Hepatitis C virus infection risk factors in patients admitted in hospital emergency departments in Picardy. Value of oriented screening based on recommendations of the 'Direction Générale de la Santé'.

OBJECTIVE AND DESIGN: Oriented hepatitis C virus (HCV) screening on the basis of transfusion, previous or current parenteral drug addiction, invasive procedures, and in family members of patients with hepatitis C, was recommended in France by the 'Direction Générale de la Santé' (DGS). The aim of this study was to estimate the frequency of these risk factors in patients admitted in hospital emergency departments in Picardy. METHODS: Between 1 June and 31 July 1996, physicians of the emergency units of seven hospitals in Picardy were asked to question admitted patients about risk factors mentioned in the DGS recommendations, and to suggest a screening test when at least one of these risk factors was present. RESULTS: Among 1648 patients, 68.7% had at least one of these risk factors. Screening was accepted by 723 patients, 58.7% of those with at least one risk factor, and more than 70% of those with history of transfusion and/or drug addiction. It was immediately performed in 451, and 2.4% had anti-HCV antibodies. The prevalence of anti-HCV antibodies was 1.5% in patients without history of transfusion or drug addiction and 7.9% in those with at least one of these two risk factors. CONCLUSION: Oriented screening based on transfusion or drug addiction history seems to have better efficiency than the screening policy recommended by the DGS. Poor reliability of answers about medical history was observed probably because of stress related to emergency circumstances. A screening test proposed to patients with these major risk factors by their usual physician would be probably more efficient.

Norfloxacin primary prophylaxis of bacterial infections in cirrhotic patients with ascites: a double-blind randomized trial.

BACKGROUND/AIMS: Norfloxacin is useful to prevent infections in hospitalized cirrhotic patients with low ascitic fluid protein concentrations. It is also effective in preventing the recurrence of spontaneous bacterial peritonitis. The aim of our study was to determine the efficacy of norfloxacin in the primary prophylaxis of gram-negative bacilli infections in cirrhotic patients with low ascitic fluid protein levels (<15 g/l). METHODS: One hundred and seven patients were randomized to receive norfloxacin (400 mg/day; n=53) or placebo (n=54) for 6 months. The patients had no history of infection since cirrhosis diagnosis and no active infection. RESULTS: The probability of gram-negative infection was significantly lower among patients treated with norfloxacin than among those treated with placebo. Six gram-negative bacilli infections occurred in the placebo group and none in the treatment group. Severe infections (spontaneous bacterial peritonitis, neutrocytic ascites and bacteremia) developed in nine patients in the placebo group (17%) and in one patient in the norfloxacin group (2%; p<0.03). There was no between-group difference in the overall rate of infection or in survival. In ten patients from the norfloxacin group, gram-negative bacilli not present in baseline stool cultures were transiently isolated in follow-up cultures. CONCLUSIONS: These data show that primary prophylaxis with norfloxacin for 6 months is effective in the prevention of infections caused by gram-negative bacilli in cirrhotic patients with low ascitic fluid total protein levels.

Randomized comparative multicenter study of hydroxyethyl starch versus albumin as a plasma expander in cirrhotic patients with tense ascites treated with paracentesis.

OBJECTIVE: Large-volume paracentesis associated with plasma volume expansion with albumin is an effective, safe, but costly therapy for ascites in patients with cirrhosis. The aim of this study was to compare the use of a synthetic plasma expander, hydroxyethyl starch (HES), with that of albumin. DESIGN: Sixty cirrhotic patients with ascites were studied. Patients were randomly assigned to be infused with either albumin (8 g/l of ascites removed, n = 33) or HES (200 ml/l of ascites removed, n = 27). None of the patients was treated with diuretics or had renal impairment or hyponatremia at entry. Clinical and laboratory data were obtained before and 1, 3 and 15 days after treatment. RESULTS: There were no significant differences in clinical and laboratory parameters between the two groups at entry into the study. None of the patients developed renal impairment during the trial. One patient (HES group) presented with hyponatremia. Plasma atrial natriuretic factor and aldosterone levels did not differ between the two groups at baseline or at 1 and 3 days after paracentesis. The volume of ascites removed did not differ between the albumin (7.9 +/- 4.4 l) and HES (6.9 +/- 5.3 l) groups. However, there was a significant difference in weight loss between the albumin and HES groups (7.9 +/- 5.2 kg vs 4.7 +/- 3.4 kg; p = 0.01). Clinical and laboratory parameters indicated that HES was well tolerated except for hypoalbuminemia. CONCLUSION: HES is well tolerated in patients with cirrhosis. There is no difference between HES and albumin in the prevention of complications related to large-volume paracentesis. The lesser degree of weight loss observed with HES needs further study.

