Dolutegravir/Lamivudine Is Noninferior to Continuing Dolutegravir- and Non-Dolutegravir-Based Triple-Drug Antiretroviral Therapy in Virologically Suppressed People With Human Immunodeficiency Virus: DUALING Prospective Nationwide Matched Cohort Study.

Background: Confirming the efficacy of dolutegravir/lamivudine in clinical practice solidifies recommendations on its use. Methods: Prospective cohort study (DUALING) in 24 human immunodeficiency virus (HIV) treatment centers in the Netherlands. HIV RNA-suppressed cases were on triple-drug antiretroviral regimens without prior virological failure or resistance and started dolutegravir/lamivudine. Cases were 1:2 matched to controls on triple-drug antiretroviral regimens by the use of dolutegravir-based regimens, age, sex, transmission route, CD4+ T-cell nadir, and HIV RNA zenith. The primary endpoint was the treatment failure rate in cases versus controls at 1 year by intention-to-treat and on-treatment analyses with 5% noninferiority margin. Results: The 2040 participants were 680 cases and 1380 controls. Treatment failure in the 390 dolutegravir-based cases versus controls occurred in 8.72% and 12.50% (difference: -3.78% [95% confidence interval {CI}, -7.49% to .08%]) by intention-to-treat and 1.39% and 0.80% (difference: 0.59% [95% CI, -.80% to 1.98%]) by on-treatment analyses. The treatment failure risk in 290 non-dolutegravir-based cases was also noninferior to controls. Antiretroviral regimen modifications unrelated to virological failure explained the higher treatment failure rate by intention-to-treat. A shorter time on triple-drug antiretroviral therapy and being of non-Western origin was associated with treatment failure. Treatment failure, defined as 2 consecutive HIV RNA >50 copies/mL, occurred in 4 cases and 5 controls but without genotypic resistance detected. Viral blips occured comparable in cases and controls but cases gained more weight, especially when tenofovir-based regimens were discontinued. Conclusions: In routine care, dolutegravir/lamivudine was noninferior to continuing triple-drug antiretroviral regimens after 1 year, supporting the use of dolutegravir/lamivudine in clinical practice.

COVID-19 epidemiology and performance of the WHO clinical algorithm to diagnose COVID-19 in people with HIV from Ukraine.

BACKGROUND: The two main objectives were to evaluate the COVID-19 point prevalence and the test performance of the WHO case definition to diagnose COVID-19 clinically in people with HIV in West Ukraine. METHODS: Multicenter cross-sectional study in Lviv, Ukraine, from October 2020-November 2021. COVID-19 unvaccinated people with HIV were included regardless of COVID-19 symptoms at routine clinical visits and had standardized medical, quality of life (EQ(5D)) and SARS-CoV-2 serology assessments. Reported symptoms indicating potential COVID-19 events at inclusion or between March 2020 and inclusion were classified by the WHO case definition as suspected, probable or confirmed. A clinical COVID-19 case was defined as being SARS-CoV-2 seropositive with at least a suspected COVID-19 according to the WHO case definition. The primary endpoints were the clinical COVID-19 prevalence and the test characteristics of the WHO case definition with SARS-CoV-2 serology as reference. (Clinicaltrials.gov:NCT04711954). RESULTS: The 971 included people with HIV were median 40 years, 38.8% women, 44.8% had prior AIDS, and 55.6% had comorbidities. SARS-CoV-2 seroprevalence was 40.1% (95%CI:37.0-43.1) and 20.5% (95%CI:18.0-23.1) had clinical COVID-19 median 4 months (IQR:2-7) before inclusion. Clinical COVID-19 occurred less frequently in people with HIV with tuberculosis history, injecting drug use, CD4+ T-cells <200/mL and unemployment. The quality of life was not impacted after COVID-19. An at least probable COVID-19 classification by the WHO case definition had 44.1% sensitivity (95%CI:38.7-49.7), 85.2% specificity (95%CI:81.5-88.4), 66.6% positive predictive value (95%CI:59.8-73.0) and 69.5% negative predictive value (95%CI:65.5-73.3) to diagnose COVID-19. CONCLUSIONS: COVID-19 unvaccinated people with HIV from Ukraine had a significant COVID-19 rate and using the WHO case definition had insufficient diagnostic accuracy to diagnose these cases. The lower burden in vulnerable people with HIV was unexpected but might reflect a shielding effect.

Screening for tuberculosis infection and effectiveness of preventive treatment among people with HIV in low-incidence settings.

