Project description:ObjectiveTo evaluate the efficacy and safety of pimecrolimus cream 1% in the treatment of AD in the pediatric population.MethodsPubMed, EMBASE, Web of Science and Cochrane library databases were searched till July 2013. The randomized and nonrandomized blinded studies of pimecrolimus cream 1% applied twice daily with Jaded score ≥ 3 in pediatric patients with AD were included. The efficacy outcomes included investigator global assessment (IGA), eczema area and severity index (EASI) scores, pruritus and care giver's assessments and flares free period. Adverse events were reviewed to assess the safety.ResultsOut of 81 studies, 7 were selected that enrolled 2,170 pediatric patients. The pooled analysis reported that pimecrolimus was no better to vehicle reducing eczema at day-8, day-26 and six weeks (OR 4.95, 95% CI 2.79-8.80), (OR 9.69, 95% CI 4.12-22.83) and (OR 3.83. 95% CI 1.94-7.56), respectively in children. Similarly, pimecrolimus did not show beneficial effects when analyzed for mild or absent pruritus at day 4 (OR 8.29, 95% CI 3.88-17.72 favoring vehicle), day 43 (OR 1.81 95% CI 1.13-2.89 favoring vehicle) and 1 week (OR 2.29, 95%CI 1.45 to 3.60 favoring vehicle) as compared with vehicle. One study comparing pimecrolimus with tacrolimus found no significant difference in achieving mild or absent pruritus (OR 0.94, 95% CI 0.44-1.99). More patients showed an improvement in overall disease in vehicle group at day 8 (OR 3.30, 95% CI 2.03-5.35), day 29 (OR 14.14, 95% CI 6.87-29.13) and day 43 (OR 4.11, 95% CI 2.59-6.52) as compared with pimecrolimus 1% group, as assessed by caregivers. No significant difference was seen between the total AEs in both groups (pimecrolimus vs vehicle/tacrolimus) (OR 1.19, 95% CI 0.85, 1.65).ConclusionThe results of the present meta-analysis showed that pimecrolimus cream 1% was not significantly better to vehicle for AD in pediatrics population.

Project description:Importance:Systemic treatments for severe childhood atopic dermatitis have limited evidence and/or are unlicensed. Despite the efficacy of anti-IgE medication (omalizumab) in the treatment of atopy, no large randomized studies in childhood atopic dermatitis have been published. Objective:To determine the effectiveness of omalizumab in treating severe atopic dermatitis in children. Design, Setting, and Participants:The Atopic Dermatitis Anti-IgE Pediatric Trial (ADAPT) was a 24-week single-center, double-blind, placebo-controlled randomized clinical trial with a 24-week follow-up. Conducted from November 20, 2014, to August 31, 2017, at Guy's and St Thomas' Hospital NHS Foundation Trust and King's College London in the United Kingdom, this trial recruited participants after a screening visit. Eligible participants (n?=?62) were aged 4 to 19 years and had severe eczema (with objective Scoring Atopic Dermatitis [SCORAD] index >40) that was unresponsive to optimum therapy. Statistical analysis was conducted using the intention-to-treat principle. Interventions:Subcutaneous omalizumab or placebo for 24 weeks. The drug manufacturer's dosing tables were used to determine the dosage based on total IgE (30-1500 IU/mL) and body weight (in kilograms) at randomization. Main Outcomes and Measures:Objective SCORAD index after 24 weeks of treatment. Results:In total, 62 children (mean [SD] age, 10.3 [4.2] years; 32 (52%) were male) were randomized to either omalizumab (n?=?30) or placebo (n?=?32). Five participants withdrew from treatment (4 [13%] from the placebo group, and 1 [3%] from the omalizumab group). Follow-up attendance was 97% at week 24 and 98% at week 48. After adjustment for baseline objective SCORAD index, age, and IgE level, the mean difference in objective SCORAD index improvement between groups at week 24 was -6.9 (95% CI, -12.2 to -1.5; P?=?.01), significantly favoring omalizumab therapy and reflecting the results in other assessments of atopic dermatitis severity. Improved quality-of-life scores were seen in the omalizumab group, as measured by the Children's Dermatology Life Quality Index/Dermatology Life Quality Index (-3.5; 95% CI, -6.4 to -0.5) and Pediatric Allergic Disease Quality of Life Questionnaire score (-0.5; 95% CI, -0.9 to -0.0). Improvements in disease severity occurred despite lower potent topical corticosteroid use in the omalizumab group compared with the placebo group (median [interquartile range (IQR)] percentage of body surface area covered, 16% [10%-46%] vs 31% [14%-55%]; median [IQR] number of days of use, 109 [34-164] days vs 161 [82-171] days). Conclusions and Relevance:This randomized clinical trial found that omalizumab significantly reduced atopic dermatitis severity and improved quality of life in a pediatric population with atopy and severe eczema despite highly elevated total IgE levels at baseline. The result was associated with a potent topical corticosteroid sparing effect and may suggest that omalizumab is a treatment option for difficult-to-manage severe eczema in children with atopy. Trial Registration:ClinicalTrials.gov identifier: NCT02300701.

