RESUMEN
PURPOSE OF REVIEW: This review takes a look at the past, present, and future of SPARTAN, the Spondyloarthritis Research and Treatment Network, an organization of North American healthcare professionals dedicated to advancing research, education, and patient care in spondyloarthritis. RECENT FINDINGS: In 2022, SPARTAN completed the Classification of Axial SpondyloarthritiS Inception Cohort (CLASSIC) study, a collaboration with the Assessment in SpondyloArthritis International Society (ASAS). CLASSIC aimed to validate the 2009 ASAS classification criteria for axial spondyloarthritis. Other ongoing SPARTAN endeavors include the development of US referral recommendations for axial spondyloarthritis, an update of the 2019 ACR/SAA/SPARTAN treatment recommendations for axial spondyloarthritis and multiple educational initiatives. Twenty years after its inception, SPARTAN continues to grow and broaden its impact, guided by the SPARTAN vision of "a world free of spondyloarthritis through leadership in research and education."

OBJECTIVES: To examine the association of multimorbidity phenotypes at baseline with disease activity and functional status over time in ankylosing spondylitis (AS). METHODS: Patient-reported AS morbidities (comorbidities, N = 28 and extra-musculoskeletal manifestations, EMMs, N = 3) within 3 years of enrollment with a prevalence ≥1 %, were included from the Prospective Study of Outcomes in Ankylosing Spondylitis (PSOAS) cohort. We defined multimorbidity as ≥2 morbidities (MM2+) and substantial multimorbidity as ≥5 morbidities (MM5+). Multimorbidity clusters or phenotypes were identified using K-median clustering. Disease activity (ASDAS-CRP) and functional status (BASFI) measures were collected every 6 months. Generalized estimating equation method was used to examine the associations of multimorbidity counts and multimorbidity clusters with measures of disease activity and functional status over time. RESULTS: Among 1,270 AS patients (9,885 visits) with a median follow-up of 2.9 years (IQ range: 1.0-6.8 years), the prevalence of MM2+ and MM5+ was 49 % and 9 % respectively. We identified five multimorbidity clusters: depression (n = 321, 25 %), hypertension (n = 284, 22 %), uveitis (n = 274, 22 %), no morbidities (n = 238, 19 %), and miscellaneous (n = 153, 12 %). Patients in the depression cluster were more likely to be female and had significantly more morbidities and worse disease activity and functional status compared to those with no morbidities. CONCLUSION: Approximately 49 % of AS patients in the PSOAS cohort had multimorbidity and five distinct multimorbidity phenotypes were identified. In addition to the number of morbidities, the type of morbidity appears to be important to longitudinal outcomes in AS. The depression cluster was associated with worse disease activity and function.

