Abstract
Antinuclear antibodies were significantly more prevalent (p less than 0.01) in 143 patients with alcoholic cirrhosis than in 64 patients with alcoholic steatosis and in 94 controls. Smooth muscle antibodies were significantly more prevalent (p less than 0.05) in patients with alcoholic steatosis and cirrhosis than in controls. The prevalence of antimitochondrial antibodies and IgG liver membrane antibodies did not differ significantly between the three groups. Immunoglobulin G, A, and M concentrations were only occasionally increased in patients with steatosis. Patients with cirrhosis had significantly increased (p less than 0.005) concentrations of immunoglobulins G, A, and M when compared to patients with steatosis. These results indicate that the degree of liver damage has more effect than chronic alcoholism on the humoral immune system. Whether this influence is direct or indirect remains to be established.

Abstract
PURPOSE We assessed the risk of hospitalization for upper gastrointestinal bleeding among patients using systemic corticosteroids, accounting for the use of other drugs that may increase the risk of bleeding. SUBJECTS AND METHODS We conducted a population-based cohort study in North Jutland County, Denmark. Data on the use of corticosteroids, nonsteroidal anti-inflammatory drugs, aspirin, and anticoagulants during 1991 to 1995 were obtained from a countywide prescription database. All hospitalizations because of upper gastrointestinal bleeding were identified through the Hospital Discharge Registry. The observed numbers of patients with gastrointestinal bleeding in various exposure categories among corticosteroid users were compared with the expected number based on the North Jutland population who did not receive prescriptions for any of the drugs under study. RESULTS A total of 45,980 patients accrued 18,379 person-years of corticosteroid use. There were 109 hospital admissions for gastrointestinal bleeding among corticosteroid users, compared with 26 expected, yielding a relative risk of 4.2 [95% confidence interval (CI): 3.4 to 5.0]. Among corticosteroid users who did not use other drugs associated with gastrointestinal bleeding, the relative risk was 2.9 (95% CI: 2.2 to 3.7). The relative risk decreased further to 1.9 (95% CI: 1.4 to 2.5) when current corticosteroid usage was compared with former usage. CONCLUSION We observed an increased risk of hospitalization because of upper gastrointestinal bleeding among patients prescribed corticosteroids, especially among those who use other medications. Confounding from the underlying disease may also have contributed to the observed increase in risk.

Abstract
We examined the risk of bacteremia in patients with liver cirrhosis (compared with the risk for all Danish citizens >20 years of age who were living in North Jutland County, Denmark), as well as the type of bacteremia and the 30-day case-fatality rate. We used the Danish National Registry of Patients to identify 1339 patients with liver cirrhosis, and we used the North Jutland County Bacteremia Database to identify episodes of bacteremia. We observed 117 cases of bacteremia in patients with liver cirrhosis (11.0 cases were expected), which yielded a standardized incidence ratio of 10.5 (95% confidence interval [CI], 8.8-12.7). Sixty-two cases of bacteremia were nosocomial infections. There were 53 cases of gram-positive bacteremia, 55 cases of gram-negative bacteremia, and 8 cases of polymicrobial bacteremia (1 case of candidemia was excluded from the analysis). The most common cause of death was bleeding from gastroesophageal varices; the second most common cause of death was infection in the respiratory system. The 30-day case-fatality rate was 0.53 (95% CI, 0.39-0.73). Patients with liver cirrhosis had an increased risk of bacteremia and a poor prognosis.

Abstract
Primary sclerosing cholangitis (PSC) predisposes to cholangiocarcinoma (CC). PET scanning can assess metabolism in vivo. The glucose analogue [18 F]fluoro-2-deoxy-D-glucose (FDG) accumulates in malignant tumours because of high glucose metabolism. PET scanning of the liver was performed after intravenous FDG in nine patients with PSC, six with PSC + CC, and five controls. "Hot spots" with radioactivity accumulation were seen in each PSC + CC patient, but not in the two other groups. Values of net metabolic clearance of FDG, K (ml min-1 100 ml-1 tissue), was in CC hot spots 1.59 to 4.17 (median, 2.34; n = 6); in reference liver tissues of these patients 0.40 to 0.69 (0.49); in PSC 0.23 to 0.53 (0.36); in controls 0.20 to 0.34 (0.31). The difference between K in CC hot spots and the other groups was statistically significant (P < 0.001). FDG-PET may detect small CC tumours and be useful in therapeutic management of PSC.

