Factors affecting discrepancies in disease activity evaluation between patients and physicians in systemic lupus erythematosus-The importance of symptoms such as fatigue.

There are often discrepancies in the evaluation of disease activity between patients and physicians in systemic lupus erythematosus (SLE). In this study, we examined the factors that affect those evaluations. Physician visual analogue scale (Ph-VAS), patient VAS (Pt-VAS), Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2k), glucocorticoid (GC) usage and dose, age, Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index, and three patient-reported outcomes (SLE symptom checklist [SSC], short-form 36 questionnaire [SF-36], and LupusPRO) were obtained from a study performed in 2019 using 225 SLE outpatients of the Kyoto Lupus Cohort at Kyoto University Hospital. Correlations among Ph-VAS, Pt-VAS, or dif (Pt-VAS-Ph-VAS) (Pt-VAS minus Ph-VAS) and other factors were examined. We found a significant discrepancy between Pt-VAS (median 38.0mm) and Ph-VAS (median 18.7mm) scores (p < 0.001). SSC score showed a significant correlation with Pt-VAS and dif (Pt-VAS-Ph-VAS) (p < 0.001). Among SSC items, fatigue showed the most significant correlation with dif (Pt-VAS-Ph-VAS). We also showed that higher dif (Pt-VAS-Ph-VAS) was associated with lower quality of life (QOL) evaluated by SF-36 and LupusPRO. Pt-VAS scores tended to be higher than Ph-VAS scores, and the discrepancy was influenced mainly by fatigue. Higher dif (Pt-VAS-Ph-VAS) was associated with lower patient QOL.

Clinical Predictors of Mood Disorders and Prevalence of Neuropsychiatric Symptoms in Patients with Systemic Lupus Erythematosus.

Background/Objectives: We aimed to determine the prevalence and clinical correlations of mood disorders in a sample of systemic lupus erythematosus (SLE) patients. Hence, we hypothesized that the prevalence of mood disorders would be lower than reported in the literature and that patients would remain clinically stable and show less damage accrual despite low-dose corticosteroid prescription. Methods: In total, 92 SLE outpatients gave informed consent to participate in this cross-sectional study. Psychiatric and autoimmune clinical data were obtained, and a structured psychiatric interview was performed. The main clinical scales for the assessment of clinical symptomatology were included. To examine the potential relationships of presenting a mood disorder in SLE, clinical correlations and multivariate analyses were performed. Results: Mood disorders were the most prevalent disorder reported by SLE patients (16%), followed by adjustment disorders (5%). A significant proportion of patients presented psychosocial disturbances that did not meet the ICD-10 criteria for psychiatric diagnosis. According to the cut-off criterion for the Montgomery-Åsberg Depression Rating Scale (MADRS), up to 27% of the sample met the clinical criteria for depression. The multivariate analysis revealed a relationship between the presence of a mood disorder with total scores of the MADRS and the Young Mania Rating Scale (YMRS). Conclusions: The prevalence of mood disorders in patients with SLE was lower than previously reported. Although self-report clinical scales are useful for assessing clinical symptomatology, they should not be used in place of a comprehensive standardized interview conducted by a trained mental health specialist. Multidisciplinary teamwork is required for the early identification and therapeutic management of autoimmune patients with neuropsychiatric disorders.

Impact of disease activity patterns on health-related quality of life (HRQoL) in patients with systemic lupus erythematosus (SLE)

ObjectiveTo assess the impact of different disease activity patterns—long quiescent (LQ), chronically active (CA) and relapsing-remitting (RR)—on health-related quality of life (HRQoL) in a cohort of patients with systemic lupus...

Sustained agreement rates in the longitudinal assessment of lupus patients to a Broad Consent for personal data and specimen usage in the RHINEVIT biobank.

