Item Open Access A cross-sectional analysis of HIV and hepatitis C clinical trials 2007 to 2010: the relationship between industry sponsorship and randomized study design.(Trials, 2014-01) Goswami, Neela D; Tsalik, Ephraim L; Naggie, Susanna; Miller, William C; Horton, John R; Pfeiffer, Christopher D; Hicks, Charles BBackground
The proportion of clinical research sponsored by industry will likely continue to expand as federal funds for academic research decreases, particularly in the fields of HIV/AIDS and hepatitis C (HCV). While HIV and HCV continue to burden the US population, insufficient data exists as to how industry sponsorship affects clinical trials involving these infectious diseases. Debate exists about whether pharmaceutical companies undertake more market-driven research practices to promote therapeutics, or instead conduct more rigorous trials than their non-industry counterparts because of increased resources and scrutiny. The ClinicalTrials.gov registry, which allows investigators to fulfill a federal mandate for public trial registration, provides an opportunity for critical evaluation of study designs for industry-sponsored trials, independent of publication status. As part of a large public policy effort, the Clinical Trials Transformation Initiative (CTTI) recently transformed the ClinicalTrials.gov registry into a searchable dataset to facilitate research on clinical trials themselves.Methods
We conducted a cross-sectional analysis of 477 HIV and HCV drug treatment trials, registered with ClinicalTrials.gov from 1 October 2007 to 27 September 2010, to study the relationship of study sponsorship with randomized study design. The likelihood of using randomization given industry (versus non-industry) sponsorship was reported with prevalence ratios (PR). PRs were estimated using crude and stratified tabular analysis and Poisson regression adjusting for presence of a data monitoring committee, enrollment size, study phase, number of study sites, inclusion of foreign study sites, exclusion of persons older than age 65, and disease condition.Results
The crude PR was 1.17 (95% CI 0.94, 1.45). Adjusted Poisson models produced a PR of 1.13 (95% CI 0.82, 1.56). There was a trend toward mild effect measure modification by study phase, but this was not statistically significant. In stratified tabular analysis the adjusted PR was 1.14 (95% CI 0.78, 1.68) among phase 2/3 trials and 1.06 (95% CI 0.50, 2.22) among phase 4 trials.Conclusions
No significant relationship was found between industry sponsorship and use of randomization in trial design in this cross-sectional study. Prospective studies evaluating other aspects of trial design may shed further light on the relationship between industry sponsorship and appropriate trial methodology.Item Open Access A minimal monitoring approach for the treatment of hepatitis C virus infection (ACTG A5360 [MINMON]): a phase 4, open-label, single-arm trial.(The lancet. Gastroenterology & hepatology, 2022-04) Solomon, Sunil S; Wagner-Cardoso, Sandra; Smeaton, Laura; Sowah, Leonard A; Wimbish, Chanelle; Robbins, Gregory; Brates, Irena; Scello, Christine; Son, Annie; Avihingsanon, Anchalee; Linas, Benjamin; Anthony, Donald; Nunes, Estevão Portela; Kliemann, Dimas A; Supparatpinyo, Khuanchai; Kityo, Cissy; Tebas, Pablo; Bennet, Jaclyn Ann; Santana-Bagur, Jorge; Benson, Constance A; Van Schalkwyk, Marije; Cheinquer, Nelson; Naggie, Susanna; Wyles, David; Sulkowski, MarkBackground
Despite widespread availability of direct-acting antivirals including generic formulations, limited progress has been made in the global adoption of hepatitis C virus (HCV) treatment. Barriers to treatment scale-up include availability and access to diagnostic and monitoring tests, health-care infrastructure, and requirement for frequent visits during treatment.Methods
ACTG A5360 was a phase 4, open-label, single-arm trial across 38 sites in Brazil, South Africa, Thailand, Uganda, and the USA. Key inclusion criteria were age of 18 years or older, evidence of active HCV infection (HCV RNA >1000 IU/mL) and HCV treatment-naive; patients with compensated cirrhosis and HIV/HCV co-infection were included but their enrolment was capped. All participants received a fixed dose combination of oral sofosbuvir (400 mg) and velpatasvir (100 mg) once daily for 12 weeks. The minimal monitoring (MINMON) approach consisted of four components: (1) there was no pre-treatment genotyping; (2) the entire treatment course (84 tablets) was dispensed at entry; (3) there were no scheduled visits or laboratory monitoring; and (4) there were two points of remote contact, at week 4 for adherence and week 22, to schedule outcome assessment at week 24 (-2 weeks to +4 weeks). Participants who missed the week 24 window could return for a visit to assess treatment response any time before week 72. Unplanned visits for any reason were permissible before the week 24 visit. The primary efficacy outcome was sustained virological response (SVR), defined as HCV RNA less than the lower limit of quantification measured at least 22 weeks post-treatment initiation; the primary safety outcome was serious adverse events. The primary efficacy analysis included all participants who initiated treatment, using a missing=failure approach. The primary safety analysis included all participants who initiated treatment and had at least one post-treatment assessment. This trial is registered at ClinicalTrials.gov, NCT03512210.Findings
