Failure to prescribe pneumocystis prophylaxis is associated with increased mortality, even in the cART era: results from the Treat Asia HIV observational database

Childhood and adolescent factors shaping vulnerability to underage entry into sex work: a quantitative hierarchical analysis of female sex workers in Nairobi, Kenya

OBJECTIVE

To explore factors associated with early age at entry into sex work, among a cohort of female sex workers (FSWs) in Nairobi, Kenya.

BACKGROUND

Younger age at sex work initiation increases the risk of HIV acquisition, condom non-use, violence victimisation and alcohol and/or substance use problems. This study aimed to understand factors in childhood and adolescence that shape the vulnerability to underage sex work initiation.

DESIGN

Building on previous qualitative research with this cohort, analysis of behavioural-biological cross-sectional data using hierarchical logistic regression.

PARTICIPANTS AND MEASURES

FSWs aged 18-45 years were randomly selected from seven Sex Workers Outreach Programme clinics in Nairobi, and between June and December 2019, completed a baseline behavioural-biological survey. Measurement tools included WHO Adverse Childhood Experiences, Alcohol, Smoking and Substance Involvement Screening Test and questionnaires on sociodemographic information, sexual risk behaviours and gender-based violence. Descriptive statistics and logistic regression were conducted using hierarchical modelling.

RESULTS

Of the 1003 FSWs who participated in the baseline survey (response rate 96%), 176 (17.5%) initiated sex work while underage (<18 years). In the multivariable analysis, factors associated with entering sex work while underage included incomplete secondary school education (aOR=2.82; 95% CI=1.69 to 4.73), experiencing homelessness as a child (aOR=2.20; 95% CI=1.39 to 3.48), experiencing childhood physical or sexual violence (aOR=1.85; 95% CI=1.09 to 3.15), young age of sexual debut (≤15 years) (aOR=5.03; 95% CI=1.83 to 13.79) and being childless at time of sex work initiation (aOR=9.80; 95% CI=3.60 to 26.66).

CONCLUSIONS

Lower education level and childhood homelessness, combined with sexual violence and sexual risk behaviours in childhood, create pathways to underage initiation into sex work. Interventions designed for girls and young women at these pivotal points in their lives could help prevent underage sex work initiation and their associated health, social and economic consequences.

Managing motherhood - the experiences of female sex workers in Nairobi, Kenya

Women selling sex often face challenges in raising their children in the context of significant socio-economic difficulties and the social stigma inherent in sex work. This paper is based on a cross-sectional qualitative study that explored the dual roles of motherhood and sex work among female sex workers enrolled for ongoing HIV prevention and treatment services in the Sex Workers Outreach Programme (SWOP) clinics in Nairobi, Kenya. We examined women's experiences and coping in negotiating and managing the dual roles of motherhood and sex work. In-depth interviews were conducted with 39 women randomly selected from 1,000 women included in a baseline behavioural-biological survey conducted in October-November 2020 as part of the Maisha Fiti study. The analysis focused on themes related to motherhood and making a living: (i) entry into sex work; (ii) childcare arrangements; (iii) ensuring respectability for their children; and (iv) pursuit of safety and security. Findings from the study show women's entry into sex work was necessitated by poverty and a lack of reliable sources of livelihood to support their children. While performing their motherhood roles, the women demonstrate agency in navigating through their stigmatised conflicted sex work role to be able to provide for their children.

Survival of patients living with HIV and cancer in Cali, Colombia

Background

People living with HIV have an increased risk of cancer compared to the general population. However, with the increase in life expectancy and advances in antiretroviral therapy, the survival of patients with cancer and HIV has changed.

Objective

To determine the survival of patients living with HIV and cancer in Cali, Colombia.

Methods

A retrospective cohort study was conducted at the Fundación Valle del Lili, Cali, Colombia. Data from the HIV database was crossed with data from the hospital and population-based cancer registries between 2011-2019. Patients <18 years, limited available clinical information on the diagnosis and treatment of HIV and cancer, and non-oncological tumor diagnosis were excluded.

Results

A total of 173 patients were included. The frequencies of AIDS-defining neoplasms were: Non-Hodgkin lymphoma (42.8%), Kaposi sarcoma (27.8%), and cervical cancer (4.6%). Overall survival was 76.4% (95% CI 68.9-82.3) at five years. Poorer survival was found in patients with AIDS-defining infections (56.9% vs. 77.8%, p=0.027) and non-AIDS-defining infections (57.8% vs. 84.2%, p=0.013), while there was better survival in patients who received antiretroviral therapy (65.9% vs. 17.9%, p=0.021) and oncological treatment (66.7% vs. 35.4%, p<0.001). The presence of non-AIDS-defining infections increases the risk of dying (HR = 2.39, 95% CI 1.05-5.46, p=0.038), while oncological treatment decreases it (HR = 0.33, 95% CI 0.14-0.80, p=0.014).

Conclusions

In people living with HIV, Non-Hodgkin lymphoma and Kaposi sarcoma are the most common neoplasms. Factors such as AIDS-associated and non-AIDS-associated infections have been identified as determinants of survival. Cancer treatment seems to improve survival.

Characteristics and Prognostic Factors of Non-HIV Immunocompromised Patients With Pneumocystis Pneumonia Diagnosed by Metagenomics Next-Generation Sequencing

Objective

The aim of this study was to evaluate the potential of metagenomic next-generation sequencing (mNGS) for the diagnosis of pneumocystis pneumonia (PCP) in patients with non-human immunodeficiency virus-infection and to discuss the clinical characteristics and identify prognostic factors associated with patients with non-HIV PCP.

Methods

Forty-six patients with PCP who were admitted in respiratory intensive care unit (ICU) between May 2018 and May 2020 were retrospectively reviewed. The subjects were divided into survivor and non-survivor groups according to the patients' outcome. Conventional methods and mNGS for detecting Pneumocystis jirovecii (P. jirovecii) were analyzed. The patients' demographics, comorbidities, laboratory parameters, and treatments were compared and evaluated in both groups to identify risk factors for mortality by using univariate and multivariate logistic regression.

Results

Metagenomic next-generation sequencing (mNGS) showed a satisfying diagnostic performance of 100% positive of detecting P. jirovecii from bronchoalveolar lavage (BAL) specimens in forty-six patients with non-HIV PCP, compared to only 15.2% for Gomori Methenamine silver (GMS) staining and 84.8% for Serum 1,3-beta-D-glucan (BDG). Among them, the mean age was 46.4-year-old (range 18–79-year-old) and mortality rate was 43.5%. The dominant underlying conditions were connective tissue diseases (34.8%), autoimmune kidney diseases (30.4%), followed by hematologic malignancies (10.9%), and solid organ transplantation (6.5%). A total of 38 cases (82.6%) received glucocorticoid and 19 cases (41.3%) used immunosuppressant within 3 months before diagnosed PCP. Multiple infections were very common, over two thirds' cases had mixed infections. Compared with survivors, non-survivors had a higher acute physiology and chronic health evaluation II (APACHE II) score (14.4 ± 4.8 vs. 10 ± 3.4), Procalcitonin (PCT) [ng/ml: 0.737 (0.122–1.6) vs. 0.23 (0.095–0.35)], lactic dehydrogenase (LDH) [U/L: 1372 (825.5–2150) vs. 739 (490.5–956)], and neutrophil-lymphocyte ratio (NLR) [21.6 (15.67–38.2) vs. 11.75 (5.1–15.52)], but had a lower PaO₂/FiO₂ ratio (mmHg:108.8 ± 42.4 vs. 150.5 ± 47.5), lymphocytes [×10⁹/L: 0.33 (0.135–0.615) vs. 0.69 (0.325–1.07)] and CD4+ T cells [cell/μl: 112 (53.5–264) vs. 255 (145–303.5)], all P < 0.05. Furthermore, we found non-survivors' PaO₂/FiO₂ ratio of day 3 and day 7 had not improved when compared with that of day one, and platelet level and NLR became worse. Multivariate analysis showed that other pathogens' co-infection (OR = 9.011, 95% CI was 1.052–77.161, P = 0.045) and NLR (OR = 1.283, 95% CI was 1.046–1.547, P = 0.017) were the independent risk factors of poor prognosis.

Conclusion

mNGS is a very sensitive diagnostic tool for identifying P. jirovecii in patients who are non-HIV immunocompromised. PCP in patients who are non-HIV infected is associated with a high rate of multiple infections and severe condition. Mixed infection and elevation of NLR were the independent risk factors of poor prognosis.

