Poor NAFLD outcomes with increased VCTE-measured liver stiffness

Tue, 11/22/2022 - 11:27

An increase in liver stiffness measurement (LSM) by vibration-controlled transient elastography (VCTE) may be predictive of poor clinical outcomes in patients with nonalcoholic fatty liver disease (NAFLD), according to new findings presented at the annual meeting of the American Association for the Study of Liver Diseases.
 

Although previous retrospective studies have suggested that increased liver stiffness, as measured by VCTE (FibroScan), is associated with increases in liver-related events, there is a paucity of prospective data, reported Samer Gawrieh, MD, from Indiana University, Carmel and Indianapolis. VCTE is a noninvasive measure of cirrhosis progression.

In their prospective cohort study of patients representing the entire spectrum of NAFLD, the progression to LSM-defined cirrhosis was independently associated with the risk for a composite clinical outcome of death, decompensation, hepatocellular carcinoma, or a Model for End Stage Liver Disease (MELD) score of greater than 15, he said.

Their findings show that “progression to LSM-defined cirrhosis by VCTE is strongly associated with poor clinical outcomes,” Dr. Gawrieh said.
 

Study findings

Investigators looked at prospective data on 894 patients with biopsy-proven NAFLD in the Nonalcoholic Steatohepatitis (NASH) Clinical Research Network database. The sample included patients with a minimum of two LSM readings taken from 2014 through 2022.

They defined LSM-defined cirrhosis as reaching LSM of greater than 14.9 kPa (90% specificity cutoff) among patients without cirrhosis on the baseline VCTE (a 90% sensitivity cutoff of LSM less than 12.1 kPa).

They also performed a histology-based subanalysis, including data only from those patients who had LSM within 6 months of a liver biopsy.

The median patient age was 60 years, 37% were male, and 80.9% were White and 11.5% were Hispanic/Latino. The median body mass index (BMI) was 32.

Out of all the patients, 119 (13.3%) had progression to LSM-defined cirrhosis.

At a median follow-up of 3.69 years for the 775 patients without LSM progression, 79 (10.2%) had one or more of the events in the composite clinical outcome.

In contrast, after a median 5.48 years of follow-up, 31 of the 119 patients with progression (26.1%) had one or more of the composite events (P < .0001).

The median rates of progression to LSM-defined cirrhosis in the overall cohort were 2% at 1 year, 11% at 3 years, and 16% at 5 years.

Researchers found a correlation between progression to LSM-defined cirrhosis and baseline histological fibrosis stage on biopsy, with a rate of 7% among those with no baseline fibrosis, 9% each for patients with stage I A-C or stage II fibrosis, 24% of those with baseline bridging fibrosis, and 25% of those with baseline cirrhosis.

A comparison of the time to a composite clinical outcome event between patients with progression to LSM-defined cirrhosis and those without progression showed that LSM-defined progression was associated with near doubling in risk, with a hazard ratio of 1.84 (P = .0039).

In a multivariate Cox regression analysis controlling for age, sex, race, BMI, diabetes status, and baseline LSM, only LSM-defined progression (HR, 1.93; P < .01) and age (HR, 1.03; P < .01) were significant predictors.

Dr. Gawrieh noted that while age was a statistically significant factor, it was only weakly associated.

“These data suggest that development of cirrhosis LSM criteria is a promising surrogate for clinical outcomes in patients with NAFLD,” Dr. Gawrieh concluded.
 

 

 

Progression definition questioned

Following the presentation, Nezam Afdhal, MD, chief of the division of gastroenterology, hepatology, and nutrition at Beth Israel Deaconess Hospital in Boston, questioned how 25% of patients who had biopsy-proven cirrhosis could progress to LSM-defined cirrhosis.

Dr. Gawrieh said that, according to inclusion criteria, the patients could not have LSM-defined cirrhosis with the sensitivity cutoff of 12.1 kPa, and that of the 10 patients with baseline cirrhosis in the cohort, all had LSM of less than 12.1 kPa. However, he admitted that because those 10 patients were technically not progressors to cirrhosis, they should have been removed from the analysis for clinical outcomes.

Mark Hartman, MD, a clinical researcher at Eli Lilly and Company in Indianapolis, said the study is valuable but noted that those patients who progressed tended to have higher LSM at baseline as well as a higher [fibrosis-4 score].

Dr. Gawrieh added that the investigators are exploring variables that might explain progression to cirrhosis among patients without high baseline liver stiffness, such as alcohol use or drug-induced liver injury.

The study was supported by the National Institutes of Health and the NASH Clinical Research Network institutions. Dr. Gawrieh disclosed research grants from NIH, Zydus, Viking, and Sonic Incytes, and consulting for TransMedics and Pfizer. Dr. Afdhal and Dr. Hartman reported no relevant financial relationships.

Midodrine may be comparable to albumin for PICD prevention in ACLF

Article Type
Changed
Tue, 11/22/2022 - 09:43

For patients with acute-on-chronic liver failure (ACLF) undergoing modest-volume paracentesis for ascites, oral midodrine may be an alternative to intravenous albumin for preventing paracentesis-induced circulatory dysfunction (PICD), according to the results of a randomized controlled trial.

Albumin protected 80% of patients from PICD 6 days after paracentesis, whereas midodrine protected 84%, a difference that was not statistically significant. However, albumin was associated with a slightly higher incidence of adverse events and higher costs, said Mithun Sharma, MD, during his presentation at the annual meeting of the American Association for the Study of Liver Diseases.

Midodrine may be a safer and cost-effective option for these patients, said Dr. Sharma, of the department of hepatology and liver transplantation, AIG Hospitals, Hyderabad, India.

But he cautioned that given the small size of the open-label study, with only 25 patients in each arm, the results should be considered as proof of concept and need to be validated in larger studies.
 

PICD common in ACLF

PICD is caused by fluid shift during paracentesis, leading to a decrease in effective circulating blood volume.

The incidence of PICD after large-volume paracentesis in patients receiving albumin ranges from 12% to 20%, Dr. Sharma noted.

Albumin has been shown in several trials to be effective at reducing the incidence of PICD in patients undergoing paracentesis, but this agent requires IV infusion and is comparatively costly, he said.

In contrast, midodrine, a selective alpha-adrenergic agonist usually prescribed for orthostatic hypotension, may help to prevent PICD through its mechanism of action, maintaining mean arterial pressure (MAP).

