Background: Progressive pulmonary fibrosis (PPF) has been associated with a worse prognosis, even when interstitial lung disease (ILD) is related to rheumatic diseases. Since many differences are detectable among rheumatic diseases in prevalence and features of ILD, we aimed to investigate features of PPF in different rheumatic diseases, namely rheumatoid arthritis (RA) and primary Sjogren's syndrome (pSS). Methods: In an Italian multicentre cross-sectional study, consecutive pSS or RA patients with a diagnosis of ILD from at least two years were enrolled. For each patient, demographic, clinical, and serological data, other than chest high-resolution computed tomography and lung function tests, were recorded at the enrolment and after 2 years. Results : Among 232 patients, namely 156 RA-ILD and 76 pSS-ILD, a PPF was recorded in 38.8% of cases, without differences between the two diseases. Analysing patients with a PPF, usual interstitial pneumonia was significantly more frequent in RA than pSS (71.4% and 44.4%, respectively; p = 0.019), while ILD preceded the diagnosis of the rheumatic disease in 29.1% of RA and 89.5% of pSS ( p < 0.001). Finally, RA patients were significantly younger than pSS at the diagnosis of the rheumatic disease ( p < 0.001). Conclusions: In conclusion, although there is a similar prevalence of PPF in RA-ILD and pSS-ILD, we demonstrated for the first time that the two conditions differ in terms of radiological patterns and demographic and clinical features, suggesting that specific factors related to such diseases might influence the lung involvement over time. Prospective studies could investigate if these specificities could induce different responses to the treatment.

Background: The INBUILD study demonstrated the efficacy of nintedanib in the treatment of progressive fibrosing interstitial lung disease different to idiopathic pulmonary fibrosis, including rheumatoid arthritis (RA)-related ILD. Nevertheless, the prevalence of RA-ILD patients that may potentially benefit from nintedanib remains unknown., Objectives and Methods: The aim of the present multicentre study was to investigate the prevalence and possible associated factors of fibrosing progressive patterns in a cross-sectional cohort of RA-ILD patients., Results: One hundred and thirty-four RA-ILD patients with a diagnosis of RA-ILD, who were confirmed at high-resolution computed tomography and with a follow-up of at least 24 months, were enrolled. The patients were defined as having a progressive fibrosing ILD in case of a relative decline in forced vital capacity > 10% predicted and/or an increased extent of fibrotic changes on chest imaging in a 24-month period. Respiratory symptoms were excluded to reduce possible bias due to the retrospective interpretation of cough and dyspnea. According to radiologic features, ILD was classified as usual interstitial pneumonia (UIP) in 50.7% of patients, nonspecific interstitial pneumonia in 19.4%, and other patterns in 29.8%. Globally, a fibrosing progressive pattern was recorded in 36.6% of patients (48.5% of patients with a fibrosing pattern) with a significant association to the UIP pattern., Conclusion: We observed that more than a third of RA-ILD patients showed a fibrosing progressive pattern and might benefit from antifibrotic treatment. This study shows some limitations, such as the retrospective design. The exclusion of respiratory symptoms' evaluation might underestimate the prevalence of progressive lung disease but increases the value of results.

Introduction: Interstitial lung diseases (ILDs) are diseases characterised by excessive deposition of collagen matrices in the pulmonary interstitium. Some of them are considered idiopathic (idiopathic pulmonary fibrosis - IPF), others are related to known pathologies such as connective tissue diseases (CTDs-ILD). Patient affected by ILD and features referable to CTD, not satisfying CTD criteria, are called Interstitial pneumonia with autoimmune features (IPAF) patients., Objective: The aim of this report was to investigate clinical and serologic features of a monocentric cohort of patients with IPAF. Another objective was to describe the autoantibody profile, clinical features, High Resolution Computerised Tomography (HRCT) and Nailfold Video Capillaroscopy (NVC) patterns., Methods: 36 IPAF patients were consecutively enrolled. Clinical, serological, and morphological features were collected., Results: 36 consecutive IPAF patients were enrolled from January 2021 to January 2022. Raynaud's phenomenon was the most frequent symptom identified. We also described other signs and symptoms not included in IPAF criteria. 36,1% of patients demonstrated a Usual Interstitial Pneumonia (UIP) pattern by HRCT. Pulmonary arterial pressure estimation (PAPs) resulted elevated (≥ 25 mmHg) in 6 patients. Antinuclear antibodies (ANA) ≥ 1/80 was the most frequent autoantibody, followed by anti-Ro, in patients with UIP pattern and Non-Specific Interstitial Pneumonia (NSIP) pattern at HRCT. NVC highlighted non-specific microangiopathy as the most common pattern especially in UIP patients., Conclusions: This paper may contribute to stimulate the interest in better characterisation of clinical, serologic, and instrumental features for IPAF patients by redefining IPAF classification criteria in order to treat them as best as possible., Competing Interests: The authors declare no conflict of interest., (© 2023 The Mediterranean Journal of Rheumatology (MJR).)

