Abstract
Background: Worldwide, there has been a worrying increase in the prevalence of syphilis. Blood banks have a major role in monitoring the trend of these events, despite the bias due to the altruistic donation strategy.
Objectives: To determine the seroprevalence of syphilis and analyse its association with defined risk factors among blood donors at the regional blood center at Hospital Prof. Dr. J. P. Garrahan, period 2016-2022.
Materials and methods: Donor screening was performed with treponemal and non-treponemal tests to determine the prevalence of active and past syphilis. Sociodemographic characteristics of donors were analysed and the association with potential risk factors was assessed.
Results: A total of 72 874 donations were processed during the study period. The overall prevalence of specific anti-Treponema pallidum antibodies was 0.69% (95% CI = 0.63-0.75). Active syphilis seroprevalence was 0.30% (95% CI = 0.25-0.33). Not active syphilis seroprevalence was 0.39% (95% CI = 0.35-0.44). Anti-T. pallidum seroprevalence among first-time donations was 1.26% (95% CI = 1.14-1.38) while in repeat donations it was 0.16% (95% CI = 0.12-0.21). In univariate analysis, we found an association between syphilis and having a history of any sexually transmitted infection (OR: 5.09, 95% CI = 2.20-11.70, p < 0.01) and being first-time donors (OR: 3.48, 95% CI = 1.70-7.09, p = 0.0001).
Conclusion: Although the overall prevalence of syphilis is 0.69%, among repeat donors prevalence as low as 0.16% was found. This demonstrates the need to maintain and improve screening strategies and promotion of voluntary, altruistic and repeat donation.
背景:在世界范围内,梅毒发病率的增长令人担忧。尽管利他主义献血策略会造成偏差,但血库在监测这些事件的趋势方面发挥着重要作用:确定 2016-2022 年期间 J. P. Garrahan 教授医院地区血液中心献血者的梅毒血清阳性率,并分析其与确定风险因素的关联:通过三螺旋体和非三螺旋体检测对献血者进行筛查,以确定活动性梅毒和既往梅毒的患病率。分析了捐献者的社会人口学特征,并评估了与潜在风险因素的关联:研究期间共处理了 72 874 例捐献。特异性抗苍白螺旋体抗体的总体流行率为0.69%(95% CI = 0.63-0.75)。活动性梅毒血清阳性率为0.30%(95% CI = 0.25-0.33)。非活动梅毒血清阳性率为0.39%(95% CI = 0.35-0.44)。首次捐献者的抗苍白螺旋体血清阳性率为1.26%(95% CI = 1.14-1.38),而重复捐献者的阳性率为0.16%(95% CI = 0.12-0.21)。在单变量分析中,我们发现梅毒与任何性传播感染史之间存在关联(OR:5.09,95% CI = 2.20-11.70,P 结论:梅毒与任何性传播感染史之间存在关联(OR:5.09,95% CI = 2.20-11.70,P 结论):虽然梅毒的总体发病率为 0.69%,但在重复捐献者中的发病率却低至 0.16%。这表明有必要保持和改进筛查策略,并推广自愿、利他和重复捐献。
