Factors influencing adherence to paediatric antiretroviral therapy in Portharcourt, South- South Nigeria

'I take the drugs… to make the sickness to move out of me': key populations' and service provider perspectives about facilitators and barriers to ART adherence and retention in care in Nigeria

BACKGROUND

Adherence to antiretroviral therapy (ART) has individual and public health benefits and is critical to improving life expectancy, achieving viral suppression, and reducing the risk of HIV transmission. This qualitative study explored the experience of receiving care as well as perceived facilitators and barriers of treatment initiation, retention in ART care, and adherence to treatment.

METHODS

In-depth interviews were conducted among 28 men who have sex with men (MSM) and female sex workers (FSWs) receiving ART services in Lagos and Benue states. Key informant interviews were also conducted among 16 service providers engaged in counselling, clinical care, and ART treatment for MSM and FSWs. The Social Ecology Model guided the exploration of perceived barriers and facilitators of treatment initiation, retention in ART care and adherence to treatment. Qualitative data analysis was managed using NVIVO 11 software and themes were analysed using thematic analysis.

RESULTS

We found that the key barriers to ART adherence were low motivation to comply with medication regimen, work commitments, socioeconomic factors, stigma, negative provider attitude and distance to health facilities. Facilitators of adherence identified include the desire to live a productive life, strong family support and participation in support group programs. Comprehensive adherence counselling, support group programs and an effective follow-up system were factors identified by service providers as key to facilitating adherence.

CONCLUSION

To be effective, ART programs must address the unique challenges key populations face in accessing treatment and achieving optimal adherence regarding establishing a strong support system and follow-up. Community level interventions that support a stigma-free environment are critical to sustaining engagement in care.

Forgetting to Take Medication, Treatment Adherence and Their Relationship with Viral Load Suppression Among People Living with HIV in the Kilimanjaro Region, Tanzania

Background

Antiretroviral therapy (ART) adherence is crucial for virological suppression and positive treatment outcomes among people living with HIV (PLHIV), but remains a challenge in ensuring patients achieve and sustain viral load suppression. Despite the recommended use of digital tools medications uptake reminders, the contribution of forgetting to take medication is unknown. This study investigated the contribution of forgetting to take medication on the total missed medication and its effects on detectable viral load (VL).

Methods

This mixed-method research was conducted among children, adolescents, pregnant, and breastfeeding women living with HIV on ART in northern Tanzania. Forgetting to take medication constituted reporting to have missed medication due to forgetfulness. A multivariable logistic regression model was used to estimate the adjusted odds ratio (AOR) with a 95% confidence interval (CI) to determine the contribution of forgetting medication intakes on total missed medication and other factors associated with having a detectable VL.

Results

Of 427 respondents, 33.3% were children, 33.4% adolescents, and 33.3% pregnant and breastfeeding women, whose median age (interquartile range) was 9 (7-12), 18 (16-18), and 31 (27-36) years, respectively. Ninety-two (22.3%) reported missing medication over the past month, of which 72 (17.9%) was due to forgetting. Forgetting to take medication (AOR: 1.75 95% CI: 1.01-3.06) and being on second-line regimen (AOR: 2.89 95% CI: 1.50-5.55) increased the chances of a detectable VL, while females had lower chances of detectable VL (AOR: 0.62 95% CI: 0.41-0.98). The themes on the reasons for forgetting to take medication from qualitative results included being busy with work and the importance of reminders.

Conclusion

Forgetting to take medication is common among PLHIV and an important predictor of a detectable VL. This calls for the use of automated short message services (SMS) reminders or Digital Adherence Tools with reminders to improve and promote good ART adherence among PLHIV.

Disclosure of HIV status and adherence to antiretroviral treatment in children and adolescents from Lomé and Abidjan

Introduction

in Africa, the proportion of minors with AIDS is ever increasing and adherence to treatment protocols is still suboptimal. The study investigated the conditions of HIV status disclosure and adherence to treatment in patients < 19 in two West African cities.

Methods

in 2016, thirteen health professionals and four parents filled out questionnaires to identify problems and solutions relative to disclosure of HIV status and adherence to treatment in 208 children and adolescents seen at University Hospitals in Abidjan (Ivory Coast) and Lomé (Togo).

Results

medians (extrema) of patients´ ages at start and end of status disclosure process were 10 (8-13) and 15 (13-17.5) years. In 61% of cases, disclosure was made individually after preparation sessions. The main difficulties were: parents´ disapproval, skipped visits, and rarity of psychologists. The solutions proposed were: recruiting more full-time psychologists, improving personnel training, and promoting patients´ "clubs". One out of three respondents was not satisfied with patients´ adherence to treatments. The major reasons were: intake frequencies, frequent omissions, school constraints, adverse effects, and lack of perceived effect. Nevertheless, 94% of the respondents confirmed the existence of support groups, interviews with psychologists, and home visits. To improve adherence, the respondents proposed increasing the number of support groups, sustaining reminder phone calls and home visits, and supporting therapeutic mentoring.

Conclusion

despite persisting disclosure and adherence problems, appropriate measures already put into practice still need to be taken further, especially through engaging psychologists, training counsellors, and promoting therapeutic support groups.

Brief Report: Long-Term Clinical, Immunologic, and Virologic Outcomes Among Early-Treated Children With HIV in Botswana: A Nonrandomized Controlled Clinical Trial

BACKGROUND

Early antiretroviral treatment (ART) improves outcomes in children, but few studies have comprehensively evaluated the impact of ART started from the first week of life.

METHODS

Children diagnosed with HIV within 96 hours of life were enrolled into the Early Infant Treatment Study in Botswana and followed on ART for 96 weeks. Nevirapine, zidovudine, and lamivudine were initiated; nevirapine was switched to lopinavir/ritonavir between weeks 2-5 in accordance with gestational age. Clinical and laboratory evaluations occurred at weeks 1, 2, 4, 8, 12, 24, 36, 48, 60, 72, 84, and 96.

FINDINGS

Forty children initiated ART at a median of 2 (IQR 2, 3) days of life; 38 (95%) completed follow-up through 96 weeks, and 2 (5%) died between 12 and 24 weeks. ART was well tolerated; 9 children (24%) experienced a grade 3 or 4 hematologic event, and 2 (5%) required treatment modification for anemia. The median 96-week CD4 count was 1625 (IQR 1179, 2493) cells/mm 3 with only 5/38 (13%) having absolute counts <1000 cells/mm 3 . Although 23 (61%) had at least one visit with HIV-1 RNA ≥40 copies/mL at or after 24 weeks, 28 (74%) had HIV-1 RNA <40 copies/mL at the 96-week visit. Median cell-associated HIV-1 DNA at 84/96-week PBMCs was 1.9 (IQR 1.0, 2.6) log 10 copies/10 6 cells. Pre-ART reservoir size at birth was predictive of the viral reservoir at 84/96 weeks.

