A mouse model of AD was established using the semiantigen 2,4-dinitrofluorobenzene induction method. The lesion scores, transepidermal water loss and p H, and skin histopathology of mice in each group were observed. The expressions of filaggrin, loricrin,and involucrin were detected by the streptavidin peroxidase immunohistochemical method and western blotting, and their mRNA expressions were detected by quantitative polymerase chain reaction.Results: Mice in the WF, ERF, ICF, and PC groups showed reduced skin lesion performance, improved histopathology, decreased skin lesion score, transepidermal water loss and pH, and upregulated expressions of proteins including filaggrin, loricrin, and involucrin, and their mRNAs. The most obvious regulatory effect was observed in the WF group, followed by the ICF, ERF, and PC groups, accordingly.Conclusions: Mahuang Lianqiao Chixiaodou decoction and its disassembled formula can improve the skin barrier function in a mouse model of AD by upregulating filaggrin, loricrin, and involucrin, and their mRNA expressions, and the most optimal effect was noted in the WF group, followed by the ICF and ERF groups, which suggests that the effect of clearing heat and resolving dampness in improving the skin barrier function of AD is more obvious and is one of the key treatments for AD.展开更多

摘要Atopic dermatitis(AD),which is associated with inflammatory response and skin damage,is increasing worldwide in recent years.Interest is increasing in the protective effects of natural and fermented products on the prevention and treatment of AD.This study aimed to investigate the ameliorative effects of a new rice milk product fermented with Saccharomyces cerevisiae on AD mice.Fermented rice milk could effectively attenuated the symptoms of AD mice,such as skin lesions,scaliness and lichenification.Furthermore,fermented rice milk decreased the levels of inflammatory cytokines interleukin(IL)-4,IL-6 and tumor necrosis factor(TNF)-αin 2,4-dinitrochlorobenzene(DNCB)induced mice.It was also observed that fermented rice milk treatment downregulated the levels of p-IKBα,p-NF-κB,p-ERK,p-JNK and p-p38 proteins expression in skin of AD mice,which showed the anti-inflammatory function of fermented rice milk,mainly via the NF-κB and MAPK signaling pathways.In addition,S.cerevisiae fermentation reduced original flavor of rice milk,and increased the acid and alcohol compounds.Overall,the findings indicated that S.cerevisiae fermentation improved the flavor characteristics of rice milk,and fermented rice milk exhibited protective effects against DNCB-induced atopic dermatitis by downregulating NF-κB and MAPK signaling pathways and protecting the skin barrier.
摘要Objective:Patients with moderate-to-severe atopic dermatitis(AD)often experience intense pruritus and extensive skin lesions,which markedly impair quality of life.Current treatment options,including biologics and small-molecule agents,may provide limited efficacy and are associated with adverse effects.For patients who respond inadequately to dupilumab,particularly those with insufficient control of pruritus,more effective therapeutic strategies are needed.This study aims to evaluate the efficacy,safety,and clinical value of combining dupilumab with Janus kinase inhibitors(JAKis)in the treatment of refractory AD.Methods:This retrospective study assessed the efficacy and safety of combination therapy with dupilumab and JAKis in 7 patients with refractory moderate-to-severe AD.Patients received either abrocitinib(100 mg/d)or upadacitinib(15 mg/d)in combination with dupilumab.Disease severity before and after combination therapy was evaluated using the Eczema Area and Severity Index(EASI),Scoring Atopic Dermatitis(SCORAD),Patient-Oriented Eczema Measure(POEM),Dermatology Life Quality Index(DLQI),Itch Numerical Rating Scale(Itch-NRS),and Sleep Disorder Numerical Rating Scale(Sleep-NRS).Adverse events were also recorded.Results:After 4 weeks of combination therapy,patients with AD who had shown an inadequate response to dupilumab monotherapy exhibited marked improvement in skin lesions.Significant reductions were observed in EASI,SCORAD,POEM,DLQI,Itch-NRS,and Sleep-NRS scores(all P<0.05).All patients achieved an EASI50(defined as≥50%reduction in EASI score from baseline)criteria.No serious adverse events were reported,except for one case of mild acne.Conclusion:In patients with AD who show an inadequate response to continued dupilumab treatment,the addition of JAKis can significantly enhance therapeutic efficacy and is generally well tolerated.This combination regimen may represent a promising treatment option for refractory AD.
