ABSTRACT
Purpose: To investigate the disease activity in real-world patients with rheumatoid arthritis (RA) who switched from originator etanercept (ETN) to biosimilar YLB113. Methods: Forty one RA patients who switched from ETN to YLB113 were divided into 2 groups based on the Disease Activity Score based on the 28-joint count (DAS28) 12 months after switching (R group: DAS28 < 2.6, N group: DAS28 ≥ 2.6), and the baseline characteristics were statistically examined. A receiver operating characteristics (ROC) analysis was performed to estimate the cut-off value of DAS28 at baseline to achieve remission 12 months after switching. Results: There was no significant difference in the DAS28 at baseline and 12 months after switching (p = .83). Sixteen out of the 20 patients in remission at baseline achieved remission after switching. A univariate analysis revealed the rheumatoid factor (p = .04) and DAS28 (p < .001) at baseline were significantly lower in the R group than in the N group. Furthermore, logistic regression analysis revealed DAS28 was an independent factor (p = .004) for achieving remission 12 months after switching. An ROC curve analysis showed the optimal cut-off value for DAS28 at baseline to achieve remission at 12 months after switching was 2.5. Conclusions: RA patients who achieved remission using originator ETN, were able to maintain remission even if they switched to YLB113.

BACKGROUND: The influence of biological disease-modifying antirheumatic drugs (bDMARDs) on postoperative surgical site infection (SSI) and venous thromboembolism (VTE) in patients with rheumatoid arthritis (RA) has not yet been clarified. METHODS: A systematic literature search was performed using PubMed, Web of ScienceTM, Scopus, and The Cochrane Library databases to identify eligible studies published up to August 2023. All studies comparing postoperative SSI or VTE rates in RA patients with or without bDMARD treatment were included. The protocol for this study was registered in PROSPERO (CRD42021246264) and is available on the University of York website. RESULTS: Overall, 20 studies with 71,885 RA patients and 6 studies with 7918 RA patients were included for postoperative SSI and VTE comparisons, respectively. Patients treated with bDMARDs had significantly higher rates of postoperative SSI than those without treatment (odds ratio 1.50, 95% confidence interval 1.23-1.83, Pâ <â .0001). However, these significant differences disappeared in the analysis restricted to 9 studies involving non-tumor necrosis factor α inhibitors. The use of bDMARDs seemed to increase the rate of postoperative VTE (odds ratio 2.20, 95% confidence interval 1.30-3.72, Pâ =â .003). A subgroup analysis showed that postoperative osseous complications were significantly less frequent in RA patients with bDMARD treatment than in those without treatment. CONCLUSION: RA patients treated with bDMARDs had an increased risk of not only postoperative SSI but also VTE. While bDMARD usage merits appropriate attention, there might be positive aspects as well. Further data will be needed to confirm the postoperative risks of bDMARD usage in RA patients.

