We assessed a clinical usefulness of JSCC (Japan Society of Clinical Chemistry) recommended method for the measurement of serum alkaline phosphatase. The recommended method is completely correlated both in the liver-bone and intestine isoenzymes with Kind-King method recommended by the expert panel of liver function tests in Japanese Society of Gastroenterology. On the other hand, mixed tests of liver-bone and intestine isoenzyme completely show the full recovery at any combinations of both enzymes using indoxylphosphate isoenzyme staining method. These results indicated that the quantitative analysis of blood alkaline phosphatase is possible employing the combination of JSCC recommended and indoxylphosphate staining methods. Employing these combinations, we could effectively assess the pathophysiological significance of intestine alkaline phosphatase appeared in liver cirrhosis and portal hypertension.

The purpose of the work was an assessment of TNF-alpha and Il-6 concentrations in 34 children with diagnosed chronic hepatitis. In all studied patients the values of TNF-alpha and Il-6 concentration were slightly increased. The correlations calculated between TNF-alpha and Il-6 concentrations calculated between TNF-alpha and Il-6 concentrations and laboratory parameters (laboratory indicators of hepatitis activity--AlAT; liver function indicators--prothrombin index, bilirubin concentration, bile acid concentration, alkaline phosphatase activity, anti-pyrin half-life) were non-significant in Spearman non-parametric test (p > 0.005) except for the correlation between albumin and TNF-alpha concentrations. No statistically significant differences of TNF-alpha and Il-6 concentrations were found between groups of patients with active and persistent hepatitis; groups with and without cirrhosis as well as between groups with and without portal hypertension. Normal or slightly increased TNF-alpha and Il-6 concentrations, observed in chronic hepatitis in children should be explained by compensated liver function in such patients.

Nodular regenerative hyperplasia has not previously been reported in patients who have undergone orthotopic liver transplantation. In this report we describe the clinical, biochemical and histologic findings in nine liver transplant recipients in whom nodular regenerative hyperplasia developed between 6 and 144 mo (median, 64 mo) after transplantation. Six of the patients manifested features of portal hypertension (variceal bleeding, ascites, severe intractable peripheral edema), whereas three patients were asymptomatic at the time of diagnosis. All patients had elevated serum alkaline phosphatase (median, 269 IU; range, 159 to 1182 IU) and gamma-glutamyl transferase levels (median, 247 IU; range 104 to 1513 IU). Other liver function tests remained normal. In five patients, earlier biopsies had identified histological features of venous outflow block, consistent with azathioprine hepatotoxicity. All nine patients had been taking azathioprine up to the time of presentation. After withdrawal of azathioprine, liver function tests improved appreciably in five patients and histologic improvement was documented in four of these who underwent follow-up liver biopsies. In the remaining four patients progressive graft failure ensued and all subsequently underwent repeat liver retransplantation. At a certain stage, nodular regenerative hyperplasia, in the context of a liver graft, becomes an irreversible lesion, emphasizing the need for early identification and withdrawal of the agent.

We report on 56 children with sclerosing cholangitis (SC) seen between 1972 and 1992. The first symptoms occurred at a mean age of 3.7 years; 15 infants had neonatal cholestatic jaundice. At diagnosis, cholestatic jaundice was present in 25 children, hepatomegaly in 54, splenomegaly in 41, and ascites in 12. Serum alkaline phosphatase activity was increased in 49 patients and gamma-glutamyltransferase activity in all patients tested. Most often the histopathologic findings were extensive portal fibrosis and neoductular proliferation. Cholangiography showed abnormal intrahepatic bile ducts in all children and abnormal extrahepatic bile ducts in 35 (63%). The children were separated into three groups: (1) those with SC of neonatal onset (27%); (2) those with SC of postneonatal onset associated with another disease (55%)--histiocytosis X in 14 children, immunodeficiency syndromes in 8, chronic inflammatory bowel disease or autoimmune hepatitis in 8, and congenital psoriasis in 1; and (3) those with SC of postneonatal onset without an associated disease (18%). Biliary cirrhosis was present in all but three children after 6 months to 19.3 years of follow-up. Eleven children died of portal hypertension or liver failure, and six died of a complication related to the associated disease. Fifteen children had liver transplantation; 11 of these are alive 6 months to 6 1/2 years later without recurrence of SC. The overall estimated median survival time of children with SC was 10 years from clinical onset. These results indicate that SC should be suspected in all children with a chronic cholestatic disease and increased serum gamma-glutamyl transferase activity, especially when diseases known to be associated with SC are present. The prognosis is poor, but liver transplantation should be considered except in those with severe immunodeficiency syndromes.

