Health Care Utilization and Costs for Patients With End-Stage Liver Disease Are Significantly Higher at the End of Life Compared to Those of Other Decedents.

BACKGROUND & AIMS: Patients with end-stage liver disease (ESLD) have progressively complex medical needs. However, little is known about their end-of-life health care utilization or associated costs. We performed a population-based study to evaluate the end-of-life direct utilization and costs for patients with ESLD among health care sectors in the province of Ontario. METHODS: We used linked Ontario health administrative databases to conduct a population-based retrospective cohort study of all decedents from April 1, 2010, through March 31, 2013. Patients with ESLD were compared with patients without ESLD with regard to total health care utilization and costs in the last year and last 90 days of life. RESULTS: The median age at death was significantly lower for ESLD decedents (65 y; interquartile range, 56-75 y) than for individuals without ESLD (80 y; interquartile range, 68-88 y). The median cost in the last year of life was significantly greater for patients with ESLD ($51,235 vs $44,456 without ESLD) (P < .001). Median ESLD end-of-life care costs also significantly exceeded those associated with 4 of the 5 most resource-intensive chronic conditions ($69,040 for ESLD vs $59,088 for non-ESLD) (P < .001). Cost differences were most pronounced in the final 90 days of life. During this period, patients with ESLD spent 4.7 more days in the hospital (95% CI, 4.3-5.1 d) than patients without ESLD (P < .0001), had significantly higher odds of dying in an institutional setting (odds ratio, 1.8; 95% CI, 1.7-1.9) (P < .0001), and incurred an additional $4201 in costs (95% CI, $3384-$5019; P < .0001). CONCLUSIONS: In a population-based study in Canada, we found that patients with ESLD incur significantly higher end-of-life care costs than decedents without ESLD, predominantly owing to increased time in the hospital during the final 90 days of life.

The Palliative Management of Refractory Cirrhotic Ascites Using the PleurX (©) Catheter.

Background. Treatment options are limited for patients with refractory cirrhotic ascites (RCA). As such, we assessed the safety and effectiveness of the PleurX catheter for RCA. Methods. A retrospective analysis was performed on all patients with RCA who have undergone insertion of the PleurX catheter between 2007 and 2014 at our clinic. Results. Thirty-three patients with RCA were included in the study; 4 patients were lost to follow-up. All patients were still symptomatic despite bimonthly large volume paracentesis and were not candidates for TIPS or PV shunt. Technical success was achieved in 100% of patients. The median duration the catheter remained in situ was 117.5 days, with 95% CI of 48-182 days. Drain patency was maintained in 90% of patients. Microorganisms consistent with spontaneous bacterial peritonitis (SBP) from a catheter source were isolated in 38% of patients. The median time to infection was 105 days, with 95% CI of 34-233 days. All patients were treated for SBP successfully with antibiotics. Conclusion. Use of the PleurX catheter for the management of RCA carries a high risk for infection when the catheter remains in situ for more than 3 months but has an excellent patency rate and did not result in significant renal injury.

Adult liver transplant survey: policies towards eligibility criteria in Canada and the United States 2007.

GOALS: To assess the current practice patterns of liver transplant centres in Canada and the USA regarding transplant eligibility. BACKGROUND: Liver transplantation is an evolving field and today remains the only life-sustaining treatment for end-stage liver disease. Issues of allocation and transplant eligibility are important factors in the ethical practice of medicine. STUDY: Questionnaires were mailed to liver transplant programme directors in Canada and the USA inquiring about current practices regarding recipient eligibility. RESULTS: This study demonstrates that there is consensus in the use of other eligibility criteria, including non-compliance, social status, abstinence from alcohol and methadone and cocaine use. Interestingly, literature is lacking to support the use of these parameters as eligibility criteria with the exception of alcohol. There is a lack in consensus regarding marijuana use, human immunodeficiency virus status, ability to accept blood transfusions and prisoner status. The literature suggests that liver transplantation in select patients who refuse blood transfusions results in good outcomes. CONCLUSIONS: Important decisions regarding transplant eligibility still have to be made empirically in the absence of scientific literature about various social issues. While consensus among transplant programmes is useful, it is important that we continue to use the evidence in the literature to revise these eligibility criteria, keeping in mind ethical principles applied to the access and allocation of a scarce resource.

