Muscle involvement in systemic sclerosis: high mortality not associated with nature of histological lesions.

OBJECTIVES: The aim of this study was to determine the association between different histological patterns and prognosis in patients with SSc and histologically proven muscle involvement. METHODS: A multicentre retrospective study was conducted of a cohort of scleroderma patients who had undergone muscle biopsy. The biopsies were reviewed in a coordinated manner to classify patients based on histological findings. Three different patterns were observed: fibrosing myopathy (FM), inflammatory myopathy (IM) and necrotizing myopathy (NM). Rates of survival, muscle relapse, and cardiac and pulmonary events were compared between these three groups. RESULTS: Among 71 scleroderma patients with muscle biopsy specimens available for review, 33 (46.5%) were classified in the FM group, 18 (25.5%) in the IM group, and 20 (28%) in the NM group. The median follow-up time was 6.4 years (interquartile range, 2.2-10.9 years) and 21 patients died during follow-up, primarily from heart disease and infections. The 10-year survival rate after the first non-Raynaud's disease symptom was 80% and the cumulative incidence of muscle relapse was 25%. Neither factor differed significantly between the three groups. The risk of pulmonary events was lowest in the OM group, significantly lower than in the FM group (hazard ratio, 0.17; 95% CI, 0.04-0.67) and non-significantly lower than in the IMNM group (hazard ratio, 0.28; 95% CI, 0.06-1.24). The risk of cardiac events did not differ significantly between the three groups. CONCLUSION: The mortality rate of scleroderma patients with muscle involvement was not associated with their histological patterns.

[Role of university hospital doctors specialized in internal medicine in health professions training and institutions in France: Survey of the National College of Teachers of Internal Medicine (CEMI)]. / Rôle des médecins hospitalo-universitaires de médecine interne dans la formation aux métiers de la santé et au sein des institutions en France : enquête du Collège National des Enseignants de Médecine Interne (CEMI).

RATIONALE: On the occasion of the General stage meeting of Internal Medicine, the National College of Internal Medicine Teachers (CEMI) conducted a survey on teaching activity among all French university hospital (HU) internal medicine specialists. METHOD: The survey was carried out in September 2023 by sending an email to 101 hospital practitioners university professors (PU-PH) and 18 hospital practitioners assistant professors (MCU-PH) of internal medicine in subsection 53-01 of the National council of universities (CNU), as well as to the 11 HU internists working in immunology (subsection 47-01) or therapeutics (subsection 48-04). RESULTS: Seventy-three HUs (56.1%) responded to the survey, including 65 PU-PH, 7 MCU-PH and 1 university hospital practitioner (PHU). Internal medicine HUs participate in faculty teaching: 80% are responsible for teaching, 30% are responsible for the year or cycle or lead committees and 40% have had or have an elected mandate at the faculty or at university. Internal medicine HU are involved in the teaching of semiology during the first cycle of medical studies, but also in pharmaceutical sciences, dentistry, midwifery and in paramedical training. They are very invested in the implementation of the second cycle reform and 80% are involved in the preparation of Objective Structured Clinical Examinations (ECOS), mainly as examiners (90%). They also participate in teaching using simulation (60%), teaching advanced practice nurses (IPA) (25%), and writing CEMI books (75%). For ECOS, 90% participate as examiners, 60% participate in teaching using simulation, 25% are involved in teaching advanced practice nurses (IPA), 75% participated in the writing of CEMI works. Eight (12%) internal medicine HUs co-facilitate training with patients and 26 (38%) participate in master's courses at the Faculty of Sciences. Finally, 94% are affiliated with a research unit and 48% supervise university theses students. CONCLUSION: Internal medicine universities teachers have a strong educational commitment, particularly in semiology and in the reform of the second cycle of medical studies with ECOS and simulation.

[Trends in the choice of internal medicine (and clinical immunology) at the end of the national ranking examination since 2010]. / Évolution du choix de la médecine interne (et immunologie clinique) à l'issue des épreuves classantes nationales depuis 2010.

