- 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.

- OBJECTIVES: To update the EULAR recommendations for the management of systemic lupus erythematosus (SLE) based on emerging new evidence.METHODS: An international Task Force formed the questions for the systematic literature reviews (January 2018-December 2022), followed by formulation and finalisation of the statements after a series of meetings. A predefined voting process was applied to each overarching principle and recommendation. Levels of evidence and strengths of recommendation were assigned, and participants finally provided their level of agreement with each item.RESULTS: The Task Force agreed on 5 overarching principles and 13 recommendations, concerning the use of hydroxychloroquine (HCQ), glucocorticoids (GC), immunosuppressive drugs (ISDs) (including methotrexate, mycophenolate, azathioprine, cyclophosphamide (CYC)), calcineurin inhibitors (CNIs, cyclosporine, tacrolimus, voclosporin) and biologics (belimumab, anifrolumab, rituximab). Advice is also provided on treatment strategies and targets of therapy, assessment of response, combination and sequential therapies, and tapering of therapy. HCQ is recommended for all patients with lupus at a target dose 5 mg/kg real body weight/day, considering the individual's risk for flares and retinal toxicity. GC are used as 'bridging therapy' during periods of disease activity; for maintenance treatment, they should be minimised to equal or less than 5 mg/day (prednisone equivalent) and, when possible, withdrawn. Prompt initiation of ISDs (methotrexate, azathioprine, mycophenolate) and/or biological agents (anifrolumab, belimumab) should be considered to control the disease and facilitate GC tapering/discontinuation. CYC and rituximab should be considered in organ-threatening and refractory disease, respectively. For active lupus nephritis, GC, mycophenolate or low-dose intravenous CYC are recommended as anchor drugs, and add-on therapy with belimumab or CNIs (voclosporin or tacrolimus) should be considered. Updated specific recommendations are also provided for cutaneous, neuropsychiatric and haematological disease, SLE-associated antiphospholipid syndrome, kidney protection, as well as preventative measures for infections, osteoporosis, cardiovascular disease.CONCLUSION: The updated recommendations provide consensus guidance on the management of SLE, combining evidence and expert opinion.

- OBJECTIVE: Rituximab is a monoclonal antibody directed against the CD20 marker of B cells. Because of its ability to deplete B lymphocytes, it has been suggested that the drug could be of benefit in B cell-dependent diseases, including systemic lupus erythematosus (SLE). The purpose of this study was to investigate the histopathologic and clinical effects of combination treatment with rituximab and cyclophosphamide (CYC) in patients with CYC-resistant proliferative lupus nephritis.METHODS: Seven female patients with proliferative lupus nephritis were treated with rituximab in combination with CYC. Renal biopsies were performed before treatment and during followup. SLE activity was evaluated by the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and the British Isles Lupus Assessment Group index. In 6 of the 7 patients, immunostaining of lymphocyte subpopulations in the renal tissue was performed before treatment and during followup.RESULTS: At 6 months of followup, significant clinical improvement was noted, with a reduction in SLEDAI scores (from a mean of 15 to 3), anti-double-stranded DNA antibody levels (from a mean of 174 IU/ml to 56 IU/ml), and anti-C1q antibody levels (from a mean of 35 units/ml to 22 units/ml). On repeat renal biopsy, improvement in the histopathologic class of nephritis occurred in a majority of patients, and a decrease in the renal activity index was noted (from 6 to 3). A reduction in the number of CD3, CD4, and CD20 cells in the renal interstitium was noted in 50% of the patients on repeat biopsy.CONCLUSION: At 6 months of followup, all patients had responded both clinically and histopathologically to combination therapy. For patients with proliferative lupus nephritis who fail to respond to conventional immunosuppressive therapy including CYC, combined treatment with rituximab and CYC may constitute a new treatment option.

- OBJECTIVE: To investigate the long-term clinical, histological and serological affects of B-cell-depleting therapy (BCDT) in patients with LN refractory to conventional treatment.METHODS: Twenty-five patients, followed for a mean time of 36 months (9-95 months), were included. Renal disease activity was evaluated with the BILAG index and renal response was determined according to the LN European consensus statement. Renal biopsies were performed for histological evaluation at baseline and follow-up.RESULTS: Partial response (PR) or complete renal response (CR) was observed in 22 of 25 after a median of 12 months. Sixteen patients achieved CR after a median of 24 months. Six patients experienced a renal relapse. Proteinuria decreased significantly (P = 0.0002) from baseline to 36 months. A noteworthy histological improvement was seen in nearly all patients with a significant reduction in activity index (P = 0.01). Longer depletion time and low baseline values of IgM were indicative of achieving clinical remission during the first year after treatment (P = 0.03 and P = 0.04, respectively).CONCLUSION: In therapy-resistant LN, BCDT induced clinical and histological improvements in the majority of patients. Transition from PR to CR was mainly seen during the second year of follow-up. Patients with longer depletion time and low baseline levels of IgM were more likely to gain a faster remission, suggesting that the clinical benefit may be linked to suppression of autoreactive plasmablasts. Although formal evidence of BCDT in LN is lacking, our data may provide guidance to clinicians considering therapeutic options in patients with refractory LN.

