Abstract
PURPOSE OF REVIEW We discuss how epidemiologic studies have used observational data to estimate the effects of potential interventions on early-life environmental exposures. We summarize the value of posing questions about interventions, how a group of techniques known as "g-methods" can provide advantages for estimating intervention effects, and how investigators have grappled with the strong assumptions required for causal inference. RECENT FINDINGS We identified nine studies that estimated health effects of hypothetical interventions on early-life environmental exposures. Of these, six examined air pollution. Interventions evaluated by these studies included setting exposure levels at a specific value, shifting exposure distributions, and limiting exposure levels to less than a threshold value. Only one study linked exposure contrasts to a specific intervention on an exposure source, however. There is growing interest in estimating intervention effects of early-life environmental exposures, in part because intervention effects are directly related to possible public health actions. Future studies can build on existing work by linking research questions to specific hypothetical interventions that could reduce exposure levels. We discuss how framing questions around interventions can help overcome some of the barriers to causal inference and how advances related to machine learning may strengthen studies by sidestepping the overly restrictive assumptions of parametric regression models. By leveraging advancements in causal inference and exposure science, an intervention framework for environmental epidemiology can guide actionable solutions to improve children's environmental health.

Early versus delayed antiretroviral therapy based on genotypic resistance test: Results from a large retrospective cohort study. J Med Virol 2022; 94:3890-3899. [PMID: 35355293 PMCID: PMC9321101 DOI: 10.1002/jmv.27754] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Revised: 03/27/2022] [Accepted: 03/30/2022] [Indexed: 12/02/2022]
Abstract
Rapid start of antiretroviral therapy (ART) pending genotypic resistance test (GRT) has been recently proposed, but the effectiveness of this strategy is still debated. The rate of virological success (VS), defined as HIV‐RNA < 50 copies/ml, with and without GRT was compared in drug‐naïve individuals enrolled in the Italian ARCA cohort who started ART between 2015 and 2018. 521 individuals started ART: 397 without GRT (pre‐GRT group) and 124 following GRT (post‐GRT group). Overall, 398 (76%) were males and 30 (6%) were diagnosed with AIDS. In the pre‐GRT group, baseline CD4+ cell counts were lower (p < 0.001), and viral load was higher (p < 0.001) than in the post‐GRT group. The estimated probability of VS in pre‐GRT versus post‐GRT group was 72.54% (CI95: 67.78–76.60) versus 66.94% (CI95: 57.53–74.26) at Week 24 and 92.40% (CI95: 89.26–94.62) versus 92.92% (CI95: 86.35–96.33) at Week 48, respectively (p = 0.434). At Week 48, VS was less frequent among individuals with baseline CD4+ cell counts <200 versus >500 (90.33% vs. 97.33%), log viral load <5.00 versus >5.70 log10 cps/ml (97.17% vs 78.16%; p < 0.001), and those treated with protease inhibitors or non‐nucleoside reverse transcriptase inhibitors versus those treated with integrase strand transfer inhibitors (p < 0.001). The rate of VS does not seem to be affected by an early ART initiation pending GRT results, but it could be influenced by the composition of the ART regimen, as well as immuno‐virological parameters.

Mahar RK, McGuinness MB, Chakraborty B, Carlin JB, IJzerman MJ, Simpson JA. A scoping review of studies using observational data to optimise dynamic treatment regimens. BMC Med Res Methodol 2021; 21:39. [PMID: 33618655 PMCID: PMC7898728 DOI: 10.1186/s12874-021-01211-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Accepted: 01/19/2021] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Dynamic treatment regimens (DTRs) formalise the multi-stage and dynamic decision problems that clinicians often face when treating chronic or progressive medical conditions. Compared to randomised controlled trials, using observational data to optimise DTRs may allow a wider range of treatments to be evaluated at a lower cost. This review aimed to provide an overview of how DTRs are optimised with observational data in practice. METHODS Using the PubMed database, a scoping review of studies in which DTRs were optimised using observational data was performed in October 2020. Data extracted from eligible articles included target medical condition, source and type of data, statistical methods, and translational relevance of the included studies. RESULTS From 209 PubMed abstracts, 37 full-text articles were identified, and a further 26 were screened from the reference lists, totalling 63 articles for inclusion in a narrative data synthesis. Observational DTR models are a recent development and their application has been concentrated in a few medical areas, primarily HIV/AIDS (27, 43%), followed by cancer (8, 13%), and diabetes (6, 10%). There was substantial variation in the scope, intent, complexity, and quality between the included studies. Statistical methods that were used included inverse-probability weighting (26, 41%), the parametric G-formula (16, 25%), Q-learning (10, 16%), G-estimation (4, 6%), targeted maximum likelihood/minimum loss-based estimation (4, 6%), regret regression (3, 5%), and other less common approaches (10, 16%). Notably, studies that were primarily intended to address real-world clinical questions (18, 29%) tended to use inverse-probability weighting and the parametric G-formula, relatively well-established methods, along with a large amount of data. Studies focused on methodological developments (45, 71%) tended to be more complicated and included a demonstrative real-world application only. CONCLUSIONS As chronic and progressive conditions become more common, the need will grow for personalised treatments and methods to estimate the effects of DTRs. Observational DTR studies will be necessary, but so far their use to inform clinical practice has been limited. Focusing on simple DTRs, collecting large and rich clinical datasets, and fostering tight partnerships between content experts and data analysts may result in more clinically relevant observational DTR studies.

Abstract
OBJECTIVE To evaluate the risk of venous thromboembolism (VTE, i.e. deep vein thrombosis or pulmonary embolism, or both) following new use of NSAIDs in a long-term cohort of U.S. women. METHODS We investigated initiation of coxibs and traditional NSAIDs (excluding aspirin) and incident VTE in 39 876 women enrolled in the Women's Health Study from 1993-95 and followed with yearly questionnaires until 2012. We defined initiation as the first reported use of NSAIDs for ≥4 days per month. Incident VTE was confirmed by an end point committee. We estimated hazard ratios (HRs) and risk differences (RDs, expressed as percentages) comparing NSAID initiation with non-initiation and acetaminophen initiation (active comparator) via standardization using a propensity score that incorporated age, BMI, calendar time, and relevant medical, behavioural, and socioeconomic variables updated over time. RESULTS The HR (95% CI) for risk of VTE in the as treated analyses comparing initiation with non-initiation, was 1.5 (1.2, 1.8) for any NSAID, 1.3 (1.1, 1.7) for traditional NSAIDs, and 2.0 (1.3, 3.1) for coxibs, with 2-year RDs 0.11, 0.08 and 0.32, respectively. When comparing the risk of VTE after initiation of any NSAID with that after acetaminophen initiation, the HRs were 0.9 (0.6, 1.5), 0.9 (0.5, 1.5) and 1.4 (0.6, 3.4), with 2-year RDs 0.03, -0.01, and 0.13, respectively. CONCLUSION New use of NSAIDs was associated with increased VTE risk compared with non-use, but the association was null or diminished when compared with acetaminophen initiation. Elevated VTE risks associated with NSAID use in observational studies may in part reflect different baseline risks among individuals who need analgesics and may overstate the risk patients incur compared with pharmacologic alternatives.

Abstract
Effect estimates from randomized trials and observational studies might not be directly comparable because of differences in study design, other than randomization, and in data analysis. We propose a 3-step procedure to facilitate meaningful comparisons of effect estimates from randomized trials and observational studies: 1) harmonization of the study protocols (eligibility criteria, treatment strategies, outcome, start and end of follow-up, causal contrast) so that the studies target the same causal effect, 2) harmonization of the data analysis to estimate the causal effect, and 3) sensitivity analyses to investigate the impact of discrepancies that could not be accounted for in the harmonization process. To illustrate our approach, we compared estimates of the effect of immediate with deferred initiation of antiretroviral therapy in individuals positive for the human immunodeficiency virus from the Strategic Timing of Antiretroviral Therapy (START) randomized trial and the observational HIV-CAUSAL Collaboration.

