- OBJECTIVE: To investigate whether abnormal BMI is associated with health-related quality of life (HRQoL) impairments, defined as patient-reported problems within the different dimensions of the three-level EQ-5D (EQ-5D-3L), before and after treatment for active systemic lupus erythematosus (SLE).PATIENTS AND METHODS: We conducted a post-hoc analysis of data from two phase III clinical trials of belimumab in SLE, i.e., BLISS-52 (n = 865) and BLISS-76 (n = 819). Underweight was defined as BMI <18.5 kg/m2, normal weight as BMI ≥18.5 but <25 kg/m2, pre-obesity as BMI ≥25 but <30 kg/m2, and obesity as BMI ≥30 kg/m2. We investigated associations between BMI groups and problems (level 2 or 3) within each one of the five EQ-5D dimensions before treatment initiation and at week 52, using logistic regression analysis adjusting for age, ethnicity, disease activity, and glucocorticoid dose, and for the post-treatment analysis also for belimumab treatment and baseline EQ-5D-3L responses.RESULTS: Of 1,684 patients included, 73 (4%) were classified as underweight, 850 (50%) as normal weight, 438 (26%) as pre-obese, and 323 (19%) as obese. At baseline, obesity was associated with mild to severe problems in all EQ-5D dimensions (p < 0.05 for all), yielding the strongest association with problems in mobility (adjusted odds ratio, aOR: 2.1; 95% confidence interval, CI: 1.6-2.8; p < 0.001). Pre-obesity was also associated with problems in mobility (aOR: 1.4; 95% CI: 1.1-1.8; p = 0.005). Post-intervention, obesity was associated with problems in mobility and pain/discomfort, and pre-obesity with problems in mobility and self-care (p < 0.05 for all).CONCLUSION: Our study adds to the evidence that high BMI negatively affects SLE patients' HRQoL, with obesity being associated with pain and impaired mobility despite therapy.

- OBJECTIVE: To identify determinants of medication non-adherence in a Swedish population of systemic lupus erythematosus (SLE).METHODS: Patients with SLE from Karolinska and Örebro University Hospitals participated in a survey-based cross-sectional study. Demographics, disease activity, organ damage, HRQoL (LupusQol, EQ-5D-5 L), medication non-adherence (<80% on CQR-19 or MASRI) and beliefs about medicines (BMQ) were registered. MASRI was used to report adherence to different drugs/drug classes, categorised into (i) antimalarial agents (AMA), (ii) glucocorticoids and (iii) other SLE medications. Multivariable logistic regression adjusted for age, sex, disease activity and organ damage.RESULTS: Among 205 respondents, the median age was 52.0 years (IQR: 34.0-70.0), 86.3% were women, 66.8% were non-adherent to their medications according to CQR-19, and 6.6% and 6.3% were non-adherent to AMA and glucocorticoids, respectively, according to MASRI. Positive beliefs about glucocorticoids (OR; 95% CI: 0.77; 0.59-0.99; p = .039) and medications overall (0.71; 0.52-0.97; p = .029) were protective against non-adherence to glucocorticoids. Anxiety/depression (3.09; 1.12-8.54; p = .029), medication concerns (1.12; 1.05-1.20; p < .001) and belief that medications are overused (1.30; 1.15-1.46; p < .001) or harmful (1.36; 1.19-1.56; p < .001) were associated with medication non-adherence (CQR-19); beliefs in the necessity of medications (0.73; 0.65-0.82; p < .001) and positive beliefs in medications were protective (0.72; 0.60-0.86; p < .001). No associations were found between other investigated factors and medication non-adherence.CONCLUSIONS: Beliefs about medications were a major determinant of medication non-adherence. Patient education may help alleviate the negative impact of misinformation/unawareness on adherence.

Tidskriftsartikel (refereegranskat)abstract
- Medication non-adherence is common among patients with systemic lupus erythematosus (SLE) and may lead to poor clinical outcomes. Our aim was to identify influenceable contributors to medication non-adherence and suggest interventions that could increase adherence. Patients with SLE from two Swedish tertiary referral centres (n = 205) participated in a survey assessing self-reported adherence to medications. Responses were used to select patients for qualitative interviews (n = 15). Verbatim interview transcripts were analysed by two researchers using content analysis methodology. The median age of the interviewees was 32 years, 87% were women, and their median SLE duration was nine years. Reasons for non-adherence were complex and multifaceted; we categorised them thematically into (i) patient-related (e.g., unintentional non-adherence due to forgetfulness or intentional non-adherence due to disbelief in medications); (ii) healthcare-related (e.g., untrustworthy relationship with the treating physician, authority fear, and poor information about the prescribed medications or the disease); (iii) medication-related (e.g., fear of side-effects); and (iv) disease-related reasons (e.g., lacking acceptance of a chronic illness or perceived disease quiescence). Interventions identified that healthcare could implement to improve patient adherence to medications included (i) increased communication between healthcare professionals and patients; (ii) patient education; (iii) accessible healthcare, preferably with the same personnel; (iv) well-coordinated transition from paediatric to adult care; (v) regularity in addressing adherence to medications; (vi) psychological support; and (vii) involvement of family members or people who are close to the patient.

