ABSTRACT
Mycobacterium tuberculosis, primariamente resistente a múltiplas drogas, é problema de crescente importância nos Estados Unidos. No Brasil, näo existem relatos, pelo menos em literatura formal, de infecçäo por este patógeno. Relato de caso. Os autores relatam caso de paciente do sexo masculino que teve diagnóstico de tuberculose ganglionar cervical por meio de baciloscopia. Adicionalmente, anti-HIV feito por método ELISA resultou positivo. O paciente iniciou esquema terapêutico com isoniazida, rifampicina e pirazinamida. Segundo o paciente e seus familiares, os medicamentos foram administrados corretamente, mas näo foi observada melhora clínica. Após 75 dias de tratamento, o paciente foi internado no Hospital do Servidor Público Estadual de Säo Paulo com piora clínica caracterizada por aumento de gânglio submandibular, insuficiência respiratória e dor abdominal, vindo a falecer seis dias após a admissäo. Cultura do aspirado ganglionar, colhida no dia da internaçäo, mostrou crescimento de M. tuberculosis sensível ao etambutol e resistente à isoniazida, rifampicina, pirazinamida, etionamida e estreptomicina. Discussäo. O isolamento de M. tuberculosis multirresistente, mesmo que em paciente com forma extra-pulmonar da doença, traz à tona discussäo da necessidade da prevalência do patógeno em nosso meio mediante realizaçäo de cultura e antibiograma, e ressalta problemas inerentes à MTB-MDR, como a alta letalidade em pacientes com infecçäo clinicamente manifesta e a transmissäo intra-hospitalar, já demonstrada em outros países. É discutida a necessidade de cumprimento rigoroso das medidas de isolamento

Primary multidrug-resistant Mycobacterium tuberculosis is an important problem in the United States. There is no report in formal literature of this pathogen in Brazilian patients. CASE REPORT--We report a case of ganglionar tuberculosis diagnosed by acid-fast smears in a male, HIV positive patient. Mode of acquisition of HIV was not determined. Treatment was started, and isoniazid, rifampicin and pyrazinamide were prescribed. The patient and his family reported strict adherence to therapy, but no improvement was observed. After 75 days, the patient was admitted in our hospital because of clinical worsening. Clinical features were the presence of large submandibular and axillar lymph nodes, respiratory insufficiency and complains of abdominal pain. He died six days after admission. Culture obtained from the ganglionar aspirate disclosed M. tuberculosis susceptible to ethambutol, but resistant to isoniazid, rifampicin, pyrazinamide, ethionamide and streptomycin. DISCUSSION--Although this was a case of extrapulmonary tuberculosis, there is a concern about multidrug-resistant tuberculosis, that has been poorly evaluated in Brazil. Since high lethality and intrahospital transmission have been reported, we discuss the need of performing culture and antibiogram in suspected cases, and the prevention of the spread of M. tuberculosis to patients and health-care workers through the strict adherence to the isolation practices.
