Living with systemic lupus erythematosus in 2020: a European patient survey

Clinical characteristics and risk factors for lupus flares in sub-Saharan Africa-retrospective cross-sectional study

Systemic lupus erythematosus (SLE) is an autoimmune disease with a variable course with unpredictable flares. Identifying predictors of these flares is essential for monitoring and timely hospital care. To characterize the prevalence of flares within the first five years of SLE diagnosis and determine the clinical and immunological characteristics associated with flare development among patients attending the Rheumatology Clinic at Tikur Anbesa Specialized Hospital (TASH) and Lancet General Hospital. A multicenter, cross-sectional study was conducted from May 2023 to November 2023 at TASH and Lancet General Hospital. The data was collected from electronic medical records and analyzed using SPSS version 26. Logistic regressions were used to determine factors associated with lupus flare. Most patients with SLE were female (95.4%). The most common clinical presentations were musculoskeletal (71.8%), cutaneous (55%), and constitutional (22%). Almost half (44.3%) of the patients had comorbidity illness. Positive ANA test was found in 96.5% of the patients, whereas only 55% had positive anti-dsDNA test. The prevalence of SLE flare in the first five years of SLE diagnosis was 38.9%, and most flares occurred within the first year of diagnosis. Patients with the following characteristics were more likely to have flare-ups: younger age at diagnosis (less than 25 years old), initial presentation with vasculitis, renal flare, and being on low-dose prednisolone. The most common clinical presentations were musculoskeletal, dermatologic, and constitutional manifestations. Age < 25 years at diagnosis, initial clinical presentation with renal manifestation, and being on low-dose prednisolone were predictors of SLE flare. Key Points • This study found a significant gender disparity, with 95% female. • Nearly 39% of patients experienced an SLE flare within the first five years of diagnosis. • Over three-quarters (77%) of flares occurred within the first year of diagnosis. • Age less than 25 years, initial presentation with vasculitis, renal involvement, and being on low-dose prednisolone were identified as predictors of flares.

Anifrolumab treatment improves patient-reported quality of life and decreases disease activity and corticosteroid use in patients with systemic lupus erythematosus: A qualitative study in Denmark

Anifrolumab is a new therapeutic approach for individuals with systemic lupus erythematosus (SLE) directed at blocking the type 1 interferon pathway. Despite the expanding body of literature on Anifrolumab, an essential aspect remains absent: the subjective patient experience of treatment effects and implications on patients' health-related quality of life (HRQoL). The present study aimed to fill this void by elucidating the nuanced perspectives of SLE patients receiving Anifrolumab treatment by conducting qualitative in-depth interviews (IDIs). SLE patients at Aarhus University Hospital who had received at least three infusions of Anifrolumab were approached for inclusion in the study, which comprised two main elements: (1) qualitative IDIs and (2) collection of patient data from electronic medical records (EMRs). The IDIs were semi-structured and based on a discussion guide that included open-ended and close-ended questions. Verbatim transcripts were coded and analysed using qualitative software to understand concepts important to patients and to understand patients' own experiences before and after Anifrolumab therapy. A clinical chart review was conducted using EMR data at baseline, 3 months, and 6 months after Anifrolumab initiation. IDIs were completed with 14 patients, and EMR data was collected from 16 patients (treatment days range: 62-474). Of the 23 symptoms spontaneously reported by patients prior to Anifrolumab treatment, fatigue, joint pain, sun sensitivity, joint stiffness, skin rashes, and hair loss were the most common. Most symptoms improved, and none worsened during treatment. Patients reported significant impacts of disease on daily life before treatment: day-to-day activities, social life, emotional aspects, physical activity, concentration/memory, work/employment, and family/romantic relationships. Patients reported improvements in all aspects after treatment but were still impacted. From the EMR data, we observed a fall in disease activity after treatment initiation with a concomitant reduction in the use of corticosteroids. This study provides valuable insights into the subjective experiences of SLE patients treated with Anifrolumab, and the findings collectively contribute to a comprehensive understanding of the treatment's efficacy from the patients' perspective and its tangible effects on both subjective and objective parameters in SLE patients.

Changes in the incidence and prevalence of systemic lupus erythematosus between 1990 and 2020: an observational study using the Clinical Practice Research Datalink (CPRD)

OBJECTIVE

To obtain updated estimates on the incidence and prevalence of systemic lupus erythematosus (SLE) in the UK, over the period 1990-2020, using the Clinical Practice Research Datalink (CPRD).

METHODS

This was a retrospective cohort study using the CPRD covering the period 1990-2020. A case ascertainment algorithm was developed in line with best practice recommendations for observational research. Incidence was calculated per 100 000 person-years and point prevalence (at the mid-year point) calculated per 100 000. Results were stratified by sex.

RESULTS

9443 SLE cases were identified. 5278 incident cases were identified (4538 women, 740 men). The overall incidence rate was 5.47 (95% CI 5.33 to 5.62) cases per 100 000 person-years. Incidence rates decreased slightly across the study period, which was more pronounced for women than men. Point prevalence increased over time, from 21.4 (95% CI 17.68 to 25.67) per 100 000 in 1990 to 107.14 (95% CI 103.26 to 111.12) per 100 000 in 2020.