- OBJECTIVES: To investigate the impact of remission and lupus low disease activity state (LLDAS) on health-related quality of life (HRQoL) in systemic lupus erythematosus.METHODS: SF-36, EQ-5D-3L and FACIT-Fatigue data from the BLISS-52 (NCT00424476) and BLISS-76 (NCT00410384) trials were used. Duration in remission/LLDAS required to reach a HRQoL benefit ≥ minimal clinically important differences (MCIDs) during and post-treatment was determined using quantile regression and generalised estimating equations.RESULTS: Patients (N = 1684) were assessed every 4th week (15 visits). Four cumulative (β = 0.60) or four consecutive (β = 0.66) visits in remission were required to achieve a benefit ≥MCID in SF-36 physical component summary (PCS) scores, and six cumulative (β = 0.44) or five consecutive (β = 0.49) for a benefit ≥MCID in mental component summary (MCS) scores. Eight cumulative (β = 0.30 for both) or eight consecutive (β = 0.32 for both) visits in LLDAS were required for a benefit in PCS/MCS ≥MCID, respectively.For EQ-5D-3L index scores ≥MCID, six cumulative (β = 0.007) or five consecutive (β = 0.008) visits in remission were required, and eight cumulative (β = 0.005) or six consecutive (β = 0.006) visits in LLDAS. For FACIT-Fatigue scores ≥MCID, 12 cumulative (β = 0.34) or 10 consecutive (β = 0.39) visits in remission were required, and 17 cumulative (β = 0.24) or 16 consecutive (β = 0.25) visits in LLDAS.CONCLUSION: Remission and LLDAS contribute to a HRQoL benefit in a time-dependent manner. Shorter time in remission than in LLDAS was required for a clinically important benefit in HRQoL, and longer time in remission for a benefit in mental compared with physical HRQoL aspects. When remission/LLDAS was sustained, the same benefit was achieved in a shorter time.

- Background/Purpose: Health- related quality of life (HRQoL) is considered one of the most important outcomes in clinical trials of systemic lupus erythematosus (SLE), along with reduction in disease activity and safety. We studied the duration and consecutiveness of remission or low disease activity throughout a 52- week long period on standard therapy plus belimumab or placebo in relation to HRQoL outcome.Methods: We analysed pooled 52- week data from the BLISS- 52 (N=865) and BLISS- 76 (N=819) phase III trials. We determined remission using the prevailing Definitions of Remission in SLE (DORIS) definition (1) and low disease activity using the Lupus Low Disease Activity State (LLDAS) (2). Remission required clinical (c)SLEDAI- 2K=0, PhGA (0– 3) <0.5, and prednisone ≤5 mg/day. LLDAS required SLEDAI- 2K ≤4, PhGA (0– 3) ≤1, and prednisone ≤7.5 mg/day. HRQoL was measured with the SF- 36 physical and mental component summary (PCS and MCS), and EQ- 5D- 3L. Minimal clinically important difference (MCID) at week 52 for PCS and MCS was set to 2.5, and for EQ- 5D- 3L utility index to 0.040. Associations were assessed using quantile regression analysis. Adjustments for demographics, disease duration, organ damage and baseline status were incorporated.Results: The minimum cumulative attainment of remission to achieve a benefit in PCS ≥MCID at week 52 was four visits (corresponding to 16 weeks) (β=0.63), while 7 visits (28 weeks) were required for MCS differences ≥MCID (β=0.37). Correspondingly, 9 visits in LLDAS (36 weeks) were required for achieving differences ≥MCID in both PCS (b=0.28) and MCS (β=0.29). Table 1 shows 95% confidence intervals and p values. When analysing the impact of sustained remission and LLDAS, four consecutive visits in remission (16 weeks) were required for PCS ≥MCID (b=0.70), whereas six visits (24 weeks) were required for MCS ≥MCID (b=0.46). Sustained LLDAS for nine consecutive visits (36 weeks) was needed for PCS and MCS ≥MCID (b=0.31 and 0.31, respectively). For EQ- 5D ≥MCID to be reached, a cumulative total of seven visits (28 weeks) in remission (b=0.006), or eight visits (32 weeks) in LLDAS (b=0.005) was required, whereas if sustained, remission for six visits (24 weeks; b=0.008) or LLDAS for seven visits (28 weeks; b=0.006) were sufficient.Conclusion: Attainment of remission or LLDAS in the BLISS- 52 and BLISS- 76 trials of belimumab was associated with improved HRQoL. Less time was required in remission than in LLDAS to achieve clinically important differences in multiple HRQoL aspects. Clinically important differences in HRQoL required shorter total time if the remission or LLDAS was sustained. Clinically important differences in mental aspects of HRQoL required longer time in remission than physical aspects. The impact of cumulative and sustained remission or LLDAS on HRQoL adds evidence on the clinical importance of these treat- to- target endpoints.References:1) van Vollenhoven R. et al.

