Restrictive strategy versus usual care for cholecystectomy in patients with gallstones and abdominal pain (SECURE): a multicentre, randomised, parallel-arm, non-inferiority trial. Lancet 2019; 393:2322-2330. [PMID: 31036336 DOI: 10.1016/s0140-6736(19)30941-9] [Citation(s) in RCA: 40] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2019] [Revised: 04/01/2019] [Accepted: 04/02/2019] [Indexed: 12/11/2022]
Abstract
BACKGROUND International guidelines advise laparoscopic cholecystectomy to treat symptomatic, uncomplicated gallstones. Usual care regarding cholecystectomy is associated with practice variation and persistent post-cholecystectomy pain in 10-41% of patients. We aimed to compare the non-inferiority of a restrictive strategy with stepwise selection with usual care to assess (in)efficient use of cholecystectomy. METHODS We did a multicentre, randomised, parallel-arm, non-inferiority study in 24 academic and non-academic hospitals in the Netherlands. We enrolled patients aged 18-95 years with abdominal pain and ultrasound-proven gallstones or sludge. Patients were randomly assigned (1:1) to either usual care in which selection for cholecystectomy was left to the discretion of the surgeon, or a restrictive strategy with stepwise selection for cholecystectomy. For the restrictive strategy, cholecystectomy was advised for patients who fulfilled all five pre-specified criteria of the triage instrument: 1) severe pain attacks, 2) pain lasting 15-30 min or longer, 3) pain located in epigastrium or right upper quadrant, 4) pain radiating to the back, and 5) a positive pain response to simple analgesics. Randomisation was done with an online program, implemented into a web-based application using blocks of variable sizes, and stratified for centre (academic versus non-academic and a high vs low number of patients), sex, and body-mass index. Physicians and patients were masked for study-arm allocation until after completion of the triage instrument. The primary, non-inferiority, patient-reported endpoint was the proportion of patients who were pain-free at 12 months' follow-up, analysed by intention to treat and per protocol. A 5% non-inferiority margin was chosen, based on the estimated clinically relevant difference. Safety analyses were also done in the intention-to treat population. This trial is registered at the Netherlands National Trial Register, number NTR4022. FINDINGS Between Feb 5, 2014, and April 25, 2017, we included 1067 patients for analysis: 537 assigned to usual care and 530 to the restrictive strategy. At 12 months' follow-up 298 patients (56%; 95% CI, 52·0-60·4) were pain-free in the restrictive strategy group, compared with 321 patients (60%, 55·6-63·8) in usual care. Non-inferiority was not shown (difference 3·6%; one-sided 95% lower CI -8·6%; pnon-inferiority=0·316). According to a secondary endpoint analysis, the restrictive strategy resulted in significantly fewer cholecystectomies than usual care (358 [68%] of 529 vs 404 [75%] of 536; p=0·01). There were no between-group differences in trial-related gallstone complications (40 patients [8%] of 529 in usual care vs 38 [7%] of 536 in restrictive strategy; p=0·16) and surgical complications (74 [21%] of 358 vs 88 [22%] of 404, p=0·77), or in non-trial-related serious adverse events (27 [5%] of 529 vs 29 [5%] of 526). INTERPRETATION Suboptimal pain reduction in patients with gallstones and abdominal pain was noted with both usual care and following a restrictive strategy for selection for cholecystectomy. However, the restrictive strategy was associated with fewer cholecystectomies. The findings should encourage physicians involved in the care of patients with gallstones to rethink cholecystectomy, and to be more careful in advising a surgical approach in patients with gallstones and abdominal symptoms.