Biobanks are essential structures for scientific research. The RHINEVIT biobank is used to recruit biomaterials from rheumatology patients in outpatient care and to conduct clinical research studies (e.g., cohort studies) and basic research. RHINEVIT established Broad Consents (BC) to allow extensive and relevant usage of data and biospecimens without the need for specific project restrictions. For quality assurance, we compared the consent rate of individual items of the BC versions in patients with systemic lupus erythematosus (SLE) in the longitudinal study. BCs were used for biomaterial donation. Informed consent data from RHINEVIT were analyzed. Due to the content restructuring of the BC items due to changes from the templates of the working group of the Medical Ethics Commissions in the Federal Republic of Germany and GDPR requirements, content mapping of the items was performed for the analysis. From September 2015 to March 2022, 291 SLE outpatients donated biomaterials. In 119 patients, the BC was renewed at least once in a subsequent biomaterial donation. Three biomaterial donations were obtained from 21 patients and four from six patients using the respective BC. However, one consent was later revoked. Consent to the BC topics showed consistently high rates of agreement (range 97.5%-100%), with only some patients disagreeing with individual topics. This remained stable over time (median 526 days [Q1 400, Q3 844]). None of the patients disagreed with a certain topic in two consecutive visits. Modifications to the BC did not result in any relevant changes in the approval rates for SLE patients. RHINEVIT's BC is successfully used for the quality-assured handling of excellently annotated biomaterial. The long-term use of these highly valuable biospecimens for unrestricted research, also in an international context, remains assured.

Physical exercise is associated with less fatigue, less pain and better sleep in patients with systemic lupus erythematosus.

While fatigue is an extremely common complaint of patients with systemic lupus erythematosus (SLE), the information on factors influencing SLE fatigue in the long term is still limited. This study aims to investigate the actual level of physical activity in the daily life of SLE outpatients and its association with fatigue. In a cross-sectional survey on 93 SLE outpatients we combined clinical assessment with questionnaires to comprehensively assess SLE fatigue, its impact on function and health-related quality of life (hrQoL), and potential contributing factors, with particular emphasis on physical activity. Fatigue by visual analogue scores and FACIT fatigue scores correlated closely (r=-0.61, p<0.0001). We analysed fatigue in three patient groups, defined by both VAS and FACIT score, as those with severe fatigue, moderate fatigue, and less fatigue. Severe fatigue was associated with greatly diminished hrQoL. SLE patients regularly doing sports showed significantly lower fatigue values than those not doing sports; dog owners were less fatigued than other patients. Fatigue values were not significantly different between employed and unemployed patients. Severe fatigue was also associated with more pain and with shorter sleep duration and worse quality of sleep. This study finds a clear association of fatigue with physical activity, but also with pain and sleep disturbance, and reiterates the impact of fatigue on the SLE patients' quality of life.

Systemic Lupus Erythematosus Outpatients Medication Knowledge and Quality of Life

&lt;p&gt;According to the Indonesian Lupus Foundation (YLI) in the last decade, the number of people with SLE (Systemic Lupus Erythematosus) has continued to increase every year. This research was undertaken to assess the medication knowledge and quality of life among SLE outpatients who had been counselled by pharmacist. A cross-sectional, non-experimental, descriptive study design was used in this research. A total of 121 respondents from Semarang and Yogyakarta met the criteria. Seventy (57,85%) respondents had previous counseling, while 51 (42,15%) respondents never. Their knowledge score was 32,17 ± 3,52 and the quality of life was 59,23 ± 17,04. There was any correlation between the knowledge score and their quality of life. *P 0,014. Their average age was 31,53 ± 7,77 years. It was positively related with their Quality of life *P 0,031 but not to their knowledge score. The participants’ education level and disease duration were not considerably related with QoL and knowledge. Previous counseling by the pharmacists was positively related to their knowledge score, but not to their quality of life (*P 0,034 and 0,793). The conclusion that can be drawn is the SLE outpatients had low knowledge and their quality of life is not good enough. Pharmacists’ counseling can improve SLE outpatients’ knowledge scores significantly but not their QoL.&lt;strong&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;br /&gt;&lt;br /&gt;&lt;/p&gt;

Plasma and cerebrospinal fluid neurofilament light concentrations reflect neuronal damage in systemic lupus Erythematosus

