OBJECTIVES To compare the association between known risk alleles and psoriasis in well-defined cohorts with paediatric- and adult-onset psoriasis. METHODS Based on previous studies we(More)
This study aims to investigate associations between observed clinical parameters and known genetic risk factors of psoriasis in a well-defined prospective cohort of paediatric patients with plaque psoriasis (n = 151). Significant associations were found for paediatric-onset psoriasis with ERAP1 (p = 0.002), IL23R (p = 0.01), LCE3C_LCE3B-del (p = 0.00049)(More)

OBJECTIVE This study aims to evaluate the effectiveness and safety of calcipotriene/betamethasone dipropionate scalp formulation for paediatric scalp psoriasis in daily clinical practice. The influence of this formulation on the quality of life(More)
BACKGROUND Evidence on effectiveness and safety of methotrexate (MTX) in pediatric psoriasis is scarce. OBJECTIVES To study the effectiveness and safety of MTX in pediatric plaque-type psoriasis and its influence on quality of life (Qol) in daily clinical practice. METHODS Subset analysis of prospectively collected data extracted from the Child-CAPTURE(More)
BACKGROUND Psoriasis in children has a significant negative impact on the quality of life (QoL) and effective treatment can improve this. The two-compound ointment calcipotriol 50 μg g(-1) and betamethasone dipropionate 0·5 mg g(-1) is an effective treatment option for moderate-to-severe psoriasis in adults. OBJECTIVES To study prospectively the(More)
This aim of this study was to validate the Scalpdex, a quality of life questionnaire for adults with scalp dermatitis, in children with scalp psoriasis. The reliability, responsiveness and validity of the 3 scales (symptoms, functioning and emotions) of this 22-item questionnaire were analysed in a cohort of children with scalp psoriasis (age range 6-18(More)
BACKGROUND Fumaric acid esters (FAE) are used as an effective and safe oral treatment for plaque psoriasis in adult patients, but little is known about their efficacy and safety in children with psoriasis. OBJECTIVES To assess the effectiveness and safety of FAE in the treatment of paediatric psoriasis. METHODS This is a retrospective analysis of 14(More)
BACKGROUND Evidence on fumaric acid esters (FAE) in the treatment of pediatric psoriasis is scarce. OBJECTIVE Describe the effectiveness, influence on the quality of life (QoL) and safety of FAE in children with recalcitrant psoriasis in daily clinical practice. METHODS A prospective case series. RESULTS Fourteen patients with recalcitrant plaque-type(More)
INTRODUCTION To describe and illustrate in a case-study design the development and design of a multidisciplinary training program for outpatient children and adolescents with psoriasis and their parents.
