Abstract
Background Different studies report that systemic lupus erythematosus (SLE) tends to have a more aggressive course in Hispanic patients. In this study, we analysed epidemiologic, clinical, and laboratory characteristics in a cohort of Hispanic and Caucasian lupus patients in the context of Italian health service, which provides free access to care to all citizens, thus mitigating the impact of socioeconomic factors that negatively influence the course of the disease in ethnic minorities. Methods This single-center retrospective study was conducted at the San Martino Hospital "Lupus Clinic" in Genoa, Italy. Patients ≥18 years with a confirmed diagnosis of SLE and definite ethnicity (Hispanic or Caucasian) were recruited. Results A total of 126 patients (90 Caucasians and 36 Hispanics) were enrolled. We compared epidemiologic characteristics, clinical features, autoantibodies profile, and treatment options without evidencing any statistically significant difference between the two groups, except for disease duration, which was higher in the Caucasian group (20.4 years versus 14.2 years in the Hispanic group, P=0.002) and SLICC damage index, which was greater in Caucasian patients (2.11 versus 1.88 in Hispanics, P=0.037), but this difference was no longer significant after correction for disease duration (P=0.096). Conclusions In our cohort, Hispanic ethnicity is not associated with worse disease features and outcomes. Therefore, we speculated that socioeconomic factors, in particular, free access to healthcare, might be more relevant in influencing the course of the disease than genetic background.

Abstract
OBJECTIVE Lupus nephritis (LN) is a major cause of morbidity and mortality in systemic lupus erythematosus (SLE). Despite multiple studies addressing healthcare disparities, disparate outcomes in LN persist. We investigate herein the association between socioeconomic status (SES) and LN as well as the association between SES, SLE disease activity index (SLEDAI), and treatment response. METHODS Patients were selected from the Southern California Lupus Registry (SCOLR), a registry enrolling all-comers with SLE. Analysis was completed on individuals with public vs. private insurance. Insurance and ethnicity were used as surrogate variables for SES, and we tested differences in means. RESULTS After adjusting for age and sex, public insurance was independently associated with the prevalence of LN. Analysis of 35 patients revealed greater proteinuria and mean SLEDAI in patients with public insurance at baseline and 6 months. Baseline, 6-, and 12-month SLEDAI means were significantly lower in Asian/Pacific Islanders (PI) compared to others. While non-Hispanic Whites demonstrated mean SLEDAI improvement over 6 months, Asians/PI, Blacks, and Hispanics demonstrated worsened disease activity on average. CONCLUSION Low SES, when defined by insurance, is associated with greater adverse outcomes in SLE. This is the first regional study that compares differences in treatment response in LN patients with low SES as well as association of SES with long-term outcomes in SLE and LN in southern California.

Abstract
Systemic lupus erythematosus (SLE) affects 1 in 537 Black women, which is >2-fold more than White women. Black patients develop the disease at a younger age, have more severe symptoms, and have a greater chance of early mortality. We used a multiomics approach to uncover ancestry-associated immune alterations in patients with SLE and healthy controls that may contribute biologically to disease disparities. Cell composition, signaling, epigenetics, and proteomics were evaluated by mass cytometry; droplet-based single-cell transcriptomics and proteomics; and bead-based multiplex soluble mediator levels in plasma. We observed altered whole blood frequencies and enhanced activity in CD8+ T cells, B cells, monocytes, and DCs in Black patients with more active disease. Epigenetic modifications in CD8+ T cells (H3K27ac) could distinguish disease activity level in Black patients and differentiate Black from White patient samples. TLR3/4/7/8/9-related gene expression was elevated in immune cells from Black patients with SLE, and TLR7/8/9 and IFN-α phospho-signaling and cytokine responses were heightened even in immune cells from healthy Black control patients compared with White individuals. TLR stimulation of healthy immune cells recapitulated the ancestry-associated SLE immunophenotypes. This multiomic resource defines ancestry-associated immune phenotypes that differ between Black and White patients with SLE, which may influence the course and severity of SLE and other diseases.

Characteristics and outcomes of a Hispanic lupus nephritis cohort from Mexico. Rheumatology (Oxford) 2023; 62:1136-1144. [PMID: 35822600 DOI: 10.1093/rheumatology/keac407] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 07/03/2022] [Accepted: 07/03/2022] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVES To characterize the clinical presentation and outcomes of LN in a Hispanic cohort from Mexico. METHODS We studied 440 subjects with systemic lupus erythematosus and biopsy-proven LN followed for >36 months. We obtained demographic, clinical, laboratory, histopathological and treatment variables. All outcomes were analysed by survival analysis and included response to therapy, renal relapses, progression of kidney disease (decline in eGFR ≥ 30%, doubling of serum creatinine, end-stage kidney disease) and patient survival. RESULTS The median age of the study cohort was 29 years (IQR 23-37) and 96% were female. The median eGFR at inclusion was 81 mL/min/1.73m2 (IQR 48-118) and 24 h-uPCR was 3.4 g/g (IQR 1.9-5.6). Mixed class LN (III/IV+V) was the most frequently observed (69%). Over a median follow-up of 79 months, complete response rates were 22.3%, 40.5% and 51.6%, at 6, 12 and 24 months, respectively. Renal relapse rates were 32.3% and 50.6% at 3 and 5 years. By 3 and 5 years, 20.7% and 31.4% had decline in eGFR ≥30%, 14.4% and 22.5% doubled their serum creatinine, and 9.1% and 17.7% progressed to ESKD. The factors associated with loss of kidney function were age, eGFR at presentation, the histologic chronicity index in the kidney biopsy, and the type of response to therapy. Patient survival was 98.2% and 97.1% at 3 and 5 years. CONCLUSION Although the response to treatment and patient survival in this Latin American cohort is comparable to that observed in other regions, there is still a high rate of renal relapses and progression to decline in kidney function.

Abstract
BACKGROUND No study has assessed the risk factors of progression from discoid lupus erythematosus (DLE) to severe systemic lupus erythematosus (sSLE) (defined as requiring hospitalization and specific treatment). OBJECTIVE To identify the risks factors of and generate a predicting score for progression to sSLE among patients with isolated DLE or associated with systemic lupus erythematosus with mild biological abnormalities. METHODS In this registry-based cohort study, multivariable analysis was performed using risk factors identified from literature and pruned by backward selection to identify relevant variables. The number of points was weighted proportionally to the odds ratio (OR). RESULTS We included 30 patients with DLE who developed sSLE and 134 patients who did not. In multivariable analysis, among 12 selected variables, an age of <25 years at the time of DLE diagnosis (OR, 2.8; 95% CI, 1.1-7.0; 1 point), phototype V to VI (OR, 2.7; 95% CI, 1.1-7.0; 1 point), and antinuclear antibody titers of ≥1:320 (OR, 15; 95% CI, 3.3-67.3; 5 points) were selected to generate the score. Among the 54 patients with a score of 0 at baseline, none progressed to sSLE, whereas a score of ≥6 was associated with a risk of approximately 40%. LIMITATIONS Retrospective design. CONCLUSION In our cohort, an age of <25 years at the time of DLE diagnosis, phototype V to VI, and antinuclear antibody titers of ≥1:320 were risk factors for developing sSLE.

