PATH-04. TRANSFORMATION OF GRADE 2 OLIGODENDROGLIOMA TO GLIOSARCOMA WITH RAPID AND EXTENSIVE PROGRESSION: CASE REPORT.

Abstract Transition of WHO grade 2 oligodendroglioma to gliosarcoma is rare. We report a case of a 40 year-old gentleman with WHO grade 2 oligodendroglioma, isocitrate dehydrogenase enzyme (IDH)-mutant, 1p/19q co-deletion positive, O6-methylguanine-DNA methyltransferase (MGMT) promoter methylated, tumor mutational burden of 5 mutations/megabase, with microsatellite stability. He underwent rapid and extensive transformation to WHO grade 4 glioblastoma with gliosarcomatous features, mesenchymal subclass on DNA methylation, IDH-wild type, 1p/19q co-deletion negative, MGMT promoter methylated. He was diagnosed with bi-hemispheric multifocal partially enhancing, T2-FLAIR hyperintense lesions. Pathology revealed WHO grade 2 oligodendroglioma. He enrolled on a clinical trial to receive proton radiation (45 Gray in 25 fractions) to the involved tumor sites. Three weeks after initiation of radiation, he developed headache, imbalance, and confusion. MRI brain 3 weeks after completion of radiation revealed worsening enhancement, edema, and a new region of non-enhancing T2-FLAIR hyperintensity. Bevacizumab was added for presumed pseudo-progression; followed by chemotherapy with procarbazine and lomustine (PC). Four cycles of PC were completed with observations of gradual clinical and radiographic worsening after each cycle. Re-resection of multifocal tumor for tissue diagnosis and tumor debulking revealed progression to WHO grade 3 oligodendroglioma with high mitotic activity and regions of palisading necrosis. Two weeks postoperatively, malignant cerebral edema developed, requiring left sided decompressive craniectomy. Despite early introduction of 2nd-line chemotherapy with temozolomide, his disease continued to progress and he succumbed 1.5 years after initial diagnosis. Autopsy revealed extensive bi-hemispheric involvement of WHO grade 4 glioblastoma. Our patient demonstrated unusually rapid clinical and radiographic progression within one month after completion of radiation. Other reported cases in the literature have documented progression at 1 to 5 years after initial treatment. Both IDH mutation and 1p19q co-deletion were lost in the gliosarcomatous transformation. This tumor did not respond to alkylating agents despite the MGMT promoter-methylated status.

Prevention of Radiographic Progression in Higher-Risk Patients with Rheumatoid Arthritis Using Filgotinib in PhaseIII Studies: Narrative Review of PostHoc Analyses.

Filgotinib is an oral preferential Janus kinase1 inhibitor that demonstrated significant reductions in radiographic progression, with an acceptable tolerability and safety profile, vs placebo in patients with rheumatoid arthritis (RA) and an inadequate response to methotrexate (MTX-IR; FINCH1) and vs MTX in MTX-naïve patients with RA (FINCH3). International treatment guidelines identify multiple poor prognostic factors (PPFs) associated with worse disease outcomes among patients with RA. However, questions remain both about the clinical utility of considering PPFs and about which PPFs should drive treatment decisions. Additionally, the role of radiographic findings in clinical practice continues to be discussed and to evolve. This review examines radiographic results from posthoc analyses of phase3 trials of filgotinib that examined subgroups with 4PPFs or with baseline estimated rapid radiographic progression (e-RRP). In MTX groups, there were trends toward greater progression among patients with 4PPFs or e-RRP, suggesting these subgroups may comprise a higher-risk population. Results show general consistency for the efficacy of filgotinib 200mg plus MTX vs placebo plus MTX/MTX monotherapy on radiographic assessments, including change from baseline in modified total Sharp score and proportions without radiographic progression, even among MTX-IR or MTX-naïve patients with 4PPFs or e-RRP who may be at higher risk of bone damage. Multivariate analysis identified multiple factors associated with baseline e-RRP status. This summary of the current understanding of benefits associated with filgotinib on radiographic progression and the relevance of baseline factors to these benefits may help inform treatment decisions for patients facing high risk of radiographic progression.

Benefit of Filgotinib, a JAK1 Preferential Inhibitor, in Rheumatoid Arthritis Patients with Previous Rapid Radiographic Progression: Post Hoc Analysis of Two Trials.

