Introduction We aimed to investigate risk factors for fatigue in patients with systemic lupus erythematosus (SLE) and neuropsychiatric symptoms in order to identify potential interventional strategies. Methods Patients visiting the neuropsychiatric SLE (NPSLE) clinic of the Leiden University Medical Center between 2007–2019 were included. In a multidisciplinary consensus meeting, SLE patients were classified as having neuropsychiatric symptoms of inflammatory origin (inflammatory phenotype) or other origin (non-inflammatory phenotype). Fatigue was assessed with the SF-36 vitality domain (VT) since 2007 and the multidimensional fatigue inventory (MFI) and visual analogue scale (VAS) since 2011. Patients with a score on the SF-36 VT ≥1 standard deviation (SD) away from the mean of age-related controls of the general population were classified as fatigued; patients ≥2 SD away were classified as extremely fatigued. Disease activity was measured using the SLE disease activity index-2000. The influence of the presence of an inflammatory phenotype, disease activity and symptoms of depression and anxiety as measured by the hospital anxiety and depression scale (HADS) was analyzed using multiple regression analyses corrected for age, sex and education. Results 348 out of 371 eligible patients filled in questionnaires and were included in this study . The majority was female (87%) and the mean age was 43 ± 14 years. 72 patients (21%) had neuropsychiatric symptoms of an inflammatory origin. Fatigue was present in 78% of all patients and extreme fatigue was present in 50% of patients with an inflammatory phenotype vs 46% in the non-inflammatory phenotype. Fatigue was similar in patients with an inflammatory phenotype compared to patients with a non-inflammatory phenotype on the SF-36 VT (β: 0.8 (95% CI −4.8; 6.1) and there was less fatigue in patients with an inflammatory phenotype on the MFI and VAS (β: −3.7 (95% CI: −6.9; −0.5) and β: −1.0 (95% CI −1.6; −0.3)). There was no association between disease activity and fatigue, but symptoms of anxiety and depression (HADS) associated strongly with all fatigue measurements. Conclusion This study suggests that intervention strategies to target fatigue in (NP)SLE patients may need to focus on symptoms of anxiety and depression rather than immunosuppressive treatment.

Objective Hypomethylation of CD40-ligand (CD40L) in T-cells is associated with increased disease activity in systemic lupus erythematosus (SLE). We therefore investigated possible associations of dietary methyl donors and products with CD40L methylation status in SLE. Methods Food frequency questionnaires were employed to calculate methyl donor micronutrients in 61 female SLE patients (age 45.7 ± 12.0 years, disease duration 16.2 ± 8.4 years) and compared to methylation levels of previously identified key DNA methylation sites (CpG17 and CpG22) within CD40L promotor of T-cells using quantitative DNA methylation analysis on the EpiTYPER mass spectrometry platform. Disease activity was assessed by SLE Disease Activity Index (SLEDAI). Linear regression modelling was used. P values were adjusted according to Benjamini & Hochberg. Results Amongst the micronutrients assessed (g per day), methionine and cysteine were associated with methylation of CpG17 (β = 5.0 (95%CI: 0.6-9.4), p = 0.04; and β = 2.4 (0.6-4.1), p = 0.02, respectively). Methionine, choline, and cysteine were additionally associated with the mean methylation of the entire CD40L (β = 9.5 (1.0-18.0), p = 0.04; β = 1.6 (0.4-3.0), p = 0.04; and β = 4.3 (0.9-7.7), p = 0.02, respectively). Associations of the SLEDAI with hypomethylation were confirmed for CpG17 (β=-32.6 (-60.6 to -4.6), p = 0.04) and CpG22 (β=-38.3 (-61.2 to -15.4), p = 0.004), but not the mean methylation of CD40L. Dietary products with the highest impact on methylation included meat, ice cream, white bread, and cooked potatoes. Conclusions Dietary methyl donors may influence DNA methylation levels and thereby disease activity in SLE.