Abstract
OBJECTIVE Lupus presents earlier and more severely among patients with skin of color (SOC), and this population experiences worse outcomes. Providers rely on medical education materials when developing skills to care for patients, yet these resources historically underrepresent patients with SOC and marginalize vulnerable populations. In this study, we investigated if this publication bias extends to images depicting patients with lupus. METHODS We reviewed published images of patients with lupus from rheumatology, dermatology, and internal medicine textbooks and medical journals, SOC atlases, online image libraries, UpToDate, and Google Images. We selected materials published from 2014 to 2019 that were available through our university's online medical library. We used the search terms "lupus" and "lupus rash" to identify images. We rated the skin color in each image using the New Immigrant Survey Skin Color Scale and categorized them as light, medium, or dark. We compared the frequencies of published skin tones with chi-square and odds ratio analyses. RESULTS We assessed the skin tone of 1,417 images. The significant majority (56.4%) of the images represented light skin (χ2 = 490.14, P < 0.001). After SOC atlases, journals were the most inclusive of images depicting dark skin tones. The specialty of dermatology was most inclusive of medium and darker skin tones. CONCLUSION Published images of lupus underrepresent patients with SOC, which may limit providers' ability to deliver care to the patients who are at greatest risk for complications.

Abstract
Aim To evaluate the diagnostic performance of the American College of Rheumatology (ACR)-1997, the Systemic Lupus International Collaborating Clinics (SLICC)-2012, and the European League against Rheumatism (EULAR)/ACR-2019 classification criteria in adult patients with systemic lupus erythematosus (SLE). Methods PubMed, Embase, Web of Science and Cochrane Library databases were searched for literature comparing the three classification criteria of ACR-1997, SLICC-2012 and EULAR/ACR-2019, which took clinical diagnosis as reference. Meta-analysis was used to evaluate and compare the sensitivity, specificity and diagnostic odds ratio of ACR-1997, SLICC-2012 and EULAR/ACR-2019. To assess the early diagnosis capability of the classification criteria, subgroups of patients with disease duration < 3 years and < 1 year were selected for comparison of sensitivity and specificity based on the inclusion of the original study. The sensitivity and specificity of each item in three sets of classification criteria were evaluated. In addition, the clinical and immunological characteristics of patients who did not meet the three classification criteria were compared. Results Nine original studies were included in the analysis, including 6404 SLE patients and 3996 controls. Results showed that the diagnostic odds ratios (95% confidence interval) of the SLICC-2012 [136.35 (114.94, 161.75)] and EULAR/ACR-2019 [187.47 (158.00, 222.42)] were higher than those of the ACR-1997 [67.53 (58.75, 77.63)]. Compared with ACR-1997[(0.86 (0.82, 0.89)], SLICC-2012[(0.96 (0.93, 0.97)] and EULAR/ACR-2019[(0.95 (0.92, 0.97)] had higher sensitivity. The specificity of the three classification criteria was similar: ACR-1997, SLICC-2012, and EULAR/ACR-2019 were 0.93 (0.89, 0.95), 0.86 (0.79, 0.91), and 0.91 (0.85, 0.95), respectively. The sensitivity of SLICC-2012 and EULAR/ACR-2019 were higher than that of ACR-1997 in early-course subgroups. Patients who did not meet ACR-1997 had more hypocomplementemia, patients who did not meet SLICC-2012 had more cutaneous lupus and photosensitivity, and patients who did not meet EULAR/ACR-2019 had more cutaneous lupus and leucopenia. Conclusions SLICC-2012 and EULAR/ACR-2019 have better diagnostic ability than the ACR-1997, and the sensitivity of the former two criteria is also higher than that of the latter; Moreover, the SLICC-2012 and EULAR/ACR-2019 for patients in the early stages of disease performed equally excellent.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disorder with significant health disparities, as it disproportionately and more severely affects vulnerable and disadvantaged population groups in the United States and around the world, that is, women, ethnic minorities, individuals living in poverty, less educated, and lacking medical insurance. Both, genetic and non-genetic factors, contribute to these disparities. To overcome these health disparities and reduce poor outcomes among disadvantaged SLE populations, interventions on non-genetic amendable factors, especially on social health determinants, are necessary.

Abstract
Pro-inflammatory immune system development, metabolomic defects, and deregulation of autophagy play interconnected roles in driving the pathogenesis of systemic lupus erythematosus (SLE). Lupus nephritis (LN) is a leading cause of morbidity and mortality in SLE. While the causes of SLE have not been clearly delineated, skewing of T and B cell differentiation, activation of antigen-presenting cells, production of antinuclear autoantibodies and pro-inflammatory cytokines are known to contribute to disease development. Underlying this process are defects in autophagy and mitophagy that cause the accumulation of oxidative stress-generating mitochondria which promote necrotic cell death. Autophagy is generally inhibited by the activation of the mammalian target of rapamycin (mTOR), a large protein kinase that underlies abnormal immune cell lineage specification in SLE. Importantly, several autophagy-regulating genes, including ATG5 and ATG7, as well as mitophagy-regulating HRES-1/Rab4A have been linked to lupus susceptibility and molecular pathogenesis. Moreover, genetically-driven mTOR activation has been associated with fulminant lupus nephritis. mTOR activation and diminished autophagy promote the expansion of pro-inflammatory Th17, Tfh and CD3+CD4-CD8- double-negative (DN) T cells at the expense of CD8+ effector memory T cells and CD4+ regulatory T cells (Tregs). mTOR activation and aberrant autophagy also involve renal podocytes, mesangial cells, endothelial cells, and tubular epithelial cells that may compromise end-organ resistance in LN. Activation of mTOR complexes 1 (mTORC1) and 2 (mTORC2) has been identified as biomarkers of disease activation and predictors of disease flares and prognosis in SLE patients with and without LN. This review highlights recent advances in molecular pathogenesis of LN with a focus on immuno-metabolic checkpoints of autophagy and their roles in pathogenesis, prognosis and selection of targets for treatment in SLE.

Abstract
OBJECTIVES Pure membranous (class V) lupus nephritis (LN) is considered a less aggressive phenotype, but tissue fibrosis and chronic kidney disease may still develop. This study aimed to elucidate the prognostic value of a history of class switch in pure membranous LN. METHODS We included LN patients with at least two clinically indicated kidney biopsies. New onset of end stage kidney disease (ESKD) was defined as estimated glomerular filtration rate < 15 ml/min/1.73m2, initiation of dialysis, or kidney transplantation. RESULTS Among 220 patients (542 biopsies), 199 (90%) were female, and 118 (54%) were African American, 59 (27%) Caucasian, with median age of 28 years at the first kidney biopsy. Patients with pure class V in a first biopsy converted to proliferative LN in 41% of cases. Pure class V in a repeat biopsy was preceded by proliferative LN in 52%. Trajectory analysis of up to 4 repeat biopsies revealed that ISN class switch may happen at any time, even after multiple biopsies with the same class. New onset ESKD was observed within 2 years in 5/56 (9%) patients with pure class V in a repeat biopsy. All 5 patients had proliferative LN in the first biopsy (log rank p= 0.024). CONCLUSIONS The conversion from proliferative to membranous (and vice-versa) is frequent in SLE. It can occur at any time in the course of disease, limiting the prognostic value of the first biopsy. Evidence of prior proliferative LN is key as it is associated with higher risk of ESKD in non-proliferative LN.

