Abstract
BACKGROUND Helicobacter pylori plays a decisive role in the pathogenesis of gastric marginal zone B cell lymphoma of mucosa associated lymphoid tissue (MALT), and eradication therapy has become a widely accepted initial treatment of stage I disease. OBJECTIVE To determine the long term outcome of patients undergoing exclusive H pylori eradication therapy. DESIGN A prospective series of patients with newly diagnosed marginal zone B cell lymphoma of MALT. SETTING Multicentre study in Germany and Austria. PATIENTS Ninety five patients; 90 of these (five lost to follow up) with a mean age of 54.3 (27-85) years were followed up for at least 12 months. INTERVENTION Complete staging work up revealing stage I disease and H pylori infection. Patients received triple therapy (OMC: omeprazole 20 mg twice daily, metronidazole 400 mg twice daily, and clarithromycin 250 mg twice daily; or OAC: omeprazole 20 mg twice daily, amoxycillin 1000 mg twice daily, and clarithromycin 500 twice daily) for one week. RESULTS Median follow up was 44.6 (12-89) months. H pylori was successfully eradicated in 88 patients (98%); in two patients eradication therapy failed. Long term outcome was characterised by complete regression of lymphoma in 56 patients (62%), minimal residual disease in 17 patients (18%), partial remission in 11 patients (12%), no change in four patients (4%), and progressive disease in two patients (2%). Four patients with complete remission relapsed after 6, 8, 8, and 15 months, one revealing reinfection by H pylori. Regression rate was higher in stage I1 disease compared with stage I2, as diagnosed by endoscopic ultrasound. CONCLUSION The majority of patients with low grade gastric MALT lymphoma treated by exclusive H pylori eradication have a favourable long term outcome, offering a real chance of cure.

Abstract
BACKGROUND Endoscopic ultrasound (EUS) is considered the best technique for local staging of primary gastric lymphomas. Its role in the follow up of patients with gastric lymphoma following organ conserving strategies has not been established. AIM To compare endosonographic response assessment with results of histological evaluation. PATIENTS AND METHODS Thirty three patients with primary gastric lymphomas underwent pretreatment EUS and were followed endosonographically every 3-6 months after administration of organ conserving treatment modalities. A wall thickness of <or=4 mm with preserved five layer structure and the absence of suspicious lymph nodes was defined as endosonographic remission. Decrease in wall thickness, increase in echogenicity, and regression of lymph nodes were tested for their value to predict histological remission. RESULTS A total of 158 endosonographies were performed (median 4; range 2-12). Within a median follow up period of 15 months (range 3-48), 27 (82%) patients achieved complete histological remission while endosonographic remission was found in 21 (64%) patients. Eighteen patients achieved both forms of remission, with endosonographic remission occurring later (35.1 (11-212.9) weeks v 17.6 (11-97.9) weeks; median (range); p<0.02) than histological remission. A further three patients demonstrated a false negative remission on EUS. Histological relapse was paralleled by endosonographic relapse in only one of five patients. None of the tested endosonographic parameters was able to predict histological remission. CONCLUSIONS In view of the inferior accuracy of EUS when compared with histology, gastroscopy with biopsy seems sufficient for the routine follow up of patients with gastric lymphoma.

Abstract
BACKGROUND There is much controversy as to whether or not treatment of Helicobacter pylori reduces the occurrence of peptic ulcers during therapy with a non-steroidal anti-inflammatory drug (NSAID). AIM To assess the efficacy of triple therapy or omeprazole on the occurrence of diclofenac associated ulcers in H pylori positive patients. METHODS This was a randomised, double blind, placebo controlled, multicentre trial in H pylori positive patients requiring NSAID therapy who had no past or current peptic ulcer. They received diclofenac 50 mg twice daily for five weeks in combination with one of the four randomly assigned treatments: anti-H pylori treatment for one week (omeprazole 20 mg+clarithromycin 500 mg+amoxicillin 1 g, all twice daily) followed by placebo for four weeks (OAC-P); anti-H pylori treatment for one week followed by antisecretory treatment with omeprazole 20 mg once daily for four weeks (OAC-O); omeprazole 20 mg once daily for five weeks (O-O); or placebo for five weeks (P-P). Patients were endoscoped before and after treatment. RESULTS Data from 660 patients were included in an intention to treat analysis. The occurrence of peptic ulcers in the four treatment groups during the study period was: 1.2% for OAC-P, 1.2% for OAC-O, 0% for O-O, and 5.8% for P-P (p<0.05 between placebo and all active treatment groups). Patients who received active treatment developed therapy requiring dyspeptic symptoms less frequently than those who received placebo (p<0.05 between placebo and all active treatment groups). CONCLUSIONS In H pylori infected patients, all three active therapies reduced the occurrence of NSAID associated peptic ulcer and dyspeptic symptoms requiring therapy.

Abstract
BACKGROUND Recent data suggest that chemotherapy with the cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) regimen is a highly effective treatment for localised primary gastric lymphoma of diffuse large B-cell histology (DLBCL). We have reported that the large majority of patients achieve complete remission (CR) following three cycles of treatment, and now provide an updated series with special emphasis on patients receiving only short-term chemotherapy. PATIENTS AND METHODS All patients with a histologically verified diagnosis of gastric DLBCL in stages EI and EII(1) undergoing chemotherapy with the CHOP regimen were evaluated. Data analysed included clinical stage, histology [presence of an additional mucosa-associated lymphoid tissue (MALT) component], evidence of Helicobacter pylori infection, H. pylori eradication, time to CR, survival and regular restaging (i.e. after three and six cycles, respectively). RESULTS A total of 37 patients with DLBCL of the stomach with localised disease were identified, five of whom also had a MALT component. Twenty-two patients presented with stage EI and 15 with stage EII(1) disease. All patients were given chemotherapy as sole management of their lymphoma; 36 patients received CHOP, while one patient was given CHOP along with rituximab. Thirty-two (86%) achieved a CR after a maximum of three cycles, while only four patients had to be given six cycles for CR. In total, nine of 37 patients (24%) discontinued therapy earlier than scheduled: one patient received one cycle, two received two, six received three and one patient received four cycles. Two of these patients stopped treatment due to toxicity, i.e. protracted thrombocytopenia or chemotherapy extravasation. One additional patient died after one cycle of treatment; autopsy disclosed no signs of remaining lymphoma. Three patients have died after a median follow-up of 39 months (including the one patient who discontinued therapy after one cycle of treatment), while the remaining 34 patients are alive without evidence of disease. Twenty-four out of 37 patients (65%) had also undergone H. pylori eradication (including six of nine patients receiving only short-term treatment). CONCLUSIONS DLBCL of the stomach appears to be a highly chemosensitive disease. Our data question the need for full-term CHOP treatment in patients achieving CR upon first follow-up. However, recent data suggest that additional H. pylori eradication might have contributed to the excellent results achieved in our series.

