Abstract
This study aims to examine the prevalence and outcomes of end-stage kidney disease (ESKD) among systemic lupus erythematosus (SLE) patients. SLE patients identified from the national administrative datasets were linked to the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA) to identify the ESKD cases. Period prevalence of ESKD among SLE patients was calculated. The risk of developing ESKD by ethnicity was explored with Cox Proportional Hazards model. The adjusted hazard ratio (HR) of all-cause mortality for Māori, Pacific, Asian compared to European/others was estimated. Of the 2837 SLE patients, 210 (7.4%) developed ESKD. The average period prevalence of ESKD among SLE patients was 5.7%. Men had twice the prevalence rate of ESKD than women (10.0% vs 5.2%). Māori and Pacific had higher prevalence rate than Asian and European/others (9.4%, 9.8% vs 4.4% and 3.8%). The adjusted HR of developing ESKD for men compared to women was 3.37 (95% CI 1.62-7.02). The adjusted HR of developing ESKD for Māori and Pacific compared to European/others was 4.63 (95% CI 1.61-13.29) and 4.66 (95% CI 1.67-13.00), respectively. Compared to European/others, Māori had an HR of 2.17 (95% CI 1.18-4.00) for all-cause mortality. SLE patients had a high prevalence rate of ESKD. Men, Māori, and Pacific patients with SLE were more likely to develop ESKD. Māori patients with ESKD had poorer survival than other patients. Interventions are needed to reduce the risk of ESKD and to improve the survival of ESKD patients for the disadvantaged groups.

Abstract
OBJECTIVES This study aims to provide updated data on the incidence and prevalence of systemic lupus erythematosus (SLE) in New Zealand and to examine the difference between ethnic groups. METHODS We identified the SLE cases from the national administrative datasets. The date of first identification of SLE was the earliest date of a related inpatient event or the earliest date of a related outpatient event. The crude incidence and prevalence of SLE in 2010-2021 were estimated by gender, age group and ethnicity. The WHO (World Health Organization) age-standardised rate (ASR) of incidence and prevalence of SLE was calculated, after stratifying the cases by ethnicity and gender. RESULTS The average ASR of incidence and prevalence of SLE in 2010-2021 was 2.1 and 42.1 per 100,000 people in New Zealand. The average ASR of incidence for women was 3.4 per 100,000 for women and 0.6 for men. It was highest for Pacific women (9.8), followed by Asian women (5.3) and Māori women (3.6), and was lowest for Europeans/Others (2.1). The average ASR of prevalence was 65.2 per 100,000 for women and 8.5 for men. It was highest for Pacific women (176.2), followed by Māori women (83.7) and Asian women (72.2), and was lowest for Europeans/Others (48.5). The ASR of prevalence of SLE has been increasing slightly over time: from 60.2 in 2010 to 66.1 per 100,000 in 2021 for women and from 7.6 in 2010 to 8.8 per 100,000 in 2021 for men. CONCLUSION The incidence and prevalence of SLE in New Zealand were comparable to the rates in European countries. Pacific people had the highest incidence and prevalence of SLE, more than three times the rates for Europeans/others. The high incidence of SLE in Māori and Asian people also has implications for the future as these populations increase as a proportion to the total population.

Abstract
We conducted a retrospective study to determine the incidence and frequency of different subtypes of encephalitis in patients aged 15 and older in the Auckland and Northland regions of New Zealand between 2009 and 2018. Residents in Auckland and Northland presenting with encephalitis between 2009 and 2018 were identified from three overlapping databases: positive cerebrospinal fluid (CSF) viral polymerase chain reaction (PCR) tests, CSF neuronal antibody requests, and CSF neuronal antibody tests sent overseas. A diagnosis of autoimmune encephalitis required fulfilment of diagnostic criteria published by Graus and colleagues (2016). One hundred and thirty-six (69, 50.7% female) patients met study inclusion criteria. The median age was 59 (range 15-92). The annual incidence was 1.10 cases per 100,000 person-years. Of these 136 patients, 56 (41.2%) had an infectious aetiology, with varicella zoster (26, 46.4%) and herpes simplex (23, 41.1%) being the most common agents. Autoimmune encephalitis was diagnosed in 32 patients (23.5%). LGI-1 antibody was the most commonly identified neuronal autoantibody (10 patients, 13.2%). Forty-eight patients (35.3%) had encephalitis of unknown cause. In-hospital mortality for infectious encephalitis was 12.5%, autoimmune encephalitis 6.3%, and encephalitis of unknown cause 10.4%. Compared to a previous analysis of encephalitis in adults in Auckland, the incidence of encephalitis and autoimmune encephalitis had increased. The proportion of patients with an unknown cause for encephalitis had decreased.