Abstract
OBJECTIVE To compare clinical and imaging features of multiple sclerosis (MS) severity between Black Americans (BA) and White Americans (WA) and evaluate the role of socioeconomic status. METHODS We compared BA and WA participants in the Multiple Sclerosis Partners Advancing Technology Health Solutions (MS PATHS) cohort with respect to MS characteristics including self-reported disability, objective neurologic function assessments, and quantitative brain MRI measurements, after covariate adjustment (including education level, employment, or insurance as socioeconomic indicators). In a subgroup, we evaluated within-race, neighborhood-level indicators of socioeconomic status (SES) using 9-digit ZIP codes. RESULTS Of 1,214 BAs and 7,530 WAs with MS, BAs were younger, had lower education level, and were more likely to have Medicaid insurance or be disabled or unemployed than WAs. BAs had worse self-reported disability (1.47-fold greater odds of severe vs. mild disability, 95% CI 1.18, 1.86) and worse performances on tests of cognitive processing speed (-5.06 fewer correct, CI -5.72, -4.41), walking (0.66 seconds slower, 95% CI 0.36, 0.96) and manual dexterity (2.11 seconds slower, 95% CI 1.69, 2.54). BAs had more brain MRI lesions and lower overall and gray matter brain volumes, including reduced thalamic (-0.77 mL, 95% CI -0.91, -0.64), cortical (-30.63 mL, 95% CI -35.93, -25.33), and deep (-1.58 mL, 95% CI -1.92, -1.23) gray matter volumes. While lower SES correlated with worse neuroperformance scores in WAs, this association was less clear in BA. CONCLUSION We observed a greater burden of disease in BAs with MS relative to WAs with MS, despite adjustment for SES indicators. Beyond SES, future longitudinal studies should also consider roles of other societal constructs (e.g., systemic racism). Such studies will be important for identifying prognostic factors and optimal treatment strategies among BAs with MS is warranted.

Abstract
Systemic lupus erythematosus (SLE) cohorts across the world have allowed better understanding of SLE, including its bimodal mortality, and the impact of social factors and ethnicity on outcomes. The representation of patients from South Asia has been poor in the existing SLE cohorts across the world. Hence, we planned to initiate an inception cohort to understand the diversity of lupus in India. Indian SLE Inception cohort for REsearch (INSPIRE), planned over 5 years is a multi-centric cohort of adult and childhood lupus patients of Indian origin, fulfilling the SLICC-2012 classification criteria, with an aim to provide cross-sectional information on demography, ethnicity, socio-economic status, standard disease variables, quality of life, and prospective information on new events like hospitalization, infections, pregnancies, changes in disease activity, and damage. One of the other deliverables of this project is the establishment of a biorepository. The instruments to be used for each variable and outcome were finalized, and a web-enabled case report form was prepared to encompass SLEDAI, BILAG, SLICC damage scores, and Lupus quality-of-life index.Ten centers located in different geographic areas of India would enroll patients who are seen for the first time after the start of the study. In the first 8 months, 476 patients (63 children, 36 males) have been enrolled with a median disease duration of 10 (IQR 4-17) months and mucocutaneous features being the most prevalent clinical manifestations. INSPIRE is the first prospective Indian SLE cohort to study the diversity of Indian patients.

Abstract
The Lupus in Minorities: Nature Vs Nurture (LUMINA) cohort has placed Hispanics on the lupus map in the United States. Texan Hispanic and African American patients experience, overall, worse outcomes than the Caucasian and Puerto Rican Hispanic patients. The genetic component of ethnicity is important early in the disease course whereas socioeconomic factors become more important subsequently. The role of hydroxychloroquine in preventing damage accrual and reducing mortality in lupus patients is a major contribution of LUMINA.

Abstract
Lupus nephritis, one of the most serious manifestations of systemic lupus erythematosus (SLE), has a heterogeneous clinical and pathological presentation. For example, proliferative nephritis identifies a more aggressive disease class that requires immunosuppression. However, the current classification system relies on the static appearance of histopathological morphology, which does not capture differences in the inflammatory response. Therefore, a biomarker grounded in the disease biology is needed in order to understand the molecular heterogeneity of lupus nephritis and identify immunologic mechanism and pathways. Here, we analyzed the patterns of 1000 urine protein biomarkers in 30 patients with active lupus nephritis. We found that patients stratify over a chemokine gradient inducible by IFN-γ. Higher values identified patients with proliferative lupus nephritis. After integrating the urine proteomics with the single-cell transcriptomics of kidney biopsies, we observed that the urinary chemokines defining the gradient were predominantly produced by infiltrating CD8+ T cells, along with natural killer and myeloid cells. The urine chemokine gradient significantly correlated with the number of kidney-infiltrating CD8+ cells. These findings suggest that urine proteomics can capture the complex biology of the kidney in lupus nephritis. Patient-specific pathways could be noninvasively tracked in the urine in real time, enabling diagnosis and personalized treatment.

Abstract
OBJECTIVE To examine the burden of comorbidities prior to and after the diagnosis of SLE and its impact on mortality. METHODS We identified 1605 incident cases of SLE and 6284 matched controls from the UK primary care. The risks of comorbidities before (prevalence; odds ratios) and after SLE diagnosis (incidence; hazard ratios) and the impact of comorbidities at diagnosis on all-cause mortality were estimated. RESULTS At diagnosis, SLE was associated with adjusted odds ratios (95% CI) of 2.25 (1.97-2.56), 3.37 (2.49-4.57) and 3.54 (1.89-6.63) for a Charlson comorbidity index of 1-2, 3-4 and ≥5, respectively. Following diagnosis, SLE also associated with increased risk of developing any comorbidity with an adjusted hazard ratio (95% CI) of 1.30 (95% CI, 1.13-1.49). At diagnosis, SLE was associated with a greater risk of cancer, cardiovascular, renal, liver, rheumatological and neurological diseases as well as depression, anaemia and psoriasis. Risks of developing incident comorbidity in the categories of neoplasm, cardiovascular, genitourinary, metabolic/endocrine, gastrointestinal and hepatic diseases, chronic pulmonary diseases, musculoskeletal/connective tissue and neurological diseases were higher in SLE patients. People with SLE had higher mortality risk compared with controls, with adjusted hazard ratio of 1.91 (95% CI, 1.62-2.26); after further adjusting for comorbidities this reduced to 1.64 (1.37-1.97). Comorbidities at SLE diagnosis accounted for 27.6% of the apparent difference in mortality between SLE patients and matched controls. CONCLUSION People with SLE have increased risks of multiple comorbidities both prior to and after diagnosis and this contributes significantly to all-cause mortality.

