Blastocystosis: nitazoxanide as a new therapeutic option

Abstract

We report a case of a patient with AIDS and severe immunosuppression who developed diarrhea due to a vacuolar stage of Blastocystis hominis. The patient was treated with nitazoxanide, a 5-nitrothiazole broad-spectrum antiparasitic agent. We obtained complete remission of symptoms and eradication of the parasite. Nitazoxanide is a new treatment option for blastocystosis in AIDS patients. Further studies to test its efficacy are needed.
