Factors associated with initiation of antiretroviral therapy in the advanced stages of HIV infection in six Ethiopian HIV clinics, 2012 to 2013

Barriers and enabling structural forces affecting access to antiretroviral therapy in Nigeria

BACKGROUND

Access to antiretroviral therapy (ART) helps to improve quality of life and reduces the spread of HIV. However, while a lot of studies focus on supply factors, such as resources for the purchase of antiretroviral drugs, demand and structural forces are not given much emphasis. In this paper it is argued that structural forces shape the way people access antiretroviral therapy in Nigeria.

METHODS

A Grounded Theory methodology was undertaken in the research. Semi structured qualitative interviews were administered to select people living with HIV/AIDS in Nigeria. This was facilitated by the Network of People Living with HIV/AIDS in Nigeria (NEPWHAN) to understand their perspectives with regard to barriers and enablers to ART access in Nigeria. Thirty persons living with HIV/AIDS were interviewed and recorded. The interview recordings were transcribed and coded using a constructionist epistemological approach. This was triangulated with results of preliminary and secondary literature review analysis.

RESULTS

In this research, the participants discussed structural forces (barriers and enablers) that influenced how they accessed ART. These included economic factors such as poverty that enabled transactional sex. Unequal gender relations and perceptions influenced how they accessed ART. The participants' belief in 'God' and religious activities such as 'prayer' and the use of 'traditional medicine' had an impact on how and when they accessed ART. Political activity at the international, national, and local levels influenced access to ART as well as resources. The individual's familial, social, and organisational connections also influenced their ease of accessing ART.

CONCLUSIONS

This study identifies structural forces that affect access to antiretroviral therapy and provides recommendations on how they can be harnessed to enable improved access to ART and consequently improved health.

Factors associated with late initiation of antiretroviral therapy in Iran's HIV/AIDS surveillance data

Early initiation of Antiretroviral Treatment (ART) in HIV patients is essential for effectively suppressing the viral load and prognosis. This study utilized National HIV/AIDS Surveillance Data in Iran to identify factors associated factors with the duration to initiate ART. This hybrid cross-sectional historical cohort study was conducted on Iran's National HIV/AIDS Surveillance Data from 2001 to 2019. Sociodemographic characteristics, route of transmission, HIV diagnosis date, and ART initiation date were collected. Multivariable linear and quantile regression models were employed to analyze the duration to initiate ART by considering predictor variables. This study included 17,062 patients (mean age 34.14 ± 10.77 years, 69.49% males). Multivariate quantile regression coefficients varied across different distributions of the dependent variable (i.e., duration to initiate ART) for several independent variables. Generally, male gender, injecting drug use (IDU), and having an HIV-positive spouse were significantly associated with an increased duration to initiate ART (p < 0.05). However, a significant decrease was observed in older patients, those with a university level education, men who had sex with men (MSM), and patients diagnosed after 2016 (p < 0.05). Despite improvements in the duration to initiate ART after implementing the WHO's 2016 program in Iran, various sociodemographic groups were still vulnerable to delayed ART initiation in the region. Therefore, programs including early testing, early ART initiation, active care, educational and cultural interventions, and appropriate incentives are required for these groups.

Current ART, determinants for virologic failure and implications for HIV drug resistance: an umbrella review

OBJECTIVE

The purpose of this study is to investigate the incidence of determinants for virologic failure and to identify predisposing factors to enhance treatment efficacy. Tackling this global public health issue is the key to reducing the rate of virological failure and increasing the success of treatment for those living with HIV.

METHODS

This umbrella review delves into various aspects of current anti-retroviral therapy (ART) which is the primary treatment for human immunodeficiency virus (HIV) infection. Comprehensive searches were conducted in online databases including PubMed, Embase, Scopus, and Web of Science, up to May 26, 2023. Following the screening and selection of relevant articles, eligible articles were included in the data extraction. This study adhered to the PRISMA guideline to report the results and employed the NIH quality and bias risk assessment tool to ensure the quality of included studies.

RESULTS

In total, 40 review studies published from 2015 to 2023 were included. The bulk of these studies concurred on several major factors contributing to HIV drug resistance and virological failure. Key among these were medication adherence, baseline and therapeutic CD4 levels, the presence of co-infections, and the advanced clinical stage of the infection.

CONCLUSION

The resistance to HIV drugs and instances of determinants for virologic failure have a profound impact on the life quality of those infected with HIV. Primary contributors to this scenario include insufficient adherence to treatment, decreased CD4 T-cell count, elevated viral levels, and certain treatment regimens. Implementing appropriate interventions could address these issues. Sub-Saharan Africa exhibits elevated rates of determinants for virologic failure, attributed to the delay in HIV testing and diagnosis, and late initiation of antiretroviral therapy (ART). It is essential to undertake further research aimed at enhancing the detection of resistance in HIV patients and mitigating viral failure by addressing these underlying causes.

Perspectives of people living with HIV on barriers to timely ART initiation following referral for antiretroviral therapy: A qualitative study at an urban HIV clinic in Kampala, Uganda

Early initiation of antiretroviral therapy (ART) after HIV diagnosis prevents HIV transmission, progression of HIV to AIDS and improves quality of life. However, little is known about the barriers to timely ART initiation among patients who test HIV positive in settings different from where they will receive HIV treatment, hence are referred in the routine setting. Therefore, we explored the perspectives of people living with HIV on barriers faced to initiate ART following HIV testing and referral for treatment. In this qualitative study, we purposively sampled and enrolled 17 patients attending the Mulago ISS clinic. We selected patients (≥18 years) who previously were received as referrals for HIV treatment and had delayed ART initiation, as ascertained from their records. We conducted in-depth interviews, which were audio recorded, transcribed and translated. We used Atlas.ti version 9 software for data management. Data analysis followed thematic and framework analysis techniques and we adopted the socio-ecological model to categorize final themes. Key themes were found at organizational level including; negative experiences at the place of HIV diagnosis attributed to inadequate counselling and support, unclear communication of HIV-positive results and ambiguous referral procedures; and, long waiting time when patients reached the HIV clinic. At individual level, the themes identified were; immediate denial with late acceptance of HIV-positive results attributed to severe emotional and psychological distress at receiving results, fear of perceived side effects and long duration on ART. At interpersonal level, we found that anticipated and enacted stigma after HIV diagnosis resulted in non-disclosure, discrimination and lack of social support. We found that challenges at entry (during HIV test) and navigation of the HIV care system in addition to individual and interpersonal factors contributed to delayed ART initiation. Interventions during HIV testing would facilitate early ART initiation among patients referred for HIV care.

Predictors of delayed Anti-Retroviral Therapy initiation among adults referred for HIV treatment in Uganda: a cross-sectional study

BACKGROUND

Uganda's current guidelines recommend immediate initiation of Anti-Retroviral Therapy (ART) for persons living with HIV in order to reduce HIV/AIDS related morbidity and mortality. However, not all eligible PLHIV initiate ART within the recommended time following HIV diagnosis. We assessed the prevalence and factors associated with delayed ART initiation among PLHIV referred for ART initiation, five years since rolling out the test and treat guidelines.

METHODS

In this cross-sectional study, we enrolled adult patients referred to Mulago Immune Suppressive Syndrome (Mulago ISS) clinic for ART initiation from January 2017 to May 2021. We collected data on socio-demographics, HIV diagnosis and referral circumstances, and time to ART initiation using a questionnaire. The outcome of interest was proportion of patients that delayed ART, defined as spending more than 30 days from HIV diagnosis to ART initiation. We performed multivariable logistic regression and identified significant factors.

RESULTS

A total of 312 patients were enrolled of which 62.2% were female. The median (inter-quartile range [IQR]) age and baseline CD4 count of the patients were 35 (28-42) years and 315 (118.8-580.5) cells/μL respectively. Forty-eight (15.4%) patients delayed ART initiation and had a median (IQR) time to ART of 92 (49.0-273.5) days. The factors associated with delayed ART initiation were; 1) having had the HIV diagnosis made from a private health facility versus public, (adjusted odds ratio [aOR] = 2.4 (95% confidence interval [CI] 1.1-5.5); 2) initial denial of positive HIV test results, aOR = 5.4 (95% CI: 2.0-15.0); and, 3) having not received a follow up phone call from the place of HIV diagnosis, aOR = 2.8 (95% CI: 1.2-6.8).

CONCLUSION

There was significant delay of ART initiation among referred PLHIV within 5 years after the rollout of test and treat guidelines in Uganda. Health system challenges in the continuity of HIV care services negatively affects timely ART initiation among referred PLHIV in Uganda.

Antiretroviral therapy initiation and outcomes of hospitalized HIV-infected patients in Uganda—An evaluation of the HIV test and treat strategy

Background

Uganda adopted the HIV Test and Treat in 2016. There is paucity of data about its implementation among hospitalized patients. We aimed to determine the proportion of patients initiating anti-retroviral therapy (ART) during hospitalization, barriers and mortality outcome.

