In a collection of 3,571 patient's files admitted in the University Teaching Hospital and the Yaounde General Hospital, we studied 27 patients suspected of chronic pancreatitis. 20 patients with calcified chronic pancreatitis benefited from a detailed history, physical examination and a complete paraclinical work-up. From the data collected, chronic alcoholism seemed to have been the main aetiology. Industrial beer from barley alone and/or associated with other traditional liquors was most consumed. The majority of patients were heavy alcoholics and daily consumption varied from 75 to 124 g of pure alcohol. The natural history of the disease and physical examination were identical to that observed in the western countries. Associated pathology was observed in 10% of the patients. This included peptic ulcer disease, cirrhosis and bile stones. Complications included diabetics, obstructive jaundice, and malabsorption syndrome. As a conclusion, chronic pancreatitis is a pathology whose prevalence seems to be progressing constantly.

Phase II study of 99mTc-DTPA-galactosyl human serum albumin (99mTc-GSA), a new radiopharmaceutical which binds to the asialoglycoprotein receptors on the hepatocytes, was performed in 81 patients with liver diseases to validate its safety and possibility for the evaluation of hepatic function. None of adverse reactions, abnormal clinical laboratory findings and anti-99mTc-GSA antibody production due to 99mTc-GSA was recognized. Immediately after the injection of 99mTc-GSA, the dynamic data and serial hepatic images were obtained for 60 min. The indices for blood clearance and liver accumulation were calculated based on the counts in the regions of interest on the hearts and livers. In 54 patients with chronic hepatic disorders such as liver cirrhosis, the blood clearance and liver accumulation of 99mTc-GSA were retarded according to the progress of the hepatic disorders. The findings of 99mTc-GSA scintigraphy also reflected the hepatic functions of the patients with large hepatic tumors, obstructive jaundice and acute hepatitis. These results suggest that 99mTc-GSA has the clinical potentials to evaluate the liver functions in the patients with hepatic disorders.

Alcohol can induce a wide spectrum of histological changes in the liver. Three morphologic patterns of alcoholic liver injury are now generally accepted, i.e. fatty change, alcoholic hepatitis and alcoholic cirrhosis, but a broad array of lesions has been added to this list in recent years. These damage patterns differ considerably in their significance as to indication and diagnostic power of liver biopsies. Liver biopsy is recommended in patients with clinically suspected alcoholic liver disease for diagnostic and prognostic reasons. Moreover, clinicians want to exclude nonalcoholic liver diseases that might otherwise be missed. Alcoholic hepatitis, which is associated with increased morbidity and mortality, has the highest degree of diagnostic specificity in biopsies, because its features are well-defined and are mimicked by a rather small group of other causes. When associated with perivenular and pericellular fibrosis, it may provide prognostic parameters. In contrast, fatty liver, which may be induced by alcohol as well as other etiologies, usually does not need liver biopsy, with some exceptions. It may lead to cholestasis severe enough to mimic obstructive jaundice, or may result in abnormal imaging studies suggesting metastases. Verification of histological findings may be important when these circumstances arise. Cirrhosis is easily verified in biopsies of appropriate quality; however, advanced cirrhosis is a morphologically nonspecific alteration, because cirrhotic tissue patterns converge irrespective of their cause. Liver biopsy may help to identify nonalcoholic liver disease in patients suspected of harboring alcoholic liver disease. In fact, up to 20% of biopsies may show other, potentially treatable disorders, thus extending the indication for liver biopsy in situations of complex clinical and laboratory patterns.

One hundred and sixty-eight laparoscopies, performed for various indications between 1985 and 1989, were studied retrospectively and the findings and experiences are reported. The most frequent diagnoses were hepatocellular carcinoma (20%) and liver cirrhosis (18%). Correlation of macroscopic and histopathological diagnosis was satisfactory in hepatocellular carcinoma (74%) and poor in liver cirrhosis (38%). Laparoscopy was judged diagnostic in 45%, diagnostically helpful in 20% and non-contributory in 35% of all cases. The highest yield was obtained in hepatocellular carcinoma and liver cirrhosis, the poorest results in obstructive jaundice. It is concluded that for optimum diagnostic outcome the indication for laparoscopy should be strict and that it should be practised only in those centres where experienced clinicians and competent histopathologists are available.

The serum activity of alcohol dehydrogenase was determined in healthy controls and in patients with liver diseases. The mean activity in hepatoma (6.4 +/- 1.0U/L) was significantly higher (P less than 0.05) than the mean values in liver cirrhosis (2.7 +/- 0.5U/L); hepatitis (4.3 +/- 1.0U/L), obstructive jaundice (2.9 +/- 0.5U/L) and healthy controls (0.7 +/- 0.1U/L). Alcohol dehydrogenase purified by CM-cellulose chromatography from the sera of patients with hepatoma had a higher affinity for butanol long chain saturated and unsaturated alcohols than the purified enzyme from healthy controls. Similarly, hepatoma alcohol dehydrogenase oxidized ethanol very poorly (KM = 154 microM) when compared with that from healthy controls (KM = 40.2 microM). Hepatoma alcohol dehydrogenase was inhibited by pyrazole while those of other liver diseases and the healthy controls were not. These properties of serum alcohol dehydrogenase may prove useful in the early diagnosis of hepatoma since biochemical changes occur before morphological changes in the development of cancer.

