Monitoring Epstein-Barr Virus (EBV) Load in Rheumatoid Arthritis Patients Treated With New Immunosuppressive...
Rheumatoid ArthritisPBMNC DNA is considered a limit above which patients will develop EBV associated post transplant lymphoproliferative disorder. we showed that methotrexate tended to decrease EBV load over time, but this did not reach significance and that TNFa inhibitors did not significantly modify EBV load over time. Our objective is to monitor Epstein Barr Virus load over time in patients with Rheumatoid arthritis under Orencia* (abatacept) or RoActemra* (tocilizumab), to detect possible immunosuppression associated EBV dysregulation, as seen in post transplant lymphoproliferative disease.
Cost of Care for Juvenile Idiopathic Arthritis
Juvenile Idiopathic ArthritisThis project seeks to collect data on healthcare utilization and expenditure rates in Juvenile Idiopathic Arthritis (JIA) patients from across the US, correlate these costs with disease activity and outcome measures and determine methods by which to reduce the economic impact while improving outcomes.
Genetics of Rheumatoid Arthritis
Rheumatoid ArthritisThis study attempts to identify the genes responsible for rheumatoid arthritis (RA), or inflammation of the joints. It is known that genes play an important role in RA, but their number and significance have not been determined. RA tends to run in families. This study will examine the DNA (hereditary material) of patients with RA and their family members to try to determine which chromosomes(s) contain the genes responsible for the disease. Patients with rheumatoid arthritis and their family members may be eligible for this study. Participants with RA who have a brother or sister with RA will undergo the following procedures: Review of their medical records Medical history Examination of the joints Hand X-rays Blood tests Participants who 1) do not have RA but who have a relative with the disease, or 2) have RA and a relative other than a brother or sister who has the disease will provide a blood sample or a buccal (cheek) cell sample. Cheek cells are obtained by swishing a small amount of mouthwash in the mouth or by lightly bushing the inside of the cheek with a swab or brush. The samples will be tested for rheumatoid factor, DNA studies, and HLA type (a blood type found on white blood cells). Certain HLA types have been associated with an increased risk or severity of RA.
Fusion Rates and Cost Analysis of Patients Undergoing 1st Metatarsal Phalangeal Joint Arthrodesis...
First Metatarsophalangeal Joint ArthritisThis is a longitudinal, multi-center study to be conducted in at least five institutions from the private surgeon offices. These surgeons will collect data from X-rays, wound complications \and hardware complications.
Skin to Adductor Canal Distance in Various Positions
Knee ArthritisTo control pain after total knee replacement surgery a catheter (tubing) is sometimes inserted into an anatomic space containing nerves that provide sensation to parts of the knee. This space is called the adductor canal. The catheters often stop working before we remove them for unclear reasons. The investigators think this is because the catheters become dislodged from where it was meant to be. This could be due to repeated movements of the catheter tip brought on by patients contracting their leg muscles when they ambulate or perform physio. The investigators want to confirm this by measuring the distance from a fixed spot on the patient's thigh to the adductor canal using an ultrasound machine. The leg will be measured in various positions to simulate muscle movements. A significant change in the distance could possibly contribute to catheter dislodgement and result in catheter failure.
Neuromusuclar Adaptations in the Rheumatoid Arthritis Disease
ArthritisRheumatoid1 moreRheumatoid arthritis (RA) is a chronic autoimmune disease that causes joint inflammation and progressive joint destruction. Rheumatoid cachexia is one of the structural manifestations of RA, and consists of a reduction in muscle mass, due to an increased muscle protein catabolism induced by inflammatory cytokines. This muscle mass loss generates an impairment in physical function and functional capacity in RA patients. The aim of study was to verify neuromuscular and functional responses in middle-aged women with RA compared to paired healthy women.
Features and Outcomes of Patients With Reactive Arthritis
ArthritisThe aim of this study is to assess the incidence and the clinical and therapeutic characteristics of reactive arthritis and to compare them with those of a historical cohort. We hypothesised that improved hygiene together with prevention and treatment of sexually transmitted infections may have decreased the incidence of reactive arthritis.
Association Between Subtypes of Anti Citrullinated Peptide Antibodies and Lung Damage in Rheumatoid...
Rheumatoid ArthritisRheumatoid arthritis is a genuine systemic disease associated with diffuse interstitial pneumopathy and bronchial disorders. According to the literature review, the prevalence of PID on thoracic CT scan is one-third of patients. Diffuse interstitial pneumopathy is responsible for a significant morbidity and mortality, is currently under-diagnosed and its treatment is poorly codified. The lung seems to have a central role in the genesis of rheumatoid arthritis. It also appears that some subtypes of anti citrullinated peptide antibodies are preferentially present in the lungs. The hypothesis behind our project is that one or more subtypes of anti citrullinated peptide antibodies with a preferential tropism for the lung would attack the parenchyma and pulmonary airways. Currently, there are no data on interstitial pneumopathy in black and Afro-Caribbean subjects with rheumatoid arthritis.
Long- and Midterm Outcomes of Osteoarticular Infections in Paediatric Patients
Acute Haematogenous OsteomyelitisSeptic ArthritisMulti-centre clinical follow-up study on patients with a history of acute haematogenous osteomyelitis and/or septic arthritis. The aim is to describe the frequency of sequelae in these former patients with osteoarticular infections. Patients will be invited to participate in a single follow-up visit including a standardised interview and a clinical examination. The collected data will be analyzed together with data from the patient's hospital stay.
Subject Insights to Understand Rheumatoid Arthritis (RA)
ArthritisRheumatoidRheumatoid arthritis (RA) is a chronic, systemic autoimmune disease affecting the joints and can lead to joint pain, swelling, redness and stiffness and can cause deformity, loss of strength and immobility. This cross-sectional qualitative study aims to explore the burden of established RA by conducting semi-structured Concept elicitation (CE) interviews (60 minutes duration) and real-time data capture task. The conceptual model developed from this data will be used to support the development of GSK3196165, a recombinant human monoclonal antibody (mAb) targeted for the treatment of RA. The CE interviews will explore the subject experience of RA and will collect information about symptoms, disease impact on functioning and health related quality of life (HRQoL), and treatment experiences/impacts of the condition and the language used by subjects to describe them. Following the CE interview, subjects will be asked to complete a brief symptom ranking exercise where they will need to rank how bothersome each RA symptom is and how important it would be to improve with treatment on a 1-5 numerical rating scale (NRS). After the interviews, the real-time disease experience of subjects will be captured by the real-time data capture app-based activity over a period of 7 days. Approximately 30 English-speaking subjects from the United States (US) with RA who are inadequate responders of conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) and/or (bDMARDs) will participate in the interviews and of these, 10 subjects will be offered the opportunity to participate in the real-time data capture sub study.
