Adolescent and Young Adult Health and Behaviors Working Group
Chair: Barbara Moscicki, MD, Professor of Pediatrics, University of California Los Angeles
Chair: Katherine Tassiopoulos, DSc, Senior Research Scientist, Harvard T. H. Chan School of Public Health
The primary aims of the Adolescent and Young Adult Health and Behaviors Working Group are to: define the impact of perinatal HIV infection and ARV exposure on behavioral health outcomes including sexual behaviors, substance use, mental health, independent living skills, vocational/educational achievement, and social relationships, as PHIV and PHEU youth transition through adolescence and young adulthood; determine the prevalence and incidence of reproductive health outcomes including pregnancies, sexually transmitted infections, menstrual irregularity and precancerous HSIL; and, among PHIV adolescents and young adults, to describe the individual, social, and health care system barriers and facilitators of (a) transitioning from pediatric to adult health care, (b) adherence to medications and retention in health care, and (c) physical and mental health. Examples of analyses the working group has undertaken include examining the co-occurrence of sexual, substance use, and mental health behavior risks in PHIV and PHEU youth; understanding the association between exposure to violence and virologic and immunological outcomes in PHIV youth; identifying factors associated with initiation of sexual activity and unprotected sex among PHIV youth; estimating the agreement between self-reported measures of antiretroviral treatment adherence and HIV RNA viral load; examining the prevalence of and risk factors for substance use among PHIV and PHEU youth; and a comparison of HPV antibodies and effectiveness between HPV-vaccinated PHIV and PHEU youth.

Cardiopulmonary Working Group
Chair: Engi Attia, MD, PhD, Acting Assistant Professor, Division of Pulmonary, Critical Care, and Sleep Medicine, University of Washington
Chair: Steven Lipshultz, MD, A. Conger Goodyear Professor and Chair, Department of Pediatrics, University at Buffalo
Chair: Paige Williams, PhD, Senior Lecturer on Biostatistics, Harvard T. H. Chan School of Public Health
The primary aims of the Cardiopulmonary Working Group (CPWG) are to (1) evaluate the effects of HIV and antiretroviral (ARV) treatment on cardiac and pulmonary function in children and adolescents with perinatally-acquired HIV infection (PHIV) or perinatally-exposed to HIV but uninfected (PHEU), (2) evaluate the safety of ARV treatment given to HIV-infected pregnant women on cardiac and pulmonary health of their children, and (3) explore the pathophysiologic mechanisms of cardiopulmonary abnormalities in PHIV and PHEU children and adolescents. The CPWG is comprised of 10-20 experts in cardiology, pulmonology, immunology, pediatrics, biostatistics, and epidemiology.
Some of the past projects include evaluation of serum biomarkers of cardiac function in both PHEU and PHIV children, echocardiographic measures of cardiovascular function and structure, and pulmonary function tests of PHIV and PHEU children. In terms of cardiovascular objectives, we have evaluated predictors of elevated cardiac and inflammatory biomarkers (such as C-reactive protein), and demonstrated associations of these biomarkers with echocardiographic measures among PHEU and PHIV children in both the PHACS SMARTT and AMP studies. We have also shown that PHIV children in the contemporary ARV era have marked improvement in cardiac function based on echocardiographic measures as compared to cohorts with perinatal HIV infection studied earlier in the HIV epidemic, but still show some differences from PHEU children of similar ages in the PHACS AMP study. In terms of pulmonary function, we demonstrated an increased risk of asthma and pulmonary complications in the PHIV children in AMP as compared to the PHEU controls, with some findings based on a PHACS substudy, the Ancillary Pulmonary Complications of HIV Infection study, in which pulmonary function tests were conducted in order to better understand the role of HIV in asthma and other pulmonary diseases.
Some of the current projects of the CPWG group include an R01-funded grant to conduct repeat echocardiograms on PHIV and PHEU young adults who previously had these performed in the AMP study about 10 years ago. This NHLBI-funded project will also include pulse wave velocity testing and collection of blood samples for evaluation of a comprehensive suite of cardiac and inflammatory biomarkers and markers of mitochondrial dysfunction. Another current project involves cardiac and pulmonary imaging studies of a small subset of PHIV young adults. Last of all, additional pulmonary studies are ongoing including an analysis to compare pulmonary function between PHIV and PHEU children and adolescents in the US to those in Kenya, and to better understand the mechanisms underlying obstructive lung disease.
The CPWG has also coordinated with other working groups to participate in research with overlapping interests. For example, the CPWG collaborated with the Metabolic, Nutrition, and Growth Working Group on an analysis of cardiac risk factors in adolescents aged 15 or older, based on risk prediction models, and completed two projects related to vitamin D deficiency and its relation to HIV infection status and echocardiographic outcomes. The creation of a DNA library on PHACS subjects also was strongly endorsed by the CPWG.
New directions of future research include proposals to use the extensive genotyping information obtained from the PHACS AMP study to better understand whether certain mutations may predispose patients to cardiovascular or pulmonary complications. These proposed genetic studies will take the PHACS program well into the next era of HIV medicine, namely the role of genetics in diagnosis and management of HIV infection in children, adolescents, and young adults.

