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.

Systemic lupus erythematosus in the setting of HIV-1 infection: a longitudinal analysis. Clin Rheumatol 2020; 39:413-418. [PMID: 31897958 DOI: 10.1007/s10067-019-04867-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2019] [Revised: 10/31/2019] [Accepted: 11/20/2019] [Indexed: 10/25/2022]
Abstract
Patients with concomitant HIV-1 infection and systemic lupus erythematosus (SLE) followed longitudinally at an HIV outpatient clinic from 1994 to 2019 were examined. Patients met 1982 and 1997 ACR classification criteria for SLE at the Thomas Street clinic from 1994 to 2019. Clinical and demographic comparisons were made with a non HIV-SLE patient cohort, the Lupus in Minorities Studies, Nature versus Nurture (LUMINA) study. Twenty-two patients with concomitant HIV-1 infection and SLE were identified, including 18 females, 3 males, and 1 male to female transgender. Overall, 81.8% of SLE-HIV patients were African-American compared to 55.3% of the 5856 patients seen at the HIV clinic from 2016 to 2017 (p = 0.02, OR = 3.6). There were 12 patients that developed HIV-1 in the setting of SLE and 10 patients that developed SLE in the setting HIV-1. This demographic distribution was significant when compared with the 1604 unique patients in the HIV rheumatology clinic from 1994 to 2019 (p = 0.03, OR = 5.9) and also significant when compared with the 5856 patients attending the county HIV clinic overall in 2016-2017 (p = 0.008, OR = 7.2). When comparing with the non-HIV SLE cohort, anti-dsDNA antibodies were noted less frequently in all HIV-SLE patients (p = 0.0002) including all sub-cohorts of our patients. Skin/mucosal involvement (p = 0.0003) and cytopenias (p = 0.0001) occurred less frequently in the patients that were diagnosed with HIV after their SLE diagnosis compared to non-HIV SLE patients. In a large county HIV clinic setting, the prevalence of SLE was significantly higher in African American women. Anti-dsDNA antibodies were less frequent in HIV-1 positive SLE patients.Key Points• This paper presents clinical and laboratory data on the largest cohort of SLE patients with HIV-1 infection reported to date.• The prevalence of SLE in a large outpatient HIV-1 clinic was larger than reported in HIV negative population studies.• The prevalence of SLE was particularly high in black HIV-1 infected women.• Skin/mucosal involvement and anti-ds DNA antibodies were less common in patients with HIV-1 and SLE compared to patients with SLE without SLE>.

Abstract
Systemic lupus erythematosus flares when genetically predisposed people encounter environmental agents that cause oxidative stress, such as infections and sunlight. How these modify the immune system to initiate flares is unclear. Drug induced lupus models demonstrate that CD4+ T cells epigenetically altered with DNA methylation inhibitors cause lupus in animal models, and similar T cells are found in patients with active lupus. How infections and sun exposure inhibit T cell DNA methylation is unclear. DNA methylation patterns are replicated each time a cell divides in a process that requires DNA methyltransferase one (Dnmt1), which is upregulated as cells enter mitosis, as well as the methyl donor S-adenosylmethionine, created from dietary sources. Reactive oxygen species that inhibit Dnmt1 upregulation, and a diet poor in methyl donors, combine to cause lupus in animal models. Similar changes are found in patients with active lupus, indicating a mechanism contributing to lupus flares.