Abstract
IMPORTANCE Untreated HIV infection can result in significant morbidity, mortality, and HIV transmission. A 2012 review for the US Preventive Services Task Force (USPSTF) found antiretroviral therapy (ART) associated with improved clinical outcomes and decreased transmission risk in persons with CD4 cell counts less than 500/mm3. OBJECTIVE To update the 2012 review on HIV screening to inform the USPSTF. DATA SOURCES Ovid MEDLINE, the Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews from 2012 to June 2018, with surveillance through January 2019. STUDY SELECTION Nonpregnant individuals 12 years and older; randomized clinical trials (RCTs) and controlled observational studies of screening vs no screening, alternative screening strategies, earlier vs later initiation of ART, and long-term harms of ART. DATA EXTRACTION AND SYNTHESIS One investigator abstracted data; a second checked accuracy. Two investigators independently rated study quality. MAIN OUTCOMES AND MEASURES Mortality, AIDS events, quality of life, function, and HIV transmission; harms of screening and long-term (≥2 years) harms of ART; screening yield. RESULTS Eighteen new studies (5 RCTs, 11 cohort studies, and 2 systematic reviews; N = 266 563) were included, and 11 studies (2 RCTs and 9 cohort studies; N = 218 542) were carried forward from the prior USPSTF report. No study directly evaluated effects of HIV screening vs no screening on clinical outcomes or harms, or the yield of alternative screening strategies. Two newly identified RCTs conducted completely or partially in low-resource settings found ART initiation at CD4 cell counts greater than 500/mm3 associated with lower risk of a composite outcome of mortality, AIDS-defining events, or serious non-AIDS events (relative risk [RR], 0.44 [95% CI, 0.31-0.63] and RR, 0.57 [95% CI, 0.35-0.95]); results were consistent with those from a large observational study. Early ART was not associated with increased risk of cardiovascular events. Early ART initiation was associated with sustained reduction in risk of HIV transmission at 5.5 years (RR, 0.07 [95% CI, 0.02-0.22] for linked transmission). New evidence regarding the association between abacavir use and risk of cardiovascular events was inconsistent. Certain antiretroviral regimens were associated with increased risk of long-term neuropsychiatric, renal, hepatic, and bone adverse events. CONCLUSIONS AND RELEVANCE In nonpregnant adolescents and adults there was no direct evidence on the clinical benefits and harms of screening for HIV infections vs no screening, or the yield of repeat or alternative screening strategies. New evidence extends effectiveness of ART to asymptomatic individuals with CD4 cell counts greater than 500/mm3 and shows sustained reduction in risk of HIV transmission at longer-term follow-up, although certain ART regimens may be associated with increased risk of long-term harms.

Abstract
PURPOSE OF REVIEW Optimal control of HIV can be achieved by early diagnosis followed by the initiation of antiretroviral therapy (ART). Two large randomised trials (TEMPRANO and START) have recently been published documenting the clinical benefits to HIV-positive adults of early ART initiation. Main findings are reviewed with a focus on serious non-AIDS (SNA) conditions. RECENT FINDINGS Data from the two trials demonstrated that initiating ART early in the course of HIV infection resulted in marked reductions in the risk of opportunistic diseases and invasive bacterial infections. This indicates that HIV causes immune impairment in early infection that is remedied by controlling viral replication. Intriguingly, in START, a marked reduction in risk of cancers, both infection-related and unrelated types of cancers, was observed. Like the findings for opportunistic infections, this anti-cancer effect of early ART shows how the immune system influences important pro-oncogenic processes. In START, there was also some evidence suggesting that early ART initiation preserved kidney function, although the clinical consequence of this remains unclear. Conversely, while no adverse effects were evident, the trials did not demonstrate a clear effect on metabolic-related disease outcomes, pulmonary disease, or neurocognitive function. HIV causes immune impairment soon after acquisition of infection. ART reverses this harm at least partially. The biological nature of the immune impairment needs further elucidation, as well as mechanisms and clinical impact of innate immune activation. Based on the findings from TEMPRANO and START, and because ART lowers the risk of onward transmission, ART initiation should be offered to all persons following their diagnosis of HIV.

Abstract
Background The World Health Organization (WHO) in 2013 has revised its guidelines on antiretroviral therapy (ART) treatment for human immunodeficiency virus (HIV)-positive adults and further updated it in 2016. Based on the WHO recommendations, in May 2017, National AIDS Control Organisation, India recommended initiation of ART treatment for all people living with HIV, regardless of CD4 count, clinical stage, age, or population. This systematic review aims to assess the clinical effectiveness and cost implication of the new guidelines for India. Methods A systematic and comprehensive literature search on PubMed, OvidSP, Cochrane Library, and Google Scholar was carried out. Studies reporting either acquired immunodeficiency syndrome (AIDS) or mortality or both as outcome variables were selected. A meta-analysis of the available studies was carried out. The risk ratio was calculated to assess the reduction in AIDS or mortality or both. Cost-effectiveness analysis using health technology principles evaluating the lives saved in terms of incremental cost-effectiveness ratio and cost per quality-adjusted life years gained was carried out. Results Nine eligible studies were included for the meta-analysis. For India, the pooled relative risk of AIDS or mortality or both being 0.84 (95% confidence interval [CI], 0.76-0.92) and 0.78 (95% CI, 0.68-0.89) for ART initiation at CD4 count of ≤350 vs CD4 count of ≤500 and at CD4 count of ≤500 vs CD4 count > 500 cells/mm3, respectively. The incremental cost for per additional life saved is US$ 2592 and US$ 2357 for ART initiation at ≤500 and > 500 CD4 count, respectively. Conclusion The adoption of the new WHO guidelines is beneficial with substantial reduction in AIDS or mortality or both. This study suggests that adopting new WHO guidelines is cost-effective for India.

Abstract
CONTEXT Screening for HIV infection in medical settings remains suboptimal. OBJECTIVE To examine the real-world effectiveness of an electronic clinician alert on the same-day HIV testing rate and early diagnosis in high-risk populations. DESIGN We identified Kaiser Permanente Southern California Health Plan members aged 14 years or older who received tests for sexually transmitted infections. MAIN OUTCOME MEASURES Encounter-based same-day HIV testing rate, positive test result rate, and CD4+ cell count and HIV viral load at diagnosis. RESULTS We identified 1,800,948 patients who made 2,326,701 health care encounters eligible for HIV testing before implementation (January 1, 2008 - June 30, 2012) and 1,362,479 eligible encounters after implementation (January 1, 2013 - June 30, 2015). The same-day HIV testing rate increased from 36.7% to 44.1% (standardized mean difference = 0.15, significant difference). The alert was associated with a moderate difference and statistically significant increase in the HIV testing rate (adjusted odds ratio = 1.17, 95% confidence interval = 1.16-1.18). The positive test result rate increased from 0.02% to 0.04% (p < 0.001). During the postimplementation period, fewer HIV-infected patients had a CD4+ cell count below 200 and/or an HIV viral load of 10,000 copies/mL or higher at diagnosis. CONCLUSION Implementation of a targeted electronic alert embedded in the electronic medical record improved same-day HIV screening rate and positive test result rates among patients receiving tests for sexually transmitted infections in a large health organization. This intervention has potential for facilitating frequent screening and early identification of HIV infection in high-risk populations.

Abstract
The management of patients with human immunodeficiency virus (HIV) can be a complicated specialty within itself, made even more complex when there are so many unanswered questions regarding the care of critically ill patients with HIV. The lack of consensus on the use of antiretroviral medications in the critically ill patient population has contributed to an ongoing clinical debate among intensivists. This review focuses on the pharmacological complications of antiretroviral therapy (ART) in the intensive care setting, specifically the initiation of ART in patients newly diagnosed with HIV, immune reconstitution inflammatory syndrome (IRIS), continuation of ART in those who were on a complete regimen prior to intensive care unit admission, barriers of drug delivery alternatives, and drug-drug interactions.