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.

Retrospective review of the clinical and laboratory data in silent lupus nephritis. Int Urol Nephrol 2021; 54:1933-1938.

Abstract
PURPOSE To determine the ratio of renal disease necessitating immunosuppressive treatment in lupus patients who are clinically asymptomatic by means of renal disease. It was also examined whether silent lupus nephritis is associated with any of the non-renal clinical findings. METHODS All kidney biopsies performed in lupus patients between 1990 and 2009 at the Rheumatology Department of Ege University Faculty of Medicine were retrospectively screened. Among the 258 kidney biopsies screened, 54 had no clinical renal findings but had active disease together with anti-dsDNA positivity and/or hypocomplementemia. Patients were classified into two groups who require and do not require immunosuppressive therapy according to their final pathological results at biopsy. The frequency of serious renal involvement in the sample was calculated. Then subgroups were compared with each other in terms of the clinical and laboratory features using Statistical Package for Social Sciences version 13 software. RESULTS Thirteen of the 54 patients (24%) had severe renal involvement requiring immunosuppressant therapy. When the groups were compared to each other, it was found that serositis and hematologic involvement were significantly more frequent in patients who needed immunosuppressive treatment (42.9% versus 10.0%; p = 0.003 and 64.3% versus 37.5; p = 0.039). CONCLUSION Even in the absence of clinical renal manifestations, active patients at high risk of renal disease such as hypocomplementemia, anti-ds DNA positivity may have severe renal disease requiring immunosuppressive treatment. Thus, renal biopsy indications in lupus patients should better be revaluated.

Abstract
OBJECTIVES To assess the safety and effectiveness of mycophenolate mofetil (MMF) in Japanese adults with lupus nephritis (LN) in real-world clinical practice. METHODS This multicentre, prospective, post-marketing surveillance study investigated the effectiveness and safety of MMF, as induction or maintenance therapy, in LN patients. Primary endpoints were adverse drug reactions (ADRs), changes in renal function from baseline, and relapse rate (RR) after 6 months in the maintenance group, estimated using the Kaplan-Meier method. Complete remission (CR) and partial remission (PR) were estimated by renal measurements. RESULTS Overall, 112 patients were enrolled in the induction group and 340 in the maintenance group. Of these 452 patients, 418 were evaluable for safety and 396 for effectiveness. Eighty-three patients (19.85%) experienced ADRs, most commonly herpes zoster (3.34%) and diarrhoea (3.11%). Serious ADRs occurring in more than three patients were cytomegalovirus infections (1.43%), acute pyelonephritis (0.71%), and herpes zoster (0.71%). One patient died from herpes zoster disseminated. CR and PR were 19.54% and 44.82%, respectively, in the induction group, and 40.62% and 66.16%, respectively, in the maintenance group. RR in the maintenance group was 0.70%. CONCLUSIONS The tolerability of MMF is in line with that reported in other studies. Since the average dose of MMF was <1.5 g/day, research into the optimal dose for achieving effectiveness is required.

