Viral suppression and adherence among HIV-infected children and adolescents on antiretroviral therapy: results of a multicenter study

Impact of enhanced adherence counselling on viral re-suppression among adolescents and young persons with persistent viremia

OBJECTIVE

Kenya ART guidelines recommend three sessions of enhanced adherence counselling (EAC) following detectable viral load. The objective of this study was to assess completion of EAC sessions and factors associated with viral re-suppression amongst adolescents and young persons (AYPs) with persistent viremia in Western Kenya.

METHODS

A retrospective analysis of routinely collected data abstracted from viral load registers was done. AYP with persistent viremia (consecutive viral load ≥1000 copies/ml) between October 2017 to September 2019 were followed for 12 months; those with more than one follow-up viral load results were analyzed. EAC was satisfactory if at least three sessions attended, barriers identified and addressed. Morisky scores 0 and at least 1 indicated optimal and sub-optimal adherence, respectively. Logistic regression models were used to assess predictors of viral load suppression (VLS).

RESULTS

Of 124 AYPs with persistent viremia, 118 (95.2%) had documented follow-up viral load results and 119 (96%) completed three EAC sessions. Overall, 55 (47%) clients re-suppressed during the study period. AYPs who had satisfactory EAC sessions had higher odds of achieving VLS [odds ratio (OR) = 3.7, 95% confidence interval (CI): 1.6-8.1]. Similarly, AYPs with an optimal adherence had eight times (OR = 8.1, 95% CI: 3.5-18.5) higher odds of achieving VLS, and those who were suppressed at 6 months post-ART initiation had higher odds of achieving VLS at 12-months (OR = 2.5, 95% CI: 1.1-5.8).

CONCLUSION

Satisfactory EAC sessions and optimal ART adherence was strongly associated with viral re-suppression among AYPs with persistent viremia. Continued support to EAC intervention is critical to improve treatment outcome among AYP living with HIV.

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.

ART history prior to conception: trends and association with postpartum disengagement from HIV care in Khayelitsha, South Africa (2013-2019): a retrospective cohort study

INTRODUCTION

In recent years, the expansion of HIV treatment eligibility has resulted in an increase in people with antiretroviral therapy (ART) experience prior to pregnancy but little is known about postpartum engagement in care in this population. We examined differences in disengagement from HIV care after delivery by maternal ART history before conception.

METHODS

We analysed data from people living with HIV (aged 15-49) in Khayelitsha, South Africa, with ≥1 live birth between April 2013 and March 2019. We described trends over time in ART history prior to estimated conception, classifying ART history groups as: (A) on ART with no disengagement (>270 days with no evidence of HIV care); (B) returned before pregnancy following disengagement; (C) restarted ART in pregnancy after disengagement; and (D) ART new start in pregnancy. We used Kaplan-Meier curves and proportional-hazards models (adjusted for maternal age, number of pregnancy records and year of delivery) to examine the time to disengagement from delivery to 2 years postpartum.

RESULTS

Among 7309 pregnancies (in 6680 individuals), the proportion on ART (A) increased from 19% in 2013 to 41% in 2019. The proportions of those who returned (B) and restarted (C) increased from 2% to 13% and from 2% to 10%, respectively. There was a corresponding decline in the proportion of new starts (D) from 77% in 2013 to 36% in 2019. In the first recorded pregnancy per person in the study period, 26% (95% CI 25-27%) had disengaged from care by 1 year and 34% (95% CI 33-36%) by 2 years postpartum. Individuals who returned (B: aHR 2.10, 95% CI 1.70-2.60), restarted (C: aHR 3.32, 95% CI 2.70-4.09) and newly started ART (D: aHR 2.41, 95% CI 2.12-2.74) had increased hazards of postpartum disengagement compared to those on ART (A).

CONCLUSIONS

There is a growing population of people with ART experience prior to conception and postpartum disengagement varies substantially by ART history. Antenatal care presents an important opportunity to understand prior ART experiences and an entry into interventions for strengthened engagement in HIV care.

Factors associated with adherence to antiretroviral therapy in HIV-infected subjects and the use of indicators to characterize the treatment adhesion profile

At present, there is no gold standard to assess patient adherence to combination antiretroviral therapy (cART). Therefore, this study aimed to characterize the epidemiological profile, delineate adherence indicators, and identify factors associated with adherence and delays in obtaining medication in patients registered at the Specialized Assistance Service in HIV/AIDS in Brazil. This is a descriptive study based on secondary data obtained from official databases of the Brazilian Ministry of Health. Adherence and delay were measured by the frequency of cART medication acquisition in 24 months, and a multivariate linear regression model was developed to identify the factors associated with non-adherence and delays. In 50.2% of the subjects, the viral load remained undetectable throughout the study period. Only 12.4% of patients were fully adherent to cART. Regarding indicators, a value of 0.83 was found for adherence, 0.09 for delay in days, and 0.21 for the number of times the patient was late to obtain the medication. The multivariate analysis showed that males, age between 20 and 59 years, having not changed the cART, and the presence of ≥1000 HIV RNA copies/mL were predictive factors for adherence and delays (P≤0.01). We demonstrated that monitoring cART medication distribution is possible using health indicators, and identifying the factors associated with poor adherence to cART helps characterize patients at higher risks of unsuccessful therapy.

The effect of group support psychotherapy on adherence to anti-retroviral therapy and viral suppression among HIV positive young people: Study protocol for a pilot randomized controlled trial

Background

Several studies have demonstrated an association between psychological risk factors and HIV disease progression. However, there is limited information on the use of psychological interventions to improve HIV treatment outcomes in young people living with HIV.

Objective

This pilot trial aims to evaluate the feasibility, acceptability and preliminary effectiveness of group support psychotherapy in improving adherence to anti-retroviral therapy and viral suppression in young people living with HIV in Uganda.

