Abstract
Background: Female sex workers (FSWs) and long distance truck drivers (LDTDs) are considered key populations at high risk for HIV transmission due to high prevalence. The intersection of these mobile populations presents unique challenges in the fight against HIV and the movement towards reducing new infections. Objective: The purpose of this study was to explore the nature of sex trade along a particular transport route. Sexual transactions and the vulnerabilities that exist between these two groups with regards to HIV/AIDS are described, with the purpose of furthering the agenda for targeted interventions. Methods: Qualitative in-depth interviews were conducted with 14 participants, seven FSWs and seven LDTDs. We recruited FSWs through snowballing, and LDTDs through intercepts at truck stops. Semi-structured interview guides were used for data collection, and thematic analysis was conducted. Results: The sex trade in this study is characterized by competition, fuelled by money-driven and age-disparate rivalry. Despite widespread HIV knowledge, FSWs contend with persistent challenges regarding condom use negotiation, induced by more money in the exchange for unsafe sex. Despite the placement of wellness centres in truck stops along the highway, LDTDs face stigma related challenges with regards to testing for HIV and personal acknowledgement of their involvement in the sex trade. Conclusion: The nature of the sex trade along the highway continues to be risky despite the availability of HIV testing and antiretroviral treatment (ART). The sex trade is perceived to be increasing along trucking routes, in spite of measures instituted to limit access to FSWs. FSWs struggle to cope with the pressure of unprotected sex because of the need to generate more income, as well as avoid incidents of violence and threats. Interventions along transport routes need to be inclusive of FSWs who could play a vital role in stigma reduction amongst LDTDs through peer education.

Abstract
OBJECTIVES HIV infection has become a chronic disease requiring long-term treatment. Premature cardiovascular disease resulting from atherosclerosis in the HIV-infected population has been observed. We assessed the prevalence of peripheral artery disease (PAD), a common consequence of atherosclerosis, in HIV-infected patients aged ≥ 50 years receiving antiretroviral treatment (ART). METHODS This cross-sectional study was conducted in 12 community hospitals in Chiang Mai, Thailand. Inclusion criteria were as follows: (1) age ≥ 50 years, (2) positive HIV status, and (3) currently receiving ART. Age- and sex-matched hospital patients without documented HIV infection were enrolled as a comparison group. Clinical data were extracted from hospital records. Personal information and details of PAD-related symptoms were obtained through face-to-face interviews. The diagnosis of PAD was made using ankle-brachial index (ABI) measurement. RESULTS Seven hundred and twenty-four participants were enrolled in the study (362 HIV-infected patients and 362 patients in the comparison group). In the HIV-infected group, 43% were male; the mean (± standard deviation) age was 57.8 ± 5.6 years. The mean (± standard deviation) times from HIV diagnosis and ART initiation were 10.0 ± 4.3 and 8.6 ± 3.5 years, respectively. The prevalence of abnormal ABI (< 1.00) was significantly lower in the HIV-infected group than in the comparison group (20 versus 27%, respectively; P = 0.03), while that of PAD (ABI ≤ 0.90) was not significantly different between the two groups (5 and 7%, respectively). In the HIV-infected group, female sex and low body mass index were independently associated with abnormal ABI. CONCLUSIONS The prevalence of PAD when measured by ABI in HIV-infected older adults was relatively low. A follow-up study to determine the incidence of PAD and its persistence with time is warranted.

Abstract
BACKGROUND Hepatitis B (HBV)-HIV coinfection is associated with liver inflammation, which can progress to liver fibrosis/cirrhosis and hepatocellular carcinoma. We determined HBV seroprevalence in children and adolescents participating in the TREAT Asia Pediatric HIV Observational Database. METHODS A multisite cross-sectional study was conducted in HIV-infected patients currently <25 years old receiving antiretroviral treatment (ART) who had HBV surface antigen (HBsAg), or HBV surface antibody (anti-HBs) or HBV core antibody (anti-HBc) tested during 2012-2013. HBV coinfection was defined as having either a positive HBsAg test or being anti-HBc positive and anti-HBs negative, reflective of past HBV infection. HBV seroprotection was defined as having a positive anti-HBs test. RESULTS A total of 3380 patients from 6 countries (Vietnam, Thailand, Cambodia, Malaysia, Indonesia and India) were included. The current median (interquartile range) age was 11.2 (7.8-15.1) years. Of the 2755 patients (81.5%) with HBsAg testing, 130 (4.7%) were positive. Of 1558 (46%) with anti-HBc testing, 77 (4.9%) were positive. Thirteen of 1037 patients with all 3 tests were anti-HBc positive and HBsAg and anti-HBs negative. One child was positive for anti-HBc and negative for anti-HBs but did not have HBsAg tested. The prevalence of HBV coinfection was 144/2759 (5.2%) (95% confidence interval: 4.4-6.1). Of 1093 patients (32%) with anti-HBs testing, 257 (23.5%; confidence interval: 21.0-26.0) had positive tests representing HBV seroprotection. CONCLUSIONS The estimated prevalence of HBV coinfection in this cohort of Asian HIV-infected children and adolescents on ART was 5.2%. The majority of children and adolescents tested in this cohort (76.5%) did not have protective HBV antibody. The finding supports HBV screening of HIV-infected children and adolescents to guide revaccination, the use of ART with anti-HBV activity and future monitoring.

