Elevating the role of carers in rheumatoid arthritis management in the Asia-Pacific region

Aim: Carers may offer valuable insight into the true health status of patients with rheumatoid arthritis (RA). This multinational, multi-stakeholder, exploratory study in Australia, China and Japan aimed to enrich our understanding of the role and potential impact of carers on RA management. Method: This study used a 2-phase sequential mixed methods approach involving 3 key stakeholder groups: rheumatologists, RA patients and carers. The first phase involved an in-depth qualitative exploratory survey (n = 30), which informed the development of the subsequent quantitative validation survey (n = 908). In both phases, patients and carers provided self-assessments of disease and support parameters. Results: In the qualitative phase, patients usually understated the amount of physical support required, compared to carers. Rheumatologists underestimated the amount of physical and emotional care required, compared to carers and patients; however, in the quantitative phase, rheumatologists overestimated the level of support provided by carers. Levels of support provided by carers increased as disease severity increased. Active participation of carers in clinical consultations and treatment decision-making was deemed important by 55% of all patients and 82% of all carers. All stakeholders believed carers’ insights into the physical and emotional conditions of patients were useful and should be considered in clinical decision-making. Over 95% of rheumatologists reported soliciting input from the carer. Conclusion: Carers provide valuable input that can give clinicians greater insight into the patients’ physical and emotional states, and treatment adherence. Development of standardized carer-reported outcomes that correlate with patient-reported outcomes and clinical parameters will ensure clinical meaningfulness and external validity

Efficacy and safety of upadacitinib in patients with psoriatic arthritis: 2-year results from the phase 3 SELECT-PsA 1 study

Introduction: Efficacy and safety of the Janus kinase (JAK) inhibitor upadacitinib (UPA) was evaluated in patients with psoriatic arthritis (PsA) through week 104 of the ongoing long-term extension of the phase 3 trial SELECT-PsA 1. Methods: Exploratory analyses of all primary and secondary endpoints (non-responder imputation and as observed for binary endpoints; mixed-effect model repeated measures and as observed for continuous endpoints), and summary of treatment-emergent adverse events, in patients receiving UPA 15 mg (UPA15) or 30 mg (UPA30) once daily, or adalimumab 40 mg (ADA) every other week, through week 104 are reported. Results: Of 1704 patients, 25.4% discontinued the study drug by week 104. Proportions of patients achieving ≥ 20%/50%/70% improvement in American College of Rheumatology criteria (ACR20/50/70), ≥ 75%/90%/100% improvement in Psoriasis Area and Severity Index (PASI75/90/100), or minimal disease activity (MDA) were maintained through week 104; greater responses by nominal P value were observed with UPA15 and UPA30 versus ADA for ACR20/50/70 and MDA. Mean change from baseline in modified total Sharp/van der Heijde Score (mTSS) was similar across groups and to week 56 results. The safety profile of UPA was generally comparable to ADA and not altered from week 56 data. Rates of serious infection, herpes zoster, anemia, neutropenia, lymphopenia, and elevated creatine phosphokinase remained numerically higher with UPA15 and/or UPA30 versus ADA. Rates of malignancies excluding non-melanoma skin cancer (NMSC), major adverse cardiovascular events, and venous thromboembolism were similar across groups; rates of NMSC were higher with UPA versus ADA. Two deaths were reported with UPA15, one with UPA30, and one with ADA. Conclusions: In PsA patients, efficacy responses were similar or greater with UPA15 or UPA30 versus ADA through week 104, and inhibition of radiographic progression was maintained. No new safety risks were identified with exposure to UPA through 2 years (week 104). Clinical Trial Registration: ClinicalTrials.gov, NCT03104400

Upadacitinib in patients with psoriatic arthritis and an inadequate response to non-biological therapy: 56-week data from the phase 3 SELECT-PsA 1 study