BACKGROUND: This study evaluated the existence of anti-drug antibodies (ADAs) before and 52 weeks after switching from intravenous infliximab (IFX) to intravenous CT-P13 in patients with rheumatoid arthritis (RA). METHODS: We performed a prospective observational study. Twenty-eight patients (7 males and 21 females) received intravenous CT-P13 after intravenous IFX, and the clinical data were collected from medical records. Rheumatoid factor (RF) and anti-CCP antibody were examined at baseline. At baseline and 52 weeks after the start of CT-P13 treatment, the Disease Activity Score based on the 28-joint count and the levels of C-reactive protein, matrix metalloproteinase-3, and ADA, as well as the erythrocyte sedimentation rate were evaluated. ADAs were measured using an enzyme-linked immunosorbent assay kit. RESULTS: Seven (25%) and 6 (21.4%) cases were positive for ADAs at baseline and 52 weeks after, respectively. One case became newly positive for ADAs at week 52. Two of the ADA-positive cases became ADA-negative 52 weeks after. The ADA-positive group showed significantly higher RF values at baseline than the ADA-negative group (p = 0.03). No difference was observed between the ADA-positive group and the ADA-negative group regarding other clinical parameters. CONCLUSIONS: The positive rate of ADAs did not increase after switching from intravenous IFX to intravenous CT-P13. Among the patients with ADAs, a high level of RF was observed at baseline.
ABSTRACT
OBJECTIVES: TNF-induced activation of fibroblast-like synoviocytes (FLS) is a critical determinant for synovial inflammation and joint destruction in RA. The detrimental role of TNF-receptor 1 (TNFR1) has thoroughly been characterized. The contributions of TNFR2, however, are largely unknown. This study was performed to delineate the role of TNFR2 in human FLS activation. METHODS: TNFR2 expression in synovial tissue samples was determined by immunohistochemistry. Expression of TNFR2 was silenced using RNAi or CRISPR/Cas9 technologies. Global transcriptional changes were determined by RNA-seq. QPCR, ELISA and immunoblotting were used to validate RNA-seq results and to uncover pathways operating downstream of TNFR2 in FLS. RESULTS: TNFR2 expression was increased in RA when compared with OA synovial tissues. In particular, RA-FLS demonstrated higher levels of TNFR2 when compared with OA-FLS. TNFR2 expression in RA-FLS correlated with RA disease activity, synovial T- and B-cell infiltration. TNF and IL1ß were identified as inflammatory mediators that upregulate TNFR2 in RA-FLS. Silencing of TNFR2 in RA-FLS markedly diminished the TNF-induced expression of inflammatory cytokines and chemokines, including CXCR3-binding chemokines and the B-cell activating factor TNFSF13B. Immunobiochemical analyses revealed that TNFR2-mediated expression of inflammatory mediators critically depends on STAT1. CONCLUSION: Our results define a critical role for TNFR2 in FLS-driven inflammation and unfold its participation in the unresolved course of synovial inflammation in RA.

BACKGROUND: Throwing-related shoulder and elbow pain continues to be reported among adolescent baseball players. Few prospective studies have specifically examined the association between throwing-related shoulder and elbow pain and physical and developmental changes. PURPOSE: To evaluate the changes in physical and developmental characteristics during 1 year with respect to throwing-related shoulder and elbow pain in adolescent baseball players. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: This 1-year prospective follow-up study investigated 164 baseball players aged 7 to 13 years. Player data (age, height, weight, field position, and pitch count), lower extremity muscle tightness, and range of motion (ROM) of the shoulder, elbow, and hip joints were assessed during the 2016 and 2017 preseason medical examinations. After the 2016 season, the participants completed questionnaires related to throwing-related shoulder and elbow pain, defined as an inability to play for ≥1 week because of elbow or shoulder difficulties. For study participants with and without throwing-related shoulder or elbow pain during the 2016 season, we conducted univariate and multivariate logistic regression analysis to identify risk factors for throwing-related shoulder or elbow pain. RESULTS: Overall, 21 players (12.8%) reported a shoulder pain episode, 56 players (34.1%) had an elbow pain episode, and 70 players (42.7%) reported having experienced shoulder and/or elbow pain during the 2016 season. In multivariate logistic regression analysis, (1) shoulder pain was associated with 2016 preseason height (odds ratio [OR], 1.06; 95% CI, 1.01-1.11; P = .01) and change in dominant-side elbow extension ROM from 2016 to 2017 (OR, 1.12; 95% CI, 1.02-1.24; P = .02); (2) elbow pain was associated with change in weight from 2016 to 2017 (OR, 1.21; 95% CI, 1.04-1.41; P = .014); and (3) throwing-related shoulder and/or elbow pain was associated with greater 2016 preseason height (OR, 1.04; 95% CI, 1.003-1.68; P = .03) and an increase in height from 2016 to 2017 (OR, 1.17; 95% CI, 1.01-1.35; P = .03). CONCLUSION: Our results indicated that adolescent baseball players who were taller in the preseason and those with an increase in height over the 1-year study period faced significant risks for developing throwing-related shoulder and/or elbow pain.
ABSTRACT
OBJECTIVES: Rheumatoid arthritis (RA) patients have an increased risk of cardiovascular disease (CVD). In the present study, we evaluated the inflammatory activity of the ascending aorta in RA patients who received biological treatment. METHODS: We assessed the aortic wall inflammation of RA patients using 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography before and after 6 months of biologic therapies. We also compared the inflammatory activity at the aortic wall in RA patients with remission or low disease activity (RLDA) and those with moderate or high disease activity (MHDA). The aortic uptake was measured by the standardized uptake value (SUV) and the target-to-background ratio (TBR). RESULTS: A total of 64 patients were included in the analysis (mean age, 58.4 ± 13.8 years old; female, 77%). The Disease Activity Score for 28 joints (DAS28) erythrocyte sedimentation rate (ESR) had significantly decreased after 6 months: from 5.0 ± 1.2 to 3.3 ± 1.2 (p < 0.001). The FDG uptake in the ascending aorta changed from baseline to 6 months, showing a maximum SUV (SUVmax) of 1.83 ± 0.34 to 1.90 ± 0.34 (p = 0.059) and TBR of 1.71 ± 0.23 to 1.75 ± 0.24 (p = 0.222). The SUVmax and TBR after 6 months were significantly higher in the RLDA group than in the MHDA group (2.05 ± 0.32 vs. 1.79 ± 0.33 (p = 0.002) and 1.89 ± 0.33 vs. 1.65 ± 0.20 (p = 0.001), respectively). The percentage of monocytes also significantly increased from baseline to 6 months: from 5.9 ± 1.6 to 6.9 ± 2.6 (p = 0.032). CONCLUSION: The inflammation activity at the ascending aorta in RA patients did not change significantly after 6 months of biological treatment. RA patients with a low disease activity or in clinical remission after 6 months of biological treatment still had an increased inflammatory activity at the aortic wall.

