Abstract
Exposure to heavy metals and lifestyle factors like smoking contribute to the production of free oxygen radicals. This fact, combined with a lowered total antioxidant status, can induce even more damage in the development of ankylosing spondylitis (AS). Despite the fact that some researchers are looking for more genetic factors underlying AS, most studies focus on polymorphisms within the genes encoding the human leukocyte antigen (HLA) system. The biggest challenge is finding the effective treatment of the disease. Genetic factors and the influence of oxidative stress, mineral metabolism disorders, microbiota, and tobacco smoking seem to be of great importance for the development of AS. The data contained in this review constitute valuable information and encourage the initiation and development of research in this area, showing connections between inflammatory disorders leading to the pathogenesis of AS and selected environmental and genetic factors.

Abstract
HIV-1 encodes four accesory proteins in addition to its structural and regulatory genes. Uniquely amongst them, Vpr is abundantly present within virions, meaning it is poised to exert various biological effects on the host cell upon delivery. In this way, Vpr contributes towards the establishment of a successful infection, as evidenced by the extent to which HIV-1 depends on this factor to achieve full pathogenicity in vivo. Although HIV infects various cell types in the host organism, CD4+ T cells are preferentially targeted since they are highly permissive towards productive infection, concomitantly bringing about the hallmark immune dysfunction that accompanies HIV-1 spread. The last several decades have seen unprecedented progress in unraveling the activities Vpr possesses in the host cell at the molecular scale, increasingly underscoring the importance of this viral component. Nevertheless, it remains controversial whether some of these advances bear in vivo relevance, since commonly employed cellular models significantly differ from primary T lymphocytes. One prominent example is the "established" ability of Vpr to induce G2 cell cycle arrest, with enigmatic physiological relevance in infected primary T lymphocytes. The objective of this review is to present these discoveries in their biological context to illustrate the mechanisms whereby Vpr supports HIV-1 infection in CD4+ T cells, whilst identifying findings that require validation in physiologically relevant models.

Abstract
OBJECTIVE There has been interest in a possible negative association between HIV and multiple sclerosis (MS). We aimed to compare the risk of MS in a cohort of individuals living with HIV to that in the general population. METHODS Population-based health data were accessed for 2 cohorts of HIV-positive persons from Sweden and British Columbia, Canada. Incident MS was identified using MS registries or a validated algorithm applied to administrative data. Individuals with HIV were followed from 1 year after the first clinical evidence of HIV or the first date of complete administrative health data (Canada = April 1, 1992 and Sweden = January 1, 2001) until the earliest of incident MS, emigration, death, or study end (Canada = March 31, 2020 and Sweden = December 31, 2018). The observed MS incidence rate in the HIV-positive cohort was compared to the expected age-, sex-, calendar year-, income-specific, and region of birth-specific rates in a randomly selected sample of >20% of each general population. The standardized incidence ratio (SIR) for MS following the first antiretroviral therapy exposure ("ART-exposed") was also calculated. RESULTS The combined Sweden-Canada cohort included 29,163 (75% men) HIV-positive persons. During 242,248 person-years of follow-up, 14 incident MS cases were observed in the HIV-positive cohort, whereas 26.19 cases were expected. The SIR for MS in the HIV-positive population was 0.53 (95% confidence interval [CI] = 0.32-0.90). The SIR for MS following the first ART exposure was 0.55 (95% CI = 0.31-0.96). INTERPRETATION This international population-based study demonstrated a lower risk of MS among HIV-positive individuals, and HIV-positive ART-exposed individuals. These findings provide support for further exploration into the relationship among HIV, ART, and MS. ANN NEUROL 2024;95:487-494.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic triggered an unprecedented concentration of economic and research efforts to generate knowledge at unequalled speed on deregulated interferon type I signalling and nuclear factor kappa light chain enhancer in B-cells (NF-κB)-driven interleukin (IL)-1β, IL-6, IL-18 secretion causing cytokine storms. The translation of the knowledge on how the resulting systemic inflammation can lead to life-threatening complications into novel treatments and vaccine technologies is underway. Nevertheless, previously existing knowledge on the role of cytoplasmatic or circulating self-DNA as a pro-inflammatory damage-associated molecular pattern (DAMP) was largely ignored. Pathologies reported 'de novo' for patients infected with Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV)-2 to be outcomes of self-DNA-driven inflammation in fact had been linked earlier to self-DNA in different contexts, e.g., the infection with Human Immunodeficiency Virus (HIV)-1, sterile inflammation, and autoimmune diseases. I highlight particularly how synergies with other DAMPs can render immunogenic properties to normally non-immunogenic extracellular self-DNA, and I discuss the shared features of the gp41 unit of the HIV-1 envelope protein and the SARS-CoV 2 Spike protein that enable HIV-1 and SARS-CoV-2 to interact with cell or nuclear membranes, trigger syncytia formation, inflict damage to their host's DNA, and trigger inflammation - likely for their own benefit. These similarities motivate speculations that similar mechanisms to those driven by gp41 can explain how inflammatory self-DNA contributes to some of most frequent adverse events after vaccination with the BNT162b2 mRNA (Pfizer/BioNTech) or the mRNA-1273 (Moderna) vaccine, i.e., myocarditis, herpes zoster, rheumatoid arthritis, autoimmune nephritis or hepatitis, new-onset systemic lupus erythematosus, and flare-ups of psoriasis or lupus. The hope is to motivate a wider application of the lessons learned from the experiences with COVID-19 and the new mRNA vaccines to combat future non-COVID-19 diseases.

