Projected life expectancy of people with HIV according to timing of diagnosis

Implementation of an Immediate HIV Treatment Initiation Program in a Public/Academic Medical Center in the U.S. South: The Miami Test and Treat Rapid Response Program

Test and Rapid Response Treatment (TRRT) linkage programs have demonstrated improved HIV suppression rates. This paper describes the design and implementation of the Miami TRRT initiative and its clinical impact. Assisted by a dedicated care navigator, patients receiving a reactive HIV rapid test at the Florida Department of Health STD Clinic were offered same-day HIV care at the University of Miami/Jackson Memorial Medical Center Adult HIV Outpatient Clinic. Patient retention and labs were tracked for 12 months. Of the 2337 individuals tested, 46 had a reactive HIV test; 41 (89%) consented to participate. For the 36 patients in continued care for a year, 33 (91.7%) achieved virological suppression (< 200 copies/mL) within 70 days of their reactive HIV rapid test; at 12 months, 35 (97.2%) remained suppressed, and mean CD4 T cell counts increased from 452 ± 266 to 597 ± 322 cells/mm³. The Miami TRRT initiative demonstrated that immediate linkage to care is feasible and improves retention and suppression in a public/academic medical center in the U.S. South.

Rationale and design of a nurse-led intervention to extend the HIV treatment cascade for cardiovascular disease prevention trial (EXTRA-CVD)

Persons living with human immunodeficiency virus (PLHIV) are at increased risk of atherosclerotic cardiovascular disease (ASCVD). In spite of this, uptake of evidence-based clinical interventions for ASCVD risk reduction in the HIV clinic setting is sub-optimal. METHODS: EXTRA-CVD is a 12-month randomized clinical effectiveness trial that will assess the efficacy of a multi-component nurse-led intervention in reducing ASCVD risk among PLHIV. Three hundred high ASCVD risk PLHIV across three sites will be randomized 1:1 to usual care with generic prevention education or the study intervention. The study intervention will consist of four evidence-based components: (1) nurse-led care coordination, (2) nurse-managed medication protocols and adherence support (3) home BP monitoring, and (4) electronic health records support tools. The primary outcome will be change in systolic blood pressure and secondary outcome will be change in non-HDL cholesterol over the course of the intervention. Tertiary outcomes will include change in the proportion of participants in the following extended cascade categories: (1) appropriately diagnosed with hypertension and hyperlipidemia (2) appropriately managed; (3) at treatment goal (systolic blood pressure <130 mm Hg and non-HDL cholesterol < National Lipid Association targets). CONCLUSIONS: The EXTRA-CVD trial will provide evidence appraising the potential impact of nurse-led interventions in reducing ASCVD risk among PLHIV, an essential extension of the HIV care continuum beyond HIV viral suppression.

Relationships between cognition, function, and quality of life among HIV+ Canadian men

OBJECTIVE

To estimate the extent to which HIV-related variables, cognition, and other brain health factors interrelate with other HIV-associated symptoms to influence function, health perception, and QOL in older HIV+ men in Canada.

DESIGN

Cross-sectional structural equation modelling (SEM) of data from the inaugural visit to the Positive Brain Health Now Cohort.

SETTING

HIV clinics at 5 Canadian sites.

SUBJECTS

707 men, age ≥ 35 years, HIV+ for at least one year, without clinically diagnosed dementia.

MAIN OUTCOME MEASURES

Five latent and 21 observed variables from the World Health Organization's biopsychosocial model for functioning and disability and the Wilson-Cleary Model were analysed. SEM was used to link disease factors to symptoms, impairments, function, health perception, and QOL with a focus on cognition.

RESULTS

QOL was explained directly by depression, social role, health perception, social support, and quality of the environment. Measured cognitive performance had direct effects on activity/function and indirect effects on participation, HP and QOL, acting through self-reported cognitive difficulties and meaningful activities.

CONCLUSION

The biopsychosocial model showed good fit, with RMSEA < 0.05. This is the first time the full model has been tested in HIV. All of the domains included in the model are theoretically amenable to intervention and many have evidence-based interventions that could be harnessed to improve QOL.

The Effectiveness of Social Marketing Interventions to Improve HIV Testing Among Gay, Bisexual and Other Men Who Have Sex with Men: A Systematic Review

HIV testing is central to biomedical HIV prevention, but testing among men who have sex with men remains suboptimal. We evaluated effectiveness of mass media and communication interventions to increase HIV testing and explored patterns between study type, internal validity and intervention effectiveness for the first time. Five databases were searched for articles published between 2009 and 2016 using standard MeSH terms. Eligible studies were quality appraised using standard checklists for risk of bias. Data were extracted and synthesised narratively. Nineteen studies met inclusion criteria; 11 were cross-sectional/non-comparative studies, four were pre/post or interrupted time series, three were randomised controlled trials (RCTs) and one was a case study. Risk of bias was high. Five cross-sectional (two graded as high internal validity, one medium and two low) and one RCT (medium validity) reported increased HIV testing. Further work is required to develop and evaluate interventions to increase frequency and maintenance of HIV testing.

Comparative efficacy and safety and dolutegravir and lamivudine in treatment naive HIV patients

Objective:

Compare the efficacy and safety of the 2-drug antiretroviral therapy regimen dolutegravir + lamivudine (DTG + 3TC) with traditional 3-drug regimens in treatment-naive patients with HIV-1.

Design:

Data from double-blind, randomized controlled trials of at least 48 weeks’ duration in treatment-naive patients with HIV-1 identified by systematic review were evaluated using a Bayesian network meta-analysis methodology.

Methods:

The primary outcome was virologic suppression at Week 48 for 3-drug regimens versus DTG + 3TC (also analyzed in patient subgroup with baseline viral load >100 000 RNA copies/ml). Secondary outcomes included CD4⁺ cell count change from baseline and safety (adverse events, serious adverse events, and drug-related adverse events) at Week 48.

Results:

The network contains 14 unique regimens from 14 randomized controlled trials based on data from 10 043 patients. The proportional difference for viral suppression at 48 weeks for DTG + 3TC versus the other 13 regimens included in the network ranged from −2.7% (−11.0, 5.6%) versus DTG + tenofovir alafenamide/emtricitabine (FTC) to 7.3% (0.6, 13.8%) versus efavirenz + tenofovir disoproxil fumarate/FTC. DTG + 3TC was found to be significantly better than efavirenz + tenofovir disoproxil fumarate/FTC and similar to all other regimens analysed in terms of viral suppression at 48 weeks. With regard to other outcomes (CD4⁺, adverse event, serious adverse event, drug-related adverse events) at 48 weeks, DTG+3TC was broadly similar to all regimens analysed.

Conclusion:

This network meta-analysis demonstrates similar efficacy and safety outcomes over 48 weeks with DTG + 3TC compared with traditional 3-drug antiretroviral therapy regimens.

What are mass media interventions made of? Exploring the active content of interventions designed to increase HIV testing in gay men within a systematic review

PURPOSE

Mass media HIV testing interventions are effective in increasing testing, but there has been no examination of their theory or behaviour change technique (BCT) content. Within a heterogeneous body of studies with weak evaluative designs and differing outcomes, we attempted to gain useful knowledge to shape future interventions.

METHODS

Within a systematic review, following repeated requests to the authors of included studies for intervention materials, the Theory Coding Scheme, the Theoretical Domains Framework (TDF), and Behaviour Change Technique Taxonomy (BCTT) were used to extract data relating to active intervention content.

RESULTS

Of 19 studies, five reported an explicit theoretical basis to their intervention. TDF analysis highlighted the key domains employed within the majority of interventions: 'knowledge', 'social roles and identities', and 'beliefs about consequences'. BCT analysis showed three BCT groupings commonly reported within interventions: 'Comparison of outcomes', 'Natural consequences', and 'Shaping knowledge'. Three individual BCTs formed the backbone of most interventions and can be considered 'standard' content: 'Instructions on how to perform behaviour'; 'Credible source'; and 'Information about health consequences'.

CONCLUSIONS

This is the first study to examine and detail active intervention content in this field. It suggests future interventions should improve knowledge about testing, and use well-branded and trusted sources that endorse testing. Future interventions should also provide clear information about the health benefits of testing. Our analysis also suggests that to improve levels of effectiveness characterizing the current field, it may be useful to elicit commitment, and action plans, relating to how to implement testing intentions.

STATEMENT OF CONTRIBUTION

What is already known on this subject? Interventions are urgently needed to increase HIV testing among men who have sex with men (MSM) and enable increased access to effective treatment for HIV infection. There is some evidence of the effectiveness of mass media interventions in increasing HIV testing among MSM. Nothing is known about the active components of existing mass media interventions targeting HIV testing. What does this study add? It describes the available literature concerning evaluated mass media interventions to increase HIV testing. It shows few interventions report any explicit theoretical basis although many interventions share common components, including coherently connected causal mechanisms and behaviour change techniques to moderate them. As a minimum, future interventions should improve knowledge about testing; use well-branded and trusted sources that endorse testing; and provide clear information about the health benefits of testing. Our analysis also tentatively suggests it may be useful to elicit commitment and planning of how to implement testing intentions.

