Objective.To determine whether there is any seasonal variation in the activity of systemic lupus erythematosus (SLE) overall and by individual organs.Methods.The study group comprised 2102 patients with SLE who were followed in a prospective longitudinal cohort study. In this cohort, 92.3% of the patients were women. The mean ± SD age of the patients was 47.9 ± 13.9 years, 56.3% were white, 37.1% were African American, and 3.1% were Asian. Global disease activity was recorded by the Safety of Estrogens in Lupus Erythematosus National Assessment – Systemic Lupus Erythematosus Disease Activity Index (SELENA-SLEDAI) and the physician’s global assessment. Activity of each organ was also recorded using SLEDAI terms and a visual analog scale (VAS; 0 to 3).Results.There was significant seasonal variation in photosensitive rash (p < 0.0001), which was more frequent in the spring and summer months (p < 0.0001). There was significantly more arthritis activity in spring and summer, as measured by both SELENA-SLEDAI (p = 0.0057) and the joint VAS (p = 0.0047). A decrease in renal activity was found in the summer months compared to the rest of the year (p = 0.0397). Serositis recorded by VAS had higher activity from August to October (p = 0.0392). Anti-dsDNA levels were significantly higher during October and November (p < 0.0001). There was significant seasonal variation in antiphospholipid antibody levels (p < 0.0001) and lupus anticoagulant (p = 0.0003). We found a significant variation in activity through the year in global disease activity as measured by SELENA-SLEDAI (p = 0.048).Conclusion.In the Hopkins Lupus Cohort, skin and joint activity is increased during the spring and summer, but other organs have different patterns. These seasonal variations likely reflect environmental factors that influence disease activity, including ultraviolet light and infections.

We have explored the relationship between possible hemostatic changes and clinical manifestation of the systemic lupus erythematosus (SLE) as a function of greater or lesser disease activity according to Systemic Lupus Erythematosus Disease Activity Index-2000 (SLEDAI-2K) criteria. Endothelial injury and hypercoagulability were investigated in patients with SLE by measuring thrombomodulin (TM), D-dimer (DDi) and thrombin generation (TG) potential. A total of 90 participants were distributed into three groups: 1) women with SLE presenting with low disease activity (laSLE) (SLEDAI-2K ≤ 4), 2) women with SLE presenting with moderate to high disease activity (mhaSLE) (SLEDAI-2K > 4), and 3) a control group comprising healthy women. Levels of TM and DDi were higher both in the laSLE and mhaSLE groups compared to controls and in mhaSLE compared to the laSLE group. With respect to TG assay, lagtime and endogen thrombin potential, low concentrations of tissue factor provided the best results for discrimination among groups. Analysis of these data allow us to conclude that TM, DDi and TG are potentially useful markers for discriminating patients with very active from those with lower active disease. Higher SLE activity may cause endothelial injury, resulting in higher TG and consequently a hypercoagulability state underlying the picture of thrombosis common in this inflammatory disease.

Abstract Background Systemic lupus erythematosus (SLE) is an independent risk factor for cardiovascular events. The present study determined the prevalence of subclinical atherosclerosis in childhood-onset SLE using the carotid intima-media thickness (CIMT) measurement and investigated associations between traditional and nontraditional risk factors for atherosclerosis, such as medications, SLE Disease Activity Index - SLEDAI-2 K and SLICC-ACR damage index and CIMT. Methods Cross-sectional prospective study between 2017 and 2018. CIMT was assessed by ultrasonography. Data were collected by chart review, nutritional evaluation and laboratory tests and analyzed by Fisher, Wilcoxon-Mann-Whitney tests, multiple linear and log binomial regression. Results Twenty-eight patients (mean age 13.9 years, SD 3) were enrolled. The prevalence of subclinical atherosclerosis was 32% (95% CI 14.8, 49.4). The mean CIMT was 0.43 ± 0.035 mm. The most common traditional risk factors observed were dyslipidemia (82.1%), uncontrolled hypertension (14.2%), obesity (14.3%), and poor diet (78.6%). Uncontrolled hypertension (p = 0.04), proteinuria (p = 0.02), estimated glomerular filtration rate < 75 ml /min/1.73 m2 (p = 0.02) and SLEDAI-2 K > 5 (P = 0.04) were associated with subclinical atherosclerosis. SLEDAI-2 K > 5 maintained association with CIMT after adjusting for control variables. Conclusion Subclinical atherosclerosis is frequently observed in cSLE, mainly in patients with moderate to severe disease activity.