Methods

We recruited 120 young people with HIV, aged 10–18 years, who had non-viral suppression 6 months after initiating first-line anti-retroviral therapy (ART) from community based HIV clinics in Kitgum district, northern Uganda. Participants were randomly assigned to receive GSP plus IAC (N = 60) or IAC alone (N = 60). Primary outcomes will be indicators of feasibility and acceptability as well as preliminary effectiveness of GSP in improving ART adherence and viral suppression analysed by intention to treat using cluster-adjusted t tests and permutation tests. Secondary outcomes will be measures of depression, anxiety and cost-effectiveness.

Results

The trial has been approved by the Makerere College of Health Sciences School of Health Sciences Research Ethics Committee, and the Uganda National Council of Science and Technology. Recruitment began in June 2021 and 120 young people living with HIV with their adult caregivers have been recruited to the trial. An analysis of baseline and 6-month data is in progress. The results of this trial will not only be presented at national and international conferences but also submitted for publication in peer-reviewed journals and as a report to the funding agencies.

Conclusions

This pilot trial will provide critical evidence to support the ongoing mental health integration into routine HIV care in Uganda.

Caregivers' psychosocial assessment for identifying HIV-infected infants at risk of poor treatment adherence: an exploratory study in southern Mozambique

Psychosocial support (PSS) to caregivers of HIV-infected infants on antiretroviral treatment (ART) is crucial to ensure ART adherence and sustained long-term viral suppression in children. A specific approach including tools to monitor and understand adherence behavior and risk factors that prevent optimal treatment compliance are urgently needed. This qualitative exploratory study, conducted in southern Mozambique, monitored the infants' viral response trajectories during 18 months follow-up, as a measure of adherence, reviewed the caregiver's PSS session notes and the answers to a study questionnaire, to analyze whether the standard PSS checklist applied to infants' caregivers can identify barriers influencing their adherence. Only 9 of 31 infants had sustained virologic response. Reported factors affecting adherence were: difficulties in drugs administration, shared responsibility to administer treatment; disclosure of child's HIV status to family members but lack of engagement; mother's ART interruption and poor viral response. In conclusion, we found that the standard PSS approach alone, applied to caregivers, was lacking focus on many relevant matters that were identified by the study questionnaire. A comprehensive patient-centered PSS package of care, including an adherence risk factor monitoring tool, tailored to caregivers and their children must be developed.

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.

HIV and Substance Use in Latin America: A Scoping Review

This scoping review aims to explore the interplay between substance use (SU) and HIV in Latin America (LA). Database searches yielded 3481 references; 196 were included. HIV prevalence among people who used substances (PWUS) ranged from 2.8–15.2%. SU definitions were variable throughout studies, and thus data were not easily comparable. In 2019, only 2% of new HIV infections were attributed to injection drug use (IDU) in LA. Factors associated with HIV among PWUS included being female, IDU and homelessness, and PWUS were likely to engage in risky sexual behaviors, start antiretroviral treatment late, have poor adherence, have treatment failure, be lost to follow-up, have comorbidities, and experience higher mortality rates and lower quality of life, as has been reported in PLWH with SU in other regions. Five intervention studies were identified, and only one was effective at reducing HIV incidence in PWUS. Interventions in other regions have varying success depending on context-specific characteristics, highlighting the need to conduct more research in the LA region. Though progress has been made in establishing SU as a major concern in people living with HIV (PLWH), much more is yet to be done to reduce the burden of HIV and SU in LA.

Past and current status of adolescents living with HIV in South Africa, 2005-2017

OBJECTIVES

This paper reports HIV prevalence, incidence, progress towards the UNAIDS (90-90-90) targets, and HIV drug resistance among adolescents living with HIV in South Africa. We conducted secondary analyses using data extracted from the South African national HIV prevalence surveys (2005-2017). Analyses were stratified by sex and age (10-14 and 15-19-years), presenting weighted descriptive statistics, and realised totals.

RESULTS

HIV prevalence increased from 3.0% in 2012 to 3.7% in 2017, translating to 360 582 (95% CI 302 021-419 144) HIV positive adolescents in 2017. Female adolescents bear a disproportionate HIV burden of 5.6% prevalence versus 0.7% for males. HIV incidence remained relatively stable. For the UNAIDS 90-90-90 targets, approximately 62.3% of adolescents knew their HIV status, 65.4% of whom were on antiretroviral therapy, and of these 78.1% on antiretroviral therapy had attained viral load suppression. There are knowledge gaps pertaining to the magnitude of perinatal infections and postnatal infections, and socio-behavioural risk factors for HIV transmission among adolescents in South Africa. There is still a need for focussed interventions targeting adolescent (1) gender disparities in HIV risk (2) screening for HIV, (3) sustained access and adherence to antiretroviral therapy and (3) retention in care to maintain viral load suppression.

Predictors of Viral Non-Suppression among Patients Living with HIV under Dolutegravir in Bunia, Democratic Republic of Congo: A Prospective Cohort Study

The Democratic Republic of the Congo adopted the integrase inhibitor dolutegravir (DTG) as part of its preferred first-line HIV treatment regimen in 2019. This study aimed to identify predictors of viral non-suppression among HIV-infected patients under a DTG-based regimen in the context of ongoing armed conflict since 2017 in the city of Bunia in the DRC. We conducted a cohort study of 468 patients living with HIV under DTG in all health facilities in Bunia. We calculated the proportion of participants with an HIV RNA of below 50 copies per milliliter. About three in four patients (72.8%) in this cohort had a viral load (VL) of <50 copies/mL after 6–12 months. After controlling for the effect of other covariates, the likelihood of having non-suppression remained significantly lower among the 25–34 age group and self-reported naïve patients with a baseline VL of ≥50 copies/mL. The likelihood of having non-suppression remained significantly higher among those who were at advanced stages of the disease, those with abnormal serum creatinine, those with high baseline HIV viremia over 1000 copies/mL, and the Sudanese ethnic group compared to the reference groups. This study suggests that we should better evaluate adherence, especially among adolescents and economically vulnerable populations, such as the Sudanese ethnic group in the city of Bunia. This suggests that an awareness of the potential effects of DTG and tenofovir is important for providers who take care of HIV-positive patients using antiretroviral therapy (ART), especially those with abnormal serum creatinine levels before starting treatment.

