Giovanni di Dio, Florence, Italy Objective: To propose appropriate statements that drive the choice of biologic therapies in patients with rheumatoid arthritis (RA), factoring in their impact on the following issues: anti-drug antibody (ADAb) formation, suspicion and management of infections, lupus-like syndrome (LLS), effects on bone mass and sexual sphere, and relationship between RA and periodontal disease (PD). Methods: An overview of existing evidence was undertaken by an expert panel on behalf of the Italian board for the TAilored BIOlogic therapy (ITABIO). Data were extracted from controlled trials, national registries, national health care databases, post-marketing surveys, and, when required by the paucity of controlled studies, from open-label clinical series. Anti-tumor necrosis factor (anti-TNF) and non-anti-TNF-targeted biologics approved for RA were investigated. Results: ADAb formation is chiefly associated with anti-TNFs, and it is reduced by combination therapy with methotrexate. To date, ADAb titration is not advisable for clinical practice, and, in case of anti-TNF secondary failure, a non-anti-TNF biologic is indicated. LLS is observed in anti-TNF receivers and, in most cases, resolves without anti-TNF withdrawal. A non-anti-TNF biologic is advisable in patients experiencing LLS. Non-anti-TNFs demonstrated a low or absent infection risk and are preferable in patients with comorbidities. Due to their positive effects on bone mass, anti-TNFs are indicated in women at osteoporosis risk, whereas non-anti-TNF have been poorly investigated. The emerging evidence of the relationship between RA and PD and the effects on anti-TNF efficacy should lead clinicians to consider the periodontal status in RA patients. Anti-TNFs may exert a positive effect on fertility and sexuality, and clinicians should explore these aspects in RA patients. Conclusion: The optimization of biologic therapies by taking into proper account the above issues would improve patient outcomes. Keywords: biologics, immunogenicity, infections, lupus-like syndrome, osteoporosis, periodontal disease, sexuality

