OBJECTIVES:To describe the prevalence of gastrointestinal (GI) symptoms in SSc and Very Early Diagnosis of SSc (VEDOSS), identify clinical and serological features associated with GI involvement and explore a cranio-caudal pattern of symptom distribution, using data from the Italian SPRING-SIR registry. METHODS:This cross-sectional analysis included patients fulfilling 2013 ACR/EULAR SSc or VEDOSS criteria. GI involvement was defined as symptoms in at least one GI tract segment and categorized as upper and lower. Associations between GI involvement and clinical variables were assessed using logistic and ordinal regression models, adjusting for demographics, disease characteristics and autoantibodies. RESULTS:Among 1917 SSc patients, 56% had GI symptoms, associated with longer disease duration, dcSSc, interstitial lung disease (ILD), digital ulcers (DU), telangiectasias and tobacco exposure. Extensive GI involvement correlated with more severe disease. Ordinal regression identified female sex, dcSSc, ILD, DU, telangiectasias, tobacco exposure and anti-centromere antibodies as variables significantly associated with more extensive GI involvement. Disease duration did not show a significant association with GI symptom extent. Among 211 VEDOSS patients, 41.2% reported GI symptoms (mostly oesophageal), significantly associated with puffy fingers and dyspnoea. Among VEDOSS, puffy fingers and anti-centromere antibodies were independent predictors of presence of oesophageal symptoms. CONCLUSION:GI involvement in SSc is linked to more severe disease and longer disease duration. Disease duration resulted linked to the presence of GI symptoms rather than extent of GI involvement. Puffy fingers and anti-centromere antibodies may associate with presence of early oesophageal symptoms in VEDOSS.

OBJECTIVES:To assess the relationship between disease duration and the prevalence/distribution of nailfold videocapillaroscopy (NVC) patterns, named according to the current classification as 'early', 'active' and 'late', in a large cohort of systemic sclerosis (SSc) patients. METHODS:A cross-sectional analysis was conducted on 1689 patients undergoing standardized NVC. Clinical-serological data and treatments were collected. Statistical comparisons and multivariable logistic regression models were applied, including analyses based on disease duration. RESULTS:The prevalence of NVC patterns was as follows: 'early' 21.6%, 'active' 47.4%, 'late' 25.7% and normal/non-specific 5.3%. The distribution by disease duration showed that the three main patterns were always present. While the 'early' and 'active' progressively decreased (from 30.3% and 51.9% in patients with ≤5 yrs, to 14.6% and 43.5% in those >10 yrs, P < 0.01), the 'late' pattern increased from 13.2% (≤5 yrs) to 36.0% (>10 yrs) (P < 0.001) and was associated with internal organ involvement, anti-topoisomerase antibodies and more therapies (P < 0.01). Conversely, the 'early' and 'active' patterns were associated with the limited-cutaneous subset (P < 0.01) and anti-centromere antibodies (P < 0.001). Multivariable analysis confirmed a strong association between the 'late' pattern and skin/peripheral vascular involvement. Notably, the presence of the 'late' pattern in patients with ≤2 yrs (10.9%) was significantly associated with scleroderma renal crisis (P = 0.012). CONCLUSION:SSc-NVC patterns are not strictly time-dependent and can be observed at any stage of the disease, suggesting that microvascular damage progression is heterogeneous across different disease periods. Therefore, a revised classification of NVC changes considering both disease duration and NVC severity could improve its prognostic accuracy.

