The Systemic Lupus International Collaborating Clinics (SLICC), American College of Rheumatology (ACR), and the Lupus Foundation of America are developing a revised systemic lupus erythematosus (SLE) damage index (the SLICC/ACR Damage Index [SDI]). Shifts in the concept of damage in SLE have occurred with new insights into disease manifestations, diagnostics, and therapy. We evaluated contemporary constructs in SLE damage to inform development of the revised SDI.We conducted a 3-part qualitative study of international SLE experts. Facilitated small groups evaluated the construct underlying the concept of damage in SLE. A consensus meeting using nominal group technique was conducted to achieve agreement on aspects of the conceptual framework and scope of the revised damage index. The framework was finally reviewed and agreed upon by the entire group.Fifty participants from 13 countries were included. The 8 thematic clusters underlying the construct of SLE damage were purpose, items, weighting, reversibility, impact, time frame, attribution, and perspective. The revised SDI will be a discriminative index to measure morbidity in SLE, independent of activity or impact on the patient, and should be related to mortality. The SDI is primarily intended for research purposes and should take a life-course approach. Damage can occur before a diagnosis of SLE but should be attributable to SLE. Damage to an organ is irreversible, but the functional consequences on that organ may improve over time through physiological adaptation or treatment.We identified shifts in the paradigm of SLE damage and developed a unifying conceptual framework. These data form the groundwork for the next phases of SDI development.

Background: Systemic lupus erythematosus (SLE) is associated with clinical burden for the patient and organ damage. The development of therapies for SLE has been constrained by clinical and biologic heterogeneity. These represent challenges in clinical trial design and endpoint selection. Objective: To identify the most relevant descriptors for efficacy, endpoints, disease activity, organ damage, quality of life (QoL), and Patient Reported Outcome Measures (PROMs) in the treatment of SLE. Methods: A Delphi study was conducted using a national expert panel of clinicians in the treatment of SLE. A steering committee composed of 3 opinion leaders with deep expertise in SLE treatment was defined. The steering committee analyzed and appraised the evidence, designed the Delphi study, defined the statements, and analyzed the expert panel responses. A 2-round Delphi survey was conducted. Participants were asked to rate the statements using a five-point Likert scale. Results: Nine experts participated in the Delphi survey. After the two rounds, the consensus was reached on 18 of the 23 statements: 2 statements were included in the “efficacy” domain, 2 in the “glucocorticoid-sparing” domain, 2 in the “endpoint evaluation” domain, 4 in the “score” domain, 1 in the “disease activity” domain, 1 in the “organ damage” domain, 1 in the “QoL” domain, 2 in the “PROMs” domain, 1 in the “AIFA monitoring” domain and 2 in the “extra” domain. No statements reached consensus within the “onset” domain. Conclusion: In this Delphi study, 18 statements across 11 domains were agreed upon for the treatment of SLE.

Objective This study aims at evaluating the cost-of-illness (COI) of patients diagnosed with Behcet’s syndrome (BS) in Italy, trying to depict the impact of different costs’ components to the overall economic burden and analysing the variability of costs according to years since diagnosis and age at first symptoms. Methods With a cross-sectional evaluation, we surveyed a large sample of BS patients in Italy assessing several dimensions related to BS, also including fact related to the use of health resources utilization, formal and informal care, and productivity losses. Overall costs, direct health, direct non-health, and indirect costs were thus estimated per patient/year considering a Societal perspective and the impact of years since diagnosis, age at first symptoms on costs was evaluated using generalized linear model (GLM) and a two-part model, adjusting for age and distinguishing among employed and non-employed responders. Results A total of 207 patients were considered in the present study. From the perspective of the Society, mean overall costs for BS patient were estimated to be 21,624 € (0;193,617) per patient/year. Direct non-health expenses were the main costs component accounting for 58% of the overall costs, followed direct health costs, 36%, while indirect costs because of productivity losses represented 6% of the overall costs. Being employed resulted in significantly lower overall costs (p = 0.006). Results from the multivariate regression analyses suggested that the probability of incurring in overall costs equal to zero decreased as time from BS diagnosis is 1 year or more as compared to newly diagnosed patients (p p = 0.027) or later (p = 0.032) as compared to those having symptoms earlier. Similar findings emerged among the subgroups of patients declaring themselves as workers, while no impact of years since diagnosis or age of first symptoms was found among non-workers. Conclusions The present study offers a comprehensive overview of the economic consequences imposed by BS in a societal perspective, providing insights into the distribution of the different costs component related to BS, thus helping the development of targeted policies.

Calcification of Joints and Arteries (CALJA) is a rare disease that leads to chronic arthritis and lower limb claudication due to hydroxyapatite crystal deposition. The disease is caused by mutations in the 5-nucleotidase (NT5E) gene, which is responsible for pyrophosphate metabolism. Only 23 cases have been described so far. In this case report, we describe a new case of CALJA and provide a literature review. A 65-year-old woman was referred to the Rheumatology Unit with the diagnosis of seronegative oligo-arthritis. She complained of lower limb claudication, which was becoming progressively worse. Doppler ultrasound revealed bilateral obliteration of the popliteal and femoral arteries, and X-rays of the knees, hands, and feet showed extensive periarticular calcific deposits. The results of the NT5E gene analysis were positive for an inactivating variant, leading to the diagnosis of CALJA. The clinical features of CALJA are caused by hydroxyapatite crystal deposition at the periarticular and vascular levels due to abnormalities of pyrophosphate metabolism. Currently, no specific treatment is available, although a trial on the use of etidronate is ongoing. Patients with CALJA are often treated with immunosuppressant agents in the suspect of inflammatory rheumatologic diseases. Our case is the first in which clinical symptoms and a steady increase of inflammatory markers improved only after colchicine therapy initiation. It is crucial for the rheumatologist to recognize the features CALJA and keep it in mind in the differential diagnosis of patients with lower limb arterial insufficiency and arthritis or early osteoarthritis with joint calcification.

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.

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.

