To develop a score for assessment of patients' symptoms in primary Sjögren's syndrome (SS): the EULAR SS Patient Reported Index (ESSPRI).
Dryness, pain, somatic and mental fatigue were identified as ...the main symptoms of patients with primary SS, in studies developing the Profile of Fatigue and Discomfort (PROFAD) and Sicca Symptoms Inventory (SSI). It was suspected that a single 0-10 numerical scale for each domain was sufficient to assess these symptoms. These four scales were gathered to form the ESSPRI. 230 patients, from 12 countries completed the ESSPRI, SSI and PROFAD questionnaires and a 0-10 patient global assessment (PGA). Correlations between each symptom and PGA were obtained. Multiple regression modelling, using PGA as 'gold standard' was used to select domains and estimate their weights.
PGA had good correlation with dryness, limb pain, fatigue and mental fatigue (r=0.49-0.59, all p<0.0001), but correlated less well with individual dryness features. In multivariate analysis, dryness, limb pain and fatigue, but not mental fatigue, were significantly associated with PGA; weights derived from the regression were identical for these three domains. Thus, ESSPRI was redefined as the mean of the three scales: dryness, limb pain and fatigue. Lastly, ESSPRI significantly correlated with PGA (r=0.70), PROFAD (r=0.73) and SSI (r=0.66).
ESSPRI is a very simple index designed to measure patients' symptoms in primary SS. It has good construct validity and is well correlated with SSI and PROFAD. ESSPRI should now be validated for use as an outcome measure in clinical trials.
Anti-synthetase syndrome (anti-SS) is frequently associated with myositis and interstitial lung disease (ILD). We evaluated prospectively, in a multicenter, open-label, phase II study, the efficacy ...of rituximab on muscle and lung outcomes.
Patients were enrolled if they were refractory to conventional treatments (prednisone and at least 2 immunosuppressants). They received 1 g of rituximab at D0, D15, and M6. The primary endpoint was muscular improvement based on manual muscular testing (MMT10, Kendall score in 10 muscles) at M12. Secondary endpoints were normalization of creatine kinase (CK) level, ILD improvement based on forced vital capacity and/or diffuse capacity for carbon monoxide, and number and/or doses of associated immunosuppressants.
Twelve patients were enrolled, and 10 completed the study. Only 2 patients presented an improvement of at least 4 points on at least two muscle groups (primary end-point). Overall, seven patients had an increase of at least 4 points on MMT10. CK level decreased from 399 IU/L (range, 48-11,718) to 74.5 IU/L (range, 40-47,857). Corticosteroid doses decreased from 52.5 mg/d (range, 10-70) to 9 mg/d (range, 7-65) and six patients had a decrease in the burden of their associated immunosuppressants. At baseline, all 10 patients presented with ILD. At M12, improvement of ILD was observed in 5 out of the 10 patients, stabilization in 4, and worsening in 1.
This pilot study of rituximab treatment in patients with refractory anti-SS provided data on evolution of muscular and pulmonary parameters. Rituximab should now be evaluated in a larger, controlled study for this homogenous group of patients.

To assess the survival and prognostic factors in patients with newly diagnosed incident systemic sclerosis (SSc)-associated pulmonary arterial hypertension (PAH) in the modern management era.
...Prospectively enrolled SSc patients in the French PAH Network between January 2006 and November 2009, with newly diagnosed PAH and no interstitial lung disease, were analysed (85 patients, mean age 64.9±12.2 years). Median follow-up after PAH diagnosis was 2.32 years.
A majority of patients were in NYHA functional class III-IV (79%). Overall survival was 90% (95% CI 81% to 95%), 78% (95% CI 67% to 86%) and 56% (95% CI 42% to 68%) at 1, 2 and 3 years from PAH diagnosis, respectively. Age (HR: 1.05, 95% CI 1.01 to 1.09, p=0.012) and cardiac index (HR: 0.49, 95% CI 0.27 to 0.89, p=0.019) were significant predictors in the univariate analysis. We also observed strong trends for gender, SSc subtypes, New York Heart Association functional class, pulmonary vascular resistance and capacitance to be significant predictors in the univariate analysis. Conversely, six-min walk distance, mean pulmonary arterial and right atrial pressures were not significant predictors. In the multivariate model, gender was the only independent factor associated with survival (HR: 4.76, 95% CI 1.35 to 16.66, p=0.015 for male gender).
