Abstract
In the process of progression to cancer from atypical squamous cells of undetermined significance (ASCUS), mostly Human Papilloma Virus (HPV) is responsible. Additionally, patients with cell cycle disorders are thought to be at risk. The aim of this prospective cohort trial was to analyze the association between presence of ASCUS and HPV persistence with folate and vitamin B12 levels. 200 patients who had Papanicolaou (PAP) smear test were divided into a ASCUS group (n:100) and control group (n:100). Control group consisted of women who did not have intraepithelial neoplasia, based on PAP smear results. HPV testing was also done in study group. Serum vitamin B12 and folate levels in ASCUS (+) HPV (+) patients were significantly lower than that of ASCUS (−) or ASCUS (+) HPV (−) patients (p < 0.01). In our study, there was no statistically significant difference between folate levels in patients with different types of HPV (p > 0.05), however vitamin B12 levels of patients with other high-risk HPV types were significantly lower than patients with positive HPV16–18 (p = 0.01). The positivity of HPV in women with ASCUS is associated with low serum vitamin B12 and folate levels.
