简要总结
It is an experimental study, multicentre, non-profit, whose aim is to preliminarily evaluate the sensitivity of ddPCR for the detection of cfDNA in the diagnosis of cystic echinococcosis and to generate data for its potential use also for the discrimination of the presence of infection with active/inactive cysts and the post-therapy follow-up.
详细描述
It is an experimental study, multicentre, non-profit, whose aim is to preliminarily evaluate the sensitivity of ddPCR for the detection of cfDNA in the diagnosis of cystic echinococcosis and to generate data for its potential also use for discrimination of the presence of infection with active/inactive cysts and follow-up aftercare, to be explored in subsequent studies. For this purpose, the plasma of adult patients with untreated hepatic cystic echinococcosis will be analysed.
The analyzes will be carried out on samples of patients who have already had a definitive diagnosis of cystic echinococcosis, and therefore the results of the study analyzes will have no influence on the diagnosis and clinical management of the patient, which, therefore, will not be informed of the result of the analyzes relating to his/her sample.