Measuring adherence to ARVs among HIV-positive adolescents in Cameroon: a comparative assessment of self-report and medication possession ratio methods

Introduction

adherence to ARV medications has been shown to improve treatment outcomes in HIV positive patients. Given that ARV treatment is lifelong, adherence has become a critical issue as it may reduce over time. Measuring adherence is therefore imperative in programming. There are different methods of measuring adherence each with its advantages and disadvantages, depending on the context and the time. This study therefore compares two widely used adherence measurement scales in Cameroon, namely, the self-report and the medication possession ration (MPR) methods.

Methods

the study was done in some selected health facilities of the North West and South West regions of Cameroon among adolescents on ARV. The study was designed as an analytical cross-sectional study with a record review component and systematic random sampling was used to select the participants. Adherence was measured through self-report and the medication possession ratio. Adolescents with adherence levels of at least 95% were considered adherent. Viral load suppression was considered as having the most recent viral load suppression results of less than 1000 copies per ml. The kappa statistics of inter-rate agreement was used to ascertain the difference between adherence as measured by self-report and MPR. The difference in adherence between the two scales was also compared using Fischer´s exact test and p-values were reported.

Results

the study shows that adherence level using the self-report technique is 82.9% while that of MPR was 73.4%. When compared using the using Kappa statistics, there was substantial agreement between the two scales of 66% (p=0.54). The results of both self-report adherence and MPR were also compared with viral load suppression and the difference between viral load suppression and MPR was significant (p<0.01). The difference in adherence between viral load suppression and the self-report measure also showed to be significant (p<0.01).

Conclusion

adherence from the self-report measure was higher than from MPR, but there was substantial agreement between the scales. Although there is no gold standard for adherence measurement, self-report or medication possession ratio could be used and complemented with laboratory markers like viral load counts.

HIV-related stigma among young people living with HIV transitioning to an adult clinic in a public hospital in Rio de Janeiro, Brazil

This study analyzes how experiences of HIV-related stigma are expressed among HIV-positive young people transitioning to an adult clinic, the health service, the family, the affective-sexual interactions, and their relationship with inequalities and social hierarchies. This research included 31 young people (median age 21) transitioning to an adult clinic (G1) and 12 young people (median age 30) who had already made this transition (G2), both monitored at a health service in Rio de Janeiro. Seventy percent of the 43 young people were women and 65% were infected by mother-to-child transmission. Young people answered questionnaires and participated in focus groups on AIDS stigma and transition to adulthood. Most reported discrimination associated with HIV stigma in daily life and health care. G1 young people showed more significant concern about the consequences of HIV disclosure and difficulties with treatment. The G2 accounts suggest that establishing marital relationships, including HIV-negative partners and children, linked to treatment access allowed resignifying the fear of stigmatization. The findings aim to guide the training and action of professionals involved in the prevention and care of young people living with HIV.

Understanding the influence of health systems on women's experiences of Option B+: A meta-ethnography of qualitative research from sub-Saharan Africa

We explored women's experiences of Option B+ in sub-Saharan African health facility settings through a meta-ethnography of 32 qualitative studies published between 2010 and 2019. First and second-order constructs were identified from the data and authors' interpretations respectively. Using a health systems lens, third-order constructs explored how the health systems shaped women's experiences of Option B+ and their subsequent engagement in care. Women's experiences of Option B+ services were influenced by their interactions with health workers, which were often reported to be inadequate and rushed, reflecting insufficient staffing or training to address pregnant women's needs. Women's experiences were also undermined by various manifestations of stigma which persisted in the absence of resources for social or mental health support, and were exacerbated by space constraints in health facilities that infringed on patient confidentiality. Sub-optimal service accessibility, drug stock-outs and inadequate tracing systems also shaped women's experiences of care. Strengthening health systems by improving health worker capacity to provide respectful and high-quality clinical and support services, improving supply chains and improving the privacy of consultation spaces would improve women's experiences of Option B+ services, thereby contributing to improved care retention. These lessons should be considered as universal test and treat programmes expand.

Supernatural Explanatory Models of Health and Illness and HIV Antiretroviral Therapy Use Among Young Men Who Have Sex with Men in China

BACKGROUND

In China, men who have sex with men (MSM) shoulder a disproportionate HIV burden. Early initiation and adherence to HIV antiretroviral therapy (ART) will be critical to reversing the HIV epidemic in China, but ART usage remains suboptimal among MSM diagnosed with HIV. One understudied but potentially important factor underpinning suboptimal ART usage is personal belief in supernatural explanatory models of health and illness (supernatural explanatory models). This study examines associations between beliefs in supernatural explanatory models and ART usage among MSM in China.

METHOD

In 2017, an online survey was distributed nationwide throughout China by gay community-based organizations. Eligible study participants were self-identified MSM between 16 and 30 years old who had tested positive for HIV and who had seen a doctor in the last 2 years. Beliefs in supernatural explanatory models were measured using a three-item scale developed specifically for the Chinese population (range, 3-15).

RESULTS

Of 73 participants, the majority were currently using ART (83.6%) and 42.5% expressed some endorsement of belief in supernatural explanatory models. However, among 21 participants with the strongest belief in supernatural explanatory models, prevalence of current ART usage was 61.9%. Stronger belief in supernatural explanatory models was significantly associated with lower likelihood of current ART usage (adjusted odds ratio = 0.52; 95% confidence interval = 0.13-0.75).

CONCLUSION

Belief in supernatural explanatory models may be a powerful predictor of ART usage among MSM living with HIV in China. Further studies are needed to corroborate these findings and elucidate mechanisms of association.