Incident SSc-associated PAH remains a devastating disease even in the modern management era. Age, male gender and cardiac index were the main prognosis factors in this cohort of patients. Early detection of less severe patients should be a priority.
Objective
To analyze the factors associated with response to anti–tumor necrosis factor (anti‐TNF) treatment and compare the efficacy and safety of infliximab (IFX) and adalimumab (ADA) in patients ...with refractory noninfectious uveitis.
Methods
This was a multicenter observational study of 160 patients (39% men and 61% women; median age 31 years interquartile range 21–42) with uveitis that had been refractory to other therapies, who were treated with anti‐TNF (IFX 5 mg/kg at weeks 0, 2, 6, and then every 5–6 weeks n = 98 or ADA 40 mg every 2 weeks n = 62). Factors associated with complete response were assessed by multivariate analysis. Efficacy and safety of IFX versus ADA were compared using a propensity score approach with baseline characteristics taken into account. Subdistribution hazard ratios (SHRs) and 95% confidence intervals (95% CIs) were calculated.
Results
The main etiologies of uveitis included Behçet's disease (BD) (36%), juvenile idiopathic arthritis (22%), spondyloarthropathy (10%), and sarcoidosis (6%). The overall response rate at 6 and 12 months was 87% (26% with complete response) and 93% (28% with complete response), respectively. The median time to complete response was 2 months. In multivariate analysis, BD and occurrence of >5 uveitis flares before anti‐TNF initiation were associated with complete response to anti‐TNF (SHR 2.52 95% CI 1.35–4.71, P = 0.004 and SHR 1.97 95% CI 1.02–3.84, P = 0.045, respectively). Side effects were reported in 28% of patients, including serious adverse events in 13%. IFX and ADA did not differ significantly in terms of occurrence of complete response (SHR 0.65 95% CI 0.25–1.71, P = 0.39), serious side effects (SHR 0.22 95% CI 0.04–1.25, P = 0.089), or event‐free survival (SHR 0.55 95% CI 0.28–1.08, P = 0.083).
Conclusion
Anti‐TNF treatment is highly effective in refractory inflammatory uveitis. BD is associated with increased odds of response. IFX and ADA appear to be equivalent in terms of efficacy.
To evaluate the efficacy and safety of rituximab in patients with primary Sjögren's syndrome (pSS).
The AutoImmune and Rituximab registry has included 86 patients with pSS treated with rituximab, ...prospectivey followed up every 6 months for 5 years.
Seventy-eight patients with pSS (11 men, 67 women), who already had at least one follow-up visit, were analysed. Median age was 59.8 years (29-83), median duration of disease was 11.9 years (3-32). Indications for treatment were systemic involvement for 74 patients and only severe glandular involvement in four patients. The median European Sjögren's Syndrome disease activity index (ESSDAI) was 11 (2-31). 17 patients were concomitantly treated with another immunosuppressant agent. Median follow-up was 34.9 months (6-81.4) (226 patient-years). Overall efficacy according to the treating physician was observed in 47 patients (60%) after the first cycle of rituximab. Median ESSDAI decreased from 11 (2-31) to 7.5 (0-26) (p<0.0001). Median dosage of corticosteroid decreased from 17.6 mg/day (3-60) to 10.8 mg/day (p=0.1). Forty-one patients were retreated with rituximab. Four infusion reactions and one delayed serum sickness-like disease resulted in rituximab discontinuation. Three serious infections (1.3/100 patient-years) and two cancer-related deaths occurred.
In common practice, the use of rituximab in pSS is mostly restricted to patients with systemic involvement. This prospective study shows good efficacy and tolerance of rituximab in patients with pSS and systemic involvement.
Abstract
Background
There is a paucity of data on the epidemiology, survival estimates and healthcare resource utilisation and associated costs of patients with progressive fibrosing interstitial ...lung disease (PF-ILD) in France. An algorithm for extracting claims data was developed to indirectly identify and describe patients with PF-ILD in the French national administrative healthcare database.
Methods
The French healthcare database, the Système National des Données de Santé (SNDS), includes data related to ambulatory care, hospitalisations and death for 98.8% of the population. In this study, algorithms based on age, diagnosis and healthcare consumption were created to identify adult patients with PF-ILD other than idiopathic pulmonary fibrosis between 2010 and 2017. Incidence, prevalence, survival estimates, clinical features and healthcare resource usage and costs were described among patients with PF-ILD.
