- BACKGROUND: Previous studies on hepatitis C cascade of care have been mainly focused on diagnosis and treatment rate, while less attention has been given to patients lost to follow-up (LTFU) after diagnosis. Analyses of this latter issue on population level are missing.AIMS: In this nationwide study of people with HCV, we aimed to estimate the proportion LTFU after HCV diagnosis, characterize them, and analyze their other healthcare contacts.METHODS: Patients diagnosed with chronic HCV in the Swedish National Patient register during 2001-2011 and still alive December 31, 2013, were included. The number of cured patients without need of follow-up was estimated. Visits to HCV specialist care during 2012-2013 were analysed. For those LTFU, other specialist care contacts were studied.RESULTS: In total 29,217 patients were included, with 24,733 with need of HCV care. 61% (n=15,007) of them were LTFU from HCV care in 2012-2013 and 58% did not attend HCV care during the second year after HCV diagnosis. The departments of surgery/orthopedic or psychiatry/dependency were the most common other non-primary healthcare contacts. Predictors for LTFU were young age, male sex, low education, presence of psychiatric/dependency diagnosis, unmarried, and longer duration since diagnosis of HCV.CONCLUSIONS: This study showed that almost two-thirds of patients were LTFU after HCV diagnosis, with frequent occurrence early after diagnosis. Efforts to link patients back to HCV care, in combination with early and easy access to HCV treatment and harm reduction, are necessary to reach the HCV elimination goal.

- BACKGROUND:Survivin regulates cell division and inhibits apoptosis. Liver regeneration is a complex process involving both proliferation and apoptosis. The role of survivin is not well elucidated and no data exist in humans.METHODS: Seventy per cent liver resection was used to investigate liver regeneration in rats. Survivin was identified by means of reverse transcriptase polymerase chain reaction, Western blotting and immunohistochemistry. Proliferation and apoptosis were quantified. Liver biopsies from 33 patients who underwent living donor liver transplantation were used to study survivin immuno-expression, proliferation and apoptosis within the first 17 days after transplantation. Seven healthy donors served as controls.RESULTS:Survivin transcript and protein were significantly upregulated in rat hepatocytes after 24-72 h during regeneration and showed a significant correlation with proliferation but not with apoptosis. In humans, survivin was nearly absent in donor and reperfused liver tissue but increased significantly 5-7 days after transplantation and correlated with proliferation but not with apoptosis.CONCLUSIONS: Survivin is upregulated in human and rodent liver regeneration and correlates with proliferation, suggesting an association of survivin and cell division.

- Background and Aims: The presence of advanced hepatic fibrosis is the prime marker for the prediction of liver-related complications in non-alcoholic fatty liver disease (NAFLD). Blood-based non-invasive tests (NITs) have been developed to evaluate fibrosis and identify patients at risk. Current guidelines propose monitoring the progression of NAFLD using repeated NITs at 2-3-year intervals. The aim of this study was to evaluate the association of changes in NITs measured at two time points with the progression of NAFLD.Methods. We retrospectively included NAFLD patients with NIT measurements in whom the baseline hepatic fibrosis stage had been assessed by biopsy or transient elastography (TE). Subjects underwent follow-up visits at least 1 year from baseline to evaluate the progression of NAFLD. NAFLD progression was defined as the development of end-stage liver disease or fibrosis progression according to repeat biopsy or TE. The following NITs were calculated at baseline and follow-up: Fibrosis-4 (FIB-4), NAFLD fibrosis score (NFS), aspartate aminotransferase to platelet ratio index (APRI) and dynamic aspartate-to-alanine aminotransferase ratio (dAAR).Results: One hundred and thirty-five patients were included with a mean follow-up of 12.6 +/- 8.5 years. During follow-up, 41 patients (30%) were diagnosed with progressive NAFLD. Change in NIT scores during follow-up was significantly associated with disease progression for all NITs tested except for NFS. However, the diagnostic precision was suboptimal with area under the receiver operating characteristics 0.56-0.64 and positive predictive values of 0.28-0.36 at sensitivity fixed at 90%.Conclusions: Change of FIB-4, NFS, APRI, and dAAR scores is only weakly associated with disease progression in NAFLD. Our findings do not support repeated measurements of these NITs for monitoring the course of NAFLD.