Unsatisfactory long-term virological suppression in human immunodeficiency virus-infected children in the Amazonas State, Brazil

INTRODUCTION:

Achieving viral suppression (VS) in children is challenging despite the exponential increase in access to antiretroviral therapy (ART). We evaluated VS in children >1 year of age and adolescents 5 years after they had begun ART, in Manaus, Amazonas state, Brazil.

METHODS:

HIV-infected, ART-naive children >1 year of age between 1999 and 2016 were eligible. Analysis was stratified by age at ART initiation: 1-5 y, >5-10 y, and >10-19 y. CD4⁺ T-cell count and viral load were assessed on arrival at the clinic, on ART initiation, and at 6 months, 1 year, 2 years, and 5 years after ART initiation. The primary outcome was a viral load <50 copies/mL 5 years after ART initiation.

RESULTS:

Ultimately, 121 patients were included. The mean age at diagnosis was 4.8 years (SD 3.5), mean CD4% was 17.9 (SD 9.8), and mean viral load was 4.6 log10 copies/ml (SD 0.8). Five years after ART initiation, the overall VS rate was 46.9%. VS by patient age group was as follows: 36.6% for 1-5 y, 53.3% for >5-10 y, and 30% for >10-19 y. Almost all children (90,4%) showed an increase in CD4%+ T cell count. There were no statistically significant predictors for detecting children who do not achieve VS with treatment. VS remained below 65% in all the evaluated periods.

CONCLUSIONS:

Considerable immunological improvement is seen in children after ART initiation. Further efforts are needed to maintain adequate long-term VS levels and improve the survival of this vulnerable population.

Challenges to achieving and maintaining viral suppression among children living with HIV

OBJECTIVES

The objective of this study was to determine the time to, and durability of, viral suppression, among Canadian children living with HIV after initiation of combination antiretroviral therapy (cART).

DESIGN

Prospective, multicenter Canadian cohort study (Early Pediatric Initiation Canada Child Cure Cohort), using both prospective and retrospectively collected data.

METHODS

Kaplan-Meir survival estimates with Cox regression were used to determine the time to and risk factors for viral suppression, defined as two consecutive undetectable viral loads (<50 copies/ml) at least 30 days apart after initiation of cART.

RESULTS

A total of 228 children were enrolled between December 2014 and December 2018. The time to viral suppression was significantly shorter among children initiating cART after 5 ≤ 5 vs. years or less of age [adjusted hazard ratio (aHR) 1.57, 95% confidence interval (CI) 1.13-2.20], among those born after 2010 vs. prior (aHR 1.71, 95% CI 1.04-2.79), and among those without child protection services involvement (aHR 1.44, 95% CI 1.03-2.01). Overall, 27% of children had a viral rebound within 3 years of achieving viral suppression; the risk of viral rebound was significantly lower among children initiating cART after 5 vs. 5 years or less of age [adjusted odds ratio (aOR): 0.32, 95% CI 0.13-0.81], those whose families had not received social assistance (aOR 0.16, 95% CI 0.06-0.46), and females vs. males (aOR 0.51, 95% CI 0.26-0.99).

CONCLUSION

Only 73% of the children in the Early Pediatric Initiation Canada Child Cure Cohort had maintained viral suppression 3 years after it was first achieved. Age at cART initiation, and socioeconomic factors were predictors of both time to viral suppression and risk of viral rebound in this cohort.

Long-term outcomes in perinatally HIV-infected adolescents and young adults on antiretroviral therapy: a review of South African and global literature

Paediatric antiretroviral programmes have been implemented globally for more than a decade, yet information on long-term treatment outcomes in perinatally HIV-infected adolescents is limited. Published literature on long-term treatment outcomes was reviewed, including virologic, immunologic and growth outcomes, as well as drug resistance and factors associated with drug resistance. Outcomes were compared between high-income countries and low- and middle-income countries (LMIC), with additional focus on South Africa, the country with the biggest HIV epidemic in the world and the largest treatment programme. Treatment outcomes varied but viral suppression results globally were generally concerning. No studies from LMIC have reported on outcomes after >10 years follow-up, demonstrating that further studies are needed.

A Longitudinal Study of Behavioral Risk, Adherence, and Virologic Control in Adolescents Living With HIV in Asia

BACKGROUND

Adolescents living with HIV (ALHIV) have poorer adherence and clinical outcomes than adults. We conducted a study to assess behavioral risks and antiretroviral therapy outcomes among ALHIV in Asia.

METHODS

A prospective cohort study among ALHIV and matched HIV-uninfected controls aged 12-18 years was conducted at 9 sites in Malaysia, Thailand, and Vietnam from July 2013 to March 2017. Participants completed an audio computer-assisted self-interview at weeks 0, 48, 96, and 144. Virologic failure (VF) was defined as ≥1 viral load (VL) measurement >1000 copies/mL. Generalized estimating equations were used to identify predictors for VF.

RESULTS

Of 250 ALHIV and 59 HIV-uninfected controls, 58% were Thai and 51% females. The median age was 14 years at enrollment; 93% of ALHIV were perinatally infected. At week 144, 66% of ALHIV were orphans vs. 28% of controls (P < 0.01); similar proportions of ALHIV and controls drank alcohol (58% vs. 65%), used inhalants (1% vs. 2%), had been sexually active (31% vs. 21%), and consistently used condoms (42% vs. 44%). Of the 73% of ALHIV with week 144 VL testing, median log VL was 1.60 (interquartile range 1.30-1.70) and 19% had VF. Over 70% of ALHIV had not disclosed their HIV status. Self-reported adherence ≥95% was 60% at week 144. Smoking cigarettes, >1 sexual partner, and living with nonparent relatives, a partner or alone, were associated with VF at any time.

CONCLUSIONS

The subset of ALHIV with poorer adherence and VF require comprehensive interventions that address sexual risk, substance use, and HIV-status disclosure.

