Low HIV viral suppression rates following the intensive adherence counseling (IAC) program for children and adolescents with viral failure in public health facilities in Uganda

Epidemiological features of HIV/AIDS in the Middle East and North Africa from 1990 to 2017

The growing trend of HIV/AIDS is a major concern in the Middle East and North Africa (MENA) regions, as its incidence in the region has increased by 31% in the last decade. The study population in the countries of the MENA region included 21 countries with a population of approximately 400 million. The Global Burden of Disease database was used to calculate the number of HIV/AIDS cases. Modeling for each country is based on the availability and quality of data. The highest incidence rates of HIV/AIDS were in Sudan, United Arab Emirates (UAE), Tunisia, and Iran, respectively, and the highest mortality rates were in Sudan, UAE, Oman, and Morocco, respectively. The incidence, prevalence and mortality rates, as well as the disability adjusted life years (DALYs) rate declined in 2017 compared to 1990. The highest percentage of changes in DALY rates was reported for Turkey, the United Arab Emirates (UAE), and Sudan, respectively, and the lowest for Qatar, Kuwait, and Bahrain. In general, unsafe sex had the highest impact on the DALY index in all countries in the region except Iran and Bahrain. Policymakers should therefore be encouraged to develop harm reduction programs for people living with HIV, and invest globally in reducing HIV prevalence rates in commercial sex workers, people who inject drugs, and men who have sex with men in the region, as well as eliminating mother-to-child HIV transmission.

Factors associated with virological non-suppression among HIV-positive children receiving antiretroviral therapy at the Joint Clinical Research Centre in Lubowa, Kampala Uganda

BACKGROUND

While the proportion of HIV-positive children (under 15 years) enrolled on antiretroviral therapy (ART) has increased in recent years, up to 60% of children started on ART do not achieve virological suppression. We set out to determine the factors associated with virological non-suppression among children living with HIV receiving ART at a peri-urban HIV care clinic in Kampala, Uganda.

METHOD

This was a retrospective cohort study conducted at the pediatric HIV/AIDS clinic at the Joint Clinical Research Centre (JCRC) in Kampala, Uganda. Three hundred (300) HIV-positive children (0-14 years) were randomly selected from existing medical records and data on children's socio-demographic and clinical characteristics (age at ART initiation, WHO clinical staging, and ART-induced side effects) were abstracted using a data abstraction form. Virological non-suppression was defined as a viral load ≥1000 copies/Ml of blood after six months of ART initiation. Incident rate ratios (IRRs) were determined as a measure of association between virological non-suppression and child/patient characteristics. The IRRs were obtained via a modified Poisson regression with corresponding 95% confidence intervals (95%CI). All analyses were done using statistical package, Stata version 15.

RESULTS

The overall non-suppression rate among HIV-positive children on ART was 23%. Being at WHO clinical stage 4 at ART initiation [adj. IRR 2.74; 95%CI: 1.63, 4.61] and ART-induced side effects [adj. IRR 1.77; 95%CI: 1.06, 2.97] were significantly associated with non-suppression. Older age at ART initiation (age 5-9 years: [adj. IRR 0.42; 95%CI: 0.28, 0.65]; age 10-14 years: [adj. IRR 0.34; 95%CI: 0.18, 0.64] was less likely to be associated with virological non-suppression.

CONCLUSION

Nearly a quarter of HIV-positive children on ART had a non-suppressed viral load after six months of treatment. Being at WHO clinical stage 4 at ART initiation and ART-induced side effects were significantly associated with virological non-suppression while older age at ART initiation was protective. Our findings suggest a need for age-specific interventions, particularly those targeting children below five years of age, to improve virological suppression among HIV-positive children receiving ART in this setting.

Predictors of Virological Failure after Adherence-Enhancement Counseling among First-Line Adults Living with HIV/AIDS in Kombolcha Town, Northeast Ethiopia

BACKGROUND

HIV virological failure is a common challenging problem, even after adherence-enhancement counseling. However, there have been few studies on the determinants of virological failure after adherence-enhancement counseling among adult patients on antiretroviral therapy in Ethiopia in general, and there is variation across clients and settings for unknown reasons. Therefore, this study aimed to identify predictors of virological failure after adherence-enhancement counseling among adults living with HIV/AIDS.

