Impact of Overweight on Response to Dupilumab Treatment in Chronic Rhinosinusitis with Nasal Polyps. Nutrients 2024; 16:2982. [PMID: 39275297 PMCID: PMC11397523 DOI: 10.3390/nu16172982] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2024] [Revised: 08/29/2024] [Accepted: 09/03/2024] [Indexed: 09/16/2024] Open
Abstract
Chronic rhinosinusitis with nasal polyps (CRSwNP) significantly impacts quality of life and often presents therapeutic challenges, with biologics like dupilumab showing promise in managing severe, uncontrolled cases. The aim of this study was to assess the influence of overweight on the effectiveness of dupilumab in patients with uncontrolled CRSwNP. This retrospective study analyzed treatment outcomes of 75 CRSwNP patients receiving dupilumab, categorizing them into underweight/normal-weight (BMI ≤ 24.9 kg/m2) and overweight/obese (BMI ≥ 25 kg/m2) groups. Outcome measures included changes in nasal polyp score (NPS) and sinonasal outcome test (SNOT-22) scores. Results demonstrated that the underweight/normal-weight group experienced significantly greater improvements in NPS and a higher rate of total NPS improvement compared to the overweight/obese group. While SNOT-22 scores improved in both groups, no significant differences were observed. Among patients with comorbid asthma, the underweight/normal-weight subgroup also showed significantly better outcomes, including greater reductions in both NPS and SNOT-22 scores. Multiple regression analysis identified BMI as an independent prognostic factor for NPS outcomes. The findings suggest that overweight/obesity adversely affects the response to dupilumab in CRSwNP, emphasizing the need for personalized treatment strategies considering BMI.

Abstract
BACKGROUND Long-term daily practice data on patient-reported benefits of dupilumab for atopic dermatitis (AD) remains limited. OBJECTIVE To evaluate patient-reported outcome measures (PROMs) and the safety of dupilumab in patients with moderate-to-severe AD over a follow-up period of up to 5 years. METHODS Data were extracted from the prospective, multicenter BioDay registry (October 2017-2022) of patients with moderate-to-severe AD treated with dupilumab in daily practice. RESULTS In total 1223 patients, 1108 adults and 115 pediatric patients were included. After ≥1 year of treatment, mean Patient-Oriented Eczema Measure (POEM), Dermatology Life Quality Index (DLQI), Numeric rating scale (NRS)-pruritus ranged between 7.8 and 8.7, 3.5 and 4.2, and 2.9 and 3.1 in adults, respectively, whilst these patient-reported outcome measures (PROMs) ranged between 8.9 and 10.9, 4.4 and 6.4, and 3.0 and 3.7 in pediatric patients, respectively. At follow-up, overall work impairment decreased from 40.1% to 16.3% to 13.3% in adults. Furthermore, class I obesity and itch-dominant patients generally had less favorable treatment response. Of all patients, 66.8% reported ≥1 adverse event, with conjunctivitis being the most common (33.7%). LIMITATIONS The overall percentage of missing values for selected PROMs was 26% in adults and 46% in pediatric patients. CONCLUSION In addition to favorable safety, dupilumab has demonstrated sustained effectiveness across various PROMs, underscoring the treatment benefits from patients' perspectives.

Abstract
BACKGROUND Dupilumab has shown to be an effective and safe treatment for patients with moderate-to-severe atopic dermatitis (AD). OBJECTIVE To evaluate the predictive factors of response (PRF) in patients with moderate-to-severe AD treated with dupilumab. METHODS Observational, retrospective and multicentre study conducted on adult patients diagnosed with moderate-to-severe AD treated with dupilumab, with a post-treatment follow-up of at least 16 weeks. The primary endpoints were EASI-75 and the IGA scale at week 52. RESULTS A total of 198 patients were included in the analysis. Mean age was 38 ± 15.1 years and 116 (58.6%) were men. The most prevalent AD-predominant phenotypes were flexural eczema (45.3%), head-and-neck eczema (18.2%) and erythroderma (17.7%). At week 52, 140 (86.4%) patients achieved EASI-75 and 119 (93.0%) achieved an improvement in ≥2 points from baseline in IGA score. Women were 3.6 times more likely to achieve EASI-75 response than men (Odds ratio: 3.58; p = 0.020). While increased body mass index significantly reduced the probability of obtaining an improvement of ≥2 points in the IGA scale at week 52 (odds ratio: 0.88; p = 0.049). CONCLUSIONS Dupilumab was an effective treatment in patients with moderate-to-severe AD. Additionally, sex and body mass index were significantly associated with achieving EASI-75 and an improvement of ≥2 points in the IGA scale, respectively, at week 52.

