Background Dupilumab is licensed for the treatment of moderate-to-severe atopic dermatitis (AD) in patients aged ≥ 6 months. Objectives The aim of this study was to examine real-world outcomes and safety of dupilumab in British children with moderate-to-severe AD attending a tertiary referral paediatric centre. Methods Skin and quality of life scores, adverse events and discontinuation rates were assessed. Patients aged ≤ 18 years with moderate-to-severe AD were included if they had skin scores recorded at baseline and at least one follow-up visit. Efficacy and safety were assessed using descriptive statistics. Results In this retrospective observational survey, 72 children/teenagers, with a median age of 14 years (range 7–18) were included. Oral systemic immunosuppressants had failed to control AD in 88% of children recruited. All patients commenced on dupilumab had pretreatment eczema skin scores consistent with moderate-to-severe disease, with a median Eczema Area and Severity Index (EASI) score of 25 [interquartile range (IQR) 20–31]. EASI scores decreased by a median of 94% (IQR 82–100) and remained consistently low over 10–52 months of the study, with a median EASI score at final follow-up of 2 (IQR 0–6). Of the 72 children, 8 (11%) were able to discontinue dupilumab as they were in remission. Nineteen (26%) experienced adverse events, most commonly conjunctivitis (12 patients; 17%). Eight (11%) discontinued dupilumab (six with ongoing inflammatory skin flares, one with severe allergic conjunctivitis, one with intercurrent Wilson disease). Conclusions Dupilumab was highly effective in treating most children with moderate-to-severe AD with good safety outcomes in the real world. However, 10% of children may need alternative therapy because of drug ineffectiveness or side-effects. [ABSTRACT FROM AUTHOR]

Background: Atopic dermatitis (AD) is frequently associated with asthma and allergic rhinitis (AR). Dupilumab is an effective treatment for pediatric AD, although the effect on atopic comorbidities in pediatric AD patients is limited. Objective: To investigate the prevalence of asthma and AR in pediatric AD patients starting dupilumab treatment and to evaluate the effect of dupilumab on these comorbidities. Methods: This study included pediatric AD patients (aged 3–17 years) treated with dupilumab between 2019 and 2023. Patients were screened at baseline by a pulmonologist for the presence of asthma and AR. Screening included evaluation of medical history and current symptoms, spirometry (including Forced Expiratory Volume in 1 s (FEV1)), Fractional exhaled Nitric Oxide (FeNO), and measurement of aeroallergen‐specific IgE levels. In patients diagnosed with comorbid asthma and/or AR, measurements were repeated at weeks 16 and 52. Spirometry measurements, FeNO, and aeroallergen‐specific IgE levels during treatment were analyzed using a covariance pattern model. Results: Eighty‐four patients were included. Asthma was diagnosed in 50 patients (59.5%) and AR in 72 patients (85.7%). Baseline FeNO levels were elevated in both patients with (29.0 ppb (95% CI 22.0–54.0)) and without asthma (26.0 ppb (95% CI 22.0–30.0)). During treatment, FeNO levels decreased (p <.001) and FEV1 scores increased (p <.001) in patients with asthma. In patients with asthma and/or AR, all aeroallergen‐specific IgE levels decreased between 61.3% and 89.1% at 52 weeks of treatment. Conclusion: One year of dupilumab treatment, primarily indicated for AD, resulted in a significant improvement in comorbid asthma and a profound decrease in aeroallergen‐specific IgE levels in patients with asthma and/or AR.

Atopic dermatitis (AD) is still a demanding challenge in clinical practice. Type 2 inflammation is the most common inflammatory pathway in children and adolescents with AD. Anti‐inflammatory drugs, mainly corticosteroids (CS) and immunomodulant agents are the primary therapeutic approach to dampening type 2 inflammation. However, AD patients may require long‐term high CS doses or drug combinations with possibly significant adverse effects to achieve and maintain disease control. In this regard, the advent of biologics constituted a breakthrough in managing this condition. Dupilumab is a monoclonal antibody directed against the IL‐4 receptor α‐subunit (IL‐4Rα), antagonizing both IL‐4 and IL‐13 and is approved for pediatric severe AD. This review presents and discusses the most recent published studies on dupilumab in children and adolescents with AD. There is convincing evidence that dupilumab is safe and effective in managing AD. It can reduce skin lesions and associated itching, reduce the need for additional medications, and improve disease control and quality of life. However, a thorough diagnostic pathway is mandatory, especially considering the different AD phenotypes. The ideal eligible candidate is a child or adolescent with AD requiring systemic treatment because of severe clinical manifestations and impaired quality of life. [ABSTRACT FROM AUTHOR]

Purpose: Nowadays, several efficacious biologic drugs are used for severe asthma with or without chronic rhinosinusitis with nasal polyps (CRSwNP). However, it has been observed that not all comorbid patients (asthma/CRSwNP) receiving biologic treatment for asthma experience satisfactory control of both conditions equally. Methods: We selected 20 patients who had both severe asthma and comorbid CRSwNP under biological treatment with benralizumab, omalizumab or mepolizumab with adequate control of asthma but inadequate control of nasal symptoms. Patients were switched to dupilumab and outcomes were evaluated at baseline (T0), at 3 months (T1), at 6 months (T2), at 12 months (T3) and finally at 18 months (T4). Data were collected at each time point including blood tests measuring eosinophil levels and total IgE, SNOT22, ACT, NPS score, rhinomanometry, olfactory testing, and nasal cytology. Results: The results showed an overall improvement in all the outcomes. Peripheral eosinophilia was observed consistently with existing literature. All patients registered an improvement in sinonasal outcomes, while only one patient had a worsening of asthma. Three patients interrupted the therapy due to various causes: poor asthma control, onset of psoriasis and thrombocytopenia. Conclusions: The response to a biologic treatment for CRSwNP control may be heterogenous and it seems that patients may benefit from switching improving control in equal measure in the upper and lower airway. Further studies to explore the endotype/phenotype which best fits with each biologic are mandatory to personalize the therapy. [ABSTRACT FROM AUTHOR]

