Background:Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with a significant genetic predisposition. Recent studies have identified STAT4 (signal transducers and transcription activators 4) as a susceptibility gene for SLE.Objectives:To investigate the hypothesis of the association of STAT4 rs7574865 G/T polymorphism with the predisposition to SLE in children and its relationship with some of SLE manifestations.Methods:The case-control pilot study included 143 children (39 with SLE and 103 healthy unrelated volunteers as a control group). Diagnosis of SLE was based on 2012 SLICC criteria. STAT4 rs7574865 G/T polymorphism was investigated using allele-specific real-time polymerase chain reaction (RT-PCR).Results:The group of pts with SLE consisted of 29 girls and 10 boys, with an average age of 11.8±3.7 years (from 3 to 17 years) and an average disease duration of 4.1±2.4 years. 79.5% pts had acute cutaneous lupus at the onset, 46.1% - nonscarring alopecia, 71.8% - arthritis, 23.1% - oral and nasal ulcers, 23.1% - serositis, 43.6% - renal involvement, 35.9% –neuropsychiatric disorders. Leucopenia/lymphopenia was found in 71.8% of pts, thrombocytopenia – in 23,1%. ANA were detected in 100% pts, anti-dsDNA – in 79.5%, anti-Sm – in 31.6%, antiphospholipid antibodies - in 7,3%, hypocomplementemia – in 61.5%, positive direct Coombs test – in 35.9 %. Macrophage activation syndrome at the onset was documented in 15.4 % of pts. The distribution of rs7574865 genotypes in the control group showed no significant deviations from the Hardy-Weinberg equilibrium. The distribution of genotype frequencies among pts had statistically significant differences compared to the control (χ2=12.95, p=0.0015): GG-30.8% and 63.1% (p=0.001), GT-56.4% and 33.0% (p=0.018), TT-12.8% and 3.9% (p=0.114), GT+TT - 69.2% and 36.9% (p=0.0005). The frequency of the mutant STAT 4 allele T (polymorphism), was significantly higher in the SLE group than in the control group (41% and 20.4%, respectively; p=0.0007). We identified an association of the T allele with some clinical, laboratory, and immunological disorders in SLE: arthritis (OR 3.9, p=0.0002), acute cutaneous lupus (OR 2.47, p=0.003), nonscarring alopecia (OR 3.12, p=0.002), renal involvement (OR 2.42, p=0.022), leucopenia (OR 2.72, p=0.003), thrombocytopenia (OR 4.88, p=0.002), anti-dsDNA (OR 2.82, p=0.0006), hypocomplementemia (OR 2.34, p=0.012), positive direct Coombs test (OR 3.38, p=0.002).Conclusion:Our pilot study confirmed that the STAT4 rs7574865 G/T polymorphism was associated with the risk of SLE in children and some of SLE manifestations.Disclosure of Interests:None declared

Background:The updated EULAR recommendations for the management of systemic lupus erythematosus (SLE) underline the use of Mycophenolate Mofetil (MMF) in the treatment of different disease related manifestations (1). Several randomized controlled trials have demonstrated the efficacy of MMF in lupus nephritis (LN) patients but only case series and open-labelled trials have analyzed the use of this drug in other than LN features. Moreover, no data are available about the MMF retention rate in a real-life setting.Objectives:The present study aims at evaluating the 5-years drug retention rate (DRR) of MMF in a large monocentric SLE cohort. Secondly, we investigated the influence of MMF in disease activity changes and chronic damage progression.Methods:We performed a longitudinal study including all the SLE patients (ACR 1997 criteria) starting MMF treatment in our Lupus Clinic. Data about indications, mean dosage, duration of treatment and reasons for drug withdrawal were registered. The DRR was estimated using the Kaplan–Meier method. Disease activity and chronic damage were assessed by SLE Disease Activity Index 2000 (SLEDAI-2K) and SLICC Damage Index (SDI), respectively.Results:The present analysis included 162 SLE patients (M/F 22/140, median age at the disease diagnosis 25.5 years, IQR 13). At the beginning of MMF treatment, we registered a median age of 34 months (IQR 21) and a median disease duration of 72 months (IQR 123). The most frequent indications for prescribing MMF were LN (101 patients, 62.3%) and musculoskeletal manifestations (39, 24.1%), followed by neuropsychiatric involvement (10, 6.2%), and others disease related manifestations (12, 7.4%; in particular skin involvement, hematological features, myositis, vasculitis). MMF was administered at a mean daily dosage of 