Abstract
Systemic lupus erythematosus is the most characteristic of auto-immune disorders that can lead to tissue damage in many organs, including kidney. Lupus nephritis occurs in 10 to 40% of lupus patients. Its clinical hallmark is the appearance of a proteinuria as soon as a 0.5 g/g or 0.5 g/d threshold, which calls for a renal histological evaluation in order to determine the lupus nephritis severity and the need for specific therapy. More than half of renal biopsies lead to the diagnosis of active lupus nephritis-class III or class IV A according to the ISN/RPS classification-that are the most severe in regards to renal prognosis and mortality. Their treatment aims to their clinical remission and to the prevention of relapse with minimal adverse effects for eventually the preservation of renal function, the prevention of other irreversible damage, and the reduction of risk of death. The remission is obtained through induction therapies of which the association of high dose steroids and cyclophosphamide is the most experienced. When this association must be challenged by the prevention of side-effect, in particular infertility, mycophenolate can be given instead of cyclophosphamide. Maintenance therapy, for the prevention of relapse, consists in mycophenolate or in azathioprine, mycophenolate being the most efficient however associated with a high risk of teratogenicity. Withdrawal of maintenance therapy is possible after two to three years in absence of high risk factors of relapse of lupus nephritis, however a reliable assessment of the risk of relapse is still lacking. Only pure membranous lupus nephritis (pure class V) associated with high level proteinuria requires specific therapies that usually associates steroids and an immunosuppressive drug. However, their choice hierarchy and even the use of less immunosuppressive strategies remain to be determined in terms of benefice over risk ratios. In spite of its trigger effect on lupus activity, pregnancy can be safe and successful if scheduled in the lowest risk periods with close multidisciplinary monitoring before, during and after. When necessary, renal replacement therapy does not require specific adaptation, renal transplantation is the best option when possible, as early as possible.

Abstract
BACKGROUND Research adhering to community engagement processes leads to improved outcomes. The level of Indigenous communities' engagement in rheumatology research is unknown. OBJECTIVE To characterize the frequency and level of community engagement reporting in arthritis studies conducted in Australia (AUS), Canada (CAN), New Zealand (NZ) and the United States of America (USA). METHODS Studies identified through systematic reviews on topics of arthritis epidemiology, disease phenotypes and outcomes, health service utilization and mortality in Indigenous populations of AUS, CAN, NZ and USA, were evaluated for their descriptions of community engagement. The level of community engagement during inception, data collection and results interpretation/dissemination stages of research was evaluated using a custom-made instrument, which ranked studies along the community engagement spectrum (i.e. inform-consult-involve-collaborate-empower). Meaningful community engagement was defined as involving, collaborating or empowering communities. Descriptive analyses for community engagement were performed and secondary non-parametric inferential analyses were conducted to evaluate the possible associations between year of publication, origin of the research idea, publication type and region of study; and meaningful community engagement. RESULTS Only 34% (n = 69) of the 205 studies identified reported community engagement at ≥ 1 stage of research. Nearly all studies that engaged communities (99% (n = 68)) did so during data collection, while only 10% (n = 7) did so at the inception of research and 16% (n = 11) described community engagement at the results' interpretation/dissemination stage. Most studies provided community engagement descriptions that were assessed to be at the lower end of the spectrum. At the inception of research stage, 3 studies reported consulting communities, while 42 studies reported community consultation at data collection stage and 4 studies reported informing or consulting communities at the interpretation/dissemination of results stage. Only 4 studies described meaningful community engagement through all stages of the research. Inferential statistics identified that studies with research ideas that originated from the Indigenous communities involved were significantly more associated with achieving meaningful community engagement. CONCLUSIONS The reporting of Indigenous community engagement in published arthritis studies is limited in frequency and is most frequently described at the lower end of the community engagement spectrum. Processes that support meaningful community engagement are to be promoted.

