Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease caused by the disorders of immune regulation but its pathogenesis is poorly understood. Progranulin (PGRN) is an immunomodulatory protein that is upregulated in SLE patients. However, the factors involved in regulating the pathogenesis of SLE by PGRN are largely unknown. We sought to investigate the role and molecular mechanisms of PGRN in SLE to develop a novel therapeutic target. We used an animal model of SLE that was induced in PGRN-deficient and normal wild type (WT) mice using pristane. PGRN concentrations were measured in SLE and the impact of PGRN deficiency was examined by measuring tissue injury and immune responses of T cells (Th1, Th2, Th17, and Treg) and B cells. SLE patients and mice showed elevated PGRN levels. Compared with WT SLE mice, inflammatory cell infiltration, tissue edema, and necrosis were alleviated in PGRN-/- SLE mice and the levels of serum chemistry markers of tissue damage and the presence of anti-double-stranded DNA and anti-ribosomal protein P0 antibodies were all significantly decreased. We further discovered that PGRN deficiency could disturb the immune responses of T cell (Th1, Th2, Th17, and Treg) and B cell responses, leading to the decrease of inflammatory cytokines including interferon-γ and interleukin-17A and increased levels of regulatory B cells. PGRN plays a proinflammatory role in the development of SLE partially through promoting the production of autoantibodies and enhancing Th1 and Th17 cell responses. This may provide new therapeutic options for patients with SLE.

Abstract
Objectives To investigate the prevalence, clinical characteristics, and prognosis of thrombocytopenia (TP) in Chinese patients with systemic lupus erythematosus (SLE). Methods The study was conducted based on the Chinese SLE Treatment and Research group (CSTAR) registry. Thrombocytopenia was defined as the platelet count<100,000/mm3 at enrollment. Severe thrombocytopenia was defined as the platelet count<50,000/mm3. The prevalence of SLE-related TP, the associations of thrombocytopenia with demographic data, organ involvements, laboratory findings, disease activity, damage, and mortality were investigated. Results Of 2104 patients with SLE, 342 patients (16.3%) were diagnosed with thrombocytopenia. The prevalence of neuropsychiatric SLE, vasculitis, myositis, nephritis, mucocutaneous lesions, pleuritis, fever, leukocytopenia and hypocomplementemia were significantly higher in patients with thrombocytopenia (p<0.05). SLE disease activity index (SLEDAI) was significantly higher in patients with thrombocytopenia (p<0.05). Multivariate analysis showed that leukocytopenia (OR = 2.644), lupus nephritis (OR = 1.539), hypocomplementemia (OR = 1.497) and elevated SLEDAI (OR = 1.318) were independently associated with thrombocytopenia (p<0.05). Long disease duration (OR = 1.006) was an independent risk factor of severe thrombocytopenia, while anti-rRNP (OR = 0.208) was an independent protective factor of severe thrombocytopenia (p<0.05). Long disease duration was an independent risk factor of mortality in patients with thrombocytopenia (RR = 1.006). The 6-year survival of patients with thrombocytopenia was significantly lower than patients without thrombocytopenia (88.2% vs. 95.5%). Conclusions Thrombocytopenia was a common manifestation of SLE and was associated with leukocytopenia, nephritis and severe disease activity. Severe thrombocytopenia tended to occur in long-term and relatively inactive SLE. Patients with SLE-related thrombocytopenia has a decreased long-term survival rate. Long disease duration was an independent risk factor of mortality in patients with thrombocytopenia.

Abstract
INTRODUCTION Accelerated atherosclerosis is a major complication of systemic lupus erythematosus (SLE), and it leads to increased cardiovascular morbidity and mortality in patients with SLE. This study aimed to investigate the natural progression of carotid intima-media thickness (CIMT), and to examine the risk factors for progression of CIMT and atherosclerotic plaques based on a Chinese SLE cohort. METHODS AND ANALYSIS Participants were continuously enrolled as outpatients of the Department of Rheumatology in Peking Union Medical College Hospital (PUMCH) from October 2013 to December 2016. Inclusion criteria were as follows: (1) age ≥18 years, (2) fulfilment of clinical classification criteria of SLE and (3) provision of signed written informed consent. Patients with clinically overt coronary artery disease, a history of cardiovascular disease (previous stroke, heart failure, myocardial infarction, angina or symptomatic peripheral artery disease) and malignancy, and pregnant/lactating women were excluded. The primary outcome is progression of CIMT from baseline. A total of 440 patients with SLE will be enrolled. Participants will receive follow-up surveys ~5 years after their baseline visit. A standard structural survey form, including demographic data, medical history, clinical and laboratory assessments and CIMT measurement, is planned for data collection at baseline and follow-up. The risk prediction model for progression of CIMT will be created by using a mixed effect model. ETHICS AND DISSEMINATION The study protocol was approved by the institutional review board of PUMCH (S-599). Informed consent was obtained from all participants according to the Declaration of Helsinki on Biomedical Research Involving Human Studies. All data will be managed confidentially according to guidelines and legislation. Dissemination will include publication of scientific papers and/or presentations of the study findings at international conferences.

Abstract
This study aimed to determine the association between different lymphocyte subsets and cytomegalovirus (CMV) infection status in patients with systemic lupus erythematosus (SLE). We performed a retrospective study among SLE patients with CMV infection and collected patient socio-demographic and clinical characteristics, as well as their recorded circulating lymphocyte subsets. Univariate and multivariable logistic regression analyses examined the relationship between CMV infection status and lymphocyte subset counts. We included 125 hospitalized patients with SLE, consisting of 88 with documented CMV infection and 37 without any evidence of CMV or other infections. Among the 88 CMV-infected patients, 65 (73.8%) patients developed CMV disease and 23 (26.2%) presented as CMV viremia. Compared to uninfected patients (1520 ± 101 cells/μL), lymphocytes remained stable among those with CMV viremia (1305 ± 272 cells/μL, P = .995). However, compared to their uninfected counterparts, there was a marked decrease in lymphocytes among patients with CMV disease (680 ± 513 cells/μL, P < .001). Analysis of lymphocyte subsets via flow cytometry showed that CD4+ T cell, CD8+ T cell, and natural killer cell counts were lower among those with CMV disease compared to those with CMV viremia and those without infection. Further, multivariable analysis showed that total lymphocyte (odds ratio [OR] 0.999, 95% confidence interval [CI] 0.998-1.000, P = .007) and CD4+ T cell counts (OR 0.99, 95% CI 0.992-0.998, P = .003) were negatively associated with CMV disease. Our findings support a potential inverse relationship between lymphopenia, specifically CD4+ T-cell lymphopenia, and CMV disease among hospitalized SLE patients.