Effect of Rifabutin in Dolutegravir Dosing: A Case Series

Background: Tuberculosis (TB) is the leading cause of death in human immunodeficiency virus (HIV)-infected people worldwide. Currently there are no studies examining the use of Rifabutin (RBN) and Dolutegravir (DTG) in co-infected persons. This is a case series of 4 co-infected patients receiving both agents who underwent Pharmacokinetic (PK) analysis. Methods and Results: This is a retrospective chart review study of four patients diagnosed with both HIV and TB, receiving RBN and DTG and undergoing therapeutic drug monitoring. All 4 cases had lower than expected DTG concentrations at least once, including those on the current recommended dose of DTG with RBN, and even those receiving higher doses. Conclusions: Given the frequency of low DTG and RBN concentrations, therapeutic drug monitoring (TDM) for these drugs is advisable. Prospective clinical studies are needed to further determine the PK interactions between RBN and DTG, and virologic response to treatment.

When Coffee Collapsed: An Economic History of HIV in Uganda

In some Ugandan fishing communities, almost half the population lives with HIV. Researchers designate these communities "HIV hotspots" and attribute disproportionate disease burdens to "sex-for-fish" relationships endemic to the lakeshores. In this article, we trace the emergence of Uganda's HIV hotspots to structural adjustment. We show how global economic policies negotiated in the 1990s precipitated the collapse of Uganda's coffee sector, causing mass economic dislocation among women workers, who migrated to the lake. There, they entered overt forms of sex work or marriages they may have otherwise avoided, intimate economic arrangements that helped to "engineer the spread of HIV," as one respondent recounted.

'You just prefer to die early!': how socioecological context impedes treatment for people living with HIV in Iran

INTRODUCTION

Despite the low prevalence of HIV and broad provision of antiretroviral therapy, the Middle East and North Africa (MENA) remains the only region where new HIV infections and AIDS-related deaths are not declining. There is a dearth of evidence from MENA on antiretroviral therapy engagement. In this qualitative study, we sought to identify the ways in which successful treatment is hindered in Iran, which is home to 24% of HIV infections in MENA.

METHODS

From August 2018 to January 2019, we used purposive sampling and conducted 12 individual interviews and 8 focus group discussions with 27 female and 31 male patients, in addition to 5 individual interviews with HIV care providers and 1 focus group discussion with 8 care providers. Social constructivism augmented with realist-informed thematic analysis was used to understand how the socioecological context triggers cognitive and affective mechanisms that disrupt antiretroviral therapy.

RESULTS

The use of Thematic Network Analysis resulted in the identification of three key cognitive and affective mechanisms that appear to shape treatment experience and are triggered via HIV's socioecological context and changing economic conditions in Iran: denial in response to societal negative perceptions of HIV; fear in response to societal lack of awareness regarding HIV and misinformation; and despair in response to HIV-related stigma and enacted discrimination, economic insecurity and social support.

CONCLUSIONS

To our knowledge, this is the first study within MENA to identify pathways through which successful treatment is hindered. It appears that lack of societal awareness regarding HIV is specific to low prevalence settings, such as MENA countries, where negative perceptions, stigma, discrimination and misinformation regarding HIV and its treatment produce denial, fear and despair, acting as mechanisms that disrupt antiretroviral therapy. The experience of despair, in response to changing economic conditions and social support, further impacts treatment experience.

Intersections of financial agency, gender dynamics, and HIV risk: A qualitative study with adolescent girls and young women in Zambia

Objectives: Recent research demonstrates that economic interventions may positively effect HIV risk among adolescent girls and young women (AGYW) in sub-Saharan Africa. Some evidence reveals potential associations between financial decision-making and bargaining power in sexual relationships. However, this evidence is mixed, nuanced, and limited. This paper explores how AGYW in Zambia understand financial agency and its effect on intimate relationships. Methods: In-depth qualitative interviews were conducted with 30 females aged 15-24 years residing in Kalingalinga, a low income, high-density residential area in Lusaka. Data were analysed using thematic content analysis. Results: Participants spoke of the ability to earn and spend money as reality for some and aspirational for many others, intrinsic to cultural and religious caveats influencing perceptions of agency for women. The transfer of financial independence to sexual agency within relationships was viewed as a mechanism for HIV risk reduction; however, male sexual privilege was an obstacle irrespective of financial decision-making. Conclusions: Programmes aiming to enhance financial agency for AGYW have the potential to reduce HIV sexual risk. Yet, to be most effective, integration with gender-transformative programmes is needed to address norms of male dominance that keep AGYW in positions of vulnerability.

Mobility study of young women who exchange sex for money or commodities using Google Maps and qualitative methods in Kampala, Uganda

OBJECTIVES

We aimed to assess mobility patterns and reasons for high mobility among young women engaged in sex work within a randomised controlled trial to gauge how mobility may hinder access to health services and enhance HIV risk in a highly vulnerable population.

SETTING

Participants were recruited from a clinic in Kampala, Uganda set up for women at high risk of HIV infection.

PARTICIPANTS

Adolescent girls and young women engaged in sex for money and/or commodities are at particular risk in countries with high HIV prevalence and high fertility rates. High mobility increases exposure to HIV risk. Women participants were eligible for the parent study if aged 15-24 years, HIV negative and engaged in sex work. For this substudy, 34 qualitative interviews were held with 14 sex workers (6 HIV positive, 8 HIV negative), 6 health worker/policy makers, 3 peer educators, 5 'queen mothers' and 6 male partners MEASURES: Participants used Google Maps to identify work venues at 12-month and 18-month study visits. We also conducted 34 interviews on mobility with: high-risk women, male partners, health workers and sex-worker managers. Topics included: distance, frequency and reasons for mobility. We used Python software to analyse mapping data.

RESULTS

Interviews found in depth narratives describing lack of education and employment opportunities, violence, lack of agency, social, sexual and familial support networks and poverty as a complex web of reasons for high mobility among young sex workers.

CONCLUSIONS

Young women at high risk are highly mobile. Reasons for mobility impact access and retention to health services and research activities. Strategies to improve retention in care should be cognisant and tailored to suit mobility patterns.

Understanding the determinants and consequences of HIV status disclosure in Manicaland, Zimbabwe: cross-sectional and prospective analyses

Few longitudinal studies have measured trends and effects of disclosure over ART scale-up in general-population samples. We investigated levels, determinants and outcomes of disclosure to relatives and partners in a large general-population cohort in Zimbabwe. Trends in disclosure levels from 2003 to 2013 were analysed, and multivariable logistic regression was used to identify determinants. Longitudinal analyses were conducted testing associations between disclosure and prevention/treatment-related outcomes. Disclosure to anyone increased from 79% to 100% in men and from 63% to 98% in women from 2003 to 2008; but declined to 89% in both sexes in 2012-2013. More women than men disclosed to relatives (67.8% versus 44.4%; p < 0.001) but fewer women disclosed to partners (85.3% versus 95.0%; p < 0.001). In 2012-2013,secondary/higher education, being single, and experience of stigma were associated with disclosure to relatives in both sexes. Partner characteristics and HIV-group attendance were associated with disclosure to partners for women. Reactions to disclosure were generally supportive but less so for females than males disclosing to partners (92.0% versus 97.4%). Partner disclosure was weakly associated (p < 0.08) with having had a CD4 count or taken ART at follow-up in females. To conclude, this study shows disclosure is vital to HIV prevention and treatment, and programmes to facilitate disclosure should be re-invigorated.

Domestic stigmatisation: refocusing interventions for people living with HIV

Domestic stigmatisation serves as an umbrella term for acts of enacted or felt stigma experienced in a person's domestic environment. This article reports on the term which transpired from a narrative inquiry in 2011 with people living with HIV (PLWH) who reported humiliation or segregation, experienced or perceived, within the domestic environment that rendered the individual disabled, diseased, unworthy, unhealthy, or deficient. A literature review about this form of stigma was conducted using the following inclusion criteria: 1) a peer-reviewed source; 2) published between 2011 and 2018; 3) access to full-text articles; 4) accessible in English; 5) reported from any country; and 6) using qualitative or mixed-method approaches. A total of 37 studies were included in the review - documenting 51 specific experiences of domestic stigmatisation (referred to as acts for the purpose of the review) across all studies. A matrix was developed detailing each study's' publication date, geographical context, participant gender (where possible) and the reported acts. A critical analysis is offered on the concept "domestic stigmatisation" and its relevance to domestic or family interventions. Deliberate attention to this concept can potentially refocus HIV stigma-reducing interventions to benefit families and promote coping strategies to reduce stigma-related stress associated with seropositive identities.