A Novel Automatic Digital Algorithm that Accurately Quantifies Steatosis in NAFLD on Histopathological Whole-Slide Images. CYTOMETRY PART B-CLINICAL CYTOMETRY 2019; 96:521-528. [PMID: 31173462 PMCID: PMC6899563 DOI: 10.1002/cyto.b.21790] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/18/2018] [Revised: 04/21/2019] [Accepted: 05/17/2019] [Indexed: 12/14/2022]
Abstract
Background Accurate assessment of hepatic steatosis is a key to grade disease severity in non‐alcoholic fatty liver disease (NAFLD). Methods We developed a digital automated quantification of steatosis on whole‐slide images (WSIs) of liver tissue and performed a validation study. Hematoxylin–eosin stained liver tissue slides were digitally scanned, and steatotic areas were manually annotated. We identified thresholds for size and roundness parameters by logistic regression to discriminate steatosis from surrounding liver tissue. The resulting algorithm produces a steatosis proportionate area (SPA; ratio of steatotic area to total tissue area described as percentage). The software can be implemented as a Java plug‐in in FIJI, in which digital WSI can be processed automatically using the Pathomation extension. Results We obtained liver tissue specimens from 61 NAFLD patients and 18 controls. The area under the curve of correctly classified steatosis by the algorithm was 0.970 (95% CI 0.968–0.973), P < 0.001. Accuracy of the algorithm was 91.9%, with a classification error of 8.1%. SPA correlated significantly with steatosis grade (Rs = 0.845, CI: 0.749–0.902, P < 0.001) and increased significantly with each individual steatosis grade, except between Grade 2 and 3. Conclusions We have developed a novel digital analysis algorithm that accurately quantifies steatosis on WSIs of liver tissue. This algorithm can be incorporated when quantification of steatosis is warranted, such as in clinical trials studying efficacy of new therapeutic interventions in NAFLD. © 2019 The Authors.

Eur Radiol 2019; 29:3062-3068. [PMID: 30542749 PMCID: PMC6510865 DOI: 10.1007/s00330-018-5851-y] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2018] [Revised: 09/29/2018] [Accepted: 10/23/2018] [Indexed: 12/13/2022]
Abstract
OBJECTIVE To assess whether quantitative assessment of symptom reduction is a better outcome parameter than cyst volume reduction for treatment success in patients treated by aspiration sclerotherapy. METHODS We included patients with symptomatic, large (> 5 cm), hepatic cysts from a randomized controlled trial (NCT02048319). At baseline and 6 months after treatment, symptoms were assessed with the polycystic liver disease questionnaire (PLD-Q) and we measured cyst volume using ultrasonography. Patient-reported change in health was assessed on a 5-point Likert scale (much worse to much better) after 6 months. We tested whether PLD-Q scores and cyst volumes changed after aspiration sclerotherapy (responsiveness). Changes in PLD-Q scores and cyst volume were compared with change in health as a measure of treatment success (discriminative ability). As secondary analysis, we compared baseline characteristics between responders (improved) and non-responders (not improved). RESULTS We included 32 patients. Six months after treatment, 23 patients (72%) improved. Both PLD-Q score and cyst volume significantly decreased (median 38 to 18 points, p < 0.001, and 479 to 68 mL, p < 0.001). Larger improvement in PLD-Q score was associated with a positive change in health (p = 0.001), while larger proportional reduction in cyst volume was not significantly associated with health improvement after treatment (p = 0.136). Responders had larger baseline cyst volumes compared to non-responders (median 624 mL [IQR 343-1023] vs. 322 mL [IQR 157-423] p = 0.008). CONCLUSION Cyst diameter reduction does not reflect treatment success in aspiration sclerotherapy from patients' perspective, while symptoms measured with the PLD-Q can be used as a reliable outcome measure. KEY POINTS • Cyst diameter reduction poorly reflects treatment success in aspiration sclerotherapy. • Symptoms measured by the polycystic liver disease questionnaire (PLD-Q) is a better outcome measure than cyst volume reduction for treatment success after aspiration sclerotherapy. • Particularly patients with larger cysts (≥ 529 mL) benefit from aspiration sclerotherapy.

Abstract
We identified a homozygous missense mutation in the gene encoding NAD synthesizing enzyme NMNAT2 in two siblings with childhood onset polyneuropathy with erythromelalgia. No additional homozygotes for this rare allele, which leads to amino acid substitution T94M, were present among the unaffected relatives tested or in the 60,000 exomes of the ExAC database. For axons to survive, axonal NMNAT2 activity has to be maintained above a threshold level but the T94M mutation confers a partial loss of function both in the ability of NMNAT2 to support axon survival and in its enzymatic properties. Electrophysiological tests and histological analysis of sural nerve biopsies in the patients were consistent with loss of distal sensory and motor axons. Thus, it is likely that NMNAT2 mutation causes this pain and axon loss phenotype making this the first disorder associated with mutation of a key regulator of Wallerian-like axon degeneration in humans. This supports indications from numerous animal studies that the Wallerian degeneration pathway is important in human disease and raises important questions about which other human phenotypes could be linked to this gene.