We conducted a post hoc analysis of efficacy and safety of filgotinib stratified by estimated radiographic progression rate before baseline (BL) in patients with rheumatoid arthritis (RA) who had inadequate response to methotrexate (MTX; FINCH 1; NCT02889796) or were naïve to it (FINCH 3; NCT02886728). Radiographic progression rate was BL-Modified Total Sharp Score (mTSS) divided by RA duration (BL mTSS/year); estimated rapid radiographic progression (e-RRP) was BL change in mTSS/year ≥ 5; and estimated nonrapid radiographic progression (e-NRRP) was BL mTSS/year < 5. Efficacy and safety were compared between subgroups. All p-values are nominal. In FINCH 1 and FINCH 3, 558/1755 (31.8%) and 787/1249 (63.0%) patients, respectively, had BL e-RRP. BL characteristics were generally similar between subgroups within each trial. At week (W) 24, in FINCH 1, proportions achieving a Disease Activity Score 28 for rheumatoid arthritis with C-reactive protein < 2.6 were significantly greater with filgotinib 200 (FIL200) and 100mg (FIL100) versus placebo among e-RRP and e-NRRP subgroups. In each study, proportions of FIL-treated patients achieving Clinical Disease Activity Index ≤ 2.8 and Simple Disease Activity Index ≤ 3.3 were similar between subgroups. In FINCH 3, disease activity measures were at least numerically improved among patients receiving FIL versus MTX monotherapy. At W24, mTSS changes from BL (CFB) were greater among patients with e-RRP in FINCH 1 and FINCH 3 versus e-NRRP (0.81 versus 0.19, p = 0.001; 0.67 versus 0.25, p = 0.31, respectively). At W52, in FINCH 1, mTSS CFBs were smaller among e-RRP patients treated with FIL200 (0.40; p < 0.001) and FIL100 (0.77; p = 0.024) versus adalimumab (ADA; 1.46). In FINCH 3 at W52, mTSS CFBs were significantly smaller with FIL200 versus MTX among e-RRP patients. Rates of treatment-emergent adverse events (AEs) were comparable between subgroups and across treatment arms. Patients with previous e-RRP who received standard care tended to progress radiographically. FIL200 demonstrated persistent, consistent benefit for disease activity control among e-RRP and e-NRRP subgroups, and AE profiles were similar between subgroups. Although filgotinib efficacy was somewhat reduced among patients with e-RRP, filgotinib treatment slowed radiographic progression in both subgroups. Clinicaltrials.gov NCT02889796, NCT02886728.

Clinical characteristics and variants that predict prognosis of difficult-to-treat rheumatoid arthritis.

Factors influencing prognosis after administration of the last biologic or targeted synthetic disease-modifying antirheumatic drug (b/tsDMARD) to patients with difficult-to-treat rheumatoid arthritis (D2T_RA) were evaluated in a clinical setting. RA patients who met the EULAR definition of D2T_RA were recruited. These patients were grouped according to success/failure. Success was defined as sustained within light disease activity or discontinued after clinical remission, and all of the following were met, including glucocorticoid (GCS) < 7.5mg/day, no rapid radiographic progression, and improved quality of life from the beginning of the b/tsDMARD (baseline). Failure was defined as any other condition from success. The primary endpoint of the study was success or failure at 12months after baseline. Factors influencing success/failure were statistically evaluated. A total of 71 D2T_RA patients were selected, 22 were in the success group and 49 in the failure group. For patients taking GCS and methotrexate (MTX) ≤ 8.6mg/week, only one was included in the success group and the other 24 were included in the failure group (p < 0.001). Of the 18 patients without GCS and with MTX ≥ 8.7mg, 12 patients whose 28-joint disease activity score ≤ 1.90 at 3months or ≤ 2.54 at 6months were in the success group (p < 0.01). D2T_RA patients with GCS or MTX ≤ 8.6mg at baseline are considered to be at high risk of repeat D2T_RA. Patients with no GCS and MTX ≥ 8.7mg are more likely to withdraw from D2T_RA if their disease activity is tightly controlled.

