ABSTRACT

BACKGROUND: There is limited literature on the prevalence of rheumatologic conditions in Australian First Nations people. Existing evidence suggests a high disease burden with poorer outcomes. In 2016 a rheumatology clinic was established at The Southern Queensland Centre of Excellence in Aboriginal and Torres Strait Islander Primary Health Care (CoE). AIMS: To improve knowledge of rheumatic diseases presentations in an urban First Nations cohort and to assess the effectiveness of the CoE clinic. METHODS: Data on attendance, diagnosis, treatment and demographics were obtained retrospectively from clinical records at the CoE from 2016 to 2020. Administrative attendance data for the largest public general rheumatology clinic in the region for the 4 years preceding the establishment of the CoE clinic were used as a historic cohort control. RESULTS: A cohort of 93 patients was seen at the CoE with 439 appointments compared to 207 in the historical control. Common diagnoses were osteoarthritis (24%), seropositive rheumatoid arthritis (17%), gout (13%) and spondyloarthropathies (10%). Forty per cent of the cohort at CoE were treated with at least one disease-modifying antirheumatic drug (DMARD) and 12% with a biologic or targeted synthetic DMARD. Seventy-five per cent of appointments were attended versus 71% in control group. Adjusted odds ratio of attendance was 1.35 (P = 0.07). CONCLUSIONS: Provision of rheumatology specialty care in an urban primary health setting aimed specifically at the needs of First Nations people led to increased uptake and engagement. A broad range of rheumatologic diagnoses was made and significant DMARD treatments commenced.

ABSTRACT

BACKGROUNDAntigen-specific regulation of autoimmune disease is a major goal. In seropositive rheumatoid arthritis (RA), T cell help to autoreactive B cells matures the citrullinated (Cit) antigen-specific immune response, generating RA-specific V domain glycosylated anti-Cit protein antibodies (ACPA VDG) before arthritis onset. Low or escalating antigen administration under "sub-immunogenic" conditions favors tolerance. We explored safety, pharmacokinetics, and immunological and clinical effects of s.c. DEN-181, comprising liposomes encapsulating self-peptide collagen II259-273 (CII) and NF-κB inhibitor 1,25-dihydroxycholecalciferol.METHODSA double-blind, placebo-controlled, exploratory, single-ascending-dose, phase I trial assessed the impact of low, medium, and high DEN-181 doses on peripheral blood CII-specific and bystander Cit64vimentin59-71-specific (Cit-Vim-specific) autoreactive T cell responses, cytokines, and ACPA in 17 HLA-DRB1*04:01+ or *01:01+ ACPA+ RA patients on methotrexate.RESULTSDEN-181 was well tolerated. Relative to placebo and normalized to baseline values, Cit-Vim-specific T cells decreased in patients administered medium and high doses of DEN-181. Relative to placebo, percentage of CII-specific programmed cell death 1+ T cells increased within 28 days of DEN-181. Exploratory analysis in DEN-181-treated patients suggested improved RA disease activity was associated with expansion of CII-specific and Cit-Vim-specific T cells; reduction in ACPA VDG, memory B cells, and inflammatory myeloid populations; and enrichment in CCR7+ and naive T cells. Single-cell sequencing identified T cell transcripts associated with tolerogenic TCR signaling and exhaustion after low or medium doses of DEN-181.CONCLUSIONThe safety and immunomodulatory activity of low/medium DEN-181 doses provide rationale to further assess antigen-specific immunomodulatory therapy in ACPA+ RA.TRIAL REGISTRATIONAnzctr.org.au identifier ACTRN12617001482358, updated September 8, 2022.FUNDINGInnovative Medicines Initiative 2 Joint Undertaking (grant agreement 777357), supported by European Union's Horizon 2020 research and innovation programme and European Federation of Pharmaceutical Industries and Associations; Arthritis Queensland; National Health and Medical Research Council (NHMRC) Senior Research Fellowship; and NHMRC grant 2008287.

