Hep C–infected livers are safe for transplant

Article Type
Changed

 

– A new analysis shows that hepatitis C–infected livers can be safely transplanted into recipients with no effect on graft survival, retransplantation, or mortality. The work confirms that readily available direct-acting antiviral therapy can protect organ recipients and open a source of organs that is typically overlooked.

The work should encourage both physicians and patients to take a closer look at hepatitis C–infected organs, especially for sicker patients, according to Sonali Paul, MD, who presented the study at the annual meeting of the American Association for the Study of Liver Disease 2018.

“A lot of people have an ethical issue with it because we’re actively transplanting a virus into someone. We’re giving someone a disease. My take on it is that we give people Epstein Barr virus or cytomegalovirus all the time – we just [provide] prophylaxis against it, and we don’t even bat an eye. Hepatitis C can be devastating, but we have totally effective treatments for it,” said Dr. Paul, who is an assistant professor of medicine at the University of Chicago.

She cited one colleague at the University of Chicago who several years ago transplanted an organ that had been passed over 700 times, though times have changed since then. “I think people more and more are doing this practice because we know it’s so successful,” said Dr. Paul.

It’s also cost effective. Another study, presented during the same session by Jag Chhatwal, PhD, assistant professor at Harvard Medical School, Boston, showed that accepting a hepatitis C–positive liver is cost effective in patients with Model for End-Stage Liver Disease (MELD) scores ranging from 22 to 40.

“I think we’re going to find across all organ systems, if we can transplant patients rather than keep them on dialysis or keep them on wait lists, it’s got to be cost effective, especially if you think of the health care–associated costs – like a heart transplant patient waiting on the list in the ICU. That’s a huge health care cost,” said Dr. Paul.

Dr. Paul’s team performed an analysis of the Scientific Registry of Transplant Recipients, including single organ transplants from deceased donors, during 2014-2018. Over that period, the number of transplants from hepatitis C–positive donors to hepatitis C–positive recipients rose from 8 in 2014 to 269, and the number of transplants from hepatitis C–positive donors to hepatitis C–negative recipients rose from 0 to 46.

The researchers compared trends from hepatitis C–negative donors with hepatitis C–negative recipients (n = 11,270), negative donors with positive recipients (n = 4,748), positive donors with negative recipients (n = 87), and positive donors with positive recipients (n = 753). Donor status had no effect on graft survival times at 1 or 2 years, with values ranging from 92.6% (negative to negative) to 94.3% (positive to positive) at 1 year and between 85.7% (positive to negative) and 89.7% (positive to positive) at 2 years.

“For someone who has a MELD score of over 20, who has a declining quality of life and really can’t do anything, I think this is a great opportunity. And most patients are absolutely willing to take these organs. We haven’t had many people say no, especially if they feel poorly,” said Dr. Paul.

She also underscored the importance of ensuring that the patient is informed of the status of the donor liver and the need to complete treatment: “The patient has to know what’s happening, and the hospital has to have a safety net if the insurance doesn’t pay for hepatitis C treatment.”

Risk of cancer in NAFLD is 91% higher than in control subjects

Article Type

The risk of malignancy among patients with nonalcoholic fatty liver disease (NAFLD) is 91% higher than it is among age- and sex-matched control subjects, with gastrointestinal sites being the most commonly affected.

Doug Brunk/MDedge News
Dr. Alina M. Allen

Those are key findings from a community cohort study with up to 21 years of follow-up, which one of the authors, Alina M. Allen, MD, discussed during a press briefing at the annual meeting of the American Association for the Study of Liver Diseases.

“NAFLD is the most common chronic liver disease in the Western world,” said Dr. Allen, a gastroenterologist at the Mayo Clinic, Rochester, Minn. “It affects one in four adults in the U.S. It is related to fat accumulation in the liver in people who are overweight or obese and can lead to cirrhosis and liver-related mortality. However, the most common cause of death in this population is not liver disease but malignancy and cardiovascular disease. There is a paucity of epidemiologic studies of extrahepatic cancer in NAFLD. It is not clear what types of cancers and how much higher their cancer risk is in reference to the general population.”

In an effort to determine the incidence of cancer diagnoses in NALFD, compared with controls, in a U.S. community, Dr. Allen and her colleagues drew from the Rochester Epidemiology Project to evaluate 4,791 adults diagnosed with NAFLD and 14,432 age- and sex-matched control subjects in Olmstead County, Minn., during 1997-2017. The researchers obtained corresponding Surveillance, Epidemiology, and End Results Program (SEER) rates as a quality check and used a regression model to assess the malignancy risk in NAFLD overall and by cancer type, age, sex, and body mass index. They recorded all new diagnoses of cancers that developed in both groups until 2018, for a total possible follow-up of 21 years, and they reported results in incidence rate ratios, a risk estimate similar to hazard ratios.