Methods

In this mixed methods cohort study, we enrolled hospitalized patients with a recent HIV diagnosis from three public hospitals in Uganda. We collected data on clinical characteristics, ART initiation and reasons for failure to initiate ART, as well as 30 day outcomes. Healthcare workers in-depth interviews were also conducted and data analyzed by sub-themes.

Results

We enrolled 234 patients; females 140/234 (59.8%), median age 34.5 years (IQR 29–42), 195/234 (83.7%) had WHO HIV stage 3 or 4, and 74/116 (63.8%) had CD4 ≤ 200 cell/μL. The proportion who initiated ART during hospitalization was 123/234 (52.6%) (95% CI 46.0–59.1), of these 35/123 (28.5%) initiated ART on the same day of hospitalization, while 99/123 (80.5%) within a week of hospitalization. By 30 days 34/234 (14.5%) (95% CI 10.3–19.7) died. Patients residing ≥ 35 kilometers from the hospital were more likely not to initiate ART during hospitalization, [aRR = 1.39, (95% CI 1.22–1.59). Inadequate patient preparation for ART initiation and advanced HIV disease were highlighted as barriers of ART initiation during hospitalization.

Conclusion

In this high HIV prevalence setting, only half of newly diagnosed HIV patients are initiated on ART during hospitalization. Inadequate pre-ART patient preparation and advanced HIV are barriers to rapid ART initiation among hospitalized patients in public hospitals.

Risk factors for late linkage to care and delayed antiretroviral therapy initiation amongst HIV infected adults in sub-Saharan Africa: a systematic review and meta-analyses

BACKGROUND

Late treatment initiation threatens the clinical and public health benefits of antiretroviral therapy (ART). Quantitative synthesises of the existing evidence related to this is lacking in sub-Saharan Africa (SSA), which would help ascertain the best evidence-based interventions. This review aimed to systematically synthesise the available literature on factors affecting linkage to care and ART initiation amongst HIV-infected adults in SSA.

METHODS

Systematic searches were undertaken on four databases to identify observational studies investigating factors affecting both HIV care outcomes amongst adults (age ≥19 years) in SSA, and were published between January 1, 2015 and June 1, 2021. RevMan-5 software was used to conduct meta-analyses and Mantel-Haenszel statistics to pool outcomes with 95% confidence interval and <0.05 level of significance.

RESULTS

Forty-six studies were included in the systematic review, of which 18 fulfilled requirements for meta-analysis. In both narrative review and meta-analyses, factors related to health care delivery, individual perception and sociodemographic circumstances were associated with late linkage to care and delays in ART initiation.

CONCLUSION

This review identified a range of risk factors for late linkage to care and delayed ART initiation amongst HIV-infected adults in SSA. We recommend implementation of patient-centred intervention approaches to alleviate these barriers.

Effect of universal test and treat on retention and mortality among people living with HIV-infection in Uganda: An interrupted time series analysis

Background

Few studies have analysed the effect of HIV universal test and treat (UTT) on retention and mortality among people living with HIV (PLHIV) in routine care. We examined six-month retention and mortality at 11 health facilities (HFs) run by a large NGO, The AIDS Support Organisation (TASO), before and after UTT.

Methods

We used a quasi-experimental study using patient data extracted from 11 TASO HFs. Two periods, one before UTT (2015–2016) and the other during UTT (2017–2018) were compared. The primary outcome was six-month retention defined as the proportion of PLHIV who were alive and in care at six months from enrolment. The secondary outcome was six-month mortality defined as the proportion of PLHIV who died within six months from enrolment. We performed an interrupted time series analysis using graphical aids to study trends in six-month retention and mortality and a segmented regression to evaluate the effect of UTT. We used a generalized linear mixed model (GLMM) and generalized estimating equations (GEE) to account for facility-level clustering.

Results

Of the 20,171 PLHIV registered between 2015 and 2018 and included in the analysis, 12,757 (63.2%) were enrolled during the UTT period. 5256/7414 (70.9%) of the pre-UTT period compared to 12239/12757 (95.9%) of the UTT were initiated on ART treatment with 6 months from enrolment. The median time from enrolment to initiating ART was 14 (interquartile range (IQR): 0–31) days for the pre-UTT compared to 0 (IQR: 0–0) days for the UTT period. The median age at enrolment was 32.5 years for the pre-UTT and 35.0 years for the UTT period. Overall, the six-month retention just after scale-up of UTT, increased by 9.2 percentage points (p = 0.002) from the baseline value of 82.6% (95% CI: 77.6%-87.5%) but it eventually decreased at a rate 1.0 percentage point (p = 0.014) for cohorts recruited each month after UTT. The baseline six-month mortality was 3.3% (95% CI: 2.4%-4.2%) and this decreased by 1.6 percentage points (p = 0.003) immediately after UTT. The six-month mortality continued decreasing at a rate of 0.1 percentage points (p = 0.002) for cohorts enrolled each month after UTT. Retention differed between some health facilities with Rukungiri HF having the highest and Soroti the lowest retention. Retention was slightly higher among males and younger people. Mortality was highest among people aged 50 years and more. The effect of UTT on retention and mortality was similar across sex and age groups.

Conclusion

Overall, UTT significantly led to an immediate increase in retention and decrease in mortality among PLHIV enrolled in HIV care from 11 HFs run by TASO in Uganda. However, retention (and mortality) significantly decreased for cohorts enrolled each month after UTT. Retention was highest in Rukungiri and lowest in Soroti HFs and slightly higher in males and younger people. Mortality was highest in older patients and lowest in adolescents. We recommend for innovative interventions to improve the overall retention particularly in facilities reporting low retention in order to achieve the UNAIDS 2030 target of 95-95-95.

Burden and Associated Factors of Virological Failure Among People Living with HIV in Sub-Saharan Africa: A Systematic Review and Meta-Analysis

United Nations program on HIV/AIDS 90-90-90 ambitious goal recommends 90% of people living with HIV and taking antiretroviral therapy should achieve viral suppression by 2020. However, virological failure is still a global public health problem, especially in sub-Saharan African countries. Thus, this systematic review and meta-analysis aimed at estimating the burden of virological failure and its associated factors among peoples living with HIV in sub-Saharan Africa. We searched Google Scholar, PubMed, Cochrane Library, and Scopus for studies that reported virologic failure and its associated factors. I-squared statistics and Egger's statistical test were used to detect heterogeneity and publication bias respectively. The pooled prevalence of virological failure was estimated using the DerSimonian-Laird random-effects model. Sensitivity analysis was done to check the presence of outlier results included in the studies. The estimated pooled prevalence of virological failure was 1.7.25%. Lower Adherence to ART drugs,longer ART duration, lower CD4 count,and being co-infected with TB were significantly associated with the pooled estimate of virological failure.Virological failure was found to be high in sub-Saharan Africa. Adherence, duration of ART, CD4 + count, and TB co-infection were the significant factors associated with the pooled estimate of virological failure. Therefore, to achieve the 90-90-90 target and sustainable development goal 3 policymakers should design mechanisms to improve ART adherence, and early detecting and prevent opportunistic infections such as TB.

Longitudinal analysis of sociodemographic, clinical and therapeutic factors of HIV-infected individuals in Kinshasa at antiretroviral therapy initiation during 2006-2017

Background

The benefits of antiretroviral therapy (ART) underpin the recommendations for the early detection of HIV infection and ART initiation. Late initiation (LI) of antiretroviral therapy compromises the benefits of ART both individually and in the community. Indeed, it promotes the transmission of infection and higher HIV-related morbidity and mortality with complicated and costly clinical management.

This study aims to analyze the evolutionary trends in the median CD4 count, the median time to initiation of ART, the proportion of patients with advanced HIV disease at the initiation of ART between 2006 and 2017 and their factors.

Methods and findings

HIV-positive adults (≥ 16 years old) who initiated ART between January 1, 2006 and December 31, 2017 in 25 HIV care facilities in Kinshasa, the capital of DRC, were eligible. The data were processed anonymously. LI is defined as CD4≤350 cells/μl and/or WHO clinical stage III or IV and advanced HIV disease (AHD), as CD4≤200 cells/μl and/or stage WHO clinic IV. Factors associated with advanced HIV disease at ART initiation were analyzed, irrespective of year of enrollment in HIV care, using logistic regression models.

A total of 7278 patients (55% admitted after 2013) with an average age of 40.9 years were included. The majority were composed of women (71%), highly educated women (68%) and married or widowed women (61%). The median CD4 was 213 cells/μl, 76.7% of patients had CD4≤350 cells/μl, 46.1% had CD4≤200 cells/μl, and 59% of patients were at WHO clinical stages 3 or 4. Men had a more advanced clinical stage (p <0.046) and immunosuppression (p<0.0007) than women.

Overall, 70% of patients started ART late, and 25% had AHD. Between 2006 and 2017, the median CD4 count increased from 190 cells/μl to 331 cells/μl (p<0.0001), and the proportions of patients with LI and AHD decreased from 76% to 47% (p< 0.0001) and from 18.7% to 8.9% (p<0.0001), respectively.

