(Last updated: March 5, 2015; last reviewed: March 5, 2015)
These updated guidelines address the use of combination antiretroviral therapy (cART) for HIV-infected infants, children, and adolescents (through puberty). Guidance on management of adverse events associated with use of antiretroviral (ARV) drugs in children and a detailed review of information about safety, efficacy, and pharmacokinetics (PK) of ARV agents in children is also included. The Department of Health and Human Services (HHS) Panel on Antiretroviral Therapy and Medical Management of HIV-Infected Children (the Panel), a working group of the Office of AIDS Research Advisory Council (OARAC), reviews new data on an ongoing basis and provides regular updates to the guidelines. The guidelines are available on the AIDSinfo website at http://aidsinfo.nih.gov.
The AIDSinfo website also includes separate guidelines for the prevention and treatment of opportunistic infections in HIV-exposed and -infected children,1 for the use of ARV agents in HIV-infected (post–pubertal) adolescents and adults,2 for the use of ARV drugs in pregnant HIV-infected women,3 and for the prevention and treatment of opportunistic infections in HIV-infected adults.4 These guidelines are developed for the United States and may not be applicable in other countries. The World Health Organization (WHO) provides guidelines for resource-limited settings at http://www.who.int/hiv/pub/arv/en.
Since the guidelines were first developed in 1993 (with the support of the François-Xavier Bagnoud Center, Rutgers, The State University of New Jersey), advances in medical management have dramatically reduced morbidity and mortality in HIV-infected children in the United States. Mortality in children with perinatal HIV infection has decreased by more than 80% to 90% since the introduction of protease inhibitor-containing combinations and opportunistic and other related infections in children have significantly declined in the era of cART.5,6 ARV drug resistance testing has enhanced the ability to choose effective initial and subsequent regimens. Treatment strategies continue to focus on timely initiation of cART regimens capable of maximally suppressing viral replication in order to prevent disease progression, preserve or restore immunologic function, and reduce the development of drug resistance. At the same time, availability of new drugs and drug formulations has led to more potent regimens with lower toxicity, lower pill burdens, and less frequent medication administration, all factors that can improve adherence and outcomes. The use of ARV drugs in HIV-infected pregnant women has resulted in a dramatic decrease (to less than 2%) in the rate of HIV transmission to infants in the United States. In addition to decreasing numbers of infants with HIV infection, children in the United States who are HIV-infected are less likely to develop AIDS because of routine and early institution of effective cART.7,8 Finally, as a group, children living with HIV infection are growing older, bringing new challenges related to adherence, drug resistance, reproductive health planning, transition to adult medical care, and the potential for long-term complications from HIV and its treatments.9,10
The pathogenesis of HIV infection and the virologic and immunologic principles underlying the use of cART are generally similar for all HIV-infected individuals, but unique considerations exist for HIV-infected infants, children, and adolescents, including:
The recommendations in these guidelines are based on the current state of knowledge regarding the use of ARV drugs in children. Evidence is drawn primarily from published data regarding the treatment of HIV infection in infants, children, adolescents, and adults; however, when no such data were available, unpublished data and the clinical expertise of the Panel members were also considered. The Panel intends for these guidelines to be flexible and not to replace the clinical judgment of experienced health care providers.
Guidelines Development Process
An outline of the composition of the Panel and the guidelines process can be found in Table 1.
