RESUMEN
Adult-onset Still's disease (AOSD) is a rare inflammatory disease of unknown aetiology usually affecting young adults and manifesting with a clinical triad of spiking fever, arthritis, and evanescent cutaneous rash. AOSD may be considered a highly heterogeneous disease, despite a similar clinical presentation, the disease course may be completely different. Some patients may have a single episode of the disease whereas others may evolve toward a chronic course and experience life-threatening complications. On these bases, to dissect the clinical heterogeneity of this disease, four different subsets were identified combining the manifestations at the beginning with possible diverse outcomes over time. Each one of these derived subsets would be characterised by a prominent different clinical feature from others, thus proposing dissimilar underlying pathogenic mechanisms, at least partially. Consequently, a distinct management of AOSD may be suggested to appropriately tailor the therapeutic strategy to these patients, according to principles of the precision medicine. These findings would also provide the rationale to recognise a different genetic and molecular profile of patients with AOSD. Taking together these findings, the basis for a precision medicine approach may be suggested in AOSD, which would drive a tailored therapeutic approach in these patients. A better patient stratification may also help in arranging specific designed studies to improve the management of patients with AOSD. Behind these different clinical phenotypes, distinct endotypes of AOSD may be suggested, probably differing in pathogenesis, outcomes, and response to therapies.

OBJECTIVE: To evaluate the short-term effectiveness of guselkumab in patients with psoriatic arthritis (PsA) and suggestive features of axial involvement in a prospective "real-life" multicentre cohort. METHODS: Between June 2022 and June 2023, PsA patients with axial involvement were evaluated if treated at least for 4 months with guselkumab. The effectiveness was evaluated by BASDAI, ASDAS, DAPSA, and achievement of BASDAI ≤ 4, also exploiting predictive factors. In a group of patients, MRI findings on sacroiliac joints were assessed before and after guselkumab administration. RESULTS: Sixty-seven patients with PsA and suggestive features of axial involvement (age 53.4 ± 11.2 years, male sex 26.9%) were treated with guselkumab. After 4 months, a significant reduction of BASDAI, ASDAS, and DAPSA was observed. A ΔBASDAI of -2.11 ± 0.43 was estimated assessing the mean difference values before and after guselkumab administration and 52.2% of patients reached a BASDAI ≤ 4. In 27 patients, MRI findings on sacroiliac joints were assessed before and after guselkumab administration. A reduction of 0.80 or larger of the sacroiliac joint lesion score was observed in the majority of patients (70.3%) based on MRI improvements, paralleling with the clinical response.No life-threatening side effects were recorded; 17.9% of patients reported minor adverse events mainly injection site reactions. CONCLUSIONS: The short-term effectiveness of guselkumab in patients with PsA and suggestive features of axial involvement was shown. Although further studies are needed, our multicentre "real-life" study may suggest the clinical usability of guselkumab in this context.
RESUMEN
OBJECTIVES: Bosentan is a dual endothelin receptor antagonist approved for the treatment of SSc digital ulcers (DU) and pulmonary arterial hypertension (PAH). Systolic pulmonary arterial pressure (sPAP) is a relevant parameter for the follow-up and prognosis of SSc-PAH. The therapeutic magnitude of bosentan in SSc-PAH is not fully understood, thus we aim to establish the degree of sPAP reduction in bosentan treated SSc-PAH patients. METHODS: We performed a systematic literature review in three databases from January 2000 to June 2023, involving sPAP measurement at transthoracic echocardiography of SSc patients before and after starting bosentan. Following the study quality assessment and data extraction, we performed random-effects meta-analysis and Egger's test for publication bias. Stratified analysis was performed for mono-/combination therapy, follow up duration (≤1 year), indication for bosentan therapy (PAH or DU/mixed). RESULTS: In the 11 selected manuscripts, sPAP mean difference before and after bosentan therapy was - 5.63mmHg (CI95% -9.79 to -1.48, p=0.0078). In stratified analysis, sPAP mean was significantly different before and after bosentan therapy only for studies considering < 1 year of follow-up (p=0.0020), monotherapy (p=0.0140) and the strict indication for PAH (p=0.0002). CONCLUSIONS: Bosentan significantly decreases sPAP, a relevant prognostic marker, especially in overt SSc-PAH. However, bosentan did not decrease sPAP when started for DU/mixed indication nor for follow-up>1 year. The burden of publication bias was significant. Therefore, further studies are required to assess bosentan's haemodynamic effect in high-risk patients for SSc-PAH.

