Early clinical, quality-of-life, and biochemical changes of "daily hemodialysis" (6 dialyses per week).

Background: Advantages associated with an increased frequency of hemodialysis have been reported previously. However, previous studies were either small or not controlled and did not detail early clinical, biochemical, quality-of-life, urea kinetic, and dynamic changes when patients switched from a conventional (3 times/wk) dialysis regimen to "daily" (6 times/wk) dialysis therapy when total weekly dialysis time was unchanged.

Methods: A prospective sequential study with 21 patients as their own controls was performed.

Utility of a peritoneal dialysis leukocyte test strip in the diagnosis of peritonitis.

Expeditious diagnosis of peritonitis remains a significant goal in the management of patients maintained on peritoneal dialysis. Several attempts to use leukocyte esterase reagent strips to diagnose peritonitis have been described. In this study we examined the usefulness of a new reagent strip, the PeriScreen Test Strip, in the diagnosis of peritonitis.

Use of Systemic Blood Urea Nitrogen Levels Obtained 30 Minutes before the End of Hemodialysis to Portray Equilibrated, Postdialysis Blood Urea Nitrogen Values.

Blood urea nitrogen (BUN) levels obtained at 30 minutes before the end of dialysis were found to be closely similar to equilibrated, postdialysis BUN values obtained 30 minutes after the end of dialysis. Because of this similarity, the former BUN values can be used to derive equilibrated urea reduction ratio, or equilibrated Kt/V instead.