Abstract
The incidence of celiac disease has increased considerably during the last two decades. Celiac Disease is now diagnosed in adults at least as frequently as in children. A prevalence of about 1:200 seems reasonable in central Europe. Besides the typical symptomatic presentation, silent, latent and potential celiac disease are found. Oligo- to asymptomatic courses (silent celiac disease) are increasingly found in all age groups. Endomysial antibodies and tissue-transglutaminase antibodies are sensitive and specific for about 95% of celiac patients. However, the final diagnosis is only done by a - mostly endoscopical - biopsy from the distal part of the duodenum, demonstrating hyperplastic villous atrophy of the mucosa with increased numbers of intraepithelial lymphocytes. The biopsies should be classified histologically according to the modified Marsh criteria. Increased prevalence in family members (10 to 15%) and in associated diseases (e.g. diabetes mellitus) lead to the recommendation of active screening in populations at risk. Although the clinical symptoms are rather variable and different, the response to a lifelong strict gluten free diet is nearly 100%. So-called refractory celiac disease is very rare. There are numerous associated diseases as dermatitis herpetiformis, diabetes mellitus type I, thyroid and neurologic diseases. The most frequent complications are retardation of growth in childhood, early onset osteoporosis, and an increased risk of abortions. The most severe complication is intestinal lymphoma. Especially patients with late diagnosis and bad dietary adherence are at risk. A regular follow-up of patients, rather with antibody tests than with duodenal biopsies is recommended to test and secure dietary compliance.

Abstract
BACKGROUND AND AIMS Gastric MALT-lymphoma is thought to be related to chronic antigenic stimulation provided by Helicobacter pylori (HP). As clonal expansion of gastric B cells not related to HP has been demonstrated in patients with autoimmune disease (AD), we have analysed whether AD adversely influences response of MALT-lymphoma following HP-eradication. PATIENTS AND METHODS Retrospective analysis of all patients with early stage gastric MALT-lymphoma treated with HP-eradication was performed. The presence of AD was evaluated by personal questioning for specific symptoms and serologically by analysis of rheumatoid factor, antinuclear antibodies and thyroid autoantibodies. RESULTS A total of 22 patients were identified receiving only antibiotic treatment for initial management, and six presented with an autoimmune condition: three had Sjögren's syndrome, one polymyalgia rheumatica, one autoimmune thyroiditis along with psoriasis, and one patient had only autoimmune thyroiditis. Successful eradication of HP was achieved in all patients, and 15 of 22 patients (68%) achieved complete response of the lymphoma, while none out of the six patients with an autoimmune disorder responded to HP-eradication. CONCLUSION Apart from questioning the role of HP in the development of lymphoma in such patients, these results suggest that patients with autoimmune disease might not be optimal candidates for HP-eradication even in case of early stage lymphoma.

Abstract
AIM: To test the hypothesis that Helicobacter pylori eradication alone can reduce the incidence of gastric cancer in a subgroup of individuals with an increased risk for this fatal disease.
METHODS: It is a prospective, randomized, double blind, placebo controlled multinational multicenter trial. Men between 55 and 65 years of age with a gastric cancer phenotype of Helicobacter pylori gastritis are randomized to receive a 7 day course of omeprazole 2 × 20 mg, clarithromycin 2 × 500 mg, and amoxicillin 2 × 1 g for 7 days, or omeprazole 2 × 20 mg plus placebo. Follow-up endoscopy is scheduled 3 months after therapy, and thereafter in one-year intervals. Predefined study endpoints are gastric cancer, precancerous lesions (dysplasia, adenoma), other cancers, and death.
RESULTS: Since March 1998, 1524 target patients have been screened, 279 patients (18.3%) had a corpus dominant type of H. pylori gastritis, and 167 of those were randomized (58.8%). In the active treatment group (n = 86), H. pylori infection infection was cured in 88.9% of patients. Currently, the cumulative follow-up time is 3046 months (253. 38 patient years, median follow up 16 months). So far, none of the patients developed gastric cancer or any precancerous lesion. Three (1.8%) patients reached study endpoints other than gastric cancer.
CONCLUSION: Among men between 55 and 65 years of age, the gastric cancer phenotype of H. pylori gastritis appears to be more common than expected. Further follow up and continuing recruitment are necessary to fulfil the main aim of the study.

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
Helicobacter pylori (H.p.) causes active chronic gastritis in nearly all infected patients. Cytotoxic factors elaborated by H.p. as well as autoimmune cell damage from the abundant inflammatory response contribute to gastric epithelial cell injury. Antrum gastritis increases gastrin release. The impact of H.p.-infection on gastric acid physiology is complex and usually results in increased gastric acid secretion in duodenal ulcer patients and diminished acid output in patients with gastric cancer. Multiple clinical outcomes including asymptomatic gastritis, duodenal ulcer, gastric ulcer, gastric carcinoma and gastric MALT lymphoma are associated with H.p.-infection. Differences in disease manifestation seem to result from a complex interaction of bacterial virulence, host factors as well as environmental factors. The acid-secretory ability of the infected individual seems to be the main variable determining outcome: Patients with high acid production typically develop antrum-predominant gastritis and are at an increased risk for duodenal ulcer. In contrast patients with low gastric acid secretion frequently develop pangastritis, which may progress to chronic atrophic gastritis and carcinoma.

