Ding X, Liu J, Chen X, Zhang XH. Exploring the mechanism of luteolin improving immune and inflammatory responses in systemic sclerosis based on systems biology and cell experiments. Int Immunopharmacol 2024; 138:112587. [PMID: 38972211 DOI: 10.1016/j.intimp.2024.112587] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 06/13/2024] [Accepted: 06/26/2024] [Indexed: 07/09/2024]
Abstract
There is a growing trend of applying traditional Chinese medicine (TCM) to treat immune diseases. This study reveals the possible mechanism of luteolin, an active ingredient in the core prescription of TCM, in alleviating systemic sclerosis (SSc) inflammation. Bibliometrics was performed to retrieve the core keywords of SSc inflammation. The key inflammatory indicators in the serum samples of 50 SSc patients were detected by ELISA. Data mining was applied for correlation analysis, association rule analysis, and binary logistic regression analysis on the clinical indicators and medication of 50 SSc patients before and after treatment to determine the core prescription. Network pharmacology was used for identifying candidate genes and pathways; molecular docking was conducted to determine the core monomer components of the prescription, providing a basis for subsequent in vitro molecular mechanism research. The effect of luteolin on SSc-human dermal fibroblasts (HDF) viability and inflammatory factors was evaluated by means of ELISA, RT-PCR, and Western blot. The role of TNF in inflammation was explored by using a TNF overexpression vector, NF-κB inhibitor (PKM2), and SSc-HDF. The involvement of TNF/NF-κB pathway was validated by RT-PCR, Western blot, and immunofluorescence. TCM treatment partially corrected the inflammatory changes in SSc patients, indicating its anti-inflammatory effects in the body. Atractylodes, Yam, Astragalus root, Poria cocos, Pinellia ternata, Salvia miltiorrhiza, Safflower, Cassia twig, and Angelica were identified as the core prescriptions for improving inflammatory indicators. Luteolin was the main active ingredient in the prescription and showed a strong binding energy with TNF and NF-κB. Luteolin exerted anti-inflammatory effects in vitro by reducing inflammatory cytokines in SSc-HDF and inhibiting the activation of TNF/NF-κB. Mechanistically, luteolin inhibited the activation of the TNF/NF-κB pathway in SSc-HDF, as manifested by an increase in extranuclear p-P65 and TNF but a decrease in intranuclear p-P65. Interestingly, the addition of PKM2 augmented the therapeutic function of luteolin against inflammation in SSc-HDF. Our study showed the TCM alleviates the inflammatory response of SSc by inhibiting the activation of the TNF/NF-κB pathway and is an effective therapeutic agent for the treatment of SSc.

Abstract
Inflammatory rheumatic diseases (IRDs), encompassing a broad spectrum of chronic disorders, typically necessitate prolonged therapeutic intervention. Nevertheless, these diseases can sometimes manifest as severe emergencies requiring prompt and extensive medical intervention. Urgent intervention is essential for effectively recognizing and managing these situations, as they have the potential to be life-threatening and can result in severe morbidity and mortality. Emergencies in IRDs can occur with different frequencies and manifestations, including nervous system issues, severe infections, thrombosis-emboli, renal crises, gastrointestinal issues, and cardiovascular events. The fact that these events can occur across different IRDs underscores the necessity for heightened awareness and readiness among healthcare professionals. The pathophysiologic mechanisms that cause rheumatic emergencies are complex and involve multiple factors. These emergencies frequently arise due to the interplay between the inflammatory characteristics of rheumatic diseases and different systemic triggers. Early detection and treatment can have a substantial impact on an individual's prognosis in cases of severe and life-threatening disorders that require prompt recognition. Rapid decision-making and urgent care are required to effectively address rheumatic emergencies, as well as the implementation of a diagnostic flowchart. This article provides an overview of the emergencies linked to IRDs, classifying and assessing them individually. This article aims to enhance healthcare professionals' knowledge and awareness of critical situations by examining current recommendations and pathophysiological information. Implementing standardized diagnostic and treatment methods, providing patient education, and conducting continuing research into the underlying mechanisms are essential for enhancing the management of these critical situations and improving patient outcomes.

Abstract
INTRODUCTION Goh et al. proposed in 2008 a classificatory algorithm of limited or extensive SSc-ILD. The prevalence of both at the time of diagnosis of SSc-ILD is not known with exactitude. METHODS The review was undertaken by means of MEDLINE and SCOPUS from 2008 to 2023 and using the terms: "systemic", "scleroderma" or "interstitial lung disease" [MesH]. The Newcastle-Ottawa Scale was used for the qualifying assessment for observational studies and the Jadad scale for clinical trials. The inverse variance-weighted method was performed. RESULTS Twenty-seven studies were initially included in the systematic review and meta-analysis (SRMA). Of these, 17 studies had no overlapping data. They reported data from 2,149 patients, 1,369 (81.2%) were female. The mean age was 52.4 (SD 6.6) years. 45.2% of the patients had the diffuse subtype and 54.8% had the limited or sine scleroderma subtype. A total of 38.7% of the patients showed positive antitopoisomerase antibodies (ATA) and 14.2% positive anticentromere antibodies (ACA). The mean percentage of forced vital capacity (FVC) at baseline was 80.5% (SD 6.9) and of diffusing capacity of the lungs for carbon monoxide (DLco) was 59.1% (SD 9.6). Twelve studies presented SSc-ILD extension data adjusted for PFTs and were included in the meta-analysis. The 10 observational cohort studies were analyzed separately. The overall percentage of limited extension was estimated at 63.5% (95%CI 55.3-73; p < 0.001) using the random-effects model. Heterogeneity between studies (I2) was 9.8% (95%CI 0-68.2%) with the random-effects model. Extensive pulmonary involvement was estimated at 34.3% (95%CI 26-45.4; p < 0.001). Heterogeneity between studies (I2) was 0% (95%CI 0-61.6%) with the random-effects model. CONCLUSION The overall percentage of limited SSc-ILD at the time of diagnosis of SSc-ILD was estimated at 63.5% and extensive at 34.3%.

