ABSTRACT
BACKGROUND: Serologically active clinically quiescent (SACQ) is a state within systemic lupus erythematosus (SLE) characterized by elevated serologic markers without clinical activity. The heterogeneity in SACQ patients poses challenges in disease management. This multicenter prospective study aimed to identify distinct SACQ subgroups and assess their utility in predicting organ damage. METHODS: SACQ was defined as a sustained period of at least 6 months with persistent serologic activity, marked by positive anti-double-stranded DNA (dsDNA) antibodies and/or hypocomplementemia, and without clinical activity. Cluster analysis was employed, utilizing 16 independent components to delineate phenotypes. FINDINGS: Among the 4,107 patients with SLE, 990 (24.1%) achieved SACQ within 2.0 ± 2.3 years on average. Over a total follow-up of 7,105.1 patient years, 340 (34.3%) experienced flares, and 134 (13.5%) developed organ damage. Three distinct SACQ subgroups were identified. Cluster 1 (n = 219, 22.1%) consisted predominantly of elderly males with a history of major organ involvement at SLE diagnosis, showing the highest risk of severe flares (16.4%) and organ damage (27.9%). Cluster 2 (n = 279, 28.2%) was characterized by milder disease and a lower risk of damage accrual (5.7%). Notably, 86 patients (30.8%) in cluster 2 successfully discontinued low-dose glucocorticoids, with 49 of them doing so without experiencing flares. Cluster 3 (n = 492, 49.7%) featured the highest proportion of lupus nephritis and a moderate risk of organ damage (11.8%), with male patients showing significantly higher risk of damage (hazard ratio [HR] = 4.51, 95% confidence interval [CI], 1.82-11.79). CONCLUSION: This study identified three distinct SACQ clusters, each with specific prognostic implications. This classification could enhance personalized management for SACQ patients. FUNDING: This work was funded by the National Key R&D Program (2021YFC2501300), the Beijing Municipal Science & Technology Commission (Z201100005520023), the CAMS Innovation Fund (2021-I2M-1-005), and National High-Level Hospital Clinical Research Funding (2022-PUMCH-D-009).
ABSTRACT
OBJECTIVES: The predominant determinant of an unfavorable prognosis among Systemic Lupus Erythematosus (SLE) patients resides in the irreversible organ damage. This prospective cohort study aimed to identify the additional value of anti-nucleosome antibodies on organ damage accumulation in SLE patients. METHODS: Based on the Chinese SLE Treatment and Research group (CSTAR) registry, demographic characteristics, autoantibodies profiles, and clinical manifestations were collected at baseline. Follow-up data were collected by reviewing clinical records. RESULTS: Of 2481 SLE patients with full follow-up data, 663 (26.7%) were anti-nucleosome antibodies positive and 1668 (68.0%) were anti-dsDNA antibodies positive. 764 (30.8%) patients developed new organ damage during a mean follow-up of 4.31 ± 2.60 years. At baseline, patients with positive anti-nucleosome antibodies have a higher rate of lupus nephritis (50.7% vs 36.2%, p < .001). According to the multivariable Cox regression analysis, both anti-nucleosome (HR = 1.30, 95% CI, 1.09-1.54, p < .001) and anti-dsDNA antibodies (HR=1.68, 95% CI, 1.38-2.05, p < .001) were associated with organ damage accumulation. Anti-nucleosome (HR = 2.51, 95% CI, 1.81-3.46, p < .001) and anti-dsDNA antibodies (HR = 1.69, 95% CI, 1.39-2.06, p < .001) were independent predictors for renal damage. Furthermore, the combination of the two antibodies can provide more accurate information about renal damage in overall SLE patients (HR = 3.19, 95% CI, 2.49-4.10, p < .001) and patients with lupus nephritis at baseline (HR = 2.86, 95% CI, 2.29-3.57, p < .001). CONCLUSION: Besides anti-dsDNA antibodies, anti-nucleosome antibodies can also provide information about organ damage accrual during follow-up. The ability of co-positivity of anti-nucleosome and anti-dsDNA antibodies in predicting renal damage may lead to additional benefits in the follow-up of these patients.

