Factors contributing to the improvement in J-HAQ after 3 years of treatment with abatacept in biologic-naïve rheumatoid arthritis patients: Interim results of a long-term, observational, multicentre study in Japan (ORIGAMI).

OBJECTIVES: We investigated the long-term effectiveness, safety, and factors affecting Japanese Health Assessment Questionnaire (J-HAQ) improvement during abatacept treatment in Japanese rheumatoid arthritis (RA) patients. METHODS: The ORIGAMI study is an ongoing observational study of biologic-naïve RA patients with moderate disease activity treated with subcutaneous abatacept (125 mg, once-weekly). Patients treated with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) were extracted from the Institute of Rheumatology, Rheumatoid Arthritis (IORRA) registry as an historical, weighted control group. The primary endpoint for this interim analysis was the proportion of patients with J-HAQ remission (score ≤0.5) at 3 years. RESULTS: Among 279 abatacept-treated and 220 csDMARD-treated patients, J-HAQ remission was achieved at 3 years in 40.5% (95% confidence interval [CI] 34.7%-46.2%) and 28.9% (95% CI 9.9%-47.8%), respectively. Age, RA duration <1 year, baseline J-HAQ score, and Simplified Disease Activity Index remission at 6 months were associated with 3-year J-HAQ remission in the abatacept group. Overall, 24/298 patients (8.1%; safety analysis set) experienced serious adverse drug reactions with an incidence of 5.3 per 100 person-years. CONCLUSIONS: This study confirmed the 3-year effectiveness and safety, and revealed potential factors associated with J-HAQ remission in biologic-naïve RA patients treated with abatacept in real-world clinical practice.

Comparison of effectiveness of methotrexate in patients with late-onset versus younger-onset rheumatoid arthritis: Real-world data from an inception cohort in Japan (NICER-J).

OBJECTIVE: To compare the effectiveness of methotrexate (MTX) as initial therapy in patients with late-onset and younger-onset rheumatoid arthritis (LORA and YORA). METHODS: Of 114 patients with YORA and 96 patients with LORA, defined as RA occurring at ≥65 years of age, enrolled in a multicentre RA inception cohort study, 71 and 66 patients who had been followed up to 6 months after starting MTX treatment were included in this study. RESULTS: Proportions of patients on MTX treatment at 6 months were 96% and 92% in the YORA and LORA groups, respectively. Despite lower doses of MTX in the LORA group compared with the YORA group, no significant difference was observed in clinical disease activity index scores between the two groups throughout the follow-up period. The proportion of patients in clinical disease activity index remission at 6 months was 35% in both groups. Logistic regression analysis revealed that knee joint involvement and high Health Assessment Questionnaire-Disability Index were significant negative predictors of achieving clinical disease activity index remission at 6 months in the LORA group. CONCLUSION: Observations up to 6 months revealed that the effectiveness of MTX administered based on rheumatologist discretion in patients with LORA is comparable to that in patients with YORA in clinical settings.

Patient Sex Is a Significant Factor in Arm Function Recovery After Arthroscopic Rotator Cuff Repair.

Purpose: The purpose of this study was to investigate the impact of patient sex on arm functional recovery after arthroscopic rotator cuff repair (ARCR). Methods: We retrospectively reviewed the clinical records of patients who underwent rehabilitation after ARCR at two affiliated hospitals between January 2014 and December 2019. Patient characteristics included age, sex, type of muscle tear, tear location, muscle strength, Japanese Orthopedic Association (JOA) score, and patient responses to the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire. We used mixed-effects regression models with random intercepts to evaluate the QuickDASH scores, JOA scores, and muscle strength relative to the nonoperated side. Results: Of the 124 patients, 82 (66.1%) were 65-year-old men and 42 (33.9%) were 67-year-old women. The preoperative JOA scores (P = .03) and those at 6 months (P < .001) and 12 months (P = .04) after ARCR were significantly greater for men than for women. QuickDASH scores of men were significantly lower at 24 months (P = .02) and all other time points (P < .001) than those of women. The improvement in QuickDASH scores was significantly higher for women than for men (P < .01). The results of the multiple regression analysis showed that patient sex (95% confidence interval, 0.01-0.45; P < .05) had an impact on QuickDASH scores at 24 months after ARCR. Conclusion: In this study, patient sex was a significant factor affecting the recovery and QuickDASH scores of patients who underwent ARCR. Level of Evidence: Level IV, prognostic case series.