OBJECTIVE: To determine the yield of screening for latent tuberculosis infection (LTBI) among people with HIV (PWH) in low tuberculosis (TB) incidence countries (<10 TB cases per 100 000 persons). DESIGN: A systematic review and meta-analysis were performed to assess prevalence and predictive factors of LTBI, rate of TB progression, effect of TB preventive treatment (TPT), and numbers needed to screen (NNS). METHODS: PubMed and Cochrane Library were searched for studies reporting primary data, excluding studies on active or paediatric TB. We extracted LTBI cases, odds ratios, and TB incidences; pooled estimates using a random-effects model; and used the Newcastle-Ottawa scale for bias. RESULTS: In 51 studies with 65 930 PWH, 12% [95% confidence interval (CI) 10-14] had a positive LTBI test, which was strongly associated with origin from a TB-endemic country [odds ratio (OR) 4.7] and exposure to TB (OR 2.9). Without TPT (10 629 PWH), TB incidence was 28/1000 person-years (PY; 95% CI 12-45) for LTBI-test positive versus 4/1000 PY (95% CI 0-7) for LTBI-test-negative individuals. Among 625 PWH (1644 PY) receiving TPT, 15 developed TB (6/1000 PY). An estimated 20 LTBI-positive individuals would need TPT to prevent one case of TB, and numbers NNS to detect LTBI or prevent active TB varied according to a-priori risk of LTBI. CONCLUSION: The relatively high prevalence of LTBI among PWH and the strong correlation with origin from a TB-endemic country support risk-stratified LTBI screening strategies for PWH in low-incidence countries and treating those who test positive.

Impaired gut microbiota-mediated short-chain fatty acid production precedes morbidity and mortality in people with HIV.

Antiretroviral therapy (ART) has dramatically lengthened lifespan among people with HIV (PWH), but this population experiences heightened rates of inflammation-related comorbidities. HIV-associated inflammation is linked with an altered microbiome; whether such alterations precede inflammation-related comorbidities or occur as their consequence remains unknown. We find that ART-treated PWH exhibit depletion of gut-resident bacteria that produce short-chain fatty acids (SCFAs)-crucial microbial metabolites with anti-inflammatory properties. Prior reports establish that fecal SCFA concentrations are not depleted in PWH. We find that gut-microbiota-mediated SCFA production capacity is better reflected in serum than in feces and that PWH exhibit reduced serum SCFA, which associates with inflammatory markers. Leveraging stool and serum samples collected prior to comorbidity onset, we find that HIV-specific microbiome alterations precede morbidity and mortality in ART-treated PWH. Among these microbiome alterations, reduced microbiome-mediated conversion of lactate to propionate precedes mortality in PWH. Thus, gut microbial fiber/lactate conversion to SCFAs may modulate HIV-associated comorbidity risk.

No association between use of tenofovir disoproxil fumarate, etravirine, or integrase-strand transfer inhibitors and acquisition or severe outcomes of SARS-CoV-2 infection in people with HIV in the Netherlands.

In two Dutch observational cohorts of people with HIV, the use of TDF, ETR, or INSTIs was not independently associated with either the risk of incident SARS-CoV-2 infection or severe COVID-19 outcomes, as was suggested by previous observational and molecular docking studies. Our findings do not support a strategy of modifying antiretroviral therapy to include these agents to protect against SARS-CoV-2 infection and severe COVID-19 outcomes.

No evidence of rapid reversibility of tenofovir alafenamide and/or integrase strand transfer inhibitor-associated weight gain.

OBJECTIVE: We aimed to determine the reversibility of at least 7% weight gain within 12 months following tenofovir alafenamide (TAF) and/or integrase strand transfer inhibitor (INSTI) discontinuation in people with HIV (PWH) from the Dutch ATHENA cohort. DESIGN AND METHODS: PWH with at least 7% weight gain within 24 months after first switch to TAF and/or INSTI whilst being virally suppressed were selected, excluding those with comorbidities/co-medication known to be associated with weight gain. PWH who discontinued only TAF, only INSTI or TAF+INSTI, with available follow-up weight, were included. Mean weight change in the 24 months prior to and 12 months after discontinuation was modelled using mixed-effects linear regression. Factors associated with yearly weight change were assessed using linear regression. RESULTS: In 115 PWH, discontinuing only TAF ( n  = 39), only INSTI ( n  = 53) or TAF+INSTI ( n  = 23), the adjusted mean modelled weight change in the 24 months prior to discontinuation was +4.50 kg [95% confidence interval (CI) 3.04-6.10], +4.80 kg (95% CI 2.43-7.03) and +4.13 kg (95% CI 1.50-7.13), respectively, and -1.89 kg (95% CI -3.40 to -0.37), -1.93 kg (95% CI -3.92 to +0.07) and -2.55 kg (95% CI -5.80 to +0.02) in the 12 months postdiscontinuation. A greater number of years since HIV diagnosis was associated with greater reversibility of weight gain. No associations were found between weight change postdiscontinuation and changes in NRTI backbone or anchor agent at moment of discontinuation. CONCLUSION: There was no evidence of rapid reversibility of at least 7% TAF-associated and/or INSTI-associated weight gain after discontinuation of these agents. Studies of larger and more diverse populations of PWH are required to more fully understand the degree to which weight gain is reversible when discontinuing TAF and/or INSTI.