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: Early detection of neuropsychiatric systemic lupus erythematosus (NPSLE) remains a challenge in clinical settings. Previous studies have found different autoantibodies as markers for NPSLE. This study aimed to describe the distribution of psychiatric syndromes in a group of patients with systemic lupus erythematosus (SLE) and to investigate the association between psychiatric syndromes and specific autoantibodies. Methods: This retrospective study was conducted at a single medical center in China. We reviewed medical records of hospitalized patients with SLE who were consulted by psychiatrists due to potential mental disorders. Results of serum autoantibodies and general laboratory tests were collected. The correlation between clinical variables was examined. Binary logistic regression analyses were used to determine factors related to NPSLE and different psychiatric diagnoses. Results: Among the 171 psychiatric manifestations in 160 patients, 141 (82.4%) were attributed to SLE. Acute confusional state (ACS) had the highest prevalence (57.4%). Anti-cardiolipin (ACL) antibody (X2 = 142.261, p < 0.001) and anti-ß2 glycoprotein I (-ß2GP1) antibody (X2 = 139.818, p < 0.001) varied significantly between groups, with the highest positive rate found in patients with mood disorders (27.3% and 18.2%). SLE disease activity index - 2000 (SLEDAI-2K) score excluding item ACS and item psychosis was a predictor of NPSLE (OR 1.172 [95% CI 1.105 - 1.243]). Conclusions: Disease activity reflected by SLEDAI-2K score is a predictor for NPSLE. Antiphospholipid antibodies are associated with mood disorders in SLE. Further separate investigation of neuropsychiatric disorders is needed in order to better comprehend NPSLE's pathological mechanism.

BACKGROUND: To investigate the role of antiphospholipid antibodies (aPLs) in the disease severity and prognosis of SLE-related thrombocytopenia (SLE-TP). METHODS: This multicenter prospective study was conducted based on data from the CSTAR registry. TP was defined as a platelet count<100 × 109/L. Demographic characteristics, platelet count, clinical manifestations, disease activity, and autoantibody profiles were collected at baseline. Relapse was defined as the loss of remission. Bone marrow aspirate reports were also collected. RESULTS: A total of 350 SLE-TP patients with complete follow-up data, 194 (55.4%) were aPLs positive. At baseline, SLE-TP patients with aPLs had lower baseline platelet counts (61.0 × 109/L vs. 76.5 × 109/L, P<0.001), and a higher proportion of moderate to severe cases (24.2% vs. 14.1% ; 18.0% vs. 8.3%, P<0.001). SLE-TP patients with aPLs also had lower platelet counts at their lowest point (37.0 × 109/L vs. 51.0 × 109/L, P = 0.002). In addition, thean increasing number of aPLs types was associated with a decrease in the baseline and minimum values of platelets ( P<0.001, P = 0.001). During follow-up, SLE-TP carrying aPLs had a higher relapse rate (58.2% vs. 44.2%, P = 0.009) and a lower complete response (CR) rate. As the types of aPLs increased, the relapse rate increased, and the CR rate decreased. Furthermore, there was no significant difference in the ratio of granulocytes to red blood cells (G/E), the total number of megakaryocyte and categories. CONCLUSION: SLE-TP patients with positive aPLs had more severe disease a lower remission rate but a higher relapse rate.