Abstract
AIM To assess the safety of proton pump inhibitors during pregnancy. METHODS Fifty-one pregnant women exposed to proton pump inhibitors around the time of conception or during pregnancy were compared with 13 327 controls without exposure to any prescribed drug in a population-based study based on The Pharmaco-Epidemiological Prescription Database of North Jutland and the Danish Hospital Discharge Registry. RESULTS Three babies with malformations were found among 38 women exposed to proton pump inhibitors from 30 days before conception to the end of the first trimester. No cases of stillbirth were recorded. Crude relative risks of malformation, low birth weight and preterm delivery were 1.6 (95% CI: 0.5-5.1), 1.8 (95% CI: 0.2-13.0) and 2.3 (95% CI: 0.9-6.0), respectively. CONCLUSIONS In this population-based follow-up study, we found no substantially elevated risk in terms of malformations, low birth weight or number of preterm deliveries in pregnancies exposed to proton pump inhibitors. However, further monitoring is warranted in order to establish or rule out a potential association between the use of proton pump inhibitors and increased risk of either cardiac malformations or preterm birth.

Abstract
Primary sclerosing cholangitis (PSC) predisposes to cholangiocarcinoma (CC), which usually is widespread in the liver at the time of the diagnosis and which has a median survival of approximately 6 months. Positron emission tomography (PET) is a noninvasive scanning method that allows the assessment of metabolism in vivo by means of positron-emitting radiolabeled tracers. [18F]Fluoro-2-deoxy-D-glucose (FDG) is a glucose analogue that accumulates in various malignant tumors because of their high glucose metabolic rates. The purpose of the study was to develop a PET method to detect small CC tumors in patients with PSC. PET scanning of the liver was performed after intravenous injection of 200 MBq FDG in 9 patients with PSC, 6 patients with PSC + CC, and 5 controls. The scanning was performed at successive time intervals for a total of 90 minutes with simultaneous successive arterial blood sampling for radioactivity concentration determination. In each of the PSC + CC patients, 2 to 7 "hot spots" were seen, with volumes of 1.0 to 45 mL (median, 4.4 mL). There were no hot spots in the two other patient groups. The localization of hot spots was confirmed by single-blind evaluation. Data were analyzed by the Gjedde-Patlak plot, yielding values of the net metabolic clearance of FDG, K [mL min(-1) 100 mL(-1) tissue]. In the CC hot spots, maximum K values were 1.59 to 4.17 (median, 2.34; n = 6); in the reference liver tissues of these patients, K values were 0.40 to 0.69 (median, 0.49); in PSC patients, they were 0.23 to 0.53 (median, 0.36); and in controls, they were 0.20 to 0.34 (median, 0.31). The difference between K in CC hot spots and the other groups was statistically significant (P < .001). We conclude that FDG-PET seems to be able to detect small CC tumors and may be useful in the therapeutic management of PSC.

Abstract
BACKGROUND Many patients with chronic hepatitis C have long periods of normal or near-normal liver enzyme levels, even though histologic alterations have been confirmed. The recommendation today is not to treat this patient group. METHODS In a pilot study 23 hepatitis C virus (HCV) RNA-positive patients with alanine aminotransferase (ALAT) levels less than 1.5 times upper normal limits for at least 6 months on more than three occasions and with histologic liver abnormalities compatible with chronic hepatitis C were treated with 3 MU of interferon-alpha 2b three times a week for 6 months. RESULTS Nine patients (39%) became HCV RNA-negative in serum during treatment, but only two (8.7%) remained so after 6 months' follow-up. Significantly more patients with genotype other than type 1 became HCV RNA-negative than patients with genotype 1 during treatment (P = 0.005). CONCLUSIONS Patients with low-activity chronic hepatitis C have a response to interferon-alpha treatment similar to that of patients with increased ALAT levels. Genotype seems to influence the rate of response.

Abstract
BACKGROUND Abdominal pain is often variable in intensity and difficult to characterise due to its referred pain pattern. Clinical pain is furthermore confounded by various emotional and cognitive factors. AIMS To develop and apply an experimental model to induce localised gastric pain. SUBJECTS Twelve healthy male volunteers. METHODS Stimulating electrodes were mounted on a biopsy forceps and electric stimuli were delivered during gastroscopy. Single, five repeated, and continuous stimuli were given at four locations in the stomach. Pain detection thresholds and pain intensities were assessed together with localisation of the referred pain area. RESULTS Pain detection thresholds were higher in the prepyloric region compared with those obtained at the lesser and greater curvature. Increasing stimulus intensity resulted in augmented pain perception and repeated stimuli elicited pain at a lower stimulus intensity than single stimuli. Continuous stimuli evoked constant (33%), increasing (33%), or decreasing (33%) pain. The localisation of referred pain varied considerably in the subjects. CONCLUSIONS The model seems relevant to study basic pain mechanisms elicited by localised stimuli in the stomach. The experimental data support the premise that a gastric focus should always be suspected in patients referred with different kinds of abdominal pain.

