Antiretrovirals and Weight Change: Weighing the Evidence. Clin Infect Dis 2024:ciae191. [PMID: 38606799 DOI: 10.1093/cid/ciae191] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Revised: 02/27/2024] [Accepted: 04/04/2024] [Indexed: 04/13/2024] Open
Abstract
Body weight is influenced by an interplay of individual and environmental factors. In people with HIV (PWH), weight is also influenced by disease status with loss accompanying disease progression that is reversed with effective antiretroviral therapy (ART). Weight changes in comparative ART trials differ by regimen, with greater gains observed with the integrase strand transfer inhibitors (INSTIs) dolutegravir and bictegravir, particularly when co-administered with tenofovir alafenamide fumarate (TAF), compared to regimens that include agents such as tenofovir disoproxil fumarate (TDF) that attenuate weight gain. We review weight changes in major randomized trials of pre-exposure prophylaxis (PrEP) and initial and switch HIV therapy, highlighting the challenges to assessing the role of ART in weight change. This examination forms the basis for a model that questions assumptions regarding an association between INSTI and TAF and excessive weight gain and calls for more careful consideration of these data when making HIV treatment decisions.

Abstract
Long-acting injectable antiretroviral therapy (LA-ART) expands treatment options for people living with HIV (PLWH). This qualitative study characterizes LA-ART awareness, perceptions, and preferences among PLWH engaged in HIV care. From 2019 through 2021, we conducted semistructured in-depth interviews with 71 PLWH sampled from three clinics in three U.S. settings (North Carolina, Washington, DC, Massachusetts). Transcripts were analyzed using narrative and thematic techniques. Participant mean age was 46 years (range 24-72); most were cisgender men (55%) and virally suppressed (73%). Most participants had not heard of LA-ART and reacted with a mix of excitement and cautiousness. Potential LA-ART benefits included easier adherence, privacy, and effectiveness; concerns included effectiveness, side effects, costs, and increased clinic visits. Participants appreciated that LA-ART could support achieving and sustaining viral suppression. To inform their decision, participants wanted more information and convenient access and administration. Findings indicated that a shared decision-making approach and economic and logistical support for PLWH could facilitate LA-ART uptake.

Abstract
BACKGROUND There is little information regarding severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA as a predictor for clinical outcomes in outpatients with mild-to-moderate coronavirus disease 2019 (COVID-19). METHODS Anterior nasal (AN) and plasma SARS-CoV-2 RNA data from 2115 nonhospitalized adults who received monoclonal antibodies (mAbs) or placebo in the ACTIV-2/A5401 trial were analyzed for associations with hospitalization or death. RESULTS One hundred two participants were hospitalized or died through 28 days of follow-up. Higher day 0 (pretreatment) AN RNA was associated with increasing risk of hospitalization/death (risk ratio [RR], 1.24 per log10 copies/mL [95% confidence interval {CI}, 1.04-1.49]) among placebo recipients, ranging from 3% to 16% for <2 to ≥6 log10 copies/mL. Although only 1% had quantifiable levels, there was a similar trend across day 0 plasma RNA categories. Higher day 3 AN RNA was associated with subsequent hospitalization/death among placebo recipients (RR, 1.42 per log10 copies/mL [95% CI, 1.00-2.03]), but not mAb recipients (RR, 1.02 per log10 copies/mL [95% CI, 0.68-1.56]). The proportion of treatment effect (reduction in hospitalizations/deaths after day 3 for mAb vs placebo) explained by day 3 AN RNA was 8%. CONCLUSIONS SARS-CoV-2 RNA levels are predictive of hospitalization/death in the natural history setting, but AN RNA levels may not be a reliable surrogate marker of mAb treatment effect in COVID-19 trials.

Phase 2 Safety and Antiviral Activity of SAB-185, a Novel Polyclonal Antibody Therapy for Nonhospitalized Adults With COVID-19. J Infect Dis 2023; 228:133-142. [PMID: 36661240 PMCID: PMC10345463 DOI: 10.1093/infdis/jiad013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Revised: 01/04/2023] [Accepted: 01/17/2023] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND SAB-185, a novel fully human IgG polyclonal immunoglobulin product, underwent phase 2 evaluation for nonhospitalized adults with mild-moderate coronavirus disease 2019 (COVID-19). METHODS Participants received intravenous SAB-185 3840 units/kg (low-dose) or placebo, or 10 240 units/kg (high-dose) or placebo. Primary outcome measures were nasopharyngeal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA < lower limit of quantification (LLOQ) at study days 3, 7, and 14, time to symptomatic improvement, and safety through day 28. RESULTS Two-hundred thirteen participants received low-dose SAB-185/placebo (n = 107/106) and 215 high-dose SAB-185/placebo (n = 110/105). The proportions with SARS-CoV-2 RNA < LLOQ were higher for SAB-185 versus placebo at days 3 and 7 and similar at day 14, and significantly higher at day 7 for high-dose SAB-185 versus placebo only, relative risk 1.23 (95% confidence interval, 1.01-1.49). At day 3, SARS-CoV-2 RNA levels were lower with low-dose and high-dose SAB-185 versus placebo: differences in medians of -0.78 log10 copies/mL (P = .08) and -0.71 log10 copies/mL (P = .10), respectively. No difference was observed in time to symptom improvement: median 11/10 days (P = .24) for low-dose SAB-185/placebo and 8/10 days (P = .50) for high-dose SAB-185/placebo. Grade ≥3 adverse events occurred in 5%/13% of low-dose SAB-185/placebo and 9%/12% of high-dose SAB-185/placebo. CONCLUSIONS SAB-185 was safe and generally well tolerated and demonstrated modest antiviral activity in predominantly low-risk nonhospitalized adults with COVID-19. Clinical Trials Registration. NCT04518410.

