Active clinical trials for "Spondylitis, Ankylosing"

The aim of this study was to determine the status of ovarian reserve in patients with ankylosing spondylitis (AS) using anti-mullerian hormone (AMH) level and antral follicle count (AFC). Women with AS and women controls diagnosed according to the classification criteria proposed by the American-European Consensus Group will be included in the study. Ovarian reserve will be evaluated in terms of clinical findings, AFC and serum AMH and reproductive hormone levels. Researchers predict that the ovarian reserve may be reduced in patients with AS due to the autoimmune process and the pathophysiology of the disease. Serum AMH and ovarian AFC may be useful for assessing ovarian reserve. It is aimed to determine the course of ovarian reserve abnormalities and the best possible biomarkers of reduced ovarian reserve in patients with AS.

In 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.

The purpose of this study was to assess the proportion of AS patients achieving treatment response to adalimumab therapy.

Rheumatoid arthritis (RA) and ankylosing spondylitis (AS) are characterized by chronic systemic inflammation and share common pathogenic pathways. In both diseases, cytokines like TNF (tumor necrosis factor) and interleukin (IL)-17, known for their pro-inflammatory and osteoclastogenic effects, are relevant players, however, while RA is characterized by bone erosions, AS favors bone overgrowth. Understanding this paradox may hold the key for a better management of both diseases. Our hypothesis is that there are differences in the cellular environment and intracellular signaling between AS and RA. To test this hypothesis we will evaluate the cytokine milieu, the kinetics of bone cells differentiation and their activity in untreated and immunosuppressed RA and AS patients. We will also perform the same observations in patients exposed to targeted treatments.

This 12-month postmarketing observational study (PMOS) was a prospective, single-arm, multicenter, multi-country study, with follow-up visits at 3, 6, 9, and 12 months after the initial baseline visit. The study was conducted to determine the long-term effectiveness of treatment with adalimumab in routine clinical use in participants with Ankylosing Spondylitis (AS) and Psoriatic Arthritis (PsA) in Central and Eastern European Countries.

The research question explored in this study was whether the effectiveness and safety of adalimumab in participants with ankylosing spondylitis was maintained during long-term therapy in routine clinical practice in Germany.

This is a non-interventional, post-marketing, observational study (PMOS) in which Humira (adalimumab) is prescribed in the usual manner in accordance with the terms of the local marketing authorization with regards to dose, population and indication. No data currently exists to characterize patient populations being prescribed Humira in Eastern Europe. Further, it is important to establish the clinical outcome and tolerability of Humira in Eastern European patients, as well as their compliance with Humira treatment, in particular the acceptability of self-injection, which may influence all of the above in routine clinical practice.

This is a five year, post-marketing observational study to follow-up patients with rheumatoid arthritis, psoriatic arthritis or ankylosing spondylitis who are treated with HUMIRA (adalimumab).

This prospective study will assess the effects of treatment with alendronate in osteoporotic patients with ankylosing spondylitis. Primary objectives: To investigate if alendronate effect bone mineral density (BMD) assessed by dual energy x-ray absorptiometry (DXA) in lumbar spine, hip and distal forearm and assessed by quantitative computed tomography (QCT) in lumbar spine and by Xtreme CT in radius and tibia. Secondary objectives: To investigate if alendronate effects markers of bone remodeling To investigate if alendronate influences disease activity (BASDAI), spinal function (BASFI), spinal movement (BASMI) and health related quality of life (SF-36).

This study aims to provide a holistic assessment of patients receiving etanercept in a real-world setting.