- Background: Population-based studies on the epidemiology of primary sclerosing cholangitis (PSC) are sparse. Aims: To investigate mortality and risk of cancer, and to identify risk factors for hepatobiliary cancer and the combined end-point liver related death or liver transplantation (OLT) in a population-based PSC cohort in Västra Götaland, Sweden. Methods: Primary sclerosing cholangitis cases were identified in diagnostic registries. Case validation and follow up was provided through individual review of case files and linkage to the Swedish Cancer and Cause of Death registries. Standardized mortality ratio (SMR) and standardized incidence ratio (SIR) for cancer were calculated in relation to the background population. Cox's proportional hazards analysis was used to calculate crude and adjusted relative risks (RRs). Results: A total of 199 PSC patients were identified between 1992 and 2005. SMR in the PSC cohort was 4.20 (95% confidence interval (CI), 3.01–5.69). SIR for hepatobiliary cancer, cholangiocarcinoma and colorectal cancer were 177 (110–271), 868 (505–1390) and 2.87 (0.33–10.4) respectively. Age (RR=1.25 (1.01–1.53) per decade), female gender (RR=2.01 (1.09–3.72)), cholangitis (RR=2.56 (1.20–5.64)) and bilirubin (RR=3.95 (1.96–10.75) highest vs lowest quartile) were associated with the risk of liver related death or OLT. Age was associated with the risk of hepatobiliary cancer (RR 1.40 (1.01–1.95) per decade). Conclusions: Primary sclerosing cholangitis was associated with a four-fold increase in mortality in this population-based study. In accordance with previous studies, the risk of hepatobiliary cancer was dramatically increased. However, the increased risk of colorectal cancer reported in previous studies could not be confirmed.

- BACKGROUND & AIMS: Evidence for the benefit of scheduled imaging for early detection of hepatobiliary malignancies in primary sclerosing cholangitis (PSC) is limited. We aimed to compare different follow-up strategies in PSC with the hypothesis that regular imaging improves survival.METHODS: We collected retrospective data from 2,975 PSC patients from 27 centers. Patients were followed from the start of scheduled imaging or in case of clinical follow-up from January 1, 2000, until death or last clinical follow-up alive. The primary endpoint was all-cause mortality.RESULTS: A broad variety of different follow-up strategies were reported. All except one center used regular imaging, ultrasound (US) and/or magnetic resonance imaging (MRI). Two centers used scheduled ERCP in addition to imaging for surveillance purposes. The overall HR (CI95%) for death, adjusted for sex, age and start year of follow-up, were 0.61 (0.47-0.80) for scheduled imaging with and without ERCP; 0.64 (0.48-0.86) for US/MRI and 0.53 (0.37-0.75) for follow-up strategies including scheduled ERCP. The lower risk of death remained for scheduled imaging with and without ERCP after adjustment for cholangiocarcinoma (CCA) or high-grade dysplasia as a time-dependent covariate, HR 0.57 (0.44-0.75). Hepatobiliary malignancy was diagnosed in 175 (5.9%) of the patients at 7.9 years follow-up. Asymptomatic patients (25%) with CCA had better survival if scheduled imaging had been performed.CONCLUSIONS: Follow-up strategies vary considerably across centers. Scheduled imaging was associated with improved survival. Multiple factors may contribute to this result including early tumor detection and increased endoscopic treatment of asymptomatic benign biliary strictures.

- BACKGROUND & AIMS: In 2014, the burden of hepatitis C virus (HCV) in Sweden was evaluated, to establish a baseline and inform public health interventions. Considering the changing landscape of HCV treatment, prevention, and care, and in light of the COVID-19 pandemic, this analysis seeks to evaluate Sweden's progress toward the WHO elimination targets and identify remaining barriers.METHODS: The data used for modeling HCV transmission and disease burden in Sweden were obtained through literature review, unpublished sources, and expert input. A dynamic Markov model was employed to forecast population sizes and incidence of HCV through 2030. Two scenarios ("2019 Base" and "WHO Targets") were developed to evaluate Sweden's progress toward HCV elimination.RESULTS: At the beginning of 2019, there were 29,700 (95% UI: 19,300 - 33,700) viremic infections in Sweden. Under the base scenario, Sweden would achieve and exceed the WHO targets for diagnosis, treatment, and liver-related death. However, new infections would decrease by less than 10%, relative to 2015. Achieving all WHO targets by 2030 would require 1) expanding harm reduction programs to reach more than 90% of PWID and 2) treating 90% of HCV+ PWID engaged in harm reduction programs and ≥7% of PWID not involved in harm reduction programs, annually by 2025.CONCLUSIONS: It is of utmost importance that Sweden, and all countries, find sustainability in HCV programs by broadening the setting and base of providers to provide stability and continuity of care during turbulent times.
