ABSTRACT

BACKGROUND: Recognition of submucosal invasive colorectal cancer (T1 CRC) is difficult, with sensitivities of 35 %-60 % in Western countries. We evaluated the real-life effects of training in the OPTICAL model, a recently developed structured and validated prediction model, in Dutch community hospitals. METHODS: In this prospective multicenter study (OPTICAL II), 383 endoscopists from 40 hospitals were invited to follow an e-learning program on the OPTICAL model, to increase sensitivity in detecting T1 CRC in nonpedunculated polyps. Real-life recognition of T1 CRC was then evaluated in 25 hospitals. Endoscopic and pathologic reports of T1 CRCs detected during the next year were collected retrospectively, with endoscopists unaware of this evaluation. Sensitivity for T1 CRC recognition, R0 resection rate, and treatment modality were compared for trained vs. untrained endoscopists. RESULTS: 1 year after e-learning, 528 nonpedunculated T1 CRCs were recorded for endoscopies performed by 251 endoscopists (118 [47 %] trained). Median T1 CRC size was 20 mm. Lesions were mainly located in the distal colorectum (66 %). Trained endoscopists recognized T1 CRCs more frequently than untrained endoscopists (sensitivity 74 % vs. 62 %; mixed model analysis odds ratio [OR] 2.90, 95 %CI 1.54-5.45). R0 resection rate was higher for T1 CRCs detected by trained endoscopists (69 % vs. 56 %; OR 1.73, 95 %CI 1.03-2.91). CONCLUSION: Training in optical recognition of T1 CRCs in community hospitals was associated with increased recognition of T1 CRCs, leading to higher en bloc and R0 resection rates. This may be an important step toward more organ-preserving strategies.

ABSTRACT

OBJECTIVE: Endoscopic mucosal resection (EMR) is the preferred treatment for non-invasive large (≥20 mm) non-pedunculated colorectal polyps (LNPCPs) but is associated with an early recurrence rate of up to 30%. We evaluated whether standardised EMR training could reduce recurrence rates in Dutch community hospitals. DESIGN: In this multicentre cluster randomised trial, 59 endoscopists from 30 hospitals were randomly assigned to the intervention group (e-learning and 2-day training including hands-on session) or control group. From April 2019 to August 2021, all consecutive EMR-treated LNPCPs were included. Primary endpoint was recurrence rate after 6 months. RESULTS: A total of 1412 LNPCPs were included; 699 in the intervention group and 713 in the control group (median size 30 mm vs 30 mm, 45% vs 52% size, morphology, site and access (SMSA) score IV, 64% vs 64% proximal location). Recurrence rates were lower in the intervention group compared with controls (13% vs 25%, OR 0.43; 95% CI 0.23 to 0.78; p=0.005) with similar complication rates (8% vs 9%, OR 0.93; 95% CI 0.64 to 1.36; p=0.720). Recurrences were more often unifocal in the intervention group (92% vs 76%; p=0.006). In sensitivity analysis, the benefit of the intervention on recurrence rate was only observed in the 20-40 mm LNPCPs (5% vs 20% in 20-29 mm, p=0.001; 10% vs 21% in 30-39 mm, p=0.013) but less evident in ≥40 mm LNPCPs (24% vs 31%; p=0.151). In a post hoc analysis, the training effect was maintained in the study group, while in the control group the recurrence rate remained high. CONCLUSION: A compact standardised EMR training for LNPCPs significantly reduced recurrences in community hospitals. This strongly argues for a national dedicated training programme for endoscopists performing EMR of ≥20 mm LNPCPs. Interestingly, in sensitivity analysis, this benefit was limited for LNPCPs ≥40 mm.