The effects of the integration of an economic strengthening and HIV prevention education programme on the prevalence of sexually transmitted infections and savings behaviours among adolescents: a full-factorial randomised controlled trial in South Africa

Background

Multisectoral approaches are thought necessary to prevent HIV among adolescents. We examined whether an economic strengthening (ES) and an HIV-prevention education intervention improved outcomes when combined versus separately.

Methods

We conducted a full-factorial randomised controlled study to randomise participants into all possible intervention groups based on the two interventions: economic strengthening only (ES-only), HIV-prevention only (HIV-only), both interventions combined (ES+HIV) and no intervention (control). We measured sexually transmitted infections (STIs), self-reported economic and sexual behaviours/knowledge, and pregnancy at a pre-intervention and two post-intervention assessments. Eligible participants were adolescents 14 to 17 years old from a programme supporting vulnerable families in Gauteng Province, South Africa. We estimated intervention effects using repeated measures, generalised linear mixed models.

Results

A total of 1773 adolescents participated (57% female). ES+HIV adolescents had the lowest STI prevalence at first endline; however, the comparison with the control was not significant (OR 0.62, 95% CI 0.27 to 1.41). ES-only or HIV-only groups were not significantly better than the control on STI prevalence (OR 1.53, 95% CI 0.73 to 3.20 and OR 1.47, 95% CI 0.69 to 3.12, respectively). STI prevalence became more similar among the groups at second endline.ES-only adolescents were more likely to participate in savings groups (p=0.004) and plan to save for education (p=0.001) versus the control. ES+HIV adolescents were more likely to plan to save for education versus the control (p=0.001) and HIV-only groups (p=0.002) but did not differ significantly from the ES-only group (p=0.803). The ES+HIV intervention's effect on HIV knowledge was significant compared with the control (p=0.03) and ES-only groups (p<0.001), but not when compared with the HIV-only group (p=0.091). Effects on pregnancy, sexual behaviours or other economic behaviours were not significant.

Conclusions

We could not confirm the ES and HIV interventions, separately or combined, were effective to reduce STI prevalence. Evaluations of multicomponent interventions should use full-factorial designs to fully assess effects.

Barriers to HIV testing uptake among men in sub-Saharan Africa: a scoping review

Introduction: HIV testing among men remains low globally and in sub-Saharan Africa (SSA) in particular, when compared with their female counterparts. The aim of this study was to synthesise evidence on barriers to HIV testing among men in SSA using a scoping review method.Methods: A scoping review was conducted, guided by Arksey and O'Malley's framework. A search was made in PubMed, American Doctoral Dissertations via EBSCOhost, Union Catalogue of Theses and Dissertations and SA ePublications via SABINET Online and World Cat Dissertations, Theses via OCLC and Google Scholar. The PRISMA (preferred reporting items for systematic reviews and meta-analyses) chart was used to document the review process. The PRISMA extension for scoping reviews - PRISMA-ScR: checklist and explanation - was also used. The mixed method appraisal tool version 2018 was used to determine the methodological quality of the included studies. Thematic analyses were conducted using NVivo version 11.Results: Key barriers to HIV testing among men in SSA were knowledge of HIV, fear of testing positive for HIV, stigma associated with HIV, healthcare providers' services, confidentiality, and clinic setting.Conclusion: Structural and individual factors present barriers to HIV testing uptake among men in SSA. Community and home-based initiatives have the potential to improve the uptake of HIV testing among men in SSA, considering the confidentiality concerns posed by clinic settings.

A scoping review on the role of masculine norms in men's engagement in the HIV care continuum in sub-Saharan Africa

Men living with HIV/AIDS in sub-Saharan Africa are less likely than women to be engaged at each stage of the HIV care continuum. We conducted a scoping review in May of 2016 to identify how masculine norms influence men's HIV care engagement in sub-Saharan Africa. Our review yielded a total of 17 qualitative studies from 8 countries. Six major themes emerged that demonstrated how norms of masculinity create both barriers and facilitators to care engagement. Barriers included the exacerbating effects of masculinity on HIV stigma, the notion that HIV threatened men's physical strength, ability to provide, self-reliance, and risk behavior, and the belief that clinics are spaces for women. However, some men transformed their masculine identity and were motivated to engage in care if they recognized that antiretroviral therapy could restore their masculinity by rebuilding their strength. These findings demonstrate masculinity plays an important role in men's decision to pursue and remain in HIV care across sub-Saharan Africa. We discuss implications for tailoring HIV messaging and counseling to better engage men and an agenda for future research in this area.

The presence of Pneumocystis jirovecii DNA in plasma is associated with a higher mortality rate in patients with AIDS-associated Pneumocystis pneumonia

To examine the relationship between Pneumocystis jirovecii DNA (PJ-DNA) levels in blood from AIDS-associated Pneumocystis pneumonia (AIDS-PCP) and mortality, and to correlate mitochondrial large subunit rRNA (mtLSUrRNA) gene polymorphism with mortality, we performed a retrospective study including AIDS-PCP patients between 2014 and 2016 from one hospital in China. PJ-DNA in plasma was measured by nested polymerase chain reaction (PCR) of the mtLSUrRNA gene and in positive specimens we further detected the level of PJ-DNA using qPCR. Polymorphisms were observed at two positions (85 and 248) of the mtLSUrRNA gene by sequencing. The PJ-DNA positivity rate for survivors and nonsurvivors was 13.64% (9/66) and 78.57% (11/14) (P ≤ .001), respectively. Using multivariate analysis, we found that lactate dehydrogenase, PaO2, albumin and PJ-positive in blood were independent predictors of death (P = .011; P = .042; P = .01; P ≤ .001, respectively). The PJ-DNA level in the nonsurvivor group (n = 11) was higher than that of the survivor group (n = 9) (54610.3copies/ ml vs. 934.5 copies/ml, P = .006). Nine had genotype 1, and 88.89% (8/9) patients died. Of nine with genotype 3, 11.11% (1/9) died (P = .003). In conclusion, high PJ-DNA level detected by analyzing plasma and mtLSUrRNA genotype 1 are strongly associated with death in AIDS-PCP patients.

Agents of change among people living with HIV and their social networks: stepped-wedge randomised controlled trial of the NAMWEZA intervention in Dar es Salaam, Tanzania

INTRODUCTION

NAMWEZA is a novel intervention that focuses on preventing HIV and promoting sexual and reproductive health and rights by addressing underlying factors related to vulnerability of acquiring HIV, such as depression, intimate partner violence (IPV) and stigma. The goal of the study was to evaluate the effect of the NAMWEZA intervention on risk behaviour as well as factors potentially contributing to this vulnerability for people living with HIV and their network members.

METHODS

A stepped-wedge randomised controlled trial was conducted from November 2010 to January 2014 among people living with HIV and their network members in Dar es Salaam, Tanzania. 458 people living with HIV were randomised within age/sex-specific strata to participate in the NAMWEZA intervention at three points in time. In addition, 602 members of their social networks completed the baseline interview. Intention-to-treat analysis was performed, including primary outcomes of uptake of HIV services, self-efficacy, self-esteem, HIV risk behaviour and IPV.

RESULTS

For people living with HIV, a number of outcomes improved with the NAMWEZA intervention, including higher self-efficacy and related factors, as well as lower levels of depression and stigma. IPV reduced by 40% among women. Although reductions in HIV risk behaviour were not observed, an increase in access to HIV treatment was reported for network members (72% vs 94%, p=0.002).

CONCLUSION

These results demonstrate the complexity of behavioural interventions in reducing the vulnerability of acquiring HIV, since it is possible to observe a broad range of different outcomes. This study indicates the importance of formally evaluating interventions so that policymakers can build on evidence-based approaches to advance the effectiveness of HIV prevention interventions.

Cotrimoxazole prophylaxis decreases tuberculosis risk among Asian patients with HIV

INTRODUCTION

Cotrimoxazole (CTX) is recommended as prophylaxis against Pneumocystis jiroveci pneumonia, malaria and other serious bacterial infections in HIV-infected patients. Despite its in vitro activity against Mycobacterium tuberculosis, the effects of CTX preventive therapy on tuberculosis (TB) remain unclear.

METHODS

Adults living with HIV enrolled in a regional observational cohort in Asia who had initiated combination antiretroviral therapy (cART) were included in the analysis. Factors associated with new TB diagnoses after cohort entry and survival after cART initiation were analysed using Cox regression, stratified by site.

