Outcome Of Systemic Lupus Erythematosus Research Articles

Cytomegalovirus infection and disease in systemic lupus erythematosus patients at a high-complexity hospital in southwestern Colombia.

Cytomegalovirus (CMV) infection and disease is a condition usually described in immunocompromised patients, but among them, those with connective tissue diseases are poorly represented. Here we present the clinical, laboratory characteristics, management and outcomes of systemic lupus erythematosus (SLE) patients who presented with a CMV infection/disease to a high complexity hospital in southwestern Colombia between 2011 and 2020. 16 SLE patients were found to have a CMV infection. SLE was predominantly characterized by renal involvement (10 patients; 62.50%), and 14 patients (87.5%) were receiving steroids previous to the CMV infection. The entire sample required hospital admission, mainly related to acute kidney injury, and nine patients were admitted to the intensive care unit (ICU). Gastrointestinal organ damage was the most common CMV disease manifestation. All patients received ganciclovir, five of them (31.25%) suffered from septic shock, and seven (43.75%) died. Age ≥38years and the presence of septic shock at admission were correlated to the mortality outcome. To our knowledge, this is the first publication evaluating SLE patients with CMV infection/disease in a Colombian population.

Relationship of serum and dietary vitamin D with high cardiometabolic risk in Mexican systemic lupus erythematosus patients: A cross-sectional study.

Objetive: Serum and dietary vitamin D could influence clinical disease activity and cardiometabolic outcomes in systemic lupus erythematosus (SLE). This study aimed to assess the relationship of serum and dietary vitamin D with cardiometabolic risk in Mexican SLE patients and healthy subjects (HS).Methods: 224 SLE patients and 201 HS were included in this cross-sectional study. Serum calcidiol was measured using a competitive enzyme-linked immunosorbent assay (ELISA). Vitamin D dietary intake was assessed by collecting three 24h food records. Dietary patterns (DPs) were identified using principal component analysis (PCA). Cardiometabolic status was analyzed through biochemical measurements and cardiometabolic indexes.Results: Calcidiol deficiency (<20 ng/mL) was associated with 1.66-fold higher risk of excess weight by body mass index (BMI) (≥25 kg/m2) (p = .02), 2.25-fold higher risk to low high-density lipoprotein-cholesterol (HDL-C) (<40 mg/dL) (p < .001), and 1.74-fold higher risk to high triglycerides (TG) ≥150 mg/dL (p = .02). Inadequate vitamin D dietary intake was associated with 1.92-fold higher risk of presenting non-healthy waist circumference (WC) (>80 cm) (p < .01), 2.05-fold higher risk of android waist to hip ratio (WHR ≥85) (p < .01), and 1.72-fold higher risk to excess weight (p = .02). Non-adherence to a DP rich in vitamin D food sources was associated with higher WC, WHR, triglycerides, and lower high-density lipoprotein-cholesterol (HDL-C); furthermore, in HS, non-adherence to the DP rich in vitamin D food sources provided 2.11-fold higher risk to calcidiol deficiency.In Cconclusion: A pattern of Calcidiol deficiency, inadequate vitamin D dietary intake, and non-adherence to a DP rich in vitamin D food sources was related to high cardiometabolic risk in SLE patients and HS.

Mental health conditions in patients with systemic lupus erythematosus: A systematic review and meta-analysis.