Background: In SELECT-PsA 1, a randomised double-blind phase 3 study, upadacitinib 15 mg and 30 mg were superior to placebo and non-inferior to adalimumab in ≥20% improvement in American College of Rheumatology (ACR) criteria at 12 weeks in patients with psoriatic arthritis (PsA). Here, we report 56-week efficacy and safety in patients from SELECT-PsA 1. Methods: Patients received upadacitinib 15 mg or 30 mg once daily, adalimumab 40 mg every other week for 56 weeks or placebo through week 24 switched thereafter to upadacitinib 15 mg or 30 mg until week 56. Efficacy endpoints included the proportion of patients achieving ≥20%/50%/70% improvement in ACR criteria (ACR20/50/70), ≥75%/90%/100% improvement in Psoriasis Area and Severity Index (PASI75/90/100), minimal disease activity (MDA) and change from baseline in modified total Sharp/van der Heijde Score. Treatment-emergent adverse events per 100 patient years (PY) were summarised. Results: Consistent with results through week 24, ACR20/50/70, PASI75/90/100 and MDA responses were maintained with upadacitinib through week 56 and were generally numerically higher than with adalimumab; inhibition of radiographic progression was also maintained. Patients who switched from placebo to upadacitinib exhibited comparable improvements at week 56 as patients originally randomised to upadacitinib. The rates of serious adverse events were 9.1 events/100 PY with upadacitinib 15 mg and 12.3 events/100 PY with upadacitinib 30 mg. Two deaths were reported in each of the upadacitinib groups. Conclusion: Efficacy across various domains of PsA were maintained with upadacitinib 15 mg and 30 mg through week 56 with no new safety signals observed

Trial of upadacitinib and adalimumab for psoriatic arthritis

Background: The Janus kinase inhibitor upadacitinib is a potential treatment for psoriatic arthritis. The efficacy and safety of upadacitinib as compared with adalimumab, a tumor necrosis factor α inhibitor, in patients who have an inadequate response to nonbiologic disease-modifying antirheumatic drugs are unclear. Methods: In a 24-week, phase 3 trial, we randomly assigned patients in a 1:1:1:1 ratio to receive oral upadacitinib at a dose of 15 mg or 30 mg once daily, placebo, or subcutaneous adalimumab (40 mg every other week). The primary end point was an American College of Rheumatology 20 (ACR20) response (≥20% decrease in the number of tender and swollen joints and ≥20% improvement in at least three of five other domains) at week 12 with upadacitinib as compared with placebo. Secondary end points included comparisons of upadacitinib with adalimumab. Results: A total of 1704 patients received an active drug or placebo. The percentage of patients who had an ACR20 response at week 12 was 70.6% with 15-mg upadacitinib, 78.5% with 30-mg upadacitinib, 36.2% with placebo (P<0.001 for both upadacitinib doses vs. placebo), and 65.0% with adalimumab. The difference between groups for 15-mg upadacitinib as compared with adalimumab was 5.6 percentage points (95% confidence interval [CI], −0.6 to 11.8) and for 30-mg upadacitinib as compared with adalimumab was 13.5 percentage points (95% CI, 7.5 to 19.4). Both upadacitinib doses were noninferior to adalimumab for the ACR20 response at week 12; the 30-mg dose but not the 15-mg dose was superior to adalimumab. The incidence of adverse events through week 24 was 66.9% with 15-mg upadacitinib, 72.3% with 30-mg upadacitinib, 59.6% with placebo, and 64.8% with adalimumab. There were serious infections in 1.2%, 2.6%, 0.9%, and 0.7% of the patients, respectively. Hepatic disorders occurred in 9.1% of patients in the 15-mg upadacitinib group and 12.3% in the 30-mg upadacitinib group, but grade 3 increases in aminotransferase levels occurred in 2% of patients or fewer in all groups. Conclusions: The percentage of patients with psoriatic arthritis who had an ACR20 response at week 12 was significantly higher with 15-mg or 30-mg upadacitinib than with placebo. The 30-mg dose but not the 15-mg dose was superior to adalimumab. Adverse events were more frequent with upadacitinib than with placebo.