OBJECTIVES: We aimed to evaluate the drug retention rate (DRR) of secukinumab, an anti-IL-17A monoclonal antibody, in patients with psoriatic arthritis (PsA) in a real-life cohort, and to assess the impact of comorbidities and patient clinical characteristics on the DRR of secukinumab. METHODS: A retrospective study of prospective followed-up patients was performed to evaluate the DRR of secukinumab on patients with PsA attending the recruiting centres between January 2016 and June 2022. RESULTS: In 207 patients with PsA, a 60-month DRR of secukinumab of 57.0% was estimated (mean time of administration of 21.5±17.1 months). Male gender, age ≥65 years, disease duration ≥5 years and ≥10 years did not influence the DRR of secukinumab. The presence of comorbidities, considering any concomitant disorder, did not affect the DRR of secukinumab. In patients with cardiometabolic multimorbidity, a trend toward a better DRR of secukinumab was recorded. In fact, patients with high blood pressure, dyslipidaemia, and type 2 diabetes showed a trend toward an improved DRR of secukinumab. Furthermore, the presence of obesity did not influence the DRR of secukinumab. Different dosages, previous bDMARDs, and concomitant therapy with csDMARDs did not influence the DRR of secukinumab. CONCLUSIONS: A cumulative 60-month DRR of secukinumab of 57.0% in patients with PsA was retrieved. The presence of cardiometabolic multimorbidity could be associated with an improved DRR of secukinumab, whereas obesity did not affect this feature in our cohort. Previous bDMARDs, concomitant csDMARDs, and different drug dosages could not influence the DRR of secukinumab over time.

OBJECTIVES: Conflicting results about clinical and subclinical atherosclerosis in systemic sclerosis (SSc) and the associated risk factors have been reported. Hence, we aimed to determine the prevalence of clinical and subclinical atherosclerosis in a large number of Italian SSc patients and the associated risk factors. METHODS: This study included 613 SSc patients from 11 Italian tertiary Rheumatologic Units. All patients underwent full history taking, clinical examination, and relevant laboratory and radiological investigations. Doppler ultrasonography (US) of the common carotid and upper and lower limbs was performed to measure carotid and femoral intima-media thickness (cIMT and fIMT), and carotid and peripheral atheroma plaques. Doppler US of the brachial artery was performed to measure flow-mediated dilatation (FMD). RESULTS: Patients were mostly women (91.4%) with a median age of 61 years (range, 20-100); a median disease duration of 14 years (range, 0-77) from the onset of the first non-Raynaud's phenomenon (RP); 9.3% had a history of clinical atherosclerosis (9 stable/unstable angina, 21 myocardial infarctions, 24 heart failure, 3 strokes, 8 transient ischaemic attack, 6 intermittent claudication, 10 atrial thrombo-embolism). In 37.1% of patients, subclinical atherosclerosis was detected, after excluding those with a history of clinical atherosclerosis. The prevalence of clinical and subclinical atherosclerosis was higher than that reported by the European Society of Cardiology and observational studies that enrolled Italian healthy individuals as a control group, respectively. CONCLUSIONS: A higher prevalence of clinical and subclinical atherosclerosis was detected in SSc Italian patients and correlated with traditional and SSc-related risk factors.

