Hsu TC, Yang YH, Wang LC, Lee JH, Yu HH, Lin YT, Hu YC, Chiang BL. Risk factors for subsequent lupus nephritis in patients with juvenile-onset systemic lupus erythematosus: a retrospective cohort study. Pediatr Rheumatol Online J 2023; 21:28. [PMID: 36964531 PMCID: PMC10039593 DOI: 10.1186/s12969-023-00806-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Accepted: 03/08/2023] [Indexed: 03/26/2023] Open
Abstract
BACKGROUND Lupus nephritis (LN) is a crucial organ involvement in systemic lupus erythematosus (SLE). Patients with LN have higher morbidity and mortality rates than those without. Among all patients with LN, 20-40% had delayed onset, but the data for patients with juvenile-onset SLE (jSLE), who have a higher percentage of LN than patients with adult-onset SLE (aSLE), were limited. This study aimed to determine the risk factors for subsequent LN in patients with jSLE. METHODS A retrospective cohort study was conducted between 2008 and 2018 in a single tertiary medical centre. Patients with diagnosed jSLE were reviewed. We investigated those without LN at diagnosis and whether they developed LN afterward. The primary outcome was the development of subsequent LN. Clinical manifestations at diagnosis, serial laboratory data, and treatments were reviewed during follow-up periods. RESULTS Among the 48 patients with jSLE without initial LN, 20 developed subsequent LN later (Group 1), whereas 28 remained free of LN (Group 2). There was no difference in the percentage of initial manifestations except for more discoid rashes in Group 2 patients. In the Cox regression model, elevated average anti-double-stranded DNA (dsDNA) antibody, low average serum complements, and high average erythrocyte sedimentation rate (ESR) levels during follow-up were predictors of subsequent LN. After adjusting for these factors in multivariable analyses, only high average anti-dsDNA antibody and high average ESR levels remained predictive of subsequent LN. For every 100 IU/ml increase in anti-dsDNA antibody, the risk for subsequent LN in jSLE increases by 1.29 times (hazard ratio = 1.29, 95% confidence interval 1.055-1.573). CONCLUSION Persistently high anti-dsDNA antibody and ESR levels during the follow-up period were risk factors for subsequent LN in patients with jSLE.

[PMID: 35916201 DOI: 10.1111/1756-185x.14413] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 05/31/2022] [Accepted: 07/03/2022] [Indexed: 11/30/2022]
Abstract
The prevalence of systemic lupus erythematosus (SLE) is higher in Asians than Caucasians, with higher frequency of renal and other major organ manifestations that carry a poorer prognosis. The outcome of SLE is still unsatisfactory in many parts of the Asia Pacific region due to limited access to healthcare systems, poor treatment adherence and adverse reactions to therapies. The Asia Pacific League of Associations for Rheumatology (APLAR) SLE special interest group has recently published a set of consensus recommendation statements for the management of SLE in the Asia Pacific region. The current article is a supplement of systematic literature search (SLR) to the prevalence and treatment of non-renal manifestations of SLE in Asian patients.

Abstract
OBJECTIVES Systemic lupus erythematosus (SLE) in Asians is a unique patient group that has been thought to present with more severe organ involvement in comparison to their non-Asian counterparts. We set out to perform a meta-analysis to compare clinical manifestations between ancestries, with a focus on Southeast Asian ethnicities and gender. MATERIALS AND METHODS A cross-sectional study was performed in conjunction with a meta-analysis to identify differences in prevalences of SLE clinical manifestations. Searches were conducted on Medline for articles comparing between: (i) Asian and non-Asian ancestry; (ii) Southeast Asian ethnicities (Chinese, Malay and Indian); and (iii) male and female Asians. Using random effects model, effect sizes as odd ratios were pooled with DerSimonian and Laird's model. RESULTS A total of 13 articles were identified and pooled together with our study for this meta-analysis. Comparing among patients of Asian with Non-Asian/European ancestries, no significance difference was found in severe organ manifestations such as renal and neurological involvement [odds ratio (OR): 1.398, p= 0.320 and OR: 1.224, p= 0.526 respectively]. There was significantly greater proportion of Asian SLE patients with thrombocytopenia compared to non-Asian SLE. Chinese SLE patients were less likely to have oral ulcers compared to Indian SLE patients. Lastly, Asian male SLE patients had greater incidence of renal involvement and thrombocytopenia compared to Asian female SLE patients. CONCLUSIONS Severe SLE manifestations such as renal and neurological involvement were not significantly more frequent in Asian SLE compared to non-Asian/European SLE in this analysis.

Abstract
AIM To evaluate the performance of the 2019 European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) classification criteria for systemic lupus erythematosus (SLE) in a multi-ethnic Malaysian cohort and to compare it against the Systemic Lupus International Collaborating Clinics (SLICC) 2012 and ACR 1997 criteria. METHOD We conducted a retrospective observational study of 205 patients with a diagnosis of SLE and 100 controls who formed the validation cohort. The sensitivity and specificity of the three classification criteria were evaluated and a further sub-analysis was performed in patients with early disease and among the various ethnicities. RESULTS The sensitivities and specificities of the three classification criteria are as follows: EULAR/ACR (90.8%; 94%), SLICC 2012 (96.1%; 94%), and ACR 1997 (82%; 96%). Among patients with early disease, the sensitivity of the SLICC 2012 was higher than that of EULAR/ACR and ACR 1997 (98% vs 94% and 86%); however, the specificity of EULAR/ACR and ACR 1997 were similar (95.2%) and higher than the SLICC 2012 (93.5%). The SLICC 2012 had higher sensitivity than that of the EULAR/ACR among the Malays (94% vs 90%), Chinese (98% vs 90%), and Indians (100% vs 95%). The specificity of the EULAR/ACR and SLICC 2012 were similar in the Malay and Chinese (93.3% each, and 92% vs 94.6%). CONCLUSION The EULAR/ACR performed well in our cohort. The EULAR/ACR and SLICC 2012 showed higher sensitivity than the ACR 1997, and the EULAR/ACR showed similar specificity to the ACR 1997 and SLICC 2012 overall, in early disease, and across the different ethnicities.

Abstract
Childhood onset systemic lupus erythematosus is a rare disease that is more common amongst Southeast Asian children compared to the West. It is typified by a peripubertal onset and a female preponderance, which increases with advancing age. Organs commonly involved at diagnosis include haematological, renal, and mucocutaneous. Fever, malar rash, and cutaneous vasculitis are common. Lupus nephritis is typically proliferative especially Class IV and contributes to both disease activity and damage. Antinuclear antibody and anti-dsDNA positivity are both prevalent in this region. Disease activity is higher than Western cohorts at onset but responds to therapy reducing to low disease activity by six months. However, organ damage occurs early and continues to accumulate over the time, a consequence of both active disease (neurological and renal systems) and steroid-related complications especially in the eye (cataract and glaucoma) and musculoskeletal systems (avascular necrosis). Infections remain the leading cause of death and mortality in this region is highly variable contributed by the heterogeneity in social economic status, healthcare access, and availability of paediatric rheumatology expertise in the region.

