In the course of 4 years, among 11,738 admissions there were 245 (2.08%) patients with cholestasis (106 women and 139 men). Intrahepatic cholestasis (i.c.) was detected in 46.5%, and extrahepatic (e.c.) in 53.5%. The most frequent cause of i.c. were alcoholic and nonalcoholic chr. liver disease (fatty liver, chr. hepatitis, cirrhosis) (37% and 30%), acute viral hepatitis (15%) and toxic liver injury (14%) respectively. The causes of e.c. were: choledocholithiasis (44%), cancer of the pancreatic head (15%), cancer of gallbladder and extrahepatic ducts (12%) and cancer of liver (10%). The causes of c. were benigne, in 78.2%, while malignant neoplasms were present in 21.8%. Out of the multitude of laboratory tests two appeared particularly significant: glut, transpeptidase was pathologic in 81% of alcoholic liver disease, in 62% of the cases with obstructive jaundice and in 27.7% of malignant neoplasms. LX-lipoprotein examined in 52 patients was positive in 24% of i.c., and 60% of e.c. Proliferation of bile ducts was the most frequent finding in surgical liver biopsies in choledocholithiasis cases.

The activity of prolyl hydroxylase was measured in liver tissue obtained from a small series of patients with a variety of liver disease. Enzyme levels were marginally elevated in patients with fatty liver and viral hepatitis, conditions not normally associated with progressive fibrosis. In some patients with alcoholic hepatitis and in all patients with cirrhosis and chronic active hepatitis, there was a marked increase in enzyme activity. Patients with conditions characterised by high liver prolyl hydroxylase levels showed histological evidence of extensive hepatic fibrosis and also significant increases in the serum values of glutamate dehydrogenase and gamma-glutamyl-transpeptidase. Prolyl hydroxylase activity was not detected in serum.

Blood parameters, feed intake and milk yield were determined in 53 cows with a left displacement of the abomasum (LDA) on the day of surgery (ds; laparotomy and omentopexy) and during the following four days (d1-d4). Using histological methods severe (group SF), moderate (group MF) or no/mild (group NF) fatty liver was found in 32%, 40% and 28% of the patients, respectively. Moderate and severe fatty liver were found almost exclusively in cows in the first three weeks post partum. Post surgery, feed intake and daily milk yield increased steadily in cows of the NF- and MF-group; in cows suffering from severe fatty liver feed intake remained low (p < 0.05). On ds, mean serum levels of nonesterified fatty acids (NEFA), beta-hydroxybutyrate (BHB), total bilirubin, aspartate aminotransferase (ASAT), gammaglutamyl transpeptidase (GGT) and glutamic dehydrogenase (GLDH) in SF-cows were significantly (p < 0.05) higher and values of cholesterol significantly lower (p < 0.05) as compared to the NF- and MF-group; no significant differences were found between the groups in mean serum glucose concentrations. In the four day period following surgery, in all groups mean serum levels of ASAT, GGT, GLDH and cholesterol remained nearly unchanged, whereas total bilirubin, NEFA, BHB and glucose decreased significantly (p < 0.05). Apart from LDA, 55% of the patients were suffering from mastitis, endometritis or lameness. Within three weeks post surgery, 3 cows of the SF-group and 1 cow of the MF-group developed recumbency and liver coma, and were culled for that reason. In conclusion, post surgical convalescence of cows with LDA is clearly related to disturbances of energy metabolism and fatty liver. Therefore, successful treatment of cows suffering from LDA requires the effective treatment of excessive lipomobilization, ketosis and fatty liver along with the immediate surgical correction of LDA.

The prevalence of a mutation of the codon for tryptophan 64 to arginine (Trp64Arg) in the beta3-adrenergic receptor gene was investigated by genotyping 261 Japanese subjects. The allelic frequency of this mutation was 0.18. Subjects with the homozygous W64R mutant alleles had a significantly higher prevalence of fatty liver, BMI, serum gamma-glutamyl transpeptidase, and serum leucine amino transpeptidase levels than those without the mutation. Individuals with this mutation also showed a higher fasting blood glucose level than those without this mutation. However, the prevalence of diabetes mellitus was no different between the three groups. These results suggest a potential association of the Trp64Arg mutation with higher morbidity of fatty liver and mild glucose intolerance.

