Abstract
OBJECTIVE The aim of this study was to characterize childhood-onset systemic lupus erythematosus (SLE) in two large cohorts from Turkey and the United States. METHODS Patients diagnosed with childhood-onset SLE who fulfilled the 1997 American College of Rheumatology classification criteria for SLE from four reference centers in Turkey and the University of Pittsburgh School of Medicine in the United States were included in this study. A comparative analysis was conducted to evaluate the similarities and differences in clinical and laboratory features, damage accrual, and treatment experiences between the two populations. RESULTS A total of 174 patients with childhood-onset SLE were included in this study (108 patients from Turkey and 66 patients from the United States). The female-to-male ratio was similar between the two cohorts (∼3:1, p = .73). The median age at diagnosis was 11.67 years (2.19-17.93) in the Turkish cohort and 13.68 years (2.74-17.93) in the U.S. cohort (p < .001). Photosensitivity (45.4% and 21.2%; p = .007) and renal involvement (41.7% and 36.4%; p = .045) were higher in the Turkish cohort. Anti-Ro/SSA (34.8% and 15.7%; p < .001), anti-Sm (59.1% and 19.4%; p < .001), and anti-RNP (47.0% and 14.8%; p < .001) positivity was more frequent in the U.S. cohort. Current use of rituximab (37.9% and 1.9%; p < .001) and belimumab (19.7% and 0%; p < .001) was more prevalent in the U.S. cohort, while the use of cyclophosphamide (often according to the low dose Euro-Lupus protocol) throughout the disease course (24.1% and 4.5%; p < .001) was more frequent in the Turkish cohort. SLICC/ACR Damage Index scores were not different between the two cohorts. CONCLUSION This study provides detailed clinical and laboratory features of childhood-onset SLE in two independent and geographically divergent cohorts. Our findings suggest an earlier age of disease onset and a higher prevalence of kidney involvement in Turkish patients. Differences in treatment approaches were also noted. However, damage accrual related to SLE does not appear to be different between the two patient populations.

Abstract
This study aims to analyze the clinical and immunologic features of SLE in Jordan, while also investigating the impact of age and gender on disease presentation. The study included 275 patients diagnosed with SLE. Data were collected through meticulous patient interviews and thorough examination of patient hospital records. The cohort exhibited a mean age of 36.8 ± 12.9 years, with an average disease duration of 7.0 ± 7.8 years. The mean age at diagnosis was 29.9 ± 12.1 years, and the female to male ratio was 7.8:1. The most frequently observed symptoms were arthralgia (90.2%), fatigue (80.7%), hematologic manifestations (62%), photosensitivity (60.7%), Raynaud's phenomenon (53.5%), and malar rash (50.9%). The frequencies of various autoantibodies were as follows: ANA (96.7%), anti-dsDNA (39.6%), anti-SSA/Ro (32.8%), anti-Sm (21.8%), anti-U1-RNP (20.6%), and anti-SSB/La (15.5%). Male patients tended to receive a diagnosis at a younger age and exhibited a higher likelihood of experiencing severe manifestations compared to females. Additionally, juvenile onset patients demonstrated an increased likelihood of fever, photosensitivity, myositis, and anti-dsDNA autoantibodies, while adult onset patients were more predisposed to having anti-Ro, anti-La, and RF autoantibodies. This study reveals that the most prevalent manifestations of SLE in the Jordanian cohort encompassed arthralgia, fatigue, and hematologic manifestations. The prevalence of alopecia and Raynaud's phenomenon exceeded that observed in other published cohorts, while arthritis and discoid rash were less frequently encountered. The study highlights that males are more susceptible to developing severe manifestations of SLE compared to females.

Abstract
BACKGROUND Neuropsychiatric systemic lupus erythematosus (NPSLE) is a major contributor to morbidity and mortality in systemic lupus erythematosus (SLE) patients. To date no single clinical, laboratory or imaging test has proven accurate for NPSLE diagnosis which is a testament to the intricate and multifactorial pathophysiological mechanisms suspected to exist. Functional imaging with FDG PET-CT has shown promise in NPSLE diagnosis, detecting abnormalities prior to changes evident on anatomical imaging. Research indicates that NPSLE may be more aggressive in people of African descent with higher mortality rates, making rapid and correct diagnosis even more important in the African context. METHODS In this narrative review, we provide a thorough appraisal of the current literature on the role of FDG PET-CT in NPSLE. Large, well-known databases were searched using appropriate search terms. Manual searches of references of retrieved literature were also included. FINDINGS A total of 73 article abstracts were assessed, yielding 26 papers that were directly relevant to the topic of FDG PET-CT in NPSLE. Results suggest that FDG PET-CT is a sensitive imaging test for NPSLE diagnosis and may play a role in assessing treatment response. It is complementary to routine anatomical imaging, particularly in diffuse manifestations of the disease. Newer quantitative analyses are commonly used for interpretation and can detect even subtle abnormalities, missed on visual inspection. Findings of group-wise analyses of FDG PET-CT scans in NPSLE patients are important in furthering our understanding of the complicated pathophysiological mechanisms involved. Limitations of FDG PET-CT include its lack of specificity, high cost and poor access. CONCLUSION FDG PET-CT is a sensitive test for NPSLE diagnosis but is hampered by lack of specificity. It is a valuable tool for clinicians managing SLE patients, particularly when anatomical imaging is negative. Its exact application will depend on the local context and clinical scenario.

Abstract
OBJECTIVE Systemic lupus erythematosus (SLE) is an autoimmune disease resulting in debilitating clinical manifestations that vary in severity by race and ethnicity with a disproportionate burden in African American, Mestizo, and Asian populations compared with populations of European descent. Differences in global and local genetic ancestry may shed light on the underlying mechanisms contributing to these disparities, including increased prevalence of lupus nephritis, younger age of symptom onset, and presence of autoantibodies. METHODS A total of 1,139 European, African American, and Mestizos patients with SLE were genotyped using the Affymetrix LAT1 World array. Global ancestry proportions were estimated using ADMIXTURE, and local ancestry was estimated using RFMIXv2.0. We investigated associations between lupus nephritis, age at onset, and autoantibody status with both global and local ancestry proportions within the Major Histocompatibility Complex region. RESULTS Our results showed small effect sizes that did not meet the threshold for statistical significance for global or local ancestry proportions in either African American or Mestizo patients with SLE who presented with the clinical manifestations of interest compared with those who did not. CONCLUSION These findings suggest that local genetic ancestry within the Major Histocompatibility Complex region is not a major contributor to these SLE manifestations among patients with SLE from admixed populations.

Abstract
OBJECTIVE This retrospective study aimed to conduct a comprehensive analysis of Turkish Systemic Lupus Erythematosus (SLE) patients of Caucasian ethnicity, focusing on their clinical, immunological, and therapeutic characteristics, damage accural and mortality. PATIENTS AND METHODS We carried out a retrospective assessment of 300 SLE patients diagnosed between 2001 and 2017 at Kocaeli University Rheumatology Clinic. Demographic data, clinical manifestations, immunological profiles, treatment approaches, disease-related damage, and survival information were collected. RESULTS The study population had a significant female predominance (89%) with a mean age of disease onset of 35.4 (SD:13.3) years. Hematological (72.6%) and mucocutaneous (72%) manifestations were the most common clinical findings, followed by arthritis (66.3%). Females had higher frequency of photosensitivity (p = 0.019), malar rash (p < 0.001), and alopecia (p = 0.014). Anti-dsDNA antibodies were detected in 61.6% of patients, while 57% of patients had hypocomplementemia. Secondary antiphospholipid syndrome was observed in 15.3% of patients; the most common manifestations included deep venous thrombosis (32.6%) and cerebrovascular accidents (30.4%). Lupus Nephritis (LN) affected 40.3% of the cohort. The most common pathologic finding was Class IV LN (30.5%). Eventually, 13 (4.3%) patients developed chronic kidney disease (CKD) and 4 had renal replacement therapies. Patients with LN had higher usage of pulse steroids, azathioprin, mycophenolate mofetil, cyclophosphamide, and rituximab (p < 0.001 for each). In the juvenile-onset group (n = 31, 10.3%), an increased occurrence of malar rash (p = 0.009), nephritis (p = 0.034), hypocomplementemia (p = 0.001), positive anti-dsDNA (p = 0.007), anti-Sm (p = 0.046), anti-rib-P (p = 0.014) antibodies were observed. At least one damage parameter was observed in 32.6% patients with musculoskeletal manifestations being the most common. Thirteen patients were diagnosed with various malignancies, with cervical cancer being the most common (4 cases). The total 5 and 10-year survival rates were 92.5% and 86.7%, respectively. However, patients with CKD, had lower survival rates; 75% at 3 years and 60% at 15 years. Regression analysis demonstrated an association of CKD and history of infections with decreased survival (p = 0.02, each). CONCLUSION Ethnicity and geography influence the clinical diversity of SLE. Recognizing these disparities is crucial for tailoring patient care. Future inception cohort studies in Turkish SLE patients are necessary to address the limitations of retrospective research.