The median time to initiation of ART after screening for HIV infection decreased from 40 to zero months (p<0.0001), and the proportion of time to initiation of ART in the month increased from 39 to 93.3% (p<0.0001) in the same period.

The probability of LI of ART was higher in married couples (OR: 1.7; 95% CI: 1.3–2.3) (p<0.0007) and lower in patients with higher education (OR: 0.74; 95% CI: 0.64–0.86) (p<0.0001).

Conclusion

Despite increasingly rapid treatment, the proportions of LI and AHD remain high. New approaches to early detection, the first condition for early ART and a key to ending the HIV epidemic, such as home and work HIV testing, HIV self-testing and screening at the point of service, must be implemented.

Time to Antiretroviral Therapy Initiation and Its Predictors Among Newly Diagnosed HIV-Positive People in Nekemte Town, Western Ethiopia: Claim of Universal Test and Treat

Background

HIV continuum of care demands early ART initiation for all HIV-infected individuals. Early ART initiation reduces onward HIV transmission facilitating rapid viral suppression. Despite this, delayed ART use is a challenge among newly diagnosed HIV-positive individuals, and there is limited evidence on time to ART initiation among this group in Ethiopia. Thus, this study aimed to assess time to ART initiation and its predictors among newly diagnosed HIV-positive individuals in Nekemte town, Western Ethiopia.

Methods

An institution-based retrospective follow-up study was conducted on 518 newly diagnosed HIV-positive people from September 5, 2016 to December 20, 2020 at Nekemte town, Western Ethiopia. Data were collected from ART intake forms, registration log books and patient charts. The collected data were entered into Epi Data version 3.1 and STATA version 14.0 was used for analysis. Survival probability was checked graphically by Kaplan–Meier curve and statistically by Log rank test. Both bivariable and multivariable Cox Proportional hazards regression models were conducted to identify the predictors of ART initiation. Hazard ratio with 95% CI and p-value of <0.05 was used to declare a statistical significance.

Results

By the end of the follow-up, 371 (71.6%) individuals had initiated ART with an overall incidence rate of 51.9 per 1000 [95% CI: 54.07–66.32] person days; median time to ART initiation was 4 [IQR: 1–9] days. Being female (AHR = 1.33, 95% CI: 1.06–1.67), urban dwellers (AHR = 2.02, 95% CI: 1.37–2.97), having baseline OIs (AHR = 1.62, 95% CI: 1.60–4.30); being tested via VCT (AHR = 1.33, 95% CI: 1.02–1.74); linked from OPD (AHR = 0.64, 95% CI: 0.47–0.85); disclosing HIV sero-status (AHR = 2.07, 95% CI: 1.17–3.68); and college and above education level (AHR = 1.43, 95% CI: 1.00–2.0) were identified as significant predictors of early initiation of ART.

Conclusion

The proportion and incidence of ART initiation was high; a short median time to ART initiation was revealed in this study. Strictly screening OIs, encouraging HIV sero-status disclosure and voluntary HIV testing are recommended to increase early ART initiation.

Improvement in depressive symptoms after antiretroviral therapy initiation in people with HIV in Rakai, Uganda

Depression is common following HIV infection and often improves after ART initiation. We aimed to identify distinct dimensions of depression that change following ART initiation in persons with HIV (PWH) with minimal comorbidities (e.g., illicit substance use) and no psychiatric medication use. We expected that dimensional changes in improvements in depression would differ across PWH. In an observational cohort in Rakai, Uganda, 312 PWH (51% male; mean age = 35.6 years) completed the Center for Epidemiologic Studies-Depression (CES-D) scale before and up to 2 years after ART initiation. Twenty-two percent were depressed (CES-D scores ≥ 16) pre-ART that decreased to 8% after ART. All CES-D items were used in a latent class analysis to identify subgroups with similar change phenotypes. Two improvement phenotypes were identified: affective-symptom improvement (n = 58, 19%) and mixed-symptom improvement (effort, appetite, irritability; n = 41, 13%). The affect-improvement subgroup improved on the greatest proportion of symptoms (76%). A third subgroup was classified as no-symptom changes (n = 213, 68%) as they showed no difference is symptom manifestation from baseline (93% did not meet depression criteria) to post-ART. Factors associated with subgroup membership in the adjusted regression analysis included pre-ART self-reported functional capacity, CD4 count, underweight BMI, hypertension, female sex(P's < 0.05). In a subset of PWH with CSF, subgroup differences were seen on Aβ-42, IL-13, and IL-12. Findings support that depression generally improves following ART initiation; however, when improvement is seen the patterns of symptom improvement differ across PWH. Further exploration of this heterogeneity and its biological underpinning is needed to evaluate potential therapeutic implications of these differences.

Psychological Distress and Its Correlates among Newly Diagnosed People Living with HIV in Northwest Ethiopia: Ordinal Logistic Regression Analyses

Background

Although there is a high burden of HIV in sub-Saharan Africa (SSA), studies on mental health issues among people living with HIV are scarce. The study addressed the transition to "test and treat" guidelines for HIV, which makes it unique regarding its evaluation of psychological distress amongst newly initiated people living with HIV in the test and treat era.

Methods

We conducted a cross-sectional survey of 689 people newly diagnosed with HIV. Symptoms of psychological distress were measured using the Kessler-10 psychological distress assessment scale. Factors associated with psychological distress were captured using interviewer-administered questionnaires. Ordinal logistic regression analyses were employed to identify predictors of psychological distress.

Results

The magnitude of psychological distress was 58.63% (95% CI = 55.2%-62.3%). The severity of the psychological distress of which, 17.42% had severe distress. Psychological distress was observed more among female patients (β = 0.47, AOR = 1.59, 95% CI = 1.12, 2.27), patients presented with opportunistic infections (β = 0.50, AOR = 1.65, 95% CI = 1.03, 2.66) and being non-working functional status (β = 0.99, AOR = 2.70, 95% CI = 1.64, 4.45). Moreover, patients who were malnourished (β = 0.46, AOR = 1.58, 95% CI = 1.09, 2.26), having good level of knowledge on HIV prevention (β = 0.59, 95% CI = 0.55, 0.39, 0.78), presented with sexually transmitted infection (β = 0.48, AOR = 1.61, 95% CI = 1.01, 2.58), history of alcohol use (β = 0.44, AOR = 1.55, 95% CI = 1.09, 2.21), perceived stigma (β = 0.08, AOR = 1.09 95% CI = 1.04, 1.15) and treated in health centers (β = 0.55, AOR = 1.74, 95% CI = 1.25, 2.41) had higher odds of psychological distress.

Conclusion

The large majority of newly diagnosed HIV patients suffered from psychological distress. An increased vulnerability was observed among females, those with opportunistic and sexually transmitted infections, those having poor functional status and malnourished. Furthermore, HIV patients treated in health centers, those who had history of alcohol use and patients with high level of HIV related stigma are more negatively affected by the HIV diagnosis. Hence, all intervention strategies should target all the identified predictors.

Same-day antiretroviral treatment (ART) initiation and associated factors among HIV positive people in Northwest Ethiopia: baseline characteristics of prospective cohort

Background

Despite a well-established fact that same-day or rapid ART initiation after a positive HIV test result is vital for faster viral suppression and for prevention of further sexual transmissions of HIV, there is a paucity of evidence on the uptake of same-day ART initiation among newly HIV diagnosed people in Northwest, Ethiopia.

Methods

A cross-sectional study was conducted between December 1st, 2018 and July 30, 2019. About 759 newly HIV diagnosed adults were recruited from 24 health facilities. Data were collected using interviewer-administered questionnaire. Data were entered using EPI-Data and exported to SPSS and STATA software for further analysis. Bivariate logistic regression was used to select candidate variables at p-value less than 0.25 for multivariate logistic regression. Then adjusted odds ratio with 95% Confidence Interval (CI) at p-value of less than 0.05 was used to declare the statistical associations between the dependent and independent variables.

Result

Magnitude of same-day ART initiation was 318 (41.90%) [(95% CI, 38.2–45.20%)]. Factors associated with same-day ART initiation were: Patients resided in West Gojjam Zone were 2.04 times more likely to initiate same-day ART compared to those in Bahir Dar city administration [AOR = 2.04 (1.04–3.97)], patients in the health centers were 3.06 times more likely to initiate same-day ART initiation compared to those in the hospitals [AOR = 3.06 (1.90–4.92)] and Patients who were diagnosed their HIV status at the same health facility where they linked for ART were 2.16 times more likely to initiate ART at the same-day of diagnosis [AOR = 2.16 (91.24–3.74)]. Moreover, patients with no opportunistic infection [AOR = 2.08 (1.04–4.19)] and pregnant women [AOR = 3.97 (1.78–8.87)] were more likely to initiate ART same-day of diagnosis.

