[PMID: 39238507 PMCID: PMC11375285 DOI: 10.1002/ccr3.9407] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2024] [Revised: 07/04/2024] [Accepted: 07/13/2024] [Indexed: 09/07/2024] Open
Abstract
The diagnosis of extensive pulmonary tuberculosis, especially in young people, should take into account the possibility of an associated systemic autoimmune disease. Infections remain an important cause of morbidity and mortalityin systemic lupus erythematosus. This case illustrates the importance of recognizing the association of systemic autoimmune diseases and infections and the need for a multidisciplinary approach.

Abstract
Understanding the role of B cells in tuberculosis (TB) is crucial for developing new TB vaccines. However, the changes in B cell immune landscapes during TB and their functional implications remain incompletely explored. Using high-dimensional flow cytometry to map the immune landscape in response to Mycobacterium tuberculosis (Mtb) infection, our results show an accumulation of marginal zone B (MZB) cells and other unconventional B cell subsets in the lungs and spleen, shaping an unconventional B cell landscape. These MZB cells exhibit activated and memory-like phenotypes, distinguishing their functional profiles from those of conventional B cells. Notably, functional studies show that MZB cells produce multiple cytokines and contribute to systemic protection against TB by shaping cytokine patterns and cell-mediated immunity. These changes in the immune landscape are reversible upon successful TB chemotherapy. Our study suggests that, beyond antibody production, targeting the regulatory function of B cells may be a valuable strategy for TB vaccine development.

Abstract
BACKGROUND Tuberculosis (TB) is one of the most common infections among systemic lupus erythematosus (SLE) patients. We aimed to evaluate the global prevalence of TB infection and disease, its type, and medication risk factors in SLE patients. METHODS We searched PubMed, Science Direct, EBSCO, and Web of Science databases from inception to April 30, 2023, and included studies assessing TB among SLE patients. We estimated the prevalence of TB disease (including type of TB disease), TB infection, and SLE medication as TB risk factors. Meta-analysis was performed using Stata 14.2 and Review Manager 5.3. RESULTS Twenty-seven studies met the eligibility criteria. The global prevalence of TB disease was 4% (95% confidence interval (CI): 3-4%, n = 25) and TB infection was 18% (95% CI: 10-26%, n = 3). The pooled prevalence of pulmonary TB, extrapulmonary TB, and disseminated TB were 2% (95% CI: 2-3%, n = 20), 1% (95% CI: 1-2%, n = 17), and 1% (95% CI: 0-1%, n = 6), respectively. The 1-year cumulative glucocorticoid (GC) dose in SLE patients contracting TB was higher than in those without TB, having a mean difference of 2.56 (95% CI: 0.22-4.91, p < .00001, n = 3). The odd ratio of TB was 2.11 (95% CI: 1.01-4.41, p = .05, n = 3) in SLE patients receiving methylprednisolone (MP) pulse therapy as compared to those without MP pulse therapy. Other immunosuppressive agents were not significantly associated with TB. CONCLUSION TB prevalence in SLE was relatively high and associated with GC. Awareness of TB and lowering GC dose are warranted to alleviate the TB burden in SLE.

Abstract
BACKGROUND Some medical conditions may increase the risk of developing pulmonary tuberculosis (PTB); however, no systematic study on PTB-associated comorbidities and comorbidity clusters has been undertaken. METHODS A nested case-control study was conducted from 2013 to 2017 using multi-source big data. We defined cases as patients with incident PTB, and we matched each case with four event-free controls using propensity score matching (PSM). Comorbidities diagnosed prior to PTB were defined with the International Classification of Diseases-10 (ICD-10). The longitudinal relationships between multimorbidity burden and PTB were analyzed using a generalized estimating equation. The associations between PTB and 30 comorbidities were examined using conditional logistic regression, and the comorbidity clusters were identified using network analysis. RESULTS A total of 4265 cases and 17,060 controls were enrolled during the study period. A total of 849 (19.91%) cases and 1141 (6.69%) controls were multimorbid before the index date. Having 1, 2, and ≥ 3 comorbidities was associated with an increased risk of PTB (aOR 2.85-5.16). Fourteen out of thirty comorbidities were significantly associated with PTB (aOR 1.28-7.27), and the associations differed by sex and age. Network analysis identified three major clusters, mainly in the respiratory, circulatory, and endocrine/metabolic systems, in PTB cases. CONCLUSIONS Certain comorbidities involving multiple systems may significantly increase the risk of PTB. Enhanced awareness and surveillance of comorbidity are warranted to ensure early prevention and timely control of PTB.

