Kinetics of CD4 T Helper and CD8 Effector T Cell Responses in Acute Dengue Patients.

The protective or pathogenic role of T lymphocytes during the acute phase of dengue virus (DENV) infection has not been fully understood despite its importance in immunity and vaccine development. This study aimed to clarify the kinetics of T lymphocyte subsets during the clinical course of acute dengue patients. In this hospital-based cohort study, 59 eligible Vietnamese dengue patients were recruited and admitted.

Plasma cell-free DNA: a potential biomarker for early prediction of severe dengue.

Background: Considerable progress has been made in dengue management, however the lack of appropriate predictors of severity has led to huge number of unwanted admissions mostly decided on the grounds of warning signs. Apoptosis related mediators, among others, are known to correlate with severe dengue (SD) although no predictive validity is established. The objective of this study was to investigate the association of plasma cell-free DNA (cfDNA) with SD, and evaluate its prognostic value in SD prediction at acute phase.

Association between dengue severity and plasma levels of dengue-specific IgE and chymase.

There is no definitive predictor of dengue severity, and this has led to a very large number of unnecessary hospitalizations worldwide. Although mast cell mediators are believed to a play role in dengue severity, the lack of precise kinetic data demands further research on early predictors. We enrolled 111 patients with confirmed dengue and 85 with "other febrile illness" (OFI) in a hospital-based prospective study in Vietnam.
