The aim of this study was to determine human papillomavirus (HPV) types distribution in cervical preneoplasic lesions in a Southern Spanish population and their relationship between HPV type and grade of histopathological abnormality. Finally, 232 cervical samples from 135 women with previous cytological abnormalities were included in this study. Colposcopy studies and biopsies were performed. Haematoxylin-eosin stained slides were observed and detection of HPV DNA in cervical swabs was carried out with use of a polymerase chain reaction and microarrays technology. The relationship between the presence of HPV infection and diagnostic variables was evaluated. HPV 16 was the most common type followed by HPV 58, 51, 33 and 31. However, the two HPV types targeted in the prophylactic vaccines such as HPV type 16 and 18 were detected in only 37 (21.2%) and 2 (1.1%) cases respectively. Thirty-three (18.9%) of samples were infected with multiple types, the majority of them with two types. In addition, during the follow-up of patients many changes in type distribution were observed. Several studies will be necessary in order to evaluate the HPV type distribution for therapeutically and prophylactic purposes such as vaccine treatment. Also, because of the differences obtained depending of use of various DNA technologies, the performance of some comparative studies of the different methods from detection of HPV would be advisable in a high population of patients and with the most homogeneous conditions possible.

Los objetivos propuestos en la investigación han posibilitado identificar y documentar las barreras de acceso y los factores de riesgo en los cuidados de salud en ginecología y obstetricia y evaluar la situación sociofamiliar en la población migrante instrumentando acciones de inclusión en el sistema de salud de la provincia en aquellas pacientes que requirieron una atención de mayor complejidad. La experiencia de trabajo interdisciplinario en una comunidad ha posibilitado estudiar a 99 mujeres en edad fértil, en un 45% de origen boliviano, con alta vulnerabilidad social que habitan en el Distrito Belgrano de Guaymallén. Se realizó un estudio protocolizado, descriptivo y observacional con entrevistas semiestructuradas y control ginecológico, con toma de muestras para Papanicolaou y colposcopía en un consultorio que se instaló en el jardín maternal. Se aplicó un consentimiento informado a todas las mujeres antes de la realización de los estudios. La lectura de las muestras y los estudios específicos incluyeron mamografías y ecografías que se realizaron en los servicios de anatomía patológica y rayos del Hospital Universitario. El equipo del Hospital Universitario que concurrió a terreno estuvo formado por ginecólogos, trabajadores sociales, enfermeros y alumnos de las carreras de grado.