Abstract
Juvenile-onset systemic lupus erythematosus (JSLE) is a rare, heterogeneous multisystem autoimmune disease that can affect any organ, and present with diverse clinical and serological manifestations. Vasculitis can be a feature of JSLE. It more commonly presents as cutaneous vasculitis than visceral vasculitis, which can affect the central nervous system, peripheral nervous system, lungs, gut, kidneys, heart, and large vessels. The incidence and prevalence of vasculitis in JSLE has not been well described to date. Symptoms of vasculitis can be non-specific and overlap with other features of JSLE, requiring careful consideration for the diagnosis to be achieved and promptly treated. Biopsies are often required to make a definitive diagnosis and differentiate JSLE related vasculitis from other manifestations of JSLE, vasculopathies, and JSLE related antiphospholipid syndrome. Visceral vasculitis can be life threatening, and its presence at the time of JSLE diagnosis is associated with permanent organ damage, which further highlights the importance of prompt recognition and treatment. This review will focus on the presentation, diagnosis, management and outcomes of vasculitis in JSLE, highlighting gaps in the current evidence base.

Abstract
Objectives The aim of the present work was to study the clinical characteristics of cutaneous vasculitis (CV) in systemic lupus erythematosus (SLE) patients and find possible potential key players in its development and implicated associations with the disease manifestations. Patients and methods Fifty adult female SLE patients underwent full history taking, thorough clinical examination and laboratory investigations. The SLE Disease Activity Index (SLEDAI) and accumulated damage using the Systemic Lupus International Collaborative Clinics/American College of Rheumatology Damage Index (SLICC/ACR DI) were assessed. Results The mean age of the patients was 29.1 ± 6.1 years and was significantly lower in those with CV ( p = 0.018). The disease duration was 4.9 ± 3.7 years. CV was present in 30% of the patients. Musculoskeletal manifestations and hypocomplementemia were present in all patients with CV. The SLEDAI and SLICC/ACR DI tended to be higher in those with CV. Complement (C3 and C4) was significantly consumed in CV patients ( p < 0.0001). Antiphospholipids were comparable between those with and without CV. Lupus nephritis, cardiovascular manifestations and Sjögren syndrome were significantly linked to the development of CV ( p = 0.025, p = 0.023 and p < 0.0001, respectively). Both C3 and C4 showed a high sensitivity (93.3% and 86.7%) to detect CV in SLE at cut-off values below 81.4 mg/dl and 16.8 mg/dl, respectively. Conclusion CV is closely related to hypocomplementemia but not to antiphospholipids and is associated with lupus nephritis, musculoskeletal manifestations and Sjögren syndrome.

[PMID: 29387436 PMCID: PMC5786908 DOI: 10.1136/lupus-2017-000241] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2017] [Revised: 11/23/2017] [Accepted: 11/27/2017] [Indexed: 11/19/2022]
Abstract
Lupus nephritis (LN) affects up to 50% of patients with Systemic Lupus Erythematosus (SLE) and is associated with a worse prognosis. LN usually develops within the first 5 years of the onset of the disease. We report three patients with very delayed LN (DLN) diagnosed after 15 or more years after SLE diagnosis. The three patients were non-Caucasian women with adolescent or adult-onset SLE. Each had antinuclear, anti-dsDNA and anti-Ro antibodies. Hydroxychloroquine was prescribed for each. Their disease courses were characterised by sporadic non-renal flares controlled by steroids and, in two cases, by one cycle of rituximab. Unexpectedly, they developed proteinuria, haematuria and lowering of estimated glomerular filtration rate with clinical signs of renal disease. LN was confirmed by renal biopsy. Reviewing them, each showed serological signs of increasing disease activity (rising levels of anti-dsDNA antibodies and fall in C3) that predated clinical or laboratory signs of LN by 1–3 years. Reviewing the literature, we found a lack of knowledge about DLN starting more than 15 years after SLE diagnosis. With the increasing life expectancy of patients with SLE it is likely that more cases of very DLN will emerge.

