Cholangiopathy in critically ill patients surviving beyond the intensive care period: a multicentre survey in liver units.

BACKGROUND: The outcome of cholangiopathy developing in intensive care unit (ICU) is not known in patients surviving their ICU stay. AIM: To perform a survey in liver units, in order to clarify the course of cholangiopathy after surviving ICU stay. METHODS: The files of the liver units affiliated to the French network for vascular liver disease were screened for cases of ICU cholangiopathy developing in patients with normal liver function tests on ICU admission, and no prior history of liver disease. RESULTS: Between 2005 and 2015, 16 cases were retrieved. Extensive burns were the cause for admission to ICU in 11 patients. Serum alkaline phosphatase levels increased from day 11 (2-46) to a peak of 15 (4-32) × ULN on day 81 (12-511). Magnetic resonance cholangiography showed irregularities or frank stenosis of the intrahepatic ducts, and proximal extrahepatic ducts contrasting with a normal aspect of the distal common bile duct. Follow-up duration was 20.6 (4.7-71.8) months. Three patients were lost to follow-up; 2 patients died from liver failure and no patient was transplanted. One patient had worsening strictures of the intrahepatic bile ducts with jaundice. Nine patients had persistent but minor strictures of the intrahepatic bile ducts on MR cholangiography, and persistent cholestasis without jaundice. One patient had normal liver function tests. CONCLUSIONS: In patients surviving their ICU stay, ICU cholangiopathy is not uniformly fatal in the short term or clinically symptomatic in the medium term. Preservation of the distal common bile duct appears to be a finding differentiating ICU cholangiopathy from other diffuse cholangiopathies.

[Natural history of non alcoholic and non familial chronic pancreatitis. Results of a multicentre study]. / Evolution de la pancréatite chronique non alcoolique et non familiale.Résultats d'une étude multicentrique.

UNLABELLED: The natural history and complications of non alcoholic chronic pancreatitis (NACP) is poorly understood compared to that of alcoholic chronic pancreatitis (ACP). PATIENTS AND METHODS: From April 1993 to April 1996, 77 patients with NACP were prospectively evaluated in 17 French centres. This population was compared to a cohort of 417 patients with ACP. RESULTS: No significant difference was observed with respect to mean age between NACP and ACP (43 +/- 20 vs 44 +/- 11 years, respectively). The median patient follow-up time was also comparable: 7 years (1-28) and 6 years (1-34) respectively for NACP and ACP. There were significantly more males in the ACP group (9/1 in ACP group and 1.3/1 in NACP group; P<10(- 7) ). Patients with NACP were less likely to have calcifications (58% vs 77%; P=0.01), pseudocysts (19 vs 47%, P<0.001), portal vein thrombosis (5 vs 16%, P<0.02). Importantly, patients with NACP required less surgical procedures than those with ACP (26% vs 44%, P=0.004). The actuarial death rate at 15 years was 0% in the NACP group compared to 20.5% in those with ACP (no CP related death). CONCLUSION: NACP has a less severe disease progression, fewer complications and requires less surgical interventions than ACP. The lower actuarial survival rate in patients with ACP correlates with the extra-pancreatic complications encountered in patients with alcohol related diseases and not with the evolution of CP itself.

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.

[Rapid progress of cirrhosis in hepatitis C: the role of age at the time of viral contamination]. / Rapidité d'évolution vers la cirrhose après hépatite C: influence de l'âge au moment de la contamination par le virus.

OBJECTIVE: The aim of this study was to assess predictive factors for the progression to liver cirrhosis in hepatitis C. METHODS: One hundred thirty six patients (79 men; 57 women; mean age 39 years) with transfusion or intravenous drug use-associated hepatitis C virus (HCV) infection were studied. Sex, cause of infection, duration of contamination, and genotype were studied as predictive factors of progression to liver cirrhosis. RESULTS: One hundred twenty three patients presented with chronic hepatitis without cirrhosis and 13 had cirrhosis. At the time of liver biopsy, rates of cirrhosis were: 0% before 40 years, 10% between 40 and 60 years, and 47% after 60 years. (p < 0.05). Rates of cirrhosis according to the age at the time of contamination were as follows: 3% before 30 years; 16% between 30 and 50 years; 46% after 50 years even though duration of the disease was comparable in the three groups. In multivariate analysis, two independent factors were associated with liver cirrhosis: age at contamination and duration of infection. CONCLUSION: Duration of infection and especially age at contamination seem better correlated with the probability of cirrhosis than the route of transmission or the genotype 1b. The results of this study suggest that progression to cirrhosis is slower in cases of contamination before 30 years of age than later on. Age at the time of contamination is an important predictive factor of progression to cirrhosis.

