In the general human population, aging is associated with a rise in systemic inflammation, primarily involving innate immune pathways related to interferon (IFN), toll-like receptor, and cytokine signaling. In systemic lupus erythematosus (SLE), a prototypical systemic autoimmune disease, aging is distinctly associated with improvements in disease activity, suggesting a unique relationship between aging and inflammation in this disease. Using a multi-omic approach incorporating transcriptional profiling, single cell RNA sequencing, proteomics and methylation analysis, we studied age-related changes in the immune profiles of 287 SLE patients between 20 and 83 years old, and compared the results against 928 healthy controls aged between 21 and 89 years old.

This has made it challenging to understand drivers of long-term SLE outcomes. Our objective was to identify whether changes in DNA methylation over time, in an actively flaring SLE cohort, were associated with remission and whether these changes meaningfully subtype SLE patients.

Methods: We used data from the California Lupus Epidemiology Study to examine the following measures of frailty: Systemic Lupus International Collaborating Clinics (SLICC) Frailty Index (SLICC-FI), Short Physical Performance Battery (SPPB), and Fatigue, Resistance, Ambulation, Illness, and Loss of Weight (FRAIL) scale questionnaire.

Objective: Glucocorticoids (GCs) can be beneficial from both clinical and patient perspectives, but side effects are well documented. We examined patterns of GC use over 15 years (2006-2021) and occurrence of adverse health conditions (AHCs) and health care use by GC exposure in two longitudinal cohorts with systemic lupus erythematosus (SLE).
Methods: Data from the Lupus Outcomes Study (LOS; 2003-2015) and FORWARD cohort (2015-2021) were used.
Objective: Trauma history is associated with SLE onset and worse patient-reported outcomes; perceived stress is associated with greater SLE disease activity. Stress perceptions vary in response to life events and may be influenced by psychosocial factors. In an SLE cohort, we examined whether stressful events associated with perceived stress, whether psychosocial factors affected perceived stress, and whether these relationships varied by prior trauma exposure.

Methods: Cross-sectional data from a prospective single-center cohort (2015 to 2022) of patients with iRMDs were used to evaluate 3 co-primary outcomes: BMD of the left femoral neck and the lumbar spine (as T-scores) and the TBS. Inverse probability weighting adjusted for numerous confounders including age, sex, body mass index, current and cumulative glucocorticoid (GC) dose, C-reactive protein levels, disability, and others.
Objective: Cognitive impairment is a common complaint in SLE, but approaches to measuring cognitive performance objectively vary. Leveraging data collected in a population-based cohort of individuals with validated SLE, we compared performance and potential impairment across multiple measures of cognition.
Methods: During a single study visit (October 2019-May 2022), times to complete the Trail Making Test B (TMTB; N=423) were recorded; potential impairment was defined as an age-corrected and education-corrected T-score <35 (>1.

Objective: We sought to describe fluid cognition and its correlates among individuals with systemic lupus erythematosus (SLE).
Methods: Participants (n = 199) were recruited from a population-based cohort for a single study visit (October 2019 to May 2022). Fluid cognition was measured via the National Institutes of Health Toolbox Fluid Cognition Battery (including episodic memory, working memory, attention and inhibitory control, processing speed, and cognitive flexibility domains) and expressed as age-corrected standard scores (mean 100, SD 15).
Objective: Cognitive impairment (CI) is one of the most common manifestations of Neuropsychiatric Systemic Lupus Erythematosus (NPSLE). Despite its frequency, we have a limited understanding of the underlying immune mechanisms, resulting in a lack of pathways to target. This study aims to bridge this gap by investigating differences in serum analyte levels in SLE patients based on their cognitive performance, independently from the attribution to SLE, and exploring the potential for various serum analytes to differentiate between SLE patients with and without CI.

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.

Methods: An expert workgroup composed of physician, patient, and researcher representatives convened to identify patient-reported outcome (PRO) domains of greatest importance to people with SLE. A patient advisory panel separately ranked domains.
Patient-reported outcome measures (PROMs) provide a standardized assessment from the patient about their own health status. Although originally developed as research tools, PROMs can be used in clinical care to complement objective functional measures (eg, range of motion) and are increasingly integrated to guide treatment decisions and predict outcomes. In some situations, when PROMs are used during clinical care they can improve patient mortality, outcomes, engagement, well-being, and patient-physician communication.

In this pilot study, we explore a hypothesis-free approach that can measure thousands of exogenous chemicals in blood ("exposome") in patients with SLE and unaffected controls.
Methods: This cross-sectional study analyzed a cohort of patients with prevalent SLE (n = 285) and controls (n = 106).

Objective: Rural residence has been associated with health disparities in rheumatic diseases and other chronic conditions in the United States. This study aimed to determine if a relationship exists between geographic residence and health care utilization outcomes for people with rheumatoid arthritis (RA) and osteoarthritis (OA) in a US-wide rheumatic disease registry.
Methods: Participants were in FORWARD, The National Databank for Rheumatic Diseases, a US-wide rheumatic disease longitudinal cohort completing questionnaires between 1999 and 2019.
Objective: Concerns about the affordability of medications are common in systemic lupus erythematosus (SLE), but the relationship between medication cost concerns and health outcomes is poorly understood. We assessed the association of self-reported medication cost concerns and patient-reported outcomes (PROs) in a multiethnic SLE cohort.
Methods: The California Lupus Epidemiology Study is a cohort of individuals with physician-confirmed SLE.
Purpose: Patient-reported outcome measures (PROMs) are used commonly to assess function to direct treatment and evaluate outcomes for patients with distal radius fractures. Most PROMs have been developed and validated in English with minimal report of the demographics of patients studied. The validity of applying these PROMs among Spanish-speaking patients is unknown.