ABSTRACT

BACKGROUND AND AIMS: While some articles describe outcome of pregnancy in autoimmune hepatitis (AIH), there are less data evaluating influence of AIH control on maternal and perinatal outcomes. This study analysed outcomes of pregnancy and related possible risk factors in AIH. METHOD: A retrospective multicentre cohort study on pregnancy in AIH was performed in 11 hospitals in the Netherlands. Maternal and neonatal outcomes were collected from records and completed by interview. Risk factors-including incomplete response, relapse and cirrhosis-for adverse outcomes were identified using logistic regression analysis. RESULTS: Ninety-seven pregnancies in 50 women resulted in 70 deliveries (72%) with a live birth rate of 98.5%. AIH relapse occurred in 6% during pregnancy, and in 27% of post-partum episodes. Absence of complete biochemical response at conception was identified as risk factor for the occurrence of gestational and post-partum relapses. Relapse of AIH in the year before conception was a risk factor for the occurrence of both gestational relapses and post-partum relapses. No complete biochemical response increased the risk for hypertensive disorders during pregnancy and intrahepatic cholestasis of pregnancy (ICP). Cirrhosis was found to be a risk factor for miscarriages, but not for other outcomes. CONCLUSION: Pregnancy in AIH is related to an increased incidence of maternal and fetal/neonatal complications; in most cases, outcome is good. Incomplete biochemical response at conception or relapse in the year before conception are risk factors for gestational and post-partum relapses, for hypertensive disorders and for ICP. Cirrhosis was a risk factor for miscarriages.

ABSTRACT

UNLABELLED: Pruritus is a seriously disabling symptom accompanying many cholestatic liver disorders. Recent experimental evidence implicated the lysophospholipase, autotaxin (ATX), and its product, lysophosphatidic acid (LPA), as potential mediators of cholestatic pruritus. In this study, we highlight that increased serum ATX levels are specific for pruritus of cholestasis, but not pruritus of uremia, Hodgkin's disease, or atopic dermatitis. Treatment of patients with cholestasis with the bile salt sequestrant, colesevelam, but not placebo, effectively reduced total serum bile salts and fibroblast growth factor 19 levels, but only marginally altered pruritus intensity and ATX activity. Rifampicin (RMP) significantly reduced itch intensity and ATX activity in patients with pruritus not responding to bile salt sequestrants. In vitro, RMP inhibited ATX expression in human HepG2 hepatoma cells and hepatoma cells overexpressing the pregnane X receptor (PXR), but not in hepatoma cells in which PXR was knocked down. Treatment of severe, refractory pruritus by the molecular adsorbents recirculation system or nasobiliary drainage improved itch intensity, which, again, correlated with the reduction of ATX levels. Upon reoccurrence of pruritus, ATX activity returned to pretreatment values. CONCLUSION: Serum ATX activity is specifically increased in patients with cholestatic, but not other forms of, systemic pruritus and closely correlates with the effectiveness of therapeutic interventions. The beneficial antipruritic action of RMP may be explained, at least partly, by the PXR-dependent transcriptional inhibition of ATX expression. Thus, ATX likely represents a novel therapeutic target for pruritus of cholestasis.

ABSTRACT

BACKGROUND: A decrease in the need for liver transplantations (LTX) in Primary Biliary Cirrhosis (PBC), possibly related to treatment with ursodeoxycholic acid (UDCA), has been reported in the USA and UK. The aim of this study was to assess LTX requirements in PBC over the past 20 years in the Netherlands. METHODS: Analysis of PBC transplant data of the Dutch Organ Transplant Registry during the period 1988-2008, including both absolute and proportional numbers. The indication for LTX was categorized as liver failure, hepatocellular carcinoma or poor quality of life (severe fatigue or pruritus). Data were analysed for two decades: 1.1.1988-31.12.1997 (1(st)) and 1.1.1998-31.12.2007 (2(nd)). The severity of disease was quantified using MELD scores. To fit lines which show trends over time we applied a linear regression model. RESULTS: A total of 110 patients (87% women) was placed on the waiting list. 105 patients were transplanted (1(st): 61, 2(nd): 44), 5 (5%) died while listed. The absolute annual number of LTX for PBC slightly decreased during the 20 year period, the proportional number decreased significantly. At the time of LTX the mean age was 53.6 yrs. (1(st): 53.4, 2(nd): 53.8), the mean MELD score 13.9 (1(st):14.5, 2(nd):13.0). The median interval from diagnosis to LTX was 90.5 months (1(st):86.5, 2(nd): 93.5). 69% of patients was treated with UDCA (1(st) 38%, 2(nd) 82%). CONCLUSIONS: Over the past 20 years the absolute number of LTX for PBC in the Netherlands showed a tendency to decrease whereas the proportional decrease was significant. There was a trend over time toward earlier transplantation.

