Efficiency of high permeable membranes in hemodiafiltration in children: an optimal method of purification.

Hemodiafiltration (HDF) combines hemodialysis (HD) and hemofiltration (HF) and so allows an optimal purification by combining diffusive process (low molecular weight compounds) with convective mass transport (middle molecular weight compounds). A high permeable membrane is analysed (clearance, extraction coefficient, sieving coefficient) at 30 min and 150 min session time in HD, HF and HDF conditions. There is not a better elimination of urea in HDF versus HD while HDF allows an optimal elimination of uremic toxins in the range of low and middle molecular weight compounds. A high (optimal?) filtrate flow, with a minimal risk, is given by the formula: QUF = 1/3 QB. Sieving coefficient in HF condition of the other membranes generally employed in pediatric HDF demonstrated a great variability for the cut off.

[Temporary auxiliary orthotopic transplantation of a reduced liver for fulminant hepatitis. A successful case in a child].

A 4 years boy with fulminant hepatitis due to virus A, underwent a temporary auxiliary liver transplantation. The graft which consisted in an adult reduced-liver, was implanted orthotopically after a left hepatectomy was performed on the recipient own liver. A good liver function was immediately restituted and the remaining native liver, that was 90% necrotic at time of transplantation, regained normal histological structure within 3 months. The auxiliary graft was then removed and immunosuppressive therapy permanently stopped.
