Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older with confirmed moderate to severe Lassa fever and significant health impairment.

Probably not a fit

Patients who are pregnant, lactating, or have contraindications to ribavirin or dexamethasone will not benefit from this study.

What this trial studies

This clinical trial evaluates the safety and tolerability of dexamethasone as an adjunct treatment for moderate to severe Lassa fever, alongside standard antiviral therapy with ribavirin. The study is a prospective open-label randomized controlled trial conducted at the Irrua Specialist Teaching Hospital in Nigeria, where dexamethasone has shown promise in managing co-infections. Participants will be randomly assigned to receive either ribavirin alone or ribavirin plus dexamethasone to assess the potential benefits of the corticosteroid in reducing immune-mediated damage associated with the disease.

Why it matters

Potential benefit: If successful, this treatment could significantly improve outcomes for patients suffering from severe Lassa fever.

How similar studies have gone: While the use of dexamethasone in other infectious diseases has shown success, this specific application for Lassa fever is novel and untested.
