Malignancy in systemic lupus erythematosus: relation to disease characteristics in 92 patients - a single center retrospective study. Rheumatol Int 2024; 44:1701-1713. [PMID: 38850326 PMCID: PMC11343918 DOI: 10.1007/s00296-024-05623-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Accepted: 05/25/2024] [Indexed: 06/10/2024]
Abstract
OBJECTIVE Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with a variable clinical manifestation, potentially leading to death. Importantly, patients with SLE have an increased risk of neoplastic disorders. Thus, this study aimed to comprehensively evaluate the clinical and laboratory characteristics of patients with SLE and with or without malignancy. METHODS We conducted a retrospective analysis of medical records of 932 adult Caucasian patients with SLE treated at the University Hospital in Kraków, Poland, from 2012 to 2022. We collected demographic, clinical, and laboratory characteristics, but also treatment modalities with disease outcomes. RESULTS Among 932 patients with SLE, malignancy was documented in 92 (9.87%), with 7 (7.61%) patients experiencing more than one such complication. Non-hematologic malignancies were more prevalent (n = 77, 83.7%) than hematologic malignancies (n = 15, 16.3%). Patients with SLE and malignancy had a higher mean age of SLE onset and a longer mean disease duration than patients without malignancy (p < 0.001 and p = 0.027, respectively). The former group also presented more frequently with weight loss (odds ratio [OR] = 2.62, 95% confidence interval [CI] 1.61-4.23, p < 0.001), fatigue/weakness (OR = 2.10, 95% CI 1.22-3.77, p = 0.005), and fever (OR = 1.68, 95% CI 1.06-2.69, p = 0.024). In the malignancy-associated group, we noticed a higher prevalence of some clinical manifestations, such as pulmonary hypertension (OR = 3.47, 95% CI 1.30-8.42, p = 0.007), lung involvement (OR = 2.64, 95% CI 1.35-4.92, p = 0.003) with pleural effusion (OR = 2.39, 95% CI 1.43-3.94, p < 0.001), and anemia (OR = 2.24, 95% CI 1.29-4.38, p = 0.006). Moreover, the patients with SLE and malignancy more frequently had internal comorbidities, including peripheral arterial obliterans disease (OR = 3.89, 95% CI 1.86-7.75, p < 0.001), myocardial infarction (OR = 3.08, 95% CI 1.41-6.30, p = 0.003), heart failure (OR = 2.94, 95% CI 1.30-6.17, p = 0.005), diabetes mellitus (OR = 2.15, 95% CI 1.14-3.91, p = 0.011), hypothyroidism (OR = 2.08, 95% CI 1.29-3.34, p = 0.002), arterial hypertension (OR = 1.97, 95% CI 1.23-3.23, p = 0.003), and hypercholesterolemia (OR = 1.87, 95% CI 1.18-3.00, p = 0.006). Patients with SLE and malignancy were treated more often with aggressive immunosuppressive therapies, including cyclophosphamide (OR = 2.07, 95% CI 1.30-3.28, p = 0.002), however median cumulative cyclophosphamide dose in malignancy-associated SLE subgroup was 0 g (0-2 g). Interestingly, over a median follow-up period of 14 years (ranges: 8-22 years) a total of 47 patients with SLE died, with 16 cases (5.28%) in the malignancy-associated SLE group and 31 cases (5.73%) in the non-malignancy SLE group (p = 0.76). The most common causes of death were infections (21.28%) and SLE exacerbation (8.51%). CONCLUSION The study highlights the relatively frequent presence of malignancies in patients with SLE, a phenomenon that demands oncological vigilance, especially in patients with a severe clinical course and comorbidities, to improve long-term outcomes in these patients.

Abstract
OBJECTIVE This study aims to investigate the influence of various clinical and immunological factors, including disease manifestations, autoantibody profile, age, gender, disease duration, and family history of systemic lupus erythematosus (SLE), on patient survival outcomes. METHODS A comparative analysis was conducted between survivors and non-survivors of SLE. Stepwise logistic regression analysis was employed to evaluate the impact of each variable on mortality, allowing for a nuanced understanding of their respective contributions. RESULTS A total of 229 patients were included in the study (187 survivors and 42 non-survivors). The median age at disease onset for survivors and non-survivors was 29 and 27.5 years respectively. A higher proportion of men was observed among non-survivors compared to survivors. Subgroup analysis revealed a significant difference in mortality rates between individuals under 22 years and those 22 years or older, with 23.5% and 7.8% mortality rates, respectively (P = 0.042). Moreover, specific clinical factors were found to be associated with increased mortality, including pulmonary arterial hypertension (PAH), anemia, thrombocytopenia, pulmonary disease, and renal disease. Conversely, certain manifestations such as arthritis and alopecia were associated with a reduced risk of mortality. Of particular importance, PAH emerged as the strongest predictor of mortality (OR 37.9, P < 0.012). CONCLUSION The findings of this study underscore the complex interplay between clinical and immunological factors in influencing survival outcomes in SLE patients. Specifically, the identification of PAH as a key predictor of mortality highlights the importance of comprehensive monitoring, early detection, and timely intervention strategies in the management of SLE patients to improve long-term prognosis.

Cellular spermine targets JAK signaling to restrain cytokine-mediated autoimmunity. Immunity 2024; 57:1796-1811.e8.

Abstract
Prolonged activation of the type I interferon (IFN-I) pathway leads to autoimmune diseases such as systemic lupus erythematosus (SLE). Metabolic regulation of cytokine signaling is critical for cellular homeostasis. Through metabolomics analyses of IFN-β-activated macrophages and an IFN-stimulated-response-element reporter screening, we identified spermine as a metabolite brake for Janus kinase (JAK) signaling. Spermine directly bound to the FERM and SH2 domains of JAK1 to impair JAK1-cytokine receptor interaction, thus broadly suppressing JAK1 phosphorylation triggered by cytokines IFN-I, IFN-II, interleukin (IL)-2, and IL-6. Peripheral blood mononuclear cells (PBMCs) from individuals with SLE showing decreased spermine concentrations exhibited enhanced IFN-I and lupus gene signatures. Spermine treatment attenuated autoimmune pathogenesis in SLE and psoriasis mice and reduced IFN-I signaling in monocytes from individuals with SLE. We synthesized a spermine derivative (spermine derivative 1 [SD1]) and showed that it had a potent immunosuppressive function. Our findings reveal spermine as a metabolic checkpoint for cellular homeostasis and a potential immunosuppressive molecule for controlling autoimmune disease.

Abstract
Antiphospholipid syndrome is an immunopathologic disorder that should be considered in all patients with recurrent and/or unexplained thromboembolic events. Antiphospholipid antibodies are diagnostic markers, and anticoagulation therapy is the therapeutic and preventive strategy. Long-term anticoagulation therapy is necessary, with careful attention to potential bleeding complications.

Abstract
Background: Lupus nephritis (LN) is an inflammation of the kidneys that is related to systemic lupus erythematosus (SLE). This study aimed to evaluate the differences in clinical and laboratory characteristics between LN and non-LN SLE patients. Methods: We conducted a retrospective analysis of medical records collected from SLE patients treated at the University Hospital in Kraków, Poland, from 2012 to 2022. All patients met the 2019 European League Against Rheumatism and the American College of Rheumatology (EULAR/ACR) criteria for SLE. Results: Among 921 SLE patients, LN was documented in 331 (35.94%). LN patients were younger at SLE diagnosis (29 vs. 37 years; p < 0.001) and had a male proportion that was 2.09 times higher than the non-LN group (16.62% vs. 7.97%; p < 0.001). They were more often diagnosed with serositis and hematological or neurological involvement (p < 0.001 for all). Hypertension and hypercholesterolemia occurred more frequently in these patients (p < 0.001 for both). LN patients exhibited a higher frequency of anti-dsDNA, anti-histone, and anti-nucleosome antibodies (p < 0.001 for all). Conversely, the non-LN group had a 1.24-fold (95% CI: 1.03-1.50; p = 0.021) increase in the odds ratio of having positive anti-cardiolipin IgM antibody results. LN patients were more frequently treated with immunosuppressants. The risk factors for experiencing at least three LN flares included female sex, younger age at the onset of LN or SLE, LN occurring later than SLE onset, the presence of anti-nucleosome or anti-dsDNA antibodies, and certain SLE manifestations such as myalgia, arthritis, proteinuria > 3.5 g/day, and pathological urinary casts in the urine sediment. Conclusions: LN patients differ from non-LN patients in the age of SLE diagnosis, treatment modalities, and autoantibody profile and have more frequent, severe manifestations of SLE. However, we still need more prospective studies to understand the diversity of LN and its progression in SLE patients.