INTRODUCTION: We studied the effect of intravenous (IV)-golimumab on fatigue and the association of fatigue improvement with clinical response post hoc in adults with active ankylosing spondylitis (AS) in the GO-ALIVE trial. METHODS: Patients were randomized to IV-golimumab 2 mg/kg (N = 105) at week (W) 0, W4, then every 8 W (Q8W) or placebo (N = 103) at W0, W4, W12, crossover to IV-golimumab 2 mg/kg at W16, W20, then Q8W through W52. Fatigue measures included Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) Question #1 (fatigue; 0 [none], 10 [worst]; decrease indicates improvement) and 36-Item Short Form Health Survey (SF-36) vitality subscale (0 [worst], 100 [best]; increase indicates improvement). Minimum clinically important difference is ≥ 1 for BASDAI-fatigue and ≥ 5 for SF-36 vitality. GO-ALIVE primary endpoint was Assessment of SpondyloArthritis international Society ≥ 20% improvement criteria (ASAS20). Other clinical outcomes assessed included other ASAS responses, Ankylosing Spondylitis Disease Activity Score, and Bath Ankylosing Spondylitis Functional Index score. The distribution-based minimally important differences (MIDs) were determined for BASDAI-fatigue and SF-36 vitality. The relationship between improvement in fatigue and clinical outcomes was assessed via multivariable logistic regression. RESULTS: Mean changes in BASDAI-fatigue/SF-36 vitality scores were greater with IV-golimumab versus placebo at W16 (- 2.74/8.46 versus - 0.73/2.08, both nominal p ≤ 0.003); by W52 (after crossover), differences between groups narrowed (- 3.18/9.39 versus - 3.07/9.17). BASDAI-fatigue/SF-36 vitality MIDs were achieved by greater proportions of IV-golimumab-treated versus placebo-treated patients at W16 (75.2%/71.4% versus 42.7%/35.0%). A one-point/five-point improvement in BASDAI-fatigue/SF-36 vitality scores at W16 increased likelihood of achieving ASAS20 (odds ratios [95% confidence intervals]: 3.15 [2.21, 4.50] and 2.10 [1.62, 2.71], respectively) and ASAS40 (3.04 [2.15, 4.28] and 2.24 [1.68, 3.00], respectively) responses at W16; concurrent improvements and clinical response at W52 were consistent. A one-point/five-point improvement in BASDAI-fatigue/SF-36 vitality scores at W16 predicted increased likelihood of achieving ASAS20 (1.62 [1.35, 1.95] and 1.52 [1.25, 1.86], respectively) and ASAS40 (1.62 [1.37, 1.92] and 1.44 [1.20, 1.73], respectively) responses at W52. CONCLUSIONS: IV-golimumab provided important and sustained fatigue improvement in patients with AS that positively associated with achieving clinical response. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT02186873.
Ankylosing spondylitis (AS) is a type of arthritis that mostly affects the spine. Patients with AS also often have severe fatigue. Intravenous (IV)-golimumab, which blocks the inflammatory action of tumor necrosis factor, is approved to treat AS. We used information from a clinical trial (GO-ALIVE) to determine whether IV-golimumab reduced fatigue in patients with AS, and if fatigue improvement was associated with improvement in other AS symptoms, including spinal pain, ability to function, and inflammation. In the 1-year GO-ALIVE study, patients were assigned to receive either IV-golimumab or placebo. Patients assigned to placebo were switched to IV-golimumab starting at week 16. The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) fatigue question and the 36-Item Short Form Health Survey (SF-36) vitality subscale were used to assess fatigue. Improvement in AS symptoms was measured using the Assessment of SpondyloArthritis international Society ≥ 20% and ≥ 40% improvement criteria (ASAS20 and ASAS40). After 16 weeks of treatment, patients treated with IV-golimumab, on average, had statistically significantly greater improvement in both measures of fatigue than patients treated with placebo. At 1 year, after the placebo group had received IV-golimumab starting at week 16, improvement in fatigue was similar between groups. Improvement in fatigue at week 16 increased the likelihood that ASAS20 and ASAS40 would be achieved at week 16. Similar results were observed at 1 year. Additionally, improvement in fatigue at week 16 predicted the likelihood of achieving ASAS20 and ASAS40 at 1 year. Together, these results demonstrate that IV-golimumab provided important, long-term improvement in fatigue in patients with AS that was positively associated with improvement in AS symptoms.
RESUMEN
OBJECTIVE: To evaluate the association between the Systemic Lupus International Collaborating Clinics frailty index (SLICC-FI) and damage accrual in systemic lupus erythematosus (SLE) patients. METHODS: Patients from the multiethnic, multicenter LUpus in MInorities, NAture versus nurture (LUMINA) cohort were included. Damage was ascertained with the SLICC/American College of Rheumatology Damage Index (SDI) at last visit (range 0-51). The first visit in which the SLICC-FI score could be derived was considered as the baseline (range 0-1). Univariable and multivariable negative binomial regression models were performed to determine the association between the baseline SLICC-FI score (per 0.05 increase) and the change in the SDI score (difference between last and baseline SDI score), adjusted for sex, age at diagnosis, ethnicity, insurance, prednisone daily dose, and antimalarial and immunosuppressive drug use at baseline. Age and sex were included a priori in the multivariable model; the other variables were included if they reached P < 0.10 in the univariable models. RESULTS: Of the 503 patients included, 454 (90.3%) were female, with a mean ± SD age of 37.1 ± 12.5 years at diagnosis. The mean ± SD baseline SLICC-FI score was 0.26 ± 0.06. The mean ± SD baseline SDI score was 0.6 ± 1.0, and the mean ± SD change in the SDI score was 1.9 ± 2.2. Higher SLICC-FI scores at baseline (per 0.05 increase) were associated with greater damage accrual in the multivariable model after adjustment for possible confounders (incidence rate ratio 1.20 [95% confidence interval 1.08-1.33], P = 0.0015). CONCLUSION: The SLICC-FI is associated with damage accrual in SLE patients from a multiethnic cohort, supporting the importance of this index in the evaluation of SLE patients, combining several aspects of their disease.

