Abstract
BACKGROUND Most follow-up studies in patients with alcoholic liver cirrhosis have been for a 5-year period or less. The aim of this study was to assess the long-term mortality and causes of death among patients with alcoholic liver cirrhosis and to identify predictors of mortality. METHODS One hundred patients with alcoholic liver cirrhosis, consecutively admitted to one medical department, were included in the study from May 1984 until December 1988. All patients had a history of alcohol abuse of at least 100 g ethanol daily for several years. The study comprised 65 men and 35 women with a median age of 58 years (range 34-82). Percutaneous liver biopsies and/or autopsies were obtained on 89 patients. Sixty-seven had ascites at admission and 34% had bleeding oesophageal varices. All patients were followed prospectively until death or until October 2000. RESULTS During the follow-up period 90% of the patients died, 68 of whom (76 %) had been autopsied. The cumulative actuarial mortality after 1, 3, 6 and 12 months was 18%, 28%, 36% and 49%, respectively and after 5, 10 and 15 years 71%, 84% and 90%, respectively. None of the patients underwent liver transplantation during the study. The causes of death were bleeding, liver failure or a combination of these two conditions in 52 of 90 patients (58%), while 9 (11%) died of hepatocellular carcinoma 0.5 to 73 months after inclusion in the study. Using the Cox regression analysis, age, alcohol abuse and alkaline phosphatase were independent and significant predictors of mortality, but Child-Pugh class was not. CONCLUSIONS The mortality in a group of patients with advanced alcoholic cirrhosis was extremely high with 5 and 15 years' mortality in 71% and 90%, respectively. Independent predictors of a poor prognosis were high age, continuous alcohol consumption of more than 10 g ethanol per day and high levels of alkaline phosphatase.

Abstract
BACKGROUND The prevalence of hepatitis C (HCV) in Northern Europe has not been well described. This study aimed to estimate the prevalence and spectrum of hepatitis C infection in the general adult population of Oslo, Norway. METHODS The study was part of the Oslo Health Study 2000-2001 and included a random selection of individuals older than 30 years living in Oslo County. Sera from 11,456 participants were screened for anti-HCV (EIA-3), positive samples were confirmed (RIBA-3) and examined for HCV RNA (PCR). All anti-HCV positive patients were offered clinical evaluation. Routine biochemical liver tests were performed. Candidates for HCV treatment were asked to undergo a percutanous liver biopsy. RESULTS Among 11,456 participants HCV RNA was detected in 62 (0.5%) and HCV RNA with raised serum alanine aminotransferase (ALT) in 46 (0.4%). Anti-HCV was detected in 78 (0.7%) with a peak prevalence of 1.5% among subjects 40 and 45 years old. Being anti-HCV positive was associated with being unmarried, unemployed and having low education. Anti-HCV prevalence was higher among subjects with alcohol-related problems compared to those without (4.4% versus 0.6%, P < 0.001). It was also higher among smokers compared to non-smokers (2.0% versus 0.2%, P < 0.001). In 33 liver biopsies, bridging fibrosis was seen in 8 (24%) and cirrhosis in 1 (3%). The route of transmission was injecting drug use in 67%, transfusion in 6% and unknown in 27%. CONCLUSION In this population-based survey the prevalence of chronic hepatitis C was 0.5% and ALT was raised in 80% of those with chronic infection.

Abstract
BACKGROUND/AIM Previous studies have indicated that response to interferon therapy is inversely proportional to the amount of body iron stores. We have studied the relationship between serum ferritin, transferrin saturation, liver iron, presence of HFE-C282Y gene mutation and response to treatment in patients with chronic hepatitis C infection. METHODS Two hundred and fifty-six naive, HCV-RNA positive patients (60% males, median age 38 years, range 21-70) were treated with interferon and ribavirin for 6 months. Iron indices and the presence of the C282Y mutation were measured. In 242 (94%) patients iron deposition were determined by Perls staining method. Patients with negative HCV-RNA at 6 months after the end of treatment were defined as sustained viral responders. RESULTS Non-responders (n = 127) had significantly higher median s-ferritin values compared with sustained viral responders (130 microg/L vs. 75 microg/L P < 0.001). There was no difference in transferrin saturation among the two response groups. Only 23% (4/7) of patients with Perls grade 1 in liver biopsies responded to treatment vs. 54% (122/225) patients without iron deposition (P = 0.02), however, 10/13-non-responders had HCV genotype one. Two patients (0.8%) were homozygous for the C282Y mutation, 36 patients were heterozygous (14%). Among mutation carriers 26/38 achieved sustained response compared with 102/216 non-carriers (68% vs. 48%, P = 0.02). In a multivariate analysis s-ferritin (P = 0.030) and C282Y carrier status (P = 0.012) remained independent predict of sustained response. CONCLUSIONS Raised s-ferritin values predicate non-response to interferon-ribavirin therapy in hepatitis C patients. Response rate in C282Y mutation carriers seems greater than in non-carriers.