Complications Working Group
Chair: Kunjal Patel, DSc, MPH, Senior Research Scientist, Harvard T. H. Chan School of Public Health
Chair: Russell Van Dyke, MD,Principal Investigator, PHACS Coordinating Center, Tulane University
The primary aim of the Complications working group is to identify infectious and non-infectious complications of HIV disease and evaluate their associations with antiretroviral therapy. Our working group therefore focuses on the AMP and AMP Up protocols of PHACS which include youth and young adults with perinatal HIV-infection and a comparison group of perinatally HIV-exposed but uninfected participants. Examples of our working group activities include examining trends in antiretroviral drug use, CD4 counts, HIV viral loads, and diagnoses; evaluating long-term treatment management strategies in the context of antiretroviral treatment failure, drug resistance and HIV tropism; comparing the effectiveness of vaccines for measles, mumps, rubella, varicella, and human papillomavirus among infected and uninfected youth and identifying correlates of effective immune responses; examining the relationship between tenofovir use and renal disease; estimating the prevalence of liver disease; examining oral health including the prevalence of dental caries and periodontal disease; identifying biomarkers of low proviral load to inform future cure and therapeutic vaccine strategies; and establishing a DNA repository for genomic studies. Our working group has also collaborated with international pediatric cohorts to answer research questions relevant to the global perinatal HIV epidemic.

COVID-19 Task Force
Chair: Denise Jacobson, PhD, MPH, Harvard T.H. Chan School of Public Health
Chair: Sue Siminski, MS, MBA, Principal Investigator, Frontier Science
Genomics Task Force
Chair: Sean Brummel, PhD, Senior Research Scientist, Harvard T.H. Chan School of Public Health
Chair: Stephen Spector, MD, Distinguished Professor of Pediatrics, University of California San Diego
The PHACS Genomics Task Force aims to promote and support genomic, epigenetic, and other “Omics” PHACS study proposals and analyses among HIV affected populations. Genomic studies in PHACS have focused on Single Nucleotide Polymorphisms (SNPs) and their associations with neurocognitive outcomes and bone mineral density. Genomic studies have also investigated the relationship between self-reported race and ancestry markers. While self-reported race is a critical measure for understanding the health impact of individuals' lived experiences of racism, some studies have incorrectly attributed differences by self-reported race to differences in genetics. Our findings showed great diversity in ancestry markers within self-reported racial groups, illustrating that self-reported race is not a proxy for genetic background. Additional genetic studies identified 3 SNPs within CCRL2, RETREG1, and YWHAH that are associated with neurocognitive impairment of children perinatally infected with HIV. Whereas a variant of CCRL2 is associated with a decreased risk of cognitive impairment and decreased inflammation, variants of RETREG1 and YWHAH are associated with an increased risk of cognitive impairment and increased inflammation. These findings suggest that therapeutic approaches that decrease inflammation may be of benefit to HIV-infected children with impaired cognitive function. Epigenetic analyses have focused on the effect of ART during pregnancy on global methylation in neonates and on the effect of living with HIV on epigenetic aging.

