Detecção de Aspergillus sp pela técnica de PCR-nested em pacientes submetidos a transplante de medula óssea: [carta ao editor] / Detection of Aspergillus sp in bone marrow transplant patients by PCR-nested technique: [letter to editor]

ABSTRACT

Invasive aspergillosis is an important cause of mortality in long-term neutropenic patients, particularly after bone marrow (B.M.T.) and solid organ transplantation. More than 90% of invasive fungal infections in immunocompromised patients can be attributed to Candida and Aspergillus. To date, there is no fast, reliable and feasible test for Aspergillus infection detection in routine procedures. In the present report, a nested PCR technique, developed to detect Aspergillus infection, is described. In our study, the sensitivity, specificity, positive and negative values using this approach were 100%, 94.4%, 83.3%, and 100%, respectively.
