Features of sleep disorders in children with psoriasis and comorbid pathologies

Purpose of the study . To analyze observations of sleep disorders in children with psoriasis and comorbid diseases. Materials and methods . This article describes clinical cases of sleep disorders in 14- and 15-year-old patients with psoriasis and comorbid diseases (psoriatic arthritis (PsA) and exogenous-constitutional obesity of the 2nd degree) who were treated at National Medical Research Center for Children’s Health of the Ministry of Health of the Russia. Results . Based on the results of collecting anamnesis and polysomnographic study (PSG), it was found that a 14-year-old child with a combination of severe plaque psoriasis (PASI index-21.3 points) and PsA had restless legs syndrome (RLS) of moderate severity, decreased sleep efficiency, and increased sleep fragmentation due to frequent awakenings. A 15-year-old patient with severe plaque psoriasis (PASI-66 score) and grade 2 exogenous-constitutional obesity had moderate obstructive sleep apnea syndrome (OSAS), as well as increased time to fall asleep, reduced sleep efficiency, and increased sleep fragmentation due to frequent awakenings. Conclusions . Sleep disorders are common in children with psoriasis and comorbid pathologies. At the same time, the implementation of a specific variant of dyssomnia or parasomnia depends on both the underlying disease and the concomitant ones.
