One hundred seventy orthotopic liver transplants were performed under conventional immunosuppression with azathioprine and steroids with 1- and 5-year survivals of 32.9 per cent and 20.0 per cent, respectively. Since the introduction of cyclosporine-prednisone therapy in March 1980, 313 primary orthotopic liver transplants have been performed. Actuarial survivals at 1 and 5 years have improved to 69.7 per cent and 62.8 per cent, respectively. Biliary atresia is now the most common indication for liver replacement. In adults, primary biliary cirrhosis and sclerosing cholangitis have become more common indications for transplantation, and alcoholic cirrhosis and primary liver malignancy as indications have declined. Early enthusiasm for liver transplantation in patients with hepatic cancer has been tempered by the finding that recurrence is both common and rapid. An increasing number of patients with inborn errors of metabolism originating in the liver are receiving transplants, including patients with Wilson's disease, tyrosinemia, alpha-1-antitrypsin deficiency, glycogen storage disease, familial hypercholesterolemia, and hemochromatosis. Survival in this group of patients has been excellent (74.4 per cent at 1 and 5 years). A hemophiliac who received a transplant for postnecrotic cirrhosis has survived and may have been cured of his hemophilia. About 20 per cent of patients require retransplantation for rejection, technical failure, or primary graft failure. Only four of the patients receiving retransplants under conventional immunosuppression survived beyond 6 months, and all died within 14 months of retransplantation. Sixty-eight patients have received retransplants under cyclosporine-prednisone. Thirty-one patients are surviving, all for at least 1 year. Six of the twelve patients requiring a third transplant are alive 2 to 3 years after the primary operation. An aggressive approach to retransplantation in the patient with a failed graft is justified.

Surgical bile flow restoration in extrahepatic biliary atresia (EHBA) does not prevent the development of ongoing hepatic fibrosis and cirrhosis. Portal connective matrix was studied on liver biopsies obtained from seven children submitted to portoenterostomy. Electron microscopy and immunohistochemical techniques (using specific antibodies directed against collagen isotypes and associated glycoproteins) were performed. The study of extracellular and cellular components of connective matrix demonstrated the existence of two distinct areas according to their situation with regard to ductular proliferation: loose connective matrix--mainly composed of fibronectin, type III collagen, type IV collagen and laminin--associated with microvessels and myofibroblasts proliferation characterized periportal zones adjacent to bile ductules; in areas distant from ductular proliferation, connective matrix appeared dense, composed of type I and type III collagen associated with fibroblasts. The connective matrix pattern observed in periductular areas can be compared to that described in cicatricial and hypertrophic processes where the myofibroblastic cell population is known to play an important role in fibrosis development. Although the connective matrix activation process remains unclear in EHBA, it may be suggested that activation of a connective tissue cellular clone might be responsible for this portal fibromatosis.

We measured fasting plasma amino acids in 26 children aged 6 months to 5 years with extrahepatic biliary atresia and cirrhosis and compared them with fasting values in 95 normal control children aged 4 months to 12 years. We found that the cirrhotic children had elevations of total free plasma amino acids implying reduced hepatic metabolism of amino acids and that the molar ratio of the branched chain amino acids (isoleucine, leucine, and valine) to the aromatic amino acids (phenylalanine and tyrosine) was significantly depressed. Methionine was also markedly elevated, and taurine concentrations were significantly decreased. Manipulation of the amino acid distribution in dietary protein to normalize plasma amino acids prior to orthotopic hepatic transplantation may be helpful in improving amino acid utilization.

