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
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
BACKGROUND Human immunodeficiency virus (HIV) has a protean clinical picture, in rare instances manifesting as systemic autoimmune disorders such as vasculitides. HIV-induced autoimmune diseases often do not respond well to systemic immunosuppressive therapy. Opportunistic infections may occur in patients with either acquired immunodeficiency syndrome (AIDS) or heavy immunosuppressive treatment, and can further complicate the clinical presentation. CASE PRESENTATION A patient presenting with immunoglobulin A (IgA) vasculitis (IgAV) with treatment-refractory purpuric skin rash and suspect intestinal vasculitis was discovered to have AIDS. HIV was the trigger of IgAV, and cytomegalovirus (CMV) colitis mimicked intestinal vasculitis. Antiretroviral treatment improved both CMV colitis and the control of the autoimmune disease. CONCLUSIONS An autoimmune disease relapsing despite adequate immunosuppressive treatment and/or the presence of recurrent severe opportunistic infections may be clues to an underlying HIV infection.

Abstract
Background Thrombocytopenia is a common hematological manifestation in people living with human immunodeficiency virus (HIV) or acquired immune deficiency syndrome (AIDS; PLWHA). Data on the prognostic relationship and associated factors of thrombocytopenia and HIV infection in China are limited. Objectives We assessed the prevalence of thrombocytopenia, its association with prognosis, and analyzed the associated risk factors among demographic characteristics, comorbidities, hematological and bone marrow indicators. Design We collected patients identified as PLWHA in Zhongnan Hospital. The patients were divided into two groups: the thrombocytopenia group and the non-thrombocytopenia group. We analyzed and compared demographic characteristics, comorbidities, peripheral blood cells, lymphocyte subpopulations, infection indicators, bone marrow cytology, and bone marrow morphology of the two groups. Then we analyzed the risk factors for thrombocytopenia and the effect of platelet (PLT) values on the prognosis of patients. Methods Demographic characteristics and laboratory results were obtained from medical records. In contrast to other studies, we included bone marrow cytology and morphology in this study. Data were analyzed with multivariate logistic regression analysis. The Kaplan-Meier method was used to plot 60-month survival curves for the severe, mild, and non-thrombocytopenia groups. The value p < 0.05 was taken as statistically significant. Results Among 618 identified PLWHA, 510 (82.5%) were male. Overall, thrombocytopenia was found in 37.7% [95% confidence interval (CI): 33.9-41.5%]. Multivariable logistic regression analysis showed that age ⩾40 years [adjusted odds ratio (AOR) 1.869, 95% CI: 1.052-3.320], combined with hepatitis B (AOR 2.004, 95% CI: 1.049-3.826), high procalcitonin (PCT) count (AOR 1.038, 95% CI: 1.000-1.078) were risk factors of thrombocytopenia in PLWHA. An increased percentage of thrombocytogenic megakaryocytes was a protective factor, with an AOR 0.949 (95% CI: 0.930-0.967). Kaplan-Meier survival curve analysis showed that the prognosis was worse in the severe than in the mild (p = 0.002) and non-thrombocytopenia groups (p = 0.008). Conclusion We discovered a general high pervasiveness of thrombocytopenia in PLWHA in China. Age ⩾40 years, combined with hepatitis B virus infection, high PCT, and decreased percentage of thrombocytogenic megakaryocytes indicated a higher risk for developing thrombocytopenia. A PLT count ⩽50 × 109/liter led to a worse prognosis. Therefore, early diagnosis and treatment of thrombocytopenia in these patients are useful.

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
Sarcoidosis is a heterogeneous disease, which can affect virtually every body organ, even though lungs and intra thoracic lymph nodes are almost universally affected. The presence of noncaseating granulomas is the histopathological hallmark of the disease, and clinical picture depends on the organs affected. Data about interaction between sarcoidosis and comorbidities, such as cardiovascular and pulmonary diseases, autoimmune disorders, malignancy and drug-related adverse events are limited. Several lung conditions can be associated with sarcoidosis, such as pulmonary hypertension and fibrosis, making it difficult sometimes the differentiation between complications and distinctive pathologies. Their coexistence may complicate the diagnosis of sarcoidosis and contribute to the highly variable and unpredictable natural history, particularly if several diseases are recognised. A thorough assessment of specific disorders that can be associated with sarcoidosis should always be carried out, and future studies will need to evaluate sarcoidosis not only as a single disorder, but also in the light of possible concomitant conditions.Key messagesComorbidities in sarcoidosis are common, especially cardiovascular and pulmonary diseases.In the diagnostic workup, a distinction must be made between sarcoidosis-related complaints and complaints caused by other separate disorders. It can be very difficult to distinguish between complications of sarcoidosis and other concomitant conditions.The coexistence of multiple conditions may complicate the diagnosis of sarcoidosis, affect its natural course and response to treatment.