INTRODUCTION: The 2017 reform of the third cycle of medical studies (R3C) was accompanied by modifications in the formats and number of specialty diplomas. The aim of this study was to investigate the evolution of the choice of the internal medicine and clinical immunology specialty before and after 2017. METHODS: We used the median ranking and its evolution, as well as incoming and outgoing remorse rights, as markers of attractiveness. Data on the number of position offered, rankings and affectation were collected from decrees published in the French "Journal Officiel" each year. A survey conducted by the "Amicale des Jeunes Internistes" investigated the reasons for the outgoing or incoming rights to remorse. RESULTS: Before 2017, internal medicine was accessible to 52% of students on average, with a median rank of 1118 [339-2640]. From 2017 onwards, the internal medicine specialty was accessible to an average of 76.6% of students, with a median rank of 2772 [1039-5155]. The balance of incoming and outgoing remorse rights was -4.7% before 2017 and varied between -4.1 and -12.4% from 2017. CONCLUSION: Since 2017, the median and cut-off ranks of students choosing internal medicine specialty have increased, and balance of incoming and outgoing remorse rights was increasingly negative. A reflection on the attractiveness of the internal medicine specialty is undertaken by the National College of Internal Medicine Teachers in order to make the richness of the specialty and its different modes of practice known to future residents.

Cluster analysis of clinical manifestations assigns systemic lupus erythematosus-phenotype subgroups: A multicentre study on 440 patients.

OBJECTIVE: Systemic lupus erythematous (SLE) is a heterogenous disease characterised by a large panel of autoantibodies and a wide spectrum of clinical signs and symptoms that engender different outcomes. We aimed to identify distinct, homogeneous SLE patients' phenotypes. METHODS: This retrospective study enrolled SLE patients meeting the Systemic Lupus International Collaborating Clinics (SLICC) classification criteria, enrolled in the French multicentre "APS (antiphospholipid syndrome) and SLE" Registry. Based on 29 variables selected to cover a broad range of clinical and laboratory (excluding autoantibodies) SLE manifestations, unsupervised multiple correspondence analysis followed by hierarchical ascendent-clustering analysis assigned different phenotypes. RESULTS: We included 440 patients, mostly women (94.3%). Median age at SLE diagnosis was 24 (IQR 19-32) years. Cluster analysis yielded three distinct subgroups based on cumulative clinical manifestations, not autoantibody pattern. Cluster 1 (n=91) comprised mostly Caucasian patients, with APS-associated clinical and biological manifestations, e.g., livedo, seizure, thrombocytopaenia and haemolytic anaemia. Cluster 2 (n=221), the largest, included patients with mild clinical manifestations, mainly articular, more frequently associated with Sjögren's syndrome and with less frequent autoantibody-positivity. Cluster 3 (n=128) consisted of patients with the largest panel of SLE-specific clinical manifestations (cutaneous, articular, proliferative nephritis, pleural, cardiac and haematological), the most frequent autoantibody-positivity, low complement levels, and more often of Asian and sub-Saharan African origin. CONCLUSION: This unsupervised clustering method distinguished three distinct SLE patient subgroups, highlighting SLE heterogeneity.

Hydroxychloroquine levels in pregnancy and materno-fetal outcomes in Systemic Lupus Erythematosus patients.

OBJECTIVES: Data about hydroxychloroquine (HCQ) levels during pregnancy are sparse. We assessed HCQ whole blood levels at first trimester of pregnancy as a potential predictor of maternal and obstetric/fetal outcomes in patients with systemic lupus erythematosus (SLE). METHODS: We included pregnant SLE patients enrolled in the prospective GR2 study receiving HCQ, with at least one available first-trimester whole-blood HCQ assay. We evaluated several cut-offs for HCQ whole blood levels, including ≤200 ng/ml for severe non-adherence. Primary outcomes were maternal flares during the second and third trimesters of pregnancy, and adverse pregnancy outcomes (APOs: fetal/neonatal death, placental insufficiency with preterm delivery, and small-for-gestational-age neonates). RESULTS: We included 174 patients (median age: 32.1 years, IQR 28.8-35.2). Thirty (17.2%) patients had flares, 4 (2.3%) being severe. APOs occurred in 28 patients (16.1%). There were no significant differences in APOs by HCQ level for either those with subtherapeutic HCQ levels (≤500 ng/ml vs >500 ng/ml: 23.5% vs 14.3%, p = 0.19) or those with non-adherent HCQ levels (≤200 ng/ml vs >200 ng/ml: 20.0% vs 15.7%, p = 0.71). Similarly, the overall rate of maternal flares did not differ significantly by HCQ level cut-off, but patients with subtherapeutic (HCQ ≤500 ng/ml: 8.8% vs 0.7%, p = 0.02) and non-adherent HCQ levels (≤200 ng/ml: 13.3% vs 1.3%, p = 0.04) had significantly more severe flares. CONCLUSION: In this large prospective study of pregnant SLE patients, first-trimester subtherapeutic (≤500 ng/ml) and severe non-adherent (≤200 ng/ml) HCQ levels were associated with severe maternal flares, but not with APOs. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02450396.

