Mycobacterium bovis dissemination (BCG strain) among immunodeficient Brazilian infants.
This study reports Mycobacterium bovis (BCG strain) dissemination in four primary immunodeficient (PID) patients. Their diagnoses were: chemotaxis defect, cellular immunodeficiency, combined immunodeficiency and chronic granulomatous disease (CGD). Patients were vaccinated with BCG (Moreau strain) between 17 days and 4 months of age. Identification of the BCG strain was performed in many sites, such as bone marrow, ganglionic mass, cerebrospinal fluid and in the site of vaccination. The first therapeutic schedule included rifampicin, isoniazid and ethambutol; no uniform treatment could be used for these patients. Therapy was adjusted as required on the basis of BCG sensitivity results. This study shows that PID patients are susceptible to BCG dissemination and demonstrates the importance of an early diagnosis for their prognosis.