Abstract
Lymphoma of the mucosa-associated lymphoid tissue (MALT) type usually arises in MALT acquired through chronic antigenic stimulation triggered by persistent infection and/or autoimmune processes. Due to specific ligand-receptor interactions between lymphoid cells and high-endothelial venules of MALT, both normal and neoplastic lymphoid cells display a pronounced homing tendency to MALT throughout the body. In the case of neoplastic disease these homing properties may be responsible for lymphoma dissemination among various MALT-sites. According to this concept, we have standardized staging procedures in all patients diagnosed with MALT-type lymphoma. All patients with MALT-type lymphoma underwent standardized staging procedures before treatment. Staging included ophthalmologic examination, otolaryngologic investigation, gastroscopy with multiple biopsies, endosonography of the upper gastrointestinal tract, enteroclysis, colonoscopy, computed tomography of thorax and abdomen and bone marrow biopsy. Biopsy was performed in all lesions suggestive for lymphomatous involvement, and evaluation of all biopsy specimens was performed by a reference pathologist. 35 consecutive patients with histologically verified MALT-type lymphoma were admitted to our department. Twenty-four patients (68%) had primary involvement of the stomach, five (15%) had lymphoma of the ocular adnexa, three (8.5%) had lymphoma of the parotid, and three (8,5%) of the lung. Lymph-node involvement corresponding to stage EII disease was found in 13 patients (37%), only one patient with primary gastric lymphoma had local and supradiaphragmatic lymph-node involvement (stage EIII). Bone marrow biopsies were negative in all patients. Overall, eight of 35 patients (23%) had simultaneous biopsy-proven involvement of two MALT-sites: one patient each had lymphoma of parotid and lacrimal gland, conjunctiva and hypopharynx, conjunctiva and skin, lacrimal gland and lung, stomach and colon, and stomach and lung. The remaining two patients had bilateral parotideal lymphoma. Staging work-up was negative for lymph-node involvement in all of these eight patients. The importance of extensive staging in MALT-type lymphoma is emphasized by the demonstration of multiorgan involvement in almost a quarter of patients. In addition, our data suggest that extra-gastrointestinal MALT-type lymphoma more frequently occurs simultaneously at different anatomic sites than MALT-type lymphoma involving the GI-tract.

Abstract
BACKGROUND Surgical intervention and combined modality treatment including radiation and chemotherapy have been studied widely in patients with high grade gastric B-cell lymphoma, whereas to the authors' knowledge the role of chemotherapy alone in patients with localized disease has not been investigated extensively. METHODS Twenty-five consecutive patients with primary high grade gastric B-cell lymphoma of localized modified Ann Arbor Stages IE and IIE were studied prospectively at the study institution. Patients age < 75 years (n = 17; age range, 41-75 years) were given a standard regimen comprised of doxorubicin, cyclophosphamide, vincristine, and prednisone (CHOP), whereas patients age > 75 years (n = 8; age range, 82-93 years) were treated at a reduced dose. Restaging was performed after 3 and 6 cycles, followed by every 3 months for the first 2 years, and every 6 months thereafter. RESULTS A total of 123 cycles were administered to the study patients, with the median number of 6 cycles per patient (range, 1-9 cycles). At a median follow-up of 24 months (range, 1.5-87+ months), 22 patients were alive without evidence of disease and 3 patients had died (1 patient death was treatment-related). Twenty-four patients who were considered evaluable achieved a complete remission, 21 patients after 3 cycles and the remaining 3 patients after 6 cycles of treatment. Side effects generally were manageable, with only one patient requiring premature discontinuation of treatment due to protracted thrombocytopenia after three courses of therapy, and tolerance was not different between the two age groups. No recurrences were observed at last follow-up. CONCLUSIONS The authors believe that chemotherapy using the CHOP regimen is highly effective in the treatment of patients with localized primary high grade gastric lymphoma.

Abstract
BACKGROUND Surgical intervention and combined modality treatment including radiation and chemotherapy have been studied widely in patients with high grade gastric B-cell lymphoma, whereas to the authors' knowledge the role of chemotherapy alone in patients with localized disease has not been investigated extensively. METHODS Twenty-five consecutive patients with primary high grade gastric B-cell lymphoma of localized modified Ann Arbor Stages IE and IIE were studied prospectively at the study institution. Patients age < 75 years (n = 17; age range, 41-75 years) were given a standard regimen comprised of doxorubicin, cyclophosphamide, vincristine, and prednisone (CHOP), whereas patients age > 75 years (n = 8; age range, 82-93 years) were treated at a reduced dose.

Abstract
BACKGROUND One-week low-dose triple therapy is currently considered the gold standard regimen for treatment of Helicobacter pylori infection. However, the mechanisms involved in the synergy between antibiotics and proton pump inhibitors are controversial. AIMS To test the hypothesis that acid suppression represents the crucial mechanism by which the antibacterial activity of antibiotics can be enhanced, and to assess the impact of primary resistance on treatment outcome. METHODS One hundred and twenty patients with H. pylori infection and duodenal ulcer, gastric ulcer or non-ulcer dyspepsia were randomly assigned to a 1 week course of either famotidine 80 mg b.d., clarithromycin 250 mg b.d. and metronidazole 500 mg b.d. (FCM group; n = 60) or omeprazole 20 mg o.d., clarithromycin 250 mg b.d. and metronidazole 500 mg b.d. (OCM group; n = 60). Gastroscopy was performed at baseline and 5 weeks after completion of treatment. H. pylori status was assessed by biopsy urease test, histology and culture. RESULTS In the intention-to-treat analysis, eradication of H. pylori was achieved in 47 of 60 patients (78%; 95% CI: 66-88%) in the FCM group, compared to 44 of 60 patients (73%; 95% CI: 60-84%) in the OCM group (N.S.). Using per protocol analysis, eradication therapy was successful in 47 of 52 patients (90%; 95% CI: 79-97%) treated with FCM and 44 of 57 patients (77%; 95% CI: 64-87%) treated with OCM (N.S.). Primary metronidazole resistance was present in 27% and primary clarithromycin resistance in 8% of strains. Overall per protocol eradication rates in strains susceptible to both antibiotics and strains with isolated metronidazole resistance were 93% and 84%, respectively. No patient with clarithromycin resistance responded to treatment. CONCLUSIONS High-dose famotidine and omeprazole, combined with clarithromycin and metronidazole, are equally effective for eradication of H. pylori. In 1-week low-dose triple therapy, metronidazole resistance has no major impact on eradication rates whereas clarithromycin resistance is associated with a poor treatment outcome.

