Systematic Review and Meta-Analyses of The Interaction Between HIV Infection And COVID-19: Two Years' Evidence Summary

Estimating risk of acquiring SARS-COV2 infection in treatment-experienced PLWH: A case-control study

Background

Risk factors for acquiring SARS-CoV-2 infection in people living with HIV (PLWH) and the true relationship between HIV and SARS CoV-2, are still not fully understood.

Objectives

The aim of this study was to identify the independent risk factors for SARS-CoV-2 acquisition in treatment experienced PLWH, shedding light on potential risk factors associated with SARS CoV-2 infection in PLWH undergoing treatment.

Study design

PLWH were recruited from the Infectious Diseases Outpatient Clinic of Fondazione Policlinico Universitario A.Gemelli IRCCS in Italy and randomly interviewed via a questionnaire during their follow-up visits to determine if they had experienced a SARS-CoV-2 infection between March 2020 and June 2022.For each participant with reported history of SARS-CoV-2 (cases), two PLWH with no declared COVID-19 infection were selected (controls); PLWH had a similar potential exposure time to SARS-CoV-2. A total 220 PLWH were selected: 72 cases and 148 controls. None developed severe Covid-19 disease and only one participant required hospitalization.

Results

Overall, 220 PLWH were enrolled: 72 cases and 148 controls. Characteristics of cases and controls were similar, except for the ART regimen used and the last HIV-RNA concentration before the enrollment date. By an adjusted multivariable logistic regression, the estimated odds of SARS-CoV-2 infection was higher in more recent years (2022 versus 2020 aOR 20.74, 95 % CI 5.26-81.8) and in PLWH with last HIV-RNA >50 cp/mL before enrollment date (versus <50 aOR 4.56, 95 % CI 1.01-20.46). A reduced odds was correlated with >3 vaccine doses (versus <3 or not vaccinated aOR 0.08, 95 % CI 0.02-0.24).

Conclusion

In this cohort, the odds of SARS-CoV-2 acquisition increased over time, probably due to change in lock-down measures and in SARS-CoV-2 circulating variants.Detectable viral load was associated with increased risk of infection, highlighting the importance of HIV-RNA monitoring during pandemics.

Coronavirus replicase epitopes induce cross-reactive CD8 T cell responses in SARS-CoV-2-naive people with HIV-1

Cross-reactive T cell immunity between common cold coronaviruses and SARS-CoV-2 may influence COVID-19 susceptibility. To identify cross-reactive CD8 T cell epitopes, we analyzed responses to 21 homologous SARS-CoV-2 replicase peptides in 177 people living with HIV (PLWH) on antiretroviral therapy, of which 133 did not have prior SARS-CoV-2 infection. Replicase peptides induced IFN-γ responses in 63% of the SARS-CoV-2-naïve individuals and in 73% of individuals with prior SARS-CoV-2-infection. We could define several cross-reactive epitopes, including the HLA-B∗35:03 restricted CoV-YL8, and characterized a CoV-YL8-specific T cell receptor cloned from a SARS-CoV-2 seronegative individual. Analysis of the association between HLA-I alleles and SARS-CoV-2 infections over a 16-months period revealed that in a cohort of 452 PLWH, HLA-B∗35:03 and C∗07 were underrepresented in the 55 persons with a history of SARS-CoV-2 infection while HLA-B∗35:01 and HLA-C∗04 were associated with a higher infection rate. Taken together, our study suggests an HLA-I-mediated effect of common cold coronaviruses on SARS-CoV-2 immunity.

Metabolomic Profiling Reveals Potential Biomarkers and Prominent Features in HIV/AIDS Patients Co-Infected with SARS-CoV-2

The underlying mechanisms and diagnostic biomarkers for the progress of COVID-19 in HIV patients have not been fully elucidated. In this study, the aim is to analyze the metabolomic profiles of HIV/AIDS patients co-infected with SARS-CoV-2 and to identify biomarkers indicative of co-infection. In this study, we conducted a retrospective cohort analysis of peripheral blood samples collected from 30 HIV/AIDS patients co-infected with SARS-CoV-2 (pc group) and 30 patients without SARS-CoV-2 (nc group). In this study, through non-targeted metabolomics and lipidomics analysis, 77 differential metabolites were identified in the plasma of patients co-infected with HIV and SARS-CoV-2 compared to the nc group, with vitamin K1 emerging as a significant feature. Moreover, the plasma of the pc group showed disturbances in lipid metabolism, with elevated triglycerides (TG) and phosphatidylcholine (PC) and decreased phosphatidylglycerol (PG) compared to the control group. Vitamin K1 may be a biomarker for SARS-CoV-2 in HIV/AIDS patients, and changes in the levels of TG, PC, and PG molecules appear to be the main features following HIV co-infection with COVID-19. The emphasis in our study is on the power of using comprehensive metabolomics (lipidomics) approaches to identify metabolic biomarkers and potential mechanisms of COVID-19 in HIV/AIDS patients.

Correlates of mental health of people living with HIV co-infected with SARS-CoV-2: findings from the COVIDHIV study in France

Background

The COVID-19 pandemic has severely affected vulnerable populations, especially individuals living with HIV/AIDS (PLWHA). The convergence of HIV/AIDS and COVID-19 presents unique challenges, exacerbating existing health concerns and magnifying the strain on individuals already grappling with compromised immune systems. This study aimed to investigate the mental well-being repercussions faced by PLWHA co-infected with SARS-CoV-2 in France.

