Efficacy
Statistical methods / analysis
Based on a previously published article (Nieuwdorp et al, J Appl Physiol 2008), the number required to detect a 0.2micrometre difference in the glycocalyx for a significance level of 5% and power of 80% in a paired design (i.e. measuring outcomes before and after an intervention) is n=10. We plan to recruit n=10 in each arm (total 20).

Summary
Brief summary
The glycocalyx is a particle that is important in maintaining blood vessel health. Patients with kidney disease have impaired blood vessel function, and previous studies have indicated that the glycocalyx is affected in those who have kidney disease. Laboratory studies indicate that the use of spironolactone, a common medication used for blood pressure, heart failure and to reduce protein in the urine, can have beneficial effects on the glycocalyx. The purpose of this study is to assess if the glycocalyx is affected in people who have kidney transplants, and whether spironolactone has any additional protective benefits on the glycocalyx.
