Clinical observations suggest that recipients of multiorgan transplants from the same donor can have disparate immunological reactions to each organ. We studied this phenomenon in 36 diabetic (streptozotocin-induced), bilaterally nephrectomized, immunosuppressed (cyclosporine, azathioprine, prednisone) pig recipients of simultaneous (same donor) pancreas (bladder drained) and kidney allografts by grading the histological intensity of rejection in biopsies of each organ at defined intervals posttransplant. Graft function was monitored by plasma glucose (PG) and urine amylase (UA) for the pancreas and serum creatinine (Cr) for the kidney. Interstitial rejection was graded as absent, mild, moderate, and severe in, respectively, 8%, 25%, 42%, and 25% of pancreas vs. 4%, 12%, 27%, and 57% of kidney biopsies at 1 week; and 0%, 43%, 29%, and 29% of pancreases vs. 10%, 0%, 30%, and 60% of kidneys at two weeks. Although the distribution of grades was similar in the two organs (P > 0.1), the grade of rejection for each pair at 1 week (n = 24) was discordant in 75% (42% differed by one and 33% by > or = 2 grades) and at 2 weeks (n = 7) in 57% (29% by 1 and 29% by > or = 2 grades). The inability to use the severity of interstitial rejection in one organ to predict the findings in the other is exemplified by the fact that for the two pancreases without interstitial rejection at one week, the corresponding kidney showed moderate or severe rejection, and for the 1 kidney without rejection the corresponding pancreas showed moderate rejection. Vascular rejection grades (absent, mild, moderate, severe) also showed a similar distribution for the pancreas (57%, 30%, 9%, 4%) vs. kidney (50%, 38%, 0%, 12%) at 1 week, and at 2 weeks (57%, 29%, 0%, and 14% for the pancreas vs. 78%, 11%, 0%, and 11 for the kidney) (P > or = 0.64). However, the grading of vascular rejection in organ pairs was dyssynchronous in 54% at 1 week (n = 22) and 29% at 2 weeks (n = 7). No vascular rejection in the pancreas with rejection in the kidney was seen in 5 pairs at 1 week (23%) and 0 at 2 weeks (0%), while no rejection in the kidney with rejection in the pancreas was seen in 5 pairs at 1 week (23%) and 2 pairs at 2 weeks (29%).(ABSTRACT TRUNCATED AT 400 WORDS)