OBJECTIVE: The long-term impact of childhood-onset systemic lupus erythematosus (SLE) on health-related quality of life (HRQoL) in adult SLE patients in comparison to those with adult-onset SLE is unknown. We aim to examine and compare HRQoL trajectories in adults with adolescent- and adult-onset SLE. METHODS: Patients enrolled in the LUpus in MInorities: NAture versus Nurture cohort were included. Adolescent-onset SLE were those diagnosed before 24 years of age, and adult-onset SLE were those diagnosed otherwise. Sociodemographic, clinical, medications, behavioral/psychological, and functioning data were obtained. Longitudinal trajectories of the physical component summary (PCS) and the mental component summary (MCS) Short Form 36 health survey scores were compared between the groups using a linear mixed model accounting for time-dependent and independent covariates. RESULTS: A total of 470 SLE patients were included (95 with adolescent-onset SLE and 375 with adult-onset SLE). The mean ± SD age at diagnosis was 19.7 ± 2.8 years in the adolescent group and 39.3 ± 11.0 years in the adult group. The baseline PCS scores were higher (better physical functioning) in adolescent-onset SLE than in adult-onset SLE (38.9 versus 34.3, respectively; P < 0.001); however, the baseline MCS scores were comparable between the groups (41.4 versus 40.5, respectively; P = 0.53). The HRQoL improved equally in both groups with no statistically significant difference within and between the groups (last mean PCS and MCS scores 43.9 and 45.3 in adolescent-onset SLE; 38.1 and 43 in adult-onset SLE). CONCLUSIONS: Adults with adolescent-onset SLE exhibited better physical functioning than those in the adult SLE group, despite more severe disease; noteworthy, HRQoL was below the general US population, despite clinically meaningful improvement in HRQoL over time in both groups.

OBJECTIVE: Sacroiliac (SI) joint and spinal inflammation are characteristic of ankylosing spondylitis (AS), but some patients with AS have been identified who have discordant radiographic disease. We studied an AS subgroup with long-standing disease and fused SI joints. We identified factors associated with discrepant degrees of radiographic damage between the SI joints and spine. METHODS: From the Prospective Study of Outcomes in AS (PSOAS) cohort, patients with a disease duration ≥ 20 years and fused SI joints were included in a nested case-control design. Patients with and without syndesmophytes were used as cases and controls for analysis. We used classification and regression tree (CART) analysis to determine risk factors for syndesmophytes presence and reexamined the validity of the risk factors using univariable logistic regression models. RESULTS: There were 354 patients in the subgroup, 23 of whom lacked syndesmophytes. CART analysis showed females were less likely to have syndesmophytes. The next important predictor was age of symptom onset in males, with age of onset ≤ 16 years being less likely to have syndesmophytes. Univariable analysis confirmed females were less likely to have syndesmophytes (odds ratio [OR] 0.17, 95% CI 0.07-0.41). Syndesmophyte presence was associated with HLA-B27 positivity (P = 0.03) and age of symptom onset > 16 years old (OR 2.72, 95% CI 1.15-6.45). All 23 patients who lacked syndesmophytes were HLA-B27 positive. CONCLUSION: Using CART analysis and univariable modeling, women were less likely to have syndesmophytes despite advanced disease duration and SI joint disease. Patients with younger age of symptom onset were less likely to have syndesmophytes. All patients without syndesmophytes were HLA-B27 positive, indicating HLA-B27 positivity may be more associated with SI disease than spinal disease.