Abstract
OBJECTIVE To describe a retrospective review of HIV patients with noninfectious uveitis. Data collected included: demographics, anatomic classification and phenotypic diagnosis of the uveitis, systemic immune-mediated disorders (IMD), time from HIV diagnosis to uveitis, CD4 count, viral load, treatment and complications of treatment and time of follow-up. RESULTS Twenty patients (18 males) were included. The time lag between HIV diagnosis and the onset of uveitis was 9 ± 8.5 years. Mean CD4 count was 670 ± 294 cells/ml. Viral load was undetectable in 14 out of 18 cases. In 6 patients IMD was diagnosed prior to or concurring with the uveitis diagnosis. The use of immunosuppressive therapies was necessary in 6 patients (including biologics in 4 cases). The mean follow-up was 42.2 months. CONCLUSIONS noninfectious uveitis could be the first manifestation of IMD in patients with well-controlled HIV infection. Immunosuppression appeared to be a safe therapeutic option in our cohort of patients.

Abstract
Background People living with human immunodeficiency virus (PLHIV) have a similar prevalence of psoriasis as the general population, though incidence and severity correlate with HIV viral load. Adequately treating HIV early renders the infection a chronic medical condition and allows PLHIV with a suppressed viral load (PLHIV-s) to live normal lives. Despite this, safety concerns and a lack of high-level data have hindered the use of systemic psoriasis therapies in PLHIV-s. Objectives We aim to provide a structured framework that supports healthcare professionals and patients discussing the risks and benefits of systemic psoriasis therapy in PLHIV-s. Our goal was to address the primary question, are responses to systemic therapies for the treatment of psoriasis in PLHIV-s similar to those in the non-HIV population? Methods We implemented an inference-based approach relying on indirect evidence when direct clinical trial data were absent. In this instance, we reviewed indirect evidence supporting inferences on the status of immune function in PLHIV. Recommendations on systemic treatment for psoriasis in PLHIV were derived using an inferential heuristic. Results We identified seven indirect indicators of immune function informed by largely independent bodies of evidence: (1) functional assays, (2) vaccine response, (3) life expectancy, (4) psoriasis manifestations, (5) rate of infections, (6) rate of malignancies, and (7) organ transplant outcomes. Conclusions Drug-related benefits and risks when treating a patient with systemic psoriasis therapies are similar for non-HIV patients and PLHIV with a suppressed viral load and normalized CD4 counts. Prior to initiating psoriasis treatment in PLHIV, HIV replication should be addressed by an HIV specialist. Exercise additional caution for patients with a suppressed viral load and discordant CD4 responses on antiretroviral therapy. Supplementary Information The online version contains supplementary material available at 10.1007/s13555-022-00722-0. People living with human immunodeficiency virus (PLHIV) develop psoriasis as often as everyone else. We asked: what are effective and safe treatments when PLHIV need systemic therapy (pills or injections) for their psoriasis? HIV infection attacks the immune system. When HIV is not treated, the immune system declines. A less effective immune system makes it harder for the body to fight infections and certain cancers. Psoriasis is a skin condition caused by overactive immune cells. Effective psoriasis treatments reduce immune-cell activity. There are some concerns that treatments for psoriasis may not work and could worsen infections or cancers. To answer the question, we gathered 11 dermatologists and 4 HIV specialists. We reviewed the international scientific literature on PLHIV and psoriasis. The absence of direct evidence and volume of information to review made the process challenging. The end results were worthwhile. We concluded that people who are diagnosed early and take antiretroviral therapy to control their HIV infection (PLHIV-c) can live long, healthy lives. Accordingly, we determined that PLHIV-c can likely expect the same safety and efficacy for systemic psoriasis treatments as the general population. Treatment decisions should be made on a case-by-case basis through consultation with the patient and treating physician(s). Pillars of modern medicine are evidence-based care and collaborative decision-making. Too often, neither care provider nor patient are adequately informed. We have tried to fill one information gap for PLHIV and psoriasis. This process may help answer questions in other disease populations where direct evidence is scarce or absent.

