A weighty issue: refeeding an adolescent patient on dialysis.

Background: For malnourished patients with end stage renal disease (ESRD) on hemodialysis (HD), refeeding is complex; true weight (dry weight) gain must be accounted for as it accrues to safely dialyze.

Objective: This case describes the challenge of following true weight to appropriately adjust treatment for a patient with ESRD on HD requiring inpatient refeeding.

Methods: A 17-year-old female presented to an adolescent clinic after referral from her nephrologist for malnutrition and disordered eating. Her weight was 38.3 kg and height was 155.2 cm (76.2% of mean estimated body mass index, MEBMI). Her history was remarkable for a diagnosis of ESRD. The patient was admitted to the inpatient disordered eating program. The patient continued HD three times a week and was followed by nephrology. The team noted that the patient's dry weight for dialysis had not yet been adjusted, leading to increasingly aggressive dialysis. The nephrology team addressed the need for reassessments of dry weight by utilizing the "crit line" method.

Results: Frequent assessment allowed the nephrology team to account for intensive renourishment of the patient. After a 64 day hospital stay, the patient achieved 88.1% of MEBMI, calculated using her most up to date dry weight.

Conclusion: Among patients with malnutrition and ESRD requiring HD, it is imperative to determine a patient's dry weight at the beginning of refeeding so the treatment plan can be adjusted according to the dynamic, true weight of the patient. This case illustrates the importance of interdisciplinary teamwork when managing a patient with malnutrition and ESRD on HD.
