A profile of human immunodeficiency virus-infected adolescents receiving health care services at selected sites in the United States

Characteristics of HIV infected adolescents in Latin America: results from the NISDI pediatric study

OBJECTIVE

HIV-infected adolescents are a heterogeneous population; source of infection, immunodeficiency severity and antiretroviral (ARV) experience vary. Here, we describe youth followed in an observational study at Latin American sites of the NICHD International Site Development Initiative (NISDI).

METHODS

The NISDI pediatric protocol is an ongoing prospective cohort study that collects demographic, clinical, immunologic, virologic and medication data. Youth were enrolled at 15 sites in Brazil, Argentina and Mexico between 2002 and 2006. HIV-infected subjects aged 12-21 years at the time of enrollment were analyzed.

RESULTS

Data from 120 HIV-infected youth were analyzed. Sixty-nine (58%) had acquired HIV through vertical transmission (VT); 51(42%) via horizontal transmission (HT). Twenty-eight percent of the VT group were not diagnosed until they were ≥10 years of age. Ninety-one percent of the VT group and 46% of the HT were receiving ARV at enrollment. Modes of HT included sexual (ST), blood product transfusion (BPT) and unknown (U). Severe immunodeficiency was frequent (21%) in the ST group. Low BMI was frequent in the VT and BPT sub-groups. Utilization of HAART increased over the course of the study, but viral suppression was present in only 38% of the VT group and 37% of the HT group at study end.

CONCLUSIONS

This cohort of HIV-infected adolescents in Latin America displayed a diverse epidemiologic pattern. Care providers must be prepared to address the diverse needs and challenges of this population. The levels of virologic suppression achieved were inadequate. Further research into appropriate interventions for this population is urgently needed.

Adolescents and HIV: prevention and clinical care

The incidence of HIV infection has increased to alarming proportions among minority youth, in particular among young men who have sex with men and among teenage girls. The unique socioeconomic, behavioral, and emotional vulnerability of adolescents for sexually transmitted diseases, including HIV, requires early identification of HIV infection for linkage to care. Differences in the clinical and psychosocial presentations of youth with perinatally versus behavioral acquired HIV infection are important and influence the acceptance of illness, self-efficacy, and antiretroviral treatment adherence. The ideal multidisciplinary team approach of culturally sensitive services for youth integrates clinical care, psychosocial and peer support interventions, transition planning, primary and secondary prevention, as well as comprehensive reproductive adolescent health services.

Differences among sexually abused and nonabused youth living with HIV

Risk behaviors were compared between sexually abused and nonabused youth living with HIV (YLH). Abused YLH were significantly more likely to have attempted suicide, to have been admitted into an alcohol and/or drug treatment program, and to have engaged in crack cocaine use than were nonabused YLH and had a greater number of sexual partners. A significantly higher proportion of abused YLH had been incarcerated in contrast to nonabused youth. There were also significantly greater conduct problems among abused YLH. Finally, abused YLH had significantly higher scores on positive action and social-support coping styles than nonabused youth. Consistent with previous research, abused youth are at higher risk for a variety of negative outcomes and are also similar in many respects to sexually abused youth who are not HIV-positive. The high frequencies of two positive styles of coping among abused YLH were also observed.

Risk behaviors of youth living with HIV: pre- and post-HAART

OBJECTIVE

To examine the transmission behavior among youth living with HIV (YLH), pre- and post-HAART.

METHODS

Two cohorts were recruited: (1) 349 YLH during 1994 to 1996 and (2) 175 YLH during 1999 to 2000, after the wide availability of HAART. Differences in sexual and substance-use risk acts and quality of life were examined.

RESULTS

Post-HAART YLH were more likely to engage in unprotected sex and substance use, to be more emotionally distressed, and to have lower quality of life than were pre-HAART YLH.

CONCLUSIONS

Targeted interventions for YLH that address reductions in transmission acts and aim to improve quality of life are still needed.

