Abstract
Primary sclerosing cholangitis is a chronic cholestatic liver disease characterized by inflammation and fibrosis of intra- and/or extrahepatic bile ducts leading to the formation of multifocal strictures alternated to bile duct dilatations. The diagnosis of the most common subtype of the disease, the large duct PSC, is based on the presence of elevation of cholestatic indices, the association of typical cholangiographic findings assessed by magnetic resonance cholangiography and the exclusion of causes of secondary sclerosing cholangitis. Liver biopsy is not routinely applied for the diagnosis of large duct PSC but is mandatory in the case of suspicion of small duct PSC or overlap with autoimmune hepatitis.

Abstract
Vitamin D deficiency has been linked with adverse events in various liver diseases. The present study aimed to recognize the association between severe vitamin D deficiency and disease progression, hepatobiliary malignancies, liver-related mortality, and the need for liver transplantation in primary sclerosing cholangitis (PSC). Patients with a diagnosis of PSC (n = 354), followed by the autoimmune liver disease clinic at the University of Alberta, were included. Patients with vitamin D levels < 25 nmol/L were defined as severely deficient. Univariate and multivariate analyses were conducted using the Cox proportional hazards regression models. The mean vitamin D level was 59 ± 2 nmol/L, and 63 patients (18%) had a severe vitamin D deficiency. Patients with a severe vitamin D deficiency were 2.5 times more likely to experience hepatobiliary malignancies (HR 2.55, 95% CI, 1.02-6.40, p = 0.046). A severe vitamin D deficiency at diagnosis (HR 1.82, 95% CI, 1.05-3.15, p = 0.03) and persistent deficiencies over time (HR 2.26, 95% CI, 1.17-4.37, p = 0.02) were independently associated with a higher risk of poor clinical liver outcomes. A severe vitamin D deficiency at diagnosis and persistent deficiency at longitudinal assessments were associated with liver-related mortality or the need for liver transplantation.

Abstract
Alagille syndrome (ALGS) is a rare, debilitating inheritable disease that is associated with refractory pruritus due to chronic cholestasis. The following systemic review and meta-analysis presents the latest evidence for ileal bile acid transport (IBAT) blockers in AGLS patients in order to improve their efficacy. This study adhered to PRISMA 2020 Statement guidelines. A systematic search of PubMed/MEDLINE, Web of Science, Scopus, and the Cochrane library was conducted from inception until 23 October 2022. A combination of the following keywords was used: Alagille syndrome, therapeutics, treatment, therapy. Meta-analytical outcomes included effect directions of end-line changes in serum bile acids (sBAs), Itch Scale scores (ItchRO), Multidimensional Fatigue Scale scores, pediatric quality of life (QL), alanine aminotransferase (ALT), and total bilirubin. A total of 94 patients across four trials were enrolled and received maralixibat, odevixibat, or a placebo. There was a significant reduction in ItchRO scores by 1.8 points, as well as in sBAs by 75.8 μmol/L. Both the Multidimensional Fatigue Scale and Pediatric QL scale were also improved by 11.4 and 8.3 points, respectively. However, ALT levels were raised by 40 U/L. The efficacy of IBAT inhibitors across current trials was noted. Future trials may focus on the optimization of dosing regimens, considering gastrointestinal side effects and drug-induced ALT elevation in AGLS patients.

Abstract
Progressive family intrahepatic cholestasis (PFIC) is an autosomal recessive disease that causes chronic cholestasis. It is associated with pathogenic variants in genes that encode proteins involved in bile secretion to canaliculus from hepatocytes. In this study, we present a 16-year-old boy who presented with severe pruritus and cholestatic jaundice. All possible infectious etiologies were negative. A liver biopsy was consistent with intrahepatic cholestasis and portal fibrosis. DNA was isolated from a peripheral blood sample, and whole exome sequencing was performed. A novel c.3484G > T/p.Glu162Ter variant in the ABCB11 gene and a c.208G> A/p.Asp70Asn variant in the ATP8B1 gene were detected. Despite traditional treatment, the patient's recurrent severe symptoms did not improve. The patient was referred for a liver transplantation. This novel c.3484G > T/p.Glu162Ter variant is associated with a severe and recurrent presentation, and the two compound variants could explain the severity of PFIC.