The reported prevalence of mental health conditions (MHCs) in people with systemic lupus erythematosus (SLE) ranges widely. Whether MHCs are associated with increased risk of SLE or the outcomes of the disease is unclear. This paper aimed to conduct an umbrella and updated meta-analysis of MHCs in people with SLE and to identify whether MHCs are associated with the risk of SLE or patient outcomes. We comprehensively searched PubMed, Web of Science, and Embase databases to identify relevant studies published before June 2023. Random-effect models were used to calculate the pooled prevalence and risk ratios for each MHC. 203 studies with 1485094 individuals were included. The most MHCs observed in patients with SLE were sleep disturbance (59.7% [95% CI, 52.4%-66.8%]) among adults and cognitive dysfunction (63.4% [95% CI, 46.9%-77.9%]) among children. We found that depressive disorders (RR = 2.30, 95% CI = 1.94-2.75) and posttraumatic stress disorder (RR = 1.93, 95% CI = 1.61-2.31) in the general population were significantly associated with an increased likelihood of developing SLE. Furthermore, concurrent MHCs were linked to unfavorable outcomes in patients with SLE, such as decreased quality of life, increased risk of unemployment, and other somatic comorbidities. Our study demonstrated a high prevalence of MHCs among patients with SLE. Individuals with pre-existing mental disorders exhibited an elevated susceptibility to developing SLE, and patients presenting with MHCs were at increased risk of experiencing suboptimal health and functional outcomes. Therefore, evaluating and preventing MHCs should be considered as an integral component of the comprehensive treatment strategy for SLE.

Comparing pregnancy outcomes in patients with Systemic Lupus Erythematosus (SLE) and Undifferentiated Connective Tissue Disease (UCTD): a descriptive cohort study

BackgroundFemales diagnosed with systemic lupus erythematosus (SLE) face an elevated risk of adverse pregnancy outcomes (APOs). However, the evidence regarding whether a similar association exists in patients with undifferentiated connective tissue disease (UCTD) is inconclusive. MethodsWe conducted a retrospective review (2006–2019) of pregnancy outcomes among patients with SLE (n = 51) and UCTD (n = 20) within our institution. We examined the occurrence of various APOs, encompassing miscarriage, stillbirth, termination, preterm birth, pre-eclampsia, eclampsia, HELLP syndrome, intrauterine growth restriction, abruption placentae, congenital heart block, or other cardiac abnormalities. ResultsThe mean age at pregnancy was 35 ± 7.0 years for patients with SLE and 35 ± 6.8 years for those with UCTD (p = 0.349). The proportion of Caucasian women was 47% in SLE and 80% in UCTD. Pregnancies in both groups were planned (81% in SLE and 77% in UCTD), and patients presented with inactive disease at conception (96% in SLE and 89% in UCTD). Hydroxychloroquine at conception was utilized by 86% of women with SLE, in contrast to 36% in the UCTD group. Both, SLE and UCTD cohorts exhibited low rates of disease flares during pregnancy and/or puerperium (14% vs. 10%). The incidence of APOs was 15.6% in SLE patients compared to 5% in those with UCTD (Risk difference 19.5%; 95% confidence interval: −3.9 to 43.1; p = 0.4237). ConclusionOur study underscores the importance of strategic pregnancy planning and the maintenance of appropriate treatment throughout pregnancy to ensure optimal disease management and minimize adverse outcomes in both SLE and UCTD pregnancies.

Racial and Ethnic Composition of Populations Served by Freestanding Children's Hospitals and Disparities in Outcomes of Pediatric Lupus.

Health disparities may be driven by hospital-level factors. We assessed whether racial and ethnic composition of populations hospitals serve explain or modify disparities in hospital outcomes of children with systemic lupus erythematosus (SLE). In this retrospective cohort study of patients 5 to 26 years old with SLE at 47 children's hospitals in the Pediatric Health Information System (2006-2021), race and ethnicity were assessed at the patient level and hospital level (proportion of total admissions composed of Black or Hispanic patients, respectively). Outcomes included intensive care unit (ICU) admission or adverse renal outcome (end-stage renal disease, dialysis, or transplant) during follow-up. We estimated racial and ethnic disparities, adjusted or stratified by hospital racial or ethnic composition. Of 8,125 patients with SLE, 2,293 (28%) required ICU admission, and 698 (9%) had an adverse renal outcome. Black and non-Hispanic White disparities in ICU admission were observed only at hospitals serving higher proportions of Black patients (odds ratio [OR] 1.29, 95% confidence interval [95% CI] 1.04-1.59 vs OR 1.07, 95% CI 0.83-1.38). Larger Black and non-Hispanic White disparities in adverse renal outcomes were observed at hospitals with higher Black racial composition (OR 2.0, 95% CI 1.4-2.8 vs OR 1.7, 95% CI 1.1-2.4). Conversely, Hispanic versus non-Hispanic disparities in renal outcomes persisted after adjustment for hospital-reported Hispanic ethnic composition but were observed only at hospitals with lower proportions of Hispanic patients. Worse Black and White disparities in SLE outcomes are observed at children's hospitals serving more Black children, whereas distinct patterns are observed for Hispanic and non-Hispanic disparities. Reporting of hospital characteristics related to populations served is needed to identify modifiable drivers of hospital-level variation.

