Lack of pre-antiretroviral care and competition from traditional healers, crucial risk factors for very late initiation of antiretroviral therapy for HIV--a case-control study from eastern Uganda

Hearing From Men Living With HIV: Experiences With HIV Testing, Treatment, and Viral Load Suppression in Four High-Prevalence Countries in Sub-Saharan Africa

Engaging men in HIV services remains a challenge across sub-Saharan Africa. There is a critical need to better understand facilitators of men's successful engagement with HIV services and assess if there are similarities across contexts. We conducted in-depth interviews and focus group discussions with 92 men living with HIV (MLHIV) across Malawi, Uganda, South Africa, and Eswatini, most of whom had been diagnosed with HIV within the last 5 years. We coded interviews for themes using a constant-comparative approach. We contextualized our findings within a socioecological framework. HIV testing was primarily motivated by illness (individual level), though illness was sometimes accompanied by prompting and support from healthcare providers and/or intimate partners. Once diagnosed, nearly all participants reported immediate linkage to care, initiation of antiretroviral therapy (ART), and subsequent ART adherence. ART initiation and adherence were facilitated by men's sense of agency and ownership over their health (individual level), social support from intimate partners, friends, and family (interpersonal/network level), supportive-directive counseling from healthcare providers (institutional/health systems level), and male-friendly services, i.e., rapid, respectful, private (institutional/health systems level). Health literacy regarding viral suppression (individual level), strengthened by patient-provider communication (institutional/health systems level), was highest in Uganda, where most men could discuss viral load testing experiences, report their viral load status (most reported suppressed), and demonstrate an understanding of treatment as prevention. Elsewhere, few participants understood what viral load suppression was and even fewer knew their viral load status. Our findings reveal socioecological-level facilitators of men's progress across the HIV-care continuum. Programs may want to leverage facilitators of ART initiation and adherence that span socioecological levels—e.g., healthcare ownership and agency, social support, supportive-directive counseling—and apply them to each end of the continuum to encourage early HIV testing/diagnosis and improve health literacy to help men understand and achieve viral load suppression.

Prevalence and factors associated with delayed antiretroviral therapy initiation among adults with HIV in Alebtong district, Northern Uganda: A facility-based study

Globally, an estimated 36.7 million people were living with HIV (PLWH) and of these, 2.1 million were newly infected and 1.1 million died of AIDS in 2015. By 2016, only 67% of adults eligible for ART were enrolled in ART in Uganda. Delayed ART initiation has been shown to contribute to the continued transmission of HIV as well as to higher morbidity and mortality among persons living with HIV. Our study examined the prevalence and factors associated with delayed ART initiation among adults with HIV in Alebtong district, Northern Uganda. A cross-sectional study involving 432 adults living with HIV was conducted between March and June 2018 in Alebtong district. Quantitative data were collected using interviewer-administered questionnaires and desk reviews using a data extraction tool. A binary logistic regression using a hierarchical modelling technique was used at the multivariable level to determine associations at a 95% confidence interval and p<0.05 using SPSS Statistics software version 23.0. Overall, 432 participants were enrolled in the study, of whom 18.1% (78/432) had delayed ART initiation. After final adjustment, our key findings showed a significantly lower odds of delayed ART initiation among older respondents (aOR = 0.35, 95% CI: 0.16-0.76); adherence to HIV clinic appointments, (aOR = 0.06, 95% CI: 0.02-0.15); and linkage to the HIV clinic the same day HIV test was conducted (aOR = 0.21, 95% CI: 0.08-0.55). However, a significantly higher odds of delayed ART initiation was observed among those whose cultures do not support the use of ART (aOR = 10.62, 95% CI: 3.04-32.08). Reducing delayed ART initiation in the district requires strengthening the involvement of adolescents and young people in the HIVAIDS programming, scaling up the implementation of the same-day ART initiation policy, and addressing negative cultural beliefs affecting early ART initiation in the district.

