    OBJECTIVE: The study aimed to evaluate E6 and E7 oncoproteins of HPV16 and HPV18 expression in formalin - fixed paraffin embedded (FFPE) tissue in different grades of the cervical lesion and evaluate the potential use of E6 and E7 oncoproteins derived from HPV 16 and 18 as diagnostic protein biomarkers for triaging cervical lesions.

    METHODOLOGY: A total of 102 FFPE cervical tissues were collected from 2 tertiary hospitals and immunohistochemical reactivity staining of E6 and E7 oncoproteins of HPV16 and HPV18 were evaluated using immunoreactive scoring (IRS) system and analysed statistically.

    RESULT: The result showed an increased oncoprotein expression with the progression of cervical lesions. There is a statistically significant association between histology grade and HPV16/18-E6 expression (p = 0.028). However, there are no significant association of histological grade to HPV16-E7 immunoreactivity score (p = 0.264) and HPV18-E7 (p=0.080).

    CONCLUSION: The immunohistochemical expression of HPV oncoproteins is a potential alternative diagnostic tool applicable in a low-resource laboratory setting. The advantage of the histochemical evaluation is that this method is simpler to apply and less expensive in comparison to in situ mRNA hybridization. Nevertheless, our study also found that antibodies against HPV that are commercially available suffer quite substantial specificity issues such as background staining and inconsistency between different batches. Hence, the utilization of antibody-based staining warrants stringent quality control.

    Australia's cervical screening program transitioned from cytology to HPV-testing with genotyping for HPV16/18 in Dec'2017. We investigated whether program data could be used to monitor HPV vaccination program impact (commenced in 2007) on HPV16/18 prevalence and compared estimates with pre-vaccination benchmark prevalence. Pre-vaccination samples (2005-2008) (n = 1933; WHINURS), from 25 to 64-year-old women had been previously analysed with Linear Array (LA). Post-vaccination samples (2013-2014) (n = 2989; Compass pilot), from 25 to 64-year-old women, were analysed by cobas 4800 (cobas), and by LA for historical comparability. Age standardised pre-vaccination HPV16/18 prevalence was 4.85% (95%CI:3.81-5.89) by LA; post-vaccination estimates were 1.67% (95%CI:1.21-2.13%) by LA, 1.49% (95%CI:1.05-1.93%) by cobas, and 1.63% (95%CI:1.17-2.08%) for cobas and LA testing of non-16/18 cobas positives (cobas/LA). Age-standardised pre-vaccination oncogenic HPV prevalence was 15.70% (95%CI:13.79-17.60%) by LA; post-vaccination estimates were 9.06% (95%CI:8.02-10.09%) by LA, 8.47% (95%CI:7.47-9.47%) by cobas and cobas/LA. Standardised rate ratios between post-vs. pre-vaccination rates were significantly different for HPV16/18, non-16/18 HPV and oncogenic HPV: 0.34 (95%CI:0.23-0.50), 0.68 (95%CI:0.55-0.84) and 0.58 (95%CI:0.48-0.69), respectively. Additional strategies (LA for all cobas positives; combined cobas and LA results on all samples) had similar results. If a single method is applied consistently, it will provide important data on relative changes in HPV prevalence following vaccination.

    BACKGROUND: In several years ago, infection with human papillomaviruses (HPVs), have been prevalent in the worlds especially HPV type 18, can lead to cervical cancer. Therefore, rapid, accurate, and early diagnosis of HPV for successful treatment is essential. The present study describes the development of a selective and sensitive electrochemical biosensor base on DNA, for early detection of HPV-18. For this purpose, a nanocomposite of reduced graphene oxide (rGO) and multiwalled carbon nanotubes (MWCNTs) were electrodeposited on a screen-printed carbon electrode (SPCE). Then, Au nanoparticles (AuNPs) were dropped on a modified SPCE. Subsequently, single strand DNA (ssDNA) probe was immobilized on the modified electrode. The link attached between AuNPs and probe ssDNA provided by L-cysteine via functionalizing AuNPs (Cys-AuNPs). The differential pulse voltammetry (DPV) assay was also used to electrochemical measurement. The measurement was based on the oxidation signals of anthraquninone-2-sulfonic acid monohydrate sodium salt (AQMS) before and after hybridization between the probe and target DNA.

    RESULTS: The calibration curve showed a linear range between 0.01 fM to 0.01 nM with a limit of detection 0.05 fM. The results showed that the optimum concentration for DNA probe was 5 µM. The good performance of the proposed biosensor was achieved through hybridization of DNA probe-modified SPCE with extracted DNA from clinical samples.

