RESUMO
CASE: Three cases of inflammatory joint diseases (systemic lupus erythematosus and ongoing juvenile idiopathic arthritis) with painful flexible progressive collapsing foot deformity (PCFD) underwent flatfoot surgery. All cases maintained sufficient radiological correction and achieved good clinical condition at final follow-up. CONCLUSION: Although the prospect for recurrence of the deformity is not clear, even in inflammatory joint diseases, flat foot surgery such as flexor digitorum longs transfer, spring ligament reconstruction, and lateral column lengthening could have a possibility to be indicated against PCFD, as long as disease activity could be well suppressed by drug therapy, subsequently subtalar and talonavicular joints could be preserved.

OBJECTIVE: We explored the relationship between achievement of clinical disease control and improvements in and normative values for patient-reported outcomes (PROs), including quality of life (QoL) measures, in patients with psoriatic arthritis (PsA). METHODS: This was a post hoc analysis of 104-week data from the SELECT-PsA 1 and 2 trials in adults with PsA and inadequate response to one or more conventional synthetic (SELECT-PsA 1) or biologic (SELECT-PsA 2) disease-modifying antirheumatic drug. Patients were initially randomized to upadacitinib 15 mg once daily (QD) to placebo switched to upadacitinib 15 mg QD at week 24 or to adalimumab 40 mg every other week (SELECT-PsA 1 only), and data were pooled across treatments and analyzed. We evaluated several clinical disease control measures (minimal disease activity [MDA]; very low disease activity [VLDA]; and low disease activity [LDA] and/or remission by Disease Activity in Psoriatic Arthritis [DAPSA], Psoriatic Arthritis Disease Activity Score [PASDAS], and Routine Assessment of Patient Index Data 3 [RAPID3]) and examined their associations with improvements and normative values for various PROs. RESULTS: A total of 1,069 and 317 patients were analyzed for SELECT-PsA 1 and 2, respectively. In both studies, responders (patients who achieved MDA or VLDA, and DAPSA, PASDAS, and RAPID3 LDA or remission) at week 104 achieved more marked changes from baseline, and more responders achieved normative values in PROs compared with nonresponders (most nominal P < 0.0001). Furthermore, numerically larger proportions of responders achieved minimal clinically important differences across PROs compared with nonresponders in both studies. In addition, patients who achieved MDA or VLDA were more likely to achieve DAPSA, PASDAS, and RAPID3 LDA or remission (all nominal P < 0.0001) for upadacitinib 15 mg QD and when treatment arms were pooled. CONCLUSION: Patients with PsA who achieve clinical disease control are more likely to achieve improvements and normative values in PROs and QoL measures, which reinforces disease control as a treatment target.
RESUMO
PURPOSE: This study proposes a process for detecting slices with bone marrow edema (BME), a typical finding of axSpA, using MRI scans as the input. This process does not require manual input of ROIs and provides the results of the judgment of the presence or absence of BME on a slice and the location of edema as the rationale for the judgment. METHODS: First, the signal intensity of the MRI scans of the sacroiliac joint was normalized to reduce the variation in signal values between scans. Next, slices containing synovial joints were extracted using a slice selection network. Finally, the BME slice detection network determines the presence or absence of the BME in each slice and outputs the location of the BME. RESULTS: The proposed method was applied to 86 MRI scans collected from 15 hospitals in Japan. The results showed that the average absolute error of the slice selection process was 1.49 slices for the misalignment between the upper and lower slices of the synovial joint range. The accuracy, sensitivity, and specificity of the BME slice detection network were 0.905, 0.532, and 0.974, respectively. CONCLUSION: This paper proposes a process to detect the slice with BME and its location as the rationale of the judgment from an MRI scan and shows its effectiveness using 86 MRI scans. In the future, we plan to develop a process for detecting other findings such as bone erosion from MR scans, followed by the development of a diagnostic support system.
RESUMO
OBJECTIVE: It is known that fracture risk is increased in patients with psoriatic arthritis (PsA), however, there is no consensus on the association with osteoporosis. The purpose of this study was to elicit the rate of osteoporosis and the risk factors of osteoporosis in patients with PsA at our institution. METHODS: The data in this study were extracted from 163 patients with PsA. Osteoporosis and osteopenia were defined based on the WHO definition. Osteoporosis was also diagnosed when a fragility vertebral compression fracture was observed. RESULTS: The osteoporosis and osteopenia rates for PsA patients were 11.7% and 33.1%, respectively. The rates of osteoporosis and osteopenia in males were particularly high compared to previous reports, at 9.3% and 34.3%, respectively. Trabecular bone score (TBS) was considered age-appropriate for both males and females. Body mass index (BMI) and TBS were significantly lower in patients with osteoporosis. CONCLUSIONS: In patients with PsA, males are at elevated risk of osteoporosis and associated fragility fractures even if they are under 50 years old. BMI was significantly lower in osteoporotic cases, suggesting the importance of bone mineral density testing and treatment in such cases.
RESUMO
The concept of pustulotic arthro-osteitis (PAO) was first reported by Sonozaki et al. in 1979, with diagnostic criteria (Sonozaki criteria) proposed in 1981. These criteria have served as the gold standard for PAO diagnosis for over 40 years. In recent years, there has been an increasing emphasis on maximizing the quality of life of patients with PAO. This is achieved by striving for clinical remission, structural remission, and functional remission through early diagnosis and appropriate therapeutic intervention from an early stage. This article is an English translation of a summary of the 'Modified PAO Diagnostic Guidance 2022', edited by the Japan Ministry of Health, Labour and Welfare's Research Group on improvement of medical standard and quality of life of patients with spondyloarthritis and related diseases represented by ankylosing spondylitis and the Japan Spondyloarthritis Society. This guidance is intended to be helpful to both Japanese and global communities in rheumatology and spondyloarthritis.