Abstract
BACKGROUND Development of safe and effective SARS-CoV-2 therapeutics is a high priority. Amubarvimab and romlusevimab are noncompeting anti-SARS-CoV-2 monoclonal antibodies with an extended half-life. OBJECTIVE To assess the safety and efficacy of amubarvimab plus romlusevimab. DESIGN Randomized, placebo-controlled, phase 2 and 3 platform trial. (ClinicalTrials.gov: NCT04518410). SETTING Nonhospitalized patients with COVID-19 in the United States, Brazil, South Africa, Mexico, Argentina, and the Philippines. PATIENTS Adults within 10 days onset of symptomatic SARS-CoV-2 infection who are at high risk for clinical progression. INTERVENTION Combination of monoclonal antibodies amubarvimab plus romlusevimab or placebo. MEASUREMENTS Nasopharyngeal and anterior nasal swabs for SARS-CoV-2, COVID-19 symptoms, safety, and progression to hospitalization or death. RESULTS Eight-hundred and seven participants who initiated the study intervention were included in the phase 3 analysis. Median age was 49 years (quartiles, 39 to 58); 51% were female, 18% were Black, and 50% were Hispanic or Latino. Median time from symptom onset at study entry was 6 days (quartiles, 4 to 7). Hospitalizations and/or death occurred in 9 (2.3%) participants in the amubarvimab plus romlusevimab group compared with 44 (10.7%) in the placebo group, with an estimated 79% reduction in events (P < 0.001). This reduction was similar between participants with 5 or less and more than 5 days of symptoms at study entry. Grade 3 or higher treatment-emergent adverse events through day 28 were seen less frequently among participants randomly assigned to amubarvimab plus romlusevimab (7.3%) than placebo (16.1%) (P < 0.001), with no severe infusion reactions or drug-related serious adverse events. LIMITATION The study population was mostly unvaccinated against COVID-19 and enrolled before the spread of Omicron variants and subvariants. CONCLUSION Amubarvimab plus romlusevimab was safe and significantly reduced the risk for hospitalization and/or death among nonhospitalized adults with mild to moderate SARS-CoV-2 infection at high risk for progression to severe disease.

Safety and Efficacy of Combined Tixagevimab and Cilgavimab Administered Intramuscularly or Intravenously in Nonhospitalized Patients With COVID-19: 2 Randomized Clinical Trials. JAMA Netw Open 2023; 6:e2310039. [PMID: 37099295 PMCID: PMC10134004 DOI: 10.1001/jamanetworkopen.2023.10039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Accepted: 02/26/2023] [Indexed: 04/27/2023] Open
Abstract
Importance Development of effective, scalable therapeutics for SARS-CoV-2 is a priority. Objective To test the efficacy of combined tixagevimab and cilgavimab monoclonal antibodies for early COVID-19 treatment. Design, Setting, and Participants Two phase 2 randomized blinded placebo-controlled clinical trials within the Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV)-2/A5401 platform were performed at US ambulatory sites. Nonhospitalized adults 18 years or older within 10 days of positive SARS-CoV-2 test and symptom onset were eligible and were enrolled from February 1 to May 31, 2021. Interventions Tixagevimab-cilgavimab, 300 mg (150 mg of each component) given intravenously (IV) or 600 mg (300 mg of each component) given intramuscularly (IM) in the lateral thigh, or pooled placebo. Main Outcomes and Measures Coprimary outcomes were time to symptom improvement through 28 days; nasopharyngeal SARS-CoV-2 RNA below the lower limit of quantification (LLOQ) on days 3, 7, or 14; and treatment-emergent grade 3 or higher adverse events through 28 days. Results A total of 229 participants were randomized for the IM study and 119 were randomized for the IV study. The primary modified intention-to-treat population included 223 participants who initiated IM tixagevimab-cilgavimab (n = 106) or placebo treatment (n = 117) (median age, 39 [IQR, 30-48] years; 113 [50.7%] were men) and 114 who initiated IV tixagevimab-cilgavimab (n = 58) or placebo treatment (n = 56) (median age, 44 [IQR, 35-54] years; 67 [58.8%] were women). Enrollment in the IV study was stopped early based on a decision to focus on IM product development. Participants were enrolled at a median of 6 (IQR, 4-7) days from COVID-19 symptom onset. Significant differences in time to symptom improvement were not observed for IM tixagevimab-cilgavimab vs placebo or IV tixagevimab-cilgavimab vs placebo. A greater proportion in the IM tixagevimab-cilgavimab arm (69 of 86 [80.2%]) than placebo (62 of 96 [64.6%]) had nasopharyngeal SARS-CoV-2 RNA below LLOQ at day 7 (adjusted risk ratio, 1.33 [95% CI, 1.12-1.57]) but not days 3 and 14; the joint test across time points favored treatment (P = .003). Differences in the proportion below LLOQ were not observed for IV tixagevimab-cilgavimab vs placebo at any of the specified time points. There were no safety signals with either administration route. Conclusions In these 2 phase 2 randomized clinical trials, IM or IV tixagevimab-cilgavimab was safe but did not change time to symptom improvement. Antiviral activity was more evident in the larger IM trial. Trial Registration ClinicalTrials.gov Identifier: NCT04518410.

