RESUMEN
CLINICAL IMPLICATIONS: Dupilumab, a biological therapy that blocks the shared receptor component for interleukins-4/13, reduced exacerbations and improved lung function in children with uncontrolled moderate-to-severe type 2 asthma independent of most baseline patient and asthma characteristics.
RESUMEN
BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a prevalent chronic inflammatory condition affecting the nose and paranasal sinuses, posing a significant socio-economic impact with substantial challenges in management. Biologics targeting type 2 inflammation such as dupilumab, have emerged as promising options. This study addresses a critical knowledge gap by comprehensively evaluating the 3-year impact of sustained dupilumab therapy in CRSwNP. METHODS: A multicentric, retrospective collection of real-world data from five tertiary referral centers in Germany was conducted, enrolling 150 adult patients. The study investigated patient-reported outcomes, disease-specific indices and clinical measures, focusing on therapeutic response persistence, adverse events, and factors influencing treatment continuity. RESULTS: Results indicate significant improvements in clinical parameters from baseline (n = 150) with sustained effectiveness after 36 months (n = 138) as indicated in mean score ± standard deviation. Dupilumab treatment significantly improved overall disease-related impairment (VAS score: 7.5 ± 2.5 to 1.6 ± 1.3) and rhinosinusitis symptoms (SNOT-22: 59.4 ± 19.4 to 18.0 ± 15.0). Nasal Polyp Scores (NPS) decreased (5.3 ± 1.8 to 0.7 ± 1.1), and olfactory function improved (3.2 ± 2.5 to 8.4 ± 2.8), with three out of four patients achieving normosmia or hyposmia after 36 months. An "Excellent" treatment response according to EUFOREA23 criteria was observed in 76.5% of patients after 36 months. Sixteen patients discontinued Dupilumab, 12 permanently. Adverse events totaled 69 in 48 patients, commonly self-limiting. CONCLUSION: The study highlights the enduring effectiveness and lack of habituation to dupilumab after a sustained therapy of 3 years, providing valuable insights into its long-term therapeutic implications for CRSwNP patients.

BACKGROUND: The indications for endoscopic modified Lothrop procedure (Draf 3) in patients with refractory chronic rhinosinusitis with nasal polyposis (CRSwNP) remain unclear. This study evaluates the effectiveness of Draf 3 for refractory CRSwNP focusing on improvements in disease severity and need for subsequent dupilumab rescue therapy. METHODS: Retrospective review of patients with CRSwNP undergoing Draf 3 surgery at a tertiary center between 2012 and 2022. Clinicodemographic variables were compared across those who did versus did not require rescue with postoperative dupilumab. Time to postoperative dupilumab rescue was analyzed and longitudinal disease-specific outcomes were measured using the sinonasal outcomes test (SNOT-22). RESULTS: Within 87 patients with CRSwNP, 24.1% had aspirin-exacerbated respiratory disease (AERD). Significant improvement in SNOT-22 score was found in CRSwNP with AERD (p < 0.001) and without AERD (p = 0.01) up to 24 months postoperative. 14.9% eventually required rescue with a dupilumab. More specifically, of 21 patients with AERD, 24.1% eventually required rescue with dupilumab. Dupilumab rescue was associated with a greater number of prior sinus surgeries (p = 0.02), prior aspirin desensitization (p = 0.02), and worse preoperative Lund-MacKay scores (p < 0.001). No association between biologic rescue and frontal recess antero-posterior diameter was found (p = 0.20). CONCLUSIONS: Draf 3 surgery in CRSwNP was associated with significant improvement in SNOT-22 score at 24 months. Furthermore, only 14.9% of patients required dupilumab rescue. Patients with AERD were more likely to require rescue with dupilumab even though 75.1% avoided treatment with the biologic over the study period.
