NCT ID: NCT06305936 Recruiting - Clinical trials for Rheumatoid Arthritis

Feasibility Study: Plant Based Diet to Patients With Rheumatoid Arthritis

PLATE
Start date: February 15, 2024
Phase: N/A
Study type: Interventional

In this feasibility study, our primary goal is to assess the practicality of implementing a plant-based food diet intervention for individuals with rheumatoid arthritis (RA). The intervention consists of three key components: 1) Educational materials (videos), 2) Participation in a cooking workshop introducing plant-based meals, complete with recipes, and 3) Daily delivery of plant-based dinner meals over a four-week period. This comprehensive investigation covers the testing of recruitment procedures, randomization, intervention elements, outcome assessments, and participant retention. Adopting a daily plant-based diet involves introducing several new plant-based foods and making adjustments to the existing diets of patients with RA. Consequently, the feasibility study will also aim to explore the acceptability of the intervention and whether a full-scale RCT is practically possible.

Protocol for a Diagnostic Test Accuracy of Histological Muscle and Skin Biopsies of Rheumatoid Arthritis Patients Revealing Objective Chronic Widespread Pain Phenomena Related to Fibromyalgia

Start date: February 7, 2024
Phase:
Study type: Observational

Background: Chronic widespread pain is challenging in the management of the patient with rheumatoid arthritis (RA), affecting approximately one third of this patient population. However, pain is not always caused by disease activity (inflammation) but can be associated to central pain mechanisms as seen in fibromyalgia (FM). FM is characterized by widespread pain and tenderness; often accompanied by disturbed sleep, fatigue, cognitive impairment, emotional distress and multiple symptoms from various organ systems. Among patients with RA the prevalence of concomitant FM is reported to be 12-17% compared to 1-3% in the general population. In general the pain, felt by the fibromyalgia patients is considered to be due to lower pain thresholds because of abnormal central pain processing. Pain reported by RA patients with concomitant FM could potentially be explained by this phenomenon. Little is known about RA patients fulfilling criteria for FM. Muscles-studies of FM patients have not found any histopathological explanation of the pain felt, however an old study of muscle changes in RA patients found changes that could explain muscle pain. Small fiber neuropathy (SFN) is a condition associated with autoimmune diseases, and evidence suggests that SFN is likely to contribute to the pain observed in FM. Objectives: To determine the diagnostic test accuracy (sensitivity and specificity) of both muscle- and skin-biopsies for fibromyalgia phenotyping and detection by clinical referral (RA with concomitant FM) as the reference standard (i.e. fulfilment of 2016 FM criteria). Data collection: Will be done as study subjects are included and stored in REDCAP. Eligibility criteria for participants and settings where the data will be collected: RA patients will be assessed in the daily clinic in Esbjerg and Odense and examined for concomitant FM (I.e. satisfying the 2016 criteria for FM). Patients will afterwards be invited to participate in the study. Inclusion will continue until 25 RA patients fulfilling FM criteria and thus based on the expected prevalence at least 25 (- and maximum 50) RA patients not fulfilling FM critieria has undergone the index tests. Whether participants form a consecutive, random, or convenience series: Participants form a consecutive series. Description of the index test and reference standard: Twenty-five RA patients with concomitant FM and more than 25 (- maximum 50 patients) RA patients not fulfilling FM criteria will undergo the index tests. Muscle and skin biopsies will be performed in each group using standardized techniques. The reference standard will be fulfillment of the 2016 criteria for fibromyalgia. Estimates of diagnostic accuracy and their precision: Regarding muscle- and skin biopsies sensitivity, specificity and positive predictive value will be calculated using two times two table. Regarding skin biopsies, median values in the two groups (RA +/- FM) will be compared using a two-sample t-test.