Laminin, a glycoprotein synthesised by Ito cells, has been considered a marker of fibrogenesis. The behaviour of laminin and clinical and laboratory data in 83 patients with cirrhosis were studied to find the factors associated with increases in this glycoprotein. There were increased concentrations of laminin in 62.7% of the patients (40% of the Child's A, 64.5% of the Child's B, and 75% of the Child's C categories). Significant differences in laminin concentrations were found between the Child's grades (p = 0.009) and between patients and controls (p < 0.0001). Correlations were found between laminin concentrations and mean corpuscular volume, aspartate aminotransferase, aspartate aminotransferase: alanine aminotransferase ratio, alkaline phosphatase activity, bilirubin and glycocholic acid concentrations, and hypoalbuminaemia--that is, variables related to liver insufficiency and alcohol intake. Moreover, patients with an alcohol intake higher than 100 g/day had higher laminin concentrations than those with a lower intake (p = 0.03). Conversely, there was no significant association with portal hypertension. Multivariate analysis showed that mean corpuscular volume, bilirubin concentrations, and hypoalbuminaemia were independently associated with laminin concentrations. Poor degradation associated with liver insufficiency seems to play an important part in the increase in serum laminin concentrations in these patients.

Among 211 patients who, between 1985 and 1990, underwent liver resection in Kyushu University Hospital, uncontrollable ascites occurred in 53 (25%). A univariate analysis revealed that postoperative death with liver failure occurred more frequently in patients with intractable ascites (p < 0.05). Alanine amino transferase levels were significantly higher in patients with intractable ascites (p < 0.05), but serum bilirubin, alkaline phosphatase and serum albumin levels did not differ significantly. Portal pressure (p < 0.05), the operation time (p < 0.01) and blood loss (p < 0.01) were significantly higher in patients with intractable postoperative ascites. A multiple analysis showed a correlation between the operation time, portal hypertension and postoperative intractable ascites. Postoperative histology revealed that a larger number of patients with cirrhosis had intractable ascites (p < 0.05). We conclude that cirrhosis, portal pressure and operating time are the most important factors related to intractable ascites in the case of hepatectomy. Areas of the liver to be resected should be limited in cirrhotic patients with portal hypertension.

Primary sclerosing cholangitis (PSC) is considered to be rare in India. The aim of the present study was to investigate the incidence, clinical profile and outcome of PSC seen in a tertiary care centre. Over a period of 10 years (July, 1984-June, 1994) 18 patients of PSC were diagnosed at cholangiography (14 patients by endoscopic retrograde cholangiopancreatography, two patients by percutaneous transhepatic cholangiography and two patients by both methods). The presence of secondary causes, such as choledocholithiasis, biliary tract surgery, congenital biliary tract anomalies, cholangiocarcinoma and pancreatic diseases, were excluded. These patients were evaluated retrospectively with respect to their clinical presentation, radiological findings, presence of associated idiopathic ulcerative colitis (IUC), treatment instituted and outcome. The mean (+/- s.d.) age at diagnosis of PSC was 39.0 (+/- 16.1) years with a male:female ratio of 1.57:1. Nine (50%) patients had associated IUC. The diagnosis of the IUC preceded that of PSC in all but one case. Fifteen (83.3%) patients had cholestatic jaundice at presentation, while three (16.7%) patients had asymptomatic rise of alkaline phosphatase. Three (16.7%) patients had recurrent cholangitis and five (27.8%) patients developed portal hypertension during the course of the disease. At cholangiography, intrahepatic radicles were involved in all and extrahepatic radicles in 12 (66.6%) cases. Patients were managed with steroids (n = 7), colchicine (n = 3), ursodeoxycholic acid (UDCA; n = 2) and methotrexate (n = 1), along with symptomatic measures. Mean duration of follow up available in 11 (61%) patients was 20.1 months (range: 1 month-8 years). Four (36.4%) patients died. Steroids and colchicine did not have any effect while the one patient on UDCA and one on methotrexate showed improvement. In conclusion, in India PSC does not seem to be a rare entity. Its clinical profile and outcome are somewhat similar to those seen in Western countries.

