Dengue Infection in a Human Immunodeficiency Virus-1 Positive Patient Chronically Infected with Hepatitis B Virus in Western Mexico.

Human immunodeficiency virus (HIV) and dengue coinfection has not been extensively studied. We report herein a case of dengue serotype 1 infection in an HIV-1-positive patient coinfected with hepatitis B virus (HBV) in Colima State, Mexico. CD4+ cells and HIV-1 viremia remained at normal levels, and no severe complications were observed during this multiple viral infection. The alanine transaminase and aspartate transaminase values were elevated before and during dengue infection. Surprisingly, these parameters were significantly reduced 2 months later. Because of the lack of evidence regarding this multiple viral interaction, further research is required to understand the biologic and clinical course of dengue infection in HIV-1/HBV coinfected patients, especially in tropical regions where dengue virus transmission is highly active. © The American Society of Tropical Medicine and Hygiene.