Abstract
Early antiretroviral therapy (ART) initiation is a recommended public health approach for the prevention of HIV-1 transmission. In this cohort study, we included 13132 serodiscordant couples. ART was initiated for patients with CD4+ T cell counts less than 200 cells/uL, 350 cells/uL, and 500 cells/uL respectively. This divided the ART treated couples into three groups. Univariate and multivariate intention-to-treat analyses were performed to examine the association between the study groups. Early-ART initiation was associated with a 45% lower risk of partner infection than was late-ART initiation (AHR 0.55, 95% CI, 0.37–0.81). Mid-ART initiation was associated with a 39% lower risk of partner infection than was late-ART initiation (AHR 0.61, 95% CI, 0.48–0.78). However, the risk reduction between the early and mid-ART groups was not significant. Drug compliance (AHR 1.55, 95% CI 1.03–2.35) and increased baseline viral load (AHR 1.41, 95% CI 1.33–1.51) were associated with an increased risk of infections among partners in the treatment. Prevention of HIV transmission as a result of early ART initiation was feasible on national and regional scales; however, many factors, such as the motivation to commence ART, adherence, and attrition, may affect the impact of this strategy in programmatic settings.

Abstract
OBJECTIVE We estimated and compared the risk of clinically identified acquired drug resistance under immediate initiation [the currently recommended antiretroviral therapy (ART) initiation strategy], initiation with CD4 cell count less than 500 cells/μl and initiation with CD4 cell count less than 350 cells/μl. DESIGN Cohort study based on routinely collected data from the HIV-CAUSAL collaboration. METHODS For each individual, baseline was the earliest time when all eligibility criteria (ART-naive, AIDS free, and others) were met after 1999. Acquired drug resistance was defined using the Stanford classification as resistance to any antiretroviral drug that was clinically identified at least 6 months after ART initiation. We used the parametric g-formula to adjust for time-varying (CD4 cell count, HIV RNA, AIDS, ART regimen, and drug resistance testing) and baseline (calendar period, mode of acquisition, sex, age, geographical origin, ethnicity and cohort) characteristics. RESULTS In 50 981 eligible individuals, 10% had CD4 cell count more than 500 cells/μl at baseline, and 63% initiated ART during follow-up. Of 2672 tests for acquired drug resistance, 794 found resistance. The estimated 7-year risk (95% confidence interval) of acquired drug resistance was 3.2% (2.8,3.5) for immediate initiation, 3.1% (2.7,3.3) for initiation with CD4 cell count less than 500 cells/μl, and 2.8% (2.5,3.0) for initiation with CD4 cell count less than 350 cells/μl. In analyses restricted to individuals with baseline in 2005-2015, the corresponding estimates were 1.9% (1.8, 2.5), 1.9% (1.7, 2.4), and 1.8% (1.7, 2.2). CONCLUSION Our findings suggest that the risk of acquired drug resistance is very low, especially in recent calendar periods, and that immediate ART initiation only slightly increases the risk. It is unlikely that drug resistance will jeopardize the proven benefits of immediate ART initiation.

Abstract
The chief concerns for antiretroviral therapy (ART) programs considering removal of CD4+ cell count thresholds for treatment are the increased incidence of ART-related adverse events. A nationwide observational cohort study was conducted among patients who initiated ART in 2012. We divided the eligible patients into three groups: an early ART group with a baseline CD4+ cell count of 500 cells/μL or greater, a standard ART group with a baseline CD4+ cell count between 350 and 499 cells/μL, and a late ART group with a baseline CD4+ cell count between 200 and 349 cells/μL. These patients were followed up to December 31, 2014 and observed for three outcomes: virological failure, treatment nonretention, or time to death. Patients who met the eligibility criteria numbered at 26,752. Out of all study participants, 20,827 participants were in late ART group, 4336 were in standard ART group, and 1589 were in early ART group. Patients in late ART group were more likely to become virally suppressed 12 and 24 months after treatment initiation than patients in early ART group [adjusted odds ratio (aOR) 0.81; 95% CI, 0.69-0.95 and aOR, 0.78; 95% CI, 0.65-0.94]. Treatment nonretention was also less likely to occur among patients in late ART group than early ART group 12 months after treatment initiation (aOR, 0.85; 95% CI, 0.75-0.96). Compared with early ART group, neither standard ART group nor late ART group had a statistically significant difference in the time-to-death analysis. Late ART initiates were more likely to be virally suppressed and retained on treatment than early ART initiates. The importance of treatment retention and adherence should be emphasized for high CD4+ patients newly initiated to ART therapy through education and counseling programs.

Abstract
PURPOSE OF REVIEW The purpose is to describe and understand the sociodemographic determinants of survival in people living with HIV within high-income countries in the context of the current recommendation of universal antiretroviral therapy for all HIV-infected persons, irrespective of their CD4 cell count. RECENT FINDINGS Survival rates in people living with HIV have experienced remarkable increases in the last decade because of more efficacious and well tolerated treatments. Still, these improvements are unevenly distributed between regions across the world as well as within regions. HIV outcomes are heavily influenced by what are known as the 'social determinants' of health which have traditionally encompassed the gender, race/ethnicity, and socioeconomic axes. The evidence that these social determinants are now more important than before (more and earlier interventions are now available), has become stronger in the last 2 years. SUMMARY Because antiretroviral therapy is now recommended for all HIV-infected persons, sociodemographic factors limiting access to testing, treatment, and retention in care will undoubtedly jeopardize the UNAIDS aspirational objective to end AIDS by 2030. Innovative interventions targeting individuals with social vulnerability are urgently needed to ensure that social inequalities do not continue to be linked with higher mortality.

Abstract
Supplemental Digital Content is Available in the Text. Background: Viremia copy-years (VCY), a time-updated measure of cumulative HIV exposure, predicts AIDS/death; although its utility in deciding when to start combination antiretroviral therapy (cART) remains unclear. We aimed to assess the impact of initiating versus deferring cART on risk of AIDS/death by levels of VCY both independent of and within CD4 cell count strata ≥500 cells per cubic millimeter. Methods: Using Concerted Action on Seroconversion to AIDS and Death in Europe (CASCADE) data, we created a series of nested “trials” corresponding to consecutive months for individuals ≥16 years at seroconversion after 1995 who were cART-naive and AIDS-free. Pooling across all trials, time to AIDS/death by CD4, and VCY strata was compared in those initiating vs. deferring cART using Cox models adjusted for: country, sex, risk group, seroconversion year, age, time since last HIV-RNA, and current CD4, VCY, HIV-RNA, and mean number of previous CD4/HIV-RNA measurements/year. Results: Of 9353 individuals, 5312 (57%) initiated cART and 486 (5%) acquired AIDS/died. Pooling CD4 strata, risk of AIDS/death associated with initiating vs. deferring cART reduced as VCY increased. In patients with high CD4 cell counts, ≥500 cells per cubic millimeter, there was a trend for a greater reduction for those initiating vs. deferring with increasing VCY (P = 0.09), with the largest benefit in the VCY ≥100,000 copy-years/mL group [hazard ratio (95% CI) = 0.41 (0.19 to 0.87)]. Conclusions: For individuals with CD4 ≥500 cells per cubic millimeter, limiting the cumulative HIV burden to <100,000 copy-years/mL through cART may reduce the risk of AIDS/death.

Abstract
PURPOSE The most important articles on infectious diseases (ID) pharmacotherapy published in the peer-reviewed literature in 2015, as nominated and selected by panels of pharmacists and others with ID expertise, are summarized. SUMMARY Members of the Houston Infectious Diseases Network were asked to nominate articles published in prominent peer-reviewed journals in 2015 that were thought to have a major impact in the field of ID pharmacotherapy. A list of 55 nominated articles on general ID-related topics and 10 articles specifically related to human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome (AIDS) was compiled. In a national online survey, members of the Society of Infectious Diseases Pharmacists (SIDP) were asked to select from the list 10 general ID articles believed to have made a significant contribution to the field of ID pharmacotherapy and 1 article contributing to HIV/AIDS pharmacotherapy. Of the 361 SIDP members surveyed, 153 (42%) and 76 (21%) participated in the selection of general ID-related articles and HIV/AIDS-related articles, respectively. The 11 highest-ranked publications (10 general ID-related articles and 1 HIV/AIDS-related article) are summarized here. CONCLUSION With the growing number of significant ID-related publications each year, it can be challenging to stay current with the literature. This review of important ID pharmacotherapy publications in 2015 may be helpful in identifying key articles and lessening this burden.