Assessing the risk of rapid radiographic progression in Hungarian rheumatoid arthritis patients

BackgroundThe outcome of rheumatoid arthritis (RA) should be determined early. Rapid radiological progression (RRP) is > or = 5 units increase according to the van der Heijde-Sharp score within a year. The risk of RRP can be estimated by a matrix model using non-radiographic indicators, such as C-reactive protein (CRP), rheumatoid factor (RF) and swollen joint count (SJC).Patients and methodsA non-interventional, cross-sectional, retrospective study was conducted in eleven Hungarian arthritis centres. We assessed RRP risk in biologic-naïve RA patients with the prevalence of high RRP risk as primary endpoint. RRP was calculated according to this matrix model. As a secondary endpoint, we compared RRP in methotrexate (MTX) responders vs non-responders.ResultsWe analyzed data from 1356 patients. Mean CRP was 17.7 mg/l, RF was 139.3 IU/ml, mean 28-joint disease activity score (DAS28) was 5.00 and mean SJC was 6.56. Altogether 18.2% of patients had high risk (≥40%) of RRP. RA patients with high RRP risk of RRP (n = 247) had significantly lower age compared to those with RRP < 40% (n = 1109). MTX non-response (OR: 16.84), male gender (OR: 1.67), erosions at baseline (OR: 1.50) and ACPA seropositivity (OR: 2.18) were independent predictors of high-risk RRP. Male gender (OR: 5.20), ACPA seropositivity (OR: 4.67) and erosions (OR: 7.98) were independent predictors of high RRP risk in MTX responders.ConclusionsIn this Hungarian study, high RRP risk occurred in 18% of RA patients. These patients differ from others in various parameters. RRP was associated with non-response to MTX.

Modified Disease Activity Score at 3 Months Is a Significant Predictor for Rapid Radiographic Progression at 12 Months Compared With Other Measures in Patients With Rheumatoid Arthritis.

ObjectiveProgressive rheumatoid arthritis (RA) is responsible for joint damage causing disabilities, but there is no agreement on which disease measures best predict radiographic progression. We aimed to determine which disease activity measures, including the disease activity score, the modified disease activity score in 28 joints with C‐reactive protein testing (M‐DAS28‐CRP), the Clinical Disease Activity Index, and the Health Assessment Questionnaire Disability Index, at baseline and 3 months best predicted rapid radiographic progression (RRP) in patients with early RA.MethodsData were used from PREMIER, a 2‐year, multicenter, double‐blind, active comparator controlled study with methotrexate (MTX)–naïve patients with RA and active disease for less than 3 years. Treatments included adalimumab plus oral MTX, adalimumab, or oral MTX. Only patients in the MTX arm were analyzed in this study. RRP was defined as a change in the modified total Sharp score of less than 3.5 at month 12. The logistic regression analysis assessed the impact of measures at baseline and 3 months on RRP at 12 months. Best cutoff points of the M‐DAS28‐CRP were also estimated by using area under the receiver operating characteristic curve.ResultsA total of 149 patients were included (female patients: n = 113 [75.8%]; positive rheumatoid factor: n = 127 [85.2%]; mean [SD] age: 52.9 [13.3] years; mean [SD] disease duration: 0.8 [0.9] year; mean [SD] M‐DAS28‐CRP: 6.3 [0.9]). After adjusting for potential confounders, only the M‐DAS28‐CRP at baseline (adjusted odds ratio [AOR] = 3.29; 95% confidence interval [CI]: 1.70‐6.36) and 3 months (AOR = 2.56; 95% CI: 1.43‐4.56) strongly predicted RRP at 12 months. M‐DAS28‐CRP of 4.5 and 2.6 at baseline and 3 months, respectively, maximized positive and negative predictive values for prediction of RRP.ConclusionThe M‐DAS28‐CRP was a stronger predictor at baseline and 3 months for RRP compared with other disease activity measures. Removing tender joint count and patient global assessment from the DAS28‐CRP improves prediction of RRP.

An updated matrix to predict rapid radiographic progression of early rheumatoid arthritis patients: pooled analyses from several databases.

In early RA, some patients exhibit rapid radiographic progression (RRP) after one year, associated with poor functional prognosis. Matrices predicting this risk have been proposed, lacking precision or inadequately calibrated. We developed a matrix to predict RRP with high precision and adequate calibration. Post-hoc analysis by pooling individual data from cohorts (ESPOIR and Leuven cohorts) and clinical trials (ASPIRE, BeSt and SWEFOT trials). Adult DMARD-naïve patients with active early RA for which the first therapeutic strategy after inclusion was to prescribe methotrexate or leflunomide were included. A logistic regression model to predict RRP was built. The best model was selected by 10-fold stratified cross-validation by maximizing the Area Under the Curve. Calibration and discriminatory power of the model were checked. The probabilities of RRP for each combination of levels of baseline characteristics were estimated. 1306 patients were pooled. 20.6% exhibited RRP. Four predictors were retained: rheumatoid factor positivity, presence of at least one RA erosion on X-rays, CRP > 30mg/l, number of swollen joints. The matrix estimates RRP probability for 36 combinations of level of baseline characteristics with a greatly enhanced precision compared with previously published matrices (95% CI: from ± 0.02 minimum to ± 0.08 maximum) and model calibration is excellent (P = 0.79). A matrix proposing RRP probability with high precision and excellent calibration in early RA was built. Although the matrix has moderate sensitivity and specificity, it is easily usable and may help physicians and patients to make treatment decisions in daily clinical practice.