Abstract
OBJECTIVES A timely diagnosis is imperative for curing cancer. However, in patients with rheumatic musculoskeletal diseases (RMDs) or paraneoplastic syndromes, misleading symptoms frequently delay cancer diagnosis. As metabolic remodelling characterises both cancer and RMD, we analysed if a metabolic signature can indicate paraneoplasia (PN) or reveal concomitant cancer in patients with RMD. METHODS Metabolic alterations in the sera of rheumatoid arthritis (RA) patients with (n=56) or without (n=52) a history of invasive cancer were quantified by nuclear magnetic resonance analysis. Metabolites indicative of cancer were determined by multivariable regression analyses. Two independent RA and spondyloarthritis (SpA) cohorts with or without a history of invasive cancer were used for blinded validation. Samples from patients with active cancer or cancer treatment, pulmonary and lymphoid type cancers, paraneoplastic syndromes, non-invasive (NI) precancerous lesions and non-melanoma skin cancer and systemic lupus erythematosus and samples prior to the development of malignancy were used to test the model performance. RESULTS Based on the concentrations of acetate, creatine, glycine, formate and the lipid ratio L1/L6, a diagnostic model yielded a high sensitivity and specificity for cancer diagnosis with AUC=0.995 in the model cohort, AUC=0.940 in the blinded RA validation cohort and AUC=0.928 in the mixed RA/SpA cohort. It was equally capable of identifying cancer in patients with PN. The model was insensitive to common demographic or clinical confounders or the presence of NI malignancy like non-melanoma skin cancer. CONCLUSIONS This new set of metabolic markers reliably predicts the presence of cancer in arthritis or PN patients with high sensitivity and specificity and has the potential to facilitate a rapid and correct diagnosis of malignancy.

Integrative analysis of systemic lupus erythematosus biomarkers: Role of fecal hsa-mir-223-3p and gut microbiota in transkingdom dynamics. Mol Immunol 2024; 171:77-92.

Abstract
Systemic lupus erythematosus (SLE) involves a florid set of clinical manifestations whose autoreactive origin is characterized by an overactivation of the immune system and the production of a large number of autoantibodies. Because it is a complex pathology with an inflammatory component, its pathogenesis is not yet fully understood, assuming both genetic and environmental predisposing factors. Currently, it is known that the role of the human microbiome is crucial in maintaining the transkingdom balance between commensal microorganisms and the immune system. In the present work we study the intestinal microbiota of Argentine patients with different stages of SLE receiving or not different treatments. Microbiota composition and fecal miRNAs were assessed by 16 S sequencing and qPCR. hsa-miR-223-3p, a miRNA involved in several inflammation regulation pathways, was found underexpressed in SLE patients without immunosuppressive treatment. In terms of microbiota there were clear differences in population structure (Weighted and Unweighted Unifrac distances, p-value <0.05) and core microbiome between cases and controls. In addition, Collinsella, Bifidobacterium, Streptococcus genera and aromatics degradation metabolisms were overrepresented in the SLE group. Medical treatment was also determinant as several microbial metabolic pathways were influenced by immunosuppressive therapy. Particularly, allantoin degradation metabolism was differentially expressed in the group of patients receiving immunosuppressants. Finally, we performed a logistic regression model (LASSO: least absolute shrinkage and selection operator) considering the expression levels of the fecal hsa-miR223-3p; the core microbiota; the differentially abundant bacterial taxa and the differentially abundant metabolic pathways (p<0.05). The model predicted that SLE patients could be associated with greater relative abundance of the formaldehyde oxidation pathway (RUMP_PWY). On the contrary, the preponderance of the ketodeoxyoctonate (Kdo) biosynthesis and activation route (PWY_1269) and the genera Lachnospiraceae_UCG_004, Lachnospira, Victivallis and UCG_003 (genus belonging to the family Oscillospiraceae of the class Clostridia) were associated with a control phenotype. Overall, the present work could contribute to the development of integral diagnostic tools for the comprehensive phenotyping of patients with SLE. In this sense, studying the commensal microbial profile and possible pathobionts associated with SLE in our population proposes more effective and precise strategies to explore possible treatments based on the microbiota of SLE patients.

Abstract
BACKGROUND Lupus nephritis (LN) manifests systemic lupus erythematosus (SLE) and is characterized by various clinical and laboratory features. This study aimed to comprehensively evaluate the characteristics of LN patients according to the time of LN diagnosis: early-onset (LN diagnosed within one year from SLE diagnosis) vs. delayed-onset (LN diagnosed more than one year after SLE diagnosis). METHODS We conducted a retrospective analysis of medical records from all SLE patients treated at the University Hospital in Kraków, Poland, from 2012 to 2022. We collected data on demographic, clinical, and laboratory characteristics, including histological findings, treatment modalities, and disease outcomes. Statistical analyses were performed to identify factors impacting LN development and prognosis. RESULTS Among 331 LN patients, early-onset was diagnosed in 207 (62.54%) and delayed-onset was documented in 122 cases (36.86%). In 2 (0.6%) LN cases, the time of first kidney manifestation in the SLE course was unknown. Delayed-onset LN had a higher female-to-male ratio and younger age at SLE diagnosis. This group was associated with more severe clinical manifestations. In turn, studied subgroups did not differ in internist comorbidities, kidney histopathology, and family history regarding autoimmune diseases. Delayed-onset LN exhibited a higher frequency of anti-dsDNA, anti-Smith, anti-Ro, anti-RNP, and anti-cardiolipin IgG autoantibodies. During a 14-year follow-up period, 16 patients died. Mortality rate and causes of death were comparable in both analyzed subgroups. CONCLUSIONS More severe clinical manifestations in delayed-onset LN prompt strict monitoring of non-LN SLE patients to diagnose and treat kidney involvement early. Also, recognizing the higher frequency of autoantibodies such as anti-dsDNA or anti-Smith in delayed-onset LN underscores the potential value of autoantibody profiling as a diagnostic and prognostic tool.

Abstract
BACKGROUND Thrombotic microangiopathy (TMA) is an important risk factor for the prognosis of lupus nephritis (LN). Patients with LN complicated with TMA tend to be critically ill with high mortality and poor prognosis. In the present study, we retrospectively analyzed the clinical manifestations, laboratory results, renal pathological manifestations, and prognosis of children with LN-TMA and analyzed the risk factors for end-stage renal disease (ESRD) in children with LN-TMA. METHODS Seventy-four patients with LN and renal TMA (rTMA) were selected and compared to 128 LN controls without TMA (1:2 ratio) matched according to demographics, pathological type and treatments. RESULTS The mean values of systolic blood pressure, diastolic blood pressure (DBP), lactate dehydrogenase (LDH), blood urea nitrogen (BUN), urinary protein quantitation (PRO), urine red blood cells, N-acetyl-β-D-glucosidase (NAG), retinol-binding protein, systemic lupus erythematosus disease activity score (SLEDAI), and activity index (AI) scores in the TMA group were all higher than those in the non-TMA group (p < 0.05 and p < 0.01). The mean values of complement C3, hemoglobin, platelets, estimated glomerular filtration rate, and chronic index (CI) score in the TMA group were all lower than those in the non-TMA group (p < 0.05 and p < 0.01). The number of cases of glomerular crescent, fibrous crescent, endocapillary proliferation, tubular atrophy, interstitial fibrosis, C3 and C1q deposition in the TMA group was higher than that in the non-TMA group (p < 0.05 and p < 0.01). The 3-year and 5-year renal survival rates in the TMA group (88.93% vs. 97.00%, p < 0.05) and TMA group (61.41% vs. 82.31%, p < 0.05) were significantly lower than those in the non-TMA group. Multivariate Cox regression analysis showed that serum creatinine before treatment (≥110 μmol/L), TMA and interstitial fibrosis were independent risk factors for the development of ESRD in LN children. CONCLUSION The general condition of children with TMA is critical, and the prognosis is poor. Early detection, early treatment and the development of new treatments are key to improving LN-TMA outcomes in children.

Abstract
OBJECTIVE This study aimed to evaluate the prevalence of sarcopenia and its clinical significance in Turkish women with SLE, exploring the association between muscle mass, muscle strength and SLE disease activity. METHODS A cross-sectional study was conducted at Gazi University Hospital's Department of Rheumatology from January to December 2020. It involved 82 patients with SLE, diagnosed according to the 2019 American College of Rheumatology/European Alliance of Associations for Rheumatology criteria, and 69 healthy controls. Sarcopenia was assessed using hand grip dynamometry (hand grip strength (HGS)) and bioelectrical impedance analysis for muscle mass, with sarcopenia defined according to the 2018 European Working Group on Sarcopenia in Older People criteria and specific cut-offs for the Turkish population. The main outcomes measured were the presence of sarcopenia and probable sarcopenia, HGS values, skeletal muscle mass index and SLE Disease Activity Index 2000 (SLEDAI-2K). RESULTS Among the patients with SLE, 51.2% met the criteria for probable sarcopenia and 12.9% were diagnosed with sarcopenia. The mean HGS was significantly lower in the SLE group (21.7±4.9 kg) compared with controls, indicating reduced muscle strength. The prevalence of anti-double-stranded DNA (anti-dsDNA) antibodies was 82.9%. Multivariate regression analysis identified height and levels of anti-dsDNA antibodies as independent predictors for developing probable sarcopenia. No significant association was found between clinical parameters, including SLEDAI-2K scores, and sarcopenia status. CONCLUSIONS Sarcopenia is prevalent among Turkish women with SLE, with a significant proportion showing reduced muscle strength. The study found no direct association between sarcopenia and SLE disease activity or clinical parameters. These findings underscore the importance of including muscle strength assessments in the routine clinical evaluation of patients with SLE to potentially improve management and quality of life.

