Vulnerability, Human Rights, and Comprehensive Health Care Needs of Young People Living With HIV/AIDS

We sought to identify and understand the health care needs of young people living with HIV/AIDS, particularly in terms of their psychosocial well-being. We conducted a qualitative analysis of HIV-positive young people and their caregivers, focusing on the implications of an HIV diagnosis for health care needs. Stigma was a recurrent issue that arose in the interviews conducted with the respondents, and it was evident that youths had been denied many rights related to health. We concluded that young people living with HIV need comprehensive care based on a human rights approach. In this regard, we offer some practical recommendations for health programs.

Improving survival among Brazilian children with perinatally-acquired AIDS

UNLABELLED Brazil was the first developing country to provide free, universal access to antiretroviral treatment for AIDS patients. The Brazilian experience thus provides the first evidence regarding the impact of such treatment on the survival of perinatally acquired AIDS cases in the developing world. MATERIAL AND METHODS This retrospective cohort study used medical record reviews to examine characteristics and trends in the survival of a representative sample of 914 perinatally acquired AIDS cases in 10 Brazilian cities diagnosed between 1983 and 1998. RESULTS Survival time increased steadily and substantially. Whereas half of the children died within 20 months of diagnosis at the beginning of the epidemic, 75% of children diagnosed in 1997 and 1998 were still alive after four years of follow-up. CONCLUSIONS Advances in management and treatment have made a great difference in the survival of Brazilian children with AIDS. These results argue strongly for making such treatment available to children in the entire developing world.

AIDS by mother-to-child transmission: Survival analysis of cases followed from 1983 to 2002 in different regions of Brazil.

Antiretroviral therapy contributes to decreasing morbidity and mortality, and ultimately to increasing survival. In Brazil, there are regional differences in HIV epidemiology regarding pregnant women and children with HIV/AIDS. This study evaluates survival time after AIDS diagnosis in 914 children infected by mother-to-child transmission, reported between 1983 and 1998 and followed until 2002, in Brazils five regions. Time between birth and HIV diagnosis decreased over the years, mainly in the South and Southeast Regions. There was a significant improvement in survival; more than 75% of cases were still living four years after diagnosis in the 1997-1998 group. This Brazilian study demonstrates that even with regional inequalities in health care infrastructure it is possible for a developing country to establish an effective system of universal and free access to antiretroviral therapy that produces a significant increase in survival for children with AIDS.

A sexualidade de adolescentes vivendo com HIV: direitos e desafios para o cuidado

Sexuality and reproductive healthcare represent relevant issues for comprehensive care of HIV-positive adolescents. However, public policies and health services give this issue insufficient attention. The scope of this article is to assess how HIV-positive young people and teenagers cope with their sexuality, dating and the urge to have children and start a family. In a qualitative study, in-depth interviews were staged with 21 HIV-positive (contracted by vertical, sexual or intravenous transmission) teenagers and 13 caregivers of children and youths living in Sao Paulo and Santos. The interviews revealed the different ways teenagers cope with their sexuality and with the anxiety of HIV disclosure in this context. Lack of information about HIV prevention, lack of support and skills to cope with their sexuality were revealed in the reports. Furthermore, stigma and discrimination were the most frequently reported difficulties. The main challenges to be faced in Brazil in regard to this issue are discussed, especially the need to consider HIV-positive youth as entitled to sexual rights. Recommendations are also made for incorporating the issue into a humanized and comprehensive care approach for HIV-positive children and young people.

A randomized study of tenofovir disoproxil fumarate in treatment-experienced HIV-1 infected adolescents.

