The seroepidemiology of HBV and HCV infections in the patients with acute and chronic liver diseases in Jakarta was investigated. The sera from 141 cases with
acute hepatitis
, 176 liver cirrhosis and 70
hepatocellular carcinoma
(
HCC
) were examined. Anti-HA IgM, HBsAg, anti-HBc IgM and anti HCV (Ortho) were detected by Elisa method. In
acute hepatitis
, 83 cases (58.9%) out of 141 cases were hepatitis A and 9 cases (6.4%) hepatitis B. The others were diagnosed non-A, non-B (NANB) hepatitis and anti-HCV in 4 cases (11.8%) out of 34 cases with NANB hepatitis was positive. The low prevalence of anti-HCV in acute NANB hepatitis seems to be due to inadequate date of serum sampling. HBsAg and anti-HCV in liver cirrhosis were positive 36.5% and 73.9% respectively, including 22.7% of double infection. HBsAg and anti-HCV in
HCC
were 58.6% and 34.2%, including 17.1% of double infection. In 16.7% fo chronic liver disease (liver cirrhosis and
HCC
), neither HBsAg nor anti-HCV were detected.

A survey was performed to investigate HBV and HCV infection in Ujung Pandang. The total number of subjects was 406; 196 blood donors, 78 cases of
acute hepatitis
, 43 of chronic hepatitis, 58 of liver cirrhosis and 31 of
hepatocellular carcinoma
cases. HBsAg, anti-HBs and anti-HBc as HBV markers and anti-HCV (ELISA, Ortho) as an HCV marker were tested. Positive rates of HBsAg and anti HCV among blood donors were 7.1% and 3.1% respectively, and there was no significant difference among age groups. Donors negative for all viral markers accounted for 21.4%. Of
acute hepatitis
cases, 18 (23.1%) cases were hepatitis A and 8 (10.3%) cases were hepatitis B, one case of which was considered to be double infection. Acute exacerbation cases of HBV carriers were 16 (20.5%), of which 6 cases were positive for HCV antibody. Those diagnosed non-A, non-B hepatitis were 37 (47.4%), of which 3 cases where positive for HCV antibody. Blood samples from all of
acute hepatitis
cases were obtained within 1 week after onset of the disease, thus, it was not possible to accurately assess prevalence of hepatitis C. Positive rates on HBsAg among chronic hepatitis, liver cirrhosis and
hepatocellular carcinoma
were 25.4%, 32.8% and 35.5% respectively, while those for HCV antibody were 16.3%, 43.1% and 35.5% respectively. Positive rates of HBsAg and HCV antibody for overall chronic liver diseases were 31.1% and 32.6%, and 14 (10.6%) were positive for both markers.

A total of 545 serum samples were consecutively collected from patients with
acute hepatitis
, chronic hepatitis, liver cirrhosis,
hepatocellular carcinoma
, chronic hemodialysis and voluntary blood donors to study the seroepidemiology of HBV and HCV infection in Jakarta. Fourteen out of 243 or 5.8% samples from blood donors were HBsAg-positive, while HCV-antibodies (anti-C100 and/or anti-CP9 and/or anti-CP10) positivity rate was found in 59 out of 243 or 24.3%. Out of 91 donors aged 29 years or younger, 15 (16.5%) donors turned positive for HCV-antibody (-ies), while out of 152 donors aged 30 years or above, 44 (28.9%) donors were anti-HCV-positive, showing a higher HCV-antibody prevalence among higher age group. Among 88
acute hepatitis
patients, 33 (37.5%) cases, 10 (11.4%) cases, 15 (17.0%) cases and 30 (34.1%) cases were diagnosed as hepatitis A, hepatitis B, acute exacerbation of HCV carriers, and NANB hepatitis respectively. HCV-antibodies were found in 15 (45.5%) of hepatitis A cases and 6 (40.0%) of acute exacerbation of HBV carrier cases, but found only in 9 (30.0%) of acute NANB hepatitis cases. Positivity rates of HCV-antibodies among 23 chronic hepatitis, 80 liver cirrhosis and 64
hepatocellular carcinoma
cases were 78.3%, 75.0% and 65.6% respectively, while 30.4%, 30.0% and 45.3% of the respective groups were positive for HBs antigen. Among 47 hemodialysis cases, 97.9% and 6.4% were positive for HCV antibodies and HBs antigen respectively. It was concluded that: (1) HBV infection rate is high among blood donors and patients with acute and chronic liver diseases. (2) HCV infection rate is high among blood donors.(ABSTRACT TRUNCATED AT 250 WORDS)

