Objective: One key target of treating patients with systemic lupus erythematosus (SLE) is to prevent organ damage. This analysis quantified the association between time spent in four specific SLE low disease activity (LDA) states and organ damage rate.

Methods: This retrospective real-world data analysis (GSK Study 207168), undertaken to help contextualise the BLISS-BELIEVE clinical trial, included adults with SLE enrolled for≥1 year in the Hopkins Lupus Cohort and treated with standard therapy in a specialist care centre between 1987 and 2019.

Background: Interstitial fibrosis in lupus nephritis (LN) is often infiltrated by immune cells but typically regarded as nonspecific "scar reaction." This study aimed to investigate the relationship between inflammatory fibrosis and kidney disease progression in LN.

Methods: Interstitial fibrosis and tubular atrophy (IFTA) were scored in 124 LN kidney biopsies.

Article Synopsis
  • Systemic lupus erythematosus (SLE) is an autoimmune disease with diverse effects on different organs, and this study aims to understand how histone modifications impact disease persistence and cell-specific responses among patients.
  • Analysis of samples from 20 SLE patients and 8 controls revealed significant variability in chromatin marks across T cells, B cells, and monocytes, with certain pathways like TNF and IL-2/STAT5 showing greater consistency across these cell types.
  • The findings suggest that although each type of immune cell is affected differently, classical inflammatory pathways, particularly NFκB and IL-6 signaling, are common themes in the disease mechanisms associated with SLE.

Article Synopsis
  • - This study examined the occurrence and effects of antinuclear antibodies (ANA) in patients with antiphospholipid antibodies (aPL) but without other systemic autoimmune diseases, using data from the APS ACTION Registry.
  • - Among the 430 analyzed patients, 56% tested positive for ANA, revealing significant links between ANA positivity and various autoimmune features like hematologic issues and joint involvement.
  • - Despite the presence of these autoimmune characteristics in ANA-positive patients, the study found no connection between ANA status and complications related to thrombosis or pregnancy; interestingly, ANA-negative patients had more pregnancies and live births.

Objectives: To evaluate urinary activated leucocyte cell adhesion molecule (ALCAM) and CD6 as predictors of lupus nephritis (LN) progression or disease resolution across a 1-year study.

Methods: Serum and urine samples from biopsy proven LN subjects (n = 122) were prospectively collected over the course of a year at 3- or 6-month intervals (weeks 0, 12, 26, and 52) across multiple study sites and assessed for soluble ALCAM and CD6 levels. Urine creatinine from the same urine sample was used to normalize the levels of urinary ALCAM and urinary CD6.
