The prevalence of symptomatic duodenal ulcer (DU) assessed primarily in alcoholic males with cirrhosis is estimated to be approximately fivefold increased compared to the normal population. Little information is available, however, as to the prevalence of DU in nonbleeding, nonalcoholic subjects with cirrhosis. In order to estimate the prevalence of DU in males with various types of cirrhosis and its relation to the degree of portal hypertension, 216 male cirrhotic patients (165 with parenchymal liver disease and 51 with cholestatic liver disease) being evaluated for liver transplantation at the University of Pittsburgh between January 1985 and June 1987 underwent pan-upper gastrointestinal endoscopy. The prevalence of DU in each group was 7.8%. However, among the various subgroups it was as follows: chronic active hepatitis due to HBV: 9.4%, alcoholic: 12.2%, cryptogenic: 3.5%, autoimmune chronic active hepatitis: 6.6%, primary sclerosing cholangitis (PSC): 9.5%. The reference data for this study consist of data reported in the literature obtained in 355 healthy asymptomatic male volunteers. The prevalence of DU in this group is significantly less than in the study group (2.2% vs 7.8%; P less than 0.005). While the estimated risk for a DU is increased 3.71-fold (95% CI: 8.74, 1.57; P less than 0.005) in cirrhotic males in general as compared to normal males, only the subgroups with CAH due to HBV, alcoholism, and PSC were found to have an increased estimated risk of DU (all at least P less than 0.01). No association between the prevalence of DU and degree of portal hypertension could be demonstrated in either group.

The frequency of diseases responsible for non-cirrhotic intrahepatic portal hypertension varies according to the patients' geographical origin. The condition is rare in Europe. These diseases may be classified into two main groups, sometimes intricated: 1) fibrosing diseases due to chronic active hepatitis or to a chronic cholestatic disease (primary biliary cirrhosis, primary sclerosing cholangitis, sarcoidosis, congenital hepatic fibrosis); 2) vascular diseases occluding the portal vein (schistosomiasis, idiopathic portal hypertension, regenerative nodular hyperplasia), the intrahepatic veins (alcoholism, drugs, radiations, toxic substances) or the sinusoids (peliosis, amyloidosis, hypervitaminosis A, blood diseases). The prognosis of these diseases, (apart from that of certain responsible or associated diseases), is better than the prognosis of cirrhosis, since the liver cell functions are normal or little altered for a long time. However, in most cases the treatment of non-cirrhotic intrahepatic portal hypertension is similar to that of cirrhotic portal hypertension.

Between July 1987 and May 1989, 11 liver transplants were performed on 10 patients at the University Hospital of Geneva. Of 15 patients evaluated for elective transplantation, 10 were accepted and put on the waiting list. 5 patients were rejected because of a contraindication or because another treatment seemed preferable. 8 transplantations were eventually performed. Emergency transplantation was considered for 6 patients, but could be performed in only 3. Indications for transplantation were as follows: one hepatocellular carcinoma in a non-cirrhotic patient, 2 post-hepatitis cirrhoses (one B and one non-A-, non-B), 3 primary biliary cirrhoses, one autoimmune cirrhosis, one primary sclerosing cholangitis, one cirrhosis on alpha-1-antitrypsin deficiency, and one fulminant B-Delta hepatitis. Most of these patients had advanced liver disease and a limited life expectancy. 8 of the 10 patients transplanted are nevertheless alive and none is hospitalized at the present time. More than mere survival, however, quality of life regained after transplantation prompts us to consider transplantation early in the progress of the disease. Earlier evaluation of patients would make transplantation feasible soon after the first complication of the disease. This attitude would probably prevent patients from dying while on a waiting list and decrease operative as well as early postoperative risks. Better information and coordination regarding potential donors is necessary in Switzerland to obtain better results in organ transplantation.

