Abstract:
We determined CYP2D6*4 and CYP2D6* genotypes and metabolizer phenotypes in 96 patients with suspected malaria in Venezuela and found intermediate or poor metabolizer phenotypes in ≈25% of cases. Nine of 44 malaria patients had Plasmodium vivax recurrence. Public health authorities should evaluate the benefits of increasing total doses of primaquine for treatment.
