Filter by:The purpose of this study is to learn how different types of medicines may improve disease activity in people with rheumatoid arthritis (RA). RA is a kind of joint disease that causes pain and swelling. The study will look at data from a large, US-based group of RA patients who have taken the below medicines: - Tofacitinib - Abatacept - Tocilizumab or sarilumab The study will compare clinical disease activity scores of patients on the different medicines taken. The study will also decide whether some patient traits or disease factors play a role in how medicines may improve disease activity.
Comparative effectiveness of different drugs used to treat patients in Rheumatoid Arthritis Saudi database (RASD) Introduction Rheumatoid arthritis (RA) is a chronic inflammatory disease-causing significant disability among patients(1). The prevalence rate of RA varies based on the geographical locations, however, several reviews reported a global prevalence rate of 0.5-1.1% with an annual incidence rate of 20-50 cases per 100 000 of the American and North European population(1,2). Of this population, the World Health Organization reports that 50% will not be able to hold a sustainable job after 10 years of diagnosis . In Saudi Arabia, recent and generalisable epidemiological data regarding RA in Saudi Arabia are limited and suboptimal(1). One study by Al Dalaan et al in 1998, that was conducted in Al-Qassim region reported that the prevalence rate of RA is about 0.2%(3). In patients with RA, early diagnosis was found to halt the ailment's relentless progression to joint destruction which carried a detrimental effect on the patient's functional and psychological state (4). However, the international lag time from the onset of symptoms until the initiation of treatment in patients with RA has been collectively calculated to be around almost one year time (5). Diseases modifying anti rheumatic agents (DMARDS) are the main drugs used for the management of RA, and it mainly reduce the inflammation and improve the outcomes(6). Several DMARSs drugs are available for the management of RA, however, recently, biological DMARDS have also been widely used and recommended in case the conventional DMARDS fail to control the diseases(6,7). Worldwide, there have been multiple studies that examined the effectiveness of DMARDS and bDMARDS drugs for the management of RA, this include large controlled trials which are the gold standard method for investigating medications efficacy(8,9). However, observational real-world data to examine the effectiveness of these medications is also important and can be more generalizable, have longer follow up and can examine different characteristics. Previous observational studies investigating the effectiveness of DMARDS and bDMARDS were mainly in Europe and North America which does not necessarily represent the current situation and the characteristics of the middle eastern population(10,11), as there is so much variability in access to different biological drugs in different countries. In addition, these studies did not compare treatment lines. In the middle east there were limited studies that addressed the effectiveness of different drugs used to treat RA in Saudi Arabia(5,12-14). These studies were mainly cross sectional in nature or reviews, and it is difficult to draw any conclusions with such study designs. Therefore, this research is to compare the effectiveness of multiple DMARDS medication for the treatment of RA patients in Saudi Arabia. Literature Review Rheumatoid arthritis (RA) is a chronic progressive inflammatory disease that causes irreversible joint deformities which can have debilitating effects on a patient's overall wellbeing. RA has a global prevalence rate of 0.5-1.1% with an annual incidence rate of 20-50 cases per 100 000 of the American and North European population (1). Of this population, the World Health Organization reports that 50% will not be able to hold a sustainable job after 10 years of diagnosis. RA is strongly associated with the female gender, with a female to male ratio of 2:1 to 3:1. Smoking habits have also been shown to both increase the risk of acquiring RA and of worsening its prognosis(1,15). Early diagnosis was found to halt the ailment's relentless progression to joint destruction which carried a detrimental effect on the patient's functional and psychological state. A study found that only 31% of RA patients visited a rheumatologist within less than 12 weeks of symptom onset, those who did had ameliorated progression rates at 6 years as measured by the Sharp/van der Heijde score (SHS) as well as higher rates of DMARD-free remission than patients who delayed their presentation to more than 12 weeks (16) Even though the importance of optimal treatment has been demonstrated, in Africa and the Middle East diagnoses are often delayed for months or even years after symptom onset(5,12,17,18) Our group conducted a study in Saudi Arabia showed that patients may not receive a diagnosis of RA for up to 30 months after the onset of symptoms (12). Raising public awareness of RA and treatment options is also an important tool for reducing time to diagnosis(17). Public education programs can lead to earlier diagnosis and initiation of therapy, as observed in patients in the United Arab Emirates(19). Increased public awareness may also lead to patients with symptoms of RA visiting rheumatology clinics rather than other specialties, thereby receiving adequate and timely treatment. Delayed diagnoses can be attributed to a variety of reasons. In
People living with Rheumatoid Arthritis (RA) often present with low muscle mass compared to their healthy counterparts. This affects their mobility, overall health and quality of life. Even though low muscle mass in RA has been recognised for decades, it is still highly prevalent and very little is known about its development, progression, and potential management. The researchers hypothesise that flares of disease activity trigger acute events of muscle wasting due to high inflammation and reduced mobility. This is commonly observed in bed rest studies and people hospitalised for various reasons. If this holds true for RA, it would point towards a stepwise development of RC and potentially allow for time-targeted management of it. A potential method to manage it is through the use of nutritional supplements. Specifically, amino acid supplementation (commonly used by athletes or people wanting to increase muscle mass) during and shortly after a flare may counteract some of the muscle wasting and allow for better long-term mobility and quality of life for people living with RA. This study aims to investigate aspects of muscle health changes following a disease flare-up in people with Rheumatoid Arthritis (RA) and test potential interventions to minimise any such changes. The investigators will randomly assign participants to a standard care or a nutritional supplementation group and assess aspects of body composition, muscle health, disease activity and inflammation on five occasions over a 3-month period.