Objectives To evaluate the performance of oropharyngoesophageal scintigraphy (OPES) in the assessment of dysphagia in patients with systemic sclerosis (SSc), and to compare OPES results with those of barium esophagogram. Methods Adult SSc patients who underwent OPES for the assessment of dysphagia were enrolled. OPES was performed with both liquid and semisolid boluses and provided information regarding oropharyngeal transit time, esophageal transit time (ETT), oropharyngeal retention index (OPRI), esophageal retention index (ERI), and site of bolus retention. Barium esophagogram results were also collected. Results Fifty-seven SSc patients (87.7% female, mean age 57.7 years) with dysphagia were enrolled. OPES identified at least one alteration in each patient and findings were generally worse for the semisolid bolus. Esophageal motility was widely impaired with 89.5% of patients with an increased semisolid ERI, and middle-lower esophagus was the most frequent site of bolus retention. However, oropharyngeal impairment was highlighted by widespread increased OPRI, especially in anti-topoisomerase I positivity. Older patients and with longer disease duration presented slower semisolid ETT (p = 0.029 and p = 0.002, respectively). Eleven patients with dysphagia had a negative barium esophagogram: all of them presented some alterations in OPES parameters. Conclusion OPES revealed a marked SSc esophageal impairment, in terms of both slowed transit time and increased bolus retention, but also shed light on oropharyngeal swallowing alterations. OPES showed high sensitivity, being able to detect swallowing alterations in dysphagic patients with negative barium esophagogram. Therefore, the use of OPES for the assessment of SSc-related dysphagia in clinical practice should be promoted.

This case report describes 2 women with severe and refractory discoid lupus erythematosus that was treated with anifrolumab.

Autoimmune rheumatic diseases (ARD) can affect women and men during fertile age, therefore reproductive health is a priority issue in rheumatology. Many topics need to be considered during preconception counselling: fertility, the impact of disease-related factors on pregnancy outcomes, the influence of pregnancy on disease activity, the compatibility of medications with pregnancy and breastfeeding. Risk stratification and individualized treatment approach elaborated by a multidisciplinary team minimize the risk of adverse pregnancy outcomes (APO). Research has been focused on identifying biomarkers that can be predictive of APO. Specifically, preeclampsia and hypertensive disorders of pregnancy tend to develop more frequently in women with ARD. Placental insufficiency can lead to intrauterine growth restriction and small-for-gestational age newborns. Such APO have been shown to be associated with maternal disease activity in different ARD. Therefore, a key message to be addressed to the woman wishing for a pregnancy and to her family is that treatment with compatible drugs is the best way to ensure maternal and fetal wellbeing. An increasing number of medications have entered the management of ARD, but data about their use in pregnancy and lactation are scarce. More information is needed for most biologic drugs and their biosimilars, and for the so-called small molecules, while there is sufficient evidence to recommend the use of TNF inhibitors if needed for keeping maternal disease under control. Other issues related to the reproductive journey have emerged as "unmet needs", such as sexual dysfunction, contraception, medically assisted reproduction techniques, long-term outcome of children, and they will be addressed in this review paper. Collaborative research has been instrumental to reach current knowledge and the future will bring novel insights thanks to pregnancy registries and prospective studies that have been established in several Countries and to their joint efforts in merging data.

European Reference Networks; Rare and complex connective tissue diseases; Registries Redes Europeas de Referencia; Enfermedades raras y complejas del tejido conjuntivo; Registros Xarxes de referència europees; Malalties rares i complexes del teixit conjuntiu; Registres Background: Patient registries play a crucial role in supporting clinical practice, healthcare planning and medical research, offering a real-world picture on rare and complex connective tissue diseases (rCTDs). ERN ReCONNET launched the first European Registry Infrastructure with the aim to plan, upgrade and link registries for rCTDs, with the final goal to promote a harmonized data collection approach all over Europe for rCTDs. Methods: An online survey addressed to healthcare professionals and patients' representatives active in the field of rCTDs was integrated by an extensive database search in order to build a mapping of existing registries for rCTDs. Findings: A total of 140 registries were found, 38 of which include multiple diseases. No disease-specific registry was identified for relapsing polychondritis, mixed connective tissue disease and undifferentiated connective tissue disease. Discussion: This overview on the existing registries for rCTDs provides a useful starting point to identify the gaps and the strengths of registries on the coverage of rCTDs, and to develop a common data set and data collection approach for the establishment of the TogethERN ReCONNET Infrastructure. This work was funded by the European Union's Health Program (2014–2020). ERN ReCONNET is one of the 24 European Reference Networks (ERNs) approved by the ERN Board of Member States. The ERNs are co-funded by the EC (European Commission) (grant no. 947700).

ObjectiveThe aim of this work is to explore patient’ unmet needs of rare and complex rheumatic tissue diseases (rCTDs) patients during pregnancy and its planning by means of the narrative-based medicine (NBM) approach.MethodsA panel of nine rCTDs patients’ representatives was identified to codesign a survey aimed at collecting the stories of rCTD patients who had one or more pregnancies/miscarriages. The results of the survey and the stories collected were analysed and discussed with a panel of patients’ representatives to identify unmet needs, challenges and possible strategies to improve the care of rCTD patients.Results129 replies were collected, and 112 stories were analysed. Several unmet needs in the management of pregnancy in rCTDs were identified, such as fragmentation of care among different centres, lack of education and awareness on rCTD pregnancies among midwifes, obstetricians and gynaecologists. The lack of receiving appropriate information and education on rCTDs pregnancy was also highlighted by patients and their families. The need for a holistic approach and the availability specialised pregnancy clinics with a multidisciplinary organisation as well as the provision of psychological support during all the phases around pregnancy was considered also a priority.ConclusionThe adoption of the NBM approach enabled a direct identification of unmet needs, and a list of possible actions was elaborated to improve the care of rCTD patients and their families in future initiatives.

Sydenham’s chorea (SC) is a post-streptococcal autoimmune disorder of the central nervous system, and it is a major criterium for the diagnosis of acute rheumatic fever (ARF). SC typically improves in 12–15 weeks, but patients can be affected for years by persistence and recurrencies of both neurological and neuropsychiatric symptoms. We enrolled 48 patients with a previous diagnosis of ARF, with or without SC, in a national multicenter prospective study, to evaluate the presence of neuropsychiatric symptoms several years after SC’s onset. Our population was divided in a SC group (n = 21), consisting of patients who had SC, and a nSC group (n = 27), consisting of patients who had ARF without SC. Both groups were evaluated by the administration of 8 different neuropsychiatric tests. The Work and Social Adjustment Scale (WSAS) showed significantly (p = 0.021) higher alterations in the SC group than in the nSC group. Furthermore, 60.4% (n = 29) of the overall population experienced neuropsychiatric symptoms other than choreic movements at diagnosis and this finding was significantly more common (p = 0.00) in SC patients (95.2%) than in nSC patients (33.3%). The other neuropsychiatric tests also produced significant results, indicating that SC can exert a strong psychopathological impact on patients even years after its onset.

