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.

Tumor Response Predicts Survival Time of Nivolumab Monotherapy for Advanced Gastric Cancer: A Subgroup Analysis of the DELIVER Trial (JACCRO GC-08).

BACKGROUND: This prospective observational study evaluated the real-world effectiveness of nivolumab monotherapy in previously treated advanced gastric cancer (GC). A preplanned 2-year final analysis was performed to confirm survival and tumor behavior with nivolumab monotherapy. PATIENTS AND METHODS: The primary endpoint was overall survival (OS). The data regarding tumor size were prospectively collected and evaluated using the RECIST criteria. Exploratory analyses were performed for survival according to the tumor response and depth of response (DpR) in patients with measurable lesions who were receiving nivolumab monotherapy as third- or later-line therapy. RESULTS: In 487 patients, the median OS and progression-free survival (PFS) were 5.8 (95% CI 5.3-6.9) months and 1.8 (95% CI 1.7-2.0) months, respectively. The response rate (RR) was 14.5% in 282 patients with measurable lesions. In 234 patients treated with third- or later-line, the DpR was found to be associated with PFS and OS in the Spearman analysis (r = 0.55 and 0.44, respectively) as well as using a discrete variable. When the DpR was divided into 5 groups (-20%≥DpR; -20%

Effects of the abacus-based mental calculation training application "SoroTouch" on cognitive functions: A randomized controlled trial.

This study investigated the effect of a home-based computerized cognitive training program that utilizes a digital application for training abacus-based mental calculations, "SoroTouch," on the cognitive functions of healthy middle-aged and older people using a randomized controlled trial. The participants were 20 adults (aged 42-79 years) who were involved in community-based activities for dementia prevention held by a certain organization. The participants were assigned randomly to the intervention (SoroTouch) group or control group. The SoroTouch group received home-based cognitive training with SoroTouch, being asked to use the software every day for 6 months, while the control group did not receive any intervention. To investigate the effect of SoroTouch, CogEvo, a cognitive functions test battery utilizing a tablet device, was administered to all participants once per month during the 6-month intervention period. In addition, before and after the intervention, all participants were asked to take the CogEvo and the Japanese version of the Montreal Cognitive Assessment (MoCA-J). The analyses showed that the SoroTouch group did not improve total scores of the CogEvo and MoCA-J, but large group differences were observed in the two tasks of the CogEvo as follows: 'Follow the order' (modified Trail Making Test) at 2 months after the beginning of the intervention (group differences; 39.4, 95% confidence interval; 7.6-71.2) and 'Route 99' at 6 months (group differences; 39.6, 95% confidence interval; 4.9-74.4). These results provide evidence that a home-based computerized cognitive training program SoroTouch has the potential to improve working memory, attention and planning in healthy middle-aged and older adults.

Self-controlled Case Series Study for Acute Kidney Injury after Starting Proton Pump Inhibitors or Potassium-Competitive Acid Blocker in Patients with Cancer Using a Large Claims Database.

To investigate the risk of acute kidney injury (AKI) in patients with cancer following the initiation of proton pump inhibitors (PPIs) and potassium-competitive acid blocker (PCAB), considering sex and anti-cancer drug use. We conducted a self-controlled case-series study using the Japan Medical Data Center claims data from 12422 patients with cancer who were prescribed PPIs or PCAB between January 2017 and December 2019. Considering the timing of PPI or PCAB, control period (days -120 to -1), risk period 1 (days 0 to +30), and risk period 2 (days +31 to +365) were defined. To assess the incidence rate ratio (IRR) and 95% confidence interval (CI) as the risk ratio, we adjusted for anti-cancer drugs to assess the risk of AKI. Additionally, we also examined sex differences to identify the risk of AKI. AKI was observed in risk period 1 [2.05 (1.12-3.72), p = 0.0192], but a slight reduction was noted in risk period 2 [0.60 (0.36-1.00), p = 0.0481]. A sex-specific increase in the risk of AKI was observed only in males during risk period 1 [2.18 (1.10-4.32), p = 0.0260], with a reduction in risk period 2 [0.48 (0.26-0.89), p = 0.0200]. We identified an increased risk of AKI in patients with cancer starting PPIs or PCAB particularly in males within 30 d after PPI or PCAB initiation, emphasizing the need for vigilant monitoring and management of AKI in this patient population.

