Association of viral kinetics, infection history, NS1 protein with plasma leakage among Indonesian dengue infected patients.

Objectives: Plasma leakage, a hallmark of disease in Dengue virus (DENV) infection, is an important clinical manifestation and is often associated with numerous factors such as viral factors. The aim of this study is to investigate the association of virus serotype, viral load kinetics, history of infection, and NS1 protein with plasma leakage.

Methods: Subjects with fever ≤ 48 hours and positive DENV infection were included.

Circulation of Various Dengue Serotypes in a Community-Based Study in Jakarta, Indonesia.

Dengue virus (DENV) infection remains to be a serious health problem in Indonesia. Community-based dengue studies to determine circulating DENV serotypes based on the geography and season are limited owing to the expensive cost and significant effort required. Many patients with DENV infection are not hospitalized and many visit the hospital in the later phase of the disease.

Anti-Hepatitis C Virus Activity of a Crude Extract from Longan (Dimocarpus longan Lour.) Leaves.

Infection with hepatitis C virus (HCV) results in hepatitis C, a disease characterized by chronic infection, cirrhosis, and hepatocellular carcinoma. Currently, the standard therapy is a combination of pegylated interferon-α plus ribavirin with NS3 protease inhibitors. Addition of NS3 protease inhibitors to the standard therapy improves response rates; however, use of NS3 protease inhibitors is also associated with significant adverse effects and an increase in the overall cost of treatment.

Immunogenicity of a Candidate DNA Vaccine Based on the prM/E Genes of a Dengue Type 2 Virus Cosmopolitan Genotype Strain.

The development of a dengue virus vaccine is a major priority in efforts to control the diseases. Several researchers are currently using the Asian 1 and Asian 2 genotypes as vaccine candidates for dengue type 2 virus (DENV-2). However, in this study, we constructed a recombinant plasmid-based prM/E gene, from a DENV-2 Cosmopolitan genotype strain as a dengue DNA vaccine candidate.