Methods

COVIDHIV is a French multicenter cohort of PLWHA co-infected with SARS-CoV-2, which collected sociodemographic, clinical, and mental health data. Anxiety and depression symptoms and post-traumatic stress disorder (PTSD) were assessed by the Hospital Anxiety and Depression Scale (HADS) and the PTSD Checklist (PCL-S), respectively. Multivariable logistic regression was performed to identify factors associated with mental health outcomes at inclusion in the cohort.

Results

Of the 397 participants included, 64.7% were male. The mean age was 51.6 (± 11.8) years. The prevalence of mental health outcomes was 33.5% ([95%CI: 28.5-39.0%]) for anxiety, 21.0% ([16.8-25.9%]) for depression, and 12.2% ([8.9-16.5%]) for PTSD. In multivariable regression adjusted for sex, COVID-19 wave and duration between COVID-19 confirmation and enrolment, age (adjusted odds-ratio (aOR): 0.97 [0.95-0.99]), being professionally active (0.43 [0.25-0.75]), and the number of self-reported symptoms (1.17 [1.11-1.24]) were associated with anxiety. Being professionally active (0.34 [0.18-0.65]), living in a couple (0.52 [0.20-0.98]), number of self-reported symptoms (1.15 [1.08-1.22]), and hospitalization for COVID-19 (3.35 [1.34-8.33]) were associated with depression. The number of self-reported symptoms (1.27 [1.16-1.41]), psychiatric disorders (4.04 [1.48-11.11]), and perceived vulnerability to COVID-19 (4.53 [1.69-14.60]) were associated with PTSD.

Conclusion

The mental health is a challenging issue among the participants and needs to be closely monitored among people already affected by a chronic disease such as HIV. The findings underscore the urgent need for targeted support and interventions tailored to address the mental health needs of PLWHA facing the dual burden of HIV/AIDS and COVID-19.

Effect of HIV Status and Charlson Comorbidity Index on COVID-19 Clinical Outcomes in a Case-Control Study

OBJECTIVES

During the course of the coronavirus disease 2019 (COVID-19) pandemic, numerous comorbidities were identified as risk factors for increased morbidity and mortality. Few studies have examined human immunodeficiency virus (HIV) and COVID-19 co-infection and the impact of HIV on COVID-19 outcomes. In this study, we compared outcomes of people living with HIV with COVID-19 with a control group to examine outcomes.

METHODS

We identified 45 people living with HIV admitted with COVID-19 to one of three large healthcare systems in Memphis, Tennessee, between March 1 and October 31, 2020. We matched the people living with HIV in a 1:1 fashion to a control group of COVID-19-positive patients without a recorded history of HIV and compared clinical outcomes. Nine pairs were not able to be optimally matched, so a sensitivity analysis was completed by repeating the same analyses in the primary analysis while excluding the nine mismatched pairs.

RESULTS

Patients did not differ significantly in demographic variables due to the matching algorithm, and there was no significant difference in measured outcomes between people living with HIV and controls. A CD4 count of <200 cells per microliter was not significantly associated with increased morbidity or mortality. Controlling for HIV status, an elevated Charlson Comorbidity Index score of >3 was associated with increased intubation (P = 0.02), vasopressor use (odds ratio [OR] 4.81, P = 0.04), intensive care unit level of care (OR 4.37, P = 0.007), mortality (OR 7.14, P = 0.02), and length of overall hospital stay in days (P = 0.004).

CONCLUSIONS

We found no difference in outcomes of people living with HIV in comparison to matched controls based on HIV status but found that an increased Charlson Comorbidity Index score led to increased morbidity and mortality regardless of HIV status.

Effects of Pitavastatin on COVID-19 Incidence and Seriousness Among a Global Cohort of People With HIV

Background

Among people with HIV (PWH), COVID-19 is common and potentially severe. We leveraged REPRIEVE (Randomized Trial to Prevent Vascular Events in HIV) to assess the effects of statin therapy for cardiovascular disease prevention on COVID-19 outcomes (incidence and serious cases) among a global cohort of PWH.

Methods

COVID-19 data collection was implemented April 2020 to capture events from January 2020. COVID-19 was defined by positive test result or clinical diagnosis and serious COVID-19 according to the International Conference on Harmonisation definition. Among participants in follow-up on 1 January 2020, Cox proportional hazards modeling was used to estimate the hazard ratio (HR) of COVID-19 (pitavastatin/placebo), stratified by Global Burden of Disease region. Modification of statin effect following COVID-19 vaccination was evaluated via interaction with time-updated vaccination status.

Results

Among 6905 PWH, 32% were natal female and 41% were Black or African American. The median age was 53 years and the 10-year atherosclerotic cardiovascular disease risk score 4.5%. Statin therapy did not reduce COVID-19 incidence (HR, 1.05; 95% CI, .95-1.15) but appeared to reduce incidence of serious COVID-19 (HR, 0.75; 95% CI, .52-1.09). Among 1701 PWH with COVID-19, the relative risk (pitavastatin/placebo) for serious COVID-19 was 0.73 (95% CI, .52-1.03). The treatment effect size for serious COVID-19 fell within the hypothesized range, but the 95% CI crossed 1 given fewer-than-anticipated cases (117 vs 200). Furthermore, 83% reported COVID-19 vaccination by end of study, with a strong protective effect on serious COVID-19 (HR, 0.27; 95% CI, .14-.53; P < .0001). A protective statin effect was observed prior to vaccination.

Conclusions

Among PWH, statin therapy had no effect on COVID-19 incidence but showed potential to reduce risk of serious COVID-19 prior to COVID-19 vaccination.

