Background and Objectives: Real-life data on the efficacy of biologic agents (BAs) on asthma-comorbid CRSwNP are needed. Our primary goal is to investigate the effects of BAs on CRSwNP symptoms, as well as endoscopic and tomography scores. Our secondary goal is to show a reduction in the frequency of acute sinusitis exacerbations and the need for surgery. Materials and Methods: We conducted a multicenter, retrospective, real-life study. We screened the patients with asthma-comorbid CRSwNP treated with omalizumab or mepolizumab. A total of 69 patients (40 F/29 M; omalizumab n = 55, mepolizumab n = 14) were enrolled. We compared the visual analog scale (VAS), sinonasal outcome test-22 (SNOT-22), nasal congestion score (NCS), Lund–Mackay computed tomography score (LMS), and total endoscopic polyp scores (TPS) before and after BAs. We evaluated the endoscopic sinus surgery (ESS) and acute exacerbations of chronic rhinosinusitis (AECRS) frequencies separately, according to the BAs. Results: The overall median (min–max) age was 43 (21–69) years. The median (min–max) of biologic therapy duration was 35 (4–113) months for omalizumab and 13.5 (6–32) for mepolizumab. Significant improvements were seen in VAS, SNOT-22, and NCS with omalizumab and mepolizumab. A significant decrease was observed in TPS with omalizumab [95% CI: 0–4] (p < 0.001), but not with mepolizumab [95% CI: −0.5–2] (p = 0.335). The frequency of ESS and AECRS were significantly reduced with omalizumab [95% CI: 2–3] (p < 0.001) and [95% CI: 2–5] (p < 0.001); and mepolizumab [95% CI: 0–2] (p = 0.002) and [95% CI: 2–8.5] (p < 0.001), respectively. There was no significant difference in LMS with either of the BAs. Conclusions: Omalizumab and mepolizumab can provide a significant improvement in the sinonasal symptom scores. BAs are promising agents for CRSwNP patients with frequent exacerbations and multiple surgeries.

Background: New technologies have resulted in dramatic shifts in the field of medicine, and it stands to reason that metaverse will also affect the practice of allergy and immunology. This study aimed to determine the attitudes of allergists and raise awareness about metaverse applications in allergy and immunology. Methods: A nationwide survey-based study was conducted in Turkey. First, a 28-item questionnaire was developed and sent to Turkish allergists. After completing the first questionnaire, the participants were asked to watch a 5-min informative video about the metaverse. Lastly, a second survey was conducted to evaluate the changes in the views of the participants. Results: A total of 148 allergy doctors in Turkey participated in the survey. After watching a video containing updated information about the metaverse, there was a significant increase in the importance that participants attributed to the use of virtual reality and augmented reality applications in the field of immunology and allergy (P < 0.05). Additionally, there was a significant increase in the percentage of participants who thought that Metaverse applications could be integrated into the existing system and said that this possibility excited them (P < 0.05). There was also a significant increase in the percentage of participants who thought this innovative technology could be helpful in patient examination, student and physician education, allergy testing, and patient education (P < 0.05). Conclusions: Our results demonstrate that providing information to professionals working in the field can positively influence physicians’ views on the potential of the metaverse, which is a valuable tool in the field of immunology and allergy.

Purpose Inborn Errors of Immunity (IEI) often lead to recurrent infections, immune dysregulation, and an increased risk of malignancies. Due to the heterogeneity in IEI presentations, personalized monitoring is essential for early detection of non-infectious complications. This study aims to document the characteristics and prevalence of malignancies in IEI patients. Methods A retrospective review of 355 patients diagnosed with IEI at the Adult Allergy and Immunology Clinic of Ege University was conducted. Data on demographics, clinical presentations, laboratory results, and immunological and genetic profiles of patients with malignancies were analyzed. Results A total of 40 patients with neoplasia (F/M: 18/22; median age: 51.58 years, range: 18–91) were evaluated. The median ages at IEI symptom onset, diagnosis, and neoplasm diagnosis were 16.5, 45, and 39.5 years, respectively. Malignancy was diagnosed in 60% of patients before IEI, with referrals for low immunoglobulin levels and/or severe infections, and for a genetic profile suggestive of immunodeficiency. The prevalence of malignancy in the overall cohort was 10.42% (37/355), while it was significantly higher in the common variable immunodeficiency (CVID) subgroup, reaching 20.44% (28/137). Lymphoma was the most common malignancy at 45.9%, primarily non-Hodgkin lymphoma (NHL) at 40.5%, with diffuse large B-cell lymphoma (DLBCL) as a key subtype; carcinomas were the second most common at 35.1%. Hematologic malignancies were significantly more frequent among patients with CVID (90.5%), whereas non-hematologic malignancies predominated in the non-CVID group (77.8%) (p = 0.024). Lymphoproliferation was more common in hematologic malignancies (85.7%) compared to non-hematologic malignancies (25.0%) (p < 0.001). Genetic variants were identified in 61% of cases, with 37% classified as pathogenic or likely pathogenic, including variants in TNFRSF13B/TACI, CCDC40, PLCG2, ATM, CARD11, CHEK2, CNV, COPB1, HPS5, LYST, MAPK8IP1, NBS1, NF1, NFKBIA, PI4KA, POLE, SPI1, and TAP2. Conclusions Findings confirm that NHL, particularly DLBCL, is the most prevalent malignancy in this cohort. Given the link between malignancies and underlying IEI, immunologic evaluation is recommended, particularly for NHL patients. The observed predominance of hematologic malignancies among CVID patients and the association with lymphoproliferation further emphasize the need for heightened malignancy surveillance and early immunologic workup in this subgroup. Further research on biomarkers for malignancy prediction in IEI is warranted.

Background/Objectives: Immediate-type hypersensitivity reactions (HSRs) to proton pump inhibitors (PPIs) represent a clinically relevant adverse drug reaction and pose diagnostic and management challenges, including variable cross-reactivity (CR). Drug provocation testing (DPT) is the diagnostic gold standard, but real-life use after testing remains uncertain. This study aimed to describe clinical features, diagnostic outcomes, CR profiles, and real-life PPI use in patients with immediate-type PPI hypersensitivity. Methods: Single-center ambispective study of 40 patients evaluated for immediate-type PPI HSRs (2014–2023). Index reactions, culprit PPI, and skin test/DPT results were recorded retrospectively. Patients tolerating an alternative PPI on DPT were followed prospectively; real-life tolerance and use were assessed by structured telephone interview. Results: Among 40 patients (87.5% female; mean age 48 years), lansoprazole was the most frequent culprit (50%); anaphylaxis occurred in 65%. Skin tests were positive in 25% (n = 9), and a shorter interval from reaction to testing was associated with positivity (p = 0.025). CR was detected in 25% (n = 10), most often between lansoprazole and pantoprazole. All 29 patients undergoing DPT tolerated at least one alternative PPI. In real-life follow-up (n = 27), 11 (40.7%) restarted PPIs without recurrence; 1 (3.7%) developed a mild cutaneous reaction despite negative testing. Fifteen (55.6%) did not restart therapy; 4 (14.8%) cited drug-related anxiety or physician-advised avoidance. Conclusions: In immediate-type PPI hypersensitivity, skin test sensitivity appears time-dependent, supporting early evaluation. DPT identifies safe alternatives, yet behavioral and clinician-related barriers limit real-life implementation; addressing these barriers is essential to optimize PPI allergy management.
