Early TIPS shows superiority to standard care for advanced cirrhosis with acute variceal bleeding
Early TIPS “should therefore be preferred to the current standard of care,” reported lead author Yong Lv, MD, of the Fourth Military Medical University in Xi’an, China, and colleagues, referring to standard pharmaceutical and endoscopic therapy.
“[The current standard] approach has improved patient outcomes,” the investigators wrote in the Lancet Gastroenterology & Hepatology. “However, up to 10%-20% of patients still experience treatment failure, requiring further intensive management. In such patients, [TIPS] is successful in achieving hemostasis in 90%-100% of patients. However, 6-week mortality remains high [35%-55%]. This is probably because the severity of the underlying liver disease has worsened and additional organ dysfunction may have occurred after several failed endoscopic therapy attempts.”
Previous studies have explored earlier intervention with TIPS; however, according to the investigators, these trials were inconclusive for various reasons. For example, uncovered stents and an out-of-date control therapy were employed in a trial by Monescillo et al., while a study by Garcia-Pagan et al. lacked a primary survival endpoint and has been criticized for selection bias. “Thus, whether early TIPS confers a survival benefit in a broader population remains to be assessed,” the investigators wrote.
To this end, the investigators screened 373 patients with advanced cirrhosis (Child-Pugh class B or C) and acute variceal bleeding. Of these, 132 were eligible for inclusion based on age, disease severity, willingness to participate, comorbidities, and other factors. Patients were randomized 2:1 to receive either early TIPS or standard therapy. Within 12 hours of hospital admission for the initial bleeding episode, all patients received vasoactive drugs or endoscopic band ligation and prophylactic antibiotics. Control patients continued vasoactive drugs for up to 5 days, followed by propranolol, which was titrated to reduce resting heart rate by 25% but not less than 55 beats per minute. Elective endoscopic band ligation was performed within 1-2 weeks of initial endoscopic treatment, then approximately every 2 weeks until variceal eradication, and additionally if varices reappeared. TIPS was allowed as rescue therapy. In contrast, patients in the TIPS group underwent the procedure with conscious sedation and local anesthesia within 72 hours of diagnostic endoscopy, followed by approximately 1 week of antibiotics and vasoactive drugs. TIPS revision with angioplasty or another stent placement was performed in the event of shunt dysfunction or reemergence of portal hypertensive complications. The final dataset contained 127 patients, as 3 were excluded after randomization because of exclusionary diagnoses, 1 withdrew consent, and 1 died before TIPS placement.
The primary endpoint was transplantation-free survival. The secondary endpoints were new or worsening ascites based on ultrasound score or sustained ascites necessitating paracentesis, failure to control bleeding or rebleeding, overt hepatic encephalopathy, other complications of portal hypertension, and adverse events.
After a median follow-up of 24 months, data analysis showed a survival benefit associated with early TIPS based on multiple measures. Out of 84 patients in the TIPS group, 15 (18%) died during follow-up, compared with 15 (33%) in the control group. Actuarial transplantation-free survival was also better with TIPS instead of standard therapy at 6 weeks (99% vs. 84%), 1 year (86% vs. 73%), and 2 years (79% vs. 64%). The hazard ratio for transplantation-free survival was 0.50 in favor of TIPS (P = .04). These survival advantages were maintained regardless of hepatitis B virus status or Child-Pugh/Model for End-Stage Liver Disease score.
Similarly to transplantation-free survival, patients treated with TIPS were more likely to be free of uncontrolled bleeding or rebleeding at 1 year (89% vs. 66%) and 2 years (86% vs. 57%). The associated hazard ratio for this outcome favored early TIPS (HR, 0.26; P less than .0001), and univariate and multivariate analysis confirmed an independent protective role. In further support of superiority over standard therapy, patients treated with TIPS were more likely than those in the control group to be free of new or worsening ascites at 1 year (89% vs. 57%) and 2 years (81% vs. 54%).
No significant intergroup differences were found for rates of overt hepatic encephalopathy, hepatic hydrothorax, hepatorenal syndrome, spontaneous bacterial peritonitis, hepatocellular carcinoma, serious adverse events, or nonserious adverse events. At 1 and 3 months, patients in the TIPS group had a slight increase of median bilirubin concentrations and median international normalized ratio; however, these values normalized after 6 months. A similar temporal pattern was observed in early TIPS patients with regard to median Model for End-Stage Liver Disease score.
“[The transplantation-free survival benefit of early TIPS] was probably related to better control of factors contributing to death, such as failure to control bleeding or rebleeding or new or worsening ascites, without increasing the frequency and severity of overt hepatic encephalopathy and other adverse events,” the investigators concluded. “This study provides direct evidence and greater confidence in the recommendations of current guidelines that early TIPS should be performed in high-risk patients without contraindications.
“Future studies addressing whether early TIPS can be equally recommended in Child-Pugh B and C patients are warranted,” the investigators added.
The study was funded by the National Key Technology R&D Program, Boost Program of Xijing Hospital, Optimized Overall Project of Shaanxi Province, and National Natural Science Foundation of China. The investigators reported no conflicts of interest.

Although the paper published by Lv et al. supports early transjugular intrahepatic portosystemic shunt (TIPS) for some patients with cirrhosis and variceal bleeding, Dominique Thabut, MD, and Marika Rudler, MD, pointed out that this conclusion cannot be applied to all patients.
“First ... the landscape of cirrhosis with acute variceal bleeding in China is different from that in Europe,” they wrote. “Second, the authors chose to include patients with Child-Pugh B disease without active bleeding at endoscopy [the largest group of patients in this trial]; such patients are not often seen in Europe. Last, a survival benefit was only observed when the Child-Pugh B and Child-Pugh C patients were combined, with and without active bleeding. Hence, this study does not permit conclusions to be made for patients with Child-Pugh B disease.”
“Overall, the authors should be congratulated for tackling the much debated issue of preemptive TIPS,” Dr. Thabut and Dr. Rudler wrote. “There is now no doubt about the benefit of preemptive TIPS in patients with Child-Pugh C disease. The beneficial effects of preemptive TIPS on ascites should push us to consider this approach in all patients, in the absence of contraindication.”