OBJECTIVE: The hip joint is a crucial part of the kinetic chain for throwing baseball pitches. Nevertheless, few reports have described assessments of the functional development of the hip joint in young baseball players. METHODS: We examined 315 young baseball players, 7-14 years old, all of whom had completed a self-administered questionnaire including items related to the dominant side and throwing-related hip joint pain sustained during the previous year. We measured the hip ranges of motion (ROMs: external and internal rotation and flexion) and hip muscle strengths (external and internal rotation) on the dominant and non-dominant sides. The differences of hip ROMs and muscle strengths between the dominant and non-dominant sides and between age groups were investigated. Correlations were calculated between the players ages and hip ROMs and muscle strengths. RESULTS: No baseball player reported hip pain. The hip external rotation on the dominant side was smaller than that on the non-dominant side, whereas the hip internal rotation on the dominant side was greater than that on the non-dominant side. However, no significant difference was found between the dominant and non-dominant sides in terms of the hip muscle strength. Significant positive associations were found between the player's age and hip muscle strengths, whereas significant negative associations were found between the age and hip ROMs. CONCLUSIONS: Our data concerning the relationship between age and hip joint development could be useful for supporting strategies for the prevention and rehabilitation of throwing injuries; however, hip injuries might be rare among young baseball players.
ABSTRACT
OBJECTIVES: Molecular imaging constitutes a promising technique for the early detection of rheumatoid arthritis (RA). Macrophages and hypoxia play significant roles in inflamed synovium. In the present study, we evaluated the efficacy of radiopharmaceuticals that target macrophage mannose receptors (99mTc-labeled mannosylated dextran or 99mTc(CO)3-DCM20) and hypoxia (copper(II) diacetyl-di(N4-methylthiosemicarbazone) or Cu-ATSM) for the early detection of RA in collagen-induced arthritis (CIA) mice models. METHODS: CIA model was developed in DBA/1 mice, and the clinical score for arthritis was visually assessed on a regular basis. Two biodistribution studies were performed in a paired-labeled format using 2-deoxy-2-18F-fluoro-D-glucose (18F-FDG) as a reference: (1) 99mTc(CO)3-DCM20 with 18F-FDG and (2) 67Cu-ATSM with 18F-FDG. RESULTS: The accumulation levels of 99mTc(CO)3-DCM20 and 67Cu-ATSM in forepaws, hindpaws, and knee joints of CIA mice were significantly higher than that of control mice. In contrast, 18F-FDG uptake in hindpaws and knee joints showed no significant difference between CIA and control mice. The radioactivity levels of 99mTc(CO)3-DCM20 and 67Cu-ATSM were significantly correlated with the clinical scores for the paws. CONCLUSION: These results suggest the potential usefulness of 99mTc(CO)3-DCM20 and radiolabeled Cu-ATSM for the imaging and early detection of RA.