Individual and neighborhood predictors of retention in care and viral suppression among Florida youth (aged 13-24) living with HIV in 2015

Youth aged 13‒24 are less likely to be retained in HIV care and be virally suppressed than older age groups. This study aimed to assess predictors of retention in HIV care and viral suppression among a population-based cohort of youth (N = 2872) diagnosed with HIV between 1993 and 2014 in Florida. We used generalized estimating equations to estimate prevalence ratios (PRs). Retention in care was defined as evidence of engagement in care (at least one laboratory test, physician visit, or antiretroviral therapy prescription refill), two or more times, at least three months apart during 2015. Viral suppression was defined as having evidence of a viral load <200 copies/ml among those in care during 2015. Among the 2872 youth, 65.4% were retained in care, and among those in care, 65.0% were virally suppressed. Older youth (18‒24 years old) and non-Hispanic Blacks (NHBs) were less likely to be retained in care, whereas those men who have sex with men, perinatal HIV transmission, living in low socioeconomic neighborhoods, and those diagnosed with AIDS before 2016 were more likely to be retained in care. Those diagnosed with AIDS before 2016 and NHBs were less likely to be virally suppressed, whereas those men who have sex with men and foreign-born persons were more likely to be virally suppressed. Results suggest the need for targeted retention and viral suppression interventions for NHB youth and older youth (18‒24 years-age).

HIV-seroconversion among HIV-1 serodiscordant married couples in Tanzania: a cohort study

Background

Heterosexual transmission is the main driver of the HIV epidemic in Tanzania. Only one estimate of the incidence rate of intra-marital HIV seroconversion in Tanzania has been reported and was derived from data collected between 1991 and 1995. Moreover, little is known about the specific risk factors for intra-marital seroconversion in Tanzania. Improved evidence around factors that increase the risk of HIV transmission to a serodiscordant spouse is needed to develop and improve evidence-based interventions. We sought to investigate the rate of intra-marital HIV seroconversion among HIV sero-discordant couples in Tanzania as well as its associated risk factors.

Methods

We identified all HIV positive individuals in the TAZAMA HIV-serosurvey cohort and followed up their serodiscordant spouse from 2006 to 2016. The rate of seroconversion was analyzed by survival analysis using non-parametric regressions with exponential distribution.

Results

We found 105 serodiscordant couples, 14 of which had a seroconverting spouse. The overall HIV-1 incidence rate among spouses of people with HIV-1 infection was 38.0 per 1000 person/years [22.5–64.1]. Notably, the HIV-1 incidence rate among HIV-1 seronegative male spouses was 6.7[0.9–47.5] per 1000 person/years, compared to 59.3 [34.4–102.1] per 1000 person/years among female spouses. Sex of the serodiscordant spouse was the only significant variable, even after adjusting for other variables (Hazard rate = 8.86[1.16–67.70], p = 0.036).

Conclusions

Our study suggests that rates of HIV-1 seroconversion of sero-discordant partners are much higher within marriage than in the general population in Tanzania. The major risk factor for HIV-1 seroconversion is sex of the serodiscordant spouse, with female spouses being at very high risk of acquiring HIV infection. This suggests that future programs that target serodiscordant couples could be a novel and effective means of preventing HIV-1 transmission in Tanzania.

Virological Non-suppression and Its Correlates Among Adolescents and Young People Living with HIV in Southern Malawi

We examined virological non-suppression (VLN) among youth ages 13-24 years receiving HIV treatment in public health facilities in six southern Malawi districts. We also tested three ART adherence measures to determine how well each identified VLN: pill counts, a Likert scale item, and a visual analogue scale. VLN was defined as HIV RNA > 1000 copies/ml. Of the 209 youth, 81 (39%) were virally non-suppressed. Male gender and stigma were independently associated with VLN; social support and self-efficacy were independently protective. Pill count had the highest positive predictive value (66.3%). Using a pill count cut-off of < 80% nonadherence, 36 (17%) of the youth were non-adherent. Of the adherent, 120 (69%) were viral suppressed. Results indicate the need to address HIV-related stigma and to bolster social support and selfefficacy in order to enhance viral suppression. In the absence of viral load testing, pill count appears the most accurate means to assess VLN.

Factors associated with viral non-suppression among adolescents living with HIV in Cambodia: a cross-sectional study

BACKGROUND

Adolescents living with HIV on antiretroviral therapy (ART) have worse treatment adherence, viral suppression, and mortality rates compared to adults. This study investigated factors associated with viral non-suppression among adolescents living with HIV in Cambodia.

METHODS

A cross-sectional study was conducted in August 2016 among 328 adolescents living with HIV aged 15-17 years who were randomly selected from 11 ART clinics in the capital city of Phnom Penh and 10 other provinces. Clinical and immunological data, including CD4 count and viral load, were obtained from medical records at ART clinics. Adolescents were categorized as having achieved viral suppression if their latest viral load count was < 1000 ribonucleic acid (RNA) copies/mL. Multivariate logistic regression analysis was performed to identify factors independently associated with viral non-suppression.

RESULTS

The mean age of the participants was 15.9 years (SD = 0.8), and 48.5% were female. Median duration on ART was 8.6 (interquartile range = 6.0-10.6) years. Of total, 76.8% of the participants had achieved viral suppression. After adjustment for other covariates, the likelihood of having viral non-suppression remained significantly lower among adolescents who were: older/aged 17 (AOR = 0.46, 95% CI 0.21-0.98), had been on ART for more than 9 years (AOR = 0.35, 95% CI 0.19-0.64), had most recent CD4 count of > 672 (AOR = 0.47, 95% CI 0.26-0.86), had a relative as the main daily caregiver (AOR = 0.37, 95% CI 0.17-0.80), and did not believe that there is a cure for AIDS (AOR = 0.40, 95% CI 0.21-0.75) compared to their reference group. The likelihood of having viral non-suppression also remained significantly higher among adolescents who had first viral load > 628 RNA copies/mL (AOR = 1.81, 95% CI 1.05-4.08) and among those who were receiving HIV care and treatment from an adult clinic (AOR = 2.95, 95% CI 1.56-5.59).