Efficacy and cost-effectiveness of early antiretroviral therapy and partners' pre-exposure prophylaxis among men who have sex with men in Shenyang, China: a prospective cohort and costing study

BACKGROUND

Biomedical interventions such as antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP) are highly effective for prevention of human immunodeficiency virus (HIV) infection. However, China has not released national PrEP guidelines, and HIV incidence among men who have sex with men (MSM) is unchanged despite substantial scale-up of ART. We evaluated reductions in HIV transmission that may be achieved through early initiation of ART plus partners' PrEP.

METHODS

Six intervention scenarios were evaluated in terms of their impact on HIV transmission and their cost-effectiveness for 36 months post-infection. Three scenarios were based on observed data: non-ART, standard-ART, and early-ART. Another three scenarios were based on observed and hypothetical data: non-ART plus partners' PrEP, standard-ART plus partners' PrEP, and early-ART plus partners' PrEP. The number of onward transmissions was calculated according to viral load and self-reported sexual behaviors, and calibrated by the prevalence and incidence of HIV among Chinese MSM. Cost-effectiveness outcomes were quality-adjusted life-years (QALYs) and cost-utility ratio (CUR).

RESULTS

The estimated number of onward transmissions by every 100 HIV-positive cases 36 months post-infection was 41.83 (95% credible interval: 30.75-57.69) in the non-ART scenario, 7.95 (5.85-10.95) in the early-ART scenario, and 0.79 (0.58-1.09) in the early-ART plus partners' PrEP scenario. Compared with non-ART, the early-ART and early-ART plus partners' PrEP scenarios were associated with an 81.0 and 98.1% reduction in HIV transmission, and had a CUR of $12,864/QALY and $16,817/QALY, respectively.

CONCLUSIONS

Integrated delivery of early ART and sexual partners' PrEP could nearly eliminate HIV transmission and reduce costs during the first 36 months of HIV infection. Our results suggest a feasible and cost-effective strategy for reversing the HIV epidemic among MSM in China.

Changes health-related quality of life in HIV-infected patients following initiation of antiretroviral therapy: a longitudinal study

BACKGROUND

Several tools have been developed to evaluate HIV health-related quality of life (HRQoL) during and after antiretroviral therapy (ART). Few longitudinal studies evaluated the effect of ART on the quality of life of HIV patients.

OBJECTIVE

To evaluate changes in HRQoL in HIV-infected individuals one year after initiating ART.

METHODS

A prospective study was conducted from May 2016 to July 2018. Data on clinical and sociodemographic characteristics of 91 HIV-infected patients were collected prior to initiation of ART and one year thereafter. Demographic and clinical data were collected and the questionnaires 36-item Short Form Health Survey (SF-36) and HIV/AIDS-targeted quality of life (HAT-QoL) were administered in both periods. Asymptomatic individuals, aged ≥18 years, were included in the study. Patients who discontinued treatment were excluded. The association between predictors of physical and mental HRQoL was analyzed by multiple linear regression analysis.

RESULTS

Patients were predominantly male (78.0%), mean age 35.3 ± 10.7 years, with no stable relationship (80.2%), and no comorbidities (73.6%). Most of the SF-36 domains improved after one year, particularly Physical Function (p = 0.0001), General Health (p = 0.0001), Social Functioning (p = 0.0001), Mental Health (p = 0.001), and Mental Component Summary (p = 0.004). HAT-QoL domains improved in the Overall Function (p = 0.0001), Life Satisfaction (p = 0.0001), Provider Trust (p = 0.001), and Sexual Function (p = 0.0001) domains. Sex (p = 0.032), age (p = 0.001), income (p = 0.007), and stable relationship (p = 0.004) were good predictors of the Physical Component Summary. Sex (p = 0.002) and stable relationship (p = 0.038) were good predictors of the Mental Component Summary. SF-36 and HAT-QoL scales presented strong correlations, except for Medication Concerns (0.15-0.37), HIV Mastery (0.18-0.38), Disclosure Worries (-0.15 to 0.07), and Provider Trust (-0.07 to 0.15).

CONCLUSIONS

ART improved HRQoL after one year of use. The HAT-QoL and SF-36 correlated well and are good tools to evaluate HRQoL in HIV-infected patients on ART.

Cascade of care for HIV-seroconverters in rural Tanzania: a longitudinal study

We examined the HIV care cascade in a community-based cohort study in Kisesa, Magu, Tanzania. We analyzed the proportion achieving each stage of the cascade - Seroconversion, Awareness of HIV status, Enrollment in Care and Antiretroviral therapy (ART) initiation - and estimated the median and interquartile range for the time for progression to the next stage. Modified Poisson regression was used to estimate prevalence risk ratios for enrollment in care and initiation of ART. From 2006 to 2017, 175 HIV-seroconverters were identified. 140 (80%) knew their HIV status, of whom 97 (69.3%) were enrolled in HIV care, and 87 (49.7%) had initiated ART. Time from seroconversion to awareness of HIV status was 731.3 [475.5-1345.8] days. Time from awareness to enrollment was 7 [0-64] days, and from enrollment to ART initiation was 19 [3-248] days. There were no demographic differences in enrollment in care or ART initiation. Efforts have been focusing on shortening time from seroconversion to diagnosis, mostly by increasing the number of testing clinics available. We recommend increased systematic testing to reduce time from seroconversion to awareness of status, and by doing so speed up enrollment into care. Interventions that increase enrollment are likely to have the most impact in achieving UNAIDS targets.

Outcome of an HIV education program for primary care providers: Screening and late diagnosis rates

Background

Late HIV diagnosis remains one of the challenges in combating the epidemic. Primary care providers play an important role in screening for HIV infection. Our study aims to evaluate the relationship between knowledge and barriers to HIV testing and screening outcomes. The impact of an education program for primary care providers, towards improving HIV testing and late diagnosis rates, is also assessed.

Methods

A self-administered questionnaire that was developed within the framework of the European project OptTEST was used to examine HIV knowledge and barriers to HIV testing scores before and after being involved in an HIV education program. A quasi-experimental design with pre- and post-intervention measures was performed to investigate its impact. We performed multivariable logistic regression analysis to assess the relationship between variables for the HIV testing offer.

Results

A total of 20 primary care centers and 454 primary care staff were included. Baseline OptTEST results showed that more knowledgeable staff offered an HIV test more frequently (OR 1.07; CI 95% 1.01–1.13; p = 0.027) and had lower barrier scores (OR 0.89; CI 95% 0.77–0.95; p = 0.005). Nurses had lower scores in knowledge-related items (OR 0.28; CI 95% 0.17–0.46; p<0.001), but higher scores in barrier-related items than physicians (OR 3.28; CI 95% 2.01–5.46; p<0.001). Specific centers with more knowledgeable staff members had a significant association with a greater level of new HIV diagnosis rates (OR 1.61; CI 95% 1.04–2.49; p = 0.032). After the intervention, we found that 12 out of 14 individual questions showed improved scores. In the 6 months after the training program, we similarly found a higher HIV testing rate (OR 1.19; CI 1.02–1.42; p = 0.036).

Conclusions

This study highlights the association between knowledge and barriers to HIV testing, including HIV testing rates. It shows that it is possible to modify knowledge and reduce perceived barriers through educational programs, subsequently improving HIV screening outcomes.

Trajectory of change in anxiety sensitivity in relation to anxiety, depression, and quality of life among persons living with HIV/AIDS following transdiagnostic cognitive-behavioral therapy

Persons living with HIV/AIDS (PLHIV) disproportionately suffer from anxiety and depressive symptoms and disorders. Although past work has examined the efficacy of cognitive-behavioral therapy (CBT) for depression, and to a lesser extent anxiety, among PLHIV, little is known regarding potential mechanisms underlying improvement in anxiety/depression among this group. Anxiety sensitivity is a well-established risk/maintenance factor for anxiety and depressive disorders and is hypothesized to play an important role in maintaining anxiety among PLHIV. Past work has identified anxiety sensitivity as a mechanism of action underlying changes in various anxiety domains yet it is unknown whether changes in anxiety sensitivity relate to changes in anxiety symptoms among PLHIV undergoing transdiagnostic CBT for anxiety. The current study sought to examine treatment-related changes in anxiety sensitivity and how the trajectory of change relates to anxiety and depressive symptoms as well as overall quality of life. Individuals (n = 35) with HIV/AIDS and elevated anxiety symptoms received CBT for anxiety. Results indicated that reductions in anxiety sensitivity were significantly related to changes in anxiety, depression, and quality of life. Together, these data suggest that changes in anxiety sensitivity are significantly related to changes in anxiety/depression and quality of life among PLHIV seeking treatment.

The influence of constraints on the efficient allocation of resources for HIV prevention

OBJECTIVE

To investigate how 'real-world' constraints on the allocative and technical efficiency of HIV prevention programmes affect resource allocation and the number of infections averted.

DESIGN

Epidemiological modelling and economic analyses in Benin, South Africa and Tanzania.