The mean age of the study population was 53 years, 53% were female, and the mean follow-up was 8 years with a range from 1 to 21 years. New cancers were identified in 16% of subjects with NALFD and in 12% of control subjects. The overall risk of malignancy was 91% higher in NAFLD subjects, compared with control subjects; there were higher rates in the NAFLD subjects for most types of cancers, but the largest increases were in GI cancers. The greatest malignancy risk was for cancer of the liver (RR, 3.24), followed by cancer of the uterus (RR, 2.39), stomach (RR, 2.34), pancreas (RR, 2.09), and colon (RR, 1.75). “Interestingly, the risk of colon cancer increased only in men but not in women,” Dr. Allen said. “These data provide an important hierarchical overview of the top most important malignancy risks associated with NAFLD that the medical community should be aware of.”

When the researchers looked for differences in age at cancer diagnosis between NAFLD and controls, they found that pancreas cancer occurred at a younger age among subjects with NAFLD. They also observed that colon cancer occurred at a younger age in men with NAFLD, but not in women with the disease. “What was most interesting to us was the assessment of cancer risk in NAFLD versus obesity alone,” Dr. Allen said. “Previous studies from the general population have linked obesity to a higher risk of cancer. Whether the presence of fatty liver disease would impact that risk has not been assessed. We showed that obesity is associated with a higher risk of cancer only in those with NAFLD, not in those without. If validated in independent cohorts, these findings could change our understanding of the relationship between obesity and cancer and the importance of screening for NAFLD – not only to risk-stratify liver disease but also for the risk of extrahepatic malignancy.”

Dr. Allen concluded her presentation by noting that findings from large population-based studies such as the Rochester Epidemiology Project “can offer important epidemiologic data regarding the biggest threats to the health of a community,” she said. “Such data increase awareness, enable appropriate counseling, and could inform screening policies. There is a signal in the fact that the GI cancers are increased [in NAFLD]. It’s an interesting signal that needs to be studied further.”

Dr. Allen reported having no financial conflicts.

Chronic liver disease independently linked to increased risk of falls

Article Type

Chronic liver disease (CLD) is independently associated with an increased risk of falls and fall injuries, results from a large study of nationally representative data showed.

Dr. Elliot B. Tapper and Dr. Maria Camila Perez-Matos

“We have previously known that having cirrhosis, for example, is associated with the risk of falling, but we didn’t have any data from a nationally representative sample,” lead study author Maria Camila Pérez-Matos, MD, said in an interview at the annual meeting of the American Association for the Study of Liver Diseases. “What surprised us is that just by having chronic liver disease – any subtype – you’re more likely to fall, and also to have a fracture after you have fallen.”



In an effort to define the association between CLD and fall history and its related injuries, Dr. Pérez-Matos of the division of gastroenterology and hepatology at Beth Israel Deaconess Medical Center, Boston, and her associates examined data from 5,363 subjects aged 60 years and older in the Third National Health and Nutrition Examination Survey, which represents the noninstitutionalized civilian population in the United States. Their outcomes of interest were one or more falls occurring in the previous 12 months and fall-related injuries. The main exposure was definitive CLD, defined by chronic viral hepatitis (hepatitis C RNA or hepatitis B surface antigen), nonalcoholic steatohepatitis (NASH; hepatosteatosis by ultrasound with abnormal transaminases), and alcohol-related liver disease (females consuming more than 7 drinks/week and males consuming 14 drinks/week among, plus having abnormal transaminases). Suspected CLD was defined as having abnormal alanine aminotransferase levels (males greater than 30 IU/L, females greater than 19 IU/L), aspartate aminotransferase levels above 33 IU/L, or alkaline phosphatase levels above 100 IU/L. The researchers used univariate and multivariate logistic regression to examine associations.

The average age of subjects was 70 years, and 59% were female. Of the 5,363 subjects, 340 had definitive CLD. Of these, 234 (69%) had NASH, 85 (25%) had viral hepatitis, and 21 (6%) had alcoholic liver disease. Subjects with definitive CLD were more likely to be female and have diabetes mellitus, a higher body mass index, and physical/functional impairment. Dr. Pérez-Matos and her colleagues found that definitive CLD was associated with a 52% increase in the odds of having a history of falls (odds ratio, 1.52; P = .01). The association remained significant after controlling for age, sex, smoking, race, physical or functional impairment, impaired vision, polypharmacy, and body mass index. The degree of excess falling risk posed by CLD was similar to that of having impaired vision (OR, 1.48; P less than .001).

Of the CLD subtypes, subjects with viral hepatitis had the strongest association with a history of falls (OR, 2.2; P = .001). In addition, definitive CLD was found to have significant association with any physical impairment, even after adjusting for relevant covariates (OR, 1.63; P = .001).

