description | INTRODUCTION: The association between Human Papiloma Virus (HPV) positive cervical swabs and the development of cervical cancer has lead to extensive research. Studies employing the RT-PCR method for typization in the young women demographic worldwide. Based on their proven oncogenic potential 14 HPV types have been classified as carcinogenic (HPV16,18,31,33,35,39,45,51,52,56, 58,59,66,68). The imporatnce of HPV diagnostics is a result of the existing link between viral infection and relative risk of cervical cancer, while the detection complexity reflects the large variety of HPV genotypes. METHODS: The samples analyzed in our study were obtained from cervical swabs of women aged 19 to 25 years between the months of October and December 2022. All collected samples were routinely screened for high risk genotype positivity (HPV16 and 18). There were no other inclusion criteria, the samples used in the study were selected at random. After DNA isolation, genotype identification was done by L2 amplification for HPV 16, the L1 for HPV 18, E6 for HPV 35, 56 and 58, and E7 for HPV 31,33,39,45,51,52,59,66 and 68 genotypes, with specific primers and flourescently labelled probes. RESULTS: The results demonstrated that among the DNA positive individuals HPV genotype distribution was as follows: 50% (31,39,56); 40,90% HPV(52,59,68); 34,10% HPV16; 22,70% HPV(35, 58, 66); 15,90% HPV 18. Individually, by type, the highest prevalence was noted for the high risk genotype HPV 16 (34,1%), followed by HPV18 (15,90%). As for group clusters, HPV(31,39,56) were most frequent, followed by HPV(52,59,68). CONCLUSIONS: Given the forementioned results of our study, the most prevalent HPV genotype in the Republic of Serbia among the women of pre-set demographic is HPV 16, which is in conconcurrence with epidemiological results for Eastern Europe. By comparative analysis of the HPV16 and 31 distribution, the results imply a similarity in sensitivity to infection. KEY MESSAGES: • The susceptibility of young adults to HPV infection entails a well-developed preventive medicine program is paramount, and not limited to this demographic. • RT-PCR offers in-depth insight into the distribution of risk of cancer to the screening team. |