Endoscopic sphincterotomy for suspected choledocholithiasis in patients with and without stones.

OBJECTIVE: To characterize a subgroup of patients treated with endoscopic sphincterotomy (ES) for a suspected common bile duct lithiasis (CBDL) that was not confirmed and to compare it with the subgroup with confirmed CBDL. METHODS AND RESULTS: Over 18 months, ES was successful in 245 consecutive patients (age 23-97, mean 75 yr, SE 17 yr) with suspected CBDL; 159 patients had CBDL (group 1), and 86 did not (group 2), as confirmed by CBD exploration. Fifty-nine percent of the patients in group 1 and 76.7% of the patients in group 2 had gallbladder in situ. Both groups were different for age (p < 0.001), prevalence of chronic alcoholism (p < 0.001), gallbladder in situ (p < 0.01), and gallbladder stones (p < 0.05). Patients from group 1 had two or more presenting symptoms suggestive of CBDL more often than patients from group 2 (p < 0.05), and pancreatitis was a more frequent presenting manifestation in group 2 (p < 0.0001). Overall morbidity and mortality were not different between groups, but acute cholecystitis developed in six patients from group 2 and in one patient from group 1 (p < 0.01). In a univariate analysis, only elevated alkaline phosphatase and a dilated common bile duct were positively discriminant for the diagnosis of CBDL; chronic alcoholism was negatively discriminant for the diagnosis of CBDL. In a multivariate analysis, only chronic alcoholism and a dilated bile duct were found to be independently discriminant. CONCLUSION: The risk of ES-related complications in the group without CBDL suggests that the selection of patients should be improved by a better use of preoperative criteria.

[Endoscopic drainage of pseudocysts of the pancreas. Study of 26 cases]. / Drainage endoscopique des pseudo-kystes du pancréas. Etude de 26 cas.

Endoscopic drainage of pancreatic pseudocysts has been proposed for several years as an alternative to surgical treatment. We report the results of 26 endoscopic cystostomies of pancreatic pseudocysts (13 cystoduodenostomies, 13 cystogastrostomies) performed in two specialized centres, from 1985 to 1991. The patients were divided into 3 groups (I, II, III) according to the pseudocysts' clinical presentation. The opening of the collection into digestive lumen was achieved in 22 cases; there were 3 puncture failures and 1 cystostomy was not performed because of a prior haemorrhagic puncture. Pain relief was obtained rapidly after cystodigestive drainage in 13 out of the 14 symptomatic patients. Three complications required surgery: 1 bleeding after cystoduodenostomy, 1 perforation and 1 peritonitis after cystogastrostomies. Two of them occurred after recutting a cystostomy. Two pseudocyst surinfections healed with antibiotic therapy. No deaths occurred due to the procedure. Among the 18 long-term followed-up patients (average = 33 months), 4 required surgery for persistence or relapse of pseudocysts. The results were excellent for the 14 other patients without any difference between cystoduodenostomies and cystogastrostomies, neither between the I, II and III groups. Each of the 5 cases with a digestive lumen-pseudocyst cavity thickness above 1 cm (measured on 20 CT scans) failed: 1 puncture failure, 3 complications, 1 relapse.

