Abstract
BACKGROUND & AIMS Appropriate management of primary gastric lymphoma is controversial. This prospective, multicenter study aimed to evaluate the accuracy of endoscopic biopsy diagnosis and clinical staging procedures and assess a treatment strategy based on Helicobacter pylori status and tumor stage and grade. METHODS Of 266 patients with primary gastric B-cell lymphoma, 236 with stages EI (n = 151) or EII (n = 85) were included in an intention-to-treat analysis. Patients with H. pylori-positive stage EI low-grade lymphoma underwent eradication therapy. Nonresponders and patients with stage EII low-grade lymphoma underwent gastric surgery. Depending on the residual tumor status and predefined risk factors, patients received either radiotherapy or no further treatment. Patients with high-grade lymphoma underwent surgery and chemotherapy at stages EI/EII, complemented by radiation in case of incomplete resection. RESULTS Endoscopic-bioptic typing and grading and clinical staging were accurate to 73% and 70%, respectively, based on the histopathology of resected specimens. The overall 2-year survival rates for low-grade lymphoma did not differ in the risk-adjusted treatment groups, ranging from 89% to 96%. In high-grade lymphoma, patients with complete resection or microscopic tumor residuals had significantly better survival rates (88% for EI and 83% for EII) than those with macroscopic tumor residues (53%; P < 0.001). CONCLUSIONS There is a considerable need for improvement in clinical diagnostic and staging procedures, especially with a view toward nonsurgical treatment. With the exception of eradication therapy in H. pylori-positive low-grade lymphoma of stage EI and the subgroup of locally advanced high-grade lymphoma, resection remains the treatment of choice. However, because there is an increasing trend toward stomach-conserving therapy, a randomized trial comparing cure of disease and quality of life with surgical and conservative treatment is needed.

Abstract
The importance of sexual transmission in the epidemiology of hepatitis C virus (HCV) infection is still controversial. To assess the risk of heterosexual HCV transmission, we examined eighty patients with chronic HCV-associated liver disease and their spouses in a cross-sectional clinical and serological cohort study. Serum samples from index patients and their spouses were assayed for HCV antibodies and HCV RNA. In the couples positive for both, further HCV genotyping was done. A questionnaire addressing points such as additional risk factors for HCV infection, sexual behaviour or duration of partnership was completed by all couples. HCV antibodies were detected in four (5%) spouses, of whom three (4%) were also positive for HCV-RNA. HCV genotyping revealed concordance (genotype 1) in two couples, indicating a risk of interspousal HCV transmission of 2.5%. Spouses of patients with HCV viraemia and chronic liver disease have a low risk for acquiring HCV. Even long-term spouses seem not to be at increased risk. We therefore suggest that the risk of HCV transmission between monogamous sex partners does not depend on the duration of sexual exposure.

Abstract
AIM To compare the efficacy and tolerability of olsalazine sodium with enteric-coated mesalazine in inducing endoscopic remission in patients with mild to moderate active ulcerative colitis. PATIENTS AND METHODS Patients with mild to moderate active ulcerative colitis were randomized to receive either olsalazine sodium, 3 g/day (n = 88), or mesalazine, 3 g/day (n = 80), for up to 12 weeks. RESULTS Of the patients treated with olsalazine sodium, 52.2% achieved endoscopic remission, compared with 48.8% of patients treated with mesalazine. This difference was not significant (P = 0.67). There was a nonsignificant trend for patients with left-sided colitis or a more severe endoscopic grade to achieve remission if they were treated with olsalazine sodium than if they were treated with mesalazine. Both treatments were comparable with respect to clinical activity index and an investigator's global assessment. Seventy patients reported one or more adverse events; adverse events were seen in 45% of olsalazine sodium-treated patients and in 36% of mesalazine-treated patients. Eleven patients treated with olsalazine sodium and nine patients treated with mesalazine withdrew from the study because of adverse events. One patient treated with olsalazine sodium compared with two treated with mesalazine stopped treatment because of diarrhoea. Serious adverse events occurred in three patients treated with olsalazine sodium and in four treated with mesalazine. CONCLUSION Therapeutic effectiveness and tolerance to the treatment did not differ between olsalazine sodium, 3 g/day, and mesalazine, 3 g/day, in inducing endoscopic remission in patients with mild to moderate active ulcerative colitis within 12 weeks of treatment.

Abstract
Diagnostic procedures in inflammatory bowel diseases (IBD) serve to secure the diagnosis and to optimize treatment. Upon initial diagnosis endoscopy up to the terminal ileum is mandatory including multiple step biopsies. When diagnostic guidelines are followed and adequate clinical information is available, IBD will be correctly classified in about 80 to 90% of cases upon first examination. In contrast endoscopic studies are only of limited value in monitoring treatment. The decision if and when to perform endoscopy during exacerbation of disease must be an individual one. When disease activity is evaluated, a distinction must be made between degree of activity as reflected by laboratory parameters and severity of illness as reflected by the clinical presentation with abdominal complaints, fistulas, abscesses, etc. Distinct activity indices are useful in clinical studies to obtain an objective evaluation of activity and severity of disease. At clinical routine visits questions should not only concern the basic illness but also ask for quality of life and psychosocial status. Only a small number of laboratory tests are needed for basic diagnosis and follow-up. A small bowel enteroclysis should always be performed upon primary diagnosis of Crohn's disease and during the course of disease when there is suspicion of small-bowel involvement. Double contrast barium enema should be limited to special indications as incomplete colonoscopy e.g. due to stenosis or suspected fistula. Sonography is the primary investigation when complications are suspected. CT is useful as an adjunct or when the afore mentioned methods do not show clear findings. NMR is the procedure of choice for detection of pararectal fistulas and abscesses. Transrectal endosonography is comparably good but limited to the experience of the investigators and by patient's tolerability.

