RESUMO
OBJECTIVES: This study explores the clinical characteristics associated with the occurrence of acute anterior uveitis (AAU) in patients with axial spondyloarthritis (axSpA) within a large, multicentre database. METHODS: This observational, cross-sectional study of patients with axSpA used data from the Chinese Spondyloarthritis Registry between August 1, 2018, and March 31, 2020. The demographic and clinical features of patients with and without AAU were compared. Univariate and multivariate analyses were performed to determine the association between variables and uveitis. RESULTS: A total of 4304 patients were included in this study. The prevalence of AAU in patients with axSpA was 10.59%. Multivariate logistic regression analysis revealed a positive correlation between AAU and age at diagnosis (odds ratio [OR], 1.026; p<0.001), disease duration (OR, 2.117; p<0.001), current or past Achilles tendinitis (OR, 1.692; p<0.001), current or past dactylitis (OR, 1.687; p=0.002), current or past psoriasis (OR, 3.932; p<0.001), presence of human leukocyte antigen-B27 (HLA-B27) (OR, 2.787; p<0.001), and a good response to non-steroidal anti-inflammatory drugs (NSAIDs) (OR, 1.343; p=0.027). CONCLUSIONS: AAU was the most common extra-articular manifestation in the Chinese Spondyloarthritis Registry. In Chinese patients with axSpA, older age at diagnosis, longer disease duration, presence of HLA-B27, current or past Achilles tendinitis, current or past dactylitis, current or past psoriasis, and a good response to NSAIDs were positively associated with AAU.

INTRODUCTION: Anemia and malnutrition are recognized indicators of suboptimal physical condition in chronic inflammatory diseases. This study aimed to examine the association between anemia, low body mass index (BMI), and clinical outcomes in axial spondyloarthritis (axSpA). METHOD: This cross-sectional analysis utilized data from the multicenter ChinaSpA cohort. A total of 4146 participants with axSpA were categorized into four groups based on BMI and hemoglobin levels: those with both anemia and low BMI, those with anemia only, those with low BMI only, and those with neither condition. Logistic regression analyses were performed to analyze the association between anemia, low BMI, inflammation status, functional impairment, and disease activity. RESULTS: Anemia was present in 13.94%, low BMI in 11.99%, and both conditions in 2.15% of axSpA participants. Those with both anemia and low BMI showed significantly higher levels of inflammation (hypersensitive C-reactive protein [hsCRP] 30.60 mg/L vs. 8.44 mg/L), functional impairment (Bath Ankylosing Spondylitis Functional Index [BASFI] 3.80 vs. 2.10), and disease activity (Bath Ankylosing Spondylitis Disease Activity Index [BASDAI] 4.52 ± 2.04 vs. 3.67 ± 2.21; Ankylosing Spondylitis Disease Activity Score calculated with C-reactive protein [ASDAS_CRP] 3.51 ± 1.10 vs. 2.62 ± 1.21) compared to those without these conditions. After adjusting for sex and age, significant associations were observed between elevated hsCRP levels and the presence of low BMI (odds ratio [OR] 1.44, 95% CI 1.17-1.78), anemia (OR 1.91, 95% CI 1.56-2.32), and their concurrent presence (OR 3.59, 95% CI 2.22-5.80). Similarly, increased BASFI was significantly associated with low BMI (OR 1.57, 95% CI 1.25-1.97), anemia (OR 1.47, 95% CI 1.19-1.80), and their combination (OR 3.11, 95% CI 2.02-4.78). CONCLUSION: All-cause anemia and low BMI are prevalent complications in patients with axSpA, exhibiting a significant correlation with elevated inflammation status and functional impairment. The simultaneous occurrence of anemia and low BMI particularly exacerbates clinical outcomes, emphasizing the critical role of comprehensive nutritional assessment and management in the therapeutic strategy for axSpA.