BACKGROUND: According to the conventional postoperative procedure after total ankle arthroplasty (TAA) against end-stage osteoarthritis (OA) and rheumatoid arthritis (RA), mobilization and weight-bearing is currently started after completion of wound healing. Recently, early mobilization for dorsiflexion after TAA with modified antero-lateral approach was reported to be feasible and safe. To investigate the further possibility of expediting rehabilitation, this study evaluated the feasibility and safety of early full weight-bearing and gait exercise after cemented TAA utilizing a modified antero-lateral approach. MATERIALS AND METHODS: This retrospective, observational study investigated 23 consecutive ankles (OA: 14 ankles, RA: 9 ankles) that had received cemented TAA with a modified antero-lateral approach. These ankles were divided into three groups [1. conventional postoperative protocol: 8 ankles, 2. early dorsiflexion protocol: 7 ankles, 3. early dorsiflexion+full weight-bearing protocol: 8 ankles]. In group 3, after early dorsiflexion mobilization (day 3), full weight-bearing/gait exercise was started from 7 days after surgery (10 days after if malleolar osteotomy was added). Postoperative wound complications were observed and recorded. Number of days for hospitalization was also evaluated. Range of motion (ROM) of dorsiflexion/plantar flexion was measured. Patients also completed a self-administered foot evaluation questionnaire (SAFE-Q) and the scale of Japanese Society for Surgery of the Foot (JSSF) ankle/hindfoot score preoperatively and at final follow-up. RESULTS: No postoperative complications related to wound healing were observed even after early full weight-bearing and gait exercise. Days for hospitalization was significantly shortened in early full weight-bearing and gait exercise group (group 3) from 35-38 days to 24 days. ROM for both dorsiflexion and plantar flexion significantly increased in group 3, furthermore all indices of SAFE-Q score also showed stronger significant improvement in group 3. JSSF score improved significantly after TAA in all groups. CONCLUSION: Within this small number of cases, early full weight-bearing and gait exercise from 7 days after cemented TAA was feasible and safe with the modified antero-lateral approach. Combination of early dorsiflexion mobilization and weight-bearing/gait exercise contributed to shortening the hospitalization day, and improving ROM for both dorsiflexion and plantar flexion after surgery. Innovations in postoperative procedures for rehabilitation after TAA can be expected.
RESUMO
Pustulotic arthro-osteitis (PAO) is an infrequent condition, with its manifestation in children being even rare. Some reports propose an association between genetic variants and the onset of PAO. Currently, no definitive treatment protocol exists for paediatric patients with PAO. In this study, we present the paediatric case of PAO with an IL36RN variant who was successfully treated with tonsillectomy.