摘要Atopic dermatitis(AD)is a chronic,relapsing inflammatory skin disorder that is highly prevalent in children.Because of its pathogenesis and clinical heterogeneity,exclusive use of pharmacological treatment cannot achieve the optimal control of AD.This consensus therefore endorses non-pharmacological interventions as essential components of comprehensive AD management.The recommendations emphasize the avoidance of environmental triggering factors,the maintenance and restoration of skin barrier homeostasis via structured skincare,and the implementation of patient/caregiver education and psychological support.These measures aim not only to reduce relapse frequency and extent clinical remissions,but also to improve the quality of life for patients and caregivers.The consensus offers four core recommendations:(1)Non-pharmacological interventions should be employed as primary management strategies across the spectrum of AD severity,from mild to severe disease.(2)Effectiveness of the interventions should be assessed through clinical and medical evaluation,with supplemental objective or laboratory measurements when feasible.(3)Primary interventions include systematic avoidance of environmental triggers,regular application of skin care,and structured programs for education and psychological support.(4)Non-pharmacological strategies are applicable at all stages of disease,from prevention to active flares and clinical remissions.

摘要Background:Wenqing Yin(WQY)is a classic prescription used to treat skin diseases like atopic dermatitis(AD)in China,and the aim of this study is to investigate the therapeutic effects and molecular mechanisms of WQY on AD.Methods:The DNFB-induced mouse models of AD were established to investigate the therapeutic effects of WQY on AD.The symptoms of AD in the ears and backs of the mice were assessed,while inflammatory factors in the ear were quantified using quantitative real-time-polymerase chain reaction(qRT-PCR),and the percentages of CD4+and CD8+cells in the spleen were analyzed through flow cytometry.The compounds in WQY were identified using ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)analysis and the key targets and pathways of WQY to treat AD were predicted by network pharmacology.Subsequently,the key genes were tested and verified by qRT-PCR,and the potential active components and target proteins were verified by molecular docking.Results:WQY relieved the AD symptoms and histopathological injuries in the ear and back skin of mice with AD.Meanwhile,WQY significantly reduced the levels of inflammatory factors IL-6 and IL-1βin ear tissue,as well as the ratio of CD4+/CD8+cells in spleen.Additionally,a total of 142 compounds were identified from the water extract of WQY by UPLC-Orbitrap-MS/MS.39 key targets related to AD were screened out by network pharmacology methods.The KEGG analysis indicated that the effects of WQY were primarily mediated through pathways associated with Toll-like receptor signaling and T cell receptor signaling.Moreover,the results of qRT-PCR demonstrated that WQY significantly reduced the mRNA expressions of IL-4,IL-10,GATA3 and FOXP3,and molecular docking simulation verified that the active components of WQY had excellent binding abilities with IL-4,IL-10,GATA3 and FOXP3 proteins.Conclusion:The present study demonstrated that WQY effectively relieved AD symptoms in mice,decreased the inflammatory factors levels,regulated the balance of CD4+and CD8+cells,and the mechanism may be associated with the suppression of Th2 and Treg cell immune responses.