What Shapes Late HIV Diagnosis in Vietnam? A Qualitative Investigation of Multilevel Factors

Late HIV treatment remains a global public health issue despite significant efforts. To better understand what shapes this issue, we interviewed 36 Vietnamese ART-naive patients who came to HIV treatment in 2017. Half of them had intake CD4 counts fewer than 100 cells/mm³, the others had intake CD4 counts of 350 cells/mm³ and above. Late diagnosis was the reason of late treatment in our sample. Most late presenters were not members of the key populations at increased risk of HIV (e.g., people who inject drugs, commercial sex workers, and men who have sex with men). Individual-level factors included low risk appraisal, habit of self-medication, and fear of stigma. Network and structural-level factors included challenges to access quality health care, normalization of HIV testing in key populations and inconsistent provider-initiated HIV testing practices. Structural interventions coupled with existing key population-targeted strategies would improve the issue of late HIV diagnosis.

Understanding men's networks and perceptions of leadership to promote HIV testing and treatment in Agincourt, South Africa

Understanding informal leadership in high HIV prevalence settings is important for the success of popular opinion leader (POL) and other HIV testing and treatment promotion strategies which aim to leverage the influence of these leaders. We conducted a study in Mpumalanga province, South Africa, in which we aimed to: (1) describe men's personal networks and key social relationships; and (2) describe the types of individuals men identify as leaders. We administered a structured questionnaire with 45 men (15 HIV-positive and 30 HIV-negative) in which men enumerated and described characteristics of individuals they share personal matters with, and people they considered as leaders. We further conducted in-depth interviews with 25 of these men to better understand men's conceptualisation of leadership in their community. Family members were prominent in men's personal networks and among the leaders they nominated. Men living with HIV were much more likely to know others living with HIV, and described friendships on the basis of the shared experience of HIV treatment. Future POL interventions aiming to promote HIV testing and care among men in rural South Africa should consider the importance of family in community leadership, and seek to leverage the influence of connections between men living with HIV.

Perceived behavioural predictors of late initiation to HIV/AIDS care in Gurage zone public health facilities: a cohort study using health belief model

Objective

The study was aimed to measure incidence density rate and identify perceived behavioural believes of late initiation to HIV/AIDS care in Gurage zone public health facilities from September 2015 to November 2016.

Results

The incidence density rates of late initiation to HIV/AIDS care were 2.21 per 100 person-months of observation. HIV positive individuals who did not perceived susceptibility were 8.46 times more likely delay to start HIV/AIDS care than their counter parts [OR = 8.46 (95% CI 3.92, 18.26)]. HIV infected individuals who did not perceived severity of delayed ART initiation were 6.13 time more likely to delay than HIV infected individuals who perceived its severity [OR = 6.13 (95% CI 2.95, 12.73)]. HIV positive individuals who didn’t have self-efficacy were 2.35 times more likely delay to start HIV/AIDS care than HIV positive individuals who have self-efficacy [OR = 2.35 (95% CI 1.09, 5.05)].

Conclusions

The study revealed that high incidence density rates of delayed initiation for HIV care and variations were explained by poor wealth, and perceived threat and benefit. Therefore, interventions should be designed to initiate care at their diagnosis time.

Brief counselling after home-based HIV counselling and testing strongly increases linkage to care: a cluster-randomized trial in Uganda

Introduction

The aim of this study was to determine whether counselling provided subsequent to HIV testing and referral for care increases linkage to care among HIV‐positive persons identified through home‐based HIV counselling and testing (HBHCT) in Masaka, Uganda.

Methods

The study was an open‐label cluster‐randomized trial. 28 rural communities were randomly allocated (1:1) to intervention (HBHCT, referral and counselling at one and two months) or control (HBHCT and referral only). HIV‐positive care‐naïve adults (≥18 years) were enrolled. To conceal participants’ HIV status, one HIV‐negative person was recruited for every three HIV‐positive participants. Primary outcomes were linkage to care (clinic‐verified registration for care) status at six months, and time to linkage. Primary analyses were intention‐to‐treat using random effects logistic regression or Cox regression with shared frailty, as appropriate.