TEG-guided topped conventional transfusion in cirrhotic patients with variceal bleeding
For patients with cirrhosis, variceal bleeding, and severe coagulopathies, the use of thromboelastography (TEG) to guide transfusion decisions significantly reduced both transfusions and rates of late rebleeding, according to the results of a randomized, open-label trial.
“With the use of TEG, only 13.3% of patients received any blood product, as compared with all patients in the conventional transfusion group,” wrote Gyanranjan Rout, MD, and associates at the All India Institute of Medical Sciences, a tertiary care center in New Delhi. The rate of rebleeding at 6 weeks was more than two-thirds lower with TEG versus the comparator group. The findings were published in the Journal of Clinical Gastroenterology.
Mortality remains high in patients with hepatic cirrhosis and variceal bleeding. Rebleeding is a major concern for these patients, and guidelines disagree on how to correct their coagulopathies so that they can undergo endoscopic treatment of varices. TEG “provides a global assessment of various factors promoting coagulation [platelets and clotting factors] and anticoagulation [fibrinolysis] in a single test,” the researchers noted.
Hence, they randomly assigned 60 adults with hepatic cirrhosis, acute variceal bleeding based on the Baveno VI consensus criteria, and significant coagulopathy (less than 50,000 platelets per mm3 or international normalized ratio under 1.8) to either conventional or TEG-guided transfusion. TEG of fresh blood was performed within 6 hours of hospital admission by using a MonoTEM-A automated thromboelastometer (Framar Hemologix, Rome).
Patients in the TEG group whose blood samples took more than 15 minutes to start forming fibrin received fresh frozen plasma (5 mL/kg of ideal body weight based on the Devine formula). Those whose maximum amplitude (an indicator of clot strength) was less than 30 mm received three units of platelets. Conventionally transfused patients received the same dose of fresh frozen plasma if their international normalized ratio was under 1.8 and the same amount of platelets if their platelet count was under 50,000 per mm3.
The groups had comparable baseline endoscopic findings, international normalized ratios, and hemoglobin and platelet levels. In the TEG group, only four (13.3%) patients underwent blood product transfusions, compared with every patient in the comparator group (P less than .001). Initial endoscopy showed similar control of bleeding between groups. At 5 days, rebleeding was noted in one (3.3%) TEG patient and four (13.3%) conventional transfusion patients (P = .167). At 42 days, this difference reached statistical significance (10% vs. 36.7%; P = .012).
The 6-week mortality rates were 13.3% in the TEG group and 26.7% in the conventional transfusion group (P = .176). The lack of statistical significance “can be explained by the fact that our study was not adequately powered to address the difference in mortality between the two study arms,” the researchers wrote.
The study excluded patients with sepsis, a major reason for coagulopathy in patients with cirrhosis. It also did not assess fibrinogen levels, and no patient received cryoprecipitate. “Our study provides initial data [supporting] the concept that TEG may help to decrease unnecessary blood transfusion and may even decrease 6-week rebleeding rate,” the researchers concluded. “However, this needs to be validated in a larger cohort of patients.”
The investigators did not disclose funding sources. They reported having no conflicts of interest.

Physical activity linked to less cirrhosis-related mortality
SAN DIEGO – People who were more physically active, including those who did strength training, had significantly reduced risks of cirrhosis-related and liver cancer–related mortality, based on 26 years of prospective data from 113,000 participants in the Nurses Health Study and the Health Professionals Follow-Up Study.
Adults in the highest quintile of physical activity in the study had a 73% lower risk for cirrhosis-related death than did those in the lowest quintile, according to researchers at Massachusetts General Hospital and Harvard Medical School, Boston, who presented the study findings at Digestive Disease Week 2019.
One of the researchers, Tracey Simon, MD, MPH, of Massachusetts General Hospital, Boston, broke down the major take-home messages from the study in this video interview.
For example, vigorous activity was not necessary to improve hepatic health, she said. Walking for 4 hours per week made a big difference.
Dr. Simon has no relevant financial disclosures.

SAN DIEGO – People who were more physically active, including those who did strength training, had significantly reduced risks of cirrhosis-related and liver cancer–related mortality, based on 26 years of prospective data from 113,000 participants in the Nurses Health Study and the Health Professionals Follow-Up Study.
Adults in the highest quintile of physical activity in the study had a 73% lower risk for cirrhosis-related death than did those in the lowest quintile, according to researchers at Massachusetts General Hospital and Harvard Medical School, Boston, who presented the study findings at Digestive Disease Week 2019.
One of the researchers, Tracey Simon, MD, MPH, of Massachusetts General Hospital, Boston, broke down the major take-home messages from the study in this video interview.

Study finds link between intrahepatic cholestasis of pregnancy and risk of NAFLD
Patients with intrahepatic cholestasis of pregnancy (ICP) were nearly six times more likely to have a diagnosis of nonalcoholic fatty liver disease (NAFLD) than were controls, results from a retrospective, single-center study demonstrated.
“If this connection is confirmed with future studies, intrahepatic cholestasis of pregnancy may prove a novel model through which to investigate bile acid metabolism in patients with fatty liver disease,” one of the study authors, Tatyana Kushner, MD, MSCE, said during a media briefing in advance of the annual Digestive Disease Week. “This could have implications for future management of fatty liver disease. Additionally, these findings suggest that ICP patients should be seen by a liver specialist because they may go on to develop chronic liver disease or may already have already existing underlying liver disease.”
ICP is characterized by a build-up of bile acids during pregnancy and is associated with an increased risk of negative fetal outcomes and fetal death if left untreated, said Dr. Kushner, of the division of liver diseases at the Icahn School of Medicine at Mount Sinai, New York. The most notable symptom during pregnancy is severe pruritus. In what is believed to be the first study of its kind, Dr. Kushner and colleagues set out to evaluate the association between ICP and NAFLD and associated metabolic risk factors, including obesity, dyslipidemia, hypertension, and diabetes. Between January and December of 2017, they drew from the electronic medical records of a New York City health system to identify 149 pregnancies complicated by ICP and compared them to a control group of 200 pregnancies without an ICP diagnosis. The researchers used Pearson’s chi-square or Fisher’s exact test and Wilcoxon rank-sum tests to evaluate association of ICP with categorical variables and continuous variables, respectively, and unadjusted odds ratios to compare the ICP and control groups for clinically significant outcomes.
The median age of the study population was 30 years, their mean body mass index was 27.5 kg/m2, and there was a higher proportion of Hispanic women in the ICP group, compared with the control group (75% vs. 62%, respectively). Dr. Kushner and colleagues found that Hispanic women were nearly twice as likely to be diagnosed with ICP than non-Hispanic women (OR, 1.90; 95% confidence interval, 1.87-3.03). However, patients in both the ICP and control groups were similar for median age (OR, 1.02; 95% CI, 0.99-1.06), nulliparity (OR, 0.79; 95% CI, 0.48-1.30), and prevalence of hepatitis C (OR, 1.35; 95% CI, 0.08-21.67). The two groups were also similar for certain metabolic risk factors, including prevalence of obesity (OR, 1.01; 95% CI, 0.62-1.61), hypertension (OR, 0.69; 95% CI, 0.31-1.52), hemoglobin A1c greater than 5.5% (OR, 0.80; 95% CI, 0.34-1.9), and total cholesterol above 200 mg/dL (OR, 4.15; 95% CI, 0.83-20.84). Median bile acid levels were 30.6 micromoles (interquartile range, 11.6, 32.7) in the ICP group.
Compared with patients in the control group, those in the ICP group had higher median levels of alanine aminotransferase (ALT) (32 vs. 16 U/L; P less than .0001), alkaline phosphatase (181 vs. 128 U/L; P less than .0001), and total bilirubin (0.5 vs. 0.35 mg/dL; P less than .0001). ICP patients were also more likely than their counterparts to have ALT levels above 50 U/L (two times the upper limit of normal; OR, 3.22; 95% CI, 1.48-7.03), a history of biliary disease (OR, 3.29; 95% CI, 1.39-7.80), and to have evidence of steatosis on liver imaging (OR, 4.69; 95% CI, 1.68-13.12). When the researchers evaluated a diagnosis of NAFLD based on ICD-10 codes or evidence of steatosis on liver imaging, ICP patients were significantly more likely to have a diagnosis of NAFLD than controls (OR, 5.7; 95% CI, 2.08-15.65).
“We recommend additional research to look at differences in NAFLD progression in women who had NAFLD and were later diagnosed with ICP, compared to women with NAFLD who did not go on to develop ICP, because that may be a reflection of the role that bile acid metabolism plays in these particular patients,” Dr. Kushner said.