RESUMO
OBJECTIVE: Patients with systemic lupus erythematosus (SLE) have an increased risk of venous thromboembolism (VTE). We conducted this study to develop a risk score algorithm for VTE in patients with SLE that provides individualised risk estimates. METHODS: We developed a clinical prediction model of VTE in 4502 patients with SLE based on the Chinese SLE Treatment and Research group cohort (CSTAR) from January 2009 to January 2020 and externally validated in 3780 patients with SLE in CSTAR from January 2020 to January 2022. Baseline data were obtained and VTE events were recorded during the follow-up. The prediction model was developed to predict VTE risk within 6 months in patients with SLE, using multivariate logistic regression and least absolute shrinkage and selection operator. SLE-VTE score and nomogram were established according to the model. RESULTS: A total of 4502 patients included in the development cohort, 135 had VTE events. The final prediction model (SLE-VTE score) included 11 variables: gender, age, body mass index, hyperlipidaemia, hypoalbuminaemia, C reactive protein, anti-ß2GPI antibodies, lupus anticoagulant, renal involvement, nervous system involvement and hydroxychloroquine, with area under the curve of 0.947 and 0.808 in the development (n=4502) and external validation cohort (n=3780), respectively. According to the net benefit and predicted probability thresholds, we recommend annual screening of VTE in high risk (≥1.03%) patients with SLE. CONCLUSION: Various factors are related to the occurrence of VTE in patients with SLE. The proposed SLE-VTE risk score can accurately predict the risk of VTE and help identify patients with SLE with a high risk of VTE who may benefit from thromboprophylaxis.

BACKGROUND: Avascular necrosis is a common organ damage in SLE patients, which can influence patients' life quality. Conflicting results exist in risk factors of AVN in SLE patients. The aim of this study was to illustrate risk factors predicting the occurrence of avascular necrosis (AVN), also known as osteonecrosis, in systemic lupus erythematosus (SLE) patients in Chinese SLE Treatment and Research Group (CSTAR), a multi-center cohort of Chinese SLE patients. METHODS: SLE patients in CSTAR without existing AVN at registration were included. At least two follow-ups and an observation period of no less than 2 years for AVN event were required. Univariate and multivariate Cox regression analyses were used to evaluate risk factors for AVN in SLE patients. Coefficient B was transformed to risk score for the development of a risk stratification model. RESULTS: One hundred six (2.59%) of 4091 SLE patients were diagnosed AVN during follow-ups of no less than 2 years. Multi-variate Cox regression analysis suggested that SLE onset age ≤ 30 (HR 1.616, p 0.023), arthritis (HR 1.642, p 0.018), existing organ damage (SDI ≥ 1) at registration (HR 2.610, p < 0.001), positive anti-RNP (HR 1.709, p 0.006), and high glucocorticoid maximum daily dose at registration (HR 1.747, p 0.02) were independent risk factors. A risk stratification system was developed according to the risk factors, and patients were divided into high risk (3-6) and low risk (0-2). The AUC of 0.692 indicated moderate discrimination. The calibration curve in internal validation was drawn. CONCLUSION: Patients with SLE onset age ≤ 30, arthritis, existing organ damage (SDI ≥ 1) at registration, positive anti-RNP, and high glucocorticoid maximum daily dose at registration are at high risk for AVN and require attention.

IMPORTANCE: Digital health applications have been shown to be effective in the management of chronic diseases with simple treatment targets. The potential clinical value of digital health applications in rheumatoid arthritis (RA) has not been well studied. OBJECTIVE: To investigate whether assessing patient-reported outcomes using digital health applications could result in disease control for patients with RA. DESIGN, SETTING, AND PARTICIPANTS: This is a multicenter, open-label randomized clinical trial in 22 tertiary hospitals across China. Eligible participants were adult patients with RA. Participants were enrolled from November 1, 2018, to May 28, 2019, with a 12-month follow-up. The statisticians and rheumatologists who assessed disease activity were blinded. Investigators and participants were not blind to group assignment. Analysis was conducted from October 2020 to May 2022. INTERVENTIONS: Participants were randomly assigned at a 1:1 ratio (block size of 4) to a smart system of disease management group (SSDM) or a conventional care control group. Upon the completion of the 6-month parallel comparison, patients in the conventional care control group were instructed to use the SSDM application for an extension of 6 months. MAIN OUTCOMES AND MEASURES: The primary outcome was the rate of patients with disease activity score in 28 joints using the C-reactive protein (DAS28-CRP) of 3.2 or less at month 6. RESULTS: Of 3374 participants screened, 2204 were randomized, and 2197 patients with RA (mean [SD] age, 50.5 [12.4] years; 1812 [82.5%] female) were enrolled. The study included 1099 participants in the SSDM group and 1098 participants in the control group. At month 6, the rate of patients with DAS28-CRP of 3.2 or less was 71.0% (780 of 1099 patients) in the SSDM group vs 64.5% (708 of 1098 patients) in the control group (difference between groups, 6.6%; 95% CI, 2.7% to 10.4%; P = .001). At month 12, the rate of patients with DAS28-CRP of 3.2 or less in the control group increased to a level (77.7%) that was comparable with that (78,2%) in the SSDM group (difference between groups, -0.2%; 95% CI, -3.9% to 3.4%; P = .90). CONCLUSIONS AND RELEVANCE: In this randomized clinical trial of RA, the use of a digital health application with patient-reported outcomes was associated with an increase in disease control rate. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03715595.