Abstract
BACKGROUND Only a few studies have attempted to determined the prevalence of long-standing abnormal liver function and primary sclerosing cholangitis (PSC) in patients with Crohn's disease (CD). The aim of the study was to determine the prevalence of long-standing abnormal liver function test results and to describe the clinical, biochemical, and histologic findings in patients with large-duct classic PSC and small-duct PSC (that is, normal cholangiogram) in patients with CD during a 15-year period. METHODS Patients with CD and long-standing abnormal liver function results were investigated individually with endoscopic retrograde cholangiography and liver biopsy. RESULTS Of 262 consecutive patients with CD, 38 (15%) had long-standing increased alkaline phosphatase (ALP) values (mean, 1065 U/l; range, 321-4165 U/l). Of these, 10 patients were classified as having hepatic disease (4%), of which 9 had PSC and 1 had a non-specific reactive hepatitis. Of nine patients with PSC (3.4%), three were classified as having large-duct PSC; five, small-duct PSC; and one, unclassified. In patients with large-bowel CD (n = 102) the prevalence of PSC was 9%. Mean age at diagnosis of PSC was 35 years (22-46 years), and the female to male ratio, 7:2. All PSC patients had large-bowel involvement (P < 0.00015), and two of them developed colonic carcinoma of the large bowel (P < 0.01). All cases of small-duct PSC were stage 1, whereas large-duct PSC were stage 2-3. During the observation period (mean, 5.4 years) no PSC patients died. CONCLUSIONS The results of our study indicate that PSC is the major hepatic disease in patients with CD and long-standing abnormal liver function tests and is approximately as prevalent as in ulcerative colitis. Patients with PSC and CD may have a milder liver disease than patients with PSC and ulcerative colitis, perhaps because large-duct PSC is less common in patients with CD. Cholangiograms and liver biopsies are both needed to evaluate the extent of the disease.

Abstract
Clinical and biochemical data were collected prospectively from 8032 jaundiced patients to form a database as part of a EU-supported project on computer-aided diagnosis. Patients were recruited prospectively from centres in all EU-countries and some other countries as well. Five hundred and twenty-eight jaundiced patients were collected from four centres in Denmark. Alcoholic cirrhosis, acute alcoholic liver disease and malignancy of the pancreas or the biliary tract were more common in the Danish data base: 49% of cases in Denmark as compared to 30% of cases in the international database. Viral hepatitis was underrepresented in Denmark, 16% as compared to 23% in the international group. A crude Bayesian diagnostic programme on the total database with 17 diagnostic groups achieved 63% accuracy. For the 528 Danish cases the diagnostic accuracy was 64% when the European data base was used, whereas it increased to 81% when only the Danish data base was taken as basis for the calculations. In conclusion, we found a drop in diagnostic accuracy for the Danish patients when using the large European data base instead of the national one.

Abstract
Based on recent reports concerning the efficacy of N-acetylcysteine (NAC) in paracetamol (acetaminophen) poisoning, guidelines for treatment and control of these patients are reviewed by a study group under the Danish Association for the Study of the Liver. It is recommended that NAC-treatment is initiated immediately after referral and continued for 36 hours in all cases. Further NAC-treatment should not be discontinued before a decrease in INR has been observed.

Abstract
A case of acute hepatitis B infection in a 43 year-old male is presented. Seven months before admission the family had adopted a two year-old boy from India, and the child was later found to be seropositive for HBsAg. The patient had no other risk factors of hepatitis B infection and transmission of hepatitis B virus from the adopted child is suspected. It is recommended that children who are adopted from countries with high hepatitis B virus prevalence should be examined for HBsAg, and adoptive family members be vaccinated if the child is found to be HBsAg seropositive.

Abstract
The aim of the study was to determine the prevalence of primary sclerosing cholangitis (PSC) in a regional population of patients with ulcerative colitis (UC). Three hundred and five patients with UC followed over a 12 year period were examined for elevations of serum alkaline phosphatase (> 280 U/l). Twenty four such patients were found. If no cause of these elevations were found by initial investigations, endoscopic retrograde cholangiography was performed in order to determine whether they had PSC. Eleven patients were found to have PSC (3.6%), of whom five had progressive disease, including two deaths from cholangio-carcinoma, during a six-year observation period. We found no certain relation between the extent, duration or activity of ulcerative colitis and the presence of PSC. Alkaline phosphatases were elevated up to 3.7 times the upper reference level, the aminotransferases were only found to be mildly elevated.

Abstract
The prevalence of primary sclerosing cholangitis (PSC) in patients with ulcerative colitis (UC) attending the Depts. of Medical and Surgical Gastroenterology, Aalborg Hospital, during a 12-year period, was determined. All patients with an alkaline phosphatase (ALP) value above the normal range were investigated. Of 305 patients with UC, 24 patients had elevated ALP values, and 11 of these (3.6% of the study population), 4 males and 7 females, were found to have PSC by direct cholangiography. In five patients the disease worsened (two patients died of cholangiocarcinoma), in four it was stationary, and in two patients the disease improved during a mean observation period of 6 years. No differences in location of disease, disease activity, or duration of disease were found between patients with UC and PSC and patients with UC without PSC. The ALP values were raised to a mean of 3.7 times the upper normal limit (observed range, 1.5-5.5 times the upper normal limit). Aspartate aminotransferase was moderately elevated in most patients, but no other abnormal biochemical liver test results were observed at onset. The results of our study indicate that PSC is the major cause of raised ALP values in patients with UC; thus cholangiography should be performed in UC patients with unexplained elevated ALP levels. A prognostic indicator is needed to predict the individual prognosis and to determine the optimal timing of liver transplantation.