When Pandemics Collide: Actionable Lessons in HIV Prevention, Treatment and Care During the Era of COVID-19

The articles in this special issue of AIDS and Behavior focus on the collision between HIV/AIDS and COVID-19 as intersecting pandemics that profoundly impacted communities globally. This editorial highlights the complex interplay between these two public health crises. The pandemic disrupted access to HIV prevention, testing, and treatment services, potentially jeopardizing decades of progress. Mental health challenges and social vulnerability among people living with HIV (PWH) were exacerbated, with preexisting health disparities amplified, disproportionately affecting marginalized populations. However, despite these challenges, the pandemic also spurred innovation and adaptation in HIV prevention and care, with increased use of telehealth and other modalities. The enduring and actionable lessons learned from the collision of HIV and COVID-19 pandemics can prepare us for the next public health challenge with two calls for action. First, we call for integrated and equitable responses that address the multifaceted challenges faced by individuals and communities affected by HIV in the post-COVID-19 era. Second, we call for a strengthened commitment to building resilient health systems and community-engaged interventions that can withstand future challenges.

People living with HIV with the Omicron variant infection have milder COVID-19 symptoms: results from a cross-sectional study

BACKGROUND

China braces for coronavirus disease 2019 (COVID-19) surge after adjusting the "zero COVID" strategy. We aimed to evaluate and compare the prevalence of clinical symptoms of the Omicron variant infection among people living with HIV (PLWH) and HIV-free people.

METHODS

A cross-sectional study was conducted in Wuchang District, Wuhan, Hubei Province, in December 2022 by a self-administered online survey during the Omicron wave. Participants aged ≥ 18 years with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diagnosis were recruited. PLWH managed by the local healthcare system were recruited, while HIV-free people were recruited by sending out online surveys through WeChat. We compared the prevalence of clinical symptoms of COVID-19 between PLWH and HIV-free people, and factors associated with symptom occurrence among PLWH were accessed.

RESULTS

Total, 687 PLWH and 1222 HIV-free people were enrolled. After adjusting sex, age, body mass index, comorbidities and COVID-19 vaccination status, the prevalences of all symptoms, including higher degree and long duration of fever (aOR 0.51, 95%CI 0·42 - 0·61; aOR 0.52, 95%CI 0·43 - 0·63), were significantly lower among PLWH than among HIV-free people. Among PLWH, CD4+ T lymphocyte count (CD4 count) between 350 ~ 499 cells/µL and detectable HIV viral load (HIV-VL) were associated with significantly decreased risks of fever (aOR 0·63, 95%CI 0·40 - 0·97; aOR 0·56, 95%CI 0·33 - 0·94), headache (aOR 0·61, 95%CI 0·41 - 0·91; aOR 0·55, 95%CI 0·34 - 0·92) and muscle soreness (aOR 0·57, 95%CI 0·39 - 0·84; aOR 0·57, 95%CI 0·39 - 0·84). No apparent association between the symptoms prevalence and three/four doses of inactivated COVID-19 vaccination among PLWH was observed; both males and older age were associated with significantly decreased risks of nasal congestion/runny nose (aOR 0·52, 95%CI 0·32 - 0·82; aOR 0·97, 95%CI 0·96 - 0·99) and headache (aOR 0·58, 95%CI 0·36 - 0·92; aOR 0·96, 95%CI 0·95 - 0·98); older age was associated with significantly decreased risks of higher degree of fever (aOR 0·97, 95%CI 0·95 - 0·98).

CONCLUSIONS

PLWH have significantly milder symptoms of the Omicron variant infection than HIV-free people. PLWH who are male, older, have low CD4 count, and detectable HIV-VL have reduced occurrence of COVID-19 symptoms. However, continuous monitoring should be conducted among PLWH during the COVID-19 pandemic.

SARS-CoV-2 Variants and Clinical Outcomes of Special Populations: A Scoping Review of the Literature

The ongoing COVID-19 pandemic has significantly impacted special populations, including immunocompromised individuals, people living with HIV (PLWHIV), pediatric patients, and those with chronic liver disease (CLD). This scoping review aims to map the clinical outcomes of these vulnerable groups when infected with various SARS-CoV-2 variants. The review identifies trends and patterns, noting that early variants, such as Alpha and Delta, are associated with more severe outcomes, including higher hospitalization and mortality rates. In contrast, the Omicron variant, despite its increased transmissibility, tends to cause milder clinical manifestations. The review highlights the necessity for ongoing surveillance and tailored healthcare interventions due to the heterogeneity of patient populations and the evolving nature of the virus. Continuous monitoring and adaptive healthcare strategies are essential to mitigate the impact of COVID-19 on these high-risk groups.

Immunogenicity of a bivalent BA.1 COVID-19 booster vaccine in people with HIV in the Netherlands

OBJECTIVE

We evaluated the immunogenicity of a bivalent BA.1 COVID-19 booster vaccine in people with HIV (PWH).

DESIGN

Prospective observational cohort study.

METHODS

PWH aged ≥45 years received Wuhan-BA.1 mRNA-1273.214 and those <45 years Wuhan-BA.1 BNT162b2. Participants were propensity score-matched 1 : 2 to people without HIV (non-PWH) by age, primary vaccine platform (mRNA-based or vector-based), number of prior COVID-19 boosters and SARS-CoV-2 infections, and spike (S1)-specific antibodies on the day of booster administration. The primary endpoint was the geometric mean ratio (GMR) of ancestral S1-specific antibodies from day 0 to 28 in PWH compared to non-PWH. Secondary endpoints included humoral responses, T-cell responses and cytokine responses up to 180 days post-vaccination.

