Transplant recipients and Anal Neoplasia (TAN) study dataset

The University of Sydney

Dataset description

This dataset includes up to 125 kidney transplant recipients recruited from Westmead Hospital, New South Wales, Australia. Baseline data includes demographics, risk factors of HPV-associated anal squamous cell cancer, cigarette smoking, sexual behaviours, history of anogenital warts and previous abnormal cervical cytology, concurrent but unrelated anal conditions and sexual practices. Clinical data such as date of transplantation, time on waiting list and current immunosuppression treatment were obtained from patients' clinical records. Anal swab test results for HPV detection and genotyping and cytopathology were collected.

Brief Summary

The primary purpose of this trial is to evaluate the feasibility of providing screening for human papilloma virus (HPV) infection of the anus in patients who have had or who are on the waiting list for a kidney transplant at Westmead Hospital. The trial also aims to provide initial estimates of the prevalence of HPV infection in this population. Who is it for? You may be eligible to enroll in this trial if you are aged over 18 years, and you have had or are on the waiting list for a kidney trans ....

Intervention code Early detection / Screening

Brief name: anal swab Kidney transplant recipients attending routine review appointments will be approached to participate. They will be provided a participant information and consent form (PICF) detailing the purpose, methods and risks and benefits of the study. The study will include adults willing and able to give informed consent in English. Consented participants will complete an initial coded demographic and behavioural questionnaire. Trained staff will then take an anal swab taken using a ....

Outcome: Prevalence of type-specific anal human papilloma virus (HPV) infection in renal transplant recipients, using PCR amplification of target DNA, and hybridization with a reverse line blot system.
Timepoint: Anal swab will be performed within 14 days after completion of baseline questionnaire. Genotyping will be performed in batches, for every 20 participant samples.

Outcome: Prevalence and type of anal cytological abnormalities in renal transplant recipients, using ThinPrep (Hologic) standard procedure.
Timepoint: Anal swab will be performed within 14 days after completion of baseline questionnaire. Cytology testing will be performed within 7 days of sample collection.

Outcome: Feasibility of use of anal swabs as a screening tool for the detection of HPV infection and abnormal cytological abnormalities. This will be assessed through enrolment rates from all eligible approached participants and also feedback given in the baseline questionnaires.
Timepoint: Feasibility will be assessed after all participants have been tested, and followed up if needed.
