JAK-STAT Signaling Pathway in Pyoderma Gangrenosum
The investigators hypothese that Janus kinase/signal transduction and activator of transcription (JAK/STAT) signaling pathway play a key role in pathophysiology of pyoderma gangrenosum (PG). In this study JAK/STAT signaling pathway will be investigated in the skin biopsies of PG patients

Laser Induced Changes to Innervation and Vascularisation of Psoriatic Skin
The researchers investigate the effect of a treatment with selective photothermolysis using a 595 nm pulsed dye laser on the blood vessel density and the nerve fibre density of a psoriatic lesion. By comparing tissue samples collected before and after two treatments, the researchers determine the relative effect of laser therapy on the (hyper)innervation of psoriatic skin.

Liver Fibrosis and Gut Microbiota in Patients With Psoriasis Vulgaris and Rheumatoid Arthritis on Methotrexate
While methotrexate (MTX) remains a treatment of choice for patients with rheumatoid arthritis (RA), psoriasis (PsO) and psoriatic arthritis (PsA), long-term MTX use has been shown to be associated with liver fibrosis and cirrhosis in these patients. In addition, gut dysbiosis has been found to be associated with liver fibrosis and cirrhosis via the gut-liver axis, underscoring the potential role of gut microbiota and bacterial translocation in the pathogenesis of chronic liver diseases in these patients. In this study, we aim to assess the prevalence of advanced liver fibrosis or cirrhosis among these patients on MTX treatment...

Methotrexate Versus Secukinumab Safety in Psoriasis Patients With Metabolic Syndrome
A prospective, controlled, open trial in psoriasis patients with metabolic syndrome, candidate to methotrexate or secukinumab was conducted between January 2019 and May 2020. The primary end point of the study was investigating any variations in waist circumference, body mass index (BMI), blood pressure, fasting glucose, total cholesterol, low density lipoprotein (LDL)-cholesterol, high density lipoprotein (HDL)-cholesterol, triglycerides, aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine levels between baseline and month-6 and 12 of follow-up.

Outcomes With Treatment and Withdraw of Secukinumab in Patients With Plaque Psoriasis
Psoriasis (PsO) is a systemic immune disease that affect 2-4% of the population worldwide. PsO causes tremendous burden in terms of quality of life, psychological impact, disability and work productivity of affected individuals. PsO is associated with an increased risk of cardiovascular morbidities and mortality in the long term. Up to 30% of PsO patients develop psoriatic arthritis (PsA) over time causing joint deformities and further disabilities. Majority of patients with PsA developed PsO first, and arthritis develop 5-10 years after. PsA and PsO are increasingly recognized as two entities under the umbrella of psoriatic ...

Quantitative Ultrasound of the Enthesis in Fibromyalgia and Psoriatic Arthritis
This prospective, cross-sectional, observational study will include subjects with fibromyalgia (FM), psoriatic arthritis (PsA) and asymptomatic controls. Participants will undergo a research ultrasound (US) exam of the enthesis of the Achilles' tendon, the medial collateral ligament at the femoral epicondyle and the common extensor tendon at lateral epicondyle of the elbow in resting conditions. The research US exam will consist of shear wave elastography (SWE) and radiofrequency (RF) data acquisitions. SWE technology will allow quantification of the shear wave speed (SWS) reporting the elastic stiffness of the tissues under...

Role of Brodalumab in the Modulation of Gut Microbiome in Psoriatic Patients
BOMOGUMIP is an interventional research with minimal risk and constraints (cat.2), exploratory, intra-individual, prospective, multi-site study. The main objective of this intra individual prospective study is to determine the evolution of microbial composition of fecal samples issued to 15 patients after 6 months of Brodalumab treatment. The population will consist of 15 adult patients suffering from moderate to severe skin psoriasis and starting, after having received a methotrexate treatment during at least 4 months, a brodalumab treatment in the first line of biological treatment.