METHODS

We simulated different HIV prevention programmes, and first determined the most efficient allocation of resources, in which the HIV prevention budget is shared among specific interventions, risk-groups and provinces to maximize the number of infections averted. We then identified the efficient allocation of resources and achievable impact given the following constraints to allocative efficiency: earmarking [provinces with budgets fund pre-exposure prophylaxis (PrEP) for low-risk women first], meeting targets [provinces with budgets fund universal test-and-treat (UTT) first] and minimizing changes in the geographical distribution of funds. We modelled technical inefficiencies as a reduction in the coverage of PrEP or UTT, which were factored into the resource allocation process or took effect following the allocation. Each scenario was investigated over a range of budgets, such that the impact reaches its maximum.

RESULTS

The 'earmarking', 'meeting targets' and 'minimizing change' constraints reduce the potential impact of HIV prevention programmes, but at the higher budgets these constraints have little to no effect (approximately 35 billion US$ in Tanzania). Over-estimating technical efficiency can result in a loss of impact compared to what would be possible if technical efficiencies were known accurately.

CONCLUSION

Failing to account for constraints on allocative and technical efficiency can result in the overestimation of the health gains possible, and for technical inefficiencies the allocation of an inefficient strategy.

Life expectancy and disparities in survival among HIV-infected people receiving antiretroviral therapy: an observational cohort study in Kathmandu, Nepal

Introduction

The advent of antiretroviral therapy (ART) has dramatically slowed down the progression of HIV. This study assesses the disparities in survival, life expectancy and determinants of survival among HIV-infected people receiving ART.

Methods

Using data from one of Nepal’s largest population-based retrospective cohort studies (in Kathmandu, Nepal), we followed a total of 3191 HIV-infected people aged 15 years and older who received ART over the period of 2004–2015. We created abridged life tables with age-specific survival rates and life expectancy, stratified by sex, ethnicity, CD4 cell counts and the WHO-classified clinical stage at initiation of ART.

Results

HIV-infected people who initiated ART with a CD4 cell count of >200 cells/cm³ at 15 years had 27.4 (22.3 to 32.6) years of additional life. People at WHO-classified clinical stage I and 15 years of age who initiated ART had 23.1 (16.6 to 29.7) years of additional life. Life expectancy increased alongside the CD4 cell count and decreased as clinical stages progressed upward. The study cohort contributed 8484.8 person years, with an overall survival rate of 3.3 per 100 person years (95% CI 3.0 to 3.7).

Conclusions

There are disparities in survival among HIV-infected people in Nepal. The survival payback of ART is proven; however, late diagnosis or the health system as a whole will affect the control and treatment of the illness. This study offers evidence of the benefits of enrolling early in care in general and ART in particular.

HIV infection epidemiology: a change of scenery

Combination antiretroviral therapy has completely changed the landscape of HIV infection through the control of viral replication of the virus, the restoration of the immune system damage, and the reduction of the complications associated with immunodeficiency. As a consequence, the average age of people living with HIV has been increasing progressively, with a high proportion of diagnosed, as well as newly diagnosed, HIV-infected patients being older than 50 years throughout the world. With the longer life expectancy, characteristics commonly observed in aging are occurring in people with long-term HIV infection, including multiple chronic diseases, changes in cognitive and physical abilities, and the use of multiple medications. HIV-related specific factors, as well as a higher prevalence of environmental, classical factors, increase the risk of comorbidities in the aging HIV-infected population. A close collaboration between different specialists (HIV specialists, geriatricians, primary care physicians, and other specialists) is required to manage the clinical problems that older HIV-infected patients may present.

The influence of the 'good' patient ideal on engagement in HIV care

Research on patient engagement in health care shows that better health outcomes and lower healthcare costs are observed among highly engaged patients. Similar to other illnesses, high levels of patient engagement in HIV care are considered essential to maintaining optimal health, and patients who are on treatment and retained in HIV care are known to have better health outcomes. In this article, we draw on focus group discussion data with patients living with HIV in order to explain tacit expectations associated with engagement in care. The main objective of our research was to elicit an explanatory model of engagement in HIV care from the patients’ perspective. We conducted focus group discussions with a sample of two distinct types of patients: those who regularly attended medical appointments and those who did not. In total, we conducted six focus group discussions (n = 43) across in three cities in the US; these included two focus group discussions with a well-engaged and less-well-engaged group in each location. Both types of patients assigned a moral dimension to engagement in care, in that well-engaged patients were considered to be ‘good’ patients. Aspiring to become a ‘good’ patient provided a meaningful goal for some and deepened vulnerabilities among patients that struggled to achieve this status. More vulnerable patients may feel less secure in health care interactions and these feelings may be amplified if patients have an unreasonable impression of what constitutes a ‘good’ patient; thereby leading to disengagement in care. Our findings can inform the development of patient-centered, tailored messages to better serve patients struggling to stay engaged in HIV care.

'We are the change' - An innovative community-based response to address self-stigma: A pilot study focusing on people living with HIV in Zimbabwe

Introduction

Self-stigma–negative self-judgements resulting in shame, worthlessness and self-blame–may play a crucial role in emotional reactions and cause emotional distress among many people living with HIV and other chronic illnesses. Furthermore, self-stigma negatively impacts on self-agency, quality of life, adherence to treatment, and access to services. High levels of self-stigma have been reported across many countries, however few programmes or interventions exist to specifically tackle this phenomenon. This paper reports the findings of a pilot study carried out in Zimbabwe using a programme incorporating “Inquiry-Based Stress Reduction (IBSR): The Work of Byron Katie”–a guided form of self-inquiry which helps users to overcome negative thoughts and beliefs.

Objectives

The primary objective of this uncontrolled pilot study was to examine the potential role of the IBSR intervention in helping people living with HIV to overcome self-stigma and associated states.

Methods

23 people living with HIV (17 Female, 6 male, average age 41 years) were recruited from a local HIV support network, via open call for volunteers. All participants received the intervention, consisting of a 12-week facilitated programme using techniques derived from IBSR: The Work of Byron Katie. Qualitative and quantitative data were collected and analysed pre- and post-programme.

Results

After taking part in the intervention, participants reported significant improvements in factors including self-stigma (1-month follow-up vs baseline Z = 2.1, p = 0.039; 3-month follow-up vs baseline Z = 3.0, p = 0.003, n = 23, Wilcoxon Matched Pairs Signed Rank Test) and depression (1mo vs baseline Z = 3.7, p = <0.001; 3mo vs baseline Z = 3.3, p = 0.001). Qualitatively, participants reported improvements including lessened fears around disclosure of their HIV status, reduced feelings of life limitations due to HIV, and greater positive mentality. Improvements persisted at three-month follow-up.

Conclusion

With further development and larger comparative studies to confirm effects, the IBSR programme could become a novel tool to enable people living with HIV to support themselves in overcoming self-stigma.

Chronic kidney disease, cardiovascular disease, and osteoporotic fractures in patients with and without HIV in the US Veteran's Affairs Administration System

Objective: To evaluate the risk of chronic kidney disease (CKD), cardiovascular disease (CVD), and osteoporotic fractures in human immunodeficiency virus (HIV) patients utilizing data within the Veteran's Affairs (VA) Administration system.Methods: A retrospective cohort study utilizing VA system claims (January 2000-December 2016) were extracted from the VA Informatics and Computing Infrastructure (VINCI). Cases included Veterans with an ICD-9/10 for HIV who had at least one prescription for a complete antiretroviral therapy (ART) regimen. Two non-HIV controls were exactly matched on race, sex, month, and year of birth. All patients were followed until the earliest of the following: first incidence of the outcome (identified based on diagnosis codes or laboratory data), last date of VA activity, death, or December 31, 2016. Relative risks (RR) and odds ratios (ORs) were estimated from multivariable Poisson regression models (CVD and osteoporotic fractures) and multivariable logistic regression models (CKD), respectively. Models were adjusted for demographic factors/comorbidities.Results: A total of 79,578 patients (26,526 HIV and 53,052 non-HIV) met all study criteria. The average age was 49.3 years, 38% were black, 32% were white, and 97% were male for both the HIV and control cohorts. The adjusted models demonstrated that HIV was associated with a 78% increased rate of CKD (OR = 1.78, 95% CI = 1.68-1.89), a 32% increased risk of CVD (RR = 1.32, 95% CI = 1.28-1.37), and a 38% increased risk of fractures (RR = 1.38, 95% CI = 1.23-1.56) compared to non-HIV controls.Conclusions: The risk/rate of the three outcomes were significantly higher in HIV patients compared to controls.

Changes and determinants of health-related quality of life among people newly diagnosed with HIV in China: a 1-year follow-up study

PURPOSE

This study aimed to investigate changes in health-related quality of life (HRQoL) among people newly diagnosed with HIV and to identify factors associated with HRQoL.

METHODS

Newly diagnosed HIV-positive individuals were consecutively recruited and assessed at baseline and 1-year follow-up after diagnosis. HRQoL was measured through the physical health summary score (PHS) and mental health summary score (MHS) derived from the Medical Outcomes Study HIV Health Survey. Socio-demographic, clinical, and psychological information was also collected at both times. Generalized estimating equations were applied to explore factors associated with HRQoL in 1 year.