Abstract
BACKGROUND Interferon monotherapy for chronic hepatitis C virus (HCV) infection leads to sustained viral eradication in a minority of patients. However, in selected groups of patients, sustained virological response is observed in as many as 50% of patients. High initial interferon dose (induction therapy) has been reported to increase the initial response rate. We have studied the effect of interferon induction therapy in patients infected with HCV genotype 2b/3a, low viral load and no cirrhosis. METHODS A total of 71 treatment-naive HCV RNA-positive patients with biopsy-confirmed chronic hepatitis, with genotype 2b or 3a, viral load < or = 3 million copies per ml and no cirrhosis were randomized to receive either standard interferon therapy (3 MIU interferon-alpha-2a thrice weekly) for 26 weeks or 6 MIU interferon-alpha-2a daily for 4 weeks (induction group) followed by the standard dose (3 MIU thrice weekly) for 22 weeks. Those with persistent HCV RNA at 4 weeks stopped treatment. Patients were monitored for HCV RNA during and following treatment, and data were interpreted according to intention-to-treat analysis. RESULTS Viral clearance occurred more rapidly (after 4 weeks) in the induction group (33/36 = 92%) compared to the standard interferon group (21/35 = 60%) (P = 0.01). Among the initial responders, 23/33 (induction group) compared to 16/21 (standard group) were persistently HCV RNA-negative at the end of treatment. At 52 weeks (6 months' follow-up), 22/36 (61%) (induction group) compared to 10/35 (29%) (standard group) were HCV RNA-negative. Among initial responders, 22/33 (induction group) and 10/21 (standard group) achieved a sustained virological response. Among end-of-treatment responders, 22/24 (induction group) and 10/16 (standard group) were HCV RNA-negative at 6 months' follow-up (P = 0.013). CONCLUSIONS In patients infected with HCV genotype 2b/3a, low viral load and without cirrhosis, IFN induction therapy increases the initial viral clearance and reduces the risk of relapse in end-of-treatment responders. A sustained virological response was achieved in 61% of the patients receiving IFN induction therapy.

Abstract
BACKGROUND The efficacy of interferon-alpha (IFN) induction in combination with ribavirin for chronic hepatitis C virus (HCV) infection is not known. METHODS A total of 256 treatment-naive HCV RNA-positive patients with biopsy-confirmed chronic hepatitis were enrolled in a randomized multicentre study. The patients received either standard combination therapy with 3 MIU interferon-alpha2b thrice weekly for 26 weeks or 6 MIU interferon-alpha2b daily for 4 weeks and 3 MIU 3/7 days for 22 weeks. All patients received ribavirin 1000 mg or 1200 mg (weight dependent) daily during the 26-week treatment period. Patients were monitored for HCV RNA during and following treatment. RESULTS The sustained virological response rates (26 weeks after end of treatment) were 54% and 47% for patients receiving IFN induction/ribavirin and standard IFN/ribavirin, respectively (P = 0.35). Among patients infected with genotype 1a/1b, the sustained response rates were 32% and 35%. In patients infected with genotype 2b/3a IFN induction/ribavirin led to a sustained response rate of 80% as compared to 65% in the standard combination therapy group (P = 0.073). Steatosis was more frequently seen in liver biopsies from patients infected with genotype 3a as compared to genotypes la/lb. Among genotype 1a/1b infected patients. steatosis was a highly significant predictor of failure to achieve sustained virological response. Logistic regression analysis (multivariate analysis) showed that independent predictors of sustained virological response were low age, female gender, genotype 2b/3a and HCV RNA negativity at 2 weeks. CONCLUSIONS IFN induction in combination with ribavirin does not increase the sustained virological response rate among patients infected with HCV. Absence of steatosis is an independent predictor of sustained virological response in patients infected with genotypes 1a/1b.

Abstract
BACKGROUND There is a growing interest in nonalcoholic steatohepatitis (NASH), a disease entity which is quite similar to alcoholic liver disease. MATERIAL AND METHODS We present three patients with nonalcoholic steatohepatitis, and review current opinion on this disease entity. RESULTS Non-alcoholic steatohepatitis is very often associated with the insulin resistance syndrome. There is also an association with hepatic iron overload. In one of our patients, biochemical improvement occurred after treatment with phlebotomy. Insulin resistance, resulting in fat accumulation, seems to be an important first step in the pathogenesis. Free fatty acids, iron, and other sources of oxidative stress probably result in cell damage. In some patients, these events result in necroinflammation mediated by various cytokines and immunoactive cells. The prognosis in pure steatosis is usually good. Presence of necroinflammation or fibrosis indicates a risk of progressive liver disease, including cirrhosis.

Abstract
BACKGROUND The prevalence of hereditary hemochromatosis in Norway is one of the highest reported in the world. However, the clinical presentation in patients with hemochromatosis in Norway seems to be different compared with recent studies elsewhere. The aim of this study was to investigate patients with hemochromatosis in one community hospital in Norway and to study the prevalence of the C282Y mutation. METHODS One hundred and twenty patients were consecutively admitted to one medical department in Oslo. Serum transferrin and ferritin concentrations were measured in all patients, and a percutaneous liver biopsy was obtained in 108 of 120 (90%) patients. Stainable iron (Perls stain) in hepatocytes was graded from 0 to 4+ and fibrosis from 1 to 4. Genotyping for the C282Y and H63D mutation in the HFE gene was performed by PCR-RFLP. RESULTS Forty-eight (40%) of the patients suffered from tiredness and astenia and 29 (24%) had typical arthropathy. Only 5 of 105 (4.5%) had biopsy confirmed cirrhosis and 5 had diabetes mellitus. Patients referred from a blood bank had significantly less symptoms and signs compared with other patients. Twenty-one of 120 (17.5%) patients were C282Y mutation negative. Seventeen (81%) of these patients (16 women and 1 man) had a history of extensive oral iron intake lasting from 5 to 50 years. When excluding those with extensive oral iron intake (n = 17), 92 of 103 (89%) were homozygous for the C282Y mutation, 7 (7%) were heterozygous including 3 compound heterozygous and 4 (4%) were mutation negative. CONCLUSIONS Only a minority of our patients with hemochromatosis had a far advanced disease at the time of diagnosis (less than 5% had cirrhosis) and hemochromatosis in a majority of the C282Y mutation negative patients was associated with excessive oral iron intake for several years.