Abstract
OBJECTIVES Systemic lupus erythematosus (SLE) with a high morbidity rate (7% in general and 325/100.000 in reproductive period) was known as "the mother of autoimmune diseases." But healthcare providers hadn't reliable scales to measure the effectiveness of interventions to improve reproductive health. Women with systemic lupus erythematosus (SLE) express concern about a significant gap in their reproductive and sexual health during medical care due to the lack of a specific scale to measure this concept. This study developed psychometrically specific scale to evaluate this concept in Iranian women. METHODS The study utilized a sequential-exploratory mixed-methods design, wherein the concept of reproductive health was clarified during the qualitative phase using conventional content analysis (inductive-deductive) to create a pool of RHASLE (Reproductive Health Assessment in SLE) items. During the psychometric process, the face, content, and construct validities of the RHASLE were checked with 650 individuals (320 using exploratory factor analysis [EFA] and 330 using confirmatory factor analysis [CFA]) through interviews and completion of the questionnaire. Convergent and divergent validities were then checked, and the reliability was assessed through stability and internal consistency. Finally, the measurement error, responsiveness, and interpretability of the scale were evaluated and confirmed. RESULTS The study's findings revealed that the RHASLE consisted of 5 factors (33 items): physical-psychological disorder (13 items), relaxing feeling (6 items), spirituality (3 items), high-risk pregnancies (5 items), and sexual satisfaction (6 items). These factors explained a total of 99.97% of the variance in the concept of reproductive health. Confirmatory factor analysis confirmed the good model fit, and its validity and reliability were deemed acceptable. CONCLUSION The RHASLE consisted of 27 items with high internal consistency, stability, responsiveness, and interpretability. That was able to get approval of Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist. Based on the results, RHASLE is a valid and reliable multidimensional scale that encompasses various aspects of reproductive health (physical, sexual, psychological, social, and spiritual).

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that can cause a range of symptoms, including oral mucosal lesions (OMLs). The prevalence of OMLs in SLE patients and their associated factors have been studied in various regions, but the results are inconsistent. This study aims to evaluate the prevalence of OMLs in patients with SLE. METHODS Observational studies of OML prevalence in SLE patients published before 2022 were retrieved from PubMed, Embase, Web of Science, Google Scholar, and the Cochrane Library without language restriction. The quality of the studies was assessed using the Newcastle-Ottawa Scale (NOS) and Agency for Healthcare Research and Quality (AHRQ). RESULTS Our meta-analysis included 113 studies with a total of 53,307 SLE patients. We found that the prevalence of OMLs in SLE patients was 31% (95% CI: 28%, 35%), with oral ulcers being present in 30% of SLE patients (95% CI: 26%, 33%). Subgroup analysis showed that the prevalence of OMLs varied significantly by region, disease activity, and sample size (p ≤ 0.01). However, gender and year of publication had little effect on the prevalence of OMLs (p = 0.78 and 0.30, respectively). Oral ulcers were significantly associated with age of onset (p = 0.02), geographic location (p < 0.01), and race (p < 0.01). We also found that the prevalence of oral erythema was 9%, oral candidiasis was 9%, petechiae was 8%, cheilitis was 6%, and white plaque was 3%. CONCLUSIONS Our analysis showed that the prevalence of OMLs varied significantly by region and disease activity, and child-onset patients of Indian, Malay, and Caucasian descent were more likely to have oral ulcers. The high prevalence of OML in SLE patients emphasizes the importance of regular oral examination and management in the comprehensive care of individuals with SLE.

Abstract
Although psoriasis and systemic lupus erythematosus are both immune abnormalities, there are few reports on Ps combined with SLE in China and abroad. We present a case of a 23-year-old female with a 10-year history of psoriasis, who had a relapse with significant joint symptoms and a PASI score of 35.6, along with several positive antibodies, including antinuclear antibodies, elevated CRP and ESR, and was diagnosed with psoriasis and SLE. She has been treated with secukinumab 300 mg subcutaneously, improving her condition. She is currently being followed up. The PubMed, SCOPUS, and ISI Web of Science databases were thoroughly searched for English studies reporting psoriasis with systemic lupus erythematosus and treated using biologics. Three case reports/series were included after the screening. Our case report provides a reference for clinicians using secukinumab to treat psoriasis combined with SLE. However, further research is needed to determine whether it can be widely used or if there are common signaling pathways that can be interfered with the pathogenesis of the diseases.

Abstract
OBJECTIVE Growing evidence suggests psychosocial stressors may increase risk of developing autoimmune disease. We examined stressful life events and caregiving in relation to incident rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) in the Women's Health Initiative Observational Study cohort. METHODS The sample of postmenopausal women included 211 incident RA or SLE cases reported within 3 years after enrollment, confirmed by use of disease-modifying antirheumatic drugs (i.e., probable RA/SLE), and 76,648 noncases. Baseline questionnaires asked about life events in the past year, caregiving, and social support. We used Cox regression models to calculate hazard ratios (HR) and 95% confidence intervals (95% CIs), adjusting for age, race/ethnicity, occupational class, education, pack-years of smoking and BMI. RESULTS Incident RA/SLE was associated with reporting 3 or more life events (e.g., age-adjusted HR 1.70 [95% CI 1.14, 2.53]; P for trend = 0.0026). Elevated HRs were noted for physical (HR 2.48 [95% CI 1.02, 6.04]) and verbal (HR 1.34 [0.89, 2.02]) abuse (P for trend = 0.0614), 2 or more interpersonal events (HR 1.23 [95% CI 0.87, 1.73]; P for trend = 0.2403), financial stress (HR 1.22 [95% CI 0.90, 1.64]), and caregiving 3 or more days per week (HR 1.25 [95% CI 0.87, 1.81]; P for trend = 0.2571). Results were similar, excluding women with baseline symptoms of depression or moderate-to-severe joint pain in the absence of diagnosed arthritis. CONCLUSION Our findings support the idea that diverse stressors may increase risk of developing probable RA or SLE in postmenopausal women, supporting the need for further studies in autoimmune rheumatic diseases, including childhood adverse events, life event trajectories, and modifying psychosocial and socioeconomic factors.

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.

Genome-wide DNA methylation analysis implicates enrichment of interferon pathway in African American patients with Systemic Lupus Erythematosus and European Americans with lupus nephritis.

Abstract
Systemic Lupus Erythematosus (SLE) is a chronic, multisystem, inflammatory autoimmune disease that disproportionately affects women. Trends in SLE prevalence and clinical course differ by ancestry, with those of African American ancestry presenting with more active, severe and rapidly progressive disease than European Americans. Previous research established altered epigenetic signatures in SLE patients compared to controls. However, the contribution of aberrant DNA methylation (DNAm) to the risk of SLE by ancestry and differences among patients with SLE-associated Lupus Nephritis (LN) has not been well described. We evaluated the DNA methylomes of 87 individuals including 41 SLE patients, with and without LN, and 46 controls enrolled in an ancestry diverse, well-characterized cohort study of established SLE (41 SLE patients [20 SLE-LN+, 21 SLE-LN-] and 46 sex-, race- and age-matched controls; 55% African American, 45% European American). Participants were genotyped using the Infinium Global Diversity Array (GDA), and genetic ancestry was estimated using principal components. Genome-wide DNA methylation was initially measured using the Illumina MethylationEPIC 850K Beadchip array followed by methylation-specific qPCR to validate the methylation status at putative loci. Differentially Methylated Positions (DMP) were identified using a case-control approach adjusted for ancestry. We identified a total of 51 DMPs in CpGs among SLE patients compared to controls. Genes proximal to these CpGs were highly enriched for involvement in type I interferon signaling. DMPs among European American SLE patients with LN were similar to African American SLE patients with and without LN. Our findings were validated using an orthogonal, methyl-specific PCR for three SLE-associated DMPs near or proximal to MX1, USP18, and IFITM1. Our study confirms previous reports that DMPs in CpGs associated with SLE are enriched in type I interferon genes. However, we show that European American SLE patients with LN have similar DNAm patterns to African American SLE patients irrespective of LN, suggesting that aberrant DNAm alters activity of type I interferon pathway leading to more severe disease independent of ancestry.

