Genital HPV Infections Before and After Renal Transplantation

October 24, 2016 updated by: Joanne A. de Hullu, MD, PhD, University Medical Center Nijmegen

The Incidence, Prevalence and Genotype of Genital Human Papillomavirus Infections in Females Before and After Renal Transplantation

The purpose of this study is to examine the prevalence, incidence and genotype of anogenital HPV infections in women before and after renal transplantation. With this information the investigators can determine the value of vaccination in patients waiting for renal transplantation in the future.

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Each year about 800 renal transplantations are performed in the Netherlands. The current immunosuppressive strategies have led to a 1-year patient and graft survival of more than 90%. This high survival rate urges medical specialists to pay increasing attention to the long-term side effects of immunosuppressive medication, such as virus-associated cancers. An example of an oncogenic virus is the high risk Human Papillomavirus (hrHPV) which is related to (pre)malignancies of the anogenital tract e.g. cervix, vulva and anus. These malignancies are among the most common malignancies in renal transplant recipients (RTRs). The incidence of hrHPV-related cervical and vulvar malignancies is increased up to a 100-fold in RTRs compared to the general population. There is limited literature on the exact behaviour of HPV infection related anogenital (pre)malignancies in RTRs. A part of these (pre)malignancies are probably already present at the time of transplantation while others develop in the years after transplantation. With gynaecological examination the investigators can diagnose anogenital (pre)malignancies before transplantation so treatment, if necessary, can commence before transplantation. Knowledge about HPV status before and after transplantation gives insight in the natural course of the HPV infection in this group of patients and with this information the investigators can determine the value of vaccination in patients waiting for renal transplantation in the future.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

The study population consists of women above 18 years of age with end stage renal disease who are registered for renal transplantation

Inclusion Criteria:

  • Female sex;
  • Age ≥ 18 years at start of the study;
  • Eligible for renal transplantation;
  • Operation at the Radboud University Nijmegen Medical Centre;
  • Signed informed consent;

Women, renal disease, transplantation
Women with end-stage renal disease, whose eligibility for renal transplantation is assessed

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Prevalence of genital HPV infection before and after renal transplantation in women with end stage renal disease
Time Frame: 6 months before and 6 months after renal transplantation
The difference between post-transplantation prevalence (two HPV tests in 6 months after transplantation)and pre-transplantation prevalence (two HPV tests in 6 months before transplantation) will be compared.
6 months before and 6 months after renal transplantation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Incidence of genital HPV infection before and after renal transplantation
Time Frame: Assessed every 3 months for 2 years
Assessed every 3 months for 2 years
Genotype of the HPV infection per time point
Time Frame: Assessed every 3 months for 2 years
Assessed every 3 months for 2 years

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
February 1, 2012

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