Abstract
The global rollout of Antiretroviral Treatment (ART) has revealed an urgent need to understand the medicines-taking practices of HIV-positive adolescents. In the last decade, the literature on the social determinants of health has broadened the evidence-base on ART adherence. Interdisciplinary studies have expanded conceptions of medicines-taking beyond clinical or health systems frameworks, recognising the importance of socio-structural conditions and of patients' beliefs and experiences. Participatory research techniques which foreground the perspectives of adolescents provide greater insights still into their adherence. This article explores the use of participatory methods within a broader study on the social determinants of ART adherence among HIV-positive adolescents in South Africa. We describe how participatory methods were incorporated into this study (n = 1,059 in the quantitative baseline). We focus on an exercise, 'Yummy or crummy?', that explored the multisensory dimensions of medicines-taking, including their colour, smell, shape, and delivery mechanism. We describe two principal findings: first, adolescents' preference for greater understanding of the chemical workings of medicines, manifested in their preferences for colour, taste and shape of medicines; and second, the vital relationship between sensory preferences and the social imperatives of discretion and confidentiality regarding HIV-status.

Abstract
INTRODUCTION Attitudes, responses, and reactions of HIV-positive women in three sub-Saharan African regions toward a therapeutic exercise intervention, aimed to determine the presence of depression and low body self-image, were captured. This provided insight into body satisfaction and desire to exercise (Stage 1, n=60), body self-image and depression (Stage 2, n=60), and overall concerns around the often adverse side effects of antiretroviral treatment (ART). A program of therapeutic (specialty) exercise was developed for the experimental design (Stage 2), to quantify the psychological side effects of these variables. METHODOLOGY Stage 1 constituted a qualitative exploration into attitudes and perceptions around ART, toxicity, health concerns, metabolic irregularities (lipodystrophy), body shape and size dissatisfaction, and cultural attitudes toward exercise. This stage deployed brief informal face-to-face interviews, based on the World Health Organization (WHO)/United Nations Fund for Population Activities (UNFPA) AIDS Inventory, in three sub-Saharan African regions (including provincial and district hospitals, nongovernmental organizations, voluntary counseling and testing/HIV and testing centers, and primary care outpatient clinics). Stage 2 of the study comprised a quantitative experimental design, conducted on a sample of HIV-positive women (mean age=39.0 years; mean years on ART=5.5; 86% black) in three selected HIV outpatient clinics in Johannesburg, South Africa. DATA ANALYSIS The collated data sets from both stages of the research were presented, analyzed, and interpreted (thematic analyses [Stage 1] and statistical analyses [Stage 2]) using the body self-image questionnaire and Beck's depression inventory. RESULTS Stage 1 outlined participants' concerns and reports around 1) body shape and size, including long-term effects of ART and 2) attitudes toward exercise, as a function of HIV status. Stage 2 represented pre- and posttest statistics, showing low statistical means for both the experiment and the control groups, with statistical significance for four out of nine items of subscales of body self-image questionnaire.

Abstract
Outcomes of HIV-infected children have improved dramatically over the past decade, but are undermined by patient loss to follow-up (LTFU). We assessed patterns of LTFU among HIV-infected children receiving antiretroviral treatment (ART) at a large inner-city HIV clinic in Johannesburg, South Africa between 2005 and 2014.Demographic and clinical data were extracted from clinic records of children under 12 years. Differences between characteristics of children retained in care and LTFU were assessed using Wilcoxon rank sum tests or Pearson χ tests. Cox proportional hazard models then identified characteristics associated with LTFU.Of 135 children, the median age at ART initiation was 21.5 months (IQR: 6.3-47.7) with a median follow-up time of 3.3 years (IQR: 1.4-5.0). The incidence rate of LTFU was 10.8 per 100 person-years (95% CI: 8.2-14.4); cumulatively 36% of children were LTFU. Almost a third (n = 39) of children missed a clinic visit, but then returned to care; 77% of these were eventually LTFU. In total, 18% of children had elevated viral loads after 6 or more months of ART. Older age at ART initiation (18-59 months: aHR 1.6, 95% CI: 3.9-14.2) and ever missing a clinic visit (aHR 7.4 95% CI: 3.9-14.2) were independent predictors of LTFU.High rates of LTFU were observed in this primary care clinic. Risks for LTFU included older age (>18 months old) and missed clinic visits. Identifying children who miss scheduled visits and developing strategies directed at retaining them in care is critical to improving long-term pediatric HIV outcomes.

Abstract
SMS reminders sent to personal mobiles are increasingly used by clinical services to promote patient engagement, including adherence to antiretroviral treatment (ART) for HIV. From August to September 2015, a 6-week, randomised SMS reminder for ART adherence intervention was implemented among 98 HIV-positive clients of Australian's largest HIV charitable organisation located in Sydney. This was followed by a mixed-method evaluation, comprising a self-completed online survey and a one-to-one interview. Of the 62 survey participants, all being men, the majority were gay (85.5%) and living long-term with HIV (median year of HIV diagnosis = 1998). While everyone was on ART, a substantial proportion (n = 27, 43.5%) had interrupted treatment in the past. At the end of the intervention, based on the standard SMAQ measure, 82% had consistently adhered to ART in the previous week. While there was no statistically significant intervention effect, perceiving less stigma were independently associated with better ART adherence (adjusted odds ratio = 0.37; 95% CI 0.16-0.89; P = .026). Of the 11 interviewees, despite limited add-on effects on individual ART adherence, the campaign was well-received as a unique community support service. This study underscores the essential role of empowerment through enhancing disease self-management, increasing social support and reducing stigma, particularly for long-term HIV survivors. SMS messaging, part of mHealth, delivered by community services could have broader impacts on reducing health and social inequity.