Semin Arthritis Rheum 2017; 47:586-592. [PMID: 28823732 DOI: 10.1016/j.semarthrit.2017.07.009] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2017] [Revised: 07/03/2017] [Accepted: 07/19/2017] [Indexed: 11/18/2022]
Abstract
BACKGROUND Indigenous populations of Canada, America, Australia, and New Zealand have increased rates and severity of rheumatic disease. Our objective was to summarize mortality outcomes and explore disease and social factors related to mortality. METHODS A systematic search was performed in medical (Medline, EMBASE, and CINAHL), Indigenous and conference abstract databases (to June 2015) combining search terms for Indigenous populations and rheumatic diseases. Studies were included if they reported measures of mortality (crude frequency, mortality rate, survival, and potential years of life lost (PYLL)) in Indigenous populations from the four countries. RESULTS Of 5269 titles and abstracts identified, 504 underwent full-text review and 12 were included. No studies from New Zealand were found. In five Canadian studies of systemic lupus erythematosus (SLE) patients, First Nations ethnicity was associated with lower survival after adjusting for disease and social factors, and an increased frequency of death from lupus and its complications compared to Caucasians was found. All-cause mortality was higher in Native Americans (n = 2 studies) relative to Whites with SLE after adjusting for disease and social factors, but not in those with lupus nephritis alone. Australian Aborigines with SLE frequently developed infection and lupus complications leading to death (n = 3 studies). Mortality rates were increased in Pima Indians in the United States with rheumatoid arthritis (RA) compared to those without RA. One study in Native Americans with scleroderma found nearly all deaths were related to progressive disease. CONCLUSIONS Canadian and American Indigenous populations with SLE have increased mortality rates compared to Caucasian populations. Mortality in Canadian and Australian Indigenous populations with SLE, and in Native American populations with RA and scleroderma, is frequently attributed to disease progression or complications. The proportional attribution of rheumatic disease severity and social factors to mortality and complications leading to death between Indigenous and non-Indigenous populations has not been fully evaluated.

Abstract
We performed a systematic review designed to characterize clinical phenotypes and outcomes in Indigenous populations with rheumatic disease to enhance the understanding of how rheumatic disease presents in Indigenous populations and allow for better projection of the healthcare needs of the communities affected. A systematic search was performed in medical (Medline, EMBASE, CINAHL), Indigenous and conference abstract databases (to June 2015). Search terms for Indigenous populations were combined with terms for inflammatory arthritis conditions, connective tissue disorders, crystal arthritis and osteoarthritis. Studies were included if they reported on disease features, disease activity measures, or patient-reported outcomes in Canadian, American, Australian or New Zealand Indigenous populations. Data were extracted in duplicate, and a narrative summary was prepared. A total of 5269 titles and abstracts were reviewed, of which 504 underwent full-text review and 85 met inclusion criteria. Nearly all the studies described outcomes in the North American populations (n = 77), with only four studies from Australia and four studies from New Zealand. The majority of studies were in rheumatoid arthritis (n = 31) and systemic lupus erythematosus (n = 19). Indigenous patients with rheumatoid arthritis had higher disease activity and reported more significant impact on patient-reported outcomes and quality of life than non-Indigenous patients. Spondyloarthropathy features were described in North American populations, with most patients having advanced manifestations. In systemic lupus erythematosus, nephritis was more frequent in Indigenous populations. Gout and osteoarthritis were more severe in New Zealand Maori populations. The existing literature supports differences in disease phenotype and severity in Indigenous populations of Canada, America, Australia and New Zealand. We encourage investigators in this area of research to undertake contemporary studies that disentangle differences between phenotype and severity that are biologic in etiology or merely reflecting differences in access to care and that provide a longitudinal assessment of outcomes in more diverse populations.

Abstract
Increased lupus nephritis has been reported in Pacific Island and Maori populations. Previous studies suggest ethnic variation in response to immunosuppression treatment; however this has not been assessed in Pacific Island and Maori cohorts. This retrospective study reviewed class 3, 4 and 5 lupus nephritis outcomes and response to induction immunosuppression over a 10-year period in a New Zealand multi-ethnic cohort with high Pacific Island representation. This included 49 renal biopsies in 41 patients; by ethnicity Pacific Island 53.7%, Asian 31.7%, Caucasian 12.2%, and New Zealand Maori 2.4%. There were 11 class 3, 24 class 4 and 17 class 5 either alone or in combination with class 3/4. There were no statistically significant differences in renal function or proteinuria between ethnic groups at baseline. Pacific Island class 3/4 showed similar rates of renal remission with intravenous cyclophosphamide (6/8) and mycophenolate (4/7) induction treatment; results were comparable to the overall study group. There were no deaths or permanent dialysis requirements in the first six months of treatment, and no increased risk of adverse outcomes when stratified by ethnicity. Five lupus nephritis relapses occurred during maintenance treatment and there was no apparent ethnicity bias. CONCLUSION Pacific Island people disproportionately present with increased lupus nephritis; and had comparable renal remission rates with intravenous cyclophosphamide and oral mycophenolate which were similar to the whole study cohort.

