  • Ingår i: Lancet Gastroenterology & Hepatology. - : Elsevier BV. - 2468-1253. ; 7:6, s. 513-521

    • Background Screening for colorectal cancer is done with lower gastrointestinal endoscopy or stool-based tests. There is little evidence from randomised trials to show primary colonoscopy reduces mortality in colorectal cancer We aimed to investigate the effect of screening with once-only colonoscopy or two rounds of faecal immunochemical test screening on colorectal cancer mortality and incidence. Methods We did a randomised controlled trial in Sweden (SCREESCO). Residents in 18 of 21 regions who were age 60 years in the year of randomisation were identified from a population register maintained by the Swedish Tax Agency. A statistician with no further involvement in the trial used a randomised block method to assign individuals to once-only colonoscopy, two rounds of faecal immunochemical testing (OC-Sensor; 2 years apart), or a control group (no intervention; standard diagnostic pathways), in a ratio of 1:6 for colonoscopy versus control and 1:2 for faecal immunochemical testing versus control. Masking was not possible due to the nature of the trial. The primary endpoints of the trial are colorectal cancer mortality and colorectal cancer incidence. Here, we report preliminary participation rates, baseline findings, and adverse events from March, 2014, to December, 2020, in the two intervention groups after completion of recruitment and screening, up to the completion of the second faecal immunochemical testing round. Analyses were done in the intention-to-screen population, defined as all individuals who were randomly assigned to the respective study group. This study is registered with Clinical Trials.gov, NCT02078804. Findings Between March 1, 2014, and Dec 31, 2020, 278 280 people were induded in the study; 31 140 were assigned to the colonoscopy group, 60 300 to the faecal immunochemical test group, and 186 840 to the control group. 10 679 (35.1%) of 30 400 people who received an invitation for colonoscopy participated. 33 383 (55.5%) of 60 137 people who received a postal faecal immunochemical test participated. In the intention-to-screen analysis, colorectal cancer was detected in 49 (0.16%) of 31140 people in the colonoscopy group versus 121 (0. 20%) of 60 300 in the faecal immunochemical test group (relative risk [RR] 0.78, 95% CI 0.56-1.09). Advanced adenomas were detected in 637 (2.05%) people in the colonoscopy group and 968 (1.61%) in the faecal immunochemical test group (RR 1.27, 95% CI 1.15-1.41). Colonoscopy detected more right-sided advanced adenomas than faecal immunochemical testing. There were two perforations and 15 major bleeds in 16 555 colonoscopies. No intervention-related deaths occurred. Interpretation The diagnostic yield and the low number of adverse events indicate that the design from this trial, both for once-only colonoscopy and faecal immunochemical test screening, could be transferred to a population-based screening service if a benefit in disease-specific mortality is subsequently shown.

  • Factors influencing the response to interferon therapy in chronic hepatitis C. Studies on viral genotype and induction of 2',5'-oligoadenylate synthetase in the liver and peripheral blood cells
  • 1996
  • Ingår i: Scandinavian Journal of Gastroenterology. - : Informa UK Limited. - 1502-7708 .- 0036-5521. ; 31:6, s. 604-611
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The mechanism behind the antiviral action of interferon (IFN) therapy in chronic hepatitis C virus (HCV) infection is not well understood, and, furthermore, few factors have been shown to be good predictors of a favourable response to IFN treatment in chronic HCV infection. METHODS: Freshly explanted liver cells and peripheral blood mononuclear cells (PBMC) from 80 patients with chronic HCV infection were used to study the capacity of IFN to induce the enzyme 2',5'-oligoadenylate synthetase (2'5'-AS) in vitro. The HCV genotype was determined in 53 patients. The induction of 2'5'-AS was correlated to the results of IFN-alpha treatment in 36 patients. RESULTS: Normalization of transaminases during IFN treatment was significantly associated with 2'5'-AS levels in liver cells cultured in the absence of IFN. A similar tendency, although not statistically significant, was found for IFN-induced levels of 2'5'-AS in liver cells. No such associations were found when PBMC were analysed. Six patients showed a sustained biochemical response. These six did not deviate significantly from the remaining patients with regard to base-line or IFN-induced levels of 2'5'-AS in liver cells or PBMC. Eradication of HCV RNA during IFN treatment did not correlate with 2'5'-AS levels in liver cells. Comparison of HCV genotype and clinical response showed that patients with genotype 3a had the most favourable outcome. No association was found between liver histology and treatment outcome. CONCLUSION: These data imply that direct effects of IFN on liver cells are of importance for the response to IFN treatment.

