  • Title: The protective effect of methyl prednisolone on the machine-preserved kidney.
    Author: McCabe RE, Lattes CG, Lorieo DR, Hashim GA, Fitzpatrick HF.
    Journal: Am Surg; 1980 Jun; 46(6):335-9. PubMed ID: 6994528.
    Abstract:
    Fifty cadaveric transplants were reviewed to determine whether graft failure was related to the method of preservation. Twenty-eight transplants were preserved by a combination of cold storage and perfusion with cryoprecipitated plasma. Twenty-two transplants were preserved by continuous perfusion with Plasmanate. The perfusate of 14 plasma-perfused kidneys contained 1.0 g of methyl prednisolone, whereas the Plasmanate contained only 100 mg hydrocortisone. Fourteen plasma-perfused kidneys functioned immediately (Group I), and 14 showed delayed function. Seventeen of 22 Plasmanate kidneys (Group III) functioned immediately. Of the Group I kidneys, 13 of 14 functioned for three to eight months, and eight (57%) are still functioning after two years vs. only three of 14 (21%) in Group II. Eleven of the 14 long-term surviving grafts were pretreated with methyl prednisolone. Only nine of the Plasmanate kidneys (39%) lasted more than three months; five (22%) survived more than 12 months. None of the Plasmanate-perfused kidneys that failed to function immediately lasted three months. It is concluded that immediate restoration of renal function after transplantation is a favorable sign for long-term graft survival. The addition of methyl prednisolone to the perfusate may enhance the survival of kidney allografts.