Anti-fibroblast antibodies (AFA) have been reported in systemic sclerosis (SSc) and are known to promote fibroblast activation. Aim of this study was to characterize the fine specificity of AFA and to analyze any correlations with clinical parameters associated to fibrosis. To this end, AFA were affinity-purified from a patient with diffuse cutaneous SSc (dcSSc) and interstitial lung disease (ILD). Panning of a phage display peptide library with purified AFA identified the motif

Anti-centromere (ACA) and antimitochondrial antibodies (AMA) are specific for limited-cutaneous systemic sclerosis (lcSSc) and primary biliary cholangitis (PBC), respectively, and can coexist in up to 25 and 30% of SSc and PBC patients. Here, we evaluated whether anti-centromeric protein A (CENP-A) antibodies cross-react with mitochondrial antigens. To this end, sera from two lcSSc patients (pt1 and pt4), one of them (pt4) also affected by PBC, were used as the source of ACA, previously shown to recognize different groups of amino acids (motifs) in the CENP-A region spanning amino acids 1-17 (Ap1-17). Pt1 and pt4 Ap1-17-specific IgG were purified by affinity-chromatography on insolubilized Ap1-17-peptide column and tested by western blotting with nuclear and cytoplasmic protein extract from HeLa cells. Immunoreactive proteins were identified by mass spectrometry and validated by immunodot. The results showed that affinity-purified SSc/PBC pt4 anti-Ap1-17 and not SSc pt1 anti-Ap1-17 Ab, specifically cross-reacted with the E2 component of the mitochondrial pyruvate dehydrogenase complex (PDC-E2), the major mitochondrial autoantigen in PBC. Sequence homology analysis indicated that the motif A-x-x-P-x-A-P recognized by pt4 anti-Ap1-17 IgG and shared by CENP-A and PDC-E2, is also expressed by some members of the Human Herpesvirus family, suggesting that they may trigger the production of these cross-reacting antibodies.

OBJECTIVES: Interleukin (IL) 17s cytokines are key drivers of inflammation that are functionally dysregulated in several human immune-mediated inflammatory diseases (IMIDs), such as rheumatoid arthritis (RA), psoriasis and inflammatory bowel disease (IBD). Targeting these cytokines has some therapeutic benefits, but issues associated with low therapeutic efficacy and immunogenicity for subgroups of patients or IMIDs reduce their clinical use. Therefore, there is an urgent need to improve the coverage and efficacy of antibodies targeting IL-17A and/or IL-17F and IL-17A/F heterodimer. METHODS AND RESULTS: Here, we initially identified a bioactive 20 amino acid IL-17A/F-derived peptide (nIL-17) that mimics the pro-inflammatory actions of the full-length proteins. Subsequently, we generated a novel anti-IL-17 neutralising monoclonal antibody (Ab-IPL-IL-17) capable of effectively reversing the pro-inflammatory, pro-migratory actions of both nIL-17 and IL-17A/F. Importantly, we demonstrated that Ab-IPL-IL-17 has less off-target effects than the current gold-standard biologic, secukinumab. Finally, we compared the therapeutic efficacy of Ab-IPL-IL-17 with reference anti-IL-17 antibodies in preclinical murine models and samples from patients with RA and IBD. We found that Ab-IPL-IL-17 could effectively reduce clinical signs of arthritis and neutralise elevated IL-17 levels in IBD patient serum. CONCLUSIONS: Collectively, our preclinical and in vitro clinical evidence indicates high efficacy and therapeutic potency of Ab-IPL-IL-17, supporting the rationale for large-scale clinical evaluation of Ab-IPL-IL-17 in patients with IMIDs.

