The seasonal variations in circulating 25-hydroxycholecalciferol (25-HCC) were studied in 102 alcoholics with fatty liver disease without histologic signs of cirrhosis and in 35 patients with alcoholic cirrhosis. The mean levels were compared with those of normal persons. Alcoholics had generally lower 25-HCC values than the controls, particularly in the summer. This was primarily explained by insufficient diet and reduced exposure to sunshine. The ability of the liver to hydroxylate in the 25-position was studied in three groups of alcoholics with 1) fatty liver disease without cirrhosis, 2) compensated cirrhosis, 3) severely incompensated liver cirrhosis. All three groups exhibited a significant increase in serum 25-HCC following the peroral administration of cholecalciferol at a dose of 1 200 U daily for 7 days. Similar rises were seen 7 days after a single injection of 10 000 U cholecalciferol. This indicates a normal intestinal absorption of vitamin D, even in advanced alcoholic liver disease, and is inconsistent with a severely damaged 25-hydroxylation capacity in these patients. Osteomalacia due to impaired liver hydroxylation of vitamin D can hardly explain the increased fracture rate and the decreased bone mass, which have been described in alcoholics.

After 12 days of culture, VX2 carcinoma cells were inoculated into the liver of 16 rabbits; 14 days later, 131I-labeled iodized oil ([131I]-Lp) suspended in lipiodol was injected into the hepatic artery. Selective accumulation of the contrast material in the tumor for an extended time was evident on X-rays and hepatic scintiphotographs. The antitumor effect was remarkable. [131I]-Lp agents warrant further examination for their clinical usefulness. Internal radiation therapy by transcatheter hepatic arterial injection of [131I]-Lp (group A) was evaluated in 9 patients with hepatocellular carcinoma (HCC, tumor stage III or IV) associated with liver cirrhosis (LC) and compared with combination therapy of Lp-TAE (group B) in 18 patients with HCC (tumor stage III or IV) associated with LC. In group A, serum AFP levels dropped rapidly in eight of the nine patients who had an elevated initial level of more than 500 ng/ml. The average reduction in tumor size was 50% in eight cases as determined by computed tomography. Histological examination of one resected liver specimen at 3 months after the third injection of [131I]-Lp revealed microscopic features highly suggestive of a radiation effect in the [131I]-Lp-containing area. The 1-year survival value for patients with HCC was estimated at 49.0% using the Kaplan-Meier method. The survival of patients treated with internal radiation therapy tended to be better than that of those treated with Lp-TAE (P = 0.119).

Tissue plasminogen activator (t-PA) levels in plasma or serum were studied in 416 patients with liver diseases: acute hepatitis (AH, n = 30); fulminant hepatitis (FH, n = 36); chronic inactive hepatitis (CIH, n = 57); chronic active hepatitis (CAH, n = 39); compensated liver cirrhosis (cLC, n = 78); decompensated liver cirrhosis (dLC, n = 84); hepatocellular carcinoma (HCC, n = 64); advanced hepatocellular carcinoma (aHCC, n = 28); and compared with that of a control group (n = 106) of healthy subjects. The t-PA levels showed significant increase in patients with AH, FH, CAH, cLC, dLC and HCC, compared with normal controls. The abnormal rates in t-PA levels (higher than 8.3 ng/ml) for each type of liver diseases were 86.1% in FH, 46.2% in CAH, 50% in cLC, 85.7% in dLC, 67.2% in HCC, and 89.3% in aHCC. t-PA levels tended to be higher in more advanced liver diseases. t-PA levels significantly correlated positively with plasminogen activator inhibitor (PAI-1) in AH, cLC, dLC, HCC and aHCC, and negatively with plasmin alpha 1-plasmin inhibitor complex (PIC), plasminogen (Plg), FDP, AT III and alpha 2-plasmin inhibitor (alpha 2-PI) in dLC, prothrombin time (PT) and fibrinogen (Fbg) in HCC. t-PA levels in patients with FH, CAH and dLC were significantly higher than those in patients with AH, CIH and cLC, respectively. Moreover, the changes of t-PA levels in the clinical courses of various liver diseases revealed that t-PA levels increased sensitively with progression of liver diseases or in advanced liver diseases.(ABSTRACT TRUNCATED AT 250 WORDS)

Hepatocellular carcinoma is endemic in Africa, where in the incidence of the disease in males ranges from 20-100,000 per annum. The tumor tends to occur at a younger age compared to the age of presentation in Europeans or Chinese. The majority of African patients with HCC are HBsAg positive, but HBsAg is more commonly detected in younger vs older patients. Approximately 30% of patients are anti-HCV positive. Both these chronic virus infections may induce disease via the development of cirrhosis. Other environmental factors including carcinogens such as aflatoxin may act as co-factors. Resection rates for hepatocellular carcinoma are low in this population group, and screening for small tumours is not generally undertaken in Africa.

