Objective: Axial spondyloarthritis (axSpA) is an inflammatory disease in which overactive interleukin (IL)-17A-producing cells are implicated in a central role. Therapeutically, biologics that target IL-17A, such as secukinumab, have demonstrated improved clinical outcomes. Despite this translational success, there is a gap in understanding why some patients with axSpA do not respond to IL-17A-blocking therapy. Our study aims to discriminate immune profiles between secukinumab responders (SEC-R) and nonresponders (SEC-NR).
Methods: Peripheral blood mononuclear cells were collected from 30 patients with axSpA before and 24 weeks after secukinumab treatment. Frequency of CD4+ subsets were compared between SEC-R and SEC-NR using flow cytometry. Mature CD45RO+CD45RA-CD4+ T cells were fluorescent-activated cell sorting sorted, and RNA was measured using NanoString analysis.
Results: SEC-NR had an increased frequency of IL-17A-producing RORγt+CD4+ T cells compared to healthy controls before secukinumab treatment (P < 0.01). SEC-NR had a significant increase of CXCR3+ CD4+ T cells before secukinumab treatment compared to SEC-R (P < 0.01). Differentially expressed gene analysis revealed up-regulation of type 1 interferon (IFN)-regulated genes in SEC-NR patients compared to SEC-R patients after receiving the biologic. SEC-R patients had an up-regulated cytotoxic CD4+ T cell gene signature before receiving secukinumab treatment compared to SEC-NR patients.
Conclusion: The increased frequency of IL-17A-producing cells in SEC-NR patients suggests a larger inflammatory burden than SEC-R patients. With treatment, SEC-NR patients have a more pronounced type 1 IFN signature than SEC-R patients, suggesting a mechanism contributing to this larger inflammatory burden. The results point toward more immune heterogeneity in axSpA than has been recognized and highlights the need for precision therapeutics in this disease.

Objectives: To evaluate the concordance of results between the HORIZON-Pivotal Fracture Trial (PFT) and a non-randomized database study designed to emulate the trial.
Methods: HORIZON-PFT evaluated the efficacy of zoledronic acid vs placebo in reducing the risk of hip fractures and found a 41% risk reduction over a 3-year treatment period (HR = 0.59; 95% CI 0.42 to 0.83). Using two U.S. claims databases from 08/2007 to 12/2020 or 06/2021 we applied eligibility criteria from HORIZON-PFT and identified women with osteoporosis who initiated zoledronic acid or raloxifene as a proxy for placebo. The study protocol was registered on ClinicalTrials.gov (NCT04736693) before inferential analyses. We compared HORIZON-PFT and database study results using prespecified metrics.
Results: Due to low adherence in clinical practice, on-treatment follow up was truncated at 18 months in the database study. The hip fracture risk after 18 months was 9.3/1000 in the trial and 8.3/1000 in the database analysis. In the database study, zoledronic acid was associated with a 28% reduction in hip fractures risk compared to raloxifene (HR = 0.72; 95% CI 0.51 to 0.92). The attenuated effect of zoledronic acid in the database study may be explained by its shorter follow-up, as the interpolated estimate of the effect in HORIZON-PFT at 18 months was HRRCT 0.74, nearly identical to the observational estimate HRdatabase 0.72.
Conclusion: Real-world emulation of the HORIZON-PFT found that zoledronic acid reduced hip fractures risk over an 18-month follow-up period. Limited adherence in clinical practice diminished the magnitude of its preventive effect and precluded long-term estimation of effectiveness in this setting.

Objective: Mechanisms underlying the adolescent-onset and early-onset gout are unclear. This study aimed to discover variants associated with early-onset gout.
Methods: We conducted whole-genome sequencing in a discovery adolescent-onset gout cohort of 905 individuals (gout onset 12 to 19 years) to discover common and low-frequency single-nucleotide variants (SNVs) associated with gout. Candidate common SNVs were genotyped in an early-onset gout cohort of 2,834 individuals (gout onset ≤30 years old), and meta-analysis was performed with the discovery and replication cohorts to identify loci associated with early-onset gout. Transcriptome and epigenomic analyses, quantitative real-time polymerase chain reaction and RNA sequencing in human peripheral blood leukocytes, and knock-down experiments in human THP-1 macrophage cells investigated the regulation and function of candidate gene RCOR1.
Results: In addition to ABCG2, a urate transporter previously linked to pediatric-onset and early-onset gout, we identified two novel loci (Pmeta < 5.0 × 10-8): rs12887440 (RCOR1) and rs35213808 (FSTL5-MIR4454). Additionally, we found associations at ABCG2 and SLC22A12 that were driven by low-frequency SNVs. SNVs in RCOR1 were linked to elevated blood leukocyte messenger RNA levels. THP-1 macrophage culture studies revealed the potential of decreased RCOR1 to suppress gouty inflammation.
Conclusion: This is the first comprehensive genetic characterization of adolescent-onset gout. The identified risk loci of early-onset gout mediate inflammatory responsiveness to crystals that could mediate gouty arthritis. This study will contribute to risk prediction and therapeutic interventions to prevent adolescent-onset gout.