Abstract
Thymic tumors are very rare neoplasms in children and account for less than 1% of mediastinal tumors in pediatric patients. One-third of the pediatric patients present with symptoms related to the compression of the tumor mass on the surrounding anatomic structures, and paraneoplastic syndromes such as myasthenia gravis, pure red cell aplasia, acquired hypogammaglobulinemia, and connective tissue disorders, which rarely occur in children with thymic tumors. Herein, we report a case of thymic carcinoma mimicking the symptoms of a connective tissue disease with symmetrical polyarthritis accompanying myositis, fever, weight loss, and malaise in a 15-year-old male patient. To our knowledge, this is the first case pediatric thymic carcinoma accompany with severe polyarthritis and myopathy, thus we have reviewed the current literature regarding the cases of thymic malignancies coexisting with paraneoplastic syndromes in children.

Abstract
OBJECTIVE Irreversible organ damage is common in patients with systemic lupus erythematosus (SLE). Despite evidence of increased prevalence and severity of SLE in Asia Pacific, organ damage is less well studied in this region. This systematic review aims to identify predictors of organ damage in SLE in the Asia Pacific region. METHODS We searched Medline, PubMed, Embase, and Web of Science for observational studies on organ damage in adult patients with SLE in Asia Pacific from August 31, to September 5, 2022. Study selection and data extraction were completed by two independent reviewers using Covidence systematic review software. Risk of bias was assessed using the Newcastle-Ottawa Scale and Joanna Briggs Institute tool. Significant results from univariable and multivariable analyses were synthesized from included studies. RESULTS Thirty-eight eligible studies were selected from 1999 to 2022; 22 (58%) of these reported organ damage at study enrollment and 19 (50%) reported damage accrual, as measured by the Systemic Lupus International Collaborating Clinic/American College of Rheumatology Damage Index. Factors predictive of organ damage included older age, glucocorticoid use, longer disease duration, and disease activity. Lupus nephritis was a risk factor for renal and overall damage accrual. Hydroxychloroquine was protective against overall organ damage. CONCLUSION Predictors of organ damage in SLE in Asia Pacific are similar to other regions. Although glucocorticoid use is a modifiable risk factor for organ damage, the impact of immunosuppressives and biologic therapies needs further investigation. Effective strategies in early disease are needed to minimize initial organ damage as it predicts subsequent damage accrual.

Abstract
Sjogren's syndrome (SS) is a complex systemic autoimmune disease. This study aims to elucidate a humanized NOD-PrkdcscidIl2rgem1/Smoc (NSG) murine model to better clarify the pathogenesis of SS. NSG female mice were adoptively transferred with 10 million peripheral blood mononuclear cells (PBMCs) through the tail vein from healthy controls (HCs), primary Sjogren's syndrome (pSS), and systemic lupus erythematosus (SLE) patients on D0. The mice were subcutaneously injected with C57/B6j submandibular gland (SG) protein or phosphate-buffered saline on D3, D17 and D31, respectively. NSG mice were successfully transplanted with human PBMCs. Compared with NSG-HC group, NSG-pSS and NSG-SLE mice exhibited a large number of lymphocytes infiltration in the SG, decreased salivary flow rate, lung involvement, decreased expression of genes related to salivary secretion, and the production of autoantibodies. Type I interferon-related genes were increased in the SG of NSG-pSS and NSG-SLE mice. The ratio of BAX/BCL2, BAX, cleaved caspase3, and TUNEL staining were increased in the SG of NSG-pSS and NSG-SLE mice. The expressions of p-MLKL and p-RIPK3 were increased in the SG of NSG-pSS and NSG-SLE mice. Increased expression of type I interferon-related genes, PANoptosis (apoptosis and necroptosis) were identified in the SG of this typical humanized NSG murine model of SS.

Abstract
Background Immune disorders and autoantibodies has been noted in both primary immune thrombocytopenia (ITP) and systemic lupus erythematosus (SLE). Whether the two disorders are correlated is unclear. The lack of evidence on the incidence of and risk factors for SLE in primary ITP patients poses a challenge for prediction in clinical practice. Therefore, we conducted this study. Methods The protocol was registered with PROSPERO (CRD42023403665). Web of Science, Cochrane, PubMed, and EMBASE were searched for articles published from inception to 30 September 2023 on patients who were first diagnosed with primary ITP and subsequently developed into SLE. Furthermore, the risk factors were analyzed. Study quality was estimated using the Newcastle-Ottawa Scale. The statistical process was implemented using the R language. Results This systematic review included eight articles. The incidence of SLE during the follow-up after ITP diagnosis was 2.7% (95% CI [1.3-4.4%]), with an incidence of 4.6% (95% CI [1.6-8.6%]) in females and 0 (95% CI [0.00-0.4%]) in males. Older age (OR = 6.31; 95% CI [1.11-34.91]), positive antinuclear antibody (ANA) (OR = 6.64; 95% CI [1.40-31.50]), hypocomplementemia (OR = 8.33; 95% CI [1.62-42.91]), chronic ITP (OR = 24.67; 95% CI [3.14-100.00]), organ bleeding (OR = 13.67; 95% CI [2.44-76.69]), and female (OR = 20.50; 95% CI [4.94-84.90]) were risk factors for subsequent SLE in ITP patients. Conclusion Patients with primary ITP are at higher risk of SLE. Specific follow-up and prevention strategies should be tailored especially for older females with positive ANA, hypocomplementemia, or chronic ITP. In subsequent studies, we need to further investigate the risk factors and try to construct corresponding risk prediction models to develop specific prediction strategies for SLE.

Abstract
OBJECTIVES In a cross-sectional study, we explored possible differences in sleep parameters between SLE patients and age- and gender-matched healthy controls through actigraphic and self-reported measures. Furthermore, we aimed to identify possible predictors of such disturbances in the patient cohort. METHODS Participants' sociodemographic data and sleep parameters were collected. Sleep parameters were evaluated through the Pittsburgh Sleep Quality Index, the Insomnia Severity Index and 7-day actigraphic monitoring. The 10-item Perceived Stress Scale was used to investigate stress. Disease activity and daily glucocorticoid dose were assessed in SLE patients. Possible predictors of the SLE group were explored through two binomial logistic models. Within the SLE group, possible predictors of sleep parameters were tested estimating multiple linear regression models. RESULTS A total of 40 SLE patients and 33 controls were included in the study. The SLE group showed worse sleep maintenance actigraphic parameters (i.e. sleep efficiency and wake after sleep onset), higher total sleep time and higher perceived stress. Within the SLE cohort, the daily glucocorticoids dose was associated with an impairment in sleep maintenance despite no reduction in sleep duration, typical of normal sleep duration insomnia, whereas perceived stress was associated with short sleep duration insomnia. CONCLUSION Compared with healthy controls, SLE patients showed worse sleep quality and greater perceived stress severity. As glucocorticoids and perceived stress are associated with different types of insomnia in these patients, a multidimensional approach to both sleep characterization and therapy might be preferred.

Abstract
Systemic lupus erythematosus (SLE) is a persistent autoimmune disorder that manifests across a spectrum ranging from mild to severe disease, often requiring hospitalization and critical care management. We present a severe case of systemic involvement at its onset. A young woman, with a background of arterial hypertension, presented to the emergency department exhibiting a total anterior circulation stroke and exuberant symmetric lower limb edema. Her condition rapidly deteriorated with neurological impairment, respiratory failure requiring mechanical ventilation, and acute kidney injury prompting her admission to the ICU. Following clinical investigation, a diagnosis of SLE was established, according to the European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) 2019 and Systemic Lupus International Collaborating Clinics (SLICC) 2012 classification criteria. The patient underwent treatment involving high-dose corticosteroids, followed by the Euro-Lupus protocol, resulting in significant improvement, despite her severe neurological deficit at admission. Lupus is a complex disease that is often difficult to diagnose because of its potential to mimic various other conditions. Our report delves into a case of previously undiagnosed lupus leading the patient to the ICU. The clinical scenario described adds valuable insights to the understanding of lupus-related complications and their management through a multidisciplinary approach.