CONCLUSIONS

The observed fivefold increase in prevalence of SLE over the last 30 years, in the context of a modest decline in incidence rate, may suggest improved outcomes in SLE and has important implications for healthcare service delivery and planning in the UK.

Misdiagnosis, Missed Diagnosis, and Delayed Diagnosis of Lupus: A Qualitative Study of Rheumatologists

OBJECTIVE

Diagnostic errors in outpatient settings lead to significant consequences, especially in rare diseases such as systemic lupus erythematosus (SLE). A recent vignette-based experimental study revealed that demographic factors influenced rheumatologists' diagnoses of SLE, raising concerns about potential diagnostic biases. We conducted a qualitative study to contextualize these results to generate insights about diagnostic challenges and biases, and root causes.

METHODS

We conducted 41 semistructured interviews among US rheumatologists. Transcripts were independently coded by at least two coders using a hybrid deductive-inductive approach and thematic analysis. A team of four researchers reviewed and defined themes collectively, and also resolved any discrepancies.

RESULTS

Participants were 66% women, and 49% had more than10 years of postfellowship experience. Five major themes were generated, including receiving training through the lens of race or sex, the role of the documented epidemiology of SLE, pattern recognition and test-taking strategies, patient vignettes as an imperfect proxy for patient interactions, and varied consequences to patients from diagnostic bias. Participants noted that the consequences of diagnostic bias could include progressed disease from delayed diagnosis, unnecessary and inappropriate treatment due to missed diagnosis or misdiagnosis, and increased cost and harm.

CONCLUSION

This study underscores the unique challenges of diagnosing SLE, with complex factors contributing to diagnosis bias and delays. Interventions during medical education could prevent downstream diagnostic biases. Future research should explore interventions to mitigate diagnostic bias and refine vignettes to better mirror real-world clinical scenarios. Understanding diagnostic bias in SLE is crucial for improving patient outcomes and refining medical training practices.

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.

Challenges and opportunities in access to care for systemic lupus erythematosus patients across Europe and worldwide

SLE presents significant challenges for patients and health-care professionals (HCPs), both across Europe and worldwide. Improving health-care outcomes for patients with SLE requires a comprehensive understanding of patient disease pathways. In particular, the geographical distance between SLE patients and specialized care centres, combined with the scarcity of rheumatologists, exacerbates delays in diagnosis and management. Also, the initial SLE symptoms can often be non-specific, and providing guidelines for primary HCPs and other non-specialists is extremely important. Improvement in access to treatment is also important, with several recently approved therapies for SLE not being available in several European countries and many low- and middle-income countries (LMICs). Furthermore, in the LMICs in which these treatments are available, they are not always covered by the health-care system, making their access almost impossible for those of lower socio-economic status. A number of provisions are already in place within the European Union, to improve access to care for patients with rare and complex diseases, including those with SLE. In particular, European Reference Networks (ERNs), such the ERN for Autoimmune Diseases ReCONNET, are virtual networks involving HCPs across Europe with the aim of improving the care of patients with rare and complex diseases that require highly specialized treatment and a concentration of knowledge and resources. In addition, lupus patient organizations such as Lupus Europe play a crucial role in raising awareness of SLE and advocating for improved access to care. Together, we can work towards a future where all people living with lupus receive the comprehensive and timely care they deserve.

Systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disease characterised by the presence of autoantibodies towards nuclear antigens, immune complex deposition, and chronic inflammation at classic target organs such as skin, joints, and kidneys. Despite substantial advances in the diagnosis and management of SLE, the burden of disease remains high. It is important to appreciate the typical presentations and the diagnostic process to facilitate early referral and diagnosis for patients. In most patients, constitutional, mucocutaneous, and musculoskeletal symptoms represent the earliest complaints; these symptoms can include fatigue, lupus-specific rash, mouth ulcers, alopecia, joint pain, and myalgia. In this Seminar we will discuss a diagnostic approach to symptoms in light of the latest classification criteria, which include a systematic evaluation of clinical manifestations (weighted within each domain) and autoantibody profiles (such as anti-double-stranded DNA, anti-Sm, hypocomplementaemia, or antiphospholipid antibodies). Non-pharmacotherapy management is tailored to the individual, with specific lifestyle interventions and patient education to improve quality of life and medication (such as hydroxychloroquine or immunosuppressant) adherence. In the last decade, there have been a few major breakthroughs in approved treatments for SLE and lupus nephritis, such as belimumab, anifrolumab, and voclosporin. However the disease course remains variable and mortality unacceptably high. Access to these expensive medications has also been restricted across different regions of the world. Nonetheless, understanding of treatment goals and strategies has improved. We recognise that the main goal of treatment is the achievement of remission or low disease activity. Comorbidities due to both disease activity and treatment adverse effects, especially infections, osteoporosis, and cardiovascular disease, necessitate vigilant prevention and management strategies. Tailoring treatment options to achieve remission, while balancing treatment-related comorbidities, are priority areas of SLE management.