摘要Atopic dermatitis(AD)is the most common chronic inflammatory skin condition.It has significant socioeconomic consequences and complex pathophysiology,necessitating updated management guidelines that consider the age,sex and geographic location of patients.Despite the widespread use of Western medicine(WM),including topical corticosteroids,as the primary treatment for AD,the possible negative effects of WM therapies are inescapable.Although there is still a lack of strong evidence,the integration of traditional Chinese medicine(TCM)with WM may yield a more favorable therapeutic response for AD than WM alone,due to the synergistic effects involved.Balancing the application of diagnostic and therapeutic approaches from TCM and WM is crucial for the management of AD,enhancing treatment efficacy for patients,and averting disease recurrence.In 2025,a new clinical guideline for the diagnosis and treatment of AD was released;it emphasized the integration of TCM with WM.This guideline is crucial as it consolidates global expertise and data to provide a standardized framework for the practical integration of techniques to bridge divides among clinical disciplines.As more substantial data emerge,the development and enhancement of integrative medicine for AD management should be prioritized globally,particularly in Asian regions.
摘要BACKGROUND Atopic dermatitis(AD)is a long-term inflammatory skin disease that requires prolonged management with systemic therapy.Treatment with lebrikizumab results in apoptosis of effector T helper 2 cells that produce interleukin-13.AIM To conduct a systematic literature review on the comparative efficacy of lebrikizumab monotherapy vs other approved biologics and the short-term efficacy of Janus kinase inhibitors in moderate-to-severe AD in adults and adolescents.METHODS A systematic database search was conducted to identify randomized,double-blind,placebo-controlled phase 2 and phase 3 trials of lebrikizumab,dupilumab,tralokinumab,abrocitinib,baricitinib,and upadacitinib used as monotherapy,from database inception through December 2025.Efficacy measurements comprised Eczema Area and Severity Index(EASI)responses,Investigator Global Assessment(IGA)0/1,and pruritus Numeric Rating Scale improvements.Two independent reviewers screened studies,and inter-reviewer agreement was assessed using Cohen's kappa statistic.The Cochrane Risk of Bias tool and the Grading of Recommendations Assessment,Development and Evaluation system assessed the quality of the evidence,with data extraction performed by independent reviewers.RESULTS A total of 28 studies with 10847 patients were evaluated(22 from the previous review and six new studies).The level of agreement among reviewers for study selection was substantial,with a kappa statistic of 0.89.Dosing intervals are reported as every 2 weeks(Q2W).According to 22 trials of network meta-analysis,lebrikizumab 250 mg Q2W was as effective as dupilumab 300 mg Q2W for IGA 0/1.There was an equal improvement in EASI and itch score at weeks 12-16.Lebrikizumab was more efficacious than tralokinumab and baricitinib on outcomes.A total of 2316 patients were included in six new studies designed to confirm these results in real-world evidence settings 2024-2025,with EASI-75 and IGA 0/1 response rates of 65%-78%and 58%-72%,respectively.Data on a two-year extension demonstrated sustained efficacy and acceptable safety.The risk of bias generally resulted in moderate-quality evidence.CONCLUSION An updated review of 28 studies shows that lebrikizumab is at least as efficacious as dupilumab and more efficacious than tralokinumab in moderate-to-severe AD.There is real-world and long-term data to support its first-line use with moderate to high certainty,but complete,736 trials,head-to-head trials,and biomarker research remain needed.

摘要Objective:To assess the safety and topical efficacy of prim-O-glucosylcimifugin(POG)and investigate the molecular mechanisms of its therapeutic effects in atopic dermatitis(AD).Methods:The effects of POG on human keratinocyte cell viability and its anti-inflammatory properties were evaluated using cell counting kit-8 assay and reverse transcription-quantitative polymerase chain reaction(RT-qPCR).Subsequently,the impact of POG on the differentiation of cluster of differentiation(CD)4~+T cell subsets,including T-helper type(Th)1,Th2,Th17,and regulatory T(Treg),was examined through in vitro experiments.Network pharmacology analysis was used to elucidate POG's therapeutic mechanisms.Furthermore,the therapeutic potential of topically applied POG was further evaluated in a calcipotriol-induced mouse model of AD.The protein and transcript levels of inflammatory markers,including cytokines,lymphocyte-specific protein tyrosine kinase(Lck)mRNA,and LCK phosphorylation(p-LCK),were quantified using immunohistochemistry,RT-qPCR,and Western blot analysis.Results:POG was able to suppress cell proliferation and downregulate the transcription of interleukin 4(Il4)and Il13 mRNA.In vitro experiments indicated that POG significantly inhibited the differentiation of Th2 cells,whereas it exerted negligible influence on the differentiation of Th1,Th17 and Treg cells.Network pharmacology identified LCK as a key therapeutic target of POG.Moreover,the topical application of POG effectively alleviated skin lesions in the calcipotriol-induced AD mouse models without causing pathological changes in the liver,kidney or spleen tissues.POG significantly reduced the levels of Il4,Il5,Il13,and thymic stromal lymphopoietin(Tslp)m RNA in the AD mice.Concurrently,POG enhanced the expression of p-LCK protein and Lck mRNA.Conclusion:Our research revealed that POG inhibits Th2 cell differentiation by promoting p-LCK protein expression and hence effectively alleviates AD-related skin inflammation.
