Before 2014, the only test used for anonymous voluntary human immunodeficiency virus (HIV) screening at public health centers (PHCs) in the Republic of Korea was an enzyme-linked immunosorbent assay (ELISA), which takes around 3 days to obtain results. In 2014, to encourage voluntary anonymous HIV screening tests, the Seoul Metropolitan Government adopted a rapid HIV screening test at PHCs. The rapid HIV screening test was introduced at four PHCs in 2014 and all 25 PHCs after 2015. We compared the numbers of HIV screening tests and confirmed positive individuals before and after introduction of the rapid HIV screening test. In 2012–2013, before the introduction of rapid HIV screening test, an average of 330 HIV screening tests were performed monthly (355 in 2012 and 305 in 2013) and 69 individuals were confirmed to have HIV in 2012 and 93 in 2013. After the introduction of the rapid HIV screening test, anonymous voluntary HIV screening increased to a monthly average of 447 tests in 2014, 2099 in 2015, and 2409 in 2016. These identified 38 new cases in 2014, 116 in 2015, and 143 in 2016. Adoption of the rapid HIV screening test has increased the number of HIV screening tests and confirmed cases.

Abstract Background Approximately 1 in 5 Canadians with HIV are unaware of their status. In many provinces and especially rural communities, barriers to HIV testing include lack of access, privacy concerns, and stigma. The availability of HIV point-of-care testing (POCT) is limited across Canada. Pharmacists are well positioned to address barriers by offering rapid HIV POCT and facilitating linkage to care. Methods We will use a type-2 hybrid implementation-effectiveness design to assess a pilot HIV POCT model in one urban and one rural pharmacy in each of two Canadian provinces over 6 months. In this feasibility trial the research aims include developing and assisting pharmacies in implementing the model, evaluating processes/determinants of program implementation, evaluating the model’s effects on client outcomes, preferences, and testing satisfaction. Using a community-based research approach, the research team will engage community stakeholders in each province including individuals with lived experience to inform the development of the pharmacy-based HIV testing model and support the research team throughout the study. A multipronged promotion campaign will be used to promote the study and facilitate recruitment. The pharmacy-based testing model will include pre/post-test counseling and linkage to care plans in addition to pharmacist-administered HIV POCT. Pharmacists will complete a comprehensive training program prior to implementing the testing model. Client demographics and satisfaction will be assessed by surveys and interviews. Pharmacists will document time required for testing and participate in a post-study focus group to discuss barriers/enablers. Implementation will be assessed qualitatively and quantitatively. The process of developing and implementing the model will be described using qualitative data and a logic model. Acceptability and barriers/enablers will be examined qualitatively based on survey responses. A preliminary costing assessment will consider the client, pharmacy, and government perspectives. Discussion The results of this pilot will inform modifications to the HIV POCT model to optimize effectiveness and increase scalability. The study has national importance, providing valuable information on improving access to HIV testing. Future applications of this research may expand the role of pharmacists in offering POCT for other sexually transmitted/bloodborne infections as tests become available in Canada.

In 2015, rapid human immunodeficiency virus (HIV) testing was implemented in all 25 public health centers in Seoul. During March and December 2015,20,987 rapid HIV tests were performed, of which 116 (0.5%) were positive. Compared to those of the period before application of the rapid HIV test in place of conventional enzyme immunoassay method, the number of HIV tests performed and the number of positive results increased by sevenfold and twofold, respectively. In conclusion, expansion of the provision of rapid HIV tests in public health centers increased the number of voluntary HIV tests. [ABSTRACT FROM AUTHOR]

Objectives HIV rapid antibody tests are widely used in Africa, but dual testing sometimes produces discordant results. It is not clear if discordant rapid HIV tests should always heighten suspicion by frontline health workers that early HIV infection is present. Some studies have reported that discordant rapid tests have value for identifying early HIV infection in high HIV prevalence populations. It is not known if rapid test performance influenced this conclusion, or if this observation will hold true for low HIV prevalence populations. We therefore explored the occurrence of discordant rapid HIV tests in a low-resource community. Methods A cross-sectional sample of HIV status-unaware adults with recent exposure to unsafe sex was assessed using a validated risk-based tool (University of North Carolina (UNC)-Malawi Risk Screening Score) for acute HIV infection. Participants received rapid testing with Determine™ HIV 1/2 and Uni-Gold™ HIV assays, plus plasma HIV-1 antigen testing with the COBAS® Ampliprep/ COBAS® Taqman® HIV-1 assay, followed by western blot in those with detected HIV-1 antigen. Results Of 408 participants, 1.0% were confirmed to have established HIV infection. The discordance between rapid tests at initial screening was 2.45 and 2.94% when the two assays were used sequentially and simultaneously, respectively. Discordant rapid tests were strongly associated with risk scores > 2 [odds ratio ( OR) 10.88; 95% confidence interval ( CI) 2.35-50.43], and with detected HIV-1 RNA ( OR 26.06; 95% CI 3.91-173.60). Conclusions When the sample occurrence of discordance between the first and second tests is below 5%, discordant rapid tests in an adult with sexual risk behaviour should trigger strong suspicion of early HIV infection in low HIV prevalence populations.

