Abstract

Purpose: Detection of human papilloma virus (HPV) infection in clinical practice was examined based on the observation that peripheral blood lymphocytes exposed in vitro to antigenic or mitogenic stimulation change their intracellular structures as measured by polarization of fluorescent light emitted by labeled cells.

Materials and methods: A total of 47 women were enrolled in this study. They were classified into four groups based on the results of HPV-DNA detection in cervical tissues by the Hybrid Capture II kit (Digene, Gaithersburg, MD, USA) and pathological examination. Ten women with no HPV-DNA detection were used as a normal control group. Fifteen women without pathological diagnosis in the cervical tissues had HPV-DNA detection. Ten women with CIN lesions had 80% HPV-DNA detection. Twelve women with invasive squamous cell carcinoma had 100% HPV detection. Peripheral blood lymphocytes derived from all women were collected and then exposed to HPV-E7 antigen and PHA mitogen.

Results: The positive response rate of HPV-E7 antigen was ten percent (1/10) in the normal control group, 73.3% (11/15) in the HPV infectious women, 50% (5/10) in the CIN women, and 91.7% (11/12) in the cervical cancer patients. The overall sensitivity rate of blood tests was 77.1% and the specificity rate was 57.8% when the Hybrid Capture II HPV Test kit was used as the standard detection method for cervical tissue.

Conclusions: The results showed that peripheral blood lymphocytes derived from patients with cervical lesions might be another choice to be used as a screening method to detect HPV infection compared with conventional methods.