OBJECTIVES: Spondyloarthritis (SpA) results from the interplay between genetic and environmental factors. An emerging modifiable factor is the human intestinal microbiota, which multiple studies in children and adults have shown to be abnormal in SpA patients, including enthesitis related arthritis and ankylosing spondylitis (AS). However, HLA-B27 itself appears to impact the contents of the microbiota and is more common in SpA patients versus controls, thus serving as a confounding factor in most comparative studies. METHODS: This was a cross-sectional study that evaluated the contents of the faecal microbiota among 29 patients with HLA-B27+ AS and 43 healthy adults who underwent 16S sequencing and genotyping as part of the TwinsUK Programme. RESULTS: HLA-B27 positive+ patients and healthy controls demonstrated substantial clustering based upon diagnosis. Decreased richness was observed among the AS patients, although measures of evenness were similar. After correction for multiple comparisons, several taxa - including Faecalibacterium prausnitzii and Coprococcus - were elevated in AS patients compared to controls, even when restricted to female subjects, while Bacteroides fragilis, Ruminococcus, and Akkermansia muciniphila were depleted in AS patients. CONCLUSIONS: Consistent with some previous studies, our study demonstrates in patients with AS associations with Coprococcus, Bacteroides, and Ruminococcus. Other findings, including increased Faecalibacterium, are inconsistent with previous studies and thus potentially underscore the necessity of evaluating HLA-B27 positive controls in studies evaluating the impact of the intestinal microbiota on SpA.

RESUMEN
OBJECTIVE: This study examined the safety and efficacy of biological agents, especially tumour necrosis factor (TNF) inhibitors, for HIV-positive rheumatology patients refractory to standard therapy. METHODS: This study is a retrospective case series including patients derived from a community HIV clinic as well as from two academic centres. Initial visit data collected included: sociodemographic characteristics, CD4 counts, HIV viral load and medication use. Patients with persistent disease activity despite standard conservative therapy were begun on biological agents.The main outcomes were patient and physician global assessment of treatment response and medication side effects in patients with rheumatological disorders treated with biological medications over time. RESULTS: Seventeen patients were seen from 2003 to 2021, including eight from our previous cohort published in 2008 and nine seen since then, five of whom taking TNF blockers for more than 10 years. Three (17.7%) had rheumatoid arthritis, five (29.4%) psoriatic arthritis, four (23.5%) axial spondyloarthritis and the rest (29.4%) peripheral spondyloarthritis. Antiretroviral therapy had been used in 15. All but one had at least a partial response to biological therapy. There were no major infectious episodes necessitating the discontinuation of medications with only one patient discontinuing treatment due to rising HIV viral load. Patients not on antiretroviral therapy reported no adverse side effects from biological therapy. Four patients were switched to ustekinumab, secukinumab, tocilizumab or upadacitinib from anti-TNF therapy without complications. CONCLUSIONS: These data suggest that biological therapy, especially anti-TNF agents are safe and well tolerated in HIV positive individuals even over several years.

OBJECTIVE: The impact of the COVID-19 pandemic on patients with inflammatory rheumatic diseases, such as ankylosing spondylitis (AS), has been variable. Here, we assess disease activity and health-related quality of life (HRQoL) through the pandemic in patients with AS. METHODS: In the open-label extension (OLE) of the phase 2b BE AGILE study, patients with AS received 160 mg of subcutaneous bimekizumab every 4 weeks. We assessed Ankylosing Spondylitis Disease Activity Score with C-reactive protein (ASDAS-CRP), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Ankylosing Spondylitis Quality of Life (ASQoL) scores in the OLE immediately before and during the COVID-19 pandemic (September 2019 to April 2021). RESULTS: A total of 232 patients remained in the BE AGILE OLE and were included in this post hoc study at the start of the analysis period (September 1, 2019); 12 patients had a COVID-19 treatment-emergent adverse event, and no cases resulted in death. The number of missed bimekizumab doses due to COVID-19 (11 doses) was minimal, and missed assessments remained low (≤5%) compared with the prepandemic period. Mean ASDAS-CRP (1.8), BASDAI (2.4), and ASQoL scores (2.8) in the OLE were low at pre-pandemic baseline and remained stable at 1.7 to 1.8, 2.2 to 2.4, and 2.0 to 2.8, respectively, across successive 3-month periods immediately before and during the pandemic. ASDAS-CRP, BASDAI, and ASQoL stability was consistent across major study countries. CONCLUSION: Disease activity and HRQoL remained stable during the COVID-19 pandemic in patients with AS receiving bimekizumab in the BE AGILE OLE, with no indication of negative effects on these outcomes.