Between Oct 22, 2018, and July 19, 2019, 400 participants were enrolled across all 38 sites; 399 initiated treatment. At the SVR assessment visit, 355 (89%) of 397 participants reported taking 100% of the trial medication during the 12-week treatment period; two patients did not have any follow-up visits after the entry visit and were excluded from the safety analyses. Overall, 379 of the 399 who initiated treatment had an SVR (95·0%, 95% CI 92·4-96·7). 14 (4%) of 397 participants reported serious adverse events between treatment initiation and week 28; none were treatment related or led to treatment discontinuation or death. 15 (4%) of 399 participants had unplanned visits; none were related to treatment.Interpretation
In this diverse global population of people with HCV, the MINMON approach with sofosbuvir-velpatasvir treatment was safe and achieved SVR comparable to standard monitoring observed in real-world data. Coupled with innovative case finding strategies, this strategy could be crucial to the global HCV elimination agenda.Funding

Primary pulmonary coccidioidomycosis (PPC) is a leading cause of community-acquired pneumonia (CAP) in this region, although its diagnosis is often delayed, leading to lag in antifungal treatment and subsequent morbidity. The impact of early empiric antifungal therapy as part of treatment for CAP in endemic areas on clinical outcomes is unknown. Methods: Phase IV randomized, double-blind, placebo-controlled trial in individuals aged 18 years or older with CAP who met all eligibility criteria in Coccidioides endemic regions in the US. Eligible participants with CAP were randomized to receive either fluconazole (400 mg daily) or matching placebo for 42 days and were subsequently monitored for clinical resolution of their illness. Objectives: The primary objective was to assess the clinical response of early empiric antifungal therapy with fluconazole through Day 22 in subjects with PPC who were adherent to the study intervention. Secondary objectives included: assessments of the impact of early empiric antifungal therapy with fluconazole through Day 22 and 43 in subjects with PPC regardless of adherence, comparisons of the clinical response and its individual components over time by treatment group in subjects with PPC, assessments of days lost from work or school, hospitalization, and all-cause mortality. Discussion: This trial was halted early due to slow enrollment (72 participants in one year, 33 received fluconazole and 39 received placebo). Of those enrolled, eight (11%) met the study definition of PPC. The study design and challenges are discussed.Item Open Access A telehealth-delivered intervention to extend the veteran HIV treatment cascade for cardiovascular disease prevention: V-EXTRA-CVD study protocol for a randomized controlled trial.(HIV research & clinical practice, 2023-12) Musoke, Lewis; Bosworth, Hayden B; Dickson, Christina; Gentry, Pamela; Strawbridge, Elizabeth; Subramaniam, Soumya; Gierisch, Jennifer; Smith, Valerie; Woolson, Sandra; Pura, John; Amutuhaire, Willington; Naggie, Susanna; Schexnayder, Julie; Hall, Karen; Longenecker, Chris T; Harris, Nadine M; Rogers, Chantrice; Van Epps, Puja; for V-EXTRA-CVD GroupBackground: Veterans living with HIV have up to twice the risk of atherosclerotic cardiovascular disease (ASCVD) compared to those without HIV.Objective: Our study seeks to test a non-physician led virtual self-management implementation strategy to reduce ASCVD risk among people living with HIV (PWH). We aim to conduct a randomized control trial among PWH (n = 300) with a diagnosis of hypertension (HTN) who are enrolled in Veterans Health Administration (VHA) clinics, on suppressive antiretroviral therapy (ART), randomized 1:1 to intervention vs. education control for a 12-month duration.Methods: Using human centered design approach, we have adapted a previous 5-component telehealth focused, non-physician led intervention to a Veteran population. The education control arm receives enhanced education in addition to usual care. The primary outcome is 6 mmHg reduction in systolic BP over 12-month in the intervention arm compared to the control arm. The secondary outcome is a 12-month difference in non-HDL cholesterol. While each component of our intervention has an evidence base, they have not been tested together in an HIV context.Conclusion: The proposed multicomponent intervention has the potential to improve cardiovascular outcomes in PWH using novel virtual care methods in a patient centered care approach.Item Open Access An integrated alcohol abuse and medical treatment model for patients with hepatitis C.