Abstract
Patients with systemic lupus erythematosus (SLE) are at increased risk of tuberculosis (TB) infection due to immune dysfunction and immunosuppressive therapy. We present a case study of a 40-year-old woman with systemic lupus erythematosus (SLE). Initially, she was diagnosed with a lupus flare based on her clinical symptoms and laboratory results. However, upon further investigation, positive polymerase-chain reaction results for M. tuberculosis in the cerebrospinal fluid and lung parenchymal changes on chest computed tomography scan were indicative of TB infection. There was initial uncertainty regarding whether TB had triggered a flare-up of SLE or if TB was merely mimicking the symptoms of a SLE flare-up. However, as increasing the prednisolone dose did not have a positive effect and the patient's condition improved significantly with anti-TB treatment alone, it became clearer that the deterioration observed upon admission was primarily due to TB progression rather than an SLE flare-up. Additionally, we review the current literature on TB and SLE, including risk factors, diagnostic challenges, and treatment considerations, highlighting the importance of considering TB infection in patients with SLE who present with overlapping manifestations. Prompt diagnosis and treatment are essential for improving outcomes in these patients.

Abstract
Infections remain one of the leading causes of death in systemic lupus erythematosus (SLE), despite awareness of factors contributing to increased susceptibility to infectious diseases in SLE. Clinicians report challenges and barriers when encountering infection in SLE as certain infections may mimic a lupus flare. There are no evidence-based practice guidelines in the management of fever in SLE, with suboptimal implementations of evidence-based benefits related to infectious disease control and/or prevention strategies in SLE. Vigilance in identifying an opportunistic infection must be stressed when confronted by a diagnostic challenge during a presentation with a febrile illness in SLE. A balanced approach must focus on management of infections in SLE, and reduction in the glucocorticoids dose, given the need to control lupus disease activity to avoid lupus related organ damage and mortality. Clinical judgement and application of biomarkers of lupus flares could reduce false positives and overdiagnosis and improve differentiation of infections from lupus flares. Further precision-based risk and screening measures must identify individuals who would benefit most from low dose immunosuppressive therapy, targeted immune therapy, and vaccination programs.

Abstract
Objective To explore the clinical characteristics and risk factors of common systemic rheumatism concomitant with tuberculosis (TB). Methods A total of 3,906 patients of RA, SLE, and SS diagnosed in the People's Hospital of Sichuan Province from January 2007 to January 2017 were collected. One hundred and five patients with TB were included as TB group, including 42 RA, 41 SLE, and 22 SS patients. In the non-TB group, 84 RA, 82 SLE, and 44 SS patients were randomly selected during the same period. Results Fever was the most common symptom among RA, SLE, and SS patients with TB, accounting for 83.3%, 92.7%, and 68.2%, respectively. Cough, weight loss or fatigue were the next common. RA patients with TB were mostly pulmonary TB (PTB), accounting for 64.3%. The proportion of PTB for SLE and SS were 46.3%, 59.01%, respectively. In TB group, 59% RA, 57% SLE, and 62% SS with PTB had two or more chest CT findings. There were 48 TB cases received both Interferon Gamma Release Assay (IGRA) and Tuberculin skin test (TST) with positive rates of 91.8%, 45.8%, respectively. The daily average dose of glucocorticoids within 1 year in TB group was higher than that in non-TB group of SLE patients, lower counts of CD4+ T cell count were found in TB group (P < 0.05), while no such differences were found in RA and SS patients. Conclusion RA patients with TB are mainly pulmonary TB. For SLE and SS patients, the chance of PTB and extrapulmonary tuberculosis is similar. Daily average dose of glucocorticoids within 1 year may be a common risk factor for RA, SLE and SS patients developing TB. Decreased CD4+ T cell count may also be a risk factor for SLE patients with TB. Symptoms of RA, SLE, SS with TB, are similar with the primary disease or other infection. It is recommended to conduct both TST and IGRA to help diagnose TB.

Abstract
Objective Infections are common in systemic lupus erythematosus (SLE), with tuberculosis (TB) being important in an endemic environment. We studied the prevalence and spectrum of TB in SLE in Durban, South Africa. Methods A medical records review of SLE patients seen over 13-year period, and the demographic data, clinical manifestations, laboratory findings, treatment and outcome were noted. Results There were 512 SLE patients and 72 (14.1%) had TB. Thirty (41.7%) had pulmonary TB (PTB) and 42 (58.3%) had extra-pulmonary TB (EPTB). The prevalence of TB among the different ethnic groups was 36/282 (12.8%) for Indian people, 29/184 (15.8%) Black African people, 7/26 (26.9%) admixed African people and none among the 18 White people. Comparison of the 72 SLE-TB patients with 72 SLE controls showed no difference in gender, age at SLE diagnosis and disease duration. The SLE-TB patients had a significant increase in the clinical and laboratory features of disease activity (arthritis, mucocutaneous lesions, renal involvement, vasculitis, low complement, raised ds-DNA antibodies), and cumulative prednisone use over the preceding 3 months.Compared to PTB, the EPTB patients were significantly younger, developed TB earlier after SLE diagnosis, and had higher disease activity. The EPTB patients also had increase in features of disease activity (renal, thrombocytopenia, ds-DNA antibodies), and increase in ever use of intravenous methylprednisolone (IV-MP) and mycophenolate mofetil (MMF). On multivariate analysis, the independent risk factors for EPTB were ever use of MMF (p = 0.003) and IV-MP (p = 0.027). Analysis of the cumulative SLE criteria showed renal involvement was an independent risk factor for EPTB. The outcome was similar in both groups. Conclusion We show an increased prevalence of TB (14.1%) and EPTB (58.3%) in SLE in an endemic area and confirm that features of disease activity and use of immunosuppressive therapy are the major risk factors. Renal involvement (as a cumulative criterion) is an independent risk factor for EPTB.

