Factors Associated with the Failure of First & Second-Line Antiretroviral Therapies in Cambodian HIV-1 Infected Children

BACKGROUND:
Little is known about the efficacy of first and and second-line antiretroviral therapies (ART) for HIV-1 infected children in resource limited Southeast Asian settings. Previous studies have shown that orphans are at a higher risk for virological failure (VF) in Cambodia. Consequently most of them required transfer to second-line ART. We assessed the factors associated with VF among HIV-1 infected children who were either under first-line (mostly 3TC + D4T + NVP) or under second-line (mostly ABC + DDI + LPV) therapies at a referral hospital in Cambodia.

METHODS:
A case-control study was conducted from February to July 2013 at the National Pediatric Hospital among HIV-1 infected children (aged 1-15 years) under second-line ART (cases) or first-line (matched controls at a ratio of 1:3) regimens. Children were included if a HIV-1 RNA plasma viral load (VL) result was available for the preceding 12 months. A standardized questionnaire explored family sociodemographics, HIV history, and adherence to ART. Associations between VF (HIV-1 RNA levels ≥1000 copies/ml) and the children's characteristics were assessed using bivariate and multivariate analyses.

RESULTS:
A total of 232 children, 175 (75.4 %) under first-line and 57 (24.6 %) under second-line ART, for a median of 72.0 (IQR: 68.0-76.0) months, were enrolled. Of them, 94 (40.5 %) were double orphans and 51 (22.0 %) single orphans, and 77 (33.2 %) were living in orphanages. A total of 222 children (95.6 %) were deemed adherent to ART. Overall, 18 (7.7 %; 95 % CI 4.6-11.9) showed a VF, 14 (8.6 %; 95 % CI 4.8-14.0) under first-line and 4 (7.0 %; 95 % CI 1.9-17.0) under second-line ART (p = 0.5). Their median CD4 percentage was 8 % (IQR 2.9-12.9) at ART initiation. Children under second-line ART were older; more often double orphans, and had lower CD4 cell counts at the last control. In the multivariate analysis, having the last CD4 percentage below 15 % was the only factor associated with VF for ART regimen separately or when combined (OR 40.4; 95 % CI 11-134).

CONCLUSIONS:
The pattern of risk factors for VF in children is changing in Cambodia. Improved adherence evaluation and intensified monitoring of children with low CD4 counts is needed to decrease the risk of VF.

Tensions in Communication between Children on Antiretroviral Therapy and Their Caregivers: A Qualitative Study in Jinja District, Uganda

Introduction
HIV treatment and disclosure guidelines emphasize the importance of communicating diagnosis and treatment to infected children in ways that are appropriate to children’s developmental stage and age. Minimal attention, however, has been given to communication challenges confronted by HIV-infected children and their caregivers. This study examined the tensions between children and their caregivers arising from differing perspectives regarding when and what to communicate about antiretroviral therapy (ART).

Methods
This qualitative study was conducted between November 2011 and December 2012 and involved 29 HIV-infected children aged 8–17 years on ART and their caregivers. Data were collected through observations and in-depth interviews, which took place in homes, treatment centres and post-test clubs. Children and caregivers were sampled from among the 394 HIV-infected children and (their) 393 caregivers who participated in the cross-sectional survey that preceded the qualitative study. ATLAS.ti. Version 7 was used in the management of the qualitative data and in the coding of the emerging themes. The data were then analyzed using content thematic analysis.

Results
While the children felt that they were mature enough to know what they were suffering and what the medications were for, the caregivers wanted to delay discussions relating to the children’s HIV diagnosis and medication until they felt that the children were mature enough to deal with the information and keep it a secret and this caused a lot of tension. The children employed different tactics including refusing to take the medicines, to find out what they were suffering from and what the medications were for. Children also had their own ideas about when, where and with whom to discuss their HIV condition, ideas that did not necessarily coincide with those of their caregivers, resulting in tensions.