ABSTRACT

AIM: Implementation of treat-to-target (T2T) for rheumatoid arthritis (RA) presents many challenges and an evidence-practice gap has emerged. This study assessed clinician and patient barriers to the implementation of an RA-T2T strategy and developed a knowledge translation (KT) tool for use in "real-life" clinical settings. METHODS: Surveys of patients and rheumatologists measured agreement with RA-T2T recommendations and use in daily practice. Patient knowledge and perceptions were assessed as was clinician willingness to alter practice and barriers to RA-T2T using visual analog scales. An electronic KT-tool was developed and a two-phase usability trial undertaken to assess use in clinical interactions. RESULTS: Ninety-one percent of patients had no prior knowledge of RA-T2T but agreed with the recommendations showing mean level agreement scores (8.39-9.54, SD 2.37-1.54). Ninety percent were willing to try RA-T2T, 49% felt their treatment could be improved and 28% wanted more involvement in treatment decisions. Rheumatologists agreed with RA-T2T recommendations (7.30-9.27, SD 2.59-0.91). Barriers to implementation identified by rheumatologists included time, appointment availability and perceived patient reluctance to escalate medications. Usability experiences with the KT-tool were tracked and clinicians reported it was easy to use (100%), resulted in a discussion of RA-T2T (73%) and a target being set for 63% of consults. Patients reported they read (92%) and understood (87%) the information in the KT-tool, and that a target was set in 62% of interactions. CONCLUSIONS: RA-T2T uptake in clinical practice may be improved through understanding local clinician and patient barriers and an implementation strategy utilizing a patient-driven KT-tool.

ABSTRACT

Background: Telehealth has the potential to improve access to specialist rheumatology services. The timely and appropriate delivery of care to those living with rheumatological diseases is crucial to ensuring excellent long-term outcomes. Introduction: The outcomes of a tele-rheumatology service delivered to regional hospital outpatient clinics were evaluated with patient perspectives and acceptability analyzed. Materials and Methods: A tele-rheumatology clinic was commenced in Australia from a metropolitan hospital to five regional clinics. The model of care included a trained nurse at the spoke site linked to a rheumatologist from the hospital hub site for follow-up consultations of stable review patients using videoconferencing. Surveys assessing perspectives on the tele-rheumatology encounter were completed and a subsample participated in focus groups to further explore acceptability. Results: Forty-eight patients with a diverse range of conditions participated. Patient travel was reduced on average by 95 km and 42% avoided time off work. Eighty-eight to 100% of participants agreed/strongly agreed with statements relating to acceptability, quality of physician-patient interaction, and nurse involvement. Twenty-nine percent expressed the need for a physical examination by a specialist rheumatologist and 25% felt that an in-person consultation would establish better patient-physician rapport. Qualitatively, participants viewed tele-rheumatology as equivalent to in-person care after an initial adjustment period. Discussion: Tele-rheumatology through videoconferencing for follow-up of patients with established disease is acceptable to patients and demonstrates the potential to improve time, travel, and cost burdens placed on patients who live remotely compared with traditional, face-to-face rheumatology care. Conclusions: Implementation of sustainable and patient acceptable models of tele-rheumatology care may allow timely access to all patients living with rheumatological conditions.

ABSTRACT

The Lupus Family Registry and Repository (LFRR) was established with the goal of assembling and distributing materials and data from families with one or more living members diagnosed with SLE, in order to address SLE genetics. In the present article, we describe the problems and solutions of the registry design and biometric data gathering; the protocols implemented to guarantee data quality and protection of participant privacy and consent; and the establishment of a local and international network of collaborators. At the same time, we illustrate how the LFRR has enabled progress in lupus genetics research, answering old scientific questions while laying out new challenges in the elucidation of the biologic mechanisms that underlie disease pathogenesis. Trained staff ascertain SLE cases, unaffected family members and population-based controls, proceeding in compliance with the relevant laws and standards; participant consent and privacy are central to the LFRR's effort. Data, DNA, serum, plasma, peripheral blood and transformed B-cell lines are collected and stored, and subject to strict quality control and safety measures. Coded data and materials derived from the registry are available for approved scientific users. The LFRR has contributed to the discovery of most of the 37 genetic associations now known to contribute to lupus through 104 publications. The LFRR contains 2618 lupus cases from 1954 pedigrees that are being studied by 76 approved users and their collaborators. The registry includes difficult to obtain populations, such as multiplex pedigrees, minority patients and affected males, and constitutes the largest collection of lupus pedigrees in the world. The LFRR is a useful resource for the discovery and characterization of genetic associations in SLE.
