Rapid Testing Algorithm Performance in a Low-Prevalence Environment.

BACKGROUND: The performance of a statewide HIV rapid test algorithm (RTA) in a low-prevalence setting (0.71%) was examined for 3 years. METHODS: An initial rapid screening by HIV-1/2 Ag/Ab Combo test (RT#1) with Ab verification using a second, different rapid test (RT#2) was conducted. Clinic referral was immediate for antigen-only-positive screens. Antibody-positive screens were confirmed by RT#2. Specimens were collected following discordant RTA results (initially Ab-POS by RT#1, but negative on RT#2) and tested in accordance with the current Centers for Disease Control and Prevention/Association of Public Health Laboratories-based HIV diagnostic algorithm supplemented by a quantitative viral load whenever possible. RESULTS: Of 310,785 tests performed, 2400 preliminary positive screens were identified; 2191 (91.8%) confirmed by RT#2. Of 13 Determine Combo AG-POS results identified, only 1 confirmed positive. Of the remaining 196 discordant results, 182 (92.9%) were uninfected, including 13 with AG-POS/AB-POS results. Of 14 true positives (7.1%) identified after discordant RTA results, the average quantitative HIV-1 viral load was 277,385 copies/mL, but 5 (35.7%) of 14 had viral loads <1000 copies/mL. Among the 2191 "presumptive positive" by RTA, 3 false-positive (FP) RTAs were reported (both rapid tests having positive results, while the HIV-1/2 Ag/Ab assay and quantitative HIV-1 viral load showed negative results). CONCLUSIONS: The RTA was effective in predicting true-positive HIV test results and facilitating linkage to care. Discordant results were infrequent. Fingerstick DC Ag detection identified a single early infection. Many discordant cases that were subsequently positive were associated with viral loads <1000 copies/mL.

Effect of a Rapid Test Algorithm on Linkage to Medical Care and Viral Suppression Among New Jersey Residents, 2007 to 2015.

BACKGROUND: Efforts to identify and link human immunodeficiency virus-infected persons to medical care are the first steps to achieving viral suppression. In the United States, the goals are to link 85% of newly diagnosed persons to medical care in 30 days or less and for 80% to become virally suppressed by 2020. Among newly diagnosed residents from 2007 to 2015, in New Jersey, we evaluated the impact of a rapid testing algorithm (RTA) on linkage to medical care and viral suppression. METHODS: This is a retrospective review of data from New Jersey's Enhanced HIV/AIDS Reporting System for residents, newly diagnosed at 13 years or older, from 2007 to 2015. We used survival analysis methods to estimate the proportion of residents and time to linkage to medical care and viral suppression. RESULTS: Of 8508 newly diagnosed residents, 60.3% and 72.3% were linked to medical care in 30 days or less and 90 days or less, respectively; 45.7% achieved viral suppression in 365 days or less. Linkage to medical care in 90 days or less and viral suppression in 365 days or less were more likely among those tested by RTA than laboratory testing. The adjusted hazard ratios for linkage to medical care, in clinical sites were 1.41, (95% confidence interval [CI], 1.22-1.63 and 1.08, 95% CI, 0.97-1.2 in community sites. The adjusted hazard ratios for viral suppression in clinical sites were 1.25 (95% CI, 1.05-1.47 and 1.16, 95% CI, 1.01-1.32, in community sites. CONCLUSIONS: Implementation of a RTA may eliminate barriers to linkage to medical care and viral suppression leading to decreased morbidity, mortality, and transmission.

Annual and durable HIV retention in care and viral suppression among patients of Peter Ho Clinic, 2013-2017.

