[PMID: 39131793 PMCID: PMC11311752 DOI: 10.5339/qmj.2024.33] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2024] [Accepted: 06/09/2024] [Indexed: 08/13/2024] Open
Abstract
Background Cervical cancer remains a global health challenge, claiming the lives of millions annually and having a significant impact on Gulf Cooperation Council (GCC) countries. Human papillomavirus (HPV), the primary causative agent, plays a central role, with regional variations in prevalence.1 The process from HPV infection to neoplastic changes takes 5-25 years to occur, hence, knowing its prevalence in our community is vital.2. Methods PubMed and SCOPUS were searched to identify articles related to cervical and anogenital HPV prevalence and genotypes in Qatar, Kuwait, Bahrain, Oman, the United Arab Emirates (UAE), and the Kingdom of Saudi Arabia (KSA) published between 2017 and 2024. Results A total of 19 articles were included in this review. Eight studies were from KSA, four were from Kuwait, three were from the UAE, one was from Qatar, Oman, and Bahrain, and one presented data collectively from the KSA, UAE, Qatar, and Bahrain. The prevalence of HPV ranged between 4.7% and 77% in studies from the KSA, between 15% and 54.3% in studies from Kuwait, between 14.7% and 88% in studies from the UAE, was 8.1% and 31.3% in the two studies from Qatar, and was 17.8% and 20% in the studies from Oman and Bahrain, respectively. HPV 16 was the most prevalent high-risk genotype found in studies conducted in the KSA, UAE, Kuwait, and Qatar. In Oman, HPV 82 predominated. In Bahrain, the majority had other non-HPV 16/18/45 genotypes. In the UAE and Kuwait, HPV 11 was the predominant low-risk type, followed by HPV 6. In Qatar, HPV 81 was the most common low-risk type, followed by HPV 11. In Oman, HPV 54 was the most common low-risk type, followed by HPV 42. Conclusion There are no studies with data on HPV prevalence and genotypes among women who have been vaccinated against HPV in GCC countries.

Knowledge of cervical cancer screening among Omani women attending a university teaching hospital: a cross-sectional study. BMC Womens Health 2024; 24:40. [PMID: 38218830 PMCID: PMC10787955 DOI: 10.1186/s12905-023-02870-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2023] [Accepted: 12/26/2023] [Indexed: 01/15/2024] Open
Abstract
OBJECTIVES To assess knowledge, attitudes, and practices regarding cervical cancer and Pap smear screening among Omani women attending a tertiary clinic in Muscat, Oman, and to establish correlations with selected sociodemographic factors. METHODS An observational, cross-sectional study was carried out among Omani women aged 18-50 years old attending the outpatient clinic of the Department of Obstetrics and Gynecology, Sultan Qaboos University Hospital, from October 2019 to February 2020. A validated Arabic-language questionnaire was utilized to collect data regarding the participants' sociodemographic characteristics, their knowledge of cervical cancer and related risk factors, and their knowledge, attitudes, and practices related to cervical cancer screening and Pap smear testing. RESULTS Of the 380 respondents, 86 and 55% had previously heard of cervical cancer and Pap smear testing, respectively; however, only 26% were knowledgeable concerning these topics. Knowledge scores were significantly associated with various sociodemographic factors, including marital status and a previous awareness of cervical cancer (odds ratio: > 1, p < 0.05). Only 21% had themselves previously undergone Pap smear testing; however, 75% reported being willing to undergo such screening in future. CONCLUSIONS Knowledge regarding cervical cancer-related risk factors and Pap smear screening was poor among a cohort of Omani women attending a tertiary clinic in Muscat, Oman. This may play a role in the increased frequency of cervical cancer cases observed in Oman over recent years. As such, a well-structured public education program is recommended to raise awareness of this issue.