Frequency and risk factors of recurrent pain during refeeding in patients with acute pancreatitis: a multivariate multicentre prospective study of 116 patients.

BACKGROUND/AIMS: The period of refeeding in patients with acute pancreatitis is critical because they may have pain relapse. A multicentre, multidimensional, prospective study was performed to assess the frequency and the risk factors of pain relapse in these patients. METHODS: Patients were included if they had acute pancreatitis severe enough to stop oral feeding for more than 48 hours. Clinical, biochemical, radiological, and therapeutic data were prospectively recorded and analysed by unidimensional and multidimensional analysis. The moment to refeed patients was chosen by the clinician but the diet was the same in all centres. RESULTS: A total of 116 patients were included with a Ranson's bioclinical score > or = 3 in 35% and a Balthazar's CT score > or = D in 42%. The cause of acute pancreatitis was biliary in 47% and alcohol misuse in 31%. During the oral refeeding period, 21% of the patients had pain relapse. This occurred on days 1 and 2 in 50% of patients. The duration of the painful period was longer in patients who relapsed than in others (p < 0.002). Pain relapse occurred in 39% of patients with a serum lipase concentration > 3x the upper limit of the normal range the day before refeeding and in 16% of other patients (p < 0.03). Patients with higher Balthazar's CT scores had pain relapse more often than the others (p < 0.002). None of the therapeutic procedures significantly modified the frequency of pain relapse. Using multidimensional analysis, Balathazar's CT score, period of pain, and serum lipase concentration the day before refeeding were independently associated with an increased risk of pain relapse. At a threshold of 0.5, a logistic score had a 37% sensitivity, 95% specificity, and 83% accuracy to predict pain relapse. Pain relapse nearly doubled total hospital stay and hospital stay after the first attempt at oral refeeding. CONCLUSION: Pain relapse occurred in one fifth of the patients with acute pancreatitis during oral refeeding and was more common in patients with necrotic pancreatitis and with longer periods of pain. The results of this study can be used to predict high risk patients and are a first step in the prevention of pain relapse.

Orally administered omeprazole versus injection therapy in the prevention of rebleeding from peptic ulcer with visible vessel. A multicenter randomized study.

Endoscopic injection therapy significantly reduces the risk of bleeding relapse in patients with digestive hemorrhage due to peptic ulcers associated with a visible vessel. Profound and sustained acid inhibition by proton pump inhibitors may generate optimal conditions for clotting and prevent bleeding relapse. Over a one-year period, 52 patients presenting with digestive hemorrhage, in whom emergency endoscopy showed a peptic ulcer with a non-bleeding visible vessel, were enrolled in a multicenter randomized study comparing oral omeprazole, 40 mg per day (n = 31) vs adrenaline (1:10,000) plus polidocanol (1%) injection associated with oral ranitidine 300 mg per day (n = 21). Rebleeding occurred in 15/52 (29%) patients: 8/31 (26%) in the omeprazole group with 6 major hemorrhages (19%), and in 7/21 (33%) in the injection group with 3 major hemorrhages (14%); the differences were not significant. No difference was observed between omeprazole and injection group in terms of volume of transfused blood (2.03 +/- 1.5 vs 3.1 +/- 0.9 blood units), need for hemostatic surgery (9.6% vs 14.3%), mortality (19.3% vs 14.3%) and mean hospital stay (11.5 days both groups). This study suggests that oral omeprazole, 40 mg per day, has an efficacy comparable to injection therapy in reducing the bleeding relapse from non bleeding peptic ulcers associated with visible vessel.

[Asymptomatic cystic dilatation of the choledochus in an adult]. / Dilatation kystique asymptomatique du cholédoque chez un adulte.

