Study summary

Infection post liver transplantation is an important factor in the death in patients. The traditional method of diagnosing infection post liver transplantation is laboratory tests. But the sensitivity and specificity of blood tests is poor. Next-generation sequencing (NGS) has greater detection rate for mycobacterium tuberculosis, anaerobes and fungi and greater sensitivity compare with blood tests. However use of NGS is limited because of the short read-length. Oxford nanopore adaptive sequencing (NAS) method is the Third Revolution in Sequencing Technology. For each 1 Gbp of data, NAS sequencing detected 45 times more microbiome sequences than Nanopore standard sequencing and 2.5 times more than Illumina sequencing. The purpose of this study is to compare NAS with NGS and laboratory tests for the diagnostic rate of infection post liver transplantation.

Read the detailed description

Based on the previous work, the investigators found that: 1. NAS has a higher microbial enrichment efficiency and can detect pathogenic information more quickly compared with nanopores normal sequencing (NNS); 2. NAS can detect more specific pathogen fragments with short-time sequencing; 3. NAS can cover more pathogenic genomes than NNS in a short-time; 4. NAS can detect antibiotic resistance information of pathogenic bacteria in clinical samples.

Study population

Participants will be recruited randomly and if they violate the protocol or occur clinical adverse events, the investigators will ask them to withdraw from this study.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Accept liver transplantation
  • Signing voluntarily
  • Possessing ability to comprehend material information
  • Participating this study voluntarily

Exclusion criteria

Exclusion Criteria:

  • Participated another study
  • Graft loss
  • Have undergone a multi-organ transplantion or have had a previous organ transplantation
  • Patient died
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
