RESUMEN
BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most prevalent drugs inducing hypersensitivity reactions. The aim of this analysis was to estimate the prevalence of NSAID-induced respiratory symptoms in population across Europe and to assess its association with upper and lower respiratory tract disorders. METHODS: The GA2 LEN survey was conducted in 22 centers in 15 European countries. Each of 19 centers selected random samples of 5000 adults aged 15-74 from their general population, and in three centers (Athens, Munich, Oslo), a younger population was sampled. Questionnaires including questions about age, gender, presence of symptoms of asthma, allergic rhinitis, chronic rhinosinusitis, smoking status, and history of NSAID-induced hypersensitivity reactions were sent to participants by mail. Totally, 62 737 participants completed the questionnaires. RESULTS: The mean prevalence of NSAID-induced dyspnea was 1.9% and was highest in the three Polish centers [Katowice (4.9%), Krakow (4.8%), and Lodz (4.4%)] and lowest in Skopje, (0.9%), Amsterdam (1.1%), and Umea (1.2%). In multivariate analysis, the prevalence of respiratory reactions to NSAIDs was higher in participants with chronic rhinosinusitis symptoms (Odds Ratio 2.12; 95%CI 1.78-2.74), asthma symptoms in last 12 months (2.7; 2.18-3.35), hospitalization due to asthma (1.53; 1.22-1.99), and adults vs children (1.53; 1.24-1.89), but was not associated with allergic rhinitis. CONCLUSION: Our study documented significant variation between European countries in the prevalence of NSAID-induced respiratory hypersensitivity reactions, and association with chronic airway diseases, but also with environmental factors.

BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs)-exacerbated respiratory disease (N-ERD) complicates the clinical course of chronic rhinosinusitis with nasal polyps (CRSwNP) and severe asthma. We aimed to determine the detection rate of NERD in patients with CRSwNP, asthma, and history of NSAID intolerance using nasal challenge with acetylsalicylic acid (ASA) and the relationship between the severities of response to ASA challenges and the grade of N-ERD. MATERIALS AND METHODS: Three groups of patients were included: CRSwNP with asthma and clinical history of analgesics intolerance (CRSwNP-AAI n = 18), CRSwNP with asthma but without a clinical history of analgesics intolerance (CRSwNP-A n = 20), and CRSwNP without asthma or analgesics intolerance (n = 18). All subjects were challenged nasally with 16 mg ASA and monitored with active anterior rhinomanometry. Rhinological (nasal polyp score), pulmonary (spirometry, Asthma Control Test (ACT), and asthma treatment), and psychometric questionnaire scores were recorded and correlated with rhinomanometric data following nasal challenges (flow depressions and symptom scores). RESULTS: Nasal ASA challenge detected N-ERD in 96.7% of CRSwNP-AAI patients and 45% of CRSwNP-A patients. No N-ERD was seen in the CRSwNP group. The control grade of asthma measured with ACT scores was significantly lower in the groups CRSwNP-AAI (MV 18.22) and CRSwNP-A (MV 19.75) when compared to the CRSwNP group (MV 24.39) (p = 0.000). In the CRSwNP-AAI group, 11 patients had uncontrolled asthma (61%), and in the CRSwNP-A group, 9 patients had uncontrolled asthma (45%). No correlation was found between rhinology and pulmonary parameters, nasal symptoms, and the severity of nasal ASA challenges. Specific reactions were detectable under the therapy of prednisolone and omalizumab. CONCLUSION: N-ERD might not always be detected by screening a patient's medical history. Nasal ASA challenges are recommended in patients with CRSwNP and asthma. The nasal challenge with ASA positively confirms the N-ERD diagnosis. Moreover, N-ERD is a differential diagnosis in patients with severe asthma with the need for prednisolone or omalizumab therapy. The severity of the reaction to the ASA challenge in controlled and uncontrolled asthma patients is independent of the grade of N-ERD.â©.

Nonsteroidal anti-inflammatory drugs are the medications most frequently involved in hypersensitivity reactions to drugs. These can be induced by specific immunological and nonimmunological mechanisms, being the latter the most frequent. The nonimmunological mechanism is related to an imbalance of inflammatory mediators, which is aggravated by the cyclooxygenase inhibition. Genetic studies suggest that multiples genes and additional mechanisms might be involved. The proposals of this review is summarize the contribution of variations in genes involved in the arachidonic acid, inflammatory and immune pathways as well as the recent genome-wide association studies findings related to cross-intolerant nonsteroidal anti-inflammatory drugs hypersensitivity reactions. In addition, using integration of different genetic studies, we propose new target genes. This will help to understand the underlying mechanism of these reactions.

BACKGROUND: According to the Global Initiative for Asthma (GINA), the levels of asthma symptom control can be divided into controlled, partially controlled and uncontrolled asthma. Optional therapy for non-steroidal anti-inflammatory drugs (NSAIDs)-hypersensitive asthmatics uses aspirin desensitization, but until now, this therapy is not established in difficult to treat cases. The aim of this study was to evaluate the efficacy of aspirin desensitization in patients with poorly controlled asthma. METHODS: Patients with poorly controlled asthma, NDAIDs hypersensitivity and aspirin desensitization were included in the retrospective study. The data were compared to those obtained from patients with controlled asthma and aspirin therapy. Lung function, levels of asthma symptom control, asthma medication, the size of nasal polyps (NP) and smell function were evaluated over 18 months. RESULTS: Thirty-two patients were included in the study (uncontrolled/partially controlled asthma n=12; controlled asthma n=20). After 18 months of follow-up, the patients with poorly controlled asthma had significantly increased forced expiratory volume in 1s (FEV1) values, as compared to the baseline (66-82%; p=0.02), the levels of asthma control improved significantly (p<0.01). The asthma medication was reduced. In the group of controlled asthma the FEV1 values did not increase significantly (91.9-92.4%; p>0.05) and the asthma medication was constant. In relation to nasal parameters the sense of smell improved significantly in both groups, NP-scores did not differ significantly. CONCLUSIONS: Patients with a poorly controlled asthma and NSAIDs hypersensitivity profit from an add-on aspirin therapy.
RESUMEN
We introduce the reader to systems biology, using adverse drug reactions (ADRs), specifically hypersensitivity reactions to multiple non-steroidal anti-inflammatory drugs (NSAIDs), as a model. To disentangle the different processes that contribute to these reactions - from drug intake to the appearance of symptoms - it will be necessary to create high-throughput datasets. Just as crucial will be the use of systems biology to integrate and make sense of them. We review previous work using systems biology to study related pathologies such as asthma/allergy, and NSAID metabolism. We show examples of their application to NSAIDs-hypersensitivity using current datasets. We describe breakthroughs in high-throughput technology and speculate on their use to improve our understanding of this and other drug-induced pathologies.