Abstract
OBJECTIVE Lupus low disease activity state (LLDAS) is a potential treat-to-target goal in systemic lupus erythematosus (SLE). This study determined predictors of time to reach LLDAS in a longitudinal cohort. METHODS Patients were grouped according to LLDAS status at cohort entry. Those who did not satisfy LLDAS at cohort entry were analyzed prospectively. The Kaplan-Meier approach was used to estimate the time to LLDAS. Cox regression was used to identify patient characteristics that were associated with time to LLDAS. RESULTS The probability of LLDAS attainment within 1 year was 52% for Caucasians, 36% for African Americans, and 33% for SLE patients with renal involvement. The median time to LLDAS was 1.1 years. In multivariable models, African American ethnicity, baseline prednisone >10 mg daily, hypocomplementemia, baseline damage, and baseline renal activity remained significant predictors of longer time to attain LLDAS, while disease duration <1 year and cutaneous activity were associated with earlier attainment. CONCLUSION LLDAS is potentially attainable in the majority of SLE patients. The time to LLDAS was found to be longer in African American patients with SLE. Characteristics of African American patients with SLE, such as renal activity and hypocomplementemia, were also independent predictors of slower attainment of LLDAS. These findings point to the need to include African American patients with SLE in both clinical and pharmaceutical research.

Abstract
Background Systemic lupus erythematosus (SLE) is regarded as a prototype autoimmune disease because it can serve as a means for studying differences between ethnic minorities and sex. Traditionally, all Hispanics have been bracketed within the same ethnic group, but there are differences between Hispanics from Spain and those from Latin America, not to mention other Spanish-speaking populations. Objectives This study aimed to determine the demographic and clinical characteristics, severity, activity, damage, mortality and co-morbidity of SLE in Hispanics belonging to the two ethnic groups resident in Spain, and to identify any differences. Methods This was an observational, multi-centre, retrospective study. The demographic and clinical variables of patients with SLE from 45 rheumatology units were collected. The study was conducted in accordance with Good Clinical Practice guidelines. Hispanic patients from the registry were divided into two groups: Spaniards or European Caucasians (EC) and Latin American mestizos (LAM). Comparative univariate and multivariate statistical analyses were carried out. Results A total of 3490 SLE patients were included, 90% of whom were female; 3305 (92%) EC and 185 (5%) LAM. LAM patients experienced their first lupus symptoms four years earlier than EC patients and were diagnosed and included in the registry younger, and their SLE was of a shorter duration. The time in months from the first SLE symptoms to diagnosis was longer in EC patients, as were the follow-up periods. LAM patients exhibited higher prevalence rates of myositis, haemolytic anaemia and nephritis, but there were no differences in histological type or serositis. Anti-Sm, anti-Ro and anti-RNP antibodies were more frequently found in LAM patients. LAM patients also had higher levels of disease activity, severity and hospital admissions. However, there were no differences in damage index, mortality or co-morbidity index. In the multivariate analysis, after adjusting for confounders, in several models the odds ratio (95% confidence interval) for a Katz severity index >3 in LAM patients was 1.45 (1.038–2.026; p = 0.02). This difference did not extend to activity levels (i.e. SLEDAI >3; 0.98 (0.30–1.66)). Conclusion SLE in Hispanic EC patients showed clinical differences compared to Hispanic LAM patients. The latter more frequently suffered nephritis and higher severity indices. This study shows that where lupus is concerned, not all Hispanics are equal.

Abstract
Health and health care disparities are present in every medical specialty, and stem from multiple etiologies. Within health care itself, issues mostly arise within medical providers and across a system with an inequitable distribution of care and resources. One potential way to address disparities is to educate our workforce, to not only know about disparities but to also actively advocate for underresourced and marginalized patients. In this review, the authors describe efforts being conducted in graduate medical education and seek to elucidate some of the curricula currently being developed and implemented in rheumatology.

Abstract
AIM The Lupus Low Disease Activity State (LLDAS) is a potential treat to target goal in systemic lupus erythematosus (SLE). SLE patients in LLDAS for more than half of the observation time have about a 50% lower risk of new organ damage and have reduced mortality. We identified predictors of being in LLDAS ≥50% of the observation time. METHODS A total of 2228 SLE patients who had at least three clinical visits were included. Percentage of time in LLDAS was calculated based on the proportion of days under observation. LLDAS-50 was defined as being in LLDAS for ≥50% of the observation time. We used the stepwise selection procedure in logistic regression to identify predictors of LLDAS-50. RESULTS A total of 1169 (52.5%) SLE patients, but only 37.6% of African Americans, achieved LLDAS-50. In the multivariable model, African American ethnicity, hypocomplementemia, serositis, renal activity, arthritis, anti-RNP, anti-dsDNA, vasculitis, malar rash, discoid rash, thrombocytopenia, and immunosuppressive use were negative predictors of LLDAS-50. Older age at diagnosis, longer disease duration, higher education level, and greater percentage of time taking hydroxychloroquine remained positive predictors of LLDAS-50. CONCLUSION In this large cohort, only 52.5% achieved LLDAS-50. This proportion was even less in African Americans. A higher percentage of time taking hydroxychloroquine was a modifiable positive predictor of LLDAS-50. Anti-RNP, anti-dsDNA, and low complement were negatively associated with LLDAS-50. Our findings further emphasize the importance of inclusion of African Americans in clinical trials and hydroxychloroquine adherence in both clinical practice and clinical trials.

Abstract
OBJECTIVE The objective of this report is to determine the impact of remission and low disease activity state (LDAS) on damage accrual and mortality in systemic lupus erythematosus (SLE) patients. PATIENTS AND METHODS Visits from the Lupus in Minority populations: Nature vs. Nurture (LUMINA) cohort were categorized into remission (Systemic Lupus Activity Measure (SLAM) score = 0 and prednisone ≤ 5 mg/day and no immunosuppressants), LDAS ((not on remission), SLAM score ≤ 3, prednisone ≤ 7.5 mg/day, no immunosuppressants), or neither: active. Remission and LDAS visits were combined because of the relatively small number of remission visits. Their impact on damage accrual and mortality were examined by Poisson and logistic multivariable regressions adjusting for variables known to affect these outcomes. RESULTS A total of 3879 visits for 558 patients (28% Caucasian, 37% African descent, 35% Hispanic) were studied. These visits corresponded to 71 in remission, 585 in LDAS, and 3223 active. The longer the percentage of time the patients were in remission/LDAS, the less damage accrual observed (rate ratio 0.1773 (95% confidence interval (CI) 0.1216 to 0.2584) p < 0.0001). A trend was observed in terms of mortality although statistical significance was not reached (odds ratio 0.303 (95% CI 0.063 to 1.456), p = 0.1360). CONCLUSIONS The longer the patient's state on Remission/LDAS, the less damage accrual that occurs. The protective effect on mortality was not statistically significant.