RESULTS

A total of 410 participants were included. After 1 year, significant increases were observed for both the mean PHS score (53.5-55.0; p = 0.009) and the mean MHS score (44.2-49.0; p < 0.001). Older age (p = 0.024), rural household registration (p = 0.031), HIV-related symptoms (p < 0.001), and depression (p = 0.014) were negatively associated with PHS. Additionally, the negative association between stress and PHS increased over time (β = - 0.07 for the baseline; β = - 0.18 for the 12-month follow-up; p < 0.001). HIV-related symptoms, depression, lower social support, and higher levels of stress (all p < 0.001) were negatively associated with MHS. Additionally, the negative relationship between stress and MHS was stronger among participants who were asymptomatic (p = 0.015).

CONCLUSION

A relatively lower HRQoL among HIV-infected people shortly after HIV diagnosis and an increase in HRQoL among people 1 year after HIV diagnosis were observed. Additional attention should be paid to individuals of older age, from rural areas, with HIV-related symptoms, with depression, with high levels of stress, and with a lack of social support.

Trends in mortality among ART-treated HIV-infected adults in the Asia-Pacific region between 1999 and 2017: results from the TREAT Asia HIV Observational Database (TAHOD) and Australian HIV Observational Database (AHOD) of IeDEA Asia-Pacific

INTRODUCTION

AIDS-related deaths in people living with HIV/AIDS have been decreasing in number since the introduction of combination antiretroviral treatment (cART). However, data on recent causes of death in the Asia-Pacific region are limited. Hence, we analysed and compared AIDS-related and non-AIDS-related mortality in high- and low-income settings in the region.

METHODS

Patients from the TREAT Asia HIV Observational Database (TAHOD) and Australian HIV Observational Database (AHOD) receiving cART between 1999 and 2017 were included. Causes of death verification were based on review of the standardized Cause of Death (CoDe) form designed by the D:A:D group. Cohorts were grouped as AHOD (all high-income sites), TAHOD-high (high/upper-middle income countries) and TAHOD-low (lower-middle income countries). TAHOD sites were split into high/upper-middle income and lower-middle income country settings based on World Bank classifications. Competing risk regression was used to analyse factors associated with AIDS and non-AIDS-related mortality.

RESULTS

Of 10,386 patients, 522 died; 187 from AIDS-related and 335 from non-AIDS-related causes. The overall incidence rate of deaths during follow-up was 0.28 per 100 person-years (/100 PYS) for AIDS and 0.51/100 PYS for non-AIDS. Analysis indicated that the incidence rate of non-AIDS mortality decreased from 0.78/100 PYS to 0.37/100 PYS from year groups 2003 to 2007 to 2013 to 2017 (p < 0.001). Similarly, incidence rates of AIDS-related deaths decreased from 0.51/100 PYS to 0.09/100 PYS from year groups 2003 to 2007 to 2013 to 2017 (p < 0.001). More recent years of follow-up were associated with reduced hazard for non-AIDS mortality (2008 to 2012: aSHR (adjusted sub-hazard ratio) 0.72, 95% confidence interval (CI) 0.54 to 0.96, p = 0.027; 2013 to 2017: aSHR 0.64, 95% CI 0.47 to 0.87, p = 0.004) compared to years 2003 to 2007. The AHOD cohort had almost twice the hazard of non-AIDS mortality compared to TAHOD-low (lower-middle income sites) (aSHR 1.72, 95% CI, 1.20 to 2.46, p = 0.003); there were no differences between cohorts for AIDS-related mortality (p = 0.834).

CONCLUSION

AIDS and non-AIDS-related mortality rates have decreased over the past years in the Asia-Pacific region. There is a greater risk for non-AIDS-associated deaths in the AHOD cohort compared to lower-middle income settings in TAHOD.

Frailty among HIV-1 Infected Adults under Antiretroviral Therapy in Indonesia

BACKGROUND

Increasing age of HIV-1 infected population brought about the risk of frailty as comorbidity, whose prevalence is higher in low and middle-income countries (LMICs). Indonesia as an LMIC also bears a major burden of HIV-1 epidemic with a similarly aging population, but the prevalence of frailty and its predictors are unknown.

OBJECTIVES

To identify the prevalence of frailty and analyze its associated factors, among HIV-1 infected adults under antiretroviral therapy in Indonesia.

METHODS

A cross-sectional study was conducted among HIV-infected individuals with inclusion criteria of age ≥30 years old and underwent ART for at least 6 months. The main assessment was done using Fried's frailty phenotype score, which categorizes subjects into non-frail, pre-frail, or frail. Factors associated with frailty were characterized and multiple logistic regression analysis was performed.

RESULTS

A total of 164 subjects were recruited; male subjects were 118 (72%), the median age was 40.5 years old, and the median CD4 nadir was 53 cells/μl. Frailty was identified among 90 (54.9%) subjects with 84 (51.2%) identified as pre-frail and 6 (3.7%) as frail, with dominant frailty phenotype was weakness in grip strength. The multivariate model showed that depression was the only factor significantly correlated with pre-frailty and frailty (OR 2.14; 95% CI 1.04-4.43, p=0.036).

CONCLUSION

Frailty is a common occurrence among HIV-infected patients under ART, with depression as an independent predictive factor.

Response to anti-tuberculosis treatment by people over age 60 in Kampala, Uganda

While old age is a known risk factor for developing active tuberculosis (TB), studies on TB in the population aged 60 years and older (considered elderly in this study) are few, especially in the developing world. Results of the TB prevalence survey in Uganda found high TB prevalence (570/100,000) in people over 65. We focused on treatment outcomes in the elderly to understand this epidemic better. We conducted a retrospective analysis of data from TB facility registers in Kampala City for the period 2014-2015. We analyzed the 2014-15 cohort with respect to age, sex, disease class, patients' human immunodeficiency virus (HIV) and directly observed therapy (DOT) status, type of facility, and treatment outcomes and compared findings in the elderly (≥60) and younger (<60) age groups. Of 15,429 records, 3.3% (514/15,429) were for elderly patients. The treatment success rate (TSR) among elderly TB patients (68.3%) was lower than that of the non-elderly (80.9%) and the overall TSR 80.5%, (12,417/15,429) in Kampala. Although the elderly were less likely to test positive for HIV than the young (AOR 0.39; 95% CI 0.33-0.48, p<0.001), they had a two-fold higher risk of unfavorable treatment outcomes (AOR 2.14; CI 1.84-2.72, p<0.001) and were more likely to die while on treatment (AOR 1.86; CI 1.27-2.73; p = 0.001). However, there was no statistically significantly difference between treatment outcomes among HIV-positive and HIV-negative elderly TB patients. Compared to the younger TB patients, elderly TB patients have markedly poorer treatment outcomes, although TB/HIV co-infection rates in this age group are lower.

The systematic development of a complex intervention: HealthMap, an online self-management support program for people with HIV

Background

Despite persistent calls for HIV care to adopt a chronic care approach, few HIV treatment services have been able to establish service arrangements that prioritise self-management. To prevent cardiovascular and other chronic disease outcomes, the HealthMap program aims to enhance routine HIV care with opportunities for self-management support. This paper outlines the systematic process that was used to design and develop the HealthMap program, prior to its evaluation in a cluster-randomised trial.

Methods

Program development, planning and evaluation was informed by the PRECEDE-PROCOEDE Model and an Intervention Mapping approach and involved four steps: (1) a multifaceted needs assessment; (2) the identification of intervention priorities; (3) exploration and identification of the antecedents and reinforcing factors required to initiate and sustain desired change of risk behaviours; and finally (4) the development of intervention goals, strategies and methods and integrating them into a comprehensive description of the intervention components.

Results

The logic model incorporated the program’s guiding principles, program elements, hypothesised causal processes, and intended program outcomes. Grounding the development of HealthMap on a clear conceptual base, informed by the research literature and stakeholder’s perspectives, has ensured that the HealthMap program is targeted, relevant, provides transparency, and enables effective program evaluation.

Conclusions

The use of a systematic process for intervention development facilitated the development of an intervention that is patient centred, accessible, and focuses on the key determinants of health-related outcomes for people with HIV in Australia. The techniques used here may offer a useful methodology for those involved in the development and implementation of complex interventions.

Sexuality and childbearing as it is experienced by women living with HIV in Sweden: a lifeworld phenomenological study

The effectiveness of antiretroviral treatment has reduced sexual HIV transmission and mother-to-child-transmission. To optimally support women living with HIV, health care providers need deepened knowledge about HIV, sexuality and childbearing. The aim of this study was to describe the phenomenon sexuality and childbearing as experienced by women living with HIV in Sweden. Data were collected by phenomenon-oriented interviews with 18 HIV-positive women. A reflective lifeworld analysis based on phenomenological philosophy was conducted, describing the meaning structure of the phenomenon. The essence of the phenomenon is that perceptions about HIV and its contagiousness profoundly influence sexual habits and considerations in relation to pregnancy and childbearing. These perceptions are formed in combination with knowledge and interpretations about HIV by the women themselves and by their environments. The essence is further described by its constituents: Risk of transmission imposes demands on responsibility; The contagiousness of HIV limits sexuality and childbearing; Knowledge about HIV transmission provides confident choices and decisions; and To re-create sexuality and childbearing. Although HIV has a low risk of transmission if being well treated, our study shows that HIV-positive women feel more or less contagious, which influences sexuality and decision-making in relation to become pregnant and give birth.

