Despite progress made in the prevention of transfusion-transmitted infections (TTI) over the last few years, they continue to be a problem in many parts of the world, particularly in multitransfused patients.
The aim of this study was to estimate the prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV), and to evaluate the screening and vaccination program among our cohort of multitransfused children from Qena, Upper Egypt.
One-hundred children suffering from diseases requiring repeated blood transfusions were included in the study. They were classified into group 1, which included 67 children with thalassemia, and group 2, which included 33 children with hemophilia. Screening for hepatitis B surface antigen, hepatitis B surface antibody, hepatitis B core antibody and antibody to HCV was done using a second-generation enzyme-linked immunosorbent assay technique.
Only 12% of all patients were either acutely or chronically infected with HBV. 46% were immune due to previous vaccination, whereas 39% of patients were not protected from HBV infection. HCV antibodies were positive in 45% of cases. Seventy-eight patients had a complete hepatitis B vaccination in the form of three doses as documented by birth certificate. Thirty-six patients mentioned history suggestive of hepatitis. The prevalence of the studied hepatitis markers was similar in both the thalassemia and hemophilia groups of children.
Transfusion-transmitted hepatitis is still a major problem for multitransfused children in Egypt. More effort is required to reduce the infection rate through proper screening of blood and blood products, strict emphasis on receiving the vaccine, regular follow-up for those children with a hepatitis B antibody titer, and providing booster doses for those in need.
尽管在过去几年中,在预防输血传播感染(TTI)方面取得了进展,但在世界许多地区,它们仍然是一个问题,特别是在多次输血的患者中。
本研究的目的是估计乙型肝炎病毒(HBV)、丙型肝炎病毒(HCV)的流行率,并评估我们来自埃及上埃及基纳的多次输血儿童队列中的筛查和疫苗接种计划。
本研究纳入了100名患有需要反复输血疾病的儿童。他们被分为第1组,其中包括67名地中海贫血儿童,以及第2组,其中包括33名血友病儿童。使用第二代酶联免疫吸附测定技术对乙型肝炎表面抗原、乙型肝炎表面抗体、乙型肝炎核心抗体和丙型肝炎病毒抗体进行筛查。
所有患者中只有12%急性或慢性感染HBV。46%由于先前接种疫苗而具有免疫力,而39%的患者未受到HBV感染的保护。45%的病例中丙型肝炎病毒抗体呈阳性。根据出生证明,78名患者接受了三剂完整的乙型肝炎疫苗接种。36名患者提到有肝炎病史。在地中海贫血和血友病儿童组中,所研究的肝炎标志物的流行率相似。
输血传播的肝炎仍然是埃及多次输血儿童面临的一个主要问题。需要做出更多努力,通过适当筛查血液和血液制品、严格强调接种疫苗、对乙型肝炎抗体滴度的儿童进行定期随访以及为有需要的儿童提供加强剂量来降低感染率。