Abstract
PURPOSE OF REVIEW Inflammatory Bowel Disease (IBD) is a chronic GI inflammatory condition induced by a dysregulated immune system activation, whereas HIV infection causes depletion of the immune system, inducing immunosuppression. Given the increasing incidence of IBD across the globe, including in developing countries, the co-prevalence of both conditions is expected to increase. Herein, we systematically review the data describing disease course when both pathologies co-exist. RECENT FINDINGS Overall, the co-prevalence of IBD and HIV is around 0.1 to 2%. While IBD does not seem to affect HIV course, the opposite is controversial, as some studies report milder IBD phenotype, with fewer disease relapses especially when CD4 + counts are lower than 200 cells/µL. Despite growing evidence to support the safety of the use of immunosuppressants and biologics in IBD-HIV infected patients, these classes of drugs are used in less than 50% of patients, as compared to non-HIV infected IBD patients. There is a need for more studies on disease course and safety of IBD medications in the setting of IBD.

Abstract
Human immunodeficiency virus (HIV) infection is associated with a myriad of musculoskeletal manifestations. Inflammatory arthritis has been described in association with HIV in both adults and children. Biologic disease-modifying anti-rheumatic drugs, particularly tumor necrosis factor inhibitors (TNFi), have been reported to manage inflammatory arthritis in adults with HIV when conventional therapy fails to control arthritis. In this report, we describe the management of arthritis and enthesitis in a 12-year-old adolescent male with HIV using the TNFi adalimumab. At the time of presentation, the patient was on highly active antiretroviral therapy for 1 year. His viral load was <40 copies/mL, and the CD4+ T-cell count was 1280 cells/mm3 . He had a positive antinuclear antibody and HLA-B27. Rheumatoid factor was negative. After screening for hepatitis B and C and latent tuberculosis, the patient was started on adalimumab. This report describes the successful control of recalcitrant arthritis and enthesitis in a pediatric patient with HIV infection using adalimumab.