METHODS

A case-control study was conducted in the town of Kombolcha from January 1, 2019 to March 30, 2019 using simple random sampling for 338 participants. Data were collected through face-to-face interviews for social and personal characteristics and document review for clinical profiles. Descriptive statistics were used for frequency, proportions, and summary measures. Binary logistic regression analysis was carried out to identify the predictors of virological failure after adherence-enhancement counseling among adults. For multivariate logistic regression,P<0.05 was considered statistically significant. AORs are presented with 95% CIs.

RESULTS

The odds of virological failure after adherence-enhancement counseling were higher following poor antiretroviral medication adherence (AOR 7.3, 95% CI 2.57-20.79) and for patients who had had a first high viral load (≥10,000 copies/mL, (AOR 5, 95% CI 1.86-13.56) and a history of opportunistic infection (AOR 3.7, 95% CI 1.11-8.44) compared with their counterparts.

CONCLUSION

Poor antiretroviral medication adherence during adherence-enhancement counseling session, first viral load ≥10,000 copies/mL, and recent history of opportunistic infection were predictors of virological failure. Therefore, efforts should be strengthened to improve adherence to antiretroviral medication, which helps to boost immunity and suppress viral replication.

Optimizing viral load suppression in Kenyan children on antiretroviral therapy (Opt4Kids)

Background

As many as 40% of the 1 million children living with HIV (CLHIV) receiving antiretroviral treatment (ART) in resource limited settings have not achieved viral suppression (VS). Kenya has a large burden of pediatric HIV with nearly 140,000 CLHIV. Feasible, scalable, and cost-effective approaches to ensure VS in CLHIV are urgently needed. The goal of this study is to determine the feasibility and impact of point-of-care (POC) viral load (VL) and targeted drug resistance mutation (DRM) testing to improve VS in children on ART in Kenya.

Methods

We are conducting a randomized controlled study to evaluate the use of POC VL and targeted DRM testing among 704 children aged 1-14 years on ART at health facilities in western Kenya. Children are randomized 1:1 to intervention (higher frequency POC VL and targeted DRM testing) vs. control (standard-of-care) arms and followed for 12 months. Our primary outcome is VS (VL < 1000 copies/mL) 12 months after enrollment by study arm. Secondary outcomes include time to VS and the impact of targeted DRM testing on VS. In addition, key informant interviews with patients and providers will generate an understanding of how the POC VL intervention functions. Finally, we will model the cost-effectiveness of POC VL combined with targeted DRM testing.

Discussion

This study will provide critical information on the impact of POC VL and DRM testing on VS among CLHIV on ART in a resource-limited setting and directly address the need to find approaches that maximize VS among children on ART.

'There are no more secrets': acceptability of a family-centered model of care for HIV positive children in Eswatini

BACKGROUND

HIV-positive children have lagged adults on retention in HIV care and viral suppression. To address this gap, Eswatini's Ministry of Health started a pilot family-centered HIV care model (FCCM) targeting HIV-positive children under 20 years old and their families.

METHODS

We conducted semi-structured in-depth interviews with 25 caregivers and 17 healthcare workers (HCWs) to assess acceptability of FCCM in four pilot FCCM health facilities in Hhohho region of Eswatini. Thematic analysis with inductive and deductive codes was used to identify salient themes.

RESULTS

Caregivers and HCWs reported FCCM benefits including strengthening the family bond, encouragement for family members to disclose their HIV status and supporting each other in taking antiretroviral drugs. Caregivers reported that they spent fewer days in clinic, experienced shorter waiting times, and received better counseling services in FCCM compared to the standard-of-care services. FCCM implementation challenges included difficulty for families to attend clinic visits together (e.g., due to scheduling conflicts with weekend Teen Support Club meetings and weekday FCCM appointments). Both HCWs and caregivers mentioned difficulty in sharing sensitive health information in the presence of other family members. HCWs also had challenges with supporting caregivers to disclose HIV status to children and managing the larger group during clinic visits.