Neuronal damage in systemic lupus erythematosus (SLE) is common, but the extent and mechanisms are unclear. Neurofilament light (NfL) concentrations rise in plasma and cerebrospinal fluid (CSF) during neuronal damage in various neurological disorders. In this cross-sectional study, plasma and CSF concentrations of NfL were explored as a marker of neuronal damage in SLE. Seventy-two consecutive SLE out-patients and 26 healthy controls, all female, aged < 55 years, underwent magnetic resonance imaging (MRI) and neurocognitive testing. NfL concentrations in plasma from all individuals and in CSF from 32 patients were measured with single-molecule array technology. Patients were assessed by a rheumatologist and neurologist to define neuropsychiatric involvement (NPSLE) according to three attribution models: SLICC A, SLICC B and ACR. Plasma and CSF NfL concentrations correlated strongly (r = 0.72, p < 0.001). Both NPSLE and non-NPSLE patients in all attribution models had higher plasma NfL concentrations compared with healthy controls (log-NfL, pg/ml, mean (SD); healthy controls (0.71 (0.17)); SLICC A model: NPSLE (0.87 (0.13), p = 0.003), non-NPSLE (0.83 (0.18), p = 0.005); SLICC B model: NPSLE (0.87 (0.14), p = 0.001), non-NPSLE (0.83 (0.18), p = 0.008); ACR model: NPSLE (0.86 (0.16), p < 0.001), non-NPSLE (0.81 (0.17), p = 0.044)). Plasma and CSF NfL concentrations did not differ between NPSLE and non-NPSLE patients. Higher plasma NfL concentrations correlated with larger CSF volumes on MRI (r = 0.34, p = 0.005), and was associated with poorer cognitive performance in the domains of simple attention, psychomotor speed and verbal memory. SLICC/ACR-Damage Index ≥1 was independently associated with higher plasma NfL concentrations (β = 0.074, p = 0.038). Higher plasma creatinine concentrations, anti-dsDNA-positivity, low complement C3 levels, or a history of renal involvement were associated with higher plasma NfL concentrations (β = 0.003, p = 0.009; β = 0.072, p = 0.031; β = 0.077, p = 0.027; β = 0.069, p = 0.047, respectively). Higher plasma NfL concentrations in NPSLE and non-NPSLE patients may indicate a higher degree of neuronal damage in SLE in general, corresponding to cognitive impairment and organ damage development. Furthermore, our results may indicate a higher degree of neuronal breakdown in patients with active SLE, also without overt clinical symptoms. NfL may serve as an indicator of neuronal damage in SLE in further studies.

Persistence of Depression and Anxiety despite Short-Term Disease Activity Improvement in Patients with Systemic Lupus Erythematosus: A Single-Centre, Prospective Study.

Mental disorders such as anxiety and depression are prevalent in systemic lupus erythematosus (SLE) patients, yet their association with the underlying disease activity remains uncertain and has been mostly evaluated at a cross-sectional level. To examine longitudinal trends in anxiety, depression, and lupus activity, a prospective observational study was performed on 40 adult SLE outpatients with active disease (SLE Disease Activity Index [SLEDAI]-2K ≥ 3 [excluding serology]) who received standard-of-care. Anxiety and depression were determined at baseline and 6 months by the Hospital Anxiety and Depression Scale. Treatment adherence was assessed with the Morisky Medication Adherence Scale-4. Increased anxiety (median [interquartile range] HADS-A: 11.0 [7.8]) and depression (HADS-D: 8.0 [4.8]) were found at inclusion, which remained stable and non-improving during follow-up (difference: 0.0 [4.8] and −0.5 [4.0], respectively) despite reduced SLEDAI-2K by 2.0 (4.0) (p < 0.001). Among possible baseline predictors, paid employment—but not disease activity—correlated with reduced HADS-A and HADS-D with corresponding standardized beta-coefficients of −0.35 (p = 0.017) and −0.27 (p = 0.093). Higher anxiety and depression correlated with lower treatment adherence (p = 0.041 and p = 0.088, respectively). These results indicate a high-mental disease burden in active SLE that persists despite disease control and emphasize the need to consider socioeconomic factors as part of comprehensive patient assessment.