CONCLUSIONS

The proportion of adolescents living with HIV with viral suppression in this study was relatively high at 76.8%, but falls short of the global target of 90%. Programs targeting younger adolescents and adolescents in transition from pediatric to adult care with a range of interventions including psychosocial support and treatment literacy could further improve viral suppression outcomes.

Social-support needs among adolescents living with HIV in transition from pediatric to adult care in Cambodia: findings from a cross-sectional study

BACKGROUND

Understanding the circumstances of adolescents living with HIV is critical in designing adolescent-friendly services that will facilitate successful transition from pediatric to adult care. This study describes access, utilization and ongoing social support needs among adolescents living with HIV aged 15-17 in transition from pediatric to adult HIV care in Cambodia.

METHODS

A cross-sectional study was conducted among 328 adolescents, randomly selected from 11 antiretroviral therapy (ART) clinics across the country. Descriptive analyses were conducted to summarize their characteristics, access to social support and ongoing support needs among male and female adolescents.

RESULTS

Mean age of the study participants was 15.8 (SD = 0.8) years. Just over half (55.2%) were male. Most had at least one deceased parent (mother 50.9%; father 60.5%), and majority were living with biological parents (40.8%) or relatives (49.3%). A third came from families with an ID poor card, and 21.0% were working for pay. Almost half (46.6%) reported that their family had received social support for their health care, including food support (76.5%), school allowance (62.1%), transport allowance to ART clinics (53.6%), psychosocial counseling (35.3%), vocational training (22.9%) or home visits (11.1%). Several ongoing social support needs were identified, including ongoing inability to cover health expenses unless they are supported by health insurance or health equity fund (55.0%). In addition, adolescents reported having been asked to come back earlier than their scheduled appointment (13.7%), having had to purchase their own drugs (2.7%), experiencing HIV stigma (32.0%), having been denied housing or food due to HIV (8.2%) or failing to attend school within the past month partly because of HIV (16.8%). Two-thirds did not have access to peer support groups.

CONCLUSIONS

Social protection mechanisms are reaching some adolescents in need, while other remain without social support due to discontinuities in health and social care. Multi-sectoral interventions, supporting school attendance, adolescent-friendly clinic scheduling, reductions in child employment, mitigation of HIV-related stigma and strengthening of peer-to-peer support are required to improve coverage of social protection interventions for adolescents in transition.

Routine viral load monitoring in HIV-infected infants and children in low- and middle-income countries: challenges and opportunities

INTRODUCTION

The objective of this commentary is to review considerations for implementing routine viral load (VL) monitoring programmes for HIV-infected infants and children living in low- and middle-income countries (LMIC). Since 2013, the World Health Organization (WHO) guidelines recommend VL testing as the preferred monitoring approach for all individuals treated with ART in order to assess treatment response, detect treatment failure and determine the need to switch to a second-line regimen in a timely manner. More recently, WHO guidelines from 2016 identify HIV-infected infants and children as a priority group for routine VL monitoring.

DISCUSSION

There are a number of reasons why HIV-infected infants and children should be prioritized for routine VL monitoring. Data from national VL monitoring programmes as well as systematic reviews and meta-analyses from LMIC indicate rates of viral suppression are lower for infants and children compared to adults. The number of antiretroviral drugs and palatable formulations suitable for young children are limited. In addition, emotional and developmental issues particular to children can make daily medication administration difficult and pose a challenge to adherence and achievement of sustained viral suppression. VL monitoring can be instrumental for identifying those in need of additional adherence support, reducing regimen switches and preserving treatment options. The needs of infants and children warrant consideration in all aspects of VL monitoring services. If capacity for paediatric venipuncture is not assured, platforms that accept dried blood spot specimens are necessary in order for infants and children to have equitable access. Healthcare systems also need to prepare to manage the substantial number of infants and children identified with elevated VL, including adherence interventions that are appropriate for children. Establishing robust systems to evaluate processes and outcomes of routine VL monitoring services and to support drug forecasting and supply management is essential to determine best practices for infants and children in LMIC.

CONCLUSIONS

The particular concerns of HIV-infected infants and children warrant attention during all phases of planning and implementation of VL monitoring services. There are a number of key areas, including frequency of monitoring, blood specimen type and adherence challenges, where specific approaches tailored for infants and children may be required.

Immuno-virological response and associated factors amongst HIV-1 vertically infected adolescents in Yaoundé-Cameroon

Introduction

Limited studies have reported the outcomes of lifelong antiretroviral therapy (ART) amongst adolescents living with HIV (ALWHIV) in resource-limited settings (RLS), thus classifying this population as underserved. We therefore aimed to ascertain the immunological and virological responses, and associated factors amongst Cameroonian ALWHIV.

Method

A cross-sectional and observational study was conducted from January through May 2016 at the National Social Insurance Fund Health Centre in Yaoundé-Cameroon. Immunological and virological responses were evaluated using CD4 cell count and viral load respectively, with viral suppression (VS) defined as <50 copies/ml. Adherence was evaluated using self-reported missing doses during the past 14 days. Data were analyzed using R v.3.3.0, with p<0.05 considered statistically significant.

Results

Of the 145 ALWHIV on ART enrolled in the study, 52% were female, median age [interquartile (IQR)] was 13 [11–16] years, median [IQR] time-on-ART was 7 [5–10] years, 48% were orphans, 92% were on first-line ART and 36% were adherent to ART. Following ART response, 79% (114/145) had CD4 ≥500/mm³, 71.0% (103/145) were on VS of whom 52.4% (76/145) had a sustained VS. Duration of ART was associated with immune restoration (Odd Ratio 3.73 [1.26–12.21]) but not with virological response. Risks of poor adherence were greater in orphans of both parents (p = 0.078).

Conclusion

In this urban setting of Cameroon, ALWHIV receiving ART show favorable immunological and virological response in a medium run. For long-term ART success, implementing a close monitoring of adherence and risks of viral rebound would be highly relevant, especially for orphans of both parents.