Boston HAPPENS Program: HIV-positive, homeless, and at-risk youth can access care through youth-oriented HIV services

The Boston HAPPENS Program is a collaborative network of care consisting of multiservice outreach agencies; community health centers; and hospitals for HIV-positive, homeless, and hard-to-reach youth. In four years of data collection, the program served more than 2,000 youth, including 54 HIV-positive youth. The youth were 19.9 +/- 2.9 years old; 64 percent female; 45 percent youth of color; 11 percent gay/lesbian, bisexual, or undecided; and 13 percent homeless or runaway. Homeless youth were much more likely to have been involved with a mental health system (47% vs. 12%, P < 0.001), the criminal justice system (20% vs. 2%, P < 0.001), high-risk sexual behaviors (21% vs. 3%, P < 0.001), and substance abuse (25% vs. 6%, P < 0.001) than were other youth served by the program. Comprehensive networks of care offering a continuum of services and a variety of entry routes and types of care sites are needed to connect under-served youth to health care. Outreach and human immunodeficiency virus (HIV) counseling and testing services can offer important portals of entry into health services for at-risk youth. Support services such as outreach, case management, and mental health services are needed to complement medical services by all youth at-risk for contracting HIV. Support services are necessary for the initiation and retention of youth in care so that early case identification and complex treatment regimens can be initiated and tailored to the individual.

Initiation of services in the Boston HAPPENS Program: human immunodeficiency virus-positive, homeless, and at-risk youth can access services

This study evaluates the factors associated with initiation of services in the Boston HAPPENS Program, which is a collaborative network of care consisting of multiservice outreach agencies, community health centers and hospitals, for human immunodeficiency virus (HIV)-positive and hard to reach youth who are 12-24 years old. The program served 2116 youth who were 19.8 +/- 2.9 years old; 64% female; 45% youth of color; 16% gay/lesbian, bisexual, or undecided; and 10% homeless or runaway. At first contact with the program, 56% received outreach services; and 91% received a health intervention. Among those receiving a health intervention, 55% had HIV counseling and testing services, 49% medical care, 24% case management, and 9% mental health services. HIV-positive youth needed more contacts before a first medical visit than those who were HIV-negative or untested (p < 0.001). Different kinds of service sites reached different populations of at-risk youth. Logistic regression modeling showed that for young women, older age, lesbian-bisexual orientation, substance use, high-risk sexual behaviours, and receiving outreach services at first contact were independent predictors of initiation of services at outreach agencies; however, unprotected sex with males, and pregnancy were associated with a greater likelihood of care at hospitals or community health centers. For young men, older age, Asian/other ethnicity, and substance abuse were associated with care at outreach agencies; however, positive HIV status and unprotected sex with females were associated with care at hospitals or community health centers. Comprehensive networks of care offering a continuum of services and a variety of entry routes and types of care sites are needed to connect underserved youth to health care.

Health and risk behaviors over time among youth living with HIV

Health practices and transmission behaviors were examined over time among 25 disabled youth living with HIV (YLH) living in a comprehensive residential care program. YLH were aged 19-24 years (M=23.4 years); 89 per cent of males were gay, bisexual, or transgendered (60% Caucasian); all had physical and mental health problems, as well as substance abuse disorders. YLH were assessed at least four times at 3-month intervals and reported high lifetime rates of sexual and substance-use risk acts. Over four assessments, YLH improved their nutrition and hygiene and decreased their worry about their health status. YLH evidenced no decrease in the frequency of substance use and sexual risk. Depression, self-esteem, and health status also were stable over time. YLH who have a lifetime history of multiple problem behaviors are likely to change slowly over time, even when receiving comprehensive residential care.

Linking HIV-seropositive youth with health care: evaluation of an intervention

The purpose of this study was to evaluate the use of a statewide human immunodeficiency virus (HIV) surveillance system to link infected adolescents with care. Eligible participants were HIV-seropositive youths who were reported to the Department of Health from 1985 to 1998 in a state with mandatory, name-linked reporting of HIV and acquired immunodeficiency syndrome (AIDS) cases. Standard public health disease surveillance and intervention strategies were used to link participants with HIV/AIDS case management services. Enrollment in case management services was assessed before and after the intervention was implemented in 1993. The proportion of participants receiving case management services increased from 33% to 51% (p = 0.058) after the intervention was implemented. Although enrollment in case management did not vary significantly with participants' demographic and transmission characteristics, people of color were less likely than Caucasians to be located and interviewed. In conclusion, the system of name linked reporting of HIV/AIDS cases was used successfully to increase case management by 55% above baseline levels.