OBJECTIVE: While biologics have been used for the patients with psoriatic arthritis, there remains to be unknown concerning long-term retention rates. This study aims to present real-world data about long-term retention rates of biologics for the patients with psoriatic arthritis, and to undertake an analysis of the contributing factors. METHODS: We examined retention rates and the reasons for discontinuation for biologics (adalimumab, certolizumab pegol, secukinumab, and ixekizumab) in 146 prescriptions (of which, 109 prescriptions were as naive) at our hospital since March 2010. RESULTS: Throughout the entire course of the study, the 10-year retention rates were approximately 70% for adalimumab, 50% for ixekizumab, and 40% for secukinumab. When evaluating retention rates in the biologic-naïve subgroups, the 10-year retention rates were all approximately 70%. Regarding certolizumab pegol, the 3-year retention rate was approximately 75%. For adalimumab, a higher degree of arthritis at the initiation of treatment was found to correlate with an increased likelihood of secondary inefficacy. The main reason for discontinuation was secondary inefficacy, except for ixekizumab. CONCLUSIONS: Each biologic exhibited a favourable long-term retention rate. The main reason for discontinuation was secondary inefficacy. Regarding adalimumab, secondary inefficacy was linked to the extent of arthritis upon treatment initiation.

Although biologics have their own characteristics, there are no clear criteria for selecting them to treat the patients with rheumatoid arthritis. To assist in selecting biologics, we investigated the retention rates of biologics at our institution. We examined retention rates, and reasons for dropout for biologics in 393 cases and 605 prescriptions (of which 378 prescriptions were as naive) at our hospital since October 2003. Throughout the entire course of the study, etanercept (ETN) was the most frequently used biologic, followed by adalimumab (ADA) and tocilizumab (TCZ). When narrowed down to the later period from 2010, ETN was still the most used, followed by TCZ and abatacept (ABT). When the retention rates were compared in biologic naive patients, the retention rates were TCZ, ABT, ETN, certolizumab pegol (CZP), golimumab (GLM), infliximab (IFX), and ADA, in that order. The retention rates were better with the first use of each biologic. The main reasons for dropout were primary ineffectiveness, secondary ineffectiveness, and infection. ETN was the most used biologic in our hospital, with an increasing trend toward the use of non-TNF inhibitors. Retention rates were higher in non-TNF inhibitors.

BACKGROUND: The combination of distal osteotomy with lateral dissection in joint-preserving surgery for severe hallux valgus deformity has recently begun to yield encouraging results. We examined the frequency of complications and risk factors of those for joint-preserving surgery in patients with and without rheumatoid arthritis (RA). METHODS: A retrospective, observational study of 72 feet (27 patients with RA) was performed. The inclusion criteria were patients who underwent joint-preserving surgery for hallux valgus deformity at our hospital between January 2008 and March 2016 who could be followed up with for longer than 12 months. RESULTS: The mean preoperative and immediate postoperative hallux valgus angles (HVA) were 41.8 and 4.4, respectively. The mean preoperative and immediate postoperative intermetatarsal angles between the first and second metatarsal bones (M1-M2A) were 14.6 and 5.8, respectively. At the final postoperative evaluation, the mean HVA was 8.8 and the mean M1-M2A was 6.4.Data were compared among the patients with complications (recurrent valgus deformity, varus deformity), and those without complications (normal HVA) at the final postoperative evaluation. The rate of RA in the varus deformity group was 71.4%, which tended to be higher than in other groups (p = .058). The mean preoperative HVA were 48.2 and 52.6 in the group of recurrent valgus deformity and varus deformity, which was higher than the normal HVA group (p = .001). CONCLUSIONS: High preoperative HVA was a risk factor for the recurrence of valgus deformity. Most of the varus deformities were observed in the RA group with high preoperative HVA; therefore, caution should be exercised in operating on patients with severe deformity or those with RA. LEVEL OF EVIDENCE: III.

