Optimizing the Diagnostic Approach to Cephalosporin Allergy Testing (DACAT)
Cephalosporin antibiotics are commonly used but can result in allergic reactions and anaphylaxis. There is no clear diagnostic approach for cephalosporin-allergic patients, and guidance for the use of other antibiotics in allergic patients is based on side chain chemical similarity and limited skin testing evidence. This project includes a clinical trial and mechanistic studies to optimize the approach to cephalosporin allergy and advance future diagnostics.

Escitalopram in Asthma Patients With Frequent Exacerbation
Antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), such as escitalopram are widely used for mood and anxiety disorders. However, they have also been explored, with promising findings, for a variety of disorders outside of psychiatry. Clinical studies of SSRIs in depressed people with asthma were associated with decreased asthma exacerbations and improvement in asthma control. In this study, the number of asthma exacerbations will be assessed as the primary outcome measure in patients using escitalopram vs. placebo.
