LUPUS-BEST-treat-to-target in systemic lupus erythematosus: study protocol for a three-armed cluster-randomised trial

Opportunities and challenges of lupus care in Latin America, the Middle East, and Asia-Pacific: A call to action

Lupus remains a disease with a low prioritisation in the national agendas of many countries in Latin America, the Middle East, and Asia-Pacific, where there is a dearth of rheumatologists and limited access to new or even standard lupus treatments. There is thus an important need for education, advocacy, and outreach to prioritise lupus in these regions to ensure that patients receive the care they need. This article reviews some of the specific challenges facing the care and management of people with lupus in these regions and suggests strategies for improving patient outcomes. Specifically, we review and discuss (with a focus on the aforementioned regions) the epidemiology of lupus; economic costs, disease burden, and effects on quality of life; barriers to care related to disease assessment; barriers to effective treatment, including limitations of standard treatments, high glucocorticoid use, inadequate access to new treatments, and low adherence to medications; and strategies to improve lupus management and patient outcomes. We hope that this represents a call to action to come together and act now for the lupus community, policymakers, health authorities, and healthcare professionals to improve lupus management and patient outcomes in Latin America, the Middle East, and Asia-Pacific.

Evolving Concepts in Treat-to-Target Strategies for Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that is characterised by a wide range of symptoms and a risk for irreversible organ damage, leading to increased morbidity and mortality. To improve long-term outcomes, innovative therapeutic goals have been explored, including attainment and maintenance of remission or low disease activity, with minimal use of glucocorticoids. Other goals encompass early diagnosis, potent yet less toxic therapies, appropriate glucocorticoid tapering, and better quality of life for the patients. Implementing a treat-to-target (T2T) approach involves treatment adjustments to achieve predefined objectives. Evidence from other chronic diseases, like hypertension and diabetes, supports the success of target-based approaches. In rheumatic diseases, the multitude of clinical features adds complexity to T2T strategies, but in rheumatoid arthritis, T2T has yielded improved outcomes. The application of T2T in SLE requires realistic therapeutic goals and practical tools for their measurement. International task forces have developed T2T recommendations for SLE, focusing on limiting disease activity, preventing organ damage, and minimising glucocorticoid use, while considering patients' quality of life. Advancements in defining clinically meaningful remission and low disease activity states, coupled with promising novel therapies, have spurred progress in the management of SLE.

Management of systemic lupus erythematosus: a systematic literature review informing the 2023 update of the EULAR recommendations

OBJECTIVES

To analyse the new evidence (2018-2022) for the management of systemic lupus erythematosus (SLE) to inform the 2023 update of the European League Against Rheumatism (EULAR) recommendations.

METHODS

Systematic literature reviews were performed in the Medline and the Cochrane Library databases capturing publications from 1 January 2018 through 31 December 2022, according to the EULAR standardised operating procedures. The research questions focused on five different domains, namely the benefit/harm of SLE treatments, the benefits from the attainment of remission/low disease activity, the risk/benefit from treatment tapering/withdrawal, the management of SLE with antiphospholipid syndrome and the safety of immunisations against varicella zoster virus and SARS-CoV2 infection. A Population, Intervention, Comparison and Outcome framework was used to develop search strings for each research topic.

RESULTS

We identified 439 relevant articles, the majority being observational studies of low or moderate quality. High-quality randomised controlled trials (RCTs) documented the efficacy of the type 1 interferon receptor inhibitor, anifrolumab, in non-renal SLE, and belimumab and voclosporin, a novel calcineurin inhibitor, in lupus nephritis (LN), when compared with standard of care. For the treatment of specific organ manifestations outside LN, a lack of high-quality data was documented. Multiple observational studies confirmed the beneficial effects of attaining clinical remission or low disease activity, reducing the risk for multiple adverse outcomes. Two randomised trials with some concerns regarding risk of bias found higher rates of relapse in patients who discontinued glucocorticoids (GC) or immunosuppressants in SLE and LN, respectively, yet observational cohort studies suggest that treatment withdrawal might be feasible in a subset of patients.

CONCLUSION

Anifrolumab and belimumab achieve better disease control than standard of care in extrarenal SLE, while combination therapies with belimumab and voclosporin attained higher response rates in high-quality RCTs in LN. Remission and low disease activity are associated with favourable long-term outcomes. In patients achieving these targets, GC and immunosuppressive therapy may gradually be tapered. Cite Now.