RESUMEN
INTRODUCTION: Atopic dermatitis (AD), with its hallmark symptoms of pruritus and skin lesions, often impairs patients' quality of life. We assessed time spent with clear/almost clear skin and no/minimal itch during upadacitinib treatment versus placebo or dupilumab among patients with moderate-to-severe AD. METHODS: This analysis consisted of a post hoc analysis of Measure Up 1 (NCT03569293), Measure Up 2 (NCT03607422), and Heads Up (NCT03738397). Measure Up 1 and 2 were replicate, randomized, double-blind, placebo-controlled phase 3 studies with patients randomized (1:1:1) to once-daily oral upadacitinib 15 mg, upadacitinib 30 mg, or placebo for 16 weeks. Heads Up was a head-to-head, randomized, double-blind, double-dummy, phase 3b study with patients randomized (1:1) to upadacitinib 30 mg or subcutaneous dupilumab 300 mg for 24 weeks. Skin clearance was assessed with the Eczema Area and Severity Index (EASI) at baseline, weeks 1, 2, and 4, and every 4 weeks thereafter. Itch was assessed using the Worst Pruritus Numerical Rating Scale (WP-NRS) daily over 16 weeks and every 2 weeks thereafter to week 24 in Heads Up. RESULTS: This analysis included 1683 patients in Measure Up 1 and 2 and 673 patients in Heads Up. Through 16 weeks in Measure Up 1 and 2, patients receiving upadacitinib spent 9.8-13.4 times as many days with an EASI 90 response and 7.0-10.3 times as many days with a WP-NRS 0/1 response versus placebo. In Heads Up, patients receiving upadacitinib spent 2.0 and 1.7 times as many days through 16 and 24 weeks, respectively, with an EASI 90 response versus dupilumab. Through 16 and 24 weeks, patients receiving upadacitinib spent 3.0 and 2.6 times as many days, respectively, with a WP-NRS 0/1 response versus dupilumab. CONCLUSIONS: Patients with moderate-to-severe AD spent more time with clear/almost clear skin and no/minimal itch with upadacitinib versus placebo or dupilumab.

BACKGROUND: Systemic Janus kinase inhibitors (JAKi) and dupilumab both have emerged as promising therapeutics for atopic dermatitis (AD). While dupilumab has a favorable safety profile, use of oral JAKi has been established in other diseases that carry potential comorbid susceptibilities that influence safety. OBJECTIVE: To provide real-world evidence of the safety of oral JAKi in AD patients. METHODS: The study used observational data from TriNetX (Cambridge, Massachusetts). Patients with AD treated with either oral JAKi (upadacitinib, abrocitinib, and baricitinib) or dupilumab were enrolled. The two treatment groups were propensity-score matched 1:1 based on demographics, comorbidities, and prior medications. Safety outcomes within two years after the initiation of medications were measured by hazard ratios with 95% confidence intervals. RESULTS: A total of 14,716 patients were included, with 942 patients treated with oral JAKi and 13,774 with dupilumab. The two treatment groups included 938 patients after matching. Treatment with oral JAKi was not associated with increased risks of mortality, malignancies, major adverse cardiovascular events, venous thromboembolism, renal events, or serious gastrointestinal events. However, patients receiving oral JAKi showed significantly higher risks of skin and subcutaneous tissue infection, herpes infection, acne, cytopenia, and hyperlipidemia, whereas the risk of ophthalmic complications was higher in those receiving dupilumab. CONCLUSION: This study found that oral JAKi did not exhibit concerning safety issues in treating patients with AD but increased the risk of infections and laboratory abnormalities. Long-term follow-up data are required to validate these findings.
RESUMEN
Background: Dupilumab is a monoclonal antibody used for the treatment of moderate/severe atopic dermatitis (AD). In recent years, several studies have confirmed the positive association between AD and overweight/obesity, and a report demonstrated the effect of weight reduction on the improvement of AD symptoms. Methods: The weight of 170 patients under treatment with dupilumab was recorded at baseline and after 48 weeks (T48). Clinical monitoring was mainly conducted using the Eczema Area and Severity Index (EASI). The study aimed to assess a possible correlation between the clinical outcome of dupilumab therapy and BMI. Results: Although not statistically significant, patients with a BMI < 25 have a higher EASI percentage improvement than patients with a BMI ≥ 25 at any time point, and the percentage of overweight and obese patients that does not reach EASI-75 at T48 is higher compared to normal-weight patients (13.5% vs. 5.9%). Despite this, in the multivariate regression analysis, no baseline characteristic, including BMI, appears to increase the risk of not reaching EASI-75. In addition, the results show no differences in BMI between baseline and T48 in any age/sex group. Conclusions: The results suggest that overweight and obese patients have a lower response to dupilumab when considering the EASI score, but this difference does not appear to be clinically significant. Furthermore, dupilumab treatment does not seem to impact weight.
RESUMEN
Lichen sclerosus et atrophicus (LSA) is a chronic inflammatory skin lesion with an undefined cause. It is more commonly found in the genital area, particularly in adolescents, premenopausal women and postmenopausal women. LSA is difficult to treat and often recurs. The primary treatment for LSA involves the administration of potent topical corticosteroids. Dupilumab is increasingly being used for the treatment of itching in non-atopic dermatitis patients but there are few reports on its use for the treatment of LSA. Here, we present a case of LSA in a 61-year-old woman with extensive vulvar itching. Over four months of dupilumab therapy, significant therapeutic effects were observed, including vulvar skin thinning and pruritus relief without adverse reactions.