In two small studies comparing albumin infusion in patients undergoing paracentesis with 8 liters of fluid removal, midodrine was either inferior to albumin or had no beneficial effect, Dr. Sharma said.

Patients with ACLF, however, have paracentesis with much lower fluid volumes, typically with less than 5 liters removed, and may be good candidates for midodrine.
 

Study details

Dr. Sharma and colleagues tested their hypothesis that in patients with ACLF undergoing modest-volume paracentesis, with fluid removal below 5 liters, midodrine could prevent PICD by increasing MAP, with an efficacy similar to that of intravenous 20% human albumin infusions.

They enrolled 50 patients with ACLF defined by Asian Pacific Association for the Study of the Liver criteria who were undergoing paracentesis with 3- to 4-liter fluid volumes.

They defined PICD as at least a 50% increase in plasma renin activity (PRA) over baseline on the 6th day following paracentesis.

The patients were randomly assigned to receive either intravenous 20% human albumin infusions toward the end of paracentesis or midodrine-hydrochloride 7.5 mg three times daily starting 2 hours before paracentesis. Because of the difference in drug delivery methods, the study could not be blinded to treatment type.

Patients’ mean arterial pressures were recorded daily, renal parameters and serum electrolytes were monitored on days 3 and 6, and blood samples were tested for PRA on day 1 and day 6.

The most common acute and chronic hepatic insults and baseline characteristics of the patients were similar between the groups, with alcohol-related liver disease the most common underlying etiology of cirrhosis.

The incidence of PICD at day 6, the primary endpoint, did not differ significantly between the groups, although mean PRA levels on day 6 were numerically higher in the midodrine group. There was a significant rise in the absolute PRA volume from baseline (P = .006), but this rise did not meet the PICD definition.

Researchers found no significant differences between the two groups in absolute change in PRA, and no significant changes in either group in MAP, creatinine, or sodium levels.
 

 

 

Complications and costs

PICD developed in four patients assigned to the albumin group and five patients assigned to the midodrine group; however, this difference was not significant. Fluid overload occurred in only one patient, in the albumin group.

No cases of hypertension or urinary retention arose in either group.

Grade I/II hepatic encephalopathy occurred 2-3 days after paracentesis in three patients on albumin and in two patients on midodrine.

Acute kidney injury was seen in three patients on albumin and in one patient on midodrine.

At 28 days after paracentesis, three patients in the albumin group had died, all from sepsis and multiorgan failure, while four patients in the midodrine group had died, three from sepsis and multiorgan failure and one from an upper gastrointestinal bleed.

Two patients in the albumin group and one patient in the midodrine group underwent liver transplant 1 month after paracentesis.

A cost-effectiveness analysis showed that the mean cost of albumin infusions was about sixfold higher than that of oral midodrine.
 

More data needed

Session moderator Shiv K. Sarin, MD, from the Institute of Liver and Biliary Sciences in New Delhi, India, who was not involved in the study, commented that while midodrine is a good drug and generally safe, he would wait to use it in patients who needed modest-volume paracentesis until more data are published.

Dr. Sarin also emphasized that albumin is “mandatory” for protecting patients who require large-volume paracentesis, and that it would be “unethical” not to use it in that clinical situation.

The study was internally supported. Dr. Sharma and Dr. Sarin have disclosed no relevant financial relationships.

Bepirovirsen: Is a ‘functional cure’ for HBV on the horizon?

Article Type
Changed
Fri, 11/18/2022 - 10:07

Treatment with bepirovirsen led to sustained clearance of hepatitis B surface antigen (HBsAg) and hepatitis B virus (HBV) DNA for 24 weeks after the end of treatment for adults with chronic HBV in the phase 2b B-Clear study.

The study results were presented at the annual meeting of the American Association for the Study of Liver Diseases and were simultaneously published in The New England Journal of Medicine.

Currently, nucleoside/nucleotide analogue (NA) therapy is the recommended first-line therapy for patients with chronic HBV because it can inhibit viral replication.

However, fewer than 5% of patients have HBsAg loss after 12 months of NA therapy, which underscores the need for therapies that can achieve a “functional” cure, largely defined as sustained, undetectable levels of HBV DNA and HBsAg in the blood, with or without generation of protective antibodies against HBsAg, the researchers noted.

Bepirovirsen is a potential first-in-class antisense oligonucleotide that targets all HBV messenger RNA and acts to decrease levels of viral proteins.

The phase 2b B-Clear study enrolled 457 patients with chronic HBV; 227 were receiving NA therapy, and 230 were not.

Participants were randomly assigned to receive weekly subcutaneous injections of bepirovirsen 300 mg for 24 weeks; bepirovirsen 300 mg for 12 weeks, then 150 mg for 12 weeks; bepirovirsen 300 mg for 12 weeks, then placebo for 12 weeks; or placebo for 12 weeks, then bepirovirsen 300 mg for 12 weeks (groups 1, 2, 3, and 4, respectively).

The composite primary outcome was HBsAg level below the limit of detection and HBV DNA level below the limit of quantification maintained for 24 weeks after the end of bepirovirsen treatment, without newly initiated antiviral medication.

Bepirovirsen 300 mg weekly for 24 weeks (group 1) led to HBsAg and HBV DNA loss in 9% of patients receiving NA therapy and 10% of patients not receiving NA treatment, which was sustained for 24 weeks after the last dose.

For groups 2, 3, and 4, HBsAg and HBV DNA loss occurred in 9%, 3%, and 0%, respectively, of patients receiving NA therapy and 6%, 1%, and 0%, respectively, of patients not receiving NA treatment.

Patients with low baseline HBsAg levels (< 1,000 IU/mL) responded best to treatment with bepirovirsen. Among patients who received bepirovirsen 300 mg weekly for 24 weeks, the primary outcome was achieved by 16% of patients taking NA therapy and by 25% of patients not taking NA therapy.

Although a “relatively low percentage” of patients overall achieved the primary outcome, the study “indicates the possibility of enhanced efficacy with the selection of patients according to baseline characteristics (low HBsAg level at baseline), with combination therapies, or both,” the researchers wrote.

Adverse events with bepirovirsen included injection-site reactions, pyrexia, fatigue, and increased alanine aminotransferase (ALT) levels. Increases in ALT levels, which were more common in those not receiving NA therapy than in those receiving NA therapy (41% vs. 17%), led to two serious adverse events.