Objective This study aimed to assess IL-24 levels and their association with clinical manifestations in patients with systemic lupus erythematosus (SLE). Methods There were 75 patients with SLE and 58 healthy controls recruited in this study. Serum levels of IL-24 were measured by enzyme-linked immunosorbent assays, and mRNA levels of IL-24 were tested by quantitative real-time polymerase chain reaction . The area under the curve of the receiver operating characteristic (ROC) curve was used for diagnostic ability of the inflammatory cytokine. Results Serum IL-24 levels were significantly higher in SLE patients than that in healthy controls. SLE patients with nephritis had higher IL-24 levels than those without nephritis. Active SLE patients showed higher expression of IL-24 as compared to less active disease patients. The mRNA levels of IL-24 were much higher in SLE patients. Correlation analysis showed significant correlation between serum IL-24 levels and SLE disease activity index. In addition, ROC analysis may suggest good ability of serum IL-24 in differentiating SLE. Conclusion The inflammatory cytokine correlated with SLE disease activity, and may be involved in this disease pathogenesis.

Background and Aim: The aim of this study was to compare the correlation of a recently developed systemic lupus erythematosus disease activity score (SLE-DAS) with the SLE disease activity index 2000 (SLEDAI-2K) with the Lupus Quality of Life questionnaire (LupusQoL) in Taiwanese patients with SLE. Methods: A cross-sectional study was conducted in a regional teaching hospital in Taiwan from April to August 2019. Adult patients with a clinician-confirmed diagnosis of SLE based on the 1997 American College of Rheumatology revised criteria or the 2012 Systemic Lupus International Collaborating Clinics Classification Criteria were recruited. SLE disease activity was measured with both SLEDAI-2K and SLE-DAS. Disease-specific quality of life was assessed using the LupusQoL. Results: Of the 333 patients with SLE in this study, 90.4% were female and 40% were between the ages of 20 and 39 years. The median SLEDAI-2K score was 4.00 (interquartile range [IQR] 2.00–7.50) and the median SLE-DAS score was 2.08 (IQR 1.12–8.24) in our patients with SLE. After adjusting for sex and age intervals, both SLEDAI-2k and SLE-DAS were significantly and inversely associated with all eight domains of LupusQoL. The magnitudes of the mean absolute error, root mean square error, Akaike Information Criterion, Bayesian Information Criterion, and coefficient of determination were comparable between SLEDAI-2K and SLE-DAS. Conclusions: There were no clear differences in the use of SLE-DAS over SLEDAI-2K in assessing HRQoL in patients with SLE. We suggest that, in this aspect, both SLEDAI-2K and SLE-DAS are effective tools for measuring disease activity in patients with SLE.

Objective.To evaluate the performance of the Systemic Lupus Erythematosus (SLE) Responder Index (SRI) when the SLE Disease Activity Index 2000 (SLEDAI-2K) is substituted with SLEDAI-2K Responder Index-50 (SRI-50), a valid and reliable index of disease activity improvement. Also, to determine whether the SRI-50 will enhance the ability of SRI in detecting responders.Methods.Our study was conducted on patients who attended the Lupus Clinic from September 2009 to September 2010. SLEDAI-2K, SRI-50, the British Isles Lupus Assessment Group measure, and the Physician’s Global Assessment were determined initially and at followup. SRI was determined at the followup visit according to its original definition using the SLEDAI-2K score and by substituting SLEDAI-2K with SRI-50.Results.A total of 117 patients with SLEDAI-2K ≥ 4 at baseline were studied. Patients had 1 followup visit over a 3-month period. Twenty-nine percent of patients met the original definition of SRI and 35% of patients met the definition of SRI when SLEDAI-2K was substituted with SRI-50. The use of SRI-50 allowed determination of significant improvement in 7 additional patients. This improvement could not be discerned with the use of SLEDAI-2K as a component of SRI. At followup visits that showed improvement, SRI-50 scores decreased to a greater extent than SLEDAI-2K scores (p < 0.0001).Conclusion.SRI-50 enhances the ability of SRI to identify patients with clinically important improvement in disease activity. SRI-50 was superior to SLEDAI-2K in detecting partial clinical improvement, ≥ 50%, between visits. These properties of the SRI-50 enable it to be used as an independent outcome measure of improvement or as a component of SRI in clinical trials.