Introduction: In the era of ambitious HIV targets, novel HIV testing models are required for hard-to-reach groups such as men, who remain underserved by existing services. Pregnancy presents a unique opportunity for partners to test for HIV, as many pregnant women will attend antenatal care (ANC). We describe the views of pregnant women and their male partners on HIV self-test kits that are woman-delivered, alone or with an additional intervention. Methods: A formative qualitative study to inform the design of a multi-arm multi-stage cluster-randomized trial, comprised of six focus group discussions and 20 in-depth interviews, was conducted. ANC attendees were purposively sampled on the day of initial clinic visit, while men were recruited after obtaining their contact information from their female partners. Data were analysed using content analysis, and our interpretation is hypothetical as participants were not offered self-test kits. Results: Providing HIV self-test kits to pregnant women to deliver to their male partners was highly acceptable to both women and men. Men preferred this approach compared with standard facility-based testing, as self-testing fits into their lifestyles which were characterized by extreme day-to-day economic pressures, including the need to raise money for food for their household daily. Men and women emphasized the need for careful communication before and after collection of the self-test kits in order to minimize the potential for intimate partner violence although physical violence was perceived as less likely to occur. Most men stated a preference to first self-test alone, followed by testing as a couple. Regarding interventions for optimizing linkage following self-testing, both men and women felt that a fixed financial incentive of approximately USD$2 would increase linkage. However, there were concerns that financial incentives of greater value may lead to multiple pregnancies and lack of child spacing. In this low-income setting, a lottery incentive was considered overly disappointing for those who receive nothing. Phone call reminders were preferred to short messaging service. Conclusions: Woman-delivered HIV self-testing through ANC was acceptable to pregnant women and their male partners. Feedback on additional linkage enablers will be used to alter pre-planned trial arms. [ABSTRACT FROM AUTHOR]

Background The Trinity Biotech Uni-Gold HIV test (Uni-Gold) is often used as a supplementary rapid test in testing algorithms. Objective To evaluate the operational performance of the Uni-Gold as a first-line screening test among gay and bisexual men (GBM) in a setting where 4th generation HIV laboratory assays are routinely used. Study design We compared the performance of Uni-Gold with conventional HIV serology conducted in parallel among GBM attending 22 testing sites. Sensitivity was calculated separately for acute and established infection, defined using 4th generation screening Ag/Ab immunoassay (EIA) and Western blot results. Previous HIV testing history and results of supplementary 3rd generation HIV Ab EIA, and p24 antigen EIA were used to further characterise cases of acute infection. Results Of 10,793 specimens tested with Uni-Gold and conventional serology, 94 (0.90%, 95%CI:0.70–1.07) were confirmed as HIV-positive by conventional serology, and 37 (39.4%) were classified as acute infection. Uni-Gold sensitivity was 81.9% overall (77/94, 95%CI:72.6–89.1); 56.8% for acute infection (21/37, 95%CI:39.5–72.9) and 98.2% for established infection (56/57, 95%CI:90.6–100.0). Of 17 false non-reactive Uni-Gold results, 16 were acute infections, and of these seven were p24 antigen reactive but antibody negative. Uni-Gold specificity was 99.9% (10,692/10,699, 95%CI:99.9–100.0), PPV was 91.7% (95%CI:83.6–96.6) and NPV was 99.8% (95%CI:99.7–99.9), respectively. Conclusions In this population, Uni-Gold had good specificity and sensitivity was high for established infections when compared to 4th generation laboratory assays, however sensitivity was lower in acute infections. Where rapid tests are used in populations with a high proportion of acute infections, additional testing strategies are needed to detect acute infections. [ABSTRACT FROM AUTHOR]