Physical activity during COVID-19 in people with systemic sclerosis: A Scleroderma Patient-centred Intervention Network COVID-19 Cohort longitudinal study.

Introduction/Objective: People with systemic sclerosis (SSc) face barriers to physical activity. Few studies have described physical activity in SSc, and none have explored physical activity longitudinally during COVID-19. We evaluated physical activity from April 2020 to March 2022 among people with SSc. Methods: The Scleroderma Patient-centred Intervention Network (SPIN) COVID-19 Cohort was launched in April 2020 and included participants from the ongoing SPIN Cohort plus external enrolees. Participants completed measures bi-weekly through July 2020, then every 4 weeks afterwards (28 assessments). Physical activity was assessed via the self-reported International Physical Activity Questionnaire-Elderly. Analyses included estimated means with 95% confidence intervals for physical activity across assessments. Missing data were imputed for main analyses. Sensitivity analyses included evaluating only participants who completed >90% of items for >21 of 28 possible assessments ('completers') and stratified analyses by sex, age, country and SSc subtype. Results: A total of 800 people with SSc enrolled. Mean age was 55.6 (standard deviation (SD) = 12.6) years. Physical activity significantly decreased from April 2020 to March 2021 (standardized mean difference (SMD) = -0.17, 95% confidence interval (CI) = -0.26 to -0.07) and was stable from March 2021 to March 2022 (SMD = -0.05, 95% CI = -0.15 to 0.05). Results were similar for completers and subgroups. The proportion of participants who met World Health Organization minimum physical activity recommendations of at least 150 min of moderate-to-vigorous activity per week ranged from 63% to 82% across assessments. Conclusion: Physical activity decreased by a relatively small amount, on average, across the pandemic. Most participants met recommended physical activity levels.

Assessing hand and global disability in a cohort of Algerian patients with systemic sclerosis: Construct validities of the Arab Hand Function Index and the Arabic Health Assessment Questionnaire.

Objective: The study aimed to assess the construct validity of the Arab Hand Function Index and the Arabic Health Assessment Questionnaire in Algerian patients with systemic sclerosis. Methods: Consecutive Algerian patients who fulfilled the American College of Rheumatology/European League Against Rheumatism criteria for systemic sclerosis were included. In addition to disease characteristics, global disability and hand disability were assessed using the Arabic Health Assessment Questionnaire and the Arab Hand Function Index, respectively. Construct validity was assessed by convergent and divergent validity (Spearman's rank correlation coefficient) and factor analysis. The scale reliability was assessed using the Cronbach's alpha. Results: We evaluated 100 systemic sclerosis patients (83 females) of mean ± standard deviation age 46.7 ± 12.3 years, including 59 limited cutaneous systemic sclerosis and 41 diffuse cutaneous systemic sclerosis. Raynaud's phenomenon was detected in 99 patients and digital ulcers in 25. Gastrointestinal tract involvement and interstitial lung disease were detected in 86/100 (86%) and 46/72 (63.9%) patients, respectively. Anti-topoisomerase I and anti-centromere antibodies were detected in 33/76 (43.4%) and 23/76 (30.3%) patients, respectively. The Arab Hand Function Index had a good construct validity with a total score explaining 61% of the variance of the Arabic Health Assessment Questionnaire which also had a good construct validity. Factor analysis of the Arab Hand Function Index and the Arabic Health Assessment Questionnaire items extracted two factors explaining 64% of the variance for the Arab Hand Function Index and one factor explaining 55% of the variance for the Arabic Health Assessment Questionnaire. The Arab Hand Function Index and the Arabic Health Assessment Questionnaire were reliable questionnaires with a Cronbach's alpha >0.8. Conclusion: In Algerian patients with systemic sclerosis, Arab Hand Function Index and Arabic Health Assessment Questionnaire have a good construct validity and reliability.

COVID-19 vaccinations and infections among individuals with systemic sclerosis: A Scleroderma Patient-centered Intervention Network (SPIN) Cohort study.