Abstract
Cheilitis, or inflammation of the lips, is a common reason for dermatologic consultation. The inflammation can include the vermillion lip, vermillion border, and surrounding skin, and can present with an acute or chronic course. There are many etiologies, including irritant and allergic contact dermatitis, atopic cheilitis, actinic cheilitis, infectious etiologies, nutritional deficiencies, drug-induced cheilitis, and rare etiologies, including granulomatous cheilitis, cheilitis glandularis, plasma cell cheilitis, lupus cheilitis, and exfoliative cheilitis. Distinguishing among the various etiologies of cheilitis is clinically difficult, as many causes may produce similar erythema and superficial desquamation of mucosal skin. In addition, patients report dryness, redness, irritation, burning, fissuring, and itch in many of the underlying causes. Thus, the specific etiology of cheilitis is often difficult to diagnose, requiring extensive testing and treatment trials. In this review, we summarize the various types of cheilitis, synthesizing novel cases, clinical presentations, histopathology, epidemiology, and advancements in diagnostic methods and therapeutics. We provide a diagnostic algorithm aimed to assist clinicians in the management of cheilitis.

Identification of pattern recognition receptor genes in peripheral blood mononuclear cells and monocytes as biomarkers for the diagnosis of lupus nephritis. Clin Chim Acta 2024; 554:117785. [PMID: 38228224 DOI: 10.1016/j.cca.2024.117785] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Revised: 01/10/2024] [Accepted: 01/11/2024] [Indexed: 01/18/2024]
Abstract
BACKGROUND The study aimed to investigate the diagnostic value of lupus-related pattern recognition receptors (PRRs) genes in peripheral blood mononuclear cells (PBMCs) and monocytes (MONs) for lupus nephritis (LN). METHODS PBMCs were isolated from a cohort with 37 LN patients and 39 healthy controls (HCs), and MONs were derived from another cohort with 70 LN patients and 66 HCs. Q-PCR was used to measure the mRNA levels of CGAS, IFNB1, AIM2, IL1Β, NLRC4, NLRP3, NLRP12 and ZBP1 in the PBMCs and MONs. The Mann-Whitney U test was used to compare the data in LN patients and HCs. Eleven GEO datasets of SLE/LN were used to perform differentially expressed genes (DEGs) analysis to these PRR genes. Receiver operating characteristic (ROC) curve analysis was employed to assess the performance of individual genes or the disease prediction model established by combining multiple genes in LN diagnosis. Spearman correlation method was done to analyze the correlation between these PRRs and other clinical characteristics. RESULTS The mRNA levels of five genes (AIM2, NLRC4, IL1B, NLRP12 and ZBP1) in PBMCs, and seven genes (CGAS, IFNB1, AIM2, IL1B, NLRP3, NLRP12 and ZBP1) in MONs of LN patients were significantly higher than those of HCs (P < 0.05). DEGs analysis based on the GEO datasets showed that ZBP1, AIM2 and IL1B were significantly increased in several datasets. The ROC curve analysis indicated that the area under curve (AUC) of the LN prediction models derived from PBMCs or MONs were 0.82 or 0.91 respectively. In addition, the expression levels of these PRRs were correlated with other clinical features in LN patients, including Anti-Sm, ESR, serum Cr, and C3. CONCLUSION Our study suggests that these lupus-related PRRs might be served as potential biomarkers of LN.

Abstract
TNFAIP3 is a classical systemic lupus erythematosus (SLE)-associated risk locus identified by genome-wide association studies (GWASs) and replicated by candidate gene association studies primarily in Caucasians and Asians. However, in Latin American populations, its role on SLE susceptibility is not known. We conducted a case-control study to evaluate whether the TNFAIP3 rs2230926T/G (Phe127Cys) variant is associated with risk of developing SLE in a cohort of Mexican patients. The TNFAIP3 rs2230926T/G variant was analyzed in 561 patients with SLE and 499 control subjects, using TaqMan probes. We found that the G allele was associated with susceptibility to SLE under the allelic (OR 2.09, p = 0.005) and genotypic (OR 2.14, p = 0.004) models. In conclusion, our results show that TNFAIP3 rs2230926T/G is a risk factor for the development of SLE in the Mexican population.

Abstract
Systemic lupus erythematosus (SLE) is a complex autoimmune disease. Current SLE therapies include immunosuppressants, antimalarial drugs, non-steroidal anti-inflammatory drugs (NSAIDs), and corticosteroids, but these treatments can cause substantial toxicities to organs and may not be effective for all patients. In recent years, significant progress has been made in the treatment of SLE using immunotherapy, including Benlysta and Saphnelo. These advances in immunotherapy hold promise for SLE patients, providing new therapeutic options that may offer better clinical benefit and effectiveness. Simultaneously, several new biological therapies focusing on cytokines, peptides, targeted antibodies, and cell-based approaches are under clinical evaluation and have shown immense potential for the treatment of SLE. However, the complexity of SLE immunopathogenesis and disease heterogeneity present significant challenges in the development of effective immunological therapies. This review aims to discuss past experiences and understanding of diverse immunological targeting therapies for SLE and highlight future perspectives for the development of novel immunological therapies.

Abstract
BACKGROUND Systemic Lupus Erythematosus (SLE) is a chronic autoimmune multi-system disorder frequently affecting black women of childbearing age. No published data exist on the obstetric outcomes in a Caribbean population. OBJECTIVE We analyzed pregnancy outcomes in an Afro-Caribbean cohort of women with SLE at a tertiary university hospital. METHODS A retrospective cohort study was performed of all pregnant women with SLE prior to pregnancy from January 1990 to December 2021 at the University Hospital of the West Indies (UHWI), Jamaica. Maternal rheumatologic, obstetric, fetal/neonatal data were analyzed. Descriptive statistical analyses were performed. To determine if outcomes were associated with various factors, Spearman's rho was followed by logistic regression analysis to estimate unadjusted odds ratios with statistical significance at p < 0.05. RESULTS A total of 56 pregnancies in 47 women were identified with SLE. Live births were 87.5%, with 10.7% spontaneous miscarriages and no neonatal deaths. Prednisone was the most used drug in 67.9% of patients. 85% of women had an adverse outcome with an adverse fetal outcome occurring in 55% of cases. Prednisone was associated with an adverse fetal/neonatal outcome (Spearman's rho = 0.38; p = .004). CONCLUSION In this first Caribbean series on SLE in pregnancy, reasonably successful pregnancy outcomes are achievable in Afro-Caribbean women managed in multidisciplinary centers.

Abstract
OBJECTIVE The present study is aimed to develop and validate a quality of life scale for systemic lupus erythematosus (SLE) patients with Chinese cultural background, QLICD-SLE (V2.0). METHODS The QLICD-SLE (V2.0) was developed using a systematic approach that involved focus groups, nominal discussions, and pilot testing. A total of 428 SLE patients participated in the scale's assessment. Validity was examined through qualitative analysis, item domain correlation, multidimensional scaling, and factor analysis. Reliability was assessed using Pearson's correlation and Cronbach's alpha coefficients. To evaluate responsiveness, paired T-tests were conducted to compare pre- and post-treatment measurements with the standardised response mean (SRM) being calculated. RESULTS Correlation and factor analyses demonstrated strong construct validity. When using SF-36 as criteria, the correlation between various domains of QLICD-SLE and SF-36 ranged from 0.55 to 0.70. Test-retest correlation coefficients exceeded 0.71, and Cronbach's alpha coefficients for both measurements in each domain were greater than or equal to 0.75. T-test results showed that both the overall score and most facet scores within each domain showed statistically significant changes after treatment (P < 0.05), indicating reasonable responsiveness. CONCLUSION The QLICD-SLE (V2.0) appears to be a valid and reliable instrument for assessing the quality of life in patients with SLE.

Abstract
Background: Systemic lupus erythematosus (SLE) is a common autoimmune disease with various symptoms involving multiple organs. Neuropsychological manifestations are various and generally serious. Leukoencephalopathy is particularly rare but life-threatening in patients with SLE. Results: Here, we describe the case of a young woman who developed a subacute onset intracranial hypertension, papillar edema on fundus examination, diffuse cerebral edema on brain CT scan, and diffuse leukoencephalopathy on brain magnetic resonance imaging (MRI). The immunological workup was positive for antinuclear antibodies, anti-DNA and anti-extractable nuclear antigens (ENA) antibodies. She was ultimately diagnosed with SLE and experienced significant improvement after treatment with high dose of corticosteroids, acetazolamide, and immunosuppressant. We additionally review the previously reported cases of SLE with diffuse cerebral edema and leukoencephalopathy with a focus on the possible pathophysiological mechanisms of such association. Conclusions: We highlight, through this case report and the literature review, the importance of considering SLE in patients with cerebral edema and diffuse leukoencephalopathy and treating it aggressively.

