Real-world Methotrexate Use in a Prospective Cohort of Paediatric Patients with Plaque Psoriasis: Effectiveness, Adverse Events and Folic Acid Regimen.

In paediatric psoriasis, few studies have evaluated methotrexate effectiveness, adverse events and folic acid regimen. Therefore this study prospectively assessed methotrexate adverse events and effectiveness in paediatric patients with psoriasis in a real-world setting. Furthermore, gastrointestinal adverse events and methotrexate effectiveness were compared between folic acid regimens (5 mg once weekly vs 1 mg 6 times weekly).

[Terbinafine resistance explains treatment failure in a patient with tinea corporis].

Background: Tinea corporis is a superficial fungal infection of the limbs, chest or back caused by dermatophytes. Local antifungal treatment is often sufficient to treat tinea corporis. Systemic treatment may be needed in more severe cases, in immunocompromised patients or when treatment failure is documented.

A Comparison of Psoriasis Severity in Pediatric Patients Treated With Methotrexate vs Biologic Agents.

Importance: Few studies have compared the use of methotrexate and biologics, the most commonly used systemic medications for treatment of moderate to severe psoriasis in children.

Objective: To assess the real-world, 6-month reduction in psoriasis severity and long-term drug survival (rate and duration of adherence to a specific drug) of methotrexate vs biologics in plaque psoriasis in children.

Design, Setting, And Participants: A retrospective medical records review was conducted at 20 European and North American centers.

Association Between Quality of Life and Improvement in Psoriasis Severity and Extent in Pediatric Patients.

Importance: Treatment of psoriasis is associated with improved quality of life (QOL) in those with the disease. However, in daily clinical practice, the association between the degree of psoriasis clearance and QOL has not been studied to date, especially in the pediatric population.

Objectives: To identify the association between the degree of psoriasis improvement (as measured by the Psoriasis Area Severity Index [PASI] and body surface area [BSA] response) and QOL (as measured by the Children's Dermatology Life Quality Index [CDLQI]) in pediatric psoriasis, and to assess the association of treatment type with QOL, independent of psoriasis improvement.

Nail Involvement as a Predictor of Disease Severity in Paediatric Psoriasis: Follow-up Data from the Dutch ChildCAPTURE Registry.

Little is known about the relationship between nail psoriasis and psoriasis severity in children, and there has been no longitudinal assessment of psoriasis severity related to nail psoriasis. The aim of this study was to assess whether nail psoriasis could serve as a predictor for a more severe disease course. De-identified data were obtained from the ChildCAPTURE registry, a daily clinical practice cohort of children with psoriasis, from September 2008 to November 2015.

A cross-sectional study in young adults with psoriasis: potential determining factors in quality of life, life course and work productivity.

Background: Psoriasis can have a substantial impact on health-related quality of life (HRQoL), life course, and work productivity. Young adulthood is a critical, sensitive period of development that includes major life changing decisions. The impact of psoriasis on this vulnerable population is yet unknown.

Safety of Systemic Agents for the Treatment of Pediatric Psoriasis.

Importance: Use of systemic therapies for moderate to severe psoriasis in children is increasing, but comparative data on their use and toxicities are limited.

Objective: To assess patterns of use and relative risks of systemic agents for moderate to severe psoriasis in children.

Design, Setting, And Participants: A retrospective review was conducted at 20 centers in North America and Europe, and included all consecutive children with moderate to severe psoriasis who used systemic medications or phototherapy for at least 3 months from December 1, 1990, to September 16, 2014.