Type 2 diabetes remission: Reducing excess fat in the liver might be the key
LOS ANGELES – More than 20 years ago, Roy Taylor, MD, began working to further understand the pathogenesis of hepatic insulin resistance in people with type 2 diabetes. It became clear that the main determinant was the amount of fat in the liver.
“If you reduced the amount of fat, the resistance went down,” Dr. Taylor, professor of medicine and metabolism at Newcastle University (England), said at the annual scientific and clinical congress of the American Association of Clinical Endocrinologists. “We had a very clear picture of what might be controlling this awful matter of fasting glucose being too high.”
Then, Dr. Taylor read a study from Caterina Guidone, MD, and colleagues in Italy, which found that 1 week after patients with type 2 diabetes underwent gastric bypass surgery, their fasting plasma glucose levels became normal (Diabetes. 2006;55[7]:2025-31). “I was sitting at my desk and I thought, ‘This really changes type 2 diabetes,’ ” Dr. Taylor said. “It set in process a series of thoughts as to what was controlling what.”
This inspired ongoing work that Dr. Taylor termed the “twin-cycle hypothesis,” which postulates that chronic calorie excess leads to accumulation of liver fat, which spills over into the pancreas (Diabetologia. 2008;51[10]:1781-9).
“People with type 2 diabetes have been in positive calorie balance for a number of years,” he said. “That’s going to lead to an excess of fat in the body, and liver fat levels tend to rise with increasing body weight. If a person has normal insulin sensitivity in muscle tissue, then dealing with a meal is quite easy. Some 30 years ago, we showed using MR spectroscopy that you will have stored the carbohydrate from your breakfast in muscle, to the extent of about one-third of your breakfast, and the peak will be about 5 hours after breakfast. If you had your corn flakes at seven in the morning, by noon there will be peak in muscle, nicely stored away. However, if you happen to be insulin resistant in muscle, that doesn’t happen. There’s only one other pathway that the body can use, and that’s lipogenesis. The body can turn this very toxic substance [glucose] into safe storage [fat]. A lot of that happens in the liver. This means that people with insulin resistance tend to build up liver fat more rapidly than others.”
To test the twin-cycle hypothesis, Dr. Taylor and colleagues launched an 8-week study known as Counterpoint, which set out to induce negative calorie balance using a very low–calorie diet – about one-quarter of an average person’s daily food intake – in 11 people with diabetes (Diabetologia. 2011;54[10]:2506-14). The diet included consuming three packets of liquid formula food each day (46.4% carbohydrate, 32.5% protein, and 20.1% fat; plus vitamins, minerals, and trace elements), supplemented with portions of nonstarchy vegetables such that total energy intake was about 700 calories a day.
“On a liquid-formula diet, hunger is not a problem after the first 36 hours,” Dr. Taylor said. “This is one of the best-kept secrets of the obesity field. Our low-calorie diet was designed as something that people would be able to do in real life. We included nonstarchy vegetables to keep the bowels happy. That was important. It also fulfilled another point. People didn’t want just a liquid diet. They missed the sensation of chewing.”
The researchers also developed three-point Dixon MRI to measure pancreas and liver triacylglycerol content. “The pancreas was particularly challenging, and the full resources of the magnetic resonance physics team were needed to crack the technical problems,” he said.
After just 1 week of restricted energy intake, the fasting plasma glucose level normalized in the diabetic group, going from 9.2 to 5.9 mmol/L (P = .003), while insulin suppression of hepatic glucose output improved from 43% to 74 % (P = .003). By week 8, pancreatic triacylglycerol decreased from 8.0% to 1.1% (P = .03), and hepatic triacylglycerol content fell from 12.8% to 2.9% (P = .003).
“Within 7 days, there was a 30% drop in liver fat, and hepatic insulin resistance had disappeared,” Dr. Taylor said. “This is not a significant change – it’s a disappearance. For one individual, the amount of fat in the liver decreased from 36% to 2%. In fact, 2% [fat in the liver] was the average in the whole group. But what was simply amazing was the change in first-phase insulin response. It gradually increased throughout the 8 weeks of the study to become similar to the normal control group. We knew right away that a low-calorie diet would start correcting this central abnormality of type 2 diabetes.”
After the results from Counterpoint were published, Dr. Taylor received a “tsunami” of emails from researchers and from members of the public. “Some of the medical experts said it was a flash in the pan – interesting, but not relevant,” he said. “People with diabetes learned of it by the media, and it was talked about as a crash diet, which is unfortunate. First, it wasn’t a crash diet. This diet has to be very carefully planned, and people need to think about it in advance. They need to talk about it with their nearest and dearest, because it’s the spouse, the partner, the friends who will be supporting the individual through this journey. That’s critically important. People don’t eat as isolated individuals, they often eat as a family. We’re not talking about cure. We’re talking about reversal of the processes underpinning diabetes, with the aim of achieving remission.”
Dr. Taylor created a website devoted to providing information for clinicians and patients about the low-calorie diet and other tips on how to reverse type 2 diabetes. Soon afterward, he started to receive emails from people telling him about their experiences with the diet. “In the comfort of their own kitchens these people had lost the same amount of weight as in our trial subjects – about 33 pounds,” Dr. Taylor said. “Most of them had gotten rid of their type 2 diabetes. This was not something artificial as part of a research project. This was something that real people would do if the motivation was strong enough.”
To find out if the results from the Counterpoint study were sustainable, Dr. Taylor and his associates launched the Counterbalance study in 30 patients with type 2 diabetes who had a positive calorie imbalance and whom the researchers followed for 6 months. The 8-week diet consisted of consuming three packets of liquid formula a day comprising 43.0% carbohydrates, 34.0% protein, and 19.5% fat, as well as up to 240 g of nonstarchy vegetables (Diabetes Care. 2016;39[5]:808-15). “This was followed for a 6-month period of normal eating: Eating whatever foods they liked but in quantities to keep their weight steady,” Dr. Taylor explained. “These people gained no weight over the 6-month follow-up period. They achieved normalization of liver fat, and it remained normal.”
The patients’ hemoglobin A1c levels fell from an average of 7.1% at baseline to less than 6.0%, and stayed at less than 6.0%. Patients who didn’t respond tended to have a longer duration of diabetes. Their beta cells had fallen to a level beyond that capable of recovery. “So the durability of the return to normal metabolic function was not in question, at least up to 6 months,” he said. “This study also gave us the opportunity to look at changes in pancreas fat. Was it likely that the liver fat was driving the pancreas fat? Yes.”
During the weight-loss period, the researchers found that there was the same degree of reduction of pancreas fat in the Counterbalance study as there’d been in the Counterpoint study. “Remarkably, it decreased slightly during the 6 months of follow-up,” Dr. Taylor said. “Those changes were significant. Type 2 diabetes seems to be caused by about a half a gram of fat within the cells of the pancreas.”
To investigate if a very low–calorie diet could be used as a routine treatment for type 2 diabetes, Dr. Taylor collaborated with his colleague, Mike Lean, MD, in launching the randomized controlled Diabetes Remission Clinical Trial (DiRECT) at 49 primary care practices in the United Kingdom (Diabetologia. 2018;61[3]:589-98). In all, 298 patients were randomized to either best-practice diabetes care alone (control arm) or with an additional evidence-based weight-management program (intervention arm). Remission was defined as having a hemoglobin A1c level of less than 6.5% for at least 2 months without receiving glucose-lowering therapy.
At 1 year, 46% of patients in the intervention arm achieved remission, compared with 4% in the control arm (Lancet Diabetes Endocrinol. 2019;7[5]:344-55). At 2 years, 36% of patients in the intervention arm achieved remission, compared with 2% in the control arm. “The most common comment from study participants was, ‘I feel 10 years younger,’ ” Dr. Taylor said. “That’s important.”
The percentage of patients who achieved remission was 5% in those who lost less than 11 lb (5 kg), 29% in those who lost between 11 lb and 22 lb (5-10 kg), 60% in those who lost between 22 lb and 33 lb (10-15 kg), and 70% in those who lost 33 lb (15 kg) or more.
The researchers found that 62 patients achieved no remission at 12 or 24 months, 15 achieved remission at 12 but not at 24 months, and 48 achieved remission at 12 and 24 months. “We haven’t got this perfectly right yet,” Dr. Taylor said. “There is more work to do in understanding how to achieve prevention of weight gain, maybe with behavioral interventions and/or other agents such as [glucagonlike peptide–1] agonists. This is the start of a story, not the end of it.”
He and his associates also observed that delivery of fat from the liver to the rest of the body was increased in study participants who relapsed. “What effect did that have on the pancreas fat? The people who continued to be free of diabetes showed a slight fall in pancreatic fat between 5 and 24 months,” Dr. Taylor said. “In sharp contrast, the relapsers had a complete increase. Over the whole period of the study, the relapsers had not changed from baseline. It appears beyond reasonable doubt that excess pancreas fat seems to be driving the beta-cell problem underlying type 2 diabetes.”
Dr. Taylor reported that he has received lecture fees from Novartis, Lilly, and Janssen. He has also been an advisory board member for Wilmington Healthcare.

