Background: The risk of non-Hodgkin's lymphoma in patients with primary Sjögren's syndrome (pSS) is well established. However, the association between pSS and the risk of gastrointestinal cancers remains underexplored. This study aims to assess the risk of gastrointestinal cancers in pSS patients in Korea compared with the general population.
Methods: We included 320,082 participants from National Health Insurance Service-National Sample Cohort (NHIS-NSC) database. Of these, there were 850 patients with pSS and 319,232 in the non-pSS group. All participants were followed-up until 2019 or the development of gastrointestinal cancers, whichever occurred first. Hazard ratio (HR) and 95% confidence intervals (95% CI) for gastrointestinal cancers were calculated by multivariable Cox proportional hazards models.
Results: Compared with the non-pSS group, patients with pSS had a higher risk of developing all gastrointestinal cancers, but the association did not reach statistical significance (adjusted HR: 1.240, 95% CI: 0.990-1.543). Site-specific analyses showed that pSS patients had a higher risk of colorectal cancer (adjusted HR: 1.597, 95% CI: 1.122-2.273) and pancreatic cancer (adjusted HR: 2.294, 95% CI: 1.267-4.151). The association was found to be more prominent in females and elderly (aged ≥ 60) individuals according to subgroup analyses.
Conclusions: pSS was associated with increased risks of colorectal and pancreatic cancers, particularly among females and older adults. Further research should explore the underlying mechanisms and the impact of pSS duration and severity on cancer risk.

This study aimed to investigate whether discontinuation of biological or targeted synthetic antirheumatic disease-modifying drugs (bDMARDs or tsDMARDs) influences the incidence of postoperative complications in patients with rheumatoid arthritis (RA) undergoing orthopedic surgery. A retrospective multicenter cohort study including patients receiving bDMARDs or tsDMARDs who underwent orthopedic surgery was conducted. Data collected encompassed the duration of drug discontinuation and postoperative adverse events, such as delayed wound healing, surgical site infection (SSI), disease flare-ups, and mortality. The association between drug discontinuation and these outcomes was analyzed. Multivariate analyses were conducted to identify potential risk factors for these events. A total of 2,060 cases were initially enrolled. After applying inclusion and exclusion criteria, data from 1,953 patients were analyzed. No significant differences were observed between the groups regarding delayed wound healing, SSI, or mortality. However, the incidence of disease flare-ups was substantially higher in the drug discontinuation group and in the interleukin (IL)-6 inhibitor group. Multivariate analysis identified that tumor necrosis factor α and IL-6 inhibitor use was associated with a higher risk of delayed wound healing relative to T-cell function modifiers. In orthopedic surgery for patients with RA, maintaining the standard or the half of administration interval of bDMARD appears safe in the preoperative period. However, the drug discontinuation may increase the risk of postoperative flare-ups, particularly with IL-6 inhibitors. In addition, T-cell function modifiers may be associated with a lower risk of delayed wound healing, suggesting their safety profile in this context.

Studies have documented that exercise programs have symptomatic relief benefits for ankylosing spondylitis patients. It has also been reported that MGF (Mechanical/Mechano Growth Factor) and related gene expressions can be stimulated by certain exercises. In this study, we explored the possible role(s) MGF could play in controlling arthritis and ankylosing spondylitis-like symptoms in HLA-B27/Hu-β2m transgenic rats. HLA-B27/ Hu-β2m transgenic rats were inoculated with inactivated Mycobacterium tuberculosis to induce arthritis and ankylosing spondylitis, followed by MGF treatment for seven weeks. The animal models were monitored for the onset, severity, and progression of clinical symptoms. Our results indicated a dose-dependent increase in the time of onset of arthritis symptoms from 14 days in the control group to 23 days in the high-dose MGF group. Our results also indicated a dose-dependent increase in the anti-inflammatory cytokines IL-2 and IL-10 and decrease in the pro-inflammatory cytokine TNF-α in the peripheral circulation and in bony infiltrations. Likewise, there was a dose-dependent inhibition of STAT3 (signal transducer and activator of transcription 3) and RORγt (retinoic acid-related orphan receptor gamma-t) expression, which was further confirmed by the inhibition of IL-17 expression. From the results of our study, it can be concluded that MGF controlled inflammation and inhibited bone erosion and syndesmophyte formation in HLA-B27/Hu-β2m transgenic rats by stimulating IL-2 and IL10 production while downregulating TNF-α, STAT3, RORγt, and IL-17 expression in a dose-dependent manner, leading to a significant reduction in arthritis and AS-like clinical symptoms.