OBJECTIVES: CD248 is a glycoprotein, highly expressed on pericytes and fibroblasts (FBs), that is implicated in the fibrotic process. During angiogenesis, CD248 can promote vessel regression, binding multimerin-2 (MMRN-2). Thus, we investigated the expression of MMRN-2 in systemic sclerosis (SSc)-skin and of CD248 in isolated SSc-FBs. The anti-angiogenic property of CD248+ SSc-FBs was evaluated by co-culturing these cells with healthy control endothelial cells (HC-ECs). The apoptotic effect of CD248 on HC-ECs was evaluated. Finally, the ability of CD248 to prevent activation of VEGF receptor 2 (VEGFR2) was assessed. METHODS: By IF, MMRN-2 was investigated in SSc-skin and CD248 in SSc FBs. The anti-angiogenic property of CD248+ SSc-FBs was evaluated by HC-ECs/SSc-FBs co-cultures. Lentiviral-induced CD248 short-hairpin RNA delivery was employed for loss-of-function studies in SSc-FBs. HC-ECs were cultured in the presence of CD248 to assess apoptosis by IF and VEGFR2 phosphorylation by western blot. RESULTS: MMRN-2 expression was increased in skin SSc-ECs, whereas CD248 expression was increased in SSc-FBs. Functionally, CD248+-SSc-FBs suppressed angiogenesis in the organotypic model, as assessed by the reduction in total tube length of HC-ECs. This anti-angiogenetic behaviour was reversed by CD248 silencing. Furthermore, the presence of CD248 promoted the apoptosis of HC-ECs. Finally, CD248 prevented activation of VEGFR2 by reducing its phosphorylation after VEGF stimulation. CONCLUSION: CD248 was anti-angiogenic in vitro due to a reduction in tube formation and to induction of apoptosis of ECs. Increased expression of CD248 in SSc could contribute to the microvascular rarefaction observed at the tissue level in SSc. Our results suggest a pathogenic role for CD248-MMRN-2 in SSc.

OBJECTIVES: The coronavirus disease 19 (COVID-19) pandemic concerns the field of rheumatology in many ways. Arthritis in conjunction with COVID-19 is increasingly reported. However, clinical data are still limited and there is lack of a detailed characterisation of COVID-19 associated arthritis by musculoskeletal ultrasound (MSUS). This case series reports different forms of COVID-19 associated arthritis supported by MSUS in patients with or without underlying rheumatic and musculoskeletal disease (RMD). METHODS: From March 2020 to July 2021, adult patients (n=10) with arthritis timely related to COVID-19 were assessed in three European centres by clinical and laboratory values and additionally MSUS. RESULTS: In the group without underlying RMD (n=6), two patients presented with polyarticular arthralgia during severe COVID-19, swelling was rarely seen and MSUS demonstrated arthritis only in a few joints affected. The other four patients showed arthritis four to 16 weeks after mild or moderate COVID-19 (without hospitalisation): polyarthritis (n=1), oligoarthritis of the upper and lower limb (n=2), and in one case, late-onset rheumatoid arthritis (LORA) was newly diagnosed. In the group with an underlying RMD (n=4), an increase of disease activity was reported by MSUS during mild and mild-moderate COVID-19. In general, MSUS often presented power Doppler (PD) positive synovitis and tenosynovitis. CONCLUSIONS: In our patients without underlying RMD, arthritides associated with COVID-19 are comparable to the clinical picture of a reactive arthritis (ReA) or other virus-related arthritides (e.g. parvovirus B19). New onset or flares of RMD possibly triggered by COVID-19 are noteworthy.