INTERPRETATION

Initiation of ART in the first week of life led to favorable clinical outcomes, preserved CD4 cell counts, and low viral reservoir through 96 weeks of life.

Psychosocial Support Programme Improves Adherence and Health Systems Experiences for Adolescents on Antiretroviral Therapy in Mpumalanga Province, South Africa

(1) Background: Psychosocial support (PSS) plays a significant role in persistent adherence to and retention in antiretroviral therapy (ART) for adolescents living with the human immunodeficiency virus (ALHIV). This paper qualitatively explores the experiences of ALHIV on ART, who participated in a PSS programme in five public primary healthcare facilities in Mpumalanga Province in South Africa during the COVID-19 pandemic. (2) Methods: Data were collected through 24 focus group discussions with 173 ALHIV on ART and subjected to inductive thematic analysis. Informed consent was obtained before all data collection. (3) Results: The PSS programme facilitated the process of full HIV disclosure to these adolescents with the support of parents/guardians while motivating adherence through peer support groups and health education for improved treatment literacy. Participants reported positive health systems experiences, improved healthcare provider-client relations, and prompt access to health services. (4) Conclusions: The PSS programme successfully kept ALHIV engaged in ART care despite the health service disruptions encountered during the COVID-19 pandemic. We recommend rigorous evaluation of the effects of the PSS intervention on adherence to and retention in ART among ALHIV in HIV-endemic settings.

Factors associated with HIV viral suppression among adolescents in Kabale district, South Western Uganda

Background

The goal of antiretroviral therapy is to achieve sustained human immune deficiency virus (HIV) viral suppression. However, research on factors associated with viral load suppression among adolescents in low and middle-income countries is limited. The objectives of this study were to determine HIV viral suppression levels among adolescents in Kabale district and the associated clinical, adherence and psychosocial factors.

Methods

Cross-sectional and retrospective cohort study designs were used. Two hundred and forty-nine adolescents living with HIV that attended clinics between September and October 2019 at nine health facilities were interviewed and their medical records reviewed. A data abstraction tool was used to collect clinical data from adolescent’s clinical charts, face to face interviews were conducted using semi-structured questionnaire adopted from the HEADS tool and in-depth interviews conducted with ten key informants. Qualitative data was analyzed using thematic content analysis. Logistic regression was used to determine the magnitude by which clinical and psychosocial factors influence viral load suppression. Odds Ratios (ORs) were used for statistical associations at 95% confidence interval considering statistical significance for p-values less than 0.05. Qualitative data collected from Key informants to support our quantitative findings was analyzed using thematic content analysis.

Results

HIV viral suppression among (n = 249) adolescents was at 81%. Having no severe opportunistic infections was associated with viral load suppression among adolescent living with HIV (OR = 1.09; 95%CI [1.753–4.589]; p<0.001) as well as having no treatment interruptions (OR = 0.86; 95% CI [2.414–6.790]; p = 0.004). Belonging to a support group (OR = 1.01; 95% CI [1.53–4.88]; P = 0.020), having parents alive (OR = 2.04; 95% CI[1.02–4.12]; P = 0.047) and having meals in a day (OR = 5.68; C.I = 2.38–6.12, P = 0.010), were significantly associated to viral load suppression. The findings also indicated that long distances from health facilities, transport challenges and unprofessional conduct of health workers that make adolescent unwelcome at health facilities negatively affected viral suppression among adolescents.

Conclusion

The findings indicate that HIV viral suppression among adolescents on ART was at 81%. Kabale district was likely not to achieve the third 90 of the UNAIDS 90-90-90 global target for this population category. The findings further indicate that having no severe opportunistic infection and no treatment interruptions, good nutrition status, peer support and support from significant others, were highly associated with viral load suppression.

Outcomes of HIV Positive Children and Adolescents Initiated on Antiretroviral Treatment in Nigeria (2007-2016)

Background: This manuscript aimed to examine treatment outcomes of HIV-positive children and adolescents. Methods: We retrospectively analyzed data of a sample of patients aged 0–19 years who initiated ART (October 2007–September 2016) in participating sites in 30 states and the Federal Capital Territory in Nigeria. Results: Among 4006 patients alive at the end of the follow up period, 138 (3.4%) were LTFU. Adolescents had a significantly higher risk of being LTFU than children aged 3–5 years (HR 2.47 [95% CI 1.40-4.34]). Patients with advanced disease had a significantly higher risk of being LTFU (Stage IV HR, 3.66 [95% CI: 2.00-6.68]). On average, optimal ART refill adherence was met by 67.3% of patients. Conclusion: Our findings suggest that focusing on preventing and managing advanced disease and interventions supporting adolescents when transferring to adult care is warranted.

Factors Associated with Viral Suppression Among Adolescents on Antiretroviral Therapy in Homa Bay County, Kenya: A Retrospective Cross-Sectional Study

Background

Despite the success in initiating adolescents living with HIV on antiretroviral therapy (ART), questions remain about factors affecting viral suppression. In Kenya, only 63% of adolescents (aged 10–19 years) on ART had achieved viral suppression in 2016. We investigated factors associated with viral suppression among adolescents initiated on ART before November 30, 2017 in Homa Bay County, Kenya.

Methods

A retrospective cross-sectional analysis of 908 adolescents registered on ART for at least 6 months and with at least one documented viral load in the last 12 months, in six health facilities in Homa Bay County was conducted. Data were extracted from the electronic medical records and exported into an excel spreadsheet. Bivariate and multivariate logistic regression analyses were conducted to identify factors associated with viral suppression and adjust for confounding, using Stata 12.0.

Results

Out of all participants, 80% (726) had achieved viral suppression (<1,000 copies of viral RNA/mL of blood at latest viral load count). After adjusting for other covariates, adolescents with good adherence to ART (AOR=2.3, 95% CI=1.38–3.84) and a most recent CD4 count of above 500 cells/mm³ (AOR=1.87, 95% CI=1.13–3.08), were more likely to be virally suppressed. Adolescents on second line ART treatment (AOR=0.45, 95% CI=0.28–0.73) and having inadequate adherence to ART (AOR=0.26, 95% CI=0.11–63) were less likely to be virally suppressed.

Conclusion

Viral suppression for adolescents on ART in this study is significantly higher than the national prevalence in 2016 (80% vs 63%), but it is still below the WHO target of 90%. Enhanced adherence support for adolescents on ART should be implemented to improve long-term adherence. Specific interventions are needed to “rescue” adolescents on second-line ART regimens who may have a history of poor adherence.

Social Networks and Barriers to ART Adherence Among Young Adults (18-24 years) Living with HIV at Selected Primary Health Facilities of South-Western Uganda: A Qualitative Study

Background

Young adults living with HIV (YALWH) struggle to maintain high levels of adherence to antiretroviral therapy (ART) because of numerous barriers. This study describes the social networks of YALWH (18–24 years), their barriers to ART adherence, and the perceived role of social networks in overcoming those barriers.