Abstract
BACKGROUND Standard-of-care antiretroviral therapy (ART) for human immunodeficiency virus (HIV) infection uses a combination of drugs, until now considered essential to minimise treatment failure and development of drug resistance. Protease inhibitors (PIs) are potent with a high genetic barrier to resistance and have the potential for use as monotherapy after viral load (VL) suppression achieved on combination therapy. However, longer-term resistance and toxicity risks are uncertain. OBJECTIVE To compare the effectiveness, toxicity profile and cost-effectiveness of PI monotherapy with those of standard-of-care triple therapy in a pragmatic long-term clinical trial. DESIGN Open-label, parallel-group, randomised controlled trial. SETTING Forty-three HIV clinical centres in the UK NHS. PARTICIPANTS HIV-positive adults taking standard combination ART with a suppressed VL for ≥ 6 months. INTERVENTIONS Patients were randomised to maintain ongoing triple therapy (OT) or switch to a strategy of physician-selected ritonavir-boosted PI monotherapy (PI-mono), with prompt return to combination therapy in the event of VL rebound. MAIN OUTCOME MEASURES The primary outcome was reduction of future drug options, defined as new intermediate-/high-level resistance to one or more drugs to which the patient's virus was considered to be sensitive at trial entry (non-inferiority comparison, 10% margin). Secondary outcomes included confirmed virological rebound, serious drug- or disease-related complications, total grade 3 or 4 adverse events (AEs), neurocognitive function change, cluster of differentiation 4 (CD4) cell count change, change in health-related quality of life, cardiovascular risk change, health-care costs and health economic analysis. RESULTS In total, 587 participants were randomised (77% male, 68% white) to OT (n = 291) or PI-mono (n = 296) and followed for a median of 44 months, of whom 2.7% withdrew/were lost to follow-up. One or more episodes of confirmed VL rebound were observed in eight patients (Kaplan-Meier estimate 3.2%) in the OT group and 95 patients (35.0%) in the PI-mono group [absolute risk difference 31.8%, 95% confidence interval (CI) 24.6% to 39.0%; p < 0.001]. PI-mono patients who changed to ART after VL rebound all resuppressed (median 3.5 weeks). The proportions with loss of a future drug option at 3 years were 0.7% in the OT group and 2.1% in the PI-mono group (difference 1.4%, (95% CI -0.4% to 3.4%); non-inferiority demonstrated). There were no significant differences in serious disease complications between groups or in the frequency of grade 3 or 4 clinical AEs (16.8% OT group vs. 22% PI-mono group; absolute risk difference 5.1%, 95% CI -1.3% to 11.5%; p = 0.12). Overall, the PI-mono strategy was shown to be cost-effective compared with OT under most scenarios explored. PI-mono was cost saving because of the large savings in ART drug costs while being no less effective in terms of quality-adjusted life-years in the within-trial analysis and only marginally less effective when extrapolated to lifetime outcomes. CONCLUSIONS PI monotherapy, with prompt reintroduction of combination therapy for VL rebound, was non-inferior to combination therapy in preserving future treatment options and is an acceptable and cost-effective alternative for long-term management of HIV infection.

Abstract
BACKGROUND In the current antiretroviral (ART) era, the evolution of HIV guidelines and emergence of new ART agents might be expected to impact the times to ART initiation and HIV virologic suppression. We sought to determine if times to AI and virologic suppression decreased and if disparities exist by age, race/ethnicity, and HIV risk. METHODS We performed a retrospective cohort study of data from 12 sites of the HIV Research Network, a consortium of US clinics caring for HIV-infected patients. HIV-infected adults (≥18 year old) newly presenting for care between 2003 and 2013 were included in this study. Times to AI and virologic suppression were defined as time from enrollment to AI and HIV RNA <400 copies per milliliter, respectively. We conducted time-to-event analyses using competing risk regression in the HIV Research Network cohort from 2003 to 2012 in 2-year intervals, with follow-up through 2013. RESULTS Among 15,272 participants, 76.9% were male, 48.4% black, and 10.9% were injection drug use with median age of 38 years (interquartile range: 29-46 years). The adjusted subdistribution hazards ratios (SHRs) for AI and virologic suppression each increased for years 2007-2008 [SHR 1.23 (1.16-1.30), and SHR 1.25 (1.17-1.34), respectively], 2009-2010 [1.55 (1.46-1.64), and 1.54 (1.43-1.65), respectively], and 2011-2012 [1.94 (1.83-2.07), and 1.73 (1.61-1.86), respectively] compared with 2003-2004. Blacks had a lower probability of AI than whites and Hispanics. CONCLUSIONS Since 2007, times from enrollment to AI and virologic suppression have decreased significantly compared with 2003-2004, but persisting disparities should be addressed.

Abstract
Optimal timing of initiating antiretroviral therapy has been a controversial topic in HIV research. Two highly publicized studies applied different analytical approaches, a dynamic marginal structural model and a multiple imputation method, to different observational databases and came up with different conclusions. Discrepancies between the two studies' results could be due to differences between patient populations, fundamental differences between statistical methods, or differences between implementation details. For example, the two studies adjusted for different covariates, compared different thresholds, and had different criteria for qualifying measurements. If both analytical approaches were applied to the same cohort holding technical details constant, would their results be similar? In this study, we applied both statistical approaches using observational data from 12,708 HIV-infected persons throughout the USA. We held technical details constant between the two methods and then repeated analyses varying technical details to understand what impact they had on findings. We also present results applying both approaches to simulated data. Results were similar, although not identical, when technical details were held constant between the two statistical methods. Confidence intervals for the dynamic marginal structural model tended to be wider than those from the imputation approach, although this may have been due in part to additional external data used in the imputation analysis. We also consider differences in the estimands, required data, and assumptions of the two statistical methods. Our study provides insights into assessing optimal dynamic treatment regimes in the context of starting antiretroviral therapy and in more general settings. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
The condylomata acuminata is a benign epithelial neoplasm induced by papillomavirus, and it is characterized by the proliferation of stratified squamous epithelial tissue that affects the anogenital and oral mucosa. It is considered to be a sexually transmitted disease and has a higher prevalence in individuals infected with human immunodeficiency virus. Various therapies have been used for the removal of lesions, such as cryotherapy, surgical laser and surgical excision, which are painful and scarring. These techniques, however, do not eliminate the virus and relapses are common shortly after treatment. The use of immunomodulators has been proposed to be an alternative treatment, as imidazolquinoline has been shown to be effective in the treatment of lesions in the anogenital region. However, its use in the oral cavity has been the subject of few reports in the literature. Thus, the objective of this study is to describe a case of warts in the labial mucosa of an HIV positive patient using imidazolquinoline 5%.

Abstract
This chapter reviews the neurologic complications of medications administered in the hospital setting, by class, introducing both common and less common side effects. Detail is devoted to the interaction between pain, analgesia, sedation, and their residual consequences. Antimicrobials are given in nearly every hospital setting, and we review their capacity to produce neurologic sequelae with special devotion to cefepime and the antiviral treatment of human immunodeficiency virus. The management of hemorrhagic stroke has become more complex with the introduction of novel oral anticoagulants, and we provide an update on what is known about reversal of the new oral anticoagulants. Both central and peripheral nervous system complications of immunosuppressants and chemotherapies are reviewed. Because diagnosis is generally based on clinical acumen, alone, neurotoxic syndromes resulting from psychotropic medications may be easily overlooked until severe dysautonomia develops. We include a practical approach to the diagnosis of serotonin syndrome and neuroleptic malignant syndrome.