OBJECTIVES: Due to the prevalence of fibromyalgia in psoriatic arthritis (PsA) patients, any evaluation about PsA-specific patient-reported outcomes (PROs) should take in account the possible bias related to this comorbidity. Patient acceptable symptom state (PASS) is a patient-reported measure evaluating the acceptable and/or satisfactory level of symptoms in rheumatic diseases, which has been proposed as a disease activity index, in patients with PsA. Thus, this study was designed to analyse if the association between PASS and PsA disease activity may be biased by the presence of comorbid fibromyalgia. METHODS: A multi-centre, cross-sectional, observational study enrolling consecutive PsA participants has been conducted from July 2021 to November 2021. The Disease Activity for Psoriatic Arthritis (DAPSA) was collected; the following formulation of PASS question: 'Think about all the ways your PsA has affected you during the last 48 hours. If you were to remain in the next few months as you were during the last 48 hours, would this be acceptable to you?', was submitted to our participants. RESULTS: Multivariable logistic regressions, adjusted for the presence of fibromyalgia, did not show any significant association between PASS and DAPSA low disease activity, DAPSA as nominal variable (remission, low disease activity, moderate disease activity, high disease activity) and DAPSA as continuous variable. CONCLUSIONS: Our data suggest that fibromyalgia influences the patient's perception of the disease and has a negative impact on PASS status independently of disease activity, thus limiting the utility of this Patient reported outcome in real world clinical practice.
RESUMEN
OBJECTIVES: The revised Fibromyalgia Impact Questionnaire (FIQR) is a widely used fibromyalgia severity assessment tool that was introduced in 2009 prior to the publication of the American College of Rheumatology (ACR) preliminary fibromyalgia criteria in 2010 and its revision in 2016. In 2020, the modified Fibromyalgia Assessment Scale (FASmod) was published. The Polysymptomatic Distress scale (PSD) of the fibromyalgia criteria and FASmod include assessments of pain location severity and can be used for diagnosis as well as in non-fibromyalgia patients. The aim of this study is to provide equations for the conversion of the FIQR scores to PSD and FASmod as an aid to understanding and sharing fibromyalgia severity information. METHODS: 3089 patients with fibromyalgia, diagnosed according to the ACR 2010/2011 criteria and belonging to the Italian Fibromyalgia Registry completed FIQR, FASmod and PSD questionnaires. Pearson's correlation coefficient was used to test the correlations between indices. The least square regression approach was used to produce predictive equations for each scale based on the remaining scales. RESULTS: FIQR was correlated with PSD (r=0.714) and FASmod (r=0.801); PSD and FASmod showed the highest correlation (r=0.897), expected since they assess the same constructs. Predictive equations showing a linear model were effective in producing mean cohort values, but individual predictions deviated substantially, precluding prediction in the individual patient. CONCLUSIONS: Conversion equations that allow for interconversion of multiple scales fibromyalgia severity assessment scales are produced. These can be useful in obtaining mean values for cohorts but are not accurate enough for use in individual patients.

OBJECTIVES: Primary Sjögren's syndrome (pSS) is frequently associated with autoimmune thyroiditis (AT). The aim of this study was to evaluate the prevalence of AT in a national cohort of pSS and to describe the clinical and histological phenotype of patients with pSS and associated AT. METHODS: In this multicentre cross-sectional study, data from 2546 pSS were collected and the presence of AT was reported. In a subgroup, the histology of minor salivary glands was evaluated. Differences between pSS with and without AT were evaluated. RESULTS: A concomitant pSS and AT was detected in 19.6% of cases. Patients with pSS and AT displayed a lower prevalence of lymphoma, male sex and disease-modifying anti-rheumatic drugs (DMARDs) use and a higher prevalence of fibromyalgia, coeliac disease and hypergammaglobulinaemia. Multivariable analysis confirmed a higher prevalence of fibromyalgia and coeliac disease and lower use of DMARDs. In a subgroup of patients (n=232), a significantly higher focus score and number of foci was detected in pSS without AT (n=169) as compared to pSS with AT (n=54). CONCLUSIONS: This is the largest study evaluating the coexistence of pSS and AT. We confirm a high association between pSS and AT and describe the presence of a different phenotype characterized by a higher rate of celiac disease and fibromyalgia. Although not significant, the lower prevalence of both lymphoma and intake of DMARDs, along with a significantly lower focus score and number of foci, possibly suggest a more favourable outcome in concomitant pSS and AT which further deserve future investigations.