The weights of the spleens of series of patients with various disorders of children dating from birth or early infancy and causing splenomegaly, with or without cirrhosis of the liver, were analyzed. The linear regression equation for spleen weight versus age in months for each disease was derived, and the rate constants from these equations were adjusted for the age range of the patients in each group. The original data of Coppoletta and Wolbach were used for normal values. The rates of splenic growth of appropriate entities for which the regression equation could be computed fell into three groups, with adjusted rate constants (growth of spleen in grams per month) of 6.53-6.95 (biliary atresia, thalassemia, and cirrhosis following neonatal hepatitis), 2.30-2.62 (cirrhosis of alpha-1-antitrypsin deficiency, infantile polycystic disease, and spherocytosis), and 1.06-1.11 (cystic fibrosis and idiopathic thrombocytopenic purpura). These classes of splenic growth rates are approximately 10, 3.7, and 1.6 times the normal growth rate (0.67 g/mo). Rate constants could not be computed for the categories cirrhosis following viral hepatitis and hemolytic anemia other than spherocytosis and sickle cell anemia, and the numbers of patients with splenic vein obstruction, cirrhosis with the cholestatic syndrome of parenteral alimentation, hypoplastic anemia with hemosiderosis, tyrosinemia, Byler's disease, congenital hepatic fibrosis, and Wilson's disease were too few for analysis. The significance of the finding of classes or "quantum groups" of splenic growth rates in disorders of children, dating from birth or early infancy and causing splenomegaly, is uncertain. Comparable data on adequate series of patients with other appropriate disorders will be necessary.

Fifty four infants with hepatobiliary disease and conjugated hyperbilirubinaemia of more than two weeks' duration were identified in a defined area of south east England in a prospective study between January 1971 and December 1973. The overall incidence was one case per 2500 live births. The cases were regularly reviewed and all survivors except one were assessed at age 10 years. Nine of 11 with extrahepatic biliary atresia died from liver disease by 2 years of age, one died at 5 years, and the survivor has cirrhosis with portal hypertension. Four out of seven with alpha 1 antitrypsin deficiency died aged 1 to 3 years from liver disease and one of the survivors has cirrhosis. All three infants with intrauterine infection and one with chromosomal abnormality died in infancy. Three children with other associated factors, choledochal cyst, galactosaemia, and rhesus isoimmunisation, recovered completely with no persisting liver disease. Two of 29 with cryptogenic hepatitis died, but only a further two have signs of persisting liver disease. Perinatal complications were more common in this group. Four of the 27 children surviving to the age of 10 years are educationally subnormal. Prognosis for infants with intrahepatic liver disease in the absence of known associated factors is good and every effort should be made to minimise the short term effects of cholestasis.

During the past 6 years, 25 consecutive patients with esophageal variceal hemorrhage were treated by esophageal endosclerosis (direct injection of varices with a sclerosing agent). The primary disease in the 25 children was portal vein thrombosis (11 patients), biliary atresia (nine patients), and hepatic cirrhosis from cystic fibrosis (three patients), alpha 1-antitrypsin deficiency (one patient), and neonatal hepatitis (one patient). Thirteen patients were treated during acute, major variceal hemorrhage. Esophageal endosclerosis was repeated at regular intervals until all esophageal varices were obliterated. Twenty-one patients completed therapy. Four patients died: one of a complication of therapy and three of the primary disease. Other than the one death, complications were minor. Recurrent esophageal variceal hemorrhage has not been encountered in follow-up from 9 months to 6 years after completion of therapy.

Retrospective analysis of 97 children aged 3 months to 15 years presented for liver transplantation in our clinic indicates that children with extrahepatic biliary atresia (BA) show a cumulative survival of only 27% after 2.5 years of observation without transplantation. Children with cirrhosis of the liver of other origin (C) have an even worse cumulative survival rate of only 10% after the same time and treatment. Liver transplantation seems to be very urgent if there is a parallel drop of activity of pseudocholinesterase (CHE) below 1100 U/l, a drop of prothrombin test (PT) below 60% and a concomitant increase of concentration of bilirubin (Bili) and total serum bile acids (TBA) to 380 and 120 mumol/l respectively. In order to improve medical care of children with endstage liver disease it is mandatory to use all potential donor offers and to develop new surgical techniques such as transplantation of liver segments.