Abstract
BACKGROUND Disparities in combined antiretroviral therapy (cART) outcomes have been consistently reported among people living with HIV (PLWHIV). The present study aims at investigating the mechanisms underlying those disparities among PLWHIV in France. METHODS We used data from the Vespa2 survey, a large national cross-sectional survey, representative of HIV-infected people followed at hospitals in 2011. Among participants diagnosed ≥1996, HIV treatment-naive at the time of cART initiation and on cART for at least 12 months, the frequency of sustained virological suppression (SVS; undetectable viral load [<50 copies/ml] for at least 6 months) at the time of the survey, was assessed and its social determinants were measured through logistic regression, accounting for clinical and biological determinants of response to cART. RESULTS Among 1,246 participants, 77.7% had achieved SVS. SVS was less frequent among those unemployed (0.6 [range 0.3-1.0]) and those with the lowest level of education (0.4 [range 0.2-0.9]). The late presenters, diagnosed at a CD4+ T-cell count <200/mm3 (0.5 [range 0.3-0.9]) and the late starters, diagnosed at a CD4+ T-cell count >200 but initiating cART at CD4+ T-cell count <200 (0.3 [range 0.1-0.8]) were less likely than the ideal starters (≥350 CD4+ T-cells/mm3 at cART initiation) to achieve SVS, as were those who reported suboptimal adherence versus those reporting optimal adherence (0.4 [range 0.2-0.7]). In bivariate analyses, material deprivation, discrimination and a weak social network were also associated with a poorer treatment response. CONCLUSIONS Structural social factors remain strong determinants of treatment response and should be addressed in a broad approach of care, but wider political issues should also be investigated.

Abstract
This article analyses research exploring medication adherence, help-seeking behaviour, screening and behaviour change to argue that all interventions have the potential for both benefit and harm. Accordingly, health psychology may have inadvertently contributed to psychological harms (e.g. lead times, anxiety, risk compensation and rebound effects); medical harms (e.g. medication side effects, unnecessary procedures) and social harms (e.g. financial costs, increased consultations rates). Such harms may result from medicalisation or pharmaceuticalisation. Or, they may reflect the ways in which we manage probabilities and an optimistic bias that emphasises benefit over cost.

Abstract
OBJECTIVES This study was conducted to clarify the rate of late diagnosis of HIV infection and to identify relationships between the reasons for HIV testing and a late diagnosis. METHODS This retrospective cohort study was conducted among HIV-positive patients at the Jikei University Hospital between 2001 and 2014. Patient characteristics from medical records, including age, sex, sexuality, the reason for HIV testing and the number of CD4-positive lymphocytes at HIV diagnosis, were assessed. RESULTS A total of 459 patients (men, n=437; 95.2%) were included in this study and the median age at HIV diagnosis was 36 years (range, 18-71 years). Late (CD4 cell count <350/mm3) and very late (CD4 cell count <200/mm3) diagnoses were observed in 61.4% (282/459) and 36.6% (168/459) of patients, respectively. The most common reason for HIV diagnosis was voluntary testing (38.6%, 177/459 patients), followed by AIDS-defining illness (18.3%, 84/459 patients). Multivariate analysis revealed a significant association of voluntary HIV testing with non-late and non-very-late diagnoses and there was a high proportion of AIDS-defining illness in the late and very late diagnosis groups compared with other groups. Men who have sex with men was a relative factor for non-late diagnosis, whereas nonspecific abnormal blood test results, such as hypergammaglobulinemia and thrombocytopenia, were risk factors for very late diagnosis. CONCLUSIONS Voluntary HIV testing should be encouraged and physicians should screen all patients who have symptoms or signs and particularly hypergammaglobulinemia and thrombocytopenia, that may nonspecifically indicate HIV infection.

Abstract
OBJECTIVE There is limited research investigating the possible mechanisms of how starting combination antiretroviral therapy (cART) at a higher CD4 cell count decreases mortality. This study investigated the association between initiating cART with short-term and long-term achievement of viral suppression; emergence of any drug resistance and of an AIDS-defining illness (ADI); long-term treatment adherence; and all-cause mortality. METHODS This retrospective cohort study included 4120 naive patients who initiated cART between 2000 and 2012. Patients were followed until 2013, death or until the last contact date (varied by outcome). The main exposure was the interaction between period of cART initiation (2000-2006 and 2007-2012) and CD4 cell count at cART initiation (<500 versus ≥500 cells/μl). We considered both baseline and longitudinal covariates. We fitted different multivariable models using cross-sectional and longitudinal statistical methods, depending on the outcome. RESULTS Patients who initiated cART with a CD4 cell count at least 500 cells/μl in 2007-2012 had an increased likelihood of achieving viral suppression at 9 months and of maintaining an adherence level of at least 95% over time, and the lowest probability of developing any resistance and an ADI during follow-up. These patients were not the ones with the highest likelihood of maintaining viral suppression over time, most likely due to viral load blips experienced during the follow-up. CONCLUSION The outcomes in this study likely play an important role in explaining the positive impact of early cART initiation on mortality. These results should alleviate some of the concerns clinicians may have when initiating cART in patients with high CD4s as recommended by current treatment guidelines.

Abstract
BACKGROUND Data from randomized trials are lacking on the benefits and risks of initiating antiretroviral therapy in patients with asymptomatic human immunodeficiency virus (HIV) infection who have a CD4+ count of more than 350 cells per cubic millimeter. METHODS We randomly assigned HIV-positive adults who had a CD4+ count of more than 500 cells per cubic millimeter to start antiretroviral therapy immediately (immediate-initiation group) or to defer it until the CD4+ count decreased to 350 cells per cubic millimeter or until the development of the acquired immunodeficiency syndrome (AIDS) or another condition that dictated the use of antiretroviral therapy (deferred-initiation group). The primary composite end point was any serious AIDS-related event, serious non-AIDS-related event, or death from any cause. RESULTS A total of 4685 patients were followed for a mean of 3.0 years. At study entry, the median HIV viral load was 12,759 copies per milliliter, and the median CD4+ count was 651 cells per cubic millimeter. On May 15, 2015, on the basis of an interim analysis, the data and safety monitoring board determined that the study question had been answered and recommended that patients in the deferred-initiation group be offered antiretroviral therapy. The primary end point occurred in 42 patients in the immediate-initiation group (1.8%; 0.60 events per 100 person-years), as compared with 96 patients in the deferred-initiation group (4.1%; 1.38 events per 100 person-years), for a hazard ratio of 0.43 (95% confidence interval [CI], 0.30 to 0.62; P<0.001). Hazard ratios for serious AIDS-related and serious non-AIDS-related events were 0.28 (95% CI, 0.15 to 0.50; P<0.001) and 0.61 (95% CI, 0.38 to 0.97; P=0.04), respectively. More than two thirds of the primary end points (68%) occurred in patients with a CD4+ count of more than 500 cells per cubic millimeter. The risks of a grade 4 event were similar in the two groups, as were the risks of unscheduled hospital admissions. CONCLUSIONS The initiation of antiretroviral therapy in HIV-positive adults with a CD4+ count of more than 500 cells per cubic millimeter provided net benefits over starting such therapy in patients after the CD4+ count had declined to 350 cells per cubic millimeter.