A case-control study on health-related quality of life of systemic lupus erythematosus patients

Systemic lupus erythematosus (SLE) is a chronic rheumatic autoimmune condition that can cause a wide range of symptoms and problems that may affect the health-related quality of life. The main objective of the study was to assess the SLE burden by exploring the effect of the disease on health-related quality of life. The study consisted of 29 female SLE patients and 27 healthy female controls; they were matched for age and parity. A 36-item Short Form health survey questionnaire (SF-36) was used to collect data from participants through face-to-face interviews and to assess their health-related quality of life. SF-36 summary scores for the physical and mental components were decreased in the studied patients compared with controls; PCS was 28.81 ± 16.63, 77.25 ± 15.75 for cases and controls, respectively; and MCS was 32.75 ± 18.69, and 78.75 ± 10.63 for cases and controls, respectively (p < 0.05). The high correlation between the two dimensions characterizes this decrease. SLE negatively affected the quality of life of the patients. Measures such as lifestyle modifications, physical activity, and a healthy diet should be taken to improve the health-related quality of life in SLE patients. In addition, raising the patient's awareness about the disease and its consequences could help to cope with the illness and engage in social and physical activities.

Evaluating the Interaction Between Pain Intensity and Resilience on the Impact of Pain in the Lives of People With Fibromyalgia

OBJECTIVE

Recent theoretical models posit that resilience acts as a resource/mechanism opposing pain catastrophizing and other vulnerability sources against pain adaptation. The aim of this study was to investigate the relationship between resilience, pain, and functionality in people living with fibromyalgia (FM).

MATERIALS AND METHODS

We conducted a cross-sectional online survey of people participating in Brazilian fibromyalgia virtual support groups on Facebook in May 2018. Resilience was evaluated by the Connor-Davidson Resilience Scale. Average pain and the degree of interference of pain in the lives of participants (DIPLP) were assessed using the Brief Pain Inventory. The association between these 3 variables was evaluated through multivariable robust linear regression with adjustment for 21 potential confounders.

RESULTS

We included 2176 participants with FM. Resilience was associated with a decreased DIPLP (β: -0.38, 95% CI: -0.54 to -0.22, P <0.001) but not with average pain scores (β: -0.01, 95% CI: -0.18 to 0.16, P =0.93). A significant interaction between resilience and average levels of pain on the DIPLP was observed so that resilience showed a much stronger protective association among participants with average null-to-mild pain than among those with moderate and severe pain levels.

DISCUSSION

Our results provide evidence against beliefs that the pain of people with FM is related to low psychological resilience and shed light on the complex interrelationships between resilience, pain, and functionality. This research signals both the relevance and limits of resilience in the management of FM. Future studies evaluating behavioral interventions for FM should consider how those interventions interact with baseline pain levels and resilience.

SLE criteria are by necessity still based on clinical (and immunological) criteria items

INTRODUCTION

The 2019 European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) classification criteria for systemic lupus erythematosus (SLE) rely on clinical and routine immunological items. The criteria have anti-nuclear antibodies (ANA) as an obligatory entry criterion; items are weighted and ordered in domains. While demonstrating good sensitivity and specificity, the lack of a more molecular approach to some came as a disappointment.

AREAS COVERED

Based on a non-systematic literature search, this review covers items investigated in the EULAR/ACR classification criteria project, but not included in the set of criteria. It demonstrates data on the importance of the criteria and analyses implications of multiomics studies started around the same time as the criteria project. We also discuss data on the type-I interferon signature and on other cytokines, as well as on complement proteins and their split products. The final part deals with the variability in disease and the apparently random pattern of autoantibodies and organ manifestations in individual patients.

EXPERT OPINION

We believe that the EULAR/ACR criteria are a relevant step toward the right direction. A more uniform molecular approach will not be feasible as long as the molecular mechanisms underlying the tendency toward producing multiple autoantibodies are not better understood.

Therapeutic Drug Monitoring in Patients with Systemic Lupus Erythematosus: Utility and Gaps

Despite advances in the treatment of patients with systemic lupus erythematous (SLE), outcomes have remained suboptimal. Persistent disease activity, patient comorbidities and drug toxicities contribute to the accrual of progressive irreversible damage and high rates of morbidity and mortality. Currently, similar drug doses and regimens are promulgated in the treatment guidelines for all SLE patients, despite the vast differences in patient and environmental factors that affect the drugs' metabolism and blood concentrations. This causes a disconnect between drug dosing and drug blood concentrations, which can then result in unpredictability in drug toxicities and therapeutic effects. In this review, we discuss commonly used oral immunosuppressive medications in SLE, their pharmacogenomics, and factors affecting their metabolism and blood concentrations. Further, we highlight the role of therapeutic drug monitoring in SLE, which is the first accessible step to individualising therapy.

