Introduction Although extensively characterized in the outpatient setting, systemic lupus erythematosus (SLE) in the hospitalization wards is still scarcely portrayed, particularly in the perspective of its evolution over the years. Methods Retrospective analysis of SLE patients hospitalized in the Department of Autoimmune Diseases of a university hospital during a 20-year period (1995–2015), describing hospitalization characteristics, causes and predictors of outcome. Results A total of 814 hospitalizations concerning 339 patients were analysed. The main causes of admission were flare (40.2%), infection (19.2%), diagnostic procedures (18.8%) and thrombotic events (5.4%). Therapy with cyclophosphamide (odds ratio (OR) 1.908, p = 0.047) was associated with admission due to infection, while antimalarials displayed a protective effect (OR 0.649, p = 0.024). Nearly 3.9% of patients required admission to an intensive care unit, with associated antiphospholipid syndrome (OR 7.385, p = 0.04) standing as a predicting factor for this outcome. Readmission at 30 days occurred in 5.8% of patients, with thrombocytopenia (OR 6.007, p = 0.002) and renal involvement (OR 3.362, p = 0.032) featuring as predicting factors. Eight patients died, with antiphospholipid syndrome (OR 26.814, p = 0.02) and thrombocytopenia (OR 31.523, p = 0.01) being associated with mortality. There was no significant variation in patients' demographics or admission causes across the 20-year period, except for a decrease in admissions due to thrombotic and musculoskeletal causes. Recently, an increase in the use of mycophenolate mofetil and lower doses of glucocorticoids were noted. Conclusion While demographics of SLE hospitalizations have not markedly changed over the past 20 years, changes in therapy patterns were observed. Thrombocytopenia, antiphospholipid syndrome and renal involvement featured as predictors of poor outcome.

Background:Systemic Lupus Erythematosus (SLE) is a heterogeneous chronic multisystemic disease that has an increased risk of requiring inpatient management with higher morbidity and mortality rates.The most frequent causes of mortality are a high disease activity, infections, and cardiovascular diseases.Objectives:To determine the predictors of mortality in patients diagnosed with SLE.Methods:A longitudinal, descriptive, observational study was performed from March 2017-March 2020 at the University Hospital of the Autonomous University of Nuevo León, México, including patients with a diagnosis of SLE according to the ACR-EULAR 2012/2019 criteria.Descriptive statistics were used for demographic variables. Associations between mortality and clinical variables were determined using binary logistic regression analysis; a p <0.05 was considered statistically significant. The SPSS program version 20 was used.Results:One-hundred and eighty-six patients with SLE diagnosis who fulfilled ACR-EULAR 2012/2019 criteria were included, 161 (86.6%) were women; the mean age was 35.8 (SD 15.41) years. The main chief complaints were dyspnea 31 (16.7%), fever in 28 (15.1%), renal involvement in 21 (11.29%), and arthritis in 19 (10.22%) patients.Of the 186 patients, 34 (18.3%) had a readmission, 13 (7%) required intensive care unit management, 68 (36.6%) had some type of infection and 22 (11.8%) died. Factors associated with mortality are shown in table 1.Patients receiving steroids and immunosuppression previous to hospitalization were 73 (39.2%) and 92 (49.5%) respectively.Conclusion:Infections remain the leading cause of death in SLE patients. Factors that predispose to infections are a chronic use of steroids and immunosuppression as well as high activity of disease.References:[1]Wu X-Y, Yang M, Xie Y-S, Xiao W-G, Lin J, Zhou B, et al.

ABSTRACT. In the course of the antiphospholipid syndrome (APS), the existence of vaso-occlusive lesions capable of affecting numerous organs is now well established. The renal involvement attributable to primary APS, APS nephropathy (APSN), corresponds to vaso-occlusive lesions of the intrarenal vessels, associating side-by-side, acute thromboses with chronic arterial and arteriolar lesions, leading to zones of cortical ischemic atrophy. A retrospective study of 114 lupus patients undergoing renal biopsy was undertaken to determine the following: (1) if APSN can be found in the course of systemic lupus erythematosus (SLE); (2) if certain clinical and biologic factors can permit the prediction of the presence of APSN; and (3) if APSN is a superadded renal morbidity factor in lupus patients. This study shows the following: (1) APSN occurs in SLE (32% of patients with renal biopsies) in addition to, and independently of, lupus nephritis; (2) APSN is statistically associated with lupus anticoagulant but not with anticardiolipin antibodies; (3) APSN is associated with extrarenal APS, mainly arterial thromboses and obstetrical fetal loss, but not with the venous thromboses of APS; (4) APSN is an independent risk factor, over and above lupus nephritis, that contributes to an elevated prevalence of hypertension, elevated serum creatinine, and increased interstitial fibrosis. Thus, it seems likely that, because of its associations with hypertension, elevated serum creatinine, and increased interstitial fibrosis, APSN may worsen the prognosis in these patients. APSN may also have therapeutic significance in that its recognition should permit a better balance between immunosuppressor and antithrombotic and/or vasoprotective therapy. Finally, this study suggests that APSN should be considered as an element to be included in the classification criteria of APS.