To obtain information on the prevalence and clinical and laboratory correlates of osteopenia in patients with chronic liver disease, we measured bone densities and 30 selected laboratory variables in 133 subjects (70 men, 63 women) with liver disease. Thirty-two had alcoholic liver disease, 18 had primary biliary cirrhosis, 16 had primary sclerosing cholangitis, 48 had other forms of cirrhosis (cryptogenic, posthepatic) and 19 had chronic hepatitis or fibrosis without cirrhosis. Bone densities of the lumbar spine and three sites of the proximal femur (neck, Ward's triangle, greater trochanter) were estimated by dual-photon absorptiometry. Bone densities at all sites were significantly correlated to one another (r = 0.4 to 0.9; 95% confidence intervals = 0.24-0.54 to 0.81-0.90; p less than 0.0001 for all). Compared with an age- and gender-matched reference group, patients with liver disease had highly significant decreases in bone densities (greater than 2 standard deviations below control values; p less than 0.0008 at all sites). Decreases were particularly marked (24% to 42%) at Ward's triangle, the site of the femoral neck particularly prone to fracture. The prevalence of decreased bone densities ranged from 10% to 56%, depending on the site studied and the nature of the liver disease. Among 30 laboratory variables studied, there were significant (p less than 0.05) correlations with bone densities at more than one site for urinary creatinine (r = 0.21, 0.25), urinary calcium (r = -0.18, -0.23), serum total alkaline phosphatase (r = -0.18, -0.27) and the liver-1 isozyme of serum alkaline phosphatase (r = -0.19, -0.26).(ABSTRACT TRUNCATED AT 250 WORDS)

Pi phenotype was determined in 335 patients with liver diseases and compared with the results in 2830 healthy blood donors. Eleven of 335 patients had phenotype MZ (3.3%, compared with 2.9% in healthy blood donors (NS]. None of 53 patients with autoimmune chronic active hepatitis had the MZ phenotype, but it was found in 2 of 18 patients (11.1%) with cryptogenic cirrhosis, 3 of 78 (3.8%) with alcoholic liver cirrhosis, 2 of 36 (5.6%) with primary sclerosing cholangitis, and 1 of 26 (3.9%) with primary biliary cirrhosis. Altogether, 3 of 335 patients were homozygous for Pi ZZ and had cirrhosis. One of them (a male) developed a hepatoma and died. We conclude that the reported association between Pi MZ phenotype and chronic non-B active hepatitis does not seem to include patients with autoimmune chronic active hepatitis, whereas the possibility of an association between cryptogenic cirrhosis and the MZ phenotype cannot be excluded.

Proliferation of the two types of bile ductules, typical and atypical, in the portal and periportal areas was examined in various liver diseases other than cirrhosis to determine any difference in their immunohistochemical properties and presumed histogenesis. While the typical ductules with a well-formed lumen were frequently seen in a large spectrum of diseases, atypical ductules with a poorly defined lumen were encountered much more frequently in prolonged biliary diseases, including primary biliary cirrhosis and primary sclerosing cholangitis, than in nonbiliary hepatic diseases. Immunocytochemically, cytoplasmic keratin was intensively positive in typical ductules, and the degree of its intensity and extent was variable in atypical ductules. Simultaneously, some of the periportal hepatocytes revealed weak staining for keratin. Luminal borders of typical ductules usually revealed an expression of both carcinoembryonic antigen and epithelial membrane antigen, while atypical ductules and periportal hepatocytes lacked epithelial membrane antigen. The atypical ductules, together with the adjoining hepatocytes, appeared on occasion to form anastomosing cords in prolonged biliary diseases. Thus, atypical ductules seem likely to originate from ductular transformation of the periportal hepatocytes and the typical ductules might result from the proliferation of preexisting interlobular bile ducts and ductules.

Primary sclerosing cholangitis is an idiopathic disease characterized by progressive diffuse stricture of extrahepatic and intrahepatic bile ducts. Eighteen patients with end-stage symptoms of primary sclerosing cholangitis were evaluated during a 10-year period from 1976 to 1986. Nine patients presented with disease amenable to intrahepatic cholangiojejunostomy. All patients presented with elevated liver function test results, and six of nine patients had a history of ulcerative colitis. The mean survival after intrahepatic cholangiojejunostomy was 3.9 years (range, 4 months to 10 years). Two of three of the patients with biliary cirrhosis died within 1 year after surgery. Four of nine patients remain alive today, with a mean survival of 4.7 years. For patients with end-stage primary sclerosing cholangitis, intrahepatic cholangiojejunostomy provides effective surgical palliation in those without secondary biliary cirrhosis.