OBJECTIVE:Mycophenolate mofetil (MMF) use in limited cutaneous systemic sclerosis (lcSSc) is relatively uncommon because of the lower fibrotic burden and the predominance of vascular complications. In vitro observations and clinical data from transplanted patients suggest a protective effect of MMF on endothelial function. Our aim was to evaluate the reasons for prescribing MMF treatment in patients with lcSSc and its impact on the need for escalation of vascular complication-related treatments during follow-up. METHODS:Patients with lcSSc enrolled in the Italian Systemic Sclerosis Progression Investigation registry were retrospectively evaluated. All patients treated with MMF were matched to patients not treated with MMF, which was based on a roll-entry time-dependent propensity score built on demographics, clinical features, and baseline treatment. The escalation of vasoactive or vasodilator treatment up to 60 months was defined as the introduction of iloprost, endothelin receptor antagonists, or phosphodiesterase-5 inhibitors on top of the ongoing treatment, because of uncontrolled or newly diagnosed vascular complications. A hazards Cox model was also adopted to quantify the association of MMF treatment with treatment escalation. RESULTS:A total of 1,435 patients with lcSSc were evaluated, of whom 152 were prescribed MMF (17.1% male; mean age at lcSSc onset 48.7 ± 13.9 years, 54.6% anti-Scl70 positive). The prescription of MMF was more common in men and in anti-Scl70 positive, anticentromere negative patients with interstitial lung disease, myositis, and without a history of digital ulcers. After matching 107 patients with MMF-untreated controls, the overall incidence of vasoactive/vasodilator treatment escalation events related to digital ulcers over a median follow-up of 40.5 months (interquartile range 23.3-60.0) was 0.3 per 100 patient-years in the MMF-treated group and 5.4 per 100 patient-years in the matched control group, with a significant difference in treatment escalation-free survival between the two groups (hazard ratio 0.05, 95% confidence interval 0.01-0.38; P value = 0.004). CONCLUSION:In patients with lcSSc, the introduction of MMF has reduced the need for escalation of vasoactive or vasodilator treatment, suggesting that it may also help to prevent vascular complications, which frequently affect patients with lcSSc.

Background:The sequence and temporal relationship between Raynaud's phenomenon (RP) and the first non-Raynaud's sign/symptom (NRP) in systemic sclerosis (SSc) have been partially investigated. Objectives:To evaluate whether the mode and ages of clinical onset are associated with disease endotype and survival in SSc. Design:We included SSc patients from the Systemic sclerosis Progression INvestiGation registry of the Italian Society of Rheumatology (SPRING-SIR) registry in a cohort study, with post hoc cross-sectional and longitudinal analysis. Methods:Patients were grouped based on age-RP and age-NRP quartiles. Additionally, categories were defined based on mode of onset: RP group-RP onset at least 1 year before NRP; Simultaneous group-RP onset within the same year of NRP; NRP group-RP onset after at least 1 year after NRP. Comparisons were made using Chi-square and ANOVA tests. Logistic, linear, and multinomial regression models were applied to assess associations, while Kaplan-Meier curves and Cox regression were used to assess mortality. Results:A total of 1748 patients were eligible: 682 (39.0%) in the RP group, 1026 (58.8%) in the simultaneous group, and 39 (2.2%) in the NRP group. A higher prevalence of anti-centromere antibodies was found In the RP group, while the simultaneous group had more diffuse cutaneous SSc (dcSSc), anti-topoisomerase-I antibodies, and higher Rodnan's skin score (mRSS). The NRP group presented higher prevalence of pulmonary arterial hypertension. On logistic regression, the simultaneous group was associated with a higher prevalence of dcSSc compared to the RP group (odds ratio, 1.491, 95% confidence interval (CI): 1.032-2.154). Younger age at RP onset was associated with lower systolic pulmonary artery pressure and mRSS. In 943 patients with available follow-up (median 24 months), the simultaneous group had higher mortality compared to the RP group (hazard ratio, 1.975, 95% CI: 1.002-3.893). Conclusion:The timing of RP and NRP onset may help define SSc endotype and survival. Patients with simultaneous RP-NRP onset have more severe disease features and higher mortality risk, emphasizing the relevance of onset timing in disease stratification.