On the basis of phase 2b data, GlaxoSmithKline (GSK) plans to advance bepirovirsen into phase 3 development, according to a news release.

Further pursuit of bepirovirsen therapy is “certainly warranted, with the use of a dose of 300 mg per week for at least 24 weeks; indeed, the duration of therapy might be dictated best by HBsAg levels at baseline,” Jay H. Hoofnagle, MD, director of the liver disease research branch at the National Institute of Diabetes and Digestive and Kidney Diseases, wrote in an editorial in the New England Journal of Medicine.

Several critical questions remain, including whether HBsAg negativity will persist beyond 24 weeks, wrote Dr. Hoofnagle, who was not involved in the study.

It’s a question GSK is addressing in the B-Sure trial, which will follow participants for an additional 33 months, the study noted.

Other questions include when NA therapy can be safely stopped, what other factors predict response, and whether RNA therapy–induced loss of HBsAg materially improves long-term outcomes, Dr. Hoofnagle wrote.

“Bepirovirsen is just one RNA-based HBV therapy now being pursued. Several other antisense RNAs as well as the more malleable small interfering RNA molecules (‘-sirans’) are currently in early-phase clinical trials. A new era in the control of hepatitis B may be at hand with these most modern of therapies for this most ancient disease,” Dr. Hoofnagle noted.

The B-Clear study was supported by GSK. Several authors have disclosed relationships with the company. A complete list of author disclosures is available with the original article. Dr. Hoofnagle has disclosed no relevant financial relationships.

Treatment with bepirovirsen led to sustained clearance of hepatitis B surface antigen (HBsAg) and hepatitis B virus (HBV) DNA for 24 weeks after the end of treatment for adults with chronic HBV in the phase 2b B-Clear study.

The study results were presented at the annual meeting of the American Association for the Study of Liver Diseases and were simultaneously published in The New England Journal of Medicine.

Currently, nucleoside/nucleotide analogue (NA) therapy is the recommended first-line therapy for patients with chronic HBV because it can inhibit viral replication.

However, fewer than 5% of patients have HBsAg loss after 12 months of NA therapy, which underscores the need for therapies that can achieve a “functional” cure, largely defined as sustained, undetectable levels of HBV DNA and HBsAg in the blood, with or without generation of protective antibodies against HBsAg, the researchers noted.

Steroids and G-CSF improve 90-day survival in severe alcoholic hepatitis

Article Type
Changed
Tue, 11/15/2022 - 14:13

Adding granulocyte-colony stimulating factor (G-CSF) to steroid therapy can improve 90-day survival for patients with severe alcoholic hepatitis (SAH), researchers from India reported.

Among patients with SAH, the combination of G-CSF and prednisolone was associated with a 90-day survival rate of 88.1%, compared with 78.6% for patients assigned to G-CSF alone, and 64.3% for patients assigned to prednisolone alone (P = .03).

The G-CSF/prednisolone combination was also associated with significantly better steroid responsiveness, as determined by the Lille Model for Alcoholic Hepatitis, reported Shiv K. Sarin, MD, from the Institute of Liver and Biliary Sciences, New Delhi.

The drug combo in steroid-eligible patients also “reduces morbidity related to infections, rehospitalizations, and hepatic encephalopathy [and] reduces infection rates,” Dr. Sarin said at the annual meeting of the American Association for the Study of Liver Diseases. He did caution that the treatment requires close monitoring.
 

Prednisolone-only drawbacks

For patients with SAH, 30-day mortality ranges from 20%-50%. While some patients respond to treatment with corticosteroids, the response is often modest and limited in duration, Dr. Sarin said.

The STOPAH trial found that 15% of patients with SAH treated with prednisolone developed serious infections, compared with 8% of patients on placebo (P = .002), he noted.

Dr. Sarin also pointed to a recent worldwide study attempting to identify the optimal therapeutic window for steroid use in patients with alcoholic hepatitis. The investigators found that corticosteroids reduced 30-day mortality by 41% but only among patients with SAH, especially those with Model for End-Stage Liver Disease (MELD) scores between 25 and 39.

In previous studies, G-CSF has been shown to improve survival in patients with acute-on-chronic liver failure, including patients with SAH; in patients with SAH alone; and in steroid nonresponders, Dr. Sarin said.
 

Regenerative properties

In an interview with this news organizationDr. Sarin said that although the use of G-CSF for patients with severe SAH is still under investigation at his center, “we are using G-CSF routinely for decompensated cirrhosis, where it is like an in vivo extension of regenerative stem cells. G-CSF recruits from bone marrow a lot of hematopoietic stem cells and mesenchymal stem cells.”

Dr. Sarin and colleagues hypothesized that G-CSF, with its immunomodulatory and regenerative properties, would be effective either alone or in combination with steroids in steroid-eligible patients with SAH.

To test this idea, they enrolled 126 patients ages 18-65 with SAH, defined as a Maddrey’s Discriminant Function (mDF) score greater than 32. They excluded patients with active infections, acute gastrointestinal bleeding, hepatorenal syndrome, an mDF score greater than 90, autoimmune hepatitis, hepatitis B or C, HIV, pregnancy, hemophagocytic lymphohistiocytosis, and those with hemoglobin below 8 and baseline white blood cell count over 25,000.

The patients were randomly assigned, 42 in each group, to receive one of the following:

  • Prednisolone monotherapy 40 mg/day for 7 days, with the drug stopped at 7 days for patients with Lille scores above 0.45 or continued for up to 21 days for those with Lille scores below 0.45;
  • Prednisolone plus G-CSF 300 mcg/day for 7 days, with those who achieve a Lille score above 0.45 stopping the steroid but continuing G-CSF, while those with Lille scores below 0.45 continuing on prednisolone for 21 days, plus G-CSF once every 3 days for 5 additional doses; or
  • G-CSF monotherapy at a dose of 150-300 mcg/day for 7 days, then every 3 days for 28 days up to a total of 12 doses.
 

 



Improved response

In addition to its superior results on the primary endpoint of 90-day survival, combination therapy was associated with significantly better response to therapy. The mean Lille score at day 7 was 0.14 for the combination, compared with 0.21 for prednisolone alone and 0.28 for G-CSF alone (= .002).

