Pulmonary cryptosporidiosis in an AIDS patient: successful treatment with paromomycin plus azithromycin.

Extra-intestinal cryptosporidiosis, especially of the biliary and respiratory tract, is likely in the course of an intestinal involvement, whereas it is rare without such a localization. We report a case of pulmonary cryptosporidiosis without apparent intestinal involvement in an AIDS patient, with favourable outcome after antimicrobial combination therapy with paromomycin plus azithromycin. The successful response to antimicrobial treatment was subsequently maintained by effective highly active antiretroviral therapy (HAART). We suggest that respiratory cryptosporidiosis should be investigated in HIV-infected patients with pulmonary symptoms and low CD4 cell count, and, if detected, treatment should include HAART plus the combination of paromomycin and azithromycin.