Objectives: To evaluate the rate of progression towards specific autoimmune diseases (SADs) of a prospective, multi-centre cohort of patients classifiable as interstitial pneumonia with autoimmune features (IPAF)., Methods: IPAF patients were enrolled based on specific research criteria, and jointly followed by rheumatologists and pulmonologists for at least one year with clinical check-ups, serological exams including autoimmunity, capillaroscopy and high-resolution computed tomography (HRCT). Diagnostic assessment was repeated at least once a year, or earlier when deemed useful., Results: We enrolled 191 IPAF patients through 95 different combinations of IPAF criteria. Of these, 24.1% progressed towards SAD, mainly in connective tissue diseases but also in microscopic polyangiitis. The IPAF patients who progressed were younger than stable IPAF patients (63±10 years vs. 68±9 years, p=0.002) and had a longer follow-up (36.9±18.7 vs. 29.3±15.7 months, p=0.007), but similar severity. No parameters were associated with overall progression, but some parameters were associated with the development of specific diagnoses: Sjögren's syndrome with positivity for SSA (p=0.007, χ2 7.4); idiopathic inflammatory myopathy with mechanic's hands (p=<0.0001, χ2 12.6), organizing pneumonia pattern (p=0.01, χ2 6.1), positivity for anti-Pm/scl (p=0.04 χ2 4.1) and anti-MDA5 (p=0.04, χ2 4.2); systemic sclerosis with palmar telangiectasias (p=<0.0001 2 18.3), positivity for anti-Scl70 (p=<0.0001 χ2 12.5) and anti-PM/Scl (p=0.001 χ2 10.1)., Conclusions: IPAF patients had a rate of progression towards SAD similar to that reported in previous studies on undifferentiated connective tissue diseases, thus including some patients in which lung involvement could represent the first or even the sole clinical manifestation of a SAD.

Purpose of the present paper is to point out the design, development and deployment of the AutoInflammatory Disease Alliance (AIDA) International Registry dedicated to pediatric and adult patients with Behçet's disease (BD). The Registry is a clinical physician-driven non-population- and electronic-based instrument implemented for the retrospective and prospective collection of real-life data about demographics, clinical, therapeutic, laboratory, instrumental and socioeconomic information from BD patients; the Registry is based on the Research Electronic Data Capture (REDCap) tool, which is thought to collect standardised information for clinical real-life research, and has been realised to change over time according to future scientific acquisitions and potentially communicate with other existing and future Registries dedicated to BD. Starting from January 31st, 2021, to February 7th, 2022, 110 centres from 23 countries in 4 continents have been involved. Fifty-four of these have already obtained the approval from their local Ethics Committees. Currently, the platform counts 290 users (111 Principal Investigators, 175 Site Investigators, 2 Lead Investigators, and 2 data managers). The Registry collects baseline and follow-up data using 5993 fields organised into 16 instruments, including patient's demographics, history, clinical manifestations and symptoms, trigger/risk factors, therapies and healthcare access. The development of the AIDA International Registry for BD patients will facilitate the collection of standardised data leading to real-world evidence, enabling international multicentre collaborative research through data sharing, international consultation, dissemination of knowledge, inclusion of patients and families, and ultimately optimisation of scientific efforts and implementation of standardised care.Trial registration NCT05200715 in 21/01/2022., (© 2022.