Background: Some myopathies can lead to dropped head or bent spine syndrome (DH/BS). The significance of this symptom has not been studied in inflammatory myopathies (IM)., Objectives: To assess the significance of DH/BS in patients with IM., Methods: Practitioners from five IM networks were invited to report patients with IM suffering from DH/BS (without other known cause than IM). IM patients without DH/BS, randomly selected in each participating centre, were included as controls at a ratio of 2 to 1., Results: 49 DH/BS-IM patients (DH: 57.1%, BS: 42.9%) were compared with 98 control-IM patients. DH/BS-IM patients were older (65 years vs 53 years, p<0.0001) and the diagnosis of IM was delayed (6 months vs 3 months, p=0.009). Weakness prevailing in the upper limbs (42.9% vs 15.3%), dysphagia (57.1% vs 25.5%), muscle atrophy (65.3% vs 34.7%), weight loss (61.2% vs 23.5%) and loss of the ability to walk (24.5% vs 5.1%) were hallmarks of DH/BS-IM (p≤0.0005), for which the patients more frequently received intravenous immunoglobulins (65.3% vs 34.7%, p=0.0004). Moreover, DH/BS-IM patients frequently featured signs and/or complications of systemic sclerosis (SSc), fulfilling the American College of Rheumatology/European Alliance of Associations for Rheumatology criteria for this disease in 40.8% of the cases (vs 5.1%, p<0.0001). Distribution of the myopathy, its severity and its association with SSc were independently associated with DH/BS (p<0.05). Mortality was higher in the DH/BS-IM patients and loss of walking ability was independently associated with survival (p<0.05)., Conclusion: In IM patients, DH/BS is a marker of severity and is associated with SSc (scleromyositis)., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: Immune and vascular ageing are proposed risk factors for giant cell arteritis (GCA). Data on the impact of age at diagnosis of GCA on the clinical presentation and course of the disease are scarce., Methods: Patients with GCA followed at referral centres within the Italian Society of Rheumatology Vasculitis Study Group were enrolled up to November 2021. Patients were grouped according to age at diagnosis: ≤64, 65-79 and ≥80 years old., Results: The study included 1004 patients, mean age 72.1±8.4, female 70.82%. Median follow-up duration was 49 (IQR 23-91) months. Patients in the oldest group (≥80 years) had significantly more cranial symptoms, ischaemic complications and risk for blindness compared with the groups 65-79 and ≤64 years (blindness: 36.98% vs 18.21% vs 6.19%; p<0.0001). Large-vessel-GCA was more frequent in the youngest group (65% of patients). Relapses occurred in 47% of patients. Age did not influence the time to first relapse, nor the number of relapses. Older age was negatively associated with the number of adjunctive immunosuppressants. Patients >65 years old had 2-3 fold increased risk for aortic aneurysm/dissection up to 60 months follow-up. Serious infections, but not other treatment-related complications (hypertension, diabetes, osteoporotic fractures), were significantly associated with older age. Mortality occurred in 5.8% of the population with age >65, cranial and systemic symptoms as independent risk factors., Conclusions: The highest risk of ischaemic complications, aneurysm development, serious infections and the possible undertreatment make of GCA a very challenging disease in the oldest patients., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Objectives: Interstitial lung disease (ILD) has been described as a possible pulmonary involvement in antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitides (AAV), mainly granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA). Aim of this cross-sectional Italian national study was to describe demographic, clinical and serological profile of ILD related to MPA and GPA and investigate possible correlations between radiologic patterns of ILD and vasculitis features., Methods: We enrolled 95 consecutive patients with AAV-ILD, 56 affected by MPA (58.9%) and 39 by GPA (41.1%)., Results: NSIP was the most frequently detected ILD pattern, observed in c-ANCA patients in 60.9% of cases, followed by UIP pattern mainly observed in p-ANCA patients (47.7%, p=0.03). ILD represented the first clinical manifestation, preceding vasculitis diagnosis in 22.1% of cases and, globally, ILD was already detectable at AAV diagnosis in 66.3% of patients. The diagnosis of ILD preceded that of AAV in 85.7% of p-ANCA positive-patients, while only one patient with c-ANCA developed ILD before AAV (p= 0.039). Multivariate analysis confirmed the correlation of UIP pattern with p-ANCA-positivity and a diagnosis of ILD before AAV, also when adjusted for age and sex., Conclusions: Our study confirms that UIP is a frequent pattern of lung disease in AAVILD patients. Our results also suggest that ILD can represent an early complication of AAV but also occur in the course of the disease, suggesting the need of a careful evaluation by both pulmonologist and rheumatologist to achieve an early diagnosis. Further prospective studies are needed to define ILD prevalence and evolution in AAV patients.

Objectives: To define the clinical spectrum time-course and prognosis of non-Asian patients positive for anti-MDA5 antibodies., Methods: We conducted a multicentre, international, retrospective cohort study., Results: 149 anti-MDA5 positive patients (median onset age 53 years, median disease duration 18 months), mainly females (100, 67%), were included. Dermatomyositis (64, 43%) and amyopathic dermatomyositis (47, 31%), were the main diagnosis; 15 patients (10%) were classified as interstitial pneumonia with autoimmune features (IPAF) and 7 (5%) as rheumatoid arthritis. The main clinical findings observed were myositis (84, 56%), interstitial lung disease (ILD) (108, 78%), skin lesions (111, 74%), and arthritis (76, 51%). The onset of these manifestations was not concomitant in 74 cases (50%). Of note, 32 (21.5%) patients were admitted to the intensive care unit for rapidly progressive-ILD, which occurred in median 2 months from lung involvement detection, in the majority of cases (28, 19%) despite previous immunosuppressive treatment. One-third of patients (47, 32% each) was ANA and anti-ENA antibodies negative and a similar percentage was anti-Ro52 kDa antibodies positive. Non-specific interstitial pneumonia (65, 60%), organising pneumonia (23, 21%), and usual interstitial pneumonia-like pattern (14, 13%) were the main ILD patterns observed. Twenty-six patients died (17%), 19 (13%) had a rapidly progressive-ILD., Conclusions: The clinical spectrum of the anti-MDA5 antibodies-related disease is heterogeneous. Rapidly-progressive ILD deeply impacts the prognosis also in non-Asian patients, occurring early during the disease course. Anti-MDA5 antibody positivity should be considered even when baseline autoimmune screening is negative, anti-Ro52 kDa antibodies are positive, and radiology findings show a NSIP pattern.

