RESUMO
OBJECTIVES: Impact of osteoarthritis (OA) on the initial treatment response of rheumatoid arthritis (RA) by treat to target (T2T) practice was compared between the patients with an onset age ≥65 years old (late-onset RA [LORA]) and those with an onset age <65 years old (young-onset RA [YORA]). METHODS: A retrospective study was conducted on the patients with RA, who were referred to our clinic without treatment between January 2021 and July 2022. Patients with grade ≥3 OA according to the Kellgren-Lawrence (K-L) classification either in the knee or hand were classified in the OA(+) group and others were in the OA(-) group. The clinical data were compared at the diagnosis and one year after the initial treatment between the groups for 74 LORA and 59 YORA patients, respectively. RESULTS: One year after starting treatment in the LORA patients, the OA(+) group had poorer disease activity control and greater disability in the several activities of daily living (ADL) than the OA(-) group. In the YORA patients, there were no differences in ADL disability between the groups. CONCLUSIONS: In the initial treatment of the LORA patients, the prevalence of OA was high, and impact of OA on LORA was larger than on YORA.
RESUMO
BACKGROUND: In recent years, advances in pharmacotherapy for rheumatoid arthritis (RA) have dramatically improved the control of disease activity. However, a significant number of patients still develop forefoot deformity. The purpose of this study was to investigate the results of more than 20 years' follow-up of metatarsal neck shortening oblique osteotomy (SOO) for forefoot deformity in patients with RA. METHODS: The metatarsal neck SOO was performed on 163 feet in 108 patients between January 1985 and December 1996 in the authors' hospital. For the patients, who met the survey criteria, an observational study was performed clinically and radiologically at the baseline and at more than 20 years after surgery. RESULTS: A retrospective cohort study was conducted on 36 feet in 22 patients, all of whom were female, and the mean age at surgery was 45.6 (35.0-63.0) years old. The follow-up period was 25.1 (21.0-31.0) years. The presence of painful callosities in the surgically treated feet without revised surgeries decreased from 32 feet (100%) to 4 feet (12.5%) at the last follow-up with mild pain that did not cause any footwear problems. Re-osteotomy at the metatarsal of the lessor toe was performed on four feet in two patients. Radiologically, among 128 toes without revised surgeries, 85% were able to have the joint space preserved, and 89% maintained a pain-free condition without any recurrence of deformity. The mean total Japanese Society for Surgery for the Foot (JSSF) RA foot and ankle score was 64.0/100, and the visual analogue scale (VAS) of overall satisfaction was 62 (0: dissatisfied, 100: highly satisfied). The overall satisfaction had a positive correlation with calcaneal pitch and negative correlation with joint space narrowing at the talocrural joint. CONCLUSIONS: Metatarsal neck SOO appeared to be effective for patients with RA. The deformity was corrected and retained for a long time.

BACKGROUND: In recent years, advances in pharmacotherapy for rheumatoid arthritis have dramatically improved the control of disease activity. However, a significant number of patients still develop hand deformity and require surgical reconstruction. The objective of this study was to evaluate the long-term efficacy and drawbacks of the Swanson metacarpophalangeal joint arthroplasty for patients with rheumatoid arthritis over 10 years. METHODS: Clinical and radiological evaluations were performed for 87 joints of 29 hands in 27 patients who underwent metacarpophalangeal joint arthroplasty using the Swanson implant, and who were followed up for an average of 11.4 (10-14) years. RESULTS: The number of operated tender and swollen metacarpophalangeal joints decreased from 24 (27.6%) and 28 (32.2%) to 1 (1.1%) and 2 (2.3%), respectively. The patients' general health and disease activity score 28-erythrocyte sedimentation rate improved at the last survey. Mild recurrence of ulnar drift was observed, but the deformity was generally well-corrected. Implant fracture was noted in eight joints (9.2%), and revision surgery was performed in two joints (2.3%). The average active range of extension/flexion changed from -46.3°/65.9° to -32.3°/56.6°. While a significant change was not noted in grip or pinch strength, patients were satisfied with the operation especially in terms of pain relief and improved hand appearance. CONCLUSIONS: The long-term results of Swanson metacarpophalangeal joint arthroplasty were good in pain relief and correction of deformity, but some problems remain with regard to implant durability and mobility.
RESUMO
OBJECTIVES: The aim is to evaluate the relevance of serum immunoglobulin G (IgG) titres against periodontopathic bacteria to predict the clinical response to 1-year treatment with biological disease-modifying antirheumatic drugs (bDMARDs) in rheumatoid arthritis (RA) patients. METHODS: Data were collected from 50 RA patients who had received conventional synthetic DMARDs, corticosteroids, or non-steroidal anti-inflammatory drugs before (baseline) and after 1-year treatment with bDMARDs in a retrospective cohort study. Changes in rheumatologic conditions were compared between the two groups for low and high baseline IgG titres against Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans according to their median measurements. RESULTS: Twenty-five patients with low anti-P. gingivalis IgG titres showed significantly greater decreases in changes in the Clinical Disease Activity Index and swollen joint count than 25 patients with high anti-P. gingivalis IgG titres (p = .04 for both). Bivariate and multivariate analyses revealed a significantly positive association of baseline anti-P. gingivalis IgG titres with Clinical Disease Activity Index changes (p = .02 and p = .002). However, post-treatment rheumatologic conditions were comparable between 25 patients each in the low and high baseline anti-A. actinomycetemcomitans IgG titre groups. CONCLUSIONS: Baseline serum anti-P. gingivalis IgG titres are predictive of the clinical response to 1-year treatment with bDMARDs in RA patients.