The 8-week diet consisted of consuming three packets of liquid formula a day comprising 43.0% carbohydrates, 34.0% protein, and 19.5% fat, as well as up to 240 g of nonstarchy vegetables (Diabetes Care. 2016;39[5]:808-15). “This was followed for a 6-month period of normal eating: Eating whatever foods they liked but in quantities to keep their weight steady,” Dr. Taylor explained. “These people gained no weight over the 6-month follow-up period. They achieved normalization of liver fat, and it remained normal.”
The patients’ hemoglobin A1c levels fell from an average of 7.1% at baseline to less than 6.0%, and stayed at less than 6.0%. Patients who didn’t respond tended to have a longer duration of diabetes. Their beta cells had fallen to a level beyond that capable of recovery. “So the durability of the return to normal metabolic function was not in question, at least up to 6 months,” he said. “This study also gave us the opportunity to look at changes in pancreas fat. Was it likely that the liver fat was driving the pancreas fat? Yes.”
During the weight-loss period, the researchers found that there was the same degree of reduction of pancreas fat in the Counterbalance study as there’d been in the Counterpoint study. “Remarkably, it decreased slightly during the 6 months of follow-up,” Dr. Taylor said. “Those changes were significant. Type 2 diabetes seems to be caused by about a half a gram of fat within the cells of the pancreas.”
To investigate if a very low–calorie diet could be used as a routine treatment for type 2 diabetes, Dr. Taylor collaborated with his colleague, Mike Lean, MD, in launching the randomized controlled Diabetes Remission Clinical Trial (DiRECT) at 49 primary care practices in the United Kingdom (Diabetologia. 2018;61[3]:589-98). In all, 298 patients were randomized to either best-practice diabetes care alone (control arm) or with an additional evidence-based weight-management program (intervention arm). Remission was defined as having a hemoglobin A1c level of less than 6.5% for at least 2 months without receiving glucose-lowering therapy.
At 1 year, 46% of patients in the intervention arm achieved remission, compared with 4% in the control arm (Lancet Diabetes Endocrinol. 2019;7[5]:344-55). At 2 years, 36% of patients in the intervention arm achieved remission, compared with 2% in the control arm. “The most common comment from study participants was, ‘I feel 10 years younger,’ ” Dr. Taylor said. “That’s important.”
The percentage of patients who achieved remission was 5% in those who lost less than 11 lb (5 kg), 29% in those who lost between 11 lb and 22 lb (5-10 kg), 60% in those who lost between 22 lb and 33 lb (10-15 kg), and 70% in those who lost 33 lb (15 kg) or more.
The researchers found that 62 patients achieved no remission at 12 or 24 months, 15 achieved remission at 12 but not at 24 months, and 48 achieved remission at 12 and 24 months. “We haven’t got this perfectly right yet,” Dr. Taylor said. “There is more work to do in understanding how to achieve prevention of weight gain, maybe with behavioral interventions and/or other agents such as [glucagonlike peptide–1] agonists. This is the start of a story, not the end of it.”
He and his associates also observed that delivery of fat from the liver to the rest of the body was increased in study participants who relapsed. “What effect did that have on the pancreas fat? The people who continued to be free of diabetes showed a slight fall in pancreatic fat between 5 and 24 months,” Dr. Taylor said. “In sharp contrast, the relapsers had a complete increase. Over the whole period of the study, the relapsers had not changed from baseline. It appears beyond reasonable doubt that excess pancreas fat seems to be driving the beta-cell problem underlying type 2 diabetes.”
Dr. Taylor reported that he has received lecture fees from Novartis, Lilly, and Janssen. He has also been an advisory board member for Wilmington Healthcare.
LOS ANGELES – More than 20 years ago, Roy Taylor, MD, began working to further understand the pathogenesis of hepatic insulin resistance in people with type 2 diabetes. It became clear that the main determinant was the amount of fat in the liver.
“If you reduced the amount of fat, the resistance went down,” Dr. Taylor, professor of medicine and metabolism at Newcastle University (England), said at the annual scientific and clinical congress of the American Association of Clinical Endocrinologists. “We had a very clear picture of what might be controlling this awful matter of fasting glucose being too high.”
Then, Dr. Taylor read a study from Caterina Guidone, MD, and colleagues in Italy, which found that 1 week after patients with type 2 diabetes underwent gastric bypass surgery, their fasting plasma glucose levels became normal (Diabetes. 2006;55[7]:2025-31). “I was sitting at my desk and I thought, ‘This really changes type 2 diabetes,’ ” Dr. Taylor said. “It set in process a series of thoughts as to what was controlling what.”
This inspired ongoing work that Dr. Taylor termed the “twin-cycle hypothesis,” which postulates that chronic calorie excess leads to accumulation of liver fat, which spills over into the pancreas (Diabetologia. 2008;51[10]:1781-9).
“People with type 2 diabetes have been in positive calorie balance for a number of years,” he said. “That’s going to lead to an excess of fat in the body, and liver fat levels tend to rise with increasing body weight. If a person has normal insulin sensitivity in muscle tissue, then dealing with a meal is quite easy. Some 30 years ago, we showed using MR spectroscopy that you will have stored the carbohydrate from your breakfast in muscle, to the extent of about one-third of your breakfast, and the peak will be about 5 hours after breakfast. If you had your corn flakes at seven in the morning, by noon there will be peak in muscle, nicely stored away. However, if you happen to be insulin resistant in muscle, that doesn’t happen. There’s only one other pathway that the body can use, and that’s lipogenesis. The body can turn this very toxic substance [glucose] into safe storage [fat]. A lot of that happens in the liver. This means that people with insulin resistance tend to build up liver fat more rapidly than others.”
To test the twin-cycle hypothesis, Dr. Taylor and colleagues launched an 8-week study known as Counterpoint, which set out to induce negative calorie balance using a very low–calorie diet – about one-quarter of an average person’s daily food intake – in 11 people with diabetes (Diabetologia. 2011;54[10]:2506-14). The diet included consuming three packets of liquid formula food each day (46.4% carbohydrate, 32.5% protein, and 20.1% fat; plus vitamins, minerals, and trace elements), supplemented with portions of nonstarchy vegetables such that total energy intake was about 700 calories a day.
“On a liquid-formula diet, hunger is not a problem after the first 36 hours,” Dr. Taylor said. “This is one of the best-kept secrets of the obesity field. Our low-calorie diet was designed as something that people would be able to do in real life. We included nonstarchy vegetables to keep the bowels happy. That was important. It also fulfilled another point. People didn’t want just a liquid diet. They missed the sensation of chewing.”
The researchers also developed three-point Dixon MRI to measure pancreas and liver triacylglycerol content. “The pancreas was particularly challenging, and the full resources of the magnetic resonance physics team were needed to crack the technical problems,” he said.
After just 1 week of restricted energy intake, the fasting plasma glucose level normalized in the diabetic group, going from 9.2 to 5.9 mmol/L (P = .003), while insulin suppression of hepatic glucose output improved from 43% to 74 % (P = .003). By week 8, pancreatic triacylglycerol decreased from 8.0% to 1.1% (P = .03), and hepatic triacylglycerol content fell from 12.8% to 2.9% (P = .003).
“Within 7 days, there was a 30% drop in liver fat, and hepatic insulin resistance had disappeared,” Dr. Taylor said. “This is not a significant change – it’s a disappearance. For one individual, the amount of fat in the liver decreased from 36% to 2%. In fact, 2% [fat in the liver] was the average in the whole group. But what was simply amazing was the change in first-phase insulin response. It gradually increased throughout the 8 weeks of the study to become similar to the normal control group. We knew right away that a low-calorie diet would start correcting this central abnormality of type 2 diabetes.”
After the results from Counterpoint were published, Dr. Taylor received a “tsunami” of emails from researchers and from members of the public. “Some of the medical experts said it was a flash in the pan – interesting, but not relevant,” he said. “People with diabetes learned of it by the media, and it was talked about as a crash diet, which is unfortunate. First, it wasn’t a crash diet. This diet has to be very carefully planned, and people need to think about it in advance. They need to talk about it with their nearest and dearest, because it’s the spouse, the partner, the friends who will be supporting the individual through this journey. That’s critically important. People don’t eat as isolated individuals, they often eat as a family. We’re not talking about cure. We’re talking about reversal of the processes underpinning diabetes, with the aim of achieving remission.”
Dr. Taylor created a website devoted to providing information for clinicians and patients about the low-calorie diet and other tips on how to reverse type 2 diabetes. Soon afterward, he started to receive emails from people telling him about their experiences with the diet. “In the comfort of their own kitchens these people had lost the same amount of weight as in our trial subjects – about 33 pounds,” Dr. Taylor said. “Most of them had gotten rid of their type 2 diabetes. This was not something artificial as part of a research project. This was something that real people would do if the motivation was strong enough.”
To find out if the results from the Counterpoint study were sustainable, Dr. Taylor and his associates launched the Counterbalance study in 30 patients with type 2 diabetes who had a positive calorie imbalance and whom the researchers followed for 6 months.