Background: Few studies have evaluated the effectiveness of adalimumab in the real-life setting in psoriatic arthritis (PsA). Objective: To evaluate the 2-year retention rate of adalimumab in PsA patients. Potential baseline parameters influencing persistence on treatment were also evaluated. Methods: PsA patients from 16 Italian Rheumatology Units treated with adalimumab as first- or second-line biological therapy were retrospectively evaluated. Adalimumab retention rate was evaluated at 12 and 24 months. Logistic regression was used to evaluate the association between predictor variables and adalimumab retention rate. Results: From 424 patients (53.5% male, aged 48.3 ± 12.8 years) who started treatment with adalimumab, 367 (86.6%) maintained treatment for 12 months and 313 (73.8%) for 2 years. At 24-months, Disease Activity in PsA (DAPSA) remission (defined as ≤4) and Low Disease Activity (LDA) (≤14) were achieved in 22.8% and 44.4% of patients, respectively. Adalimumab treatment significantly decreased the number of tender (7.0 ± 5.7 at baseline vs. 2.3 ± 3.5 at 24 months, p < 0.001) and swollen joints (2.7 ± 2.8 at baseline vs. 0.4 ± 0.9 at 24 months, p < 0.001), DAPSA (25.5 ± 10.9 at baseline vs. 11.0 ± 8.4 at 24 months, p < 0.001), PASI (5.3 ± 5.7 at baseline vs. 2.7 ± 2.8 at 24 months, p < 0.001) and CRP (3.8 ± 6.3 at baseline vs. 1.2 ± 1.7 at 24 months, p < 0.001). Among a range of laboratory and clinical variables, only female gender was associated with improved adalimumab persistence at 24 months (OR: 1.98, 95% CI: 1.2-3.2, p = 0.005). Conclusions: Independent of a range of predictor variables, adalimumab was shown to be effective, while maintaining a high retention rate after 2 years in PsA patients., (Copyright © 2019 D'Angelo, Cantini, Ramonda, Cantarini, Carletto, Chimenti, Delle Sedie, Foti, Gerli, Lomater, Lubrano, Marchesoni, Zabotti, Salvarani, Scrivo, Scarpa, Tramontano, Nannini, Lorenzin, Fabbroni, Martinis, Perricone, Carli, Visalli, Rovera, Perrotta, Quartuccio, Altobelli, Costa, Niccoli, Ortolan and Caso.)

Objective: To explore the role of smoking and obesity in primary Sjögren syndrome (pSS)., Methods: Olmsted County (Minnesota, USA) residents (n = 106) diagnosed with pSS from 2000 to 2015 were compared to 3 controls without pSS and matched for age and sex who were randomly selected from Olmsted County residents., Results: Current smokers were less likely to be pSS cases (OR 0.34, 95% CI 0.14-0.85), while there was no association between former smoking and case/control status (OR 1.27, 95% CI 0.80-2.03) compared to never smokers. Smoking status was not associated with antinuclear antibody, anti-SSA, anti-SSB, or rheumatoid factor positivity (p > 0.05). OR for obesity was 0.79 (95% CI 0.48-1.30)., Conclusion: In this population-based study, current smoking was inversely associated with case/control status, while body mass index lacked any association.