Abstract
BACKGROUND The linkage between prolactin (PRL) and systemic lupus erythematosus (SLE) is still vague. Determination of serum levels of prolactin to reveal its role in patients with SLE is the aim of the study. METHODS This is a case-control study performed on 40 children with SLE and 40 age- and sex-matched controls. Cases were further subdivided according to disease activity into mild, moderate, and severe groups using the SLEDAI (Systemic Lupus Erythematosus Disease Activity Index) score. Serum prolactin levels were assayed by ELISA (enzyme-linked immunosorbent assay). RESULTS prolactin level was significantly higher in SLE patients (17.3 ± 6.6 µg/L) than in controls (13.5 ± 5.3 µg/L) (P value = 0.005). Although the prolactin level was highest in severe cases (19.3 ± 7.7 µg/L), followed by moderate cases (17.0 ± 5.3 µg/L), and lowest in mild cases (14.0 ± 6.2 µg/L), the variance between the 3 groups was not statistically significant (P value = 0.212). A significant positive correlation between prolactin level and SLEDAI score was detected (r = 0.368) (P value = 0.019). Hyperprolactinemia was found in 8 patients (20%) but not in controls; 4 out of 8 patients with hyperprolactinemia (50%) showed neurological manifestations compared to only 3 out of 32 patients with a normal prolactin level (9.4%) (P value = 0.007). CONCLUSION A relationship between serum prolactin levels and juvenile SLE disease was detected. Neurological manifestations were more prevalent among SLE patients with hyperprolactinemia.

Abstract
BACKGROUND The Renal Activity Index for Lupus (RAIL) consists of urine protein assessment of neutrophil gelatinase-associated lipocalin, kidney injury molecule-1, monocyte chemotactic protein 1, adiponectin, hemopexin, and ceruloplasmin, which non-invasively identifies lupus nephritis (LN). We aimed to delineate RAIL scores with inactive versus active LN and changes over time with response to LN induction therapy. METHODS There were 128 pediatric patients with systemic lupus erythematosus (SLE) and age-matched healthy controls recruited in a prospective case control study, with kidney biopsy confirmation of LN. Laboratory and clinical information was recorded and urine collected at diagnosis and end of induction and during maintenance therapy. Response to therapy was assessed by repeat kidney biopsy or laboratory parameters. Urine was assayed for RAIL biomarkers and the RAIL score calculated. RESULTS Pediatric RAIL (pRAIL) scores from 128 children and young adults with SLE (with/without LN: 70/38) including 25 during LN induction therapy, differentiated clinically active LN from inactive LN or without LN, and controls (all p < 0.0017). pRAIL scores significantly decreased with complete LN remission by 1.07 ± 1.7 (p = 0.03). CONCLUSIONS The RAIL biomarkers differentiate LN patients based on activity of kidney disease, with decreases of ≥ 1 in pRAIL scores indicating complete response to induction therapy. Significantly lower RAIL scores in healthy controls and in SLE patients without known LN raise the possibility of subclinical kidney disease. A higher resolution version of the Graphical abstract is available as Supplementary information.

OBJECTIVE To determine vitamin D levels in patients with SLE and evaluate their relationship to bone mineral density (BMD) and the disease course. METHODS The study included 101 patients with SLE and 29 individuals in the control group. The study participants were tested for vitamin D level, erythrocyte sedimentation rate (ESR), C reactive protein (CRP), interleukin (IL)-6, osteocalcin (OC) and collagen type I C-terminal telopeptide (CTX), and the dual-energy X-ray absorptiometry was provided to assess BMD in the lumbar spine and the hip. RESULTS The mean serum vitamin D level was 18.98±0.88 ng/mL, and women had 25.42% lower vitamin D levels than men (p<0.05). There was no correlation between vitamin D levels and patient's age or disease course. There was a significant inverse correlation between vitamin D levels and cumulative dose of glucocorticoids (r=-0.26) and serum inflammatory markers, particularly CRP (r=-0.39), IL-6 (r=-0.37) and ESR (r=-0.15). Vitamin D level was associated with the bone turnover markers (BTMs). In women of reproductive age with vitamin D deficiency, BMD of the lumbar spine and the hip was 9.5-23.1% higher than in those with no vitamin deficiency, respectively, and the mean lumbar spine Z-score in women of reproductive age with vitamin D insufficiency and deficiency was significantly 2.0 and 2.9 times lower than in patients with normal vitamin D level. CONCLUSIONS Hypovitaminosis D is quite common in patients with SLE and is associated with high inflammatory activity (SLE Disease Activity Index, ESR, CRP, IL-6), severity of organ damage (Damage Index), cumulative dose of glucocorticoids, BTM changes (decrease in OC, increase in CTX) and BMD decline. Vitamin D status was not associated with the patient's age or disease course.

Abstract
Background and objective Systemic autoimmune disorders involve abnormal immune responses leading to tissue damage. Dysfunction of the thyroid gland due to autoimmune mechanisms is common in such disorders, which can cause either hypofunctioning or hyperfunctioning of the gland. This study aimed to investigate the prevalence of thyroid dysfunction among patients with various systemic autoimmune disorders. Material and methods This cross-sectional observational study included 110 adult patients either diagnosed with or having clinical/biological features of systemic autoimmune diseases. The patients underwent a detailed clinical history assessment, physical examination, and necessary investigations. Data were analyzed using IBM SPSS Statistics for Windows, Version 26.0. (IBM Corp., Armonk, NY). Results Among the 110 autoimmune disorder patients, 22.7% had thyroid dysfunction, specifically hypothyroidism, while 77.3% were euthyroid. Hypothyroidism was prevalent among patients with rheumatoid arthritis (RA, 20.3%), systemic sclerosis (SSc, 20%), ankylosing spondylitis (AS, 15.8%), and systemic lupus erythematosus (SLE, 54.5%). Moreover, 60% of patients were anemic, and the prevalence of anemia was higher among female patients and younger individuals. Conclusions This study showed a higher prevalence of thyroid dysfunction, particularly hypothyroidism, in patients with systemic autoimmune disorders. Female patients and younger individuals were more susceptible to autoimmune disorders, thyroid dysfunction, and anemia. These findings highlight the need for simultaneous screening and evaluation for thyroid dysfunction and anemia in systemic autoimmune disease patients, particularly in female patients and those of younger age groups.

Abstract
BACKGROUND The clinical and serologic heterogeneity of systemic lupus erythematosus (SLE) presents challenges for diagnosis, particularly in the earliest stages of the disease when there are insufficient signs to make a reliable diagnosis. AIM To make a comparative assessment of sensitivity and specificity of various classification criteria of SLE on a cohort of patients of Nasonova Research Institute of Rheumatology. MATERIALS AND METHODS A total of 252 patients were included in the study; 152 (60%) of 252 patients had reliable SLE (mean age 36 [29.5-46] years, duration of disease 9 [3.4-19] years). Of 252 patients, 26 (11%) had PAPS (mean age 36.5 [31-42] years, duration of disease 4.6 [1-10.4] years). Systemic sclerosis was diagnosed in 74/252 (29%) patients, (mean age 51.5 [42-59] years, duration of disease 9 [5-16] years). The quality of the classification function of the criteria was assessed by ROC analysis. RESULTS SLE was diagnosed in 131 (86%) of 152 patients using the American College of Rheumatology - ACR)-1997 criteria, in 145 (95%) using the The Systemic Lupus International Collaborating Clinics (SLICC) 2012 criteria, and in 144 (94.7%) using the European League Against Rheumatism (EULAR)/ACR 2019 criteria. ANF positivity was the least statistically significant of all signs in relation to the diagnosis of SLE. The area under the curve (AUC) for ANF≥1/160 titers was AUC 0.654 for the ACR-97 criteria, AUC 0.616 for the SLICC-12 SLE criteria, and AUC 0.609 for the 2019 EULAR/ACR criteria. ROC analysis of the relationship between the number of criteria/points and a reliable diagnosis of SLE revealed a high diagnostic accuracy - the AUC for all SLE criteria was greater than 0.940. In the ROC analysis of patients with SLE and PAFS, indicating the number of diagnostic criteria, sensitivity was 86% for ACR-1997, 95% for SLICC-2012, 95% for EULAR/ACR 2019, and specificity was 100, 62 and 62%, respectively. CONCLUSION The classification criteria SLICC-2012 and EULAR/ACR 2019 are more sensitive for the diagnosis of SLE in the Russian population, and the criteria ACR-1997 are more specific. All three variants of the SLE classification criteria have sufficient sensitivity and specificity for their use in real clinical practice.