Background:Systemic lupus erythematosus is an autoimmune disease with a major impact on patient’s quality of life.Objectives:To evaluate patient’s attitude toward early disease and factors that influence it.Methods:Performed case-control study included SLE patients that fulfilled SLICC, 2012 classification criteria. The research included two groups of patients: early SLE – 1stgroup (disease duration ≤24 months) and non-early SLE – 2ndgroup control (disease duration >24 months). The pattern of the disease activity was assessed by patient global assessment (PGA), Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) and Systemic Lupus Activity Measure (SLAM), for SLE activity, SLICC/ACR Damage Index (DI) for disease irreversible changes and SF-8 for the Quality of Life (QoL).Results:A total of 101 SLE patients with 34 in the 1stgroup (early SLE) and 67 in the 2ndgroup (non-early SLE) was analyzed. The disease activity showed high disease activity in both groups by SLEDAI (7,02±4,16 and 6,26±4,43 points, p>0,05) and SLAM (7,47±4,40 and 7,31±4,10 points, p>0,05) such as (46,97±19,39 vs 47,98±22,41 points). The QoL was appreciated as low, by both components (mental and physical), in groups. The damage index was higher in the 2nd group (0,23±0,43 and 1,07±1,29, p<0,001), which can be explained by the development of irreversible changes with the increase of disease duration.The PGA in early SLE was influenced by subjective symptoms contained in SLAM index (r=0,48, p<0,05), such as fatigue and depression, and the level of the quality of life (r=0,65, p<0,001). Meantime, PGA in patients with longer disease duration (>2 years), was influenced by the presence of organ damage by SLICC/ACR DI (0,23, p<0,05) and objective findings of the disease activity contained in SLEDAI (r=0,33, p<0,005) and SLAM (0,44, p<0,001).Conclusion:The disease recognition in patients with early SLE was determined by subjective and psycho-emotional signs, while in patients with longer disease duration it was influenced by organ damage and complications.References:no referencesDisclosure of Interests:None declared

Objective.Adjusted mean Systemic Lupus Erythematosus Disease Activity Index (SLEDAI; AMS) measures lupus disease activity over time. Our aim was to determine optimal visit frequency for calculating AMS.Methods.Patients followed monthly for 12 consecutive visits were included. AMS was calculated using all of the SLEDAI 2000 (AMSGOLD using all 12 visits), only quarterly visits (AMS3, using visits 3 months apart), semiannual visits (AMS6, using first, middle, and last visits only), and annual visits (AMS12, using only the first and last visits). Comparisons of AMS3, AMS6, and AMS12 with AMSGOLD are made using descriptive statistics.Results.Seventy-eight patients were included (92% women, mean age at SLE diagnosis 30.1 yrs and at study start 46.2 yrs). The mean (SD) AMSGOLD for the entire year was 2.05 (1.66), for AMS3 1.99 (1.65), for AMS6 2.12 (1.87), and for AMS12 2.08 (1.83). Mean (SD) of the absolute differences with AMSGOLD: for AMS3 0.29 (0.33), for AMS6 0.45 (0.59), and for AMS12 0.61 (0.58). Differences that were < 0.5 were considered minimal while those ≥ 1 were deemed important. Comparing AMSGOLD to AMS3, 82% of the differences were minimal and 3% were important. When comparing to AMS6, 68% were minimal and 10% were important, while comparing to AMS12, 50% were minimal and 21% were important.Conclusion.Usual clinic visits occurring quarterly offer a good estimation of disease activity over a 1-year period and are preferred over semiannual and annual visits.