BACKGROUND/OBJECTIVE: This post hoc analysis assessed efficacy and safety of intravenous (IV) golimumab in ankylosing spondylitis (AS) patients with early disease (ED) versus late disease (LD). METHODS: The phase 3, double-blind, GO-ALIVE study randomized patients to IV golimumab 2 mg/kg at weeks 0 and 4 and then every 8 weeks through week 52, or placebo at weeks 0, 4, and 12 with crossover to IV golimumab at week 16. Clinical efficacy was assessed by ≥20% improvement in Assessment of Spondyloarthritis International Society response criteria (ASAS20), ≥50% improvement in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI 50), and Ankylosing Spondylitis Disease Activity Score (ASDAS) <1.3 (inactive disease). Using self-reported duration of inflammatory back pain (IBP), patients were grouped into quartiles: first = ED and fourth = LD. Descriptive statistics summarized efficacy and safety findings through 1 year. RESULTS: Early disease patients (n = 60) were ~10 years younger and had shorter median AS (IBP) symptom duration (2-3 years) versus LD patients (n = 52; 21-24 years). At week 16, numerically higher proportions of golimumab- than placebo-treated patients achieved ASAS20 (ED: 71% vs. 32%; LD: 67% vs. 21%), BASDAI 50 (ED: 40% vs. 12%; LD: 33% vs. 7%), and ASDAS <1.3 (ED: 17% vs. 4%; LD 8% vs. 0%) regardless of IBP duration. Efficacy was durable through 1 year of treatment; however, response rates were numerically higher in patients with ED versus LD. Through week 60, adverse events and serious adverse events, respectively, were reported by 46% and 3% of ED patients and 61% and 2% of LD patients. CONCLUSION: Prompt diagnosis of AS and early treatment with IV golimumab may yield more robust improvements in disease activity.

Multiple studies have shown the microbiota to be abnormal in patients with spondyloarthritis (SpA). The purpose of this study was to explore the genetic contributions of these microbiota abnormalities. We analyzed the impact of HLA-B27 on the microbiota of children at risk for SpA and compared the microbiota of HLA-B27+ pediatric offspring of ankylosing spondylitis (AS) patients with that of HLA-B27+ children with SpA. Human DNA was obtained from the offspring for determination of HLA-B27 status and polygenic risk score (PRS). Fecal specimens were collected from both groups for sequencing of the V4 region of the 16S ribosomal RNA gene. Among the offspring of AS patients, there was slight clustering by HLA-B27 status. After adjusting for multiple comparisons, five operational taxonomic units (OTUs) representing three unique taxa distinguished the HLA-B27+ from negative children: Blautia and Coprococcus were lower in the HLA-B27+ offspring, while Faecalibacterium prausnitzii was higher. HLA-B27+ offspring without arthritis were compared to children with treatment-naïve HLA-B27+ SpA. After adjustments, clustering by diagnosis was present. A total of 21 OTUs were significantly associated with diagnosis state, including Bacteroides (higher in SpA patients) and F. prausnitzii (higher in controls). Thus, our data confirmed associations with B. fragilis and F. prausnitzii with juvenile SpA, and also suggest that the mechanism by which HLA-B27 is associated with SpA may not involve alterations of the microbiota.
RESUMEN
Chronic inflammatory back pain (CIBP) occurs in up to one-third of those with chronic back pain. Criteria for diagnosis of inflammatory back pain include an onset below 50 years. Using the US National Health and Nutrition Examination Survey data for 2009-2010, we showed that 3% of adults aged 50-69 years have features of CIBP with onset on or after 50 years. There is little information in the literature on CIBP of late onset. Patients with late onset CIBP may be falling through the cracks.

