Abstract Objective The objective of this study was to examine the clinical outcomes during the implementation of a self-administered patient decision-aid (PtDA) for lupus. Methods We provided an effective computerized lupus PtDA in 15 rheumatology outpatient clinics 2019–2024 (including the COVID pandemic). We undertook Organizational Readiness to Implement Change Surveys (ORICs) and Team Learning and Psychological Safety Surveys (TLPSSs) at baseline. The primary study outcome objective measure, percent penetration/reach, was defined as the number of patients who viewed the lupus PtDA at the end of the study, divided by the total number of eligible patients (times 100). We used validated clinical personnel surveys to examine the perceived lupus PtDA appropriateness, acceptability, feasibility, success, and permanence, at 4 months, 12 months and 24 months post-PtDA implementation. Results Among the sites, the clinical personnels’ (n = 184) baseline ORIC commitment and efficacy scores (a 0–5 scale, higher = better) ranged from 3.5 to 4.2, and 3.4 to 4.4, respectively; the TLPSS scores (a 0–7 scale, higher = better) were 3.9–5.5 for internal learning, 3.7–5.6 for external learning, and 4.3–5.5 for psychological safety. The penetration (primary outcome) among 15 geographically diverse US rheumatology clinics ranged from 3% to 44%. We found that the total number of providers in the clinic was positively associated with higher penetration. Clinical personnel–perceived lupus PtDA outcomes were optimal at 4 months (all scale scores ranged from 1 to 5, higher = better): (i) appropriateness, 3.43 (s.d. 0.86); (ii) acceptability, 3.53 (s.d. 0.83); (iii) feasibility, 3.44 (s.d. 0.71); (iv) success, 3.41 (s.d. 0.73); and (v) permanence, 3.22 (s.d. 0.74). Conclusion We implemented a lupus PtDA with varied success rates during the COVID pandemic; more providers were associated with higher clinic penetration. Clinical personnel perceived high lupus PtDA appropriateness, acceptability, feasibility, success, and permanence that persisted up to 24 months.

Objective Social determinants of health (SDoH) likely contribute to outcome disparities in lupus nephritis (LN). Understanding the overall burden and contribution of each domain could guide future health equity–focused interventions to improve outcomes and reduce disparities in LN. Objectives of this meta‐analysis were to 1) determine the association of overall SDoH and specific SDoH domains on LN outcomes and 2) develop a framework for the multidimensional impact of SDoH on LN outcomes. Methods We performed a comprehensive search of studies measuring associations between SDoH and LN outcomes. We examined pooled odds of poor LN outcomes including death, end‐stage kidney disease, or cardiovascular disease in patients with and without adverse SDoH. Additionally, we calculated the pooled odds ratios of outcomes by four SDoH domains: individual (eg, insurance), health care (eg, fragmented care), community (eg, neighborhood socioeconomic status), and health behaviors (eg, smoking). Results Among 531 screened studies, 31 meeting inclusion criteria and 13 with raw data were included in meta‐analysis. Pooled odds of poor outcomes were 1.47‐fold higher in patients with any adverse SDoH. Patients with adverse SDoH in individual and health care domains had 1.64‐fold and 1.77‐fold higher odds of poor outcomes. We found a multiplicative impact of having two or more adverse SDoH on LN outcomes. Black patients with public insurance and fragmented care had 12‐fold higher odds of poor LN outcomes. Conclusion Adverse SDoH is associated with poor LN outcomes. Having two or more adverse SDoH, specifically in different SDoH domains, had a multiplicative impact leading to worse LN outcomes, widening disparities. image

