Dupilumab treatment decreases MBC2s, correlating with reduced IgE levels in pediatric atopic dermatitis. J Allergy Clin Immunol 2024:S0091-6749(24)00736-X. [PMID: 39038586 DOI: 10.1016/j.jaci.2024.06.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Revised: 05/23/2024] [Accepted: 06/13/2024] [Indexed: 07/24/2024]
Abstract
BACKGROUND A preference for type 2 immunity plays a central role in the pathogenesis of atopic dermatitis (AD). Dupilumab, an mAb targeting the IL-4 receptor α (IL-4Rα) subunit, inhibits IL-4 and IL-13 signaling. These cytokines contribute significantly to IgE class switch recombination in B cells, critical in atopic diseases. Recent studies indicate IgG+CD23hiIL-4Rα+ type 2 memory B cells (MBC2s) as IgE-producing B-cell precursors, linked to total IgE serum levels in atopic patients. Total IgE serum levels decreased during dupilumab treatment in previous studies. OBJECTIVE We sought to assess the effects of dupilumab treatment in comparison with alternative therapies on the frequency of MBC2s and the correlation to total IgE levels in pediatric patients with AD. METHODS Pediatric patients with AD, participating in an ongoing trial, underwent randomization into 3 treatment groups: dupilumab (n = 12), cyclosporine (n = 12), and topical treatment (n = 12). Plasma samples and PBMCs were collected at baseline (T0) and at 6 months after starting therapy (T6). Flow cytometry was used for PBMC phenotyping, and ELISA was used to assess total IgE levels in plasma. RESULTS Our findings revealed a significant reduction in MBC2 frequency and total IgE levels among patients treated with dupilumab. In addition, a significant correlation was observed between MBC2s and total IgE levels. CONCLUSIONS Systemic blocking of the IL-4Rα subunit leads to a decrease in circulating MBC2 cells and total IgE levels in pediatric patients with AD. Our findings unveiled a novel mechanism through which dupilumab exerts its influence on the atopic signature.

Risk of Developing Hypertension in Atopic Dermatitis Patients Receiving Long-term and Low-dose Cyclosporine: A Nationwide Population-based Cohort Study. Ann Dermatol 2024; 36:112-119. [PMID: 38576249 PMCID: PMC10995617 DOI: 10.5021/ad.23.099] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 11/09/2023] [Accepted: 11/14/2023] [Indexed: 04/06/2024] Open
Abstract
BACKGROUND Cyclosporine (CS) is a first-line immunosuppressive agent used to manage moderate to severe atopic dermatitis (AD). To date, the risk of developing hypertension associated with the long-term use of low-dose CS in AD patients is understudied. OBJECTIVE To determine the cumulative dose-dependent effect of CS on the risk of developing hypertension in patients with AD. METHODS A nationwide population-based retrospective cohort with 1,844,009 AD patients was built from the Korean National Health Insurance System database from 2005 to 2009. A Cox proportional-hazard regression analysis was performed according to patients' CS treatment history adjusted for potential confounders. RESULTS Current use of CS was associated with an increased risk of developing hypertension (adjusted hazard ratio, 4.442; 95% confidence interval, 3.761-5.247). Among the current CS users, a higher cumulative dose of CS (≥39,725 mg) or longer cumulative use of CS (≥182 days), was significantly associated with an increased risk of developing hypertension. CONCLUSION The incidence of CS-associated hypertension is very low when using low-dose treatment regimens for AD. However, the current use or a high cumulative dose of CS for treating patients with AD increases the risk of developing hypertension. Precaution is needed when prescribing CS for long-term treatment of AD.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory disease with a heterogeneous pathogenesis correlated with dysregulation of the immune system and a prevalence of the T2-mediated immune pathway. Recent understanding of the pathogenesis of AD has allowed the development of new drugs targeting different mechanisms and cytokines that have changed the treatment approach. The aim of this review is to update knowledge on the standard of care and recent advancements in the control of skin inflammation. In light of recent guidelines, we report on the clinical efficacy of novel treatments, with special attention to situations where biologics and small molecules are involved.

