Summary of cardiovascular function study Lassa fever carries a treated mortality in hospitalized patients of up to 30%. Lassa fever is often described as being characterized by vascular leak and shock in the terminal phase, but, whilst animal data supports this, there are limited data in humans. A further aim of this study therefore is to characterize cardiovascular function in patients with Lassa fever, with the ultimate goal of informing future trials of supportive or therapeutic strategies. Summary of ribavirin pharmacokinetics and pharmacodynamics sub-study Lassa fever carries a treated mortality in hospitalized patients of up to 30% in Nigeria. Ribavirin is the current standard of care. However, the efficacy of ribavirin has not been established in RCTs. There is very limited PK data on ribavirin in patients with Lassa fever and the optimal dose of ribavirin for an RCT is unknown. The aim of this study is to characterize the PK of ribavirin in Lassa fever, and identify any associations between ribavirin PK parameters and viral load and markers of inflammatory status.
