HIV Viral Suppression and Pre-exposure Prophylaxis in HIV and Syphilis Contact Tracing Networks: An Analysis of Disease Surveillance and Prescription Claims Data

Background: HIV and syphilis contact tracing networks offer efficient platforms for HIV treatment and prevention interventions, but intervention coverage within these networks has not been characterized. Setting: HIV and syphilis sexual contact tracing networks among men who have sex with men (MSM) in North Carolina (NC). Methods: Using surveillance data, we identified 2 types of "network events" that occurred between January 2013 and June 2017 among MSM in NC: being diagnosed with early syphilis or being named as a recent sexual contact of a person diagnosed with HIV or early syphilis. We estimated prevalent and incident HIV viral suppression among persons diagnosed with HIV before the network event, and we assessed the effect of contact tracing services on a 6-month cumulative incidence of viral suppression among previously HIV-diagnosed, virally unsuppressed persons. Using linked prescription claims data, we also evaluated prevalent and incident pre-exposure prophylaxis (PrEP) use in an insured subset of HIV-negative network members. Results: Viral suppression prevalence among previously HIV-diagnosed persons was 52.6%. The 6-month cumulative incidence of viral suppression was 35.4% overall and 13.1 (95% confidence interval: 8.8 to 17.4) percentage points higher among persons reached than among those not reached by contact tracing services. Few HIV-negative persons had prevalent (5.4%) or incident (4.1%) PrEP use in the 6 months before or after network events, respectively. Conclusions: Suboptimal viral suppression and PrEP use among MSM in NC in HIV/syphilis contact tracing networks indicate a need for intensified intervention efforts. In particular, expanded services for previously HIV-diagnosed persons could improve viral suppression and reduce HIV transmission within these networks

Pretreatment integrase strand transfer inhibitor resistance in North Carolina from 2010-2016

Objective: We sought to define the prevalence of pretreatment integrase strand transfer inhibitor (INSTI) resistance and assess the transmission networks of those with pretreatment INSTI resistance. Design: A retrospective cohort study of HIV-positive patients with genotypic resistance testing sent to a single referral laboratory in North Carolina between 2010 and 2016. Methods: We linked genotype and public health data for in-care HIV-positive individuals to determine the prevalence of INSTI resistance among treatment-naive (defined as those with a first genotype ≤3 months after diagnosis) and treatment-experienced (defined as those with a first genotype >3 months after diagnosis) patients. We performed molecular and phylogenetic analyses to assess whether pretreatment INSTI resistance mutations represented clustered HIV transmission. Results: Of 8825 individuals who contributed sequences for protease, reverse transcriptase, or INSTI genotypic resistance testing during the study period, 2784 (31%) contributed at least one sequence for INSTI resistance testing. Of these, 840 were treatment-naive individuals and 20 [2.4%, 95% confidence interval (CI): 1.5, 3.6%] had INSTI mutations; only two (0.2%, 95% CI: 0.02, 0.9%) had major mutations. Of 1944 treatment-experienced individuals, 9.6% (95% CI: 8.3, 11.0%) had any INSTI mutation and 7.0% (95% CI: 5.9, 8.3%) had major mutations; the prevalence of INSTI mutations among treatment-experienced patients decreased overtime (P<0.001). In total 12 of 20 individuals with pretreatment INSTI mutations were part of 10 molecular transmission clusters; only one cluster shared identical minor mutations. Conclusion: The prevalence of major pretreatment INSTI resistance is very low. Pretreatment INSTI mutations do not appear to represent clustered HIV transmission

Improvements in Timeliness Resulting from Implementation of Electronic Laboratory Reporting and an Electronic Disease Surveillance System

Electronic laboratory reporting (ELR) reduces the time between communicable disease diagnosis and case reporting to local health departments (LHDs). However, it also imposes burdens on public health agencies, such as increases in the number of unique and duplicate case reports. We assessed how ELR affects the timeliness and accuracy of case report processing within public health agencies

Provider Perspectives on Rapid Treatment Initiation Among People Newly Diagnosed With HIV: A New Message of “Urgency”?

Background Early initiation of antiretroviral therapy improves human immunodeficiency virus (HIV) outcomes. However, achieving earlier treatment initiation is challenging for many reasons including provider awareness and clinic barriers; this study sought to understand perceptions of an early initiation program. Methods We interviewed 10 providers from 3 HIV clinics in North Carolina (October-November 2020). We asked providers about overall perceptions of early initiation and the pilot program. We developed narrative summaries to understand individual contexts and conducted thematic analysis using NVivo. Results Providers believed earlier initiation would signal an “extra sense of urgency” about the importance of antiretroviral therapy—a message not currently reflected in standard of care. Safety was a consistent concern. Cited implementation barriers included transportation assistance, medication sustainability, and guidance to address increased staff time and appointment availability. Conclusion Our qualitative findings highlight the need for training on the safety of early initiation and addressing staffing needs to accommodate quicker appointments.Plain Language Summary Doctor and clinic staff perspectives on a program to immediately start HIV treatment among patients newly diagnosed with HIV Treating human immunodeficiency virus (HIV) is easier than ever. Starting newly diagnosed persons on HIV medication as soon as possible is a now recommended goal. However, starting patients right away can be challenging. This study interviewed doctors and clinic staff to better understand their perspectives prior to implementing a program that would provide newly diagnosed patients with HIV treatment immediately. Results showed that some doctors are worried patients will not return after receiving their medications. Providers want support for linking patients to the clinic and ensuring they will be able to receive their next dose of medication when they come in. Other providers saw the benefits of reducing HIV stigma if the program can more quickly start patients on treatment. Some providers explained that when you go to the doctor and are sick you receive medications immediately, yet for newly diagnosed patients living with HIV, patients can be told to come back a month later to start treatment. Some providers believe shifting this messaging may also help patients take their medications better. Most providers saw the need for clinics to have more same-day appointment availability to meet the needs of the new program. Overall, providers were excited about the opportunity to improve the HIV care by offering HIV medications to newly diagnosed patients immediately