Abstract
A retrospective study concerning ten patients with autoimmune hepatitis (AiH), diagnosed during a 2 1/2-year period is presented. The age of the patients ranged from 25 to 82 years and nine of the patients were women. Their symptoms included jaundice, pruritus, fever, anorexia and fatigue during a few weeks to years. Seven patients had increased serum aspartate aminotransferase (ASAT) levels. The three patients with normal ASAT levels had hypoalbuminaemia, decreased level of prothrombin or high levels of serum immunoglobulin G. Moderate or high levels of smooth muscle antibody titer were detected in nine patients, while none had increased levels of anti-nuclear antibody titer. Histological features of moderate or severe chronic active hepatitis were demonstrated in nine patients. One patient presented with clinical and histological features of acute hepatitis. Prednisolone therapy was followed by biochemical improvement in all the patients. In one patient, maintenance therapy with prednisolone was combined with azathioprine.

Abstract
Primary sclerosing cholangitis (PSC) is an uncommon disorder of unknown etiology, characterized by chronic inflammation and fibrosis of the intra- and extrahepatic bile ducts. PSC is commonly associated with chronic inflammatory bowel disease, especially ulcerative colitis, and often in younger men with an extensive colitis. The diagnosis is made by endoscopic retrograde cholangiography. The characteristic findings are multiple strictures and dilatations of the intra- and extrahepatic bile ducts. Patients with PSC usually have a cholestatic biochemical profile. The liver biopsy findings are often non-specific. Different survivals in these patients have been described. However, asymptomatic patients seems to have a more favorable prognosis. The only curative treatment is liver transplantation.

Abstract
To investigate the course of postprandial lipid solubilization in nine patients with chronic, alcoholic pancreatitis, luminal contents were aspirated from the proximal part of the jejunum for 180 min after a meal containing 1.5% fat. Six of the patients had pancreatic insufficiency, whereas three patients were without insufficiency. pH was measured continuously at two sites: at the level of the papilla of Vater and the aspiration site. The fraction of bile acids in the micellar phase of the jejunal aspirates correlated positively to both pH in the aspirates (p less than 0.05) and the fraction of fat solubilized (p less than 0.02). pH was below 4.0 for a longer period of time in the patients with insufficiency, compared to the patients without. However, pH fluctuated rapidly, and there was no correlation between the continuously measured values at the aspiration site and values in the aspirates. Lipid solubilization was not correlated to the lipase activity in the aspirates. We conclude that acidic bile acid precipitation most likely plays a dominant role in the pathophysiology of pancreatic steatorrhea although the methods available are too crude to disclose the precise course of events.

Abstract
Circulating noradrenaline is increased in patients with cirrhosis, especially in decompensated patients with ascites. Eighty-one patients with alcoholic cirrhosis were followed for up to 8 years in order to establish a possible relationship between plasma catecholamines, haemodynamics, and routine clinical and biochemical variables and survival. Forty-seven (58%) of the patients died during the follow-up period. Univariate analysis showed that plasma noradrenaline and adrenaline concentrations, portal pressure, indocyanine green clearance, serum sodium, bilirubin, and albumin concentrations, and the presence of ascites or cardiovascular disease were of significant prognostic value. In a multivariate analysis (Cox regression model), plasma noradrenaline concentration, portal pressure, serum bilirubin concentration, and the presence of ascites and cardiovascular disease remained significant independent predictors of survival. The results suggest that determination of the circulating level of noradrenaline and portal pressure may add to the prognostic information on survival obtained from routine tests. Thus, the activity of the sympathetic nervous system may indicate the severity of cirrhosis with respect to survival.

Abstract
Intraluminal pH was measured simultaneously in the human stomach and proximal duodenum with six small glass electrodes tied together at 1.5-cm intervals. Twenty-four healthy control subjects and 44 patients with duodenal ulcer disease were studied under fasting conditions and for 3 h after a standard liquid meal. Mean and median hydrogen ion activity, percentage of time with pH below 2 and 3, and the frequency of pH fluctuations were calculated from digital pH data sampled at a frequency of once per second from each electrode. None of these measurements of acidity differed significantly between the two groups or between subgroups of normosecretor controls and hypersecretor ulcer patients. At the time of pH study 15 of the patients had endoscopically verified active ulcer disease and 13 patients were without disease activity. Gastric as well as duodenal bulb acidity was the same in these two subgroups. We conclude that even though duodenal ulcer patients deliver more acid into the duodenum, this does not cause increased luminal acid aggression.

