Peptidoglycan Amplifies CD4+ T Cell Activation by MHCII+ Fibroblast-like Synoviocytes in an in Vitro Model of Lyme Arthritis
Background/Purpose: Lyme arthritis (LA), caused by infection with Borrelia burgdorferi (Bb), is characterized by proliferative synovitis accompanied by dysregulated autoimmune Th1 responses. Fibroblast-like synoviocytes (FLS)…Abstract Number: 0062 • ACR Convergence 2020
The Role of PGLYRP1 in the Pathogenesis of Lyme Disease
Background/Purpose: Lyme Disease is caused by the spirochete Borrelia Burgdorferi (Bb). The infection often begins in the skin, following a tick bite, and spreads to…Abstract Number: 951 • 2018 ACR/ARHP Annual Meeting
IFN-Gamma Production in Lyme Arthritis Synovial Tissue Promotes Differentiation of Fibroblast-like Synoviocytes into Inflammatory Effector Cells
Background/Purpose: Lyme arthritis (LA), a late-disease manifestation of Borrelia burgdorferi infection, usually responds to antibiotic therapy. However, some patients may develop a proliferative synovitis lasting…Abstract Number: 1029 • 2018 ACR/ARHP Annual Meeting
Fibroblast-like Synoviocytes As Immune Effectors in the Pathogenesis of Synovial Lesion in Antibiotic-Refractory Lyme Arthritis
Background/Purpose: Antibiotic-refractory Lyme arthritis (LA) is characterized by marked proliferative synovitis that persists for months-to-years after oral and IV antibiotic therapy for Borrelia burgdorferi. Although…Abstract Number: 947 • 2018 ACR/ARHP Annual Meeting
Clinical Characteristics and Outcome after Treatment of a National Cohort of PCR-Positive Lyme Arthritis
Background/Purpose: Lyme arthritis (LA) is a disseminated Borrelia infection whom prevalence is lower in Europe than in the USA, probably because of difference in Borrelia…Abstract Number: 950 • 2018 ACR/ARHP Annual Meeting
Ultrasonographic Examinations Show Highly Prevalent Abnormalities of Hamstring Tendons in Lyme Arthritis Patients
Background/Purpose: Lyme arthritis (LA), the most common late manifestation of Lyme disease, usually occurs months to up to 2 years after the initial infection. Joint…Abstract Number: 1020 • 2017 ACR/ARHP Annual Meeting
The Inflammatory and Proliferative Synovial Lesion in Post-Infectious Lyme Arthritis Results from Impaired Wound Healing
Background/Purpose: Lyme arthritis (LA) is initially triggered by Borrelia burgdorferi infection, but in some patients, the synovitis persists despite 2-3 months of antibiotic therapy and…Abstract Number: 946 • 2016 ACR/ARHP Annual Meeting
Comparative Effectiveness of Second-Line Treatment Strategies for Lyme Arthritis in Children
Background/Purpose: First-line treatment for Lyme arthritis is fairly standardized, but second-line strategies are more variable. We compared the effectiveness of oral antibiotics, intra-articular glucocorticoid injections (IAGC),…Abstract Number: 1326 • 2016 ACR/ARHP Annual Meeting
Autoimmune Arthritides, Rheumatoid Arthritis, Psoriatic Arthritis, or Peripheral Spondyloarthropathy, Following Lyme Disease
Background/Purpose: Lyme arthritis (LA) usually responds to antibiotic therapy, though immune-mediated synovitis may persist after antibiotic treatment, usually confined to a previously infected joint,…Abstract Number: 1101 • 2015 ACR/ARHP Annual Meeting
Matrix Metalloproteinase-10 (Stromelysin 2) Is a Target of Robust Autoimmune T and B Cell Responses in Antibiotic-Refractory Lyme Arthritis, but Not in Rheumatoid Arthritis
Background/Purpose: Infection-induced autoimmunity has been hypothesized to have a pathogenic role in antibiotic-refractory Lyme arthritis (LA). We previously identified 3 autoantigens, endothelial cell growth factor,…Abstract Number: 1244 • 2015 ACR/ARHP Annual Meeting
Extracellular MicroRNAs in Synovial Fluid Reveal a Marked Proliferative Signature in Patients with Antibiotic-Refractory Lyme Arthritis
Background/Purpose: Lyme arthritis (LA), caused by a tick-borne spirochete Borrelia burgdorferi, usually resolves appropriately with antibiotic treatment, called antibiotic-responsive LA. However, in some patients, arthritis…Abstract Number: 1367 • 2015 ACR/ARHP Annual Meeting
Fibroblast-like Synoviocytes Shape and Perpetuate the Inflammatory Immune Responses Associated with Antibiotic-Refractory Lyme Arthritis.
Background/Purpose: Antibiotic-refractory Lyme arthritis is defined as persistent synovitis for months to years after antibiotic therapy for Borrelia burgdorferi, the causative agent of Lyme disease.…Abstract Number: 2161 • 2014 ACR/ARHP Annual Meeting
Interest of Systematic Lyme Serology in Context of Recent Onset Arthritis
Background/Purpose Lyme arthritis is a late manifestation of a tick-transmitted spirotechal infection, mainly caused by Borrelia burdorgferi. Lyme arthritis typically presents as a mono- or…Abstract Number: 1970 • 2014 ACR/ARHP Annual Meeting
TH17 Inflammatory Responses Occur in a Subset of Patients with Erythema Migrans or Lyme Arthritis, but Are Not Predominant Responses in Joints
Background/Purpose Lyme disease usually begins with an expanding skin lesion, erythema migrans (EM), whereas arthritis is a late disease manifestation. The infection usually resolves with…Abstract Number: 984 • 2014 ACR/ARHP Annual Meeting
Apolipoprotein B Is a Target of T and B Cell Responses in a Subgroup of Patients with Lyme Disease
Background/Purpose Borrelia burgdorferi-induced autoimmunity in affected joints has been hypothesized to be a contributing factor to antibiotic-refractory Lyme arthritis (ARLA). Our prior study, which combined…