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
Background The prevalence and variation by ethnicity of cutaneous lupus in New Zealand is not known. Therefore, a cross-sectional study to determine the prevalence and variation by ethnicity of cutaneous lupus in the ethnically diverse community of South Auckland, New Zealand, was undertaken. Methods Multiple sources were examined to determine the prevalence of acute cutaneous lupus erythematosus, subacute cutaneous erythematosus and discoid lupus erythematosus. Ethnicities examined were European, Māori/Pacific and Indian/Asian. Capture-recapture was used to determine the overall population prevalence of cutaneous lupus. Results A total of 145 cases of cutaneous lupus were identified. There were 22 men and 123 women, with an average age (standard deviation), respectively, of 46.4 (±21.5) and 43.1 (±14.8) years. There were 53 cases of acute cutaneous lupus erythematosus, 19 cases of subacute cutaneous erythematosus and 66 cases of discoid lupus erythematosus. The age and sex adjusted relative risk (95% confidence interval; CI) of Māori/Pacific compared to the European population was 2.47 (95% CI 1.67-3.67) for all types of cutaneous lupus, 1.60 (95% CI 0.84-3.18) for acute cutaneous lupus erythematosus, 0.09 (95% CI 0.01-1.1) for subacute cutaneous erythematosus and 5.96 (95% CI 3.06-11.6) for discoid lupus erythematosus. The overall prevalence of cutaneous lupus was 30.1 (95% CI 25.5-35.4) per 100,000. However, capture-recapture estimated the unadjusted prevalence of cutaneous lupus to be 86.0 (95% CI 78.1-94.7) per 100,000. Conclusion Māori and Pacific people in Auckland, New Zealand, have a greater relative risk of all types of cutaneous lupus compared to the European population and a particularly high risk of discoid lupus erythematosus.

Abstract
Socioeconomic status (SES) is a hierarchical social classification associated with different outcomes in health and disease. The most important factors influencing SES are income, educational level, occupational class, social class, and ancestry. These factors are closely related to each other as they present certain dependent interactions. Since there is a need to improve the understanding of the concept of SES and the ways it affects health and disease, we review herein the tools currently available to evaluate SES and its relationship with health and autoimmune diseases.

Abstract
Objectives To describe the incidence, diagnostic clinical manifestations and severity of juvenile systemic lupus erythematosus (jSLE) in a cohort of New Zealand Maori and Pacific Island children compared to European children. Methods A chart review was conducted of children with jSLE seen by the Starship paediatric rheumatology and/or renal services between January 2000 and November 2010. Diagnostic clinical data and lupus nephritis data at anytime were collated while classic British Isles Lupus Assessment Group (BILAG) and Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) scores were derived retrospectively. Results Thirty-two children were diagnosed with jSLE with an annual incidence of 0.52 per 100,000 per year. Compared with European children (0.31 per 100,000 per year) the incidence of jSLE was higher among Maori and Pacific (0.67 per 100,000 per year, p = 0.06) and significantly higher among Asian children (1.17 per 100,000 per year, p = 0.01). Compared with European children, Maori and Pacific children were more frequently diagnosed with lupus nephritis (80% vs 40%, p = 0.09) and severe (WHO class 4 or 5) renal lesions (60% vs 40%, p = 0.43) at presentation. Similarly, at any time during the study, lupus nephritis (100% vs 40%, p = 0.001) and severe (WHO class 4 or 5) renal lesions (73.3% vs 40%, p = 0.12) were more frequent among Maori and Pacific compared with European children. Furthermore, retrospective BILAG assessment of diagnostic disease severity demonstrated that Maori and Pacific children experienced the majority of severe “Category A” disease (56.8% vs 22.7%, p = 0.17) which was predominantly renal (73.3% vs 40%, p = 0.12) in nature. Conclusions This is the first description of the incidence and clinical manifestations of jSLE in a cohort of New Zealand children. Although limited by the small numbers involved it confirmed anecdotal suspicions that the incidence of jSLE among Maori, Pacific and Asian children is higher than European children. Lupus nephritis is also more frequent and severe in Maori and Pacific children.