Forskningsöversikt (refereegranskat)abstract
- Systemic lupus erythematosus (SLE) is a chronic, autoimmune disease, characterised by a relapsing-remitting pattern of inflammatory activity, with each relapse contributing to irreversible end-organ damage with detrimental effects on patients' course, adding up to morbidity burden and shortening life-length. Along with several other demographic, socioeconomic, and life-style factors, high inflammatory activity and accrued organ damage have been coupled with adverse health-related quality of life (HRQoL) within physical, mental, and psychosocial aspects. The management of SLE has improved substantially during the last decades, owing to a technological explosion that has advanced drug development towards more targeted options. Being the first drug to be approved for SLE in more than half a century and the first in history biological agent for SLE, the introduction in 2011 of the monoclonal antibody belimumab that specifically binds to the soluble counterpart of B cell activating factor (BAFF) was a breakthrough in SLE drug development. The efficacy and favourable safety profile of belimumab has been demonstrated across several clinical trials and observational studies. Herein, we reviewed the literature and provide a summary on the effects of belimumab on SLE patients' HRQoL based on 23 studies. Belimumab has been shown to induce clinically important improvements in physical aspects of HRQoL and in fatigue, the latter being a common and major complaint within the SLE population. People with SLE overall benefit more from belimumab within physical compared with mental aspects of HRQoL. However, despite improvements of clinical and immunological features upon therapy with belimumab, HRQoL perception remains unsatisfactory for a substantial percentage of the patients. Finally, our review made apparent an urgent need for optimisation of the use of patient-reported outcome measures, both in research and clinical practice.

- OBJECTIVES: To investigate the ability of different EQ-5D-3L index scores to discriminate between verum drug and placebo (discriminant validity) as well as between responders and non-responders (known-groups validity) in the SLE patient population of two phase III clinical trials of belimumab.METHODS: Data from the BLISS-52 (NCT00424476) and BLISS-76 (NCT00410384) trials (N = 1684), which both showed superiority of belimumab to placebo, were utilised. Responders were defined as SLE Responder Index 4 (SRI-4) achievers at week 52. The Pearson's χ2 and Mann-Whitney U tests were used for comparisons, and logistic regression analysis was used for adjustments for confounders and assessment of independence.RESULTS: While full health state (FHS; EQ-5D index score 1) showed the best ability to discriminate between belimumab and placebo (adjusted OR: 1.47; 95% CI: 1.11-1.96; P = 0.008) and between SRI-4 responders and non-responders (adjusted OR: 3.47; 95% CI: 1.29-10.98; P = 0.020), the discriminative ability of EQ-5D index scores 0.800 or more reached statistical significance for both discriminant validity (adjusted OR: 1.29; 95% CI: 1.02-1.63; P = 0.036) and known-groups validity (adjusted OR: 3.08; 95% CI: 1.16-9.69; P = 0.034).CONCLUSION: Overall, higher EQ-5D index scores were associated with increasing ability to discriminate between belimumab and placebo, and between responders and non-responders. EQ-5D index scores less stringent than FHS may be clinically relevant HRQoL goals of treatment in patients with SLE, introducing the concept of EQ-5D adequate health state when FHS is not achievable.

- OBJECTIVES: We aimed at investigating the whole-blood transcriptome, expression quantitative trait loci (eQTLs), and levels of selected serological markers in patients with SLE versus healthy controls (HC) to gain insight into pathogenesis and identify drug targets.METHODS: We analyzed differentially expressed genes (DEGs) and dysregulated gene modules in a cohort of 350 SLE patients and 497 HC from the European PRECISESADS project (NTC02890121), split into a discovery (60%) and a replication (40%) set. Replicated DEGs qualified for eQTL, pathway enrichment, regulatory network, and druggability analysis. For validation purposes, a separate gene module analysis was performed in an independent cohort (GSE88887).RESULTS: Analysis of 521 replicated DEGs identified multiple enriched interferon signaling pathways through Reactome. Gene module analysis yielded 18 replicated gene modules in SLE patients, including 11 gene modules that were validated in GSE88887. Three distinct gene module clusters were defined i.e., "interferon/plasma cells", "inflammation", and "lymphocyte signaling". Predominant downregulation of the lymphocyte signaling cluster denoted renal activity. By contrast, upregulation of interferon-related genes indicated hematological activity and vasculitis. Druggability analysis revealed several potential drugs interfering with dysregulated genes within the "interferon" and "PLK1 signaling events" modules. STAT1 was identified as the chief regulator in the most enriched signaling molecule network. Drugs annotated to 15 DEGs associated with cis-eQTLs included bortezomib for its ability to modulate CTSL activity. Belimumab was annotated to TNFSF13B (BAFF) and daratumumab was annotated to CD38 among the remaining replicated DEGs.CONCLUSIONS: Modulation of interferon, STAT1, PLK1, B and plasma cell signatures showed promise as viable approaches to treat SLE, pointing to their importance in SLE pathogenesis.