OBJECTIVES: Psychosocial factors are recognised as important determinants of pain experience in patients with inflammatory arthritides. Among them, pain catastrophising, a maladaptive cognitive style, observed in patients with anxiety and depressive disorders, garnered specific attention. Here, we evaluated pain catastrophising (PC) and its related domains (Rumination, Magnification, and Helplessness), in psoriatic arthritis (PsA) and axial spondyloarhtiritis (axSpA) participants, to assess its impact on disease activity. Furthermore, we analysed possible correlations of PC-Scale (PCS) with those psychometric domains which have been already related to catastrophisation in patients with chronic pain. Lastly, we aimed to define the relationship between PCS and the different variables included in the composite indices of disease activity. METHODS: A multi-centre, cross-sectional, observational study has been conducted on 135 PsA (age 56 (47-64) years, males/females 40.74/59.26%; Disease Activity in Psoriasic Arthritis (DAPSA) 13.34 (5.21-22.22)) and 71 axSpA (age 49 (37-58) years, males/females 56.34/43.66%; Bath Ankylosing Spondylitis Arthritis Activity (BASDAI) 4.17 (2.1-6.3)) participants. Multivariable regressions and correlations were performed to evaluate the relationship between pain catastrophising and both disease activity and patient-reported outcomes. RESULTS: The adjusted linear regression model showed a positive association between PCS and DAPSA as well as between PCS and BASDAI; PCS negative impacts on the subjective domains of disease activity scores. CONCLUSIONS: This study suggests the role of PC, independently of inflammation, in disease perception and achievement of remission or low disease activity in chronic arthritides.

OBJECTIVES: To determine the cut-off values of Patient Acceptable Symptom State (PASS) for the revised Fibromyalgia Impact Questionnaire (FIQR), the modified Fibromyalgia Assessment Scale (FASmod), and the Polysymptomatic Distress scale (PSD) and to determine the predictors of PASS in patients with fibromyalgia (FM). METHODS: FM patients belonging to the Italian Fibromyalgia Registry (IFR) completed the FIQR, the FASmod and the PSD. The PASS was assessed using a dichotomous answer. The cut-off values were obtained through the receiver operating characteristic curve (ROC) analyses. A multivariate logistic regression analysis was performed to determine predictors of achieving the PASS. RESULTS: 5545 women (93.7%) and 369 males (6.3%) were included in the study. The 27.8% of patients reported an acceptable symptom state. Patients in PASS differed in all patient-reported outcome measures (p <0.001). The FIQR PASS threshold was ≤58 (area under the ROC curve [AUC] = 0.819). The FASmod PASS threshold was ≤23 (AUC = 0.805) and the PSD PASS threshold was ≤16 (AUC = 0.773). In the pairwise AUC comparison, the discriminatory power of the FIQR PASS outperforms both FASmod PASS (p = 0.0124) and PSD PASS (p <0.0001). Multivariate logistic analysis showed that FIQR items related to memory and pain were the only predictors of PASS. CONCLUSIONS: The FIQR, FASmod, and PSD PASS cut-off points for FM patients have never been determined before. This study provides additional information to facilitate interpretation of the severity assessment scales in daily practice and clinical research related to FM patients.

OBJECTIVES: To analyse how the potential exposure to air pollutants can influence the key components at the time of diagnosis of Sjögren's phenotype (epidemiological profile, sicca symptoms, and systemic disease). METHODS: For the present study, the following variables were selected for harmonization and refinement: age, sex, country, fulfilment of 2002/2016 criteria items, dry eyes, dry mouth, and overall ESSDAI score. Air pollution indexes per country were defined according to the OECD (1990-2021), including emission data of nitrogen and sulphur oxides (NO/SO), particulate matter (PM2.5 and 1.0), carbon monoxide (CO) and volatile organic compounds (VOC) calculated per unit of GDP, Kg per 1000 USD. RESULTS: The results of the chi-square tests of independence for each air pollutant with the frequency of dry eyes at diagnosis showed that, except for one, all variables exhibited p-values <0.0001. The most pronounced disparities emerged in the dry eye prevalence among individuals inhabiting countries with the highest NO/SO exposure, a surge of 4.61 percentage points compared to other countries, followed by CO (3.59 points), non-methane (3.32 points), PM2.5 (3.30 points), and PM1.0 (1.60 points) exposures. Concerning dry mouth, individuals residing in countries with worse NO/SO exposures exhibited a heightened frequency of dry mouth by 2.05 percentage points (p<0.0001), followed by non-methane exposure (1.21 percentage points increase, p=0.007). Individuals inhabiting countries with the worst NO/SO, CO, and PM2.5 pollution levels had a higher mean global ESSDAI score than those in lower-risk nations (all p-values <0.0001). When systemic disease was stratified according to DAS into low, moderate, and high systemic activity levels, a heightened proportion of individuals manifesting moderate/severe systemic activity was observed in countries with worse exposures to NO/SO, CO, and PM2.5 pollutant levels. CONCLUSIONS: For the first time, we suggest that pollution levels could influence how SjD appears at diagnosis in a large international cohort of patients. The most notable relationships were found between symptoms (dryness and general body symptoms) and NO/SO, CO, and PM2.5 levels.