This study aimed to evaluate the therapeutic effects of Omentin-1 on osteoarthritis and explore its protective mechanisms. Two osteoarthritis mouse models were created: wild-type and SIRT6−/−. After five weeks of Omentin-1 injection, we evaluated M1 and M2 macrophage distribution in the mouse synovium and measured inflammatory factor levels. Matrix proteins related to cartilage repair were detected, and safranin O-green and toluidine blue staining were used to evaluate the repair. Furthermore, we evaluated how Omentin-1 regulated macrophage polarization and explored potential mechanisms. Omentin-1 was low in osteoarthritis mice and linked to M1 macrophage polarization. It protected these mice by reducing synovial inflammation, decreasing M1 macrophages, increasing M2 macrophages, and lowering pro-inflammatory factors while raising anti-inflammatory factors and minimizing inflammatory cell infiltration in the synovium. Omentin-1 enhanced Collagen II and α-SMA expression in cartilage, aiding repair. Further mechanistic studies indicated that Omentin-1 can enhance the expression of SIRT6 in the joint tissues of mice with osteoarthritis. Omentin-1’s inhibition of inflammation in osteoarthritis mice was linked to SIRT6. Elevated Omentin-1 levels can mitigate the inflammatory response in osteoarthritis by enhancing SIRT6 expression, inhibiting inflammatory factors, suppressing M1 macrophages, and increasing M2 macrophages.

Elevated Omentin-1 levels can mitigate the inflammatory response in osteoarthritis by enhancing SIRT6 expression, inhibiting inflammatory factors, suppressing M1 macrophages, and increasing M2 macrophages.","PeriodicalId":8419,"journal":{"name":"Arthritis Research & Therapy","volume":"17 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145535327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Anti-melanoma differentiation-associated gene 5-positive dermatomyositis (anti-MDA5 + DM) is a unique subtype of idiopathic inflammatory myopathy (IIM) with a poorer prognosis. The immune-metabolic landscape underlying anti-MDA5 + DM pathogenesis remains poorly defined. In our study, we integrated metabolomic profiling of plasma and peripheral blood mononuclear cells (PBMCs) in anti-MDA5 + DM. This study enrolled 183 patients with IIM and 104 healthy controls (HCs), comprising a discovery cohort of 150 patients (67 anti-MDA5 + DM patients and 83 anti-MDA5- IIM patients serving as disease controls) and 71 HCs, as well as a validation cohort of 33 patients and 33 HCs. To establish a robust diagnostic model, we implemented a dual analytical approach: seven machine learning algorithms were initially employed to identify key differentially expressed metabolites (DEMs), followed by LASSO regression analysis for optimal feature selection and model construction. Decision curve analysis (DCA) was subsequently conducted to assess their clinical applicability in decision-making scenarios. DHEAS and citrate in plasma were validated using enzyme-linked immunosorbent assay (ELISA) and biochemical assay, respectively. Non-targeted metabolomic profiling of plasma identified 90DEMs distinguishing anti-MDA5 + DM patients from HCs, including 65 upregulated and 25 downregulated metabolites. Pathway enrichment analysis revealed the predominant involvement of these plasma DEMs in beta-alanine metabolism. PBMC-derived targeted metabolomics identified 41 DEMs in anti-MDA5 + DM compared with HCs, comprising 21 upregulated and 20 downregulated metabolites. The DEMs in PBMCs also mainly participated in the beta-alanine metabolism pathway. From these DEMs, DHEAS, citrate, dimethylglycine, histidine, PAGN and Melilotate were identified as candidate biomarkers in anti-MDA5 + DM. Clinically, DHEAS levels showed a negative correlation with the prevalence of rapidly progressive interstitial lung disease (RP-ILD), citrate exhibited a negative association with rash, while dimethylglycine displayed a positive association with mortality and RP-ILD. Further combined analysis showed that the expression of plasma and PBMC dehydroepiandrosterone sulfate (DHEAS) and citrate may serve as reliable diagnostic biomarkers. Finally, DHEAS and citrate exhibited concordant variation patterns in the validation cohort. Our study underscores the pivotal role of DHEAS and citrate as promising diagnostic biomarkers of IIM and anti-MDA5 + DM, respectively, providing novel insights into the pathogenic mechanism and potential therapeutic targets.