CONCLUSIONS

FCCM for HIV-positive children was acceptable to both caregivers and HCWs, and they supported scaling-up FCCM implementation nationally. However, special considerations should be made to address the challenges experienced by participants in attending clinic visits together as a family in order to achieve the full benefits of FCCM for HIV positive children.

Interventions to Improve Antiretroviral Therapy Adherence Among Adolescents and Youth in Low- and Middle-Income Countries: A Systematic Review 2015-2019

Adolescents and youth living with HIV have poorer antiretroviral treatment (ART) adherence and viral suppression outcomes than all other age groups. Effective interventions promoting adherence are urgently needed. We reviewed and synthesized recent literature on interventions to improve ART adherence among this vulnerable population. We focus on studies conducted in low- and middle-income countries (LMIC) where the adolescent and youth HIV burden is greatest. Articles published between September 2015 and January 2019 were identified through PubMed. Inclusion criteria were: [1] included participants ages 10-24 years; [2] assessed the efficacy of an intervention to improve ART adherence; [3] reported an ART adherence measurement or viral load; [4] conducted in a LMIC. Articles were reviewed for study population characteristics, intervention type, study design, outcomes measured, and intervention effect. Strength of each study's evidence was evaluated according to an adapted World Health Organization GRADE system. Articles meeting all inclusion criteria except being conducted in an LMIC were reviewed for results and potential transportability to a LMIC setting. Of 108 articles identified, 7 met criteria for inclusion. Three evaluated patient-level interventions and four evaluated health services interventions. Of the patient-level interventions, two were experimental designs and one was a retrospective cohort study. None of these interventions improved ART adherence or viral suppression. Of the four health services interventions, two targeted stable patients and reduced the amount of time spent in the clinic or grouped patients together for bi-monthly meetings, and two targeted patients newly diagnosed with HIV or not yet deemed clinically stable and augmented clinical care with home-based case-management. The two studies targeting stable patients used retrospective cohort designs and found that adolescents and youth were less likely to maintain viral suppression than children or adults. The two studies targeting patients not yet deemed clinically stable included one experimental and one retrospective cohort design and showed improved ART adherence and viral suppression outcomes. ART adherence and viral suppression outcomes remain a major challenge among adolescents and youth. Intensive home-based case management models of care hold promise for improving outcomes in this population and warrant further research.

Fostering successful and sustainable collaborations to advance implementation science: the adolescent HIV prevention and treatment implementation science alliance

INTRODUCTION

HIV continues to devastate the adolescent population in sub-Saharan Africa (SSA). The complex array of interpersonal, social, structural and system-level obstacles specific to adolescents have slowed progress in prevention and treatment of HIV in this population. The field of implementation science holds promise for addressing these challenges.

DISCUSSION

There is growing consensus that enhanced interactions between researchers and users of scientific evidence are important and necessary to tackle enduring barriers to implementation. In 2017, the Fogarty International Center launched the Adolescent HIV Prevention and Treatment Implementation Science Alliance (AHISA) to promote communication and catalyse collaboration among implementation scientists and implementers to enhance the cross-fertilization of insights as research advances and the implementation environment evolves. This network has identified key implementation science questions for adolescent HIV, assessed how members' research is addressing them, and is currently conducting a concept mapping exercise to more systematically identify implementation research priorities. In addition, AHSA pinpointed common challenges to addressing these questions and discussed their collective capacity to conduct implementation science using the shared learning approach of the network. Specifically, AHISA addresses challenges related to capacity building, developing mentorship, engaging stakeholders, and involving adolescents through support for training efforts and funding region-/country-specific networks that respond to local issues and increase implementation science capacity across SSA.

CONCLUSIONS

Innovative platforms, like AHISA, that foster collaborations between implementation science researchers, policymakers and community participants to prioritizes research needs and identify and address implementation challenges can speed the translation of effective HIV interventions to benefit adolescent health.