[PMID: 37205113 PMCID: PMC10185908 DOI: 10.3389/fimmu.2023.1159713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Accepted: 04/12/2023] [Indexed: 05/21/2023] Open
Abstract
Background Tuberculosis (TB) is the deadliest communicable disease in the world with the exception of the ongoing COVID-19 pandemic. Programmed cell death (PCD) patterns play key roles in the development and progression of many disease states such that they may offer value as effective biomarkers or therapeutic targets that can aid in identifying and treating TB patients. Materials and methods The Gene Expression Omnibus (GEO) was used to gather TB-related datasets after which immune cell profiles in these data were analyzed to examine the potential TB-related loss of immune homeostasis. Profiling of differentially expressed PCD-related genes was performed, after which candidate hub PCD-associated genes were selected via a machine learning approach. TB patients were then stratified into two subsets based on the expression of PCD-related genes via consensus clustering. The potential roles of these PCD-associated genes in other TB-related diseases were further examined. Results In total, 14 PCD-related differentially expressed genes (DEGs) were identified and highly expressed in TB patient samples and significantly correlated with the abundance of many immune cell types. Machine learning algorithms enabled the selection of seven hub PCD-related genes that were used to establish PCD-associated patient subgroups, followed by the validation of these subgroups in independent datasets. These findings, together with GSVA results, indicated that immune-related pathways were significantly enriched in TB patients exhibiting high levels of PCD-related gene expression, whereas metabolic pathways were significantly enriched in the other patient group. Single cell RNA-seq (scRNA-seq) further highlighted significant differences in the immune status of these different TB patient samples. Furthermore, we used CMap to predict five potential drugs for TB-related diseases. Conclusion These results highlight clear enrichment of PCD-related gene expression in TB patients and suggest that this PCD activity is closely associated with immune cell abundance. This thus indicates that PCD may play a role in TB progression through the induction or dysregulation of an immune response. These findings provide a foundation for further research aimed at clarifying the molecular drivers of TB, the selection of appropriate diagnostic biomarkers, and the design of novel therapeutic interventions aimed at treating this deadly infectious disease.

Abstract
ObjectivesTo develop EULAR recommendations for screening and prophylaxis of chronic and opportunistic infections in patients with autoimmune inflammatory rheumatic diseases (AIIRD).MethodsAn international Task Force (TF) (22 members/15 countries) formulated recommendations, supported by systematic literature review findings. Level of evidence and grade of recommendation were assigned for each recommendation. Level of agreement was provided anonymously by each TF member.ResultsFour overarching principles (OAP) and eight recommendations were developed. The OAPs highlight the need for infections to be discussed with patients and with other medical specialties, in accordance with national regulations. In addition to biologic/targeted synthetic disease-modifying antirheumatic drugs (DMARDs) for which screening for latent tuberculosis (TB) should be performed, screening could be considered also before conventional synthetic DMARDs, glucocorticoids and immunosuppressants. Interferon gamma release assay should be preferred over tuberculin skin test, where available. Hepatitis B (HBV) antiviral treatment should be guided by HBV status defined prior to starting antirheumatic drugs. All patients positive for hepatitis-C-RNA should be referred for antiviral treatment. Also, patients who are non-immune to varicella zoster virus should be informed about the availability of postexposure prophylaxis should they have contact with this pathogen. Prophylaxis againstPneumocystis jiroveciiseems to be beneficial in patients treated with daily doses >15–30 mg of prednisolone or equivalent for >2–4 weeks.ConclusionsThese recommendations provide guidance on the screening and prevention of chronic and opportunistic infections. Their adoption in clinical practice is recommended to standardise and optimise care to reduce the burden of opportunistic infections in people living with AIIRD.