Conclusions

Same-day ART initiation was low among HIV patients in Ethiopia. Patients attending their treatment at hospitals and those from big city (Bahir Dar) were less likely to initiate same-day ART. Clinical factors such as having opportunistic infections and non-pregnancy status affected the immediate initiation of treatment. HIV positive people who seek care in hospitals and those tested HIV positive from another health facilities in which they did not intend to continue their ART follow-up care need special attention.

Substance use service availability in HIV treatment programs: Data from the global IeDEA consortium, 2014-2015 and 2017

BACKGROUND

Substance use is common among people living with HIV and has been associated with suboptimal HIV treatment outcomes. Integrating substance use services into HIV care is a promising strategy to improve patient outcomes.

METHODS

We report on substance use education, screening, and referral practices from two surveys of HIV care and treatment sites participating in the International epidemiology Databases to Evaluate AIDS (IeDEA) consortium. HIV care and treatment sites participating in IeDEA are primarily public-sector health facilities and include both academic and community-based hospitals and health facilities. A total of 286 sites in 45 countries participated in the 2014-2015 survey and 237 sites in 44 countries participated in the 2017 survey. We compared changes over time for 147 sites that participated in both surveys.

RESULTS

In 2014-2015, most sites (75%) reported providing substance use-related education on-site (i.e., at the HIV clinic or the same health facility). Approximately half reported on-site screening for substance use (52%) or referrals for substance use treatment (51%). In 2017, the proportion of sites providing on-site substance use-related education, screening, or referrals increased by 9%, 16%, and 8%, respectively. In 2017, on-site substance use screening and referral were most commonly reported at sites serving only adults (compared to only children/adolescents or adults and children/adolescents; screening: 86%, 37%, and 59%, respectively; referral: 76%, 47%, and 46%, respectively) and at sites in high-income countries (compared to upper middle income, lower middle income or low-income countries; screening: 89%, 76%, 68%, and 45%, respectively; referral: 82%, 71%, 57%, and 34%, respectively).

CONCLUSION

Although there have been increases in the proportion of sites reporting substance use education, screening, and referral services across IeDEA sites, gaps persist in the integration of substance use services into HIV care, particularly in relation to screening and referral practices, with reduced availability for children/adolescents and those receiving care within resource-constrained settings.

ART use and associated factors among HIV positive caregivers of orphans and vulnerable children in Tanzania

Background

Utilization of antiretroviral therapy (ART) is crucial for better health outcomes among people living with the human immunodeficiency virus (PLHIV). Nearly 30% of the 1.6 million PLHIV in Tanzania are not on treatment. Since HIV positive status is the only eligibility criterion for ART use, it is critical to understand the obstacles to ART access and uptake to reach universal coverage of ART among PLHIV. For the caregivers of orphans and vulnerable children (OVC) LHIV and not on ART, attempts to identify them and ensure that they initiate and continue using ART is critical for their wellbeing and their ability to care for their children.

Methods

Data are from the community-based, United States Agency for International Development (USAID)-funded Kizazi Kipya project that aims at scaling up the uptake of HIV/AIDS and other health and social services by orphans and vulnerable children (OVC) and their caregivers. HIV positive caregivers of OVC who were enrolled in the USAID Kizazi Kipya project between January 2017 and June 2018 were included in this cross-sectional study. The caregivers were drawn from 11 regions: Arusha, Iringa, Katavi, Kigoma, Mara, Mbeya, Morogoro, Ruvuma, Simiyu, Singida, and Tanga. The outcome variable was ART status (either using or not), which was enquired of each OVC caregiver LHIV at enrollment. Data analysis involved multivariable analysis using random-effects logistic regression to identify correlates of ART use.

Results

In total, 74,999 caregivers living with HIV with mean age of 44.4 years were analyzed. Of these, 96.4% were currently on ART at enrollment. In the multivariable analysis, ART use was 30% lower in urban than in rural areas (adjusted odds ratio (OR) = 0.70, 95% confidence interval (CI) 0.61–0.81). Food security improved the odds of being on ART (OR = 1.29, 95% CI 1.15–1.45). Disabled caregivers were 42% less likely than non-disabled ones to be on ART (OR = 0.58, 95% CI 0.45–0.76). Male caregivers with health insurance were 43% more likely than uninsured male caregivers to be on ART (OR = 1.43, 95% CI 1.11–1.83). Caregivers aged 40–49 years had 18% higher likelihood of being on ART than the youngest ones. Primary education level was associated with 26% increased odds of being on ART than no education (OR = 1.26, 95% CI 1.13–1.41).

Conclusions

Although nearly all the caregivers LHIV in the current study were on ART (96.4%), more efforts are needed to achieve universal coverage. The unreached segments of the population LHIV, even if small, may lead to worse health outcomes, and also spur further spread of the HIV epidemic due to unachieved viral suppression. Targeting caregivers in urban areas, food insecure households, who are uninsured, and those with mental or physical disability can improve ART coverage among caregivers LHIV.

Advanced HIV Disease among Males and Females Initiating HIV Care in Rural Ethiopia

Despite recommendations for rapidly initiating HIV treatment, many persons in sub-Saharan Africa present to care with advanced HIV disease. Baseline survey and clinical data were collected on 1799 adults newly enrolling at 32 district hospitals and local health HIV clinics in rural Ethiopia. Among those with complete HIV disease information, advanced HIV disease (defined as CD4 count <200 cells/mm³ or World Health Organization [WHO] HIV clinical stage III or IV disease) was present in 66% of males and 56% of females (P < .001). Males (compared to females) had lower CD4 counts (287 cells/mm³ versus 345 cells/mm³), lower body mass index (19.3 kg/m² versus 20.2 kg/m²), and more WHO stage III or IV disease (46% versus 37%), (P < .001). Men reported more chronic diarrhea, fevers, cough, pain, fatigue, and weight loss (P < .05). Most initiating care in this resource-limited setting had advanced HIV disease. Men had poorer health status, supporting the importance of earlier diagnosis, linkage to care, and initiation of antiretroviral therapy.

Long-Term Benefits of Rapid Antiretroviral Therapy Initiation in Reducing Medical and Overall Health Care Costs Among Medicaid-Covered Patients with Human Immunodeficiency Virus

BACKGROUND

New guidelines for the treatment of human immunodeficiency virus (HIV) suggest that morbidity and mortality could be reduced if antiretroviral therapy (ART) was initiated immediately after diagnosis, regardless of CD4 cell count.

OBJECTIVE

To assess real-world time to ART initiation and describe medical, pharmacy, and total health care costs in the 6-, 12-, 24-, and 36-month periods after HIV diagnosis based on time to ART initiation among Medicaid-covered patients.

METHODS

Multistate Medicaid data (January 2012-March 2017) was used to identify adults with HIV-1 initiating ART ≤ 360 days of initial HIV-1 diagnosis. People living with HIV (PLWH) were sorted into mutually exclusive cohorts based on time from diagnosis to ART initiation (≤ 14 days, > 14 to ≤ 60 days, > 60 to ≤ 180 days, and > 180 to ≤ 360 days). ART regimen had to include a protease inhibitor, an integrase strand transfer inhibitor, or a non-nucleoside reverse transcriptase inhibitor, with ≥ 2 nucleoside reverse transcriptase inhibitors. Medical, pharmacy, and total health care costs in the 6, 12, 24, and 36 months following HIV diagnosis were stratified by timeliness of ART initiation.

RESULTS

Of 974 patients, 347 (35.6%) initiated ART > 360 days after diagnosis and were excluded. Among the remaining 627 eligible patients, mean age was 39.9 years, 42.7% were female, and 53.9% were black. Among them, 128 (20.4%) were treated ≤ 14 days, 228 (36.4%) between > 14 and ≤ 60 days, 163 (26.0%) between > 60 and ≤ 180 days, and 108 (17.2%) between > 180 and ≤ 360 days. Among patients treated ≤ 180 days, 4.6% had ≥ 1 opportunistic infection in the 6-month period before ART initiation; this proportion reached 5.6% for patients treated >180 and ≤ 360 days. Over the 6-, 12-, 24-, and 36-month periods after diagnosis, per-patient-per-month (PPPM) medical costs were lower for patients who initiated ART ≤ 14 days than for those who initiated > 180 and ≤ 360 days after diagnosis (6 months: $1,611 [≤ 14 days] vs. $3,008 [> 180 and ≤ 360 days]; 12 months: $1,188 vs. $2,110; 24 months: $754 vs. $1,368; 36 months: $651 vs. $1,196). Over the same periods, medical costs generally accounted for > 50% of total health care costs for patients who initiated ART between > 60 and ≤ 180 days and > 180 and ≤ 360 days and for 30%-40% of total health care costs for patients treated ≤ 14 days and between > 14 and ≤ 60 days. Total PPPM health care costs increased with delay of ART initiation in the 36-month period after diagnosis ($2,058 [treated ≤ 14 days] vs. $2,310 [treated between > 180 and ≤ 360 days]).