OBJECTIVES: To determine rates of annual and durable retention in medical care and viral suppression among patients enrolled in the Peter Ho Clinic, from 2013-2017. METHODS: This is a retrospective review of medical record data in an urban clinic, located in Newark, New Jersey, a high prevalence area of persons living with HIV. Viral load data were electronically downloaded, in rolling 1-year intervals, in two-month increments, from January 1, 2013 to December 31, 2019. Three teams were established, and every two months, they were provided with an updated list of patients with virologic failure. Retention and viral suppression rates were first calculated for each calendar-year. After patients were determined to be retained/suppressed annually, the proportion of patients with durable retention and viral suppression were calculated in two, three, four, five and six-year periods. Descriptive statistics were used to summarize sample characteristics by retention in care, virologic failure and viral suppression with Pearson Chi-square; p-value <0.05 was statistically significant. Multiple logistic regression models identified patient characteristics associated with retention in medical care, virologic failure and suppression. RESULTS: As of December 31, 2017, 1000 (57%) patients were retained in medical care of whom 870 (87%) were suppressed. Between 2013 and 2016, decreases in annual (85% to 77%) and durable retention in care were noted: two-year (72% to 70%) and three-year (63% to 59%) periods. However, increases were noted for 2017, in annual (89%) and durable retention in the two-year period (79%). In the adjusted model, when compared to current patients, retention in care was less likely among patients reengaging in medical care (adjusted Odds Ratio (aOR): 0.77, 95% CI: 0.61-0.98) but more likely among those newly diagnosed from 2014-2017 (aOR: 1.57, 95% CI: 1.08-2.29), compared to those in care since 2013. A higher proportion of patients re-engaging in medical care had virologic failure than current patients (56% vs. 47%, p < 0.0001). As age decreased, virologic failure was more likely (p<0.0001). Between 2013 and 2017, increases in annual (74% to 87%) and durable viral suppression were noted: two-year (59% to 73%) and three-year (49% to 58%) periods. Viral suppression was more likely among patients retained in medical care up to 2017 versus those who were not (aOR: 5.52, 95% CI: 4.08-7.46). Those less likely to be suppressed were 20-29 vs. 60 years or older (aOR: 0.52, 95% CI: 0.28-0.97), had public vs. private insurance (aOR: 0.29, 95% CI: 0.15-0.55) and public vs. private housing (aOR: 0.59, 95% CI: 0.40-0.87). CONCLUSIONS: Restructuring clinical services at this urban clinic was associated with improved viral suppression. However, concurrent interventions to ensure retention in medical care were not implemented. Both retention in care and viral suppression interventions should be implemented in tandem to achieve an end to the epidemic. Retention in care and viral suppression should be measured longitudinally, instead of cross-sectional yearly evaluations, to capture dynamic changes in these indicators.

Same-Day Medical Visit Increases Viral Suppression, Peter Ho Memorial Clinic, 2014-2015 and 2016-2017.

Viral suppression (VS) in patients newly diagnosed with HIV is critical to reducing morbidity, mortality, and new transmissions. Rapid initiation of antiretroviral therapy (ART) is a promising model to improve VS, but patients must be seen expeditiously by a prescribing provider. Our retrospective study compared patients achieving VS after introduction of medical visits on the same day as HIV diagnoses from 2014 to 2017. The time to VS was evaluated using survival analysis. Wilcoxon two-sample tests evaluated median times to VS (after diagnosis and ART receipt). When 2016-2017 was compared with 2014-2015, a higher proportion of patients achieved VS (96% and 90%, respectively; p = .0292); the median time to VS decreased to 88 from 101 days after diagnosis and to 44 from 70 days after receipt of ART. As clinicians consider rapid ART initiation, a medical visit on the same day as HIV diagnosis is an intermediate intervention that may improve VS.

Increased proportions of HIV-infected women met cervical cancer screening guideline in 2016.