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.
ABSTRACT
Introduction: We aimed to evaluate the risk factors for the development of deep vein thrombosis (DVT) within one month after delivery in pregnant women of advanced maternal age undergoing cesarean section and explore the predictive value of fasting coagulation indicators in relation to the development of DVT. Methods: A total of 176 eligible postpartum women were included in this study. Sixty-seven cases developed DVT within one month after delivery (DVT group), while 109 cases did not experience DVT (NDVT group). Within 24 hours after cesarean section, fasting coagulation indicators are measured. Coagulation system analysis was performed using the STA-R Evolution fully automated coagulation analyzer. Results: The women who developed DVT were found to be older, had a higher proportion of women with previous childbirth experiences, and had a higher proportion of women with comorbidities. Our results revealed significant differences in the levels of activated partial thromboplastin time and prothrombin time between the NDVT group and the DVT group. In contrast, the DVT group displayed significantly higher levels of D-dimer, plasma fibrinogen and platelet count when compared to the NDVT group. The AUC for the combined test model was substantially higher compared to individual parameters. Discussion: Multiple parameters of the postoperative coagulation state in the combined test model provided a more accurate prediction of DVT occurrence in elderly pregnant women after cesarean section.
ABSTRACT
OBJECTIVE: To evaluate the efficacy and safety of telitacicept in adult patients with primary SS (pSS) in a phase II randomized double-blind placebo-controlled trial. METHODS: Patients with pSS with positive anti-SSA antibody and ESSDAI ≥ 5 were randomly assigned, in a 1:1:1 ratio, to receive weekly subcutaneous telitacicept 240 mg, 160 mg, or placebo for 24 weeks. The primary end point was the change from baseline in the ESSDAI at week 24. Safety was monitored. RESULTS: A total of 42 patients were enrolled and randomized (n = 14 per group). Administration of telitacicept 160 mg resulted in a significant reduction in ESSDAI score from baseline to week 24 compared with placebo (P < 0.05). The placebo-adjusted least-squares mean change from baseline was -4.3 (95% CI -7.0, -1.6; P = 0.002). While, mean change of ESSDAI in telitacicept 240 mg was -2.7(-5.6-0.1) with no statistical difference when compared that in placebo group (P = 0.056). In addition, MFI-20 and serum immunoglobulins decreased significantly (P < 0.05) at week 24 in both telitacicept groups compared with placebo. No serious adverse events were observed in the telitacicept treating group. CONCLUSION: Telitacicept showed clinical benefits and good tolerance and safety in the treatment of pSS.

BACKGROUND: Janus kinase (JAK) inhibitors have been proven to be effective and safe in various autoimmune diseases. However, there is still a lack of comprehensive evidence regarding their efficacy and safety in systemic and cutaneous lupus erythematosus. METHODS: We searched for systemic and cutaneous lupus erythematosus patients who were treated with JAK inhibitors in PubMed, Embase, Web of Science, and the Cochrane Library until February 28, 2023. The quality of clinical trials was assessed using the Cochrane risk-of-bias tool. Meta-analysis was conducted when at least three studies had comparable measures of outcome. If meta-analysis was not feasible, a descriptive review was carried out. RESULTS: We included 30 studies, consisting of 10 randomized controlled trials and 20 case series or reports, with a total of 2,460 patients. JAK inhibitors were found to be more effective than placebo in systemic lupus erythematosus (SLE) based on the percentage of achieving SLE Responder Index (SRI)-4 response (RR = 1.18; 95% CI 1.07 to 1.31; p = 0.001), British Isles Lupus Assessment Group -based Composite Lupus Assessment (BICLA) response (RR = 1.16; 95% CI 1.02 to 1.31; p = 0.02), Lupus Low Disease Activity State (LLDAS) (RR = 1.28; 95% CI 1.07 to 1.54; p = 0.008), and Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2 K) remission of arthritis or rash (RR = 1.09; 95% CI 1.00 to 1.18; p = 0.04), particularly in treating musculoskeletal and mucocutaneous involvement. However, the effect of JAK inhibitors on cutaneous lupus erythematosus was uncertain. JAK inhibitors and placebo had a similar incidence of adverse events (RR = 1.01; 95% CI 0.97 to 1.04; p = 0.65). CONCLUSION: JAK inhibitors could be a potential treatment option for systemic and cutaneous lupus erythematosus, particularly in treating cutaneous and musculoskeletal lesions of SLE. JAK inhibitors had a safe profile.

