“Vespid Allergy Quality of Life Questionnaire (VQLQ)” has been used to assess psychological burden of disease. The aim of this study was to evaluate validity, reliability and responsiveness to interventions of the Turkish version. The Turkish language Questionnaire (VQLQ-T) was administered to 81 patients with bee allergy and 65 patients with vespid allergy from different groups to achieve cross-sectional validation. To establish longitudinal validity, the questionnaire was administered to 36 patients treated with venom immunotherapy. The cross-sectional validation in patients with vespid venom allergy showed a correlation coefficient of 0.97 (Cronbach α). Spearman’s correlation coefficient of the pretreatment VQLQ-T score with Expectation of Outcome (EoO) questionnaire score was 0.55 (p < 0.001). After treatment, correlation between VQLQ-T score and EoO score was 0.64 (p = 0.003) in these patients. The cross-sectional instrument validation for non-beekeepers with bee venom allergy yielded a correlation coefficient of 0.96 (Cronbach α). Spearman’s correlation coefficient between pretreatment VQLQ-T score and EoO score was 0.47 (p < 0.001) and after treatment, correlation between VQLQ-T score and EoO score was 0.78 (p = 0.008) in these patients. These findings indicate cross-sectional validity of VQLQ-T. In the longitudinal validation, there was a positive correlation between EoO and VQLQ-T with a correlation coefficient of 0.562 (p < 0.001). While mean (±SD) VQLQ-T score was 5.27 (±1.29) in pretreatment, it was 2.78 (±1.01) after treatment (p < 0.001). The correlation between the mean change in VQLQ-T score and the mean change in EoO score was 0.42 (p = 0.011). The Turkish version of VQLQ-T enables measurement of Quality of Life (QoL) in patients with either vespid or bee venom allergy. Furthermore, responsiveness of this instrument demonstrates the questionnaire’s ability to detect changes over time.

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.

Background and Objectives: Hereditary angioedema (HAE) is characterized by unpredictable skin and mucosal angioedema attacks. We aimed to find the frequency of sexual-activity-triggered attacks (STAs) and understand how the sexual life of HAE with C1-inhibitor deficiency (HAE-C1INH) patients is affected. Materials and Methods: Adult HAE-C1INH patients were included in this cross-sectional study, which started in March 2020. Demographic information, marriage properties, gender-specific sexual life characteristics, and the HAE-specific histories of the patients were collected. The Hospital Anxiety and Depression Scale (HADS) and the Turkish version of the New Sexual Satisfaction Scale (NSSS) were applied to all participants. Results: Among 42 symptomatic HAE patients, 33 (78.57%) had genital attacks and 17 (42.5%) had STAs. Ten (58.8%) had genital pain, tenderness, or swelling, and five (29.4%) had isolated abdominal and groin pain. Eight (47.1%) patients with STAs experienced a HAE attack during their first time engaging in sexual intercourse. Anxiety/depression scales, NSSS scores, and distribution of other HAE attack localizations were similar in patients with and without STAs, and no gender differences were observed. Compared to the patients without STAs, the ratio of patients who stated that their sexual lives were negatively affected and that they lost their sexual desire was higher in patients with STAs. Conclusions: Genital or abdominal attacks triggered by sexual activity may be more common than thought. Sexual activity should also be questioned for evaluating attack triggers. There is a possibility of triggering an attack with the first and ongoing sexual intercourse, and patients should be informed to keep their attack treatment medications ready in advance.

Background: β-Lactams are the most widely used antibiotic family in the world. Nevertheless, they also stand out as the primary culprits for inducing drug hypersensitivity reactions (HSR). Methods: Between May 2018 and March 2023, patients with suspected HSRs to β-lactams, who underwent skin tests (ST), were retrospectively screened. The determinants of allergenic penicillin (DAP) tests, which include penicillin minor and major determinants, clavulanic acid, and amoxicillin, along with ampicillin, sulbactam, the identified culprit drugs, and alternative cephalosporins, which include cefuroxime, ceftriaxone prick and/or intradermal tests, were administered. The analysis focused on identifying positive ST results and determining the true HSRs rates in this patient cohort. Results: Of the 147 patients, 78.9% (n = 116) were women and the median (minimum-maximum) age was 41 years (18‐71 years). Mild HSRs (grades 1‐2) were observed in 72.78% (n = 107), whereas 24.4% (n = 36) had severe reactions (grades 3‐4) and 2.7% (n = 4) had an unknown grade. Of the patients, 64% (n = 94) experienced HSRs within the first hour after the last dose of the identified culprit drug. The overall positivity rate for all STs was 26.5% (n = 39). ST positivity rates were notably higher in individuals who had experienced HSRs within the past 6 months (p = 0.02) and those with severe anaphylaxis (p < 0.001). Conclusion: β-Lactam ST positivity is higher, especially in those with grades 3‐4 reactions and consulted a physician within the first 6 months after their HSRs.
