Seroepidemiologic Evaluation of HIV Scanning and Verification Datas During The Period of 2015-2018

The aim of this study is to retrospectively discuss the patients’ HIV scanning and verification test results along with their demographics, who were admitted to Istanbul UniversityCerrahpaşa Cerrahpaşa Medical Faculty Medical Microbiology Laboratory Center Serology/ ELISA division with the suspicion of HIV infection or pre-op serologic scanning. In addition, we aimed to compare HIV seroprevalence with the data of the previous period of our center. HIV-1/2 antibody +P24 antigen (HIV -1/2 Ab/Ag) was studied routinely with ELISA method, and as a second repeat test chemiluminescence immunoassay (CLIA) method was used. The verification of the patient sera, which showed repetitive reactivity after HIV -Ab/Ag test, was studied with line immunoassay (LIA) method. Retrospectively, in the 144,256 cases which was studied in the past 4 years, there were 366 (0.25 %) anti HIV-1/2 repeated reactivity. From repeated reactivity serum samples, LIA testing was performed to confirm 180 serum samples, excluding those previously confirmed, and 158 (87.8 %) were positive. All of these specimens showed sgp120 and gp41 band positivity, therefore HIV1 positivity was confirmed. These retrospective data from one center on HIV seroprevalence for a 4-year period are in agreement with other Turkish studies. Rate of HIV prevalence in Istanbul, which is a cosmopolit and immigrant receiving city, was found to have increased compared to the last period of time, which was only 0.06 %.