OBJECTIVES: To assess whether periodontitis severity affects the clinical response to biological disease-modifying antirheumatic drugs (bDMARDs) for 1 year in rheumatoid arthritis (RA) patients. METHODS: Data were collected from 50 RA patients who had received corticosteroids, conventional synthetic DMARDs, or non-steroidal anti-inflammatory drugs before (baseline) and after 1 year of bDMARD therapy in a retrospective study. Rheumatologic conditions were compared between the two periodontitis severity groups according to the periodontal inflamed surface area (PISA) or Centers for Disease Control and Prevention (CDC)/American Academy of Periodontology (AAP) case definitions. RESULTS: Twenty-eight patients with no or mild periodontitis showed significantly greater decreases in changes in Clinical Disease Activity Index (CDAI) and tender and swollen joint count in comparison to 22 patients with moderate and severe periodontitis (p = .02, p = .01, and p = .03). Both bivariate and multivariate analyses revealed a significantly positive association between the baseline CDC/AAP definitions and CDAI changes (p = .005 and p = .0038). However, rheumatologic conditions were comparable between 25 patients each in the low and high PISA groups. CONCLUSIONS: Baseline periodontitis severity according to the CDC/AAP definitions is associated with the clinical response to bDMARDs for 1 year in RA patients.

OBJECTIVES: To investigate the outcomes of the modified Thompson-Littler (m-TL) method, a corrective surgical method utilising a dynamic tenodesis, in patients with rheumatoid swan-neck deformity. METHODS: Twenty-seven fingers in 10 patients with rheumatoid arthritis (RA) underwent surgical correction. The mean age at the time of surgery was 60.3 (45-77) years, the mean duration of RA was 19.3 (4-34) years, and the mean postoperative follow-up period was 2.4 (0.5-6) years. RESULTS: The deformity was corrected and the proximal interphalangeal (PIP) joint pain disappeared in all operated fingers. The mean pinch power between the thumb and the operated finger increased. The active extension decreased, the active flexion increased, and the total arc of motion decreased. Comparing the range of motion by Nalebuff's type classification, the postoperative arc of motion decreased as the type advanced. CONCLUSIONS: The m-TL method provided a favourable outcome in cases of Type ≤III rheumatoid swan-neck deformity without severe joint deterioration at the PIP joint. Aesthetic and functional improvements were observed and the patients were satisfied with the operation.
RESUMO
OBJECTIVE: The aim of the present study was to evaluate the association between the periodontal and serological parameters and the disease activity of rheumatoid arthritis (RA) and between the anti-agalactosyl immunoglobulin G (IgG) titer and periodontitis severity. The objective was also to assess the effect of supragingival scaling on the serological parameters in patients with RA. BACKGROUND: The periodontal and serological parameters in relation to the autoimmune inflammatory response have been linked to RA disease activity. However, the association of the anti-agalactosyl IgG titer with RA disease activity and periodontitis severity has not been elucidated. METHODS: The periodontal, rheumatologic, and serological data were collected from 127 patients with RA in a retrospective cohort study. Of the 127 patients, 21 had been randomly assigned to receive oral hygiene instruction and supragingival scaling. The anti-agalactosyl IgG titer was determined by an electrochemiluminescence immunoassay. RESULTS: The patients with a moderate to high RA disease activity showed significantly higher levels of probing depth (PD), clinical attachment level, anti-cyclic citrullinated peptide IgG, and anti-agalactosyl IgG titer and greater mean percentages of severe periodontitis than those with a low RA disease activity (p < .05 for all). Both univariate and multivariate analyses revealed a significantly positive correlation between the PD and RA disease activity (p = .009 and p = .001), between the anti-agalactosyl IgG titer and RA disease activity (p = .002 and p < .001), and between the anti-agalactosyl IgG titer and PD (p < .001 for both). Supragingival scaling significantly decreased the anti-agalactosyl IgG titer (p = 0.03). CONCLUSION: The PD and anti-agalactosyl IgG titer are positively interrelated, both of which are correlated positively with RA disease activity and influenced by supragingival scaling in patients with RA.