Abstract
BACKGROUND Hepatotoxic reactions associated with carbamazepine therapy are well recognised, and it is important that clinicians are aware of this adverse effect. MATERIAL AND METHODS We present the clinical course in three patients with carbamazepine-induced hepatitis. RESULTS All three patients had clinical and biochemical signs of hepatitis; improvement occurred immediately after carbamazepine therapy was discontinued. Other causes of hepatitis were excluded. INTERPRETATION Previous reports concerning this adverse effect are reviewed. Focusing on the liver as the major organ for drug metabolism, we discuss possible pathophysiological mechanisms of drug-induced hepatic injury. A thorough medication history is mandatory in all patients with hepatitis and other liver diseases. The prognosis of carbamazepine-induced hepatitis is usually excellent, but fatal cases have been reported.

Abstract
BACKGROUND Preliminary results from combination therapy with interferon-alpha and ribavirin (IFN/Rib) in patients with chronic hepatitis C have been promising, with up to 50% sustained hepatitis C virus (HCV) RNA response. The aim of this study was to investigate whether a sustained HCV RNA response could be obtained with combination therapy in patients who were non-responders or relapsers after IFN treatment. METHODS In a multicenter study we randomized 53 HCV RNA-positive patients into 2 treatment groups. They all had biopsy-confirmed chronic hepatitis C, and all were recruited from a previous IFN study: 26 were previous non-responders and 27 responders with relapse. Group A received interferon-alpha2a, 4.5 MIU thrice weekly for 6 months, and group B received ribavirin, 1000-1200 mg/day, in combination with the same dose of interferon-alpha2a for 6 months. Median Knodell index was 5.0 in both groups. Genotype 1 was found in 24 (45%), type 2 in 3 (6%), and type 3 in 26 (49%). RESULTS Sustained clearance of HCV viremia 6 months after interferon-alpha2a treatment stop was obtained in 12 of 53 patients (23%): 6 of 27 in the IFN group (22%) and 6 of 26 (23%) in the IFN/Rib group (NS). Nine of 27 (33%) former responders with relapse, compared with 3 of 26 (12%) non-responders, obtained a sustained HCV RNA response (P = 0.054). In previous relapse patients sustained loss of viremia was more frequent in genotype 3 (50%) than in genotype 1 (11%) patients (P = 0.022). CONCLUSIONS In a group of previous IFN-alpha2a-treated chronic HCV patients we obtained a similar sustained clearance of viremia when retreated either with IFN-alpha2a alone or with a combination of IFN-alpha2a and ribavirin for 6 months. Previous relapse patients with HCV genotype 3 obtained sustained loss of viremia significantly more often (50%) than type-patients (11%). Previous IFN responders with relapse responded better than previous non-responders.

Abstract
PURPOSE The study contained herein was undertaken to investigate fecal calprotectin excretion in a series of patients with colorectal carcinoma and to determine whether the excretion was influenced by localization or stage of the tumor. Furthermore, the effect of surgical treatment on the concentrations was studied. Fecal calprotectin was also compared with plasma concentrations of calprotectin, carcinoembryonic antigen, and C-reactive protein. METHODS Fecal calprotectin was measured in 119 consecutive patients admitted for treatment of colorectal carcinoma. In 116 (97.5 percent) patients, resectional surgery was performed. Plasma calprotectin was measured in 90 (76 percent) patients, carcinoembryonic antigen in 88 (74 percent) patients, and C-reactive protein in 82 (69 percent) patients. RESULTS Median fecal calprotectin concentration in the 119 patients was 50 (range, 2-950) mg/l, which was significantly (P < 0.0001) higher than in 125 control patients (median, 5.2 mg/l). In 23 patients studied also after resection, the excretion fell greatly. There were no significant differences in fecal calprotectin concentration among patients with different tumor stages. Elevated plasma calprotectin concentrations were found in 67 of 90 (73.3 percent) patients with colorectal carcinoma, compared with elevated fecal calprotectin in 111 of 119 (93.3 percent) patients, and there was no significant correlation between plasma and fecal calprotectin concentrations. Plasma calprotectin concentrations were significantly lower in patients with T1 or T2 tumors than in those with more advanced stages (P = 0.0025). CONCLUSION Measurement of fecal calprotectin may become a diagnostic tool in detecting colorectal carcinoma. The specificity in relation to colorectal carcinoma has not, however, been completely investigated. Both neoplastic and inflammatory conditions may be associated with elevated values; therefore, it is unlikely that calprotectin can predict specific colonic disorders.