HIV-1 Transmission linkages among persons with incident infection to inform public health surveillance

Background: We evaluated features of HIV transmission networks involving persons diagnosed during incident HIV infection (IHI) to assess network-based opportunities to curtail onward transmission. Methods: Transmission networks were constructed using partial pol sequences reported to North Carolina surveillance among persons with recent (2014–2018) and past (90 days prior to an IHI were further characterized. We assessed named partner outcomes among IHI index persons using contact tracing data. Findings: Of 4,405 HIV diagnoses 2014–2018 with sequences, there were 323 (7%) IHI index persons; most were male (88%), Black (65%), young (68% <30 years), and reported sex with men (MSM) risk (79%). Index persons were more likely to be cluster members compared to non-index persons diagnosed during the same period (72% vs. 49%). In total, 162 clusters were identified involving 233 IHI, 577 recent diagnoses, and 163 past diagnoses. Most IHI cases (53%) had viral linkages to ≥1 previously diagnosed person without evidence of HIV viral suppression in the year prior to the diagnosis of the IHI index. In contact tracing, only 53% IHI cases named an HIV-positive contact, resulting in 0.5 previously diagnosed persons detected per IHI investigated. When combined with viral analyses, the detection rate of viremic previously diagnosed persons increased to 1.3. Interpretation: Integrating public health with molecular epidemiology, revealed that more than half of IHI have viral links to persons with previously diagnosed unsuppressed HIV infection which was largely unrecognized by traditional contact tracing. Enhanced partner services to support engagement and retention in HIV care and improved case finding supported by rapid phylogenetic analysis are tools to substantially reduce onward HIV transmission

COMPARE Forum: The idea of North-South and South-South collaboration

The idea of having a Compare Forum focusing on the above title was first discussed with one of the Editors of Compare during a PhD defence in Oslo in 2011. The PhD dissertation itself was linked to a larger project in which researchers from the North (Norway) and the South (South Africa) had been collaborating in educational research for over 10 years. Despite the fact that North-South collaboration is not a new issue on the agenda (King 1985) it is still a timely topic to explore, particularly given the recent growth and moves towards North-South-South collaboration or even South-South Cooperation in Education and Development (Chisholm and Steiner-Khamsi 2009). Thus, any discussion of research collaboration, whether North-South or South-South, is seen as an ideal topic for comparative education, particularly when exploring why there should be collaboration at all and if so what are some of the challenges. While it may be argued that the difference between North-South and South-South collaboration may simply be a question of geography, King (1985) reminds us that collaboration is not necessarily between equals and that collaboration at times ‘appears to be a process initiated in the North, and in which the South participates, as a counterpart’ (184). Ultimately, the differences go beyond simple geographic location to issues of funding and power, something that each of the contributions will touch upon in their own way. While cooperation may mean working with someone, it does suggest that one partner provides information or resources to the other, while collaboration suggests a more equal partnership in which researchers work alongside each other. For the majority of our contributors, we use collaboration as opposed to cooperation, although the literature is not always so clear on this distinction.Web of Scienc

Beyond outputs: pathways to symmetrical evaluations of university sustainable development partnerships

As the United Nations Decade of Education for Sustainable Development (2005–2014) draws to a close, it is timely to review ways in which the sustainable development initiatives of higher education institutions have been, and can be, evaluated. In their efforts to document and assess collaborative sustainable development program outcomes and impacts, universities in the North and South are challenged by similar conundrums that confront development agencies. This article explores pathways to symmetrical evaluations of transnationally partnered research, curricula, and public-outreach initiatives specifically devoted to sustainable development. Drawing on extensive literature and informed by international development experience, the authors present a novel framework for evaluating transnational higher education partnerships devoted to sustainable development that addresses design, management, capacity building, and institutional outreach. The framework is applied by assessing several full-term African higher education evaluation case studies with a view toward identifying key limitations and suggesting useful future symmetrical evaluation pathways. University participants in transnational sustainable development initiatives, and their supporting donors, would be well-served by utilizing an inclusive evaluation framework that is infused with principles of symmetry

Near Real-Time Identification of Recent Human Immunodeficiency Virus Transmissions, Transmitted Drug Resistance Mutations, and Transmission Networks by Multiplexed Primer ID–Next-Generation Sequencing in North Carolina

Background: The identification of recent human immunodeficiency virus (HIV) 1 infections among people with new HIV diagnoses is important to both tailoring and assessing the impact of HIV-1 prevention strategies. Methods: We developed a multiplexed Primer ID-next-generation sequencing approach to identify recent infections by measuring the intrahost viral diversity over multiple regions of the HIV-1 genome, in addition to detecting drug resistance mutations (DRMs) and phylogenetically linked clusters. We summarize the field implementation of this all-in-one platform among persons with newly diagnosed HIV-1 by the North Carolina State Laboratory of Public Health in 2018. Results: Overall, recent infection was identified in 94 (35%) of 268 patients with new HIV diagnoses. People <30 years old, and people who inject drugs were more likely to have diagnoses of recent infection. The reverse-transcriptase region K103N was the most commonly detected DRM (prevalence, approximately 15%). We found a total of 28 clusters, and persons with recent infection were more likely to be cluster members than were those with chronic infections (P =. 03). Conclusions: We demonstrate the rapid identification of recent infection and pretreatment DRMs coupled with cluster analysis that will allow prioritization of linkage to care, treatment, and prevention interventions to those at highest risk of onward transmission