Abstract
To identify the risk of pet ownership (i.e., cats and dogs) for alveolar echinococcosis caused by Echinococcus multilocularis, the habits and activities of 21 patients (histologic confirmation or positive serology with corresponding evidence on an ultrasonogram, radiograph, or computed tomography scan) in Austria during the period 1967-1997 were compared with the habits and activities of 84 controls matched by sex, age, and residence. Cat ownership (odds ratio (OR) = 6.47, 95% confidence interval (CI) 1.54-27.29) and hunting (OR = 7.83, 95% CI 1.16-52.77) were independent risk factors associated with alveolar hydatid disease. The study is not in agreement with the hypothesis that eating mushrooms or certain wild berries which grow near the ground are the main risk factors for acquiring this disease. No other behavior patterns or activities studied were identified as risk factors.

Abstract
BACKGROUND Aminosalicylates are used as standard treatment for maintaining remission in ulcerative colitis. As yet, there is no other existing alternative with proven efficacy. In light of the hypothesis that the intestinal environment may contribute to the pathophysiology of ulcerative colitis, a trial was conducted to test the effects of probiotic treatment with an oral preparation of non-pathogenic E. coli. METHODS A total of 120 patients with inactive ulcerative colitis were included in a double-blind, double-dummy study comparing mesalazine 500 mg t.d.s. to an oral preparation of viable E. coli strain Nissle (Serotype 06: K5: H1) for 12 weeks with regard to their efficacy in preventing a relapse of the disease. Study objectives were to assess the equivalence of the clinical activity index (CAI) under the two treatment modalities and to compare relapse rates, relapse-free times and global assessment. RESULTS The start and end scores of the CAI demonstrated no significant difference (P = 0.12) between the two treatment groups. Relapse rates were 11.3% under mesalazine and 16.0% under E. coli Nissle 1917 (N.S.). Life table analysis showed a relapse-free time of 103 +/- 4 days for mesalazine and 106 +/- 5 days for E. coli Nissle 1917 (N.S.). Global assessment was similar for both groups. Tolerability to the treatment was excellent and did not differ. No serious adverse events were reported. CONCLUSIONS From the results of this preliminary study, probiotic treatment appears to offer another option for maintenance therapy of ulcerative colitis. Additional support is provided for the hypothesis of a pathophysiological role for the intestinal environment in ulcerative colitis.

Abstract
AIM To study the effect of prokinetic treatment with cisapride in patients with constipation-predominant irritable bowel syndrome. PATIENTS AND METHODS Ninety-six patients were randomly assigned to treatment with either cisapride 5 mg three times daily or placebo three times daily for a period of 12 weeks. The dosage could be doubled after 4 weeks. Presence of the target symptoms abdominal pain, constipation and abdominal bloating was an obligatory criterion for inclusion in the study. RESULTS After 12 weeks of treatment, 31%, 56% and 27% of the cisapride treated patients were found to be without the three target symptoms (P < 0.05). The corresponding percentages for the placebo-treated patients were 31%, 58% and 19%, respectively, (P < 0.05). The visual analogue scale (VAS) symptom scores assessed by the patients for global rating of bowel disease, general well-being and frequency of stool passage improved significantly within each treatment group (P < 0.05). Evaluation of efficacy parameters using intention-to-treat analysis showed no statistically significant differences between the groups. Using efficacy analysis, the difficulty of stool passage showed a significantly higher improvement with cisapride (P < or = 0.05). CONCLUSIONS These results indicate that cisapride is not superior to placebo in the treatment of constipation and abdominal discomfort as components of irritable bowel syndrome. It may, however, be of use in improving the difficulty of stool passage.

Abstract
INTRODUCTION The clinical significance of the sonographic finding "periportal hyperechogenicity", which is characterized by hard periportal echoes, is largely undetermined. This phenomenon has been reported in a large number of disorders, as well as in healthy persons. METHODS A prospective study of 1853 patients revealed this finding in 12 cases. These 12 patients were followed up after two to four months. RESULTS Only four cases were seen to still have diffuse periportal accentuation in the follow-up, while five patients showed a partially and three a completely normal liver. The laboratory values of these 12 patients were largely normal at the time of diagnosis and follow-up. Periportal accentuation was not correlated with any hepatological disorders. Examination using two different ultrasound devices revealed no major differences. DISCUSSION Overall, these findings confirm the earlier assumption that this sonographic picture designated as periportal hyperechogenicity or accentuation is not diagnostic of any hepatological disorder, nor is it even a sign of disease, because most patients with this phenomenon can be termed hepatologically "healthy".