Effective detection of HIV

Biomedical advances, new HIV testing technologies, and policy shifts in the last 15 years have created substantial new challenges and opportunities for service providers, policy makers, and researchers regarding broad scale identification of HIV-seropositive persons. Effective HIV testing will be achieved when we: (1) increase the number of high-risk persons tested; (2) decrease the time from HIV infection to detection; (3) increase testing acceptability; (4) increase the proportion of individuals tested who receive their results; and (5) increase the proportion of individuals tested seropositive who are linked to care. Strategies to enhance effectiveness include implementing new testing technologies and delivery modalities; expanding access to client-controlled testing; targeting providers' knowledge, attitudes, and behaviors regarding HIV testing; mainstreaming HIV testing as routine clinical care; targeting persons who engage in high-risk behaviors and those in high-risk groups; and implementing a national behavioral surveillance system. Addressing these challenges will improve HIV detection in the United States, which is vital to both HIV prevention and treatment.

Psychological distress among HIV(+) adolescents in the REACH study: effects of life stress, social support, and coping. The Adolescent Medicine HIV/AIDS Research Network

PURPOSE

To investigate the effects of life events, social support, and coping on anxiety and depression among human immunodeficiency virus (HIV)-infected adolescents. It was hypothesized that higher levels of stressful events would be associated with higher levels of anxiety and depression, but that this association would be moderated by satisfaction with social support and by adaptive coping.

METHODS

HIV-infected adolescents from 16 locations in 13 U.S. cities (N = 230, median age 16.09 years, standard deviation 1.2, range 13-19; 77% females) were recruited into the Reaching for Excellence in Adolescent Care and Health (REACH) project. REACH is the first large-scale disease progression study of HIV(+) adolescents infected through sexual behavior or injection drug use. The adolescent assessment was conducted by audio-computer assisted self-interview. Least squares regressions were used to test hypotheses.

RESULTS

Life events with high impact were associated with higher levels of depression and anxiety. Frequently reported events included: being prescribed medications (74%), family financial problems (61%), and parental alcohol abuse (20%). Contrary to expectations, the buffering hypotheses of social support and adaptive coping were not supported. Satisfaction with social support and adaptive coping methods were both associated directly with lower levels of depression, but no association was detected between these two measures and anxiety.

CONCLUSIONS

Although life event distress was directly associated with psychological distress, neither social support nor adaptive coping seemed to moderate this association. However, both satisfaction with support and adaptive coping were associated directly with depression in HIV-infected adolescents.

Serologic examination of hepatitis B infection and immunization in HIV-positive youth and associated risks. The Pediatric AIDS Clinical Trials Group Protocol 220 Team

This seroprevalence report examines serologic evidence of hepatitis B immunization or infection and associated demographic/behavioral factors in adolescent (aged 12-20) subjects enrolled in a nontherapeutic clinical trial at 43 Pediatric AIDS Clinical Trials Group (PACTG) clinical centers. Subjects (n = 94) infected with the human immunodeficiency virus (HIV) through sexual activity were categorized as hepatitis B virus (HBV)-immunized, HBV-infected, or nonimmune by hepatitis B serology performed on specimens collected within the subject's first 48 weeks on study (1993-1995). Sixteen percent of the 94 serologically classified subjects were immunized; 19% HBV-infected; 65% nonimmune. Of the three risk factor scores examined (sociodemographic, sexual, and substance abuse), substance use alone demonstrated a significant difference among groups (despite virtually no reported injecting drug behavior), with the sexual risk score exhibiting marginally significant differences. Logistic regression analysis (restricted to nonimmunized subjects) showed that male-male sexual activity raised the odds of HBV infection by a factor of 5.14 (95% confidence interval [CI]: 1.45-18. 23) relative to heterosexual activity; and that for every one point increase on the substance abuse risk scale the odds of infection increased 5% (95% CI: 0.99-1.10). The HBV infection rate in PACTG 220 HIV-positive females is twice United States population-based rates; the rate in PACTG 220 HIV-positive males is nearly seven times higher. Past immunization efforts in this population appear to have been based on sexual activity volume without regard to injecting-drug use in sex partners.