Abstract
OBJECTIVE The objective of this paper is to assess the role of gender on survival rate and causes of death and organ damage in systemic lupus erythematosus (SLE) patients in China from 2009 to 2015. METHODS We conducted a multicenter cohort study to analyze the differences in outcome data between male and female SLE patients. A group of 1494 SLE patients who fulfilled the 1997 American College of Rheumatology SLE classification criteria were enrolled in the Chinese Systemic Lupus Erythematosus Treatment and Research Group (CSTAR) registry from April 2009 to February 2010. All enrolled patients were followed up at least once per year from 2009 to 2015. For patients who could not attend the outpatient clinic, follow-up was conducted by telephone interview. We collected demographic data, clinical manifestations and damage scores (System Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI)). Survival rates were evaluated using the Kaplan-Meier method. RESULTS This study included 1352 women and 142 men. The five-year survival rates were 92.0% for men and 97.6% for women. The survival rates of males were significant lower than for females ( p = 0.019). Male patients received methylprednisolone pulse therapy and cyclophosphamide significantly more than female patients ( p = 0.010). During follow-up, 12 male patients and 66 female patients died. The most common cause of death was infection (41.7%) for men and active SLE disease (27.3%) for women. At the end of the study, the major accumulated organ damages included renal (8.5%) and musculoskeletal (7.7%), and nervous system (5.6%) for men and renal (8.8%) and musculoskeletal (6.7%) for women. There were no significant differences in SDI scores between the two groups at baseline and at the end of the study. CONCLUSIONS Male SLE patients had lower survival rates than female patients. Male patients received more methylprednisolone pulse and cyclophosphamide therapy. The most common causes of death were infection for male patients and active SLE disease for female patients. The major accumulated organ damages were renal, musculoskeletal, and nervous system both for male and female SLE patients in China.

Improvement of Disease Management and Cost Effectiveness in Chinese Patients with Ankylosing Spondylitis Using a Smart-Phone Management System: A Prospective Cohort Study. BIOMED RESEARCH INTERNATIONAL 2019; 2019:2171475.

Abstract
Objectives Ankylosing spondylitis (AS) is a chronic disease that decreases mobility, function, and quality of life. This study introduced the "Smart-phone SpondyloArthritis Management System" (SpAMS), an interactive mobile health (mHealth) tool designed for AS/spondyloarthritis (SpA) disease management and used SpAMS data to evaluate clinical characteristics of Chinese patients with AS. Methods SpAMS integrates patient's and physician's portals in a smart phone application. The Chinese Ankylosing Spondylitis Prospective Imaging Cohort was launched using SpAMS in April 2016. Patient self-assessments were completed online at baseline and at every subsequent clinic visit. Physician-reported assessments and treatments were recorded by rheumatologists during each visit. Results In total, 1201 patients with AS [mean (SD) age, 30.6 (8.7) years; male, 82.6%] were recruited. Mean (SD) disease duration was 8.4 (6.1) years. Past or current symptoms of acute anterior uveitis (AAU), psoriasis, and inflammatory bowel disease (IBD) were observed in 21.0%, 3.7%, and 9.4% of patients, respectively. AAU and IBD occurred significantly more in patients with symptom duration > 10 years. The most commonly used medications at baseline were nonsteroidal anti-inflammatory drugs (98.2%). Patients using tumour necrosis factor inhibitors accounted for 20.8%, and 66.4% of patients used conventional synthetic disease-modifying antirheumatic drugs. At baseline, 57.2% of patients had inactive disease (ID)/low disease activity (LDA); this rate significantly improved to 79.2% after a mean follow-up of 13.3 (5.9) months. Compared with relapsed patients, new achievers of ID/LDA underwent more online patient assessments (P < .001). Problems solved in SpAMS caused 29.1% of clinic visits to a tertiary hospital unnecessary. SpAMS saved an average of 5.3 hours and 327.4 RMB per person on traffic expenses; these expenses equalled 16% of the Chinese monthly disposable personal income. Conclusions SpAMS is a time- and cost-saving disease management tool that can help patients with AS perform self-management and provide valuable data to clinicians.

Abstract
This study aimed to identify the long-term clinical outcomes and prognostic factors of patients with systemic lupus erythematosus (SLE)-associated pulmonary arterial hypertension (PAH) confirmed by right heart catheterisation.A multicentre prospective cohort of SLE-associated PAH was established. Baseline and follow-up records were collected. The primary end-point was death. The secondary exploratory end-point was treatment goal achievement (TGA), defined as an integrated outcome.In total, 310 patients were enrolled from 14 PAH centres. The 1-, 3- and 5-year survival rates were 92.1%, 84.8% and 72.9%, respectively. The 1-, 3- and 5-year TGA rates were 31.5%, 53.6% and 62.7%, respectively. Baseline serositis, 6-min walking distance >380 m and cardiac index ≥2.5 L·min−1·m−2 were identified as independent prognostic factors of TGA. Patients with baseline serositis were more likely to reach TGA after intensive immunosuppressive therapy. TGA was identified as a positive predictor of survival in patients with SLE-associated PAH.TGA was associated with long-term survival, which supports the treat-to-target strategy in SLE-associated PAH. Baseline heart function predicted both survival and treatment goal achievement in patients with SLE-associated PAH. Patients with serositis at baseline tended to benefit from intensive immunosuppressive therapy and have a better clinical outcome.

Abstract
BACKGROUND An increased prevalence of arterial stiffness in systemic lupus erythematosus (SLE) patients has been established, but the mechanisms of progression of arterial stiffness with increasing age have not been fully explored. OBJECTIVES To investigate age-related progression of arterial stiffness among SLE patients relative to healthy controls. METHODS A total of 161 female SLE patients who were enrolled in the Chinese SLE Treatment and Research group (CSTAR) registry and 135 age-matched healthy control subjects participated in this cross-sectional investigation. Traditional cardiovascular risk factors and SLE-related parameters were assessed on the day that brachial-ankle pulse wave velocity (baPWV) was examined. SAS 9.3 was used to perform all statistical analyses in this study. Linear regression and curvilinear regression models were utilized to analyze the association between age and arterial stiffness. RESULTS Arterial stiffness based on baPWV significantly differed between the SLE patients and controls in the different age groups, and within the SLE group. The baPWV increments for each age group (<25, 25-34, 35-45, and >45) were 30 cm/s, 52 cm/s, and 121 cm/s for the controls and 61 cm/s, 132 cm/s, and 155 cm/s for the SLE patients, respectively. Curvilinear regression and linear regression revealed various trends of increased arterial stiffness among the SLE patients compared with the healthy controls. The correlation coefficients between age and arterial stiffness significantly differed among the SLE patients relative to the healthy controls (correlation coefficients of 0.46478 and 0.52612, respectively; t = 2.05; P = 0.0409). Multivariate analysis revealed that age, mean blood pressure (BP) (P < 0.0001), erythrocyte sedimentation rate (ESR) (P = 0.0073), prednisone course (P = 0.0144), and SLE disease activity (P = 0.0405) were associated with arterial stiffness among the SLE patients. Further, these patients exhibited earlier exposure to and higher frequencies of several risk factors compared with the controls in each age group (<25 years: OR = 6.3253; 25-34 years: OR = 3.1043; 35-45 years: OR = 3.1316; >45 years: OR = 3.6020). CONCLUSIONS The mechanisms of the age-related progression of arterial stiffness differed among the SLE patients relative to the healthy controls. Furthermore, accelerated arterial stiffness was observed among the SLE patients relative to the healthy controls with advancing age.