First validation of the childhood lupus low disease activity state (cLLDAS) definition in a real-life longitudinal cSLE cohort

OBJECTIVES

To validate the childhood lupus low disease activity state (cLLDAS) definition in cSLE by describing differences in time to reach first adult LLDAS (aLLDAS) versus cLLDAS. Secondly, to analyse positive and negative predictors for maintaining cLLDAS for at least 50% of follow-up time (cLLDAS-50) and for the occurrence of damage.

METHODS

Prospective longitudinal data from a cSLE cohort were analysed. Used definitions were: aLLDAS according to Franklyn, cLLDAS by cSLE treat-to-target (T2T) Task Force, disease activity score by SLEDAI -2 K and damage by SLICC damage index.

RESULTS

Fifty cSLE patients were studied, with a median follow-up of 3.1 years. Each patient reached aLLDAS and cLLDAS at least once. Mean time to reach first aLLDAS/cLLDAS was 8.2/9.0 months, respectively. For 22/42 patients the mean steroid-dose related delay to reach first cLLDAS was 6.2 months. 58% of patients were able to maintain cLLDAS-50. Time to first cLLDAS (OR 0.8, p = 0.013) and higher number of flares (OR 0.374, p = 0.03) were negative predictors to maintain cLLDAS-50. Damage occurred in 34% of patients (23.5% steroid-related), in 64.7% within one year after diagnosis. African/Afro-Caribbean ethnicity, neuropsychiatric involvement and ever use of a biologic were significant predictors for damage.

CONCLUSION

Time to reach cLLDAS in cSLE differs from time to (a)LLDAS, which validates the new cLLDAS definition. Attaining cLLDAS-50 was difficult in real-life. This cohort shows the high risk for early damage in cSLE. T2T with earlier focus on steroid-tapering and starting steroid-sparing drugs seems important to prevent (steroid-related) damage in cSLE.

Targeting DORIS Remission and LLDAS in SLE: A Review

Remission is the established therapeutic goal for patients with systemic lupus erythematosus (SLE) and is currently defined by the widely adopted Definition Of Remission In SLE (DORIS) criteria. Attainment of remission is rare in the clinical setting, thus an alternative, pragmatic treatment target of low disease activity, as defined by the Lupus Low Disease Activity State (LLDAS), provides a less stringent and more attainable treatment goal for a wider proportion of patients compared with DORIS remission. Randomized controlled trials and real-world analyses have confirmed the positive clinical benefits of achieving either DORIS remission or LLDAS. The treat-to-target (T2T) approach utilizes practical clinical targets to proactively tailor individual treatment regimens. Studies in other chronic inflammatory diseases using the T2T approach demonstrated significantly improved clinical outcomes and quality-of-life measures compared with established standard of care. However, such trials have not yet been performed in patients with SLE. Here we review the evolution of DORIS remission and LLDAS definitions and the evidence supporting the positive clinical outcomes following DORIS remission or LLDAS attainment, before discussing considerations for implementation of these outcome measures as potential T2T objectives. Adoption of DORIS remission and LLDAS treatment goals may result in favorable patient outcomes compared with established standard of care for patients with SLE.

The effect of systemic lupus erythematosus (SLE) Disease Activity Score and SLE Disease Activity Index 2000-based remission states in patients with SLE on damage accrual

BACKGROUND/OBJECTIVE

This study aimed to compare the effect of the Systemic Lupus Erythematosus Disease Activity Score (SLE-DAS) with the SLE Disease Activity Index 2000 (SLEDAI-2K) remission state on damage accrual.

METHODS

This study classified SLE patients from the Lupus Clinic of the Royal Thai Army (LUCRA) cohort based on the SLE-DAS index, or Boolean-based, and SLEDAI-2K (Doria) remission state. Regression analysis models were constructed to identify predictors of the Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI) during follow-up.

RESULTS

There were 197 patients identified; 97 patients met at least one definition of remission state, and 100 patients were in the non-remission group at enrollment. Of 97 patients, 97 achieved the SLE-DAS index-based definition, 74 achieved the SLE-DAS Boolean-based definition, and 55 achieved the Doria definition. The mean ± SD of follow-up was 4.77 ± 0.6 years. The changes in SDI over time were non-significantly lower in patients who met any definition of remission compared with those who did not. Multivariate analysis revealed that predictive factors for increased SDI were age and baseline SDI ≥ 1. SLE-DAS index, Boolean, and Doria-based definitions of remission at enrollment had no significant risk reduction on SDI compared with the non-remission group (HR 0.7, 95% CI 0.37-1.32, p = .27; HR 0.73, 95% CI 0.37-1.44, p = .37; HR 0.8, 95% CI 0.39-1.65, p = .55, respectively).