Abstract
Ankylosing spondylitis (AS) is an autoinflammatory disease that manifests with the unique feature of enthesitis. Gut microbiota, HLA-B*27, and biomechanical stress mutually influence and interact resulting in setting off a flame of inflammation. In the HLA-B*27 positive group, dysbiosis in the gut environment disrupts the barrier to exogenous bacteria or viruses. Additionally, biomechanical stress induces inflammation through enthesial resident or gut-origin immune cells. On this basis, innate and adaptive immunity can propagate inflammation and lead to chronic disease. Finally, bone homeostasis is regulated by cytokines, by which the inflamed region is substituted into new bone. Agents that block cytokines are constantly being developed to provide diverse therapeutic options for preventing the progression of inflammation. In addition, some antibodies have been shown to distinguish disease selectively, which support the involvement of autoimmune immunity in AS. In this review, we critically analyze the complexity and uniqueness of the pathogenesis with updates on the findings of immunity and provide new information about biologics and biomarkers.

Abstract
Since the introduction of modern antiretroviral treatment for HIV and hepatitis C virus (HCV), the pattern of autoimmune diseases (ADs) in people living with HIV (PWH) might have changed. This is a retrospective study in a cohort of 5,665 PWH at the HIV Clinic of Hospital Universitario La Paz (Spain) to estimate the prevalence of ADs from January 1990 to June 2020. We divided the timeline into four periods: <1996, 1996-2006, 2006-2015, and 2015-2020. In total 369 participants were diagnosed with at least one AD, with a prevalence of 5.3% (95% confidence interval 4.7-5.9). In total, 302 (81%) participants were diagnosed simultaneously or after HIV diagnosis. Most prevalent diseases were immune thrombopenia (IT) (n = 90), cutaneous psoriasis (n = 52), autoimmune thyroid disorders (n = 36), spondylarthritis (n = 24), and inflammatory bowel disease (IBD) (n = 21). There was a significant trend for more ADs in recent periods (p = .037). In recent years, participants with ADs were older, had a long time since HIV diagnosis, and had higher CD4+ T cell count and higher CD4+ T cell nadir (temporal linear trend p < .001). There was a change in the pattern of ADs over time with a decrease in IT and an increase in spondylarthritis, arthritis, IBD, and thyroid disorders. One hundred thirty-nine participants (46%) were coinfected with HCV, with a steady decline throughout the study period. Only cryoglobulinemia was statistically associated with HCV infection. AD increases over time in PWH with reasonable immune virological control. We observed a higher frequency of spondylarthritis, arthritis, autoimmune thyroid disorders, and IBD in recent years.

Abstract
Spondyloarthritis (SpA) refers to a group of diseases with inflammation in joints and spines. In this family, ankylosing spondylitis (AS) is a rare but classic form that mainly involves the spine and sacroiliac joint, leading to the loss of flexibility and fusion of the spine. Compared to other diseases in SpA, AS has a very distinct hereditary disposition and pattern of involvement, and several hypotheses about its etiopathogenesis have been proposed. In spite of significant advances made in Th17 dynamics and AS treatment, the underlying mechanism remains concealed. To this end, we covered several topics, including the nature of the immune response, the microenvironment in the articulation that is behind the disease's progression, and the split between the hypotheses and the evidence on how the intestine affects arthritis. In this review, we describe the current findings of AS and SpA, with the aim of providing an integrated view of the initiation of inflammation and the development of the disease.

Abstract
Background: Patients living with HIV (PLWHIV) can develop autoimmune diseases (AD) needing immunosuppressive treatments (IST). This study aims to describe the impact of IST in PLWHIV. Methods: This was a multicentric retrospective observational study in six HIV referral centers on PLWHIV under IST for AD. Demographic factors, viral co-infections, immunovirological status before and under IST, infectious events, and their descriptions were collected and described focusing on infectious events, immunovirological variations, and IST effectiveness. Results: 9480 PLWHIV were screened for inclusion. Among them, 138 (1.5%) had a history of auto-immune disease, among which 32 (23%) received IST. There was mainly spondyloarthropathy (28%) and the most commonly used IST was methotrexate. The median follow-up under IST was 3.8 years (2.7; 5.9). There were 15 infectious events (0.5 events/individuals) concerning nine patients. At the last medical follow-up, 81% of these were in remission of their AD. Under IST, there was an increase in CD4 during follow-up (629 vs. 827 CD4/mm3, p = 0.04). No HIV virological failure was noted. Conclusions: This study supports a growing evidence base that IST can be used safely and effectively in PLWHIV with careful monitoring.