EXPERT ANALYSIS FROM AACE 2109
Survey: Palliative care blocked by many barriers in end-stage liver disease
results of a recent survey show.
Cultural factors, unrealistic expectations of the patient, lack of reimbursement, and competing demands for physicians’ time were some of the barriers to palliative care cited most frequently in the survey, said the researchers, in their report on the survey results that appears in Clinical Gastroenterology and Hepatology.
Moreover, most responding physicians said they felt end-of-life advance care planning discussions take place too late in the course of illness, according to Nneka N. Ufere, MD, of the Gastrointestinal Unit, Department of Medicine, Massachusetts General Hospital, Boston, and co-authors of the report.
“Multiple interventions targeted at patients, caregivers, institutions, and clinicians are needed to overcome barriers to improve the delivery of high-quality palliative and end-of-life care for patients with end-stage liver disease,” the researchers said.
Specialty palliative care can improve quality of life for patients with life-limiting conditions such as end-stage liver disease, which is associated with poor quality of life and a median survival of just two years without liver transplant, the authors said.
Advance care planning, in which patients discuss goals and care preferences in light of the expected course of illness, was a “critical component” of palliative care that can improve the quality of end-of-life care, Dr. Ufere and co-authors said.
Unfortunately, palliative care planning services are underutilized in end-stage liver disease, studies show, while rates of timely advance care planning discussions are low.
To find out why, Dr. Ufere and colleagues asked 1,238 physicians to fill out a web-based questionnaire designed to assess their perceptions of barriers to use of palliative care and barriers to timely advance care planning discussions. A total of 396 physicians (32%) completed the survey between February and April 2018.
Sixty percent were transplant hepatologists, and 79% of the survey participants said they worked in a teaching hospital, according to Dr. Ufere and co-authors, who added that no respondents had formal palliative care training.
Almost all respondents (95%) agreed that centers providing care for end-stage liver disease patients should have palliative care services, and most (86%) said they thought such patients would benefit from palliative care earlier in the course of disease.
While most (84%) agreed that a hepatologist was the best provider to discuss advance care planning with the patient, only about one-quarter (27%) said the hepatologist was best suited to provide palliative care, while most (88%) said the palliative care specialist was best for that role.
When asked about patient and caregiver barriers, nearly all respondents (95%) agreed that cultural factors that influenced palliative care perception was an issue, while 93% said patients’ unrealistic expectations was an issue.
Clinician barriers that respondents perceived included competing demands for clinicians’ time, cited by 91%, fear that palliative care might destroy the patient’s hope, cited by 82%, and the misperception that palliative care starts when active treatment ends, cited by 81%.
One potential solution to the competing demands on clinicians’ time would be development of “collaborative care models” between palliative care and hepatology services, according to Dr. Ufere and co-authors.
“Outpatient specialty palliative care visits, ideally temporally coordinated with the hepatology visits, can play a role not only in attending to symptom assessment and ACP, but also in addressing important psychosocial aspects of care, such as patient coping and well-being,” they said in their report on the survey.
Institutional barriers of note included limited reimbursement for time spent providing palliative care, cited by 76% and lack of a palliative care service, cited by nearly half (46%).
Some of the most commonly affirmed barriers to timely advance care planning discussions included insufficient training in end-of-life communication issues, and insufficient training in cultural competency issues related to the discussions.
In terms of timeliness, only 17% said advance care planning discussions happen at the right time, while 81% said they happen too late, investigators found.
Funding for the research came from the National Institutes of Health. The authors had no disclosures or conflicts of interest related to the report.