BACKGROUND/PURPOSE: We previously surveyed adults with systemic sclerosis (SSc) regarding COVID-19 vaccination in April-May 2021. The objective of the present study was to update through June-July 2022 and assess self-reported (1) COVID-19 vaccination rates, including boosters; (2) vaccine-related adverse events; (3) peri­vaccination immunosuppressive medication management; (4) vaccine hesitancy; and (5) prevalence and severity of COVID-19 infections. METHODS: In April-May 2021 and June-July 2022, SPIN Cohort participants completed surveys on COVID-19 vaccination and infection. Primary vaccine series was defined according to the standard for each COVID-19 vaccine; additional vaccine administrations were considered booster doses. Fully vaccinated was defined as having completed a primary vaccine series and at least one booster dose. RESULTS: 544 participants completed the 2021 survey only, 101 the 2022 survey only, and 388 both surveys. Among 489 participants with 2022 data, 437 (89 %) had received both primary and booster vaccines. Among all 1,033 participants, 960 (93 %) received at least one dose. At least one adverse reaction was reported by 34 % (330 of 960 participants) following first, 48 % (314 of 657 participants) following second, and 34 % (147 of 437 participants) following booster vaccine doses (primarily sore arm and fatigue); no severe adverse reactions were reported. SSc symptom worsening was reported in 6 % (53 of 960) after the first, 6 % after the second (39 of 657), and 4 % (17 of 437) after the booster dose. Of participants taking methotrexate or mycophenolate (including Cellcept or Myfortic), 34 of 266 (13 %) reported that they temporarily stopped or decreased their medication at the first dose, 32 of 215 (15 %) at the second dose, and 28 of 148 (19 %) for booster vaccination. Of 52 individuals not fully vaccinated with primary and booster doses in 2022, 29 (56 %) reported worry about vaccine related SSc flares. 172 of 489 (35 %) 2022 participants reported a history of at least one COVID-19 infection; 114 (66 %) occurred after receiving at least a primary vaccine series. Among initial COVID-19 infections, 9 (5 %) were asymptomatic, 66 (38 %) involved mild symptoms, 82 (48 %) moderate symptoms, and 15 (9 %) required hospitalization. CONCLUSION: Most people with SSc in the study were fully vaccinated, and most continued their methotrexate or mycophenolate post-primary and booster vaccinations. Over half of vaccine-hesitant participants were concerned regarding risk of SSc flare; however, few vaccinated participants reported this. These data may be useful for counselling people with SSc regarding COVID-19 vaccine safety and outcomes.

Minimal Detectable Changes of the HAQ-DI, PROMIS-29v2.0 Domains, and PHQ-8 in Systemic Sclerosis: A SPIN Cohort Cross-Sectional Study.

OBJECTIVE: Systemic sclerosis (SSc) is a rare, chronic, autoimmune disorder associated with disability, diminished physical function, fatigue, pain, and mental health concerns. We assessed minimal detectable changes (MDCs) of the Health Assessment Questionnaire-Disability Index (HAQ-DI), Patient Reported Outcomes Measurement Information System-29 Profile version 2.0 (PROMIS-29v2.0) domains, and Patient Health Questionnaire-8 (PHQ-8) in SSc. METHODS: Scleroderma Patient-centered Intervention Network Cohort participants completed the HAQ-DI, PROMIS-29v2.0 domains, and PHQ-8 at baseline assessments from April 2014 until August 2023. We estimated MDC95 and MDC90 with 95% confidence intervals (CI) generated via the percentile bootstrapping method resampling 1000 times. We compared MDC estimates by age, sex and SSc subtype. RESULTS: A total of 2,571 participants were included. Most were female (N = 2,241; 87%), and 38% (N = 976) had diffuse SSc. Mean (SD) age was 54.9 (12.7) years and duration since onset of first non-Raynaud phenomenon symptom 10.8 (8.7) years. MDC95 estimate was 0.41 points (95% CI: 0.40 to 0.42) for the HAQ-DI, between 4.88 points (95% CI: 4.72 to 5.05) and 9.02 points (95% CI: 8.80 to 9.23) for the 7 PROMIS-29v2.0 domains, and 5.16 points (95% CI: 5.06 to 5.26) for the PHQ-8. MDC95 estimates were not materially different across subgroups. CONCLUSION: MDC95 and MDC90 estimates were precise and similar across age, sex and SSc subtype groups. HAQ-DI MDC95 and MDC90 were substantially larger than previous estimates of HAQ-DI minimal important difference from several small studies. Minimally important differences of all measures should be evaluated in large studies using anchor-based methods.

Association of COVID-19 vaccination and anxiety symptoms: A Scleroderma Patient-centered Intervention Network (SPIN) Cohort longitudinal study.