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
AIM We aimed to characterize work disability in patients with newly diagnosed rheumatic diseases and compare work characteristics between patients with rheumatic diseases and controls without rheumatic diseases at diagnosis. METHODS Patients with inflammatory arthritis (IA) and osteoarthritis (OA), surrogates for autoimmune and non-autoimmune rheumatic diseases, respectively, and controls of working age were surveyed at diagnosis. Patients with rheumatic diseases who were employed before symptom onset were characterized as having work disability if they reported reduced work ability and productivity while remaining in the same job as before symptom onset, changed to a less demanding job or stopped working/retired. Work characteristics at diagnosis were compared between rheumatic diseases patients and controls. RESULTS The unemployment rate before symptom onset was lower in patients with IA (20%) compared to patients with OA (32%). Among patients with IA and OA who were employed before symptom onset, 59% and 43% reported work disability, respectively (P = .04). The unemployment rate at diagnosis was comparable in patients with IA (26%) and higher in patients with OA (38%) compared to controls (29%). Employed patients with IA and OA, when compared with controls, reported poorer work ability (score: 37 vs 39 vs 41, P < .01; proportion with poor/moderate work ability: 48% vs 33% vs 21%, P < .01) and greater work productivity loss (score: 32 vs 29 vs 17, P < .01) at diagnosis. CONCLUSION Rheumatic diseases impose significant work disability at diagnosis, highlighting the need for identification and interventions targeting work disability early in the course of disease.

Abstract
OBJECTIVE The aim of this study was to identify whether comorbidity status is associated with organ damage in patients with systemic lupus erythematosus (SLE). METHODS A total of 502 patients with SLE enrolled in the KORean lupus Network were consecutively recruited. Data included demographics, age-adjusted Charlson Comorbidity Index (CCIa), disease activity indexes, the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI), the Medical Outcomes Study Short Form-36 health survey (SF-36) score, and the Beck Depression Inventory (BDI) score. RESULTS Of the total patients, 21.1% (n = 106) experienced organ damage (SDI ≥ 1). Univariate correlation analysis revealed that SDI was not statistically correlated with any clinical variables (correlation coefficient r < 0.3 of all). There were significant differences in the BDI, mental component score of the SF-36, Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), CCIa, C-reactive protein, and mean dose of corticosteroid between non-damage (SDI = 0) and damage (SDI ≥ 1) groups. The presence of damage to at least 1 organ in patients with SLE was found to be closely related with higher CCIa, higher SLEDAI, and mean dose of corticosteroid (OR 1.884, 95% CI 1.372-2.586, p < 0.001; OR 1.114, 95% CI 1.041-1.192, p = 0.002; OR 1.036, 95% CI 1.004-1.068, p = 0.026; respectively) in binary logistic regression analysis. CONCLUSION This study suggests that organ damage as assessed by the SDI in Korean patients with SLE is related to comorbidities together with disease activity and corticosteroid exposure.

Abstract
BACKGROUND Some rheumatologic disorders may initially manifest with central nervous system (CNS) affection, mimicking the clinical, magnetic resonance imaging, and cerebrospinal fluid findings of multiple sclerosis (MS). The MRZ reaction (MRZR), composed of the three respective antibody indices (AIs) against measles, rubella, and varicella zoster virus, has been found positive frequently in MS patients. However, it is unclear whether the MRZR is helpful to distinguish rheumatologic disorders with CNS involvement (RDwCNS) from MS. METHODS The MRZR was evaluated in patients with RDwCNS (n = 23), MS (n = 46; age and sex matched to patients with RDwCNS), and other inflammatory autoimmune neurological diseases affecting the CNS (OIND; n = 48). Both the stringency levels that have been used in previous MRZR studies, MRZR-1 (≥ 1 of 3 AIs positive) and MRZR-2 (≥ 2 of 3 AIs positive), were applied. RESULTS There was no statistically significant difference in the prevalence of positive MRZR between patients with RDwCNS (MRZR-1: 13.0% and MRZR-2: 8.7%, respectively) and OIND (MRZR-1: 22.9% and MRZR-2: 8.3%, respectively). Compared to these two study cohorts, the MS group exhibited significantly higher prevalences of positive MRZR (MRZR-1: 82.6%, MRZR-2: 63.0%; p < 0.005 each). CONCLUSIONS Considering the high specificity of MRZR-2 for MS found in this study, MRZR-2 can be a useful diagnostic tool for distinguishing MS from RDwCNS or OIND.

[PMID: 29550111 DOI: 10.1016/j.semarthrit.2018.01.010] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2017] [Revised: 01/15/2018] [Accepted: 01/22/2018] [Indexed: 10/18/2022]
Abstract
OBJECTIVES Phenotypes differ between late- and early-onset systemic lupus erythematosus (SLE). Prior studies suggested that there may be more pulmonary disease among late-onset patients. Our objective was to perform a systematic review and meta-analysis to evaluate the differences in pulmonary manifestations in late- versus early-onset SLE. METHODS We searched the literature using PubMed, CINAHL, Web of Science, Cochrane Library, and EMBASE. We excluded studies that did not include American College of Rheumatology SLE classification criteria, an early-onset SLE comparison group, or those that defined late-onset SLE as <50 years of age. We rated study quality using the Newcastle-Ottawa Quality Scale. We used Forest plots to compare odds ratios (95% confidence intervals) of pulmonary manifestations by age. Study heterogeneity was assessed using I2. RESULTS Thirty-nine studies, representing 10,963 early-onset and 1656 late-onset patients with SLE, met eligibility criteria. The odds of developing several pulmonary manifestations were higher in the late-onset group. Interstitial lung disease (ILD) was nearly three times more common (OR = 2.56 (1.27, 5.16)). Pleuritis (OR = 1.53 (1.19, 1.96)) and serositis (OR = 1.31 (1.05, 1.65)) were also more common in the late-onset group. The mean Newcastle-Ottawa Quality Scale score for study quality was moderate (6.3 ± 0.7, scale 0-9). CONCLUSIONS Pulmonary manifestations of SLE were more common in late-onset SLE patients compared to their younger peers, in particular ILD and serositis. Age-related changes of the immune system, tobacco exposure, race, and possible overlap with Sjögren's syndrome should be examined in future studies.

Abstract
INTRODUCTION Systemic lupus erythematosus (SLE) is a disease distributed worldwide, which occurs in both genders, and across racial/ethnic and age groups; however, higher rates are observed in adults, in women and in non-Caucasians. Genetic, environmental, sociodemographic and methodological issues are responsible not only for these differences but for the variable course and outcome of the disease. Non-Caucasians have a more severe disease with a higher risk for early mortality and damage accrual. Males also have a more severe disease; however, a negative impact of male gender on lupus outcomes has not been firmly established. Childhood-onset is associated with a more severe disease; moreover, it is also associated with higher damage and diminished survival; finally, late-onset lupus is mild but it is associated with higher damage accrual and a diminished survival. Areas covered: In this review, we discuss the incidence and prevalence of SLE, the impact of age, gender and race/ethnicity in SLE and in the survival of those affected. Expert commentary: Age, gender and race/ethnicity impact disease expression in SLE patients; despite improvements in survival, mortality in SLE remains almost three times higher than in the general population.

