Hypoxia of obstructive sleep apnea aggravates NAFLD, NASH in adolescents
A new study has found that a strong association exists in adolescents who have obstructive sleep apnea, and their risks of developing more highly progressed forms of nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH).
“Substantial evidence suggests oxidative stress is a central mediator in NAFLD pathogenesis and progression, although the specific trigger for reactive oxygen species (ROS) generation has not been clearly delineated,” wrote the authors, led by Shikha S. Sundaram, MD of the University of Colorado at Denver, Aurora, adding that “Emerging evidence demonstrates that obesity-related obstructive sleep apnea (OSA) and intermittent nocturnal hypoxia are associated with NAFLD progression.”
Dr. Sundaram and her coinvestigators looked at patients admitted to the Children’s Hospital Colorado Pediatric Liver Center from June 2009 through January 2014. Subjects included were children ages 8-18 years, male and female, who were classified as Tanner stage 2-4 with liver biopsy evidence of NAFLD.
“In our center, a clinical liver biopsy for suspected NAFLD is performed in overweight or obese children (body mass index greater than 85% for age and gender) with chronically elevated aminotransferases in whom a diagnosis is unclear based on serologic testing,” Dr. Sundaram and her coauthors clarified regarding the screening process.
Additionally, age-matched “lean” children, that is, those with a body mass index lower than 85%, were also enrolled as controls; these subjects were included if they had no evidence of hepatomegaly or liver disease – translated to AST and ALT levels of 640 IU/L – and were also Tanner stage 2-4. The authors explained that this Tanner stage range was chosen in order to “minimize variations in insulin sensitivity that may confound the interpretation of potential associations between OSA/hypoxia and NAFLD.”
Ultimately, 36 NAFLD adolescent subjects and 14 controls completed the study. A total of 25 of the 36 NAFLD subjects (69.4%) had OSA and/or nocturnal hypoxia; of these, 15 were classified as having isolated OSA, 9 had both OSA and hypoxia, and 1 had isolated hypoxia. Polysomnograms found that all NAFLD subjects spent more than 12% of their total time asleep in REM sleep, which was deemed adequate enough to consider the findings valid.
Based on liver histology scoring, laboratory testing, urine F2-isoprostanes, and 4-hydroxynonenal liver immunohistochemistry tests that were conducted on all subjects, Dr. Sundaram and her coinvestigators found that subjects with OSA or hypoxia had more severe fibrosis than did those without. While the latter cohort were 100% stage 0-2, only 64% of those with OSA/hypoxia were stage 0-2, while the remaining 36% were stage 3 (P = .03). Additionally, higher F2-isoprostanes – used to measure lipid peroxidation – correlated with apnea/hypoxia index (r = 0.39; P = .03), and the most severe OSA/hypoxia occurred in subjects that had the greatest 4-hydroxynonenal staining (P = .03). Furthermore, an increase in both F2-isoprostanes and 4-hydroxynonenal hepatic staining was shown to lead to a higher risk of worse steatosis: r = 0.32 and r = 0.47, respectively (P = .04 and P = .007).
“These data support sleep disordered breathing as an important trigger of oxidative stress that promotes progression of pediatric NAFLD to NASH,” the authors concluded, adding that “this study confirms that OSA/hypoxia is common in pediatric NAFLD and that more severe OSA/hypoxia is associated with elevated aminotransferases, hepatic steatosis, inflammation, NAS [NAFLD activity score], and fibrosis.”
Dr. Sundaram and her coauthors call for further research to examine if “prevention or reversal of NASH following effective therapy of OSA and nocturnal hypoxia in obese patients” is viable.
This study was supported by funding from the National Institutes of Health. Dr. Sundaram and her coinvestigators did not report any relevant financial disclosures.

Study finds clues to fibrosis progression in chronic HCV infection
Fibrosis progression in hepatitis C virus–infected individuals is not linear, is associated with Clues to fibrosis progression in chronic hepatitis C infectionClues to fibrosis progression in chronic hepatitis C infection–related flares, and varies according to stage, with those who are least fibrotic tending to have the highest progression, according to a study.
Identifying which patients with hepatitis C virus (HCV) infection will likely progress to cirrhosis has historically been a challenge, creating some difficulty adhering to guidelines recommending that patients at greater risk of fibrosis be among those prioritized for treatment. Having an ability to more accurately diagnose those most at risk could help to better guide treatment prioritization and clinical management.
To that end, Marija Zeremski, PhD, and her colleagues at Weill Cornell Medical School, New York, analyzed 936 biopsies taken from 378 patients seen at a single site between 1997 and 2013. At the time of the first biopsy, nearly two-thirds of the patients were white men in their late 40s to mid-50s, with chronic HCV infection. Nearly 88% of all patients were HCV genotype 1 infected (J Infect Dis. 2016. doi: 10.1093/infdis/jiw332).
In the study, investigators found that between the first and a follow-up biopsy, 57.4% of patients progressed by at least one fibrosis stage, 16.1% of patients had more severe fibrosis progressions of at least two stages, and 10.6% developed either stage 3-4 or 4, with nearly 6% of patients progressing to cirrhosis. Fibrosis progression between the first and last biopsies was associated with less fibrosis on the first biopsy (P less than .001).