OBJECTIVE: Symptoms of anxiety increased early in the COVID-19 pandemic among people with systemic sclerosis (SSc) then returned to pre-pandemic levels, but this was an aggregate finding and did not evaluate whether vaccination may have contributed to reduced anxiety symptom levels. We investigated whether being vaccinated for COVID-19 was associated with reduced anxiety symptoms among people with SSc. METHODS: The longitudinal Scleroderma Patient-centered Intervention Network (SPIN) COVID-19 Cohort was launched in April 2020 and included participants from the ongoing SPIN Cohort and external enrollees. Participants completed measures bi-weekly through July 2020, then every 4 weeks afterwards through August 2022 (32 assessments). We used linear mixed models to evaluate longitudinal trends of PROMIS Anxiety 4a v1.0 anxiety domain scores and their association with vaccination. RESULTS: Among 517 participants included in analyses, 489 (95%) were vaccinated by September 2021, and no participants were vaccinated subsequently. Except for briefly at the beginning, when few had received a vaccine, and end, when only 28 participants remained unvaccinated, anxiety symptom trajectories were largely overlapping. Participants who were never vaccinated had higher anxiety symptoms by August 2022, but there were no other differences, and receiving a vaccination did not appear to change anxiety symptom trajectories meaningfully. CONCLUSION: Vaccination did not appear to influence changes in anxiety symptoms among vulnerable people with SSc during the COVID-19 pandemic. This may be due to people restricting their behavior when they were unvaccinated and returning to more normal social engagement once vaccinated to maintain a steady level of anxiety symptoms.

Risk loci involved in giant cell arteritis susceptibility: a genome-wide association study.

BACKGROUND: Giant cell arteritis is an age-related vasculitis that mainly affects the aorta and its branches in individuals aged 50 years and older. Current options for diagnosis and treatment are scarce, highlighting the need to better understand its underlying pathogenesis. Genome-wide association studies (GWAS) have emerged as a powerful tool for unravelling the pathogenic mechanisms involved in complex diseases. We aimed to characterise the genetic basis of giant cell arteritis by performing the largest GWAS of this vasculitis to date and to assess the functional consequences and clinical implications of identified risk loci. METHODS: We collected and meta-analysed genomic data from patients with giant cell arteritis and healthy controls of European ancestry from ten cohorts across Europe and North America. Eligible patients required confirmation of giant cell arteritis diagnosis by positive temporal artery biopsy, positive temporal artery doppler ultrasonography, or imaging techniques confirming large-vessel vasculitis. We assessed the functional consequences of loci associated with giant cell arteritis using cell enrichment analysis, fine-mapping, and causal gene prioritisation. We also performed a drug repurposing analysis and developed a polygenic risk score to explore the clinical implications of our findings. FINDINGS: We included a total of 3498 patients with giant cell arteritis and 15 550 controls. We identified three novel loci associated with risk of giant cell arteritis. Two loci, MFGE8 (rs8029053; p=4·96 × 10-8; OR 1·19 [95% CI 1·12-1·26]) and VTN (rs704; p=2·75 × 10-9; OR 0·84 [0·79-0·89]), were related to angiogenesis pathways and the third locus, CCDC25 (rs11782624; p=1·28 × 10-8; OR 1·18 [1·12-1·25]), was related to neutrophil extracellular traps (NETs). We also found an association between this vasculitis and HLA region and PLG. Variants associated with giant cell arteritis seemed to fulfil a specific regulatory role in crucial immune cell types. Furthermore, we identified several drugs that could represent promising candidates for treatment of this disease. The polygenic risk score model was able to identify individuals at increased risk of developing giant cell arteritis (90th percentile OR 2·87 [95% CI 2·15-3·82]; p=1·73 × 10-13). INTERPRETATION: We have found several additional loci associated with giant cell arteritis, highlighting the crucial role of angiogenesis in disease susceptibility. Our study represents a step forward in the translation of genomic findings to clinical practice in giant cell arteritis, proposing new treatments and a method to measure genetic predisposition to this vasculitis.

Polypharmacy, drug-drug interactions, and adverse drug reactions among systemic sclerosis patients: A cross-sectional risk factor study.

