Abstract

Although tafenoquine was highly effective for eliminating microscopically detectable parasitemia in mouse models of infection, all of the mice which were assessed developed a relapse of infection, except for those which had been treated concomitantly with artesunate. We report an immunocompromised patient with a similar relapse of parasitemia despite a 46-day course of tafenoquine treatment. More data on whether a longer duration of tafenoquine treatment or using a higher maintenance dose, versus adding a second drug to the regimen, will prevent relapse when tafenoquine is used to treat a highly immunocompromised patient with babesiosis should be investigated.
