Country of Birth of Children With Diagnosed HIV Infection in the United States, 2008-2014

Prevented perinatal HIV infections in the era of antiretroviral prophylaxis and treatment, United States, 1994-2020

OBJECTIVE

The primary aim of this serial cross-sectional analysis is to estimate the total number of prevented perinatal HIV transmissions from the time of the initial recommendation for perinatal zidovudine (ZDV) prophylaxis in 1994 through 2020 in the US.

METHODS

The estimated number of prevented transmissions was calculated as annual differences between expected and observed numbers of perinatal HIV transmissions. Annual expected number of transmissions was estimated by multiplying the annual number of births to women with HIV by 0.2255 (22.55%), i.e., the transmission rate of the control group in the ACTG Protocol 076 trial. We used published point estimates or, if only ranges were given, the midpoints of those ranges as the best estimates of the annual numbers of births to women with HIV and infants with perinatal HIV. When data were not available, we linearly interpolated or extrapolated the available data to obtain estimated numbers for each year.

RESULTS

Between 1978 and 2020, the approximate number of live births to women with HIV was 191 267 (95% confidence interval [CI] 190 392-192 110) and for infants with diagnosed perinatal HIV, it was 21 379 (95% CI 21 088-21 695). Since 1994, the annual number of infants born with HIV decreased from 1263 (95% CI 1194-1333) to 33 in 2019 (95% CI 22-45) and 36 in 2020 (95% CI 25-48), corresponding to a 97% reduction. Cumulatively, an estimated total of 22 732 (95% CI 21 340-24 462) perinatal HIV infections were prevented from 1994 through to 2020.

CONCLUSION

The elimination of perinatal HIV transmission-accompanied by the cumulative number of prevented cases exceeding that of perinatal HIV infections-is a major public health achievement in the US.

Adoption is not associated with immunological and virological outcomes in children with perinatally acquired HIV infection in the Netherlands

OBJECTIVES

To provide an overview of the demographics, treatment characteristics and long-term outcomes of children with perinatal HIV-1 infection (PHIV) living in the Netherlands (NL) and to specifically investigate whether outcomes differ by children's adoption status.

DESIGN

A prospective population-based open cohort including children with PHIV in NL.

METHODS

We included children with PHIV who had entered HIV care in NL since 2007, in view of a sharp increase in the number of adopted children with PHIV since that year. We compared the proportion with virologic suppression and CD4+T-cell count over time between the following groups of children with PHIV: adopted and born outside NL, non-adopted born in NL, and non-adopted born outside NL, using generalized estimating equations and linear mixed effects models, respectively. To account for the variation in cohort inclusion, we analyzed data of children exposed to at least one year of antiretroviral therapy (ART).

RESULTS

We included 148 children (827.5 person-years of follow-up, 72% adopted, age at start care in NL 2.4 (0.5-5.3)). Under-18 mortality was zero. Over the years, a boosted PI-based regimen was most often prescribed. The use of integrase inhibitors increased since 2015. Non-adopted children born in NL were less likely to achieve virological suppression compared to adopted children (OR 0.66, 95%CI 0.51-0.86, p = 0.001), which disappeared after excluding one child with suspected treatment nonadherence (OR 0.85, 95%CI 0.57-1.25, p = 0.400). CD4+T-cell Z-score trajectories were not significantly different between groups.

CONCLUSIONS

Despite considerable and increasing diversity of the population of children with PHIV in NL, geographical origin and adoption status do not seem to pose important challenges in achieving good immunological and virological outcomes.

High Rates of Viral Suppression and Care Retention Among Youth Born Outside of the United States with Perinatally Acquired HIV

BACKGROUND

Youth born outside of the US with perinatally acquired HIV infection (YBoUS-PHIV) account for most children living with HIV in the US, but there are few data characterizing their care outcomes.

METHODS

We conducted a retrospective study of YBoUS-PHIV receiving care across 3 HIV clinics in the Southeastern US between October 2018 and 2019. Primary outcomes were retention in care and viral suppression defined as (1) proportion of suppressed viral loads (VLs) and (2) having all VLs suppressed (definition 1 presented in the abstract). Primary predictors were age, adoption and disclosure status (full, partial and none/unknown). Multivariable logistic regression and χ 2 tests were used to test for associations with care outcomes. Analysis of disclosure status was restricted to youth greater than or equal to 12 years.