Friend or foe? Inflammation and the foreign body response to orthopedic biomaterials.

The use of biomaterials and implants for joint replacement, fracture fixation, spinal stabilization and other orthopedic indications has revolutionized patient care by reliably decreasing pain and improving function. These surgical procedures always invoke an acute inflammatory reaction initially, that in most cases, readily subsides. Occasionally, chronic inflammation around the implant develops and persists; this results in unremitting pain and compromises function. The etiology of chronic inflammation may be specific, such as with infection, or be unknown. The histological hallmarks of chronic inflammation include activated macrophages, fibroblasts, T cell subsets, and other cells of the innate immune system. The presence of cells of the adaptive immune system usually indicates allergic reactions to metallic haptens. A foreign body reaction is composed of activated macrophages, giant cells, fibroblasts, and other cells often distributed in a characteristic histological arrangement; this reaction is usually due to particulate debris and other byproducts from the biomaterials used in the implant. Both chronic inflammation and the foreign body response have adverse biological effects on the integration of the implant with the surrounding tissues. Strategies to mitigate chronic inflammation and the foreign body response will enhance the initial incorporation and longevity of the implant, and thereby, improve long-term pain relief and overall function for the patient. The seminal research performed in the laboratory of Dr. James Anderson and co-workers has provided an inspirational and driving force for our laboratory's work on the interactions and crosstalk among cells of the mesenchymal, immune, and vascular lineages, and orthopedic biomaterials. Dr. Anderson's delineation of the fundamental biologic processes and mechanisms underlying acute and chronic inflammation, the foreign body response, resolution, and eventual functional integration of implants in different organ systems has provided researchers with a strategic approach to the use of biomaterials to improve health in numerous clinical scenarios.

Choice of and response to treatment in patients with early-diagnosed rheumatoid arthritis: Real-world data from an inception cohort in Japan (NICER-J).

OBJECTIVE: Various guidelines recommend that patients with early rheumatoid arthritis (RA) try to achieve clinical remission within 6 months, and early therapeutic intervention is important to this end. This study aimed to investigate short-term treatment outcomes of patients with early-diagnosed RA in clinical practice and to examine predictive factors for achieving remission. METHODS: Of the 210 patients enrolled in the multicenter RA inception cohort, 172 patients who were followed up to 6 months after treatment initiation (baseline) were included. Logistic regression analysis was used to examine the impact of baseline characteristics on achievement of Boolean remission at 6 months. RESULTS: Participants (mean age, 62 years) initiated treatment after a mean of 19 days from RA diagnosis. At baseline and 3 and 6 months after treatment initiation, proportions of patients using methotrexate (MTX) were 87.8%, 89.0%, and 88.3%, respectively, and rates of Boolean remission were 1.8%, 27.8%, and 34.5%, respectively. Multivariate analysis revealed that physician global assessment (PhGA) (Odds ratio (OR): 0.84, 95% confidence interval (CI): 0.71-0.99) and glucocorticoid use (OR: 0.26, 95% CI: 0.10-0.65) at baseline were independent factors that predicted Boolean remission at 6 months. CONCLUSION: After a diagnosis of RA, satisfactory therapeutic effects were achieved at 6 months after the initiation of treatment centered on MTX according to the treat to target strategy. PhGA and glucocorticoid use at treatment initiation are useful for predicting the achievement of treatment goals.

Feasibility of methotrexate discontinuation following tocilizumab and methotrexate combination therapy in patients with long-standing and advanced rheumatoid arthritis: a 3-year observational cohort study.