    CONCLUSIONS: According to the investigated results, this biosensor can be introduced as a proprietary, accurate, sensitive, and rapid diagnostic method of HPV 18 in the polymerase chain reaction (PCR) of real samples.

    Cervical cancer is the fourth most common cancer among women. Infection by high-risk human papillomavirus (HPV) is the main aetiology for the development of cervical cancer. Infection by high-risk human papillomavirus (HPV) and the integration of the HPV genome into the host chromosome of cervical epithelial cells are key early events in the neoplastic progression of cervical lesions. The viral oncoproteins, mainly E6 and E7, are responsible for the initial changes in epithelial cells. The viral proteins inactivate two main tumour suppressor proteins, p53, and retinoblastoma (pRb). Inactivation of these host proteins disrupts both the DNA repair mechanisms and apoptosis, leading to rapid cell proliferation. Multiple genes involved in DNA repair, cell proliferation, growth factor activity, angiogenesis, as well as mitogenesis genes become highly expressed in cervical intraepithelial neoplasia (CIN) and cancer. This genomic instability encourages HPV-infected cells to progress towards invasive carcinoma. The key molecular events involved in cervical carcinogenesis will be discussed in this review.

    Human papillomavirus (HPV) plays an important role in the pathogenesis of cervical cancer. HPV has been found in 99.7% of cervical cancers worldwide. In Malaysia, it is the second most common cancer among women in all major ethnic groups. The main purpose of this study was to establish the method of SyBrGreen Real-Time PCR and apply it for identification of multiple infections of the two high risk HPV subtypes. In this study, 57 positive samples for HPV 16 and HPV 18 were used to establish a simple
    and sensitive method to detect and identify HPV infection in the cervical neoplasia at different stages of the disease by using real-time ABICycler SyBrGreen 1 technology. The results showed 67 HPV genomes in 57 samples. HPV 16 genome was detected in 55/67 (82%) cases while HPV 18 was detected in 8/67 (12%) cases with 4 cases showing multiple infections of HPV 16 and HPV 18. HPV 16 was the most prevalent followed by HPV 18. Using SyBr Green Real-Time PCR techniques, the results
    showed that DNA melting curve for HPV 16 had a peak around 80.2ºC and Ct value of 20 cycles whereas the DNA melting curve for HPV 18 around 79.2ºC and Ct value of 22 cycles. In conclusion, a SyBr Green Real-Time PCR method has the potential for clinical usage in detection and identification of HPV infection in cervical neoplasia at different stages of the disease.

    To increase the coverage of HPV vaccination, Malaysia implemented a national school-based vaccination program for all 13-year-old girls in 2010. Two years later, a clinic-based catch-up program was started for 16 to 21-year-old girls. We assessed the prevalence of a range of HPV genotypes, among a sample of urban women within the age groups of 18-24 and 35-45 years in 2019-2020, a decade into the national vaccination program. The HPV prevalence was then compared to that reported in an unvaccinated population in 2013-2015. We sampled a total of 1134 participants, comprising of 277 women aged 18-24 years and 857 women aged 35-45 years, from several urban clinics in the state of Selangor. Participants provided a self-acquired vaginal sample for HPV genotyping. Comprehensive sociodemographic and vaccination history were collected. The HPV vaccination coverage among women in the younger age group increased from 9.3% in 2013-2015 to 75.5% in 2019-2020. The prevalence of vaccine-targeted HPV16/18 decreased 91% (CI: 14.5%-99.0%) among the younger women, from 4.0% in 2013-2015 to 0.4% in 2019-2020. There was also an 87% (CI: 27.5%-97.5%) reduction in HPV6/11/16/18. There was no difference in the prevalence of non-vaccine targeted HPV genotypes among younger women. The HPV prevalence among older women, for both vaccine targeted and non-vaccine targeted genotypes in 2019-2020, did not differ from 2013-2015. The observed decline in prevalence of vaccine-targeted HPV genotype among younger women a decade after the national HPV vaccination program is an early indication of its effectiveness in reducing the burden of cervical cancer.