Abstract
Approximately 50% of patients with chronic hepatitis C respond to treatment with interferon-alpha. The aim of this randomized controlled trial was to evaluate whether an increase in dose of interferon-alpha augments response rate. One hundred thirty-eight patients with newly diagnosed chronic hepatitis C received a three-month course of 3 MU IFN-alpha2b administered every two days. All patients were anti-HCV and HCV-RNA (PCR) positive. Prior to treatment, a liver biopsy was performed. Complete response was defined by normal serum ALT concentrations and disappearance of HCV-RNA. After three months, 60 nonresponders were randomized (stratified according to histology) either to continue 3 MU interferon-alpha2b every two days for another six months (group A, total dose: 410 MU) or to receive increasing doses of interferon-alpha2b (6 MU every two days for three months, followed by 10 MU every two days for three months) (group B, total dose: 870 MU). Serum ALT concentrations were measured monthly and HCV-RNA at three-month intervals. Liver biopsy was repeated six months after end of treatment. Pretreatment characteristics of the randomized patients were: group A: N = 30; male/female: 20/10; age: 54 +/- 10 years; CPH 9, CAH 8, cirrhosis 13; mean ALT 108 +/- 98 units/liter; group B: N = 30; male/female: 21/9; age: 57 +/- 15 years; CPH 10, CAH 9, cirrhosis 11; mean ALT 90 +/- 40 units/liter. At the end of treatment six patients in group B but none in group A became responders [P = 0.011 (Fisher's exact test), intent-to-treat analysis]. All six responders were noncirrhotics. High-dose interferon was not tolerated by six patients in group B. Noncompliance resulted in five dropouts in group A and one in group B. During the six-month follow-up, four of the six responders relapsed. A patient in group A with increased serum ALT concentration but negative HCV-RNA at the end of treatment became a full responder after six months. Of nonresponders to 3 MU interferon alpha2b every two days for three months, 20% responded to higher interferon doses, but none to continued standard dose. Prolonged treatment with interferon may be necessary to obtain a sustained response. However, treatment with higher-dose interferon was not tolerated in 20% of the patients.

Abstract
OBJECTIVES Blood group antigens traditionally have been associated with a risk of developing peptic ulcer and gastric cancer. Helicobacter pylori is a bacterium associated with chronic active gastritis and ulcer disease, and its attachment to gastric mucosa was recently shown in vitro to be mediated by blood group Lewisb and H antigens. This study was designed to test the clinical relevance of this laboratory observation in patients undergoing endoscopy and gastric biopsy. METHODS Blood group phenotypes and gastric biopsies for H. pylori and histology were determined and correlated in 384 patients undergoing upper endoscopy. Blood from healthy blood donors was tested for the same blood group antigens and used as a control group. RESULTS The distribution of blood groups ABO, Lewis, Rhesus, and MN was similar among the patients undergoing endoscopy and a control group of 2369 healthy blood donors from the same geographic area. There was no correlation between H. pylori infection or the H. pylori-associated diseases, peptic ulcer or chronic active gastritis, with any blood group phenotype, including Lewisb, blood group O, or both. CONCLUSION No in vivo correlation between H. pylori infection or disease and Lewisb or H antigen could be demonstrated. Moreover, patients with H. pylori infection and disease have a distribution of blood group antigens similar to a control population.

Abstract
In previous studies measuring intragastric pH in healthy volunteers it was shown that there was a faster onset of action with ranitidine (CAS 66357-35-5) 300 mg effervescent tablets (Zantac) compared to standard tablets. In a single-centre, randomised, open cross-over study the pH-values obtained over 6 h following the administration of one ranitidine 150 mg effervescent tablet were compared with those after aluminium oxide-magnesium hydroxide (algeldrate, CAS 1330-44-5, Al-Mg-hydroxide) 10 ml and placebo in healthy volunteers. 24 healthy male subjects between 19 and 32 years of age entered the study, 19 subjects were available for all three measurements. After an overnight fast, intragastric pH was monitored for 7 h using a glass electrode and a digital data recorder. The time in % during which the pH was > or = 3.5 and the area under the curve of the obtained pH-curves were compared. There was a highly statistically significant difference between ranitidine effervescent tablets versus Al-Mg-hydroxide and placebo whereas there was no such difference between Al-Mg-hydroxide and placebo. The onset of action of ranitidine effervescent tablets was almost immediate. It is concluded that there was a clear superiority of ranitidine effervescent tablets in healthy volunteers and it is suggested that pH-metry in patients with acidity-related diseases should be investigated for a better understanding of the function of effervescent tablets.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in the world. The profile of risk factors associated with HCC includes not only chronic infection with hepatitis B virus and/or hepatitis C virus with subsequent cirrhosis, but also metabolic and alcoholic chronic liver diseases. While the risk of developing cancer is high in patients with cirrhosis, the aim of most screening programmes is to detect small, potentially resectable tumors. Serum alpha 1-fetoprotein lacks both sensitivity and specificity as a screening test and two-thirds of patients with small HCCs have levels below 200 ng/ml. Hepatic resection or liver transplantation at an early stage of HCC, without extrahepatic metastasis, provide complete cure of the disease.