[Current results of endoscopic sphincterotomy for lithiasis of the common bile duct]. / Résultats actuels de la sphinctérotomie endoscopique pour lithiase de la voie biliaire principale.

Between January 1989 and June 1990, endoscopic sphincterotomy was performed in 308 consecutive patients with common bile duct stones (mean age: 74 years). Complete clearance of common bile duct was achieved at the first attempt in 65% of cases. This rate was significantly related to the size and the number of biliary stones. The success rate reached 97 percent after repeated endoscopic sessions (127 patients), mechanical lithotripsy (20 patients), extracorporeal or intracorporeal lithotripsy (18 and 11 patients, respectively). During the month following the endoscopic sphincterotomy, 39 patients (13%) developed one or more complications and 11 patients (3.7%) died. The complication rate was related to the time elapsed between biliary opacification and endoscopic sphincterotomy (P = 0.04) and between endoscopic sphincterotomy and total common bile duct clearance (P = 0.0007). No patient younger than 75 years died, but death occurred in 4.5% of the patients older than 75 years. Thirty patients (10%) developed endoscopic sphincterotomy-related complications. Cholangitis and bleeding were the most frequent complications (4 and 2%, respectively). Cholangitis occurred more frequently among the patients older than 75 (P < 0.05) or when transhepatic guided endoscopic sphincterotomy or intracorporeal lithotripsy was used (P < 0.005). Cholangitis led to death in 2 patients, 86 and 87 years old (0.7%). Endoscopic sphincterotomy related complications developed within 48 hours in all but 4 patients (2 patients with pancreatitis and 2 patients with cholecystitis).

[Palliative treatment by endoprosthesis of icterus caused by distal biliary tumoral obstruction]. / Traitement palliatif par endoprothèse des ictères par obstacle tumoral biliaire sous-hilaire.

Between March 1982 and December 1987, 466 patients (256 women, 210 men, mean age 73 years) with tumor obstruction of the common bile duct were referred to our department. The causes of obstruction were carcinoma of the pancreas (298 patients), carcinoma of the ampulla of Vater (32 patients) and carcinoma of the common bile duct (136 patients). Endoscopical insertion of a biliary prosthesis was initially possible in 377 patients (81%). In case of failure, patients were referred to the radiologist for percutaneous drainage. Successful drainage was obtained in 58 patients with an overall success rate of 93% (435 patients). Endoscopic replacement was necessary in 170 cases for 114 patients and was successful in 155 (91%). Pruritus was relieved in 89% of the patients. Serum bilirubin levels decreased more than 75% after initial endoscopic endoprosthesis, repeated endoscopic endoprosthesis and percutaneous prosthesis insertion in 80%, 79%, and 62% of the patients, respectively. Short term complications of endoscopic endoprosthesis occurred in 28% of patients with a mortality rate of 8%. Percutaneous prosthesis complications occurred in 33% of patients with a mortality rate of 11%. In the long term, cholangitis was the main complication and occurred in 27% of patients with a delay of 103 +/- 105 days. Intestinal obstruction was observed in 7% of patients. The average life expectancy of endoscopic endoprosthesis and percutaneous prosthesis was 109 +/- 157 and 92 +/- 101 days, respectively. The average life expectancy of patients was 163 +/- 224 days.(ABSTRACT TRUNCATED AT 250 WORDS)

Does elective sclerotherapy improve the efficacy of long-term propranolol for prevention of recurrent bleeding in patients with severe cirrhosis? A prospective multicenter, randomized trial.

