Real-world data on vitamin D supplementation and its impacts in systemic lupus erythematosus: Cross-sectional analysis of a lupus registry of nationwide institutions (LUNA).

ABSTRACT:

Background

Although vitamin D concentration is reportedly associated with the pathogenesis and pathology of systemic lupus erythematosus (SLE), benefits of vitamin D supplementation in SLE patients have not been elucidated, to our knowledge. We investigated the clinical impacts of vitamin D supplementation in SLE.

Methods

A cross-sectional analysis was performed using data from a lupus registry of nationwide institutions. We evaluated vitamin D supplementation status associated with disease-related Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI) as a parameter of long-term disease activity control.

Results

Of the enrolled 870 patients (mean age: 45 years, mean disease duration: 153 months), 426 (49%) received vitamin D supplementation. Patients with vitamin D supplementation were younger (43.2 vs 47.5 years, P < 0.0001), received higher doses of prednisolone (7.6 vs 6.8 mg/day, P = 0.002), and showed higher estimated glomerular filtration rates (79.3 vs 75.3 mL/min/1.73m2, P = 0.02) than those without supplementation. Disease-related SDI (0.73 ± 1.12 vs 0.73 ± 1.10, P = 0.75), total SDI, and SLE Disease Activity Index (SLEDAI) did not significantly differ between patients receiving and not receiving vitamin D supplementation. Even after excluding 136 patients who were highly recommended vitamin D supplementation (with age ≥ 75 years, history of bone fracture or avascular necrosis, denosumab use, and end-stage renal failure), disease-related SDI, total SDI, and SLEDAI did not significantly differ between the two groups.

Conclusions

Even with a possible Vitamin D deficiency and a high risk of bone fractures in SLE patients, only half of our cohort received its supplementation. The effect of vitamin D supplementation for disease activity control was not observed.

Project description:IntroductionLupus nephritis (LN) is more prevalent in patients with SLE of Asian ethnicity than in Caucasian patients. Belimumab became available in Japan in 2017 to treat patients with SLE, including those with LN. In the BLISS-LN trial (NCT01639339), belimumab showed a favourable effect on renal outcomes when combined with standard therapy (ST) starting at the induction treatment phase for active LN, but real-world effectiveness of belimumab in LN has not been extensively studied. Here we describe the protocol for the MOONLIGHT (post-Marketed effectiveness of belimumab cOhOrt and JapaN Lupus NatIonwide ReGistry (LUNA) coHorT) study, which will use data from a Japan postmarketing surveillance study and the Lupus Registry of Nationwide Institutions (LUNA) to evaluate the real-world effectiveness of belimumab plus ST versus ST alone in patients with a history of active LN who are not in the induction phase.Methods and analysisThis multicentre, retrospective, observational study (GSK Study 214710) will enrol adults with SLE and a history of active LN, holding ≥3 years of complete follow-up data from the initiation of belimumab (no continuous treatment required). Data for patients with belimumab plus ST treatment (postmarketing registry data, belimumab cohort) will be compared with those for patients with ST only treatment (LUNA data, comparison cohort). Patients who discontinue/initiate belimumab after the start of the follow-up may be included in the comparison/belimumab cohort, respectively. The primary endpoint will be the occurrence of renal flares, for which belimumab's effectiveness will be estimated using a marginal structural model to consider time-dependent treatment and confounding factors. Secondary endpoints will include change in corticosteroid dose, renal disease activity, extrarenal disease activity, disease severity/activity biomarkers, LN class changes, end-stage kidney disease events and hospitalisations.Ethics and disseminationThis study will be conducted according to the Declaration of Helsinki and the local ethical guidelines. Findings will be submitted to peer-reviewed journals and presented at scientific meetings.