The association between thrombotic events and primary or secondary antiphospholipid/anticardiolipin syndrome is now well recognized. A spectrum of renal involvement ranging from glomerular thrombosis to renal infarction has been described. A case of systemic lupus erythematosus with immunoglobulin G and M antiphospholipid/anticardiolipin antibodies is reported. The patient developed catastrophic thrombosis in multiple organs, and glomerular thrombosis was documented by renal biopsy. The patient had an acquired antithrombin III deficiency, and the combination of secondary antiphospholipid syndrome with accompanying antithrombin III deficiency predisposed to thrombosis. Several mechanisms by which antiphospholipid/anticardiolipin antibodies cause thrombosis have been proposed and are briefly reviewed.

Introduction Disease features and laboratory abnormalities differ among adult-onset and childhood-onset systemic lupus erythematosus (aSLE and cSLE). Socioeconomic status both independent of, and in combination with, ethnicity influences the disease phenotype and outcome. Objective To compare the various disease features among patients with cSLE and aSLE in a limited monetary income Egyptian cohort attending a large free-of-charge university hospital. Patients and methods: Retrospective analysis of the medical records of 714 SLE patients attending Cairo University Hospitals from January 2000 to December 2019. Of them 602 (400 with aSLE and 202 with cSLE) were enrolled in the study. Results The mean age of disease onset was 28.27 ± 10.55 among aSLE patients compared to 12.88 ± 4.26 years among cSLE patients. Disease duration was 12.03 ± 5.05 and 4.14 ± 3.18 years in aSLE and cSLE, respectively. Female to male ratio was 15:1 among patients with aSLE, as compared to 2.67:1 among cSLE (<0.001). Arthritis (69%), oral ulcers (48.5%), neuropsychiatric (18.3%) and thrombotic manifestations of antiphospholipid syndrome (12%) were significantly more frequent in aSLE. On the other hand, renal (67.8%), serositis (49.6%), fever (49%), lymphopenia (40.6%), hemolytic anemia (38.6%), and discoid lupus (13.4%) were significantly more frequent in cSLE. Weight loss, malar rash, photosensitivity, thrombocytopenia, leucopenia and lymphadenopathy were not significantly different between the two groups. Hypocomplementemia, proteinuria, urinary sediments, hematuria were significantly more frequent in cSLE. For those patients with renal involvement, who underwent renal biopsy (58.3% in aSLE and 63.5% in cSLE), there was no significant difference with regard to the different histopathological classes. Anti-Smith, anti-cardiolipin antibodies and rheumatoid factor were significantly more frequent among aSLE patients, while anti-La antibodies were more frequent among cSLE patients. Conclusion Arthritis was the most common clinical manifestation over time in aSLE compared to renal involvement in cSLE. Renal disease tends to be more active in cSLE. The differences in disease manifestations between this cohort and other studies can be attributed to the ethnic and socioeconomic disparities.

Background: Sudden sensorineural hearing loss (SSNHL) is defined as a sudden loss of hearing, usually unilateral, of more than 30 dB in 3 contiguous frequencies of the tonal audiometry. SSNHL estimates an incidence ranging from 5 to 20 per 100.000 people per year. In approximately 75% of cases, a cause cannot be identified. However, it could be a clinical manifestation of Systemic lupus erythematosus (SLE) and Antiphospholipid Syndrome (APS). Objective: This review will focus on the clinical presentation, diagnosis, and management of the SLE and APS associated SSNHL. Methods: We searched in PubMed, Scopus, Lilacs, and Cochrane reviewing reports of Sudden sensorineural hearing loss in SLE and/or APS. Articles written in English and Spanish, and were available in full text, were included. Results: In patients with SLE, bilateral involvement was frequent. Antiphospholipid antibodies were positive in the majority of the patients. Corticosteroids were the mainstay of the treatment. The auditory prognosis was poor with total hearing loss recovery reached in only 22% of patients. : On the other hand, most of the patients with SSNHL and APS were males and presented associated symptoms such as vertigo, tinnitus and/or headache, 75% had bilateral disease. Lupus anticoagulant and aCL were found in equal proportions, all patients were anticoagulated, and aspirin was associated in 25% of the cases. Complete resolution or improvement of symptoms was observed in 25% of the patients. Conclusion: Sudden sensorineural hearing loss, can be a clinical feature of SLE and APS. Treating physicians should be aware of this devastating complication, especially when bilateral involvement occurs.

