of rubella vaccination in women of childbearing age.
弓形虫和风疹病毒是可导致胎儿宫内感染和先天性异常的微生物。塞内加尔尚无关于这些感染同时血清阳性率的数据。
本研究旨在首次确定达喀尔孕妇中弓形虫病和风疹的同时血清阳性率。
在这项回顾性研究中,采用化学发光微粒免疫分析法对2016年至2021年期间在瓦卡姆军事医院接受产前护理的孕妇血清样本中的抗弓形虫抗体和抗风疹抗体进行分析,以定量测定人血清中针对弓形虫和风疹的免疫球蛋白G(IgG)和IgM抗体。
总体而言,分析了2589名女性的数据。中位年龄为29岁(四分位间距:23.14 - 34.86)。弓形虫血清IgG和IgM阳性率分别为35.84%和1.66%。风疹血清阳性率方面,IgG和IgM分别为87.14%和0.35%。弓形虫病的血清阳性率随年龄和研究时间段显著增加。对于风疹感染,最年轻年龄组和研究期末的血清阳性率最高。
这项关于塞内加尔孕妇中弓形虫病和风疹同时血清阳性率的首次研究数据表明,达喀尔先天性弓形虫病和先天性风疹综合征的风险持续较高。需要进一步研究以全面评估风疹疫苗对育龄妇女的有效性。
