Abnormal liver tests, as well as morphological changes in the liver, are frequent among obese patients. Other frequent disturbances are visceral fat accumulation, insulin resistance, non-insulin-dependent diabetes mellitus (NIDDM), hypertriglyceridemia, and hypertension; these are set of aberrations known as the metabolic syndrome. In order to investigate a possible relationship between the metabolic syndrome and impaired liver status we examined associations between liver tests, metabolic variables (insulin, glucose, and triglycerids), body composition and nutrition in 1,083 men (BMI 28.8-63.8 kg/m2) and 1,367 women (BMI 26.7-68.0 kg/m2) in the ongoing intervention study of Swedish Obese Subjects (SOS). Standard biochemical techniques were used to assess liver status and metabolic variables. Lean body mass (LBM) and masses of visceral and subcutaneous adipose tissue (AT) were estimated by means of computed tomography (CT) calibrated anthropometric equations. In both genders aspartate aminotransferase and alanine aminotransferase were, or tended to be, positively correlated to fasting serum insulin, visceral AT (women), and alcohol intake. In women, the aminotransferases were also correlated with fasting blood glucose. In both genders alkaline phosphatase was, or tended to be, positively associated with visceral AT, insulin (women), and glucose. Bilirubin was negatively correlated to insulin and visceral AT in men and women. Additional multivariate analyses indicated that alcohol had less explanatory power than serum insulin for the examined liver tests, especially among women. These results suggest that pathological liver tests in the obese may represent an expression of the metabolic syndrome.

The aetiology, biochemistry, clinical features and complications of histologically confirmed hepatic cirrhosis in 45 patients (26 females, 19 males) seen at the University Hospital of the West Indies, Jamaica, between 1984 and 1994 are presented. The age range was 1 to 72 years (mean 48 years). Abdominal swelling and weight loss were the commonest symptoms, occurring in 51% and 47% of patients, respectively. Jaundice was a presenting feature in 44%. Hepatomegaly was present in 71% of patients and splenomegaly in 33%. The aetiological factors were: alcohol (36%), bush tea (18%), chronic active hepatitis (11%), drugs (7%), and haemochromatosis (2%). Hepatitis B surface antigen was detected in 2 of 20 patients tested. 24% of the patients also had diabetes mellitus., 29% were anaemic, 29% were thrombocytopenic, 4% were leukopenic, and the prothrombin time was prolonged in 22%. The albumin/globulin ratio was reversed in 71% of the patients. The alkaline phosphatase was elevated in 56%, the aspartate aminotransferase was increased in 58% and the gamma glutamyl transpeptidase in 56%. 56% of the patients had macronodular cirrhosis; the liver showed a micronodular pattern in 18%; 7% had biliary cirrhosis; 7% chronic active hepatitis with cirrhosis; and 13% showed a mixed macro-micronodular pattern. Ascites and fluid overload developed in 44% of the patients. Hepatic encephalopathy occurred in 18% and upper gastrointestinal bleeding in 18%.

Nonalcoholic steatohepatitis (NASH) is the term used for a common form of fatty liver presenting in adults with varied clinical manifestations. The most common presentation is asymptomatic elevation of liver enzymes (AST or SGOT and ALT or SGPT), which can be discovered incidentally in the course of an annual checkup, life insurance examination, or as part of surrogate screening before blood donation. At the other end of the clinical spectrum is the patient with complications from cryptogenic cirrhosis, who also shows a lack of evidence of alcohol as an etiological factor in pathogenesis. Clinical associations of probable relevance include gender (female), obesity, diabetes, and hyperlipidemia, but many patients do not conform to any of these stereotypes (e.g., young men of normal weight with normal fasting glucose and lipid levels). Liver biopsy confirms the diagnosis of NASH, the association of steatosis with an inflammatory response being the sine qua non for the condition and "creeping fibrosis" being a variable but possibly sinister feature. Newer imaging techniques may provide convincing evidence of steatosis, but they give little insight into ongoing fibrosis, and liver biopsy therefore remains the gold standard. The mainstay of treatment remains judicious weight loss coupled with positive dietary advice, including the ingestion of adequate but not excessive vitamins. After initial encouraging data. the assessment of ursodeoxycholic acid currently being studied under randomized controlled conditions is eagerly awaited.

