Psoriasis and metabolic and cardiovascular comorbidities in children: A systematic review

Abstract Introduction Psoriasis is associated with a higher risk of cardiovascular and/or metabolic comorbidity in adults, but discordant data have been reported in children. Objective To evaluate the frequency of metabolic and cardiovascular comorbidity in children with psoriasis and to establish whether age at onset of psoriasis correlates with metabolic and cardiovascular comorbidity in adulthood. Material and methods We conducted a systematic review on MEDLINE, using PubMed and Ovid. The search was limited to children ( Results A total of 377 potential citations were analyzed. After removing duplicate articles and reviewing eligibility in titles and abstracts, 16 articles remained. The studies analyzed revealed significantly higher risk of overweight and obesity in children with psoriasis, despite the numerous definitions used. Four studies reported higher risk of abdominal obesity in children with psoriasis. Data on hypertension, diabetes, dyslipidemia, metabolic syndrome, and major cardiovascular events suggested there was no higher risk of these comorbidities in children with psoriasis. Two studies suggested that age at onset of psoriasis did not increase the frequency of comorbidity in adulthood. Conclusion This systematic review suggests that psoriasis in children is not associated with metabolic and cardiovascular comorbidities, except overweight and obesity, for which higher prevalence is clearly demonstrated in the literature.