Background and objective The rapid test study was a real-time comparison of point-of-care (POC) HIV tests to determine their abilities to detect early HIV infection. Study design Men and transgender persons reporting sex with men in the prior year were recruited at the Public Health—Seattle & King County STD Clinic, Gay City Health Project, and University of Washington Primary Infection Clinic. Study tests included the OraQuick ADVANCE Rapid HIV-1/2 Antibody Test performed on oral fluids and tests performed on fingerstick whole blood specimens including OraQuick, Uni-Gold Recombigen HIV test, Determine HIV-1/2 Ag/Ab Combo, and INSTI HIV-1 Rapid Antibody Test. Specimens from subjects with negative results were sent for EIA and nucleic acid amplification testing. McNemar's exact tests compared the numbers of HIV-infected subjects detected. Results Between February 2010 and August 2014, there were 3438 study visits. Twenty-four subjects had discordant POC results with at least one reactive and one non-reactive test, including one subject with a reactive Determine p24 antigen. OraQuick performed on oral fluids identified fewer persons compared to all fingerstick tests. OraQuick performed on fingerstick whole blood detected fewer persons compared to the Determine Combo antibody component ( p = .008) and Combo overall ( p = .004), and there was a trend when compared to INSTI ( p = .06). The Determine Combo specificity was 98.99%. Conclusions As reported by others, Determine Combo underperforms compared to laboratory-based testing, but it did detect one acute infection. If these results are validated, the specificity of Determine Combo may limit its usefulness in populations with lower HIV incidence. [ABSTRACT FROM AUTHOR]

OBJETIVOS: determinar o valor preditivo positivo de um teste rápido para anticorpos contra o HIV denominado DetermineTM (Abott) em gestantes internadas em trabalho de parto entre 1° de agosto de 2001 e 5 de outubro de 2002. MÉTODOS: foram incluídas neste estudo as parturientes que não haviam sido submetidas a exames para a detecção do HIV durante a gestação ou que não apresentavam os resultados disponíveis no momento da internação. A amostra de sangue foi colhida no momento da internação, na sala de admissão, e o teste rápido foi realizado e comparado com o padrão ouro (ELISA e Western blot). RESULTADOS: entre as 298 gestantes avaliadas, o teste rápido foi positivo em 16 pacientes (5,3%). Os resultados foram confirmados pelos testes de ELISA e Western blot em 12 pacientes (4%). Todos os exames negativos foram avaliados pelos testes ELISA e Western blot. O teste apresentou sensibilidade de 100%, especificidade de 98%, valor preditivo positivo de 75% e valor preditivo negativo de 100%. CONCLUSÕES: estes dados mostram o valor do teste rápido para a detecção de infecção por HIV em situações de emergência, como o parto, de gestantes não testadas previamenteOBJECTIVE: to evaluate the sensitivity and specificity of a rapid antibody HIV test (DetermineTM - Abott) for women in labor between August 1, 2001, and October 5, 2002. METHODS: all parturient women who had not been tested for the detection of HIV during pregnancy or had the result of an HIV test not available at admission were included in the present study. Blood samples were collected at the moment of admission, and the rapid test was carried out and compared with the gold standard (ELISA and Western blot). RESULTS: in 298 pregnant women assessed, the rapid test was positive in 16 (5.3%), and the results were confirmed by ELISA and Western blot in 12 cases (4%). All negative results were confirmed by the ELISA and Western blot tests. CONCLUSIONS: the test presented 100% sensitivity, 98% specificity, 75% positive predictive value, and 100% negative predictive value. These data show the importance of the rapid test for the detection of HIV infection in emergencies, such as imminent delivery of non-previously tested pregnant women.

Data regarding the efficacy of Rapid HIV tests (RHTs) in detecting non-B subtype HIV-1 are limited. We evaluated the sensitivity of the INSTI® test for the detection of HIV-1 antibodies for the diagnosis of HIV-1 non-B subtypes and recombinant variants. We identified adults with HIV-1 infection due to non-B subtypes and recombinant variants. The participants were re-tested with INSTI® test. We included 258 patients. Overall, the INSTI® test sensitivity was 98.4% (95%CI: 96.9-99.9%). For the major CRF_02AG subtype, the sensitivity was 99.0% (95%CI: 97.1-100%). The HIV INSTI® test is reliable for the detection of various non-B HIV-1 antibodies. J. Med. Virol. 88:180-183, 2016. © 2015 Wiley Periodicals, Inc. [ABSTRACT FROM AUTHOR]

Background: Accurate HIV testing in pregnancy is critical to the prevention of mother to child transmission of HIV infection and linkages to other preventive strategies. Aims and objectives: This study determined the sensitivity, specificity negative and positive predictive value of serial rapid testing of HIV among pregnant women in Nnewi, south east Nigeria. Methodology: This was a comparative descriptive study conducted over a 4-month period. Serial rapid testing algorithm was compared with conventional ELISA testing after obtaining informed consents from the pregnant women. All positive and discordant results were confirmed with western blot HIV test. Participants also completed a questionnaire. Data analysis was done using SPSS version 20. Result: A total of 166 pregnant women participated in this study. The mean age of the participants was 29 ± 4.3 years. The HIV prevalence was highest in the 25–29 years category. This was also the modal age category. Majority of the women were multiparous. The prevalence of HIV infection was 12 %. The sensitivity, specificity, negative and positive predictive value of serial rapid HIV testing was 95, 100, 99.3 and 100 % respectively. Conclusion: The sensitivity of the serial rapid test algorithm was high but still lower than the WHO recommended 99 % and above. The 100 % specificity and positive predictive value makes it a good diagnostic test strategy. There is need for regular review of HIV test kits and policy. [ABSTRACT FROM AUTHOR]

