RESUMEN
Uncontrolled complement activation can cause or contribute to glomerular injury in multiple kidney diseases. Although complement activation plays a causal role in atypical hemolytic uremic syndrome and C3 glomerulopathy, over the past decade, a rapidly accumulating body of evidence has shown a role for complement activation in multiple other kidney diseases, including diabetic nephropathy and several glomerulonephritides. The number of available complement inhibitor therapies has also increased during the same period. In 2022, Kidney Diseases: Improving Global Outcomes (KDIGO) convened a Controversies Conference, "The Role of Complement in Kidney Disease," to address the expanding role of complement dysregulation in the pathophysiology, diagnosis, and management of various glomerular diseases, diabetic nephropathy, and other forms of hemolytic uremic syndrome. Conference participants reviewed the evidence for complement playing a primary causal or secondary role in progression for several disease states and considered how evidence of complement involvement might inform management. Participating patients with various complement-mediated diseases and caregivers described concerns related to life planning, implications surrounding genetic testing, and the need for inclusive implementation of effective novel therapies into clinical practice. The value of biomarkers in monitoring disease course and the role of the glomerular microenvironment in complement response were examined, and key gaps in knowledge and research priorities were identified.

PURPOSE OF REVIEW: Cryoglobulinemic vasculitis (CV) is an immune complex mediated small vessel vasculitis characterized by the presence of cryoglobulins in serum, often associated with hepatitis C infection, systemic autoimmune diseases or hematological conditions. The focus of this review is to provide an update on new insights into pathogenesis, epidemiology and therapies of infectious and noninfectious type II and type III CV. RECENT FINDINGS: The introduction of new antiviral drugs for treatment of hepatitis C infection implied major changes in HCV-related CV, allowing to shed new lights on CV pathogenesis and mechanisms of relapse and, therefore, to increase the relevance of autoimmune diseases in CV epidemiology. Specific B-cell clones are involved in the production of pathogenic immune complexes that leads to small-vessel vasculitis. Therefore, both antiviral treatments [direct-acting antivirals (DAAs) and oral nucleot(s)ide analogues] and targeted anti-CD20 therapies (rituximab) prove to be safe and effective options, leading to a better prognosis. Association of Sjögren syndrome and CV defines a specific phenotype of patients, characterized by severe manifestations and poor outcome. SUMMARY: Removing viral stimulation on B-cells through direct-acting antivirals and blocking B-cells proliferation and differentiation with rituximab are the goals of treatment of CV. However, further research is needed to identify prognostic factors of refractory and relapsing disease.

BACKGROUND: Baricitinib is an oral selective inhibitor of Janus kinase 1 and 2 approved for the treatment of rheumatoid arthritis, atopic dermatitis, and alopecia areata. In a 24-week phase 2 study in patients with systemic lupus erythematosus (SLE), baricitinib 4 mg significantly improved SLE disease activity compared with placebo. The objective of this trial was to evaluate the efficacy and safety of baricitinib in patients with active SLE in a 52-week phase 3 study. METHODS: In a multicentre, double-blind, randomised, placebo-controlled, parallel-group, phase 3 study, SLE-BRAVE-I, patients (aged ≥18 years) with active SLE receiving stable background therapy were randomly assigned 1:1:1 to baricitinib 4 mg, 2 mg, or placebo once daily for 52 weeks with standard of care. Glucocorticoid tapering was encouraged but not required per protocol. The primary endpoint was the proportion of patients reaching an SLE Responder Index (SRI)-4 response at week 52 in the baricitinib 4 mg treatment group compared with placebo. The primary endpoint was assessed by logistic regression analysis with baseline disease activity, baseline corticosteroid dose, region, and treatment group in the model. Efficacy analyses were done on a modified intention-to-treat population, comprising all participants who were randomly assigned and received at least one dose of investigational product. Safety analyses were done on all randomly assigned participants who received at least one dose of investigational product and who did not discontinue from the study for the reason of lost to follow-up at the first post-baseline visit. This study is registered with ClinicalTrials.gov, NCT03616912. FINDINGS: 760 participants were randomly assigned and received at least one dose of baricitinib 4 mg (n=252), baricitinib 2 mg (n=255), or placebo (n=253). A significantly greater proportion of participants who received baricitinib 4 mg (142 [57%]; odds ratio 1·57 [95% CI 1·09 to 2·27]; difference with placebo 10·8 [2·0 to 19·6]; p=0·016), but not baricitinib 2 mg (126 [50%]; 1·14 [0·79 to 1·65]; 3·9 [-4·9 to 12·6]; p=0·47), reached SRI-4 response compared with placebo (116 [46%]). There were no significant differences between the proportions of participants in either baricitinib group reaching any of the major secondary endpoints compared with placebo, including glucocorticoid tapering and time to first severe flare. 26 (10%) participants receiving baricitinib 4 mg had serious adverse events, 24 (9%) participants receiving baricitinib 2 mg, and 18 (7%) participants receiving placebo. The safety profile of baricitinib in participants with SLE was consistent with the known baricitinib safety profile. INTERPRETATION: The primary endpoint in this study was met for the 4 mg baricitinib group. However, key secondary endpoints were not. No new safety signals were observed.