The prevalence of antibodies to hepatitis C virus (HCV) was investigated in 129 patients with chronic liver disease (85 with chronic active hepatitis and 44 with cirrhosis) and 53 patients with hepatocellular carcinoma. The commercially available second generation anti-HCV enzyme immunoassay kit was used. Antibodies to hepatitis C virus were detected in 16.2% of the patients with chronic liver disease and in 15.1% with hepatocellular carcinoma. Of the HCV positive patients in all groups 51.7% were positive for hepatitis B virus (HBV) markers indicating present or past infection. Prevalence of HBV markers in all the three groups (CAH, cirrhosis and HCC) was higher as compared with anti-HCV prevalence. These results suggest that HCV infection may not be a major cause of chronic liver disease and hepatocellular carcinoma in India and indicate the presence of other aetiological agents.

High-differentiated hepatocellular carcinoma (h-d HCC) is a not frequent hepatic tumour but its outcome may be beneficial when treated properly. Two cases of h-d HCC recognized on the basis of postoperative histopathology are reported. We have discussed the role of fine needle biopsy in distinguishing h-d HCC from liver adenoma, and we have attempted to outline the diagnostic approach in clinically silent hepatic tumours which are not associated with cirrhosis or elevated alfa-fetoprotein plasma level.

PAP technique and rabbit anti-X serum were used to detect the X protein in tumor and nontumor liver tissues from 34 patients with HCC. The positive rate of the X protein in both tissues were 94.1% and 84.4% respectively. Of the 34 patients with HCC, 27 were complicated by liver cirrhosis, in whom 92.6% were X protein positive in liver cells. It was found that almost all of the liver cells adjacent to the tumor tissue showed strong positive staining. The high frequency and predominant expression of X protein in HCC and liver cirrhosis tissues indicated that X protein may play an important role in hepatocarcinogenesis. X protein was detected in 17.2% of the patients with CAH, which suggested the risk of transformation from CAH to cirrhosis and/or HCC. X protein was first found in bile duct epithelial cells in 59.4% of the patients with HCC, and 6 of 34 HCC were combined with bile duct carcinoma, and some cancer cells were found positive for X protein. It seems that X protein may also be a potential factor in the oncogenesis of bile duct carcinoma.

To study the relationship between duck hepatitis B virus (DHBV) infection and duck hepatocellular carcinoma (DHCC), histological examination and DHBV DNA hybridization were performed in 875 ducks from three flocks in Qidong County. Among them, 34 suffered from hepatoma, including 23 hepatocellular carcinoma, 8 cholangiocarcinoma and 3 hepatocellular-cholangiocarcinoma. Of the 34 ducks with hepatoma 27 were positive for DHBV DNA in the liver and/or serum. DHBV DNA was demonstrated in neoplastic nodules of 22 ducks. Southern blot analysis showed that 13 cases were of the integrated pattern of DHBV DNA in neoplastic nodules. The paratumor tissues of 14 ducks with massive tumor were analysed at the same time. Five cases showed integrated pattern, 4 cases free pattern and the other 4 cases both integration and free pattern of DHBV DNA. The hybridization pattern of DHBV DNA in tumor nodule was different from that in paratumor regions in 11 cases and identical in 3 cases. DHBV antigen was positive in 13 tumor nodules and 21 paratumor tissues in the 34 ducks with hepatic tumor by both victoria blue and orcein stain methods. Advanced liver diseases were found in 30 out of the 34 ducks with hepatoma, including 12 cirrhosis and 18 chronic active hepatitis. In southern blot analysis of 122 DHBV DNA positive Qidong ducks without hepatoma, only free pattern of DHBV was seen, while 44 control ducks from Changchun were negative for DHBV DNA. Neither hepatic tumor nor liver diseases were seen in the control ducks. The results suggest that hepatocellular carcinoma in ducks is similar to that in human HCC. They have a high frequency of viral DNA integrated into the host genome and a liver disease background.

To evaluate the role of IgM specific antibody in the diagnosis and monitoring of the patients with chronic hepatitis C, sera from 114 cases with chronic hepatitis C and liver cirrhosis were tested. IgM antibody to hepatitis C virus was detected in 40.0% of CAH, as compared with 21.4% of CIH, 17.4% of LC, 20.0% of LC with HCC. IgM antibody was also detectable in cases with high level of s-ALT. Patients with positive this antibody have high titer of IgG antibody to hepatitis C virus. In summary, testing for this antibody may be useful to evaluate the recurrence or disease activity and may also be helpful in IFN therapy.

Some complications of liver transplantation appear as aspecific clinical and blood test abnormalities; others--e.g., hepatic artery thrombosis in the immediate postoperative period and stenosis of the biliary anastomosis before T-tube removal--require early diagnosis. These considerations justify the need of frequent radiologic examination in both the complicated course and the follow-up. The authors report their experience in 59 adult patients submitted to liver transplantation for irreversible liver disease in advanced stage (49 with cirrhosis, 10 with HCC; 5 with cholestatic hepatopathy; 3 with fulminant hepatitis; 1 with Budd-Chiari syndrome; 1 with metastatic APUDoma). Two hundred and sixty-three radiological examinations were performed (Doppler US, CT, angiography and cholangiography) which showed numerous early and delayed complications: 13 of them were treated with interventional radiology maneuvers (US-or CT-guided percutaneous drainage of fluid collections, biliary drainage, bilioplasty, arterial transcatheter embolization). Our results demonstrate that diagnostic and operative radiology are essential for the success of liver transplantation; integrated imaging is particularly important in the diagnosis of complications, while interventional radiology techniques can be usefully employed in their treatment.