There were also significantly fewer nonresponders in the combination arm than either of the monotherapy groups (P = .03).

At 90 days, the rate of new infections was significantly higher among patients treated with prednisolone alone, at 35.7%, compared with 19% in the combination arm and 7.1% in the G-CSF alone group (P = .02). There were also significantly fewer skin and mucosal bleeding episodes with the combination (19% vs, 25% and 35.7% with prednisolone and G-CSF monotherapies, respectively, = .03), as well as lower rates of hepatic encephalopathy (9.5% vs. 47.5% and 25%, respectively, P < .01).

No differences in alcohol relapse rates were found among the three groups.
 

Patient selection important

“I know a lot of the G-CSF studies that have been conducted in the U.S. and Europe have all been negative,” said David Goldberg, MD, from the University of Miami, during the session. “Do you think there’s something unique in your patients, the microbiome or maybe genetics, that leads to such different results?” he asked Dr. Sarin.

European studies included patients with infections, acute kidney injury (AKI), or other comorbidities that were exclusion criteria in his study, Dr. Sarin noted.

“If you already have an infection, you already have an AKI, then it’s not a good patient for treatment, so I think the choice of patient is important,” he said.

The study was internally supported. Dr. Sarin and Dr. Goldberg report no relevant financial relationships.

Liver disease-related deaths rise during pandemic

Article Type

Mon, 11/14/2022 - 12:06

 

U.S. mortality for alcohol-associated liver disease (ALD) and non-alcoholic fatty liver disease (NAFLD) increased at “alarming” rates during the COVID-19 pandemic, according to new findings presented at the annual meeting of the American Association for the Study of Liver Diseases.

Dr. Yee Hui Yeo

Between 2019 and 2021, ALD-related deaths increased by 17.6% and NAFLD-related deaths increased by 14.5%, Yee Hui Yeo, MD, a resident physician and hepatology-focused investigator at Cedars-Sinai Medical Center in Los Angeles, said at a preconference press briefing.

“Even before the pandemic, the mortality rates for these two diseases have been increasing, with NAFLD having an even steeper increasing trend,” he said. “During the pandemic, these two diseases had a significant surge.”

Dr. Yeo and colleagues analyzed data from the Center for Disease Control and Prevention’s National Vital Statistic System to estimate the age-standardized mortality rates (ASMR) of liver disease between 2010 and 2021, including ALD, NAFLD, hepatitis B, and hepatitis C. Using prediction modeling analyses based on trends from 2010 to 2019, they predicted mortality rates for 2020-2021 and compared them with the observed rates to quantify the differences related to the pandemic.

Between 2010 and 2021, there were about 626,000 chronic liver disease–related deaths, including about 343,000 ALD-related deaths, 204,000 hepatitis C–related deaths, 58,000 NAFLD-related deaths, and 21,000 hepatitis B–related deaths.

For ALD-related deaths, the annual percentage change was 3.5% for 2010-2019 and 17.6% for 2019-2021. The observed ASMR in 2020 was significantly higher than predicted, at 15.7 deaths per 100,000 people versus 13.0 predicted from the 2010-2019 rate. The trend continued in 2021, with 17.4 deaths per 100,000 people versus 13.4 in the previous decade.

The highest numbers of ALD-related deaths during the COVID-19 pandemic occurred in Alaska, Montana, Wyoming, Colorado, New Mexico, and South Dakota.

For NAFLD-related deaths, the annual percentage change was 7.6% for 2010-2014, 11.8% for 2014-2019, and 14.5% for 2019-2021. The observed ASMR was also higher than predicted, at 3.1 deaths per 100,000 people versus 2.6 in 2020, as well as 3.4 versus 2.8 in 2021.

The highest numbers of NAFLD-related deaths during the COVID-19 pandemic occurred in Oklahoma, Indiana, Kentucky, Tennessee, and West Virginia.
 

Hepatitis B and C gains lost in pandemic

In contrast, the annual percentage change in was –1.9% for hepatitis B and –2.8% for hepatitis C. After new treatment for hepatitis C emerged in 2013-2014, mortality rates were –7.8% for 2014-2019, Dr. Yeo noted.

“However, during the pandemic, we saw that this decrease has become a nonsignificant change,” he said. “That means our progress of the past 5 or 6 years has already stopped during the pandemic.”

By race and ethnicity, the increase in ALD-related mortality was most pronounced in non-Hispanic White, non-Hispanic Black, and Alaska Native/American Indian populations, Dr. Yeo said. Alaska Natives and American Indians had the highest annual percentage change, at 18%, followed by non-Hispanic Whites at 11.7% and non-Hispanic Blacks at 10.8%. There were no significant differences in race and ethnicity for NAFLD-related deaths, although all groups had major increases in recent years.
 

 

 

Biggest rise in young adults

By age, the increase in ALD-related mortality was particularly severe for ages 25-44, with an annual percentage change of 34.6% in 2019-2021, as compared with 13.7% for ages 45-64 and 12.6% for ages 65 and older.

For NAFLD-related deaths, another major increase was observed among ages 25-44, with an annual percentage change of 28.1% for 2019-2021, as compared with 12% for ages 65 and older and 7.4% for ages 45-64.

By sex, the ASMR increase in NAFLD-related mortality was steady throughout 2010-2021 for both men and women. In contrast, ALD-related death increased sharply between 2019 and 2021, with an annual percentage change of 19.1% for women and 16.7% for men.

“The increasing trend in mortality rates for ALD and NAFLD has been quite alarming, with disparities in age, race, and ethnicity,” Dr. Yeo said.

The study received no funding support. Some authors disclosed research funding, advisory board roles, and consulting fees with various pharmaceutical companies.

Living donor liver transplants on rise for most urgent need

Article Type
Changed
Mon, 11/14/2022 - 11:59

Living donor liver transplants (LDLT) for recipients with the most urgent need for a liver transplant in the next 3 months – a model for end-stage liver disease (MELD) score of 25 or higher – have become more frequent during the past decade, according to new findings presented at the annual meeting of the American Association for the Study of Liver Diseases.

Among LDLT recipients, researchers found comparable patient and graft survival at low and high MELD scores. But among patients with high MELD scores, researchers found lower adjusted graft survival and a higher transplant rate among those with living donors, compared with recipients of deceased donor liver transplantation (DDLT).