In a 24-week phase 2 study in patients with systemic lupus erythematosus (SLE), baricitinib 4 mg significantly improved SLE disease activity compared with placebo. In this Article, we report the evaluation of efficacy and safety of baricitinib in patients with SLE in a 52-week phase 3 study. METHODS: In this phase 3 double-blind, randomised, placebo-controlled study, SLE-BRAVE-II, patients (aged ≥18 years) with active SLE receiving stable background therapy were randomly assigned 1:1:1 to baricitinib 4 mg, baricitinib 2 mg, or placebo once daily for 52 weeks. The primary endpoint was the proportion of patients with an SLE Responder Index (SRI)-4 response at week 52 in the baricitinib 4 mg treatment group compared with placebo. Glucocorticoid tapering was encouraged but not required per protocol. The primary endpoint was assessed by logistic regression analysis with baseline disease activity, baseline corticosteroid dose, region, and treatment group in the model. Efficacy analyses were done on an intention-to-treat population, comprising all participants who were randomly assigned and received at least one dose of investigational product and who did not discontinue from the study for the reason of lost to follow-up at the first post-baseline visit. Safety analyses were done on all randomly assigned participants who received at least one dose of investigational product and who did not discontinue. This study is registered with ClinicalTrials.gov, NCT03616964, and is complete. FINDINGS: A total of 775 patients were randomly assigned and received at least one dose of baricitinib 4 mg (n=258), baricitinib 2 mg (n=261), or placebo (n=256). There was no difference in the primary efficacy outcome of the proportion of SRI-4 responders at week 52 between participants who received baricitinib 4mg (121 [47%]; odds ratio 1·07 [95% CI 0·75 to 1·53]; difference with placebo 1·5 [95% CI -7·1 to 10·2]), 2 mg (120 [46%]; 1·05 [0·73 to 1·50]; 0·8 [-7·9 to 9·4]) and placebo (116 [46%]). None of the major secondary endpoints, including glucocorticoid tapering and time to first severe flare, were met. Serious adverse events were observed in 29 (11%) participants in the baricitinib 4 mg group, 35 (13%) in the baricitinib 2 mg group, and 22 (9%) in the placebo group. The safety profile of baricitinib in patients with SLE was consistent with the known baricitinib safety profile. INTERPRETATION: Although phase 2 data suggested baricitinib as a potential treatment for patients with SLE, which was supported in SLE-BRAVE-I, this result was not replicated in SLE-BRAVE-II. No new safety signals were observed. FUNDING: Eli Lilly and Company.

