Monkeys infected intravenously with a lethal dose of LCMV-WE provide a model for Lassa fever virus infection of man. Like Lassa fever in man, disease begins with flu-like symptoms and progresses rapidly to death within two weeks of infection. It is essential to correctly diagnose hemorrhagic fever rather than more benign viral diseases to provide the proper treatment. Microarray analyses were conducted on blood of macaques infected with virulent WE virus, and compared to gene expression in monkeys infected with non-virulent LCMV-ARM. We observed gene expression changes that occur before the viremic stage of the disease, and could potentially serve as biomarkers that discriminate between exposure to a hemorrhagic fever virus and exposure to a benign virus. In particular, transcription analysis revealed an early and severe suppression of the COX2 pathways indicating that disease treatments should avoid COX-inhibitors, like aspirin, and favor pathway stimulators.
