Abstract
BACKGROUND & AIMS Polycystic liver disease (PLD) follows a progressive course ultimately leading to severe hepatomegaly and mechanical complaints in a subset of patients. It is still unknown to what extent this compromises health-related quality of life (HRQL). Our aim was to determine HRQL in PLD patients and investigate its association with concurrent abdominal symptoms and liver volume. METHODS Pooled data of 92 severe PLD patients from two randomized clinical trials were used for our cross-sectional analysis. HRQL was assessed using the generic short-form health survey (SF-36) resulting in eight scale scores and the summarizing physical (PCS) and mental component score (MCS). Subsequently, these were compared with the general population. Abdominal symptoms were measured with a standardized, 7-point scale questionnaire in 54 patients. We dichotomized symptoms for absence or presence and compared them with the component scores. Finally, a possible correlation between liver volume and HRQL was explored. RESULTS Demographics showed severe polycystic livers (mean 4906 ± 2315 ml). PCS was significantly lower compared with the general population (P < 0.001), in contrast with a similar MCS (P = 0.82). PLD patients had statistically significant (P < 0.05) diminished physical functioning, role physical, general health, vitality and social functioning scores. Upper- and lower abdominal pain and dyspnoea were significantly associated with a reduced PCS (P < 0.01). No correlation was found between liver volume and HRQL. CONCLUSION Polycystic liver disease patients had significantly lower HRQL in the physical dimension compared with the general population. Abdominal pain and dyspnoea had a significant impact on this physical dimension of HRQL.

Abstract
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). METHODS Clinical characteristics were collected from 1313 AIH patients (78% females) from 31 centers, including all eight academic centers in the Netherlands. Additional data on ethnicity, family history and symptoms were obtained by the use of a questionnaire. RESULTS The prevalence of AIH was 18.3 (95% confidential interval [CI]: 17.3-19.4) per 100,000 with an annual incidence of 1.1 (95% CI: 0.5-2) in adults. An incidence peak was found in middle-aged women. At diagnosis, 56% of patients had fibrosis and 12% cirrhosis in liver biopsy. Overall, 1% of patients developed HCC and 3% of patients underwent liver transplantation. Overlap with primary biliary cirrhosis and primary sclerosing cholangitis was found in 9% and 6%, respectively. The clinical course did not differ between Caucasian and non-Caucasian patients. Other autoimmune diseases were found in 26% of patients. Half of the patients reported persistent AIH-related symptoms despite treatment with a median treatment period of 8 years (range 1-44 years). Familial occurrence was reported in three cases. CONCLUSION This is the largest epidemiological study of AIH in a geographically defined region and demonstrates that the prevalence of AIH in the Netherlands is uncommon. Although familial occurrence of AIH is extremely rare, our twin data may point towards a genetic predisposition. The high percentage of patients with cirrhosis or fibrosis at diagnosis urges the need of more awareness for AIH.

Abstract
BACKGROUND A new era for the treatment of chronic hepatitis C is about to transpire. With the introduction of the first-generation protease inhibitors the efficacy of hepatitis C treatment improved significantly. Since then, the therapeutic agenda has moved further forward with the recent approval of sofosbuvir and the expected approval of agents such as simeprevir and daclatasvir. This paper, developed parallel to the approval of sofosbuvir, is to serve as a guidance for the therapeutic management of chronic hepatitis C. METHODS We performed a formal search through PubMed, Web of Science and ClinicalTrials.gov to identify all clinical trials that have been conducted with EMA-approved new agents in hepatitis C; for this version (April 2014) we focused on sofosbuvir. For each disease category, the evidence was reviewed and recommendations are based on GRADE. RESULTS We identified 11 clinical trials with sofosbuvir and for each disease category recommendations for treatment are made. Not all disease categories were studied extensively and therefore in some cases we were unable to provide recommendations. CONCLUSION The recent approval of sofosbuvir will most likely change the therapeutic landscape of chronic hepatitis C. The use of sofosbuvir-containing regimens can shorten the duration of therapy, increase efficacy and result in less side effects, compared with standard of care. The efficacy relative to standard of care needs to be weighed against the increased costs of sofosbuvir. With future approval of the other direct-acting antivirals, the outcome of hepatitis C treatment will likely improve further and this guidance will be updated.

