The Impact of the COVID-19 Pandemic on Stress, Isolation, Smoking Behaviors, and Motivation to Quit in People with HIV Who Smoke.

People with HIV (PWH) smoke at higher rates compared with the general population and have lower cessation rates. The primary aim of this study was to examine the impact of the COVID-19 pandemic on smoking in PWH. A survey was administered to participants in two smoking cessation trials in the United States. Mean cigarettes per day was 13.9 (SD 8.6), and participants reported they had smoked on average for 30.93 years (SD 10.4). More than half (55.7%) of participants (N = 140) reported not changing their smoking during the pandemic, while 15% reported decreasing, and 25% reported increasing their smoking. In bivariate analyses, worrying about food due to lack of money (χ2 = 9.13, df 2, p = 0.01) and greater Covid-related worry (rs = 0.19, p = 0.02) were significantly associated with increased smoking. Qualitative research may be needed to more clearly elucidate factors related to smoking behaviors among PWH.

People aging with HIV - protecting a population vulnerable to effects of COVID-19 and its control measures.

Certain comorbidities known to increase the risk of poor outcomes in COVID-19 exist at higher rates in people with HIV; people aging with HIV (PAWH) face additional risk due to the association of advanced age with COVID-19 mortality. Cognitive and functional deficits and social barriers have been identified in cohorts of people aging with HIV. It is postulated that the COVID-19 pandemic potentially threatens PAWH disproportionately to the general population, both in mortality risk due to age and comorbidities, and in potential deleterious effects of policies that seek to drastically limit in-person interaction and access to healthcare systems. A description of and preliminary data from a demonstration project to improve geriatric assessments of people with HIV over age 50 in an urban HIV clinic are presented, in support of this theory. Advice is offered on key strategies utilized to continue to provide care to PAWH during the COVID-19 pandemic, including transition to telemedicine, vaccination, revision of staff roles, repurposing of funding, and a new reliance on available local resources.

Evaluating virological outcomes in people with HIV on stable antiretroviral therapy with reduced frequency of HIV viral load monitoring during the COVID-19 pandemic.

OBJECTIVES: In response to the COVID-19 pandemic, HIV outpatient attendances were restricted from March 2020, resulting in reduced frequency of HIV viral load (VL) monitoring (previously 6-monthly) in clinically stable and virologically suppressed people living with HIV (PLWH). We investigated virological outcomes during this period of reduced monitoring and compared with the previous year, prior to the COVID-19 pandemic. METHODS: People living with HIV with undetectable VL (<200 HIV RNA copies /mL) on antiretroviral therapy (ART) were identified from March 2018 to February 2019. We determined VL outcomes during the pre-COVD-19 period (March 2019-February 2020) and the COVID-19 period (March 2020-February 2021) when monitoring was restricted. Frequency and longest durations between VL tests in each period were evaluated, and virological sequelae in those with detectable VL were determined. RESULTS: Of 2677 PLWH virologically suppressed on ART (March 2018-February 2019), VLs were measured and undetectable in 2571 (96.0%) and 2003 (77.9%) in the pre-COVID and COVID periods, respectively. Mean (SD) numbers of VL tests were 2.3 (1.08) and 1.1 (0.83) and mean longest duration between VL tests was 29.5 weeks (SD 8.25, 3.1% were ≥12 months) and 43.7 weeks (12.64, 28.4% were ≥12 months), in the pre-COVID and COVID periods, respectively. Of 45 individuals with one or more detectable VL during the COVID-19 period, two developed new drug resistance mutations. CONCLUSION: Reduced VL monitoring was not associated with poorer virological outcomes in the majority of stable individuals receiving ART. One in 20 individuals had not returned for VL testing after ≥31 months and the risk of harm in these individuals is unknown.

Booster vaccination against SARS-CoV-2 induces potent immune responses in people with HIV.