摘要BACKGROUND Atopic dermatitis(AD)is a chronic inflammatory skin disease characterized by visible lesions that can lead to anxiety and depression.These psychological impacts may severely affect the physical and mental health and the overall quality of life of the affected individuals.AIM To identify the risk factors for anxiety and depression among patients with AD and to assess their influence on prognosis.METHODS A cross-sectional study was conducted in 273 patients with AD who visited Shanghai Jinshan Tinglin Hospital between July 2021 and June 2023.Data were collected using standardized instruments,including the general information questionnaire,hospital anxiety and depression scale,scoring AD index,and dermatology life quality index.RESULTS Among the evaluated patients,24.5%had symptoms of anxiety,and 19.8%had symptoms of depression.Independent risk factors for anxiety included lower education level[odds ratio(OR)=0.338,95%confidence interval(CI):0.183-0.625],increased number of medical visits(OR=2.300,95%CI:1.234-4.255),sleep disorders(OR=2.013,95%CI:1.032-3.923),and allergic rhinitis(OR=2.052,95%CI:1.097-3.839).Factors for depression included more severe pruritus(OR=6.837,95%CI:1.330-35.132),higher number of medical visits(OR=2.979,95%CI:1.430-6.205),sleep disorders(OR=2.245,95%CI:1.033-5.024),and asthma(OR=2.208,95%CI:1.003-4.859).Dermatology life quality index scores correlated positively with anxiety,depression,scoring AD index,sleep disorders,number of visits,and intensity of pruritus(P<0.05).CONCLUSION In patients with AD,anxiety and depression are associated with educational level,frequency of medical visits,sleep disorders,allergic rhinitis,pruritus,and asthma,all of which exacerbate symptoms and reduce quality of life.
摘要Vitamin D,beyond its classical role in calcium homeostasis,has emerged as a key regulator of immune function and epithelial barrier integrity.Its deficiency during early childhood—a critical period for immune maturation—has been increasingly implicated in the development of atopic diseases.While extensively studied in asthma,its role in non-respiratory allergic conditions such as atopic dermatitis(AD)and allergic rhinitis(AR)remains comparatively underexplored.This minireview synthesizes current mechanistic and clinical evidence on vitamin D in pediatric AD and AR.In AD,vitamin D promotes epidermal barrier function through upregulation of filaggrin and ceramide synthesis,and enhances antimicrobial defense via induction of antimicrobial peptides.Observational studies consistently report lower serum 25-hydroxyvitamin D in affected children,particularly those with allergic sensitization.Select randomized controlled trials suggest clinical improvement with supplementation,especially at doses>2000 IU/day in deficient individuals.In AR,epidemiological data indicate stronger inverse associations with seasonal(pollen-induced)disease.Proposed mechanisms include modulation of dendritic cells,regulatory T cells,T helper 2 cytokines,and mucosal barrier integrity.The shared immunopathogenesis of AD and AR underscores vitamin D’s relevance.Although promising,clinical evidence remains heterogeneous.Future research should prioritize phenotype-stratified trials to clarify optimal dosing,timing,and individual response determinants,including genetics and microbiome composition.
