Objective To define biopsychosocial mechanisms of pain that go above and beyond disease activity and organ damage in systemic lupus erythematosus (SLE). Methods We conducted a cross-sectional analysis of patient-reported data in a population-based registry of 766 people with SLE. Predictors of pain intensity and interference were examined using hierarchical linear regression. We built two main hierarchical regression models: pain intensity regressed on disease activity and organ damage; and pain interference regressed on disease activity and organ damage. For each model, we sought to establish the relationship between pain outcomes and the primary exposures using sequential steps comprising the inclusion of each construct in six stages: demographic, socioeconomic, physical, psychological, behavioral and social factors. We also conducted sensivity analyses eliminating all overt aspects of pain in the disease activity measure and reestimated the models. Results Disease activity and organ damage explained 32-33% of the variance in pain intensity and interference. Sociodemographic factors accounted for an additional 4-9% of variance in pain outcomes, while psychosocial/behavioral factors accounted for the final 4% of variance. In the sensitivity analyses, we found that disease activity and organ damage explained 25% of the variance in pain outcomes. Conclusion Disease activity only explained 33% of the variance of pain outcomes. However, there was an attenuation in these associations after accounting for psychosocial/behavioral factors, highlighting their roles in modifying the relationship between disease activity and pain. These findings suggest that multilevel interventions may be needed to tackle the negative impact of pain in SLE.

Objective Definitions of remission in systemic lupus erythematosus (SLE; DORIS (1A/1B/2A/2B)), disease activity assessments and patient-reported outcome measures (PROMs) are useful in shared decision making between patients with SLE and physicians. We used longitudinal registry data from well-characterized Swedish patients with recent-onset SLE to explore potential correlations between DORIS status or disease activity, and PROMs. Methods Patients from the Clinical Lupus Register in North-Eastern Gothia, Sweden, who fulfilled the 1982 American College of Rheumatology and/or the 2012 Systemic Lupus International Collaborating Clinics classification criteria without prior organ damage, were enrolled at diagnosis. Data on treatments, serology, remission status (DORIS), disease activity (SLE Disease Activity Index-2000 (SLEDAI-2K)) and PROMs (quality of life: EuroQoL-5 Dimensions (EQ-5D); pain intensity, fatigue and well-being: visual analog scale (VAS) 0–100 mm) were collected during rheumatology clinic visits at months 0 (diagnosis), 6, 12, 24, 36, 48 and 60. Correlations were assessed using Pearson correlation and/or beta regression coefficients. Results A total of 41 patients were enrolled (median age = 39 years, 80% female, 85% white). Achievement of DORIS 1A and 2A (neither of which includes serology) significantly correlated with all PROMs (EQ-5D: p ≤ 0.02; pain: p = 0.0001; fatigue: p = 0.0051; well-being: p < 0.0001). Disease activity measures were correlated with VAS pain intensity ( p < 0.03) and VAS well-being ( p < 0.04). Conclusions Our findings illustrate the importance of the interplay between remission, disease activity assessments and PROMs. PROMs may be a useful tool in clinical practice, being administered prior to patient visits to streamline clinical care.

The Impact

9618 Background: The COU-AA-301 phase 3 trial showed that AA + prednisone (P) improved overall survival in mCRPC patients (pts) post-docetaxel. Compared with P alone, AA + P also had significant benefits on patient-reported pain. Here we describe post hoc sensitivity analyses of pain data from that trial, using different methods to compensate for the potential impact of missing data. Methods: Pts with mCRPC progressing after docetaxel-based chemotherapy were randomized 2:1 to AA + P or placebo + P. Pain intensity and interference of pain with daily activities were assessed with the Brief Pain Inventory-Short Form (BPI-SF) questionnaire at baseline, Day 15 of Cycle 1, and Day 1 of each 28-day treatment cycle thereafter until treatment discontinuation. The effect of treatment on BPI-SF scores was analyzed using repeated measure mixed-effects (RMM) models, piecewise linear mixed-effects (PWLME) models, and joint mixed-effects and log time-to-dropout (JMEL) models. RMM and PWMLE models assumed missing data (due to death, study dropout, or administrative issues) to be missing at random, the JMEL model to be missing not at random. Model results were compared between treatment arms. Results: 797 pts were randomized to AA + P, and 398 to P only. RMM model estimates suggested statistically significant (p < 0.05) differences in change from baseline for pain intensity and pain interference scores in favor of AA + P at the majority of study visits through cycle 11. PWLME models yielded significantly smaller areas under the curve (AUCs) for AA + P vs P for pain intensity (p = 0.0031) and pain interference (p = 0.0006); smaller AUCs reflect better pain outcomes. Results using JMEL models were nearly identical to those with PWLME models, with AUCs for AA + P significantly smaller than for P alone for pain intensity (p = 0.0031) and pain interference (p = 0.0007). Conclusions: Using various modeling methods that assess the impact of missing data, AA + P showed superior patterns of pain outcomes over time compared with P only in mCRPC pts refractory to docetaxel. These results support the previously reported pain benefits of AA + P over P alone from the same trial. Clinical trial information: NCT00638690.