Mechanisms for the generation of anti-dsDNA autoantibodies are still not completely elucidated. One theory states that dsDNA interacts for mimicry with antibodies raised versus other antigens but molecular features for mimicry are unknown. Here we show that, at physiological acid-base balance, anti-Annexin A1 binds IgG2 dsDNA in a competitive and dose-dependent way with Annexin A1 and that the competition between the two molecules is null at pH 9. On the other hand, these findings also show that dsDNA and Annexin A1 interact with their respective antibodies on a strictly pH-dependent basis: in both cases, the binding was minimal at pH 4 and maximal at pH9-10. The anionic charge of dsDNA is mainly conferred by the numerous phosphatidic residues. The epitope binding site of Annexin A1 for anti-Annexin A1 IgG2 was here characterized as a string of 34 amino acids at the NH2 terminus, 10 of which are anionic. Circulating levels of anti-dsDNA and anti-Annexin A1 IgG2 antibodies were strongly correlated in patients with systemic lupus erythematosus (n 496) and lupus nephritis (n 425) stratified for age, sex, etc. These results show that dsDNA competes with Annexin A1 for the binding with anti-Annexin A1 IgG2 on a dose and charged mediated base, being able to display an inhibition up to 75%. This study provides the first demonstration that dsDNA may interact with antibodies raised versus other anionic molecules (anti-Annexin A1 IgG2) because of charge mimicry and this interaction may contribute to anti-dsDNA antibodies generation.

Here we describe the case of a 38-year-old man with a history of ischemic transient attacks and strokes from the age of 9 years, livedo reticularis, asymmetrical sensorimotor neuropathy, optic neuritis, testicular ischemia, digital ulcers, ulcerative colitis, and diastolic hypertension. Disease course was characterized by severe disease bouts treated with high-dose intravenous (IV) glucocorticoid (GC) pulse therapy, short periods of paucisymptomatic disease, and inability to taper GCs despite the use of traditional oral and IV immunosuppressants, interferon, and plasmapheresis.

Primary Sjögren's syndrome (pSS) is an autoimmune exocrinopathy classically presenting with sicca symptoms. Nonetheless, disease onset with extraglandular manifestations, including interstitial lung disease (ILD), is increasingly reported. However, studies investigating pSS patients presenting with ILD (pSS-ILD) are limited.Aim of this study was to better characterise the phenotype of pSS patients presenting with ILD in comparison to pSS patients with classicsicca-onset. We especially investigated whether the two groups differed in glandular involvement comparing functional, imaging andhistologic findings, as well as patient reported outcome (PRO).Consecutive newly diagnosed pSS patients, all fulfilling the ACR/EULAR 2016 criteria, were included in this cross-sectional study from September 2016 to October 2021. Presence of ILD at pSS diagnosis was defined based on clinical findings, imaging assessment and pulmonary function tests (PFT). In addition to functional tests, a minor salivary gland biopsy was performed in all cases, recording number of foci, focus score (FS) and GC-like structures. Salivary glands ultrasonography (SGUS) was graded using the OMERACT semiquantitative scoring system (0-3) based on parenchyma inhomogeneity. PRO including ESSPRI, OHIP and OSSDI were collected.Extraglandular clinical features and biological abnormalities included in the ESSDAI were recorded. Data were expressed as mean±SD for continuous variables and as absolute frequencies and percentages for categorical variables. Chi-Square test and Mann-Whitney U-test and ANOVA were performed for comparisons of categorical variables and continuous variables, respectively.We included 178 newly diagnosed pSS patients (F:M=158:20). ILD was the first pSS manifestation in 11 (6%) cases, 8 F and 3 M, with a median time from ILD onset to pSS diagnosis of 2 years (25-75 IQ 1-4.5). Of the 11 pSS-ILD patients, HRCT pattern was defined as NSIP in 4, UIP in 4, NSIP+OP in 2 and LIP in 1 patient. Dyspnoea on exertion or chronic cough were reported by 7/11 (63.6%) patients.In comparison to sicca-onset patients, pSS-ILD patients presented an older age at diagnosis (55±13 vs. 70±7, p= 0.001) and a higher ESSDAI (3.9±4.7 vs. 12.3±4.3, p=0.001), driven by the pulmonary domain. Regarding glandular involvement, pSS-ILD patients reported milder xeropthalmia (VAS 5.8±3.1 vs. 2.8±3.5, p=0.002) and significative lower scores in OSDI (35.6±24.9 vs. 15.3±22.9, p=0.04) and OHIP (4.8±4.4 vs. 1.4±3.8, p=0.04), despite no significant differences observed between the two groups in ocular tests and unstimulated salivary flow rate. With respect to histology, no significant differences were found in number of foci, FS and GC-like structures. We observed a significantly different distribution of the SGUS OMERACT score in the two groups: none of pSS-ILD patients presented a SGUS OMERACT score ≥2 in the submandibular glands (SG), in contrast to 41/132 (31.1%) of the patients in the classical sicca-onset group (p=0.03). Finally, no significant differences were observed between the two groups with respect to non-pulmonary extraglandular manifestations, serologic features and other biological parameters.ILD-onset pSS patients represent an atypical phenotypic subset, with less pronounced sialadenitis structural changes in salivary glands, and with sicca symptoms probably overshadowed by the respiratory disease.

Our study aims at providing evidence on patterns of use of biologic drugs for psoriasis in Tuscany, Italy. We conducted a drug-utilization study based on administrative databanks of Tuscany (EUPAS45365) from 2011 to 2019. We selected new users of etanercept, infliximab, adalimumab, ustekinumab, or secukinumab between 1 January 2011 and 31 December 2016. We considered subjects with psoriasis and followed subjects until the end of the study period (three years after the first dispensation of biologic drug for psoriasis) or the patient’s death, whichever came first. We censored subjects for pregnancy or neoplasia. For each subject, we defined the state as the weekly coverage of one of the biologic drugs of interest. We then defined the switch as the change from a state to another one. A total of 7062 subjects with a first dispensation of a PSObio drug in the inclusion period was identified, and 1839 (52.9% female, 51.6 mean age) patients were included in the analysis. Among new users of adalimumab (N = 770, 41.9%), one third showed a continuous behaviour whereas the others moved to etanercept and ustekinumab. New users of etanercept (N = 758, 41.2%), had the highest proportion of switchers, with adalimumab most often being the second choice. New users of infliximab (N = 159, 8.6%) experienced the highest proportion of treatment discontinuation. The present study suggests that the majority of patients treated with PSObio drugs do not switch from one active ingredient to another. However, patients who started biological therapy with etanercept had the highest frequency of switching to other PSObio drugs, whereas those who started with secukinumab or ustekinumab had the lowest.