BACKGROUND: Rheumatoid arthritis (RA) and periodontitis (PD) have been suggested to share many clinical and pathological features. However, few reports have investigated the relationship between the degree of PD and the treatment response to RA. This study aimed to examine the relationship between the extent of PD and the treatment response to biologics in RA patients using FDG-PET/CT. METHODS: Sixty RA patients (male, n = 14; female, n = 46; average age, 58.3 years) treated with biologic agents were included in this study. FDG-PET/CT was performed at baseline and 6 months after the initiation of biological therapy. The maximum standardized uptake value (SUVmax) was used as a representative value for the assessment of the FDG uptake in periodontal tissue and joints including the bilateral shoulders, elbows, wrists, hip, knees, and ankle joints. The Disease Activity Score (DAS) 28-CRP and the following clinical parameters were assessed: C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), anti-cyclic citrullinated peptide antibody (ACPA), rheumatoid factor (RF), and matrix metalloproteinase 3 (MMP-3). The relationship between the treatment response of RA and the baseline SUVmax of the periodontal tissue was evaluated. RESULTS: The baseline periodontal SUVmax was related to patient age (r = 0.302, p = 0.009) and the ACPA level (r = 0.265, p = 0.025). The DAS28-CRP, CRP, ESR, MMP-3, and joint SUVmax values were significantly decreased after 6 months of biological therapy. However, the mean periodontal SUVmax, ACPA, and RF showed no significant changes after treatment. There was a significantly negative correlation between the baseline periodontal SUVmax and the treatment response of DAS28-CRP (r = - 0.369, p = 0.004). CONCLUSION: There was a negative correlation between the extent of PD at baseline and the treatment response of RA patients who received biological therapy. The evaluation of the periodontal condition is considered to be an essential part for the management of RA.

The aim of this study was to assess the association between the shoulder tenderness and the inflammatory changes on magnetic resonance imaging (MRI) in the rheumatoid shoulder. Forty-one shoulders of 41 patients with rheumatoid arthritis (RA) were examined. We evaluated synovitis, erosion and bone marrow edema, by counting the numbers of each positive site, and rotator cuff tears on shoulder MRI. The association between the shoulder tenderness and the MRI findings were statistically analyzed. Twenty-three of 41 patients had tenderness in the shoulder joints. There were 20 shoulders (48.8%) with rotator cuff tear, and no significant difference was observed in the prevalence of rotator cuff tear between the tenderness group and non-tenderness group (p = 0.080). There were no significant differences in the demographic data between these two groups. In MRI findings, we found significant difference for the synovitis (p = 0.001) and bone marrow edema (p = 0.021). Synovitis was strongly associated with the shoulder tenderness (OR: 3.996, 95% CI: 1.651-9.671). Synovitis was the factor most associated with shoulder tenderness.