Abstract
RATIONALE Coexisting systemic lupus erythematosus (SLE) and human immunodeficiency virus (HIV) infection cases are rare worldwide. Great challenges are posed on the diagnosis and treatment of such concurrent cases. PATIENT CONCERN We report the case of a 44-year-old Chinese man with edema, hematuria, and fever who presented at West China Hospital, Sichuan University, Chengdu, Sichuan, China, in 2013. DIAGNOSES An initial diagnosis of SLE was made from the clinical manifestations and laboratory findings based on the Systemic Lupus International Collaborating Clinics classification criteria. Immunosuppressant therapy relieved him of the edema and hematuria, but he regained the symptoms after a cold. Workup, including electrochemiluminescence immunoassay, western blot, and polymerase chain reaction analysis, revealed that he was concurrently infected with HIV after hospitalization. INTERVENTIONS The treatment plan included methylprednisolone and cyclophosphamide, with gastroprotective and hepatoprotective agents, simultaneously aiming to reduce urinary protein. After HIV infection confirmed, cyclophosphamide was stopped. He was referred to the local Centers for Disease Control and Prevention for combination antiretroviral therapy (ART). He was suggested to continue monitoring CD4 T-cell count for an appropriate dose of immunosuppressive drugs. OUTCOMES In the last follow-up in May 2017, he had been stable in terms of both SLE and HIV infection. LESSONS The case highlights the presence of concurrent SLE and HIV infection. Laboratory technicians and clinicians should be cautious on diagnosis, especially in eliminating the false-positive results. Attention should be paid to the dose of immunosuppressants and the ART procedure.

Abstract
At the end of 2013, 35 million people worldwide were infected with HIV. The prognosis of HIV has been transformed by combination antiretroviral therapy (cART). Providing compliance is good, the use of cART has normalised the life expectancy of HIV-infected people leading to a growing population of people with chronic infection. Management of HIV patients has therefore needed to adapt in order to not only control viral activity but also manage long-term complications of HIV and cART. Rheumatological manifestations of HIV were first described in 1989. Since then, there have been case reports, case series and epidemiological studies describing different clinical manifestations of HIV in the musculoskeletal system. This review will encompass musculoskeletal pain, fibromyalgia, systemic lupus erythematosus (SLE) and inflammatory arthritis in HIV. We will aim to report on the prevalence of these conditions and the risk factors, explore the impact of the virus on the clinical presentations and discuss implications for diagnosis and management.

Abstract
UNLABELLED Systemic lupus erythematosus (SLE) is rarely reported in association with HIV infection. We describe two unpredictable cases and provide a review of the literature. Retrospective analysis of the medical records of two HIV-infected patients diagnosed with SLE and admitted at Luigi Sacco Hospital (Milano, Italy). Search of the literature from 1981 to 2012 and review of the cases reported. Case 1: a 32-year-old HIV-infected African woman who developed a SLE flare after re-introduction of antiretroviral therapy (ART). The flare was characterized by bullous skin eruption and membranous glomerulonephritis. Case 2: a 44-year-old Caucasian woman, admitted to our hospital because of lacunar stroke: HIV infection and SLE were simultaneously diagnosed. LITERATURE 55 cases of SLE in the setting of HIV infection were reported. Forty-five patients met the requirements of the American College of Rheumatology for the diagnosis of SLE. The diagnosis of SLE preceded HIV infection in six patients. On the contrary, in 29 patients, HIV infection was reported before SLE. Median CD4+ count at SLE diagnosis was 361 cells/μl. A SLE manifestation following ART immune recovery was documented in 18.2% of the cases. On the contrary, the progression of HIV infection paralleled with SLE remission in 22.5% of the patients. The study shows that an autoimmune disease such as SLE can occur despite the loss of immunocompetence caused by HIV infection. Moreover, SLE and HIV infection influence each other possibly through immunologic mechanisms determining awkward manifestations.

Abstract
The coexistence of human immunodeficiency virus (HIV) infection and systemic lupus erythematosus (SLE) is unusual, but the occurrence of SLE after HIV infection is even less common. Both conditions share similar clinical features including constitutional symptoms, facial rash, oral ulcers, alopecia, arthralgias, arthritis, seizures, cytopenias, glomerulonephritis, and antinuclear and antiphospholipid antibodies. This clinical overlap makes the diagnosis of SLE in a patient with pre-existing HIV infection difficult. Furthermore, immune complex glomerulonephritis with features resembling lupus nephritis has been described in HIV-positive patients. We present the case of a 45-year-old Hispanic woman with long-standing HIV infection who developed membranous glomerulonephritis with histological features of lupus nephritis. Five years after onset of renal disease she developed clinically evident SLE.