Increased necroinflammation and the presence of at least one alanine aminotransferase (ALT) flare greater than 200 U/L during follow-up was also significantly associated with fibrosis progression (odds ratio [OR], 2.64, P less than .007). HCV genotype 3–infected patients were significantly more likely to progress to cirrhosis (P less than .001).
Intrahepatic inflammation at the time of the initial biopsy was at grade 1 or lower in 36.4% of patients, while 56.9% of patients had grade 2 (moderate) inflammation. Severe inflammation (grade 3 or higher) was found in 6.7% of patients reviewed. There was no fibrosis in 11.9% of patients, stage 1 level of fibrosis in 32.3%, stage 2 in 39.4%, and stage 3 in 16.4% of patients.
Moderate to severe fibrosis, defined as equal to or greater than stage 2, was significantly associated with elevated inflammation (greater or equal to grade 2) on the initial biopsy (OR, 9.00; P less than .001). Steatosis testing was performed on 222 patients; 59% tested positive for it. This was significantly associated with stage 2 or higher fibrosis (OR, 2.39; P = .002), and grade 2 or higher levels of inflammation (OR, 4.07; P less than .001) on the initial biopsy.
The highest fibrosis progression rate occurred between stages 0 and 1; the lowest, between stages 2 and 3.
Consecutive biopsies were separated by at least 1 year; patients were either HCV treatment naive or were treatment nonresponders. There were a total of 558 consecutive biopsy pairs available to analyze stage progression. The time between the first and last biopsies was 6.5 years (plus or minus 3 years), while the mean duration between adjacent biopsies was 4.4 years (plus or minus 1.9 years). Data regarding HCV treatment between liver biopsies were available for all but 45 patients. Forty-three percent of the remaining patients did not achieve a sustained virologic response after treatment.
Patients who’d had a cirrhosis diagnosis according to the first biopsy, those for whom treatment induced viral eradication, or those who’d had liver transplantation between biopsies were all excluded from the review.
The investigators wrote that their finding about the association between genotype 3 and cirrhosis should be “interpreted cautiously” because of the low number of these patients in their study.

Hepatitis outlook: July 2016
If you work on the front lines of medical care treating patients with hepatitis, you may not have time to review all the hepatitis research that enters the medical literature every month. Here’s a quick look at some notable news items and journal articles published over the past month, covering a variety of the major hepatitis viruses.
Although hepatitis E virus infections are increasingly recognized as a global public health problem, there are “few methods for prevention and treatment that are widely available,” according to a recent analysis.
A “suboptimal plasma level of the antiviral drug daclatasvir allows the selection of resistance-associated variants” and fails to contribute to antiviral activity in HIV-hepatitis C virus (HCV) coinfected patients, according to a recent study, although no definite reason for the low daclatasvir level was found.
The new preservative-free inactivated hepatitis A vaccine (Healive) in two doses showed better persistence of antibody concentrations for 5 years after full-course immunization among children, compared with Havrix. The endurance of protective immunogenicity was estimated for at least 20 years.
Because of transplacental transfer of antihepatitis B virus antibodies (anti-HBVs), high levels of maternal anti-HBVs may suppress infants’ immune response to standard HBV vaccination, according to an analysis in the Journal of Viral Hepatitis.
The gamma-glutamyl transpeptidase-to-platelet ratio (GPR) is “a new serum model for the diagnosis” of liver fibrosis and cirrhosis, according to a recent study. Researchers said it shows advantages in Chinese hepatitis Be antigen (HBeAg)-positive patients with hepatitis B virus DNA greater than or equal to 5 log10 copies/mL and ALT less than or equal to two times ULN (upper limit of normal), compared with APRI (aspartate aminotransferase to platelet ratio index) and Fibrosis-4.
A baseline quantitative hepatitis B surface antigen (HBsAg) threshold of 3.141 log10 IU/mL and a baseline quantitative hepatitis B core-related antigen 3.450 log10 U/mL threshold, used separately or in combination, allow prediction of response to pegylated interferon-alpha-2a (PegIFN)-based “precision therapy” for hepatitis B virus infection, a new study found.
Male sex, age over 40 years, cirrhotic liver, and long length of stay are significant factors associated with death in hepatitis A virus-hospitalized cases, according to a study in the Journal of Viral Hepatitis.
Chronic kidney disease patients receiving three doses of hepatitis B adjuvanted vaccine were three times more likely to seroconvert than patients immunized with nonadjuvanted vaccines, according to results of a Spanish study. This meant fewer patients needed a second course of HBV vaccination and there were fewer outpatient visits.
Acute kidney injury is closely linked with increased short-term mortality in Chinese hepatitis B virus-related, acute-on-chronic liver failure patients, according to a study in the Journal of Viral Hepatitis.
Italian investigators attempted “to predict susceptibility of healthy patients to de novo HBV infection using a cultured IFN-gamma enzyme-linked immunospot (ELISPOT) assay.” Although the prognostic value of the assay was not demonstrated, data suggested that the subjects may be at risk for HBV infection.