Ribavirin boosts HCV genotype 3 eradication in compensated cirrhotic patients
VIENNA – In patients with compensated cirrhosis infected with genotype 3 hepatitis C virus, adding ribavirin to a usual antiviral regimen of sofosbuvir and velpatasvir significantly boosted the rate of sustained virologic response in a review of more than 14,000 English residents entered in a national registry starting in 2017.
With ribavirin added to a sofosbuvir plus velpatasvir regimen for 12 weeks of treatment, the three-drug combination produced a 98% rate of sustained virologic response after 12 weeks (SVR12) in 196 treated patients, Kate Drysdale, MBBCh, said at the meeting sponsored by the European Association for the Study of the Liver. In contrast, 218 compensated cirrhosis patients who received a 12-week regimen of sofosbuvir plus velpatasvir (Epclusa) but without ribavirin had an SVR12 rate of just under 92%, a statistically significant difference, compared with the rate among patients who also received ribavirin, said Dr. Drysdale, a gastroenterologist at Bart’s Health and Queen Mary University of London. The SVR12 rate among 167 compensated cirrhotic patients treated for 12 weeks with the combination of glecaprevir plus pibrentasvir (Mavyret) was 96%, and not statistically different from the patients who received three drugs including ribavirin. The sofosbuvir, velpatasvir, ribavirin combination also outperformed the combination of sofosbuvir plus daclatasvir (Daklinza) and ribavirin, which produced an SVR12 of 92% in 868 patients. The SVR12 rate is the percentage of patients with undetectable hepatitis C virus (HCV) 12 or more weeks after the end of treatment.
Dr. Drysdale cautioned that the data have not yet been put through a multivariate analysis, but the results so far provide “a strong indication that ribavirin may not be as insignificant” as many have recently presumed. “Ribavirin has been set aside because it was thought not to add to the SVR12, but if patients get only one go at treatment, we must be sure their first treatment is the best one,” Dr. Drysdale said in an interview. If ribavirin can be shown to make a significant contribution to treatment efficacy “then we should think more widely about using it when patients tolerate it.”
The analysis included too few patients with either current decompensated cirrhosis or a history of decompensated cirrhosis to make any statistically meaningful comparisons of the treatment subgroups among these patients. And among patients with genotype 3 HCV infection and without cirrhosis, none of the treatments used in practice showed any statistically significant differences in the SVR12 rates they produced. Among patients without cirrhosis the most commonly used regimens by far were an 8-week course of glecaprevir plus pibrentasvir in 731 patients or a 12-week course of sofosbuvir plus velpatasvir in 1,184 patients. Both regimens had SVR12 rates in noncirrhotic patients of 97%, regardless of whether patients had no, mild, or moderate liver fibrosis.
The study used data collected in an English national registry of HCV-infected patients treated with direct-acting antiviral drugs starting in 2017. Dr. Drysdale and her associates narrowed down the total database of more than 37,000 English adults who received some HCV therapy during the period to 14,603 who received a complete, valid regimen and had follow-up SVR12 information available. The overall SVR12 rate among all these patients was 95.59%, and among the patients infected by genotype 3 virus the SVR12 rate was 95.03%. Dr. Drysdale’s analysis focused primarily on the roughly one-third of patients in the study group infected with genotype 3 HCV, the genotype that historically has presented unique treatment challenges (Drugs. 2017 Feb;77[2]:131-44).
Another finding Dr. Drysdale reported was that as liver disease severity worsened from no fibrosis to mild or moderate fibrosis, and then to compensated cirrhosis or decompensation, the SVR12 rate steadily diminished. Among genotype 3 patients, the SVR12 rate fell from about 97% among patients without any fibrosis to about 87% among those with decompensated cirrhosis. Although this observation had been made before, this finding in such a large number of treated patients adds significant new evidence to support this pattern. It also adds further support to the idea of screening for HCV infection among higher-risk, asymptomatic people to optimize their prospects for virus eradication with treatment.
“If patients get much better treatment outcomes before they become cirrhotic then we should try to find these HCV-infected people before they develop symptoms,” Dr. Drysdale said.
Dr. Drysdale reported no disclosures.

The results from Dr. Drysdale’s analysis confirm what had previously been proposed by other investigators that, in a subgroup of patients with cirrhosis and infected with hepatitis C virus (HCV) genotype 3, adding ribavirin to a regimen of direct-acting antiviral drugs can increase efficacy. But the new study included no data to address the prevalence of HCV genetic variants with resistance mutations that necessitate adding ribavirin. We have known that, in patients with cirrhosis and infected with resistant genotype 3 HCV, adding ribavirin is necessary. In many locations resistance testing is not possible; in those circumstances, adding ribavirin to the treatment should be routinely done.
It’s also been well known that the more advanced a patient’s liver disease, the harder it is to eradicate HCV infection. In general, patients with decompensated liver disease have sustained virologic response rates that are about 10% below the rate in patients without cirrhosis, and Dr. Drysdale reported a similar finding. This fact compels us to diagnose and treat HCV infections earlier. The current focus of the field is on screening for HCV infection among younger adults with risk factors for infection. Unfortunately, many people with an HCV infection are not in regular contact with their local health system, and in many parts of the industrialized world there is only weak practical support for comprehensive screening of at-risk people. Screening programs and recommendations exist, but today these are often ignored and higher-risk young adults frequently do not undergo HCV screening.

The results from Dr. Drysdale’s analysis confirm what had previously been proposed by other investigators that, in a subgroup of patients with cirrhosis and infected with hepatitis C virus (HCV) genotype 3, adding ribavirin to a regimen of direct-acting antiviral drugs can increase efficacy. But the new study included no data to address the prevalence of HCV genetic variants with resistance mutations that necessitate adding ribavirin. We have known that, in patients with cirrhosis and infected with resistant genotype 3 HCV, adding ribavirin is necessary. In many locations resistance testing is not possible; in those circumstances, adding ribavirin to the treatment should be routinely done.
It’s also been well known that the more advanced a patient’s liver disease, the harder it is to eradicate HCV infection. In general, patients with decompensated liver disease have sustained virologic response rates that are about 10% below the rate in patients without cirrhosis, and Dr. Drysdale reported a similar finding. This fact compels us to diagnose and treat HCV infections earlier. The current focus of the field is on screening for HCV infection among younger adults with risk factors for infection. Unfortunately, many people with an HCV infection are not in regular contact with their local health system, and in many parts of the industrialized world there is only weak practical support for comprehensive screening of at-risk people. Screening programs and recommendations exist, but today these are often ignored and higher-risk young adults frequently do not undergo HCV screening.