Late diagnosis, delayed presentation and late presentation among persons enrolled in a clinical HIV cohort in Ontario, Canada (1999-2013)

OBJECTIVES

Timely HIV diagnosis and presentation to medical care are important for treatment and prevention. Our objective was to measure late diagnosis, delayed presentation and late presentation among individuals in the Ontario HIV Treatment Network Cohort Study (OCS) who were newly diagnosed in Ontario.

METHODS

The OCS is a multi-site clinical cohort study of people living with HIV in Ontario, Canada. We measured prevalence of late diagnosis [CD4 count < 350 cells/μL or an AIDS-defining condition (ADC) within 3 months of HIV diagnosis], delayed presentation (≥ 3 months from HIV diagnosis to presentation to care), and late presentation (CD4 count < 350 cells/μL or ADC within 3 months of presentation). We identified characteristics associated with these outcomes and explored their overlap.

RESULTS

A total of 1819 OCS participants were newly diagnosed in Ontario from 1999 to 2013. Late diagnosis (53.0%) and presentation (54.0%) were common, and a quarter (23.1%) of participants were delayed presenters. In multivariable models, the participants of delayed presentation decreased over calendar time, but that of late diagnosis/presentation did not. Late diagnosis contributed to the majority (> 87%) of late presentation, and the prevalence of delayed presentation was similar among those diagnosed late versus early (13.4 versus 13.4%, respectively; P = 0.99). Characteristics associated with higher odds of late diagnosis/presentation in multivariable analyses included older age at diagnosis/presentation; African, Caribbean and Black race/ethnicity; Indigenous race/ethnicity; female sex; and being a male who did not report sex with men. There were lower odds of late diagnosis/presentation among participants who had ever injected drugs. In contrast, delayed presentation risk factors included younger age at diagnosis and having ever injected drugs.

CONCLUSIONS

Late presentation is common in Ontario, as it is in other high-income countries. Our findings suggest that efforts to reduce late presentation should focus on facilitating earlier diagnosis for the populations identified in this analysis.

Does Economic Strengthening Improve Viral Suppression Among Adolescents Living with HIV? Results From a Cluster Randomized Trial in Uganda

To assess the effect of a savings-led economic empowerment intervention on viral suppression among adolescents living with HIV. Using data from Suubi + Adherence, a longitudinal, cluster randomized trial in southern Uganda (2012-2017), we examine the effect of the intervention on HIV RNA viral load, dichotomized between undetectable (< 40 copies/ml) and detectable (≥ 40 copies/ml). Cluster-adjusted comparisons of means and proportions were used to descriptively analyze changes in viral load between study arms while multi-level modelling was used to estimate treatment efficacy after adjusting for fixed and random effects. At 24-months post intervention initiation, the proportion of virally suppressed participants in the intervention cohort increased tenfold (Δ_T2-T0 = + 10.0, p = 0.001) relative to the control group (Δ_T2-T0 = + 1.1, p = 0.733). In adjusted mixed models, simple main effects tests identified significantly lower odds of intervention adolescents having a detectable viral load at both 12- and 24-months. Interventions addressing economic insecurity have the potential to bolster health outcomes, such as HIV viral suppression, by improving ART adherence among vulnerable adolescents living in low-resource environments. Further research and policy dialogue on the intersections of financial security and HIV treatment are warranted.

HIV testing amongst older sexual health clinic attendees in England: an epidemiological study

Older adults with HIV are at increased risk of late diagnosis. We aimed to explore the association between age and HIV testing rates in sexual health clinics in England using Public Health England data for 2009-2014. We investigated associations between attendee age and likelihood of HIV test offer, acceptance, and coverage. For each year, increasing age was associated with reduced likelihood of test offer (R_s -0.797 to -0.958, p < 0·01). Offer rates were highest for men who have sex with men (MSM), and lowest for heterosexual females (HSFs). HSFs had the greatest decline in offer rates with age (from 86.2% for age 25-29 to 52.1% for age 70+ in 2014). Odds ratios for test offer in 2014 for attendees aged 15-49 compared with attendees aged 50+ were 1.94 (95%CI: 1.88, 2.00) for heterosexual males (HSMs), 1.86 (95%CI: 1.81, 1.91) for HSFs, and 1.54 (95%CI: 1.45, 1.64) for MSM. Overall, there was no significant association between age and test acceptance in any year (R_s -0.070 to -0.547; p > 0·05). The strongest determinant of acceptance was sexual orientation; for attendees aged 50+, compared with HSMs, acceptance was higher for MSM (OR: 1.10; 95%CI: 1.06, 1.13) and lower for HSFs (OR: 0.30; 95%CI: 0.30, 0.31).

Chronic Binge Alcohol-Induced Dysregulation of Mitochondrial-Related Genes in Skeletal Muscle of Simian Immunodeficiency Virus-Infected Rhesus Macaques at End-Stage Disease

Aims

Alcohol use disorders are more prevalent in HIV patients than the general population. Both chronic alcohol consumption and HIV infection have been linked to mitochondrial dysregulation; and this is considered an important mechanism in the pathogenesis of muscle myopathy. This study investigated if chronic binge alcohol (CBA) administration impairs the expression of genes involved in mitochondrial homeostasis in SIV-infected macaques.

Methods

Male rhesus macaques were administered daily CBA (to achieve peak blood alcohol concentrations of 50-60 mM within 2 h after start of infusion) or sucrose (SUC) intragastrically 3 months prior to intravenous SIVmac251 inoculation and continued until macaques met criteria for end-stage disease. Skeletal muscle (SKM) samples were obtained at necropsy. Muscle samples were obtained from a cohort of healthy uninfected macaque controls and used for comparison of analyzed variables. Total RNA was extracted and gene expression was analyzed by quantitative polymerase chain reaction.

Results

The relative expression of peroxisome proliferator-activated receptor gamma coactivator-1 beta (PGC-1β) was significantly decreased in the SKM of CBA/simian immunodeficiency virus (SIV) macaques compared to uninfected controls (P < 0.05). SIV infection resulted in a significant upregulation (P < 0.05) of mitophagy-related gene expression, which was prevented by CBA. CBA suppressed expression of anti-apoptotic genes and increased expression of pro-apoptotic genes (P < 0.05).

Conclusions

These findings suggest that SIV infection disrupts mitochondrial homeostasis and when combined with CBA, results in differential expression of genes involved in apoptotic signaling. We speculate that impaired mitochondrial homeostasis may contribute to the underlying pathophysiology of alcoholic and HIV/AIDS associated myopathy.

Short summary

This study investigated if CBA administration dysregulates gene expression associated with mitochondrial homeostasis in the SKM of SIV-infected macaques. The results suggest that SIV infection disrupts mitochondrial homeostasis and when combined with CBA, results in differential expression of genes involved in apoptotic signaling.

Estimating epidemiological parameters of a stochastic differential model of HIV dynamics using hierarchical Bayesian statistics

Current estimates of the HIV epidemic indicate a decrease in the incidence of the disease in the undiagnosed subpopulation over the past 10 years. However, a lack of access to care has not been considered when modeling the population. Populations at high risk for contracting HIV are twice as likely to lack access to reliable medical care. In this paper, we consider three contributors to the HIV population dynamics: at-risk population exhaustion, lack of access to care, and usage of anti-retroviral therapy (ART) by diagnosed individuals. An extant problem in the mathematical study of this system is deriving parameter estimates due to a portion of the population being unobserved. We approach this problem by looking at the proportional change in the infected subpopulations. We obtain conservative estimates for the proportional change of the infected subpopulations using hierarchical Bayesian statistics. The estimated proportional change is used to derive epidemic parameter estimates for a system of stochastic differential equations (SDEs). Model fit is quantified to determine the best parametric explanation for the observed dynamics in the infected subpopulations. Parameter estimates derived using these methods produce simulations that closely follow the dynamics observed in the data, as well as values that are generally in agreement with prior understanding of transmission and diagnosis rates. Simulations suggest that the undiagnosed population may be larger than currently estimated without significantly affecting the population dynamics.

Behavioural, not biological, factors drive the HCV epidemic among HIV-positive MSM: HCV and HIV modelling analysis including HCV treatment-as-prevention impact

Background

Uncertainty surrounds why hepatitis C virus (HCV) is concentrated among HIV-positive men who have sex with men (MSM). We used mathematical modelling to explore reasons for these infection patterns, and implications for HCV treatment-as-prevention.

Methods

Using a joint MSM HIV/HCV transmission model parameterized with UK behavioural data, we considered how biological (heightened HCV infectivity and reduced spontaneous clearance among HIV-positive MSM) and/or behavioural factors (preferential sexual mixing by HIV status and risk heterogeneity) could concentrate HCV infection in HIV-positive MSM as commonly observed (5-20 times the HCV prevalence in HIV-negative MSM; defined as the HCV ratio). We explored how HCV treatment-as-prevention impact varies under differing HCV ratios.