Background: Rheumatoid arthritis-associated interstitial lung disease (RA-ILD) is a major extra-articular manifestation of rheumatoid arthritis (RA), contributing substantially to morbidity, mortality, and patient burden. Its diagnosis and management require integration of rheumatologic, pulmonary, and radiologic perspectives. Multidisciplinary approaches may provide a practical framework for implementing personalized medicine by integrating clinical and immunologic heterogeneity into individualized care strategies, although real-world data remain limited. Objectives: To synthesize primary studies published between 2015 and 2025 examining diagnostic, organizational, educational, and clinical aspects of RA-ILD within a multidisciplinary care framework. Methods: A narrative review of original research was conducted using PubMed and major publisher platforms from 1 January 2015 to 30 November 2025. Search terms included “rheumatoid arthritis,” “interstitial lung disease,” “RA-ILD,” “connective-tissue disease ILD,” “multidisciplinary,” “diagnosis,” “management,” and “patient experience.” Reviews and consensus statements were excluded. Results: Fifteen articles underwent full-text review, and five primary studies met all inclusion criteria and were incorporated into the final synthesis. RA-ILD emerged as a condition requiring coordinated interpretation of imaging, pulmonary physiology, and rheumatologic features. Multidisciplinary evaluation may improve diagnostic accuracy, reduce unclassifiable ILD, and support differentiation of autoimmune-related from idiopathic disease. A global assessment of ILD multidisciplinary team practices revealed substantial variability in structures and processes. Patient-reported data demonstrated significant emotional distress and a need for clearer communication and coordinated educational support. Conclusions: Effective RA-ILD management depends on collaborative assessment across specialties. Multidisciplinary care may support diagnostic precision and provide a practical framework for personalized medicine by integrating clinical, radiologic, and immunologic heterogeneity into tailored diagnostic and therapeutic strategies.

Background: The recent availability of infliximab subcutaneous biosimilar in Europe represents a significant advancement in therapeutic delivery. Real-world data regarding the new formulation are still limited. Objectives: To describe subcutaneous infliximab (scIFX) use in immune-mediated inflammatory diseases (IMIDs), evaluating clinical effectiveness, treatment persistence, and factors influencing drug retention rates (DRRs). Methods: Adult patients with IMIDs treated with scIFX either de novo or after switching from intravenous infliximab (ivIFX) were included. Disease activity was assessed using standard indices, and persistence was evaluated through 18-month DRRs. Results: In total, 201 patients were included (66.7% women): 68 with psoriatic arthritis (33.8%), 66 axial spondyloarthritis (32.8%), 18 rheumatoid arthritis (9.0%), 18 Behçet’s disease (9.0%), 16 juvenile idiopathic arthritis (8.0%), 10 Takayasu arteritis (5.0%), and 5 other IMIDs (2.5%). Median treatment duration was 14 months (interquartile range 13.0). Ninety-five patients (47.3%) switched from ivIFX, while 106 initiated scIFX de novo, of whom 74 (78.3%) received induction. Median disease activity grades improved from baseline through 24 months ( p < 0.001). Fifty-five subjects (27.4%) discontinued scIFX. DRRs were 88.5%, 76.9%, and 68.3% at 6, 12, and 18 months, respectively. DRRs were higher in switchers versus de novo initiators ( p = 0.038), also controlling for baseline activity and loading protocol (hazard ratio = 0.25 [95% confidence interval: 0.075–0.848], p = 0.026). De novo patients without induction had lower DRRs ( p = 0.033) than those receiving induction, whereas line of biologic therapy ( p = 0.066) and body mass index (BMI; p = 0.445) had no effect on scIFX DRRs. Adverse events occurred in 21 patients (10.4%). Conclusion: ScIFX appears effective across IMIDs, with sustained retention over time. Prior ivIFX exposure and use of induction protocols are associated with improved persistence, while treatment line and BMI appear not to influence outcomes.

Background:Microvascular alterations can be detected with nailfold videocapillaroscopy, useful for systemic sclerosis (SSc) diagnosis upon identification of the "scleroderma pattern" (NVC-SP). However, this pattern is missing in a subset of SSc patients. Methods:This retrospective analysis on the multicenter Italian SPRING cohort of SSc patients assessed the prevalence and characteristics of patients without NVC-SP. Associations with demographic and clinical features were evaluated using logistic regression (cross-sectional) and mixed-effects models (longitudinal). Results:Out of 1689 SSc patients with available NVC information, 90 (5.3%) did not have the NVC-SP. These patients were older at SSc onset (53 vs. 49 years) and more frequently sine scleroderma (31% vs 12%, p < 0.001). The overall burden of vascular complications was milder in this subset, with a lower prevalence of pitting scars (33% vs 48%), telangiectasias (52% vs 74%), and calcinosis (3.4% vs 12%). During the follow-up, mRSS remained lower (60-month mean 4 vs 7, p = 0.002), as well as the estimated probability of vascular complications. Moreover, despite comparable values at baseline, DLCO remained significantly higher in patients without NVC-SP at the following time points (12, 24, and 60 months, p < 0.05). The presence of "late" NVC-SP was independently associated with ILD (OR 1.83, 95% CI 1.05-3.18). Conclusions:The absence of NVC-SP in 5.3% of SPRING SSc patients may identify a subset characterized by milder disease, with a lower burden of vascular and organ complications. Conversely, lung involvement was more frequently observed in patients with more severe NVC microangiopathy.

