ABSTRACT
Background: Cervical cancer remains a major public health problem in northern Argentina, showing the highest mortality rate in the country (approximately 22 cases/100000 women). Objective: The aim of this study was to provide epidemiological data on the prevalence and type distribution of human papillomavirus (HPV) in women with pre-neoplastic lesions before the massive introduction of HPV vaccination in the country. Materials and Methods: Exfoliated cervical cells were collected to screen for HPV using the widely known MY09/11 PCR, followed by the restriction fragment-length polymorphism (RFLP) technique from a total of 714 women with previously diagnosed atypical squamous cells of undetermined significance (ASCUS), low-grade squamous intraepithelial lesion (LG-SIL) and high-grade squamous intraepithelial lesion (HG-SIL). Results: Overall HPV prevalence was 48.2% in ASCUS (24 different HPV types detected), 66.5% in LG-SIL (37 HPV types detected) and 82.6% in HG-SIL (16 HPV types detected). HPV-16 was the most prevalent type among all cases. With respect to multiple HPV infections, 9.6% were observed in ASCUS, 14.3% in LG-SIL and 11.4% in HG-SIL. Conclusion: The major strength of our study is the assessment of a large series of women with cytological alterations in this region. The information attained will be useful as a regional baseline for future epidemiological vigilance, in the context of the national HPV vaccination program.

Entre 1975 y 1980 el Gobierno de Venezuela establecio un Centro Nacional de Referencia en Inmunologia Clinica y ocho unidades regionales de inmunologia clinica. Los resultados obtenidos hasta la fecha indican que esta empresa podria servir de modelo para establecer la practica de la inmunologia clinica en otros países en desarrollo