Abstract
Obesity and metabolic syndrome are healthcare problems that continue to rise in frequency worldwide. Both phenotypes are a strong predictor for development of liver steatosis in the context of non-alcoholic fatty liver disease or non-alcoholic steatohepatitis. Ultrasound may detect steatosis, but its sensitivity is limited and liver biopsy is still considered to be the gold standard. Less invasive techniques that accurately quantify liver steatosis are warranted. Jiménez-Agüero and colleagues propose that multi-echo magnetic resonance imaging might be such a diagnostic tool. They validated multi-echo magnetic resonance imaging with measured hepatic triglyceride concentration. Their results show that this innovative technique measures the grade of steatosis in different clinical situations. Therefore, multi-echo magnetic resonance imaging might be considered for monitoring liver steatosis as an intermediate endpoint. Wide clinical applicability is limited though, as it does not allow differentiation between non-alcoholic fatty liver disease and non-alcoholic steatohepatitis.

Abstract
OBJECTIVE According to screening studies, celiac disease (CD) is prevalent in Western Europe. Actual prevalence tends to be much lower. The width of this actual gap is determined by the balance between disease symptoms and the "case-finding" capabilities of the healthcare system. Therefore, we conducted a nationwide study to determine the temporal trends in the incidence in the Netherlands including a focus on demographic aspects. MATERIALS AND METHODS We performed a nationwide search in the Dutch Pathology Registry (PALGA) to identify all biopsy-proven cases of CD in five different years between 1995 and 2010. Furthermore, demographic profiles and socioeconomic status (SES) of patients were studied. RESULTS The overall incidence of CD increased from 2.72 (confidence interval [CI] 2.46-2.99) in 1995 to 6.65 (CI 6.27-7.06) per 100,000 inhabitants in 2010. No significant regional differences were noticed. In men, rates increased from 2.28 (CI 1.95-2.65) to 4.71 (CI 4.25-5.20) per 100,000 in 2010. In women, the increase was from 3.27 (CI 2.88-3.70) to 8.66 (CI 8.04-9.31) per 100,000 in 2010. A trend toward leveling of incidence was observed from 2008 to 2010. Patients diagnosed during childhood live in areas with a higher SES compared with patients diagnosed at adult age. CONCLUSION The incidence of biopsy-proven CD in the Netherlands increased almost threefold between 1995 and 2010. In areas with a higher SES, relatively more children were diagnosed.

Abstract
BACKGROUND & AIMS Autoimmune hepatitis (AIH) is an uncommon autoimmune liver disease of unknown etiology. We used a genome-wide approach to identify genetic variants that predispose individuals to AIH. METHODS We performed a genome-wide association study of 649 adults in The Netherlands with AIH type 1 and 13,436 controls. Initial associations were further analyzed in an independent replication panel comprising 451 patients with AIH type 1 in Germany and 4103 controls. We also performed an association analysis in the discovery cohort using imputed genotypes of the major histocompatibility complex region. RESULTS We associated AIH with a variant in the major histocompatibility complex region at rs2187668 (P = 1.5 × 10(-78)). Analysis of this variant in the discovery cohort identified HLA-DRB1*0301 (P = 5.3 × 10(-49)) as a primary susceptibility genotype and HLA-DRB1*0401 (P = 2.8 × 10(-18)) as a secondary susceptibility genotype. We also associated AIH with variants of SH2B3 (rs3184504, 12q24; P = 7.7 × 10(-8)) and CARD10 (rs6000782, 22q13.1; P = 3.0 × 10(-6)). In addition, strong inflation of association signal was found with single-nucleotide polymorphisms associated with other immune-mediated diseases, including primary sclerosing cholangitis and primary biliary cirrhosis, but not with single-nucleotide polymorphisms associated with other genetic traits. CONCLUSIONS In a genome-wide association study, we associated AIH type 1 with variants in the major histocompatibility complex region, and identified variants of SH2B3and CARD10 as likely risk factors. These findings support a complex genetic basis for AIH pathogenesis and indicate that part of the genetic susceptibility overlaps with that for other immune-mediated liver diseases.