OBJECTIVES: To investigate the frequency and factors associated with disease flare following vaccination against SARS-CoV-2 in people with inflammatory/autoimmune rheumatic and musculoskeletal diseases (I-RMDs). METHODS: Data from the European Alliance of Associations for Rheumatology Coronavirus Vaccine physician-reported registry were used. Factors associated with flare in patients with I-RMDs were investigated using multivariable logistic regression adjusted for demographic and clinical factors. RESULTS: The study included 7336 patients with I-RMD, with 272 of 7336 (3.7%) experiencing flares and 121 of 7336 (1.6%) experiencing flares requiring starting a new medication or increasing the dosage of an existing medication. Factors independently associated with increased odds of flare were: female sex (OR=1.40, 95% CI=1.05 to 1.87), active disease at the time of vaccination (low disease activity (LDA), OR=1.45, 95% CI=1.08 to 1.94; moderate/high disease activity (M/HDA), OR=1.37, 95% CI=0.97 to 1.95; vs remission), and cessation/reduction of antirheumatic medication before or after vaccination (OR=4.76, 95% CI=3.44 to 6.58); factors associated with decreased odds of flare were: higher age (OR=0.90, 95% CI=0.83 to 0.98), non-Pfizer/AstraZeneca/Moderna vaccines (OR=0.10, 95% CI=0.01 to 0.74; vs Pfizer), and exposure to methotrexate (OR=0.57, 95% CI=0.37 to 0.90), tumour necrosis factor inhibitors (OR=0.55, 95% CI=0.36 to 0.85) or rituximab (OR=0.27, 95% CI=0.11 to 0.66), versus no antirheumatic treatment. In a multivariable model using new medication or dosage increase due to flare as the dependent variable, only the following independent associations were observed: active disease (LDA, OR=1.47, 95% CI=0.94 to 2.29; M/HDA, OR=3.08, 95% CI=1.91 to 4.97; vs remission), cessation/reduction of antirheumatic medication before or after vaccination (OR=2.24, 95% CI=1.33 to 3.78), and exposure to methotrexate (OR=0.48, 95% CI=0.26 to 0.89) or rituximab (OR=0.10, 95% CI=0.01 to 0.77), versus no antirheumatic treatment. CONCLUSION: I-RMD flares following SARS-CoV-2 vaccination were uncommon. Factors associated with flares were identified, namely higher disease activity and cessation/reduction of antirheumatic medications before or after vaccination.
RESUMEN
OBJECTIVES: To update the EULAR recommendations for the management of systemic lupus erythematosus (SLE) based on emerging new evidence. METHODS: An international Task Force formed the questions for the systematic literature reviews (January 2018-December 2022), followed by formulation and finalisation of the statements after a series of meetings. A predefined voting process was applied to each overarching principle and recommendation. Levels of evidence and strengths of recommendation were assigned, and participants finally provided their level of agreement with each item. RESULTS: The Task Force agreed on 5 overarching principles and 13 recommendations, concerning the use of hydroxychloroquine (HCQ), glucocorticoids (GC), immunosuppressive drugs (ISDs) (including methotrexate, mycophenolate, azathioprine, cyclophosphamide (CYC)), calcineurin inhibitors (CNIs, cyclosporine, tacrolimus, voclosporin) and biologics (belimumab, anifrolumab, rituximab). Advice is also provided on treatment strategies and targets of therapy, assessment of response, combination and sequential therapies, and tapering of therapy. HCQ is recommended for all patients with lupus at a target dose 5 mg/kg real body weight/day, considering the individual's risk for flares and retinal toxicity. GC are used as 'bridging therapy' during periods of disease activity; for maintenance treatment, they should be minimised to equal or less than 5 mg/day (prednisone equivalent) and, when possible, withdrawn. Prompt initiation of ISDs (methotrexate, azathioprine, mycophenolate) and/or biological agents (anifrolumab, belimumab) should be considered to control the disease and facilitate GC tapering/discontinuation. CYC and rituximab should be considered in organ-threatening and refractory disease, respectively. For active lupus nephritis, GC, mycophenolate or low-dose intravenous CYC are recommended as anchor drugs, and add-on therapy with belimumab or CNIs (voclosporin or tacrolimus) should be considered. Updated specific recommendations are also provided for cutaneous, neuropsychiatric and haematological disease, SLE-associated antiphospholipid syndrome, kidney protection, as well as preventative measures for infections, osteoporosis, cardiovascular disease. CONCLUSION: The updated recommendations provide consensus guidance on the management of SLE, combining evidence and expert opinion.