Association of cumulative anti-cyclic citrullinated protein antibodies with radiographic progression in patients with rheumatoid arthritis.

Antibody against cyclic citrullinated protein (ACPA) is counted as one of the most important biomarkers in diagnosis, classification, and prognosis of rheumatoid arthritis (RA). We examined the evolution of ACPA during disease course and assess predictive value of time-weighted cumulative ACPA titer on radiographic progression in RA patients. A group of 734 patients with RA was followed longitudinally over 2years, with annual measurements of ACPA. The cumulative titers of ACPA were calculated using the trapezoidal rule and were divided into three categories: negative, low-to-moderate, and high. Radiographs of the hands were scored with the modified Sharp score (SHS). Multivariable logistic regression models were performed to identify independent predictors over follow-up for individual patients with different combinations of risk factors. The effect size was computed by Cohen's d method. The patients with radiographic progression had a higher SHS at baseline; and smoking status, diabetes, RF positivity, and use of biologic DMARDs were independently associated with radiographic progression (all P < 0.05). As for ACPA, reversion happened more commonly in men and was associated with younger onset age and lower titer at baseline, but it had no direct relevance to radiographic outcome. In multivariable regression analysis, only high cumulative or baseline titer of ACPA had a predictive power for rapid radiographic progression (all P < 0.05), and cumulative ACPA titer was superior in terms of statistical significance (Cohen's d, 0.637 versus 0.583). High cumulative ACPA titer was independently associated with accelerated radiographic progression, especially with initiation of joint damage.

Distinct Urinary Metabolic Profile in Rheumatoid Arthritis Patients: A Possible Link between Diet and Arthritis Phenotype

Objective. We undertook this study to investigate the discriminant metabolites in urine from patients with established rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and from healthy individuals. Methods. Urine samples were collected from 148 RA patients, 41 SLE patients and 104 healthy participants. The urinary metabolomic profiles were assessed using 1H nuclear magnetic resonance spectroscopy. The relationships between discriminant metabolites and clinical variables were assessed. Collagen-induced arthritis was induced in mice to determine if a choline-rich diet reduces arthritis progression. Results. The urinary metabolic fingerprint of patients with established RA differs from that of healthy controls and SLE patients. Markers of altered gut microbiota (trimethylamine-N-oxide, TMAO), and oxidative stress (dimethylamine) were upregulated in patients with RA. In contrast, markers of mitochondrial dysfunction (citrate and succinate) and metabolic waste products (p-cresol sulfate, p-CS) were downregulated in patients with RA. TMAO and dimethylamine were negatively associated with serum inflammatory markers in RA patients. In particular, patients with lower p-CS levels exhibited a more rapid radiographic progression over two years than did those with higher p-CS levels. The in vivo functional study demonstrated that mice fed with 1% choline, a source of TMAO experienced a less severe form of collagen-induced arthritis than did those fed a control diet. Conclusion. Patients with RA showed a distinct urinary metabolomics pattern. Urinary metabolites can reflect a pattern indicative of inflammation and accelerated radiographic progression of RA. A choline-rich diet reduces experimentally-induced arthritis. This finding suggests that the interaction between diet and the intestinal microbiota contributes to the RA phenotype.

Smoking, body mass index, disease activity, and the risk of rapid radiographic progression in patients with early rheumatoid arthritis