Abstract
Chronic hepatitis C virus (HCV) infection is a global public health issue, which is associated with high rates of morbidity and mortality. The development of direct acting antivirals (DAAs) has transformed treatment: they offer us highly-effective therapy with superior tolerability compared to interferon-containing regimens. In 2016, the World Health Organization (WHO) therefore adopted several ambitious viral hepatitis elimination targets, aiming for a 90% reduction in new infections and a 65% reduction in mortality by 2030. The ultimate goal is to eliminate HCV completely. It is reasonable that these goals may be achieved in the Netherlands due to the low prevalence of chronic HCV, the availability of DAAs, and excellent healthcare infrastructure. This paper describes a national effort to curtail the HCV epidemic in the Netherlands through an HCV retrieval and linkage to care project (CELINE: Hepatitis C Elimination in the Netherlands).

Abstract
BACKGROUND & AIMS There have been few reproducible studies of mortality in patients with autoimmune hepatitis (AIH) and its variants. We calculated mortality in a large national cohort of patients with AIH, with vs without cirrhosis, in the Netherlands. METHODS We collected data from 449 patients with established AIH (77% female), from 6 academic and 10 non-academic hospitals in the Netherlands. We identified 29 patients with AIH and primary biliary cholangitis and 35 patients with AIH and primary sclerosing cholangitis (AIH-PSC). Mortality and liver transplantation data were assessed from August 1, 2006 through July 31, 2016. Standardized mortality ratios (SMR) were calculated using age-, sex-, and calendar year-matched mortality for the general Dutch population. RESULTS During the 10-year follow-up period, 60 patients (13%) died (mean age, 71 years; range, 33-94 years). Twenty-six causes of death were liver related (43%), whereas the others could not be attributed to liver disease. Patients with AIH and cirrhosis had significantly higher mortality than the general population (SMR, 1.9; 95% CI, 1.2-3.4), whereas patients without cirrhosis did not (SMR, 1.2; 95% CI, 0.8-1.8). Patients with AIH-PSC had the largest increase in mortality, compared to the general population (SMR, 4.7; 95% CI, 1.5-14.6), of all groups analyzed. Mortality in patients with AIH and primary biliary cholangitis was not greater than the general population. Four or more relapses per decade or not achieving remission was associated with an increase in liver-related death or liver transplantation. Nine patients underwent liver transplantation; 2 died from non-liver related causes. Four of 9 patients on the waitlist for transplantation died before receiving a donated liver. CONCLUSION In an analysis of data from a large national cohort of patients with AIH, we found increased mortality of patients with cirrhosis, but not of patients without cirrhosis, compared to the general Dutch population. Survival was significantly reduced in patients with AIH and features of concurrent PSC.

Abstract
Background The duodenal-jejunal bypass liner (DJBL) is an endoscopic device designed to induce weight loss and improve glycemic control. The liner is licensed for a maximum implant duration of 12 months. It might be hypothesized that extension of the dwelling time results in added value. The goals of our study were to determine weight change, change in glycemic control, and safety in patients with an intended 24 months of DJBL dwelling time. Methods Patients were initially selected for a 12-month implantation period. When no physical complaints or adverse events (AEs) occurred, motivated patients who responded well were selected for extension of dwelling time to 24 months. Patients underwent a control endoscopy 12 months after implantation and visited the out-patient clinic every 3 months up to explantation. Patients agreed to remove the DJBL when complaints or AEs occurred that could not be treated conservatively. Results Implantation was extended in 44 patients, and 24 (55%) patients completed the full 24 months. Twenty patients required early removal due to AEs. During dwelling time, body weight decreased significantly (15.9 kg; TBWL 14.6%). HbA1c decreased non-significantly (4.9 mmol/mol). The number of insulin users and daily dose of insulin both decreased significantly. At 24 months after removal, glycemic control had worsened, while body weight was still significantly lower compared to baseline. In total, 68% of the patients experienced at least one AE. Two patients developed a hepatic abscess. Conclusions DJBL treatment results in significant weight loss and improves glycemic control during implantation. The largest beneficial effects occur during the first 9–12 months after implantation. Extension of dwelling time to 24 months results only in stabilization of body weight and glycemic control. After explantation, weight improvements are maintained, but glycemic control worsens. As the cumulative risk of AEs increases with time, a maximal dwelling time of 12 months is advisable.

