Cohort profile: the clinical 'Psoriasis in Adolescents' (PIA) cohort in Denmark.

Purpose: Psoriasis is a chronic inflammatory skin disease that frequently debuts in childhood and adolescence. We wished to determine environmental and genetic risk factors for the development of psoriasis in children and adolescents, as well as to investigate debut type, trigger factors, course of disease, nature and influence of stress related to both child and family and risk factors for comorbidity. The 'Psoriasis in Adolescents' (PIA) cohort will provide data on the relationship between psoriasis and, respectively, genetic disposition, early-life exposures, quality of life and comorbidity.

Tonsillitis and pediatric psoriasis: Cohort and cross-sectional analyses of offspring from the Danish National Birth Cohort.

Background: Streptococcal tonsillitis has been implicated in psoriasis; however, few population studies have examined its role in the pediatric population.

Objective: To investigate the association between tonsillitis and pediatric psoriasis.

Methods: Data from the Danish National Birth Cohort were obtained on parentally reported psoriasis by age 11 years and history of tonsillitis at ages 6 to 18 months, 10 to 11 years, and (from hospital patient registry data) 0 to 11 years.

Ixekizumab for the treatment of psoriasis: an update on new data since first approval.

: Psoriasis is a chronic immune-mediated skin disease with a multifactorial etiology. Studies have shown that the inflammatory cytokine interleukin-17A (IL-17A) is a key mediator in the pathogenesis. Targeted biologics have changed the outcome for patients in a variety of diseases including psoriasis.

Psoriasis as a Predictor of Cardiometabolic Comorbidity in Women: A Study Based on the Danish National Birth Cohort.

Psoriasis is associated with cardiometabolic comorbidity; however, whether this is due to common lifestyle-related risk factors is unclear. This study investigated the association between psoriasis and cardiometabolic comorbidity, taking body mass index and smoking into account. The population comprised expectant mothers in the Danish National Birth Cohort (established 1996-2002).

Autoimmune Disease in Children and Adolescents with Psoriasis: A Cross-sectional Study in Denmark.

Psoriasis is an immune-mediated inflammatory disease, which, in studies among adults, have been shown to cluster with autoimmune disease. The aim of this cross-sectional register study was to examine possible associations between 9 pre-selected autoimmune diseases and psoriasis in children and adolescents. The study population consisted of all individuals living in Denmark, age under 18 years on 31 December 2012.