BACKGROUND: To compare the efficacy of 12-month denosumab treatment on bone mineral density (BMD) and bone turnover markers (BTMs) between treatment-naïve osteoporosis patients with rheumatoid arthritis (RA) and those with previous bisphosphonate (BP) therapy. METHODS: A total of 36 RA patients with osteoporosis completed 12-month follow-up. Twenty-five patients were osteoporotic treatment-naïve (naïve group), and 11 patients were previously treated with BPs (switch group) (average 7.9 years). BMD and BTMs were measured before and 6 and 12 months after treatment. RESULTS: BTM levels were higher in the naïve group at baseline. However, the same level of suppression was achieved at 6 months in both groups. Spine BMD increased significantly in both groups. There was no significant difference in the mean percent changes of BMD of the spine (naïve group: 6.8 ± 0.8, switch group: 5.1 ± 1.5), femoral neck (2.9 ± 1.4, 2.9 ± 1.3), and total hip (1.7 ± 0.9, 1.4 ± 1.1) between these two groups at 12 months. CONCLUSIONS: The effects of denosumab on BMD and BTMs of the switch group after long-term BP treatment are comparable to those of the naïve group in RA patients. Thus, switching BPs to denosumab is one of the useful options to treat osteoporosis with RA.
ABSTRACT
Objectives: To assess the middle-term outcome of iguratimod (IGU) in rheumatoid arthritis (RA) patients. Methods: Sixty-nine RA patients (14 males and 55 females, mean age of 64.0 years) receiving IGU-containing therapies were enrolled. We divided these patients into three groups based on the treatment at the baseline: an IGU group, a methotrexate (MTX) plus IGU group, and a biologics plus IGU group. The baseline characteristics and clinical course were evaluated over three years. Predictive factors associated with the achievement of low disease activity (LDA) were statistically analyzed. Results: The survival rate of IGU therapy at 3 years was 40.6%. The disease activity was significantly decreased in the IGU group and MTX plus IGU group compared with the baseline. Furthermore, 38 patients (55.1%) were in remission or had LDA at 3 years. The patient gender, use of prednisolone (PSL) and DAS28-CRP at baseline were the factors associated with the achievement of remission or LDA at three years. Conclusion: IGU was effective without MTX or bDMARDs as well as in combination with MTX. A female gender, no use of PSL and a low DAS28-CRP at the initiation of IGU were associated with clinical remission or LDA achievement at three years.

AIM: A retrospective questionnaire survey was conducted to investigate the long-term outcomes of elbow, wrist and hand surgery for rheumatoid arthritis (RA). METHODS: One hundred and thirteen RA patients underwent primary elective elbow, wrist or hand surgery at our hospital between January 2002 and December 2003. To evaluate the outcomes at 10 years after surgery, the patient-reported outcomes were assessed using an original questionnaire that inquired about the site of treatment; the modified Stanford Health Assessment Questionnaire (mHAQ) was also used. RESULTS: Responses were obtained from 67 patients (98 sites). In the 10 years after surgery, the Disease Activity Score of 28 joint - erythrocyte sedimentation rate (4) and the modified Health Assessment Questionnaire scores of the patients showed significant improvement. Nearly 85% of patients were satisfied with the outcome at the surgical site. The most frequent reason for perceived improvement was 'pain relief' (all surgical sites). An 'improved appearance' was frequently reported after finger surgery and 'increased power' was frequently reported after wrist and thumb surgeries. With regard to elbow surgery, 30% of the patients were satisfied with the increase in motion and power. In contrast, approximately 20% of patients complained of decreased power around the surgical site after elbow and thumb surgeries. CONCLUSIONS: Our original patient-reported outcome assessment tool revealed that elbow, wrist and hand surgery provided long-lasting benefits in RA patients. While the efficacy differed in some of the surgical sites, pain relief was the most favorable effect. Altered medical therapy may also have impacted the patient-perceived outcomes of surgery at 10 years.

OBJECTIVE: The aim of this study was to compare the efficacy of six-month teriparatide treatment followed by six-month bisphosphonate therapy with 12-month bisphosphonate monotherapy in Japanese rheumatoid arthritis (RA) patients who had not been previously treated for osteoporosis. METHODS: A total of 34 RA patients with osteoporosis were enrolled. Thirteen patients received six-month teriparatide prior to six-month minodronate therapy (PTH group), and 21 patients received 12-month minodronate therapy (BP group). Bone mineral density (BMD), and bone turnover markers were measured prior to and 6 and 12 months after the initiation of treatment. RESULTS: Bone mineral density of the spine was significantly increased after 12 months of treatment in both groups. In the PTH group, the mean percent change of BMD of the spine was significantly higher at 12 months after the initiation of treatment, as compared to the BP group (PTH group: 9.9 ± 1.5%, BP group: 5.5 ± 0.7%). Femoral neck BMD was significantly increased only in the PTH group after 12 months. CONCLUSION: Therapy involving six-month teriparatide followed by six-month minodronate therapy increased spine BMD to a greater degree than 12-month minodronate monotherapy. The strategy of short-term administration of teriparatide for RA patients with osteoporosis might be useful when additional bisphosphonate therapy is considered.