(Dig Dis Sci, 2012-04) Proeschold-Bell, Rae Jean; Patkar, Ashwin A; Naggie, Susanna; Coward, Lesleyjill; Mannelli, Paolo; Yao, Jia; Bixby, Patricia; Muir, Andrew JBACKGROUND: Patients with chronic hepatitis C virus (HCV) infection have high rates of alcohol consumption, which is associated with progression of fibrosis and lower response rates to HCV treatment. AIMS: This prospective cohort study examined the feasibility of a 24-week integrated alcohol and medical treatment to HCV-infected patients. METHODS: Patients were recruited from a hepatology clinic if they had an Alcohol Use Disorders Identification Test score >4 for women and >8 for men, suggesting hazardous alcohol consumption. The integrated model included patients receiving medical care and alcohol treatment within the same clinic. Alcohol treatment consisted of 6 months of group and individual therapy from an addictions specialist and consultation from a study team psychiatrist as needed. RESULTS: Sixty patients were initially enrolled, and 53 patients participated in treatment. The primary endpoint was the Addiction Severity Index (ASI) alcohol composite scores, which significantly decreased by 0.105 (41.7% reduction) between 0 and 3 months (P < 0.01) and by 0.128 (50.6% reduction) between 0 and 6 months (P < 0.01) after adjusting for covariates. Alcohol abstinence was reported by 40% of patients at 3 months and 44% at 6 months. Patients who did not become alcohol abstinent had reductions in their ASI alcohol composite scores from 0.298 at baseline to 0.219 (26.8% reduction) at 6 months (P = 0.08). CONCLUSION: This study demonstrated that an integrated model of alcohol treatment and medical care could be successfully implemented in a hepatology clinic with significant favorable impact on alcohol use and abstinence among patients with chronic HCV.Item Open Access Antiretroviral Effects on Host Lipoproteins Are Associated With Changes in Hepatitis C Virus (HCV) RNA Levels in Human Immunodeficiency Virus/HCV Coinfected Individuals.(Open forum infectious diseases, 2015-04) Naggie, Susanna; Patel, Keyur; Yang, Lan-Yan; Chow, Shein-Chung; Johnson, Victoria; Guyton, John R; Muir, Andrew J; Sulkowski, Mark; Hicks, CharlesWe evaluated the impact of antiretroviral-induced dyslipidemia on hepatitis C virus (HCV) biogenesis in human immunodeficiency virus (HIV)/HCV coinfected patients. This study used serum samples from antiretroviral-naive HIV/HCV patients initiating their first regimen as part of AIDS Clinical Trials Group study protocols (A5142, A5202). Initiation of antiretrovirals increased most lipoproteins and apolipoproteins. In the multivariable model, changes in apolipoproteins were associated with changes in log10 HCV RNA from baseline to week-24 of therapy. Off-target lipogenic changes need to be considered in the context of liver and other metabolic disease in HIV/HCV patients.Item Open Access Author Correction: Mortality outcomes with hydroxychloroquine and chloroquine in COVID-19 from an international collaborative meta-analysis of randomized trials.(Nature communications, 2021-05-14) Axfors, Cathrine; Schmitt, Andreas M; Janiaud, Perrine; Van't Hooft, Janneke; Abd-Elsalam, Sherief; Abdo, Ehab F; Abella, Benjamin S; Akram, Javed; Amaravadi, Ravi K; Angus, Derek C; Arabi, Yaseen M; Azhar, Shehnoor; Baden, Lindsey R; Baker, Arthur W; Belkhir, Leila; Benfield, Thomas; Berrevoets, Marvin AH; Chen, Cheng-Pin; Chen, Tsung-Chia; Cheng, Shu-Hsing; Cheng, Chien-Yu; Chung, Wei-Sheng; Cohen, Yehuda Z; Cowan, Lisa N; Dalgard, Olav; de Almeida E Val, Fernando F; de Lacerda, Marcus VG; de Melo, Gisely C; Derde, Lennie; Dubee, Vincent; Elfakir, Anissa; Gordon, Anthony C; Hernandez-Cardenas, Carmen M; Hills, Thomas; Hoepelman, Andy IM; Huang, Yi-Wen; Igau, Bruno; Jin, Ronghua; Jurado-Camacho, Felipe; Khan, Khalid S; Kremsner, Peter G; Kreuels, Benno; Kuo, Cheng-Yu; Le, Thuy; Lin, Yi-Chun; Lin, Wu-Pu; Lin, Tse-Hung; Lyngbakken, Magnus Nakrem; McArthur, Colin; McVerry, Bryan J; Meza-Meneses, Patricia; Monteiro, Wuelton M; Morpeth, Susan C; Mourad, Ahmad; Mulligan, Mark J; Murthy, Srinivas; Naggie, Susanna; Narayanasamy, Shanti; Nichol, Alistair; Novack, Lewis A; O'Brien, Sean M; Okeke, Nwora Lance; Perez, Léna; Perez-Padilla, Rogelio; Perrin, Laurent; Remigio-Luna, Arantxa; Rivera-Martinez, Norma E; Rockhold, Frank W; Rodriguez-Llamazares, Sebastian; Rolfe, Robert; Rosa, Rossana; Røsjø, Helge; Sampaio, Vanderson S; Seto, Todd B; Shahzad, Muhammad; Soliman, Shaimaa; Stout, Jason E; Thirion-Romero, Ireri; Troxel, Andrea B; Tseng, Ting-Yu; Turner, Nicholas A; Ulrich, Robert J; Walsh, Stephen R; Webb, Steve A; Weehuizen, Jesper M; Velinova, Maria; Wong, Hon-Lai; Wrenn, Rebekah; Zampieri, Fernando G; Zhong, Wu; Moher, David; Goodman, Steven N; Ioannidis, John PA; Hemkens, Lars GThe original version of this Article contained an error in the spelling of the author Muhammad Shahzad, which was incorrectly given as Muhammad Shehzad.