SLE presents significant challenges for patients and health-care professionals (HCPs), both across Europe and worldwide. Improving health-care outcomes for patients with SLE requires a comprehensive understanding of patient disease pathways. In particular, the geographical distance between SLE patients and specialized care centres, combined with the scarcity of rheumatologists, exacerbates delays in diagnosis and management. Also, the initial SLE symptoms can often be non-specific, and providing guidelines for primary HCPs and other non-specialists is extremely important. Improvement in access to treatment is also important, with several recently approved therapies for SLE not being available in several European countries and many low- and middle-income countries (LMICs). Furthermore, in the LMICs in which these treatments are available, they are not always covered by the health-care system, making their access almost impossible for those of lower socio-economic status. A number of provisions are already in place within the European Union, to improve access to care for patients with rare and complex diseases, including those with SLE. In particular, European Reference Networks (ERNs), such the ERN for Autoimmune Diseases ReCONNET, are virtual networks involving HCPs across Europe with the aim of improving the care of patients with rare and complex diseases that require highly specialized treatment and a concentration of knowledge and resources. In addition, lupus patient organizations such as Lupus Europe play a crucial role in raising awareness of SLE and advocating for improved access to care. Together, we can work towards a future where all people living with lupus receive the comprehensive and timely care they deserve.

OBJECTIVES: In a cross-sectional study, we explored possible differences in sleep parameters between SLE patients and age- and gender-matched healthy controls through actigraphic and self-reported measures. Furthermore, we aimed to identify possible predictors of such disturbances in the patient cohort. METHODS: Participants' sociodemographic data and sleep parameters were collected. Sleep parameters were evaluated through the Pittsburgh Sleep Quality Index, the Insomnia Severity Index and 7-day actigraphic monitoring. The 10-item Perceived Stress Scale was used to investigate stress. Disease activity and daily glucocorticoid dose were assessed in SLE patients. Possible predictors of the SLE group were explored through two binomial logistic models. Within the SLE group, possible predictors of sleep parameters were tested estimating multiple linear regression models. RESULTS: A total of 40 SLE patients and 33 controls were included in the study. The SLE group showed worse sleep maintenance actigraphic parameters (i.e. sleep efficiency and wake after sleep onset), higher total sleep time and higher perceived stress. Within the SLE cohort, the daily glucocorticoids dose was associated with an impairment in sleep maintenance despite no reduction in sleep duration, typical of normal sleep duration insomnia, whereas perceived stress was associated with short sleep duration insomnia. CONCLUSION: Compared with healthy controls, SLE patients showed worse sleep quality and greater perceived stress severity. As glucocorticoids and perceived stress are associated with different types of insomnia in these patients, a multidimensional approach to both sleep characterization and therapy might be preferred.

OBJECTIVES: To describe phenotypes and outcomes of extra-renal flares in SLE, to identify clusters of extra-renal flares based on baseline features, and to develop a machine learning (ML) tool capable of predicting 'difficult to treat' (D2T) flares. METHODS: Extra-renal flares that occurred in our cohort over the last five years with at least one year of follow-up were included. Baseline clinical variables were described and flares assigned to clusters. Attainment of remission and low disease activity state (LLDAS) at 12 months were compared. Flares were then considered 'D2T' in case of non-attainment of LLDAS at 6 and 12 months. Baseline features were used to train a ML model able to predict future D2T-flares, at admission. Traditional approaches were then compared with informatic techniques. RESULTS: Among 420 SLE patients of the cohort, 114 flares occurred between 2015 and 2021; 79 extra-renal flares, predominantly mucocutaneous (24.1%) and musculoskeletal (45.6%), were considered. After 12 months, 79.4% and 49.4% were in LLDAS and in remission, respectively, while 17 flares were classified as D2T (21.5%); D2T flares received a higher cumulative and daily dose of glucocorticoids. Among the clusters, cluster 'D' (mild-moderate flares with mucocutaneous manifestations in patients with history of skin involvement) was associated with the lowest rate of remission. Among clinical data, not being on LLDAS at 3 months was the unique independent predictor of D2T flares. CONCLUSIONS: Our clusterization well separates extra-renal flares according to their baseline features and may propose a new identification standard. D2T flares, especially refractory skin manifestations, are frequent in SLE and represent an unmet need in the management of the disease as they are associated with higher glucocorticoid (GC) dosage and risk of damage accrual. Our ML model could help in the early identification of D2T flares, flagging them to elevate the attention threshold at admission.