BACKGROUND: People with HIV on antiretroviral therapy with good CD4 T cell counts make effective immune responses following vaccination against SARS-CoV-2. There are few data on longer term responses and the impact of a booster dose. METHODS: Adults with HIV were enrolled into a single arm open label study. Two doses of ChAdOx1 nCoV-19 were followed twelve months later by a third heterologous vaccine dose. Participants had undetectable viraemia on ART and CD4 counts >350 cells/µl. Immune responses to the ancestral strain and variants of concern were measured by anti-spike IgG ELISA, MesoScale Discovery (MSD) anti-spike platform, ACE-2 inhibition, Activation Induced Marker (AIM) assay and T cell proliferation. FINDINGS: 54 participants received two doses of ChAdOx1 nCoV-19. 43 received a third dose (42 with BNT162b2; 1 with mRNA-1273) one year after the first dose. After the third dose, total anti-SARS-CoV-2 spike IgG titres (MSD), ACE-2 inhibition and IgG ELISA results were significantly higher compared to Day 182 titres (P < 0.0001 for all three). SARS-CoV-2 specific CD4+ T cell responses measured by AIM against SARS-CoV-2 S1 and S2 peptide pools were significantly increased after a third vaccine compared to 6 months after a first dose, with significant increases in proliferative CD4 + and CD8+ T cell responses to SARS-CoV-2 S1 and S2 after boosting. Responses to Alpha, Beta, Gamma, and Delta variants were boosted, although to a lesser extent for Omicron. CONCLUSIONS: In PWH receiving a third vaccine dose, there were significant increases in B and T cell immunity, including to known VOCs.

Booster shot of inactivated SARS-CoV-2 vaccine induces potent immune responses in people living with HIV.

This study aimed to investigate the immunogenicity to SARS-CoV-2 and evasive subvariants BA.4/5 in people living with HIV (PLWH) following a third booster shot of inactivated SARS-CoV-2 vaccine. We conducted a cross-sectional study in 318 PLWH and 241 healthy controls (HC) using SARS-CoV-2 immunoassays. Vaccine-induced immunological responses were compared before and after the third dose. Serum levels of IgG anti-RBD and inhibition rate of NAb were significantly elevated at the "post-third dose" sampling time compared with the pre-third dose in PLWH, but were relatively decreased in contrast with those of HCs. Induced humoral and cellular responses attenuated over time after triple-dose vaccination. The neutralizing capacity against BA.4/5 was also intensified but remained below the positive inhibition threshold. Seropositivity of SARS-CoV-2-specific antibodies in PLWH was prominently lower than that in HC. We also identified age, CD4 cell counts, time after the last vaccination, and WHO staging type of PLWH as independent factors associated with the seropositivity of antibodies. PLWH receiving booster shot of inactivated vaccines generate higher antibody responses than the second dose, but lower than that in HCs. Decreased anti-BA.4/5 responses than that of WT impede the protective effect of the third dose on Omicron prevalence.

A Systematic Review of COVID-19 Vaccine Antibody Responses in People With HIV.

HIV infection is a significant independent risk factor for severe coronavirus disease 2019 (COVID-19) disease and death. We summarize COVID-19 vaccine responses in people with HIV (PWH). A systematic literature review of studies from January 1, 2020, to March 31, 2022, of COVID-19 vaccine immunogenicity in PWH from multiple databases was performed. Twenty-eight studies from 12 countries were reviewed. While 22 (73%) studies reported high COVID-19 vaccine seroconversion rates in PWH, PWH with lower baseline CD4 counts, CD4/CD8 ratios, or higher baseline viral loads had lower seroconversion rates and immunologic titers. Data on vaccine-induced seroconversion in PWH are reassuring, but more research is needed to evaluate the durability of COVID-19 vaccine responses in PWH.

Limited Humoral and Specific T-Cell Responses After SARS-CoV-2 Vaccination in PWH With Poor Immune Reconstitution.