The NCT04323527 registration includes the trials CloroCOVID19I and CloroCOVID19III. CloroCOVID19I was not included in the meta-analysis. In addition, the original version of the Methods section inadvertently omitted details of which formulations of hydroxychloroquine or chloroquine the reported dosages refer to. The following information has been included in the legend for Table 1 and in the corrected methods section: “In all trials that used hydroxychloroquine, dosages refer to hydroxychloroquine sulfate. In trials that used chloroquine, the dosages for ARCHAIC, ChiCTR2000030054 and ChiCTR2000031204 refer to chloroquine phosphate, while those for CloroCOVID19II and CloroCOVID19III refer to chloroquine base. The American Journal of Tropical Medicine and Hygiene has issued a retraction note (1) for one of the trials (2) that had been included in the calculations of our meta-analysis. Exclusion of the data from this trial changes neither the results nor inferences of the meta-analysis. For hydroxychloroquine, the original odds ratio for mortality was 1.11 (95% CI: 1.02–1.20; I2 = 0%; 26 trials; 10,012 patients) and excluding the retracted trial the odds ratio for mortality would remain 1.11 (95% CI: 1.02–1.20, I2 = 0%; 25 trials; 9818 patients).

The impact of clinician specialty on cardiovascular disease risk factor outcomes among persons with HIV (PWH) is unclear.Methods
PWH receiving care at 3 Southeastern US academic HIV clinics between January 2014 and December 2016 were retrospectively stratified into 5 groups based on the specialty of the clinician managing their hypertension or hyperlipidemia. Patients were followed until first atherosclerotic cardiovascular disease event, death, or end of study. Outcomes of interest were meeting 8th Joint National Commission (JNC-8) blood pressure (BP) goals and National Lipid Association (NLA) non-high-density lipoprotein (HDL) goals for hypertension and hyperlipidemia, respectively. Point estimates for associated risk factors were generated using modified Poisson regression with robust error variance.Results
Of 1667 PWH in the analysis, 965 had hypertension, 205 had hyperlipidemia, and 497 had both diagnoses. At study start, the median patient age was 52 years, 66% were Black, and 65% identified as male. Among persons with hypertension, 24% were managed by an infectious diseases (ID) clinician alone, and 5% were co-managed by an ID clinician and a primary care clinician (PCC). Persons managed by an ID clinician were less likely to meet JNC-8 hypertension targets at the end of observation than the rest of the cohort (relative risk [RR], 0.84; 95% CI, 0.75-0.95), but when mean study blood pressure was considered, there was no difference between persons managed by ID and the rest of the cohort (RR, 0.96; 95% CI, 0.88-1.05). There was no significant association between the ID clinician managing hyperlipidemia and meeting NLA non-HDL goals (RR, 0.89; 95% CI, 0.68-1.15).Conclusions
Clinician specialty may play a role in suboptimal hypertension outcomes in persons with HIV.Item Open Access Community-based HCV screening: knowledge and attitudes in a high risk urban population.(BMC Infect Dis, 2014-02-10) Norton, Brianna L; Voils, Corrine I; Timberlake, Sarah H; Hecker, Emily J; Goswami, Neela D; Huffman, Kim M; Landgraf, Anneka; Naggie, Susanna; Stout, Jason EBACKGROUND: In an attempt to curtail the rising morbidity and mortality from undiagnosed HCV (hepatitis C virus) in the United States, screening guidelines have been expanded to high-risk individuals and persons born 1945-1965. Community-based screening may be one strategy in which to reach such persons; however, the acceptance of HCV testing, when many high-risk individuals may not have access to HCV specific medications, remains unknown. METHODS: We set out to assess attitudes about HCV screening and knowledge about HCV disease at several community-based testing sites that serve high-risk populations. This assessment was paired with a brief HCV educational intervention, followed by post-education evaluation. RESULTS: Participants (n = 140) were surveyed at five sites; two homeless shelters, two drug rehabilitation centers, and a women's "drop-in" center. Personal acceptance of HCV testing was almost unanimous, and 90% of participants reported that they would still want to be tested even if they were unable to receive HCV treatment. Baseline hepatitis C knowledge was poor; however, the brief educational intervention significantly improved knowledge and increased acceptability of testing when medical access issues were explicitly stated. CONCLUSIONS: Despite inconsistencies in access to care and treatment, high-risk communities want to know their HCV status. Though baseline HCV knowledge was poor in this population, a brief on-site educational intervention improved both knowledge and acceptability of HCV testing and care. These data support the establishment of programs that utilize community-based screening, and also provide initial evidence for acceptance of the implementation of the recently expanded screening guidelines among marginalized communities.Item Open Access Correlation Between Tenofovir Drug Levels and the Renal Biomarkers RBP-4 and ß2M in the ION-4 Study Cohort.(Open forum infectious diseases, 2019-01) Chan, Austin; Park, Lawrence; Collins, Lauren F; Cooper, Curtis; Saag, Michael; Dieterich, Douglas; Sulkowski, Mark; Naggie, SusannaBackground