Abstract
OBJECTIVES To assess the sensitivity and specificity of the 2019 EULAR/American College of Rheumatology (ACR) classification criteria for systemic lupus erythematosus (SLE) in outpatients at an academic tertiary care centre and to compare them to the 1997 ACR and the 2012 Systemic Lupus International Collaborating Clinics criteria. METHODS Prospective and retrospective observational cohort study. RESULTS 3377 patients were included: 606 with SLE, 1015 with non-SLE autoimmune-mediated rheumatic diseases (ARD) and 1756 with non-ARD diseases (hepatocellular carcinoma, primary biliary cirrhosis, autoimmune hepatitis). The 2019 criteria were more sensitive than the 1997 criteria (87.0% vs 81.8%), but less specific (98.1% vs 99.5% in the entire cohort and 96.5% vs 98.8% in patients with non-SLE ARD), resulting in Youden Indexes for patients with SLE/non-SLE ARD of 0.835 and 0.806, respectively. The most sensitive items were history of antinuclear antibody (ANA) positivity and detection of anti-double-stranded deoxyribonucleic acid (dsDNA) antibodies. These were also the least specific items. The most specific items were class III/IV lupus nephritis and the combination of low C3 and low C4 complement levels, followed by class II/V lupus nephritis, either low C3 or low C4 complement levels, delirium and psychosis, when these were not attributable to non-SLE causes. CONCLUSIONS In this cohort from an independent academic medical centre, the sensitivity and specificity of the 2019 lupus classification criteria were confirmed. Overall agreement of the 1997 and the 2019 criteria was very good.

Abstract
Neuromyelitis optica spectrum disorder (NMOSD) is a disease of the central nervous system and the optic nerves that disproportionately affects women and occasionally coexists with other autoimmune diseases. NMOSD manifesting as skin lesions is a rare phenomenon. Furthermore, these skin lesions in the setting of NMOSD during pregnancy have not been described. We report the case of a 31-year-old woman from sub-Saharan Africa who presented with initial recurrent skin lesions followed by paraparesis during her second trimester of pregnancy. Her next pregnancy was associated with sudden vision loss. She had positive serology for aquaporin-4 antibodies and subsequently developed a positive dsDNA antibody two years after the initial NMOSD diagnosis. Her skin lesions and symptoms improved following the administration of azathioprine. This case highlights the impact of pregnancy on NMOSD and the significance of a heightened level of suspicion for NMOSD in patients who exhibit recurring skin lesions preceding paraparesis events.

Abstract
Background Autoantibodies are vital biomarkers for the diagnosis, assessment and prognostic determination of various autoimmune disorders. Objective This study aimed to evaluate the performance of the two AtheNA Multi-Lyte® systems for the detection of various autoantibodies. Methods A total of 105 systemic lupus erythematosus patients, 35 patients with other autoimmune diseases (diseased controls), and 30 healthy volunteers (healthy controls) at Zagazig University Hospitals, Zagazig city, Al Sharqia governorate were tested for anti-double-stranded DNA (anti-dsDNA) antibodies using indirect immunofluorescence (IIF) and the AtheNA Multi-Lyte® anti-nuclear antibodies-II system between May 2020 and April 2022. Seventy-five patients with clinically suspected autoimmune vasculitis (AIV) and 25 healthy volunteers were also tested for anti-myeloperoxidase and anti-proteinase 3 antibodies using IIF, the AtheNA Multi-Lyte® AIV system, and enzyme-linked immunosorbent assay (ELISA). Results The AtheNA anti-dsDNA test (98.5%) was more specific than IIF (96.9%) for diagnosing systemic lupus erythematosus, but both tests had the same sensitivity (38.1%). Combining both methods increased sensitivity to 47.6%, while increasing the cut-off of the AtheNA anti-dsDNA test to 134 international units/mL increased specificity to 100%. The AtheNA Multi-Lyte AIV system exhibited substantial agreement with IIF regarding anti-myeloperoxidase testing (κ = 0.65) and almost perfect agreement with ELISA (κ = 0.85). The AtheNA Multi-Lyte® AIV system exhibited perfect agreement with IIF (κ = 1) and substantial agreement with ELISA for anti-proteinase 3 testing (κ = 0.63). Conclusion AtheNA Multi-Lyte® systems appear to be reliable for anti-dsDNA, anti-myeloperoxidase, and anti-proteinase 3 screening and may be an optimal choice for monitoring anti-dsDNA levels. What this study adds It is necessary to evaluate various autoantibodies detection assays to increase both sensitivity and specificity of autoimmune diseases diagnostic approaches. AtheNA Multi-Lyte® systems appear to be reliable for anti-dsDNA, anti-myeloperoxidase, and anti-proteinase 3 screening and may be an optimal choice for monitoring anti-dsDNA levels.

Abstract
Overlap syndrome is a connective tissue disorder that satisfies the diagnostic criteria for at least two well-known autoimmune diseases. In this report, we describe a rare case of lupus overlap in an elderly woman with primary Sjögren's syndrome who presented with features of nephritic-nephrotic syndrome and renal biopsy results typical of lupus nephritis combined with multiple positive autoantibodies. The kidney biopsy results were assigned the highest weightage based on the revised 2019 systemic lupus erythematosus (SLE) classification criteria developed by the European League Against Rheumatism (EULAR) and the American College of Rheumatology (ACR). The patient's condition significantly improved after appropriate immunosuppressive therapy was initiated. With the revised ACR/EULAR-2019 criteria, we anticipate that more SLE patients with typical lupus nephritis biopsy findings will be diagnosed accurately.

Abstract
BACKGROUND Semaphorin 4A (Sema4A) is an immunoregulatory molecule that is closely related to the pathogenesis of some autoimmune diseases. However, the relationship between Sema4A and systemic lupus erythematosus (SLE) remains unknown. We therefore aimed to investigate the expression and clinical value of Sema4A in SLE patients. METHODS Patients with SLE, rheumatoid arthritis (RA), and healthy controls (HC) were enrolled. The whole blood samples were collected from SLE (83), RA (29) and HC (85), and the expression of Sema4A on several types of leukocytes in peripheral blood was detected by flow cytometry. The serum samples were collected from SLE(77), RA (23) and HC (63), and the concentrations of soluble Sema4A in plasma were detected by ELISA. The diagnostic value of membrane-bound and soluble Sema4A in SLE patients was evaluated using a receiver operating characteristic (ROC) curve. RESULTS The concentration of soluble Sema4A was significantly higher in plasma from SLE patients compared to that from HC and RA patients. In SLE patients, the ratio of CD4+CD11c+ myeloid dendritic cells (mDCs) expressing Sema4A increased significantly, and the levels of soluble Sema4A and membrane-bound Sema4A were negatively correlated with the levels of C3 and C4, respectively. The same result was observed for membrane-bound Sema4A on CD4+CD11c+ mDCs cells. In addition, the level of soluble Sema4A negatively correlated with the concentration of hemoglobin (Hb). Importantly, the expression ratio of membrane-bound Sema4A on CD4+CD11c+ mDCs was positively correlated with systemic lupus erythematosus disease activity index (SLEDAI). Finally, we revealed that soluble and membrane- bound Sema4A had high sensitivity and specificity for diagnosis of SLE, and had a greater ability to distinguish between SLE and RA. CONCLUSION Sema4A has potential as a new diagnostic biomarker for SLE, and is promising for distinguishing between SLE and RA.

Abstract
In this pilot study, we aim to determine differences in pathogenetic pathways between interstitial pneumonia with autoimmune features (IPAF), connective-tissue-disease-associated interstitial lung diseases (CTD-ILDs), and idiopathic interstitial pneumonias (IIPs). Forty participants were recruited: 9 with IPAF, 15 with CTD-ILDs, and 16 with IIPs. Concentration of transforming growth factor beta (TGF-β1), surfactant proteins A and D (SP-A, SP-D), interleukin 8 (IL-8), and chemokine 1 (CXCL1) were assessed with ELISA assay in bronchoalveolar lavage (BAL) fluid. We revealed that IL-8 and TGF-β1 concentrations were significantly lower in the IPAF group than in the CTD-ILD group (p = 0.008 and p = 0.019, respectively), but similar to the concentrations in the IIP group. There were significant correlations of IL-8 (rs = 0.46; p = 0.003) and CXCL1 (rs = 0.52; p = 0.001) and BAL total cell count (TCC). A multivariate regression model revealed that IL-8 (β = 0.32; p = 0.037) and CXCL1 (β = 0.45; p = 0.004) are significant predictors of BAL TCC. We revealed that IL-8 and TGF-β1 BAL concentrations vary in patients with different ILDs and found that IL-8 is a predictor of BAL TCC in IPAF. However, this needs to be confirmed in a multicenter cooperative study (ClinicalTrials.gov Identifier: NCT03870828).

Abstract
BACKGROUND Systemic diseases of pediatric onset are more frequent in the Afro-Caribbean population. We performed a study of patients followed in the French overseas departments of America (FOAD) for pediatric systemic lupus erythematosus (pSLE). The aims were to describe the clinical and biological specificities during childhood in this population. METHODS A retrospective study was conducted between January 2000 and September 2021. Patients with pSLE were identified from multiple sources: computerized hospital archives, registry of referring pediatricians, adult specialists in internal medicine and the French National Registry for rare diseases. We studied SLE with pediatric onset defined by international criteria. RESULTS Overall, 2148 patients were identified, of whom 54 were included. The average follow-up was 8.3 years (range: 0.3-25 years). We observed an increase in new diagnoses over time. At onset, pSLE patients had a median of 10 SLICC criteria (range: 4-12), and the median EULAR/ACR 2019 score was 38 (12-54). At onset, one third of patients had renal involvement, 15% had neurolupus and 41% cardiac involvement. During childhood, 54% had renal involvement, and 26% suffered from neurolupus. Patients suffered a median of 3 flares during childhood, and 26% had more than 5 flares. Patients with younger age at onset had worse outcomes than those who were older at diagnosis, i.e., more flares (median 5, p = 0.02) and requiring an average of 4 background therapies (p = 0.04). CONCLUSION The outcomes of Afro-Caribbean patients were similar to those in Western population, but with worse disease activity at onset. Further studies should be performed to identify the genetic and environmental factors in this population.