Associations of B cell-activating factor (BAFF) and anti-BAFF autoantibodies with disease activity in multi-ethnic Asian systemic lupus erythematosus patients in Singapore. Clin Exp Immunol 2017; 189:298-303.

Abstract
To measure the levels of B cell-activating factor (BAFF) and endogenous anti-BAFF autoantibodies in a cohort of multi-ethnic Asian systemic lupus erythematosus (SLE) patients in Singapore, to determine their correlation with disease activity. Serum samples from 121 SLE patients and 24 age- and sex-matched healthy controls were assayed for BAFF and anti-BAFF immunoglobulin (Ig)G antibody levels by enzyme-linked immunosorbent assay (ELISA). The lowest reliable detection limit for anti-BAFF-IgG antibody levels was defined as 2 standard deviations (s.d.) from blank. Correlation of serum BAFF and anti-BAFF IgG levels with disease activity [scored by SLE Activity Measure revised (SLAM-R)], and disease manifestations were determined in these 121 patients. SLE patients had elevated BAFF levels compared to controls; mean 820 ± 40 pg/ml and 152 pg ± 45/ml, respectively [mean ± standard error of the mean (s.e.m.), P < 0·01], which were correlated positively with anti-dsDNA antibody levels (r = 0·253, P < 0·03), and SLAM-R scores (r = 0·627, P < 0·01). In addition, SLE patients had significantly higher levels of anti-BAFF IgG, which were correlated negatively with disease activity (r = -0·436, P < 0·01), levels of anti-dsDNA antibody (r = -0·347, P < 0·02) and BAFF (r = -0·459, P < 0·01). The majority of patients in this multi-ethnic Asian SLE cohort had elevated levels of BAFF and anti-BAFF antibodies. Anti-BAFF autoantibody levels correlated negatively with clinical disease activity, anti-dsDNA and BAFF levels, suggesting that they may be disease-modifying. Our results provide further information about the complexity of BAFF pathophysiology in different SLE disease populations and phenotypes, and suggest that studies of the influence of anti-cytokine antibodies in different SLE populations will be required when selecting patients for trials using targeted anti-cytokine therapies.

Association of the lupus low disease activity state (LLDAS) with health-related quality of life in a multinational prospective study. Arthritis Res Ther 2017; 19:62. [PMID: 28320433 PMCID: PMC5359963 DOI: 10.1186/s13075-017-1256-6] [Citation(s) in RCA: 90] [Impact Index Per Article: 12.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2016] [Accepted: 02/09/2017] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is associated with significant impairment of health-related quality of life (HR-QoL). Recently, meeting a definition of a lupus low disease activity state (LLDAS), analogous to low disease activity in rheumatoid arthritis, was preliminarily validated as associated with protection from damage accrual. The LLDAS definition has not been previously evaluated for association with patient-reported outcomes. The objective of this study was to determine whether LLDAS is associated with better HR-QoL, and examine predictors of HR-QoL, in a large multiethnic, multinational cohort of patients with SLE. METHODS HR-QoL was measured using the Medical Outcomes Study 36-item short form health survey (SF-36v2) in a prospective study of 1422 patients. Disease status was measured using the SLE disease activity index (SLEDAI-2 K), physician global assessment (PGA) and LLDAS. RESULTS Significant differences in SF-36 domain scores were found between patients stratified by ethnic group, education level and damage score, and with the presence of active musculoskeletal or cutaneous manifestations. In multiple linear regression analysis, Asian ethnicity (p < 0.001), a higher level of education (p < 0.001), younger age (p < 0.001) and shorter disease duration (p < 0.01) remained significantly associated with better physical component scores (PCS). Musculoskeletal disease activity (p < 0.001) was negatively associated with PCS, and cutaneous activity (p = 0.04) was negatively associated with mental component scores (MCS). Patients in LLDAS had better PCS (p < 0.001) and MCS (p < 0.001) scores and significantly better scores in multiple individual SF-36 domain scores. Disease damage was associated with worse PCS (p < 0.001), but not MCS scores. CONCLUSIONS Ethnicity, education, disease damage and specific organ involvement impacts HR-QoL in SLE. Attainment of LLDAS is associated with better HR-QoL.

Abstract
Background: Modern medicine recognizes that salient, inherent variations between Caucasians and Asians exist. Radical changes are occurring in the health scene with increasing emphasis centered on the recognition of inter-individual variations unique to Asians that impact on medical management and outcomes. Aim: This review analyzes distinct features or outcomes in terms of epidemiology, disease thresholds, diagnostic cutoffs and treatment responses of Asian people compared with non-Asians. Methods: This review is based on a literature search via PubMed and MEDLINE for relevant articles related to the Asian phenotype and its impact on health and disease. Results: An 'Asian phenotype' could be characterized across the spectrum of biomedical disciplines and underscores the major challenges clinicians must face in their daily management of a cosmopolitan population and their extrapolation of research outcomes. Conclusion: Interventions for various ailments that have traditionally ignored population differences have now entered the age of personalized, stratified or precision medicine requiring an individualized approach being adopted as a new standard of care. Factoring in Asian phenotypes is essential for the medical research community and the development of improved clinical practice guidelines across a continuum of disciplines that will ultimately translate to better human health round the world.

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
Ethnicity is a key factor impacting on disease severity in SLE, but molecular mechanisms of these associations are unknown. Type I IFN and MIF have each been associated with SLE pathogenesis. We investigated whether increased SLE severity in Asian patients is associated with either MIF or Type I IFN. SLE patients (n = 151) had prospective recording of disease variables. Serum MIF, and a validated composite score of three Type I IFN-inducible chemokines (IFNCK:CCL2, CXCL10, CCL19) were measured. Associations of MIF and IFNCK score with disease activity were assessed, with persistent active disease (PAD) used as a marker of high disease activity over a median 2.6 years follow up. In univariable analysis, MIF, IFNCK score and Asian ethnicity were significantly associated with PAD. Asian ethnicity was associated with higher MIF but not IFNCK score. In multivariable logistic regression analysis, MIF (OR3.62 (95% CI 1.14,11.5), p = 0.03) and Asian ethnicity (OR3.00 (95% CI 1.39,6.46), p < 0.01) but not IFNCK were significantly associated with PAD. These results potentially support an effect of MIF, but not Type I IFN, in heightened SLE disease severity in Asian SLE. The associations of MIF and Asian ethnicity with PAD are at least partly independent.

