    Human papillomavirus (HPV) vaccines containing types 16 and 18 are likely to be effective in preventing cervical cancer associated with these HPV types. No information currently exists in Botswana concerning the HPV types causing precancerous or cancerous lesions. Our goal was to determine the prevalence of HPV types associated with precancerous cervical intraepithelial neoplasia (CIN) stages 2 and 3 in HIV-infected women in Gaborone, Botswana. HIV-infected women referred to our clinic with high-grade intraepithelial lesion on the Pap smear were enrolled in the study. HPV typing was only performed if the histopathology results showed CIN stage 2 or 3 disease using linear array genotyping (CE-IVD, Roche Diagnostics).One hundred HIV-infected women were identified with CIN stages 2 or 3 between August 11, 2009 and September 29, 2010. Eighty-two of 100 women enrolled had coinfection by multiple HPV subtypes (range, 2 to 12). Of the remaining 18 women, 14 were infected with a single high-risk subtype and 4 had no HPV detected. Overall, 92 (92%) women were infected with at least 1 high-risk HPV subtype, and 56 were coinfected with more than 1 high-risk HPV type (range, 2 to 5). Fifty-one (51%) women had HPV subtypes 16, 18, or both. HPV 16 and 18 are the most common types in HIV-infected women with CIN 2 or 3 in Gaborone, Botswana, suggesting that the implementation of HPV vaccination programs could have a significant impact on the reduction of cervical cancer incidence. However, given the relative lack of knowledge on the natural history of cervical cancer in HIV-infected women and the significant prevalence of infection and coinfection with other high-risk HPV types in our sample, the true impact and cost-effectiveness of such vaccination programs need to be evaluated.

    Use of Mobile Telemedicine for Cervical Cancer Screening
    (2011-06-01) Gormley, Rachel H; Ratcliffe, Sarah; Quinley, Kelly E; Steiner, Ann; Ramogola-Masire, Doreen; Kovarik, Carrie; Shih, Ting; Szep, Zsofia
    Visual inspection of the cervix with application of 4% acetic acid (VIA) is an inexpensive alternative to cytology-based screening in areas where resources are limited, such as in many developing countries. We have examined the diagnostic agreement between off-site (remote) expert diagnosis using photographs of the cervix (photographic inspection with acetic acid, PIA) and in-person VIA. The images for remote evaluation were taken with a mobile phone and transmitted by MMS. The study population consisted of 95 HIV-positive women in Gaborone, Botswana. An expert gynaecologist made a definitive positive or negative reading on the PIA results of 64 out of the 95 women whose PIA images were also read by the nurse midwives. The remaining 31 PIA images were deemed insufficient in quality for a reading by the expert gynaecologist. The positive nurse PIA readings were concordant with the positive expert PIA readings in 82% of cases, and the negative PIA readings between the two groups were fully concordant in 89% of cases. These results suggest that mobile telemedicine may be useful to improve access of women in remote areas to cervical cancer screening utilizing the VIA `see-andtreat' method.

    A Cross-Sectional Study of HPV Vaccine Acceptability in Gaborone, Botswana

    Background Cervical cancer is the most common cancer among women in Botswana and elsewhere in Sub-Saharan Africa. We sought to examine whether HPV vaccine is acceptable among parents in Botswana, which recently licensed the vaccine to prevent cervical cancer. Methods and Findings We conducted a cross-sectional survey in 2009, around the time the vaccine was first licensed, with adults recruited in general medicine and HIV clinics in Gaborone, the capital of Botswana. Although only 9% (32/376) of respondents had heard of HPV vaccine prior to the survey, 88% (329/376) said they definitely will have their adolescent daughters receive HPV vaccine. Most respondents would get the vaccine for their daughters at a public or community clinic (42%) or a gynecology or obstetrician's office (39%), and 74% would get it for a daughter if it were available at her school. Respondents were more likely to say that they definitely will get HPV vaccine for their daughters if they had less education (OR = 0.20, 95% CI = 0.07–0.58) or lived more than 30 kilometers from the capital, Gaborone (OR = 2.29, 95% CI = 1.06–4.93). Other correlates of acceptability were expecting to be involved in the decision to get HPV vaccine, thinking the vaccine would be hard to obtain, and perceiving greater severity of HPV-related diseases. Conclusions HPV vaccination of adolescent girls would be highly acceptable if the vaccine became widely available to the daughters of healthcare seeking parents in Gaborone, Botswana. Potential HPV vaccination campaigns should provide more information about HPV and the vaccine as well as work to minimize barriers.