Abstract
BACKGROUND Lingering symptoms have been reported by survivors of Ebola virus disease (EVD). There are few data describing the persistence and severity of these symptoms over time. METHODS Symptoms of headache, fatigue, joint pain, muscle pain, hearing loss, visual loss, numbness of hands or feet were longitudinally assessed among participants in the Liberian Ebola Survivors Cohort study. Generalized linear mixed effects models, adjusted for sex and age, were used to calculate the odds of reporting a symptom and it being rated as highly interfering with life. RESULTS From June 2015 to June 2016, 326 survivors were enrolled a median of 389 days (range 51-614) from acute EVD. At baseline 75.2% reported at least 1 symptom; 85.8% were highly interfering with life. Over a median follow-up of 5.9 years, reporting of any symptom declined (odds ratio for each 90 days of follow-up = 0.96, 95% confidence interval [CI]: .95, .97; P < .0001) with all symptoms declining except for numbness of hands or feet. Rating of any symptom as highly interfering decreased over time. Among 311 with 5 years of follow-up, 52% (n = 161) reported a symptom and 29% (n = 47) of these as highly interfering with their lives. CONCLUSIONS Major post-EVD symptoms are common early during convalescence and decline over time along with severity. However, even 5 years after acute infection, a majority continue to have symptoms and, for many, these continue to greatly impact their lives. These findings call for investigations to identify the mechanisms of post-EVD sequelae and therapeutic interventions to benefit the thousands of effected EVD survivors.

Abstract
Background SARS-CoV-2 continues to spread and the development of safe and effective therapeutics for the prevention of severe disease remains a priority. BRII-196 and BRII-198 are non-competing anti-SARS-CoV-2 mAbs with YTE triple amino acid substitution in Fc to extend half-life and reduce receptor binding, that are being studied for treatment of COVID-19 in the ACTIV-2 Trial, sponsored by NIAID and led by ACTG. Methods ACTIV-2 evaluates safety/efficacy of investigational agents for treatment of non-hospitalized adults with mild-moderate COVID-19 under a randomized, blinded, controlled adaptive platform. BRII-196/BRII-198 (1000 mg each) as a single dose given as sequential infusions, or placebo to those at high risk of clinical progression (i.e., age ≥ 60 years or presence of other medical conditions) within 10 days of symptom onset and positive test for SARS-CoV-2. The primary endpoint was hospitalization and/or death through day 28. We report Phase 3 BRII-196/BRII-198 trial results per DSMB recommendation following an interim analysis. Results Between January and July 2021, 837 participants (418 active, 419 placebo) from sites in the US (66%), Brazil, South Africa, Mexico, Argentina and the Philippines were randomized and received study product at time of emerging variants. Median age 49 years (Q1, Q3: 39, 58), 51% female, 17% Black/African-American and 49% Hispanic/Latino, with median 6 days from symptom onset. At interim analysis 71% and 97% had a day 28 and 7 visit, respectively. For all available data at interim review, BRII-196/BRII-198 compared to placebo had fewer hospitalizations (12 vs. 45) and deaths (1 vs. 9). At day 28 of follow-up, there was an estimated 78% reduction in hospitalization and/or death (2.4 vs. 11.1%), relative risk 0.22 (95% CI: 0.05, 0.86), P=0.00001 (nominal one-sided). Grade 3 or higher adverse events (AEs) were observed less frequently among BRII-196/BRII-198 participants than placebo (3.8% vs. 13.4%) with no severe infusion reactions or drug related serious AEs. Conclusion BRII-196/BRII-198 was safe, well-tolerated, and demonstrated significant reduction compared to placebo in the risk of hospitalization and/or death among adults with mild-moderate COVID-19 at high risk for progression to severe disease.