Bichat Hospital's free and anonymous Voluntary Counseling and Testing centre in Paris is widely visited, with a high rate of HIV-positive diagnosis. This study proposed, in this centre, to describe the HIV newly-diagnosed patients over an 8-year period and to determinate risk factors for failure to return for a positive result. Higher risk for failure to return was found among the heterosexual subjects regardless of their socio-economic background. [ABSTRACT FROM AUTHOR]

Summary: Objectives: To describe the population targeted for the rapid HIV testing program delivered via socio-culturally adapted services in primary care centers and to assess factors associated with uptake of first-time testing. Methods: This was a descriptive cross-sectional study. We analyzed consultations between April 29, 2010 and May 31, 2012. We assessed the differences in age, origin, education, and sexual history between men who have sex with men (MSM), heterosexual men (HM), and women, using a two-sided independent t-test and Chi-square statistics. Factors associated with first-time testing were analyzed by logistic regression. Results: Of 1940 consultations, 45.1% were HM, 25.4% MSM, and 29.5% women; 35.4% were immigrants, 2.5% were or had been sex workers, and 15.4% had visited one. The test was reactive in 2.1%. Up to 44.2% had never been tested. The probability of being tested for the first time increased in HM, women, populations from the Indian Subcontinent, those with no casual sexual partners, those whose partner's serostatus was unknown, and those with no history of other sexually transmitted infections. Conclusions: This program managed to reach a high proportion of vulnerable people. First time HIV testing rates were high. [ABSTRACT FROM AUTHOR]

Objectives To assess:1) if HIV screening with rapid tests in neighbourhoods with a substantial African community is feasible and acceptable among GPs and patients; 2) HIV seroprevalence. Methods Multicenter prospective study with 10 trained physicians. Use of HIV standard test and INSTI Ultrarapid test. Inclusion criteria: MSM, sex worker, multiple sexual partners, having returned or coming from a country with high HIV prevalence, IVDU, Indicator conditions as defined by HIV Indicator Diseases across Europe Study, having an AIDS-defining illness, having had a recent pregnancy or abortion; or presenting other risks. Results From August 2010 to August 2011, 10 trained GPs offered an HIV test to 224 patients: 51% ♀, 48% ♂, 43% Caucasians, 45% Africans. Inclusion criteria: 32% 'high risk group', 9% returning from an endemic country, 29% with an indicator condition; 12 patients (6%) refused the standard test. The INSTI was offered to 217(97%), 197 performed with 2 reactive rapid tests confirmed. The seroprevalence according to ethnic origin was 0% among Caucasians and 2.2% among Africans and was 1.5% among patients with an indicator condition. 1087 consecutive consultations of the same GPs were recorded: 42% patients had ≥1 inclusion criteria among which 41% of offered tests, that is to say 59% of 'missed opportunities'. The reasons for not offering the test as recorded for 55% of patients:'not indicated' 44.5%, 'no time' 33%, 'impossible to propose' 15%, test completed previously 11%, known HIV-positive 4%. Conclusions Standard and rapid tests are well received by patients but were usually not offered by doctors who have been trained. [ABSTRACT FROM AUTHOR]

Thirty-one gay and bisexual men were interviewed on the acceptability, potential use, benefits and limitations of rapid self-testing for HIV in Australia. The majority of men supported the introduction of rapid self-testing, and would be likely to, or would use the tests for home use. However, most reported they would use them for interim testing and not to replace conventional blood testing at health services as they could not detect other sexually transmitted infections or provide the professional expertise and support provided at health services.