Abstract
BACKGROUND Recommendations have differed nationally and internationally with respect to the best time to start antiretroviral therapy (ART). We compared effectiveness of three strategies for initiation of ART in high-income countries for HIV-positive individuals who do not have AIDS: immediate initiation, initiation at a CD4 count less than 500 cells per μL, and initiation at a CD4 count less than 350 cells per μL. METHODS We used data from the HIV-CAUSAL Collaboration of cohort studies in Europe and the USA. We included 55,826 individuals aged 18 years or older who were diagnosed with HIV-1 infection between January, 2000, and September, 2013, had not started ART, did not have AIDS, and had CD4 count and HIV-RNA viral load measurements within 6 months of HIV diagnosis. We estimated relative risks of death and of death or AIDS-defining illness, mean survival time, the proportion of individuals in need of ART, and the proportion of individuals with HIV-RNA viral load less than 50 copies per mL, as would have been recorded under each ART initiation strategy after 7 years of HIV diagnosis. We used the parametric g-formula to adjust for baseline and time-varying confounders. FINDINGS Median CD4 count at diagnosis of HIV infection was 376 cells per μL (IQR 222-551). Compared with immediate initiation, the estimated relative risk of death was 1·02 (95% CI 1·01-1·02) when ART was started at a CD4 count less than 500 cells per μL, and 1·06 (1·04-1·08) with initiation at a CD4 count less than 350 cells per μL. Corresponding estimates for death or AIDS-defining illness were 1·06 (1·06-1·07) and 1·20 (1·17-1·23), respectively. Compared with immediate initiation, the mean survival time at 7 years with a strategy of initiation at a CD4 count less than 500 cells per μL was 2 days shorter (95% CI 1-2) and at a CD4 count less than 350 cells per μL was 5 days shorter (4-6). 7 years after diagnosis of HIV, 100%, 98·7% (95% CI 98·6-98·7), and 92·6% (92·2-92·9) of individuals would have been in need of ART with immediate initiation, initiation at a CD4 count less than 500 cells per μL, and initiation at a CD4 count less than 350 cells per μL, respectively. Corresponding proportions of individuals with HIV-RNA viral load less than 50 copies per mL at 7 years were 87·3% (87·3-88·6), 87·4% (87·4-88·6), and 83·8% (83·6-84·9). INTERPRETATION The benefits of immediate initiation of ART, such as prolonged survival and AIDS-free survival and increased virological suppression, were small in this high-income setting with relatively low CD4 count at HIV diagnosis. The estimated beneficial effect on AIDS is less than in recently reported randomised trials. Increasing rates of HIV testing might be as important as a policy of early initiation of ART.

Abstract
BACKGROUND The goal of targeted antiretroviral therapy initiation is to minimize disease progression among patients with human immunodeficiency virus while minimizing the therapeutic burden on these patients. We examine whether the effect of delaying therapy initiation from 500 cells/mm(3) to 350 or 200 cells/mm(3) is modified by age at entry into care. METHODS We used the parametric g-formula to compare 10-year mortality under 3 CD4 cell count thresholds for therapy initiation among 3532 patients who entered care at 1 of 8 sites in the United States between 1998 and 2013. Results are reported separately for patients 18 to 34, 35 to 44, and 45 to 65 years of age at study entry. RESULTS In the observed data, 10-year mortality was 13% (165 deaths). Mortality increased from 11% under therapy initiation at 500 cells/mm(3) to 12% at 350 cells/mm(3) (risk difference [RD]: 0.87; 95% confidence interval [CI]: .56, 2.17) and to 14% at 200 cells/mm(3) (RD: 2.71; 95% CI: 1.79, 5.38). The effect of delaying therapy became greater with age: RDs comparing the 350-cells/mm(3) threshold with the 500-cells/mm(3) threshold ranged from -0.03 (95% CI: -0.15, 1.76) for patients 18 to 34 years of age to 0.99 (95% CI: -.27, 1.98) for patients 35 to 44 and to 2.30 (95% CI: 1.29, 5.42) for patients 45 to 65. CONCLUSIONS Delaying therapy increased 10-year mortality in the full cohort. Subgroup analysis highlights that patients entering care at older ages may be more vulnerable to the consequences of delayed ART initiation than younger patients.

Abstract
New evidence has emerged regarding when to commence antiretroviral therapy (ART), optimal treatment regimens, management of HIV co-infection with opportunistic infections, and management of ART failure. The 2014 guidelines were developed by the collaborations of the Department of Disease Control, Ministry of Public Health (MOPH) and the Thai AIDS Society (TAS). One of the major changes in the guidelines included recommending to initiating ART irrespective of CD4 cell count. However, it is with an emphasis that commencing HAART at CD4 cell count above 500 cell/mm3 is for public health, in term of preventing HIV transmission and personal benefit. In tuberculosis co-infected patients with CD4 cell counts ≤50 cells/mm3 or with CD4 cell counts >50 cells/mm3 who have severe clinical disease, ART should be initiated within 2 weeks of starting tuberculosis treatment. The preferred initial ART regimen in treatment naïve patients is efavirenz combined with tenofovir and emtricitabine or lamivudine. Plasma HIV viral load assessment should be done twice a year until achieving undetectable results; and will then be monitored once a year. CD4 cell count should be monitored every 6 months until CD4 cell count ≥350 cells/mm3 and with plasma HIV viral load <50 copies/mL; then it should be monitored once a year afterward. HIV drug resistance genotypic test is indicated when plasma HIV viral load >1,000 copies/mL while on ART. Ritonavir-boosted lopinavir or atazanavir in combination with optimized two nucleoside-analogue reverse transcriptase inhibitors is recommended after initial ART regimen failure. Long-term ART-related safety monitoring has also been included in the guidelines.

Abstract
Determining when to start antiretroviral treatment (ART) is vitally important for people living with HIV. Yet the optimal point at which to start to maximize clinical benefit remains unknown. In the absence of randomized studies, current guidelines rely on conflicting observational data and expert opinion, and consequently diverge on this point. In the USA, ART is recommended irrespective of CD4 cell count. The World Health Organization now recommends starting ART at a CD4 cell count of 500 cells/μL, while the threshold for the UK and South Africa remains at 350 cells/μL. The Strategic Timing of AntiRetroviral Treatment (START) study, one of the largest clinical trials on the treatment of HIV infection, will answer this question. START compares two treatment strategies: immediate treatment at a CD4 cell count of 500 cells/μL or higher versus deferring treatment until the CD4 cell count decreases to 350 cells/μL or until AIDS develops. START includes seven substudies, five of which will clarify the relative contributions of HIV and ART in common comorbidities. START is fully enrolled and expected to be completed in 2016. HIV advocates support the study's design and have been involved from inception to enrolment. The trial will produce rigorous data on the benefits and risks of earlier treatment. It will inform policy and treatment advocacy globally, benefitting the health of HIV-positive people.

Abstract
Outpatient care for people living with HIV is delivered in diverse settings. Differences in setting may impact HIV outcomes. We evaluated HIV-infected adults in care at Ryan White-funded clinics in Philadelphia, PA, between 2008 and 2011 to determine how setting of care (hospital versus community-based) influenced HIV outcomes. Clinics were categorized as hospital-based if they were located onsite at a hospital. The composite outcome was completion of the final three steps of the HIV care continuum: (1) retention in care; (2) use of antiretroviral therapy (ART); and (3) viral suppression. Mixed-effects logistic regression, accounting for patient and clinic factors, examined the relationship between care setting and the outcome. In total, 12,637 patients, contributing 32,515 patient-years, received care at 25 clinics (12 hospital-based). Women, non-Hispanic blacks, those with private insurance, and individuals with higher household incomes more commonly attended hospital-based clinics (p<0.05). Of the 12,962 patient-years (40%) during which patients attended community-based clinics, 59% met the outcome. Similarly, 59% of the 19,553 patient-years (60%) in which patients attended hospital-based clinics met the outcome. Adjusting for patient and clinic factors, setting was not associated with the outcome (adjusted odds ratio=1.24, 95% CI=0.84-1.84). In summary, demographics differ among patients visiting hospital and community-based clinics. Completion of the final three steps of the HIV care continuum did not vary between hospital and community-based clinics, which may reflect advances in HIV therapy and the wide availability of HIV care resources.

Abstract
INTRODUCTION In Spain, HIV treatment guidelines are well known and generally followed. However, in some patients there are no plans to initiate ART despite having treatment indications. The current barriers to ART initiation are presented. METHODS A cross-sectional survey including every HIV infected patient in care in 19 hospitals across Spain in 2012, with ≥1 indication to start ART according to 2011 national treatment guidelines, who had not been scheduled for ART initiation. Reasons for deferring treatment were categorized as follows (non-exclusive categories): a) The physician thinks the indication is not absolute and prefers to defer it; b) The patient does not want to start it; c) The physician thinks ART must be started, but there is some limitation to starting it, and d) The patient has undetectable viral load in absence of ART. RESULTS A total of 256 patients, out of 784 originally planned, were included. The large majority (84%) were male, median age 39 years, 57% MSM, 24% heterosexuals, and 16% IDUs. Median time since HIV diagnosis was 3 years, median CD4 count, 501 cells/mm3, median viral load 4.4 log copies/ml. Main ART indications were: CD4 count <500 cells/mm(3), 48%; having an uninfected sexual partner, 28%, and hepatitis C coinfection, 23%. Barriers due to, the physician, 55%; the patient, 28%; other limitations, 23%; and undetectable viral load, 6%. CONCLUSIONS The majority of subjects with ART indication were on it. The most frequent barriers among those who did not receive it were physician-related, suggesting that the relevance of the conditions that indicate ART may need reinforcing.