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.

Lupus nephritis and socioeconomic status: Findings from the Southern California lupus registry.

Lupus nephritis (LN) is a major cause of morbidity and mortality in systemic lupus erythematosus (SLE). Despite multiple studies addressing healthcare disparities, disparate outcomes in LN persist. We investigate herein the association between socioeconomic status (SES) and LN as well as the association between SES, SLE disease activity index (SLEDAI), and treatment response. Patients were selected from the Southern California Lupus Registry (SCOLR), a registry enrolling all-comers with SLE. Analysis was completed on individuals with public vs. private insurance. Insurance and ethnicity were used as surrogate variables for SES, and we tested differences in means. After adjusting for age and sex, public insurance was independently associated with the prevalence of LN. Analysis of 35 patients revealed greater proteinuria and mean SLEDAI in patients with public insurance at baseline and 6 months. Baseline, 6-, and 12-month SLEDAI means were significantly lower in Asian/Pacific Islanders (PI) compared to others. While non-Hispanic Whites demonstrated mean SLEDAI improvement over 6 months, Asians/PI, Blacks, and Hispanics demonstrated worsened disease activity on average. Low SES, when defined by insurance, is associated with greater adverse outcomes in SLE. This is the first regional study that compares differences in treatment response in LN patients with low SES as well as association of SES with long-term outcomes in SLE and LN in southern California.

Systemic lupus erythematosus is associated with increased risk of mortality and acute kidney injury in patients with COVID-19 hospitalization: Insights from a National Inpatient Sample analysis.

The COVID-19 pandemic has significantly impacted global health, especially for patients with chronic diseases that may compromise the immune system. This study investigates the association between systemic lupus erythematosus (SLE) and COVID-19 outcomes. Data from the National Inpatient Sample (NIS) were analyzed to create a retrospective cohort of COVID-19 hospitalizations, comparing patients with and without SLE. Propensity-score matched analysis was conducted to assess the association between SLE and clinical outcomes in COVID-19 hospitalizations. The study included over a million COVID-19 hospitalizations, with approximately 0.5% having a secondary diagnosis of SLE. The SLE-COVID hospitalizations were predominantly female and younger, with a median age of 57.2, while the non-SLE-COVID group had a median age of 64.8 years. Comorbidities such as chronic obstructive pulmonary disease, renal failure, liver disease, and others were more prevalent in the SLE-COVID group. Patients with SLE and COVID-19 had a significantly higher incidence of acute kidney injury requiring dialysis than those without SLE. In-hospital mortality was higher in the SLE group, particularly in the 18-44 year age group (6.15% vs 2.47%, p = .022). COVID-19 patients with SLE are at an increased mortality risk, especially in the younger age group, and a higher incidence of acute kidney injury requiring dialysis. The elevated risk of adverse outcomes underscores the vulnerability of SLE patients to COVID-19. These findings emphasize the importance of special precautions and patient education for individuals with SLE to mitigate the risks associated with COVID-19.