The Physician Global Assessment International Standardisation COnsensus in Systemic Lupus Erythematosus (PISCOS) study aimed to obtain an evidence-based and expert-based consensus standardisation of the Physician Global Assessment (PGA) scoring of disease activity in systemic lupus erythematosus (SLE). An international panel of 79 SLE experts participated in a three-round Delphi consensus process, in which 41 statements related to the PGA in SLE were rated, using a 0 (strongly disagree) to 10 (strongly agree) numerical rating scale. Statements with agreement of 75% or greater were selected and further validated by the expert panel. Consensus was reached on 27 statements, grouped in 14 recommendations, for the use of the PGA in SLE, design of the PGA scale, practical considerations for PGA scoring, and the relationship between PGA values and levels of disease activity. Among these recommendations, the expert panel agreed that the PGA should consist of a 0–3 visual analogue scale for measuring disease activity in patients with SLE in the preceding month. The PGA is intended to rate the overall disease activity, taking into account the severity of active manifestations and clinical laboratory results, but excluding organ damage, serology, and subjective findings unrelated to disease activity. The PGA scale ranges from “no disease activity” (0) to the “most severe disease activity” (3) and incorporates the values 1 and 2 as inner markers to categorise disease activity as mild (≥0·5 to 1), moderate (>1 and ≤2) and severe (>2 to 3). Only experienced physicians can rate the PGA, and it should be preferably scored by the same rater at each visit. The PISCOS results will allow for increased homogeneity and reliability of PGA ratings in routine clinical practice, definitions of remission and low disease activity, and future SLE trials.

Treat-to-target is a therapeutic approach based on adjustments to treatment at set intervals in order to achieve well-defined, clinically relevant targets. This approach has been successfully applied to many chronic conditions, and in rheumatology promising results have emerged for rheumatoid arthritis. For systemic lupus erythematosus (SLE), defining the most meaningful treatment targets has been challenging, due to disease complexity and heterogeneity. Control of disease activity, the reduction of damage accrual and the patient’s quality of life should be considered as the main targets in SLE, and several new drugs are emerging to achieve these targets. This review is focused on describing the target to achieve in SLE and the methods to do so, and it is also aimed at discussing if treat-to-target could be a promising approach also for this complex disease.

Background: To assess skin involvement in a cohort of patients with systemic sclerosis (SSc) by comparing results obtained from modified Rodnan skin score (mRSS), durometry and ultra-high frequency ultrasound (UHFUS). Methods: SSc patients were enrolled along with healthy controls (HC), assessing disease-specific characteristics. Five regions of interest were investigated in the non-dominant upper limb. Each patient underwent a rheumatological evaluation of the mRSS, dermatological measurement with a durometer, and radiological UHFUS assessment with a 70 MHz probe calculating the mean grayscale value (MGV). Results: Forty-seven SSc patients (87.2% female, mean age 56.4 years) and 15 HC comparable for age and sex were enrolled. Durometry showed a positive correlation with mRSS in most regions of interest (p = 0.025, ρ = 0.34 in mean). When performing UHFUS, SSc patients had a significantly thicker epidermal layer (p < 0.001) and lower epidermal MGV (p = 0.01) than HC in almost all the different regions of interest. Lower values of dermal MGV were found at the distal and intermediate phalanx (p < 0.01). No relationships were found between UHFUS results either with mRSS or durometry. Conclusions: UHFUS is an emergent tool for skin assessment in SSc, showing significant alterations concerning skin thickness and echogenicity when compared with HC. The lack of correlations between UHFUS and both mRSS and durometry suggests that these are not equivalent techniques but may represent complementary methods for a full non-invasive skin evaluation in SSc.

Aim. To assess the efficacy of belimumab in joint and skin manifestations in a nationwide cohort of patients with SLE. Methods. All patients with skin and joint involvement enrolled in the BeRLiSS cohort were considered. Belimumab (intravenous, 10 mg/kg) effectiveness in joint and skin manifestations was assessed by DAS28 and CLASI, respectively. Attainment and predictors of DAS28 remission (

ObjectiveSystemic sclerosis (SSc) is burdened by Raynaud phenomenon (RP) and digital ulcers (DUs), and sometimes standard vasoactive therapies are ineffective or contraindicated. Selexipag is an oral selective IP prostacyclin receptor agonist approved for the treatment of SSc-related pulmonary arterial hypertension. We aimed to evaluate the clinical and instrumental efficacy of selexipag in SSc digital vasculopathy.MethodsPatients with SSc with severe digital vasculopathy refractory or with contraindication to all other vasoactive therapies were administered selexipag. RP- and DU-related clinical outcomes were evaluated, and digital perfusion was assessed by laser speckle contrast analysis (LASCA), all at baseline and after 3 months.ResultsSelexipag was administered to 9 patients with SSc (66.6% female, mean age 52.3 [SD 16.6] yrs). One patient had to stop the drug because of adverse effects. After 3 months of selexipag administration, there was a significant reduction in RP daily episodes (P= 0.01) and RP mean duration (P= 0.04). The number of DUs decreased from 10 to 4 without reaching statistical significance. A significant improvement in mean perfusion of the fingers (P= 0.02) was observed with LASCA.ConclusionSelexipag showed good potential for the treatment of SSc digital vasculopathy. Our results are certainly preliminary, yet quite encouraging. New trials for the evaluation of selexipag efficacy in SSc digital vasculopathy are needed.