Concomitant dosing of ledipasvir (LDV) and tenofovir disoproxil fumarate (TDF) results in an increased tenofovir (TFV) area under the curve (AUC). The aim of this study was to examine whether there was a correlation between the renal biomarkers retinol binding protein-4 (RBP-4) and β2 microglobulin (β2M) and tenofovir AUC.Methods
The ION-4 trial enrolled HIV/hepatitis C virus-coinfected patients on nonpharmacologically boosted antiretroviral regimens with TDF-containing backbones. We assessed for a correlation between tenofovir AUC and urinary biomarkers and also for changes in serologic biomarkers with respect to clinically relevant changes in renal function (creatinine clearance decrease >25%, change in creatinine >0.2 mg/dL, change in proteinuria from negative/trace to ≥1+).Results
Three hundred thirty-five patients were enrolled in the ION-4 study; their demographic characteristics have been previously described. Both RBP-4 and β2M exhibited positive correlations with tenofovir AUC. Baseline and study levels of RBP-4 and β2M were higher for patients with increases in urine proteinuria and an absolute creatinine increase.Conclusions
TFV exposure is associated with increased proximal tubule urine biomarkers in participants on ledipasvir/sofosbuvir and nonpharmacologically boosted TDF-based antiretroviral regimens. Baseline proximal tubule biomarkers may predict nephrotoxicity risk if events are prevalent. Further studies assessing the predictive role of these urine biomarkers may help guide medical decision-making and risk/benefit assessments in patients with risk factors for renal dysfunction.Item Open Access COVID-19 Trials: Who Participates and Who Benefits?(Southern medical journal, 2022-04) Narayanasamy, Shanti; Mourad, Ahmad; Turner, Nicholas A; Le, Thuy; Rolfe, Robert J; Okeke, Nwora Lance; O'Brien, Sean M; Baker, Arthur W; Wrenn, Rebekah; Rosa, Rossana; Rockhold, Frank W; Naggie, Susanna; Stout, Jason EObjectives
The coronavirus disease 2019 (COVID-19) pandemic has disproportionately afflicted vulnerable populations. Older adults, particularly residents of nursing facilities, represent a small percentage of the population but account for 40% of mortality from COVID-19 in the United States. Racial and ethnic minority individuals, particularly Black, Hispanic, and Indigenous Americans have experienced higher rates of infection and death than the White population. Although there has been an unprecedented explosion of clinical trials to examine potential therapies, participation by members of these vulnerable communities is crucial to obtaining data generalizable to those communities.Methods
We undertook an open-label, factorial randomized clinical trial examining hydroxychloroquine and/or azithromycin for hospitalized patients.Results
Of 53 screened patients, 11 (21%) were enrolled. Ten percent (3/31) of Black patients were enrolled, 33% (7/21) of White patients, and 50% (6/12) of Hispanic patients. Forty-seven percent (25/53) of patients declined participation despite eligibility; 58%(18/31) of Black patients declined participation. Forty percent (21/53) of screened patients were from a nursing facility and 10% (2/21) were enrolled. Enrolled patients had fewer comorbidities than nonenrolled patients: median modified Charlson comorbidity score 2.0 (interquartile range 0-2.5), versus 4.0 (interquartile range 2-6) for nonenrolled patients (P = 0.006). The limitations of the study were the low participation rate and the multiple treatment trials concurrently recruiting at our institution.Conclusions
The high rate of nonparticipation in our trial of nursing facility residents and Black people emphasizes the concern that clinical trials for therapeutics may not target key populations with high mortality rates.Item Open Access COVID-19-Lessons Learned and Questions Remaining.(Clinical infectious diseases : an official publication of the Infectious Diseases Society of America, 2021-06) Fang, Ferric C; Benson, Constance A; Del Rio, Carlos; Edwards, Kathryn M; Fowler, Vance G; Fredricks, David N; Limaye, Ajit P; Murray, Barbara E; Naggie, Susanna; Pappas, Peter G; Patel, Robin; Paterson, David L; Pegues, David A; Petri, William A; Schooley, Robert TIn this article, the editors of Clinical Infectious Diseases review some of the most important lessons they have learned about the epidemiology, clinical features, diagnosis, treatment and prevention of SARS-CoV-2 infection and identify essential questions about COVID-19 that remain to be answered.Item Open Access Cumulative Human Immunodeficiency Virus (HIV)-1 Viremia Is Associated With Increased Risk of Multimorbidity Among US Women With HIV, 1997-2019.(Open forum infectious diseases, 2023-02) Morton, Zoey P; Christina Mehta, C; Wang, Tingyu; Palella, Frank J; Naggie, Susanna; Golub, Elizabeth T; Anastos, Kathryn; French, Audrey L; Kassaye, Seble; Taylor, Tonya N; Fischl, Margaret A; Adimora, Adaora A; Kempf, Mirjam-Colette; Tien, Phyllis C; Ofotokun, Ighovwerha; Sheth, Anandi N; Collins, Lauren FBackground
To evaluate the effect of cumulative human immunodeficiency virus (HIV)-1 viremia on aging-related multimorbidity among women with HIV (WWH), we analyzed data collected prospectively among women who achieved viral suppression after antiretroviral therapy (ART) initiation (1997-2019).Methods
