Background The efficacy of mepolizumab is well documented in severe eosinophilic asthma (SEA), although the stringent selection criteria adopted by SEA clinical trials limits the generalizability of results. Objective Our study evaluated the effectiveness and safety of mepolizumab in patients with SEA in Spain. The primary efficacy endpoint was the change in the rate of clinically significant asthma exacerbations 12 months after starting mepolizumab compared to the baseline rate in the 12 months prior to treatment. Patients were stratified by baseline blood eosinophil counts. Methods We conducted a multicentric observational cohort study of SEA patients treated with mepolizumab across 24 specialized hospital asthma units in Spain. Severe exacerbation rate, lung function, oral corticosteroid use (OCS) and asthma control test (ACT) were retrospectively collected and compared during the 12-month pre-and post-mepolizumab treatment. Adverse events were also investigated. Results A total of 318 patients with SEA were included (mean age: 56.6 years, 69.2% female). Exacerbation rates decreased by 77.5%, and 50.6% of patients did not suffer any exacerbations during the 12 months of treatment. The difference in forced expiratory volume in 1 s (FEV1) pre-and post-bronchodilator after starting mepolizumab was 0.21 (0.46) L (95% CI 0.14-0.27) (p < 0.001). Exacerbations and lung function significantly improved across all eosinophil subgroups. Among the 98 patients on OCS, 47.8% were able to discontinue this treatment and the mean daily dose was decreased by 59.9%. The baseline ACT score was 14.1, increasing by a mean (SD) of 6.7 points (1.9) at 12 months. Adverse events related to mepolizumab were uncommon. Conclusions This real-world study of SEA patients confirms that mepolizumab is effective in reducing clinically meaningful exacerbations, improving lung function, and decreasing OCS dependence and mean OCS dose at 12 months, irrespective of baseline eosinophil counts.The members of "on behalf of the REDES Study group" is present in the Acknowledgements section.

Summary Memory deficits in narcolepsy with cataplexy type 1 (NT1) have been poorly studied, and the results are controversial. Patients with NT1 usually report memory deficits, which are not seen in objective memory assessments. This study aimed to assess attention and memory processes in NT1 patients using standardised neuropsychological tests and to compare the results with a control group. Performance in memory and attention tests was studied in 12 NT1 patients (diagnosed according to ICSD‐3 criteria) and the results compared with those of 14 control subjects. All participants completed questionnaires on sleepiness and depression symptoms. Significant differences were found in the depression symptoms questionnaire. Regarding neuropsychological assessment, NT1 patients performed worse in attention than the control group in that they processed fewer stimuli and achieved fewer correct stimuli. However, no significant differences were found in the memory test results, and the performance was similar between both groups. After application of the Holm‐Bonferroni correction, the only differences that remained significant were those in the ESS and in BDI‐II scores. Our results showed that memory processes are preserved in NT1 patients and that memory complaints may not be associated with an objective memory deficit. In addition, the significant difference observed for patients in the depression questionnaire could explain the subjective memory complaints.

Background Chronic obstructive pulmonary disease (COPD) usually occurs alongside other conditions. Few studies on comorbidities have taken into account the phenotypes of COPD patients. The objective of this study is to evaluate the prevalence of comorbidities included in the Charlson index and their influence on the survival of patients with COPD, taking phenotypes into account. Methods An observational study was conducted on a group of 273 patients who had COPD and underwent spirometry in the first half of 2011, with a median prospective follow-up period of 68.15 months. The survival of these patients was analyzed according to the presence of various comorbidities. Results Of the 273 patients, 93 (34.1%) died within the follow-up period. An increased presence of chronic ischemic heart disease (CIHD), chronic heart failure (CHF), chronic kidney disease (CKD), and malignancy was found in deceased patients. All of these conditions shorten the survival of COPD patients globally; however, when considering phenotypes, only CHF influences the exacerbator with chronic bronchitis phenotype, CKD influences the non-exacerbator phenotype, and malignancy influences the positive bronchodilator test (BDT) and exacerbator with chronic bronchitis phenotypes. In the multivariate model, advanced age (hazard ratio, HR: 1.05; p =0.001), CHF (HR: 1.74; p =0.030), and the presence of malignancy (HR: 1.78; p =0.010) were observed as independent mortality risk factors. Conclusion The survival is shorter in the presence of CIHD in overall COPD patients and also CHF, CKD, and malignancy for certain phenotypes. It is important to pay attention to these comorbidities in the comprehensive care of COPD patients.