Biomarkers of central and peripheral inflammation mediate the association between HIV and depressive symptoms.

People living with HIV are at increased risk for depression, though the underlying mechanisms for this are unclear. In the general population, depression is associated with peripheral and central inflammation. Given this, and since HIV infection elicits inflammation, we hypothesised that peripheral and central inflammatory biomarkers would at least partly mediate the association between HIV and depressive symptoms. People living with HIV (n = 125) and without HIV (n = 79) from the COmorBidity in Relation to AIDS (COBRA) cohort were included in this study. Participants living with and without HIV had similar baseline characteristics. All participants living with HIV were on antiretroviral therapy and were virally suppressed. Plasma, CSF, and brain MR spectroscopy (MRS) biomarkers were measured. Using logistic regression models adjusted for sociodemographic factors, we found that participants with HIV were more likely to have Any Depressive Symptoms (Patient Health Questionnaire [PHQ-9] score >4) (odds ratio [95% confidence interval] 3.27 [1.46, 8.09]). We then sequentially adjusted the models for each biomarker separately to determine the mediating role of each biomarker, with a >10% reduction in OR considered as evidence of potential mediation. Of the biomarkers analysed, MIG (-15.0%) and TNF-α (-11.4%) in plasma and MIP1-α (-21.0%) and IL-6 (-18.0%) in CSF mediated the association between HIV and depressive symptoms in this sample. None of the other soluble or neuroimaging biomarkers substantially mediated this association. Our findings suggest that certain biomarkers of central and peripheral inflammation may at least partly mediate the relationship between HIV and depressive symptoms.

Robust Vaccine-Induced as Well as Hybrid B- and T-Cell Immunity across SARS-CoV-2 Vaccine Platforms in People with HIV.

Few studies have comprehensively compared severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine-induced and hybrid B- and T-cell responses in people with HIV (PWH) to those in comparable controls without HIV. We included 195 PWH and 246 comparable controls from the AGEhIV COVID-19 substudy. A positive nucleocapsid antibody (INgezim IgA/IgM/IgG) or self-reported PCR test defined prior SARS-CoV-2 infection. SARS-CoV-2 anti-spike (anti-S) IgG titers and anti-S IgG production by memory B cells were assessed. Neutralizing antibody titers were determined in a subset of participants. T-cell responses were assessed by gamma interferon (IFN-γ) release and activation-induced marker assay. We estimated mean differences in postvaccination immune responses (ß) between levels of determinants. Anti-S IgG titers and anti-S IgG production by memory B cells were not different between PWH and controls. Prior SARS-CoV-2 infection (ß = 0.77), receiving mRNA vaccine (ß = 0.56), female sex (ß = 0.24), fewer days between last vaccination and sampling (ß = 0.07), and a CD4/CD8 ratio of <1.0 (ß = -0.39) were independently associated with anti-S IgG titers, but HIV status was not. Neutralization titers against the ancestral and Delta and Omicron SARS-CoV-2 variants were not different between PWH and controls. IFN-γ release was higher in PWH. Prior SARS-CoV-2 infection (ß = 2.39), HIV-positive status (ß = 1.61), and fewer days between last vaccination and sampling (ß = 0.23) were independently associated with higher IFN-γ release. The percentages of SARS-CoV-2-reactive CD4+ and CD8+ T cells, however, were not different between PWH and controls. Individuals with well-controlled HIV generally mount robust vaccine-induced as well as hybrid B- and T-cell immunity across SARS-CoV-2 vaccine platforms similar to controls. Determinants of a reduced vaccine response were likewise largely similar in both groups and included a lower CD4/CD8 ratio. IMPORTANCE Some studies have suggested that people with HIV may respond less well to vaccines against SARS-CoV-2. We comprehensively compared B- and T-cell responses to different COVID-19 vaccines in middle-aged persons with well-treated HIV and individuals of the same age without HIV, who were also highly comparable in terms of demographics and lifestyle, including those with prior SARS-CoV-2 infection. Individuals with HIV generally mounted equally robust immunity to the different vaccines. Even stronger immunity was observed in both groups after prior SARS-CoV-2 infection. These findings are reassuring with respect to the efficacy of SARS-Cov-2 vaccines for the sizable and increasing global population of people with HIV with access and a good response to HIV treatment.