Abstract
IMPORTANCE In individuals with human immunodeficiency virus 1 (HIV-1) infection who are receiving antiretroviral therapy (ART), factors that promote full immune recovery are not well characterized. OBJECTIVE To investigate the influence of the timing of ART relative to HIV-1 infection on normalization of CD4+ T-cell counts, AIDS risk, and immune function. DESIGN, SETTING, AND PARTICIPANTS Participants in the observational US Military HIV Natural History Study with documented estimated dates of seroconversion (EDS) who achieved virologic suppression with ART were evaluated. Markers indicative of immune activation, dysfunction, and responsiveness were determined. Responses to hepatitis B virus (HBV) vaccine, an indicator of in vivo immune function, were also assessed. The timing of ART was indexed to the EDS and/or entry into the cohort. The CD4+ counts in HIV-1-uninfected populations were surveyed. MAIN OUTCOMES AND MEASURES Normalization of CD4+ counts to 900 cells/μL or higher, AIDS development, HBV vaccine response, as well as T-cell activation, dysfunction, and responsiveness. RESULTS The median CD4+ count in HIV-1-uninfected populations was approximately 900 cells/μL. Among 1119 HIV-1-infected participants, CD4+ normalization was achieved in 38.4% vs 28.3% of those initiating ART within 12 months vs after 12 months from the EDS (P = .001). Incrementally higher CD4+ recovery (<500, 500-899, and ≥900 cells/μL) was associated with stepwise decreases in AIDS risk and reversion of markers of immune activation, dysfunction, and responsiveness to levels approximating those found in HIV-1-uninfected persons. Participants with CD4+ counts of 500 cells/μL or higher at study entry (adjusted odds ratio [aOR], 2.00; 95% CI, 1.51-2.64; P < .001) or ART initiation (aOR, 4.08; 95% CI, 3.14-5.30; P < .001) had significantly increased CD4+ normalization rates compared with other participants. However, even among individuals with a CD4+ count of 500 cells/μL or higher at both study entry and before ART, the odds of CD4+ normalization were 80% lower in those initiating ART after 12 months from the EDS and study entry (aOR, 0.20; 95% CI, 0.07-0.53; P = 001). Initiation of ART within 12 months of EDS vs later was associated with a significantly lower risk of AIDS (7.8% vs 15.3%; P = .002), reduced T-cell activation (percent CD4+HLA-DR+ effector memory T cells, 12.0% vs 15.6%; P = .03), and increased responsiveness to HBV vaccine (67.9% vs 50.9%; P = .07). CONCLUSIONS AND RELEVANCE Deferral of ART beyond 12 months of the EDS diminishes the likelihood of restoring immunologic health in HIV-1-infected individuals.

Abstract
INTRODUCTION Clinicians often do not have the time and possibilities to read all scientific evidence necessary to maintain high quality patient care. They rely on guidelines made by experts to help them in their daily work. METHODS We compared the 2012 recommendations and the arguments of the IAS-USA Panel with the data referenced and presented with the original data of the studies. Special topic was the timing of antiretroviral therapy. Only studies included in the guideline text were analyzed. RESULTS There is a large discrepancy between the data and the recommendations concerning early antiviral therapy. The studies are either not designed to answer this question or the data is not sufficient to support the arguments. The authors highlight benefits without mention of side effects or other problems. Neither in transmission rates, nor mortality, AIDS events, co-morbidities (hepatitis B and C excluded) or decreasing the risk of malignancy, the data presented support early therapy. CONCLUSIONS A large discrepancy between the underlining data and the recommendation made by the IAS-USA Panel exists concerning early antiviral therapy.

Abstract
BACKGROUND Quantifying pediatric immunologic recovery by highly active antiretroviral therapy (HAART) initiation at different CD4 percentage (CD4%) and age thresholds may inform decisions about timing of treatment initiation. METHODS HIV-1-infected, HAART-naive children in Europe and the Americas were followed from 2002 through 2009 in PENPACT-1. Data from 162 vertically infected children, with at least World Health Organization "mild" immunosuppression and CD4% <10th percentile, were analyzed for improvement to a normal CD4% (≥10th percentile) within 4 years after HAART initiation. Data from 209 vertically infected children, regardless of immune status, were analyzed for CD4% outcomes at 4 years and viral failure within 4 years. RESULTS Seventy-two percent of baseline immunosuppressed children recovered to normal within 4 years. Compared with "severe" immunosuppression, more children with "mild" immunosuppression (difference 36%, 95% confidence interval [CI]: 22% to 49%) or "advanced" immunosuppression (difference 20.8%, 95% CI: 5.8% to 35.9%) recovered a normal CD4%. For each 5-year increase in baseline age, the proportion of children achieving a normal CD4% declined by 19% (95% CI: 11% to 27%). Combining baseline CD4% and age effects resulted in >90% recovery when initiating HAART with "mild" immunosuppression at any age or "advanced" immunosuppression at age <3 years. Baseline CD4% effects became greater with increasing age (P = .02). At 4 years, most immunologic benefits were still significant but diminished. Viral failure was highest in infancy (56%) and adolescence (63%). CONCLUSIONS Initiating HAART at higher CD4% and younger ages maximizes potential for immunologic recovery. Guidelines should weigh immunologic benefits against long-term risks.

BACKGROUND Describing the undiagnosed HIV-infected population is essential for guiding HIV screening policy, implementing interventions, and resource planning. METHODS We used French national HIV surveillance data and a back-calculation approach to estimate the number of undiagnosed HIV-infected individuals in France and the distribution of time since HIV infection among undiagnosed individuals. We also used data on CD4⁺ cell count decline to assess the CD4⁺ cell count distribution among undiagnosed individuals. RESULTS We estimated that 29,000 [95% confidence interval (CI): 24,200-33,900] individuals were living with undiagnosed HIV infection at the end of 2010. Of these, 28.7% (95% CI: 27.1-30.4) were infected less than a year ago, 16.4% (95% CI: 15.0-17.8) more than 5 years ago, and 59.6% (95% CI: 59.2-59.8) were eligible for antiretroviral treatment (CD4⁺ cell count less than 500 cells/μl) according to the 2010 French guidelines. Men represented 70.0% of the undiagnosed HIV-infected individuals and had lower CD4⁺ cell counts than women. The numbers of undiagnosed infections in MSM, non-French national heterosexuals, and French national heterosexuals were similar (9200, 9300, 10,000, respectively). However, because of differences in group size, undiagnosed HIV prevalence varied significantly between these groups (2.95, 0.36, 0.03%, respectively; P less than 0.001). CONCLUSION Our findings suggest that many undiagnosed HIV-infected individuals were eligible for treatment and, thus, lack of HIV diagnosis is a lost chance for them; many more heterosexuals than MSM will need to be tested to find those undiagnosed; and universal screening of men may be cost-effective, especially in the areas most affected by the epidemic, such as the Paris region.

Abstract
PURPOSE OF REVIEW When should people with HIV start treatment? This question is widely debated. The recent momentum to initiate treatment at a CD4 cell count above 350 cells/mm3 is driven by the potential population benefits of antiretroviral treatment reducing infectiousness together with operational concerns. These are important. However, we focus on the clinical benefits and risks for the person taking treatment, and how this may vary depending on the background health setting. RECENT FINDINGS We refer to the recent guideline changes and the limited evidence on which they are based. Many studies that have informed guideline changes reference plausible benefits, but have limited follow-up and are not designed to assess the potential risks. We note historical examples to show that expert opinion in the absence of data warrants caution. SUMMARY Results from well powered studies designed to look at the question of when to start treatment are essential for quantifying the benefits and risks of earlier treatment. Meanwhile, the decision of when to start must be taken by the HIV-positive person in consultation with their health worker based on accurate information. That choice will vary depending on a person's individual health, their reason to want to treat and the resources of the health-care facility.

