Delay in sexual maturation in perinatally HIV-infected youths is mediated by poor growth.

ABSTRACT:

Objective

To evaluate the association between HIV infection and sexual maturation, and mediation of this association by HIV effects on growth.

Design

Pooled data were analyzed from two longitudinal cohort studies, the International Maternal Pediatric Adolescent AIDS Clinical Trials P219/219C Study (1993-2007) and the Pediatric HIV/AIDS Cohort Study Adolescent Master Protocol (2007-2015), including perinatally HIV-infected (PHIV) and HIV-exposed uninfected (PHEU) youths.

Methods

We evaluated age at sexual maturity among 2539 PHIV and PHEU adolescents based on annual physician-assessed pubertal staging measures. Interval-censored regression models were used to evaluate associations of HIV infection with age at maturity. Mediation analyses accounting for height and BMI Z-scores at specific ages were used to estimate direct and indirect effects of HIV infection on age at sexual maturity.

Results

Mean ages at sexual maturity for PHIV girls (n = 1032) were 15.5 years for both female breast and pubic hair and 15.9 and 15.8 years for PHIV boys (n = 1054) for genitalia and pubic hair, respectively. PHIV youths matured approximately 6 months later on average than PHEU (n = 221 girls and 232 boys), and this difference persisted after adjustment for race/ethnicity and birth cohort. BMI and height Z-scores mediated the association between HIV infection and later maturation in girls, accounting for up to 74% of the total HIV effect. Only height Z-scores mediated the effect of HIV on male age at maturity, accounting for up to 98% of the HIV effect.

Conclusion

PHIV youths attain sexual maturity later on average than PHEU youths. Much of this difference may be attributable to deficient growth, suggesting directions for future interventions.

Project description:ObjectiveThis study assessed impaired fasting glucose and associated factors among perinatally HIV-infected adolescents and youths in Dar es salaam Tanzania.BackgroundImpaired fasting glucose is a marker of heightened risk for developing type 2 diabetes among perinatally HIV-infected individuals. Therefore, identifying individuals at this stage is crucial to enable early intervention. Therefore, we assessed impaired fasting glucose (IFG) and associated factors among perinatally HIV-infected population in Dar es salaam Tanzania.MethodsA cross-sectional study was conducted among 152 adolescents and youth attending HIV clinic at Muhimbili National Hospital and Infectious Disease Centre from July to August 2020. Fasting blood glucose (>8 hours) was measured using one-touch selects LifeScan, CA, USA. We also examined C-Reactive Protein and interleukin-6 inflammatory biomarkers in relation to impaired fasting glucose (IFG). Associations between categorical variables were explored using Chi-square, and poison regression with robust variance was used to calculate the prevalence ratios.ResultsOf the 152 participants, the majority were male (n=83[54.6%]), and the median age was 15(14-18) years. Overweight or obesity was prevalent in 16.4%, while more than one in ten (13.2%) had high blood pressure (≥149/90mmHg). All participants were on antiretroviral therapy (ART); 46% had used medication for over ten years, and about one in three had poor medication adherence. Among the recruited participants, 29% had impaired fasting glucose. The odds of IFG were two times higher in males compared to females (PR, 2.07, 95% CI 1.19 -3.59 p=0.001). Moreover, we found with every increase of Interleukin 6 biomarker there was a 1.01 probability increase of impaired fasting glucose (PR, 1.01, 95% CI 1.00 - 1.02 p=0.003).ConclusionAbout one in three perinatally HIV-infected youths had impaired fasting glucose in Dar es Salaam, Tanzania, with males bearing the biggest brunt. Moreover, with every increase of 1.101 of the probability of having IFG increased. This calls for urgent measures to interrupt the progression to diabetes disease and prevent the dual burden of disease for this uniquely challenged population.