Assessment and personalised advice for fatigue in systemic lupus erythematosus using an innovative digital tool: the Lupus Expert system for the Assessment of Fatigue (LEAF) study

BACKGROUND

Fatigue is reported as the most prevalent symptom by patients with systemic lupus erythematosus (SLE). Fatigue management is complex due to its multifactorial nature. The aim of the study was to assess the usefulness of an innovative digital tool to manage fatigue in SLE, in a completely automated manner.

METHODS

The «Lupus Expert System for Assessment of Fatigue» (LEAF) is free digital tool which measures the intensity and characteristics of fatigue and assesses disease activity, pain, insomnia, anxiety, depression, stress, fibromyalgia and physical activity using validated patient-reported instruments. Then, LEAF automatically provides personalised feedback and recommendations to cope with fatigue.

RESULTS

Between May and November 2022, 1250 participants with SLE were included (95.2% women, median age 43yo (IQR: 34-51)). Significant fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue <34) was reported by 78.9% of patients. In univariate analysis, SLE participants with fatigue were more likely to be women (p=0.01), perceived their disease as more active (p<0.0001), had higher levels of pain (p<0.0001), anxiety (p<0.0001), depression (p<0.0001), insomnia (p<0.0001), stress (p<0.0001) and were more likely to screen for fibromyalgia (p<0.0001), compared with patients without significant fatigue. In multivariable analysis, parameters independently associated with fatigue were insomnia (p=0.0003), pain (p=0.002), fibromyalgia (p=0.008), self-reported active SLE (p=0.02) and stress (p=0.045). 93.2% of the participants found LEAF helpful and 92.3% would recommend it to another patient with SLE.

CONCLUSION

Fatigue is commonly severe in SLE, and associated with insomnia, pain, fibromyalgia and active disease according to patients' perspective. Our study shows the usefulness of an automated digital tool to manage fatigue in SLE.

The communication GAP between patients and clinicians and the importance of patient reported outcomes in Systemic Lupus Erythematosus

Systemic Lupus Erythematosus (SLE) imposes a great burden on the lives of patients. Patients' and physicians' concerns about the disease diverge considerably. Physicians focus on controlling disease activity to prevent damage accrual, while patients focus on symptoms that impact on Health-Related Quality of Life (HRQoL). We explored the physicians' and patients' perspective and the potential role of Patient Reported Outcomes (PROs). Physicians are aware of the theoretical usefulness of PROs to collect information deriving from the patients' perspective. However, they often do not know how to interpret and use these questionnaires in a real shared therapeutic strategy. For the patients, it's important to be seen as a whole person with a true consideration of how they feel and function. Strategies to help bridge the communication gap could include: better use of time during visits, preparing for the consultation, a more understandable lay language used by the doctor, a dedicated nurse.

Uncertainty and its related coping strategies in systemic lupus erythematosus. Life in the fog

BACKGROUND

One of the most prevalent problems of patients with systemic lupus erythematosus (SLE) is the uncertainty over an indefinite future. Uncertainty has significant effects on quality of life. The aim of this study was to explore uncertainty and personal strategies to cope with it among patients with SLE.

MATERIALS AND METHODS

This qualitative study was conducted in 2020-2021 using conventional content analysis. Participants were 21 patients with SLE who were purposefully selected from rheumatology clinics in Kashan, Kerman, and Bandar Abbass in Iran. Data collection was performed using face-to-face, in-depth, semi-structured interviews and was continued up to data saturation. Data were analyzed concurrently with data collection through conventional content analysis approach proposed by Graneheim and Lundman.

RESULTS

Two main themes, namely, "life in the fog" and "attempt to find peace" emerged from patients' experiences of illness uncertainty of SLE. Life in the fog included three main categories of "perception of threat to health", "challenge of doubt and certainty," and "indefinite future." Attempt to find peace included three main categories of "spirituality," "reflection," and "attempt to acquire SLE-related knowledge.

CONCLUSIONS

Uncertainty is a major psychological stress for patients with SLE. Healthcare providers should therefore consider the challenges and concerns faced by patients and, through utilizing appropriate training and communicational practices, plan interventions and strategies to empower patients for coping with uncertainty.

Experiences and Perspectives of Children and Young People Living with Childhood-Onset Systemic Lupus Erythematosus-An Integrative Review

Childhood-onset systemic lupus erythematosus (cSLE) impacts the daily life of children and young people. This study aimed to describe the experiences and perspectives of children and young people living with cSLE. An integrative review guided by Whittemore and Knafl was conducted. Extant empirical research published in peer-reviewed journals from 2000 to 2021 on children's self-reported experiences living with cSLE was identified from Scopus, CINAHL, Medline via PubMed, and PsycINFO via Ovid databases. Nineteen studies involving over 1400 participants were included. Four themes and fourteen sub-themes were identified: (1) challenging symptoms (disruptions to life and altered self, severity, fatigue, depression, and anxiety), (2) medicines and side effects (dreaded steroids, conflicting feelings, and medication adherence), (3) complicated life (school sports and social, giving things up, lack of understanding, and quality of life) and (4) ways of coping (family and friends, relationships with health providers, and maintaining positivity). While cSLE shares many similarities with adult-onset SLE, awareness of differences in experiences and perceptions of children and young people is crucial. The significant psychological and social impact of the disease and its treatments necessitates a comprehensive, holistic approach to managing cSLE that considers the unique needs of youth.

