Brief Summary

The optimal frequency of hemodialysis treatments in patients with incident end-stage kidney disease in not known. This pilot trial will randomize patients with incident end-stage kidney disease due to chronic kidney disease progression to two different regimens of hemodialysis: i) twice-weekly hemodialysis for six weeks with adjuvant pharmacologic medications followed by thrice-weekly hemodialysis, or ii) thrice-weekly hemodialysis. The study will test feasibility of stepwise hemodialysis, and the effects of the two regimens of hemodialysis on residual kidney function.

  6 months, 12 months, 24 months

Secondary Outcomes (3)

• 24-hour Urine Volume

  Baseline, 6 Weeks, 12 Weeks, 24 Weeks

• Change in Residual Kidney Function - Urea Clearance

  Baseline, 6 Weeks, 12 Weeks, 24 Weeks

• Change in Residual Kidney Function - Creatinine Clearance

  Baseline, 6 Weeks, 12 Weeks, 24 Weeks

Limitations and Caveats

Our results should be interpreted in the context of several limitations. Given (1) the imbalances in baseline characteristics between the 2 groups, (2) the small sample size, and (3) the time-delineated twice-weekly HD, the effect estimates are solely exploratory. Our testing of a time-delineated prescription of twice-weekly HD for 6 weeks may leave lingering concerns as to whether incremental HD with longer periods of twice-weekly HD can be effectively and safely implemented.