Post-Infectious Autoimmunity in the Central (CNS) and Peripheral (PNS) Nervous Systems: An African Perspective. Front Immunol 2022; 13:833548. [PMID: 35356001 PMCID: PMC8959857 DOI: 10.3389/fimmu.2022.833548] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2021] [Accepted: 02/10/2022] [Indexed: 11/13/2022] Open
Abstract
The direct impact and sequelae of infections in children and adults result in significant morbidity and mortality especially when they involve the central (CNS) or peripheral nervous system (PNS). The historical understanding of the pathophysiology has been mostly focused on the direct impact of the various pathogens through neural tissue invasion. However, with the better understanding of neuroimmunology, there is a rapidly growing realization of the contribution of the innate and adaptive host immune responses in the pathogenesis of many CNS and PNS diseases. The balance between the protective and pathologic sequelae of immunity is fragile and can easily be tipped towards harm for the host. The matter of immune privilege and surveillance of the CNS/PNS compartments and the role of the blood-brain barrier (BBB) and blood nerve barrier (BNB) makes this even more complex. Our understanding of the pathogenesis of many post-infectious manifestations of various microbial agents remains elusive, especially in the diverse African setting. Our exploration and better understanding of the neuroimmunology of some of the infectious diseases that we encounter in the continent will go a long way into helping us to improve their management and therefore lessen the burden. Africa is diverse and uniquely poised because of the mix of the classic, well described, autoimmune disease entities and the specifically "tropical" conditions. This review explores the current understanding of some of the para- and post-infectious autoimmune manifestations of CNS and PNS diseases in the African context. We highlight the clinical presentations, diagnosis and treatment of these neurological disorders and underscore the knowledge gaps and perspectives for future research using disease models of conditions that we see in the continent, some of which are not uniquely African and, where relevant, include discussion of the proposed mechanisms underlying pathogen-induced autoimmunity. This review covers the following conditions as models and highlight those in which a relationship with COVID-19 infection has been reported: a) Acute Necrotizing Encephalopathy; b) Measles-associated encephalopathies; c) Human Immunodeficiency Virus (HIV) neuroimmune disorders, and particularly the difficulties associated with classical post-infectious autoimmune disorders such as the Guillain-Barré syndrome in the context of HIV and other infections. Finally, we describe NMDA-R encephalitis, which can be post-HSV encephalitis, summarise other antibody-mediated CNS diseases and describe myasthenia gravis as the classic antibody-mediated disease but with special features in Africa.

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
BACKGROUND AND AIMS Human immunodeficiency virus (HIV) infection is associated with several immune-mediated disorders. However, the risk of inflammatory bowel disease (IBD) in people living with HIV (PLWH) remains unclear. We aimed to assess the risk of IBD among PLWH using a nationwide, population-based Danish cohort and to validate findings in a large American insurance-based database. METHODS Using Danish registries (1983-2018), we identified 8995 PLWH and age- and sex-matched them to 449,750 HIV-negative individuals. Cox regression analysis was undertaken to calculate hazard ratios (HRs) with 95% confidence intervals (CIs) for IBD diagnosis. Results were stratified by sex, age, and year of HIV diagnosis. Using an American insurance-based cohort, Explorys (1999-2018), we assessed the prevalence odds ratio (OR) and 95% CI of IBD diagnosis in PLWH compared with HIV-negative individuals. RESULTS IBD diagnosis among PLWH in Denmark was increased (HR: 2.25, 95% CI: 1.78-2.83) compared with matched HIV-negative individuals. This was seen for both Crohn's disease (HR: 2.25, 95% CI: 1.47-3.44) and ulcerative colitis (HR: 2.24, 95% CI: 1.70-2.96) and in male (HR: 2.75, 95% CI: 2.15-3.52) but not female (HR: 0.93, 95% CI: 0.48-1.79) PLWH. Explorys analysis also showed an increased odds of IBD diagnoses among PLWH (OR: 1.41; 95% CI: 1.35-1.49). CONCLUSION This study finds an increased risk of IBD diagnosis among PLWH in both a Danish and US cohort, highlighting a need to consider IBD in PLWH with new-onset gastrointestinal symptoms. Further research into the role of antiretroviral therapy in this relationship is required.