L'échinococcose alvéolaire est une parasitose endémique sévissant dans certaines zones froides de l'hémisphère Nord incluant notamment l'Est de la France, la Suisse, l'Allemagne, le Canada ou les États-Unis. Largement sous-diagnostiquée, elle est liée à l'infection par Echinococcus multilocularis , un petit taenia appartenant à la classe des cestodes, pouvant entraîner une atteinte multisystémique notamment chez le patient âgé ou immunodéprimé. Nous rapportons le cas d'une patiente de 82 ans, immunodéprimée par une corticothérapie prolongée et un traitement par dupilumab. Elle était adressée dans notre service pour bilan diagnostique de lésions hépatiques et pulmonaires atypiques, initialement suspectes de tuberculose ou de maladie associée aux IgG4. L'hypothèse d'une échinococcose alvéolaire à E. multilocularis a pu être évoquée sur un faisceau d'arguments, puis confirmée par diagnostic moléculaire. Nous évoquons et discutons le rôle du dupilumab dans l'évolution systémique et la présentation atypique de la maladie, par l'induction d'une immunodépression spécifique. L'échinococcose alvéolaire devrait être systématiquement recherchée en cas de maladie systémique comprenant une atteinte hépatique et pulmonaire au premier plan, surtout chez le sujet immunodéprimé. Alveolar echinococcosis is an endemic parasitic disease prevalent in certain cold regions of the Northern Hemisphere, including Eastern France, Switzerland, Germany, Canada, and the United States. Widely underdiagnosed, it is associated with infection by Echinococcus multilocularis , a small tapeworm belonging to the cestode class, capable of causing multi-systemic involvement, particularly in elderly or immunocompromised patients. We present the case of an 82-year-old patient, immunocompromised due to prolonged corticosteroid therapy and treatment with dupilumab. She was referred to our department for a diagnostic assessment of atypical hepatic and pulmonary lesions, initially suspected of tuberculosis or an IgG4-related disease. The hypothesis of alveolar echinococcosis caused by E. multilocularis was eventually considered based on a set of arguments, further confirmed by molecular diagnosis. We discuss the role of dupilumab in the systemic evolution and atypical presentation of the disease, through the induction of a specific immunosuppression. Alveolar echinococcosis should be systematically considered in case of systemic disease with prominent hepatic and pulmonary involvement, especially in immunocompromised patients.

The French National Society of Gastroenterology was at the initiative of drafting recommendations for the diagnosis and management of eosinophilic esophagitis in adults. A working group has drawn up 30 recommendations based on the most up-to-date data from the international scientific literature on the following themes: diagnosis, therapeutic objectives, initial treatment, esophageal dilation, maintenance treatment. For each recommendation, the GRADE methodology made it possible to determine the level of evidence (high, moderate, low, very low) and a strong or conditional level of recommendation. After two rounds of voting all the recommendations proposed reached an agreement of more than 80 % of voters. [ABSTRACT FROM AUTHOR]

Objectives: This post hoc analysis assessed disease characteristics and response to dupilumab treatment in male and female patients with severe chronic rhinosinusitis with nasal polyps (CRSwNP) (SINUS‐52 study; NCT02898454). Methods: Patients received dupilumab 300 mg or placebo every 2 weeks for 52 weeks on background intranasal corticosteroids. Efficacy was assessed through Week 52 using nasal polyp score (NPS), nasal congestion/obstruction score, loss of smell score and University of Pennsylvania Smell Identification Test score. Disease‐specific health‐related quality of life (HRQoL) was assessed using the 22‐item Sino‐Nasal Outcome Test (SNOT‐22). Results: The analysis included 192 male and 111 female patients. Female patients had higher mean SNOT‐22 total score (56.6 vs. 49.1, P < 0.01) and more coexisting asthma (78.4% vs. 46.4%, P < 0.0001) and non‐steroidal anti‐inflammatory drug‐exacerbated respiratory disease (NSAID‐ERD) (38.7% vs. 18.8%, P = 0.0001) than male patients, but other baseline characteristics were similar. Dupilumab significantly improved CRSwNP outcomes vs. placebo at Week 52, regardless of gender: least squares mean differences (95% confidence interval) for NPS were −2.33 (−2.80, −1.86) in male and −2.54 (−3.18, −1.90) in female patients (both P < 0.0001 vs. placebo), and for SNOT‐22 were −19.2 (−24.1, −14.2) in male and −24.4 (−31.5, −17.3) in female patients (both P < 0.0001 vs. placebo). There were no significant efficacy‐by‐gender interactions. Conclusion: Female patients had greater asthma, NSAID‐ERD and HRQoL burden at baseline than male patients. Dupilumab treatment significantly improved objective and subjective outcomes compared with placebo, irrespective of gender. [ABSTRACT FROM AUTHOR]

Several reports have described dupilumab‐induced eosinophilic pneumonia (EP) after treatment with dupilumab in patients with type 2 inflammatory disease. Other reports have suggested the efficacy of dupilumab for chronic EP (CEP). Whether dupilumab can be continued in patients with type 2 inflammatory disease who develop EP during dupilumab treatment remains unclear. We present herein three cases with different clinical presentations involving dupilumab and EP. In Case 1, dupilumab was discontinued because of dupilumab‐induced EP during the treatment of asthma. In Case 2, although pre‐existing idiopathic EP worsened during the treatment of eosinophilic chronic rhinosinusitis (ECRS), dupilumab was continued. In Case 3, CEP and ECRS were successfully treated with dupilumab and corticosteroids were discontinued. In conclusion, treatment with dupilumab in patients with type 2 inflammatory disease and idiopathic EP is worth considering if the benefits are deemed to outweigh the risks and careful attention is given to the clinical course.

Despite high disease burden, systemic treatment options for patients with atopic hand and/or foot dermatitis (H/F AD) are limited. To evaluate efficacy and safety of dupilumab in H/F AD using specific instruments for assessing disease severity on hands and feet. In this multicenter phase 3 trial, adults and adolescents with moderate-to-severe H/F AD were randomized to dupilumab monotherapy (regimen approved for generalized AD), or matched placebo. The primary endpoint was proportion of patients achieving Hand and Foot Investigator's Global Assessment score 0 or 1 at week 16. Secondary prespecified endpoints assessed the severity and extent of signs, symptom intensity (itch, pain), quality of life, and sleep. A total of 133 patients (adults = 106, adolescents = 27) were randomized to dupilumab (n = 67) or placebo (n = 66). At week 16, significantly more patients receiving dupilumab (n = 27) than placebo (n = 11) achieved Hand and Foot Investigator's Global Assessment score 0 or 1 (40.3% vs 16.7%; P =.003). All other prespecified endpoints were met. Safety was consistent with the known AD dupilumab profile. Short-term, 16-week treatment period. Dupilumab monotherapy resulted in significant improvements across different domains of H/F AD with acceptable safety, supporting dupilumab as a systemic treatment approach for this often difficult to treat condition.