RESULTS

A total of 7355 patients from 12 countries enrolled into the cohort between 2003 and 2016 were included in the study. There were 368 reported cases of TB after cohort entry with an incidence rate of 0.99 per 100 person-years (/100 pys). Multivariate analyses adjusted for viral load (VL), CD4 count, body mass index (BMI) and cART duration showed that CTX reduced the hazard for new TB infection by 28% (HR 0.72, 95% CI l 0.56, 0.93). Mortality after cART initiation was 0.85/100 pys, with a median follow-up time of 4.63 years. Predictors of survival included age, female sex, hepatitis C co-infection, TB diagnosis, HIV VL, CD4 count and BMI.

CONCLUSIONS

CTX was associated with a reduction in the hazard for new TB infection but did not impact survival in our Asian cohort. The potential preventive effect of CTX against TB during periods of severe immunosuppression should be further explored.

'They care rudely!': resourcing and relational health system factors that influence retention in care for people living with HIV in Zambia

INTRODUCTION

Despite access to free antiretroviral therapy (ART), many HIV-positive Zambians disengage from HIV care. We sought to understand how Zambian health system 'hardware' (tangible components) and 'software' (work practices and behaviour) influenced decisions to disengage from care among 'lost-to-follow-up' patients traced by a larger study on their current health status.

METHODS

We purposively selected 12 facilities, from 4 provinces. Indepth interviews were conducted with 69 patients across four categories: engaged in HIV care, disengaged from care, transferred to another facility and next of kin if deceased. We also conducted 24 focus group discussions with 158 lay and professional healthcare workers (HCWs). These data were triangulated against two consecutive days of observation conducted in each facility. We conducted iterative multilevel analysis using inductive and deductive reasoning.

RESULTS

Health system 'hardware' factors influencing patients' disengagement included inadequate infrastructure to protect privacy; distance to health facilities which costs patients time and money; and chronic understaffing which increased wait times. Health system 'software' factors related to HCWs' work practices and clinical decisions, including delayed opening times, file mismanagement, drug rationing and inflexibility in visit schedules, increased wait times, number of clinic visits, and frustrated access to care. While patients considered HCWs as 'mentors' and trusted sources of information, many also described them as rude, tardy, careless with details and confidentiality, and favouring relatives. Nonetheless, unlike previously reported, many patients preferred ART over alternative treatment (eg, traditional medicine) for its perceived efficacy, cost-free availability and accompanying clinical monitoring.

CONCLUSION

Findings demonstrate the dynamic effect of health system 'hardware' and 'software' factors on decisions to disengage. Our findings suggest a need for improved: physical resourcing and structuring of HIV services, preservice and inservice HCWs and management training and mentorship programmes to encourage HCWs to provide 'patient-centered' care and exercise 'flexibility' to meet patients' varying needs and circumstances.

Hazardous alcohol consumption and alcohol-related problems are associated with unknown and HIV-positive status in fishing communities in Uganda

In Uganda, alcohol consumption is associated with higher HIV prevalence. However, research is needed to better understand how different patterns of alcohol consumption and alcohol-related problems may drive this association. In this cross-sectional study, we examined how hazardous alcohol use and alcohol-related problems such as psychological, physical, and social harms are associated with HIV status in fishing communities in Uganda. 300 (132 male, 168 female) residents of fishing communities in Uganda (75 participants from each of the following occupational groups: fishmongers, alcohol sellers, commercial sex workers (CSW), and fishermen) completed an interviewer-assisted computerized interview. We captured information on sociodemographics and HIV testing history. Prior 12-month hazardous alcohol consumption patterns and alcohol-related problems were assessed with the AUDIT and AUDADIS. 19.7%, 58.0%, and 23.3% of the sample reported being HIV positive, being HIV negative from a test within the prior 12 months, and not knowing their HIV status respectively. 18.7% reported the co-occurrence of hazardous alcohol consumption patterns and alcohol-related problems. 7.7% reported either hazardous alcohol consumption patterns or alcohol-related problems. Compared to non-drinkers, those with co-occurring hazardous consumption and alcohol-related problems had greater odds of being HIV positive (adjOR 2.75, 95% CI 1.17-6.43) and of unknown HIV status (adjOR 3.35, 95% CI 1.52-7.42). Reporting only hazardous consumption levels, only alcohol-related problems, or low-risk drinking, did not increase the odds of being HIV positive or of unknown status. Among those not HIV positive, those with co-occurring hazardous consumption and alcohol-related problems had greater odds of never having had an HIV test (adjOR 3.78, 95% CI 1.63-8.68). The co-occurrence of hazardous alcohol use and alcohol related problems appears to be a prominent risk factor for HIV infection, not knowing one's HIV status, and never testing for HIV in this setting.

The theory of masculinity in studies on HIV. A systematic review

This study aimed to describe the methodological characteristics of publications on HIV and masculinity, to identify possible information gaps and determine the main thematic areas. A systematic review was conducted of gender, masculinity, HIV infection and other sexually-transmitted infections in original articles published between 1992 and 2015. Original studies published from Pubmed and Scopus were included. A total of 303 articles were identified, of which 187 were selected. Most of the studies were qualitative and the most widely used technique was the interview. Twenty-nine-point five percent of studies were performed in South Africa, 20.8% in the USA, and 3.2% in Europe. Fifteen percent of the studies were performed in heterosexuals, 12.8% in men who have sex with men, and 60% did not specify the sexual orientation of the population. Eight thematic areas were defined, the most frequent being sexuality and risk behaviours, defined by men's need to demonstrate they were sexually active and a breadwinner. Most studies on HIV and masculinity show a gender bias by not specifying the sexual identity of the population. Studies should consider diversity in sexual and cultural identity in different contexts, including in Europe, to carry out more effective HIV interventions from a masculinity perspective.

No sex for fish: empowering women to promote health and economic opportunity in a localized place in Kenya

A pervasive cultural practice called 'jaboya' or women trading sex for fish exists at Nyamware Beach, on Lake Victoria in Kenya, where the fishing industry is the primary source of income. This case study describes how an innovative market-based solution succeeded in changing the gender dynamics on Nyamware beach and empowering women with the means of production in the industry. Over the course of 6 months, three boats were built for women to own and manage, and 29 women and 20 men received business skills training while establishing local community savings and loans associations. This project succeeded in quickly adjusting the economic imbalance that previously left women few options but to exchange sex to purchase the best fish for food and for distribution. Participating women applied resulting increased income to school fees for children and toward their households and businesses. Women owning businesses, earning income and gaining a voice in the community has changed the gender dynamics of men working on the boats for women and has positively altered the perception of women in the community. Additionally, this project offers potential health benefits such as a reduction in the transmission of HIV/AIDS and other sexually transmitted infections due to reduced rates of transactional sex, and reduced rates of depression, alcohol abuse and post-traumatic stress disorder from transactional sex, which can be traumatic. The success of this project demonstrates that small and innovative approaches addressing root causes of economic and social inequality can improve health and promote sustainable economic development.

The intersection of intimate partner violence and HIV risk among women engaging in transactional sex in Ugandan fishing villages

Intimate partner violence (IPV) may increase risk for HIV/AIDS among women engaging in transactional sex in Ugandan fishing communities. In this cross-sectional study, 115 women reporting engaging in transactional sex in Lake Victoria fishing communities completed a computerized interview. We tested associations between IPV and other HIV risk factors, with unprotected sex and HIV status, and tested moderators of the IPV-HIV risk relationship. Women reporting recent sexual IPV reported 3.36 times more unprotected sex acts (AdjExp[B] = 3.36, 95% CI = 1.29-8.69, p = 0.07). The effect of sexual IPV on sexual risk was significantly greater among alcohol and fish sellers compared to sex workers (interaction: Exp[B] = 12.29, 95% CI = 5.06-29.85, p < 0.001). Women reporting any sexual IPV were nearly four times more likely to report being HIV positive than women reporting no sexual IPV (AOR = 3.94, 95% CI = 1.22-12.66, p = 0.02). Integrated IPV and HIV interventions are needed in this context, especially among alcohol and fish sellers engaging in transactional sex.

Stigma and Discrimination faced by HIV-infected Adults on Antiretroviral Therapy for more than 1 Year in Raichur Taluk, Karnataka, India

AIM

The aim of this study was to evaluate the stress and discrimination faced by human immunodeficiency virus (HIV)-affected adult patients on antiretroviral therapy (ART) for more than 1 year.

MATERIALS AND METHODS

A cross-sectional study was carried out among 170 adults on ART, reporting to the ART center of the District Civil Hospital, for more than 1 year in Raichur Taluk, Karnataka, India. Convenience sampling technique was followed. Descriptive statistics was performed (Chi-square test) using Statistical Package for the Social Sciences version 16.0.