Investigators demonstrated that treatment with sofosbuvir and simeprevir was effective in a real-life cohort of patients with hepatitis C virus genotype 4 infection and advanced liver fibrosis/cirrhosis. They said that adding ribavirin could be considered in treatment-experienced patients.
The presence of specific anti-envelope antibodies may be a factor that helps individuals at high risk of hepatitis C virus to resist infection, according to a study in the Journal of Viral Hepatitis.
A Chinese study determined that certain social network structural characteristics are related to hepatitis C virus infections in people who inject drugs, and used the data to identify the most susceptible individuals for HCV transmission in a network of people who inject drugs.
Drug resistance analyses of protease inhibitors that treat hepatitis C virus infection can be useful and essential in revealing the particular variants responsible for pretreatment natural resistance and also the particular mutations responsible for the viral breakthrough that may develop during the treatment, according to a study in the International Journal of Infectious Diseases.
Routine vaccination of toddlers against hepatitis A virus would be cost effective in Mexico using a single-dose vaccination strategy, according to a recent study, although the authors said the cost efficacy of a second dose depends on the assumptions of added safeguards by immune memory protection and the time horizon over which the analysis is enacted.
Hepatitis C virus-infected patients undergoing ribavirin-free sofosbuvir and velpatasvir regimens had significantly better patient-reported outcome scores during therapy, compared with those undergoing the ribavirin-containing regimen, a recent study found.
An analysis in Infectious Diseases in Clinical Practice reported the first case of visual hallucinations during chronic hepatitis C treatment with sofosbuvir and simeprevir. Investigators said hallucinations stopped upon starting antipsychotic medication, and the remainder of treatment was safe.
Sustained virologic response can be attained with pegylated interferon-alpha plus ribavirin combination therapy in hepatitis C virus–infected patients, but a relapse may occur in some patients, according to a recent study.
A quantitative HBsAg test can be used to ascertain high levels of hepatitis B viremia in women who might transmit the virus to their children, rather than a test for HBeAg or HBV DNA, according to a research letter in Hepatology.
The prevalence of antihepatitis E virus (HEV) antibodies was 49% (153/313) among blood donors in central Italy, according to a study published in Eurosurveillance. The authors said HEV infection is hyperendemic among blood donors (80% men, 18- to 64-years-old) from central Italy and associated with local dietary habits, such as eating raw dried pig liver sausage.

Investigators demonstrated that treatment with sofosbuvir and simeprevir was effective in a real-life cohort of patients with hepatitis C virus genotype 4 infection and advanced liver fibrosis/cirrhosis. They said that adding ribavirin could be considered in treatment-experienced patients.
The presence of specific anti-envelope antibodies may be a factor that helps individuals at high risk of hepatitis C virus to resist infection, according to a study in the Journal of Viral Hepatitis.
A Chinese study determined that certain social network structural characteristics are related to hepatitis C virus infections in people who inject drugs, and used the data to identify the most susceptible individuals for HCV transmission in a network of people who inject drugs.
Drug resistance analyses of protease inhibitors that treat hepatitis C virus infection can be useful and essential in revealing the particular variants responsible for pretreatment natural resistance and also the particular mutations responsible for the viral breakthrough that may develop during the treatment, according to a study in the International Journal of Infectious Diseases.
Routine vaccination of toddlers against hepatitis A virus would be cost effective in Mexico using a single-dose vaccination strategy, according to a recent study, although the authors said the cost efficacy of a second dose depends on the assumptions of added safeguards by immune memory protection and the time horizon over which the analysis is enacted.
Hepatitis C virus-infected patients undergoing ribavirin-free sofosbuvir and velpatasvir regimens had significantly better patient-reported outcome scores during therapy, compared with those undergoing the ribavirin-containing regimen, a recent study found.
An analysis in Infectious Diseases in Clinical Practice reported the first case of visual hallucinations during chronic hepatitis C treatment with sofosbuvir and simeprevir. Investigators said hallucinations stopped upon starting antipsychotic medication, and the remainder of treatment was safe.
Sustained virologic response can be attained with pegylated interferon-alpha plus ribavirin combination therapy in hepatitis C virus–infected patients, but a relapse may occur in some patients, according to a recent study.
A quantitative HBsAg test can be used to ascertain high levels of hepatitis B viremia in women who might transmit the virus to their children, rather than a test for HBeAg or HBV DNA, according to a research letter in Hepatology.
The prevalence of antihepatitis E virus (HEV) antibodies was 49% (153/313) among blood donors in central Italy, according to a study published in Eurosurveillance. The authors said HEV infection is hyperendemic among blood donors (80% men, 18- to 64-years-old) from central Italy and associated with local dietary habits, such as eating raw dried pig liver sausage.

If you work on the front lines of medical care treating patients with hepatitis, you may not have time to review all the hepatitis research that enters the medical literature every month. Here’s a quick look at some notable news items and journal articles published over the past month, covering a variety of the major hepatitis viruses.
Although hepatitis E virus infections are increasingly recognized as a global public health problem, there are “few methods for prevention and treatment that are widely available,” according to a recent analysis.