OBJECTIVE: Digital joints affected by rheumatoid arthritis often have severe deformity and/or dislocation, and arthrodesis in a functional position is required. METHODS: Arthrodesis was performed using intraosseous wiring (modified Lister's method) from January 2011 to December 2015, and we investigated the union rate, postoperative complications, and patient satisfaction with the operation at the final follow-up. The DASH score, grip power, and pinch power were also investigated before the operation and at the final follow-up. RESULTS: Arthrodesis was performed for 90 digital joints in 56 patients. Bone union was obtained in 85 of 89 joints (96%). Wire removal was needed due to subcutaneous protrusion in 20 joints and superficial infection in five joints. The mean preoperative DASH score of 50.5 improved to 45.2 at the final follow-up. The pulp pinch power of the index fingers through the little fingers changed significantly. In the questionnaire regarding the operated digit using a visual analogue scale (VAS, 0 [worst] to 100 [best]), the overall satisfaction was 70. CONCLUSION: With this approach, we achieved painless stability as well as deformity correction. A restored prehensile pattern and improvement in the activities of daily life can thus be expected after surgery.

OBJECTIVES: This retrospective study aimed to investigate the risk factors associated with delayed wound healing (DWH) after orthopedic surgery in rheumatoid arthritis (RA) patients treated with biological disease-modifying antirheumatic drugs (bDMARDs). METHODS: We reviewed medical records of 276 orthopedic procedures for 187 RA patients treated with bDMARDs. As a preoperative nutritional status assessment, we evaluated body mass index, prognostic nutritional index (PNI), and controlling nutritional status (CONUT). We evaluated DAS28-CRP, DAS28-ESR, face scale, global health, and HAQ-DI to assess the disease activity. Univariate and multivariate logistic regression analyses were performed to evaluate the risk factors for DWH. RESULTS: In 276 procedures, DWH was identified in 24 patients (8.7%). Disease duration, foot and ankle surgery, and preoperative use of tocilizumab were significant in the univariate analyses. These variables were entered into a multivariate model, and it was revealed that preoperative use of tocilizumab and procedures in the foot and ankle were associated with an increased risk of DWH. CONCLUSION: The current retrospective study suggested that preoperative use of tocilizumab and procedures in the foot and ankle were risk factors for DWH.

OBJECTIVES: A pain-free stable wrist is a prerequisite for patients with rheumatoid arthritis to improve their activity of daily life. The present study investigated whether or not radiocarpal arthrodesis yielded good results for more than 20 years. METHODS: A retrospective study was performed on 20 unstable wrists in 17 patients with rheumatoid arthritis. Radiocarpal arthrodesis combined with synovectomy and the Darrach procedure was performed. Wrist pain, grip power, the range of motion, pharmacotherapy, ESR, CRP, and serial radiographs were investigated at the baseline and 20 years after the operation. Patient-reported outcomes using the mHAQ, DASH and patient's satisfaction level were investigated at the final follow-up. RESULTS: Pain had disappeared completely in all patients at 20 years after the operation. The average grip power increased in 16 wrists (80%) and decreased in 4 wrists (20%). Wrist extension and flexion significantly decreased, and supination and pronation remained within the functional range. Radiographically, ulnar shift and palmar subluxation initially improved and remained unchanged for a long time. Fourteen patients (82.4%) with 17 wrists were satisfied with this operation. CONCLUSION: Radiocarpal arthrodesis for rheumatoid wrists provided painless stability for a long period for 20 years or more.