COVID-19 in people with HIV in the Netherlands.

OBJECTIVES: We investigated occurrence of and risk factors for severe COVID-19 outcomes in people with HIV (PWH) in the Netherlands. DESIGN: An ongoing prospective nationwide HIV cohort study. METHODS: COVID-19 diagnoses and outcomes with other relevant medical information were prospectively collected from electronic medical records in all HIV treatment centers in the Netherlands, from the start of the COVID-19 epidemic until December 31, 2021. Risk factors for COVID-19 related hospitalization and death were investigated using multivariable logistic regression, including demographics, HIV-related factors, and comorbidities. RESULTS: The cohort comprises 21 289 adult PWH, median age 51.2 years, 82% male, 70% were of Western origin, 12.0% were of sub-Saharan African and 12.6% Latin American/Caribbean origin, 96.8% had HIV-RNA less than 200 copies/ml, median CD4 + cell count 690 (IQR 510-908) cells/µl. Primary SARS-CoV-2 infections were registered in 2301 individuals, of whom 157 (6.8%) required hospitalization and 27 (1.2%) ICU admission. Mortality rates were 13 and 0.4% among hospitalized and nonhospitalized individuals, respectively. Independent risk factors for severe outcomes (COVID-19-related hospitalization and death) were higher age, having multiple comorbidities, a CD4 + cell count less than 200 cells/µl, uncontrolled HIV replication, and prior AIDS diagnosis. Migrants from sub-Saharan Africa, Latin America, and the Caribbean were at an increased risk of severe outcomes independently of other risk factors. CONCLUSION: In our national cohort of PWH, risk of severe COVID-19 outcomes was increased in individuals with uncontrolled HIV replication, low CD4 + cell count, and prior AIDS diagnosis, independently of general risk factors such as higher age, comorbidity burden and migrants originating from non-Western countries.

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.

Effect of the introduction of screening for cancer precursor lesions on anal cancer incidence over time in people living with HIV: a nationwide cohort study.

BACKGROUND: Incidence of anal cancer is high in people living with HIV, particularly in men who have sex with men (MSM). Screening for and treatment of precursor lesions might prevent progression to anal cancer in people living with HIV. We examined trends in incidence of and mortality after anal cancer diagnosis in people living with HIV, including the effect of screening from 2007 onwards, in the Netherlands. METHODS: In this observational cohort study, we analysed data from the ongoing open nationwide Dutch AIDS Therapy Evaluation in the Netherlands (ATHENA) cohort. We included all consenting adults living with HIV and identified all primary anal squamous cell carcinoma. We reported temporal trends in incident anal cancer cases from Jan 1, 1996, to Dec 31, 2020, and all-cause and anal cancer-related mortality in individuals diagnosed with anal cancer. Multivariable Poisson regression was used to explore risk factors for incident anal cancer and multivariable Cox regression was used to explore risk factors for anal cancer-related mortality. FINDINGS: Among 28 175 individuals in HIV care (59·7% MSM), 227 primary anal cancer cases were diagnosed. Despite the increasing average age of the cohort, crude incidence rates of anal cancer in MSM declined slowly over time, from 107·0 (95% CI 75·7-147·0) per 100 000 person-years in 1996-2005 to 93·7 (75·3-115·0) per 100 000 person-years in 2013-20 (p=0·49). Crude incidence rates in men who do not have sex with men (non-MSM) and women were generally lower than in MSM, but increased slightly over time, from 51·08 (95% CI 20·54-105·25) to 67·82 (40·83-105·91; p=0·52) per 100 000 person-years in non-MSM and from 8·09 (0·20-45·06) to 24·95 (10·03-51·40; p=0·29) per 100 000 person-years in women. The age-adjusted incidence rate in MSM in 2013-20 was significantly lower (rate ratio 0·62 [95% CI 0·41-0·92]) compared with in 1996-2005. Changes in risk factors (less smoking, cumulative exposure to CD4 count of <200 cells per µL, and plasma HIV-1 RNA of >1000 copies per mL) mostly explained the decrease in anal cancer risk over time in MSM. 3866 (23·0%) of 16 819 MSM participated in anal cancer screening at least once. TNM tumour staging was more favourable (Cochrane-Armitage test for trend p=0·033) in individuals diagnosed during screening. Crude anal cancer-associated 5-year mortality in people living with HIV decreased from 30·4% (1996-2005) to 18·3% (2013-20; odds ratio 0·48; p=0·070). Anal cancer-related mortality was 3·7% (95% CI 0·5-23·5) in all men who had been screened and 24·0% (95% CI 18·1-31·3) in men who had not been screened (p=0·023). In men, screening participation (hazard ratio [HR] 0·31, p=0·051) and cumulative exposure to CD4 counts of less than 200 cells per µL (HR 1·11 per year; p=0·0022) were independently associated with anal cancer-related mortality. INTERPRETATION: As anal cancer incidence is slowly declining in MSM but not in non-MSM and women, health-care professionals should not focus only on MSM for anal cancer prevention. Men diagnosed with anal cancer during screening had improved survival, probably because they were diagnosed at an earlier disease stage. Next to preventing anal cancer, these data are an important justification to screen those most at risk of anal cancer. FUNDING: None.