BACKGROUND: Takayasu arteritis (TAK) is a large-vessel vasculitis with high relapse rate. Longitudinal studies identifying risk factors of relapse are limited. We aimed to analyze the associated factors and develop a risk prediction model for relapse. METHODS: We analyzed the associated factors for relapse in a prospective cohort of 549 TAK patients from the Chinese Registry of Systemic Vasculitis cohort between June 2014 and December 2021 using univariate and multivariate Cox regression analyses. We also developed a prediction model for relapse, and stratified patients into low-, medium-, and high-risk groups. Discrimination and calibration were measured using C-index and calibration plots. RESULTS: At a median follow-up of 44 (IQR 26-62) months, 276 (50.3%) patients experienced relapses. History of relapse (HR 2.78 [2.14-3.60]), disease duration <24 months (HR 1.78 [1.37-2.32]), history of cerebrovascular events (HR 1.55 [1.12-2.16]), aneurysm (HR 1.49 [1.10-2.04], ascending aorta or aortic arch involvement (HR 1.37 [1.05-1.79]), elevated high-sensitivity C-reactive protein level (HR 1.34 [1.03-1.73]), elevated white blood cell count (HR 1.32 [1.03-1.69]), and the number of involved arteries ≥6 (HR 1.31 [1.00-1.72]) at baseline independently increased the risk of relapse and were included in the prediction model. The C-index of the prediction model was 0.70 (95% CI 0.67-0.74). Predictions correlated with observed outcomes on the calibration plots. Compared to the low-risk group, both medium and high-risk groups had a significantly higher relapse risk. CONCLUSIONS: Disease relapse is common in TAK patients. This prediction model may help to identify high-risk patients for relapse and assist clinical decision-making.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease involving multiple tissues and organs. Frequent flare has been regarded as one of the main problems in the diagnosis and treatment of SLE, while the causes for frequent flare has remained to be unclear. We summarized the survival status and the situation of recurrence of SLE patients. The research progress regarding the recurrence and its mechanism will be reviewed from the aspects of genetic factors, environmental factors (i.e. infection, ultraviolet, vitamin D, chemical pollutants), drug and patient compliance, systemic damage and disease status, sex hormones and pregnancy, and social psychology. The implication is to explore effective clinical intervention to alleviate the SLE disease and improve the living quality of the patients.

OBJECTIVE: To identify the alterations of CD8+ T cells in blood and labial salivary glands (LSGs) of patients with Primary Sjögren's syndrome (pSS). METHODS: Blood samples from 24 pSS patients were assayed for CD38+ HLA-DR+ CD8+ (activated CD8+, aCD8+) T cells and serum IFN-γ and TNF-α, using flow cytometry and ELISA respectively, and compared with samples from 27 healthy controls. Immunohistochemistry was used to count CD8+ T cells in LSG tissues of 24 pSS patients and of 6 control patients with normal pathology. RESULTS: pSS patients had more aCD8+ T cells than aCD4+ T cells (medians 33.13% vs. 9.43%, p < 0.0001), and had an increased level of aCD8+ T cells (medians 33.13% vs. 16.48%, p < 0.0001) and serum IFN-γ (medians 1026 pg/mL vs. 0.00 pg/mL, p < 0.0001) compared to the healthy controls. The levels of aCD8+ T cells and IFN-γ were both significant positively correlated with European League Against Rheumatism Sjögren's Syndrome Disease Activity Index, IgG, anti-nuclear antibodies, rheumatoid factor. The LSGs focus score (FS) ≥1 group had more CD8+ T cell counts than 0≤ FS <1 group and control group (medians 256/mm2 vs. 126/mm2 and 256/mm2 vs. 64/mm2 respectively, both p < 0.05). CONCLUSION: The aCD8+ T cells and IFN-γ are positively correlated with each other, and predominantly elevated in the blood of pSS patients. In the LSG tissues of pSS, CD8+ T cell counts increase with severity of the lesions. CD8+ T cells may play crucial role in the pathogenesis of pSS. Key Points ⢠Primary Sjögren's syndrome (pSS) is a chronic and systemic autoimmune disease. pSS patients had elevated blood levels of CD38 + HLA-DR+ CD8+ T cells and IFN-γ. ⢠The CD38 + HLA-DR+ CD8+ T cells positively correlated with disease parameters and serum IFN-γ. ⢠The salivary glands of pSS patients had appreciable CD8 + lymphocyte infiltration. CD8+ T cells may play crucial role in the pathogenesis of pSS.