RESULTS

Forty PWH received mRNA-1273.214 ( N  = 35) or BNT162b2 ( N  = 5) following mRNA-based ( N  = 29) or vector-based ( N  = 11) primary vaccination. PWH were predominantly male (87% vs. 26% of non-PWH) and median 57 years [interquartile range (IQR) 53-59]. Their median CD4 + T-cell count was 775 (IQR 511-965) and the plasma HIV-RNA load was <50 copies/ml in 39/40. The GMR of S1-specific antibodies by 28 days post-vaccination was comparable between PWH [4.48, 95% confidence interval (CI) 3.24-6.19] and non-PWH (4.07, 95% CI 3.42-4.83). S1-specific antibody responses were comparable between PWH and non-PWH up to 180 days, and T-cell responses up to 90 days post-vaccination. Interferon-γ, interleukin (IL)-2, and IL-4 cytokine concentrations increased 28 days post-vaccination in PWH.

CONCLUSION

A bivalent BA.1 booster vaccine was immunogenic in well treated PWH, eliciting comparable humoral responses to non-PWH. However, T-cell responses waned faster after 90 days in PWH compared to non-PWH.

SARS-CoV-2 seroprevalence and associated factors among people living with HIV in Sierra Leone

BACKGROUND

Human immunodeficiency virus (HIV) infection is an important risk factor for Coronavirus Disease 2019 (COVID-19), but data on the prevalence of COVID-19 among people living with HIV (PLWH) is limited in low-income countries. Our aim was to assess the seroprevalence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) specific antibodies and associated factors among PLWH in Sierra Leone.

METHODS

We conducted a cross-sectional survey of PLWH aged 18 years or older in Sierra Leone between August 2022 and January 2023. Participants were tested for SARS-CoV-2 antibodies using a rapid SARS-CoV-2 antibody (immunoglobulin M/immunoglobulin G [IgG]) kits. Stepwise logistic regression was used to explore factors associated with SARS-CoV-2 antibody seroprevalence with a significance level of p < .05.

RESULTS

In our study, 33.4% (1031/3085) participants had received a COVID-19 vaccine, and 75.7% were SARS-CoV-2 IgG positive. Higher IgG seroprevalence was observed in females (77.2% vs. 71.4%, p = .001), adults over 60 years (88.2%), those with suppressed HIV RNA (80.7% vs. 51.7%, p < .001), antiretroviral therapy (ART)-experienced individuals (77.9% vs. 44.6%, p < .001), and vaccinated participants (80.7% vs. 73.2%, p < .001). Patients 60 years or older had the highest odds of IgG seroprevalence (adjusted odds ratio [aOR] = 2.73, 95% CI = 1.68-4.65). Female sex (aOR = 1.28, 95%CI = 1.05-1.56), COVID-19 vaccination (aOR = 1.54, 95% CI = 1.27-1.86), and ART (aOR = 2.20, 95% CI = 1.56-3.11) increased the odds, whereas HIV RNA ≥ 1000 copies/mL (aOR = 0.32, 95% CI = 0.26-0.40) reduced the odds of IgG seroprevalence.

CONCLUSIONS

We observed a high seroprevalence of SARS-CoV-2 antibody among PLWH in Sierra Leone. We recommend the introduction of targeted vaccination for PLWH with a high risk of severe COVID-19, especially those with an unsuppressed HIV viral load.

Similar Limited Protection Against Severe Acute Respiratory Syndrome Coronavirus 2 Omicron Infection in Vaccinated Individuals With HIV and Comparable Controls

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.

COVID-19 Vaccine Hesitancy Among People Living with HIV: A Systematic Review and Meta-Analysis

Vaccine hesitancy is one of the top 10 threats to global health, which affects the prevalence and fatality of vaccine-preventable diseases over the world. During the COVID-19 pandemic, people living with HIV (PLWH) may have higher risks of infection, more serious complications, and worse prognosis without the protection of the COVID-19 vaccine. A systematic review and meta-analysis aiming to evaluate the prevalence of COVID-19 vaccine hesitancy among PLWH was conducted using PubMed, Embase, and Web of Science databases for studies published between January 1, 2020, and August 31, 2022. The pooled prevalence with a corresponding 95%CI of COVID-19 vaccine hesitancy among PLWH was reported. Subgroup analysis was conducted to explore variation in prevalence across different categories. 23 studies with a total of 19,922 PLWH were included in this study. The prevalence of COVID-19 vaccine hesitancy among PLWH was 34.0%, and the influencing factors included male, influenza vaccination experience, and a CD4 count of more than 200 cells/mm3. Subgroup analysis did not identify significant causes of heterogeneity but showed that the prevalence of COVID-19 vaccine hesitancy among PLWH varies by study period, region, and race. Although all PLWH are recommended to receive the COVID-19 vaccine, a large proportion of them remain hesitant to be vaccinated. Therefore, governments and relevant institutions should take specific measures to encourage and promote vaccination to improve the coverage of the COVID-19 vaccine among PLWH.

The impact of immunosuppression on the mortality and hospitalization of Monkeypox: a systematic review and meta-analysis of the 2022 outbreak

BACKGROUND

Limited data is available regarding the severity and mortality of Mpox in individuals with immunocompromised conditions. Therefore, we performed this meta-analysis to understand the impact of HIV- or non-HIV-associated immunosuppression on the severity of Mpox requiring hospitalization and mortality.

METHODS

A thorough literature search was performed from 2022 up to January 2024. The results were presented as odds ratios (ORs). We only included patients who required hospitalization for severity rather than isolation.