The validity (sensitivity and specificity) of annual liver function tests, determined by assaying blood levels of aspartate aminotransferase, alanine aminotransferase and gammaglutamyl transpeptidase, was evaluated using the results of health checkups of male bank workers. The specificity of each liver function test to detect persons with fatty liver, excess alcohol users, and hepatic virus carriers, diagnosed respectively by ultrasound, detailed inquiry, and virus marker tests, was always higher than 80%, except for alanine aminotransferase in excess alcohol users (63.5%). However, the highest sensitivity to detect virus carriers was alanine aminotransferase to detect HCV antibody-positive workers, but it was only 45.5%. The highest sensitivity of the liver function tests to detect excess alcohol users in obese subjects was only 33.3%. The highest sensitivity by liver function tests to detect fatty liver was 35.7% which was inferior to that of the body mass index. These results indicate that the liver function tests mandated in the workplace periodic health checkups in Japan exhibit very low sensitivity for the detection of any of the proposed target clinical conditions.

To determine whether the current liver screening program for fatty liver has sufficient scientific evidence to justify its continued implementation. The liver screening program to detect fatty liver was performed on 411 Japanese workers utilizing serum aspartate aminotransferase (ALT), alanine aminotransferase (AST), and gammaglutamyl transpeptidase (gamma-GTP). Based on the preceding studies, subjects with viral and alcohol hepatitis were excluded from the evaluation. The diagnosis of fatty liver was based on ultrasound findings. The program was evaluated by efficacy and effectiveness; efficacy was measured according to the receiver operating characteristic (ROC) curves in comparison with the Body Mass Index (BMI). Effectiveness, based on the efficacy determinations, was assessed by means of the positive predictive value (PPV) test performance, the disease characteristics, and the program price. The diagnostic performances of ALT and BMI were nearly acceptable but far from excellent. The areas under the curves of the two indices were 0.69 and 0.63, respectively and these were statistically equivalent. The PPV ranged from 15 to 28% where the prevalence of fatty liver was 12.3%. The price of the program was estimated at US 4 dollars per person based on the medical reimbursement fee rate. The efficacy of the liver screening program was found to be insufficient and BMI monitoring may provide a more suitable and inexpensive alternative. Furthermore, the effectiveness of the program is open to question, considering the generally benign prognosis of the disease in the absence of any accompanying morbid conditions and the high price of the program.

Diabetes mellitus has been reported to have an increased prevalence and to be associated with more severe fibrosis in patients with chronic hepatitis C. We evaluated the prevalence of diabetes mellitus in patients with chronic hepatitis B or C as well as the possible association between presence of diabetes and extent of liver fibrosis. In total, 434 consecutive patients with histologically documented hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (n = 174) or chronic hepatitis C (n = 260) were studied. The relationships of diabetes and epidemiological, somatomorphic, laboratory and histological patient characteristics were evaluated. Liver histological lesions were blindly evaluated according to the Ishak's classification. Diabetes was present in 58 (13%) patients, without any difference between those with chronic hepatitis B (14%) or C (13%). Diabetes was observed significantly less frequently in patients with fibrosis score 0-2 (7.7%) than 3-4 (10.4%) than 5-6 (29.2%) (P < 0.001). The presence of diabetes was independently associated with higher gamma-glutamyl-transpeptidase (GGT) levels and more severe fibrosis or presence of cirrhosis (P < 0.001) as well as with presence of hepatic steatosis and increased serum triglycerides levels (P < 0.02). In the noncirrhotic patients, diabetes was significantly associated with older age and higher GGT levels, but not with the extent of fibrosis. In conclusion, diabetes mellitus is observed in more than 10% of patients with either HBeAg-negative chronic hepatitis B or chronic hepatitis C. The presence of diabetes is strongly associated with more severe liver fibrosis, but such an association may be related to the high prevalence of diabetes in patients with cirrhosis.