Abstract
BACKGROUND Immunoregulatory properties of cytokines may mediate disordered inflammatory events in inflammatory bowel diseases (IBDs). On the basis of data obtained in experimental colitis, the hypothesis has been advanced that in IBD the balance between interleukin-1 (IL-1) and the naturally occurring IL-1 receptor antagonist (IL-1ra) might influence disease expression. OBJECTIVE We studied the profiles of IL-1ra and acute phase proteins produced by activated macrophages to determine whether the level of IL-1ra in peripheral blood is a marker of disease activity in IBD and a possible differential diagnostic marker. PATIENTS AND METHODS Levels of IL-1ra, serum neopterin, urinary neopterin, alpha 1-glycoprotein and C-reactive protein (CRP) were measured in 80 patients with ulcerative colitis, Crohn's disease or infectious colitis. RESULTS Levels of IL-1ra were markedly increased in patients with active ulcerative colitis or active Crohn's disease compared with those in patients with infectious colitis. Patients with active Crohn's disease had significantly higher serum IL-1ra levels than patients with active ulcerative colitis. Moreover, a positive correlation was found between levels of C-reactive protein, alpha 1-glycoprotein, and serum neopterin and the level of IL-1ra in active Crohn's disease but not in active ulcerative colitis, strongly suggesting that the pathogenesis of the two conditions differs. CONCLUSION Levels of IL-1ra in the peripheral blood of patients with IBD are of clinical relevance, representing a potent marker of disease activity and a possible differential diagnostic marker.

Abstract
BACKGROUND Alpha-1-antitrypsin deficiency is a common autosomal recessive disorder associated with early development of emphysema, liver cirrhosis, and hepatocellular carcinoma. The aim of the present study was to define prognosis and life expectancy in patients with alpha 1-antitrypsin deficiency with and without chronic liver disease. METHODS After a follow-up of 15 years the estimated life table analysis of mortality of 160 patients with alpha 1-antitrypsin deficiency was retrospectively calculated. The survival time was estimated using the Kaplan-Meier survival curves and was compared with the life expectancy of the age- and sex-matched population of west Austria. RESULTS Fifty-four patients with alpha 1-antitrypsin patients had evidence of chronic liver disease; of these, 78% showed positive viral markers. Of the 106 patients with alpha 1-antitrypsin deficiency without chronic liver disease none had evidence of additional viral infection. Life expectancy in patients with alpha-1 antitrypsin deficiency and chronic liver disease was significantly lower than in patients with alpha 1-antitrypsin deficiency without chronic liver disease (p = 0.001). No difference in life expectancy in alpha 1-antitrypsin deficiency without chronic liver disease was found in comparison with that of the normal population. CONCLUSIONS We suggest that in alpha 1-antitrypsin deficiency-associated chronic liver disease it is the high coinfection rather than the inborn error of metabolism itself that is responsible for a deterioration of life expectancy or for the poor prognosis of the disease.

Abstract
Hepatocellular adenomatosis is characterized by the presence of numerous (arbitrarily > 10) adenomas within an otherwise normal liver without a history of glycogen storage disease or steroid hormone therapy. Although the disease is rare, its importance lies in its tendency to produce symptoms such as abdominal pain and its potential for abdominal hemorrhages. However, the prognosis of hepatocellular adenomatosis remains uncertain. Here we describe the case of a 40-yr-old female with hepatocellular adenomatosis without evidence of serious complications, who was observed over a period of 11 yr.

Abstract
The aim of the present was to define prognosis and life expectancy in patients with chronic liver disease of different etiologies and to relate them to an age- and sex-matched normal population. After a follow-up of 15 years, life expectancy of 620 patients with chronic liver disease was retrospectively calculated and compared with an age- and sex-matched normal population. Among patients with cirrhosis, prognosis was dependent upon Child classification (P = 0.001). Patients with alcoholic cirrhosis and fatty liver disease were younger (P = 0.01) and had a lower life expectancy than patients with other causes of chronic liver disease (P = 0.004). Patients with hepatitis B and hepatitis C cirrhosis showed a comparable prognosis and a significantly lower life expectancy than the age- and sex-matched population. Cryptogenic and autoimmune liver diseases showed a comparable life expectancy but a significantly shorter life expectancy than the normal population. In patients with alpha 1-antitrypsin deficiency-associated cirrhosis, a high viral coinfection rate was found (P = 0.01). For patients with noncirrhotic hemochromatosis, prognosis was poorer than that for the age- and sex-matched population. In patients with asymptomatic primary biliary cirrhosis, chronic persistent hepatitis B, and alpha 1-antitrypsin deficiency without cirrhosis, life expectancy was equal to that of the normal population. Prognosis and life expectancy in chronic liver disease depend on stage, cause, and symptoms of chronic liver disease; age; and possibilities of treatment. In patients with hereditary liver disease, additional viral infection of alcohol abuse lead to a significant deterioration of life expectancy. Patients with alcoholic chronic liver disease have the poorest prognosis.

Abstract
AIM Reports in the literautre differ widely with regard to visualisation of the inferior mesenteric artery (IMA) by B-mode ultrasonography. Hence, our study aimed at obtaining exact data on the feasibility of visualising the inferior mesenteric artery via B-mode ultrasonography in a relatively large patient population. METHOD At the outpatient department of gastroenterology and hepatology 51 males (aged 14 to 75 years) and 53 females (aged 16 to 79 years) were examined consecutively by two experienced investigators via B-mode scan within the overall framework of a routine screening programme, in each case after overnight fasting. Knowledge of normal anatomic conditions and of the possible variations of the IMA is mandatory for correct IMA visualisation. RESULTS We succeeded in visualising the IMA via B-mode scan in 41 of the 51 males (80.39%) and in 40 of the 53 females (75.47%), i.e. in a total of 81 of 104 patients (77.88%) in 2-3 cm length. CONCLUSION The results show that IMA can be visualised by B-mode ultrasonography in a manner comparable to visualisation of the superior mesenteric artery (82). This is an essential finding, since duplex sonography of the IMA yields important information on disease activity in inflammatory bowel disease, and B-mode scanning of the IMA is the prerequisite for duplex scanning.