RESULTS

A total of 34 studies were included in this analysis. Our analysis did not find a significant difference in the hospitalization risk between HIV-positive individuals and those who were HIV-negative (OR = 1.03; P = 0.85; 7 studies; CD4 count of fewer than 200 cells/µL was less than 0.5% across all studies). Patients with a CD4 count lower than 200 cells/µL or an unsuppressed RNA viral load (> 200 copies/ml) had a significantly higher hospitalization risk (OR = 5.3, P < 0.001) and (OR = 3, P < 0.001), respectively. Most of the reported deaths were reported in patients with HIV with CD4 counts below 200 cells/µL, with some fatal cases occurring in non-HIV immunosuppressed patients, particularly organ transplant recipients. Based on the autopsy findings, Mpox was confirmed in multiple organs, particularly the digestive tract, lung, and testes. Furthermore, some studies documented cases of death that were suspected to be related to hemophagocytic lymphohistiocytosis (HLH) and immune reconstitution inflammatory syndrome (IRIS). Most of the death reports showed concomitant non-Mpox infections at the time of hospitalization and death CONCLUSIONS: Our finding shows that Mpox acts as an opportunistic pathogen in immunocompromised individuals. These individuals should be prioritized for early care and closely monitored for signs of deteriorating clinical conditions. Clinical manifestations and autopsy findings strongly suggest Mpox dissemination to multiple organs, particularly the digestive tract, and lungs. However, the presence of concomitant non-Mpox infections complicates the assessment of the attribution of Mpox to death. Caution should be exercised when interpreting data suggesting poorer outcomes in individuals with non-HIV immunosuppression, as current evidence is scarce and further research is needed.

Clinical Outcomes of Coronavirus Disease 2019 in People Living With Human Immunodeficiency Virus in South Korea: A Nationwide Population-Based Cohort Study

BACKGROUND

We aimed to compare the epidemiological and clinical characteristics of coronavirus disease 2019 (COVID-19) in people living with human immunodeficiency virus (HIV) (PLWH) with those in people living without HIV (PLWoH).

METHODS

This nationwide descriptive epidemiological study was conducted in South Korea between January 2020 and February 2022. The National Health Insurance claim data, comprising the data of the entire Korean population, were collected through the Health Insurance Review and Assessment Service.

RESULTS

Among 3,653,808 individuals who were diagnosed with COVID-19, 1311 (0.04%) were PLWH. All PLWH received antiretroviral therapy, and 26.47% had more than one underlying disease other than HIV infection. The overall in-hospital mortality rates of PLWH and PLWoH were 0.76% and 0.25%, respectively (P = 0.002). According to the Cox proportional hazard model, no significant difference was observed in the in-hospital mortality rate (hazard ratio [HR]: 1.80, 95% confidence interval [CI]: 0.70-4.67) between the PLWH and PLWoH. However, progression to severe or critical COVID-19 was more common in PLWH (HR: 2.70, 95% CI: 1.37-5.33). In PLWH diagnosed with COVID-19, a multivariable Cox regression analysis found old age (≥ 60 years) (HR: 6.9, 95% CI: 2.57-18.56) and diabetes mellitus (HR: 5.13, 95% CI: 2.02-13.00) as the independent risk factors for severe or critical COVID-19.

CONCLUSIONS

PLWH had a significantly higher risk of developing severe or critical COVID-19 compared with PLWoH. Our findings suggest the need for implementing tailored strategies to decrease the impact of COVID-19 on PLWH.

COVID-19 Severity in People With HIV Compared With Those Without HIV

BACKGROUND

People with HIV (PWH) may be at risk for more severe COVID-19 outcomes. We compared risk for severe COVID-19 in PWH with matched individuals without HIV.

METHODS

We identified adults in Massachusetts with a positive SARS-CoV-2 test, March 2020-July 2022, using electronic medical record data from 3 large clinical practice groups. We then used regression models to compare outcomes among PWH versus propensity score-matched people without HIV (matched 20:1) for severe COVID-19 (pneumonia or acute respiratory distress syndrome), hospitalization, and hospital length of stay.

RESULTS

We identified 171,058 individuals with COVID-19; among them, 768 PWH were matched to 15,360 individuals without HIV. Overall, severe COVID-19 and hospitalization were similar in PWH and those without HIV (severe COVID-19: 3.8% vs 3.0%, adjusted odds ratio [OR] 1.27, 95% confidence interval [CI]: 0.86-1.87; hospitalization: 12.1% vs 11.3%, adjusted OR: 1.08, 95% CI: 0.87 to 1.35). Compared with people without HIV, PWH with low CD4 T-cell counts (<200 cells/mm 3 ) had more severe COVID-19 (adjusted OR: 3.99, 95% CI: 2.06 to 7.74) and hospitalization (adjusted OR: 2.26, 95% CI: 1.35 to 3.80), but PWH with high CD4 counts had lower odds of hospitalization (adjusted OR: 0.73, 95% CI: 0.52 to 1.03).

CONCLUSIONS

PWH with low CD4 T-cell counts had worse COVID-19 outcomes compared with people without HIV, but outcomes for those with high CD4 counts were similar to, or better than, those without HIV. It is unclear whether these findings are generalizable to settings where PWH have less access to and engagement with health care.

Factors Associated With COVID-19 Vaccination Among Racial/Ethnic Minority Groups With HIV in South Florida

BACKGROUND

Racial/ethnic minority groups with HIV in the United States are particularly vulnerable to COVID-19 consequences and can significantly benefit from increased uptake of COVID-19 vaccines. This study identified factors associated with full COVID-19 vaccination among people with HIV.

SETTING

Ryan White HIV/AIDS Program in Miami-Dade County, FL.