It has been reported that cytokeratin 19 fragment (CYFRA 21-1) is superior to tissue polypeptide antigen (TPA) as a tumor marker, although there is a high correlation between CYFRA 21-1 and TPA levels in patients with lung cancer. We investigated correlations between these tumor markers in patients with non-malignant diseases. Marked correlations were found between CYFRA 21-1 and TPA levels in healthy subjects (n = 31), non-insulin-dependent diabetes mellitus (n = 160) and hemodialysis patients (n = 83) (range of r-value = 0.90-0.93, P < 0.0001). However in liver cirrhosis patients (n = 36), only a weak correlation was found (r = 0.39, P < 0.0001) and there were correlations between only TPA and both aspartate aminotransferase and alanine aminotransferase levels (r2 = 0.48 and 0.36, P < 0.0001). The elevated TPA levels in liver cirrhosis patients may be related to the decreased specificity of TPA as a tumor marker.

The determination of aminotranferases levels is very useful in the diagnosis of hepatopathies. In recent years, an elevated serum ALT level in blood donors has been associated with an increased risk of post-transfusion hepatitis (PTH). The purpose of the study was to research the factors associated with elevated ALT levels in a cohort of voluntary blood donors and to evaluate the relationship between increased ALT levels and the development of hepatitis C (HCV) infection. 166 volunteer blood donors with elevated ALT at the time of their first donation were studied. All of the donors were questioned about previous hepatopathies, exposure to hepatitis, exposure to chemicals, use of medication or drugs, sexual behaviour, contact with blood or secretions and their intake of alcohol. Every three months, the serum levels of AST, ALT, alkaline phosphatase, gamma glutamyl transpeptidase, cholesterol, triglyceride and glycemia are assessed over a two year follow-up. The serum thyroid hormone levels as well as the presence of auto-antibodies were also measured. Abdominal ultrasound was performed in all patients with persistently elevated ALT or AST levels. A needle biopsy of liver was performed in 9 donors without definite diagnostic after medical investigation. The presence of anti-HCV antibodies in 116 donors were assayed again the first clinical evaluation. At the end of follow-up period (2 years later) 71 donors were tested again for the presence of anti-HCV antibodies. None of donors resulted positive for hepatitis B or hepatitis C markers during the follow-up. Of the 116 donors, 101 (87%) had persistently elevated ALT serum levels during the follow-up. Obesity and alcoholism were the principal conditions related to elevated ALT serum levels in 91/101 (90.1%) donors. Hypertriglyceridemia, hypercholesterolemia, hypothyroidism and diabetes mellitus also were associated with increased ALT levels. Only 1/101 (0.9%) had mild chronic active non A-G viral hepatitis and 3/101 (2.9%) had liver biopsy with non-specific reactive hepatitis. The determination of ALT levels was not useful to detect donors infected with HCV at donation in Brazil, including the initial seronegative anti-HCV phase.

Liver and biliary ultrasonographic findings were studied in 217 asymptomatic obese women [mean age 35.0 +/- 8.3 years, range 15 to 57; mean body mass index (BMI, weight/height2) 40.7 +/- 6.9 kg/m2, range 30.3-71.9] from the Obesity Outpatient Clinic of the Professor Edgard Santos University Hospital. The women underwent an oral glucose tolerance test and were divided into two groups: 21 diabetic obese women plus 25 glucose intolerant (group I); and 171 non-diabetic obese women (group II). Ultrasonography (US) was performed on a Siemens Sonoline SL2 apparatus with a 3.5 MHz transducer. Plasma glucose levels and biochemical tests were determined by the enzymatic method. The frequency of liver US abnormalities was similar in both groups (52.2% of group I and 47.8% of group II). Steatosis was found in 34.8% of group I and 32.2% of group II; steatosis associated with hepatomegaly in 17.4% of group I and 10.5% of group II; and hepatomegaly in 4.1% of group I and absent in group II. Serum cholesterol, HDL-cholesterol, triglycerides, and liver function tests, including aspartate aminotransferase, alanine aminotransferase and gama-glutamiltranspeptidase levels, were similar in both groups. However, triglycerides, uric acid and gamaglutamyl transpeptidase levels were higher in the diabetic and glucose-intolerant group. The frequency of asymptomatic gallstones was higher in group II than group I (24.4% vs 11.7%, p < 0.04). It is suggested that liver and biliary US should be included in the evaluation of all obese women, even when asymptomatic.