Abstract
Neopterin is produced by macrophages after stimulation with interferon gamma or lipopolysaccharide. Its production is increased in many infectious, autoimmune, and malignant diseases. The aim of this study was to examine whether, on the basis of neopterin as a marker, liver diseases could be classified according to aetiology and stage of disease. A cohort of 264 patients with chronic liver diseases (viral, metabolic, autoimmune, toxic) and 150 normal controls were studied; 136 of the patients had cirrhosis. Increased serum neopterin concentrations were found in 41% of all patients (controls 6.0 (2.2) nmol/l), with patients in the cirrhotic stage of disease showing higher neopterin values (mean (SD) 15.7 (23.6) nmol/ml) than those in the non-cirrhotic stage (9.9 (5.5)). There were no statistically significant differences in the serum neopterin concentrations that could be considered characteristic for different stages of disease classified according to the Child criteria. Such differences in concentrations of neopterin that were found in patients with liver diseases grouped according to underlying causes were only marginal. Serum neopterin concentrations were found to be significantly lower than in any other disease group only in patients with Wilson's disease. The results suggest that activated macrophages participate in the development of chronic liver disease. Measurement of serum neopterin does not offer a reliable method for differentiating between various aetiologies of chronic liver diseases and does not help to predict severity of cirrhosis.

Abstract
OBJECTIVE To determine the therapeutic efficacy and safety of three doses of olsalazine compared with the standard dose of sulphasalazine. DESIGN Randomized double-blind multicentre 6-month study comparing three doses of olsalazine (0.5, 1.25 and 2.0 g daily) and sulphasalazine 2.0 g daily for maintaining remission in patients with ulcerative colitis. SETTING Public hospitals and private practices in Germany, Austria and Switzerland. PATIENTS A total of 162 patients with ulcerative colitis in remission. RESULTS According to intention-to-treat analysis, the failure rates of the different treatment groups were not significantly different (36, 49 and 24% for 0.5, 1.25 and 2.0 g olsalazine daily and 32% for 2.0 g sulphasalazine daily). Olsalazine and sulphasalazine showed a tendency towards lower failure rates in extended (28%) than in distal disease (44%). The withdrawal rate due to adverse effects was 4%, the most frequent single event being diarrhoea (2.5, 5.2 and 11.7% for 0.5, 1.25 and 2.0 g olsalazine daily and 0% for sulphasalazine daily). CONCLUSION This study found no significant differences between the therapeutic efficacy or safety of 0.5-2.0 g olsalazine daily. Because of its sulpha-free formulation olsalazine may, however, be preferred to sulphasalazine.

Abstract
Wilson's disease is a lethal defect in copper metabolism causing a continual increase in tissue copper concentrations that become toxic to the liver, brain, kidney, eye, skeletal system, and several other tissues and organs. The liver is unique among these in being both the site of the etiologic biochemical abnormality and the organ that is always affected by copper toxicosis. Although myocardial muscle involvement has been reported in association with Wilson's disease, copper deposits in peripheral muscle tissue have not yet been described. A case of a young patient with Wilson's disease who developed recurrent episodes of acute rhabdomyolysis is presented, and the accumulation of copper in muscle tissue as a possible complication is discussed.

Abstract
The aim of the present study was to determine the prevalence of hepatocellular carcinoma in adults with heterozygous alpha 1-antitrypsin deficiency and to assess the presence of possible co-risk factors for the development of hepatocellular carcinoma. Two hundred and forty patients with cirrhosis of different aetiologies and 130 patients with alpha 1-antitrypsin deficiency without evidence of chronic liver disease were investigated. Out of the 240 patients with cirrhosis, 61 patients (25%) were found to have alpha 1-antitrypsin deficiency, 36 patients (15%) had chronic hepatitis C infection, 50 (21%) had chronic hepatitis B and 24 (10%) had hepatitis C and hepatitis B infection. Thirty patients (12%) had cryptogenic cirrhosis and 39 (16%) alcoholic cirrhosis. The prevalence of hepatocellular carcinoma in patients with alpha 1-antitrypsin deficiency-associated cirrhosis was comparable to that of hepatocellular carcinoma in patients with cirrhosis of other aetiologies. Positive viral markers were found in 67% of the patients with alpha 1-antitrypsin deficiency-associated cirrhosis with hepatocellular carcinoma. In contrast, in the group of 130 patients with alpha 1-antitrypsin deficiency but without clinical and laboratory signs of chronic liver disease, none was found to have hepatocellular carcinoma (p = 0.001). Our results indicate that heterozygous alpha 1-antitrypsin deficiency-associated cirrhosis is a risk factor for hepatocellular carcinoma, but this is due to chronic liver disease and not due to the metabolic disorder itself.