Magnitude of non-adherence to antiretroviral therapy and associated factors among adult people living with HIV/AIDS in Benishangul-Gumuz Regional State, Ethiopia

Introduction

Following global efforts to increase antiretroviral therapy (ART) access and coverage, Ethiopia has made significant achievement with a 6.3% annual decline in the HIV/AIDS incidence rate between 1990 and 2016. Such success depends not only on access to ART but also on attaining optimum treatment adherence. Emerging studies in Ethiopia has shown the increasing prevalence of poor adherence and lack of the desired viral suppression, but the extent and factors associated with non-adherence to ART are not well known, especially in the current study setup. In this study, we examined the magnitude and factors associated with treatment and non-adherence to ART among people living with HIV in Benishangul-Gumuz Regional State, northwest Ethiopia.

Methods

An institutional facility based cross-sectional descriptive study was carried out among adult people living with HIV/AIDS from mid-December 2016 to February 2017 with only 98.9% response rate. Sociodemographic factors (age, gender, marital status and residential area), economic factors (educational status, income, asset possession, employment status, dietary diversity, nutritional status and food security), and clinical characteristics (CD4 count, duration on ART and history of opportunistic infections) were explanatory variables. ART non-adherence was measured using a visual analogue scale (VAS). We used binary logistic regression and subsequent multivariate logistic regression analysis to determine the factors associated with ART non-adherence.

Result

Overall, 39.7% of the participants were found non-adherent to ART. Strong association was found between non-adherence to ART and young age below 25 years (AOR: 4.30, 95% CI [1.39-3.35]; p = 0.011), urban residential area (AOR: 2.78, CI [1.23-7.09], p = 0.043), lack of employment (AOR: 1.75, 95% CI [1.05-2.91], p = 0.032), food insecurity (AOR: 2.67, 95% CI [7.59-8.97]; p < 0.0001), malnutrition (AOR: 1.55, 95% CI [1.94-2.56]; p = 0.027) and opportunistic infections (AOR: 1.81, 95% CI [1.11-2.97]; p = 0.018).

Conclusion

The prevalence of non-adherence to ART in this study was high. Sociodemographic and economic factors such as young age of below 25 years, urban residential area, lack of employment, food insecurity, malnutrition and opportunistic infections were among the factors associated with non-adherence to ART.

Modeling Viral Suppression, Viral Rebound and State-Specific Duration of HIV Patients with CD4 Count Adjustment: Parametric Multistate Frailty Model Approach

INTRODUCTION

Combination antiretroviral therapy has become the standard care of human immunodeficiency virus (HIV)-infected patients and has further led to a dramatically decreased progression probability to acquired immune deficiency syndrome (AIDS) for patients under such a therapy. However, responses of the patients to this therapy have recorded heterogeneous complexity and high dynamism. In this paper, we simultaneously model long-term viral suppression, viral rebound, and state-specific duration of HIV-infected patients.

METHODS

Full-parametric and semi-parametric Markov multistate models were applied to assess the effects of covariates namely TB co-infection, educational status, marital status, age, quality of life (QoL) scores, white and red blood cell parameters, and liver enzyme abnormality on long-term viral suppression, viral rebound and state-specific duration for HIV-infected individuals before and after treatment. Furthermore, two models, one including and another excluding the effect of the frailty, were presented and compared in this study.

RESULTS

Results from the diagnostic plots, Akaike information criterion (AIC) and likelihood ratio test showed that the Weibull multistate frailty model fitted significantly better than the exponential and semi-parametric multistate models. Viral rebound was found to be significantly associated with many sex partners, higher eosinophils count, younger age, lower educational level, higher monocyte counts, having abnormal neutrophils count, and higher liver enzyme abnormality. Furthermore, viral suppression was also found to be significantly associated with higher QoL scores, and having a stable sex partner. The analysis result also showed that patients with a stable sex partner, higher educational levels, higher QoL scores, lower eosinophils count, lower monocyte counts, and higher RBC indices were more likely to spend more time in undetectable viral load state.