Abstract
BackgroundT-SPOT.TB (T-SPOT) is widely used for the detection of Mycobacterium tuberculosis infection by detecting interferon-gamma (IFN-γ) release in T lymphocytes. This assay is performed on peripheral blood mononuclear cells (PBMCs) separated by Ficoll density gradient centrifugation, which often contain some residual platelets. Here, we investigated the impact of platelets on T-SPOT assay and related mechanisms.MethodsThe correlation between platelet count, platelet-to-lymphocyte ratio (PLR), and the IFN-γ secreting T cells (ISCs) in positive control wells of T-SPOT assay were retrospectively analyzed. T-SPOT assay was performed with un-treated PBMCs, platelets-removed PBMCs, and platelets-enriched PBMCs to confirm the impact of platelets on T-SPOT assay. The activation of platelets and their impact on IFN-γ production in T cells were detected by flow cytometry (FCM). Platelets and T cells were cultured in a mixed culture system and co-culture system respectively, followed by detection of the frequencies of IFN-γ-producing T cells and the levels of intracellular IFN-γ in T cells by FCM. Moreover, the effect of platelet releasate on the T-SPOT assay was evaluated.ResultsThe ISCs in positive control wells of the T-SPOT assay showed a significant decrease with the increase in platelet count. The PLR of the peripheral blood were negatively correlated with the ISCs in positive control wells of the T-SPOT assay. Removal or enrichment of platelets significantly increased or decreased the ISCs and the positive rate of T-SPOT. Inhibition of platelet activation significantly increased the ISCs of T-SPOT. The frequencies of IFN-γ-producing T cells in PBMCs and the levels of intracellular IFN-γ were significantly reduced by the addition of platelets, both in the mixed culture system and the co-culture system. Platelet releasate upon thrombin activation significantly decreased the ISCs of T-SPOT.ConclusionsPlatelets correlate with negative T-SPOT results by inhibiting IFN-γ production in T cells via degranulation.

Abstract
Background Systemic lupus erythematosus (SLE) patients are particularly susceptible to infections, such as pulmonary tuberculosis (PTB) and extrapulmonary tuberculosis (EPTB). This meta-analysis aimed to determine the incidence and prevalence of tuberculosis (TB) in SLE patients. Methods The Web of Science, PubMed, Cochrane Library, and Chinese National Knowledge Infrastructure databases were searched for articles of relevant studies published from the dates the databases were established until April 30, 2022. The I2 statistic and Q test were used to evaluate heterogeneity among the analysed studies. Random-effects models were utilised and subgroup analyses were conducted for analysis of the study data. Results A total of 35 studies with 46,327 SLE patients were eligible for analysis. The incidence and prevalence of TB among the SLE patients were 1.16 per 100 person-years (95% confidence interval (CI): 0.69-1.93) and 3.59% (95% CI: 2.57%-5.02%), respectively. The pooled prevalence of SLE-PTB and SLE-EPTB was 2.46% (95% CI: 1.73%-3.51%) and 1.42% (95% CI: 0.98%-2.06%), respectively. Subgroup analyses showed that the incidence of SLE-TB was higher in Africa and in countries with a high TB burden than in countries with a low TB burden. The prevalence of SLE-TB was elevated in Asia, in patients taking a mean daily dose of glucocorticoids ≥20 mg, in studies with small sample sizes (n <1000) and ended before 2001. Conclusions The available evidence suggests that both the incidence and prevalence of TB in SLE patients are high. This study provides a more specific understanding of SLE-TB, which can help health policymakers in the development of preventive strategies for reducing the SLE-TB burden.

Abstract
Systemic lupus erythematosus (SLE) is a complex, chronic autoimmune disease, whose etiology includes both genetic and environmental factors. Individual genetic risk factors likely only account for about one-third of observed heritability among individuals with a family history of SLE. A large portion of the remaining risk may be attributable to environmental exposures and gene-environment interactions. This review focuses on SLE risk associated with environmental factors, ranging from chemical and physical environmental exposures to lifestyle behaviors, with the weight of evidence supporting positive associations between SLE and occupational exposure to crystalline silica, current smoking, and exogenous estrogens (e.g., oral contraceptives and postmenopausal hormones). Other risk factors may include lifestyle behaviors (e.g., dietary intake and sleep) and other exposures (e.g., ultraviolet [UV] radiation, air pollution, solvents, pesticides, vaccines and medications, and infections). Alcohol use may be associated with decreased SLE risk. We also describe the more limited body of knowledge on gene-environment interactions and SLE risk, including IL-10, ESR1, IL-33, ITGAM, and NAT2 and observed interactions with smoking, UV exposure, and alcohol. Understanding genetic and environmental risk factors for SLE, and how they may interact, can help to elucidate SLE pathogenesis and its clinical heterogeneity. Ultimately, this knowledge may facilitate the development of preventive interventions that address modifiable risk factors in susceptible individuals and vulnerable populations.