The coronavirus disease 2019 (COVID-19) pandemic has imposed enormous morbidity and mortality burdens. Patients with rheumatic diseases (RDs) are vulnerable to the COVID-19 infection, given their immunocompromised status. Ensuring acceptance of the COVID-19 vaccine is important and has attracted attention by health professionals. In this study, we designed an online cross-sectional survey that used an online questionnaire from 8 May 2021 to 4 October 2021. Attitudes toward the COVID-19 vaccination, personal information, current disease activity status, adverse events (AEs), and knowledge sources of vaccines were collected. Descriptive statistics, nonparametric tests, and ordinal logistic regression were used to analyze the data. A total of 1022 questionnaires were received, among which 70.2% (720/1022) of patients with RDs agreed to vaccination, while only 31.6% of patients were actually vaccinated. Male, employed, high-income patients and those with inactive disease showed a more positive attitude. Concerns of AEs and disease flare were the main factors affecting vaccination willingness. Only 29.6% (304/1022) of patients thought they had received enough information about the COVID-19 vaccine from their doctors. In conclusion, most patients with RDs in China intended to get vaccinated, although the vaccination rate in this particular population was low. Rheumatologists should take more responsibility in COVID-19 vaccination education of patients with RDs.
RESUMO
Background: Systemic lupus erythematosus (SLE) can significantly influence patients' quality of life and subjective well-being (SWB), but the relationships between clinical characteristics, SWB, and related psychological factors have been little studied. Objective: To measure SWB in patients with SLE and examine how major clinical determinants, emotional variables, and related positive factors affect SWB. Methods: Overall, 1,110 patients with SLE from the Chinese SLE Treatment and Research Group (CSTAR) and 198 age and gender-matched individuals from the general population without self-reported SLE were invited to complete questionnaires of SWB evaluated by the satisfaction with life scale (SWLS), emotional variables assessed by the patient health questionnaire-9 (PHQ-9), and general anxiety disorder-7 (GAD-7) and related positive factors assessed by the self-esteem scale (SES), general self-efficacy scale (GESE), and Connor-Davidson resilience scale (CD-RISC). The multivariate linear regression was used to examine the relationship between clinical manifestations and SWB. Results: Life satisfaction was significantly lower (p < 0.001) in patients with SLE than in the general population. Active skin involvement (OR = 0.923, 95% CI = 0.868-0.981, p < 0.05) was negatively associated with life satisfaction scores, and age at enrollment (OR = 1.160, 95% CI = 1.092-1.230, p < 0.001) were positively associated with life satisfaction scores in the multivariate regression model. The cumulative organ damage was significantly associated with depression (OR = 1.085, 95% CI = 1.022-1.153, p < 0.01) and the loss of self-esteem (OR = 1.067, 95% CI = 1.004-1.133, p < 0.05). Conclusion: SWB provides useful insight into the impact of SLE on psychological health and opportunities to improve quality of life and clinical care.
RESUMO
Objective: The aim of this review is to provide guidance on the selection of approaches to the screening and assessment of enthesitis in patients with spondyloarthritis (SpA). Methods: Twenty-four questions regarding the approaches to the screening and assessment of enthesitis and the implementation details were devised, followed by a systemic literature review. The Grading of Recommendations Assessment, Development, and Evaluation methodology was employed in the development of this guideline, with modifications to evaluate non-interventional approaches under comprehensive consideration of costs, accessibility, and evidence strength. A consensus from the voting panel was required for the inclusion of the final recommendations and the strength of each recommendation. Results: Seventeen recommendations (including five strong recommendations) were included in this guideline. The voting panel expressed unequivocal support for the necessity of screening and assessment of enthesitis in patients with SpA. It was agreed unanimously that symptom evaluation and physical examination should serve as the initial steps to the recognition of enthesitis, whereas Maastricht Ankylosing Spondylitis Enthesitis Score is a reliable tool in both clinical trials and daily medical practice. Ultrasound examination is another reliable tool, with power Doppler ultrasound as an informative addition. Notwithstanding its high resolution, MRI is limited by the costs and relatively low accessibility, whereas radiographs had low sensitivity and therefore should be rendered obsolete in the assessment of enthesitis. PET/CT was strongly opposed in the detection of enthesitis. Conclusion: This guideline provides clinicians with information regarding the screening and assessment of enthesitis in patients with SpA. However, this guideline does not intend on dictating choices, and the ultimate decisions should be made in light of the actual circumstances of the facilities.

