Biobank for Inflammatory Chronic Diseases and Osteoporosis
The aim of this study is to constitute a biobank for patients followed in the Rheumatology center of Toulouse University Hospital for a chronic inflammatory rheumatism including rheumatoid arthritis (RA), spondyloarthritis(SpA), and psoriatic arthritis (PsA) or a chronic bone disease including osteoporosis in order to identify biomarkers associated with therapeutic response.

BIOTIPRA: BIOmarker-guided Treatment Decisions In Psoriatic and Rheumatoid Arthritis
TNFi drugs remain the most prescribed first-line biologics for patients with rheumatoid arthritis (RA). However, up to 40% of RA patients fail to respond to TNFi treatment. One explanation of non-response is the development of anti-drug antibodies and low drug levels. Studies have consistently shown that: 1. Serum drug levels of monoclonal antibodies (such as adalimumab, certolizumab, infliximab) and the presence of anti-drug antibodies in samples taken at 3 and 6 months correlate with subsequent response at 12 months. 2. Non-responders and those who develop anti-drug antibodies are less likely to receive ...

Brain Changes in Psoriasis After Secukinumab Treatment
The purpose of this study is to assess the effect of a biologic drug targeting the Interleukin (IL)-17 pathway (secukinumab) on brain plasticity and examine whether the plastic changes correlate with the improvement of perception of well-being, itch, and pain in participants with psoriasis.

Canadian Real World Evidence Study of Brodalumab in Plaque Psoriasis to Understand the Impact on Quality of Life and Work Productivity
This is a phase IV, 12-month observational, prospective, open-label, multi-center study that will be conducted across approximately 50 sites in Canada for an estimated study duration of 32 months. All eligible adult participants who are enrolling into the SILIQ Patient Support Program (PSP) and initiating brodalumab as per routine care may be offered participation in the study. If the participant agrees, their verbal consent and details will be entered into the study platform by the enrolling physician so that the participant can access the electronic informed consent form. Participants who meet the eligibility criteria and provide ...

Cardiovascular Risk Predictors in Patients With Psoriasis
The investigators are planning to find the right modification of traditionally used risk scores (PASI, DLQI) in patients with psoriasis of different severity to guide the treatment that could potentially extend life, improve cardiovascular outcomes and quality of life in patients with psoriasis and cardiovascular risk factors in a prospective observational study. The traditionally excluded groups of older patients with diabetes mellitus, decreased kidney function and those with potentially worse prognosis are going to be included in the study. As it's known, the number of those patients is on the rise each year and require a close ...

Changes in Body Composition Under Ustekinumab in PsA
There is not much body composition and bone mineral density data available for patients with psoriatic arthritis (rheumatoid arthritis) compared to control subjects. The evaluation of the total fat mass and in particular of its abdominal distribution (visceral adiposity) is important because an excessive adiposity generates adverse effects on the health (hypertension, dyslipidemia, cardiovascular risk and resistance to the insulin). In addition, data on changes in body composition and bone mineral density were not available under a new psA treatment, namely ustekinumab (anti-IL12 / 23 antibody). It is proposed to conduct a...

Characterization of Immunogenicity of TNF Inhibitors in Arthritis Patients With Poorer Treatment Response.
The aim of the study is to explore whether the influence of gender, tobacco smoking and obesity on treatment response in tumor necrosis factor inhibitors (TNFIs) can be explained by high degree of inflammation, human leucocyte antigen (HLA) type, autoantibodies, TNF and TNFI concentration and presence of ADA.

Characterization of Lipoprotein Composition and Function in Pediatric Psoriasis Before and After Treatment
This study will assess differences in inflammatory proteins, lipoprotein composition, cholesterol efflux and HDL-proteome in moderate-to-severe pediatric psoriasis who at baseline begin systemically administered therapy vs: a) healthy controls; and b) patients with milder psoriasis.
