Detecção de Treponema pallidum em amostras de sangue fixadas em cartão para diagnóstico da sífilis congênita

Abstract: A sífilis congênita (SC) é uma doença de transmissão vertical causada pelo Treponema pallidum provocando uma infecção do bebê ainda no útero. O diagnóstico da SC é difícil e tem sido feito por uma combinação de critérios clínicos e laboratoriais, o que torna necessário a busca por novos métodos de diagnóstico para auxiliar a tomada de decisão. Os testes moleculares, apesar de ainda não serem rotina nos laboratórios, estão sendo cada vez mais utilizados. A etapa pré-analítica de coleta da amostra, extração e pr… Show more

“…These results indicate that, although molecular tests are not routinely used in laboratories, when applied to detect Treponema in CFS samples, as long as they are improved, they can enable the diagnosis of congenital syphilis (CS) and facilitate neonatal screening in Brazil. The availability of a PCR test to identify Treponema pallidum directly in blood samples from newborns represents a valuable contribution in addressing this diagnostic challenge (24,25) .…”