Abstract
Currently, there are a few detailed guidelines on the overall management of children and adolescents with moderate-severe atopic dermatitis. AD is a complex disease presenting with different clinical phenotypes, which require an individualized and multidisciplinary approach. Therefore, appropriate interaction between primary care pediatricians, pediatric allergists, and pediatric dermatologists is crucial to finding the best management strategy. In this manuscript, members of the Italian Society of Pediatric Allergology and Immunology (SIAIP), the Italian Society of Pediatric Dermatology (SIDerP), and the Italian Society of Pediatrics (SIP) with expertise in the management of moderate-severe atopic dermatitis have reviewed the latest scientific evidence in the field. This narrative review aims to define a pathway to appropriately managing children and adolescents with moderate-severe atopic dermatitis.

Abstract
Itching is prevalent in children with skin disorders and associated with effects on their mood, quality of life, and social functioning. Surprisingly, there are no data on childhood prevalence of pruritus in the general population. The aim of this article is to explore the epidemiology, clinical manifestation, and treatment for itch (pruritus) in the pediatric population (from infancy to adolescence), and to be helpful to primary care physicians who assess and diagnose pediatric patients with itching. In this study, we searched for specific keywords using PubMed and MEDLINE (Ovid) and, then, refined the retrieved searches for each cause and treatment. As a result of reviewing the literature, atopic dermatitis was shown to be the most common cause of itching, especially during infancy and through preschool. Not only skin disorders but also systemic diseases, drugs, and postburn states can predispose an individual to itching in childhood. There are traditional and newly developed treatment modalities for itching in pediatric patients. However, because the pharmacokinetics and pharmacodynamics of childhood are different from those of adults, the medications for itching have to be applied carefully for these age groups. There are many areas to be elucidated regarding the prevalence and objective assessment of pruritus in pediatric patients. Moreover, the safety profiles of medications in the pediatric population need to be better understood. Further studies to investigate itching in childhood are warranted.

Abstract
BACKGROUND Previous studies found conflicting results about the association of atopic dermatitis (AD) with hypertension. OBJECTIVES Determine whether AD and AD severity are associated with hypertension. METHODS A systematic review was performed of published studies in MEDLINE, EMBASE, Scopus, Web of Science, and GREAT databases. At least 2 reviewers conducted title/abstract, full-text review, and data extraction. Quality of evidence was assessed using the Newcastle-Ottawa Scale. RESULTS Fifty-one studies met inclusion criteria; 19 had sufficient data for meta-analysis. AD was associated with higher odds of hypertension compared to healthy controls (increased in 9 of 16 studies; pooled prevalence: 16.4% vs 13.8%; random-effects regression, pooled unadjusted odds ratio [OR][95% confidence interval <CI95>]: 1.16 [1.04-1.30]), but lower odds of hypertension compared to psoriasis (decreased in 5 of 8 studies; 15.4% vs 24.8%; 0.53 [0.37-0.76]). In particular, moderate-severe AD were associated with hypertension compared to healthy controls (increased in 4 of 6 studies; 24.9% vs 14.7%; 2.33 [1.10-4.94]). Hypertension was commonly reported as an adverse-event secondary to AD treatments, particularly systemic cyclosporine A. Limitations include lack of longitudinal studies or individual-level data and potential confounding. CONCLUSIONS AD, particularly moderate-to-severe disease, was associated with increased hypertension compared to healthy controls, but lower odds than psoriasis.

Abstract
BACKGROUND Allergic dermatitis (AD) is a chronic inflammatory skin disease that a variety of immune cells are involved in the progression of AD. Among them, T cells are one of major players of AD pathogenesis. The V-domain Ig suppressor of T cell activation (VISTA) has been reported that it has a potential immunomodulatory for T cell response. OBJECTIVE This study aimed to investigate immunomodulatory of recombinant VISTA-Ig fusion protein in AD mice model. METHODS The model of AD was built with oxazolone (OXA) in BALB/c mice, then VISTA-Ig was used to treat AD by intraperitoneal (IP) injection. The ear thickness was measured by a digital thickness gauge. The ears tissues were collected and subjected to hematoxylin-eosin (H&E) and toluidine blue (TB) staining. The secretion levels of IL-4 and IgE in the serum were measured by enzyme linked immunosorbent assay (ELISA). The mRNA expression levels of inflammatory cytokines (IL-1β, IL-6, IL-12, and INF-γ) in ear tissues were measured using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). RESULTS Treatment with VISTA-Ig successfully alleviated the symptoms of AD, such as erythema, horny substance, and swelling. The infiltration of inflammatory cells was significantly reduced following VISTA-Ig therapy. The secretion levels of IL-4 and IgE in the serum were significantly attenuated following treatment with VISTA-Ig. Additionally, VISTA-Ig observably down-regulated inflammatory cytokines expression in ear tissues. CONCLUSIONS & CLINICAL RELEVANCE Taken together, our results showed that VISTA-Ig possessed the potential to be a novel immunomodulatory candidate drug against AD.