We conducted a prospective, multicenter, randomized trial to compare the efficacy of sclerotherapy plus propranolol with that of propranolol alone in the prevention of recurrent gastroesophageal bleeding in severely cirrhotic patients. For 2 yr (1987 to 1988) 131 patients (96% of whom were alcoholic) with Child-Pugh class B or C cirrhosis (56% were class B and 44% were class C) were randomly assigned to one of our two treatment groups after cessation of variceal bleeding, without hemostatic sclerosis, and were observed for at least 2 yr. Treatment observance was good in 89% of cases; alcohol withdrawal was observed in 62% of cases. Sclerotherapy was performed weekly with 1% polidocanol, and variceal obliteration was obtained in 83% of cases, in a mean number of four sessions. The cumulative percentages (expressed as mean +/- S.D.) of recurrent bleeding at 2 yr were 42% +/- 6% for propranolol plus sclerotherapy and 59% +/- 6% for propranolol alone (a nonsignificant difference). Twenty-eight patients from the propranolol group but only 12 patients from the propranolol-plus-sclerotherapy group had recurrent bleeding from esophageal variceal rupture (p less than 0.01). The total number of blood units per patient with recurrent bleeding was slightly but not significantly more important in the propranolol group (8 +/- 7) than in the propranolol-plus-sclerotherapy group (5 +/- 5; p = 0.09).(ABSTRACT TRUNCATED AT 250 WORDS)

Management of malignant hilar biliary obstruction by endoscopy. Results and prognostic factors.

Between January 1983 and December 1987, 103 patients who had hilar biliary obstruction (59 men, 44 women, median age 73 years) were referred to our institution. The causes of hilar biliary obstruction were carcinoma of the bile ducts (55), hepatic metastases or hepatocellular carcinoma (30), and carcinoma of the gallbladder (18). When endoscopic retrograde cholangiography was performed, the stricture was classified as type I in 28%, type II in 41%, and type III in 31% of the patients. In 92 patients, we tried to insert endoscopically a 10, 11, or 12 F Amsterdam type prosthesis; it proved possible in 66 (74%), and the prosthesis proved functional without further procedure in 49 cases (53%); no combined percutaneous and endoscopic method was used. At death or discharge, 45 patients (49%) had a successful drainage. Cholangitis was the main procedure-related complication and occurred in 25 patients. The 30-day mortality was 43%. Results varied according to type of stenosis: successful drainage was performed in 15% of the patients with type III stenosis, compared with 86% when the stenosis was of type I. Under a multivariate analysis the independent prognostic factors of 30-day mortality were: (1) development of infectious complications after endoscopic attempt at drainage (P less than 0.0001), and (2) absence of successful drainage (P less than 0.0001). In conclusion, endoscopic endoprosthesis placement allows a sufficient drainage in 53% of the cases. In type III stenosis, the high rate of 30-day mortality leads us the conclusion that endoscopic drainage must be avoided.

Cirrhosis as an independent risk factor for colonic adenomas.

This study aimed to determine the relation between cirrhosis and colorectal adenomatous polyps after adjustment for alcoholism and other confounding variables. Four groups of patients aged 40 years or above were studied. Group I included 100 consecutive outpatients with irritable bowel syndrome, group II 100 consecutive alcoholic inpatients without cirrhosis, group III 100 consecutive inpatients with alcoholic cirrhosis, and group IV included 36 consecutive inpatients with non-alcoholic cirrhosis. All patients underwent colonoscopy. The prevalence of adenomatous polyps was 13% in group I, 26% in group II, 58% in group III, and 22% in group IV (p less than 0.001). The prevalence of adenomatous polyps was greater in patients with cirrhosis than in those patients without (48.5% v 19.5%). This difference remained significant after successive adjustment for alcoholism, sex, age, smoking, and serum cholesterol. The prevalence of adenomatous polyps was greater in alcoholic patients than in non-alcoholic patients (42% v 15.4%) (p less than 0.001). This difference remained significant after successive adjustment for cirrhosis, sex, age, smoking, and serum cholesterol. These results suggest that cirrhosis is an independent risk factor for colorectal adenomatous polyps and confirm that alcoholism increases this risk.

[Treatment of ascites in patients with liver cirrhosis without neither hyponatremia nor renal insufficiency. Results of a randomized study comparing diuretics and punctures compensated by albumin]. / Traitement de l'ascite chez les malades atteints de cirrhose sans hyponatrémie ni insuffisance rénale. Résultats d'une étude randomisée comparant les diurétiques et les ponctions compensées par l'albumine.