Abstract
BACKGROUND Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease that results in substantial morbidity and mortality with many unanswered clinical and research questions. Improved understanding of disease pathogenesis, including the extra-hepatic manifestations of AIH, may allow targeted treatments with greater efficacy and fewer associated adverse events. AIM To identify the spectrum of unanswered clinical and research questions facing care providers in the management of patients with autoimmune hepatitis (AIH). METHODS The International Autoimmune Hepatitis Group initiated a series of research workshops to start to address these questions. Key issues were discussed in small group sessions with collation of all discussions to be summarised in this manuscript. RESULTS Key issues were identified as: the need for better understanding of disease pathogenesis, standardisation of the methods and assays used to evaluate autoantibodies in AIH, refinement of the histopathological criteria for "typical" or "compatible" AIH, focus on the interaction with non-alcohol related fatty liver disease, how to treat acute severe AIH, better assessment of quality of life in adults and paediatrics, standardising use of standard, third-line and experimental therapies in AIH and search for biomarkers early in the disease course that predict outcome. CONCLUSION This workshop has outlined the key unanswered clinical and research questions to help to define the research agenda in AIH.

Abstract
BACKGROUND & AIMS Polycystic liver disease (PLD) occurs in two genetic disorders, autosomal-dominant polycystic kidney disease (ADPKD) and autosomal-dominant polycystic liver disease (ADPLD). The aim of this study is to compare disease severity between ADPKD and ADPLD by determining the association between diagnosis and height-adjusted total liver volume (hTLV). METHODS We performed a cross-sectional analysis with hTLV as endpoint. Patients were identified from the International PLD Registry (>10 liver cysts) and included in our analysis when PLD diagnosis was made prior to September 2017, hTLV was available before volume-reducing therapy (measured on computed tomography or magnetic resonance imaging) and when patients were tertiary referred. Data from the registry were retrieved for age, diagnosis (ADPKD or ADPLD), gender, height and hTLV. RESULTS A total of 360 patients (ADPKD n = 241; ADPLD n = 119) met our inclusion criteria. Female ADPKD patients had larger hTLV compared with ADPLD (P = 0.008). In a multivariate regression analysis, ADPKD and lower age at index CT were independently associated with larger hTLV in females, whereas in males a higher age was associated with larger hTLV. Young females (≤51 years) had larger liver volumes compared with older females (>51 years) in ADPKD. CONCLUSION Aetiology is presented as a new risk factor associated with PLD severity. Young females with ADPKD represent a subgroup of PLD patients with the most severe phenotype expressed in hTLV.

Abstract
BACKGROUND Polyethylene glycol (PEG) bowel preparations are widely used for precolonoscopy bowel cleansing. This phase 3 trial assessed the efficacy, safety, and tolerability of the novel 1 L PEG-based NER1006 vs. sodium picosulfate plus magnesium citrate (SP + MC) in day-before dosing. METHODS Patients requiring colonoscopy were randomized (1 : 1) to receive NER1006 or SP + MC. Cleansing was assessed on the Harefield Cleansing Scale (HCS) and Boston Bowel Preparation Scale (BBPS) using central readers. Two primary end points were assessed: overall colon cleansing success and high-quality cleansing of the right colon. Intention-to-treat (modified full analysis set [mFAS]) and per protocol (PP) analyses were performed. RESULTS Of 515 patients, efficacy was analyzed in 501 (NER1006, n = 250; SP + MC, n = 251) and 379 patients (NER1006, n = 172; SP + MC, n = 207) in the mFAS and PP analyses, respectively. Non-inferiority of NER1006 vs. SP + MC was established in the mFAS for both overall cleansing (62.0 % vs. 53.8 %; P = 0.04) and high-quality cleansing in the right colon (4.4 % vs. 1.2 %; P = 0.03). Superiority of NER1006 was demonstrated using HCS in the PP set for overall cleansing success (68.0 % vs. 57.5 %; P = 0.02) and right colon high-quality cleansing (5.2 % vs. 1.0 %; P = 0.02) and using BBPS in the mFAS for overall cleansing success (58.4 % vs. 45.8 %; P = 0.003) and right colon high-quality cleansing (4.0 % vs. 0.8 %; P = 0.02). Mean segmental scores for 4/5 segments were higher with NER1006 (P ≤ 0.04). Both treatments were well tolerated, with more mild adverse events for NER1006 (17.0 % vs. 10.0 %; P = 0.03). CONCLUSIONS Colon cleansing with NER1006 vs. SP + MC was non-inferior (mFAS) and superior (PP), with acceptable safety.European Clinical Trials Database (EudraCT)2014-002186-30TRIAL REGISTRATION: Multicenter, randomized, parallel group, phase 3 study 2014-002186-30 at https://eudract.ema.europa.eu/.