2.1±0.6 grams; no differences in dosage were found between the different indications (p=ns).At the longitudinal analysis, we registered a median treatment duration of 30 months (IQR 55). Figure 1 reported data about DRR: in particular, at 60 months follow-up we observed a DRR of 61.1% for LN patients, which was similar to that registered for patients without renal involvement (NLN) (60.5%; p=ns). Interestingly, the DRR at 60 months was higher in the subgroup of patients treated for joint involvement (75.4%), even without reaching a statistically significant difference. During the observation period, 92 patients (59.2%) discontinued MMF (median treatment duration at discontinuation 25 months, IQR 35). Interestingly, the main cause of withdrawal was the achievement of persistent remission, observed in 20 patients (21.7%), followed by loss of efficacy (19 patients, 20.5%), drug intolerance and pregnancy planning (17 patients for both reasons, 18,4%). Furthermore, our analysis confirmed MMF efficacy, as demonstrated by the significant reduction in SLEDAI-2k values after 4, 12 and 24 months of treatment (p< 0.0001 for all the time-points in comparison with baseline). In addition, MMF resulted able to control chronic damage progression, as demonstrated by the lack of significant increase in SDI values (baseline: 0.6, IQR 1; last observation: 0.93, IQR 1; p=ns).Conclusion:The evaluation of a large SLE cohort demonstrated a good retention rate for MMF. In particular, our results demonstrated that MMF is also a safe and effective drug for SLE manifestation other than LN, in particular for joint involvement. Moreover, it is able to control disease activity and to prevent the progression of chronic damage.References:[1]Fanouriakis A et al.

Introduction: After more than 20 years of sustained work, the Latin American Group for the Study of Lupus (GLADEL) has made a significant number of contributions to the field of lupus, not only in the differential role that race/ethnicity plays in its course and outcome but also in several other studies including the beneficial effects of using antimalarials in lupus patients and the development of consensus guidelines for the treatment of lupus in our region. Methods: A new generation of “Lupus Investigators” in more than 40 centers throughout Latin America has been constituted in order to continue the legacy of the investigators of the original cohort and to launch a novel study of serum and urinary biomarkers in patients with systemic lupus erythematosus. Results: So far, we have recruited 807 patients and 631 controls from 42 Latin-American centers including 339 patients with SLE without renal involvement, 202 patients with SLE with prevalent but inactive renal disease, 176 patients with prevalent and active renal disease and 90 patients with incident lupus nephritis. Conclusions: The different methodological aspects of the GLADEL 2.0 cohort are discussed in this manuscript, including the challenges and difficulties of conducting such an ambitious project.

Objectives. The anti-dsDNA antibodies are a marker for Systemic Lupus Erythematosus (SLE) and 70–98% of patients test positive. We evaluated the demographic, clinical, laboratory, and therapeutical features of a monocentric SLE cohort according to the anti-dsDNA status.Methods. We identified three groups: anti-dsDNA + (persistent positivity); anti-dsDNA ± (initial positivity and subsequent negativity during disease course); anti-dsDNA − (persistent negativity). Disease activity was assessed by the European Consensus Lupus Activity Measurement (ECLAM).Results. We evaluated 393 patients (anti-dsDNA +: 62.3%; anti-dsDNA ±: 13.3%; anti-dsDNA −: 24.4%). The renal involvement was significantly more frequent in anti-dsDNA + (30.2%), compared with anti-dsDNA ± and anti-dsDNA − (21.1% and 18.7%, resp.;P=0.001). Serositis resulted significantly more frequent in anti-dsDNA − (82.3%) compared to anti-dsDNA + and anti-dsDNA ± (20.8% and 13.4%, resp.;P<0.0001). The reduction of C4 serum levels was identified significantly more frequently in anti-dsDNA + and anti-dsDNA ± (40.0% and 44.2%, resp.) compared with anti-dsDNA − (21.8%,P=0.005). We did not identify significant differences in the mean ECLAM values before and after modification of anti-dsDNA status (P=0.7).Conclusion. Anti-dsDNA status influences the clinical and immunological features of SLE patients. Nonetheless, it does not appear to affect disease activity.