OBJECTIVES: Polypharmacy, drug-drug interactions (DDI) and related adverse drug reaction (ADR) are understudied in SSc. The aim of this work was to determine the prevalence and determinants of DDI and ADR in a real-life prospective cohort of SSc patients. METHODS: We performed a retrospective analysis of the drug prescriptions of SSc patients admitted to the daily scleroderma clinic between January 2020 and April 2022. DDI were identified using 2 prescription analysis applications, and adjudicated related ADRs occurring during a one-year follow-up were reported. Risk factors for DDI and ADR were identified using multivariate analysis. RESULTS: One hundred and eight SSc patients were included. The median number of medications per patient was 6 [4-9]. Seventy-one (65.7 %) patients had 5 or more medications, and 23 (21.3 %) had 10 or more. Seventy-two (66.7 %) patients had DDIs on their prescriptions at inclusion. Patients with DDIs had more medications than patients without DDIs (7 [5-10] versus 3 [2-5], p < 0.0001). Six (8.3) patients experienced ADRs during the one-year follow-up. Patients with ADRs had more medications (14 [10-18] versus 7 [5-10] p < 0.001) and more DDIs (12 [7-32] versus 3 [1-6]; p < 0.001) than patients without ADRs. Multivariate analysis confirmed that the number of prescribed medications was independently positively associated with DDIs (OR: 2.25 [1.52-3.32], p < 0.0001) as well as with ADRs (OR: 1.68 [1.17-2.40], p < 0.01). CONCLUSIONS: SSc patients are significantly exposed to polypharmacy, DDIs and related ADRs, particularly in cases of severe illness, and especially if 5 or more medications are prescribed.

Severe enterovirus infections in patients with immune-mediated inflammatory diseases receiving anti-CD20 monoclonal antibodies.

OBJECTIVE: Patients with X linked agammaglobulinemia are susceptible to enterovirus (EV) infections. Similarly, severe EV infections have been described in patients with impaired B-cell response following treatment with anti-CD20 monoclonal antibodies (mAbs), mostly in those treated for haematological malignancies. We aimed to describe severe EV infections in patients receiving anti-CD20 mAbs for immune-mediated inflammatory diseases (IMIDs). METHODS: Patients were included following a screening of data collected through the routine surveillance of EV infections coordinated by the National Reference Center and a review of the literature. Additionally, neutralising antibodies were assessed in a patient with chronic EV-A71 meningoencephalitis. RESULTS: Nine original and 17 previously published cases were retrieved. Meningoencephalitis (n=21/26, 81%) associated with EV-positive cerebrospinal fluid (n=20/22, 91%) was the most common manifestation. The mortality rate was high (27%). EV was the only causal agents in all reported cases. Patients received multiple anti-CD20 mAbs infusions (median 8 (5-10)), resulting in complete B-cell depletion and moderate hypogammaglobulinemia (median 4.9 g/L (4.3-6.7)), and had limited concomitant immunosuppressive treatments. Finally, in a patient with EV-A71 meningoencephalitis, a lack of B-cell response to EV was shown. CONCLUSION: EV infection should be evoked in patients with IMIDs presenting with atypical organ involvement, especially meningoencephalitis. Anti-CD20 mAbs may lead to impaired B-cell response against EV, although an underlying primary immunodeficiency should systematically be discussed.

Anti-U1RNP antibodies are associated with a distinct clinical phenotype and a worse survival in patients with systemic sclerosis.

OBJECTIVES: To clarify the impact of anti-U1RNP antibodies on the clinical features and prognosis of patients with SSc. METHODS: We conducted a monocentric case-control, retrospective, longitudinal study. For each patient with SSc and anti-U1RNP antibodies (SSc-RNP+), one patient with mixed connective tissue disease (MCTD) and 2 SSc patients without anti-U1RNP antibodies (SSc-RNP-) were matched for age, sex, and date of inclusion. RESULTS: Sixty-four SSc-RNP+ patients were compared to 128 SSc-RNP- and 64 MCTD patients. Compared to SSc-RNP-, SSc-RNP+ patients were more often of Afro-Caribbean origin (31.3% vs. 11%, p < 0.01), and more often had an overlap syndrome than SSc-RNP- patients (53.1 % vs. 22.7%, p < 0.0001), overlapping with Sjögren's syndrome (n = 23, 35.9%) and/or systemic lupus erythematosus (n = 19, 29.7%). SSc-RNP+ patients were distinctly different from MCTD patients but less often had joint involvement (p < 0.01). SSc-RNP+ patients more frequently developed interstitial lung disease (ILD) (73.4% vs. 55.5% vs. 31.3%, p < 0.05), pulmonary fibrosis (PF) (60.9% vs. 37.5% vs. 10.9%, p < 0.0001), SSc associated myopathy (29.7% vs. 6.3% vs. 7.8%, p < 0.0001), and kidney involvement (10.9% vs. 2.3% vs. 1.6%, p < 0.05). Over a 200-month follow-up period, SSc-RNP+ patients had worse overall survival (p < 0.05), worse survival without PF occurrence (p < 0.01), ILD or PF progression (p < 0.01 and p < 0.0001). CONCLUSIONS: In SSc patients, anti-U1RNP antibodies are associated with a higher incidence of overlap syndrome, a distinct clinical phenotype, and poorer survival compared to SSc-RNP- and MCTD patients. Our study suggests that SSc-RNP+ patients should be separated from MCTD patients and may constitute an enriched population for progressive lung disease.