Preoperative portal vein embolization (PVE) was performed in 84 patients before extensive liver resection for various diseases. By the criteria of liver volumetric determination, some patients were candidates for PVE, whereas others were not, even though the same surgical procedure, such as extended right lobectomy (ERL), was scheduled. PVE using gelatin sponge powder induced hypertrophy in the nonembolized lobe (0%-171%; median, 30%) and proportional atrophy in the embolized lobe in 2 weeks without eliciting any major inflammatory or necrotic reaction, as evidenced histologically and by the minimal elevations in the serum aspartate transaminase (AST) and alanine transaminase (ALT) values. Alterations in the total bilirubin level and prothrombin time were also insignificant and transient, indicating that hepatocyte functions were not impaired by PVE. Not all patients who undergo PVE proceed with the scheduled hepatic resection procedure, so it is a great advantage that gelatin sponge causes minimal damage compared with other embolizing materials such as cyanoacrylate and absolute ethanol, which have been reported to induce an inflammatory reaction or histological alteration. Our multiple regression analysis showed that three factors, diabetes mellitus, a high total bilirubin level at the time of PVE, and being male, each reduced the extent of hypertrophy in the nonembolized lobe (r2 =.30). By contrast, cholestasis appeared to accelerate the process of atrophy in the embolized lobe (r2 =.16). In conclusion, PVE by gelatin sponge powder is a safe and effective preoperative maneuver that induces hypertrophy of the section of the liver that will remain after partial hepatectomy.

About 50 mg of silver leaf (metallic silver) was given daily by mouth to 30 healthy volunteers for 20 days. A statistically significant hypophospholipidemic, hypotriglyceridemic, hypocholesterolemic and hypoglycemic effect was observed. This was accompanied by a less marked fall in total lipids and significant rise in HDL-cholesterol. In addition, a decrease in plasma enzymes - alkaline phosphatase (ALP), glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), creatine phosphokinase (CPK), gamma glutamyl transpeptidase (GGT) and lactate dehydrogenase (LDH) was noted. This was statistically significant for all enzymes except CPK. The safety of ingested silver foil is indicated by absence of pathology in urine and unaltered levels of protein and albumin in the plasma. These observations suggest that silver could be beneficial in conditions like diabetes mellitus, obesity and atherosclerosis.

A 38-year-old otherwise healthy man presented with hepatic failure (aspartate aminotransferase of 7212 U/L, alanine aminotransferase of 6629 U/L, total and direct bilirubin of 10.7 mg/dL) and acute renal failure (creatinine of 11.6 mg/dL and blood urea nitrogen of 42 mg/dL), which required hemodialysis when the creatinine increased to 21 mg/dL, with a blood urea nitrogen of 115 mg/dL, and the patient became oliguric. On admission, this patient also had a lipase of 1833 U/L, amylase of 211 U/L, glucose of 210 mg/dL, and reactive IgM antibody for acute hepatitis A. The hepatitis and acute renal failure resolved in 3 months, but this patient continues to have type II diabetes mellitus 7 years after the hepatitis A infection. This case illustrates that hepatitis A infection may be severe with liver failure, acute renal failure, and permanent diabetes mellitus as sequale of this infection.

Urinalysis was carried out in 231 inpatients with alcohol dependence syndrome (215 males and 16 females). Fifty-nine patients (25.5%) showed proteinuria, 97 (42.0%) showed glucosuria, and 62 patients (26.8%) showed hematuria on admission. A total of 135 out of 231 patients (58.4%) showed abnormal urinalysis. Proteinuria was related to high blood pressure, high serum glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, lactate dehydrogenase, uric acid, and triglyceride levels, and high urinary amylase concentration. Glucosuria was related to high serum glutamic-oxaloacetic transaminase concentration and a history of gastrectomy. Hematuria was related to high age and high urinary amylase levels. By chi-square test, there was a significant correlation between proteinuria and hematuria (p < 0.001) and between hematuria and glucosuria (p < 0.001), but no correlation was found between proteinuria and glucosuria. The incidence of diabetes mellitus was 10.8% (25 out of 231 patients), but transient hyperglycemia was observed in some patients without diabetes mellitus on admission. Elevated hemoglobin A1, hemoglobin A1c, and fructosamine concentrations were observed in patients with either impaired glucose tolerance or transient hyperglycemia, which suggested the presence of persistent hyperglycemia before admission. On discharge, only 12 out of 198 patients (6.1%) showed abnormal urinalysis. We report that heavy ethanol consumption induces transient abnormal urinalysis results in Japanese alcoholics.