INTRODUCTION: Non-specific chronic sialadenitis (NSCS) is a common pathology of labial salivary glands (LSGs), and NSCS with positive anti-SSA/SSB antibodies is common in clinical practice. Previous studies have evaluated the associations of high focus score (FS) with clinical manifestations in primary Sjögren's syndrome (pSS) patients extensively, but the characteristics of pSS with NSCS have seldom been investigated. We here analyzed the characteristics of pSS patients with NSCS. METHODS: Among 425 patients who underwent LSG biopsies, 217 had pSS and 37 non-SS sicca patients had NSCS without other diseases (i.e., sicca controls). We categorized these 217 pSS patients into three groups based on the pathology of LSGs: FS ≥ 1 (n = 104), 0 ≤ FS < 1 (n = 76), and NSCS (n = 37). We then compared the three groups while focusing on the NSCS group. Multivariate logistic regression analysis was performed to identify variables that influenced NSCS. RESULTS: The mean age of pSS patients with NSCS (58.3 ± 11.0 years) was significantly higher than those with FS ≥ 1 (48.5 ± 14.9 years) and 0 ≤ FS < 1 (45.3 ± 13.7 years), but other clinical characteristics were similar. NSCS had a significant positive correlation with age (OR = 7.282, 95% CI 2.085-25.44 and OR = 13.130, 95% CI 3.368-51.189 for patients aged 45-64 years and > 65 years, respectively). Significantly higher levels of lymphocytic infiltration were found in the pSS NSCS group than in the sicca NSCS controls (48.6 vs. 10.8%, respectively). CONCLUSIONS: The pSS patients with NSCS were older than corresponding non-NSCS pSS individuals, but they had similar clinical features. NSCS is associated with age and seldom occurred below the age of 45 years, regardless of the presence or absence of pSS. NSCS may be a subtype of pSS in elderly patients.
RESUMO
OBJECTIVE: To assess the clinical equivalence of TQ-Z2301, a biosimilar of adalimumab, to the reference adalimumab in the treatment of Chinese patients with active ankylosing spondylitis. METHODS: This multicenter, randomized, double-blind, positive-controlled phase III clinical trial was conducted in 19 centers across China. Chinese adults with active ankylosing spondylitis despite being treated with non-steroidal anti-inflammatory drugs for ≥ 4 weeks were randomized in a 1:1 ratio to subcutaneously receive 40 mg of TQ-Z2301 or adalimumab every other week for 24 weeks. The primary endpoint was the percentage of patients who achieved at least 20% improvement according to the Assessment of Spondyloarthritis International Society criteria (ASAS20) at week 24. The equivalence was established if the 90% CI for RR of ASAS20 between two groups at week 24 fell within (0.80, 1.25). Secondary endpoints included efficacy measures of disease activity, spinal mobility, physical function and quality of life, immunogenicity, and pharmacokinetic parameters. Safety analysis was done for all patients who received at least one study drug. RESULTS: A total of 380 patients were enrolled in the study between September 2018 and October 2019, including 188 in the TQ-Z2301 group and 192 in the adalimumab group. In the full analysis population, the ASAS20 response rate at week 24 was 86.70% in the TQ-Z2301 group, and 80.73% in the adalimumab group, the RR of ASAS20 for TQ-Z2301 versus adalimumab was 1.074, 90% CI (0.997, 1.157), fell within the predefined equivalence boundary (0.80, 1.25). Except for the SF-36 at week 12, there was no statistical difference between the two groups for all the secondary endpoints (P>0.05). The incidence of adverse events group was 82.45% in the TQ-Z2301, and 83.85% in the adalimumab group, the safety profile of the two groups was similar. The profiles of immunogenicity and pharmacokinetics were also similar between the two groups. CONCLUSION: TQ-Z2301 is equivalent to adalimumab for the treatment of Chinese patients with active ankylosing spondylitis. The safety, immunogenicity, and pharmacokinetic characteristics of both drugs are similar. TRIAL REGISTRATION: The study (CTR20181863) was registered in the Chinese Clinical Trial Registry on 19 October 2018. Key Points ⢠TQ-Z2301 showed the equivalence of efficacy compared with the reference adalimumab for the treatment of Chinese patients with active ankylosing spondylitis. ⢠The safety, immunogenicity, and pharmacokinetics profiles of TQZ-2301 were similar to those of the reference adalimumab.