Methods

This study used a qualitative descriptive research design. Twenty-three (23) YALWH who were on ART for a period of greater than one (1) month and had consented to participate in the study were purposively selected from two primary health care facilities in southwestern Uganda. We held four (4) focus group discussions with the YALWH over 5 weeks between the 24th of July and 7th September 2020. Data were audio recorded, transcribed, and entered in Microsoft word 2010. Using the content analysis techniques, data were inductively coded and categories or themes developed.

Results

Most YALWH belonged to bonding (family, friends, and neighbors), followed by bridging (informal groups), and linking (health professionals) social networks, respectively. Most YALWH, irrespective of gender, had close connections with their mothers or elder sisters. The commonest form of bridging networks was informal community groups that provided financial services, whereas the linking ones comprised health professionals’ directly involved in HIV patient care such as nurses, counselors, and their affiliates (expert clients or clinic based peer supporters), who occasionally acted as bonding networks. Structural barriers to ART adherence (eg, stigma) were the most cited, followed by medication- (eg, pill burden), and patient-related barriers (eg, non-disclosure of HIV status). Bonding networks were perceived to help overcome patient, medication, and structural barriers to ART adherence. Bridging networks overcame structural and medication-related barriers to ART adherence. Linking networks were perceived to help overcome some health systems and medication-related barriers to ART adherence.

Conclusion

Bonding social networks seem to play a prominent role in overcoming numerous barriers to ART adherence compared with bridging and linking social networks.

Support services available for elderly women caring for people living with HIV and AIDS in Masindi District, Uganda

In sub-Saharan Africa, HIV/AIDS remains a big challenge and a leading cause of death among young adults, its main productive human resource. Hence, increasing the demand for care and support services by the epidemic infected and affected people. As a result, elderly persons, especially women are burdened to provide care and support; a midst disintegrated family support system and the inability of public and private sectors to adequately address their needs. The current qualitative study examined the support services available for elderly women caring for people living with HIV/AIDS in Masindi district, Uganda. A purposive sampling method was used to recruit 24 participants. In-depth interviews were conducted with 18 elderly women caregivers and 6 key informants. Findings indicated that the elderly women caregivers were at least receiving support from two major sectors; including the informal (family, friends, neighbors, religious and community groups) and formal (The Aids Support Organisation- TASO and the government) support systems. However, this support was not consistent and efficient for optimal caregiving. Therefore, more needs to done by making both the informal and formal support systems fully available for elderly caregivers for HIV/AIDS people, thus, benefiting from direct intervention and support services to help meet their care needs.

Levels of Adherence and Associated Factors Among Children on ART Over Time in Northwest, Ethiopia: Evidence from a Multicenter Follow-Up Study

Background

Despite the increased availability of antiretroviral therapy (ART), its success depends on a high level of adherence to a life-long antiretroviral therapy. However, the extent and factors associated with adherence to ART are not well known, especially in the current study setup. Therefore, this study aimed to assess the level of adherence and associated factors among children on ART in Northwest, Ethiopia.

Methods

A retrospective follow-up study was conducted on human immunodeficiency virus (HIV)-infected children receiving ART at South Gondar public hospitals. Children receiving ART from January 1, 2015, to November 30, 2020, were included in the study. A computer-generated simple random sampling technique was employed. The data were entered into the EpiData version 3.1 and analyzed by STATA 14 statistical software. Bivariable logistic regression was fitted for each predictor variable. Moreover, those variables having a p-value ≤0.25 in bivariate analysis were fitted into a multivariable logistic regression model. P-value <0.05 was used to declare significance.

Results

A total of 363 HIV-infected children were involved in the study. From 363 HIV-infected children, the level of adherence to ART was found to be 78.2%, 95% CI (73.6, 82.2). TB co-infection [adjusted odds ratio (AOR) = 3.8, 95% CI (1.41, 10.1)], short duration on ART (AOR = 3.4, 95% CI (1.60, 7.20)), treatment failure (AOR = 10.2, 95% CI (3.95, 26.2)), and Zidovudine containing ART regimen (AOR = 3.5, 95% CI (1.1, 10.9)) were significant predictors of poor adherence.

Conclusion

The current study showed that the level of adherence to ART was found to be low TB co-infection, short duration of ART, Zidovudine-containing ART regimen, and treatment failure were found to be significantly associated with poor adherence. Further studies on adherence rate and its determinants with multiple adherence measurements using prospective and multicenter studies were recommended.

The initiation of human immunodeficiency virus treatment for children at different levels of care

Background: The human immunodeficiency virus (HIV) pandemic increased the demand for health care resources in South Africa. To decrease the burden on specialised facilities, the Department of Health decentralised antiretroviral (ARV) management. In the uMgungundlovu district, adult HIV primary care services reported lower rates of HIV viral load (VL) suppression after initiation of ARVs compared to other levels of care. The aim of the study was to evaluate paediatric HIV services in the same district. Methods: Four ARV clinics, at different levels of care, initiating and monitoring paediatric HIV infection treatment in uMgungundlovu district, KwaZulu Natal, were selected: primary healthcare services, general practitioner services, general paediatric services and subspecialist infectious diseases services were included. Paediatric patients newly diagnosed between January 2014 and June 2015 were included in the study. The rate of HIV VL suppression at one year after treatment initiation was the primary outcome measure. A total of 377 patients were included, 35 at the nurse-led primary care clinic, 25 at the general practitioner-led primary care clinic, 156 at the paediatrician-led secondary care clinic, and 161 at the HIV paediatric subspecialist-led tertiary care clinic. Of the 377 patients, 154 (59.9%) achieved VL suppression at one year, with 75% (18/24), 61.9% (13/21), 51.7% (60/116) and 66.7% (63/96) achieving HIV VL suppression at the four clinic types, respectively. Conclusion: HIV VL suppression rates were variable, but did not differ statistically across levels of health care. Outcomes were not improved by initiation in specialist or subspecialist-led clinics, which supports the strategy of increasing access by decentralising HIV care for paediatric patients.

Loss to follow-up correction increased mortality estimates in HIV-positive people on antiretroviral therapy in Mozambique

OBJECTIVES

People living with human immunodeficiency virus (HIV) on antiretroviral therapy (ART) may be lost to follow-up (LTFU), which hampers the assessment of outcomes. We estimated mortality for patients starting ART in a rural region in sub-Saharan Africa and examined risk factors for death, correcting for LTFU.

STUDY DESIGN AND SETTING

We analyzed data from Ancuabe, Mozambique, where patients LTFU are traced by phone and home visits. We used cumulative incidence functions to estimate mortality and LTFU. To correct for LTFU, we revised outcomes based on tracing data using different inverse probability weights (maximum likelihood, Ridge regression, or Bayesian model averaging). We fitted competing risk models to identify risk factors for death and LTFU.