OBJECTIVES: Oral and genital ulcers are the hallmark manifestation of Behçet's disease (BD), significantly impacting patients' quality of life. Our study focuses on comparing the effectiveness and safety of TNF inhibitors (TNFis) and apremilast in controlling oral ulcers of BD, aiming to provide evidence-based guidance for physicians in selecting appropriate treatment modalities. METHODS: A retrospective analysis was performed on BD patients treated between December 2016 and December 2021 with TNFis or apremilast for refractory oral ulcers. The study assessed treatment response by the absence of oral ulcers at 3 and 6 months, with additional evaluations for genital ulcers and articular involvement. RESULTS: The study included 78 patients, equally allocated between TNFis and apremilast treatments. Both groups showed significant oral ulcer reduction at 3 (p< 0.001) and 6 months (p= 0.01) with no significant difference between the treatments. Apremilast had a notable corticosteroid-sparing effect by the 3-month follow-up, persisting through 6 months. Both treatments were equally effective in reducing genital ulcers, with TNFis showing greater effectiveness in addressing articular involvement. Apremilast had a higher discontinuation rate due to gastrointestinal side effects. CONCLUSION: TNFis and apremilast are both effective for treating BD refractory oral ulcers. While TNFis may offer broader benefits for other disease manifestations, apremilast is distinguished by its corticosteroid-sparing effect, especially for patients with a milder disease phenotype. Treatment selection should consider individual disease severity and clinical features to ensure a personalized and effective management strategy.
RESUMEN
OBJECTIVES: The management of neuropsychiatric systemic lupus erythematosus (NPSLE) poses considerable challenges due to limited clinical trials. Therapeutic decisions are customized based on suspected pathogenic mechanisms and symptom severity. This study aimed to investigate therapeutic strategies and disease outcome for patients with NPSLE experiencing their first neuropsychiatric (NP) manifestation. METHODS: This retrospective cohort study defined NP events according to the American College of Rheumatology case definition, categorizing them into three clusters: central/diffuse, central/focal and peripheral. Clinical judgment and a validated attribution algorithm were used for NP event attribution. Data included demographic variables, SLE disease activity index, cumulative organ damage, and NP manifestation treatments. The clinical outcome of all NP events was determined by a physician seven-point Likert scale. Predictors of clinical improvement/resolution were investigated in a multivariable logistic regression analysis. RESULTS: The analysis included 350 events. Immunosuppressants and corticosteroids were more frequently initiated/escalated for SLE-attributed central diffuse or focal NP manifestations. At 12 months of follow-up, 64% of patients showed a clinical improvement in NP manifestations. Focal central events and SLE-attributed manifestations correlated with higher rates of clinical improvement. Patients with NP manifestations attributed to SLE according to clinical judgment and treated with immunosuppressants had a significantly higher probability of achieving clinical response (OR 2.55, 95%CI 1.06-6.41, p= 0.04). Age at diagnosis and focal central events emerged as additional response predictors. CONCLUSION: NP manifestations attributed to SLE by clinical judgment and treated with immunosuppressants demonstrated improved 12-month outcomes. This underscores the importance of accurate attribution and timely diagnosis of NPSLE.
RESUMEN
OBJECTIVE: Raynaud phenomenon (RP) and digital ulcers (DUs) are the main signs of digital vasculopathy in systemic sclerosis (SSc). Selexipag is an oral prostacyclin agonist approved for SSc-related pulmonary arterial hypertension. Following our previous preliminary short-course report, we herein present long-term data on selexipag safety and efficacy in the treatment of SSc digital vasculopathy. METHODS: Selexipag was administered to patients with SSc with severe digital vasculopathy refractory or with contraindication to all other vasoactive therapies. Each subject was assessed at baseline and after 3, 6, and 12 months. Clinical outcomes related to RP and DUs were evaluated along with modified Rodnan skin score of the fingers. Digital perfusion was assessed by laser speckle contrast analysis (LASCA). Nailfold videocapillaroscopy (NVC) was also performed. RESULTS: Eight patients with SSc (63% female, mean age 50.1 years) received selexipag. After 12 months of treatment, RP was reported to significantly decrease in the number of daily episodes and mean duration (P < 0.001 and P = 0.01, respectively). All patients achieved a complete healing of their DUs (P = 0.03) within 6 months. A progressive reduction of fingers skin score was observed (P = 0.03). No structural changes of capillaries were noted on NVC. Conversely, LASCA revealed an important increase in total digital perfusion (P = 0.004) despite seasonal variability. The safety profile was consistent with that reported in the literature. CONCLUSION: We observed a sustained efficacy of selexipag on SSc digital vasculopathy during 1 year of administration. Our promising results encourage the design of a new randomized controlled trial to evaluate the effect of selexipag on SSc digital vasculopathy.