The impact of semen testing for Ebola virus RNA on sexual behavior of male Ebola survivors in Liberia. PLoS Negl Trop Dis 2020; 14:e0008556. [PMID: 32925964 PMCID: PMC7515181 DOI: 10.1371/journal.pntd.0008556] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2020] [Revised: 09/24/2020] [Accepted: 07/02/2020] [Indexed: 12/31/2022] Open
Abstract
Sexual transmission of Ebola virus (EBOV) is well established and has been implicated in multiple resurgences during the West African Ebola epidemic. Given the persistence of viral RNA in semen, guidelines from the World Health Organization (WHO) recommend abstinence or condom use for at least 1 year or until two semen PCR tests are negative. To better understand the impact of semen testing on sexual behavior, male EVD survivors were surveyed regarding their sexual behavior before and after semen testing. Of the 171 men who enrolled, 148 reported being sexually active following discharge from an ETU with 59% reporting episodes of condomless sex. At least one semen sample for testing was provided by 149 men and 13 of these men had EBOV RNA detected in their semen. When comparing sexual behaviors before and after semen testing, a positive semen test result had limited impact on behavior. Of those with seminal EBOV RNA detected, 61% reported no change in behavior pre- and post-semen testing with 46% engaging in condomless sex before and after testing and only 1 adopted safer sex behaviors following receipt of a positive result. Similarly, among men with undetectable EBOV in their semen, 66% reported no change in sexual behaviors with semen testing, with 55% forgoing condoms during sex. In only 11% was a negative semen result followed by abandoning condoms. There were no known sexual transmission events of Ebola virus in this cohort despite viral presence in semen during periods of condomless sex. This highlights the need to better understand the infectious potential of viral RNA persistence and determine what constitutes effective counseling for survivors and their partners. Ebola virus (EBOV) is established as a sexually transmitted infection, however there is limited information on the sexual behaviors of Ebola survivors. We surveyed a cohort of male Ebola survivors regarding sexual activity and condom use and offered semen testing to assess EBOV persistence in semen. We found that a large majority of men who were sexually active prior to contracting Ebola Virus Disease remained sexually active after their recovery with most reporting only intermittent condom use. Semen testing for the presence of Ebola virus had limited impact on sexual behaviors, with most continuing to report engaging in condomless sex whether EBOV was detected or not. This finding has implications for use of semen testing for outbreak control as well as counseling for Ebola survivors and their partners.

Abstract
Background Survivors of the 2014–2016 West Africa Ebola epidemic have been reported to suffer high levels of stigmatization after return to their communities. We sought to characterize the stigma encountered by a cohort of Ebola survivors in Liberia over time. Methods Ebola-related stigma was assessed from June 2015 to August 2017 in 299 adolescent and adult Liberian Ebola Survivor Cohort participants at three month intervals using adapted HIV stigma scales scored from 0 to 10 according to the proportion of answers indicating stigmatization. Findings The median time from Ebola Virus Disease (EVD) to study entry was 393 days (IQR 336–492). Participants (43% female) had a median age of 31 (IQR 25–40) years. Mean self-reported stigma levels were greater at baseline (6.28 ± 0.15 [IQR: 4.38–8.75]) compared to the first post-baseline visit (0.60 ± 0.10 [IQR: 0–0]; p<0.0001). During follow-up, stigma levels were stable. Baseline stigma significantly increased during enrollment and following clusters of Ebola re-emergence in Liberia. Survivors encountered primarily enacted and perceived external stigma rather than internalized stigma. Conclusions Ebola-related stigma was prevalent among Liberian survivors more than a year after EVD recovery. Self-reported stigma was greater in the period before cohort enrollment; however, some degree of stigmatization persisted years after EVD. Transient rises in stigma were observed following episodic Ebola re-emergence of EVD in Liberia. During future EVD outbreaks, enhanced public health interventions designed to prevent and mitigate Ebola-related stigma that is enacted and external should be implemented to support survivor recovery and community re-integration.

Abstract
Background As people with HIV are living longer, focusing quality improvement (QI) initiatives on health maintenance and comprehensive patient-centered care is essential. This QI study evaluated chart-document performance in selected HIV care practices across the United States. Methods Participants were randomly selected from 11 Ryan White-funded HIV clinics in community (n = 7), hospital (n = 3), and academic (n = 1) settings. At baseline, 200 consecutive charts (~20 per clinic) were reviewed for documentation of guideline-directed practices. Clinic teams participated in audit-feedback interventions to develop improvement plans. Three months later, consecutive charts were reviewed according to baseline methods. Chi-square tests were conducted to analyze pre- and post-intervention differences. Results Significant improvements were seen in sexually transmitted infection (STI) screening, and patient counseling on sexual risk, pre-exposure prophylaxis (PrEP), and antiretroviral therapy (ART). Documentation of several health maintenance measures improved significantly. Conclusion Audit-feedback of QI measures improved performance. This approach can inform future QI initiatives.