ABSTRACT

We have developed a method to longitudinally classify subjects into two or more prognostic groups using longitudinally observed values of markers related to the prognosis. We assume the availability of a training data set where the subjects' allocation into the prognostic group is known. The proposed method proceeds in two steps as described earlier in the literature. First, multivariate linear mixed models are fitted in each prognostic group from the training data set to model the dependence of markers on time and on possibly other covariates. Second, fitted mixed models are used to develop a discrimination rule for future subjects. Our method improves upon existing approaches by relaxing the normality assumption of random effects in the underlying mixed models. Namely, we assume a heteroscedastic multivariate normal mixture for random effects. Inference is performed in the Bayesian framework using the Markov chain Monte Carlo methodology. Software has been written for the proposed method and it is freely available. The methodology is applied to data from the Dutch Primary Biliary Cirrhosis Study.

ABSTRACT

UNLABELLED: Colesevelam is an anion-exchange resin with a 7-fold higher bile acid-binding capacity and fewer side effects than cholestyramine, the current first-line treatment option for cholestatic pruritus. The aim of this trial was to compare the effects of colesevelam and a placebo in patients with cholestatic pruritus. In a randomized, double-blind, investigator-initiated, multicenter trial, patients with cholestatic pruritus, both treatment-naive and previously treated, received 1875 mg of colesevelam or an identical placebo twice daily for 3 weeks. The effect on pruritus was assessed with daily visual analogue scales, quality-of-life scores, and evaluations of cutaneous scratch lesions. The predefined primary endpoint was the proportion of patients with at least a 40% reduction in pruritus visual analogue scale scores. Thirty-eight patients were included, and 35 were evaluable: 17 took colesevelam, 18 took the placebo, 22 were female, 8 were treatment-naive, 14 had primary biliary cirrhosis, and 14 had primary sclerosing cholangitis. The mean serum bile acid levels were comparable between the groups before treatment (P = 0.74), but they were significantly different after treatment (P = 0.01) in favor of patients treated with colesevelam. Thirty-six percent of patients in the colesevelam group reached the primary endpoint versus 35% in the placebo group (P = 1.0). There were no significant differences between the groups with respect to pruritus scores, quality-of-life scores, and severity of cutaneous scratch lesions. Mild side effects occurred in one colesevelam-treated patient and four placebo-treated patients. CONCLUSION: Although colesevelam significantly decreased serum bile acid levels, this trial was unable to demonstrate that it was more effective than a placebo in alleviating the severity of pruritus of cholestasis.