Abstract
BACKGROUND The infliximab biosimilar has entered daily inflammatory bowel disease (IBD) practice. However, real-life outcomes beyond 1 year after switching are scarce. We aimed to investigate the long-term drug survival, immunogenicity, and pharmacokinetics 2 years after switching to CT-P13 in IBD patients. METHODS We performed a single-center prospective observational cohort study in all Remicade-treated IBD patients who previously switched to CT-P13. We systematically documented reasons for discontinuation, trough levels, and antidrug antibodies to infliximab (ADAs) at baseline, week 16, week 52, and week 104. Clinical and biochemical disease activity (HBI, SCCAI, CRP) and adverse events were registered. RESULTS Eighty-three patients were enrolled, 57 had Crohn's disease, 24 had ulcerative colitis, and 2 were IBD-unclassified. At week 104, 55 of 83 (66%) patients remained on CT-P13, and 3 were lost to follow-up. Reasons for discontinuation were loss of response (n = 10), adverse events (n = 8), and disease remission (n = 7). ADAs were present in 5/83 patients at baseline (before switching), in 2 patients before week 52, and no subsequent ADAs were detected until week 104. Median trough levels and clinical and biochemical disease activity at baseline, week 16, week 52 and week 104 did not significantly change. CONCLUSION In a prospective cohort with >2-year follow-up, 66% of IBD patients continued CT-P13 after switching from Remicade. Two new cases with ADAs were observed in year 1, but subsequently no immunogenicity was detected. These results are reassuring and suggest that switching to CT-P13 does not impact long-term clinical outcomes. 10.1093/ibd/izy227_video1izy227.video15802479819001.

Abstract
Importance Autosomal dominant polycystic kidney disease (ADPKD) is characterized by progressive cyst formation in both kidneys and loss of renal function, eventually leading to a need for kidney replacement therapy. There are limited therapeutic management options. Objective To examine the effect of the somatostatin analogue lanreotide on the rate of kidney function loss in patients with later-stage ADPKD. Design, Setting, and Participants An open-label randomized clinical trial with blinded end point assessment that included 309 patients with ADPKD from July 2012 to March 2015 at 4 nephrology outpatient clinics in the Netherlands. Eligible patients were 18 to 60 years of age and had an estimated glomerular filtration rate (eGFR) of 30 to 60 mL/min/1.73 m2. Follow-up of the 2.5-year trial ended in August 2017. Interventions Patients were randomized to receive either lanreotide (120 mg subcutaneously once every 4 weeks) in addition to standard care (n = 153) or standard care only (target blood pressure <140/90 mm Hg; n = 152). Main Outcomes and Measures Primary outcome was annual change in eGFR assessed as slope through eGFR values during the 2.5-year treatment phase. Secondary outcomes included change in eGFR before vs after treatment, incidence of worsening kidney function (start of dialysis or 30% decrease in eGFR), change in total kidney volume and change in quality of life (range: 1 [not bothered] to 5 [extremely bothered]). Results Among the 309 patients who were randomized (mean [SD] age, 48.4 [7.3] years; 53.4% women), 261 (85.6%) completed the trial. Annual rate of eGFR decline for the lanreotide vs the control group was -3.53 vs -3.46 mL/min/1.73 m2 per year (difference, -0.08 [95% CI, -0.71 to 0.56]; P = .81). There were no significant differences for incidence of worsening kidney function (hazard ratio, 0.87 [95% CI, 0.49 to 1.52]; P = .87), change in eGFR (-3.58 vs -3.45; difference, -0.13 mL/min/1.73 m2 per year [95% CI, -1.76 to 1.50]; P = .88), and change in quality of life (0.05 vs 0.07; difference, -0.03 units per year [95% CI, -0.13 to 0.08]; P = .67). The rate of growth in total kidney volume was lower in the lanreotide group than the control group (4.15% vs 5.56%; difference, -1.33% per year [95% CI, -2.41% to -0.24%]; P = .02). Adverse events in the lanreotide vs control group included injection site discomfort (32% vs 0.7%), injection site papule (5.9% vs 0%), loose stools (91% vs 6.6%), abdominal discomfort (79% vs 20%), and hepatic cyst infections (5.2% vs 0%). Conclusions and Relevance Among patients with later-stage autosomal dominant polycystic kidney disease, treatment with lanreotide compared with standard care did not slow the decline in kidney function over 2.5 years of follow-up. These findings do not support the use of lanreotide for treatment of later-stage autosomal dominant polycystic kidney disease. Trial Registration ClinicalTrials.gov Identifier: NCT01616927.