BACKGROUND: HIV-infected women are five times more likely to develop invasive cervical cancer. Routine screening can detect early signs of cancer and provide an opportunity for treatment. However, suboptimal screening rates are reported in this population. This retrospective study examined the rates of cervical cancer screening in HIV-positive women, conducted according to the current guidelines, from 2014 to 2016 in an inner-city clinic. MATERIALS AND METHODS: We implemented focused scheduling for eligible women by a designated medical assistant. Testing was conducted using Thin Prep™ and Cervista HPV HR™. Chi-square tests and logistic regression models were used to assess predictors of cervical cancer screening in 2016. RESULTS: A total of 360 adult HIV-infected women were active in medical care, as of December 31, 2016. Most were African American (77%) and aged 51-60 years (38%). In 2016, 75% of women met the guidelines for cervical cancer screening, compared to 48% in 2014. There was a significant association between receipt of cervical cancer screening in the prior 3 years and screening in 2016. In an adjusted model, those with a prior screening were 6.88 times (95% CI, 3.47-13.67) more likely to be screened in 2016, compared to those who were never previously screened. CONCLUSION: Focused scheduling and implementation of the updated cervical cancer screening guideline extending the period of rescreening, after 3 yearly negative results or negative Papanicolaou/human papilloma virus testing, resulted in an increased proportion of women meeting the current guideline.

Correlates of Sexually Transmitted Infections among Adolescents Attending Public High Schools, Panama, 2015.

BACKGROUND: Sexually transmitted infections (STIs) are common in adolescents worldwide. Vulnerability to STIs increases with risky sexual practices. This study described the sexual practices, estimated the prevalence of STIs, and identified correlates associated with STIs among participants, enrolled in public high schools, in the District of Panama, Panama. METHODS: A cross sectional study, using multistage cluster sampling, was conducted among participants, aged 14-18 years, enrolled in public high schools, in the District of Panama, Panama City, Panama, from August to November, 2015. Participants completed a self-administered questionnaire and provided biological samples. The samples of those reporting sexual activity (oral, vaginal, and/or anal intercourse) were tested for STIs. Odds ratios were used to identify correlates of STIs in this population. RESULTS: A total of 592 participants were included, of whom, 60.8% reported a history of sexual activity, and 24.4% tested positive for least one STI. STIs were more common in female participants, (33.5%). Compared to those without STIs, higher proportions of those with at least one STI reported ≥3 sexual partners in their lifetime (60.0%) and current sexual activity (76.3%). In the multivariable model, correlates of STI included female participants (Adjusted Odds Ratio (AOR) = 5.8, 95% Confidence Interval (CI) 2.3-14.6) and those who engaged in sexual intercourse with casual partners (AOR = 3.0, 95% CI: 1.2-7.5). CONCLUSIONS: We report a high STI prevalence among adolescents attending public high schools, in the District of Panama. Reported risky sexual practices were common and correlated with STIs. Female participants and those reporting sexual intercourse with casual partners were more likely test positive for at least one STI. Our study identified a need for effective interventions to curb future infections in this population.

An anonymous unlinked sero-prevalence survey of HIVHCV in an urban Emergency Department.

BACKGROUND: In 2002, the sero-prevalence of human immunodeficiency virus-1 (HIV) in the Emergency Department (ED), University Hospital, Newark, New Jersey was 10.4%. Both HIV and hepatitis C virus (HCV) are transmitted by injection drug use (IDU) or sexual contact. However, the degree of concurrent positive HCV antibody status in HIV-infected ED patients is unknown. OBJECTIVES: In this study we determined the sero-prevalence of HIV and HIVHCV in HIV-positive patients in the ED. STUDY DESIGN: A cross-sectional study using an anonymous sero-prevalence survey was conducted from 7/1/2008 to 8/23/2008. Medical records were reviewed and de-identified; remnant blood specimens were also de-identified and tested for HIV antibody, and if positive, HCV antibody. RESULTS: Of 3488 specimens, 225 (6.5%, 95% CI: 5.7-7.3%) were positive for HIV antibody. Seventy-four patients 74/225 (32.9%, 95% CI: 33.8-46.5%) were unaware of their sero-positivity. Forty percent of HIV positive patients (90/225, 95% CI: 33.8-46.5%) were HCV antibody positive. The highest seroprevalence of HIVHCV antibody was among older patients (≥ 45 years), and patients with positive urine toxicology and elevated liver function tests. DISCUSSION: Given the high prevalence of HIV and HIVHCV antibody in the ED, routine testing is important for patients ≥ 45 years with positive urine toxicology and elevated liver function tests.