Previous studies have suggested that treatment of ascites in cirrhotic patients by repeated paracenteses and albumin infusion is fast, effective and safe. In one of these studies including patients with hyponatremia or renal impairment, this treatment was associated with a reduction of duration of hospital stay in comparison with large dose diuretics. The aim of this randomized study was to compare paracentesis with albumin perfusion and low dose diuretics in cirrhotic patients with ascites, but without hyponatremia or renal impairment. Twenty-six patients (group 1) were treated with paracentesis (4 L/day) and 27 patients (group 2) were treated with spironolactone (225 to 300 mg/day), associated with furosemide (40 to 80 mg/day), when inefficient alone. Ascites and peripheric edema disappeared more rapidly in group 1 than in group 2, 8.6 +/- 9.6 vs 13.5 +/- 6.7 days (P = 0.001) and 4.1 +/- 2.6 vs 10.5 +/- 6.5 days (P = 0.001) respectively. During hospitalisation, the incidence of complications was higher in group 2 than in group 1: 56 vs 26% (P = 0.03). Hyponatremia occurred in 30% of patients in group 2 and 4% of patients in group 1 (P = 0.04). The duration of hospital stay was shorter in group 1 (15.0 +/- 10.4 days) than in group 2 (21.0 +/- 11.7 days) (P = 0.007). During follow-up, ascites reappeared in 32% of patients in group 1 and 57% of patients in group 2 (P = 0.09). At 3 months, one patient in group 1 and 2 patients in group 2 developed spontaneous peritonitis whereas survival was similar in both groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Asymptomatic bacterascites: is it spontaneous bacterial peritonitis?

Asymptomatic bacterascites is defined as the presence of bacteria in ascitic fluid without clinical features of peritonitis or increased ascitic fluid polymorphonuclear cells. Asymptomatic bacterascites is a controversial entity, and little information is available regarding its spontaneous evolution. Clinical features, bacteriological data and outcome in 22 cirrhotic patients with asymptomatic bacterascites are reported and are compared with those of a group of 36 cirrhotic patients with spontaneous bacterial peritonitis. Eleven patients had gram-negative bacteria and 11 had one gram-positive bacteria. Only in three patients (13.6%) did peritonitis develop. Twelve patients received no antibiotic therapy, and in none did peritonitis develop. At 1 month, 27% of patients with asymptomatic bacterascites had died. Patients with asymptomatic bacterascites had less-severe liver disease; they more frequently had gram-positive bacteria in ascitic fluid and had a lower 1-mo mortality rate than did patients with spontaneous bacterial peritonitis. We conclude that asymptomatic bacterascites is usually the transient residence of bacteria in ascitic fluid. Peritonitis rarely develops in patients with asymptomatic bacterascites and, in most of them, antibiotic therapy is not required.

[Long-term outcome of alcoholic patients after a stay in a hospital hepatogastroenterology unit]. / Devenir des malades alcooliques après une hospitalisation en hépato-gastroentérologie.

The long term results of psychologically oriented treatment for alcoholism were evaluated in 147 patients hospitalized in a liver unit and followed for 1-5 years. Twenty-three percent of the patients were hospitalized for treatment of alcoholism, while 61 percent were hospitalized for alcohol-related disease. The main patient characteristics were: males: 71 percent; age: 48 +/- 10 years (mean +/- SD); alcoholic cirrhosis: 48 percent; initial request for help in abstinence: 9 percent; and unemployment: 35 percent. During the hospitalization (16 +/- 10 days), each patient had 1 to 4 psychotherapeutic interviews. Seventy-four percent of patients responded to follow-up after discharge and contact was maintained in 23 percent of patients 2 years thereafter. The only two independent prognostic variables for long-term follow up were the need for medical supervision (P less than 0.001) and employment (P less than 0.005) (Cox model). Only 10 percent of the patients attended a post-hospitalisation psychotherapeutic program. Among the 108 patients who were followed, 35 percent were totally abstinent immediately after discharge and 17 percent did not relapse during the 2 following years. Relapse was unpredictable according to any of the initial variables. Half of the patients who were abstinent immediately after discharge remained totally so at long-term follow-up. Total abstinence was obtained for 39 percent of patients during a mean period of 27 +/- 34 months. Medical, social, or psychological improvement was observed more often in abstainers (61 percent) than in non abstainers (11 percent, P less than 0.001). We conclude that: a) long-term follow-up and abstinence were infrequently obtained in unselected alcoholic patients hospitalized in a liver unit; b) no initial criteria could predict the alcoholic relapse or select patients for alcoholism treatment; c) long-term results seemed more favorable when the patients where totally abstinent immediately after discharge.