Background Antitopoisomerase I (ATA), anticentromere (ACA) and anti-RNA polymerase III (RNAP3) antibodies are included in the 2013 American College of Rheumatology/European Alliance of Associations for Rheumatology classification criteria for systemic sclerosis (SSc). A subset of patients with SSc satisfy criteria but may lack these specific autoantibodies, being classified as ‘triple-negative’.Methods We conducted a retrospective evaluation of triple-negative patients with SSc prevalence and clinical features among the multicentric Systemic sclerosis Progression INvestiGation registry.Results Out of 1480 patients with SSc, 295 (19.9%) were triple-negative, while 1185 (81.1%) had SSc-specific antibodies: ACA (54.3%), ATA (43.6%) and RNAP3 (2.1%). The triple-negative group showed a higher prevalence of myopathy (16.7% vs 10.1%, p=0.003), suggested by higher creatine phosphokinase (CPK) levels (126.2 vs 92.5 U/mL, p=0.002), more frequent CPK increase over 2–3 times (2.4% vs 0.2%, p=0.028). Triple-negative patients also exhibited fewer vascular complications, including digital ulcers (17.3% vs 22.8%, p=0.04) and calcinosis (8.2% vs 12.8%, p=0.027), and a higher prevalence of interstitial lung disease (p<0.001). Consistently, lower diffusing capacity for carbon monoxide (66.4% vs 70.98%, p=0.004) and forced vital capacity (97.01% vs 102.92%, p<0.001) were found in the triple-negative group. Triple-negative patients more frequently received corticosteroids (79.3% vs 67.9%, p=0.003), cyclophosphamide (43.4% vs 26%, p<0.001) and azathioprine (38.5% vs 22.3%, p=0.002), while less frequently received prostanoids (71.6% vs 85.9%, p<0.001), calcium channel blockers (80.1% vs 87.7%, p=0.005) and phosphodiesterase-5 inhibitors (4% vs 20%, p<0.001).Conclusions A higher prevalence of myopathy and interstitial lung disease and a reduced vascular burden were found in the triple-negative patients, suggesting that the non-specific and non-routinely tested autoantibodies may identify an SSc endotype resembling sclero-myositis.

Systemic sclerosis (SSc) is a rare, chronic connective tissue disease characterised by a complex and not yet fully understood pathophysiology, leading to a wide spectrum of clinical manifestations. Despite important advances over recent years in elucidating disease mechanisms, improving early recognition, and expanding therapeutic options, SSc continues to represent a major clinical challenge due to its heterogeneity and unpredictable course.Ongoing research efforts are essential to better define disease subsets, identify prognostic markers, and refine treatment strategies. In this context, this annual review provides a critical overview of the most relevant studies published in 2025, with a focus on advances in pathogenesis, organ involvement, therapeutic approaches, and patient outcomes in systemic sclerosis.

INTRODUCTION:Primary heart involvement (pHI) is an overlooked and poorly characterised complication of systemic sclerosis (SSc), associated with the risk of heart failure, arrhythmia and death. Despite consensus definition by the World Scleroderma Foundation/Heart Failure Association (WSF/HFA), diagnostic criteria and risk factors remain poorly elucidated. METHODS:Out of 1922 patients in the Italian national SPRING registry, we excluded those with potentially confounding conditions according to WSF/HFA, and those with incomplete ECG or echocardiographic assessment, resulting in 600 subjects with clearly defined parameters to intercept SSc-pHI. Cross-sectional and longitudinal analyses were performed to identify factors associated with pHI. RESULTS:ECG and/or echocardiographic signs of SSc-pHI were identified in 25% of patients at enrollment and were associated with older age (OR 1.04; 95% CI 1.02-1.06), diffuse cutaneous SSc (OR 1.85; 95% CI 1.05-3.26) and intestinal symptoms (OR 1.79; 95% CI 1.03-3.08). Diastolic dysfunction (62%) and conduction disturbances (34%) were the most frequent phenotypes, while diffuse hypokinesia with reduced ejection fraction was the least common (3%). During follow-up, new-onset signs of pHI were observed in an additional 25% of patients, particularly in those with skeletal muscle involvement (HR 2.83; 95% CI 1.01-7.73). CONCLUSIONS:pHI is a severe complication potentially affecting one-quarter of patients with SSc. Early detection is crucial, particularly in those with diffuse skin fibrosis, muscular involvement and intestinal manifestations.