RESULTS

A total of 156 (91.8%) patients' families had knowledge about their seropositive status. Seventeen (10.9%) HIV-positive patients reported of change in the attitude of their family members. The main reasons for not revealing the HIV status were the internalized stigma and fear of rejection. Women faced greater discrimination from family, friends, and neighbors than men.

CONCLUSION

It is necessary to not undermine the effect of rejection due to HIV. It is the only infection that has so many associated social and psychological norms which we need to tend at the earnest. Till date, there is an existence of condescendence toward treatment approach.

CLINICAL SIGNIFICANCE

The presence of stigma and the fear of being discriminated could be a major hurdle in the rehabilitation of these patients into the mainstream society. Furthermore, it serves as an existing challenge to ascertain these individuals to achieve overall health.

Barriers and facilitators of antiretroviral therapy adherence in rural Eastern province, Zambia: the role of household economic status

In Zambia, more people living with HIV now have access to lifesaving antiretroviral therapy than ever before. However, progress in HIV treatment and care has not always resulted in lower mortality. Adherence remains a critical barrier to treatment success. The objective of this study was to examine the barriers and facilitators of antiretroviral therapy adherence, particularly the role of household economic status. The study included a cross-sectional sample of 101 people living with HIV (PLHIV) in two rural communities in eastern Zambia. Adherence was measured using patient self-assessment and pharmacy information. Household economic status included components such as occupation, income, assets, food security, and debt. Multivariable logistic regression was conducted to examine the associations between household economic factors and adherence. Our findings suggest that the role of economic status on adherence appears to be a function of the economic component. Debt and non-farming-related occupation were consistently associated with non-adherence. The association between assets and adherence depends on the type of asset. Owning more transportation-related assets was consistently associated with non-adherence, whereas owning more livestock was associated with self-reported adherence. Additionally, living in a community with fewer economic opportunities was associated with non-adherence. The associations between place of residence and pharmacy refill adherence and between transportation assets and self-reported adherence were statistically significant. Improving adherence requires a multifaceted strategy that addresses the role of economic status as a potential barrier and facilitator. Programmes that provide economic opportunities and life-skills training may help PLHIV to overcome economic, social, and psychological barriers.

Ecological correlates of multiple sexual partnerships among adolescents and young adults in urban Cape Town: a cumulative risk factor approach

Studies in South Africa have reported unsafe levels of risky sexual behvaiours among adolescents and young adults, with the country reporting the highest burden of HIV/AIDS globally, as well as a high rate of teenage pregnancy. While determinants of risky sexual behaviours have been investigated for factors occurring at the individual and household levels, not fully explored in the literature is the effect of community level factors. Furthermore, it is unclear whether risk factors occurring within the ecology of adolescents and young adults act cumulatively to influence their sexual practices. This article aims to address this knowledge gap using a case study of the Cape Area Panel Study of adolescents and young adults in urban Cape Town, South Africa. The ecological framework was adopted to guide the selection of risk factors at the individual, household, and community levels. Multivariate linear discriminant function analyses were used to select significant risk factors for multiple sexual partnerships and used to produce risk indices for the respondents. The cumulative risk approach was applied to test whether significant risk factors acted cumulatively. Findings point to the importance of ecological factors in influencing outcomes of multiple sexual partnerships among respondents and further demonstrate that ecological risk factors may act cumulatively. These findings are important for South Africa that is grappling with teenage pregnancy and disproportionate HIV epidemic among the youth.

Male Partners Involvement in Prevention of Mother-to-Child Transmission of HIV Services in Southern Central Ethiopia: In Case of Lemo District, Hadiya Zone

Male partners' involvement is a vital issue to prevent human immunodeficiency virus (HIV) transmission from mother to child; because it is much expectable that women were more vulnerable and high risk group of population portion. Therefore, to save lives of mothers and their newborn from acquiring HIV, male partners should do their maximum endeavor regardless of any determinant factors as our results revealed its status in our study context and elsewhere at past time too.

The use of cash transfers for HIV prevention--are we there yet?

Poverty and social inequality are significant drivers of the HIV epidemic and are risk factors for acquiring HIV. As such, many individuals worldwide are at risk for new HIV infection, especially young women in East and Southern Africa. By addressing these drivers, social protection programmes may mitigate the impact of poverty and social inequality on HIV risk. There is reason to believe that social protection can be used successfully for HIV prevention; social protection programmes, including cash transfers, have led to positive health outcomes and behaviour in other contexts, and they have been used successfully to promote education and increased income and employment opportunities. Furthermore, cash transfers have influenced sexual behaviour of young women and girls, thereby decreasing sexual risk factors for HIV infection. When HIV outcomes have been measured, several randomised controlled trials have shown that indirectly, cash transfers have led to reduced HIV prevalence and incidence. In these studies, school attendance and safer sexual health were directly incentivised through the cash transfer, yet there was a positive effect on HIV outcomes. In this review, we discuss the growth of social protection programmes, their benefits and impact on health, education and economic potential, and how these outcomes may affect HIV risk. We also review the studies that have shown that cash transfers can lead to reduced HIV infection, including study limitations and what questions still remain with regard to using cash transfers for HIV prevention.

What role can gender-transformative programming for men play in increasing men's HIV testing and engagement in HIV care and treatment in South Africa?

Men are less likely than women to test for HIV and engage in HIV care and treatment. We conducted in-depth interviews with men participating in One Man Can (OMC) - a rights-based gender equality and health programme intervention conducted in rural Limpopo and Eastern Cape, South Africa - to explore masculinity-related barriers to HIV testing/care/treatment and how participation in OMC impacted on these. Men who participated in OMC reported an increased capability to overcome masculinity-related barriers to testing/care/treatment. They also reported increased ability to express vulnerability and discuss HIV openly with others, which led to greater willingness to be tested for HIV and receive HIV care and treatment for those who were living with HIV. Interventions that challenge masculine norms and promote gender equality (i.e. gender-transformative interventions) represent a promising new approach to address men's barriers to testing, care and treatment.

A Decade of Combination Antiretroviral Treatment in Asia: The TREAT Asia HIV Observational Database Cohort

Asian countries have seen the expansion of combination antiretroviral therapy (cART) over the past decade. The TREAT Asia HIV Observational Database (TAHOD) was established in 2003 comprising 23 urban referral sites in 13 countries across the region. We examined trends in treatment outcomes in patients who initiated cART between 2003 and 2013. Time of cART initiation was grouped into three periods: 2003-2005, 2006-2009, and 2010-2013. We analyzed trends in undetectable viral load (VL; defined as VL <400 copies/ml), CD4 changes from pre-cART levels, and overall survival. Of 6,521 patients included, the overall median CD4 count at cART initiation was 120 cells/μl (interquartile range: 38-218). Despite an increase over time, pre-cART CD4 counts remained <200 cells/μl. Adjusted analyses showed undetectable VL was more likely when starting cART in later years [2006-2009: odds ratio (OR) = 1.76, 95% confidence interval (CI) (1.45, 2.15); and 2010-2013: OR = 3.04, 95% CI (2.33, 3.97), all p < .001, compared to 2003-2005], and survival was improved [2006-2009: subdistribution hazard ratio (SHR) = 0.41, 95% CI (0.27, 0.61), 2010-2013: SHR = 0.29, 95% CI (0.17, 0.49), all p < .001, compared to 2003-2005]. No differences in CD4 response was observed over time. Age and CD4 levels prior to cART initiation were associated with all three treatment outcomes, with older age and higher CD4 counts being associated with undetectable VL. Survival and VL response on cART have improved over the past decade in TAHOD, although CD4 count at cART initiation remained low. Greater effort should be made to facilitate earlier HIV diagnosis and linkage to care and treatment, to achieve greater improvements in treatment outcomes.

Identifying Perceived Barriers along the HIV Care Continuum: Findings from Providers, Peer Educators, and Observations of Provider-Patient Interactions in Ethiopia

Increasing the proportion of HIV-positive individuals who link promptly to and are retained in care remains challenging in sub-Saharan Africa, but little evidence is available from the provider perspective. In 4 Ethiopian health facilities, we (1) interviewed providers and peer educators about their perceptions of service delivery- and patient-level barriers and (2) observed provider-patient interactions to characterize content and interpersonal aspects of counseling. In interviews, providers and peer educators demonstrated empathy and identified nonacceptance of HIV status, anticipated stigma from unintended disclosure, and fear of antiretroviral therapy as patient barriers, and brusque counseling and insufficient counseling at provider-initiated testing sites as service delivery-related. However, observations from the same clinics showed that providers often failed to elicit patients' barriers to retention, making it unlikely these would be addressed during counseling. Training is needed to improve interpersonal aspects of counseling and ensure providers elicit and address barriers to HIV care experienced by patients.