Abstract
BACKGROUND Up to 41% of patients report pain after cholecystectomy and in most studies follow-up for these symptoms did not exceed 5 years. The episodic nature of abdominal pain associated with symptomatic cholelithiasis warrants long-term follow-up studies. We assessed which patient and surgical factors were associated with absence of pain and patient-reported success of surgery after ≥ 5 years of follow-up. METHODS Patients of ≥ 18 years of age with symptomatic cholelithiasis, classified as ASA I or II, who had previously returned a preoperative questionnaire were sent a questionnaire consisting of the gastrointestinal quality of life index (GIQLI) and patient ratings of current versus presurgical abdominal symptoms and of surgery result. Logistic regression analysis was performed to determine associations. RESULTS Questionnaires were sent to 197 patients and returned by 126 (64.0%) patients (73.8 % female, mean age at surgery 47.5 ± 12.2 years) at a mean of 10.0 ± 1.0 years after cholecystectomy. Absence of abdominal pain was reported by 60.3% of the patients. Patients classified as ASA II as opposed to ASA I were less likely to report absence of pain (OR 0.41, 95% CI 0.17-0.99). A positive rating of long-term postsurgical versus presurgical abdominal symptoms was given by 89.7% of the patients and 90.5% considered the cholecystectomy result to be good. No variables were significantly associated with these latter two outcome measures. CONCLUSIONS We found a high patient-reported surgery success rate after >5 years of follow-up after cholecystectomy despite residual abdominal pain in some of these patients. None of the patient and surgery-related characteristics were consistently associated with all three outcome measures. This discrepancy between patient' outcomes highlights the need for realistic expectations prior to cholecystectomy.

Abstract
Polycystic livers are seen in the rare inherited disorder isolated polycystic liver disease (PCLD) and are recognized as the most common extrarenal manifestation in autosomal dominant polycystic kidney disease. Hepatic cystogenesis is characterized by progressive proliferation of cholangiocytes, ultimately causing hepatomegaly. Genetically, polycystic liver disease is a heterogeneous disorder with incomplete penetrance and caused by mutations in PRKCSH, SEC63, PKD1, or PKD2. Genome-wide SNP typing and Sanger sequencing revealed no pathogenic variants in hitherto genes in an extended PCLD family. We performed whole-exome sequencing of DNA samples from two members. A heterozygous variant c.3562C > T located at a highly conserved amino acid position (p.R1188W) in the low density lipoprotein receptor-related protein 5 (LRP5) gene segregated with the disease (logarithm of odds score, 4.62) but was not observed in more than 1,000 unaffected individuals. Screening of LRP5 in a PCLD cohort identified three additional mutations in three unrelated families with polycystic livers (p.V454M, p.R1529S, and p.D1551N), again all undetected in controls. All variants were predicted to be damaging with profound structural effects on LRP5 protein domains. Liver cyst tissue and normal hepatic tissue samples from patients and controls showed abundant LRP5 expression by immunohistochemistry. Functional activity analyses indicated that mutant LRP5 led to reduced wingless signal activation. In conclusion, we demonstrate that germ-line LRP5 missense mutations are associated with hepatic cystogenesis. The findings presented in this study link the pathophysiology of PCLD to deregulation of the canonical wingless signaling pathway.

Abstract
Polycystic livers are found in autosomal dominant polycystic kidney disease (ADPKD), caused by polycystic kidney disease (PKD)1 and PKD2 mutations in virtually all cases, and in isolated polycystic liver disease (PCLD), where 20% of cases are caused by mutations in Protein kinase C substrate 80K-H (PRKCSH) or SEC63. Loss of heterozygosity in single hepatoblasts leads to underlying cystogenic ductal plate malformations. Crucially, actual components driving this development remain elusive. Recent advances have unraveled the roles of transforming growth factor (TGF)-β, Notch and Wnt signaling, transcriptional regulators such as hepatocyte nuclear factor (HNF)6 and HNF1β, as well as cilium function in hepatobiliary organogenesis. In polycystic liver disease, mutation or defective co-translational processing of key elements required for primary cilium formation have been implicated. This review recapitulates liver patterning factors in hepatobiliary development and extracts molecular players in hepatic cystogenesis.