The spectrum of axial spondyloarthritis (AxSpA) (including both non-radiographic and radiographic AxSpA), also known as ankylosing spondylitis AS, has achieved growing recognition. With the development of treatments not only effective in controlling disease activity but also in slowing radiographic progression, and given the cost and risk profiles of these novel treatments and the limitations of current clinical criteria, imaging and peripheral blood biomarkers (C-reactive protein, HLA-B27 testing), the need for better biomarkers has never been greater. The purpose of this review is to present up-to-date information on the biomarkers for the diagnosis for assessing disease diagnosis, activity, treatment response, and radiographic progression of AxSpA, and entails multiple search strings used to identify articles of interest published in PubMed and the Cochrane database up to May 1, 2021. We present the current status of research in serologic biomarkers such as cytokines, adipokines, matrix metalloproteinases, calprotectin, CD74, antibodies, bone turnover markers, and circulating protein fragments of cartilage and connective tissue degradation and other biomarkers. Despite a great deal of work, most serologic results have been disappointing and to date none perform better than CRP. Recent promising preliminary data for some has been published, but require further confirmation. Transcriptomic biomarkers such as micro-RNAs and genetic biomarkers also show promise to assist in diagnosis and possibly for radiographic severity, including a recently developed panel of genetic risk markers used in a polygenic risk score instrument in AS diagnosis. These need further confirmation and application in AS as well as in nr-AxSpA.

OBJECTIVE: To evaluate the long-term effect of ixekizumab (IXE) on radiographic changes in the spine in patients with radiographic axial spondyloarthritis (r-axSpA) by measuring change from baseline through 2 years in modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS), and to identify potential predictors of progression. METHODS: This study evaluates patients from COAST-V (ClinicalTrials.gov: NCT02696785, biologic disease-modifying antirheumatic drug-naïve) and COAST-W (NCT02696798, tumor necrosis factor inhibitor-experienced) who had mSASSS data at baseline in the originating studies and 108 weeks after baseline in the extension study COAST-Y (NCT03129100). We examined the proportion of patients who did not have spinal radiographic progression through 2 years (108 weeks) of treatment with IXE (80 mg every 2 or 4 weeks) and the change from baseline to year 2 in mSASSS. Potential predictors of spinal radiographic progression were also evaluated. RESULTS: Among patients with evaluable radiographs who were originally assigned to IXE (n = 230), mean (SD) change in mSASSS from baseline at year 2 was 0.3 (1.8). The proportion of nonprogressors over 2 years was 89.6% if defined as mSASSS change from baseline < 2 and 75.7% if defined as mSASSS change from baseline ≤ 0. Predictors of structural progression at year 2 (mSASSS change > 0) were age ≥ 40, baseline syndesmophytes, HLA-B27 positivity, and male sex. Week 52 inflammation in Spondyloarthritis Research Consortium of Canada spine was also a predictor of radiographic progression at year 2 in patients with magnetic resonance imaging data in COAST-V (n = 109). CONCLUSION: The majority of patients with r-axSpA receiving IXE had no radiographic progression in the spine through 2 years of treatment. Predictors were generally consistent with previous studies.

OBJECTIVE: Individuals with ankylosing spondylitis (AS) have a greater cardiovascular (CV) risk than those in the general population. The effect of tumor necrosis factor inhibitors (TNFis) on CV risk, including on the development of hypertension (HTN), remains unclear, with some data suggesting higher risk. We assessed the association of TNFi use with incident HTN in a longitudinal AS cohort. METHODS: Adults with AS enrolled in a prospective cohort in 2002-2018 were examined every 4-6 months. TNFi use during the preceding 6 months was ascertained at each study visit. We defined HTN by patient-reported HTN, antihypertensive medication use, or, on 2 consecutive visits, systolic blood pressure (BP) ≥ 140 mmHg or diastolic BP ≥ 90 mmHg. We evaluated the association between TNFi use and the development of HTN with marginal structural models, estimated by inverse probability-of-treatment weighting, to account for time-dependent confounders and informative censoring. Potential confounders included age, sex, race, site, nonsteroidal antiinflammatory drug use, and disease activity. RESULTS: We included 630 patients without baseline HTN and with at least 1 year of follow-up. Of these, 72% were male, mean age was 39 ± 13 years, and 43% used TNFi at baseline. On follow-up (median 5 yrs), 129 developed incident HTN and 163 started on TNFi during follow-up. TNFi use was not associated with incident HTN (adjusted HR 1.10, 95% CI 0.83-1.37). CONCLUSION: In our prospective AS cohort, TNFi use was not significantly associated with incident HTN.