Abstract
BACKGROUND Hepatitis G virus (HGV) or GBV-C is frequently detected in patients co-infected with hepatitis C virus (HCV). This study investigated host and virologic factors influencing the response to HGV/GBV-C to alpha-interferon treatment. METHODS HGV/GBV-C was detected and quantified by nested polymerase chain reaction. The influence of variables such as liver biopsy appearance, liver function abnormalities, and response of HCV to interferon treatment was monitored. RESULTS Fourteen of the 25 HGV/GBV-C-infected patients treated with interferon (3-6 MIU three times a week for 6 months) became non-viraemic during treatment, although all relapsed after treatment withdrawal at 6 months, with no net change in virus load between 0 and 12 months. CONCLUSIONS Predictive factors for clearance of HGV/GBV-C viraemia by interferon were pre-treatment severity of liver disease (median Knodell score of 4, compared with 7 for non-responders; P = 0.030) and alanine aminotransferase levels (median, 114, 182 for non-responders; P = 0.039). Clearance was associated with the treatment response of HCV. Nine of 13 who cleared HGV/GBV-C also cleared HCV, compared with 3 of 11 HGV/GBV-C non-responders; P = 0.05). The shared susceptibility of HGV/GBV-C and HCV to interferon treatment suggests a link between the mechanism of clearance of the two viruses.

Abstract
BACKGROUND The relative frequencies of the autoimmune liver diseases primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC), and autoimmune hepatitis (AIH) have not been studied. We therefore performed an epidemiologic investigation to describe the incidence and prevalence of the three diseases in a defined population. METHODS Patients with PBC, PSC, or AIH admitted to Aker University Hospital in Oslo were prospectively registered during the 10-year period 1986-95. This hospital serves a defined population of 130,000 inhabitants. The mean yearly incidence and the point prevalences at the end of each year were calculated. RESULTS During the 10-year period 21 patients with PBC, 17 with PSC, and 25 with AIH were diagnosed. The mean annual incidence per 100,000 was 1.6 for PBC, 1.3 for PSC, and 1.9 for AIH. The point prevalences per 100,000 on 31 December 1995 were 14.6, 8.5, and 16.9 for PBC, PSC, and AIH, respectively. CONCLUSIONS The prevalences of PBC and AIH are of the same order of magnitude and about twice as high as that of PSC. These epidemiologic data can be used to estimate the number of liver transplantations required due to autoimmune liver diseases.

Abstract
Patients with ulcerative colitis in our catchment area were followed over a ten-years period with the focus on the relation between the extent of inflammation and complications. Total colitis was found in 180 out of 334 patients with known extension, while in 154 of the patients the inflammation was classified as left-sided colitis. The frequency of severe colitis, colectomy and cancer was more or less the same as stated in earlier reports. We observed a difference, however, between the patients with extensive colitis and those with left-sided colitis as regards the course of the disease and the complications related to ulcerative colitis. The risk of liver disease, severe colitis and colectomy were significantly higher among the patients suffering from extensive colitis. Extraintestinal manifestations, on the other hand, were equally distributed among both groups of patients. The reasons for the observed differences are unknown.

Abstract
BACKGROUND/AIMS The observed prevalence of hemochromatosis has ranged considerably from 0.05 to 0.37% in studies requiring liver biopsy. We aimed to study the prevalence of genetic hemochromatosis among Norwegian blood donors. METHODS We studied 10,552 healthy blood donors (5312 women and 5240 men) using serum ferritin as a screening parameter. If serum ferritin concentration was > or = 100 micrograms/l in women and > or = 200 micrograms/l in men, serum iron and transferrin (measured as total iron binding capacity = TIBC) were measured. Blood donors who repeatedly had a transferrin saturation above 40% and a ferritin concentration above these limits were referred to a hepatologist (H.B.). RESULTS Serum ferritin was > or = 100 micrograms/l in 94/5312 (1.8%) women and > or = 200 microliters in 79/5240 (1.5%) men. Of these, 37 persons had a serum ferritin concentration above 100 micrograms/l (females) or above 200 micrograms/l (males) and a transferrin saturation above 40%. Nineteen of them (13 men and 6 women, median age 36 years, range 28-68) were identified as having hemochromatosis on the basis of increased hepatic iron index. Serum ferritin ranged from 111 to 1980 micrograms/l (median 357 micrograms/l and transferrin saturation from 50 to 100% (median 92%), hepatic iron from 48 to 471 mumol/g dry weight (median 118 mumol/g) and hepatic iron index from 1.5 to 12.1 (median 3.0). One person had cirrhosis and none had diabetes. The prevalence of hemochromatosis was significantly higher among first-time blood donors (12 out of 3500 [3.4/1000]) compared with repeat donors (7 out of 7052 [1/1000]), p < 0.005. CONCLUSIONS The observed prevalence of hemochromatosis in Norwegian first-time blood donors of 0.34% is comparable to recently observed prevalences in other studies. However, the use of serum ferritin as a first-step screening tool may have failed to detect hemochromatosis in the early stage where iron overload has not yet occurred.

Abstract
This study comprised 62 outpatients with ulcerative colitis who underwent 64 colonoscopies. The disease activity was evaluated according to endoscopic and histological criteria. The results revealed a significant correlation between both the endoscopic as well as the histological gradings of disease activity and faecal calprotectin. The median faecal calprotectin levels in the control group (6 mg/l) and in the patients with no or low disease activity (11.5 mg/l) were significantly different (p < 0.0001). The median calprotectin level among patients with active disease was 68 mg/l which was significantly different from the latter group (p < 0.0001). Furthermore, we suggest that the degree of inflammation rather than the extent of the disease determined the faecal calprotectin levels. In conclusion, assessment of faecal calprotectin seems to be a marker of disease activity in patients with ulcerative colitis.