We report the case of a 55-year-old female with eosinophilic granulomatosis with polyangiitis and chronic rhinosinusitis with nasal polyp. Rhinosinusitis recurred 6 months after full-house endoscopic sinus surgery. Although conventional treatment with azathioprine and mepolizumab with steroids was given, it was difficult to simultaneously control both rhinosinusitis and eosinophilic granulomatosis with polyangiitis. Clinical examinations showed polyps in the olfactory cleft, and the patient's anosmia gradually became persistent. Even after administering mepolizumab for a certain period of time, symptoms did not improve, but when the biologic agent was switched to dupilumab, an improvement in recalcitrant chronic rhinosinusitis with nasal polyp was observed. While dupilumab was administered intermittently for refractory chronic rhinosinusitis with nasal polyp, the rhinosinusitis improved and symptoms such as worsening of eosinophilic granulomatosis with polyangiitis paresthesia were observed. Both symptoms gradually subsided 19 months after starting intermittent administration, leading to the discontinuation of dupilumab administration. Rhinosinusitis in the setting of eosinophilic granulomatosis with polyangiitis may be refractory in some cases, and this case provides findings demonstrating the strong effect of dupilumab on eosinophilic inflammation.

Rationale: The comparative effectiveness of biologic agents used as add-on therapy in the management of difficult-to-control asthma is unclear. Objective: To compare the effectiveness of dupilumab, mepolizumab, and benralizumab among patients with difficult-to-control asthma. Methods: Retrospective multicenter cohort study of adult patients with difficult-to-control asthma starting treatment with dupilumab, mepolizumab, or benralizumab as documented in a multicenter electronic health record and claims-based database between October 19, 2018, and September 30, 2022. Propensity-score matching was used to minimize bias from nonrandomized treatment assignment; a prespecified α-level was set at 0.017 to account for three primary comparisons. The exposure of interest was the new initiation of dupilumab, benralizumab, or mepolizumab treatment. The primary outcome was the rate of asthma exacerbations in the 1 year after initiation of biologic therapy modeled using a negative binomial approach. Results: Among 893,668 patients with asthma who were prescribed an inhaled corticosteroid and were ⩾12 years old (65% female; mean age, 49 yr), 3,943 started dupilumab, 1,902 started benralizumab, and 2,012 started mepolizumab, all without an alternative indication for biologic therapy. After matching, there were 1,805 patients in each group for comparisons between dupilumab and benralizumab, 1,865 for comparisons between dupilumab and mepolizumab, and 1,721 for comparisons between mepolizumab and benralizumab. For all pairwise comparisons, covariates were well balanced after matching (all standardized mean differences <0.1). Patients who initiated dupilumab had a significantly lower rate of asthma exacerbations (1.07 per year) compared with benralizumab (1.47 per year), with a rate ratio (RR) of 0.73 (95% confidence interval, 0.63–0.85), and also had a significantly lower rate of asthma exacerbations compared with mepolizumab (1.04 per year vs. 1.45 per year), with an RR of 0.72 (0.62–0.84). There was no statistically significant difference in the rate of asthma exacerbations between mepolizumab (1.40 per year) and benralizumab (1.41 per year), with an RR of 1.00 (0.85–1.17). Conclusions: In patients with difficult-to-control asthma who had newly initiated biologic therapy, dupilumab was associated with a decreased rate of asthma exacerbations in the 1 year after initiation compared with mepolizumab or benralizumab.

Objective: To provide real‐life evidence on long‐term radiological changes in patients with severe chronic rhinosinusitis with nasal polyps (CRSwNP) treated with dupilumab, and to assess possible differences between radiological and clinical results in terms of endoscopic findings and Patient‐Reported‐Outcomes (PROs). Methods: Consecutive patients treated with dupilumab for recalcitrant CRSwNP were required to undergo CT scan at baseline (T0) and after 12 (T1) since first administration. A group of patients also performed CT scan at 52 weeks (T2) to assess long‐term outcomes. At each timepoint, patients underwent nasal endoscopy, assessment of Nasal‐Polyp‐Score (NPS), Lund‐Kennedy‐Score (LKS), and had to fill in the 22‐item Sinonasal‐Outcome‐Test (SNOT‐22) and Visual‐Analogue‐Scales (VAS) for sinonasal symptoms. Results: In fifty‐three included patients, from T0 to T1 we detected a significant reduction in mean Lund‐Mackay score (LM), PROs (SNOT‐22, VAS) and endoscopic (NPS, LKS) scores (p < 0.05). In the subset of patients that reached T2 (n = 30), compared to T1, we observed a further significant decrease in mean LM, SNOT‐22, VAS, and NPS scores, but not in LKS (p = 0.420). At T1, the highest improvement was observed in PROs (SNOT‐22: 56.26%), and polyp size (NPS: 49.83%). Conversely, between T1 and T2, sinus opacification was shown to be the most improved outcome (LM: 36.86%). Conclusions: Our experience showed that poorly controlled CRSwNP patients treated with dupilumab experienced significant improvement in radiologic, endoscopic and clinical disease severity. While in the initial 3 months, PROs garnered attention for showing earlier effectiveness, radiological outcomes revealed sustained and gradual efficacy in a longer term. Level of Evidence: Level 4. According to the Oxford Center for Evidence‐Based Medicine 2011 level of evidence guidelines, this non‐randomized retrospective cohort study is classified as level 4 evidence Laryngoscope, 134:2626–2633, 2024 [ABSTRACT FROM AUTHOR]

