ABSTRACT

Non-tuberculous mycobacterial adenitis is getting more common in our environment. Epidemiologic studies and clinical trials published nowadays are limited. We present a 2-years-old boy diagnosed of Mycobacterium intracellulare adenitis and severe neutropenia as side effect of combined treatment with oral azythromycin and rifabutin, which recovers after suspending the second one. Liver metabolism of macrolide seems to increase other drugs toxicity, in this case, rifabutin. The patient eventually needed surgery due to persistence of the adenitis despite treatment with antibiotics.


Las adenopatías por micobacterias no tuberculosas (AMNT) son cada vez más frecuentes en nuestro medio. Los estudios epidemiológicos y ensayos clínicos controlados publicados hasta la fecha son escasos. Presentamos el caso de un niño de 2 años con el diagnóstico de una adenitis por Mycobacterium intracellulare que desarrolló una neutropenia grave secundaria a la terapia combinada de azitromicina y rifabutina oral. La metabolización hepática de los macrólidos parece aumentar la toxicidad de otros fármacos, en este caso, la rifabutina. Finalmente, al paciente se le realizó una exéresis quirúrgica por persistencia de la adenitis a pesar de la antibioterapia.