Patient-reported disease impact of systemic lupus erythematosus with active joint symptoms: Results from the systemic lupus erythematosus-update survey

BACKGROUND

Many people with systemic lupus erythematosus (SLE) experience joint pain, swelling, and stiffness. These joint symptoms are associated with problems in physical functioning and work disability. We used survey data from adults with SLE to explore the burden and impact of joint symptoms.

METHODS

SLE-UPDATE was a 2019 cross-sectional US survey of adults with SLE. We compared respondents with "currently active" joint symptoms' and those "without currently active" joint symptoms. The active joint cohort comprised survey respondents who self-reported current "stiffness in joints" or "pain/swelling in joints" and who had moderate to severe joint pain (Worst Joint Pain Numeric Rating Scale [NRS] score ≥ 4). Respondents not fulfilling these criteria were included in the non-active joint cohort. Outcomes included frequency and severity of pain, patient-reported outcomes (LupusPRO™ and Work Productivity and Activity Impairment: Lupus [WPAI-Lupus]), satisfaction with current treatments, and importance of different treatment goals.

RESULTS

More respondents in the active joint cohort (N = 285) than in the non-active joint cohort (N = 215) reported pain most or all the time over the preceding 7 days (77.5% vs. 32.1%, p < .0001), fibromyalgia (45% vs. 12%, p < .0001), and higher (worse) mean scores on the Worst Pain NRS (6.5 vs. 4.8, p < .0001) and Worst Joint Pain NRS (6.7 vs. 4.5, p < .0001). Mean Lupus PRO health-related quality of life (HRQoL) total score was lower (worse) in the active joint cohort (48.9 vs. 64.1, p < .0001). WPAI-Lupus scores indicated greater work productivity losses and activity impairment in the active joint cohort. More respondents in the active joint cohort than in the non-active joint cohort were neutral or not satisfied with current treatments and rated reducing pain as a "very important" treatment goal (26.7% vs. 18.1%).

CONCLUSIONS

Respondents with SLE and active joint manifestations in addition to having more pain report lower HRQoL and were less satisfied with their current treatments. Comorbid fibromyalgia may play a role in joint symptoms in patient with SLE joint manifestations. There is an unmet need for new therapeutic options to reduce joint symptom burden among patients with SLE.

Role of autotaxin in systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a prototypic systemic autoimmune disease characterized by the production of various autoantibodies and deposition of immune complexes. SLE is a heterogenous disease, and the pattern of organ involvement and response to treatment differs significantly among patients. Novel biological markers are necessary to assess the extent of organ involvement and predict treatment response in SLE. Lysophosphatidic acid is a lysophospholipid involved in various biological processes, and autotaxin (ATX), which catalyzes the production of lysophosphatidic acid in the extracellular space, has gained attention in various diseases as a potential biomarker. The concentration of ATX is increased in the serum and urine of patients with SLE and lupus nephritis. Recent evidence suggests that ATX produced by plasmacytoid dendritic cells may play an important role in the immune system and pathogenesis of SLE. Furthermore, the production of ATX is associated with type I interferons, a key cytokine in SLE pathogenesis, and ATX may be a potential biomarker and key molecule in SLE.

Lupus spectrum ambiguity has long-term negative implications for patients

Lupus is a complex disease that is often difficult to diagnose. Risks of diagnostic delays include non-specific signs and symptoms that mimic other diseases and a lack of diagnostic criteria and referral pathways for non-specialists. To address these issues, we convened a series of virtual meetings with members of our Addressing Lupus Pillars for Health Advancement clinical care team. Meeting participants included lupus physicians, treatment developers from biotechnology, patient advocacy group representatives from the Lupus Foundation of America and advocacy/government consultants. Causes and consequences of ambiguity in diagnosis and diagnostic delays were evaluated through historical, experiential and evidence-based accounts (survey data, literature reviews and patient testimonials). Discussions highlighted the need for a clearer understanding of the definition of lupus, the natural history of the disease and the need for advancements in biotechnology to support an accurate and timely diagnosis with the potential development of a lupus spectrum.

Determinants of health-related quality of life across the spectrum of connective tissue diseases using latent profile analysis: Results from the LEAP cohort

OBJECTIVES

Poor health-related quality of life (HR-QoL) is well recognised in patients with connective tissue diseases (CTD). We hypothesised that subgroups of patients across the spectrum of CTD experience different HR-QoL patterns, and aimed to determine patient-level characteristics associated with these different subgroups.

METHODS

Using the eight continuous domains of the Medical Outcomes Study Short-Form 36 (SF-36) questionnaire we performed data-driven clustering to derive latent profiles (LP) of patients with distinct HR-QoL patterns. Multivariable ordinal logistic regression was used to determine patient-level characteristics associated with each HR-QoL subgroup identified.