Finally, multivariate logistic regression revealed that both suspected and definitive CLD were associated with injurious falls (OR, 1.40 and OR of 1.67, respectively). “Everyone is interested in preventing falls because of its public health impact, and predictors of falls are relatively limited,” said Elliott B. Tapper, MD, the study’s principal investigator, who is with the division of gastroenterology and hepatology at the University of Michigan, Ann Arbor. “Because chronic liver disease is increasingly common, our data is speaking to a hitherto unknown risk factor: one which if you apply it to other data sets might help figure out why more people are falling. The lesson is, there’s something about chronic liver disease; it’s a sign. If it’s fatty liver disease, it’s a sign that diabetes has taken its toll on the body – its nerves and muscles. There’s something about what’s going on in that person that’s worse than it is for other people. We don’t know cause or effect, but the association is strong and deserves further study, particularly when it comes to determining [which patients] in our clinics are at higher risk and making sure they’re doing physical therapy to prevent falls in the future.”

Dr. Tapper disclosed that she has a career development award from the National Institutes of Health. Dr. Pérez-Matos reported having no monetary conflicts.

The lesson is, there’s something about chronic liver disease; it’s a sign. If it’s fatty liver disease, it’s a sign that diabetes has taken its toll on the body – its nerves and muscles. There’s something about what’s going on in that person that’s worse than it is for other people. We don’t know cause or effect, but the association is strong and deserves further study, particularly when it comes to determining [which patients] in our clinics are at higher risk and making sure they’re doing physical therapy to prevent falls in the future.”

“We have previously known that having cirrhosis, for example, is associated with the risk of falling, but we didn’t have any data from a nationally representative sample,” lead study author Maria Camila Pérez-Matos, MD, said in an interview at the annual meeting of the American Association for the Study of Liver Diseases. “What surprised us is that just by having chronic liver disease – any subtype – you’re more likely to fall, and also to have a fracture after you have fallen.”



In an effort to define the association between CLD and fall history and its related injuries, Dr. Pérez-Matos of the division of gastroenterology and hepatology at Beth Israel Deaconess Medical Center, Boston, and her associates examined data from 5,363 subjects aged 60 years and older in the Third National Health and Nutrition Examination Survey, which represents the noninstitutionalized civilian population in the United States. Their outcomes of interest were one or more falls occurring in the previous 12 months and fall-related injuries. The main exposure was definitive CLD, defined by chronic viral hepatitis (hepatitis C RNA or hepatitis B surface antigen), nonalcoholic steatohepatitis (NASH; hepatosteatosis by ultrasound with abnormal transaminases), and alcohol-related liver disease (females consuming more than 7 drinks/week and males consuming 14 drinks/week among, plus having abnormal transaminases). Suspected CLD was defined as having abnormal alanine aminotransferase levels (males greater than 30 IU/L, females greater than 19 IU/L), aspartate aminotransferase levels above 33 IU/L, or alkaline phosphatase levels above 100 IU/L. The researchers used univariate and multivariate logistic regression to examine associations.

The average age of subjects was 70 years, and 59% were female. Of the 5,363 subjects, 340 had definitive CLD. Of these, 234 (69%) had NASH, 85 (25%) had viral hepatitis, and 21 (6%) had alcoholic liver disease. Subjects with definitive CLD were more likely to be female and have diabetes mellitus, a higher body mass index, and physical/functional impairment. Dr. Pérez-Matos and her colleagues found that definitive CLD was associated with a 52% increase in the odds of having a history of falls (odds ratio, 1.52; P = .01). The association remained significant after controlling for age, sex, smoking, race, physical or functional impairment, impaired vision, polypharmacy, and body mass index. The degree of excess falling risk posed by CLD was similar to that of having impaired vision (OR, 1.48; P less than .001).

Of the CLD subtypes, subjects with viral hepatitis had the strongest association with a history of falls (OR, 2.2; P = .001). In addition, definitive CLD was found to have significant association with any physical impairment, even after adjusting for relevant covariates (OR, 1.63; P = .001).

Finally, multivariate logistic regression revealed that both suspected and definitive CLD were associated with injurious falls (OR, 1.40 and OR of 1.67, respectively). “Everyone is interested in preventing falls because of its public health impact, and predictors of falls are relatively limited,” said Elliott B. Tapper, MD, the study’s principal investigator, who is with the division of gastroenterology and hepatology at the University of Michigan, Ann Arbor. “Because chronic liver disease is increasingly common, our data is speaking to a hitherto unknown risk factor: one which if you apply it to other data sets might help figure out why more people are falling.

FDA approves pembrolizumab for sorafenib-intolerant HCC patients

Article Type
Changed

 

The Food and Drug Administration has approved pembrolizumab (Keytruda) for the treatment of patients with hepatocellular carcinoma who were previously treated with sorafenib.

Approval was based on results of KEYNOTE-224, a single-arm, open-label, multicenter trial evaluating pembrolizumab in a group of 104 patients with hepatocellular carcinoma who were either intolerant to or had disease progression with sorafenib, according to a company press release.

The objective response rate was 17%, with a complete response rate of 1% and a partial response rate of 16%. In responding patients, 89% had a response duration of at least 6 months, and 56% had a response duration of at least 12 months.