Abstract
INTRODUCTION Darunavir (DRV) was the last approved protease inhibitor (PI) and has been extensively used for the treatment of HIV in both naïve and experienced subjects due to its high genetic barrier and efficacy. The introduction in clinical practice of integrase strand transfer inhibitors limited its role in the management of naïve subjects and in antiretroviral treatment simplification strategies. However, recent data from trials that have investigated the new DRV/cobicistat/emtricitabine/tenofovir alafenamide (D/C/F/TAF) combination showed an excellent efficacy and tolerability of this coformulation both in naïve patients and in those with viral suppression, making D/C/F/TAF a new option for the treatment of HIV infection. Areas covered: The authors present and discuss the efficacy and safety data of DRV when used in antiretroviral-naïve, multiexperienced subjects and in the setting of treatment deintensification in subjects with viral suppression. Moreover, the authors evaluate the recent data from two different Phase III trials on D/C/F/TAF both in treatment-naïve and virologically suppressed subjects. Expert opinion: Although novel antiretroviral drugs may become available over time, DRV continues to represent a valuable option for multiexperienced subjects and has a role in simplification regimens. In addition, the convenience of D/C/F/TAF coformulation may be useful for the future management of HIV-infected subjects.

Abstract
Background There are several regimens for starting antiretroviral treatment, but it remains unknown whether either of them is more advantageous regarding the time course and magnitude of human immunodeficiency virus (HIV) RNA decay in semen. Objective To evaluate the differential effect of different antiretroviral drug families on viral kinetics in seminal plasma (SP) of treatment-naive HIV-infected patients. Methods Phase II, randomized, open-label study in which participants were randomized 1:1:1 to receive tenofovir-disoproxil fumarate (DF) plus emtricitabine, and either cobicistat-boosted elvitegravir (EVGcobi), rilpivirine (RPV), or ritonavir-boosted darunavir (DRVrtv). The primary endpoint was the proportion of participants with undetectable HIV-RNA in SP at week 12. HIV type 1 (HIV-1) RNA was measured in paired SP and blood plasma (BP) at baseline and after 1, 2, 4, 6, 8, 12, 18, and 24 weeks. Elvitegravir (EVG), RPV, and darunavir (DRV) concentrations were quantified by the liquid chromatography-tandem mass spectrometry method. Results In SP, the HIV-RNA decay rate with RPV was as fast as with EVGcobi; by week 12, all participants in the RPV and the EVGcobi groups reached an undetectable viral load but only 58.3% in the DRVrtv arm (P = .003). The highest SP/BP drug concentration ratio was for EVG (0.43), followed-up by RPV (0.19), and DRV (0.10). For both EVG and RPV, the SP concentrations exceeded >2-fold the protein binding-adjusted EC90 for wild-type HIV-1; for DRV, only 33.7% of the SP showed concentrations above the protein binding-adjusted EC90. Conclusions In SP, both RPV and EVGcobi, associated to tenofovir-DF and emtricitabine, behave similarly and achieve an undetectable viral load much faster than DRVrtv.

Sexual Risk Behaviors of Patients with HIV/AIDS over the Course of Antiretroviral Treatment in Northern Vietnam. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2018; 15:ijerph15061106. [PMID: 29844289 PMCID: PMC6025123 DOI: 10.3390/ijerph15061106] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/19/2018] [Revised: 05/25/2018] [Accepted: 05/26/2018] [Indexed: 01/18/2023]
Abstract
Antiretroviral therapy (ART) improves the health and well-being of people living with the human immunodeficiency virus (HIV, PLWH), and reduces their risk of transmitting the virus to sexual partners. However, patterns of sexual risk behavior among HIV-positive patients taking ART in Vietnam remain largely unknown. In this study, we sought to examine sexual risk behaviors and their associated factors among HIV-positive patients receiving ART in northern Vietnam. The socio-demographic characteristics, ART use, health status, and sexual behaviors of 1133 patients taking ART in the Hanoi and Nam Dinh provinces were explored through face-to-face interviews. There were 63.5% of patients who had one sex partner, while 3.6% and 5.6% of patients had sexual intercourse with casual partners or sex workers, respectively, in the previous 12 months. Most participants tended to use condoms more often with commercial sex partners (90.2%) and intimate partners (79.7%), and less often with casual partners (60.9%). Higher age (odds ratio, OR = 1.0; 95% CIs = 1.0, 1.1) or suffering pain/discomfort (OR = 1.7; 95% CIs = 1.2, 2.4) were factors more likely to be associated with multiple sex partners. Patients who were self-employed were more likely to have sexual intercourse with casual partners/sex workers (OR = 2.1; 95% CIs = 1.1, 4.0). Meanwhile, a higher score on the EuroQol visual analog scale (EQ-VAS), an unknown HIV stage, and a longer duration of ART were adversely associated with not using condoms with casual partners/sex workers. Patients with longer durations of ART had a lower likelihood of not using a condom with casual partners/sex workers (OR = 0.5; 95% CIs = 0.3, 0.8). Our study underscored a relatively high rate of unsafe sexual behaviors among HIV-positive patients. Continuing to improve the physical and psychological well-being of HIV-positive patients in Vietnam is important in reducing the spread of HIV via risky sexual behaviors. In addition, safe-sex education should be provided to older people, and to those who are self-employed.