Abstract
Genetic deficiencies of early components of the classical complement activation pathway (especially C1q, r, s, and C4) are the strongest monogenic causal factors for the prototypic autoimmune disease systemic lupus erythematosus (SLE), but their prevalence is extremely rare. In contrast, isotype genetic deficiency of C4A and acquired deficiency of C1q by autoantibodies are frequent among patients with SLE. Here we review the genetic basis of complement deficiencies in autoimmune disease, discuss the complex genetic diversity seen in complement C4 and its association with autoimmune disease, provide guidance as to when clinicians should suspect and test for complement deficiencies, and outline the current understanding of the mechanisms relating complement deficiencies to autoimmunity. We focus primarily on SLE, as the role of complement in SLE is well-established, but will also discuss other informative diseases such as inflammatory arthritis and myositis.

Abstract
Antibody-mediated rejection (AMR) still persists as the major hurdle towards successful renal allograft survival. This paper aims to report on the HLA antibody landscape of renal transplant candidates in Malaysia. A total of 2,219 adult samples from 2016 to 2019 were analysed for anti-HLA antibodies using solid-phase assay. Our findings highlight the prevalence and risk factors for antibodies against HLA antigens in renal transplant settings, which could be beneficial for selecting compatible recipients from deceased organ donors. To the best of our knowledge, this study is the first to demonstrate that ethnic Malay and Chinese showed significantly higher prevalence of anti-HLA antibodies. Based on our multivariate analysis: (i) female gender was associated with higher risk for panel reactive antibodies (PRAs) against Class I, Class II, and Class I and II (p < 0.001); (ii) older patients (≥ 38 years old) were associated with higher risk of positivity against Class I, Class II and Class I and II (p < 0.001); (iii) Malays showed significant association with Class II antibodies (p = 0.035); Chinese patients presented with higher risk of PRA positivity against Class II (p < 0.001) and Class I and II (p = 0.01); Indians were significantly associated with higher risk of HLA antibody sensitization against Class I (p = 0.022), Class II (p = 0.026) and Class I and II (p = 0.05). Thus, our findings suggested that female gender, older age (≥ 38 years old) and ethnicity may serve as independent risk factors for HLA antibody sensitization in adult renal transplant candidates.

Ancestry-dependent genetic structure of the Xq28 risk haplotype in the Mexican population and its association with childhood-onset systemic lupus erythematosus. Front Med (Lausanne) 2023; 9:1044856. [PMID: 36714151 PMCID: PMC9877425 DOI: 10.3389/fmed.2022.1044856] [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: 09/15/2022] [Accepted: 12/27/2022] [Indexed: 01/15/2023] Open
Abstract
Objective Here we aimed to investigate the association of the Xq28 risk haplotype (H1) with susceptibility to childhood-onset systemic lupus erythematosus (SLE), and to compare its frequency and genetic structure in the Mexican population with those in other continental populations. Methods We genotyped 15 single-nucleotide variants (SNVs) that form the H1 haplotype, using TaqMan real-time PCR. The association analysis [case-control and transmission disequilibrium test (TDT)] included 376 cases and 400 adult controls, all of whom were mestizos (MEZ). To identify risk alleles in Mexican Indigenous individuals, SNVs were imputed from whole-exome sequencing data of 1,074 individuals. The allelic frequencies determined in MEZ and Indigenous individuals were compared with those of the continental populations from the 1,000 Genomes database phase 3. Linkage disequilibrium (LD) analysis of risk alleles was performed on all populations. Interleukin-1 receptor associated kinase 1 (IRAK1) and methyl CpG binding protein 2 (MECP2) mRNA levels were determined using real-time PCR. Results Case-control analysis revealed genetic association with childhood-onset SLE for all 15 SNVs (OR = 1.49-1.75; p = 0.0095 to 1.81 × 10-4) and for the Xq28 risk haplotype (OR = 1.97, p = 4 × 10-6). Comparing with individuals of European ancestry (0.14-0.16), the frequencies of the risk alleles were significantly higher in the MEZ individuals (0.55-0.68) and even higher in Indigenous individuals (0.57-0.83). LD analysis indicated a differential haplotype structure within the Indigenous groups, which was inherited to the MEZ population as a result of genetic admixture. Individuals homozygous for the Xq28 risk haplotype exhibited decreased levels of both MECP2A and B transcripts. Conclusion We found that the H1 risk haplotype differs in its conformation in the Mexican population. This difference could be attributed to positive selection within the Indigenous population, with its inheritance now having an autoimmune health impact in both the Mexican Indigenous and MEZ populations.

Abstract
Autoimmunity eventuates when the immune system attacks self-molecules as a result of the breakdown in immune tolerance. Targeting autoimmune diseases via immunomodulation has become an essential strategy in today's era. A B7 superfamily member immune checkpoint, the V-set domain containing T-cell activation inhibitor-1 (VTCN1), also known as B7-H4, B7S1, and B7x, is involved in negatively regulating T-cell activation. VTCN1 transcript has been reported in various lymphoid and non-lymphoid tissues, but its protein expression is restricted, indicating its translational regulation. Dysregulation of VTCN1 has resulted in the exacerbation of various autoimmune diseases. Moreover, increased soluble form of VTCN1 in the patient's sera positively correlates with the disease progression and severity. The current review summarizes all the reports till date, unfolding the role of VTCN1 in various autoimmune diseases and its therapeutic potential.

Abstract
Studies on clinical features of systemic lupus erythematosus among different age-onset patients are lacking in China. This multicentre study aimed to systemically compare clinical manifestations, comorbidities, organ involvement, and laboratory findings among 797 Chinese juvenile-onset, adult-onset, and late-onset SLE (JSLE, ASLE, and LSLE) patients. They were classified into JSLE, ASLE, and LSLE groups if first diagnosed at < 18, 18–50, and > 50 years old, respectively. Chi-square test and analysis of variance were employed for categorical and continuous variables respectively. In younger-onset patients, the SLE Disease Activity Index 2000 score was significantly higher (JSLE vs. ASLE vs. LSLE = 17.43 ± 9.139 vs. 16.34 ± 8.163 vs. 14.08 ± 6.474, p = 0.031). Mucocutaneous symptoms (79.5% vs. 73.4% vs. 62.0%, p = 0.042), especially malar rash (76.1% vs. 66.1% vs. 53.5%, p = 0.011) occurred more frequently, and proteinuria rate was higher (54.5% vs. 56.3% vs. 36.6%, p = 0.007). In later-onset patients, cardiopulmonary involvement increased (11.4% vs. 24.3% vs. 29.6%, p = 0.012). In ASLE, hypoalbuminemia rate elevated (46.6% vs. 59.9% vs. 47.9%, p = 0.015). Our study demonstrated in a Chinese population that JSLE may be more active and suffer mucocutaneous disorders, while LSLE tended to suffer cardiopulmonary involvement at-onset. These findings may help identify treatment priorities when facing different age-onset SLE patients.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is a chronic autoimmune disease affecting a variety of factors in the immune system. Awareness of the role of cytokines in SLE has led to new clinical perspectives in its pathogenesis; therefore, the aim of this study was to investigate the effect of vitamin 1, 25(OH) 2 D3 (D3) on the expression of IL-2, IL-4, IL-5, IL-10, and IFN-γ cytokines in patients with lupus. METHODS A total of 65 new-onset SLE patients were enrolled in the study. After peripheral blood mononuclear cell isolation, the lymphocytes of each patient were divided into two groups, one treated with a concentration of 50 μmol vitamin D3 (test) and the other untreated with vitamin D3 (control), were cultured. After 24 hours, the cultured cells were collected and the expressions of IL-2, IL-4, IL-5, IL-10, and IFN-γ genes were analyzed by RT-qPCR. RESULTS It was observed that vitamin D3 reduced expression of IFN-γ, IL-4, IL-5, and IL-10 genes by 73, 50, 37, and 29%, respectively, and increased IL-2 gene expression by 31% (p ≤ 0.05). CONCLUSION With different patterns of cytokine changes in patients with lupus in different studies, it seems that the pattern of cytokine changes is largely dependent on the phase of the disease and with this study it can be concluded that vitamin D3 administration at the time of diagnosis and in the early stages and before starting treatment have different effects from its administration in the acute stage of the disease, which requires further studies to prove. It seems that in patients with systemic lupus erythematosus, vitamin D should be administered taking into account the phase of the disease.