Conclusions
Guidelines should take into consideration differing perceptions of maturity when recommending ages at which caregivers should communicate with their children about diagnosis and ART. Health care providers should also encourage caregivers to recognize and respect children’s efforts to learn about and manage their condition. Children’s questions and expressions of feelings should be treated as openings for communication on these issues.

Summary of the topics in the in-depth interview guide.
TOPICSSUB-TOPICS
Experiences considered most important in the life of the childSchooling/lack of schooling experiences; a typical week of schooling; vacation/holiday-what they do, who they visit; involvement in social events e.g. sports, drama, post-test clubs, relations with peers; whom they confide in when they have good or bad news.
Socio-demographic informationAge, birth/parents, education status, residence i.e. who the child lives with/family relations, relationship to caregiver, employment of caregiver, living conditions, number of siblings.
Health & medicine experiencesWhy and how often they go to the treatment centres; who escorts them; what takes place when they go; what medicines they are given and how often they take them; how long they have been taking the medicines; where they keep the medicines; who helps them to take the medicine; who they talk to about the medicine at home, school, neighbourhood; what they talk about; who else at home takes similar medicines; what they understand by the need to be on lifelong/daily medication
Learning about status/experiences of disclosureReasons they had been given for taking daily medicines; who told them; their experiences and reactions when they learnt reasons for taking daily medicines; how they came to know the illness/health condition for which they took daily medicines; who told them; what exactly they were told; how they were told; age at which they were told; their experiences/reactions when they were told about their illness; what they understand by having illness.
Communication about illness and treatment in different social spacesPeople who knew about their illness/health and medicines at home, school, in the neighborhood, and how they came to know; people they had told about their health and medicines; reasons for telling such people; people’s reactions when they were told; who they normally communicated with about their illness and treatment and where; who they think deserved to know about their illness and why; what they liked/disliked to hear about their health and medicines; questions/challenges of being on daily medicines; whom they talk to about these challenges; how they could be supported to live on daily medicines.

Predictors of Treatment Failure in HIV-Positive Children Receiving Combination Antiretroviral Therapy: Cohort Data From Mozambique and Uganda

Delays detecting treatment failure and switching to second-line combination antiretroviral therapy (cART) are often observed in human immunodeficiency virus (HIV)-infected children of low-middle-income countries (LMIC).

An observational study included HIV-infected children attending the Beira Central Hospital (Mozambique) and the Nsambya Hospital, Home Care Department (Uganda) evaluated clinical and immunological failure according to World Health Organization (WHO) 2006 guidelines. Baseline predictors for cART failure and for drug substitution were explored in unadjusted and adjusted Cox proportional hazard models.

Two hundred eighteen of 740 children with at least 24 weeks follow-up experienced treatment failure (29%; 95% confidence interval [CI] 26-33), with crude incidence of 20.0 events per 100 person-years (95% CI 17.5-22.9). Having tuberculosis co-infection or WHO stage 4, or starting a nontriple cART significantly increased risk of failure. Two hundred two of 769 (26.3%) children receiving cART substituted drug(s), with crude incidence of 15.4 events per 100 person-years (95% CI 13.4-17.7). Drug toxicity (18.3%), drug availability (17.3%), and tuberculosis drugs interaction (52, 25.7%) were main reported reasons, while only 9 (4%) patients switched cART for clinical or immunological failure. Children starting lamivudine-zidovudine-nevirapine or lamivudine-stavudine-efavirenz or lamivudine-zidovudine-efavirenz were more likely to have substitute drugs. Increased substitution was found in children with mild immunosuppression and tuberculosis co-infection at cART initiation as well as poor adherence before drug substitution.

Considerable delay in switching to second-line cART may occur despite an observed high rate of failure. Factors including WHO clinical stage and tuberculosis co-infection should be evaluated before starting cART. Toxicity and drug adherence should be monitored to minimize drug substitution in LMIC.
