Active clinical trials for "Psoriasis"

The purpose of this study is to understand how genetics play a role in psoriasis. Specifically, a genetic allele HLA-Cw6 is known to be associated with psoriasis, and this study aims to find out how it affects genetic and protein expression in patients with psoriasis, compared to healthy people, at a single-cell level using a novel flow cytometry and RNA-sequencing protocol.

The objective of this non-interventional, observational study is to assess the effectiveness and patient reported outcome of adalimumab in patients with moderate to severe psoriasis in real world clinical practice in China.

Atopic dermatitis (AD) and psoriasis (PS) are chronic, relapsing dermatological disorders with a high rate of psychiatric co-morbid pathology represented with depression. Brain Derived Neurotrophic Factor (BDNF) belongs to the neurotrophin family and widely studied in pathophysiology of psychiatric and dermatological disorders. A biological stress response system by altered hypothalamic-pituitary-adrenal (HPA) axis as well hypothalamic-pituitary-gonadal (HPG) axis may contribute to dermatoses and psychiatric disorders development. Various factors including gender, genetic, psychological stress, socioeconomic factors also affect the course of dermatoses. A 10-week, case-control study evaluate clinical, psychological and biochemical parameters in AD and PS patients, and healthy control volunteers (HC) depending on gender and BDNF rs6265 gene polymorphism. All parameters are evaluated twice: at disease exacerbation (study baseline) and week 10. The following methods are conducted: assessment of dermatological status, using Scoring of Atopic Dermatitis (SCORAD) and Psoriasis Area and Severity Index (PASI); assessment of depression and anxiety according to DSM-V criteria and with Hamilton Depression Rating Scale (HAM-D) and with Hamilton Anxiety Rating Scale (HAM-A); analysis of serum BDNF (ng/ml), cortisol (nmol/L), testosterone (ng/dL) and IgE levels (IU/ml, AD only); DNA extraction and genotyping of BDNF variants.The study will last during 4-5 months.

The primary aim of the study is to assess the effect of methotrexate on the development of distal interphalangeal joint extensor tendon enthesopathy.

This study is to evaluate available local data in Iraqi patients with moderate to severe psoriasis on Enbrel treatment with regards to efficacy, treatment regimen adherence and patient characterization (i.e. age, gender, smoking status) using data from the Dermatologists in Baghdad Teaching Hospital registry

COVID-19 had a major impact on dermatology practice globally with special emphasis on chronic diseases e.g. psoriasis. The main objective of this work is to investigate the effect of COVID-19 pandemic on psoriasis management. This work is designed as a cross-sectional survey based on a questionnaire directed to Egyptian dermatologists.

The aim of this study is to understand which therapies will suppress effector cells and promote regulatory T cells and To test whether patients with a better response to therapy and longer psoriasis-free periods develop a higher numerical ratio of regulatory to effectors T-cells and/or regulatory cells more able to suppress the effectors.

There is clearly a need for further data on the efficacy of biologic agents in the treatment of nail and scalp psoriasis, especially in the routine clinical setting. A few case reports can be found, but no published data exists from non-interventional studies, such as post-marketing observational studies (PMOS) that reflect routine clinical practice. The aim of this PMOS is to evaluate the long-term (12-month) efficacy of adalimumab in the treatment of nail and scalp psoriatic lesions in routine dermatologic practice.

Psoriasis is a chronic, often severe, autoimmune condition that affects approximately 2% of the world's population. The epidemiology of pediatric psoriasis has not been well documented and no treatment guidelines exist for pediatric psoriasis. Etanercept is a biologic drug and has been licensed for the treatment of chronic severe plaque psoriasis in children and adolescents (6-17 years of age) who are inadequately controlled by or are intolerant to, other systemic therapies or phototherapies. Although the long-term safety and efficacy of etanercept in children with juvenile idiopathic arthritis (JIA) has been studied and the short-term safety profile of etanercept in both JIA and pediatric psoriasis appears similar, there is limited data available about the long-term effects of etanercept in pediatric psoriasis, especially with respect to malignancy. The aim of this study is to assess the safety and effectiveness of etanercept for the treatment of pediatric psoriasis in Europe. Patients aged <=17 with plaque psoriasis diagnosed by a dermatologist will be invited to participate in the registry only after a clinical decision has been made to prescribe etanercept. The safety of the drug and how well the drug works will be evaluated during the follow-up period. The follow-up period will last 5 years and patients will be followed up every 3 months for the first 2 years and every 6 months for the next 3 years or until the end of study.

Psoriatic Arthritis (PsA) is a comorbidity that affects a significant proportion of participants with moderate or severe psoriasis. The purpose of this study was to describe the profile of patients with moderate or severe plaque psoriasis (Ps) in Colombia and to evaluate adalimumab efficacy and safety profile.