ABSTRACT

BACKGROUND & AIMS: Pruritus is a common and disabling symptom in cholestatic disorders. However, its causes remain unknown. We hypothesized that potential pruritogens accumulate in the circulation of cholestatic patients and activate sensory neurons. METHODS: Cytosolic free calcium ([Ca(2+)](i)) was measured in neuronal cell lines by ratiometric fluorometry upon exposure to serum samples from pruritic patients with intrahepatic cholestasis of pregnancy (ICP), primary biliary cirrhosis (PBC), other cholestatic disorders, and pregnant, healthy, and nonpruritic disease controls. Putative [Ca(2+)](i)-inducing factors in pruritic serum were explored by analytical techniques, including quantification by high-performance liquid chromatography/mass spectroscopy. In mice, scratch activity after intradermal pruritogen injection was quantified using a magnetic device. RESULTS: Transient increases in neuronal [Ca(2+)](i) induced by pruritic PBC and ICP sera were higher than corresponding controls. Lysophosphatidic acid (LPA) could be identified as a major [Ca(2+)](i) agonist in pruritic sera, and LPA concentrations were increased in cholestatic patients with pruritus. LPA injected intradermally into mice induced scratch responses. Autotaxin, the serum enzyme converting lysophosphatidylcholine into LPA, was markedly increased in patients with ICP versus pregnant controls (P < .0001) and cholestatic patients with versus without pruritus (P < .0001). Autotaxin activity correlated with intensity of pruritus (P < .0001), which was not the case for serum bile salts, histamine, tryptase, substance P, or mu-opioids. In patients with PBC who underwent temporary nasobiliary drainage, both itch intensity and autotaxin activity markedly decreased during drainage and returned to preexistent levels after drain removal. CONCLUSIONS: We suggest that LPA and autotaxin play a critical role in cholestatic pruritus and may serve as potential targets for future therapeutic interventions.

ABSTRACT

BACKGROUND & AIMS: Primary biliary cirrhosis (PBC) and autoimmune hepatitis (AIH) differ in clinical, laboratory, and histologic features as well as in response to therapy. A small subgroup of patients have an overlap syndrome with features of both diseases, although there is no consensus on its definition or diagnostic criteria. We evaluated the significance of the criteria used to diagnose PBC-AIH overlap syndrome. METHODS: This retrospective, single-center study included all patients diagnosed with PBC, AIH, or PBC-AIH overlap syndrome, based on the Paris criteria, since January 1990 (n = 134); patients were followed up for 9.7 +/- 3.7 years. The 3 groups were compared for their clinical, laboratory, and histologic features. Patients with overlap syndrome or PBC were graded by the revised and simplified AIH scoring systems to assess the ability of this system to identify AIH cases properly. RESULTS: The sensitivity and specificity of the Paris criteria for diagnosing the overlap syndrome were 92% and 97%, respectively. The sensitivity and specificity of the AIH scoring systems were considerably lower. Among patients with the overlap syndrome, the 10-year, transplantation-free survival rate was 92%. CONCLUSIONS: The Paris diagnostic criteria detect overlap syndrome (PBC and AIH) with high levels of sensitivity and specificity. The clinical value of the revised and simplified AIH scoring system is not as reliable. Patients with PBC-AIH overlap syndrome have a 92% rate of 10-year, transplantation-free survival.

ABSTRACT

BACKGROUND: The reported incidence of hepatocellular carcinoma (HCC) among patients with primary biliary cirrhosis (PBC) varies from 0.7-3.8%, whereas in cirrhotic patients the risk is considerably higher. Age, male sex, cirrhosis, and portal hypertension are reported risk factors. It has been suggested that ursodeoxycholic acid (UDCA) may protect against HCC. We aimed to define risk factors for the development of HCC at the time of PBC diagnosis and to identify, among patients treated with UDCA for a long term, a subgroup that could benefit from screening. METHODS: Prospective multicenter cohort study of patients with established PBC treated with 13-15 mg/kg/day UDCA. Age, sex, antimitochondrial antibodies, bilirubin, albumin, alkaline phosphatase, alanine aminotransferase, aspartate amino transferase, cirrhosis, portal hypertension, Mayo Risk Score, prognostic class (based on bilirubin and albumin levels), and response to UDCA (normalization of bilirubin and/or albumin levels) were analyzed as potential risk factors in Cox regression analysis. RESULTS: Three hundred and seventy-five patients were included, median follow-up was 9.7 years. HCC occurred in nine patients, corresponding with an annual incidence of 0.2%. The factor significantly associated with the development of HCC was the response to UDCA (P<0.001). The risk for HCC was highest in the group of nonresponders to UDCA: the 10 years incidence of HCC was 9% and the 15 years incidence was 20%. The number needed to screen in this subgroup was 11. CONCLUSION: In UDCA treated PBC patients the risk of HCC is relatively low. The main risk factor for HCC in this study was the absence of biochemical response to UDCA after 1-year treatment.