OBJECTIVES: Methotrexate (MTX) is associated with extensive side effects, including myelosuppression, interstitial pneumonia, and infection. It is, therefore, critical to establish whether its administration is required after achieving remission with tocilizumab (TCZ) and MTX combination therapy in patients with rheumatoid arthritis (RA). Therefore, the aim of this multicenter, observational, cohort study was to evaluate the feasibility of MTX discontinuation for the safety of these patients. METHODS: Patients with RA were administered TCZ, with or without MTX, for 3 years; those who received TCZ+MTX combination therapy were selected. After remission was achieved, MTX was discontinued without flare development in one group (discontinued [DISC] group, n = 33) and continued without flare development in another group (maintain [MAIN] group, n = 37). The clinical efficacy of TCZ+MTX therapy, patient background characteristics, and adverse events were compared between groups. RESULTS: The disease activity score in 28 joints-erythrocyte sedimentation rate (DAS28-ESR) at 3, 6, and 9 months was significantly lower in the DISC group (P < .05, P < .01, and P < .01, respectively). Further, the DAS28-ESR remission rate at 6 and 9 months and Boolean remission rate at 6 months were significantly higher in the DISC group (P < .01 for all). Disease duration was significantly longer in the DISC group (P < .05). Furthermore, the number of patients with stage 4 RA was significantly higher in the DISC group (P < .01). CONCLUSIONS: Once remission was achieved, MTX was discontinued in patients who responded favorably to TCZ+MTX therapy, despite the prolonged disease duration and stage progression.

Lower limb alignment in healthy Japanese adults.

BACKGROUND: Knowledge regarding the normal alignment of the lower limb is important when considering alignment for total knee arthroplasty. However, few studies have explored the lower limb alignment of healthy Japanese subjects. METHODS: Between July and October 2020, we performed whole leg standing radiography of 120 legs of 60 healthy adult Japanese volunteers aged <50 years in the closed-leg stance. The measurement parameters were hip knee ankle angle (positive for varus), percentage of constitutional varus (hip knee ankle angle ≥ 3°), mechanical axis deviation ratio, mechanical lateral distal femoral angle, medial proximal tibial angle, joint line convergence angle (positive for lateral opening), and tibial joint line angle (positive for medial inclination). RESULTS: The mean measured values for all volunteers, men and women, were as follows: hip knee ankle angle (°), 2.3, 2.6, and 2.0; mechanical axis deviation ratio, 35.8, 35.6, and 36.9; mechanical lateral distal femoral angle (°), 86.7, 87.0, and 86.7; medial proximal tibial angle (°), 85.6, 85.0, and 86.2; joint line convergence angle (°), 0.6, 0.3, and 0.8; and tibial joint line angle (°), -1.0, -0.7, -1.4, respectively. The percentage of constitutional varus was 35.8% overall, 35.8% in men and 35.3% in women. Only the medial proximal tibial angle was smaller in men than that in women (p = 0.003). CONCLUSIONS: The mechanical lateral distal femoral and medial proximal tibial angles were smaller, hip knee ankle angle was larger, and percentage of constitutional varus was higher in Japanese subjects than those reported for subjects in other countries. Our findings improve the understanding of Japanese-specific alignments when considering alignment for lower limb surgery, especially, total knee arthroplasty.

Decennial trends in hip fractures over 20 years in Yamagata Prefecture, Japan.

BACKGROUND: Hip fracture is among the most common injuries in elderly people. We aimed to investigate the decennial trends in hip fractures in patients ≥65 years of age. METHODS: A questionnaire was distributed to all hospitals with a Department of Orthopaedic Surgery in Yamagata Prefecture to collect data on hip fractures occurring in 1996, 2006 and 2016. RESULTS: The response rate was 100%. The total numbers of hip fractures in 1996, 2006 and 2016 were 665, 1169 and 1,728, respectively (crude incidence: 258, 373 and 494 per 100,000 person-year, respectively). Injuries frequently occurred in the early morning and daytime morning in 1996. In contrast, they frequently occurred in activity times (e.g., morning and afternoon) in 2006 and 2016. Among the patients, 80-90% were injured by simple falls, and 70-80% were injured indoors. The incidence of trochanteric fractures was approximately 1.8-1.9 times greater than incidence of neck fractures in all years. Especially, trochanteric fractures in females of ≥90 years of age markedly increased. The rate of surgical treatment was the same in 1996 and 2006, but was lower in 2016. In 1996, the percentage of independent walkers at discharge and 1 year later was almost the same. In 2006 and 2016, the rate of independent walkers was low at discharge, but increased 1 year later. The rate of discharge to home decreased gradually. The combined percentage of patients discharged to home and to rehabilitation institutions in 2006 and the percentage of patients who entered the regional referral clinical pathway in 2016 were both approximately 70%, with no marked changes observed. CONCLUSIONS: Hip fractures, especially trochanteric fractures in super-aged females, increased. Discharge to home decreased, and the use of the regional referral clinical pathway was widespread. Ambulation ability was reduced at discharge, but improved after 1 year.