Objectives: Ocular surface reactions (OSR) have been associated with dupilumab for atopic dermatitis (AD) treatment. However, the association of dupilumab‐associated OSR (DA‐OSR) for nasal polyps (CRSwNP) treatment has not been studied. We evaluated DA‐OSR for CRSwNP treatment using the FDA Adverse Event Reporting System (FAERS). Methods: FAERS was queried for any general ocular reactions (DA‐GOR) from 2019Q1 to 2022Q4. DA‐OSR were subcategorized from DA‐GOR and compared between treatment groups (CRSwNP, asthma, AD). Logistic regression was used to predict DA‐OSR. Disproportionality analysis (DPA) of DA‐OSR was performed using OpenVigil. Results: There were 60,198 total observations, of which 5344 were treated for CRSwNP. The prevalence of DA‐GOR and DA‐OSR was greatest for AD (15.3%, 7.8%), followed by CRSwNP (12.2%, 6.7%) and asthma (9.2%, 3.5%). The most commonly reported OSRs were dry eyes (35.9%), conjunctivitis (15.7%), and increased lacrimation (11.0%). The reported odds ratio (ROR) of CRSwNP‐treated DA‐OSR was 0.84 (0.73–0.97; p = 0.015), compared to 1.29 (1.20–1.40; p < 0.001) for AD and 0.66 (0.59–0.73; p < 0.001) for asthma. For CRSwNP treatment, the DA‐OSR ROR was 0.97 (0.90–1.03; p = 0.3) for men and 0.78 (0.73–0.83, p < 0.001) for older adults (age > 50). ROR in the DPA for DA‐OSR was 12.5 (12.2–12.8; p < 0.001) for any indication and 0.58 (0.53–0.64; p < 0.001) for CRSwNP treatment only. Conclusions: While there are limitations to FAERS, this study confirms the association between dupilumab and OSR for AD treatment, and does not support an association between dupilumab and OSR for CRSwNP treatment. Younger adults experience more DA‐OSR in CRSwNP treatment without a specific predilection for sex. Level of Evidence: IV Laryngoscope, 134:2602–2608, 2024 [ABSTRACT FROM AUTHOR]

Coloboma, congenital heart disease, ichthyosiform dermatosis, intellectual disability, conductive hearing loss, and epilepsy (CHIME) syndrome is a rare autosomal recessive neuroectodermal disorder caused by PIGL gene mutations. There is emerging literature to support the use of interleukin‐17 (IL‐17) antagonists in the treatment of certain ichthyosiform dermatoses. Here, we report a case of severe ichthyosiform dermatosis in a child with CHIME syndrome who was recalcitrant to multiple topical medications and dupilumab. This is the first reported case of successful treatment of congenital ichthyosiform dermatosis in a CHIME syndrome patient with ixekizumab, an IL‐17A antagonist. [ABSTRACT FROM AUTHOR]

This article discusses the use of dupilumab, a medication, for the treatment of chronic actinic dermatitis (CAD), a rare photosensitive disorder that primarily affects older men. The article presents two case studies of patients with CAD who were successfully treated with dupilumab, showing significant improvement in their symptoms. The article also reviews existing literature on the use of dupilumab for CAD and suggests the need for further studies to confirm its effectiveness. The document is a case series that includes information on patients with various medical conditions and the treatments they received, predominantly male patients treated with medications like hydroxychloroquine, methotrexate, and mycophenolate mofetil. The document also provides information on abbreviations used and conflicts of interest of the authors. Ethical approval was not required for this case series, and patient consent was obtained for the use of their information and images. [Extracted from the article]

Kimura disease (KD) is a rare, chronic angiolymphoproliferative inflammatory disease appearing to be mostly restricted to the skin and soft tissue. Cutaneous involvement of KD includes head and/or neck nodules showing suggestive histological features, frequently associated with an atopic dermatitis-like or prurigo-like presentation. KD is challenging to treat, with high rate of recurrence using current therapeutic strategies. Evidence for involvement of a T-helper type 2 (Th2) immune response in KD pathogenesis has been found in previous studies. Consequently, this study aimed to determine the efficacy and safety of dupilumab, a human monoclonal antibody that inhibits signalling of key Th2 cytokines, interleukin (IL)-4 and IL-13, within a single-centre cohort of patients with cutaneous KD. Two adults with a diagnosis of refractory (failure of at least one treatment line) cutaneous-restricted KD based on clinical, biological, histological, molecular and imaging findings received dupilumab for KD, and showed dramatic response with a good safety profile.

Chronic rhinosinusitis with nasal polyps (CRSwNP) in the severe forms is associated with a poor quality of life. Dupilumab has been suggested as an add-on treatment option for severe CRSwNP. Severe CRSwNP patients treated with Dupilumab in different rhinological units were considered for this study via their evaluation at the baseline at first and the consequential follow-up at 6-, 12-, and 24 months from the first administration. At baseline (T0) and at each follow-up, patients underwent NPS, Sinonasal Outcome Test (SNOT)-22, Visual Analogue Scale (VAS) for smell, and Sniffin' sticks identification test (SSIT). The SNOT-22 domains for function and emotion were also analysed separately. Two hundred and seventeen patients with at least 6 months of follow-up were included. All parameters have improved during treatment (p < 0.0001). Noticeably, both the function and emotion SNOT-22 domains have improved within 6 months of treatment and have continued to progress during every interval within 12 months from the baseline, positively influencing patients' emotivity and augmenting their social and economic performances. Dupilumab improves the QoL of CRSwNP patients with good effects on the reported productivity and emotional health. Clinicians should pay attention to these two aspects when dealing with patients affected by severe CRSwNP. [ABSTRACT FROM AUTHOR]

This article presents a real-world study conducted at Ruijin Hospital in Shanghai, China, to evaluate the efficacy and safety of Dupilumab, a monoclonal antibody used to treat atopic dermatitis (AD) in Chinese patients. The study included 689 patients of all ages who were treated with Dupilumab. The results showed that Dupilumab was effective in reducing symptoms of AD, with the greatest improvement observed in the first 8 weeks of treatment. Factors such as age, gender, and baseline eosinophil counts were found to influence the therapeutic effect. The incidence of adverse events was generally low, with most events being mild and tolerable. Some rare infections, phenotype switching, and tumor events were also observed. The study provides valuable insights into the efficacy and safety of Dupilumab in the Chinese population. [Extracted from the article]

This article discusses the efficacy of dupilumab in the treatment of palmoplantar pustulosis (PPP), a chronic skin disease characterized by pustules and scaling on the palms and soles. The study found that dupilumab, an antibody that targets IL-4Rα and inhibits IL-4 and IL-13 signaling, was effective in treating PPP in a group of 10 Asian Chinese patients. The patients achieved significant improvement in their symptoms, with no recurrence of disease flare or adverse events. The study also identified serum biomarkers associated with PPP that were similar to those found in atopic dermatitis and psoriasis patients. Further research is needed to better understand the pathogenesis of PPP and guide its diagnosis and treatment. [Extracted from the article]

