Project description:Osteonecrosis (ON) is a complex and multifactorial complication of systemic lupus erythematosus (SLE). ON is a devastating condition that causes severe pain and compromises the quality of life. The prevalence of ON in SLE patients is variable, ranging from 1.7% to 52%. However, the pathophysiology and risk factors for ON in patients with SLE have not yet been fully determined. Several mechanisms for SLE patients' propensity to develop ON have been proposed. Glucocorticoid is a widely used therapeutic option for SLE patients and high-dose glucocorticoid therapy in SLE patients is strongly associated with the development of ON. Although the hips and knees are the most commonly affected areas, it may be present at multiple anatomical locations. Clinically, ON often remains undetected until patients feel discomfort and pain at specific sites at which point the process of bone death is already advanced. However, strategies for prevention and options for treatment are limited. Here, we review the epidemiology, risk factors, diagnosis, and treatment options for glucocorticoid-induced ON, with a specific focus on patients with SLE.
Project description:ObjectivesCognitive dysfunction, and comorbidities such as mood disorder and fibromyalgia, are common in SLE. This study aims to explore the associations between fibromyalgia, mood disorders, cognitive symptoms and cognitive dysfunction in SLE patients, and their impact on quality of life.MethodsWe tested cognition in SLE patients and healthy controls, and evaluated cognitive symptoms, mood disorder, fibromyalgia, fatigue and quality of life using patient-reported outcome measures. We examined associations of these comorbidities with both patient-reported cognitive symptoms and cognitive test performance.ResultsHigh fibromyalgia symptom score and history of depression or anxiety were associated with cognitive dysfunction. There were no significant associations between current depression, anxiety symptoms or fatigue score and objective cognitive dysfunction. In contrast, mood disorder symptoms, history of mood disorder, fibromyalgia symptoms and fatigue all had significant associations with patient-reported cognitive symptoms. There were no significant associations between patient-reported cognitive symptoms and objective cognitive dysfunction. Objective cognitive dysfunction, patient-reported cognitive symptoms, history of mood disorder and fibromyalgia symptoms all had significant associations with poorer quality of life; fibromyalgia had the biggest impact.ConclusionsCognitive symptoms are common in SLE, but there were no associations between cognitive symptoms and objective cognitive dysfunction. Depression, anxiety and fibromyalgia were more consistently associated with patient-reported cognitive symptoms than with objective cognitive dysfunction. These factors all have a significant impact on quality of life. Understanding the discrepancy between patient-reported cognitive symptoms and cognitive test performance is essential to advance care in this area of unmet need.
Project description:Higher prevalence and worst outcome have been reported among people with systemic lupus erythematosus with non-European ancestries, with both genetic and socioeconomic variables as contributing factors. In Mexico, studies assessing the inequities related to quality of life for Systemic Lupus Erythematosus patients remain sparse. This study aims to assess the inequities related to quality of life in a cohort of Mexican people with SLE. This study included 942 individuals with SLE from the Mexican Lupus Registry (LupusRGMX) and two healthy control groups. Self-answered surveys were collected via the Research Electronic Data Capture platform between May 2021 and January 2023. Data was analyzed as a cross-sectional study. A random forest model was implemented to assess potential predictive variables. Permutation tests were performed to analyze the effect health providers had on diagnosis lag and quality of life's differences among socioeconomic levels. Partial correlation analysis between the number of patients and rheumatologists registered was also performed. Systemic Lupus Erythematosus participants had significantly lower quality of life than healthy people (p-values < 0.0001). Socioeconomic status, delay in diagnosis, and corticosteroid consumption were the factors that influenced QoL the most (RMSE = 9.53 with the importance variable validated); lower quality of life was associated with lower socioeconomic status (p-value < 0.0001). Disparities in health services were reflected in longer diagnosis time among people with public health providers (p-value = 0.0419). A significant association between diagnosed patients and available rheumatologists by geographical state was observed (ρ = 0.4, p-value = 0.0259), which can be translated into restricted access to specialists. Since most of our cohort exhibited low socioeconomic status, it is important to consider them as a vulnerable population; this study settles the necessity to deepen the effects of the socioeconomic disparities, allowing to design public policies and strategies aimed to reduce Systemic Lupus Erythematosus disparities, therefore improving quality of life of Mexican people with Systemic Lupus Erythematosus.
Project description: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.
