Five-year survival predictive factors in patients with excessive alcohol intake and cirrhosis. Effect of alcoholic hepatitis, smoking and abstinence.

AIM: To evaluate 5-year survival predictive factors in hospitalised patients with excessive alcohol intake and cirrhosis, including in a multivariate analysis the severity of the liver disease, gastrointestinal bleeding, concomitant viral B or C infection, smoking status, presence of alcoholic hepatitis at inclusion and abstinence from alcohol during follow-up. METHODS: In a non-concurrent cohort study, 122 patients with excessive alcohol intake and cirrhosis were followed up at least five years or till death. Two patients were lost to follow-up. RESULTS: The 5-year survival rates were 43% in the 122 patients and 66%, 50% and 25% in Child-Pugh class A, B and C patients, respectively. In multivariate analysis, age (P = 0.01), Child-Pugh score (P = 0.0001), gastrointestinal bleeding (P = 0.01), presence of HBs Ag and/or anti-HCV (P = 0.03), smoking (P = 0.01), absence of histologically proven alcoholic hepatitis (P = 0.05) and persistent alcohol intake (P = 0.002) were associated with significantly increased risk ratios of death. CONCLUSIONS: In hospitalised patients with excessive alcohol intake and cirrhosis: (1) age, liver failure, gastrointestinal bleeding, concomitant viral B or C infection and persistent alcohol intake are independent poor prognostic markers, (2) smoking may contribute to the aggravation of cirrhosis, and (3) alcoholic hepatitis, being a potentially reversible cause of liver failure, has a favourable prognostic significance.

Cigarette smoking and hepatic lesions in patients with chronic hepatitis C.

A possible hepatotoxicity of cigarette smoke has been recently suggested by epidemiological and experimental studies. Our aim was to study the possible relationships between smoking and liver fibrosis and activity in patients with chronic hepatitis C. A cross-sectional study was performed in a group of 310 patients with chronic hepatitis C consecutively hospitalized for their first liver biopsy. The relationships between age, gender, alcohol consumption, route of contamination, tobacco consumption, and Knodell fibrosis and activity scores were examined in univariate, age-adjusted, and multivariate analyses. One hundred and seventy-six patients (57%) were current smokers. Smokers were younger (P <.001), more often of male gender (P =.001), more often alcohol consumers (P =.001), and more often had a history of intravenous drug use (P =.0001) than never smokers. Smoking was related to increased fibrosis and activity scores in age-adjusted (P =.009 and P =.005, respectively) and multivariate analyses (P =.03 and P =.04, respectively). Smoking increases the severity of hepatic lesions in patients with chronic hepatitis C.

Survival and prognostic factors in patients with severe alcoholic hepatitis treated with prednisolone.

BACKGROUND & AIMS: Corticosteroids have been shown to significantly decrease short-term mortality in patients with severe alcoholic hepatitis. However, independent factors associated with a favorable outcome and long-term survival are unknown. The aim of this study was to examine prognostic factors and long-term survival in patients with biopsy-proven severe alcoholic hepatitis. METHODS: Of 183 patients studied, 61 had been randomized in a previous trial; 32 of them were treated with prednisolone (group I) and 29 were not treated (group II); 61 were treated from the end of this randomized trial (group III); and 61 were simulated (group IV). RESULTS: At 1 year, survival in group I (69%; confidence interval [CI], 57%-81%) and group III (71%; CI, 55%-87%) was better than in the nontreated groups (group II, 41%; CI, 23%-59%; P = 0.01) (group IV, 50%; CI, 37%-63%; P = 0.05). At 2 years, survival was not significantly different. Treated patients with marked liver polymorphonuclear infiltrate had better 1-year survival (76%; CI, 64%-88%) than the others (53%; CI, 35%-71%; P = 0.05). Treated patients with polymorphonuclear counts of > 5500/mm3 had better 1-year survival (77%; CI, 65%-89%) than the others (40%; CI, 14%-66%; P = 0.003). In the 93 treated patients, liver polymorphonuclear infiltrate (P < 0.03) and polymorphonuclear count (P < 0.001) were independently correlated with 1-year survival. CONCLUSIONS: Prednisolone reduced mortality by at least 1 year. Liver polymorphonuclear infiltrate and polymorphonuclear count were independent prognostic factors.

Medical treatment for alcoholic liver disease.

The most effective treatment for alcoholic liver disease is abstinence from alcohol and it is the only treatment for patients with alcoholic fatty liver. Although many empirical therapeutic agents have been studied in the short-term and long-term treatment of alcoholic hepatitis, results have been mainly inconclusive. To date, only corticosteroids have proved to decrease the short-term mortality rate of patients with severe forms of acute alcoholic hepatitis. Corticosteroids are not beneficial to the majority of patients with mild or moderate forms of acute alcoholic hepatitis; such patients improve with abstinence from alcohol and general supportive measures and do not need a specific short-term treatment. Most long-term trials have only showed that most patients with alcoholic liver disease were neither abstinent nor compliant, and that long-term survival was strongly correlated to abstinence from alcohol. In one study, propylthiouracil decreased the long-term mortality rate of compliant patients with severe alcoholic liver disease who reduced their alcohol intake; however, further clinical trials are needed before propylthiouracil can be recommended. In another study, colchicine decreased the long-term mortality rate of cirrhotic patients, 45% of whom had alcoholic cirrhosis. Results were highly significant, and the need for further clinical trials of colchicine in the long-term treatment of alcoholic and non-alcoholic cirrhosis is imperative. Enteral nutrition should also be studied in severely malnourished cirrhotic patients, since it was shown to decrease the short-term mortality rate of such patients in a recent study.