Objectives: We evaluated whether the periodontal inflamed surface area (PISA), a measure of the inflammatory burden posed by periodontitis, is associated with the clinical response to biological disease-modifying antirheumatic drugs (bDMARDs) in patients with rheumatoid arthritis (RA).Methods: We conducted a retrospective study that collected rheumatologic and periodontal data from 54 patients with RA who had received corticosteroid, conventional synthetic DMARDs, or non-steroidal anti-inflammatory drugs before (baseline) and after 6 months of bDMARD therapy. After the patients were divided into two groups based on high or low PISA according to the median measurements at baseline, the rheumatologic condition was compared between the groups.Results: The patients with a low PISA showed significantly lower values for the Clinical Disease Activity Index (CDAI) (p = .008), swollen joint count (p = .02), and patient's and evaluator's global assessment (p = .01 and p = .03) and significantly greater decreases in changes in the CDAI from baseline to 6 months than the patients with a high PISA (p = .01), although these values were comparable at baseline. Both univariate and multivariate analyses revealed a significantly positive correlation between the baseline PISA and changes in the CDAI (p = .04 and p < .001).Conclusion: The PISA is associated with the clinical response to bDMARDs in patients with RA.

Objectives: The aim of this study was to identify the risk factors associated with severe infection in RA patients, with a particular focus on the association of the nutritional status.Methods: We retrospectively analyzed data from 74 patients with RA (male, n = 21; female, n = 53; age 74.2 ± 12.4) admitted to our hospital between 2016 and 2017 for infection (infection group). We also recruited control RA patients (n = 222) who were matched for age, gender and disease duration, with a match ratio of 1:3 (non-infection group). The nutritional condition was assessed based on controlling nutrition status (CONUT) score, and prognostic nutritional index (PNI). The data of the infection group were obtained from the most recent visit prior to the present admission, and non-infection group from the last regular visit in 2017.Results: The respiratory tract was the most frequent site of infection. The BMI and PNI were significantly lower and the CONUT score significantly higher in the infection group than in the non-infection group. A logistic regression analysis revealed that the CONUT score, underlying lung disease and use of prednisolone and biological disease-modifying anti-rheumatic drugs were independent and significant risk factors for serious infection.Conclusion: Poor nutritional status increases the risk of serious infection.

Objectives: To evaluate changes in radiographic findings and plantar pressure distribution after rheumatoid forefoot surgery.Methods: This study was performed on patients with rheumatoid arthritis (RA) who underwent Swanson implant arthroplasty for the 1st metatarsophalangeal (MTP) joint combined with shortening oblique osteotomy at the 2nd through 5th metatarsal necks (group Sw, 55 feet). The following two groups were used as controls: group NS, consisting of 75 feet in RA patients without scheduled forefoot surgery, and group HC, consisting of 24 feet in healthy female subjects. Plantar pressure distribution, and radiographic findings of hallux valgus angle, the angle between the metatarsal bones, talocalcaneal angle, calcaneal pitch angle and calcaneo-first metatarsal angle (CFMA) were measured pre- and one year postoperatively. Peak pressure was measured in nine sections.Results: Calcaneal pitch angle decreased and CFMA increased in group Sw. Peak pressure at the 1st interphalangeal joint (IP) and the 2nd and 3rd MTPs in group Sw decreased, while that at midfoot increased.Conclusion: While the clinical outcome in group Sw was favorable, postoperative longitudinal arch decreased. Postoperative peak pressure at the 2nd through 5th MTPs was comparable with that in group NS; however, it was significantly lower than that in group HC.