Abstract
OBJECTIVES The combination of a proton pump inhibitor (PPI) such as omeprazole with amoxicillin and clarithromycin constitutes one of the most effective treatments for the eradication of Helicobacter pylori. Nevertheless, the mechanisms of interaction between these drugs remain unclear. It has been shown that minimal inhibitory concentration values of both antibiotics are considerably lower at neutral pH levels than in an acid environment. Further, omeprazole possesses bacteriostatic activity. To evaluate the significance of these mechanisms we replaced omeprazole with famotidine, a drug which only suppresses acid production, but has no intrinsic antimicrobial activity. METHODS We evaluated the efficacy of a 1-week course of famotidine 80 mg b.i.d., amoxicillin 1000 mg b.i.d. and clarithromycin 500 mg b.i.d. in a pilot study (20 patients), and then confirmed our results in a larger replication study (87 patients). A total of 107 patients with H. pylori-associated duodenal ulcer (n = 54), gastric ulcer (n = 14) or non-ulcer dyspepsia (n = 39) were included. Endoscopy was performed at baseline and 4-6 weeks after discontinuation of treatment. H. pylori status was assessed by the urease test and histology. RESULTS H. pylori was successfully eradicated in 94 of 104 patients who completed the study (90.4%; CI 95%, 83.0-95.3%). By intention-to-treat analysis, the eradication rate was 87.9% (CI 95%, 80.1-93.4%). Ulcer healing was observed in 98.1% of duodenal ulcers and 92.9% of gastric ulcers (based on per-protocol analysis). Mild side effects that did not require termination of treatment were reported by seven patients (6.7%). CONCLUSION A 1-week course of famotidine, amoxicillin and clarithromycin is a highly effective, simple and safe eradication regimen. Our data indicate that acid suppression is the crucial mechanism by which the activity of amoxicillin and clarithromycin against H. pylori is enhanced, whereas additional antimicrobial activity or other specific effects of PPIs seem to be less important.

Abstract
BACKGROUND & AIMS In patients with Wilson's disease presenting with liver involvement, the correct diagnosis is often missed or delayed. The aim of this study was to find an algorithm for diagnosis of this difficult patient group. METHODS Clinical and laboratory findings of 55 patients with Wilson's disease were evaluated at diagnosis before treatment. Presenting symptom was chronic liver disease in 17 patients, fulminant hepatic failure in 5 patients, hemolysis in 3 patients, and neurological disease in 20 patients, and 10 patients were detected by family screening (siblings). Evaluation included neurological and ophthalmologic examination, routine laboratory tests, and parameters of copper metabolism including liver copper content in 43 liver biopsy specimens. RESULTS In the whole group, serum ceruloplasmin level was <20 mg/dL in 73%, urinary copper excretion was increased in 88%, and liver copper content was elevated in 91% at diagnosis. Kayser-Fleischer rings were detected in 55%. In contrast to patients with neurological disease (90% Kayser-Fleischer rings, 85% low ceruloplasmin), only 65% of patients presenting with liver disease were diagnosed by these typical findings. Ceruloplasmin levels were lower in patients with Kayser-Fleischer rings or with neurological disturbances than in patients without these symptoms. CONCLUSIONS The commonly used clinical and laboratory parameters are not sufficient to exclude the diagnosis of Wilson's disease in patients with liver disease of unknown origin.

Abstract
BACKGROUND Blood group Lewis(b) antigens mediate Helicobacter pylori attachment to gastric mucosa with attachment being particularly strong in subjects with ABH blood group O. AIMS To determine whether H pylori colonisation or the occurrence of gastric mucosa associated lymphoid tissue (MALT) lymphomas might be related to gastric Lewis(b) expression or occurrence of particular ABH blood groups on gastric mucosa. PATIENTS Gastric resection specimens from 89 cases with gastric MALT lymphoma and gastric mucosal biopsy specimens from 95 patients undergoing upper endoscopy due to upper gastrointestinal complaints, including five cases with gastric MALT lymphoma, were studied. METHODS H pylori was visualised with the Warthin-Starry stain. Immunostaining (Lewis(b), Lewis(a), A, B) was performed by applying a three step immunoperoxidase technique and indirect immunofluorescence staining on formalin fixed and paraffin wax embedded tissue. In 40 patients red blood cell Lewis phenotype and ABH blood groups were additionally determined by haemagglutination assay. RESULTS Gastric surface epithelial cells showed an immunoreactivity to blood groups A, B, and AB in 80 (43.5%), 22 (12%), and 11 (6%) cases respectively and no immunoreactivity to any of these blood group substances (blood group O) in 71 (38.5%) patients. Lewis(b) expression of all gastric surface epithelial cells (secretor status) was found in 130 (70.7%) cases. Lewis(a) expression of all gastric surface epithelial cells (non-secretor status) was found in 36 (19.6%) cases, secretor status remained unclassified in 18 (9.8%) patients. Colonisation with H pylori was found in 134 (72.8%) cases. The occurrence of H pylori was neither significantly associated with secretor status nor with certain ABH blood groups. The infiltration of gastric mucosa with MALT lymphoma was highly significantly associated with H pylori colonisation (p < 0.0003) but neither with secretor status nor with certain ABH blood groups. There was no inter-relation between secretor status or ABH blood groups and type, stage, grade of, and survival after MALT lymphoma. CONCLUSION This study failed to show an inter-relation between secretor status or particular ABH blood groups and either H pylori infection or the occurrence of gastric MALT lymphomas.