Abstract
Gallstone disease is one of the most common problems in the gastroenterology and is associated with significant morbidity. It may present as stones in the gallbladder (cholecystolithiasis) or in the common bile duct (choledocholithiasis). At the end of the 1980s laparoscopy was introduced and first laparoscopic cholecystectomy was performed in 1985. The laparoscopic technique for removing the gallbladder is the current treatment of choice, although indications for open surgery exist. To perform laparoscopic cholecystectomy as safe as possible multiple safety measures were developed. The gold standard for diagnosing and removing common bile duct stones is Endoscopic Retrograde Cholangiopancreatography (ERCP). The surgical treatment option for choledocholithiasis is laparoscopic cholecystectomy with common bile duct exploration. If experience is not available, than ERCP followed by elective cholecystectomy is by far the best therapeutic modality. The present review will discuss the use, benefits and drawbacks of laparoscopy in patients with cholecystolithiasis and choledocholithiasis.

Abstract
BACKGROUND Plasmacytoid dendritic cells have been implicated in the pathogenesis of systemic sclerosis through mechanisms beyond the previously suggested production of type I interferon. METHODS We isolated plasmacytoid dendritic cells from healthy persons and from patients with systemic sclerosis who had distinct clinical phenotypes. We then performed proteome-wide analysis and validated these observations in five large cohorts of patients with systemic sclerosis. Next, we compared the results with those in patients with systemic lupus erythematosus, ankylosing spondylitis, and hepatic fibrosis. We correlated plasma levels of CXCL4 protein with features of systemic sclerosis and studied the direct effects of CXCL4 in vitro and in vivo. RESULTS Proteome-wide analysis and validation showed that CXCL4 is the predominant protein secreted by plasmacytoid dendritic cells in systemic sclerosis, both in circulation and in skin. The mean (±SD) level of CXCL4 in patients with systemic sclerosis was 25,624±2652 pg per milliliter, which was significantly higher than the level in controls (92.5±77.9 pg per milliliter) and than the level in patients with systemic lupus erythematosus (1346±1011 pg per milliliter), ankylosing spondylitis (1368±1162 pg per milliliter), or liver fibrosis (1668±1263 pg per milliliter). CXCL4 levels correlated with skin and lung fibrosis and with pulmonary arterial hypertension. Among chemokines, only CXCL4 predicted the risk and progression of systemic sclerosis. In vitro, CXCL4 down-regulated expression of transcription factor FLI1, induced markers of endothelial-cell activation, and potentiated responses of toll-like receptors. In vivo, CXCL4 induced the influx of inflammatory cells and skin transcriptome changes, as in systemic sclerosis. CONCLUSIONS Levels of CXCL4 were elevated in patients with systemic sclerosis and correlated with the presence and progression of complications, such as lung fibrosis and pulmonary arterial hypertension.

Abstract
If left untreated, hepatitis C infection can lead to hepatitis, liver fibrosis, cirrhosis and hepatocellular carcinoma. Until recently, the standard-of-care was peginterferon with ribavirin. Sofosbuvir is a novel direct antiviral acting agent that targets hepatitis C. Administration of sofosbuvir leads to high cure rates, but is very expensive. Here we question the concept of the value-based pricing of sofosbuvir, and argue that the spiralling price of new drugs leads to an unsustainable healthcare system.

Abstract
BACKGROUND & AIMS Although restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) substantially reduces the risk of colorectal cancer in patients with inflammatory bowel disease (IBD), subsequent pouch neoplasia can develop. There are few data on the incidence of and risk factors for neoplasia, so there is no consensus on the need for pouch surveillance. We aimed to determine the cumulative incidence of pouch neoplasia in patients with IBD and identify risk factors for developing pouch neoplasia. METHODS We searched the Dutch Pathology Registry (PALGA) to identify all patients with IBD and IPAA in The Netherlands from January 1991 to May 2012. We calculated the cumulative incidence of pouch neoplasia and performed a case-control study to identify risk factors. Demographic and clinical variables were analyzed with univariable and multivariable Cox regression analyses. RESULTS We identified 1200 patients with IBD and IPAA; 25 (1.83%) developed pouch neoplasia, including 16 adenocarcinomas. Respective cumulative incidences at 5, 10, 15, and 20 years were 1.0%, 2.0%, 3.7%, and 6.9% for pouch neoplasia and 0.6%, 1.4%, 2.1%, and 3.3% for pouch carcinoma. A history of colorectal neoplasia was the only risk factor associated with pouch neoplasia. Hazard ratios were 3.76 (95% confidence interval, 1.39-10.19) for prior dysplasia and 24.69 (95% confidence interval, 9.61-63.42) for prior carcinoma. CONCLUSIONS The incidence of pouch neoplasia in patients with IBD without a history of colorectal neoplasia is relatively low. Prior dysplasia or colon cancer is associated with an approximate 4- and 25-fold increase in risk, respectively, of developing pouch neoplasia.