Abstract
Atopic dermatitis (AD) is a chronic skin condition with intense pruritus, eczema, and dry skin. The recurrent intense pruritus and numerous complications in patients with AD can profoundly affect their quality of life. Obesity is one of its comorbidities that has been confirmed to be the hazard factor of AD and also worsen its severity. Nevertheless, the specific mechanisms that explain the connection between obesity and AD remain incompletely recognized. Recent studies have built hopes on various adipokines to explain this connection. Adipokines, which are disturbed by an obese state, may lead to immune system imbalances in people with AD and promote the development of the disease. This review focuses on the abnormal expression patterns of adipokines in patients with AD and their potential regulatory molecular mechanisms associated with AD. The connection between AD and obesity is elucidated through the involvement of adipokines. This conduces to the in-depth exploration of AD pathogenesis and provides a new perspective to develop therapeutic targets.

Abstract
INTRODUCTION Dupilumab, a biologic approved for treatment of moderate-to-severe atopic dermatitis (AD), has been reported to be largely effective with minimal adverse effects. However, being a targeted therapy, its effectiveness and side effects are expected to be varied in a heterogeneous ethnic population. Currently, the majority of studies on dupilumab are based on Western populations. METHODS A retrospective cohort of 51 patients with moderate-to-severe AD treated with dupilumab at a tertiary skin institute from January 2018 to February 2020 was included. Outcome measures such as Scoring Atopic Dermatitis (SCORAD), Eczema Area and Severity Index (EASI) and Dermatology Quality of Life Index (DLQI) were analysed at baseline and after 16 weeks of treatment. Laboratory tests at the respective time points were also measured. RESULTS Patients treated with dupilumab showed consistent reduction in body surface area (BSA) involved, SCORAD, EASI and DLQI scores. Concurrently, serum immunoglobulin E (IgE) and absolute eosinophil count showed a downward trend at 4 months of treatment. There was a transient increase in mean serum IgE at 1 month of dupilumab treatment. Also, 42.0% and 35.3% of patients developed eye symptoms, and head and neck dermatitis, respectively, but there were no major adverse events reported. Childhood-onset AD was more likely to have improved BSA scores compared to adult-onset AD. CONCLUSIONS Our study confirms the efficacy of dupilumab with real-world data in an adult Asian population. Higher proportions of eye symptoms, and head and neck dermatitis were observed in our cohort compared to other Asian clinical cohort studies. Further studies are needed to evaluate these differences.

Abstract
BACKGROUND Treatment of chronic prurigo (CPG) is challenging. As an antagonist of IL-4R, dupilumab has shown effectiveness in treating CPG in several clinical studies. Recently, the US Food and Drug Administration (FDA) approved dupilumab for the treatment of prurigo nodularis (PN). OBJECTIVES The purpose of this study was to examine the efficacy of dupilumab in Chinese patients with CPG, and to analyze the difference in response between subtypes of CPG. METHODS This retrospective study included 18 patients with CPG who were treated with dupilumab for at least 16 weeks from March 2022 to October 2022. Disease severity and patient self-assessment questionnaires were assessed at baseline and each visit, including the peak Pruritus Visual Analogue Scale (PP-VAS), Prurigo Activity and Severity Score (PAS), Investigator Global Assessment (IGA), Dermatology Life Quality Index (DLQI), Hospital Anxiety and Depression Scale (HADS) and Itchy-specific Quality of Life questionnaire (ItchyQoL). RESULTS After 2 weeks of dupilumab treatment, pruritus scores were significantly reduced as measured by PP-VAS scores. Prurigo Activity and Severity scores decreased significantly at Week 2, whereas IGA improved significantly at Week 8. The DLQI, HADS, and ItchyQoL scores at Week 16 also showed significant improvement from baseline. Patients in all subtypes showed improvement in pruritus and lesion severity. CONCLUSIONS Dupilumab was effective in improving pruritus and lesions in patients with various subtypes of CPG.