A “suboptimal plasma level of the antiviral drug daclatasvir allows the selection of resistance-associated variants” and fails to contribute to antiviral activity in HIV-hepatitis C virus (HCV) coinfected patients, according to a recent study, although no definite reason for the low daclatasvir level was found.
The new preservative-free inactivated hepatitis A vaccine (Healive) in two doses showed better persistence of antibody concentrations for 5 years after full-course immunization among children, compared with Havrix. The endurance of protective immunogenicity was estimated for at least 20 years.
Because of transplacental transfer of antihepatitis B virus antibodies (anti-HBVs), high levels of maternal anti-HBVs may suppress infants’ immune response to standard HBV vaccination, according to an analysis in the Journal of Viral Hepatitis.
The gamma-glutamyl transpeptidase-to-platelet ratio (GPR) is “a new serum model for the diagnosis” of liver fibrosis and cirrhosis, according to a recent study. Researchers said it shows advantages in Chinese hepatitis Be antigen (HBeAg)-positive patients with hepatitis B virus DNA greater than or equal to 5 log10 copies/mL and ALT less than or equal to two times ULN (upper limit of normal), compared with APRI (aspartate aminotransferase to platelet ratio index) and Fibrosis-4.
A baseline quantitative hepatitis B surface antigen (HBsAg) threshold of 3.141 log10 IU/mL and a baseline quantitative hepatitis B core-related antigen 3.450 log10 U/mL threshold, used separately or in combination, allow prediction of response to pegylated interferon-alpha-2a (PegIFN)-based “precision therapy” for hepatitis B virus infection, a new study found.
Male sex, age over 40 years, cirrhotic liver, and long length of stay are significant factors associated with death in hepatitis A virus-hospitalized cases, according to a study in the Journal of Viral Hepatitis.
Chronic kidney disease patients receiving three doses of hepatitis B adjuvanted vaccine were three times more likely to seroconvert than patients immunized with nonadjuvanted vaccines, according to results of a Spanish study. This meant fewer patients needed a second course of HBV vaccination and there were fewer outpatient visits.

Links found between NAFLD, type 2 diabetes, and NASH in children
Nearly one in three children with nonalcoholic fatty liver disease have abnormal glucose metabolism, and this co-morbidity is also associated with a greater risk of nonalcoholic steatohepatitis, according to a cross-sectional study published online Aug. 1 in JAMA Pediatrics.
The study used data from 675 children with biopsy-confirmed nonalcoholic fatty liver disease (NAFLD) who were enrolled in the NASH Clinical Research Network. The mean age of the children was 12.6 years, and they had a mean BMI of 32.5. Most of the children in the study were boys and Hispanic.
Overall, 23.4% of study participants had prediabetes and 6.5% met the clinical criteria for type 2 diabetes. However, girls with NAFLD had a 60% greater risk of prediabetes and a fivefold greater risk of type 2 diabetes than boys, even after controlling for BMI and waist circumference (JAMA Pediatr. 2016 Aug 1. doi: 10.1001/jamapediatrics.2016.1971), reported Dr. Kimberly P. Newton and her coauthors.
The researchers also noted a significant association between nonalcoholic steatohepatitis (NASH) and glucose metabolism. Individuals with type 2 diabetes were three times more likely to also have NASH, while those with prediabetes had a 90% higher incidence of NASH, compared with individuals with normal glucose metabolism. They also found that those with NASH had significantly higher mean fasting glucose and insulin concentrations than children without NASH.
Dr. Newton, of the University of California, San Diego, and her coauthors wrote that while abnormal glucose metabolism is known to be common in adults with NAFLD, and that type diabetes is a risk factor for progression to NASH and liver-related mortality, the association in children with NAFLD is less well understood.
“Among our cohort, the prevalence of children with type 2 diabetes was much higher than would be expected based on contributions from obesity alone,” they wrote. “Although systemic insulin resistance is believed be important in the pathogenesis of both pediatric NAFLD and type 2 diabetes, to our knowledge, there are no longitudinal studies that evaluate the cause-effect relationship between these two associated conditions.”
The authors drew particular attention to the threefold higher odds of NASH in children with NAFLD and type 2 diabetes, pointing out that while the prognostic implications of NASH in childhood are not fully known, the NASH phenotype is associated with a “substantially” greater risk of cirrhosis. This risk is likely to be compounded by the presence of type 2 diabetes.
“Our study advances the literature by showing that as early as childhood, prediabetes and type 2 diabetes emerge as clear risk factors for NASH with potential downstream implications for future morbidity and mortality.”
Commenting on the greater incidence of prediabetes and type 2 diabetes among girls with NAFLD, the authors said this had been observed in other studies and that sex differences represented a major unmet research need.
The Nonalcoholic Steatohepatitis Clinical Research Network is supported by the National Institute of Diabetes and Digestive and Kidney Diseases. Additional support was received from the National Center for Advancing Translational Sciences. The researchers reported no conflicts of interest.

WHO analysis: Cost of new HCV meds unaffordable globally
The cost of new medicines for patients infected with hepatitis C virus vary widely around the globe, especially when adjusted for national wealth, results from an economic analysis led by World Health Organization officials suggest.