Abstract
PURPOSE OF REVIEW Sarcoidosis is a complex granulomatous disease of unknown cause. Several drug categories are able to induce a systemic granulomatous indistinguishable from sarcoidosis, known as drug-induced sarcoidosis-like reaction (DISR). This granulomatous inflammation can resolve if the medication is discontinued. In this review, we discuss recent literature on medication associated with DISR, possible pathophysiology, clinical features, and treatment. RECENT FINDINGS Recently, increasing reports on DISR have expanded the list of drugs associated with the systemic granulomatous eruption. Most reported drugs can be categorized as combination antiretroviral therapy, tumor necrosis factor-α antagonist, interferons, and immune checkpoint inhibitors, but reports on other drugs are also published. The proposed mechanism is enhancement of the aberrant immune response which results in systemic granuloma formation. It is currently not possible to know whether DISR represents a separate entity or is a triggered but 'true' sarcoidosis.As DISRs may cause minimal symptoms, treatment is not always necessary and the benefits of continuing the offending drug should be weighed against clinical symptoms and organ dysfunction. Treatment may involve immunosuppressive medication that is used for sarcoidosis treatment. SUMMARY In this article, we review recent insights in DISR: associated drug categories, clinical presentation, diagnosis, and treatment. Additionally, we discuss possible mechanisms of DISR which can add to our knowledge of sarcoidosis pathophysiology.

Abstract
OBJECTIVE To assess the incidence, presentation, and management of RA in persons with HIV (PWH), including use of disease-modifying anti-rheumatic drugs (DMARDs) in this immunosuppressed population. METHODS Patients were included from the Veterans Aging Cohort Study, a longitudinal cohort of Veterans with HIV and matched uninfected Veterans. We identified patients with ≥1 rheumatologist-generated International Classification of Diseases (ICD) code for RA and a measurement of rheumatoid factor (RF) or anti-CCP antibodies. Charts were reviewed using the 2010 RA Classification Criteria to identify incident RA. We recorded use and adverse effects of DMARDs during the first contiguous (no interruption greater than 6 months) course. RESULTS We included 56,250 PWH and 116,944 uninfected persons over 2,384,541 person-years. Of 2,748 patients with an RA ICD code, incident RA was identified in 215 patients, including 21 PWH. The incidence rate ratio of RA in PWH vs. uninfected was 0.29 (95% CI 0.19-0.48). Most patients (88%) with RA were seropositive. However, high autoantibody titers were less common in PWH: 5% (1/21) of PWH had both high titer anti-CCP and RF, compared to 41% (82/194) of uninfected. DMARDs were prescribed for 71% (15/21) of PWH with RA, compared to 94% (183/194) of uninfected. Among 10 PWH prescribed DMARDs, we found no signal for worse infectious safety profile compared to 158 HIV-negative controls. CONCLUSION Incident RA was less common in PWH than in matched controls. PWH with incident RA had less positive autoantibody profiles than controls and were prescribed DMARDs less frequently.

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.

Abstract
Background: HIV infection results in immune homeostasis perturbations, which is characterized by CD4+ T-cell depletion, immune activation, and inflammation. Effective antiretroviral therapy (ART) does not fully restore immunologic and clinical health in people living with HIV (PLWH). Various drugs have been used to improve their immune status and CD4+ T-cell counts, but no measures have been tested effective. Here we conduct a systematic review and meta-analysis of existing clinical studies on improving CD4+ T-cell count while decreasing inflammation and immune activation. Methods: We retrieved possible relevant publications from a total of five electronic databases and selected eligible studies, which dealt with outcomes of medical therapy for CD4+ T-cell count recovery, inflammation, and immune activation with or without ART. We paid particular attention to immunologic non-responders with a favorable treatment regimen. Results: Thirty-three articles were included in the systematic review and meta-analysis. However, there were no safe and effective medications specific for improving CD4+ T-cell reconstitution. The immunological benefits or adverse events mainly depend on the safety, dosage, and duration of the candidate medication use, as well as whether it is combined with ART. Conclusion: Under the “safe, combined, adequate and long (SCAL)” principles, alternative approaches are needed to accelerate the recovery of CD4+ T-cells, and to prevent adverse long-term outcomes in PLWH with standard ART treatment.

Abstract
A causal link between viral infections and autoimmunity has been studied for a long time and the role of some viruses in the induction or exacerbation of systemic lupus erythematosus (SLE) in genetically predisposed patients has been proved. The strength of the association between different viral agents and SLE is variable. Epstein-Barr virus (EBV), parvovirus B19 (B19V), and human endogenous retroviruses (HERVs) are involved in SLE pathogenesis, whereas other viruses such as Cytomegalovirus (CMV) probably play a less prominent role. However, the mechanisms of viral-host interactions and the impact of viruses on disease course have yet to be elucidated. In addition to classical mechanisms of viral-triggered autoimmunity, such as molecular mimicry and epitope spreading, there has been a growing appreciation of the role of direct activation of innate response by viral nucleic acids and epigenetic modulation of interferon-related immune response. The latter is especially important for HERVs, which may represent the molecular link between environmental triggers and critical immune genes. Virus-specific proteins modulating interaction with the host immune system have been characterized especially for Epstein-Barr virus and explain immune evasion, persistent infection and self-reactive B-cell "immortalization". Knowledge has also been expanding on key viral proteins of B19-V and CMV and their possible association with specific phenotypes such as antiphospholipid syndrome. This progress may pave the way to new therapeutic perspectives, including the use of known or new antiviral drugs, postviral immune response modulation and innate immunity inhibition. We herein describe the state-of-the-art knowledge on the role of viral infections in SLE, with a focus on their mechanisms of action and potential therapeutic targets.