Serum S100A8/A9 concentrations are associated with neuropsychiatric involvement in systemic lupus erythematosus: a cross-sectional study

BackgroundNeuropsychiatric (NP) involvement and fatigue are major problems in systemic lupus erythematosus (SLE). S100A8/A9 is a marker of inflammation and responds to therapy in SLE patients. S100A8/A9 has an immunopathogenic role in various neurological diseases. We investigated S100A8/A9 in relation to NP-involvement and fatigue in SLE.Methods72 consecutive SLE outpatients at a tertiary centre and 26 healthy controls were included in this cross-sectional study. NPSLE was determined by specialists in rheumatology and neurology and defined according to three attribution models: “ACR”, “SLICC A” and “SLICC B”. Cerebral MRI was assessed by a neuroradiologist and neurocognitive testing by a neuropsychologist. The individuals were assessed by scores of pain (VAS), fatigue (VAS and FSS), and depression (MADRS-S). Concentrations of S100A8/A9 in serum and cerebrospinal fluid were measured with ELISA. Statistical calculations were performed using non-parametric methods.ResultsSerum concentrations of S100A8/A9 were higher in SLE patients compared with controls (medians 1230 ng/ml; 790 ng/ml, p = 0.023). The concentrations were higher in NPSLE patients compared with non-NPSLE patients when applying the SLICC A and ACR models, but not significant when applying the SLICC B model (medians 1400 ng/ml; 920 ng/ml, p = 0.011; 1560 ng/ml; 1090 ng/ml, p = 0.050; 1460 ng/ml; 1090 ng/ml, p = 0.083, respectively). No differences of CSF S100A8/A9 concentrations were observed between NPSLE and non-NPSLE patients. SLE patients with depression or cognitive dysfunction as an ACR NPSLE manifestation had higher serum S100A8/A9 concentrations than non-NPSLE patients (median 1460 ng/ml, p = 0.007 and 1380 ng/ml, p = 0.013, respectively). Higher serum S100A8/A9 correlated with higher VAS fatigue (r = 0.31; p = 0.008) and VAS pain (r = 0.27, p = 0.021) in SLE patients. Serum S100A8/A9 was not independently associated with NPSLE when adjusting for scores of fatigue (FSS) and pain (VAS) (OR 1.86, 95% CI 0.93–3.73, p = 0.08).ConclusionsSerum S100A8/A9 concentrations may be associated with NPSLE and fatigue. S100A8/A9 may be of interest in evaluating NPSLE, although further investigations are needed.

Risk factors for the flare of systemic lupus erythematosus and its influence on prognosis: a single-center retrospective analysis

ObjectivesTo explore the risk factors for systemic lupus erythematosus (SLE) flare and their impact on prognosis.MethodsThe clinical characteristics, laboratory results, and treatment plans of 121 patients with SLE flare were retrospectively analyzed. Ninety-eight SLE outpatients with sustained remission during the same period were selected as controls. Logistic multivariate regression analysis was employed to screen for risk factors for SLE flare.ResultsInfection, thrombocytopenia, arthritis, anti-nucleosome antibodies positive, anti-β2-glycoprotein I (IgG) antibodies positive, and patient’s self-discontinuation of medicine maintenance therapy might be risk factors for SLE flare. Patients who discontinued medicine maintenance therapy by themselves had a significantly higher rate of severe SLE flare than patients with regular medicine maintenance therapy (P = 0.033). The incidence of anemia associated with SLE (P = 0.001), serositis (P = 0.005), and pulmonary hypertension (P = 0.003) in patients who discontinued medicine maintenance therapy were significantly higher than patients with regular medicine maintenance therapy. SLE patients with regular medicine maintenance therapy for less than 3 years had a higher risk of pulmonary hypertension than those with regular medicine maintenance therapy longer than 3 years (P = 0.034).ConclusionsThe accompanying thrombocytopenia, arthritis, anti-nucleosome antibodies positive and anti-β2-glycoprotein I (IgG) antibodies positive at the onset of SLE may affect the prognosis of SLE. Patient’s self-discontinuation of medicine maintenance therapy is the main cause of SLE flare, which may induce severe flare in SLE patients and lead to a significantly higher incidence of pulmonary hypertension.