“These prices threaten the sustainability of health systems in many countries and prevent large-scale provision of treatment,” Suzanne Hill, PhD, of the World Health Organization, Geneva, and her associates wrote (PLoS Med. 2016 May 31;[5]:e1002032. doi:10.1371/journal.pmed.1002032).
“Stakeholders should implement a fairer pricing framework to deliver lower prices that take account of affordability. Without lower prices, countries are unlikely to be able to increase investment to minimize the burden of hepatitis C.”
In an effort to calculate the potential total cost of sofosbuvir and ledipasvir/sofosbuvir for different national health systems and individual patients in 30 countries, the researchers obtained 2015 prices for a 12-week course of treatment with the medications for as many countries as possible. Sources of reference were the Pharma Price Information service of the Austrian public health institute Gesundheit Österreich GmbH, national government and drug reimbursement authority website, and press releases.
Using data compiled between July 17, 2015, and Jan. 25, 2016, medication prices in Organisation for Economic Co-operation and Development (OECD) member countries and certain low- and middle-income countries were converted to U.S. dollars using period average exchange rates and were adjusted for purchasing power parity (PPP). “We analyzed prices compared to national economic performance and estimated market size and the cost of these drugs in terms of countries’ annual total pharmaceutical expenditure (TPE) and in terms of the duration of time an individual would need to work to pay for treatment out of pocket,” the researchers explained. “Patient affordability was calculated using 2014 OECD average annual wages, supplemented International Labour Organization median wages where necessary.”
Dr. Sullivan and her associates found that HCV medication prices varied significantly across countries, especially when adjusted for national wealth. For example, the median price of a 12-week course of sofosbuvir across 26 OECD countries was $42,017 in U.S. dollars, ranging from $37,729 in Japan to $64,680 in the United States. At the same time, countries in central and eastern Europe had higher PPP-adjusted prices, compared with other countries. For example, the PPP-adjusted prices of sofosbuvir in Poland and Turkey were $101,063 and $70,331, respectively, compared with a price of $64,680 in the Unite States. At the same time, the PPP-adjusted price of ledipasvir/sofosbuvir in Poland was $118,754, compared with a price of $72,765 in the United States.
The researchers also found that the PPP-adjusted price of a full course of sofosbuvir alone would be equivalent to at least 1 year of the PPP-adjusted average earnings for individuals in 12 of the 30 countries analyzed. In Poland, Slovakia, Portugal, and Turkey, a course of sofosbuvir alone would cost at least 2 years’ of average annual wages. “This analysis is conservative because prices were ex-factory prices with an assumed 23% price reduction, and did not include supply chain mark-ups and other costs such as the cost of diagnosis, daclatasvir, ribavirin, and health service costs,” they wrote.
They characterized the costs of sofosbuvir and ledipasvir/sofosbuvir as “not ‘affordable’ for most OECD countries at the nominal and PPP-adjusted prices, with Central and Eastern European countries being the most affected. While determining what is affordable or not is a value judgment, funding these treatments in these national health systems would consume large proportions of their TPE and increase pressure on existing budgets.”
They acknowledged certain limitations of the analysis, including the accuracy of the estimates of the numbers of people infected and of the price information that was accessible. “We have also not included all likely costs, such as the costs of combination treatment with ribavirin, other health care services, and increases in the duration of treatment in patients with cirrhosis; thus, our budget impact estimates are underestimates of the cost of treatment. We are also aware that in some countries, the prices are probably lower than the publicly accessible prices because of confidential discounts or rebates negotiated with the manufacturer.”

The savings to the medical system in averted future costs of liver complications were excluded from the assessment developed by Suzanne Hill, PhD, and her colleagues. However, studies of the cost-effectiveness of HCV therapies in the United States suggest that these benefits are substantial and can help finance HCV treatment.
Despite the discounts offered in both LMICs (low- and middle-income countries) and OECD (Organisation for Economic Cooperation and Development) countries, the short-term impact of HCV treatment on budgets of health care payers and individuals may limit access. However, there are two mitigating factors. First, once the backlog of prevalent cases is treated, the budgetary impact drops dramatically, as only the relatively few incident cases need be treated. Thus, while fiscally disruptive if all HCV-infected persons were immediately put on treatment, that disruption would last only 1 year. Second, treating everyone in year 1 is implausible. The process of identifying cases, limits to health care system capacity, and patient preferences all suggest a multi-year catch-up process. For those reasons, the fiscal burden expressed as a percent of TPE (total pharmaceutical expenditure) or as a portion of the average annual wage would be much less than the maximum burden as presented in Dr. Hill’s article.
One solution, then, is to spread the upfront cost of treatment over several years. Not everyone is eager to be treated, especially the asymptomatic for whom delay may be less harmful. Beyond this, there are options for phasing in treatment gradually by equity concerns, i.e., treating those with lower access to care first, or by disease stage. Our U.S.-based analysis found that while treating all patients in fibrosis stages 1–4 was cost-effective, initiating treatment in stages 3 and 4 was more cost-effective and would reduce total net treatment costs in the United States by about one-third per individual with chronic hepatitis C. A combination of equity and disease stage criteria can match phase-in plans to different countries’ budgets and political will.