RESULTS

309 CTD patients completed the SF-36 questionnaire. The most impaired SF-36 domains in each disease group were vitality, general health and bodily pain. The physical component of the SF-36 was consistently more impaired compared with the mental component, with similar scores across disease groups.Three latent profiles were identified with poor (n = 89; 29%), average (n = 190; 61.4%) and excellent (n = 30; 9.7%) HR-QoL. LP were not associated with diagnostic grouping or autoantibody profiles. Black background (OR 0.22 [95% CI 0.08-0.63]), Indo-Asian background (0.39 [0.19-0.78]), concomitant fibromyalgia (0.40 [0.20-0.78]), sicca symptoms (0.56 [0.32-0.98]) and multi-morbidity (Charlson Comorbidity Index, 0.81 [0.67-0.97]) were associated with the 'poor' HR-QoL LP.

CONCLUSION

Distinct HR-QoL subgroups exist that are not primarily driven by the specific diagnosis or autoantibody profiles. We identified a number of key demographic and clinical factors associated with poor HR-QoL. These factors need to be addressed across the whole CTD spectrum as part of a holistic management approach aimed at improving overall patient outcomes.

State of the art and future directions in assessing the quality of life in rare and complex connective tissue and musculoskeletal diseases

Background

As chronic conditions, rare and complex connective tissue and musculoskeletal diseases (rCTDs) significantly affect the quality of life generating an impact on the physical, psychological, social, and economic dimensions of the patients' lives, having implications on the family, changing the lifestyle and interpersonal relationships. Traditionally, generic and disease-specific measures for Quality of Life (QoL) provide valuable information to clinicians since QoL affects healthcare services utilization, predicts morbidities and mortalities, workability, etc. Moreover, the assessment of unmet clinical needs, satisfaction, the experience with the treatment and the care, the psychological dimensions, and the effects of the diseases, such as fatigue, could represent valuable dimensions to be considered in the QoL impact assessment. It is also necessary to measure the impact of rCTDs by considering the perspectives of family members/informal caregivers, for instance considering values, beliefs, experiences, life circumstances, psychological aspects, family relationships, economic issues, changes in social activities, etc.

Objective

The aim of this scoping review is to better understand the status of QoL metrics used in clinical and economic research for the assessment of the individual's perspective on living with rCTDs.

Research question

What are the main challenges in QoL measures (and/or) measurement/assessment in rCTDs?

Materials and methods

Scoping review of the literature referring to QoL measures in rCTDs. Database: PUBMED, ISI-Web of Science; last date: 21/09/2021.

Results

Anxiety and depression, body image satisfaction, daily activity, fatigue, illness perception, pain, personality, QoL, resilience, satisfaction with the relationship, self-management, sexual QoL, sleep quality, social support, stress, uncertainty, and work productivity are the observed dimensions covered by the included studies. However, "more shadows than lights" can summarize the review's outcome in terms of Patient Reported Outcome Measures (PROMs) domains covered for each of the rCTDs. Also, for those diseases characterized by a relatively high prevalence and incidence, such as Systemic Lupus Erythematosus, Sjögren's Syndrome, and Systemic Sclerosis, the analysis of patients' resilience, satisfaction with the quality of the relationship, personality, and stress are still missing dimensions. It has been observed how reducing items, increasing the number of domains, and disease-specific questionnaires characterize the "technological trajectory," such as the evolution of questionnaires' characteristics for assessing QoL and QoL-related dimensions and the burden of rCTDs.

Conclusion

The scoping review presents an overview of studies focused on questionnaires used to evaluate the different dimensions of quality of life in terms of general instruments and disease-specific questionnaires. Future research should include the co-design with patients, caregivers, and patient representatives to create questionnaires focused on the unmet needs of people living with rCTDs.

Fatigue is independently associated with disease activity assessed using the Physician Global Assessment but not the SLEDAI in patients with systemic lupus erythematosus

OBJECTIVES

To analyse whether reported fatigue, one of the most challenging manifestations of systemic lupus erythematosus (SLE), may bias the assessment of disease activity in SLE according to the Physician Global Assessment (PGA).

METHODS

Patients from the Lupus BioBank of the upper Rhein database, a cross-sectional multicentre collection of detailed clinical and biological data from patients with SLE, were included. Patients had to fulfil the 1997 American College of Rheumatology criteria for SLE and the PGA (0-3 scale) at the time of inclusion had to be available. Fatigue was assessed according to the Fatigue Scale for Motor and Cognitive Functions. Univariate and multivariate regression models were built to determine which variables were associated with the PGA.

RESULTS

A total of 350 patients (89% female; median age: 42 years, IQR: 34-52) were included. The median Safety of Estrogens in Lupus Erythematosus National Assessment-Systemic Lupus Erythematosus Disease Activity Index (SELENA-SLEDAI) score was 4 (IQR: 2-6). Of these 350 patients, 257 (73%) reported significant fatigue. The PGA (p=0.004) but not the SELENA-SLEDAI (p=0.43) was significantly associated with fatigue. Both fatigue and SELENA-SLEDAI were independently associated with the PGA in two different multivariate models.