Evaluation of core decompression outcome in systemic lupus erythematosus with hip osteonecrosis: a retrospective cohort study

BackgroundOsteonecrosis is a major cause of morbidity for patients with systemic lupus erythematosus (SLE). Although core decompression is an approved and trusted technique to prevent further joint deterioration, this surgical method seems to be less beneficial for SLE patients. We aimed to evaluate the outcomes of core decompression in SLE patients with primary stages of femoral head osteonecrosis.MethodsIn this study, 23 patients (39 affected hip joints) with osteonecrosis of the femoral head with stage II of the disease, based on the Ficat-Arlet classification system, underwent core decompression. Also, patients demographic characteristics, clinical data, medication history, comorbidities, immunological findings, hip plain radiographs, history of total hip arthroplasty after core decompression, and patients satisfaction with joint function according to the Oxford hip score questionnaire were obtained.ResultsIn the study, 53.8% of affected joints showed signs of radiographic deterioration in follow-up imaging. Sixty-one and a half percent (61.5%) of patients had unsatisfactory joint performance. A third (33.3%) of affected hip joints underwent total hip arthroplasty up to 5 years from core decompression. SLE patients with a history of receiving bisphosphonate were 83.2% less dissatisfied with their joint function than patients without a history of bisphosphonate use (P < 0.02). Of the 23 studied cases, the mean cumulative dose of prednisolone before and after core decompression surgery was 46.41 mg and 14.74 mg respectively. Besides, one case (2.6%) that had a high anti-phospholipid antibodies level during follow-up did not have any radiographic deterioration, and 9 cases (23.1%) had some degrees of radiographic deterioration.ConclusionsThe patients group that used bis-phosphonate, had a higher level of satisfaction with joint function after core decompression. Patients with high-level anti-phospholipid antibodies are related to a poor prognosis after core decompression.

Economic insecurities and patient-reported outcomes in patients with systemic lupus erythematosus in the USA: a cross-sectional analysis of data from the California Lupus Epidemiology Study

Social determinants of health are consistently associated with systemic lupus erythematosus (SLE) outcomes. However, social determinants of health are typically measured with conventional socioeconomic status factors such as income or education. We assessed the association of economic insecurities (ie, food, housing, health care, and financial insecurity) with patient-reported outcomes in a cohort of patients with SLE. In this cross-sectional analysis, data were derived from the California Lupus Epidemiology Study based in the San Francisco Bay Area, CA, USA. Participants were recruited between Feb 25, 2015, and Jan 10, 2018, from rheumatology clinics. Inclusion criteria were Bay Area residency; oral fluency in English, Spanish, Cantonese, or Mandarin; 18 years or older; ability to provide informed consent; and a physician confirmed SLE diagnosis. Food, housing, health care, and financial economic insecurities were assessed by validated screening tools. Patient-reported outcomes were obtained using PROMIS, Quality of Life in Neurological Disorders (known as Neuro-QoL) Cognitive Function short form, Patient Health Questionnaire (PHQ)-8, and General Anxiety Disorder (GAD)-7 instruments. Poverty was defined as household income of 125% or less of the federal poverty limit. Lower education was defined as less than college-graduate education. The association of economic insecurities with patient-reported outcomes was assessed by multivariable linear regression models adjusting for demographics, SLE disease characteristics, and comorbidities. We tested for interactions of insecurities with poverty and education. The final cohort included 252 participants. Mean age was 49·7 (SD 13·4) years, 228 (90%) of 252 were women and 24 (10%) were men. 80 (32%) individuals self-identified as Asian, 26 (10%) as Black, 101 (40%) as White, eight (3%) as mixed race, and 37 (15%) as other race; 59 (23%) self-identified as Hispanic. 135 (54%) individuals had at least one insecurity. Insecurities were highly prevalent, and more common in those with poverty and lower education. Adjusted multivariate analyses revealed that participants with any insecurity had significantly worse scores across all measured patient-reported outcomes. For physical function, no insecurity had an adjusted mean score of 48·9 (95% CI 47·5-50·3) and any insecurity had 45·7 (44·3-47·0; p=0·0017). For pain interference, no insecurity was 52·0 (50·5-53·5) and any insecurity was 54·4 (53·0-55·8; p=0·031). For fatigue, no insecurity was 50·5 (48·8-52·3) and any insecurity was 54·9 (53·3-56·5; p=0·0005). For sleep disturbance, no insecurity was 49·9 (48·3-51·6) and any insecurity was 52·9 (51·4-54·5; p=0·012). For cognitive function, no insecurity was 49·3 (47·7-50·9) and any insecurity was 45·6 (44·1-47·0; p=0·0011). For PHQ-8, no insecurity was 4·4 (3·6-5·1) and any insecurity was 6·1 (5·4-6·8; p=0·0013). For GAD-7, no insecurity was 3·3 (2·6-4·1) and any insecurity was 5·2 (4·5-5·9; p=0·0008). Individuals with more insecurities had worse patient-reported outcomes. There were no statistically significant interactions between insecurities and poverty or education. Having any economic insecurity was associated with worse outcomes for people with SLE regardless of poverty or education. The findings of this study provide insight into the relationship between economic insecurities and SLE outcomes and underscore the need to assess whether interventions that directly address these insecurities can reduce health disparities in SLE.