METHODS

Data were collected from 299 Ryan White HIV/AIDS Program adult clients during January-March 2022 using a cross-sectional phone survey. Multivariable logistic regression was used to estimate adjusted odds ratios (aORs) with 95% confidence intervals (CIs). All analyses were weighted to be representative of the race/ethnicity and sex distribution of clients in the Ryan White HIV/AIDS Program.

RESULTS

Eighty-four percent of participants were fully vaccinated with a primary vaccine series; stratified by race/ethnicity, the percentages were 88.9% of Hispanic, 72.0% of black/African American, and 67.5% of Haitian participants. Fully vaccinated participants were less likely to be black/African American than Hispanic (aOR = 0.18; 95% CI: 0.05 to 0.67) and more likely to not endorse any misconceptions about COVID-19 vaccines (aOR = 8.26; 95% CI: 1.38 to 49.64), to report encouragement to get vaccinated from sources of information (aOR = 20.82; 95% CI: 5.84 to 74.14), and to perceive that more than 50% of their social network was vaccinated (aOR = 3.35; 95% CI: 1.04 to 10.71). Experiences of health care discrimination, structural barriers to access vaccines, and recommendations from HIV providers were not associated with full vaccination.

CONCLUSIONS

These findings highlight the importance of delivering accurate and positive messages about vaccines and engaging social networks to promote COVID-19 vaccination among people with HIV. This information can be leveraged to promote uptake of subsequent boosters and other recommended vaccines.

The immune response to SARS-CoV-2 in people with HIV

This review examines the intersection of the HIV and SARS-CoV-2 pandemics. People with HIV (PWH) are a heterogeneous group that differ in their degree of immune suppression, immune reconstitution, and viral control. While COVID-19 in those with well-controlled HIV infection poses no greater risk than that for HIV-uninfected individuals, people with advanced HIV disease are more vulnerable to poor COVID-19 outcomes. COVID-19 vaccines are effective and well tolerated in the majority of PWH, though reduced vaccine efficacy, breakthrough infections and faster waning of vaccine effectiveness have been demonstrated in PWH. This is likely a result of suboptimal humoral and cellular immune responses after vaccination. People with advanced HIV may also experience prolonged infection that may give rise to new epidemiologically significant variants, but initiation or resumption of antiretroviral therapy (ART) can effectively clear persistent infection. COVID-19 vaccine guidelines reflect these increased risks and recommend prioritization for vaccination and additional booster doses for PWH who are moderately to severely immunocompromised. We recommend continued research and monitoring of PWH with SARS-CoV-2 infection, especially in areas with a high HIV burden.

A systematic review and meta-analysis of the global prevalence and determinants of COVID-19 vaccine acceptance and uptake in people living with HIV

People living with HIV (PLHIV) are at higher risk of poor outcomes of SARS-CoV-2 infection. Here we report the pooled prevalence of COVID-19 vaccine acceptance/uptake and determinants among this vulnerable population of PLHIV based on a systematic review and meta-analysis of studies published by 25 August 2023. Among the 54 included studies (N = 167,485 participants), 53 (N = 166,455) provided data on vaccine acceptance rate, while 27 (N = 150,926) provided uptake data. The global prevalences of COVID-19 vaccine acceptance and uptake were 67.0% and 56.6%, respectively. Acceptance and uptake rates were 86.6% and 90.1% for the European Region, 74.9% and 71.6% for the Region of the Americas, 62.3% and 78.9% for the South-East Asian Region, 64.6% and 19.3% for the Eastern Mediterranean Region, 58.0% and 35.5% for the African Region, and 57.4% and 44.0% for the Western Pacific Region. The acceptance rate increased from 65.9% in 2020 to 71.0% in 2022, and the uptake rate increased from 55.9% in 2021 to 58.1% in 2022. Men, PLHIV aged ≥40 years and those who had recently received the influenza vaccine were more likely to accept and receive the COVID-19 vaccine. Factors associated with lower uptake included Black race, other races (Latinx/Hispanic/mixed race), low education level and being unemployed. Vaccine-related factors associated with higher acceptance included belief in vaccine effectiveness, vaccine trust, perceived high susceptibility to SARS-CoV-2 infection and fear of potential COVID-19 effect in PLHIV. Sustained efforts and targeted interventions are needed to reduce regional disparities in COVID-19 vaccine uptake among PLHIV.

Are people living with HIV have a low vulnerability to omicron variant infection: results from a cross-sectional study in China

BACKGROUND

A surge of more than 80 million Omicron variant infected cases was reported in China less than a month after the "zero COVID" strategy ended on December 7, 2022. In this circumstance, whether people living with HIV (PLWH) in China experience a similar risk is not clear.

METHODS

A cross-sectional study was conducted in the Wuchang District of Wuhan between December 20, 2022, and January 18, 2023 through a self-administered online survey. PLWH and HIV-negative people aged ≥ 18 years old who volunteered for this survey were eligible. The prevalence of Omicron variant infection between PLWH and HIV-negative people was compared, and the factors associated with the Omicron variant infection among PLWH and HIV-negative people were further evaluated, respectively.

RESULTS

In total, 890 PLWH and 1,364 HIV-negative adults from Wuchang District were enrolled. Among these participants, 690 PLWH (77.5%) and 1163 HIV-negative people (85.3%) reported SARS-CoV-2 infection. Gender, chronic disease conditions, and COVID-19 vaccination status significantly differed between the two groups. After adjusting gender, age, comorbidities, and COVID-19 vaccination status, the risk of SARS-CoV-2 infection among PLWH was significantly lower than among HIV-negative people (aOR 0.56, 95%CI 0.42-0.76). Multivariable logistic regression analysis showed that PLWH with older age and detectable HIV-viral load (HIV-VL) had decreased risk of SARS-CoV-2 infection (aOR 0.98, 95%CI 0.96-0.99; aOR 0.59, 95%CI 0.36-0.97). Compared with PLWH receiving one/two doses of COVID-19 vaccines, no significant differences in the risk of SARS-CoV-2 infection were observed among PLWH receiving three doses of inactivated vaccines and four doses of vaccines (three doses of inactivated vaccines plus one dose of inhaled recombinant adenovirus type 5 (AD5)-vectored vaccine). Among HIV-negative people, those receiving four doses of COVID-19 vaccines had a lower risk of SARS-CoV-2 infection than those receiving one/two doses (aOR 0.14, 95%CI 0.08-0.25).