Background:Fatigue is commonly described in chronic illnesses, especially auto-immune disorders such as systemic lupus erythematosus (SLE).Objectives:We aim to study the prevalence of fatigue in SLE patients with NP symptoms and compare fatigue in SLE patients with NP symptoms attributed to major organ involvement due to SLE (NPSLE) with SLE patients with NP symptoms not caused by major nervous system involvement (non-NPSLE).Methods:All patients visiting the tertiary referral center for NPSLE in the LUMC between 2007-2019 with the clinical diagnosis of SLE and age >18 years that signed informed consent were included in this study. Patients underwent a standardized multidisciplinary assessment, including two questionnaires: SF-36 (2007-2019) and multidimensional fatigue index (MFI, 2011-2019). Patients were classified as NPSLE in this study if NP symptoms were attributed to SLE and immunosuppressive or anticoagulant therapy was initiated, otherwise patients were classified as non-NPSLE. The vitality (VT) domain of the SF-36 domain was used to assess fatigue, which generates a score from 0-100, 100 representing the complete absence of fatigue. Patients with a score more than 1 standard deviation (SD) removed from age-related controls of the Dutch general population were classified as fatigued; patients more than 2 SD removed were classified as extremely fatigued1. The MFI was also used, which consists of 5 subdomain scores between 0-20, leading to a total score between 0-100, 100 representing the most extreme fatigue. All scores are presented as mean and standard deviation.Results:373 patients fulfilled the inclusion criteria and SF-36 questionnaires of 328 patients were available (88%). The majority of these patients was female (87%) and 98 were classified as NPSLE (30%). In NPSLE patients, average age was 41 ± 13 years and in non-NPSLE the average age was 45 ± 14 years. The average score of the SF-36 vitality domain was 36.0 ± 20.7 in NPSLE vs 33.9 ± 18.8. in non-NPSLE. Overall, 73.5% of the patients were fatigued and 46.9% extremely fatigued in NPSLE vs 77.8% fatigued and 45.7% extremely fatigued in non-NPSLE.The MFI questionnaire and VAS score were available for 222 patients, of which 65 patients were classified as NPSLE (29.3%). Table 1 depicts the scores of NPSLE and non-NPSLE patients on the MFI subdomains and the VAS score.Table.Patient characteristics at registry entry.NPSLE(N = 65)Non-NPSLE (N = 157)MFI(mean, sd)General Fatigue10.8 (1.8)11.1 (1.5)Physical Fatigue11.4 (2.4)12.3 (1.9)Reduced Activity9.6 (2.9)10.7 (2.2)Reduced Motivation10.7 (2.6)11.1 (1.9)Mental Fatigue9.5 (3.0)9.8 (2.7)Total score51.8 (9.9)54.9 (6.9)SF-36 Vitality (mean, sd)35 (20.7)32.7 (18.2)Conclusion:Nearly half of patients with SLE and NP symptoms are as extremely fatigued as only 2.5% of the general Dutch population.

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.

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.

We aimed to validate the reliability of the Medical Outcomes Study Short Form-36 (SF-36) among Japanese patients with systemic lupus erythematosus (SLE). Japanese patients with SLE ( n = 233) completed the SF-36 and other related demographic questionnaires, and physicians simultaneously completed the SLE Disease Activity Index 2000 (SLEDAI-2K) and the Systemic Lupus International Collaborating Clinics Damage Index (SDI). Patients were prospectively followed for a repeat assessment the following year. The SF-36 subscales demonstrated acceptable internal consistency (Cronbach’s α of 0.85–0.89), and an overall good test–retest reliability (intraclass correlation coefficient >0.70). The average baseline SF-36 subscale/summary scores except for “bodily pain” were significantly lower than those of the Japanese general population ( p < 0.05). The SDI showed an inverse correlation with the SF-36 subscale/summary scores except for “vitality” and “mental component summary” at baseline, whereas the SLEDAI-2K did not. In the second year, “social functioning” and “mental component summary” of the SF-36 deteriorated among patients whose SDI or SLEDAI-2K score increased (effect sizes < −0.20). In conclusion, the SF-36 demonstrated acceptable reliability among Japanese patients with SLE. Health-related quality of life measured by the SF-36 was reduced in Japanese patients with SLE and associated with disease damage, rather than disease activity.