Evaluation of hindfoot and knee alignment by the hip-to-calcaneus view in patients with knee osteoarthritis and healthy individuals.

BACKGROUND: Hip-to-calcaneus (HC) view is a whole-leg standing view that can visualize the hindfoot in detail. The aim of this study was to investigate the reliability and validity of tibiocalcaneal angle in HC view (H-TCA) by comparing it with that in long axial view (L-TCA). We also verified whether periarticular knee alignment parameters, measured conventionally in whole-leg standing radiography, could be measured in HC view. METHOD: Sixty healthy volunteers and 61 patients with medial knee osteoarthritis were included. H-TCA was measured by two examiners in the healthy group, and intra-class correlation coefficients (ICCs) were evaluated. H-TCA and L-TCA were then measured in the healthy and osteoarthritis groups and correlated. Finally, we measured hip-knee-ankle angle, mechanical axis deviation ratio, mechanical lateral distal femoral angle, medial proximal tibial angle, and joint-line convergence angle in HC view and conventional whole-leg standing radiography to evaluate statistical differences and correlations. RESULTS: The intra-observer and inter-observer ICCs were 0.86 and 0.76, respectively. Correlation coefficients (r) between H-TCA and L-TCA were r = 0.87 in healthy group and r = 0.81 in osteoarthritis group, indicating a strong positive correlation in both groups. There was no significant difference in periarticular knee alignment parameters between HC view and conventional whole-leg radiography. CONCLUSIONS: Hindfoot evaluation in HC view showed high intra-observer and inter-observer reliabilities and strong positive correlation with TCA in long axial view. By using HC view before knee surgery, such as total knee arthroplasty, other necessary alignments can be evaluated simultaneously.

Effectiveness of Bone Marrow-Derived Platelet-Rich Fibrin on Rotator Cuff Healing in a Rabbit Degenerative Model.

BACKGROUND: Platelet-rich fibrin (PRF) is a second-generation platelet concentrate. Although peripheral blood-derived PRF (P-PRF) is commonly applied in biological augmentation, there is no report about the therapeutic effect of bone marrow-derived PRF (BM-PRF) for degenerative rotator cuff tears (RCTs). PURPOSE/HYPOTHESIS: To examine the effects of platelet-rich plasma (PRP), P-PRF, and BM-PRF during rotator cuff repair (RCR) in degenerative RCTs in rabbits. We hypothesized that BM-PRF would accelerate the bone-tendon healing after RCR. STUDY DESIGN: Controlled laboratory study. METHODS: Degenerative RCT models were created 2 weeks before beginning the study, and 68 juvenile rabbits were divided into 4 groups: the control, PRP, P-PRF, and BM-PRF groups. RCR without augmentation was done in the control group. PRP was prepared by centrifuging peripheral blood twice using a plastic tube. P-PRF and BM-PRF were prepared by centrifuging peripheral blood and bone marrow, respectively, using a glass tube. Rabbits from PRP, P-PRF, and BM-PRF groups were administered the augmentation in a similar fashion for RCR, between the rotator cuff and the footprint of the humerus. At 4, 8, and 12 weeks, rabbits were euthanized and histologically assessed using hematoxylin and eosin staining, Alcian blue staining, and immunohistochemical staining for type I and III collagen. The sections were also evaluated with immunofluorescence staining of vascular endothelial growth factor (VEGF) at 4 weeks. RESULTS: The continuity was significantly better in the BM-PRF group at 4 weeks (P < .05). Immunofluorescence staining demonstrated that VEGF-positive stained cells were significantly greater in the BM-PRF group than in the control group (P < .01). The modified tendon maturing score was significantly greater in the BM-PRF group than in the control and PRP groups at 12 weeks (P < .05). There was no significant difference in the modified tendon maturing score of the P-PRF group compared with the control group. CONCLUSION: The rabbit model of degenerative RCTs demonstrated that RCR combined with BM-PRF enhanced tendon-bone continuity and increased the VEGF-positive cells at 4 weeks and obtained preferable tendon-bone maturation at 12 weeks. CLINICAL RELEVANCE: RCR augmented with BM-PRF has the potential to improve clinical outcomes for RCTs.

