Transplantation for polycystic kidney disease.

Abstract

During the 4-year period from June 1977 to May 1981, a total of 108 patients with polycystic kidney disease and 2440 nonpolycystic patients received cadaver renal allografts in the Southeastern Organ Procurement Foundation (SEOPF) Prospective Study. There were no significant differences between the groups with and without polycystic disease in terms of recipient blood group, history of splenectomy, or preformed antibody status. As a group, transplanted polycystic patients underwent native nephrectomy more often, had a better HLA match, received less antilymphocyte serum (ALS), and were slightly older than nonpolycystic patients. Although proportionately fewer polycystic patients received pretransplant transfusions than nonpolycystic patients (P = .002), transfusion was associated with a significant increase in graft survival in the polycystic group (P less than .05), as well as in the nonpolycystic group (P less than .0001). Gene frequency analysis showed no HLA-A, or -B antigen linkage with polycystic disease. No significant differences existed between the polycystic and nonpolycystic groups in terms of overall graft and patient survival. However, transplanted polycystic patients died more frequently from bacterial sepsis (P less than .05), especially from gram-positive organisms (P = .01). Pretransplant bilateral nephrectomy did not affect the incidence of sepsis. However, following graft failure, patients with bilateral native nephrectomy had a greater incidence of severe anemia (50% versus 39%) and death (58% versus 25%; P less than .05) than those with unilateral nephrectomy or no nephrectomy. Treatment with ALS did not significantly improve graft survival in those with polycystic disease. A strong positive correlation was found between patient death and treatment with ALS only in the polycystic group (P less than .01). These findings indicate that the use of pretransplant bilateral native nephrectomy and posttransplant ALS should be judicious in the polycystic patient because they may be associated with increased morbidity and mortality.