Background, The yield of screening for acute HIV infection among general medical patients in resource-scarce settings remains unclear. Our objective was to evaluate the strategy of using pooled HIV plasma RNA to diagnose acute HIV infection in patients with negative or discordant rapid HIV antibody tests in Durban, South Africa. Methods, We prospectively enrolled patients with negative or discordant rapid HIV antibody tests from a routine HIV screening programme in an out-patient department in Durban with an HIV prevalence of 48%. Study participants underwent venipuncture for pooled qualitative HIV RNA, and, if this was positive, quantitative RNA, enzyme immunoassay and Western blot (WB). Patients with negative or indeterminate WB and positive quantitative HIV RNA were considered acutely infected. Those with chronic infection (positive RNA and WB) despite negative or discordant rapid HIV tests were considered to have had false negative rapid antibody tests. Results, Nine hundred and ninety-four participants were enrolled with either negative (n5976) or discordant (n518) rapid test results. Eleven [1.1%; 95% confidence interval (CI) 0.6-2.0%] had acute HIV infection, and an additional 20 (2.0%; 95% CI 1.3-3.1%) had chronic HIV infection (false negative rapid test). Results, Nine hundred and ninety-four participants were enrolled with either negative (n5976) or discordant (n518) rapid test results. Eleven [1.1%; 95% confidence interval (CI) 0.6-2.0%] had acute HIV infection, and an additional 20 (2.0%; 95% CI 1.3-3.1%) had chronic HIV infection (false negative rapid test). Conclusions, One per cent of out-patients with negative or discordant rapid HIV tests in Durban, South Africa had acute HIV infection readily detectable through pooled serum HIV RNA screening. Pooled RNA testing also identified an additional 2% of patients with chronic HIV infection. HIV RNA screening has the potential to identify both acute and chronic HIV infections that are otherwise missed by standard HIV testing algorithms. [ABSTRACT FROM AUTHOR]

Rapid HIV antibody tests, which provide results within 15-60 minutes, can help reduce the number of unrecognized infections by improving access to testing facilities and increase the number of people tested who know their results. After an acceptability study, rapid HIV testing was first implemented in Catalonia in 2007 within the community-based Voluntary Counselling and Testing sites network. One year after implementation, an increase of 102.9% has been observed in the number of tests performed, ranging from 8.4% to 328.3% according to the site. Despite the important immediate impact of rapid HIV testing on the number of tests performed, there was no significant change in the proportion of tests that were positive. Rapid HIV testing can help increase access to testing, but it should be complemented with specific outreach programmes targeting the most vulnerable subgroups. [ABSTRACT FROM AUTHOR]

This study evaluated an obstetrical program using rapid HIV testing for the prevention of mother-to-child HIV transmission (MTCT) in Baja California, Mexico. Between 2003 and 2005, 45 women in labor and 17 prenatal care women were HIV infected. Among labor patients, 14 (31%) delivered by cesarean section compared with 17 (100%) prenatal care patients (P < .001). Intravenous maternal zidovudine (ZDV) and infant oral ZDV were more frequently administered in prenatal care compared to labor patients: 94% versus 33% (P < .001) and 100% versus 79% (P < .001), respectively. All prenatal care women received combination therapy. All 10 HIV-infected infants were in the labor group, resulting in a MTCT rate of 23% (95% confidence interval [CI] 9.5-34.8) compared to 0% (95% CI 0-1.8; P < .001) among the prenatal care group. Five (50%) of the HIV-infected infants had an AIDS diagnosis and 2 (20%) died within 18 months of birth. Women diagnosed during labor had a high HIV MTCT and poor postnatal outcome.

We validated rapid HIV tests among pregnant women in a clinical setting. Field testing was performed using First Response 1,2,3 or Standard Diagnostic and Pareekshak tests. Results were confirmed by third generation HIV ELISA. Discordant or negative, specimens were confirmed by RNA PCR and a fourth generation ELISA test. Sensitivity and specificity were 94.5% (CI: 85.8–98.2) and 100% for First Response; 87.5% (CI: 46.7–99.3) and 100% (CI: 87.7–100%) for Standard Diagnostic and 90.2% (CI: 81.2–95.4) and 100% (CI: 98–100%) for Pareekshak. These sensitivities were lower than laboratory validation which approached 100%. The low-field sensitivity results have implications for Prevention of Mother-to-Child Transmission services.

We estimated the HIV risk reduction that could be attained by using a rapid HIV home test (HT) to screen sexual partners versus using condoms in different proportions of anal intercourse (AI) occasions among men who have sex with men (MSM). Special attention was paid to the role of the window period during which infected cases go undetected. Our results show that if MSM engage in AI without condoms following a non-reactive HT result, they have lower chances of becoming infected by someone still in the window period than by following heuristics and using condoms inconsistently. For MSM who do not use condoms, use of HT as a screening device may be a useful risk reduction strategy. This advantage increases with higher HIV population prevalence. With higher HIV incidence, this strategy will not provide any advantage if condoms are used in as little as one out of four occasions. [ABSTRACT FROM AUTHOR]