Abstract
Background Among individuals living with human immunodeficiency virus (HIV), pulmonary complications are the most frequent cause of morbidity and mortality. Although bacterial and fungal pathogens are well-described etiologies of lung disease, the role of respiratory viruses remains poorly understood. We sought to describe the burden of respiratory viral illness in HIV-infected inpatients admitted to our tertiary care center. Methods All HIV-infected inpatients from August 2015 to March 2018 were approached if they presented with respiratory symptoms, defined as cough, dyspnea, sore throat, rhinorrhea, wheezing, or stridor. Eighty patients were enrolled. After obtaining informed consent, nasopharyngeal swabs and blood were collected. If the subject underwent bronchoscopy per the treating physician, excess bronchoalveolar lavage (BAL) sample was collected. Demographic and clinical data were recorded for each subject. Multiplex PCR testing of all respiratory samples was performed. Results Of the 70 HIV-infected patients that have undergone complete analysis, 23 (33%) tested positive for respiratory viruses. Of these, 11 (48%) were positive for rhinovirus, 3 were positive for influenza A (13%), 2 for parainfluenza 3 (9%), 2 for coronavirus (9%), and one each tested positive for adenovirus, parainfluenza 4, respiratory syncytial virus and influenza B. One patient had co-infection with rhinovirus and human metapneumovirus. Patients infected with a respiratory virus had severe illness as nearly half (10/23; 48%) required intensive care, 5 (22%) required mechanical ventilation, 4 (17%) were discharged to a higher level of care, and 3 (13%) died. Conclusion The role of respiratory viruses on the lung health of HIV-infected patients is poorly defined. In this study, respiratory viruses were identified in over a third of HIV-infected inpatients, representing a substantial disease burden. Moreover, these patients demonstrated significant disease severity. Given these findings, there is a need for future studies of viral infections in HIV-infected individuals to elucidate mechanisms of susceptibility to reduce the burden of pulmonary morbidity in this vulnerable population.

Abstract
More than 1% of all adults in the United States are currently in a jail or prison. This mass incarceration, particularly of African American men, fosters conditions that facilitate the spread of HIV in communities where both HIV and incarceration are endemic. Recognition of the role of mass incarceration in the perpetuation of the HIV epidemic is essential to development of effective HIV prevention policies.

Abstract
Incarcerated populations have relatively high HIV prevalence but little has been reported about their aggregate HIV risk behaviors or perceptions of risk. A random selection of HIV-negative men (n = 855) entering a US state prison system were surveyed to assess five risk behaviors and his self-perceived HIV risk. Using multivariate logistic regression, we identified factors associated with having elevated actual but low perceived risk (EALPR). Of the 826 men with complete data, 88% were at elevated risk. While 64% of the sample had risk perceptions concordant with their actual risk, 14% had EALPR (with the remainder at low actual but high perceived risk). EALPR rates were lower in those with a pre-incarceration HIV test but higher for those with a negative prison entry HIV test. HIV testing counseling should assess for discordance between actual and perceived risk and communicate the continued risk of HIV despite a negative result.

Abstract
Among 149 men who survived Ebola virus disease (EVD) and donated semen 260–1016 days after EVD onset, Ebola virus (EBOV) ribonucleic acid (RNA) was detected in 13 (9%). Of 137 men who donated semen 2 years after EVD onset, 11 (8%) had an EBOV RNA-positive specimen. The mechanism underlying the persistence of EBOV RNA in semen is unclear, and it is unclear whether the detection of viral RNA represents the presence of infectious virus.

