Background While acrylates are well-known skin sensitisers, they are not classified as respiratory sensitisers although several cases of acrylate-induced occupational asthma (OA) have been reported.Objectives The aim of this study was to evaluate the characteristics of acrylate-induced OA in a large series of cases and compare those with OA induced by other low-molecular-weight (LMW) agents.Methods Jobs and exposures, clinical and functional characteristics, and markers of airway Parts per billion QSAR:Quantitative structure activity relationship SIC:Specific inhalation challenge
Background Chronic cough (CC) represents a significant health burden. This study assessed the prevalence of CC (defined as per international guidelines as cough duration >8 weeks) in Spanish adults and compared characteristics between CC and non-CC cohorts. Methods CC cohorts were compiled using data from adult respondents to the 2020 Spanish cross-sectional online National Health and Wellness Survey (NHWS). Using propensity scores, respondents experiencing CC during their lifetime and the previous 12 months were matched 3:1 to respondents without CC and their health characteristics were compared. The number of Spanish adults affected with CC was estimated using weighted CC prevalence. Results CC during their lifetime or the previous 12 months was experienced by 579 (8.2%) and 389 (5.5%) of 7074 NHWS respondents, of whom 233 (38.5%) and 171 (44.0%), respectively, had physician-diagnosed CC. Based on weighted prevalence rates, lifetime and 12-month CC were estimated to affect ≈3.3 million and ≈2.2 million Spanish adults, respectively. Relative to the non-CC cohort, the 12-month CC cohort consistently demonstrated poorer health status, poorer mental health, greater healthcare utilization, and lower productivity at work and home. Conclusion This study contributes novel data regarding the prevalence of CC in Spain, suggests that CC is underdiagnosed, and reflects that CC and related comorbidities inflict a significant health burden in the affected population.
Purpose The aim of this study was to understand the perception of family physicians, pulmonologists, and allergists with respect to diagnostic tests performed on patients with chronic cough and treatments prescribed to patients with refractory or unexplained chronic cough. We also assessed how these health professionals perceived the effectiveness of these treatments. Methods An anonymous survey was distributed by the scientific societies SEPAR, SEAIC, SEMERGEN, semFYC, and SEMG. Respondents were asked how often they perform diagnostic tests and prescribe treatments (responses from 1 = never to 10 = always) and how they perceived the effectiveness of the drugs used (from 1 = not at all to 10 = very effective). The correlation between perceived effectiveness and frequency of prescription was analyzed. Results The respondents comprised 620 family physicians, 92 pulmonologists, and 62 allergists. The most frequently performed diagnostic tests were chest x-ray and, among pulmonologists and allergists, simple spirometry and bronchodilator tests. The most frequently prescribed drugs were bronchodilators (percentages scoring 8–10 for each specialty: 43.2%, 42.4%, and 56.5%; p = 0.127), inhaled corticosteroids (36.9%, 55.4%, and 54.8%; p < 0.001), and antitussives (family physicians, 33.4%). Regarding perceived effectiveness, only bronchodilators, inhaled or oral corticosteroids, and opioids obtained a median effectiveness score > 5 (between 6 and 7). Correlation coefficients (ρ2) suggested that approximately 45% of prescription was related to perceived effectiveness. Conclusion Although chronic cough is a common problem, diagnosis and treatment differ among specialists. The perceived effectiveness of drugs is generally low.
Purpose Chronic cough (cough that persists for ≥ 8 weeks) can cause a range of physical symptoms and psychosocial effects that significantly impair patients’ quality of life. Refractory chronic cough (RCC) and unexplained chronic cough (UCC) are challenging to diagnose and manage, with substantial economic implications for healthcare systems. Methods This retrospective multicenter non-interventional study aimed to characterize the profile and health resource consumption of patients with RCC or UCC who attended outpatient clinics at Spanish hospitals. Data were collected from medical records of patients with RCC or UCC for up to 3 years before study inclusion. Results The patient cohort (n = 196) was representative of the chronic cough population (77.6% female, mean age 58.5 years). Two-thirds of patients (n = 126) had RCC. The most frequently visited doctors were pulmonologists (93.4% of patients) and primary care physicians (78.6%), with a mean of 5 visits per patient over three years’ observation. The most common diagnostic tests were chest x-ray (83.7%) and spirometry with bronchodilation (77.0%). The most commonly prescribed treatments were proton pump inhibitors (79.6%) and respiratory medications (87.8%). Antibiotics were prescribed empirically to 56 (28.6%) patients. Differences between RCC or UCC groups related mainly to approaches used to manage cough-associated conditions (gastroesophageal reflux disease, asthma) in patients with RCC. Conclusion RCC and UCC are responsible for high health resource utilization in Spanish hospitals. Specific treatments targeting the pathological processes driving chronic cough may provide opportunities to reduce the associated burden for patients and healthcare systems.
