Young adults with perinatally acquired HIV (PAH) face numerous challenges, including antiretroviral therapy (ART) adherence, managing onward HIV transmission risks and maintaining wellbeing. Sharing one's HIV status with others (onward HIV disclosure) may assist with these challenges but this is difficult. We developed and tested the feasibility of an intervention to help HIV status sharing decision-making for young adults with PAH.

HIV remains a significant public health issue among young adults living in Uganda. There is a need for reliable and valid measures of key psychological and behavioural constructs that are related to important outcomes for this population. We translated, adapted and tested the psychometric properties of questionnaires measuring HIV stigma, HIV disclosure cognitions and affect, antiretroviral therapy (ART) adherence, social support, personal values, and hope, using a multi-step process.

We compared virological and immunological outcomes for young adults with perinatally-acquired HIV infection (YAPaHIV) in the year preceding, and year of, UK SARS-CoV-2 lockdown restrictions, in a service that maintained face-to-face appointments. Retrospective single-centre cohort analysis from; Period 1(P1) twelve months before the first national lockdown - 23rd March 2019-23rd March 2020, period 2(P2) twelve months of varied restrictions - 24th March 2020-24th March 2021. Data collected from electronic records included age, ethnicity, sex, HIV viral load (VL) (suppression ≤ 200 copies/ml), CD4 count (cells/μL), clinical events, and appointment frequency/modality.

Background: Increasing numbers of children with perinatally acquired HIV (PaHIV) are transitioning into adult care. People living with behaviourally acquired HIV are known to be at more risk of psychosis than uninfected peers. Young adults living with PaHIV face numerous risk factors; biological: lifelong exposure to a neurotrophic virus, antiretroviral medication and immune dysfunction during brain development, and environmental; social deprivation, ethnicity-related discrimination, and migration-related issues.

HIV-related stressors affecting young adults with perinatally acquired HIV (PHIV+) and their siblings include parental and sibling ill-health and death, own ill-health, HIV disclosure, and stigma. Young people with PHIV+ typically share their HIV status with family members. We explored sibling relationships in young people with PHIV+.

Objective: Adolescence is the only age group globally where HIV-associated mortality is rising, with poorer outcomes at all stages of the care cascade compared with adults. We examined post transition outcomes for young adults living with perinatal HIV.

Design: Retrospective cohort analysis.

Article Synopsis
  • A growing number of young adults with perinatally acquired HIV (PAH) are navigating the challenges of intimate relationships while facing additional stressors related to their condition.
  • The study explored how these individuals manage the complexities of disclosing their HIV status to partners, revealing common themes such as the timing of disclosure and the use of protective measures to avoid revealing their status.
  • Findings indicate a strong impact of HIV disclosure on relationship experiences, highlighting the need for interventions to support young adults with PAH and more research that includes diverse populations and settings.

Emerging evidence suggests financial incentives (FIs) improve medication adherence in select populations. A small proportion of adolescents with perinatal HIV (PaHIV) transfer to adult services with established poor adherence and advanced disease. We describe a single center adherence intervention combining FIs with motivational interviewing (MI).

An increasing number of children born with perinatally acquired HIV (PAH) are surviving into late adolescence and early adulthood. At this developmental stage, developing intimate relationships and having children are potentially important goals with associated normative challenges. Young people with PAH face a variety of additional HIV-related stressors that may be associated with relationships and parenting.

Article Synopsis
  • An increase in children with perinatally acquired HIV are surviving into young adulthood, facing unique challenges in their intimate relationships, including issues of disclosure and stigma.
  • Limited research exists on the experiences of these individuals, specifically focusing on young adults who grew up with HIV.
  • An exploratory study of seven participants revealed themes related to partner perceptions of HIV, such as misconceptions linking it to AIDS, differences in understanding between partners, and concerns about transmission risk, highlighting the need for better support in disclosing HIV status.

Article Synopsis
  • HAART has improved the quality of life for HIV-infected men, but many still report low sexual desire, possibly due to raised estradiol levels from testosterone aromatization.
  • Researchers hypothesized that letrozole, an aromatase inhibitor, could help men with HIV by lowering estradiol levels.
  • A study comparing testosterone injections and letrozole showed that both treatments increased sexual desire and the number of sexual acts without any adverse effects.

There is evidence from our own unit and other workers that many patients who have lipodystrophy on HAART given for HIV disease also have raised oestrogen levels and complain of low sexual desire. This hypothesis paper discusses a possible pathological mechanism for these changes--an increase in the number of fibroblasts and macrophages present in lipoatrophic areas that could convert testosterone to oestrogen by intracellular aromatisation. This process is known to be enhanced by increased levels of tumour necrosis factor, interleukin 6 (IL-6), and hydroxycorticosteroids present in many patients with HIV lipodystrophy.