Long-Term Virological Treatment Outcomes in Adolescents and Young Adults With Perinatally and Non-Perinatally Acquired Human Immunodeficiency Virus.

Background: Long-term viral suppression on antiretroviral therapy (ART) is not established among all people with human immunodeficiency virus (PWH). Young adults (18-24 years) are recognized as a group vulnerable for suboptimal virological treatment outcomes. The aim of this study is to evaluate longitudinal virological treatment outcomes and to identify risk factors for virological failure (VF) among young adults with non-perinatally and perinatally acquired human immunodeficiency virus (HIV) in the Netherlands. Methods: We included individuals registered in the national ATHENA observational cohort from 2000 until 2020 who had entered care before the age of 25 years, who had received ART for at least 6 months with at least 2 available HIV ribonucleic acid measurements between the age of 18 and 24 years. We compared VF between age groups 12-17, 18-24, and 25-30 years. A multivariable generalized linear mixed model was used to evaluate risk factors for VF. Analyses were stratified by HIV acquisition mode. Results: In total, 1174 non-perinatally PWH and 157 perinatally PWH were included. In 2020, VF rate was 7% in non-perinatally PWH young adults and 19% in perinatally PWH young adults. The adjusted risk for VF was significantly higher in those aged 18-24 compared to 25-30 years in both non-perinatally PWH (odds ratio [OR], 1.27; 95% confidence interval [CI], 1.07-1.50) and perinatally PWH (OR, 2.34; 95% CI, 1.48-3.71). Conclusions: Young adulthood is a vulnerable period, with increased risk for VF, especially for perinatally PWH. The probability of VF decreased over time, but less for perinatally PWH compared to non-perinatally PWH.

One in 10 Virally Suppressed Persons With HIV in The Netherlands Experiences ≥10% Weight Gain After Switching to Tenofovir Alafenamide and/or Integrase Strand Transfer Inhibitor.

Background: We determined the frequency of and factors associated with ≥10% weight gain and its metabolic effects in virally suppressed people with human immunodeficiency virus (PWH) from the Dutch national AIDS Therapy Evaluation in the Netherlands (ATHENA) cohort switching to tenofovir alafenamide (TAF) and/or integrase strand transfer inhibitor (INSTI). Methods: We identified antiretroviral therapy-experienced but TAF/INSTI-naive PWH who switched to a TAF and/or INSTI-containing regimen while virally suppressed for >12 months. Individuals with comorbidities/comedication associated with weight change were excluded. Analyses were stratified by switch to only TAF, only INSTI, or TAF + INSTI. Factors associated with ≥10% weight gain were assessed using parametric survival models. Changes in glucose, lipids, and blood pressure postswitch were modeled using mixed-effects linear regression and compared between those with and without ≥10% weight gain. Results: Among 1544 PWH who switched to only TAF, 2629 to only INSTI, and 918 to combined TAF + INSTI, ≥10% weight gain was observed in 8.8%, 10.6%, and 14.4%, respectively. Across these groups, weight gain was more frequent in Western and sub-Saharan African females than Western males. Weight gain was also more frequent in those with weight loss ≥1 kg/year before switching, age <40 years, and those discontinuing efavirenz. In those with ≥10% weight gain, 53.7% remained in the same body mass index (BMI) category, while a BMI change from normal/overweight at baseline to obesity at 24 months postswitch was seen in 13.9%, 11.7%, and 15.2% of those switching to only TAF, only INSTI, and TAF + INSTI, respectively. PWH with ≥10% weight gain showed significantly larger, but small increases in glucose, blood pressure, and lipid levels. Lipid increases were limited to those whose switch included TAF, whereas lipids decreased after switching to only INSTI. Conclusions: Weight gain of ≥10% after switch to TAF and/or INSTI was common in virally suppressed PWH, particularly in females and those starting both drugs simultaneously. Consequent changes in metabolic parameters were, however, modest.