Abstract
Background and Purpose An increasing number of autoimmune encephalitis (AE)-associated autoantibodies have been successfully characterized. However, many cases of AE remain unexplained on account of unknown antibodies. The aim of the present study was to identify a novel antibody against collapsin response mediator protein 2 (CRMP2) in suspected AE patients. Methods A patient's serum and cerebrospinal fluid samples tested negative for known AE antibodies; however, strong immunolabel signals were observed in the neuronal cytoplasm of the cortex, hippocampus, and Purkinje cells on rat brain sections. Immunoprecipitation from the rat brain protein lysate, followed by mass spectrometry analysis, was used to identify the targeting antigen. Western blotting and cell-based assay with antigen-overexpressing HEK293T cells were used for antibody specificity, epitope, IgG subtype determination, and retrospective study. Results An antibody against CRMP2, a synaptic protein involved in axon guidance, was identified. The immunostains of the patient's samples on rat brain sections were eliminated by pre-absorption with HEK293T cells overexpressing CRMP2. The samples specifically immunoreacted with CRMP2, but not with CRMP1, CRMP3, CRMP4, and CRMP5. The C-terminus of CRMP2 with 536 amino acids contained the epitope for antibody binding. The subtype analysis showed that the anti-CRMP2 antibody was IgG4. Furthermore, a screening of 46 patients with neurological disoders and neuro-cytoplasm immunostainings on rat brain sections resulted in the identification of anti-CRMP2 antibodies in a case of encephalomyelitis. The two patients responded well to immunotherapies. Conclusions This study discovered that a novel anti-CRMP2 antibody was associated with suspected AE and thus should be included in the testing list for AE.

Abstract
BACKGROUND Hemophagocytic lymphohistiocytosis (HLH) is a rare disorder with rapid progression and high mortality. HLH occurs mostly due to infection, malignant tumors, and immune disorders. Among infections that cause HLH, viral infections, especially Epstein-Barr virus infections, are common, whereas tuberculosis is rare. Tuberculosis-associated HLH has a wide range of serological and clinical manifestations that are similar to those of systemic lupus erythematosus (SLE).
CASE SUMMARY This study describes a case of tuberculosis-associated HLH misdiagnosed as SLE because of antinuclear antibody (ANA), Smith (Sm) antibody and lupus anticoagulant positivity; leukopenia; thrombocytopenia; pleural effusion; decreased C3, quantitatively increased 24 h urinary protein and fever. The patient was initially treated with glucocorticoids, which resulted in peripheral blood cytopenia and symptom recurrence. Then, caseating granulomas and hemophagocytosis were observed in her bone marrow. She was successfully treated with conventional category 1 antituberculous drugs. In addition, we reviewed the literature on tuberculosis-associated HLH documented in PubMed, including all full-text articles published in English from December 2009 to December 2019, and summarized the key points, including the epidemiology, clinical manifestations, diagnosis, and treatment of tuberculosis-associated HLH and the differences of the present case from previous reports.
CONCLUSION Tuberculosis should be considered in patients with fever or respiratory symptoms. Antituberculous drugs are important for treating tuberculosis-associated HLH.

Abstract
We aimed to conduct a systematic review and meta-analysis of studies on central nervous system (CNS) infections in patients with SLE, in order to describe their clinical and microbiological characteristics, and outcomes. A systematic search of PubMed/Medline and Embase electronic databases was performed (March 2021) to identify all published studies on CNS infections and their characteristics in patients with SLE. A random-effects model was adopted and findings were reported with 95% CI. Overall, 6 studies involving 17 751 patients with SLE and 209 SLE cases with CNS infection were included in our meta-analysis. The frequency rate of CNS infections in patients with SLE was 0.012 (95% CI: 0.008 to 0.018). Meningitis was the most common clinical syndrome (93.5%, n=109/114, 95% CI: 82.6% to 97.8%) and Cryptococcus neoformans (35.9%, n=55, 95% CI: 27.2% to 45.7%) and Mycobacterium tuberculosis (27.1%, n=43, 95% CI: 14.6% to 44.8%) were the most common causative pathogens. Our patient-pool showed a mean SLE Disease Activity Index (SLEDAI) score of 7.9 (95% CI: 6.1 to 9.6), while 92.4% (n=72/76, 95% CI: 83.0% to 96.8%) of cases were on oral systemic corticosteroids, with a prednisone equivalent mean daily dose of 30.9 mg/day (95% CI: 18.0 to 43.7). Our meta-analysis revealed a mortality rate of 29.0% (95% CI: 15.0% to 48.6%). Clinicians should maintain a high index of suspicion for cryptococcal and tuberculosis (TB) meningitis in patients with SLE with suspected CNS infection, particularly in those with higher SLEDAI and on higher doses of systemic corticosteroids. In conclusion, initiation of empiric antituberculous treatment for patients with SLE who are highly suspected to have CNS TB is warranted while awaiting the results of diagnostic tests. Antifungals might also be potentially useful empirically in patients with SLE who are suspected to have fungal CNS infections. However, with respect to side effects such as toxicity and high cost of antifungals, decision regarding early antifungal therapy should be guided by early and less time-consuming fungal diagnostic tests.