Predictive Utility of a Short-term Improvement in Objectively Measured Physical Activity in Rheumatoid Arthritis (PUSIPA)

PUSIPA
Start date: September 1, 2023
Phase:
Study type: Observational

SUMMARY Background: Several studies have shown physical activity (PA) to be inversely correlated to disease activity in rheumatoid arthritis (RA) patients. However, it is unclear whether improved PA leads to lower disease activity or if low disease activity predicts improved PA in rheumatoid arthritis patients. Furthermore, it is unknown how fibromyalgia (FM) affects this interaction. Objective(s): Our primary objective will be to compare the effect of an immediate improvement in physical activity after one week on the proportion of RA patients achieving low disease activity after 12 weeks of biological treatment. Furthermore, we will explore whether the presence of concomitant FM affects this clinical response (i.e., interaction between FM status and PA response). Design: A prospective cohort study in the form of a target-trial attempting to address a causal question comparing the outcome among the participants with an immediate improvement in physical activity, relative to individuals without. Setting and patients: Biologically naive RA patients initiating biological treatment are consecutively enrolled. PA is quantified by accelerometry one week prior to, one week after, and after 3 months of biological treatment. Sample size: 100 RA patients starting biological therapy is planned enrolled in the study. Measurements: RA patients will be divided into two groups depending on their improvement in physical activity after onset of biological treatment. The percentage of time spent in moderate-to-vigorously physical activity (MVPA) i.e., the percentage of time a patient is in motion [walking, running, bicycling, or swimming] is measured prior to, one week, and approximately 3 months after biological treatment onset, respectively. The MVPA ratio (MVPA After biological treatment/MVPA Before biological treatment) will divide patients enabling a contrast between two groups: Those with high improvement considering MVPA (after 1 week; the upper tertile of MVPA ratio of the sample) and those without. Treatment response (achieving a disease activity score < 3.2) after approximately 3 months from baseline will be analyzed as the contrast between groups.

NCT ID: NCT06235710 Recruiting - Clinical trials for Rheumatoid Arthritis

Prevalence of Musculoskeletal Complaints in Nursing Home Residents

Start date: January 18, 2024
Phase:
Study type: Observational [Patient Registry]

The goal of this observational study is to investigate the prevalence of joint complaints in nursing home residents with and without dementia. Primary objective: Number of tender or swollen joints. Secondary objectives: 1. Only when it is possible for the nursing home resident to provide us this information: how nursing home residents themselves assess the severity of their joint complaints that day (at that time). If the nursing home resident cannot answer this question (reliably), we use the Pain Assessment Checklist for Seniors with Severe Dementia (PACSLAC-D). 2. Investigate mobility limitations among nursing home residents. 3. To understand whether an accurate (differential) diagnosis for the joint complaints is reported in the electronic files. During the study, a standard physical examination of the musculoskeletal system will performed. Nursing home residents allocated in group 1 (no dementia) also provide an answer on 3 non-incriminating questions (severity of joint complaints, pain in general and general health). Nursing home residents allocated in group 2 (dementia) answer, if possible, 1 non-incriminating question (pain in joints at that moment). These question(s) and the physical examination are also widely used in daily clinical practice. No further incriminating questions or questionnaires will be administered. If the nursing home resident cannot answer this question (reliably), we use the PACSLAC-D.

NCT ID: NCT06231745 Recruiting - Clinical trials for Rheumatoid Arthritis

Paroxetine Safety and Efficacy in Rheumatoid Arthritis

Start date: January 31, 2024
Phase: Phase 3
Study type: Interventional

Rheumatoid arthritis (RA) is a systemic chronic auto-inflammatory disorder which imposes a remarkable burden of morbidity and mortality on global health. The complex interaction between genetics, environment, and immunological response contribute to RA pathogenesis. Current treatment comprises conventional disease-modifying anti-rheumatic drugs (DMARDs) followed by biological DMARDs, if necessary, to achieve low disease activity or remission. Therapeutics used in RA had limitations in tolerability, access, and response duration and magnitude. Consequently, implementation of safe adjunctive treatment for RA is urgently needed to boost the therapeutic response.