Abstract
Psoriasis in people living with HIV (PLHIV) has been reported as having particular clinical characteristics. However, most of the source data was derived from descriptive studies in Europe and the USA. This study was conducted to compare the characteristics of psoriasis in PLHIV to general psoriasis patients. We retrospectively reviewed the records of 73 cases of psoriasis in PLHIV and of 232 general psoriasis patients who visited a psoriasis clinic in Bangkok, Thailand. Psoriasis in PLHIV predominated in males (78.1%), with an older age of onset, significantly lower rates of nail involvement and psoriatic arthritis, but higher rates of co-infectious diseases than for general psoriasis patients. A low nadir CD4 T-cell count (<100 cells/μl) and CD4 T-cell count at psoriasis diagnosis were associated with a high body surface area (BSA) involvement. The mean BSA involvement in PLHIV was 24. Although 64.4% (47/73) of the PLHIV had moderate-to-high psoriasis severity, 29.8% of those (14/47) only received topical treatment. Acitretin was the most common drug used. Other therapies were rarely used, and no biologics were administered. In conclusion, psoriasis in PLHIV has several clinical features that differ from general psoriasis. PLHIV tend to receive substandard care for psoriasis, even in upper-middle-income countries.

Abstract
Background: People living with HIV (PLWH) have been shown to have an increased risk of autoimmune diseases. Corticosteroids are the cornerstone of autoimmune diseases treatment, but their use is associated with an increased risk of infections. It is unclear how HIV status affects the risk of infection associated with corticosteroids use. Methods: We conducted a retrospective cohort study from 1991 to 2011, using a medico-administrative database from Quebec. Medical billing codes were used to identify PLWH, and we matched them on age, sex, and index date with up to 4 HIV-negative controls. The exposure of interest was the use of corticosteroids, defined as a systemic corticosteroid dispensation lasting at least 20 days. The outcome of interest was hospitalization for severe infection. Crude and adjusted incidence rates ratios of infection were obtained using a random effect Poisson model, and results were stratified by HIV status. Results: In total, 4798 PLWH were matched to 17 644 HIV-negative controls, among which 1083 (22.6%) PLWH and 1854 (10.5%) HIV-negative controls received at least one course of corticosteroid. The mean duration of corticosteroids use was 4 ± 4.4 months in PLWH and 1.6 ± 5.5 months in HIV-negative controls. The incidence rate ratio (IRR) for infections associated with corticosteroids use was 2.49[1.71–3.60] in PLWH and 1.32[0.71–2.47] in HIV-negative controls (P value for interaction 0.18). The most frequent infections were pulmonary infections (50.4%), followed by urinary tract infections (26%) and opportunistic infections (10.5%). Conclusion: Although our interaction term did not reach significance, the increased risk of infection associated with corticosteroids use was more pronounced in PLWH. However, further research with contemporary data is warranted to confirm if the risk associated with corticosteroids use remains high in PLWH with well-controlled HIV infection.

