Background: Cervical cancer remains a major public health problem worldwide – particularly in less developed countries. Around 85% of their new cases and 86% of deaths occur in less development countries (IARC, 2012). In Bangladesh, Cervical cancer is the second most common disease among female with an estimated 11,956 new cases and 6,582 deaths in 2012. Objectives: The present study was undertaken to identify the Effects of Human Papillomavirus infection with Pre-invasive cervical lesions in Bangladesh. Methods: This cross sectional study was carried out at the colposcopy clinic of Gynaecology and Obstetrics department of Bangabandhu Sheikh Mujib Medical University during the study period January 2015 - December 2015. A total of 65 consecutive women with VIA +ve cases of all three grades of CIN (CIN I, CIN II, CIN III) were enrolled in this study. Women having invasive cervical disease and women who not interested were excluded from this study. Results: More than one third (35.3%) patients were in 3rd decade. More than one third (35.4%) patients had normal colposcopic findings followed by 23(35.4%) was CIN I, 11(16.9%) was CIN II and 8(12.3%) was CIN III. Majority (42.6%) patients was found CIN I, 11(26.1%) was CIN II, 8(19.4%) was CIN III and 5(11.9%) had normal in Histopathology. CIN I histopathological finding was found 18 cases, among them 8(44.4%) in positive HC-2/Viral load/ RLU index. In multivariate analysis CIN III was significantly increased 1.34 times in HC-2/Viral load/RLU index positive (human Papillomavirus) cases (95% CI 0.22 – 8.9%, <0.05). Validity test of benign HPV DNA test of the study women showed that HPV DNA had sensitivity 51.4%, specificity 92.9%, accuracy 69.2%, positive predictive values 90.5% and negative predictive values 59.1%. Benign Colposcopic finding had had sensitivity 86.5%, specificity 64.3%, accuracy 76.9%, positive predictive values 76.2% and negative predictive values 78.3%. CIN III significantly 1.34 times increased HC-2/Viral load/ RLU index positive (human Papillomavirus) in multivariate analysis. Conclusion: From the findings of the study it was observed that colposcopy had a high sensitivity and optimum specificity; HPV DNA test had lower sensitivity and higher specificity. Colposcopic findings were closely associated with Histopathology, where the validity test was high when compared to HPV DNA test. So it can be concluded that the Colposcopy is a useful screening test for detection of cervical lesions and Human Papillomavirus is associated with pre-invasive cervical lessons. So the HPV DNA test can be used as a co-test with Colposcopy for screening of cervical lesions. Bangladesh J Obstet Gynaecol, 2018; Vol. 33(1) : 5-10

The line blot assay, a gene amplification method that combines PCR with nonisotopic detection of amplified DNA, was evaluated for its ability to detect human papillomavirus (HPV) DNA in genital specimens. Processed samples were amplified with biotin-labeled primers for HPV detection (primers MY09, MY11, and HMB01) and for β-globin detection (primers PC03 and PC04). Amplified DNA products were hybridized by a reverse blot method with oligonucleotide probe mixtures fixed on a strip that allowed the identification of 27 HPV genotypes. The line blot assay was compared to a standard consensus PCR test in which HPV amplicons were detected with radiolabeled probes in a dot blot assay. Two hundred fifty-five cervicovaginal lavage specimens and cervical scrapings were tested in parallel by both PCR tests. The line blot assay consistently detected 25 copies of HPV type 18 per run. The overall positivity for the DNA of HPV types detectable by both methods was 37.7% (96 of 255 samples) by the line blot assay, whereas it was 43.5% (111 of 255 samples) by the standard consensus PCR assay. The sensitivity and specificity of the line blot assay reached 84.7% (94 of 111 samples) and 98.6% (142 of 144 samples), respectively. The agreement for HPV typing between the two PCR assays reached 83.9% (214 of 255 samples). Of the 37 samples with discrepant results, 33 (89%) were resolved by avoiding coamplification of β-globin and modifying the amplification parameters. With these modifications, the line blot assay compared favorably to an assay that used radiolabeled probes. Its convenience allows the faster analysis of samples for large-scale epidemiological studies. Also, the increased probe spectrum in this single hybridization assay permits more complete type discrimination.

Introduction: Infection with HPV is the main cause of cervical cancer. Determining HPV infection and the types of HPV plays an important role in diagnosis, treatment and prognosis of cervicitis/cervical cancer. Aims: Determining proportion of high-risk HPV types and the occurrence of coinfection with multiple HPV types. Methods: 177 women with cervicitis or abnormal Pap smear result were enrolled in the study. Performing the real-time PCR for detecting HPV and the reverse DOT-BLOT assay for determining type of HPV in cases of positive PCR. Results: 7 types of high-risk HPV was dectected, the majority of these types were HPV type 18 (74.6%) and HPV type 16 (37.6%); the proportion of infection with only one type of HPV was 30.4% and coinfection with multiple HPV types was higher (69.6%), the coinfected cases with 2 and 3 types were dominated (32.2% and 20.3%, respectively) and the coinfected cases with 4 and 5 types were rare. Conclusion: Use of the real-time PCR and reverse DOT-BLOT assay can determine the high-risk HPV types and the occurrence of coinfection with multiple HPV types. Key words: HPV type, Reverse DOT-BLOT, real-time PCR,PCR, cervical cancer

Objective: A vast majority of cervicovaginal intraepithelial lesions are caused by high-risk human papillomaviruses (HPVs). The Pap test has been the sole method used for the screening of cervicovaginal squamous intraepithelial lesions (SIL). Recently, the FDA approved an HPV-DNA assay as a method of primary screening. We report on a series of FDA-approved HPV-DNA test-negative SIL with HPV genotyping, using an alternative method on the corresponding surgical biopsy specimens. Study Design: A retrospective review identified cytology-positive HPV-negative cases over a 15-month period at a tertiary care gynecologic oncology institution. Corresponding biopsies were reviewed and genotyped for high-risk HPVs. Results: Of the 18,200 total cases, 17 patients meeting the study criteria were selected with 27 surgical specimens corresponding to their cytologic diagnoses. Four patients with high-grade lesions were identified, 3 of whom (75%) were positive for HPV. One of these 4 patients (25%) showed high-grade SIL on biopsies from 4 separate sites in the cervix and vagina. Multiviral HPV infections were frequent. Conclusions: We discuss the relevance of cotesting for screening cervical SILs and emphasize that false-negative results are possible with the FDA-approved HPV screening assay, also in patients with high-grade SIL. These cases may be detectable by cytologic examination and this suggests that the Pap test remains an important diagnostic tool.