Mendelian randomization reveals systemic lupus erythematosus and rheumatoid arthritis and risk of adverse pregnancy outcomes

BackgroundThe effect of systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) on adverse pregnancy outcomes is a controversial topic. This study aimed to use Mendelian randomization (MR) analysis to assess the causal relationship between SLE, RA and adverse pregnancy outcomes. MethodsGenetic variants for SLE and RA, as well as adverse pregnancy outcomes, were derived from pooled statistics from large public genome-wide association studies. Several methods, such as inverse variance weighting (IVW), MR-Egger, weighted median and MR-Pleiotropic Residuals Sum and Outliers, were employed to estimate two-sample causality. ResultsGenetic prediction of SLE was associated with higher odds of preterm labour [odds ratio (OR) 1.03, 95 % confidence interval (CI) 1.01–1.05; p = 0.008]. RA was associated with higher odds of preterm labour (OR 1.03, 95 % CI 1.01–1.06; p = 0.009), pre-eclampsia or eclampsia (OR 1.04, 95 % CI 1.01–1.07; p = 0.005), and poor fetal growth (OR 1.08, 95 % CI 1.04–1.12; p = 2.91 × 10−5). The results of bidirectional MR analysis did not indicate that SLE was associated with spontaneous abortion, pre-eclampsia or eclampsia, preterm rupture of membranes, or poor fetal growth (p-value for IVW 0.13–0.97). ConclusionsThis study found a genetic association between SLE and the risk of preterm labour, and highlights the importance of perinatal care and monitoring for patients with SLE. Furthermore, RA was found to be associated with a wide range of adverse outcomes, including preterm labour, pre-eclampsia or eclampsia, and poor fetal growth; as such, there is a need for more intensive therapeutic interventions and prenatal monitoring.

Worse cardiovascular and renal outcome in male SLE patients

Systemic lupus erythematosus (SLE) in males is rare and poorly understood. Thus, still little is known about sex differences in SLE. We set out to identify sex differences regarding clinical manifestations as well as renal and cardiovascular outcomes of SLE. We analyzed patient data from the Swiss SLE Cohort Study. Cumulative clinical manifestations according to the updated American College of Rheumatology criteria were recorded at inclusion. Cardiovascular events were recorded within Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SLICC-SDI). Renal failure was defined as eGFR < 15 ml/min/1.73 m2, initiation of renal replacement therapy or doubling of serum creatinine which were all assessed yearly or documented as end stage renal disease in SLICC-SDI. Risk differences were calculated using logistic regression and cox regression models. We analyzed 93 men and 529 women with a median follow up time of 2 years. Males were significantly older at diagnosis (44.4 versus 33.1 years, p < 0.001) and had less often arthritis (57% versus 74%, p = 0.001) and dermatological disorders (61% versus 76%, p < 0.01). In multivariate analysis female sex remained a significantly associated with arthritis and dermatological disorders. In multivariate analysis men had a significantly higher hazard ratio of 2.3 for renal failure (95% confidence interval (95%-CI) 1.1–5.2, p < 0.04). Total SLICC-SDI Score was comparable. Men had significantly more coronary artery disease (CAD) (17% versus 4%, p < 0.001) and myocardial infarction (10% versus 2%, p < 0.01). In multivariate analysis, male sex remained a significant risk factor for CAD (odds ratio (OR) 5.6, 95%-CI 2.3–13.7, p < 0.001) and myocardial infarction (OR 8.3, 95%-CI 2.1–32.6, p = 0.002). This first sex study in a western European population demonstrates significant sex differences in SLE. Male sex is a risk factor for cardiovascular events and renal failure in SLE. Potential etiological pathomechanisms such as hormonal or X-chromosomal factors remain to be further investigated.