CONCLUSIONS

Patients with SLE who achieved remission status according to the SLE-DAS index or SLEDAI-2K definitions did not show any significant difference in damage accrual compared to those who were not in remission.

Advances in the management of systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a severe multisystem autoimmune disease that can cause injury in almost every body system. While considered a classic example of autoimmunity, it is still relatively poorly understood. Treatment with immunosuppressive agents is challenging, as many agents are relatively non-specific, and the underlying disease is characterized by unpredictable flares and remissions. This State of The Art Review provides a comprehensive current summary of systemic lupus erythematosus based on recent literature. In basic and translational science, this summary includes the current state of genetics, epigenetics, differences by ancestry, and updates about the molecular and immunological pathogenesis of systemic lupus erythematosus. In clinical science, the summary includes updates in diagnosis and classification, clinical features and subphenotypes, and current guidelines and strategies for treatment. The paper also provides a comprehensive review of the large number of recent clinical trials in systemic lupus erythematosus. Current knowns and unknowns are presented, and potential directions for the future are suggested. Improved knowledge of immunological pathogenesis and the molecular differences that exist between patients should help to personalize treatment, minimize side effects, and achieve better outcomes in this difficult disease.

Treat-to-Target in Systemic Lupus Erythematosus: Reality or Pipe Dream

Treat-to-target is a therapeutic approach based on adjustments to treatment at set intervals in order to achieve well-defined, clinically relevant targets. This approach has been successfully applied to many chronic conditions, and in rheumatology promising results have emerged for rheumatoid arthritis. For systemic lupus erythematosus (SLE), defining the most meaningful treatment targets has been challenging, due to disease complexity and heterogeneity. Control of disease activity, the reduction of damage accrual and the patient's quality of life should be considered as the main targets in SLE, and several new drugs are emerging to achieve these targets. This review is focused on describing the target to achieve in SLE and the methods to do so, and it is also aimed at discussing if treat-to-target could be a promising approach also for this complex disease.

Treat to target in Behcet's disease: Should we follow the paradigm of other systemic rheumatic diseases?

During the last decades the efficacy of biologic agents, mainly of anti-TNFs, in controlling the activity of serious manifestations of Behcet's Disease (BD) has been established. On the other hand, the clinical heterogeneity of BD has precluded the validation of a widely-accepted composite index for disease assessment and for target disease-state definitions, such as low disease activity and remission, and the testing of their implementation in clinical practice. Therefore, in contrast to other systemic rheumatic diseases, a treat-to-target strategy has not yet been developed in BD. There are several challenges towards this approach, including standardization of outcome measures for assessing the disease activity in each-affected organ and construction of a composite disease activity index. The challenges for the development of a treat-to-target strategy and possible solutions are discussed in this position paper, which stemmed from a round table discussion that took place in the 19th International Conference on BD.

Treat-to-target in systemic lupus erythematosus: advancing towards its implementation

The treat-to-target (T2T) concept has improved outcomes for patients with diabetes, hypertension and rheumatoid arthritis. This therapeutic strategy involves choosing a well-defined, relevant target, taking therapeutic steps, evaluating whether the target has been achieved, and taking action if it has not. The T2T principle has been embraced by systemic lupus erythematosus (SLE) experts, but measurable and achievable outcomes, and therapeutic options, are needed to make this approach possible in practice. Considerable evidence has been generated regarding meaningful 'state' outcomes for SLE. Low disease activity has been defined and studied, and the most aspirational goal, remission, has been defined by the Definition of Remission in SLE task force. By contrast, current therapeutic options in SLE are limited, and more effective and safer therapies are urgently needed. Fortunately, clinical trial activity in SLE has been unprecedented, and encouraging results have been seen for novel therapies, including biologic and small-molecule agents. Thus, with the expected advent of such treatments, it is likely that sufficiently diverse therapies for SLE will be available in the foreseeable future, allowing the routine implementation of T2T approaches in the care of patients with SLE.