Abstract
The response to 5-aminosalicylic acid (5-ASA) in mild and moderately active Crohn's disease localized in the small bowel was studied in a randomized, double-blind, placebo-controlled trial in four centres. Sixty-seven patients were included, of whom 30 were treated with 1500 mg slow-release 5-ASA/day (Pentasa) for a scheduled period of 16 weeks. In the 5-ASA group 40% of the patients improved, versus 30% of the placebo-treated group ('intent to treat' basis; p greater than 0.1). Four of the patients treated with 5-ASA left the study owing to disease deterioration, versus 10 of the placebo-treated patients (p greater than 0.2). Seventeen patients were secondarily excluded, and the remaining 50 patients (23 receiving 5-ASA) were reevaluated in greater detail. No statistically significant differences in outcome were shown. Three patients (one given 5-ASA) were withdrawn from the study because of presumed side effects, but no serious adverse reactions were recorded. The present results indicate that 5-ASA, at least in the dosage used, is not superior to placebo. Nevertheless, trends towards a beneficial effect in Crohn's disease in the small bowel justify further clinical trials with a larger dosage of 5-ASA.

Abstract
One hundred and fifty-four patients with histologically verified non-alcoholic chronic liver disease were randomized to azathioprine or prednisone treatment. After a median of 91 months observation time, the cause of death was assessed retrospectively. Autopsy was performed in 82% of 71 deaths. In the azathioprine group 33% (13/39) died from malignant neoplasia, and in the prednisone group (13%) (4/32) (p = 0.08). Considering a possible fatal outcome as a consequence of treatment, this finding urges caution in the long-term application of azathioprine at the usual dose level.

Abstract
Sixty-seven patients with rheumatic disease, treated with non-steroidal anti-inflammatory drugs (NSAIDs), entered a controlled trial with a diagnosis of duodenal (n = 51), gastric (n = 14), or gastric and duodenal (n = 2) ulcers. The main objectives of the study were a comparison of ranitidine and sucralfate in ulcer treatment, and to observe the influence of continued NSAID administration during peptic ulcer therapy. Ulcers healed within nine weeks in 52 patients. The mean healing time was similar in 27 patients given ranitidine 150 mg bd (4.9 weeks) and 25 patients given sucralfate 1 g qid (4.6 weeks). In patients with unhealed ulcers after nine weeks of treatment, healing was obtained in seven after further therapy for 3-9 weeks. Of the 30 patients who continued NSAIDs during treatment with either ranitidine or sucralfate, 23 ulcers healed (mean healing time: 5.0 weeks). Of 32 patients in whom NSAIDs were stopped, ulcer healing was documented in 29 (mean healing time: 4.6 weeks). The difference in healing rates was not statistically significant (p greater than 0.10). The outcome of ulcer treatment did not differ in patients with rheumatoid arthritis and patients suffering from osteoarthritis. During a 12 month follow up 14 symptomatic ulcer recurrences were recorded.

Abstract
In situ pH was measured simultaneously with microelectrodes in the stomach, duodenal bulb, midduodenum, duodenojejunal junction, and proximal jejunum. Fourteen healthy subjects and 8 patients with exocrine pancreatic insufficiency were studied under fasting conditions and for 3 h after a standard liquid meal. The luminal pH gradient was steepest in the proximal 10 cm of the duodenum, where acidity was reduced from pH 2 to pH 5 in the fasting state and from pH 1.7 to pH 4.3 in the second and third postprandial hour. Acidity was further reduced in the distal duodenum to a pH between 5 and 6 at the duodenojejunal junction. The frequent wide and rapid pH fluctuations seen in the duodenal bulb were gradually reduced along the duodenum and became rare in the jejunum. In patients with pancreatic insufficiency, duodenal or jejunal acidity did not differ significantly from the controls, with the exception of the single 10-min period occurring 70-80 min after the meal when duodenal bulb pH was 2.1 as compared with 3.1 in the normal subjects (p less than 0.05). All patients, including 2 patients with a very high duodenal acidity, demonstrated a duodenal pH gradient as steep as that found in the normal subjects, indicating sources of bicarbonate other than the pancreas.

Abstract
The pharmacokinetics of 5-aminosalicylic acid (5-ASA) from sulphasalazine (SASP) and the slow-release 5-ASA preparation Pentasa was investigated in a cross-over study in 9 otherwise healthy patients with an ileo-rectal anastomosis. The 24-hour recoveries of the drugs were 90.5% and 84.7%, respectively. The median release of 5-ASA from SASP was 50% and from Pentasa 75%. Equal amounts of 5-ASA (18.0% vs 17.9%) were found in the faeces, and a significantly larger amount (4.4% vs 28.9%) of the metabolite N-acetyl-5-aminosalicylic acid (ac-5-ASA) was found in faeces following Pentasa. A larger amount of 5-ASA was absorbed and subsequently excreted in the urine, mainly as the metabolite (2.5% vs 20.5%) from Pentasa. This confirms previous results in ileostomized patients treated with Pentasa. The present findings also demonstrate that bacterial azo-reduction of SASP in patients with ileorectal anastomosis may be an adequate way to deliver 5-ASA in this type of patient. Both treatments may be used in these patients during a flare up of ulcerative colitis, but randomized studies are needed.