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
Recent studies have identified the integrin alpha 4 beta 7 as a mucosal homing receptor that mediates lymphocyte migration to the intestinal mucosa by binding to MAdCAM-1, a vascular recognition molecule (addressin) selectively expressed on mucosal endothelium. In the present study, we have assessed the expression of alpha 4 beta 7 on B- and T-cell non-Hodgkin's lymphomas of different primary localization and on related normal lymphocytes. Among B-lineage lymphomas, expression of alpha 4 beta 7 was present in the majority of cases of malignant lymphomatous polyposis of the intestine and low-grade lymphoma of the mucosa-associated lymphoid tissue/monocytoid B-cell lymphoma and in some cases of precursor B-cell lymphoma. CLL/small lymphocytic lymphoma, (nodal) mantle cell lymphoma, follicular center cell lymphoma, Burkitt's lymphoma, and diffuse large B-cell lymphoma were virtually always alpha 4 beta 7 negative, as was the case when localized in the mucosa-associated lymphoid tissue. The normal B cells of the follicle mantles and part of the B cells of the extrafollicular B-cell compartment of lymphoid tissues expressed moderate levels of alpha 4 beta 7. By contrast, follicular center cells were alpha 4 beta 7 negative. Among T-lineage lymphomas, expression of alpha 4 beta 7 was also strongly related to the primary localization; in mucosal, nodal, and cutaneous T cell lymphomas the percentage of positive cases was 56%, 17%, and 0%, respectively. All cases of precursor T-cell lymphoma were alpha 4 beta 7 negative. High expression of alpha 4 beta 7 was found on a subset of peripheral blood memory T cells as well as on lymphocytes in the intestinal mucosa. We conclude that non-Hodgkin's lymphomas that are related to mucosa-associated B- and T-lymphocyte populations selectively express the mucosal homing receptor alpha 4 beta 7. The presence of this receptor underscores their distinctive character and may play an important role in determining their characteristic mucosal dissemination pattern.

Abstract
Reinfection with Helicobacter pylori after eradication is responsible for the recurrence of duodenal ulcer disease. The mode of transmission has not yet been established. In this study, 18 patients with chronic duodenal ulcers in whom H pylori had been eradicated with amoxicillin and metronidazole were entered into a prospective follow up study. Control endoscopies were performed 4, 8, 14, 27, and 43 months after starting treatment and the results of direct tests were compared with the kinetics of H pylori specific IgG titres. After eradication there was a noticeable and consistent fall in anti-H pylori IgG, while reinfections were characterised by a significant increase in specific titres. Reinfection was detected in two patients after 14 and 43 months, respectively. The H pylori strains responsible for these reinfections, the corresponding pretreatment isolates, and the strains isolated from the spouses of these patients were examined by polymerase chain reaction based DNA fingerprinting. Analysis showed that reinfection had been caused by the same H pylori strain and identified the spouses of these patients as carriers of the identical strain. Considering the genomic diversity and the interpatient heterogeneity of H pylori these results suggest a person to person transmission of H pylori reinfection. By the end of the observation period reflux oesophagitis had developed in 10 of the 16 patients who had not been reinfected. This surprising finding may be explained by the changed eating habits of patients after healing of duodenal ulcer disease.

Abstract
Recent studies have identified the integrin alpha 4 beta 7 as a mucosal homing receptor that mediates lymphocyte migration to the intestinal mucosa by binding to MAd-CAM-1, which is a vascular recognition molecule (adressin) selectively expressed on mucosal endothelium. The expression of the alpha 4 beta 7 mucosal homing receptor was studied in eight cases of malignant lymphomatous polyposis (MLP). This unusual presentation of non-Hodgkin's lymphoma of mantle cell type is characterized by multifocal lymphomatous involvement of the gastrointestinal tract. Unlike nodal mantle cell lymphomas, cases of MLP showed expression of alpha 4 beta 7, suggesting that this homing receptor plays an important role in determining the characteristic mucosal dissemination pattern of MLP.

Abstract
A total of 104 patients with recurrent duodenal ulcer were treated with either ranitidine plus amoxicillin plus metronidazole or ranitidine plus placebo. To study the effect of the eradication of Helicobacter pylori on the systemic immune response in an IgG ELISA, sera were drawn from all patients before the onset of therapy and at 6, 16 +/- 2, 32 +/- 2, and 60 +/- 2 weeks after therapy. In patients with eradication of the organism, a significant (P < .001) reduction of the specific IgG titer occurred. This was not observed in patients without bacterial eradication. If a titer reduction of > 50% was taken as an indicator for eradication of H. pylori, the sensitivity of the serologic test was 97.6%-99.7%. Its specificity increased with the interval to the onset of chemotherapy from 56.3% to 97.6%. Serologic tests are simple to perform and cause very little discomfort to the patient.

Abstract
BACKGROUND Persistent infection with Helicobacter pylori is associated with the recurrence of duodenal ulcer. Whether the efficacy of bismuth therapy in reducing the rate of recurrence of duodenal ulcer is due to its antimicrobial effects on H. pylori or to a direct protective action on the mucosa is still a matter of debate. METHODS To study the effect of the eradication of H. pylori on the recurrence of duodenal ulcer, we treated 104 patients with H. pylori infection and recurrent duodenal ulcer with either amoxicillin (750 mg three times daily) plus metronidazole (500 mg three times daily) or identical-appearing placebos, given orally for 12 days. All patients also received ranitidine (300 mg each night) for 6 or 10 weeks. Endoscopy was performed before treatment and periodically during follow-up for up to 12 months after healing. RESULTS Among the 52 patients given antibiotics, H. pylori was eradicated in 46, as compared with 1 of the 52 given placebo (89 percent vs. 2 percent, P < 0.001). After six weeks, the ulcers were healed in 48 patients given antibiotics and 39 given placebo (92 percent vs. 75 percent, P = 0.011). Side effects, mainly diarrhea, occurred in 15 percent of the patients given antibiotics. Among the patients followed up for 12 months, duodenal ulcers recurred in 4 of 50 patients given antibiotics and 42 of 49 given placebo (8 percent vs. 86 percent, P < 0.001). Ulcers recurred in 1 of 46 patients in whom H. pylori had been eradicated, as compared with 45 of 53 in whom H. pylori persisted (2 percent vs. 85 percent, P < 0.001). CONCLUSIONS In patients with recurrent duodenal ulcer, eradication of H. pylori by a regimen that does not have any direct action on the mucosa is followed by a marked reduction in the rate of recurrence, suggesting a causal role for H. pylori in recurrent duodenal ulcer.