Background: Lung function is an independent predictor of mortality. We evaluated the lung function trajectories of a cohort of patients with asthma receiving biologic therapy. Methods: We identified 229 monoclonal antibody‐naïve adult patients with moderate‐to‐severe asthma who initiated omalizumab, mepolizumab, or dupilumab between 2010 and 2022 in a large healthcare system in Boston, MA. Generalized additive mixed models were used to estimate the lung function trajectories during the 156 weeks following biologic initiation. Response was defined as an improvement in FEV1 or a decrease of ≤0.5% per year. The Kaplan–Meier estimator was used to assess time to no additional improvement in FEV1 in responders. All models were adjusted for age, sex, body mass index, smoking status, baseline exacerbation rate, and baseline blood eosinophil count. Results: Eighty‐eight patients initiated mepolizumab, 76 omalizumab, and 65 dupilumab. Baseline eosinophil count was highest in the mepolizumab group (405 cells/mcL) and lowest for omalizumab (250 cells/mcL). Both FEV1 and FVC improved in the mepolizumab group (FEV1 + 20 mL/year; FVC +43 mL/year). For omalizumab, there was an initial improvement in the first year followed by decline with an overall FEV1 loss of −44 mL/year and FVC −32 mL/year. For dupilumab, both FEV1 (+61 mL/year) and FVC (+74 mL/year) improved over time. Fifty percent of the mepolizumab group, 58% omalizumab, and 72% of dupilumab were responders. The median time to no additional FEV1 improvement in responders was 24 weeks for omalizumab, 48 weeks for mepolizumab, and 57 weeks for dupilumab. Conclusion: In this clinical cohort, mepolizumab, omalizumab, and dupilumab had beneficial effects on FEV1 and FVC with distinct post‐initiation trajectories. [ABSTRACT FROM AUTHOR]

Purpose: Induced eosinophilia is commonly related to dupilumab treatment. We analysed the temporal trends of blood eosinophilia in patients with severe uncontrolled CRSwNP during the first year of treatment with dupilumab in real-life setting to evaluate its correlation with outcomes of response and adverse events (AEs). Methods: Seventy-four patients with severe uncontrolled CRSwNP treated with dupilumab at our institution were enrolled. At each visit, we evaluated AEC, outcomes of response to treatment and AEs. Results: A significant increase in AEC was observed since the first month with a peak at 3 months; at 12 months, the values returned comparable to those at baseline. A ≥ 50% increase of the baseline AEC with a value greater than 500 cells/mm3 was documented in 38/74 patients (Group A) regardless of the time of observation, whereas in 36/74 patients (Group B), no changes were observed. Analysing the blood eosinophilia trend over time in group A, we observed a temporary eosinophilia with early onset (within 6 months), persistent eosinophilia with early onset, and eosinophilia with late onset. No differences in terms of outcomes of response to treatment or AEs were found between Group A and Group B, or between patients who developed an AEC ≥ 1500 cells/mm3 or not. Conclusion: In our series, we observed that an increase in AEC with different temporal trends may be observed in CRSwNP patients during the first year of treatment with dupilumab. In our series, eosinophilia is not correlated with a negative outcome of response to treatment or a risk of AEs. [ABSTRACT FROM AUTHOR]

Ischemic heart failure continues to be a highly prevalent disease among westernized countries and there is great interest in understanding the mechanisms preventing or exacerbating disease progression. The literature suggests an important role for the activation of interleukin-13 or interleukin-4 signaling in improving ischemic heart failure outcomes after myocardial infarction in mice. Dupilumab, a neutralizing antibody that inhibits the shared IL13/IL4 receptor subunit IL4Rα, is widely used for conditions such as ectopic dermatitis in humans. If global depletion of IL4Rα influences ischemic heart failure, either in mice or in humans taking dupilumab, is unknown. Here, we investigated the pathophysiological effects of global IL4Rα genetic deletion in adult mice after surgically induced myocardial infarction (MI). We also determined heart failure risk in patients with ischemic heart disease and concomitant usage of dupilumab using the collaborative patient data network TriNetX. Global deletion of IL4Rα results in exacerbated cardiac dysfunction associated with reduced capillary size after myocardial infarction in mice. In agreement with our findings in mice, dupilumab treatment significantly increased the risk of heart failure development in patients with preexisting diagnosis of ischemic heart disease. Our results indicate that systemic IL4Rα signaling is protective against heart failure development in adult mice and human patients specifically following an ischemic event. Thus, the compelling evidence presented hereby advocates for the development of a randomized clinical trial specifically investigating heart failure development after myocardial ischemia in patients taking dupilumab for another underlying condition. NEW & NOTEWORTHY A body of literature suggests a protective role for IL4Rα signaling postmyocardial infarction in mice. Here, our observational study demonstrates that humans taking the IL4Rα neutralizing antibody, dupilumab, have increased incidence of heart failure following an ischemic event. Similarly, global IL4Rα deletion in mice exacerbates heart failure postinfarct. To our knowledge, this is the first study reporting an adverse association in humans of dupilumab use with heart failure following a cardiac ischemic event. [ABSTRACT FROM AUTHOR]

Atopic dermatitis (AD) diagnosis in elderly is challenging, due to its clinical polymorphism and the lack of diagnostic biomarkers. Moreover, the chronicity of the disease and the complex pathogenetic mechanism, make elderly AD management challenging. A narrative review of the current literature was performed using the PubMed, Medline, Embase, and Cochrane Skin databases, by researching the following terms: 'atopic dermatitis,' 'clinical phenotypes,' 'eczema,' 'elderly patients,' 'elderly type atopic dermatitis,' 'eczema clinical presentation.' The aim was to report the current knowledge on pathogenesis, clinical presentation, and treatment options of elderly AD. Elderly type AD has recently been identified as a separate entity, with an increasing prevalence. With aging, both immunosenescence and barrier alterations can cause or modify AD presentation. Moreover, a chronic proinflammatory state (so-called 'inflammaging') is often present in elderly subjects. Older patients with AD may present with peculiar immunophenotypic profile, making AD diagnosis challenging. Similarly, the chronicity of the disease and the complex pathogenetic mechanism, make AD management a challenge. Indeed, systemic therapies for AD are often contraindicated or not tolerated and the management of elderly type AD is often burdened with numerous difficulties, leading to undertreated disease. Even if dupilumab and tralokinumab represent a valuable therapeutic weapon, more data on safety of JAK inhibitors are required. [ABSTRACT FROM AUTHOR]