BackgroundIdentification of risk factors for rapid joint destruction in early rheumatoid arthritis (RA) can be helpful for optimizing treatment, and improving our understanding of destructive arthritis and its mechanisms. The objective of this study was to investigate the relationship between early RA patient characteristics and subsequent rapid radiographic progression (RRP).MethodsAn inception cohort of patients with early RA (symptom duration < 12 months), recruited during 1995–2005 from a defined area (Malmö, Sweden), was investigated. Radiographs of the hands and feet were scored in chronological order according to the modified Sharp–van der Heijde score (SHS), by a trained reader. RRP was defined as an increase of ≥ 5 points in SHS per year.ResultsTwo hundred and thirty-three patients were included. Radiographs were available from 216 patients at baseline, 206 patients at 1 year, and 171 patients at 5 years. Thirty-six patients (22%) had RRP up to 5 years. In logistic regression models, rheumatoid factor (RF) and anti-cyclic citrullinated peptides (anti-CCP), and increased erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) at baseline, predicted RRP over 5 years. Patients identified as overweight or obese had a significantly reduced risk of RRP up to 5 years (odds ratio (OR) 0.26; 95% confidence interval (CI) 0.11–0.63; adjusted for RF, baseline erosions, and ESR). Similar point estimates were obtained when stratifying for antibody status, and in models adjusted for smoking. A history of ever smoking was associated with a significantly increased risk of RRP up to 5 years, independent of body mass index (BMI) (OR 3.17; 95% CI 1.22–8.28; adjusted for BMI). At the 1-year follow-up, erosive changes, Disease Activity Score of 28 joints, Health Assessment Questionnaire, swollen joint count, and patient’s global assessment of disease activity and pain were also significantly associated with RRP up to 5 years.ConclusionsA history of smoking, presence of RF and/or anti-CCP and early erosions, high initial disease activity and active disease at 1 year, all increase the risk of RRP. Patients with a high BMI may have a reduced risk of severe joint damage. This pattern was not explained by differences in disease activity or antibody status. The results of this study suggest independent effects of smoking and BMI on the risk of RRP.

Contribution of bacterial pathogens to evoking serological disease markers and aggravating disease activity in rheumatoid arthritis.

Commensal bacteria and their pathogenic components in the gastrointestinal tract and oral cavity may play pathological roles in autoimmune diseases. To study the possible involvement of bacterial pathogens in autoimmune diseases, IgG and IgA antibodies against pathogenic components produced by three strains of commensal bacteria, Escherichia coli-lipopolysaccharide (E. coli-LPS), Porphyromonas gingivalis-LPS (Pg-LPS) and peptidoglycan polysaccharide (PG-PS) from Streptococcus pyogenes, were determined by an improved ELISA system for sera from two groups of patients with rheumatoid arthritis (RA), who met rapid radiographic progression (RRP) criteria and non-RRP, and compared to normal (NL) controls. Antibody responses to these bacterial pathogens are unique and consistent in individuals, and no fundamental difference was observed between RA and NL controls. Despite the similar antibody responses to pathogens, lower IgG or higher IgA and consequent higher IgA/IgG antibody ratio among the patients with RA related to disease marker levels and disease activity. Peculiarly, the IgA/IgG anti-Pg-LPS antibody ratio resulted from lower IgG and higher IgA antibody responses to Pg-LPS strongly correlated not only with rheumatoid factor (RF), but also correlated with erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and disease activity score of 28 joints with ESR (DAS28-ESR) in the RRP group. In contrast, the IgA/IgG anti-E. coli-LPS and anti-PG-PS antibody ratio correlated or tended to correlate with RF, ESR, CRP, and DAS28-ESR in the non-RRP group, whereas either the IgG or IgA anti-Pg-LPS antibody levels and consequent IgA/IgG anti-Pg-LPS antibody ratio did not correlate with any clinical marker levels in this group. Notably, anti-circular-citrullinated peptide (CCP) antibody levels, which did not correlate with either IgG or IgA antibody levels to any pathogens, did not correlate with severity of arthritis in both RRP and non-RRP. Taken together, we propose that multiple environmental pathogens, which overwhelm the host antibody defense function, contribute independently or concomitantly to evoking disease makers and aggravating disease activity, and affect disease outcomes.Trial registration: UMIN CTR UMIN000012200

Characteristics associated with joint replacement in early symptomatic knee or hip osteoarthritis: 6-year results from a nationwide prospective cohort study (CHECK).

Many patients with osteoarthritis (OA) of the knee and/or hip undergo total joint replacement (TJR) because of severely progressed symptoms. To determine patient and disease characteristics associated with undergoing TJR in participants with recent-onset knee and/or hip OA. Participants with hip or knee pain from the nationwide prospective Cohort Hip and Cohort Knee (CHECK) study were included. The outcome measure was total hip arthroplasty (THA) or total knee arthroplasty (TKA) during 6 years of follow-up. Joint-dependent characteristics were compared using generalised estimating equations (GEE). Multivariable models were built for both subgroups. Differences in symptomatic and radiographic progression were determined between baseline and 2-year follow-up (T2). The knee subgroup included 751 participants (1502 knees), and there were 538 participants in the hip subgroup (1076 hips). Nineteen participants (22 knees) underwent TKA and 53 participants (62 hips) THA. Participants who underwent TKA had higher baseline body mass index, painful knee flexion, and higher Kellgren and Lawrence scores. Participants who underwent THA had painful internal hip rotation and showed more severe radiographic OA features. Participants who underwent TKA or THA showed more rapid symptomatic and radiographic OA progression at T2. In patients with recent-onset knee or hip pain, radiographic OA features already exist and a substantial number of patients fulfil existing criteria for knee and hip OA. A trend was observed in rapid progression of radiographic and symptomatic OA severity among patients with TKA and THA. Early detection of OA by the GP is important in managing knee and hip OA.