Objective: This study aimed to identify the presence of psychiatric comorbidities as well as investigate the relationship between psychiatric interventions for mental symptoms and mortality in patients with systemic lupus erythematosus (SLE). Method: We retrospectively evaluated the records of 160 inpatients with SLE who required psychiatric consultation for further therapeutic intervention from 2013 to 2020 in a tertiary general hospital. We collected clinical data, including diagnoses, medications, and mortality rate. We compared clinical characteristics among the diagnosis groups and correlations between variables. Results: A total of 138 (86.3%) patients met the diagnostic criteria for at least one mental disorder, with the most common being delirium (54.4%). The average Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score significantly differed among the diagnosis groups (p = 0.003). The mortality rate among patients with delirium was significantly higher than that in the other patient groups (x2 = 12.967, p = 0.024). SLEDAI-2K score was not significantly correlated with mortality (r = 0.123, p = 0.087). Antipsychotics use was associated with mortality (odds ratio 0.053, p = 0.021). Conclusion: Antipsychotic use may decrease death risk for patients with NPSLE. Early psychiatric consultation is necessary for patients with SLE who have developed or have suspected psychiatric symptoms in order to establish a comprehensive intervention plan.
ABSTRACT
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.

OBJECTIVES: To investigate potential predictors of treatment response in primary Sjögren's syndrome (pSS) patients with severe immune thrombocytopenia (ITP), with a focus on bone marrow megakaryocyte (MK) count. METHODS: This case-control study included patients with pSS and severe ITP who were admitted to Peking Union Medical College Hospital and met the 2002 AECG or 2016 American College of Rheumatology / European League Against Rheumatism criteria for SS. Patients who had overlap other connective tissue diseases and with thrombocytopenia that could be explained by other causes were excluded. Severe ITP was defined as platelet count <20 × 109 /L. Response was evaluated at 3 months after treatment. RESULTS: Sixty-eight eligible patients were included: 34 (50%) achieved complete remission (CR), 18 (26%) partial remission (PR) and 16 (24%) were non-responders (NRs). Fewer infections were found in the CR group (24%) than in the PR (50%) and NR (56%) groups (P = 0.04). The MK count (CR 32 vs PR 36 vs NR 4 per slide, P < 0.001) in the NR group was significantly lower than in the other groups. MK count >6.5 per slide predicted good treatment response, with 85.7% sensitivity, 88.1% specificity and 0.866 area under the curve. Logistic regression indicated that patients with more MKs were more likely to respond to immunotherapy (crude odds ratio [OR] 1.45, 95% CI 1.2-2.0, adjusted OR 1.68, 95% CI 1.2-2.7). CONCLUSIONS: MK count predicted response to immunosuppressive treatment in pSS patients with severe ITP. These patients are recommended to have bone marrow aspiration before treatment initiation. Clinicians should be aware of screening for infections during clinical practice.

OBJECTIVES: The study aimed to identify clinical characteristics in Chinese patients with psoriatic arthritis (PsA) with or without a family history of psoriasis and/or PsA. METHODS: Patients with PsA were recruited based on Chinese REgistry of Psoriatic ARthritis (CREPAR) between December 2018 and June 2021. The demographics, clinical information relating to PsA, laboratory variables and comorbidities were collected. The association between family history of psoriatic disease and clinical characteristics on PsA was analysed using logistic regression analysis. RESULTS: Among 1074 eligible patients with PsA, 313 (29.1%) had a family history of psoriasis and/or PsA. Compared with patients without a family history, notably, patients with a family history of psoriasis and/or PsA had an earlier age of onset of psoriasis and PsA, higher proportions of enthesitis and nail involvement, a higher prevalence of positive human leukocyte antigen-B27 (HLA-B27), lower disease activity score 28-erythrocyte sedimentation rate, higher proportions of hyperlipidaemia, lower proportions of hypertension and diabetes. Furthermore, after adjusting for confounding factors, logistic regression analysis demonstrated that a positive family history of psoriasis and/or PsA was associated with more females (OR 1.514, 95% CI 1.088-2.108, p=0.014), earlier age at psoriasis onset (OR 0.971, 95%CI 0.955-0.988, p=0.001), a higher prevalence of HLA-B27 (OR 1.625 95%CI 1.089-2.426, p=0.018), more presence of nail involvement (OR 1.424, 95%CI 1.007-2.013, p=0.046) and enthesitis (OR 1.393, 95%CI 1.005-1.930, p=0.046), a higher proportion of hyperlipidaemia (OR 2.550, 95%CI 1.506-4.317, p=0.001) in PsA patients. CONCLUSIONS: This was first nationwide study to characterize patients with and without a family history of psoriatic disease in China. The findings from the present study revealed that family history of psoriasis and/or PsA had greater effects on disease phenotypes of PsA, especially nail disease and enthesitis.