OBJECTIVES: To clarify systemic effects of orthopedic surgical intervention in patients with rheumatoid arthritis (RA). METHODS: A prospective observational cohort study was performed in RA patients who were scheduled to have primary elective orthopedic surgeries. Assessments were performed at baseline, 6 and 12 months after surgery using J-HAQ, General Health, EQ-5D, BDI-II, DAS28-CRP(4) and CRP for all registered patients, DASH and grip power for patients with upper-extremity surgeries, TUG for patients with lower-extremity surgeries, and JSSF for patients with ankle and forefoot surgeries. RESULTS: There were 294 sites in 276 patients whose average age was 64 (19-89) years and average disease duration was 16 (1-60) years. Surgical site was shoulder in six patients, elbow in 26, wrist in 74, hand in 63, hip in 13, knee in 50, ankle in 12, and forefoot in 50. In total, physical function (J-HAQ, grip power, DASH, TUG, JSSF), quality of life (J-HAQ, General Health, EQ-5D) and depression (BDI-II) improved and disease activity (CRP, DAS28-CRP(4)) decreased significantly 6 and 12 months after surgery (p<.01), despite some differences in their outcomes by the preoperative disease activity and the surgical site. CONCLUSION: Overall benefits were provided by orthopedic surgical intervention generally in patients with RA.

Methotrexate (MTX) is the first choice disease-modifying antirheumatic drug (DMARD) for rheumatoid arthritis (RA) and is referred to as an "anchor drug"; its use has been steadily increasing annually. However, MTX-related lymphoproliferative diseases (MTX-LPDs) have emerged as important complications in the patients with RA. There have been no reports of intra-articular MTX-LPDs of the patients with RA. Atypical cells were found in the patient's joint fluid by cytological examinations, and MTX-LPDs were suspected. The patient discontinued MTX and open synovectomy was performed. The histological findings and immunohistochemical staining of the specimens confirmed the diagnosis of diffuse large B-cell lymphoma (DLBCL) of MTX-LPDs. After the operation of the patient's left knee joint, pains and swollen joint disappeared with no relapse. The cytological examinations of the synovial fluid followed by knee operation were effective for early diagnosis of MTX-LPD. MTX discontinuation with no chemotherapy followed up with a knee operation improved the recovery of the MTX-LPD.

OBJECTIVES: The intensification of infliximab (IFX) treatment, involving escalation of the dose and shortening of interval, was approved in Japan in July 2009. We consider IFX intensification therapy to be preferable for patients with treatment-resistant active rheumatoid arthritis (RA). We retrospectively compared the efficacy of IFX with that of other bDMARDs in methotrexate (MTX)-resistant patients. METHODS: Patients who satisfied the following criteria were enrolled: (i) those who started bDMARDs between February 2011 and December 2016, and (ii) those who required bDMARDs after 180 d of MTX treatment. We compared 33 patients who had been treated with IFX (IFX group) and 146 who had received other bDMARDs treatment (non-IFX group). RESULTS: IFX was administered at a dose of 6.98 mg/kg/8-week equivalent at 52 weeks. Clinical disease activity index clinical remission (CDAI-CR) was achieved in 49 of the 179 patients at 52 weeks and 13 of these 49 patients received IFX. Logistic regression analysis showed that treatment with IFX was an important variable for the achievement of CDAI-CR at 52 weeks (odds ratio 2.69, 95% confidence interval 1.13-6.42). The severity and frequency of adverse events did not differ. CONCLUSION: Intensification of IFX was effective and well tolerated for MTX resistant patients.

AIM: To investigate the clinical course of patients with elderly-onset rheumatoid arthritis (RA). METHODS: We compared the characteristics, and clinical course of 55 patients who developed RA at over 80 years of age (elderly-onset [EO] group) with 119 patients who developed RA at 40-59 years of age (non-elderly onset [non-EO] group). We also investigated the characteristics and clinical course of 19 patients who developed RA at over 80 and who received biological disease-modifying anti-rheumatic drugs (bDMARDs). RESULTS: The mean DAS28-ESR (DAS) and HAQ-DI (HAQ) of the EO were significantly higher in comparison to the non-EO group (4.91±1.31 vs 4.41±1.47, p=0.043, 1.2±0.9 vs 0.5±0.6, p<0.01). For the first treatment, 87.3% in the EO group received conventional synthetic DMARDs (csDMARDs), none received MTX. The rate of prednisolone (PSL) administration in the EO group was significantly higher than the non-EO group (56.4% vs 30.3%, p<0.01). The DAS and HAQ were significantly decreased in both groups, while the HAQ of the EO group was higher than the non-EO group. The decrease in DAS and HAQ of the PSL users was significantly greater than the non-PSL users (ΔDAS: 2.55±1.83 vs 1.83±1.23, p<0.01, ΔHAQ: 0.9±1.0 vs 0.3±0.6, p=0.027). Among the 19 patients with bDMARDs, the mean DAS and HAQ at baseline were significantly decreased 6 months later. CONCLUSION: Early use of csDMARDs and PSL was effective for functional disability of elderly-onset RA; however, some of them required bDMARDs. Further study should be performed to investigate the effectiveness of the early induction of MTX and bDMARDs.