Dr. Benjamin Rosenthal

The findings suggest certain advantages of LDLT over DDLT may be lost in the high-MELD setting in terms of graft survival, said Benjamin Rosenthal, MD, an internal medicine resident focused on transplant hepatology at the Hospital of the University of Pennsylvania, Philadelphia.

“Historically, in the United States especially, living donor liver transplantation has been offered to patients with low or moderate MELD,” he said. “The outcomes of LDLT at high MELD are currently unknown.”

Previous data from the Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL) found that LDLT offered a survival benefit versus remaining on the wait list, independent of MELD score, he said. A recent study also has demonstrated a survival benefit across MELD scores of 11-26, but findings for MELD scores of 25 and higher have been mixed.

Trends and outcomes in LDLT at high MELD scores

Dr. Rosenthal and colleagues conducted a retrospective cohort study of adult LDLT recipients from 2010 to 2021 using data from the Organ Procurement and Transplantation Network (OPTN), the U.S. donation and transplantation system.

In baseline characteristics among LDLT transplant recipients, there weren’t significant differences in age, sex, race, and ethnicity for MELD scores below 25 or at 25 and higher. There also weren’t significant differences in donor age, relationship, use of nondirected grafts, or percentage of right and left lobe donors for LDLT recipients. However, recipients with high MELD scores had more nonalcoholic steatohepatitis (29.5% versus 24.6%) and alcohol-assisted cirrhosis (21.6% versus 14.3%).

The research team evaluated graft survival among LDLT recipients by MELD below 25 and at 25 or higher. They also compared posttransplant patient and graft survival between LDLT and DDLT recipients with a MELD of 25 or higher. They excluded transplant candidates on the wait list for Status 1/1A, redo transplant, or multiorgan transplant.

Among the 3,590 patients who had LDLT between 2010 and 2021, 342 patients (9.5%) had a MELD of 25 or higher at transplant. There was some progression during the waiting period, Dr. Rosenthal noted, with a median listing MELD score of 19 among those who had a MELD of 25 or higher at transplant and 21 among those who had a MELD of 30 or higher at transplant.

For LDLT recipients with MELD scores above or below 25, researchers found no significant differences in adjusted patient survival or adjusted graft survival.

Then the team compared outcomes of LDLT and DDLT in high-MELD recipients. Among the 67,279-patient DDLT comparator group, 27,552 patients (41%) had a MELD of 25 or higher at transplant.

In terms of LDLT versus DDLT, unadjusted and adjusted patient survival were no different for patients with MELD of 25 or higher. In addition, unadjusted graft survival was no different.

However, adjusted graft survival was worse for LDLT recipients with high MELD scores. In addition, the retransplant rate was higher in LDLT recipients, at 5.7% versus 2.4%.

The reason why graft survival may be worse remains unclear, Dr. Rosenthal said. One hypothesis is that a low graft-to-recipient weight ratio in LDLT can cause small-for-size syndrome. However, these ratios were not available from OPTN.

“Further studies should be done to see what the benefit is, with graft-to-recipient weight ratios included,” he said. “The differences between DDLT and LDLT in this setting should be further explored as well.”

The research team also described temporal and transplant center trends for LDLT by MELD group. For temporal trends, they expanded the study period from 2002-2021.

The found a marked U.S. increase in the percentage of LDLT with a MELD of 25 or higher, particularly in the last decade and especially in the last 5 years. But the percentage of LDLT with high MELD remains lower than 15%, even in recent years, Dr. Rosenthal noted.

Across transplant centers, there was a trend toward centers with increasing LDLT volume having a greater proportion of LDLT recipients with a MELD of 25 or higher. At the 19.6% of centers performing 10 or fewer LDLT during the study period, none of the LDLT recipients had a MELD of 25 or higher, Dr. Rosenthal said.

The authors didn’t report a funding source. The authors declared no relevant disclosures.

Chronic hepatitis B infections associated with a range of liver malignancies

Article Type
Changed
Mon, 11/14/2022 - 12:13

 

Untreated chronic hepatitis B infections are associated with increased risks of most major extrahepatic cancer types, shows a new study conducted in South Korea.

In this study, which was published in the Journal of Clinical Oncology, researchers found that long-term treatment with nucleos(t)ide analogues (NAs) for patients with chronic hepatitis B lowered their risk of developing extrahepatic cancer types.

In addition to lowering the risk of liver cancers, treatment with nucleos(t)ide analogues, including tenofovir disoproxil fumarate, entecavir, lamivudine, telbivudine, adefovir, and clevudine, lowered the risk of developing cancer of the pancreas and prostate, but increased the risk of breast cancer.

By controlling chronic hepatitis B infections (CHB), NAs have been known to reduce the risk of hepatocellular carcinoma and intrahepatic cholangiocarcinoma. About half of the 700,000 people who die each year from chronic hepatitis B infections also have an intrahepatic malignancy.

But extrahepatic cholangiocarcinoma, in which tumors grow outside of the liver in the bile ducts, is exceedingly rare, affecting only 8,000 people each year in the United States.

The study was led by Jeong-Hoon Lee, MD, PhD, Seoul National University, South Korea.
 

The study details

Researchers sought to understand whether CHB treatment with NA drugs could reduce the risk of extrahepatic cancer. The study is based on an analysis of South Korean medical insurance claims data that included 90,944 patients (6,539 treated with NAs) with a newly diagnosed chronic hepatitis B infection, and 685,436 controls. The median age of the groups ranged from 47 to 51, and the percentage of men ranged from 51.3% to 62.5%.

Over the median 47.4-month study period, 3.9% (30,413) of subjects developed cancer outside the liver. Patients with CHB who weren’t treated with NAs had a higher overall risk vs. the NA-treatment group (adjusted subdistribution hazard ratio = 1.28; 95% confidence interval, 1.12-1.45; P < .001) and vs. controls (aSHR = 1.22; 95% CI, 1.18-1.26; P < .001).

The researchers write that “the direction of the original result was maintained” even after adjustment for cancer risk factors such as smoking and alcohol consumption. “Randomized controlled trials might be warranted to explore whether NA treatment will reduce the risk of extrahepatic malignancy in patients with CHB outside the current treatment indication,” they wrote.