OBJECTIVES: The objective of this study is to describe the clinical features of patients with axial spondyloarthritis (axial SpA) in the ChinaSpA registry. METHODS: Patients with clinical diagnosis of ankylosing spondylitis (AS) or axial SpA were enrolled into the registry. Patients with a complete set of pelvis radiograph, pelvis MRI and HLA-B27 (Complete Set group, CS group) were further categorised based on classification criteria into AS, radiographic axial SpA (r-axSpA) and non-radiographic axial SpA (nr-axSpA). Early axial SpA was defined as symptom duration of less than three years. Descriptive statistics were used to describe clinical characteristics of enrolled patients. ANOVA analyses were used to compare patients in different groups. RESULTS: A total of 5270 patients were enrolled in the study, and 3223 patients had complete sets of pelvis radiographs, MRIs and HLA-B27 status. Among them, more than 80% patients met both the ASAS criteria for r-axSpA and the modified New York criteria for AS. Among those with early axial SpA, 92% of patients had sacroiliitis on pelvis radiograph, 3.8% had sacroiliitis only on pelvis MRI, and 3.8% were in the clinical arm without any sacroiliitis on imaging studies. Patients in nr-axSpA clinical arm had less diagnosis delay, lower inflammatory markers and ASDAS, compared topatients in the r-axSpA, nr-axSpA MRI arm. CONCLUSIONS: In the ChinaSpA registry, patients in nr-axSpA clinical arm had the shortest diagnostic delay, lower inflammatory markers and ASDAS, but no difference in extra-articular manifestation, compared to patients in the r-axSpA and nr-axSpA MRI arm.

BACKGROUND: There is heterogeneity in the clinical manifestations and responses to drugs in RA patients due to variety of factors such as genes and environment. Despite advances in the treatment of rheumatoid arthritis (RA), approximately 40% of RA patients still do not achieve primary clinical outcomes in randomized trials, and its low remission rate and high economic consumption remain unresolved, especially in developing countries. Iguratimod (IGU) is a new disease-modifying anti-rheumatic drug (DMARD) with a low price that has demonstrated good efficacy and safety in clinical trials and was approved for active RA in China and Japan. As the most populous country in the Western Pacific region, it is warranted to conduct a study with a large scale of patients in a real-life setting. Our study confirms the new option for RA patients, which is potentially benificial for public health in developing countries. METHODS: This was a nationwide, prospective real-world study of IGU. Eligible subjects were active adult RA patients who aged 18 to 85 with or without multiple comorbidities such as hypertension and diabetes with DMARDs at a stable dosage for at least 12 weeks, or without ongoing DMARDs. A two-stage design was used for this study. In the first stage (the first 12 weeks), IGU 25 mg bid was added as monotherapy or to the background therapy, and in the second stage (the latter 12 weeks), adjustment of RA medicines other than IGU was allowed according to the participants' disease activity. The primary endpoints were American College of Rheumatology 20% response (ACR20) 24 weeks and adverse events during 24 weeks. The secondary endpoints were ACR50 and ACR70 over 24 weeks, the changes of DAS28 and Health Assessment Questionnaire (HAQ) at week 12 and week 24 from baseline. The trial was registered with ClinicalTrials.gov, number NCT01554917. FINDINGS: Between March 2012 and January 2015, 1759 participants were enrolled, of whom 81â¢5% (1433/1759) completed the study. Notably, 1597 patients in the full analysis set were assessed for the effectiveness and 1751 patients were in the safety analysis set; 71â¢9% (1148/1597) of the patients achieved the primary endpoint of ACR20 response at week 24, and 51â¢7% (906/1751) patients had at least 1 adverse event (AE). The incidence of the clinical significant AE (grade≥3) of special interest was 3â¢4% (54 patients for grade 3 and 6 patients for grade 4), and 0â¢7% (13/1751) of patients developed SAEs associated with IGU. The most common clinical significant AEs were infection in 0â¢6% (10/1751) of the patients, abdominal discomfort in 0â¢5% (9/1751) of the patients including 0â¢2% (3/1751) gastric ulcer, fracture in 0â¢4% (7/1751), and increased alanine aminotransferase (ALT) in 0â¢2% (3/1751) of the patients. The secondary endpoint of ACR50 and ACR70 response rates at week 24 were 47â¢4% (757/1597) and 24â¢0% (384/1597). DAS28 was 4â¢11±1â¢27 and 3â¢75±1â¢32 at week 12 and 24, which was significantly