Prevalence of HIV and Associated Risks of Sex Work among Youth in the Slums of Kampala

Purpose. The purpose of this study is to examine the prevalence of and risk factors for engaging in sex work among youth living in Kampala, Uganda. Methods. Analyses are based on a cross-sectional study (N = 1,134) of youth aged 12-18 years, living in the slums of Kampala, conducted in Spring of 2014. The analytic sample consisted of only sexually active youth (n = 590). Youth who reported engaging in sex work were compared to youth who did not report sex work. Multivariable analyses were conducted to examine factors associated with sex work. Results. Among the youth who had ever had sexual intercourse (n = 590), 13.7% (n = 81) reported engaging in sex work. Self-reported HIV prevalence was 13.9% among the total sample (n = 81) and 22.5% (n = 18) among youth engaged in sex work. Engaging in sex work was associated with being female (AOR 10.4; 95% CI: 3.9, 27.4), being an orphan (AOR 3.8; 95% CI: 1.7, 8.4), ever drinking alcohol (AOR 8.3; 95% CI 3.7, 19.0), and experiencing any rape (AOR 5.3; 95% CI: 2.9, 9.5). Discussion. The reported prevalence of sex work is high among youth in the slums of Kampala and is associated with high HIV prevalence, ever drinking alcohol, previously being raped, and being an orphan.

HIV testing, care, and treatment experiences among the steady male partners of female sex workers living with HIV in the Dominican Republic

Male steady partners of female sex workers (FSW) living with human immunodeficiency virus (HIV) represent a key population for treatment as prevention and/or pre-exposure prophylaxis interventions. This study uses data collected from male steady partners who were referred by FSW living with HIV participating in a multi-level HIV prevention and care intervention in Santo Domingo, Dominican Republic. We conducted a socio-behavioral survey and HIV testing with all men (n = 64) and 16 in-depth interviews with a sub-sample to obtain more depth. Thirty-five of the 64 participants were living with HIV; 27 were previously diagnosed and 8 were diagnosed during our study. As a result, 45% of men were members of sero-discordant sexual partnerships. Of men with no previous HIV diagnosis (n = 37), 15 had never been tested for HIV and nine had not been tested in the past two years. Ninety-three percent of men previously diagnosed with HIV reported receiving HIV care in the past 6 months and 78% were taking anti-retrovirals. Low HIV testing was partly due to men not feeling at risk for HIV, despite having an HIV-infected partner. Additionally, a lack of tailored care inhibited engagement in anti-retroviral treatment for those infected. HIV testing was low, highlighting a need for test-and-treat strategies. Men not living with HIV would benefit from regular testing and would be good candidates for pre-exposure prophylaxis. While almost all men who had been diagnosed with HIV were engaged in care and adherent to anti-retroviral therapy, future research should assess whether they are achieving optimal HIV outcomes for their health and prevention of ongoing transmission.

Risk Factors for HIV Transmission and Barriers to HIV Disclosure: Metropolitan Atlanta Youth Perspectives

Youth carry the highest incidence of HIV infection in the United States. Understanding adolescent and young adult (AYA) perspectives on HIV transmission risk is important for targeted HIV prevention. We conducted a mixed methods study with HIV-infected and uninfected youth, ages 18-24 years, from Atlanta, GA. We provided self-administered surveys to HIV-infected and HIV-uninfected AYAs to identify risk factors for HIV acquisition. By means of computer-assisted thematic analyses, we examined transcribed focus group responses on HIV education, contributors to HIV transmission, and pre-sex HIV status disclosure. The 68 participants had the following characteristics: mean age 21.5 years (standard deviation: 1.8 years), 85% male, 90% black, 68% HIV-infected. HIV risk behaviors included the perception of condomless sex (Likert scale mean: 8.0) and transactional sex (88% of participants); no differences were noted by HIV status. Qualitative analyses revealed two main themes: (1) HIV risk factors among AYAs, and (2) barriers to discussing HIV status before sex. Participants felt the use of social media, need for immediate gratification, and lack of concern about HIV disease were risk factors for AYAs. Discussing HIV status with sex partners was uncommon. Key reasons included: fear of rejection, lack of confidentiality, discussion was unnecessary in temporary relationships, and disclosure negatively affecting the mood. HIV prevention strategies for AYAs should include improving condom use frequency and HIV disclosure skills, responsible utilization of social media, and education addressing HIV prevention including the risks of transactional sex.

Exposure to violence and psychological well-being over time in children affected by HIV/AIDS in South Africa and Malawi

Many of the risk factors for violence against children are particularly prevalent in families and communities affected by HIV/AIDS. Yet, in sub-Saharan Africa, where HIV rates are high, efforts to prevent or address violence against children and its long-lasting effects are hampered by a lack of evidence. We assessed the relationship between violence exposure and mental health among HIV-affected children attending community-based organisations in South Africa (n = 834) and Malawi (n = 155, total sample n = 989) at baseline and 12-15-month follow-up. Exposure to violence in the home and in the community was high. HIV-negative children who lived with an HIV-positive person experienced most violence overall, followed by HIV-positive children. Children unaffected by HIV experienced least violence (all p < .05). Interpersonal violence in the home predicted child depression (β = 0.17, p < .001), trauma symptoms (β = 0.17, p < .001), lower self-esteem (β = -0.17, p < .001), and internalising and externalising behavioural problems (β = 0.07, p < .05), while exposure to community violence predicted trauma symptoms (β = 0.16, p < .001) and behavioural problems (β = 0.07, p < .05). Harsh physical discipline predicted lower self-esteem (β = -0.18, p < .001) and behavioural problems for children (β = 0.24, p < .001). Exposure to home (OR: 1.89, 95% CI: 1.23-2.85) and community violence predicted risk behaviour (OR: 2.39, 95% CI: 1.57-3.62). Over time, there was a decrease in depressed mood and problem behaviours, and an increase in self-esteem for children experiencing different types of violence at baseline. This may have been due to ongoing participation in the community-based programme. These data highlight the burden of violence in these communities and possibilities for programmes to include violence prevention to improve psychosocial well-being in HIV-affected children.

Mortality Risk After AIDS-Defining Opportunistic Illness Among HIV-Infected Persons--San Francisco, 1981-2012

OBJECTIVE

To examine whether improved human immunodeficiency virus (HIV) treatment was associated with better survival after diagnosis of AIDS-defining opportunistic illnesses (AIDS-OIs) and how survival differed by AIDS-OI.

DESIGN

We used HIV surveillance data to conduct a survival analysis.

METHODS

We estimated survival probabilities after first AIDS-OI diagnosis among adult patients with AIDS in San Francisco during 3 treatment eras: 1981-1986; 1987-1996; and 1997-2012. We used Cox proportional hazards models to determine adjusted mortality risk by AIDS-OI in the years 1997-2012.

RESULTS

Among 20 858 patients with AIDS, the most frequently diagnosed AIDS-OIs were Pneumocystis pneumonia (39.1%) and Kaposi sarcoma (20.1%). Overall 5-year survival probability increased from 7% in 1981-1986 to 65% in 1997-2012. In 1997-2012, after adjustment for known confounders and using Pneumocystis pneumonia as the referent category, mortality rates after first AIDS-OI were highest for brain lymphoma (hazard ratio [HR], 5.14; 95% confidence interval [CI], 2.98-8.87) and progressive multifocal leukoencephalopathy (HR, 4.22; 95% CI, 2.49-7.17).

CONCLUSIONS

Survival after first AIDS-OI diagnosis has improved markedly since 1981. Some AIDS-OIs remain associated with substantially higher mortality risk than others, even after adjustment for known confounders. Better prevention and treatment strategies are still needed for AIDS-OIs occurring in the current HIV treatment era.

Improved survival with co-trimoxazole prophylaxis among people living with HIV/AIDS who initiated antiretroviral treatment in Henan Province, China

OBJECTIVES

This study aims to evaluate the effect of co-trimoxazole (CTX) prophylaxis on mortality reduction among HIV-infected patients receiving antiretroviral therapy (ART) in Henan Province, China.

DESIGN

We conducted a retrospective study.

METHODS

All individuals aged 15 years and older who initiated ART between 2008 and 2010 in Henan Province with completed CTX prophylaxis treatment information were included. The effect of CTX prophylaxis was estimated using Kaplan-Meier survival analysis and multivariate Cox proportional hazard modeling for mortality at 3-months and 12-months after ART initiation.