ObjectiveThe aim of this study was to analyse the 2020 burden of Systemic Lupus Erythematosus (SLE) in Europe, from the patients’ perspective.MethodsIn May 2020, Lupus Europe, the European umbrella patient association for SLE, designed and disseminated a multilingual anonymous online survey to individuals with a self-reported physician’s diagnosis of SLE living in Europe.ResultsData from 4375 SLE survey respondents (95.9% women, median age: 45 (IQR: 36–54) years, 70.7% Caucasians) from 35 European countries were analysed. The median age at SLE diagnosis was 30 years (IQR: 22–40) and the median diagnosis delay was 2 years (IQR: 0–6). The most commonly affected organ-systems included the joints (81.8%) and skin (59.4%), with renal involvement in 30%. Another diagnosis was given before that of SLE in 45.0%, including psychological/mental disorders in 9.1% and fibromyalgia in 5.9%. The median number of symptoms reported was 9 (IQR: 6–11) out of 21, with fatigue most common (85.3%) and most bothersome. The median number of SLE-related medications was 5 (IQR: 3–7), including antimalarials (75%), oral glucocorticoids (52.4%), immunosuppressants (39.8%) and biologics (10.9%). Respondents reported significant impact over their studies, career and emotional/sexual life in 50.7%, 57.9% and 38.2%, respectively. Appropriate access to care was highly variable across countries and care component.ConclusionThis survey underlines the 2020 burden and strong heterogeneity in the care of SLE across Europe, from the patient’s perspective. Altogether, these data may prove crucial to physicians, patients and policy-makers to improve the diagnosis and management of this rare and complex disease.

Background:Systemic lupus erythematosus (SLE) is an autoimmune disease with variable clinical features and a complex physiopathology. In 2019, EULAR and ACR have jointly developed new classification criteria with both high sensitivity and specificity. These criteria have the particularity of including the presence of ANA as an obligatory entry criterion and the existence of clinical and immunological domains with weighted scores.Objectives:To evaluate the performance and characteristics of the ACR/EULAR 2019, SLICC 2012 and ACR 1997 classification criteria in a cohort of SLE patients with longstanding disease.Methods:Descriptive observational study that enrolled a cohort of SLE patients with longstanding disease followed in a tertiary level hospital. Demographic and clinical data were gathered along with the fulfillment of classification criteria. The sensitivity of each classification criteria and the statistically significant associations between criteria fulfillment and clinical and immunological data were calculated. Statistical analyses were performed using the Chi2, T-student and ANOVA tests. Statistical significance was assumed in p values <0.05.Results:A total of 79 patients (88.6% women) with a mean age of 51.8±14 years, disease duration of 15.2±11.5 years and SLEDAI of 2.65±2.1 were included. The sensitivity of the different classification criteria was 51.9% for ACR 1997, 87.3% for SLICC 2012 and 86.1% for ACR/EULAR 2019 (Table 1).Table 1.Sensitivity and average scores.ACR/EULAR 2019SLICC 2012ACR 1997Sensitivity (%)86.187.351.9Average score of patients classified as SLE(±SD)18.6±5.85.3±1.45±0.9Average score of patients NOT classified as SLE(±SD)6.1±2.52.8±0.42.8±0.851.9% of patients met all three classification criteria, 29.1% met SLICC 2012 and ACR/EULAR 2019, 5% only met SLICC 2012 and 3.7% exclusively met ACR/EULAR 2019. 