Risk of flare and damage accrual after tapering glucocorticoids in modified serologically active clinically quiescent patients with systemic lupus erythematosus: a multinational observational cohort study.

OBJECTIVES: To assess the risk of flare and damage accrual after tapering glucocorticoids (GCs) in modified serologically active clinically quiescent (mSACQ) patients with systemic lupus erythematosus (SLE). METHODS: Data from a 12-country longitudinal SLE cohort, collected prospectively between 2013 and 2020, were analysed. SLE patients with mSACQ defined as the state with serological activity (increased anti-dsDNA and/or hypocomplementemia) but without clinical activity, treated with ≤7.5 mg/day of prednisolone-equivalent GCs and not-considering duration, were studied. The risk of subsequent flare or damage accrual per 1 mg decrease of prednisolone was assessed using Cox proportional hazard models while adjusting for confounders. Observation periods were 2 years and censored if each event occurred. RESULTS: Data from 1850 mSACQ patients were analysed: 742, 271 and 180 patients experienced overall flare, severe flare and damage accrual, respectively. Tapering GCs by 1 mg/day of prednisolone was not associated with increased risk of overall or severe flare: adjusted HRs 1.02 (95% CI, 0.99 to 1.05) and 0.98 (95% CI, 0.96 to 1.004), respectively. Antimalarial use was associated with decreased flare risk. Tapering GCs was associated with decreased risk of damage accrual (adjusted HR 0.96, 95% CI, 0.93 to 0.99) in the patients whose initial prednisolone dosages were >5 mg/day. CONCLUSIONS: In mSACQ patients, tapering GCs was not associated with increased flare risk. Antimalarial use was associated with decreased flare risk. Tapering GCs protected mSACQ patients treated with >5 mg/day of prednisolone against damage accrual. These findings suggest that cautious GC tapering is feasible and can reduce GC use in mSACQ patients.

Unincreased mortality of patients with early rheumatoid arthritis compared to the general population in the past 17 years: Analyses from the IORRA cohort.

OBJECTIVES: The aim of this article is to investigate the mortality rate of patients with early rheumatoid arthritis (RA) over the past 17 years. METHODS: Japanese patients with early RA enrolled in the Institute of Rheumatology, Rheumatoid Arthritis cohort from 2001 to 2012 were classified into Groups A (2001-06) and B (2007-12). The standardized mortality ratio (SMR) and 5-year survival rate were calculated. RESULTS: Groups A and B had 1609 and 1608 patients, of which 167 and 178 patients were lost during follow-up and 47 and 45 deaths were confirmed, respectively. The SMR (95% confidence intervals) for Groups A and B were 0.81 (0.59-1.08) and 0.78 (0.57-1.04), respectively, with the condition that all untraceable patients were alive. Assuming that the mortality rate of untraceable patients was twice as high as that of the general population, the SMR was 0.90 (0.68-1.19) for Group A and 0.92 (0.68-1.23) for Group B. The 5-year survival rates were 96.9% and 97.0% for Groups A and B, respectively. CONCLUSIONS: The 5-year mortality of patients with early RA has been comparable to that of the general Japanese population. The 5-year survival rate has been stable over the past 17 years.

Associations of disease duration and anti-citrullinated peptide antibody status with the effectiveness of abatacept in biologic-naïve patients with rheumatoid arthritis: Post hoc analysis of a multicentre, real-world observational study in Japan (ORIGAMI).

OBJECTIVES: The aim of the article is to investigate the associations of disease duration and anti-cyclic citrullinated peptide antibody (ACPA) status with the effectiveness of abatacept in biologic-naïve patients with rheumatoid arthritis (RA). METHODS: We performed post hoc analyses of the Orencia® Registry in Geographically Assembled Multicenter Investigation (ORIGAMI) study of biologic-naïve RA patients aged ≥20 years with moderate disease activity who were prescribed abatacept. Changes in the Simplified Disease Activity Index (SDAI) and Japanese Health Assessment Questionnaire (J-HAQ) at 4, 24, and 52 weeks of treatment were analysed in patients divided according to ACPA serostatus (positive/negative), disease duration (<1/≥1 year), or both. RESULTS: SDAI scores decreased from baseline in all groups. SDAI scores tended to decrease more in the ACPA-positive group and disease duration <1-year group than in the ACPA-negative group and disease duration ≥1-year group, respectively. In the disease duration <1-year group, SDAI tended to decrease more in the ACPA-positive group than in the ACPA-negative group. Disease duration was independently associated with the change in SDAI and SDAI remission at Week 52 in multivariable regression models. CONCLUSIONS: These results suggest that starting abatacept within 1 year of diagnosis was associated with greater effectiveness of abatacept in biologic-naïve patients with RA and moderate disease activity.

