Background and Objectives: Drug provocation tests (DPTs) diagnose drug hypersensitivity reactions (DHRs) and identify safe alternatives. DHRs contribute to patient anxiety. The aim of this study was to evaluate anxiety and hopelessness levels before and after DPT and to examine patients’ avoidance characteristics of the tested drugs. Materials and Methods: Patients undergoing DPT were included. The State–Trait Anxiety Inventory (STAI) assessed anxiety, and the Beck Hopelessness Scale measured hopelessness. Demographic and clinical data, pre- and post-DPT scores, the status of using the medication provided after DPT, and the reason for not using it were analyzed. Results: Seventy-nine patients (60 female, 75.9%) participated. Patients’ Beck Hopelessness Scale, STAI–State, and STAI–Trait scores decreased significantly after the DPT compared to the initial scores. Among the patients who developed a reaction during the drug provocation test, the rate of those whose scale scores increased was significantly higher than the rate of those who did not develop a reaction. A total of 42 patients (53.2%) did not use the alternative safe drug. Of these, six (14.3%) reported that their reluctance stemmed from a fear of experiencing a reaction similar to their initial adverse event. Patients with concomitant allergic diseases were less likely to use alternative safe drugs. Conclusions: DPT reduces long-term anxiety and hopelessness. However, one in seven patients avoids the prescribed safe drug due to fear of recurrence. Effective communication, especially with patients who have allergic conditions or experience a reaction during DPT, and psychological support may improve adherence to the tested medication.

Real-life studies are needed to evaluate the clinical outcomes of add-on tiotropium therapy in patients with asthma. The effects of adding tiotropium bromide to the treatment of asthmatic patients on pulmonary functions and asthma control using real-life data. In a retrospective study, spirometric measures and asthma control states were compared before and one year after of tiotropium treatment in asthmatic adults whose disease was not adequately controlled with a combination of inhaled corticosteroids and long-acting β2-agonists. One year after tiotropium treatment, mean FEV1, FEV1%, and FEV1/FVC ratio increased significantly compared to pretreatment values. Among 32 patients added tiotropium due to symptomatic asthma, 28 (87.5%) patients achieved well-controlled (ACT ≥ 20) end of the year and GINA treatment step-down in 4 (12.5%) patients. Monoclonal antibody therapies (mepolizumab or omalizumab) were initiated in 9 patients (28.1%). FEV1 values and FEV1/FVC ratios showed a statistically significant improvement from baseline measurements obtained prior to the initiation of tiotropium therapy, independent of monoclonal antibody use (p < 0.001 for each). The mean age of these patients was 48.78 ± 11.64 (range: 28 - 81) years, and 25 (78.1%) of them were female. Tiotropium bromide is an effective and reliable add-on therapy for symptomatic asthma when combined with ICS plus LABA, also leads to improvements in respiratory function and asthma control.

Aims: This study aims to define characteristics of hypersensitivity reactions with etoposide, and outcomes of desensitizations in immediate-type hypersensitivity rections Methods: This is a retrospective observational study of patients who had hypersensitivity reactions with etoposide from January 2019 to December 2023. Results: A total of 39 patients with lung cancer were included in the study. Ten (25.6%) patients had known other drug allergies and three (7.7%) patients had previous chemotherapeutic hypersensitivity two with paclitaxel and one with docetaxel. Most of the initial hypersensitivities were in the first or second cycle (n=29, 74.4%). Ten (25.4%) patients had hypersensitivity reactions at the first application of etoposide. Thirty (76.9%) patients had immediate-type hypersensitivity reactions. There was no significant difference in terms of patient and initial hypersensitivity characteristics between patients who had immediate or non-immediate type hypersensitivity reactions. Of the 30 patients with immediate-type hypersensitivity reactions, initial reaction was mild in 16 (53.3%) and moderate in 14 (46.7%) patients. Most common symptoms were erythema in 29 (96.7%), dyspnea in 13 (43.3%), chest tightness in 8 (26.7%), discomfortness in 7 (23.3%), and hypertension in 6 (20%). Skin tests were negative in five patients who underwent skin testing. A total of 98 desensitization courses were performed in 27 patients and 3 (11.1%) patients had breakthrough reactions. Conclusion: Most of the hypersensitivity reactions to etoposide are immediate-type and not severe. Desensitization is an effective and safe procedure to manage these reactions. Further research is needed to elucidate the mechanisms of hypersensitivity reactions.