Results
We identified a total of 14,413 patients with PF-ILD. Almost half of them (48.1%) were female and the mean (± standard deviation) age was 68.4 (± 15.0) years. Between 2010 and 2017, the estimated incidence of PF-ILD ranged from 4.0 to 4.7/100,000 person-years and the estimated prevalence from 6.6 to 19.4/100,000 persons. The main diagnostic categories represented were exposure-related ILD other than hypersensitivity pneumonitis (n = 3486; 24.2%), idiopathic interstitial pneumonia (n = 3113; 21.6%) and rheumatoid arthritis-associated ILD (n = 2521; 17.5%). Median overall survival using Kaplan–Meier estimation was 3.7 years from the start of progression. During the study, 95.2% of patients had ≥ 1 hospitalisation for respiratory care and 34.3% were hospitalised in an intensive care unit. The median (interquartile range) total specific cost per patient during the follow-up period was €25,613 (10,622–54,287) and the median annual cost per patient was €18,362 (6856–52,026), of which €11,784 (3003–42,097) was related to hospitalisations. Limitations included the retrospective design and identification of cases through an algorithm in the absence of chest high-resolution computed tomography scans and pulmonary function tests.
Conclusions
This large, real-world, longitudinal study provides important insights into the characteristics, epidemiology and healthcare resource utilisation and costs associated with PF-ILD in France using a comprehensive and exhaustive database, and provides vital evidence that PF-ILD represents a high burden on both patients and healthcare services.

Cerebrovascular ischemic events (CIE) are among the most severe complications of giant cell arteritis (GCA). Heterogeneity between different studies in the definition of GCA-related CIE leads to ...uncertainty regarding their real prevalence. The aim of our study was to evaluate the prevalence and describe the characteristics of GCA-related CIE in a well-phenotyped cohort completed by a meta-analysis of the existing literature.
In this retrospective study performed in the Lille University Hospital, all consecutive patients with GCA according to American College of Rheumatology (ACR) diagnostic criteria were included from January 1, 2010, to December 31, 2020. A systematic review of the literature using MEDLINE and EMBASE was performed. Cohort studies of unselected GCA patients reporting CIE were included in the meta-analysis. We calculated the pooled summary estimate of GCA-related CIE prevalence.
A total of 271 GCA patients (89 males, mean age 72 ± 9 years) were included in the study. Among them, 14 (5.2%) presented with GCA-related CIE including 8 in the vertebrobasilar territory, 5 in the carotid territory, and 1 patient having multifocal ischemic and hemorrhagic strokes related to intra-cranial vasculitis. Fourteen studies were included in the meta-analysis, representing a total population of 3553 patients. The pooled prevalence of GCA-related CIE was 4% (95% CI 3-6, I
= 68%). Lower body mass index (BMI), vertebral artery thrombosis on Doppler US (17% vs 0.8%, p = 0.012), vertebral arteries involvement (50% vs 3.4%, p < 0.001) and intracranial arteries involvement (50% vs 1.8%, p < 0.001) on computed tomography angiography (CTA) and/or magnetic resonance angiography (MRA), and axillary arteries involvement on positron emission computed tomography (PET/CT) (55% vs 20%, p = 0.016) were more frequent in GCA patients with CIE in our population.
The pooled prevalence of GCA-related CIE was 4%. Our cohort identified an association between GCA-related CIE, lower BMI, and vertebral, intracranial, and axillary arteries involvement on various imaging modalities.
To analyze the clinical and immunological characteristics at enrollment in a large prospective cohort of patients with primary Sjögren's syndrome (pSS) and to investigate the association between ...serum BAFF, beta2-microglobulin and free light chains of immunoglobulins and systemic disease activity at enrollment.
Three hundred and ninety five patients with pSS according to American-European Consensus Criteria were included from fifteen centers of Rheumatology and Internal Medicine in the "Assessment of Systemic Signs and Evolution of Sjögren's Syndrome" (ASSESS) 5-year prospective cohort. At enrollment, serum markers were assessed as well as activity of the disease measured with the EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI).