Currently, there are only a few effective treatments for anti-melanoma differentiation-associated gene 5 antibody (anti-MDA5) positive dermatomyositis (DM)-associated interstitial lung disease (ILD). The aim of this study was to evaluate the efficacy and safety of baricitinib in patients with MDA5 + DM-ILD. The study was a retrospective cohort design that evaluated patients with MDA5 + DM-ILD who had received or not received baricitinib. Clinical symptoms, laboratory data, and survival were compared in the two groups. Thirty-nine patients with MDA5 + DM-ILD who received baricitinib were included in the study. After baricitinib therapy, 31 patients (79.5%) had a clinical improvement that included Gottron’s sign (p < 0.001), heliotrope rash (p < 0.001), and dyspnea (p = 0.003). The median HRCT score decreased from 115 to 97.5 (p < 0.001), while the FVC improved significantly (76.44% vs. 90.73%, p < 0.001). In addition, serum ferritin levels (739.9 ng/ml vs. 56.3 ng/ml, p < 0.001) and lactate dehydrogenase (LDH) levels (313 U/L vs. 233 U/L, p = 0.003) decreased significantly. Notably, lymphocyte counts increased significantly, CD4 + T cells (354 cells/µl vs. 663 cells/µl, p < 0.001), and CD8 + T cells (180 cells/µl vs. 449 cells/µl, p < 0.001). Furthermore, the glucocorticoid dose reduced significantly from 40 mg daily to 10 mg daily (p < 0.001). Compared with the control group, the baricitinib group had a greater six-month survival (87.2% vs. 70%, p = 0.047). While first-line baricitinib showed a superior survival rate compared to conventional therapy (84.6% vs. 52.9%, p = 0.046). This study indicates that Baricitinib is a potential therapeutic for MDA5 + DM-ILD, reducing LDH and ferritin, ameliorating ILD progression, and improving survival, with first-line use may provide a significant survival advantage. However, larger prospective controlled studies are required to evaluate its efficacy. 1. This is the retrospective cohort study of baricitinib in the treatment of MDA5 + DM-ILD. 2. Baricitinib improve clinical symptoms, reduce LDH and serum ferritin levels, and reduce ILD progression in MDA5 + DM. 3. Baricitinib could improve MDA5 + DM patients’ survival, with first-line use may provide a significant survival advantage.
目前,对于抗黑色素瘤分化相关基因5抗体(anti-MDA5)阳性的皮肌炎(DM)相关间质性肺疾病(ILD),仅有少数有效的治疗方法。本研究的目的是评估巴西替尼对MDA5 + DM-ILD患者的疗效和安全性。该研究采用回顾性队列设计,评估了接受或未接受巴西替尼治疗的MDA5 + DM-ILD患者。比较两组患者的临床症状、实验室数据和生存率。39例接受巴西替尼治疗的MDA5 + DM-ILD患者纳入研究。baricitinib治疗后,31例(79.5%)患者的临床改善包括Gottron体征(p < 0.001)、heliotrope皮疹(p < 0.001)和呼吸困难(p = 0.003)。HRCT中位评分从115降至97.5 (p < 0.001), FVC显著改善(76.44% vs. 90.73%, p < 0.001)。血清铁蛋白水平(739.9 ng/ml vs. 56.3 ng/ml, p < 0.001)和乳酸脱氢酶(LDH)水平(313 U/L vs. 233 U/L, p = 0.003)显著降低。值得注意的是,淋巴细胞计数明显增加,CD4 + T细胞(354个细胞/µl比663个细胞/µl, p < 0.001)和CD8 + T细胞(180个细胞/µl比449个细胞/µl, p < 0.001)。此外,糖皮质激素剂量从每天40毫克显著减少到每天10毫克(p < 0.001)。与对照组相比,baricitinib组6个月生存率更高(87.2% vs 70%, p = 0.047)。与常规治疗相比,一线巴西替尼的生存率更高(84.6% vs. 52.9%, p = 0.046)。该研究表明Baricitinib是MDA5 + DM-ILD的潜在治疗药物,降低LDH和铁蛋白,改善ILD进展,提高生存率,一线使用可能提供显着的生存优势。然而,需要更大规模的前瞻性对照研究来评估其疗效。1. 这是baricitinib治疗MDA5 + DM-ILD的回顾性队列研究。2. Baricitinib改善临床症状,降低LDH和血清铁蛋白水平,并减少MDA5 + DM的ILD进展。3. Baricitinib可以改善MDA5 + DM患者的生存,一线使用可能提供显著的生存优势。