New Insights in Autoimmune Hemolytic Anemia: From Pathogenesis to Therapy Stage 1. J Clin Med 2020; 9:jcm9123859. [PMID: 33261023 PMCID: PMC7759854 DOI: 10.3390/jcm9123859] [Citation(s) in RCA: 47] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Revised: 11/20/2020] [Accepted: 11/24/2020] [Indexed: 12/15/2022] Open
Abstract
Autoimmune hemolytic anemia (AIHA) is a highly heterogeneous disease due to increased destruction of autologous erythrocytes by autoantibodies with or without complement involvement. Other pathogenic mechanisms include hyper-activation of cellular immune effectors, cytokine dysregulation, and ineffective marrow compensation. AIHAs may be primary or associated with lymphoproliferative and autoimmune diseases, infections, immunodeficiencies, solid tumors, transplants, and drugs. The direct antiglobulin test is the cornerstone of diagnosis, allowing the distinction into warm forms (wAIHA), cold agglutinin disease (CAD), and other more rare forms. The immunologic mechanisms responsible for erythrocyte destruction in the various AIHAs are different and therefore therapy is quite dissimilar. In wAIHA, steroids represent first line therapy, followed by rituximab and splenectomy. Conventional immunosuppressive drugs (azathioprine, cyclophosphamide, cyclosporine) are now considered the third line. In CAD, steroids are useful only at high/unacceptable doses and splenectomy is uneffective. Rituximab is advised in first line therapy, followed by rituximab plus bendamustine and bortezomib. Several new drugs are under development including B-cell directed therapies (ibrutinib, venetoclax, parsaclisib) and inhibitors of complement (sutimlimab, pegcetacoplan), spleen tyrosine kinases (fostamatinib), or neonatal Fc receptor. Here, a comprehensive review of the main clinical characteristics, diagnosis, and pathogenic mechanisms of AIHA are provided, along with classic and new therapeutic approaches.

Incidence of autoimmune diseases in people living with HIV compared to a matched population: a cohort study. Clin Rheumatol 2020; 40:2439-2445. [PMID: 33230683 DOI: 10.1007/s10067-020-05500-x] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 10/26/2020] [Accepted: 11/04/2020] [Indexed: 10/22/2022]
Abstract
The objective of this paper is to estimate incidence and relative risk of autoimmune conditions in patients living with HIV compared to an HIV-negative matched population. We conducted a retrospective study in the medico-administrative database of the province of Québec, Canada. All HIV-positive patients treated with antiretrovirals were matched to up to 4 HIV-negative controls for age, sex, and period of follow-up. The following autoimmune conditions were identified using medical billing codes: vasculitis, hematological (immune thrombocytopenic purpura and immune hemolytic anemia), ankylosing spondylitis, psoriasis and psoriatic arthritis, inflammatory bowel disease and associated arthritis, connectivitis, and systemic lupus erythematosus. Incidence rates and adjusted hazard ratios (aHR) were obtained using survival models. A total of 4245 HIV-positive patients were matched to 16493 HIV-negative patients. Autoimmune diseases were diagnosed in 407 (9.6%) HIV-positive and 508 (3%) HIV-negative patients. The aHR for autoimmune diseases associated to HIV was 2.40 95% CI [2.10-2.75]. The strongest associations were seen for hematological disorders (aHR 8.34 95% CI [6.13-11.36]), followed by ankylosing spondylitis (1.82 95% CI [1.03-3.21]), inflammatory bowel disease and associated arthritis (1.80 95% CI [1.37-2.35]), psoriasis and associated arthritis (1.69 95% CI [1.23-2.33]), and rheumatoid arthritis (1.51 95% CI [1.08-2.11]).We found no association between HIV and the incidence of vasculitis, connectivitis, and systemic lupus erythematosus, but the number of cases for these diseases were few. Autoimmune diseases are more frequent among people living with HIV than age and sex-matched population-based controls. Key Points • Strength: The major strength of this study is its large sample size of 4200 people treated as HIV infection, matched to 16000 HIV negative for sex and age. • Novelty: We found that people living with HIV were more than twice as likely to suffer from auto-immune diseases than their matched counterparts.