Abstract
Reports conflict on how HIV infection influences the clinical course of COVID-19. The New York City (NYC) public hospital system provides care for over 14,000 people with HIV, was central in responding to the COVID-19 pandemic, and is therefore in a unique position to evaluate the intersection of these concurrent infections. Retrospective chart review of patients presenting to NYC Health and Hospitals (NYC H+H) diagnosed with COVID-19 infection from March 1, 2020, through April 28, 2020, compared people living with HIV (PLWH) and a propensity-matched (PM) control group of patients without HIV to evaluate associations between HIV status and COVID-19 outcomes. Two hundred thirty-four PLWH presented for COVID-19 testing and 110 (47%) were diagnosed with COVID-19. Among 17,413 patients with COVID-19 and without HIV, 1:n nearest neighbor propensity score matching identified 194 patients matched on age, sex, race, and any comorbidity. In the sample with COVID-19 (N = 304), PLWH (9.1%) had lower rates of mortality than controls [19.1%; PM odds ratio (PM-OR): 0.41, 95% confidence interval (CI): 0.19-0.86]. Among hospitalized COVID-19 patients (N = 179), HIV infection was associated with lower rates of mechanical ventilation (PM-OR: 0.31, 95% CI: 0.11-0.84) and mortality (PM-OR: 0.40, 95% CI: 0. 17-0.95). In the extended pandemic period through April 2021, aggregate data by HIV status suggested elevated hospitalization and mortality rates in PLWH versus people without HIV. These results suggest that the direct biological impacts of the HIV virus do not negatively influence COVID-19-related outcomes when controlling for comorbidity and demographic variables.

Abstract
Background Previous literature on the association between infections and the risk of developing ankylosing spondylitis (AS) presented controversial results. This meta-analysis aimed to quantitatively investigate the effect of infections on the risk of AS. Methods We searched the PubMed, Embase, and Web of Science databases until March 26, 2021 for analytical epidemiological studies on the association between infections and the risk of AS. Fixed or random effect models were used to calculate total risk estimates based on study heterogeneity. Subgroup analysis, and sensitivity analysis were also performed. Publication bias was estimated using funnel plots and Begg’s test. Results Six case-control articles (n=1,296,239) and seven cohort articles (n=7,618,524) were incorporated into our meta-analysis. The pooled odds ratio (OR) from these case-control studies showed that infections were associated with an increased risk of AS (OR=1.46, 95% confidence interval [CI], 1.23–1.73), and the pooled relative risk (RR) from the cohort studies showed the same findings (RR=1.35, 95% CI, 1.12–1.63). Subgroup analysis showed that infections in participants with unadjusted comorbidities (OR=1.66, 95% CI, 1.35–2.03), other types of infection (OR=1.40, 95% CI, 1.15–1.70), and infection of the immune system (OR=1.46, 95% CI, 1.42–1.49) were associated with the risk of AS in case-control studies. In cohort studies, infections with adjusted comorbidities (RR=1.39, 95% CI, 1.15–1.68), viral infection (RR=1.43, 95% CI, 1.22–1.66), other types of infection (RR=1.44, 95% CI, 1.12–1.86), and other sites of infection (RR=1.36, 95% CI, 1.11–1.67) were associated with an increased risk of AS. Conclusions The findings of this meta-analysis confirm that infections significantly increase the risks of AS. This is helpful in providing an essential basis for the prevention of AS via the avoidance of infections.

Abstract
The T-cell receptor (TCR) repertoire is generated in a semistochastic process of gene recombination and pairing of TCRα to TCRβ chains with the estimated total TCR diversity of >108. Despite this high diversity, similar or identical TCR chains are found to recur in immune responses. Here, we analyzed the thymic generation of TCR sequences previously associated with recognition of self- and nonself-antigens, represented by sequences associated with autoimmune diabetes and HIV, respectively. Unexpectedly, in the CD4+ compartment TCRα chains associated with the recognition of self-antigens were generated in significantly higher numbers than TCRα chains associated with the recognition of nonself-antigens. The analysis of the circulating repertoire further showed that these chains are not lost in negative selection nor predominantly converted to the regulatory T-cell lineage. The high abundance of self-reactive TCRα chains in multiple individuals suggests that the human thymus has a predilection to generate self-reactive TCRα chains independently of the HLA-type and that the individual risk of autoimmunity may be modulated by the TCRβ repertoire associated with these chains.
