AIM: To investigate peg-interferon (peg-IFN) and ribavirin (RBV) therapy in Myanmar and to predict sustained virologic response (SVR). METHODS: This single-center, open-label, study was conducted in Myanmar between 2009 and 2014. A total of 288 patients infected with HCV genotypes 1, 2, 3 and 6 were treated with peg-IFN alpha-2a (180 μg/wk) or alpha-2b (50 to 100 μg as a weight-based dose) and RBV as a weight-based dose (15 mg/kg/d). Treatment duration was 48 wk for genotypes 1 and 6, 24 wk for genotype 2, and 24 or 48 wk for genotype 3 based on rapid virologic response (RVR)...

We report a 40-year-old man with end-stage renal disease due to IgA nephropathy who underwent deceased donor kidney transplantation. The donor was diagnosed to be brain-dead due to cerebral hemorrhage after her second liver transplantation for non-viral liver cirrhosis. Intraoperative 1-hour biopsy of the graft kidney revealed moderate global glomerular sclerosis (22%) and interstitial fibrosis (40%) consistent with underlying nephrosclerosis or calcineurin inhibitor nephrotoxicity. Although hemodialysis was needed until the graft began functioning several days after the kidney transplantation, the postoperative clinical course thereafter was uneventful and the graft functioned well with stable serum creatinine levels around 2...

Airway remodeling is resultant of a complex multi-cellular response associated with a progressive decline of pulmonary function in patients with chronic airway disease. Here, repeated infections with respiratory viruses are linked with airway remodeling through largely unknown mechanisms. Although acute activation of the Toll like receptor (TLR)3 pathway by extracellular poly(I:C) induces innate signaling through the NFkB transcription factor in human small airway epithelial cells (hSAECs), prolonged (repetitive or tonic) poly(I:C) stimulation produces chronic stress fiber formation, mesenchymal transition and activation of a fibrotic program...

INTRODUCTION: The pathogenesis of non-alcoholic fatty liver disease (NAFLD) is multifactorial including metabolic, genetic (e.g. PNPLA3 [patatin-like phospholipase domain-containing 3 gene]), viral factors and drugs. Besides, there is evidence for a role of copper deficiency. Aim of the study was to evaluate the role of hepatic copper content, PNPLA3 in NAFLD patients with and without metabolic syndrome (MetS). METHODS: One-hundred seventy-four NAFLD patients, who underwent liver biopsy for diagnostic work-up, were studied...

This review focuses on microRNAs (miRs) in cardiac surgery, where they are emerging as potential targets for therapeutic intervention as well as novel clinical biomarkers. Identification of the up/down-regulation of specific miRs in defined groups of cardiac surgery patients can lead to the development of novel strategies for targeted treatment in order to maximise therapeutic results and minimise acute, delayed or chronic complications. MiRs could also be involved in determining the outcome independently of complications, for example in relation to myocardial perfusion and fibrosis...

In the respiratory tract, viruses and bacteria can interact on multiple levels. It is well known that respiratory viruses, particularly influenza viruses, increase the susceptibility to secondary bacterial infections. Numerous mechanisms, including compromised physical and immunological barriers, and changes in the microenvironment have hereby been shown to contribute to the development of secondary bacterial infections. In contrast, our understanding of how bacteria shape a response to subsequent viral infection is still limited...

BACKGROUND: Treatment of HCV/HIV coinfection is now largely based upon utilization of direct acting agents. Pre-treatment viral resistant-associated variants (RAVs) and host liver condition may affect the sustained virological response. In this study, we explored relative prevalence of protease resistance-associated mutations, the evolution of those RAVs following 12 weeks of pegylated interferon alfa exposure, and the role hepatic fibrosis might have on RAV display. METHODS: Thirty nonresponder HCV/ HIV coinfected subjects were evaluated pre- and post- 12 weeks of pegIFN treatment...

BACKGROUND AND AIMS: Antiviral therapy for patients with hepatitis B (HBV) infection is generally deferred for "immune inactive" patients, although longitudinal changes in viral load and liver fibrosis remain understudied in this population. Likewise, in treated patients, the temporal relationship between changes in viral load and liver fibrosis is not well-characterized. Using data from the Chronic Hepatitis Cohort Study, we investigated viral load and the Fibrosis-4 index (FIB4, a serum-based marker of liver fibrosis) trajectories in both untreated and treated HBV patients...