Hearing and Language Task Force
Chair: Peter Torre, PhD, Associate Professor, School of Speech, Language, and Hearing Science, San Diego State University
Chair: Tzy-Jyun Yao, PhD, Senior Statistician, Harvard T. H. Chan School of Public Health
The Hearing/Language Working Group is a team of hearing scientists, speech/language pathologists, pediatricians, psychologists, epidemiologists and statisticians whose main goal is to examine the effects of HIV and/or antiretroviral therapy (ART) exposures on hearing and/or language acquisition in youth who were exposed to HIV or infected perinatally. Examples of our working group activities include investigations of hearing mechanisms, language acquisition in infants and toddlers, risk for and consistency of language impairments in school-aged children, and the persistence of language impairments into adulthood. We are also interested in the safety of ART treatment and in the effects of congenital infections and other comorbid maternal conditions on language development and hearing outcomes in HIV-exposed uninfected children.

Maternal Exposures Working Group
Chair: Ellen Chadwick, MD, PHACS Principal Investigator, Ann & Robert H. Lurie Children's Hospital of Chicago
Chair: Deborah Kacanek, ScD, Social Epidemiologist, Harvard T. H. Chan School of Public Health
The Maternal Exposures Working Group examines the relationship of individual, clinical, and social factors during pregnancy and motherhood among women living with HIV to birth outcomes and health of their children. Our studies focus on evaluating associations of maternal HIV disease severity, use of specific antiretroviral drugs, maternal mental health and substance use with pregnancy outcomes (e.g., gestational age at birth, the size of the newborn, mode of delivery, subtle or major birth defects), as well as child health and development through young adulthood. As newer antiretroviral drugs are used more widely, we conduct studies to evaluate the safety of their use during pregnancy. We apply novel strategies to measure the amount of antiretroviral drugs that cross the placenta and into the fetus by examining presence in meconium (the first stools produced by the newborn) and maternal and infant hair. Our studies also seek to determine whether events that happen in pregnancy affect the genetics of the body (epigenetic studies) and the energy system of the cells (mitochondrial function).

Chair: Lei Wang, PhD, Professor, Department of Psychiatry and Behavioral Health, Ohio State University College of Medicine
The Mental Health, Neurodevelopment and Neurologic Conditions Working Group is a team of psychologists, psychiatrists, neurologists, pediatricians, epidemiologists and statisticians whose main goal is to examine the neurodevelopmental and neurological effects of HIV and/or antiretroviral medications (ARTs) on youth who were exposed or infected perinatally. We examine the potential short- and long-term consequences of exposure to or infection with HIV and its treatment on cognition, academic achievement, and on the neurological, emotional, and behavioral development of youth over time. We also examine how the environment and other possible stressors and/or protectors contribute to all of these developmental outcomes.

Nutrition-Growth-Metabolism Working Group
Chair: Denise Jacobson, PhD, Senior Research Scientist, Harvard T. H. Chan School of Public Health
Chair: Jennifer Jao, MD, MPH, Associate Professor of Pediatrics, Northwestern Feinberg School of Medicine, Ann & Robert H. Lurie Children's Hospital of Chicago
The primary aims of Nutrition-Growth-Metabolic Working Group are to investigate the effects of HIV and antiretroviral medications on aspects of nutrition, growth, and metabolism in children, youth and young adults living with perinatally acquired HIV infection (PHIV) and those who are perinatally HIV-exposed but uninfected (PHEU). We are also investigating nutrition and metabolic issues in pregnant women living with HIV and their effects on birth and child outcomes. In particular, we have published studies on distribution of fat mass, the prevalence and incidence of insulin resistance, pubertal onset, vascular markers of endothelial dysfunction, cardiovascular disease risk, bone mineral density, vitamin D and parathyroid levels and associations with bone density in PHIV compared to PHEU and mitochondrial abnormalities and insulin resistance, and changes in lipids after switching to newer protease inhibitor agents. In PHEU children we have published many studies evaluating growth and metabolic abnormalities associated with in utero antiretroviral medication exposure . Currently we are investigating fracture rates since birth, blood pressure and cardiac health, physical activity, lipid abnormalities, longitudinal assessments of bone growth, and mitochondrial abnormalities among individuals with PHIV, and among those with PHEU, growth patterns by preterm birth, small-for-gestational age, and maternal PHIV status.