Project description:BackgroundSystemic lupus erythematosus (SLE) is a chronic autoimmune disease which impacts patients' lives. Many studies in high-income countries have focused on their health-related quality of life (HRQoL). However, evidence of awareness of SLE and HRQoL in low- and middle-income countries is lacking. Therefore, this study aimed to identify the determinants of HRQoL of SLE patients in Vietnam, a lower-middle income country.MethodsThis cross-sectional study was conducted at the National Hospital of Dermatology and Venereology in 2019. A pre-tested structured questionnaire was used to collect data. It consisted of Short Form-36 to assess HRQoL which comprised physical and mental component summaries, Multidimensional Scale of Perceived Social Support, Satisfaction with Life Scale, and Mental Adjustment to SLE. Multiple linear regression was used to identify the determinants of HRQoL.ResultsOne hundred thirty four patients with SLE participated in this study. The majority of the patients were women (n = 126, 94.0%). The mean age of all participants was 37.9 years old (standard deviation [SD] 12.5). Of 134 participants, 104 (77.6%) were married. Older patients were more likely to have a lower score of mental component summary (B=-0.45, 95% CI -0.73, -0.17). Patients with more children were more likely to have a lower score of physical component summary (B=-5.14, 95% CI -9.27, -1.00). Patients who felt more helplessness or hopelessness were more likely to have lower scores of physical and mental component summaries (B=-1.85, 95% CI -2.80, -0.90; B=-1.69, 95% CI -2.57, -0.81). Also, patients who felt more anxious were more likely to have a lower score of mental component summary (B=-1.04, 95% CI -1.77, -0.32). Patients who were more satisfied with their lives were more likely to have higher scores of physical and mental component summaries (B = 1.07, 95% CI 0.50, 1.64; B = 1.08, 95% CI 0.55, 1.61).ConclusionFactors associated with lower HRQoL in Vietnam were feelings of helplessness or hopelessness, and burdens of parenting roles. However, social support can contribute to a higher HRQoL, such as information support, self-support groups, and daycare services provided at the community level.
Project description:Systemic lupus erythematosus (SLE) is a highly heterogeneous autoimmune disease that primarily affects women. Currently, in the search for the mechanisms of SLE pathogenesis, the association of lifestyle factors such as diet, cigarette smoking, ultraviolet radiation exposure, alcohol and caffeine-rich beverage consumption with SLE susceptibility has been systematically investigated. The cellular and molecular mechanisms mediating lifestyle effects on SLE occurrence, including interactions between genetic risk loci and environment, epigenetic changes, immune dysfunction, hyper-inflammatory response, and cytotoxicity, have been proposed. In the present review of the reports published in reputable peer-reviewed journals and government websites, we consider the current knowledge about the relationships between lifestyle factors and SLE incidence and outline directions of future research in this area. Formulation of practical measures with regard to the lifestyle in the future will benefit SLE patients and may provide potential therapy strategies.
Project description:ObjectiveGlucocorticoid (GC) tapering and withdrawal to reduce damage represents a key aspect of the European Alliance of Associations for Rheumatology (EULAR) SLE recommendations. However, optimal strategies for relapse-free GC cessation remain ill-defined. We characterised clinical predictors and their combined effect on flares in patients with SLE who discontinued GC.MethodsRetrospective cohort of 324 patients with active SLE (PGA ≥1.5 and/or SLEDAI-2K ≥6) who received GC as part of treatment intensification (median follow-up 60 months). Survival and generalised linear models estimated SELENA-SLEDAI flare risks and their predictors.ResultsGCs were discontinued in 220 (67.9%) patients with 1-year risks for overall and severe flares of 50% and 25%, respectively (HR: 1.48; 95% CI: 1.12 to 1.96 for overall flares; HR: 1.52; 95% CI: 1.03 to 2.25 for severe flares, compared with non-withdrawers). Flare risk was lowered when GCs were ceased during remission (DORIS) or Lupus Low Disease Activity State (LLDAS; excluding remission) (HR for severe flares: 0.23; 0.12 to 0.43 and 0.30; 0.18 to 0.50, respectively), with each additional month in targets providing further protection. Hydroxychloroquine prevented total (HR: 0.37; 0.26 to 0.53) and severe flares (HR: 0.33; 0.21 to 0.52), while mycophenolate and azathioprine reduced overall flares. Prednisone tapering from 7.5 mg/day to 0 over >6 months improved severe flare-free outcome (HR: 0.57; 0.37 to 0.90). Random survival forests identified DORIS/LLDAS, hydroxychloroquine use and slow GC tapering as top predictors, whose coexistence reduced overall and severe flares by ~25 fold and ~50 fold, respectively. This combination reduced damage (IRR: 0.31; 0.08 to 0.84) without inducing flares (IRR: 0.52; 95% CI: 0.18 to 1.16) compared with GC non-withdrawers.ConclusionLow or absent disease activity, slow tapering and hydroxychloroquine use minimise the risk of flares, facilitating GC discontinuation-a major goal in SLE.