Adverse events were generally similar to those seen in trials of patients with melanoma or non–small cell lung cancer, and included pneumonitis, colitis, hepatitis, endocrinopathies, nephritis, severe skin reactions, solid organ transplant rejection, and allogeneic hematopoietic stem cell transplantation complications.

“Hepatocellular carcinoma is the most common type of liver cancer in adults, and while we have seen recent therapeutic advancements, there are still limited treatment options for advanced recurrent disease. Today’s approval of Keytruda is important, as it provides a new treatment option for patients with hepatocellular carcinoma who have been previously treated with sorafenib,” Andrew X. Zhu, MD, lead investigator and director of liver cancer research at Massachusetts General Hospital and professor of medicine at Harvard Medical School, both in Boston, said in the press release.

About 13% of liver transplant recipients affected by PTSD

Article Type
Changed

The prevalence of PTSD among adult liver transplant recipients is about twice that of the general population and on par with other chronic diseases, results from a pilot study suggest.

Meg O'Meara

“Serving the emotional and mental health of these patients is just as important as [improving] liver function and their immunosuppression,” study author Meg O’Meara, NP, said in an interview at the annual meeting of the American Association for the Study of Liver Diseases.

Recent data suggests that patients who undergo significant medical events like solid organ transplantation face a risk of developing PTSD, but limited information exists regarding the psychological effects following adult liver transplantation, said Ms. O’Meara, a nurse practitioner in the division of gastroenterology and hepatology at the University of Colorado at Denver, Aurora. In an effort to determine the prevalence of and risk factors for PTSD in adult liver transplant recipients, she and her associates used the PCL-5 to screen 71 patients seen at the university’s posttransplant clinic from Dec. 1, 2017, to May 31, 2018. The PCL-5 is a validated 20-item questionnaire that corresponds to the DSM-5 symptom criteria for PTSD.

The researchers also collected clinical and demographic information including pretransplant disease severity, history of psychiatric disease, duration of transplant hospitalization, and need for rehospitalization. They used a multivariable regression model to evaluate associations between clinical and demographic variables and a positive screen for PTSD.



The median age of the 71 patients was 58 years; 61% were male. A preexisting diagnosis of depression was present in 25 patients (35%), their mean Model for End-Stage Liver Disease (MELD) score at time of transplant was 31, and their median time from transplant was 1,163 days. In all, nine patients (12.7%) tested positive for PTSD on the PCL-5, and all met criteria for a provisional diagnosis of PTSD based on the DSM-5 criteria. This prevalence is about two times higher than the prevalence of PTSD in the general population (6.7%), comparable with that reported for heart transplant recipients (10.8%) and coronary artery disease (9%), but lower than that reported for ICU patients (38%), HIV patients (35.3%), and in those with Crohn’s disease (19.1%).

On multivariable logistic regression, only three factors were found to be significantly associated with the development of PTSD: younger age at transplant (P = .019), history of depression (P = .008), and a history of PTSD (P less than .001). “What I found surprising was that the MELD score at the time of transplant and the number of readmissions or complications around the time of transplant were not predictive of PTSD,” Ms. O’Meara said.

One possible explanation for the finding of younger age being a predictor of PTSD, she continued, is that younger liver transplant patients may lack certain coping skills, compared with their older counterparts. “Maybe patients who have had more years to deal with their disease are more accepting of it and they learn how to use productive tools to manage it.”

In their abstract, the researchers acknowledged certain limitations of the study, including its cross-sectional design, small sample size, and lack of corresponding pretransplant data.

The researchers reported having no financial disclosures.

Novel acetaminophen hepatotoxicity strategy curbs inflammation

Article Type
Changed

 

– A novel therapeutic strategy shows initial promise in dampening hepatic cell injury in mice caused by overexposure to acetaminophen. The approach relies on a synthetic version of heparan sulfate, which is believed to interfere with recruitment of neutrophils to the site of hepatic injury. That reduces harm caused by inflammation and may offer a longer therapeutic window than N-acetyl cysteine, which is the current standard therapy but is only effective if given within 8 hours of the injury.

The endogenous syndecan-1, which is a heparan sulfate, is also known to act as a native defense mechanism against inflammatory injury to hepatocytes. “It looks like heparan sulfate attenuates inflammatory responses,” said Jian Liu, PhD, during a presentation of his research at the annual meeting of the American Association for the Study of Liver Diseases. Dr. Liu is a professor of chemical biology and medicinal chemistry at the University of North Carolina at Chapel Hill.

The heparan sulfate analogue heparin has long been used as an anticoagulant, of course, which suggests that a novel heparan sulfate has a good chance of also being safe.

Dr. Liu’s team had to identify a heparan sulfate that had a hepatoprotective effect, but a heparan sulfate’s unique biological activity depends on the specific pattern of sulfation on the heparan molecule. Heparans isolated from natural sources are generally a complex mixture, which makes them difficult to study and produce in large enough quantities to be therapeutically useful.

