| Abstract |
The immune pathogenesis of dengue involves antibody production, B cell and T cell response and various pro-inflammatory and anti-inflammatory cytokines. VEGF, a potent permeability enhancing cytokine, is thought to play a pivotal role in mediating plasma leakage in DHF. It is a member of growing family of related proteins that includes VEGF B, VEGF C, VEGF D and placental growth factor. It promotes angiogenesis and vascular integrity. In addition to its role in promoting endothelial permeability & proliferation, it may contribute to inflammation and coagulation. This study was undertaken to investigate the role of VEGF in the patients with dengue infection. Sera were collected from 106 patients with various grades of dengue illness and 40 healthy controls and tested for VEGF levels using commercial ELISA kits. Viral serotypes were detected using specific primers. The results showed very low levels of VEGF (3.493 ± 1.982 pg/ml) in healthy controls. Levels of VEGF were higher in patients with severe dengue (428.170 ± 224.61 pg/ml) as compared to patients with non severe dengue with and without warning signs (290.407 ± 167.17 pg/ml). Significant correlation (p < 0.001) was found between raised VEGF levels and thrombocytopenia and raised haematocrit levels. The VEGF profile patterns discovered between the different phases of illness indicate an essential role in dengue pathogenesis and with further studies may serve as predictive markers for progression of dengue fever to severe dengue infection. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 01 March 2016.
All research outputs
#20,311,744
of 22,852,911 outputs
Outputs from VirusDisease
#210
of 322 outputs
Outputs of similar age
#333,953
of 397,141 outputs
Outputs of similar age from VirusDisease
#7
of 13 outputs
Altmetric has tracked 22,852,911 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 322 research outputs from this source. They receive a mean Attention Score of 4.1. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 397,141 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 13 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
