HPV 16 and 18 are known to be the main cause of cervical intraepithelial neoplasia (CIN) and cervical cancer. The terms of HPV persistence in the host and, coordinately, the risk of cervical neoplasia development and progression are determined in much extent by virus activity. The purpose of this investigation was the detection of HPV DNA presence in cervical epithelium as well as confirmation of its activity by means of immunocytochemistry and reverse transcriptase polymerase chain reaction. The level of HPV inf ection by oncogenic and nononcogenic types in 181 women with different cervical pathology was 55,8%. The active stage of HPV infection was confirmed in 27,5% of HPV-inf ected women mainly with low grades of CIN. The proof of reproductive general HPV infection was more informative with RT PCR just as for HPV 16 and 18 immunocytochemistry and RT PCR completed each anothe.

Background and objectives: Cervical cancer due to Human papillomavirus (HPV) is one of the leading causes of morbidity and mortality in women. Testing of HPV can identify women who are at risk of cervical cancer. Nowadays, molecular methods like real time polymerase chain reaction (PCR) and hybrid capture technique are applied for detecting HPV in cervical specimens. The objective of the present study was to determine the rate of HPV infection in women with chronic cervicitis and cervical intraepithelial neoplasia (CIN) by a commercial real time polymerase chain reaction test kit and by a hybrid capture HPV DNA test.Methods: Women aged between 20 to 55 years with chronic cervicitis and CIN were enrolled in the study after obtaining informed consent. Cervical specimen was collected by using cervical brush and stored in transport medium until used. HPV was detected by High Risk Screen Real-TM Quant 2x (Sacace, Biotechnologies SrI, Italy) real time PCR kit (HR RT-PCR) and by Hybrid Capture-2 High-Risk HPV DNA (Hc-2; Digene Corporation, USA) test.Results: Total 72 women with chronic cervicitis and CIN of different grades were included in the study. Out of this, HPV infection detected by HR RT-PCR was 31 (43%) and by Hc-2 was 14 (19.4%). Both the tests were able to detect HPV infection in all the CIN 3 cases and in most of the CIN 2 cases. However, HR RT-PCR detected higher number of HPV in chronic cervicitis and CIN1 cases.Conclusion: The study has shown that HR RT-PCR and Hc-2 tests are equally effective in detecting HPV infection in patients with CIN 2 and CIN 3 lesions. However, HR RT-PCR is more sensitive test for detecting HPV in chronic cervicitis and early CIN lesions and, therefore can be used in epidemiological study to detect presence of HPV in general population.IMC J Med Sci 2016; 10(2): 45-48

Objective Human papillomavirus (HPV) has been identified as the principal etiologic agent for cervical cancer and its precursors. Different HPV types have been associated with different oncogenic potential. The purpose of this study was to evaluate the relationship between specific HPV type infection and expression pattern of the ras family oncogenes in different grades of HPV-associated human cervical neoplasia. Methods HPV typing was performed using polymerase chain reaction (PCR) in 31 HPV-positive human cervical specimens from patients with squamous intraepithelial lesions (SIL) or squamous cervical carcinoma (SCC). The mRNA expression levels of H-, K- and N-ras oncogenes were examined using the reverse transcriptase polymerase chain reaction (RT-PCR) technique. Statistical analyses were performed using SPSS software. Results Among patients with SCC, H-, K- and N-ras expression levels were higher in HPV 16/18-associated cases compared to HPV 16/18-unassociated samples (p=0.003, p=0.004 and p=0.0001, respectively). The expression levels for H-, K-and N-ras were significantly higher in SCC patients with multiple HPV infection compared with SCC patients with single HPV infection (p=0.009, p=0.01 and p=0.021, respectively). Among patients with SIL, no statistically significant relationship was found between ras expression and HPV status. Conclusion Our findings indicate the possible role of ras signaling interaction with “high-risk” HPV 16/18 and multiple HPV infection in cervical cancer development.