Dr. Liu’s team used a combinatory approach, harnessing various enzymes to produce hundreds of different heparan sulfate variants, and then screened them for hepatoprotective activity. That process identified an 18-chain heparan sulfate with hepatoprotective activity. With an active formula in hand, they could employ the enzymes to create enough of the pure compound to further the research. “It’s probably two to three hundred times more efficient than the traditional chemical synthesis,” said Dr. Liu.

In mice, researchers injected the 18-mer 30 minutes after a hepatotoxic dose of acetaminophen and again after 12 hours. Tissue staining showed less migration of neutrophils, as well as lower concentrations of tumor necrosis factor–alpha. The animals also had lower alanine transferase levels than did the untreated animals, as well as greater survival after 4 days.

The pathological process surrounding acetaminophen overdose involves release of the high mobility group box 1 (HMGB1) protein from necrotic hepatocytes, which in turn binds to the receptor for advanced glycation end-products (RAGE). The HMGB1/RAGE complex then binds to neutrophils, recruiting them to the site of the injury and initiating inflammation.

To better understand the molecule’s role in the pathological process, the researchers studied RAGE knockout mice, and found that the 18-mer had no protective effect in these animals, suggesting that it relies on RAGE for its biological activity.

Heparan sulfates are widely present in the body, which prompted the researchers to investigate their endogenous effect. In the liver, the primary heparan sulfate is syndecan-1. The researchers demonstrated that the molecule is shed from cell surfaces in response to acetaminophen toxicity and that the levels correlate with HMGB1 release.

Dr. Liu believes that syndecan-1 acts as a natural buffer to inflammation, helping to neutralize HMGB1 and limit damage. “The problem is that when the damage is massive, the shed of syndecan-1 is not enough,” said Dr. Liu. He hopes that something like his team’s heparan sulfate 18-mer can be used therapeutically to bolster these endogenous controls and prevent further damage.

The research was funded by Glycan Therapeutics. Dr. Liu founded Glycan, which offers custom-synthesized heparan sulfates and chondroitin sulfates for research purposes.

High rates of prescription opioid, benzodiazepine use observed in chronic liver disease

Article Type
Changed

 

Patients with chronic liver disease are prescribed opioids and benzodiazepines at very high rates, despite risk for adverse consequences because of hepatic metabolism, according to results from a large longitudinal study of national data.

Dr. Monica Konerman

“Middle-aged individuals and those with a background of substance abuse and mental health conditions appear to have highest rates of use and represent populations for which targeted interventions to curb use could be highest yield,” lead study author Monica Konerman, MD, said in an interview in advance of the annual meeting of the American Association for the Study of Liver Diseases.

In an effort to better understand the rates of prescription opioid and benzodiazepine use in chronic liver disease, Dr. Konerman, director of the Michigan Medicine NAFLD Clinic at the University of Michigan, Ann Arbor, and her colleagues drew from the Truven Health Analytics Marketscan databases from 2009 to 2015. They limited the analysis to individuals with drug coverage who had chronic hepatitis C (HCV) without cirrhosis, cirrhosis, congestive heart failure (CHF), or chronic obstructive pulmonary disease (COPD), and examined pharmacy files for outpatient prescriptions.



Dr. Konerman reported data from 210,191 patients with HCV, 79,332 with cirrhosis, 766,840 with CHF, and 1,438,798 with COPD. Their median age was 59 years, and 51% were female. In per person-years, the prevalence of prescription opioid use was 25% among patients with chronic HCV, 53% among patients with cirrhosis, 26% among those with CHF, and 24% among those with COPD. At the same time, in per person-years, the prevalence of benzodiazepine use was 12% among patients with chronic HCV, 21% among patients with cirrhosis, 12% among those with CHF, and 13% among those with COPD. Use of opioids was greatest in adults 40-59 years of age (P less than .001). High-dose opioid use, defined as 100 opioid morphine equivalents per day or greater, occurred in 23% of those with cirrhosis and in 22% of those with HCV.

“The significant increase in rates of use in chronic liver disease, compared to other chronic conditions was remarkable, particularly given that patients with liver disease are at higher risk for adverse consequences of use due to hepatic metabolism of these medications,” Dr. Konerman said.

She went on to acknowledge “inherent limitations to studies that are secondary database analyses that rely on diagnosis codes for categorization of disease with potential for both over and under classification. We also did not capture inpatient prescriptions,” she said.

U.S. death rates from chronic liver disease continue to rise

Article Type
Changed

 

Chronic liver disease mortality continues to rise in the United States, driven largely by a spike in nonalcoholic fatty liver disease (NAFLD), according to results from an analysis of national data.

Dr. Zobair M. Younossi

“I believe it’s all related to a big increase in obesity and type 2 diabetes in this country,” lead study author Zobair M. Younossi, MD, MPH, said in an interview in advance of the annual meeting of the American Association for the Study of Liver Diseases. “Those two risk factors drive NAFLD and its progressive type, nonalcoholic steatohepatitis (NASH). That accounts for at least part of the increase in mortality related to liver disease.”