Abstract
Patients with chronic hepatitis C respond differently when treated with interferon. We randomized 116 patients with chronic hepatitis C in order to compare two dosage regimens of recombinant interferon alpha 2a:3 MIU x 3 per week for 6 months (arm A) or 6 MIU x 3 per week for 3 months and then 3 MIU x 3 per week for 3 months (arm B). There were no significant differences concerning outcome between the two dose regimens: sustained clearance of HCV viremia 6 months after the end of treatment was obtained in 12/59 (20%) in group A compared with 18/57 (32%) in group B (p = 0.24). In patients with genotype 1a, 4/31 (13%), in genotype 1b, none of 9 (0%), 9/15 (60%) in genotype 2, and 17/58 (29%) in genotype 3, showed sustained clearance of HCV viremia 6 months after the end of treatment (p = 0.002). In a stepwise logistic regression analysis, only pretreatment viral load (p = 0.0001), genotype (p = 0.001) and age (p = 0.04) were identified as independent predictors of sustained clearance of HCV viremia. Liver histology as assessed by Knodell index was significantly improved in patients with sustained HCV RNA response 6 months after the end of treatment (5.2 +/- 2.2 vs 2.6 +/- 2.2, p < 0.001), but not in responders with relapse or in non-responders. In conclusion, stepwise logistic regression analysis showed that viral load, HCV genotype and age were the only independent predictors for sustained HCV RNA response.

Abstract
Among 116 patients with biopsy-confirmed chronic hepatitis C (Riba 2 or Riba 3 positive) in a multicenter study in southern Norway on interferon, we determined hepatitis C virus genotype by restriction fragment length polymorphism (RFLP) of the 5' NCR. The RFLP method was supplemented by and compared with a serological typing method based on the detection of type-specific antibody to peptide from the NS-4 region. A total of 102/106 (96%) patient sera showed detectable type-specific antibody to NS-4 peptides and corresponded in all cases, except two, to the genotype detected by polymerase chain reaction. Combining the results from RFLP genotyping and serotyping, genotype 1 was found in 40 (35%) (27 with 1a and 10 with 1b, 3 subtypes not determined), genotype 2 in 15 (13%) (subtype 2b in 14 and 1 subtype not determined), and genotype 3 in 58 (50%) of patients. The low mean age of the patients (34 years), the low prevalence of cirrhosis (3.5%), the short duration of the disease, and a high prevalence of intravenous-drug abusers may account for the low prevalence of infection with genotype 1b (9%). The epidemiological features of hepatitis C patients are markedly different from patient groups described in southern Europe in terms of risk factors, age, and genotype distribution.

Abstract
We investigated a group of 111 amenorrhoeic females with associated liver disease. These comprised alcoholic cirrhotics (N = 38), non-alcoholic cirrhotics (N = 12), non-cirrhotic alcoholics (N = 21) and those suffering from other chronic liver diseases (N = 40) admitted to our medical department from 1986 to 1991. The serum levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), oestradiol, testosterone, sex hormone binding globulin (SHBG) and prolactin were measured. Serum LH was decreased below the normal range in 50% of patients with alcoholic cirrhosis and in 42% of patients with non-alcoholic cirrhosis. One third of non-cirrhotic alcoholics also had decreased LH, in contrast to only 8% of patients with other chronic liver diseases (p < 0.01). A close correlation was found between LH and FSH when all patients were pooled (r = 0.91, p < 0.001). A gonadotrophin-releasing hormone (GnRH) injection elicited a clear LH and FSH response in 11 out of 14 patients with cirrhosis, indicating that the hypothalamus rather than the pituitary is the site of disturbance in gonadotrophin secretion. Serum SHBG was within normal limits and similar in all four groups. In nine females with alcoholic cirrhosis who abstained for 3 months, serum SHBG increased significantly from 39 +/- 18 to 70 +/- 25 nmol/l (p < 0.001), while LH increased in five of nine females and was unchanged in four. In conclusion, half of the amenorrhoeic females with alcoholic as well as non-alcoholic cirrhosis had inappropriately low serum LH and FSH levels, indicating dysfunction of the hypothalamo-pituitary axis.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
BACKGROUND Topical treatment is effective in patients with distal ulcerative colitis. This trial compares the efficacy, safety, and practicality of 4 weeks' treatment with 500 mg mesalazine suppositories with those of 178 mg hydrocortisone foam, both given twice daily. METHODS Seventy-nine patients with distal ulcerative colitis were stratified on the basis of the extent of the disease (proctitis and proctosigmoiditis) and randomized to one of the treatment groups. A disease activity index (DAI) based on symptoms and endoscopic findings was calculated. The patients evaluated the practicality of the treatment regimens, patients compliance was measured, and histologic findings recorded. RESULTS Of all the patients 22% and 38% were complete responders after 2 and 4 weeks, respectively. Median DAIs in the mesalazine and hydrocortisone groups before and after 2 and 4 weeks' treatment were 14, 6, and 4, and 13, 8, and 6, respectively. The difference between the treatment groups was statistically significant (p = 0.02) due to a better effect of mesalazine in patients with proctitis. Patients' evaluation of practicality and patient compliance were statistically significantly better in the mesalazine group. CONCLUSIONS Both treatment regimens are effective; mesalazine suppositories seem to be the preferred alternative.

