Objective: Black people in the USA have a higher incidence and severity of SLE and worse outcomes, yet they are significantly under-represented in SLE clinical trials. We assessed racial differences in clinical trial perceptions among a large cohort of predominantly Black people with SLE.

Methods: Georgians Organised Against Lupus (GOAL) is a population-based, prospective cohort of people with a validated diagnosis of SLE living in Atlanta.

Background: Lupus nephritis (LN) occurs in <40% of patients with SLE. Reliable biomarkers of kidney damage are needed to identify patients with SLE at risk of developing LN to improve screening, treat the disease earlier, and halt progression to kidney failure. Novel biomarkers of extracellular matrix remodeling were evaluated as markers of kidney fibrosis and disease activity in patients with LN.

Article Synopsis
  • - The study investigates the link between glucocorticoid (GC) exposure and the risk of irreversible organ damage in patients with systemic lupus erythematosus (SLE), emphasizing the importance of managing GC use effectively.
  • - Researchers conducted a literature review and analyzed 49 studies involving over 16,000 SLE patients to assess how different levels of GC exposure correlate with specific organ damage outcomes over an average follow-up of about 105 months.
  • - Findings revealed that higher daily GC doses were connected to increased occurrences of cardiovascular issues, osteoporosis with fractures, and osteonecrosis, suggesting the need for careful management of GC therapy in SLE patients to balance treatment benefits and potential harm.

Objective: To determine whether and how cognitive assessment data should be included in a report for patients with SLE and their providers.

Methods: Leveraging experiences from prior studies, we created a cognitive report that included a hypothetical patient's results on tests of multiple domains based on the NIH Toolbox Fluid Cognition Battery. In focus groups that comprised patients with SLE (two groups) and their providers (two groups), feedback was sought on the presentation of results as well as the potential value of the report in the clinical setting.

Objectives: To describe glucocorticoid (GC) use in the SLICC inception cohort and to explore factors associated with GC use. In particular we aimed to assess temporal trends in GC use and to what extent physician-related factors may influence use.

Methods: Patients were recruited within 15 months of diagnosis of SLE from 33 centres between 1999 and 2011 and continue to be reviewed annually.

Background: Patients with end-stage renal disease (ESRD) due to lupus nephritis (LN-ESRD) may be followed by multiple providers (nephrologists and rheumatologists) and have greater opportunities to receive recommended ESRD-related care. We aimed to examine whether LN-ESRD patients have better quality of ESRD care compared to other ESRD patients.

Methods: Among incident patients (7/05-9/11) with ESRD due to LN (n = 6,594) vs.

This study was undertaken to investigate immunopathologic mechanism of Enterococcus faecalis in relation to persistent apical periodontitis. We monitored the expression levels of alpha4 integrin in human polymorphonuclear neutophils (PMNs) after stimulated with sonicated extracts of E. faecalis (SEF) and compared with lipopolycaccarides (LPS) of Escherichia coli for various incubation time.

In the present authors' previous study, sonicated Enterococcus faecalis extracts were shown to suppress the cell cycle progression of human lymphocytes. To study the effect of this microorganism on the function of lymphocytes, the authors investigated the levels of interleukin-2 (IL-2) and interleukin-4 (IL-4) production by T lymphocytes before and after the addition of sonicated E. faecalis extracts.

The purpose of this study was to examine whether the sonicated extract of Enterococcus faecalis (SEF) alters the cell cycle transition of lymphocytes and thus regulates the fate of the arrested cells. Human lymphocytes were activated by phytohemagglutinin in the presence or absence of SEF, and cell cycle was assessed by flow cytometry. Seventy-two hours after activation with phytohemagglutinin, cells were activated from G0/G1 to S (6.

This study was undertaken to investigate the capacity of polymorphonuclear neutrophils (PMNs) to secrete Macrophage Inflammatory Protein (MIP)-1alpha and MIP-1beta after stimulation with Porphyromonas endodontalis lipopolysaccharide (LPS). Escherichia coli LPS was used as a positive control. Venous blood was collected and PMNs were isolated from healthy volunteers.

The purpose of this study was to evaluate the tissue levels of matrix metalloproteinase (MMP)-1, -2, -3 and their distributions in inflamed human dental pulps and periapical lesions. Samples were subjected to enzyme-linked immunosorbent assay and/or immunohistochemistry by using specific antibodies to MMP-1, -2, and -3. Results from enzyme-linked immunosorbent assay were analyzed by using the Mann-Whitney U test and presented as p values.

The objective of this study was to investigate the expression of surface markers on T lymphocytes and the Th1/Th2 immune response in pulpal inflammation associated with specific bacteria. Pulpal inflammation was experimentally induced in rat mandibular incisors by drilling, without coolant, to open pulp chambers. Streptococcus mutans (S.