Abstract Objectives To identify predictors of low disease activity and clinical remission following belimumab treatment in SLE. Methods SLE patients who received belimumab 10 mg/kg (N = 563) in the BLISS-52 and BLISS-76 clinical trials were surveyed. The performance of baseline factors in predicting attainment of low disease activity (defined as Lupus Low Disease Activity State) or clinical remission [defined as clinical (c)SLEDAI-2K = 0] at week 52 from treatment initiation was evaluated using logistic regression. Organ damage was assessed using the SLICC/ACR Damage Index (SDI). Results We demonstrated a negative impact of established organ damage on attainment of Lupus Low Disease Activity State [SDI > 0; odds ratio (OR): 0.44; 95% CI 0.22, 0.90; P = 0.024] and the primary Lupus Low Disease Activity State condition, i.e. SLEDAI-2K ⩽ 4 with no renal activity, pleurisy, pericarditis or fever (SDI > 1; OR: 0.46; 95% CI 0.27, 0.77; P = 0.004); cognitive impairment/psychosis was found to mainly account for the latter association. Baseline SDI scores > 1 predicted failure to attain cSLEDAI-2K = 0 (OR: 0.53; 95% CI 0.30, 0.94; P = 0.030), with cutaneous damage mainly driving this association. Anti–dsDNA positivity increased (OR: 1.82; 95% CI 1.08, 3.06; P = 0.025) and cardiovascular damage reduced (OR: 0.13; 95% CI 0.02, 0.97; P = 0.047) the probability of attaining cSLEDAI-2K = 0 along with a daily prednisone equivalent intake restricted to ⩽7.5 mg. Conclusion Belimumab might be expected to be more efficacious in inducing low disease activity and clinical remission in SLE patients with limited or no organ damage accrued prior to treatment initiation. Patients with positive anti–dsDNA titres might be more likely to achieve clinical remission along with limited or no CS use.

The Relationship

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.

Background:Previous research in axial spondyloarthropathy(axSpA) has shown this population to have a high prevalence of depression. This co-morbidity has been previously shown to impact disease activity in patients with rheumatic disease.Objectives:The purpose of this study was to screen for early signs of depression using two validated tools, the Patient Health Questionaire-9 (PHQ-9) and the Hospital Anxiety and Depression Scale for depression (HADs-D) in patients with known axSpA.Methods:AxSpA patients attending the Rheumatology department in St James’ Hospital between February and October 2020 were invited to take a self-administered survey which included the PHQ-9 and the HADs-D. Scores from the HADs-D yielded a numerical result which was then categorised as normal, borderline or abnormal. PHQ-9 numerical results were categorised as normal, mild, moderate, moderate/severe or severe. Patients with a known diagnosis of depression were excluded. In addition to baseline demographics, patient reported outcomes from the clinic visit were also recorded.Data analysis was performed using IBM SPSS version 26. Continuous variables were recorded as means, categorical variables as frequencies with percentages. A one-way analysis of variance analysis (ANOVA) was used to determine significance of variation in outcomes between patient outcomes as determined by the HADs-D and PHQ-9. A p-value of <0.05 was deemed significant. Consent was obtained prior to participation. Approval was received from the St James’/Tallaght Hospital Joint Ethics Committee.Results:In total 71 axSpA patients took part in the survey. The population was 70.4%(50) males and 29.5%(21) female, with an average age 47.9 years and mean disease duration 19.7 years (mean outcomes: BASDAI 4.08, BASFI 3.62, BASMI 3.54, ASQoL 6.79). Overall, 7 (9.9%) participants recorded abnormal HADs-D scores, while 17 (23.9%) recorded moderate to severe PHQ-9 scores indicative of underlying depression. AxSpA females had higher mean HADs-D scores (7.5 vs 4.8, p=0.01) than males, with abnormal scores in 19%(4) of females and 6% (3) of males. No significant differences were found in PHQ-9 scores between genders.Analysis revealed significantly worse BASDAI (6.27 vs 3.42, p<0.01) and AQoL scores (12.57 vs 5.26, p<0.01) in axSpA patients with abnormal compared to normal HADs-D scores. No significant differences were noted in BASFI, BASMI or baseline demographics. A similar pattern was noted on analysis of PHQ-9 scores, with significantly worse BASDAI (7.9 vs 2.55, p<0.01), BASFI (8.05 vs 2.33, p<0.01) and ASQoL (19.5 vs 2.62, p<0.01) noted in those scoring as severe compared to normal. No significant differences were detected in BASMI scores or baseline demographics.Conclusion:A high percentage of axSpA patients recorded high HADs-D and PHQ-9 scores concerning for undiagnosed depression. These patients were noted to have significantly worse disease activity and quality of life as compared to patients with normal scores. Clinicians treating axSpA should consider screening for depression in this population.Disclosure of Interests:Sinead Maguire Speakers bureau: Speaker fee from Jassen, Grant/research support from: Recipient of the Gilead Inflammation Fellowship Grant, Finbar Barry O’Shea: None declared