CONCLUSIONS

To achieve and maintain the UNAIDS 90% suppression targets, additional interventions are required to optimize antiretroviral therapy outcomes, specifically targeting those with poor clinical characteristics, lower education, younger age, and those with many sex partners. From a methodological perspective, the parametric multistate approach with frailty is a flexible approach for modeling time-varying variables, allowing for dealing with heterogeneity between the sequence of transitions, as well as allowing for a reasonable degree of flexibility with a few additional parameters, which then aids in gaining a better insight into how factors change over time.

Programme quality indicators of HIV drug resistance among adolescents in urban versus rural settings of the centre region of Cameroon

BACKGROUND

The high rate of mortality among HIV-vertically infected adolescents might be favoured by HIV drug resistance (HIVDR) emergence, which calls for timeous actions in this underserved population. We thus sought to evaluate program quality indicators (PQIs) of HIVDR among HIV-vertically infected adolescents on antiretroviral therapy (ART).

METHODS

A study was conducted in the Centre region of Cameroon among adolescents (10-19 years) receiving ART in two urban (The Mother-Child Centre of the Chantal BIYA Foundation, the National Social Welfare Hospital) and three rural (Mfou District Hospital, Mbalmayo District Hospital and Nkomo Medical Center) health facilities. Following an exhaustive sampling from ART registers, patient medical files and pharmacy records, data was abstracted for seven PQIs: on-time drug pick-up; retention in care; pharmacy stock outs; dispensing practices; viral load coverage; viral suppression and adequate switch to second-line. Performance in PQIs was interpreted following the WHO-recommended thresholds (desirable, fair and/or poor); with p < 0.05 considered significant.

RESULTS

Among 967 adolescents (888 urban versus 79 rural) registered in the study sites, validated data was available for 633 (554 in urban and 79 in rural). Performance in the urban vs. rural settings was respectively: on-time drug pick-up was significantly poorer in rural (79% vs. 46%, p = 0.00000006); retention in care was fair in urban (80% vs. 72%, p = 0.17); pharmacy stock outs was significantly higher in urban settings (92% vs. 50%, p = 0.004); dispensing practices was desirable (100% vs. 100%, p = 1.000); viral load coverage was desirable only in urban sites (84% vs. 37%, p < 0.0001); viral suppression was poor (33% vs. 53%, p = 0.08); adequate switch to second-line varied (38.1% vs. 100%, p = 0.384).

CONCLUSION

Among adolescents on ART in Cameroon, dispensing practices are appropriate, while adherence to ART program and viral load coverage are better in urban settings. However, in both urban and rural settings, pharmacy stock outs, poor viral suppression and inadequate switch to second-line among adolescents require corrective public-health actions to limit HIVDR and to improve transition towards adult care in countries sharing similar programmatic features.

Routine viral load monitoring and enhanced adherence counselling at a public ART centre in Mumbai, India

Background

Routine viral-load (VL) measurements along with enhanced adherence counselling (EAC) are recommended to achieve virological suppression among people living with HIV/AIDS (PLHA) on anti-retroviral therapy (ART). The Mumbai Districts AIDS Control Society along with Médecins Sans Frontières has provided routine VL measurements and EAC to PLHA on ART at King Edward Memorial (KEM) hospital, Mumbai since October-2016. This study aims to describe the initial VL results and impact of EAC on viral suppression and factors associated with initial viral non-suppression among patients with an initial detectable VL, in a cohort of patients tested between October-2016 and September-2018.

Methods

This is a descriptive study of PLHA on ART who received VL testing and EAC during October-2016 to September-2018. Log-binomial regression was used to identify factors associated with a high VL.

Results

Among 3849 PLHA who underwent VL testing, 1603(42%) were female and median age was 42 years (IQR:35–48). Majority were referred for routine testing (3432(89%)) and clinical/immunological failure (233(6%)). Overall, 3402(88%) PLHA had suppressed VL at initial testing. Among 3432 tested for routine monitoring, 3141(92%) had VL suppressed. Of 291 with VL>1000c/ml, 253(87%) received EAC and after repeat VL, 70(28%) had VL<1000c/ml. Among 233 referred for clinical/immunological failure, 122(52%) had VL>1000c/ml and 109 have been switched to second-line ART.