We evaluated the state of osteopenia and the physical function in 121 schizophrenic patients. These factors were worse in the inpatient group than in the outpatient group. The age, sex, body mass index (BMI), and physical function were correlated to the state of osteopenia. Physicians should consider the risk of osteopenia in elderly female psychiatric patients with low BMI. PURPOSE: Information about the actual state of osteopenia in patients with schizophrenia is limited. In the present study, we evaluated the factors related to osteopenia and patient's physical function and compared these factors between inpatients and outpatients. METHODS: A total of 121 schizophrenic patients were included in the present study. We divided the patients into two groups according to the therapeutic form. We collected data on their age, sex, body mass index (BMI), bone mineral density (BMD) in the lumbar spine and proximal femur, serum bone metabolic markers, risk of fracture, and physical function. RESULTS: The number of fractured vertebrae, risk of fracture, serum concentration of tartrate-resistant acid phosphatase 5b (TRACP-5b), and score of locomo25 were significantly higher and the BMI and BMD in the lumbar spine and proximal femur significantly lower in the inpatient group than in the outpatient group. A multiple regression analysis showed that the age, sex, BMI, the number of fractured vertebrae, and score of locomo 25 were correlated with the BMD in the lumbar spine and proximal femur. Neither the therapeutic form nor any bone metabolic markers were correlated with the BMD. The inpatient group had a lower average BMI, BMD, and physical function than the outpatient group. However, a multiple regression analysis showed that the therapeutic form was not correlated with the BMD. CONCLUSION: These findings suggest that physicians should consider elderly female schizophrenic patients with a low BMI to be at risk of developing osteopenia.

AIM: Rotator cuff disease (RCD) is one of the most common disorders in the shoulder joint and causes joint pain and functional disability. In this study, we investigated the associations among cytokine levels and clinical symptoms in patients with RCD. METHOD: Joint fluid specimens of the shoulder joint were obtained from 38 patients with RCD before arthroscopic surgery. The levels of inflammatory cytokines, including interleukin (IL)-1ß, IL-6 and IL-8, were evaluated using enzyme-linked immunosorbent assay kits, and the associations between these cytokine levels and the clinical symptoms were determined. A multiple linear regression analysis was performed to identify the parameters accounting for the visual analogue scale (VAS) score at rest. RESULTS: IL-8 level was correlated with IL-6 (r = 0.434, P = 0.006) and IL-1ß (r = 0.575, P < 0.001) levels. The cuff tear size was inversely correlated with the VAS score at rest. A multiple stepwise linear regression analysis revealed that the VAS score at rest could be explained by the VAS score at night, the VAS score during movement and the intra-articular IL-8 level (adjusted R² = 0.544, P < 0.001). The intra-articular IL-8 level is associated with resting pain in rotator cuff tear patients. CONCLUSION: These results suggest that an increased concentration of IL-8 is associated with resting pain in rotator cuff tear patients.

AIM: The objective of this study was to assess arthritis of the whole body before and after total knee arthroplasty (TKA) in patients with rheumatoid arthritis (RA) using positron emission tomography (PET). METHOD: Seventeen knees of 17 RA patients (median age 68 years) who underwent TKA were included in this study. Clinical assessments of disease activity, knee function and activities of daily living (ADL) were performed before and after TKA. 18 Fluorodeoxyglucose (FDG)-PET was performed preoperatively and 12 weeks postoperatively when RA disease activity was assessed. The maximal standardized uptake value (SUV) in the region of interest was used to assess FDG uptake. RESULTS: Disease activity and knee function improved in all patients after TKA. There was a significant decrease in the number of patients with swollen or tender joints involving the right wrist, right knee and left knee. The SUV of bilateral wrist joints decreased significantly 12 weeks after TKA, whereas the SUVs of other large joints were unchanged. CONCLUSION: TKA can improve not only ADL and knee function, but also the disease activity index in RA patients. However, TKA has limited effectiveness against synovitis of the joints not undergoing surgery.