Results

Three hundred and two(intervention, n = 149; control, n = 153) HIV‐positive participants were enrolled. Except for travel time to the nearest HIV clinic, baseline participant characteristics were generally balanced between trial arms. Retention was similar across trial arms (92% overall). One hundred and twenty‐seven (42.1%) participants linked to care: 76 (51.0%) in the intervention arm versus 51 (33.3%) in the control arm [odds ratio = 2.18, 95% confidence interval (CI) = 1.26–3.78; p = 0.008)]. There was evidence of interaction between trial arm and follow‐up time (p = 0.009). The probability of linkage to care, did not differ between arms in the first two months of follow‐up, but was subsequently higher in the intervention arm versus the control arm [hazard ratio = 4.87, 95% CI = 1.79–13.27, p = 0.002].

Conclusions

Counselling substantially increases linkage to care among HIV‐positive adults identified through HBHCT and may enhance efforts to increase antiretroviral therapy coverage in sub‐Saharan Africa.

Treatment interruption in HIV-positive patients followed up in Cameroon's antiretroviral treatment programme: individual and health care supply-related factors (ANRS-12288 EVOLCam survey)

INTRODUCTION

Decreasing international financial resources for HIV and increasing numbers of antiretroviral treatment (ART)-treated patients may jeopardise treatment continuity in low-income settings. Using data from the EVOLCam ANRS-12288 survey, this study aimed to document the prevalence of unplanned treatment interruption for more than 2 consecutive days (TI>2d) and investigate the associated individual and health care supply-related factors within the Cameroonian ART programme.

METHODS

A cross-sectional mixed methods survey was carried out between April and December 2014 in 19 HIV services of the Centre and Littoral regions. A multilevel logistic model was estimated on 1885 ART-treated patients in these services to investigate factors of TI>2d in the past 4 weeks.

RESULTS

Among the study population, 403 (21%) patients reported TI>2d. Patients followed up in hospitals reporting ART stock-outs were more likely to report TI>2d while those followed up in the Littoral region, in medium- or small-sized hospitals and in HIV services proposing financial support were at lower risk of TI>2d. The following individual factors were also associated with a lower risk of TI>2d: living in a couple, having children, satisfaction with attention provided by doctor, tuberculosis co-infection and not having consulted a traditional healer.

CONCLUSIONS

Besides identifying individual factors of TI>2d, our study highlighted the role of health care supply-related factors in shaping TI in Cameroon's ART programme, especially the deleterious effect of ART stock-outs. Our results also suggest that the high proportion of patients reporting TI could jeopardise progress in the fight against HIV in the country, unless effective measures are quickly implemented like ensuring the continuity of ART supply.

An open-label cluster randomised trial to evaluate the effectiveness of a counselling intervention on linkage to care among HIV-infected patients in Uganda: Study design

Introduction

Home-based HIV counselling & testing (HBHCT) is highly acceptable and has the potential to increase HIV testing uptake in sub-Saharan Africa. However, data are lacking on strategies that can effectively link HIV-positive individuals identified through HBHCT to care. This trial was designed to assess the effectiveness of two brief home-based counselling sessions on linkage to care, provided subsequent to referral for care among HIV-positive patients identified through HBHCT in a rural community in Masaka district, Uganda.

Methods

28 communities (clusters) were randomly allocated to control (referral only) and intervention (referral and follow-up counselling) arms (n = 14 clusters/arm). Randomisation was stratified on distance from the district capital (≤10 km vs > 10 km) and cluster size (larger single village vs combined small villages), and restricted to ensure balance on selected cluster characteristics. A list of possible allocations was generated and one randomly selected at a public ceremony. HBHCT is being offered to all adults (≥18 years), and HIV-positive individuals not yet in care are eligible for enrolment. The intervention is provided at one and two months post-enrolment. Primary outcomes, assessed 6 months after enrolment, are: the proportion of individuals linking to HIV care within 6 months of HIV diagnosis and time to linkage. The primary analysis will be based on individual-level data.

Discussion

This study will provide evidence on the impact of a counselling intervention on linkage to care among adults identified with HIV infection through HBHCT. Interpretation of the trial outcomes will be aided by results from an on-going qualitative sub-study.

Late presentation for diagnosis of HIV infection among HIV positive patients in South Tigray Zone, Ethiopia

BACKGROUND

In spite of the availability and accessibility of HIV testing opportunities and efforts, people are being late to test in the course of HIV infection. Late diagnosis leads to late anti-retroviral therapy initiation which in turn results in poor treatment outcome and prognosis of the disease. The aim of this study was to determine the prevalence and predictors of late HIV diagnosis among HIV-infected patients in South Tigray Zone, Ethiopia.