Abstract
Background: Approximately 15–20% cases of systemic lupus erythematosus (SLE) are diagnosed in children. There have been a few studies reporting the epidemiological data of pediatric-onset SLE (cSLE) in China, neither comparing the differences between cSLE and adult-onset SLE (aSLE). The aim of this study was to describe the impact of age of onset on clinical features and survival in cSLE patients in China based on the Chinese SLE Treatment and Research group (CSTAR) database. Methods: We made a prospective study of 225 cSLE patients (aged < 16 years) and 1759 patients aged 16–50 years based on CSTAR registry. We analyzed initial symptoms, clinical presentations, SLE disease activity, damages, and outcomes of cSLE, as well as compared with aSLE patients. Results: The mean age of cSLE patients was 12.16 ± 2.92 years, with 187 (83.1%) females. Fever (P < 0.001) as well as mucocutaneous (P < 0.001) and renal (P = 0.006) disorders were found to be significantly more frequent in cSLE patients as initial symptoms, while muscle and joint lesions were significantly less common compared to aSLE subjects (P < 0.001). The cSLE patients were found to present more frequently with malar rash (P = 0.001; odds ratio [OR], 0.624; 95% confidence interval [CI], 0.470–0.829) but less frequently with arthritis (P < 0.001; OR, 2.013; 95% CI, 1.512–2.679) and serositis (P = 0.030; OR, 1.629; 95% CI, 1.053–2.520). There was no significant difference in SLE disease activity index scores between cSLE and aSLE groups (P = 0.478). Cox regression indicated that childhood onset was the risk factor for organ damage in lupus patients (hazard ratio 0.335 [0.170–0.658], P = 0.001). The survival curves between the cSLE and aSLE groups had no significant difference as determined by the log-rank test (0.557, P = 0.455). Conclusions: cSLE in China has different clinical features and more inflammation than aSLE patients. Damage may be less in children and there is no difference in 5- year survival between cSLE and aSLE groups.

Abstract
Objective.To determine the association between crescents and renal outcomes, and the implications on therapeutic choices.Methods.There were 231 patients with biopsy-proven proliferative lupus nephritis (PLN) who were divided into 4 groups: 59 patients were in the noncrescent group (NC); 59 patients exclusively with segmental crescents were in the segmental crescent group (SC); patients with circumferential crescents were categorized into 2 groups according to the crescentic ratio (C1 had 64 patients with ≤ 25%, and C2 had 49 patients with > 25%). Their baseline laboratory tests, histopathological manifestations, and outcomes were compared.Results.Remission rates in NC, SC, C1, and C2 groups were 92.1%, 85.4%, 95.0%, and 76.1%, respectively. Fewer patients in the C2 group achieved complete remission than the other 3 groups. For longterm outcomes evaluated by serum creatinine (SCr) doubling or endstage renal disease (ESRD), the renal survival rate was lowest in the C2 group (p = 0.003). Including clinical and pathological variables in the Cox proportional hazard regression model separately, the multivariate analysis revealed that these were independent risk factors for SCr doubling or ESRD: baseline SCr (with every 1 mg/dl increase: HR = 1.834, 95% CI 1.465–2.296; p < 0.001), hemoglobin (with every 1 g/l increase: HR = 0.970, 95% CI 0.947–0.992; p = 0.009), the proportions of cellular crescents (with every 1% increase: HR = 1.040, 95% CI 1.015–1.066; p = 0.002) and fibrocellular crescents (with every 1% increase: HR = 1.085, 95% CI 1.013–1.163; p = 0.020), and severe renal tubular atrophy (HR = 5.348, 95% CI 1.278–22.373; p = 0.022).Conclusion.PLN with crescents > 25% had worse renal outcomes both in short and long terms. Proportions of cellular and fibrocellular crescents were independent risk factors for poor renal survival.

Abstract
Background Intravenous belimumab plus standard of care (SoC) is approved in the USA and Europe for treatment of active, autoantibody-positive systemic lupus erythematosus (SLE). Methods This phase III, multicentre, randomised, double-blind, placebo-controlled study (BEL113750; NCT01345253) was conducted in 49 centres across China, Japan and South Korea (May 2011–September 2015). Patients with SLE were randomised 2:1 to intravenous belimumab 10 mg/kg or placebo, plus SoC, every 4 weeks until Week 48. The primary endpoint was the SLE Responder Index (SRI) 4 response rate at Week 52. Secondary endpoints were the percentage of patients with ≥4 point reduction in Safety of Oestrogens in Lupus Erythematosus National Assessment-SLE Disease Activity Index (SELENA-SLEDAI), SRI7, time to first severe flare and number of days prednisone (or equivalent) dose ≤7.5 mg/day and/or reduced by 50% from baseline. Safety was assessed. Results The modified intent-to-treat population included 677 patients (belimumab n=451, placebo n=226). At Week 52, the SRI4 response rate was higher with belimumab versus placebo (53.8% vs 40.1%; OR: 1.99 (95% CI: 1.40, 2.82; P=0.0001)). The percentages of patients with a ≥4 point reduction in SELENA-SLEDAI and an SRI7 response were significantly greater for belimumab versus placebo. Patients in the belimumab group had a 50% lower risk of experiencing a severe flare than those receiving placebo (P=0.0004). In patients with baseline prednisone dose >7.5 mg/day, there was a significant reduction in steroid use favouring belimumab (P=0.0228). The incidence of adverse events was similar between groups. Conclusions In patients with SLE from North East Asia, belimumab significantly improved disease activity, while reducing prednisone use, with no new safety issues.