Introduction: Latent tuberculosis infection (LTBI) accounts for almost a quarter of the world population, and, in 5-10% of the subjects with impaired immune-response against M. tuberculosis growth, it may progress to active tuberculosis (TB). In this review, we focus on the need to propose a screening for LTBI including preventive therapy offer in rheumatic patients undergoing therapy with biological drugs. Areas covered: We report on evidence that biologics are associated with an increased risk of active TB reactivation. This effect seems to be mainly limited to treatment with anti-tumor necrosis factor (TNF) agents, while non-anti-TNF-targeted biologics are not likely associated to any increased risk. We introduce the concept that the patients' coexisting host-related risk factors, such as comorbidities, are crucial to identify those at higher risk to reactivate TB. We report that preventive TB therapy is well tolerated in patients treated with biological drugs. Expert commentary: Availability of non-anti-TNF targeted biologics, that are not associated with an increased risk of TB reactivation, offers a great opportunity to tailor a therapeutic intervention at low/absent TB risk. After proper LTBI screening investigations, preventive TB therapy has been demonstrated to be effective and well-tolerated to reduce the risk of TB reactivation in rheumatic patients requiring biological drugs.

Objective: To determine rates and primary discharge diagnoses of hospitalisation in a cohort of patients with incident primary Sjögren's syndrome (pSS) compared with the general population., Methods: This was a retrospective population-based cohort study focused on Olmsted County, Minnesota. The pSS cohort consisted of patients with incident pSS in the 1976-2015 period and was compared with a cohort of individuals without pSS matched 3:1 for age, sex and calendar year, randomly selected from the same population. Hospitalisations in 1995-2016 were examined. Discharge diagnoses were categorised using the Clinical Classifications Software for International Classification of Diseases, 9th revision, Clinical Modification., Results: A total of 385 hospitalisations occurred in the 160 patients with pSS during 1592 person-years of follow-up. Among 466 comparators, there were 899 hospitalisations during 4660 person-years of follow-up, resulting in a significantly higher rate of hospitalisations in patients with pSS (rate ratio (RR): 1.25, 95% CI: 1.11 to 1.41). Rates of hospitalisation were increased among patients with pSS for endocrine, nutritional and metabolic diseases and immunity disorders (RR 1.82, 95% CI 1.08 to 2.98), diseases of the musculoskeletal system and connective tissue (RR 1.49, 95% CI 1.05 to 2.05) and for injuries and poisoning (RR 1.46, 95% CI 1.01 to 2.06). While not significantly increased overall, hospitalisations for diseases of the circulatory system were significantly increased in patients with pSS aged ≥75 years (RR 1.54, 95% CI 1.11 to 2.11)., Conclusions: Patients with pSS experienced higher rates of hospitalisation than the general population. Hospitalisations for endocrine/metabolic disorders, diseases of the circulatory system, diseases of the musculoskeletal system and connective tissue disorders, and injuries were more common among patients with pSS than comparators., Competing Interests: Competing interests: None declared.

Three patients affected by Behçet's disease (BD) with severe uveitis and neurological involvement in stable clinical remission and who rapidly relapsed after switching from reference infliximab (re-IFX) to biosimilar infliximab (bio-IFX) are reported. In order to observe the rules of local health authorities, two males and one female (38, 26, and 40 years old, respectively) with BD complicated by severe uveitis and neuro-Behçet and who were in prolonged remission, were switched from re-IFX to bio-IFX, with the same dosing regimen of 5 mg/kg intravenous infusions every 8 weeks. All three patients experienced disease flare-ups, with recurrence of uveoretinitis in the first patient, neuro-Behçet in the second, and uveitis and neuro-Behçet in the third after 1, 3, and 2 infusions, respectively. After appropriate washout of re-IFX, all three patients were administered subcutaneous adalimumab, with a dosing regimen of 40 mg/fortnight, and a good response was achieved. Our three patients with BD experienced a rapid disease relapse after switching from re-IFX to bio-IFX, possibly due to cross-reaction of anti-IFX antibodies. This outcome suggests the necessity to exercise caution regarding the automatic substitution of re-IFX with bio-IFX in patients achieving remission with re-IFX., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors.