OBJECTIVES: To analyse how the key components at the time of diagnosis of the Sjögren's phenotype (epidemiological profile, sicca symptoms, and systemic disease) can be influenced by the potential exposure to climate-related natural hazards. METHODS: For the present study, the following variables were selected for harmonisation and refinement: age, sex, country, fulfilment of 2002/2016 criteria items, dry eyes, dry mouth, and overall ESSDAI score. Climate-related hazards per country were defined according to the OECD and included seven climate-related hazard types: extreme temperature, extreme precipitation, drought, wildfire, wind threats, river flooding, and coastal flooding. Climatic variables were defined as dichotomous variables according to whether each country is ranked among the ten countries with the most significant exposure. RESULTS: After applying data-cleaning techniques and excluding people from countries not included in the OECD climate rankings, the database study analysed 16,042 patients from 23 countries. The disease was diagnosed between 1 and 3 years earlier in people living in countries included among the top 10 worst exposed to extreme precipitation, wildfire, wind threats, river flooding, and coastal flooding. A lower frequency of dry eyes was observed in people living in countries exposed to wind threats, river flooding, and coastal flooding, with a level of statistical association being classified as strong (p<0.0001 for the three variables). The frequency of dry mouth was significantly lower in people living in countries exposed to river flooding (p<0.0001) and coastal flooding (p<0.0001). People living in countries included in the worse climate scenarios for extreme temperature (p<0.0001) and river flooding (p<0.0001) showed a higher mean ESSDAI score in comparison with people living in no-risk countries. In contrast, those living in countries exposed to worse climate scenarios for wind threats (p<0.0001) and coastal flooding (p<0.0001) showed a lower mean ESSDAI score in comparison with people living in no-risk countries. CONCLUSIONS: Local exposure to extreme climate-related hazards plays a role in modulating the presentation of Sjögren across countries concerning the age at which the disease is diagnosed, the frequency of dryness, and the degree of systemic activity.

To assess stimulator of interferon genes (STING) pathway in patients with adult-onset Still's disease (AOSD) who were complicated or not by macrophage activation syndrome (MAS), evaluating peripheral blood mononuclear cells (PBMCs), and synovial tissues. The relative mRNA expression of key molecules of the STING pathway (i.e. CGAS, NLRP4, PKDC, STING1, XRCC5, and XRCC6) and interferon (IFN)-γ was assessed in PBMCs obtained from patients with AOSD, who were complicated or not by MAS, and healthy controls (HCs). A bulky RNA sequencing was performed in synovial tissues from two patients with AOSD. Finally, the ability of heavy ferritin subunit (FeH) to induce the expression of NLRP4 was evaluated in cultured macrophages. Twenty patients with AOSD were analysed. Out of them, seven patients were complicated by MAS. Assessing mRNA relative expression in PBMCs, STING1, NLRP4, XRCC6, and IFN-γ were significantly expressed in AOSD than HCs. The mRNA relative expression of CGAS, PKDC, and XRCC5 did not differ between patients and HCs. Furthermore, NLRP4 and IFN-γ resulted to be significantly increased in patients with AOSD complicated by MAS than others. By RNA-sequencing analysis, we observed that Nlrp4 gene was significantly up-regulated in patients with AOSD. Following the stimulation with FeH, an increased expression of NLRP4 was observed in cultured macrophages. In conclusion, an increased expression of some key molecules of STING pathway characterized patients with AOSD. In addition, our results suggested that a hyper-activity of NLRP4 may be observed in patients with MAS. Furthermore, FeH increased the expression of NLRP4 in cultured macrophages.