11.4% of patients did not meet any classification criteria and were characterized by having a low SLEDAI (0.6±0.9) and fulfilling only skin domains (alopecia or oral ulcers), antiphospholipid antibodies or hypocomplementemia.Statistically significant associations were found between meeting ACR/EULAR 2019 classification criteria and the presence of low C3 and C4 (p<0.04), DNA (p<0.001), lupus nephritis III-IV (p<0.05) and arthritis (p<0.001), highlighting that all patients with arthritis met these criteria.In the SLICC 2012 evaluation, significant associations were found between meeting these criteria and the presence of arthritis (p<0.01), renal involvement (p<0.04), leukopenia/lymphopenia (p=0.05), DNA (p<0.03) and hypocomplementemia (p=0.02).Fullfilment of ACR 1997 was associated to the presence of malar rash (p<0.001), discoid lupus (p<0.05), photosensitivity (p<0.001) and oral ulcers (p<0.04), as well as arthritis (p<0.001), serositis (p=0.02), renal (p<0.05) and hematologic (p=0.05) involvement.The Kappa concordance coefficient among classification criteria is detailed in Table 2.Table 2.Kappa concordance coefficient.ACR/EULAR 2019 - SLICC 2012ACR/EULAR 2019 - ACR 1997SLICC 2012 - ACR 1997Kappa concordance coefficient0.610.270.30Conclusion:The ACR/EULAR 2019 classification criteria maintain a high sensitivity similar to the SLICC 2012 in SLE patients with longstanding disease, both of which are much higher than ACR 1997. Patients with serological, articular or renal involvement are more likely to meet SLICC 2012 or ACR/EULAR 2019 criteria. It is noteworthy the relevance of dermatological manifestations in ACR1997 classification criteria against the increased weight that a better understanding of SLE physiopathology has provided to analytic and immunological criteria in the subsequent classification criteria.Disclosure of Interests:David Lobo Prat: None declared, Berta Magallares: None declared, Ivan Castellví Consultant of: Boehringer Ingelheim, Actelion, Kern Pharma, Speakers bureau: Boehringer Ingelheim, Actelion, Bristol-Myers Squibb, Roche, HyeSang Park: None declared, Patricia Moya: None declared, Ignasi Gich: None declared, Ana Laiz: None declared, Cesar Díaz-Torné: None declared, Ana Milena Millán Arciniegas: None declared, Susana P.

Background The concomitant presence of two autoimmune diseases – systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) – in the same patient is known as rhupus. We evaluated a group of patients with rhupus to clarify further their clinical, serological and immunogenic features in a multi-centre cohort. In addition, the study aimed to explore the utility of the 2019 European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) SLE classification criteria in our group of patients with rhupus. Methods This was a cross-sectional study. We included rhupus patients from 11 different rheumatology departments, and compared them to SLE and RA patients at a ratio of 2:1. All information was recorded following a pre-established protocol. Results A total of 200 patients were included: 40 rhupus patients and 80 each of SLE and RA patients as controls. Disease duration was similar among SLE and rhupus groups (around 13 years), but the RA group had a significantly lower disease duration. Main clinical manifestations were articular (94.2%), cutaneous (77.5%) and haematological (72.5%). Rhupus patients had articular manifestations similar to those expected in RA. Only 10% of rhupus patients had renal involvement compared with 25% of those with SLE ( p < 0.05), while interstitial lung disease was more common in patients affected by RA. The 2019 EULAR/ACR SLE criteria were met in 92.5% of the rhupus patients and in 96.3% of the SLE cohort ( p > 0.05). Excluding the joint domain, there were no differences between the numbers of patients who met the classification criteria. Conclusion Rhupus patients follow a particular clinical course, with full expression of both SLE and RA in terms of organ involvement, except for a lower prevalence of kidney affection. The new 2019 EULAR/ACR SLE criteria are not useful for differentiating SLE and rhupus patients. A new way of classifying autoimmune diseases is needed to identify overlapping clusters.