Project description:ObjectivesPatients with systemic lupus erythematosus (SLE) are usually treated with glucocorticosteroids even during periods of clinically quiescent disease. A recent study showed that abrupt glucocorticoid withdrawal was associated with an increased likelihood of flare in the next 12 months. The aim of the present study was to assess clinical flare rates and damage accrual in patients who tapered glucocorticosteroids gradually.MethodsPatients from the Toronto Lupus Clinic with 2 consecutive years of clinically quiescent disease were retrieved from the database. Individuals who maintained a low prednisone dose (5 mg/day) comprised the maintenance group, whereas patients who gradually tapered prednisone within these two years comprised the withdrawal group. All individuals were followed for 2 years after prednisone discontinuation or the corresponding date for the maintenance group. Propensity score matching was implemented to adjust for certain baseline differences. Outcomes included clinical flares and damage accrual.ResultsOf 270 eligible patients, 204 were matched (102 in each group). Flare rate (any increase in clinical SLE Disease Activity Index 2000) was lower in the withdrawal group both at 12 (17.6% versus 29.4%; P = 0.023) and 24 months (33.3% versus 50%; P = 0.01). Moderate to severe flares (requiring systemic treatment escalation) were not different at 12 months (10.8% versus 13.7%; P = 0.467) but were less frequent at 24 months (14.7% versus 27.5%; P = 0.024). Damage accrual was less frequent in the withdrawal group (6.9% versus 17.6%; P = 0.022). No predictors for clinical flares were identified.ConclusionGradual glucocorticoid withdrawal is safe in clinically quiescent SLE and is associated with fewer clinical flares and less damage accrual at 24 months.
Project description:Systemic lupus erythematosus (SLE) reduces the health-related quality of life (HRQoL), even during periods of disease quiescence. We investigated whether subclinical inflammation as reflected by cytokine levels is linked with reduced HRQoL. A cross-sectional study of SLE patients (n = 52, mean age 47.3, 86.5% female) who completed a Short Form Health Survey-36 (SF-36) questionnaire. The clinical and demographic data, scores for the disease activity (SLEDAI-2K), organ damage (SDI), and laboratory data were collected simultaneously. The autoantibody and cytokine levels (IFN-γ, IL-1β, IL-4, IL-6, IL-10, IL-12, IL-17, BAFF, TNF-α, TGF-β1, MIP-1α, MIP-1β and MCP-1 (levels in pg/mL) were quantified by sandwich ELISA. The comparisons and associations were assessed non-parametrically, and a multiple regression determined the effect sizes (ES) of the variables on the SF-36 domain and summary scores. The SF-36 summary and domain scores for SLE patients were significantly (20-40%) lower than in a comparable control group, with the exception of the Mental Health scores (p = 0.06). SLE patients had a normal body mass index (BMI) (median, 24.2 kg/m2), a high rate of smoking (69.2%), and usage of social security benefits (90.4%). TGF-β1 (ES 0.06), IL-12 (ES -0.11), IFN-γ (ES 0.07) and MCP-1 (ES 0.06) influenced the SF-36 domain scores; and MCP-1 (ES 0.04) influenced the Mental Health Summary Score (MCS). Obvious manifestations, including patient visual analogue scale (VAS) (ES -2.84 to -6.29), alopecia (ES -14.89), malar rash (ES -14.26), and analgesic requirement (ES -19.38), independently influenced the SF-36 items; however, the SF-36 scores were not reflected by the physician VAS or disease activity (SLEDAI-2K). Cytokines had a minimal impact on HRQoL in SLE patients, especially compared to visible skin manifestations, central nervous system (CNS) damage, and pain. Better tools are needed to capture HRQoL in measures of disease activity.
Project description:IntroductionThe purpose of this research is to assess the effects of oral ibandronate on bone microarchitecture by using high-resolution peripheral quantitative computed tomography (HR-pQCT) in patients with systemic lupus erythematosus (SLE) taking a long-term glucocorticoid.MethodsIn this double-blind placebo-controlled study, 40 Chinese female SLE patients taking prednisolone were randomly assigned to receive either monthly oral ibandronate (150 mg) or placebo with daily 1-hydroxycholecalciferol (Alfacalcidol; 1 μg) and calcium supplement for 12 months. Assessments of bone microarchitecture by using HR-pQCT and area bone mineral density (aBMD) of the lumbar spine and hip with dual-energy x-ray absorptiometry (DXA) were performed at baseline and 12 months.ResultsNo differences in baseline characteristics were found between the two groups. After 12 months, no statistical differences were noted in any of the bone densities, microarchitectural parameters, or percentage changes of these parameters, as measured with HR-pQCT or DXA between the two groups. However, within the active group, the percentage improvement was significant in cortical bone density (P = 0.023) which was absent in the placebo group. Improvement was also seen in the aBMD of both the lumbar spine (P < 0.0001) and the hip (P < 0.005). In the placebo group, the percentage increase in trabecular separation was significant (P = 0.04), and the percentage improvement in aBMD in the spine also was significant (P = 0.049).ConclusionsOral ibandronate treatment improves microarchitecture in SLE patients taking long-term glucocorticoid assessed with HR-pQCT, and this new technology may have a role in assessing bony changes in future longitudinal studies in SLE patients.Trial registrationClinicalTrials.gov identifier: NCT00668330.