Oral Health Task Force
Chair: Barbara Moscicki, MD, Professor of Pediatrics, University of California Los Angeles Chair: Mark Ryder, DMD, Professor of Orofacial Sciences, University of California San Francisco
Chair: Caroline Shiboski, DDS, PhD, Professor of Orofacial Sciences, University of California San Francisco
Chair: Tzy-Jyun Yao, PhD, Harvard T.H. Chan School of Public Health
The primary aims of the Oral Health Task Force are to identify factors associated with poor oral health among persons living with perinatal HIV and among those HIV-exposed but uninfected. More specifically, mucosal oral health, periodontal health and enamel (caries) health are targeted. Factors affecting oral health that we examine include behavioral (oral hygiene, tobacco, alcohol and other substance use), as well as adverse effects of ARV and inflammation. Biomarkers of inflammation are examined by assaying crevicular fluid and saliva samples for cytokines, chemokines, and bone turnover markers. In addition, the task force examines social determinants of access to dental care. Examples of our findings include the observation that gingivitis or periodontitis was quite common (around 80%) among those living with PHIV and caries (cavities) were higher in those living with PHIV compared to those with PHEU. Among those living with PHIV, integrase strand inhibitors appeared to be associated with caries. We also found that inflammation using biomarkers was associated with periodontal inflammation among those living with PHIV but not among those PHEU suggesting youth living with PHIV may be at higher risk for developing significant periodontal diseases which are associated with tooth loss and HIV progression. In another study examining metabolites, we showed that individuals with periodontitis had high levels of cadaverine, suggesting that HIV infection, or its treatment, may influence the metabolism of oral bacteria.
The task force completed a follow-up study. The future goal is to study the change of oral health over time and the factors to predict incidence or progression with the collected information.

The impact of sleep on health among people affected by HIV, as well as the impact of HIV treatments and overall health on their sleep, are of great concern to PHACS participants affected by HIV and the PHACS scientific community. The overall aim of the Sleep Task Force is to use the wide-ranging resources of the PHACS network to respond to research interest and community concerns about sleep and advance our knowledge of sleep health and difficulties among groups affected by HIV; the multifactorial influences affecting sleep over time, particularly those specific to the community of people affected by HIV (for example, environmental factors, stress, mental health, HIV treatment); the impact of sleep on health, cognition, mental health, quality of life, and aging; and ways to intervene to improve sleep among the PHACS community.
With this aim in mind, the short and long-term goals of the PHACS Sleep Task Force are to identify gaps in our knowledge about sleep and HIV; to serve as a resource for PHACS or PHACS-affiliated studies regarding measures of sleep; to develop stand-along surveys on sleep issues that can be conducted remotely or within PHACS studies and HOPE; and to propose and develop sleep-focused studies supported by new grant funding.
Women's Health Working Group

The mission of the Women’s Health Working Group (WHWG) is to address the health and well-being of reproductive aged women living with or affected by HIV through impactful research driven by PHACS community members, including CAB members, study staff and investigators, and to support new investigators to conduct women’s health research. Working with women participating in SMARTT, AMP, AMP UP and AMP UP Lite protocols of PHACS, we foster collaborative research efforts to expand our understanding of health issues which have an impact on women living with HIV. Examples of research in progress include studies examining trends in ART prescribing patterns for pregnant women, determinants of viral suppression and CD4 in repeat pregnancies, substance use in pregnancy and in the postpartum period, associations of ART with hypertensive disorders of pregnancy, and relationship of antiretroviral treatment (ART) to weight gain during pregnancy and postpartum. The WHWG is committed to investigating biomedical, as well as social determinants of women’s physical health, mental health, and health-related behaviors to inform guidelines and policies to optimize the health of women living with or affected by HIV.