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.

Background:Recently developed EULAR/ACR classification criteria for systemic lupus erythematosus (SLE) have important differences compared to the 2012 Systemic Lupus International Collaborating Clinics (SLICC) SLE classification criteria and the revised 1997 American College of Rheumatology (ACR) criteria: The obligatory entry criterion of antinuclear antibody (ANA) positivity is introduced and a “weighted” approach is used1. Sensitivity and specificity of these three criteria have been debated and may vary in different populations and clinical settings.Objectives:We aim to compare the performances of three criteria sets/rules in a large cohort of patients and relevant diseased controls from a reference center with dedicated clinics for SLE and other autoimmune/inflammatory connective tissue diseases from Turkey.Methods:We reviewed the medical records of SLE patients and diseased controls for clinical and laboratory features relevant to all sets of criteria. Criteria sets/rules were analysed based on sensitivity, positive predictive value, specificity and negative predictive value, using clinical diagnosis with at least 6 months of follow-up as the gold standard. A subgroup analysis was performed in ANA positive patients for both SLE patients and diseased controls. SLE patients that did not fulfil 2012 SLICC criteria and 2019 EULAR/ACR criteria and diseased controls that fulfilled these criteria were evaluated.Results:A total of 392 SLE patients and 294 non-SLE diseased controls (48 undifferentiated connective tissue disease, 51 Sjögren’s syndrome, 43 idiopathic inflammatory myopathy, 50 systemic sclerosis, 52 primary antiphospholipid syndrome, 15 rheumatoid arthritis, 15 psoriatic arthritis and 20 ANCA associated vasculitis) were included into the study. Hundred and fourteen patients (16.6%) were ANA negative.Sensitivity was more than 90% for 2012 SLICC criteria and 2019 EULAR/ACR criteria and positive predictive value was more than 90% for all three criteria (Table 1). Specificity was the highest for 1997 ACR criteria. Negative predictive value was 76.9% for ACR criteria, 88.4% for SLICC criteria and 91.7% for EULAR/ACR criteria.In only ANA positive patients, sensitivity was 79.6% for 1997 ACR criteria, 92.2% for 2012 SLICC criteria and 96.1% for 2019 EULAR/ACR criteria. Specificity was 92.6% for ACR criteria, 87.8% for SLICC criteria 85.2% for EULAR/ACR criteria.Eleven clinically diagnosed SLE patients had insufficient number of items for both 2012 SLICC and 2019 EULAR/ACR criteria. Both criteria were fulfilled by 16 diseased controls: 9 with Sjögren’s syndrome, 5 with antiphospholipid syndrome, one with dermatomyositis and one with systemic sclerosis.Table 1.Sensitivity, positive predictive value, specificity and negative predictive value of 1997 ACR, 2012 SLICC and 2019 EULAR/ACR classification criteriaSLE (+)SLE (-)Sensitivity (%)Positive Predictive Value (%)Specificity (%)Negative Predictive Value (%)1997 ACR(+) 308(-) 841527978.695.494.976.92012 SLICC(+) 357(-) 352626891.193.291.288.42019 EULAR/ACR(+) 368(-) 242826693.892.990.591.7Conclusion:In this cohort, although all three criteria have sufficient specificity, sensitivity and negative predictive value of 1997 ACR criteria are the lowest. Overall, 2019 EULAR/ACR and 2012 SLICC criteria have a comparable performance, but if only ANA positive cases and controls are analysed, the specificity of both criteria decrease to less than 90%. Some SLE patients with a clinical diagnosis lacked sufficient number of criteria. Mostly, patients with Sjögren’s syndrome or antiphospholipid syndrome are prone to misclassification by both recent criteria.References:[1]Aringer M, Costenbader K, Daikh D, et al. 2019 European League Against Rheumatism/American College of Rheumatology classification criteria for systemic lupus erythematosus.
