We report the case of a Lebanese infant born by normal delivery at 40 weeks of gestation. Weight and height at birth were 3200 grams and 49 cm respectively. Serum creatinine in the first week of life was 323 mmol/l (normal value for age is less than 20 mmol/l). Kidney ultrasound confirmed diagnosis of hypoplastic small kidneys. Conservative treatment of renal failure was initiated from the first days of life. Conservative management of renal failure included careful attention to fluid balance, maintenance of adequate nutrition and correction of hyperkalemia, acidosis, hyperphosphatemia and prevention of renal osteodystrophy by the use of dietary phosphate binders and vitamin D analogs. After a slight decrease of serum creatinine in the first three months of life, creatininemia increased progressively despite conservative treatment associated to hyperkalemia and severe pruritis due to hyperphosphatemia. Faced with the progression of renal failure, we decided to start automated peritoneal dialysis at seven months of life. Weight and height were respectively 6200 g and 63 cm. Serum creatinine was 432 mmol/L. Pruritis improved after starting peritoneal dialysis as well as appetite. At 20 months of life and a weight of 9.7 kg, a familial kidney transplant was performed. Immunosuppressive treatment included SimulectO, on day 1 and day 4, associated to mycophenolate mofetil, tacrolymus and prednisolone. The immediate post-transplant period was complicated by urinay tract infection due to BSLE E. coli. After four episodes of urinary tract infection due to resistant E coli associated to a non obstructive stone of 15 mm in the allograft kidney, we performed two sessions of lithotripsy and placed a double J stent. Biochemical urinary analysis did not reveal any causes for lithiasis. Stone disappeared as well as infection after lithotripsy. Renal function is normal for age one year after the kidney transplant. To our knowledge, this is the first reported case of a successful kidney transplant in a Lebanese infant with kidney failure since birth with kidney transplant performed at less than 10 kg of weight on the transplant day. Peritoneal dialysis is the treatment of choice for infants with chronic kidney failure. Familial or cadaveric kidney transplant should be encouraged and performed even in infants weighing less than 10 kg allowing them to have normal growth as well as social and school integration.

Current shortage in organ donors led to the expansion of criteria for organ donation placing organ preservation as one cornerstone for successful transplant, graft function and survival. The historical work of Belzer and Collins paved the way for key descriptions of physiopathology of cell ischemia and protection (cytokines roles, oxidative stress, energy shift to lactic acidosis and perfusion pressure changes). Good preservation means immediate recovery of function and prevention of chronic rejection. Two cooling approaches are available: static (SCS: simple cold storage) suitable for all organs, and dynamic (HMP: hypothermic machines perfusion) designed for kidneys and liver. A thorough discussion of historically manufactured and widely sold preservation solutions e.g. EuroCollins, UW solution (Viaspan®) as well as current used solutions e.g. Custodiol® and the new Celsior is available in this review. Obviously, every single organ exhibits different tolerance to warm and cold ischemia depending on its nature and demands after transplant. Future perspectives of organ preservation may be hidden in hibernators which may hold the enigmas of perfect human organ preservation.