Results

Biological factors produced low HCV ratios (< 3), not explaining the skewed epidemic. However, combining preferential mixing by HIV status with sexual risk behaviour heterogeneity produced high HCV ratios (> 10) that were highly sensitive to both factors. Irrespective of the HCV ratio or behavioural/biological factors, HCV treatment of HIV-diagnosed MSM markedly reduced the HCV prevalence among HIV-positive MSM, but less impact was achieved among all MSM for lower HCV ratios.

Conclusions

Sexual behaviour patterns likely drive observed HCV infection patterns among HIV-positive MSM. Changes in these patterns could disseminate HCV amongst HIV-negative MSM, limiting the impact of targeting HCV treatment to HIV-diagnosed MSM.

Validation of Retention in HIV Care Status Using the New York City HIV Surveillance Registry and Clinical Care Data From a Large HIV Care Center

Supplemental Digital Content is Available in the Text.

Context:

Improving retention in care is a key element of the National HIV/AIDS Strategy (NHAS). However, definitions for measuring retention in care are not standardized.

Objective:

To compare measures of retention based on both clinic visit data and HIV laboratory surveillance data.

Design:

Retrospective cohort study.

Setting:

New York City (NYC), New York.

Participants:

We matched adult patients with HIV infection seen at the Spencer Cox Center for Health (SCC) in 2010 or 2011 with the NYC HIV Surveillance Registry.

Main Outcome Measures:

Retention in care was measured on the basis of SCC electronic medical record (EMR) data (≥1 medical visits in 2012) and Surveillance Registry data (≥2 CD4/viral load [VL] tests ≥90 days apart in 2012).

Results:

There were 5746 adult HIV-infected patients seen at SCC between 2010 and 2011 who matched with the Surveillance Registry. Seventy-eight percent (n = 4469) had 1 or more medical visits at SCC in 2012 and were considered retained on the basis of the EMR definition, among which 3831 (86%) met the surveillance definition for retention in care. Patients who did not have a medical visit at SCC in 2012 (n = 1277) were lost to care in NYC (n = 485; 36%), engaged in care at an alternate provider (n = 622; 49%), or died after their last SCC visit (n = 197; 15%).

Implications:

This study is an important comparison of laboratory surveillance versus clinic visit-based measures of retention in care in an urban setting with the largest HIV epidemic in the country. Collaborative projects between local health departments and clinical care providers can help validate the care status of patients and inform the allocation of resources to reengage patients who are lost to care.

Conclusion:

The combined use of laboratory and clinic visit–based data to measure retention in care provides a more accurate representation of the care status of HIV-infected patients than use of a single data source alone. Routine sharing of data by public health institutions and clinical care providers would help target resources toward reengaging patients who are lost to care in jurisdictions with universal HIV-related laboratory reporting.

Immune reconstitution in ART treated, but not untreated HIV infection, is associated with abnormal beta cell function

HIV infection has been associated with increased diabetes risk, but prior work has mostly focused on insulin resistance, as opposed to beta cell effects, or included patients on antiretroviral therapies (ART) directly linked to metabolic toxicity. In this analysis, we measured markers of glucose homeostasis and beta cell function, stress, and death in fasting sera from a cross section of HIV+ individuals off ART (n = 43), HIV+ individuals on ART (n = 23), and HIV- controls (n = 39). Markers included glucose, HOMA%S, HOMA%B, proinsulin:C-peptide ratio (PI:C ratio), and circulating preproinsulin (INS) DNA. We performed multiple linear regressions with adjustments for age, sex, race, BMI, and smoking status. Compared to HIV- controls, HIV+ participants off ART exhibited similar beta cell function and insulin sensitivity, without increases in markers of beta cell stress or death. Specifically, in HIV+ participants with CD4 counts <350 cells/μL, PI:C ratios were lower than in HIV- controls (p<0.01), suggesting a reduction in intrinsic beta cell stress among this group. By contrast, HIV+ participants on ART had higher fasting glucose (p<0.0001) and lower HOMA%B (p<0.001) compared to HIV- controls. Among the entire HIV+ population, higher HIV RNA correlated with lower fasting glucose (r = -0.57, p<0.001), higher HOMA%B (r = 0.40, p = 0.001), and lower PI:C ratios (r = -0.42, p<0.001), whereas higher CD4 counts correlated with higher PI:C ratios (r = 0.2, p = 0.00499). Our results suggest that HIV seropositivity in the absence of ART does not worsen beta cell function or glucose homeostasis, but immune reconstitution with ART may be associated with worsened beta cell function.

HIV and myocarditis

PURPOSE OF REVIEW

The purpose of this article is to review the literature on HIV and myocarditis and HIV-associated heart failure.

RECENT FINDINGS

Currently, 17 million people are receiving antiretroviral therapy (ART) globally. There is a decrease in mortality from HIV in the last decade with increased survival in those receiving ART. HIV-associated cardiac failure is on the increase, with more cases of diastolic dysfunction reported in the ART era. The pathophysiology of HIV-associated myocarditis is multifactorial. Cardiovascular magnetic resonance (CMR), through tissue characterization, demonstrates increased native T1 values which reflect both increased myocardial inflammation and fibrosis in HIV infection.

SUMMARY

HIV-associated myocarditis is common and may be an important cause of HIV-associated cardiac failure. CMR is an important imaging modality for the study of myocardial inflammation.

Balanced Caloric Restriction Minimizes Changes Caused by Aging on the Colonic Myenteric Plexus

Aging can promote significant morphofunctional changes in the gastrointestinal tract (GIT). Regulation of GIT motility is mainly controlled by the myenteric neurons of the enteric nervous system. Actions that aim at decreasing the aging effects in the GIT include those related to diet, with caloric restriction (CR). The CR is achieved by controlling the amount of food or by manipulating the components of the diet. Therefore, the objective of this study was to evaluate different levels of CR on the plasticity of nicotinamide adenine dinucleotide phosphate- (NADPH-) reactive myenteric neurons in the colon of Wistar rats during the aging process using ultrastructural (transmission electron microscopy) and morphoquantitative analysis. Wistar male rats (Rattus norvegicus) were distributed into 4 groups (n = 10/group): C, 6-month-old animals; SR, 18-month-old animals fed a normal diet; CRI, 18-month-old animals fed a 12% CR diet; CRII, 18-month-old animals fed a 31% CR diet. At 6 months of age, animals were transferred to the laboratory animal facility, where they remained until 18 months of age. Animals of the CRI and CRII groups were submitted to CR for 6 months. In the ultrastructural analysis, a disorganization of the periganglionar matrix with the aging was observed, and this characteristic was not observed in the animals that received hypocaloric diet. It was observed that the restriction of 12.5% and 31% of calories in the diet minimized the increase in density and cell profile of the reactive NADPH neurons, increased with age. This type of diet may be adapted against gastrointestinal disturbances that commonly affect aging individuals.

Chronic Kidney Disease in Persons Living with HIV: A Systematic Review

The purpose of our systematic review of research on chronic kidney disease (CKD) in persons living with HIV (PLWH) was to (a) compare and contrast diagnostic criteria for CKD, (b) identify risk factors of CKD in PLWH, and (c) elucidate the prevalence of CKD in PLWH. Keyword searches of PubMed and PsycInfo databases were followed by manual searches of references from 2000 through 2016; 21 studies met inclusion criteria. Sample sizes ranged from 8 to 15,140, with a mean age of 50 years, and represented diverse ethnicities/races and countries of origin. Fourteen studies were cross-sectional, six were cohort studies, and one was a case study. Major risk factors were related to hypertension, diabetes, and age. Prevalence ranged from 2.3% to 53.3% across a variety of countries and patient populations. The wide range in prevalence may have been due to differences in risk factors for the sample populations.

Qualitative impact assessment of an educational workshop on primary care practitioner attitudes to NICE HIV testing guidelines

Background

In 2013, Public Health England piloted the ‘3Cs (chlamydia, contraception, condoms) and HIV (human immunodeficiency virus)’ educational intervention in 460 GP surgeries. The educational HIV workshop aimed to improve the ability and confidence of staff to offer HIV testing in line with national guidelines.

Aim

To qualitatively assess the impact of an educational workshop on GP staff’s attitudes to NICE HIV testing guidelines.

Design & setting

Qualitative interviews with GP staff across England before and after an educational HIV workshop.

Method

Thirty-two GP staff (15 before and 17 after educational HIV workshop) participated in interviews exploring their views and current practice of HIV testing. Interview transcripts were thematically analysed and examined, using the components of the theory of planned behaviour (TPB) and normalisation process theory (NPT) as a framework.

Results

GPs reported that the educational HIV workshop resulted in increased knowledge of, and confidence to offer, HIV tests based on indicator conditions. However, overall participants felt they needed additional HIV training around clinical care pathways for offering tests, giving positive HIV results, and current treatments and outcomes. Participants did not see a place for point-of-care testing in general practice.

Conclusion

Implementation of national HIV guidelines will require multiple educational sessions, especially to implement testing guidelines for indicator conditions in areas of low HIV prevalence. Additional role-play or discussions around scripts suggesting how to offer an HIV test may improve participants’ confidence and facilitate increased testing. Healthcare assistants (HCAs) may need specific training to ensure that they are skilled in offering HIV testing within new patient checks.