Abstract
This study determined the flare status of SLE patients in a single-center Chinese cohort and identified the predictors of flare in this underreported Asian population. The patients were recruited from April 2009 to February 2010 at the Peking Union Medical College Hospital (PUMCH), and then followed up regularly at our clinic until December 2015. Flare was defined as an increase in SLEDAI-2K to ≥ 4 points from the previous visit, or appearing of a new SLE manifestation or worsening of a preexisting clinical or hematological manifestation (not included in SLEDAI-2K) that results in restarting or increasing corticosteroids or immunosuppressant. Baseline and follow-up data were collected, and some of them were used as variables in survival analysis for time-to-flare outcome with Kaplan-Meier survival analysis and log-rank tests. Potential predictors with significant differences were further included in a multivariate Cox regression model for confounders adjustment and hazard ratio (HR) calculation. A total of 254 patients were finally included in our analysis. Yearly flare proportion rate was 13.0-15.7%. Renal, hematologic, and neurologic were the most frequently involved organs. Multivariate analysis confirmed onset age up to 18 years (HR 2.14, 95% CI 1.09-4.19) as a flare predictor. Organ damage at entry also showed an association trend with flare (HR = 1.693, 95% CI 0.943 ~ 3.041, p = 0.078). Chinese SLE patients showed a higher prevalence for disease flare compared with other ethnics. Future studies should be designed for figuring out the prediction role of fluctuation of anti-dsDNA antibody for disease flare.

Abstract
Umbilical cord (UC)-derived mesenchymal stem cells (MSCs) show immunoregulatory properties on various immune cells and display therapeutic effects on various autoimmune diseases such as systemic lupus erythematosus (SLE). The aim of this study was to investigate the effect of the SLE environment on UC MSCs and to identify a potential serum biomarker to predict the therapeutic effect. UC MSCs were cocultured with peripheral blood mononuclear cells (PBMCs) from active lupus patients, and the proliferation, apoptosis and surface markers of UC MSCs were observed. UC MSC functional molecules were assessed by real-time polymerase chain reaction, and the signaling pathways were analyzed by Western blot. The clinical effect of MSC transplantation (MSCT) for lupus patients was followed-up, whereas baseline serum cytokines were analyzed by enzyme-linked immunosorbent assay. The coculture of PBMC from lupus patients promoted MSC proliferation. Lupus PBMCs were more potent in stimulating UC MSCs to secrete vascular endothelial growth factor (VEGF) and CXCL-12. Furthermore, lupus PBMCs activated Akt, IκB, and Stat5 signaling pathways in UC MSCs but did not affect Erk1/2 and Smad1/5/8 pathways. Moreover, our clinical study showed that higher baseline levels of IFN-γ might predict a good response to MSCT in active lupus patients. Baseline IFN-γ levels may predict clinical response to MSC therapy for active lupus patients, which will help to choose suitable patients for clinical transplantation.

Abstract
The aim of this study was to analyze the clinical characteristics of systemic lupus erythematosus (SLE) patients with joint infections. We retrospectively reviewed the medical records of 11,734 SLE patients admitted to Peking Union Medical College Hospital (PUMCH) from January 1990 to December 2016. Twenty patients who developed joint infections were identified. Subjects without joint infections (designated as control patients) were selected from the pool of SLE patients using a 1:4 systematic sampling method. The median disease duration from SLE onset to joint infection was 23 months (range 4 to 156 months). The symptoms of patients with joint infections manifested as joint pain (all cases), swelling (14 cases), and fever (15 cases). All patients had oligo-arthritis, and the knee was the joint most commonly affected joint. There were 7 patients in the Salmonella group and 5 in the Staphylococcus aureus group. One patient was infected with Streptococcus, and 7 patients were infected with Mycobacterium. SLE patients with and without joint infections demonstrated significant differences (P < 0.05) regarding the following symptoms: pre-existing arthritis (65.0 vs 33.8%), gastrointestinal involvement (5.0 vs 26.3%), cardiac damage (5.0 vs 31.3%), elevated C-reactive protein (CRP) (80.0 vs 22.5%), and elevated SLE Disease Activity Index (SLEDAI) score (≥5) (30.0 vs 77.5%). When an SLE patient presents with pre-existing arthritis and suddenly develops asymmetric oligo- or large-joint swelling and pain with elevated CRP levels and low disease activity, joint infections should be considered. Early treatment could protect the joint and improve functional outcomes.

Abstract
AIM The aim of this study was to estimate the influence of socioeconomic and geographical variables on disease phenotype and activity of systemic lupus erythematosus (SLE) in a Chinese population. METHODS Data on 904 therapy-naïve SLE patients from the Chinese SLE Treatment and Research Group (CSTAR), which is a nation-wide database of SLE patients, were used to evaluate the influence of socioeconomic status (SES) and geographical regions on disease phenotypes. The influence of regional climate and economic variables (i.e., data from the database of the Chinese Statistical Yearly Annals) on disease activity and nephropathy was further analyzed in a multivariate analysis to identify some of the environmental factors contributing to SLE. RESULTS Phenotype differences in SLE were found between patients with different SES. In the multivariate regression analysis that considered regional economic and climate factors, after adjusting for age, gender and disease duration, lower educational levels (β: -0.122, P = 0.001), lower availability of medical technical personnel (MTP) per 1000 people (β: -0.192, P < 0.001), higher annual duration of sunshine (β: 0.178, P = 0.010) and residence in southern China (β: 0.165, P = 0.001) were significantly associated with higher disease activity scores. Living in southern China (odds ratio [OR]: 1.907, P = 0.002) seemed to be a significant risk factor for nephropathy. A high number of MTP per 1000 people (OR: 0.951, P = 0.014) and relatively high temperatures were determined to be protective factors for nephropathy (OR: 0.946, P = 0.011). CONCLUSIONS The phenotype pattern and disease activity varied between SLE patients by SES and other regional variables, such as educational level, availability of medical technical personnel, annual sunshine duration and regional temperature.

Abstract
Background Systemic lupus erythematosus (SLE) leads to renal lesions, which may be clinically silent in patients with little or no proteinuria. Early detection of these lesions may improve prognosis, but early markers are controversial. This study aimed to determine renal marker proteins associated with renal lesion severity in patients with lupus nephropathy (LN) and little or no proteinuria. Material/Methods Patients with LN and little or no proteinuria (<0.5 g/24 hours) (n=187) that underwent kidney biopsy were grouped according to: low severity (Class I or II; n=116) versus high severity (Class III, IV, or V; n=71). Disease status was determined according to the SLE disease activity index (SLEDAI). Renal marker proteins (serum β2-macroglobulin, urinary β2-macroglobulin, albumin, IgG, and α1-macroglobulin) were measured using radioimmunoassay. Results Compared with the low severity group, patients in the high severity group had higher urinary albumin (11.60±8.94 versus 7.08±10.07 μg/mL, p=0.008) and urinary IgG (13.21±9.35 versus 8.74±8.90 μg/mL, p=0.007) levels. Multivariate conditional logistic regression analysis showed that urinary albumin (odds ratio (OR)=1.417, 95% confidence interval (95% CI): 1.145–1.895, p=0.001) and SLEDAI (OR=2.004, 95% CI: 1.264–3.178, p=0.003) were independently associated with severe renal lesions in these patients. Using an optimal cutoff point of urinary albumin of 7.53 μg/mL resulted in 67% sensitivity and 82% specificity for the detection of high severity renal lesions. Conclusions Urinary albumin levels and SLEDAI were independently associated with histological severity of renal lesions in patients with LN and little or no proteinuria. These parameters could be used to help select patients for renal biopsy.