Service use patterns of youth with, and at high risk for, HIV: a care typology

This paper uses confirmatory structural equation models to develop and test a theoretical model for understanding the service utilization history of 4679 youth who received services from 10 national HIV/AIDS demonstration models of youth-appropriate and youth-attractive services funded by the Special Projects of National Significance (SPNS) Program, HIV/AIDS Bureau, Health Resources and Services Administration. Although the projects differ from one another in the areas of emphasis in their service models, each is targeted to youth at high risk for HIV, or those youth who have already contracted HIV. Collectively, the projects represent a comprehensive adolescent HIV service model. This paper examines the characteristics of the services provided to young people ranging from outreach to intensive participation in medical treatment. Major typologies of service utilization are derived empirically through exploratory factor and cluster analysis methods. Confirmatory structural equation modeling methods are used to refine the exploratory results using a derivation and replication strategy and methods of statistical estimation appropriate for non-normally distributed service utilization indicators. The model hypothesizes that youth enter the service system through a general construct of connectedness to a comprehensive service model and through service-specific methods, primarily of outreach or emergency services. Estimates are made of the degree to which a comprehensive service model drives the services as opposed to specific service entry points.

Human immunodeficiency virus-infected adolescents: a descriptive study of older children in New York City, Los Angeles County, Massachusetts and Washington, DC

BACKGROUND

Children infected with HIV are entering adolescence with challenging and changing medical and social needs. Through chart review we describe certain medical and social characteristics of adolescents who acquired HIV as children.

METHODS

HIV-infected children 12 years of age and older in 1995 were monitored through the Pediatric Spectrum of HIV Disease study from four US sites. In addition to standard 6-month medical chart reviews, a special chart abstraction in 1997 collected available psychosocial and sexual history information.

RESULTS

A total of 131 adolescents HIV-infected as children were studied: 52 infected perinatally; 44 infected through a contaminated blood transfusion; 30 through receipt of contaminated blood products for hemophilia; and 5 with unknown transmission mode. Mean age at last medical contact was 15.5 years, 67% were Hispanic or African-American, 12% were employed, 66% attended regular school, 66% knew their HIV status and 48% (8% for the perinatally infected) lived with their biologic mother. Information on sexual activity showed that 18% had sexual relations, 28% did not and for 53% sexual activity was not recorded in the medical chart. Four percent used illicit drugs, which along with sexual activity showed a positive association with age. Forty-two percent had an AIDS-defining opportunistic infection, and 56% had a recent CD4+ lymphocyte count <200 cells/microl.

CONCLUSIONS

Adolescents in this study represent a heterogeneous group of surviving HIV-infected children some of whom are sexually active and potential sources of HIV transmission. Clinicians who treat HIV-infected and high risk adolescents face the challenges of providing care and prevention services appropriate to adolescent development.

HIV and AIDS in adolescents

HIV infection in adolescents continues to challenge health care providers, policy makers, and advocates for youth. Primary care providers working with parents of adolescents and at-risk youth are in a unique position to identify or help develop HIV prevention and care programs that address many needs. Effective interventions are those that move beyond moralism to realism and a willingness to engage youth and their families. Youth at high risk for HIV should be identified and engaged in primary care as soon as possible. HIV-infected youth need intensive individual and group interventions to keep themselves healthy and reduce transmission to others. Incumbent on all providers is to make adolescents' services visible, flexible, affordable, confidential, culturally appropriate, and available for all youth.

Condom use in young blacks and Hispanics in public STD clinics

BACKGROUND AND OBJECTIVES

Young blacks and Hispanics are an emerging risk group for contracting HIV. The goal of this study was to assess the most salient correlates of condom use for young Hispanics and blacks in Los Angeles county sexually transmitted diseases (STD) clinics as a first step toward designing a short clinic-based intervention.

STUDY DESIGN

Face-to-face interviews were conducted with 376 patients younger than the age of 27 years at six STD clinics operated by the Los Angeles County Department of Health Services. Assessment included several attitudinal variables and AIDS risk behaviors.

RESULTS

Condom use at last intercourse ranged from 40% among Hispanic females to 48% among black males. Among females, condom users were more likely to report high self-efficacy regarding condom use, peer norms supporting condom use, and more sexual communication than respondents who did not use a condom at last intercourse. Among males, no relationship was found between condom use at last intercourse and these attitudinal variables, except for sexual communication. The most important correlate of condom use among males and females was the frequency of carrying condoms.

CONCLUSIONS

Our findings suggest that offering educational group sessions and attractive means for carrying condoms to patients in STD clinics may have the potential to increase condom use. The efficacy of these intervention strategies should be explored in future studies.