Role of Country of Birth, Testing Site, and Neighborhood Characteristics on Nonlinkage to HIV Care Among Latinos

The objective of this study was to estimate disparities in linkage to human immunodeficiency virus (HIV) care among Latinos by country/region of birth, HIV testing site, and neighborhood characteristics. A retrospective study was conducted using Florida HIV surveillance records of Latinos/Hispanics aged ≥13 diagnosed during 2014-2015. Linkage to HIV care was defined as a laboratory test (HIV viral load or CD4) within 3 months of HIV diagnosis. Multi-level Poisson regression models were used to estimate adjusted prevalence ratios (aPR) for nonlinkage to care. Of 2659 Latinos, 18.8% were not linked to care within 3 months. Compared with Latinos born in mainland United States, those born in Cuba [aPR 0.60, 95% confidence interval (CI) 0.47-0.76] and Puerto Rico (aPR 0.61, 95% CI 0.41-0.90) had a decreased prevalence of nonlinkage. Latinos diagnosed at blood banks (aPR 2.34, 95% CI 1.75-3.12), HIV case management and screening facilities (aPR 1.76, 95% CI 1.46-2.14), and hospitals (aPR 1.42, 95% CI 1.03-1.96) had an increased prevalence of nonlinkage compared with outpatient general, infectious disease, and tuberculosis/sexually transmitted diseases/family planning clinics. Latinos who resided in the lowest (aPR 1.57, 95% CI 1.19-2.07) and third lowest (aPR 1.33, 95% CI 1.01-1.76) quartiles of neighborhood socioeconomic status compared with the highest quartile were at increased prevalence. Latinos who resided in neighborhoods with <25% Latinos also had increased prevalence of nonlinkage (aPR 1.23, 95% CI 1.01-1.51). Testing site at diagnosis may be an important determinant of HIV care linkage among Latinos due to neighborhood or individual-level resources that determine location of HIV testing.

The 'COmorBidity in Relation to AIDS' (COBRA) cohort: Design, methods and participant characteristics

Background

Persons living with HIV on combination antiretroviral therapy (cART) may be at increased risk of the development of age-associated non-communicable comorbidities (AANCC) at relatively young age. It has therefore been hypothesised that such individuals, despite effective cART, may be prone to accelerated aging.

Objective

The COmorBidity in Relation to AIDS (COBRA) cohort study was designed to investigate the potential causal link between HIV and AANCC, amongst others, in a cohort of middle-aged individuals with HIV with sustained viral suppression on cART and otherwise comparable HIV-negative controls.

Methods

Longitudinal cohort study of HIV-positive subjects ≥45 years of age, with sustained HIV suppression on cART recruited from two large European HIV treatment centres and similarly-aged HIV-negative controls recruited from sexual health centres and targeted community groups. Both HIV-positive and HIV-negative subjects were assessed at study entry and again at follow-up after 2 years.

Results

Of the 134 HIV-positive individuals with a median (IQR) age of 56 (51, 62) years recruited, 93% were male, 88% of white ethnicity and 86% were men who have sex with men (MSM). Similarly, the 79 HIV-negative subjects had a median (IQR) age of 57 (52, 64) and 92% were male, 97% of white ethnicity and 80% were MSM.

Conclusions

The results from the COBRA study will be a significant resource to understand the link between HIV and AANCC and the pathogenic mechanisms underlying this link. COBRA will inform future development of novel prognostic tools for earlier diagnosis of AANCC and of novel interventions which, as an adjunct to cART, may prevent AANCC.

Individual-level characteristics associated with oral HIV test acceptability among Peruvian men who have sex with men and transgender women: a cross-sectional study

OBJECTIVES

Peruvian men who have sex with men (MSM) and transgender women (TGW) are highly vulnerable to HIV infection (HIV), but stigma, access issues and fear of venipuncture hamper testing. The oral HIV test-which uses oral fluids and provides results in 20 minutes-could reduce these barriers. The objective of this study was to determine the acceptability of the oral HIV test and the individual-level factors associated with its acceptability among MSM and TGW.

METHODS

We conducted a cross-sectional secondary analysis among Peruvian MSM and TGW attending a community-based health centre between February 2012 and February 2013 to determine the individual-level factors associated with oral HIV test acceptability.

RESULTS

Of 334 participants, 88% were MSM and 12% TGW. Overall, 85% of participants indicated their acceptability of the oral HIV test. Acceptability was higher in MSM than TGW (85.7% vs 80.0%) but this difference was not significant. Factors associated with acceptability in MSM were: tertiary or higher education (prevalence ratio (PR)=1.18, 95% CI 1.06 to 1.32 and PR=1.16, 95% CI 1.03 to 1.30, respectively); sex with drug use (PR=1.19, 95% CI 1.05 to 1.36); believing that HIV is transmitted by saliva (PR=1.20, 95% CI 1.08 to 1.33); and potential use of the oral test at home (PR=1.56, 95% CI 1.32 to 1.85). The only factor associated with lower acceptability was having had first anal intercourse between 14 and 19 years of age (PR=0.89, 95% CI 0.80 to 0.98).

CONCLUSIONS

We identified the individual factors associated with oral HIV test acceptability among Peruvian MSM and TGW. Expanded use of the oral HIV test to increase testing rates among Peruvian MSM and TGW is recommended.

The clinical effectiveness of individual behaviour change interventions to reduce risky sexual behaviour after a negative human immunodeficiency virus test in men who have sex with men: systematic and realist reviews and intervention development

BACKGROUND

Men who have sex with men (MSM) experience significant inequalities in health and well-being. They are the group in the UK at the highest risk of acquiring a human immunodeficiency virus (HIV) infection. Guidance relating to both HIV infection prevention, in general, and individual-level behaviour change interventions, in particular, is very limited.

OBJECTIVES

To conduct an evidence synthesis of the clinical effectiveness of behaviour change interventions to reduce risky sexual behaviour among MSM after a negative HIV infection test. To identify effective components within interventions in reducing HIV risk-related behaviours and develop a candidate intervention. To host expert events addressing the implementation and optimisation of a candidate intervention.

DATA SOURCES

All major electronic databases (British Education Index, BioMed Central, Cumulative Index to Nursing and Allied Health Literature, EMBASE, Educational Resource Index and Abstracts, Health and Medical Complete, MEDLINE, PsycARTICLES, PsycINFO, PubMed and Social Science Citation Index) were searched between January 2000 and December 2014.

REVIEW METHODS

A systematic review of the clinical effectiveness of individual behaviour change interventions was conducted. Interventions were examined using the behaviour change technique (BCT) taxonomy, theory coding assessment, mode of delivery and proximity to HIV infection testing. Data were summarised in narrative review and, when appropriate, meta-analysis was carried out. Supplemental analyses for the development of the candidate intervention focused on post hoc realist review method, the assessment of the sequential delivery and content of intervention components, and the social and historical context of primary studies. Expert panels reviewed the candidate intervention for issues of implementation and optimisation.

RESULTS

Overall, trials included in this review (n = 10) demonstrated that individual-level behaviour change interventions are effective in reducing key HIV infection risk-related behaviours. However, there was considerable clinical and methodological heterogeneity among the trials. Exploratory meta-analysis showed a statistically significant reduction in behaviours associated with high risk of HIV transmission (risk ratio 0.75, 95% confidence interval 0.62 to 0.91). Additional stratified analyses suggested that effectiveness may be enhanced through face-to-face contact immediately after testing, and that theory-based content and BCTs drawn from 'goals and planning' and 'identity' groups are important. All evidence collated in the review was synthesised to develop a candidate intervention. Experts highlighted overall acceptability of the intervention and outlined key ways that the candidate intervention could be optimised to enhance UK implementation.

LIMITATIONS

There was a limited number of primary studies. All were from outside the UK and were subject to considerable clinical, methodological and statistical heterogeneity. The findings of the meta-analysis must therefore be treated with caution. The lack of detailed intervention manuals limited the assessment of intervention content, delivery and fidelity.

CONCLUSIONS

Evidence regarding the effectiveness of behaviour change interventions suggests that they are effective in changing behaviour associated with HIV transmission. Exploratory stratified meta-analyses suggested that interventions should be delivered face to face and immediately after testing. There are uncertainties around the generalisability of these findings to the UK setting. However, UK experts found the intervention acceptable and provided ways of optimising the candidate intervention.

FUTURE WORK

There is a need for well-designed, UK-based trials of individual behaviour change interventions that clearly articulate intervention content and demonstrate intervention fidelity.