Progression of Bone and Joint Destruction During the Perinatal Period in Patients With Rheumatoid Arthritis and Juvenile Idiopathic Arthritis in the Last Decade.

BACKGROUND: Rheumatoid arthritis (RA) is a disease that can cause joint destruction and multiple arthritis. We retrospectively investigated bone and joint destruction during the perinatal period in adult patients with RA and juvenile idiopathic arthritis (JIA) in our hospitals in the last decade. METHODS: The study included 15 women, with 20 pregnancies, 19 childbirths, and one fetal death recorded between 2009 and 2018. We analyzed patient characteristics, disease activity, the modified total Sharp score (mTSS), and ΔmTSS from prepregnancy to delivery and from delivery to one year after delivery in the biologics (BIO) group (biologics used before pregnancy) and non-BIO group (not using biologics). RESULTS: There were five preterm births and seven low-birth-weight infants. The Clinical Disease Activity Index (CDAI) before pregnancy and postdelivery worsened from 12±1.8 to 19.9±2.7 (p<0.05). The mTSS at prepregnancy and postdelivery was 47.7±12.2 and 57.3±11.1 in the BIO group, respectively, and 58.9±11.9 and 75.0±13.1 in the non-BIO group, respectively. In addition, the ΔmTSS value from prepregnancy to delivery and from delivery to one year after delivery was 14.5±4.8 and 9.2±1.7 in the BIO group, respectively (p<0.05), and 16.1±5.2 and 8.3±4.0 in the non-BIO group, respectively. CONCLUSION: The disease activity worsened, and bone and joint destruction progressed in both the BIO and non-BIO groups during the perinatal period in adult patients with RA and JIA in the last decade.

Pathogenesis of follicular thymic hyperplasia associated with rheumatoid arthritis.

Lymphoproliferative disorders may occur in patients with rheumatoid arthritis (RA) who are treated with methotrexate. However, follicular thymic hyperplasia (FTH) associated with RA (FTH-RA) is generally not considered a lymphoproliferative disorder. To investigate the pathogenesis of FTH-RA, we examined 12 cases of FTH involving thymic enlargement, four of FTH involving RA and eight of FTH involving myasthenia gravis (MG). Increased numbers and larger germinal center (GC) size were observed in FTH-RA group. The percentage of distorted GCs was 13.3% in FTH-RA group and 3.25% in FTH associated with MG (FTH-MG) group. A greater meshwork of follicular dendritic cells was observed in the GCs of FTH-RA group. Positive indices of CD27+ cells and PD-1+ cells per GC in FTH-RA group were significantly higher than those in FTH-MG group, though positive indices of CD68+ cells and CD163+ cells were similar. Myoid cell proliferation, as evaluated by α-SMA, tenascin-C, and l-caldesmon expression, was significantly increased in the FTH-RA group compared with the FTH-MG group. These results suggest that FTH should be considered in patients with RA treated with methotrexate. The pathogenesis of FTH-RA includes GC expansion and increased numbers of memory B cells, follicular helper T cells, and myoid cells, indicating humoral immunity activation.

Infectious sacroiliitis due to group A streptococcus infection during pregnancy: a case report.

BACKGROUND: Group A streptococcus infection during pregnancy can be concerning. It may cause toxic shock syndrome, which can be fatal. Here, we report a rare case of a pregnant woman who developed infectious sacroiliitis due to group A streptococcus infection. To the best of our knowledge, this case is the first of its kind to be reported. CASE PRESENTATION: A 32-year-old multiparous Japanese woman presented with fever and right buttock pain at 28 weeks of gestation. Based on our clinical findings and investigations, she was diagnosed with group A streptococcus bacteremia and infectious sacroiliitis caused by group A streptococcus. A cardiotocography performed to assess the fetal status showed fetal tachycardia. To prevent the patient from progressing to toxic shock syndrome caused by group A streptococcus, we performed an emergency cesarean section. The patient and her infant had a good course after the cesarean section. CONCLUSION: A pregnant woman diagnosed with group A streptococcus infection needs to be monitored closely because a timely decision to deliver the fetus before rapid deterioration to toxic shock syndrome is crucial.

Assessment of the severity of curly toe.

