Intradialytic Drug Removal by Short-daily Hemodialysis

• Status: Completed
• Trial end date: 2009-09-01
• Target enrollment: 0
• Participant gender: All

Summary

Short-daily hemodialysis is increasingly becoming a preferred alternative to the conventional intermittent (three times per week) hemodialysis schedule. Studies have shown that short-daily dialysis improves a patient's quality of life, high blood pressure, anemia and calcium-phosphorus balance. Infection, however, will likely remain a persistent problem for dialysis patients regardless of the frequency of treatments. There is currently a wealth of information to guide doctors on how much and how frequently to give an antibiotic for patients who receive intermittent (thrice weekly) hemodialysis. However, there is very little information on how to prescribe antibiotics for patient's receiving short-daily hemodialysis. This study will develop drug dose guidelines for patients receiving short-daily hemodialysis for three frequently used antibiotics, vancomycin, levofloxacin and gentamicin. These guidelines will assist doctors so that patients receive the most effective dose and frequency of an antibiotic to treat their infection.

The following is the study hypothesis which will be tested with two-sided, one sample t-tests comparing the AUC observed to historical measures8.

1) Vancomycin, levofloxacin and gentamicin are removed to a greater extent by short-daily hemodialysis than intermittent hemodialysis.

The following are the specific aims:

1. Determine the interdialytic pharmacokinetics of vancomycin, gentamicin, and levofloxacin by short-daily HD.

2. Determine the extent of vancomycin removal when administered during the last hour of short-daily HD.

3. Develop drug-dosing guidelines for vancomycin, gentamicin and levofloxacin for patients receiving short-daily HD.