Objective.To determine whether serum albumin reflects disease activity in patients with systemic lupus erythematosus (SLE) with and without nephritis (LN, LNN), and whether serum albumin could be a surrogate marker of SLE disease activity overall. There is currently no clinical “gold standard” in the assessment of disease activity in SLE.Methods.Patients with ≥ 3 clinic visits within a maximum followup period of 10 years were selected from the University of Toronto Lupus Clinic database. Subjects were divided into 3 groups: LN-B, those with nephritis defined by histological findings on renal biopsies; LN-L, those with nephritis defined by laboratory abnormalities in the absence of biopsy; and LNN, those without nephritis. In a subanalysis, the renal groups were further stratified by proteinuria status. The associations of SLE-Disease Activity Index (SLEDAI-2K) with serum albumin and dsDNA were examined using the mixed model regression analysis.Results.A total of 1078 patients were studied: 89.1% female, 71.5% white, mean age 33.6 (SD 12.6) years, and with median baseline SLEDAI-2K of 8. Serum albumin was more significantly associated with SLEDAI in LN-B and LN-L. The association was also present but weaker in the LNN group. In all LN, the associations between serum albumin and SLEDAI-2K were stronger in those with proteinuria.Conclusion.In patients with SLE, higher SLEDAI was associated with lower serum albumin levels.

Abstract Background Pediatric Systemic Lupus Erythematosus (pSLE) is a chronic mutisystemic autoimmune disease with complex clinical manifestations whose diagnosis is not always easy and the course is generally severe and the treatment is not very well codified and often extrapolated from that of adults. This study aims to describe the clinical, immunological, therapeutic characteristics and short outcome of systemic lupus erythematosus in Algerian children. Methods This was a prospective, multicentre and descriptive study 36 months (January 2015 - December 2018) at the department of Pediatrics of University Hospital Nefissa Hamoud ex Parnet Algiers. Children less than16 years of age fulfilling the American College of Rheumatology SLE criteria were included. Disease activity estimated by Systemic Lupus Erythematosus Disease Activity index (SLEDAI) whose use has been validated in children and damage index based on Systemic Lupus International Collaborating Clinics (SLICC) score were determined. Results Eighty-three (83) patients were studied. Female: male ratio was1:49. Mean ages at lupus onset and diagnosis were respectively: 10, 12 ± 3, 88 and 11, 3 ± 3, 62 years. All patients had skin involvement while constitutional signs including fever and asthenia were observed in (98.8%). Rheumatological, renal, neuropsychiatric, cardiac, hepato-digestive, pleuropulmonary and ocular disorders were observed respectively: 65, 1%, 44, 6%, 41%, 27, 7%, 41%, 19, 3% and 7, 2%. All patients were positive for antinuclear antibodies. Anti-double-stranded DNA (75%) was the most frequently observed autoantibody profile. Antiphospholipid antibody positivity was noted in 52% whereas hypocomplementemia in fractions C3, C4 was observed in 55% and 56% respectively. In our study, the severe forms were more frequent (83%) than the mild ones (17%) with a significant difference (P = &lt; 10–6). Overall, the mean SLEDAI at disease onset was 22.11 ± 11.87 with high activity ≥ 20 in 59% of cases. The mean damage score was 1.8 ± 2.045 (interquartile range 0–8). Among induction drugs, oral corticosteroids were the most frequently used (92%), and in a third of cases intravenously at high doses in combination with immunosuppressive therapy. In induction therapy, cyclophosphamide (CYC) was the most used drug (23%) compared with mycophenolate mofetil (MMF) (14%). Unlike the maintenance phase where MMF observed an increase (28%) vs (8%) CYC. The use of MMF was correlated with severe lupus nephritis with a significantly effective difference in the decrease in SLEDAI (P = 0.0001). The use of hydroxychloroquine (HCQ) was observed in 81% in induction and 89% in maintenance treatment. The correlation of HCQ use with survival was significantly positive (P = 0.04). Indeed, adherence to treatments and essentially HCQ was a protective factor, its odds ratio is &lt; 1 with a significant p-value, [OR 0.016 95% CI (0.001–0.353)]. Mortality was estimated at 11%. Multivariable regression analysis showed that the neurological involvement (odds ratio = 6,093 95% confidence interval ((1,1 8 0 ∼ 31 446)) and macrophage activation syndrome were associated with a high risk of mortality. Conclusion we report a series of pSLE characterized by great clinical and biological heterogeneity. It follows a severe course of the disease with high disease activity at the diagnosis and therefore leads to high morbidity and mortality. However, these results must be confirmed by other pediatric studies which could form the basis of a diagnostic and therapeutic approach more adapted for children.