Medication adherence is influenced by resilience in patients with systemic lupus erythematosus.

Evidence on the relationship between resilience and medication adherence in systemic lupus erythematosus (SLE) patients is lacking. We aimed to examine the impact of resilience on medication adherence in SLE patients. In a cross-sectional analysis SLE outpatients were assessed for resilience (Connor-Davison Resilience Scale, CD-RISC), depressive symptoms (CES-D) and medication adherence (Compliance Questionnaire for Rheumatology [CQR]). The disease activity index (mexSLEDAI) and damage (SLICC Damage Index) were administered. Factors independently associated with adherence were identified using multivariate logistic regression. Of the 157 patients, 152 (96.8%) were female with a median age of 45.9 (IQR: 39.0-55.5) years and disease duration of 14 (IQR: 10.0-19.0) years. Medication adherence (CQR ≥80%) and depressive symptoms were found in 74.5% and 43.9% of patients, respectively. Adherent patients had a lower CES-D score and a higher CD-RISC score. In the multivariate analysis adjusting for demographic and clinical confounders, resilience and older age protected against non-adherence (OR 0.96, [95% CI 0.94-0.99] and OR 0.96 [95% CI 0.93-0.98], respectively). In SLE patients, resilience and older age, which possibly associated with better medication adherence, may protect against non-adherence.

52528 Implementation of Web-Based Patient-Reported Outcome Measures (PROMs) in the Clinical Care of Systemic Lupus Erythematosus (SLE): A Multi-Center Prospective Cohort Study

ABSTRACT IMPACT: The integration of patient-reported outcome measures into clinical care is feasible and can facilitate patient-centered care for individuals with systemic lupus erythematosus. OBJECTIVES/GOALS: Patient-reported outcome measures (PROMs) are powerful tools which can facilitate patient-centered care by highlighting individuals’ experience of illness. The aim of this study was to assess the feasibility and impact of implementing web-based PROMs in the routine clinical care of outpatients with systemic lupus erythematosus (SLE). METHODS/STUDY POPULATION: Outpatients with SLE were enrolled in this longitudinal cohort study at two academic medical centers. Participants completed PROMIS computerized adaptive tests assessing multiple quality of life domains at enrollment and prior to two consecutive routinely scheduled rheumatology visits using the ArthritisPower research registry mobile or web-based application. Score reports were shared with patients and providers before the visits. Patients and rheumatologists completed post-visit surveys evaluating the utility of PROMs in the clinical encounters. Proportions with confidence intervals were calculated to evaluate survey completion rates and responses. RESULTS/ANTICIPATED RESULTS: A total of 105 SLE patients and 16 rheumatologists participated in the study. Subjects completed PROMs in 159 of 184 eligible encounters (86%, 95% CI 81 - 91), including 90% of visit 1’s (95% CI 82 - 95) and 82% of visit 2’s (95% CI 72 - 90. Patients and rheumatologists found that PROMs were useful (91% and 83% of encounters respectively) and improved communication (86% and 72%). Rheumatologists reported that PROMs impacted patient management in 51% of visits, primarily by guiding conversations (84%), but also by influencing medication changes (15%) and prompting referrals (10%). There was no statistically significant difference in visit length before (mean=19.5 min) and after (mean=20.4 min) implementation of PROMs (p=0.52). DISCUSSION/SIGNIFICANCE OF FINDINGS: The remote capture and integration of web-based PROMs into clinical care was feasible in a diverse cohort of SLE outpatients. PROMs were useful to SLE patients and rheumatologists and promoted patient-centered care by facilitating communication.

Responsiveness of the Patient-Reported Outcomes Measurement Information System Global Health Short Form in Outpatients With Systemic Lupus Erythematosus.

