Connaissances, attitudes et croyances concernant le dépistage du cancer du col utérin dans le District d'Ajumako-Enyan-Essiam au Ghana.

L'étude a été menée dans le district d'Ajumako-Eyan-Essiam (AEED) et visait à évaluer les connaissances, attitudes et croyances des femmes relativement au dépistage du cancer du col utérin. Au Ghana, ce cancer vient au deuxième rang des causes de cancer gynécologique. Dans les études et la pratique clinique effectuées auprès de femmes atteintes de cancer du col utérin, le diagnostic précoce, le traitement et la prévention du cancer sont largement influencés par leurs connaissances et leurs attitudes envers le dépistage. À ce jour, on ne dispose pas d'étude sur ces perceptions chez les femmes dans le district d'AEED. Un devis transversal quantitatif a été utilisé avec une analyse statistique descriptive de données provenant de 240 femmes. Les résultats ont révélé que 61,3 % d'entre elles ne savaient pas quel organe était touché lors d'un cancer du col utérin ou à quel intervalle un suivi était nécessaire après un résultat de test Pap normal; il y aurait donc des lacunes dans les connaissances. Au total, 36 % croyaient que le test de Papanicolaou (test Pap) était effectué une fois pour toutes, et 57,1 % pensaient qu'il était dispendieux, ce qui limite la participation au dépistage. Par peur de l'inconnu, beaucoup de répondantes avaient refusé le dépistage (48,8 %) alors que d'autres croyaient qu'elles n'étaient pas à risque (65,8 %). De plus, bon nombre de femmes (46,7 %) pensaient qu'il n'y avait pas de traitement contre le cancer du col. En conclusion, les connaissances fausses et inadéquates de ces femmes ont influencé leurs attitudes envers le dépistage du cancer.

Awareness and attitude towards human papillomavirus and its vaccine among females with and without daughter(s) who participated in cervical cancer screening in Shenzhen, China.

OBJECTIVES: To evaluate the awareness of HPV and HPV vaccine, and willingness to be vaccinated against HPV, among women with and without daughter(s) in Shenzhen, China. METHODS: Cross-sectional survey in January and June 2015 by means of a self-administered questionnaire to collect information. Multivariate logistic regression was used to explore the factors associated with awareness of HPV and its vaccine and the willingness to be vaccinated. RESULTS: A total of 9855 women (mean age 37.09 years, SD 7.48) were included in the analysis. Although only 42.3% had heard of HPV and 21.0% of HPV vaccine, 63.3% were willing to be vaccinated. 73.9% of the 5799 women with daughter(s) were willing have their daughter(s) vaccinated. Women with daughter(s) did not have a higher awareness of HPV (43.2% vs. 41.5%, P = 0.109) and HPV vaccine (21.1% vs. 20.9%, P = 0.854) than women without daughter(s), but did tend to be more willing to be vaccinated themselves (66.3% vs. 59.9%, P < 0.001). Women's awareness of HPV and specific knowledge of HPV vaccine were predictors of the willingness to have both themselves and their daughters vaccinated. These associations may be modified by residency status, education and monthly income. CONCLUSIONS: Although awareness of HPV and HPV vaccine among women in Shenzhen was low, willingness to have themselves and their daughter(s) vaccinated was relatively high, especially among mothers. High awareness of HPV and its vaccine will help improve the acceptability of HPV vaccination according to residency status, education and monthly income.

OBJECTIFS: Evaluer la connaissance sur le VPH et du vaccin contre le VPH et la volonté de se faire vacciner contre le VPH chez les femmes avec et sans fille(s) à Shenzhen, en Chine. MÉTHODES: Enquête transversale menée en janvier et juin 2015 au moyen d'un questionnaire auto-administré destiné à recueillir des informations. La régression logistique multivariée a été utilisée pour explorer les facteurs associés à la connaissance sur le VPH et sur son vaccin et à la volonté de se faire vacciner. RÉSULTATS: 9.855 femmes (âge moyen: 37,09 ans, écart-type: 7,48) ont été incluses dans l'analyse. Bien que seulement 42,3% aient entendu parler du VPH et 21,0% du vaccin contre le VPH, 63,3% étaient prêtes à se faire vacciner. 73,9% des 5.799 femmes avec des filles ont bien voulu se faire vacciner. Les femmes avec des filles ne connaissaient pas mieux le VPH (43,2% contre 41,5%, P = 0,109) et le vaccin contre le VPH (21,1% contre 20,9%, P = 0,854) que celles sans fille(s), mais avaient tendance à être plus disposées à être vaccinées (66,3% contre 59,9%, P <0,001). La sensibilisation des femmes au VPH et leur connaissance spécifique sur le vaccin contre le VPH étaient des facteurs prédictifs de la volonté de se faire vacciner, elles et leurs filles. Ces associations pourraient être modifiées en fonction du statut de résidence, de l'éducation et du revenu mensuel. CONCLUSIONS: Bien que les femmes à Shenzhen aient été peu sensibilisées au VPH et au vaccin contre le VPH, la volonté de se faire vacciner et de faire vacciner leurs filles était relativement élevée, en particulier chez les mères. Une connaissance élevée sur le VPH et sur son vaccin contribuera à améliorer l'acceptabilité de la vaccination contre le VPH indépendamment du statut de résidence, de l'éducation et du revenu mensuel.

Association of HIV status with infection by multiple HPV types.

