Assessment of Leflunomide Efficacy and Hepatotoxicity in Patients With Rheumatoid Arthritis Through...
Rheumatoid ArthritisThe RA patients receiving leflunomide for more than one month, and not receiving other DMARDs (except hydroxychloroquine), will be enrolled to assess their disease activity. Blood samples will be collected for genetic studies and pharmacokinetic assay of the blood levels of the drug and its active metabolite.

Monitoring the IMmUological TOXicity of Drugs
ArthritisSystemic Lupus Erythematosus3 moreSeveral drugs and chemotherapies seem to have an impact on the immunological system. This study investigates reports of immunological toxicities, including the International classification of disease ICD-10 codes M05, M32, I78 for treatments in the World Health Organization (WHO) global Individual Case Safety Report (ICSR) database (VigiBase).

Serum IL-17 Correlated With Inflammatory Changes in Osteoarthritis and Rheumatoid Arthritis
Rheumatoid Arthritis (RA) and Osteoarthritis (OA)The total number of the included subjects was 120 in 3 equal groups (RA, OA and control). All subject was subjected to serum IL17 level measurement. MSK US (of both wrists, MCPs, PIPs and DIPs) was done to all patients in RA and OA groups. Disease activity was measured by disease activity score (DAS28) for RA patients. Visual analogue scale for pain (VAS) was obtained from patients in RA and OA groups. Functional assessment was done using health assessment questionnaire (HAQ) for RA patients and the Australian/Canadian (AUSCAN) Osteoarthritis Hand Index for OA patients

Prospective Longitudinal Effects of Intra-articular Corticosteroid Injection on Synovial Fluid Oxygen...
Rheumatoid ArthritisPsoriatic ArthritisInflammatory arthritis such as rheumatoid arthritis (RA) and psoriatic arthritis (PsA) are characterized by synovial inflammation of joints, potentially leading to joint destruction and functional disability. Inflamed joints have lower oxygen levels. Studying how oxygen level within the joint affect inflammation may lead to new treatments for patients with arthritis. Anti-inflammatory corticosteroid injection into the joint is well tolerated and widely used in clinical practice but its effects on oxygen level within joints is unknown. Therefore, patients who require corticosteroid injection into the joint as routine clinical care will have biological samples collected before and after the injection. This will give new information to put into context the biological effects within the joint, and accelerate development of new treatment approaches in the future.

Assessment of Treatment Safety and Quality of Life in Patients Receiving Etanercept Biosimilar for...
Rheumatoid ArthritisAnkylosing Spondylitis1 moreIn this open-label, multi-center, observational, post-marketing surveillance study, patients with ankylosing spondylitis, psoriatic arthritis, or rheumatoid arthritis received biosimilar etanercept 25 mg twice weekly or 50 mg once weekly in real-world settings. Safety and effectiveness of biosimilar etanercept were evaluated in study participants for a duration of up to 12 months.

Patient Outcomes: Real World Evidence in Rheumatoid Arthritis (POWER)
Patient Outcomes: Real World Evidence in Rheumatoid Arthritis (POWER)This is a prospective, real-world observational study in which patients with RA who are initiating treatment with a JAK inhibitor medication will self-report disease activity and treatment satisfaction measures using their own web-enabled device such as a smartphone. Secondary objectives include analyzing the epidemiology and natural history of the disease, its comorbidities, and current treatment practices.

A Study on the Use of Tourniquet Use In Primary Total Knee Arthroplasty
Osteo Arthritis KneeRheumatoid Arthritis of KneeA tourniquet is often used in total knee arthroplasty (TKA) to achieve better visualization, reduce intra-operative bleeding and facilitate cement interdigitation. On the other hand, the associated risks include skin burns, soft tissue and muscle damage, injury of calcified vessels, increased swelling and stiffness of the joints, nerve injury, paralysis, and thromboembolic events. The automatic lower limb pneumatic tourniquet system (Zimmer) was applied to reduce blood loss during surgery. A prospective randomized controlled trial (RCT) was performed to investigate the best tourniquet strategy in TKA. The participants were randomly allocated to groups with different tourniquet strategies: Group 1) tourniquet inflation from skin to cement hardening (skin to cement); Group 2) tourniquet inflation only from cementation (cement only) and Group 3) tourniquet inflation from skin incision to skin closure (skin to skin). In addition to the blood loss and early postoperative outcomes, pain, soft tissue injury, and rehabilitation were also strictly monitored with a longer follow-up duration up to 6 months.

Effect of Tocilizumab to the Cellular Immune Response to Influenza Vaccine
Rheumatoid ArthritisCellular Immune ResponsePatients with rheumatoid arthritis (RA) are prone to respiratory infections and therefore recommmended to receive vaccination against seasonal influenza. We and others have shown a relatively preserved humoral response to vaccination in RA patients. However, the cellular response as well as the effect of biologics such as tocilizumab on the cellular response has not been weel studied. The purpose of this study is the evaluate the effect of tocilizumab on the cellular immune response to influenza vaccine in patients with RA in comparison with healthy controls