It is in each country’s capacity, and without disruptive budgetary impact, to start treating many of those most in need of care now and to extend coverage to all over the succeeding few years.

Hepatitis Outlook: June 2016
If you work on the front lines of medical care treating patients with hepatitis, you may not have time to review all the hepatitis research that enters the medical literature every month. Here’s a quick look at some notable news items and journal articles published over the past month, covering a variety of the major hepatitis viruses.
Identification of a case of acute hepatitis C virus (HCV) infection in a frequent blood donor without other risk factors should be considered a sentinel event and should prompt public health investigation, according to research published in Morbidity and Mortality Weekly Report, because this could indicate a possible health care–associated infection.
Negative media reports about the safety of the hepatitis B vaccine in China harmed perception of the vaccine’s safety among patients, according to a recent study. Although the reports were erroneous, the failure of public health departments to communicate effectively contributed to a rise in the number of parents refusing to vaccinate their children.
An experimental, highly specific and sensitive HCV core antigen enzyme immunoassay (HCV-Ags EIA) was found to have the lowest limit of detection equivalent to serum HCV RNA levels of 150-250 IU/mL. Investigators found that the HCV-Ags EIA reliably differentiated viremic HCV infection from resolved HCV infection, thus accomplishing screening and diagnosis of viremic HCV infection in one step.
Loss of confidence in the hepatitis B vaccine following disproved allegations that the vaccine caused multiple sclerosis persists in France, according to research published in Human Vaccines & Immunotherapeutics.
The approval of the direct-acting antiviral agents (DAAs) grazoprevir and elbasvir with an indication for all levels of kidney function and dialysis has altered the landscape for the treatment of hepatitis C virus in patients with chronic kidney disease, according to a review in Clinical Liver Disease. The authors say this is because other DAAs are either not approved for use in patients with advanced chronic kidney disease or no safety data are available for the dialysis population.
A study in the Journal of Viral Hepatitis found that insulin resistance was associated with an increased risk for loss of vaccine-acquired anti-HBs (hepatitis B surface antigen) in a large sample of a nondiabetic, general population, indicating a possible role of insulin resistance in vaccine-induced immunity.
Grazoprevir, a second-generation HCV NS3/4A protease inhibitor, combined with ribavirin was associated with a rapid and sustained suppression of HCV RNA in a randomized study. The authors said the results support further evaluation of grazoprevir-based treatment regimens.
HIV–HCV coinfected patients treated with a fixed-dose combination of ledipasvir and sofosbuvir (LDV/SOF) showed significant improvement of their health-related quality of life and other patient-reported outcomes during treatment and after treatment cessation, according to a study in the Journal of Viral Hepatitis.
A Swedish study found that diabetes mellitus and cirrhosis are strong risk factors for hepatocellular carcinoma development after sustained virologic response (SVR) following treatment for chronic HCV has been achieved. However, the risk to develop hepatocellular carcinoma diminished significantly 2 years after SVR.
Chinese investigators said serum levels of platelet-derived growth factor (PDGF) decreased remarkably through fibrosis progression and could be used as a noninvasive biomarker for the assessment of fibrosis stage in patients with chronic hepatitis B virus (HBV).
A genome-wide association study of liver fibrosis progression in patients coinfected with HCV and HIV identified a new locus associated with fibrosis severity on chromosome 3p25. The authors said the results may help define new targets for drug development or new prognostic tests.
The RNA helicase DDX5 and E3 ligase Mex3b are important cellular targets for the design of novel, epigenetic therapies to combat HBV infection and poor-prognosis HBV-associated liver cancer, according to a study in Hepatology.
A Japanese study found that daclatasvir (DCV) and asunaprevir (ASV) dual therapy in hemodialysis patients infected with HCV is effective and safe with similar results, compared with patients with normal renal function.
A study evaluating the antiviral effect of ribavirin priming, and its influence on sustained virologic response after combination treatment, found that the lowest response pattern in HCV-infected patients was observed in prior nonresponder patients to pegylated interferon-alfa plus ribavirin combination therapy. The authors said this suggests that not only the individual interferon, but also the ribavirin sensitivity contributes significantly to the nonresponsive state.
A veterinary study provided evidence that hepatitis E virus is able to damage the blood-brain barrier and replicate in the brain and spinal cord.
An all-oral regimen of ledipasvir and sofosbuvir is an effective and safe treatment for a wide range of HCV genotype 4 subtypes in both treatment-naive and -experienced patients, including those with compensated cirrhosis, according to results of a recent study.

Chinese investigators said serum levels of platelet-derived growth factor (PDGF) decreased remarkably through fibrosis progression and could be used as a noninvasive biomarker for the assessment of fibrosis stage in patients with chronic hepatitis B virus (HBV).
A genome-wide association study of liver fibrosis progression in patients coinfected with HCV and HIV identified a new locus associated with fibrosis severity on chromosome 3p25. The authors said the results may help define new targets for drug development or new prognostic tests.