Allergic contact dermatitis (ACD) is a common cutaneous inflammatory skin disorder that is diagnosed via epicutaneous patch testing (PT). ACD may also coexist with other systemic inflammatory conditions such as atopic dermatitis and psoriasis. Many of the treatments used to manage severe ACD, along with other systemic conditions, interact with and suppress the immune system, thereby potentially interfering with the mechanism of PT. There is uncertainty in the literature regarding the effects of immunosuppression on the results of PT. A comprehensive literature review was conducted using PubMed and Google Scholar to identify articles relevant to the topic of this review. Only articles available in English were included. This review discusses the impact of immunomodulating therapies on the results of PT. We summarize the available evidence and provide updated recommendations for several immunomodulating drugs commonly used in patients undergoing PT. In general, the results of PT are most reliable when performed without immunosuppression. If this is not feasible, it is best to have patients on as low a dose of immunosuppression as possible, but it may not be necessary to stop or change an immunomodulating drug prior to PT.

Lichen amyloidosis (LA) is a type of cutaneous amyloidosis characterized by brownish hyperkeratotic and itchy papules on the lower leg, back, forearm, or thigh. It is associated with itching and atopic dermatitis (AD) according to an etiopathogenetic mechanism that has not yet been fully elucidated. Currently, the available therapies for this condition include oral antihistamines, laser, cyclosporine, topical corticosteroids, and phototherapy, but, in light of the overlap with AD, Dupilumab may also be indicated. We report the case of a female, 52 years old, who had been suffering from AD and LA for about 27 years. She had lesions attributable to both diseases on the trunk and lower limbs associated with severe itching and had proved resistant to cyclosporine therapy. It was decided to opt for Dupilumab with the induction of 2 fl of 300 mg and maintenance with 1 fl every other week. The therapy proved to be effective, returning a total resolution of both diseases one year after the beginning of the treatment. Dupilumab demonstrated efficacy and safety in the LA related to AD and led to clinical and quality of life improvements in this patient. Therefore, Dupilumab should be considered when treating LA. Further studies should be conducted focusing on the efficacy of the drug on LA (whether or not related to AD), changes in the skin lesions after discontinuation, and the safety of long-term application.

The introduction of high-cost medications often poses challenges in achieving cost-effectiveness for drug insurance coverage. Incorporating future price reductions for these medications may enhance their cost-effectiveness. We examined the influence of future cost reductions mandated by the national insurer's equal pricing for equivalent drugs (EPED) policy on the cost-effectiveness of dupilumab, a biologic drug for moderate to severe atopic dermatitis in the Korean healthcare system. We conducted a policy simulation study using semi-Markovian cost utility analysis of dupilumab in combination with supportive care (SC) versus SC alone, with and without the EPED policy adjustment. The EPED would lower dupilumab's price to 70% following the entry of a biosimilar drug in 10.3 years. Scenario analyses quantified the impact of changing time to the EPED, chemical versus biological designation, response criteria, discount rates, and time horizons on the Incremental Cost-Effectiveness Ratio (ICER) and acceptability with and without EPED adjustment. The EPED adjustment of dupilumab's future price significantly improved its cost-effectiveness, with a 9.7% decrease in ICER and a substantial 14.6% increase in acceptability. Assuming EPED in 5 years, the ICER fell below the predefined willingness-to-pay threshold. If dupilumab were a chemical drug, EPED adjustment demonstrated a 19.1% increase in acceptability. Incorporating future cost reductions via the EPED system in economic evaluations is crucial, especially for drugs facing imminent generic entry. This study underscores the importance of EPED adjustment in the cost-effectiveness analysis of innovative medications, especially for those nearing willingness-to-pay thresholds.

To date, the pathogenesis of Kimura’s disease remains unclear, there is no unified diagnostic criterion, the clinical phenotype shows considerable heterogeneity, and there is a lack of optimal treatment strategies. Due to its rarity, treatment strategies for KD are still under exploration. This paper reports a case of a 37-year-old Chinese female presenting with generalized erythematous papules and pruritic eruptions for 12 years, followed by the onset of limb swellings 3 years later, ultimately diagnosed as Kimura’s disease. Considering the patient’s multiple lymphadenopathies and limb swellings with concurrent atopic dermatitis, the treatment regimen included initial dupilumab dosage of 600 mg (300 mg administered in two injections), followed by subcutaneous injections of 300 mg every two weeks for four months. Concurrent oral corticosteroid therapy (methylprednisolone, initial dose 16 mg/kg/day, gradually tapered with tumor regression) was also administered. Following treatment, the patient did not experience severe adverse effects, and the multiple nodules markedly decreased in size. Additionally, serum IgE levels, eosinophil, and basophil counts showed significant reductions. These results demonstrate the significant efficacy of dupilumab combined with oral corticosteroids in treating Kimura’s disease with concurrent atopic dermatitis.

Beyond Th2 cells and various immune cells, M2 macrophages have been identified in lesional skin of atopic dermatitis (AD) indicating their involvement in the disease’s underlying mechanisms. MMP12, a matrix-degrading enzyme, which is predominantly produced by macrophages, is increased in skin lesions of AD patients. In this study we investigated the expression of MMP12 mRNA in lesional AD skin at single cell level through RNA sequencing (scRNA-seq) and the expression of MMP12 in M2 macrophages from healthy individuals and AD patients in response to Th2 cytokines and histamine using quantitative PCR and ELISA. Additionally, we analyzed macrophages from dupilumab-treated AD patients using the same methods to assess the influence of Th2 cytokines on MMP12 expression ex-vivo. ScRNA-seq identified macrophages as the primary producers of MMP12 in lesional AD skin. In-vitro, both MMP12 mRNA and protein expression were significantly increased in monocytes during differentiation to M2 macrophages in the presence of histamine, of Th2 cytokines or of Th2 cytokines in combination with histamine. In M2 macrophages obtained from dupilumab-treated AD patients, the upregulation of MMP12 expression by IL-4 and IL-13 was attenuated. Our findings unveil a novel mechanism whereby Th2 cytokines and histamine regulate MMP12 expression, potentially impacting skin barrier homeostasis in AD.

