RESUMO

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.

RESUMO

Background: Little is known about the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron infection in people with human immunodeficiency virus (HIV; PWH) with vaccine-induced or hybrid immunity. We assessed the incidence of Omicron infection in 209 AGEhIV coronavirus disease 2019 substudy participants with well-controlled HIV on antiretroviral therapy and 280 comparable controls, who had received at least the primary vaccination series. Methods: From September 2020 onward, participants were assessed every 6 months for the incidence of SARS-CoV-2 infection, per SARS-CoV-2 nucleocapsid antibody assay or self-reported positive antigen or polymerase chain reaction test. Between 1 January and 31 October 2022, the cumulative incidence of Omicron infection and associated risk factors were estimated using a conditional risk-set Cox proportional hazards model. Results: The cumulative incidence of a first Omicron infection was 58.3% by 31 October 2022, not significantly different between groups. HIV status was not independently associated with acquiring Omicron infection. Former and current smoking, as well as an increased predicted anti-spike immunoglobulin G titer were significantly associated with a lower risk of Omicron infection. The majority of infections were symptomatic, but none required hospitalization. Conclusions: People with well-controlled HIV and controls in our cohort experienced a similarly high proportion of Omicron infections. More booster vaccinations significantly reduced the risk of infection. Clinical Trial Registration. NCT01466582.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: People with HIV generally have more ageing-associated comorbidities than those without HIV. We aimed to establish whether the difference in comorbidities and their disease burden changes with ageing. METHODS: In this prospective, longitudinal cohort study, we assessed comorbidities commonly associated with ageing every 2 years in 596 HIV-positive and 550 HIV-negative participants. HIV-positive participants were recruited from the HIV outpatient clinic of the Amsterdam University Medical Centres (Amsterdam, Netherlands). HIV-negative participants were recruited from the sexual health clinic and the Amsterdam Cohort Studies at the Public Health Service of Amsterdam (Amsterdam, Netherlands). Inclusion criteria were participants aged 45 years or older and, for HIV-negative participants, a documented HIV-negative antibody test. The mean number of comorbidities present over time was compared between groups by use of Poisson regression, accounting for dropout and death through joint survival models. Mean disability-adjusted life-years (DALYs) accrued during 2-year intervals were compared between groups by use of an exponential hurdle model. FINDINGS: Between Oct 29, 2010, and Oct 9, 2012, participants were enrolled and then prospectively followed up until their last visit before Oct 1, 2018. 1146 participants were followed up for a median 5·9 years (IQR 5·7-6·0), during which 231 participants (20·2%) dropped out: 145 (24·3%) of 596 HIV-positive and 86 (15·6%) of 550 HIV-negative. 38 (3·3%) of 1146 participants died: 31 (5·2%) of 596 HIV-positive and seven (1·3%) of 550 HIV-negative. 24 HIV-positive and two HIV-negative participants died from ageing-associated comorbidities. 15 HIV-positive participants versus one HIV-negative participant died from non-AIDS malignancies. At inclusion, mean number of comorbidities was higher in HIV-positive participants (0·65) than in HIV-negative participants (0·32; p<0·0001). Mean number of comorbidities increased at similar rates over time: rate ratio (RR) per year for HIV-positive participants 1·04 (95% CI 1·00-1·08), RR per year for HIV-negative participants 1·05 (1·01-1·08; pinteraction=0·78). Number of comorbidities was associated with an increased risk of death (hazard ratio 3·33 per additional comorbidity, 95% CI 2·27-4·88; p<0·0001). HIV-positive participants had higher increases in mean DALYs than HIV-negative participants (0·209 per year, 95% CI 0·162-0·256 vs 0·091 per year, 0·025-0·157; pinteraction=0·0045). This difference was reduced when deaths were excluded in establishing DALYs (0·127, 0·083-0·171 vs 0·066, 0·005-0·127; pinteraction =0·11). INTERPRETATION: The larger comorbidity prevalence in HIV-positive participants aged 50-55 years on effective antiretroviral treatment than in HIV-negative participants increased similarly as participants aged and was associated with an increased risk of death, particularly of non-AIDS malignancies. Our findings reinforce the need for strategies to optimise prevention, screening, and early intervention.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Little is known about the impact of social distancing on health-related quality of life and depressive symptoms in older people with HIV during the COVID-19 pandemic. SETTING: HIV-positive and HIV-negative AGEhIV Cohort Study participants. METHOD: In September-November 2020, participants completed questionnaires on social distancing, change in substance use, health-related quality of life (EQ-6D, including EQ-VAS), and depressive symptoms (PHQ-9). Associations between social distancing and (1) EQ-VAS or (2) PHQ-9 score ≥10 (clinically relevant depressive symptoms) were analyzed using fractional and binomial logistic regression, respectively. RESULTS: Two hundred fourteen HIV-positive and 285 HIV-negative participants were analyzed. 77.4% found social distancing important and 66.9% reported good adherence to these measures, without significant differences between HIV-positive and HIV-negative participants. In both groups, &lt;5% reported increased smoking or recreational drug use, but more HIV-positive (12.2%) than HIV-negative (4.9%) participants (P = 0.005) reported increased/more frequent alcohol use. Median EQ-VAS was slightly lower in HIV-positive (80 IQR = 73-90) than HIV-negative (84 IQR = 75-90) participants (P = 0.041). The prevalence of clinically relevant depressive symptoms was similar (HIV-positive, 8.4% and HIV-negative, 8.8%). Worrying about contracting COVID-19 and having ≥3 (vs no) comorbidities were associated with lower EQ-VAS and finding social distancing easy with higher EQ-VAS. Worrying about contracting COVID-19 and younger than 60 years (vs ≥65) were associated with higher odds of clinically relevant depressive symptoms. HIV status was associated with neither outcome. CONCLUSIONS: Initially during the COVID-19 pandemic in the Netherlands, a similar majority of HIV-positive and HIV-negative participants reported adhering to social distancing. Irrespective of HIV status, concerns about contracting COVID-19 negatively affected participants' perceived current health and increased risk of depressive symptoms.

RESUMO

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.