    Cervical carcinoma, the second most common malignancy in Malaysian females, is aetiologically linked to the human papillomavirus (HPV). A study was conducted at the Department of Pathology, University of Malaya Medical Centre to compare the identification of HPV 6, 11, 16 and 18 in 40 archived formalin-fixed, paraffin-embedded cervical carcinoma by non-isotopic in-situ hybridisation (NISH) and polymerase chain reaction (PCR). HPV L1 ORF consensus PCR was also carried in cases which were negative on HPV type-specific PCR. NISH detected HPV 16 in 13 (32.5%) cases with one case demonstrating a concomitant HPV 18. beta-globin DNA PCR was carried out on the same paraffin block as for NISH in 27 cases and on a different paraffin block in 13, with amplification in 9 of the former and 3 of the latter. Thus only 12 cases were subjected to further HPV PCR. HPV was detected in 10 (83.3%) with HPV 16 in 9 cases and HPV L1 ORF in one. When using the same paraffin block for both methods of HPV detection, NISH detected HPV in 6 and PCR in 7. NISH failed to detect HPV in a case detected by PCR. 2 cases were negative for HPV using both methods. Hence, HPV detection results by NISH and PCR were concordant in 88.9%. Interestingly, NISH detected HPV in 2 cases with non-amplifiable beta-globin DNA. Using an alternative paraffin block for HPV PCR from NISH, HPV DNA was detected in 3 cases, two of which also showed type-specific positivity on NISH. The third case did not reveal type-specific positivity with NISH or PCR but demonstrated HPV DNA on L1 ORF consensus PCR. It thus appears that PCR and NISH can be successfully used to detect HPV in formalin-fixed, paraffin-embedded tissue and in the presence of intact DNA NISH may be as sensitive as PCR.

    Cervical cancer remains one of the leading causes of cancers in women from Indonesia, Malaysia, the Philippines, Thailand and Vietnam. High-risk human papillomavirus (HPV) types, particularly HPV-16 and 18, are consistently identified in cervical cancer cases regardless of geographical region. Factors that have been identified to increase the likelihood of HPV exposure or subsequent development of cervical cancer include young age at first intercourse, high parity and multiple sexual partners. Cervical cancer screening programs in these countries include Pap smears, single visit approach utilizing visual inspection with acetic acid followed by cryotherapy, as well as screening with colposcopy. Uptake of screening remains low in all regions and is further compounded by the lack of basic knowledge women have regarding screening as an opportunity for the prevention of cervical cancer. Prophylactic HPV vaccination with the quadrivalent vaccine has already been approved for use in Malaysia, the Philippines and Thailand, while the bivalent vaccine has also been approved in the Philippines. However, there has been no national or government vaccination policy implemented in any of these countries.

    The High-Risk Human Papillomaviruses (HR-HPVs) 16 and 18 are known to cause cervical cancer, which is primarily attributed to E6 and E7 oncoproteins. In addition, recent studies have focused on the vital role of the p130 pocket protein as an oncosuppressor to limit the expression of E2F transcription factors required for cell cycle progression. In view of this, the current study was conducted to investigate the mechanism by which transfection with HPV16/18 E7 leads to the deregulation of the host cell cycle, altering the localisation of p130, and expression of differentiation genes in Human Keratinocytes (HaCaT) cells. Co-immunoprecipitation, Western blot analysis, immunofluorescence microscopy, flow cytometry, quantitative-Polymerase Chain Reaction (qPCR), and the inhibition of p130 by MG132 inhibitor were employed to investigate the loss of p130 and its disruption in HPV 16/18 E7-transfected HaCaT cells. The HPV16- and HPV18-transformed cells, known as CaSki and HeLa, respectively, were also used to complement the ectopic expressions of E7 in HaCaT cells. Normal keratinocytes displayed higher level of p130 expression than HPV-transformed cells. In addition, the immunofluorescence analysis revealed that both HPV 16/18 E7-transfected HaCaT and HPV-transformed cells exhibited higher level of cytoplasmic p130 compared to nuclear p130. A significant increase in the number of S/G2 phase cells in HPV-transformed cells was also recorded since E7 has been shown to stimulate proliferation through the deactivation of Retinoblastoma Protein (pRB)-dependent G1/S checkpoint. Furthermore, the findings recorded the down-regulation of keratinocyte differentiation markers, namely p130, keratin10, and involucrin. The proteasomal degradation of the exported p130 confirmed the cellular localisation pattern of p130, which was commonly observed in cancerous cells. The findings provide strong evidence that the localisation of nuclear p130 nuclear was disrupted by HPV16/18 E7 led to the deregulation of the cell cycle and the impairment of cellular differentiation ultimately lead to cellular transformation.