CONCLUSION

Fatigue is independently associated with disease activity assessed using the PGA but not the SLEDAI. These findings highlight the fact that the PGA should capture only objectively active disease manifestations in order to improve its reliability.

Association of Clinical Manifestations of Systemic Lupus Erythematosus and Complementary Therapy Use in Taiwanese Female Patients: A Cross-Sectional Study

Background and Objectives: Systemic lupus erythematosus (SLE) is a chronic systemic autoimmune disease that affects predominantly women in the childbearing years. Patients may seek complementary therapies to manage their health and to reduce symptoms. However, to our knowledge, no studies have explored the association between clinical manifestations of SLE and complementary therapies. Therefore, this study aimed to investigate the association of complementary therapies with common clinical manifestations in Taiwanese female patients with SLE. Materials and Methods: A cross-sectional study was conducted at a regional teaching hospital in southern Taiwan. Outpatients from the rheumatology clinic who met the inclusion criteria were consecutively recruited. Demographic data, clinical manifestations of SLE, and types of complementary therapy use were determined using paper-based questionnaire. Multiple logistic regression analyses were conducted to investigate the use of complementary therapies associated with clinical manifestations of SLE. Results: Of the 317 female patients with SLE, 60.9% were 40 years or older. The five SLE clinical manifestations with the highest prevalence were Raynaud’s phenomenon (61.2%), photosensitivity (50.2%), Sjögren’s syndrome (28.4%), arthralgia and arthritis (22.1%), and renal involvement (14.5%). Multiple logistic regression analyses revealed that Raynaud’s phenomenon was significantly associated with fitness walking or strolling (adjusted odds ratio [aOR] 1.77; p = 0.027) and fish oil supplements (aOR 3.55, p < 0.001). Photosensitivity was significantly and inversely associated with the use of probiotics (aOR 0.49; p = 0.019). Renal involvement was significantly associated with the use of probiotics (aOR 2.43; p = 0.026) and visit to the Chinese medicine department in a hospital (aOR 3.14, p = 0.026). Conclusions: We found that different clinical manifestations of SLE were associated with the use of different complementary therapies. Health care providers should have up-to-date knowledge of common complementary therapies and be ready to provide evidence-based advice to patients with SLE.

Treatment Patterns and Clinical Characteristics of Patients with Systemic Lupus Erythematosus and Musculoskeletal Symptoms: A Retrospective, Observational Study

INTRODUCTION

Musculoskeletal (MSK) symptoms, including arthritis and arthralgia, are common manifestations of systemic lupus erythematosus (SLE); definitions of activity patterns in SLE differ across studies. This study described clinical characteristics and treatment patterns of patients with SLE-MSK over time and by disease activity patterns from a real-world setting.

METHODS

This retrospective descriptive analysis includes a subset of patients with SLE from the Hopkins Lupus Cohort with identified MSK involvement by scores on the arthritis domain of the Safety of Estrogens in Systemic Lupus Erythematosus National Assessment-Systemic Lupus Erythematosus Disease Activity Index (SELENA-SLEDAI) or Lupus Activity Index. Clinical characteristics and treatment patterns were described for patients with at least two visits over the observation period (2010-2019) for the SLE-MSK population based on three disease activity patterns: chronically active (MSK-CA), relapsing-remitting (MSK-RR), and long quiescence (MSK-LQ).

RESULTS

The SLE-MSK subpopulation included 664 patients (4069 person-years). The most frequently used medications over the observation period were antimalarials (95%), corticosteroids (92%), immunosuppressants (58%), and nonsteroidal anti-inflammatory drugs (NSAIDs) (48%); 7% of patients used biologics. The highest use of corticosteroids was in the MSK-CA group (90.5% of follow-up time), followed by MSK- RR (83.9%), and MSK-LQ (46.5%). Mean prednisone dose was significantly higher in MSK-RR (8.5 mg) compared to MSK-CA (6.5 mg).

CONCLUSIONS

This descriptive analysis highlights the impact of prevalent manifestations such as arthritis on the chronic use of corticosteroids, immunosuppressants, and NSAIDs to manage disease activity in patients with SLE, suggesting there is a need for new therapeutic options that enable a lower use of medication when treating lupus.

Improving patient pathways for systemic lupus erythematosus: a multistakeholder pathway optimisation study

Objective

Among the most significant challenges in SLE are the excessive diagnosis delay and the lack of coordinated care. The aim of the study was to investigate patient pathways in SLE in order to improve clinical and organisational challenges in the management of those with suspected and confirmed SLE.

Methods

We conducted a cross-sectional study of patients with SLE, healthcare providers and other representative stakeholders. Focus groups were conducted, and based on the collected data the most impactful disruption points in SLE patient pathways were identified. A novel framework to improve individual patient pathways in SLE was developed, discussed and validated during a consensus meeting with representative stakeholders.

