Abstract
The frequency of food allergies varies between 2% and 10%, depending on characteristics including age, region, race, and method of diagnosis self-reported by patients or oral food challenges (OFCs). The most common allergies reported are tree nuts (1.2%), milk (1.9%), peanuts (2.2%), and shellfish (1.3%). Omalizumab injection has now been approved by the FDA for the treatment of immunoglobulin E-mediated food allergies in specific adults and children aged one year or older. This medication reduces the risk of allergic reactions (Type I), which can include anaphylaxis, when an individual accidentally encounters one or more food allergens. Omalizumab functions by binding to IgE and altering IgE-mediated pathways, which lessens IgE's capacity to cause allergic reactions. Promising outcomes from clinical trials and case studies include lowered anaphylactic risk and enhanced tolerance to allergens. Omalizumab, however, may have adverse effects; thus, close observation is required. Overall, this review sheds light on the efficacy, safety, and clinical implications of omalizumab, highlighting its potential as a useful intervention for IgE-mediated food allergies.

Yu J, Yan B, Shen S, Wang Y, Li Y, Cao F, Xiong W, Piao Y, Hu C, Sun Y, Zhang L, Wang C. IgE directly affects eosinophil migration in chronic rhinosinusitis with nasal polyps through CCR3 and predicts the efficacy of omalizumab. J Allergy Clin Immunol 2024; 153:447-460.e9. [PMID: 37922997 DOI: 10.1016/j.jaci.2023.09.041] [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: 11/13/2022] [Revised: 07/28/2023] [Accepted: 09/25/2023] [Indexed: 11/07/2023]
Abstract
BACKGROUND Whether IgE affects eosinophil migration in chronic rhinosinusitis with nasal polyps (CRSwNP) remains largely unclear. Moreover, our understanding of local IgE, eosinophils, and omalizumab efficacy in CRSwNP remains limited. OBJECTIVE We investigated whether IgE acts directly on eosinophils and determined its role in omalizumab therapy. METHODS Eosinophils and their surface receptors were detected by hematoxylin and eosin staining and flow cytometry. IgE and its receptors, eosinophil peroxidase (EPX), eosinophilic cationic protein, and CCR3 were detected by immunohistochemistry and immunofluorescence. Functional analyses were performed on blood eosinophils and polyp tissues. Logistic regression was performed to screen for risk factors. Receiver operating characteristic curve was generated to evaluate the accuracy. RESULTS Both FcεRI and CD23 were expressed on eosinophils. The expression of FcεRI and CD23 on eosinophil in nasal polyp tissue was higher than in peripheral blood (both P < .001). IgE and EPX colocalized in CRSwNP. IgE directly promoted eosinophil migration by upregulating CCR3 in CRSwNP but not in healthy controls. Omalizumab and lumiliximab were found to be effective in restraining this migration, indicating CD23 was involved in IgE-induced eosinophil migration. Both IgE+ and EPX+ cells were significantly reduced after omalizumab treatment in those who experienced response (IgE+ cells, P = .001; EPX+ cells, P = .016) but not in those with no response (IgE+ cells, P = .060; EPX+ cells, P = .151). Baseline IgE+ cell levels were higher in those with response compared to those without response (P = .024). The baseline local IgE+ cell count predicted omalizumab efficacy with an accuracy of 0.811. CONCLUSIONS IgE directly promotes eosinophil migration, and baseline local IgE+ cell counts are predictive of omalizumab efficacy in CRSwNP.

Omalizumab improves sleep and health status for patients with chronic rhinosinusitis with nasal polyps: An analysis of randomized clinical trials. Int Forum Allergy Rhinol 2024. [PMID: 38197558 DOI: 10.1002/alr.23322] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 12/04/2023] [Accepted: 12/28/2023] [Indexed: 01/11/2024]
Abstract
BACKGROUND Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) have high incidence of sleep impairment. We evaluated the impact of omalizumab treatment on sleep characteristics and associated health status in patients with CRSwNP. METHODS Prespecified exploratory analysis assessed outcomes from patients included in the POLYP 1 and POLYP 2 phase 3 clinical trials and the open-label extension. Sleep was assessed by the sleep domain of the Sino-Nasal Outcome Test-22 (SNOT-22; MCID > 4 in patients with CRS) and the Medical Outcomes Study Sleep Scale (MOS-Sleep). Health status was assessed by Healthy Days Core Module (HDCM) and sinonasal-specific Patient Global Impression of Change (PGIC). RESULTS Omalizumab improved sleep as assessed by the SNOT-22 sleep domain. At week 24, adjusted mean (95%CI) SNOT-22 sleep scores had reduced from baseline by -8.5 (-9.9 to -7.1) with omalizumab versus -2.7 (-4.1 to -1.3) with placebo. At week 52 (all patents on OMA), adjusted mean (95%CI) SNOT-22 sleep scores had reduced from baseline by -10.1 (-11.4 to -8.7) with omalizumab. Improvements were observed in all eight items of the SNOT-22 sleep domain: difficulty falling asleep, fatigue, frustration/restlessness/irritability, lack good night's sleep, reduced concentration, reduced productivity, wake up tired, and wake up at night. In addition, omalizumab improved six of eight sleep outcomes on the MOS-Sleep scale. There were concurrent improvements in HDCM and PGIC. CONCLUSION Omalizumab improved sleep and self-reported health status in patients with CRSwNP. This contributes to evidence that omalizumab provides value for patients beyond the reduction of sinonasal symptoms.