Intestinal Barrier Impairment and Immune Activation in HIV-Infected Advanced Late Presenters are Not Dependent on CD4 Recovery

Damage of the mucosal barrier in HIV infection, microbial translocation, and immune activation can persist even in patients on successful antiretroviral therapy (ART) especially advanced late presenters. The aim of this study was to find factors that determine immune activation and bacterial translocation in HIV-infected advanced late presenters on suppressive ART. Forty-three late presenters (CD4 < 200 cells/µl prior to ART) on successful ART (more than 2 years of ART) with optimal and suboptimal CD4 recovery were enrolled into this study. The serum concentrations of intestinal fatty acid-binding peptide (I-FABP), zonulin-1, programmed cell death-1 protein (PCDP-1), and soluble (s)CD14 were measured using the ELISA test. We found higher serum levels of I-FABP and sCD14 in successfully antiretroviral-treated advanced late presenters compared to healthy subjects (p < 0.0001 and p = 0.0004). The serum concentration of PCDP-1 and zonulin-1 in HIV-infected patients did not differ from healthy controls. The levels of microbial translocation and immune activation markers were not associated with the degree of CD4 recovery. A serum concentration of I-FABP above 2.03 ng/ml was independently associated with a shorter ART (OR 0.78; p = 0.03). Older age was related to serum levels of sCD14 above 2.35 µg/ml (OR 1.1; p = 0.01). Higher serum levels of I-FABP and sCD14 in successfully antiretroviral-treated advanced late presenters compared to healthy subjects suggest an incomplete reconstruction of the intestinal barrier and sustained immune activation despite good CD4 recovery. It was not the CD4 level, but the length of the suppressive ART that was found to be associated with the restoration of the intestinal barrier.

Trends in discharges from the HIV/AIDS ward at a tertiary Canadian Hospital from 2005 to 2014

Advances in HIV therapies have transformed HIV infection into a manageable chronic disease. Accordingly, hospital admission trends among people living with HIV may have evolved over time. This study describes discharge diagnoses from the dedicated HIV/AIDS ward at St. Paul's Hospital in Vancouver, Canada. A retrospective database review of admissions to the HIV/AIDS ward between 1 July 2005 and 30 June 2014 was conducted. Primary discharge diagnoses were manually categorized by condition and reviewed by two physicians. Data were analysed in 12-month intervals. Trends were fitted using generalized estimating equations. A total of 1595 individuals with 3919 admissions were included. The median age was 46 years, 77.1% identified as male, 63.6% had a history of injection drug use (IDU) and 61.8% had a history of hepatitis C virus exposure. The most common reasons for admission included non-opportunistic respiratory tract infections (18.2%), cellulitis (7.3%), gastroenteritis (6.0%), endocarditis/bacteremia (4.9%) and bone/joint infections (3.5%). The proportion of admissions attributable to opportunistic infections declined from 16.2% in 2005 to 5.5% in 2014. Over this period, the proportion of individuals on antiretroviral therapy and with virologic suppression increased (odds ratio 1.19 [95% confidence interval 1.16, 1.23] and 1.22 [95% confidence interval 1.17, 1.26], respectively). These results demonstrate a decline in admissions related to opportunistic infections but increased admissions due to other infections among people living with HIV. Preventive and outpatient care for respiratory infections and complications of IDU may further improve health care outcomes and decrease hospital admissions in this setting.

Plasma soluble factor following two decades prolonged suppressive antiretroviral therapy in HIV-1-positive males: A cross-sectional study

Acute human immunodeficiency virus (HIV) infection is associated with a marked induction of several pathways that are linked to inflammation and CD4 T-cell depletion. Many of these processes do not fully resolve on short-term combination antiretroviral therapy (cART) (<5 years), despite complete and durable suppression of viremia. The effects of long-term (>15 years) successful antiretroviral therapy (ART) and the linkage between levels of biomarkers remain unclear. Therefore, the present study aims to assess the host plasma proteome in a well-defined clinical material from HIV-1-positive male patients on successful long-term ART (>15 years) and compared them with age-matched healthy controls and treatment-naïve male patients with viremia in a cross-sectional manner.Plasma samples were obtained from 3 categories of age-matched HIV-1-positive male patients on long-term successfully (ART, n = 10) with a median (Interquartile range, IQR) of 19 (17-20) years, treatment-naïve patients with viremia (VP, n = 14), and HIV-1-negative persons (HC, n = 11). Plasma proteome was analyzed using the proximity extension assay targeting 92 factors. Statistical analyses were performed with GraphPad Prism v7, R-packages, and Qlucore Omics Explorer v3.2. Functional enrichment analysis was performed by Kyoto Encyclopedia of Genes and Genomes (KEGG), and interactions of specific molecules were identified using Path Designer integrated into Ingenuity Pathway Analysis (IPA).Group wise comparison identified 53 soluble factors, which differed between the groups (P < .05). Cluster analysis identified 13 discrete soluble factors (CD8A, CRTAM, CXCL13, EGF, CD5, CD40, CXCL9, Gal-1, IL12RB1, KLRD1, PD-1, CASP-8 and TNFRSF9) between the studied groups (adjusted P < .001). The long-term successfully ART-treated individuals clustered and networked with the HC while VPs clustered separately. All of the proinflammatory cytokines and chemokines were normalized back to levels of healthy controls in long-term successfully ART-treated individuals, but not the levels of KLRD1 and PGDFB.sKLRD1 that is involved in the regulation of natural killer cell (NK) mediated cytotoxicity, failed to be restored to the level of HIV-negative individuals despite successful long-term ART. Additional analysis of NK cells along with T-cell subsets can provide insights into the long-term effects of ART on the immune system.

Racial/Ethnic Disparities in Failure to Initiate HIV Care: Role of HIV Testing Site, Individual Factors, and Neighborhood Factors, Florida, 2014-2015

Delayed initiation of human immunodeficiency virus (HIV) care affects disease progression. To determine the role of HIV testing site and neighborhood- and individual-level factors in racial/ethnic disparities in initiation of care, we examined Florida population-based HIV/AIDS surveillance system records. We performed multilevel Poisson regression to calculate adjusted prevalence ratios (APR) for non-initiation of care by race/ethnicity adjusting for HIV testing site type and individual- and neighborhood-level characteristics. Of 8,913 people diagnosed with HIV during 2014-2015 in the final dataset, 18.3% were not in care within three months of diagnosis. The APR for non-initiation of care for non-Hispanic Blacks relative to non-Hispanic Whites was 1.57 (95% confidence interval [CI] 1.38-1.78) and for those tested in plasma/donation centers relative to outpatient clinics was 2.45 (95% CI 2.19-2.74). Testing site and individual variables contribute to racial/ethnic disparities in non-initiation of HIV care. Linkage procedures, particularly at plasma/blood donation centers, warrant improvement.

Effectiveness of Systematic Periodontal Treatment in Male HIV-Infected Patients after 9 Years: A Case Series

OBJECTIVE

To investigate effectiveness of systematic periodontal treatment in the long term in HIV-infected patients undergoing highly active antiretroviral treatment.

METHODS

Longitudinal, prospective, open-label case series over a period of nine years. Periodontal treatment was performed by scaling and root planing and supportive periodontal care (SPC) at regular intervals. To measure effectiveness, reductions of pocket probing depths were defined as primary study endpoint.

RESULTS

During the study period, there was a proportional increase in periodontal pockets ≥4 mm of +53% and in pockets ≥ 6 mm of +100%. Mean pocket depth reductions on patient's level were, however, 0.4 mm nine years after scaling and root planing and supportive periodontal care (p=0.180). No teeth were lost during the observation period.

CONCLUSIONS

In terms of best evidence available, it is concluded that systematic periodontal treatment including SPC is effective in virologically controlled HIV infection and can be performed in dental practice safely.

Life expectancy and years of life lost in HIV patients under the care of BandarAbbas Behavioral Disorders Counseling Center

Background:

HIV epidemic is mostly targeted adults and has numerous negative health, social, economic, cultural and political consequences. In this study Life Expectancy (LE) and Average Years of Life Lost (AYLL) in HIV/AIDS patients are estimated.

Materials and Methods:

In this descriptive study all the patients at the age of 18 and more under the care of BandarAbbas Behavioral Disorders Counseling Center (BBDCC) during 2005-2015 are included. The town of BandarAbbas is center of Hormozgan Province in southern Iran. LE and AYLL have been estimated based on Life Table.

Results:

One hundred thirty four of the 426 eligible patients died during the study period. Compared to the general population LE for HIV/AIDS patients at age 20 is 46 years less in comparison with the general population of BandarAbbas. Moreover, a total of 8839 years of life lost during 2005-2015.

Conclusion:

LE in HIV/AIDS patients is less than LE among BandarAbbas general population and AYLL among them is more than general population. Most of the years of life lost are preventable if the health care system seriously will implement programs to control HIV/AIDS.

Management of Hepatitis C/HIV Coinfection in the Era of Highly Effective Hepatitis C Virus Direct-Acting Antiviral Therapy

The increased life expectancy of persons infected with human immunodeficiency virus (HIV) treated with antiretroviral therapy (ART) has resulted in renewed attention to non-HIV-related diseases exacerbated by HIV infection. Coinfection with hepatitis C virus (HCV) is a particular area of concern, as the global prevalence has been estimated at 2.5-5 million people. In this article, we discuss the epidemiology of HCV infection and reinfection, HCV-related liver disease progression in the era of effective ART, and the efficacy of emerging HCV treatment strategies in persons with HIV/HCV coinfection. New data regarding treatment of persons with HIV/HCV coinfection suggest that HCV treatment should be a priority in those with HIV. Results from recent studies using all-oral HCV regimens have shown high rates of sustained virologic response in both clinical trials and real-world settings. A multidisciplinary approach to HCV treatment in those with HIV is recommended for optimal patient management. Following HCV cure, practitioners also need to be mindful of the risks for HCV reinfection and educate patients on protective measures.
