SummaryBackground and AimsPSC is an autoimmune biliary inflammatory disorder that is often associated with inflammatory bowel disease (IBD), with 50%‐75% of patients with PSC having coexisting IBD, most commonly ulcerative colitis. Currently, no medical therapies have been shown to improve the disease course or slow its progression. However, ongoing research has resulted in a growing interest in the use of antibiotics for treatment of PSC, of which vancomycin is the most studied. In this review, we summarise the current evidence on the use of vancomycin in PSC and comment on future research areas of interest.MethodsA comprehensive PUBMED and EMBASE literature search for articles on vancomycin, PSC, therapeutic options and microbiome was performed.ResultsTwo randomised clinical trials, three case series and two case reports were included in the study. These include uncontrolled data from at least 98 patients that include promising improvements in biochemistry and imaging. Optimal dosing regimens are unclear.ConclusionVancomycin is one of the most studied antibiotics used in the treatment of PSC with promising results. There is not currently sufficient evidence to support treatment recommendations. Further research is needed to establish if vancomycin is a PSC treatment.
Surveillance for hepatobiliary cancers in patients with primary sclerosing cholangitis
Primary sclerosing cholangitis (PSC) is a risk factor for cholangiocarcinoma (CCA) and gallbladder carcinoma (GBCa). Surveillance for GBCa is recommended, but the clinical utility of surveillance for other hepatobiliary cancers (HBCa) in PSC, namely CCA and hepatocellular carcinoma (HCC), remains unclear. We aimed to determine whether surveillance is associated with better survival after diagnosis of HBCa in patients with PSC. Medical records of PSC patients seen at the Mayo Clinic Rochester from 1995 to 2015 were reviewed. Patients were included if they had ≥1 year of follow‐up and developed HBCa. Patients were categorized according to their surveillance status (abdominal imaging, carbohydrate antigen 19‐9, and alpha‐fetoprotein). The primary endpoints were HBCa recurrence, HBCa‐related death, and all‐cause mortality. Overall survival was assessed by the Kaplan‐Meier survival method; HBCa‐related survival was assessed using competing risk regression. Tests of significance were two‐tailed, and a P value <0.05 was considered statistically significant. From 1995 to 2015, a total of 79 of 830 PSC patients were diagnosed with HBCa. Cumulative follow‐up was 712 and 283 person‐years pre‐ and post‐HBCa diagnosis, respectively. Seventy‐eight percent of patients (54/79) developed CCA, 21% (17/79) HCC, 6% (5/79) GBCa, 3% (2/79) both CCA and HCC, and 1% (1/79) both HCC and GBCa. Fifty‐one percent (40/79) were under HBCa surveillance, and 49% (39/79) were not. Patients in the surveillance group had significantly higher 5‐year overall survival (68% versus 20%, respectively; P < 0.001) and significantly lower 5‐year probability of experiencing an HBCa‐related adverse event (32% versus 75%, respectively; P < 0.001) compared with the no‐surveillance group. Conclusion: This study demonstrates that HBCa surveillance significantly improves outcomes, including survival, in patients with PSC. (Hepatology 2018;67:2338‐2351).
SummaryBackgroundWith recent advances in the management of chronic liver disease and its complications, the long‐term survival in cirrhosis has improved. Therefore, the number of individuals who will spend a significant proportion of their life with end‐stage liver disease (ESLD) may continue to rise. Thus, more attention to quality of life (QOL) and its integration with traditional clinical endpoints is needed.AimsRecently, there have been many studies looking at treatment outcomes and their impact on the QOL in patients with ESLD. The aim of this review was to summarise and compare the insights gained from these intervention studies and to make concise recommendations to further promote and improve QOL in this patient population.MethodsA literature search was conducted using PubMed and Web of Science. Search terms “Quality of life” “Cirrhosis” and “end‐stage liver disease” were used as MeSH terms or searched in the title of the article.ResultsThese studies uniformly show significant improvement in health‐related QOL (HRQOL) with management of malnutrition, hepatic encephalopathy and ascites. Thus, early recognition and management of these complications are keys to better serve our patients. Early involvement of palliative care also leads to improved quality of end‐of‐life care.ConclusionsComplications of cirrhosis including malnutrition, encephalopathy, ascites and variceal bleeding lead to a decrease in HRQOL. Assessment of HRQOL has an important implication for the patient. The findings of this review illuminate the importance of using consistent tools to accurately assess QOL in patients with ESLD.
Old and new treatments for primary biliary cholangitis
Abstract Primary biliary cholangitis (formerly primary biliary cirrhosis) is a rare progressive cholestatic liver disease, whose hallmark features include a persistently elevated alkaline phosphatase level, presence of anti‐mitochondrial antibodies and characteristic histology. Since 1998, ursodeoxycholic acid ( UDCA ), a bile acid, has been the only available therapeutic agent. Primary biliary cholangitis is associated with the development of end‐stage liver disease, increased morbidity and mortality. UDCA has been shown to improve serum biochemistries, histology and delay the need for liver transplantation. The clinical issue is that approximately 25%‐40% of patients do not respond to this standard therapy. In recent years, many trials have investigated alternative and adjunctive treatments, leading to the recent approval of obeticholic acid, an analogue of chenodeoxycholic acid, which has shown significant and sustained reductions in alkaline phosphatase levels in combination with UDCA . Obeticholic acid has rapidly been embraced as a new agent to improve the biochemical profile in refractory patients, in addition to being approved for use as monotherapy in patients who cannot tolerate UDCA . There are several other studies and targets which are being investigated. This review is intended to highlight the benefits of UDCA , educate the reader on the newly available obeticholic acid, and to summarize the many ongoing trials and therapeutic targets being investigated in attempts to control and cure primary biliary cholangitis.
A multicenter study to define sarcopenia in patients with end‐stage liver disease
Sarcopenia is associated with increased wait‐list mortality, but a standard definition is lacking. In this retrospective study, we sought to determine the optimal definition of sarcopenia in end‐stage liver disease (ESLD) patients awaiting liver transplantation (LT). Included were 396 patients newly listed for LT in 2012 at 5 North American transplant centers. All computed tomography scans were read by 2 individuals with interobserver correlation of 98%. Using image analysis software, the total cross‐sectional area (cm 2 ) of abdominal skeletal muscle at the third lumbar vertebra was measured. The skeletal muscle index (SMI), which normalizes muscle area to patient height, was then calculated. The primary outcome was wait‐list mortality, defined as death on the waiting list or removal from the waiting list for reasons of clinical deterioration. Sex‐specific potential cutoff values to define sarcopenia were determined with a grid search guided by log‐rank test statistics. Optimal search methods identified potential cutoffs to detect survival differences between groups. The overall median SMI was 47.6 cm 2 /m 2 : 50.0 in men and 42.0 in women. At a median of 8.8 months follow‐up, mortality was 25% in men and 36% in women. Patients who died had lower SMI than those who survived (45.6 versus 48.5 cm 2 /m 2 ; P < 0.001), and SMI was associated with wait‐list mortality (hazard ratio, 0.95; P < 0.001). Optimal search method yielded SMI cutoffs of 50 cm 2 /m 2 for men and 39 cm 2 /m 2 for women; these cutoff values best combined statistical significance with a sufficient number of events to detect survival differences between groups. In conclusion, we recommend that an SMI < 50 cm 2 /m 2 for men and < 39 cm 2 /m 2 for women be used to define sarcopenia in patients with ESLD awaiting LT.