Abstract
Systemic lupus erythematosus is the prototypical systemic autoimmune disease, as it is characterized both by protean multi-organ system manifestations and by the uniform presence of pathogenic autoantibodies directed against components of the nucleus. Prior to the modern genetic era, the diverse clinical manifestations of SLE suggested to many that SLE patients were unlikely to share a common genetic risk basis. However, modern genetic studies have revealed that SLE usually arises when an environmental exposure occurs in an individual with a collection of genetic risk variants passing a liability threshold. Here, we summarize the current state of the field aimed at: (1) understanding the genetic architecture of this complex disease, (2) synthesizing how this genetic risk architecture impacts cellular and molecular disease pathophysiology, (3) providing illustrative examples that highlight the rich complexity of the pathobiology of this prototypical autoimmune disease and (4) communicating this complex etiopathogenesis to patients.

Systemic lupus erythematosus (SLE) is an autoimmune disease that attacks almost every organ. The condition mostly happens to adults but is also found in children, and the latter have the most severe manifestations. Among adults, females, especially non-Caucasian, are mostly affected. Even if the etiology of SLE remains unclear, studies show a close relation between this disease and both genetics and environment. Despite the large number of published articles about SLE, we still do not have a clear picture of its pathogenesis, and no specific drug has been found to treat this condition effectively. The implication of macrophages in SLE development is gaining ground, and studying it could answer these gaps. Indeed, both in vivo and in vitro studies increasingly report a strong link between this disease and macrophages. Hence, this review aims to explore the role of macrophages polarization and plasticity in SLE development. Understanding this role is of paramount importance because in-depth knowledge of the connection between macrophages and this systemic disease could clarify its pathogenesis and provide a foundation for macrophage-centered therapeutic approaches.

Abstract
BACKGROUND Patients with chronic diseases are potential candidates for inadequate follow-up of drug therapy, tending to incur damage to the intended results. This deserves greater attention in the pandemic period, as they are in the considered risk group. METHODS We aim to assess Treatment Adherence Measure and analyze associations with characteristics related to the patient, treatment, disease, health professionals and service, and sociodemographic issues in patients with Systemic Lupus Erythematosus (SLE). W conducted a cross-sectional study with a sample of 116 participants, whose data were collected through individual interviews and review of medical records, during the first months of the COVID-19 pandemic in Brazil. Adherence was measured using the Treatment Adherence Measure, and associations were evidenced through described and inferential statistics. RESULTS The percentage of adherent patients was 55.2%. An association was found between MTA (Medication Treatment Adherence) and physical exercise practice (p = 0.032), and difficulties with treatment (p = 0.002). Conclusion: Participants who did not practice physical exercise were 3.71 times more likely to not adhere to the treatment. Individuals who identified difficulties in the treatment were 3.43 times more likely to not adhere to the treatment; we believe that the pandemic may have influenced this result. More targeted studies are needed to measure the impact on MTA in these patients.

Abstract
The United States has a deficit of rheumatology specialists. This leads to an increased burden in accessing care for patients requiring specialized care. Given that most rheumatologists are located in urban centers at large hospitals, many lupus patients must travel long distances for routine appointments. The present work aims to determine whether travel burden is associated with increased levels of depression and anxiety among these patients. Data for this study were collected from baseline visits of patients participating in a lupus study at MUSC. A travel/economic burden survey was assessed as well as the 8-item Patient Health Questionnaire (PHQ-8) and the 7-item Generalized Anxiety Disorder (GAD-7) survey as measures of depression and anxiety, respectively. Linear regression models were used to assess the relationship between travel burden and depression and anxiety. Frequency of healthcare visits was significantly associated with increased depression (β = 1.3, p = 0.02). Significant relationships were identified between anxiety and requiring time off from work for healthcare appointments (β = 4, p = 0.02), and anxiety and perceived difficulty in traveling to primary care providers (β = 3.1, p = 0.04). Results from this study provide evidence that travel burden can have an effect on lupus patients' anxiety and depression levels.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) or lupus is an autoimmune disorder whose cause and reason for disproportionate impact on minorities remains enigmatic. Furthermore, statistics describing lupus incidence and prevalence are outdated and often based on small samples. To begin to address this disparity this report describes preliminary data to be utilized in the development of a state-wide lupus registry in South Carolina. METHODS A prospective survey and retrospective data from the South Carolina Budget and Control Board Office of Research & Statistics were used to capture data pertaining to knowledge of lupus, prevalence, and access to lupus care. RESULTS Retrospective ORS data indicated there were 11,690 individuals living with lupus in 2014 with the average direct cost of $69,999.40 in medical care. Prospective surveys (N = 325), in over 16 locations in South Carolina, showed 31% knew someone with lupus, 16% had been diagnosed with lupus, and 50% did not know of a medical facility that treated lupus. CONCLUSION A lupus registry and repository will provide ongoing access for researchers on the impact of lupus on communities in South Carolina. Lupus is highly prevalent, but disproportionately represented in terms of patient information and participation in clinical trials, so it is also expected that this preliminary work will provide an ongoing process in which the medical community can better engage lupus patients.

Abstract
OBJECTIVES Previous studies have reported inconsistent results on the relationship between alcohol intake and the risk of systemic lupus erythematosus (SLE). Therefore, we conducted a systematic review and meta-analysis to illustrate the potential role of alcohol intake on the progression of SLE. METHODS An electronic search of the PubMed, EmBase, and the Cochrane library databases was conducted from their inception up to March 2020. Observational studies that investigated the role of alcohol intake on the risk of SLE were eligible for inclusion in this study. The pooled odds ratio (OR) with 95% confidence interval (CI) was calculated as an effect estimate using the random-effects model. RESULTS Seven case-control studies (n = 3, 251) and three cohort studies (n = 322, 479) were selected for the final meta-analysis. Mild (OR: 0.85; 95% CI: 0.53-1.38; p = 0.515) or heavy (OR: 0.63; 95% CI: 0.37-1.09; p = 0.102) alcohol intake were not associated with the risk of SLE, while moderate alcohol intake could protect against the risk of SLE (OR: 0.71; 95% CI: 0.55-0.93; p = 0.012). Sensitivity analysis suggested that heavy alcohol intake was associated with a reduced risk of SLE (OR: 0.47; 95% CI: 0.32-0.67; p < 0.001). CONCLUSIONS This study found that moderate alcohol intake could protect against the risk of SLE, while mild or heavy alcohol intake did not significantly affect the risk of SLE.

Abstract
Objectives
This study aims to explore the perceptions, concerns, expectations, and viewpoints of female patients with systemic lupus erythematosus (SLE) regarding reproductive health in Iran. Patients and methods
This qualitative research was conducted using 27 semi-structured deep interviews with 19 married female patients (mean age 37.4±7.0 years; range, 15 to 49 years) suffering from SLE selected through purposive sampling in the Rheumatology Center of Shariati Hospital, Tehran, Iran between August 2017 and March 2018. Results
Patients’ perceptions were classified into six categories and 14 subcategories: physical suffering (debilitating pain, gradual disability, and apparent transformation), psychological stress (family disturbance and sexual dissatisfaction), challenging fertility (bothersome pregnancy and impaired parenting), adaptation to the disease (self-care and lifestyle modification), need for a supporter (support from the spouse, support from the family and acquaintances, and lack of occupational and social support), and spirituality (forgiveness of sins and resorting to God). Conclusion The findings clearly suggested the negative effects of SLE on the reproductive health of these patients. This study emphasized the importance of care and support for female patients with SLE. We hope that this research enhances the awareness of care providers about physical, sexual, psychological, social, and spiritual factors, since taking care of these patients requires strategic and multidisciplinary management.