Project description:IntroductionBelimumab is a recombinant human monoclonal antibody that binds to soluble B-lymphocyte stimulator and inhibits its biological activity. Since receiving approvals for the treatment of systemic lupus erythematosus (SLE), several observational studies have investigated the effectiveness of belimumab in the real-world setting. This study reports a systematic review and meta-analysis of the literature to evaluate the real-world effectiveness of belimumab for the treatment of SLE.MethodsA literature search following PRISMA Guidelines and limited to studies in English was performed (2014-2020) to identify relevant studies reporting effectiveness outcomes of belimumab in patients with SLE. A modified version of the Newcastle-Ottawa Scale was used to assess study quality. Outcomes, including SLE Disease Activity Index (SLEDAI) score, prednisone-equivalent use, and SLE flare were pooled and analyzed using statistical aggregation methods.ResultsThe literature search identified 514 articles for initial review. Of these, 17 articles were suitable for data extraction and summary. Baseline characteristics of patients in real-world studies were generally similar to those of relevant clinical trials, including age, sex, disease duration, SLEDAI score, and prednisone-equivalent use. Real-world use of belimumab was associated with reductions in SLEDAI score (mean baseline score to month 6: 10.1-4.4; 57% reduction), prednisone-equivalent dosing (mean baseline dose to month 6: 12.1 mg/day to 6.9 mg/day; 43% reduction), and flare frequency (12 months prior to belimumab to 12 months after belimumab: 1.15-0.39 mean flares per patient per year; 66% reduction). Long-term data (up to 2 years post-treatment initiation) for SLEDAI score and prednisone-equivalent dose indicated that improvements in both outcomes continue over time among patients remaining on therapy.ConclusionsIn the real-world setting, observed outcomes with belimumab for the treatment of SLE are consistent with those reported from randomized clinical trials. Improvements persist long-term for SLEDAI activity and prednisone-equivalent use with belimumab.

Project description:BACKGROUND:The purpose of this study was to assess the prevalence, associated factors, and impact on mortality of primary respiratory disease in a large systemic lupus erythematosus (SLE) retrospective cohort. METHODS:All adult patients in the RELESSER-TRANS (Registry of Systemic Lupus Erythematosus Patients of the Spanish Society of Rheumatology [SER], cross-sectional phase) registry were retrospectively investigated for the presence of primary pleuropulmonary manifestations. RESULTS:In total 3215 patients were included. At least one pleuropulmonary manifestation was present in 31% of patients. The most common manifestation was pleural disease (21%), followed by lupus pneumonitis (3.6%), pulmonary thromboembolism (2.9%), primary pulmonary hypertension (2.4%), diffuse interstitial lung disease (2%), alveolar hemorrhage (0.8%), and shrinking lung syndrome (0.8%). In the multivariable analysis, the variables associated with the development of pleuropulmonary manifestation were older age at disease onset (odds ratio (OR) 1.03, 95% confidence interval (CI) 1.02-1.04), higher SLEDAI (Systemic Lupus Erythematosus Disease Activity Index) scores (OR 1.03, 95% CI 1.00-1.07), the presence of Raynaud's phenomenon (OR 1.41, 95% CI 1.09-1.84), secondary antiphospholipid syndrome (OR 2.20, 95% CI 1.63-2.97), and the previous or concomitant occurrence of severe lupus nephritis, (OR 1.48, 95% CI 1.12-1.95) neuropsychiatric manifestations (OR 1.49, 95% CI 1.11-2.02), non-ischemic cardiac disease (OR 2.91, 95% CI 1.90-4.15), vasculitis (OR 1.81, 95% CI 1.25-2.62), hematological manifestations (OR 1.31, 95% CI 1.00-1.71), and gastrointestinal manifestations, excluding hepatitis (OR 2.05, 95% CI 1.14-3.66). Anti-RNP positivity had a clear tendency to significance (OR 1.32, 95% CI 1.00-1.75; P = 0.054). The development of pleuropulmonary manifestations independently contributes to a diminished survival (hazard ratio of 3.13). However, not all complications will influence the prognosis in the same way. Whereas the occurrence of pleural disease or pulmonary thromboembolism has a minimal impact on the survival of these patients, the remaining manifestations have a major impact on mortality. CONCLUSION:Except for pleural disease, the remaining respiratory manifestations are very uncommon in SLE (<4%). Pleuropulmonary manifestations independently contributed to a decreased survival in these patients.