In an accompanying commentary, Lewis R. Roberts, MBChB, PhD, of Mayo Clinic, Rochester, Minn., said that what is perhaps “the most controversial result ... one that is not the direct subject of their study, the observation that NA treatment was not associated with a decrease in risk of primary intrahepatic malignancy – hepatocellular carcinoma (HCC) or intrahepatic cholangiocarcinoma. The observed decrease in risk of intrahepatic malignancy was 12%, with an adjusted subdistribution hazard ratio of 0.88 (95% CI, 0.77-1.01; P = .08).”

As Dr. Roberts wrote, the authors suggested this could be related to the low prevalence of cirrhosis in the study group. “This explanation is plausible, as it has previously been shown that the major impact of NA treatment in reducing HCC incidence is in those with CHB-induced cirrhosis,” he wrote.

Dr. Roberts added that randomized trials of NA in CHB would be difficult because the drugs are so effective. “The most important implication of this study may be the observation that CHB is associated with a higher risk of a range of extrahepatic malignancies, and the opportunity to advise patients with CHB to adhere to current recommendations for screening for the major cancer types.”

The study was publicly funded, but several study authors report numerous disclosures including relationships with Yuhan Corporation, Bayer, Gilead Sciences, Bristol Myers Squibb, and others.

Untreated chronic hepatitis B infections are associated with increased risks of most major extrahepatic cancer types, shows a new study conducted in South Korea.

In this study, which was published in the Journal of Clinical Oncology, researchers found that long-term treatment with nucleos(t)ide analogues (NAs) for patients with chronic hepatitis B lowered their risk of developing extrahepatic cancer types.

In addition to lowering the risk of liver cancers, treatment with nucleos(t)ide analogues, including tenofovir disoproxil fumarate, entecavir, lamivudine, telbivudine, adefovir, and clevudine, lowered the risk of developing cancer of the pancreas and prostate, but increased the risk of breast cancer.

By controlling chronic hepatitis B infections (CHB), NAs have been known to reduce the risk of hepatocellular carcinoma and intrahepatic cholangiocarcinoma. About half of the 700,000 people who die each year from chronic hepatitis B infections also have an intrahepatic malignancy.

But extrahepatic cholangiocarcinoma, in which tumors grow outside of the liver in the bile ducts, is exceedingly rare, affecting only 8,000 people each year in the United States.

The study was led by Jeong-Hoon Lee, MD, PhD, Seoul National University, South Korea.

Pediatric celiac disease incidence varies across U.S., Europe

Article Type
Changed
Thu, 11/10/2022 - 07:38

The incidence of new celiac disease with onset by age 10 appears to be rising and varies widely by region, suggesting different environmental, genetic, and epigenetic influences within the United States, according to a new report.

The overall high incidence among pediatric patients warrants a low threshold for screening and additional research on region-specific celiac disease triggers, the authors write.

“Determining the true incidence of celiac disease (CD) is not possible without nonbiased screening for the disease. This is because many cases occur with neither a family history nor with classic symptoms,” write Edwin Liu, MD, a pediatric gastroenterologist at the Children’s Hospital Colorado Anschutz Medical Campus and director of the Colorado Center for Celiac Disease, and colleagues.

“Individuals may have celiac disease autoimmunity without having CD if they have transient or fluctuating antibody levels, low antibody levels without biopsy evaluation, dietary modification influencing further evaluation, or potential celiac disease,” they write.

The study was published online in The American Journal of Gastroenterology.
 

Celiac disease incidence

The Environmental Determinants of Diabetes in the Young (TEDDY) study prospectively follows children born between 2004 and 2010 who are at genetic risk for both type 1 diabetes and CD at six clinical sites in four countries: the United States, Finland, Germany, and Sweden. In the United States, patients are enrolled in Colorado, Georgia, and Washington.

As part of TEDDY, children are longitudinally monitored for celiac disease autoimmunity (CDA) by assessment of autoantibodies to tissue transglutaminase (tTGA). The protocol is designed to analyze the development of persistent tTGA positivity, CDA, and subsequent CD. The study population contains various DQ2.5 and DQ8.1 combinations, which represent the highest-risk human leukocyte antigen (HLA) DQ haplogentotypes for CD.

From September 2004 through February 2010, more than 424,000 newborns were screened for specific HLA haplogenotypes, and 8,676 children were enrolled in TEDDY at the six clinical sites. The eligible haplogenotypes included DQ2.5/DQ2.5, DQ2.5/DQ8.1, DQ8.1/DQ8.1, and DQ8.1/DQ4.2.

Blood samples were obtained and stored every 3 months until age 48 months and at least every 6 months after that. At age 2, participants were screened annually for tTGA. With the first tTGA-positive result, all prior collected samples from the patient were tested for tTGA to determine the earliest time point of autoimmunity.

CDA, a primary study outcome, was defined as positivity in two consecutive tTGA tests at least 3 months apart.

In seropositive children, CD was defined on the basis of a duodenal biopsy with a Marsh score of 2 or higher. The decision to perform a biopsy was determined by the clinical gastroenterologist and was outside of the study protocol. When a biopsy wasn’t performed, participants with an average tTGA of 100 units or greater from two positive tests were considered to have CD for the study purposes.

As of July 2020, among the children who had undergone one or more tTGA tests, 6,628 HLA-typed eligible children were found to carry the DQ2.5, the D8.1, or both haplogenotypes and were included in the analysis. The median follow-up period was 11.5 years.

Overall, 580 children (9%) had a first-degree relative with type 1 diabetes, and 317 children (5%) reported a first-degree relative with CD.

Among the 6,628 children, 1,299 (20%) met the CDA outcome, and 529 (8%) met the study diagnostic criteria for CD on the basis of biopsy or persistently high tTGA levels. The median age at CDA across all sites was 41 months. Most children with CDA were asymptomatic.

Overall, the 10-year cumulative incidence was highest in Sweden, at 8.4% for CDA and 3% for CD. Within the United States, Colorado had the highest cumulative incidence for both endpoints, at 6.5% for CDA and 2.4% for CD. Washington had the lowest incidence across all sites, at 4.6% for CDA and 0.9% for CD.

“CDA and CD risk varied substantially by haplogenotype and by clinical center, but the relative risk by region was preserved regardless of the haplogenotype,” the authors write. “For example, the disease burden for each region remained highest in Sweden and lowest in Washington state for all haplogenotypes.”
 

