RESUMO
BACKGROUND: Food-induced anaphylaxis (FIA) is a major public health problem resulting in serious clinical complications, emergency department visits, hospitalization, and death. OBJECTIVE: The objectives of this investigation were to assess the epidemiology and the trends in hospitalizations because of FIA in Spain between 2016 and 2021. METHODS: An observational descriptive study was conducted using data from the Spanish National hospital discharge database. Information is coded based on the International Classification of Diseases, Tenth Revision. The study population was analyzed by sex and age group and according to food triggers, clinical characteristics, admission to the intensive care unit (ICU), severity, and in-hospital mortality (IHM). The annual incidence of hospitalizations because of FIA per 100,000 person-years was estimated and analyzed using Poisson regression models. Multivariable logistic regression models were constructed to identify which variables were associated with severe FIA. RESULTS: A total of 2161 hospital admissions for FIA in were recorded in Spain from 2016 to 2021. The overall incidence rate was 0.77 cases per 100,000 person-years. The highest incidence was found in the <15-year age group (3.68), with lower figures among those aged 15-59 years (0.25) and ≥60 years (0.29). Poisson regression showed a significant increase in incidence from 2016 to 2021 only among children (3.78 per 100,000 vs. 5.02 per 100,000 person-years; p=.047). The most frequent food triggers were ""Milk and dairy products" (419/2161, 19.4% of cases) and "Peanuts and tree nuts and seeds" (409/2161, 18.9%). Overall, 256 of 2161 (11.9%) patients hospitalized because of FIA required admission to the ICU, and 11 patients (0.5%) died in hospital. Among children, the most severe cases of FIA appeared in patients aged 0 to 4 years (40/99, 40.4%). Among adults, 69.4% (111/160) of cases occurred in those aged 15 to 59 years. Multivariable logistic regression showed the variables associated with severe FIA to be age 15-59 years (OR, 5.1; 95% CI, 3.11-8.36), age ≥60 years (OR, 3.87; 95% CI, 1.99-7.53), and asthma. CONCLUSIONS: In Spain, the incidence of hospitalization because of FIA increased slightly, although the only significant increase was among children. Even if IHM remains low and stable, the proportion of severe cases is high and has not improved from 2016 to 2021, with older age and asthma being risk factors for severity. Surveillance must be improved, and preventive strategies implemented to reduce the burden of FIA.
RESUMO
Background/Objectives: To analyze changes in the prevalence of atrial fibrillation (AF) in patients hospitalized for acute exacerbation of chronic obstructive pulmonary disease (AE-COPD); to evaluate hospital outcomes according to AF status, assessing sex differences; to identify factors associated with AF presence; and to analyze variables associated with in-hospital mortality (IHM) in AE-COPD patients with AF. Methods: We used data from the Registry of Specialized Care Activity-Basic Minimum Data Set (RAE-CMBD) to select patients aged ≥40 years with COPD in Spain (2016-2021). We stratified the study population according to AF presence and sex. The propensity score matching (PSM) methodology was employed to create comparable groups based on age, admission year, and comorbidities at the time of hospitalization. Results: We identified 399,196 hospitalizations that met the inclusion criteria. Among them, 20.58% had AF. The prevalence of AF rose from 2016 to 2021 (18.26% to 20.95%), though the increase was only significant in men. The median length of hospital stay (LOHS) and IHM were significantly higher in patients with AF than in those without AF. After PSM, IHM remained significantly higher for man and women with AF. Older age, male sex, and several comorbidities were factors associated with AF. Additionally, older age, male sex, different comorbidities including COVID-19, hospitalization in the year 2020, mechanical ventilation, and intensive care unit (ICU) admission were associated with higher IHM in patients with AE-COPD and AF. Conclusions: AF prevalence was high in patients hospitalized for AE-COPD, was higher in men than in women, and increased over time. AF presence was associated with worse outcomes. The variables associated with IHM in hospitalized AE-COPD patients with AF were older age, male sex, different comorbidities including COVID-19 presence, hospitalization in the year 2020, need of mechanical ventilation, and ICU admission.