Abstract
Twenty-seven cases of primary peripheral T-cell lymphomas of the intestine (PTLI) were investigated. Seven patients had histories of malabsorption. The most frequent symptoms at presentation were weight loss, abdominal pain, and acute abdomen. The jejunum was the most common site of lymphoma and multifocal disease was found in 72% of the cases. Twenty-two patients (92%) presented with localized disease confined to the intestine and abdominal lymph nodes, only two patients had generalized disease. According to the pattern of lymphoma infiltration and the morphology of the uninvolved small intestinal mucosa, 21 cases were separated histologically into three categories; 1) enteropathy-associated T-cell lymphoma (EATCL, n = 9) showing predominant intramucosal lymphoma spread and villous atrophy of uninvolved mucosa with high density of intraepithelial lymphocytes (IEL), 2) EATCL-like lymphoma without enteropathy (EATCL-LLWE, n = 5) but with an infiltration pattern similar to EATCL, and 3) T-cell lymphoma without features of EATCL (Non-EATCL, n = 7). Distinctive features of EATCL were the high incidence of malabsorption states, multifocal intestinal disease in all cases, and the high frequency of intestinal recurrences. On frozen sections four of eight PTLI showed the phenotype CD3+ CD4- CD8- HML-1+, which is also expressed on a small subset of normal IEL. The morphologic and immunomorphologic findings suggest that the majority of PTLI is derived from mucosal T lymphocytes. This derivation may be responsible for certain biologic features, such as the preferential spread to and relapse of PTLI at small intestinal sites.

Abstract
Three hundred seven cases (244 gastric, 63 intestinal) of primary gastrointestinal non-Hodgkin's lymphoma (NHL) in stages EI and EII, according to a modified Ann Arbor system, were examined retrospectively. The histological classification for mucosa-associated lymphoid tissue-derived lymphomas was applied. Gastric NHLs (male-female ratio, 0.97; mean age, 64.5 years) were stage EI in 51% and stage EII in 49% of cases. Histological grade of malignancy was low in 41% and high in 59% of cases; all NHLs were B-cell type. Tumors were radically resected in 87%, and overall 2-, 5-, and 10-year survival rates were 61%, 55%, and 46%, respectively. Early lymphomas (substage EI1) had best prognosis (5- and 10-year survival rates, 90% and 70%, respectively). Intestinal NHLs (male-female ratio, 1.1; mean age, 54.4 years) were stage EI in 30% and stage EII in 70% of cases. Histology was low grade in 21% and high grade in 79%, and all but 11 cases were B-cell type. In 58% of cases, radical tumor resection resulted in overall 2- and 5-year survival rates of 44% and 24%, respectively. Major prognosticators for survival in gastric location were low-grade histology, low depth of infiltration, and low stage and radical resectability of lymphoma; all factors were strictly intercorrelated. In intestinal site, radical tumor resectability was highly significant for survival. Cumulative proportion of relapses after 5 years was higher in intestinal than in gastric sites (44% vs. 22%). In conclusion, primary gastrointestinal tract NHLs may represent an entity with respect to characteristic histological features, focal tumor growth, and potential cure by radical resection. Because of late relapses, clinical follow-up is needed.

Abstract
Silymarin, the active principle of the milk thistle Silybum marianum, protects experimental animals against various hepatotoxic substances. To determine the effect of silymarin on the outcome of patients with cirrhosis, a double blind, prospective, randomized study was performed in 170 patients with cirrhosis. 87 patients (alcoholic 46, non-alcoholic 41; 61 male, 26 female; Child A, 47; B, 37; C, 3; mean age 57) received 140 mg silymarin three times daily. 83 patients (alcoholic 45, non-alcoholic 38; 62 male, 21 female; Child A, 42; B, 32; C, 9: mean age 58) received a placebo. Non-compliant patients and patients who failed to come to a control were considered as 'drop outs' and were withdrawn from the study. All patients received the same treatment until the last patient entered had finished 2-years of treatment. The mean observation period was 41 months. There were 10 drop outs in the placebo group and 14 in the treatment group. In the placebo group, 37 (+2 drop outs) patients had died, and in 31 of these, death was related to liver disease. In the treatment group, 24 (+4 drop outs) had died, and in 18 of these, death was related to liver disease. The 4-year survival rate was 58 +/- 9% (S.E.) in silymarin-treated patients and 39 +/- 9% in the placebo group (P = 0.036). Analysis of subgroups indicated that treatment was effective in patients with alcoholic cirrhosis (P = 0.01) and in patients initially rated 'Child A' (P = 0.03). No side effects of drug treatment were observed.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Two hundred forty-two voluntary blood donors, referred after detection of HBsAg positivity, underwent clinical evaluation and liver biopsy and were prospectively followed for an average of 3.5 years. At initial testing, 65% of HBsAg carriers had normal laboratory findings; during follow-up, 26% of these carriers developed abnormal test results, at least transiently. Liver histology was normal in 31.4%, revealed nonaggressive liver disease in 63.6% and chronic active hepatitis or cirrhosis in 5%, only. All except one case of chronic active hepatitis or cirrhosis were associated with abnormal blood biochemical tests. Sequential liver biopsies obtained in 56 HBsAg carriers after a minimal interval of 4 years showed mitigation of inflammatory changes in 5.4% and developing chronic active hepatitis in three cases (5.4%). One carrier died of primary hepatocellular carcinoma. Upon follow-up, HBsAg persisted in 98%. Anti-HBe was found in 90% of all carriers already at the initial testing. HBeAg positivity (7.5%) was associated with chronic active hepatitis as well as nonaggressive liver disease; clearance of HBeAg occurred in 40% after 2 to 8 years. Because of the subclinical progression of liver disease and the increased risk for developing primary hepatocellular carcinoma in asymptomatic HBsAg carriers, routine blood testing, including alpha-fetoprotein screening, as well as abdominal ultrasound surveillance are indicated. Liver biopsy, however, should be restricted to carriers with abnormal biochemical findings.