CONCLUSIONS

In this study from 2012 to 2017 of Medicaid PLWH treated with ART, 20.4% initiated ART ≤14 days of HIV diagnosis. Patients with delayed ART initiation accumulated more total health care costs in the 36-month period after HIV diagnosis than those initiated within 14 days, highlighting the long-term benefit of rapid ART initiation. An important opportunity remains to engage PLWH in care more rapidly.

HIV/AIDS treatment failure and associated factors in Ethiopia: meta-analysis

Background

The national burden of human immunodeficiency virus treatment failure and associated factors in the Ethiopian context is required to provide evidence towards a renewed ambitious future goal.

Methods

We accessed Ethiopian Universities’ online repository library, Google Scholar, PubMed, Web of Science, and Scopus to get the research articles. We run I-squared statistics to see heterogeneity. Publication bias was checked by using Egger’s regression test. The pooled prevalence was estimated using the DerSimonian-Laird random-effects model. We employed the sensitivity analysis to see the presence of outlier result in the included studies.

Results

The overall human immunodeficiency treatment failure was 15.9% (95% confidence interval: 11.6–20.1%). Using immunological, virological, and clinical definition, human immunodeficiency treatment failure was 10.2% (95% confidence interval: 6.9–13.6%), 5.6% (95% confidence interval: 2.9–8.3%), and 6.3% (95% confidence interval: 4.6–8.0%), respectively. The pooled effects of World Health Organization clinical stage III/IV (Adjusted Odd Ratio = 1.9; 95% CI: 1.3–2.6), presence of opportunistic infections (Adjusted Odd Ratio = 1.8; 95% CI: 1.2–2.4), and poor adherence to highly active antiretroviral therapy (Adjusted Odd Ratio = 8.1; 95% CI: 4.3–11.8) on HIV treatment failure were estimated.

Conclusions

Human immunodeficiency virus treatment failure in Ethiopia found to be high. Being on advanced clinical stage, presence of opportunistic infections, and poor adherence to highly active antiretroviral therapy were the contributing factors of human immunodeficiency virus treatment failure. Human immunodeficiency virus intervention programs need to address the specified contributing factors of human immunodeficiency virus treatment failure. Behavioral intervention to prevent treatment interruption is required to sustain human immunodeficiency virus treatment adherence.

Prevalência do alto risco de complicações clínicas associadas ao óbito por Aids

Resumo Objetivo: Investigar a prevalência do alto risco entre casos de óbitos a partir da classificação de risco de complicações clínicas associadas a aids e sua relação com variáveis sociodemográficas e terapêuticas. Métodos: Estudo epidemiológico, retrospectivo, envolvendo 80 casos de óbito por aids ocorridos entre 2007 e 2015 em um Estado do Nordeste brasileiro. A estratificação do risco considerou indicadores de acompanhamento obtidos no diagnóstico da infecção, atribuindo-se valores de 1,2 para carga viral, e 1,2 e 3 aos indicadores de linfócitos T CD4+, quantidade de doenças oportunistas, manifestações clínicas e doenças crónicas, com escore variando entre 5 e 14. Quanto maior esse escore, maior o risco para complicações clínicas. Os dados foram analisados estimando a prevalência e razão de prevalência para o alto risco, seguido do método de Weight of Evidence e estatística D de Somers. Resultados: Dos 80 casos estudados, 51,2% foram alocados no estrato de alto risco. O registro de antecedentes psiquiátricos aumentou em 2 vezes a prevalência para o alto risco e a faixa etária apresentou forte relação com esse estrato. A contagem de linfócitos T-CD4+, doenças oportunistas e manifestações clínicas foram os indicadores que apresentaram maior força de associação com a estratificação de risco. Conclusão: O estudo mostrou a prevalência do alto risco para o desenvolvimento de complicações clínicas, maior força associativa nos indicadores LT-CD4+, doenças oportunistas e manifestações clínicas com escore de risco proposto. Estes resultados sugerem a necessidade de atenção especial dos serviços de atenção especializada aos indivíduos acompanhados em nível ambulatorial.

Psychosocial Factors Associated with Food Insufficiency Among People Living with HIV/AIDS (PLWH) Initiating ART in Ethiopia

Food insufficiency is associated with suboptimal HIV treatment outcomes. Less is known about psychosocial correlates of food insufficiency among PLWH. This sample includes 1176 adults initiating antiretroviral therapy at HIV clinics in Ethiopia. Logistic regression modeled the association of psychological distress, social support, and HIV-related stigma with food insufficiency. Among respondents, 21.4% reported frequent food insufficiency. Psychological distress [adjusted odds ratio (aOR) 2.61 (95% CI 1.79, 3.82)], low social support [aOR 2.20 (95% CI 1.57, 3.09)] and enacted stigma [aOR 1.69 (95% CI 1.26, 2.25)] were independently associated with food insufficiency. Food insufficiency interventions should address its accompanying psychosocial context.

Factors affecting linkage to HIV care and ART initiation following referral for ART by a mobile health clinic in South Africa: evidence from a multimethod study

Linkage to care from mobile clinics is often poor and inadequately understood. This multimethod study assessed linkage to care and antiretroviral therapy (ART) uptake following ART-referral by a mobile clinic in Cape Town (2015/2016). Clinic record data (N = 86) indicated that 67% linked to care (i.e., attended a clinic) and 42% initiated ART within 3 months. Linkage to care was positively associated with HIV-status disclosure intentions (aOR: 2.99, 95% CI 1.13-7.91), and treatment readiness (aOR: 2.97, 95% CI 1.05-8.34); and negatively with good health (aOR: 0.35, 95% CI 0.13-0.99), weekly alcohol consumption (aOR: 0.35, 95% CI 0.12-0.98), and internalised stigma (aOR: 0.32, 95% CI 0.11-0.91). Following linkage, perceived stigma negatively affected ART-initiation. In-depth interviews (N = 41) elucidated fears about ART side-effects, HIV-status denial, and food insecurity as barriers to ART initiation; while awareness of positive ART-effects, follow-up telephone counselling, familial responsibilities, and maintaining health to avoid involuntary disclosure were motivating factors. Results indicate that an array of interventions are required to encourage rapid ART-initiation following mobile clinic HIV-testing services.

Factors Associated with Outcomes of Pre-ART HIV Care

The World Health Organization recommended removing all CD4 requirements for initiation of antiretroviral therapy (ART) in resource-limited settings. We examined the pre-ART period to identify and assess factors associated with outcomes of pre-ART care. Four modes of transition out of pre-ART care were considered. Beta estimates from the competing risks Cox models were used to investigate whether the effects of covariates differed by mode of transition. Median CD4 counts at entry showed no meaningful change over time. Advanced disease progression and presence of opportunistic infections were significant predictors of pre-ART mortality. Men were more likely to die before initiating ART, transfer to another facility, or be lost to follow-up than were women. Removing CD4 thresholds is not likely to substantially reduce program mortality prior to ART initiation unless and until patients enroll earlier in disease progression. Care programs should focus on diagnosis and treatment of opportunistic infections to reduce pre-ART mortality.

Late ART Initiation among adult HIV patients at university of Gondar Hospital, NorthWest Ethiopia

Introduction

Late initiation of anti-retroviral therapy (ART) is associated with low immunologic response, increase morbidity, mortality and hospitalization. Therefore, this study aimed to assess the prevalence and factors associated with late ART initiation among adult HIV patients in NorthWest Ethiopia.

Methods

Retrospective cross-sectional study was conducted among 412 HIV patients who started ART between January/2009 and December/2014. Simple random sampling technique was used to select patient records. Data were collected by using pretested and structured extraction tool. Binary logistic regression model was fitted to identify factors associated with late ART initiation.

Result

A total of 410 participants were included for analysis after excluding 2 participants with incomplete data. The prevalence of late ART initiation was 67.3%. Age between 35–44 years(AOR=3.85; 95%CI:1.68–8.82), duration between testing and enrollment to care<1year (AOR=2.19;95%CI:1.30–3.69), secondary education (AOR=2.59; 95%CI 1.36–4.94), teritary education(AOR=3.28; 95%CI 1.25–8.64), being unmarried(AOR=1.88; 95%CI 1.13–3.03), bedridden and ambulatory patients (AOR=4.68 95%CI:1.49–14.68), other medication use before ART initiation(AOR=2.18; 95%CI 1.07–4.44), starting ART between 2009–2010 (AOR=5.94; 95%CI 2.74–12.87) and 2011–2012(AOR=2.80; 95%CI 1.31–5.96) were significantly associated with late ART initation at p-value <0.05.

Conclusion

The prevalence of late ART initiation was high. Strengthening the mechanisms of early HIV testing and linkage to care are recommended to initiate treatment earlier.

