ABSTRACT

OBJECTIVE:

To determine the drug resistance profile of Mycobacterium tuberculosis in Mozambique.

METHODS:

We analyzed secondary data from the National Tuberculosis Referral Laboratory, in the city of Maputo, Mozambique, and from the Beira Regional Tuberculosis Referral Laboratory, in the city of Beira, Mozambique. The data were based on culture-positive samples submitted to first-line drug susceptibility testing (DST) between January and December of 2011. We attempted to determine whether the frequency of DST positivity was associated with patient type or provenance.

RESULTS:

During the study period, 641 strains were isolated in culture and submitted to DST. We found that 374 (58.3%) were resistant to at least one antituberculosis drug and 280 (43.7%) were resistant to multiple antituberculosis drugs. Of the 280 multidrug-resistant tuberculosis cases, 184 (65.7%) were in previously treated patients, most of whom were from southern Mozambique. Two (0.71%) of the cases of multidrug-resistant tuberculosis were confirmed to be cases of extensively drug-resistant tuberculosis. Multidrug-resistant tuberculosis was most common in males, particularly those in the 21-40 year age bracket.

CONCLUSIONS:

M. tuberculosis resistance to antituberculosis drugs is high in Mozambique, especially in previously treated patients. The frequency of M. tuberculosis strains that were resistant to isoniazid, rifampin, and streptomycin in combination was found to be high, particularly in samples from previously treated patients. .
RESUMO

OBJETIVO:

Avaliar o perfil de resistência de Mycobacterium tuberculosis aos tuberculostáticos em Moçambique.

MÉTODOS:

Foram analisados dados secundários do Laboratório Nacional de Referência da Tuberculose, em Maputo, Moçambique, e do Laboratório Regional de Referência da Tuberculose, na Beira, Moçambique. Os dados foram relativos a amostras positivas à cultura e submetidas ao teste de sensibilidade aos tuberculostáticos de primeira linha durante o período de janeiro a dezembro de 2011. Os resultados do teste de sensibilidade foram analisados, e sua frequência foi comparada com o tipo de paciente e sua proveniência.

RESULTADOS:

Foram analisadas 641 cepas, isoladas em cultura e submetidas ao teste de sensibilidade. Das 641 cepas, 374 (58,3%) foram resistentes a pelo menos um tuberculostático e 280 (43,7%) revelaram-se multirresistentes. Dos 280 casos de tuberculose multirresistente, 184 (65,7%) eram pacientes com tratamento prévio, a maioria dos quais era oriunda da zona sul do país. Confirmou-se que 2 (0,71%) dos casos de tuberculose multirresistente eram casos de tuberculose extensivamente resistente a drogas. O sexo masculino foi o mais afetado, particularmente na faixa etária de 21 a 40 anos.

CONCLUSÕES:

A resistência de M. tuberculosis aos tuberculostáticos é elevada em Moçambique, especialmente em indivíduos com tratamento prévio. A resistência de M. tuberculosis à combinação de isoniazida, rifampicina e estreptomicina foi elevada, especialmente em amostras provenientes de indivíduos com tratamento prévio. .