 

 

Site-specific risks

In the HLA, sex, and family-adjusted model, Colorado children had a 2.5-fold higher risk of CD, compared with Washington children. Likewise, Swedish children had a 1.8-fold higher risk of CD than children in Germany, a 1.7-fold higher than children in the United States, and a 1.4-fold higher risk than children in Finland.

Among DQ2.5 participants, Sweden demonstrated the highest risk, with 63.1% of patients developing CDA by age 10 and 28.3% developing CD by age 10. Finland consistently had a higher incidence of CDA than Colorado, at 60.4% versus 50.9%, for DQ2.5 participants but a lower incidence of CD than Colorado, at 20.3% versus 22.6%.

The research team performed a post hoc sensitivity analysis using a lower tTGA cutoff to reduce bias in site differences for biopsy referral and to increase sensitivity of the CD definition for incidence estimation. When the tTGA cutoff was lowered to an average two-visit tTGA of 67.4 or higher, more children met the serologic criteria for CD.

“Even with this lower cutoff, the differences in the risk of CD between clinical sites and countries were still observed with statistical significance,” the authors write. “This indicates that the regional differences in CD incidence could not be solely attributed to detection biases posed by differential biopsy rates.”

Multiple environmental factors likely account for the differences in autoimmunity among regions, the authors write. These variables include diet, chemical exposures, vaccination patterns, early-life gastrointestinal infections, and interactions among these factors. For instance, the Swedish site has the lowest rotavirus vaccination rates and the highest median gluten intake among the TEDDY sites.

Future prospective studies should capture environmental, genetic, and epigenetic exposures to assess causal pathways and plan for preventive strategies, the authors write. The TEDDY study is pursuing this research.

“From a policy standpoint, this informs future screening practices and supports efforts toward mass screening, at least in some areas,” the authors write. “In the clinical setting, this points to the importance for clinicians to have a low threshold for CD screening in the appropriate clinical setting.”

The TEDDY study is funded by several grants from the National Institute of Diabetes and Digestive and Kidney Diseases, the National Institute of Allergy and Infectious Diseases, the Eunice Kennedy Shriver National Institute of Child Health and Human Development, the National Institute of Environmental Health Sciences, the Centers for Disease Control and Prevention, and the Juvenile Diabetes Research Foundation. The authors have disclosed no relevant financial relationships.

World falls short on HBV, HCV elimination targets

Article Type
Changed
Thu, 11/10/2022 - 10:48

Vaccination campaigns in more than 80 nations have successfully reduced the prevalence of hepatitis B virus (HBV) surface antigen. That’s the good news.
 

Less good is the news that no countries are on track to meet the goals for HBV eradication by 2030 or 2050, and only 11 countries are on track to achieve all absolute or relative targets for hepatitis C virus (HCV) elimination, reported Sarah Blach, MHS, associate director of the Center for Disease Analysis Foundation, based in Lafayette, Colo.

“As countries progress toward eliminating hepatitis B and C, we really need to do more to expand political will and financing of national elimination programs. It’s great to see that it’s happening in some of these countries, but we really need that to expand,” she said at the annual meeting of the American Association for the Study of Liver Diseases.

Ms. Blach presented data from the foundation’s Polaris Observatory, an initiative that provides epidemiological data, modeling tools, training, and decision analytics to support eliminating HBV and HCV globally by 2030.

The investigators used mathematical disease burden models for HBV and HCV to assess worldwide trends toward viral elimination. They also evaluated HBV and HCV elimination policies as reported by authorities in various countries.

They forecast the year in which each country or territory would meet each of the World Health Organization’s four elimination targets from 110 HCV models and 166 HBV models. The targets are 90% diagnosed, 80% of the eligible population treated, 65% reduction in mortality, and 80% incidence reduction for HCV and either 95% incidence reduction or prevalence of 0.1% or less in children aged 5 years and younger for HBV.

Investigators summarized the results across countries by disease area and time period of elimination; that is, elimination before 2030, between 2031 and 2050, or after 2050.
 

Results for HCV and HBV targets

The 11 nations on track to achieve all absolute or relative (programmatic) targets for HCV by 2030 are Australia, Canada, Denmark, Egypt, Finland, France, Georgia, Japan, Norway, Spain, and the United Kingdom.

An additional 24 countries are on track to meet their goals for HCV between 2031 and 2050.

But the rest, including the United States, much of sub-Saharan Africa, China, and South Asia, are not on track to meet their goals for HCV by 2050.

No countries are on track to achieve the absolute or relative (programmatic) targets for elimination of HBV, Ms. Blach said.

However, 83 countries or territories, including the United States, are on track for achieving the HBV surface antigen prevalence target of less than 0.1% in children aged 5 years and younger by 2030.

Ms. Blach and colleagues also looked at results of quantitative policy surveys submitted by 61 countries. The respondents were asked to report on linkage to care, awareness and screening, monitoring and evaluation, ability to expand capacity, harm-reduction programs, financing of national programs, and political will to achieve targets.

The investigators scored countries on a scale of 1-10, with 10 being the highest score, in each category. For HCV, 25 countries (42%) had high scores, defined as 9 or 10, for political will, and 33 countries (54%) had high scores for national funding. For HBV, 17 countries (30%) received the high scores for political will, and 30 (51%) received the high scores for financing the national program.
 

The big picture

Most countries have not expanded HBV or HCV treatment beyond specialists, and HBV policies appear to lag behind policies directed toward HCV elimination, Ms. Blach noted.

“We do need to expand screening and treatment for hepatitis B moving forward,” she said.

The United States and the rest of the world need to do better, especially regarding HBV elimination, but the United States does appear to be making progress, said Richard Sterling, MD, MSc, from Virginia Commonwealth University, Richmond, who comoderated the session where Ms. Blach reported the data.

“My impression is that we’re doing a pretty good job with [HBV] vaccinations in the United States,” Dr. Sterling, who was not involved in the study, said in an interview.

One way to make progress, he said, may be to expand eligibility for HBV vaccines beyond the current upper age limit of 59 years.

Implementing simpler dosing regimens – the currently available vaccine is split into three doses – could improve vaccine compliance and lower costs, Dr. Sterling added.

During the session, Brian Conway, MD, medical director of the Vancouver Infectious Disease Centre, said it seems hard to use a composite set of data to determine a yes/no answer about whether a country is on track to reach targets.