Abstract
The aim of this study was to analyze the allelic and genotypic frequencies of the CCR5delta32 polymorphism in systemic lupus erythematosus (SLE) patients and to investigate a possible association of this allele with SLE susceptibility and clinical outcome. A total of 367 SLE patients and 435 healthy controls were genotyped for the CCR5delta32 polymorphism. We observed that, in European-derived individuals, the frequency of the CCR5delta32 allele was smaller in patients than in controls (2.7% vs. 7.5%, OR 0.34, 95% CI 0.17-0.65, p Bonf=0.002), suggesting that this allele could be considered a protective factor for the disease. Regarding clinical manifestations, we observed that CCR5delta32 female African-derived carrier patients presented a higher predisposition to class IV nephritis when compared with absent nephritis/other class group (13.8% vs. 3.8%, OR 37.1, 95% CI 2.8-1854.7, p Bonf=0.030). A multivariate analysis including all female patients and controlling for the presence or absence of anti-dsDNA antibodies, ethnicity and age at diagnosis showed an increased relative risk of 3.9 times for patients carrying the CCR5delta32 allele to develop class IV nephritis as compared with noncarriers. Our data suggest that the CCR5delta32 allele is a protective factor for the disease in European-derived patients and a susceptibility factor to class IV nephritis in African-derived female patients.

Abstract
Epidemiological studies with systemic lupus erythematosus (SLE) patients have been reported worldwide but, until now, a large evaluation had not been performed in Brazil. Therefore, we determined the clinical and immunological features of 888 SLE patients followed at our service from 2008 to 2012. The mean age at SLE onset and the mean disease duration were 29.9 ± 9.5 years old and 14.5 ± 8.4 years, respectively. A predominance of female gender (91.9%) and Caucasian ethnicity (69.9%) were observed. Cumulative mucocutaneous manifestations (90.7%) were most commonly identified (malar rash (83.2%), photosensitivity (76.9%)) followed by articular (87.4%), hematological (44.0%) and renal (36.9%) involvements. Antinuclear antibody was detected in all patients, followed by anti-dsDNA (35.1%), anti-Sm (21.8%) and anti-ribosomal P protein antibodies (19.8%). Additional comparison of clinical and laboratory features between genders revealed that malar rash was observed more in female SLE patients (84.5% vs. 69.4%, p = 0.001). Male lupus patients presented a higher frequency of anti-dsDNA (45.8% vs. 34.2%, p = 0.047) and a trend of more nephritis (47.2% vs. 36.0%, p = 0.059). In conclusion, we identified a high prevalence of mucocutaneous manifestations in this Brazilian SLE cohort compared to other countries, mainly malar rash that was most commonly observed in female patients. Anti-dsDNA and other specific SLE autoantibodies were also identified in a higher frequency, predominantly in the male gender.