Abstract
Objective Sensitivity and specificity of SLE classification criteria may vary in different populations and clinical settings. In this study, we aimed to compare the performances of three criteria sets/rules (1997, 2012, and 2019) in a large cohort of patients and relevant diseased controls. Methods The medical records of consecutive SLE patients and diseased controls were reviewed for clinical and laboratory features relevant to all sets of criteria. Criteria sets/rules were analyzed based on sensitivity, positive predictive value, specificity, and negative predictive value, using clinical diagnosis with at least 6 months of follow-up as the gold standard. A subgroup analysis was performed in ANA positive patients. Results A total of 393 SLE patients and 308 non-SLE diseased controls were included. Sensitivity was 78.4% for 1997 criteria and was more than 90% for both 2012 (91.9%) and 2019 (94.4%) criteria. Specificity was the highest (95.1%) for 1997 ACR criteria, 91.5% for 2012 SLICC criteria and 91.2% for 2019 EULAR/ACR criteria. When only ANA positive patients were analyzed, sensitivity of each criteria increased by 1%, 0.8%, and 2.2%, respectively. Specificity of 1997 criteria decreased by 2% and specificity of 2012 and 2019 criteria both decreased to less than 90%. Conclusion EULAR/ACR criteria were more sensitive than 1997 criteria and had a comparable performance with SLICC criteria. When only ANA positive patients were analyzed, the presence of false positive results (originated from patients with Sjögren’s disease and antiphospholipid syndrome mainly) decreased the specificity of both SLICC and EULAR/ACR criteria.

Abstract
Background The Renal Activity Index for Lupus (RAIL) is a composite score of six urinary biomarkers (neutrophil gelatinase-associated lipocalin (NGAL), monocyte chemoattractant protein-1 (MCP-1), kidney injury molecule-1 (KIM-1), ceruloplasmin, adiponectin, and hemopexin) used to monitor lupus nephritis activity in children. We tested stability of RAIL biomarkers prior to meaningful clinical use. Methods Urine samples were tested by ELISA under shipping conditions, freeze/thaw, ambient and longer-term storage. Statistical analysis was performed via Deming Regression, Bland-Altman and Spearman Correlation Coefficient. Results Biomarker concentration were comparable to freshly collected urine following storage at -80 °C for up to 3 months, and at 4 or 25 °C up to 48 h followed by -80 °C. Neither shipping on dry or wet ice exposure nor addition of two freeze-thaw cycles led to loss of signal, with excellent Spearman Correlation coefficients under all conditions. Conclusions RAIL biomarkers are stable following short-term storage at clinically relevant conditions.

Case Report: Rapid Progression of Cognitive Dysfunction as an Initial Feature of Systemic Lupus Erythematosus With Leukoencephalopathy: A Case Report and Literature Review. Front Neurol 2022; 13:934335. [PMID: 35899269 PMCID: PMC9309334 DOI: 10.3389/fneur.2022.934335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Accepted: 06/23/2022] [Indexed: 12/02/2022] Open
Abstract
Neuropsychiatric systemic lupus erythematosus (NPSLE) has been considered to have high morbidity and mortality. Thus, earlier recognition and treatment are of great importance. However, the rapid progression of cognitive dysfunction with leukoencephalopathy as an initial presentation in SLE is rarely described. We report a case in which an elderly man experienced rapidly progressive cognitive impairment with bilateral, symmetric, and diffuse leukoencephalopathy with lasting diffusion-weighted image hyperintensity. An immunological workup showed low complement levels and positivity for antinuclear antibody -speckle and Coombs tests in the patient's serum samples. He had an appropriate improvement in cognitive function after receiving a combination of various immunotherapies. Long-term follow-up showed clinical improvement, including rheumatological labs and neuroimaging. A review of the literature on NPSLE with leukoencephalopathy and a summary of all reported cases to date are also presented. Our case indicated that isolated leukoencephalopathy in NPSLE, as an indicator of severe NPSLE, can be recognized early. Immunotherapy is warranted given the possibility of clinical improvement.

Abstract
OBJECTIVES To analyze and evaluate the effectiveness of the detection of single autoantibody and combined autoantibodies in patients with rheumatoid arthritis (RA) and related autoimmune diseases and establish a machine learning model to predict the disease of RA. METHODS A total of 309 patients with joint pain as the first symptom were retrieved from the database. The effectiveness of single and combined antibodies tests was analyzed and evaluated in patients with RA, a cost-sensitive neural network (CSNN) model was used to integrate multiple autoantibodies and patient symptoms to predict the diagnosis of RA, and the ROC curve was used to analyze the diagnosis performance and calculate the optimal cutoff value. RESULTS There are differences in the seropositive rate of autoimmune diseases, the sensitivity and specificity of single or multiple autoantibody tests were insufficient, and anti-CCP performed best in RA diagnosis and had high diagnostic value. The cost-sensitive neural network prediction model had a sensitivity of up to 0.90 and specificity of up to 0.86, which was better than a single antibody and combined multiple antibody detection. CONCLUSION In-depth analysis of autoantibodies and reliable early diagnosis based on the neural network could guide specialized physicians to develop different treatment plans to prevent deterioration and enable early treatment with antirheumatic drugs for remission. Key Points • There are differences in the seropositive rate of autoimmune diseases. • This is the first study to use a cost-sensitive neural network model to diagnose RA disease in patients. • The diagnosis effect of the cost-sensitive neural network model is better than a single antibody and combined multiple antibody detection.

Abstract
Background Chronic kidney disease (CKD) is a major public health issue because of the rising number of patients with the risk of progression to end-stage renal disease. The retinal micro-vasculatures provide a unique window to assess systemic microcirculation. Optical Coherence Tomography Angiography (OCTA) parameters may provide a non-invasive method for systemic correlation. This research aims to compare the association of OCTA parameters in different causes of CKD. Methods This is a single-center cross-sectional study on patients with CKD at the Universiti Kebangsaan Malaysia Medical Centre over 2 years. Patients with CKD were divided into three groups: DM group (diabetic CKD), HPT group (hypertensive CKD), and AG group (autoimmune-related glomerulonephritis CKD). The OCTA parameters, namely, the foveal avascular zone (FAZ), vascular density (VD), perfusion density (PD), and macular volume (MV), were measured and recorded using OCTA. Blood and urine analyses were taken as the patient's CKD profile. The demographic data, the OCTA parameters and the CKD profiles, were analyzed using SPSS version 23. Results The right eyes of 232 patients were included. The median age of the control and CKD subjects were 36 and 61 years old respectively. The proportion of the subjects under the control, diabetes mellitus (DM), HPT, and AG group were 30.6, 53.4, 5.6, and 10.4% respectively. There was no significant difference in FAZ, but there is a significant difference in the VD, PD, and MV between the control and CKD groups. There was a statistically significant difference between the three different causes of CKD in VD and PD (p < 0.001, p = 0.001, respectively). When compared with the control group for VD and PD, there were significant differences between the DM-control group (p < 0.001, p < 0.001) even when the age variable was considered, but no significant difference when comparing the HPT-control and the AG-control. There was a significant correlation between age, FBS, and HbA1c with VD and PD. There was no significant association between CKD profile and FAZ. Conclusion Our study showed the meaningful reduction of VD and PD in patients with diabetes and CKD. However, the use of OCTA to screen or predict CKD in patients living with diabetes mellitus, hypertension, or autoimmune nephritis was not shown to be useful.

Abstract
Background Systemic sclerosis (SSc) may overlap with other connective tissue diseases, which is named overlap syndrome. Scleroderma renal crisis (SRC) is a rare but severe complication of SSc. SSc related thrombotic microangiopathy (SSc-TMA) is an infrequent pathology type of SRC, while SSc-TMA accompanied by overlap syndrome is very rare. Case presentation This study reported a case of acute kidney injury (AKI) accompanied with overlap syndrome of SSc, systemic lupus erythematosus (SLE) and polymyositis (PM). The renal pathology supported the diagnosis of SSc-TMA but not SLE or PM-related renal injury, characterized by renal arteriolar thrombosis, endothelial cells edema, little cast in tubules and mild immune complex deposition. The primary TMA related factors (ADAMTS13 and complement H factor) were normal. Thus, this case was diagnosed as secondary TMA associated with SSc. The patient was treated with renin angiotensin system inhibitors, sildenafil, supportive plasma exchange/dialysis, and rituximab combined with glucocorticoids. After 2 months of peritoneal dialysis treatment, her renal function recovered and dialysis was stopped. Conclusion This study presented a case of SSc-TMA with overlap syndrome. Rituximab can be used as a treatment option in patients with high SRC risk or already manifesting SRC.

