Randomized Controlled Trial Multicenter Study Clinical Trial
A randomized, double-blind, placebo-controlled trial evaluating the safety of early oseltamivir treatment among children 0-9 years of age hospitalized with influenza in El Salvador and Panama.
Oseltamivir reduces symptom duration among children with uncomplicated influenza, but few data exist on treatment efficacy and tolerability among hospitalized children, particularly among infants aged <1 year. We evaluated tolerability and efficacy of oseltamivir treatment of children aged 0-9 years hospitalized with influenza. ⋯ Oseltamivir treatment was well tolerated among hospitalized children, including among infants aged <1 year.

Highly pathogenic human coronaviruses associated with a severe respiratory syndrome, including Middle East respiratory syndrome coronavirus (MERS-CoV), have recently emerged. The MERS-CoV epidemic started in 2012 and is still ongoing, with a mortality rate of approximately 35%. No vaccine is available against MERS-CoV and therapeutic options for MERS-CoV infections are limited to palliative and supportive care. ⋯ Spike proteins have a dual function during entry, they mediate binding to the host cell surface and also the fusion of the viral envelope with host cell membrane. Time course experiments show that griffithsin inhibits MERS-CoV infection at the binding step. In conclusion, we identify griffithsin as a potent inhibitor of MERS-CoV infection at the entry step.