VIENNA – In patients with compensated cirrhosis infected with genotype 3 hepatitis C virus, adding ribavirin to a usual antiviral regimen of sofosbuvir and velpatasvir significantly boosted the rate of sustained virologic response in a review of more than 14,000 English residents entered in a national registry starting in 2017.
With ribavirin added to a sofosbuvir plus velpatasvir regimen for 12 weeks of treatment, the three-drug combination produced a 98% rate of sustained virologic response after 12 weeks (SVR12) in 196 treated patients, Kate Drysdale, MBBCh, said at the meeting sponsored by the European Association for the Study of the Liver. In contrast, 218 compensated cirrhosis patients who received a 12-week regimen of sofosbuvir plus velpatasvir (Epclusa) but without ribavirin had an SVR12 rate of just under 92%, a statistically significant difference, compared with the rate among patients who also received ribavirin, said Dr. Drysdale, a gastroenterologist at Bart’s Health and Queen Mary University of London. The SVR12 rate among 167 compensated cirrhotic patients treated for 12 weeks with the combination of glecaprevir plus pibrentasvir (Mavyret) was 96%, and not statistically different from the patients who received three drugs including ribavirin. The sofosbuvir, velpatasvir, ribavirin combination also outperformed the combination of sofosbuvir plus daclatasvir (Daklinza) and ribavirin, which produced an SVR12 of 92% in 868 patients. The SVR12 rate is the percentage of patients with undetectable hepatitis C virus (HCV) 12 or more weeks after the end of treatment.
Dr. Drysdale cautioned that the data have not yet been put through a multivariate analysis, but the results so far provide “a strong indication that ribavirin may not be as insignificant” as many have recently presumed. “Ribavirin has been set aside because it was thought not to add to the SVR12, but if patients get only one go at treatment, we must be sure their first treatment is the best one,” Dr. Drysdale said in an interview. If ribavirin can be shown to make a significant contribution to treatment efficacy “then we should think more widely about using it when patients tolerate it.”
The analysis included too few patients with either current decompensated cirrhosis or a history of decompensated cirrhosis to make any statistically meaningful comparisons of the treatment subgroups among these patients. And among patients with genotype 3 HCV infection and without cirrhosis, none of the treatments used in practice showed any statistically significant differences in the SVR12 rates they produced. Among patients without cirrhosis the most commonly used regimens by far were an 8-week course of glecaprevir plus pibrentasvir in 731 patients or a 12-week course of sofosbuvir plus velpatasvir in 1,184 patients. Both regimens had SVR12 rates in noncirrhotic patients of 97%, regardless of whether patients had no, mild, or moderate liver fibrosis.
The study used data collected in an English national registry of HCV-infected patients treated with direct-acting antiviral drugs starting in 2017. Dr. Drysdale and her associates narrowed down the total database of more than 37,000 English adults who received some HCV therapy during the period to 14,603 who received a complete, valid regimen and had follow-up SVR12 information available. The overall SVR12 rate among all these patients was 95.59%, and among the patients infected by genotype 3 virus the SVR12 rate was 95.03%. Dr. Drysdale’s analysis focused primarily on the roughly one-third of patients in the study group infected with genotype 3 HCV, the genotype that historically has presented unique treatment challenges (Drugs. 2017 Feb;77[2]:131-44).
Another finding Dr. Drysdale reported was that as liver disease severity worsened from no fibrosis to mild or moderate fibrosis, and then to compensated cirrhosis or decompensation, the SVR12 rate steadily diminished. Among genotype 3 patients, the SVR12 rate fell from about 97% among patients without any fibrosis to about 87% among those with decompensated cirrhosis. Although this observation had been made before, this finding in such a large number of treated patients adds significant new evidence to support this pattern. It also adds further support to the idea of screening for HCV infection among higher-risk, asymptomatic people to optimize their prospects for virus eradication with treatment.
“If patients get much better treatment outcomes before they become cirrhotic then we should try to find these HCV-infected people before they develop symptoms,” Dr. Drysdale said.
Dr. Drysdale reported no disclosures.

Tailoring the Mediterranean diet for NAFLD
Adults with nonalcoholic fatty liver disease (NAFLD) were more likely to implement the Mediterranean diet when they had greater nutritional knowledge and skills, family support, nutritional care, and positive reinforcement in the media, according to an in-depth study of 19 patients.
Barriers to adopting the diet included “an obesogenic environment, life stressors, and demand for convenience. Poor understanding of the causes and significance of NAFLD adversely affected readiness to change dietary habits,” wrote Laura Haigh of Newcastle University in Newcastle Upon Tyne, England, and associates. The study, which included both standard quantitative methods and semistructured interviews, was published in Clinical Gastroenterology and Hepatology.
The Mediterranean diet emphasizes vegetables, legumes, fish, fruits, whole grains, nuts, and olive oil in lieu of processed foods, sweets, saturated fats, and red meat. This diet has been definitively shown to improve insulin sensitivity and steatosis, even when patients do not lose weight. This has sparked interest in its use for NAFLD disease, but keys to its successful adoption in Northern Europe are not well understood.
Therefore, the researchers recruited 19 NAFLD patients from a tertiary care center in the United Kingdom for a 12-week Mediterranean diet intervention. Most were female, white, in their late 50s, obese, and had type 2 diabetes. “Participants were taught behavioral strategies through the provision of shopping lists, meal planners, and recipes. No advice was given on calorie allowances or physical activities,” the investigators noted.
By using a 14-point assessment tool, they found that dietary adherence rose significantly at 12 weeks, compared with baseline (P = .006). In all, 79% of patients lost weight (mean, 2.4 kg; P = .001 versus baseline), and 72% significantly increased their serum level of HDL cholesterol. Interviews linked successful adoption of the diet with diverse factors, such as believing that NAFLD is lifestyle associated, realizing that healthier nutrition can improve health outcomes, and having access to transportation and budget grocery stories. Patients generally saw the Mediterranean diet as flexible and affordable, but they struggled to adopt it if they worked irregular hours, experienced substantial life stress or were very busy, or tended to eat for self-reward or self-comfort.
Other cited barriers included “diet saboteurs” (including spouses), the plethora of unhealthy foods available in patients’ environments, low nutritional or medical knowledge, and cultural, social, or taste incompatibility, the researchers reported. Taken together, the findings underscore “the futility of a one-size-fits-all approach” when implementing the Mediterranean diet in this population, they concluded. Instead, their patients valued a collaborative, tailored approach – ideally one that incorporated in-person and group-based treatment, as well as online support.
Funders included the North East of England hub of the Allied Health Professions Research Network, the Elucidating Pathways of Steatohepatitis consortium, the Horizon 2020 Framework Program of the European Union, and the Newcastle NIHR Biomedical Research Centre. The researchers reported having no conflicts of interest.

Fecal microbiota transplant shows promise for hepatic encephalopathy
VIENNA –
The oral fecal microbiota transplant (FMT), modeled on guideline-directed treatment for Clostridium difficile (Clin Infect Dis. 2018 April 1;66[7]:e1-48), was linked with a cut in hospitalizations and serious adverse events, as well as a clinically meaningful improvement in a cognitive measure specific for hepatic encephalopathy, Jasmohan S. Bajaj, MD, said at the meeting sponsored by the European Association for the Study of the Liver. Given the preliminary scope of the study, the next step is to assess the treatment in more patients and to evaluate delivery of the FMT specifically to the upper or lower gastrointestinal tract, said Dr. Bajaj, a hepatologist at Virginia Commonwealth University and McGuire VA Medical Center, both in Richmond.
The study included 20 patients with recurrent hepatic encephalopathy (RHE) and a history of at least two encephalopathy episodes despite treatment with lactulose and rifaximin (Xifaxan). After a baseline assessment, 10 patients received a single, oral dose of FMT contained in 15 capsules and composed of fecal material from the OpenBiome collection, and 10 patients received placebo capsules. All of the FMT material came from a single donor and contained a high level of beneficial microbial types, specifically Lachnospiraceae and Ruminococcaceae species. Patients averaged 64 years of age.
During 5 months of follow-up, 6 of the 10 placebo patients had a serious adverse event versus 1 of the 10 patients treated with an active FMT; altogether, there were 11 serious adverse events among the placebo patients versus only 1 event among the FMT patients, Dr. Bajaj reported. Three patients in the control arm had a total of seven hepatic encephalopathy events, compared with a single patient with one event in the intervention arm.
Enrolled patients also underwent two cognitive tests at baseline and during follow-up. Using a Stroop smartphone app (EncephalApp) designed to assess patients with RHE (Hepatology. 2013 Sept;58[3]:1122-32), the researchers found an average 51-second improvement in OffTime+OnTime, a statistically significant and clinically meaningful improvement in the patients treated with FMT, whereas the control patients showed no statistically significant change in this parameter. The second cognitive measure was the average performance by patients using the Psychometric Hepatic Encephalopathy Score (Curr Gastroenterol Rep. 2014 Jan;16[1]:362), which showed no significant change after treatment in either study arm. The actively treated patients also showed favorable changes in the microbial composition of their stool and mucosa, as well as an enhanced small intestinal barrier, following treatment, Dr. Bajaj said.