Abstract
Objective We investigated the correlation between nontyphoidal Salmonella (NTS) infection and systemic lupus erythematosus (SLE) risk. Methods This case-control study comprised 6,517 patients with newly diagnosed SLE between 2006 and 2013. Patients without SLE were randomly selected as the control group and were matched at a case-control ratio of 1:20 by age, sex, and index year. All study individuals were traced from the index date back to their NTS exposure, other relevant covariates, or to the beginning of year 2000. Conditional logistic regression analysis was used to analyze the risk of SLE with adjusted odds ratios (aORs) and 95% confidence intervals (CIs) between the NTS and control groups. Results The mean age was 37.8 years in the case and control groups. Females accounted for 85.5%. The aOR of having NTS infection were significantly increased in SLE relative to controls (aOR, 9.20; 95% CI, 4.51-18.78) in 1:20 sex-age matching analysis and (aOR, 7.47; 95% CI=2.08-26.82) in propensity score matching analysis. Subgroup analysis indicated that the SLE risk was high among those who dwelled in rural areas; had rheumatoid arthritis, multiple sclerosis, or Sjogren’s syndrome; and developed intensive and severe NTS infection during admission. Conclusions Exposure to NTS infection is associated with the development of subsequent SLE in Taiwanese individuals. Severe NTS infection and other autoimmune diseases such as rheumatoid arthritis, multiple sclerosis, or Sjogren’s syndrome also contributed to the risk of developing SLE.

Abstract
Patients with Systemic Lupus Erythematosus (SLE) are susceptible to infection due to defects in their immune system. Corticosteroids and immunosuppressant drugs used as SLE therapy also contribute to infection. This study aimed is to determine predictors of infection in pediatric patients with SLE. This retrospective cohort study was conducted at Dr. Sardjito Hospital, a referral hospital in Yogyakarta, Indonesia between 2013 and 2019. Logistic regression analysis was performed to identify predictor variables for the occurrence of infection. A total of 109 SLE patients were included in this study. The incidence of infection in children with SLE was 27.5%. The most common types of infection in hospitalized SLE patients were urinary tract infections (41%), skin and soft tissue infections (20.5%), and pneumonia (20.5%). Multivariate regression analysis showed that the use of methylprednisolone pulse dose (RR 3.204; 95% CI 1.234-8.318) was a predictor of infection. Clinician should closely observe SLE patients with predictors for infection.

Abstract
Background T-SPOT TB (T-SPOT) assay is widely used for detection of Mycobacterium tuberculosis infection that is based on the detection of M. tuberculosis-specific interferon-γ-secreting T cells (ISCs) in peripheral blood mononuclear cells (PBMCs). Recently, high frequencies of low-density granulocytes (LDGs) were found in the PBMCs of tuberculosis patients. Whether these LDGs affect the detection of T-SPOT has not been investigated. The impact of LDGs on T-SPOT assay and related mechanism were investigated in this study. Methods The correlations between the frequencies of LDGs and the results of T-SPOT were analyzed. T-SPOT with LDG-removed PBMCs and PBMCs with exogenous addition of LDGs were performed. The possible mechanism was explored by detecting the levels of negative immune regulatory molecules on LDGs. The impact of programmed death ligand 1 (PD-L1) on T-SPOT was evaluated and confirmed by function blocking with neutralizing antibody. Results The positive rates of T-SPOT and ISCs in tuberculosis patients with low LDGs frequency (n = 22) were significantly higher than those with high LDGs frequency (n = 39). Removal or exogenous addition of LDGs significantly increased or decreased the ISCs and the positive rate of T-SPOT. The frequencies of interferon-γ-producing T cells were negatively correlated with the frequencies of LDGs. The expression of PD-L1 was significantly elevated on LDGs. Pretreatment of LDGs with anti-PD-L1 antibody significantly counteracted the impact of LDGs on T-SPOT. Treatment of PBMCs with anti-PD-L1 antibody resulted in comparable ISCs with that of LDG removal. Conclusion LDGs can inhibit the production of interferon-γ in T cells and decrease the positive rated of T-SPOT assay via highly expressed PD-L1.

Abstract
Tuberculosis is an airborne multisystemic disease which primarily infects the lungs. Isolated tuberculous arthritis is rare. We present a case of a 41-year-old woman with a known case of lupus nephritis class IV who complained of pain and swelling over her left ankle joint for several months. She was treated for rheumatoid arthritis and was started with immunosuppressive agents. However, she did not improve with treatment and was later diagnosed with tuberculous arthritis based on a molecular study from joint aspiration. She was started on antituberculosis medication and showed improvement. We highlight the challenges in reaching the diagnosis and the importance of including tuberculous arthritis in differential diagnoses in cases with persistent ankle swelling.