METHODS

A facility based cross sectional study was conducted among HIV positive patients from February 1-30, 2014 in Southern Tigray, Ethiopia. Multistage sampling technique was employed to select the study participants. Data were collected by reviewing patient medical card and interviewing using structured questionnaire. Data were entered using Epi-Data version 3.1 and analyzed using SPSS version 20.0. Both bivariate and multivariate logistic regressions were modeled to evaluate the association of predictors with late diagnosis of HIV infection.

RESULTS

Out of 789 study participants, 68.8 % of them were late for HIV diagnosis. Feeling healthy (65.7 %), fear of stigma and discrimination (32.4 %) and using traditional treatment (1.5 %) were reported as the main reasons for late HIV diagnosis. Use of Khat [AOR = 3.27, 95 % CI (1.75, 6.13)], bed ridden functional status [AOR = 2.66, 95 % CI (1.60, 4.42)], ambulatory functional status [AOR = 1.56, 95 % CI (1.03, 2.35)] and Muslim religion [AOR = 2.26, 95 % CI (1.13, 4.49)] were significantly associated with late presentation for HIV diagnosis.

CONCLUSIONS

High prevalence of late HIV diagnosis was recorded in Southern Tigray Zone, Ethiopia. Public health educations and campaigns targeted at improving early diagnosis and prognosis of people living with HIV/AIDS in Southern Tigray, Northern Ethiopia should be underway.

Medical pluralism predicts non-ART use among parents in need of ART: a community survey in KwaZulu-Natal, South Africa

Despite documented common use of traditional healers and efforts to scale up antiretroviral treatment (ART) in sub-Saharan Africa, evidence on whether medical pluralism predicts ART use is inconclusive and restricted to clinic settings. This study quantitatively assesses whether medical pluralism predicts ART use among parents in need of ART in South Africa. 2,477 parents or primary caregivers of children were interviewed in HIV-endemic communities of KwaZulu-Natal. Analysis used multiple logistic regression on a subsample of 435 respondents in need of ART, who reported either medical pluralism (24.6 %) or exclusive public healthcare use (75.4 %). Of 435 parents needing ART, 60.7 % reported ART use. Medical pluralism emerged as a persistent negative predictor of ART utilization among those needing it (AOR [95 % CI] = .556 [.344 - .899], p = .017). Use of traditional healthcare services by those who need ART may act as a barrier to treatment access. Effective intersectoral collaboration at community level is urgently needed.

Factors associated with late antiretroviral therapy initiation in Cameroon: a representative multilevel analysis

OBJECTIVES

Many people living with HIV/AIDS in resource-limited settings begin antiretroviral therapy (ART) at low CD4 counts. Here, we investigated the simultaneous effect of individual-, facility- and regional-level factors on late ART initiation.

METHODS

We conducted a survey in a nationally representative sample of 55 HIV treatment facilities in Cameroon. Medical records of 4935 patients >15 years of age who initiated ART in the month of October during the period 2007-10 were reviewed to gather individual characteristics. Late ART initiation was defined as CD4 count ≤ 100 cells/mm(3). Facility- and regional-level characteristics were also collected. Two-level regression logistic models were used to identify factors associated with late ART initiation.

RESULTS

Late ART initiation was associated with being a male younger than 45 years versus female younger than 45 years [adjusted OR (AOR) = 1.5, 95% CI: 1.3-1.7] and initiating ART in the period 2007-09 versus 2010 (AOR = 1.2, 95% CI: 1.0-1.4). Late initiation was more likely in central than in district hospitals (AOR = 1.3, 95% CI: 1.1-1.6) and in hospitals without a mother-to-child transmission programme (AOR = 1.9, 95% CI: 1.3-2.8). Living in a region with a higher comprehensive knowledge of HIV/AIDS was associated with not initiating ART late (AOR = 0.8, 95% CI: 0.6-1.0).

CONCLUSIONS

This study shows that risk factors associated with late ART initiation operate at multiple levels and that multilevel interventions are therefore necessary to promote earlier HIV testing and treatment.