INTRODUCTION AND IMPORTANCE OF THE CASE: This is the first report of subcutaneous emphysema of the thigh as a complication after total knee arthroplasty (TKA). PRESENTATION OF CASE: A 78-year-old female patient with valgus knee arthropathy underwent TKA. Two days postoperatively, the patient experienced left thigh swelling and pain, and subcutaneous emphysema was detected upon palpation. Although the skin tone was comparable to the other side, the left thigh was tender and firm. The surgical wound did not exhibit erythema. Computed tomography imaging revealed emphysema in the subcutaneous and intermuscular regions of the left thigh. Gram stain and culture tests from arthrocentesis were negative, and blood culture results were also negative. As there was no fever or disturbance of consciousness, and the LRINEC score was 1, supportive care was provided to the patient. At 5 days postoperatively, there was an observable improvement in the emphysema, and by day 9 postoperatively, the emphysema had fully resolved. CLINICAL DISCUSSION: There is a lack of documented cases reporting extensive subcutaneous emphysema of the thigh following TKA, suggesting it to be an exceedingly rare complication. In this case, we conducted a thorough investigation to assess the potential association of infection. Subsequently, the symptoms were successfully alleviated with supportive care without antibiotics. CONCLUSION: The occurrence of subcutaneous emphysema in the thigh was identified as a postoperative complication following TKA. Blood tests, culture tests and LRINEC score can be valuable tools for differentiation.
RESUMO
OBJECTIVES: To assess the long-term safety and efficacy of upadacitinib in patients with psoriatic arthritis (PsA) and an inadequate response (IR) to biologic disease-modifying anti-rheumatic drugs (bDMARDs) who completed up to 152 weeks of treatment in the SELECT-PsA 2 study (ClinicalTrials.gov: NCT03104374). METHODS: Patients were randomised to receive blinded upadacitinib 15 or 30 mg once daily (QD), or placebo for 24 weeks followed by upadacitinib 15 or 30 mg QD. After 56 weeks, patients were eligible to enter an open-label extension (OLE) in which they continued their assigned dose of upadacitinib. Efficacy and safety were assessed through 152 weeks. A subanalysis of patients with IR to tumour necrosis factor inhibitors (TNFis) was also conducted. RESULTS: In total, 450 patients entered the OLE and 358 completed 152 weeks of treatment. Improvements in efficacy outcomes observed at week 56, including the proportion of patients achieving: 20/50/70% improvement in American College of Rheumatology criteria, minimal disease activity, and 75/90/100% improvement in Psoriasis Area and Severity Index, were maintained through week 152. Efficacy outcomes in the TNFi-IR subgroup were similar to those reported in the overall population. Upadacitinib was well tolerated throughout long-term treatment, with no cumulative adverse effects observed through 152 weeks. CONCLUSIONS: Efficacy of upadacitinib was maintained up to 152 weeks of treatment in this highly treatment-refractory population of patients with PsA. The long-term safety profile of upadacitinib 15 mg was consistent with its known safety profile across indications; no new safety signals were identified.

OBJECTIVES: Since inflammation can cause joint destruction in patients with rheumatoid arthritis (RA), it is assumed that joints that are symptomatic at onset are at higher risk of joint destruction; however, this theory remains controversial. This study aimed to investigate whether the progression of joint destruction in hands and feet could be predicted from the clinical and radiographic findings at onset. METHODS: This study included 75 patients who visited our hospital within one year after the onset of RA with at least 12 months of follow-up. We examined the positive predictive value (PPV) and the sensitivity of the clinical findings (swelling, tenderness, and squeeze test) and joint destruction at onset for the progression of joint destruction. RESULTS: Sixty joints (45 metacarpophalangeal and proximal interphalangeal joints, 15 metatarsophalangeal joints) exhibited progressive structural destruction during the study course. Both the PPV and the sensitivity of the clinical findings for the progression of joint destruction were low; however, only the sensitivity of the squeeze test for the feet was high. The PPV of joint destruction at onset was higher than the clinical findings, and the sensitivity of joint destruction at onset was as high as the squeeze test for the feet. Conclusions: Regular follow-up with imaging is necessary regardless of symptoms and joint destruction at the onset. Adding the squeeze test for feet to routine clinical practice may help predict the risk of joint destruction for the feet.
RESUMO
BACKGROUND: According to the conventional postoperative procedure after total ankle arthroplasty (TAA), mobilization is currently started after completion of wound healing. To investigate the possibility of expediting rehabilitation, this study evaluated the feasibility and safety of early mobilization of dorsiflexion after cemented TAA utilizing a modified antero-lateral approach. MATERIALS AND METHODS: This retrospective, observational study investigated 14 consecutive ankles that had received cemented TAA. Mobilization of dorsiflexion was started from 3 days after surgery. Postoperative wound complications including blister formation, eschar formation, wound dehiscence, peri-incisional decreased sensation were observed and recorded. Range of motion (ROM) of dorsiflexion/plantar flexion was measured. Patients also completed a self-administered foot evaluation questionnaire (SAFE-Q) and the scale of Japanese Society for Surgery of the Foot (JSSF) ankle/hindfoot score preoperatively and at final follow-up. RESULTS: No postoperative complications related to wound healing were observed. ROM for dorsiflexion, SAFE-Q score, and JSSF score improved significantly after TAA. CONCLUSION: Within this small number of cases, early mobilization of dorsiflexion from 3 days after cemented TAA was feasible and safe with the modified antero-lateral approach. Innovations in postoperative procedures for rehabilitation after TAA can be expected.
RESUMO
Pustulotic arthro-osteitis (PAO) is a rare chronic inflammatory arthropathy associated with palmoplantar pustulosis. The pathogenesis of PAO remains unclear. The most common musculoskeletal involvement in PAO is ossification of the sternoclavicular joints. A combination of parietal inflammation and hyperostosis-induced mechanical compression in this region is hypothesized to contribute to multiple venous thrombosis. Here, we present a 66-year-old man with PAO-associated multiple venous occlusion who was successfully treated with guselkumab. We also discuss its clinical manifestation and cause by reviewing the literature.