In an effort to evaluate recent mortality trends in chronic liver disease in the United States, Dr. Younossi and his colleagues drew from National Vital Statistics Data during 2007-2016. They used ICD-10 codes to select mortality data for alcoholic liver disease, chronic hepatitis B and C, iron overload, NAFLD, cirrhosis, and hepatocellular carcinoma. NAFLD cases were defined as those having an ICD-10 code for NAFLD/NASH or an ICD-10 code for “cirrhosis of unknown etiology.” Next, the researchers adjusted age-standardized death rates to the 2000 U.S. Census population and used logistic regression and propensity scores to estimate predictors of chronic liver disease-related deaths.

Dr. Younossi, who chairs the department of medicine at Inova Fairfax Medical Campus, in Falls Church, Va., and his colleagues reported findings from 838,809 chronic liver disease–related deaths during the study period. They found that the age-standardized death rate for chronic liver disease increased from 21.9/100,000 population in 2007 to 24.9/100,000 population in 2016, which translated into an annual percentage change of 1.3% for males and 2.5% for females. Chronic liver disease–related deaths increased with age and were highest among those aged 55-64 years, followed by those aged 65-74 years – an average annual percentage change of 3.4% and 3.1% in each group.



Among chronic liver disease–related deaths, the most common diagnostic etiology was NAFLD (34.7%), followed by alcoholic liver disease (28.8%) and chronic hepatitis C (21.1%). Between 2007 and 2016, death rates increased from 7.6 to 9.0 per 100,000 population for NAFLD (an average annual percentage change of 2.1%) and from 6.1 to 7.9 per 100,000 population for alcoholic liver disease (an average annual percentage change of 3.1%). “What surprised me was that, despite highly effective treatment for HCV, we still have a burden of hepatitis C in this country,” Dr. Younossi said. “It’s still the most common cause of liver disease in the U.S. But it seems like hepatitis C–related liver disease is being replaced quickly by liver disease from nonalcoholic steatohepatitis. This transition between hepatitis C as the most important cause of liver disease and liver mortality to NASH or obesity-related NASH is becoming more rapid than I expected.”

On multivariate analysis, three factors were independently associated with an increased risk of death in NAFLD: the presence of type 2 diabetes (odds ratio, 1.78), cardiovascular disease (OR, 1.07), and renal failure (OR, 1.08).

“One important message from this study is that NASH is very common in the U.S. population,” said Dr. Younossi, who is also a professor of medicine at Virginia Commonwealth University, Richmond. “These patients are underrecognized and underdiagnosed because they are asymptomatic. The second message is that there is a subtype of patients with fatty liver disease – even a subtype of NASH – that can progress to cirrhosis and its complications. We have to pay attention to this silent disease to identify patients who are at risk for progressive liver disease and try to address some of the risk issues, such as tight control of diabetes, obesity, and control of hypertension and hyperlipidemia. Short of that, right now we have very few medical treatments such as vitamin E and pioglitazone recommended for a very selected group. In contrast, there are plenty of new medications that are being developed. The first step in tackling this disease is to identify who the patients are with fatty liver disease who are at risk for bad outcomes and make sure they’re linked to care by a knowledgeable caregiver [who] understands the importance of NASH.”

Dr. Younossi acknowledged certain limitations of the study, including the fact that liver disease diagnoses were based on ICD-10 coding. He disclosed that he is a consultant for Gilead, Intercept, Novo Nordisk, BMS, AbbVie, Viking, Term Quest Diagnostics, Echosens,and Shionogi. He has also received grant/research support from Gilead, Intercept, and BMS.

Norfloxacin might benefit patients with advanced cirrhosis and low ascites fluid protein levels

Benefit is still unclear
Article Type
Changed

Six months of once-daily norfloxacin therapy did not reduce 6-month mortality among patients with Child-Pugh class C cirrhosis who had not recently received fluoroquinolone therapy.

Mortality based on the Kaplan-Meier method was 14.8% in the norfloxacin group versus 19.7% for patients receiving placebo (P = .21). “Norfloxacin, however, appear[ed] to increase survival of patients with low ascites fluid protein concentrations,” wrote Richard Moreau, MD, of Hôpital Beaujon, Paris, and his associates. The results of the multicenter, double-blind trial of 291 patients were published in the December issue of Gastroenterology.

Patients with advanced cirrhosis often develop spontaneous bacterial peritonitis and other severe bacterial infections, with potentially grave outcomes. These are often enteric gram-negative bacteria that cross the intestinal barrier, enter the systemic circulation, and travel to the site of infection.