Association of tumor necrosis factor-α (G-308A) genetic variant with matrix metalloproteinase-9 activity and joint destruction in early rheumatoid arthritis.

Matrix metalloproteinases (MMPs) are the key enzymes responsible for the joint destruction. Their activity is regulated by the level of proinflammatory cytokines. The aim of this study was to examine the impact of TNF-α G-308A polymorphism on MMP-9 levels in blood plasma (BP) and synovial fluid (SF) of patients with rheumatoid arthritis (RA) and their role in progression of joint destruction. One hundred thirty-four subjects were enrolled in this study. TNF-α G-308A polymorphism was determined using PCR-RFLP method. ELISA assay was used for the detection of MMP-9 activity in BP and SF. Joint damage was estimated by hands and feet radiography. Larsen score and annual changes in LS were used for quantitative evaluation of joint destruction and radiographic progression of disease. MMP-9 activity in BP and SF was significantly higher in RA compared to controls, as well as in SF of patients with erosive compared to nonerosive RA. Faster radiographic progression and increased MMP-9 activity in BP and SF were detected in the group A (GA or AA genotype carriers) compared to the group G (GG genotype carriers). However, statistical significance was revealed only for MMP-9 activity in SF (p<0.05). MMP-9 activity in BP and SF is significantly higher in RA patients compared to patients with osteoarthritis. The presence of TNF-α-308A allele is associated with increased MMP-9 activity in SF of patients with early RA and may be a predictor of rapid radiographic progression of disease.

Efficacy of golimumab for preventing large joint destruction in patients with rheumatoid arthritis as determined by the ARASHI score

Objectives: The objective of this study is to investigate the inhibitory effect of golimumab on large joint destruction in patients with rheumatoid arthritis.Methods: We recruited 45 patients with rheumatoid arthritis and evaluated the radiographic severity of large joint destruction using the assessment of rheumatoid arthritis by scoring of large joint destruction and healing in radiographic imaging (ARASHI) score. We evaluated 450 large joints including the elbow, shoulder, hip, knee, and ankle at baseline and 52 weeks after treatment with golimumab. Rapid radiographic progression (RRP) and rapid radiographic improvement (RRI) were calculated and the correlation between large joint destruction and clinical factors was analyzed.Results: The mean age of the study population was 61.29 ± 14.71 years old, and most patients (91.1%) were female. The mean disease duration was 12.6 ± 12.48 years. The cohort included patients in all clinical stages of disease as defined by the Steinbroker criteria (I:7, II:10, III:9, IV:19) as well as clinical classes 2 (n = 18), 3 (n = 26), and 4 (n = 1) and the mean disease activity score-CRP (DAS28-CRP) was 4.431 ± 1.044. Patients were treated with methotrexate (mean dose 6.44 ± 1.78 mg/week), prednisolone (PSL) (mean dose 1.078 ± 1.871 mg/d), and golimumab (44.4% of 100 mg). RRP was evident in 20% of the large joints treated with golimumab, and, therefore, golimumab was effective at inhibiting large joint destruction in 80% of joints. RRI was evident in 33.3% of large joints following golimumab treatment. We also observed that EULAR response criteria significantly correlated with the ARASHI change score at 52 weeks after treatment. The total ARASHI status score significantly correlated with the Sharp–van der Heijde score, but not with the delta total sharp score. Multiple regression analyses revealed that the total ARASHI change score was only correlated with EULAR response criteria significantly.Conclusions: Golimumab therapy was effective at inhibiting large joint destruction of RA patients who have good clinical response, including higher improvement of the shoulder and ankle joints than other large joints.

Impact of Dose Tapering of Tumor Necrosis Factor Inhibitor on Radiographic Progression in Ankylosing Spondylitis.