RESULTS

The analyses included 4,492 patients; during 8,152 person-years of follow-up, 486 patients died, 2,375 were LTFU, 752 were traced, and 603 were found. At 4 years after starting ART, observed mortality was 11.9% (95% confidence interval [CI]: 10.9-13.0), but 23.5% (95% CI: 19.8-28.0), 21.6% (95% CI: 18.7-25.0), and 23.3% (95% CI: 19.7-27.6) after correction with maximum likelihood, Ridge regression, and Bayesian model averaging weights, respectively. The risk factors for death included male sex, lower CD4 cell counts, and more advanced clinical stage.

CONCLUSION

In ART programs with substantial LTFU, mortality estimates need to take LTFU into account.

Factors affecting adherence to treatment in children living with HIV

Background:

With the successful introduction of ART, the life expectancy of children living with HIV (CLHIV) is substantially increased. However, strict compliance is a necessary step to begin with as noncompliance is again associated with its own demerits of incomplete suppression and decreasing the overall survival of the patients.

Aims:

The aim of this study was to measure factors associated with adherence to ART among CLHIV.

Materials and Methods:

This is a 1-year follow-up study conducted from November 2012 to December 2013. A total of 171 children between 18 months and 15 years living with HIV and on ART attending the two ART centers of Delhi were enrolled in the study. Adherence and factors affecting adherence were obtained from the study participants using a semi-structured interview schedule.

Statistical Analysis Used:

Collected data were transformed into variables and analyzed into SPSS. All observations were in terms of mean, median, standard deviations, percentages, and proportions. Tests of significance such as Chi-square test and t-test were applied wherever required.

Results:

In nearly 89% of the study participants, adherence to ART was ≥95% at the end of the study. The most common reason for nonadherence was forgetfulness (59%), and 57% of the parents/caretakers were facing monetary problems. Long distance, greater duration to reach center, and unavailability of the parents/caretakers were also quoted as problems.

Conclusion:

Adherence is genesis to successful treatment outcome and is strongly associated with availability of support by their parents/caretakers. Professional help along with guidance and encouragement is required not only at the caretaker level but also to the family as a whole.

A cross-sectional study on caregivers' perspective of the quality of life and adherence of paediatric HIV patients to highly active antiretroviral therapy

Background

Poor compliance to highly active antiretroviral therapy (HAART) can result in the poor quality of life in children living with Human immunodeficiency virus/Acquired immunodeficiency syndrome (HIV/AIDS) because of low plasma drug concentration and the possibility of drug resistance. This study evaluates the response of caregivers for determination of adherence and the four quality of life domains in children (aged 14 years and under) on HAART.

Methods

We conducted a cross-sectional study of 188 children, each accompanied by their caregivers at Ola During Children’s Hospital and Makeni Government Hospital between September and November 2016. Adherence to HAART and Quality of life was assessed using the WHO Quality of life summary questionnaire (WHOQOL-BREF). We obtained ethical approval from the Sierra Leone Ethics and Scientific Review Committee.

Results

The study revealed 5.9% adherence amongst paediatric patients, and a strong association of adherent patients(p = 0.019*) to the physical health domain (mean = 64.61 SD = 8.1). Caregiver HIV status showed a strong association with the physical (mean = 58.3, SD = 11.7 and p = 0.024*), and psychological health domains (mean = 68.2, SD = 14.7 and p = 0.001). Caregiver type (mother/father/sibling) accompanying child to hospital also showed strong associated with the physical (mean = 58.0, SD = 10.6, p <  0.001), psychological (mean 68.2 SD = 14.81 p <  0.001) and environmental health domains (mean = 59.7, SD = 13.47, p <  0.001). Further regression analysis showed a strong association with physical health domain for HIV positive caregivers (p = 0.014) and adherent paediatric patients (p = 0.005). Nuclear family also showed a strong association with psychological (p <  0.001) and environmental (p = 0.001) health domains.

Conclusion

This study showed a strong association between the quality of life domains and the involvement of nuclear family caregiver, HIV-positive caregiver and adherence to HAART. Our study suggests that the involvement of any member of the nuclear family, HIV positive parents and patient adherence to therapy can improve the quality of life of paediatric HIV/AIDS patients on highly active antiretroviral therapy in the two hospitals.

<p>Differential Self-Reported Determinants to Antiretroviral Therapy Adherence: Findings from Caregivers of Children Under Five Years Living with Human Immunodeficiency Virus Infection Attending Al-Sabah Hospital, South Sudan</p>

Aim/Objective

This study explored the caregivers’ self-reported determinants of antiretroviral therapy (ART) adherence among children under five years living with human immunodeficiency virus (HIV) infection attending Al-Sabah Hospital, South Sudan.

Methods

A cross-sectional study of 126 caregivers of HIV-infected children under five years was conducted at Al-Sabah Hospital, South Sudan. Data were collected using an interviewer-administered questionnaire. The self-reported adherence was measured as a binary variable using binary logistic regression. Only variables that were significant at bivariate analysis were analyzed at multivariate level and interpreted using the odds ratios (p< 0.05).

Results

Out of 126 caregivers with HIV-infected children, 38 (30.2%) did not adhere to ART. Of the proportion that adhered to ART (88, 69.8%), 49 (55.7%) were male. Most of the children (52, 59.1%) were above two years, but under five years. Fifty (56.8%) of those who adhered had completed 3 months on ART, and the majority were at WHO stage-1 of HIV infection. Analysis of the determinants indicated that children’s duration on ART (p=0.001), type of ART regimen (single, double or triple therapy) (p=0.065), type of work done by the caregiver to earn a living (p-value 0.003), time a child was initiated on ART (p=0.002), caregiver–child relationship (p=0.002), caregiver-spousal support (p=0.019), type of support obtained whether monetary or not (p=0.000), when the child was started on ART (p=0.004), the person administering ART (p=0.010), the type of ARVs administered (p=0.001), the caregiver detecting ART side effects (p=0.000), types of adverse effects suffered by the child (p=0.043), time of receiving ART (p=0.047), use of western medicine (p=0.043), healthcare cadre (p=0.002), the kind of attention the healthcare provider offered (p=0.015), and improvements in quality of HIV services (p=0.001) were significantly associated with ART adherence.

Conclusion

The study findings indicated that ART adherence among HIV-infected children under five years was suboptimal. This will necessitate continuous engagement and education of caregivers on the prominence of adhering to ART.

Treatment failure and associated factors among first line patients on highly active antiretroviral therapy in Ethiopia: a systematic review and meta-analysis

BACKGROUND

Antiretroviral therapy (ART) restores immune function and reduces human immunodeficiency virus (HIV) related adverse outcomes. The results of previous studies in Ethiopia were replete with inconsistent findings; nonexistence of national representative figures and determinant factors are found as significant gap. The aim of this systematic review and meta-analysis was to assess the existing evidence on ART treatment failure and associated factors in Ethiopia.