Adolescents with HIV and transition to adult care in the Caribbean, Central America and South America, Eastern Europe and Asia and Pacific regions

INTRODUCTION

The HIV epidemics in the Caribbean, Central America and South America (CCASA), Eastern Europe (EE) and Asia and Pacific (AP) regions are diverse epidemics affecting different key populations in predominantly middle-income countries. This narrative review describes the populations of HIV-positive youth approaching adolescence and adulthood in CCASA, EE and AP, what is known of their outcomes in paediatric and adult care to date, ongoing research efforts and future research priorities.

METHODS

We searched PubMed and abstracts from recent conferences and workshops using keywords including HIV, transition and adolescents, to identify published data on transition outcomes in CCASA, EE and AP. We also searched within our regional clinical/research networks for work conducted in this area and presented at local or national meetings. To give insight into future research priorities, we describe published data on characteristics and health status of young people as they approach age of transition, as a key determinant of health in early adulthood, and information available on current transition processes.

RESULTS AND DISCUSSION

The perinatally HIV-infected populations in these three regions face a range of challenges including parental death and loss of family support; HIV-related stigma and socio-economic disparities; exposure to maternal injecting drug use; and late disclosure of HIV status. Behaviourally HIV-infected youth often belong to marginalized sub-groups, with particular challenges accessing services and care. Differences between and within countries in characteristics of HIV-positive youth and models of care need to be considered in comparisons of outcomes in young adulthood. The very little data published to date on transition outcomes across these three regions highlight some emerging issues around adherence, virological failure and loss to follow-up, alongside examples of programmes which have successfully supported adolescents to remain engaged with services and virologically suppressed.

CONCLUSIONS

Limited data available indicate uneven outcomes in paediatric services and some shared challenges for adolescent transition including retention in care and adherence. The impact of issues specific to low prevalence, concentrated epidemic settings are poorly understood to date. Outcome data are urgently needed to guide management strategies and advocate for service provision in these regions.

Transition into adult care: factors associated with level of preparedness among adolescents living with HIV in Cambodia

Background

Preparing adolescents for transition into adult care and supporting their acquisition of self-health care management skills is a critical determinant of their post-transition HIV care outcomes. However, there is a scarcity of research on effective transition strategies. This study explores factors associated with adolescent preparedness for transition into adult care in Cambodia.

Methods

In August 2016, a cross-sectional study was conducted among 223 adolescents living with HIV aged 15–17, randomly selected from 11 antiretroviral therapy clinics, utilizing a structured questionnaire. The level of preparedness was determined using a pre-existing scale, and adolescents were categorized as having a high- or low level of preparedness for transition. Bivariate and multivariate analyses were conducted.

Results

Of 223 adolescents, 55.2% were male, and their mean age was 15.8 years. Overall, 53.3% had a high level of preparedness for transition. As part of the transition protocol, 2.7% had completed a transfer form, 24.7% had a transition case manager, 29.6% had been counselled about the transition, and 19.7% had visited an adult ART clinic. In multivariate analysis, a higher level of preparedness for transition was independently associated with older age (AOR 2.44, 95% CI 1.34–4.46; p = 0.004), family having received social support for their health (AOR 5.32, 95% CI 1.97–14.36; p = 0.001), knowing the kind of treatment they received (ART) (AOR 12.67, 95% CI 2.91–15.19; p = 0.001), trust in friends or family for HIV treatment (AOR 7.82, 95% CI 1.13–8.89; p = 0.008), receiving counseling on transition (AOR 3.17, 95% CI 1.15–8.76; p = 0.03), having a ‘Case Manager’ identified to support them during the preparation process for transition (AOR 3.89, 95% CI 1.08–13.96; p = 0.04), and satisfaction with preparation process for transition in general (AOR 0.35, 95% CI 0.03–0.87; p = 0.01).

Conclusions

A range of individual, social and health system and services factors may determine successful transition preparedness among adolescents in Cambodia. Strengthening implementation of age-appropriate and individualized case management transition at all sites, while creating supportive family, peer, and healthcare environments for adolescent transition is required.

Influence of the informal primary caretaker on glycemic control among prepubertal pediatric patients with type 1 diabetes mellitus

OBJECTIVES

In prepubertal type 1 diabetic patients (DM1), the availability of an informal primary caregiver (ICP) is critical to making management decisions; in this study, the ICP-related risk factors associated with glycemic control were identified.

PATIENTS, MATERIALS, AND METHODS

A comparative cross-sectional study was performed. Fifty-five patients with DM1 under the age of 11 years were included. The patient-related factors associated with glycemic control evaluated were physical activity, DM1 time of evolution, and adherence to medical indications. The ICP-related factors evaluated were education, employment aspects, depressive traits (Beck questionnaire), family functionality (family APGAR), support of another person in patient care, stress (Perceived Stress Scale), and socioeconomic status (Bronfman questionnaire). Multivariate logistic and linear regression analyses were performed.

RESULTS

The patients' median age was 8 years; 29 patients had good glycemic control, and 26 were uncontrolled. The main risk factor associated with glycemic dyscontrol was stress in the ICP (OR 24.8; 95% CI 4.06-151.9, p=0.001). While, according to the linear regression analysis it was found that lower level of education (β 0.991, 95% CI 0.238-1.743, p=0.011) and stress (β 1.918, 95% CI 1.10-2.736, p=0.001) in the ICP, as well as family dysfunction (β 1.256, 95% CI 0.336-2.177, p=0.008) were associated with higher levels of glycated hemoglobin.

CONCLUSIONS

Level of education and stress in the ICP, as well as family dysfunction, are factors that influence the lack of controlled blood glucose levels among prepubertal DM1 patients.