Safety and efficacy of biological agents in the treatment of Systemic Lupus Erythematosus (SLE)

BackgroundTo determine the safety and efficacy of biological agents used in the treatment of systemic lupus erythematosus (SLE) in adults.MethodsSystematic review and meta-analysis following PRISMA guidelines.Data sourcesMEDLINE (through Pubmed), EMBASE, Cochrane library, Clinicaltrials.gov, Australianclinicaltrials.gov.au, ANZCTR.org.au and WHO International Clinical Trials Registry Platform for studies published from 20 May 2021 and 15 years prior. A grey literature search was performed and completed on 31 May 2021.Study criteriaPhase II, III or quasi randomised controlled trials, studies with only cerebral or cutaneous lupus were excluded. Data extraction: Two authors independently screened studies for eligibility, extracted, reviewed data for accuracy, and used the Cochrane tool to assess risk of bias.ResultsForty-four studies were identified, consisting of 15 groups of drugs and 25 different biological agents, totalling 16,889 patients. The main outcomes assessed included Systemic Lupus Erythematosus Responder Index (SRI), BILAG-Based Composite Lupus Assessment (BICLA) and combined combined/partial renal remission (CRR/PRR).Four groups of biologics were found to improve outcomes. Anti-interferons: Anifrolumab increased BICLA response and SRI 5 to 8, decreased prednisone dosages, with increased herpes zoster infections, but fewer serious adverse events. Sifalimumab improved SRI but also increased herpes zoster infections. Anti BAFF/BLyS and/or APRIL: Belimumab consistently improved SRI 4, decreased prednisone dosages, increased combined CRR/PRR, and had no adverse safety outcomes. Tabalumab increased SRI 5 at 52 weeks with no steroid sparing effect but was associated with increased infusion related adverse events. Telitacicept improved SRI 4 at 52 weeks, with no increased adverse events, though data was rather sparse. Anti CD-20 monoclonal antibody, Obinutuzumab increased combined CRR/PRR at 1 and 2 years. Anti IL12/23 monoclonal antibody, Ustekinumab, increased SRI 4 to 6, but not BICLA at 24 weeks, with no concerning safety outcomes.ConclusionMultiple biologic agents are shown in high quality studies to have a significant therapeutic impact on outcomes in SLE.

Outcomes of hemorrhagic stroke in patients with autoimmune rheumatic diseases: An analysis of the US Nationwide Inpatient Sample.

To determine whether and how rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and systemic sclerosis (SSc) affect outcomes in patients admitted for hemorrhagic stroke. This study screened the Nationwide Inpatient Sample database for adults aged ≥20 years admitted to US hospitals with a principal diagnosis of intracerebral hemorrhage (ICH) between 2005 and 2018. Diagnoses were determined using the International Classification of Diseases, 9th and 10th revisions (ICD-9 and ICD-10) diagnostic codes for ICH (ICD-9: 431, 432; ICD-10: I61, I62). Study outcomes were: (1) in-hospital mortality; (2) unfavorable discharge, defined as transfer to nursing homes or long-term care facilities; and (3) prolonged length of stay (LOS), defined as LOS >75th centile. Associations between comorbid RA, SLE, and SSc and clinical outcomes show a significantly lower risk of in-hospital mortality and prolonged LOS in RA patients. After admissions for ICH, the risk for in-hospital mortality and prolonged LOS was decreased in RA patients, and the risk for unfavorable discharge (long-term care) was reduced in SLE patients. Among patients admitted to US hospitals for hemorrhagic stroke, patients with RA had decreased risk for in-hospital mortality and prolonged LOS.