Introduction: The aim of this paper is to point out the design, development and deployment of the AutoInflammatory Disease Alliance (AIDA) International Registry for paediatric and adult patients with non-infectious uveitis (NIU)., Methods: This is a physician-driven, population- and electronic-based registry implemented for both retrospective and prospective collection of real-world demographics, clinical, laboratory, instrumental and socioeconomic data of patients with uveitis and other non-infectious inflammatory ocular diseases recruited through the AIDA Network. Data recruitment, based on the Research Electronic Data Capture (REDCap) tool, is thought to collect standardised information for real-life research and has been developed to change over time according to future scientific acquisitions and potentially communicate with other similar instruments. Security, data quality and data governance are cornerstones of this platform., Results: Ninety-five centres have been involved from 19 countries and four continents from 24 March to 16 November 2021. Forty-eight out of 95 have already obtained the approval from their local ethics committees. At present, the platform counts 259 users (95 principal investigators, 160 site investigators, 2 lead investigators, and 2 data managers). The AIDA Registry collects baseline and follow-up data using 3943 fields organised into 13 instruments, including patient's demographics, history, symptoms, trigger/risk factors, therapies and healthcare utilization for patients with NIU., Conclusions: The development of the AIDA Registry for patients with NIU will facilitate the collection of standardised data leading to real-world evidence and enabling international multicentre collaborative research through inclusion of patients and their families worldwide., (© 2022.

Objective: To report baseline data of SLE patients enrolled in the Lupus Italian Registry (LIRE)., Methods: Patients affected by SLE aged ≥ 16 years were consecutively recruited in a multicenter prospective study comparing two cohorts: patients starting biologic immunosuppressants (BC) and patients starting non-biologic immunosuppresants (NBC)., Results: 308 patients were enrolled, 179 in NBC and 129 in BC. Mean age at disease onset and at diagnosis was significantly higher in NBC (p = 0.023, p = 0.045, respectively). Disease duration was longer in BC (p = 0.022). Patients in BC presented arthritis more frequently (p = 0.024), those in NBC nephropathy (p = 0.03). Quality of life was worse in BC (p = 0.031). Anti-dsDNA, low C3, were significantly more frequent in BC (p < 0.001, p = 0.009, respectively). Mycophenolate, methotrexate and azathioprine were the drugs more frequently prescribed in NBC, Belimumab and Rituximab in BC., Conclusion: The predominant organ involvement was different in the two cohorts: kidney involvement predominated in NBC, joint involvement in BC. Despite the younger age at disease onset, patients of the BC had a longer disease duration and more frequently had taken a cumulative prednisone dosage greater than 10 g. Even the pattern of clinical manifestations inducing to prescribe biological rather than conventional immunosuppressants was quite different.Keywords: Autoantibody(ies), autoimmune disease, belimumab, cohort studies, glucocorticoids, immunosuppressants, rituximab, systemic lupus erythematosus.

Background: Ocular involvement in Psoriatic Arthritis (PsA) patients is mainly associated with uveitis but there remains a paucity of data on dry eye and retinal abnormalities. We aimed to analyze dry eye and subclinical retinal abnormalities in a cohort of PsA patients sine-psoriasis (PsO)., Methods: PsA patients sine-PsO were enrolled. Best-corrected-visual-acuity, ocular-surface-disease-index (OSDI), Schirmer test, tear film breakup-time, standard-automated-perimetry (SAP, mean deviation-MD, pattern standard deviation-PSD), fundus-perimetry (FP), and spectral-domain-optical-coherence-tomography (SD-OCT) were performed., Results: A total of 80 eyes from 40 PsA patients with moderate-severe disease activity, and 70 eyes from 35 healthy control (HC) were evaluated. Higher dry eye prevalence occurred in PsA than HC ( p < 0.0001). ESR was positively related with OSDI ( p < 0.001) and negatively related with Schirmer ( p = 0.007). In PsA, SAP registered higher MD ( p < 0.0001) and higher PSD ( p = 0.005) in comparison with HC. PSD resulted positively correlated with ESR ( p = 0.04) and CRP ( p = 0.01), while MD showed a negative correlation with CRP ( p = 0.01). Both FP mean differential sensitivity and mean defect were lower in PsA then HC ( p < 0.0001). In PsA, FP differential sensitivity was directly related with cumulative steroids ( p = 0.02)., Conclusions: In PsA patients sine-PsO, dry eye and subclinical abnormalities in visual functions occurred being potentially related to systemic inflammation., Competing Interests: The authors declare no conflict of interest.