Similar Risk of Severe Acute Respiratory Syndrome Coronavirus 2 Infection and Similar Nucleocapsid Antibody Levels in People With Well-Controlled Human Immunodeficiency Virus (HIV) and a Comparable Cohort of People Without HIV.

BACKGROUND: Within the ongoing AGEhIV Cohort Study in Amsterdam, we prospectively compared the incidence of and risk factors for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection between human immunodeficiency virus (HIV)-positive and HIV-negative participants. Moreover, we compared SARS-CoV-2 nucleocapsid antibody levels between participants with incident infection from both groups. METHODS: Starting in September 2020, consenting HIV-positive and HIV-negative participants were assessed every 6 months for incident SARS-CoV-2 infection, using combined immunoglobulin (Ig) A/IgM/IgG SARS-CoV-2 nucleocapsid antibody assay. Cumulative incidence of SARS-CoV-2 infection and associated risk factors were assessed from 27 February 2020 through 30 April 2021, using complementary log-log regression. In those with incident SARS-CoV-2 infection, nucleocapsid (N) antibody levels were compared between groups using linear regression. RESULTS: The study included 241 HIV-positive (99.2% virally suppressed) and 326 HIV-negative AGEhIV participants. The cumulative SARS-CoV-2 incidence by April 2021 was 13.4% and 11.6% in HIV-positive and HIV-negative participants, respectively (P = .61). Younger age and African origin were independently associated with incident infection. In those with incident infection, only self-reported fever, but not HIV status, was associated with higher N antibody levels. CONCLUSIONS: HIV-positive individuals with suppressed viremia and adequate CD4 cell counts had similar risk of SARS-CoV-2 acquisition and similar SARS-CoV-2 N antibody levels after infection compared with a comparable HIV-negative cohort. CLINICAL TRIAL REGISTRATION: NCT01466582.

Normal structural brain development in adolescents treated for perinatally acquired HIV: a longitudinal imaging study.

OBJECTIVE: Cross-sectional studies, including one from our NOVICE cohort [Neurological Visual and Cognitive performance in children with treated perinatally acquired HIV (PHIV) compared with matched HIV-negative controls], have revealed that the brains of children with PHIV have lower white matter and grey matter volumes, more white matter hyperintensities (WMH) and poorer white matter integrity. This longitudinal study investigates whether these differences change over time. METHODS: We approached all NOVICE participants to repeat MRI after 4.6 ±â€Š0.3 years, measuring total white matter and grey matter volume, WMH volume and white matter integrity, obtained by T1-weighted, fluid-attenuated inversion recovery (FLAIR) and diffusion tensor imaging (DTI), respectively. We compared rates of change between groups using multivariable linear mixed effects models, adjusted for sex and age at enrolment. We investigated determinants of developmental deviation, and explored associations with cognitive development. RESULTS: Twenty out of 31 (65%) PHIV-positive, and 20 out of 37 (54%) HIV-negative participants underwent follow-up MRI. Groups did not significantly differ in terms of age and sex. Over time, we found no statistically different changes between groups for white matter and WMH volumes, and for white matter integrity (P > 0.1). Total grey matter volume decreased significantly less in PHIV [group∗time 10 ml, 95% confidence interval -1 to 20, P = 0.078], but this difference in rate of change lost statistical significance after additional adjustment for height (group∗time 9 ml, 95% confidence interval -2 to 20, P = 0.112). We found no HIV-associated determinants for potential reduced grey matter pruning, nor associations with cognitive development. CONCLUSION: While using long-term antiretroviral treatment, structural brain development of adolescents growing up with perinatally acquired HIV appears largely normal.

Differences in location of cerebral white matter hyperintensities in children and adults living with a treated HIV infection: A retrospective cohort comparison.