Abstract
OBJECTIVES To compare serum ferritin concentration and transferrin saturation in patients with alcoholic and non-alcoholic chronic liver diseases. DESIGN Consecutive patients with liver diseases. SETTING The department of internal medicine in a teaching hospital. SUBJECTS Three hundred and twelve patients with different liver diseases consecutively admitted between 1987 and 1992. INTERVENTIONS None. MAIN OUTCOME MEASURES Fasting serum iron, transferrin and ferritin. RESULTS Serum ferritin was increased above 200 micrograms L-1 in all 18 patients with haemochromatosis (range 310-6500 micrograms L-1), in 64 of 111 alcoholics (58%) and in 30 of 137 (22%) with chronic non-alcoholic liver diseases (P < 0.01). Twelve of 111 alcoholics (11%) had serum ferritin above 1000 micrograms L-1 compared with one of 137 (0.7%) with chronic non-alcoholic liver diseases. In 13 alcoholics who abstained after admission, serum ferritin decreased from 1483 micrograms L1 +/- 1134 to 388 micrograms L-1 +/- 237 (P < 0.001) after 1 1/2 to 6 weeks. The transferrin saturation was increased above 62% in 13 of 18 patients (72%) with haemochromatosis, in 16 of 105 alcoholics (15.2%) and in three of 132 (2.3%) with chronic non-alcoholic liver disease (P < 0.01). CONCLUSION Serum ferritin is more frequently elevated in abusing patients with alcoholic liver disease than in patients with other chronic liver diseases such as autoimmune liver diseases and hepatitis C. Because serum ferritin decreases rapidly during abstinence, the measurement of ferritin for the detection of haemochromatosis in patients abusing alcohol should be postponed until the patients are abstaining. Most of the patients with increased serum ferritin have normal transferrin saturation values which can be used to separate them from haemochromatosis.

Abstract
During the period 1986-93 22 patients were diagnosed as having primary hemochromatosis. Only 11 of them had elevated aminotransferases. Transferrin saturation was higher > 63% in 17 (77%) and serum-ferritin was higher in all the patients. (257 mumol/l to 6,500 mumol/l). A percutaneous liver biopsy was performed in 20 patients, all of whom showed a characteristic grading from 2 + to 4+ using Perls' stain. Two males had cirrhosis with simultaneous hepatocellular carcinoma, and another two had cirrhosis. One patient had diabetes mellitus type I. We conclude that fasting serum-iron and transferrin should be determined in all subjects over 40 years of age and in patients with chronic elevation of liver enzymes. If transferrin saturation is higher than 50% in females and 60% in males, serum ferritin should be determined. A percutaneous liver biopsy should be performed if both values are higher than normal. Screening of siblings is important because of the autosomal recessive pattern of inheritance.

Abstract
Computed tomography (CT) was performed to estimate the density of the hepatic and splenic parenchyma in 18 patients with hemochromatosis. The mean CT density was 79 +/- 21 Hounsfield units compared with 61 +/- 9 (p < 0.01) in 31 controls without hepatic disease. Increased density above 79 Hounsfield units was found in eight patients out of 18 (44%). The highest density (125 Hounsfield units) was found in a patient with a serum ferritin of 6500 micrograms/l. There was an association between CT density and serum ferritin (r = 0.72, p < 0.01). The difference in density between liver and spleen gave better discrimination between patients and controls: 12 of 18 (67%) showed an increased difference in density between liver and spleen. We conclude that CT represents a non-invasive alternative to liver biopsy in cases where the latter is contraindicated. However, CT is not sensitive when serum ferritin is below 1,000 micrograms/l.

Abstract
During the period from 1985 to 1993 primary sclerosing cholangitis was diagnosed in 16 patients, five females and 11 males, mean age 43 years. 12 of the patients (75%) had inflammatory bowel disease. Among 262 patients with ulcerative colitis, cholangitis was found in ten, whereas the disease was diagnosed in only two (1.9%) of the 108 patients with Crohn's disease. In eight patients (50%) no progression of the cholangitis was observed. However, six patients (38%) died during the observation period, three 19% due to cholangiocarcinoma and one due to liver failure. Cholangiocarcinoma is frequently found in patients with primary sclerosing cholangitis. A mortality of 38% indicates a serious clinical course in many patients.