Abstract
In a randomized clinical trial in 148 patients of azathioprine vs. prednisone treatment of chronic aggressive hepatitis and/or nonalcoholic cirrhosis, 20 were HBsAg positive on entry. In this subgroup sequential serum samples were investigated for HBs and HBe markers by radioimmunoassay. At the time of evaluation, 13 patients were still alive; their median age was 53 years (25 to 72) and median follow-up time was 46 months (23 to 82). Of 16 patients with cirrhosis, 5 of 7 with persistence of HBeAg died, compared with 2 of 9 with anti-HBe. In three patients with anti-HBe, HBeAg reappeared several times with simultaneous rise in transaminase values. The overall survival was 65% after 5 years. The prognosis of HBsAg-positive chronic liver disease seemed to depend on the presence of cirrhosis and HBeAg rather than on improvement in biochemical activity during immunosuppressive treatment.

Abstract
A group of patients with non-alcoholic chronic liver disease from Copenhagen (148) and one from Naples (116) were investigated for the presence of viral and autoimmune serological variables by standardized methods. There were more hepatitis B virus (HBV)-induced cases among the Italians (38.8 versus 15.5%), but the sex ratio and biochemical activity were not different from the Danish ones. Autoimmune markers were much more frequent and in higher titers in Danish HBV-negative patients than in Italian ones. Fewer were women, and thus few Italians fit the theory of autoimmune pathology; rather, their chronic liver disease is caused by other hepatitis viruses than B.

Abstract
In order to evaluate the possible relation between hepatic function and hemodynamics and the increased humoral immune response of cirrhotic patients, titres of antinuclear antibodies (ANA) and smooth muscle antibodies (SMA) and concentrations of immunoglobulin (Ig) G, A and M were determined in 74 consecutive patients with alcoholic liver cirrhosis. Patients showed significantly (p less than 0.05) increased prevalences of ANA and SMA and concentrations of Ig G, A and M when compared to controls. No significant correlations were found between titres of ANA or SMA and hepatic scan score, galactose elimination capacity, indocyanine green clearance, hepatic blood flow and wedged-to-free hepatic vein pressure. Hepatic scan score correlated directly (rho = 0.38, p less than 0.05) to IgA concentrations; wedged-to-free hepatic vein pressure correlated directly to IgG concentrations (rho = 0.35, p less than 0.05) and to IgM concentrations (rho = 0.42, p less than 0.01). No other significant correlations were found between Ig concentrations and variables of hepatic function or hemodynamics.

Abstract
In a prospective study of the natural course of acute hepatitis, 157 of 1020 patients with biopsy-verified acute hepatitis could be classified as having hepatitis type non-A, non-B. We here report on the long-term prognosis for these 157 patients. The main type of exposure was drug addiction (40%), whereas 40% had no known hepatitis exposure. Only two patients had received blood products (blood transfusion and factor VIII). Follow-up liver biopsy (mean histological follow-up, 22 months) in 94 of the 157 patients showed chronic liver disease in 15-that is, cirrhosis in 6, suspicion of cirrhosis in 2, chronic aggressive hepatitis in 5, and chronic persistent hepatitis in 2. There was a striking predominance of elderly women with no known hepatitis exposure and with a high frequency of autoantibodies in serum among the patients with progression to chronicity, whereas chronic non-A, non-B hepatitis in drug addicts or after blood transfusions seems to be a limited problem. A comparison of histological features in the initial biopsies from patients with progression to chronicity or complete resolution showed piecemeal necrosis and abnormal bile duct epithelium to be of prognostic value.

Abstract
One hundred and forty-eight patients with non-alcoholic cirrhosis or chronic aggressive hepatitis entered a prospective, unblinded, randomized trial on the effect of azathioprine versus prednisone. For all 148 patients, there were no differences in survival related to the two drugs. In 99 patients the disease was classified as autoimmune, in 23 as posthepatitic, and in 26 as cryptogenic. No significant differences were seen in survival between these three groups of patients and no differences in survival related to the two drugs were registered within any of the groups. The autoimmune group included the patients with the biochemically most active disease, and a statistically significant reduction in activity was obtained with prednisone as well as azathioprine. Most remarkably, the frequencies of the autoantibodies were reduced parallel to the biochemical improvement in these patients. Immunosuppressive treatment was found to be rather ineffective in posthepatic chronic liver disease of type B; however, no signs of activation of the hepatitis B virus were seen.