Abstract
Purpose of Review To review the spectrum of vasculitides in HIV-infected patients and to identify the clinical features that characterize vasculitis in sero-positive HIV. Recent Findings Epidemiological studies conducted in the post-HAART era described the rarity of vasculitis in the setting of HIV-infected patients. A study identified histopathological features such as leukocytoclastic vasculitis of the vasa vasorum and adventitial inflammation in the large artery pathology of HIV-positive patients compared with HIV-negative patients with critical lower limb ischemia. A recent retrospective cohort study reported that HIV-positive patients with LVV developed more vascular complications, responded less to antiretroviral therapy, and had worse outcome than HIV-negative patients with LVV. Summary Vasculitides continue to be a rare disease in patients with HIV. The spectrum of vasculitis ranges from life-threatening conditions to relatively mild skin conditions. Recognizing vasculitis in the setting of HIV-positive patients is important because sometimes it require immunosuppressive treatment.

Abstract
OBJECTIVE Psoriasis is a T-cell-mediated inflammatory disease with genetic factors involved in its etiopathogenesis. In non-HIV populations, HLA-B57:01 has been associated with a higher risk of psoriasis. The aim of this study was to investigate demographic and immunovirological characteristics associated with psoriasis, and to assess whether HLA-B57:01 is associated with psoriasis among people living with HIV (PLHIV) followed in a large French multicenter Dat'AIDS cohort. METHODS All PLHIV followed up from January 2000 to December 2018 with an available result for HLA-B57:01 were included. Logistic regression models were used to identify associations between psoriasis (outcome variable) and explanatory variables. RESULTS Among 31 076 PLHIV, the overall prevalence of psoriasis and HLA-B57:01 were 2.25 and 4.73%, respectively and varied according to ethnicity. By multivariate analysis, male gender [OR 1.81 (95% CI 1.46-2.24), P < 10], positive HLA-B57:01 [OR 2.66 (95% CI 2.12-3.33), P < 10], nadir CD4 cell count less than 200 cells/μl [OR 1.41 (95% CI 1.19-1.67), P < 10] and positive HCV serology [OR 1.45 (95% CI 1.20-1.76), P < 10] were significantly associated with a higher risk of psoriasis. Being born in West and Central Africa [OR 0.15 (95% CI 0.10-0.25), P < 10], the Caribbean islands [OR 0.14 (95% CI 0.05-0.45), P = 0.0008] or Latin America [OR 0.31 (95% CI 0.14-0.69), P = 0.004] was associated with a lower risk of psoriasis compared with patients born in mainland France. CONCLUSION PLHIV carrying HLA-B57:01 have around a three-fold increased risk of psoriasis. This association might provide a possible explanation for the observed differences in psoriasis prevalence between ethnic groups.

Abstract
INTRODUCTION Autoimmune hemolytic anemia (AIHA) is due to autoantibodies against erythrocytes that may arise either because of primary tolerance breakage or along with several associated conditions, including genetic predispositions, congenital syndromes, environmental triggers, autoimmune diseases, immunodeficiencies, and neoplasms. AREAS COVERED This review evaluated the risk of AIHA development in associated conditions and summarized disease-intrinsic risk factors for relapse and outcome. Diagnostic procedures were analyzed to properly identify primary and secondary forms. A Medline including clinical trials, meta-analyses, guidelines, consensus, and case reports, published in the last 30 years were performed. EXPERT OPINION The several associated conditions listed above constitute a risk for AIHA development and should be considered since disease course and therapy may be different. Particularly, AIHA developing after transplant or novel checkpoint inhibitors is an emerging complex entity whose proper therapy is still an unmet need. Concerning intrinsic risk factors, the severity of anemia at onset correlated with the recurrence of relapses, refractoriness, and fatal outcome. This finding reflects the presence of several mechanisms involved in AIHA, i.e. highly pathogenic antibodies, complement activation, and failure of marrow compensation. With the advent of novel target therapies (complement and various tyrosine kinase inhibitors), a risk-adapted therapy for AIHA is becoming fundamental.