Acute hepatitis C in a contemporary US cohort: modes of acquisition and factors influencing viral clearance.

BACKGROUND: Acute hepatitis C virus (HCV) infection is often asymptomatic; thus, its epidemiology and natural history are difficult to define. METHODS: Acute HCV infection was identified on the basis of HCV seroconversion within 1 year (n=45), new anti-HCV seropositivity with clinical acute hepatitis (n=21), or HCV strain sequencing after an iatrogenic exposure (n=1). Risk factors were assessed with a baseline questionnaire, and participants were followed up prospectively with serial measurement of viral loads. RESULTS: Of 67 persons with acute HCV infection, most were asymptomatic (64%) and injection drug users (66%). Thirteen had an unknown mode of transmission; of these, 11 reported high-risk sexual behavior. Ten acquired acute HCV infection within 3 months of an iatrogenic exposure; 3 had confirmed iatrogenic infection, and 4 had no other risk factors identified. The spontaneous viral clearance rate after 6 months of infection was 18% (95% confidence interval, 11%-31%). The rate of viral clearance varied significantly by sex (34% vs. 3% for women vs. men; P<.001). CONCLUSIONS: High-risk sexual or iatrogenic exposures may be important contemporary risk factors for HCV infection. The spontaneous viral clearance rate (18%) in this contemporary study was similar to that reported for past studies of transfusion-associated HCV infection. Women were more likely to clear acute HCV infection than men.

Pathophysiologic observations and histopathologic recognition of the portal hyperperfusion or small-for-size syndrome.

In an attempt to more completely define the histopathologic features of the portal vein hyperperfusion or small-for-size syndrome (PHP/SFSS), we strictly identified 5 PHP/SFSS cases among 39 (5/39; 13%) adult living donor liver transplants (ALDLT) completed between 11/01 and 09/03. Living donor segments consisting of 3 right lobes, 1 left lobe, and 1 left lateral segment, with a mean allograft-to-recipient weight ratio (GRWR) of 1.0 +/- 0.3 (range 0.6 to 1.4), were transplanted without complications, initially, into 6 relatively healthy 25 to 63-year-old recipients. However, all recipients developed otherwise unexplained jaundice, coagulopathy, and ascites within 5 days after transplantation. Examination of sequential posttransplant biopsies and 3 failed allografts with clinicopathologic correlation was used in an attempt to reconstruct the sequence of events. Early findings included: (1) portal hyperperfusion resulting in portal vein and periportal sinusoidal endothelial denudation and focal hemorrhage into the portal tract connective tissue, which dissected into the periportal hepatic parenchyma when severe; and (2) poor hepatic arterial flow and vasospasm, which in severe cases, led to functional dearterialization, ischemic cholangitis, and parenchymal infarcts. Late sequelae in grafts surviving the initial events included small portal vein branch thrombosis with occasional luminal obliteration or recanalization, nodular regenerative hyperplasia, and biliary strictures. These findings suggest that portal hyperperfusion, venous pathology, and the arterial buffer response importantly contribute to early and late clinical and histopathologic manifestations of the small-for-size syndrome.

Budd-Chiari syndrome: in evolution.