Abstract
Neuropsychiatric (NP) involvement in Systemic Lupus Erythematosus (SLE), can be a severe and troubling manifestation of the disease that heavily impacts patient's health, quality of life and disease outcome. It is one of the most complex expressions of SLE which can affect central, peripheral and autonomous nervous system. Complex interrelated pathogenetic mechanisms, including genetic factors, vasculopathy, vascular occlusion, neuroendocrine-immune imbalance, tissue and neuronal damage mediated by autoantibodies, inflammatory mediators, blood brain barrier dysfunction and direct neuronal cell death can be all involved. About NPSLE a number of issues are still matter of debate: from classification and burden of NPSLE to attribution and diagnosis. The role of neuroimaging and new methods of investigation still remain pivotal and rapidly evolving as well as is the increasing knowledge in the pathogenesis. Overall, two main pathogenetic pathways have been recognized yielding different clinical phenotypes: a predominant ischemic-vascular one involving large and small blood vessels, mediated by aPL, immune complexes and leuko-agglutination which it is manifested with more frequent focal NP clinical pictures and a predominantly inflammatory-neurotoxic one mediated by complement activation, increased permeability of the BBB, intrathecal migration of autoantibodies, local production of immune complexes and pro-inflammatory cytokines and other inflammatory mediators usually appearing as diffuse NP manifestations. In the attempt to depict a journey throughout NPSLE from diagnosis to a reasoned therapeutic approach, classification, epidemiology, attribution, risk factors, diagnostic challenges, neuroimaging techniques and pathogenesis will be considered in this narrative review based on the most relevant and recent published data.

Abstract
This study demonstrates demographic, clinical and laboratory characteristics with special reference to infections in Saudi patients with SLE. One-hundred and ninety-nine patients with SLE treated at Riyadh Armed Forces Hospital, Saudi Arabia over a period of 15 years (1990—2005) were retrospectively reviewed. There were 162 females and 37 males (4.4 : 1) with an average age of 35 years at onset of disease. Duration of diseases ranged from one to 23 years with a mean of 7.23 years. Some of the clinical characteristics of SLE patients observed were nephritis (53.7%), fever (53.26%), neuropsychological disorder (36.18%), malar/butterfly rash (27.6%), pulmonary disorder (22.6%), photosensitivity (21.6%), cardiac involvement (21.1%) and oral ulcers (19.09%). Infection was the major complication with 58.79% of SLE patient having suffered from various infections. A total of 22 species of pathogens including gram positive and gram negative bacteria, viruses and fungi were isolated from 117 SLE patients. Single to multiple episode of infection with various pathogens were recorded however, majority of patients harboured one or two species of pathogens. Bacterial infection was predominant (78.6%) followed by viral (28.2%) and fungal (28.2%) infections. Forty-four percent of SLE patients were found to be infected with organisms classified as opportunistic. The high incidence of infections in SLE patients may be attributed to the multiple intrinsic and extrinsic risk factors including deficiency of complement (C3 and C4), disease activity, renal impairment, use of glucocorticoid and cytotoxic drugs. It is concluded that more judicious use of corticosteroids and other immunosuppressive agents will be critical to limit the infections in SLE and a high alert and close monitoring of patients will ensure optimal patient outcome, both in terms of morbidity and mortality.

Abstract
We studied the clinical course of 26 systemic lupus erythematosus(SLE) patients who started regular dialysis at our hospital and whose stay exceeded a three-month duration in order to investigate the long-term prognosis in a Chinese cohort. Clinical and serological activities of lupus before and after dialysis were analysed. To compare the long-term survival rate, controls were set using 78 age-matched end-stage renal disease (ESRD) patients who did not have SLE or diabetes mellitus and entered the chronic dialysis program at a similar period with SLE dialysis patients. There was a significant decrease in clinical lupus activity after starting regular dialysis (P < 0.05); however, the serologicalactivity remained the same. The five-and ten-yearsurvivalrates were significantly lower in the SLE patients (73 and 38% in the SLE group versus 95 and 88% in the non-SLE group, P < 0.05). SLE patients had a 4.3-times higher risk of death than non-SLE patients (P < 0.05, 95% confidence interval,1.2-15.2). Also, the deceased SLE patients had persistent lower serum levels of complement 3. SLE patients with ESRD remain clinically quiescent despite persistent serological abnormalities and have a worse prognosis than other uremia patients in the Chinese population.

Abstract
Clinical features of systemic lupus erythematosus (SLE) have been described from different geographical regions in the world, with some clinical differences among different racial groups. Although data on the characteristics of SLE in Pakistan is scarce, it is not uncommon in the South East Asian region. The purpose of this study was, therefore, to delineate the clinical pattern and disease course in Pakistani patients with SLE and to compare it with international data on lupus patients. A total of 196 patients with SLE fulfilling the clinical and laboratory criteria of the American Rheumatism Association admitted to the hospital between 1986 and 2001 were studied by means of a retrospective review of their records. Demographically, it was seen that SLE is a disease predominantly of females in their third decade, which is consistent with worldwide data. The mean age of presentation was 31 years (range 14-76) and the mean duration of follow up was 34 (4-179) months. Generally, there was less cutaneous (46%), arthritic (38%), serositis (22%) and renal involvement (33%) but more neuropsychiatric symptoms (26%) in our population. Eighty-six percent of patients were ANA positive, whereas anti dsDNA was positive in 74% of patients. Infections, renal involvement, seizures and thrombocytopenia were associated with poor prognosis (P, 0.05). This study is the first of its kind in Pakistan. The clinical and laboratory characteristics of SLE patients in our study place our population in the middle of a spectrum between the Caucasians and other Asian populations. It has shown that the clinical characteristics of SLE patients in this country may be different to those of its neighbors.

BACKGROUND Few epidemiological studies of systemic lupus erythematosus (SLE) have been conducted in Australia, and current management practice and levels of unmet need in this country are not well characterised. AIM To perform a systematic literature review to identify Australia-specific information on SLE, particularly areas of unmet need. METHODS MEDLINE, EMBASE and the Cochrane Library were searched (1 January 1990 to 29 November 2013). All articles on prevalence, disease characteristics, management and outcomes of SLE in Australia were included. RESULTS There is limited published information on SLE in Australia. Of 24 articles included, 18 described results from observational studies, three were narrative reviews, one was a clinical update, and two were medical education articles. In remote regions, SLE was reported to be more prevalent in Aboriginal Australians than non-Aboriginal Australians; information in urban populations is lacking. Asian Australians may be more affected by SLE than non-Asian Australians. Pregnancy outcomes may also be adversely affected. Many Australians with SLE may experience high levels of unmet need, including delayed diagnosis, ongoing symptoms, flares, depression/anxiety, sleeping difficulty and decreased quality of life. Published guidance on the SLE management in Australia is limited and dated. CONCLUSIONS Published information on SLE in Australia is limited, but suggests that ethnicity may affect the prevalence and disease characteristics and that many Australians with SLE have unmet needs. Improvements in diagnosis, treatment and management are needed to alleviate these needs. Up-to-date guidance on the management of SLE would benefit healthcare professionals and patients.