Abstract
BACKGROUND There are limited therapeutic options to slow the progression of autosomal dominant polycystic kidney disease (ADPKD). Recent clinical studies indicate that somatostatin analogues are promising for treating polycystic liver disease and potentially also for the kidney phenotype. We report on the design of the DIPAK 1 (Developing Interventions to Halt Progression of ADPKD 1) Study, which will examine the efficacy of the somatostatin analogue lanreotide on preservation of kidney function in ADPKD. STUDY DESIGN The DIPAK 1 Study is an investigator-driven, randomized, multicenter, controlled, clinical trial. SETTING & PARTICIPANTS We plan to enroll 300 individuals with ADPKD and estimated glomerular filtration rate (eGFR) of 30-60 mL/min/1.73 m(2) who are aged 18-60 years. INTERVENTION Patients will be randomly assigned (1:1) to standard care or lanreotide, 120 mg, subcutaneously every 28 days for 120 weeks, in addition to standard care. OUTCOMES Main study outcome is the slope through serial eGFR measurements starting at week 12 until end of treatment for lanreotide versus standard care. Secondary outcome parameters include change in eGFR from pretreatment versus 12 weeks after treatment cessation, change in kidney volume, change in liver volume, and change in quality of life. MEASUREMENTS Blood and urine will be collected and questionnaires will be filled in following a fixed scheme. Magnetic resonance imaging will be performed for assessment of kidney and liver volume. RESULTS Assuming an average change in eGFR of 5.2 ± 4.3 (SD) mL/min/1.73 m(2) per year in untreated patients, 150 patients are needed in each group to detect a 30% reduction in the rate of kidney function loss between treatment groups with 80% power, 2-sided α = 0.05, and 20% protocol violators and/or dropouts. LIMITATIONS The design is an open randomized controlled trial and measurement of our primary end point does not begin at randomization. CONCLUSIONS The DIPAK 1 Study will show whether subcutaneous administration of lanreotide every 4 weeks attenuates disease progression in patients with ADPKD.

Abstract
BACKGROUND Bleomycin has become an integral part of chemotherapy in patients with germ-cell tumors. One of the most feared side effects is bleomycin-induced pneumonitis. In patients with mild or moderate BIP, radiological signs disappear almost completely within nine months after discontinuation of bleomycin treatment. CASE PRESENTATION We present a patient with a history of non seminoma of the testis and bleomycin-induced pneumonitis. During follow-up, regression of the hypothesis of eosinophilic migration to the liver after regression of bleomycin-induced pneumonitis is highly suspicious based on transient eosinophilia and focal eosinophilic liver disease. CONCLUSION As follow up may consist of CT scanning in germ-line tumor patients, transient eosinophilic liver lesions reported during regressive bleomycin-induced pneumonitis should not be presumed automatically as metastatic tumor relapse and require further sequential imaging and pathological examination.

Abstract
In this new Dutch guideline for hepatitis C virus infection we provide recommendations for the management of hepatitis C infection. Until 2012 the standard for treatment consisted of pegylated interferon alpha (peg-IFNa) and ribavirin. The advent of first-generation direct antiviral agents such as boceprevir and telaprevir has changed the concept of treatment of adult chronic hepatitis C genotype 1 infected patients. There are three benefits of boceprevir and telaprevir. They increase the likelihood of cure in 1) naive genotype 1 patients and 2) in patients who did not respond to earlier treatment with peg-IFNa and ribavirin, while 3) allowing shortening of treatment duration from 48 weeks to 24 or 28 weeks, which is possible in 40-60% of non-cirrhotic naive (boceprevir and telaprevir) and relapsing patients (telaprevir). The use of boceprevir and telaprevir is associated with multiple side effects and awareness of these side effects is needed to guide the patient through the treatment process. This guideline, formulated on behalf of The Netherlands Association of Hepato-gastroenterologists, The Netherlands Association of Internal Medicine, and The Dutch Association for the Study of Liver Disease, serves as a manual for physicians for the management and treatment of acute and chronic hepatitis C virus monoinfection in adults.