Introduction: Spondyloarthrits (SpA) share clinical, genetic and immunological features with Inflammatory Bowel Diseases (IBD), and enteropathic SpA (eSpA) represent the clinical evidence of the association between gut and joint diseases. This cross-sectional study aimed to report data of eSpA patients collected from the first Italian database., Patients and Methods: A specific web-based interface has been created to insert and collect the main clinical, serologic and imaging data from patients with eSpA, as well as disease activity, comorbidities and treatment, in a real-life scenario., Results: Data were collected in 14 Italian centers (7 rheumatology and 7 gastroenterology units). A total of 347 eSpA patients were enrolled in the study. Type 1 peripheral eSpA was the most frequent form. Crohn' Disease (CD) was the most represented IBD. CD activity was similar among eSpA, whereas UC activity was slightly higher in the axial and mixed form than in the peripheral eSpA. The disease was active in less than half of axial eSpA patients and in only 18% of patients with peripheral eSpA. Furthermore, most of the patients had an inactive IBD. Nineteen percent of the total eSpA patients were free of therapy at the time of the enrollment and 61% of the patients were receiving biotechnological agents., Conclusions: The multidisciplinary management of eSpA patients, favored by this ad hoc created web-based platform, allowed to obtain data from the largest eSpA cohort. The information coming of this database might advance knowledge of eSpA and improve their standard of care., (Copyright © 2019 The Authors. Published by Elsevier B.V. All rights reserved.)

Objectives: The aim of this 2-year prospective study was to assess the diagnostic and therapeutic effect of a combined gastro-rheumatological approach in enteropathic spondyloarthritis (eSpA) patients., Methods: Inflammatory bowel disease (IBD) patients with joint pain were referred by IBD-dedicated gastroenterologists to a dedicated rheumatologist. At baseline and at 3, 6, 12, 24 months, the following parameters were recorded: clinical and biochemical variables, SpA and IBD activity scores, treatment (conventional synthetic; csDMARDs, biologics; bDMARDs). Associations between treatment and patient characteristics were evaluated by logistic regression (AOR [95% CI])., Results: Overall, 229 IBD patients were referred to rheumatologists. eSpA was diagnosed in 147 (64.2%) patients: 96 (65.3%) showing peripheral and 51 (34.7%) axial involvement. IBD included Crohn's disease (CD) in 141 (61.6%) and ulcerative colitis (UC) in 88 (38.4%). bDMARD treatment increased over the follow-up (baseline-24 months: 32.7-60%; AOR 3.45 [1.93-6.2], p<0.001). bDMARD use was less frequent in elderly patients (AOR 0.73 [0.56-0.96], p=0.023), in UC (AOR 0.43 [0.2-0.94], p=0.034) and in patients with peripheral involvement (AOR 0.53 [0.3-1.04], p=0.067). csDMARD use was increased in patients with peripheral involvement (AOR 4.65 [2.09-10.33], p<0.001) and in UC (AOR 2.30 [1.13-4.67], p=0.021). CRP, ESR, ASDAS-ESR levels and BASFI significantly decreased over the follow-up, whereas the pMayo score, BASDAI and HAQ-S were unchanged., Conclusions: In this prospective study in eSpA patients, a multidisciplinary approach was shown to optimise the therapeutic management and outcome (e.g. disease activity scores). bDMARD use paralleled an improvement in disease activity scores and confirmed a good safety profile.

Rheumatoid Arthritis (RA) is a chronic inflammatory disease characterized by a heterogeneous clinical response to the different treatments. Some patients are difficult to treat and do not reach the treatment targets as clinical remission or low disease activity. Known negative prognostic factors, such as the presence of auto-antiantibodies and joint erosion, the presence of a genetic profile, comorbidities and extra-articular manifestations, pregnancy or a pregnancy wish may concur to the treatment failure. In this review we aimed at identify difficult to treat RA patients and define the optimal therapeutic and environmental targets. Genetic markers of severity such as HLA-DRB1, TRAF1, PSORS1C1 and microRNA 146a are differently associated with joint damage; other gene polymorphisms seem to be associated with response to biologic disease modifying anti-rheumatic drugs (bDMARDs). The presence of comorbidities and/or extra-articular manifestations may influence the therapeutic choice; overweight and obese patients are less responsive to TNF inhibitors. In this context the patient profiling can improve the clinical outcome. Targeting different pathways, molecules, and cells involved in the pathogenesis of RA may in part justify the lack response of some patients. An overview of the future therapeutic targets, including bDMARDs (inhibitors of IL-6, GM-CSF, matrix metalloproteinases, chemokines) and targeted synthetic DMARDs (filgotinib, ABT-494, pefacitinib, decernotinib), and environmental targets is addressed. Environmental factors, such as diet and cigarette smoke, may influence susceptibility to autoimmune diseases and interfere with inflammatory pathways. Mediterranean diet, low salt intake, cocoa, curcumin, and physical activity seem to show beneficial effects, however studies of dose finding, safety and efficacy in RA need to be performed., (Copyright © 2019 Elsevier B.V.