Abstract
Background Transmitted drug resistance (TDR) may compromise response to antiretroviral therapy (ART). However, there are limited data on TDR patterns and impacts among people who use illicit drugs (PWUD). Methods Data were drawn from 2 prospective cohorts of PWUD in Vancouver, Canada. We characterized patterns of TDR among human immunodeficiency virus (HIV)-infected PWUD, and assessed its impacts on first-line ART virological outcomes. Results Between 1996 and 2015, among 573 ART-naive PWUD (18% with recent HIV infection), the overall TDR prevalence was 9.8% (95% confidence interval [CI], 7.3%-12.2%), with an increasing trend over time, from 8.5% in 1996-1999 to 21.1% in 2010-2015 (P = .003), mainly driven by resistance to nonnucleoside reverse transcriptase inhibitors (NNRTIs). TDR-associated mutations were more common for NNRTIs (5.4%), followed by nucleoside reverse transcriptase inhibitors (3.0%) and protease inhibitors (1.9%). TDR prevalence was lower among recently infected PWUD (adjusted odds ratio, 0.39 [95% CI, .15-.87]). Participants with TDR had higher risk of virological failure than those without TDR (log-rank P = .037) in the first year of ART. Conclusions Between 1996 and 2015, TDR prevalence increased significantly among PWUD in Vancouver. Higher risk of virological failure among PWUD with TDR may be explained by some inappropriate ART prescribing, as well as undetected minority resistant variants in participants with chronic HIV infection. Our findings support baseline resistance testing early in the course of HIV infection to guide ART selection among PWUD in our setting.

Abstract
Background Nutritional care is considered a crucial component of comprehensive care for people living with HIV/AIDS (PLWHA), particularly in resource-limited settings where malnutrition and food insecurity are endemic problems, and low quality monotonous diets are the norm. The findings of this study provide baseline information on dietary diversity and related factors for health care providers so that they will be able to improve nutritional care and support activity. Therefore, the aim of this study was to assess dietary diversity and associated factors among HIV positive adults (18-65 years old) attending antiretroviral therapy (ART) clinics at Hiwot Fana and Dilchora Hospitals, eastern Ethiopia. Patients and methods An institution-based cross-sectional study was conducted from November 2015 to February 2016 at the ART clinics of Hiwot Fana and Dilchora Hospitals. Using a systematic random sampling technique, a total of 303 patients were selected from all adults attending the ART clinics. The data were collected with a 95% CI used to show association between dietary diversity and independent factors. Results A total of 303 adult HIV positive individuals on ART participated in the study and 62.4% were females. The largest numbers of participants (49.5%) were 30-40 years of age. Eighty-seven (28.7%) participants had low dietary diversity (≤4 food groups). Duration of anti-retroviral treatment was the factor significantly associated with dietary diversity: respondents with a duration of antiretroviral treatment of more than 2 years were almost two times more likely to have high dietary diversity compared with those with less than a year of antiretroviral treatment (adjusted odds ratio =0.490; 95% CI: 0.091, 0.978). Conclusion Low dietary diversity was found to be a nutritional problem among HIV positive adults. Duration of antiretroviral treatment was the predictor of low dietary diversity. Therefore, appropriate dietary management of side effects of ART is important.

Abstract
Although eligibility for antiretroviral treatment is no longer based on CD4 thresholds, CD4 testing remains important. Variation in CD4 cell count complicates initiation of antibiotic prophylaxis, differential diagnoses and assessments of immunological recovery. Five hundred and fifty-three HIV-positive antiretroviral-naïve adults, recruited from inner-city clinics, had three serial CD4 cell count tests. Test 1 was mostly done in a laboratory network supporting primary care clinics, while Tests 2 and 3 were performed in a tertiary-level laboratory. Reproducibility was assessed through Bland-Altman limits of agreement and coefficients of variation. Participants, a mean age of 34 years and mostly female (57%), had a median 203 CD4 cells/μL (Test 1). Seventeen per cent classified as having advanced HIV disease (CD4 cell count < 200 cells/µL) on Test 1 had a CD4 cell count > 200 cells/µL on Tests 2 and 3. Mean differences between tests were <10 cells/µL for all comparisons. Limits of agreement for Tests 1 and 2 were -106.9 to 112.7 and coefficient of variation 15. Corresponding figures for Tests 2 and 3 were -88.2 to 103.4, and 13. Means of tests were similar, suggesting no systematic measurement differences, despite testing being done at different times. Variations were, however, considerable in many instances, though smaller in testing done in the same laboratory. CD4 cut-offs must not be applied rigidly, but rather constitute one amongst many factors used to guide patient care. Moreover, given the difficulties in determining whether CD4 changes are due to HIV disease, or other biological and laboratory factors, CD4 laboratory reports should include a range of plausible values, not only the absolute count.

