Long-term outcome of kidney-pancreas transplant recipients with good graft function at one year

To assess the long-term outcome of kidney/pancreas transplantation, patients were identified who had good graft function at one year posttransplant and a minimum of 3 years' follow-up. Fifty recipients from 1987-92 met these criteria. Records were reviewed for graft survival, graft function, readmissions, and medical complications. Psychosocial adjustment and quality of life were assessed using the SCL-90-R and SIP surveys, respectively. Patient, kidney, and pancreas survivals were 94%, 86%, and 85% at five years (Kaplan-Meier), with a mean follow-up of 4.3 years. The 3 deaths were due to 2 sudden arrests at home (presumed to be cardiac events) and 1 episode of sepsis. Other graft losses were due to rejection, except for one case of sepsis. The remaining patients are normoglycemic (glucose 92+/-23 mg/dl) and have a creatinine of 1.8+/-0.6 mg/dl. Mortality after the first year was 0.9%/year. Estimated kidney and pancreas half-lives were 15+/-2 and 23+/-7 years, respectively. Hospitalization, acute rejection, graft pancreatitis, dehydration, and severe infections all decreased dramatically after the first year. While CMV was the most common infection in the first year, foot infections predominated thereafter. Retinal hemorrhage was infrequent. Sudden death (presumably cardiac) was the chief cause of mortality, while peripheral vascular disease resulted in several amputations. Fractures were common, suggesting the need for increased attention to bone demineralization. Psychosocial and quality of life evaluations were within normal limits. In conclusion, most complications specifically related to transplantation occur in the first year, but underlying disease renders these patients susceptible to a variety of cardiovascular, bone, and other disorders.