Abstract
OBJECTIVES We investigated whether systemic lupus erythematosus (SLE) patients could be distinguished based on the time of disease onset and, if so, whether the groups differed in their clinical and laboratory features in ethnically homogeneous Korean patients. METHODS We enrolled 201 SLE patients with available clinical data at the time of onset of SLE from the lupus cohort at Chonnam National University Hospital. Sociodemographic, clinical, and laboratory data, including autoantibodies, and concomitant diseases were found at the time of diagnosis of SLE by reviewing patient charts. We divided SLE patients according to age at SLE diagnosis into three groups: juvenile-onset SLE (JSLE, diagnosed at ≤ 18 years), adult-onset SLE (ASLE, diagnosed at 19-50 years), and late-onset SLE (LSLE, diagnosed at >50 years), and compared baseline demographic, clinical, and relevant laboratory findings. RESULTS Of the 201 patients, 27 (14.4%), 149 (74.1%), and 25 (12.4%) were JSLE, ASLE, and LSLE patients, respectively. Fever, oral ulcers, nephritis, anemia, and thrombocytopenia were more common in JSLE patients than ASLE or LSLE patients (p < 0.05, < 0.05, 0.001, < 0.05, and < 0.05, respectively). However, Sjögren's syndrome was more frequent in LSLE patients than JSLE or ASLE patients (p < 0.05). Disease activity was significantly higher in JSLE patients than in ASLE or LSLE patients (p < 0.001). Anti-dsDNA and anti-nucleosome antibodies were found more frequently in JSLE patients and less frequently in LSLE patients (p < 0.05 and 0.005, respectively) and decreased complement levels were more common in JSLE patients and less common in LSLE patients (p < 0.001, 0.001, and < 0.05, respectively). CONCLUSIONS Our results indicate that SLE patients present with different clinical and serological manifestations according to age at disease onset. JSLE patients have more severe disease activity and more frequent renal involvement and LSLE patients have milder disease activity, more commonly accompanied by Sjögren's syndrome, at disease onset.

Abstract
AIM The purpose of this study was to gain a better understanding of systemic lupus erythematosus (SLE) in Hakka populations. METHODS We studied the demographic, clinical and laboratory characteristics in a cohort of 552 SLE patients diagnosed at the Rheumatology Department in MeiZhou People's Hospital from January 2008 to December 2012. There were 495 women and 57 men (8.7 : 1) with a mean age of 35.3 years (range 12-78 years). The mean age at disease onset and the mean disease duration were 31.8 ± 14.4 years and 3.3 ± 2.8 years, respectively. RESULTS The most common clinical manifestations were arthritis (61.6%), followed by malar rash (52.7%), photosensitivity (22.8%), mouth ulcers (17.0%) and discoid lupus (14.7%). The prevalence was 46.7% for nephritis (by biopsy), 18.3% for pleuritis, 15.6% for pericarditis and 4.9% for neuropsychiatric manifestations. The most common hematological manifestations were anemia (63.8%), followed by leucopenia (29.0%) and thrombocytopenia (14.9%). Antinuclear antibodies were detected in 99.8% of patients, followed by anti-double-stranded DNA (81.3%), anti-SSA (Sjögren's syndrome antigen A)/Ro (58.7%), anti-ribonucleoprotein (36.8%), anti-Sm (35.7%), and anti-SSB/La (15.0%). Anti-cardiolipin immunoglobulin G (IgG) and IgM were detected in 18.3% and 14.1% of patients, respectively. Active disease and infections were the two major causes of death. CONCLUSION The clinical and immunological characteristics of the SLE patients in our study place our population in the middle of the spectrum between other Asian and Caucasian populations.

Abstract
AIM To describe the clinical manifestations, disease activity and organ damage in Korean patients with systemic lupus erythematosus (SLE). METHOD American College of Rheumatology (ACR) criteria, SLE Disease Activity Index (SLEDAI), and Systemic Lupus International Collaborating Clinics/ACR damage index (SDI) were assessed in patients with SLE from 1998 to 2012. RESULTS A total of 996 SLE patients were analyzed. The common accrual of ACR criteria included: immunologic (93%), hematologic (93%), arthritic (66%) and nephritic (50%). In the inception cohort over 10 years of follow-up (n = 120), the number of ACR criteria increased significantly (5.0 ± 1.2 to 5.7 ± 1.3), and nephritis, serositis and neuropsychiatric symptoms tended to increase continuously over time. SLEDAI-2K decreased significantly (5.6 ± 3.4 to 4.1 ± 1.2), but the percentage of patients with SLEDAI scores ≥ 12 did not decrease over time. The common organ damages were musculoskeletal (14.9%) and renal (11.1%). The mean SDI score increased significantly (0.4 ± 0.8 to 1.1 ± 1.6) and renal damage had two peaks in 1 and 6-10 years, musculoskeletal and neuropsychiatric damage were predominant from 1 to 5 years, and ophthalmic damage increased sharply over 10 years. CONCLUSION Compared to other Asian cohorts, disease activity was lower and organ damage was less in our Korean cohort. Nephritis, serositis and neuropsychiatric symptoms increased continuously over time. Overall disease activity decreased significantly, but a small portion of severe disease activity continued during the disease course. The most common organ damage was musculoskeletal. The time in organ damage development varied, which reflects the possible causality, such as disease itself and/or treatment.

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.

Abstract
Systemic lupus erythematosus (SLE) is characterized by multisystem immune-mediated injury in the setting of autoimmunity to nuclear antigens. The clinical heterogeneity of SLE, the absence of universally agreed clinical trial end points, and the paucity of validated therapeutic targets have, historically, contributed to a lack of novel treatments for SLE. However, in 2011, a therapeutic monoclonal antibody that neutralizes the cytokine TNF ligand superfamily member 13B (also known as B-cell-activating factor of the TNF family [BAFF]), belimumab, became the first targeted therapy for SLE to have efficacy in a randomized clinical trial. Because of its specificity, the efficacy of belimumab provides an opportunity to increase understanding of SLE pathophysiology. Although belimumab depletes B cells, this effect is not as powerful as that of other B-cell-directed therapies that have not been proven efficacious in randomized clinical trials. In this article, therefore, we review results suggesting that neutralizing BAFF can have effects on the immune system other than depletion of B cells. We also identify aspects of the BAFF system for which data in relation to SLE are still missing, and we suggest studies to investigate the pathogenesis of SLE and ways to refine anti-BAFF therapies. The role of a related cytokine, TNF ligand superfamily member 13 (also known as a proliferation-inducing ligand [APRIL]) in SLE is much less well understood, and hence this review focuses on BAFF.