Abstract
In systemic lupus erythematosus (SLE), cardiac manifestations are known to be present in up to 50% of patients. However, it is rare for acute pericarditis to be the leading symptom at the time of diagnosis of SLE occurring in up to 1% of patients. We present a case series in which 3 patients with no prior history of SLE presented with acute pericarditis. This was found to be the leading manifestation of their disease, which ultimately led to the diagnosis of SLE. These patients were initially treated with nonsteroidal anti-inflammatory drugs and colchicines; however, steroids and disease-modifying anti-rheumatologic agents were ultimately added to their medical therapy.

Abstract
Purpose: The aim of this study was to determine the spectrum of eye disorders in patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Materials and Methods: A cross-sectional hospital-based study was conducted among 100 consecutive patients with RA and SLE. A semi-structured questionnaire was used to obtain details of patients’ sociodemographics, type of rheumatic disease, and prescribed medications. Each patient had a detailed examination of the anterior and posterior segments of the eye. Refraction, intraocular pressure measurement, Schirmer’s test, tear breakup time, gonioscopy, and dilated fundoscopy were also done. Fundus photograph, central visual field assessment, and optical coherence tomography were done as necessary. Analysis was done with the Statistical Package for Social Sciences (SPSS) version 25. Statistical significance was set at P < 0.05. Results: A total of 100 patients consisting of 74 RA and 26 SLE patients were evaluated. The female: male ratio was 4.3: 1 for RA, and all SLE patients were females. The prevalence of eye disorders was 42% in all patients; it was 41.9% and 42.3% among RA and SLE patients, respectively. The most common eye disorders were dry eye (38), refractive errors (18), and cataract (16). The mean age of RA patients with eye disorders (52.19 ± 16.17 years) was significantly higher than those without eye disorders (42.30 ± 13.14 years) (P = 0.005). Conclusion: Eye disorders are common in RA and SLE. Comprehensive eye examination should be done on all RA and SLE patients at diagnosis and before commencement of medications, and patients should be referred promptly for evaluation when they have eye complaints.

Abstract
A subset of interstitial lung diseases (ILDs) with autoimmune traits-including connective tissue disease-associated ILD (CTD-ILD) and interstitial pneumonia with autoimmune features (IPAF)-develops progressive fibrosing (PF)-ILD. The aim of our study was to evaluate the clinical characteristics and predictors of longitudinal lung function (LF) changes in autoimmune PF-ILD patients in a real-world setting. All ILD cases with confirmed or suspected autoimmunity discussed by a multidisciplinary team (MDT) between January 2017 and June 2019 (n = 511) were reviewed, including 63 CTD-ILD and 44 IPAF patients. Detailed medical history, LF test, diffusing capacity of the lung for carbon monoxide (DLCO), 6-min walk test (6MWT), blood gas analysis (BGA), and high-resolution computer tomography (HRCT) were performed. Longitudinal follow-up for functional parameters was at least 2 years. Women were overrepresented (70.1%), and the age of the IPAF group was significantly higher as compared to the CTD-ILD group (p < 0.001). Dyspnea, crackles, and weight loss were significantly more common in the IPAF group as compared to the CTD-ILD group (84.1% vs. 58.7%, p = 0.006; 72.7% vs. 49.2%, p = 0.017; 29.6% vs. 4.8%, p = 0.001). Forced vital capacity (FVC) yearly decline was more pronounced in IPAF (53.1 ± 0.3 vs. 16.7 ± 0.2 ml; p = 0.294), while the majority of patients (IPAF: 68% and CTD-ILD 82%) did not deteriorate. Factors influencing progression included malignancy as a comorbidity, anti-SS-A antibodies, and post-exercise pulse increase at 6MWT. Antifibrotic therapy was administered significantly more often in IPAF as compared to CTD-ILD patients (n = 13, 29.5% vs. n = 5, 7.9%; p = 0.007), and importantly, this treatment reduced lung function decline when compared to non-treated patients. Majority of patients improved or were stable regarding lung function, and autoimmune-associated PF-ILD was more common in patients having IPAF. Functional decline predictors were anti-SS-A antibodies and marked post-exercise pulse increase at 6MWT. Antifibrotic treatments reduced progression in progressive fibrosing CTD-ILD and IPAF, emphasizing the need for guidelines including optimal treatment start and combination therapies in this special patient group.

Salivary gland ultrasonography in patients with connective tissue diseases: a multi-center observational study. Rheumatology (Oxford) 2021; 61:3362-3369.

Abstract
OBJECTIVE Ultrasonography (US) of salivary glands (SGUS) is a non-invasive tool that allows for diagnosing primary Sjögren's syndrome (pSS) or secondary SS (sSS). However, little is known about the prevalence of US findings of SS in other connective tissue diseases (CTDs). The aim of this multicentre observational study was to evaluate, in CTD patients with or without SS, the prevalence of abnormal SGUS findings and the possible association of the findings with clinical or biological phenotypes. METHODS B-Mode SGUS was performed by one operator blinded to clinical data. Each SG was semi-quantitatively rated on a scale from 0-4 according to the Jousse-Joulin score; a score ≥ 2 was considered pathological. RESULTS Data for 194 patients were analyzed (pSS, n = 30; sSS, n = 39; other CTDs, n = 77; controls, n = 48). SGUS findings were abnormal in 80%, 67%, 25% and 2% of patients, respectively. Independent of the underlying disease, age and sex, abnormal SGUS findings were significantly associated with presence of anti-SSA antibodies (p< 0.001), pSS (p< 0.001) and sSS (p< 0.01). Among SS patients, abnormal SGUS findings were associated with the presence of hypergammaglobulinemia, anti-SSA antibodies, objective eye dryness and increased anti-nuclear antibody level, with no difference in EULAR Sjögren's Syndrome Disease Activity Index. CONCLUSION Abnormal SGUS findings were associated with anti-SSA antibody positivity independent of the underlying disease. In SS patients, abnormal findings were associated with immunologic features and mouth involvement. Among CTD patients, SGUS changes may be associated with a particular immune profile.

Clin Rheumatol 2021; 41:1079-1085. [PMID: 34782939 DOI: 10.1007/s10067-021-05989-w] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Revised: 10/09/2021] [Accepted: 11/08/2021] [Indexed: 12/28/2022]
Abstract
The objective of this study is to assess the role of the 2019-European League Against Rheumatism/American College of Rheumatology (2019-EULAR/ACR) classification criteria at diagnosis and its domains in predicting long-term damage in systemic lupus erythematosus(SLE). We performed a retrospective analysis using an electronic chart database utilized in routine clinical care of SLE patients and established in 2000 in a tertiary hospital. Two hundred and nine consecutive SLE patients with disease onset ≥18 years old and long disease duration were included. Cumulative damage at the last visit was scored using the SLICC/ACR-Damage Index (SDI). The median age at SLE diagnosis was 28 years (18-63), disease duration was 14 years (8-25), and 88% were females. Damage (SDI≥1) was observed in 116/209 (55%). Patients with (SDI≥1, n=116) and without damage (SDI=0, n=93) had similar median disease duration [14 (8-25) vs. 12 (8-25) years, p=0.090] and age at diagnosis [23 (18-55) vs. 23 (18-56) years, p=0.998]. No correlation was observed between total 2019-EULAR/ACR score at diagnosis and SDI at last visit (r=0.007, p=0.913). Presence of renal domain at diagnosis was associated with renal damage at last visit (OR=3.6, 95%CI 1.2-10.4, p=0.017) and antiphospholipid antibodies domain predicted neuropsychiatric damage (OR=3.0, 95%CI 1.2-7.6, p=0.015). A ROC analysis identified that a cut-off >24 in 2019-EULAR/ACR score could predict a trend for renal damage (p=0.077) with a lower renal survival (Kaplan-Meier curve) for patients above this limit (p=0.029). A multivariate logistic regression analysis revealed that 2019-EULAR/ACR score >24 at diagnosis (OR 4.583, 95%CI 1.052-19.962, p=0.043) was independently associated with renal damage. Specific domains in the 2019-EULAR/ACR criteria at diagnosis were associated with long-term organ-specific damage, particularly renal and neuropsychiatric harm. A 2019-EULAR/ACR score >24 predicted worse renal survival. Key Points • Presence of renal domain of the 2019-EULAR/ACR classification criteria at diagnosis was associated with long-term renal damage. • Presence of antiphospholipid antibodies domain at diagnosis was associated with long-term neuropsychiatric damage. • A 2019-EULAR/ACR overall score >24 at diagnosis was independently associated with renal damage and predicted worse renal long-term survival.