Abstract
PURPOSE OF REVIEW Despite molecular underlying advances, limited and divergent data on monoclonal antibodies (mAb) therapy in chronic rhinosinusitis with nasal polyps (CRSwNP) make further analysis necessary. The objective of this study is to evaluate the effect of omalizumab as an adjunct to endoscopic sinus surgery (ESS) on the treatment of CRSwNP under real-life conditions. RECENT FINDINGS Since the introduction of omalizumab, as the first biologic agent for the treatment of diseases such as severe allergic asthma, different studies have demonstrated an effect of omalizumab on CRSwNP, with significant improvements in sinonasal symptoms and endoscopic scores. The high efficacy derived from mAb therapy and the need for ESS prior to mAb recommended by guidelines, has led to compare both therapeutic alternatives, finding discrepancies in their effect on quality of life (QoL) and complementary tests outcomes. Patients with moderate-to-severe asthma with clinical criteria for omalizumab indication, and coexistent CRSwNP disease, were selected for a non-randomized interventional retrospective study into four treatment subgroups. Measures were analyzed and compared between groups and over time at the baseline, 16 weeks and 1 and 2 years after treatment. Omalizumab treatment in patients with previous ESS exhibited an earlier and more pronounced improvement in QoL, symptoms scale and endoscopic findings (nasal polyp score and the bilateral modified Lund-Kennedy) as early from week 16, which improvement persisted for 2 years. A greater mean improvement of 33.4 ± 6.5 (95% CI: 20.3-46.4; p < 0.001) points in sinonasal outcome test 22 (SNOT-22) was associated with ESS at week 16, against omalizumab effect (17.8 ± 7.6 [95% CI: 2.6-33.0]; p = 0.023). At year 2, an improvement in SNOT-22 of 62.6 ± 8.9 (95% CI: 48.4-84.1; p < 0.001) points was exclusively associated with omalizumab. Clinical evidence of the effect of omalizumab added to ESS treatment is provided in this study in the short- and long-term.

Abstract
INTRODUCTION In recent years, endotypes of chronic rhinosinusitis (CRS) based on the underlying immune mechanisms provided a better understanding of this heterogeneous disease and are frequently applied in diagnosis and treatment. AREAS COVERED In this manuscript, we aim to review novel treatment approaches for this often uncontrolled disease and highlight endotype-driven medical algorithms that could be beneficial in daily clinical practice. EXPERT OPINION With the development of endotyping and the mucosal inflammatory concept, several type 2-targeted biologics and surgical options are nowadays available for treating CRS. However, a better understanding based on clinical trials and real-life experience in daily practice is needed to optimize patient selection, biological drug selection, treatment duration, prediction, and long-term follow-up strategies. Indirect comparison analysis suggested that dupilumab might be the most effective biologic for treating CRS with nasal polyps, but the role and timing of surgery remain unclear. More real-life studies and comparative trials are needed for the optimal integration of biologics into clinical pathways in combination with established treatment approaches such as nasal and oral glucocorticosteroids and adequate surgery to provide long-term perspectives.

Abstract
BACKGROUND Allergic rhinitis (AR) and chronic rhinosinusitis (CRS) are two prevalent nasal diseases where both type 2 inflammation and immunoglobulin E (IgE) may play important roles. Although they can exist independently or comorbidly, subtle but important differences exist in immunopathogenesis. OBJECTIVE To summarize current knowledge of pathophysiological roles of B lineage cells and IgE in AR and CRS with nasal polyps (CRSwNP). METHODS Searched PubMed database, reviewed AR and CRSwNP-related literature, and discussed disease diagnosis, comorbidity, epidemiology, pathophysiology, and treatment. Similarities and differences in B-cell biology and IgE are compared in the 2 conditions. RESULTS Both AR and CRSwNP have evidence for pathological type 2 inflammation, B-cell activation and differentiation, and IgE production. However, distinctions exist in the clinical and serological profiles at diagnosis, as well as treatments utilized. B-cell activation in AR may more frequently be regulated in the germinal center of lymphoid follicles, whereas CRSwNP may occur via extrafollicular pathways although controversies remain in these initial activating events. Oligoclonal and antigen-specific IgE maybe predominate in AR, but polyclonal and antigen-nonspecific IgE may predominate in CRSwNP. Omalizumab has been shown efficacious in treating both AR and CRSwNP in multiple clinical trials but is the only Food and Drug Administration-approved anti-IgE biologic to treat CRSwNP or allergic asthma. Staphylococcus aureus frequently colonizes the nasal airway and has the ability to activate type two responses including B-cell responses although the extent to which it modulates AR and CRSwNP disease severity is being investigated. CONCLUSION This review highlights current knowledge of the roles of B cells and IgE in the pathogenesis of AR and CRSwNP and a small comparison between the 2 diseases. More systemic studies should be done to elevate the understanding of these diseases and their treatment.