Abstract
Peking Union Medical College Hospital (PUMCH) has started a single-center right heart catheterization (RHC)-based pulmonary arterial hypertension (PAH) study in systemic lupus erythematosus (SLE) since 2006. The baseline characteristics of these patients were described and the risk factor for PAH in lupus was identified.The demographic, clinical, laboratory, and treatment characteristics of SLE patients with PAH when they were registered were collected as the baseline data. A case-control study was conducted by taking the admitted SLE-non-PAH patients adjusted for age and gender in a 4:1 ratio during the same period as the controls. The associated variables were examined by binary multivariate logistic regression analysis to identify possible risk factors. A total of 111 RHC-confirmed SLE-PAH patients were enrolled, with the onset age of 34.6 ± 8.6 years old and the average SLE duration of 5 years. RHC revealed mPAP as 46.4 ± 11.4 mm Hg, CI as 2.7 ± 0.8 L/min × m, and PVR as 10.5 ± 4.8 WU. 46% of patients were WHO Fc I-II. All patients were treated with immunosuppressive agents and 65% patients had PAH-targeted therapy. The case-control study had confirmed 2 independent risk factors previously published: pericardial effusion (OR = 21.290, P < 0.001) and anti-RNP antibody (OR = 12.399, P < 0.001). Meanwhile, 6 independent variables were discovered: baseline SLE duration (OR = 1.118, P = 0.007), interstitial lung disease (OR = 17.027, P < 0.001=, without acute rash (OR = 3.258, P = 0.019), anti-SSA antibody (OR = 4.836, P = 0.004), SLEDAI≤9 (OR = 26.426, P < 0.001), ESR≤20 mm/h (OR = 12.068, P < 0.001), and uric acid > 357 μmol/L (OR = 9.666, P < 0.001) to be associated with PAH in SLE patients.The PUMCH study has shown that SLE patients complicated with PAH are usually earlier diagnosed and have less disease severity than patients without PAH. The immunosuppressive therapy rate and the PAH target therapy rate were high, which is consistent with reports from Western countries. This study has confirmed that pericardial effusion and positive anti-RNP antibody are risk factors for SLE-associated PAH. Long SLE disease duration, the presence of interstitial lung disease, without acute skin rash, positive anti-SSA antibody, low SLEDAI and ESR, and high uric acid levels are also associated with PAH in SLE patients.

Abstract
Objectives To investigate both the prevalence and clinical characteristics of serositis in Chinese patients with systemic lupus erythematosus (SLE) in a large cohort in the Chinese SLE Treatment and Research group (CSTAR) database. Methods A prospective cross-sectional study of patients with SLE was conducted based on the data from the CSTAR registry. Serositis was defined according to the 1999 revised American College of Rheumatology (ACR) criteria for SLE – that is, pleuritis/pleural effusion and/or pericarditis/pericardial effusion detected by echocardiography, chest X-ray or chest computerized tomography (CT) scan. Peritonitis/peritoneal effusion were confirmed by abdominal ultrasonography. We analysed the prevalence and clinical associations of serositis with demographic data, organ involvements, laboratory findings and SLE disease activity. Results Of 2104 patients with SLE, 345 were diagnosed with serositis. The prevalence of lupus nephritis (LN), interstitial lung disease and pulmonary arterial hypertension, as well as the presence of leukocytopenia, thrombocytopenia, hypocomplementemia and anti-dsDNA antibodies was significantly higher in patients with serositis ( P < 0.05). Significantly higher SLE disease activity scores were found in patients with serositis compared to those patients without serositis ( P < 0.05). Lupus-related peritonitis had similar clinical manifestations and laboratory profiles as serositis caused by SLE. Conclusions There is a significant association of nephropathy, interstitial lung disease, pulmonary arterial hypertension, hypocomplementemia, leukocytopenia, thrombocytopenia and elevated anti-dsDNA antibodies with serositis. The results suggest that higher SLE disease activity contributes to serositis development, and should be treated aggressively.

Abstract
Nocardiosis is an opportunistic infection that most commonly involves the lung; however, only a few case reports of autoimmune disease complicated by pulmonary nocardiosis exist in the literature. We conducted a retrospective analysis of 24 cases of both autoimmune disease and pulmonary nocardiosis at the Peking Union Medical College Hospital between 1990 and 2012. Fifty-two cases were hospitalized with nocardiosis, 24 of whom had at least 1 autoimmune disease before the diagnosis of pulmonary nocardiosis. The cohort patients consisted of 5 men and 19 women, with a mean age of 44.2 years. All were negative for human immunodeficiency virus. All but 1 patient had received immunosuppressants, including corticosteroids, cyclophosphamide, azathioprine, methotrexate, or hydroxychloroquine. Fever (87.5%), cough (83.3%), and sputum (79.2%) were the most common clinical manifestations. Ten cases were accompanied by subcutaneous nodules and/or cutaneous abscesses, and 4 had brain abscess. Half of them were lymphocytopenic. Thirteen of the 16 cases who underwent lymphocyte subtype analysis had decreased CD4+ T-cell counts. Nineteen cases had decreased serum albumin levels. Nocardia was isolated from sputum (13/24), bronchoalveolar lavage fluid (4/6), lung tissue (5/6), pleural effusions (3/5), skin or cutaneous pus (7/10), and brain tissue (1/1). The most common imaging findings were air-space opacities (83.3%), followed by nodules (62.5%), cavitations (45.8%), and masses (37.5%). Five were administered co-trimoxazole only, and the others were treated with 2 or more antibiotics. All 5 cases with skin abscesses and 2 of the 4 cases with brain abscesses were treated by surgical incision and drainage. None underwent thoracic surgery. Corticosteroid dosages were decreased in all cases, and cytotoxic agents were discontinued in some cases. Twenty-two cases recovered, and 2 died. Pulmonary nocardiosis associated with an underlying autoimmune disease showed a female predominance and presentation at younger age. Immunosuppressant therapy, lymphocytopenia, particularly low CD4+ T-lymphocyte counts, and low serum albumin levels may be disease susceptibility factors. Air-space opacities and nodules were the most common chest imaging features, and disseminated nocardiosis with lung and skin involvement was more common among them. Early diagnosis and anti-nocardial antibiotics with modulation of the basic immunosuppressive therapy were important for them.

