Dengue, Platelet indices, MPV, PDW


Background: Dengue is an endemic in tropical and sub-tropical regions of the world and also in various parts of India. Recent evidence indicates that platelet indices can be used to assess the severity and prognosis of dengue. This study aimed to assess the role of the platelet indices-mean platelet volume (MPV), platelet distribution width (PDW), platelet to large cell ratio (P-LCR), plateletcrit (Pct) and hematological parameters like hemoglobin (Hb), hematocrit (Hct) with the platelet count in dengue NS1 antigen positive cases.

Methods: An observational cross-sectional study conducted on cases of dengue over a period of 3 months admitted with serological positivity (NS1 antigen) in a tertiary care hospital, Loni. The platelet indices like MPV, PDW, Pct, P-LCR and hematological parameters like Hb, Hct were noted using Sysmex XN-3100 Automated hematology analyzer and compared with platelet count.

Results: Relationship between various platelet indices like MPV, PDW, P-LCR and PCT and hematological parameters like Hb, TLC and Hct were related with platelet count. Dengue positive cases were inversely related to MPV, PDW, P-LCR, Hb and Hct and directly related to Pct. In the present study Pct, P-LCR, Hb and Hct were statistically significant in correlation with platelet count.

Conclusions: Pct, P-LCR, Hb and Hct along with platelet count can be used to assess the predictive outcomes in case of dengue infection.