Abstract
Objectives Hispanics with systemic lupus erythematosus (SLE) in the United States have more severe disease and damage accrual compared with whites. Data on Hispanics of similar ancestry in geographically different locations is limited but essential in defining genetic and environmental factors for SLE. This study evaluates SLE disease burden in two Dominican communities, Washington Heights in New York City (NYC) and Santiago in the Dominican Republic (DR). Methods Disease activity (SLE Disease Activity Index 2000 (SLEDAI-2K)) and damage (Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI)) were cross-sectionally measured in 76 Dominican SLE patients from the Columbia University Lupus Cohort in NYC and compared with 75 Dominican SLE patients living in Santiago in the DR. Results Mean (±SD) age was 40 (±14) and 36 (±11) years for NYC and DR patients, respectively. Median disease duration was 8 years. Disease activity was mild in both groups (SLEDAI-2K of 3 in NYC versus 4 in the DR). NYC Dominicans had more discoid lesions, positive anti-dsDNA, and anti-SSB antibodies. Dominicans in the DR used more corticosteroids, had less medical insurance, lower educational level, and were more likely to be unemployed, whereas more Dominicans in NYC smoked. NYC patients had a higher SDI compared with SLE patients in the DR (0.96 versus 0.24, p < 0.0001). Statistical significance was maintained in adjusted analysis (1.26 versus 0.57, p < 0.0001). Conclusion SLE Dominican patients in NYC had a higher SDI than those in the DR. Longitudinal studies are needed to ascertain whether this difference is due to biological, environmental factors, immigration patterns or a survival bias.

Abstract
Systemic lupus erythematosus (SLE) primarily affects women of childbearing age. One of the major changes in SLE focuses on the timing of a successful pregnancy. In the past, pregnancy was strongly discouraged in SLE, especially in the presence of risk factors such as nephritis, use of immunosuppressive therapies, or positivity of specific autoantibodies such as anti-phospholipids and anti-Ro/SSA, La/SSBA. Thanks to our better knowledge on the disease and management, pregnancy success rates in SLE patients have significantly improved care by the a multidisciplinary team which fosters a successful pregnancy with minimal complications for the mother and fetus when the disease is inactive or in remission. This approach is based on a counseling phase before pregnancy, to assess SLE activity phase, specific medications, risk factors, and continues through pregnancy and lactation with significantly improved pregnancy outcomes. Further, we can now better define the risk of disease flares during pregnancy based on a better understanding of the changes in maternal immunity and its relationship with SLE-associated autoimmunity and chronic inflammation. There is wide consensus that women with SLE can have successful pregnancies as long as conception is planned in a phase of inactive disease, and when the patient is closely managed by a rheumatologist, high-risk OB/GYN, neonatologist, and other medical specialists as indicated. Preconception counseling is essential to assess the risk of both fetal and maternal complications as well as identify life-threatening contraindications. Particular attention should be used in those SLE cases that have nephritis, APS or positivity for aPL, pulmonary hypertension, and positive anti-Ro/SSA or anti-La/SSB antibodies. In conclusion, the use of specific guidelines on the management of SLE before and during pregnancy and lactation, and a better understanding of the use of immunosuppressive therapies have significantly increased pregnancy success.

Abstract
Systemic lupus erythematosus (SLE) is associated with significant mortality, morbidity and cost for the individual patient and society. In the United States, African Americans (AAs) have 3-4 times greater prevalence of lupus, risk of developing lupus at an earlier age and lupus-related disease activity, organ damage and mortality compared with whites. Evidence-based self-management interventions that incorporate both social support and health education have reduced pain, improved function and delayed disability among patients with lupus. However, AAs and women are still disproportionately affected by lupus. This article presents the argument that peer mentoring may be an especially effective intervention approach for AA women with SLE. SLE peers with a track record of success in lupus management and have a personal perspective that clinicians often lack. This commonality and credibility can establish trust, increase communication and, in turn, decrease disparities in healthcare outcomes.

Abstract
Background Epidemiological studies in systemic lupus erythematosus have been reported in the literature in many countries and ethnic groups. Although systemic lupus erythematosus in Jamaica has been described in the past, there has not been a detailed evaluation of systemic lupus erythematosus patients in urban Jamaica, a largely Afro-Caribbean population. The goal of this study was to describe the clinical features, particularly disease activity, damage index and immunological features, of 150 systemic lupus erythematosus subjects. Methods 150 adult patients (≥18 years) followed in rheumatology clinic at a tertiary rheumatology hospital centre (one of two of the major public referral centres in Jamaica) and the private rheumatology offices in urban Jamaica who fulfilled Systemic Lupus International Collaborating Clinics (SLICC) criteria were included. Data were collected by detailed clinical interview and examination and laboratory investigations. Hence demographics, SLICC criteria, immunological profile, systemic lupus erythematosus disease activity index 2000 (SLEDAI-2K) and SLICC/American College of Rheumatology (ACR) damage index (SDI) were documented. Results Of the 150 patients, 145 (96.7%) were female and five (3.3%) were male. The mean age at systemic lupus erythematosus onset was 33.2 ± 10.9. Mean disease duration was 11.3 ± 8.6 years. The most prevalent clinical SLICC criteria were musculoskeletal, with 141 (94%) of subjects experiencing arthralgia/arthritis, followed by mucocutaneous manifestations of alopecia 103 (68.7%) and malar rash 46 (30.7%), discoid rash 45 (30%) and photosensitivity 40 (26.7%). Lupus nephritis (biopsy proven) occurred in 42 (28%) subjects and 25 (16.7%) met SLICC diagnostic criteria with only positive antinuclear antibodies/dsDNA antibodies and lupus nephritis on renal biopsy. The most common laboratory SLICC criteria were positive antinuclear antibodies 136 (90.7%) followed by anti-dsDNA antibodies 95 (63.3%) and low complement (C3) levels 38 (25.3%). Twenty-seven (18%) met SLICC diagnostic criteria with only positive antinuclear antibodies/anti-dsDNA antibodies and lupus nephritis on renal biopsy. Mean SLEDAI score was 6.9 ± 5.1 with a range of 0–32. Organ damage occurred in 129 (86%) patients; mean SDI was 2.4 ± 1.8, with a range of 0–9. Conclusion These results are similar to the clinical manifestations reported in other Afro-Caribbean populations; however, distinct differences exist with respect to organ involvement and damage, particularly with respect to renal involvement, which appears to be reduced in our participants.

Abstract
For the treatment of proliferative lupus nephritis, long-term cyclophosphamide (CY) regimens are efficacious, however, at the expense of substantial toxicity. In the last decade, sequential regimens of short-term CY induction followed by either mycophenolate mofetil (MMF) or azathioprine (AZA) maintenance have shown to be efficacious and safe reducing the long-term exposure to CY. In a maintenance study including predominantly Hispanics and African-Americans, the patients who received MMF and AZA maintenance had a higher cumulative probability of remaining free of the composite of death or chronic renal failure (CRF) compared to quarterly intravenous CY (IVCY) maintenance (89% in MMF, 80%, in AZA and 45% in IVCY). Likewise, MMF and AZA maintenance were associated with significantly lower incidence of severe infections (2% in each MMF or AZA, and 25% in IVCY), sustained amenorrhea (6% in MMF, 8% in AZA, and 32% in IVCY), and hospitalizations (one hospital-days per patient-year in each MMF or AZA, and 10 in IVCY). In a European induction study including predominantly Caucasians, patients who received any of two sequential regimens, low dose versus high dose IVCY induction both followed by AZA maintenance, had a high cumulative probability of remaining free of treatment failure (84% in low dose IVCY and 80% in high dose IVCY; treatment failure defined as a composite of free of corticosteroid resistant flare, nephrotic syndrome, doubling creatinine, and persistent elevated creatinine). Low dose IVCY and high dose IVCY induction were associated with low incidence of sustained amenorrhea (4% in each group) and severe infections (11% in low dose and 22% in high dose IVCY induction). Of interest, most of the severe infection episodes occurred while patients were receiving IVCY induction. Finally an Asian study demonstrated that patients with proliferative lupus nephritis could be effectively treated with short-term oral CY induction followed by AZA maintenance. The cumulative probability of complete remission was 76%. The relapse rate was only 11%. The incidence of permanent amenorrhea and infection were 8% and 33%, respectively. None of the Asian patients had an increase in serum creatinine level to double the baseline value. Maintenance therapies with MMF or AZA following short-term CY induction in a sequential regimen are efficacious and safe for the treatment of high-risk patients with proliferative lupus nephritis.

