Egypt has high prevalence of hepatitis C virus (HCV) infection and intermediate prevalence of hepatitis B virus (HBV) infection; however, infection prevalence among Egyptian migrants is unknown. Considering the asymptomatic onset and development of disease in chronically-infected patients, many may remain undiagnosed.
To evaluate an HCV- and HBV-screening programme designed to identify undetected infections among first-generation Egyptian migrants in Amsterdam, the Netherlands.
In 2009 and 2010, viral hepatitis educational and screening sessions were established at Egyptian meeting places. Data regarding demographics and HCV risk factors were collected. Chronically infected participants were referred and followed up. Phylogenetic analyses were used to ascertain the geographic origin of infections.
Eleven of 465 (2.4%; 95% CI = 1.3-4.2%) migrants had HCV antibodies; 10/11 were HCV RNA positive. All had genotype 4a, and strains were typical of those of Egypt and the Middle East. Older age and exposure to parenteral antischistosomal therapy (PAT) were significantly associated with HCV. Anti-HBc prevalence was 16.8% (95% CI = 13.7-20.4%); HBsAg prevalence was 1.1% (95% CI = 0.5-2.5%). All had genotype D, typical of those of the Middle East. Most (9/10 HCV; 3/5 HBV) chronic infections were newly diagnosed; four of the HCV-infected individuals started treatment.
Anti-HCV and HBsAg prevalence among Egyptian migrants was lower compared with the general Egyptian population, but higher than the general population of Western countries. Phylogenetic analyses suggest that all infections were from the region of origin. HCV-screening programmes should target first-generation Egyptian migrants, especially those of older age and those who received PAT.
埃及丙型肝炎病毒(HCV)感染率较高,乙型肝炎病毒(HBV)感染率处于中等水平;然而,埃及移民中的感染率尚不清楚。鉴于慢性感染患者疾病的无症状发作和发展,许多患者可能未被诊断。
评估一项 HCV 和 HBV 筛查计划,旨在发现荷兰阿姆斯特丹第一代埃及移民中的未确诊感染。
2009 年和 2010 年,在埃及人聚会场所设立了病毒性肝炎教育和筛查点。收集有关人口统计学和 HCV 危险因素的数据。对慢性感染参与者进行转诊和随访。采用系统发生分析确定感染的地理来源。
在 465 名移民中,有 11 名(2.4%;95%CI=1.3-4.2%)具有 HCV 抗体;10/11 为 HCV RNA 阳性。所有患者均为基因型 4a,且病毒株与埃及和中东地区的典型株一致。年龄较大和接受驱虫剂(PAT)治疗与 HCV 显著相关。抗 HBc 阳性率为 16.8%(95%CI=13.7-20.4%);HBsAg 阳性率为 1.1%(95%CI=0.5-2.5%)。所有患者均为基因型 D,与中东地区的典型株一致。大多数(9/10 HCV;3/5 HBV)慢性感染是新诊断的;4 名 HCV 感染个体开始治疗。
与埃及普通人群相比,埃及移民中的抗-HCV 和 HBsAg 阳性率较低,但高于西方国家的普通人群。系统发生分析表明,所有感染均来自原籍地区。HCV 筛查计划应针对第一代埃及移民,尤其是年龄较大和接受过 PAT 治疗的移民。