Mortality and causes of death in systemic lupus erythematosus in New Zealand: A population-based study.

This study aims to assess the mortality of systemic lupus erythematosus (SLE) patients and examine whether there are variations by subgroup. SLE patients from 2005-2021 were identified from the national administrative datasets. The underlying causes of death were examined. Standardised mortality ratio (SMR) was estimated to compare the relative rate of observed deaths in SLE patients to expected deaths in the general population. The hazard ratios (HR) and 95% confidence intervals (CI) of all-cause mortality and SLE specific mortality by ethnicity were estimated after adjustment for age using a Cox proportional hazards model. Of the 2,802 patients included for analysis, 699 (24.9%) died with 209 (29.9%) SLE deaths. The age-standardised mortality rate of SLE was 0.29 per 100 000 for women and 0.05 for men. The mean age at death was 65.3 ± 17.1 years. Younger patients were more likely to have SLE as the underlying cause of death, from 78.9% for those under 20 years old to 18.7% for those aged 70-79 years. Compared with the general population, SLE patients were four times more likely to die (SMR: 4.0; 95% CI: 3.7-4.3). Young patients had higher SMRs than older patients. Māori had worse all-cause mortality (HR: 1.72; 95% CI: 1.10-2.67) and SLE specific mortality (HR: 2.60; 95% CI: 1.29-5.24) than others. The outcomes of SLE in New Zealand were still very poor compared with the general population. Māori with SLE had worse survival than others. Further research is needed to identify the reasons to this disparity.

Potential of bone morphogenetic protein-7 in treatment of lupus nephritis: addressing the hurdles to implementation.

Up to 50% of systemic lupus erythematosus (SLE) patients world-wide develop lupus nephritis (LN). In low to middle income countries and in particular in sub-Saharan Africa, where SLE is prevalent with a more aggressive course, LN and end stage renal disease is a major cause of mortality. While developed countries have the funding to invest in SLE and LN research, patients of African descent are often underrepresented in clinical trials. Thus, the complex influence of ethnicity and genetic background on outcome of LN and SLE as a whole, is not fully understood. Several pathophysiological mechanisms including major role players driving LN have been identified. A large body of literature suggest that prevention of fibrosis-which contributes to chronicity of LN-may significantly improve long-term prognosis. Bone morphogenetic protein-7 (BMP-7) was first identified as a therapeutic option in this context decades ago and evidence of its benefit in various conditions, including LN, is ever-increasing. Despite these facts, BMP-7 is not being implemented as therapy in the context of renal disease. With this review, we briefly summarise current understanding of LN pathology and discuss the evidence in support of therapeutic potential of BMP-7 in this context. Lastly, we address the obstacles that need to be overcome, before BMP-7 may become available as LN treatment.

Disparities in Lupus and the Role of Social Determinants of Health: Current State of Knowledge and Directions for Future Research.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease. The complex relationships between race and ethnicity and social determinants of health (SDOH) in influencing SLE and its course are increasingly appreciated. Multiple SDOH have been strongly associated with lupus incidence and outcomes and contribute to health disparities in lupus. Measures of socioeconomic status, including economic instability, poverty, unemployment, and food insecurity, as well as features of the neighborhood and built environment, including lack of safe and affordable housing, crime, stress, racial segregation, and discrimination, are associated with race and ethnicity in the US and are risk factors for poor outcomes in lupus. In this scientific statement, we aimed to summarize current evidence on the role of SDOH in relation to racial and ethnic disparities in SLE and SLE outcomes, primarily as experienced in the U.S. Lupus Foundation of America's Health Disparities Advisory Panel, comprising 10 health disparity experts, including academic researchers and patients, who met 12 times over the course of 18 months in assembling and reviewing the data for this study. Sources included articles published from 2011 to 2023 in PubMed, Centers for Disease Control and Prevention data, and bibliographies and recommendations. Search terms included lupus, race, ethnicity, and SDOH domains. Data were extracted and synthesized into this scientific statement. Poorer neighborhoods correlate with increased damage, reduced care, and stress-induced lupus flares. Large disparities in health care affordability, accessibility, and acceptability exist in the US, varying by region, insurance status, and racial and minority groups. Preliminary interventions targeted social support, depression, and shared-decision-making, but more research and intervention implementation and evaluation are needed. Disparities in lupus across racial and ethnic groups in the US are driven by SDOH, some of which are more easily remediable than others. A multidimensional and multidisciplinary approach involving various stakeholder groups is needed to address these complex challenges, address these diminish disparities, and improve outcomes.