Background: Guidelines for chronic rhinosinusitis (CRS) propose total IgE and eosinophils as important biomarkers to identify type-2 inflammation. Despite the fact that specific IgE (sIgE) have been identified as a clinical predictor in some type-2 diseases for different clinical outcomes, its role in CRS has yet to be explored in detail. Objetive: To describe systemic and local sIgE in CRS and explore its possible association with clinical outcomes using nasal challenge tests (NCT). Methods: In CRS patients, we measure total IgE, serum sIgE (SsIgE) and nasosinusal sIgE (NsIgE) against 9 allergenic sources; Der p, Der f, Blo t, Can f, Fel d, Per a, grasses, Staphylococcus enterotoxin A, and B. NCT was done using the allergen with the higher sIgE prevalence (Der p). Results: A total of 174 patients were included. Prevalence of SsIgE was 52.8% and NsIgE 46.5%; Der p was the principal allergen for SsIgE and NsIgE. The presence of nasal polyps, asthma comorbidity, NSAID hypersensitivity, and hyposmia, were significantly associated with the presence of SsIgE and NsIgE but not with total IgE. NCT-Der p was performed in 73 CRS patients, being positive in 33 (45.2%). SsIgE have the best diagnostic accuracy (79.4%) to predict NCT results (NsIgE 67.5% total IgE 52%). Conclusion: Specific IgE is a better biomarker in CRS than total IgE. Patients with clinically relevant SsIgE have a pheno-endotype associated with different clinical outcomes. Considering the clinical relevance of SsIgE demonstrated by NCT, interventions like allergen immunotherapy in CRS must be study.

Abstract Immune checkpoint inhibitors (ICI) are increasingly utilized as first‐line treatment for many solid tumour malignancies. One downside of ICI therapy is autoimmune‐mediated organ inflammation, or immune‐related adverse events (irAE). ICI‐related pneumonitis, or non‐infectious inflammation of the lung, is a well‐described irAE. While guidelines surrounding ICI‐related pneumonitis are well established, other ICI‐related pulmonary toxicities, including reactive airways disease, are rarely described in the literature. Here, we present a series of patients without pre‐existing COPD or asthma who developed reactive airways disease with peripheral eosinophilia after ICI therapy and without radiographic evidence of pneumonitis. The patients were treated with typical therapies for reactive airways disease, including– inhaled steroids, bronchodilators, systemic steroids, and in one instance, dupilumab. All experienced symptomatic improvement with these therapies, enabling some of the patients to continue receiving ICI therapy.

Exercise-induced anaphylaxis (EIA) is a rare and potentially life-threatening disorder. In difficult to control and refractory cases of EIA, biologics such as omalizumab and dupilumab have shown promise, with documented successful outcomes. Here, we present a case of EIA with lipid transfer protein (LTP) sensitization successfully treated with omalizumab with long-term follow-up. A 12-year-old girl presented to our allergy department because of recurrent episodes of EIA, with no specific food ingestion before exercise. Allergen testing revealed sensitization to weed pollens, particularly mugwort (76.1 kUA/L) and Alternaria alternata (10.8 kUA/L). Allergen component testing indicated sensitization to LTP components from mugwort Art v 3 (49.9 kUA/L), wheat Tri a 14 (2.03 kUA/L), and peach Pru p 3 (11.5 kUA/L), with a negative result for omega-5 gliadin. Despite initial prophylactic treatment with budesonide–formoterol (80/4.5 μg) and cetirizine (10 mg) before exercise, the patient still experienced EIA; she was then recommended for dupilumab therapy (an initial dose of 600 mg, followed by 300 mg every 2 weeks for six doses). However, even while undergoing dupilumab therapy, she suffered two anaphylactic episodes after running 800–1,000 m. With the patient's consent, a trial of omalizumab was initiated (injections of 300 mg every 4 weeks). After 2 months of omalizumab therapy, the patient showed significant improvement. She had been engaging in physical exercise three times a week and experienced a mild episode of urticaria. There were no further episodes of anaphylaxis or emergency room visits. By the fourth month of omalizumab treatment, she was able to consume food normally even just before exercising and had returned to her full activity level without any restrictions. This case presents the first successful off-label use of omalizumab in the prevention of EIA in the Chinese population. It is concluded that omalizumab may be helpful in resolving EIA symptoms, as evidenced by this case of successful long-term use.

BackgroundModerate-to-severe atopic dermatitis (AD) often has a profound impact on the quality of life of young children and their caregivers. One of the most burdensome symptoms reported by patients is skin pain.MethodsThis post hoc analysis focuses on the impact of dupilumab treatment on skin pain in young children using data from the LIBERTY AD PRESCHOOL part B (NCT03346434), a 16-week randomized, double-blind, placebo-controlled, phase 3 study in 162 children aged 6 months to 5 years with moderate-to-severe AD receiving dupilumab or placebo, plus topical corticosteroids (TCS). Analyses were performed on the full analysis set and subgroups of patients who did not achieve an Investigator's Global Assessment score of 0 or 1 (IGA >1 subgroup), or who did not achieve a 75% improvement from baseline in the Eczema Area and Severity Index (1 and

Abstract Introduction Recent evidence recommends the use of biologics in patients with severe uncontrolled type 2 chronic rhinosinusitis with nasal polyp (CRSwNP) owing to its propensity for recurrence after functional endoscopic sinus surgery (FESS). Among the type 2 biologics used for the treatment of nasal polyps, dupilumab (Dupi, anti‐IL‐4) exhibited superior efficacy and safety in indirect comparison studies. Objective This study aimed to evaluate the objective and subjective outcomes of patients with CRSwNP treated with and without adjuvant Dupi therapy after FESS. Methods Adult patients with type 2 CRSwNP who underwent FESS with adjuvant Dupi after surgery were enrolled. A matched control group without adjuvant Dupi therapy were recruited during the same period. All patients underwent nasal endoscopy and completed the sinonasal outcome test‐22 questionnaire evaluations at baseline and 3 months after surgery. Results A total of 10 patients who received postoperative adjuvant therapy with Dupi and 20 patients who underwent surgery only were included. Patients with add‐on Dupi therapy had significantly higher eosinophil cationic protein levels in the serum, eosinophil counts in peripheral blood, prevalence of asthma, and nasal polyp score at baseline. Both treatments were effective in reducing the patient's symptoms by SNOT‐22 at 3 months postoperatively. However, patients with adjuvant Dupi therapy exhibited significantly better endoscopic scores than those with surgery only (p = .022). Conclusion Surgery plays an important role in treating patients with CRSwNP, and adjuvant Dupi use may facilitate objective mucosal recovery postoperatively. Level of Evidence 4.