Abstract
Atopic diseases, particularly atopic dermatitis (AD), asthma, and allergic rhinitis (AR) share a common pathogenesis of inflammation and barrier dysfunction. Epithelial to mesenchymal transition (EMT) is a process where epithelial cells take on a migratory mesenchymal phenotype and is essential for normal tissue repair and signal through multiple inflammatory pathways. However, while links between EMT and both asthma and AR have been demonstrated, as we outline in this mini-review, the literature investigating AD and EMT is far less well-elucidated. Furthermore, current studies on EMT and atopy are mostly animal models or ex vivo studies on cell cultures or tissue biopsies. The literature covered in this mini-review on EMT-related barrier dysfunction as a contributor to AD as well as the related (perhaps resultant) atopic diseases indicates a potential for therapeutic targeting and carry treatment implications for topical steroid use and environmental exposure assessments. Further research, particularly in vivo studies, may greatly advance the field and translate into benefit for patients and families.

Abstract
Background Methotrexate (MTX) has been prescribed to suppress atopic dermatitis (AD) symptoms and flares in moderate-to-severe cases. Objective The purpose of this study was to evaluate the therapeutic efficacy and safety of MTX as well as the suppressive activity of MTX to reduce flares in moderate-to-severe AD patients. Methods Patients with moderate-to-severe AD who were treated with MTX at the Chonnam National University Hospital were retrospectively studied. Results Total 102 patients (79 males, 23 females) with a median age of 22.0±10.3 years were studied. The median initial dose of MTX was 10.3±2.6 mg/week, and the MTX-weekly dose was increased by 2.5 to 5 mg at an interval of 2 to 4 weeks to a maximum dose of 17.5±2.7 mg/week. The median maintenance dose was 11.7±2.1 mg/week; the median duration of treatment with MTX was 34.0±38.8 weeks. The initial response was noted after 5.8±3.7 weeks. Of the 102 patients, 60.8% (62/102) showed successful treatment response and 39.2% (40/102) showed mild or no improvement. MTX therapy effectively suppressed the frequency of AD flares by more than 50% in 71.1% (32/45) of the patients who responded among the MTX responders group. The most common adverse events were transient liver abnormality (5.9%, 6/102) and gastrointestinal discomfort (3.9%, 4/102), but no serious adverse events occurred. Conclusion Our results reveal that MTX is a relatively safe drug to control moderate-to-severe AD with satisfactory therapeutic efficacy and inhibitory activity against AD flares.

Abstract
BACKGROUND Over 20 kinds of steroids, tacrolimus ointments, and cyclosporine capsules are usually recommended for the treatment of atopic dermatitis (AD), depending on the symptoms of patients. However, several side effects sometimes occur with the extensive use of these agents for the treatment of pediatric AD patients. The purpose of this study was to explore whether vitamin K2 could be a new immunosuppressive candidate for pediatric patients with AD. METHODS The immunosuppressive efficacy of vitamin K2 was evaluated through a cell-culture procedure using mitogen-activated peripheral blood mononuclear cells (PBMCs) obtained from pediatric AD patients. RESULTS The mean (SD) IC50 value of vitamin K2 for the proliferation of concanavalin A-activated PBMCs was 15.37 (30.05) μmol/L, while the value for tacrolimus was 0.10 (0.28) ng/mL (0.12 (0.35) nmol/L). There was a significant correlation between the IC50 values for vitamin K2 and those for tacrolimus (P = 0.0001, r = 0.8871). However, there was no significant correlation between the IC50 values of vitamin K2 and those of cyclosporine A or methylprednisolone. A significant correlation between the IC50 values of vitamin K2 or tacrolimus and blood eosinophil counts (P = 0.0099, r = 0.7086 and P = 0.0032, r = 0.7722, respectively) was observed. CONCLUSION Vitamin K2 -inhibited T-cell mitogen stimulated proliferation of PBMCs from pediatric AD patients in a dose-dependent manner. The PBMCs from pediatric AD patients were more sensitive to the immunosuppressive efficacy of vitamin K2 than the PBMCs from healthy subjects. The individual immunosuppressive pharmacological efficacy of vitamin K2 and of tacrolimus could be inferred from the blood eosinophil count of pediatric AD patients.