We included WWH with ≥2 plasma HIV-1 viral loads (VL) <200 copies/mL within a 2-year period (baseline) following self-reported ART use. Primary outcome was multimorbidity (≥2 nonacquired immune deficiency syndrome comorbidities [NACM] of 5 total assessed). The trapezoidal rule calculated viremia copy-years (VCY) as area-under-the-VL-curve. Cox proportional hazard models estimated the association of time-updated cumulative VCY with incident multimorbidity and with incidence of each NACM, adjusting for important covariates (eg, age, CD4 count, etc).Results
Eight hundred six WWH contributed 6368 women-years, with median 12 (Q1-Q3, 7-23) VL per participant. At baseline, median age was 39 years, 56% were Black, and median CD4 was 534 cells/mm3. Median time-updated cumulative VCY was 5.4 (Q1-Q3, 4.7-6.9) log10 copy-years/mL. Of 211 (26%) WWH who developed multimorbidity, 162 (77%) had incident hypertension, 133 (63%) had dyslipidemia, 60 (28%) had diabetes, 52 (25%) had cardiovascular disease, and 32 (15%) had kidney disease. Compared with WWH who had time-updated cumulative VCY <5 log10, the adjusted hazard ratio of multimorbidity was 1.99 (95% confidence interval [CI], 1.29-3.08) and 3.78 (95% CI, 2.17-6.58) for those with VCY 5-6.9 and ≥7 log10 copy-years/mL, respectively (P < .0001). Higher time-updated cumulative VCY increased the risk of each NACM.Conclusions
Among ART-treated WWH, greater cumulative viremia increased the risk of multimorbidity and of developing each NACM, and hence this may be a prognostically useful biomarker for NACM risk assessment in this population.Item Open Access Design of the Healthcare Worker Exposure Response and Outcomes (HERO) research platform.(Contemporary clinical trials, 2021-10) Friedland, Anne; Hernandez, Adrian F; Anstrom, Kevin J; Chen-Lim, Mei Lin; Cohen, Lauren W; Currier, Judith S; Forrest, Christopher B; Fraser, Ryan; Fraulo, Elizabeth; George, Anoop; Handberg, Eileen; Jackman, Jennifer; Koellhoffer, Jayne; Lawrence, Daryl; Leverty, Renee; McAdams, Patty; McCourt, Brian; Mickley, Brenda; Naqvi, Syed Hasan; O'Brien, Emily C; Olson, Rachel; Prater, Clyde; Rothman, Russell L; Shenkman, Elizabeth; Shostak, Jack; Turner, Kisha Batey; Webb, Laura; Woods, Chris; Naggie, Susanna; HERO Research ProgramBackground
The SARS CoV-2 virus has caused one of the deadliest pandemics in recent history, resulting in over 170 million deaths and global economic disruption. There remains an urgent need for clinical trials to test therapies for treatment and prevention.Design
An online research platform was created to support a registry community of healthcare workers (HCWs) to understand their experiences and conduct clinical studies to address their concerns. The first study, HERO-HCQ, was a double-blind, multicenter, randomized, pragmatic trial to evaluate the superiority of hydroxychloroquine (HCQ) vs placebo for pre-exposure prophylaxis (PrEP) of COVID-19 clinical infection in HCWs. Secondary objectives were to assess the efficacy of HCQ in preventing viral shedding of COVID-19 among HCWs and to assess the safety and tolerability of HCQ.Methods
HCWs joined the Registry and were pre-screened for trial interest and eligibility. Trial participants were randomized 1:1 to receive HCQ or placebo. On-site baseline assessment included a COVID-19 nasopharyngeal PCR and blood serology test. Weekly follow-up was done via an online portal and included screening for symptoms of COVID-19, self-reported testing, adverse events, and quality of life assessments. The on-site visit was repeated at Day 30.Discussion
The HERO research platform offers an approach to rapidly engage, screen, invite and enroll into clinical studies using a novel participant-facing online portal interface and remote data collection, enabling limited onsite procedures for conduct of a pragmatic clinical trial. This platform may be an example for future clinical trials of common conditions to enable more rapid evidence generation.Item Open Access Developing Treatment Guidelines During a Pandemic Health Crisis: Lessons Learned From COVID-19.(Annals of internal medicine, 2021-08) Kuriakose, Safia; Singh, Kanal; Pau, Alice K; Daar, Eric; Gandhi, Rajesh; Tebas, Pablo; Evans, Laura; Gulick, Roy M; Lane, H Clifford; Masur, Henry; NIH COVID-19 Treatment Guidelines Panel; Aberg, Judith A; Adimora, Adaora A; Baker, Jason; Kreuziger, Lisa Baumann; Bedimo, Roger; Belperio, Pamela S; Cantrill, Stephen V; Coopersmith, Craig M; Davis, Susan L; Dzierba, Amy L; Gallagher, John J; Glidden, David V; Grund, Birgit; Hardy, Erica J; Hinkson, Carl; Hughes, Brenna L; Johnson, Steven; Keller, Marla J; Kim, Arthur Y; Lennox, Jeffrey L; Levy, Mitchell M; Li, Jonathan Z; Martin, Greg S; Naggie, Susanna; Pavia, Andrew T; Seam, Nitin; Simpson, Steven Q; Swindells, Susan; Tien, Phyllis; Waghmare, Alpana A; Wilson, Kevin C; Yazdany, Jinoos; Zachariah, Philip; Campbell, Danielle M; Harrison, Carly; Burgess, Timothy; Francis, Joseph; Sheikh, Virginia; Uyeki, Timothy M; Walker, Robert; Brooks, John T; Ortiz, Laura Bosque; Davey, Richard T; Doepel, Laurie K; Eisinger, Robert W; Han, Alison; Higgs, Elizabeth S; Nason, Martha