Attempting to enhance the enrollment of adolescents into AIDS clinical trials: the design of ACTG Protocol 220

The epidemic of HIV infection continues to grow in adolescents and young adults. Unfortunately, because treatment regimens have been developed based on data derived from clinical trials, little data are available on adolescents because they are infrequently included in these trials. In an effort to facilitate the enrollment of more adolescents into AIDS Clinical Trials Group (ACTG) clinical trials, we designed a nontreatment protocol to familiarize adolescents with clinical trials requirements. Two hundred fifty-six adolescents (150 females, 106 males) between the ages of 13 and 21 years were enrolled at 43 different clinical trials sites throughout the United States. The majority of patients (50%) were enrolled at sites that had specific programs for adolescents. Most of the young women (85%) had acquired their infection via heterosexual transmission, whereas the largest transmission categories in men were blood or factor transfusions (43%) or same-sex contact (34%). Admission CD4 counts were lower in males (mean = 396 cells/mm3) than in females (mean = 513 cells/mm3) (p = 0.01). Psychosocial profiles revealed a variety of ongoing risk behaviors in HIV-infected adolescents. Two years into the study, 223 patients are still being observed. We conclude that adolescents can be enrolled in an observational protocol. The success of this trial will be determined by how many ACTG Protocol 220 participants are ultimately enrolled in therapeutic trials.

Overview of the Special Projects of National Significance Program's 10 models of adolescent HIV care

Ten models of adolescent human immunodeficiency virus (HIV) care were funded in 1993 by the Special Projects of National Significance (SPNS) Program, HIV/Acquired Immunodeficiency Virus (AIDS) Bureau, Health Resources and Services Administration, through the Ryan White CARE Act. These models were supported to advance knowledge about the engagement of HIV-positive and at-risk adolescents and young adults in care. This article provides an overview of the SPNS Program's adolescent initiative, which developed and evaluated innovative models of HIV care, and provides background information on and summarizes the 10 models of care. The models are organized into four groups emphasizing different concepts: (a) youth involvement; (b) outreach to bring youth into services; (c) case management and linkage to services; and (d) a comprehensive continuum of care for youth.

Boston HAPPENS Program: a model of health care for HIV-positive, homeless, and at-risk youth. Human immunodeficiency virus (HIV) Adolescent Provider and Peer Education Network for Services

The Boston HAPPENS [Human immunodeficiency virus (HIV) Adolescent Provider and Peer Education Network for Services] Program is a project supported by Special Projects of National Significance (SPNS) Program, HIV/AIDS Bureau, Health Resources and Services Administration, which provides a network of care for homeless, at-risk, and HIV-positive youth (ages 12-24 years), involving eight agencies. The program has provided services to 1301 youth, including 46 who are HIV-positive. Boston HAPPENS provides a citywide network of culturally and developmentally appropriate adolescent-specific care, including: (a) outreach and risk-reduction counseling through professional and adult-supervised peer staff, (b) access to appropriate HIV counseling and testing support services, (c) life management counseling (mental health intake and visits as part of health care and at times of crisis), (d) health status screening and services needs assessment, (e) client-focused, comprehensive, multidisciplinary care and support, (f) follow-up and outreach to ensure continuing care, and (g) integrated care and communication among providers in the metropolitan Boston area. This innovative network of youth-specific care offers a continuum from street outreach to referral and HIV specialty care that crosses institutional barriers.

Managing sexually transmitted diseases in adolescents

Control of sexually transmitted diseases (STDs) in adolescents is a primary responsibility of health care providers. Using the tools of history and physical examination, and drawing on the awareness of different stages of adolescent development, health care providers can define at-risk for STDs. This article discusses screening practices, disease control through reporting and preventive counseling, and treatment guidelines for common STD syndromes.

The pediatrician and the sexually active adolescent. A primer for sexually transmitted diseases

Sexual activity is a common practice among young adolescents, placing them at high risk for STDs, many of which have long-term consequences. Early diagnosis and treatment are essential to limit both the consequences and the spread of these infections. The clinician has a responsibility to the adolescent patient to recognize and treat these diseases. Using history and physical examination, the clinician should be able to determine an adolescent's risk for an STD, and, based on this risk, undertake the appropriate evaluations. Patient treatment, follow-up, and management of sex partners are then guided by the results of either presumptive or definitive diagnostic tests.
