Lack of Association Between Cognitive Test Performance and Cognitive Symptoms in Systemic Lupus Erythematosus (SLE)
Background/Purpose: Cognitive dysfunction (CD) is reported to affect approximately 40% of SLE patients (1). Mood disorders have been associated with both cognitive symptoms and cognitive…Abstract Number: 0885 • ACR Convergence 2021
SLE Phenotypes Formed from Machine Learning and Their Associations with Cognitive Impairment
Background/Purpose: Cognitive impairment (CI) in SLE is a significant problem with limited treatment options. This is in part due to the uncertainty regarding the multifaceted…Abstract Number: 0887 • ACR Convergence 2021
Association of Mycophenolate and Azathioprine Use with Cognitive Function in SLE
Background/Purpose: Cognitive dysfunction (CD) is a common manifestation of systemic lupus erythematosus (SLE) which can have detrimental consequences for those affected. To date, no treatments…Abstract Number: 0889 • ACR Convergence 2021
Association of Subjective Cognitive Report Using PDQ-20 to a Neuropsychological Battery in a Cohort of SLE Patients
Background/Purpose: Systemic Lupus Erythematosus (SLE) can lead to a number of neuropsychiatric manifestations including cognitive impairment (CI). Previous meta-analyses have reported the prevalence of CI…Abstract Number: 0892 • ACR Convergence 2021
Screening for Cognitive Impairment with the Automated Neuropsychological Assessment Metrics in Patients with Systemic Lupus Erythematosus
Background/Purpose: The American College of Rheumatology Neuropsychological Battery (ACR-NB) is the standard screening test for cognitive impairment (CI) in systemic lupus erythematosus (SLE). While the…Abstract Number: 1300 • ACR Convergence 2020
Identifying Cognitive Impairment in Patients with Systemic Lupus Erythematosus Using Hidden Markov Models: A Bayesian Approach
Background/Purpose: Cognitive impairment (CI) is usually operationalized on the American College of Rheumatology Neuropsychological Battery (ACR-NB) as a z-score of ≤-1.5 on ≥2 domains or…Abstract Number: 1688 • ACR Convergence 2020
Long-term Hearing Loss, Anxiety and Neurodevelopmental Outcomes Following Kawasaki Disease: A Population-based Cohort Study
Background/Purpose: The incidence of Kawasaki disease (KD) is increasing in Ontario. Cardiovascular sequelae following KD are well-described. However, there are limited and conflicting non-cardiovascular outcome…Abstract Number: 1788 • ACR Convergence 2020
Assessment of the Impact of Interferon Levels on Cognitive Dysfunction in Patients with SLE
Background/Purpose: Cognitive impairment (CI) is among the earliest and the most prevalent manifestations of SLE. Previous studies have demonstrated that the increased levels of interferon…Abstract Number: 1804 • ACR Convergence 2020
Impact of the Kynurenine/Tryptophan Pathway on Cognitive Dysfunction and Depression in Systemic Lupus Erythematosus
Background/Purpose: Tryptophan (TRP) is metabolized to kynurenine (KYN), quinolonic acid [QA, a N-methyl D-aspartate receptor (NMDAR) agonist] and kynurenic acid (KA, an NMDAR antagonist). KYN/TRP…Abstract Number: 1806 • ACR Convergence 2020
The Association of Interferon-α with Kynurenine/Tryptophan Pathway Activation in Systemic Lupus Erythematosus
Background/Purpose: Type I IFN contributes to SLE pathogenesis and stimulates the kynurenine/tryptophan (KYN/TRP) pathway, producing elevated quinolinic acid (QA) levels relative to kynurenic acid (KA)…Abstract Number: 1819 • ACR Convergence 2020
Altered Brain Functional Connectivity in Systemic Lupus Erythematosus
Background/Purpose: Cognitive dysfunction (CD) is very prevalent in SLE and significantly affects quality of life. Altered functional brain mechanisms are associated with CD in SLE.…Abstract Number: 0026 • ACR Convergence 2020
A Modified Version of the 2016 ACR Fibromyalgia Criteria Cognitive Items Results in Stronger Correlation Between Subjective and Objective Measures of Cognitive Impairment
Background/Purpose: In a previous study, we showed that the subjective item assessing cognitive impairment (SSS-Cog) for fibromyalgia (FM) did not correlate with objective cognitive measures.…
