Use of Antimalarial Agents is Associated with Favourable Physical Functioning in Patients with Systemic Lupus Erythematosus

Patients with NPSLE experience poorer HRQoL and more fatigue than SLE patients with no neuropsychiatric involvement, irrespective of neuropsychiatric activity

OBJECTIVES

Substantial proportions of patients with SLE report poor health-related quality of life (HRQoL). Our objective was to investigate the impact of neuropsychiatric involvement (NP) in SLE on patient-reported outcomes.

METHODS

We analysed data from four phase III trials (BLISS-52, BLISS-76, BLISS-SC, EMBRACE; N = 2968). The NPSLE group comprised individuals with NP-BILAG A/B/C/D or score in any descriptor of the NP-SLEDAI-2K at baseline (N = 350), while the non-NPSLE group consisted of patients with NP-BILAG E (N = 2618). HRQoL was assessed with the SF-36, EQ-5D-3L, and FACIT-F. Full health state (FHS) was defined as 'no problems' in all EQ-5D dimensions.

RESULTS

NPSLE patients reported lower scores in the SF-36 physical and mental component summary compared with the non-NPSLE population [mean (s.d.): 35.7 (9.1) vs 39.6 (9.6); P < 0.001 and 37.3 (12.1) vs 41.4 (11.0); P < 0.001, respectively]. NPSLE patients also exhibited impaired HRQoL in all EQ-5D dimensions compared with non-NPSLE patients (P < 0.05 for all). A substantially lower proportion of NPSLE patients experienced FHS in comparison with the non-NPSLE group (3.3% vs 14.5%; P < 0.001). NPSLE was associated with severe fatigue [23.8 (12.2) vs 31.5 (11.6); P < 0.001]. Notably, our findings revealed no discernible distinctions between active and inactive NPSLE patients with regard to SF-36, EQ-5D, FHS or FACIT-F scores.

CONCLUSION

NP in patients with SLE has a detrimental effect on HRQoL experience and is associated with severe fatigue, regardless of the degree of neuropsychiatric disease activity. Early intervention is warranted in NPSLE patients to enhance long-term HRQoL experience.

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.

Obesity and tobacco smoking are independently associated with poor patient-reported outcomes in SLE: a cross-sectional study

We investigated associations of obesity and tobacco smoking with health-related quality of life (HRQoL), pain, fatigue, and functional impairment in systemic lupus erythematosus (SLE). Furthermore, we explored whether there was an effect modification between these two factors. We included adult SLE patients from the Linköping University Hospital (n = 325) in the present cross-sectional analysis. We further included population-based controls and performed cardinality matching to balance age and sex distributions with cases (n = 224). HRQoL was assessed with the EQ-5D index score; pain, fatigue, and overall SLE-related health state with visual analogue scales (VAS; 0 [best] to 100 [worst]); and functional impairment with the HAQ-DI. Unacceptable outcomes were defined as VAS scores corresponding to the 90th percentile derived from the matched controls. SLE patients reported worse scores than controls in all measures, and approximately 30% experienced unacceptable outcomes. When compared with normal-weight, obese SLE patients reported lower HRQoL, and greater functional impairment and risk of unacceptable pain (OR: 3.2; 95% CI 1.6-6.7) and fatigue (OR: 2.1; 95% CI 1.0-4.3). Similarly, the current smokers reported higher levels of functional impairment and a greater risk of unacceptable pain (OR: 3.8; 95% CI 1.8-8.2) and fatigue (OR: 2.8; 95% CI 1.3-5.9) than never smokers. The associations were independent of age, sex, disease duration, disease activity, and organ damage. There was no evidence of a synergistic effect between increased BMI and smoking on any outcome. In summary, obesity and smoking are risk factors for unacceptable patient-reported outcomes in SLE, regardless of clinical activity.

Factors associated with non-adherence to medications in systemic lupus erythematosus: Results from a Swedish survey

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.

Belimumab and antimalarials combined against renal flares in patients treated for extra-renal systemic lupus erythematosus: results from 4 phase III clinical trials

OBJECTIVES

To determine the effect of antimalarial agents (AMA) and different doses and pharmaceutical forms of belimumab on preventing renal flares in patients with SLE treated for extra-renal disease.

METHODS

We pooled data from the BLISS-52, BLISS-76, BLISS-SC and BLISS-Northeast Asia trials of belimumab (n = 3225), that included patients with active SLE yet no severe ongoing nephritis. Participants were allocated to receive intravenous belimumab 1 mg/kg, intravenous belimumab 10 mg/kg, subcutaneous belimumab 200 mg, or placebo in addition to standard therapy. We estimated hazards of renal flare development throughout the study follow-up (52-76 weeks) using Cox regression analysis.