Abstract
Background The aim of this study was to investigate the hepatitis B virus (HBV) infection rate in systemic lupus erythematosus (SLE) patients in China, and to determine the age and sex distribution. Material/Methods A total of 3981 SLE patients diagnosed in The First Affiliated Hospital of Sun Yat-sen University from January 1996 to December 2011 were retrospectively investigated for evaluation of the HBV infection rate. The HBV infection rate and the positive rate of hepatitis B surface antibody (HBsAb) and hepatitis B core antibody (HBcAb) were standardized to national census data in 2000 and compared with the prevalence found in the 2006 national survey. Results The age and sex standardized HBV infection rate in Chinese SLE patients was 3.3%. The age and sex standardized positive rate of HBsAb and HBcAb were 58.1% and 26.1%, respectively. As compared with the prevalence from the 2006 national survey, the HBV infection rate and the positive rate of HBcAb were lower and the positive rate of HBsAb was higher in SLE patients aged 15–49 years old compared to peers in the general population. There was no difference in HBV infection rate between males and females (4.2% vs. 2.8%, p=0.088) in SLE patients. Conclusions The HBV infection rate was relatively lower in SLE patients compared with the general population, but there was no difference in pediatric patients or patients aged above 50 years old. Unlike in the general population, the HBV infection rate had no statistical differences between males and females in SLE patients.

Abstract
Introduction Many studies have shown that differences were observed between male and female lupus patients. Although systemic lupus erythematosus (SLE) affects mostly females (female:male ratio 9:1), male SLE patients show higher mortality due to kidney and neurological disease. Currently there are limited epidemiological data concerning lupus in the Chinese population. As such, the Chinese SLE Treatment and Research group (CSTAR) developed the first online registry of Chinese lupus patients in 2009, and represents a multicenter observational study that attempts to describe and compile the major clinical characteristics of lupus in Chinese patients. Objective To investigate the effect of gender on the phenotypes of Chinese SLE patients. Patients and methods Data for 2104 SLE patients were prospectively collected and included in the CSTAR registry. Patients fulfilled the 1997 American College of Rheumatology (ACR) SLE classification criteria. We conducted a cross-sectional case-control study to analyze patient clinical and laboratory data at onset and at enrollment. SLE disease activity scores (SLEDAI) were also measured at enrollment. Results This study included 1914 women and 190 men. Males and females showed no differences in mean ages at onset, delay of diagnosis and disease duration. Males presented more frequently with fever ( p = 0.003), while musculoskeletal involvement ( p = 0.001) and cytopenia ( p = 0.017) was more common in females as the initial manifestation at onset of SLE. For manifestations at enrollment, males presented more frequently with fever ( p = 0.005), renal disease ( p = 0.019), vasculitis ( p = 0.032) and neuropsychiatric lupus ( p = 0.007). For cumulative manifestations at enrollment, males presented more frequently with discoid rash ( p < 0.001) and neuropsychiatric lupus ( p = 0.036), while less frequently with arthritis ( p = 0.011). However, the laboratory data showed no significant differences between the two groups at enrollment. Males also had higher SLEDAI scores at enrollment ( p = 0.002). Conclusions Renal disease, vasculitis and neuropsychiatric lupus are more common in male SLE patients with higher SLEDAI scores compared to female SLE patients in China.

Long-term survival and death causes of systemic lupus erythematosus in China: a systemic review of observational studies. Medicine (Baltimore) 2015; 94:e794. [PMID: 25929930 PMCID: PMC4603034 DOI: 10.1097/md.0000000000000794] [Citation(s) in RCA: 70] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2015] [Revised: 03/21/2015] [Accepted: 03/29/2015] [Indexed: 02/07/2023] Open
Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with an increased risk of death compared to general population. Although previous studies showed improvement in survival of SLE, the long-term prognosis has not been elaborated in China.This study aims to integrate the observational studies estimating current long-term survival of Chinese SLE patients and analyze the death-cause situation of SLE in China.The study is a systemic review of English and non-English articles using MEDLINE, EMBASE, CNKI, WANFANG, and SINOMED databases. Additional studies were found by consultation with clinical experts, browse of references in selected papers, and search of related textbooks. Our major search terms were SLE, follow-up, prognosis, survival, mortality, and China.We included cohort studies for survival analysis, and both cohort studies and case series for death-cause analysis in China.The extraction of the articles were done by 2 authors independently using predesigned charts, including characteristics of study, clinical data, analyzing data, and study quality indicators.All pooled analyses were conducted both for random-effects model and fixed-effects model. Funnel plots and Egger regression tests were applied to check potential publication bias. Heterogeneity was tested by sensitivity analysis. We identified 5 studies for survival analysis comprising 4469 Chinese patients with SLE (380 observed deaths). Thirty-six studies were suitable for death-cause analysis with 2179 observed deaths (derived from more than 20,000 Chinese patients with SLE). The overall pooled survival rates for SLE in China were 94% for 5-year survival rate and 89% for 10-year survival rate after disease onset from the year 1995 to 2013, which were similar with previous publications in Asia-Pacific area. The proportions of different causes of death showed infection (33.2%), renal involvement (18.7%), lupus encephalopathy (13.8%), and cardiovascular disease (11.5%) as the top 4 causes.The overall survival rates for Chinese patients with SLE resembled previous publications in Asia-Pacific area. But the death causes of SLE in China were of some differences indicating relatively higher proportion of infection and lupus encephalopathy and lower cardiovascular disease. Ethnicity and more aggressive treatment might have contributed to the difference in death composition.

Abstract
Pulmonary arterial hypertension (PAH) is characterized by vascular remodeling of pulmonary arterioles that leads to increased pulmonary vascular resistance, right heart failure, and death. It is associated with connective tissue diseases, including systemic sclerosis, systemic lupus erythematosus, and mixed connective tissue disease. PAH is characterized by dyspnea on exertion and fatigue. Syncopal events suggest severe disease. Patients may present with signs of right heart failure. One- and 3-year survival rates are approximately 81% and 52%, respectively. Given the high prevalence and mortality, algorithms for screening are currently under investigation and will hopefully lead to earlier diagnosis and improved survival.

