An Atypical Case of Plasmodium vivax Malaria after Initiating Adalimumab Therapy

ABSTRACT

We report an unusual case of Plasmodium vivax malaria that occurred in a 22-year-old ankylosing spondylitis patient after initiating adalimumab therapy. P. falciparum malaria was initially included as a possible differential diagnosis due to hyperparasitemia and similar features in the peripheral blood smear. The patient was successfully treated with conventional therapy for P. vivax malaria.