Tissue plasminogen activator (t-PA) in plasma obtained from patients with
acute hepatitis
, chronic hepatitis, liver cirrhosis,
hepatocellular carcinoma
, drug-induced intrahepatic cholestasis, obstructive jaundice, fulminant hepatitis or disseminated intravascular coagulation (DIC), was analysed chromatographically. Liver disease cases showed a new peak (peak C) on HPLC fractionation. The protein of peak C had a lower molecular weight than ovalbumin. Lysine- and zinc- chelating affinity chromatography revealed that the peak C consist with the light chain (L-chain) of t-PA. The L-chain was also found in patients with DIC, but disappeared after improvement of DIC. Therefore, it was suggested that appearance of the L-chain would be related to acceleration of secondary fibrinolysis in plasma. The L-chain was especially high in plasma obtained from patients with decompensated liver cirrhosis. These results indicated that high increase of the L-chain in cases of severe liver disease may be due to either impaired clearance of t-PA in the liver or secondary hyperfibrinolysis accompanied by DIC. We concluded that determination of the L-chain of t-PA may contribute to clarify the mechanism of hyperfibrinolysis in liver diseases.

Previous studies have demonstrated that plasma tissue plasminogen activator (t-PA) level was elevated in patients with liver disease. In this study, t-PA antigen levels were investigated in patients with
acute hepatitis
(AH; N = 12), chronic hepatitis (CH; N = 8), compensated liver cirrhosis (CLC; N = 40), decompensated liver cirrhosis (DLC; N = 23) and
hepatocellular carcinoma
(
HCC
; N = 35). The increased t-PA levels (higher than 14 ng/ml) were found in 33% (4/12) of AH on the early hospital days, 25% (2/8) of CH, 45% (18/40) of CLC and 91% (21/23) of DLC, and 60% (21/35) of Hcc cases. In patient with LC, the correlations between t-PA levels and serum total bilirubin (T.Bill) and hepatic synthetic functions were investigated. The results were that the t-PA levels correlated positively with T. Bil and negatively with liver synthetic functions such as albumin, protein C and choline-esterase, indicating that t-PA increased almost in proportion to the deterioration of hepatic function. Serial determination of t-PA in patients with
HCC
treated by transcatheter arterial embolization (TAE) revealed that TAE failed to normalize the t-PA levels. In one case of
HCC
complicated with disseminated intravascular coagulation (DIC), t-PA showed a marked increase at acute phase of DIC and subsequent decrease after the successful treatment for DIC by gabexate mesilate (FOY) infusion. These results suggest that increased t-PA in liver disease is due mainly to deterioration of hepatic function, and that secondary fibrinolytic state, such as DIC, is also a contributing factor.

Hepatitis B infection and its sequelae constitute a significant public health problem in the United States. It is estimated that 300,000
acute hepatitis
B infections occur each year, with about 25% accompanied by both clinical illness and jaundice. Some infections become chronic and ultimately may cause development of liver cirrhosis or primary
hepatocellular carcinoma
. The risk of chronicity is especially great with infections that occur in infancy. Highly effective vaccines comprised of purified hepatitis B surface antigen (HBsAg) particles are now available for the prevention of hepatitis B infection. A first-generation vaccine utilized HBsAg derived from the plasma of infected persons; this has now been replaced by two similar vaccines that incorporate HBsAg produced by genetically engineered strains of the common bakers' yeast, Saccharomyces cerevisiae. Improved use of vaccine is needed to reduce and ultimately eliminate hepatitis B infection. Vaccination already is recommended for persons recognized to be at increased risk of exposure to virus-containing blood or other body fluids (e.g., infants born to carrier mothers, household or sexual contacts of carriers); however, mass vaccination of adolescents and infants is needed to interdict effectively a majority of all exposures to the hepatitis B virus.