Abstract
PURPOSE Highly active systemic lupus erythematosus (SLE) causes a high risk of tuberculosis (TB) infection in SLE patients in Indonesia, a country in which the disease, especially extrapulmonary TB, is endemic. Interferon (IFN)-γ releasing assay (IGRA) can detect latent or previous TB infection. This study sought to determine latent TB infection and levels of IFN-γ, a key player in various inflammation and autoimmune disease, in patients with SLE and relate findings to disease activity. PATIENTS AND METHODS This experimental study included 79 female subjects distributed into three groups of active SLE, quiescent SLE and healthy controls. We used SLE Disease Activity Index-2000 (SLEDAI-2K) scores to stratify the subjects. Each group underwent IGRA testing using the QuantiFERON-TB Gold Plus kit. RESULTS We recruited 59 female patients with SLE. The patients had a median age and disease duration 30 and 5 years, respectively. Statistical analysis using the Kruskal-Wallis test showed that active condition, high SLEDAI-2K score and immunosuppressive therapies affect IGRA results. Specifically, healthy controls (n=20) were most likely to have negative IGRA results (67.09%), whilst 27.27% of active cases (n=33) and 3.85% of quiescent cases (n=26) had indeterminate results (p=0.02). The number of immunosuppressant therapies was significantly negatively correlated with IFN-γ (p=0.004). No difference in IFN-γ concentration was detected amongst the active and other groups (p>0.05). CONCLUSION High-activity SLE and immunosuppressive therapies cause dysregulation of the immune response, which, in turn, influences IGRA results. Thus, additional testing is necessary to detect TB infection in patients with SLE.

Abstract
OBJECTIVE To identify factors associated with active tuberculosis (TB) in patients with systemic lupus erythematosus (SLE). METHODS We performed a retrospective case-control study in two tertiary care teaching hospitals in Medellín, Colombia. From January 2007 to December 2017, a total of 268 patients with SLE were included. SLE patients with TB (cases) were matched 1:3 with SLE patients without TB (controls) by disease duration and the date of the hospitalization in which the diagnosis of TB was made (index date of cases) to the nearest available rheumatology hospitalization in the matched controls (± 2 years). Conditional univariable and multivariable logistic regression analyses were performed. RESULTS Sixty-seven cases and 201 controls were assessed. Only pulmonary TB occurred in 46.3%, only extrapulmonary TB in 16.4% and disseminated TB in 37.3% of cases. Multivariable logistic regression analysis showed that lymphopenia (OR, 2.91; 95% CI 1.41-6.03; P = 0.004), 12-month cumulative glucocorticoid dose ≥ 1830 mg (OR, 2.74; 95% CI 1.26-5.98; P = 0.011), and having been treated with ≥ 2 immunosuppressants during the last 12 months (OR, 2.81; 95% CI 1.16-6.82; P = 0.022) were associated with TB after adjusting for age, sex, ethnicity, disease duration, disease activity, and comorbidity index. A trend towards an association of kidney transplantation with TB was also found (OR, 3.77; 95% CI 0.99-14.30; P = 0.051). CONCLUSION Among SLE patients, cumulative glucocorticoid dose, lymphopenia, and the use of ≥ 2 immunosuppressants during the last 12 months were associated with active TB infection. Key Points • Among SLE patients, a cumulative dose of glucocorticoids equivalent to 5 mg/day of prednisone during the last 12 months is independently associated with the development of TB. • The use of two or more immunosuppressants during the last 12 months is also a risk factor for TB infection development is SLE patients. • Lymphopenia is predominant in SLE patients with TB, being especially profound in those with disseminated TB. • Renal transplant recipients with SLE also have an elevated risk of TB.

Abstract
INTRODUCTION Systemic lupus erythematosus (SLE) is an autoimmune disorder that affects almost every organ system and it is treated with immunomodulation and immunosuppression. SLE patients have an intrinsically dysfunctional immune system which is exacerbated by disease activity and leaves them vulnerable to infection. Treatment with immunosuppression increases susceptibility to infection, while hydroxychloroquine use decreases this risk. Infectious diseases are a leading cause of hospitalization and death. AREAS COVERED This narrative review provides an overview of recent epidemiology and predictors of infections in SLE, delineates the risk of infection by therapeutic agent, and provides suggestions for risk mitigation. Articles were selected from Pubmed searches conducted between September 2019 and January 2020. EXPERT OPINION Despite the large burden of infection, effective and safe preventative care such as universal hydroxychloroquine use and vaccination are underutilized. Future efforts should be directed to quality improvement, glucocorticoid reduction, and validation of risk indices that identify patients at the highest risk of infection.