OBJECTIVE: The pilot study aims to evaluate the effectiveness and safety of baricitinib in Behcet's Disease (BD) patients with refractory vascular involvement. METHODS: We consecutively enrolled vascular/cardiac BD patients who received baricitinib (2 mg/day) along with glucocorticoids (GCs) and immunosuppressants in our center. Efficacy assessment mainly depends on the proportion of clinical remission and side effects were recorded. RESULTS: 17 patients (12 males) were included with a mean follow-up of 10.7 ± 5.3 months. At 3 months of follow-up, 76.5% of patients achieved a complete response and the proportion increased to 88.2% at the last visit. During follow-up, ESR (p < 0.01) and hsCRP (p < 0.0001) decreased significantly, as well as Behçet's Disease Current Activity Form score (p < 0.01). In addition, baricitinib showed a GCs-sparing effect. No serious adverse events were noted. CONCLUSIONS: Our study suggests that baricitinib is well-tolerated and effective in treating refractory vascular/cardiac BD patients.

OBJECTIVES: This study aimed to investigate the clinical characteristics, outcomes, and associated factors of patients with systemic lupus erythematosus-associated diffusive alveolar hemorrhage (SLE-DAH) stratified by infection status in a national representative cohort. METHODS: This single-center retrospective study included 124 consecutive patients with SLE-DAH in a tertiary care center between 2006 and 2021. The diagnosis of DAH was made based on a comprehensive evaluation of clinical manifestations, laboratory and radiologic findings, and bronchoalveolar lavage. Demographics, clinical features, and survival curves were compared between patients with bacterial, non-bacterial, and non-infection groups. Univariate and multivariate logistic regression analyses were performed to determine the factors independently associated with bacterial infection in SLE-DAH. RESULTS: Fifty-eight patients with SLE-DAH developed bacterial infection after DAH occurrence, thirty-two patients developed fungal and/or viral infection, and thirty-four patients were categorized as non-infection. The bacterial infection group have a worse prognosis (OR 3.059, 95%CI 1.469-6.369, p = 0.002) compared with the other two groups, with a mortality rate of 60.3% within 180 days after DAH occurrence. Factors independently associated with bacterial infections in SLE-DAH included hematuria (OR 4.523, 95%CI 1.068-19.155, p = 0.040), hemoglobin drop in the first 24 h after DAH occurred (OR 1.056, 95%CI 1.001-1.115, p = 0.049), and anti-Smith antibody (OR 0.167, 95%CI 0.052-0.535, p = 0.003). Glucocorticoid pulse therapy and cyclophosphamide were administered in more than 50% of patients regardless of their infectious status. According to clinical experience at our hospital and in previous studies, we recommended a comprehensive management algorithm for SLE-DAH based on infection stratification. CONCLUSION: Infection, especially bacterial infection, is a severe complication and prognostic factor of SLE-DAH. Comprehensive management strategies, including diagnosis, evaluation, treatment, and monitoring, based on infection stratification may fundamentally improve outcomes of patients with SLE-DAH. Key Points ⢠Bacterial infection is an important, but neglected, prognosis factor of systemic lupus erythematosus (SLE)-associated diffusive alveolar hemorrhage (DAH). ⢠Hematuria, hemoglobin drop, and anti-Smith antibody can independently predict bacterial infections in SLE-DAH. ⢠We put forward a comprehensive management algorithm based on infection stratification for SLE-DAH.