|Goal of the Guidelines||Provide guidance to HIV care practitioners on the optimal use of ARV agents in HIV-1-infected infants, children, and adolescents (through puberty) in the United States.|
|Panel Members||The Panel is composed of approximately 32 voting members who have expertise in management of HIV infection in infants, children, and adolescents. Members include representatives from the Committee on Pediatric AIDS of the American Academy of Pediatrics and community representatives with knowledge of pediatric HIV infection. The Panel also includes at least one representative from each of the following HHS agencies: Centers for Disease Control and Prevention (CDC), Food and Drug Administration (FDA), Health Resources and Services Administration (HRSA), and the National Institutes of Health (NIH). A representative from the Canadian Pediatric AIDS Research Group participates as a nonvoting, ex officio member of the Panel. The U.S. government representatives are appointed by their respective agencies; nongovernmental members are selected after an open announcement to call for nominations. Each member serves on the Panel for a 3-year term with an option for reappointment. A list of current members can be found in the Panel Roster.|
|Financial Disclosure||All members of the Panel submit a financial disclosure statement in writing annually, reporting any association with manufacturers of ARV drugs or diagnostics used for management of HIV infections. A list of the latest disclosures is available on the AIDSinfo website (http://aidsinfo.nih.gov).|
|Users of the Guidelines||Providers of care to HIV-infected infants, children, and adolescents|
|Developer||Panel on Antiretroviral Therapy and Medical Management of HIV-Infected Children-a working group of OARAC|
|Funding Source||Office of AIDS Research, NIH and Health Resources and Services Administration|
|Evidence Collection||A standardized review of recent relevant literature related to each section of the guidelines is performed by a representative of the François-Xavier Bagnoud Center and provided to individual Panel section working groups. The recommendations are generally based on studies published in peer-reviewed journals. On some occasions, particularly when new information may affect patient safety, unpublished data presented at major conferences or prepared by the FDA and/or manufacturers as warnings to the public may be used as evidence to revise the guidelines.|
|Recommendation Grading||Described in Table 2.|
|Method of Synthesizing Data||Each section of the guidelines is assigned to a small group of Panel members with expertise in the area of interest. The members synthesize the available data and propose recommendations to the Panel. The Panel discusses and votes on all proposals during monthly teleconferences. Proposals endorsed by a consensus of members are included in the guidelines as official Panel recommendations.|
These guidelines focus on HIV-infected infants, children, and adolescents through puberty. For more detailed discussion of issues of treatment of postpubertal adolescents, the Panel defers to the designated expertise offered by the Panel on Antiretroviral Guidelines for Adults and Adolescents.
Separate guidelines outline the use of cART in HIV-infected pregnant women and interventions for prevention of perinatal transmission, cART for nonpregnant HIV-infected adults and postpubertal adolescents, and ARV prophylaxis for those who experience occupational or nonoccupational exposure to HIV. These guidelines are also available on the AIDSinfo website (http://www.aidsinfo.nih.gov).
|Update Plan||The full Panel meets monthly by teleconference to review data that may warrant modification of the guidelines. Smaller working groups of Panel members hold additional teleconferences to review individual drug sections or other specific topics (e.g., What to Start). Updates may be prompted by new drug approvals (or new indications, formulations, or frequency of dosing), new significant safety or efficacy data, or other information that may have a significant impact on the clinical care of patients. In the event of significant new data that may affect patient safety, the Panel may issue a warning announcement and post accompanying recommendations on the AIDSinfo website until the guidelines can be updated with appropriate changes. All sections of the guidelines will be reviewed, with updates as appropriate, at least once yearly.|
|Public Comments||A 2-week public comment period follows release of the updated guidelines on the AIDSinfo website. The Panel reviews comments received to determine whether additional revisions to the guidelines are indicated. The public may also submit comments to the Panel at any time at firstname.lastname@example.org.|
Recommendations in these guidelines are based upon scientific evidence and expert opinion. Each recommendation includes a letter (A, B, or C) that represents the strength of the recommendation and a Roman numeral (I, II, or III) that represents the quality of the evidence that supports the recommendation.
Because licensure of drugs in children often is based on efficacy data from adult trials in addition to safety and PK data from studies in children, recommendations for ARV drugs may need to rely, in part, on data from clinical trials or studies in adults. Pediatric drug approval may be based on evidence from adequate and well-controlled investigations in adults if:
Studies relating activity of the drug-to-drug levels (pharmacodynamic data) in children also should be available if there is a concern that concentration-response relationships might be different in children. In many cases, evidence related to use of ARV drugs is substantially greater from adult studies (especially randomized clinical trials) than from pediatric studies. Therefore, for pediatric recommendations, the following rationale has been used when the quality of evidence from pediatric studies is limited:
Quality of Evidence Rating I–Randomized Clinical Trial Data
Quality of Evidence Rating II–Nonrandomized Clinical Trials or Observational Cohort Data
Quality of Evidence Rating III–Expert opinion
In an effort to increase the amount and improve the quality of evidence available for guiding management of HIV infection in children, the discussion of available trials with children and their caregivers is encouraged. Information about clinical trials for HIV-infected adults and children can be obtained from the AIDSinfo website (http://aidsinfo.nih.gov/ClinicalTrials/) or by telephone at 1-800-448-0440.
