摘要
。自20世纪90年代以来,在沙特阿拉伯王国(KSA)血库的献血者单位中筛查了人类嗜t淋巴病毒I型抗体(抗htlv -I)。HTLV-I是第一个被发现的人类逆转录病毒,它可以自然感染CD4 + T淋巴细胞,并可以通过血液传播或通过母乳中的细胞从母亲传播给婴儿。在大多数情况下,感染是无害的,但可能发展成一种成人t细胞白血病,其中每个肿瘤细胞都携带一种克隆整合的HTLV-I原病毒。本研究的目的是确定KSA Aseer地区献血者中抗htlv - i /II抗体的流行情况,并将结果与KSA不同地区的其他报告进行比较,以及抗htlv - i /II抗体筛选的成本效益。采用酶联免疫吸附试验(ELISA)对从Aseer地区献血者收集的4432个血液单位进行抗htlv - i /II抗体检测。检测单位无血清阳性病例。因此,亚洲地区似乎是HTLV-I/II的非流行区。此外,目前对所有献血者进行抗htlv - i /II筛查的做法应该在整个王国进行审查,因为它似乎不具有成本效益。
Human T Lymphotropic Virus-I (HTLV-I), the Causative Agent of Acute T-Cell Leukaemia/Lymphoma, Is Absent among Blood Donors in Aseer Region, Saudi Arabia
. Since the 1990s, antibodies to human T-lymphotropic virus type I (anti-HTLV-I) have been screened in units of blood donors at blood banks in Kingdom of Saudi Arabia (KSA). HTLV-I was the first human retrovirus to be discovered which naturally infects CD4 + T lymphocytes and can be transmitted through blood transfer or from mother to infant through cells in breast milk. In most cases, the infection is harmless but may develop a type of adult T-cell leukemia in which every tumor cell carries a clonally integrated HTLV-I provirus. The aim of this study was to determine the prevalence of anti-HTLV-I/II antibodies in blood donations at Aseer region, KSA, and to compare the results with other reports from different localities in KSA, as well as the cost effectiveness of anti-HTLV-I/II antibodies screening. A 4432 blood units collected from blood donors at Aseer region were tested for the presence of anti-HTLV-I/II using enzyme-linked immunosorbant assay (ELISA). There was no seropositive case in the tested blood units. Therefore, Aseer Region appears to be a non-endemic area for HTLV-I/II. Also, the current practice of screening all blood donors for anti-HTLV-I/II should be reviewed all over the Kingdom as it does not seem to be cost-effective.