Liver transplantation has become a clinical therapeutic modality for end stage liver diseases. The results achieved in children are better than in adults: in T.E. Starzl unique experience in Pittsburgh, USA, the survival rate at one and four years are 75 and 70% respectively. Complete rehabilitation of these children can nowadays be expected. Between March 1984 and June 1985, 8 children received an orthotopic liver transplantation at the University of Louvain Medical School in Brussels, Belgium; one child received two transplantations after acute and irreversible rejection of a first ABO incompatible graft. The indications were biliary atresia in five (polysplenia in one), biliary hypoplasia in one, alpha-1-antitrypsine deficiency in one and Crigler-Najjar syndrome type I in one. The age of the patients at the time of liver replacement was 12 to 18 months in four, 8 to 13 years in four. Six patients are alive after 17, 14, 12, 10, 3 and 3 months; the two youngest children deceased during the first postoperative month. The Kaplan-Meyer one year survival rate is 75%; all surviving children are in excellent clinical condition with a normal liver function. The 9 transplanted livers were harvested from multiorgan cerebral death donors with the exception of one neonate whose liver alone was removed; 4 were retrieved locally, the five others were offered by foreign hospitals through the organ procurement agencies (Eurotransplant, France-Transplant, U.K. Transplant). Due to appropriate logistics with air flight transportation of the harvesting team when indicated, the total ischaemia time was kept below 6 hours in every case. Two small children underwent a left lobe orthotopic transplantation after ex vivo right trisegmentectomy of the liver retrieved from an older donor with one long term survival. The indications for liver transplantation in children are end-stage liver diseases consisting of a) cholestatic diseases among which the most frequent is biliary atresia after unsuccessful Kasai procedure followed by familial cholestasis (Byler syndrome) and the paucity of the intrahepatic bile ducts of the syndromatic (Alagille syndrome) or non syndromatic type. b) the metabolic diseases resulting either in cirrhosis with liver failure (alpha-1-antitrypsin deficiency, Wilson disease, glycogen storage disease type I and IV, protoporphyria) or in extrahepatic complications of enzymatic deficiency of an otherwise normally functioning liver (Crigler-Najjar syndrome type I, familial hypercholesterolemia and perhaps oxalosis). c) the hepatocellular diseases either chronic with cirrhosis of various origin or acute, eg. toxic hepatitis.(ABSTRACT TRUNCATED AT 400 WORDS)

The surgical results in 39 children operated on for biliary atresia at Red Cross War Memorial Children's Hospital between January 1975 and January 1985 are reported. The mean age at operation was 12.8 weeks (range 6 weeks-6 months). In the first 4 years no patient had sustained bile drainage after operation. Since 1979 16 of 32 patients (50%) have had significant bile drainage. Of these, 8 are alive and have been followed up from 6 months to 6 years after operation. Five are jaundice-free and well. The other 3 are mildly jaundiced, have evidence of ongoing liver damage, and have a poor prognosis. The deaths were due to progressive liver damage with liver failure, portal hypertension, and intercurrent infection. Cholangitis after 'successful' porto-enterostomy was the main cause of poor prognosis and can be related to the age at referral and the presence of cirrhosis of the liver at the time of surgery; thus bile drainage does not necessarily equate with cure. Early referral of infants with conjugated hyperbilirubinaemia to a major centre is of paramount importance if we are to improve the prognosis.

Lectin affinities of AFP were analyzed using Con A sepharose chromatography and crossed immuno-affino-electrophoresis. With Con A, AFP was divided into three subfractions, nonbound, loosely-bound and tightly-bound by chromatography, or two subfractions, nonbound and bound by electrophoresis. Con A nonbound subfraction was small in percentage in hepatocellular carcinoma (HCC), neonatal hepatitis, congenital biliary atresia (CBA), liver cirrhosis (LC) and cord sera. In contrast with these, the increase of Con A non-bound AFP was observed in yolk sac tumor (YST) and metastatic liver cancer (Meta). With LCA, AFP was divided into three subfractions: nonbound, loosely bound and tightly bound. Loosely bound fraction was very small in every specimen. AFPs from cord sera and LC showed uniform LCA affinity pattern, but AFPs from HCC were not uniform. Our data suggest that the analyses of lectin affinity of AFP serve as a diagnostic tool in differentiating (1) HCC from YST, (2) HCC from Meta, (3) CBA or neonatal hepatitis from YST and (4) LC from some cases of HCC.