Budd-Chiari syndrome (BCS) is a rare but potentially life-threatening disorder caused by hepatic venous obstruction, distinct from cardiac causes of hepatic congestion or sinusoidal obstruction syndrome (formerly known as veno-occlusive disease). BCS may be classified as primary or secondary, depending on the underlying process. Most cases of primary BCS are due to an underlying hypercoagulable disorder. A high index of suspicion is required to make the diagnosis. In most case series, chronic, indolent cases of BCS are more common than acute presentations. Doppler ultrasound, magnetic resonance imaging (MRI), and direct venography are useful in confirming the diagnosis. Systemic anticoagulation should be started expeditiously, as long as there are no contraindications. The use of systemic thrombolysis remains controversial. However, thrombolysis may prove effective when it is administered locally following hepatic venoplasty with or without stenting. Guidelines for the management of more complex cases and of patients who fail medical management are currently in evolution. Budd-Chiari syndrome (BCS) is potentially life-threatening, depending on the extent and rapidity of hepatic venous obstruction. A high index of suspicion is required to clinch the diagnosis, since BCS may be quite indolent or even asymptomatic. Doppler ultrasound or magnetic resonance imaging (MRI) is usually definitive. Systemic anticoagulation should be offered to all patients, unless contraindicated. The role of thrombolysis in BCS remains controversial, and thus it should be reserved for cases undergoing hepatic decompression via percutaneous angioplasty. Guidelines for the management of cases who fail standard medical management are currently in evolution.

Use of hepatitis B core antibody-positive donors in recipients without evidence of hepatitis B infection: a survey of current practice in the United States.

Because of the current organ shortage, some liver transplant programs have begun to accept marginal organs that previously would have been rejected. An example is the use of donors with evidence of past hepatitis B virus (HBV) infection. To gain insight into the use of hepatitis B core antibody-positive (anti-HBc(+)) donor livers in recipients without evidence of HBV infection, we conducted a survey. Surveys consisting of 12 multiple-choice questions were sent to all 110 liver transplant programs across the United States in mid-2001, and 56 of 110 surveys (51%) could be evaluated. Overall, 32 of 56 programs (57%) indicated they would transplant an anti-HBc(+) liver into a recipient without serological evidence of HBV infection. Of those who would accept an anti-HBc(+) liver, 16 of 27 respondents (59%) indicated knowledge of HBV DNA status would change their protocol; 46% of these respondents would decrease prophylaxis if HBV DNA was negative, 27% would increase prophylaxis if HBV DNA was positive, and 27% would not accept the liver if HBV DNA was positive. Conversely, 9 of 28 respondents (32%) who would not accept an anti-HBc(+) liver stated that knowing HBV DNA status would change their protocol in that they might consider accepting livers if HBV DNA was negative. In conclusion, as of mid-2001, of transplant medical directors in the United States who responded to our survey, 57% would accept an anti-HBc(+) donor liver for an HBV-naïve recipient. Treatment protocols for using these organs varied. Knowledge about HBV DNA status of the donor and/or liver would greatly influence prophylaxis for those accepting anti-HBc(+) donor livers.

Hepatic disease in injection drug users.

A wide variety of infectious diseases affect injection drug users. One of the most common is viral hepatitis. In the United States, hepatitis B affects 1.5 million people, and hepatitis C affects more than 4 million people, many of whom are past or current users of injected drugs. Although the treatment for chronic hepatitis B and hepatitis C has improved, protocols specifically designed for injection drug users, especially given their lifestyle and reportedly low compliance rates, are seriously lacking. These disorders can lead to cirrhosis, hepatocellular carcinoma, and the need for liver transplantation in a sizeable proportion of cases. Therefore, early intervention should be a top priority.

Liver transplantation in mushroom poisoning.

Liver transplantation plays an important role in the treatment of patients with fulminant hepatic failure (FHF). Early determination of prognosis in cases of FHF is important to allow prompt decision-making regarding the need for liver transplantation. Mushroom poisoning is a rare cause of FHF, and as a result, prognostic criteria are not well recognized. It appears that the severity of coagulopathy and encephalopathy predicts a poor outcome, whereas the degree of bilirubin elevation may not. We present a case of FHF related to mushroom poisoning that required liver transplantation. The clinical presentation, medical management, and prognostic criteria in mushroom poisoning are discussed.

Henoch-Schönlein purpura.

Preview As the name implies, Henoch-Schönlein purpura is a vasculitic disease, but it also affects multiple organ systems. Although the exact cause of the disease has not been determined, recent studies have shed some light on its pathogenesis. This article reviews these studies and discusses the various manifestations and possible complications. Two classification systems are also included.
