Visceral leishmaniasis and other severe infections in an adult patient with p47-phox-deficient chronic granulomatous disease.
We report a rare case of a male patient without known immunodeficiency consecutively diagnosed with visceral leishmaniasis, brain abscess and cavitating pneumonia in the 3rd decade of life. Chronic granulomatous disease (CGD) was diagnosed by a nitroblue tetrazolium test. A p47-phox mutation of the NADPH oxidase of the leukocytes was suspected by immunoblotting and confirmed by DNA analysis. The patient was homozygous for this mutation while his mother and sister were heterozygous asymptomatic carriers. After the CGD diagnosis the patient started a chronic prophylactic regimen with subcutaneous interferon-gamma (0.05 mg/m2 of body surface/three times a week), and oral trimethoprim-sulfamethoxazole and itraconazole (both at 5 mg/kg/day) with no subsequent infections after 12 months of follow-up.