Exploring the prevalence of Human Papillomavirus (HPV) genotypes in PAP smear samples of women in northern region of United Arab Emirates (UAE): HPV Direct Flow CHIP system-based pilot study. PLoS One 2023; 18:e0286889. [PMID: 37672534 PMCID: PMC10482270 DOI: 10.1371/journal.pone.0286889] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Accepted: 08/21/2023] [Indexed: 09/08/2023] Open
Abstract
OBJECTIVE The aim of this study was to explore the prevalence of low and high-risk HPV genotypes in PAP smear samples of women in northern region of the UAE using HPV direct flow CHIP method. METHODS A cross-sectional retrospective study was conducted between September 2021 to April 2022. A total of 104 liquid-based cervical cytology samples were obtained from women aged 20-59 years attending the Gynaecology out-patient department of Thumbay University Hospital and other hospitals of Northern Emirates of UAE, processed for the routine cytological examination to identify and differentiate morphological changes of the PAP smear samples. HPV genotyping was performed using HPV direct flow CHIP method. RESULTS In total, 112 HPV genotypes were detected in 63 women (60.57%) included 18 abnormal cytological and 45 normal epithelial samples. 63 LR and 49 HR HPV genotypes were identified in all the 63 positive samples. Highest rate of infection with multiple LR and HR HPV genotypes were detected in women aged 40-49 years (25.9%) and 20-29 years (23.5%). Infection by HPV6 (13.46%), HPV11 (9.61%), HPV16 (9.61%), HPV62/81 (7.69%) and HPV45 (7.69%) were the most common genotypes. A moderate increase than expected incidence of HPV45 and 62/81 (7.69%) were detected. Co-infection with multiple low and high-risk genotypes is present in 20.2% cases; in that, HPV6 (15.9%) was the most common followed by HPV62/81 (12.7%) and HPV16 (11.11%). The prevalence of HPV18 was found to be 1.6%. CONCLUSION The genotypes 6, 45, 16, 11, 67, 62/81 were the most common HPV infections in the women between the age group of 21 and 59-years-old. A moderate increase of HPV45, 62/81 and much less prevalence of HPV18 were detected in the study population. 43.27% of the normal epithelia were positive to different low and high-risk HPV genotypes. This finding highlights the importance of molecular genotyping of HPV to emphasize the cervical screening triage.

Type distribution of human papillomaviruses in ThinPrep cytology samples and HPV16/18 E6 gene variations in FFPE cervical cancer specimens in Fars province, Iran. Cancer Cell Int 2023; 23:166. [PMID: 37568237 PMCID: PMC10422805 DOI: 10.1186/s12935-023-03011-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Accepted: 07/28/2023] [Indexed: 08/13/2023] Open
Abstract
BACKGROUND There exists strong evidence that human papillomavirus (HPV) is associated with cervical cancer (CC). HPV E6 is a major oncogene whose sequence variations may be associated with the development of CC. There is not sufficient data on the distribution of HPV types in ThinPrep cytology specimens and HPV 16/18 E6 gene variations among CC patients in the southwest of Iran. This study was conducted to contribute to HPV screening and vaccination in Iran. METHODS A total of 648 women screened for cervicitis, intraepithelial neoplasia or CC were included in the study. All participants underwent ThinPrep cytology testing, single-step HPV DNA detection and allele-specific reverse hybridization assays. Moreover, a total of 96 specimens previously tested positive for single infection with HPV16 or 18 were included for variant analysis. HPV16/18 lineages and sublineages were determined by PCR assays followed by sequencing the E6 gene and the construction of neighbor-joining phylogenetic trees. RESULTS Overall, HPV DNA was detected in 62.19% of all the screened subjects. The detection rates of HPV DNA among individuals with normal, ASC-US, ASC-H, LSIL, and HSIL cervical cytology were 48.9%, 93.6%, 100%, 100%, and 100%, respectively. Low-risk HPVs were detected more frequently (46.9%) than high-risk (38.9%) and possible high-risk types (11.1%). Of 403 HPV-positive subjects, 172 (42.7%) had single HPV infections while the remaining 231 (57.3%) were infected with multiple types of HPV. Our results indicated a remarkable growth of high-risk HPV66 and 68 and low-risk HPV81 which have rarely been reported in Iran and HPV90 and 87 that are reported for the first time in the country. In addition, 3 lineages (A, D, and C) and 6 sublineages (A1, A2, A4, C1, D1, and D2) of HPV16, and one lineage and 4 sublineages (A1, A3, A4, and A5) of HPV18 were identified. The studied HPV16 and 18 variants mainly belonged to the D1 and A4 sublineages, respectively. CONCLUSION The present study suggests that the prevalence of HPV infection in women of all age groups with or without premalignant lesions in the southwestern Iran is high and the predominant HPV types in the southwest of Iran may differ from those detected in other parts of the country. This study also highlights the necessity of not only initiating HPV vaccination for the general population but also developing new vaccines that confer immunity against the prevalent HPV types in the area and national cervical screening programs using a combination of thinPrep cytology test and HPV detection assays in order to improve the accuracy of the screening.

