BACKGROUND AND AIMS:The therapeutic potential of ursodeoxycholic acid (UDCA) treatment in primary biliary cirrhosis (PBC) remains controversial. In addition, relatively few data have been reported on the outcome of patients who have been treated long term. The aim of the present study was to document long-term survival of a prospectively followed large cohort of UDCA treated patients in comparison to that predicted by the Mayo model and of a matched control cohort of the Dutch population.METHODS:Two hundred ninety-seven patients were included and followed during a median period of 68 (range 3–126) months until death or the end of the study.RESULTS:Survival free of transplantation (1 yr 99.7%, 5 yr 87%, and 10 yr 71%) was significantly better than predicted by the Mayo model (p = 0.01). However, for patients with abnormal serum bilirubin and/or albumin concentrations at entry, observed and predicted survival did not significantly differ. Compared with survival for a standardized cohort of the Dutch population, observed survival for the total group was significantly decreased (p = 0.0003); for noncirrhotic patients and patients with normal entry bilirubin and albumin concentrations survival was comparable. Serum bilirubin and albumin concentrations were the prognostic factors most consistently associated with survival.CONCLUSIONS:A 10-year prognosis for most UDCA-treated patients with PBC, i.e., those with a normal bilirubin and albumin concentration, is comparable to that of a matched general population. Our finding that observed survival was significantly better than predicted by the Mayo model may suggest that this model did not accurately predict prognosis in our cohort. Alternatively, this finding indicates an important therapeutic effect of long-term UDCA treatment in PBC, particularly in patients with noncirrhotic, nonadvanced disease.

BackgroundFatigue is a major clinical problem in many patients with primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC). An effective treatment has not been defined. Recently, a large proportion of patients with these diseases was found to have symptoms of depression. Because fatigue is a frequent symptom of depression and there is some evidence that treatment with an antidepressant improves fatigue in patients with fibromyalgia, we hypothesised that the antidepressant fluvoxamine might improve fatigue related to PBC and PSC.MethodsFatigued patients were randomised to receive fluvoxamine (75 mg BID) or placebo for a six-week period. Fatigue and quality of life were quantified using a visual analogue scale, the Fisk Fatigue Severity Scale, the Multidimensional Fatigue Inventory and the SF-36.ResultsSeventeen and 16 patients were allocated to fluvoxamine and placebo, respectively. There was no statistically significant beneficial effect of fluvoxamine on fatigue or quality of life. The median VAS scores in the fluvoxamine and placebo groups were 7.40 and 7.45 at day 0, 6.9 and 7.15 at day 14, 7.45 and 7.65 at day 42 and 7.8 and 8.0 four weeks after treatment discontinuation.ConclusionWe found no evidence for a beneficial effect of fluvoxamine on fatigue in these patients with cholestatic liver disease and severe chronic fatigue.

BackgroundIn primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) fatigue is a major clinical problem. Abnormal amino acid (AA) patterns have been implicated in the development of fatigue in several non-hepatological conditions but for PBC and PSC no data are available. This study aimed to identify abnormalities in AA patterns and to define their relation with fatigue.MethodsPlasma concentrations of tyrosine, tryptophan, phenylalanine, valine, leucine and isoleucine were determined in plasma of patients with PBC (n = 45), PSC (n = 27), chronic hepatitis C (n = 22) and healthy controls (n = 73). Fatigue and quality of life were quantified using the Fisk fatigue severity scale, a visual analogue scale and the SF-36.ResultsValine, isoleucine, leucine were significantly decreased in PBC and PSC. Tyrosine and phenylalanine were increased (p < 0.0002) and tryptophan decreased (p < 0.0001) in PBC. In PBC, but not in PSC, a significant inverse relation between tyrosine concentrations and fatigue and quality of life was found. Patients without fatigue and with good quality of life had increased tyrosine concentrations compared to fatigued patients. Multivariate analysis indicated that this relation was independent from disease activity or severity or presence of cirrhosis.ConclusionIn patients with PBC and PSC, marked abnormalities in plasma AA patterns occur. Normal tyrosine concentrations, compared to increased concentrations, may be associated with fatigue and diminished quality of life.

Bacterial cholangitis causing secondary sclerosing cholangitis: A case report

Pieter Ter Borg; Henk R. van Buuren; Annekatrien Ctm Depla

BackgroundAlthough bacterial cholangitis is frequently mentioned as a cause of secondary sclerosing cholangitis, it appears to be extremely rare, with only one documented case ever reported.Case presentationA 48-year-old woman presented with an episode of acute biliary pancreatitis that was complicated by pancreatic abcess formation. After 3 months she had an episode of severe pyogenic (E. Coli) cholangitis that recurred over the subsequent 7 months on a further two occasions. Initially, cholangiography suggested the presence of extra-biliary intrahepatic abcesses while repeated investigations demonstrated development of multiple segmental biliary duct strictures. After maintenance antibiotic treatment was started, no episodes of cholangitis occurred over a 14-month period.ConclusionsSclerosing cholangitis can rapidly develop after an episode of bacterial cholangitis. Extra-biliary involvement of the hepatic parenchyma with abcess formation may be a risk factor for developing this rare but particularly severe complication.