Abstract
With this study, we provide insight into the clinical characteristics, laboratory characteristics, and organ damage associated with incomplete lupus syndromes (ILE) and search for predictors of organ damage in ILE. A retrospective chart review was performed on 77 hospitalized patients with ILE. The control patient group comprised 2104 systemic lupus erythematosus (SLE) patients who were entered into the Chinese SLE Treatment and Research group (CSTAR). The Systemic Lupus International Collaborating Clinics (SLICC)/ACR Damage Index (SDI) was used to classify damage features. Based on their SDI score, ILE patients were divided into SDI > 0 and SDI = 0 groups. The percentages of anti-SSA-seropositive (54.5 %) and anti-RNP-seropositive (24.7 %) patients with ILE were higher than those found among the SLE patients from CSTAR (p < 0.001). The mean SDI score was 0.66 (range 0-2), and a damage score greater than 0 was present in 41 (53.3 %) patients. The most prevalent damage category was pulmonary damage, present in 17 (22.1 %) patients. Peripheral vascular damage occurred in individuals who were significantly older than those who had musculoskeletal damage (p = 0.031). The subgroup with SDI > 0 had a higher mean age (36.8 ± 2.04 years) than those with SDI = 0 (30.8 ± 2.08 years; p = 0.044). The mean SLEDAI score in the SDI > 0 patient group (8.2 ± 0.74) was higher than that of the SDI = 0 group (4.8 ± 0.54; p = 0.001). ILE patients may include a subset that is likely to experience progressive organ damage. Organ damage was more common in patients of older age and with high SLEDAI scores.

Abstract
In the past two decades, Chinese rheumatology has developed rapidly in terms of both clinical practice and basic research. Many rheumatology departments and divisions have been established, creating positions for more residents to join rheumatology practices. Numerous studies of rheumatic diseases have been published in recent years by Chinese rheumatologists and immunologists, supported by government funding that has dramatically increased over the past few years. These studies are focused mainly on epidemiology, mechanisms, early diagnosis and interventions of rheumatic diseases. Increasing numbers of national and international scientific activities in China, including research collaborations, education programmes and conferences have greatly helped the development of rheumatology. In this APLAR series article, the major, high-impact studies and latest developments in Chinese rheumatology are reviewed.

Abstract
OBJECTIVES Our study aimed to investigate the effect of cigarette smoking on the clinical phenotype of patients registered in the Chinese Systemic Lupus Erythematosus (SLE) Treatment and Research (CSTAR) group registry database, the first online registry of Chinese patients with SLE. METHODS A prospective cross-sectional study of Chinese SLE patients was conducted using the CSTAR. Our case-control analysis was performed on age- and gender-matched subjects to explore the potential effect of cigarette smoking on the clinical manifestation of SLE. RESULTS Smokers comprised 8.9% (65/730) of patients, and the ratio of females/males was 19/46. Thirty-nine patients were current smokers, and 26 were ex-smokers. Data showed significant differences between smokers and nonsmokers in the following areas: nephropathy (58.5% vs. 39.2%; p = 0.003), microscopic hematuria (30.8% vs. 19.1%; p = 0.025), proteinuria (53.8% vs. 34.4%; p = 0.002), and SLE Disease Activity Index(DAI) scores (12.38±8.95 vs. 9.83±6.81; p = 0.028). After adjusting for age and gender, significant differences between smokers and nonsmokers were found with photosensitivity (35.9% vs. 18%; p = 0.006), nephropathy (59.4% vs. 39.8%; p = 0.011), and proteinuria (54.7% vs. 35.2%). Although smokers tended to have greater disease severity compared with nonsmokers (SLEDAI scores: 12.58±8.89 vs.10.5±7.09), the difference was not significant (p = 0.081). CONCLUSIONS Cigarette smoking triggers the development and exacerbation of SLE, especially with respect to renal involvement. Chinese smokers with SLE should be advised to discontinue cigarette use.

Abstract
OBJECTIVE To study the factors associated with fetal loss in Chinese women with systemic lupus erythematosus (SLE) in a large cohort of SLE patients in the CSTAR (Chinese SLE Treatment and Research Group) registry. METHODS We compared the clinical characteristics and auto-antibody profiles between SLE patients with fetal loss and SLE patients with normal pregnancies. The relationship between selected variables and fetal loss was examined by univariate analysis and binary logistic regression analysis. RESULTS A total of 992 patients with 2026 pregnancies were recruited. Fifty women experienced fetal loss, including 49 spontaneous abortion, eight stillbirths and three neonatal deaths. The overall fetal loss rate was 3.0% (60/2026). Arthritis and serositis were observed significantly more frequently (P < 0.05) in normal pregnancy women. The rate of thrombocytopenia was significantly increased in patients with fetal loss (30.0% vs. 16.1%, P = 0.010), while there was no statistically significant difference in the frequency of nephropathy, central nervous system involvement between the normal pregnancy group and fetal loss group. Factors that associated with fetal loss included anti-phospholipid antibodies (aPL) (OR 2.299; 95% CI 1.058-4.993; P = 0.035) and anti-Sjögren syndrome antigen A (SSA) antibody (OR 2.283; 95% CI 1.275-4.088; P = 0.005), and thrombocytopenia (OR 2.241; 95% CI 1.192-4.213; P = 0.012). However, arthritis (OR 0.544, 95% CI 0.307-0.965, P = 0.037) was associated with favorable fetal outcome. CONCLUSIONS Both univariate analysis and binary logistic regression analysis suggest that thrombocytopenia, aPL antibodies and anti-SSA antibody are associated with fetal loss in Chinese SLE women, while arthritis may be a possible factor related to favorable pregnancy outcome.

Abstract
Intestinal pseudo-obstruction (IPO) is a rare but dangerous complication of systemic lupus erythematosus (SLE) when the patient has no other manifestations except gastrointestinal symptoms. We performed 1 patient with a 2-month history of recurrent vomiting and abdominal distension. She admitted past surgical histories of cesarean section and appendectomy. A physical examination revealed tenderness in the right lower abdominal on palpation and bowel sounds were weak, 2 to 3 bpm. An x-ray and CT of her abdomen showed intestinal obstruction. The initial diagnosis was adhesive intestinal obstruction. She received surgical treatment because her symptoms had gradually become more frequent and persistent. But she vomited again 2 weeks later after the surgery. Further immunology tests indicated that she had an IPO secondary to SLE. We treated the patient with methylprednisolone pulse for 3 days and followed by prednisone orally. The patient had a good response. Complete remission was achieved on 8 years follow-up. The importance of IPO secondary to SLE lies in an early diagnosis. After the diagnosis is established, immunosuppressive therapy should be the initial and first-line treatment, and surgical intervention is often disappointing and should be carefully avoided. It is necessary to enhance awareness of doctors to IPO secondary to SLE.