METHODS

Relevant studies on ART treatment failure were retrieved from international databases: PubMed, Google Scholar, Scopus, and Science Direct systematically prior to March 14, 2019. All identified studies reporting the proportion of first line treatment failure among HIV patients in Ethiopia were included. Two authors independently extracted all necessary data using a standardized data extraction format. A random-effects model was used to calculate pooled estimates and associated factors in Stata/se Version-14. The Cochrane Q test statistics and I 2 tests were used to assess the heterogeneity of the studies.

RESULTS

From 18 articles reviewed; the pooled proportion of first line treatment failure among ART users in Ethiopia was 15.3% (95% CI: 12, 18.6) with (I 2 = 97.9%, p < 0.001). The subgroup analysis by World Health Organization (WHO) treatment failure assessment criteria were carried out, accordingly the highest prevalence (11.5%) was noted on immunological and the lowest (5.8%) was observed virological treatment failure. We had found poor adherence (OR = 8.6, 95% CI: 5.6, 13.4), not disclosed (OR = 2.1, 95% CI: 1.5, 3.0), advanced WHO clinical stage III/IV (OR = 2.4, 95% CI: 1.5, 3.8), change in regimen (OR = 2.5, 95% CI: 1.6, 3.9) and being co-infected (OR = 2.56, 95% CI: 2.2, 3.0) were statistically significant factors for treatment failure.

CONCLUSION

In this study, treatment failure among ART users in Ethiopia was significant. Adherence, co-infection, advanced WHO clinical stage, regimen change, and disclosure are determinant factors for treatment failure. Therefore, improve drug adherence, prevent co-infection, close follow up, and prevent HIV-drug resistance are required in future remedial efforts.

Adherence to combination antiretroviral therapy among orphaned children in Dar es Salaam, Tanzania

Background

Adherence to combination antiretroviral therapy (cART) among HIV-infected children is often complicated by various factors including medication formulation, dosing frequency, drug toxicities, age and developmental stage, psychosocial and behavioural characteristics of both children and caregivers and can additionally be complicated by being an orphan.

Objectives

This study was aimed at determining the factors and the extent of their influence on cART adherence among HIV-infected orphaned children attending Care and Treatment Centres (CTCs) in Dar es Salaam, Tanzania.

Methods

A cross-sectional study was performed, which assessed adherence in HIV-positive orphaned children aged 2–14 years receiving nevirapine (NVP) based cART for at least 6 months. Data was collected using questionnaires administered to primary caregivers of HIV-infected orphaned children, the review of medical files, and the laboratory measurement of NVP plasma concentrations and CD4 counts. Adherence to cART was determined based on caregivers’ self-report, consistency of clinic attendance and NVP plasma concentrations.

Results

Among the 216 enrolled orphaned children, adherence to cART was found to be 79.6%, 82.9% and 72.2% respectively based on caregivers’ self-report, clinic attendance and NVP plasma levels. Significant reductions in NVP concentrations (< 3 µg/mL) were seen among children with poor immunological outcomes, poor clinic attendance (p < 0.05) and were suggested by caregivers’ self-reported adherence (p = 0.06). Adherence challenges identified by caregivers included financial constraints (87.5%), lengthy waiting times at clinics (75.5% spent > 2 h at the clinic) and low HIV knowledge among caregivers.

Conclusion

Significant numbers of HIV-infected orphans have poor adherence to cART ranging between 17% and 28% based on different assessment methods. Inadequate caregiver knowledge of HIV/AIDS, long clinic waiting times and forgetfulness were identified as barriers to cART adherence in these orphans.

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.

High prevalence of non-adherence to antiretroviral therapy among undisclosed HIV-infected children in Ghana

Adherence to antiretroviral therapy (ART) remains one of the greatest obstacles in pediatric HIV care. We sought to determine the prevalence of adherence to ART among undisclosed HIV-infected children and adolescents in Ghana. We analyzed baseline data from HIV-infected children and adolescents aged 7-18 years old enrolled in the SANKOFA Pediatric HIV disclosure intervention study in Ghana. Antiretroviral medication adherence was measured using caregiver 3-day recall; child 3-day recall; and pharmacy records for antiretroviral time-to-refill. Four hundred and twenty child-caregiver dyads were enrolled from January 2013 to June 2016. The median adherence (interquartile range), as measured by time-to-refill, was 93.2% (68.0%-100.0%). However, only 47.5% of children had ≥95% adherence ("good adherence") using time-to-refill data. Children of caregivers who had received secondary or higher level of education versus no school (aOR, 2.90, 95% Confidence Interval, CI 1.29-6.56), p = 0.010) or elementary education only (aOR, 2.20, CI, 1.24-3.88, p = 0.007) were more likely to have "good adherence" (≥95%). In this cohort of children unaware of their HIV positive status, median ART adherence rate was sub-optimal (by World Health Organization definition) while 38% had poor adherence (<85%).

Adherence to Highly Active Antiretroviral Therapy Among Children in Ethiopia: A Systematic Review and Meta-analysis

Adherence to highly active antiretroviral therapy (HAART) is the mainstay of the strategy in reducing morbidity and mortality of HIV-infected children. Different primary studies were conducted in Ethiopia. Thus, we aimed to conduct a meta-analysis of the national prevalence of optimal adherence to HAART in children. In addition, associated factors of HAART adherence were reviewed. A weighted inverse variance random-effects model was applied. The 88.7 and 93.7% of children were adhering to HAART at 07 and 03 days prior to an interview respectively. The subgroup analysis showed that HAART adherence was 93.4% in Amhara, 90.1% in Addis Ababa and 87.3% in Tigray at 07 days prior to an interview. Our study suggests that, within short window reported time, adherence to HAART in Ethiopian children may be in a good progress. Emphasis on specific adherence interventions need further based on individual predictors to improve overall HAART adherence of children.

Greater retention in care among adolescents on antiretroviral treatment accessing "Teen Club" an adolescent-centred differentiated care model compared with standard of care: a nested case-control study at a tertiary referral hospital in Malawi

Introduction

There are numerous barriers to the care and support of adolescents living with HIV (ALHIV) that makes this population particularly vulnerable to attrition from care, poor adherence and virological failure. In 2010, a Teen Club was established in Zomba Central Hospital (ZCH), Malawi, a tertiary referral HIV clinic. Teen Club provides ALHIV on antiretroviral treatment (ART) with dedicated clinic time, sexual and reproductive health education, peer mentorship, ART refill and support for positive living and treatment adherence. The purpose of this study was to evaluate whether attending Teen Club improves retention in ART care.

Methods

We conducted a nested case–control study with stratified selection, using programmatic data from 2004 to 2015. Cases (ALHIV not retained in care) and controls (ALHIV retained in care) were matched by ART initiation age group. Patient records were reviewed retrospectively and subjects were followed starting in March 2010, the month in which Teen Club was opened. Follow‐up ended at the time patients were no longer considered retained in care or on 31 December 2015. Cases and controls were drawn from a study population of 617 ALHIV. Of those, 302 (48.9%) participated in at least two Teen Club sessions. From the study population, 135 (non‐retained) cases and 405 (retained) controls were selected.