Abstract
The pathogenesis of systemic lupus erythematosus (SLE) is characterised by the hyper-activation of immunologic pathways related to the antiviral response. Exogenous and endogenous retroviruses, by integrating their DNA templates in the host cell genome, may epigenetically control the transcription of genes involved in the immune response. Furthermore, their nucleic acids or neo-synthesized proteins could stimulate the sensor molecules placed upstream the inflammatory cascade. Exogenous retroviruses, like human immunodeficiency virus, have been associated to SLE-like manifestations or to a fair SLE diagnosis. In addition, there is some evidence confirming a pathogenic role of human endogenous retroviruses in SLE. In line with these data, the use of antiretroviral agents could represent an attractive opportunity in the future therapeutic algorithms of this disease, but studies are still missing.

Abstract
Rheumatic manifestations remain an important clinical manifestation associated to HIV. To date after 4 decades of the onset of the HIV/AIDS pandemic, almost 37 million individuals are living with the infection, including close to 2 million of newly infected individuals. The status, however, of a considerable proportion of HIV/AIDS patients has changed from a near fatal disorder secondary to opportunistic infections to a chronic disease in which renal cardiovascular, diabetes, malignancy, and autoimmune co-morbid disorders have become prevalent and relevant. In addition, the spectrum of rheumatic disorders also has changed since the introduction of HAART and its diagnosis and treatment represents a challenge. The purpose of this review is to define and discuss the HIV-related rheumatic manifestations in the pre- and post-HAART eras.

Abstract
BACKGROUND Hepatitis C virus (HCV) and HIV infections are associated with higher risk of autoimmune diseases and T-cell dysfunction. SETTING We evaluate prevalence and factors associated with the presence of autoimmune antinuclear (ANA), anti-smooth muscle actin (aSMA), and anti-liver kidney microsome (aLKM1) antibodies (Ab) in HCV/HIV-coinfected patients during the post-combined antiretroviral therapy era. METHODS A cross-sectional observational study nested in the ANRS CO13 HEPAVIH cohort (NCT number: NCT03324633). We selected patients with both ANA testing and T-cell immunophenotyping determination during the cohort follow-up and collected aLKM1 and aSMA data when available. Logistic regression models were built to determine factors associated with the presence of auto-Ab. RESULTS Two hundred twenty-three HCV/HIV-coinfected patients fulfilled selection criteria. Prevalence of ANA and aSMA was 43.5% and 23.2%, respectively, and both were detected in 13.3% of patients. Isolated aSMA were detected in 9.9% and aLKM1 in 2 patients. In multivariable analysis, only a low nadir CD4 T-cell count was significantly associated with ANA detection. CONCLUSIONS ANA and aSMA detection remain frequent in HCV/HIV-coinfected patients during the post-combined antiretroviral therapy era, despite fair immune restoration. These results advocate for a close monitoring of ANA before immune checkpoint inhibitor therapy in these patients with greater caution for those with a low nadir CD4 T-cell count.

Abstract
Spondyloarthritis (SpA) is a group of associated chronic systemic inflammatory immune-mediated rheumatic diseases affecting axial and peripheral joints and entheses. The aim of the present study was to identify what parameters are useful to determine in order to better understand the correlation between the disease activity/severity and the microbiological results/immune status against intestinal and/or urogenital pathogens. Microorganisms known to trigger SpA, including Klebsiella spp., Yersinia spp., Salmonella spp., Campylobacter spp. and Chlamydia spp., were analyzed in various specimens (stool, urine, synovial fluid and serum) collected from 27 randomly selected SpA patients and 26 healthy controls using a combined direct and indirect approach relying on conventional culture technique and nucleic acid-based assays together with serological testing by ELISA. Although Escherichia coli derived from phylogroup A prevailed in the gut microflora of the patients and controls, differences were observed regarding the representatives of the other phylogroups with a higher prevalence of E.coli members of phylogenetic group B1 in the stool specimens of patients. Antibodies against the targeted species were detected in SpA patients and controls, and the serological profiles of the former were more diverse and complex. In conclusion, the detection of anti-bacterial antibodies combined with other specific laboratory investigations should be more extensively used to monitor SpA patients in association with their symptoms and in order to determine and administer more effective therapeutics.

Abstract
Psoriasis is a prevalent systemic immune-mediated disease with cutaneous manifestations. In HIV-infected patients, psoriasis may have a higher incidence, present atypical and more exuberant clinical features, and is frequently recalcitrant to treatment. Despite this aggravated severity, treatment options for psoriasis in HIV-infected individuals remain limited due to the risk of fatal immunosuppression associated with both classical immunosuppressants and new biological drugs. Notwithstanding, drug therapy in psoriasis has been undergoing major advances for the last few years, with novel drugs approved, which could significantly add to the management of HIV-infected patients. It is therefore our aim to present a review of the available literature to highlight the updated evidence on psoriasis in HIV-infected individuals, particularly in regards to its epidemiology, proposed pathophysiology, clinical presentation, currently available therapeutic options, and future perspectives.