BACKGROUND: We analyzed humoral and cellular immune responses induced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) messenger RNA (mRNA) vaccines in people with human immunodeficiency virus (HIV; PWH) who had CD4+ T-cell counts <200/µL (HIV<200 group). METHODS: This prospective cohort study included 58 PWH in the HIV<200 group, 36 with CD4+ T-cell counts >500/µL (HIV>500 group), and 33 HIV-1-negative controls (control group). Antibodies against the SARS-CoV-2 spike protein (anti-S immunoglobulin [Ig] G) and the receptor-binding domain (anti-RBD IgG) were quantified before and 4 weeks after the first and the second doses of BNT162b2 or mRNA-1273 (at week 8). Viral neutralization activity and T-cell responses were also determined. RESULTS: At week 8, anti-S/anti-RBD IgG responses increased in all groups (P < .001). Median (interquartile range) anti-S and anti-RBD IgG levels at week 8 were 153.6 (26.4-654.9) and 171.9 (61.8-425.8) binding antibody units (BAU)/mL, respectively, in the HIV<200 group, compared with 245.6 (145-824) and 555.8 (166.4-1751) BAU/mL in the HIV>500 group and 274.7 (193.7-680.4) and 281.6 (181-831.8) BAU/mL in controls (P < .05). Neutralizing capacity and specific T-cell immune responses were absent or reduced in 33% of those in the HIV<200 group, compared with 3.7% in the HIV>500 group (P < .01). CONCLUSIONS: One-third of PWH with CD4+ T-cell counts <200/µL show low anti-S/anti-RBD IgG levels, reduced in vitro neutralization activity against SARS-CoV-2, and no vaccine-induced T cells after receiving coronavirus disease 2019 mRNA vaccines.

Willingness to Be Vaccinated Against COVID-19 Among People With HIV in the United States: Results From a National Survey.

Background: Approximately 215 million Americans have been fully vaccinated for COVID-19, representing over 65% of the total population. People with HIV (PWH) may be more susceptible to COVID-19 infection or severe disease, elevating the importance of COVID-19 vaccination uptake in the population. We report results from a national survey of PWH to evaluate the likelihood of receiving a COVID-19 vaccine. Methods: We conducted an online survey of 1,030 PWH living in the United States between December 6, 2020 and January 8, 2021 to evaluate likelihood of receiving a COVID-19 vaccine. Results: Overall, participants were highly willing to be vaccinated, with 83.8% stating they "strongly agree" (65.7%) or "somewhat agree" (18.1%). Participants' top vaccine-related concerns were side-effects (39.3%), safety (14.7%), and fair/equitable distribution of the vaccine to affected communities (13.6%). Participants were more willing to be vaccinated if they reported receiving an annual influenza vaccination (p < 0.001), had previously tested positive for (p = 0.043) COVID-19, had been hospitalized for (p = 0.027) COVID-19 infection, or had an undetectable HIV viral load (p = 0.002). Black (p < 0.001), politically conservative (p < 0.001), and participants with an annual income of ≤ $19,999 (p = 0.005) were significantly less willing to be vaccinated for COVID-19. Conclusions: The vast majority of PWH were willing to be vaccinated, though predominantly those who were already engaged in HIV care or directly affected by COVID-19. Findings from this large survey of PWH suggest intensive outreach efforts are needed to support engagement in vaccination programs, particularly among Black and politically conservative PWH.

COVID-19 Vaccine Hesitancy and Associated Factors among People with HIV in the United States: Findings from a National Survey.

INTRODUCTION: Scaling up vaccination against COVID-19 is central to controlling the COVID-19 epidemic in the United States. Several vaccines are now approved for the prevention of COVID-19, but public concerns over safety and efficacy have heightened distrust and vaccine hesitancy. This is particularly concerning among people with HIV (PWH) who may be vulnerable to more severe COVID-19 disease. Here, we aimed to identify and understand COVID-19 vaccine hesitancy in a sample of PWH in the U.S. METHODS: We conducted a cross-sectional online survey among PWH in the U.S. between 6 December 2020 and 8 January 2021. Measures included demographics, participants' HIV and health-related attributes, COVID-19 history and experiences, COVID-19 vaccine-related concerns, and standardized measures of attitudes towards COVID-19 vaccines. Multivariate linear regression was used to identify factors associated with vaccine hesitancy in this sample. RESULTS: Among the 1030 respondents, most were male (89.7%), White (66.0%), and identified as gay or lesbian (84.5%). Participants' mean time living with HIV was 17.0 years (standard deviation (SD) = 11.1). The mean score for vaccine hesitancy was 1.5 (SD = 0.5; range: 1-5); 935 participants (90.8%) had a score greater than 1.0, indicating most participants had some degree of vaccine hesitancy. The final multivariate linear regression showed that greater vaccine hesitancy was associated with being Black (b = 0.149, p = 0.005), single (b = 0.070, p = 0.018), politically conservative (b = 0.157, p = 0.010), "anti-vaxxer" (b = 1.791, p < 0.001), concern about side effects (b = 0.226, p < 0.001), concern about safety (b = 0.260, p < 0.001), and being worried that the vaccine will not be effective (b = 0.169, p = 0.008) and they were being experimented on (b = 0.287, p < 0.001). Participants who were male White (b = -0.093, p = 0.008) and university graduates (b = -0.093, p < 0.001) and had a CD4 count of 200 cells/mm3 (b = -0.082, p = 0.048) and a liberal political orientation (b = -0.131, p < 0.001) were associated with lower vaccine hesitancy. CONCLUSIONS: Our findings provide important insights regarding COVID-19 vaccine hesitancy among PWH. Further efforts are required to understand how various social, political, and psychological factors contribute to COVID-19 vaccine hesitancy among key populations.