Knowledge, attitudes and acceptance toward Human papillomavirus (HPV) vaccination: Perspectives of Muslim women and men. Vaccine 2023; 41:2224-2233. [PMID: 36858872 DOI: 10.1016/j.vaccine.2023.02.063] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 02/20/2023] [Accepted: 02/22/2023] [Indexed: 03/03/2023]
Abstract
OBJECTIVES Human papillomavirus (HPV) infection is the leading risk factor for the development of anogenital cancers. Most Arab countries lack both HPV education and national HPV vaccination programs. The objective of this study was to assess knowledge, attitudes, and acceptance toward HPV vaccination in men and women from Oman, a country in the Middle Eastern North Africa region. METHODS This cross-sectional quantitative study used convenience sampling to recruit male and female participants, aged 18 years and above from all 11 governorates of Oman to complete a validated self-administered questionnaire online in the Arabic language. The questionnaire comprised five sections, with a total of 32 questions. The questionnaire, including Arabic and English versions, was content validated and piloted. RESULTS A total of 1403 participants, including 952 parents and 369 healthcare providers, completed the survey. The results showed a lack of knowledge regarding HPV infection and vaccines, including among healthcare providers. Less than a quarter of the participants had heard of HPV infection, with digital sources of information being the most common. Factors such as being a woman or a healthcare provider or completing higher levels of education were independently and significantly positively association with HPV awareness (p < 0.001). The majority of the participants lacked vaccine safety knowledge, had concerns about the vaccine's side effects, and sought reassurance of its protection against HPV infection (62%, 71.5%, and 84.6%, respectively). Nevertheless, nearly two-thirds of the participants agreed to take the HPV vaccine, with support for both boys and girls being vaccinated. There was almost universal agreement among the participants regarding the need for parental and adolescent HPV educational programs. CONCLUSION Omani women and men showed a high level of acceptance and favorable attitude toward HPV vaccination. The study findings support future efforts to implement school and public-level HPV education and a national HPV vaccination program in Oman.

Abstract
Objectives This study aimed to assess knowledge of cervical cancer and its prevention among Omani women aged 20-65 years. Methods This cross-sectional study took place across eight primary healthcare institutions in Al Buraimi Governorate, Oman, between November 2018 and February 2019. It was carried out on the basis of a predesigned, validated and self-administered questionnaire containing 55 questions. Results Data from 791 completed questionnaires were included in the final analysis, which represents a response rate of 79.1%. The results indicated that 86.7% of surveyed women had previously heard of cervical cancer and 13.0% expected this disease to affect them in the future. The results also showed that women were less aware of the association between the human papillomavirus (HPV) and cervical cancer (24.7%). The participants considered the HPV infection and initiation of sexual intercourse below 17 years of age as the lowest risks associated with cervical cancer. Moreover, 63.8% of the participants were unaware of the availability of a vaccination 'against HPV-related cervical cancer' and many respondents were unaware of a Pap test. Those women aged over 30 years, married and with a high level of education were more likely to be aware of cervical cancer. Conclusion Generally, there was inadequate knowledge and awareness of cervical cancer among women aged 20-65 years. Young women aged 20-30 years showed relatively lesser knowledge of cervical cancer as compared to their older counterparts. Thus, concerted efforts are needed to promote such awareness among women in Oman.

High-risk human papillomaviruses and Epstein-Barr virus in breast cancer in Lebanese women and their association with tumor grade: a molecular and tissue microarray study. Cancer Cell Int 2021; 21:308.

Abstract
Background High-risk human papillomaviruses (HPVs) are present and can cooperate with Epstein–Barr virus (EBV) to initiate and/or enhance the progression of several types of human carcinomas including cervical as well as head and neck; in parallel, it has been recently pointed out that these oncoviruses can be detected in human breast cancers. Thus, we herein explored the presence/co-presence of high-risk HPVs and EBV in breast cancer in Lebanese women. Methods A cohort of 102 breast cancer samples and 14 normal breast tissues were assessed for the presence of HPVs and EBV. Polymerase chain reaction (PCR) and immunohistochemistry (IHC) analysis in addition to tissue microarray (TMA) platform were used in this study. Results We found the presence of HPV in 66/102 (65%) of our samples, while EBV is present in 41/102 (40%) of the cohort. Additionally, our data showed that high-risk HPV types (52, 35, 58, 45, 16 and 51) are the most frequent in breast cancer in Lebanese women. Meanwhile, we report that high-risk HPVs and EBV are co-present in 30/102 (29%) of the samples; more significantly, our results indicate that their co-presence is associated with tumor grade (p = 0.03). Conclusion Our data revealed that HPVs and EBV are present/co-present in human breast cancer where they may play an important role in its development and/or progression; thus, we believe that further investigations are essential to confirm and elucidate the presence/co-presence of these oncoviruses and the underlying mechanisms of their interaction in breast carcinogenesis.