摘要Objective:This study aimed to investigate the association of atopic dermatitis(AD)and anxiety/depression behaviors induced by AD with the intestinal microbiota.Additionally,it sought to evaluate the therapeutic potential of mannan oligosaccharide(MOS)in alleviating AD symptoms through the modulation of the gut microbiota and the enhancement of short-chain fatty acids(SCFAs)production.Methods:Female Kunming mice were challenged with 2,4-dinitrofluorobenzene(DNFB)to induce AD-like symptoms.MOS was administered orally daily for 14 days.On the 6th and 11th days post-modeling,the number of scratching bouts in mice was recorded.Following dissection,epidermal thickness,mast cell infiltration,and serum levels of inflammatory cytokines were measured.Meanwhile,cerebral levels of neurotransmitters,including 5-hydroxytryptamine(5-HT)and norepinephrine(NE),were assessed.The abundance of intestinal microbiota and fecal concentrations of SCFAs were also analyzed.Results:MOS significantly reduced AD-like symptoms by reducing inflammatory cytokines,as reflected in a significant decrease in the number of scratching bouts,epidermal thickness,mast cells and inflammatory cytokine levels.MOS intervention up-regulated the expression of 5-HT and NE,and consequently alleviated anxiety and depression-like behaviors.Furthermore,compared with the AD group,MOS intervention increased the gut microbiota abundance of mice,especially beneficial bacteria such as Bifidobacterium,Lactobacillus and Klebsiella.At the same time,these beneficial bacteria significantly increased the fecal contents of SCFAs,especially propionic acid.Correlation analysis indicated that AD amelioration was positively correlated with fecal SCFAs levels and the proliferation of certain intestinal microbes.Conclusion:MOS intervention could offer a novel approach to managing AD and its psychological comorbidities.

摘要Atopic dermatitis(AD)is one of the most common chronic inflammatory skin diseases.It usually develops in childhood and may persist into adulthood.Dupilumab is a fully human monoclonal antibody directed against interleukin-4R-alpha,the common chain of interleukin-4 and interleukin-13 receptors.Dupilumab showed clinical improvements in patients with atopic dermatitis,asthma,and chronic rhinosinusitis and is currently under development for other indications.However,there are many adverse effects reported after dupilumab therapy including local injection site reactions,conjunctivitis,headache,and nasopharyngitis.We report a new case of a 4-year-old child who experienced anaphylaxis after dupilumab injection.In addition to,we summary and disscuss the rare adverse reactions caused by dupilumab injection by searching the literature in pubmed.
摘要BACKGROUND Atopic dermatitis(AD),or eczema,is a chronic,pruritic inflammatory skin disease affecting children and adults.Socioeconomic status(SES)plays a significant role in developing AD.However,mixed evidence from a previous study by Bajwa et al makes it difficult to determine the directionality of the association.There is a lite-rature gap in understanding the causal association between AD and socioeco-nomic factors.AIM To evaluate the impact of disparities in SES on pediatric AD populations.METHODS Based on the eligibility criteria,the literature review identified eight articles since July 2021,and a descriptive analysis was conducted using an Excel spreadsheet on key components collected from the identified studies.RESULTS Eight observational studies assessed SES in pediatric AD.Five observational studies showed mixed associations between AD and SES.Sub-analysis revealed that urban areas had a higher prevalence of AD,and four studies identified a positive association between parental education and AD in the pediatric popu-lation.Socioeconomic variables,such as residential areas and household income,significantly influence disease outcomes.CONCLUSION There is mixed association between pediatric AD and SES,with AD positively associated with parental education.There is critical need to evaluate global impact of SES variables on pediatric AD.