Abstract
OBJECTIVES Early detection of autoimmune rheumatic diseases is crucial given their high morbidity and mortality and short window of opportunity to improve patient outcomes. Self-administered screening questionnaires such as the connective tissue disease screening questionnaire (CSQ) have been shown to promote early detection of autoimmune rheumatic diseases. However, optimal scoring of screening questionnaires may differ with prevalence of clinical features and changes in classification criteria. We compared the performance of 3 scoring methods for the CSQ for early detection of autoimmune rheumatic diseases in a multi-ethnic Asian population. METHODS Patients who were newly referred for evaluation of possible autoimmune rheumatic diseases were invited to answer the cross-culturally adapted CSQ. Detection of autoimmune rheumatic diseases using 1) the original CSQ scoring, 2) a modified CSQ scoring and 3) a scoring based on current classification criteria, were compared to classification of autoimmune rheumatic diseases by classification criteria. RESULTS Of 819 participants, 85 were classified as having autoimmune rheumatic diseases screened for by the adapted CSQ. The original CSQ scoring yielded relatively lower sensitivities in detecting both any and individual autoimmune rheumatic diseases (67% and 20-57%, respectively) compared to the modified CSQ scoring (81% and 60-73%, respectively) and the scoring based on current classification criteria (89% and 50-88%, respectively). CONCLUSION The adapted CSQ with the classification criteria-based scoring achieved relatively high sensitivities in detecting autoimmune rheumatic diseases, suggesting this could be employed as the first step in population screening.

Abstract
Severe acute respiratory syndrome coronavirus (SARS-CoV-2), the virus causing Coronavirus disease 2019 (COVID-19), has had a huge impact on health services with a high mortality associated with complications including pneumonia and acute respiratory distress syndrome. Historical evidence suggests that Lupus patients have a higher incidence of several viral infections. This is likely due to a combination of immune dysfunction, immunosuppressive therapy and excess co-morbidities. In this context there has been concern that Lupus patients may be at a higher risk of developing COVID-19 and suffering a severe disease course. As a result, many Lupus patients have been advised to ‘shield’ by isolating from social contact in the hope that this will reduce the likelihood of infection. Early clinical data does not appear to show that the incidence of COVID-19 is higher in Lupus patients. Reassuringly, the clinical course of COVID-19 in Lupus does not generally seem to be more severe than in the general population. There has been huge interest in repurposing existing drugs as potential treatments, including several used to treat Lupus. Of these, corticosteroids and hydroxychloroquine are the most well researched so far. The current evidence suggests that the corticosteroid dexamethasone improves outcome for the sickest COVID-19 patients requiring respiratory support. Initial reports suggested that hydroxychloroquine could have a positive impact on the course of COVID-19, however larger prospective studies have not supported this. Janus kinase inhibitors, currently being investigated for efficacy in lupus, have been shown to have anti-viral effects in vitro and inhibiting the JAK-STAT pathway may dampen down the host hyper-inflammatory response. Several trials are ongoing to assess the outcome of the use of JAK inhibitors in COVID-19 positive patients. For most patients continuing with their existing therapies to prevent a lupus flare or adverse events associated with sudden corticosteroid withdrawal is important whilst an Individualised risk assessment remains vital.

Abstract
Systemic lupus erythematosus (SLE) is a protypical autoimmune disease and genetic factors play important roles in its pathogenesis. Since present SLE susceptibility loci are mainly studied through meta-analysis of genome-wide association study, we performed promoter activity analysis to examine the biological functions of SLE-associated single-nucleotide polymorphisms (SNPs). We found at SNP positions rs1341239, rs1800795, rs1800796, rs1800872, rs1800871, rs187238, rs360719, rs8178822, rs3761549, different alleles influenced respective promoter activities in different manners, and the effects also appeared under glucocorticoid treatment. In addition, some SNPs showed strong correlations with levels of respective serum factors, but in most cases the associations were only demonstrated in SLE individuals. Our study has further disclose the functional roles of SLE-associate SNPs in SLE pathogenesis.

Abstract
Single-nucleotide polymorphisms (SNPs) in the UHRF gene have been shown to be associated with systemic lupus erythematosus (SLE) in European and Hong Kong Chinese, but statistically significant evidence for association has not been found in a mainland Han Chinese population. Therefore, we selected SNP rs13205210 located in UHRF1BP1 as a candidate association from our previously published genome-wide association study (GWAS) data of SLE (1,047 cases and 1,205 controls from a mainland Han Chinese population) to explore the association between the UHRF1BP1 gene and SLE. We conducted a large-scale replication study in an additional independent sample of 3,509 cases and 8,246 controls from a mainland Han Chinese population. Real-time PCR was used to determine gene expression differences in peripheral blood mononuclear cells (PBMCs) from cases and controls. As a result, we replicated the association between the UHRF1BP1 gene and SLE (rs13205210, missense, Pmeta = 2.26E-17, odds ratio = 1.41) by a meta-analysis of our previous GWAS and this replication study involving a total of 4,556 cases and 9,451 controls. The UHRF1BP1 mRNA expression level in PBMCs was significantly decreased in patients with SLE compared with that in healthy controls. SNP rs13205210 exhibited an expression quantitative trait loci effect on the UHRF1BP1 gene in PBMCs from patients. In conclusion, this study not only suggests that the UHRF1BP1 gene was associated with SLE in a mainland Han Chinese population, but also implied that it might be a common genetic factor contributing to SLE susceptibility in multiple populations.

Abstract
INTRODUCTION Over 400,000 slaves were taken from Africa and brought to Charleston, South Carolina, as part of the transatlantic slave trade during the 18th and 19th centuries. Due to these negative historical events, the healthcare of African Americans in Charleston may be compromised in regard to chronic illnesses and other conditions affecting minorities, such as lupus. MATERIALS AND METHODS The current study used an ethnographic approach to obtain the perspectives of lupus patients with the goal of identifying gaps within current research. In addition to patient perspectives, the geographical location of Charleston, South Carolina was considered through inquiries around culture, community, advocacy, and client/patient interaction to establish a narrative for the themes that emerged. RESULTS The eleven major themes identified were connectedness, knowledge, experience with lupus, compliance, clinical trial participation, career and planning for the future, visits, access to resources, lifestyle, transition from child to adult care, and an overarching theme of self-management. CONCLUSION Understanding healthcare perceptions and decision-making among culturally diverse populations, particularly those who have been defined by centuries of substandard care, marginalization, exploitation, and distrust, is critical to the development of culturally tailored interventions designed to improve patient outcomes and reduce health disparities.

Abstract
INTRODUCTION Systemic lupus erythematosus affects 4.8-78.5 people per 100,000 worldwide, 90% of whom are females. Geography and ethnicity have been shown to significantly affect the prevalence and natural history of the disease. Lupus nephritis affects around half of patients with systemic lupus erythematosus. Data about systemic lupus erythematosus and lupus nephritis in the Middle East are still scarce. In this study, we aimed to describe the characteristics of systemic lupus erythematosus and lupus nephritis at a tertiary care center in Lebanon. METHODS This is a retrospective chart review of all biopsy-proven lupus nephritis patients admitted to the American University of Beirut medical center between January 2000 and December 2018. Patients above 12 years of age who had any International Society of Nephrology/Renal Pathology Society (ISN/RPS) class of lupus nephritis on their renal biopsy were included in the study. RESULTS The study included 55 patients with lupus nephritis. Upon presentation of systemic lupus erythematosus, the most common clinical feature was arthritis, seen in 83% of patients, followed by anemia (82%) and malar rash (48%). In total 93% had positive ANA, 89% had positive anti-dsDNA and 98% of patients had proteinuria. The most common ISN/RPS class of lupus nephritis in our series was IV (49%). At the time of the biopsy 15% of patients underwent dialysis. At 6 months, 11/27 had complete remission, 6/27 had partial remission and 10/27 had no remission. At 1 year, 8/23 had complete remission, 4/23 had partial remission and 11/23 had no remission. During the study period, 15 out of 35 patients available for analysis had chronic kidney disease (CKD) and six out of 34 patients developed end-stage kidney disease requiring renal replacement therapy. In comparison to other series in the region, our series had more males affected, higher creatinine at the time of biopsy and greater degree of proteinuria. CONCLUSION Our study provided insight on the demographics, characteristics, and outcomes of lupus nephritis in Lebanon. Interestingly, male gender was present in a quarter of patients. This warrants further investigation and confirmation. We are hoping to expand this experience into a national prospective registry to further characterize this entity in our region.