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

Background:Systemic lupus erythematosus (SLE) is a chronic autoimmune disease of unknown etiology that can affect any organ of the body. SLE is associated with adverse effects on both health and non-health-related quality of life (HRQOL and non-HRQOL). Lupus PRO is a patient reported outcome measure that has been validated in many languages. It has 44 items that cover both HRQOL and non-HRQOL (1). Health literacy is defined as the degree to which individuals have the capacity to obtain, process and understand basic health information and services needed to make appropriate health decisions. Multiple studies indicate that people with limited health literacy have worse health status and higher rates of hospitalization (2).Objectives:We aimed to evaluate the relationship between the LLDAS (Lupus Low Disease Activity State) criteria and the Lupus PRO test, as well as the health literacy status of lupus patients.Methods:83 SLE patients (94% women) were included in the study. We performed Lupus PRO and the European Health Literacy Survey tests during the routine follow-up visits of lupus patients to our rheumatology outpatient clinic and admissions to rheumatology inpatient clinic. Available clinical data on medical records were obtained, physician global assessments (PGA) were recorded by the attending physician.Results:LLDAS criteria strongly and inversely correlated with the total score, as well as the mood subunit of the Lupus PRO. Similarly, it also significantly inversely correlated with the body appearence and goals subunits. Health literacy status of the patients did not correlate with their LLDAS scores, ie their disease activities.Conclusion:Our results suggest that lupus disease activity, assessed by LLDAS criteria, significantly correlates with measures of quality of life, spesicifically Lupus PRO test, but not with health literacy status. Further studies are needed to evaluate if health literacy is related with damage, hospitalization or mortality associated with lupus.References:[1]Jolly M, Pickard AS, Block JA, Kumar RB, Mikolaitis RA, Wilke CT, et al., editors.

Objective.To examine the role of disease activity on organ damage over 5 years in patients with active systemic lupus erythematosus (SLE) despite standard of care.Methods.This analysis of the University of Toronto Lupus Clinic cohort assessed organ damage [measured by Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI)] in patients with active SLE [SLE Disease Activity Index 2000 (SLEDAI-2K) ≥ 6], using Cox proportional time-independent hazard models. Subgroup analyses were conducted in patients with SLEDAI-2K 6 or 7, 8 or 9, and ≥ 10 at baseline, and in the overall study population by steroid dose at study entry (< 7.5 vs ≥ 7.5 mg/day).Results.Among the overall study population (n = 649), SDI progression was observed in 209 (32.2%) patients over the 5-year follow-up period. Mean SDI change in patients with a score > 0 was generally consistent across all SLEDAI-2K subgroups. Multivariable analyses identified age at study start (HR 1.03, P < 0.0001), steroid dose (HR 2.03, P < 0.0001), immunosuppressants (HR 1.44, P = 0.021), and SLEDAI-2K (subgroup analyses HR 1.64–2.03, P = 0.0017 to < 0.0001) as the greatest risk factors for SDI progression, while a study start date after the year 2000 had a protective effect on SDI progression compared with a start date prior to the year 2000 (HR 0.65, P = 0.0004).Conclusion.Patients within the higher SLEDAI-2K subgroups at study entry or receiving high doses of steroids were more likely to have organ damage progression.

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.