AimsTo determine whether the proportion of time systemic lupus erythematosus patients achieve remission/low disease activity state (LDAS) is associated with a better quality of life (QoL).Patients and methodsPatients from a well-established multiethnic, multicentre US cohort were included: remission: Systemic Lupus Activity Measure (SLAM) score=0, prednisone≤5 mg/day and no immunosuppressants); LDAS not in remission, SLAM score≤3, prednisone≤7.5 mg/day, no immunosuppressants; the combined proportion of time patients were in these states was the independent variable. The endpoints were the Physical and Mental Components Summary measures (PCS and MCS, respectively) and the individual subscales of the Short Form (SF)-36 at the last visit. Linear regression was used to estimate the association between the proportion of follow-up time in remission/LDAS and the SF-36 measures with and without adjustment for possible confounders.ResultsFour hundred and eighty-three patients were included. The per cent of time on remission/LDAS was associated with better QoL after adjusting for potential confounders; for the PCS the parameter estimate was 9.47 (p<0.0001), for the MCS 5.89 (p=0.0027), and for the subscales they ranged between 7.51 (p=0.0495) for mental health and 31.79 (p<0.0001) for role physical.ConclusionsThe per cent of time lupus patients stay on remission/LDAS is associated with a better QoL as measured by SF-36.

Objective To evaluate the reliability, validity, feasibility and psychometric performance of the Lupus Impact Tracker (LIT) as a patient reported outcome (PRO) measure tool in pediatric systemic lupus erythematosus (pSLE). Methods This is a prospective, observational, pilot study where patients aged between 12 and 25 years, fulfilling the 1997 ACR classification criteria for SLE, were enrolled. Over 3 consecutive, routine, clinical visits, the patients completed the LIT alongside the Patient-Reported Outcomes Measurement Information System-Short Forms (PROMIS-SFs), Childhood Health Assessment Questionnaire (CHAQ). Rheumatologists completed the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) and the Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC-ACR) Damage Index. Demographic, clinical and laboratory data were also collected. Results Of 46 patients enrolled, 38 patients completed 2 visits and 31 completed all 3 visits. Seventy-eight percent were female, 33% African American, 28% Asian, 15% Caucasian and 17% Hispanic. The mean (SD) age was 17.2 (2.7) years, with a mean (SD) disease duration of 4.6 (3.1) years. The mean (SD) SLEDAI-2K at enrollment was 3.54 (2.96). In the 38 patients who completed two or more visits, intra-class correlation coefficient and Cronbach alpha were calculated to be 0.70 and 0.91 respectively, signifying good reliability of LIT. The LIT showed positive correlation with CHAQ-Disability Index and majority of the PROMIS-SFs parameters. Construct validity was established against clinical disease activity (SLEDAI-2K). Conclusion The preliminary results indicate that the LIT is a reliable and valid instrument to capture PRO in p-SLE. Prospective validation with a larger, multicenter cohort is the next step.

Abstract Introduction The cardiovascular system is affected in systemic lupus erythematosus (SLE) by the disease itself, the state of chronic inflammation and also by the side effects of the treatment given. Purpose To find the burden of cardiovascular involvement in SLE, to correlate cardiovascular manifestation with SLE disease activity (SLEDAI-2K) and damage [SLICC/ACR Damage Index (SDI)]. Methods Seventy-five consecutive SLE patients fulfilling SLICC criteria, aged between 15–55 years, with disease duration of <5 years, admitted to rheumatology ward, were included. Overlap syndromes, past history of cardiac disease, end stage renal disease, chronic liver disease and type 2 diabetes mellitus were excluded. Clinical examination, fasting serum lipid profile, electrocardiogram, 2D-Echocardiography, carotid intima media thickness (CIMT) and serum Troponin-I were used to assess the cardiovascular status of patients. Results In this cross-sectional study exploring cardiovascular disease burden in a cohort of SLE patients within 5 years of disease, we found the mean age of patients was 28.5±7.9 years with a male: female ratio of 1:14. Cardiovascular involvement was detected in 52% of patients. Raised systolic BP was detected in 42% and raised diastolic BP in 28% patients. ECG revealed sinus tachycardia in 32%. 2D-echocardiography revealed pericardial effusion in 14.66%, mitral valve involvement in 10.66% (7 had mitral regurgitation and one had mitral sclerosis). PAH and TR were observed in 5.33% and 6.66% of cases respectively. One case showed evidence of aortic sclerosis. Dilated cardiomyopathy was present in 2.66% of cases. In 2.66% of cases systolic dysfunction and diastolic dysfunction each was evident. No patient showed evidence of vegetations. Anti SS-A and anti nucleosome (30.7% each) were the most common antibodies found in SLE patients with cardiovascular involvement. Increased serum LDL, hypertriglyceridemia and low serum HDL was found in 29%, 47% and 51% of patients respectively. Sub clinical myocardial injury was absent in all our patients as evidenced by negative serum Troponin-I. The CIMT was within normal limits and comparable between patients with and without cardiovascular involvement. The mean SLEDAI-2K was 7.3±4.9 and mean SDI was 0.8±1.2. SLEDAI-2K and SDI were significantly higher in patients with cardiovascular involvement versus patients without cardiovascular involvement (p=0.002 and p=0.01 respectively). SLEDAI-2K and SDI vs cardiac involvement Conclusion Cardiovascular involvement is associated with high SLEDAI-2K and SDI. Presence of anti-SSA and anti-nucleosome antibodies may predispose to cardiovascular involvement. Pericardial effusion was the most common echocardiographic abnormality. Low HDL was the most common dyslipidemia. However,atherosclerosis is not evident in patients with SLE with disease duration less than 5 years.