Abstract
Polypoid lesions of the colon are commonly accepted risk factors for the development of carcinomas of the colon. Fifty-two of 266 patients with one or more polypoid lesions of the colon showed a carcinoma in one of the polyps, 6 patients had a second carcinoma. Our study demonstrates the importance of preoperative investigation of the total colon in patients with carcinoma of the colon. Furthermore, the necessity of total exstirpation of each polypoid lesion is discussed.

Abstract
The records of 150 primary gastrointestinal (GI) lymphomas in adults collected from 1974 to 1982 at the Department of Pathology, University of Vienna, were reviewed. One hundred thirty-three cases of malignant lymphomas (ML) were analyzed with respect to histologic type, presenting tumor stage, and clinical course, as well as for factors influencing prognosis. The histologic type of ML as assessed by the Working Formulation and the Kiel, the Lukes and Collins, and the Rappaport classifications showed only a minor influence on prognosis. MLs of follicular center cell origin prevailed in the stomach and large cell, immunoblastic MLs prevailed in the bowel. Immunoperoxidase studies indicated a B-cell nature of GI MLs and demonstrated intracytoplasmic IgM kappa or lambda in most of the MLs of the small lymphocytic, plasmacytoid, and immunoblastic type, respectively. The 105 cases of gastric MLs represented 3.6% of all malignancies of the stomach collected during the study period. Clinical symptoms preceded the diagnosis by 4.4 months on average, and endoscopic biopsy specimens indicated malignancy in 78%. Presenting tumor stages of gastric MLs according to the Ann Arbor staging system were Stage I in 20%, Stage II in 76.2%, and Stage IV in 3.8%. The 28 cases of intestinal ML localized in the small and large bowel without any site prevalence presented with Stage I in 14%, Stage II in 82%, and Stage III in 4%. Tumor resection was performed in 90% of all cases and was followed by multiagent therapy in 53%. Radical tumor resection was obtained in 58% of the gastric MLs and only 28.6% of the intestinal MLs and was closely related to tumor stage. Statistical analysis demonstrated a significant influence of the presenting tumor stage on prognosis as expressed by the overall 2-year survival rate of 70% for Stage I versus 39% for Stage II ML. In addition, Stage II1 according to Musshoff et al. run a better course than II2 as shown by the disease-free 2-year survival rate of 49% versus 15%, respectively. Radical tumor resection was a major determinant of survival and cure of disease as exhibited by the disease-free 2-year survival rate of 57% after radical resection versus 8% after nonradical resection of ML. Finally, diffuse tumor growth and tumor penetration of the gastric wall beyond serosa decreased the survival rates.

Abstract
A 57 year old female patient suffered from Raynaud's syndrome and relapsing necrotizing lesions of the finger tips. Diagnosis of sclerodermia was established by angiography and biopsy. A spotty brownish coloration of the skin and cirrhosis of the liver were observed in addition. Clinical chemistry showed increased alkaline phosphatase and increased titers of antimitochondrial antibodies. Histology of liver tissue was compatible with a diagnosis of primary biliary cirrhosis. After a course of several years a Sicca syndrome appeared. On investigation of family members an increased incidence of positive antinuclear and antimitochondrial antibodies was found. The patient has now been followed for 5 years. Prognosis may be considered to be good.

Abstract
70 patients with established diffuse liver disease (steatosis, fibrosis, cirrhosis) were investigated by sonography and scintigraphy. Sonographic parenchymal morphology and scintigraphic activity pattern were correlated with the histological diagnosis. Scintigraphy as a functional diagnostic technique revealed early fibrotic changes of the liver not seen by ultrasound. Cirrhosis could be demonstrated equally by both methods. The two major advances of ultrasound were: high accuracy in steatosis and ability of simultaneous analysis of the other abdominal organs.

Abstract
The incidence of primary liver cancer (PLC) was assessed in 652 patients (429 male, 223 female) with liver cirrhosis. By the end of the study 416 (64%) of all patients had died. The autopsy rate was 65%. PLC developed in 73 patients. Histologically, 67 cases were classified as hepatocellular (HCC), one as mixed hepatocellular-cholangiocellular and five as cholangiocellular carcinoma. In 30 cases, HCC was confirmed within a year of diagnosis of cirrhosis, and in the remaining 37 cases HCC developed 2-13 years later. At autopsy, the frequency of HCC was almost twice as high in males (27%) as in females (15%) (p less than 0.025). This difference occurred in alcoholic and posthepatitic cirrhosis but not in cryptogenetic cirrhosis. HBsAg was detected in 19.0% of male and 9.2% of female patients (p less than 0.01). Comparison of patients with and without HCC revealed no significant differences in the prevalence of HBsAg. These data indicate that HCC is common in Austrian patients with cirrhosis, representing 60% of all malignant tumors in this group. In view of the high HBsAg carrier rate and the prevalence of chronic alcoholism in patients with cirrhosis, it is suggested that the two factors together lead to an increased risk of cirrhosis followed by an increased incidence of HCC.

Abstract
In 11 female patients with primary biliary cirrhosis, clinical and or electrophysiological signs of a polyneuropathy were found in 9 cases. 8 patients had clinical and 7 patients electrophysiological signs of a polyneuropathy. We derive from the significant correlations between neurographic and metabolic parameters that a hepatic disorder, a disorder of lipid and protein metabolism strongly contribute to the development of polyneuropathy in primary biliary cirrhosis.