Abstract
We measured serum levels of carbohydrate deficient transferrin (CDT) in 420 subjects: 100 healthy blood donors, 82 healthy employees, 70 abstaining patients with different chronic nonalcoholic liver disease, 16 abstaining patients with alcoholic fatty liver, 50 abstaining patients with alcoholic liver cirrhosis, 25 abusing patients with alcoholic fatty liver, 41 abusing patients with alcoholic liver cirrhosis, and 36 patients with alcohol dependence syndrome with a daily ethanol consumption of 173 +/- 120 g the last 4 weeks before blood was drawn. In controls the serum level of CDT was significantly higher in females compared with males (17.7 +/- 5.1 and 13.7 +/- 3.8 units/liter, respectively), and the upper normal limit was defined as 27 and 20 units/liter. Sixty-two of 102 (60.8%) abusing patients with alcoholic liver disease had increased levels of CDT compared with 1 of 66 abstaining (1.5%) patients with alcoholic liver disease, and 10 of 70 (14.3%) abstaining patients with nonalcoholic liver disease among them 3 with primary biliary cirrhosis and 2 with chronic autoimmune hepatitis. No correlation was found between serum CDT and gamma-glutamyltranspeptidase (GGT), AST, ALT, and mean red cell volume (MCV). The sensitivity and specificity for serum CDT was 61 and 92%, respectively, compared with 85 and 18% for GGT and 70 and 66% for MCV. No advantage was gained by using the CDT/transferrin ratio. Our study confirms that CDT is a specific marker for chronic alcohol abuse, except in few patients with other chronic liver diseases. Serum CDT seems to be a better indicator of abstention than GGT; AST and MCV in patients with alcoholic liver disease. However, in our hands CDT is not so sensitive for alcohol abuse in patients with liver disease as reported earlier in unselected alcoholics.

Abstract
We studied 50 patients (36 males and 14 females) with chronic hepatitis C who were admitted consecutively to our medical department during the period 1987-91. Eight patients (16%) had had a blood transfusion, 17 (34%) had used intravenous drugs and 25 (50%) were "sporadic cases" with no identifiable risk factor except that at least five had been tattooed. Most of the patients had moderate symptoms, including tiredness and asthenia. Few were jaundiced. A percutaneous liver biopsy was performed in 27 patients and showed chronic persistent hepatitis in 12 of them, chronic active hepatitis in six and cirrhosis in nine. Three patients with cirrhosis died; one from hepatoma, one from an endstage cirrhosis with bleeding and coma hepaticum, and one from septicaemia.

Abstract
The coagulation inhibitor protein C was measured in 151 patients with various liver diseases. The protein C level was significantly decreased in patients with alcoholic cirrhosis (n = 73) compared to patients with steatosis (n = 24) (40 +/- 2%) vs. 88 +/- 4%, mean S.E., p less than 0.001). It was also decreased in cases of acute liver damage (n = 8) and in patients with non-alcoholic cirrhosis (n = 15) (35 +/- 7% and 36 +/- 4%, respectively). A significant correlation was found between protein C and Normotest, antithrombin, heparin cofactor II, (r = 0.83, r = 0.82, r = 0.81, respectively, p less than 0.001). There was also a significant correlation between protein C and serum concentrations of albumin (r = 0.61, p less than 0.001), but a negative association to bilirubin (r = -0.56). No significant association was found between protein C and aspartate aminotransferase, alaline aminotransferase, and gamma-glutamyltranspeptidase. In conclusion, protein C is low in advanced liver diseases and gives the same amount and type of information as Normotest, antithrombin and heparin cofactor II.

Abstract
The concentration of alpha-tocopherol was measured in liver biopsy specimens obtained from 83 patients with alcoholic and non-alcoholic liver diseases. The mean hepatic vitamin E content (as alpha-tocopherol) was significantly lower in 23 patients with alcoholic cirrhosis (17.6 +/- 12.1 nmol/mg wet weight liver), compared with 12 patients with normal liver histology (39.2 +/- 29.7 nmol/mg, P less than 0.01). The mean serum concentration of alpha-tocopherol was lower in patients with alcoholic cirrhosis (13.9 +/- 7.0 mumol/l) than in individuals with alcoholic fatty liver (21.3 +/- 9.3 mumol/l, P less than 0.01) and patients with normal liver histology (23.4 +/- 11.6 mumol/l, P less than 0.01). A decreased ratio of serum alpha-tocopherol/total serum lipids was also observed in patients with alcoholic cirrhosis, compared with patients with normal liver histology (P less than 0.05). There was a significant correlation between concentrations of alpha-tocopherol in liver and serum (r = 0.43, P less than 0.001). Furthermore, serum alpha-tocopherol correlated with retinol (r = 0.53, P less than 0.001), selenium (r = 0.45, P less than 0.001), and albumin (r = 0.37, P less than 0.001) in serum. We suggest that the reduced content of hepatic alpha-tocopherol observed in some patients may play a role in ethanol-induced lipid peroxidation.

Abstract
A 49 year old female was started on disulfiram. Six weeks later she was given naproxen because of epicondylitis. After 5 days' treatment with naproxen she complained of nausea, anorexia and jaundice. At admission, bilirubin was 452 mumol/l, aspartate aminotransferase (ASAT) 1925 U/I, alanine aminotransferase (ALAT) 2815 U/I and prothrombin time measured as Normotest was 27%. The patient developed a fulminant hepatitis and died in hepatic coma almost four weeks after the introduction of naproxen. Postmortem examination disclosed a small liver (1,100 g) and histological examination showed massive necrosis and collapse of the lobules. The naproxen was the most probable cause of death, but it is impossible to exclude disulfiram as causative agent.