Peer approaches to self-management (PALS): comparing a peer mentoring approach for disease self-management in African American women with lupus with a social support control: study protocol for a randomized controlled trial. Trials 2019; 20:529.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE or lupus) is a chronic autoimmune disease that is associated with increased morbidity, mortality, healthcare costs and decreased quality of life. African Americans in the USA have three to four times greater prevalence of SLE, risk of developing SLE at an earlier age, and SLE-related disease activity, damage, and mortality compared with Caucasians, with the highest rates experienced by African American women. There is strong evidence that patient-level factors are associated with outcomes, which justifies targeting them with intervention. While evidence-based self-management interventions that incorporate both social support and health education have reduced pain, improved function, and delayed disability among patients with SLE, African Americans and women are still disproportionately impacted by SLE. Peer mentoring interventions are effective in other chronic conditions that disproportionately affect minorities, such as diabetes mellitus, HIV, and kidney disease, but there is currently no empirically tested peer mentoring intervention developed for patients with SLE. Preliminary data from our group suggest that peer mentoring improves self-management, reduces disease activity, and improves health-related quality of life (HRQOL) in African American women with SLE. METHODS This study will test an innovative, manualized peer mentorship program designed to provide modeling and reinforcement by peers (mentors) to other African American women with SLE (mentees) to encourage them to engage in activities that promote disease self-management. Through a randomized, "mentored" or "support group" controlled design, we will assess the efficacy and mechanism(s) of this intervention in self-management, disease activity, and HRQOL. DISCUSSION This is the first study to test peer mentorship as an alternative strategy to improve outcomes in African American women with SLE. This could result in a model for other programs that aim to improve disease self-management, disease activity, and HRQOL in African American women suffering from chronic illness. The peer mentoring approach is uniquely fitted to African Americans, and this intervention has the potential to lead to health improvements for African American women with SLE that have not been attainable with other interventions. This would significantly reduce disparities and have considerable public health impact. TRIAL REGISTRATION ClinicalTrials.gov, NCT03734055 . Registered on 27 November 2018.

Catalytically Impaired TYK2 Variants are Protective Against Childhood- and Adult-Onset Systemic Lupus Erythematosus in Mexicans. Sci Rep 2019; 9:12165. [PMID: 31434951 PMCID: PMC6704113 DOI: 10.1038/s41598-019-48451-3] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2018] [Accepted: 08/06/2019] [Indexed: 01/30/2023] Open
Abstract
Type I interferon (IFN-I) pathway plays a central role in the systemic lupus erythematosus (SLE) pathogenesis. Recent data suggest that SLE is associated with variants in IFN-I genes, such as tyrosine kinase 2 (TYK2), which is crucial in anti-viral immunity. Here, five TYK2 single nucleotide polymorphisms (SNPs) were genotyped in 368 childhood-onset SLE Mexican patients and 516 sex-matched healthy controls. Allele frequencies were also estimated in four indigenous groups. SLE protection was associated with TYK2 risk infection variants affecting residually its catalytic domain, rs12720356 (OR = 0.308; p = 0.041) and rs34536443 (OR = 0.370; p = 0.034), but not with rs2304256, rs12720270, and rs280500. This association was replicated in a 506 adult-onset SLE patients sample (OR = 0.250; p = 0.005, and OR = 0.277; p = 0.008, respectively). The minor alleles of both associated SNPs had a lower frequency in Mestizos than in Spaniards and were absent or rare in indigenous, suggesting that the presence of these alleles in the Mexican Mestizo population was derived from the Spaniards. For the first time, we report genetic variants with a protective effect in childhood- and adult-onset SLE Mexican population. Our results suggest that the frequency of IFN-I alleles associated with SLE, may have been shaped in populations exposed to infectious diseases for long periods, and this could be an explanation why Native American ancestry is associated with a higher SLE prevalence and an earlier onset.

Abstract
BACKGROUND Female patients with systemic lupus erythematosus (SLE) are prone to have musculoskeletal system involvement, which could lead to joint damage. However, few studies have assessed the incidence of arthroplasty in female patients with SLE. The aim of this study was to investigate the risk of total hip replacement surgery and total knee replacement surgery in patients with SLE. METHODS We identified 577 female patients with newly diagnosed SLE between 2000 and 2012 using the Taiwan's National Health Insurance Research Database. A comparison cohort was constructed with female patients without SLE in a ratio of 5:1, based on frequency matching for 10-year age interval, and index year, for each patient with SLE. Both cohorts were followed until a diagnosis of the study outcomes or the end of the follow-up period. RESULTS Female patients with SLE showed a significantly higher incidence of receiving total hip replacement surgery (adjusted incidence rate ratio [aIRR] 6.47; P < 0.001), but not total knee replacement surgery (aIRR 1.81; P = 0.227). Moreover, age-group stratified analyses indicated a high incidence for receiving total hip replacement surgery among young female patients with SLE (aIRR 7.70; P = 0.001). CONCLUSION Young female patients with SLE had a high risk of receiving total hip replacement surgery, but not total knee replacement surgery.

Abstract
Most sickle cell disease (SCD) patients rely on blood transfusion as their main treatment strategy. However, frequent blood transfusion poses the risk of alloimmunization. On average, 30% of SCD patients will alloimmunize while other patient groups form antibodies less frequently. Identification of genetic markers may help to predict which patients are at risk to form alloantibodies. The aim of this study was to evaluate whether genetic variations in the Toll-like receptor pathway or in genes previously associated with antibody-mediated conditions are associated with red blood cell (RBC) alloimmunization in a cohort of SCD patients. In this case-control study, cases had a documented history of alloimmunization while controls had received ≥20 RBC units without alloantibody formation. We used a customized single nucleotide polymorphism (SNP) panel to genotype 690 SNPs in 275 (130 controls, 145 cases) patients. Frequencies were compared using multiple logistic regression analysis. In our primary analysis, no SNPs were found to be significantly associated with alloimmunization after correction for multiple testing. However, in a secondary analysis with a less stringent threshold for significance we found 19 moderately associated SNPs. Among others, SNPs in TLR1/TANK and MALT1 were associated with a higher alloimmunization risk, while SNPs in STAM/IFNAR1 and STAT4 conferred a lower alloimmunization risk.

Abstract
Objectives The aim of this study was to investigate the influence of age at disease onset on disease expression and outcomes of pediatric systemic lupus erythematosus SLE (pSLE). Methods A total of 103 patients with pSLE from Sultan Qaboos University Hospital, Oman, were retrospectively studied. Epidemiological, clinical phenotype, disease severity, serology, treatment, and outcome were compared among the three groups using univariate statistical tests. Results The mean disease duration of the cohort was 9.8 ± 4.7 years. The patients were divided into three groups: prepubertal onset (n=39) with mean age at diagnosis of 5.1 ± 2.0 years and pubertal disease onset (n=29) with mean age at diagnosis of 10.8 ± 1.0 years as well as postpubertal disease onset (n=35) group with mean age at diagnosis of 15.3 ± 1.6 years. The prepubertal pSLE cohort demonstrates unique characteristics with increased frequency of familial SLE (61%) of which 49% were from first-degree relatives. Similarly, this group had distinctive clinical features, which included increased renal disease in pubertal and postpubertal groups, respectively (51% vs 23% vs 20%; p=0.039). Prepubertal, similar to pubertal group, had a higher incidence of cutaneous manifestations than in the postpubertal group (74% vs 69% vs 46%; p=0.029). Laboratory features in prepubertal group were distinct with increased frequency of positive anti-cardiolipin antibodies (47%), anti-glycoprotein antibodies (42%), ANCA (62%), and low complement levels (97%) compared to pubertal and postpubertal group. The prepubertal group also has the lowest frequency of positive SSA antibodies (18%) and SSB antibodies (5.1%). The overall mean SLEDAI score in pSLE cohort was 15.6 ± 18.5. The mean SLEDAI scores among the groups showed no significance difference (p=0.110). The overall SLICC DI ≥1 was 36% with a mean damage score of 0.76 ± 1.38. No significant differences in damage index (SLICC DI ≥1) were noted among the groups. Conclusions Distinct clinical features were identified in prepubertal onset pSLE population of Arab ethnicity. Given the high rate of consanguineous marriage and high frequency of familial SLE in this cohort, these manifestations could be explained by higher frequency of genetic factors that influence the disease pathogenesis.