CD4 count<500 (aOR-5.0[95%CI 3.8–6.5]), on ART for<5 years (aOR-1.5[1.1–2.0]) and age<15 years (aOR-5.2[3.0–8.9]) were associated with an initial VL>1000c/ml. Factors associated with follow-up VL suppression included EAC (p<0.05) and being on second-line ART (p<0.05).

Conclusion

Results from a routine VL program in public sector in India were encouraging and in line with UNAIDS 90-90-90 targets. Routine VL monitoring along with EAC resulted in early switch to alternative optimised regimens while also preventing unnecessary switches. Along with the vital scale up of routine VL monitoring, implementation of enhanced adherence strategies for patients with detectable viral load should be ensured.

Viral Load Suppression after Enhanced Adherence Counseling and Its Predictors among High Viral Load HIV Seropositive People in North Wollo Zone Public Hospitals, Northeast Ethiopia, 2019: Retrospective Cohort Study

BACKGROUND

The World Health Organization currently encourages enhanced adherence counseling for human immunodeficiency virus (HIV) seropositive people with a high viral load count before a treatment switch to the second-line regimen, yet little is known about viral load suppression after the outcome of enhanced adherence counseling. Therefore, this study aimed to assess viral suppression after enhanced adherence counseling sessions and its predictors among high viral load HIV seropositive people.

METHODS

Institutional-based retrospective cohort study was conducted among 235 randomly selected HIV seropositive people who were on ART and had a high viral load (>1000 copies/ml) from June 2016 to January 2019. The proportion of viral load suppression after enhanced adherence counseling was determined. Time to completion of counseling sessions and time to second viral load tests were estimated by the Kaplan-Meier curve. Log binomial regression was used to identify predictors of viral re-suppression after enhanced adherence counseling sessions.

RESULT

The overall viral load suppression after enhanced adherence counseling was 66.4% (60.0-72.4). The median time to start adherence counseling session after high viral load detected date was 8 weeks (IQR 4-8 weeks), and the median time to complete the counseling session was 13 weeks (IQR 8-25 weeks). The probability of viral load suppression was higher among females (ARR = 1.2, 95% CI: 1.02-1.19) and higher educational status (ARR = 1.7, 95% CI: 1.25-2.16). The probability of viral load suppression was lower among people who had 36-59 months duration on ART (ARR = 0.35, 95% CI: 0.130-0.9491) and people who had > 10,000 baseline viral load count (ARR = 0.44, 95% CI: 0.28-0.71).

CONCLUSION

This study showed that viral suppression after enhanced adherence counseling was near to the WHO target (70%) but highlights gaps in time to enrolment into counseling session, timely completion of counseling session, and repeat viral load testing after completing the session.

HIV viral resuppression following an elevated viral load: a systematic review and meta-analysis

INTRODUCTION

Guidelines for antiretroviral therapy recommend enhanced adherence counselling be provided to individuals with an initial elevated viral load before making a decision whether to switch antiretroviral regimen. We undertook this systematic review to estimate the proportion of patients with an initial elevated viral load who resuppress following enhanced adherence counselling.

METHODS

Two databases and two conference abstract sites were searched from January 2012 to October 2019 for studies reporting the number of patients with an elevated viral load whose viral load was undetectable when subsequently assessed. Data were pooled using random effects meta-analysis.

RESULTS

Fifty-eight studies reported outcomes of 45,720 viraemic patients, mostly from Africa (48 studies), and among patients on first-line antiretroviral therapy (43 studies). Almost half (46.1%, 95% CI 42.6% to 49.5%) of patients with an initial elevated viral load resuppressed following an enhanced adherence intervention. Of those on first-line ART with confirmed virological failure (6280 patients, 21 studies), only 53.4% (40.1% to 66.8%) were appropriately switched to a different regimen. Resuppression was higher among studies that provided details of adherence support. The proportion resuppressing was lower among children (31.2%, 21.1% to 41.3%) and adolescents (40.4%, 15.7% to 65.2%) compared to adults (50.4%, 42.6% to 58.3%). No important differences were observed by date of study publication, gender, viral failure threshold, publication status, time between viral loads or treatment regimen. Information on resistance testing among people with an elevated viral load was inconsistently reported.