A randomized trial of prednisolone in patients with severe alcoholic hepatitis.

BACKGROUND: Controlled trials have yielded inconsistent results with regard to the efficacy of corticosteroids in the treatment of alcoholic hepatitis. Three meta-analyses suggest that they may be effective in patients with encephalopathy who have severe liver disease. METHODS: We conducted a randomized, double-blind trial comparing 28 days of prednisolone treatment (40 mg per day) with placebo in 61 patients with biopsy-proved alcoholic hepatitis and either spontaneous hepatic encephalopathy (n = 19) or a discriminant-function value higher than 32. The discriminant function used was as follows: 4.6 (prothrombin time-control time [in seconds]) + serum bilirubin (in micromoles per liter)/17. Fifty-seven of the patients had evidence of cirrhosis on biopsy. The primary end point was death within two months. RESULTS: One patient was lost to follow-up after 56 days. Treatment was discontinued in two patients because of drug toxicity. By the 66th day after randomization, 16 of 29 placebo recipients had died (mean [+/- SE] survival, 45 +/- 8 percent), as compared with 4 of 32 prednisolone recipients (survival, 88 +/- 5 percent) (log-rank test, 10.9; P = 0.001). The survival advantage for prednisolone persisted after stratification according to center and the presence of encephalopathy, and after adjustment for prognostic factors in a proportional-hazards model. CONCLUSIONS: Treatment with prednisolone improves the short-term survival of patients with severe biopsy-proved alcoholic hepatitis.

Successful endoscopic obturation of gastric varices with butyl cyanoacrylate.

In 27 patients who had bled from esophagogastric varices, large-sized and/or actively bleeding gastric varices were endoscopically obturated with the tissue adhesive butyl cyanoacrylate. Active bleeding was stopped in six patients. Rebleeding occurred in 10 patients; in four patients, rebleeding was due to ruptured gastric varices, occurred early and was successfully treated by reinjection of gastric varices; in one patient, rebleeding was attributed to ulceration on an injected gastric varix. Eight patients died: two of rebleeding (from esophageal varices or undetermined source), four of sepsis and/or liver failure and two at home of undetermined cause. No specific complication due to injection of gastric varices was observed. The results obtained in this series of patients with gastric varices obturated by injection of butyl cyanoacrylate are much more satisfactory than those obtained in previously published series of patients with gastric varices treated by injection of sclerosants.

Sensitivity and specificity of microscopic examination of gallbladder bile for gallstone recognition and identification.

During cholecystectomy, gallbladder bile and gallstones were obtained from 77 patients and gallbladder bile was obtained from 39 patients free of stones (11 patients had biliary stenosis). According to their chemical composition, gallstones were classified as cholesterol (n = 46) or pigment (n = 31) stones. In patients with gallstones (a) cholesterol crystals better helped to identify cholesterol gallstones (sensitivity, 87%; specificity, 97%; positive predictive value, 97%) than did an abnormal cholesterol saturation index of bile (sensitivity, 93%; specificity, 48%; positive predictive value, 73%); (b) the presence of cholesterol crystals was significantly related to the cholesterol content of gallstones and the bile cholesterol saturation index; and (c) bilirubinate crystals, when present alone (without cholesterol crystals), were good predictors of pigment gallstones (sensitivity, 71%; specificity, 93%; positive predictive value, 88%). In the absence of stones, bilirubinate crystals were present in 9 of 28 patients without biliary stenosis (4 with alcoholic cirrhosis and 2 with alcoholic pancreatitis) and 8 of 11 patients with biliary stenosis. In the absence of stones, cholesterol crystals were present in 2 of 28 patients without biliary stenosis and in 4 of 11 patients with biliary stenosis, suggesting that bile stasis can induce cholesterol crystal formation.

Chronic Q fever hepatitis complicated by extensive fibrosis.

Liver involvement is common in acute and chronic Q fever and consists of nonspecific hepatitis and granulomas without fibrosis. We report the case of a patient suffering from chronic Q fever with nonspecific hepatitis and granulomas, in whom progressive development of extensive liver fibrosis was documented by repeated biopsies.

[Endoscopic obturation of esophagogastric varices with bucrylate. II. Morphologic study based on 12 autopsy cases]. / Obturation endoscopique des varices oeso-gastriques par le Bucrylate. II--Etude morphologique à partir de 12 cas autopsiés.