In this study, the RESPECT-2, an HIV risk reduction intervention developed by the Centers for Disease Control and Prevention, was translated into Spanish and culturally adapted to the Puerto Rican population. A new intervention emerged called the RReduC-PR (Risk Reduction Counseling-Puerto Rico). This instrument allows the assessment of sexual behaviors and development of risk reduction plans. Women from three distinct risk behavior groups participated: women recruited from a community-based organization (CBO), which includes street sex workers, crack users, and sexual partners of intravenous drug users; participants from a sexually transmitted infection (STI) clinic; and participants from a family planning clinic (FPC) in Puerto Rico. As part of the RReduC-PR, participants were provided counseling before and after a rapid HIV test to explore their attitudes about sexual behaviors. At baseline, all participants from the FPC reported having monogamous relationships (100%), as compared with the participants from the STI clinic (70%) and those from the CBO (20%). STI risk-reduction behaviors varied by site. Most of the participants acknowledged risk behaviors that may have exposed them to HIV. They did not use condoms, or used them inconsistently, even though acquiring HIV was a great concern for them. Most regarded a positive HIV diagnosis as a negative event. Their attitudes toward an HIV diagnosis varied by site. The groups varied in the perception of risk behaviors, knowledge, and concerns. These findings provide useful information for future risk-reduction interventions with these women. [ABSTRACT FROM AUTHOR]

The aim of this study was to evaluate the performance of the rapid antibody test Determine® HIV-1/2, in pregnant women at Tijuana General Hospital. Pregnant women seeking prenatal care or admitted in labour had blood drawn for a rapid HIV test (Determine® HIV-1/2), enzyme immunoassay (EIA) and Western blot. Between March and November 2003, 1068 women in labour and 1529 women in prenatal care were enrolled. The sensitivity, specificity, positive and negative predictive values were 100%, 99.8%, 77% and 100%, respectively. For women in labour, the mean time between blood collection and rapid test results was 92 minutes (range: 20–205 minutes) compared with 41 hours (range 24–120 hours) for HIV EIA (P = 0.012). All HIV-exposed infants received oral zidovudine. These findings indicate that the rapid test Determine® HIV-1/2 has a high sensitivity and specificity in pregnant women. Rapid HIV testing greatly diminishes the time to diagnosis and enables prompt intervention with antiretrovirals at delivery. [ABSTRACT FROM AUTHOR]

Early testing strategies such as human immunodeficiency virus (HIV) DNA and RNA assays have become popular, cheaper and reliable, however the measures of success of Prevention of Mother-to-Child Transmission (PMTCT) programs in predominantly breastfeeding populations often depend on long term follow-up and HIV testing of children. Diagnosis in PMTCT programs in resource-poor countries therefore remains dependent on serological assays. The use of rapid HIV tests in perinatal HIV diagnosis, as recommended by the WHO, was based on the sensitivity and specificity of the enzyme-linked immuno-assay (ELISA) in children and not guided by an independent evaluation of rapid tests. For the purpose of ensuring a reliable diagnosis of perinatal HIV infection in predominantly breastfed children and largely resource-poor settings in Sub-Saharan Africa, we evaluated a HIV rapid test against the ELISA in serial plasma samples. We tested stored plasma samples for HIV antibodies, using a rapid test (Abbott Determine HIV1/2, Abbott Diagnostics, Wiesbaden, Germany) from a cohort of children between 12 and 18 months of age, enrolled in the PETRA (perinatal transmission) study at the Durban site, and compared to pre-determined real-time ELISA results. Using the ELISA results at 18 months as gold standard, the sensitivity of the ELISA at 12 and 15 months was 100% (95% CI 79–100), and specificity improved from 90.4% (95% CI 86–94) at 12 months to 99.5% (95% CI 97–100) at 15 months. The sensitivity of the rapid HIV test when compared to ELISA results at 18 months was 100% (95% CI 46–98) at 12 and 15 months, and the specificity was 89% (95% CI 80–94) and 99% (95% CI 92–100) at 12 and 15 months respectively. The negative predictive values for the rapid test at 12, 15 and 18 months were 100% (95% CI 94–100). Using the 18 month ELISA as the gold standard, the rapid test at 12 and 15 months demonstrated similar specificities to the corresponding ELISA tests. We concluded that the sensitivity and specificity of the rapid HIV test remained optimal (100%) for the diagnosis of HIV infection in children at 18 months. The earlier use of a rapid test at 15 months correctly excluded HIV infection in 99% of the children. Any earlier use of rapid tests without subsequent confirmation could result in an estimated 10% or more children misdiagnosed as HIV infected. [ABSTRACT FROM AUTHOR]

The article presents a study on pregnant women to evaluate counseling and rapid HIV testing acceptance and to determine associated risk factors for HIV infection in Baja California, Mexico. Pregnant women attending Tijuana General Hospital who participated in the study had rapid HIV tests. The authors suggest that findings indicate wide acceptance of HIV counseling and testing. And it was found that HIV seroprevalence was higher among pregnant women at Tijuana General Hospital.

