Introduction: Statistics on the prevalence of donor screening for hepatitis B surface antigen (HBsAg) and anti-hepatitis C virus (anti-HCV) in Jordan are outdated. There are no studies on the prevalence of anti-HIV I/II, anti-human T-cell lymphotropic virus type I and II (anti-HTLV-I/II), or anti-syphilis. Data are also lacking on the prevalence and significance of using anti-HBc screening in Jordan. This study aimed to evaluate the prevalence of transfusion-transmissible infections (TTI) among donors at King Hussein Cancer Center and compare it with neighboring countries and to evaluate the significance of screening for anti-HB core total (anti-HBc) antibodies. Methodology: A retrospective analysis covering the period from 2009 to 2013 was conducted on records of healthy donors. The number of donors was 10,101, 12,694, 13,387, 14,256, and 12,495, respectively. Donors were screened for HBsAg, anti-HBc, anti-HIV I/II, anti-HCV, and anti-HTLV-I/II using ELISA technique, while syphilis antibodies were detected using rapid chromatographic immunoassay. Results: Among 62,933 donors, the prevalence of HBsAg was 0.52%, of anti-HBc was 6.04%, and of anti-HCV was 0.16%. None of the donors were positive for anti-HIV I/II, anti-HTLV I/II, or anti-TP. Conclusions: This study demonstrates that the seroprevalence for HBsAg, anti-HBc, and anti-HCV in Jordan was low compared to neighboring countries. None of the donors were confirmed positive for anti-HIV I/II, anti-HTLV I/II, or anti-TP during the studied period. This study demonstrates the importance of screening for anti-HBc to improve blood and platelet safety and stresses the need to complement it with an algorithm that qualifies reentry of anti-HBc false-positive donors.

A Prospective Study

To study the incidence of human T-cell lymphotropic virus (HTLV) after blood transfusion in Taiwan, serum samples from 699 patients in a prospective study were examined for seroreactivity of anti-HTLV. By an enzyme immunoassay, 9 of the 699 recipients were repeatedly positive. Serial serum samples of these 9 patients were then confirmed with a Western blot analysis and with a polymerase chain reaction (PCR) assay for HTLV-I genome. Four were already positive for anti-HTLV before transfusion, 1 carried antibodies to HTLV-I transiently after transfusion, and only 4 cases had de nova seroconversions. These patients and their family members were called back and tested for HTLV- I genome in the peripheral blood mononuclear cell (PBMC) and plasma. All the serologically positive patients, except the “transient one,” were positive for HTLV sequences in the PBMCs. Viral sequences could also be detected in several serum or plasma samples. In the family members, only the spouse of a pretransfusion-positive patient was infected. These results suggested that approximately 0.6% of the blood recipients were infected by HTLV-I through transfusion in Taiwan, and that the frequency of intrafamilial HTLV-I transmission is low. We also observed the unusual coinfection by both HTLV-I and hepatitis C virus in 2 patients, and superinfection of hepatitis C virus after blood transfusion in 1 HTLV-I carrier. Cases of coinfection suggest a prevalence of both viruses in blood donors and warrant further screening.