Systemic Lupus Erythematosus (SLE) is a connective tissue disease that involves multiple organs. Ocular structures and visual pathways can be affected in SLE because of disease-related eye involvement or drug toxicity. All the part of the eye may be interested with an external, anterior involvement, responsible of the dry eye disease, or posterior (retina) and neuro-ophtalmic manifestations. Retinopathy in SLE is suggestive of high disease activity being a marker of poor visual outcome and prognosis for survival. The early diagnosis is thus the key to a better management and successful treatment. Antimalarial drugs are the cornerstone of SLE treatment and recently the American Academy of Ophthalmology updated the recommendations for hydroxychloroquine retinal toxicity screening which includes the standard automated visual fields and the spectral domain optical coherent tomography. More recently new imaging techniques have been investigated to assess retinal function and reveal subclinical eye involvement. In this review we focalize on the evidence of eye manifestations in SLE, the eye drug toxicity related to antimalarial agents and steroids, and the methods employed for the eye screening. Moreover, the future perspectives on new techniques, such as the optical coherence tomography angiography, are dissected giving new insights on evaluation of microvasculature of the retina and choroid in SLE., (Copyright © 2019 Elsevier B.V.

Background: Retinal involvement in systemic lupus erythematosus (SLE) and Sjögren syndrome (SS) may be subclinical and thus underdiagnosed., Objectives: We aimed at evaluating morphological and functional visual abnormalities in a cohort of SLE and SS patients in the absence of an overt clinical visual impairment. We also investigated potential associations between retinal disorders and disease activity, organ involvement, and treatment with steroid and/or hydroxychloroquine., Methods: The study comprised 42 SLE and 36 primary SS patients and 76 healthy controls (HC). Ophthalmological examination, standard automated perimetry, spectral-domain optical coherence tomography, and fundus perimetry were performed., Results: Retinal thickness of the posterior pole was not different between SLE and HC groups, but it was reduced in the SS group compared with both the HC and the SLE group. In SLE and SS patients, mean defect and pattern standard deviation by standard automated perimetry were higher than in HC. Visual field index values were lower in both SLE and SS patients than in HC. SLE patients with nephritis displayed increased mean defect and pattern standard deviation and reduced visual field index values compared to patients without nephritis. In SLE and SS patients, fundus perimetry differential sensitivity was reduced, and mean defect values were higher than in HC. Disturbances in fundus perimetry in the SLE group were more prevalent in steroid-naïve patients and in SS patients who received a cumulative hydroxychloroquine dose > 1,000 g., Conclusions: Functional eye impairment was demonstrated in SLE patients, possibly associated with kidney involvement. In SLE, corticosteroids might exert a protective role. Morphological alterations and functional impairment were detected in SS patients, which may be linked to hydroxychloroquine toxicity., (© 2018 S. Karger AG, Basel.)

Allergic bronchopulmonary aspergillosis (ABPA) is a hypersensitivity reaction to Aspergillus that mainly affects patients with asthma. For diagnosis, elevated serum IgE level are needed according to Greenberger and Patterson criteria. We report a case of 43 years-old woman who developed ABPA with productive cough, fever and radiological findings of multiple confluent areas of consolidation in both upper lobes. Laboratory tests showed elevated peripheral eosinophil counts (9.3 x 10(3)/ml). In bronchial washing A. galactomannans and A. Fumigatus were isolated, although we found normal levels of serum IgE, and the absence of serum IgG and IgE antibodies to Aspergillus and A. galactomannans. In conclusion, clinical and radiological signs of ABPA can be associated with Aspergillus infection also in the absence of a specific serum antibody reaction.