Abstract
HIV transmission within stable heterosexual HIV serodiscordant couples accounts for almost half the new incident infections in South Africa and Uganda. Advances in HIV prevention provide opportunities to reduce transmission risk within serodiscordant partnerships (e.g., antiretroviral treatment (ART), pre-exposure prophylaxis (PrEP), medical male circumcision, and couples-based HIV counselling and testing). These interventions require a clinical encounter with a provider who recognises prevention opportunities within these partnerships. We explored healthcare provider understanding of HIV serodiscordance in a reproductive counselling study with providers in eThekwini district, South Africa, and Mbarara district, Uganda. In eThekwini, in-depth interviews (29) and focus group discussions (2) were conducted with 42 providers (counsellors, nurses and doctors) from public sector clinics. In Mbarara, in-depth interviews were conducted with 38 providers (medical officers, clinical officers, nurses, peer counsellors and village health workers). Thematic analysis was conducted using NVivo software. In eThekwini, many providers assumed HIV seroconcordance among client partners and had difficulty articulating how serodiscordance occurs. Mbarara providers had a better understanding of HIV serodiscordance. In the two countries, providers who understood HIV serodiscordance were better able to describe useful HIV-prevention strategies. Healthcare providers require training and support to better understand the prevalence and mechanisms of HIV serodiscordance to implement HIV-prevention strategies for HIV serodiscordant couples.

Abstract
The aim of this study was to identify sociodemographic factors associated with attrition in the 3 steps of the HIV continuum of care related to the 90-90-90 targets - access to diagnosis, treatment initiation, and virologic suppression, in Brazilian adults (15 years or older), in 2016.Programmatic data were obtained from 2 information systems from the Brazilian Ministry of Health, which register all antiretroviral therapy (ART) dispensations and all CD4 and viral load counts (VL) performed within the country's public health system. The 3 attrition indicators were late presentation to care, defined as a first CD4 count <350 cells/mm among ART-naive individuals who performed a first CD4 count in 2016; not being on ART, defined as having no recorded dispensation within the last 100 days of the year, among those who were linked to care in 2016; and not being virologically suppressed, defined as having the last recorded VL >200 copies/mL in 2016, among those with a recorded VL count who were on treatment for at least 6 months. Association of sociodemographic factors with these indicators was analyzed by unconditional logistic regression analysis.Lower educational level and black/brown/indigenous race/color were associated with worse outcomes in the 3 indicators. Environmental indicators, namely the region, size, and social vulnerability index of the municipality of residence, also played an important role in the models. Younger age was strongly associated with not being on ART and not showing virological suppression.Our findings help identify the barriers in the different stages of the HIV continuum of care, which need to be addressed in order to progress toward the achievement of the 90-90-90 targets.

Abstract
BACKGROUND Multiple studies have identified a relationship between the complexity of a medication regimen and non-adherence. However, most studies in people who live with HIV (PLWH) have focused on antiretroviral use and have failed to consider the impact of other medications. OBJECTIVE The aim of our study is to identify the Medication Regimen Complexity Index (MRCI) as an associated factor for nonadherence to antiretroviral treatment (ART). The secondary aim is to analyze the relationship between clinical and pharmacotherapeutical variables and adherence to antiretroviral treatment and to generate an adherence model. METHODS A transversal, observational study. Patients included were PLWH over 18 years of age on active antiretroviral therapy. Patients who participated in clinical trials or who did not meet the inclusion criteria were excluded. We had studied HIV transmission mode, viral load, treatment status, number of comorbidities and complexity index as factors associated with adherence to ART. RESULTS We included 619 patients in the study. Number of comorbidities ( p = 0.021; OR = 1.038-1.570); viral load ( p = 0.023; OR = 1.108-4.505) and MRCI ( p < 0.001; OR = 1.138-1.262) (ART and concomitant treatment) were the independent associated factors to ART nonadherence. The value of the Hosmer and Lemeshow test confirmed the validity of this model (P = 0.333). CONCLUSION A higher MRCI was associated with non-adherence. Therefore, the regimen complexity calculation may be appropriate in daily practice for identifying patients at a higher risk of becoming non-adherent.

Navigating Multiple Sources of Healing in the Context of HIV/AIDS and Wide Availability of Antiretroviral Treatment: A Qualitative Study of Community Participants' Perceptions and Experiences in Rural South Africa. Front Public Health 2018; 6:73.

Abstract
BACKGROUND South Africa introduced the world's largest antiretroviral treatment (ART) program in 2004 and since 2016 the Department of Health implemented a universal Treatment as Prevention (TasP) strategy. However, some studies have shown that increasing the availability of ART is insufficient for the comprehensive treatment of HIV, since many people still use traditional health practitioners (THPs) to avoid being identified as HIV positive, and for reasons unrelated to HIV/AIDS. This qualitative study explored the factors influencing how both HIV-negative and HIV-positive people choose amongst multiple sources of healing and how they engage with them, in the context of HIV/AIDS and wide availability of ART. METHODS Data were collected as part of a larger TasP trial at the Africa Health Research Institute, KwaZulu-Natal. Repeat in-depth individual interviews were conducted with 10 participants. Repeat group discussions were conducted with 42 participants. Group discussion data were triangulated using community walks and photo-voice techniques to give more insight into the perceptions of community members. All data were collected over 18 months. Thematic analysis was used to analyze participants' narratives from both individual interviews and group discussions. FINDINGS In the context of HIV/AIDS and wide availability of ART, use of biomedical and traditional healing systems seemed to be common in this locality. People used THPs to meet family expectations, particularly those of authoritative heads of households such as parents or grandparents. Most participants believed that THPs could address specific types of illnesses, especially those understood to be spiritually caused and which could not be addressed or cured by biomedical practitioners. However, it was not easy for participants to separate some spiritually caused illnesses from biological illnesses in the context of HIV/AIDS. These data demonstrate that in this context, the use of THPs continues regardless of the wide availability of ART. To meet the health care needs of those patients requiring a health care system which combines biomedical and traditional approaches, collaboration and integration of biomedical and traditional health care should be considered.

