Background and objectives: Cervical cancer is one of the leading causes of morbidity and mortality. Human papillomavirus (HPV) is known to be associated with cervical intraepithelial neoplasia (CIN) and cancer. The objective of the present study was to determine the rate of HPV infection among the Bangladeshi women with different grades of CIN and cancer.Methods: Women aged 20 to 55 years, diagnosed as a case of chronic cervicits, cervical intraepithelial neoplasia (CIN) or invasive cancer by Papanicolaou (Pap) smear and colposcopy directed biopsy were enrolled in the study. High and intermediate risk oncogenic HPV were detected in cervical samples by real time PCR (rt-PCR).Results: Seventy two women with chronic cervicitis and different grades of CIN were included in the study. Out of 72 cases, 28 (38.9%) and 44 (61.1%) had chronic cervicitis and CIN respectively. Overall, the HPV infection rate was 43.1% (95% CI= 32%-54%) among the study population. CIN cases had significantly high (p<0.01) HPV infection (78.6%; 95% CI=60%-89%) compared to cases with chronic cervicitis (18.2%; 95% CI=11.1%-34.5%). Women between the age of 20-30 years had the highest positive rate (50.0%) followed by 31- 40 years age group (43.6%). All CIN grade 2 and 3 had HPV infection.Conclusion: The study showed that HPV was strongly associated with different grades of CIN. Specific HPV types should be determined to find out the most prevalent HPV types among the Bangladeshi women with CIN and cervical cancers.IMC J Med Sci 2016; 10(1): 29-32

Aim. Of the study was to assess the clinical and laboratory features of cervical intraepithelial neoplasia (CIN) with persistent human papillomavirus infection and the development of prognostic criteria for persistence of HPV. Materials and methods. The prospective study included 63 patients with HPV-associated CIN. Assessment of persistence of HPV was based on detection of HPV when retesting 12 months. Depending on the results of retesting there were 2 groups: group 1A (main group, n=26), including patients with CIN and HPV persistence after treatment, mean age - 33.69±1.92 years; group 1B (comparison, n=37) - patients with CIN without HPV persistence after treatment, mean age - 34.43±2.09 years. Results. According to the results of the first HPV genotyping (before treatment) among patients of group 1A there was a predominance of two or more HPV types (34.6% vs 16.2% of patients of group 1B; p0.05). According to the results of the second genotyping (12 months after complex treatment) there was a 3.5-fold prevalence of patients with mono-infection against HPV co-infection in group 1A (p

Aims and backround Interferons (IFN) have offered considerable advances in the therapy of genital warts even those associated with cervical intraepithelial neoplasia (CIN); intralesional therapy either alone or in combination with other modalities such as cryosurgery and laser surgery provides improved clearing and cure of these often recalcitrant lesions. The purpose of this study was to evaluate the effectiveness of intralesional IFN therapy in patients with CIN associated with human papillomavirus (HPV) infection. Methods Beta-IFN was injected intra-perilesionally into the cervix in 41 patients with CIN associated with HPV infection. Results The regimen of 3 million international units (IU) injected intralesionally daily in the 1st week and 3 times a week in the 2nd and 3rd weeks for a total of 11 injections and a total dosage of 33 million IU yielded an 80 percent cure rate and may be more advantageous than other treatment options in certain instances. Cytocolposcopic and histologic examination was carried out before and after treatment and 24 lesions were also analyzed for type-specific papillomaviruses using in situ DNA hybridization. CIN disappeared in 33 patients 6 months after the end of therapy. Side effects of intralesional IFN therapy are dose related and for the most part readily tolerated. Conclusions Intralesional IFN proved to be effective treatment for CIN associated with HPV infection (cure rate: 80%) and well accepted because hospitalization is not required and no important side effects occur.

Abstract Persistent infection with high-risk human papillomavirus (HR-HPV) is an important reason for the progression of cervical intraepithelial neoplasia (CIN). Bacterial vaginosis (BV) is a genital infection that frequently presents in women infected with HPV, but the correlation between BV and HPV during CIN development is still elusive. In this study, we enrolled 624 participants and obtained 423 samples of vaginal secretions from them, including 193 HPV-negative samples and 230 HPV-positive samples. We used 16S rRNA sequencing to measure the vaginal microbiota diversity in women with or without BV and HPV co-infection and then calculated risk factors for CIN progression by logistic regression. We found that condom use (OR=3.480; 95% CI=1.069-11.325; P < .05) was a protective factor against CIN, whereas BV (OR=0.358; 95% CI=0.195-0.656; P < .05) and HR-HPV infection (OR= 0.016; 95% CI=0.004-0.072; P < .001) were risk factors for CIN. BV and HPV infection could trigger an increase in the diversity of vaginal microbiota and decrease Lactobacillus domination, which is conducive to CIN regression. The depletion of the carbohydrate metabolism pathway may induce Lactobacillus reduction. Treating BV in the clinical setting could block CIN development and L. iners may be a crucial species during this process.