Abstract
Ethnic differences in both disease susceptibility and expression have been noted in systemic lupus erythematosus (SLE). This review focuses on the evidence of disparities between SLE patients of Asian and Caucasian descent, the two predominant ethnic groups affected by SLE in the Australian context. While epidemiological studies suggest higher rates of SLE among Asian patients, multi-ethnic cohort studies have allowed direct comparison of disease characteristics between different ethnic groups. Such studies suggest that Asians are affected by more severe SLE across several disease parameters, including increased renal involvement, autoantibody positivity, disease activity and damage accumulation. As delineation of these disparities becomes clearer, uncovering the biological basis of such differences poses a significant opportunity to progress understanding of SLE pathogenesis. Understanding ethnic variation in disease provides a platform for an individualised approach to risk assessment, monitoring and management of SLE.

Abstract
OBJECTIVE To evaluate the clinical characteristics of lupus mesenteric vasculitis (LMV) and identify the potential factors and appropriate treatments that are associated with disease relapse and prognosis in LMV. METHODS A retrospective cohort study was performed among patients admitted to the First Affiliated Hospital of Sun Yet-sen University between 2002 and 2011. Demographic information, clinical symptoms, laboratory findings, imaging characteristics like abdominal CT scan, ultrasonography, medications including corticosteroid, cyclophosphamide, and other immunosuppressive agents, and outcomes were documented. The endpoints of the study were defined as occurrence of severe complications that needed surgical intervention, disease recurrence, or death. RESULTS Out of 3823 systemic lupus erythematosus (SLE) patients, 97 were diagnosed with mesenteric vasculitis with the overall prevalence of 2.5%. Among these 97 LMV patients, 13 died because of serious complications (13/97, 13.4%) and 2 presented intestinal perforation during the induction therapy stage. The logistic regression multivariate analysis indicated that leukopenia [peripheral WBC, odds ratio (OR) = 0.640, 95% confidence interval (CI): 0.456-0.896, P = 0.009], hypoalbuminemia (serum albumin, OR = 0.891, 95% CI: 0.798-0.994, P = 0.039) and elevated serum amylase (OR = 7.719, 95% CI: 1.795-33.185, P = 0.006) were positively associated with the occurrence of serious complications, while intravenous cyclophosphamide (CYC) therapy inhibited the occurrence of serious complications (OR = 0.220, 95% CI: 0.053-0.903, P = 0.036). A total of 79 patients who achieved remission were followed-up for 2-96 months and 18 cases experienced disease relapse (18/79, 22.8%). The statistical analysis adjusted by Cox proportional hazards models indicated that high-dose CYC therapy (≥ 1.0 g/m(2)/month) was a protective factor for disease relapse and led to better outcomes [hazard ratio (HR) = 0.209, 95% CI: 0.049-0.887, P = 0.034], while the severe thickness of the bowel wall (>8mm) was a risk factor (HR = 7.308, 95% CI: 1.740-30.696, P = 0.007). LMV and lupus cystitis occurred concurrently in 22 (22/97, 22.7%) patients, and the symptoms of urinary tract resolved after treatment with corticosteroid and immunosupressants. CONCLUSION LMV is one of the serious complications of SLE with high mortality. The current study demonstrated that leukopenia, hypoalbuminemia, and elevated serum amylase were associated with severe adverse events, while CYC therapy led to better outcomes during remission-induction stage. Severe thickness of the bowel was a risk factor while high-dose CYC therapy was a protective factor for disease relapse in intensification therapy stage. It is necessary to evaluate the urinary tract involvement once LMV is diagnosed due to the frequent coexistence of these 2 diseases.

Abstract
The Chinese systemic lupus erythematosus (SLE) treatment and research group (CSTAR) provides major clinical characteristics of SLE in China and establishes a platform to provide resources for future basic and clinical studies. CSTAR originated as a multicentre, consecutive, and prospective design. The data were collected online from 104 rheumatology centers, which covered 30 provinces in China. The registered patients were required to meet four or more of the American College of Rheumatology (ACR) criteria for the classification of SLE. All CSTAR centers use the same protocol-directed methods to provide uniform evaluations, which included demographic data, clinical features, laboratory examinations, and disease activity evaluations. The patient samples, including DNA samples and sera, were also collected for further quality controls and additional studies. Preliminary analysis from 2104 baseline evaluations was available for this analysis. Of 1914 female and 190 male patients (F:M=10.1), the mean age at onset was 29.2 y with confirmed diagnosis one year later at the age of 30.3 y. Eighty four (4.2%) of 2002 patients had a family history of rheumatic diseases, including 34 (1.7%) cases with SLE. In addition, one hundred and seven (5.2%) abnormal pregnancies were recorded among 2026 experiences. The characteristics of the CSTAR cohort were compared to similarly sized cohorts from other studies. We found that 56.1% of patients presented with concurrent hematological disorders compared to only 18.2% of European patients. Moreover, 47.4% of patients presented with nephropathy compared to 27.9% of European patients. Conversely, neurological manifestations were only seen in 4.8% of Chinese SLE patients compared to 19.4% of European patients, 12.1% of U.S. patients, 22.8% of Malaysian patients and 26.4% of Latin Americans. Pulmonary arterial hypertension and interstitial lung diseases were complications identified in 3.8% and 4.2% of Chinese lupus patients, respectively. The CSTAR registry has provided epidemiological data and phenotypes of Chinese patients with SLE, and has demonstrated several differences between ethnicities. Clinical data and biologic samples would be valuable resources for future translational studies with national and international collaboration.

OBJECTIVE Systemic lupus erythematosus (SLE), an autoimmune condition with diverse clinical manifestations, is reported to have different expression in populations of different ancestry. Most previous studies compared patients of different ethnic groups from geographically distinct cohorts. In our study, we aimed to characterize disease manifestations in patients of different ethnic groups from a single centre, and studied patterns of disease activity over time. METHODS Demographics, baseline disease characteristics and autoantibody profiles, and disease activity (SLEDAI) measured at each visit, were captured from all consenting patients prospectively followed between 2007 and 2011 in an urban teaching hospital lupus clinic. Ethnicity was self-reported. RESULTS Asian ethnicity was significantly associated with more clinically severe SLE. Time-adjusted mean SLEDAI (p = 0.01) and maximum SLEDAI (p = 0.0018) were significantly higher in Asian patients. Asians were more likely to have renal disease (OR 2.9, 95% CI 1.4-5.98; p = 0.004) and persistently active disease (PAD) (OR 2.14, 95% CI 1.05-4.38, p = 0.04). Asian lupus patients also had a significantly higher proportion of autoantibody positivity to anti-dsDNA, anti-RNP, anti-Sm, anti-Ro and anti-La, as well as increased likelihood of hypocomplementaemia and immunosuppressant use. CONCLUSION In this single-cohort study, Asian ethnicity was found to be associated with increased SLE disease activity. This suggests significant inter-ethnic genetic contributions to the regulation of autoimmune responses and disease severity in SLE.