Abstract
The mere presence of circulating immune complexes has been extensively reported in inflammatory liver diseases. In the present study, immune complexes were determined in 6 patients with HBsAg-negative chronic active hepatitis by sucrose density gradient ultracentrifugation. If present they were characterized concerning size and possible autoantibody-specificity. In four of these patients, zonal profiles differed markedly from normal controls and high molecular weight IgG-reactive substances with specificity against nuclear, smooth muscle and liver membrane antigens were demonstrated. Two patients were investigated repeatedly during one year of prednisone therapy and complex levels and size decreased along with clinical and biochemical improvement. Also in four positive controls with active SLE, complexes of up to 38 S containing antinuclear antibodies were detected. In contrast to patients with chronic hepatitis, SLE patients all had normal levels of serum gammaglobulin. It was concluded that immune complexes, present in liver disease without systemic organ-involvement and containing autoantibodies, might possibly reflect the normal immune clearance.

Abstract
Indirect immunofluorescence studies were performed using sera and IgG-Fab2 fragments from patients with chronic active hepatitis (CAH) who were positive for a liver membrane antibody (LMA). The specificity was investigated using hepatocytes from humans as well as rabbit, rat, guinea pig and monkey. Only sera also positive for smooth muscle antibody gave staining of lymphocytes and absorption with F-actin from rabbit muscle abolished this as well as all other smooth muscle staining without influencing LMA. It was concluded that LMA, routinely detected by indirect immunofluorescence using rabbit hepatocytes, represents specific binding to non-species-specific membrane antigens which are normal constituents of human hepatocytes. The antigen is separately located, and not cross-reactive with F-actin.

Abstract
The presence and persistence of IgM antibody against hepatitis B core antigen (anti-HBc IgM) and the correlation with other HBV markers were studied in 42 patients, all of whom had acute HBsAg-positive hepatitis but whose subsequent diseases differed. All patients initially had anti-HBc IgM. In 13 out of 15 patients with uncomplicated acute hepatitis, anti-HBc IgM disappeared within 6 months after onset of the disease. In five out of 12 patients, who in spite of transient HBsAg developed chronic liver disease, the anti-HBc IgM persisted for more than 2 years. Among 15 patients with persistent HBsAg, anti-HBc IgM was present from 7 months to more than 8 years. Seroconversion from HBeAg to anti-HBe was observed in seven patients and in five of these anti-HBc IgM disappeared during the follow-up period. These results indicate that anti-HBc IgM can be used as a serological marker of recent or ongoing HBV infection.

Abstract
The aim of this investigation was to elucidate a possible role of hepatitis B virus (HBV) in the pathogenesis of liver diseases in alcoholics. Two hundred and fifty-three alcoholics with liver disease were admitted to two medical departments in Copenhagen during a 15 months period. Seventy-nine patients (31%) showed serological signs (HBsAg, anti-HBs) of previous or active HBV infection. This is a significantly higher prevalence than found in an age-matched control population. Among the 79 patients with HBV markers, a total of 11 was found to be HBsAg-positive. From these 11 patients liver specimens were available for re-evaluation in nine cases. In only three of these liver biopsies, morphological changes indicating alcohol as the aetiological cause were found. In conclusion, different or concomitant aetiology must be considered in alcoholics with liver disease.

Abstract
Direct immunofluorescence studies were performed on isolated liver cells in order to detect surface localisation of IgG in acute and chronic hepatitis and primary biliary cirrhosis. Membrane-bound IgG was demonstrated in nine patients. Six of eight patients with primary biliary cirrhosis showed granular fluorescence on their liver cell surfaces suggesting that an antibody or immune complex-mediated cytotoxicity might be involved in the pathogenesis of this disease.

Abstract
Titres and immunoglobulin classes of autoantibodies were examined in 69 male patients with alcoholic liver cirrhosis and the findings were related to particular human leucocyte antigens and serum concentration of testosterone. Both anti-nuclear antibodies (ANA) and smooth muscle antibodies (SMA) were significantly more prevalent in patients with cirrhosis than in sex- and age-matched controls. Antimitochondrial antibodies and liver cell membrane antibody were found in 4% of the patients, and in none of the controls, but this difference was not significant. Patients with HLA-B8 and/or HLA-B12 had higher titres of ANA (n.s.) and SMA (P less than 0.05) than patients without these HLA antigens. Serum concentrations of testosterone were significantly lower in ANA-positive patients than in those negative (P less than 0.05), and a similar tendency was found in SMA-positive patients. With increasing titres of ANA the concentration of testosterone fell. Serum concentration of testosterone correlated inversely (P less than 0.05) with plasma immunoglobulin G and A. It is concluded that both genetic and hormonal factors may influence the humoral immune response in these patients.