Results

In multivariable analyses, Teen Club exposure, age at the time of selection and year of ART initiation were independently associated with attrition. ALHIV with no Teen Club exposure were less likely to be retained than those with Teen Club exposure (adjusted odds ratio (aOR) 0.27; 95% CI 0.16, 0.45) when adjusted for sex, ART initiation age, current age, reason for ART initiation and year of ART initiation. ALHIV in the age group 15 to 19 were more likely to have attrition from care than ALHIV in the age group 10 to 14 years of age (aOR 2.14; 95% CI 1.12, 4.11).

Conclusions

This study contributes to the limited evidence evaluating the effectiveness of service delivery interventions to support ALHIV within healthcare settings. Prospective evaluation of the Teen Club package with higher methodological quality is required for programmes and governments in low‐ and middle‐income settings to prioritize interventions for ALHIV and determine their cost‐effectiveness.

High self-reported non-adherence to antiretroviral therapy amongst adolescents living with HIV in Malawi: barriers and associated factors

Introduction: Globally adolescents and young adults account for more than 40% of new HIV infections, and HIV-related deaths amongst adolescents increased by 50% from 2005 to 2012. Adherence to antiretroviral therapy (ART) is critical to control viral replication and preserve health; however, there is a paucity of research on adherence amongst the growing population of adolescents living with HIV/AIDS (ALHIV) in Southern Africa. We examined levels of self-reported ART adherence, barriers to adherence, and factors associated with non-adherence amongst ALHIV in Malawi.

Methods: Cross-sectional study of 519 ALHIV (12–18 years) attending two large HIV clinics in central and south-eastern Malawi. Participants self-reported missed doses (past week/month), barriers to adherence, and completed questionnaires on past traumatic events/stressors, disclosure, depression, substance use, treatment self-efficacy, and social support. Biomedical data were retrieved from existing medical records. Multivariate logistic regression was performed to identify factors independently associated with self-reported ART adherence (7 day recall).

Results: The mean age of participants (SD) was 14.5 (2) years and 290 (56%) were female. Of the 519 participants, 153 (30%) reported having missed ART doses within the past week, and 234 (45%) in the past month. Commonly reported barriers to adherence included forgetting (39%), travel from home (14%), busy with other things (11%), feeling depressed/overwhelmed (6%), feeling stigmatized by people outside (5%) and within the home (3%). Factors found to be independently associated with missing a dose in the past week were drinking alcohol in the past month (OR 4.96, 95% CI [1.41–17.4]), missed clinic appointment in the past 6 months (OR 2.23, 95% CI [1.43–3.49]), witnessed or experienced violence in the home (OR 1.86, 95% CI [1.08–3.21]), and poor treatment self-efficacy (OR 1.55 95% CI [1.02–2.34]). Sex and age were not associated with adherence.

Conclusions: In our study, nearly half of all ALHIV reported non-adherence to ART in the past month. Violence in the home or alcohol use in the past year as well as poor treatment self-efficacy were associated with worse adherence. Sub-optimal adherence is a major issue for ALHIV and compromise treatment outcomes. Programmes specifically tailored to address those challenges most pertinent to ALHIV may help improve adherence to ART.

Assessment of Antiretroviral Treatment Adherence among Children Attending Care at a Tertiary Hospital in Southeastern Nigeria

Background. Adherence is the strongest predictor of successful treatment outcome among children infected with HIV. Our aim was to assess the antiretroviral drugs adherence status of HIV-infected children attending care at a tertiary hospital in Southeastern Nigeria. Method. The study involved a cross-sectional survey of 210 HIV-infected children attending care at a tertiary hospital in Southeastern Nigeria using self-report method of assessment. Optimal ART adherence is defined as patient taking not missing more than 1 dose of combined antiretroviral therapy medication in the preceding 2 weeks prior to the study. Result. A majority of the subjects 191 (91%) had good adherence. There was a significant relationship between adherence and patient educational level (p = 0.004), duration of treatment (p = 0.001), drug administrator (p = 0.005), and orphan status (p = 0.001). The motivating factor for adherence was "not falling sick as before" while stigma was the most discouraging factor. Conclusion. The adherence level in this study was good. Stigma was an important reason given by patient/caregivers for nonadherence. There is need for concerted effort in addressing this barrier to improve adherence and prevent the emergence of drug resistance and treatment failure.

Improved Adherence to Antiretroviral Therapy Observed Among HIV-Infected Children Whose Caregivers had Positive Beliefs in Medicine in Sub-Saharan Africa

A high level of adherence to antiretroviral treatment is essential for optimal clinical outcomes in HIV infection, but measuring adherence is difficult. We investigated whether responses to a questionnaire eliciting caregiver beliefs in medicines were associated with adherence of their child (median age 2.8 years), and whether this in turn was associated with viral suppression. We used the validated beliefs in medicine questionnaire (BMQ) to measure caregiver beliefs, and medication event monitoring system caps to measure adherence. We found significant associations between BMQ scores and adherence, and between adherence and viral suppression. Among children initiating Antiretroviral therapy (ART), we also found significant associations between BMQ ‘necessity’ scores, and BMQ ‘necessity-concerns’ scores, and later viral suppression. This suggests that the BMQ may be a valuable tool when used alongside other adherence measures, and that it remains important to keep caregivers well informed about the long-term necessity of their child’s ART.

Magnitude and predictors of antiretroviral treatment failure among HIV-infected children in Fiche and Kuyu hospitals, Oromia region, Ethiopia: a retrospective cohort study

The objective of the study was to assess the magnitude and predictors of first‐line antiretroviral treatment failure among HIV‐infected children. A retrospective cohort study was conducted between January 2006 and December 2015. All pediatric patients of <15 years old and who took at least 6 months of ART in Fiche and Kuyu hospitals of Oromia region, Ethiopia were included in the study. Collected data were entered and analyzed using SPSS version 20. Multivariable logistic regression was employed to identify predictors of treatment failure. Data of 269 children were analyzed and majority (53.9%) of the children were males with a mean age of 9.8 ± 3.64 years. Based on the two WHO criteria, overall ART failure was found to be 51 (18.8%), of which 33 (12.26%) had clinical and 18 (6.69%) had immunologic failures. The mean time to the detection of treatment failure was 41 ± 24.96 months. Children's age between 6 and 9 years (AOR = 0.26, 95% CI: 0.09, 0.72) was protective toward treatment failure, while lost to follow‐up (AOR = 7.54, 95% CI: 2.35, 24.16), died (AOR = 22.22, 95% CI: 3.75, 131.54), transferred out (AOR = 3.34, 95% CI: 1.41, 7.87), suboptimal adherence to ART (AOR = 4.85, 95% CI: 1.82, 12.93), baseline CD4 count of <50 cells/mm³ (AOR = 4.28, 95% CI: 3.49, 5.9), and WHO advanced clinical stage (AOR = 2.46, 95% CI: 1.14, 5.31) were found to be predictors of treatment failure. The study revealed that the treatment failure is high and the mean time to develop treatment failure is short. The predictors for treatment failure were suboptimal adherence, lost to follow‐up, transferred out, initial CD4 count <50 cells/mm³, initial WHO stages 3 and 4. On the other hand, being in the age of 6–9 years is protective from developing treatment failure as compared to the other age category.