C; Crew, Page; Lerner, Andrea M; Lund, Claire; Worthington, ChristopherThe development of the National Institutes of Health (NIH) COVID-19 Treatment Guidelines began in March 2020 in response to a request from the White House Coronavirus Task Force. Within 4 days of the request, the NIH COVID-19 Treatment Guidelines Panel was established and the first meeting took place (virtually-as did subsequent meetings). The Panel comprises 57 individuals representing 6 governmental agencies, 11 professional societies, and 33 medical centers, plus 2 community members, who have worked together to create and frequently update the guidelines on the basis of evidence from the most recent clinical studies available. The initial version of the guidelines was completed within 2 weeks and posted online on 21 April 2020. Initially, sparse evidence was available to guide COVID-19 treatment recommendations. However, treatment data rapidly accrued based on results from clinical studies that used various study designs and evaluated different therapeutic agents and approaches. Data have continued to evolve at a rapid pace, leading to 24 revisions and updates of the guidelines in the first year. This process has provided important lessons for responding to an unprecedented public health emergency: Providers and stakeholders are eager to access credible, current treatment guidelines; governmental agencies, professional societies, and health care leaders can work together effectively and expeditiously; panelists from various disciplines, including biostatistics, are important for quickly developing well-informed recommendations; well-powered randomized clinical trials continue to provide the most compelling evidence to guide treatment recommendations; treatment recommendations need to be developed in a confidential setting free from external pressures; development of a user-friendly, web-based format for communicating with health care providers requires substantial administrative support; and frequent updates are necessary as clinical evidence rapidly emerges.Item Open Access Development and evaluation of a novel training program to build study staff skills in equitable and inclusive engagement, recruitment, and retention of clinical research participants.(Journal of clinical and translational science, 2022-01) Cranfill, Jessica R; Freel, Stephanie A; Deeter, Christine E; Snyder, Denise C; Naggie, Susanna; Barrett, Nadine J; Roberts, Jamie NBackground
Adequate equitable recruitment of underrepresented groups in clinical research and trials is a national problem and remains a daunting challenge to translating research discoveries into effective healthcare practices. Engagement, recruitment, and retention (ER&R) training programs for Clinical Research Professionals (CRPs) often focus on policies and regulations. Although some training on the importance of diversity and inclusion in clinical research participation has recently been developed, there remains a need for training that couples critical equity, diversity, and inclusion (EDI) concepts with skill development in effective recruitment and retention strategies, regulations, and best practices.Approach and methods
We developed the ER&R Certificate program as a holistic approach to provide Duke University CRPs the opportunity to build competency in gap areas and to increase comfort in championing equitable partnerships with clinical research participants. The thirteen core and elective courses include blended learning elements, such as e-learning and wiki journaling prompts, to facilitate meaningful discussions. Pre- and post-assessments administered to CRP program participants and their managers assessed program impact on CRP skills in ER&R tasks and comfort in equitable, diverse, and inclusive engagement of clinical research participants.Results and discussion
Results from the first two cohorts indicate that CRPs perceived growth in their own comfort with program learning objectives, especially those centered on participant partnership and EDI principles, and most managers witnessed growth in competence and responsibility for ER&R-related tasks. Results suggest value in offering CRPs robust training programs that integrate EDI and ER&R training.Item Open Access Direct-Acting Antivirals Improve Access to Care and Cure for Patients With HIV and Chronic HCV Infection.(Open Forum Infect Dis, 2018-01) Collins, Lauren F; Chan, Austin; Zheng, Jiayin; Chow, Shein-Chung; Wilder, Julius M; Muir, Andrew J; Naggie, SusannaBackground: Direct-acting antivirals (DAA) as curative therapy for hepatitis C virus (HCV) infection offer >95% sustained virologic response (SVR), including in patients with human immunodeficiency virus (HIV) infection. Despite improved safety and efficacy of HCV treatment, challenges remain, including drug-drug interactions between DAA and antiretroviral therapy (ART) and restrictions on access by payers. Methods: We performed a retrospective cohort study of all HIV/HCV co-infected and HCV mono-infected patients captured in care at our institution from 2011-2015, reflecting the DAA era, to determine treatment uptake and SVR, and to elucidate barriers to accessing DAA for co-infected patients. Results: We identified 9290 patients with HCV mono-infection and 507 with HIV/HCV co-infection. Compared to