Abstract
The connection between alcoholic liver disease and hypogonadism has long been recognized. In this study of 112 males admitted to a medical department, altogether 87 had alcoholic liver disease. Serum testosterone was depressed (less than 12 nmol/l) in 47 out of 51 (92%) patients with alcoholic liver cirrhosis and in 13 out of 36 (36%) with alcoholic fatty liver (p less than 0.001). Primary hypogonadism was found in 8% of the patients with alcoholic fatty liver and in 16% of the patients with alcoholic cirrhosis and secondary hypogonadism in 28% of the patients with fatty liver and in 76% of those with alcoholic cirrhosis. Serum sex hormone binding globulin (SHBG) was increased (greater than 40 nmol/l) in 65% of the patients with fatty liver and in 67% of the patients with alcoholic cirrhosis. Serum testosterone was significantly correlated to liver function tests Normotest (NT), bilirubin and albumin. In conclusion, hypogonadism is very common in men with alcoholic liver disease.

Abstract
Increased levels of serum procollagen III peptide (P-III-P) have been found in patients with alcoholic hepatitis and cirrhosis. Serum P-III-P was increased (greater than 15 micrograms/l) in 38 of 44 (86%) patients with alcoholic liver cirrhosis, in 6 of 20 (30%) with fatty liver, in 1 of 13 (8%) with non-alcoholic fatty liver, and in 3 of 14 (21%) with other chronic liver diseases. Median serum P-III-P was almost three times higher in alcoholic liver cirrhosis than in alcoholic fatty liver (p less than 0.001). Serum P-III-P was increased in three of six patients with alcoholic fatty liver and periportal fibrosis. In the total material (n = 91), a statistically significant negative correlation between serum P-III-P and albumin (r = -0.71, p less than 0.001) and Normotest (r = -0.63, p less than 0.001), respectively, and a positive correlation between serum P-III-P and bilirubin (r = 0.65, p less than 0.001) were found. The serum level of P-III-P had no prognostic value concerning the mortality in patients with alcoholic cirrhosis.

Abstract
Liver retinoid levels and the retinyl esters were examined in liver biopsy specimens from 70 patients with alcoholic and nonalcoholic liver diseases. There was a wide variation in the liver retinoid levels. The liver retinoid level was statistically significantly lower in 15 patients with alcoholic liver disease and a depressed Normotest (NT) value of less than 65% compared with patients with alcoholic liver disease and a normal NT value of greater than 65% (P less than 0.01). The mean serum retinol level in patients with alcoholic cirrhosis was 0.68 +/- 0.38 mumol/l compared with 1.99 +/- 1.14 mumol/l in patients with alcoholic fatty liver (P less than 0.03). The relative amount of retinyl oleate was increased in the alcoholic fatty liver compared with the nonalcoholic fatty liver (P less than 0.001).

Abstract
A patient with congenital primary hypothyroidism is presented. His thyroid gland had a normal uptake of radioiodine which was independent of endogenous or exogenous TSH, sympathetic B-receptor blockade or prostaglandin inhibition. Infusion of dibuturyl-cyclic AMP increased the uptake of radioiodine and stimulated release of protein bound 131I. He had no goitre even when he did not receive thyroxine, but thyroid histology showed evidence of active epithelium in the presence of adequate substitution with thyroxine. We assume that some unknown factor other than TSH stimulates part of the glandular function in this patient, without leading to adequate formation and release of thyroid hormone.

Abstract
The distribution and excretion of mercury were studied in mice given a single injection of HgCl2 with or without chelation treatment. DMS (2,3-dimercaptosuccinic acid) given intravenously (0.5 mmol SH/kg) to mice 24 h after the mercury injection reduced the kidney Hg level significantly, while NAPA (N-acetyl-DL-penicillamine) and BAL (2,3-dimercaptopropanol) did not. The effectivity of DMS to remove Hg from kidneys was comparable to that of BAL-sulph (2,3-dimercaptopropane-1-sulfonate), irrespective of whether these chelating agents were given orally or intravenously. Immediate chelation treatment with DMS or mercaptodextran reduced the renal Hg level to about 50% of control levels, as measured 3 d after the treatment. Combination of DMS with immediate intraperitoneal treatment with spironolactone was even more effective in reducing the renal levels, and acted both by increasing the fecal and urinary excretion. The DMS treatment, as well as DMS + spironolactone in combination, could protect against kidney damage following injection of 30 mumol HgCl2/kg. Such treatment was essentially nontoxic.

Abstract
The ultrastructure of horny cells in the interfollicular epidermis of the hairless mouse and in the mouse with hair has been studied with particular emphasis on changes in the cytoplasm through the horny layer. Horny cells from the two strains have a similar appearance, and the horny layer can be divided into three sublayers, each with a different ultrastructure. It is suggested that in vivo the same arrangement of densely packed filaments and fibrils which represents the keratin pattern in the basal sublayer is preserved throughout the horny layer. However, the filaments and interfilamentous substance seem to undergo a continuous transformation, which possibly results in a disintegration of the filaments when desquamation of the uppermost cell takes place.

Abstract
This study comprised 62 outpatients with ulcerative colitis who underwent 64 colonoscopies. The disease activity was evaluated according to endoscopic and histological criteria. The results revealed a significant correlation between both the endoscopic as well as the histological gradings of disease activity and faecal calprotectin. The median faecal calprotectin levels in the control group (6 mg/l) and in the patients with no or low disease activity (11.5 mg/l) were significantly different (p < 0.0001). The median calprotectin level among patients with active disease was 68 mg/l which was significantly different from the latter group (p < 0.0001). Furthermore, we suggest that the degree of inflammation rather than the extent of the disease determined the faecal calprotectin levels. In conclusion, assessment of faecal calprotectin seems to be a marker of disease activity in patients with ulcerative colitis.
