Background

The transmission of diseases by blood products continues to be a worldwide health problem, especially in Africa. Seroprevalence rates of the Hepatitis B virus (HBV), Hepatitis C virus (HCV), Human Immunodeficiency Virus (HIV), Syphilis, and Coinfection in Angola are poorly documented. This study aims to identify the seroprevalence of markers with positive results for Hepatitis B, C, HIV, Syphilis, and Coinfection in blood donors.

Material and methods

A retrospective study was conducted using a database of positive serological markers for these infections and coinfection in 2734 blood donors traced from 2011 to 2016 in Luanda, Angola. The Chi-Square test (χ2) or Fisher's exact test was used to evaluate serological positivity and donors’ characteristics. A p-value < 0.05 was considered statistically significant.

Results

2734 blood donors aged 18 to 64 (median age 32 ± 9) were screened from 2011 to 2016. 73.9 % of the donors were positive for one Transfusion-Transmitted Infection (TTI), and 5.9 % showed evidence of multiple infections. The overall seroprevalence rate was 50.2 % (1373) for HBV, 20 % (436) for Syphilis, 7 % (191) for HIV, 5.1 % (140) for HCV, and 5.8 % for coinfected donors. 2467 (90 %) were men, and 267 (10 %) were women. We identified 118 (5.8 %) coinfected donors. Of those, 40 (33.9 %) simultaneously presented Hepatitis B virus surface antigen (HBsAg)/Syphilis, 24 (20.3 %) HBsAg/HIV, 22 (18.6 %) HBsAg/HCV, 20 (16.9 %) HIV/Syphilis, 8 (6.8 %) HCV/Syphilis, and 4 (3.4 %) HIV/HCV.

Conclusion

A high transfusion-transmissible infection prevalence was found compared to some countries in Sub-Saharan Africa. Therefore, intensifying the screening for these transfusion-transmitted infections in blood donors is critical to ensure blood safety.

安哥拉罗安达健康志愿者献血者五年内病毒性输血传播感染(HBsAg、抗 HCV、抗 HIV、梅毒)和合并感染的血清阳性率

背景

通过血液制品传播疾病仍然是一个世界性的健康问题,特别是在非洲。安哥拉乙型肝炎病毒(HBV)、丙型肝炎病毒(HCV)、人类免疫缺陷病毒(HIV)、梅毒和合并感染的血清阳性率记录很少。本研究旨在确定献血者中乙型肝炎、丙型肝炎、艾滋病毒、梅毒和合并感染阳性结果的标记物的血清流行率。

材料与方法

使用这些感染和合并感染的阳性血清学标记数据库对 2011 年至 2016 年安哥拉罗安达的 2734 名献血者进行了一项回顾性研究。卡方检验(χ2)或Fisher精确检验用于评估血清学阳性和供体特征。p 值 < 0.05 被认为具有统计显着性。

结果

2011年至2016年,对2734名18岁至64岁(中位年龄32±9岁)的献血者进行了筛查。73.9%的献血者对一种输血传播感染(TTI)呈阳性,5.9%的献血者表现出多种感染的证据。HBV 总体血清阳性率为 50.2%(1373 例),梅毒为 20%(436 例),HIV 为 7%(191 例),HCV 为 5.1%(140 例),合并感染供者为 5.8%。2467 名(90%)为男性,267 名(10%)为女性。我们确定了 118 名(5.8%)合并感染的捐赠者。其中,40 例 (33.9 %) 同时呈现乙型肝炎病毒表面抗原 (HBsAg)/梅毒,24 例 (20.3 %) HBsAg/HIV,22 例 (18.6 %) HBsAg/HCV,20 例 (16.9 %) HIV/梅毒,8 ( 6.8 %) HCV/梅毒,以及 4 (3.4 %) HIV/HCV。

结论

与撒哈拉以南非洲的一些国家相比,输血传播感染患病率较高。因此,加强对献血者输血传播感染的筛查对于确保血液安全至关重要。