CONCLUSIONS

Our study proves that PLWH have a lower risk of Omicron variant infection than HIV-negative people. However, even PLWH with younger age and virological suppression should strengthen the prevention against SARS-CoV-2 infection. Three doses of inactivated vaccines plus one dose of inhaled recombinant AD5-vectored COVID-19 vaccine may provide better protection for HIV-negative people.

COVID-19 infection in people living with HIV

BACKGROUND

Coronavirus disease 2019 (COVID-19) and human immunodeficiency virus (HIV) are intersecting pandemics, with implications for care at an individual and global scale.

SOURCES OF DATA

PubMed search with relevant articles and their references reviewed.

AREAS OF AGREEMENT

COVID-19 has changed the delivery of care to people living with HIV (PLWH). Vaccines are efficacious and safe for PLWH; patient care for symptomatic COVID-19 is similar to that of people without HIV.

AREAS OF CONTROVERSY

It remains unclear whether PLWH experience increased COVID-19-specific mortality. Treatments to reduce severity in early COVID-19 infection lack evidence in PLWH.

GROWING POINTS

The effects of the COVID-19 pandemic on HIV-related morbidity and mortality are yet to be seen. COVID-19 epidemiology among PLWH is complicated by changes to the severe acute respiratory syndrome coronavirus 2, population behaviours and vaccine availability.

AREAS TIMELY FOR DEVELOPING RESEARCH

Global trends in HIV-related morbidity and mortality should be monitored to appreciate the effects of the COVID-19 pandemic. The benefits of early antiviral and/or neutralizing monoclonal antibody (nMAb) treatment for PLWH and nMAb prophylaxis require investigation.

Safety and Immunogenicity of SARS-CoV-2 Vaccines in People Living With HIV (PLWH): A Systematic Review and Meta-analysis of Real-World Studies

The safety and immunogenicity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in people living with HIV (PLWH) in real world studies remain controversial. Thus, we conducted a comprehensive systematic review and meta-analysis to address this issue. Data search were conducted from PubMed, Web of science, and Embase. Adverse events following vaccination, the risk ratio (RR) of SARS-CoV-2-specific IgG seroconversion, and the level of anti-SARS-CoV-2 neutralizing antibodies were compared between the PLWH group and a healthy control group. A total of 10,582 PLWH from 22 studies were included. In our analysis, the incidence of local or systemic adverse events after the first SARS-CoV-2 vaccine dose was not statistically different between PLWH and healthy controls. However, there was a statistical difference after the second dose (RR = 0.83, 95% CI: 0.71 – 0.98). The seroconversion rate of SARS-CoV-2 IgG antibodies in PLWH was significantly lower than that in the healthy control group (RR = 0.94, 95% CI: 0.89-0.98; I2 = 80%, P < 0.01). The anti-SARS-CoV-2 neutralizing antibody titers in PLWH after full immunization were also significantly lower than that in the healthy control group (RR = 0.91, 95% CI: 0.85-0.98; I2 = 81%, P < 0.01). The safety and tolerance of COVID-19 vaccines in PLWH are acceptable. However, their immunogenicity may be impaired to a certain extent, characterized by a lower IgG seroconversion rate and neutralizing antibody titers compared with healthy individuals. These findings should provide guidance for optimizing future COVID-19 vaccination strategies among PLWH.

The Impact of COVID-19 on People Living with HIV-1 and HIV-1-Associated Neurological Complications

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is the causative pathogen of the coronavirus disease 2019 (COVID-19) pandemic, a fatal respiratory illness. The associated risk factors for COVID-19 are old age and medical comorbidities. In the current combined antiretroviral therapy (cART) era, a significant portion of people living with HIV-1 (PLWH) with controlled viremia is older and with comorbidities, making these people vulnerable to SARS-CoV-2 infection and COVID-19-associated severe outcomes. Additionally, SARS-CoV-2 is neurotropic and causes neurological complications, resulting in a health burden and an adverse impact on PLWH and exacerbating HIV-1-associated neurocognitive disorder (HAND). The impact of SARS-CoV-2 infection and COVID-19 severity on neuroinflammation, the development of HAND and preexisting HAND is poorly explored. In the present review, we compiled the current knowledge of differences and similarities between SARS-CoV-2 and HIV-1, the conditions of the SARS-CoV-2/COVID-19 and HIV-1/AIDS syndemic and their impact on the central nervous system (CNS). Risk factors of COVID-19 on PLWH and neurological manifestations, inflammatory mechanisms leading to the neurological syndrome, the development of HAND, and its influence on preexisting HAND are also discussed. Finally, we have reviewed the challenges of the present syndemic on the world population, with a particular emphasis on PLWH.

