Survival of and hepatoma development in patients with liver cirrhosis.

A follow-up study was made on 75 patients with liver cirrhosis. The patients were divided into 5 groups (discontinued alcoholic group, continued alcoholic group, hepatitis B group, male non-alcoholic non-hepatitis B group, and female non-alcoholic non-hepatitis B group). Hepatoma developed in 50% of the hepatitis B group, but in 1-9% of the other 4 groups. Abstinence did not accelerate the development of hepatoma. As for survival after onset of liver cirrhosis, the 1-4-year survival of the female non-alcoholic non-hepatitis B group and the final (8-year) survival of the hepatitis B group appeared to be lower than that of the other groups. Though the survival of the discontinued alcoholic group was seemingly higher that that of the continued alcoholic group, the difference was small and not significant.

Obstruction of the inferior vena cava in the hepatic portion and hepatocellular carcinoma.

High incidence of hepatocellular carcinoma in patients with obstruction of the inferior vena cava in the hepatic portion (Budd-Chiari syndrome) was previously pointed out by us from the review of Japanese literature of autopsied cases. This was confirmed by the follow-up study of 16 patients with obstruction of the inferior vena cava in the hepatic portion hospitalized in 1958 to 1974. Follow-up information was available on 13 of the 16 patients. Deaths due to hepatocellular carcinoma occurred in 6 patients (46%), and those due to other causes in 4 patients (31%). Three patients were alive. Hepatocellular carcinoma occurred most frequently in the patients who were found to have obstruction of the inferior vena cava at less than 44 years of age and were followed up for more than 10 years.

Serum beta 2-microglobulin in chronic liver diseases.

Serum beta 2-microglobulin was determined in 53 patients with chronic liver diseases. No elevation was shown in fatty liver due to obesity or alcoholism. Serum beta 2-microglobulin was abnormal only in 4% of the patients with chronic hepatitis. Determination of serum beta 2-microglobulin seems not useful for the differential diagnosis between chronic hepatitis and fatty liver due to obesity or alcoholism. Serum beta 2-microglobulin was elevated in 29% of the patients with alcoholic liver cirrhosis, in 41% of those with non-alcoholic liver cirrhosis, and in 75% of those with primary liver carcinoma. The average serum beta 2-microglobulin concentration was significantly higher in non-alcoholic liver cirrhosis than in alcoholic liver cirrhosis. There was a significant correlation between serum beta 2-microglobulin and gamma-globulin concentrations in liver cirrhosis.

Difference of subtypes of hepatitis B surface antigen between asymptomatic carriers and patients with chronic liver diseases.

Subtypes of hepatitis B surface antigen (HBsAg) were studied in 20 asymptomatic HBsAg carriers and 18 HBsAg-seropositive patients with chronic hepatitis or live cirrhosis. Among them 25 were university students. In the male university students, subtypes adw was found to be significantly higher in asymptomatic HBsAg carriers than in patients with chronic hepatitis (p=0.04). The difference in subtypes of HBsAg between male asymptomatic carriers and male patients with liver disease was further confirmed by the combined results of university students and other subjects (p=0.007).

Elevation of glutamic pyruvic transaminase and gamma-glutamyl transpeptidase in obesity.

Study was made of glutamic pyruvic transaminase (GPT), glutamic oxalacetic transaminase (GOT), and gamma-glutamyl transpeptidase (gamma-GTP) in 729 obese subjects in various groups, namely, primary school children, high school children, university students, and outpatients. The incidences of abnormal GPT, GOT, and gamma-GTP in the obese subjects were frequently significantly higher than in the controls. It was most clearly shown in GPT. The incidences of abnormal GPT in the obese females were significantly lower than those in the obese males, but were significantly higher than the controls. Higher incidences of abnormality in the school children were ascribed to the higher degree of obesity in the children. The extent of increase in GPT was considerable. GPT was sometimes higher than 6 times the normal upper limit.

Hepatitis B antigens and antibodies in asymptomatic carriers and in chronic liver diseases.

88% of asymptomatic hepatitis B surface antigen (HBsAg) carriers and 97% of HBsAg positive patients with chronic hepatitis or non-alcoholic liver cirrhosis showed high titers of antibody to hepatitis B core antigen (anti-HBc). A high titer of anti-HBc, thus suggested to be an indicator of persistent hepatitis B virus infection, was found rarely in seronegative patients with chronic hepatitis, non-alcoholic cirrhosis, or alcoholic liver diseases. It was not revealed in idiopathic portal hypertension or Budd-Chiari syndrome. In asymptomatic HBsAg carriers of 20--29 years of age, hepatitis B e-antigen (HBeAg) was significantly more frequently found in males than in females. There were differences in sex ratio, age, and history of blood transfusion between B type and non-B type of chronic hepatitis and non-alcoholic liver cirrhosis.

Alcoholic liver disease in women.

In 1972-1977, 130 patients with alcoholic liver disease (123 men and 7 women) were admitted. A half of the women had occupations which are related with alcohol consumption and a half were housewives. Daily consumption of alcohol in the women was the same as in the men. Duration of excessive drinking was 11.4 years in the women and 17.1 years in the men, but the difference was not statistically significant. Though the difference of the incidence of alcoholic hepatitis in the women (57%) and in the men (27%) was not statistically significant, frequency of ascites was significantly higher in the women (43%) than in the men (7%). Women seem to be more susceptible to severe form of alcoholic liver damage.