RESUMEN
Pulmonary manifestations in patients with allergic bronchopulmonary aspergillosis (ABPA) and nontuberculous mycobacterial-pulmonary disease (NTM-PD) include bronchiectasis and mucus plugging. A 68-year-old woman, treated with antibiotics and inhaled corticosteroids for NTM-PD and asthma, presented with fever and wheezing. ABPA was diagnosed based on laboratory findings (elevated peripheral blood eosinophil counts and serum total IgE levels and positive Aspergillus-specific IgE and IgG) and imaging observation of a high-attenuation mucus plug. Systemic prednisolone was avoided to prevent NTM-PD progression. Dupilumab, a monoclonal antibody that blocks IL-4/13, was introduced to improve the clinical findings. Herein, we discuss the pathophysiological mechanisms underlying this rare comorbidity.
RESUMEN
KEY POINTS: A persistent type 2 endotype signature exists in recalcitrant chronic rhinosinusitis with nasal polyps mucosa on dupilumab. Revision sinus surgery immediately prior to dupilumab reduces long-term interleukin (IL)-4/IL-13 tissue mRNA. Pre-dupilumab revision surgery is associated with reduced tissue eosinophils and GATA-3+ cells.
RESUMEN
The definition of paradoxical psoriasis (PP) encompasses 2 main scenarios, namely, (i) new-onset psoriasis in patients treated for a different disease and (ii) worsening as well as phenotypical change of pre-existing psoriasis. Originally restricted to the appearance of an untoward psoriasiform reaction under TNF inhibitors, the term has gained new meaning, with the progressive observation of psoriasis-like eruptions also with other medications. Although the conceptual framework of PP has expanded, a molecular and clinicotherapeutic classification is still lacking. In addition, a certain degree of confusion surrounds the correct terminology to indicate these eruptions. In this paper, evidence on the epidemiology, clinical features, pathogenesis, and treatment of PP is reviewed, providing a perspective on possible pathogenesis-driven therapeutic approaches.
RESUMEN
Our study aims to synthesize existing evidence of dupilumab for alopecia areata (AA) in pediatric patients with atopic dermatitis (AD). We searched MEDLINE and Embase on March 1, 2024, using keywords related to AD, AA, dupilumab, and pediatric patient populations per PRISMA-ScR guidelines. A mean SALT score reduction of 42.6 following dupilumab treatment (p < .01) over an average of 3.21 months, and a mean reduction of Investigator Global Assessment (IGA) levels of 2.14 units (p < .01) demonstrates the efficacy of dupilumab in pediatric AA when there is concurrent AD. Our findings in combination with dupilumab's favorable safety profile in pediatric AD makes it an appealing option for AA treatment, however, a greater understanding of the underlying mechanisms, optimal pediatric patient selection criteria, long-term efficacy, and safety profile of dupilumab in this context is warranted.
RESUMEN
This report presents two cases of patients with long-standing, treatment-resistant Hailey-Hailey disease (HHD) who experienced significant symptom relief through a combination therapy of oral naltrexone and dupilumab injections. The therapeutic potential of targeting the Th2 pathway and Ca2+ signaling with dupilumab in managing HHD manifestations is highlighted. The findings suggest that Th2 blockade with dupilumab, in conjunction with naltrexone, effectively controls recalcitrant HHD, indicating a role of cytokine response in altering disease pathogenesis. This case contributes to the growing body of literature on biologic treatments for HHD and suggests avenues for further research in HHD management.
RESUMEN
BACKGROUND: A preference for type 2 immunity plays a central role in the pathogenesis of atopic dermatitis (AD). Dupilumab, a monoclonal antibody targeting the IL-4α receptor 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-4RA+ memory B-cells (MBC2) 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: To assess the effects of dupilumab treatment in comparison to alternative therapies on the frequency of MBC2 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 three treatment groups: dupilumab (n=12), cyclosporine (n=12), or topical treatment (n=12). Plasma and Peripheral Blood Mononuclear Cells (PBMCs) were collected at baseline (T0) and after 6 months (T6). Flow cytometry was employed for PBMC phenotyping, ELISA was utilized to assess total IgE levels in plasma. For detailed Methods, please see the Methods section in this article's Online Repository at www.jacionline.org RESULTS: Our findings revealed a significant reduction in MBC2 frequency and total IgE levels among patients treated with dupilumab. Additionally, a significant correlation was observed between MBC2s and total IgE levels CONCLUSION: Systemic blocking of the IL-4RA subunit leads to a decrease in circulating MBC2 cells and total IgE in pediatric AD patients. Our findings unveil a novel mechanism through which dupilumab exerts its influence on the atopic signature.