Results of the worldwide, cross-sectional ASAS-PerSpA study

Objectives: To characterise peripheral musculoskeletal involvement in patients with spondyloarthritis (SpA) including psoriatic arthritis (PsA), across the world. Methods: Cross-sectional study with 24 participating countries. Patients with a diagnosis of axial SpA (axSpA), peripheral SpA (pSpA) or PsA according to their rheumatologist were included. The investigators were asked which diagnosis out of a list of six (axSpA, PsA, pSpA, inflammatory bowel disease-associated SpA, reactive arthritis or juvenile SpA (Juv-SpA)) fitted the patient best. Peripheral manifestations (ie, peripheral joint disease, enthesitis, dactylitis and root joint disease), their localisation and treatments were evaluated. Results: A total of 4465 patients were included (61% men, mean age 44.5 years) from four geographic areas: Latin America (n=538), Europe plus North America (n=1677), Asia (n=975) and the Middle East plus North Africa (n=1275). Of those, 78% had ever suffered from at least one peripheral musculoskeletal manifestation; 57% had peripheral joint disease, 44% had enthesitis and 15% had dactylitis. Latin American had far more often peripheral joint disease (80%) than patients from other areas. Patients with PsA had predominantly upper limb and small joint involvement (52%). Hip and shoulder involvement was found in 34% of patients. The prevalence of enthesitis ranged between 41% in patients with axSpA and 65% in patients with Juv-SpA. Dactylitis was most frequent among patients with PsA (37%). Conclusion: These results suggest that all peripheral features can be found in all subtypes of SpA, and that differences are quantitative rather than qualitative. In a high proportion of patients, axial and peripheral manifestations coincided. These findings reconfirm SpA clinical subtypes are descendants of the same underlying disease, called SpA.publishersversionpublishe

A cluster analysis in the worldwide ASAS-PerSpA study

Objective To identify clusters of peripheral involvement according to the specific location of peripheral manifestations (ie, arthritis, enthesitis and dactylitis) in patients with spondyloarthritis (SpA) including psoriatic arthritis (PsA), and to evaluate whether these clusters correspond with the clinical diagnosis of a rheumatologist. Methods Cross-sectional study with 24 participating countries. Consecutive patients diagnosed by their rheumatologist as PsA, axial SpA or peripheral SpA were enrolled. Four different cluster analyses were conducted: one using information on the specific location from all the peripheral manifestations, and a cluster analysis for each peripheral manifestation, separately. Multiple correspondence analyses and k-means clustering methods were used. Distribution of peripheral manifestations and clinical characteristics were compared across the different clusters. Results The different cluster analyses performed in the 4465 patients clearly distinguished a predominantly axial phenotype (cluster 1) and a predominantly peripheral phenotype (cluster 2). In the predominantly axial phenotype, hip involvement and lower limb large joint arthritis, heel enthesitis and lack of dactylitis were more prevalent. In the predominantly peripheral phenotype, different subgroups were distinguished based on the type and location of peripheral involvement: a predominantly involvement of upper versus lower limbs joints, a predominantly axial enthesitis versus peripheral enthesitis, and predominantly finger versus toe involvement in dactylitis. A poor agreement between the clusters and the rheumatologist € s diagnosis as well as with the classification criteria was found. Conclusion These results suggest the presence of two main phenotypes (predominantly axial and predominantly peripheral) based on the presence and location of the peripheral manifestations.publishersversionpublishe

加古川市街の農業用水路における貝類の分布と水環境

Habitat distribution of shellfishes were investigated about Semisulcospira libertina(S.L), Cinotania Mstrica(CH) and Corbicula leana(CL) in the two agricultural canals which are neighboring and have same source of stream. As a result of detailed environmental researches, it was found that the habitat distributions of these shellfishes were different considerably between these two canals. We predicted that speed of stream was main factor of this difference. This prediction was supported by a series of experiments by using an experiment waterway of our college. S.L. can inhabit the wide area of agricultural canal because they do not need substratum such as sand and silt, but they can not stay at more than 50cm/s of flow. It was found that C.H. and C.L. need the substratum for their habitation, a 40cm/s of flow becomes the limit for them because substratum begin to drift from this condition. A series of results obtained in the experiments of waterway accorded with the results of field investigations