Abstract
BACKGROUND Cholecystectomy is the preferred treatment for symptomatic cholecystolithiasis. However, persistent pain after cholecystectomy for symptomatic cholecystolithiasis is reported in up to 40% of patients. The aim of the SECURE trial is to compare the effectiveness of usual care with a restrictive strategy using a standardized work-up with stepwise selection for cholecystectomy in patients with gallstones and abdominal complaints. The SECURE trial is designed as a multicenter, randomized, parallel-arm, non-inferiority trial in patients with abdominal symptoms and ultrasound-proven gallstones or sludge. Randomization was performed to either usual care (standard practice, according to the physician's knowledge and experience, and physician's and patient's preference) or a restrictive standardized strategy: treated with interval evaluation and stepwise selection for laparoscopic cholecystectomy based on fulfilment of pre-specified criteria. This article presents in detail the statistical analysis plan (SAP) of this trial and was submitted before outcomes were available to the investigators. RESULTS The primary end point of this trial is defined as the proportion of patients being pain-free at 12 months' follow-up. Pain will be assessed with the Izbicki Pain Score. Secondary endpoints will be the proportion of patients with complications due to gallstones or cholecystectomy, quality of life, the association between the patients' symptoms and treatment, work performance, and cost-effectiveness. DISCUSSION The data from the SECURE trial will provide evidence whether or not a restrictive strategy in patients with symptomatic cholecystolithiasis is associated with similar patient reported outcomes and a reduction in the number of cholecystectomies compared to usual care. The data from this trial will be analyzed according to this pre-specified SAP. TRIAL REGISTRATION The Netherlands National Trial Register NTR4022 . Registered on 5 June 2013.

Abstract
BACKGROUND Laparoscopic fenestration is one of the treatment options for symptomatic hepatic cysts, either solitary or in context of polycystic liver disease (PLD), but indications, efficacy and surgical techniques are under debate. METHODS A systematic literature search (1950-2017) of PubMed, Embase, Web of Science and the Cochrane Library was performed (CRD42017071305). Studies assessing symptomatic relief or symptomatic recurrence after laparoscopic fenestration in patients with symptomatic, non-parasitic, hepatic cysts were included. Complications were scored according to Clavien-Dindo. Methodological quality was assessed by Newcastle-Ottawa scale (NOS) for cohort studies. Pooled estimates were calculated using a random effects model for meta-analysis. RESULTS Out of 5277 citations, 62 studies with a total of 1314 patients were included. Median NOS-score was 6 out of 9. Median follow-up duration was 30 months. Symptomatic relief after laparoscopic fenestration was 90.2% (95% CI 84.3-94.9). Symptomatic recurrence was 9.6% (95% CI 6.9-12.8) and reintervention rate was 7.1% (95% CI 5.0-9.4). Post-operative complications occurred in 10.8% (95% CI 8.1-13.9) and major complications in 3.3% (95% CI 2.1-4.7) of patients. Procedure-related mortality was 1.0% (95% CI 0.5-1.6). In a subgroup analysis of PLD patients (n = 146), symptomatic recurrence and reintervention rates were significantly higher with respective rates of 33.7% (95% CI 18.7-50.4) and 26.4% (95% CI 12.6-43.0). Complications were more frequent in PLD patients, with a rate of 29.3% (95% CI 16.0-44.5). CONCLUSIONS Laparoscopic fenestration is an effective procedure for treatment of symptomatic hepatic cysts with a low symptomatic recurrence rate. The symptomatic recurrence rate and risk of complications are significantly higher in PLD patients.

Abstract
BACKGROUND Somatostatin analogues (SAs) reduce liver volume and relief symptoms in polycystic liver disease (PLD). Its effect wears off after continuing therapy suggesting development of SA tolerance in patients on chronic therapy. We postulate that a drug holiday resensitizes the liver to its acute pharmacological effects. Therefore, this study examines the liver volume-reducing effect of SAs after a drug holiday. METHODS Patients were identified from the International PLD Registry and included in our analysis when (1) treated with SAs during two cycles separated by a drug holiday and (2) height-adjusted total liver volume (hTLV) was available at start and end of each cycle. For our primary outcome we compared the effect of SAs (in % per 6 months) on hTLV between the first and second treatment cycle. RESULTS In 34 patients, initial liver volume-reducing effect was similar to that after rechallenge [-2.6% per 6 months (interquartile range, -3.8-0.8) versus -1.6% per 6 months (interquartile range, -3.1-1.1), p = 0.510]. Cessation of treatment led to a rebound effect, but liver volume remained stable compared with the baseline with intermittent therapy in responders to SA [-0.6% (interquartile range, -7.4-5.7) after 46.5 months]. CONCLUSIONS PLD patients treated with SAs benefit from retreatment after a drug holiday. The significant increase of liver volume after cessation of treatment complicates widespread use of a drug holiday as new treatment strategy. Our results contribute to a better understanding of the pharmacological effect of SAs and help to identify patients who might benefit.

