Objectives: There are different approaches for treating recurrent hepatitis C viral infection after a liver transplant. However, sustained virologic response is achieved in < 40% of infected allografts. We examined sustained virologic response improvement using a prolonged course of peginterferon and aggressive use of ribavirin.
Patients And Methods: From October 1998 to May 2008, 24 patients (13 male, 11 female; mean age at transplant, 49.4 +/- 7.7 years) received a prolonged course of peginterferon and ribavirin (range, 48-180 weeks). The mean interval from liver transplant to hepatitis C antiviral therapy was 26.6 +/- 27.8 months. Patients began weight-based standard dosages of peginterferon and ribavirin. In case of hemolysis, patients were treated with Epogen, with and without blood transfusions.
Results: Fourteen patients (58.3%) had an end of treatment response, and 8 patients (33.3%) maintained sustained virologic response after the first course of therapy. Of 10 patients who did not respond to the first course, 6 received an extended course of antiviral therapy after a mean of 15 +/- 4.6 weeks from completion of first course. Five of these 6 patients achieved end of treatment response and maintained a sustained virologic response, resulting in an overall end of treatment response in 17 patients and a sustained virologic response in 13 patients. Twenty-two patients experienced hemolysis and were treated with Epogen. Fifteen patients received blood transfusions. Ribavirin dosage was reduced in 12 patients, and peginterferon dosage was reduced in 2 patients.
Conclusions: Aggressive use of ribavirin and prolonged course of peginterferon provided sustained virologic response in 54.1% of liver transplant recipients with recurrent hepatitis C virus-infection. More prospective studies are warranted to evaluate the benefit of this approach fully.

The barley stripe mosaic virus (BSMV) uses its genomic RNA components (alpha, beta, and gamma) as an efficient method for studying gene functions. It is a newly developed method that utilizes gene transcript suppression to determine the role of plant genes. BSMV derived from virus induced gene silencing (VIGS) is capable of infecting various key farming crops like barley, wheat, rice, corn, and oats.

The emergence of antibiotic-resistant pathogens necessitates alternative therapies for treating microbial infections, especially in the oral cavity and upper respiratory tract. Our team has developed Phage Pastilles, a controlled-release formulation containing bacteriophages that target common pathogens, including Streptococcus pyogenes, Streptococcus salivarius, Staphylococcus aureus, Enterococcus faecalis, and E. coli.

Despite the availability of a highly efficacious vaccine, a global resurgence of measles infections has occurred, largely due to decreased vaccination coverage and waning immunity following the two-dose vaccination schedule. This study aims to assess the cellular immune response in individuals who did not respond to the two-dose MMR vaccine and evaluate the efficacy and durability of immune responses after booster doses. An observational study was conducted involving 24 individuals who were seronegative for measles years after completing the two-dose MMR vaccine schedule.

Depression is common among people living with HCV and HIV, which contributes to health services utilization (HSU). It is unknown whether successful HCV treatment affects this. We examined depressive symptoms and HSU in people co-infected with HIV-HCV and their association with sustained virologic response (SVR) during the direct-acting antiviral era.

Background: Neprilysin (NEP) is a metalloprotease that has become a therapeutic target for the treatment of heart failure and hypertension. However, the significance of NEP in chronic liver diseases has rarely been investigated. In this study, we investigated the serum NEP levels in patients with chronic liver disease and their relationship with clinical parameters.