RESULTS

The cohort included 111 YBoUS-PHIV. Median age was 14 years (interquartile range, 12-18), 59% were female, and 79% were international adoptees. Overall, 84% of patients were retained in care, and 88% were virally suppressed at each VL measurement. Adopted youth were more likely to be virally suppressed than nonadopted youth [odds ratio (OR), 7.08; P < 0.01] although the association was not statistically significant in adjusted analysis (adjusted OR, 4.26; P = 0.07). Neither age nor adoption status was significantly associated with retention. Among 89 patients greater than or equal to 12 years, 74% were fully disclosed of their HIV status, 12% were partially disclosed, and 13% had not started the disclosure process. There was no significant difference in retention or viral suppression by disclosure status.

CONCLUSIONS

YBoUS-PHIV achieved high rates of retention and viral suppression. Adopted youth may be more likely to achieve viral suppression which may reflect the need for tailored interventions for nonadopted youth.

Optimizing Disclosure of HIV Status to a Diverse Population of HIV-Positive Youth at an Urban Pediatric HIV Clinic

PURPOSE

The purpose of the study was to increase the proportion of youth living with HIV (YLWH) aged ≥11 years who undergo developmentally appropriate disclosure about their HIV status.

METHODS

A quality improvement project was initiated at an urban pediatric HIV clinic between July 2018 and March 2020. The primary outcome measure was the proportion of YLWH aged ≥11 years who were disclosed to about their HIV status. The proportion of undisclosed YLWH who had documented nondisclosure status was also assessed as a process measure. Plan-Do-Study-Act (PDSA) cycles for change included monthly clinic staff check-ins to discuss new disclosures, quarterly team meetings to discuss strategies to improve disclosure, and modifying a clinic note template to prompt providers to document disclosure status. Annotated run charts were used to analyze the data.

RESULTS

Before the first PDSA cycle, 26/46 (57%) of the target population of YLWH aged ≥11 years had their HIV status disclosed to them, and none of the undisclosed youth had disclosure status documented in their medical record. After 20 months and six PDSA cycles, the proportion of YLWH aged ≥11 years disclosed to about their HIV status increased to 80% and the proportion of undisclosed YLWH with documentation of their disclosure status increased to 100%.

CONCLUSIONS

Several interventions integrated throughout the pediatric HIV care process were associated with an increase in the proportion of YLWH with developmentally appropriate HIV disclosure and documentation of disclosure status, an important psychosocial aspect of care in these individuals.

A Scoping Review of the Health of African Immigrant and Refugee Children

Migration is a growing phenomenon around the world, including within the African continent. Many migrants, especially African children, face challenges related to health and social inclusion and can face increased health risks. A systematic scoping review of available literature on the health of African migrant children across the globe was conducted to offer insight into these health risks. The review was conducted over a 15-month period from January 2019 to April 2020, yielding 6602 articles once duplicates were removed. This search included electronic databases, reference lists of articles reviewed, and searches of libraries of relevant organisations. A total of 187 studies met the inclusion criteria, of which 159 were quantitative, 22 were qualitative, and 6 used mixed methods. The findings reveal decreased health in this population in areas of nutrition, infectious diseases, mental health, birth outcomes, sexual and reproductive health, physical and developmental health, parasitic infections, oral health, respiratory health, preventative health, endocrine disorders, health care services, and haematological conditions. The findings offer insights into factors influencing the health of African immigrant and refugee children. Further studies, especially qualitative studies, are needed to determine barriers to service access after migration and to investigate other underexplored and overlooked health concerns of African migrant children, including pneumonia and child maltreatment.

Eliminating perinatal HIV in the United States: mission possible?

: In 2015, only 53 infants born in the United States acquired HIV - the lowest recorded number of perinatal HIV infections. Recognizing this significant achievement, we must acknowledge that the United States has not yet reached the goal of eliminating perinatal HIV transmission. This analysis describes different approaches to perinatal HIV preventive services among five states and the District of Columbia as case studies. Continuous focus on improving identification, surveillance and prevention of HIV infection in pregnant women and their infants is necessary to reach the goal of eliminating perinatal HIV transmission in the United States.