Abstract
PURPOSE To investigate clinical characteristics of Purtscher-like retinopathy and its clinical implications among patients with systemic lupus erythematosus (SLE). DESIGN Observational case series. METHODS setting: Tertiary medical center. patient population: Patients with SLE who were diagnosed with Purtscher-like retinopathy between 2002 and 2013. observation procedures: Assessment and follow-up in the ophthalmology department. main outcome measure: Visual acuity and funduscopic examination at presentation and at 6 month follow-up, with analysis of the association between Purtscher-like retinopathy and other systemic involvement of SLE and overall disease activity. RESULTS Among 5688 patients with SLE evaluated, 8 cases of Purtscher-like retinopathy were diagnosed. Typical fundus abnormalities included Purtscher flecken, cotton-wool spots, retinal hemorrhages, macular edema, optic disk swelling, and a pseudo-cherry red spot. Fluorescein angiography abnormalities included areas of capillary nonperfusion corresponding to the retinal whitening, late leakage, peripapillary staining, precapillary occlusion, and slower filling of vessels. The prevalence of central nervous system lupus was significantly higher among those with Purtscher-like retinopathy (6/8) than among 240 patients randomly sampled from those without Purtscher-like retinopathy. A very high SLE Disease Activity Index (≥20) was present in all 8 patients with Purtscher-like retinopathy. All patients received corticosteroids combined with immunosuppressants. For the majority of patients, optic atrophy developed during follow-up with persistent low visual acuity. CONCLUSION As a rare and severe ophthalmic complication of SLE, Purtscher-like retinopathy was associated with central nervous system lupus and highly active disease. Visual acuity recovery was usually poor despite prompt treatment.

Abstract
A 35-year-old female patient was diagnosed with pulmonary arterial hypertension (PAH) by right heart catheterization (RHC) in the 3rd month of systemic lupus erythematosus (SLE) duration with high disease activity. Through methylprednisolone pulse therapy, she got total recovery from PAH proven by repeat catheterization and follow-ups. This is the first simultaneously diagnosed, totally recovered, gold standard-proved SLE-PAH case ever reported in the literature. We would like to share this successful case, and at the same time, we want to highlight the relationship between presentation of PAH and active disease manifestations of SLE patients, and to discuss how immune suppressive treatment could benefit this subset of patients.

Abstract
In emerging countries, systemic lupus erythematosus (SLE) has been associated with several unfavorable outcomes including disease activity, damage accrual, work disability and mortality. Poor socioeconomic status (SES) and lack of access to healthcare, especially in medically underserved communities, may be responsible for many of the observed disparities. Diagnostic delay of SLE or for severe organ damages (renal involvement) have a negative impact on those adverse outcomes in lupus patients who either belong to minority groups or live in emerging countries. Longitudinal and observational prospective studies and registries may help to identify the factors that influence poor SLE outcomes in emerging countries. Infection is an important cause of mortality and morbidity in SLE, particularly in low SES patients and tuberculosis appears to be frequent in SLE patients living in endemic areas (mainly emerging countries). Thus, tuberculosis screening should be systematically performed and prophylaxis discussed for patients from these areas. SLE treatment in the developing world is restricted by the availability and cost of some immunosuppressive drugs. Moreover, poor adherence has been associated to bad outcomes in lupus patients with a higher risk of flares, morbidity, hospitalization, and poor renal prognosis. Low education and the lack of money are identified as the main barrier to improve lupus prognosis. Newer therapeutic agents and new protocols had contributed to improve survival in SLE. The use of corticoid-sparing agents (hydroxychloroquine, methotrexate, azathioprine and mycophenolate mofetif) is one of the most useful strategy; availability of inexpensive generics may help to optimize access to these medications.

Chinese SLE treatment and research group registry: III. association of autoantibodies with clinical manifestations in Chinese patients with systemic lupus erythematosus. J Immunol Res 2014; 2014:809389.

Abstract
We investigated the characteristics of Chinese SLE patients by analyzing the association between specific autoantibodies and clinical manifestations of 2104 SLE patients from registry data of CSTAR cohort. Significant (P < 0.05) associations were found between anti-Sm antibody, anti-rRNP antibody, and malar rash; between anti-RNP antibody, anti-SSA antibody, and pulmonary arterial hypertension (PAH); between anti-SSB antibody and hematologic involvement; and between anti-dsDNA antibody and nephropathy. APL antibody was associated with hematologic involvement, interstitial lung disease, and a lower prevalence of oral ulcerations (P < 0.05). Associations were also found between anti-dsDNA antibody and a lower prevalence of photosensitivity, and between anti-SSA antibody and a lower prevalence of nephropathy (P < 0.05). Most of these findings were consistent with other studies in the literature but this study is the first report on the association between anti-SSA and a lower prevalence of nephropathy. The correlations of specific autoantibodies and clinical manifestations could provide clues for physicians to predict organ damages in SLE patients. We suggest that a thorough screening of autoantibodies should be carried out when the diagnosis of SLE is established, and repeated echocardiography annually in SLE patients with anti-RNP or anti-SSA antibody should be performed.

Abstract
Objectives To estimate the prevalence of pulmonary arterial hypertension (PAH) and risk factors for PAH in patients registered in the Chinese SLE Treatment and Research group (CSTAR) database, the first online registry of Chinese patients with systemic lupus erythematosus (SLE). Methods A prospective cross-sectional study of patients with SLE was conducted using the CSTAR registry. Resting transthoracic echocardiography was used to estimate pulmonary artery pressure (PAP); PAH was defined as systolic PAP (PASP) ≥40 mmHg. Patients with interstitial lung disease, valvular disease or cardiomyopathy were excluded because of disease influence on PAP. We explored potential risk factors for PAH including patient characteristics, organ involvement, laboratory findings and SLE disease activity. Results Of 1934 patients with SLE, 74 had PASP with 54.2 ± 17.1 (40,106) mmHg and were diagnosed with probable PAH. The incidences of lupus nephritis, pleuritis, pericarditis, hypocomplementemia, anti-SSA, and anti-ribonucleoprotein (RNP) were significantly higher in patients with PAH than in those without ( p<0.05). SLE disease activity was significantly higher in patients with PAH than in unaffected patients ( p<0.05). Multivariate analysis indicated that pericarditis (odds ratio (OR) = 4.248), pleuritis (OR = 3.061) and anti-RNP (OR = 2.559) were independent risk factors for PAH in patients with SLE ( p<0.05). Conclusions The possible prevalence of PAH was 3.8% in Chinese patients with SLE in the CSTAR registry. The significant association of pericarditis, pleuritis and anti-RNP positivity with PAH suggests that higher disease activity and vasculopathy may both contribute to the development of PAH in SLE, which need be treated aggressively to improve prognosis.