Abstract
Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease that can potentially lead to serious organ complications and even death. Its global burden - in terms of incidence and prevalence, differential impact on populations, economic costs and capacity to compromise health-related quality of life - remains incompletely understood. The reported worldwide incidence and prevalence of SLE vary considerably; this variation is probably attributable to a variety of factors, including ethnic and geographic differences in the populations being studied, the definition of SLE applied, and the methods of case identification. Despite the heterogeneous nature of the disease, distinct patterns of disease presentation, severity and course can often be related to differences in ethnicity, income level, education, health insurance status, level of social support and medication compliance, as well as environmental and occupational factors. Given the potential for the disease to cause such severe and widespread organ damage, not only are the attendant direct costs high, but these costs are sometimes exceeded by indirect costs owing to loss of economic productivity. As an intangible cost, patients with SLE are, not surprisingly, likely to endure considerably reduced health-related quality of life.

Abstract
Objective The objective of this study was to determine the association of disease expression patterns with demographic and clinical characteristics in SLE. Methods Patients from a multi-ethnic SLE cohort were included. Disease expression patterns were defined as acute SLE and insidious SLE; this group was divided into those who accrued three ACR criteria and then accrued the fourth (insidious pattern A) and those who have one or two and then accrued four criteria (insidious pattern B). Disease activity was ascertained with the SLAM-R and disease damage with SLICC/ACR damage index. Variables were compared using analysis of variance for numeric variables and χ2 for categorical variables. Multivariable analyses adjusting for possible confounders were performed. Results Six hundred and forty patients were included; the most frequent pattern was the insidious pattern B, with 415 (64.8%) patients, followed by the acute SLE group with 115 (18.0%) and the insidious pattern A with 110 (17.2%) patients. Patients from the insidious pattern A were older at diagnosis (pattern A: 39.8 vs pattern B: 36.7 vs acute: 32.4 years; p < 0.0001), more educated (13.6 vs 13.1 vs 12.1; p = 0.0008) and with a less active disease at baseline (8.8 vs 9.2 vs 10.7; p = 0.0227). Caucasian and Hispanic (Puerto Rico) ethnicities were overrepresented in this group (40.0% vs 27.7% vs 19.1% and 18.2% vs 17.1% vs 9.6%; p = 0.0003). Conclusions More insidious onset is associated with older age, Caucasian ethnicity, higher level of education, and lower disease activity than those with acute onset. However, after multivariable analyses, disease activity was not associated with any disease expression pattern.

Intervention to Improve Quality of life for African-AmericaN lupus patients (IQAN): study protocol for a randomized controlled trial of a unique a la carte intervention approach to self-management of lupus in African Americans. BMC Health Serv Res 2016; 16:339. [PMID: 27485509 PMCID: PMC4971708 DOI: 10.1186/s12913-016-1580-6] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2015] [Accepted: 07/22/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Systemic Lupus Erythematosus (lupus) is a chronic autoimmune disease that can impact any organ system and result in life-threatening complications. African-Americans are at increased risk for morbidity and mortality from lupus. Self-management programs have demonstrated significant improvements in health distress, self-reported global health, and activity limitation among people with lupus. Despite benefits, arthritis self-management education has reached only a limited number of people. Self-selection of program could improve such trends. The aim of the current study is to test a novel intervention to improve quality of life, decrease indicators of depression, and reduce perceived and biological indicators of stress in African-American lupus patients in South Carolina. METHODS/DESIGN In a three armed randomized, wait list controlled trial, we will evaluate the effectiveness of a patient-centered 'a-la-carte' approach that offers subjects a variety of modes of interaction from which they can choose as many or few as they wish, compared to a 'set menu' approach and usual care. This unique 'a-la-carte' self-management program will be offered to 50 African-American lupus patients participating in a longitudinal observational web-based SLE Database at the Medical University of South Carolina. Each individualized intervention plan will include 1-4 options, including a mail-delivered arthritis kit, addition and access to an online message board, participation in a support group, and enrollment in a local self-management program. A 'set menu' control group of 50 lupus patients will be offered a standardized chronic disease self-management program only, and a control group of 50 lupus patients will receive usual care. Outcomes will include changes in (a) health behaviors, (b) health status, (c) health care utilization, and (d) biological markers (urinary catecholamines). DISCUSSION Such a culturally sensitive educational intervention which includes self-selection of program components has the potential to improve disparate trends in quality of life, disease activity, depression, and stress among African-American lupus patients, as better outcomes have been documented when participants are able to choose/dictate the content and/or pace of the respective treatment/intervention program. Since there is currently no "gold standard" self-management program specifically for lupus, this project may have a considerable impact on future research and policy decisions.

Abstract
There is no serologic test that reliably measures disease activity in systemic lupus erythematosus (SLE). The ‘gold standard’ is the anti-dsDNA antibody test, which has been used as a marker of disease activity by clinicians in SLE for over 35 years. Anti-dsDNA antibodies perform best in those with lupus nephritis, specifically in the presence of a proliferative lesion [World Health Organization (WHO) class III or IV] on renal biopsy. In one recent meta-analysis, the mean positivelikelihood ratio of anti-dsDNA antibodies as a marker of disease activity in SLE was 4.14, implying the overall predictive effect was small. More recently autoantibodyassays have been developed that show greater promise in gauging SLE disease activity, specifically anti-nucleosome and anti-C1q antibodies (especially with renal disease activity). Other tests thought previously to be lacking in specificity that refinements in ELISA technology now render possibly useful include anti-heparan sulfate, anti-ssDNA and anti-Scl-70 autoantibodies. Other tests that as yet have not been shown to be as reliable (and therefore are not as useful in clinical practice for serial determinationto measure disease activity) include other anti-extractablenuclear antibodies (anti-Ro, La, Sm, RNP), anti-cardiolipinantibodies, and anti-nuclear cytoplasmic antibodies (ANCA). New technologies using proteomic determinations show promise as aids in the search for more reliable and feasible autoantibody determinations of disease activity in SLE.

Abstract
This article is the first to review published research on psychosocial factors and behavioral interventions related to systemic lupus erythematosus (SLE). The first section presents descriptive studies, followed by studies that investigate psychosocial factors as predictor and outcome variables. These studies demonstrate that the consideration of psychosocial factors is critical to understanding the disease experience of persons with SLE. Next, studies of behavioral interventions are presented, leading to the conclusion that randomized controlled trials are essential yet rare. The final section highlights limitations of the extant literature and suggests directions for future research and recommendations for clinicians.