BACKGROUND: Curly/underlapping toe involves flexion, adduction, and varus deformity of the interphalangeal joints. There are no previous reports showing the relationship between physical examination and X-ray findings among patients with curly toe deformity. METHODS: We investigated the clinical findings of 116 consecutive patients associated with 239 underlapping toes. We compared the age and affected toes between patients whose deformities were pointed out at a pediatric medical examination (group 1) and those referred for medical treatment (group 2). The degree of curly toe deformity was graded by a physical examination and X-ray. RESULTS: The average age at presentation was 2.7 years. The affected toes were significantly different between groups 1 and 2 (p < .001). The morbidity of each toe differed significantly in group 2 (p < .005) but not in group 1. The correlation between the appearance grading and classification by X-ray was very strong using Spearman's rank correlation coefficient. The severity of curly toe was divided into mild in 104 toes, moderate in 105 toes, and severe in 17 toes. The methods of conservative treatment were observation only in 15 cases, manipulations in 30 cases, taping in 67 cases, and a brace in 9 cases. Surgery was performed in 8% of cases. CONCLUSION: Curly toe deformity of the third or fourth toes tend to be referred for medical treatment because of the abnormality. Our grading system using a physical examination and classification by X-ray was useful for assessing the severity of curly toe.

Effectiveness and safety of subcutaneous abatacept in biologic-naïve RA patients at Week 52: A Japanese multicentre investigational study (ORIGAMI study).

OBJECTIVES: To evaluate the effectiveness and safety of abatacept over 52 weeks in biologic-naïve rheumatoid arthritis (RA) patients with moderate disease activity in the prospective, 5-year, observational study (ORIGAMI study) in Japan. METHODS: Abatacept (125 mg) was administered subcutaneously once a week. Clinical outcomes included Simplified Disease Activity Index (SDAI) remission at Week 52 (primary endpoint), Japanese Health Assessment Questionnaire (J-HAQ), EuroQol 5-Dimension Questionnaire (EQ-5D), treatment retention, and safety. The results were compared with those of conventional synthetic disease-modifying antirheumatic drug (csDMARD) controls from the ongoing Institute of Rheumatology, Rheumatoid Arthritis (IORRA) registry. RESULTS: Overall, 325 patients were enrolled, with a mean age of 66.9 ± 12.7 years. The proportion of patients achieving SDAI remission (≤3.3) at Week 52 was 18.9% (95% CI: 14.3-23.6) and low disease activity (≤11) was 53.3% (95% CI: 47.4-59.1). A significant improvement was observed in J-HAQ and EQ-5D over 52 weeks in both the abatacept and csDMARD groups. The probability of abatacept treatment retention at Week 52 was 69.9% (95% CI: 64.7-75.5). Adverse events and serious adverse events were reported in 50.0% and 12.1% of patients, respectively. CONCLUSIONS: Abatacept significantly improved disease activity, physical disability, and quality of life for up to 52 weeks in RA patients in a real-world setting.

Forefoot Deformities in Patients with Rheumatoid Arthritis: Mid- to Long-Term Result of Joint-Preserving Surgery in Comparison with Resection Arthroplasty.

BACKGROUND: Joint-preserving surgery for the forefoot has been increasingly performed for rheumatoid arthritis (RA). We compared joint-preserving surgeries with resection arthroplasty for RA in the forefoot. METHODS: Forefoot surgeries were performed on 62 toes in 42 patients with RA (men: 2; women: 40) between 2002 and 2018. Three groups were compared: PP-31 toes treated with joint-preserving surgery involving the modified Mann method for the big toe and offset osteotomy for lesser toes, PR-15 toes treated with joint-preserving surgery for the big toe and resection arthroplasty for lesser toes, and RR-16 toes treated with resection arthroplasty for all the toes. RESULTS: The PP group had significantly higher mean scores on a scale for RA in the foot and ankle at the latest follow-up than the RR group (86 vs. 75 points; p < 0.05). Hallux valgus (angle > 20°) of the big toe at the latest follow-up recurred in 10 (32%), 9 (60%), and 16 (100%) patients in the PP, PR, and RR groups, respectively. A revision surgery was performed in one patient each in the PP and PR groups. CONCLUSIONS: Joint-preserving surgery is superior to resection arthroplasty in preventing function loss and the recurrence of hallux valgus.