ObjectiveTo investigate the impact of dose reduction of tumor necrosis factor inhibitor (TNFi) on radiographic progression in ankylosing spondylitis (AS).MethodsOne hundred and sixty-five patients treated with etanercept or adalimumab were selected from a consecutive single-center observational cohort based on the availability of radiographs at baseline and after two- and/or four-years of follow up. Radiographs were assessed by two blinded readers using the modified Stokes AS Spinal Score (mSASSS). Radiographic progression in patients treated with standard-dose TNFi (standard-dose group, n = 49) was compared with patients whose dosage was tapered during the treatment (tapering group, n = 116) using linear mixed models.ResultsBaseline characteristics between two groups were comparable except for higher BASDAI (7.1 vs. 6.3, p = 0.003) in the standard-dose group. At two years after the treatment, mean dose quotient (S.D.) of the tapering group was 0.59 (0.17). During follow up, rate of radiographic progression in overall patients was 0.90 mSASSS units/year. Radiographic progression over time between the two groups was similar at the entire group level. However, in the subgroup of patients with baseline syndesmophytes, progression occurred significantly faster in the tapering group after the adjustment for baseline status (1.23 vs. 1.72 mSASSS units/year, p = 0.023). Results were consistent when radiographic progression was assessed by the number of newly developed syndesmophytes (0.52 vs. 0.73/year, p = 0.047). Sensitivity analysis after multiple imputation of missing radiographs also showed similar results.ConclusionA dose tapering strategy of TNFi is associated with more rapid radiographic progression in AS patients who have syndesmophytes at baseline.

The Scottish Early Rheumatoid Arthritis (SERA) Study: an inception cohort and biobank.

BackgroundThe Scottish Early Rheumatoid Arthritis (SERA) study is an inception cohort of rheumatoid (RA) and undifferentiated arthritis (UA) patients that aims to provide a contemporary description of phenotype and outcome and facilitate discovery of phenotypic and prognostic biomarkersMethodsDemographic and clinical outcome data are collected from newly diagnosed RA/UA patients every 6 months from around Scotland. Health service utilization data is acquired from Information Services Division, NHS National Services Scotland. Plain radiographs of hands and feet are collected at baseline and 12 months. Additional samples of whole blood, plasma, serum and filtered urine are collected at baseline, 6 and 12 monthsResultsResults are available for 1073 patients; at baseline, 76 % were classified as RA and 24 % as UA. Median time from onset to first review was 163 days (IQR97-323). Methotrexate was first-line DMARD for 75 % patients. Disease activity, functional ability and health-related quality of life improved significantly between baseline and 24 months, however the proportion in any employment fell (51 to 38 %, p = 0.0005). 24 % patients reported symptoms of anxiety and/or depression at baseline. 35/391 (9 %) patients exhibited rapid radiographic progression after 12 months. The SERA Biobank has accrued 60,612 samplesConclusionsIn routine care, newly diagnosed RA/UA patients experience significant improvements in disease activity, functional ability and health-related quality of life but have high rates of psychiatric symptoms and declining employment rates. The co-existence of a multi-domain description of phenotype and a comprehensive biobank will facilitate multi-platform translational research to identify predictive markers of phenotype and prognosisElectronic supplementary materialThe online version of this article (doi:10.1186/s12891-016-1318-y) contains supplementary material, which is available to authorized users.

Magnetic Resonance Imaging Bone Edema at Enrollment Predicts Rapid Radiographic Progression in Patients with Early RA: Results from the Nagasaki University Early Arthritis Cohort.

To clarify whether magnetic resonance imaging (MRI) bone edema predicts the development of rapid radiographic progression (RRP) in the Nagasaki University Early Arthritis Cohort of patients with early-stage rheumatoid arthritis (RA). Patients with early-stage RA (n = 76) were enrolled and underwent 1.5-T MRI of both wrists and finger joints. Synovitis, bone edema, and bone erosion were evaluated using the Rheumatoid Arthritis Magnetic Resonance Imaging Scoring (RAMRIS). RRP was defined as an annual increment > 3 at 1 year by the Genant-modified Sharp score of plain radiographs. A multivariate logistic regression analysis was performed to establish the risk factors for RRP. Median disease duration at enrollment was 3 months. RRP was found in 12 of the 76 patients at 1 year. A univariate analysis revealed that matrix metalloprotease-3, RAMRIS bone edema score, and RAMRIS bone erosion score were associated with RRP. Multivariate logistic regression analyses demonstrated that the RAMRIS bone edema score at enrollment (5-point increase, OR 2.18, 95% CI 1.32-3.59, p = 0.002) was the only independent predictor of the development of RRP at 1 year. A receiver-operating characteristic analysis identified the best cutoff value for RAMRIS bone edema score as 5. RRP was significantly rare among the patients with a RAMRIS bone edema score < 5 at enrollment (2 from 50 patients). Our findings suggest that MRI bone edema is closely associated with the development of RRP in patients with early-stage RA. Physicians should carefully control the disease activity when MRI bone edema is observed in patients with early RA.