Objective: Systemic sclerosis (SSc) is a severe rheumatic disease causing fibrotic tissue rearrangement. Aberrant toll-like receptor (TLR) 8 transcripts in plasmacytoid dendritic cells (pDCs) were recently linked to SSc pathogenesis, which is at least partially mediated by increased type I interferon (IFN-I) responses. Here, we addressed the functional role of TLR8 signaling in different immune cell subsets of patients with SSc.
Methods: Monocytes, conventional dendritic cells (cDCs), and pDCs from the blood and skin of patients with SSc were analyzed for TLR8 protein expression. To assess TLR function, cytokine responses upon TLR7 and TLR8 stimulation were studied. To identify relevant alterations specific for patients with SSc (n = 16), patients with primary Sjögren disease (pSS; n = 10) and healthy controls (HCs; n = 13) were included into the study.
Results: In all individuals, TLR8 was expressed in monocytes and cDCs but not in pDCs. The TLR8 expression levels were overall similar in patients with SSc and pSS and HCs. Additionally, in all study participants, TLR8 stimulation of pDCs did not induce IFN-I expression. In contrast, monocytes from patients with SSc revealed increased interleukin (IL)-10 responses upon TLR8 (patients with SSc vs HCs, P = 0.0126) and TLR7/8 stimulation (patients with SSc vs HCs, P = 0.0170).
Conclusion: TLR8 protein is not expressed in pDCs of patients with SSc. Accordingly, they do not respond to TLR8 stimulation. In contrast, monocytes of patients with SSc respond to TLR8 stimulation with increased IL-10 responses. Therefore, TLR8 signaling in monocytes participates in SSc pathogenesis by conferring aberrant IL-10 expression.

Objective: We aimed to assess: 1. The frequency of axial spondyloarthritis (axSpA) according to extra-articular presentation and HLA-B27 status; 2. Clinical and imaging features that distinguish axSpA from non-axSpA; 3. The impact of MRI on diagnosis and classification of axSpA.
Methods: The Screening in Axial Spondyloarthritis in Psoriasis, Iritis, Colitis, (SASPIC) study enrolled patients in two multicenter cohorts. Consecutive patients with undiagnosed chronic back pain attending dermatology, ophthalmology, and gastroenterology clinics with PsO, AAU, or IBD, were referred to a local rheumatologist with special expertise in axSpA for a structured diagnostic evaluation. The primary outcome was proportion of patients diagnosed with axSpA by final global evaluation.
Results: Frequency of axSpA was 46.7%, 61.6%, and 46.8% in SASPIC-1 cases (n=212) and 23.5%, 57.9%, and 23.3% in SASPIC-2 cases (n=151) with PsO, AAU, or IBD, respectively. Among B27 positives, axSpA was diagnosed in 70%, 74.5%, and 66.7% in SASPIC-1, and in 71.4%, 87.8%, and 55.6% in SASPIC-2 in patients with PsO, AAU, or IBD, respectively. All musculoskeletal clinical features were non-discriminatory. MRI was indicative of axSpA in 60-80% of patients and MRI in all patients (SASPIC-2) versus on-demand (SASPIC-1) led to 25% fewer diagnoses of axSpA in HLA B27 negatives with PsO or IBD. Performance of the ASAS classification criteria was greater with routine MRI (SASPIC-2) though sensitivity was lower than previously reported.
Conclusions: Optimal management of patients presenting with PsO, AAU, IBD, and undiagnosed chronic back pain should include referral to a rheumatologist. Conducting MRI in all patients enhances diagnostic accuracy.

Objective: The study objective was to examine the disease, demographic, and imaging features associated with different inflammatory phenotypes of calcium pyrophosphate deposition (CPPD) disease, ie, recurrent acute calcium pyrophosphate (CPP) crystal arthritis, chronic CPP crystal inflammatory arthritis, and crowned dens syndrome (CDS).
Methods: Data from an international cohort (assembled from 25 sites in 7 countries for the development and validation of the 2023 CPPD classification criteria from the American College of Rheumatology/EULAR) that met the criteria were included. Three cross-sectional studies were conducted to determine the phenotypic characteristics of recurrent acute CPP crystal arthritis, chronic CPP crystal inflammatory arthritis, and CDS. Multivariable logistic regression analysis was used to calculate adjusted odds ratio (aOR) and 95% confidence interval (CI) to examine the association between potential risk factors and the inflammatory phenotype.
Results: Among the 618 people included (56% female; mean age [standard deviation] 74.0 [11.9] years), 602 (97.4%) had experienced acute CPP crystal arthritis, 332 (53.7%) had recurrent acute arthritis, 158 (25.6%) had persistent inflammatory arthritis, and 45 (7.3%) had had CDS. Recurrent acute CPP crystal arthritis associated with longer disease duration (aOR 2.88 [95% CI 2.00-4.14]). Chronic CPP crystal inflammatory arthritis was associated with acute wrist arthritis (aOR 2.92 [95% CI 1.81-4.73]), metacarpophalangeal joint osteoarthritis (aOR 1.87 [95% CI 1.17-2.97]), and scapho-trapezo-trapezoid (STT) joint osteoarthritis (aOR 1.83 [95% CI 1.15-2.91]), and it was negatively associated with either metabolic or familial risk for CPPD (aOR 0.60 [95% CI 0.37-0.96]). CDS was associated with male sex (aOR 2.35 [95% CI 1.21-4.59]), STT joint osteoarthritis (aOR 2.71 [95% CI 1.22-6.05]), and more joints affected with chondrocalcinosis (aOR 1.46 [95% CI 1.15-1.85]).
Conclusion: CPPD disease encompasses acute and chronic inflammatory phenotypes, each with specific clinical and imaging features that need to be considered in the diagnostic workup.