Abstract
The prevalences of liver-cell-membrane antibody (LMA), smooth-muscle antibodies, antinuclear antibodies and antimitochondrial antibodies were evaluated in 63 selected patients with acute viral hepatitis of types A, B, and non-A non-B. Twenty patients had a complete, uneventful recovery, 19 patients had fulminant hepatitis, and 24 progressed to a chronic liver disease. Acute-phase and follow-up sera from all patients were tested for antibodies of IgA, IgM, and IgG class. The prevalences of the IgM autoantibodies in the acute-phase sera were not significantly different in the three groups irrespective of clinical outcome. Similar prevalences were found with respect to IgG class; however, antinuclear antibodies of IgG class were predominantly found in acute-phase sera from patients who later progressed to a chronic liver disease. The diagnostic significance of these autoantibodies was stressed by the fact that 85% of the sera with LMA of IgG class and 100% of the follow-up sera with smooth-muscle antibodies of IgG class at a titer at or above 1:128 originated from patients with chronic liver disease. A similar pattern was found for antinuclear antibodies, and testing for all these antibodies of IgA anad IgM class did not yield any further information. In some serum samples LMA could be found independently of smooth-muscle antibody and vice versa, indicating the essential difference between these two autoantibodies.

Abstract
Acute viral hepatitis B is considered to be an occupational risk to health-care workers worldwide. At the 1977 annual meeting of the Danish Society of Surgeons, 224 participants were examined for the presence of hepatitis B surface antigen (HGsAg) and antibody to HBsAg (anti-HBs) with use of a radioimmunoassay. None of the surgeons was HBsAg-positive, but 23% had anti-HBs. The prevalence of anti-HBs was five times higher among these surgeons than that in an age-matched control population. Hepatitis acquired during occupation as a surgeon was predominantly of type B, in contrast to hepatitis acquired before entering the surgical profession. Danish surgeons must be regarded as a group at high risk of hepatitis B infection.

Abstract
Eighteen consecutive patients with HBeAg in serum and histologically verified acute viral hepatitis were included in a follow-up study of the natural course of the disease. Five patients were followed up for from 2 to 6 months. Two of these healed clinically and cleared both HBeAg and HBsAg, while three were positive for HBeAg and HBsAg at the last control. Thirteen patients with a follow-up of from 27 to 102 months became HBeAg-negative during the time of observation. In all but one, progression of the liver disease stopped when HBeAg was cleared. The results further indicate a close association between the duration of HBe antigenemia and the severity of the liver disease.

Abstract
Sera from 70 patients with Sjogren's syndrome (SS), of whom 40 had primary and 30 secondary SS, were tested for various auto-antibodies of the IgG, IgA and IgM classes. 20% had liver-cell-membrane antibody (LMA), 90% had anti-nuclear antibodies (ANA), 40% salivary-gland antibodies (SGA), 13% anti-mitochondrial antibodies (AMA), 33% smooth-muscle cell antibodies (SMA), 9% skeletal-muscle antibodies (SKA) and only 1% had parietal-cell antibodies (PCA). In addition, 53% had IgM rheumatoid factor and 6 patients with anti-DNA antibodies all had SLE. 64% had increased serum IgG, 24% IgA and 14% IgM. A significantly higher incidence of ANA was found within all three Ig classes in patients with secondary SS. AMA and IgM-rheumatoid factor were also found to be elevated in this group. On the other hand, SGA occurred most frequently in patients with primary SS. LMA was mainly of the IgG class and IgG AMA and SMA were more often present in these patients than in those with a negative LMA reaction. The results of the investigation suggest inter alia that inflammatory liver disease, although not indicated by either the case history, physical examination or biochemical values, is probably present in patients with SS.

Abstract
Since type B hepatitis is generally regarded as an occupational risk for dentists, the participants at the 1976 annual meeting of the Danish Dental Association were examined for hepatitis B surface antigen (HBsAg) and antibody to HBsAg (anti-HBs). A total of 1,338 dentists (89% of the dentists at the meeting and 29% of all Danish dentists) were included in the study by completion of a questionnaire and by radioimmunoassay of a blood sample for HGsAg and anti-HBs. None of the dentists was HBsAg-positive, but 110 (8.2%) had anti-HBs. An increasing frequency of anti-HBs was found with increasing age, but the figures were similar to the findings in a control population. Evidence is presented that hepatitis found before admittance to or during the time at dental school was predominantly not of type B. In contrast, type B hepatitis predominated during the professional activity of the dentists. On the basis of the serological findings in 29% of all Danish dentists, it is concluded that dentists cannot be regarded as a high-risk group for hepatitis B.

Abstract
With an immunofluorescence technique using rabbit hepatocytes isolated by a non-enzymatic method an autoantibody directed against liver-cell-membrance was identified. Sera from 361 patients with various liver diseases and 274 patients with primary non-hepatic diseases-many associated with non-organ-specific auto-antibodies-were examined. The antibody (LMA) was found in 27 out of 72 patients with hepatitis-B-surgace antigen (HBsAg)-negative chronic active hepatitis and in 17 out of 28 patients with HBsAg-negative non-alcoholic cirrhosis. Only two patients had LMA and HBsAg, and both had chronic active hepatitis. One patient with extrhepatic disease was found to have LMA, and this patient had biochemical evidence of liver disease. Hence there is a close correlation between the presence of LMA and HBsAg-negative chronic inflammatory liver diseases and its detection may help in diagnosis.