Purpose. We analyzed the prevalence, clinical correlation, and the functional significance of ALA in patients with systemic lupus erythematosus (SLE).Methods. ALA IgG was detected by indirect immunofluorescence in the serum of 130 SLE patients, 75 patients with various rheumatic diseases, and 45 healthy controls (HC).Results. The sensitivity and specificity of ALA IgG in SLE were 42.3% and 96.7%, respectively. ALA was observed in 55.6% (50/90) of patients with lymphopenia, which was significantly higher than in patients with normal lymphocytes (5/40, 12.5%;P<0.001). Patients with active SLE showed higher ALA positivity (60.9%) than those with inactive disease (24.2%;χ2= 17.925;P<0.001). ALA correlated significantly with hypocomplementemia, anti-dsDNA antibodies, and higher SLEDAI scores. The incidences of ALA in SLE patients who were seronegative for anti-dsDNA, anti-Sm, or both antibodies were 32.9% (26/79), 41.0% (43/105), and 32.4% (22/68), respectively. The ALA-positive group also had higher incidences of neuropsychiatric SLE (NPSLE) and lupus nephritis (LN). In multivariate analyses, ALA was independently associated with lymphopenia, higher SLEDAI scores, and increased risk for LN. ALA titers significantly decreased as clinical disease was ameliorated following treatment.Conclusions. ALA occurred more frequently in patients with active SLE and was independently associated with lymphopenia, disease activity, and LN.

Objective.Health related quality of life (HRQOL) is an important patient-reported outcome in systemic lupus erythematosus (SLE). We evaluated the psychometric properties of 2 widely used preference-based generic HRQOL measures, EuroQol-5D (EQ-5D) and Short Form-6D (SF-6D), among United States patients with SLE.Methods.Patients with SLE enrolled at an academic institution were assessed for self-reported generic HRQOL (EQ-5D, Medical Outcomes Study SF-36), disease activity, and disease damage SF-6D. Physical Component Score (PCS) and Mental Component Score (MCS) were calculated from SF-36. Criterion validity, convergent validity, and known-groups comparisons were evaluated for EQ-5D and SF-6D. Sensitivity to change (t tests, effect size) was evaluated in a subset of the cohort followed longitudinally.Results.One hundred sixty-seven patients with SLE were enrolled. Related domains on the EQ-5D and SF-36 correlated strongly, e.g., mobility and physical functioning (r = 0.60), whereas unrelated domains showed weak to moderate correlation. EQ-5D index, EQ-5D visual analog scale, and SF-6D score correlated strongly among each other as well as with most domains of SF-36. Both EQ-5D and SF-6D indices differentiated among patients of varied disease severity. EQ-5D and SF-6D were found to be sensitive to self-reported change in health but insensitive to change in disease activity longitudinally. Disease activity and damage showed weak correlation with HRQOL measures.Conclusion.The SF-6D and EQ-5D exhibited satisfactory psychometric properties for use among US patients with SLE. Measures of disease activity and damage were weakly correlated with HRQOL, suggesting that HRQOL is an important complementary source of information about patients with SLE.