Clinical course and quality of care in ART-naïve patients newly presenting in a HIV outpatient clinic. Infection 2014; 42:849-57. [PMID: 24965613 DOI: 10.1007/s15010-014-0646-9] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2014] [Accepted: 06/09/2014] [Indexed: 12/19/2022]
Abstract
OBJECTIVES Little data exist about the quality of care for HIV-infected subjects in Germany. We investigated the clinical course of HIV-infected subjects newly presenting in our HIV outpatient clinic. METHODS Antiretroviral therapy (ART)-naïve HIV-infected subjects presenting between 2007 and 2008 were followed until June 2012. Clinical data and laboratory parameters were collected prospectively and analysed retrospectively. RESULTS From 281 subjects included, 34 patients (12%) were lost to follow-up. 247 subjects remained, and 171 patients were followed for 1,497 days [1,121/1,726] (all data: median [interquartile range]). ART was started in 199 patients (81%) 182 days [44/849] after HIV diagnosis, and all patients were treated according to European guidelines or within clinical trials. The CD4 cell count at first presentation was 320/µL [160/500] and declined to 210/µL [100/300] at ART start. 12 months thereafter, the CD4 cell count increased to 410/µL [230/545]. The HIV RNA was suppressed below 50 copies/mL after 108 days [63/173] in 182 patients (91%). Initial ART was changed in 71 patients (36%) after 281 days [99/718], in five patients (7%) due to virological failure, in 66 patients (93%) due to other reasons, e.g. side effects or patient's request. CONCLUSION Two-thirds of the included patients were followed for more than 3 years, and ART was initiated in 81% of the patients leading to complete virological suppression in most patients. Compliance of physicians with treatment guidelines was high. Late presentation with a severely compromised immune function remains a problem and impairs the otherwise good prognosis of HIV infection.

Abstract
OBJECTIVES We examined the association between adherence to drug-refill visits and virologic outcomes in a cohort of HIV-infected adults on combination antiretroviral therapy (cART) in North Central Nigeria. METHODS Retrospectively, 588 HIV-infected, cART-naive adults (aged ≥15 years), initiated on first-line ART between 2009 and 2010 at the Jos University Teaching Hospital, were evaluated. Association between adherence to drug-refill visits, virologic (viral load>1000 copies/mL), and immunologic failure was assessed using multivariable logistic regression. RESULTS After a median of 12 months on cART, 16% (n=94) and 10% (n=59) of patients had virologic and immunologic failures, respectively. In the final multivariable model, suboptimal adherence to drug-refill visits was a significant predictor of both virologic (adjusted odds ratio [AOR] 1.6; 95% confidence interval [CI]:1.2-2.3) and immunologic (AOR 1.92; 95% CI:1.06-3.49) failures. CONCLUSION Adherence to drug refill is a useful predictor of successful virologic control and could be utilized for routine monitoring of adherence to cART in our clinical setting.

Enferm Infecc Microbiol Clin 2014; 32:446.e1-42. [PMID: 24953253 DOI: 10.1016/j.eimc.2014.02.019] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2014] [Accepted: 02/18/2014] [Indexed: 02/01/2023]
Abstract
OBJECTIVE This consensus document is an update of combined antiretroviral therapy (cART) guidelines for HIV-1 infected adult patients. METHODS To formulate these recommendations a panel composed of members of the Grupo de Estudio de Sida and the Plan Nacional sobre el Sida reviewed the efficacy and safety advances in clinical trials, cohort and pharmacokinetic studies published in medical journals (PubMed and Embase) or presented in medical scientific meetings. Recommendations strength and the evidence in which they are supported are based on modified criteria of the Infectious Diseases Society of America. RESULTS In this update, antiretroviral therapy (ART) is recommended for all patients infected by type 1 human immunodeficiency virus (HIV-1). The strength and grade of the recommendation varies with the clinical circumstances: CDC stage B or C disease (A-I), asymptomatic patients (depending on the CD4+ T-lymphocyte count: <350cells/μL, A-I; 350-500 cells/μL, A-II, and >500 cells/μL, B-III), comorbid conditions (HIV nephropathy, chronic hepatitis caused by HBV or HCV, age >55years, high cardiovascular risk, neurocognitive disorders, and cancer, A-II), and prevention of transmission of HIV (mother-to-child or heterosexual, A-I; men who have sex with men, A-III). The objective of ART is to achieve an undetectable plasma viral load. Initial ART should always comprise a combination of 3 drugs, including 2 nucleoside reverse transcriptase inhibitors and a third drug from a different family (non-nucleoside reverse transcriptase inhibitor, protease inhibitor, or integrase inhibitor). Some of the possible initial regimens have been considered alternatives. This update presents the causes and criteria for switching ART in patients with undetectable plasma viral load and in cases of virological failure where rescue ART should comprise 2 or 3 drugs that are fully active against the virus. An update is also provided for the specific criteria for ART in special situations (acute infection, HIV-2 infection, and pregnancy) and with comorbid conditions (tuberculosis or other opportunistic infections, kidney disease, liver disease, and cancer). CONCLUSIONS These new guidelines updates previous recommendations related to cART (when to begin and what drugs should be used), how to monitor and what to do in case of viral failure or drug adverse reactions. cART specific criteria in comorbid patients and special situations are equally updated.

French 2013 guidelines for antiretroviral therapy of HIV-1 infection in adults. J Int AIDS Soc 2014; 17:19034. [PMID: 24942364 PMCID: PMC4062879 DOI: 10.7448/ias.17.1.19034] [Citation(s) in RCA: 40] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2014] [Revised: 04/28/2014] [Accepted: 05/01/2014] [Indexed: 12/18/2022] Open
Abstract
Introduction These guidelines are part of the French Experts’ recommendations for the management of people living with HIV/AIDS, which were made public and submitted to the French health authorities in September 2013. The objective was to provide updated recommendations for antiretroviral treatment (ART) of HIV-positive adults. Guidelines included the following topics: when to start, what to start, specific situations for the choice of the first session of antiretroviral therapy, optimization of antiretroviral therapy after virologic suppression, and management of virologic failure. Methods Ten members of the French HIV 2013 expert group were responsible for guidelines on ART. They systematically reviewed the most recent literature. The chairman of the subgroup was responsible for drafting the guidelines, which were subsequently discussed within, and finalized by the whole expert group to obtain a consensus. Recommendations were graded for strength and level of evidence using predefined criteria. Economic considerations were part of the decision-making process for selecting preferred first-line options. Potential conflicts of interest were actively managed throughout the whole process. Results ART should be initiated in any HIV-positive person, whatever his/her CD4 T-cell count, even when >500/mm3. The level of evidence of the individual benefit of ART in terms of mortality or progression to AIDS increases with decreasing CD4 cell count. Preferred initial regimens include two nucleoside reverse transcriptase inhibitors (tenofovir/emtricitabine or abacavir/lamivudine) plus a non-nucleoside reverse transcriptase inhibitor (efavirenz or rilpivirine), or a ritonavir-boosted protease inhibitor (atazanavir or darunavir). Raltegravir, lopinavir/r, and nevirapine are recommended as alternative third agents, with specific indications and restrictions. Specific situations such as HIV infection in women, primary HIV infection, severe immune suppression with or without identified opportunistic infection, and person who injects drugs are addressed. Options for optimization of ART once virologic suppression is achieved are discussed. Evaluation and management of virologic failure are described, the aim of any intervention in such situation being to reduce plasma viral load to <50 copies/ml. Conclusion These guidelines recommend that any HIV-positive individual should be treated with ART. This recommendation was issued both for the patient’s own sake and for promoting treatment as prevention.