A 37-year-old woman who had portal hypertension followed by splenomegaly, developed collateral blood flow of spleno-renal shunt and paraesophageal veins, esophageal varices and further with narrowing of intrahepatic bile ducts shown by endoscopic retrograde cholangiography was described. Liver function was almost normal except the slight elevation of serum alkaline phosphatase and gamma-glutamyl transpeptidase levels. However, endoscopic retrograde cholangiography revealed the narrowing of the intrahepatic bile ducts. The histological examination of biopsied specimen showed no prominent change in portal tracts and bile ducts without cell infiltration or fibrosis in the portal area. This case will be considered as idiopathic portal hypertension complicated by narrowing of the intrahepatic bile ducts.

Although the involvement of the liver is common in systemic amyloidosis (AL), clinical features of hepatic dysfunction and liver chemistry abnormalities are often mild or absent. A mild increase in the serum alkaline phosphatase value is the most common finding. Hypertransaminasemia, hyperbilirubinemia, and portal hypertension with ascites and gastroesophageal varices occur late in the course of the disease and predict a short survival. We describe the case of a 58-year-old woman with AL, whose dramatic and unusual clinical picture, consisting of giant hepatomegaly, hypertransaminasemia, increase in alkaline phosphatase, esophageal varices, and ascites, was rapidly complicated by severe obstructive cholestasis.

Since 1983 large number of people are being encountered with arsenic toxicity due to drinking of arsenic contaminated water (0.05-3.2 mg/l) in 6 districts of West Bengal. Clinical and various laboratory investigations were carried out on 156 patients to ascertain the nature and degree of morbidity and mortality that occurred due to chronic arsenic toxicity. All the patients studied had typical rain drop like skin pigmentation (being inclusion criteria) while thickening of palm and sole were found in 65.5% patients. Other features included weakness (70%), gastro-intestinal symptoms (58.6%), involvement of respiratory system (57.08%) and nervous system (50.6%). Lung function tests showed restrictive lung disease in 53% (9/17) and combined obstructive and restrictive lung disease in 41% (7/17) of patients. Abnormal electromyography was found in 34.8% (10/29) and altered nerve conduction velocity in 34.8% (10/29) of cases. Enlargement of liver was found in 120 cases (76.9%) while splenomegaly in 31.4% cases. Liver function test showed elevated globulin level in 15.8% and alkaline phosphatase in 51.3%, alanine amino transferase (ALT) in 11.8% and aspartate amino transferase (AST) in 27.6% of cases. Evidence of portal hypertension was found in 33.3% patients. Liver biopsy reports of 45 patients showed non-cirrhotic portal fibrosis in 41, cirrhosis in 2 and normal histology in 2 cases. There was no correlation between the quantity of arsenic taken through water and the level of arsenic in hair, nail, liver tissues and the degree of fibrosis. There were 5 deaths of which one had skin cancer. The various non-cancer manifestations which were observed in these patients were much severe than those reported in similar cases in other parts of the world.