Abstract
Background The European AIDS Clinical Society (EACS) Guidelines have since 2005 provided multidisciplinary recommendations for the care of HIV‐positive persons in geographically diverse areas. Guideline highlights Major revisions have been made in all sections of the 2017 Guidelines: antiretroviral treatment (ART), comorbidities, coinfections and opportunistic diseases. Newly added are also a summary of the main changes made, and direct video links to the EACS online course on HIV Management. Recommendations on the clinical situations in which tenofovir alafenamide may be considered over tenofovir disoproxil fumarate are provided, and recommendations on which antiretrovirals can be used safely during pregnancy have been revised. Renal and bone toxicity and hepatitis C virus (HCV) treatment have been added as potential reasons for ART switches in fully virologically suppressed individuals, and dolutegravir/rilpivirine has been included as a treatment option. In contrast, dolutegravir monotherapy is not recommended. New recommendations on non‐alcoholic fatty liver disease, chronic lung disease, solid organ transplantation, and prescribing in elderly are included, and human papilloma virus (HPV) vaccination recommendations have been expanded. All drug–drug interaction tables have been updated and new tables are included. Treatment options for direct‐acting antivirals (DAAs) have been updated and include the latest combinations of sofosbuvir/velpatasvir/voxilaprevir and glecaprevir/pibrentasvir. Recommendations on management of DAA failure and acute HCV infection have been expanded. For treatment of tuberculosis (TB), it is underlined that intermittent treatment is contraindicated, and for resistant TB new data suggest that using a three‐drug combination may be as effective as a five‐drug regimen, and may reduce treatment duration from 18‐24 to 6‐10 months. Conclusions Version 9.0 of the EACS Guidelines provides a holistic approach to HIV care and is translated into the six most commonly spoken languages.

Abstract
PURPOSE Little information is available on patients on antiretroviral treatment (ART) after a long-term period from sub-Saharan Africa, with the longest follow-up and related outcomes being after 10 years on ART. At the Infectious Diseases Institute (IDI) (Kampala, Uganda), we set up a cohort of patients already on ART for 10 years at the time of enrolment, who will be followed up for additional 10 years. PARTICIPANTS A prospective observational cohort of 1000 adult patients previously on ART for 10 years was enrolled between May 2014 and September 2015. Patients were eligible for enrolment if they were in their consecutive 10th year of ART regardless of the combination of drugs for both first- and second-line ART. Data were collected at enrolment and all annual study visits. Follow-up visits are scheduled once a year for 10 years. Biological samples (packed cells, plasma and serum) are stored at enrolment and follow-up visits. FINDINGS TO DATE Out of 1000 patients enrolled, 345 (34.5%) originate from a pre-existing research cohort at IDI, while 655 (65.5%) were enrolled from the routine clinic. Overall, 81% of the patients were on first line at the time of the enrolment in the ART long-term cohort, with the more frequent regimen being zidovudine plus lamivudine plus nevirapine (44% of the cohort), followed by zidovudine plus lamivudine plus efavirenz (22%) and tenofovir plus lamivudine or emtricitabine plus efavirenz (10%). At cohort enrolment, viral suppression was defined as HIV-RNA <400 copies/mL was 95.8%. FUTURE PLANS Through collaboration with other institutions, we are planning several substudies, including the evaluation of the risk for cardiovascular diseases, the assessment of bone mineral density, screening for liver cirrhosis using fibroscan technology and investigation of drug-drug interactions between ART and common drugs used for non-communicable diseases.

Abstract
Introduction: The number of HIV-infected children and adolescents requiring second-line antiretroviral treatment (ART) is increasing in low- and middle-income countries (LMIC). However, the effectiveness of paediatric second-line ART and potential risk factors for virologic failure are poorly characterized. We performed an aggregate analysis of second-line ART outcomes for children and assessed the need for paediatric third-line ART. Methods: We performed a multicentre analysis by systematically reviewing the literature to identify cohorts of children and adolescents receiving second-line ART in LMIC, contacting the corresponding study groups and including patient-level data on virologic and clinical outcomes. Kaplan–Meier survival estimates and Cox proportional hazard models were used to describe cumulative rates and predictors of virologic failure. Virologic failure was defined as two consecutive viral load measurements >1000 copies/ml after at least six months of second-line treatment. Results: We included 12 cohorts representing 928 children on second-line protease inhibitor (PI)-based ART in 14 countries in Asia and sub-Saharan Africa. After 24 months, 16.4% (95% confidence interval (CI): 13.9–19.4) of children experienced virologic failure. Adolescents (10–18 years) had failure rates of 14.5 (95% CI 11.9–17.6) per 100 person-years compared to 4.5 (95% CI 3.4–5.8) for younger children (3–9 years). Risk factors for virologic failure were adolescence (adjusted hazard ratio [aHR] 3.93, p < 0.001) and short duration of first-line ART before treatment switch (aHR 0.64 and 0.53, p = 0.008, for 24–48 months and >48 months, respectively, compared to <24 months). Conclusions: In LMIC, paediatric PI-based second-line ART was associated with relatively low virologic failure rates. However, adolescents showed exceptionally poor virologic outcomes in LMIC, and optimizing their HIV care requires urgent attention. In addition, 16% of children and adolescents failed PI-based treatment and will require integrase inhibitors to construct salvage regimens. These drugs are currently not available in LMIC.