OBJECTIVE: To compare the influences of tocilizumab (TCZ) and TNF inhibitors (TNFi) on the angiogenesis in synovial tissues of rheumatoid arthritis (RA). METHODS: Synovial tissues were obtained during joint operations from 13 RA patients treated with TCZ for at least 4 months with or without previous use of TNFi, from 13 RA patients with TNFi alone and from 10 RA patients with only conventional synthetic DMARDs (csDMARDs). Synovial tissues were evaluated by hematoxylin and eosin stain as well as by immunohistological staining with anti-CD31 in which the microvessel densities (MVD) were quantitated. Synovial histopathology was scored for various components. RESULTS: The most remarkable change in the synovium with TCZ was reduced angiogenesis as well as degeneration of lining layers irrespective of the previous use of TNFi. Thus, MVD in patients treated with TCZ with or without previous TNFi were significantly decreased compared with those in patients with TNFi alone or with csDMARDs. Moreover, MVD was significantly correlated with lining layer proliferation, but not with synovial stromal proliferation or inflammatory changes. CONCLUSIONS: These results demonstrated that inhibition of angiogenesis is a unique action of TCZ. Moreover, the data also suggest that lining layers proliferation might be closely associated with angiogenesis.

OBJECTIVES: The objective of this study is to clarify the surgical indication for rheumatoid forefoot deformity according to background characteristics and plantar pressure. METHODS: Patients with rheumatoid arthritis were divided into a non-surgical group (group N) and a surgical group (group S). The former consisted of 225 ft, and the latter consisted of 88 ft. DAS28, Japanese Society for Surgery of the Foot rheumatoid arthritis foot and ankle scale (JSSF scale) and hallux valgus angle (HVA) were evaluated as background characteristics. Distribution of peak pressure as plantar pressure was measured in nine sections. RESULTS: In groups N and S, the mean DAS28 was 3.6 and 3.0, the mean JSSF scale was 81.1 and 63.0, and the mean HVA was 19.9° and 35.3°, respectively. The mean peak pressure of group S at the first and third metatarsophalangeal joints was significantly higher compared with group N. Significant differences between the two groups were also seen in Δ pressure (the difference between the maximum and minimum peak pressure values). The cut-off values were 75.0 for JSSF scale, 24.9° for HVA and 3.94 kg/cm2 for Δ pressure. CONCLUSIONS: The combined assessment of HVA and Δ pressure was found to be useful as an indication for surgical treatment of the forefoot.

OBJECTIVES: The objective of this study is to investigate whether ultrasonography (US) images of joints that underwent surgery reflected the synovial histological findings or clinical indicators and to compare the results of the findings related to large joints (LJs) with those of small joints (SJs). METHODS: The operations were performed on 215 joints in 177 patients with rheumatoid arthritis (RA). The 215 joints included 64 LJs and 151 SJs. The joints with the power Doppler (PD) signal grades 0 and 1 were assigned to group L, while those with grades 2 and 3 were assigned to group H. The Rooney score, Disease Activity Score-erythrocyte sedimentation rate (DAS28), serum matrix metallopeptidase 3 (MMP-3), and C-reactive protein (CRP) levels were determined. RESULTS: The Rooney score, DAS28, MMP-3, and CRP levels of the LJs were significantly lower in group L than in group H. In group H, similar results were found in the LJs and SJs, with a significant increase in the disease activity, CRP and MMP-3 levels and the histological findings in comparison to group L. CONCLUSIONS: The PD signal grade was one of the indicators that reflected the degree of synovitis in the histological findings of the active joints of RA patients.