BackgroundSLE is an autoimmune disease that predominantly affects women. As most epidemiological and interventional studies are on populations with a clear female prevalence, the influence of gender in disease course, drug response and damage accrual is yet to be fully explored and comprehended.ObjectivesTo describe gender differences in disease course, comorbidities, use of medications and long-term outcomes of a large cohort of patients with SLE.MethodsRetrospective gender-based analysis of prospectively collected data from a monocentric cohort of Caucasian patients with SLE with at least 1 year of follow-up.Results417 patients were included, 51 men and 366 women. Men displayed a significantly higher median age at disease onset and diagnosis and a higher prevalence of late-onset SLE, serositis at disease onset, antiphospholipid syndrome (APS) and use of mycophenolate within the first year of disease. Women had a higher prevalence of haematological abnormalities, a higher cumulative exposure to azathioprine and higher cumulative dose of glucocorticoids at 5 years. Male patients had a shorter time to first damage item and a higher prevalence of damage at 1 and 5 years, but this association was no longer significant when late-onset patients were excluded. No differences were found in prevalence of childhood onset, delay between onset and diagnosis, time to renal involvement and histology, cumulative autoantibody positivity, number of flares and hospitalisations, median SLE Damage Index score, type of damage, age and time to first cardiovascular event, chronic kidney disease and death.ConclusionsIn our cohort, clinical manifestations and disease course were similar in male and female patients; however, male patients displayed higher prevalence of APS and early damage accrual probably due to the later disease onset. These data highlight the importance of an intensive follow-up, prevention and treatment of complications in this category of patients, especially in the first years of disease.

Background Systemic Sclerosis (SSc) is a chronic autoimmune disease with a complex pathogenesis that includes vascular injury, abnormal immune activation, and tissue fibrosis. We provided a complete epidemiological characterization of SSc in the Tuscany region (Italy), considering prevalence and incidence, survival, comorbidities and drug prescriptions, by using a multi-database population-based approach. Cases of SSc diagnosed between 1st January 2003 and 31st December 2017 among residents in Tuscany were collected from the population-based Rare Diseases Registry of Tuscany. All cases were linked to regional health and demographic databases to obtain information about vital statistics, principal causes of hospitalization, complications and comorbidities, and drug prescriptions. Results The prevalence of SSc in Tuscany population resulted to be 22.2 per 100,000, with the highest prevalence observed for the cases aged ≥ 65 years (33.2 per 100,000, CI 95% 29.6–37.3). In females, SSc was predominant (86.7% on the total) with an overall sex ratio F/M of 6.5. Nevertheless, males presented a more severe disease, with a lower survival and significant differences in respiratory complications and metabolic comorbidities. Complications and comorbidities such as pulmonary involvement (HR = 1.66, CI 95% 1.17–2.35), congestive heart failure (HR = 2.76, CI 95% 1.80–4.25), subarachnoid and intracerebral haemorrhage (HR = 2.33, CI 95% 1.21–4.48) and malignant neoplasms (HR = 1.63, CI 95% 1.06–2.52), were significantly associated to a lower survival, also after adjustment for age, sex and other SSc-related complications. Disease-modifying antirheumatic drugs, endothelin receptor antagonists, and phosphodiesterase-5 inhibitors were the drugs with the more increasing prevalence of use in the 2008–2017 period. Conclusions The multi-database approach is important in the investigation of rare diseases where it is often difficult to provide accurate epidemiological indicators. A population-based registry can be exploited in synergy with health databases, to provide evidence related to disease outcomes and therapies and to assess the burden of disease, relying on a large cohort of cases. Building an integrated archive of data from multiple databases linking a cohort of patients to their comorbidities, clinical outcomes and survival, is important both in terms of treatment and prevention.

Objective to describe the disease path and the very long-term outcome in a monocentric cohort of patients with Systemic Lupus Erythematosus (SLE). Methods SLE patients with a disease duration of at least 15 years from diagnosis were enrolled. The number of hospitalizations, the disease flares occurred over the disease course and the organ damage accumulation were evaluated at 1, 2, 3, 4, 5, 10 years from diagnosis and at last observation in 2019 as well. Disease state, ongoing therapies and quality of life measures were also assessed at last visit. Results 126 Caucasian SLE patients were included in the analysis (95% female, median age 47.5 IQR 41–53, median disease duration 21 IQR19-26). At last visit, the majority of the patients (78.6%) was on LLDAS (remission included), 53.4% were on GC treatment and 35.7% on immunosuppressant. Furthermore, 53.2% had at least one organ damage. The majority of patients (66.7%) presented a relapsing-remitting course, for a total of 158 flares during the disease course (incidence rate: 0.79/patient-year); moreover, 84.9% of the cohort experienced at least one hospital admission, amounting to a total of 328 hospitalizations (incidence rate: 0.85/patient-year). The main reason for admission was disease activity, while the percentage of hospitalizations due to other causes has been growing over the 10 years of follow-up. Conclusion after a very long period of disease, most of the patients with SLE are in remission and are not taking GC therapy; however, the risk of incurring in disease flare remains a real problem.

To perform a semiquantitative and quantitative analysis of interstitial lung disease (ILD), through computed tomography (CT), in different serological subgroups of idiopathic inflammatory myopathies (IIM) patients, to find radiologic and clinical differences of disease related to serology.This was a prospective study, which included 98 IIM patients, divided into serological subgroups: anti-aminoacyl-transfer-RNA-synthetases (anti-ARS) positive and myositis-specific autoantibodies (MSA) negative.For each baseline CT the total semiquantitative score of Warrick (WS) and the automated software (Computer-Aided Lung Informatics for Pathology Evaluation and Rating) quantitative scores interstitial lung disease % (ILD%) and vascular-related structure % (VRS%) were calculated. Pulmonary function tests included total lung capacity % (TLC%), forced vital capacity % (FVC%), and diffusing capacity of the lung for carbon monoxide % (DLCO%).Inverse correlations ( P0.001) between the radiologic scores and the functional scores DLCO% and TLC% were found, the most relevant being between ILD% and DLCO% (ρ=-0.590), VRS% and DLCO% (ρ=-0.549), and WS and DLCO% (ρ=-0.471).Positive correlations between ILD% and VRS% (ρ=0.916; P0.001), WS and ILD% (ρ=0.663; ρ0.001), and WS and VRS% (ρ=0.637; P0.001) were obtained.Statistically significant higher values of WS, ILD%, and VRS% were found in the anti-ARS group (WS=15; ILD%=11; VRS%=3.5) compared with the MSA negative one (WS=2.5; ILD%=0.84; VRS%=2.2).The nonspecific interstitial pneumonia pattern was dominant. No statistically significant differences emerged at pulmonary function tests.In this study, ILD in anti-ARS-positive and MSA-negative groups was defined through semiquantitative and quantitative analysis of lung CT. The inverse correlations between the radiologic scores and TLC% and DLCO% ( P0.001) confirm the role of lung CT in the evaluation of ILD in IIM.

