Background: Sting challenge with a live insect remains the best test for proving the efficacy of immunotherapy in Hymenoptera allergy., Objective: We studied the impact of tolerated sting challenge on quality of life., Patients and Methods: In this prospective study, data were collected via self-report questionnaires completed by consenting patients with Hymenoptera venom allergy on venom immunotherapy before and after a sting challenge., Results: The study population comprised 100 adult patients (82 with yellow jacket allergy and 18 with honeybee allergy) who participated between September 2009 and November 2010. After the sting challenge, the score on the Vespid Allergy Quality of Life Questionnaire revealed a statistically significant improvement (mean [SD] change, 0.73 [0.98]; P < .0001; 95% CI, 0.52-0.94). This improvement was independent of the patients' gender and age and the severity of the initial anaphylactic reaction. A statistically significant improvement was documented in 2 subgroups of the Short Form 36 Health Survey (physical functioning, mean change, -5.78 [25.23]; P = .038; 95% CI, -11.22 to -0.34; vitality, mean change -4.29 [12.49]; P =.002; 95% CI, -7.02 to -1.57)., Conclusions: Sting challenge results in a significant improvement in disease-specific quality of life and subgroups of general quality of life in patients allergic to Hymenoptera venom receiving established venom immunotherapy.

Background: The use of selective cyclooxygenase (COX) 2 inhibitors as an alternative to aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) has been suggested for patients with aspirin-exacerbated respiratory disease (AERD)., Objective: To evaluate tolerability to etoricoxib, a second-generation COX-2 inhibitor with high in vitro selectivity for COX-2 in patients with AERD., Methods: We conducted a retrospective review of patients with suspected aspirin intolerance seen between October 2007 and April 2012. Single-blind, placebo-controlled oral challenges with increasing doses of aspirin and etoricoxib were performed on 3 different days., Results: Of 262 patients with suspected aspirin intolerance, 248 underwent challenge testing with aspirin and 122 (49.2%) showed positive test results. In 104 of these aspirin-sensitive patients, etoricoxib was tested as an alternative drug and was tolerated in all but 3 (2.9%), who developed a positive asthmatic reaction., Conclusions: The highly selective COX-2 inhibitor etoricoxib was tolerated in most but not all patients tested. An oral provocation test is therefore recommended before prescribing etoricoxib for patients with AERD.