OBJECTIVES:MMF is a mainstay for the treatment of SSc. The occurrence and implications of MMF-related adverse events (AEs) on drug retention rates in real life remain poorly defined. We aimed to determine the MMF retention rate and to investigate the causes and patterns of discontinuation, AEs and treatment options used after discontinuation. METHODS:SSc patients who started MMF treatment underwent a retrospective longitudinal assessment for up to 5 years. We documented the incidence, predictors and impacts of MMF treatment on gastrointestinal intolerance, infections, laboratory abnormalities and cancer. Rescue strategies implemented after MMF discontinuation were recorded. RESULTS:The 5-year MMF retention rate of 554 patients stood at 70.7%, and 19.6% of them stopped MMF due to AEs. One out of every four patients experienced a dose reduction or discontinuation of MMF due to AEs, with gastrointestinal intolerance being the predominant cause. The 5-year cumulative incidence rates for gastrointestinal intolerance, cancer, severe infections and laboratory toxicity leading to MMF discontinuation were 6.4%, 4.1%, 3.1% and 2.1%, respectively. Lower respiratory tract was the most affected, with bacteria being the predominant causative agent. Intestinal and pulmonary circulation involvement were tied to elevated AE rates and MMF discontinuation. The most common approaches post-MMF cessation were 'watch and wait' and switch to rituximab. CONCLUSIONS:: MMF use in SSc appears to be limited by the occurrence of AEs, both in terms of persistence and dosing of the drug. Rescue options after MMF discontinuation are limited and many patients remain without immunosuppressant.

ObjectiveBosentan (BOS) is approved for treating pulmonary arterial hypertension (PAH) and preventing digital ulcers (DU) in systemic sclerosis (SSc). Our study aimed to evaluate whether BOS prescribed for DU could reduce the incidence of PAH in a large SSc cohort from the Systemic Sclerosis Progression Investigation (SPRING) registry.MethodsPatients with SSc from the SPRING registry, meeting 2013 American College of Rheumatology/European Alliance of Associations for Rheumatology classification criteria with data on PAH onset, DU status, BOS exposure, and at least 1 year of follow-up between 2015 and 2020, and having no known PAH at baseline, were included. PAH was diagnosed with right heart catheterization during the follow-up, and its incidence rate (IR) was calculated. Kaplan-Meier curves were determined, and multivariate regression identified PAH risk factors.ResultsAmong 727 eligible patients with SSc, followed for a median of 2.0 years, 54 (7.4%) developed PAH (IR 3.71 per 100 patient-years [PYs]). Patients with DU who were never exposed to BOS had a higher incidence of PAH (IR 4.90 per 100 PYs) compared to those exposed to BOS, whose rates matched those without DU and who were never exposed to BOS. Risk factors independently associated with PAH development included DU (hazard ratio [HR] 1.86), age (HR 1.05), modified Rodnan skin score > 4 (HR 2.07), interstitial lung disease (HR 2.29), and acetylsalicylic acid treatment (HR 1.78).ConclusionIn our cohort, the presence of DU was confirmed as a leading risk factor for PAH development, and BOS use for DU prevention may reduce this risk. Only patients with DU who were not using BOS had an increased PAH incidence.