decreased -1â¢40±1â¢10 and -1â¢75±1â¢26 compared with baseline (P<0â¢001) respectively. Changes in HAQ at week 12 and 24 from baseline were -7â¢4 ± 9â¢18 and -8â¢5 ± 9â¢97, respectively (all P<0â¢001). Stratified analysis results showed that the patients with shorter disease duration, male gender had better response to IGU. There was no significant difference in ACR20/50/70 responses between elderly patients(≥65 years) and younger patients(<65 years), IGU monotherapy or combined with other DMARDs. However, more fractures (1â¢1% vs 0â¢5%; P = 0â¢64) and infections (8â¢7% vs 7â¢9%; P = 0â¢69) were observed in elderly patients in our study. INTERPRETATION: Our results confirmed the effectiveness and safety of IGU as a new DMARD for active patients with RA as monotherapy or combination therapy. FUNDING: This study was supported by "the 11th Five-Year-Plan for Science and Technology Support Program (2012ZX09104-103-01)".
RESUMO
OBJECTIVE: Pulmonary arterial hypertension (PAH) is a life-threatening complication of systemic lupus erythematosus (SLE). However, there is no algorithm to identify those at high risk. This study was undertaken to develop a prediction model for PAH in patients with lupus that provides individualized risk estimates. METHODS: A multicenter, longitudinal cohort study was undertaken from January 2003 to January 2020. The study collected data on 3,624 consecutively evaluated patients diagnosed as having SLE. The diagnosis of PAH was confirmed by right-sided heart catheterization. Cox proportional hazards regression and least absolute shrinkage and selection operator were used to fit the model. Model discrimination, calibration, and decision curve analysis were performed for validation. RESULTS: Ninety-two lupus patients (2.54%) developed PAH during a median follow-up of 4.84 years (interquartile range 2.42-8.84). The final prediction model included 5 clinical variables (acute/subacute cutaneous lupus, arthritis, renal disorder, thrombocytopenia, and interstitial lung disease) and 3 autoantibodies (anti-RNP, anti-Ro/SSA and anti-La/SSB). A 10-year PAH probability-predictive nomogram was established. The model was internally validated by Harrell's concordance index (0.78), the Brier score (0.03), and a satisfactory calibration curve. According to the net benefit and predicted probability thresholds, we recommend annual screening in high-risk (>4.62%) lupus patients. CONCLUSION: We developed a risk stratification model using routine clinical assessments. This new tool may effectively predict the future risk of PAH in patients with SLE.

OBJECTIVES: This study aimed to investigate the associated factors of myocardial involvements (MIs) in patients with idiopathic inflammatory myopathies (IIMs). METHODS: In this multi-center cross-sectional study, 1946 patients with IIMs were enrolled from Chinese Rheumatism Data Center-Myositis Registry (CRDC-MYO). A total of 108 (5.5%) patients were identified with MIs, including congestive heart failure (n = 67, 62.0%), and severe arrhythmias (n = 61, 56.5%). The other 1838 IIM patients without IMs were set as the control group. Clinical features were collected including age, gender, comorbidities, clinical symptoms, clinical signs of both IIMs and MIs, lab findings including myositis-specific antibodies (MSAs) and myositis-associated antibodies (MAAs), echocardiogram, and radiological exams. Multivariate logistic analysis was used to explore independent associated factors of MIs in patients with IIMs. RESULTS: Several independent associated factors were identified in multi-variate logistic regression, including positivity for anti-mitochondrial antibody-subtype 2 (AMA-M2) (OR 5.194, 95% CI 2.509-10.753, P < 0.001), elevation of creatine kinase (CK) (OR 2.611, 95% CI 1.312-5.198, P = 0.006), elevation of C-reactive protein (CRP) (OR 2.150, 95% CI 1.211-3.818, P = 0.001), and pulmonary hypertension (OR 4.165, 95% CI 1.765-9.882, P = 0.009). AMA-M2 and pulmonary hypertension were the most consistent associated factors in the polymyositis subgroup and the dermatomyositis/clinically amyopathic dermatomyositis subgroup. CONCLUSIONS: MIs are rare but serious complication of IIMs could lead to congestive heart failure and severe arrhythmias. IIM patients with AMA-M2 positivity, elevation of CK and CRP, and pulmonary hypertension are more likely to develop MI complications. Key Points ⢠This study investigated the independent associated factors for clinically significant myocardial involvements among idiopathic inflammatory myopathies in a large-scale, nation-wide multi-center cross-sectional study.