To evaluate the longitudinal responsiveness (sensitivity to change) of the Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health Short Form (PROMIS10) in outpatients with systemic lupus erythematosus (SLE). Outpatients with SLE who were receiving care at an academic medical center completed the PROMIS10 at 2 visits that were a minimum of 1 month apart. Responsiveness of the PROMIS10 global physical and mental health domains to Patient-Reported improvement or deterioration of health status was evaluated, as measured by standard validated instruments. Effect sizes of changes in PROMIS10 scores between visits were evaluated using Kruskal-Wallis testing. A total of 223 SLE patients enrolled and completed baseline surveys, with 186 (83.4%) completing a second set of questionnaires. The PROMIS10 demonstrated mild-to-moderate responsiveness to Patient-Reported improvement (effect size 0.29) and worsening (effect sizes -0.27 and -0.54) of health status for both global physical health and global mental health. Changes in the PROMIS10 correlated poorly with changes in physician-reported measures of disease activity. The PROMIS10 showed responsiveness over time to Patient-Reported changes in SLE health status, but not physician-assessed changes. These data suggest that the PROMIS10 can be used to efficiently measure and monitor important aspects of the SLE patient experience that are not captured by standard physician-derived metrics. Further studies are needed to evaluate the role of the PROMIS10 in optimizing longitudinal disease management in SLE and to determine its responsiveness in other chronic health conditions.

3047 Patient-Reported Outcomes Measurement Information System (PROMIS®) Global Health Short Form is Responsive to Patient Reported Changes in Systemic Lupus Erythematosus

OBJECTIVES/SPECIFIC AIMS: The accurate and efficient serial measurement of patient centered outcomes is a priority in the clinical care of systemic lupus erythematosus (SLE). Patient-Reported Outcomes Measurement Information Systems (PROMIS®) Global Health Short Form (PROMIS10) is a 10-item universal patient reported outcome measure of global physical and mental health with construct validity in SLE. The longitudinal responsiveness (sensitivity to change) of PROMIS10 in SLE patients is unknown. We aimed to evaluate the responsiveness of PROMIS10 in SLE outpatients using patient and physician-derived anchors. METHODS/STUDY POPULATION: Adults meeting SLE classification criteria were recruited from an SLE Center of Excellence. Subjects completed PROMIS10 at two visits a minimum of one month apart. SLE disease activity was measured with a patient global assessment of change, a physician global assessment and the physician-derived SELENA-SLEDAI. Responsiveness over time of PROMIS10 scores was evaluated using known-groups validity. Effect sizes of changes in PROMIS global physical health and global mental health scores from baseline to follow up were compared across groups of patients who differed in their patient global assessment of change, physician global assessment, and SELENA-SLEDAI using Kruskal-Wallis tests. RESULTS/ANTICIPATED RESULTS: A diverse cohort of 228 SLE patients completed baseline surveys (Table 1), with 190 (83%) completing a follow up survey. Using the patient-based anchor, PROMIS10 demonstrated mild to moderate responsiveness to improvement (effect size 0.29) and worsening (effect sizes −0.27 and −0.54) of health status for both global physical health and global mental health (Table 2). Using the physician global assessment and SELENA-SLEDAI as anchors, there were no statistically significant differences in effect sizes across groups. DISCUSSION/SIGNIFICANCE OF IMPACT: PROMIS10 showed responsiveness over time to patient-reported, but not physician-derived changes in lupus health status. These data suggest that PROMIS10 can be used to efficiently measure and monitor important aspects of the patient experience of lupus not captured by physician-derived metrics. Further studies are needed to evaluate the role of PROMIS in optimizing longitudinal disease management in SLE.

Prevalence of functional gastrointestinal disorders in adults with systemic lupus erythematosus.

Objective (a) to assess the prevalence of functional gastrointestinal disorders (FGIDs) in female Mexican systemic lupus erythematosus (SLE) patients using the Rome III criteria and (b) to examine the effect of disease duration on FGID prevalence. Methods Female SLE outpatients aged ≥18 years with no organic gastrointestinal disorder were included. Participants were invited to upper gastrointestinal endoscopy screening and a faecal immunochemical test. FGID symptoms were evaluated using the Rome III questionnaire. Results Eighty-six SLE patients with median age of 45 (interquartile range 34-54) years were included. At least one FGID was found in 76.7% (66/88) of patients with SLE. The most prevalent domains of FGID diagnosed were functional oesophageal, gastroduodenal disorders and bowel disorders, of which functional dyspepsia (72.7%), functional heartburn (68.1%) and bloating (63.8%) were the most frequent. Fifty-nine per cent of patients had overlapping FGIDs. The most prevalent overlap was the combination of functional dyspepsia and functional heartburn. Patients with longer disease duration had a higher prevalence of FGID than those with shorter disease duration. Conclusions There was a high prevalence of FGIDs in Mexican SLE women with low disease activity. Overlapping FGIDs were frequent. Longer disease duration may be associated with FGIDs in SLE patients.