RESUMEN
OBJECTIVE: To report real-world experience on the use of anifrolumab (ANI) in refractory systemic lupus erythematosus (SLE). METHODS: The present study is a multicenter, retrospective study involving 9 Italian SLE referral centers participating in a compassionate use program for the use of ANI in adult patients with active SLE in whom all the available treatment choices failed, were not tolerated, or were contraindicated. At baseline and 1, 3, 6, 9, and 12 months of treatment, overall and organ-specific disease activity, flares, daily glucocorticoid (GC) dose, and adverse events were recorded. RESULTS: A total of 26 patients were enrolled. At 4 weeks after starting ANI, a significant decrease in the Systemic Lupus Erythematosus Disease Activity Index 2000 (P = 0.01), Systemic Lupus Erythematosus-Disease Activity Score (P = 0.01), and physician global assessment (P = 0.001) was recorded, and the same trend was maintained over time. A significant reduction in Cutaneous Lupus Erythematosus Disease Area and Severity Index-activity (P < 0.001) and in tender (P = 0.03) and swollen (P = 0.02) joint counts was also recorded. At 3 months of follow-up, 33% of patients already achieved a remission state, whereas 46% were in Lupus Low Disease Activity State (LLDAS); at 6 months, 50% were in remission and 80% were in LLDAS. A significant reduction in the mean GC daily dose was observed, starting from week 4 (P = 0.04). A total of 4 disease flares according to the Safety of Estrogens in Lupus Erythematosus National Assessment-Systemic Lupus Erythematosus Disease Activity Index were recorded (3 mild-moderate and 1 severe). Overall, 4/20 patients with at least 24 weeks of follow-up (20%) were considered nonresponders. CONCLUSION: This study provides real-world experience on the use of ANI in patients with refractory SLE, confirming its rapid effectiveness and an overall acceptable safety profile.
RESUMEN
OBJECTIVES: To evaluate adherence to medication in patients with systemic autoimmune diseases (SAD), comparing pregnant and non-pregnant women. METHODS: 200 patients with SAD were consecutively enrolled, 100 pregnant and 100 non-pregnant women. Each patient completed the 8-item Morisky Medication Adherence Scale (MMAS-8), one copy for hydroxychloroquine (HCQ) and one for other treatments for rheumatic disease, and Hospital Anxiety and Depression Scale (HADS). RESULTS: No significant differences were found in ongoing therapies between pregnant and non-pregnant women. 148 patients (74.0%) were taking HCQ and 160 (80.0%) other therapies for rheumatic disease. The mean MMAS-8 score was >6 in all groups indicating a good adherence, on average. The rate of patients with good medication adherence was higher in pregnant patients (73.9% vs. 63.3% and 76.5% vs. 64.5%, for HCQ and other therapies, respectively) although this difference was not statistically significant. Eight patients had very poor medical adherence, and all were non-pregnant women. Anxiety (15% of patients) was associated to low medication adherence for drugs other than HCQ (p=0.02), while depression (4% of patients) did not seem to have an impact on adherence. CONCLUSIONS: In our cohort we recorded a good adherence to prescribed medication, although adequate adherence was not achieved in about 30% of patients, confirming that non-adherence is an important issue in SAD. It is difficult to define a profile of patients at risk of poor adherence, but it appears important to implement communication and adherence monitoring strategies since strict monitoring also during pregnancy could improve medical adherence.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with a wide range of clinical manifestations and a relapsing-remitting course. SLE pathogenesis is the result of complex interactions between ethnic, genetic, epigenetic, immunoregulatory, hormonal and environmental factors, and several aspects of these multifactorial connections are still unclear. Overall, for the disease development, an environmental trigger may induce immunological dysfunction in genetically predisposed individuals. This review aims to summarise the most relevant data on the impact of environmental factors on the incidence of SLE and on disease activity and damage in patients with an established diagnosis of SLE.