Patients with rheumatoid arthritis (RA) have an increased prevalence of comorbidities, which is associated with higher RA disease activity and worse disease outcomes. The aim of this analysis was to evaluate the impact of the comorbidity burden on the efficacy of the IL-6 inhibitor olokizumab (OKZ) and the tumour necrosis factor (TNF) inhibitor adalimumab (ADA) in the CREDO-2 randomized controlled clinical trial cohort of patients with active RA. A total of 1402 patients with RA were included in the analysis and divided into two groups on the basis of the modified Charlson Comorbidity Index (mCCI) at baseline: those having no comorbid conditions, NCC (mCCI = 1; RA only) vs. those having comorbid conditions, CC (mCCI ≥ 2; RA and ≥ 1 comorbidity). The key outcomes at Week (W) 24 were the proportions of patients with CDAI ≤ 10 and CDAI ≤ 2.8, other outcomes were ACR50 (W12, W24), proportions of patients with SDAI ≤ 3.3 (W24). All groups had similar proportions of approximately 25% of patients with mCCI ≥ 2. There was no significant difference in efficacy between the OKZ q4w or q2w-treated NCC and CC groups at 3 and 6 months of treatment. The same was observed for the placebo group. In contrast, comorbidities reduced CDAI ≤ 10 and ACR50 outcomes upon ADA treatment at 6 months. This post hoc analysis of the phase III CREDO-2 study suggests that the presence of at least one CCI comorbidity, including common disorders such as chronic pulmonary diseases and cardiovascular diseases, does not affect the OKZ treatment results in RA patients. In contrast, comorbidities reduce several efficacy outcomes upon ADA treatment at 6 months. The CCI was not associated with placebo group results and had no influence on safety outcomes.

Radiography is commonly used in clinical practice for detecting syndesmophytes in radiographic axial Spondyloarthritis (r-axSpA), while the ability of magnetic resonance imaging (MRI) to detect such bony structures is questionable due to its slicing technique. We aimed to assess the ability and performance for detection of syndesmophytes on MRI using different slice thicknesses and compare them with radiography in r-axSpA. MRI (T1-weighted (T1W) sequences) with slice thicknesses of 1–6 mm of the lower thoracic and lumbar spine were prospectively performed in patients with available radiographs. Each vertebral corner (VC) (anterior and posterior) from thoracic (Th11) to lumbar (L5) was assessed for presence/absence of syndesmophytes and/or fat lesions (FL, MRI only) by two experienced readers in independent MRI and radiography sessions and agreement was then reached in consensus. A total of 1.204 VCs were assessed from 43 r-axSpA patients. Syndesmophytes were recorded in 19.3% VCs on radiography and in 38.3%, 37.5%, 34.8%, 33.7%, 31.4%, 28.7% VCs on MRI slice thicknesses of 1–6 mm, respectively (all p ≤ 0.001 vs. radiography). Although more syndesmophytes were recorded on MRI than radiography, MRI also missed 21%-31.3% syndesmophytes detected in radiography. Agreement with radiography was found in 72.6%, 73.8%, 75.9%, 76%, 77.3% and 78.5% on MRI slice thicknesses of 1–6 mm, respectively. FL were detected in 38.2%-39.2% in slice thicknesses 1–6 mm. Occurrence of FL was associated with better agreement between MRI and radiography findings. The thinner the MRI slices, the more syndesmophytes were detected compared to radiography, but the best agreement with radiography was found in the thicker slices. The presence of fat lesions on MRI was associated with better agreement with radiography for syndesmophyte detection.