Performance of matrices developed to identify patients with early rheumatoid arthritis with rapid radiographic progression despite methotrexate therapy: an external validation study based on the ESPOIR cohort data

IntroductionUse of prediction matrices of risk or rapid radiographic progression (RRP) for early rheumatoid arthritis (RA) in clinical practice could help to better rationalise the first line of treatment. Before...

MMP-3 as a predictor for structural remission in RA patients treated with MTX monotherapy.

BackgroundThe study was undertaken to assess the efficacy of methotrexate (MTX) monotherapy on the radiographic progression of individual rheumatoid arthritis (RA) patients, each of whom had received MTX monotherapy for 3 years with an option to change to biological disease-modifying anti-rheumatic drugs (bDMARDs). We also looked for predictors of radiographic non-progression in these patients.MethodsRheumatoid patients (n = 161) were prospectively followed for 3 years while receiving low-dose MTX monotherapy unless disease was otherwise active and/or adverse events appeared. Their disease activity and radiographic progression were evaluated with reference to disease activity score 28 (DAS28), modified health assessment of questionnaire (mHAQ) and other indices. The change in van der Heijde-modified total Sharp score per year (∆TSS) was assessed using probability plots, in which the patients were classified into the subgroups showing structural remission (REM; ∆TSS ≤0.5), radiographic progression (∆TSS >3) or rapid radiographic progression (RRP; ∆TSS >5).ResultsMTX monotherapy, continued until disease became active and/or adverse event appeared, was associated with a significant improvement (p <0.0001) in the DAS28-ESR (3) scores, % DAS28 remission, and mHAQ scores each year, from baseline to 3 years. The mHAQ remission rate (∆mHAQ <0.5) and Boolean remission were also improved from 16 to 60 % and 0.8 to 24.0 %, respectively. We found that the ratio of patients classified as REM increased yearly from 62/161 (38.5 %) to 69/137 (50.4 %), while those classified as ∆TSS >3 decreased from 55/161 (34.2 %) to 28/137 (20.4 %) and those in RRP decreased from 35/161 (21.7 %) to 15/137 (10.9 %). Receiver operating characteristic (ROC) curve analyses showed that serum matrix metalloproteinase-3 (MMP-3) <103.7 ng/ml at outset predicts a patient subgroup that exhibits no radiographic progression.ConclusionsHalf of rheumatoid patients treated with MTX monotherapy for 3 years exhibited structural remission, and this outcome can be predicted at the outset by lower serum MMP-3.Electronic supplementary materialThe online version of this article (doi:10.1186/s13075-016-0948-7) contains supplementary material, which is available to authorized users.

Identification of novel urinary biomarkers for assessing disease activity and prognosis of rheumatoid arthritis.

To optimize treatment for rheumatoid arthritis (RA), it is ideal to monitor the disease activity on a daily basis because RA activity fluctuates over time. Urine can be collected routinely at home by patients. Recently, we identified four urinary biomarker candidates—gelsolin (GSN), orosomucoid (ORM)1, ORM2 and soluble CD14 (sCD14)—in RA patients through transcriptomic and proteomic studies. Here, we investigated the clinical significance of the aforementioned urinary biomarker candidates in a prospective manner. For the first time, we found that urinary ORM1, ORM2 and sCD14 levels, but not GSN, were elevated in RA patients and had a positive correlation with the status of the disease activity. In particular, urine tests for ORM 1, ORM 2 and sCD14 efficiently represented the presence of high RA activity without the need for measuring blood markers. In a parallel study, a more rapid radiographic progression over 3 years was observed in patients with higher ORM2 levels. Combined measurements of urinary ORM2 and serum C-reactive protein synergistically increased the predictability of the radiographic progression of RA (odds ratio: 46.5). Collectively, our data provide evidence that blood-free, urinary biomarkers are promising surrogates for assessing disease activity and prognosis of RA. We anticipate that our urinary biomarkers will provide novel candidates for patient-driven measurements of RA activity at home and can shift the paradigm from blood to urine testing in the assessment of RA activity and prognosis in hospitals.