Abstract
Because atopic dermatitis (AD) is a chronic, relapsing disease, treatment requires the use of both active therapy to control flares and preventative maintenance therapy to promote integrity of the skin barrier. In this third of four sections, important clinical considerations for the treatment of pediatric AD are reviewed. Emerging therapies in development for pediatric AD are introduced.

Abstract
BACKGROUND Treatment of atopic dermatitis and psoriasis in children is difficult due to lack of standardized treatment guidelines and few FDA-approved treatment options. Treatments approved for adults may be used off-label in pediatric patients. OBJECTIVE This review evaluates the topical and oral treatment options available, including off-label uses, and provides a basic therapeutic guideline for pediatric atopic dermatitis and psoriasis. METHODS A PubMed review of topical and systemic treatments for pediatric psoriasis and atopic dermatitis with information regarding age, efficacy, dosing, contra-indications, adverse events, and off-label treatments. RESULTS The search identified seven topical and five systemic treatments that are routinely employed to treat pediatric atopic dermatitis and psoriasis. LIMITATIONS Standardized guidelines regarding treatment choice, dosing, and long-term safety are scarce. Reviews may be subject to ascertainment bias. CONCLUSIONS Current treatment guidelines are based on clinical experience and expert advice with few treatments officially approved for atopic dermatitis and psoriasis in children.

Abstract
BACKGROUND Cyclosporine is a useful immunosuppressive agent for achieving disease control in moderate to severe atopic dermatitis in children and adults. However, it carries the potential for nephrotoxicity. Monitoring of drug levels is performed in other patient groups, such as transplant recipients, but is not commonplace in the management of atopic dermatitis. OBJECTIVES To investigate levels of nephrotoxicity associated with cyclosporine use in atopic dermatitis and assess potential correlation with trough levels of cyclosporine. METHODS An electronic search was conducted on MEDLINE, EMBASE, and Cochrane databases for randomized controlled trials and cohort studies assessing the safety profile of cyclosporine compared to placebo or other atopic dermatitis treatments, in adult and pediatric atopic dermatitis patients from 1966 to May 2019. Studies that did not assess renal toxicity were excluded from analysis. RESULTS Thirty-eight trials were included for analysis, excluding 11 that did not assess renal toxicity. Descriptive statistical analysis only was performed, due to the high heterogeneity between study methodologies. Significant renal toxicity was seen in 0%-9% of pediatric participants. Monitoring of trough cyclosporine levels was performed in only 10 of the studies, and their correlation to toxicity or disease activity was not explored. CONCLUSION There is limited evidence in atopic dermatitis regarding trough level monitoring of cyclosporine. Currently, the practice is not commonplace, particularly in pediatrics, and this is reflected in trial methodology. Monitoring may be useful in specific pediatric groups, such as those on multiple concurrent medications, patients with hepatic or renal dysfunction and non-responders to therapy.

Abstract
INTRODUCTION AND OBJECTIVES Atopic dermatitis (AD) is the most common cutaneous inflammatory disease in both adults and children. Although emerging therapeutic approaches are being investigated for the management of pediatric AD, it still needs to be managed with conventional treatments. This consensus document is aimed at providing an update on general management and therapies of pediatric AD, defining practical recommendations for using both topical and systemic agents. MATERIAL AND METHODS A panel of experts consisting of dermatologists and pediatricians were convened in order to define statements, through a Delphi process, standardizing the management of AD in pediatric subjects in a real-world setting. RESULTS A set of practical recommendations obtaining an at least 75% agreement was presented. CONCLUSIONS This set of practical recommendations represents a simple and fast snapshot on the pediatric use of common anti-AD therapeutics.

Abstract
BACKGROUND Atopic dermatitis (AD) is a chronic inflammatory skin disease that typically affects children. Severe forms may have a profound effect on patients' quality of life. Some forms are resistant to conventional treatment and require the use of systemic immunosuppressants such as azathioprine (AZA) to adequately manage the disease. OBJECTIVE To evaluate the effectiveness and tolerance of AZA in children with severe AD. PATIENTS AND METHODS We performed a retrospective study of children with severe AD treated with AZA between January 2007 and May 2017. RESULTS We reviewed the cases of 11 patients (6 boys and 5 girls) with a mean age of 13 years (range, 8-18 years). The mean (SD) age at start of treatment was 10.9 (2.2) years (95% CI 8.6-13.1). The mean initial dosage of AZA was 1.8 (0.2) mg/kg/d. We evaluated treatment response after 4 weeks, 12 to 16 weeks, and 6 months. Mean treatment duration was 10.8 (5.7) months. Treatment had to be suspended in 2 patients because of adverse effects. Seven of the 9 remaining patients presented complete or almost complete clearance of the AD after 6 months of treatment. CONCLUSION In our experience, AZA is well tolerated and may be considered as a treatment option in children with severe AD resistant to conventional treatment.