RESULTS

In total, 192 patients developed a renal flare after a median of 197 days. Compared with placebo, the risk of renal flares was lower among patients receiving intravenous belimumab 10 mg/kg (HR: 0.62; 95% CI: 0.41, 0.92; P = 0.018) and intravenous belimumab 1 mg/kg (HR: 0.42; 95% CI: 0.22, 0.79; P = 0.007), while no significant association was found for subcutaneous belimumab 200 mg. AMA use yielded a lower hazard of renal flares (HR: 0.66; 95% CI: 0.55, 0.78; P < 0.001). The protection conferred was enhanced when belimumab and AMA were co-administered; the lowest flare rate was observed for the combination intravenous belimumab 1 mg/kg and AMA (18.5 cases per 1000 person-years).

CONCLUSIONS

The protection conferred from belimumab against renal flare development in patients treated for extra-renal SLE appears enhanced when belimumab was administered along with AMA. The prominent effect of low-dose belimumab warrants investigation of the efficacy of intermediate belimumab doses.

CLINICAL TRIAL IDENTIFICATION

EQ-5D full health state after therapy heralds reduced hazard to accrue subsequent organ damage in systemic lupus erythematosus

Objectives

To investigate whether self-reported EQ-5D full health state (FHS) after therapeutic intervention for active systemic lupus erythematosus (SLE) is associated with a reduced risk to accrue organ damage. In a separate analysis, we sought to investigate associations between experience of "no problems" in each one of the five dimensions of EQ-5D and the risk to accrue damage.

Methods

Data from the open-label extension periods of the BLISS-52 and BLISS-76 trials of belimumab in SLE (NCT00724867; NCT00712933) were used (N = 973). FHS was defined as an experience of "no problems" in all five EQ-5D dimensions. Organ damage was assessed annually using the Systemic Lupus International Collaborating Clinics (SLICC)/American College of Rheumatology (ACR) Damage Index (SDI). Associations between the three-level version of the EQ-5D (EQ-5D-3L) responses at open-label baseline and the first documented increase in organ damage were investigated using Cox regression accounting for age, sex, ancestry, SDI at baseline, and background therapy, and associations with SDI items were investigated using phi (φ) correlation analyses.

Results

A total of 147 patients (15.1%) accrued organ damage during follow-up, with the first increase in their SDI score occurring after a mean time of 29.1 ± 19.6 months. Lower proportions of FHS respondents accrued damage over a course of up to 7.9 years of open-label follow-up compared with no FHS respondents (p = 0.004; derived from the logrank test). FHS was associated with a reduced hazard to accrue subsequent organ damage (HR: 0.60; 95% CI: 0.38-0.96; p = 0.033) after adjustments, as was experience of "no problems" in mobility (HR: 0.61; 95% CI: 0.43-0.87; p = 0.006). "No problems" in mobility was negatively correlated with musculoskeletal damage accrual (φ = -0.08; p = 0.008) and associated with a lower hazard to accrue musculoskeletal damage in Cox regression analysis (HR: 0.38; 95% CI: 0.19-0.76; p = 0.006).

Conclusion

Experience of EQ-5D-3L FHS and "no problems" in mobility after therapeutic intervention heralded reduced hazard to accrue subsequent organ damage, especially musculoskeletal damage, suggesting that optimisation of these health-related quality of life aspects constitutes a clinically relevant treatment target in patients with SLE, along with clinical and laboratory parameters.

Persistence of Depression and Anxiety despite Short-Term Disease Activity Improvement in Patients with Systemic Lupus Erythematosus: A Single-Centre, Prospective Study

Mental disorders such as anxiety and depression are prevalent in systemic lupus erythematosus (SLE) patients, yet their association with the underlying disease activity remains uncertain and has been mostly evaluated at a cross-sectional level. To examine longitudinal trends in anxiety, depression, and lupus activity, a prospective observational study was performed on 40 adult SLE outpatients with active disease (SLE Disease Activity Index [SLEDAI]-2K ≥ 3 [excluding serology]) who received standard-of-care. Anxiety and depression were determined at baseline and 6 months by the Hospital Anxiety and Depression Scale. Treatment adherence was assessed with the Morisky Medication Adherence Scale-4. Increased anxiety (median [interquartile range] HADS-A: 11.0 [7.8]) and depression (HADS-D: 8.0 [4.8]) were found at inclusion, which remained stable and non-improving during follow-up (difference: 0.0 [4.8] and −0.5 [4.0], respectively) despite reduced SLEDAI-2K by 2.0 (4.0) (p < 0.001). Among possible baseline predictors, paid employment—but not disease activity—correlated with reduced HADS-A and HADS-D with corresponding standardized beta-coefficients of −0.35 (p = 0.017) and −0.27 (p = 0.093). Higher anxiety and depression correlated with lower treatment adherence (p = 0.041 and p = 0.088, respectively). These results indicate a high-mental disease burden in active SLE that persists despite disease control and emphasize the need to consider socioeconomic factors as part of comprehensive patient assessment.