Abstract
INTRODUCTION Significant progress has been made with respect to the initiation of children on antiretroviral therapy (ART) in Southern Africa including Swaziland, however retention of these children in care poses a major challenge. The aim of the study was to assess retention to care in children testing HIV positive taking into account the number of return child welfare care (CWC) visits the child made. METHODS A retrospective cross sectional study and was conducted at 4 facilities in Swaziland. All children who were HIV infected from 0 to 18 months were identified using the child welfare register (CWC). Infant characteristics were obtained from the child welfare register and early infant diagnosis logbooks. Proportion of patients retained in care were calculated at three, six, nine and twelve months. RESULTS Of the 32 HIV positive children identified tested between December 2014 up to July 2016, sixty eight percent (n = 22) of the children that tested HIV positive were retained at three months, 40.6% at six months, 18.8% at nine months and 12.5% at twelve months. Children that resided in urban areas, more male than female children, children from mothers who were on antiretroviral treatment, children initiated on antiretroviral treatment, mothers on antiretroviral treatment for more than one year and children who received Infant Nevirapine were more likely to be retained. CONCLUSION Facilities are performing well in terms of identifying HIV positive children within the first two months of life and linking them into care. However, as time progresses the retention of children in care declines. Innovative strategies need to be developed to enhance patient retention.

Abstract
HIV infection is responsible for one the most devastating human pandemics. The advent of antiretroviral therapy has changed the course of the pandemic and saved millions of lives. Complex therapeutic regimens have been introduced since 1996 and have contributed to the transformation of HIV infection into a treatable chronic diseases. New types of potent antiretrovirals and their combinations, including “once daily” treatment, have simplified the regimens and diminished side effects. Nevertheless the adherence to antiretroviral therapy remains unsatisfactory and varies between 27 and 80% across different population in various studies, compared with the required level of 95%. The lack of adherence to antiretroviral therapy is a multi-factorial and dynamic process which raises considerable difficulties for long-term follow-up. Current solutions to this problem are complex. These should be applied by a multidisciplinary team and should take into account key features related to both the individual and social factors as well as to the population to whom it belongs (children, teenagers, elderly, marginalized population like drug users, incarcerated patients, sex workers, etc.). Importantly, adherence should continue to be monitored even in patients known to be compliant. In case of subsequent failure the team should identify the reasons for non-adherence and apply the appropriate methods. Where usual methods have no chance of success, a coordinated package of services also known as “harm reduction” can be offered in order to reduce the risks of transmission. The current article analyses the concept of adherence to antiretroviral therapy, the shortcomings of this medication and the methods that can be applied in practice to increase adherence. Emphasis is placed on the analysis of groups at high risk for HIV infection that currently represent the spearhead with which the HIV pandemic is spreading.

Abstract
Introduction: Modern combined antiretroviral therapies (cART) allow to effectively suppress HIV-1 viral load, with the 90% virologic success rate, meeting the WHO target in most clinical settings. The aim of this study was to analyse antiretroviral treatment efficacy in Poland and to identify variables associated with virologic suppression. Methods: Cross-sectional data on 5152 (56.92% of the countrywide treated at the time-point of analysis) patients on cART for more than six months with at least one HIV-RNA measurement in 2016 were collected from 14 Polish centres. Patients’ characteristics and treatment type-based outcomes were analysed for the virologic suppression thresholds of <50 and <200 HIV-RNA copies/ml. CART was categorized into two nucleos(t)ide (2NRTI) plus non-nucleoside reverse transcriptase (NNRTI) inhibitors, 2NRTI plus protease (PI) inhibitor, 2NRTI plus integrase (InI) inhibitor, nucleos(t)ide sparing PI/r+InI and three drug class regimens. For statistics Chi-square and U-Mann Whitney tests and adjusted multivariate logistic regression models were used. Results: Virologic suppression rates of <50 copies/mL were observed in 4672 (90.68%) and <200 copies/mL in 4934 (95.77%) individuals. In univariate analyses, for the suppression threshold <50 copies/mL higher efficacy was noted for 2NRTI+NNRTI-based combinations (94.73%) compared to 2NRTI+PI (89.93%), 2NRTI+InI (90.61%), nucleos(t)ide sparing PI/r+InI (82.02%) and three drug class regimens (74.49%) (p < 0.0001), with less pronounced but significant differences for the threshold of 200 copies/mL [2NRTI+NNRTI-97.61%, 2NRTI+PI-95.27%, 2NRTI+InI-96.61%, PI/r+InI- 95.51% and 86.22% for three drug class cART) (p < 0.0001). However, in multivariate model, virologic efficacy for viral load <50 copies/mL was similar across treatment groups with significant influence by history of AIDS [OR:1.48 (95%CI:1.01–2.17) if AIDS diagnosed, p = 0.046], viral load < 5 log copies/mL at care entry [OR:1.47 (95%CI:1.08–2.01), p = 0.016], baseline lymphocyte CD4 count ≥200 cells/µL [OR:1.72 (95%CI:1.04–2.78), p = 0.034] and negative HCV serology [OR:1.97 (95%CI:1.29–2.94), p = 0.002]. For viral load threshold <200 copies/mL higher likelihood of virologic success was only associated with baseline lymphocyte CD4 count ≥200 cells/µL [OR:2.08 (95%CI:1.01–4.35), p = 0.049] and negative HCV status [OR:2.84 (95%CI:1.52–5.26), p = 0.001]. Conclusions: Proportion of virologically suppressed patients is in line with WHO treatment target confirming successful application of antiretroviral treatment strategy in Poland. Virological suppression rates depend on baseline patient characteristics, which should guide individualized antiretroviral tre0atment decisions.