VIDEO: Givosiran cuts acute intermittent porphyria attacks in pivotal trial
VIENNA – A .
Although the study also identified some safety issues with givosiran, an RNA-inhibitor molecule delivered by subcutaneous injection once a month, the increases in liver enzyme levels it produced in some patients as well as decreased renal function did not seem severe or frequent enough to counterbalance the benefits to treated patients, who often have significant comorbidities and adverse effects because of their disease, Manisha Balwani, MD, said at the meeting sponsored by the European Association for the Study of the Liver. Among the 48 patients assigned to the givosiran group, one patient dropped out because of an adverse effect of treatment.
The results put givosiran on track to become the first Food and Drug Administration–approved treatment for acute hepatic porphyria, a set of similar, rare genetic diseases that produce symptoms in about 1 in every 10,000 people, although asymptomatic disease is likely more common (Hepatol Commun. 2019 Feb;3[2]:193-206). The trial outcomes were also notable for the dramatic improvements in life-disrupting symptoms like pain, nausea, and fatigue that many treated patients experienced.
Patients’ lives were “completely transformed” by givosiran treatment, Dr. Balwani said in a video interview. Patients also had a reduced need for analgesics, including opioids, said Dr. Balwani, a medical geneticist at the Icahn School of Medicine at Mount Sinai in New York.
The ENVISION (A Study to Evaluate the Efficacy and Safety of Givosiran [ALN-AS1] in Patients With Acute Hepatic Porphyrias) study randomized 94 patients who were at least 12 years old and diagnosed with an acute hepatic porphyria, and had experienced at least two porphyria attacks during the prior 6 months. The study ran at 36 sites in 18 countries. Enrolled patients averaged about 39 years old, and had been diagnosed with a hepatic porphyria for an average of about 6 years. During the study, patients did not receive hemin (Panhematin) prophylaxis.
The study’s primary endpoint was the average annualized rate of porphyria attacks during 6 months of treatment, which was 3.2 attacks in 46 patients evaluable for efficacy on givosiran treatment and 12.5 attacks in 43 patients evaluable for efficacy in the control group, a 74% reduction in attacks with givosiran that was statistically significant, Dr. Balwani reported. The percentage of patients with no attacks during the study was 16% among control patients and 50% among those on givosiran. Future analysis of the study data will attempt to identify the patients with the best responses to givosiran.
Among the full cohort of 94 patients enrolled in the study, 21% of the givosiran-treated patients had a adverse reaction, and 17% had a severe adverse reaction, compared with rates of 9% and 11%, respectively, among controls. Three of the serious adverse reactions were judged related to givosiran treatment: one patient with pyrexia, one with abnormal liver function test results, and one patient who developed chronic kidney disease. A total of two patients in the givosiran group developed chronic kidney disease that warranted elective hospitalization for diagnostic evaluation, and an additional three patients on the drug developed chronic kidney disease that did not require hospitalization. Nausea affected 27% of patients on givosiran and 11% of the control patients. Injection-site reactions occurred in 17% of those on givosiran and in none of the placebo patients. An elevation in the serum level of alanine aminotransferase to more than three times the upper limit of normal of baseline occurred in 15% of the givosiran-treated patients and in 2% of the placebo patients.
Givosiran’s small RNA molecule inhibits production of 5‐aminolevulinic acid synthase 1 (ALAS‐1), the rate-limiting enzyme that drives production of the heme precursor molecules that are pathophysiologic in patients with acute hepatic porphyria.

Although the study also identified some safety issues with givosiran, an RNA-inhibitor molecule delivered by subcutaneous injection once a month, the increases in liver enzyme levels it produced in some patients as well as decreased renal function did not seem severe or frequent enough to counterbalance the benefits to treated patients, who often have significant comorbidities and adverse effects because of their disease, Manisha Balwani, MD, said at the meeting sponsored by the European Association for the Study of the Liver. Among the 48 patients assigned to the givosiran group, one patient dropped out because of an adverse effect of treatment.
The results put givosiran on track to become the first Food and Drug Administration–approved treatment for acute hepatic porphyria, a set of similar, rare genetic diseases that produce symptoms in about 1 in every 10,000 people, although asymptomatic disease is likely more common (Hepatol Commun. 2019 Feb;3[2]:193-206). The trial outcomes were also notable for the dramatic improvements in life-disrupting symptoms like pain, nausea, and fatigue that many treated patients experienced.
Patients’ lives were “completely transformed” by givosiran treatment, Dr. Balwani said in a video interview. Patients also had a reduced need for analgesics, including opioids, said Dr. Balwani, a medical geneticist at the Icahn School of Medicine at Mount Sinai in New York.
The ENVISION (A Study to Evaluate the Efficacy and Safety of Givosiran [ALN-AS1] in Patients With Acute Hepatic Porphyrias) study randomized 94 patients who were at least 12 years old and diagnosed with an acute hepatic porphyria, and had experienced at least two porphyria attacks during the prior 6 months. The study ran at 36 sites in 18 countries. Enrolled patients averaged about 39 years old, and had been diagnosed with a hepatic porphyria for an average of about 6 years. During the study, patients did not receive hemin (Panhematin) prophylaxis.
The study’s primary endpoint was the average annualized rate of porphyria attacks during 6 months of treatment, which was 3.2 attacks in 46 patients evaluable for efficacy on givosiran treatment and 12.5 attacks in 43 patients evaluable for efficacy in the control group, a 74% reduction in attacks with givosiran that was statistically significant, Dr. Balwani reported. The percentage of patients with no attacks during the study was 16% among control patients and 50% among those on givosiran. Future analysis of the study data will attempt to identify the patients with the best responses to givosiran.
Among the full cohort of 94 patients enrolled in the study, 21% of the givosiran-treated patients had a adverse reaction, and 17% had a severe adverse reaction, compared with rates of 9% and 11%, respectively, among controls. Three of the serious adverse reactions were judged related to givosiran treatment: one patient with pyrexia, one with abnormal liver function test results, and one patient who developed chronic kidney disease. A total of two patients in the givosiran group developed chronic kidney disease that warranted elective hospitalization for diagnostic evaluation, and an additional three patients on the drug developed chronic kidney disease that did not require hospitalization. Nausea affected 27% of patients on givosiran and 11% of the control patients. Injection-site reactions occurred in 17% of those on givosiran and in none of the placebo patients. An elevation in the serum level of alanine aminotransferase to more than three times the upper limit of normal of baseline occurred in 15% of the givosiran-treated patients and in 2% of the placebo patients.