Abstract
OBJECTIVES HIV treatment guidelines endorse switching or simplification of antiretroviral therapy in therapy-experienced patients with suppressed viraemia; ritonavir discontinuation may also enhance tolerability and reduce long-term adverse events (AEs). This open-label, multicentre, noninferiority study enrolled HIV-1-infected, treatment-experienced adults with confirmed HIV-1 RNA ≤ 75 HIV-1 RNA copies/mL currently receiving tenofovir/emtricitabine + atazanavir/ritonavir (TDF/FTC + ATV/r) for ≥ 6 months with no reported history of virological failure. METHODS Participants were randomized 1:2 to continue current treatment or switch to abacavir/lamivudine + atazanavir (ABC/3TC + ATV). Endpoints included the proportion of participants with HIV-1 RNA < 50 copies/mL by time to loss of virological response (TLOVR), AEs, fasting lipids, and inflammatory, coagulation, bone and renal biomarkers. RESULTS After 48 weeks, 76% (152 of 199) of ABC/3TC + ATV-treated and 79% (77 of 97) of TDF/FTC + ATV/r-treated participants had HIV-1 RNA < 50 copies/mL (TLOVR; P = 0.564). Other efficacy analyses yielded similar results. Rates of new grade 2-4 AEs were 45% in both groups, but an excess of hyperbilirubinaemia made the rate of treatment-emergent grade 3-4 laboratory abnormalities higher with TDF/FTC + ATV/r (36%) compared with ABC/3TC + ATV (19%). Most fasting lipid levels remained stable over time; high-density lipoprotein (HDL) cholesterol increased modestly in ABC/3TC + ATV-treated participants. Bone and renal biomarkers improved significantly between baseline and week 48 in participants taking ABC/3TC + ATV and were stable in participants taking TDF/FTC + ATV/r. No significant changes occurred in any inflammatory or coagulation biomarker within or between treatment groups. CONCLUSIONS The ABC/3TC + ATV treatment-switch group had similar viral suppression rates up to 48 weeks to the TDF/FTC + ATV/r comparator group, with lower rates of moderate- to high-grade hyperbilirubinaemia and improvements in bone and renal biomarkers.

Abstract
BACKGROUND Reconstitution of immune function during potent antiretroviral therapy can prompt discontinuation of maintenance cytomegalovirus (CMV) therapy but has also been associated with sight-threatening inflammatory conditions including immune recovery uveitis (IRU). METHOD Patients with inactive CMV retinitis and a CD4+ cell count above 100/mm3, receiving CMV therapy and stable combination antiretroviral therapy, were assigned to one of two groups based on willingness to discontinue CMV therapy. RESULTS Thirty-eight participants were enrolled: 28 discontinued anti-CMV therapy (Group 1) and 10 continued CMV treatment (Group 2). Median on-study follow-up was 16 months. One Group 1 participant who experienced an increase in plasma HIV viral load and a decline in CD4+ cell count developed confirmed progression of CMV retinitis. Progression or reactivation CMV retinitis was not observed among Group 2. IRU was present at study entry in 3 participants. Six participants in Group 1 and 3 participants in Group 2 developed IRU on-study. CMV viremia was not detected in any participants, and urinary shedding of CMV was intermittent. CONCLUSION Recurrence of CMV retinitis following discontinuation of anti-CMV therapy among patients with antiretroviral-induced increases in CD4+ cell count was rare. However, IRU was common in both those who maintained and discontinued anti-CMV therapy.

Abstract
BACKGROUND In the USA, women, racial/ethnic minorities and persons who acquire HIV infection through heterosexual intercourse represent an increasing proportion of HIV-infected persons, and yet are frequently underrepresented in clinical trials. We assessed the demographic predictors of trial participation in antiretroviral-naïve patients. METHODS Patients were characterized as trial participants if highly active antiretroviral therapy (HAART) was initiated within a clinical trial. Prevalence ratios (PRs) were obtained using binomial regression. RESULTS Between 1996 and 2006, 30% of 738 treatment-naïve patients initiated HAART in a clinical trial. Trial participation rates for men who have sex with men (MSM), heterosexual men, and women were respectively 36.5, 29.6 and 24.3%. After adjustment for other factors, heterosexual men appeared less likely to participate in trials compared with MSM [PR 0.79, 95% confidence interval (CI) 0.57, 1.11], while women were as likely to participate as MSM (PR 0.97, 95% CI 0.68, 1.39). The participation rate in Black patients (25.9%) was lower compared with non-Black patients (37.5%) (adjusted PR 0.80, 95% CI 0.60, 1.06). CONCLUSIONS In our clinical setting, gender did not appear to impact participation in HIV treatment trials, but Black patients were slightly less likely to participate in these trials. Considering the substantial proportion of HIV-infected patients who are Black, future trials need to consider strategies to incorporate such underrepresented populations.

Abstract
The selection of antiretroviral therapy for HIV-infected persons initiating treatment is influenced by numerous factors, including efficacy, safety, convenience, drug interactions, and cost, among others. Guidelines have been developed to assist the clinician in choosing regimens that have been found to be effective in clinical studies. Understanding the recommendations of the major US treatment guideline for initial HIV therapy is essential for clinicians caring for such patients.