Project description:BackgroundSimilar to other young people with a chronic health condition, perinatally HIV-infected (PHIV) adolescents may have an impacted sexual development.ObjectivesThis paper aims to compare sexual milestones of PHIV to HIV uninfected peers, through a systematic review (SR) and explorative study.MethodsWe performed a systematic search in 4 electronic databases (Medline, Embase, Web of Science, and Scopus), according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Last search in all databases was performed in May 2021. We included studies that reported on quantitative data of any of the main outcomes and compared PHIV to HIV uninfected control groups. Main outcomes were defined as the occurrence and/or debut age of sexual milestones (falling in love, having been in a romantic relationship, masturbation, kissing, non-genital caressing (feeling or petting, touching), genital caressing (fingering, handjob), giving or receiving oral sex, and penetrative sex (vaginal or anal). We excluded case reports, audits, guidelines, editorials, abstracts, studies that reported on behaviorally infected HIV patients, studies that did not include an HIV uninfected control group and studies that could not be translated to English or Dutch. We used the Agency for Health Care Research and Quality (AHRQ) Checklist for quality assessment. We performed qualitative synthesis of the data. In the explorative study, we compared sexual milestones of PHIV and HIV uninfected controls matched for age, sex, ethnicity and educational level, using a subset of questions of a validated questionnaire.ResultsWe included eighteen studies in the SR, describing outcomes of an estimated 1,963 participants. Seventeen studies compared the occurrence and/or debut age of intercourse in PHIV and HIV uninfected controls and 4 studies reported on any of the other sexual milestones. The majority of studies found no difference in occurrence (12 of 16 studies) or debut age (6 of 8 studies) of intercourse in PHIV compared to controls. Two of 4 studies reporting on any of the other milestones found no significant differences between PHIV and HIV uninfected controls. In the explorative study, we included ten PHIV participants and 16 HIV uninfected, matched controls. PHIV tended to report a later debut age of sexual milestones than controls (not significant).Strengths and limitationsThe SR includes only a small number of studies and few studies report on non-penetrative milestones. The explorative study adds to this review by including non-penetrative milestones and comparing PHIV to HIV-uninfected, well-matched controls. However, the sample size was small.ConclusionPHIV seem to engage in sexual activities and achieve sexual milestones at a similar rate as their HIV uninfected peers, with a tendency of a later start in well treated PHIV. The review was registered in the PROSPERO database (CRD42021252103) and funded by AIDSfonds. AIDSfonds had no role in the study design or interpretations of this study. ter Haar AM, Fieten A, Van den Hof M, et al.

Project description:BackgroundIncreased incidence and prevalence of asthma have been documented for perinatally HIV-infected youth 10 to 21 years of age compared with HIV-exposed uninfected (HEU) youth.ObjectiveWe sought to perform objective pulmonary function tests (PFTs) in HIV-infected and HEU youth with and without diagnosed asthma.MethodAsthma was determined in 370 participants (218 HIV-infected and 152 HEU participants) by means of chart review and self-report at 13 sites. Interpretable PFTs (188 HIV-infected and 132 HEU participants) were classified as obstructive, restrictive, or normal, and reversibility was determined after bronchodilator inhalation. Values for HIV-1 RNA, CD4 and CD8 T cells, eosinophils, total IgE, allergen-specific IgE, and urinary cotinine were measured. Adjusted prevalence ratios (PRs) of asthma and PFT outcomes were determined for HIV-infected participants relative to HEU participants, controlling for age, race/ethnicity, and sex.ResultsCurrent asthma was identified in 75 (34%) of 218 HIV-infected participants and 38 (25%) of 152 HEU participants (adjusted PR, 1.33; P = .11). The prevalence of obstructive disease did not differ by HIV status. Reversibility was less likely in HIV-infected youth than in HEU youth (17/183 [9%] vs 21/126 [17%]; adjusted PR, 0.47; P = .020) overall and among just those with obstructive PFT results (adjusted PR, 0.46; P = .016). Among HIV-infected youth with current asthma, serum IgE levels were inversely correlated with CD8 T-cell counts and positively correlated with eosinophil counts and not associated with CD4 T-cell counts. HIV-infected youth had lower association of specific IgE levels to several inhalant and food allergens compared with HEU participants and significantly lower CD4/CD8 T-cell ratios (suggesting immune imbalance).ConclusionCompared with HEU youth, HIV-infected youth demonstrated decreased reversibility of obstructive lung disease, which is atypical of asthma. This might indicate an early stage of chronic obstructive pulmonary disease. Follow-up into adulthood is warranted to further define their pulmonary outcomes.