OBJECTIVES: To identify the clinical and demographic characteristics of HIV-positive and HIV-negative women infected by multiple HPV types. METHODS: 1399 women participated in the study (240 HIV-positive and 1159 HIV-negative women). Samples were provided for Pap tests and for HPV detection and typing by PCR. Data were collected on HPV infection, frequency of multiple infection, and HPV type distribution. Odds ratios were reported from logistic regression models. RESULTS: Compared with HIV-negative women, HIV-positive women had higher frequencies of cervical abnormality (30% vs. 20.8%), higher HPV prevalence (68.3% vs. 51.3%) and were more commonly infected with multiple HPV types (78.7% vs. 44.3%). HPV-16 was the most common type detected in the study population, with other types showing variable associations with HIV status. Positive associations were observed between infection by multiple HPV types and HIV status, cervical abnormality and having had more than three pregnancies. The odds of multiple infection by HPV types were higher in HIV-positive women who used an intrauterine device, who had a history of abortions and who had HIV viral loads >100 000 copies/ml, whilst the odds were lower in women with >500 CD4 cells/mm3 . CONCLUSIONS: HIV immunosuppression favours infection by multiple high-risk HPV types, mainly in women affected by low-grade squamous intraepithelial lesions. Antiretroviral therapy had no effect on infection by multiple HPV types. Risk factors related to progressive damage to the cervix were positively associated with infection by multiple HPV types in women living with HIV.

Genotypic characterisation of human papillomavirus infections among persons living with HIV infection; a case-control study in Kumasi, Ghana.

OBJECTIVES: The objective of this study is to describe the burden of human papillomavirus (HPV) infection among women living with HIV and non-infected women in Ghana. METHODS: A case-control study was conducted involving 107 women living with HIV aged between 18 and 59 years (cases) and 100 non-HIV-infected apparently healthy women (controls) who were recruited from the Kumasi South Hospital, from July to December, 2014. Cervicovaginal swabs were taken from study participants to characterise 28 high- and low-risk HPV genotypes using a multiplex real-time PCR. RESULTS: The overall mean age for the participants was 40.10 ± 9.76 years. The prevalence of high-risk (hr)-HPV genotypes was significantly higher among the cases than the controls (77.4% vs. 41.6%, P < 0.0001). Overall, HPV 58 and 54 were the most predominant high-risk (18.8%) and low-risk (15.0%) genotypes detected. The two most common hr-HPV genotype isolates were 58 (18.8%) and 35 (15.9%) with 58 being the most prevalent among age group 35-44 years compared with hr-HPV 16, 18, 35 and 45, found predominantly among 18-34 age group. CONCLUSIONS: Significant variations exist in HPV genotypes among HIV-infected and uninfected women.

Human papillomavirus distribution in invasive cervical carcinoma in sub-Saharan Africa: could HIV explain the differences?

OBJECTIVES: To describe human papillomavirus (HPV) distribution in invasive cervical carcinoma (ICC) from Mali and Senegal and to compare type-specific relative contribution among sub-Saharan African (SSA) countries. METHODS: A multicentric study was conducted to collect paraffin-embedded blocks of ICC. Polymerase chain reaction, DNA enzyme immunoassay and line probe assay were performed for HPV detection and genotyping. Data from SSA (Mozambique, Nigeria and Uganda) and 35 other countries were compared. RESULTS: One hundred and sixty-four ICC cases from Mali and Senegal were tested from which 138 were positive (adjusted prevalence = 86.8%; 95% CI = 79.7-91.7%). HPV16 and HPV18 accounted for 57.2% of infections and HPV45 for 16.7%. In SSA countries, HPV16 was less frequent than in the rest of the world (49.4%vs. 62.6%; P < 0.0001) but HPV18 and HPV45 were two times more frequent (19.3%vs. 9.4%; P < 0.0001 and 10.3%vs. 5.6%; P < 0.0001, respectively). There was an ecological correlation between HIV prevalence and the increase of HPV18 and the decrease of HPV45 in ICC in SSA (P = 0.037 for both). CONCLUSION: HPV16/18/45 accounted for two-thirds of the HPV types found in invasive cervical cancer in Mali and Senegal. Our results suggest that HIV may play a role in the underlying HPV18 and HPV45 contribution to cervical cancer, but further studies are needed to confirm this correlation.

Human papillomavirus detection using in situ hybridization and correlations with histological and cytological findings.

BACKGROUND AND OBJECTIVE: The human papillomavirus (HPV) is the main causative agent of cancerous and precancerous lesions in cervical cancers. The infection detection is performed by cytological and histological examination. However, molecular testing for HPV infection remains necessary to distinguish nonspecific inflammatory lesions from HPV-related lesions. We aimed to compare cytological and histological diagnosis of HPV lesions and to confront histological findings with molecular detection of HPV by in situ hybridization (ISH). MATERIAL AND METHODS: A total of 2399 pap smears were collected between 1997 and 2002. Twenty-nine of them presented with lesions indicative of HPV infection. Colposcopy and biopsy were performed on 23 of these 29 pap smears, with a comparison of the cytological and histological findings. Molecular testing for HPV by ISH was performed on 11 pap smears. RESULTS: A 79% cytological and histological agreement was observed. ISH revealed the presence of the virus in seven case patients, amounting to a 63% histological and molecular agreement. Seven HPV genotypes were categorized (6-11-16-18-31-33-51). CONCLUSION: HPV detection by ISH adds little to the diagnosis of HPV-associated lesions based on cytological and histological features. It, however, helps improve the specificity of the diagnosis and determine the viral genotype which, in turn, helps better define the lesion prognosis.
