Global, regional, and national burden of primary liver cancer attributable to metabolic risks: an analysis of the Global Burden of Disease Study 1990-2021.

Background: The global burden of metabolic diseases is increasing, but estimates of their impact on primary liver cancer are uncertain. We aimed to assess the global burden of primary liver cancer attributable to metabolic risk factors, including high body mass index (BMI) and high fasting plasma glucose (FPG) levels, between 1990 and 2021.

Methods: The total number and age-standardized rates of deaths and disability-adjusted life years (DALYs) from primary liver cancer attributable to each metabolic risk factor were extracted from the Global Burden of Disease Study 1990-2021.

Autoimmune gastritis studies and gastric cancer: True renaissance or bibliometric illusion.

A bibliometric analysis of studies dedicated to autoimmune gastritis (AIG) recently published demonstrated a noteworthy surge in publications over the last three years. This can be explained by numerous publications from different regions of the world reporting the results of several studies that stimulated reassessment of our view of AIG as a precancerous condition. Follow-up studies and retrospective analyses showed that the risk of gastric cancer (GC) in AIG patients is much lower than expected if the patients ever being infected with () were excluded.

Nonalcoholic Fatty Liver Disease: Disease Burden and Disease Awareness.

Nonalcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease worldwide and has been implying an unprecedented burden to health care systems. The prevalence of NAFLD has exceeded 30% in developed countries. Considering the asymptomatic nature of undiagnosed NAFLD, high suspicion and noninvasive diagnosis have utmost importance especially in primary care level.

Clinical and patient-reported outcome profile of patients with hepatitis B viral infection from the Global Liver Registry™.

Chronic hepatitis B (CHB) infection is one of the most common causes of cirrhosis and liver cancer worldwide. Our aim was to assess clinical and patient-reported outcome (PRO) profile of CHB patients from different regions of the world using the Global Liver Registry. The CHB patients seen in real-world practices are being enrolled in the Global Liver Registry.

Severe impairment of patient-reported outcomes in patients with chronic hepatitis C virus infection seen in real-world practices across the world: Data from the global liver registry.

Cure of chronic hepatitis C (CHC) can lead to improvement of health-related quality of life and other patient-reported outcomes (PROs). While extensive PRO data for CHC patients who were enrolled in clinical trials are available, similar data for patients seen in real-world practices are scarce. Our aim was to assess PROs of CHC patients enrolled from real-world practices from different regions and to compare them with those enrolled in clinical trials.

Elimination of HCV in Russia: Barriers and Perspective.

Hepatitis C virus (HCV) is highly prevalent in Russia, representing the largest pool of hepatitis C patients in Europe. Effective treatment regimens with direct-acting antivirals can achieve HCV cure in all patients; therefore, in 2016 the World Health Organization proposed eliminating hepatitis C as a public health threat by 2030. However, only a small number of countries are on track to meet the WHO's hepatitis C elimination targets by 2030 due to many barriers in healthcare systems.

Clinical and Patient-Reported Outcomes From Patients With Nonalcoholic Fatty Liver Disease Across the World: Data From the Global Non-Alcoholic Steatohepatitis (NASH)/ Non-Alcoholic Fatty Liver Disease (NAFLD) Registry.

Background & Aims: Globally, nonalcoholic fatty liver disease (NAFLD) is a common cause of chronic liver disease. We assessed the clinical presentation and patient-reported outcomes (PROs) among NAFLD patients from different countries.

Methods: Clinical, laboratory, and PRO data (Chronic Liver Disease Questionnaire-nonalcoholic steatohepatitis [NASH], Functional Assessment of Chronic Illness Therapy-Fatigue, and the Work Productivity and Activity Index) were collected from NAFLD patients seen in real-world practices and enrolled in the Global NAFLD/NASH Registry encompassing 18 countries in 6 global burden of disease super-regions.

Elbasvir/Grazoprevir for HCV Infection in Russia: A Randomized Trial.

Purpose: Hepatitis C virus (HCV) infection is a major healthcare concern in Russia, where almost 5 million individuals are viremic. Elbasvir/grazoprevir is a fixed-dose combination therapy for the treatment of HCV genotype 1 and genotype 4 infection. The present analysis aimed to assess the safety and efficacy of elbasvir/grazoprevir in individuals with HCV infection enrolled at Russian study sites in the C-CORAL study.

Alcohol-Related Liver Disease Is Rarely Detected at Early Stages Compared With Liver Diseases of Other Etiologies Worldwide.

Background & Aims: Despite recent advances in treatment of viral hepatitis, liver-related mortality is high, possibly owing to the large burden of advanced alcohol-related liver disease (ALD). We investigated whether patients with ALD are initially seen at later stages of disease development than patients with hepatitis C virus (HCV) infection or other etiologies.

Methods: We performed a cross-sectional study of 3453 consecutive patients with either early or advanced liver disease (1699 patients with early and 1754 with advanced liver disease) seen at 17 tertiary care liver or gastrointestinal units worldwide, from August 2015 through March 2017.

Sofosbuvir/velpatasvir for the treatment of HCV: excellent results from a phase-3, open-label study in Russia and Sweden.

Background: In both Russia and Sweden, the dominant hepatitis C virus (HCV) is genotype 1, but around one-third of patients have genotype 3 infection. For such countries, HCV genotype testing is recommended prior to therapy. An effective pangenotypic therapy may potentially eliminate the need for genotyping.

Efficacy and safety of elbasvir/grazoprevir in participants with hepatitis C virus genotype 1, 4, or 6 infection from the Asia-Pacific region and Russia: Final results from the randomized C-CORAL study.