Abstract
Introduction: Chronic immune activation due to ongoing HIV replication may lead to impaired immune responses against opportunistic infections such as tuberculosis (TB). We studied the role of HIV replication as a risk factor for incident TB after starting antiretroviral therapy (ART). Methods: We included all HIV-positive adult patients (≥16 years) in care between 2000 and 2014 at three ART programmes in South Africa. Patients with previous TB were excluded. Missing CD4 cell counts and HIV-RNA viral loads at ART start (baseline) and during follow-up were imputed. We used parametric survival models to assess TB incidence (pulmonary and extrapulmonary) by CD4 cell and HIV-RNA levels, and estimated the rate ratios for TB by including age, sex, baseline viral loads, CD4 cell counts, and WHO clinical stage in the model. We also used Poisson general additive regression models with time-updated CD4 and HIV-RNA values, adjusting for age and sex. Results: We included 44,260 patients with a median follow-up time of 2.7 years (interquartile range [IQR] 1.0–5.0); 3,819 incident TB cases were recorded (8.6%). At baseline, the median age was 34 years (IQR 28–41); 30,675 patients (69.3%) were female. The median CD4 cell count was 156 cells/µL (IQR 79–229) and the median HIV-RNA viral load 58,000 copies/mL (IQR 6,000–240,000). Overall TB incidence was 26.2/1,000 person-years (95% confidence interval [CI] 25.3–27.0). Compared to the lowest viral load category (0–999 copies/mL), the adjusted rate ratio for TB was 1.41 (95% CI 1.15–1.75, p < 0.001) in the highest group (>10,000 copies/mL). Time-updated analyses for CD4/HIV-RNA confirmed the association of viral load with the risk for TB. Conclusions: Our results indicate that ongoing HIV replication is an important risk factor for TB, regardless of CD4 cell counts, and underline the importance of early ART start and retention on ART.

Abstract
STUDY QUESTION Are the reproductive outcomes of HIV-infected donor oocyte recipient women comparable to those of non-infected women? SUMMARY ANSWER HIV-infected women have lower clinical pregnancy and live birth rates than non-infected women. WHAT IS ALREADY KNOWN The literature on the effect of HIV infection on reproductive outcome is scarce at best; the only report to date comparing oocyte donation cycles in HIV-infected women versus non-infected controls found no differences in pregnancy rates between the two groups. However, this study was performed nearly a decade ago and did not evaluate the effect of immuno-virological characteristics of oocyte recipients or the HIV antiretroviral therapy effect. STUDY DESIGN SIZE, AND DURATION This is a matched-cohort study including 514 oocyte donation cycles, 257 from HIV-infected women and 257 non-infected controls, performed between April 2004 and November 2014. PARTICIPANTS/MATERIALS, SETTING, AND METHOD Each cycle of an HIV-infected woman (n = 257) was matched with a cycle of a non-infected woman (1:1). Biochemical pregnancy, clinical pregnancy, ongoing pregnancy and live birth in the two groups were compared using a multivariate logistic regression analysis. The effect of antiretroviral treatment options on pregnancy outcomes of HIV-infected women was analyzed using a logistic regression model adjusted for time elapsed from diagnosis, and CD4 levels and viral load prior to embryo transfer. MAIN RESULTS AND THE ROLE OF CHANCE Cycles of HIV-infected patients receiving oocyte donation presented lower pregnancy and live birth rates than matched non-infected controls. Treatment options and infection parameters analyzed do not seem to affect the reproductive results in HIV-infected women. The variable most influencing pregnancy outcomes was the number of transferred embryos; lower pregnancy rates were obtained after single embryo transfer. LIMITATIONS REASONS FOR CAUTION Patients with HIV infection have specific health issues, such as infection/treatment side effects, which makes it impossible to find a matching control group of non-infected patients for these variables. WIDER IMPLICATIONS OF THE FINDINGS HIV-infected women receiving donated oocytes present lower pregnancy rates when compared to non-infected controls, regardless of the antiretroviral treatment followed. The complexity of the treatments (both in medication types and combinations) makes it difficult to define whether any one treatment option is better than the others in terms of pregnancy outcomes in oocyte recipients.