The RNA helicase DDX5 and E3 ligase Mex3b are important cellular targets for the design of novel, epigenetic therapies to combat HBV infection and poor-prognosis HBV-associated liver cancer, according to a study in Hepatology.
A Japanese study found that daclatasvir (DCV) and asunaprevir (ASV) dual therapy in hemodialysis patients infected with HCV is effective and safe with similar results, compared with patients with normal renal function.
A study evaluating the antiviral effect of ribavirin priming, and its influence on sustained virologic response after combination treatment, found that the lowest response pattern in HCV-infected patients was observed in prior nonresponder patients to pegylated interferon-alfa plus ribavirin combination therapy. The authors said this suggests that not only the individual interferon, but also the ribavirin sensitivity contributes significantly to the nonresponsive state.
A veterinary study provided evidence that hepatitis E virus is able to damage the blood-brain barrier and replicate in the brain and spinal cord.
An all-oral regimen of ledipasvir and sofosbuvir is an effective and safe treatment for a wide range of HCV genotype 4 subtypes in both treatment-naive and -experienced patients, including those with compensated cirrhosis, according to results of a recent study.

Early sustained viral response linked to better outcomes among HCV patients
Among patients with hepatitis C virus infection who were in compensated cirrhosis, sustained viral response was associated with significantly lower rates of liver decompensation, hepatocellular carcinoma, and liver-related death, even in the presence of clinically meaningful portal hypertension.
But patients in stage 2 cirrhosis were more likely than were stage 1 patients to develop liver decompensation and to die of hepatocellular carcinoma, regardless of SVR, said Dr. Vito Di Marco and his associates at the University of Palermo, Italy. “The available evidence, including our own, suggests that it is opportune to treat HCV as early as possible, in order to reduce progression to stages of cirrhosis in which a viral cure may be less likely lead to ultimate achievement of a major benefit,” they wrote. The report is in the July issue of Gastroenterology.
Clinically significant portal hypertension causes esophageal varices, a “landmark” indicator of stage 2 cirrhosis, the researchers noted. To parse the effects of SVR by cirrhosis stage, they followed all 444 HCV patients with compensated cirrhosis who were treated with pegylated interferon a2b and ribavirin at their tertiary liver centers between 2001 and 2009 (Gastroenterology 2016 March 31. doi: 10.1053/j.gastro.2016.03.036).
The cohort included 218 patients without esophageal varices (that is, patients in stage 1 cirrhosis) and 226 patients with esophageal varices (stage 2 cirrhosis), the researchers said. The groups were demographically similar at baseline, and had similar body mass indices and rates of comorbidities. Rates of SVR were 31% for patients in stage 1 cirrhosis and 18% for patients in stage 2 cirrhosis (P = .003).
Among stage 1 patients, achieving SVR was associated with a lower risk of liver decompensation (0% versus 7%; P = .009), a lower annual rate of hepatocellular carcinoma (0.7% versus 2.9%; P = .002), and a lower risk of liver-related death (3% versus 12%; P = .03). Stage 1 cirrhosis patients also were about 75% less likely to develop esophageal varices if they achieved SVR than if they did not (hazard ratio [HR], 0.23; 95% confidence interval [CI], 0.11 to 0.48; P less than .001).
Eradicating HCV infection also was associated with better clinical outcomes among patients in stage 2 cirrhosis, according to the investigators. For example, those who achieved SVR had a 0.9% annual rate of hepatocellular carcinoma, compared with 3.6% for those who did not (P = .002). And only 2% of stage 2 patients who achieved SVR died from hepatocellular carcinoma, compared to 18% of those who did not (P = .003).
But regardless of SVR, patients with stage 2 cirrhosis were nearly three times more likely to develop liver compensation (HR, 2.8; 95% CI, 1.73 to 4.59) and about 1.75 times more likely to die of liver-related causes (HR, 1.77; 95% CI, 1.12 to 2.80) compared with patients in stage 1 cirrhosis, the investigators emphasized. Also, achieving SVR did not prevent stage 2 patients from developing more esophageal varices (HR, 1.58; 95% CI, 0.33 to 1.03).
The researchers acknowledged several study limitations. “We have performed many comparisons with respect to multiple endpoints, which could have increased the likelihood of inference errors that can result from multiple comparisons,” they wrote. “Furthermore, we cannot exclude the lack of power as an explanation for some of our results.” In addition, pegylated interferon–based therapies have low rates of SVR, and the study was limited to patients who could tolerate the regimen, they added. Nonetheless, the results indicate that eradicating HCV is clinically beneficial even in advanced compensated cirrhosis, but that early treatment helps maximize these outcomes, they concluded. “Pegylated interferon–free direct-acting antiviral combo regimens will ultimately increase the rate of virological cure to almost universal effectiveness,” they added. “It remains to be assessed whether the effectiveness of these new regimens will be automatically translated into a universal clinical benefit.”

VIDEO: Nearly half of Medicaid patients denied antivirals for HCV
State Medicaid programs denied nearly half of requests to cover direct-acting antiviral drugs for patients with chronic hepatitis C virus (HCV) infection, according to a prospective study of beneficiaries in Delaware, Maryland, New Jersey, and Pennsylvania reported in the July issue of Clinical Gastroenterology and Hepatology.
