ABSTRACT
Background: The prevalence of cardiovascular events (CVEs) in patients with asthma varies amongst studies, with little evidence as to their prevalence in patients treated with monoclonal antibodies (mAbs). In this retrospective, observational study, we aimed to evaluate the prevalence of CVEs in patients with T2 and non-T2 asthma and to identify risk factors associated with CVEs. Methods: A total of 206 patients with severe asthma were included. Demographic variables, respiratory comorbidities and cardiovascular risk factors were collected, along with respiratory function, laboratory parameters and respiratory pharmacotherapy, including treatment with mAbs. Results: A total of 10.7% of the patients had any CVE from the date of asthma diagnosis, with a higher risk in those patients with chronic obstructive pulmonary disease (odds ratio [OR] = 5.36, 95% CI 1.76-16.31; p = 0.003), arterial hypertension (OR = 2.71, 95% CI 1.13-6.55; p = 0.026) and dyslipidaemia (OR = 9.34, 95% CI 3.57-24.44; p < 0.001). No association between mAb treatment and a CVE or between time of mAb treatment and the event was found. No significant differences were observed between the T2 and non-T2 cohort. After a multivariate analysis, dyslipidaemia was identified as an independent risk factor (OR = 13.33, 95% CI 4.49-39.58; p < 0.001), whereas regular use of inhaled corticosteroids was associated with a reduced risk of a CVE (OR = 0.103, 95% CI 0.021-0.499; p = 0.005). Further research is needed to fully understand the relationship between severe asthma and CVEs. Conclusions: This study suggests that patients with severe asthma experience a higher percentage of CVEs compared with the general population.
ABSTRACT
BACKGROUND: Biologics have revolutionized the treatment of many diseases. In this regard, omalizumab (OMA), an anti-IgE monoclonal antibody, is the recommended therapeutic option for patients with chronic spontaneous urticaria (CSU) refractory to second-generation H1-antihistamines. Several studies confirm the efficacy and safety of the drug. However, the literature focusing on the elderly population is scarce, as this age group is often excluded from clinical trials. Therefore, the pharmacological treatment of CSU in elderly patients is a challenge that is increased by their comorbidities and consequent polypharmacy. OBJECTIVES: We describe the real-life safety profile of OMA in elderly patients (≥70 years) with CSU and chronic inducible urticaria (CIndU). We aimed to provide data for daily clinical practice in this vulnerable patient group. METHOD: A retrospective review was performed of the records of patients with CSU/CIndU from May 2003 to December 2019 in the Hospital Universitario La Paz. We describe qualitative and quantitative data according to measures of central tendency. Comparisons between qualitative and quantitative data were performed with the Mann-Whitney U test and the Fisher's test for qualitative variables. A p value <0.05 was considered statistically significant. RESULTS AND CONCLUSIONS: Eighty-nine patients were included, divided into two groups (<70 vs. ≥70 years). The overall rate of adverse events (AEs) was 48%, mainly mild. No association between age and AE was found (p = 0.789). No serious AE such as anaphylaxis was detected. CSU predominated in both groups. CIndU was less prevalent in the elderly (p = 0.017). There was no association between age and the other variables. Although the frequency of neoplasms was slightly higher in the elderly with OMA, we found no difference compared to the incidence of neoplasms in the general population. Therefore, our data suggest that OMA may be a safe treatment in elderly people with CSU/CIndU for prolonged periods of treatment, although further studies with larger samples are needed to corroborate our observations.

OBJECTIVE: To assess the safety of biological therapy for severe T2 asthma (omalizumab, mepolizumab, benralizumab and reslizumab) under real-life conditions in elderly patients older than 70 years. METHODS: Retrospective data collection including clinical characteristics, comorbidities, treatment, disease control and adverse events (AE) of all patients with severe asthma on biological therapy older than 70 years seen in the Severe Asthma Unit of our hospital. RESULTS: Of 147 patients with severe asthma being treated with biologics, 21 patients older than 70 years were included. The median age of these patients was 76.3 years (range 71-86) and the majority were women (n = 18, 85.7%). There were 9 patients (42.9%) who experienced an AE related to biological treatment. Four (44.4%) were in treatment with omalizumab, two (22.2%) with mepolizumab, two patients (22.2%) with reslizumab and one (11.1%) with benralizumab. The median FEV1 (%) was 66%. These patients had a considerably higher body mass index (BMI). No significant differences were found for any other variable. Most of the AE reported were considered mild with the exception of one case of systemic AE (anaphylaxis) associated with omalizumab. CONCLUSION: This study indicates that the prescription of biological therapy in elderly patients with severe asthma seems to be safe. More evidence is needed in this particular population.