Abstract
PURPOSE To describe cytomegalovirus (CMV) end-organ disease (EOD) rate in AIDS patients with low CD4+ cell count despite HAART who were enrolled in a randomized, placebo-controlled trial of preemptive valganciclovir (VGCV) to prevent CMV EOD in those with CMV viremia. METHODS Subjects (N = 338) were HIV-infected with CD4+ count <100 cells/mm3, plasma HIV RNA >400 copies/mL, and on stable or no HAART. All underwent plasma CMV DNA PCR testing every 8 weeks (Step 1); those with detectable CMV DNA were randomized to VGCV or placebo (Step 2). RESULTS Plasma CMV DNA was detected in 68 (20%), of whom 4 developed CMV EOD. During Step 1, 53 died. Of the 47 who entered Step 2 (24 VGCV, 23 placebo), CMV EOD was diagnosed in 10 (4 VGCV, 6 placebo) and 15 died (7 VGCV, 8 placebo). Of those randomized to placebo, 14% were diagnosed with CMV EOD at 12 months. CONCLUSIONS We observed a lower CMV EOD rate among subjects receiving HAART than predicted based on published literature. However, mortality was high in this study. Our findings suggest that preemptive anti-CMV therapy in patients with persistently low CD4+ cell counts in the current treatment era may not be warranted given the low incidence of CMV EOD and high all-cause mortality observed in this study population.

Abstract
Patients with HIV infection and their clinicians are increasingly considering the risk of metabolic complications when choosing HIV therapies. Fear of the potential metabolic consequences of antiretroviral agents may lead some to delay HIV therapy and threaten medication adherence once treatment is initiated. Until recently, there has been limited objective study of the relative contributions of specific antiretrovirals and particular combinations of these drugs to dyslipidemia and body fat changes; in lieu of data, unsupported perceptions regarding the links between therapies and these metabolic complications have predominated. Over the past year, a number of comparative clinical trials have clarified the association between exposure to antiretrovirals and lipid and fat disorders and, in some cases, have yielded results that challenge our perceptions regarding the causes of these complications.

Abstract
Changes in fat distribution, dyslipidemia, disordered glucose metabolism, and lactic acidosis have emerged as significant challenges to the treatment of human immunodeficiency virus (HIV) infection. Over the past decade, numerous investigations have been conducted to better define these conditions, identify risk factors associated with their development, and test potential therapeutic interventions. The lack of standardized diagnostic criteria, as well as disparate study populations and research methods, have led to conflicting data regarding the diagnosis and treatment of metabolic and body shape disorders associated with HIV infection. On the basis of a review of the medical literature published and/or data presented before April 2006, we have prepared a guide to assist the clinician in the detection and management of these complications.

Abstract
Metabolic complications of HIV therapy have emerged as a vexing problem for individuals living with HIV infection and their clinicians. These adverse effects threaten health and quality of life as well as adherence to HIV treatment. Among the most common metabolic complications confronting clinicians are body shape changes and dyslipidemia. The pathogenesis of these disorders remains elusive, challenging the development of treatment strategies particularly for fat redistribution. Switching from metabolically offensive antiretrovirals has yielded improvements in both body shape and dyslipidemia. In addition, therapeutic approaches that have been developed for the treatment of dyslipidemia in HIV-uninfected patients, can with important caveats be applied to HIV therapy-associated lipid disorders. Aggressive assessment of cardiovascular disease risk and intervention is likely to reduce the incidence of cardiovascular disorders in HIV-infected patients. Development of antiretrovirals with fewer metabolic adverse effects will reduce the incidence of these and similar disorders during HIV therapy.

Abstract
Cytomegalovirus (CMV)-immune recovery was characterized in human immunodeficiency virus (HIV)-infected patients receiving highly active antiretroviral therapy. CMV lymphocyte proliferation (LP), responder-cell frequency (RCF), and interferon (IFN)-gamma and interleukin (IL)-2 secretion were studied in CMV-seropositive HIV-infected patients and in CMV-seropositive HIV-uninfected control subjects. HIV-infected patients and control subjects had similar proportions of IL-2 and IFN-gamma, but levels were lower in HIV-infected patients. LP and RCF were significantly less frequent and of lower magnitude in HIV-infected patients. The measures of CMV cell-mediated immunity were correlated in HIV-uninfected but not in HIV-infected subjects. To investigate this, IL-2, IL-12, anti-CD28 plus anti-CD49d, or anti-IL-10 was added in vitro, with no effect on LP. However, CD8 cell depletion of mononuclear cells from HIV-infected patients increased LP responses to levels similar to those of uninfected control subjects; before depletion, only RCF correlated with CD4 cell counts, but after depletion, LP also correlated with CD4 cell counts.

Abstract
A multicenter, double-blind, randomized, placebo-controlled study was conducted to determine the safety and efficacy of thalidomide in reduced, intermittent doses for preventing recurrences of oral and esophageal aphthous ulcers in patients with human immunodeficiency virus (HIV) infection. Forty-nine HIV-infected patients whose ulcers previously had healed as a result of thalidomide therapy were randomly assigned to receive either 100 mg of oral thalidomide or placebo 3 times per week for 6 months. Ulcers recurred in 14 (61%) of 23 thalidomide-randomized patients, compared with 11 (42%) of 26 placebo-randomized patients, with no significant difference in the median time to recurrence of ulcers (P=.221). There were no changes in plasma levels of HIV RNA, tumor necrosis factor (TNF)-alpha, and soluble TNF receptor II at the time of ulcer recurrence. Adverse events among patients treated with thalidomide included neutropenia (5 patients), rash (5 patients), and peripheral sensory neuropathy (3 patients). Thalidomide in lower intermittent doses is ineffective at preventing recurrence of aphthous ulcers in HIV-infected persons.