The present study was undertaken to elucidate clinicopathological findings and operative results of
HCC
with HB-associated cirrhosis, compared with those in
HCC
patients with alcoholic and post-transfusion cirrhosis. The number of the HBV group was 26 cases, consisting of 17 in sAg(+), 4 in eAg(+) and 5 in eAb(+) subgroups. The number of the post-transfusion group was 7 and that of alcoholic group was 12. A high incidence of hypersplenism and esophageal varix in the eAg(+) subgroup was found. ICG R15 was the highest, KICG and ICG Rmax were the lowest in the eAg(+) subgroup. The mean diameter of tumors was the largest, 6.6 +/- 3.9 cm, in the sAg(+) subgroup and was the smallest, 2.2 +/- 1.7 cm, in the eAg(+) subgroup. The incidence of postoperative jaundice, hyperammoninemia and live dysfunction were the highest in the sAg(+) and eAg(+) subgroup. One and three-year survival rate were 76.9% and 48.1% in the sAg(+) subgroup, 60.0% and 30.0% in the eAb(+) subgroup, and the one-year survival rate in the eAg(+) subgroup was 50.0%. The three-year survival rate could not be calculated because 3 years had not passed since the operation. The prognosis was the poorest in the HBV group among all groups. This study suggests that in HBV-associated cirrhosis, hepatectomy might induce "acute on chronic" changes (
acute hepatitis
and fulminant hepatitis). Therefore we should select operative procedures by considering surgical risk and the etiology of liver cirrhosis in hepatectomy.

Forty antiviral compounds were screened for inhibitory effect on hepatitis A virus (HAV) antigen expression in the human
hepatoma
cell line PLC/PRF/5. Ribavirin, amantadine, glycyrrhizin, and pyrazofurin were selected in this screening test and were studied further. The selectivity indices of these four compounds, calculated as the ratio of 50% cytotoxic dose (determined by the trypan blue exclusion and by inhibition of [3H] leucine incorporation) to the 50% effective dose (determined by the viral antigen expression), were 4.6 and 3.0 with ribavirin, 5.3 and 5.9 with amantadine, 15.2 and 16.9 with glycyrrhizin, and 45.4 and 74.6 with pyrazofurin. All four compounds resulted in concentration-dependent reductions of HAV antigen expression and HAV infectivity. Ribavirin, amantadine, pyrazofurin, and glycyrrhizin emerged, from the present study, as promising candidates for chemotherapy of
acute hepatitis
A.

To clarify the relationship between hepatitis C virus infection and the development of
hepatocellular carcinoma
as sequelae of non-A, non-B posttransfusion hepatitis, 231 patients with chronic non-A, non-B hepatitis (96 with chronic hepatitis, 81 with cirrhosis and 54 with
hepatocellular carcinoma
) were analyzed for antibody to hepatitis C virus and were compared with 125 patients with chronic hepatitis B (50 with chronic hepatitis, 46 with cirrhosis and 29 with
hepatocellular carcinoma
). Antibody to hepatitis C virus was detected in 89.6%, 86.4% and 94.4% of patients with non-A, non-B hepatitis-related chronic hepatitis, cirrhosis and
hepatocellular carcinoma
, respectively, compared with 6%, 17.4% and 34.5% with similar diseases related to hepatitis B. A history of transfusion was documented in 52%, 33% and 42% of anti-hepatitis C virus-positive cases of chronic hepatitis, cirrhosis and
hepatocellular carcinoma
. The mean intervals between the date of transfusion and the date of diagnosis of anti-hepatitis C virus-positive chronic hepatitis, cirrhosis and
hepatocellular carcinoma
were 10, 21.2 and 29 yr, respectively. In 21 patients with transfusion-associated
hepatocellular carcinoma
, anti-hepatitis C virus was present in each serial sample available for testing, including samples obtained up to 14 yr before the diagnosis of
hepatocellular carcinoma
. These data suggest the slow, sequential progression from
acute hepatitis
C virus-related non-A, non-B hepatitis through chronic hepatitis and cirrhosis to
hepatocellular carcinoma
and support a causal association between hepatitis C virus and
hepatocellular carcinoma
.

The activities of serum malate dehydrogenase (MDH) and its mitochondrial isoenzyme (MDHm) were studied in sera of patients with liver disease. They proved to be more useful than those of aspartate aminotransferase (AST) and its mitochondrial isoenzyme for detection of
hepatocellular carcinoma
and acute circulatory failure, and for estimation of the severity of
acute hepatitis
. The N/T value measuring system, which is adaptable for autoanalysis and allows simultaneous determination of activities depending on NAD and thionicotinamide adenine dinucleotide (thio-NAD), yields both the total activity of MDH and the N/T value which was correlated significantly with MDHm/MDH (r = 0.748). Assay of MDH and its mitochondrial isoenzyme in association with the N/T value measuring system seems to be more useful and less time consuming for estimation of the severity of liver diseases than that of AST and its mitochondrial isoenzyme.