Results

Six thematic clusters regarding disruption in optimal patient pathways in SLE were identified: appropriate and timely referral strategy for SLE diagnosis; the need for a dedicated consultation during which the diagnosis of SLE would be announced, and following which clarifications and psychological support offered; individualised patient pathways with coordinated care based on organ involvement, disease severity and patient preference; improved therapeutic patient education; prevention of complications such as infections, osteoporosis and cancer; and additional patient support. During the consensus meeting, the broader panel of stakeholders achieved consensus on these attributes and a framework for optimising SLE patient pathways was developed.

Conclusions

We have identified significant disruption points and developed a novel conceptual framework to improve individual patient pathways in SLE. These data may be of valuable interest to patients with SLE, their physicians, health organisations as well as policy makers.

Coping with systemic lupus erythematosus in patients' words

OBJECTIVE

Previous research on coping strategies of patients with SLE showed that there are no absolute adaptive or maladaptive strategies and that the range of potential coping strategies is large and heterogeneous. In this paper, we aimed to identify, in a large sample of patients with SLE (N=3222), the most frequent words used by patients to describe their coping strategies, to group them into significant themes and to test their possible association with specific patient characteristics.

METHODS

Our analyses were based on the data set of the European survey 'Living with Lupus in 2020' (N=3222). Through the T-LAB software, we analysed the answers that adult participants gave to an open-ended question about how they cope with the disease. We identified the most frequent words, and with hierarchical cluster analysis we grouped them into semantic clusters (ie, themes) that were characterised by specific patterns of words. Finally, we tested the possible association between clusters and illustrative variables (sociodemographics, disease characteristics, quality of life).

RESULTS

Five coping strategies were identified, each of them constituting an important percentage of the total word occurrences: positive attitude (22.58%), social support (25.46%), medical treatments (10.77%), healthy habits (20.74%) and avoid stress (20.45%). Each strategy was statistically associated with specific patient characteristics, such as age and organ involvement.

CONCLUSIONS

Learning to adapt to a lifetime of having SLE may require replacing old coping strategies with more effective ones. Investigating patients' coping strategies in relation to different patient characteristics represents a useful starting point for developing more targeted and efficacious interventions.

Difficulties and Psychological Impact of the SARS-CoV-2 Pandemic in Patients with Systemic Lupus Erythematosus: A Nationwide Patient Association Study

OBJECTIVES

We aimed to evaluate the difficulties encountered by systemic lupus erythematosus (SLE) patients during the early COVID-19 pandemic and to evaluate their impact on patient mental health.

METHODS

We conducted a nationwide survey including SLE patients from France, recruited by their treating specialist or through a patient association. The survey was administered online or in paper form between November 2020 and April 2021 and included questions aiming at evaluating the difficulties encountered during the early COVID-19 pandemic (March to August 2020). The impact on mental health was evaluated using the Hospital Anxiety and Depression Scale (HADS) and the Post-Traumatic Stress Disorder (PTSD) Checklist for DSM-5 (PCL-5).

RESULTS

536 SLE patients (91.9% women) of mean age 50 (±14.1) years responded to the survey. The main reported difficulties were issues regarding access to medical care (n = 136, 25.4%) or hydroxychloroquine treatment (n = 98/389, 25.2%), the loss of employment (n = 85/349, 24.4%), and financial difficulties (n = 75/536, 11%). In 328 patients with complete mental health assessments, 161 (47.2%) screened positive for anxiety, 141 (41.2%) screened positive for depressive syndrome, and 128 (38.7%) screened positive for PTSD. The multivariate analysis showed that female sex (OR = 4.29 [95%CI: 1.39-13.24]), financial issues (OR = 2.57 [1.27-5.22]), and difficulties accessing medical care (OR = 2.15 [1.26-3.69]) or hydroxychloroquine treatment (OR = 1.90 [1.06-3.40]) were independently associated with a positive screening for PTSD.

CONCLUSIONS

The COVID-19 pandemic resulted in a severe burden in SLE patients, including difficulties accessing care and treatment along with high psychological distress. Better understanding these difficulties will allow for better prevention and care in times of crisis.

Fatigue in Systemic Lupus Erythematosus: An Update on Its Impact, Determinants and Therapeutic Management

Fatigue is a complex and multifactorial phenomenon which is often neglected by clinicians. The aim of this review was to analyze the impact, determinants and management of fatigue in patients with Systemic Lupus Erythematosus (SLE). Fatigue is one of the most prevalent symptoms in SLE, reported by 67% to 90% of patients. It is also described as the most bothersome symptom, considering that it may impair key aspects of health-related quality of life, while also leading to employment disability. It is a multifactorial phenomenon involving psychological factors, pain, lifestyle factors such as reduced physical activity, whereas the contribution of disease activity remains controversial. The management of fatigue in patients with SLE should rely upon a person-centered approach, with targeted interventions. Some pharmacological treatments used to control disease activity have demonstrated beneficial effects upon fatigue and non-pharmacological therapies such as psychological interventions, pain reduction and lifestyle changes, and each of these should be incorporated into fatigue management in SLE.
