Abstract

We evaluated the outcome of 71 Japanese patients with chronic hepatitis C who exhibited a sustained normal level of serum ALT for one to five years after the cessation of interferon (IFN) therapy. Patients were classified into two groups: 9 (13%) cases with a sustained positive for serum HCV-RNA (incomplete responders: ICR) and 62 (87%) cases with a sustained negative for serum HCV-RNA (complete responders: CR). The anti-C100-3 titer was similarly decreased in both groups especially up to one year after cessation of IFN becoming negative in 50% of each group over a 4-year period. The anti-C-22 titer was also decreased in the CR group and stabilized at about 100U (RIA). The titer of anti-C-22 was either increased or maintained at pretreatment levels in most cases of ICR. Monitoring of anti-C-22 may be useful in distinguishing the presence of HCV viremia from a previous HCV infection. According to the backgrounds between both groups, ICR cases were significantly older and more often of genotype 1b (67%) than CR cases (1b; 32%), however there were no significant differences in sex, liver histology or pretreatment levels of HCV-RNA. Serum levels of HCV-RNA in ICR cases after IFN therapy either increase or remained similar to pretre...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