    OBJECTIVES: High-risk human papillomavirus (HR-HPV) viral load is associated with HR-HPV transmission and HR-HPV persistence in women. It is unknown whether HR-HPV viral load is associated with persistence in HIV-negative or HIV-positive men.
    METHODS: HR-HPV viral load and persistence were evaluated among 703 HIV-negative and 233 HIV-positive heterosexual men who participated in a male circumcision trial in Rakai, Uganda. Penile swabs were tested at baseline and 6, 12 and 24 months for HR-HPV using the Roche HPV Linear Array, which provides a semiquantitative measure of HPV shedding by hybridisation band intensity (graded: 1-4). Prevalence risk ratios (PRR) were used to estimate the association between HR-HPV viral load and persistent detection of HR-HPV.
    RESULTS: HR-HPV genotypes with high viral load (grade:3-4) at baseline were more likely to persist than HR-HPV genotypes with low viral load (grade: 1-2) among HIV-negative men (month 6: adjPRR=1.83, 95% CI 1.32 to 2.52; month 12: adjPRR=2.01, 95% CI 1.42 to 3.11), and HIV-positive men (month 6: adjPRR=1.33, 95% CI 1.06 to 1.67; month 12: adjPRR=1.73, 95% CI 1.18 to 2.54). Long-term persistence of HR-HPV was more frequent among HIV-positive men compared with HIV-negative men (month 24: adjPRR=2.27, 95% CI 1.47 to 3.51). Persistence of newly detected HR-HPV at the 6-month and 12-month visits with high viral load were also more likely to persist to 24 months than HR-HPV with low viral load among HIV-negative men (adjPRR=1.67, 95% CI 0.88 to 3.16).
    CONCLUSIONS: HR-HPV genotypes with high viral load are more likely to persist among HIV-negative and HIV-positive men, though persistence was more common among HIV-positive men overall. The results may explain the association between high HR-HPV viral load and HR-HPV transmission.

    BACKGROUND: An estimated 70% of cervical cancers worldwide are attributable to persistent infection with human papillomaviruses (HPV) 16 and 18. Vaccination against HPV 16/18 has been shown to dramatically reduce the incidence of associated precancerous and cancerous lesions. The aims of the present analyses were, firstly, to estimate the clinical and economic burden of disease attributable to HPV in Malaysia and secondly, to estimate long-term outcomes associated with HPV vaccination using a prevalence-based modeling approach.

    METHODS: In the first part of the analysis costs attributable to cervical cancer and precancerous lesions were estimated; epidemiologic data were sourced from the WHO GLOBOCAN database and Malaysian national data sources. In the second part, a prevalence-based model was used to estimate the potential annual number of cases of cervical cancer and precancerous lesions that could be prevented and subsequent HPV-related treatment costs averted with the bivalent (HPV 16/18) and the quadrivalent (HPV 16/18/6/11) vaccines, at the population level, at steady state. A vaccine efficacy of 98% was assumed against HPV types included in both vaccines. Effectiveness against other oncogenic HPV types was based on the latest results from each vaccine's respective clinical trials.

    RESULTS: In Malaysia there are an estimated 4,696 prevalent cases of cervical cancer annually and 1,372 prevalent cases of precancerous lesions, which are associated with a total direct cost of RM 39.2 million with a further RM 12.4 million in indirect costs owing to lost productivity. At steady state, vaccination with the bivalent vaccine was estimated to prevent 4,199 cervical cancer cases per year versus 3,804 cases for the quadrivalent vaccine. Vaccination with the quadrivalent vaccine was projected to prevent 1,721 cases of genital warts annually, whereas the annual number of cases remained unchanged with the bivalent vaccine. Furthermore, vaccination with the bivalent vaccine was estimated to avert RM 45.4 million in annual HPV-related treatment costs (direct+indirect) compared with RM 42.9 million for the quadrivalent vaccine.

    CONCLUSION: This analysis showed that vaccination against HPV 16/18 can reduce the clinical and economic burden of cervical cancer and precancerous lesions in Malaysia. The greatest potential economic benefit was observed using the bivalent vaccine in preference to the quadrivalent vaccine.

    INTRODUCTION: Cervical cancer is the third most common cancer in women worldwide. The HPV-16/18 AS04- adjuvanted vaccine (Cervarix©) has previously been shown to be highly immunogenic with a clinically acceptable safety profile. This phase IIIb, double-blind, randomized (1:1) and placebo controlled trial (NCT00345878) was designed to evaluate the vaccine immunogenicity against HPV-16 and HPV-18 as well as its safety and reactogenicity in Malaysian women.