Assessment of premature atherosclerosis in systemic lupus erythematosus patients with and without nephritis.

Risk of subclinical atherosclerosis is increased in patients with systemic lupus erythematosus (SLE). We correlated carotid intima media thickness (CIMT) and endothelial dysfunction through flow-mediated dilation (FMD) in SLE patients with the SLE Disease Activity Index (SLEDAI). This single-centre cross-sectional study recruited 100 consenting SLE outpatients (ACR 1997 criteria) out of which 50 had nephritis, with disease duration of ≥2 years for SLE and ≥6 months for lupus nephritis. We measured baseline laboratory levels, CIMT and FMD (after brachial BP cuff inflation up to 200 mmHg for five minutes), and calculated SLEDAI. Mean age was 29.88 ± 6.53 years; 95/100 were female. CIMT showed positive correlation (p = 0.037; rho = 0.209), and FMD showed inverse correlation with patient's age (p = 0.011; rho = -0.252). CIMT and FMD were more deranged in patients aged ≥25 years (p < 0.05). CIMT was not significantly different between SLE patients with and without nephritis (p > 0.05), whereas SLEDAI and FMD were more deranged in nephritis patients (p < 0.05). In patients without nephritis, FMD showed significant inverse correlation with disease duration (p = 0.043; rho = -0.288) and urine albumin (p = 0.045; rho = -0.285). In nephritis patients, the correlation between age of the patient was significantly positive with CIMT (p = 0.001; rho = 0.441) and significantly inverse with FMD (p = 0.028; rho = -0.312). SLE patients with nephritis are at a higher risk to develop arterial stiffening, leading to early end-organ damage. Early aggressive treatment may prevent endothelial dysfunction. FMD using vascular ultrasonography on the brachial artery represents a non-invasive, repeatable and useful method for the assessment of endothelial dysfunction.

Validation and evaluation of the German Brief Index of Lupus Damage (BILD) – a self-reported instrument to record damage in systemic lupus erythematosus

Damage is a very important predictor for outcome in systemic lupus erythematosus (SLE) and should be routinely documented. Patient-reported assessments for damage are rare and neither the Lupus Damage Index Questionnaire (LDIQ) nor the Brief Index of Lupus Damage (BILD) is validated in German language. Our aim was to validate the BILD in German language and evaluate its use as a patient-administered instrument. We translated and adapted the BILD questionnaire to use it as a self-administered questionnaire for German-speaking SLE patients. It was applied to SLE outpatients at an academic centre and compared to the SLICC/SDI and other lupus outcome parameters. The German BILD showed as strong a correlation with the SLICC/SDI as the original version of the BILD and a superior correlation compared to the LDIQ. It scored significantly higher with an increase of age, disease duration or disease activity, with a lower functional status or overall health and a higher probability of receiving an incapacity pension. The German version of the BILD shows a comparable validity to the original BILD with even higher correlation to physician-reported damage even when used as a self-administered questionnaire. Hence it represents a promising instrument to survey damage in clinical routine as well as in clinical and epidemiological studies.