The association of resilience and positive mental health in systemic sclerosis: A Scleroderma Patient-centered Intervention Network (SPIN) cohort cross-sectional study.

OBJECTIVE: A previous study using Scleroderma Patient-centered Intervention Network (SPIN) Cohort data identified five classes of people with systemic sclerosis (also known as scleroderma) based on patient-reported somatic (fatigue, pain, sleep) and mental health (anxiety, depression) symptoms and compared indicators of disease severity between classes. Across four classes ("low", "normal", "high", "very high"), there were progressively worse somatic and mental health outcomes and greater disease severity. The fifth ("high/low") class, however, was characterized by high disease severity, fatigue, pain, and sleep but low mental health symptoms. We evaluated resilience across classes and compared resilience between classes. METHODS: Cross-sectional study. SPIN Cohort participants completed the 10-item Connor-Davidson-Resilience Scale (CD-RISC) and PROMIS v2.0 domains between August 2022 and January 2023. We used latent profile modeling to identify five classes as in the previous study and multiple linear regression to compare resilience levels across classes, controlling for sociodemographic and disease variables. RESULTS: Mean CD-RISC score (N = 1054 participants) was 27.7 (standard deviation = 7.3). Resilience decreased progressively across "low" to "normal" to "high" to "very high" classes (mean 4.7 points per step). Based on multiple regression, the "high/low" class exhibited higher resilience scores than the "high" class (6.0 points, 95% confidence interval [CI] 4.9 to 7.1 points; standardized mean difference = 0.83, 95% CI 0.67 to 0.98). CONCLUSIONS: People with worse disease severity and patient-reported outcomes reported substantially lower resilience, except a class of people with high disease severity, fatigue, pain, and sleep disturbance but positive mental health and high resilience.

Factors associated with physical function among people with systemic sclerosis: a SPIN cohort cross-sectional study.

OBJECTIVES: To compare physical function in systemic sclerosis (SSc, scleroderma) to general population normative data and identify associated factors. METHODS: Scleroderma Patient-centered Intervention Network Cohort participants completed the Physical Function domain of the Patient-Reported Outcomes Measurement Information System Version 2 upon enrolment. Multivariable linear regression was used to assess associations of sociodemographic, lifestyle, and disease-related variables. RESULTS: Among 2,385 participants, mean physical function T-score (43.7, SD = 8.9) was ∼2/3 of a standard deviation (SD) below the US general population (mean = 50, SD = 10). Factors associated in multivariable analysis included older age (-0.74 points per SD years, 95% CI -0.78 to -1.08), female sex (-1.35, -2.37 to -0.34), fewer years of education (-0.41 points per SD in years, -0.75 to -0.07), being single, divorced, or widowed (-0.76, -1.48 to -0.03), smoking (-3.14, -4.42 to -1.85), alcohol consumption (0.79 points per SD drinks per week, 0.45-1.14), BMI (-1.41 points per SD, -1.75 to -1.07), diffuse subtype (-1.43, -2.23 to -0.62), gastrointestinal involvement (-2.58, -3.53 to -1.62), digital ulcers (-1.96, -2.94 to -0.98), moderate (-1.94, -2.94 to -0.93) and severe (-1.76, -3.24 to -0.28) small joint contractures, moderate (-2.10, -3.44 to -0.76) and severe (-2.54, -4.64 to -0.44) large joint contractures, interstitial lung disease (-1.52, -2.27 to -0.77), pulmonary arterial hypertension (-3.72, -4.91 to -2.52), rheumatoid arthritis (-2.10, -3.64 to -0.56) and idiopathic inflammatory myositis (-2.10, -3.63 to -0.56). CONCLUSION: Physical function is impaired for many individuals with SSc and associated with multiple disease factors.

Factors associated with satisfaction with social roles and activities among people with systemic sclerosis: a Scleroderma Patient-centered Intervention Network (SPIN) cohort cross-sectional study.