Background: There are few data on the safety and antiviral activity of tenofovir disoproxil fumarate (TDF) in HIV-1 infected adolescents. Methods: A randomized, double-blinded, placebo-controlled study was conducted. Ninety adolescents (12 to <18 years) who were viremic while receiving antiretroviral treatment were randomized to receive TDF 300 mg (mean, 216.8 mg/m2) or placebo in combination with an optimized background regimen (OBR) for 48 weeks. The primary efficacy endpoint was time-weighted average change in plasma HIV-1 RNA from baseline at week 24 Results: Eighty-seven subjects (45 TDF, 42 placebo) received the study drug. Through week 24, the median time-weighted average change in plasma HIV-1 RNA was not different between the TDF and placebo groups (−1.6 versus −1.6 log10copies/mL, P = 0.55). The percentages of subjects who achieved HIV-1 RNA <400 copies/mL were similar at week 24 (40.9 versus 41.5%). One fourth of subjects in the TDF and placebo groups (24.4 versus 28.6%) had at least 3 active agents in the OBR. Many subjects in both groups had baseline genotypic resistance to TDF (48.9 versus 33.3%). TDF was generally safe and well tolerated. There were no statistically significant differences in changes of renal function and bone mineral density between the 2 groups. Conclusion: This study of TDF in combination with an OBR in antiretroviral-experienced adolescents did not meet its primary or secondary efficacy endpoints. The effectiveness of the OBR and baseline genotypic resistance to TDF in both groups may have confounded the efficacy findings. No clinically relevant TDF-related renal or bone toxicities were observed in this adolescent population.

Improving survival in children with AIDS in Brazil: results of the second national study, 1999-2002

The objective of this study is to characterize survival in children with AIDS diagnosed in Brazil between 1999-2002, compared with the first national study (1983-1998). This national retrospective cohort study examined a representative sample of Brazilian children exposed to HIV from mother-to-child transmission and followed through 2007. The survival probability after 60 months was analyzed by sex, year of birth and death, clinical classification, use of antiretroviral therapy (ART) and prophylaxis for opportunistic diseases. 920 children were included. The survival probability increased: comparing cases diagnosed before 1988 with those diagnosed from 2001-2002 it increased by 3.5-fold (from 25% to 86.3%). Use of ART, initial clinical classification, and final classification were significant (p < 0.001) predictors of survival. Issues regarding quality of records and care were identified. The results point to the success of the Brazilian policy of providing ART. The improvement of clinical status contributes to quality of life, while indicating challenges, particularly practices to improve long-term care.

Viral Load Predicts New World Health Organization Stage 3 and 4 Events in HIV-Infected Children Receiving Highly Active Antiretroviral Therapy, Independent of CD4 T Lymphocyte Value

BACKGROUND Many resource-limited countries rely on clinical and immunological monitoring without routine virological monitoring for human immunodeficiency virus (HIV)-infected children receiving highly active antiretroviral therapy (HAART). We assessed whether HIV load had independent predictive value in the presence of immunological and clinical data for the occurrence of new World Health Organization (WHO) stage 3 or 4 events (hereafter, WHO events) among HIV-infected children receiving HAART in Latin America. METHODS The NISDI (Eunice Kennedy Shriver National Institute of Child Health and Human Development International Site Development Initiative) Pediatric Protocol is an observational cohort study designed to describe HIV-related outcomes among infected children. Eligibility criteria for this analysis included perinatal infection, age <15 years, and continuous HAART for ≥6 months. Cox proportional hazards modeling was used to assess time to new WHO events as a function of immunological status, viral load, hemoglobin level, and potential confounding variables; laboratory tests repeated during the study were treated as time-varying predictors. RESULTS The mean duration of follow-up was 2.5 years; new WHO events occurred in 92 (15.8%) of 584 children. In proportional hazards modeling, most recent viral load >5000 copies/mL was associated with a nearly doubled risk of developing a WHO event (adjusted hazard ratio, 1.81; 95% confidence interval, 1.05-3.11; P = .033), even after adjustment for immunological status defined on the basis of CD4 T lymphocyte value, hemoglobin level, age, and body mass index. CONCLUSIONS Routine virological monitoring using the WHO virological failure threshold of 5000 copies/mL adds independent predictive value to immunological and clinical assessments for identification of children receiving HAART who are at risk for significant HIV-related illness. To provide optimal care, periodic virological monitoring should be considered for all settings that provide HAART to children.