SLICC-Frailty Index and Its Association with Low Bone Mineral Density and Vertebral Fractures in Women with Systemic Lupus Erythematosus.

The Systemic Lupus International Clinics (SLICC)-Frailty Index (FI) is associated with adverse outcomes in systemic lupus erythematosus (SLE). However, to our knowledge, its association with bone mineral density (BMD) and vertebral fractures (VF), has not been investigated using a standardized methods. Our aim was to evaluate the relationship between frailty assessed by SLICC-FI, and BMD and VF in Mestizo women with SLE. Adult women were included in this cross-sectional study. Information concerning the risk factors for VF and BMD in the lumbar spine and total hip was acquired. SLICC-FI was assessed at baseline. A semi-quantitative method was utilized to evaluate the prevalence of VF on lateral thoracolumbar radiographs. Univariate and multivariate regression analyses were performed adjusting for age, body mass index (BMI), SLE duration, cumulative glucocorticoid dose, bisphosphonate use, and BMD measurements. We included 202 women with SLE (mean age [SD] = 43.3 [13.6] years). The mean (SD) SLICC-FI value was 0.14 (0.09). Eleven (5.4%) patients were categorized as robust, 62 (30.7%) as relatively less fit, 84 (41.6%) as least fit, and 45 (22.3%) as frail. Both univariate and multivariate models showed associations between frailty (defined as SLICC-FI > 0.21) and prevalent VF in the entire population (OR 5.76, 95% CI 2.53-13.12; P < 0.001) and in the premenopausal group (OR 4.29, 95% CI; P = 0.047). We also found an association between the SLICC-FI and low BMD. In conclusion, frailty assessed by SLICC-FI might be associated with VF and low BMD in mestizo females with SLE.

Cost-related prescription non-adherence and patient-reported outcomes in systemic lupus erythematosus: The Michigan Lupus Epidemiology & Surveillance program.

Medication access and adherence play key roles in determining patient outcomes. We investigated whether cost-related non-adherence (CRNA) to prescription medications was associated with worse patient-reported outcomes in a population-based systemic lupus erythematosus (SLE) cohort. Sociodemographic and prescription data were collected by structured interviews in 2014-2015 from patients meeting SLE criteria in the established Michigan Lupus Epidemiology & Surveillance (MILES) Cohort. We examined the associations between CRNA and potential confounders such as sociodemographics and health insurance coverage, and outcome measures of SLE activity and damage using multivariable linear regression. 462 SLE participants completed the study visit: 430 (93.1%) female, 208 (45%) Black, and mean age 53.3years. 100 (21.6%) participants with SLE reported CRNA in the preceding 12months. After adjusting for covariates, CRNA was associated with both higher levels of current SLE disease activity [SLAQ: β coeff 2.7 (95% CI 1.3, 4.1), p < 0.001] and damage [LDIQ β coeff 1.4 (95% CI 0.5, 2.4), p = 0.003]. Race, health insurance status, and fulfilling Fibromyalgia (FM) Survey Criteria were independently associated with both higher (worse) SLAQ and LDIQ scores; female sex was further associated with higher SLAQ scores. Patients with SLE who reported CRNA in the previous 12months had significantly worse self-reported current disease activity and damage scores compared to those not reporting CRNA. Raising awareness and addressing barriers or concerns related to financial implications and accessibility issues in care plans may help to improve these outcomes.