mono-infected patients, co-infected patients were younger and more likely to be male and African-American. For both groups, treatment uptake improved from the DAA/pegylated interferon (PEGIFN)-ribavirin to IFN-free DAA era. One-third of co-infected patients in the IFN-free DAA era required ART switch and nearly all remained virologically suppressed after 6 months. We observed SVR >95% for most patient subgroups including those with co-infection, prior treatment-experience, and cirrhosis. Predictors of access to DAA for co-infected patients included Caucasian race, CD4 count ≥200 cells/mm3, HIV virologic suppression and cirrhosis. Time to approval of DAA was longest for patients insured by Medicaid, followed by private insurance and Medicare. Conclusions: DAA therapy has significantly improved access to HCV treatment and high SVR is independent of HIV status. However, in order to realize cure for all, barriers and disparities in access need to be urgently addressed.Item Open Access Feasibility and willingness-to-pay for integrated community-based tuberculosis testing.(BMC Infect Dis, 2011-11-02) Goswami, Neela D; Hecker, Emily; Holland, David P; Naggie, Susanna; Cox, Gary M; Mosher, Ann; Turner, Debbie; Torres, Yvonne; Vickery, Carter; Ahearn, Marshall A; Blain, Michela LM; Rasmussen, Petra; Stout, Jason EBACKGROUND: Community-based screening for TB, combined with HIV and syphilis testing, faces a number of barriers. One significant barrier is the value that target communities place on such screening. METHODS: Integrated testing for TB, HIV, and syphilis was performed in neighborhoods identified using geographic information systems-based disease mapping. TB testing included skin testing and interferon gamma release assays. Subjects completed a survey describing disease risk factors, healthcare access, healthcare utilization, and willingness to pay for integrated testing. RESULTS: Behavioral and social risk factors among the 113 subjects were prevalent (71% prior incarceration, 27% prior or current crack cocaine use, 35% homelessness), and only 38% had a regular healthcare provider. The initial 24 subjects reported that they would be willing to pay a median $20 (IQR: 0-100) for HIV testing and $10 (IQR: 0-100) for TB testing when the question was asked in an open-ended fashion, but when the question was changed to a multiple-choice format, the next 89 subjects reported that they would pay a median $5 for testing, and 23% reported that they would either not pay anything to get tested or would need to be paid $5 to get tested for TB, HIV, or syphilis. Among persons who received tuberculin skin testing, only 14/78 (18%) participants returned to have their skin tests read. Only 14/109 (13%) persons who underwent HIV testing returned to receive their HIV results. CONCLUSION: The relatively high-risk persons screened in this community outreach study placed low value on testing. Reported willingness to pay for such testing, while low, likely overestimated the true willingness to pay. Successful TB, HIV, and syphilis integrated testing programs in high risk populations will likely require one-visit diagnostic testing and incentives.Item Open Access Geographic information system-based screening for TB, HIV, and syphilis (GIS-THIS): a cross-sectional study.(PLoS One, 2012) Goswami, Neela D; Hecker, Emily J; Vickery, Carter; Ahearn, Marshall A; Cox, Gary M; Holland, David P; Naggie, Susanna; Piedrahita, Carla; Mosher, Ann; Torres, Yvonne; Norton, Brianna L; Suchindran, Sujit; Park, Paul H; Turner, Debbie; Stout, Jason EOBJECTIVE: To determine the feasibility and case detection rate of a geographic information systems (GIS)-based integrated community screening strategy for tuberculosis, syphilis, and human immunodeficiency virus (HIV). DESIGN: Prospective cross-sectional study of all participants presenting to geographic hot spot screenings in Wake County, North Carolina. METHODS: The residences of tuberculosis, HIV, and syphilis cases incident between 1/1/05-12/31/07 were mapped. Areas with high densities of all 3 diseases were designated "hot spots." Combined screening for tuberculosis, HIV, and syphilis were conducted at the hot spots; participants with positive tests were referred to the health department. RESULTS AND CONCLUSIONS: Participants (N = 247) reported high-risk characteristics: 67% previously incarcerated, 40% had lived in a homeless shelter, and 29% had a history of crack cocaine use. However, 34% reported never having been tested for HIV, and 41% did not recall prior tuberculin skin testing. Screening identified 3% (8/240) of participants with HIV infection, 1% (3/239) with untreated syphilis, and 15% (36/234) with latent tuberculosis infection. Of the eight persons with HIV, one was newly diagnosed and co-infected with latent tuberculosis; he was treated for latent TB and linked to an HIV provider. Two other HIV-positive persons had fallen out of care, and as a result of the study were linked back into HIV clinics. Of 27 persons with latent tuberculosis offered therapy, nine initiated and three completed treatment. GIS-based screening can effectively penetrate populations with high disease burden and poor healthcare access. Linkage to care remains challenging and will require creative interventions to impact morbidity.