Abstract
The objective of this study was to examine factors predictive of a decline to low levels of disease activity in a cohort of systemic lupus erythematosus (SLE) patients. Patients with SLE of Hispanic (from Texas or Puerto Rico), African-American or Caucasian ethnicity from a multiethnic cohort were included. A decline to low levels of disease activity was defined as a score ≤5 as per the Systemic Lupus Activity Measure-Revised (SLAM-R) at any annual study visit if preceded by a SLAM-R 8. Using Generalized Estimating Equation (GEE), socioeconomic-demographic, behavioral, function, psychological, laboratory and clinical data [disease manifestations, number of ACR criteria accrued at diagnosis and damage accrual as per the Systemic Lupus International Collaborating Clinics (SLICC) Damage Index (SDI)] from the visit preceding that meeting the definition were examined as predictors of decline to low levels of disease activity. Two-hundred and eighty-seven patients (67 Hispanics from Texas, 32 Hispanics form Puerto Rico, 120 African-Americans and 68 Caucasians), accounting for 632 visits were analyzed. In the GEE multivariable analysis, higher degrees of social support (OR = 1.208, 95% CI 1.059-1.379; P = 0.005) were predictive of a decline to low levels of disease activity, while the number of ACR criteria accrued at diagnosis (OR = 0.765, 95% CI 0.631-0.927; P = 0.006) and damage (OR = 0.850, 95% CI 0.743-0.972, P = 0.018) were negatively associated. These data suggest that a decline to low levels of disease activity in lupus patients seems to be multifactorial; this study also underscores the importance of social support for lupus patients.

Abstract
The importance of ethnicity, socioeconomic status (SES), and autoantibodies as prognostic indicators in lupus were evaluated in a Canadian cohort. A retrospective review of 330 lupus patients identified demographic features including age and self reported ethnicity, SES, lupus features, antibodies to extractable nuclear antigens (ENAs), organ damage (SDI score), and mortality. ENA (Sm, RNP, Ro, La) associations with lupus features, predictors of final visit SDI score and the contributions of ethnicity, autoantibodies and SES on overall mortality were determined. Three ethnic groups [Caucasians (C), Asian-Orientals (AO), Native American First Nations (FN)] differed in disease severity and SES. FN and AO patients had similarly severe lupus, developing lupus at an earlier age, with more renal and neurological involvement, greater SDI scores at last visit, and more frequently had Sm or RNP antibodies than C. FN had the highest mortality and lowest SES. Sm and RNP antibodies were associated with renal and neurologic involvement. RNP, education and duration of follow-up predicted SDI score. Sm increased risk of death. In conclusion, RNP and lower SES are associated with lupus related organ damage and the presence of Sm is a predictor of mortality in lupus, independent of ethnicity, renal involvement or socioeconomic status.

Abstract
Objective.There are no laboratory tools that detect early flares in systemic lupus erythematosus (SLE). Our aim was to validate in our population the previous findings of the association of C4d-bearing reticulocytes (R-C4d) compared to anti-dsDNA antibodies, with disease activity assessed by the Safety of Estrogens in Lupus Erythematosus National Assessment–Systemic Lupus Erythematosus Disease Activity Index (SELENA-SLEDAI) and the British Isles Lupus Assessment Group (BILAG) 2004 scales.Methods.All patients who met the 1987 American College of Rheumatology classification criteria and were seen consecutively in 2013 at a specialized SLE care clinic were included. Disease activity was established by the SELENA-SLEDAI and BILAG 2004. Anti-dsDNA and R-C4d were quantified in peripheral blood. Comparisons were made between values of active and inactive patients, and the correlations between the SELENA-SLEDAI and serum levels of anti-dsDNA and R-C4d were measured.Results.Sixty-two patients (83.9% women) were included. A total of 32.3% had active disease according to the SELENA-SLEDAI. There was a significant statistical difference (p = 0.0001) in the distribution of R-C4d between disease activity groups. The correlation coefficient between R-C4d and the SELENA-SLEDAI score was rs = 0.738 (p = 0.0001). R-C4d differed between patients with and without activity in the BILAG 2004 constitutional, mucocutaneous, gastrointestinal, renal, and hematological domains.Conclusion.R-C4d showed a higher correlation with SLE activity measured by the SELENA-SLEDAI and BILAG 2004 than anti-dsDNA did, suggesting a possible involvement in diagnosing disease activity. Prospective studies that confirm these findings and evaluate its involvement in followup are needed.

Abstract
OBJECTIVE To evaluate disease features and outcomes in two populations with significant Amerindian ancestry. METHODS Hispanic patients (from Texas) from the Lupus in Minorities: Nature versus Nurture (LUMINA) cohort and Mestizo patients from the Grupo Latino Americano De Estudio del Lupus or Latin American Group for the Study of Lupus (GLADEL) cohort were included. Disease features and outcomes were evaluated at baseline and last visit. Admixture informative markers of Mestizo Genoma de Lupus Eritematoso Sistémico Network consortium (GENLES) patients and Hispanic LUMINA patients were compared. Univariable analyses were performed using Chi square or Student's t test as appropriate. Multivariable analyses adjusting for possible confounders were carried out using Poisson, logistic or Cox regression models as appropriate. RESULTS A total of 114 LUMINA and 619 GLADEL patients were included. GLADEL patients had accrued more damage at baseline, but the opposite was the case at last visit. Being from LUMINA was a risk factor for damage accrual, even after adjusting for possible confounders [relative risk (RR) 1.33, 95% CI 1.12, 1.58]. Also, LUMINA patients have a higher risk of mortality than GLADEL patients [hazard ratio (HR) 2.37, 95% CI 1.10, 5.15], having 5-year survival of 85.6% and 94.5%, respectively. In addition, 79 LUMINA patients and 744 Mestizo GENLES patients were evaluated in order to compare genetic ancestry between the two groups; GENLES patients had a higher proportion of European ancestry (48.5% vs 43.3%, P = 0.003) and a lower proportion of Asian ancestry (3.7% vs 4.9%, P = 0.048), but the proportions of Amerindian and African ancestry were comparable in both. CONCLUSION USA Hispanic patients seemed to have a poorer prognosis than their counterparts from Latin America, despite having a comparable genetic background. Socioeconomic factors may account for these observations.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by multiple organ involvement and pronounced racial and ethnic heterogeneity. The aims of the present work were (1) to describe the cumulative clinical characteristics of those patients included in the Spanish Rheumatology Society SLE Registry (RELESSER), focusing on the differences between patients who fulfilled the 1997 ACR-SLE criteria versus those with less than 4 criteria (hereafter designated as incomplete SLE (iSLE)) and (2) to compare SLE patient characteristics with those documented in other multicentric SLE registries.RELESSER is a multicenter hospital-based registry, with a collection of data from a large, representative sample of adult patients with SLE (1997 ACR criteria) seen at Spanish rheumatology departments. The registry includes demographic data, comprehensive descriptions of clinical manifestations, as well as information about disease activity and severity, cumulative damage, comorbidities, treatments and mortality, using variables with highly standardized definitions.A total of 4.024 SLE patients (91% with ≥4 ACR criteria) were included. Ninety percent were women with a mean age at diagnosis of 35.4 years and a median duration of disease of 11.0 years. As expected, most SLE manifestations were more frequent in SLE patients than in iSLE ones and every one of the ACR criteria was also associated with SLE condition; this was particularly true of malar rash, oral ulcers and renal disorder. The analysis-adjusted by gender, age at diagnosis, and disease duration-revealed that higher disease activity, damage and SLE severity index are associated with SLE [OR: 1.14; 95% CI: 1.08-1.20 (P < 0.001); 1.29; 95% CI: 1.15-1.44 (P < 0.001); and 2.10; 95% CI: 1.83-2.42 (P < 0.001), respectively]. These results support the hypothesis that iSLE behaves as a relative stable and mild disease. SLE patients from the RELESSER register do not appear to differ substantially from other Caucasian populations and although activity [median SELENA-SLEDA: 2 (IQ: 0-4)], damage [median SLICC/ACR/DI: 1 (IQ: 0-2)], and severity [median KATZ index: 2 (IQ: 1-3)] scores were low, 1 of every 4 deaths was due to SLE activity.RELESSER represents the largest European SLE registry established to date, providing comprehensive, reliable and updated information on SLE in the southern European population.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) patients have seriously impaired quality of life (QoL). In addition to activity and damage indices used in the past, tools to evaluate QoL in SLE have been developed in recent years. In this study, we test the validity of the Turkish version of the Lupus-QoL (LupusQoL-TR) score, and investigate its association with clinical findings and activity indices. METHODS A total of 132 patients diagnosed with SLE according to ACR 1997 criteria were included. The clinical and demographic features, and biochemical data were retrieved from hospital records. SLE Disease Activity Index (SLEDAI) and damage score (SLICC-ACR) were determined at the time of administration of Lupus-QoL questionnaire. The Lupus-QoL includes 34 questions divided into eight domains. We reevaluated the LupusQoL-TR and pretested its understandability. SLE patients were concomitantly administered the LupusQoL-TR and generic SF-36. Internal consistency, test-retest reliability, convergent and discriminant validity were calculated. RESULTS The mean age of our SLE patients was 37.9 ± 12.8 years. Internal consistency reliability ranged from 0.88 to 0.93, and test-retest reliability from 0.84 to 0.94. LupusQoL-related domains in SF-36 were correlated (from 0.66 to 0.74). Most LupusQoL-TR domains, except planning, were able to discriminate between active and inactive SLE groups. Scores in all domains of the LupusQoL-TR were found to be discriminative for patients with and without damage according to SLICC-ACR score. CONCLUSION The LupusQoL-TR was found to be a valid patient-reported outcome measure method when evaluating QoL in Turkish SLE patients.