To determine whether portal lymphadenopathy in primary biliary cirrhosis is caused by deposition of lipofuscin pigment in sinus histiocytes and to compare primary biliary cirrhosis with other liver diseases a retrospective study on a consecutive series of 169 livers obtained at transplantation was carried out. There were grouped into eight diagnostic categories: primary biliary cirrhosis (n = 51), primary sclerosing cholangitis (n = 10), extrahepatic biliary atresia (n = 6), chronic rejection (n = 9), cirrhosis (other causes) (n = 38), primary liver neoplasia (n = 21), acute liver disease (n = 20), and retransplantation (other) (n = 14). Lymph nodes were present in 66 specimens. Fifty of these contained granules of lipofuscin pigment. The highest incidence of lymph node enlargement and the largest amounts of pigment were present in cases of primary biliary cirrhosis. A similar pattern of lymph node enlargement was also commonly observed in other chronic cholestatic conditions (primary sclerosing cholangitis, biliary atresia, chronic rejection). Much less pigment was seen in nodes draining livers with non-cholestatic cirrhosis or primary tumours. Nodes were not found in acute liver disease. It is concluded that portal lymphadenopathy associated with lipofuscin is a common finding in various chronic cholestatic liver diseases. The pathogenesis of this lesion is uncertain. Most cases are asymptomatic with enlarged nodes which may be detected only at laperotomy or necropsy and may be wrongly attributed to neoplastic disease. Diagnostically, the finding of large amounts of lipofuscin in enlarged portal lymph nodes is a good indicator of underlying chronic cholestatic liver disease.

In contrast to deficiencies of vitamins A, D and K, little is known of the prevalence, clinical manifestations and mechanisms of vitamin E deficiency in adult patients with cholestasis. We measured serum vitamin E levels in 45 patients with primary biliary cirrhosis, 20 with primary sclerosing cholangitis, 9 with cryptogenic cirrhosis and 12 with alcoholic cirrhosis. To correct for the hyperlipidemia often found in patients with primary biliary cirrhosis and primary sclerosing cholangitis, total serum lipids were measured and vitamin E levels were expressed as the vitamin E/total serum lipid ratio. Serum vitamin A and D levels and prothrombin time were also determined. Six of 45 patients with primary biliary cirrhosis (13%) but none of the patients with sclerosing cholangitis, cryptogenic cirrhosis or alcoholic cirrhosis and subnormal vitamin E/total serum lipids ratios. Vitamin E deficiency was found in two of eight patients with asymptomatic primary biliary cirrhosis. There was no correlation between standard liver biochemical tests, fasting serum cholylglycine and vitamin E levels. Patients with primary biliary cirrhosis and primary sclerosing cholangitis had significantly lower vitamin E/total serum lipids ratios than patients with either cryptogenic or alcoholic cirrhosis. Twenty-three percent of patients with primary biliary cirrhosis were vitamin D deficient and 14% had low vitamin A levels. Two of the six patients with vitamin E deficiency were also deficient in vitamin D, only one was vitamin A deficient and none had prolonged prothrombin time. We also investigated the gastrointestinal absorption of vitamin E in nine patients with primary biliary cirrhosis and normal vitamin E levels as well as in six normal controls.(ABSTRACT TRUNCATED AT 250 WORDS)

As an initial step in testing the hypothesis that immunoregulatory abnormalities are important in the pathogenesis of primary sclerosing cholangitis, we determined the number and percentage of lymphocyte subsets in the peripheral blood of 33 patients with primary sclerosing cholangitis. In these patients, when compared with normal and diseased controls, there was a significant reduction in the total number of circulating T cells because of a disproportionate decrease in Leu-2a (suppressor/cytotoxic) cells. This decrease resulted in a significantly increased ratio of Leu-3a to Leu-2a cells. Patients with cirrhosis had significantly higher Leu-3a/Leu-2a (helper/suppressor) ratios than did noncirrhotic patients; both disease groups, however, had ratios that were significantly higher than controls. The number and percentage of B cells were significantly increased. Alterations in the percentage of B cells correlated significantly with histologic stage and concentrations of gamma globulin, serum IgG, and bilirubin. We conclude that these abnormalities are suggestive of a defect in immunoregulation in primary sclerosing cholangitis, which is not secondary to advanced liver disease alone and appears to be independent of chronic ulcerative colitis or obstructive jaundice.