Abstract
INTRODUCTION The objective of this study is to determine whether serum concentrations of B cell activating factor from the tumour necrosis factor family (BAFF) and/or a proliferation-inducing ligand (APRIL) are associated with clinical manifestations of systemic lupus erythematosus (SLE). METHODS BAFF and APRIL concentrations were quantified using a commercial ELISA in serum samples obtained at the time of clinical assessment in 98 patients, and on 245 samples from 75 of these patients followed prospectively. RESULTS Serum BAFF was significantly increased, and APRIL decreased, in patients with either renal or central nervous system (CNS) lupus. In contrast, in cross-sectional analysis, there was no correlation between disease activity (SLEDAI-2k) and serum BAFF or APRIL. In longitudinal follow-up, there was no association between changes in serum BAFF or APRIL and changes in SLEDAI-2k, or between baseline serum BAFF or APRIL and subsequent changes in SLEDAI-2k. However, between-visit changes in BAFF were significantly different in patients with increases in SLEDAI-2k ≥ 4, compared to patients whose SLEDAI-2k did not change. CONCLUSIONS Although neither serum BAFF nor APRIL correlated with disease activity in the overall population, elevated serum BAFF and reduced APRIL may be markers of renal and CNS disease in SLE patients.

Abstract
Objectives Ethnic differences in systemic lupus erythematosus (SLE) have been previously described in the multiethnic Malaysian population. However, there have since been many demographic and socioeconomic changes in the country. The aim of this study is to re-examine the clinical and immunological profiles of Malaysian SLE patients of different ethnic backgrounds. Methods Consecutive follow-up patients at the University Malaya Medical Centre (UMMC) from July 2010 until March 2011 were included in the study. Results The most common clinical manifestations were malar rash (61.3%), arthritis (52.3%), haematological disease (51.6%), oral ulcers (51%) and renal disease (40.6%). Ethnic Indians had fewer malar and discoid rashes but were at higher risk of arthritis, serositis, renal and neuropsychiatric disease compared to Malays and Chinese Malaysians. Antiphospholipid syndrome (APS) was less common in Chinese. A longer duration of SLE correlated with a lower SLEDAI score. Conclusion Overall, the spectrum disease expression was similar to the earlier Malaysian study but the frequency of the more severe disease manifestations, viz. renal, haematological, neuropsychiatric involvements and serositis, were lower. This study further emphasises differences primarily between ethnic Indians and the other races in Malaysia.

Abstract
OBJECTIVE Systemic lupus erythematosus (SLE), a chronic multisystem autoimmune disease with a wide spectrum of manifestations, shows considerable variation across the globe, although there is little evidence to indicate its relative prevalence in Asia. This review describes its prevalence, severity, and outcome across countries in the Asia-Pacific region. METHODS We conducted a systematic literature search using 3 groups of terms (SLE, epidemiology, and Asia-Pacific countries) of EMBase and PubMed databases and non-English language resources, including Chinese Wanfang, Korean KMbase, Korean College of Rheumatology, Japana Centra Revuo Medicina, Taiwan National Digital Library of Theses and Dissertations, and Taiwanese, Thai, and Vietnamese journals. RESULTS The review showed considerable variation in SLE burden and survival rates across Asia-Pacific countries. Overall crude incidence rates (per 100,000 per year) ranged from 0.9-3.1, while crude prevalence rates ranged from 4.3-45.3 (per 100,000). Higher rates of renal involvement, one of the main systems involved at death, were observed for Asians (21-65% at diagnosis and 40-82% over time) than for whites. While infections and active SLE were leading causes of death, a substantial proportion (6-40%) of deaths was due to cardiovascular involvement. The correlation between the Human Development Index and 5-year survival was 0.83. CONCLUSION This review highlights the need to closely monitor Asian SLE patients in Asian countries for renal and cardiovascular involvement, especially those who may not receive proper treatment and are therefore at greater risk of severe disease. We hope this will encourage further research specific to this region and lead to improved clinical management.

Abstract
The availability of population-specific normative data regarding disease severity measures is essential for patient assessment. The goals of the current study were to characterize the pattern of ankylosing spondylitis (AS) in Portuguese patients and to develop reference centile charts for BASDAI, BASFI, BASMI and mSASSS, the most widely used assessment tools in AS. AS cases were recruited from hospital outpatient clinics, with AS defined according to the modified New York criteria. Demographic and clinical data were recorded. All radiographs were evaluated by two independent experienced readers. Centile charts for BASDAI, BASFI, BASMI and mSASSS were constructed for both genders, using generalized linear models and regression models with duration of disease as independent variable. A total of 369 patients (62.3% male, mean ± (SD) age 45.4 ± 13.2 years, mean ± (SD) disease duration 11.4 ± 10.5 years, 70.7% B27-positive) were included. Family history of AS in a first-degree relative was reported in 17.6% of the cases. Regarding clinical disease pattern, at the time of assessment 42.3% had axial disease, 2.4% peripheral disease, 40.9% mixed disease and 7.1% isolated enthesopatic disease. Anterior uveitis (33.6%) was the most common extra-articular manifestation. The centile charts suggest that females reported greater disease activity and more functional impairment than males but had lower BASMI and mSASSS scores. Data collected through this study provided a demographic and clinical profile of patients with AS in Portugal. The development of centile charts constitutes a useful tool to assess the change of disease pattern over time and in response to therapeutic interventions.

Abstract
The predisposition to and clinical phenotype of systemic lupus erythematosus, an autoimmune disease that is associated with significant morbidity and mortality, are affected by genetic and environmental factors. This article aims to examine whether Asians have worse lupus by reviewing the literature on genetic predisposition and clinical outcomes, including major organ involvement, damage score and mortality in Asian populations compared with other ethnicities. A number of lupus nephritis susceptibility genes have been identified in Asians and White patients, with further variations among different Asian populations. Meta-analysis studies on various Fcγ receptor subtypes revealed that FcγRIIIA-F158 allele, which is associated with low binding affinity to IgG1 and IgG3, predisposed to lupus nephritis in Asian patients. Asian patients were reported to have higher rates of lupus nephritis-associated autoantibodies, lupus nephritis and more active glomerulonephritis compared with White patients. Renal outcome and the level of immunosuppressant use in Asians were comparable to Afro-American Blacks in some studies. Asians were also found to have higher overall damage scores compared with Whites. The difference in mortality between Asian patients and other ethnicities in different geographical regions was found to vary depending on socioeconomic factors such as access to health care. Poverty, education level, cultural and behavioural factors are confounders to ethnicity in determining clinical outcome of systemic lupus erythematosus.