Abstract
Background: Although the survival rate has considerably improved, many patients with systemic lupus erythematosus (SLE) develop irreversible organ damage. Objectives: The objectives of this paper are to characterize cumulative damage in SLE patients and identify variables associated with its presence and severity. Methods: A cross-sectional analysis of SLE patients from the Portuguese Lupus register Reuma.pt/SLE in whom damage assessment using the SLICC/ACR-Disability Index (SDI) was available was performed. Predictor factors for damage, defined as SDI ≥ 1, were determined by logistic regression analyses. A sub-analysis of patients with severe damage (SDI ≥ 3) was also performed. Results: In total, 976 patients were included. SDI was ≥1 in 365 patients, of whom 89 had severe damage. Musculoskeletal (24.4%), neuropsychiatric (24.1%) and ocular (17.2%) domains were the most commonly affected. Older age, longer disease duration, renal involvement, presence of antiphospholipid antibodies and current therapy with steroids were independently associated with SDI ≥ 1. The subpopulation with severe damage had, in addition, a greater interval between the first manifestation attributable to SLE and the clinical diagnosis as well as and more frequently early retirement due to SLE. Conclusions: This large lupus cohort confirmed that demographic and clinical characteristics as well as medication are independently associated with damage. Additionally, premature retirement occurs more often in patients with SDI ≥ 3. Diagnosis delay might contribute to damage accrual.

Abstract
Genetic factors seem to play a more important role early in the course of systemic lupus erythematosus (SLE), whereas nongenetic factors seem to play a more important role over the course of the disease. SLE is more frequent with less favorable outcomes in nonwhite populations. To overcome these differences and reduce the immediate-term, mediate-term, and long-term impact of SLE among disadvantaged populations, it is essential to increase disease awareness, to improve access to health care and to provide care to these patients in a consistent manner regardless of the severity of their disease.

Abstract
Objectives Studies regarding the epidemiology of systemic lupus erythematosus (SLE) are lacking in Argentina. Our purpose was to estimate the incidence and prevalence of SLE in a university hospital-based health management organisation in Buenos Aires (HIMCP). Methods For incidence calculation, the population at risk included all adult members of the HIMCP, with continuous affiliation for at least 1 year from January 1998 to January 2009. Each person was followed until he/she voluntarily left the HIMCP, death or finalisation of the study. Multiple methods for case finding were used to ensure complete ascertainment: (a) patients with problem SLE, undifferentiated autoimmune disease or mixed connective tissue disease in the Computer-based Patient Record System, (b) patients with positive antinuclear antibody test, anti-Sm antibodies and/or anti-dsDNA antibodies in the laboratory database and (c) patients who consumed hydroxichloroquine, chloroquine, azathioprine, cyclophosphamide, mycophenolate, cyclosporine or rituximab, from the administrative HIMCP drugs database. Medical records of all patients found were reviewed, and only patients fulfilling ACR criteria for SLE were included. Global and gender incidence rate (IR) was calculated. Prevalence was estimated on 1 January 2009, and the denominator population was the number of active members >18 years at that date (n=127 959). Results In the study period, 68 patients developed SLE. The observed IR (per 100 000 person-years, (CI 95%)) was 6.3 (4.9 to 7.7) for total population; 8.9 (CI 6.6 to 11.2) for women and 2.6 (1.2 to 3.9) for men. On 1 January 2009, 75 prevalent cases were identified. Prevalence rates (cases per 100 000 habitants, (CI 95%)) were 58.6 (46.1 to 73.5) for total population; 83.2 (63.9 to 106.4) for women and 23 (CI 11.9 to 40.1) for men. Conclusions SLE incidence and prevalence rates in Argentina are in agreement with those of other studies from different parts of the world.

Abstract
Ethnicity is a biological and a social construct which encompasses ancestral genes, cultural, geographic and socioeconomic characteristics shared within a population. It is clear that no homogeneous racial groups exist within the human race as demonstrated when examining ancestry informative markers. Both the genetic and non-genetic components of ethnicity exert influence in the expression and outcome of systemic lupus erythematosus (SLE), including disease activity, damage accrual, work disability and mortality. Although it is difficult to determine the extent to which the differences observed in these parameters are caused by genetic or non-genetic factors, early in the disease genetic factors seem to play a more important role as determinants of the differences observed between SLE patients from various ethnic groups. Over the course of the disease, non-genetic factors seem to play a more important role. By and large, SLE is more frequent and more severe with higher disease activity and more damage accrual in non-Caucasian populations (Hispanics, African descendants and Asians) than in Caucasians. To overcome these differences it is necessary to optimize health care access to disadvantaged populations and use innovative tools to increase disease awareness and improve treatment adherence.