Abstract
Increased activation of lymphocytes in inflammatory bowel disease is reflected by alterations of various immunological functions including enhanced spontaneous secretion of rheumatoid factor by mononuclear cells. since in rheumatic diseases increased secretion of rheumatoid factor is associated with decreased levels of beta-endorphin in circulating blood mononuclear leukocytes, we investigated levels of leukocyte beta-endorphin in inflammatory bowel disease and compared them with those in hepatobiliary disorders and in healthy subjects. Levels of beta-endorphin were measured in extracts from peripheral blood mononuclear leukocytes by radioimmunoassay. beta-Endorphin levels ranged from 0 to 67 pg/10(6) cells. Mononuclear leukocytes from ulcerative colitis patients contained as much beta-endorphin as those from healthy control subjects. In patients with Crohn's disease, levels of beta-endorphin were reduced by as much as roughly 50%. An inverse relationship was found between leukocyte beta-endorphin on the one hand and erythrocyte sedimentation rate, blood granulocyte or thrombocyte counts, and C-reactive protein levels in plasma on the other. In patients with various hepatobiliary disorders including fatty liver disease, viral hepatitis, primary biliary cirrhosis, and cryptogenic or alcoholic cirrhosis, beta-endorphin levels were not significantly different from the normal range values. Data indicate that leukocyte beta-endorphin may be involved in regulation of the systemic inflammatory activity of Crohn's disease.

Abstract
The importance of hepatitis C virus (HCV) infection as a cause of chronic liver disease has become clear with the introduction of serologic detection methods. On the basis of epidemiologic evidence the parenteral way of infection has been considered to be the most important one. However, the epidemiologic data regarding the significant route of infection are still limited. To study the ways of HCV-infection and their possible influence on the course of the disease, 73 patients with chronic hepatitis C infection were examined. Setting was the out-patient department of Gastroenterology of our University Hospital. Patients history, completed by a questionnaire, laboratory findings and liver histology were analysed. The study indicated that in 50% of the patients transmission had occurred through parenteral infection, the other 50% had been infected through the non-parenteral (sporadic) way. The study revealed further that the way of infection has an influence on the progression of liver disease with the patients infected sporadically showing histologically more serious hepatic changes. In 50 patients HCV-infection was the only cause of their chronic liver disease, in 23 patients additional pathogenic factors were detected. These 23 patients showed a rapid progress of the disease. Therefore, HCV-infection cannot be considered any longer as a disease that is primarily transmitted parenterally. Due to the large number of sporadic infections, HCV-infection will continue to be of great epidemiologic importance even after the effective elimination of contaminated blood products.

Abstract
BACKGROUND Pantoprazole is a new substituted benzimidazole that blocks the H+/K(+)-ATPase in the gastric mucosa and thus inhibits acid secretion. METHODS Efficacy and tolerability of pantoprazole (40 mg at breakfast) and ranitidine (300 mg at bedtime) in the treatment of uncomplicated acute duodenal ulcer were compared in a double-blind randomized multicentre trial. RESULTS Of 202 outpatients who entered the study, 185 terminated the treatment without violation of the protocol. After 2 weeks of treatment, healing rates (protocol correct) with pantoprazole and ranitidine were 81 and 53%, respectively (P < 0.001), the corresponding results after 4 weeks were 97 and 83% (P < 0.01). Pantoprazole was more effective with respect to symptom relief. Both treatments were well tolerated. CONCLUSION Pantoprazole 40 mg at breakfast is superior to ranitidine 300 mg at bedtime in the short-term treatment of acute, uncomplicated duodenal ulcer.

Abstract
We measured concentrations of guanosine 3',5'-monophosphate (cGMP) in plasma and urine of healthy subjects and patients with congestive heart failure, renal impairment, neoplastic disease, and hepatic cirrhosis. There was no correlation between cGMP concentrations in urine and in plasma. In all patients except those with renal impairment, urinary cGMP concentrations were significantly higher than in healthy persons. Only patients with heart failure or renal impairment showed significantly increased plasma cGMP concentrations. In contrast, cGMP in urine does not relate to the clinically assessed severity of heart failure (New York Heart Association functional classes). Determination of cGMP in plasma results in higher sensitivity and specificity for diagnosing heart failure than measurement of cGMP in urine.

Abstract
The diagnosis of gastric lymphoma in endoscopic biopsy specimens remains difficult despite the emergence of accepted criteria for the histologic diagnosis of lymphomas originating from mucosa-associated lymphoid tissue (MALT). The sensitivity and validity of immunoglobulin (Ig) gene rearrangement analysis of mucosal biopsies for the diagnosis of malignant B-cell lymphoma were investigated in comparison with conventional histology and immunohistology. Biopsy specimens from 34 different endoscopies of 20 patients with a previous history, or tentative diagnosis of gastric lymphoma, and 12 control samples were analyzed for the presence of clonal Ig gene rearrangements. A clonal B-cell population was detected by Southern blot analysis in all patients with a definitive histologic diagnosis of lymphoma. In addition, in two patients the detection of clonal rearrangements in biopsy specimens preceded by several months the histologic diagnosis of lymphoma, and clonality was confirmed in three further patients where histology remained inconclusive. In some cases of low-grade MALT-lymphoma, discrete spreading of malignant cells within chronically inflamed mucosa was suggested by the presence of identical clonal rearrangements in all simultaneously obtained biopsies, with or without histologically detectable involvement by lymphoma. Our results show that immunoglobulin gene rearrangement studies of endoscopic biopsy samples are an additional powerful tool for the diagnosis of gastric lymphoma, especially for detecting early recurrence, and improve the preoperative assessment of the extent of mucosal involvement.