Impact of interstitial lung disease on clinical remission and unfavourable events of rheumatoid arthritis: results from the IORRA cohort.

OBJECTIVES: We aimed to examine the impact of concomitant interstitial lung disease (ILD) on achieving clinical remission and the occurrence of unfavourable clinical events in patients with RA. METHODS: Among the participants in the Institute of Rheumatology, Rheumatoid Arthritis (IORRA) cohort from 2011 to 2012, patients not achieving remission of 28-joint disease activity score (DAS28) at baseline and those with chest CT images were enrolled. Based on the chest CT images, the patients were divided into two groups: the ILD group and non-ILD group. The associations among the presence of ILD with time to achieving DAS28 remission and development of death, hospitalized infection, major adverse cardiac events (MACE), or malignancy within 5 years were evaluated using time-dependent Cox regression models. RESULTS: We enrolled 287 patients in the ILD group and 1235 in the non-ILD group. DAS28 remission was achieved at least once in 55.7% and 75.0% of the ILD and non-ILD groups within 5 years, respectively. Presence of ILD was significantly associated with failure to achieve DAS28 remission (adjusted hazard ratio [aHR]: 0.71; 95% CI: 0.58, 0.89). ILD was also a significant factor associated with death (aHR: 3.24; 95% CI: 2.08, 5.03), hospitalized infection (aHR 2.60; 95% CI: 1.77, 3.83), MACE (aHR: 3.40; 95% CI: 1.76, 6.58), and lung cancer (aHR: 16.0; 95% CI: 3.22, 79.2), but not with malignant lymphoma (aHR: 2.27; 95% CI: 0.59, 8.81). CONCLUSION: Concomitant ILD was a significant factor associated with failure to achieve clinical remission and the occurrence of the unfavourable clinical events in patients with RA.

Intravenous immunoglobulin treatment for obstetric antiphospholipid syndrome refractory to conventional therapy: A single-arm, open-labelled multicentre clinical trial.

OBJECTIVES: The objective of the study was to compare the efficacy of intravenous immunoglobulin (IVIG) therapy for obstetric antiphospholipid syndrome (APS) refractory to conventional treatment. METHODS: We conducted a single-arm, open-label multicentre clinical intervention trial. The enrolled criteria were patients with refractory APS who had a history of still or premature birth before 30 weeks of gestational age, even though they had been treated with conventional treatment, i.e. heparin and low-dose aspirin. After confirming the foetal heartbeats, a single course of IVIG (0.4 g/kg body weight daily for 5 days) was added to conventional treatment. The primary outcome was a live birth ratio of >30 weeks of gestational period, and the secondary outcome included improving pregnancy outcomes compared to previous pregnancy. RESULTS: Twenty-five per cent of patients (2 of 8 cases) achieved a live birth after the 30th week of pregnancy by IVIG-only add-on treatment, which is the same prevalence as the historical control. However, by adding other second-line therapy to IVIG and conventional treatment, further three patients (37.5%) achieved improvements in pregnancy outcome compared to previous treatments. In total, five patients (62.5%) were able to achieve preferable pregnancy outcomes through combination treatment including IVIG. CONCLUSIONS: This clinical trial could not demonstrate the efficacy of IVIG-only add-on therapy at improving the pregnancy outcomes of patients with obstetric APS refractory to conventional treatment. However, the combination of IVIG with rituximab or statins adding to conventional treatment improved pregnancy outcomes and resulted in more live births. Further studies are needed to investigate the efficacy of multi-targeted therapy to treat obstetric refractory APS.

Evaluation of levator ani muscle elasticity after vaginal delivery and cesarean section using shear wave elastography.