Abstract Background Dupilumab has been shown to be an effective treatment in moderate‐to‐severe atopic dermatitis (AD) and severe asthma (SA). However, comparative real‐world analyses of adverse events (AE), particularly dupilumab‐associated ocular surface disease (DAOSD), are lacking. Objective This is the first real‐world study to provide insight into the prevalence of AEs associated with dupilumab in AD compared with SA. Secondary objectives were to assess the prevalence, onset and therapeutic strategies of DAOSD and evaluate dupilumab discontinuation rates. Methods Data from two daily practice registries including AD and SA patients receiving dupilumab treatment were analyzed. Adverse events, including DAOSD, were evaluated. Results In total, 322 AD and 148 SA patients were included. Headaches (23.6%), injection site reactions (10.1%), and influenza‐like symptoms (13.5%) were more prevalent in SA patients. Interestingly, ocular AEs were significantly more prevalent in AD patients (62.1%, p

Key message It is an absolute necessity to achieve complete control of comorbidities to obtain optimal asthma control. Importantly, type 2 asthma and ECRS share the same inflammatory pathophysiology and are common co‐morbidities. If the initial biologic is insufficiently effective, it is worth considering an alternative biologic.

Dupilumab was approved for the treatment of several dermatologic immune-mediated inflammatory diseases, such as atopic dermatitis and bullous pemphigoid; whereas omalizumab is the first biological agent which was approved to treat chronic spontaneous urticaria. None of the published meta-analyses has provided the sufficient data regarding the safety of these two biologics, especially regarding their potential serious adverse events (SAEs). The aim of this study was, to comprehensively evaluate the safety of the two biologics dupilumab and omalizumab. In this study, we included 32 randomized trials, and performed meta-analyses on 113 types of SAEs regarding dupilumab and 61 types of SAEs regarding omalizumab. We identified that: (1) use of dupilumab was significantly associated with the lower incidence of atopic dermatitis, while use of omalizumab was significantly associated with the lower incidence of asthma; and (2) use of dupilumab was not significantly associated with the incidences of 112 other kinds of SAEs including various infectious diseases, while use of omalizumab was not significantly associated with the incidences of 60 other kinds of SAEs including various infectious diseases. This meta-analysis for the first time assessed the association between use of dupilumab or omalizumab and incidences of various SAEs, and identified that neither dupilumab use nor omalizumab use was associated with the increased risks of any SAEs including various infectious diseases. These findings further confirm the general safety of the two biologics dupilumab and omalizumab. This informs clinicians that there is no need to worry too much about the safety issues of these two biologics.

Background: Type 2 inflammation is the principal determinant of asthma in children, and it leads to the downstream activation of eosinophils (EOS), the production of immunoglobulin-E (IgE), and increased levels of fraction of exhaled nitric oxide (FeNO). Dupilumab received the approval for the treatment of uncontrolled severe Type 2 asthma in children. Objective: The aim of this analysis was to calculate the Type 2 severe asthma paediatric population who would be eligible for treatment with dupilumab in Italy and characterize them by expected biomarker status. Methods: The calculation of the dupilumab-eligible population employed a two-phase approach: 1) estimating the total number of children aged 6–11 years with uncontrolled severe asthma; and 2) stratifying the severe uncontrolled asthma population, based on appropriate biomarker levels, thus identifying patients eligible for treatment with dupilumab. The VOYAGE study provided the data for this analysis. Results: The two-phase approach utilizing VOYAGE data revealed that the average number of paediatric patients with uncontrolled severe asthma was N = 1007. Stratification of these patients, as per VOYAGE data, indicated that the majority (N = 740; 73.5%) would have ≥2 elevated biomarkers, and over one-third patients (N = 434, 43.1%) would exhibit simultaneously elevated levels of EOS, FeNO and IgE. Of the paediatric patients, N = 864 were identified as eligible to dupilumab treatment, constituting 85.8% of the target population. Notably, nearly half eligible patients (N = 454) displayed elevated levels of both EOS and FeNO biomarkers, while the substantial majority (81.1%) exhibited at least an increase of EOS levels (N = 817). Patients with increased FeNO levels without a concurrent increase in EOS were less frequent (N = 47; 5.4% of the eligible population). Conclusion: The simultaneous testing of multiple biomarkers during baseline patient assessment and disease follow-up is highly recommended. Utilizing cost-effective tests, physicians can estimate the prevalence of severe Type 2 asthma, categorize patients into distinct phenotypes (eosinophilic, allergic, or mixed), and consequently identify and prescribe the most suitable therapeutic interventions. This approach also facilitates the ongoing evaluation and adjustment of the treatment strategies based on individual patient responses.

Key points Dupilumab targets Th2‐associated inflammatory mediators to reduce disease burden in CRSwNP. While rare, potential sequelae include viral, helminth, and potentially amebic infections. [ABSTRACT FROM AUTHOR]

This document presents a study on the effectiveness and safety of dupilumab, a systemic treatment for atopic dermatitis, in adolescents. The study followed 94 adolescents over a period of up to 3 years and found that dupilumab consistently improved clinical scores and maintained minimal disease activity in the majority of patients. Adverse events were rare, with only a small percentage of patients experiencing temporary eosinophilia or mild conjunctivitis. The study concludes that dupilumab is a safe and effective long-term option for adolescents with severe atopic dermatitis. [Extracted from the article]

This article compares the efficacy of two biologic drugs, benralizumab and dupilumab, in treating airway hyperresponsiveness (AHR) in patients with uncontrolled type 2 high severe asthma. The study found that dupilumab was more effective than benralizumab in improving AHR and inducing AHR remission. The patients taking dupilumab were also able to reduce their daily dose of inhaled corticosteroids. The study suggests that further research is needed to confirm these findings through direct head-to-head evaluation. [Extracted from the article]
