Omalizumab in the treatment of Morbihan syndrome in an adolescent girl – case report and literature review

Morbihan syndrome (MS) is characterized by solid facial edema, usually related to rosacea or acne vulgaris. The facial edema deforms the patient’s features, can impair peripheral vision, and affects quality of life. Its pathophysiology remains unclear. The disease usually has a slow and chronic course. MS most commonly affects middle-aged Caucasian men with rosacea and is rare in people below 20 years of age. MS is a diagnosis of exclusion. There is no standard treatment for MS, though systemic isotretinoin and antihistamines are mainly used. We present the case of an adolescent girl with MS nonresponding to 19 months of isotretinoin treatment with add-on antihistamines. Therapy with monthly administration of omalizumab (anti-IgE) for 6 months was an effective therapeutic option, improving the quality of life. Our case is the second description of omalizumab use in Morbihan syndrome, the first in an adolescent. (AU)

Comparison of Long-term Response and Remission to Omalizumab and Anti-IL-5/IL-5R Using Different Criteria in a Real-life Cohort of Severe Asthma Patients

Background: Evaluation of biologic therapy response is vital to monitor its effectiveness. Authors have proposed various response criteria including good responder, super-responder, non-responder, and clinical remission.ObjectivesTo ascertain the prevalence of response and clinical remission after long-term treatment (>6 months) of anti-IgE and anti-IL-5/IL-5Rα biologics, compare these results with existing criteria, and identify predictors for non-responders and clinical remission.MethodsA multicenter, real-life study involving severe asthma patients in Spain. Various outcomes were assessed to gauge response and clinical remission against established criteria.ResultsThe study included 429 patients, 209 (48.7%) omalizumab, 112 (26.1%) mepolizumab, 19 (4.4%) reslizumab and 89 (20.7%) benralizumab, with a mean treatment duration of 55.3±38.8 months. In the final year of treatment, 218 (50.8%) were super-responders, 173 (40.3%) responders, 38 (8.9%) non-responders, and clinical remission in 116 (27%), without differences among biologics. The short-term non-responders (<6 months) were 25/545 (4.6%). Substantial variations in response and clinical remission were observed when applying different published criteria. Predictors of non-response included higher BMI (OR:1.14; 95% CI:1.06–1.23; p<0.001), admissions at ICU (2.69; 1.30–5.56; p=0.01), high count of SAE (1.21; 1.03–1.42; p=0.02) before biologic treatment. High FEV1% (0.96; 0.95–0.98; p<0.001), a high ACT score (0.93; 0.88–0.99; p=0.01) before biologic treatment or NSAID-ERD (0.52; 0.29–0.91; p=0.02) showed strong associations with achieving clinical remission.ConclusionA substantial proportion of severe asthma patients treated long-term with omalizumab or anti-IL5/IL-5Rα achieved a good response. Differences in response criteria highlight the need for harmonization in defining response and clinical remission in biologic therapy to enable meaningful cross-study comparisons. (AU)

The Role of Adjuvant Therapy in the Management of Chronic Urticaria / El papel de la terapia adyuvante en el tratamiento de la urticaria crónica espontánea

Recent guideline on the management of urticaria recommends second-generation H1-antihistamine as the first-line therapy, with dose increases of up to fourfold if inadequately controlled. However, the treatment of chronic spontaneous urticaria (CSU) is often disappointing, so additional adjuvant therapies are needed to increase the effectiveness of first-line therapy, especially in patients who are refractory to the increase of antihistamine doses. Recent studies recommend various adjuvant therapy modalities for CSU, such as biological agents, immunosuppressants, leukotriene receptor antagonists, H2-antihistamine, sulfones, autologous serum therapy, phototherapy, vitamin D, antioxidants, and probiotics. This literature review was made to determine the effectiveness of various adjuvant therapies in managing CSU (AU)