A randomized trial of hepatic arterial chemoembolization in patients with unresectable hepatocellular carcinoma.

A randomized trial of hepatic arterial chemoembolization was conducted in 42 patients with unresectable hepatocellular carcinoma. These patients represented 41% of patients with hepatocellular carcinoma seen during the inclusion period. In the remaining 59%, 9% had resectable tumours and 50% had unresectable tumours with contraindication for chemoembolization. Patients received either repeated chemoembolization with gelfoam powder and doxorubicin (group 1) or symptomatic treatment (group 2). There was no difference in age, prevalence of cirrhosis or staging according to Okuda between the two groups of patients. A complete tumour response (assessed by arteriography, ultrasonography and serum alphafetoprotein) was observed in four patients, and a partial response in three other patients from group 1. Actuarial survival rates were 33 and 24% in group 1 and 52 and 31% in group 2 at 6 and 12 months, respectively (differences were not significant--logrank test). With the treatment used in our study, chemoembolization did not prolong the survival time of patients with unresectable hepatocellular carcinoma. There were, however, some complete or partial responses. The high spontaneous 1-year survival rate of untreated patients was probably due to the exclusion of the most severely ill patients. Our results do not support the use of this method of chemoembolization in the treatment of hepatocellular carcinoma.

Nodular regenerative hyperplasia of the liver, peliosis hepatis, and perisinusoidal fibrosis. Association with angioimmunoblastic lymphadenopathy and severe hypoxemia.

Three different liver lesions were found in a 20-year-old woman with angioimmunoblastic lymphadenopathy. The lesions included nodular regenerative hyperplasia of the liver, perisinusoidal fibrosis, and peliosis hepatis. It is suggested that the association of angioimmunoblastic lymphadenopathy with this broad spectrum of liver lesions was not fortuitous.

Culture-negative neutrocytic ascites: a less severe variant of spontaneous bacterial peritonitis.

The clinical signs and symptoms, the biological data and the prognosis of 38 cirrhotic patients with culture-positive spontaneous bacterial peritonitis and 15 cirrhotic patients with culture-negative neutrocytic ascites were compared. The diagnosis of culture-negative neutrocytic ascites was based on the following criteria: an ascitic fluid polymorphonuclear count greater than 250/mm3, a negative ascitic fluid culture and the absence of previous antibiotic therapy and intraabdominal source of infection. All patients were treated by antibiotic therapy. There were no differences in clinical signs and symptoms and Pugh grading between the two groups of patients. Serum creatinine and prevalence of positive-blood culture were higher in spontaneous bacterial peritonitis. Patients with culture-positive spontaneous bacterial peritonitis had a higher ascitic fluid polymorphonuclear count and a lower ascitic fluid pH. Mortality was higher in patients with culture-positive spontaneous bacterial peritonitis than in patients with culture-negative neutrocytic ascites (relative risk: 2.6, p less than 0.01): cumulative mortality was, respectively, 50% and 20% at 1 months, 61% and 33% at 6 months, 75% and 41% at 1 year. The higher mortality observed in patients with culture-positive spontaneous bacterial peritonitis persisted after hospitalization (relative risk: 3, p less than 0.03). Our results suggest that culture-negative neutrocytic ascites is a less severe variant of spontaneous bacterial peritonitis.