Advanced HIV: diagnosis, treatment, and prevention

Substantial progress has been made this century in bringing millions of people living with HIV into care, but progress for early HIV diagnosis has stalled. Individuals first diagnosed with advanced HIV have higher rates of mortality than those diagnosed at an earlier stage even after starting antiretroviral therapy (ART), resulting in substantial costs to health systems. Diagnosis of these individuals is hindered because many patients are asymptomatic, despite being severely immunosuppressed. Baseline CD4 counts and screening for opportunistic infections, such as tuberculosis and cryptococcus, is crucial because of the high mortality associated with these co-infections. Individuals with advanced HIV should have rapid ART initiation (except when found to have symptoms, signs, or a diagnosis of cryptococcal meningitis) and those in treatment failure should switch treatment. Overcoming barriers to testing and adherence through the development of differentiated care models and providing psychosocial support will be key in reaching populations at high risk of presenting with advanced HIV.

Gender Differences and Psychosocial Factors Associated with Problem Drinking Among Adults Enrolling in HIV Care in Tanzania

Problem drinking is commonly reported among people living with HIV (PLWH), associated with suboptimal HIV care outcomes and differs by gender. Psychosocial factors associated with problem drinking among PLWH remain poorly understood, including whether they differ by gender. This analysis examines the relationship between psychosocial factors and problem drinking separately by gender among PLWH in Tanzania. Cross-sectional data were collected from 812 men and non-pregnant women living with HIV aged 18 or older enrolling in HIV care at four health facilities in Tanzania. Problem drinking was assessed with the CAGE Questionnaire and defined as responding yes to two or more items. Sex-stratified multivariable logistic regression modeled the association of social support, HIV-related stigma, and physical or sexual violence on problem drinking, controlling for age, relationship status, employment, having been away from home for more than  one month, and timing of first HIV-positive diagnosis. Thirteen percent of the sample reported problem drinking, with problem drinking significantly more commonly reported among men than non-pregnant women (17.6% vs. 9.5%). Among men and non-pregnant women, in multivariable analyses, enacted and internalized HIV-related stigma were significantly positively associated with problem drinking. Screening and treatment of problem drinking should be integrated into HIV care. Evidence-based substance abuse interventions should be adapted to address HIV-related stigma. Future research should longitudinally investigate the interrelationships between stigma, violence, and problem drinking among PLWH.

Late Onset of Antiretroviral Therapy in Adults Living with HIV in an Urban Area in Brazil: Prevalence and Risk Factors

Introduction

Highly active antiretroviral therapy has been available since 1996. Early initiation of antiretroviral therapy (ART) leads to improved therapeutic response and reduced HIV transmission. However, a significant number of people living with HIV (PLHIV) still start treatment late.

Objective

This study aimed to analyze characteristics and factors associated with late initiation of ART among HIV-infected treatment-naïve patients.

Methods

This cross-sectional study included PLHIV older than 17 years who initiated ART at two public health facilities from 2009 to 2012, in a city located in Midwestern Brazil. Pregnant women were excluded. Data were collected from medical records, antiviral dispensing forms, and the Logistics Control of Medications System (SICLOM) of the Brazilian Ministry of Health. Late initiation of ART was defined as CD4+ cell count < 200 cells/mm³ or presence of AIDS-defining illness. Uni- and multivariate analysis were performed to evaluate associated factors for late ARV using SPSS®, version 21. The significance level was set at p<0.05.

Results

1,141 individuals were included, with a median age of 41 years, and 69.1% were male. The prevalence of late initiation of ART was 55.8% (95%CI: 52.9-58.7). The more common opportunistic infections at ART initiation were pneumocystosis, cerebral toxoplasmosis, tuberculosis, and histoplasmosis. Overall, 38.8% of patients had HIV viral load equal to or greater than 100,000 copies/mL. Late onset of ART was associated with higher mortality. After logistic regression, factors shown to be associated with late initiation of ARV were low education level, sexual orientation, high baseline viral load, place of residence outside metropolitan area, and concomitant infection with hepatitis B virus.

Conclusion

These results revealed the need to increase early treatment of HIV infection, focusing especially on groups of people who are more socially vulnerable or have lower self-perceived risk.

Research priorities to inform "Treat All" policy implementation for people living with HIV in sub-Saharan Africa: a consensus statement from the International epidemiology Databases to Evaluate AIDS (IeDEA)

INTRODUCTION

"Treat All" - the treatment of all people with HIV, irrespective of disease stage or CD4 cell count - represents a paradigm shift in HIV care that has the potential to end AIDS as a public health threat. With accelerating implementation of Treat All in sub-Saharan Africa (SSA), there is a need for a focused agenda and research to identify and inform strategies for promoting timely uptake of HIV treatment, retention in care, and sustained viral suppression and addressing bottlenecks impeding implementation.

METHODS

The Delphi approach was used to develop consensus around research priorities for Treat All implementation in SSA. Through an iterative process (June 2017 to March 2018), a set of research priorities was collectively formulated and refined by a technical working group and shared for review, deliberation and prioritization by more than 200 researchers, implementation experts, policy/decision-makers, and HIV community representatives in East, Central, Southern and West Africa.

RESULTS AND DISCUSSION

The process resulted in a list of nine research priorities for generating evidence to guide Treat All policies, implementation strategies and monitoring efforts. These priorities highlight the need for increased focus on adolescents, men, and those with mental health and substance use disorders - groups that remain underserved in SSA and for whom more effective testing, linkage and care strategies need to be identified. The priorities also reflect consensus on the need to: (1) generate accurate national and sub-national estimates of the size of key populations and describe those who remain underserved along the HIV-care continuum; (2) characterize the timeliness of HIV care and short- and long-term HIV care continuum outcomes, as well as factors influencing timely achievement of these outcomes; (3) estimate the incidence and prevalence of HIV-drug resistance and regimen switching; and (4) identify cost-effective and affordable service delivery models and strategies to optimize uptake and minimize gaps, disparities, and losses along the HIV-care continuum, particularly among underserved populations.

CONCLUSIONS

Reflecting consensus among a broad group of experts, researchers, policy- and decision-makers, PLWH, and other stakeholders, the resulting research priorities highlight important evidence gaps that are relevant for ministries of health, funders, normative bodies and research networks.

Evolution of Tuberculosis/Human Immunodeficiency Virus Services among Different Integrated Models in Myanmar: A Health Services Review

Myanmar is one of the highly affected countries by tuberculosis (TB) and human immunodeficiency virus (HIV) co-infection. We aimed to review the coverage of TB/HIV integrated services as well as to document the performance of this integrated services. A retrospective program review was conducted using the aggregated data of the National TB Programme (NTP) from 2005 to 2016. In Myanmar, TB/HIV services were initiated in seven townships in 2005. Townships were slowly expanded until 2013. After that, the momentum was increased by increasing the government budget allocation for NTP. In 2016, the whole country was eventually covered by TB/HIV services in different types of integration. Antiretroviral therapy (ART) coverage among HIV-positive TB patients remained low and it was the only significant difference among the three types of integration. Barriers of low ART coverage need to be investigated to reduce the burden of TB/HIV.

HIV-Related Stigma, Social Support, and Psychological Distress Among Individuals Initiating ART in Ethiopia

Recent World Health Organization HIV treatment guideline expansion may facilitate timely antiretroviral therapy (ART) initiation. However, large-scale success of universal treatment strategies requires a more comprehensive understanding of known barriers to early ART initiation. This work aims to advance a more comprehensive understanding of interrelationships among three known barriers to ART initiation: psychological distress, HIV-related stigma, and low social support. We analyzed cross-sectional interview data on 1175 adults initiating ART at six HIV treatment clinics in Ethiopia. Experience of each form of HIV-related stigma assessed (e.g., anticipatory, internalized, and enacted) was associated with increased odds of psychological distress. However, among those who reported enacted HIV-related stigma, there was no significant association between social support and psychological distress. Interventions to improve mental health among people living with HIV should consider incorporating components to address stigma, focusing on strategies to prevent or reduce the internalization of stigma, given the magnitude of the relationship between high internalized stigma and psychological distress. Interventions to increase social support may be insufficient to improve the mental health of people living with HIV who experienced enacted HIV-related stigma. Future research should examine alternative strategies to manage the mental health consequences of enacted HIV-related stigma, including coping skills training.

Immunological failure in HIV-infected adults from 2003 to 2015 in Southwest Ethiopia: a retrospective cohort study

OBJECTIVE

To assess the prevalence, trend and associated factors for immunological failure (IF), and the magnitude of antiretroviral therapy (ART) shift among adults infected with HIV in Southwest Ethiopia.

SETTING

A retrospective cohort study was undertaken using the data from ART clinic at Jimma University Teaching Hospital from 21 June 2003 to 15 March 2015.

PARTICIPANTS

Retrospective analysis of 4900 HIV-infected adult patient records dating from June 2003 to March 2015 was conducted.

PRIMARY OUTCOME MEASURE

The primary outcome was IF defined when cluster for differentiation 4 (CD4) count falls to the baseline (or below) or persistent CD4 levels below 100 cells/mm³ after 6 months of ART treatment. The analyses included descriptive and inferential statistics.