RESULTS

Overall mortality among patients receiving both ART and CTX was nearly double at 3-months after ART initiation compared with that at 12-months (12.4 per 100 PY vs 6.3 per 100 PY, p < 0.01). After adjusting for gender, age, TB history, year of ART initiation and CD4 count at ART initiation, CTX was associated with a significant reduction in 12-month mortality (adjusted hazard ratio (AHR) = 0.65, 95% confidence interval (CI): 0.44-0.95; p = 0.027) compared with persons not receiving CTX. The protective effect was more pronounced in the first 3 months after ART initiation (AHR = 0.53, 95% CI: 0.32-0.89; p = 0.017).

CONCLUSION

CTX prophylaxis together with ART reduced mortality of adult HIV patients during the first 12 months of ART in Henan Province, China. The effect was highest in the first 3 months of ART. CTX should be prescribed to all HIV-infected adults who initiate ART.

'Dented' and 'resuscitated' masculinities: the impact of HIV diagnosis and/or enrolment on antiretroviral treatment on masculine identities in rural eastern Uganda

There is limited research on the impact of HIV or its treatment on men's identity construction and gender roles in sub-Saharan Africa. Based on in-depth research with 26 men in rural Uganda, this article discusses men's vulnerabilities and shifting gender relations and sense of masculinity resulting from HIV infection or enrolment on treatment in eastern Uganda. The findings suggest two broad categories of masculinity: respectable and reputational. HIV infection and illness dented masculinity as men lost authority within the domestic sphere. A weakened provider role and over-reliance on wives and children undermined masculinity as family head, and social sanctioning of their sexual activity, undermined conventional masculine identities predicted on reputation. However, treatment led to a more reflexive approach to demonstrating masculinity, increased attentiveness to health and restored hope to father children free of HIV, resuscitating respectable masculinities. The balance between eroded and restored masculinity varied between men by their treatment history, age, family composition and state of health. HIV support agencies need to pay attention to the way HIV and antiretroviral treatment (ART) influence men's perception of their masculinity and support them to overcome the anxieties about dented or eroded masculinity, while building on the positive ways in which treatment restores masculinity to support men's adherence to HIV treatment. In particular, there is a need to support men's engagement in productive activities that bring income so that men can regain their provider roles following ART and restore their respectability in both the public and the domestic sphere.

Assessment of the impact of cotrimoxazole prophylaxis on key outcomes among HIV-infected adults in low- and middle-income countries: a systematic review

BACKGROUND

Cotrimoxazole (CTX) prophylaxis is among the key interventions provided to HIV-infected individuals in resource-limited settings. We conducted a systematic review of the available evidence.

METHODS

MEDLINE, Embase, Global Health, CINAHL, SOCA, and African Index Medicus (AIM) were used to identify articles relevant to the CTX prophylaxis intervention from 1995 to 2014. Included articles addressed impact of CTX prophylaxis on the outcomes of mortality, morbidity, retention in care, quality of life, and/or prevention of ongoing HIV transmission. We rated the quality of evidence in individual articles and assessed the overall quality of the body of evidence, the expected impact, and the cost effectiveness (CE) for each outcome.

RESULTS

Of the initial 1418 identified articles, 42 met all inclusion criteria. These included 9 randomized controlled trials, 26 observational studies, 2 systematic reviews with meta-analysis, 1 other systematic review, and 4 CE studies. The overall quality of evidence was rated as "good" and the expected impact "high" for both mortality and morbidity. The overall quality of evidence from the 4 studies addressing retention in care was rated as "poor," and the expected impact on retention was rated as "uncertain." The 4 assessed CE studies showed that provision of CTX prophylaxis is cost effective and sometimes cost saving. No studies addressed impact on quality of life or HIV transmission.

CONCLUSIONS

CTX prophylaxis is a cost-effective intervention with expected high impact on morbidity and mortality reduction in HIV-infected adults in resource-limited settings. Benefits are seen in both pre-antiretroviral therapy and antiretroviral therapy populations.

Co-trimoxazole prophylaxis in adults, including pregnant women, with HIV: a systematic review and meta-analysis

INTRODUCTION

Co-trimoxazole prophylaxis is used to reduce morbidity and mortality in people with HIV. We systematically reviewed three topics related to co-trimoxazole prophylaxis to update WHO guidelines: initiation, discontinuation, and dose.

METHODS

We searched PubMed, Embase, WHO Global Index Medicus, and clinical trial registries in November, 2013, for randomised controlled trials and observational studies including co-trimoxazole prophylaxis and a comparator group. Studies were eligible if they reported death, WHO clinical stage 3 or 4 events, admittance to hospital, severe bacterial infections, tuberculosis, pneumonia, diarrhoea, malaria, or treatment-limiting adverse events. Infant mortality, low birthweight, and placental malaria were additional outcomes for the comparison of co-trimoxazole prophylaxis and intermittent preventive treatment for malaria in pregnant women (IPTp). We compared a dose of 480 mg co-trimoxazole once a day with one of 960 mg co-trimoxazole once a day. We used a 10% margin for non-inferiority and equivalence analyses. We used random-effects models for all meta-analyses. This study is registered with PROSPERO, number CRD42014007163.

FINDINGS

19 articles, published from 1995 to 2014 and including 35 328 participants, met the inclusion criteria. Co-trimoxazole prophylaxis reduced rates of death (hazard ratio [HR] 0·40, 95% CI 0·26-0·64) when started at CD4 counts of 350 cells per μL or lower with antiretroviral therapy (ART) worldwide. Co-trimoxazole prophylaxis started at higher than 350 cells per μL without ART reduced rates of death (0·50, 0·30-0·83) and malaria (0·25, 0·10-0·57) in Africa. Co-trimoxazole prophylaxis was non-inferior to IPTp with respect to infant mortality (risk difference [RD] -0·05, 95% CI -0·12 to 0·02), low birthweight (0·00, -0·07 to 0·07), and placental malaria (0·00, -0·10 to 0·10). Co-trimoxazole prophylaxis continuation after ART-induced recovery with CD4 counts higher than 350 cells per μL reduced admittances to hospital (HR 0·42, 95% CI 0·22-0·80), pneumonia (0·73, 0·61-0·88), malaria (0·03, 0·01-0·10), and diarrhoea (0·61, 0·48-0·78) in Africa. A dose of 480 mg co-trimoxazole prophylaxis once a day did not reduce treatment-limiting adverse events compared with 960 mg once a day (RD -0·07, 95% CI -0·52 to 0·39).

INTERPRETATION

Co-trimoxazole prophylaxis should be given with ART in people with CD4 counts of 350 cells per μL or lower in low-income and middle-income countries. Co-trimoxazole prophylaxis should be provided irrespective of CD4 count in settings with a high burden of infectious diseases. Pregnant women with HIV in Africa should use co-trimoxazole rather than IPTp to prevent malaria complications in infants. Further research is needed to inform dose optimisation and co-trimoxazole use in the context of expanded ART in different epidemiological settings.

FUNDING

None.

The expanding role of co-trimoxazole in developing countries

Co-trimoxazole is an inexpensive, broad-spectrum antimicrobial drug that is widely used in developing countries. Before antiretroviral therapy (ART) scale-up, co-trimoxazole prophylaxis reduced morbidity and mortality in adults and children with HIV by preventing bacterial infections, diarrhoea, malaria, and Pneumocystis jirovecii pneumonia, despite high levels of microbial resistance. Co-trimoxazole prophylaxis reduces early mortality by 58% (95% CI 39-71) in adults starting ART. Co-trimoxazole provides ongoing protection against malaria and non-malaria infections after immune reconstitution in ART-treated individuals in sub-Saharan Africa, leading to a change in WHO guidelines, which now recommend long-term co-trimoxazole prophylaxis for adults and children in settings with a high prevalence of malaria or severe bacterial infections. Co-trimoxazole prophylaxis is recommended for HIV-exposed infants from age 4-6 weeks; however, the risks and benefits of co-trimoxazole during infancy are unclear. Co-trimoxazole prophylaxis reduces anaemia and improves growth in children with HIV, possibly by reducing inflammation, either through direct immunomodulatory activity or through effects on the intestinal microbiota leading to reduced microbial translocation. Ongoing trials are now assessing the ability of adjunctive co-trimoxazole to reduce mortality in children after severe anaemia or severe acute malnutrition. In this Review, we discuss the mechanisms of action, benefits and risks, and clinical trials of co-trimoxazole in developing countries.

Relationship between school dropout and teen pregnancy among rural South African young women

BACKGROUND

Sexual activity may be less likely to occur during periods of school enrolment because of the structured and supervised environment provided, the education obtained and the safer peer networks encountered while enrolled. We examined whether school enrolment was associated with teen pregnancy in South Africa.

