Quality of Life of Infants, Toddlers and Preschoolers with Seborrhoeic, Allergic Contact and Atopic Dermatitis Before and During COVID-19 Pandemic

INTRODUCTION: Different aspects of quality of life (QoL) of infants and children with atopic dermatitis (AD) are well studied but there is a lack of studies on seborrhoeic dermatitis (SD) and allergic contact dermatitis (ACD). The aim of this study was to compare the impact of SD, ACD and AD on young children. Parts of questionnaires were filled in during the COVID-19 pandemic and therefore we decided to check if the pandemic affected dermatology-specific health-related quality of life (HRQoL) in our patients. METHODS: In this cross-sectional study approved by the local ethics committee of the Kiev City Clinical Dermatovenereologic Hospital parents of children with SD, ACD and AD from birth to 4 years old from the same department of dermatology were asked to fill in the dermatology-specific questionnaire the Infants and Toddlers Dermatology Quality of Life (InToDermQoL). Diagnoses were based on clinical manifestations and anamnesis. The study was carried out from 2018 till 2021. RESULTS: The InToDermQoL questionnaire was filled in by 176 parents of children with SD, ACD and AD. Mean total InToDermQoL scores were significantly higher in children with AD than in SD and ACD (P < 0.01). HRQoL of children with AD during the COVID-19 pandemic was significantly worse than before pandemic (41.30 ± 24.40 and 28.51 ± 17.67 respectively, P = 0.02). Scores of the item on ‘sleep problems’ significantly decreased during the COVID-19 pandemic in children with SD (1.19 ± 1.01 and 0.64 ± 0.63, P < 0.05), as did scores of the item on ‘rejection by other children’ in children with AD (0.96 ± 0.98 and 0.20 ± 0.45, P < 0.05). CONCLUSIONS: To the best of our knowledge this is the first study on HRQoL of the youngest children with SD and ACD. In our study children with SD and ACD had comparable but lower impact of skin disease on their HRQoL than children with AD. The COVID-19 pandemic led to more severe HRQoL impairment in patients with AD visiting a dermatology department.
