[Intensive weight-loss in dialysis: a personalized approach]

Area of Science:

• Nephrology
• Metabolic Medicine
• Bariatric Medicine

Background:

• Obesity is a significant challenge for dialysis patients, often hindering kidney transplant eligibility.
• Effective weight loss strategies for this population are not well-defined.

Observation:

• A 56-year-old male with end-stage renal disease (ESRD) on daily home hemodialysis (HHD) initiated a coach-assisted, intensive diet program.
• The diet involved alternating weight loss and maintenance phases, focusing on glycemic index and biochemical properties, with liberal olive oil and salt restriction.
• Hemodialysis parameters were adjusted, including increased duration and dialysate sodium, to support the weight loss program and dietary sodium restriction.

Findings:

• Over 21 months, the patient achieved 18.5 kg weight loss (50% of excess weight), reducing BMI by 6.3 kg/m².
• This weight loss enabled inclusion in the kidney transplant waiting list.
• Key metabolic markers remained stable or improved, including albumin, hemoglobin (halving EPO dose), calcium, phosphate, and parathyroid hormone levels (reducing chelation therapy).

Implications:

• Tailored daily hemodialysis combined with intensive dietary interventions shows promise for managing obesity in dialysis patients.
• This strategy may improve transplant candidacy and overall metabolic health in ESRD patients.
• Further large-scale studies are warranted to validate this combined approach.