ABSTRACT

BACKGROUND: The aim was to evaluate overall and disease-specific mortality in a population-based inflammatory bowel disease (IBD) cohort in the Netherlands, as well as risk factors for mortality. METHODS: IBD patients diagnosed between 1 January 1991 and 1 January 2003 were included. Standardized mortality ratios (SMRs) were calculated overall and with regard to causes of death, gender, as well as age, phenotype, smoking status at diagnosis, and medication use. RESULTS: At the censoring date, 72 out of 1187 patients had died (21 Crohn's disease [CD], 47 ulcerative colitis [UC], and 4 indeterminate colitis [IC] patients). The SMR (95% confidence interval [CI]) was 1.1 (0.7-1.6) for CD, 0.9 (0.7-1.2) for UC and 0.7 (0.2-1.7) for IC. Disease-specific mortality risk was significantly increased for gastrointestinal (GI) causes of death both in CD (SMR 7.5, 95% CI: 2.8-16.4) and UC (SMR 3.4, 95% CI: 1.4-7.0); in CD patients, especially in patients <40 years of age at diagnosis. For UC, an increased SMR was noted in female patients and in patients <19 years and >80 years at diagnosis. In contrast, UC patients had a decreased mortality risk from cancer (SMR 0.5, 95% CI; 0.2-0.9). CONCLUSIONS: In this population-based IBD study, mortality in CD, UC, and IC was comparable to the background population. The increased mortality risk for GI causes might reflect complicated disease course, with young and elderly patients at diagnosis needing intensive follow-up. Caution in interpreting the finding on mortality risk from cancer is needed as follow-up was probably to short to observe IBD-related cancers.

ABSTRACT

In the Netherlands there are probably several thousands of patients with primary biliary cirrhosis (PBC), a slowly progressive liver disease mainly affecting middle-aged women. PBC has characteristics of an autoimmune disease but its precise aetiology remains unknown. Fatigue and pruritus are the main symptoms but patients may also be asymptomatic. The diagnosis can be established through the presence of cholestatic liver test abnormalities, antimitochondrial antibodies and diagnostic or compatible findings upon liver biopsy. Currently most patients are diagnosed with early disease. When treated with ursodeoxycholic acid these patients have a normal prognosis.

ABSTRACT

BACKGROUND & AIMS: Ursodeoxycholic acid (UDCA) improves laboratory liver test results in patients with primary biliary cirrhosis (PBC). Few studies have assessed the prognostic significance of biochemical data collected following UDCA treatment. We performed a prospective multicenter study of patients with PBC treated with UDCA to compare prognosis with biochemical response. METHODS: PBC was classified as early (pretreatment bilirubin and albumin levels normal), moderately advanced (one level abnormal), or advanced (both levels abnormal). Biochemical response was defined as proposed by Pares (decrease in alkaline phosphatase [ALP] level>40% of baseline level or normal level), Corpechot (ALP level<3-fold the upper limit of normal [ULN], aspartate aminotransferase level<2-fold the ULN, bilirubin level<1-fold the ULN), and our group (Rotterdam; normalization of abnormal bilirubin and/or albumin levels). RESULTS: The study included 375 patients, and median follow-up time was 9.7 (range, 1.0-17.3) years. The prognosis for early PBC was comparable with that of the Dutch population and better than predicted by the Mayo risk score. Survival of responders was better than that of nonresponders, according to Corpechot and Rotterdam criteria (P<.001). Prognosis of early PBC was comparable for responders and nonresponders; prognosis of responders was significantly better in those with (moderately) advanced disease. CONCLUSIONS: Prognosis for UDCA-treated patients with early PBC is comparable to that of the general population. Survival of those with advanced PBC with biochemical response to UDCA is significantly better than for nonresponders. Thus, UDCA may be of benefit irrespective of the stage of disease. Prognostic information, based on bilirubin and albumin levels, is superior to that provided by ALP levels.