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.
RESUMO
Although concurrent occurrence of spondyloarthritis (SpA) and ulcerative colitis (UC) is sometimes seen, the profiles of cytokines have been poorly understood in UC-associated SpA. We herein report a case of UC-associated SpA successfully treated with infliximab (IFX). Profiles of cytokines in the serum and colonic mucosa were characterized by an enhanced expression of IL-6 but not tumor necrosis factor (TNF)-α. Successful induction of remission by IFX was associated with the downregulation of IL-6 expression but no significant alteration in TNF-α expression. These findings suggest that some cases of UC-associated SpA might be driven by IL-6, and IFX might be effective in cases lacking enhanced TNF-α responses.

This study investigated modified scarf osteotomy as a salvage procedure after resection arthroplasty or silicone implant arthroplasty to preserve mobility of the first metatarsophalangeal (MTP) joint after hallux valgus surgery in patients with rheumatoid arthritis (RA). We investigated three feet with rheumatoid forefoot deformities that showed recurrence of forefoot deformity or breakage of the implant after resection or silicone implant arthroplasty in the first MTP joint. All feet were treated using modified scarf osteotomy with capsular interposition. All cases achieved obvious correction after modified scarf osteotomy despite resection of the first MTP joint and consequently showed both radiographic and clinical improvements. Modified scarf osteotomy offers potential as a definitive salvage procedure after resection arthroplasty or silicone implant arthroplasty for forefoot deformity in patients with RA, because the procedure can realign the first MTP joint obviously with preservation of the range of motion. Concomitant medial capsular interposition into the newly formed first MTP joint is also recommended where possible, to protect the edges of the proximal basal phalanx and distal first metatarsal and also to smoothen the motion of newly formed first MTP joint.

OBJECTIVE: To investigate the influence of nutritional status on severe infection complications in patients with rheumatoid arthritis (RA). METHODS: This retrospective cohort study on 2108 patients with RA evaluated the prognostic nutritional index (PNI) as an index of nutritional status. Patients were classified into the high or low PNI group according to the cutoff PNI value (45.0). Based on propensity score matching analysis, 360 patients in each group were selected for comparing the incidence of serious infection, clinical findings, and PNI scores. RESULTS: The incidence of infection was significantly higher in the low PNI group than in the high PNI group (p < 0.001). The occurrence rate of infectious complication at 104 weeks was significantly higher in the low PNI (<45.0) group than in the high PNI group (p < 0.001). The incidence of infection was particularly high in elderly patients (≥65 years) with a low PNI, but the incidence in elderly patients with a high PNI was similar to that in nonelderly patients with a high PNI. CONCLUSIONS: Patients with RA and malnutrition had a higher incidence of severe infection; thus, evaluating and managing nutritional status is necessary for the appropriate and safe treatment of elderly patients with RA.

CASE: Marked varus or valgus hindfoot deformities in 3 patients with ankle osteoarthritis or rheumatoid arthritis were treated by corrective surgery using total ankle arthroplasty or distal tibia oblique osteotomy. All cases achieved not only sufficient correction and satisfactory clinical/radiographic hindfoot improvement but also improvements in both knee alignment and function. CONCLUSION: Corrective surgery for hindfoot deformity can potentially change or improve ipsilateral knee alignment and function, representing an unexpected benefit of hindfoot realignment.