OBJECTIVE:Some concerns remain about the safety of nintedanib in patients with rheumatoid arthritis-related interstitial lung disease (RA-ILD), such as in the presence of comorbidities or in combination with biologic, targeted synthetic, and/or conventional synthetic disease-modifying antirheumatic drugs (DMARDs). In this multicenter study, we retrospectively evaluated the safety of nintedanib in a real-world population of patients with RA-ILD from the Italian Group for the Study of Early Arthritis (GISEA) registry and the possible role of comorbidities and DMARDs on drug safety and withdrawal. Our secondary aim was to investigate the causes of nintedanib discontinuation. METHODS:Sixty-five patients treated with nintedanib in accordance with the current therapeutic indications were enrolled in the study. Nintedanib was prescribed in combination with DMARDs and/or steroids in 62 patients (95.4%). RESULTS:The 12-month retention rate of nintedanib was 76.7% and the drug was effective in about 80% of patients with ≥ 6 months of follow-up. Adverse events (AEs) were recorded in 36 subjects (55.3%), and these were mainly gastroenteric. Thirty-one subjects required a reduction of the nintedanib dose; among them, a transient or permanent reduction of the daily dose of nintedanib allowed the continuation of the treatment in 22, whereas 15 (23.1%) withdrew from the drug. All reductions and discontinuations were owing to treatment-related AEs. Comorbidities were significantly associated with side effects in multivariate analysis, whereas AEs due to nintedanib were the main cause of discontinuation. CONCLUSION:Combination therapy with DMARDs did not reduce the safety and effectiveness of nintedanib, and AEs were the main cause of drug withdrawal or dose reduction, mainly owing to comorbidities.

OBJECTIVES:We aimed to assess lung involvement in patients with psoriatic arthritis (PsA), hypothesising that lung diseases (LDs) represent a distinct comorbidity of PsA and that the association between these two conditions is not merely coincidental. METHODS:Cross-sectional study of 322 patients with a diagnosis of PsA from three Italian centres. Each patient underwent a chest high-resolution CT prior to the start of a biological DMARDs. After pneumologists' evaluation, patients were divided into three groups [chronic obstructive pulmonary disease (COPD), interstitial lung disease (ILD), and non-LD]. Univariate and multivariate statistical analysis were performed to analyse demographic and clinical characteristics of the total cohort and to compare disease characteristics between PsA patients with and without lung involvement. RESULTS:COPD was diagnosed in 39 patients (12.1%) and ILD in 27 patients (8.4%). The inflammatory burden [DAPSA>14 (OR 4.3, p.adj=0.03), swollen joint count (SJC)>3 (OR 3.2, p.adj=0.02), PASI>10 (OR 3.6, p.adj=0.008), BMI ≥30 (OR 3, p.adj=0.04)] emerged as the most important risk factor for COPD development in PsA patients. This association was weaker in patients with ILD and PsA, since just SJC emerged as a risk factor for ILD development [SJC>3 (OR 3, p.adj=0.04)]. Old age (≥65 years) increased the risk of COPD by up to 9.6 times (p.adj=0.004) and ILD by up to 7.6 times (p.adj=0.04). CONCLUSIONS:Our data support the hypothesis of a correlation between PsA and LDs highlighting that non-traditional risk factors may contribute to the development of LDs in PsA patients, especially in cases of uncontrolled, active articular disease.

Mesenchymal stem cell (MSC) transplantation has emerged as a potential therapeutic strategy for systemic sclerosis (SSc), a rare autoimmune disease characterized by inflammation, fibrosis, and vasculopathy. Recent evidence suggests that the therapeutic benefits of MSCs do not depend directly on their ability to proliferate but rather on their capacity to release extracellular nanovesicles known as exosomes (MSC-Exos). MSC-Exos are rich in bioactive molecules such as microRNAs, which can modulate gene expression and trigger significant biological responses, playing a central role in modulating immune responses, inhibiting fibrotic pathways and promoting tissue repair and angiogenesis. Preclinical studies have demonstrated that MSC-Exos can attenuate fibrosis, modulate macrophage polarization, suppress autoreactive lymphocyte activity, and even reverse pulmonary arterial hypertension in animal models of SSc. Compared to cell-based therapies, MSC-Exos offer several advantages, including lower immunogenicity and better safety profile. This review provides an overview of the immunomodulatory, antifibrotic, and angiogenic properties of MSC-Exos and explores their potential as novel cell-free therapy for SSc.

Kikuchi-Fujimoto disease (KFD) is a rare and benign lymphadenopathy of unknown etiology. Usually, it is an isolated and self-limiting condition requiring no specific therapy; however, in some cases, it may be associated with an autoimmune disease. Here, we report three cases of KFD developing an associated autoimmune connective disorder: the first case presented with Sjögren's syndrome, and the other two had a diagnosis of systemic lupus erythematosus.