Keeping kids in care: virological failure in a paediatric antiretroviral clinic and suggestions for improving treatment outcomes

The burden of paediatric HIV in South Africa is extremely high. Antiretrovirals (ARVs) are now widely accessible in the country and the clinical emphasis has shifted from initiation of treatment to retention in care. This study describes the cumulative virological failure rate amongst children on ARVs in a peri-urban clinic, and suggests ways in which clinics and partners could improve treatment outcomes. The study was conducted by the non-profit organisation HOPE Cape Town Association. A retrospective file audit determined the cumulative virological failure rate, that is, the sum of all children with a viral load >1000 copies/ml, children on monotherapy, children who had stopped treatment, children lost to follow-up (LTFU) and children who had died. Interviews were conducted with a purposive sample of 12 staff members and a random sample of 21 caregivers and 4 children attending care. Cumulative virological failure rate was 42%, with most of those children having been LTFU. Both staff and caregivers consistently identified pharmacy queues, ongoing stigma and unpalatable ARVs as barriers to adherence. Staff suggestions included use of adherence aids, and better education and support groups for caregivers. Caregivers also requested support groups, as well as "same day" appointments for caregivers and children, but rejected the idea of home visits. Simple, acceptable and cost-effective strategies exist whereby clinics and their partners could significantly reduce the cumulative virological failure rate in paediatric ARV clinics. These include actively tracing defaulters, improving education, providing support groups, and campaigning for palatable ARV formulations.

Impact of HIV-Status Disclosure on Adherence to Antiretroviral Therapy Among HIV-Infected Children in Resource-Limited Settings: A Systematic Review

Pediatric HIV remains a significant global health dilemma, especially in resource-constrained nations. As access to ART increases around the world, areas of concern in pediatric HIV treatment include age-appropriate disclosure of HIV status to children and development of adherence habits over time. This review was conducted to synthesize quantitative associations reported between disclosure and adherence among children living with HIV in resource-limited settings. An electronic database search of PubMed, MEDLINE and Cochrane returned 1348 results after removal of duplicates, 14 of which were found to meet inclusion criteria. Review of these reports showed conflicting results regarding the impact of disclosure on adherence, with 5 showing no association, 4 showing a negative impact of disclosure on adherence, and 5 showing positive benefits of disclosure for adherence habits. Thus, there was no clear consensus on the effect, if any, that disclosure has on medication adherence. Longitudinal, prospective research needs to be conducted to evaluate further impacts that disclosure may have on adherence habits over time, and interventions must be structured to link the two processes together in order to maximize health benefit to the child or adolescent.

Caregiver-reported antiretroviral therapy non-adherence during the first week and after a month of treatment initiation among children diagnosed with HIV in Ethiopia

To achieve optimal virologic suppression for children undergoing antiretroviral therapy (ART), adherence must be excellent. This is defined as taking more than 95% of their prescribed doses. To our knowledge, no study in Ethiopia has evaluated the level of treatment adherence at the beginning of the child's treatment. Our aim was therefore to evaluate caregiver-reported ART non-adherence among children and any predictors for this during the early course of treatment. We conducted a prospective cohort study of 306 children with HIV in eight health facilities in Ethiopia who were registered at ART clinics between 20 December 2014 and 20 April 2015. The adherence rate reported by caregivers during the first week and after a month of treatment initiation was 92.8% and 93.8%, respectively. Our findings highlight important predictors of non-adherence. Children whose caregivers were not undergoing HIV treatment and care themselves were less likely to be non-adherent during the first week of treatment (aOR = 0.17, 95% CI: 0.04, 0.71) and the children whose caregivers did not use a medication reminder after one month of treatment initiation (aOR = 5.21, 95% CI: 2.23, 12.16) were more likely to miss the prescribed dose. Moreover, after one month of the treatment initiation, those receiving protease inhibitor (LPV/r) or ABC-based treatment regimens were more likely to be non-adherent (aOR = 12.32, 95% CI: 3.25, 46.67). To promote treatment adherence during ART initiation in children, particular emphasis needs to be placed on a baseline treatment regimen and ways to issue reminders about the child's medication to both the health care system and caregivers. Further, large scale studies using a combination of adherence measuring methods upon treatment initiation are needed to better define the magnitude and predictors of ART non-adherence in resource-limited settings.

Assessing Adherence to Antiretroviral Therapy in a Rural Paediatric Cohort in KwaZulu-Natal, South Africa

Achieving optimal adherence to ARV's in a rural paediatric population is challenging. Monitoring adherence by frequent viral load assay is not always feasible or sustainable in rural communities. A relatively cheaper, reliable, valid and sustainable measure of adherence for children is required for routine management. This study retrospectively assessed adherence outcomes using monthly pill count and viral load data, including reasons reported for non-adherence, in a paediatric cohort in rural KwaZulu-Natal, South Africa. Between 2008 and 2013, 78 children, mean age of 7.1 years, were enrolled in the CAPRISA 052 AIDS Treatment Programme. Monthly treatment adherence by pill count was categorized as either high (≥95 %) or low (<95 %). Overall median monthly adherence to treatment by pill count was 87.8 % at month 6, 88.9 % at month 12 and 90.8 % at month 24. However, the proportion of children with an undetectable viral load (<400 copies/ml) was 84.0 % (63/74), 86.6 % (58/67), and 84.5 % (49/58) at the three time points respectively. Agreement between pill count and viral load showed that only 33.9, 36. 3 and 30.6 % of children were truly adherent by pill count at months 6, 12 and 24 respectively. In conclusion, this treatment programme demonstrated that adherence of >95 % by pill count is not an ideal indicator of virological suppression in children aged 6 months to 13 years. Viral load assessment remains the gold standard for assessing treatment success in this age group.

An update on the HIV treatment cascade in children and adolescents

PURPOSE OF REVIEW

To provide an update on the HIV treatment cascade in children and adolescents. We reviewed the literature on the steps in the cascade, for the period 2014-2015.

RECENT FINDINGS

There remains high attrition of children with regards to early testing and linking those patients who are positive to early treatment. Barriers to screening and testing in children and adolescents are multifactorial. Linkage to pre-antiretroviral therapy care and retention in care are the main steps at which attrition occurs. There are a number of new formulations available for use in adolescents and children which offer more options for antiretroviral therapy treatment. Adherence levels appear to be reasonable in Africa and Asia; however, achieving viral load suppression remains a challenge.

SUMMARY

We have a long way to go to achieve decreased attrition at each step of the cascade and retain patients in care. Recent improvements in each step of the cascade are bringing us closer to achieving treatment success.

