Obesity is increasingly encountered in dialysis patients, who have difficulty to lose weight. Several Transplant Centres require BMI <30-35 Kg/m2 at waiting-list. Thus, losing weight becomes a must for young obese patients, however the best policy to obtain it (if any) is not defined. The aim of the present case report is to suggest that tailored dialysis and intensive diets could be a successful combination, that should be tested on a larger scale. A 56-year-old obese male patient (BMI 37.7 kg/m²) on daily home hemodialysis since 10 months (ESRD due to focal segmental glomerulosclerosis) started a coach-assisted qualitative ad libitum diet. The diet, alternating 8 weeks of rapid weight loss and maintenance phases, was based on a combinations of different foods, chosen on the account of glycaemic index and biochemical properties. It was salt free and olive oil was permitted in liberal quantities. Dialysis duration was increased to allow weight loss, and dialysate Na was incremented to permit a strict low sodium diet. Over a period of 21 months, the patient attained a -18.5 Kg weight loss (50% overweight loss; BMI -6.3 Kg/m²), reaching the goal to be included in a kidney transplant waiting list. Main metabolic data remained stable (pre diet and end of the diet period: albumin 3.5-3.8 g/dL; HCO3 26.1-24.8 mmol/L discontinuing citrate) or improved (haemoglobin 11.4-12.1 g/dL, halving EPO dose; calcium 2.3-2.5 mmol/L; phosphate 1.5-1.5 mmol/L; PTHi 1718-251 pg/mL, reducing chelation).

Abstract
Obesity is increasingly encountered in dialysis patients, who have difficulty to lose weight. Several Transplant Centres require BMI <30-35 Kg/m2 at waiting-list. Thus, losing weight becomes a must for young obese patients, however the best policy to obtain it (if any) is not defined. The aim of the present case report is to suggest that tailored dialysis and intensive diets could be a successful combination, that should be tested on a larger scale. A 56-year-old obese male patient (BMI 37.7 kg/m²) on daily home hemodialysis since 10 months (ESRD due to focal segmental glomerulosclerosis) started a coach-assisted qualitative ad libitum diet. The diet, alternating 8 weeks of rapid weight loss and maintenance phases, was based on a combinations of different foods, chosen on the account of glycaemic index and biochemical properties. It was salt free and olive oil was permitted in liberal quantities. Dialysis duration was increased to allow weight loss, and dialysate Na was incremented to permit a strict low sodium diet. Over a period of 21 months, the patient attained a -18.5 Kg weight loss (50% overweight loss; BMI -6.3 Kg/m²), reaching the goal to be included in a kidney transplant waiting list. Main metabolic data remained stable (pre diet and end of the diet period: albumin 3.5-3.8 g/dL; HCO3 26.1-24.8 mmol/L discontinuing citrate) or improved (haemoglobin 11.4-12.1 g/dL, halving EPO dose; calcium 2.3-2.5 mmol/L; phosphate 1.5-1.5 mmol/L; PTHi 1718-251 pg/mL, reducing chelation). CONCLUSION: Daily dialysis may allow enrolling obese hemodialysis patients in intensive weight loss programs, under strict clinical control.