RESULTS

546 (19.5%) adults had developed clinical failure (CF), 775 (19.7%) adults had developed IF and 1231 (25.1%) had developed either CF or IF or both. The prevalence of IF was consistently high throughout the decade. Age 25 to ≤50 years adjusted OR (AOR 1.5, 9% CI 1.2 to 2.4), being female (AOR 1.8, 95% CI 1.3 to 1.9), late presenter for HIV care (AOR 2.2, 95% CI 1.6 to 2.7) and having baseline CD4 count below 200 cells/mm³ (AOR 5.5, 95% CI 4.1 to 7.4), and having no history of HIV testing before diagnosis (AOR 0.7, 95% CI 0.5 to 0.9) were the predictors for IF. Only 29 (0.9%) adults infected with HIV were shifted to second-line ART regimen.

CONCLUSIONS

The magnitude of CF or IF or both was found significant and consistently high throughout the calendar year although ART shift was found minimal. HIV-infected adult patients with IF were early age adults, females, late presenters for HIV care, and those who had low baseline CD4 counts and history of HIV testing before diagnosis.

Brief Report: Stigma and HIV Care Continuum Outcomes Among Ethiopian Adults Initiating ART

BACKGROUND

Stigma harms the mental health of HIV-positive individuals and reduces adherence to antiretroviral therapy (ART), but less is known about stigma and other outcomes across the HIV care continuum.

METHODS

Among 1180 Ethiopian adults initiating ART at 6 urban HIV clinics, we examined the relationship of internalized, anticipated, and enacted stigma to HIV care-related outcomes ascertained by interview (repeat HIV-positive testing, provider vs. self-referred testing, missed clinic visit before ART initiation, eagerness to begin ART), and by abstraction of routinely collected clinical data (late ART initiation, 3-month gap in care following ART initiation). Logistic regression was used to assess the association of each type of stigma with each outcome, adjusting for potential confounders.

RESULTS

Scoring higher on each stigma domain was associated with 50%-90% higher odds of repeat HIV-positive testing. High internalized stigma was associated with higher odds of provider vs. self-referred test [adjusted odds ratio (aOR)high vs. low: 1.7; 95% confidence interval (CI): 1.3 to 2.2]. Higher anticipated stigma was associated with lower eagerness to begin ART (aORhigh vs. low: 0.55; 0.35-0.87; aORmedium vs. low: 0.45; 95% CI: 0.30 to 0.69). Any enacted stigma was associated with higher odds of a missed visit (aORany vs. none 1.8; 1.2-2.8). Stigma was not associated with late ART-initiation or with a subsequent gap in care.

DISCUSSION AND CONCLUSIONS

These findings provide further evidence of the importance of measuring and addressing stigma across the entire care continuum. Future work should test hypotheses about specific stigma domains and outcomes in prospective intervention or observational studies.

Socio-economic status and time trends associated with early ART initiation following primary HIV infection in Montreal, Canada: 1996 to 2015

INTRODUCTION

Guidelines regarding antiretroviral therapy (ART) initiation in HIV infection have varied over time, with the 2015 World Health Organization recommendation suggesting ART initiation at the time of diagnosis regardless of CD4 T-cell counts. Herein, we investigated the influence of socio-demographic and clinical factors in addition to time trends on early ART initiation among participants of the Montreal Primary HIV Infection Study.

METHODS

The Montreal Primary HIV Infection Study is a prospective cohort established in three community medical centres (CMCs) and two university medical centres (UMCs). Recently diagnosed HIV-infected adults were categorized as receiving early (vs. delayed) ART if ART was initiated within 180 days of the baseline visit. Associations between early ART initiation and socio-demographic, socio-economic and behavioural information were examined. Independent associations of factors linked with early ART initiation were determined using multivariable binary logistic regression analysis.

RESULTS

A total of 348 participants had a documented date of HIV acquisition of <180 days. The median interquartile range (IQR) age of participants was 35 (28; 42) years and the majority were male (96%), having paid employment (63%), men who have sex with men (MSM) (78%) and one to four sexual partners in the last three months (70%). Participants presented with a median IQR HIV plasma viral load of 4.6 (3.7; 5.3) log10 copies/ml, CD4 count of 510 (387; 660) cells/μl and were recruited in CMCs (52%) or UMCs (48%). Early ART initiation was observed in 47% of the participants and the trend followed a V-shaped curve with peaks in 1996 to 1997 (89%) and 2013 to 2015 (88%) with a dip in 2007 to 2009 (22%). Multivariable analyses showed that having a paid employment adjusted odds ratio (aOR: 2.43; 95% CI: 1.19, 4.95), lower CD4 count (aOR per 50 cell increase: 0.93; 95% CI: 0.87, 0.99) and care at UMCs (aOR: 2.03; 95% CI: 1.06 to 3.90) were independently associated with early ART initiation.

CONCLUSIONS

Early ART initiation during primary HIV infection was associated with diminished biological prognostic factors and calendar time mirroring evolution of treatment guidelines. In addition, socio-economic factors such as having a paid employment, contribute to early ART initiation in the context of universal access to care in Canada.

Household decision-making power and the mental health and well-being of women initiating antiretroviral treatment in Oromia, Ethiopia

Low decision-making power (DMP) has been associated with HIV seropositivity among women in sub-Saharan Africa. As treatment accessibility and life expectancy for HIV-positive individuals increase, greater attention to the mental health and well-being of HIV-positive women is needed. This study examined whether low DMP was associated with psychological distress, social support or health-related quality of life (HRQoL) among women initiating ART. The sample included 722 women aged 18 or older initiating ART during 2012-2013 at six HIV clinics in Oromia, Ethiopia. DMP was assessed with five questions about household resource control and decision-making. Psychological distress was assessed with the Kessler Psychological Distress Scale (K10). HRQoL was assessed with the overall subscale of the HIV/AIDS-Targeted Quality of Life instrument. Multivariable logistic regression analyses controlled for age, education, and location (urban/rural). Most respondents (63%) reported high DMP, followed by medium (27%) and low (10%) DMP. More than half (57%) reported psychological distress. Compared to medium DMP, low DMP among married or cohabitating women was associated with greater odds of low social support (aOR: 1.9 [1.3, 2.9]; high DMP among women not in a relationship was associated with greater odds of low social support (aOR: 4.4 [2.4, 8.1]) and psychological distress (aOR: 1.7 [1.1, 2.6]). Interventions to reduce psychological distress among women initiating ART should consider the familial context, as high DMP among women not in a relationship was associated with psychological distress. High DMP may indicate weak social ties and fewer material resources, particularly among women not in a relationship.

"Testing, Testing": Multiple HIV-Positive Tests among Patients Initiating Antiretroviral Therapy in Ethiopia

Repeat HIV testing after receiving a positive result has never been studied systematically and may give insight into reasons for delayed linkage to care. Among 831 adults in 6 secondary facilities in Oromia, Ethiopia, who completed an interviewer-administered structured questionnaire within 2 weeks of initiating antiretroviral therapy in 2012 to 2013, 110 (13.2%) reported having retested after an HIV-positive result. The odds of repeat (versus single) HIV-positive testing were higher among those who had doubted their HIV status (adjusted odds ratio [AOR]_ref=nodoubt = 6.5; 95% confidence interval [CI]: 3.7-11.4) and those who initially tested at another facility, whether another secondary facility (AOR _{ref=studyfacility} = 22.7; 95% CI: 11.0-46.9) or a lower-level facility (AOR_{ref=studyfacility} = 19.1; 95% CI: 10.5-34.5). The odds of repeat (versus single) HIV-positive testing were lower among those who initially tested because of symptoms (AOR_{ref=not a reason} = 0.40; 95% CI: 0.24-0.66). Median time between initial diagnosis and enrollment in care was 12.3 versus 1.0 month for repeat and single HIV-positive testers, respectively ( P < .001). Repeat HIV-positive testing-not a rare occurrence-appears to stem from doubt, seeking care at a facility other than where diagnosed, and testing for a reason other than having symptoms. Because repeat HIV-positive testing is associated with delay in linkage to care, providers should be aware of this potential when counseling those who test HIV positive.

Understanding the relationship between couple dynamics and engagement with HIV care services: insights from a qualitative study in Eastern and Southern Africa

OBJECTIVE

To explore the interplay between couple dynamics and the engagement of people living with HIV (PLHIV) with HIV care and treatment services in three health and demographic surveillance sites in Tanzania, Malawi and South Africa.

METHODS

A qualitative study was conducted involving 107 in-depth interviews with PLHIV with a range of HIV care and treatment histories, including current users of HIV clinics, and people not enrolled in HIV care. Interviews explored experiences of living with HIV and how and why they chose to engage or not with HIV services. Thematic analysis was conducted with the aid of NVivo 10.