Objective: The Italian board for the TAilored BIOlogic therapy (ITABIO) reviewed the most consistent literature to indicate the best strategy for the second-line biologic choice in patients with rheumatoid arthritis (RA), spondyloarthritis (SpA), and psoriatic arthritis (PsA)., Methods: Systematic review of the literature to identify English-language articles on efficacy of second-line biologic choice in RA, PsA, and ankylosing spondylitis (AS). Data were extracted from available randomized, controlled trials, national biologic registries, national healthcare databases, post-marketing surveys, and open-label observational studies., Results: Some previously stated variables, including the patients׳ preference, the indication for anti-tumor necrosis factor (TNF) monotherapy in potential childbearing women, and the intravenous route with dose titration in obese subjects resulted valid for all the three rheumatic conditions. In RA, golimumab as second-line biologic has the highest level of evidence in anti-TNF failure. The switching strategy is preferable for responder patients who experience an adverse event, whereas serious or class-specific side effects should be managed by the choice of a differently targeted drug. Secondary inadequate response to etanercept (ETN) should be treated with a biologic agent other than anti-TNF. After two or more anti-TNF failures, the swapping to a different mode of action is recommended. Among non-anti-TNF targeted biologics, to date rituximab (RTX) and tocilizumab (TCZ) have the strongest evidence of efficacy in the treatment of anti-TNF failures. In PsA and AS patients failing the first anti-TNF, the switch strategy to a second is advisable, taking in account the evidence of adalimumab efficacy in patients with uveitis. The severity of psoriasis, of articular involvement, and the predominance of enthesitis and/or dactylitis may drive the choice toward ustekinumab or secukinumab in PsA, and the latter in AS., Conclusion: Taking in account the paucity of controlled trials, second-line biologic therapy may be reasonably optimized in patients with RA, SpA, and PsA., (Copyright © 2017 Elsevier Inc.

Objective: To evaluate the frequency of dactylitis, enthesitis, and anterior uveitis (AU) in spondyloarthritis (SpA) associated with inflammatory bowel disease (IBD-SpA) compared with other SpA, and to assess the role of associated psoriasis in the occurrence of dactylitis and enthesitis., Methods: In a 12-month case-control study, the frequency of dactylitis and enthesitis in 29 patients with ulcerative colitis (UC) and 59 with Crohn disease (CD) who satisfied the Spondyloarthritis international Society criteria for axial or peripheral SpA was compared with 176 controls, including 97 (55.1%) with psoriatic arthritis (PsA), 47 (26.7%) with ankylosing spondylitis (AS), and 32 (18.2%) with nonradiographic axial SpA (nr-axSpA). The occurrence of these features in IBD-SpA with and without psoriasis was also evaluated., Results: Axial, peripheral, or mixed involvement was observed in 46 (52%), 29 (33%), and 13 (15%) patients, respectively; and 14/88 (16%) had psoriasis. Dactylitis was recorded in 4/88 patients (4.5%) with IBD-SpA and in 30 controls (17.4%; p = 0.008), enthesitis in 16 cases (18.1%) and in 78/176 controls (44.3%; p < 0.001), and AU in 3 patients (3.4%) with IBD-SpA and in 26 controls (14.7%; p = 0.01). No significant differences were found between patients with UC-SpA and those with CD-SpA. Dactylitis and enthesitis were significantly more common in patients with IBD-SpA who also had psoriasis compared to those without skin disease (p = 0.009 and 0.003, respectively)., Conclusion: Dactylitis, enthesitis, and AU are significantly less frequent in IBD-SpA compared with other types of SpA. Given the frequent association of psoriasis and IBD, overlooking coexistent skin disease may lead to overestimating the frequency of these features.

