Echinocytes in the peripheral blood of patients infected with dengue virus may be a predictor of disease severity

Background

Echinocytes have been demonstrated as sequelae to serum high-density lipoprotein decreases in patients with liver disease, but not to our knowledge in dengue virus infection.

Objective

To investigate any association between echinocytosis and dengue infection.

Methods

We retrospectively studied a cross-section of patients at Mahasarakham University Hospital infected with dengue in August 2015. Infection was diagnosed clinically, and by rapid immunochromatography when nonstructural protein 1 antigen, or IgM or IgG antibodies were detected in the serum. We used World Health Organization 2009 and 2011 criteria to define dengue severity. We examined peripheral blood smears made before and after defervescence.

Result

Two patients had warning signs, 6 did not, 1 had dengue hemorrhagic fever (DHF), and 7 had uncomplicated dengue fever (DF). The ages of patients with and without warning signs was not significantly different (P > 0.99). Patients with warning signs had a mean (SD) alanine transaminase (ALT) level of 354.50 (291.91) IU/L, while the level was 29.67 (20.61) IU/L in those without. The lowest mean platelet count in the patients with warning signs was 35.5 (21.9) × 103 cells/mm3, while the count was 98 (66.1) × 103 cells/mm3 in those without. There was no significant difference in mean ALT level (P = 0.28) or the platelet count (P = 0.09) between patients with and without warning signs. Echinocytes were significantly associated with DWS (P = 0.04), but did not differ significantly between the DHF and DF patients (P = 0.13).

Conclusion

Echinocytosis may be associated with severe disease.