Long-term fluoroquinolone therapy (typically with norfloxacin) might help prevent these bacterial infections, the translocation of bacterial products, systemic inflammation, and consequent end-organ dysfunction, such as acute kidney disease. However, long-term antibiotic therapy also raises the specter of multidrug resistance, which is especially concerning when it involves a crucial antibiotic class such as fluoroquinolones, the researchers noted. “[In] patients receiving prolonged fluoroquinolone therapy, the development of infections by multidrug resistant bacteria might obscure the beneficial effect of fluoroquinolones on survival,” they added.

Four previous blinded and placebo-controlled trials have investigated fluoroquinolone therapy and mortality patients with cirrhosis, but they were small, usually included mortality only as a secondary outcome, and yielded mixed results. Hence, the researchers enrolled 291 patients with advanced (Child-Pugh class C) cirrhosis from 18 clinical sites in France and randomly assigned them to receive either norfloxacin (400 mg once daily) or placebo for 6 months. Patients were evaluated monthly during treatment and then at 9 months and 12 months. The primary outcome was survival at 6 months.

In a post hoc analysis, the researchers examined cumulative death rates at 6 months after accounting for liver transplantation as a competing risk of death and including survival data for patients who developed spontaneous bacterial peritonitis. Taking this approach, the estimated cumulative rate of death at 6 months was 15.5% (95% confidence interval, 10.1-21.9) in the norfloxacin group and 24.8% (95% CI, 18.1-32.1) in the placebo group, for a hazard ratio of 0.59 (95% CI, 0.35-0.99). Among patients whose ascites fluid levels were less than 15 g/L, the hazard ratio for death at 6 months was 65% lower in the norfloxacin group than in the placebo group (HR, 0.35; 95% CI, 0.13-0.93). Norfloxacin showed no such benefit for patients with ascites fluid protein levels above 15 g/L.

Norfloxacin therapy “could reduce the incidence of death among patients with ascitic fluid protein concentrations of less than 15 g/L but not among those with ascitic fluid protein concentration of 15 g/L or more,” the researchers concluded. “Norfloxacin may prevent some infections, especially gram-negative bacterial infections, but not the development of [spontaneous bacterial peritonitis] and other noninfectious, liver-related complications.”

The study was funded by Programme Hospitalier de Recherche Clinique National 2008 of the French Ministry of Health. Dr. Moreau reported having no conflicts of interest. Two coinvestigators disclosed ties to Gore Norgine, Exalenz, and Conatus.

Body

Prolonged antimicrobial use in patients with decompensated cirrhosis is an area of unclear mortality benefit and may actually increase risk in some patients given antimicrobial resistance. This randomized double-blind, placebo-controlled trial by Moreau et al. evaluates the mortality associated with long-term fluoroquinolone therapy in patients without indications for primary or secondary prophylaxis. Although the study had limited statistical power to detect clear benefit, the authors found that 6-month mortality was not reduced in patients with Child-Pugh class C cirrhosis who received treatment with daily oral fluoroquinolone therapy for 6 months. Subgroup analysis of individuals with ascites fluid total protein levels lower than 15 g/L showed a survival benefit at 6 months.

Determining quantifiable risk for known factors associated with liver disease mortality is a pressing issue, especially in the pretransplant setting where infectious risk is compounded post transplant with changes in gut flora, addition of potent immunosuppressants, and increased metabolic demands. Biologic measurements that correlate with increased complications and mortality, like low protein ascites, are helpful in complex clinical settings.Studying patients with advanced and decompensated liver disease in a systematic, longitudinal manner with any pharmacologic intervention is a particular challenge given the unpredictable nature of decompensation events and variable outcomes from those events. However, attempts to quantify risk and benefit even in this unpredictable patient population is worthwhile to stratify patients for interventions and minimize risk of liver-related and overall mortality – as well as peritransplant complications and posttransplant survival.

Patients with advanced cirrhosis often develop spontaneous bacterial peritonitis and other severe bacterial infections, with potentially grave outcomes. These are often enteric gram-negative bacteria that cross the intestinal barrier, enter the systemic circulation, and travel to the site of infection.

Long-term fluoroquinolone therapy (typically with norfloxacin) might help prevent these bacterial infections, the translocation of bacterial products, systemic inflammation, and consequent end-organ dysfunction, such as acute kidney disease. However, long-term antibiotic therapy also raises the specter of multidrug resistance, which is especially concerning when it involves a crucial antibiotic class such as fluoroquinolones, the researchers noted. “[In] patients receiving prolonged fluoroquinolone therapy, the development of infections by multidrug resistant bacteria might obscure the beneficial effect of fluoroquinolones on survival,” they added.

Four previous blinded and placebo-controlled trials have investigated fluoroquinolone therapy and mortality patients with cirrhosis, but they were small, usually included mortality only as a secondary outcome, and yielded mixed results. Hence, the researchers enrolled 291 patients with advanced (Child-Pugh class C) cirrhosis from 18 clinical sites in France and randomly assigned them to receive either norfloxacin (400 mg once daily) or placebo for 6 months. Patients were evaluated monthly during treatment and then at 9 months and 12 months. The primary outcome was survival at 6 months.

