During ultra endurance events, athletes experience extreme physical and mental demands, sometimes at the limits of the adaptive response to human physiology. This is particularly true for the renal function, and some evidence for acute renal failure has already been shown, sometimes leading to dialysis. However, the precise mechanisms involved in acute renal failure in such ultra endurance races are not clearly elucidated. The aim of our study is to estimate glomerular filtration rate from serum and urinary creatinine and cystitin C at the beginning and at the end of a 110 km ultra endurance race. Our hypothesis is that during the ultra endurance race, renal function may be injured, with a risk for the athlete.
Acute kidney injury (AKI) is a common complication after cardiac surgery. Mismatch in renal oxygen demand-supply may be an important pathogenetic factor. Levosimendan has been shown to improve renal blood flow, glomerular filtration rate and renal oxygenation in healthy controls after cardiac surgery. In order to investigate the effect of levosimendan in patients with AKI after cardiac surgery, the investigators plan a randomized placebo controlled trial. 30 patients will receive levosimendan or placebo. Renal blood flow and filtration fraction will be measured using infusion clearance technique of para-aminohippuric acid and Chromium ethylenediaminetetraacetic acid (Cr-EDTA) respectively.
This is a two-staged study of a single dose of 200 mg of bosutinib given to subjects with renal impairment and matching healthy volunteers. In Stage 1, only subjects with severe renal impairment and subjects with normal renal function will be enrolled. Subjects with mild and moderate renal impairment will be enrolled in Stage 2 if the results from Stage 1 suggest a substantial difference in PK profiles between subjects with severe renal impairment and subjects with normal renal function.