Abstract
Introduction The presence of liver cirrhosis can have a major impact on pharmacodynamics and pharmacokinetics, but guidance for prescribing is lacking. Objective The aim of this study is to provide an overview of evidence-based recommendations developed for the safe use of drugs in liver cirrhosis. Methods Recommendations were based on a systematic literature search combined with expert opinion from a panel of 10 experts. The safety of each drug was classified as safe, no additional risks known, additional risks known, unsafe, unknown or the safety class was dependent on the severity of liver cirrhosis (Child–Pugh classification). If applicable, drug-specific dosing advice was provided. All recommendations were implemented in clinical decision support systems and on a website. Results We formulated 218 recommendations for a total of 209 drugs. For nine drugs, two recommendations were formulated for different administration routes or indications. Drugs were classified as ‘safe’ in 29 recommendations (13.3%), ‘no additional risks known’ in 60 (27.5%), ‘additional risks known’ in 3 (1.4%), and ‘unsafe’ in 30 (13.8%). In 57 (26.1%) of the recommendations, safety depended on the severity of liver cirrhosis and was ‘unknown’ in 39 (17.9%) recommendations. Large alterations in pharmacodynamics were the main reason for classifying a drug as ‘unsafe’. For 67 drugs (31%), a dose adjustment was needed. Conclusions Over 200 recommendations were developed for the safe use of drugs in patients with liver cirrhosis. Implementing these recommendations into clinical practice can possibly enhance medication safety in this vulnerable patient group.

Abstract
BACKGROUND Azathioprine (AZA) and mercaptopurine (MP) are the cornerstone of steroid-sparing strategies in autoimmune hepatitis (AIH). Up to 20% of patients do not tolerate or respond to these regimens. AIM To evaluate retrospectively the tolerability and efficacy of tioguanine (thioguanine) (TG) therapy in selected patients with AIH and AIH variant syndromes. METHODS Records of 52 patients who received TG therapy were retrieved from nine hospitals in the Netherlands. Indications for TG treatment were intolerable side effects on AZA or MP (n = 38), insufficient response (n = 11) or first-line treatment (n = 3). Treatment efficacy was defined as normalisation of serum aminotransferases and serum immunoglobulin G. RESULTS No serious adverse events occurred in patients treated with TG during a median follow-up of 18 months (range 1-194). Treatment was well tolerated in 41 patients (79%), whereas four had tolerable (8%) and seven (13%) intolerable side effects. Thirty-eight patients were treated with TG after intolerable side effects on AZA or MP; 29 patients continued TG therapy of whom 24 (83%) achieved complete biochemical remission, four (14%) had incomplete and one (3%) had no response; nine discontinued treatment. Seven of 11 patients with insufficient response to AZA or MP were responsive to TG, three with complete and four with incomplete biochemical remission; four discontinued due to intolerance (n = 2) and non-response (n = 2). TG was effective in all AIH patients as first-line maintenance treatment. CONCLUSION In our retrospective review of TG therapy in selected patients with AIH or AIH variants who previously failed on AZA or MP, TG appeared tolerable with biochemical efficacy.