Young women with polycystic liver disease respond best to somatostatin analogues: a pooled analysis of individual patient data. Gastroenterology 2013; 145:357-65.e1-2. [PMID: 23665274 DOI: 10.1053/j.gastro.2013.04.055] [Citation(s) in RCA: 61] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2013] [Revised: 04/15/2013] [Accepted: 04/30/2013] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Clinical trials have shown that in patients with polycystic liver disease (PLD), short-term treatment with somatostatin analogues (SAs) reduces liver volumes by 4.5%-5.9%, compared with placebo. However, the effects of SA therapy vary among individuals. We collected data from individual patients with PLD to identify subgroups that benefit most from SA therapy. METHODS We analyzed data from 107 patients with PLD from 3 randomized placebo-controlled trials (67 received SAs, 52 received placebo). We used multiple linear regression analysis to determine the effects of SAs based on patients' age, sex, baseline liver volume, and diagnosis (autosomal dominant polycystic liver or kidney disease). The primary outcome was change in liver volume after 6-12 months of treatment. RESULTS The effects of SA therapy did not differ significantly among patients with different diagnoses or baseline liver volumes; the overall difference in liver volume between groups receiving SAs therapy vs placebo was 5.3% (P < .001). Among subjects given placebo, young women (48 years old or younger) had the greatest increase in polycystic liver volume (4.8%; 95% confidence interval: 2.2%-7.4%), and mean liver volumes did not increase in older women and men. Women 48 years old or younger had a greater response to therapy (a reduction in liver volume of 8.0% compared with placebo; P < .001) than older women (a reduction in liver volume of 4.1% compared with placebo; P = .022). CONCLUSIONS Based on a pooled analysis of data from individual patients with PLD, treatment with somatostatin analogues is equally effective for patients with autosomal dominant polycystic kidney disease or polycystic liver disease; efficacy does not depend on size of the polycystic liver. Young female patients appear to have the greatest benefit from 6-12 months of SA therapy, which might avert the progressive course of the disease in this specific group.

Abstract
BACKGROUND & AIMS Single nucleotide polymorphisms (SNP) in the Cytotoxic T lymphocyte antigen-4 gene (CTLA-4) have been associated with several autoimmune diseases including autoimmune Hepatitis (AIH). In this chronic idiopathic inflammatory liver disease, conflicting results have been reported on the association with a SNP at position +49 in the CTLA-4 gene in small patient cohorts. Here, we established the role of this SNP in a sufficiently large cohort of AIH patients. METHODS The study population consisted of 672 AIH patients derived from academic and regional hospitals in the Netherlands and was compared with 500 controls selected from the 'Genome of the Netherlands' project cohort. Genotype frequencies were assessed by PCR for patients and by whole genome sequencing for controls. RESULTS No significant differences in allele frequencies were found between patients and controls (G Allele: 40% vs 39%, P = 0.7). Similarly, no significant differences in genotype frequencies between patients and controls were found. Finally, there was no relation between disease activity and the G allele or AG and GG genotypes. CONCLUSION The Cytotoxic T Lymphocyte Antigen-4 +49 A/G polymorphism does not represent a major susceptibility risk allele for AIH in Caucasians and is not associated with disease severity at presentation.

Abstract
BACKGROUND & AIMS Polycystic liver disease (PLD) is associated with autosomal dominant polycystic kidney disease (ADPKD) or autosomal dominant polycystic liver disease (PCLD). The resulting hepatomegaly compromises quality of life. Somatostatin analogues reduce PLD volume by approximately 5% when given for 6-12 months. A pilot trial in 16 ADPKD patients demonstrated that sirolimus, an mTOR inhibitor, reduced PLD volume by 26%. The aim of this study was to assess the PLD volume reducing effect of everolimus and octreotide relative to octreotide monotherapy. METHODS We designed a randomized controlled trial that compared 48 weeks of everolimus 2.5 mg daily, combined with octreotide 40 mg intramuscularly every 4 weeks, to octreotide monotherapy. We included PCLD and ADPKD patients. Exclusion criteria were MDRD-GFR <60 ml/min/1.73 m(2) and liver volume <2500 ml. Primary outcome was change in liver volume measured with CT-volumetry. RESULTS We randomized 44 PLD patients (29 PCLD, 15 ADPKD, 89% female) to treatment with octreotide (n=23) or octreotide-everolimus (n=21). Liver volume decreased by 3.5% (p<0.01) in the monotherapy arm, compared to 3.8% with combination therapy (p<0.01). The difference between treatment arms was not significant (p=0.73). CONCLUSIONS Adding everolimus to octreotide in PLD does not increase the liver volume reducing effect of octreotide.