Las directrices actuales para el tratamiento de la urticaria crónica recomiendan los antihistamínicos H1 de segunda generación como tratamiento de primera línea, con un aumento de hasta 4 veces la dosis si no se controla. Sin embargo, la terapia en la urticaria crónica espontánea suele ser decepcionante, por lo que es necesario un tratamiento adyuvante adicional para mejorar la eficacia de la terapia, especialmente en los pacientes que son refractarios a dosis mayores de antihistamínicos. Las investigaciones más recientes recomiendan varias modalidades de tratamiento adyuvante para la urticaria crónica espontánea, como los agentes biológicos, los inmunosupresores, los antagonistas de los receptores de leucotrienos, los antihistamínicos H2, las sulfonas, la terapia con suero autólogo, la fototerapia, la vitamina D, los antioxidantes y los probióticos. Esta revisión bibliográfica presenta estudios recientes sobre la eficacia de diversas terapias adyuvantes en el tratamiento de la urticaria crónica espontánea (AU)

Improvement in Smell Using Monoclonal Antibodies Among Patients With Chronic Rhinosinusitis With Nasal Polyps: A Systematic Review

Background: Impairment of smell is more commonly related to chronic rhinosinusitis with nasal polyps (CRSwNP) than without, especially when asthma and/or NSAID-exacerbated respiratory disease and type 2 inflammation are also present. Therapeutic options include intranasal and systemic corticosteroids, surgery, and, more recently, biological therapy. We summarize current knowledge on the effect of biologics on olfaction in patients with CRSwNP.Methods: We performed a systematic search of the PubMed and Cochrane databases from January 2001 to June 2022. The inclusion criteria were as follows: adult patients with CRS treated with dupilumab, omalizumab, mepolizumab, benralizumab, or reslizumab; and studies published in English reporting outcomes for sense of smell based on psychophysical and/or subjective tools. We excluded reports that did not assess CRSwNP, loss of smell evaluated with a method other than those accepted in the inclusion criteria, review articles, and expert opinions. No funding was received.Results: Dupilumab has demonstrated rapid and sustained long-term improvement in smell in clinical trials and in real life. Omalizumab improves smell at 24 weeks. This improvement is maintained in the long-term, although it is not clinically relevant. Mepolizumab and benralizumab improved smell in the long term based on a subjective scale. No studies examining the improvement in smell in patients with CRSwNP treated with reslizumab were found. Indirect comparisons by meta-analysis consistently conclude that dupilumab is the most effective biologic for improving impaired sense of smell.Conclusion: Dupilumab seems to be more efficacious for improving the sense of smell than omalizumab, mepolizumab, and benralizumab. (AU)

Antecedentes: La pérdida de olfato de la rinosinusitis crónica se relaciona principalmente con el fenotipo que presenta poliposis nasal (RSCcPN), especialmente si asocia asma y/o EREA, e inflamación tipo 2. Los corticoides intranasales y sistémicos, la cirugía y, de forma más reciente, los fármacos biológicos, constituyen las principales estrategias terapéuticas. Este documento contiene una revisión sistemática del efecto de los fármacos biológicos en el olfato de pacientes con RSCcPN. Métodos: Se realizó una búsqueda sistemática en las bases de datos PubMed y Cochrane desde enero de 2001 hasta junio de 2022. Los criterios de inclusión fueron: pacientes adultos con RSC tratados con dupilumab, omalizumab, mepolizumab, benralizumab o reslizumab; estudios publicados en inglés, con datos sobre la mejoría del olfato utilizando test psicofísicos y/o subjetivos. Los criterios de exclusión fueron: publicaciones que no incluían pacientes con poliposis nasal, la pérdida del olfato evaluada con un método diferente de los criterios de inclusión mencionados, los artículos de revisión y la opinión de expertos. No se empleó ningún recurso de financiación. Resultados: Dupilumab ha demostrado una mejora del olfato rápida y mantenida a largo plazo en ensayos clínicos y en la práctica clínica habitual. Omalizumab mejora el olfato en la 24ª semana y lo mantiene a largo plazo, pero no alcanza una mejoría clínicamente relevante. Mepolizumab y benralizumab mejoran el olfato a largo plazo, evaluado mediante un test subjetivo. No se encontraron estudios respecto a la mejoría del olfato en pacientes con RSCcPN tratados con reslizumab. Las comparaciones indirectas mediante metaanálisis concluyen de forma consistente que dupilumab es el biológico más eficaz para mejorar el sentido del olfato. Conclusión: Dupilumab es el biológico más eficaz en la mejoría del olfato en RSCcPN, en comparación con omalizumab, mepolizumab y benralizumab. (AU)