Abstract
We investigated 37 patients with ascites and liver cirrhosis in order to examine whether on the basis of correlation of cytokines and acute phase proteins of the ascitic fluid, prognosis of spontaneous bacterial peritonitis can be made. Significantly enhanced levels of interleukin-6, as well as acute phase reactants alpha-1-antitrypsin and C-reactive protein were found in the ascitic fluid of patients with spontaneous bacterial peritonitis. The levels of tumour necrosis factor alpha (TNF-alpha), neopterin, interleukin 2-receptor and granulocyte-macrophage colony stimulating factor were higher in patients with spontaneous bacterial peritonitis, but without statistical significance, whereas no differences were found between the interferon gamma, interleukin-2 and interleukin-1 levels. In addition, interleukin-6, TNF-alpha and neopterin levels were found to correlate significantly with the outcome of the disease. These findings show that acute phase reaction occurs in the ascitic compartment in correlation with the development of spontaneous bacterial peritonitis.

Abstract
The proinflammatory cytokines interleukin-1 and tumor necrosis factor-alpha are thought to play important roles in the pathophysiology of liver disease. Specific antagonists of these cytokines have been found in recent years. Interleukin-1 receptor antagonist is a specific interleukin-1 antagonist. The soluble receptor derived from the cell-surface p55 tumor necrosis factor receptor p55 is a naturally occurring substance that inhibits the biological effects of tumor necrosis factor. We used specific radioimmunoassays to detect circulating interleukin-1 receptor antagonist and tumor necrosis factor soluble receptor p55 levels in 14 patients with acute viral hepatitis and in 160 patients with various chronic liver diseases. Levels of interleukin-1 receptor antagonist and, especially, tumor necrosis factor soluble receptor were markedly increased in most patients with chronic liver disease regardless of pathogenesis and in viral hepatitis. Patients with chronic liver disease and cirrhosis showed significantly higher levels of both cytokine antagonists than did noncirrhotic patients. Correlations between interleukin-1 receptor antagonist and tumor necrosis factor soluble receptor were more significant than those of either antagonist with C-reactive protein or blood sedimentation rate. Interleukin-1 receptor antagonist and tumor necrosis factor soluble receptor levels were also positively correlated with bilirubin and AST levels. We conclude that circulating levels of interleukin-1 receptor antagonist and tumor necrosis factor soluble receptor may reflect ongoing disease activity and probably modulate some effects of endogenous interleukin-1 and tumor necrosis factor.

Abstract
Impaired blood clotting precludes percutaneous liver biopsy for histologic examination of liver tissue. The transjugular or laparoscopic approach are ways to reduce the risk of bleeding. These techniques, however, are laborious and confined to specialized centers. Methods of plugging the needle track with sealant presented so far are hampered by the need to leave either the cannula in situ or the need for a second percutaneous approach for the application of the sealant. We have tested a combined plugging-biopsy device allowing to perform the biopsy as a one-step procedure in patients with impaired clotting under laparoscopic vision control. In 37 patients either a modified Trucut or Menghini needle was tested. Handling of the Trucut needle proved easier. Tissue yield was satisfactory with both needles. Only one episode of bleeding was observed with a prototype Menghini needle. We conclude, that the combined plugging-biopsy device is a safe and reliable tool for obtaining liver tissue in patients with impaired blood coagulation.

Abstract
Ten patients with chronic hepatitis B received increasing doses of nIL-2 (30,000 U, 100,000 U, 300,000 U, 1.0 million U) subcutaneously in a phase I trial. Each dose was applied once per week over 3 weeks. Serum samples were taken before and 2, 12, 24, 48 and 72 h after the first application of each dose level. Serum concentrations of interleukin-1 (IL-1), IL-2, IL-6, interferon-alfa (IFN-alpha), IFN-gamma, tumor necrosis factor-alpha (TNF-alpha) and GM-CSF as well as the cytokine-dependent serum components neopterin, beta-2-microglobulin (B2M), C-reactive protein (CPR), soluble IL-2-receptor (sIL-2R) and 2'-5'-oligoadenylate synthetase (2-5 OA) were assayed using ELISAs and RIAs. None of the samples tested contained measurable cytokine levels other than IL-2. A low and non-toxic dose of 300,000 U nIL-2 was already biologically active with induction of neopterin, B2M and sIL-2R. Dose-dependent changes peaked 24-48 h after application. The same patients were then enrolled in a phase II trial. Treatment in five of the patients was continued twice per week for 3 months with a biologically active dose of 300,000 U nIL-2 subcutaneously. Two of these patients as well as another five patients from the original group were treated with 1.0 million U nIL-2 subcutaneously, twice weekly for 3 months. Neither a biologically active but non-toxic dose of 300,000 U nIL-2, nor a toxic dose of 1.0 million U resulted in permanent clearance of hepatitis B early antigen (HBeAg).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Neopterin, a product of human monocytes/macrophages stimulated by gamma-interferon, was previously found to be correlated with clinical activity of Crohn's disease. The present investigation attempted to identify more precisely the role of neopterin for assessment of clinical activity in a multivariate setting. A broad panel of clinical and laboratory variables was obtained on 76 patients. Neopterin was determined in urine by high performance liquid chromatography. Using a 4-point clinical activity score as dependent variable, multivariate linear discriminant analyses were performed in order to identify subsets of statistically independent laboratory activity indices. Neopterin was shown to be an independent indicator for clinical activity. The significant variables were then tested together with the eight constituent variables of the Crohn's Disease Activity Index. The resulting model, which consisted of the three laboratory variables--erythrocyte sedimentation rate, serum protein and neopterin, together with pain score--was further subjected to two multivariate techniques for comparison: polychotomous logistic regression analysis and the technique of classification and regression trees. By all methods, neopterin was included into the multivariate models, confirming that its determination aids in the assessment of clinical activity in Crohn's disease.