Abstract
Ethnic variation in the frequency and outcome of systemic lupus erythematosus (SLE) has been recognized for decades. The reasons underlying these discrepancies are not completely understood but it is most likely that both genetic and nongenetic factors are responsible for them. Sorting out the extent to which these factors, particularly those of a nongenetic nature, exert their influence in SLE is not easy given inherent methodological difficulties in studying them. To establish this review properly, we would like to make it clear from the outset that ethnicity is a broad construct that implies not only biological but also nonbiological features including cultural and sociodemographic, among others. We will then describe the epidemiological differences of SLE among Caucasian and non-Caucasian populations followed by a succinct review of the genetic predisposition to SLE with special emphasis in ethnic heterogeneity. Differences in disease activity, lupus nephritis, damage and mortality as a function of ethnic group will then be described. Finally, we will present a comprehensive model of the influence of ethnicity on SLE.

Abstract
We performed a retrospective study of 10 patients with refractory systemic lupus erythematosus treated with rituximab to determine the efficacy, safety and impact on hospitalization days. Patients received rituximab according to a standardized protocol, all achieved B-cell depletion with clinical improvement in nine patients. At 12 months, BILAG scores improved significantly from a median of 13.5 (range 3-20) at baseline to 1 (range 0-27) (p < 0.05). There was significant reduction in urinary total protein excretion with stabilization of renal function in patients with nephritis. Two out of three patients with thrombocytopenia had normalization of platelet counts. The median duration of B-cell depletion was 6 months (range 6-18). Two patients required retreatment and responded well. There were no adverse outcomes following rituximab therapy. Patients with lupus nephritis spent a median of 17.1 days per year (range 1.9-49) in hospital on conventional treatment which was reduced to 0 days (range 0-14.8, p = 0.027) post-rituximab treatment. The cost of hospitalization was 5989 Singapore dollars per patient-year while on conventional treatment and 5792 Singapore dollars per patient-year post-rituximab. This study adds to the growing literature of rituximab efficacy with potential cost saving in lupus nephritis.

Abstract
The aim of this study was to describe the presenting clinical manifestations and syndromes of Filipino patients on diagnosis of systemic lupus erythematosus (SLE). We performed a retrospective review of medical records of Filipino SLE patients included in the lupus database of the University of Santo Tomas (UST) in Manila, Philippines. All patients fulfilled the American College of Rheumatology criteria for SLE. The following data were recorded: (1) demographic profile, (2) clinical manifestations on SLE diagnosis, and (3) clinical syndromes prior to and during fulfillment of diagnostic criteria for SLE and disease interval from diagnosis of a clinical syndrome to SLE diagnosis. Clinical data of 1,070 patients entered into the UST lupus database as of October 2005 were analyzed. The average age at SLE diagnosis was 28.5 +/- 11.5 (range 5-71) years, with 1,025 female and 45 male subjects. The most common presenting manifestation was arthritis (68%), followed by malar rash (49%), renal involvement (47%), photosensitivity (33%), and oral ulcers (33%). The following clinical syndromes were recorded prior to or during SLE diagnosis: nephrotic syndrome (30%), undifferentiated connective tissue disease (UCTD) (22%), autoimmune hemolytic anemia (AIHA) (6%), and idiopathic thrombocytopenic purpura (ITP) (6%). Among these, AIHA preceded the diagnosis of SLE at the longest interval (20.3 +/- 30.6, range 1-194 months). In this large database of Filipino patients with SLE, the most common presenting manifestation was arthritis, with renal involvement occurring in almost 50%. Among the clinical syndromes, nephrotic syndrome was the most common, whereas AIHA recorded the longest interval preceding SLE diagnosis, at an average of 20.3 months. Our findings are similar to data from other countries and emphasize the broad range of manifestations of SLE. The findings also reinforce the need to establish and maintain SLE databases to enhance awareness, early diagnosis, and more efficient management of the disease.

Abstract
Abstract Clinical features of systemic lupus erythematosus (SLE) have been described from different geographical regions in the world. However, data from many Middle East countries, including Iran, are scarce. This study aims to demonstrate the demographic, clinical, and laboratory characteristics in Iranian patients with SLE. In this prospective study, all the patients referring to Shiraz educational hospitals (Nemazi–Hafez) with SLE (American College of Rheumatology criteria) during a 5-year period (2001 to 2006) were included. A complete history was taken; physical examination and routine hematological, serological, and immunological tests were done for each patient. There were 356 women and 54 men with an average age of 30.27 years at the onset of disease. Of the patients, 78% had hematological abnormalities, 65.5% had articular involvement, 54.5% had photosensitivity, and 60.5% had malar rash. Serositis occurred in 38% of patients of whom 12% had pericarditis and 26% had pleuritis. Nephritis was diagnosed in 48% of the cases and consisted always of glomerular nephritis. Biopsy-proven lupus nephritis was in most cases class IV(49.7% of all the biopsies). Oral ulcers were observed in 28% of patients. Neuropsychiatric manifestations, gastrointestinal involvement, and lymphadenopathy were observed in 31.5%, 8.3%, and 14.2% of patients, respectively. In all, 93% of patients were positive for antinuclear antibodies, whereas antidouble-stranded DNA was positive in 83% of patients. Coomb’s positive hemolytic anemia appeared in 12.4% of the cases. Rheumatoid factor was detected in 9.7% of patients, and lupus erythematosus cell was seen in 32.5% of them. In all, 196 (47.8%) patients represented hypocomplementemia. Regarding hematological manifestations, 74.5% had microcytic hypochromic anemia, 64.6% had leukopenia, and 44.6% had thrombocytopenia; 18 (4.4%) patients died during the study period of which eight (2%) died because of cardiopulmonary involvement. Generally, there was more cutaneous, serositis, and neuropsychiatric involvement in our population than other Middle East countries. Serositis was associated with poorer prognosis, and the pattern of disease in these patients was much more sever than patients without serositis ( P = 0.001). This is the first study of its kind in Iran. More multicenter studies should be undertaken in Iran to describe the pattern of SLE.

Abstract
OBJECTIVES To investigate the association of a non-synonymous single-nucleotide polymorphism (SNP) in DNASEI with susceptibility to systemic lupus erythematosus (SLE) and the production of autoantibodies to nuclear antigens. METHODS The Gln244Arg (rs1053874) SNP was studied in 276 SLE patients and in 368 healthy controls of Spanish ancestry. Its relationship with SLE susceptibility, serum DNase I activity, anti-ribonucleoprotein (RNP), anti-double-stranded DNA (dsDNA), anti-nucleosome and anti-single-stranded DNA (ssDNA) antibodies was determined. RESULTS An association of the Gln244Arg SNP with SLE susceptibility that followed a recessive genetic model (P=0.002) was found. The GG genotype was more common in SLE patients (59.8%) than in controls (47.3%). However, the Gln244Arg genotype did not correlate with DNase I activity in sera from SLE patients or from controls. In addition, the Gln244Arg SNP did not influence autoantibody titres significantly. CONCLUSION The association of the Gln244Arg SNP with SLE susceptibility indicates that common polymorphisms in DNASEI play a role in the genetics of SLE. However, the lack of effect of the Gln244Arg SNP on serum DNase I activity calls into question the direct involvement of this specific SNP.