OBJECTIVES: The purpose of this study was to clarify the characteristics of bony ankylosis of the facet joint of the cervical spine in rheumatoid arthritis (RA) patients who required cervical spine surgery, and its relationship to the clinical findings. METHODS: Eighty consecutive RA patients with cervical spine disorder who received initial surgery were reviewed. The occurrence of bony ankylosis of the facet joint of the cervical spine was investigated using computed tomography (CT) before surgery. We also evaluated the severity of neurological symptoms and the plain wrist radiographs taken before surgery; furthermore, we evaluated each patient's medical history for total knee arthroplasty (TKA) or hip arthroplasty (THA). RESULTS: The preoperative CT imaging demonstrated bony ankylosis of the facet joint of the cervical spine in 45 facet levels of 19 cases (BA + group). In all patients, responsible instability or stenosis was demonstrated just caudal or on the cranial side of those bony ankylosis. Before surgery, the BA + group included significantly more patients showing severe cervical myelopathy (p < 0.05), and significantly more cases showing progressed ankylosis in the wrist joint bilaterally (p < 0.01). There were also significantly more patients who received two or more TKA or THA before the cervical spine surgery in the BA + group (p < 0.01). CONCLUSIONS: Bony ankylosis of the facet joint of the cervical spine may be a risk factor of instability or stenosis at the adjacent disc level and severe cervical myelopathy. Furthermore, its ankylosis was demonstrated in RA patients with severe destroyed joints.

OBJECTIVE: To investigate the associations between large-joint damage and findings on fluorodeoxyglucose positron emission tomography combined with computed tomography (FDG-PET/CT) using the "assessment of rheumatoid arthritis by scoring of large-joint destruction and healing in radiographic imaging (ARASHI)" scoring system. METHODS: A total of 270 large joints (shoulders, elbows, hips, knees, and ankles) in 27 rheumatoid arthritis patients were assessed. FDG-PET/CT was performed at the initiation of biologics. Radiographs at baseline and at 3 years were evaluated using the ARASHI score. RESULTS: Radiographic progression of damage was detected in 35 by Larsen grade vs. 87 by the ARASHI score. The maximum standardized uptake value (SUVmax) at baseline, Steinbrocker stage at baseline, concomitant prednisolone use, and disease activity score in 28 joints based on erythrocyte sedimentation rate (DAS28-ESR) at 6 months were significantly higher in the radiographic progression group. An SUVmax higher than 1.65 at baseline was a significant predictive factor for progressive damage at 3 years. CONCLUSIONS: The ARASHI score may allow more detailed evaluation of large joints than the Larsen method. Joint destruction is likely to have progressed at 3 years in large joints, which had a higher SUVmax at the initiation of biologics.

OBJECTIVE: The aim of this study was to assess the risk factors for shoulder joint destruction in rheumatoid arthritis (RA) patients treated with biologics. METHODS: Thirty shoulders of 29 patients with RA were assessed using 18F-fluorodeoxyglucose positron emission tomography (PET) and magnetic resonance imaging (MRI) before starting biologics and 6 months later. The mean age (range) was 54 (18-72) years, and the mean disease duration was 7 (0.8-30) years. The radiographic findings were assessed at baseline and 3 years later. The inflammation markers and RA disease activity were also assessed. These parameters were compared between the progression of joint destruction group and the no progression group. RESULTS: The SUVmax on PET, the rate of synovitis, and the rate of rotator cuff tear on MRI before biologic treatment were significantly higher in the progression of joint destruction group. SUVmax and synovitis on MRI after 6 months were also significantly higher in the progression of joint destruction group. On logistic regression analysis, the SUV at baseline of the shoulder joint was the main risk factor for joint destruction. CONCLUSION: The detection of synovitis by imaging was more important than disease activity and inflammation markers for assessing the progression of shoulder joint destruction.
