Active clinical trials for "Arthritis"

Trapezometacarpal protheses are implanted for patients with trapezometacarpal arthritis. Having a pre-operative thumb adduction angle of less than 25 degrees with hyperextension, meaning a " Z-deformity " are somehow a reason to go for another surgical treatment: trapezectomy with ligament reconstruction. This study will aim at analyzing the results of another surgical treatment which is the trapezometacarpal arthroplasty in this type of deformities.

Erosive osteoarthritis of the hand (EHOA) is a rare subset of HOA that affects mainly postmenopausal middle-aged women, featured by prominent signs of inflammation, severe progression, and typical radiographic changes of the interphalangeal (IP). It is presently debated whether EHOA is an advanced stage of the classical HOA or a separate entity with peculiar inflammatory features, which can mimic chronic arthritis such as psoriatic arthritis (PsA). PsA is a chronic immune-mediated inflammatory arthropathy, that affects 14.0-22.7% of patients with psoriasis. It is a highly heterogeneous disease, whose clinical features often vary from peripheral arthritis, to spinal spondylitis, and/or asymmetrical synovitis, enthesitis, dactylitis. As no gold-standard diagnostic test for PsA exists, the diagnosis is based on different patterns of clinical, radiological and serological markers included in the classification criteria for psoriatic arthritis (CASPAR). Some typical features of PsA are also observed in other chronic musculoskeletal diseases, as rheumatoid arthritis (RA) and HOA, determining possible delay of the diagnosis and consequent influence on the successful results of the therapies. In particular, the differential diagnosis of PsA and EHOA is very challenging, considering that both conditions can be characterized by bone proliferation and inflammation processes in the distal IP joints and lack of specific diagnostic biomarkers. In the last decade, microRNA (miRNA) are emerged as possible candidate biomarkers in different rheumatic diseases. They are a class of small non-coding RNA molecules implicated in the direct regulation of the expression of different target genes by repressing or inhibiting translation. Mature miRNA are produced inside the cell and exert their function in the cytoplasm, but also by being released into the circulation and body fluids, where they regulate both physiological and pathological processes. Specific profiles of miRNA have been associated with the up-regulation of several inflammatory cytokines or degrading enzymes involved in the pathogenesis of PsA or OA. Indeed, miRNA have been detected in human plasma and in synovial fluid from patients with PsA and are considered possible diagnostic and prognostic biomarkers of this disease; very recently a pattern of circulating miRNAs has been studied also in patients with HOA. IThe aim of the present study is to test whether miRNA can help to differentiate EHOA from PsA. In detail, the investigators evaluate the expression profile of a series of miRNA (miR-21, miR-140, miR-146a, miR-155, miR-181a, miR-223, miR-23a, miR-26a and miR-let-7e), known to be dysregulated in PsA and OA, in peripheral blood mononuclear cells (PBMCs) of patients with EHOA and PsA and in comparison to a group of healthy controls (HC). Furthermore, the investigators assess the potential correlation between miRNA expression and disease activity.

This study is a retrospective multicenter study to review the use of Simplex High Viscosity Bone Cement in Primary Total Knee Arthroplasty

The wrist is often considered to be the fundament of the hand. Patients with a destroyed wrist joint caused by osteoarthritis or rheumatoid arthritis may suffer from pain and functional disabilities with impaired life quality. The traditional surgical solution for advanced wrist arthritis is a total wrist fusion (TWF). Although TWF creates a stable wrist with minimal pain, the prize is the joint motion. Total wrist arthroplasty (TWA) is a motion-preserving alternative, but has failed to achieve the widespread use of other joint replacement procedures. TWA is more costly and technically demanding than TWF, and also associated with more complications. In addition, there is no consensus regarding the functional benefit of a TWA compared to TWF since prospective, comparative studies are missing. Aim: The purpose of this prospective cohort study was to compare functional outcome and activity limitations up to two years after surgery with TWA or TWF.

The purpose of this clinical trial is to prospectively evaluate RA activity using the assessment of change in DAS28 under local conditions in Slovakia in participants who are treated with subcutaneously administered tocilizumab pursuant to the recommendations of the Ministry of Health of the Slovak Republic in order to better assess the disease activity and impairment of the joint function.

This study will establish a comparison in follow-up care of 100 patients between Health Care Practitioners, more specifically the rheumatologist and a trained nurse. The study objective is to show consistency of evaluation between two different health care professionals, a physician and a nurse.

Rheumatoid Arthritis (RA) is a chronic and potentially severe autoimmune disease affecting 2 million in the United States. The role of environmental factors in modulating autoimmunity pathogenesis has been clearly described and yet the specific mechanisms of action remain poorly understood. A growing body of evidence implicates microbiota of mucosal surfaces in the development of autoimmune disorders. Various studies have clearly linked RA to periodontal disease. The latter is linked to the red-complex that includes the oral bacterium Porphyromonas gingivalis. And yet there has not been a systematic analysis of the oral microbiota in RA to determine whether there are specific markers for P. gingivalis (and other oral bacteria) that are linked to RA. In this study, the investigators will characterize oral microbial composition (microbiome) and gene content (metagenome) of DNA isolated from oral samples obtained from patients with (i) early stage RA prior to biologics treatments and (ii) subsets of RA patients who are responsive or unresponsive to anti-TNF-alpha therapy. The innovative aspect of this study is going beyond the identification of oral bacterial species, to the level of strains and genes that are associated with these groups. The overall hypothesis is that oral microbial variation exists between individuals that influences development of autoimmunity and autoimmune disease.

The purpose of this study is to increase our understanding of infertility in women with Rheumatoid Arthritis (RA). In this study the study team will compare the differences in ovarian reserve (the ability to provide egg cells that are capable of fertilization), the frequency of ovulation and the number of pregnancies between women with and without RA. It is possible that RA activity and medications limit ovarian reserve and ovulation, which may increase infertility among women with RA. There are several suspected causes for infertility in RA, including age-related fertility decline, inflammatory changes that impact endometrial receptivity and discourage implantation, accelerated ovarian decline due to certain arthritis medications and increased frequency of anovulation (a menstrual cycle during which ovaries do not release an egg) due to RA activity. This study is the first step toward our long term goal of increasing the ability of all women with RA to build the family they desire.

The purpose of this study is to conduct full psychometric testing of the Early Arthritis for Psoriatic Patients (EARP) questionnaire in Australian, Korean and Chinese populations

This multicenter, prospective, non-interventional study is designed to obtain an accurate estimation of the drug retention rate of Tocilizumab (TCZ) Subcutaneously (SC) under real-world conditions in participants with moderate to severe rheumatoid arthritis (RA).