Abstract
OBJECTIVE Alcohol-related pancreatitis is associated with a disproportionately large number of hospitalisations among GI disorders. Despite its clinical importance, genetic susceptibility to alcoholic chronic pancreatitis (CP) is poorly characterised. To identify risk genes for alcoholic CP and to evaluate their relevance in non-alcoholic CP, we performed a genome-wide association study and functional characterisation of a new pancreatitis locus. DESIGN 1959 European alcoholic CP patients and population-based controls from the KORA, LIFE and INCIPE studies (n=4708) as well as chronic alcoholics from the GESGA consortium (n=1332) were screened with Illumina technology. For replication, three European cohorts comprising 1650 patients with non-alcoholic CP and 6695 controls originating from the same countries were used. RESULTS We replicated previously reported risk loci CLDN2-MORC4, CTRC, PRSS1-PRSS2 and SPINK1 in alcoholic CP patients. We identified CTRB1-CTRB2 (chymotrypsin B1 and B2) as a new risk locus with lead single-nucleotide polymorphism (SNP) rs8055167 (OR 1.35, 95% CI 1.23 to 1.6). We found that a 16.6 kb inversion in the CTRB1-CTRB2 locus was in linkage disequilibrium with the CP-associated SNPs and was best tagged by rs8048956. The association was replicated in three independent European non-alcoholic CP cohorts of 1650 patients and 6695 controls (OR 1.62, 95% CI 1.42 to 1.86). The inversion changes the expression ratio of the CTRB1 and CTRB2 isoforms and thereby affects protective trypsinogen degradation and ultimately pancreatitis risk. CONCLUSION An inversion in the CTRB1-CTRB2 locus modifies risk for alcoholic and non-alcoholic CP indicating that common pathomechanisms are involved in these inflammatory disorders.

Abstract
AIM To evaluate the yield of routine laboratory tests and Dual Energy X-ray Absorptiometry (DEXA) scans in coeliac disease. METHODS A retrospective analysis of medical files of all followed-up patients with coeliac disease attending Rijnstate Hospital in 2016 was conducted with respect to blood tests of hemoglobin, vitamin B12, folate acid, iron status, calcium, vitamin D, glucose, thyroid function, DEXA-scans and related symptoms or signs of abnormalities. All patients had positive coeliac serology and/or biopsy-proven coeliac disease and attended regular visits after diagnosis. The chi-square test for trend was used for statistical analysis: a two-tailed probability of p < 0.05 was considered significant. RESULTS We analyzed 250 patients with a median follow-up of 7.8 (1-22) years. At diagnosis, we found anemia in 24.4%, iron deficiency in 38%, folic acid deficiency in 22.6% and vitamin B12 deficiency in 15.9%. All deficiencies recovered within 1-2 years with or without supplements. Deficiencies or autoimmune diseases occurred in 50 patients (37 possibly coeliac-related) during follow-up. Twelve cases of coeliac-related deficiencies or autoimmune diseases occurred in patients with normal values at diagnosis of whom 10 were asymptomatic (incidence 10/1000 patient years). Osteoporosis and osteopenia were present in 23.3% and 35% at diagnosis. In most patients bone mineral density (BMD) improved or stabilized during follow up (p < 0.05), 8% deteriorated. CONCLUSIONS The incidence of asymptomatic coeliac-related deficiencies or autoimmune diseases is low in patients with normal values at diagnosis. Therefore, routine laboratory screening is not necessary in this group: attending regular follow-up visits should be sufficient. DEXA scans are recommended.

Abstract
OBJECTIVE To investigate whether a novel meal service, FoodforCare, improves dietary intake and patient satisfaction, compared to the traditional 3-meals a day service (TMS). DESIGN We performed a prospective cohort study at medical (Gastroenterology) and surgical (Gynecology, Urology, Orthopedics) wards. Patients were offered TMS (July 2015 - May 2016; n = 326) or FfC meal service (after stepwise introduction per ward from January 2016 - December 2016; n = 311). METHOD Primary outcome was the mean percentage of protein and energy intake relative to requirements, between patients receiving TMS and those receiving FfC, on the first and fourth day of full oral intake. Patient satisfaction comprised rating of the experienced quality of the meals and the meal service by means of a validated questionnaire. RESULTS Patient characteristics were similar between groups, with the exception that the FfC group contained more oncology patients (p = 0.028). FfC improved mean daily protein intake (in g/day) relative to requirements (1.2 g/kg/day) at day 1 (mean % ± SD: 79 ± 33 vs. 59 ± 28; p < 0.05) and day 4 (73 ± 38 vs. 59 ± 29; p < 0.05). Mean daily energy intake (in kcal/day) relative to requirements improved at day 1 (88 ± 34 vs. 70 ± 30; p < 0.05) and day 4 (84 ± 40 vs. 73 ± 31; p = 0.05). On a scale of 1-10, patient satisfaction remained unchanged, in terms of food quality (7.7 ± 1.5 vs. 7.4 ± 1.4; p = 0.09) and meal service (7.8 ± 1.3 vs. 7.7 ± 1.1; p = 0.29). The FfC group was more satisfied with the appearance and smell of the meals (both p < 0.05). CONCLUSION Implementation of this novel meal service substantially improved protein and energy intake while maintaining, and to some extent, improving patient satisfaction.