“When you take my country of Canada, we have absolutely no national program, no hope of a national program, very little funding, and yet we make the cut. So how do you balance all these different variables to arrive at a yes/no answer and is there a way of putting a bit more subtlety into it?” Dr. Conway asked Ms. Blach.

Ms. Blach replied that the data are fluid, and countries can move closer or farther from reaching targets over time as conditions change.

Some countries seem to be improving efforts and “just need a bit more” work, Ms. Blach said.

“But we also saw some countries who we thought were going to be a shoo-in, and as time progressed the number of treatments just dropped in shocking ways. The reality is that a lot of countries are struggling to treat patients,” she said.

Canada “has a really great health system. It’s not a fragmented health system, and so even if you don’t have some of that push for elimination from the government level, having access to treatment, having access to those services, means that at least patients can come in and get what they need,” Ms. Blach said.

The study data are available for free on the Center for Disease Analysis Foundation’s Polaris website.

The study was funded by grants from the John C. Martin Foundation, ZeShan Foundation, EndHep2030, Gilead Sciences, and AbbVie. Ms. Blach is employed by the Center for Disease Analysis Foundation, which receives research grants from Gilead and AbbVie. Dr. Sterling and Dr. Conway reported no relevant disclosures.

Vaccination campaigns in more than 80 nations have successfully reduced the prevalence of hepatitis B virus (HBV) surface antigen. That’s the good news.
 

Less good is the news that no countries are on track to meet the goals for HBV eradication by 2030 or 2050, and only 11 countries are on track to achieve all absolute or relative targets for hepatitis C virus (HCV) elimination, reported Sarah Blach, MHS, associate director of the Center for Disease Analysis Foundation, based in Lafayette, Colo.

“As countries progress toward eliminating hepatitis B and C, we really need to do more to expand political will and financing of national elimination programs. It’s great to see that it’s happening in some of these countries, but we really need that to expand,” she said at the annual meeting of the American Association for the Study of Liver Diseases.

NAFLD patients with diabetes have higher fibrosis progression rate

Article Type

Thu, 11/10/2022 - 10:49

 

Among people with nonalcoholic fatty liver disease (NAFLD), the fibrosis progression rate was higher among those who also had diabetes, according to new findings presented at the annual meeting of the American Association for the Study of Liver Diseases.

NAFLD patients with type 2 diabetes progressed by one stage about every 6 years, compared with one stage about every 8 years among patients without diabetes, said Daniel Huang, MBBS, a visiting scholar at the University of California San Diego (UCSD) NAFLD Research Center and a transplant hepatologist at National University Hospital in Singapore.

Dr. Daniel Huang

“We now know that fibrosis stage is a major determinant of liver-related outcomes in NAFLD, as well as overall mortality,” he said. “Liver fibrosis progresses by approximately one stage every 7 years for individuals with NASH (nonalcoholic steatohepatitis).”

Recent UCSD data have indicated that about 14% of patients over age 50 with type 2 diabetes have NAFLD with advanced fibrosis, he noted. Previous studies have shown that diabetes is associated with higher rates of advanced fibrosis, cirrhosis, and hepatocellular carcinoma, but limited data exist around whether the fibrosis progression rate is higher among diabetics.
 

National study cohort

Dr. Huang and colleagues conducted a multicenter, multiethnic prospective cohort study within the NASH Clinical Research Network consortium to examine the fibrosis progression rate and the fibrosis regression rate among patients with or without diabetes. The study included adult participants at eight sites across the United States who had biopsy-confirmed NAFLD and available paired liver biopsies that were at least 1 year apart.

Clinical and laboratory data were obtained at enrollment and prospectively at 48-week intervals and recorded at the time of any liver biopsies. A central pathology committee conducted the liver histology assessment, and the entire pathology committee was blinded to clinical data and the sequence of liver biopsy. The fibrosis progression and regression rates were defined as the change in fibrosis stage over time between biopsies, measured in years.

The study comprised 447 adult participants with NAFLD: 208 patients with type 2 diabetes and 239 patients without diabetes, Dr. Huang said. The mean age was 51, and the mean body mass index was 34.7. The patients with diabetes were more likely to be older, to be women, and to have metabolic syndrome, NASH, and a higher fibrosis stage.

Notably, the median HbA1c among patients with diabetes was 6.8%, indicating a cohort with fairly well-controlled blood sugar. The median time between biopsies was 3.3 years.
 

Difference in progression, not regression

Overall, 151 participants (34%) experienced fibrosis progression, the primary study outcome. In a secondary outcome, 102 participants (23%) had fibrosis regression. The remaining 194 participants (43%) had no change in fibrosis stage. About 26% of patients with types 2 diabetes progressed to advanced fibrosis, as compared with 14.1% of patients without diabetes.

Among all those with fibrosis progression, the rate was 0.15 stages per year, with an average progression rate of one stage over 6.7 years. For patients with diabetes, the progression rate was significantly higher at 0.17 stages per year, compared with 0.13 stages per year among patients without diabetes, Dr. Huang said. That translated to an average progression of one stage over 5.9 years for patients with diabetes and 7.7 years for patients without diabetes.

In contrast, the regression rate was similar between those with or without diabetes at baseline, at –0.13 stages per year for those with diabetes versus –0.14 stages per year for those without diabetes. The similar outcome translated to an average regression of one stage over 7.7 years among those with diabetes and 7.1 years among those without diabetes.

Type 2 diabetes was an independent predictor of fibrosis progression in NAFLD, in both unadjusted and multivariable adjusted models, including baseline fibrosis stage, Dr. Huang said. In addition, patients with diabetes had a significantly higher cumulative incidence of fibrosis progression at 4 years (23% versus 19%), 8 years (59% versus 49%), and 12 years (93% versus 76%).

The research team didn’t find a significant difference in HbA1c as a predictor of fibrosis progression when using a cutoff of 7%.

“It is possible that poor glycemic control may accelerate fibrosis further, but we need studies to validate this,” Dr. Huang said. “These data have important implications for clinical practice and clinical trial design. Patients with NAFLD and diabetes may require more frequent monitoring for disease progression.”

The NASH Clinical Research Network consortium is sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases. Dr. Huang has served on an advisory board for Eisai. The other authors declared various research support and advisory roles with numerous pharmaceutical companies.