The authors report the results of postmortem histopathological studies in 12 patients who had been treated by endoscopic obliteration of esophagogastric varices with Bucrylate (isobutyl-2-cyanoacrylate). All patients had cirrhosis; 11 patients were Pugh classe C. Eleven patients had esophageal injections. Acute esophageal lesions were characterized by ulcerations in obliterated varices and diffusion of Bucrylate into the esophageal wall. Chronic lesions were characterized by disappearance of varices and Bucrylate, extending fibrosis of the esophageal wall and re-epithelialization of the mucosa. In one patient who had received gastric injections only, non ulcerated Bucrylate filled gastric varices were seen. Bucrylate seems to have a dual action on esophageal varices: immediate obliteration and acute necrosis of the vascular endothelium. Necrosis causes diffusion of Bucrylate through the esophageal wall, and later, secondary fibrosis whereas the product is progressively eliminated into the esophageal lumen.

[Endoscopic obturation of esophagogastric varices with bucrylate. I. Clinical study of 49 patients]. / Obturation endoscopique des varices oeso-gastriques par le Bucrylate. I--Etude clinique de 49 malades.

The authors report the results of endoscopic obliteration of recently bleeding esophagogastric varices with Bucrylate (isobutyl-2-cyanoacrylate) in 49 patients. Forty-five patients had cirrhosis; in all patients, propranolol was contraindicated or had failed, hepatocellular function was poor, or early rebleeding had occurred. In 15 cases, injections were made during active bleeding of esophageal or gastric varices; in 14 cases, the hemorrhage stopped immediately. The cumulative percentages of patients free of variceal rebleeding 1.6 and 12 months after inclusion were 88.63 and 58 p. 100 respectively. The cumulative percentages of patients surviving 1, 12 and 18 months after inclusion were 70, 53 and 46 p. 100 respectively. The cumulative percentages of survival at 6 months after inclusion were 100.63 and 13 p. 100 in grade A, B and C patients respectively. The major causes of death were liver failure and sepsis; autopsy revealed mediastinitis in 3 patients. Long-lasting esophageal strictures developed in two patients. This procedure differs from endoscopic sclerotherapy in that gastric varices can be adequately obliterated and the risk of early rebleeding seems to be decreased.

Alterations in isoprenaline sensitivity in patients with cirrhosis: evidence of abnormality of the sympathetic nervous activity.

Isoprenaline sensitivity and plasma catecholamine concentrations were studied to assess the sympathetic nervous activity in 13 patients with alcoholic cirrhosis and were compared with five controls. In patients with cirrhosis, the dose of isoprenaline required to increase the resting heart rate by 25 beats min-1 (chronotropic dose 25 or CD25) ranged from 2.50 to 34.73 micrograms (median: 4.47 micrograms) and was significantly higher than in controls (range: 0.66 to 2.76 micrograms, median: 1.34 micrograms). In cirrhotic patients, CD25 values were significantly correlated with plasma albumin concentration, resting heart rate and wedged hepatic venous pressure. In patients with cirrhosis, plasma noradrenaline concentrations ranged from 192 to 978 pg ml-1 (median: 444 pg ml-1) and adrenaline concentrations ranged from 5 to 183 pg ml-1 (median: 47 pg ml-1). No correlation was found between noradrenaline or adrenaline concentrations and CD25 values in cirrhotic patients. In conclusion, in patients with cirrhosis, beta-adrenoceptor responsiveness assessed by isoprenaline sensitivity is altered.

Dome formation in the human colon carcinoma cell line Caco-2 in culture. Influence of ouabain and permeable supports.

We studied formation of domes in cell monolayers of the human colon carcinoma cell line Caco-2 which has been shown to exhibit signs of enterocytic differentiation and transport properties. After a 24 hr incubation with 4 X 10(-8) M ouabain, the number of domes seen on Caco-2 cell monolayers grown on plastic dishes was not significantly altered. After a 90 min preincubation with ouabain, 86rubidium uptake by Caco-2 cells was inhibited by ouabain, indicating that the cells have an ouabain-sensitive Na+, K+-ATPase, while dome formation was unaffected by ouabain. Domes were observed in Caco-2 cell monolayers grown on Nuclepore filters when the pore size was 0.015 micron but not when it was 0.030 micron. Our results suggest that dome formation in the Caco-2 cell line could be independent of Na+, K+-ATPase activity and might be due to accumulation of molecules having an effective hydrodynamic radius comprised between 0.015 and 0.030 micron.

Partial hepatectomy in the treatment of Caroli's disease. Report of a case and review of the literature.

We describe a 28-yr-old woman who presented with severe, recurrent cholangitis due to Caroli's disease in association with congenital hepatic fibrosis. Cystic dilatation of the segmental bile ducts was diffuse, but predominated in the right lobe and left medial segment of the liver. Extended right lobectomy was followed by cessation of cholangitis. Partial hepatectomy should be considered for the treatment of Caroli's disease in the patients with severe, recurrent cholangitis in whom cystic dilatation of the intrahepatic bile ducts predominates in a part of the liver.