Abstract
Cervical cancer is the fourth most common malignant tumor in women worldwide and is closely related to human papillomavirus (HPV). Women have the highest susceptibility to HPV-52 type in Jingzhou, China. In this study, E6-E7 sequences of 183 HPV-52 positive samples were amplified by a polymerase chain reaction and sequenced. HPV-52 E6-E7 gene variations were analyzed. The phylogenetic tree was constructed using the Kimura 2-parameter method. The secondary structure of the protein was analyzed. The selective pressure to E6-E7 genes was estimated using PAML. In addition, the B cell epitopes of the E6-E7 sequences in HPV-52 were predicted by the ABCpred server. In E6 sequences, 15 single nucleotide variants were observed, including 6 nonsynonymous variants and 9 synonymous variants. In E7 sequences, 19 single nucleotide variants occurred, including 10 nonsynonymous variants and 9 synonymous variants. Six amino acid variants, including 3 nonconservative substitutions, were found in sequences encoding the alpha helix. Eight amino acid variants, including three nonconservative substitutions, occurred in sequences encoding the strand. Through phylogenetic analysis, the E6-E7 sequences were mainly distributed in B lineage. In HPV-52 E6-E7 sequences, no positively selected site was found. The nonconservative substitutions, such as K93R, K93E in E6, T37I, and D38N in E7, affected multiple hypothetical epitopes in the B cell. This study provides information for the investigation of HPV epidemic characters. The discovery of new variants of HPV-52 may lay the basis for the development of the virus diagnosis, further study of cervical cancer, and vaccine design in Central China.

METHODS The study took place at primary healthcare institutions, Al Buraimi Governorate, Oman, between November 2018 to February 2019. In phase I, seventy items concerning cervical cancer and its prevention were generated through a literature review. In phase 2, the questionnaire was validated through calculating the content validity index (CVI) for both item level (I-CVI) and the scale level (S-CVI), in this phase a shortened English questionnaire of 55 items was formed, then rigorously translated to the Arabic language in phase III. The questionnaire was tested for reliability in two stages: A pilot and a large field test in phase IV. RESULTS A total of 55 out of 70 items formed the final version of the questionnaire. The final instrument had an S-CVI/Ave of 0.92. The questionnaire called the Knowledge in Cervical Cancer and Prevention Methods 55-items (KCCPM-55). The Cronbach alpha coefficient was 0.940 for the whole questionnaire, and ranged between 0.57 to 0.93 for each of the domains. Test-retest reliability was examined in a subsample of the total participants sample (r = 0.769, p < 0.001). CONCLUSION The KCCPM-55 has been successfully developed in the Arabic language and found to be a valid and reliable instrument for assessing the level of knowledge about cervical cancer and prevention methods among women aged 20 to 65 years in Oman.

Human Papillomavirus Infections in Cervical Samples From HIV-Positive Women: Evaluation of the Presence of the Nonavalent HPV Genotypes and Genetic Diversity. Front Microbiol 2020; 11:603657.

Abstract
Non-nonavalent vaccine (9v) Human papillomavirus (HPV) types have been shown to have high prevalence among HIV-positive women. Here, 1444 cervical samples were tested for HPV DNA positivity. Co-infections of the 9v HPV types with other HPV types were evaluated. The HPV81 L1 and L2 genes were used to investigate the genetic variability of antigenic epitopes. HPV-positive samples were genotyped using the HPVCLART2 assay. The L1 and L2 protein sequences were analyzed using a self-optimized prediction method to predict their secondary structure. Co-occurrence probabilities of the 9v HPV types were calculated. Non9v types represented 49% of the HPV infections; 31.2% of the non9v HPV types were among the low-grade squamous intraepithelial lesion samples, and 27.3% among the high-grade squamous intraepithelial lesion samples, and several genotypes were low risk. The co-occurrence of 9v HPV types with the other genotypes was not correlated with the filogenetic distance. HPV81 showed an amino-acid substitution within the BC loop (N75Q) and the FGb loop (T315N). In the L2 protein, all of the mutations were located outside antigenic sites. The weak cross-protection of the 9v types suggests the relevance of a sustainable and effective screening program, which should be implemented by HPV DNA testing that does not include only high-risk types.