Cerebral white matter hyperintensities (WMH) persist in children and adults living with HIV, despite effective combination antiretroviral therapy (cART). As age and principal routes of transmission differ between children (perinatally) and adults (behaviorally), comparing the characteristics and determinants of WMH between these populations may increase our understanding of the pathophysiology of WMH. From separate cohorts of 31 children (NOVICE) and 74 adults (AGEhIV), we cross-sectionally assessed total WMH volume and number of WMH per location (periventricular vs. deep) using fluid-attenuated inversion recovery (FLAIR) MRI images. WMH were either periventricular when within 10mm of the lateral ventricles, or deep otherwise. We assessed patient- or HIV-related determinants of total WMH volume (adjusted for intracranial volume) and location of WMH using logistic regression, while stratifying on children and adults. At enrollment, median age of participants was 13.8 years (IQR 11.4-15.9) for children and 53.4 years (IQR 48.3-60.8) for adults and 27/31 children (87%) and 74/74 adults (100%) had an HIV RNA viral load <200 copies/mL. WMH were present in 16/27 (52%) children and 74/74 adults (100%). The prevalence of deep WMH was not different between groups, (16/16 [100%] in children vs. 71/74 [96%] in adults, p = 0,999), yet periventricular WMH were more prevalent in adults (74/74 [100%]) compared to children (9/16; 56%) (p<0.001). Median WMH volume was higher in adults compared to children (1182 mm3 [425-2617] vs. 109 mm3 [61.7-625], p<0.001). In children, boys were more likely to have deep WMH compared to girls. In adults, older age was associated with higher total WMH volume, and age, hypertension and lower CD4+ T-lymphocyte nadir with a higher number of periventricular WMH. Our findings suggest that the location of WMH differs between children and adults living with HIV, hinting at a different underlying pathogenesis.

Cause-specific mortality after diagnosis of cancer among HIV-positive patients: A collaborative analysis of cohort studies.

People living with HIV (PLHIV) are more likely than the general population to develop AIDS-defining malignancies (ADMs) and several non-ADMs (NADMs). Information is lacking on survival outcomes and cause-specific mortality after cancer diagnosis among PLHIV. We investigated causes of death within 5 years of cancer diagnosis in PLHIV enrolled in European and North American HIV cohorts starting antiretroviral therapy (ART) 1996-2015, aged ≥16 years, and subsequently diagnosed with cancer. Cancers were grouped: ADMs, viral NADMs and nonviral NADMs. We calculated cause-specific mortality rates (MR) after diagnosis of specific cancers and compared 5-year survival with the UK and France general populations. Among 83,856 PLHIV there were 4,436 cancer diagnoses. Of 603 deaths after ADM diagnosis, 292 (48%) were due to an ADM. There were 467/847 (55%) and 74/189 (39%) deaths that were due to an NADM after nonviral and viral NADM diagnoses, respectively. MR were higher for diagnoses between 1996 and 2005 versus 2006-2015: ADMs 102 (95% CI 92-113) per 1,000 years versus 88 (78-100), viral NADMs 134 (106-169) versus 111 (93-133) and nonviral NADMs 264 (232-300) versus 226 (206-248). Estimated 5-year survival for PLHIV diagnosed with liver (29% [19-39%]), lung (18% [13-23%]) and cervical (75% [63-84%]) cancer was similar to general populations. Survival after Hodgkin's lymphoma diagnosis was lower in PLHIV (75% [67-81%]). Among ART-treated PLHIV diagnosed with cancer, MR and causes of death varied by cancer type, with mortality highest for liver and lung cancers. Deaths within 5 years of NADM diagnoses were more likely to be from cancer than AIDS.

Neurocognitive Development in Perinatally Human Immunodeficiency Virus-infected Adolescents on Long-term Treatment, Compared to Healthy Matched Controls: A Longitudinal Study.