OBJECTIVES: To update the EULAR points to consider (PtCs) on the use of immunomodulatory therapies in COVID-19. METHODS: According to the EULAR standardised operating procedures, a systematic literature review up to 14 July 2021 was conducted and followed by a consensus meeting of an international multidisciplinary task force. The new statements were consolidated by formal voting. RESULTS: We updated 2 overarching principles and 12 PtC. Evidence was only available in moderate to severe and critical patients. Glucocorticoids alone or in combination with tocilizumab are beneficial in COVID-19 cases requiring oxygen therapy and in critical COVID-19. Use of Janus kinase inhibitors (baricitinib and tofacitinib) is promising in the same populations of severe and critical COVID-19. Anti-SARS-CoV-2 monoclonal antibodies and convalescent plasma may find application in early phases of the disease and in selected subgroups of immunosuppressed patients. There was insufficient robust evidence for the efficacy of other immunomodulators with further work being needed in relation to biomarker-based stratification for IL-1 therapy CONCLUSIONS: Growing evidence supports incremental efficacy of glucocorticoids alone or combined with tocilizumab/Janus kinase inhibitors in moderate to severe and critical COVID-19. Ongoing studies may unmask the potential application of other therapeutic approaches. Involvement of rheumatologists, as systemic inflammatory diseases experts, should be encouraged in clinical trials of immunomodulatory therapy in COVID-19.

Autoimmune systemic diseases (ASD) show impaired immunogenicity to COVID-19 vaccines. Our prospective observational multicenter study aimed at evaluating the seroconversion elicited by COVID-19 vaccine over the entire vaccination cycle including the booster dose. Among 478 unselected ASD patients originally evaluated at the end of the first vaccination cycle (time 1), 344 individuals were re-evaluated after a 6-month period (time 2), and 244 after the booster vaccine dose (time 3). The immunogenicity of mRNA COVID-19 vaccines (BNT162b2 and mRNA-1273) was assessed by measuring serum IgG-neutralizing antibody (NAb) on samples obtained at the three time points in both patients and 502 age-matched controls. In the 244 ASD group that received booster vaccine and monitored over the entire follow-up, the mean serum NAb levels (time 1, 2, and 3: 696.8 ± 52.68, 370.8 ± 41.92, and 1527 ± 74.16SD BAU/mL, respectively; p < 0.0001) were constantly lower compared to controls (p < 0.0001), but they significantly increased after the booster dose compared to the first two measurements (p < 0.0001). The percentage of patients with absent/suboptimal response to vaccine significantly decreased after the booster dose compared to the first and second evaluations (time 1, 2, and 3: from 28.2% to 46.3%, and to 7.8%, respectively; p < 0.0001). Of note, the percentage of patients with absent/suboptimal response after the booster dose was significantly higher compared to controls (19/244, 7.8% vs 1/502, 0.2%; p < 0.0001). Similarly, treatment with immune-modifiers increased the percentage of patients exhibiting absent/suboptimal response (16/122, 13.1% vs 3/122, 2.46%; p = 0.0031). Overall, the above findings indicate the usefulness of booster vaccine administration in ASD patients. Moreover, the persistence of a significantly higher percentage of individuals without effective seroconversion (7.8%), even after the booster dose, warrants for careful monitoring of NAb levels in all ASD patients to identify those with increased risk of infection. In this particularly frail patients' setting, tailored vaccination and/or therapeutic strategy are highly advisable.