Novel HIV testing strategies may improve the uptake of the test. The aim of the present study was to investigate the uptake of HIV testing during Birmingham Pride events in 2009 and 2010. The project was a collaboration between Whittall Street Clinic and Healthy Gay Life. This was a nurse-delivered service that was offered for nine hours each day during the events (total of 36 hours in two years). The OraSure™ assay for HIV and syphilis testing was used. A total of 405 men visited our marquee during the 2009 (n = 201) and 2010 (n = 204) events. A total of 398 (98%) men accepted HIV testing during the events in 2009 and 2010. Six men (1.5%) were HIV-positive, an incidence of 37.7 cases per 10,000 persons perday. The uptake of syphilis testing was similarly high; 390 (96%) individuals agreed to be tested and one (0.5%) patient was diagnosed with syphilis. The uptake of HIV testing during the Pride event was high. Pride events provide a unique opportunity for testing undiagnosed HIV-infected patients. HIV testing should be provided in other cities during Pride events. [ABSTRACT FROM AUTHOR]

Objective:This study aimed to examine the false positive rate of the OraQuick rapid human immunodeficiency virus (HIV) test compared with the ELISA test in pregnant patients of low socioeconomic status.Study Design:Blood samples from pregnant patients collected between 10 February 2005 and 1 June 2005 were tested with HIV ELISA and OraQuick rapid HIV tests. The positive predictive values of both tests were calculated.Result:Of 910 patients, 14 (1.5%) patients had a positive HIV ELISA test, with only 5 patients confirmed for HIV. The positive predictive value for the ELISA test was 35.7% compared with 100% for the OraQuick rapid test.Conclusion:In a predominantly low socioeconomic Hispanic patient population with a 0.5% HIV prevalence, false positive HIV testing is lower for the OraQuick rapid HIV test compared with the HIV ELISA test. Implementation of the rapid HIV test would mitigate the emotional distress and unnecessary intrapartum and neonatal zidovudine treatments associated with false positive HIV testing.

Background 357 million people between the ages of 19 and 49 are infected each year with a sexually transmitted infection (STI). Wuhan, China is a unique setting for STI intervention as it has over 900,000 college students, a population at high risk for contracting HIV. Cultural attitudes toward premarital sex and homosexuality and poor sexual education are barriers to lowering STI rates. Additionally, 90% of Chinese healthcare is provided at large public hospitals with minimal privacy. Anonymous STI screening outside of the public hospital setting is highly desired by young adults and MSM populations. Methods Study investigators partnered with dating app Blued to advertise a nontraditional testing site where high-risk individuals were offered anonymous STI/HIV screening. With the assistance of the regional CDC and a community-based organization (CBO), rapid STI results were provided in a convenient and nonjudgmental setting. Information on sexual behavior and knowledge of STIs was surveyed for future public health interventions. Results Of 200 individuals screened for HIV, syphilis, gonorrhea, and chlamydia, 51 (25.5%) had a positive test result. Over 10% of rectal and pharyngeal tests were positive, compared with 1% of urine tests. 3/200 (1.5%) of had positive rapid HIV test results; all were connected to treatment. Among 41 (20.5%) who learned about the study through Blued, STI prevalence was higher (31.7% vs. 23.9%, P = 0.3), compared with participants recruited through advertisement by the CBO. Most (67.5%) identified as MSM. Survey data confirmed low underlying knowledge of STI transmission and risk factors, especially regarding pre-exposure prophylaxis (PrEP). Conclusion A discreet screening service at a nontraditional site, facilitated through dating application and social media advertisement, was well received by young adult and MSM communities in Wuhan, China. Triple-site STI screening found a significant number of infections among this population and should be routinely offered by public health services. The use of real-time, convenient diagnostic testing presents an opportunity to lower HIV incidence in Wuhan, a city with a large at-risk population. Disclosures All authors: No reported disclosures.