OBJECTIVE: The objectives were to (1) compare satisfaction with social roles and activities in a large multinational systemic sclerosis (SSc) cohort to general population normative data and (2) identify sociodemographic, lifestyle and SSc disease factors associated with satisfaction with social roles and activities. METHODS: Participants in the Scleroderma Patient-centered Intervention Network Cohort completed the Patient Reported Outcomes Information System Version 2 satisfaction with social roles and activities domain questionnaire. Multivariable regression was used to assess associations with sociodemographic, lifestyle and disease factors. RESULTS: Among 2385 participants, mean satisfaction with social roles and activities T-score (48.1, SD=9.9) was slightly lower than the US general population (mean=50, SD=10). Factors independently associated with satisfaction were years of education (0.54 per SD, 95% CI 0.14 to 0.93); non-White race or ethnicity (-1.13, 95% CI -2.18 to -0.08); living in Canada (-1.33, 95% CI -2.40 to -0.26 (reference USA)) or the UK (-2.49, 95% CI -3.92 to -1.06); body mass index (-1.08 per SD, 95% CI -1.47 to -0.69); gastrointestinal involvement (-3.16, 95% CI -4.27 to -2.05); digital ulcers (-1.90, 95% CI -3.05 to -0.76); moderate (-1.62, 95% CI -2.78 to -0.45) or severe (-2.26, 95% CI -3.99 to -0.52) small joint contractures; interstitial lung disease (-1.11, 95% CI -1.97 to -0.25); pulmonary arterial hypertension (-2.69, 95% CI -4.08 to -1.30); rheumatoid arthritis (-2.51, 95% CI -4.28 to -0.73); and Sjogren's syndrome (-2.42, 95% CI -3.96 to -0.88). CONCLUSION: Mean satisfaction with social roles and activities is slightly lower in SSc than the general population and associated with multiple sociodemographic and disease factors.

Consensus statement on the diagnosis and treatment of sclerosing diseases of the skin, Part 2: Scleromyxoedema and scleroedema.

The term 'sclerosing diseases of the skin' comprises specific dermatological entities, which have fibrotic changes of the skin in common. These diseases mostly manifest in different clinical subtypes according to cutaneous and extracutaneous involvement and can sometimes be difficult to distinguish from each other. The present consensus provides an update to the 2017 European Dermatology Forum Guidelines, focusing on characteristic clinical and histopathological features, diagnostic scores and the serum autoantibodies most useful for differential diagnosis. In addition, updated strategies for the first- and advanced-line therapy of sclerosing skin diseases are addressed in detail. Part 2 of this consensus provides clinicians with an overview of the diagnosis and treatment of scleromyxoedema and scleroedema (of Buschke).

Increased Risk of Invasive Aspergillosis in Immunocompromised Patients With Persistent SARS-CoV-2 Viral Shedding >8 Weeks, Retrospective Case-control Study.

Background: Immunocompromised patients now represent the population most at risk for severe coronavirus disease 2019. Persistent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral shedding was reported in these patients ranging from several weeks up to 9 months. We conducted a bicentric retrospective case-control study to identify risk and prognostic factors associated with persistent viral shedding in immunocompromised patients. Material and Methods: Symptomatic immunocompromised adults with persistent SARS-CoV-2 viral shedding >8 weeks were retrospectively included between 1 March 2020 and 24 April 2022 at 2 university hospitals in Paris, France, and matched with a control group consisting of symptomatic immunocompromised patients without persistent viral shedding. Results: Twenty-nine immunocompromised patients with persistent viral shedding were compared with 40 controls. In multivariate analysis, fever and lymphocytopenia (<0.5 G/L) were associated with an increased risk of persistent viral shedding (odds ratio [OR]: 3.3; 95% confidence interval [CI], 1.01-11.09) P = .048 and OR: 4.3; 95% CI, 1.2-14.7; P = .019, respectively). Unvaccinated patients had a 6-fold increased risk of persistent viral shedding (OR, 6.6; 95% CI, 1.7-25.1; P = .006). Patients with persistent viral shedding were at risk of hospitalization (OR: 4.8; 95 CI, 1.5-15.6; P = .008), invasive aspergillosis (OR: 10.17; 95 CI, 1.15-89.8; P = .037) and death (log-rank test <0.01). Conclusions: Vaccine coverage was protective against SARS-CoV-2 persistent viral shedding in immunocompromised patients. This new group of immunocompromised patients with SARS-CoV-2 persistent viral shedding is at risk of developing invasive aspergillosis and death and should therefore be systematically screened for this fungal infection for as long as the viral shedding persists.