Pregnancy and ABCB4 gene mutation: risk of recurrent cholelithiasis

Jan H Elderman; Pieter Ter Borg; Jan Dees; Adriaan Dees

Cholelithiasis is a common problem in the Western world. Recurrent gallstones after cholecystectomy, however, are rare. We describe a case of a young woman with recurrent gallstones after a laparoscopic cholecystectomy leading to cholangitis during pregnancy. Additional testing revealed an ATP-binding cassette B4 (ABCB4) gene mutation. ABCB4 gene mutations leading to a multidrug resistance (MDR)3-P-glycoprotein deficiency are related to, among other diseases, recurrent cholelithiasis. Medical treatment consists of administering oral ursodeoxycholic acid. If untreated, MDR3 deficiency can lead to progressive liver failure requiring liver transplantation.

G A A b st ra ct s lesion does not appear to impact the frequency of change in diagnosis. Based on the potential to make an accurate histological diagnosis and thus allowing for better patient selection, EMR should be considered as the first step in the management of BE-associated early neoplasia irrespective of presence or absence of endoscopically visible lesions.

BACKGROUND Covered esophageal self-expandable metal stents (SEMSs) are currently used for palliation of malignant dysphagia. The optimal extent of the covering to prevent recurrent obstruction is unknown. Therefore, we aimed to compare fully covered (FC) versus partially covered (PC) SEMSs in patients with incurable malignant esophageal stenosis. METHODS In this multicenter randomized controlled trial, 98 incurable patients with dysphagia caused by a malignant stricture of the esophagus or cardia were randomized 1:1 to an FC-SEMS or PC-SEMS. The primary outcome was recurrent obstruction after endoscopic SEMS placement. Secondary outcomes were technical and clinical success, adverse events, and health-related quality of life (HRQoL). Patients were followed until 6 months after SEMS placement or to SEMS removal, second SEMS insertion, or death, whichever came first. RESULTS Recurrent obstruction after SEMS placement was similar for both types of stents: 19 % for FC-SEMSs and 22 % for PC-SEMSs (P = 0.65). The times to recurrent obstruction did not differ. The frequency of adverse events was similar between the two groups, with major adverse events occurring in 38 % and 47 % of patients for FC-SEMSs and PC-SEMSs, respectively (P = 0.34). No significant differences were seen in technical success, improvement of dysphagia, and HRQoL. Proximal esophageal stenosis and female sex were independently associated with recurrent obstruction and/or major adverse events. CONCLUSIONS Esophageal FC-SEMSs did not reveal a lower recurrent obstruction rate compared with PC-SEMSs in the palliative management of malignant dysphagia.

Background and study aims: Conventional reporting of polyps is often incomplete. We tested the Polyp Manager (PM), a new software application permitting the endoscopist to document polyps in real time during colonoscopy. We studied completeness of polyp descriptions, user-friendliness and the potential time benefit. Patients and methods: In two Dutch hospitals colonoscopies were performed with PM (as a touchscreen endoscopist-operated device or nurse-operated desktop application). Completeness of polyp descriptions was compared to a historical group with conventional reporting (CRH). Prospectively, we compared user-friendliness (VAS-scores) and time benefit of the endoscopist-operated PM to conventional reporting (CR) in one hospital. Duration of colonoscopy and time needed to report polyps and provide a pathology request were measured. Provided that using PM does not prolong colonoscopy, the sum of the latter two was considered as a potential time-benefit if the PM were fully integrated into a digital reporting system. Results: A total of 144 regular colonoscopies were included in the study. Both groups were comparable with regard to patient characteristics, duration of colonoscopy and number of polyps. Using the PM did reduce incomplete documentation of the following items in CRH-reports: location (96 % vs 82 %, P = 0.01), size (95 % vs 89 %, P = 0.03), aspect (71 % vs 36 %, P < 0.001) and completeness of removal (61 % vs 37 %, P < 0.001). In the prospective study 23 PM-colonoscopies where compared to 28 CR-colonoscopies. VAS-scores were significantly higher in the endoscopist-operated PM group. Time to report was 01:27 ± 01:43 minutes (median + interquartile range) in the entire group (PM as CR), reflecting potential time benefit per colonoscopy. Conclusions: The PM is a user-friendly tool that seems to improve completeness of polyp reporting. Once integrated with digital reporting systems, it is probably time saving as well.

Diarrhoea caused by a stenosis of the coeliac artery: suggestive for mesenteric steal

Désirée van Noord; Peter Mensink; Pieter Ter Borg; Peter M. T. Pattynama; Hence J.M. Verhagen; Ernst J. Kuipers

The classical triad of postprandial pain, weight loss and an abdominal bruit is thought to be the most common presentation of chronic gastrointestinal ischaemia. We describe a patient with severe diarrhoea as an uncommon presenting symptom of small bowel ischaemia, suggesting a mesenteric steal phenomenon due to a significant atherosclerotic coeliac artery stenosis. The stenosis and concomitant steal effect was successfully treated by stent placement. The latter is supported by the patient’s uneventful course after stent placement. This case illustrates that chronic gastrointestinal ischaemia has to be considered in patients with otherwise unexplained diarrhoea.
