Case Studies of Intradialytic Total Parenteral Nutrition in Nocturnal Home Hemodialysis.

The standard use of intradialytic parenteral nutrition has yielded heterogeneous clinical results. Confounders include patient selection, limited dialysis sessional duration, and frequency. Nocturnal home hemodialysis provides an intensive form of kidney replacement therapy (5 sessions per week and 8 hours per treatment). We present a series of 4 nocturnal home hemodialysis patients who required intradialytic total parenteral nutrition (IDTPN) as their primary source of caloric intake. We describe the context, effectiveness, and complications of IDTPN in these patients. Our patients received a range of 1200 to 1590 kCal (including 60 to 70 g of amino acids) with each IDTPN session for up to 27 months. As the availability of home hemodialysis continues to grow, the role of supplemental or primary IDTPN will require further research for this vulnerable patient population.
