Abstract
PURPOSE
To evaluate the seropositivity of human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV) and syphilis from blood samples of cornea donors and assess correlation between seropositivity for HIV and syphilis.
METHODS
Retrospective analysis of blood samples of 31,355 cornea donors for HIV, HBV, HCV, and syphilis was performed. Postmortem blood samples were analyzed by a rapid screening test for anti-HIV envelope antibodies against HIV 1 and 2, HBV surface antigen, antibody to HCV and anti-cardiolipin antibodies for syphilis by rapid plasma reagin test.
RESULTS
The overall seropositivity rate was 4.28% (1343/31,355 donors). All positive donors were reactive for a single serological test. The seropositivity rate for HIV was 0.93% (95% CI 0.83-1.04%), for HBsAg was 1.56% (95% CI 1.43-1.7%), for HCV was 1.19% (95% CI 1.08-1.33%) and for syphilis was 0.59% (95% CI 0.52-0.69%). The trends in seropositivity rates showed a decline for three viral markers: HIV (2010, 1.17% to 2018, 0.72%, p = 0.02), HBsAg (2010, 1.98% to 2018, 1.05%, p = 0.0006) and HCV (2010, 1.32% to 2018, 0.43%, p < 0.0001). The seropositivity rates for syphilis showed a progressive increase when compared to baseline (2010, 0.14% to 2018, 1.14%, p < 0.0001). There was no relationship between seropositivity for HIV and syphilis (p = 0.18).
CONCLUSIONS
The overall seropositivity for HIV, HBV, HCV and syphilis was 4.28%. Seropositivity was highest for HBV. The study did not find correlation between seropositivity of HIV and syphilis.