Project description:Therapeutic regimens for the treatment and long-term management of AD traditionally had a two-fold objective of decreasing skin inflammation and repairing the defective skin barrier. Essential treatments for AD in children should include topical moisturizers for skin hydration and prevention of flares, topical anti-inflammatory medications (e.g. corticosteroids, calcineurin inhibitors, PDE4 inhibitor), allergen/irritant avoidance, and treatment of skin infections. Treatment regimens should be severity-based, and implemented in a stepwise approach tailored to the individual patient. This stepwise approach includes initial use of emollients, gentle skin care, and escalating to more potent anti-inflammatory treatments as the disease severity increases. Currently available systemic medications should be reserved for the presence of recalcitrance to topical therapies due to associated toxicities. We believe that early treatment of AD is not only essential in treating the skin disease, but also in preventing the development of additional atopic diseases, such as food allergy, asthma and allergic rhinitis. The defective skin barrier of AD permits a route of entry for food and environmental allergens, and upon exposure, keratinocytes secrete TSLP, which activates the TH2 pathway. This TH2 differentiation sets off the atopic march and the subsequent diseases that are seen. This review highlights treatment options and strategies in pediatric AD therapy with an emphasis on early therapy. Supporting evidence on the efficacy and safety of each intervention will be discussed.

Project description:Background/objectivesPediatricians manage skin conditions such as atopic dermatitis (AD) but report that their dermatologic training is inadequate. Online modules may enhance medical education when sufficient didactic or clinical teaching experiences are lacking. We assessed whether an online module about AD improved pediatric residents' knowledge and changed their clinical management of AD.MethodsTarget and control cohorts of pediatric residents from two institutions were recruited. Target subjects took a 30-question test about AD early in their residency, reviewed the online module, and repeated the test 6 months and 1 year later. The control subjects, who had 1 year of clinical experience but had not reviewed the online module, also took the test. The mean percentage of correct answers was calculated and compared using two-sided, two-sample independent t tests and repeated-measures analysis of variance. For a subset of participants, clinical documentation from AD encounters was reviewed and 13 practice behaviors were compared using the Fisher exact test.ResultsTwenty-five subjects in the target cohort and 29 subjects in the control cohort completed the study. The target cohort improved from 18.0 ± 3.2 to 23.4 ± 3.4 correctly answered questions over 1 year (P < .001). This final value was greater than that of the control cohort (20.7 ± 4.5; P = .01). Meaningful differences in practice behaviors were not seen.ConclusionPediatric residents who reviewed an online module about AD demonstrated statistically significant improvement in disease-specific knowledge over time and had statistically significantly higher scores than controls. Online dermatology education may effectively supplement traditional clinical teaching.

Project description:Atopic dermatitis (AD) is a chronic, pruritic, inflammatory skin disease which predominately affects children and usually clears up during infancy or childhood. However, AD may persist with a chronic relapsing course until adulthood or develop at a later age. AD treatment can often be complicated. Treating moderate-to-severe AD can be challenging: only a few therapeutic options are available, with cyclosporine being the only approved and labeled systemic drug. In the last few years, advances in the knowledge of AD pathogenesis have been made that can provide the basis for developing new topical and systemic drugs. Among them, biologic drugs targeting specific cytokines involved in the development of the disease will probably revolutionize AD therapy. Currently, dupilumab, a monoclonal antibody that binds to the shared alpha chain subunit of the receptors for IL-4 and IL-13, is the only biologic drug licensed for the treatment of AD in adults. However, other biologic drugs that selectively target some key cytokines in AD pathogenesis (IL-13, IL-31, and IL-22) are also being studied. In this review, we discuss all of the biologic drugs that have been studied for AD treatment.