Abstract
Recent advances in atopic dermatitis (AD) present the condition as a heterogeneous disease of distinct endotypes across ethnic groups. AD in people with skin of colour may appear psoriasiform, lichenoid, scaly or papular, with a violaceous colour and there is a higher prevalence of post-inflammatory dyspigmentation compared with affected individuals of White ethnicity. These differences in clinical presentation may limit the use of AD assessment tools in people with skin of colour, leading to the potential for misdiagnosis and underestimation of severity, particularly in relation to assessment of erythema. Recent targeted therapies for AD have been studied in multiple ethnic groups; however, ethnicity-based subgroup analysis is often not performed. Further research is required to understand whether treatment responses or safety may differ among ethnic groups.

Abstract
BACKGROUND Few studies have explored transcriptome of the peripheral blood mononuclear cells (PBMCs) of atopic dermatitis (AD). Parameters for prediction of the efficacy of dupilumab in AD remain obscure. OBJECTIVE To explore transcriptome signature of the PBMCs from Chinese AD patients and the usage in predication for the efficacy of dupilumab. METHODS A total of 56 moderate-to-severe adult AD patients were enrolled and followed up for 16 week-dupilumab treatment. PBMCs samples were collected at baseline and 16 weeks after dupilumab treatment. Thirty-five patients were subjected to RNA-sequencing. Weighted gene co-expression network analysis (WGCNA) was used to find genes for prediction of dupilumab efficacy, which was validated in the rest 21 AD patients. Another 30 healthy individuals were enrolled and subjected to RNA-sequencing as healthy controls. RESULTS Upregulation of the T helper (Th) 2/Th22 pathway, Th17 antimicrobial genes, and natural T-regulatory cell abundance in the PBMCs of AD cases was observed, whereas TGF-β signaling and NK-cell signaling were decreased. Dupilumab treatment reversed the increase in the expression of Th2 cytokine receptors. WGCNA identified two immune-related modules that were correlated significantly with the efficacy of dupilumab. Hub gene MAP2K3 and UBE2L3 of these two modules demonstrated potential predictive ability for efficacy in the RNA-sequencing group by Spearman correlation, ROC analysis, and regression analysis, which was further validated in additional 21 AD cases. CONCLUSION We firstly revealed the molecular phenotype of PBMCs in Chinese patients with AD, and uncovered two molecules that might be useful for prediction of the efficacy of dupilumab.

Abstract
Atopic dermatitis (AD) is now a global health problem and has been attracting extensive attention from both academic and public society in China. This review aimed to present the current status of the prevalence, disease burden, clinical features, diagnosis, and management of AD in China. The prevalence of AD has been increasing rapidly in China during the past decades, partially due to the increased recognition of the disease; there are still substantial amounts of over-diagnosed eczema and under-diagnosed AD. Chinese dermatologists see many AD patients with atypical manifestation, which poses a challenge to the diagnosis. The Chinese diagnostic criteria for adults and pediatric patients with AD have been proposed respectively and validated with high sensitivity and specificity. International and Chinese guidelines for management of AD have been popularized; however, there are still many practices that need verification through randomized case-control study. Dupilumab and JAK inhibitors have demonstrated favorable efficacy for AD patients in China, and a multidimensional approach is needed for selection of the patients and evaluation of the efficacy and safety. Patient education and long-term management for AD are just beginning in China, and need to be strengthened in the future.