Survival Estimates and Mortality Risk Factors in a Cohort of HIV Vertically Infected Individuals in Salvador, Brazil

BACKGROUND

There are few data on long-term survival of Brazilian children with vertically acquired HIV infection. We assessed survival, mortality risk factors and response to antiretroviral therapy (ART). We compared children with early and late access to care.

METHODS

We used Kaplan-Meier survival curves with Log-rank tests to compare survival time and mortality rates of 245 HIV vertically infected children admitted for care during 2002-2014.

RESULTS

Total follow-up sum was 1584.4 person-years. Overall survival was 83.9%. Median age at start of ART was 51.6 (18.0-94.2) months, and median age at death was 8.2 (1.7-10.1) years (mortality rate: 1.7/100 person-years). Pneumonia and sepsis were the main causes of death. Male gender, viral load (VL) ≥100,000 copies, severe immunosuppression, moderate/severe symptoms and history of opportunistic infection were associated with higher mortality in bivariate analysis. Only severe symptoms remained associated in multivariate analysis (P = 0.03). There was no difference in mortality in early compared to late access group. Overall, 217 patients received ART; 192 had a recent VL, of which 116 (59.8%) had ≤400 copies. Variables associated with therapeutic failure were as follows: VL ≥100,000 copies, less immune suppression, age <12 months at admission and age <3 years at ART start.

CONCLUSIONS

We have a high mortality rate in comparison with developed countries. Although early access did not impact mortality, we detected a trend in favor of early treatment as a protecting factor against mortality. We need to increase adherence to care and treatment, and better drugs to optimize outcomes.

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.

Children and Adolescents with Perinatal HIV-1 Infection: Factors Associated with Adherence to Treatment in the Brazilian Context

Challenges to the adherence to combination antiretroviral therapy among the pediatric population should be understood in the context of the trajectories of families, their interaction with healthcare services, and their access to material and symbolic goods. The present study analyzed individual, institutional and social factors that might be associated with the caregivers’ role in the treatment adherence of children and adolescents living with HIV (CALHIV). Based on semi-structured interviews and questionnaires applied to 69 caregivers seen at pediatric AIDS services of five Brazilian macro-regions, we observed that adherent caregivers had better acceptance of diagnosis and treatment, were less likely to face discrimination and social isolation secondary to AIDS-related stigma and tended to believe in the efficacy of treatment, and to be more optimistic about life perspectives of CALHIV. Interventions aiming to improve adherence and to promote the health of CALHIV should take in consideration the interplay of such different factors.

Viral suppression in adolescents on antiretroviral treatment: review of the literature and critical appraisal of methodological challenges

Objective

Medication adherence is often suboptimal for adolescents with HIV, and establishing correct weight‐based antiretroviral therapy dosing is difficult, contributing to virological failure. This review aimed to determine the proportion of adolescents achieving virological suppression after initiating ART.

Methods

MEDLINE, EMBASE and Web of Science databases were searched. Studies published between January 2004 and September 2014 including ≥50 adolescents taking ART and reporting on the proportion of virological suppressed participants were included.

Results

From a total of 5316 potentially relevant citations, 20 studies were included. Only eight studies reported the proportion of adolescents that were virologically suppressed at a specified time point. The proportion of adolescents with virological suppression at 12 months ranged from 27 to 89%.

Conclusion

Adolescent achievement of HIV virological suppression was highly variable. Improved reporting of virological outcomes from a wider range of settings is required to support efforts to improve HIV care and treatment for adolescents.

Evaluation of factors associated with vertical HIV-1 transmission

OBJECTIVE

To compare the prevalence and factors associated with vertical transmission of human immunodeficiency virus 1 (HIV-1) among pregnant women treated in the periods of 1998-2004 and 2005-2011 in a reference service for the care of HIV-infected patients in southern Brazil.

METHODS

This was a descriptive and analytical study that used the databases of laboratories from the CD4 and STDs/AIDS Viral Load National Laboratory Network of the Brazilian Ministry of Health. HIV-1-infected pregnant women were selected after an active search for clinical information and obstetric and neonatal data from their medical records between the years of 1998 and 2011.

RESULTS

102 pregnant women were analyzed between 1998 and 2004 and 251 in the period between 2005 and 2011, totaling 353 children born to pregnant women with HIV-1. It was observed that the vertical transmission rate was 11.8% between 1998 and 2004 and 3.2% between 2005 and 2011 (p<0.001). The increased use of antiretroviral drugs (p=0.02), the decrease in viral load (p<0.001), and time of membrane rupture lower than 4h (p<0.001) were associated with the decrease of vertical transmission factors when comparing the two periods.

CONCLUSION

It was observed a decrease in the rate of vertical transmission in recent years. According to the studied variables, is suggested that the risk factors for vertical transmission of HIV-1 were absence of antiretroviral therapy, high viral load in the pregnant women, and membrane rupture time >4h.

Perinatally infected adolescents living with human immunodeficiency virus (perinatally human immunodeficiency virus)

The availability of highly potent antiretroviral treatment during the last decades has transformed human immunodeficiency virus (HIV) infection into a chronic disease. Children that were diagnosed during the first months or years of life and received treatment, are living longer and better and are presently reaching adolescence and adulthood. Perinatally HIV-infected adolescents (PHIV) and young adults may present specific clinical, behavior and social characteristics and demands. We have performed a literature review about different aspects that have to be considered in the care and follow-up of PHIV. The search included papers in the MEDLINE database via PubMed, located using the keywords “perinatally HIV-infected” AND “adolescents”. Only articles published in English or Portuguese from 2003 to 2014 were selected. The types of articles included original research, systematic reviews, and quantitative or qualitative studies; case reports and case series were excluded. Results are presented in the following topics: “Puberal development and sexual maturation”, “Growth in weight and height”, “Bone metabolism during adolescence”, “Metabolic complications”, “Brain development, cognition and mental health”, “Reproductive health”, “Viral drug resistance” and “Transition to adult outpatient care”. We hope that this review will support the work of pediatricians, clinicians and infectious diseases specialists that are receiving these subjects to continue treatment.