Prediction of HIV Virologic Failure Among Adolescents Using the Pediatric Symptom Checklist

Psychosocial dysfunction is a risk factor for treatment non-adherence among children and adolescents. A previous study showed that high scores on the Pediatric Symptom Checklist (PSC) were associated with a history of HIV virologic failure. We assessed whether high scores on the PSC could predict virologic failure in HIV-infected youth. Caregivers of 234 adolescents between the ages of 10 and 16 years were asked to complete a PSC at baseline. Elevated PSC scores were associated with virologic failure in the subsequent 6 months. PSC scores may help guide resource utilization when viral load monitoring is limited.

Contemporary issues on the epidemiology and antiretroviral adherence of HIV-infected adolescents in sub-Saharan Africa: a narrative review

Introduction

Adolescents are a unique and sometimes neglected group in the planning of healthcare services. This is the case in many parts of sub-Saharan Africa, where more than eight out of ten of the world's HIV-infected adolescents live. Although the last decade has seen a reduction in AIDS-related mortality worldwide, largely due to improved access to effective antiretroviral therapy (ART), AIDS remains a significant contributor to adolescent mortality in sub-Saharan Africa. Although inadequate access to ART in parts of the subcontinent may be implicated, research among youth with HIV elsewhere in the world suggests that suboptimal adherence to ART may play a significant role. In this article, we summarize the epidemiology of HIV among sub-Saharan African adolescents and review their adherence to ART, emphasizing the unique challenges and factors associated with adherence behaviour.

Methods

We conducted a comprehensive search of online databases for articles, relevant abstracts, and conference reports from meetings held between 2010 and 2014. Our search terms included “adherence,” “compliance,” “antiretroviral use” and “antiretroviral adherence,” in combination with “adolescents,” “youth,” “HIV,” “Africa,” “interventions” and the MeSH term “Africa South of the Sahara.” Of 19,537 articles and abstracts identified, 215 met inclusion criteria, and 148 were reviewed.

Discussion

Adolescents comprise a substantial portion of the population in many sub-Saharan African countries. They are at particular risk of HIV and may experience worse outcomes. Although demonstrated to have unique challenges, there is a dearth of comprehensive health services for adolescents, especially for those with HIV in sub-Saharan Africa. ART adherence is poorer among older adolescents than other age groups, and psychosocial, socio-economic, individual, and treatment-related factors influence adherence behaviour among adolescents in this region. With the exception of a few examples based on affective, cognitive, and behavioural strategies, most adherence interventions have been targeted at adults with HIV.

Conclusions

Although higher levels of ART adherence have been reported in sub-Saharan Africa than in other well-resourced settings, adolescents in the region may have poorer adherence patterns. There is substantial need for interventions to improve adherence in this unique population.

'HIV is like a tsotsi. ARVs are your guns': associations between HIV-disclosure and adherence to antiretroviral treatment among adolescents in South Africa

OBJECTIVES

WHO guidelines recommend disclosure to HIV-positive children by school age in order to improve antiretroviral therapy (ART) adherence. However, quantitative evidence remains limited for adolescents. This study examines associations between adolescent knowledge of HIV-positive status and ART-adherence in South Africa.

DESIGN

A cross-sectional study of the largest known community-traced sample of HIV-positive adolescents. Six hundred and eighty-four ART-initiated adolescents aged 10-19 years (52% female, 79% perinatally infected) were interviewed.

METHODS

In a low-resource health district, all adolescents who had ever initiated ART in a stratified sample of 39 health facilities were identified and traced to 150 communities [n = 1102, 351 excluded, 27 deceased, 40 (5.5%) refusals]. Quantitative interviews used standardized questionnaires and clinic records. Quantitative analyses used multivariate logistic regressions, and qualitative analyses used grounded theory for 18 months of interviews, focus groups and participant observations with 64 adolescents, caregivers and healthcare workers.

RESULTS

About 36% of adolescents reported past-week ART nonadherence, and 70% of adolescents knew their status. Adherence was associated with fewer opportunistic infection symptoms [odds ratio (OR) 0.55; 95% CI 0.40-0.76]. Adolescent knowledge of HIV-positive status was associated with higher adherence, independently of all cofactors (OR 2.18; 95% CI 1.47-3.24). Among perinatally infected adolescents who knew their status (n = 362/540), disclosure prior to age 12 was associated with higher adherence (OR 2.65; 95% CI 1.34-5.22). Qualitative findings suggested that disclosure was undertaken sensitively in clinical and family settings, but that adults lacked awareness about adolescent understandings of HIV status.

CONCLUSION

Early and full disclosure is strongly associated with improved adherence amongst ART-initiated adolescents. Disclosure may be an essential tool in improving adolescent adherence and reducing mortality and onwards transmission.

Adherence to antiretroviral therapy and its associated factors among children at South Wollo Zone Hospitals, Northeast Ethiopia: a cross-sectional study

BACKGROUND

Poor adherence to antiretroviral therapy negatively affects the suppression of viral replication. It increases risks of drug resistance, treatment failure, Acquired Immuno Deficiency Syndrome (AIDS)-related morbidity and mortality among children. This study assessed the level of adherence to antiretroviral therapy and its associated factors among children at hospitals in South Wollo Zone, Northeast Ethiopia.

METHODS

An institution-based cross-sectional study was conducted among Human Immunodeficiency Virus (HIV)-infected children in April 2013. A total of 464 children who were taking Antiretroviral Therapy (ART) in the hospitals were included. Data were collected using pretested and structured questionnaires using a face-to-face interview method. Descriptive and summary statistics were employed. Bivariate and multiple logistic regressions were computed. Odds ratios and their 95% confidence intervals were computed to determine the level of significance.

RESULTS

Of the 464 study samples, 440 children with their caregivers were included in the final analysis. A total of 78.6% of the caregivers reported that their children were adherent to antiretroviral therapy in the month prior to the interview. Caregivers' knowledge about antiretroviral treatment [AOR = 2.72(95% CI: 1.82, 5.39)], no current substance use of the caregivers [Adjusted Odds Ratio (AOR) = 2.21(95% Confidence Interval (CI): 1.34, 7.13)], proximity to the health care facility [AOR = 2.31(95% CI: 1.94, 4.63)], if the child knows HIV-positive status [AOR = 3.47(95% CI: 2.10, 6.81)] and caregiver's educational status [AOR = 0.59(95% CI: 0.21, 0.82)] were significantly and independently associated with adherence of children to antiretroviral therapy.

CONCLUSION

Adherence of antiretroviral therapy in this study was comparable to other studies conducted in developing countries. Caregiver's knowledge about antiretroviral therapy, no current use of substances, close proximity to health facilities, and letting child's know his/her HIV status improves adherence to antiretroviral therapy. Health care providers should educate caregivers about antiretroviral therapy and encourage HIV positive status disclosure to the child.
