Incidence and prevalence of primary biliary cholangitis in the Netherlands - A nationwide cohort study.

Background & Aims: Although primary biliary cholangitis (PBC) is considered a rare disorder, accurate determination of its incidence and prevalence remains challenging due to limited comprehensive population-based registries. We aimed to assess the incidence and prevalence of PBC in the Netherlands over time through the nationwide Dutch PBC Cohort Study (DPCS).

Methods: DPCS retrospectively included every identifiable patient with PBC in the Netherlands from 1990 onwards in all 71 Dutch hospitals.

An open-label randomised-controlled trial of azathioprine vs. mycophenolate mofetil for the induction of remission in treatment-naive autoimmune hepatitis.

Background & Aims: Patients with autoimmune hepatitis (AIH) almost invariably require lifelong immunosuppressive treatment. There is genuine concern about the efficacy and tolerability of the current standard combination therapy of prednisolone and azathioprine. Mycophenolate mofetil (MMF) has emerged as an alternative option.

Assessing the efficacy and safety of mycophenolate mofetil versus azathioprine in patients with autoimmune hepatitis (CAMARO trial): study protocol for a randomised controlled trial.

Background: Currently, the standard therapy for autoimmune hepatitis (AIH) consists of a combination of prednisolone and azathioprine. However, 15% of patients are intolerant to azathioprine which necessitates cessation of azathioprine or changes in therapy. In addition, not all patients achieve complete biochemical response (CR).

Aggressive fluid hydration plus non-steroidal anti-inflammatory drugs versus non-steroidal anti-inflammatory drugs alone for post-endoscopic retrograde cholangiopancreatography pancreatitis (FLUYT): a multicentre, open-label, randomised, controlled trial.

Background: Pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP). Prophylactic rectal administration of non-steroidal anti-inflammatory drugs (NSAIDs) is considered as standard of care to reduce the risk of post-ERCP pancreatitis. It has been suggested that aggressive hydration might further reduce this risk.

High discontinuation rate of azathioprine in autoimmune hepatitis, independent of time of treatment initiation.

Background: Guidelines regarding treatment for autoimmune hepatitis (AIH) favour two strategies for azathioprine (AZA) introduction: concurrent with steroids at induction or delayed by 2-4 weeks. The safety and efficacy of both strategies have been unexplored.

Methods: We established a cohort of 900 AIH patients from 12 centres in 7 European countries.

Rapid Response to Treatment of Autoimmune Hepatitis Associated With Remission at 6 and 12 Months.

Background & Aims: Changes in serum levels of transaminases immediately after initiation of treatment for autoimmune hepatitis (AIH) might be associated with biochemical markers of remission and liver-related events. We assessed the outcomes of patients with vs without rapid response to treatment of AIH in a large international cohort.

Methods: We performed a retrospective cohort study, collecting data from 2 independent cohorts of adults with AIH from 12 centers in 7 countries in Europe.

Predniso(lo)ne Dosage and Chance of Remission in Patients With Autoimmune Hepatitis.

Background & Aims: Patients with autoimmune hepatitis (AIH) commonly receive induction therapy with predniso(lo)ne followed by maintenance therapy with azathioprine. European Association for Study of the Liver clinical practice guidelines advise a predniso(lo)ne dose range of 0.50-1 mg/kg/day, which leaves room for practice variation.

Regression of hepatocellular adenoma after bariatric surgery in severe obese patients.

Background & Aim: Obesity and metabolic syndrome are increasingly recognized as risk factors for hepatocellular adenomas (HCA). There is still sparse evidence whether weight loss or bariatric surgery could induce HCA regression in these patients. In this brief report we describe the effect of weight loss on HCA regression in severe obese patients that had undergone bariatric surgery in our centre.

Fluid hydration to prevent post-ERCP pancreatitis in average- to high-risk patients receiving prophylactic rectal NSAIDs (FLUYT trial): study protocol for a randomized controlled trial.

Background: Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is the most common complication of ERCP and may run a severe course. Evidence suggests that vigorous periprocedural hydration can prevent PEP, but studies to date have significant methodological drawbacks. Importantly, evidence for its added value in patients already receiving prophylactic rectal non-steroidal anti-inflammatory drugs (NSAIDs) is lacking and the cost-effectiveness of the approach has not been investigated.

Epidemiology and clinical characteristics of autoimmune hepatitis in the Netherlands.

Background And Aims: Epidemiological data on autoimmune hepatitis (AIH) are scarce. In this study, we determined the clinical and epidemiological characteristics of AIH patients in the Netherlands (16.7 million inhabitants).

Rhabdomyolysis in a hepatitis C virus infected patient treated with telaprevir and simvastatin.

A 46-year old man with a chronic hepatitis C virus infection received triple therapy with ribavirin, pegylated interferon and telaprevir. The patient also received simvastatin. One month after starting the antiviral therapy, the patient was admitted to the hospital because he developed rhabdomyolysis.

[Gastrointestinal tuberculosis: a deceptive disease].

Incidence of tuberculosis has increased in the Netherlands in recent years, especially among immigrants. Nearly half of all patients with tuberculosis have extrapulmonary disease; in 5% of these patients it is localized in the gastrointestinal tract. Despite the low incidence of gastrointestinal tuberculosis we recently established this diagnosis in three of our patients, who demonstrated tuberculosis within the oesophagus, colon and pancreas, respectively.

[Hepatitis B; sometimes co-infection with hepatitis D].

Background: The Hepatitis delta virus (HDV) is a defect RNA virus that requires the presence of the hepatitis B virus (HBV) for cellular infection. Worldwide, 350 million people are infected with HBV; 5% of these are superinfected with HDV. A chronic superinfection with HDV has a higher morbidity and mortality rate.

[Vomiting, abdominal pain and weight loss with an acquired anatomical cause: superior mesenteric artery syndrome].

Superior mesenteric artery syndrome (SMAS) is a rare and acquired anatomical condition characterized by vomiting, abdominal distension, weight loss and postprandial distress due to compression of the transverse portion of the duodenum between the superior mesenteric artery (SMA) and aorta, which causes duodenal outflow problems. We report a case series of three patients with SMAS. Diagnosis of the syndrome was made by augmenting a high degree of suspicion with repeat gastroscopies, CT scans and hypotonic duodenal contrast series showing compression of the horizontal part of the duodenum located between the vessels specified above.

International, multicenter, randomized, controlled study comparing dynamically individualized versus standard treatment in patients with chronic hepatitis C.

Background/aims: The aim of this study was to increase virologic response rates by individualized treatment according to the early virologic response.

Methods: Serum HCV-RNA was frequently quantified in patients with chronic hepatitis C (n=270) treated with peginterferon alfa-2a (180 microg/week) and ribavirin (1000-1200 mg/day). After 6 weeks patients were classified as rapid (RVR), slow (SPR), flat (FPR), or null responders (NUR) and randomized within each viral kinetic class to continue therapy either with an individualized or standard regimen.

The relation between plasma tyrosine concentration and fatigue in primary biliary cirrhosis and primary sclerosing cholangitis.

Background: In 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.