Abstract
BACKGROUND Identifying and monitoring high-risk patients can aid the prevention of esophageal cancer (EC). The interaction of environmental risk factor exposure and genetic susceptibility may contribute to the etiology of EC. Biotransformation enzymes such as Glutathione S-Transferases (GSTs ) detoxify mutagenic and genotoxic compounds and therefore control the rate of detoxification of carcinogens. Functional polymorphisms in the genes coding for GSTs alter their enzyme activity in vitro, and were reported to modify EC risk in Asians. We hypothesized that altered enzyme activity GST genotypes influence the susceptibility for esophageal adeno- (EAC) and squamous cell carcinoma (ESCC) in Caucasians. METHODS We performed a case-control study including 440 Caucasian patients with EC and 592 healthy Caucasian controls matched for age and sex. Functional polymorphisms were selected and genotypes were determined in GST classes Alpha, Mu, Theta and Pi by means of polymerase chain reaction. Genotypes were classified into predicted high, intermediate and low enzyme activity categories based on in vitro activity data. The distribution of the activity genotypes were compared between patients with EAC or ESCC, and controls. Odds ratios (OR) with 95% confidence intervals (CI) were calculated by logistic regression analyses. Gene-gene interactions were tested and for comparison purposes, the predicted low and intermediate activity genotypes were combined. Genotypes with similar risks for EAC or ESCC were combined and analyzed for multiplicative effects. RESULTS Our analyses includes 327 patients with EAC and 106 patients with ESCC. Low or intermediate activity enzyme genotypes for GSTM1, GSTA1, GSTP1 I105V and A114V as well as for GSTT1, did not significantly modify the risk for ESCC or EAC in our Dutch population. CONCLUSION Functional genotypes in GST genes are not involved in EAC or ESCC susceptibility in Caucasians, in contrast to results on ESCC from Asia or Africa.

Abstract
Barrett's esophagus, with gastroesophageal reflux disease and obesity as risk factors, predisposes to esophageal adenocarcinoma (EAC). Recently a British genome wide association study identified two Barrett's esophagus susceptibility loci mapping within the major histocompatibility complex (MHC; rs9257809) and closely to the Forkhead-F1 (FOXF1; rs9936833) coding gene. An interesting issue is whether polymorphisms associated with Barrett's esophagus, are also implicated in esophageal carcinoma (EC), and more specifically EAC genesis. Assessing the individual genetic susceptibility can help identify high risk patients more prone to benefit from surveillance programs. Our hypothesis: Barrett associated MHC and FOXF1 variants modify EC risk in Caucasians. In a Dutch case-control study, 431 patients with EC and 605 healthy controls were included. Polymorphisms at chromosomes 6p21 (MHC) and 16q24 (FOXF1) were determined by means of real-time polymerase chain reaction (RT-PCR). Logistic regression analysis was used to calculate odds ratios with 95% confidence intervals. The FOXF1 rs9936833 variant C allele was associated with an increased EAC susceptibility; OR, [95% CI]; 1.21, [0.99-1.47]. A sex-stratified analysis revealed a similar association in males; 1.24 [1.00-1.55]. The variant MHC rs9257809 G allele as well as the MHC heterozygous AG genotype significantly increased ESCC risk; 1.76 [1.16-2.66] and 1.74 [1.08-2.80], respectively. Sex-stratification showed that the variant G allele was especially present in female patients; 2.32 [1.04-5.20]. In conclusion, this study provides evidence that MHC rs9257809 and FOXF1 rs9936833 variants, associated with Barrett's esophagus, also increase ESCC and EAC susceptibility in Caucasians. FOX proteins are transcription factors involved in organogenesis of the GI tract, while MHC haplotypes are strongly associated with smoking behavior, a crucial risk factor for ESCC. Assessing the individual genetic susceptibility can help identify high risk patients more prone to benefit from (Barrett) surveillance programs.