Abstract
To determine the feasibility of cytomegalovirus (CMV)-specific cell-mediated immunity (CMI) studies using cryopreserved cells, we compared lymphocyte proliferation assays (LPA), responder cell frequency (RCF), interleukin-2 (IL-2) and interferon-gamma (IFN-gamma) production using fresh and cryopreserved peripheral blood mononuclear cells (PBMCs) from 53 HIV-infected patients and 15 uninfected controls. Qualitative CMV LPA results were concordant in >/=84% of the specimens from either HIV-infected patients or controls. Proliferation-based RCF, IL-2, and IFN-gamma comparisons showed that cryopreservation reduces the number of CMV-specific responders and decreases cytokine secretion, without changing the rank order of the results (p <.01). In contrast, the number of flow cytometry-enumerated IFN-gamma-producing CD4+ cells was not significantly changed by cryopreservation. In HIV-infected patients, the differences between fresh and frozen cell assays were not influenced by CD4 cell numbers or HIV viral load. These data indicate that cryopreserved cells are suitable for longitudinal studies of the CMV-specific immune response in HIV-infected patients and uninfected controls.

Abstract
Highly active antiretroviral therapy (HAART) for human immunodeficiency virus-1 (HIV-1) and prophylactic therapy for opportunistic infections have increased survival. Adverse effects of HAART include lipid profile alterations, diabetes mellitus, and fat redistribution. These metabolic and physical changes are called the HIV-associated lipodystrophy syndrome. A link to protease inhibitors has been suggested, and more recently to nucleoside reverse transcriptase inhibitors and factors related to duration of HIV-1 infection itself.

Abstract
A multicenter, double-blind, randomized, placebo-controlled clinical trial was conducted to determine the safety and efficacy of thalidomide for treating esophageal aphthous ulceration in persons infected with human immunodeficiency virus (HIV). Twenty-four HIV-infected patients with biopsy-confirmed aphthous ulceration of the esophagus were randomly assigned to receive either oral thalidomide, 200 mg/day, or oral placebo daily for 4 weeks. Eight (73%) of 11 patients randomized to receive thalidomide had complete healing of aphthous ulcers at the 4-week endoscopic evaluation, compared with 3 (23%) of 13 placebo-randomized patients (odds ratio, 13.82; 95% confidence interval, 1.16-823.75; P=.033). Odynophagia and impaired eating ability caused by esophageal aphthae were improved markedly by thalidomide treatment. Adverse events among patients receiving thalidomide included somnolence (4 patients), rash (2 patients), and peripheral sensory neuropathy (3 patients). Thalidomide is effective in healing aphthous ulceration of the esophagus in patients infected with HIV.

Abstract
BACKGROUND In patients with advanced human immunodeficiency virus (HIV) infection, aphthous ulceration of the mouth and oropharynx can become extensive and debilitating. Preliminary reports suggest that thalidomide may promote the healing of oral aphthous ulcers. METHODS We performed a double-blind, randomized, placebo-controlled study of thalidomide as therapy for oral aphthous ulcers in HIV-infected patients. The patients received a four-week course of either 200 mg of thalidomide or placebo orally once per day. They were evaluated weekly for the condition of the ulcers, their quality of life, and evidence of toxicity. Assays were performed for plasma tumor necrosis factor alpha (TNF-alpha), soluble TNF-alpha receptors, and HIV RNA. RESULTS Sixteen of 29 patients in the thalidomide group (55 percent) had complete healing of their aphthous ulcers after four weeks, as compared with only 2 of 28 patients in the placebo group (7 percent; odds ratio, 15; 95 percent confidence interval after adjustment for group sequential testing, 1.8 to 499; unadjusted P<0.001). Pain diminished and ability to eat improved with thalidomide treatment. The adverse effects noted with thalidomide included somnolence and rash (7 patients each), and 6 of the 29 patients discontinued treatment because of toxicity. Thalidomide treatment increased HIV RNA levels (median increase, 0.42 log10 copies per milliliter; increase with placebo, 0.05; P=0.04). With thalidomide treatment there were unexpected increases in the plasma concentrations of TNF-alpha and soluble TNF-alpha receptors. CONCLUSIONS Thalidomide is an effective treatment for aphthous ulceration of the mouth and oropharynx in patients with HIV infection.