How Can We Enhance Adherence to Medications in Patients with Systemic Lupus Erythematosus? Results from a Qualitative Study

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.

EQ-5D-3L full health state discriminates between drug and placebo in clinical trials of systemic lupus erythematosus

OBJECTIVES

The objectives of this study were to investigate the discriminative ability of EQ-5D-3L full health state (FHS) in clinical trials of SLE, and to identify factors associated with FHS after treatment.

METHODS

Data from the BLISS-52 (NCT00424476) and BLISS-76 (NCT00410384) trials of belimumab (N = 1684) were utilized. FHS was defined as a response of no problems in all five EQ-5D-3L dimensions, yielding an index score of 1. The Pearson's χ2 or Fisher's exact test was employed for comparisons, and logistic regression for adjustments and assessment of independence.

RESULTS

We demonstrated higher EQ-5D-3L FHS frequencies among patients given standard therapy (ST) plus the licensed belimumab dose vs ST alone (26.1% vs 19.4%; P = 0.001; week 52), and within SRI-4 responders vs non-responders (27.0% vs 19.8%; P < 0.001; week 52) from weeks 36 to 52. In multivariable regression analysis, SLEDAI-2K (OR: 0.90; 95% CI: 0.87, 0.94; P < 0.001) and SLICC/ACR Damage Index (OR: 0.79; 95% CI: 0.69, 0.91; P = 0.001) scores were independently associated with lower FHS frequencies at week 52, while adding monthly infusions of belimumab 10 mg/kg to ST favoured FHS perception (OR: 1.60; 95% CI: 1.15, 2.24; P = 0.006). Add-on belimumab 10 mg/kg yielded higher FHS frequencies in antimalarial users vs non-users (29.9% vs 20.1%; P = 0.011), and in anti-dsDNA- and anti-Sm- positive vs negative patients (31.4% vs 13.4%; P < 0.001 and 33.0% vs 22.6%; P = 0.010, respectively), whereas no significant differences were observed in patients given ST alone.

CONCLUSION

EQ-5D-3L FHS distinguished belimumab from placebo and responders from non-responders, and exhibited known-group validity in subgroup analysis. FHS may prove a useful patient-reported outcome in SLE studies.

Challenges of Egyptian patients with systemic lupus erythematosus during the COVID-19 pandemic

OBJECTIVES

The coronavirus disease 2019 (COVID-19) pandemic in Egypt is part of the worldwide COVID-19 pandemic that has contributed to substantial deterioration of healthcare systems. The aim of this study was to assess the challenges faced by Egyptian systemic lupus erythematosus (SLE) patients during the COVID-19 pandemic.

MATERIAL AND METHODS

This questionnaire-based study was carried out on 200 patients with SLE from Egypt. The questionnaire provided covered socioeconomic status, lupus disease data, information about COVID-19 infection, and medical and family history of COVID-19 infection.

RESULTS

The mean age of the participants was 30.1 ±8.4 years. 140/200 (70%) of the participants reported difficulty in obtaining medications during the COVID-19 pandemic, particularly antimalarials (60%). The lupus disease condition became worse because of the drug shortage in half of the participants. Wearing protective masks (74%) and using disinfectants of the hands several times per day (67%) were the most reported used measures. Forty patients (20%) had to stop or reduce taking nonsteroidal anti-inflammatory drugs while 10 patients (5%) had to start taking antimalarials as a prophylaxis against COVID-19 infection. Among those who needed hospitalization, the main cause was lupus activity, and most of them (71%) experienced difficulty in hospital admission. Thirty-two patients (16%) had confirmed COVID-19 infection. About half of them had lupus flare and had to change the medications used for treatment of lupus.

CONCLUSIONS

The current COVID-19 pandemic has a negative impact on the healthcare provided to SLE patients in Egypt. Patients with SLE faced a shortage of their medications, especially antimalarials, and difficulty in hospital admission.