Patient satisfaction, preferences, expectations, characteristics, and impact of suboptimal control of rheumatoid arthritis: A subgroup analysis of Japanese patients from a large international cohort study (SENSE).

OBJECTIVE: To evaluate treatment satisfaction, disease outcomes, and perspectives of patients with poorly controlled rheumatoid arthritis (RA) treated with conventional synthetic, targeted synthetic, or biologic disease-modifying antirheumatic drugs (DMARDs), we conducted a subgroup (post hoc) analysis of Japanese patients participating in the SENSE study. METHODS: Data for Japanese patients (n/N = 118/1629) from the global, multicenter, cross-sectional, observational SENSE study were analyzed. The primary endpoint was the global satisfaction subscore assessed using the Treatment Satisfaction Questionnaire for Medication (TSQM) version 1.4. Other patient-reported outcomes included self-reported RA medication adherence and Work Productivity and Activity Impairment-RA. Patient perspectives included patients' expectations and preference of pharmacologic treatment. RESULTS: Median (range) age and RA disease duration were 67.0 (18.0-87.0) years and 8 (0.0-54) years, respectively; 81.4% of patients were female. Mean (SD) TSQM global satisfaction subscore was 56.8 (17.5), and only 5.9% of patients reported good satisfaction with treatment (TSQM global ≥80). Mean (SD) self-reported treatment adherence using VAS was high (93.5% [13.8%]). Mean (SD) total work productivity impairment was 45.6% (32.0%); presenteeism contributed toward more total work productivity impairment (43.9% [30.4%]) than absenteeism (8.3% [24.4%]). Patients expected improvement in all parameters from their treatment, especially improvement in joint symptoms. Most patients (80.7%) preferred oral medication and 18.7% preferred monotherapy. Patient acceptability of potentially manageable side effects was high (7.5%-34.0%). Although most patients (81.3%) found combination therapy acceptable, 43.2% were receiving DMARD monotherapy. CONCLUSION: Although most Japanese patients with RA with moderate-to-high disease activity were dissatisfied with their current DMARD treatment, high treatment adherence, high acceptability of combination therapy, high acceptability of manageable potential side effects, and preference for oral medication were reported. Data support the development of a more individualized and patient-centric approach for RA treatment.

Differences in subtrochanteric and diaphyseal atypical femoral fractures in a super-aging prefectural area: YamaCAFe Study.

INTRODUCTION: Atypical femoral fractures (AFFs) have been correlated with long-term use of bisphosphonates (BPs), glucocorticoids (GCs), and femoral geometry. We investigated the incidence and characteristics of subtrochanteric (ST) and diaphyseal (DP) AFFs in all institutes in a super-aging prefectural area. MATERIALS AND METHODS: We performed a blinded analysis of radiographic data in 87 patients with 98 AFFs in all institutes in Yamagata prefectural area from 2009 to 2014. Among the 98 AFFs, 57 AFFs comprising 11 ST fractures in 9 patients and 46 DP fractures in 41 patients with adequate medical records and X-rays were surveyed for time to bone healing and geometry. RESULTS: Of the 87 patients, 67 received BPs/denosumab (77%) and 10 received GCs (11%). Surgery was performed in 94 AFFs. Among 4 AFFs with conservative therapy, 3 required additional surgery. In univariate regression analyses for ST group versus DP group, male-to-female ratio was 2/7 versus 1/40, mean age at fracture was 58.2 (37-75) versus 78 (60-89) years, rheumatic diseases affected 55.5% (5/9) versus 4.9% (2/41), femoral lateral bowing angle was 1.7 (0-6) versus 11.8 (0.8-24)°, GC usage was 67% (6/9) versus 4.9% (2/41), and bone healing time was 12.1 (6-20) versus 8.1 (3-38) months (p < 0.05). In multivariate analyses, higher male-to-female ratio, younger age, greater proportion affected by rheumatic diseases, and higher GC usage remained significant (p < 0.05). CONCLUSIONS: The incidence of AFFs in our prefectural area was 1.43 cases/100,000 persons/year. This study suggests that the onset of ST AFFs have greater correlation with the worse bone quality, vice versa, the onset of DP AFFs correlated with the bone geometry. The developmental mechanisms of AFFs may differ significantly between ST and DP fractures.