BACKGROUND: Cystic fibrosis is a degenerative disease characterized by progressive epithelial secretory gland dysfunction associated with repeated respiratory infections. Bacterial infections are very frequent in children with cystic fibrosis, but because rapid METHODS: for screening for the wide variety of potentially involved viruses were unavailable until recently, the frequency of viral presence is unknown. Multiplex PCR enables screening for many viruses involved in respiratory infections...

Hepatocellular carcinoma (HCC) is the second most common cause of cancer-related death in the world. Radical treatment of HCC in early stages results in a long disease-free period and improved overall survival. The choice of optimal management strategy for HCC mainly depends on the severity of the underlying liver disease. For patients with decompensated liver cirrhosis and HCC within Milan criteria (MC), liver transplant (LT) is the choice of treatment. However, for patients with good residual liver reserve and HCC within MC, selection of other curative treatments such as liver resection (LR) or radiofrequency ablation may be a reasonable alternative...

Hepatocellular carcinoma (HCC) is the most common form of liver cancer and has a poor prognosis and a low survival rate; its incidence is on the rise. Hepatitis B virus (HBV) infection is one of the main causes of HCC. A high prevalence of pre-S deletions of HBV surface antigen, which encompass T-cell and/or B-cell epitopes, is found in HBV carriers; antiviral therapy and viral immune escape may cause and select for these HBV mutants. In particular, the presence of pre-S2 deletion mutants is an important risk factor associated with cirrhosis and HCC...

: Lantibiotics are ribosomally synthesized and post-translationally modified antimicrobial peptides that are characterized by the thioether cross-linked bisamino acids lanthionine (Lan) and methyllanthionine (MeLan). Duramycin contains 19 amino acids including one Lan and two MeLan, an unusual lysinoalanine (Lal) bridge formed from the ϵ-amino group of lysine 19 and a serine residue at position 6, and an erythro-3-hydroxy-L-aspartic acid at position 15. These modifications are important for the interactions of duramycin with its biological target phosphatidylethanolamine (PE)...

During the last 5 years, the availability of direct-acting antiviral (DAA) agents has revolutionized the treatment of hepatitis C virus (HCV). Compared with interferon/ribavirin-the previous standard of care-DAA combination regimens offer improved sustained virological response (SVR) rates, shorter treatment durations of 8-24 weeks, convenient once-daily single-tablet formulations and more favourable tolerability profiles. HCV treatment is complex, and the choice of therapy must consider a complex range of factors, including baseline viral load, fibrosis stage, the HCV genotype and subgenotype, and the presence of resistance-associated substitutions at baseline...

We have recently shown that non-viral gene therapy can stabilise the decline of lung function in patients with cystic fibrosis (CF). However, the effect was modest, and more potent gene transfer agents are still required. Fuson protein (F)/Hemagglutinin/Neuraminidase protein (HN)-pseudotyped lentiviral vectors are more efficient for lung gene transfer than non-viral vectors in preclinical models. In preparation for a first-in-man CF trial using the lentiviral vector, we have undertaken key translational preclinical studies...

: Hepatitis C virus (HCV) infects 2-3% of the world population and is a leading cause of liver diseases such as fibrosis, cirrhosis and hepatocellular carcinoma. Many aspects of HCV study, ranging from molecular virology, antiviral drug development and drug resistance profiling, were supported by straightforward assays of HCV replication and infection. Among these assays, HCV-dependent fluorescence relocalization (HDFR) system allows live-cell visualization of infection without modifying viral genome, but this strategy required careful recognition of fluorescence relocalization pattern for its high fluorescence background in cytoplasm...

To study the beneficial effects of ivabradine in dilated cardiomyopathy (DCM) mice, which evolved from coxsackievirus B3-induced chronic viral myocarditis. Four-to-five-week-old male balb/c mice were inoculated intraperitoneally with coxsackievirus B3 (Strain Nancy) on days 1, 14, and 28. The day of the first virus inoculation was defined as day 1. Thirty-five days later, the surviving chronic viral myocarditis mice were divided randomly into two groups, a treatment group and an untreated group. Ivabradine was administered by gavage for 30 consecutive days in the treatment group, and the untreated group was administered normal saline...