Serum Mn-superoxide dismutase (Mn-SOD) was determined in patients with various liver diseases including 31 patients with primary biliary cirrhosis (PBC), 46 with hepatocellular carcinoma (HCC), 17 with liver cirrhosis (LC), 23 with chronic hepatitis (CH) and 12 patients with obstructive jaundice with an enzyme-linked immunosorbent assay using a specific monoclonal antibody. The serum level in patients with PBC (407 +/- 35 ng/ml, mean +/- SEM; n = 31) was significantly increased (p less than 0.01) compared with those of other liver diseases. Mn-SOD level did not correlate with total bilirubin level, gamma-glutamyl transpeptidase activity, alkaline phosphatase activity, alanine aminotransferase activity, IgM, or with ceruloplasmin level in the sera of the patients. When the patients with PBC were histologically subdivided into four groups according to Scheuer's classification (Scheuer PJ. Primary biliary cirrhosis. In: Scheuer PJ, ed. Liver biopsy interpretation. 3rd ed. London: Bailliere Tindall, 1980:47-56), a high level of serum Mn-SOD was noticed in the early stage as well as in the advanced stage of the disease. Immunoblot analysis confirmed the reactivity and specificity of the monoclonal antibody to the enzyme protein in the patients' sera. Immunostaining of a liver biopsy specimen from the patients with PBC revealed increased expression of the enzyme protein in damaged epithelial cells of interlobular bile ducts, bile ductules, and degenerated hepatocytes. These data suggested that free radicals including superoxide anion are possibly involved in the pathogenesis of the disease and Mn-SOD may play some role in a protection against the superoxide anion.

Des-gamma-carboxy prothrombin (DCP), a protein induced by vitamin K absence or antagonist-II (PIVKA-II) was measured in the plasma of patients with primary hepatocellular carcinoma and those with various other hepatobiliary and pancreatic diseases. DCP levels were determined by enzyme immunoassay (E-1023), using an anti-DCP monoclonal antibody. Forty-two of the 91 patients (46.2%) with hepatocellular carcinoma had abnormally elevated levels of DCP, whereas only one of the 24 patients with hepatic cirrhosis showed a slight increase. An increase was also observed in some patients with obstructive jaundice. There was no correlation between plasma levels of DCP and those of serum alpha-fetoprotein (AFP). In most patients with hepatocellular carcinoma, plasma DCP levels normalized after curative surgical resection. Plasma DCP levels were not related to the plasma concentration of vitamin K in the patients with hepatocellular carcinoma. Plasma DCP determination may be useful in the diagnosis and postoperative monitoring of the response of hepatocellular carcinoma.

The amino acid composition of proteins from liver mitochondrial membranes has been studied in patients with normal liver, with biliary diseases and fatty liver, with obstructive jaundice or liver cirrhosis. A characteristic pattern of the amino acid composition in patients with normal liver has been found. In the mitochondrial membranes of patients with fatty liver tryptophan and lysine were decreased while [aspartic acid plus asparagine] and [glutamic acid plus glutamine] were increased compared to their counterpart in the normal liver. In patients with obstructive jaundice of short duration (less than two months) only a slight decrease in methionine content was found, while in the case of liver cirrhosis amino acid composition was markedly changed.

Obstructive jaundice has been known to cause severe hemodynamic disturbance. The present study was therefore designed to assess the cardiac involvement in jaundiced patients. The multiple-gated blood pool cardioscintigraphic studies were done in 9 jaundiced patients who had either cholestatic or obstructive jaundice (mean total bilirubin 29.30 +/- 3.30 mg/dL), and in 8 normal volunteers (total bilirubin less than 1 mg%). None of the patients had evidences of obvious cirrhosis, intrinisic heart disease, or septicemia. Following intravenous dobutamine there was comparable change of blood pressure and heart rate in both groups. However the response of left ventricular ejection fraction (LVEF) to dobutamine (10 micrograms/kg/min x 5 min) was strikingly blunted in the jaundiced patients as compared to that seen in the normal controls (3.56 +/- 0.9 vs. 12.7 +/- 2.2%, p less than 0.005). Our present data thus show that there is blunted myocardial contractile response to the inotropic stimulation in jaundiced patients. Such myocardial refractoriness to beta-1 stimulation may contribute to the susceptibility of jaundiced patients to postoperative shock and acute renal failure.

Hepatic protein synthesis rate (HPS) in human livers were measured to evaluate hepatic functional reserve. HPS of 34 patients who underwent operations were studied and were divided into 4 groups. Normal liver (n = 7), obstructive jaundice (n = 9), liver cirrhosis (n = 8) and other hepatic dysfunction (n = 10). HPS in normal liver was 6.9 +/- 3.0 nmol/mg wet wt./10 min. HPS in obstructive jaundice liver was 17.1 +/- 10.3, and HPS in liver cirrhosis was 47.5 +/- 17.8. There were significant differences among these three groups. HPS correlated well with cholinesterase (r = -0.6533, P less than 0.01) and ICGR15 (r = 0.7315, P less than 0.01). In 15 patients who received hepatectomy, relations between HPS and postoperative complication were studied. There were no complications in patients whose HPS were less than 20 nmol/mg wet wt./10 min. in major hepatic resection and in patient whose HPS were less than 40 in a segmentectomy. Even if HPS were elevated, the operations were safe in subsegmentectomy and partial hepatectomy. So HPS would be one of the good indices to evaluate hepatic functional reserve.