Preliminary Acceptability of a Home-Based Peripheral Blood Collection Device for Viral Load Testing in the Context of Analytical Treatment Interruptions in HIV Cure Trials: Results from a Nationwide Survey in the United States.

Frequent viral load testing is necessary during analytical treatment interruptions (ATIs) in HIV cure-directed clinical trials, though such may be burdensome and inconvenient to trial participants. We implemented a national, cross-sectional survey in the United States to examine the acceptability of a novel home-based peripheral blood collection device for HIV viral load testing. Between June and August 2021, we distributed an online survey to people with HIV (PWH) and community members, biomedical HIV cure researchers and HIV care providers. We performed descriptive analyses to summarize the results. We received 73 survey responses, with 51 from community members, 12 from biomedical HIV cure researchers and 10 from HIV care providers. Of those, 51 (70%) were cisgender men and 50 (68%) reported living with HIV. Most (>80% overall) indicated that the device would be helpful during ATI trials and they would feel comfortable using it themselves or recommending it to their patients/participants. Of the 50 PWH, 42 (84%) indicated they would use the device if they were participating in an ATI trial and 27 (54%) also expressed a willingness to use the device outside of HIV cure studies. Increasing sensitivity of viral load tests and pluri-potency of the device (CD4 count, chemistries) would augment acceptability. Survey findings provide evidence that viral load home testing would be an important adjunct to ongoing HIV cure-directed trials involving ATIs. Survey findings may help inform successful implementation and uptake of the device in the context of personalized HIV care.

Changes in Mental Health Among People with HIV During the COVID-19 Pandemic: Qualitative and Quantitative Perspectives.

People with HIV (PWH) are at risk for adverse mental health outcomes, which could be elevated during the COVID-19 pandemic. This study describes reasons for changes in mental health among PWH during the pandemic. Data come from closed- and open-ended questions about mental health changes from a follow-up to a cohort study on PWH in Florida during part of the COVID-19 pandemic (May 2020-March 2021). Qualitative data were analyzed using thematic analysis. Among the total sample of 227 PWH (mean age 50.0, 49.7% men, 69.2% Black/African American, 14.1% Hispanic/Latino), 30.4% reported worsened mental health, 8.4% reported improved mental health, and 61.2% reported no change. The primary reasons for worsened mental health were concerns about COVID-19, social isolation, and anxiety/stress; reasons for improved mental health included increased focus on individual wellness. Nearly one-third of the sample experienced worsened mental health. These results provide support for increased mental health assessments in HIV treatment settings.

Financial, Food, and Housing Insecurity Due to Coronavirus Disease 2019 Among At-Risk People With Human Immunodeficiency Virus in a Nonurban Ryan White HIV/AIDS Program Clinic.

Coronavirus disease 2019 negatively impacts social determinants of health that contribute to disparities for people with human immunodeficiency virus (HIV). Insecurity of food, housing, and employment increased significantly in April 2020 among patients with lower incomes at a Ryan White HIV/AIDS program clinic in the Southern United States.
