Repeat HIV Antibody Testing: Are Persons Who Test Most Frequently at Highest Risk of Seroconversion?
Fernyak S, Page-Shafer KA, Kellogg T, McFarland W, Katz M
Objective: As one-third of HIV tests in the U.S. are in individuals who have previously been tested, we sought to characterize risk for HIV seroconversion among repeat testers using data from San Francisco’s publicly funded HIV Counseling and Testing (C&T) sites.
Methods: Records of HIV tests from 1995-97 (n=57,505 tests) were reviewed; 33,770 (59%) were repeat tests; 22,565 (67%) provided information on previous testing and were included in the analysis. HIV incidence was estimated using results of the current test and the time period to the last reported HIV negative test. A four-level hierarchy of risk behaviors was created by ranking self-reported risk behaviors (e.g. IDU, receptive anal intercourse, heterosexual vaginal sex, etc) according to HIV seroincidence. Repeat testing rates were calculated for each risk level.
Results: moderate-high risk level (HIV incidence 2.0-2.1/100PY) had a repeater rate of 92%, with 5.3 tests/person. The high-risk level (2.6-7.0/100PY) had a repeater rate of 86% with 5.0 tests/person. The rate of repeat testing in the lowest risk level (0.2-05/100PY) was 65%.
Conclusion: The demographic profile of persons with high levels of repeat testing accounts for the largest number of HIV seroconversions. Further, high frequency repeat testers are also those who practicing the highest risk behavior and have the highest incidence of HIV. Contrary to previous reports, findings indicate that repeat testers are not simply the “worried well”, but are indeed at high risk of seroconversion. A high frequency of testing is justified for early HIV diagnosis.
Increased incidence of HIV and evidence of transmission of resistant virus among anonymous test site (ATS) attendees in Santos, Brazil, 1995-1999.

Objectives: To (1) estimate HIV incidence among ATS clients in Santos, Brazil by sensitive/less-sensitive (S/LS) EIA testing; (2) describe risk factors associated with recent infection; and (3) measure the prevalence of antiretroviral (ARV) resistance and subtypes among recent infections.
Methods: We collected sera from 10,725 HIV-infected ATS clients ³ 18 years; 698 (6.5%) were HIV-1+. Recent infections were identified by a positive EIA 3A11 and a negative EIA 3A11-LS (termed HIV+SC) and incidence calculated using a standard algorithm. We also compared demographic and risk behavior in 17 HIV+SC identified in 1999 and comparison groups of HIV- (N=37) and other HIV+ (N=37). We subtyped HIV-1 by synthetic peptides based on the V3 region of HIV gp120. We tested for ARV genotypic resistance by PCR amplification from proviral DNA and genomic sequencing of pol region.
Results: Of 392 HIV+ clients whose samples were available, 44 (11%) were HIV+SC. Annual incidence per 100 py was 1.9%, 1.5%, 1.3%, 2.4% and 3.2%. There were no differences in age, race, marital or educational status among HIV-, HIV+SC and HIV+. 76% of HIV+SC were female; 61.5% had 1 sex partner in the past year. Risk factors for HIV+SC compared to HIV- were female sex (OR 8.0; 95%CI 1.2-52), anal sex (OR 11.5; 95%CI 2.4-55.4), and history of STD (OR 4.2; 95%CI 0.9-19.8). Almost all (97%) of the isolates were subtype B; 56% were the Brazilian variant Br; 2 were C. We found high-level genotypic resistance to AZT in 1/5 HIV+SC (M41L+T215Y). Few accessory mutations and a high level of polymorphism was found at the protease region.
Conclusions: This study documents recent increases in HIV incidence in Santos, Brazil. Recent infections are primarily among females reporting steady sexual partnerships, anal sex and history of STD. We found no non-B or C subtypes. There was evidence of transmission of ARV-resistant virus, pointing strongly to the need for further efforts to monitor this phenomenon in Brazil.