Background/Aims People with inflammatory/autoimmune rheumatic and musculoskeletal diseases (I-RMDs) were excluded from Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) vaccine clinical development programmes; therefore, concerns regarding the safety and effectiveness of SARS-CoV-2 vaccines in this population still exist. Previous studies in people with I-RMDs were small albeit reassuring in terms of the incidence of I-RMD flares and adverse events. Our aim was to describe the safety of vaccines against SARS-CoV-2 in people with I-RMD. Methods Physician-reported registry of I-RMD and non-inflammatory RMD (NI-RMDs) patients vaccinated against SARS-CoV-2. From 5/Feb/2021 to 27/Jul/2021, we collected data on demographics, vaccination, RMD diagnosis, disease activity, immunomodulatory/immunosuppressive treatments, flares, adverse events (AEs) and SARS-CoV-2 breakthrough infections. Data were analysed descriptively. Results The study included 5121 participants from 30 countries, 90% with I-RMDs (n = 4604, 68% female, mean age 60.5 years) and 10% with NI-RMDs (n = 517, 77% female, mean age 71.4). Inflammatory joint diseases (58%), connective tissue diseases (18%) and vasculitis (12%) were the most frequent diagnostic groups; 54% received conventional synthetic disease-modifying anti-rheumatic drugs (DMARDs), 42% biologic DMARDs and 35% immunosuppressants. Most patients received the Pfizer/BioNTech vaccine (70%), 17% AstraZeneca/Oxford and 8% Moderna. In fully vaccinated cases, breakthrough infections were reported in 0.7% of I-RMD patients and 1.1% of NI-RMD patients. I-RMD flares were reported in 4.4% of cases (0.6% severe), 1.5% resulting in medication changes. AEs were reported in 37% of cases (37% I-RMD, 40% NI-RMD), serious AEs in 0.5% (0.4% I-RMD, 1.9% NI-RMD). Conclusion The safety profiles of SARS-CoV-2 vaccines in patients with I-RMD were reassuring, and comparable to patients with NI-RMDs. The majority of patients tolerated their vaccination well with rare reports of I-RMD flare and very rare reports of serious AEs. These findings should provide reassurance to rheumatologists and vaccine recipients, and promote confidence in SARS-CoV-2 vaccine safety in I-RMD patients. Disclosure P.M. Machado: None. S.

Aims of the studyTo analyze the prevalence of self-reported anxiety and depression in a monocentric cohort of patients with Systemic Lupus Erythematosus (SLE); to study the main determinants and the impact on quality of life (QoL).MethodsA cross-sectional observational study including adult outpatients with SLE. Demographic and clinical data were analyzed: indices of disease activity (SELENA-SLEDAI); damage (SLICC-DI); comorbidities and concomitant therapies. The definitions for remission (DORIS) and “Lupus Low Disease Activity State” (LLDAS) were applied. At enrollment, each patient completed the following questionnaires: SF-36, FACIT-Fatigue, Lupus Impact Tracker (LIT), Systemic Lupus Activity Questionnaire (SLAQ), and the Hospital Anxiety and Depression Scale (HADS) in order to self-assess anxiety and depression symptoms. The Student t-test and Chi2 tests were conducted for univariate analysis. The Spearman test was used for linear correlation between continuous data. Multivariate analysis was performed by multiple linear and logistic regression.ResultsOne hundred fifty-four consecutive patients with SLE were enrolled, the majority female and Caucasian with a mean age = 43.3 ± 13.7 years. 79.9% were in LLDAS or remission. 36.4% had a SDI > 1. 13.7% of patients had concomitant fibromyalgia. 37.4% had symptoms indicating anxiety and 25% of depression according to the HADS questionnaire. In the multivariate analysis, patients with active disease were significantly more anxious and depressed (p < 0.01) compared to patients in LLDAS or remission. Fibromyalgia and older age were independently associated with anxiety and depression, respectively (p < 0.05). Active skin involvement was significantly linked to depression (p < 0.05). Higher scores on the HADS questionnaire (higher levels of anxiety and depression) were found to be significantly linked to patients’ perception of higher disease activity and worse quality of life, irrespective of disease activity, age and fibromyalgia.ConclusionSymptoms of anxiety and depression are frequent in SLE patients, including outpatients with mild/moderate disease. Such symptoms have a significant negative impact on QoL and perception of disease activity, regardless of other factors. Moreover, disease activity, advanced age and fibromyalgia appear to be significantly linked to mood disorders. Assessing symptoms of the anxious-depressive spectrum in patients with SLE could lead to improvement in patients’ perception of health status and quality of life.

ObjectiveTo use bioelectrical impedance vector analysis (BIVA) in a cohort of patients with systemic sclerosis (SSc) in order to assess their nutritional status in comparison to other groups of patients and to find any correlation with clinical characteristics and outcome of the disease.MethodsWe retrospectively collected data from 50 SSc patients who underwent BIVA for clinical suspicion of malnutrition and compared them with patients affected by other chronic autoimmune rheumatic diseases (OCAD, n = 27) and those who were only symptomatic of malnutrition but without autoimmune features (n = 15), and with 50 healthy controls (HC).ResultsPatients with SSc presented significantly lower values of phase angle (PhA), basal metabolic rate (BMR), and body cellular mass (BCM), and an increase in extracellular water (ECW; P < 0.01 for all) than HC; instead, there were no significant differences for BMI. No significant differences were found between SSc and OCAD. Among patients with SSc, age directly correlated with ECW (ρ = 0.342, P = 0.015) and inversely with PhA (ρ = –0.366, P = 0.009). Female sex, anemia, hypoalbuminemia, reflux, and early satiety/abdominal distension associated with relevant alterations in BIVA results. BIVA variables were significantly different when cardiopulmonary and microvascular involvement was present. Four patients died during the study: they had significantly (P ≤ 0.01) lower PhA, BMR, and BCM, with an increased ECW.ConclusionBIVA, unlike BMI, allowed an accurate characterization of SSc patients at risk of malnutrition, correlating with serological malnutrition markers, with SSc-specific organ manifestations (cardiopulmonary involvement and microvascular damage), and with mortality. BIVA variables might represent a surrogate marker of damage accrual that leads to malnutrition, thus playing a leading role in the prognostic stratification of SSc patients.