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
BACKGROUND The clinical impression of Australian physicians is that systemic lupus erythematosus (SLE) is more prevalent and more severe in Asian patients than in their Caucasian counterparts. The presence and severity of lupus nephritis is a major determinant of prognosis in SLE, and largely determines disease impact. AIM To analyse the relationships between ethnicity and the prevalence and severity of lupus nephritis (LN) in patients attending a tertiary referral centre (The Royal Melbourne Hospital (RMH)). METHODS The ethnicity of all known patients with biopsy-proven LN was determined according to three definitions of ethnicity - ancestry, country of origin and primary language spoken. The prevalence of Asian ethnicity in the LN cohort was analysed across severity class, and was compared with the prevalences of Asian ethnicity in the general population within the hospital's geographic area, and with that in the relevant RMH cohorts of inpatients and outpatients, over the same time period. RESULTS Within this single tertiary centre, Asian patients were disproportionately represented in both the systemic lupus erythematosus (SLE) and the LN patient groups, although the distribution of histological severity of LN was not significantly different from Caucasian patients. CONCLUSION This study supports the common clinical impression that SLE is more common and more severe in the Asian-Australian population. Asian patients with SLE were more commonly diagnosed with LN. However, the spectrum of histological severity of LN was similar in Asian and Caucasian patients.

Abstract
We describe the natural history of lupus nephritis (LN) in a historical cohort of 190 white patients with the diagnosis of biopsy-proven LN followed in a single reference center.We evaluated 670 patients with systemic lupus erythematosus (SLE) consecutively followed in our department from 1970 until 2006. All patients fulfilled the 1997 revised criteria for the classification of SLE. White patients (Spanish-born) with biopsy-proven LN were selected as the study population.The cohort included 190 patients (170 female patients and 20 male) with a mean age at LN diagnosis of 31 years. Renal biopsy revealed type I LN in 8 (4%) patients, type II in 33 (17%), type III in 46 (24%), type IV in 72 (38%), type V in 28 (15%), and type VI in 3 (2%) patients. Induction remission was achieved in 85% of patients with types I and II, 78% with type III, 70% with type IV, and 32% of patients with type V. After a mean follow-up of 2391 patient-years, 62 (33%) patients developed chronic renal failure and 18 (9%) evolved to end-stage renal disease. Adjusted multivariate Cox regression analysis identified male sex (hazard ratio [HR], 4.33) and elevated creatinine at LN diagnosis (HR, 5.18) as independent variables for renal failure. Survival was 92% at 10 years of follow-up, 80% after 20 years, and 72% after 30 years.Our results suggest that biopsy-proven LN in white patients has an excellent prognosis. Ethnicity should be considered a key factor when evaluating the prognosis and therapeutic response to different agents in patients with LN.

Abstract
Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with manifold clinical manifestations and immunological abnormalities, affecting primarily women. Although accurate current data on its incidence and prevalence are largely lacking, there are numerous indications that SLE is far less common in Europeans and their descendants compared to all other ethnicities. The clinical manifestations of the disease show geographic or ethnic variation, generally being less severe in patients of European ancestry than in African, Asian, certain "Hispanic" or mestizo, and various indigenous populations. In particular, renal involvement is far more common in non-European patients. Genetic as well as environmental, sociodemographic and sociocultural factors are likely to contribute to the differences in the incidence and clinical expression of SLE.

Abstract
In a cohort of 70 systemic lupus erythematosus (SLE) patients diagnosed over 2 years period, 14 patients were found to have confirmed antecedent tuberculosis (20.0%) which was 40 times higher (p < 0.001, 95%CI 36.2-48.6) than the prevalence of tuberculosis in the local population. Demonstration of anti-histone antibodies in similar proportion of SLE patients with and without antecedent anti-TB treatment and similar proportion of renal involvement (36 vs. 40%) between anti-TB drug exposed and non-exposed patients ruled out the drugs to be causative factors in precipitating SLE in these patients with antecedent history of tuberculosis. A cohort of 30 confirmed pulmonary tuberculosis patients were also studied in parallel to demonstrate high incidence of autoantibodies in these patients but no SLE. This study suggests a role of prior tuberculosis in precipitating SLE in genetically predisposed patients.

Abstract
Asian Pacific countries include those with the highest incidence of renal failure in the world, the richest and poorest economies and unparalleled diversity of economy, culture and geography. From this come many challenges, but also a strong basis for the introduction of strategies to combat renal diseases. With a rapidly developing scientific community, Asia needs to accept the challenge of becoming a global leader in nephrology in the near future.