Project description:IntroductionDupilumab is approved to treat moderate-to-severe atopic dermatitis (AD) in several countries in patients as young as 6 years of age. Since its approval, practical issues related to the use of dupilumab for AD have arisen, with particular interest in transitioning from current therapies and managing medication overlap, considerations for special populations of patients with AD, and management of potential adverse events.MethodsThis article aims to review the literature addressing several practical management issues related to dupilumab use for AD and to provide a framework for clinical decision-making in these circumstances and sub-populations. Each statement was reviewed, revised and voted on by authors to provide their level of agreement and degree of uncertainty for each statement.ResultsAn agreement level > 80% was achieved for all of the statements.ConclusionThe expert panel provides statements considering the practical management of patients with AD taking dupilumab to inform clinical decision-making in specific but frequently encountered clinical situations.

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 (AD) is a chronic, inflammatory skin disease with an eczematous rash and itching. Due to undesired adverse effects of traditional systemic treatment, there is still an unmet need for safe and effective long-term therapy for refractory AD. As our understanding of the pathogenesis underlying AD grows, novel treatments targeting specific molecules have been developed. Here, we discuss the efficacy and safety profiles of these drugs in recent clinical trials. Among their adverse effects, of particular note is AD acceleration. Although there is still debate about whether certain adverse reactions can be said to be paradoxical adverse events (PAEs), a wide range of PAEs have been reported during biological treatment for chronic immune-mediated diseases. Close surveillance of novel biologics is crucial to detect new undescribed paradoxical reactions and to shed light on the convoluted pathogenesis of AD.

Project description:BackgroundEnvironmental factors play a major role on atopic dermatitis (AD) which shows a constant rise in prevalence in western countries over the last decades. The Hygiene Hypothesis suggesting an inverse relationship between incidence of infections and the increase in atopic diseases in these countries, is one of the working hypothesis proposed to explain this trend.ObjectiveThis study tested the efficacy and safety of oral administration of the bacterial lysate OM-85 (Broncho-Vaxom®, Broncho-Munal®, Ommunal®, Paxoral®, Vaxoral®), in the treatment of established AD in children.MethodsChildren aged 6 months to 7 years, with confirmed AD diagnosis, were randomized in a double-blind, placebo-controlled trial to receive, in addition to conventional treatment with emollients and topical corticosteroids, 3.5mg of the bacterial extract OM-85 or placebo daily for 9 months. The primary end-point was the difference between groups in the occurrence of new flares (NF) during the study period, evaluated by Hazard Ratio (HR) derived from conditional Cox proportional hazard regression models accounting for repeated events.ResultsAmong the 179 randomized children, 170 were analysed, 88 in the OM-85 and 82 in the placebo group. As expected most children in both treatment groups experienced at least 1 NF during the study period (75 (85%) patients in the OM-85 group and 72 (88%) in the placebo group). Patients treated with OM-85 as adjuvant therapy had significantly fewer and delayed NFs (HR of repeated flares = 0.80; 95% confidence interval (CI): 0.67-0.96), also when potential confounding factors, as family history of atopy and corticosteroids use, were taken into account (HR = 0.82; 95% CI: 0.69-0.98). No major side effect was reported, with comparable and good tolerability for OM-85 and placebo.ConclusionsResults show an adjuvant therapeutic effect of a well standardized bacterial lysate OM-85 on established AD.

Project description:PurposeManagement of atopic dermatitis (AD) typically requires application of topical treatments, often multiple times a day. The cosmetic properties and burdensome application of these treatments can be detrimental to quality of life (QoL). Patients who achieve good disease control through use of systemic therapies may reduce the frequency and amount of topical applications, improving QoL. This study aimed to quantify the utility and disutility for topical AD treatment processes.MethodsSeven vignettes describing different skincare regimens for people with moderate-to-severe AD were developed with input from healthcare professionals. 484 respondents from the general population completed time trade-off items for each vignette. Utility values for each regimen, and disutilities associated with the impact of changes to skincare regimens, were calculated. Analysis of variance assessed differences between skincare regimens.ResultsAs skincare regimens increased in intensity (0.7968 for the most intense; 0.9999 for the least), utility values decreased. There were no statistically significant differences between skincare regimens followed by patients with good disease control (0.9862 to 0.9999); however, when compared to those involving topical corticosteroids and emollient combinations (0.7968 to 0.8835), significant differences were observed (p?<?0.001). The largest disutilities (0.1521 to 0.1705) were between skincare regimens describing the use of topical corticosteroids plus emollient and those followed by patients with good disease control.ConclusionsThe application of topical treatments has a detrimental effect on QoL, which increases with the duration and frequency of applications. Further research is needed to investigate how health and process utilities interact and both can be integrated into medical decision-making.
