ABSTRACT
Abstract (1) Background: The Commercial Kit SIRE Nitratase® PlastLabor, is a drug susceptibility test kit used to detect Mycobacterium tuberculosis resistance to first-line TB treatment drugs. The present study aimed at evaluating its performance in a multicenter study. (2) Methods: To determine its accuracy, the proportion methods in Lowenstein Jensen medium or the BACTECTMMGITTM960 system was used as a gold standard. (3) Results: The study revealed that the respective accuracies of the kit with 190 M. tuberculosis clinical isolates, using the proportion methods in Lowenstein Jensen medium or BACTECTMMGITTM960 system as a gold standard, were 93.9% and 94.6%, 96.9% and 94.6%, 98.0% and 97.8%, and 98.0% and 98.9%, for streptomycin, isoniazid, rifampicin, and ethambutol, respectively. (4) Conclusion: Thus, the kit can rapidly screen resistance to streptomycin, isoniazid, rifampicin, and ethambutol. Additionally, it does not require sophisticated equipment; hence, it can be easily used in the laboratories of low and middle income countries.

Objetivos: O presente relato tem como objetivo discutir o diagnostico diferencial entre tuberculose e sarcoidose. Descrição do caso: Caso de um paciente do sexo masculino, 25 anos, que desenvolveu artrite granulomatosa e osteomielite com inflamação granulomatosa não caseosa sugestiva de sarcoidose. Vinte e quatro meses antes desse relato, o paciente teve resultados laboratoriais positivos para tuberculose pulmonar, no entanto, não foi tratado. Conclusão: Demonstramos como é necessário o acompanhamento do paciente após a realização de um teste diagnóstico para tuberculose e o desafio de confirmar um diagnóstico de sarcoidose em um paciente com tuberculose.(AU)
Objectives: The present report aims to discuss the differential diagnosis between tuberculosis and sarcoidosis. Case description: The case of a 25-year-old male patient who developed granulomatous arthritis and osteomyelitis with nonnecrotizing granulomatous inflammation suggesting a sarcoidosis. Twenty-four months before this report, he had positive laboratory results to pulmonary tuberculosis, however, he was not treated. Conclusion: This case report demonstrates how necessary is the follow-up of patient after the performance of a diagnostic testing to tuberculosis, and the challenge to confirm a diagnosis of sarcoidosis in a patient with tuberculosis.(AU)