PURPOSE: The risk of pelvic floor muscle injury is commonly considered to be higher in vaginal than in cesarean delivery. This study aimed to compare levator ani muscle (LAM) elasticity after vaginal and cesarean delivery using shear wave elastography (SWE). METHODS: Postpartum women who underwent a single SWE evaluation 1 month after their first delivery were divided into vaginal and cesarean delivery groups. The elastic moduli of both sides of the LAM were measured in a horizontal section and compared between the groups. In addition, a subgroup analysis was performed to compare LAM elasticity according to the delivery method within the vaginal delivery group-normal vaginal delivery, episiotomy, and operative vaginal delivery. RESULTS: Sixty-two women were included (vaginal delivery, n = 47; elective cesarean section, n = 15). Multiple regression analysis revealed that the LAM elastic modulus was significantly lower in the vaginal delivery group than in the cesarean delivery group (right LAM: 44.2 vs. 72.7 kPa, p = 0.0036; left LAM 40.4 vs. 82.7 kPa, p < 0.0001). In the subgroup analysis, the right LAM elastic modulus was significantly lower in the operative vaginal delivery subgroup than in the normal vaginal delivery subgroup (p = 0.0131). However, there was no significant difference in the left LAM elastic modulus between the three subgroups. CONCLUSION: LAM elasticity was significantly lower after vaginal delivery than after cesarean delivery. Furthermore, the elasticity of the right LAM was lower after operative vaginal delivery than after normal vaginal delivery. SWE has the potential to provide an objective quantitative assessment of postpartum pelvic floor muscle recovery.

Factors associated with sarcopenia in Japanese patients with rheumatoid arthritis: results from the IORRA cohort study.

To investigate the prevalence of and factors associated with sarcopenia in Japanese patients with rheumatoid arthritis (RA). We analyzed a cross-section of patients with RA participating in the Institute of Rheumatology Rheumatoid Arthritis cohort survey in 2021. Participants completed self-administered questionnaires, including a 5-item sarcopenia screening index (SARC-F). Patients with a SARC-F score of 4 or higher were categorized as having sarcopenia. Among 2416 Japanese patients with RA (2113 women and 303 men; mean age 63.9 years), 341 (14.1%) patients were categorized as having sarcopenia. In a multivariable analysis of patients of all ages, age, body mass index (BMI), disease duration, history of fracture, patient pain on a visual analog scale (VAS), patient or physician global assessments based on VAS, and use of nonsteroidal anti-inflammatory drugs (NSAIDs), biologic disease-modifying antirheumatic drugs (bDMARDs), and corticosteroids were significantly (P < 0.05) associated with sarcopenia. Disease duration, patient global assessments based on VAS, and use of NSAIDs and bDMARDs were significantly associated with sarcopenia among the patients aged < 65 years, whereas age, female sex, BMI, disease duration, history of fracture, patient pain VAS and global assessments based on VAS, and use of bDMARDs and corticosteroids were significantly associated with sarcopenia in patients aged ≥ 65 years. In Japanese patients with RA, age, BMI, disease duration, history of fracture, patient pain VAS and global assessments based on VAS, and use of NSAIDs, bDMARDs, and corticosteroids were associated with sarcopenia. Among older patients with RA, female sex was additionally associated with sarcopenia. Key Points • To our knowledge, this is the first report showing factors associated with sarcopenia in Japanese patients with rheumatoid arthritis using a large cohort database. • Age, BMI, disease duration, history of fracture, patient pain on a visual analog scale, and use of nonsteroidal anti-inflammatory drugs, biologic disease-modifying antirheumatic drugs, and corticosteroids were associated with sarcopenia in Japanese patients with rheumatoid arthritis. Limited to elderly patients, female sex was also associated with sarcopenia.

Soluble PD-L1 changes in advanced non-small cell lung cancer patients treated with PD-1 inhibitors: an individual patient data meta-analysis.

