Beta Blocker Dialyzability And Effectiveness In Chronic Hemodialysis Patients, Alvin Tieu Jul 2016

Beta Blocker Dialyzability And Effectiveness In Chronic Hemodialysis Patients, Alvin Tieu

Electronic Thesis and Dissertation Repository

Of the minimal information describing drug dialyzability, the majority was obtained prior to modern hemodialysis membranes. This study characterized the dialyzability of the most commonly prescribed beta blockers in patients undergoing high-flux hemodialysis. Eight subjects were recruited to a pharmacokinetic, 4-way crossover trial. Drug concentrations were measured using mass spectrometry and dialyzability determined by the arterial-venous difference and recovery clearance methods. A provincial-wide retrospective cohort study was designed to determine the effect of dialyzability on adverse clinical outcomes. Beta blocker efficacy can be hindered if substantial clearance occurs during dialysis. Our results demonstrate atenolol and metoprolol are extensively cleared during …


Development And Application Of Gadolinium Free Cardiac Magnetic Resonance Fibrosis Imaging For Multiscale Study Of Heart Failure In Patients With End Stage Renal Disease, Tori A. Stromp Jan 2016

Development And Application Of Gadolinium Free Cardiac Magnetic Resonance Fibrosis Imaging For Multiscale Study Of Heart Failure In Patients With End Stage Renal Disease, Tori A. Stromp

Theses and Dissertations--Physiology

Cardiac magnetic resonance (CMR) is a powerful tool to noninvasively image ventricular fibrosis. Late gadolinium enhancement (LGE) CMR identifies focal and, with T1 mapping, diffuse fibrosis. Despite prevalent cardiac fibrosis and heart failure, patients with end stage renal disease (ESRD) are excluded from LGE. Absence of a suitable diagnostic has limited the understanding of heart failure and obstructed development of therapies in the setting of ESRD. A quantitative, gadolinium free fibrosis detection method could overcome this critical barrier, propelling the advancement of diagnostic, monitoring, and therapy options. This project describes the development of a gadolinium free CMR technique and application …