Abstract
We present the case of a young black African woman living in the UK who presented with systemic lupus erythematosus (SLE) and HIV. The reported coexistence of HIV and SLE is unusual with fewer than 30 published cases. We discuss some of the clinical and diagnostic challenges that face clinicians when a patient presents with both conditions. In particular, we discuss the overlap in symptoms, signs and laboratory findings, and the difficulties that this may pose in terms of making a diagnosis. The implications that having a dual diagnosis may have for treating each condition are also discussed. With increased HIV testing in a variety of clinical settings there is likely to be an increase in detection of similar cases. This case emphasizes the need for careful diagnostic testing and judicious interpretation of the validity of laboratory results in order to reach an accurate diagnosis in such patients.

Abstract
The parent-into-F1 model has led to important advances in our understanding of lupus. Here, we review the work in murine lupus that elucidated the role of T cells and supported the conclusion that the parent-into-F1 model of induced lupus compares favorably with de facto gold standard spontaneous models of lupus. Then we focus on recent work in parent-into-F1 mice, which has yielded novel insights into unresolved controversies, such as the role of apoptosis in the pathogenesis of lupus and lupus in patients receiving TNF blockade. Finally, the review considers the evidence that supports a potential role for CD8 T cells, both cytotoxic and memory cells, in mediating disease remission.

Abstract
Fas-mediated apoptosis is an important contributor to contraction of Ag-driven T cell responses acting only on activated Ag-specific T cells. The effects of targeted Fas deletion on selected cell populations are well described however little is known regarding the consequences of Fas deletion on only activated Ag-specific T cells. We addressed this question using the parent-into-F(1) (P-->F(1)) model of acute or chronic (lupus-like) graft-vs-host disease (GVHD) as a model of either a CTL-mediated or T-dependent B cell-mediated response, respectively. By transferring Fas-deficient lpr donor T cells into Fas-intact F(1) hosts, the in vivo role of Ag-specific T cell Fas can be determined. Our results demonstrate a novel dichotomy of Ag-specific T cell Fas function in that: 1) Fas expression on Ag-activated T cells has costimulatory, helper, and down-regulatory roles in vivo and 2) these roles were observed only in a CTL response (acute GVHD) and not in a T-dependent B cell response (chronic GVHD). Specifically, CD4 T cell Fas expression is important for optimal CD4 initial expansion and absolutely required for help for CD8 effector CTL. Donor CD8 T cell Fas expression played an important but not exclusive role in apoptosis and down-regulation. By contrast, CD4 Fas expression played no detectable role in modulating chronic GVHD induction or disease expression. These results demonstrate a novel role for Ag-specific T cell Fas expression in in vivo CTL responses and support a review of the paradigm by which Fas deficiency accelerates lupus in MRL/lpr lupus-prone mice.

Abstract
Many rheumatic diseases have been observed in HIV-infected persons. We, therefore, conducted a comprehensive literature search in order to review the prevalence, presentation and pathogenesis of rheumatic manifestations in HIV-infected subjects. Articular conditions (arthralgia, arthritis and SpAs) are either caused by the HIV infection itself, triggered by adaptive changes in the immune system, or secondary to microbial infections. Muscular symptoms may result from rhabdomyolysis, myositis or from side-effects of highly active anti-retroviral therapy (HAART). Osseous complications include osteonecrosis, osteoporosis and osteomyelitis. Some conditions such as the diffuse infiltrative lymphocytosis syndrome and sarcoidosis affect multiple organ systems. SLE may be observed but may be difficult to differentiate from HIV infection. Some anti-retroviral agents can precipitate hyperuricaemia and are associated with arthralgia. When indicated, immunosuppressants and even anti-TNF-alpha agents can be used in the carefully monitored HIV patient. Thus, rheumatic diseases and asymptomatic immune phenomena remain prevalent in HIV-infected persons even after the widespread implementation of highly active anti-retroviral therapy.
