Objectives:To reveal laboratory factors that distinguish dengue fever from other common viral
infections such as Epstein-Barr virus (EBV), cytomegalovirus (CMV), and human immunodeficiency virus (HIV) in a Japanese General Internal Medicine walk-in clinic.
Design:Retrospective cross-sectional survey
Setting:A university hospital in Japan
Participants:Ten Japanese patients with dengue fever (diagnosed from August 2000 to
October 2014) were compared with the most recent 10 patients diagnosed with CMV, EBV, or
acute HIV infections (retroactively extracted back to October 31, 2014).
Main Measures:Epidemiological data, clinical information, and laboratory findings were
extracted from the medical charts of the patients and laboratory findings were analyzed using
Kruskal-Wallis with post-hoc Tukey analysis, where appropriate.
Main Results:The clinical manifestations of dengue fever, fever of 37℃ or more (100%), skin
eruption (80%), headache (70%), arthralgia (60%), and petechiae (50%) were frequently found
in dengue fever. The laboratory findings of dengue fever showed leukocytopenia of 3,500/mm3 or
less (80%) and thrombocytopenia of 100,000/mm 3 or less (70%). The comparisons of laboratory
findings for acute-phase dengue virus infection and infection with other viruses revealed that the
factors that most distinguished risk for dengue fever from other infectious diseases were
leukocytopenia (p<0.01) and thrombocytopenia (p<0.01).
Conclusion:Leukocytopenia and thrombocytopenia exhibited highly significant associations
with infection by dengue virus compared with infection by other viruses, which suggests the
discriminative usefulness of common laboratory examinations.