Effects of omalizumab combined with budesonide formoterol on clinical efficacy, pulmonary function, immune function, and adverse reactions in children with moderate and severe allergic asthma

Objective: To evaluate the clinical efficacy and safety of combining omalizumab with budesonide formoterol to treat children with moderate and severe allergic asthma, and investigate the effect of this combination therapy on pulmonary and immune functions. Methods: The data of 88 children with moderate and severe allergic asthma, who were admitted to our hospital between July 2021 and July 2022, were included in the study. The patients were randomly assigned either to control group (n = 44; received budesonide formoterol inhalation therapy) or experimental group (n = 44; received omalizumab subcutaneous injection + budesonide formoterol inhalation therapy) using computer-generated randomization. The clinical efficacy, asthma control (measured using childhood Asthma-Control Test [C-ACT] score), pulmonary function (forced expiratory volume in 1 s, forced vital capacity, and peak expiratory flow), immune function (cluster of differentiation 3 cells [CD3+ cells], cluster of differentiation 4 cells [CD4+ cells], immunoglobulin G, immunoglobulin A, and immunoglobulin E), and adverse reactions were observed and compared between both groups. Results: After treatment, the experimental group had improved levels of pulmonary function and immune function indexes, higher C-ACT scores, and a higher overall response rate than the control group (P < 0.05). In addition, the incidence of adverse reactions was not significantly different between both groups (P > 0.05). Conclusion: The combination of omalizumab with budesonide formoterol for treating moderate and severe allergic asthma in children demonstrated promising clinical efficacy and improved their pulmonary and immune functions, leading to more rational asthma control. The combined regimen demonstrated satisfactory clinical safety and deserved clinical promotion (AU)

Improvement in Olfaction in Patients With CRSwNP and Severe Asthma Taking Anti-IgE and Anti–IL-5 Biologics: A Real-Life Study

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP), which is characterized by partial loss of smell (hyposmia) or total loss of smell (anosmia), is commonly associated with asthma and/or nonsteroidal anti-inflammatory drug–exacerbated respiratory disease (N-ERD). CRSwNP worsens disease severity and quality of life. Objectives: The objective of this real-world study was to determine whether biological treatments prescribed for severe asthma can improve olfaction in patients with CRSwNP. A further objective was to compare the improvement in in olfaction in N-ERD and non–N-ERD subgroups.Methods: We performed a multicenter, noninterventional, retrospective, observational study of 206 patients with severe asthma and CRSwNP undergoing biological treatment (omalizumab, mepolizumab, benralizumab, or reslizumab). Results: Olfaction improved after treatment with all 4 monoclonal antibodies (omalizumab [35.8%], mepolizumab [35.4%], reslizumab [35.7%], and benralizumab [39.1%]), with no differences between the groups. Olfaction was more likely to improve in patients with atopy, more frequent use of short-course systemic corticosteroids, and larger polyp size. The proportion of patients whose olfaction improved was similar between the N-ERD (37%) and non–N-ERD (35.7%) groups. Conclusions: This is the first real-world study to compare improvement in olfaction among patients undergoing long-term treatment with omalizumab, mepolizumab, reslizumab, or benralizumab for severe asthma and associated CRSwNP. Approximately 4 out of 10 patients reported a subjective improvement in olfaction (with nonsignificant differences between biologic drugs). No differences were found for improved olfaction between the N-ERD and non–N-ERD groups (AU)