In a post hoc analysis, the researchers examined cumulative death rates at 6 months after accounting for liver transplantation as a competing risk of death and including survival data for patients who developed spontaneous bacterial peritonitis. Taking this approach, the estimated cumulative rate of death at 6 months was 15.5% (95% confidence interval, 10.1-21.9) in the norfloxacin group and 24.8% (95% CI, 18.1-32.1) in the placebo group, for a hazard ratio of 0.59 (95% CI, 0.35-0.99). Among patients whose ascites fluid levels were less than 15 g/L, the hazard ratio for death at 6 months was 65% lower in the norfloxacin group than in the placebo group (HR, 0.35; 95% CI, 0.13-0.93). Norfloxacin showed no such benefit for patients with ascites fluid protein levels above 15 g/L.

Norfloxacin therapy “could reduce the incidence of death among patients with ascitic fluid protein concentrations of less than 15 g/L but not among those with ascitic fluid protein concentration of 15 g/L or more,” the researchers concluded. “Norfloxacin may prevent some infections, especially gram-negative bacterial infections, but not the development of [spontaneous bacterial peritonitis] and other noninfectious, liver-related complications.”

The study was funded by Programme Hospitalier de Recherche Clinique National 2008 of the French Ministry of Health. Dr. Moreau reported having no conflicts of interest. Two coinvestigators disclosed ties to Gore Norgine, Exalenz, and Conatus.

Crohn’s disease tied to anal canal high-risk HPV infection

Article Type
Changed

 

Crohn’s disease was significantly associated with anal canal high-risk human papillomavirus (HPV) infection in a prospective, single-center study of patients undergoing colonoscopy for various indications.

High-risk HPV and HPV strain 16 were detected in 30% of patients with Crohn’s disease and 18% of patients without Crohn’s disease (P = .005), said Lucine Vuitton, MD, of University Hospital of Besançon (France) and her associates. “Increasing our knowledge of HPV infection of anal tissues could help physicians identify populations at risk and promote prophylaxis with vaccination and adequate screening,” the investigators wrote in the November issue of Clinical Gastroenterology and Hepatology.

Most anal cancers are squamous cell carcinomas, for which infection with high-risk HPV (especially high-risk HPV16) is a driving risk factor. Case studies and literature reviews have linked Crohn’s disease to increased rates of anal canal cancers, but population-based data were lacking, the researchers wrote. Therefore, they prospectively analyzed anal tissue samples from 467 consecutive patients undergoing colonoscopy at a tertiary care center in France. Median age was 54 years (interquartile range, 18-86 years), and 52% of patients were women. No patient had detectable macroscopic neoplastic lesions at the anal margin at baseline.

The researchers used the QIAamp DNA Blood minikit (Qiagen) for DNA extraction and the INNO-LiPA HPV Genotyping Extra kit (Fujirebio Diagnostics) for HPV DNA detection and genotyping. These methods identified HPV DNA in anal tissue samples from 34% of the patients and high-risk HPV DNA in 18% of patients. The most prevalent genotype was HPV16 (detected in 7% of samples), followed by HPV51, HPV52, and HPV39.

A total of 112 patients were receiving at least one immunosuppressive treatment for inflammatory bowel disease or another condition. Seventy patients had Crohn’s disease, and 29 patients had ulcerative colitis. The prevalence of anal canal high-risk HPV and HPV16 infection in patients with ulcerative colitis was similar to that seen in those without inflammatory bowel disease. However, patients with Crohn’s disease were more likely to have anal canal high-risk HPV infection (30%) and HPV16 infection (14%), compared with patients without Crohn’s disease (18% and 7%, respectively). Additionally, among 22 patients with Crohn’s disease and perianal involvement, 11 had HPV DNA in the anal canal versus 30% of other patients with inflammatory bowel disease.

Women were more likely to have anal canal high-risk HPV (23%) infection than were men (13%; P = .004). In a multivariable analysis of self-reported data and medical data, significant risk factors for high-risk HPV infection included female sex, a history of sexually transmitted infections, having more than 10 sexual partners over the life course, having at least one sexual partner during the past year, current smoking, and immunosuppressive therapy. The multivariable analysis also linked Crohn’s disease with anal canal high-risk HPV16 infection (odds ratio, 3.8), but the association did not reach statistical significance (95% confidence interval, 0.9-16.9).

Most patients with Crohn’s disease were on immunosuppressive therapy, “which markedly affected statistical power,” the researchers commented. Nonetheless, their findings support HPV vaccination for patients with Crohn’s disease, as well as efforts to target high-risk patients who could benefit from anal cancer screening, they said.

The work was funded by the APICHU research grant from Besançon (France) University Hospital and by the Région de Franche-Comté. Dr. Vuitton disclosed ties to AbbVie, Ferring, MSD, Hospira, Janssen, and Takeda. Three coinvestigators disclosed relationships with AbbVie, MSD, Hospira, Mayoli, and Roche.
