Impact of the GeneXpert® MTB/RIF rapid molecular test on tuberculosis detection: temporal trends and vulnerable territories

Abstract: Objective: to assess the impact of the GeneXpert® MTB/RIF rapid molecular test on tuberculosis detection, to analyze the temporal trend of the event and to identify vulnerable territories in a Brazilian municipality. Method: an ecological study carried out in Ribeirão Preto, São Paulo, Brazil, a municipality considered a priority in tuberculosis control due to the high number of cases. To classify the temporal trend, the Prais-Winsten method and the Interrupted Time Series were used to identify changes in the… Show more

“…As a result, the previous drug sensitivity test (DST) took a relatively long time to perform and was not effective in providing clinicians with timely and scientifically sound results for diagnosing patients' diseases. As molecular biology diagnostic technologies are adopted in clinical tests, more advanced detection methods are widely applied in the laboratory detection of TB, among which the real-time fluorescence quantitative nucleic acid amplification detection of MTB/RIF resistance (GeneXpert MTB/ RIF) and gene chip technology are frequently used at this stage [4]. rough a search of the current published literature, the lesser literature compares the diagnostic efficacy of the GeneXpert MTB/RIF (real-time quantitative fluorescent nucleic acid amplification assay), the gene chip technique, and the modified Roche culture method for sputum sent for testing, respectively.…”

“…Ela obedece a todos os critérios de priorização de um agravo em saúde pública, ou seja, de grande magnitude, transcendência e vulnerabilidade (BRASIL, 2011a;CECILIO et al, 2013) (SALES et al, 2010). Uma outra problemática ainda é o número elevado de crianças menores de um ano com mortes, por pneumonia por causa inespecífica (BERRA et al, 2021), o que levanta a hipótese de subnotificação da TB (CANO et al, 2017).…”

“…et al, 2015; Mendes M.D.S. et al, 2021), entretanto, todos estudos identificados no Mapeamento Sistemático da Literatura objetivaram identificar e estimar o risco de determinada área.de controle e, também, diminuir custos operacionais(BERRA et al, 2021) Em relação a questão secundária 3 a TB é um dos agravos de saúde influenciado por determinantes sociais e demonstra relação direta com a pobreza e a ano considerado, a ocorrência de casos indica a persistência de fatores favoráveis à propagação do bacilo Mycobacterium tuberculosis(SOUZA et al, 2018) Berra et al (2021). aponta em seu estudo sobre as implicâncias do uso do teste para o diagnóstico da TB infantil e sugere a realização de estudos futuros após decorrido mais tempo de uso dessa nova tecnologia diagnóstica, para averiguar a possível relação da queda da incidência de tuberculose em menores de 15 anos e a maior sensibilidade do TRM-TB, realizado pelo sistema GeneXpert® MTB/RIF, como resultados de seu estudo em Ribeirão Preto -SP e que essa identificação deve ser olhada com cautela, pois, ao contrário de indicar que as políticas e estratégias para o combate à tuberculose estão obtendo êxito, podem indicar que novos casos não estão sendo diagnosticados e/ou notificados.…”