BACKGROUND: A cross-sectional analysis of the Neurological, cOgnitive and VIsual performance in hiv-infected Children cohort showed significant cognitive impairment in combination antiretroviral therapy (cART)-treated, perinatally human immunodeficiency virus (HIV)-infected adolescents (PHIV+) compared to age-, sex-, ethnicity- and socioeconomic status (SES)-matched HIV-negative controls (HIV-). In this longitudinal study, we compared cognitive development in the same adolescents over time. METHODS: We repeated the standardized cognitive test battery after a mean of 4.6 years (standard deviation 0.3). In participants who completed both assessments, we compared cognitive trajectories between groups in the domains of intelligence quotient (IQ), processing speed, working memory, executive functioning, learning ability, and visual-motor function, using linear mixed models. We explored associations with disease- and treatment-related factors and used multivariate normative comparison (MNC) to determine the prevalence of cognitive impairment. RESULTS: There were 21 PHIV+ and 23 HIV- participants that completed 2 assessments and were similar concerning age, sex, ethnicity, and SES. Compared to HIV- participants, in PHIV+ participants the IQ score increased significantly more over time (group*time 6.01, 95% confidence interval [CI] 1.5-10.50; P = .012), whereas executive functioning decreased significantly more (group*time -1.43 z score, 95% CI -2.12 to -0.75; P < .001), resulting in the disappearance and appearance of significant differences. Processing speed, working memory, learning ability, and visual-motor function trajectories were not statistically different between groups. Univariately, those who had started cART at an older age deviated more in executive functioning (-0.13 z score, 95% CI -0.24 to -0.02; P = .043). The prevalence of cognitive impairments by MNC was similar in both groups, at both time points. CONCLUSIONS: The cART-treated PHIV+ adolescents appeared to have similar global cognitive development, compared to their healthy peers. Executive functioning trajectory appears to deviate, potentially explained by earlier brain damage.

Incidence and Risk Factors for Invasive Pneumococcal Disease and Community-acquired Pneumonia in Human Immunodeficiency Virus-Infected Individuals in a High-income Setting.

BACKGROUND: Although people living with human immunodeficiency virus (PLWH) are at increased risk of invasive pneumococcal disease (IPD) and community-acquired pneumonia (CAP), it is unclear whether this remains the case in the setting of early initiation of combination antiretroviral therapy (cART), at high CD4 cell counts. This is important, as pneumococcal vaccination coverage in PLWH is low in Europe and the United States, despite longstanding international recommendations. METHODS: We identified all CAP and IPD cases between 2008 and 2017 in a cohort of PLWH in a Dutch HIV referral center. We calculated incidence rates stratified by CD4 count and cART status and conducted a case-control study to identify risk factors for CAP in PLWH receiving cART. RESULTS: Incidence rates of IPD and CAP in PLWH were 111 and 1529 per 100 000 patient-years of follow-up (PYFU). Although IPD and CAP occurred more frequently in patients with CD4 counts <500 cells/µL (incidence rate ratio [IRR], 6.1 [95% confidence interval, 2.2-17] and IRR, 2.4 [95% confidence interval, 1.9-3.0]), the incidence rate in patients with CD4 counts >500 cells/µL remained higher compared with the general population (946 vs 188 per 100 000 PYFU). All IPD isolates were vaccine serotypes. Risk factors for CAP were older age, CD4 counts <500 cells/µL, smoking, drug use, and chronic obstructive pulmonary disease. CONCLUSIONS: The incidence of IPD and CAP among PLWH remains higher compared with the general population, even in those who are virally suppressed and have high CD4 counts. With all serotyped IPD isolates covered by pneumococcal vaccines, our study provides additional argumentation against the poor current adherence to international recommendations to vaccinate PLWH.

Longitudinal virological outcomes and factors associated with virological failure in behaviorally HIV-infected young adults on combination antiretroviral treatment in the Netherlands, 2000 to 2015.

Achieving and maintaining viral suppression in young adults (18-24 years) living with HIV is challenging. Overall HIV viral suppression rates are lower in young as compared to older adults. Longitudinal data provide valuable insight on dynamics of viral suppression and variables of potential influence on HIV virological failure (VF), but is scarce in young adults living with HIV on combination antiretroviral therapy (cART). We evaluated longitudinal virological outcomes of behaviorally young adults (18-24 years) living with HIV in the Netherlands over a period of 15 years.We analyzed data from the Dutch national HIV database of 816 young adults living with HIV on cART in the Netherlands from 2000 to 2015. VF was defined as 2 consecutive detectable plasma HIV-1 viral load (VL) measurements > 200 copies/ml. Generalized linear mixed model analyses were used to assess HIV VF over time and identify risk factors associated with VF.VF during the study follow-up occurred at least once in 26% of cases. The probability of experiencing VF decreased over the study period per calendar year (OR 0.78, 95% confidence interval [CI];0.72; 0.85). Factors significantly associated with VF were being infected through heterosexual contact (OR 5.20, CI 1.39;19.38) and originating from Latin America or the Caribbean (OR 6.59, CI 2.08;20.92). Smaller, yet significant risk factors for VF were being infected through a blood transfusion or a needle accident (OR9.93, CI 1.34;73.84, and having started with cART with a nadir CD4 count >500 cells/µl (OR 11.36, CI 2.03;63.48).In our large cohort of young adults, the risk of VF has diminished over 15 years. Specific subgroups were identified to be at risk for suboptimal treatment.