Abstract
Patients with systemic lupus erythematosus (SLE) are at high risk of tuberculosis (TB) because of their immunocompromised status and the use of immunosuppressive drugs. In endemic regions, TB complicates the diagnosis and treatment of SLE, but the risk factors of mortality in these patients have not been investigated. In this study, we reviewed medical records during 2006–2016. Patients who fulfilled the 1997 American College of Rheumatology SLE criteria and presented with definite TB were enrolled. The primary outcome was mortality during TB treatment. There were 5388 SLE patients screened, and 30 patients were enrolled. Seven patients died during follow-up. Compared with the survival group, patients in the mortality group had significantly more central nervous system involvement of TB, higher Systemic Lupus Erythematosus Disease Activity Index-2000 scores and more cyclophosphamide use before TB, and higher prednisolone dose before and during TB treatment. Cox regression showed that prednisolone dose during TB treatment was an independent risk factor for mortality (per 10 mg/day increase, hazard ratio (HR) 1.61, p = .019). For SLE patients, prednisolone dose during TB treatment is an independent risk factor for mortality. Keeping prednisolone dose at less than 25 mg per day during TB treatment might be a reasonable strategy in these patients.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune chronic inflammatory disease of unknown etiology, although genetic and environmental factors appear to contribute to its pathogenesis. Specifically, infectious processes are associated with SLE onset and exacerbation. However, we are far from a complete understanding of the interactions between infectious agents and the host, explaining the interest in gathering updated scientific information on this topic. According to the literature, the pathogens most frequently associated with SLE are viruses, notably human endogenous retroviruses, Epstein-Barr virus, parvovirus B19, cytomegalovirus and human immunodeficiency virus type 1, alongside certain bacterial components that can also trigger activation of the immune system. The mechanisms underlying autoreactivity remain unclear but various explanations have been proposed, including immunological changes responsible for infectious processes or molecular mimicry between host structures and those of infectious agents.

Abstract
The leading cause of death in systemic lupus erythematosus (SLE) patients is infection. The objective of this study was to evaluate the distribution of lymphocyte subsets in untreated SLE patients with infections. This was a cross-sectional study. Data from January 2017 to May 2018 were collected. Flow cytometry was used to measure the peripheral lymphocyte subsets including CD3+T cells, CD4+T cells, CD8+T cells, CD19+B cells, CD3-CD16+CD56NK cells, and CD3+CD16+CD56NKT cells in 25 healthy controls and 52 treatment-naive SLE patients, among whom 13 were complicated with infections. Association between the lymphocyte subsets and infections was further analyzed. SLE patients with infections (n=13) showed a significantly higher incidence rate of fever (84.6 vs 28.2%) and serositis (84.6 vs 23.1%), increased level of erythrocyte sedimentation rate (60.5±30.1 vs 37.4±27.1 mm/h), serum C-reactive protein (CRP) (102.7±94.9 vs 9.4±14.9 mg/L), procalcitonin (PCT) (1.07±0.08 vs 0.16±0.13 μg/L), and lower blood hemoglobin (Hb) (93.0±20.5 vs 110.4±16.0 g/L) level compared with non-infection patients (n=39) (all P<0.05). In comparison with non-infectious SLE patients (387.9±261.6/μL), CD4+T cells count decreased significantly in infectious SLE patients (217.8±150.4/μL) (P<0.05), and it was negatively correlated with infection-related indicators including PCT (r=-0.573, P=0.041) and CRP (r=-0.596, P=0.032) levels. Our findings suggested that abnormalities of peripheral lymphocyte subsets were related to the immune disorder of lupus itself, regardless of immunosuppressive treatment. Monitoring lymphocyte subsets, especially CD4+T cells, may be helpful for identifying the presence of infection in SLE patients.

Abstract
OBJECTIVE The impact of pulmonary infection (PI) on mortality of patients with systemic lupus erythematosus (SLE) has been established. Nevertheless, the effect of risk factors in mortality remains controversial. The objective of this study is to determine the risk factors of short-term mortality among SLE patients with PI. METHOD The clinical data of 54 SLE patients with 59 episodes of PI who were hospitalized from January 2013 to May 2018 was retrospectively analyzed. Demographic data, clinical features, and outcomes were collected. Logistic regression analysis was carried out to determine the independent predictors of 60-day mortality during hospitalization. We used receiver operating characteristics (ROC) curves to verify the indices as mortality predictors in the study patients. RESULTS There were a total of 54 patients with 59 episodes of PI. There were 12 deaths during hospitalization. In multivariate analysis, 24-hour urinary protein (24h-PRO) (odds ratio [OR]: 2.713, 95% CI: 1.234-5.965, P = 0.013), peripheral lymphocyte count (OR: 0.066, 95% CI: 0.005-0.887, P = 0.040), and serum complement 3 level (C3) (OR: 0.097, 95% CI: 0.010-0.954, P = 0.045) were associated with mortality among our cohort of SLE patients with PI. ROC curve values were 0.818 for lymphocyte count (95% CI: 0.696-0.907, P = 0.001), 0.894 for 24h-PRO (95% CI: 0.786-0.959, P < 0.001) and 0.825 for C3 (95% CI: 0.704-0.912, P = 0.001). The cut-off value of lymphocytes, 24h-PRO and C3 were 0.53 × 109 /L, 0.92 g and 0.52 g/L, respectively. CONCLUSION The presence of albuminuria, lymphopenia and low complement C3 levels were independent prognostic predictors of short-term mortality in SLE patients with PI.