CONCLUSIONS

The findings of this review suggest that in settings with limited resources, current guideline recommendations to provide enhanced adherence counselling can result in resuppression of a substantial number of these patients, avoiding unnecessary drug regimen changes. Appropriate action on viral load results is limited across a range of settings, highlighting the importance of viral load cascade analyses to identify gaps and focus quality improvement to ensure that action is taken on the results of viral load testing.

Viral suppression rate among children tested for HIV viral load at the Amhara Public Health Institute, Bahir Dar, Ethiopia

Background

Human immunodeficiency virus (HIV) infected children represent a very vulnerable population for anti-retroviral therapy (ART) drug resistance. As a global target, 90% of patients receiving ART should have HIV-RNA viral suppression. A threshold of > 1000 RNA copies/ml is used to define non-suppressed viral load. If it is confirmed in the laboratory, adherence should be addressed and should be followed by the switch to second-line ART. Therefore, the aim of this study was to assess the rate of viral load suppression among children tested at the Amhara Public Health Institute (APHI), Bahir Dar.

Methods

Institutional based cross-sectional study design was conducted from July 01, 2017 to June 30, 2018, in children under the age of 15 years. Socio-demographic, clinical and HIV1RNA viral load data were collected from the excel database. The data were analyzed in SPSS 20.0 statistical software.

Results

A total of 1567 children, age ranged from one to 14 years, were tested for HIV viral load. Of which, about 54% were males. Children were treated using nevirapine-based (76.7%), efavirenz-based (21.8%) and protease inhibitor-based (1.5%) anti-retroviral drugs. Non-suppressed HIV viral load was found in 28.3% of the participants. High viral load (> 1000 cp/ml) were found in 24% of the children below the age of five years. Children on nevirapine-based treatment had about two times more non-suppressed viral load (Adjusted odds ratio [AOR]: 1.90; 95%CI: 1.41–2.56; P < 0.001) compared to those who had efavirenz-based treatment. However, adherence (P: 0.204) was not associated with non-suppressed viral load.

Conclusions

There was a high rate of non-suppressed HIV viral load among children tested at APHI. Specifically, the odds of having a non-suppressed viral load was higher in NVP based treatment users. Hence, comprehensive management and follow up of children on ART, and testing for resistance as well as viral load could help to reduce the problem in advance.

Pursuing use of optimal formulations for paediatric HIV epidemic control - a look at the use of LPV/r oral pellets and oral granules

INTRODUCTION

Despite a significant reduction in mother-to-child transmission of HIV, an estimated 180,000 children were infected with HIV in 2017, and only 52% of children under 15 years of age living with HIV (CLHIV) are on life-saving antiretroviral therapy (ART). Without effective treatment, half of CLHIV die before the age of two years and only one in five survives to five years of age.

DISCUSSION

Over the past four years, the United States Food and Drug Administration tentatively approved new formulations of lopinavir/ritonavir (LPV/r) in the form of oral pellets and oral granules. However, the slow uptake of the aforementioned formulations in the low- and middle-income countries with the highest paediatric HIV burden is largely due to three challenges: limited manufacturing capacity; current unit cost of the pellets and granules; and slow uptake of these new formulations by policy makers and health care workers.

CONCLUSIONS

Solutions to overcome these barriers include ensuring availability of an adequate supply of LPV/r oral pellets and oral granules, considering all programmatic and clinical factors when selecting paediatric ART formulations, and leveraging current resources to decrease paediatric HIV morbidity and mortality.

Challenges faced by caregivers of virally non-suppressed children on the intensive adherence counselling program in Uganda: a qualitative study

Background

Of the estimated 130,000 children living with HIV in Uganda, 47% are receiving ART. Only 39.3% have suppressed HIV-1 viral load to levels below 50 copies per ml. Caregivers are key drivers of adherence to achieve viral suppression in children. We investigated the challenges and potential support required by caregivers of ART-treated children.

