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.
To investigate any association between echinocytosis and dengue infection.
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.
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 (
Echinocytosis may be associated with severe disease.