  • High dose ursodeoxycholic acid in primary sclerosing cholangitis does not prevent colorectal neoplasia
  • 2012
  • Ingår i: Alimentary Pharmacology and Therapeutics. - Malden : Wiley. - 0269-2813 .- 1365-2036. ; 35:4, s. 451-457
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Patients with primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD) have a high risk of developing colorectal cancer and dysplasia. Ursodeoxycholic acid (UDCA) has been suggested to have chemopreventive effects on the development of colorectal cancer and dysplasia but long-term data and larger trials are lacking. Aim To evaluate the effect of high dose (17-23 mg/kg/day) UDCA on colorectal neoplasia in a cohort of patients with PSC and IBD. Methods From our previous 5-year randomised controlled trial of UDCA vs. placebo in PSC, we performed a follow-up of 98 patients with concomitant IBD from entry of the trial 1996-1997 until 2009 for development of colorectal cancer or dysplasia. Results The total follow-up time was 760 person-years. Dysplasia/cancer-free survival was compared between placebo-(n = 50) and UDCA-treated (n = 48) patients. There was a similar frequency of dysplasia or cancer after 5 years between patients originally assigned to UDCA or placebo (13% vs. 16%) and no difference in dysplasia/cancer-free survival (P = 0.46, log rank test). At the end of 2009 no difference in cancer-free survival was detected, 30% of the placebo patients compared with 27% of UDCA patients had developed colorectal cancer or dysplasia. Conclusions Long-term high dose ursodeoxycholic acid does not prevent colorectal cancer or dysplasia in patients with primary sclerosing cholangitis-associated inflammatory bowel disease.

  • Alcohol and drug use prior to liver transplantation: more common than expected in patients with non-alcoholic liver disease
  • 2019
  • Ingår i: Scandinavian Journal of Gastroenterology. - : Informa UK Limited. - 0036-5521 .- 1502-7708. ; 54:9, s. 1146-1154
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: Liver transplantation (LT) is a life-saving procedure for patients with end-stage liver disease, acute liver failure or hepatocellular carcinoma (HCC). Patients with known alcoholic liver cirrhosis (ALC) are usually assessed by an addiction specialist, but patients with other liver diseases may also exhibit harmful drinking. This study aims to assess the drinking habits in LT-recipients with or without a diagnosis of ALC. Patients and methods: Between April 2012 and December 2015, 190 LT-recipients were interviewed using the Lifetime Drinking History (LDH) and the Addiction Severity Index (ASI). Patients were categorized according to their diagnoses: ALC (group A, n = 39), HCC or hepatitis C (group B, n = 56) or other liver diseases (group C, n = 95). Data were analysed using descriptive statistic methods. Results: Fifteen of 95 patients (15.8%) in group C - a cohort without suspected addiction problems - had either alcohol consumption or binge drinking within the upper quartile of the overall cohort. The aetiology of liver disease in this subgroup included mainly cholestatic and cryptogenic liver disease. Illicit drugs had been used by 35% of all patients. Cannabis and amphetamine were the most common drugs and had the longest duration of regular use. Conclusions: LT candidates without known alcohol or drug use may have a clinically significant consumption of alcohol and previous illicit drug use. Efforts should be put on identification of these patients during LT evaluation. The use of structured questionnaires such as the ASI and the LDH could facilitate detection of alcohol and drug problems.

  • Colorectal cancer screening with fecal immunochemical testing or primary colonoscopy: An analysis of health equity based on a randomised trial
  • 2022
  • Ingår i: eClinicalMedicine. - : Elsevier BV. - 2589-5370. ; 47
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: We have addressed health equity attained by fecal immunochemical testing (FIT) and primary colonoscopy (PCOL), respectively, in the randomised controlled screening trial SCREESCO conducted in Sweden. Methods: We analysed data on the individuals recruited between March 2014, and March 2020, within the study registered with ClinicalTrials.gov, NCT02078804. Swedish population registry data on educational level, household income, country of birth, and marital status were linked to each 60-year-old man and woman who had been randomised to two rounds of FIT 2 years apart (n = 60,123) or once-only PCOL (n = 30,390). Furthermore, we geo-coded each study individual to his/her residential area and assessed neighbourhood-level data on deprivation, proportion of non-Western immigrants, population density, and average distance to healthcare center for colonoscopy. We estimated adjusted associations of each covariate with the colonoscopy attendance proportion out of all invited to respective arms; ie, the preferred outcome for addressing health equity. In the FIT arm, the test uptake and the colonoscopy uptake among the test positives were considered as the secondary outcomes. Findings: We found a marked socioeconomic gradient in the colonoscopy attendance proportion in the PCOL arm (adjusted odds ratio [95% credibility interval] between the groups categorised in the highest vs. lowest national quartile for household income: 2·20 [2·01–2·42]) in parallel with the gradient in the test uptake of the FIT × 2 screening (2·08 [1·96–2·20]). The corresponding gradient in the colonoscopy attendance proportion out of all invited to FIT was less pronounced (1·29 [1·16–1·42]), due to higher proportions of FIT positives in socioeconomically disadvantaged groups. Interpretation: The unintended risk of exacerbating inequalities in health by organised colorectal cancer screening may be higher with a PCOL strategy than a FIT strategy, despite parallel socioeconomic gradients in uptake. Funding: This work was supported by the Swedish Cancer Society under Grant 20 0719. CB and US provided economic support from the Swedish Research Council for Health, Working life, and Welfare under Grant 2020–00962.