Introduction: Currently, first-line immune checkpoint inhibitors (ICIs), including programmed cell death protein-1 (PD-1) inhibitors, are utilized as monotherapy in advanced non-small cell lung cancer (NSCLC) patients with high programmed death ligand-1 (PD-L1) expression (≧50%). Pre-treatment or post-treatment serum soluble PD-L1 (sPD-L1) has been identified as a potential biomarker for assessing ICI efficacy through fixed-point observations. However, existing studies on sPD-L1 changes have produced inconsistent results or have had sample sizes too small to detect clinically meaningful effect sizes. To elucidate the role of sPD-L1, we conducted a collaborative individual patient data meta-analysis of PD-1 inhibitor treatments. Methods: We conducted a thorough search of articles in PubMed via Medline, Embase, Scopus, and Cochrane databases from inception to October 20, 2023. Trials were deemed eligible if they contained individual datasets for advanced NSCLC patients, including data on overall survival (OS)/progression-free survival (PFS), as well as pre- and post-treatment sPD-L1 levels after 3-4 cycles of PD-1 inhibitor treatments. Our analysis focused on patients who completed 3-4 cycles of PD-1 inhibitor treatments. The primary outcome measure was OS/PFS, and we assessed changes in sPD-L1 concentration pre- and post-treatment through ELISA analyses. Results: From our search, we identified a potential seven trials, encompassing 256 patients. Among these, two trials with 26 patients met the criteria for inclusion in our primary analyses. Over a median follow-up period of 10 months, pooled univariate analysis revealed that increases in sPD-L1 levels during PD-1 inhibitor treatment were not associated with OS (HR = 1.25; CI: 0.52-3.02)/PFS (HR = 1.42; CI: 0.61-3.30) when compared to cases with sPD-L1 decreases. Subgroup analyses indicated that the impact of sPD-L1 changes on overall mortality/progression-related mortality remained consistent regardless of gender, age, or the type of treatment (nivolumab or pembrolizumab). Conclusion: Our findings suggest that changes in sPD-L1 levels during PD-1 inhibitor treatment do not significantly influence the prognosis of advanced NSCLC patients, regardless of gender, age, or treatment type. Continuous monitoring of sPD-L1 may not offer significant advantages compared to fixed-point observations.

Contribution of the factors to EuroQol 5 Dimensions in rheumatoid arthritis patients achieving low disease activity/remission with abatacept treatment: post-hoc subgroup analyses of the Japanese real-world observational "ORIGAMI" study.

OBJECTIVES: To address improvements in quality of life (QOL), we analysed the relative contributions of factors to EuroQol 5 Dimensions (EQ-5D) in abatacept-treated rheumatoid arthritis (RA) patients in the ORIGAMI study. METHODS: Patients who were evaluable for disease activity through to Week 52 in the ORIGAMI study were divided into those achieving Simplified Disease Activity Index-remission/low disease activity (remission/LDA; n=178) and patients with moderate/high disease activity (MDA/HDA; n=99). We compared the changes in EQ-5D and other outcomes through to Week 52. Focusing on the remission/LDA group, the contribution of each factor to the variance of EQ-5D at baseline and Week 52 was examined using analysis of variance. RESULTS: The remission/LDA group showed greater improvements than the MDA/HDA group in EQ-5D, Japanese Health Assessment Questionnaire, visual analogue scale for pain (Pain VAS), and patient global assessment (PtGA). In the remission/LDA group, factors significantly contributing to EQ-5D were sex, C-reactive protein, and Pain VAS at baseline, and PtGA and age at Week 52. CONCLUSIONS: In RA patients who achieved remission/LDA during abatacept treatment, PtGA and age at Week 52 contribute to the variance of EQ-5D, suggesting that identification of factors associated with PtGA may be important to address improvements of QOL.

Randomized trial of advice from healthcare professionals to eliminate constriction by maternal clothing on the trunk to prevent preterm birth and improve health status.

AIM: Women's clothing during pregnancy may influence perinatal outcomes. A preliminary study suggested that midwives' advice to avoid wearing tight clothing during pregnancy may reduce the risk of preterm delivery. We examined the effects of such advice to pregnant women on the risk of preterm birth and health status during pregnancy. METHODS: An open-label evaluator-blinded randomized controlled trial was conducted at the National Centre for Child Health and Development in Tokyo, Japan. Normal pregnant women were randomly assigned to receive constrictive clothing elimination care or standard care at 20 weeks gestation. The control group was issued leaflets concerning anemia prevention at entry and skin care at 30 weeks' gestation, along with a brief explanation and answers to questions by midwives as standard care. The intervention group received advice from midwives concerning avoiding constrictive clothing in addition to standard care. The primary outcome was the incidence of preterm birth (<37 weeks). The secondary outcomes were 12 indicators related to preterm delivery or health status. RESULTS: Among 624 randomly assigned women, 599 (intervention group, n = 306; control group, n = 293) completed the study between February 2015 and August 2016. The incidence of preterm birth in the intervention and control groups was 4.2% (13/306) and 5.1% (15/293), respectively (p = 0.614). There were no significant differences regarding any secondary outcomes, including obstetric outcomes and physical/mental indicators, during pregnancy. CONCLUSIONS: Advice from midwives to avoid constrictive clothing during pregnancy did not influence the incidence of preterm birth or maternal health status.