Abstract: Introduction: Persistent infection of human papillomavirus is known to cause cervical intraepithelial neoplasia or cancer in the cervix uteri and other HPV-associated cancers in different localization. Based on epidemiological and biological data, principally the high risk HPV is responsible for development of cervical these cancers. However, we have no information about the frequently distribution of different HPV types and what is the correlation between the HPV types and cytological diagnosis in cervical intraepithelial neoplasia (CIN). Aim: In this paper, we are going to present new data involving incidence and mortality of HPV-associated cancers during the period of 2009–2015 in Hungary. We are also going to investigate the correlation of cervical cytological diagnosis and HPV typing, and the preventive effect of HPV vaccination. Method: The epidemiological data spring from the National Cancer Registry. HPV typing was performed by Linear Array HPV Genotyping Test. Simultaneous cytological diagnosis and HPV typing was carried out on 2048 cytological samples collected in period of 2009–2016. Results: According to the epidemiologic data, the most frequently occurring HPV-associated cancer is the laryngeal carcinoma in man, and the cervical cancer in woman in Hungary. During the 2009–2015 time intervals, the frequency distribution of head and neck cancers was not changed in man, but the incidence of tongue root squamous cell carcinomas was gradually increasing in woman. We have defined the clinical significance of single and simultaneously multiple HPV infection and have investigated the correlation of the HPV frequency distribution and cytological diagnosis in CIN. It was found that in the cytological negativity of probably/possibly carcinogen pHR-HPV group classified by IACR was much more frequent as in HR-HPV group (56% versus 47%). The presence of simultaneous multiplex HPV infection betokens an increased cancer risk. According to the international publications, the ratio of HPV16 just twice as big as in cervical cancer, what we found in CIN (60% versus 30%). The frequency order of the HPV18 is 2nd in cancer, and 9th in CIN. Comparing the frequency distribution of HR/pHR-HPVs in cervical cancer and CIN, the HR-HPV35 is very rarely occurring in CIN, the pHR-HPV56, 66, and 73 is more frequently seen in CIN as in carcinoma. Appreciated the preventive value of anti-HPV vaccines, we have found a significant differences in group with 1 HPV/sample and in group with more than 1 HPV/sample. Conclusion: The frequency distribution of tongue root squamous cell carcinoma and cervical cancer was gradually increasing in woman. The overall preventive effect of 9-valent vaccine is 80.3%. This preventive value should be higher because of the transformation ability of the different HPV types is not same. Out of consideration for HPV incidence in cancer, the preventive effect of 9-valent or 4-valent vaccines might reach to 93% or 73%. However, the pHR-HPVs are biologically active, it is not sufficient for the inclusion of these HPV types into population-wide HPV-DNA based cervical screening programs.

To compare the prevalence of cervical human papillomavirus (HPV) infection in Turkish women with normal Papanicolaou (Pap) smear and cervical intraepithelial neoplasia (CIN). In between March 2002 and November 2005, the study was designed as case–control study. Cytologic abnormalities in Pap smears were classified according to the Bethesda System (2001). Identification of the presence of HPV was carried out by the Hybrid Capture II test for all patients. To compare the groups, Chi-square test was used. A total of 1353 reproductive aged women were screened. Of them, 1344 (99.3%) had normal or class I Pap smear. Remaining nine cases (0.7%) had CIN at several degrees (five CIN I, three CIN II, and one carcinomain situ). While all these nine cases with cervical pathologies had HPV, only 20 cases from the other group (1.5%) had HPV (χ2466.1;P= 0.0001). This is the first study of the evaluation of the association between HPV and preinvasive cervical lesions in Turkish population. In spite of low general frequency (2.1%) of cervical HPV colonization in this population, a strong correlation was found between HPV and CIN.

Time trends prevalence of human papillomavirus (HPV) genotypes including negative and untypable infections were analyzed during a 15-year period (2005–2019) among 5807 subjects with abnormal pap-smears and/or cervical intraepithelial neoplasia (CIN). The rates of HPV16 dropped by 13% every 3 years (Prevalence Ratio, PR = 0.87, 95% CI = 0.82–0.93) in the CIN1 biopsy, while HPV16 status was unchanged over time in the CIN2+ biopsy. In CIN1 lesions, there was a corresponding increase of HR-HPV types unrelated to nonavalent vaccine. The rates of HPV 18, 31, and 52, decreased by 35% (PR = 0.65, 95% CI = 0.54–0.79), 19% (PR = 0.81, 95% CI = 0.73–0.91), and 21% (PR = 0.79, 95% CI = 0.73–0.86) every 3-year interval in CIN2+, respectively. Overall, the prevalence of negative/untypable HPV specimens in the entire database increased from 9.6% (129/1349) in the period 2011–2013 to 17.6% (161/913) and 28.4% (224/790) in the 2014–2016 period and in the 2017–2019 period, respectively (PR = 1.69,95% CI = 1.52–1.88). HPV 16 prevalence decreased significantly among subjects with low-grade cervical squamous lesions. A significant increase of both HPV types unrelated to nonavalent vaccination and negative/untypable HPV infections was reported. The prevalence of HPV types among subjects with abnormal pap smears in Northern Italy is changing. Many variables including demographic factors and possibly vaccination could be responsible for this modification.

There are more supports for the view that human papillomavirus (HPV) infection might be an etiological factor in the development of cervical cancer when the association of persistent condylomata is considered. Biopsies from 318 cases with squamous cell carcinoma of uterine cervix, 48 with cervical and vulvar condylomata, 14 with cervical intraepithelial neoplasia (CIN), 34 with chronic cervicitis and 24 normal cervical epithelium were collected from 5 geographic regions of China with different cervical cancer mortalities. All specimens were prepared for Dot blot, Southern blot and in situ DNA-DNA hybridizations by using HPV-11, 16, 18 DNA labelled with 32P and 3H as probes to detect viral homologous sequences in samples. Among them, 32 cases with cervical cancer, 27 with condyloma and 10 normal cervical epitheliums were randomly chosen for comparative EM observation. The results showed that: 1), 192 out of 318 (60.4%) cases of cervical cancer were positive for HPV-16 DNA probe (Table I)