Abstract
Aims This study is aimed at exploring the relation between IL-33 single-nucleotide polymorphisms (SNPs) and the risk of systemic lupus erythematosus (SLE). Methods SNPStats (online software) was used to test the Hardy-Weinberg equilibrium in controls. Generalized multifactor dimensionality reduction (GMDR) was adopted to screen the preferable interaction between IL-33 SNPs and current smoking. Results Logistic regression analysis based on the fundamental data of age, gender, BMI, current smoking, and alcohol drinking showed that both rs1929992-G and rs1891385-C alleles were correlated with an increasing risk of SLE, the ORs (95% CI) of which were 1.62 (1.21-2.05) and 1.64 (1.22-2.10), respectively. One two-locus model (rs1929992×current smoking) had a testing accuracy of 60.11% (P = 0.0010). Through an overall multidimensional model, optimum cross-validation consistency was obtained. The analysis indicated that current smoking status influenced the SLE risk depending on the genotypes at rs1929992. Pairwise LD analysis indicated that haplotype rs1929992G-rs7044343T was statistically related to the elevating risk of SLE (P < 0.05). Those subjects with the G-T haplotype had a higher SLE risk than those with other haplotypes, after correction with factors, including gender, alcohol drinking, age, BMI, and current smoking. Conclusions The rs1929992-G and rs1891385-C allele, interaction between the rs1929992 gene and current smoking, and haplotype rs1929992G-rs7044343T were all risk factors of SLE.

Material and methods In this cross-sectional study, 340 women (170 with SLE and 170 healthy) aged 18–49 years were investigated. Convenience sampling was used to select the participants. In this study, a demographic questionnaire, the Depression, Anxiety, and Stress Scales – 21 Items (DASS-21), and the Female Sexual Function Index (FSFI) were applied. Data were analyzed with SPSS 16 using Spearman’s correlation, χ2, Mann-Whitney, covariance, and multiple regression statistics; p-values less than 0.05 were considered significant. Results The results showed a significant difference in sexual function between the SLE and healthy groups. According to covariance analysis, the difference remained significant after controlling for confounding factors (stress, depression, anxiety). Moreover, the effect of SLE on the sexual function had a significant correlation with age, life status, number and age of children, economic status, menstruation, duration of marriage, age at diagnosis, disease duration and activity, stress, anxiety, and depression. The results of multiple regression analysis showed that age, disease activity, depression, and life status had the highest correlation with sexual dysfunction in women with SLE. Conclusions The results of this study indicated that more attention should be paid to the sexual health of women suffering from SLE as a neglected aspect of their treatment, which requires an interdisciplinary approach to shift the care of these patients from a biomedical model to a biopsychosocial model.

[PMID: 30805629 DOI: 10.1093/rheumatology/kez006] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2018] [Revised: 12/03/2018] [Indexed: 11/14/2022] Open
Abstract
OBJECTIVE Childhood-onset SLE (cSLE) manifests differently than adult-onset SLE (aSLE). This study determined whether ethnic differences contribute to the differences in clinical presentation between the two groups. METHODS This cross-sectional study used data from a multi-centred registry from eight adult and four paediatric Canadian centres gathered at study entry. We compared the frequency of clinical manifestations and autoantibodies between aSLE and cSLE. For those with a significant difference, a multivariable logistic regression was performed, adjusting for ethnicity, SLE onset (cSLE vs aSLE), disease duration and centre. Disease activity and damage between aSLE and cSLE were compared after stratifying by disease duration. RESULTS Of 552 aSLE subjects, 502 (90.9%) were female and 381 (69.0%) were Caucasian. Mean age at diagnosis was 37.0 ± 13.6 years and disease duration 10.9 ± 9.6 years. Of 276 cSLE subjects, 231 (83.7%) were female and 101 (36.6%) were Caucasian. Mean age at diagnosis was 12.7 ± 3.3 years and disease duration 5.6 ± 8.2 years. In multivariable regression analysis, aSLE was associated with decreased odds of having a neurologic disorder (odds ratio = 0.49) and increased odds of having aCL antibodies (odds ratio = 1.85). Disease activity and damage accrual scores were higher in aSLE than cSLE within the same disease duration strata, although the differences were not clinically significant. Ethnicity was not associated with any differences in clinical manifestations or autoantibody frequency between aSLE and cSLE. CONCLUSIONS Although a crude comparison of aSLE and cSLE yielded several differences in clinical symptoms and autoantibodies, this difference was not attributable to ethnic differences between aSLE and cSLE.

Abstract
AIM Pulmonary arterial hypertension (PAH) is a complex and devastating complication of systemic lupus erythematosus (SLE). We sought to describe the baseline characteristics of right heart catheterization (RHC)-confirmed SLE-associated PAH and identify risk factors for PAH in SLE patients. METHODS A multicenter, cross-sectional study was conducted using the Chinese SLE Treatment and Research group (CSTAR) registry. Baseline data for patients with SLE-associated PAH and SLE patients without PAH were collected and compared. Risk factors for PAH among patients with SLE were identified. RESULTS A total of 292 patients with SLE-associated PAH were enrolled. RHC was used to reveal hemodynamic features, including mean pulmonary arterial pressure (46.2 ± 12.0 mm Hg), pulmonary arterial wedge pressure (7.84 ± 3.92 mm Hg), pulmonary vascular resistance (10.86 ± 5.57 Wood units), and cardiac index (2.77 ± 0.91 L/min × m2 ). A multivariate logistic regression analysis showed that serositis (odds ratio [OR] = 5.524, 95% CI 3.605-8.465, P < 0.001), anti-ribonucleoprotein (RNP) antibody positivity (OR = 13.332, 95% CI 9.500-18.710, P < 0.001), and diffusion capacity of carbon monoxide in the lung (DLCO)/%Pred <70% (OR = 10.018, 95% CI 6.619-15.162, P < 0.001) were independent predictors of PAH. We recommend using transthoracic echocardiography (TTE) to perform early screening of SLE patients who have serositis, anti-RNP antibody positivity, or DLCO/%Pred <70%. RHC is suggested for patients suspected of having PAH. Once a diagnosis of SLE-PAH is confirmed, evaluation and treatment should immediately begin. CONCLUSION Overall, we recommend performing early screening using TTE in SLE patients with serositis, anti-RNP antibodies, or a DLCO/%Pred <70%, even for patients in a relatively stable condition according to SLE disease activity index.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease associated with widespread inflammation and tissue damage. It is more common and severe among Blacks, Hispanics, and Asians; with higher incidence in women. While the goals of medical treatment are to prevent flares and reduce organ damage, up to 50% of patients perceive their health to be suboptimal with unaddressed needs including fatigue and pain. Recent SLE treatment guidelines focus on improving quality of life. Yoga has shown improvements in quality-of-life and fatigue in various diagnoses. While there is growing evidence that yoga therapy may help osteoarthritis and rheumatoid arthritis symptoms, there is only one reference in the literature related to SLE. METHODS/SETTING An adjunct study was undertaken to evaluate adapting the Yoga as Self Care for Arthritis in Minority Communities study for a bilingual population living with SLE in the Washington, DC area. Informants included 7 patients enrolled onto the study, and 3 yoga instructors living with SLE. Qualitative methods included journals and semi-structured interviews. RESULTS Enrolling patients clarified revisions for intake questionnaires, and symptoms that may impact class participation. Participants demonstrated increased balance, body awareness, and tolerated a faster-paced yoga class when compared to those in the parent study. Yoga instructors' recommendations included modifying yoga based on energy levels and frequent changes in physical ability. CONCLUSION This paper shares perspectives from various informants and affirms the feasibility of progressing to a larger study. It summarizes our findings and recommendations towards creating a randomized controlled trial, as there are currently none in the literature.