Non-alcoholic fatty liver disease (NAFLD) and COVID-19 outcomes: A systematic review, meta-analysis, and meta-regression

It is important to identify risk factors for poor outcomes of coronavirus disease 2019 (COVID-19) patients. Currently, the correlation between non-alcoholic fatty liver disease (NAFLD) and COVID-19 outcomes has not been established. This study was conducted to determine the association between NAFLD and in-hospital outcomes of COVID-19 patients. The systematic searches were conducted by using PubMed and the Europe PMC databases and particular keywords were used as of December 10, 2020. Further searches were conducted up to 2022. All articles that include data about COVID-19 and fatty liver disease were collected. Statistical analysis was performed by using Review Manager 5.4 and Comprehensive Meta-Analysis version 3 software. A total of 7,210 COVID-19 patients from 18 studies were included in the final analysis. Meta-analysis revealed that NAFLD increased the risk of developing poor in-hospital outcome (pooled both severe disease and death) in COVID-19 patients (RR 1.42; 95%CI: 1.17-1.73, p<0.001, I2=84%, random-effect modeling). Subgroup analysis however found that having NAFLD only increased the chance of getting severe COVID-19 (RR 1.67; 95%CI: 1.32-2.13, p<0.001, I2=86%, random-effect modeling) and not mortality (RR 1.00; 95%CI: 0.68-1.47, p=0.98, I2=80%, random-effect modeling). Meta-regression suggested that age (p=0.001) and diabetes (p=0.029) were significantly influenced the relationship between NAFLD and in-hospital outcomes of COVID-19 (pooled both severe disease and mortality). The weaker association of NAFLD and in-hospital outcomes of COVID-19 was found for studies with median age ≥45 years old (RR 1.29) when compared to studies with median age <45 years old (RR 2.96). In addition, studies with the prevalence of diabetes ≥25% (RR 1.29) had a weaker association with in-hospital outcomes when compared to studies with diabetes prevalence <25% (RR 1.85). In conclusion, NAFLD increased the risk of chance of getting severe COVID-19 and therefore it should be evaluated closely to reduce the chance of getting severe COVID-19.

HIV and COVID-19 Co-Infection: Epidemiology, Clinical Characteristics, and Treatment

The COVID-19 pandemic has been a global medical emergency with a significant socio-economic impact. People with HIV (PWH), due to the underlying immunosuppression and the particularities of HIV stigma, are considered a vulnerable population at high risk. In this review, we report what is currently known in the available literature with regards to the clinical implications of the overlap of the two epidemics. PWH share the same risk factors for severe COVID-19 as the general population (age, comorbidities), but virological and immunological status also plays an important role. Clinical presentation does not differ significantly, but there are some opportunistic infections that can mimic or co-exist with COVID-19. PWH should be prime candidates for preventative COVID-19 treatments when they are available, but in the setting of resistant strains, this might be not easy. When considering small-molecule medications, physicians need to always remember to address potential interactions with ART, and when considering immunosuppressants, they need to be aware of potential risks for opportunistic infections. COVID-19 shares similarities with HIV in how the public perceives patients-with fear of the unknown and prejudice. There are opportunities for HIV treatment hidden in COVID-19 research with the leaps gained in both monoclonal antibody and vaccine development.

Estimating the global impact of coronavirus disease 2019 on people living with HIV

PURPOSE OF REVIEW

The COVID-19 pandemic and public health response have directly and indirectly affected broader health outcomes, especially for those with existing chronic conditions, including HIV. We examine our current understanding of the global impact of COVID-19 on people with HIV (PWH).

RECENT FINDINGS

The interaction between COVID-19 and HIV is complex, making it challenging to estimate its true impact on PWH. Evidence to date does not suggest that HIV confers a higher risk of acquiring SARS-CoV-2. However, once acquired, HIV increases the risk of severe COVID-19 and mortality, particularly in immunosuppressed viraemic individuals and in the context of traditional COVID-19 risk factors, including disparities in social determinants of health. In addition, COVID-19 vaccines may be less effective in the context of HIV infection with additional doses needed. The consequences of disruption of access to essential prevention and treatment services because of the pandemic are becoming evident and will likely adversely affect outcomes, risking decades of progress.

SUMMARY

Given the increased mortality risk and reduced vaccine effectiveness seen in PWH, specific prevention and support measures are needed, including prioritization of vaccination and boosters, funding to mitigate the impact of pandemic and enabling integrated healthcare delivery during pandemics will be critical.

SARS-CoV-2 and HIV: Impact on Pulmonary Epithelial Cells

The SARS-CoV-2 pandemic provides a natural opportunity for the collision of coronavirus disease-2019 (COVID-19) with chronic infections, which place numerous individuals at high risk of severe COVID-19. Infection with Human Immunodeficiency Virus (HIV), a global epidemic, remains a major public health concern. Whether prior HIV+ status exacerbates COVID-19 warrants investigation. Herein, we characterized the impact of SARS-CoV-2 in human bronchial epithelial cells (HBECs) previously exposed to HIV. We optimized the air-liquid interface (ALI) cell culture technique to allow for challenges with HIV at the basolateral cell surface and SARS-CoV-2 spike protein on the apical surface, followed by genetic analyses for cellular stress/toxicity and innate/adaptive immune responses. Our results suggest that the IL-10 pathway was consistently activated in HBECs treated with spike, HIV, or a combination. Recombinant spike protein elicited COVID-19 cytokine storms while HIV activated different signaling pathways. HIV-treated HBECs could no longer activate NF-kB, pro-inflammatory TRAF-6 ubiquitination nor RIP1 signaling. Combinations of HIV and SARS-CoV-2 spike increased gene expression for activation of endoplasmic reticulum-phagosome pathway and downregulated non-canonical NF-kB pathways that are key in functional regulatory T cells and RNA Polymerase II transcription. Our in vitro studies suggest that prior HIV infection may not exacerbate COVID-19. Further in vivo studies are warranted to advance this field.
