Avaliação crítica do uso da reação em cadeia da polimerase e exames complementares no diagnóstico da tuberculose cutânea e micobacteriose atípica / The role of polymerase chain reaction and panel exams in the diagnosis of cutaneous tuberculosis and atypical mycobacteria skin infection compared to clinical evaluation

RESUMO

Realizou-se estudo comparando o uso da reação em cadeia da polimerase à evolução clínica e painel de exames tradicionais para diagnóstico em pacientes com suspeita clínica de tuberculose cutânea e micobacteriose atípica. Observou-se sensibilidade da reação em cadeia da polimerase de 88 por cento, especificidade de 83 por cento, valor preditivo positivo de 82 por cento, valor preditivo negativo de 88 por cento e acurácia de 85 por cento com concordância pelo teste de McNemar (p= 0,655). Os exames do painel de maior acurácia / A study was performed comparing the polymerase chain reaction and the traditional panel of exams for the diagnosis in patients with a clinical suspicion of cutaneous tuberculosis and atypical mycobacteria infection to the clinical evaluation. It was observed that the sensitivity of the PCR was 88 per cent, the specificity was 83 per cent, the positive predictive value was 82 per cent, the negative predictive value was 88 per cent and the accuracy was 85 per cent in agreement with the McNemar test (p=0.655). The panel exams of second highest accuracy...
