USA Demographics

This table (Table 4) shows the basic demographics for US primary DD pancreas transplants 01/01/99–05/15/2003 (SPK 74%, PAK 18%, PTA 8%). PTA recipients were youngest, PAK oldest and SPK intermediate (p=0.0001). There were more male pancreas transplant recipients than female in SPK and PAK categories (diabetic nephropathy is more frequent in men) and more women than men in PTA category (this reason is unclear since overall incidence of diabetes is similar in both sexes) (p=0.0001). Duration of diabetes prior to transplant was longest in PAK recipients and shortest in PTA, with SPK intermediate (p=0.0001).  Preservation time was shortest in SPK transplants and longest in PTA, with PAK intermediate (p=0.0001). Donor age was essentially the same among all three transplant categories (p=.37); only 2% of donors were over age 50. The number of donor HLA –A, HLA-B, HLA-DR mismatches was lowest in PTA and highest in SPK, with PAK intermediate (p=0.0001), showing an increased focus on HLA matching for PTA recipients. Waiting time was longest for SPK and shortest for PTA, with PAK intermediate (p=0.0001), reflecting the shortage of kidneys for transplant.  While the majority of recipients were white (80%); (type1 diabetes is higher in the white race compared to other racial groups), the number of minority (non-white) pancreas transplants, in particular African-American individuals (85%), has increased from 4% in 1987-90 and now comprises 12.6% in SPK transplants. Previous analyses have shown no difference in pancreas transplant outcome by recipient race.