ObjectivePrevious research on coping strategies of patients with SLE showed that there are no absolute adaptive or maladaptive strategies and that the range of potential coping strategies is large and heterogeneous. In this paper, we aimed to identify, in a large sample of patients with SLE (N=3222), the most frequent words used by patients to describe their coping strategies, to group them into significant themes and to test their possible association with specific patient characteristics.MethodsOur analyses were based on the data set of the European survey ‘Living with Lupus in 2020’ (N=3222). Through the T-LAB software, we analysed the answers that adult participants gave to an open-ended question about how they cope with the disease. We identified the most frequent words, and with hierarchical cluster analysis we grouped them into semantic clusters (ie, themes) that were characterised by specific patterns of words. Finally, we tested the possible association between clusters and illustrative variables (sociodemographics, disease characteristics, quality of life).ResultsFive coping strategies were identified, each of them constituting an important percentage of the total word occurrences: positive attitude (22.58%), social support (25.46%), medical treatments (10.77%), healthy habits (20.74%) and avoid stress (20.45%). Each strategy was statistically associated with specific patient characteristics, such as age and organ involvement.ConclusionsLearning to adapt to a lifetime of having SLE may require replacing old coping strategies with more effective ones. Investigating patients’ coping strategies in relation to different patient characteristics represents a useful starting point for developing more targeted and efficacious interventions.

In order to address the main challenges related to the rare diseases (RDs) the European Commission launched the European Reference Networks (ERNs), virtual networks involving healthcare providers (HCPs) across Europe. The mission of the ERNs is to tackle low prevalence and RDs that require highly specialised treatment and a concentration of knowledge and resources. In fact, ERNs offer the potential to give patients and healthcare professionals across the EU access to the best expertise and timely exchange of lifesaving knowledge, trying to make the knowledge travelling more than patients. For this reason, ERNs were established as concrete European infrastructures, and this is particularly crucial in the framework of rare and complex diseases in which no country alone has the whole knowledge and capacity to treat all types of patients. It has been five years since their kick-off launch in Vilnius in 2017. The 24 ERNs have been intensively working on different transversal areas, including patient management, education, clinical practice guidelines, patients' care pathways and many other fundamental topics. The present work is therefore aimed not only at reporting a summary of the main activities and milestones reached so far, but also at celebrating the first 5 years of the ERN on Rare and Complex Connective Tissue and Musculo-skeletal Diseases (ReCONNET), in which the members of the network built together one of the 24 infrastructures that are hopefully going to change the scenario of rare diseases across the EU.

ObjectiveIt is still a matter of debate whether low-dose acetylsalicylic acid (LDASA) should be prescribed to all patients with SLE during pregnancy. This study aimed at investigating the impact of LDASA on pregnancy outcomes in patients with SLE without history of renal involvement and without antiphospholipid antibodies (aPL).MethodsThis is a retrospective analysis of prospectively monitored pregnancies at seven rheumatology centres. Previous/current renal involvement and aPL positivity were the exclusion criteria. Adverse pregnancy outcome (APO) is the composite outcome of the study and included proteinuric pre-eclampsia, preterm delivery Results216 pregnancies in 187 patients were included; 82 pregnancies (38.0%) were exposed to LDASA treatment. No differences in terms of age at conception, disease duration, clinical manifestations, comorbidities and disease flare during pregnancy were observed between patients taking LDASA and those who did not take LDASA during pregnancy. APO was observed in 65 cases (30.1%), including 13 cases (6.1%) of pre-eclampsia. The incidence of all complications was similar in the two groups. However, it is interesting to note that pre-eclampsia had lower frequency in patients taking LDASA versus those not taking LDASA (2.4% vs 8.3%, p=0.14).ConclusionsIn pregnant patients with SLE without renal involvement and were aPL-negative, there is a low risk of severe obstetric complications, such as early pre-eclampsia. LDASA treatment does not provide a statistically significant advantage over these complications. However, a careful individual risk–benefit balance is warranted.

Sjögren's syndrome (SS) is a systemic autoimmune disease that frequently occurs concomitantly with other systemic connective tissue disorders, including rare and complex diseases such as systemic lupus erythematosus (SLE) and systemic sclerosis (SSc). The presence of SS influences the clinical expression of the other autoimmune diseases, thus offering the unique opportunity to explore the similarities in genetic signatures, as well as common environmental and biologic factors modulating the expression of disease phenotypes. In this review, we will specifically discuss the possibility of defining "SS/SLE" and "SS/SSc" as distinct subsets within the context of connective tissue diseases with different clinical expression and outcomes, thus deserving an individualised assessment and personalised medical interventions.

Autoimmune rheumatic diseases (ARD) can affect women and men during fertile age, therefore reproductive health is a priority issue in rheumatology. Many topics need to be considered during preconception counselling: fertility, the impact of disease-related factors on pregnancy outcomes, the influence of pregnancy on disease activity, the compatibility of medications with pregnancy and breastfeeding. Risk stratification and individualized treatment approach elaborated by a multidisciplinary team minimize the risk of adverse pregnancy outcomes (APO). Research has been focused on identifying biomarkers that can be predictive of APO. Specifically, preeclampsia and hypertensive disorders of pregnancy tend to develop more frequently in women with ARD. Placental insufficiency can lead to intrauterine growth restriction and small-for-gestational age newborns. Such APO have been shown to be associated with maternal disease activity in different ARD. Therefore, a key message to be addressed to the woman wishing for a pregnancy and to her family is that treatment with compatible drugs is the best way to ensure maternal and fetal wellbeing. An increasing number of medications have entered the management of ARD, but data about their use in pregnancy and lactation are scarce. More information is needed for most biologic drugs and their biosimilars, and for the so-called small molecules, while there is sufficient evidence to recommend the use of TNF inhibitors if needed for keeping maternal disease under control. Other issues related to the reproductive journey have emerged as “unmet needs”, such as sexual dysfunction, contraception, medically assisted reproduction techniques, long-term outcome of children, and they will be addressed in this review paper. Collaborative research has been instrumental to reach current knowledge and the future will bring novel insights thanks to pregnancy registries and prospective studies that have been established in several Countries and to their joint efforts in merging data.

© Copyright Clinical and Experimental Rheumatology 2022., 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.