Background And Aim: Although treatment with direct-acting antivirals has dramatically improved morbidity and mortality attributable to chronic hepatitis C virus infection, universal access to these medicines has been slow in the Asia-Pacific region and Russia. This study evaluated efficacy and safety of elbasvir/grazoprevir in participants with hepatitis C virus infection from Asia-Pacific countries and Russia (C-CORAL).

Methods: C-CORAL was a phase 3, randomized, placebo-controlled study (NCT02251990).

Fiber-enriched diet helps to control symptoms and improves esophageal motility in patients with non-erosive gastroesophageal reflux disease.

Aim: To investigate the effect of dietary fiber on symptoms and esophageal function testing parameters in non-erosive gastroesophageal reflux disease (GERD) (NERD) patients.

Methods: Thirty-six NERD patients with low (< 20 g/d) dietary fiber intake were enrolled in the study. They were examined with the use of symptom questionnaire (GERD-Q), high-resolution esophageal manometry, 24-h esophageal pH-impedance examinations, and food frequency questionnaire before and after 10 d of usual diet supplemented by psyllium 5.

Ombitasvir/paritaprevir/ritonavir+dasabuvir+ribavirin for chronic hepatitis C virus genotype 1b-infected cirrhotics (TURQUOISE-IV).

Objective: An estimated 336 per 100 000 people in Russia are infected with hepatitis C virus, including up to 75% with genotype (GT) 1b. In the TURQUOISE-II/-III trials, a 12-week regimen of the direct-acting antiviral agents ombitasvir (OBV), paritaprevir (PTV), ritonavir, and dasabuvir (DSV) in GT1b-infected patients with compensated cirrhosis resulted in 12-week sustained virologic response (SVR) rates of 100%.

Patients And Methods: In TURQUOISE-IV, GT1b-infected patients (n=36) from Russia and Belarus with compensated cirrhosis, who were treatment naive or previously treated with pegylated interferon/ribavirin (RBV), received OBV/PTV/ritonavir+DSV+RBV for 12 weeks.

Elbasvir/grazoprevir in Asia-Pacific/Russian participants with chronic hepatitis C virus genotype 1, 4, or 6 infection.

The prevalence of hepatitis C virus (HCV) infection in Asian countries is high. This study assessed the efficacy and safety of elbasvir/grazoprevir (EBR/GZR) in participants with HCV infection from Asia-Pacific countries and Russia. In this phase 3, randomized, placebo-controlled, double-blind study, treatment-naive participants with HCV genotype (GT) 1, 4, or 6 infection were randomized to EBR 50 mg/GZR 100 mg (immediate-treatment group [ITG]) or placebo (deferred-treatment group [DTG]) once daily for 12 weeks (Protocol PN-5172-067, NCT02251990).

Ledipasvir-Sofosbuvir for 8 Weeks in Non-Cirrhotic Patients with Previously Untreated Genotype 1 HCV Infection ± HIV-1 Co-Infection.

Unlabelled: BACKGROUND AND OBJECTIVES: The efficacy of < 12 weeks of hepatitis C virus (HCV) treatment in patients co-infected with HCV and human immunodeficiency virus type 1 (HIV-1) has not been established. We assessed the efficacy and safety of ledipasvir-sofosbuvir for 8 weeks in HCV mono-infected and HCV/HIV-1 co-infected patients.

Methods: We enrolled patients mono-infected with genotype 1 HCV or co-infected with HCV and HIV-1 who were HCV treatment-naive and did not have cirrhosis.

Daclatasvir/asunaprevir/beclabuvir, all-oral, fixed-dose combination for patients with chronic hepatitis C virus genotype 1.

Background And Aim: This multinational (Taiwan, South Korea, Russia) phase 3 study evaluated the all-oral, ribavirin-free, fixed-dose combination (DCV-TRIO) of daclatasvir (NS5A inhibitor) 30 mg, asunaprevir (NS3 inhibitor) 200 mg, and beclabuvir (NS5B inhibitor) 75 mg, in patients with chronic hepatitis C virus genotype-1 infection, with or without compensated cirrhosis.

Methods: UNITY-4 (NCT02170727) was an open-label, two-cohort study in which 169 patients, treatment-naive (n = 138) or treatment-experienced (n = 31), received twice-daily DCV-TRIO for 12 weeks with 24 weeks of post-treatment follow-up. The primary efficacy end point was sustained virologic response at post-treatment week 12 (SVR12) in treatment-naive patients.

Late Relapse Versus Hepatitis C Virus Reinfection in Patients With Sustained Virologic Response After Sofosbuvir-Based Therapies.

Background:  The development of direct-acting antivirals in recent years has dramatically enhanced rates of viral eradication to >90% in patients with chronic hepatitis C virus (HCV) infection. To determine true treatment efficacy and define the most appropriate retreatment, it is important to distinguish virologic relapse from reinfection when patients in whom HCV is eradicated during treatment become infected with a new HCV strain after treatment.

Methods:  We investigated the prevalence of late recurrent viremia (patients with sustained virologic response 12 weeks after the end of treatment but detectable HCV RNA at follow-up week 24) and used refined phylogenetic analysis of multiple HCV genes to distinguish virologic relapse from reinfection.

Efficacy of sofosbuvir plus ribavirin in treatment-naive patients with genotype-1 and -3 HCV infection: results from a Russian Phase IIIb study.

Background: In this Phase IIIb study, we evaluated the efficacy and safety of the oral nucleotide analogue inhibitor sofosbuvir plus ribavirin, with special attention given to viral resistance, in Russian patients with HCV genotype-1 or -3.

Methods: Treatment-naive patients with and without compensated cirrhosis were randomized (1:1) to receive 16 or 24 weeks of once-daily sofosbuvir 400 mg plus twice-daily oral ribavirin 1,000 or 1,200 mg/day. The primary efficacy end point was the proportion of patients with sustained viral response 12 weeks after the end of treatment (SVR12).