In contrast, only 5% of Medicare patients and 10% of privately insured patients were denied coverage, said Dr. Vincent Lo Re III of the University of Pennsylvania, Philadelphia, together with his associates. “Notably, nearly one-quarter of Medicaid recipients with cirrhosis experienced treatment denial. Medicaid patients from these states also experienced a longer time to prescription fill than those with Medicare or commercial insurance,” the researchers said.
Their study included 2,321 HCV patients prescribed a direct-acting antiviral regimen between November 1, 2014 and April 30, 2015. All prescriptions were submitted to a specialty pharmacy that serves HCV patients in Maryland, Pennsylvania, Delaware, and New Jersey, the investigators noted. They focused on “absolute denial,” meaning that the prescription was never filled because the insurer denied coverage, regardless of appeals. “Data are lacking on the incidence of absolute denial of direct-acting antiviral prescriptions and factors associated with this outcome,” the investigators said. “These data are important because absolute denial of HCV treatment by insurers might have adverse outcomes on patients and could harm patient-provider relationships” (Clin Gastroenterol Hepatol. 2016 Apr 5. doi: 10.1016/j.cgh.2016.03.040).

A total of 1,023 study patients were privately insured, 795 were enrolled in Medicare, and 503 were Medicaid patients, according to the researchers. In all, 377 patients (16%) received absolute denials, most often because of “insufficient information to assess medical need” (36% of denials) and “lack of medical necessity” (35%). Medicaid patients faced an absolute denial rate of 46% – significantly higher than rates for private insurers (10.5%) or Medicare (5%; P less than .001 for both comparisons). After adjusting for potential confounders, Medicaid patients were more than four times as likely to be denied coverage for direct-acting antivirals, compared with privately insured patients (relative risk, 4.1; 95% confidence interval, 3.4-5.1). Delaware’s Medicaid program had the highest rate of absolute denial (57%), followed by Pennsylvania (48%), Maryland (47%), and New Jersey (37%).
Medicaid programs even refused to cover direct-acting antiviral prescriptions for 25% of patients who had cirrhosis, compared with absolute denial rates of only 1% for Medicare and 3% of private insurers (P less than .001 for both comparisons), according to the researchers. The implications of these denials “remain unknown,” but lack of treatment increases the risk of end-stage liver disease, hepatocellular carcinoma, extrahepatic disease, HCV transmission, and “anxiety and stress about HCV disease progression, [which can] provoke distrust among patients of the health care system and their providers,” they added. “Clinicians then are challenged to explain the denial, and important opportunities for patient engagement, education, and cure could be irrevocably lost.”
Medicaid programs also initially denied about 25% of prescriptions before eventually approving them, despite the fact that “patients had complete prior authorization requests that should have contained the materials needed to justify approval,” said the investigators. Furthermore, denial letters usually did not specify the information that was needed, “making it difficult [for clinicians] to appeal the decision.” In contrast, only about 8% of privately insured patients and 13% of Medicare enrollees were initially denied coverage.
Prescriptions as a whole were more likely to be filled in the last 3 months of the study than earlier, perhaps because insurers are starting to relax their reimbursement criteria, said the investigators. Indeed, in October 2015, the American Association for the Study of Liver Diseases and the Infectious Disease Society of America stopped triaging groups of patients for direct-acting antiviral therapy, they noted.
The research was supported by the Penn Center for AIDS Research, which is funded by the National Institutes of Health. Dr. Lo Re received investigator-initiated research support from AstraZeneca. Five coinvestigators reported relationships with a number of pharmaceutical companies. Four coinvestigators reported employment by the study site, Burman’s Specialty Pharmacy.

FDA approves Epclusa for patients with chronic hepatitis C
Adult patients with chronic hepatitis C virus (HCV) both with and without cirrhosis can now be prescribed Epclusa. The Food and Drug Administration approved the fixed-dose combination tablet is the first treatment that controls genotypes 1-6 of HCV.
“This approval offers a management and treatment option for a wider scope of patients with chronic hepatitis C,” said Edward Cox, MD, director of the Office of Antimicrobial Products in the FDA’s Center for Drug Evaluation and Research.
Epclusa, which contains sofosbuvir and velpatasvir, is manufactured by Gilead Sciences, located in Foster City, Calif. Before approval, the drug was evaluated for 12 weeks in three phase III clinical trials that included 1,558 patients diagnosed without cirrhosis and patients with compensated cirrhosis. Twelve weeks after finishing treatment, 95%-99% of patients who received Epclusa had no signs of infection. Epclusa cured the condition, which means no sign of the virus was detected in any of the patients’ blood. In addition, 267 patients were studied for the safety and efficacy of Epclusa, 87 of whom took Epclusa in combination with ribavirin for 12 weeks, and 94% of these patients had no virus detected in the blood 12 weeks after finishing treatment.
Side effects of Epclusa include headache and fatigue. Epclusa also carries a warning not to use with certain drugs that may reduce the effective amount of Epclusa.