Background: Approximately 1 in 5 Canadians with HIV are unaware of their status. In many provinces and especially rural communities, barriers to HIV testing include lack of access, privacy concerns, and stigma. The availability of HIV point-of-care testing (POCT) is limited across Canada. Pharmacists are well positioned to address barriers by offering rapid HIV POCT and facilitating linkage to care. Methods: We will use a type-2 hybrid implementation-effectiveness design to assess a pilot HIV POCT model in one urban and one rural pharmacy in each of two Canadian provinces over 6 months. In this feasibility trial the research aims include developing and assisting pharmacies in implementing the model, evaluating processes/determinants of program implementation, evaluating the model’s effects on client outcomes, preferences, and testing satisfaction. Using a community-based research approach, the research team will engage community stakeholders in each province including individuals with lived experience to inform the development of the pharmacy-based HIV testing model and support the research team throughout the study. A multipronged promotion campaign will be used to promote the study and facilitate recruitment. The pharmacy-based testing model will include pre/post-test counseling and linkage to care plans in addition to pharmacist-administered HIV POCT. Pharmacists will complete a comprehensive training program prior to implementing the testing model. Client demographics and satisfaction will be assessed by surveys and interviews. Pharmacists will document time required for testing and participate in a post-study focus group to discuss barriers/enablers. Implementation will be assessed qualitatively and quantitatively. The process of developing and implementing the model will be described using qualitative data and a logic model. Acceptability and barriers/enablers will be examined qualitatively based on survey responses. A preliminary costing assessment will consider the client, pharmacy, and government perspectives. Discussion: The results of this pilot will inform modifications to the HIV POCT model to optimize effectiveness and increase scalability. The study has national importance, providing valuable information on improving access to HIV testing. Future applications of this research may expand the role of pharmacists in offering POCT for other sexually transmitted/bloodborne infections as tests become available in Canada.

To determine whether rapid HIV tests in public health centers might encourage voluntary HIV testing, a pilot project was conducted in four selected public health centers in Seoul, 2014. During the period April 10 to November 28 of pilot project, 3,356 rapid tests were performed, and 38 were confirmed as positive. The monthly average numbers of voluntary HIV tests and HIV-positive cases were up to nine-fold and six-fold larger, respectively, than those of the period before application of the rapid HIV test. Among 2,051 examinees that completed questionnaires, 90.3% were satisfied. In conclusion, the use of rapid HIV tests in public health centers promoted voluntary HIV testing and was satisfactory for examinees.

Abstract: Background: Point-of-care (POC) rapid HIV tests have sensitivity during the “window period” comparable only to earliest generation EIAs. To date, it is unclear whether any POC test performs significantly better than others. Objective: Compare abilities of POC tests to detect early infection in real time. Study design: Men who have sex with men (MSM) were recruited into a prospective, cross-sectional study at two HIV testing sites and a research clinic. Procedures compared four POC tests: one performed on oral fluids and three on fingerstick whole blood specimens. Specimens from participants with negative POC results were tested by EIA and pooled nucleic acid amplification testing (NAAT). McNemar's exact tests compared numbers of HIV-infected participants detected. Results: Between February 2010 and May 2013, 104 men tested HIV-positive during 2479 visits. Eighty-two participants had concordant reactive POC results, 3 participants had concordant non-reactive POC tests but reactive EIAs, and 8 participants had acute infection. Of 12 participants with discordant POC results, OraQuick ADVANCE Rapid HIV-1/2 Antibody Test performed on oral fluids identified fewer infections than OraQuick performed on fingerstick (p =.005), Uni-Gold Recombigen HIV test (p =.01), and determine HIV-1/2 Ag/Ab combo (p =.005). Conclusions: These data confirm that oral fluid POC testing detects fewer infections than other methods and is best reserved for circumstances precluding fingerstick or venipuncture. Regardless of specimen type, POC tests failed to identify many HIV-infected MSM in Seattle. In populations with high HIV incidence, the currently approved POC antibody tests are inadequate unless supplemented with p24 antigen tests or NAAT. [Copyright &y& Elsevier]

Purpose: This review examines the literature surrounding acceptability of, and preference for, rapid point-of-care (POC) human immunodeficiency virus (HIV) testing in youth, documents notification rates when youth were offered rapid POC testing, and identifies the sociodemographic factors associated with testing., Methods: The reviewers searched the scholarly literature indexed in MEDLINE, Embase, CINAHL, and PsycInfo using a set of keywords related to youth and rapid POC HIV testing. A total of 14 articles were included in the review., Results: Four themes were identified: (1) Youth will accept rapid POC testing, particularly if offered; (2) youth prefer rapid POC testing to traditional testing; (3) youth receive their rapid POC HIV test results; and (4) older youth and those with HIV risk factors or a concurrent genitourinary diagnosis are more likely to accept rapid POC HIV testing when it is offered., Conclusions: Evidence shows that youth accept and prefer rapid POC HIV tests when offered. The routine use of rapid POC HIV tests in emergency departments and adolescent primary care clinics should be considered because of higher uptake in these environments. Youth receive their rapid POC test results more frequently and sooner than traditional test results. However, further work is needed to develop HIV testing programs that target younger adolescents., (Copyright © 2013. Published by Elsevier Inc.)