    METHODS: Healthy women aged 18-35 years received intramuscularly three doses of either the vaccine (HPV group) or aluminium hydroxide (ALU group) at 0, 1, and 6 months. Antibody titers were measured by an enzyme-linked immunosorbent assay (ELISA).

    RESULTS: A total of 271 eligible subjects were enrolled and 266 subjects completed the study. Initially seronegative subjects in the HPV group showed 100% seroconversion one month post-dose-3 for anti HPV-16 and anti-HPV-18 antibodies with geometric mean titers of 11107.5 (95% CI: 9727.3-12683.4) EL.U/mL and 4273.5 (95% CI: 3771.8-4841.9) EL.U/mL, respectively. Over 96% of subjects in both groups received all three vaccine doses. Solicited local (pain) and general symptoms (myalgia, fatigue, arthralgia and headache) were commonly reported in both HPV and ALU groups. Eight serious adverse events were reported throughout the study (five in the HPV group; three in the ALU group), all considered by investigators to be unrelated to vaccination.

    CONCLUSION: The HPV-16/18 AS04-adjuvanted vaccine was immunogenic and generally well tolerated in Malaysian women aged 18-35 years.

    Introduction: Cervical cancer remains the second commonest female malignancy worldwide and the seventh among Malaysians. Globally in 2012, an estimated 528 000 women developed cervical cancer and almost 266 000 died from this disease. Of all cervical cancers, 83% occur in the less developed world due to the absence of screening. To promote the community health awareness of cervical cancer which is preventable. Methods: By internet literature searching (Google Scholar) and textbooks. Results: The primary cause of cervical pre-cancer and cancer is persistent infection with one or more of the oncogenic types of HPV, the most common infection acquired during sexual inter-course, usually early in sexual life. Cervical cancer due to HPV can be prevented by HPV vaccination, participation in a screening program, avoidance of smoking, limitation of sex partners and use of a condom. Three HPV vaccines are available worldwide such as bivalent HPV 16/18 vaccine, quadrivalent HPV 16/18/6/11 L1 virus-like particles vaccine and 9-valent HPV 6/11/16/18/31/33/45/52/58 recombinant vaccine. The HPV test can be done on the same sample of cells collected from the Pap test and it can help to know HPV types. Conclusion: Cervical cancer due to HPV can be prevented by vaccination and the pre-cancerous phase of cervical cancer can be screened by the HPV testing with the Pap test. The community health awareness plays a major role in cervical cancer prevention.

    This study aims to determine the acceptability of Human Papilloma Virus (HPV) self-sampling and the factors associated with willingness to buy HPV self-sampling kit in the future. A total of 164 women aged 28-60 years old from Obstetrics & Gynaecology clinics at a teaching hospital performed HPV self-sampling using the Digene HC2 DNA collection kit. After samples were taken, the participants were given self-administered questionnaires. The majority of the participants were Malay (93.9%), had attained tertiary education (65.2%) and were employed (70.1%). The acceptability was good. More than half of the participants felt that self-sampling was easy. Only 1.2% felt that the procedure was difficult to perform. Most reported no pain at all during the procedure (66.9%). The commonest concern was getting a good sample (90.1%). A number of Pap smears were found to be significantly associated with the willingness to buy the HPV self-sampling kit. HPV self-sampling has the potential to be included in the cervical cancer screening programme. Impact Statement What is already known on this subject: HPV self-sampling is acceptable in some developed and developing countries. It is acceptable because it was easy to perform with very minimal pain or discomfort. Studies on the acceptance of self-screening are needed to plan a policy on self-sampling in the future. What the results of this study add: Our study adds new findings to the body of knowledge on self-sampling in the local population. We found that more women are willing to do the self-sampling at the clinic rather than at home. Although more than 90% expressed willingness to do self-sampling in the future, only 70% of them were willing to purchase the kit. Cost is a potential barrier to women who have the interest to perform the self-sampling. Given the global economic challenges, cost is inevitably an important predictor that we have to consider. What the implications are of these findings for clinical practice and/or further research: Future research should examine women from the rural areas and those who are resilient to Pap smear screening. In clinical practice, clinicians should acknowledge that cost is a potential barrier for women who are willing to do self-sampling. Self-sampling could be an option for women with no financial constraint to buy the kit. However, clinicians should counsel women so that they can make an informed choice in determining their screening method.