Methods

A qualitative study was conducted within the Infectious Diseases Institute paediatric ART program in Kampala and Hoima districts. Caregivers of children with viral loads above 1000 copies were purposively sampled and engaged in five focus group discussions (FGD). The FGD guide highlighted questions on challenges that caregivers face and the kind of support they required to improve children’s ART adherence. Thematic analysis using the inductive approach was used. All the transcripts were read, coded and emergent themes determined.

Results

Overall, 37 caregivers participated in five FGD, of whom 29 (78%) were female, 28 (76%) were HIV-infected and 25 (68%) were biological parents of the children. The elicited challenges were either in failure to attend the counselling sessions or in supporting adherence to medication. Individual and health system challenges such as competing priorities, logistics, poor quality of counselling and lack of reminders prevented attendance at counselling sessions. Five themes emerged as challenges to supporting adherence: i) environmental (school activities, working away from home), ii) personal (non-disclosure, stigma), iii) psychological (guilt), iv) financial (lack of food and transport) and v) child-related (fatigue and peer influence). Three major themes emerged for the support that caregivers needed namely: a) health system reforms (clinic appointments outside school hours, minimize ART drug stock outs and improve quality of counselling), b) psychosocial support (support with disclosure of HIV status to children and their families, more frequent peer support groups and parenting classes) and c) economic empowerment (training in vocational skills, school fees support and opportunities to initiate income generating activities).

Discussion and conclusion

To achieve viral suppression, ART programs require targeted efforts to provide specific health facility requirements, psychological and economic needs of ART-treated children and their caregivers. Integration of HIV treatment with programs for orphans and vulnerable children may improve viral suppression rates.

Virologic failure in HIV-positive adolescents with perfect adherence in Uganda: a cross-sectional study

Background

Adolescents living with human immunodeficiency virus (HIV) die owing to acquired immune deficiency syndrome (AIDS)-related causes more than adults. Although viral suppression protects people living with HIV from AIDS-related illnesses, little is known about viral outcomes of adolescents in sub-Saharan Africa where the biggest burden of deaths is experienced. This study aimed to identify the factors associated with viral load suppression among HIV-positive adolescents (10-19 years) receiving antiretroviral therapy (ART) in Uganda.

Methods

We conducted a cross-sectional study among school-going, HIV-positive adolescents on ART from August to September 2016. We recruited 238 adolescents who underwent ART at a public health facility and had at least one viral load result recorded in their medical records since 2015. We collected the data of patients' demographics and treatment- and clinic-related factors using existing medical records and questionnaire-guided face-to-face interviews. For outcome variables, we defined viral suppression as < 1000 copies/mL. We used multivariate logistic regression to determine factors associated with viral suppression.

Results

We analyzed the data of 200 adolescents meeting the inclusion criteria. Viral suppression was high among adolescents with good adherence > 95% (adjusted odds ratio [AOR] 2.73, 95% confidence interval [95% CI, 1.09 to 6.82). However, 71% of all adolescents who did not achieve viral suppression were also sufficiently adherent (adherence > 95%). Regardless of adherence status, other risk factors for viral suppression at the multivariate level included having a history of treatment failure (AOR 0.26, 95% CI, 0.09 to 0.77), religion (being Anglican [AOR 0.19, 95% CI, 0.06 to 0.62] or Muslim [AOR 0.17, 95% CI, 0.05 to 0.55]), and having been prayed for (AOR 0.38, 95% CI, 0.15 to 0.96).

Conclusion

More than 70% of adolescents who experienced virologic failure were sufficiently adherent (adherence > 95). Adolescents who had unsuppressed viral loads in their initial viral load were more likely to experience virologic failure upon a repeat viral load regardless of their adherence level or change of regimen. The study also shows that strong religious beliefs exist among adolescents. Healthcare provider training in psychological counseling, regular and strict monitoring of adolescent outcomes should be prioritized to facilitate early identification and management of drug resistance through timely switching of treatment regimens to more robust combinations.