The aim of this study was to evaluate the accuracy of human papillomavirus (HPV) genotyping by a polymerase chain reaction (PCR)-based genechip method and to determine the prognostic value of HPV genotype in bulky stage IB or IIA cervical carcinoma treated with neoadjuvant chemotherapy (NAC) and radical surgery. A total of 149 patients had adequate tissue for the study. The SPF1/GP6+ primers were used to amplify a 184 bp fragment. The amplimers were submitted for direct sequencing and hybridization with a genechip using revert-blot detection of 39 types of HPV DNA in a single reaction. Two runs of PCR with respective hybridization were performed for each tumor. The complete concordance of HPV genotyping was 80.5% (120/149) of the paired genechip results. The kappa coefficient was 0.634 (P < 0.0001). HPV DNA sequences were detected in 100% of the specimens, among which 67.8% harbored single type and 32.2% contained multiple types. HPV-16 was detected in 98.7%, HPV-18 in 22.8%, HPV-31 in 0.7%, HPV-45 in 1.3%, HPV-52 in 2.0%, HPV-58 in 6.7%, HPV-59 in 4.7%, and HPV-67 in 0.7%. In multivariate analyses, the HPV genotype [HPV-18 or HPV-16 and HPV-18 only versus all others: relative risk (RR), 2.33; 95% CI, 1.17–4.64; P = 0.016] and pre-NAC tumor size (>5 versus ≤5 cm: RR, 2.25; 95% CI, 1.13–4.48; P = 0.021) were significantly related to overall survival. This PCR-based genechip method is sensitive and reproducible for HPV genotyping. The association of HPV-18 or HPV-16 and HPV-18 with poor outcome in cervical carcinoma treated with NAC plus radical surgery is confirmed.

The Impact

The impact of human papillomavirus (HPV) infection on pregnancy is a major problem of medicine. The transmission of the virus from mother to fetus is a process yet unresolved. The immune response and changed hormonal status of pregnant women might facilitate infection. A research on the prevalence of HPV infection was conducted at the Clinic of Obstetrics, Medical University of Lublin (Poland). The studied group included 152 randomly selected women. The material was tested for the presence of HPV DNA by means of polymerase chain reaction (PCR). The aim of the research was to assess the relation between HPV infections detected in the buccal smears of the neonates and the incidence of such infections in the cervical/buccal smears of their mothers. In the group of 152 infants HPV was found in 16 (10.53%). Among the cervical/buccal smears, HPV was isolated, respectively, in 24 (15.79%) and in 19 (12.5%) pregnant women. Statistically significant differences in the prevalence of HPV swabs from the newborns and the cervical/buccal smears of their mothers were found (p< 0.001). The identification of mothers in whose buccal smears HPV was detected can help develop a group of children who run a relatively significant risk of being infected.

Integration of HPV DNA into the host genome is considered to be a key event in malignant transformation. This process results in disruption of El and E2 HPV genes, which is followed by up-regulation of HPV E6 and E7 oncogenes expression. It has been shown in this study that HPV type 16 is the most prevalent high-risk type in women with pathology of the cervix, with the frequency of HPV type 16 detection increasing along with the degree of neoplasia. With the use of real-time polymerase chain reaction the number of HPV type 16 DNA copies and its state were determined in clinical specimens. It was shown that the degree of the disease is associated with viral load and HPV physical state

The purpose of this study was to evaluate the survival of patients with SCC of the oropharynx, according to the presence of HPV and tobacco consumption. A total of 37 patients were followed up for at least 5 years after being diagnosed with SCC of the oropharynx. The biopsy tissue was submitted to the polymerase chain reaction (PCR) and in situ hybridization (ISH) methods for broad determination of HPV presence, to identify the presence of high-risk viruses (16 and 18). 12 of the 37 (32.4%) samples were HPV positive, whereas the two specific types of virus were identified in two samples for HPV-16 and in no samples for HPV-18. We observed no significant effect of the virus in survival analysis, irrespective of tobacco consumption. The level of tobacco consumption was significantly higher in the group of HPV-negative patients (P=0.0283), in which all the patients in this group were smokers. Therefore, HPV did not change the survival of patients with SCC of the oropharynx in this study, indicating that factors other than tobacco need to be studied in conjunction with it, and the level of tobacco consumption is significantly higher in the group of HPV-negative patients.