Front Immunol 2023; 14:1160710. [PMID: 37153599 PMCID: PMC10157040 DOI: 10.3389/fimmu.2023.1160710] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Accepted: 04/05/2023] [Indexed: 05/09/2023] Open
Abstract
Background The real-world experience of dupilumab in Chinese is limited, and the initial loading dose has not yet been deeply explored in patients aged <6 years. Objective To explore the efficacy and safety of dupilumab in Chinese patients with moderate-to-severe atopic dermatitis and investigate the effect of higher loading dose for disease control in patients aged <6 years. Methods A total of 155 patients were divided into three groups according to age: <6 years, 6-11 years, and >11 years. Among patients aged <6 years, 37 patients received a high loading dose of 300 mg for body weight <15kg or 600 mg for body weight ≥15kg, and another 37 patients received a standard loading dose of 200 mg for body weight <15kg or 300 mg for body weight ≥15kg. Multiple physicians and patient-reported outcome measures were evaluated at baseline and 2, 4, 6, 8, 12, and 16 weeks after dupilumab treatment. Results The proportion of patients showing an improvement of ≥75% in the Eczema Area and Severity Index was 68.0% (17/25), 76.9% (10/13), and 62.5% (25/40) in the aged <6, 6-11, and >11 years groups, respectively, at week 16. After increasing the loading dose, 69.6% (16/23) of patients aged <6 years achieved 4-point improvement in Pruritus Numerical Rating Scale at week 2, compared with 23.5% (8/34) of patients receiving standard loading dose (P < 0.001). Obesity (odds ratio=0.12, 95% confidence interval: 0.02-0.70) was predictive of a poor response to dupilumab treatment, while female (odds ratio=3.94, 95% confidence interval: 1.26-12.31) predicted good response at week 16. The change of serum C-C motif ligand 17(CCL17/TARC) could reflect the response to dupilumab (r = 0.53, P = 0.002 in EASI) among patients aged <18 years. No major adverse events were reported during the treatment. Conclusions Dupilumab was effective and well-tolerated in Chinese patients with atopic dermatitis. The increased loading dose helped achieve rapid pruritus control in patients aged <6 years.

Front Immunol 2022; 13:1054422. [PMID: 36569942 PMCID: PMC9773867 DOI: 10.3389/fimmu.2022.1054422] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Accepted: 11/23/2022] [Indexed: 12/14/2022] Open
Abstract
Background Netherton syndrome is a rare, life-threatening autosomal recessive genetic disorder with no effective treatment yet. Skin barrier dysfunction caused by SPINK5 gene mutations is a hallmark of the disease. Antigen penetration through the defective skin and nonspecific inflammation provide a pro-T helper 2 (Th2) immune microenvironment in the disease. Therefore, Th2 cytokines are considered to be candidate therapeutic targets. Objective To evaluate the clinical responses of patients with Netherton syndrome to dupilumab, an IL-4Rα antagonist, and identify changes in the Th1/2/17 pathway activity, skin barrier defect protein LEKTI expression after treatment. Methods Four children with severe Netherton syndrome (aged 2 y to 4 y and 6 m) who were treated with dupilumab from January to June 2022 were evaluated at baseline, and at 4, 8, 12, 16, and 20 weeks after the start of dupilumab administration. Treatment response was assessed using the Eczema Area and Severity Index (EASI), the Numerical Rating Scale (NRS), the Dermatology Life Quality Index (CDLQI), and the Dermatitis Family Impact-questionnaire (DFI). Blood eosinophil counts, serum IgE levels and inflammatory cytokines were measured. The immunotyping of Th1/2/17 cells was performed by flow cytometry and cytokine expressions in T cell subsets were analyzed by single-cell RNA sequencing. In addition, expression of the LEKTI in skin lesions was evaluated by immunohistochemical analysis. Results All four patients experienced clinical improvement, with significantly reduced EASI scores (by 75.0-83.9%) and NRS (by 87.5-90.0%) from baseline to 20 weeks of treatment. Improved quality of life scores were also seen for all patients, as measured by CDLQI and DFI. Serum IgE levels also fell by 75.6-86.9%. The serum Th2 cytokines IL-4, IL-5 and IL-13 were found at low level, with no significant changes during the treatment. However, Th2 cytokines expressed by T cells, especially IL-4, decreased at single-cell level after treatment (P = 0.029). The baseline percentage of Th2 cells (among total CD3+CD4+ T cells) was significantly higher in patients than that in healthy controls (HC) (P < 0.0001); this percentage fell from 8.25% ± 0.75% to 4.02% ± 0.62% after 20 weeks dupilumab treatment. There was no noticeable change in LEKTI protein expression in skin lesions pre- and post-treatment. Two patients reported mild ocular adverse effects, but there were no severe adverse events. Conclusion Dupilumab may be an effective and safe treatment option in a subset of pediatric patients with Netherton syndrome, especially in improving itch and the quality of life. These effects were achieved in part by suppression of the Th2-mediated inflammation.