Abstract
BACKGROUND Patients with chronic intestinal failure (CIF) often develop cholestatic liver injury, which may lead to liver failure and need for organ transplantation. OBJECTIVES The aim of this study was to investigate whether citrulline (CIT) and the enterokine fibroblast growth factor 19 (FGF19) are associated with chronic cholestasis and survival in adult CIF patients, and to develop a risk score to predict their survival. METHODS We studied 135 adult CIF patients on intravenous supplementation (>3 mo). Associations of plasma CIT and FGF19 with chronic cholestasis and survival were estimated by logistic and Cox regression models. A predictive risk score was developed and validated internally. RESULTS Patients with chronic cholestasis (17%) had a reduced 5-y survival rate compared with patients without chronic cholestasis (38% and 62%, respectively). In multivariable analysis, low FGF19, low CIT, and female sex were associated with chronic cholestasis. Patients with low rather than high CIT or FGF19 also had reduced 5-y survival rates (29% compared with 69%; 54% compared with 66%, respectively). Risk factors identified in multivariable analysis of survival were low FGF19 (HR: 3.4), low CIT (HR: 3.3), and number of intravenous infusions per week (HR: 1.4). These 3 predictors were incorporated in a risk model of survival termed Model for End-Stage Intestinal Failure (MESIF) (C-statistic 0.78). The 5-y survival rates for patients with MESIF scores of 0 to <20 (n = 47), 20-40 (n = 75), and >40 (n = 13) were 80%, 58%, and 14%, respectively. CONCLUSIONS CIT and FGF19 predict chronic cholestasis and survival in this cohort of adult CIF patients, and the derived MESIF score is associated with their survival. Pending external validation, the MESIF score may help to identify patients for closer clinical monitoring or earlier referral to intestinal transplantation centers.

Abstract
BACKGROUND & AIMS Ursodeoxycholic acid (UDCA) is the standard treatment for primary biliary cirrhosis (PBC) but excellent response is not observed in all cases. Since potential favourable effects of fibrates have been reported in short series with inconclusive results, we have carried out a pilot study to analyse the effects of bezafibrate in patients with suboptimal response to UDCA. METHODS Thirty women (age 52.3 ± 2.3 years) treated with UDCA and abnormal alkaline phosphatase (AP) levels received bezafibrate (400 mg/d) for 1 year. Changes were measured every 3 months during the study period of 12 months, 3 months after discontinuation and 3 months after resuming bezafibrate. RESULTS Two patients discontinued the treatment after few days, three at 6 and one at 9 months. Bezafibrate treatment resulted in a significant decrease in AP as early as 3 months. Normalization or decrease of AP below 1.5 times normal levels was observed in 13 and 4 patients respectively. There was also a significant decrease in γ-glutamyl transferase and alanine aminotransferase, cholesterol and triglyceride levels. Bezafibrate treatment resulted in significant improvement of pruritus. A rebound in liver biochemistries and pruritus occurred upon drug discontinuation, changes which improved again after resuming bezafibrate. Response to bezafibrate was associated with lower liver stiffness and severity of cholestasis. No severe adverse effects were observed. CONCLUSIONS Combination treatment of bezafibrate and UDCA is associated with marked decrease or normalization of alkaline phosphatase as early as 3 months in patients with PBC. Better biochemical response was observed in patients with early disease and lower cholestasis.

Abstract
The autoimmune nature of primary biliary cirrhosis (PBC) is well established. We tested the hypothesis that fetal microchimerism indicated by the persistence of circulating fetal cells in women years after pregnancy might contribute to the aetiopathogenesis of PBC through a graft-versus-host-like response. We extracted DNA from the peripheral blood cells of 36 women carefully selected from 173 consecutive PBC patients, who were matched with 36 healthy women by age, age of last son, and number of children. Both patients and controls had to have male offspring, and no history of miscarriages or blood transfusions; they could not be twins. We tested all of the samples for the presence of two specific Y-chromosome sequences (SY154 and SRY) by amplifying DNA in a nested polymerase chain reaction. Y-chromosome-specific DNA was detected in the peripheral blood cell DNA of 13 (36%) of the 36 women with PBC and in 11 (31%) of the 36 healthy controls. The two groups of PBC patients with and without male DNA sequences were similar in terms of their clinical, biochemical, and serological features. Y-chromosome sequences were found in three of the four PBC women with associated systemic sclerosis. All of the 24 Y-positive samples contained SY154 sequences, but only three PBC patients and six controls showed the presence of both SY154 and SRY sequences. This discrepancy may suggest that not only fetal cells but also fragments of fetal DNA are present in maternal circulation. Overall, our data do not support the hypothesis that fetal microchimerism plays a significant role in the onset or progression of PBC.
