Surveillance of human papilloma virus infection and cervical cancer in kidney transplant recipients: preliminary data.
BACKGROUND
Development of cancer after transplantation has rapidly became one of the leading causes of death in kidney transplant recipients with functioning grafts. Anogenital malignant neoplasms may occur with a 14-fold increased incidence, and human papilloma virus (HPV) infection has been recently identified as the leading cause of cervical carcinoma. We report the preliminary findings of a prospective study that evaluated the incidence of HPV infection and cervical carcinoma in a population of kidney transplant recipients.


METHODS
The study included 35 female recipients of a deceased donor kidney with at least 6 months of follow-up. All patients underwent a cervicovaginal brushing, an HPV DNA test, and a Papanicolaou test.


RESULTS
Twenty-two patients (62.8%) were positive for HPV DNA. Thirteen of 22 HPV DNA-positive recipients (59%) demonstrated a high-risk HPV genotype. No cytologic anomalies were detected in Papanicolaou smears.


CONCLUSIONS
These preliminary data demonstrated a high incidence of HPV infection in renal transplant recipients. Most of our recipients exhibited a high-risk HPV genotype, which suggests higher aggressiveness of such infection in immunosuppressed patients. The HPV test is useful to monitor patients at higher risk of anogenital malignant neoplasms by identifying the cytologic anomalies at an earlier stage. This ongoing study will investigate the rate of progression of HPV infection and the clinical patterns of HPV-positive cytologic anomalies in renal transplant recipients.
