Introduction: Mild cognitive impairment (MCI) is a prodromal stage of dementia. Understanding the mechanistic changes from healthy aging to MCI is critical for comprehending disease progression and enabling preventative intervention.
Methods: Patients with MCI and age-matched controls (CN) were administered cognitive tasks during functional near-infrared spectroscopy (fNIRS) recording, and changes in plasma levels of extracellular vesicles (EVs) were assessed using small-particle flow cytometry.
SLE is a clinically heterogeneous disease characterized by an unpredictable relapsing-remitting disease course. Although the etiology and mechanisms of SLE flares remain elusive, Epstein-Barr virus (EBV) reactivation is implicated in SLE pathogenesis. This study examined the relationships between serological measures of EBV reactivation, disease activity, and interferon (IFN)-associated immune pathways in SLE patients.

SLE occurs primarily in females of childbearing age, with increased prevalence and severity in minority populations. Despite improvements in treatment modalities, SLE patients frequently experience periods of heightened disease activity and flare that can lead to permanent organ damage, increased morbidity, and early mortality.
View Article and Find Full Text PDFPurpose Of Review: To summarize current knowledge of the impact of coronavirus disease 19 (COVID-19) on patients with systemic lupus erythematosus (SLE).
Recent Findings: Several observational studies, including case series, patient surveys, and patient registries, have examined the incidence and severity of COVID-19 in patients with SLE. Due to methodologic limitations (focus on sicker patients, exclusion of asymptomatic or mild cases, limited or inaccurate viral testing), it is difficult to determine the risk and outcomes of COVID-19 in SLE patients.
Objective: Although SLE disproportionately affects minority racial groups, they are significantly under-represented in clinical trials in the USA. This may lead to misleading conclusions in race-based subgroup analyses. We conducted focus groups to evaluate the perceptions of diverse patients with lupus about clinical trial participation.

Methods: Adult SLE patients ( = 198) provided plasma, serum, and RNA.
Objective: Existing methods for grading lupus flares or improvement require definition-based thresholds as increments of change. Visual analogue scales (VAS) allow rapid, continuous scaling of disease severity. We analysed the performance of the SELENA SLEDAI Physician's Global Assessment (SSPGA) and the Lupus Foundation of America-Rapid Evaluation of Activity in Lupus (LFA-REAL) as measures of improvement or worsening in SLE.

Methods: Patients with SLE (185) with moderate to severe disease activity and positive interferon (IFN) gene signature were randomised to receive IFN-K or PBO intramuscular injections (days 0, 7 and 28 and W12 and W24). Coprimary endpoints at W36 were neutralisation of IFN gene signature and the BILAG-Based Composite Lupus Assessment (BICLA) modified by mandatory corticosteroid (CS) tapering.
Purpose Of Review: To review progress in the field of clinical trials for SLE.
Recent Findings: Treatment development for SLE has been marked by failures of many later phase studies, representing billions of dollars of lost research and development funding. Recently, more successful Phase II trials have tested reductions in background medications, novel stringent endpoints, and identification of informative immunologic subsets to achieve greater treatment effects.
Objective: Molecular medicine raised expectations for strategically targeted biologic agents in systemic lupus erythematosus (SLE), but clinical trial results have been disappointing and difficult to interpret. Most studies add investigational agents to various, often effective, standard therapy immunosuppressants used at baseline, with unknown treatment interactions. Eliminating polypharmacy in trials of active lupus remains controversial.
View Article and Find Full Text PDFBackground: Decreased heart rate variability (HRV) is associated with adverse outcomes in cardiovascular diseases and has been observed in patients with systemic lupus erythematosus (SLE). We examined the relationship of HRV with SLE disease activity and selected cytokine pathways.
Methods: Fifty-three patients from the Oklahoma Lupus Cohort were evaluated at two visits each.
Objective: To develop a simple systemic lupus erythematosus (SLE) severity index that requires knowledge of only American College of Rheumatology (ACR) criteria and subcriteria.
Methods: This study used demographic, mortality and medical records data of 1915 patients with lupus from the Lupus Family Registry and Repository. The data were randomly split (2:1 ratio) into independent training and validation sets.
Objectives: TO COMPARE TWO MEASURES OF SYSTEMIC LUPUS ERYTHEMATOSUS (SLE) RESPONSE: the British Isles Lupus Assessment Group (BILAG)-based Composite Lupus Assessment (BICLA) and the Systemic Lupus Responder Index (SRI) against a clinician's assessment of improvement.
Methods: Ninety-one lupus patients were identified with two visits at which Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and BILAG had been scored and with active disease (SLEDAI≥6) at the first visit. A physician rated the disease activity at the second visit as clinically significant improvement, no change or worsening.
Objective: Accurate assessment of lupus flares is critical but problematic in clinical trials. This study examined the impact of modifications to the classic Safety of Estrogens in Lupus Erythematosus National Assessment (SELENA)-SLEDAI flare index (cSFI).
Methods: Ninety-one SLE patient records were evaluated at two visits at which the SLEDAI and BILAG had been scored prospectively.

Despite rapid accumulation of knowledge about complex immune dysregulation in systemic lupus erythematosus (SLE) and major primary lupus syndromes, and a plethora of promising new treatments reaching preclinical and early clinical studies, advanced-phase trials of new biologic agents have repeatedly failed to achieve their clinical end points. It is possible that none of these agents work, but the accuracy of this suggestion is as unclear as the case for efficacy, owing to issues in the design of studies and the opacity of the data that have resulted. Disease heterogeneity and complexity might be a hurdle that is simply too high to overcome by existing methodological approaches, and the way forward to interpretable trial results remains unclear.

View Article and Find Full Text PDFAccurately measuring lupus disease activity has been a demanding and still unresolved task, considering the complex multisystem nature of the disease and its variability over time and between patients. Various available tools for measurement of lupus disease activity may detect clinical improvement and/or deterioration and can be global or organ-focused. Several measures have demonstrated validity, reliability, and sensitivity to change in observational studies, and some were found useful in randomized controlled trials.