Dyslipidemia in a Cohort of HIV-infected Latin American Children Receiving Highly Active Antiretroviral Therapy

In order to describe the prevalence of hypercholesterolemia and hypertriglyceridemia in a cohort of HIV-infected children and adolescents in Latin America and to determine associations with highly active antiretroviral therapy (HAART), we performed this cross-sectional analysis within the NICHD International Site Development Initiative pediatric cohort study. Eligible children had to be at least 2 years of age and be on HAART. Among the 477 eligible HIV-infected youth, 98 (20.5%) had hypercholesterolemia and 140 (29.4%) had hypertriglyceridemia. In multivariable analyses, children receiving protease inhibitor (PI)-containing HAART were at increased risk for hypercholesterolemia [adjusted odds ratio (AOR) =  2.7, 95% confidence interval (CI) 1.3-5.6] and hypertriglyceridemia (AOR = 3.5, 95% CI 1.9-6.4) compared with children receiving non-nucleoside reverse transcriptase inhibitor (NNRTI)-containing HAART. In conclusion, HIV-infected youth receiving PI-containing HAART in this Latin American cohort were at increased risk for hypercholesterolemia and hypertriglyceridemia compared with those receiving NNRTI-containing HAART.

Lipid levels in the second year of life among HIV-infected and HIV-exposed uninfected Latin American children

Background:Dyslipidemia is observed among older children and adults with HIV. We examined nonfasting cholesterol and triglycerides in two groups of 12–23-month-old Latin American children – HIV-infected vs. HIV-exposed but uninfected (HEU). Methods:HIV-infected and HEU children in Latin America and Jamaica were enrolled in an observational cohort. Eligibility for this analysis required having cholesterol and triglyceride results available during the second year of life. Results:HIV-infected (n = 83) children were slightly older at the time of lipid testing than the HEU (n = 681). Forty percent of the HIV-infected children were on protease inhibitor-based antiretroviral therapy (ART); 41% were not on ART. There was no statistically significant difference in mean cholesterol concentrations (mg/dl) by HIV status; however, the HIV-infected children had higher mean triglyceride concentrations. The prevalence of high cholesterol (>200 mg/dl) and high triglycerides (>110 mg/dl) was higher among the HIV-infected vs. HEU. Among the HIV-infected children, mean cholesterol and triglyceride concentrations varied by ART. Children receiving no ART had a significantly lower mean cholesterol concentration. Those receiving protease inhibitor-containing ART had a significantly higher mean triglyceride concentration compared to the other two antiretroviral regimen groups. Conclusion:A greater proportion of HIV-infected children at 12–23 months have hyperlipidemia when compared to HEU children, with the highest triglyceride concentrations observed among those receiving protease inhibitor-containing ART, and the lowest cholesterol levels among those not receiving ART. Implications of these findings will require continued follow-up of HIV-infected children who initiate therapy early in life.

Costs and benefits of secrecy: the dilemma experienced by adolescents seropositive for HIV

ABSTRACT This study explored the experiences of the first generation of adolescents who acquired HIV through vertical transmission when disclosing their diagnosis to friends and romantic partners. The study sample was selected by convenience, with 20 patients (13–20 years old) participating in a qualitative investigation using individual interviews (language: Portuguese; duration: 45 minutes). The participants were followed in specialized clinics for the treatment of pediatric AIDS in São Paulo, Brazil. The results suggest that families who live with HIV tend to keep it a secret, and such behavior is learned and accepted unquestioningly as natural. Respect for privacy and the fear of rejection, coupled with the belief that information about their disease will be spread, are the main beliefs with which participants justify their secrecy. In terms of romantic relationships, adolescents were aware that their HIV status should at some point be shared with current or future sexual partners. However, the decision to reveal an HIV diagnosis in romantic relationships is permeated by anxieties, uncertainties about the right time, and fear of abandonment. In any case, telling the truth requires trust, guarantees of the other’s love, and, in some cases, probing romantic partners beforehand to learn their perceptions about the disease. Participants who had experiences disclosing their HIV status shared positive and negative results, including emotional support, acceptance, and understanding, along with ostracism, discrimination, and abandonment by family members. The findings of this paper reinforce the challenges of revealing an HIV diagnosis to third parties. It requires understanding the meaning and importance of the secret for each patient, along with the conflict between the right to confidentiality and the responsibility of treating others exposed to the disease. All these aspects should be discussed extensively with this population and incorporated into clinical practice.