A congenital choledochal cyst, type Ia according to Todani's classification, was discovered fortuitously in a 54-year old man by abdominal sonography. The patient had no biliary symptoms, and liver tests were normal. Excision of the cyst was performed because of the theoretical risk of cholangiocarcinoma. Recovery was uneventful.

Fipexide-induced fulminant hepatitis. Report of three cases with emergency liver transplantation.

Fipexide belongs to a new class of cognition activators and is noted for its lack of amphetamin-like side effects. We describe three patients who developed fulminant hepatic failure less than 2 months after beginning fipexide administration. The mean interval from the onset of jaundice to the onset of encephalopathy was 8 days. Emergency liver transplantation was undertaken when factor V was 20% of normal or less and coma developed. All patients were transplanted less than 1 week after the onset of encephalopathy. Two survived and one died immediately after transplantation. Histologic examination of the livers revealed massive liver cell necrosis, predominantly centrilobular, and a moderate inflammatory infiltrate within the portal spaces. We conclude that fipexide can induce massive liver cell necrosis and fulminant liver failure. As a result of this life-threatening complication, reconsideration of the indications for this drug is warranted.

Internal radiation therapy for hepatocellular carcinoma. Results of a French multicenter phase II trial of transarterial injection of iodine 131-labeled Lipiodol.

Preliminary Phase I trials have shown iodine 131 (131I)-Lipiodol (ethiodized oil; Laboratoires Guerbet, Aulnaysous-Bois, France) to be well tolerated and most likely effective in the treatment of hepatocellular carcinoma (HCC). In this multicenter Phase II trial, the authors tested the feasibility and reproducibility of this treatment in other medical institutions and evaluated its efficacy in 50 patients with unresectable Stage I or II HCC, by the classification of Okuda et al. The authors studied 47 men and 3 women (63.9 +/- 7.1 years old) with Stage I (n = 18) or II (n = 32) HCC, by the classification of Okuda et al., which was verified by histologic findings (n = 25), cytologic findings (n = 11), or association of a tumor with alpha-fetoprotein serum values greater than 500 micrograms/l (n = 14). This multicenter trial (1) confirmed that the 131I-Lipiodol treatment is well tolerated; (2) showed that there is a high reproducibility of results with respect to other institutions and an objective tumor response in 40% of the cases; and (3) indicated the necessity of performing a randomized controlled study.

[Portal vein thrombosis and hereditary protein C deficiency. Presentation of a case and review of the literature]. / Thrombose portale et déficit héréditaire en protéine C. Présentation d'un cas et revue de la littérature.

The authors report the case of a 51 year-old man, without any personal or familial history of thromboembolism, presenting with abdominal pain. Portal vein thrombosis was demonstrated by ultrasonography and arteriography. The patient had neither esophageal varices or congestive gastropathy. No cause for portal vein thrombosis was detected. Type I protein C deficiency was demonstrated in this patient as well as in his asymptomatic sister. The presence of a (fortuitously?) associated increase in platelet aggregability initially led to a trial regimen of aspirin (300 mg per day); abdominal pain resolved, and a partial regression of portal vein thrombosis was demonstrated on ultrasonograms six months later; no further complications occurred during the 4-year follow-up period. The 13 previously published cases of protein C deficiency-associated portal vein thrombosis are reviewed.

Sinusoidal portal hypertension in hepatic amyloidosis.

Hepatic venous catheterisation and transvenous liver biopsy were performed in five patients with hepatic amyloidosis. In three patients, hepatic venous pressures were normal and histological examination of the liver biopsy specimen showed discrete and sparse perisinusoidal amyloid deposits. In the other two, however, the gradient between wedged and free hepatic venous pressures was increased (12 and 16 mmHg; normal 1-4 mmHg) and amyloid deposits were abundant and diffuse in the Disse's space. This study shows that portal hypertension in patients with hepatic amyloidosis is of the sinusoidal type and is related to the reduction of vascular space of hepatic sinusoids by massive perisinusoidal amyloid deposits. Furthermore, portal hypertension is associated with a poor prognosis in patients with hepatic amyloidosis.