BACKGROUND: Many patients with polyarteritis nodosa (PAN) complicated by digital gangrene have poor outcomes and related research information is limited. Our aim is to identify the associated risk and prognostic factors in PAN patients with digital gangrene. PATIENTS AND METHODS: We conducted a retrospective study of 148 PAN patients admitted to Peking Union Medical College Hospital from Octorber 2001 to December 2018. Forty-seven (31.8%) PAN patients had digital gangrene. The average age was 40.4 ± 17.9 years. RESULTS: The presence of digital gangrene was correlated with current smoking (P = .008, odds ratio [OR] 2.99, 95% CI, 1.33-6.73), eosinophil elevation (P = .003, OR 4.21, 95% CI, 1.62-10.91) and elevated leukocytes (P = .001, OR 4.26, 95% CI, 1.86-9.78). Thirty-two (68.1%) gangrene patients received methylprednisolone pulse therapy and all of these patients were treated with cyclophosphamide. Nine patients suffered irreversible organ injury and 2 died. Survival analysis showed higher serum C-reactive protein (CRP) was associated with poor prognosis in patients with gangrene (log-rank P = 0.042 and generalized Wilcoxon P = .020). CONCLUSIONS: PAN patients with current smoking and eosinophil elevation were more prone to digital gangrene and a high serum CRP level predicted poor outcomes. The CRP level should be efficiently controlled to ensure a good prognosis.

Background Synovial hypoxia is a hallmark of rheumatoid arthritis (RA). Photoacoustic (PA) imaging, based on the use of laser-generated US, can detect the oxygenation status of tissue in individuals with RA. However, large studies are lacking, with few investigating the correlation between oxygenation status and disease activity. Purpose To measure synovial oxygenation status in participants with RA by using a multimodal PA US imaging system and to determine the correlation between PA imaging-measured oxygen saturation (SO2) and disease activity. Materials and Methods In this prospective observational cohort study, multimodal PA US imaging examinations were performed on small joints of consecutive participants with RA, who were treated at two outpatient rheumatology clinics from 2019 to 2021, and healthy controls. The SO2 values of the synovium were measured with dual-wavelength PA imaging and classified into three categories-hyperoxia, intermediate oxygenation status, or hypoxia-based on the signal coloration and clustering analysis of the SO2 values. The correlations of oxygenation status with power Doppler US (PDUS) scoring and clinical disease activity index were evaluated with one-way analysis of variance and the Kruskal-Wallis test with Bonferroni correction. Results A total of 118 participants with RA (median age, 55 years [IQR, 41-62 years]; 92 women) and 15 healthy control participants (median age, 37 years [IQR, 33-41 years]; 11 women) were included. The wrist synovium was categorized as hyperoxic in 36 participants with RA, of intermediate oxygenation status in 48 participants, and hypoxic in 34 participants. All control participants had hyperoxic synovial tissues. For participants with RA, hyperoxic synovium had more affluent Doppler US-depicted vasculature than those with hypoxia and intermediate oxygenation status (mean PDUS grade: hyperoxia, 2.7 ± 0.6 [SD]; intermediate, 1.3 ± 0.7; hypoxia, 1.1 ± 0.8; P < .001). Participants with intermediate status synovium had a lower clinical disease activity index than those with hypoxia (intermediate, 11.0 [IQR, 5.0-21.5] vs hypoxia, 26.0 [IQR, 18.0-39.0]; P = .001). Conclusion Photoacoustic imaging-detected hypoxia in thickened synovium correlated with less vascularization and higher disease activity in participants with rheumatoid arthritis.

Neuropsychiatric systemic lupus erythematosus (NPSLE) has a broad spectrum of subtypes with diverse severities and prognoses. Ischemic and inflammatory mechanisms, including autoantibodies and cytokine-mediated pathological processes, are key components of the pathogenesis of NPSLE. Additional brain-intrinsic elements (such as the brain barrier and resident microglia) are also important facilitators of NPSLE. An improving understanding of NPSLE may provide further options for managing this disease. The attenuation of neuropsychiatric disease in mouse models demonstrates the potential for novel targeted therapies. Conventional therapeutic algorithms include symptomatic, anti-thrombotic, and immunosuppressive agents that are only supported by observational cohort studies, therefore performing controlled clinical trials to guide further management is essential and urgent. In this review, we aimed to present the latest pathogenetic mechanisms of NPSLE and discuss the progress in its management.