Patient median age was 58 (25(th)-75(th): 51-67) and median disease duration was 5 (2-9) years. Median ESSDAI at enrollment was 2 (0-7) with 30.9% of patients having features of systemic involvement. Patients with elevated BAFF, beta2-microglobulin and kappa, lambda FLCS had higher ESSDAI scores at enrollment (4 2-11 vs 2 0-7, P = 0.03; 4 1-11 vs 2 0-7, P< 0.0001); 4 2-10 vs 2 0-6.6, P< 0.0001 and 4 2-8.2 vs 2 0-7.0, P = 0.02, respectively). In multivariate analysis, increased beta2-microglobulin, kappa and lambda FLCs were associated with a higher ESSDAI score. Median BAFF and beta2-microglobulin were higher in the 16 patients with history of lymphoma (1173.3(873.1-3665.5) vs 898.9 (715.9-1187.2) pg/ml, P = 0.01 and 2.6 (2.2-2.9) vs 2.1 (1.8-2.6) mg/l, P = 0.04, respectively).
In pSS, higher levels of beta2-microglobulin and free light chains of immunoglobulins are associated with increased systemic disease activity.
Objective
Connective tissue diseases (CTDs) are associated with several interstitial lung diseases. The aim of this study was to describe the recently individualized syndrome of combined pulmonary ...fibrosis and emphysema (CPFE) in a population of patients with CTD.
Methods
In this multicenter study, we retrospectively investigated data from patients with CTD who also have CPFE. The demographic characteristics of the patients, the results of pulmonary function testing, high‐resolution computed tomography, lung biopsy, and treatment, and the outcomes of the patients were analyzed.
Results
Data from 34 patients with CTD who were followed up for a mean ± SD duration of 8.3 ± 7.0 years were analyzed. Eighteen of the patients had rheumatoid arthritis (RA), 10 had systemic sclerosis (SSc), 4 had mixed or overlap CTD, and 2 had other CTDs. The mean ± SD age of the patients was 57 ± 11 years, 23 were men, and 30 were current or former smokers. High‐resolution computed tomography revealed emphysema of the upper lung zones and pulmonary fibrosis of the lower zones in all patients, and all patients exhibited dyspnea during exercise. Moderately impaired pulmonary function test results and markedly reduced carbon monoxide transfer capacity were observed. Five patients with SSc exhibited pulmonary hypertension. Four patients died during followup. Patients with CTD and CPFE were significantly younger than an historical control group of patients with idiopathic CPFE and more frequently were female. In addition, patients with CTD and CPFE had higher lung volumes, lower diffusion capacity, higher pulmonary pressures, and more frequently were male than those with CTD and lung fibrosis without emphysema.
Conclusion
CPFE warrants inclusion as a novel, distinct pulmonary manifestation within the spectrum of CTD‐associated lung diseases in smokers or former smokers, especially in patients with RA or SSc.
Limited cutaneous systemic sclerosis (LcSSc) is the most common subset of SSc but it has been overlooked in the past years. At a time at which clinical trials focus on diffuse cutaneous SSc (DcSSc) ...we aimed at clarifying the outcomes of LcSSc and at evaluating whether potential drug positioned in DcSSc may also be used in LcSSc.
The EUSTAR database was used to investigate skin, lung and peripheral vasculopathy outcomes in LcSSc. Worsening of skin fibrosis, ILD and peripheral vasculopathy were defined by an increase in modified Rodnan skin score (mRSS) > 3.5 points, a decrease of FVC > 10% in patients with ILD at baseline, and by the development of new digital ulcers (DU) in patients without DU at baseline.
8013 LcSSc and 4786 DcSSc patients were included. In contrast to DcSSc, skin disease was remarkably stable in the majority of LcSSc patients with >80% having a change lower than ±4 units of mRSS at 12, 24 and 36 months follow-up. Conversely, FVC changes over time were very similar between LcSSc and DcSSc. Regarding DU, numbers of patients with new DU over time seemed to be almost similar between the two subsets.
LcSSc patients have a low mRSS at baseline with marginal changes with time. Conversely, SSc-ILD can be as progressive as in DcSSc supporting the inclusion of LcSSc patients in SSc-ILD trials and suggesting potential benefit of any anti-ILD drugs. Similarly, although slightly less common, DU should receive the same attention in the two subsets.
•LcSSc patients have a low mRSS at baseline with marginal changes with time.•Similar rates of ILD progression were observed between LcSSc and DcSSc.•Rates of patients with new DU over time were almost similar between the two subsets.