METHODS

Using longitudinal demographic surveillance data from the rural Agincourt sub-district, we reconstructed the school enrolment status from 2000 through 2011 for 15 457 young women aged 12-18 years and linked them to the estimated conception date for each pregnancy during this time. We examined the effect of time-varying school enrolment on teen pregnancy using a Cox proportional hazard model, adjusting for: age; calendar year; household socioeconomic status; household size; and gender, educational attainment and employment of household head. A secondary analysis compared the incidence of pregnancy among school enrolees by calendar time: school term vs school holiday.

RESULTS

School enrolment was associated with lower teen pregnancy rates [adjusted hazard ratio (95% confidence interval): 0.57 (0.50, 0.65)].This association was robust to potential misclassification of school enrolment. For those enrolled in school, pregnancy occurred less commonly during school term than during school holidays [incidence rate ratio (95% confidence interval): 0.90 (0.78, 1.04)].

CONCLUSIONS

Young women who drop out of school may be at higher risk for teen pregnancy and could likely benefit from receipt of accessible and high quality sexual health services. Preventive interventions designed to keep young women in school or addressing the underlying causes of dropout may also help reduce the incidence of teen pregnancy.

Cotrimoxazole prophylaxis and antiretroviral therapy: an observational cohort study in China

Objective

To assess if cotrimoxazole prophylaxis administered early during antiretroviral therapy (ART) reduces mortality in Chinese adults who are infected with human immunodeficiency virus (HIV).

Methods

We did a retrospective observational cohort study using data from the Chinese national free antiretroviral database. Patients older than 14 years who started ART between 1 January 2010 and 31 December 2012 and had baseline CD4+ T-lymphocyte (CD4+ cell) count less than 200 cells/µL were followed until death, loss to follow-up or 31 December 2013. Hazard ratios (HRs) for several variables were calculated using multivariate analyses.

Findings

The analysis involved 23 816 HIV-infected patients, 2706 of whom died during the follow-up. Mortality in patients who did and did not start cotrimoxazole during the first 6 months of ART was 5.3 and 7.0 per 100 person–years, respectively. Cotrimoxazole was associated with a 37% reduction in mortality (hazard ratio, HR: 0.63; 95% confidence interval, CI: 0.56–0.70). Cotrimoxazole in addition to ART reduced mortality significantly over follow-up lasting 6 months (HR: 0.65; 95% CI: 0.59–0.73), 12 months (HR: 0.58; 95% CI: 0.49–0.70), 18 months (HR: 0.49; 95% CI: 0.38–0.63) and 24 months (HR: 0.66; 95% CI: 0.48–0.90). The mortality reduction was evident in patients with baseline CD4+ cell counts less than 50 cells/µL (HR: 0.60; 95% CI: 0.54–0.67), 50–99 cells/µL (HR: 0.66; 95% CI: 0.56–0.78) and 100–199 cells/µL (HR: 0.78; 95% CI: 0.62–0.98).

Conclusion

Cotrimoxazole prophylaxis started early during ART reduced mortality and should be offered to HIV-infected patients in low- and middle-income countries.

Efficacy of a savings-led microfinance intervention to reduce sexual risk for HIV among women engaged in sex work: a randomized clinical trial

OBJECTIVES

We tested whether a structural intervention combining savings-led microfinance and HIV prevention components would achieve enhanced reductions in sexual risk among women engaging in street-based sex work in Ulaanbaatar, Mongolia, compared with an HIV prevention intervention alone.

METHODS

Between November 2011 and August 2012, we randomized 107 eligible women who completed baseline assessments to either a 4-session HIV sexual risk reduction intervention (HIVSRR) alone (n=50) or a 34-session HIVSRR plus a savings-led microfinance intervention (n=57). At 3- and 6-month follow-up assessments, participants reported unprotected acts of vaginal intercourse with paying partners and number of paying partners with whom they engaged in sexual intercourse in the previous 90 days. Using Poisson and zero-inflated Poisson model regressions, we examined the effects of assignment to treatment versus control condition on outcomes.

RESULTS

At 6-month follow-up, the HIVSRR plus microfinance participants reported significantly fewer paying sexual partners and were more likely to report zero unprotected vaginal sex acts with paying sexual partners.

CONCLUSIONS

Findings advance the HIV prevention repertoire for women, demonstrating that risk reduction may be achieved through a structural intervention that relies on asset building, including savings, and alternatives to income from sex work.

Global HIV epidemiology: A guide for strategies in prevention and care

Global trends in HIV incidence are estimated typically by serial prevalence surveys in selected sentinel populations or less often in representative population samples. Incidence estimates are often modeled because cohorts are costly to maintain and are rarely representative of larger populations. From global trends, we can see reason for cautious optimism. Downward trends in generalized epidemics in Africa, concentrated epidemics in persons who inject drugs (PWID), some female sex worker cohorts, and among older men who have sex with men (MSM) have been noted. However, younger MSM and those from minority populations, as with black MSM in the United States, show continued transmission at high rates. Among the many HIV prevention strategies, current efforts to expand testing, linkage to effective care, and adherence to antiretroviral therapy are known as "treatment as prevention" (TasP). A concept first forged for the prevention of mother to child transmission, TasP generates high hopes that persons treated early will derive considerable clinical benefits and that lower infectiousness will reduce transmission in communities. With the global successes of risk reduction for PWID, we have learned that reducing marginalization of the at-risk population, implementation of nonjudgmental and pragmatic sterile needle and syringe exchange programs, and offering of opiate substitution therapy to help persons eschew needle use altogether can work to reduce the HIV epidemic. Never has the urgency of stigma reduction and guarantees of human rights been more urgent; a public health approach to at-risk populations requires that to avail themselves of prevention services and they must feel welcomed.

Gender norms, poverty and armed conflict in Côte D'Ivoire: engaging men in women's social and economic empowerment programming

Engaging men is a critical component in efforts to reduce intimate partner violence (IPV). Little is known regarding men's perspectives of approaches that challenge inequitable gender norms, particularly in settings impacted by armed conflict. This article describes men's experiences with a women's empowerment program and highlights men's perceptions of gender norms, poverty and armed conflict, as they relate to achieving programmatic goals. Data are from 32 Ivorian men who participated in indepth interviews in 2012. Interviews were undertaken as part of an intervention that combined gender dialogue groups for both women and their male partners with women's only village savings and loans programs to reduce IPV against women. Findings suggested that in the context of armed conflict, traditional gender norms and economic stressors experienced by men challenged fulfillment of gender roles and threatened men's sense of masculinity. Men who participated in gender dialogue groups discussed their acceptance of programming and identified improvements in their relationships with their female partners. These men further discussed increased financial planning along with their partners, and attributed such increases to the intervention. Addressing men's perceptions of masculinity, poverty and armed conflict may be key components to reduce men's violence against women in conflict-affected settings.

Partner testing, linkage to care, and HIV-free survival in a program to prevent parent-to-child transmission of HIV in the Highlands of Papua New Guinea

Background

To eliminate new pediatric HIV infections, interventions that facilitate adherence, including those that minimize stigma, enhance social support, and mitigate the influence of poverty, will likely be required in addition to combination antiretroviral therapy (ART). We examined the relationship between partner testing and infant outcome in a prevention of parent-to-child transmission of HIV program, which included a family-centered case management approach and a supportive environment for partner disclosure and testing.

Design

We analyzed routinely collected data for women and infants who enrolled in the parent-to-child transmission of HIV program at Goroka Family Clinic, Eastern Highlands Provincial Hospital, Papua New Guinea, from 2007 through 2011.

Results

Two hundred and sixty five women were included for analysis. Of these, 226 (85%) had a partner, 127 (56%) of whom had a documented HIV test. Of the 102 HIV-infected partners, 81 (79%) had been linked to care. In adjusted analyses, we found a significantly higher risk of infant death, infant HIV infection, or loss to follow-up among mother–infant pairs in which the mother reported having no partner or a partner who was not tested or had an unknown testing status. In a second multivariable analysis, infants born to women with more time on ART or who enrolled in the program in later years experienced greater HIV-free survival.

Conclusions

In a program with a patient-oriented and family-centered approach to prevent vertical HIV transmission, the majority of women's partners had a documented HIV test and, if positive, linkage to care. Having a tested partner was associated with program retention and HIV-free survival for infants. Programs aiming to facilitate diagnosis disclosure, partner testing, and linkage to care may contribute importantly to the elimination of pediatric HIV.
