Analysis on HIV infection status of voluntary blood donors in Chinese Nanjing area from 2003 to 2013 / 中国实验血液学杂志

ABSTRACT

This study was purposed to analyze HIV infections status among the unpaid blood donation population in Chinese Nanjing area from 2003 to 2013, to understand the HIV antibody positive and/or HIV-RNA positive population characteristics in order to provide evidence for recruiting strategy of blood donation without compensation. The whole blood samples of unpaid donors and the platelet donors were tested by ELISA, from June 2010 the NAT test was added for the samples that were ELISA test with unilateral negative. Every HIV reactive sample (HIV-antibody and/or HIV-RNA) was sent to confirm in the Centers for Disease Control and Prevention in Nanjing, including 1 case of enzyme bilateral positive and HIV-RNA reactivity has been sentenced as indeterminacy; another 1 case of enzyme bilateral negative and HIV-RNA reactive was sent to the Centers for Disease Control and Prevention in Jiangsu Province to test nucleic acid quantification to be positive; The unpaid donor HIV screening results from 2003 to 2013 in Chinese Nanjing area were analysed statistically. The results showed that from 2003 to 2013 years 641401 unpaid blood donors were tested,out of them 57 cases were contirmed to be HIV antibody positive (HIV-1),the total positive rate was 8.89/100 000. Since 2010 years, the HIV antibody positive rate increased significantly (P < 0.01), then it was stable until to 2012 years, the HIV antibody positive rate was 15.43/100 000. In the 2013 year, the HIV antibody positive rate was 10.03/100 000. The HIV antiboby positive rates in male and female were 13.25 1. The years of male cases were 18-30 that accounted for 56.14%, and the years of male cases were 31-40 that accounted for 31.58%. The men who first time donated blood were 46 cases and accounted for 80.70%. The men who donated blood again were 11 cases and accounted for 19.30%. The men who donated blood on streets of blood donation accounted for 80.70% and their HIV antibody positive rate was 11.88/100 000. The men who donated blood in the plan organization of donators were 8.78%, and their HIV antibody possitive rate was 2.33/100 000. The HIV antibody positive rate were different in the different times and different donation types, and were statistical significance (P < 0.01). It is concluded that based on the present status of HIV antibldy positive rate in Chinese Nanjing area, the HIV antibody possitive donors are more observed in the first blood donation population, especially in the higher educated young men. This situation or tendency indicates that the voluntary blood donors should be organized or selected from low risk population, and should popularize the knowlege of unpaid blood donation, especiatly the knowlege of AIDS, strengthen cosulting work on the mobile donation points in streets before donating blood, and should establish the cyber-database to ensure blood safety.
