Psychiatric disorders in perinatally HIV-exposed, uninfected children: a systematic review

The population of perinatally HIV-exposed but uninfected (HEU) children is growing rapidly globally. However, perinatal HIV and antiretroviral (ARV) medicine exposure in HIV-uninfected children has raised concerns about HEU children's mental well-being. The objective of this study was to systematically review the literature on psychiatric disorders in HEU children. The PRISMA guideline was used as a methodical frame of reference. A systematic search was conducted in 5 databases. Data from the included studies were extracted, and the results were summarized qualitatively. The search identified 1,976 articles of which 105 were eligible for full-text analysis. 13 studies met the inclusion criteria. Eight studies compared psychiatric disorder prevalence in perinatally HIV-infected children with HEU children, and only one study found a difference between the two groups. Three studies found that HEU children had a higher prevalence of psychiatric disorders compared with HIV-unexposed, uninfected (HUU) children. These findings indicate that factors such as psychosocial stress, socioeconomic status, and stigma contribute to the increased risk of mental disorders in HEU children. More research is needed comparing HEU children with HUU children adjusting for potential confounders that might partially explain the higher rates seen in the HIV-exposed population.Prospero ID: CRD42020212420.

Growing old with antiretroviral therapy or elderly people in antiretroviral therapy: two different profiles of comorbidity?

Background

In persons living with HIV (PLWH), the burden of non-communicable chronic diseases increased over time, because of aging associated with chronic inflammation, systemic immune activation, and long-term exposure to the combination antiretroviral therapy (ART).

Methods

To explore the association of chronological age, age at first ART, and exposure to ART with non-communicable chronic diseases, we performed a cross-sectional analysis to evaluate the prevalence of comorbidities in patients enrolled in the SCOLTA Project, stratified by groups of chronological age (50–59 and 60–69 years) and by years of antiretroviral treatment (ART, ≤ 3 or > 3 years).

Results

In 1394 subjects (23.8% women), mean age at enrollment was 57.4 (SD 6.5) years, and at first ART 45.3 (SD 10.7). Men were older than women both at enrollment (57.6 vs 56.8, p = 0.06) and at first ART (45.8 vs 43.6, p = 0.0009). ART duration was longer in women (13.1 vs 11.7 years, p = 0.01). The age- and sex-adjusted rate ratios (aRRs, and 95% confidence interval, CI) showed that longer ART exposure was associated with dyslipidemia (aRR 1.35, 95% CI 1.20–1.52), hypertension (aRR 1.52, 95% CI 1.22–1.89), liver disease (aRR 1.78, 95% CI 1.32–2.41), osteopenia/osteoporosis (aRR 2.88, 95% CI 1.65–5.03) and multimorbidity (aRR 1.36, 95% CI 1.21–1.54). These findings were confirmed in strata of age, adjusting for sex.

Conclusions

Our data suggest that longer ART exposure was associated with increased risk of dyslipidemia, hypertension, and osteopenia/osteoporosis, hence the presence of multimorbidity, possibly due to the exposition to more toxic antiretrovirals. We observed different comorbidities, according to ART exposure and age.

Cardiac remodeling and hypertension in HIV uninfected infants exposed in utero to antiretroviral therapy

BACKGROUND

We aimed to assess the postnatal pattern of cardiovascular remodeling associated with intrauterine exposure to maternal HIV and antiretroviral treatment (ART).

METHODS

Prospective cohort including 34 HIV-exposed uninfected (HEU) infants and 53 non-HIV-exposed infants evaluated from fetal life up to 6 months postnatally. A cardiovascular evaluation was performed including echocardiography, blood pressure and carotid intima media thickness (cIMT) measurement.

RESULTS

ART regimens during pregnancy included two nucleoside reverse transcriptase inhibitors (Abacavir+Lamivudine (32.4%), Emtricitabine+Tenofovir (41.2%) and Zidovudine+Lamivudine (20.6%)). At 6 months of age, HIV-exposed uninfected infants showed thicker myocardial walls (septal wall thickness mean 5.02 mm (SD 0.85) vs 3.98 mm (0.86); p<0.001) and relative systolic dysfunction with decreased mitral ring displacement (8.57 mm (2.03) vs 10.34 mm (1.84); p=0.002) and decreased tricuspid S' (9.71 cm/s (1.94) vs 11.54 cm/s (2.07); p=0.003) together with relative diastolic dysfunction showed by prolonged left isovolumic relaxation time (58.57 ms (13.79) vs 47.94 (7.39); p<0.001). Vascular assessment showed significantly higher systolic and diastolic blood pressure (102 mmHg (16.1) vs 80 mmHg (13.9); p<0.001 and 64 mmHg (14.4) vs 55 mmHg (10.2); p=0.045 respectively), with 50% of HIV-exposed children meeting criteria for hypertension vs 3.77% of the non-HIV-exposed group (p<0.001) and thicker mean cIMT in the HIV-exposed group (0.62 µm (0.09) vs 0.51 µm (0.09); p=0.015).

CONCLUSIONS

Subclinical cardiac impairment together with higher blood pressure and thicker cIMT were observed in HIV-exposed infants at 6 months of age. Half of them presented hypertension. Our findings support a possible increased cardiovascular risk in HIV uninfected infants exposed in utero to ART.

Acceptability of obtaining hair samples for assessing antiretroviral therapy (ART) exposure amongst alcohol drinking ART recipients in Tshwane, South Africa

To achieve the maximal therapeutic benefits of antiretroviral therapy (ART), high adherence is required. In South Africa, ART recipients are usually counselled by their health care providers to stop drinking alcohol, as heavy alcohol use compromises ART adherence. Patients who continue drinking alcohol tend to hide their alcohol-related adherence challenges from their health care providers. Objective measures of ART adherence/exposure may help to better identify drinkers who could benefit from ART adherence enhancement interventions. To evaluate the acceptability of collecting hair samples to objectively assess ART exposure among alcohol drinkers, we conducted four mixed-gender focus group discussions (FGDs) with alcohol drinking ART recipients at two ART sites in Tshwane, South Africa. Data were analysed using content analysis. ART recipients found hair sample testing for ART exposure to be novel and therefore expected that some ART recipients would initially be hesitant to provide a sample. Participants thought that the acceptability of hair sample collection could be enhanced by providing a full explanation of how the hair sample would be obtained and what the testing would entail. Participants also viewed hair sample testing as a viable and desirable alternative to blood sample testing for ART exposure. Some worries about the possible use of hair samples for witchcraft and the symbolic nature of hair were brought up, but these were not seen as insurmountable concerns. In conclusion, hair sample testing is a potentially acceptable method of assessing ART exposure amongst ART recipients who drink alcohol.
