Chang YC, Wu MC, Wu HJ, Liao PL, Wei JCC. Prenatal and early-life antibiotic exposure and the risk of atopic dermatitis in children: A nationwide population-based cohort study. Pediatr Allergy Immunol 2023; 34:e13959. [PMID: 37232285 DOI: 10.1111/pai.13959] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2022] [Revised: 04/20/2023] [Accepted: 04/24/2023] [Indexed: 05/27/2023]
Abstract
BACKGROUND Atopic dermatitis (AD) contributes to substantial social and financial costs in public health care systems. Antibiotic exposure during pregnancy has been proposed as a risk factor, but findings remain inconsistent. The aim of this study was to investigate the association between prenatal antibiotic use and childhood AD. METHODS We performed a population-based cohort study using data collected from the Taiwan Maternal and Child Health Database from 2009 to 2016. Associations were determined using Cox proportional hazards model and were adjusted for several potential covariates, including maternal atopic disorders and gestational infections. Children with and without maternal predispositions of atopic diseases and postnatal antibiotic/acetaminophen exposures within 1 year were stratified to identify the subgroups at risk. RESULTS A total of 1,288,343 mother-child pairs were identified and 39.5% received antibiotics prenatally. Maternal antibiotic use during pregnancy was slightly positively associated with childhood AD (aHR 1.04, 95% CI 1.03-1.05), especially in the first and second trimesters. An apparent dose-response pattern was observed with an 8% increased risk when the exposure was ≥5 courses prenatally (aHR 1.08, 95% CI 1.06-1.11). Subgroup analysis showed the positive association remained significant regardless of postnatal infant antibiotic use, but the risk attenuated to null in infants who were not exposed to acetaminophen (aHR 1.01, 95% CI 0.96-1.05). The associations were higher in children whose mothers were without AD compared to those whose mothers were with AD. In addition, postnatal antibiotic or acetaminophen exposure of infants was associated with an increased risk of developing AD after 1 year of age. CONCLUSION Maternal antibiotic use during pregnancy was associated with an increased risk of childhood AD in a dose-related manner. Further research may be warranted to investigate this variable using a prospectively designed study, and also to examine whether or not this association is specifically related to pregnancy.

World J Clin Cases 2022; 10:166-176. [PMID: 35071516 PMCID: PMC8727240 DOI: 10.12998/wjcc.v10.i1.166] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Revised: 10/29/2021] [Accepted: 11/28/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Tissue resident memory T (TRM) cells have been reported to play a significant role in the pathogenesis and relapse of chronic eczema.
AIM To compare the efficacy and safety of the intralesional injection of 5-fluorouracil (5-FU) and triamcinolone (TA) with those associated with TA alone for the treatment of chronic eczema.
METHODS A total of 168 patients were randomized to 5-FU+TA or TA groups and received a one-time intralesional injection of 5-FU+TA or TA only. Biopsies were collected before and 2 wk after treatment for evaluation of histopathological changes. All patients were followed up monthly for up to 1 year.
RESULTS No serious adverse event was observed in either group. Although the mean atopic dermatitis severity index scores and effective rates were comparable between the two groups after 2 wk of treatment, the relapse rate was significantly lower in the 5-FU+TA group than in the TA group. Histological examination showed significantly fewer CD8+ and CD103+ T cells but not CD4+ T cells in the 5-FU+TA group.
CONCLUSION One-time intralesional injection of 5-FU+TA is effective and safe for chronic eczema treatment and can further reduce the retention of TRM cells in the lesional skin and the relapse rate of chronic eczema.

Abstract
Atopic eczema (AE) is an inflammatory skin disease with involvement of genetic, immunological and environmental factors. One hallmark of AE is a skin barrier disruption on multiple, highly interconnected levels: filaggrin mutations, increased skin pH and a microbiome dysbiosis towards Staphylococcus aureus overgrowth are observed in addition to an abnormal type 2 immune response. Extrinsic factors seem to play a major role in the development of AE. As AE is a first step in the atopic march, its prevention and appropriate treatment are essential. Although standard therapy remains topical treatment, powerful systemic treatment options emerged in the last years. However, thorough endotyping of the individual patients is still required for ideal precision medicine approaches in future. Therefore, novel microbial and immunological biomarkers were described recently for the prediction of disease development and treatment response. This review summarizes the current state of the art in AE research.

Abstract
OBJECTIVE To identify the factors associated with the development of skin allergies in the first year of life in moderate and late preterm infants. METHOD This is a cross-sectional study with 151 moderate and late preterm infants, born between May 2016 and May 2017. Participants were evaluated in the 3rd, 6th, 9th and 12th months of life, in telephone interviews. Statistical analyzes were performed in the SPSS software with frequency comparison tests and logistic regression. RESULTS The prevalence of skin allergy, in the perception of caregivers, among late and moderate preterm infants was 16%. Factors such as being admitted to neonatal intensive care (p = 0.006) and not being breastfed (p = 0.041) showed a significant association with the development of skin allergies in the 3rd and 12th months of life, respectively. CONCLUSION Skin allergy, in the perception of caregivers, is more severe in newborn infants who have clinical respiratory and gastrointestinal manifestations, be it conditioning or cause-effect. Breastfeeding proved to be a protective factor in the first year of life.

Abstract
Atopic dermatitis (AD) is a common inflammatory skin disease characterized by intense pruritus and recurrent eczematous lesions that significantly impair quality of life. It is a heterogeneous disease affecting both children and adults. The treatment of moderate-to-severe forms of AD is challenging, as topical corticosteroids are often insufficient to achieve disease control or inappropriate and off-label use of immunosuppressants may have significant undesirable side effects. The development of targeted biologic therapies specifically for AD is thus highly desirable. Dupilumab is the only biologic therapy that is Food and Drug Administration approved for the treatment of moderate-to-severe AD in patients 6 years and older, with consistent long-term efficacy and safety trial data. In this article, we review the mechanisms, safety, and efficacy of dupilumab from recent clinical trials, and we review the current data, mechanism of action, clinical efficacy, and limitations of new biologics currently in phase 2 and 3 clinical trials (lebrikizumab, tralokinumab, nemolizumab, tezepelumab, and ISB 830).

Abstract
Atopic dermatitis (AD) is a chronic inflammatory disease with increasing global incidence, which has a multifactorial pathogenesis and a variable expressivity. Clinical features of AD are different in adults compared to children, but it is well recognized the substantial impact of the disease on patients' quality of life at any age. Indeed, little is known about AD in adolescence, a period of life generally associated with high psychological burden and vulnerability to depression. Guidelines for the management of AD are available for both children and adults but specific guidelines for the diagnosis and treatment of AD in adolescents are lacking. Seven Italian scientific societies of dermatologists, allergists, and pediatric allergists joined in a specific meeting to provide practical guidance for the diagnosis and management of moderate-to-severe adolescent AD suitable for the Italian clinical practice. Through a modified Delphi procedure, consensus was reached by 59 Italian experts in the management of AD on 20 statements covering five areas of interest about adolescent AD, including disease complexity, burden and social impact, diagnosis and definition of severity, current treatments, and new biologic therapies. This paper reports recommendations for the diagnosis and management of AD specifically in adolescents, pointing out some peculiar clinical features and focusing on the choice of medications. Dupilumab, the first biologic approved for the treatment of adolescents with AD, represents a useful treatment option due to its efficacy and reassuring safety profile.