Abstract
Background The autoimmune disease systemic lupus erythematosus (SLE) occurs more frequently in patients of African descent with high morbidity and mortality. Current SLE diagnostic criteria including antinuclear antibody (ANA) reactivity are derived largely from non-African populations. This study characterises ANA reactivity patterns and relates them to SLE clinical presentation in Black African patients. Methods Sera from Black participants (61 patients with SLE and 100 controls) aged 1-81 years were analysed for reactivity against the antigens: uridine 1-ribonuclear protein, Smith uridine-1-5 ribonuclear protein antigen, soluble substance-A, recombinant Ro-52, soluble substance-B, Scl-70, cytoplasmic histidyl-tRNA synthetase antigen, proliferating cell nuclear antigen (PCNA), nucleosomes, ribonuclear P-protein, antimitochondrial antibody M2 (AMA-M2), histones, double-stranded DNA (dsDNA), centromere protein B and polymyositis-sclerosis overlap antigen. Findings A significantly higher proportion (97%) of the 61 patients with SLE had detectable autoantibody reactivity compared with 15% of the 100 controls (p<0.001). The highest frequencies of autoantibody reactivity in patients with SLE were against the dsDNA antigen (41%) and PCNA (54%). Anti-PCNA and anti-dsDNA reactivity were mutually exclusive (p<0.001) giving rise to two distinct groups of Black African patients with SLE. The first group (n=25) had reactivity profiles consistent with international standard SLE definitions, including anti-dsDNA reactivity, and was 13 times more likely to present with joint symptoms. The larger, second group (n=34), characterised by anti-PCNA and anti-AMA-M2 reactivity, was nine times more likely to present with only cutaneous symptoms. Interpretation Our study demonstrates a need to extend autoantibody panels to include anti-PCNA in the diagnostic process of Black African patients and further refine the predictive values of the reactivity to different antigens to differentiate SLE syndromes in African populations.

Abstract
AIM To investigate secular trends and regional disparities in hospitalizations due to systemic connective tissue diseases (SCTD) in Sweden from 1998 to 2016. METHOD We identified all hospital admissions with a principal diagnosis of SCTD (ICD-10 codes: M30-M36) from the Swedish National Patient Register. Joinpoint regression was used to assess secular trends in age-standardized hospitalization rates (ASHR) and proportions of SCTD from all and musculoskeletal disorders hospitalizations. We also assessed the secular trends in the absolute and relative regional disparities of SCTD hospitalizations. RESULTS We identified 89 333 SCTD hospitalizations (0.3% of all hospitalizations), of these about 69% were for women and 49% of patients were aged 15-64 years. Polyarteritis nodosa and related conditions (PANRC) and systemic lupus erythematosus (SLE) were the most frequent SCTD among those aged <10 years and 10-54 years, respectively. Joinpoint regression suggested that both rates and proportions of SCTD hospitalizations declined over time. These trends persisted among sex, age and diagnosis subgroups except for PANRC in patients aged 0-19 years who observed an average annual increase of 3.4% (95% CI: 1.8, 5.1) over the study period. There were 2.4-fold (95% CI: 2.3-2.5) difference between the regions with the highest and lowest mean ASHR. There was no statistically significant secular trend in the relative regional disparities, whereas the absolute regional disparity declined over time. CONCLUSION There were substantial decreases in the absolute and relative burden of SCTD hospitalizations reflecting possible improvements in disease management in Sweden. The rising trend in PANRC among the youngest children warrants further investigation.

Abstract
To investigate the clinical significance of the ratio of T helper cell 17 (Th17) cells to single immunoglobulin IL-1-related receptor (SIGIRR)+ cluster of differentiation (CD4)+ T cells in patients with systemic lupus erythematosus (SLE), novel data and data from previous studies were analyzed. The frequency of Th17 cells in peripheral blood mononuclear cells (PBMCs) and their correlation with clinical data were evaluated in 48 patients with SLE and 38 healthy controls through flow cytometry. Compared with healthy controls, the percentage of Th17 cells was significantly increased in the PBMCs of patients with SLE (Z=-5.82, P<0.001). Compared with inactive SLE (ISLE), the percentage of Th17 cells in active SLE (ASLE) were significantly increased (Z=-4.26, P<0.0001). Compared with patients without lupus nephritis, the frequency of Th17 cells was significant increased (Z=-2.20, P=0.028). The frequency of Th17 cells was inversely correlated with the frequency of SIGIRR+CD4+ T cells (r=-0.61, P<0.001). The ratio of Th17 cells to SIGIRR+CD4+ T cells in ASLE was significantly increased compared with healthy controls or patients with ISLE (P<0.001) and was inversely correlated with complement component 3 and complement component 4, and positively correlated with SLE disease activity index and 24-h proteinuria (P<0.05). In summary, increased numbers of Th17 cells and decreased numbers of SIGIRR+CD4+ T cells in patients with SLE suggested that SIGIRR+CD4+ T and Th17 cells may be involved in the pathogenesis of SLE.

Abstract
Systemic Lupus Erythematosus (SLE) is a complex chronic autoimmune disease that manifests a wide range of organ involvement. Traditionally, the diagnosis and management of SLE is provided at secondary and tertiary centers to ensure prompt initiation of treatment, adequate control of flares and prevention of irreversible organ damage. Notwithstanding, the role of primary care in SLE is also emerging as there are still significant unmet needs such as the diagnostic delay at the community level and the high burden of therapy- and disease-related comorbidities. In the present review, we summarize practical messages for primary care physicians and general practitioners (GPs) concerning early diagnosis and proper referral of patients with SLE. In addition, we discuss the main comorbidities complicating the disease course and the recommended preventative measures, and we also provide an update on the role and current educational needs of GPs regarding the disease.

Abstract
OBJECTIVE To examine the feasibility and potential benefits of peer mentoring to improve the disease self-management and quality of life of individuals with systemic lupus erythematosus (SLE). METHODS Peer mentors were trained and paired with up to 3 mentees to receive self-management education and support by telephone over 12 weeks. This study took place at an academic teaching hospital in Charleston, South Carolina. Seven quads consisting of 1 peer mentor and 3 mentees were matched, based on factors such as age, area of residence, and marital and work status. Mentee outcomes of self-management, health-related quality of life, and disease activity were measured using validated tools at baseline, mid-intervention, and post-intervention. Descriptive statistics and effect sizes were calculated to determine clinically important (>0.3) changes from baseline. RESULTS Mentees showed trends toward lower disease activity (P = 0.004) and improved health-related quality of life, in the form of decreased anxiety (P = 0.018) and decreased depression (P = 0.057). Other improvements in health-related quality of life were observed with effect sizes >0.3, but did not reach statistical significance. In addition, both mentees and mentors gave very high scores for perceived treatment credibility and service delivery. CONCLUSION The intervention was well received. Training, the peer-mentoring program, and outcome measures were demonstrated to be feasible with modifications. This result provides preliminary support for the efficacy, acceptability, and perceived credibility of a peer-mentoring approach to improve disease self-management and health-related quality of life in African American women with SLE. Peer mentoring may augment current rheumatologic care.

Abstract
The population of people with immunodeficiency is increasing due to the accelerating pace of life, increase in work pressure, and lack of exercise, irregularity of diet and rest, and problems of environmental pollution. Chinese herbal medicines have been shown to improve immunity, with little to no side effects. In recent years, studies have shown that Shcisandrol A (Sch A) regulates immune functioning and inhibits inflammation of the nervous system. The current study used gene expression profiling of spleen tissue to screen differentially expressed genes related to Sch A treatment on cyclophosphamide (Cy)-induced immunosuppressed mice. The differentially expressed gene-related pathways were analyzed by gene ontology function cluster analysis and qPCR. Five genes related to immune functioning were found to be regulated by Sch A treatment: Mapk3, Pik3r1, Pik3r5, Ikbkg, and Cd247. qPCR analysis showed that all five genes were significantly down-regulated in mice treated with Sch A compared to untreated immunosuppressed mice. These results suggest potential mechanisms through which Sch A regulates immune functioning.

Atherosclerotic Heart Disease in Women With Autoimmune Rheumatologic Inflammatory Conditions. Can J Cardiol 2018; 34:381-389.

Abstract
Women have a higher prevalence of several inflammatory rheumatologic conditions. These include systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and systemic sclerosis (SSc) to name a few. These conditions are all associated with higher rates of cardiovascular (CV) morbidity and mortality, which is driven primarily by atherosclerotic heart disease. Traditional risk factors are important considerations in the assessment of CV risk in the rheumatologic patient; however, these factors do not appear to impart a similar weight of risk in women with inflammatory autoimmune rheumatologic conditions. In addition, even when controlling for traditional risk factors, patients with RA or SLE continue to have a higher risk of CV events, which has been linked to the burden of systemic inflammation. Currently, the CV risk scoring systems available for the general population underestimate the burden of the problem in these complex patients. The increased CV risk in patients with rheumatologic diseases has been reported in the literature for years but remains underrecognized by internists and cardiologists. Although these conditions themselves are relatively rare, the further study of inflammation and its treatment in CV disease will be beneficial to the general population.
