LATE FUNCTION OF THE ORTHOTOPIC LIVER HOMOGRAFT

The clinical and histologic features of the liver homografts of long term dog survivors following orthotopic hepatic homotransplantation have recently been described (1). The liver function of 9 of these animals was studied 98 to 442 days after operation. In each case immunosuppressive therapy was discontinued from 110 to 131 days after transplantation. In 1 (SS-4), subsequent deterioration of homograft function occurred necessitating resumption of azathioprine.

RESULTS

The results of standard liver function tests are shown in Table I. One animal (S35-4) was completely normal; the other 8 showed varying degrees of hepatic dysfunction. A 5 hr. glucose tolerance test was normal in 5 of 6 dogs. Normal hyperglycemic response to 100 μg. of intravenous glucagon was present in 5 of 7 animals tested, while a minimal glycogenolytic response appeared in 2 (SS-4; Sch-9). In 5 dogs with good liver function, plasma cholesterol, phospholipids, and triglycerides were normal both on a regular kennel diet and a 117 gm. per day fat diet.

SUMMARY

In general the hepatic functional derangements paralleled the microscopic abnormalities previously described (1). The causes of the 4 deaths were liver failure (ICBM-13; SS-4), liver failure and a bleeding duodenal ulcer (I-10), and perforated duodenal ulcer (S35-18). The clinical condition of the survivors corresponds to their liver function. This long term retention of life-sustaining liver function after hepatic homotransplantation is distinctly encouraging.
