A thrice weekly in-center nocturnal hemodialysis program

Area of Science:

• Nephrology
• Internal Medicine
• Cardiovascular Diseases

Background:

• High mortality rates persist among hemodialysis (HD) patients.
• Extended HD session times and reduced ultrafiltration rates are linked to lower mortality.

Purpose of the Study:

• To evaluate the efficacy and impact of a thrice-weekly nocturnal hemodialysis program.
• To assess changes in urea clearance, serum phosphorus, and ultrafiltration rates in HD patients.

Main Methods:

• A cohort of 16 patients initiated thrice-weekly nocturnal hemodialysis in May 2005.
• Key parameters including Kt/V urea, serum phosphorus, and ultrafiltration rates were measured at baseline and 6 months.
• Psychosocial assessments were conducted at baseline and 6 months.

Main Results:

• Nocturnal HD significantly improved Kt/V urea (2.6 vs. 1.2) and reduced serum phosphorus (4.4 vs. 5.3 mg/dL) after 6 months.
• The ultrafiltration rate decreased from 10.3 mL/h/kg at baseline to 5.9 mL/h/kg at 6 months.
• No significant changes were observed in psychosocial assessments.

Conclusions:

• Long, in-center thrice-weekly nocturnal hemodialysis leads to improved urea clearance and reduced serum phosphate.
• This HD modality effectively lowers the ultrafiltration rate below 10 mL/h/kg.
• Nocturnal hemodialysis shows no negative impact on quality of life measures.