Abstract
Introduction Overlap syndrome (OS) is a group of systemic connective tissue diseases (CTDs) that meet the criteria of two or more CTDs. In this study, we evaluated clinical, laboratory, and capillaroscopic manifestations of patients with scleroderma OS (SSc-OS) and its subgroups and follow-up progression compared to patients with limited SSc (LcSSc). Material and methods In a 10-year cross-sectional study, we evaluated 135 adult patients (70 with SSc-OS and 65 with LcSSc) with the same skin score for their baseline and follow-up clinical, laboratory, high-resolution chest tomography (HRCT), echocardiography, and nailfold capillaroscopy data and compared them. Results Of the 135 patients, 70 had SSc-OS, including 45 (64.3%) cases of SSc-SS (Sjögren's syndrome), 11 (15.7%) of SSc-RA (rheumatoid arthritis), 9 (12.9%) of SSc-myositis and 5 (1.7%) of SSc-SLE (systemic lupus erythematosus), and 65 had LcSSc. Lung and heart involvement and pulmonary arterial hypertension (PAH) did not differ between the two groups (p > 0.05). Musculoskeletal involvement and non-specific pattern of capillaroscopy were higher (p = 0.035 and p = 0.001), and digital ulcer (DU) and scleroderma patterns of capillaroscopy were lower in the SSc-OS group (p = 0.000).No significant relationship was found between capillaroscopic patterns and organ involvement in the two groups (p-value > 0.05). In the follow-up (3.71 ±2.63 years), new DU and progression of lung involvement (p = 0.002) and the progression in capillaroscopic patterns was lower in SSc-OS (p = 0.000). In the follow-up, new DU was not seen in the SSc-OS, with lower progression of lung involvement, skin score, and capillary damage. Conclusions In SSc-OS patients, the most common subgroup was SSc-SS. Scleroderma OS was associated with lower major organ involvement and capillaroscopy progression than LcSSc. Major organ involvement in patients with SSc-OS was significantly lower than in LcSSc patients. In the follow-up, new DU was not seen in the SSc-OS with lower progression of lung involvement, skin score, and capillary damage.

Abstract
Objective The course of systemic sclerosis-associated interstitial lung disease (SSc-ILD) is highly variable and different from continuously progressive idiopathic pulmonary fibrosis (IPF). Most proposed definitions of progressive pulmonary fibrosis or SSc-ILD severity are based on the research data from patients with IPF and are not validated for patients with SSc-ILD. Our study aimed to gather the current evidence for severity, progression and outcomes of SSc-ILD.Methods A systematic literature review to search for definitions of severity, progression and outcomes recorded for SSc-ILD was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines in Medline, Embase, Web of Science and Cochrane Library up to 1 August 2023.Results A total of 9054 papers were reviewed and 342 were finally included. The most frequent tools used for the definition of SSc-ILD progression and severity were combined changes of carbon monoxide diffusing capacity (DLCO) and forced vital capacity (FVC), isolated FVC or DLCO changes, high-resolution CT (HRCT) extension and composite algorithms including pulmonary function test, clinical signs and HRCT data. Mortality was the most frequently reported long-term event, both from all causes or ILD related.Conclusions The studies presenting definitions of SSc-ILD 'progression', 'severity' and 'outcome' show a large heterogeneity. These results emphasise the need for developing a standardised, consensus definition of severe SSc-ILD, to link a disease specific definition of progression as a surrogate outcome for clinical trials and clinical practice.PROSPERO registration number CRD42022379254.Cite Now.

Abstract
OBJECTIVES Studies identifying nonspecific interstitial pneumonia (NSIP) as the predominant histopathology in systemic sclerosis-associated interstitial lung disease (SSc-ILD) have primarily utilised surgical lung biopsies in early disease. These case series may only reflect the histopathology of early disease and differ from the histopathology of advanced disease in those with respiratory failure. METHODS Patients receiving a lung transplant for a diagnosis of SSc at a single centre from 2000-2021 were included for retrospective analysis. All explanted lungs underwent histopathology review as part of routine care. RESULTS 127 patients with SSc received a native lung transplant during the study period. Usual interstitial pneumonia (UIP) was identified in 111 explants (87.4%), NSIP in 45 (35.4%) explants, organising pneumonia in 11 explants (8.7%), and lymphocytic bronchitis in 2 explants (1.6%). Areas of both UIP and NSIP were identified in 37 explants (29.1%), with only 9 explants (7.1%) showing neither UIP nor NSIP. Aspiration was identified on histology in 49 (38.6%) explants. Pathology results were available from a prior surgical lung biopsy for 19 patients, with 11 patients maintaining the same primary pathology on biopsy and explant (2 NSIP, 9 UIP) and 8 patients showing different pathology at the timepoints, all of whom had UIP on explant. Most patients (101, 79.5%) had evidence of pulmonary hypertension and vasculopathy on explant. CONCLUSIONS UIP is the predominant histopathology in patients with SSc receiving a lung transplant, with many patients concurrently having both NSIP and UIP or showing progression from NSIP to UIP over time before transplant.