Prospective, multi-center-observational study conducted within the US, collecting patient samples for research and development to train, test, and validate precision medicine classifiers. These molecular signature response classifiers (MSRC) aim to predict response status to JAK, T-cell, and IL-6 inhibitor therapies in patients with rheumatoid arthritis (RA).
Epidemiological evidence shows that adverse experiences, particularly, but not exclusively in childhood, are predictors of poor long-term health outcomes and certain social domains. In the field of rheumatic diseases, traumatic events, not only in childhood, have been associated with hospitalization, chronic pain, inflammation, worse outcomes, severity of the disease, and mortality. Some mechanisms proposed to explain the association between the experience of adversity and the development of chronic diseases include an impact on the physiology of immune system cells, gene expression due to DNA modification, and cellular senescence. With this background, the investigators wonder if, for patients with rheumatoid arthritis, the presence of adversity understood as a history of violence in childhood and abuse due to suffering from rheumatoid arthritis is associated with markers of cellular senescence and with the severity of illness.
The study will be a multi-center, randomized, open label, parallel trial conducted in rheumatoid arthritis patients treated with glucocorticoids. After signing the informed consent, all patients will be screened as per the inclusion and exclusion criteria. Estimated 314 eligible patients will be enrolled. The enrolled patients will be randomly assigned to either Eldecalcitol group or Alfacalcidol group in a 1:1 ratio and followed up for 12 months. On-site follow up visits will be conducted at Month 6 and 12 after enrollment. The study is designed to evaluate the efficacy and safety of Eldecalcitol in preventing glucocorticoid-induced bone loss in rheumatoid arthritis patients.

Case management (CM) has been recommended as a way of inspiring measurable changes in individual behaviors and improving clinical outcomes for patients with chronic diseases. However, data on its effectiveness for Taiwanese patients with rheumatoid arthritis (RA) are limited. This study aimed to determine the long-term effectiveness of CM that focused on nurses' role among Taiwanese RA patients. A quasi-experimental pre-post test, control-group study with purposive sampling recruited RA patients from a hospital in Taiwan during 2016-2017. CM program was composed of health education sessions and follow-up telephone consultations over a six-month period. A review of medical records and structured questionnaires yielded data about patient demographics and disease characteristics, and included Chinese version of the Arthritis Self-Efficacy Scale and the Taiwanese Depression Questionnaire. A comparison of the long-term effectiveness of the CM program was made using generalized estimating equation. This evidence-based study may be beneficial to characterize the long-term effectiveness of CM for Taiwanese patients with RA, and may be a reference for healthcare providers in facilitating the provision of appropriate interventions to improve the adaptation processes and clinical outcomes for them.
Rheumatoid arthritis (RA) is one of the most frequently occurring autoimmune rheumatic diseases, affecting an estimated 1% of the global population (1). RA is a chronic inflammatory disease that leads to the development of synovial inflammation and effusion, ultimately followed by joint destruction and permanent disability. There is a discrepancy in the understanding of what's of importance when living a life with a chronic disease. The importance of patients' perspectives concerning disease- and treatment related impacts, is of crucial importance when involving patients in decisions about treatment, and to support the patients in optimal medication-taking behaviour to ensure patient health and reduce health care costs. There are still unmet needs that have a huge impact on quality of life (QoL) such as fatigue, pain, sleep and psychological issues, etc, which need to be taken seriously as these can have severe and debilitating consequences for the individual. The aim of this study is to investigate and evaluate the effects of the digital app RheumaBuddy4.1 (RB4.1) and the ability to provide support and increase quality of life in patients with RA