Do subjective cognitive complaints correlate with cognitive impairment in systemic lupus erythematosus? A Danish outpatient study

This study examined the prevalence of cognitive impairment and its association with depressive symptoms and self-reported cognitive complaints in Danish outpatients with systemic lupus erythematosus (SLE). Fifty-seven consecutive female SLE-outpatients were examined with a comprehensive neuropsychological test-battery, a 20-item self-administered Perceived Deficits Questionnaire (PDQ) and a self-rated depression scale (Major Depression Inventory). Twenty-two patients (38.5%) were classified as cognitively impaired, mostly with deficits in executive functions and attention. Among cognitively impaired patients only 18.2% had significantly higher PDQ scores than the normal range. PDQ scores were highly correlated to depressive symptoms (r = 0.67, p < 0.001). Only two neuropsychological tests were significantly correlated with subjective cognitive complaints. When these variables and self-rated depression score were entered into a regression model both depression score and Symbol Digit Modalities Test performances were significantly associated with the PDQ score. In conclusion, cognitive impairments were common in this group of (mild) SLE outpatients, but the level of significant subjective cognitive complaints was low even among patients with cognitive impairment. Affective status may influence subjective experience of cognitive functions even more than cognitive functioning itself, and absence of subjective cognitive complaints did not exclude the presence of cognitive impairments.

Prevalence and factors associated with dyslipoproteinemias in Brazilian systemic lupus erythematosus patients

To determine the prevalence of dyslipoproteinemias and their related factors in a Brazilian systemic lupus erythematosus (SLE) population, fasting lipids were measured in 185 female SLE outpatients. Age, BMI, smoking, post-menopausal status, presence of diabetes and hypertension, SLE duration, number of ARA criteria, drug treatment and disease activity (by SLEDAI) were registered. Statistics included uni and multivariate logistic regression. Eighty-nine patients (48.1%) had hypercholesterolemia, 55 (29.7%) had hypertriglyceridemia and 109 (58.9%) had either. On multivariate analysis, 24-h proteinuria (OR = 2.08, 95% CI: 1.11-3.88), BMI (OR = 1.08, 95% CI: 1.01-1.16) and post-menopausal status (OR = 2.48, 95% CI: 1.25-4.92) were associated with hypercholesterolemia. Disease activity was related to low HDL-cholesterol (OR = 2.59, 95% CI: 1.20-5.58) and, in pre-menopausal patients, also to hypertriglyceridemia (OR = 1.16, 95% CI: 1.03-1.30). Antimalarial use was protective for hypertriglyceridemia (OR = 0.44, 95% CI: 0.22-0.90). In conclusion, the increased prevalence of dyslipoproteinemias is due to proteinuria, obesity and SLE activity. Antimalarials have beneficial effect on lipid profile that may be due to reduction in disease activity.

QT-interval parameters are increased in systemic lupus erythematosus patients

Systemic lupus erythematosus (SLE) patients have increased cardiovascular morbidity and mortality. QT-interval parameters are presumed markers of cardiovascular risk and have not been previously evaluated in SLE. Standard 12-lead ECGs were obtained from 140 female SLE outpatients and 37 age and body mass index-matched controls. QT interval was measured in each lead and heart rate-corrected maximum QT-interval duration (QTcmax) and QT-interval dispersion (QTd) were calculated. Risk factors for cardiovascular disease and lupus clinical features, disease treatment, disease activity and damage index were recorded. SLE patients have increased QT-interval parameters when compared to controls (QTcmax: 427.91 +/- 31.53 ms(1/2) versus 410.05 +/- 15.45 ms(1/2), P < 0.001; QTd: 52.38 +/- 22.21 ms versus 37.12 +/- 12.88 ms, P < 0.001). These differences persisted after excluding those patients with arterial hypertension, diabetes and with ECG abnormalities (QTcmax: 419.90 +/- 28.78 ms(1/2) versus 409.15 +/- 15.85 ms(1/2), P = 0.041; QTd: 54.74 +/- 26.00 ms versus 37.96 +/- 13.05 ms, P = 0.001). Multivariate linear regression for factors associated with QTcmax selected the presence of electrocardiographic left ventricular hypertrophy (ECG-LVH) (P = 0.003), nonspecific ST-T-wave abnormalities (P = 0.022) and left atrial enlargement (P = 0.044). Multivariate associates with QTd were age (P = 0.018), ECG-LVH (P = 0.022) and ST-T abnormalities (P = 0.031). In conclusion, SLE patients have increased QT interval parameters when compared to controls. This prolongation may lead to an increased cardiovascular risk. This finding might be due to subclinical atherosclerotic cardiovascular disease.