The concern about the offspring’s health is one of the reasons for a reduced family size of women with rheumatic diseases (RD). Increased risk of autoimmune diseases (AD) and neurodevelopmental disorders (ND) has been reported in children born to patients with RD. Within a nationwide survey about reproductive issues of women with RD, we aimed at exploring the long-term outcome of their children. By surveying 398 patients who received their diagnosis of RD during childbearing age (before the age of 45), information about the offspring were obtained from 230 women who declared to have had children. A total of 148 (64.3%) patients were affected by connective tissue diseases (CTD) and 82 (35.7%) by chronic arthritis. Data on 299 children (156 males, 52.1%; mean age at the time of interview 17.1 ± 9.7 years) were collected. Twelve children (4.0%), who were born to patients with CTD in 75% of the cases, were affected by AD (8 cases of celiac disease). Eleven children had a certified diagnosis of ND (3.6%; 6 cases of learning disabilities); 9 of them were born to mothers with CTD (5 after maternal diagnosis). No association was found between ND and prenatal exposure to either maternal autoantibodies or anti-rheumatic drugs. Absolute numbers of offspring affected by AD and ND were low in a multicentre cohort of Italian women with RD. This information can be helpful for the counselling about reproductive issues, as the health outcomes of the offspring might not be an issue which discourage women with RD from having children.

ObjectiveA subanalysis of the multicentre Early Lupus inception cohort was performed to investigate the real-world Glucocorticoids (GCs) Use in newly diagnosed systemic lupus erythematosus (SLE) Patients (GULP).MethodsPatients starting prednisone (PDN) ≥5 mg/day and concomitant hydroxychloroquine or immunosuppressant within 12 months of SLE classification were enrolled. Core set variables were recorded at baseline and every 6 months, including changes in PDN dose, European Consensus Lupus Activity Measurement (ECLAM) and Systemic Lupus International Collaborating Clinics damage index. Regression models analysed predictors of tapering PDNResultsThe GULP study included 127 patients with SLE; 73 (57.5%) tapered and maintained PDN ConclusionTapering PDN

ObjectivesTo describe the safety of vaccines against SARS-CoV-2 in people with inflammatory/autoimmune rheumatic and musculoskeletal disease (I-RMD).MethodsPhysician-reported registry of I-RMD and non-inflammatory RMD (NI-RMDs) patients vaccinated against SARS-CoV-2. From 5 February 2021 to 27 July 2021, we collected data on demographics, vaccination, RMD diagnosis, disease activity, immunomodulatory/immunosuppressive treatments, flares, adverse events (AEs) and SARS-CoV-2 breakthrough infections. Data were analysed descriptively.ResultsThe study included 5121 participants from 30 countries, 90% with I-RMDs (n=4604, 68% female, mean age 60.5 years) and 10% with NI-RMDs (n=517, 77% female, mean age 71.4). Inflammatory joint diseases (58%), connective tissue diseases (18%) and vasculitis (12%) were the most frequent diagnostic groups; 54% received conventional synthetic disease-modifying antirheumatic drugs (DMARDs), 42% biological DMARDs and 35% immunosuppressants. Most patients received the Pfizer/BioNTech vaccine (70%), 17% AstraZeneca/Oxford and 8% Moderna. In fully vaccinated cases, breakthrough infections were reported in 0.7% of I-RMD patients and 1.1% of NI-RMD patients. I-RMD flares were reported in 4.4% of cases (0.6% severe), 1.5% resulting in medication changes. AEs were reported in 37% of cases (37% I-RMD, 40% NI-RMD), serious AEs in 0.5% (0.4% I-RMD, 1.9% NI-RMD).ConclusionThe safety profiles of SARS-CoV-2 vaccines in patients with I-RMD was reassuring and comparable with patients with NI-RMDs. The majority of patients tolerated their vaccination well with rare reports of I-RMD flare and very rare reports of serious AEs. These findings should provide reassurance to rheumatologists and vaccine recipients and promote confidence in SARS-CoV-2 vaccine safety in I-RMD patients.

ObjectiveTo map existing organizational care pathways in clinical centers of expertise that care for pregnant women affected by rare and complex connective tissue diseases (rcCTDs).MethodsAn international working group composed of experts in the field of pregnancy in rcCTDs co-designed a survey focused on organizational aspects related to the patient's pathway before, during, and after pregnancy. The survey was distributed to subject experts through referral sampling.ResultsAnswers were collected from 69 centers in 21 countries. Patients with systemic lupus erythematosus and/or antiphospholipid syndrome were followed by more than 90% of centers, whereas those with disorders such as IgG4-related diseases were rarely covered. In the majority of centers, a multidisciplinary team was involved, including an obstetrician/gynecologist in 91.3% of cases and other healthcare professionals less frequently. Respondents indicated that 96% of the centers provided routine pre-pregnancy care, whereas the number of patient visits during pregnancy varied across centers. A formalized care pathway was described in 49.2% of centers, and 20.3% of centers had a predefined protocol for the monitoring of pregnant patients. Access to therapies during pregnancy also was heterogeneous among different centers.ConclusionIn international referral centers, a high level of care is provided to patients with rcCTDs before, during, and after pregnancy. No significant discrepancies were found between European and non-European countries. However, this work highlights a potential benefit to streamlining the care approaches across countries to optimize pregnancy and perinatal outcomes among patients with rcCTDs.

© Copyright Clinical and Experimental Rheumatology 2022, Objectives: The purpose of this study was to review the frequency and clinical presentation of the rarest clinical manifestations of systemic lupus erythematosus (SLE). Methods: A list of 6 rare SLE manifestations were defined: gastrointestinal, liver, pulmonary, cardiac, ocular and neurological manifestations. Each topic was assigned to a pair of authors to perform a literature search and article review. Results: In total, 149 articles were included in the literature review: 37 for gastrointestinal manifestations, 6 for liver manifestations, 27 for pulmonary manifestations, 50 for cardiac manifestations, 16 for ocular manifestations, 13 for neurological manifestations. Gastrointestinal disorders included several clinical presentations with variable frequency (from 0.5% to 10.7% of the cases); liver involvement included lupus-related hepatitis (9.3%) and autoimmune hepatitis (2.3%). The rarest pulmonary manifestations identified were shrinking lung syndrome, described in 1.5% of patients, while interstitial lung disease and lupus pneumonia were reported in 4% and 3% of patients respectively. Myocarditis and pulmonary hypertension were also rarely described in SLE patients although ranging from 0.4-16% and 1-14% respectively, depending on the methodology used for its identification. Ocular manifestations in SLE included some rare manifestations (reported in less than 5% of patients) and lupus retinopathy that is described in 1.2-28.8% of patients depending on methods of ascertainment. Aseptic meningitis and chorea were also confirmed as very rare manifestations being reported in less than 1% and in 0.3-2.4% of cases respectively. Conclusions: The results of this literature review provide the basis for a better understanding of some less-known manifestations of SLE and for stressing the need for a higher awareness in diagnostic and therapeutic protocols regarding these rare disease aspects.