RESULTS

We found an interplay between couple dynamics and HIV care and treatment-seeking behaviour in Tanzania, Malawi and South Africa. Being in a relationship impacted on the level and type of engagement with HIV services in multiple ways. In some instances, couples living with HIV supported each other which improved their engagement with care and strengthened their relationships. The desire to fulfil societal expectations and attract a new partner, or have a baby with a new partner, or to receive emotional or financial support, strengthened on-going engagement with HIV care and treatment. However, fear of blame, abandonment or abuse resulted in unwillingness to disclose and often led to disputes or discord between couples. There was little evidence of intracouple understanding of each other's lived experiences with HIV, and we found that couples rarely interacted with the formal health system together.

CONCLUSIONS

Couple dynamics influenced engagement with HIV testing, care and treatment for both partners through a myriad of pathways. Couple-friendly approaches to HIV care and treatment are needed that move beyond individualised care and which recognise partner roles in HIV care engagement.

Psychological distress, health and treatment-related factors among individuals initiating ART in Oromia, Ethiopia

HIV diagnosis may be a source of psychological distress. Late initiation of antiretroviral therapy (ART) and treatment-related beliefs may intensify psychological distress among those recently diagnosed. This analysis describes the prevalence of psychological distress among people living with HIV (PLWH) and examines the association of recent HIV diagnosis, late ART initiation and treatment-related beliefs with psychological distress. The sample includes 1175 PLWH aged 18 or older initiating ART at six HIV clinics in Ethiopia. Psychological distress was assessed with Kessler Psychological Distress Scale. Scores ≥ 29 were categorized as severe psychological distress. Individuals who received their first HIV diagnosis in the past 90 days were categorized as recently diagnosed. Multivariable logistic regression modeled the association of recent diagnosis, late ART initiation and treatment-related beliefs on severe psychological distress, controlling for age, sex, education, area of residence, relationship status, and health facility. Among respondents, 29.5% reported severe psychological distress, 46.6% were recently diagnosed and 31.0% initiated ART late. In multivariable models, relative to those who did not initiate ART late and had longer time since diagnosis, odds of severe psychological distress was significantly greater among those with recent diagnosis and late ART initiation (adjusted OR [aOR]: 1.9 [95% CI 1.4, 2.8]). Treatment-related beliefs were not associated with severe psychological distress in multivariable models. Severe psychological distress was highly prevalent, particularly among those who were recently diagnosed and initiated ART late. Greater understanding of the relationship between psychological distress, recent diagnosis, and late ART initiation can inform interventions to reduce psychological distress among this population. Mental health screening and interventions should be incorporated into routine HIV clinical care from diagnosis through treatment.

A Framework for Health Communication Across the HIV Treatment Continuum

Supplemental Digital Content is Available in the Text.

Background:

As test and treat rolls out, effective interventions are needed to address the determinants of outcomes across the HIV treatment continuum and ensure that people infected with HIV are promptly tested, initiate treatment early, adhere to treatment, and are virally suppressed. Communication approaches offer viable options for promoting relevant behaviors across the continuum.

Conceptual Framework:

This article introduces a conceptual framework, which can guide the development of effective health communication interventions and activities that aim to impact behaviors across the HIV treatment continuum in low- and medium-income countries. The framework includes HIV testing and counseling, linkage to care, retention in pre-antiretroviral therapy and antiretroviral therapy initiation in one single-stage linkage to care and treatment, and adherence for viral suppression. The determinants of behaviors vary across the continuum and include both facilitators and barriers with communication interventions designed to focus on specific determinants presented in the model. At each stage, relevant determinants occur at the various levels of the social–ecological model: intrapersonal, interpersonal, health services, community, and policy. Effective health communication interventions have mainly relied on mHealth, interpersonal communication through service providers and peers, community support groups, and treatment supporters.

Discussion:

The conceptual framework and evidence presented highlight areas across the continuum where health communication can significantly impact treatment outcomes to reach the 90-90-90 goals by strategically addressing key behavioral determinants. As test and treat rolls out, multifaceted health communication approaches will be critical.

Depression and ART Initiation Among HIV Serodiscordant Couples in Kenya and Uganda

Depression is a known barrier for antiretroviral therapy (ART) adherence, but less is understood about its effects on ART initiation. We followed 1013 HIV-infected individuals participating in the Partners Demonstration Project, an open-label study of integrated pre-exposure prophylaxis (PrEP) and ART delivery for HIV serodiscordant couples in Kenya and Uganda. Associations between depression, measured annually with the Hopkins Symptoms Checklist-Depression (HSCL-D), and ART initiation were assessed with Cox proportional hazards regression. At enrollment, 162 participants (16.0%) reported symptoms consistent with probable depression, defined by a HSCL-D mean score >1.75, and this proportion decreased during study follow-up (6.7 and 3.6% at 12- and 24-months, respectively; p value < 0.001). Greater depressive symptom severity was associated with a greater likelihood of ART initiation overall (adjusted hazard ratio [aHR] 1.32, 95% CI 1.01-1.73) and among participants with CD4 count ≤ 350 cells/µl (aHR 1.30, 95% CI 1.01-1.67). Depression decreased 6 months after ART initiation (adjusted odds ratio [aOR] 0.34, 95% CI 0.23-0.51). Among East African HIV-infected persons in HIV serodiscordant couples, depression was not a barrier to ART initiation. ART initiation was associated with improved depressive symptoms in this setting.

Prevalence, trend and risk factors for antiretroviral therapy discontinuation among HIV-infected adults in Ethiopia in 2003-2015

BACKGROUND

It is well acknowledged that antiretroviral therapy (ART) discontinuation hampers the progress towards achieving the UNAIDS treatment targets that aim to treat 90% of HIV diagnosed patients and achieve viral suppression for 90% of those on treatment. Nevertheless, the magnitude, trend and risk factors for ART discontinuation have not been explored extensively. We carried out a retrospective data analysis to assess prevalence, trend and risk factors for ART discontinuation among adults in Southwest Ethiopia.

METHODS

12 years retrospective cohort analysis was performed with 4900 HIV-infected adult patients between 21 June 2003 and 15 March 2015 registered at the ART clinic at Jimma University Teaching Hospital. ART discontinuation could be loss to follow-up, defaulting and/or stopping medication while remaining in care. Because data for 2003 and 2015 were incomplete, the 10 years data were used to describe trends for ART discontinuation using a line graph. We used binary logistic regression to identify factors that were correlated with ART discontinuation. To handle missing data, we applied multiple imputations assuming missing at random pattern.

RESULTS

In total, 4900 adult patients enrolled on ART, of whom 1090 (22.3%) had discontinued, 954 (19.5%) had transferred out, 300 (6.1%) had died, 2517 (51.4%) were alive and on ART, and the remaining 39 (0.8%) had unknown outcome status. The trend of ART discontinuation showed an upward direction in the recent times and reached a peak, accounting for a magnitude of 10%, in 2004 and 2005. Being a female (AOR = 2.1, 95%CI: 1.7-2.8), having an immunological failure (AOR = 2.3, 1.9-8.2), having tuberculosis/HIV co-infection (AOR = 1.5, 1.1-2.1) and no previous history of HIV testing (AOR = 1.8, 1.4-2.9) were the risk factors for ART discontinuation.

CONCLUSIONS

One out of five adults had discontinued from ART, and the trend of ART discontinuation increased recently. Discontinued adults were more likely to be females, tuberculosis/HIV co-infected, with immunological failure and no history of HIV testing. Therefore, it is vital to implement effective programs such as community ART distribution and linkage-case-management to enhance ART linkage and retention.

Conceptualizing Care Continua: Lessons from HIV, Hepatitis C Virus, Tuberculosis and Implications for the Development of Improved Care and Prevention Continua

Background

To examine the application of continuum models to tuberculosis, HIV, and other conditions; to theorize the concept of continua; and to learn lessons that could inform the development of improved care and prevention continua as public health metrics.

Methods

An analytic review of literature drawn from several fields of health care.

Results

The continuum construct is now part of public health evaluation systems for HIV, and is increasingly used in public health and the medical literature. Issues with the comparability and optimal design of care continuum models have been raised, and their methodologic and theoretic underpinnings and scope of focus have been under-addressed. Review of relevant publications suggests that a key limitation of current models is their lack of measures reflecting incidence and mortality. Issues relating to continua data being longitudinal or cross-sectional, definition of numerators and denominators for each step, data sources, measures of timeliness of step completion, theoretic models to facilitate inferences of causes of care continuum gaps, how measures of prevention efforts, reinfection/relapses, and interactions of continua for co-occurring comorbidities should be reflected, and how analyses of differences in retention over time, across geographic regions, and in response to interventions should be conducted are critical to the development of sound care and prevention continuum models.

Conclusion

Lessons learned from the application of continuum models to HIV and other conditions suggest that the application of well-formulated constructs of care and prevention continua, that depict, in well defined, standardized steps, incidence and mortality, along with degrees of and time to screening, engagement in care and prevention, treatment and treatment outcomes, including relapse or reinfection, may be vital tools in evaluating intervention and program outcomes, and in improving population health and population health metrics for a wide range conditions.