Objective Determinants of the increased risk of diffuse large B-cell lymphoma (DLBCL) in SLE are unclear. Using data from a recent lymphoma genome-wide association study (GWAS), we assessed whether certain lupus-related single nucleotide polymorphisms (SNPs) were also associated with DLBCL. Methods GWAS data on European Caucasians from the International Lymphoma Epidemiology Consortium (InterLymph) provided a total of 3857 DLBCL cases and 7666 general-population controls. Data were pooled in a random-effects meta-analysis. Results Among the 28 SLE-related SNPs investigated, the two most convincingly associated with risk of DLBCL included the CD40 SLE risk allele rs4810485 on chromosome 20q13 (OR per risk allele=1.09, 95% CI 1.02 to 1.16, p=0.0134), and the HLA SLE risk allele rs1270942 on chromosome 6p21.33 (OR per risk allele=1.17, 95% CI 1.01 to 1.36, p=0.0362). Of additional possible interest were rs2205960 and rs12537284. The rs2205960 SNP, related to a cytokine of the tumour necrosis factor superfamily TNFSF4, was associated with an OR per risk allele of 1.07, 95% CI 1.00 to 1.16, p=0.0549. The OR for the rs12537284 (chromosome 7q32, IRF5 gene) risk allele was 1.08, 95% CI 0.99 to 1.18, p=0.0765. Conclusions These data suggest several plausible genetic links between DLBCL and SLE.

In 2012, the Systemic Lupus International Collaborating Clinics (SLICC) group published a new set of classification criteria for systemic lupus erythematosus (SLE). Studies applying these criteria to real-life scenarios have found either equal or greater sensitivity and equal or lower specificity to the 1997 ACR classification criteria (ACR 97). Nonetheless, there are no studies that have used the SLICC 12 criteria to investigate the incidence of lupus. We used the resource of the Rochester Epidemiology Project to identify incident SLE patients in Olmsted County, Minnesota, from 1993 to 2005, who fulfilled the ACR 97 or SLICC 12 criteria. A total of 58 patients met criteria by SLICC 12 and 44 patients met criteria by ACR 97. The adjusted incidence of 4.9 per 100,000 person-years by SLICC 12 was higher than that by ACR 97 (3.7 per 100,000 person-years, p = 0.04). The median duration from the appearance of first criterion to fulfillment of the criteria was shorter for the SLICC 12 than for ACR 97 (3.9 months vs 8.1 months). The higher incidence by SLICC 12 criteria came primarily from the ability to classify patients with renal-limited disease, the expansion of the immunologic criteria and the expansion of neurologic criteria.

Objective Lupus nephritis (LN) is a severe manifestation of systemic lupus erythematosus (SLE) that exhibits familial aggregation and may progress to end‐stage renal disease (ESRD). LN is more prevalent among African Americans than among European Americans. This study was undertaken to investigate the hypothesis that the apolipoprotein L1 gene ( APOL1 ) nephropathy risk alleles G1/G2, common in African Americans and rare in European Americans, contribute to the ethnic disparity in risk. Methods APOL1 G1 and G2 nephropathy alleles were genotyped in 855 African American SLE patients with LN‐ESRD (cases) and 534 African American SLE patients without nephropathy (controls) and tested for association under a recessive genetic model, by logistic regression. Results Ninety percent of the SLE patients were female. The mean ± SD age at SLE diagnosis was significantly lower in LN‐ESRD cases than in SLE non‐nephropathy controls (27.3 ± 10.9 years versus 39.5 ± 12.2 years). The mean ± SD time from SLE diagnosis to development of LN‐ESRD in cases was 7.3 ± 7.2 years. The G1/G2 risk alleles were strongly associated with SLE‐ESRD, with 25% of cases and 12% of controls having 2 nephropathy alleles (odds ratio [OR] 2.57, recessive model P = 1.49 × 10 −9 ), and after adjustment for age, sex, and ancestry admixture (OR 2.72, P = 6.23 × 10 −6 ). The age‐, sex‐, and admixture‐adjusted population attributable risk for ESRD among patients with G1/G2 polymorphisms was 0.26, compared to 0.003 among European American patients. The mean time from SLE diagnosis to ESRD development was ∼2 years earlier among individuals with APOL1 risk genotypes ( P = 0.01). Conclusion APOL1 G1/G2 alleles strongly impact the risk of LN‐ESRD in African Americans, as well as the time to progression to ESRD. The high frequency of these alleles in African Americans with near absence in European Americans explains an important proportion of the increased risk of LN‐ESRD in African Americans.