Abstract
The incidence of primary liver cancer (PLC) was assessed in 652 patients (429 male, 223 female) with liver cirrhosis. By the end of the study 64% of all patients had died. The autopsy rate was 65%. 138 patients (49%) died after acute gastrointestinal hemorrhage. PLC developed in 73 patients (11.3%). Histologically 67 cases were classified as hepatocellular, one as mixed hepatocellular-cholangiocellular, and 5 as cholangiocellular carcinoma. In 32 cases PLC was confirmed within a year of diagnosis of cirrhosis, while in the remaining 41 cases PLC developed 2 to 13 years later. At autopsy the frequency of PLC was twice as high in males (30%) as in females (15%) (p less than 0.025). This difference occurred in alcoholic and posthepatic cirrhosis but not in cryptogenetic cirrhosis. HBsAg was detected in 18.5% of male and 8.9% of female patients (p less than 0.01). Comparison of patients with and without PLC revealed no significant differences in the prevalence of HBsAg. These data indicate that PLC is common in Austrian patients with cirrhosis and represents 64% of all malignant tumors in this group. In view of the high HBsAg carrier rate and the prevalence of chronic alcoholism in patients with cirrhosis, it is suggested that both factors together lead to an increased risk of cirrhosis followed by an increased incidence of PLC. Survival curves show that that the prognosis of severe liver cirrhosis is the same as that of patients with malignant diseases. Therefore, it is important to detect these patients at an early stage of the disease.

Abstract
The behaviour of prekallikrein (PKK), factor XII, high molecular weight kininogen (HMWK) and kallikrein-inhibitor (KK-I) in 367 patients with various diseases is described. Malignancies lead to elevation of factor XII and KK-I, and reduction of PKK. The effect is more pronounced in patients with metastases. In renal diseases also one or more of the above mentioned parameters are abnormal. Defects requiring dialysis treatment significantly impair the contact factors. In this group low levels of PKK, Factor XII and HMWK and increased KK-I are common. In chronic renal disease patients, only F XII and KK-I are elevated, whereas PKK and HMWK are normal. Kidney transplantation leads to a rise in KK-I and reduction of PKK and HMWK. The values almost normalize few days after the operation. Factor XII, slightly increased immediately after transplantation, remains high in long term transplant recipients, whereas HMWK falls below normal. In liver disease patients, acute and chronic hepatitis, cirrhosis of the liver and coma, PKK is reduced. In cases with acute hepatitis PKK raises with recovery. Cirrhosis and coma lead to low HMWK and factor XII concentrations. KK-I is mostly affected during acute hepatitis, and is then highly increased. Our results clearly demonstrate that the biologic activity of one or more of contact factors is affected in many diseases.

Abstract
A report is given about emergency endoscopy in 389 patients because of bleeding from the upper gastrointestinal tract; 60 of these patients had cirrhosis of the liver as confirmed by biopsy. In the total group 17.4% were found to have bleeding from esophagus varices, in the cirrhotic group the incidence was 53%. Erosive lesions of the stomach came second in incidence, accounting for 27% of the cases in the latter group. In 60% of patients with cirrhosis, who had had acute bleeding, esophageal varices were present in abundance, whereas only 27% of patients without bleeding did have such excessive formation of varices. Thrombotest and thrombocyte count were equal in both groups. In 50% of 133 patients with cirrhosis of the liver without acute bleeding complications, a second potential source of bleeding beside esophageal varices could be detected. This underlines the importance of emergency endoscopy in patients with cirrhosis of the liver suffering from acute upper gastrointestinal bleeding.

Abstract
The case of a 51 years old man with a hepatocellular carcinoma (HCC) is reported. Though the tumor is of multifocal origin and widespread the disease takes a favourable course. Histology revealed a well differentiated HCC with clusters of polygonal tumor cells and fibrous stroma, the pattern of which reminds of focal nodular hyperplasia (FNH). HCC has developed in a non cirrhotic liver. Clinically, the patient is in a good condition 22 months after diagnosis of the tumor. The value of all possible methods--invasive and not invasive--for diagnosis of HCC is assessed and compared with literature. According to the literature the survival time comes to 3 to 6 months on average, only single cases take a more favourable course. Correlation of morphology and biological behaviour of tumor is lacking. In our case the pattern of fibrosis similar to FNH is striking and points to a development of carcinoma in preexisting FNH. In literature, however, evidence for a malignant transformation of FNH is lacking.

Abstract
Administration of high doses of 131I-6 beta-iodocholesterol to rabbits is followed by marked size reduction of the adrenal glands with concomitant changes of the histological structure and with a decrease of serum cortisol. Stimulation of 131I-6 beta-iodocholesterol uptake into the adrenals by additional administration of ACTH had only a minor additional effect on adrenal weight. However, with further accumulation of labeled cholesterol in the adrenals the radioactivity was reduced in blood urine, and the ovaries.

Abstract
The effect of protease pretreatment on the demonstration of hepatitis-B-surface antigen by immunofluorescence (IF) and the unlabeled peroxidase-antiperoxidase technique (PAP) in conventionally processed (formalin-fixed, paraffin-emmbedded) liver biopsy material was quantitatively assessed by microphotometry. Protease digestion significantly enhances the intensity of specific staining by both methods, and, in addition, suppresses non-specific background fluorescence. The sensitivity of the immunomorphologic test is significantly enhanced, and antigen in low amounts, for example hepatitis-B-surface antigen associated with liver cell membrane ('membrane' staining), is easily detected.

In 241 paraffin-embedded liver-biopsies of HBSAg-positive, voluntary blood-donors hepacellular HBSAg was demonstrated with the immunomorphologic peroxidase-antiperoxidase (PAP)-method. In all sections, HBSAg-positive liver-cells were estimated, their distribution-pattern was assessed and different types of cytoplasmatic localisation of HBSAg were described. Despite high sensitivity of the PAP-method, 24% of seropostive cases were histologically negative. A correlation of HBSAg-content and histologic diagnosis was lacking. An association of high HBSAg-content with non-aggressive liver-disease and of low HBSAg-content with aggressive liver-disease in a single biopsy could not be found in our material in contrast to the literature. 34 patients were followed up through 4-6 years. Constant or improved liver-histology was associated with increased, deterioration with decreased HBSAg-tissue-content.