Abstract
BACKGROUND Increased autoreactive antibodies have been reported in HIV disease; however, the mechanism accounting for autoantibody induction in HIV remains unknown. RESULTS Herein, we show that seasonal influenza vaccination induces autoantibody production (e.g., IgG anti-nuclear antibody (ANA) and anti-double-stranded DNA antibody (anti-dsDNA)) in some viral-suppressed antiretroviral therapy (ART)-treated HIV+ subjects, but not in healthy controls. These autoantibodies were not derived from antigen-specific B cells but from activated "bystander" B cells analyzed by single-cell assay and by study of purified polyclonal ANAs from plasma. To explore the mechanism of autoantibody generation in HIV+ subjects, plasma level of microbial products, gene expression profile of B cells, and B cell receptor (BCR) repertoires were analyzed. We found that autoantibody production was associated with increased plasma level of microbial translocation; the patients with high autoantibodies had skewed B cell repertoires and upregulation of genes related to innate immune activation in response to microbial translocation. By analyzing circulating microbial 16S rDNA in plasma, the relative abundance of Staphylococcus was found to be associated with autoantibody production in HIV+ subjects. Finally, we found that injection of heat-killed Staphylococcus aureus promoted germinal center B cell responses and autoantibody production in mice, consistent with the notion that autoantibody production in HIV+ patients is triggered by microbial products. CONCLUSIONS Our results showed that translocation of Staphylococcus can promote B cell activation through enhancing germinal center response and induces autoantibody production. It uncovers a potential mechanism linking microbial translocation and autoimmunity in HIV+ disease and provides a strong rationale for targeting Staphylococcus to prevent autoantibody production.

Abstract
Emerging and reemerging viral infections have been a characteristic feature of the past several decades, with HIV infection being the most important example of an emergent viral infection. To date, the status of a considerable proportion of HIV/AIDS patients has changed from a near-fatal disorder secondary to opportunistic infections to a chronic disease in which a variety of co-morbid conditions have become prevalent and relevant. Arthralgia and myalgias are the most common symptoms. The rate of spondyloarthritis varies according to the geographic area, genetic and mode of transmission. Most RA and SLE patients might go into remission after the development of AIDS, but also there are patients that continue with active disease. Prevalence of DILS is highest among African Americans in less advanced stages. PAN is clinically less aggressive and peripheral neuropathy is the most common clinical manifestation. Anti-phospholipid syndrome (APS), systemic sclerosis and poly-dermatomyositis are uncommon. After the introduction of combination antiretroviral therapy (cART), a decline of spondyloarthritis disorders and of DILS and development of new syndromes such as IRIS, osteoporosis and avascular bone necrosis have occurred. The treatment of patients with rheumatic diseases and HIV infection remains a challenge.

Polak D, Shmueli A, Brenner T, Shapira L. Oral infection with P. gingivalis exacerbates autoimmune encephalomyelitis. J Periodontol 2018; 89:1461-1466. [PMID: 30030849 DOI: 10.1002/jper.17-0531] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2017] [Revised: 05/26/2018] [Accepted: 05/27/2018] [Indexed: 12/12/2022]
Abstract
BACKGROUND Oral infection of mice with P. gingivalis induces periodontal inflammation and attachment loss. The aim of the present study was to investigate whether infection of mice with P. gingivalis, exacerbates the clinical course of experimental autoimmune encephalomyelitis (EAE)-a mouse model of multiple sclerosis (MS). METHODS Induction of EAE was carried out by immunization of C57BL/6 mice with myelin oligodentrocyte glycoprotein (MOG35-55 ). P. gingivalis infection was induced via subcutaneous chambers model and the oral gavage. The severity of EAE was measured using a clinical severity score. Ex-vivo reactivation of lymphocytes with the encephalitogenic peptide MOG35-55 was also tested. RESULTS Subcutaneous as well as oral infection with live P. gingivalis led to significant aggravation of the severity of EAE. Lymph node cells harvested from mice with EAE following P. gingivalis infection showed augmented lymphocyte proliferation towards the encephlatigenic MOG moiety compared to mice with EAE only. CONCLUSIONS The present results indicate that oral infection with P. gingivalis augmented the severity of EAE. This may stem from the systemic pro-inflammatory response triggered by P. gingivalis infection or via antigen mimicking. The present study provides evidence that periodontal infection may play a role as modifier in CNS inflammatory disorders, such as MS.