Behçet's syndrome (BS) is a rare multisystem vasculitis involving blood vessels of any size. BS aetiology is still unclear to date, and the heterogeneity of clinical expression among ethnics and genders make early diagnosis challenging. However, so far, considerable efforts have been made toward the understanding of BS, leading researchers to agree that the coexistence of some environmental triggers and a genetical susceptibility both underlie BS aetiopathogenesis. In particular, viral agents, oral microbial flora, and mucosal microbiota have been widely explored in this regard, but still no specific microorganism has been definitely linked to the disease aetiology. Likewise, the concept that some environmental factors may play a role in BS clinical presentation has emerged based on the growing evidence that disease severity is usually higher in male patients, and that diet and fatigue may be involved in disease recurrence, especially in mucocutaneous manifestations. Moreover, smoke cessation is acknowledged as a risk factor for oral ulcerations, although the underlying mechanism is still not clear. All those environmental factors play their effects through epigenetic mechanisms. The aim of this review is to discuss the evidence on the role of environmental factors in BS aetiopathogenesis and clinical course.
RESUMEN
OBJECTIVES: Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are a group of systemic pauci-immune necrotising vasculitides involving small vessels, characterised by the presence of specific ANCA autoantibodies directed to leukocyte proteinase 3 (PR3-ANCA) or myeloperoxidase (MPO-ANCA) and subdivided into three clinical entities: granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA). The aetiology of AAV is unknown and many genetic, epigenetic and environmental factors have been reported to be involved in pathogenesis. Smoking is widely recognised as a risk factor for the development of many autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus. This systematic review will analyse known data about the role of smoking in the development, clinical presentation and outcome of AAV. METHODS: Articles that examined interactions between tobacco smoking and AAV (GPA, MPA, EGPA) were included. All articles selected were in English. No limitation on publication date was established. Case reports were excluded. The systematic search was performed using PubMed/Medline and Cochrane Library databases. RESULTS: The search provided a total of 131 articles. Three studies were added, obtained from the review of the reference lists of articles. 70 were removed because they were duplicated or written in languages other than English. The title and abstract of 64 articles were screened. Of these, 30 were excluded as the title and/or abstract did not meet the inclusion criteria. Thus, 34 remained for full-text review, of which 8 were excluded. 26 articles were therefore included in this review. The role of smoking in AAV development is unclear. AAV patients current smoking appear appear to be younger and more frequently males, with a lower prevalence of EGPA and MPA than GPA. Ever smokers show higher relapse rate. Smoking seems to be associated with a higher risk of cardiovascular events during follow-up. Smokers incur an increased risk of infections. Finally, many data support smoking as a risk factor for end stage renal disease and mortality in AAV patients. CONCLUSIONS: Current data support the hypothesis that smoking influences prevalence, clinical phenotype and prognosis of ANCA-associated vasculitis. However, further studies are required to fully determine its role.