Abstract
BACKGROUND/OBJECTIVES Nummular eczema in children is a chronic condition characterized by pruritic coin-shaped eczematous lesions that affect any part of the body and often become exudative. Mid- to high-potency topical corticosteroids are considered the mainstay treatment, but there are limited data on the use of systemic therapy for nummular eczema in children. The objective of the current study was to evaluate the efficacy and safety of methotrexate in children with severe nummular eczema. METHODS A retrospective review was undertaken of children with nummular eczema treated with methotrexate between January 2007 and May 2017. RESULTS The records of 28 patients (24 male, 4 female) with a mean age at the beginning of treatment of 7.8 ± 1.6 years (95% confidence interval (CI) = 6.1-9.4 years) were reviewed. The median duration of treatment was 12.6 ± 3.3 months (95% CI = 9.2-16 months), and 14 patients were still undergoing methotrexate therapy at the time of last review. Ten patients (35.7%) had complete or almost complete clearance of eczema (> 90% improvement), 13 (46.4%) had marked improvement (50%-89%), four had mild improvement (< 50%), and one failed methotrexate therapy. Gastrointestinal intolerance (21.4%) and a nonsignificant increase in liver enzymes (17.9%) were the most frequent side effects. No serious adverse events were noted. CONCLUSION Methotrexate is an effective, well-tolerated treatment in children with moderate to severe nummular eczema that has failed to respond to conventional topical therapy.

Abstract
We estimated the pharmacological efficacy of vitamin K1 (VK1 ) and VK2 on the mitogen-activated peripheral blood mononuclear cells (PBMCs) of paediatric atopic dermatitis (AD) patients. VK2 suppressed the in vitro proliferation of T-cell mitogen-activated PBMCs of AD patients. In contrast, VK1 had little effect on the PBMC proliferation. The IL-2 production from the activated PBMCs of AD patients significantly increased (P < .05), while the production significantly decreased by 100 μmol L-1 VK2 (P < .01). In addition, 100 μmol L-1 VK2 reduced the percentage of CD4+ and CD4+CD25+ cells in PBMCs. These results suggest that VK2 can modulate T-cell function in PBMCs of AD patients.

Abstract
In this paper, an investigation into detecting immunosuppressive medicine in aqueous solutions using a spectrometry-based technique is described. Using optical transmissive spectrometry, absorbance measurements in the spectra range from 250 nm to 1000 nm were carried out for different cyclosporine A (CsA) concentrations in aqueous solutions. The experiment was conducted for samples both with and without interferent substances—glucose and sodium chloride. Using a dedicated algorithm, the measured data was analyzed and a high correlation coefficient R² = 0.8647 was achieved. The experiment showed that the described technique allowed for the detection of various CsA concentration levels in a selective, label-free and simple way. This method could be used in medicine, veterinary medicine and laboratory diagnostics.

Abstract
BACKGROUND Viruses are obligate parasites that depend on the cellular machinery of the host to regenerate and manufacture their proteins. Most antiviral drugs on the market today target viral proteins. However, the more recent strategies involve targeting the host cell proteins or pathways that mediate viral replication. This new approach would be effective for most viruses while minimizing drug resistance and toxicity. METHODS Cytomegalovirus replication, latency, and immune response are mediated by the intermediate early protein 2, the main protein that determines the effectiveness of drugs in cytomegalovirus inhibition. This review explains how intermediate early protein 2 can modify the action of cyclosporin A, an immunosuppressive, and antiviral drug. It also links all the pathways mediated by cyclosporin A, cytomegalovirus replication, and its encoded proteins. RESULTS Intermediate early protein 2 can influence the cellular cyclophilin A pathway, affecting cyclosporin A as a mediator of viral replication or anti-cytomegalovirus drug. CONCLUSION Cyclosporin A has a dual function in cytomegalovirus pathogenesis. It has the immunosuppressive effect that establishes virus replication through the inhibition of T-cell function. It also has an anti-cytomegalovirus effect mediated by intermediate early protein 2. Both of these functions involve cyclophilin A pathway.