Abstract
OBJECTIVE To determine the prevalence of chronic liver disease in adults with homozygous (Pi ZZ) and heterozygous (Pi Z) alpha 1-antitrypsin deficiency and to assess the presence of other possible risk factors for the development of chronic active hepatitis and cirrhosis of the liver in these patients. DESIGN Cross-sectional study. SETTING A referral-based university hospital. PATIENTS Consecutive patients (164) with the Pi ZZ and Pi Z phenotype with and without chronic liver disease. MEASUREMENTS The presence of antibody to hepatitis C virus (anti-HCV) was determined using an assay incorporating synthetic peptide antigen from capsid protein (United Biomedical [UBI] assay) and a second-generation enzyme immunoassay (Abbott test); the presence of antibody to hepatitis B virus (anti-HBV) was determined using radioimmunoassays incorporating hepatitis B surface antigen (HBsAg) and hepatitis B core antigen (HBcAg); assays for antinuclear antibody and antimitochondrial antibody (M2 subtype) were also done, and alcohol abuse was assessed by history. RESULTS Among patients with cirrhosis (32%), 62% were anti-HCV positive by the Abbott test (P = 0.006), and 41% were anti-HCV positive by the UBI assay (P = 0.007). Thirty-three percent of patients with cirrhosis had hepatitis B virus (HBV) infection (P = 0.01); 41% had a history of alcoholism; and 12% had features of autoimmune liver disease. Only five patients (9%) with cirrhosis had no other risk factor for chronic liver disease. Among patients with chronic active hepatitis (7%), 80% were anti-HCV positive by the Abbott test (P = 0.002), and 75% were anti-HCV positive by the UBI assay (P less than 0.001). Thirty percent of patients with chronic active hepatitis had HBV infection (P = 0.023); 18% had autoimmune hepatitis; and 8% abused alcohol. Only two patients (17%) had no additional risk factor for the development of chronic active hepatitis. Among patients with steatosis of the liver (48%), 5% were anti-HCV positive by the Abbott test, and none were anti-HCV positive by the UBI assay; 18% had serologic evidence of past HBV infection, and 28% abused alcohol. Among patients without chronic liver disease (13%), no viral infection could be found; 9% were alcoholics. CONCLUSIONS Chronic liver disease in patients with alpha 1-antitrypsin deficiency is associated with a high prevalence of viral infection; this infection, rather than alpha 1-antitrypsin deficiency alone, may be the cause of the liver disease in such patients.

Abstract
Serum levels of interleukin-1 (IL-1 beta), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-alpha), interferon gamma (IFN-gamma), and C-reactive protein (CRP) were investigated in patients with chronic liver diseases (CLD) and correlated with the type of underlying disease and various clinical and laboratory parameters. Two hundred sixty-four patients suffering from various CLD were studied; 136 cases presented with liver cirrhosis, and 128 patients were in the noncirrhotic stage of their underlying liver diseases. Serum levels of IL-1 beta, IL-6, TNF-alpha, IFN-gamma, and CRP were elevated in patients with CLD. Endogenous cytokine patterns in CLD were stage dependent and only marginally affected by the type of underlying disease. The cirrhotic group of CLD patients showed higher serum levels in IL-1 beta, IL-6, TNF-alpha, and CRP than did noncirrhotic cases, and these differences reached the level of statistical significance. IL-1 beta and TNF-alpha values were closely correlated but did not correlate with IL-6 levels. Elevated concentrations of cytokines represent a characteristic feature of CLD regardless of underlying disease. This and the apparent stage-dependency suggest that enhanced endogenous cytokine levels represent a consequence of liver dysfunction rather than of inflammatory disease.

Abstract
Consensus analysis has been proposed as a statistical method by which the efficacy of clinical and laboratory tests of inflammatory activity can be assessed. This technique is claimed to overcome the need for an external "gold standard" as a reference method; instead, the consensus of all tests is used as the gold standard. We have evaluated the reliability of consensus analysis using data collected from patients with Crohn's disease. Our results demonstrate that the technique depends strongly on the correlation structure underlying the set of measures of disease used for analysis. This observation was supported by a series of conventional cluster analyses of the same set of variables. Furthermore, slight modifications of the algorithm had profound effects on the final result. We conclude that for the evaluation of tests of inflammatory activity, an external reference method, albeit an imperfect one, remains indispensable.