OBJECTIVES: The COVID-19 outbreak led to an increase in mental disorders, particularly post-traumatic stress disorder (PTSD), in the general population and especially in high-risk populations such as patients with rheumatologic conditions. Although these latters are considered vulnerable to developing PTSD, few specific data have been particularly reported in the framework of the pandemic. The aim of the present study was to investigate PTSD and post-traumatic stress symptoms (PTSS) in a sample of patients with systemic autoimmune disease (SAD), followed in the framework of a prospective observational study during the pandemic. METHODS: The PERMAS project is a prospective observational study including patients with SAD and involving the Rheumatology and the Psychiatric Clinics of the Azienda Ospedaliero Universitaria Pisana (AOUP, Pisa, Italy) and the Institute of Management of the Scuola Superiore Sant'Anna (Pisa, Italy). The assessments included: a data-sheet for sociodemographic and clinical characteristics; the Trauma and Loss Spectrum-Self Report (TALS-SR) and the Impact of Event Scale-Revised (IES-R), for PTSD and PTSS; the 36-item Short Form Survey (SF-36) to assess quality of life. RESULTS: The total sample consisted of 252 patients with SAD, including 131 with connective tissue disease, 101 with arthritis and 20 with systemic vasculitis. The diagnostic groups differed significantly in age (p<0.001), gender (p<0.001), prevalence of full-blown and partial PTSD (p=0.001), and other psychopathologic variables. Connective tissue disease and SF-36 were significantly associated with the TALS-SR scores in both univariate (p<0.001) and multivariate (p<0.025; p<0.001) analyses. CONCLUSIONS: Patients with SAD, and, in particular, patients with connective tissue diseases reported an increased risk of developing stress-related psychopathological symptoms, indicating the need for special psychological monitoring of this high-risk group.

Hyperinflammatory Coronavirus disease 2019 (COVID-19) and rapidly-progressive interstitial lung diseases (RP-ILD) secondary to inflammatory myopathies (IIM) present important similarities. These data support the use of anti-rheumatic drugs for the treatment of COVID-19. The aim of this study was to compare the efficacy of combining baricitinib and pulse steroids with the Standard of Care (SoC) for the treatment of critically ill COVID-19 patients. We retrospectively enrolled consecutive patients admitted to the Intensive Care Unit (ICU) with COVID-19-pneumonia. Patients treated with SoC (dexamethasone plus remdesivir) were compared to patients treated with baricitinib plus 6-methylprednisolone pulses (Rheuma-group). We enrolled 246 patients: 104/246 in the SoC and 142/246 in the Rheuma-group. All patients presented laboratory findings suggestive of hyperinflammatory response. Sixty-four patients (26.1%) died during ICU hospitalization. The mortality rate in the Rheuma-group was significantly lower than in the SoC-group (15.5 vs. 40.4%, p < 0.001). Compared to the SoC-group, patients in the Rheuma-group presented significantly lower inflammatory biomarker levels after one week of treatment. Higher ferritin levels after one week of treatment were strongly associated with mortality (p < 0.001). In this large real-life COVID-19 cohort, baricitinib and pulse steroids led to a significant reduction in mortality, paralleled by a prompt reduction in inflammatory biomarkers. Our experience supports the similarities between hyperinflammatory COVID-19 and the IIM-associated RP-ILD.

To detail the unmet clinical and scientific needs in the field of rheumatology. After a 2-year hiatus due to the SARS-CoV-2 pandemic, the 22nd annual international Advances in Targeted Therapies meeting brought together more than 100 leading basic scientists and clinical researchers in rheumatology, immunology, epidemiology, molecular biology and other specialties. Breakout sessions were convened with experts in five rheumatological disease-specific groups including: rheumatoid arthritis (RA), psoriatic arthritis, axial spondyloarthritis, systemic lupus erythematosus and connective tissue diseases (CTDs). In each group, experts were asked to identify and prioritise current unmet needs in clinical and translational research, as well as highlight recent progress in meeting formerly identified unmet needs. Clinical trial design innovation was emphasised across all disease states. Within RA, developing therapies and trials for refractory disease patients remained among the most important identified unmet needs and within lupus and spondyloarthritis the need to account for disease endotypes was highlighted. The RA group also identified the need to better understand the natural history of RA, pre-RA states and the need ultimately for precision medicine. In CTD generally, experts focused on the need to better identify molecular, cellular and clinical signals of early and undifferentiated disease in order to identify novel drug targets. There remains a strong need to develop therapies and therapeutic strategies for those with treatment-refractory disease. Increasingly it is clear that we need to better understand the natural history of these diseases, including their 'predisease' states, and identify molecular signatures, including at a tissue level, which can facilitate disease diagnosis and treatment. As these unmet needs in the field of rheumatic diseases have been identified based on consensus of expert clinicians and scientists in the field, this document may serve individual researchers, institutions and industry to help prioritise their scientific activities.