One of the hallmarks of primary Sjogren's syndrome (pSS) is the presence of various autoantibodies in patients' serum, including traditional autoantibodies for disease diagnosis and classification, autoantibodies associated with other autoimmune diseases, and the novel autoantibodies identified from mouse models. The autoantibodies are closely related to the diagnosis, prognosis, and clinical manifestations of pSS. There are significant differences in the prevalence and clinical correlations between anti-Ro60 antibody and anti-Ro52 antibody. Also, the novel autoantibodies play an important role in the diagnosis and classification of pSS. These advances further improve the accuracy of pSS diagnosis and provide references for basic and clinical research.

Takayasu arteritis (TA) is a kind of large-vessel vasculitis that mainly affects the aorta and its branches, and the patients are usually women at a relatively young age. The chronic inflammation of arteries in TA patients leads to stenosis, occlusion, dilatation, or aneurysm formation. Patients with TA thereby have a high risk of cardiovascular disease (CVD) complications, which are the most common cause of mortality. This review summarizes the main cardiovascular complications and the risk factors of cardiovascular complications in patients with TA. Here, we discuss the benefits and potential risks of physical exercise in patients with TA and give recommendations about exercise prescription for TA patients to decrease the risks of CVD and facilitate rehabilitation of cardiovascular complications, which might maximally improve the outcomes.
RESUMO
INTRODUCTION: The aim of this work is to examine the efficacy and safety of prefilled liquid etanercept-biosimilar Yisaipu versus lyophilized Yisaipu in active ankylosing spondylitis (AS) patients. METHODS: This double-blind, phase III trial with non-inferiority design randomized adult patients with active AS in a 3:1:1 ratio to receive twice-weekly 25-mg prefilled liquid Yisaipu for a total of 48 injections (group I, n = 330), once-weekly 50-mg prefilled liquid Yisaipu for 24 injections (group II, n = 110), or twice-weekly 25-mg lyophilized Yisaipu for 48 injections (group III, n = 110). Both physicians and patients who received 25-mg twice-weekly lyophilized or liquid Yisaipu were blinded to treatment assignment while patients who received 50-mg once-weekly liquid Yisaipu received treatment in an open-label design. In addition, 90 patients in the PK/PD study were randomized in a 1:1:1 ratio to each group. The primary outcome was the proportion of patients who achieved ASAS20 at week 24. RESULTS: A total of 640 subjects were enrolled. The proportion of patients who attained ASAS20 at week 24 was 85.56% in group I, 85.71% in group II, and 83.45% in group III (group I vs. III, P = 0.545; group II vs. III, P = 0.605). The difference between group I and III was 2.10% (95% CI - 5.06%, 9.27%) and 2.26% (95% CI - 6.21%, 10.73%) between group II and III, meeting the non-inferiority threshold (Δ = - 15%) (P < 0.001). Except for a statistical difference between group I (75.83%) and group III at week 8 (64.75%, P = 0.011), there was no statistical difference in the ASAS20 attainment rate among the three groups at other time points. The incidence of serious adverse events was comparable among the three groups (group I, 2.50%, II, 2.86% and III, 1.43%; P > 0.05). No deaths were reported. CONCLUSIONS: Once-weekly 50-mg or twice-weekly 25-mg prefilled liquid Yisaipu is safe and non-inferior to twice-weekly 25-mg lyophilized Yisaipu. TRIAL REGISTRATION: CTR20130124 and NCT04345458.
