Pruritus in pediatric patients with atopic dermatitis: a multidisciplinary approach - summary document from an Italian expert group.

ABSTRACT: Given the inadequate overall awareness of the main disease features and treatment modalities of pruritus in pediatric patients with atopic dermatitis, a multidisciplinary Italian expert group met with the major aim of increasing knowledge of the condition for improved diagnosis and better management among specialists involved in disease management. Herein, the overall features of the condition are reviewed, along with its etiopathogenesis and symptoms. Likewise, management options are summarized, emphasizing the need for a multidisciplinary approach, minimally composed of a management team that includes a pediatrician, dermatologist, psychologist, play assistant, and dedicated nurse. In addition to more traditional therapies such as emollients as highlighted by European guidelines, therapeutic patient education in a group or individually is highly encouraged as it helps patients and their parents to better understand the disease and provide practical guidance for dressing and bandaging. It can also aid in outlining coping strategies for itching and sleep disturbance. The utility of distraction techniques should also be stressed as such educational interventions involving the child and their parents can substantially improve the overall quality of life. All approaches should be tailored according to patient age and clinical features and requires individualized strategy to ensure good adherence by both children and their parents. Thus, a holistic approach embracing systemic, topical and psychological interventions is advocated in order to provide patients and their caregivers the best possible care.

Project description:ImportanceThere is a paucity of data addressing the risk of cataract development in pediatric patients with atopic dermatitis (AD).ObjectiveTo investigate the association of AD with subsequent cataract development and cataract surgery in a Korean pediatric population.Design, setting, and participantsThis population-based retrospective longitudinal cohort study used nationally representative data from the Korean National Health Insurance Service database from 2002 to 2013. Incident AD cases, consisting of patients younger than 20 years with AD and severe AD and were matched to 4 controls each using propensity score derived from age, sex, residential area, and household income.Main outcomes and measuresIncidence probabilities of cataract development and cataract surgery between the AD group and controls were compared using Kaplan-Meier methods and log-rank tests. Cox proportional hazard models were fitted for cataract and cataract surgery to determine the risk factors in the matched cohort.ResultsOf 34 375 patients with incident AD (16 159 girls [47%]; mean [SD] age, 3.47 [4.96] years), there were 3734 severe AD cases (10.9%) with 137 500 matched controls. Development of cataracts was not different between the AD and control groups, (0.216% vs 0.227%; 95% CI, -0.041% to 0.063%; P = .32) or between the severe AD cohort and their controls (0.520% vs 0.276%; 95% CI, -0.073% to 0.561%; P = .06). Cataract surgery was performed more frequently in the AD cohort than in the control group (0.075% vs 0.041%; 95% CI, 0.017%-0.050%; P = .02) and in the severe AD cohort compared with their controls (0.221% vs 0.070%; 95% CI, 0.021%-0.279%; P = .03). Severe AD was associated with both development of cataract (adjusted hazard ratio, 1.94; 95% CI, 1.06-3.58, P = .03) and requirement for cataract surgery (adjusted hazard ratio, 5.48; 95% CI, 1.90-15.79, P = .002).Conclusions and relevanceAbsolute risk of cataract was rare, with or without AD, even after 10 years of observation. However, our results suggest that pediatric patients with AD have an increased risk for cataracts requiring surgery and that disease severity may increase the risk for cataract development and cataract surgery.

Project description:Atopic dermatitis is a complex disease of heterogeneous pathogenesis, in particular, genetic predisposition, environmental triggers, and their interactions. Indoor air pollution, increasing with urbanization, plays a role as environmental risk factor in the development of AD. However, we still lack a detailed picture of the role of air pollution in the development of the disease. Here, we examined the effect of formaldehyde (FA) exposure on the manifestation of atopic dermatitis and the underlying molecular mechanism in naive rats and in a rat model of atopic dermatitis (AD) produced by neonatal capsaicin treatment. The AD and naive rats were exposed to 0.8 ppm FA, 1.2 ppm FA, or fresh air (Air) for 6 weeks (2 hours/day and 5 days/week). So, six groups, namely the 1.2 FA-AD, 0.8 FA-AD, Air-AD, 1.2 FA-naive, 0.8 FA-naive and Air-naive groups, were established. Pruritus and dermatitis, two major symptoms of atopic dermatitis, were evaluated every week for 6 weeks. After that, samples of the blood, the skin and the thymus were collected from the 1.2 FA-AD, the Air-AD, the 1.2 FA-naive and the Air-naive groups. Serum IgE levels were quantified with ELISA, and mRNA expression levels of inflammatory cytokines from extracts of the skin and the thymus were calculated with qRT-PCR. The dermatitis and pruritus significantly worsened in 1.2 FA-AD group, but not in 0.8 FA-AD, compared to the Air-AD animals, whereas FA didn't induce any symptoms in naive rats. Consistently, the levels of serum IgE were significantly higher in 1.2 FA-AD than in air-AD, however, there was no significant difference following FA exposure in naive animals. In the skin, mRNA expression levels of Th1 cytokines such as TNF-α and IL-1β were significantly higher in the 1.2 FA-AD rats compared to the air-AD rats, whereas mRNA expression levels of Th2 cytokines (IL-4, IL-5, IL-13), IL-17A and TSLP were significantly higher in 1.2 FA-naive group than in the Air-naive group. These results suggested that 1.2 ppm of FA penetrated the injured skin barrier, and exacerbated Th1 responses and serum IgE level in the AD rats so that dermatitis and pruritus were aggravated, while the elevated expression of Th2 cytokines by 1.2 ppm of FA in naive rats was probably insufficient for clinical manifestation. In conclusion, in a rat model of atopic dermatitis, exposure to 1.2 ppm of FA aggravated pruritus and skin inflammation, which was associated with the elevated expression of Th1 cytokines.