La rinosinusitis crónica con poliposis nasal (PN), caracterizada por la pérdida parcial o completa del olfato (hiposmia o anosmia, respectivamente), se asocia frecuentemente a asma y a enfermedad respiratoria exacerbada por ácido acetilsalicílico (EREA), lo cual implica una mayor gravedad y un deterioro adicional de la calidad de vida del paciente. Objetivos: El objetivo principal de este estudio fue determinar, en condiciones de vida real, si los tratamientos biológicos prescritos para asma grave mejoraban el olfato en aquellos pacientes que asociaban PN. Como objetivo secundario, se comparó la mejoría del olfato entre los subgrupos EREA y no EREA. Métodos: Se llevó a cabo un estudio multicéntrico, observacional, retrospectivo, que incluyó 206 pacientes con PN y asma grave en tratamiento con algún biológico (omalizumab, mepolizumab, benralizumab oreslizumab). Resultados: Se encontró mejoría del olfato con todos los biológicos: omalizumab (35,8%), mepolizumab (35,4%), reslizumab (35,7%) y benralizumab (39,1%), sin diferencias estadísticamente significativas entre ellos. Los pacientes con atopia, mayor uso de corticoides sistémicos y mayor tamaño de PN inicial, presentaron mayor mejoría. La proporción de pacientes que presentaron mejoría en el olfato fue similar entre el grupo EREA (37%) y no EREA (35,7%). Conclusiones: Se trata del primer estudio que compara, en condiciones de vida real, la mejoría del olfato en pacientes en tratamiento con omalizumab, mepolizumab, reslizumab o benralizumab indicados por asma grave que asociaban PN. Aproximadamente, 4 de cada 10 pacientes refirió mejoría subjetiva en el olfato (sin diferencias estadísticamente significativas entre los distintos biológicos). No se encontraron diferencias entre el grupo EREA y no EREA (AU)

Omalizumab and allergen immunotherapy for respiratory allergies: A mini-review from the Allergen-Immunotherapy Committee of the Italian Society of Pediatric Allergy and Immunology (SIAIP)

Although currently approved to treat severe asthma and chronic spontaneous urticaria, omalizumab has also been an effective and safe add-on treatment for other allergic diseases. Namely, omalizumab has been proposed to be used as add-on therapy in patients with allergic rhinitis and asthma and undergoing specific allergen immunotherapy (AIT). AIT is the only treatment that modifies the natural history of IgE-mediated diseases. This brief review summarizes the available evidence and controversies on the efficacy and safety of omalizumab combined with specific AIT (AU)

The efficacy of omalizumab treatment in patients with nonatopic severe asthma

Introduction: Nonatopic asthmatic patients generally have more severe clinical manifestations, frequently accompanied by chronic sinusitis and nasal polyps, with more limited therapeutic options as compared to atopic asthmatic patients. This has led to a search for novel thera-peutic approaches, including omalizumab, for nonatopic asthmatic patients who are not ade-quately controlled with current therapies.Materials and Methods: In this retrospective study undertaken between August 1, 2020, and December 31, 2021, at a tertiary allergy clinic, data from 61 patients with nonatopic asthma inadequately controlled with optimum therapy was examined.Results: A total of 61 patients with severe asthma were included in the study [Female: 48 (78.7%), male: 13 (21.3%, mean age: 49 (18–71) years]. The mean duration of asthma was 60 (18–160) months. A statistically significant increase in Forced expiratory volume (FEV1per sec-ond), forced vital capacity (FVC), and asthma control test (ACT) scores were found after 1 year of omalizumab treatment (p < 0.001, for all parameters). Omalizumab treatment was associated with a significant decrease in the number of asthma exacerbations, asthma-related hospitalizations, duration of hospitalizations, and several unplanned emergency room visits after 1 year (p < 0.001, for all parameters). A 1-year treatment with omalizumab led to signif-icant changes in eosinophil counts and serum IgE levels (p < 0.001 and < 0.001, respectively).Conclusion: In the severe atopic asthma patient group, omalizumab treatment provided similar clinical benefits to those observed in patients with severe atopic asthma, suggesting that it may be a useful therapeutic option in patients with nonatopic asthma who failed to benefit from treatments with steps 4 and 5 (AU)