摘要Objective Atopic dermatitis(AD)is a chronic inflammatory skin disease that may be linked to changes in the gut microbiome.Acupuncture has been proven to be effective in reducing AD symptoms without serious adverse events,but its underlying mechanism is not completely understood.The purpose of this study was to investigate whether the potential effect of acupuncture on AD is gut microbiota-dependent.Methods AD-like skin lesions were induced by applying MC903 topically to the cheek of the mouse.Acupuncture was done at the Gok-Ji(LI11)acupoints.AD-like symptoms were assessed by lesion scores,scratching behavior,and histopathological changes;intestinal barrier function was measured by fecal output,serum lipopolysaccharide levels,histopathological changes,and mRNA expression of markers involved in intestinal permeability and inflammation.Gut microbiota was profiled using 16S rRNA gene sequencing from fecal samples.Results Acupuncture effectively improved chronic itch as well as the AD-like skin lesions with epidermal thickening,and also significantly altered gut microbiota structure as revealed byβ-diversity indices and analysis of similarities.These beneficial effects were eliminated by antibiotic depletion of gut microbiota,but were reproduced in gut microbiota-depleted mice that received a fecal microbiota transplant from acupuncture-treated mice.Interestingly,AD mice had intestinal barrier dysfunction as indicated by increased intestinal permeability,atrophy of the mucosal structure(reduced villus height and crypt depth),decreased expression of tight junctions and mucus synthesis genes,and increased expression of inflammatory mediators in the ileum.Acupuncture attenuated these abnormalities,which was gut microbiota-dependent.Conclusion Acupuncture ameliorates AD-like phenotypes in a gut microbiota-dependent manner and some of these positive benefits are explained by modulation of the intestinal barrier,providing new perspective for non-pharmacological strategies for modulating gut microbiota to prevent and treat AD.
摘要BACKGROUND Lichen amyloidosis(LA)is a chronic,severely pruritic skin disease,which is the most common form of primary cutaneous amyloidosis.The treatment of LA has been considered to be difficult.LA may be associated with atopic dermatitis(AD),and in this setting,the treatment options may be more limited.Herein,we report four cases of LA associated with AD successfully treated by dupilumab.CASE SUMMARY In this article,we describe four cases of patients who presented with recurrent skin rash accompanied by severe generalized intractable pruritus,diagnosed with refractory LA coexisting with chronic AD.Previous treatments had not produced any apparent improvement.Thus,we administered dupilumab injection subcutaneously at a dose of 600 mg for the first time and 300 mg every 2 wk thereafter.Their lesions all markedly improved.CONCLUSION Dupilumab may be a new useful treatment for LA coexisting with AD.

摘要Objective: To reveal the mechanism of Mahuang Lianqiao Chixiaodou decoction and its disassembled formula for improving the skin barrier function in a mouse model of atopic dermatitis(AD).Methods: Sixty specific-pathogen free male BALB/c mice were randomly divided into the control group,model group, whole formula group(WF), exterior-releasing formula group(ERF), interior-clearing formula group(ICF), and positive control group(PC). A mouse model of AD was established using the semiantigen 2,4-dinitrofluorobenzene induction method. The lesion scores, transepidermal water loss and p H, and skin histopathology of mice in each group were observed. The expressions of filaggrin, loricrin,and involucrin were detected by the streptavidin peroxidase immunohistochemical method and western blotting, and their mRNA expressions were detected by quantitative polymerase chain reaction.Results: Mice in the WF, ERF, ICF, and PC groups showed reduced skin lesion performance, improved histopathology, decreased skin lesion score, transepidermal water loss and pH, and upregulated expressions of proteins including filaggrin, loricrin, and involucrin, and their mRNAs. The most obvious regulatory effect was observed in the WF group, followed by the ICF, ERF, and PC groups, accordingly.Conclusions: Mahuang Lianqiao Chixiaodou decoction and its disassembled formula can improve the skin barrier function in a mouse model of AD by upregulating filaggrin, loricrin, and involucrin, and their mRNA expressions, and the most optimal effect was noted in the WF group, followed by the ICF and ERF groups, which suggests that the effect of clearing heat and resolving dampness in improving the skin barrier function of AD is more obvious and is one of the key treatments for AD.