Tuberculosis (TB) still represents an important issue for public health in underdeveloped countries, but the use of antitumor necrosis factor agents (anti-TNF) for the treatment of inflammatory rheumatic disorders has reopened the problem also in countries with low TB incidence, due to the increased risk of TB reactivation in subjects with latent tuberculosis infection (LTBI). Over the last 5 years, several non-anti-TNF-targeted biologics have been licensed for the treatment of rheumatoid arthritis, ankylosing spondylitis, and psoriatic arthritis. We reviewed the epidemiology of TB, the role of different cytokines and of the immune system cells involved in the immune response against TB infection, the methods to detect LTBI, and the risk of TB reactivation in patients exposed to non-anti-TNF-targeted biologics. Given the limited role exerted by the cytokines different from TNF, as expected, data from controlled trials, national registries of biologics, and postmarketing surveillance show that the risk of TB reactivation in patients receiving non-anti-TNF-targeted biologics is negligible, hence raising the question whether the screening procedures for LTBI would be necessary.

Objective: A multidisciplinary expert panel, the Italian board for the TAilored BIOlogic therapy (ITABIO), was constituted to formulate evidence-based decisional statements for the first-line tailored biologic therapy in patient with rheumatoid arthritis (RA), spondyloarthritis (SpA), and psoriatic arthritis (PsA)., Methods: Systematic review of the literature to identify English-language articles on the variables influencing the first-line biologic choice, including the efficacy and safety of the drug, the route of administration, the availability of response predictor biomarkers, the need of monotherapy, the patient socio-economic status, lifestyle, cultural level, personality, fertility and childbearing potential in women, the presence of comorbidities, the host-related risk factors for infection and latent tuberculosis infection (LTBI) reactivation, the cardiovascular (CV) risk, and costs., Results: Some variables, including the patients' preference, the indication for anti-TNF monotherapy in potential childbearing women, and the intravenous route with dose titration in obese subjects resulted valid for all the three rheumatic conditions. Further, evidence of a better cost-effectiveness profile for etanercept (ETN) and biosimilar infliximab (IFX) in RA was found. Any biologic may be employed in absence of choice driving factors in RA. Otherwise, a high infection risk or LTBI positivity drive the choice toward abatacept (ABA), tocilizumab (TCZ), or ETN. TCZ should be the first choice if monotherapy is required. High rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA) titers should drive the choice toward TCZ or ABA, while in patients at high CVD risk anti-TNF choice, with preference for ETN, seems appropriate. Presence of anterior uveitis or inflammatory bowel disease drives the choice to monoclonal antibody anti-TNFs (MoAb anti-TNFs). In PsA, ustekinumab (UTK), and to a lesser extent ETN, represents the first choice in patients at high infection and TB risk. Anti-TNFs or UTK choice is guided by skin or articular disease severity, enthesitis, and dactylitis, whereas ETN should be preferred if metabolic syndrome or high CV risk complicate PsA., Conclusion: Taking in account of multiple choice driving variables, first-line biologic therapy may be optimized in patients with RA, SpA, and PsA., (Copyright © 2016 Elsevier Inc.

Background: Asbestosis is characterized by lung and pleural fibrosis and by immune system dysregulation, with autoantibody production and systemic immune-mediated disease. No specific therapies are available for asbestosis. Recently, the pivotal pathogenic role exerted by interleukin-1beta has been recently reported., Case Presentation: We treated with anti-interleukin 1 beta targeted antibody canakinumab a 67 year old man with asbestosis and long lasting systemic autoimmune features. A dramatic improvement in clinical manifestations was observed at 1 week after the first injection, with complete clinical remission at 4 months., Conclusion: This case suggests new perspectives for the treatment of asbestosis and its systemic features.