- OBJECTIVE: To evaluate efficacy, serological responses, and predictors of response in patients with severe and refractory systemic lupus erythematosus (SLE) treated with rituximab plus cyclophosphamide.METHODS: 16 patients entered a treatment protocol using rituximab plus cyclophosphamide. Disease activity was assessed by the SLE disease activity index (SLEDAI) and by the British Isles Lupus Assessment Group (BILAG) index.RESULTS: At six months follow up, mean SLEDAI values decreased significantly from (mean (SD)) 12.1 (2.2) to 4.7 (1.1). Clinical improvement (50% reduction in SLEDAI) occurred in all but three patients. All but one patient responded according to BILAG. Remission defined as SLEDAI <3 was achieved in nine of 16 patients. Isotype analysis of anti-dsDNA antibodies revealed preferential decreases of IgG and IgA, but not IgM. Higher absolute numbers of CD19+ cells at baseline were correlated with shorter depletion time (r = -0.6).CONCLUSIONS: The majority of patients improved following rituximab plus cyclophosphamide. The differential downregulation of anti-DNA of the IgG and IgA but not the IgM isotypes supports the hypothesis that cells producing pathogenic autoantibodies are preferentially targeted by the treatment. The fact that greater absolute numbers of CD19+ cells at baseline predict a less impressive clinical and serological response suggests that more flexible dosing could be advantageous.

- BACKGROUND: Disease remission or low disease activity are key treatment targets for patients with systemic lupus erythematosus (SLE). Pivotal trials of belimumab were conducted before the introduction of these targets. In this study, we aimed to pool data across trials to assess attainment of remission and low disease activity in a large, racially and culturally diverse patient population with SLE.METHODS: In this integrated post-hoc analysis, we pooled data from five phase 3 trials of belimumab (BLISS-76 [NCT00410384], BLISS-52 [NCT00424476], BLISS-NEA [NCT01345253], BLISS-SC [NCT01484496], and EMBRACE [NCT01632241]), in patients with active, autoantibody-positive SLE. Patients were randomly assigned to receive belimumab (10 mg/kg per month intravenously or 200 mg per week subcutaneously) or placebo, plus standard therapy. The proportion of patients with Definitions of Remission in SLE (DORIS) remission and lupus low disease activity state (LLDAS) were analysed every 4 weeks from week 4 to week 52 for belimumab versus placebo, using modified Poisson regression adjusted for trial variance, in all patients and in subgroups per baseline SLE Disease Activity Index-2000 score (<10 or ≥10); anti-double stranded DNA positivity (yes or no); low complement 3 (C3) or C4 levels (yes or no); anti-dsDNA positivity or low C3 or C4 levels (yes and no); prednisone-equivalent dose (≤7·5 mg per day or >7·5 mg per day); antimalarial use (yes or no); and by race (Black African ancestry or African American, Asian, Indigenous American, or White). FINDINGS: Data for 3086 patients (1869 in the belimumab group and 1217 in the placebo group) were analysed. 2913 (94%) of 3086 patients were women and 173 (6%) were men, and the median age was 36 years (IQR 28-45). The proportion of patients with DORIS remission was significantly higher in the belimumab group than the placebo group at weeks 28, 48, and 52 (week 52: 148 [8%] of 1869 participants vs 68 [6%] of 1217 participants; risk ratio 1·51 [95% CI 1·15-1·99]; p=0·0055). The proportion of patients who attained LLDAS was higher in the belimumab group than the placebo group at weeks 8, 24, 32-52 (week 52: 322 [17%] of 1869 participants vs 125 [10%] of 1217 participants; 1·74 [1·44-2·12]; p<0·0001). A higher proportion of patients had DORIS remission at week 52 in the belimumab group than the placebo group among all baseline subgroups denoting high disease activity, with the exception of those on a prednisone-equivalent dose higher than 7·5 mg per day in whom there was no difference for DORIS remission with belimumab versus placebo. The proportion of patients with LLDAS was significantly higher among patients in the belimuab group than those who received placebo from week 44 in all baseline subgroups denoting high disease activity or earlier in some subgroups, and the differences were maintained at week 52.INTERPRETATION: In adults with active SLE, belimumab plus standard therapy yielded greater benefit than placebo plus standard therapy in attaining DORIS remission (for which low rates were attained in both groups) and LLDAS, with differences observed as early as week 28 for DORIS remission and week 8 for LLDAS.FUNDING: Swedish Rheumatism Association, King Gustaf V's 80-year Foundation, Swedish Society of Medicine, Nyckelfonden, Professor Nanna Svartz Foundation, Ulla and Roland Gustafsson Foundation, Region Stockholm, and the Karolinska Institutet.

- BACKGROUND: The monoclonal anti-B cell antibody rituximab (Rituxin, Mabthera) may be of benefit in antibody-driven diseases, including systemic lupus erythematosus (SLE) nephritis.PATIENTS AND TREATMENT: Two female patients with biopsy-confirmed severe and active SLE nephritis despite treatment with cyclophosphamide (CyX) were given four rituximab infusions plus two additional CyX infusions.RESULTS: Both patients tolerated the treatment well and SLE activity improved. On repeat kidney biopsy after the combined treatment, Patient 1 showed a profound reduction of nephritis activity, and she was maintained on low-dose prednisolone only. A repeat biopsy after 1 year confirmed the sustained reduction of lupus nephritis activity. In Patient 2, rebiopsy after combined treatment also showed a significant reduction in disease activity.CONCLUSION: These cases provide histopathological documentation of a significant treatment benefit from rituximab plus CyX in two patients refractory to CyX alone. This combination is being explored further as salvage therapy for such CyX-resistant patients.
